Frequency of the prominent transverse nasal root vein in children.

Background: The presence of a vascular, blue linear discoloration on the nasal root of infants and young children is a frequent incidental feature, rarely reported in the medical literature. It is related to the trajectory of the transverse nasal root vein (TNRV).

Objective: To study the frequency and clinical characteristics of the vascular discoloration of the nasal root in children.

Calcified Pilocytic Astrocytomas and Calcifying Pseudoneoplasms of the Neuraxis: A Diagnostic Challenge.

Pilocytic astrocytoma (PA), recognized as the most prevalent central nervous system (CNS) tumor, has long been associated with calcifications, a characteristic often attributed to benign or indolent growth patterns. In this study, we explored the calcified attributes in these tumors that beckon a deeper understanding. This is a retrospective study, on a set of seven cases, with a histopathological diagnosis of pilocytic astrocytoma with calcifications and psammoma bodies (PB).

Genitourinary symptoms and sexual function in women with primary ovarian insufficiency.

Objective: There are limited studies on urogenital symptoms in women who experience menopause before the age of 40 years due to primary ovarian insufficiency (POI) or bilateral oophorectomy (surgical POI). This study aimed to compare the urogenital symptoms, including sexuality, of women with POI to those without the condition.

Methods: This cross-sectional study conducted was in seven Latin American countries, in which postmenopausal women (with POI and non-POI) were surveyed with a general questionnaire, the Menopause Rating Scale (MRS) and the six-item Female Sexual Function Index (FSFI-6).

Variant-specific pathophysiological mechanisms of AFF3 differently influence transcriptome profiles.

Background: We previously described the KINSSHIP syndrome, an autosomal dominant disorder associated with intellectual disability (ID), mesomelic dysplasia and horseshoe kidney,caused by variants in the degron of AFF3. Mouse knock-ins and overexpression in zebrafish provided evidence for a dominant-negative (DN) mode-of-action, wherein an increased level of AFF3 resulted in pathological effects.

Methods: Evolutionary constraints suggest that other mode-of-inheritance could be at play.

Multi-Institutional Outcomes of Dorsal Onlay Buccal Mucosal Graft Urethroplasty in Patients With Postprostatectomy, Postradiation Anastomotic Stenosis.

Purpose: The treatment of urethral stenosis after a combination of prostatectomy and radiation therapy for prostate cancer is understudied. We evaluate the clinical and patient-related outcomes after dorsal onlay buccal mucosal graft urethroplasty (D-BMGU) in men who underwent prostatectomy and radiation therapy.

Materials And Methods: A multi-institutional, retrospective review of men with vesicourethral anastomotic stenosis or bulbomembranous urethral stricture disease after radical prostatectomy and radiation therapy from 8 institutions between 2013 to 2021 was performed.

Gallbladder Agenesis: Must General Surgeons Have It on Their Diagnostic Algorithm?

Gallbladder agenesis is a rare congenital malformation that can present itself with comparable symptoms as any case of cholelithiasis. We present a case of a 76-year-old male patient without any medical background of significance who presented at the ER complaining of sudden abdominal pain that started two hours prior to his arrival. Laboratory tests were ordered and an increase in total bilirubin was noted, showing a cholestatic pattern.

Metabolic and Bariatric Surgery in Patients with Obesity Class V (BMI > 60 kg/m): a Modified Delphi Study.

Background: Metabolic and bariatric surgery (MBS) is the preferred method to achieve significant weight loss in patients with Obesity Class V (BMI > 60 kg/m). However, there is no consensus regarding the best procedure(s) for this population. Additionally, these patients will likely have a higher risk of complications and mortality.

Pathology results of endoscopic ultrasound-guided tissue acquisition in retroperitoneal masses: a multicenter study.

Background: Malignant etiologies are found in 70-80% of symptomatic retroperitoneal masses. Histology is required for diagnosis and treatment. Information about endoscopic ultrasound (EUS)-guided tissue acquisition (EUS-GTA) is scant for retroperitoneal masses.

Latin American formal consensus on the indications for the surgical treatment of massive and irreparable rotator cuff tears.

Objectives: To implement the Formal Consensus Method among a group of experts in shoulder surgery in Latin America, in order to establish appropriate indications for the surgical treatment of massive and irreparable rotator cuff injuries.

Methods: The Formal Consensus Method was used to develop surgical treatment recommendations for massive and irreparable rotator cuff tears (MIRCT). Three independent groups of experts in shoulder surgery were confirmed.

Counseling in menopausal women: How to address the benefits and risks of menopause hormone therapy. A FIGO position paper.

Menopause marks the end of menstrual cyclicity and, depending on individual vulnerability, has several consequences related to gonadal steroid deprivation, especially if it is premature. Menopause may be more burdensome for some women than for others. Individual factors, such as personal history, socioeconomic status, ethnicity, and current health conditions, affect symptomatology and, thereby, the menopausal experience.

Cardiac Biomarkers Aid in Differentiation of Kawasaki Disease from Multisystem Inflammatory Syndrome in Children Associated with COVID-19.

Kawasaki disease (KD) and Multisystem Inflammatory Syndrome in Children (MIS-C) associated with COVID-19 show clinical overlap and both lack definitive diagnostic testing, making differentiation challenging. We sought to determine how cardiac biomarkers might differentiate KD from MIS-C. The International Kawasaki Disease Registry enrolled contemporaneous KD and MIS-C pediatric patients from 42 sites from January 2020 through June 2022.

Association of SARS-CoV-2 infection with neurological impairments in pediatric population: A systematic review.

Neurological manifestations have been widely reported in adults with COVID-19, yet the extent of involvement among the pediatric population is currently poorly characterized. The objective of our systematic review is to evaluate the association of SARS-CoV-2 infection with neurological symptoms and neuroimaging manifestations in the pediatric population. A literature search of Cochrane Library; EBSCO CINAHL; Global Index Medicus; OVID AMED, Embase, Medline, PsychINFO; and Scopus was conducted in accordance with the Peer Review of Electronic Search Strategies form (October 1, 2019 to March 15, 2022).

Spinal Ependymomas: An Updated WHO Classification and a Narrative Review.

Ependymomas are neuroepithelial tumors that develop from ependymal cells found in the brain parenchyma and can spread to any part of the spinal cord. Three to six percent of all malignancies affecting the central nervous system (CNS) are ependymomas. Even the most talented surgeons are challenged by spinal cord ependymomas; as a result, research into this clinical phenomenon should continue.

[Robot-assisted radical prostatectomy with Retzius-Sparing approach vs. modified Frankfurt: comparison of results at 1 year of follow-up].

Background: Robot-assisted radical prostatectomy has positioned itself as the approach of choice in the treatment of prostate cancer.

Objective: To compare the outcomes of robot-assisted radical prostatectomy using the Retzius-Sparing (RS) approach against the modified Frankfurt (MF) technique.

Method: To describe the perioperative, functional and oncological outcomes of 13 patients with prostate cancer who underwent RS robotic radical prostatectomy compared to MF, evaluating pathological results, urinary continence, sexual function and oncological control in 1 year of follow-up.

Single-row or Double-row Rotator Cuff Repair.

Rotator cuff tears are potentially a career-ending injury for athletes. The surgeon must identify which patients will benefit from surgical repair. The factors to consider are age, type of sport, time since injury, athlete's level, and the patient's expectations.

The Mexican consensus on fecal incontinence.

Fecal incontinence is the involuntary passage or the incapacity to control the release of fecal matter through the anus. It is a condition that significantly impairs quality of life in those that suffer from it, given that it affects body image, self-esteem, and interferes with everyday activities, in turn, favoring social isolation. There are no guidelines or consensus in Mexico on the topic, and so the Asociación Mexicana de Gastroenterología brought together a multidisciplinary group (gastroenterologists, neurogastroenterologists, and surgeons) to carry out the «Mexican consensus on fecal incontinence» and establish useful recommendations for the medical community.

Hepatitis C virus-positive donors in HCV-negative recipients in liver transplantation: Is it possible in Mexico?

Hepatitis C virus (HCV) infection is a worldwide public health problem associated with significant morbidity and mortality. In the context of liver transplantation, the demand for organs continues to exceed the supply, prompting the consideration of using organs from HCV-positive donors in HCV-negative recipients. The introduction of direct-acting antivirals (DAAs), which have demonstrated great efficacy in eradicating the virus, has made transplantation of organs from donors with HCV infection possible.

All-Arthroscopic Management of Locked Posterior Shoulder Dislocation: Reduction Under Direct Visualization and Treatment of Intra-articular Pathologies.

Locked posterior shoulder dislocation (LPSD) is a rare condition often overlooked. In most cases, the humeral head remains stuck behind the glenoid, causing an impression fracture in 40% to 90% of LPSD cases, known as a reverse Hill-Sachs lesion. The condition also affects the posterior capsulolabral complex and leads to the formation of scar tissue under the coracoid and subscapularis tendon, making it challenging to reduce without surgery.

Comparison of microvascular decompression, percutaneous radiofrequency rhizotomy, and stereotactic radiosurgery in the treatment of trigeminal neuralgia: A long term quasi-experimental study.

Background: Microvascular decompression (MVD), radiofrequency rhizotomy (RFR), and stereotactic radiosurgery (SRS) are surgical techniques frequently used in the treatment of idiopathic trigeminal neuralgia (TN), although the results reported for each of these are diverse.

Objective: This study aimed to compare long-term pain control obtained by MVD, SRS, and RFR in patients with idiopathic TN.

Methods: To compare the results obtained by MVD, SRS, and RFR we chose a quasi-experimental, ambispective design with control groups but no pretest.

A cross-sectional study on the prevalence of cardiovascular disease in elderly patients with long-term type 2 diabetes mellitus mainly attended in private clinics in Mexico. The CAPTURE study.

Background: To estimate the contemporary prevalence of established cardiovascular disease (CVD) in adults with type 2 diabetes (T2D) in Mexico.

Methods: CAPTURE was a multinational, non-interventional, cross-sectional study across 13 countries from five continents. Standardized demographic and clinical data were collected from adults with T2D attending a single routine healthcare visit in primary or specialized care between December 2018 and September 2019.

[Results of all-inside arthroscopic meniscal sutures, mid-term review].

Introduction: all-in meniscal suture devices have evolved and simplified meniscal repair. In this study we will formulate the following research questions: what is the rate of survival and failure? What are the risk factors associated with failure? And what are the functional results after meniscal repair surgery?

Material And Methods: ambispective study from 2001 to 2021 of patients with repairable meniscal injury with all-in meniscal suture devices. The survival and failure ratio were obtained with the Kaplan-Meier test, the risk factors associated with meniscal suture failure were assessed with the logistic regression test, and the pre- and post-surgical functional results were estimated with the test.

Gain-of-function and loss-of-function variants in GRIA3 lead to distinct neurodevelopmental phenotypes.

AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid) receptors (AMPARs) mediate fast excitatory neurotransmission in the brain. AMPARs form by homo- or heteromeric assembly of subunits encoded by the GRIA1-GRIA4 genes, of which only GRIA3 is X-chromosomal. Increasing numbers of GRIA3 missense variants are reported in patients with neurodevelopmental disorders (NDD), but only a few have been examined functionally.
