Surgical management of iliac wing fractures: Proposal of a new classification system.

Introduction: Isolated fractures of the iliac wing are a rare injury, usually occurring in high-energy trauma, and are associated with other non-musculoskeletal and soft tissue injuries that could compromise the patient's life. Surgical indications are unclear, and there is limited information on the most frequent fracture patterns.

Methods: A descriptive multicenter case series study of isolated fractures of the iliac wing treated surgically in three referral trauma hospitals in Latin America.

[¿Anafilaxia perioperatoria? Serie de casos].

Objective: Identify the causative agent of POH, to avoid re-exposure and assess the use of alternative treatment.

Methods: 10 cases of immediate POH are described, in all of them a history of previous surgical procedures, carrying out a 3-step protocol: 1st documenting the surgical record to identify exposures, 2nd performing skin and/or epicutaneous tests and 3rd searching for an alternative treatment. treatment if a new surgical procedure is required and in selected cases challenge tests.

Image-guided radiation therapy (IGRT) in prostate cancer in México, survey of SOMERA (Sociedad Mexicana de Radioterapeutas/Mexican Society of Radiation Oncologists) with recommendations on its implementation and process.

Background: Prostate cancer is one of the main tumors worldwide, its treatment is multidisciplinary, includes radiotherapy in all stages: curative, radical, adjuvant, salvage and palliative. Technological advances in planning systems, image acquisition and treatment equipment have allowed the delivery of higher doses limiting toxicity in healthy tissues, distributing radiation optimally and ensuring reproducibility of conditions. Image-guided radiotherapy (IGRT) is not standard in guidelines, only recommended with heterogeneity in its own process.

[Guidelines on atopic dermatitis for Mexico (GUIDAMEX): using the ADAPTE methodology].

With the advancement of knowledge in relation to the physiopathogenesis of atopic dermatitis (AD), several new therapeutic forms have been developed. There are also new guidelines for self-care. On the other hand, there is still an underdiagnosis of AD in Mexico.

Risk factors for mortality of adult patients with COVID-19 hospitalised in an emerging country: a cohort study.

Objective: To describe mortality of in-hospital patients with COVID-19 and compare risk factors between survivors and non-survivors.

Design: Prospective cohort of adult inpatients.

Setting: Tertiary healthcare teaching hospital in Guadalajara, Mexico.

High frequency of HPV genotypes 59, 66, 52, 51, 39 and 56 in women from Western Mexico.

Background: Human papillomavirus infection is an important factor associated with cervical cancer (CC) development. The prevalence and genotype distribution vary greatly worldwide. Examining local epidemiological data constitutes an important step towards the development of vaccines to prevent CC.

Evaluation of the quality of life related to vision after penetrating keratoplasty.

Introduction: Organ and tissue donation and transplantation represent the most important therapeutic advance of current times. The cornea is, by far, one of the most transplanted tissues worldwide due to the immune privilege of this tissue, as well as the advances in microsurgery, existence of cornea banks, preservation of corneas, and use of anti-rejection therapy. However, many patients with successful corneal transplants (with clear corneas) experience poor vision in the post-operative period due to irregular astigmatism, or other complications.

[Anxiety in the presence of food in schoolchildren of Baja California Sur].

Introduction: many obese children will be obese adults unless they adopt and maintain healthy eating and physical activity patterns. Anxiety has been described in overweight and obese children with dysfunctional family environments, with impact on their quality of life; risk for some eating disorder was also found. Objective: to identify anxiety in the presence of food in schoolchildren in Baja California Sur.

The supernatant of cervical carcinoma cells lines induces a decrease in phosphorylation of STAT-1 and NF-κB transcription factors associated with changes in profiles of cytokines and growth factors in macrophages derived from U937 cells.

Macrophages are presents in the tumor microenvironment and acquire different phenotypic and functional characteristics in response to microenvironmental signals. Macrophages can be differentiated into two phenotypes: M1 or pro-inflammatory (classically activated), and M2 or anti-inflammatory macrophage (alternatively activated). In response to the microenvironment, macrophages activate transcription factors as STAT1 and NF-κB-p65 for M1 macrophages or STAT3 and STAT6 for M2 macrophages; activation impacts on the profile of cytokine, chemokines and growth factors secreted by macrophages.

Superficial siderosis misdiagnosed as idiopathic bilateral neurosensorial deafness.

Superficial siderosis (SS) is a rare condition resulting from different sources of bleeding into the subpial space. The most common symptoms are: hypoacusia, ataxia, incontinence, dementia and parkinsonism. Since several neurodegenerative disorders may present with same clinical features, SS is often misdiagnosed.

Ex Vivo Repair of a Renal Artery Saccular Aneurysm in a Living-Nonrelated Donor and Subsequent Successful Kidney Transplantation.

The use of kidney grafts with aneurysmal disease involving the renal arteries for transplantation is very uncommon and relatively controversial. We herein present the case of a 52-year-old woman who volunteered to become a living-nonrelated donor; during the preoperative imaging workup, a computed tomography angiography revealed a 1.5-cm saccular aneurysm in the left kidney, while the contralateral renal artery was normal.

Severe Craniofacial Involvement due to Amniotic Band Sequence.

Background: Disruptive amniotic band sequence (DABS) is a sporadic, non-familial disorder with unclear etiology. Diagnosis is based on clinical features because there is currently no reliable laboratory diagnostic tests.

Objective: We describe six cases of DABS with severe craniofacial deformations, three with and three without classical constrictive limb deformation.

[Gastric perforation by MALT lymphoma. Case report].

Background: Gastric non-Hodgkin lymphoma is a rare tumour that represents approximately 7% of all stomach cancers and 2% of all lymphomas. The most frequent location of gastric MALT (mucosa associated lymphoid tissue) lymphomas is in the antrum in 41% of the cases, and 33% can be multifocal. The risk of spontaneous perforation of a gastric MALT lymphoma is 4-10%.

Alpha 2HS-glycoprotein, a tumor-associated antigen (TAA) detected in Mexican patients with early-stage breast cancer.

Unlabelled: Several studies have demonstrated that the serum of patients with cancer contains antibodies that react with a group of autoantigens denominated tumor-associated antigens (TAA). TAA can be detected prior to clinical diagnosis; thus, they would be ideal biomarkers for early detection of cancer, using only a few microliters of a patient's serum. In the current study, we used an immune proteomic approach, combining two-dimensional (2D) electrophoresis, Western blot, and matrix-associated laser desorption/ionization-mass spectrometry (MALDI-MS) methods to identify TAA in the sera of patients diagnosed with breast cancer.

Oral allopurinol to prevent hyperamylasemia and acute pancreatitis after endoscopic retrograde cholangiopancreatography.

Aim: To assess the efficacy of allopurinol to prevent hyperamylasemia and pancreatitis after endoscopic retrograde cholangiopancreatography (PEP).

Methods: One hundred and seventy patients were enrolled and randomized to two groups: a study group (n = 85) who received 300 mg of oral allopurinol at 15 h and 3 h before endoscopic retrograde cholangiopancreatography (ERCP) and a control group (n = 85) receiving an oral placebo at the same times. Main Outcome Measurements included serum amylase levels and the number severity of the episodes of pancreatitis.

[Association between wound size after open cholecystectomy with severity of iatrogenic biliary tract lesions].

Background: Transoperative biliary tract injury during open or laparoscopic cholecystectomy is a catastrophic event associated with significant morbidity and mortality. Our objective was to determine if wound size during open cholecystectomy is associated with more complex biliary tract injuries.

Methods: Prospective cohort study performed between March 2006 and February 2007.

[Comparative study of soft diet or clear liquids in the resumption of oral intake in the postoperative period].

Background: The reinstitution of oral intake in patients who have undergone intraabdominal surgery has traditionally progressed in a stepwise fashion beginning with clear liquids, liquid diet and after an adequate tolerance regular diet.

Objective: To determine if the reinstitution of oral intake after major abdominal surgery with regular diet offers benefits into which it's not harmful for patients and reduce the in-hospital stay.

Type Of Study: Prospective, randomized, open study conducted between October 1996 to May 1997.
