A reconfigurable, wearable, wireless ECG system.

New emerging concepts as "wireless hospital", "mobile healthcare" or "wearable telemonitoring" require the development of bio-signal acquisition devices to be easily integrated into the clinical routine. In this work, we present a new system for Electrocardiogram (ECG) acquisition and its processing, with wireless transmission on demand (either the complete ECG or only one alarm message, just in case a pathological heart rate detected). Size and power consumption are optimized in order to provide mobility and comfort to the patient.

Postoperative changes in serum interleukin-2 concentrations.

Objective: To evaluate the postoperative changes in circulating interleukin-2 (IL-2) concentration according to the severity of the surgical injury and other postoperative variables that could influence IL-2 production.

Design: Prospective observational study.

Setting: University hospital, Italy.

[Cytomegalovirus colitis simulating neoplasm in a patient with HIV infection].

Aim: Cytomegalovirus colitis occurs in at least 5-10% of patients with AIDS. The most usual form of clinical presentation is that of a chronic picture of diarrhea, fever and abdominal pain in a patient with AIDS with a CD4 lymphocyte count lower than 100/mm3, although it can be the diagnostic index for AIDS up to in 25% of the cases.

Methods: Cytomegalovirus colitis in a patient with AIDS was diagnosed by endoscopy and colonic biopsy.

[Cryptococcal meningitis and AIDS. Clinical description of 10 patients].

We have studied 10 patients with cryptococcal meningitis and AIDS. Nine of them were intravenous drug users and four have been previously diagnosed of AIDS. In 60% of them cryptococcal meningitis was the first opportunistic infection, and as group represented only 6.

[Pyomyositis in AIDS].

We describe two cases of pyomyositis in two patients with acquired immunodeficiency syndrome. Neither of the two cases had previous history of predisposing factors and both patients began with fever and pain at the site of the lesions. Aspiration by punction was required in addition to the antimicrobial therapy.
