Objective. To investigate the relationship between esophageal function and the extent of disease in a nonselected group of scleroderma patients, and to study gastric and small bowel motility in a group of scleroderma patients with more severe clinical manifestations.Methods. Esophageal function in 125 scleroderma patients was investigated by radiologic, endoscopic, manometric, and pH-metric techniques. Ten patients also underwent gastrointestinal (GI) manometric recording, both during fasting and after a standard meal.Results. Radiologic abnormalities of the esophagus were found in 55 of 81 patients (68%) and esophagitis in 45 of 125 (36%). No significant relationship was disclosed between GI symptoms, radiologic abnormalities, esophagitis grade, and the various disease subsets. However, the overall incidence of endoscopic esophagitis (irrespective of the degree) was significantly (P < 0.05) correlated with the patient subgroups, with 100% incidence of esophagitis in those having the more severe cutaneous involvement (type 111). Manometric abnormalities were documented in 80% of patients, and pathologic reflux in 78%. The severity of esophageal abnormalities on manometry significantly correlated with the severity of the disease, whereas no correlations were found with pH-metric data. Ninety percent of the . ~~~~~

A case of multiple pyogenic granuloma aVecting the penis of a 28 year old man is reported. The lesions were arranged in a floret-like fashion around the inner aspect of the prepuce and developed after circumcision for congenital phimosis. Histopathological examination of sections from a biopsy specimen of the papillomatous growths revealed the findings of pyogenic granuloma. In this patient, the pathogenesis of the lesions is probably related to the failure in surgical wound repair that followed circumcision. Problems of clinical and histopathological diVerential diagnosis are discussed. (Sex Transm Inf 1998;74:221-222)

Patch tests were carried out to evaluate the presence of a sensitization to some components of dialytic circuits in 17 uremic patients complaining of pruritus of unknown origin. Fragments of different dialyzer membranes, of tubing sets, of dialyzer membranes recently resterilized with ethylene oxide and the International Contact Dermatitis Research Group standard series substances were tested. Neither patients nor healthy subjects reacted positively to patch tests, which leads us to question the role of contact allergy in the determination of uremic pruritus.
