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.

Nail Cancer: Review of the Two Main Types of an Underestimated Disease.

Neoplastic lesions (benign or malignant) in the nail region are rare when compared to lesions in the rest of the skin. Despite advances in diagnostic modalities, their diagnosis is frequently delayed or overlooked for days, months, or even years when they are misrecognized or when their approach is not appropriate. Undoubtedly, malignant tumors are the most important lesions since an inopportune diagnosis or treatment can drastically change the patient's prognosis.

Squamous Cell Carcinoma of the Nail, an Underdiagnosed and Underestimated Entity: A Series of Two Cases.

The nail apparatus is a complex area with great functional and cosmetic importance. The appearance of tumors is rare, frequently misdiagnosed with delaying the diagnosis. A series of cases is presented, where squamous cell carcinoma of nail apparatus underwent resection and reconstructive surgery in a relatively short time from their diagnosis, with a good oncological, functional, and cosmetic result.

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.

Superior Vena Cava Syndrome Due to Thymic Carcinoma.

The superior vena cava syndrome (SVCS) is caused by a mechanical obstruction; 90% are of neoplasic etiology (lung cancer (LC) and non-Hodgkin lymphoma (NHL) mostly), epithelial neoplasms of the thymus (NET) is a rare cause, thymic carcinoma (TC) causing less than 1% of cases. A 56-year-old male presented with a four-month history of dyspnea, dysphonia, facial and cervical edema and bilateral cervical lymphadenopathy. The tomography showed bilateral, mediastinal, retroperitoneal lymphadenopathies, and obstruction of the internal jugular vein, right apical pulmonary nodules.

[Hyperbilirrubinemia as a predictive factor of perforated appendicitis].

Background: Recent studies considered hyperbilirubinemia as a marker to identify the presence of perforated appendix. The aim of the study is to verify that the presence of hyperbilirubinemia is a useful marker to identify the presence of perforated appendix before surgery, and thereby, provide early treatment to avoid progression of the disease and its complications.

Methods: This is a retrospective study, which identified 225 patients, who met the inclusion and exclusion criteria, from January 2012 to October 2014 at the IMSS General Hospital 29, taking into account laboratory results and postoperative, performing a univariate, bivariate and multivariate analysis.
