Strategy for reconstruction of irreparable rotator cuff tears / 国际外科学杂志

Rotator cuff tears are very common in middle-aged and older adults and are the leading cause of shoulder surgery in the population. Some patients have rotator cuff tears that are classified as irreparable tears due to the large size of the tear and severe muscle atrophy. The treatment of irreparable rotator cuff tears presents great challenges. How to reconstruct the function of the shoulder joint is the key point. In this review article, authors will focus on partial repair of irreparable rotator cuff tears and tendon transfer for rotator cuff reconstruction, paying attention to its scope of application, efficacy, advantages and disadvantages, and providing reference for clinical diagnosis and treatment.

Effects of oxytocin induction on early postpartum hemorrhage, perineal integrity, and breastfeeding: a case-control study

SUMMARY OBJECTIVE: The aim of this study was to evaluate the postpartum hemorrhage, perineal integrity, and breastfeeding results of mothers who underwent oxytocin induction in the first stage of labor in the early postpartum period. METHODS: This single-center observational case-control study was conducted in the obstetric unit of a public hospital in Istanbul. The study sampling included 44 pregnant women who received oxytocin induction (case group) and 44 pregnant women who did not receive oxytocin (control group). The Personal Information Form, LATCH Breastfeeding Assessment Tool, Breastfeeding Self-Efficacy Scale, Redness, Edema, Ecchymosis, Discharge, and Approximation Scale, and Postpartum Hemorrhage Collection Bag were used in data collection, and pad follow-up was carried out. RESULTS: The amount of hemorrhage in the first 24 h of the postpartum period and the mean Redness, Edema, Ecchymosis, Discharge, and Approximation Scale score were significantly higher in the case group. While 47.7% of the oxytocin-induced women had 1st or 2nd, and 11.4% had 3rd or 4th degrees of lacerations, 20.5% of the control group had 1st or 2nd, and 2.3% had 3rd or 4th degrees of lacerations. There was no significant difference between the mean scores of the Breastfeeding Self-Efficacy Scale and LATCH Breastfeeding Assessment Tool in both groups. CONCLUSION: According to the study findings, it was determined that oxytocin induction administered in the first stage of labor increased hemorrhage and perineal trauma in the early postpartum period but did not affect the results of breastfeeding. Clinical Trial Registration Number: NCT04441125.

Laceração de canalículo lacrimal em centro de referência do centro-oeste paulista / Lacrimal canaliculus laceration in a reference center in the Center-West of the state of São Paulo

RESUMO Objetivo: Descrever as características clínico-epidemiológicas, técnicas cirúrgicas e resultado do tratamento das lacerações canaliculares operadas em nosso serviço. Métodos: Estudo retrospectivo, realizado de janeiro de 2012 a junho de 2020, considerando-se as lesões de canalículo lacrimal operadas em um serviço de referência. Dados demográficos, características das lesões, detalhes das cirurgias e resultado do tratamento foram obtidos de prontuários eletrônicos e analisados estatisticamente. Resultados: Foram incluídos 26 portadores de lesões canaliculares, com idade entre 2 e 71 anos, sendo 73,1% homens. A lesão acometia o canalículo superior em 53,9%; 80,8% pacientes procuraram pelo serviço nas primeiras 24 horas, e 46,2% tiveram a cirurgia realizada entre 24 e 72 horas após o traumatismo. Todos os pacientes tiveram intubação mono ou bicanalicular, e o tempo transcorrido entre a cirurgia e a retirada do silicone, variou de zero a 183 dias. Após a cirurgia, 21 pacientes (80,8%; p<0,05) não apresentaram complicações, 2 (7,7%) evoluíram com obstrução canalicular, 2 (7,7%) com granuloma e 1 (3,8%) com ectrópio de ponto lacrimal. Conclusão: As lesões de canalículo encontradas em nossa prática são mais comuns em crianças ou homens jovens, acometem mais o canalículo superior e as nossas condutas levam a sucesso no tratamento na maior parte dos casos. As grandes controvérsias no assunto persistem, como o tipo e o tempo de permanência do tubo de silicone na via lacrimal. Somente estudos com grandes amostras podem consolidar esses conceitos.

ABSTRACT Objective: To describe the clinical and epidemiological characteristics, surgical techniques, and results of the canalicular laceration treatment at our service. Methods: A retrospective study was carried out from January 2012 to June 2020, considering canalicular injuries operated at a reference center. Demographic data, lesion characteristics, surgical details, and treatment outcomes were obtained from electronic medical records and were statistically analyzed. Results: Twenty-six cases of people with canalicular lesions aged between 2 to 71 years old were included, of whom 73.1% were men. The superior canaliculus was affected in 53.9%; 80.8% of patients searched for care within the first 24 hours, and 46.2% had the surgery performed between 24-72 hours after trauma. All patients had mono or bicanalicular intubation and the time elapsed between surgery and silicone removal ranged from 0 to 183 days. After surgery, 21 patients (80.8%, p<0.05) did not present any complications, two (7.7%) evolved with canalicular obstruction, two (7.7%) with granuloma, and one (3.8 %) with lacrimal puncta ectropion. Conclusion: In our practice, canalicular injuries are more common in children or young men, affecting mainly the superior canaliculus, and treatment success using our approach can be achieved in most of the cases. However, great controversies remain on the subject, such as type of intubation and when to remove the silicone tube from the lacrimal pathway. Larger series are required to consolidate controversial concepts.

Preoperative promestriene for hysteroscopy: a randomized clinical trial

SUMMARY OBJECTIVE: Intraoperative complications of hysteroscopy, such as the creation of a false passage, cervix dilatation failure, and uterine perforation, may require suspension of the procedure. Some patients refuse a new procedure, which delays the diagnosis of a possible serious uterine pathology. For this reason, it is essential to develop strategies to increase the success rate of hysteroscopy. Some authors suggest preoperative use of topical estrogen for postmenopausal patients. This strategy is common in clinical practice, but studies demonstrating its effectiveness are scarce. The aim of this study was to evaluate the effect of cervical preparation with promestriene on the incidence of complications in postmenopausal women undergoing surgical hysteroscopy. METHODS: This is a double-blind clinical trial involving 37 postmenopausal patients undergoing surgical hysteroscopy. Participants used promestriene or placebo vaginally daily for 2 weeks and then twice a week for another 2 weeks until surgery. RESULTS: There were 2 out of 14 (14.3%) participants with complications in the promestriene group and 4 out of 23 (17.4%) participants in the placebo group (p=0.593). The complications were difficult cervical dilation, cervical laceration, and vaginal laceration. CONCLUSION: Cervical preparation with promestriene did not reduce intraoperative complications in postmenopausal patients undergoing surgical hysteroscopy.

Pediatric canalicular laceration repair using the Mini Monoka versus Masterka monocanalicular stent / Correção de laceração canalicular pediátrica usando os stents monocanaliculares Mini-Monoka versus Masterka

ABSTRACT Purpose: One of the most important disadvantages of using Mini Monoka stents in pediatric canalicular laceration repair is premature stent loss. In this study, we aimed to compare clinical outcomes between the use of Mini Monoka and Masterka monocanalicular stents in children and discuss the potential causes of premature stent loss. Methods: The medical records of 36 patients who underwent surgical repair of canalicular lacerations were retrospectively reviewed. Children aged <18 years who underwent canalicular laceration repair with either Mini Monoka or Masterka and had at least 6 months of follow-up after stent removal were included in the study. The patients' demographics, mechanism of injury, type of stent used, premature stent loss, and success rate were analyzed. Success was defined as stent removal without subsequent epiphora and premature stent loss. Results: Twenty-seven children fulfilled our study criteria, and their data were included in the analyses. Mini Monoka was used in 14 patients (51.9%), whereas Masterka was used in 13 patients (48.1%). The preoperative clinical features, including age, sex, and mechanism of injury, were similar between the two groups. The mean age was 8.3 ± 5.5 years in the Mini Monoka group and 7.8 ± 5.9 years in the Masterka group (p=0.61). Three patients in the Mini Monoka group (21.4%) underwent reoperation due to premature stent loss. No premature stent loss was observed in the Masterka group. As a result, the rate of success was 78.6% in the Mini Monoka group, whereas it was 100% in the Masterka group (p=0.22). Conclusions: Even though the two groups did not show any statistically significant difference in success rate, we did not observe any premature stent loss in the Masterka group. Further studies with larger and randomized series are warranted to elaborate on these findings.

RESUMO Objetivo: Uma das desvantagens mais importantes do uso de stents Mini Monoka no reparo de lacerações canaliculares pediátricas é a perda prematura do stent. Neste estudo, objetivamos comparar os resultados clínicos dos stents monocanaliculares Mini Monoka e Masterka em crianças e discutir as possíveis causas da perda prematura do stent. Métodos: Foram incluídos nesta revisão retrospectiva 36 pacientes <18 anos de idade que se submeteram ao reparo cirúrgico de uma laceração canalicular com um stent Mini Monoka ou Masterka e tiveram pelo menos 6 meses de acompanhamento após a remoção do stent. Foram analisados os dados demográficos, o mecanismo da lesão, o tipo de stent utilizado, a ocorrência de perda prematura de stent e o sucesso da intervenção. O sucesso foi definido como a ausência de epífora após a remoção do stent, sem a perda prematura deste. Resultados: Vinte e sete pacientes preencheram os critérios do presente estudo e foram incluídos nas análises. O stent Mini Monoka foi usado em 14 pacientes (51,9%), enquanto o Masterka foi usado em 13 pacientes (48,1%). As características clínicas pré-operatórias, incluindo idade, sexo e mecanismo de lesão, foram semelhantes entre os dois grupos. A média de idade foi de 8,3 ± 5,5 anos no grupo Mini Monoka e de 7,8 ± 5,9 anos no grupo Masterka (p=0,61). Três pacientes do grupo Mini-Monoka (21,4%) tiveram que ser operados novamente por perda prematura do stent. Nenhuma perda prematura do stent foi observada no grupo Masterka. Como resultado, a taxa de sucesso foi de 78,6% no grupo Mini Monoka e de 100% no grupo Masterka (p=0,22). Conclusões: Embora nenhuma diferença estatisticamente significativa tenha sido detectada entre os dois grupos em termos de taxas de sucesso, não observamos nenhuma perda prematura de stent no grupo Masterka. São necessários mais estudos, com séries maiores e randomizadas, para chegar a maiores conclusões sobre esses achados.

Effectiveness and safety of all-suture anchors and single-row suture anchors for rotator cuff repair: a prospective randomized controlled study / 中华创伤杂志

Objective:To compare the effectiveness and safety of all-suture anchors and single-row suture anchors for rotator cuff repair.Methods:A prospective randomized controlled study was conducted to analyze the clinical data of 50 patients with rotator cuff tear admitted to Second Affiliated Hospital of Zhejiang University School of Medicine between July 2019 and September 2021. They were divided into two groups according to the random table: 25 patients to receive repair with single-row suture anchors (control group) and the other 25 with all-suture anchors (trial group). Visual Analogue Scale (VAS), University of California, Los Angeles (UCLA) shoulder score, American Shoulder and Elbow Surgeons (ASES) score and shoulder range of motion were compared between the two groups before surgery, at 3 months after surgery and at the last follow-up. The rotator cuff retear rate of the two groups was evaluated according to Sugaya classification at 6 months after surgery. Breakage or anchor loosening during surgery, healing of incision and presence of infections or neurological complications after surgery, and change of the anchor position and periosteal reaction at the insertion site at 3 and 6 months after surgery were observed in the two groups.Results:A total of 50 patients with rotator cuff tear were involved in this study, including 17 males and 33 females, aged 40-73 years [(59.1±10.3)years]. All patients were followed up for 6-9 months [(6.7±1.0)months]. The differences in VAS, UCLA shoulder score, ASES score, and shoulder range of motion between the two groups were statistically insignificant before surgery (all P>0.05). The VAS at 3 months after surgery and at the last follow-up in the control group was 2.0 (2.0, 4.0)points and 2.0 (0.0, 2.0)points, respectively, with no statistical differences from 2.0 (2.0, 2.0)points and 2.0 (0.0, 2.0)points in the trial group (all P>0.05). In the control group, the UCLA shoulder score and ASES score at 3 months after surgery and the ASES score at the last follow-up were (25.1±4.5)points, 78.8 (71.6, 85.8)points and 85.8 (85.8, 93.0)points, respectively, with no statistical differences from (26.8±4.7)points, 85.8 (82.3, 85.8)points, and 92.8 (85.8, 100.0)points in the trial group (all P>0.05). At the last follow-up, the UCLA shoulder score of the control group was (29.2±3.9)points, which was lower than that of the trial group [(31.6±2.4)points] ( P<0.05). The differences in shoulder motion between the two groups at 3 months after surgery and at the last follow-up were not statistically significant (all P>0.05). The VAS, UCLA shoulder score, and ASES score at 3 months after surgery and at the last followup in both groups were significantly improved compared to their preoperative values (all P<0.05); further improvements were observed at the last follow-up compared with those at 3 months after surgery (all P<0.05). The rotator cuff retear rate at 6 months after surgery was 16.7% (4/24) in the control group, not statistically different from 4.3% (1/23) in the trial group ( P>0.05). There were no incidences of anchor loosening or breakage during surgery. All incisions were healed after surgery, with no infections or neurological complications. No grades II to III periosteal reactions at the anchor insertion sites were observed in either group at 3, 6 months after surgery. The percentage of patients with grade 0 periosteal reaction at the anchor insertion site at 3 months after surgery was 4.2% (1/24) in the control group, significantly lower than 30.4% (7/23) in the trial group ( P<0.05). Conclusion:All-suture anchors and single-row suture anchors are effective in rotator cuff repair, but the former results in better shoulder function and fewer periosteal reactions in the anchor insertion site in the early stage.

Research progress in diagnosis and treatment of partial thickness rotator cuff tears / 国际外科学杂志

Partial thickness rotator cuff tears(PTRCTs) are a common cause of shoulder pain and dysfunction in adults, which are seen in middle-aged and older adults and young adults in over-the-shoulder sports(throwing sports are the most common). PTRCTs include partial tears on the articular side, partial tears on the bursal side, and intratendinous tears. Tears on the articular side are 2-3 times more likely than on the bursal side, but intratendinous tears are the most common type. The treatment of PTRCTs consists of both conservative and surgical treatments. Conservative treatment is suitable for most patients with PTRCTs, and recommended as the primary treatment for PTRCTs because of its good clinical efficacy and patients′ willingness to accept it. However, there is no genaral consensus on the best treatment and the results reported in the literature are controversial. In this paper, the anatomy, epidemiology, pathogenic factor, diagnosis and treatment progress of PTRCTs are summarized in light of relevant domestic and international studies in recent years to provide reference for clinical diagnosis and treatment.

Comparison of medium-term clinical effects of arthroscopic double row repair between traumatic and degenerative medium supraspinatus tear / 中华创伤骨科杂志

Objective:To compare the medium-term clinical effects of arthroscopic double row repair between traumatic and degenerative medium supraspinatus tear.Methods:A retrospective study was conducted to analyze the clinical data of 23 patients who had been treated for traumatic or degenerative medium supraspinatus tear by the same arthroscopic double row repair and postoperative rehabilitation at Sports Medicine Center, The First Hospital Affiliated to Army Medical University between January 2015 and August 2020. They were assigned into 2 groups according to different tears. In the traumatic group of 8 cases of traumatic medium supraspinatus tear, there were 5 males and 3 females with an age of (46.1±4.3) years and a tear size of (1.3±1.0) cm 2. In the degenerative group of 15 cases of degenerative medium supraspinatus tear, there were 4 males and 11 females with an age of (59.9±8.1) years and a tear size of (4.1±1.1) cm 2. At preoperation and the last follow-up, the shoulder pain was evaluated by visual analogue scale (VAS), and the shoulder function by American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score and Simple Shoulder Test (SST); the improvements in active range of motion (ROM) of the shoulder were recorded at the last follow-up. Results:The 2 groups were comparable because there was no significant difference between them in the general clinical data ( P>0.05). The traumatic and degenerative groups were followed up for (40.3±11.2) and (36.4±12.4) months, respectively. At the last follow-up, the improvements in range of anterior flexion and internal rotation vertebral rank in the degenerative group [55.3°±33.6° and (4.1±1.3) ranks] were significantly greater than those in the traumatic group [27.5°±22.5° and (2.3±1.9) ranks] ( P<0.05). At the last follow-up, the VAS, ASES, Constant-Murley, and SST scores in the degenerative group were improved respectively by (3.7±0.8), (40.9±14.0), (38.4±9.4), and (6.5±1.4) points compared with their preoperative values, significantly greater than those in the traumatic group [(2.3±0.7), (19.6±14.6), (19.2±7.9), and (3.8±0.7) points] ( P<0.05). Conclusion:Arthroscopic double row repair can achieve significant medium-term improvements in shoulder function for both traumatic and degenerative medium supraspinatus tears, but the improvements may be grater for the degenerative ones.

Resultados del taller para residentes de ginecoobstetricia en reparación de episiotomías y desgarros obstétricos / Results of workshop for obstetrics and gynecology residents on episiotomy and injury obstetric tear repair

Resumen OBJETIVO: Evaluar los conocimientos, satisfacción y nivel de confianza de los médicos residentes de Ginecología y Obstetricia luego de haber participado en un taller de simulación de reparación de episiotomías y desgarros perineales severos. MATERIALES Y MÉTODOS: Estudio observacional y transversal efectuado en residentes de la especialidad de Ginecología y Obstetricia en junio del 2022. Se aplicaron cuestionarios de conocimientos antes y después del taller, una encuesta de satisfacción y nivel de confianza, así como una lista de cotejo para valorar el desempeño en la ejecución de la técnica de reparación de episiotomías y desgarros. Se utilizó estadística descriptiva y prueba de t pareada para la comparación antes y después de las muestras relacionadas. Se consideró significancia estadística una p < 0.05. RESULTADOS: Se incluyeron 37 médicos residentes de todos los grados académicos. La media de la evaluación preprueba fue de 14.89 ± 0.54 puntos y 15.81 ± 0.41 puntos en la posprueba (p = 0.233). Durante la práctica de reparación de la episiotomía, 34 de los 37 residentes reconocieron estructuras anatómicas y todos seleccionaron adecuadamente el material de sutura. En el taller de desgarros perineales 25 de 37 reconocieron las estructuras anatómicas y todos, menos uno, seleccionaron adecuadamente el material. CONCLUSIONES: El taller con modelos animales de simulación tiene un alto grado de satisfacción y nivel de confianza; sin embargo, en este estudio no se observó mejoría en los conocimientos. Este efecto positivo en los médicos en vías de especialización permite identificar, de manera oportuna, las lesiones del esfínter anal, llevar a cabo una correcta reparación y, en consecuencia, disminuir la incidencia de disfunciones asociadas con el traumatismo obstétrico perineal.

Abstract OBJECTIVE: To assess the knowledge, satisfaction and level of confidence of Gynaecology and Obstetrics residents after participating in a simulation workshop on episiotomy and severe perineal tear repair. MATERIALS AND METHODS: Observational and cross-sectional study carried out in residents of the speciality of Gynaecology and Obstetrics in June 2022. Knowledge questionnaires were administered before and after the workshop, a satisfaction and confidence level survey, as well as a checklist to assess the post-workshop episiotomy and tear repair technique. Descriptive statistics and paired t-test were used for pre- and post-test comparison. A p < 0.05 was considered statistically significant. RESULTS: Thirty-seven resident physicians of all academic grades were included. The mean pre-test assessment was 14.89 ± 0.54 points and 15.81 ± 0.41 points at post-test, p = 0.233. During episiotomy repair practice, 34 of the 37 residents recognized anatomical structures and all selected suture material appropriately. In the perineal tears workshop 25 of 37 recognized anatomical structures and all but one selected material appropriately. CONCLUSIONS: The workshop with simulation animal models has a high satisfaction and confidence level; however, no improvement in knowledge was observed in this study. This positive effect on trainee doctors allows early identification of anal sphincter injuries, correct repair and consequently a decrease in the incidence of dysfunction associated with perineal obstetric trauma.

Systematic reviews were conducted according to the Cochrane handbook and GRADE was used to assess the quality and certainty of the evidence. Detailed recommendations are provided for 19 clinical questions in the prevention and management of perineal laceration, aiming to guide clinical practice and improve the quality of life of this group of women.

Application of unprotected perineum delivery technique for natural childbirth in primiparas / 中国基层医药

Objective:To investigate the application effects of unprotected perineum delivery technique for normal vaginal delivery in primiparas.Methods:A total of 260 primiparas who underwent natural childbirth in Tengzhou Central People's Hospital between January 2019 and September 2020 were included in this study. They were randomly assigned to undergo childbirth either with an unprotected perineum delivery technique (study group, n = 130) or the conventional delivery technique (control group, n = 130). Delivery-related indicators were compared between the two groups. Results:The rate of first-degree perineal tear in the study and control groups was 71.52% and 29.23%, respectively, the rate of second-degree perineal tear were 7.16% and 3.16%, respectively, and the episiotomy rate in the two groups were 21.32% and 67.51%, respectively. There were significant differences in rate of first-degree perineal tear, rate of second-degree perineal tear and episiotomy rate between the two groups ( χ2 = 7.19, 7.03, 8.35, all P < 0.05). The length of hospital stay in the study and control group was 3.27 ± 5.79 days and 5.18 ± 7.26 days, respectively. The numerical rating scale score of postpartum perineal pain in the two groups was 1.23 ± 2.51 points and 3.24 ± 2.79 points, respectively. The incidence of postpartum complications was 3.33% and 11.67%, respectively. There were significant differences in length of hospital stay, numerical rating scale score of postpartum perineal pain and incidence of postpartum complications between the two groups ( t = 2.23, 2.06, χ2 = 2.52, all P < 0.05). There were no significant differences in length of second stage of labor and Apgar score in new born infants between the study and control groups (all P > 0.05). Conclusion:Unprotected perineum delivery technique can greatly decrease episiotomy rate, alleviate perineal tear, reduce pain, reduce complications, shorten length of hospital stay, and improve quality of obstetric care.

Risk factors for rotator cuff tear and corresponding prediction efficacy / 中华创伤杂志

Objective:To analyze the risk factors for rotator cuff tear and evaluate the corresponding prediction efficacy.Methods:A case-control study was conducted in 69 patients with rotator cuff tear admitted to Affiliated Hospital of Qingdao University from June 2020 to June 2021 (rotator cuff tear group) and 51 normal volunteers or medical examiners (normal control group). There were 55 males and 65 females, with the age range of 34-77 years [(58.2±7.2)years]. Body mass index (BMI) ranged from 19.5-32.4 kg/m 2 [(25.4±2.5)kg/m 2]. Univariate analysis was performed for the correlation of gender, age, history of hypertension, history of smoking, history of diabetes, BMI, angle of humeral greater tuberosity and notch angle of humeral greater tuberosity with rotator cuff tear in the two groups. Factors with statistically significant differences were included in multivariate Logistic regression analysis to determine the independent risk factors for rotator cuff tear. Spearman correlation analysis was used to find factor correlation between the two groups. The receiver operating characteristic (ROC) curve of relevant factors for the diagnosis and prediction of rotator cuff tear was analyzed. Results:Univariate analysis showed that age, angle of humeral greater tuberosity and notch angle of humeral greater tuberosity related to rotator cuff tear (all P<0.05). On the contrary, gender, history of hypertension, history of smoking, history of diabetes and BMI were not correlated with rotator cuff tear (all P>0.05). Multivariate Logistic regression analysis showed significant correlations of angle of humeral greater tuberosity and notch angle of humeral greater tuberosity with rotator cuff tear (all P<0.05). Spearman correlation analysis showed that age was not correlated with angle of humeral greater tuberosity and notch angle of humeral greater tuberosity ( r=0.09, 0.13, all P>0.05), but there was significant positive correlation between angle of humeral greater tuberosity and notch angle of humeral greater tuberosity ( r=0.76, P<0.01). When the optimal cutoff values of angle of humeral greater tuberosity and notch angle of humeral greater tuberosity were 70.05° and 150.55°, the area under the ROC curve (AUC) for predicting rotator cuff tear was 0.79 (95% CI 0.71-0.87, P<0.01) and 0.81 (95% CI 0.74- 0.89, P<0.01). Conclusions:Angle of humeral greater tuberosity and notch angle of humeral greater tuberosity are independent factors for rotator cuff tear, and larger angles suggest higher prevalence of rotator cuff tear. Besides, the notch angle of humeral greater tuberosity has relatively better predictive performance.

Influencing factors for shoulder stiffness after rotator cuff tear / 中华创伤骨科杂志

Objective:To study the influencing factors for shoulder stiffness after rotator cuff tear.Methods:The data of 228 patients were retrospectively analyzed who had been diagnosed with rotator cuff tear by arthroscopic surgery at Department of Articular Surgery, Hospital Affiliated to Chengde Medical College from June 2019 to May 2021. Their baseline data were recorded immediately after admission, including possible risk factors for shoulder stiffness. The patients were divided into a stiffness group and a non-stiffness group based on passive range of motion of shoulder joint. Univariate and multivariate analyses were performed to find out the influencing factors for shoulder stiffness after rotator cuff tear.Results:Preliminary univariate analysis showed that advanced age, smoking history, misdiagnosis history, no standardized physiotherapy history, high body mass index (BMI) and long duration of disease were all likely risk factors for shoulder stiffness in patients with rotator cuff tear ( P<0.05). Multivariate analysis confirmed that advanced age( OR=1.474, 95% CI: 1.013~2.145, P=0.043), smoking history( OR=2.239, 95% CI: 1.147~4.368, P=0.018), no standardized physiotherapy history( OR=0.167, 95% CI: 0.065~0.424, P<0.001), high BMI( OR=3.029, 95% CI: 1.657~5.536, P<0.001) and long duration of disease ( OR=1.775, 95% CI: 1.384~2.276, P<0.001) were the risk factors for shoulder stiffness. Conclusion:Age>60 years, smoking history, misdiagnosis history, no standardized physiotherapy history, high body mass index and long course of disease may be the important influencing factors for shoulder stiffness after rotator cuff tear.

Massagem perineal pré-natal para prevenção do trauma: piloto de ensaio clínico randomizado / Masaje perineal prenatal para la prevención del trauma: piloto de ensayo clínico aleatorizado / Antenatal perineal massage for trauma prevention: a pilot randomized clinical trial

Resumo Objetivo Avaliar a adesão de gestantes e acompanhantes à realização da massagem perineal digital durante a gestação e seu efeito na prevenção do trauma perineal no parto e na redução de morbidade associada nos 45 e 90 dias pós-parto. Métodos Estudo piloto de ensaio clínico randomizado com 153 gestantes de risco habitual, 78 mulheres no grupo de intervenção realizaram a massagem perineal digital e 75 mulheres do grupo controle receberam os cuidados habituais. Para a análise do desfecho principal (trauma perineal) e dos desfechos secundários, permaneceram em cada grupo 44 mulheres que tiveram parto vaginal. A intervenção foi realizada pela gestante ou acompanhante de sua escolha, diariamente, a partir de 34 semanas de gestação, por 5 a 10 minutos. Resultados A massagem perineal foi fator de proteção para edema nos primeiros 10 dias pós-parto (RR 0,64 IC95%0,41-0,99) e perda involuntária de gases nos 45 dias pós-parto (RR0,57 IC95%0,38-0,86). O ajuste residual ≥ 2 observado na análise das condições do períneo pós-parto mostrou uma tendência das mulheres do grupo intervenção terem períneo íntegro. As mulheres e os acompanhantes que realizaram a massagem perineal aceitaram bem a prática, recomendariam e fariam novamente em futura gestação. Conclusão A massagem perineal digital realizada diariamente, a partir de 34 semanas de gestação, foi uma prática bem aceita pelas mulheres e acompanhantes deste estudo. Apesar de não proteger a mulher de trauma perineal, esta prática reduziu o risco de edema 10 dias pós-parto e incontinência de gases 45 dias pós-parto.

Resumen Objetivo Evaluar la participación de mujeres embarazadas y acompañantes en la realización del masaje digital perineal durante el embarazo y su efecto en la prevención del trauma perineal durante el parto y en la reducción de la morbilidad asociada con los 45 y 90 días post parto. Métodos Estudio piloto de ensayo clínico aleatorizado con 153 mujeres embarazadas con riesgo normal, 78 mujeres en el grupo de intervención realizaron el masaje digital perineal y 75 mujeres del grupo control recibieron los cuidados habituales. Para el análisis del desenlace principal (trauma perineal) y de los desenlaces secundarios, permanecieron en cada grupo 44 mujeres que tuvieron parto vaginal. La intervención la realizó la mujer embarazada o el acompañante por ella elegido, diariamente, a partir de las 34 semanas de embarazo, por 5 a 10 minutos. Resultados El masaje perineal fue factor de protección para el edema en los primeros 10 días postparto (RR 0,64 IC95%0,41-0,99) y la pérdida involuntaria de gases en los 45 días post parto (RR0,57 IC95%0,38-0,86). El ajuste residual ≥ 2 observado en el análisis de las condiciones del perineo postparto mostró una tendencia en las mujeres del grupo intervención a que tengan el perineo íntegro. Las mujeres y los acompañantes que realizaron el masaje perineal recibieron bien la práctica, la recomendarían y la harían nuevamente en un futuro embarazo. Conclusión El masaje digital perineal realizado diariamente, a partir de las 34 semanas de embarazo, fue una práctica bien recibida por las mujeres y acompañantes de este estudio. Pese a que no protege a la mujer de un trauma perineal, esta práctica redujo el riesgo de edema a los 10 días post parto y la incontinencia de gases 45 días post parto.

Abstract Objective To evaluate the adherence of pregnant women and companions to the performance of digital perineal massage during pregnancy and its effect on the prevention of perineal trauma during childbirth and on the reduction of associated morbidity at 45 and 90 days postpartum. Methods A pilot study of a randomized clinical trial with 153 normal risk pregnant women; 78 women in the intervention group underwent digital perineal massage and 75 women in the control group received usual care. For the analysis of the main outcome (perineal trauma) and secondary outcomes, 44 women who had vaginal delivery remained in each group. The intervention was performed daily by the pregnant woman or the companion of her choice from 34 weeks of gestation during 5-10 minutes. Results Perineal massage was a protective factor for edema in the first 10 days postpartum (RR 0.64 95%CI 0.41-0.99) and involuntary gas loss at 45 days postpartum (RR0.57 95%CI 0.38-0.86). The residual adjustment ≥ 2 observed in the analysis of perineal conditions postpartum showed a trend of women in the intervention group having an intact perineum. The women and companions who performed perineal massage accepted the practice well, recommended it and would do it again in a future pregnancy. Conclusion The digital perineal massage performed daily from 34 weeks of gestation was a practice well accepted by women of this study and their companions. Although not protecting women from perineal trauma, this practice reduced the risk of edema at 10 days postpartum and gas incontinence at 45 days postpartum.

Methods This is applied research of technological development, consisting of the construction of an algorithm, assessment by professionals with expertise in the area, creation of a Decision Support System prototype using online tools and assessment of its applicability and accuracy during care for 305 childbirths performed by nurses. Data were analyzed using descriptive statistics, chi-square and Fisher's exact tests, in addition to the Kappa coefficient to assess the agreement between the procedure indicated by the system and that performed by professionals. Results There was agreement between the algorithm's suggestion and professional decision in 93.1% of childbirths. In 6.9%, professionals decided opposite paths to the recommended one. The professionals who chose to follow the algorithm's suggestion had perineal integrity or the occurrence of first-degree tear as an outcome. Those who chose not to follow the recommendation had second- or third-degree tears in 28.6% of parturient women. In the accuracy analysis, the algorithm suggested that episiotomy should be performed in 45 of the 305 assisted childbirths. There was an association between divergences in conduct and the number of adverse events (p=0.001). Conclusion The algorithm proved to be a useful tool for perineal assessment in childbirth care.

Important aspects during advanced lingual laceration management: report of 2 cases / Aspectos importantes para o manejo das lacerações complexas da língua: relato de 2 casos

ABSTRACT Intraoral injuries affect the stomatognathic system, creating difficulties in mastication and speech articulation, especially when they affect the tongue. In this context, the quality of the suture and local care are important to proper recovery and the patient's brief return to their normal functions. Oral lacerations resulting from trauma require specific approaches. Treatments of this type of trauma may primarily be performed by professionals who conduct emergency care; however, they may require the attention of specialists. This article contains recommendations for the primary approach, treatment, and postoperative care of complex lacerations in the tongue.

RESUMO As lesões intraorais afetam o sistema estomatognático, gerando dificuldades na mastigação e na articulação da fala, principalmente quando afetam a língua. Nesse contexto, a qualidade da sutura e o cuidado local são importantes para a recuperação adequada e o breve retorno do paciente às suas funções normais. As lacerações orais resultantes de trauma requerem abordagens específicas. Os tratamentos desse tipo de trauma podem ser realizados principalmente por profissionais que realizam atendimento de emergência; no entanto, eles podem exigir a atenção de especialistas. Este artigo contém recomendações para a abordagem primária, tratamento e cuidados pós-operatórios de lacerações complexas da língua.

Management of pediatric canalicular lacerations with the RS-1 silicone tube and the conventional silicone tube / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To evaluate the clinical effecacy of the RS-1 silicone tube and the conventional silicone tube in the management of pediatric canalicular lacerations.<p>METHODS: We retrospectively reviewed the medical records of 48 pediatric patients(48 eyes)with canalicular lacerations admitted for primary repair in the Department of Ocular Trauma of Hebei Eye Hospital from January 2015 to June 2018. The patients were divided into two groups according to the treatment of method: Group A(25 patients, the conventional silicone tube), Group B(23 patients, the RS-1 silicone tube). The management of pediatric canalicular lacerations were performed under general anesthesia. The silicone tube was removed about 3mo after surgery. The surgical time, clinical efficacy and complications were compared.<p>RESULTS: The mean surgical time between the two groups was 44.92±14.45min in Group A and 31.78±7.40min in Group B, which was statistically significant difference(<i>t</i>=4.02, <i>P</i><0.01). The clinical efficacy of the two groups was compared. Group A: 20 patients were cured(80%), 2 patients were improved(8%), 3 patients were failed(12%), and the functional success rate was 88%. Group B: 19 patients were cured(82%), 2 patients were improved(9%), 2 patients were failed(9%), the functional success rate was 91%, which was not statistically significant difference(χ2=0.14, <i>P</i>>0.05). The incidence of complications(32% <i>vs</i> 9%)including lower lacrimal point and mild eyelid eversion(1 patient 4% <i>vs</i> 1 patient 4%), slit canaliculus(2 patients 8% <i>vs</i> 1 patient 4%), early tube extrusion(3 patients 12% <i>vs</i> 0%), and nasal mucosal injury(3 patients 12% <i>vs</i> 0%)in Groups A and B, respectively, were comparable. There was statistically significant difference in the incidence of complications between the groups(χ2=3.94, <i>P</i><0.05).<p>CONCLUSION: There is no statistically significant difference with the two different types of silicone tube, which have good clinical efficacy, in the management of pediatric canalicular lacerations. But the RS-1 silicone tube is easier to operate, shorter surgical time, less complications and easier to removed.

Arrow Ocular Injury

@#Pediatric ocular trauma; though the number is small, can lead to a devastating lifetime impact due to its risk of amblyopia (if it occurs before the age of seven) and also loss of vision. We are reporting a case of a young 12-year-old-boy who was struck unintentionally by an arrow to the eye by another friend during sports activity. The arrow pierced the right eyebrow just below the orbital roof then perforated the globe from the superior orbit pointing downwards piercing the floor of the orbit fracturing the maxillary roof. Emergency scleral repair was done; however, there was no useful vision left. Arrow injury to the eye is a rare occurrence but leads to severe consequences given its high velocity and projectile in nature. The incidence is low and highly avoidable if precautionary measures are taken.

Factors related to perineal outcome after vaginal delivery in primiparas: a cross-sectional study / Factores relacionados con el resultado perineal tras parto vaginal en primíparas: estudio transversal / Fatores relacionados ao desfecho perineal após parto vaginal em primíparas: estudo transversal

Abstract Objective: Identify the associations between perineal outcome in primiparas and interventions during labor and delivery, newborn weight and APGAR score. Method: Document-based, correlational, retrospective, quantitative study conducted in a tertiary maternity hospital in the state of Ceará, between July 2017 and January 2018. The independent variables were labor induction, amniotomy, non-pharmaceutical methods for relieving pain, forceps, episiotomy, Kristeller maneuver, position in the expulsion stage, shoulder dystocia, and newborn weight and APGAR score, and the dependent variable was perineal outcome. Pearson's chi-square test and Fisher's exact test were used. Results: A total of 226 normal-risk primiparas who had a vaginal delivery. An association was found between horizontal position in the expulsion stage and episiotomy, and between not performing an episiotomy and perineal tearing. The other variables (labor, delivery and neonatal) did not have any effect on perineal tearing. Conclusion: Interventions, with the exception of episiotomies, did not have an influence on the occurrence of perineal trauma, but they do need to be carefully assessed. Deliveries in a horizontal position were associated with a higher likelihood of performing an episiotomy.

Resumen Objetivo: Identificar las asociaciones entre el resultado perineal en primíparas y las intervenciones ocurridas durante el trabajo de parto, parto, peso y APGAR del recién nacido. Método: Estudio documental, correlacional, retrospectivo, cuantitativo, llevado a cabo en una maternidad terciaria en el estado de Ceará, entre julio de 2017 y enero de 2018. Las variables independientes fueron inducción del parto, amniotomía, métodos no farmacológicos de alivio del dolor, fórceps, episiotomía, maniobra de Kristeller, posición en el período expulsivo, distocia de hombro, peso y APGAR del recién nacido, y la variable dependiente fue el resultado perineal. Se emplearon las pruebas de Chi cuadrado de Pearson y la exacta de Fisher. Resultados: Participaron 226 primíparas de riesgo habitual que parieron por vía vaginal. Se verificó asociación entre la posición horizontal en el período expulsivo del parto y episiotomía, y entre la no realización de episiotomía y laceración perineal. La otras variables de trabajo de parto, parto y neonatal no interfirieron en la ocurrencia de laceración perineal. Conclusión: Acciones intervencionistas, salvo la episiotomía, no influenciaron la ocurrencia de trauma perineal, sin embargo requieren evaluación juiciosa. El parto en la posición horizontal se relacionó con la mayor posibilidad de realización de episiotomía.

Resumo Objetivo: Identificar as associações entre o desfecho perineal em primíparas e as intervenções ocorridas durante o trabalho de parto, parto, peso e APGAR do recém-nascido. Método: Estudo documental, correlacional, retrospectivo, quantitativo, realizado em uma maternidade terciária no estado do Ceará, entre julho de 2017 e janeiro de 2018. As variáveis independentes foram indução do parto, amniotomia, métodos não farmacológicos de alívio da dor, fórceps, episiotomia, manobra de Kristeller, posição no período expulsivo, distocia de ombro, peso e APGAR do recém-nascido, e a variável dependente foi o desfecho perineal. Foram utilizados o teste de Qui-quadrado de Pearson e o teste exato de Fisher. Resultados: Participaram 226 primíparas de risco habitual que pariram por via vaginal. Verificou-se associação entre posição horizontal no período expulsivo do parto e episiotomia, e entre a não realização de episiotomia e laceração perineal. As outras variáveis de trabalho de parto, parto e neonatal não interferiram na ocorrência de laceração perineal. Conclusão: Ações intervencionistas, com exceção da episiotomia, não influenciaram a ocorrência de trauma perineal, porém requerem avaliação criteriosa. O parto na posição horizontal relacionou-se a maior probabilidade de realização de episiotomia.
