Ancestry and somatic profile predict acral melanoma origin and prognosis.

Acral melanoma, which is not ultraviolet (UV)-associated, is the most common type of melanoma in several low- and middle-income countries including Mexico. Latin American samples are significantly underrepresented in global cancer genomics studies, which directly affects patients in these regions as it is known that cancer risk and incidence may be influenced by ancestry and environmental exposures. To address this, here we characterise the genome and transcriptome of 128 acral melanoma tumours from 96 Mexican patients, a population notable because of its genetic admixture.

Surgical site occurrence after prophylactic use of mesh for prevention of incisional hernia in midline laparotomy: systematic review and meta-analysis of randomized clinical trials.

Background: The use of mesh is the standard for the prevention of incisional hernia (IH). However, the effect of surgical site occurrence (SSO) has never been compared. The aim of this meta-analysis was to evaluate the prevalence of SSO and measure its negative effect through the calculation of the number needed to treat for net effect (NNT net).

Abdominal wound dehiscence and incisional hernia prevention in midline laparotomy: a systematic review and network meta-analysis.

Background: Incisional hernia (IH) is the main complication after laparotomy. In an attempt to reduce this complication, mesh techniques and studies in which the closure technique is modified have been proposed. Both types are characterized by comparison with the closure described as standard or conventional: 1 × 1, mass, and continuous closure.

Genomic Profile in a Non-Seminoma Testicular Germ-Cell Tumor Cohort Reveals a Potential Biomarker of Sensitivity to Platinum-Based Therapy.

Despite having a favorable response to platinum-based chemotherapies, ~15% of Testicular Germ-Cell Tumor (TGCT) patients are platinum-resistant. Mortality rates among Latin American countries have remained constant over time, which makes the study of this population of particular interest. To gain insight into this phenomenon, we conducted whole-exome sequencing, microarray-based comparative genomic hybridization, and copy number analysis of 32 tumors from a Mexican cohort, of which 18 were platinum-sensitive and 14 were platinum-resistant.

Giant Condyloma Acuminata (Buschke-Lowenstein Tumor): Review of an Unusual Disease and Difficult to Manage.

Giant condyloma acuminatum (GCA) or Buschke-Loewenstein tumor is a rare disease, with an estimated prevalence of 0.1%. It was initially described in 1896 by Buschke and later in 1925 by Buschke and Loewenstein.

Association Between the Placement of a Double-J Catheter and the Risk of Urinary Tract Infection in Renal Transplantation Recipients: A Retrospective Cohort Study of 1038 Patients.

Background: The incidence of urinary complications in transplantation is 2% to 20%, which can be decreased with the use of a double-J catheter. The objective of this study was to determine the association between the use of the catheter and the probability of urinary tract infection (UTI).

Methods: We studied a retrospective cohort of 1038 patients divided into 2 groups: those treated with vs without a double-J catheter.

Intestinal Chloroma.

Chloromas are an atypical cellular infiltrate of immature granulocytic cells that can occur specially in patients with acute myelogenous leukemia (AML), but can be present in nonleukemic patients. Its clinical course will be dependent on its size and location, from asymptomatic to simulating a malignant gastrointestinal neoplasia. Definitive diagnosis is made upon an immunoprofile that is similar to that present in the blasts and precursor cells of acute myeloid leukemia.
