Growing teratoma syndrome: diagnostic challenges and outcomes.

PURPOSE: The aim of this case report is to emphasize the significance of the growing teratoma syndrome. Growing teratoma syndrome is frequently misdiagnosed due to its low prevalence, with an estimated incidence of 19% among all immature ovarian teratomas and a lack of experience among healthcare professionals. It is characterized by the growth of benign tumoral tissue during or after chemotherapy for malignant germ cell tumors. CASE REPORT: Our case is about a 46-year-old patient diagnosed with an immature teratoma who was treated unsuccessfully with surgery and chemotherapy. The patient was then referred to our hospital for a second opinion, where this unknown entity was diagnosed and underwent complete surgical debulking, including abdominal wall resection and subsequent repair. CONCLUSION: Physicians need to be aware of rapidly growing masses during or after chemotherapy because early recognition of this syndrome is essential for the adequate treatment of our patients.

Utility of indocyanine green as a single tracer for sentinel node biopsy in endometrial cancer.

AIM: Our study aims to investigate the safety and effectiveness of sentinel lymph node biopsy using indocyanine green (ICG) for the surgical staging of early-stage endometrial cancer in comparison to technetium-99 m use. METHODS: We conducted an observational retrospective study with patients diagnosed of endometrial cancer and FIGO stages I-II. All participants were injected technetium-99m the day prior to the surgery and underwent lymphoscintigraphy along with single-photon emission computed tomography. In addition, all patients were administered intraoperatively ICG injection to detect sentinel lymph node biopsy. The surgical staging was then completed according to the European Society for Medical Oncology preoperative risk category. Data obtained from the analysis of technetium-99m detection was compared to ICG detection. RESULTS: A total of 53 women with endometrial cancer were included in the study, 49 (92.5%) of them showed drainage preoperatively in the single-photon emission computed tomography and/or lymphoscintigraphy. The intraoperative bilateral detection rate for technetium-99 m was 26 (49.1%) patients compared to 40 (75.5%) patients with ICG (p = 0.013). We observed a 42.5% increase in the mean number of lymph nodes retrieved by ICG compared to technetium-99m (2.85 vs 2,0 nodes; p = 0.002). We intraoperatively identified 164 lymph nodes, 104 (63.4%) located in both obturator areas and external iliac vessels. CONCLUSION: The use of ICG for the performance of sentinel node biopsy in patients with endometrial cancer seems safe and could be superior to technetium-99 m, since it offers a higher bilateral detection rate and nodal retrieval, resulting in the possibility to perform safely less full staging lymphadenectomies.

Direct trocar insertion without previous pneumoperitoneum versus insertion after insufflation with Veress needle in laparoscopic gynecological surgery: a prospective cohort study.

The aim of this study was to determine whether direct trocar entry without prior pneumoperitoneum at umbilical level (DTI) can be a safe alternative to access the abdominal cavity in gynaecological laparoscopic surgery. We present a prospective observational analytical study of cohorts, comparing DTI with umbilical entry with trocar after previous insufflation with a Veress needle at umbilical level (V). The study period was performed from June 2013 to April 2016; data was collected on 600 patients who underwent gynaecological laparoscopic surgery. There were no significant differences in the risk of suffering a complication during the access manoeuvres between DTI (6.49%) and V (7.39%), OR 0.89 (95% CI: 0.42-1.81). The duration of the access manoeuvres was 69 s in DTI and 193 s in V (p < .001). The percentage of patients in whom two or more access attempts were performed was lower in DTI (7.8%) than in V (12.3%) (p > .05). We concluded that DTI is at least as safe as V, regarding the risk of suffering complications arising from access into the abdominal cavity. DTI has advantages with regard to V, such as: the shorter duration of access manoeuvres or the lesser number of unsuccessful entry or insufflation attempts. Impact statement What is already known on this subject? There are few international publications comparing DTI and V. When we conducted a search in PubMed for the terms 'Veress needle and direct trocar insertion', 51 publications were obtained. When we increased the restriction and added the terms 'laparoscopic entry and laparoscopy complications', 27 publications were obtained; thus, the uniqueness of our study. What do the results of this study add? We present a 3-year observational prospective study of cohorts that included 600 patients. The aim of this study was to determine that in laparoscopic gynaecological surgery, DTI is an access method to the abdominal cavity at least as safe as V, with respect to the risk of complications. On the other hand, DTI has some advantages such as the shorter duration of access manoeuvres or the lower number of failed entry attempts. What are the implications of these findings for clinical practice and/or further research? Given the limited number of publications that compared both techniques, our study indicates that DTI can be a safe alternative for access to abdominal cavity in gynaecological surgery, compared to the traditional V.

Safety and patients' satisfaction after hysteroscopic sterilisation.

The aim of this study was to understand the potential complications of the Essure® device as well as the factors influencing its onset and patient satisfaction. We present a 9-year descriptive prospective study that included 1068 patients. The device was placed in 1056 of them (98.8%); 894 had no pain or mild pain during the insertion and only 12 patients experienced pain greater than menstrual pain. The proportion of patients without pain was greater in the group that took NSAIDs or NSAIDs and BZD and the unmedicated group had the highest rate of severe pain (p = .00). In all, 161 of the 1064 patients who had the Essure® inserted reported having an adverse effect during the 3-months post-insertion (pelvic pain or discomfort). The mean score out of 10 attributed to this method was 9.06 (S = 1.11). We concluded that the Essure® shows a low rate of complications and users showed a high degree of satisfaction. Impact statement What is already known on this subject: There are few international publications on Essure®. When we conducted a search in PubMed for the term 'Essure', we obtained 221 publications. When we added the terms 'Essure and complications', we obtained 20 publications, and when we increased the restriction including 'satisfaction', we obtained seven; thus, the uniqueness of our study. What the results of this study add: We present a 9-year descriptive prospective study that included 1068 patients. The aim of this study was to understand the potential complications of the Essure® device (Bayer, Whippany, NJ), as well as factors that can influence its onset and the patient satisfaction. The device was placed in 1056 of the patients (98.8%); 894 had no pain or mild pain during the insertion and only 12 patients experienced pain greater than menstrual pain. The proportion of patients without pain was greater in the group that took NSAIDs or NSAIDs and BZD and the unmedicated group had the highest rate of severe pain (p=.00). What the implications are of these findings for clinical practice and/or further research: Our study shows a low rate of complications with Essure®, mild and transient in most cases, as well as a high degree satisfaction. Nevertheless, given the few published studies on this device, we believe that long-term follow-up is needed.

Parametrization of halogen bonds in the CHARMM general force field: Improved treatment of ligand-protein interactions.

A halogen bond is a highly directional, non-covalent interaction between a halogen atom and another electronegative atom. It arises due to the formation of a small region of positive electrostatic potential opposite the covalent bond to the halogen, called the 'sigma hole.' Empirical force fields in which the electrostatic interactions are represented by atom-centered point charges cannot capture this effect because halogen atoms usually carry a negative charge and therefore interact unfavorably with other electronegative atoms. A strategy to overcome this problem is to attach a positively charged virtual particle to the halogen. In this work, we extend the additive CHARMM General Force Field (CGenFF) to include such interactions in model systems of phenyl-X, with X being Cl, Br or I including di- and trihalogenated species. The charges, Lennard-Jones parameters, and halogen-virtual particle distances were optimized to reproduce the orientation dependence of quantum mechanical interaction energies with water, acetone, and N-methylacetamide as well as experimental pure liquid properties and relative hydration free energies with respect to benzene. The resulting parameters were validated in molecular dynamics simulations on small-molecule crystals and on solvated protein-ligand complexes containing halogenated compounds. The inclusion of positive virtual sites leads to better agreement across experimental observables, including preservation of ligand binding poses as a direct result of the improved representation of halogen bonding.

[Definitive contraception with Essure device: Single institutional experience on 517 procedures]. / Anticoncepción definitiva con Essure: experiencia unicéntrica de 517 procedimientos.

OBJECTIVES: To analyse the outcomes of patients undergoing Essure sterilization in a single institution, interns of complications and technique failure. PATIENTS AND METHODS: Retrospective descriptive study of 517 patients underwent definitive contraception with Essure device in outpatient hysteroscopy office without anesthesia and controlled at 3 months with abdominal radiography, ultrasonography and hysterosalpingography in selected cases. RESULTS: The success rates of the insertion of Essure was 96.8%, similar to data reported in the literature with 3.7% of vagal reactions, as most prevalent complication. 7 (1.35%) unintended pregnancies were observed. CONCLUSIONS: Essure is a permanent birth control device, with high rate of successful insertion and a low rate of complications. Unintended pregnancies in our study are high and we must change the protocols of placement and monitoring, considering hysterosalpingography as a routine control test.

Surgeons vs ChatGPT: Assessment and Feedback Performance Based on Real Surgical Scenarios.

INTRODUCTION: Artificial intelligence tools are being progressively integrated into medicine and surgical education. Large language models, such as ChatGPT, could provide relevant feedback aimed at improving surgical skills. The purpose of this study is to assess ChatGPT´s ability to provide feedback based on surgical scenarios. METHODS: Surgical situations were transformed into texts using a neutral narrative. Texts were evaluated by ChatGPT 4.0 and 3 surgeons (A, B, C) after a brief instruction was delivered: identify errors and provide feedback accordingly. Surgical residents were provided with each of the situations and feedback obtained during the first stage, as written by each surgeon and ChatGPT, and were asked to assess the utility of feedback (FCUR) and its quality (FQ). As control measurement, an Education-Expert (EE) and a Clinical-Expert (CE) were asked to assess FCUR and FQ. RESULTS: Regarding residents' evaluations, 96.43% of times, outputs provided by ChatGPT were considered useful, comparable to what surgeons' B and C obtained. Assessing FQ, ChatGPT and all surgeons received similar scores. Regarding EE's assessment, ChatGPT obtained a significantly higher FQ score when compared to surgeons A and B (p = 0.019; p = 0.033) with a median score of 8 vs. 7 and 7.5, respectively; and no difference respect surgeon C (score of 8; p = 0.2). Regarding CE´s assessment, surgeon B obtained the highest FQ score while ChatGPT received scores comparable to that of surgeons A and C. When participants were asked to identify the source of the feedback, residents, CE, and EE perceived ChatGPT's outputs as human-provided in 33.9%, 28.5%, and 14.3% of cases, respectively. CONCLUSION: When given brief written surgical situations, ChatGPT was able to identify errors with a detection rate comparable to that of experienced surgeons and to generate feedback that was considered useful for skill improvement in a surgical context performing as well as surgical instructors across assessments made by general surgery residents, an experienced surgeon, and a nonsurgeon feedback expert.

Multivalent binding of the tardigrade Dsup protein to chromatin promotes yeast survival and longevity upon exposure to oxidative damage.

Tardigrades are remarkable in their ability to survive extreme environments. The damage suppressor (Dsup) protein is thought responsible for their extreme resistance to reactive oxygen species (ROS) generated by irradiation. Here we show that expression of Ramazzottius varieornatus Dsup in Saccharomyces cerevisiae reduces oxidative DNA damage and extends the lifespan of budding yeast exposed to chronic oxidative genotoxicity. This protection from ROS requires either the Dsup HMGN-like domain or sequences C-terminal to same. Dsup associates with no apparent bias across the yeast genome, using multiple modes of nucleosome binding; the HMGN-like region interacts with both the H2A/H2B acidic patch and H3/H4 histone tails, while the C-terminal region binds DNA. These findings give precedent for engineering an organism by physically shielding its genome to promote survival and longevity in the face of oxidative damage.

Modelling the risk of hospital admission of lab confirmed SARS-CoV-2-infected patients in primary care: a population-based study.

The objectives of this study are to develop a predictive model of hospital admission for COVID-19 to help in the activation of emergency services, early referrals from primary care, and the improvement of clinical decision-making in emergency room services. The method is the retrospective cohort study of 49,750 patients with microbiological confirmation of SARS-CoV-2 infection. The sample was randomly divided into two subsamples, for the purposes of derivation and validation of the prediction rule (60% and 40%, respectively). Data collected for this study included sociodemographic data, baseline comorbidities, baseline treatments, and other background data. Multilevel analyses with generalized estimated equations were used to develop the predictive model. Male sex and the gradual effect of age were the main risk factors for hospital admission. Regarding baseline comorbidities, coagulopathies, cancer, cardiovascular diseases, diabetes with organ damage, and liver disease were among the five most notable. Flu vaccination was a risk factor for hospital admission. Drugs that increased risk were chronic systemic steroids, immunosuppressants, angiotensin-converting enzyme inhibitors, and NSAIDs. The AUC of the risk score was 0.821 and 0.828 in the derivation and validation samples, respectively. Based on the risk score, five risk groups were derived with hospital admission ranging from 2.94 to 51.87%. In conclusion, we propose a classification system for people with COVID-19 with a higher risk of hospitalization, and indirectly with it a greater severity of the disease, easy to be completed both in primary care, as well as in emergency services and in hospital emergency room to help in clinical decision-making.Registration: ClinicalTrials.gov Identifier: NCT04463706.

[Node status in 454 ductal breast cancers cases according to the association with in situ component]. / Afectación ganglionar en 454 casos con carcinoma ductal infiltrante de mama según el hallazgo de componente intraductal asociado.

BACKGROUND: Studies have shown that breast infiltrating ductal carcinoma develops from precursor lesions or pre-invasive. It is accepted that the risk of invasive ductal carcinoma increased slightly in hyperplasia, but especially in cases of atypical hyperplasia and intraductal carcinoma. OBJECTIVES: To evaluate and compare the nodal status between ductal breast cancer with in situ component (group 1) or without it (group 2). MATERIAL AND METHOD: Descriptive and retrospective study that included 454 ductal breast cancers. Data concerning clinical and pathological variables was collected. All data was compared between both groups. RESULTS: Among all cases, 176 (38.8%) showed positive lymph nodes, 136 patients (39.5%) from group 1 and 40 cases (36.4%) from group 2. Among group 1 cases, high-grade subgroup showed higher positive lymph node rate (82 cases, 55.4%) than the extensive in situ carcinomas subgroup (84 cases, 49.7%). Both of them had a significant higher rate than group 2 cases (p = 0.003 y p = 0.028, respectively). Moreover, the low-grade in situ carcinomas without cellular necrosi had positive lymph nodes just in 30 cases (24%), significantly lower (p = 0.034) than group 2. CONCLUSIONS: We did not find overall statistical differences between groups depending on in situ associated component. But when we analyzed in situ subgroups, we found differences with higher positive lymph node rate in high grade carcinomas and extensive in situ carcinomas subgroups, while lower affectation rates were observed in low grade carcinomas (without cellular necrosis), compared to the group of breast cancers without in situ component associated.

[Low transmission of SARS-CoV-2 at school settings: a population-based study in the Basque Country.] / Baja transmisión del SARS-CoV-2 en el ámbito escolar: estudio poblacional en Euskadi.

OBJECTIVE: Studies about SARS-CoV-2 transmission at school settings have been outbreaks or schools clusters. There are scarce population-based studies has been studied. We aimed at describing SARS-CoV-2 school-related transmission and its relationship with baseline community cumulative incidence rate in the Basque Country after school reopening in order to inform Public Health decision-making. METHODS: We conducted a scholar surveillance population-based study of SARS-CoV-2 transmission from 7 September to 31 October 2020. We calculated percentages of cases in school-age population, secondary attack rates by education level among close contacts and correlation between population´s and scholars´ incidence rates at municipal level. RESULTS: There were 35,477 SARS-CoV-2 laboratory confirmed cases. Among them, 7.65% happened at school settings. Secondary attack rate at schools ranged from 2.9%, in preschools to 7.1% in high schools; Scholars caused a household and social secondary attack rate from 13% (high scholars) to 23.2% (elementary scholars). We found a low correlation between population´s and scholars´ incidence rates at municipal level (R2=0.047). CONCLUSIONS: Secondary attack rate at school settings increased as educational level did; conversely, to social and family secondary attack rate, that decreased with higher educational level. School attendance, during a SARS-CoV-2 high transmission period showed feasible and did not rise transmission. These findings happened under strict non-pharmaceutical measures at school settings and proper epidemiological surveillance, including tracing of laboratory confirmed cases of SARS-CoV-2 looking for close contacts, isolation and testing of close contacts during isolation period. The different degree of transmission of the circulating variants in the different periods of the pandemic must also be taken into account.

OBJETIVO: La transmisión del SARS-CoV-2 en escolares se ha estudiado en brotes o en conjuntos de escuelas y apenas hay estudios poblacionales. El objetivo de este estudio fue describir la transmisión de SARS-CoV-2 relacionada con el ámbito escolar y su relación con la incidencia acumulada comunitaria en Euskadi tras la reapertura de las escuelas para contribuir a la toma de decisiones en salud pública. METODOS: Se trató de un estudio poblacional, basado en el sistema de vigilancia epidemiológica, que analizó la transmisión de SARS-CoV-2 en el ámbito escolar tras la reapertura escolar el 7 de septiembre de 2020 hasta el 31 octubre de 2020. Se calcularon porcentajes de casos en población escolar, tasas de ataque secundaria por nivel educativo entre contactos estrechos, así como la correlación entre tasas de incidencia acumulada municipal y tasa en escolares. RESULTADOS: Se diagnosticaron 35.477 casos confirmados de SARS-CoV-2. Entre ellos el 7,65% sucedieron en el ámbito escolar. La tasa de ataque secundaria en dicho ámbito osciló entre un 2,9%, en educación infantil y un 7,1% en bachiller; los alumnos causaron, en el ámbito familiar y social, tasas de ataque secundarias de entre un 13% (bachiller) y un 23,2% (educación primaria). Encontramos una baja correlación entre las tasas de incidencia acumulada a nivel municipal y la de los escolares (R2=0,047). CONCLUSIONES: La tasa de ataque secundaria en ámbito escolar aumentó según el grado escolar, al contrario que la del ámbito social y familiar que disminuyó. La educación presencial no condujo a un incremento de la transmisión de SARS-CoV-2. Estos hallazgos sucedieron bajo estrictas medidas no farmacológicas en el ámbito escolar y una vigilancia epidemiológica adecuada que incluyó la búsqueda de contactos estrechos de casos de SARS-CoV-2 confirmados por laboratorio, así como el aislamiento y testeo de los contactos estrechos durante el periodo de aislamiento. Ha de tenerse en cuenta también, el diferente grado de transmisión de las variantes circulantes en los diferentes periodos de la pandemia.

Arthroscopic tuberoplasty for subacromial impingement secondary to proximal humeral malunion.

Subacromial impingement secondary to malunion of proximally displaced greater tuberosity fractures may be treated with arthroscopic acromioplasty in patients with slight displacements, but open anatomical repositioning of the malunited fragment is recommended when more severe deformities exist. This deformity may also be addressed by abrading the protruding proximal portion of the greater tuberosity (tuberoplasty). However, this procedure would require full elevation of the rotator cuff insertion if performed with open surgery. This article reports a technique of arthroscopic tuberoplasty based on combined intra- and extra-articular transtendinous abrasion of the proximal end of the greater tuberosity for malunions with severe upward displacement of the greater tuberosity. This procedure allows for major preservation of the rotator cuff insertion.

[Sonographic ovarian vascularization and volume in women with polycystic ovary syndrome treated with clomiphene citrate and metformin]. / Vascularización y volumen ovárico ecográfico en mujeres con síndrome de ovario poliquístico tratadas con citrato de clomifeno y metformina.

OBJECTIVE: To measure the vascularization and ovarian volume with three-dimensional sonography in patients diagnosed of polycystic ovary syndrome with stimulated ovulation treatment, and to analyse the differences between the patients treated with clomiphen citrate versus clomiphen citrate and metformin. MATERIAL AND METHOD: Therty patients were studied. Twenty ovulation cycles were obtained with clomiphen citrate and 17 with clomiphen citrate plus merformin (added in case of obesity or hyperglucemy/hyperinsulinemia). Ovarian volumes and vascular indexes were studied with 3D-sonography and results were analysed by treatment. RESULTS: There were no statistical differences of ovarian volume by treatment along the cycles, although bigger volume were found in ovulatory cycles compared to non-ovulatory ones (20,36 versus 13,89 ml, p = 0,026). No statistical differences were also found concerning vascular indexes, neither by treatment nor by the obtention of ovulation in the cycle. CONCLUSIONS: Ovarian volume and vascular indexes measured with three-dimensional sonography in patients diagnosed of polycystic ovary syndrome do not show differents values in patients treated with clomiphen citrate alone versus clomiphen citrate plus metformin.

[Diagnostic reliability of an asynchronous teledermatology consultation]. / Fiabilidad diagnóstica de una consulta de teledermatología asíncrona.

OBJECTIVE: To analyze the diagnostic agreement rate between primary care, an asynchronous teledermatology consultation, and a conventional dermatology consultation. DESIGN: Prospective non-randomized concordance study. SETTING: Dermatology Service in Hospital Son Llàtzer (Palma de Mallorca) and primary care centers of Sóller and Arenal (Mallorca). PARTICIPANTS: Patients have been included from December 2005 to July 2008, sent by teleconsultation (n=158). MAIN MEASUREMENTS: Analysis of primary care, teledermatology consultation and face-to-face consultation diagnosis, in mentioned period of time. Calculation of kappa index of concordance. RESULTS: 158 teleconsultations have been made from December 2005 to July 2008, 94 (59,5%) women, and 64 (40,5%) men, aged from 9 to 96 years old (average, 55 years old). After grouping the diagnosis in categories, the distribution was: 48 (37,2%) benign tumours, 39 (30,2%) inflammatory and appendages diseases, 15 (11,6%) infectious diseases, 14 (10,9%) malignant tumours, and 13 (10,1%) premalignant tumours. In grouped diagnosis, concordance was 59,8% (CI 95%, 50-70%) (P<.0001) for general practitioner and 94,7% (CI 95%, 90-99%) (P<.0001) for teledermatologist. CONCLUSIONS: The main advantage of asynchronous teledermatology is the improvement of the quality triage, allowing the detection of malignant or suspicious lesions. However, we need more comparable studies on a larger scale to evaluate the disadvantages (photographic technique limitation, evaluation of other lesions, legal aspects, professional motivation...).

[Reproducibility of the fetal nasal bone measurement by means of bidimensional and three-dimensional ecography during the second trimester of the pregnancy]. / Reproducibilidad de la medición del hueso nasal fetal mediante ecografía bidimensional y tridimensional durante el segundo trimestre del embarazo.

AIMS: The utility of the valuation-measurement of the nasal bone in the prognosis of chromosomopaties during the second trimester of the pregnancy is demonstrated. OBJECTIVE: To evaluate the repeatability of nasal bone measurement during second trimester with bidimensional and three-dimensional sonography. MATERIAL AND METHOD: Nasal bone was measured in 50 single pregnancies. First observer carried out two measures of nasal bone with bidimensional sonography, and 1 measure with three-dimensional sonography. Second observer carried out just one measure with bidimensional sonography (2D) and just another one with three-dimensional sonography (3D). We studied the intraobserver variability with 2D sonography, and the interobserver variability with 2D and 3D sonography. RESULTS: 2D-sonography: nasal bone measurement showed excellent intraobserver correlation with a correlation coefficient of 0,87 (CI 95%: 0,78-0,93) and a little means difference of 0,18 (SD: 0,74). Indeed, there was a good interobserver correlation with a correlation coefficient of 0,92 (CI 95%: 0,85-0,95), and a means difference of 0,14 (SD: 0,56). 3D-sonography: there was a acceptable interobserver correlation with correlation coefficient of 0,70 (CI 95%: 0,52-0,82). CONCLUSION: Nasal bone measurement is highly reproducible by means of bidimensional sonography while using three-dimensional sonography, the results are just acceptable.

[Urogenital prolapse repair using polypropylene mesh]. / Reparación del prolapso urogenital con malla de polipropileno.

BACKGROUND: Urogenital prolapse is a condition that affects 1 to 43% of post-hysterectomized patients. Since several years some synthetic meshes have been used to repair pelvic floor, and apparently they have advantages over them predecessors. OBJECTIVE: To evaluate the efficacy and security of polypropylene meshes in the repair of urogenital prolapse. MATERIAL AND METHOD: Retrospective and non-randomized study in 106 patients that had different kinds of urogenital prolapse repaired using polypropylene meshes. The follow-up was carried out by two visits to the hospital, 2 and 6 months after surgery. The variables analyzed were age, parity, menopause presence, kind of surgical technique, surgical time, time at hospital and complications. Afterwards, the information was analyzed descriptively. RESULTS: Average age was 64.4 years. The rate of multiparity and menopause women was 91.51% and 92.45% respectively. The most used surgical technique was the anterior mesh with tension-free band (34,90%) to repair the associated urinary incontinence. The rate of intraoperatory complications was 2.8%, immediate complications was 37.7% and late complications was 21.6%. The success rate after 6 months was 80 to 100%, depending on the technique. CONCLUSIONS: There is a low rate of intraoperatory and medium-term complications in the reconstructive surgery of pelvic floor for the urogenital prolapses using polypropylene meshes, which makes this technique a secure and effective option for the treatment of this problem.

Updates in the correlation of electroneuromyographic findings in diabetic polyneuropathy / Actualidades en la correlación de hallazgos electroneuromiográficos en polineuropatía diabética

Background: The diabetic neuropathy is the most common microvascular complication of diabetes mellitus. The reported prevalence ranges from 10-90%. Electrophysiological alterations can be demonstrated in nearly 100% of diabetics. Objective: To know the current profile of the patient with diabetic polyneuropathy. Methods: Retrospective and descriptive study from 2015 to 2016. Reports of electroneuromyography with diabetic polyneuropathy result were analyzed, evaluating neuroconduction parameters of motor and sensory nerves, late F responses and myography. Descriptive statistics, Student's t-test and Pearson's correlation coefficient were used. Results: The sample included 72 men (65.5%) and 38 women (34.5%), mean age 61.2 years, mean duration of diabetes of 9.9 years. The most affected nerve was superficial peroneus, absent in 70% of the population.A positive correlation was found (p < 0.001) for the affection of all the nerves symmetrically and predominantly in neuroconduction velocities of the lower and upper limbs. Conclusion: The most frequent electrophysiological finding in diabetic polyneuropathy was sensory affection, being more severe in lower limbs. A finding in patients with recent diagnosis is the prolongation of proximal latencies in the lower extremities.

Introducción: la neuropatía diabética es la complicación microvascular más frecuente de la diabetes mellitus. Las prevalencias reportadas oscilan del 10 al 90%. Se pueden demostrar alteraciones electrofisiológicas en casi el 100% de los diabéticos. Objetivo: conocer el perfil actual del paciente con polineuropatía diabética. Métodos: estudio retrospectivo y descriptivo del año 2015 a 2016. Se analizaron reportes de electroneuromiografía con resultado de polineuropatía diabética, evaluando parámetros de neuroconducción de nervios motores y sensoriales, respuestas tardías F y miografía. Se utilizó estadística descriptiva, la prueba de t de Student y el coeficiente de correlación de Pearson. Resultados: la muestra incluyó a 72 hombres (65.5%) y 38 mujeres (34.5%), con edad media de 61.2 años, todos con diagnóstico de diabetes mellitus tipo 2, con duración media de la diabetes de 9.9 años. El nervio más afectado fue el peroneo superficial, ausente en el 70% de la población. Se encontró una correlación positiva(p < 0.001) para la afección de todos los nervios de forma simétrica y de predominio en velocidades de neuroconducción de miembros inferiores y superiores. Conclusión: el hallazgo electrofisiológico más frecuente en polineuropatía diabética fue la afección sensorial, siendo más severa en miembros inferiores. Un hallazgo en pacientes con reciente diagnóstico es la prolongación de latencias proximales en extremidades inferiores.

Screening for Depressive Mood During Acute Chikungunya Infection in Primary Healthcare Settings.

Background: We aimed to screen for depressive mood experienced during acute chikungunya (CHIKV) infection, and to evaluate the association of several exposures with the risk of depressive symptoms. Methods: A cross-sectional analysis of a multicenter cohort study took place and data from 354 adult individuals with confirmed CHIKV infection were analyzed. Participants were recruited in primary health care settings and the Patient Health Questionnaire-2 (PHQ-2) was used. Prevalence odds ratios (OR) and 95% confidence intervals (CIs) estimated by means of logistic models were used. Results: Depressive mood (PHQ-2 score 3 or higher) was reported by 44.1% of individuals. Subjects with articular effusion (OR = 3.37, 95% CI 1.77⁻8.11), gastrointestinal manifestations (diarrhea, vomiting or abdominal pain, OR = 1.97, 95 CI 1.21⁻3.19), and higher length of severe arthralgia (reference ≤ 14 days: 15⁻30 days, OR = 3.38, 95% CI 1.78⁻6.41; ≥ 30 days, OR = 1.69, 95% CI 0.95⁻3.01) were more likely to self-report depressive mood. Increasing age (≥ 40 years old, OR = 0.55, 95% CI 0.31⁻0.95) and rash (OR = 0.54, 95% CI 0.30⁻0.98) were associated with a decreased risk of depressive mood. Conclusions: Depressive mood seemed to be a frequent event among analyzed individuals, and markers associated with its risk were identified.

[Fetal chylothorax. Is prenatal treatment beneficial?]. / Quilotórax fetal: es benéfico su tratamiento prenatal?

[Current situation on fertility preservation in cancer patients in Spain: Level of knowledge, information, and professional involvement]. / Situación de la preservación de fertilidad en pacientes con cáncer en nuestro medio: grado de conocimiento, información e implicación de los profesionales.

INTRODUCTION: The estimated risks of infertility in childhood cancer due to radiation, chemotherapy and surgery are well known. The involvement of professionals and advances in the different methods of preservation are increasing. However, many patients do not receive information or perform any method of preservation. MATERIAL: Questionnaires to paediatric onco-haematology institutions throughout Spain. The questionnaire consisted of 22 questions assessing their usual practices and knowledge about fertility preservation. RESULTS: Fifty members of the Spanish Society of Paediatric Haematology and Oncology, representing 24 of 43 centres, responded. These represented 82% of centres that treated higher numbers of patients. The effect of treatment on fertility was known by 78% of those who responded, with 76% admitting not knowing any guideline on fertility in children or adolescents. As for the ideal time and place to inform the patient and/or family, only 14% thought it should be done in the same cancer diagnosis interview. In clinical practice, 12% of those surveyed never referred patients to Human Reproduction Units, another 12% only did so if the patients showed interest, and 38% only refer patients in puberty. Just over one-third (34%) of those referrals were going to receive highly gonadotoxic treatment. CONCLUSIONS: There are clear differences between pre-puberty and puberty patients. The frequency with which some method of fertility preservation is performed in patients is low. All respondents believe that the existence of national guidelines on the matter would be of interest.
