Crohn's disease is a chronic granulomatous disorder, which may involve any segment of the gastrointestinal tract from the mouth to the anus. Although extraintestinal manifestations are frequent, involvement of skin distant to the gastrointestinal tract is uncommon. We report a case of Crohn's disease affecting penile and scrotal skin.
Between July 1995 and July 1997 we diagnosed bronchiectasis confirmed by CT scan chest in 25 (18 men and 7 women) out of 295 hospitalised patients with HIV infection who suffered from lower respiratory infection. Median age at time of diagnosis of bronchiectasis was 32 years old. The patients were mostly intravenous drug addicts. In all cases a previous pulmonary infection was revealed (Pneumocystis carinii pneumonia, tuberculosis, recurrent pneumonia) with impairment of immune status (CD4 media = 64.8 mm3). Presence of persistent or intermittent cough with purulent sputum, repeated low respiratory infection and abnormal chest radiograph were correlated to bronchiectasis by chest CT scan. We conclude, that there is a significant occurrence of bronchiectasis in patients with HIV infections and pulmonary disease, thus increasing morbidity and mortality in these patients and being the cause of repeated hospitalisations due to bacterial respiratory infections.
UNLABELLED: The decision related to treatment initiation in smear-negative pulmonary TB is controversial. To determine differences between the characteristics of smear-negative, culture-positive pulmonary TB (Group D-) cases, we compared them with those patients who presented positive smear microscopy and cultures (Group D+). In addition, we compared the characteristics found in Group D- cases, in whom the treatment was started before confirmation by culture (sub-group D-TI) with those who were treated only after a positive culture was obtained (subgroup D-TD). We compared 270 patients of Group D+ with 48 of Group D-. The subgroups of Group D- (D-TI and D-TD) were compared with Group D+. Clinical symptoms, history, X-rays, other lung diseases and related extrapulmonary diseases were analysed Significant differences between groups D+ and D- related to age, history, X-rays and other lung diseases were found. There were no significant differences between Group D+ and subgroup D-TI, except for the age. The same and even more accentuated differences between Group D+ and D- were found between Group D+ and subgroup D-TD. CONCLUSIONS: Group D- was divided into to subgroups: D-TI, similar to D+, determined the decision to immediately start the treatment and D-TD, completely different; other possible diagnoses were considered and decision of treatment was delayed until a positive culture was obtained. This conduct proved to be the correct one in these cases where the diagnosis by culture was available.
Hidradenitis suppurativa or Verneuil's disease is usually a chronic, recurrent, suppurative and cicatricial disorder. It most often affects the skin of the axillae, groins and perineum, and less commonly the buttocks and upper thighs. A squamous cell carcinoma located in the hidradenitis-affected area is a rare complication. We present a review of the twenty-six published cases adding one of our own.
