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 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.

Drug hypersensitivity reactions (RHD) are those that present clinically as allergic. They can or cannot involve an immunologic mechanism of lesion. They are frequent and, occasionally, life threatening. ⋯ Positive symptoms included generalized pruritus, rash, urticaria, angioedema, rhinitis, bronchospasm, nausea and anaphylaxis. All the patients with positive tests had a good response to treatment. It can therefore be concluded that drug tests undertaken on individuals with suspected drug allergy, performed by experienced personnel and in controlled settings, are useful and safe to confirm drug hypersensitivity.

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.
