A Case of Therapy-Resistant Folliculitis due to Adrenal Insufficiency?

A report on a 40-year-old patient with recalcitrant, suppurative folliculitis is presented. After years of unsuccessful treatment with conventional therapies, the patient was diagnosed with adrenal insufficiency with a low level of circulating cortisol. A few weeks after the patient was subjected to substitution therapy with hydrocortisone, his folliculitis resolved.

Body position and late postoperative nocturnal hypoxaemia.

Thirteen patients were monitored for nocturnal body position (supine vs. side) and arterial oxygen saturation pre-operatively and on the second postoperative night after major abdominal surgery. The number of positional changes were significantly decreased after operation (p < 0.

Validation of pulse oximetry for monitoring of hypoxaemic episodes in the late postoperative period.

We monitored 12 patients undergoing major abdominal surgery using a pulse oximeter (Nellcor N-200) and a transcutaneous oxygen tension monitor (TINA, Radiometer A/S) on the second or third night after operation. Of the shortest hypoxaemic episodes measured with the pulse oximeter (< or = 30 s duration), 78% also occurred in the transcutaneous oxygen tension measurement. Episodes of longer duration (> or = 1 min duration on the pulse oximeter) were, in 95% of cases, reflected in the transcutaneous oxygen tension measurement also.

No effect of oxygen therapy on myocardial ischaemia during gastroscopy.

Background: Myocardial ischaemia (defined as an ST-segment depression on ECG) may occur during upper gastrointestinal endoscopy, but the mechanism is still unknown. The aim of our study was to evaluate the effect of oxygen therapy and tachycardia on the occurrence of ST-segment depression during routine diagnostic esophagogastroduodenoscopy.

Methods: Eighty-nine consecutive patients were randomized to receive either oxygen (21/min by nasal prongs) or nothing during endoscopy, in which arterial oxygen saturation was measured by continuous pulse oximetry, and ECG was measured continuously with a Holter tape recorder.

Oxygen therapy reduces postoperative tachycardia.

Concomitant hypoxaemia and tachycardia in the postoperative period is unfavourable for the myocardium. Since hypoxaemia per se may be involved in the pathogenesis of postoperative tachycardia, we have studied the effect of oxygen therapy on tachycardia in 12 patients randomly allocated to blinded air or oxygen by facemask on the second or third day after major surgery. Inclusion criteria were arterial hypoxaemia (oxygen saturation < or = 92%) and increased heart rate (> 90 beat.
