Mucosal architecture of the small bowel in cases of psoriasis.
Using a strictly defined grading system to eliminate subjective assessment of mucosal architecture, the jejunal mucosa from cases of extensive psoriasis has been shown to be significantly different from that of normal controls obtained both in life and at postmortem examination. The same changes, however, are shown to occur in patients who are ill and losing weight for reasons other than psoriasis. Diminshed lactose utilization, demonstrated in extensive psoriasis, supports the suggestion of a decreased mucosal surface area in this disease.

Clinical evaluation of fibreoptic sigmoidoscopy employing the Olympus CF-SB colonoscope.
Fifty-one patients with large bowel disease were examined with the Olympus CF-SB fibreoptic colonoscope. With adequate bowel preparation and employing inhalational analgesia administered by a self-demand valve the whole sigmoid colon could be examined in the majority of patients within 30 minutes. In 23% of cases (12/51) the diagnosis was either made or confirmed by this procedure alone. Fibreoptic sigmoidoscopy is especially helpful in patients with either equivocal or failed barium enemas and is indicated in patients with unexplained rectal bleeding, extending the search for polyps and cancer, and studying patients with inflammatory bowel disease.About one quarter of biopsies taken from a flat mucosal surface with the Olympus flexible biopsy forceps may be insufficient for detailed histology due to their small size. For this reason multiple biopsies may be taken. Adequate biopsies were always obtained from projecting lesions and could be very accurately sited. Colour photography employing automatic exposure control is used to supplement the information obtained. It is concluded that fibreoptic sigmoidoscopy is a valuable additional investigation in selected patients with suspected disease of the large bowel and to date has been without complications.

Fingerprint changes in coeliac disease.
Study of the fingerprints of 73 patients with coeliac disease, taken carefully, showed changes varying between moderate epidermal ridge atrophy and actual loss of fingerprint patterns. Of the patients 63 had these abnormalities, compared with 3 out of 485 controls. A high degree of correlation existed between ridge atrophy and changes in the clinical state of patients with coeliac disease.

Neurological disorders and adult coeliac disease.
An investigation into the incidence of neurological disorder in 30 patients with adult coeliac disease has shown that three patients had severe depression, two had epileptiform convulsions, and one patient only had signs of involvement of the peripheral nervous system. Motor nerve conduction velocity was low in only one patient. When the nerve conduction velocities of the group on a gluten-free diet were compared with the group who were not on a gluten-free diet, there was no statistically significant difference. Similarly, nerve conduction velocities in patients with a low serum pyridoxal level were not significantly different from those with normal serum pyridoxal levels. Measurements of the serum level of pyridoxal in 30 patients confirmed that pyridoxine deficiency occurs in adult coeliac disease and that the restriction of gluten from the diet appeared to affect pyridoxal levels favourably.
Epsilon-aminocaproic acid therapy in ulcerative colitis.
On the supposition that excessive fibrinolysis at the rectal mucosal level may contribute to the pathogenesis of ulcerative colitis, 11 patients with this condition, in whom rectal bleeding was the predominant feature, were given a course of epsilon-aminocaproic acid therapy. Six patients responded dramatically to this treatment, there was a partial response in two, no effect in two others, and one patient found it necessary to discontinue the treatment after 48 hours because of the severity of side effects.
