[Postoperative pyoderma gangrenosum. Apropos of 2 cases].

The typical lesion of pyoderma gangrenosum is a rapidly extending necrotic ulceration, often associated with a system affection, inflammatory colitis, hematologic affections, rheumatic disorders. In about 30% of cases it develops on the site of a sometimes minimal injury. In the two cases reported one developed in the region of a graft after excision of a basal cell epithelioma, the other in a peritoneal drainage scar after colon resection. In patients with pyoderma gangrenosum, initial discussion must involve possible causes of the cutaneous necrosis, but in the cases reported the clinical appearance and rapid progression of the lesion, and negative results of serial bacteriologic and mycologic examinations were in favor of this diagnosis. An accurate diagnosis is essential since general corticotherapy is usually necessary.

Menstrual cycle factors related to increased gastric contractile response to tube feeding.

Evidence exists that the ovarian hormones have a modulating effect on gastrointestinal (GI) motility, yet details are sketchy and little attention has been paid to the effect that fluctuating hormone levels might have on women who are receiving enteral feedings. This study compared gastric motility indices in response to tube feedings at two points in the menstrual cycle, concurrently measured ovarian hormone levels, and described three potentially related factors (ie, GI symptoms, uterine cramping pain, reports of daily stressors). Intragastric motility responses to enteral feedings were obtained on 28 women (aged 19-37) during menses and midfollicular phases of two menstrual cycles. Intragastric pressure changes were monitored by an open-tipped cannula method at rest, during and after tube feeding (Ensure, 240 ml at 8 ml/min). Serum estradiol and progesterone levels were measured by radioimmunoassay. Women completed a daily diary of symptoms and stressors throughout the two menstrual cycles. Results showed that intragastric pressure amplitudes and frequencies were higher at menses compared with midfollicular recordings. At menses, prefeeding and feeding gastric pressure amplitudes were positively correlated with uterine cramping pain and GI symptoms (ie, nausea). At menses, postfeeding contraction frequencies were also correlated with uterine cramping pain. At midfollicular phase, progesterone levels correlated with gastric motility indices; number of stressors indirectly correlated with gastric motility indices. These data suggest that gastric responses to enteral feeding are influenced by menstrual cycle phase.

Dietary fiber and distressing gastrointestinal symptoms in midlife women.

In this descriptive study, 20 midlife women experiencing chronic distressing gastrointestinal (GI) symptoms recorded GI symptom severity in a symptom diary for a 30-day period and dietary intake in a 9-day food record. A wide variability in GI symptom severity was noted. Significant negative relationships were present between dietary fiber intake and abdominal pain, awakening with abdominal pain, nausea, awakening with nausea, and awakening with rectal pain. No significant relationships were noted between amount of caffeine or alcohol intake and distressing GI symptoms.
