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.

Wandering spleen syndrome is a rare condition in which absence or laxity of splenic fixing elements predisposes to an unusual location in the abdomen and an increasing risk of twisting and infarction. Its etiology may be congenital or acquired and clinical presentation is variable. Diagnosis is based on clinical suspicion, laboratory and imaging. ⋯ Laparoscopic splenectomy was completed. The pathology report showed ischemic necrosis of the organ. The patient progressed favorably and was discharged on the third postoperative day.

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.

A surveillance study was conducted at a University Hospital in Buenos Aires City aimed to assess the rates of colonization with carbapenemase-producing strains of Klebsiella pneumoniae, which are bacteria of utmost epidemiological importance. To this end, rectal swabs collected from all inpatients were cultured for the presence of these bacteria. Two point prevalence surveys showed high prevalence rates (up to 25%). ⋯ As for the prior use of antibiotics, results were close to statistical significance but without reaching it. Measures were implemented in order to control the spread of the microorganism in the acute setting and beyond. Upon implementation of such measures, a third prevalence survey was performed that showed a decrease in the horizontal transmission of the microorganism.
