The pudendal nerve entrapment is an entity understudied by diagnosis imaging. Various causes are recognized in relation to difficult labors, rectal, perineal, urological and gynecological surgery, pelvic trauma fracture, bones tumors and compression by tumors or pelvic pseudotumors. ⋯ The radiologist should be acquainted with the complex anatomy of the pelvic floor, particularly on the path of pudendal nerve studied by magnetic resonance imaging. High resolution magnetic resonance neurography should be used as a complementary diagnostic study along with clinical and electrophysiological examinations in patients with suspected pudendal nerve neuralgia.

Anaphylaxis during anesthesia is an unpredictable, severe, and rare reaction. It has an incidence of 1/10 000 to 1/20 000 surgeries. In most series, the responsible drugs include neuromuscular blocking agents, latex, or antibiotics. ⋯ The responsible drugs during surgery anaphylaxis were neuromuscular blocking agents, latex, patent blue, and ranitidine. Ortho-phthalaldehyde (OPA) was identified during endoscopic studies; latex was responsible in transvaginal ultrasounds; and amoxicillin in the dental procedure. The aim of the present article is to review our experience studying allergic systemic reactions and anaphylaxis during general anesthesia and medical procedures, emphasizing the severity of these reactions and the need for causative drug identification.

Hypothyroidism is a frequently diagnosed and simply treated disease. If not recognised, however, in time it may develop into the most severe manifestation of hypothyroidism known as myxedema coma. ⋯ It mainly affects elderly women, often occurring in winter and is relatively rare. It can be considered a form of decompensated hypothyroidism often triggered by a variety of non-thyroid conditions or diseases provoking an extremely severe condition of multiple system failure with lethal consequences unless an early diagnosis is made and an aggressive treatment is administered.

The objective of this study was to evaluate the efficacy of age, creatinine and ejection fraction (ACEF) score and the modified ACEFCG model, incorporating creatinine clearance, to predict immediate operative mortality risk of patients undergoing elective cardiac surgery. A retrospective analysis was performed of prospectively collected data between 2012 and 2015, from a series of 1190 adult patients who underwent elective cardiac surgery. Operative risk mortality was assessed with ACEF, ACEFCG and EuroSCORE II. ⋯ For clinical use, the ACEF score seems to be adequate to predict mortality in low- and intermediate-risk patients. Though the ACEFCG score had a better discriminatory power and calibration, it tended to overestimate the expected risk. Since ideally, a simpler risk stratification score should be desirable for bedside clinical use, the ACEF model reasonably met the expected performance in our population.

Case Reports
Hantavirus pulmonary syndrome in Tucumán province associated to an unexpected viral genotype.
We describe the characterization of the viral genotype involved in the first case of hantavirus pulmonary syndrome reported in Tucumán, a Northwestern province of Argentina. A 23-year-old woman, with no record of travel history and previously diagnosed with an antiphospholipid syndrome, died after 11 days of severe cardiopulmonary insufficiency. Among the four endemic regions of hantavirus pulmonary syndrome in Argentina, the Northwest Region has the highest incidence, exceeding 50% of all reported cases in the country. ⋯ Remarkably, the viral genotype characterized in this case showed higher nucleotide identity with the Andes-BsAs genotype most prevalent in Buenos Aires province, located 1400 km apart from Tucumán, than with any of the commonly found genotypes in the Northwest Region. The Andes-BsAs genotype has been associated with 30% lethality and interhuman transmission in Buenos Aires province. Interhuman transmission cannot be ruled out in the present case.
