RESUMO
Objetivo: Reportar los hallazgos anatomopatológicos de las apendicectomías profilácticas en el Hospital Clínico de la Fuerza Aérea de Chile (FACh) y compararlos con los estudios reportados en la literatura. Material y Método: Análisis retrospectivo, descriptivo de los pacientes sometidos a apendicectomía laparoscópica profiláctica entre los años 2013 y 2017 en el Hospital FACh, y sus resultados anatomopatológicos de la pieza operatoria, según registro clínico y reportes de laboratorio patológico. Resultados: Se rescataron un total de 200 muestras de pacientes sometidos a apendicectomía. El 80% resultó sin hallazgos patológicos, mientras que 13,5% obliteración fibrosa, y 2,5% en apendicitis aguda en distinta etapa. Se evidenció una muestra de 0,5% de neoplasia maligna. Discusión: El porcentaje de apéndices no patológicos obtenidos se correlaciona con resultados expuestos en la literatura sobre apendicectomías incidentales. Por su parte, los hallazgos de malignidad están presentes en todos los reportes revisados, con una tasa relativa baja variable. Existe el debate si todos los apéndices deben ser estudiados. Conclusiones: No existen estudios similares al presente, sin embargo, es comparable a los reportes de apendicectomía incidental. Pareciera ser indispensable el estudio histopatológico por el riesgo de prevalencia de malignidad.
Objective: To report anatomopathological results of the prophylactic appendectomies in the Hospital Clínico de la Fuerza Aérea de Chile (FACh) and to compare them with existing studies. Material and Method: Descriptive, retrospective analysis of patients that underwent prophylactic appendectomies between 2013 and 2017 in the Hospital FACh and their anatomopathological results, according to clinical registries and pathology reports. Results: A total of 200 samples obtained from patients that underwent appendectomy were rescued. 80% resulted with no pathological findings, 13,5% had fibrous obliteration, and 2,5% showed acute appendicitis in different stages. Malignancy was found in 0,5% of the samples. Discussion: The percentage of non-pathological appendices correlates with the results reported in the literature. On the other hand, malignancy is present in all the reviewed reports, with a variable low relative rate. There is a debate on whether all appendixes should be studied. Conclusion: There are no studies like this one, however, our results are comparable to the reports of incidental appendectomies. Histopathological analysis seems to be essential due to the risk of prevalence of malignancy.

La preparación del boxeador conlleva cambios y adaptaciones fisiológicas para garantizar las cargas físicas, psíquicas y sociales a las que han sido sometidos sus practicantes. Finalizada dicha etapa aparece el desentrenamiento deportivo, cuya naturaleza es eminentemente pedagógica y consiste en desinstalar los componentes que garantizaron la acumulación de cargas durante su etapa como boxeador activo, hasta alcanzar los niveles de un practicante sistemático normal de la Cultura Física. El objetivo de este trabajo consistió en diseñar una estrategia pedagógica sustentada en un modelo de igual naturaleza para el desentrenamiento potenciado con la equino-interacción-profiláctica, a partir del uso de ejercicios con caballos como elemento de cambio. Se utilizaron como métodos empíricos y técnicas la observación de las sesiones de deportivo, el análisis de documentos, la encuesta a exboxeadores, entrenadores, médicos deportivos, funcionarios y expertos seleccionados, así como los talleres de opinión crítica y socialización entre entrenadores de boxeo. Como resultados se obtuvo un modelo pedagógico del que se derivó una estrategia. Estos aportes fueron constatados mediante la aplicación parcial de la estrategia en un combinado deportivo en Majibacoa, Las Tunas y se demostró su factibilidad para ser generalizada. El artículo que se ofrece tiene como objetivo socializar resultados de la investigación realizada sobre el desentrenamiento deportivo en el boxeo potenciado con el equino-interacción-profiláctica. De manera conclusiva, los aportes teórico y práctico demostraron el cumplimiento del objetivo de la investigación y la solución del problema científico.
A preparação do boxeador implica em mudanças e adaptações fisiológicas para garantir as cargas físicas, psicológicas e sociais às quais o boxeador foi submetido. Ao final dessa etapa, surge o destreinamento esportivo, cuja natureza é eminentemente pedagógica e consiste em desinstalar os componentes que garantiram o acúmulo de cargas durante sua etapa como boxeador ativo, até atingir os níveis de um praticante normal sistemático de Cultura Física. O objetivo deste trabalho consistiu em projetar uma estratégia pedagógica baseada em um modelo semelhante de destreinamento aprimorado com a interação equino-profilática, baseada no uso de exercícios com cavalos como elemento de mudança. Os métodos e técnicas empíricos utilizados foram a observação de sessões esportivas, a análise de documentos, pesquisas com ex-pugilistas, treinadores, médicos esportivos, oficiais e especialistas selecionados, bem como workshops de opinião crítica e socialização entre treinadores de boxe. Como resultado, foi obtido um modelo pedagógico do qual derivou uma estratégia. Essas contribuições foram confirmadas por meio da aplicação parcial da estratégia em uma equipe esportiva em Majibacoa, Las Tunas, e sua viabilidade de generalização foi demonstrada. O objetivo deste artigo é socializar os resultados da pesquisa realizada sobre o destreinamento esportivo no boxe, aprimorado com a interação equino-profilática. Em conclusão, as contribuições teóricas e práticas demonstraram o cumprimento do objetivo da pesquisa e a solução do problema científico.
The preparation of the boxer entails physiological changes and adaptations to guarantee the physical, psychological and social loads to which its practitioners have been subjected. Once this stage is completed, sports detraining appears, the nature of which is eminently pedagogical and consists of uninstalling the components that guaranteed the accumulation of loads during his time as an active boxer, until reaching the levels of a normal systematic practitioner of Physical Culture. The objective of this work was to design a pedagogical strategy based on a model of the same nature for detraining enhanced with equine-interaction-prophylactics, based on the use of exercises with horses as an element of change. Observation of sports sessions, document analysis, a survey of former boxers, coaches, sports doctors, officials and selected experts, as well as critical opinion and socialization workshops among boxing coaches, were used as empirical methods and techniques. As results, a pedagogical model was obtained from which a strategy was derived. These contributions were verified through the partial application of the strategy in a sports complex in Majibacoa, Las Tunas and its feasibility to be generalized was demonstrated. The article offered aims to socialize results of the research carried out on sports detraining in boxing enhanced with equine-interaction-prophylaxis. Conclusively, the theoretical and practical contributions demonstrated the fulfillment of the research objective and the solution of the scientific problem.
RESUMO
Cytomegalovirus(CMV)pneumonia is one of the common complications of hematopoietic stem cell transplantation,and is also a significant cause leading to patient death.Due to the poor prognosis of CMV pneumo-nia,intervention measures are necessary to prevent CMV reactivation and progress to CMV pneumonia.At present,clinical medication mainly relies on preemptive treatment strategies,and the timing of medication depends on the timeliness of early diagnosis.However,feasible methodology and measures for the early diagnosis of CMV pneumo-nia in clinical practice are relatively limited.Meanwhile the diagnostic gold standard operation is invasive,causing trauma to a certain degree,and the detection timeliness is poor.This review summarizes the clinical status and ad-vances in the diagnosis and drug prophylactic treatment of CMV pneumonia after hematopoietic stem cell transplan-tation,and explores possible development directions and trends in the future.
RESUMO
Objective:To analyze the treatment efficacy, safety and dose parameters of optimized hippocampus-avoidance prophylactic cranial irradiation (HA-PCI) in limited-stage small cell lung cancer (LS-SCLC) and explore the corresponding dosimetric parameters under the condition of narrowing the hippocampus avoidance region as hippocampus region plus 2 mm in three dimensions.Methods:Clinical data of patients with LS-SCLC receiving HA-PCI (hippocampus avoidance region defined as hippocampus region plus 2 mm in three dimensions) in Cancer Hospital Chinese Academy of Medical Sciences from August 2014 to June 2020 were retrospectively analyzed. Dose parameters of HA-PCI and adverse events were analyzed using descriptive statistics analysis. Changes of neurocognitive function, such as mini-mental state examination (MMSE) and Hopkins verbal learning test-revised (HVLT-R) scores, were evaluated by analysis of variance and Kruskal-Wallis H test. Overall survival (OS), progression-free survival (PFS) and intracranial PFS (iPFS) were calculated using Kaplan-Meier method. The cumulative incidence of local-regional recurrence (LRR), extracranial distant metastases (EDM), and locoregional recurrence (LR) were investigated under competing risk analysis. Results:A total of 112 patients were included, the median follow-up time was 50 months (95% CI: 45.61-54.38). The median volume of hippocampus was 4.85 ml (range: 2.65-8.34 ml), with the average dose ≤9 Gy in 106 patients (94.6%), ≤8 Gy in 92 patients (82.1%). The median volume of hippocampus avoidance area was 15.00 ml (range: 8.61-28.06 ml), with the average dose ≤12 Gy in 109 patients (97.3%), ≤10 Gy in 101 patients (90.2%). The 2-year cumulative LRR, EDM, LR rates were 16.9%, 23.2% and 28.5%, respectively. The 5-year cumulative LRR, EDM, LR rates were 23.2%, 26.9% and 33.3%, respectively. The 2-year iPFS, PFS and OS rates were 66.1% (95% CI: 57.9%-75.4%), 53.6% (95% CI: 45.1%-63.7%) and 80.4% (95% CI: 73.3%-88.1%), respectively. The most common grade I-Ⅱ adverse events were nausea (33.9%) and dizziness (31.3%), and only 1 patient developed grade Ⅲ nausea and dizziness. MMSE ( n=57) and HVLT-R tests ( n=56) showed no significant decline. Conclusions:Optimized HA-PCI can achieve similar dose limitation with favorable efficacy and light toxicity. No significant decline is observed in short-term neurocognitive function in evaluable patients.
RESUMO
Objective:To evaluate the feasibility of abandoning prophylactic abdominal drainage in patients undergoing minimally invasive minor hepatectomy based on a propensity score matching (PSM) study.Methods:Retrospective review of a prospectively collected database of patients undergoing minimally invasive minor hepatectomy from July 2022 to May 2023 at the Department of Hepatopancreatobiliary Surgery and Minimally Invasive Surgery, Zhejiang Provincial People's Hospital. A total of 108 patients were enrolled, including 48 males and 60 females, aged (60.8±13.7) years old. According to whether the abdominal drainage tube was prophylactically placed intraoperatively, patients were divided into two groups: the drainage group (with prophylactic placement of abdominal drainage tubes, n=76); the no-drainage group (without prophylactic placement of abdominal drainage tubes, n=32). PSM was used to compare the perioperative data between the groups, including extent of liver resection, intraoperative blood loss, operative time, and postoperative complications. Postoperative survival status within 90 days was followed up through telephone review. Results:Before PSM, the two groups differed significantly on age and the history of hypertension (both P<0.05). After PSM, there were 23 patients in each group. Patients in the two groups showed comparable results regarding the intraoperative parameters including the surgical method, pathological types, the number and maxium diameter of hepatic lesions, the extent and complexity of liver resection, and the duration of hepatic inflow occlusion (all P>0.05). No postoperative intra-abdominal bleeding occurred in either group. The incidences of postoperative complications were comparable between the groups, including fever, bile leakage, incision infection, and abdominal acupuncture for drainage (all P>0.05). After PSM, compared to patients wothout prophylactic abdominal drainage, prophylactic abdominal drainage group showed a decreased white blood cell counts on postoperative day 1 [9.39(6.30, 10.58)×10 12/L vs. 13.19(10.15, 14.90)×10 12 /L, P=0.006] and a shorter length of postoperative hospital stay [4(3, 5) d vs. 5(4, 5) d, P=0.033]. No postoperative death within 90 days occurred in either group. Conclusion:In minimally invasive minor hepatectomy, abandoning prophylactic abdominal drainage could be feasible, which facilitates fast recovery without increasing the incidence of postoperative fever, perihepatic fluid accumulation and postoperative abdominal acupuncture for drainage.

RESUMO
Abstract The increase in life expectancy of the world population has led to a concomitant increase in the prevalence of multiple myeloma (MM), a disease that usually affects the elderly population. Bone lesions are frequent in patients with this condition, demanding an early approach, from drug treatment, through radiotherapy to orthopedic surgery (prophylactic or therapeutic) with the objective of preventing or delaying the occurrence of fracture, or, when this event has already occurred, treat it through stabilization or replacement (lesions located in the appendicular skeleton) and/or promote stabilization and spinal cord decompression (lesions located in the axial skeleton), providing rapid pain relief, return to ambulation and resocialization, returning quality of life to patients. The aim of this review isto update the reader on the findings of pathophysiology, clinical, laboratory and imaging, differential diagnosis and therapeutic approach of multiple myeloma multiple myeloma bone disease (MMBD).
Resumo O aumento da expectativa devida da população mundial levou a incremento concomitante na prevalência de mieloma múltiplo (MM), patologia que geralmente afeta a população idosa. Lesões ósseas são frequentes nos portadores desta condição, demandando abordagem precoce, desde o tratamento medicamentoso, passando pela radioterapia até a cirurgia ortopédica (profilática ou terapêutica) com os objetivos de prevenir ou retardar a ocorrência de fratura, ou, quando este evento já ocorreu, tratá-la mediante estabilização ou substituição (lesões situadas no esqueleto apendicular) e/ou promover estabilização e descompressão medular (lesões situadas no esqueleto axial), proporcionando rápido alívio da dor, retorno à deambulação e ressocialização, devolvendo a qualidade de vida aos pacientes. O objetivo desta revisão é atualizar o leitor sobre a fisiopatologia, a clínica, exames laboratoriais e de imagem, diagnóstico diferencial e abordagem terapêutica da doença óssea no mieloma múltiplo (DOMM).

Objective To explore the value of prophylactic anticoagulation in the 28-day prognosis of patients with severe COVID-19.Methods The clinical data of COVID-19 patients admitted to Guangdong Provincial People's Hospital from December 2022 to January 2023 were collected,including age,gender,past medical history,routine blood test,liver and renal function,procalcitonin,coagulation function,Padua prediction score,antiviral therapy,hormonotherapy,immunotherapy and anticoagulation therapy.The patients were divided into an anticoagula-tion group and a non-anticoagulation group.The differences in various indicators were compared between the two groups.Cox regression was performed to assess the independent risk factors for 28-day mortality and the anticoagula-tion efficacy between the subgroups.Results Among 158 patients,128 received anticoagulation;There were significant differences between the two groups in case number of hypertension and critical condition,lymphocyte count,prothrombin time,D-dimer,and case number of immunotherapy.COX logistic regression showed that antico-agulation(HR = 2.25,95%CI:1.01～5.01,P = 0.048)was an independent risk factor for all-cause mortality of COVID-19 patients within 28 days.Subgroup analysis showed that anticoagulation therapy led to an increase in the 28-day mortality as level of procalcitonin of≥0.5 pg/mL(HR = 2.72,95%CI:1.05～7.04)or D-dimer of<2 000 ng/mL(HR = 9.16,95%CI:1.63～51.48).Conclusions Prophylactic anticoagulation did not reduce all-cause mortality of COVID-19 within 28 days.
RESUMO
Objective:To study the clinical characteristics, diagnostic methods and genotypes of neonatal chronic granulomatous disease(CGD).Methods:From April 2013 to August 2020, neonates admitted to our hospital, diagnosed with neonatal CGD and confirmed using neutrophil respiratory burst test and genetic testing were retrospectively studied. Their clinical characteristics and diagnostic methods were summarized.Results:A total of eleven neonates with CGD were enrolled, including ten males and one female. The age of onset was 3-23 d and the age of admission was 11-28 d. 3 cases had family history. The initial symptoms were fever (10 cases) and coughing (1 case). The accompanying symptoms included coughing (6 cases), dyspnea (4 cases), skin pustules (3 cases), fever (1 case) and diarrhea (1 case). Lung CT showed patchy shadows (6 cases), pulmonary nodules (3 cases), round and irregular high-density shadow (1 case), pulmonary consolidation (1 case), pleural effusion (1 case) and pleural thickening (2 cases). CGD was pathologically diagnosed in one patient. Sputum culture showed Candida albicans (3 cases), Aspergillus fumigatum (2 cases), Aspergillus fumigatum combined with Klebsiella pneumoniae and Escherichia coli (1 case), Aspergillus fumigatum combined with Staphylococcus aureus (1 case). GM tests were positive in two cases and negative in other two cases. Blood and cerebrospinal fluid cultures were negative. White blood cell counts were (10.0-44.0)×10 9/L and C-reactive proteins were (14-165) mg/L. 11 cases had positive neutrophil respiratory burst test. Genetic tests showed CYBB gene mutations (9 cases) , NCF1 gene mutation(1 case) and NCF2 gene mutation (1 case). All cases received antibacterial and antifungal treatments for 2-5 weeks and were discharged with improvement. 8 patients survived, 5 received hematopoietic stem cell transplantation, 4 succeeded and one failed and continued to survive on oral medication. 3 cases took sulfamethoxazole, voriconazole or itraconazole orally for long periods. 3 cases died of severe infections after withdrawal of medication. Conclusions:Neonatal CGD is characterized by lung infections. Pulmonary CT shows mostly nodular or patchy shadows with occasional pulmonary consolidation or pleural effusion. It can be diagnosed by neutrophil respiratory burst test and genetic testing. X-linked CYBB gene mutations are common and autosomal recessive NCF1/NCF2 gene mutations less common.
RESUMO
@#Migraine is a common neurological disorder，with a significantly higher prevalence rate in women than in men，and more than half of female patients have headache attacks associated with menstruation.Migraine in women is closely associated with the changes in hormones during the menstrual cycle，and the effect of “estrogen withdrawal” might be one of the possible mechanisms.Changes in hormones may play an important role in the development of migraine.Understanding the relationship between changes in each life stage and physiological cycle of women and headache may help to develop individualized treatment strategies，thereby improving the symptoms and prognosis of patients.
RESUMO
The link between sphincter of Oddi function with biliary system (gallbladder and bile duct) diseases is considered to be very complicated. Whether routine prophylactic laparos-copic cholecystectomy should be carried out after endoscopic sphincterotomy to remove bile duct stones has been controversial worldwide. Actually, this is a very common and important clinical question which needs to be answered. The author spends a lot of time and efforts to broadly read and analyze on published articles related to this topic, and tries, from the aspects of the anatomy and function of sphincter of Oddi, the biliary diseases causing by dysfunction or discordance of sphincter of Oddi, and the impacting of artificial destruction of sphincter of Oddi on the gallbladder and bile duct of patients, to come up with an answer to this question based on scientific and medical evidence.
RESUMO
Objective:To investigate the predictive value of enhanced CT-based radiomics for brain metastasis (BM) and selective use of prophylactic cranial irradiation (PCI) in limited-stage small cell lung cancer (LS-SCLC).Methods:Clinical data of 97 patients diagnosed with LS-SCLC confirmed by pathological and imaging examination in Shanxi Provincial Cancer Hospital from January 2012 to December 2018 were retrospectively analyzed. The least absolute shrinkage and selection operator (LASSO) Cox and Spearman correlation tests were used to select the radiomics features significantly associated with the incidence of BM and calculate the radiomics score. The calibration curve, the area under the receiver operating characteristic (ROC) curve (AUC), 5-fold cross-validation, decision curve analysis (DCA), and integrated Brier score (IBS) were employed to evaluate the predictive power and clinical benefits of the radiomics score. Kaplan-Meier method and log-rank test were adopted to draw survival curves and assess differences between two groups.Results:A total of 1272 radiomics features were extracted from enhanced CT. After the LASSO Cox regression and Spearman correlation tests, 8 radiomics features associated with the incidence of BM were used to calculate the radiomics score. The AUCs of radiomics scores to predict 1-year and 2-year BM were 0.845 (95% CI=0.746-0.943) and 0.878 (95% CI=0.774-0.983), respectively. The 5-fold cross validation, calibration curve, DCA and IBS also demonstrated that the radiomics model yielded good predictive performance and net clinical benefit. Patients were divided into the high-risk and low-risk cohorts based on the radiomics score. For patients at high risk, the 1-year and 2-year cumulative incidence rates of BM were 0% and 18.2% in the PCI group, and 61.8% and 75.4% in the non-PCI group, respectively ( P<0.001). In the PCI group, the 1-year and 2-year overall survival rates were 92.9% and 78.6%, and 85.3% and 36.8% in the non-PCI group, respectively ( P=0.023). For patients at low risk, the 1-year and 2-year cumulative incidence rates of BM were 0% and 0% in the PCI group, and 10.0% and 20.2% in the non-PCI group, respectively ( P=0.062). In the PCI group, the 1-year and 2-year overall survival rates were 100% and 77.0%, and 96.7% and 79.3% in the non-PCI group, respectively ( P=0.670). Conclusion:The radiomics model based on enhanced CT images yields excellent performance for predicting BM and individualized PCI.
RESUMO
Objective:To investigate the role of prophylactic cranial irradiation (PCI) in non-small cell lung cancer (NSCLC) by meta-analysis.Methods:Studies published from January 1, 1980 to August 30, 2021 were searched systematically in PubMed, Embase, Cochrane Systematic Review database and China National Knowledge Infrastructure Database. The searching keywords included "non-small cell lung cancer", "randomized controlled trial", "prophylactic cranial irradiation" and "clinical trial". The data extracted from the above studies were analyzed using Review Manager 5.3 and Stata 12.0 software. Outcomes included the development of brain metastases (BM), overall survival (OS), disease-free survival (DFS), toxicity, and quality of life (QoL).Results:Ten trials, including 2005 NSCLC patients, met the inclusion criteria. Patients who underwent PCI had a significantly lower risk of BM than those who did not ( OR=0.29, 95% CI: 0.22-0.40, P<0.001). Compared with non-PCI group, DFS in PCI group was significantly increased ( HR=0.75, 95% CI: 0.63-0.89, P=0.001). However, there was no significant difference in OS ( OR=0.90, 95% CI: 0.69-1.18, P=0.45). In addition, the incidence of fatigue was significantly increased in the PCI group ( OR=2.64, 95% CI: 1.58-4.40, P<0.001). There was no significant difference in cognitive impairment between the PCI and non-PCI groups ( OR=3.60, 95% CI: 0.97-13.32, P=0.06). Conclusions:PCI is the standard treatment for NSCLC. Compared with non-PCI, PCI significantly reduces the incidence of BM and prolongs the DFS of NSCLC patients. The effect of PCI-related toxicity on the QoL and long-term OS needs further study.
RESUMO
Objective:To analyze the prognosis and risk factors for brain metastases (BM) in patients with limited-stage small cell lung cancer (LS-SCLC) after complete resection, aiming to identify those most likely to benefit from prophylactic cranial irradiation (PCI).Methods:Clinical data of 94 patients with LS-SCLC treated in Cangzhou Integrated Traditional Chinese and Western Medicine Hospital from January 2005 to December 2018 who underwent complete resection were retrospectively analyzed, including 31 cases treated with PCI and 63 without PCI. Prognostic factors and risk factors of BM were analyzed by Kaplan-Meier method. The differences between two groups were analyzed by log-rank test. Independent risk factors of overall survival (OS) and BM were assessed by multivariate Cox regression model.Results:The 2-year and 5-year OS rates were 80.6% and 61.3% in the PCI group, and 61.9% and 46.0% in the non-PCI group, respectively ( P=0.001). The 2-year and 5-year brain metastasis-free survival (BMFS) rates were 80.6% and 54.8% in the PCI group, and 57.1% and 42.9% in the non-PCI group, respectively ( P=0.045). The 2-year and 5-year progression-free survival (PFS) rates were 71.0% and 48.4% in the PCI group, and 49.2% and 34.9% in the non-PCI group, respectively ( P=0.016). PCI could improve OS in patients with pII/III stage LS-SCLC ( P=0.039, P=0.013), but the OS benefit in patients with pI stage LS-SCLC was not significant ( P=0.167). BM occurred in 3 patients (9.7%) in the PCI group, which was significantly lower than that in the non-PCI group ( n=17, 27.0%; P=0.044); there was no significant difference in the BM rate of patients with pI and pII stage LS-SCLC between PCI and non-PCI groups ( P=0.285, P=0.468); and the BM rate of patients with pIII stage LS-SCLC in the PCI group was significantly lower than that in the non-PCI group ( P=0.041). Multivariate analysis showed age ≥60 ( HR=2.803, P=0.001), BM ( HR=2.239, P=0.022), no PCI ( HR=0.341, P=0.004) and pathological stage pII/III ( HR=4.963, P=0.002) were the independent high-risk factors affecting OS; and pathological stage pII/III ( HR=11.665, P=0.007) was an independent high-risk factor affecting BM. Conclusions:LS-SCLC patients with pII-III stage have a higher risk of developing BM and poor prognosis after complete resection, and should receive PCI treatment. However, LS-SCLC patients with pI stage may not benefit significantly.
RESUMO
Objective: To investigate the genetic, clinical and pathological characteristics of families with hereditary breast-ovarian cancer syndrome (HBOCS) and to explore the implementation of genetic counseling and preventive surgery. Methods: Four siblings with HBOCS in Cancer Hospital/Chinese Academy of Medical Sciences were selected as the study subjects. BRCA gene testing and genetic counseling were performed, family history was traced and family map was drawn. Results: There were 7 cancer patients (Ⅰ 2, Ⅱ 4, Ⅱ 8, Ⅲ 7, Ⅲ 10, Ⅲ 11, Ⅲ 12) in three generations in the family. One patient (Ⅲ 7) had breast cancer and ovarian cancer successively. The first generation (Ⅰ 2) developed cancer at age 60, the second generation (Ⅱ4 and Ⅱ8) developed cancer at 55. The third generation (Ⅲ 7, Ⅲ 10, Ⅲ 11, Ⅲ 12) developed cancer at the age of 42-50 years. Four HBOCS patients were treated in our hospital, and all of them were found to have deleterious BRCA1 mutation. Two had already developed ovarian cancer (Ⅲ 10, Ⅲ 12), while in one case (Ⅲ 11), tubal carcinoma was found during preventive total hysterectomy and pelvic lymph node metastasis was found after the supplementary staging surgery. The other patient without cancer underwent preventive bilateral salpingectomy(Ⅲ 15). Conclusion: The HBOCS family reported in this study is relatively rare, the onset time of tumor was younger generation by generation. It is very important to pay attention to the genetic counseling of ovarian cancer patients and to timely detect the HBOCS families for genetic testing and prophylactic surgery.

@#BACKGROUND: It is controversial whether prophylactic endotracheal intubation (PEI) protects the airway before endoscopy in critically ill patients with upper gastrointestinal bleeding (UGIB). The study aimed to explore the predictive value of PEI for cardiopulmonary outcomes and identify high-risk patients with UGIB undergoing endoscopy. METHODS: Patients undergoing endoscopy for UGIB were retrospectively enrolled in the eICU Collaborative Research Database (eICU-CRD). The composite cardiopulmonary outcomes included aspiration, pneumonia, pulmonary edema, shock or hypotension, cardiac arrest, myocardial infarction, and arrhythmia. The incidence of cardiopulmonary outcomes within 48 h after endoscopy was compared between the PEI and non-PEI groups. Logistic regression analyses and propensity score matching analyses were performed to estimate effects of PEI on cardiopulmonary outcomes. Moreover, restricted cubic spline plots were used to assess for any threshold effects in the association between baseline variables and risk of cardiopulmonary outcomes (yes/no) in the PEI group. RESULTS: A total of 946 patients were divided into the PEI group (108/946, 11.4%) and the non-PEI group (838/946, 88.6%). After propensity score matching, the PEI group (n=50) had a higher incidence of cardiopulmonary outcomes (58.0% vs. 30.3%, P=0.001). PEI was a risk factor for cardiopulmonary outcomes after adjusting for confounders (odds ratio [OR] 3.176, 95% confidence interval [95% CI] 1.567-6.438, P=0.001). The subgroup analysis indicated the similar results. A shock index >0.77 was a predictor for cardiopulmonary outcomes in patients undergoing PEI (P=0.015). The probability of cardiopulmonary outcomes in the PEI group depended on the Charlson Comorbidity Index (OR 1.465, 95% CI 1.079-1.989, P=0.014) and shock index >0.77 (compared with shock index ≤0.77 [OR 2.981, 95% CI 1.186-7.492, P=0.020, AUC=0.764]). CONCLUSION: PEI may be associated with cardiopulmonary outcomes in elderly and critically ill patients with UGIB undergoing endoscopy. Furthermore, a shock index greater than 0.77 could be used as a predictor of a worse prognosis in patients undergoing PEI.
RESUMO
Background - Migraine is one of the common causes of recurrent headaches. Botulinum toxin type A (Botox®) is a neurotoxin produced by Clostridium botulinum that paralyzes nerves. The purpose of this study was to evaluate the efficacy of pericranial Botox® administration in migraine headache in patients attending a tertiary eye care centre. Method - A prospective, non-randomized study consisting of 54 patients was performed. Subjects were candidates who either sought Botox® treatment for hyperfunctional facial lines with concomitant headache or candidates for Botox® treatment specifically for headaches. Headaches were classified based on International Headache Society criteria. Botox® was injected into the glabellar, temporal, frontal, and/or suboccipital regions of the head and neck. Patients were treated every three months, with a maximum of three sessions. Botox dosage ranged from 75 - 155 Units per patient. Main outcome measures were relief from migraine headache symptoms, reduction of headache severity and duration of symptom free period. Age ranged from 18 to 65 (mean 34.6±6.5) years. Among 54 subjects treatedResults - prophylactically, complete response (symptom elimination) was noted in 31 (57.40%) with a mean {Standard deviation – (SD)} response duration of 4.3 (2.4) months; 16 (29.62%) reported partial response (?50% reduction in headache frequency or severity) with a mean (SD) response duration of 2.5 (1.7) months. 7 (12.96%) reported no response. No systemic adverse effects were reported. Botox® is found to be a safe and effective therapy for prophylacticConclusion - treatment of migraine.
RESUMO
RESUMEN La mastectomía reductora de riesgo, también conocida como mastectomía profiláctica, consiste en extirpar la mayor cantidad de tejido posible de una mama sana para reducir el riesgo potencial de desarrollar cáncer. Se presenta el caso de una paciente de 30 años de edad, de color de piel negra, multípara y con antecedentes de padecer desde muy joven enfermedad macroquística de mamas. A esta paciente se le había realizado mastectomía subcutánea bilateral 10 años atrás a causa de enfermedad macroquística y que no tuvo posibilidad de implantes en esa ocasión, lo que le acarreó cicatrices inestéticas y secuelas psicológicas. La paciente acudió al Servicio de Cirugía Plástica del Princess Marina Hospital de Botswana en África solicitando corrección estética. Con la intervención se logró una mama armónica, aunque pequeña, con tejidos autólogos, sin complicaciones mayores y con la perspectiva para aumento de volumen mamario futuro con tejidos autólogos. En esta paciente la reconstrucción estética fue una opción necesaria y a su vez efectiva dado su contexto socioeconómico. Se presenta el caso por lo interesante que resulta este tipo de intervención realizada por especialistas cubanos en su colaboración médica en un país africano.
ABSTRACT Risk-reducing mastectomy, also known as prophylactic mastectomy, involves removing as much tissue as possible from a healthy breast to reduce the potential risk of developing cancer. A case of a 30-years-old, black-skinned, multiparous patient with a history of suffering from a very young macrocystic breast disease is presented. This patient had undergone bilateral subcutaneous mastectomy 10 years ago due to macrocystic disease and had no possibility of implants on that occasion, which caused unaesthetic scars and psychological sequelae. The patient went to the Plastic Surgery Service of the Botswana Prince Marina Hospital in Africa requesting aesthetic correction. With the intervention, a harmonic breast was achieved, although small, with autologous tissues, without major complications and with the prospect of future breast volume increase with autologous tissues. In this patient, aesthetic reconstruction was a necessary and effective option given her socioeconomic context. The case is presented due to the interesting nature of this type of intervention carried out by Cuban specialists in their medical collaboration in an African country.
