Al considerar la importancia que en la práctica puede tener el infarto segmentario primario del epiplón mayor (lSPEM) en el diagnóstico diferencial de las entidades que producen abdomen agudo quirúrgico y teniendo en cuenta la información tan exigua que existe del mismo, cuyo desconocimiento obviamente influye en su baja frecuencia, hemos creído de interés publicar el caso que ha motivado la presente comunicación, el cual es el primero que se informa en la literatura médica nacional. Se refiere a un paciente de 26 años, arquitecto, que presentó el ISPEM 32 horas después de una nefrectomía ya quien en una segunda intervención se le practicó omentectomía. Luego falleció en un estado de insuficiencia respiratoria y shock.

Sexuality is a component of great relevance in humans. Sexual disorders are a major public health problem representing a high prevalence in the general population. DSM-5 genito-pelvic pain/penetration disorder (GPPPD) includes dyspareunia and vaginismus (DSM-IV-TR). To assess the importance of research on these disorders in Spain, we evaluated the Spanish scientific publications of primary and community care. The objective was to quantify the magnitude of the publications of GPPPD in Spanish women in primary and community care. For this, we used the method of conducting a systematic review and meta-analysis of studies evaluating GPPPD. As main results, of the 551 items found, we selected 11 studies that met the inclusion criteria. In primary care in Spain, one in nine women has these disorders; the percentage of women with GPPPD in this study (raw data) was 11.23% (95% CI: 0-29%) (vaginismus 5%; penetration pain 8.33%; dyspareunia 16.45%). These percentages can differ of those from other countries, and they are at the top of the data of the European countries (9-11.9%). There is much variability in the studies found in the world with respect to the prevalence of these health problems.

Background and Aims: Emergency General Surgery (EGS) conditions account for millions of deaths worldwide, yet it is practiced without benchmarking-based quality improvement programs. The aim of this observational, prospective, multicenter, nationwide study was to determine the best benchmark cutoff points in EGS, as a reference to guide improvement measures., Methods: Over a 6-month period, 38 centers (5% of all public hospitals) attending EGS patients on a 24-h, 7-days a week basis, enrolled consecutive patients requiring an emergent/urgent surgical procedure. Patients were stratified into cohorts of low (i.e., expected morbidity risk <33%), middle and high risk using the novel m-LUCENTUM calculator., Results: A total of 7258 patients were included; age (mean ± SD) was 51.1 ± 21.5 years, 43.2% were female. Benchmark cutoffs in the low-risk cohort (5639 patients, 77.7% of total) were: use of laparoscopy ≥40.9%, length of hospital stays ≤3 days, any complication within 30 days ≤ 17.7%, and 30-day mortality ≤1.1%. The variables with the greatest impact were septicemia on length of hospital stay (21 days; adjusted beta coefficient 16.8; 95% CI: 15.3 to 18.3; P < .001), and respiratory failure on mortality (risk-adjusted population attributable fraction 44.6%, 95% CI 29.6 to 59.6, P < .001). Use of laparoscopy (odds ratio 0.764, 95% CI 0.678 to 0.861; P < .001), and intraoperative blood loss (101-500 mL: odds ratio 2.699, 95% CI 2.152 to 3.380; P < .001; and 500-1000 mL: odds ratio 2.875, 95% CI 1.403 to 5.858; P = .013) were associated with increased morbidity., Conclusions: This study offers, for the first time, clinically-based benchmark values in EGS and identifies measures for improvement., (Copyright © 2021 IJS Publishing Group Ltd.

Background: To evaluate the retinal toxicity after repeated intravitreal injections of a humanized anti-VEGF-A monoclonal antibody (PRO-169) versus ranibizumab in New Zealand white (NZW) rabbit eyes., Methods: NZW rabbits were injected intravitreally with PRO-169 (n = 12), 1.25 mg/0.05 ml or ranibizumab (n = 12), 0.5 mg/0.05 ml into the right eye (OD), whereas the left eye (OS) of each rabbit was used as control. Three consecutive injections were administered at 30-days intervals. An electroretinogram (ERG) was recorded 30 days after each injection. Clinical examination was conducted before and after injections, including intraocular pressure determination and eye fundus exploration. Eyes were enucleated and retina, cornea, conjunctiva, ciliary body and optic nerve were prepared for histopathology assessment., Results: ERG of the experimental and control eyes in PRO-169 and ranibizumab groups were similar in amplitude and pattern throughout the follow-up period. Clinical examination found no alterations of intraocular pressure (IOP). No retinal damage was observed in both, the experimental and control eyes, of all the rabbits. The histopathologic studies showed similar results in both groups, showing no signs of structural damage., Conclusions: Our study did not find evidence of retinal toxicity from a repeated intravitreal injection of PRO-169 or ranibizumab (Lucentis ® ) in NZW rabbits. These findings support intravitreal PRO-169 as a safe candidate to develop as a future alternative for the treatment of retinal neovascularization diseases., Competing Interests: Competing interestsThe authors declare that they have no other competing interest in this work., (© The Author(s) 2020.)

Background: The principles of perineal reconstructive surgery comprise adequate filling of the defect along with stable and durable skin coverage, with a low morbidity rate. Two-flap perineal reconstruction is a simple, fast and reliable technique that uses a single donor site. This improves scar position with low morbidity. It is based in the use of 2flaps; one flap fills the defect with a «turn over» technique and the other is a rotation - advancement flap for skin coverage., Clinical Case: A 52-year-old male diagnosed with Lynch syndrome who underwent laparoscopic abdominoperineal amputation for adenocarcinoma of the lower rectum and developed recurrence 2years later over the perineal scar that required radical resection and perineal reconstruction., Conclusion: The use of this approach facilitates perineal reconstruction and enables treatment of patients with large and complex defects in frequently irradiated tissues where wound dehiscence and infection are common., (Copyright © 2017 Academia Mexicana de Cirugía A.C.
