A 65-year-old black female with Sezary syndrome had generalized intractable pruritus, erythroderma, alopecia, onychogryphosis, lumphadenopathy and hepatomegaly. Abnormal lymphocytes with large, convoluted and grooved nuclei (Sezary cells) were identified in the skin and peripheral blood. A striking feature of her disease was severe, deforming arthropathy of the hands and knees, a clinical finding which has been described previously in only one patient with Sezary syndrome. At necropsy no associated lymphoma was found.

1. Aspiration of intrahepatic stones. This uses a catheter designed for selective aortography with a special probe, short and provided with a soft cap. The instrument is inserted in the hepatic canal to the contact of the stone, under TV guidance. Strong suction allows extraction. 2. Hepato-gastric prosthesis as palliative. Treatment for cancer of the biliary tract. A. Pezzer sound is placed in a dilated hepatic canal at one end, the other being fixed in the stomach. This is an ultimate solution for far advanced cases, that can only suppress the itching.

Clinical reports on 430 children with acute codeine intoxication are evaluated. Of 234 children who had taken more than 5 mg/kg body-weight, 8 had respiratroy arrest necessitating intubation and artificial ventilation; 2 of them died. In all other cases the intoxication produced one or more of the following symptoms: somnolence, ataxia, miosis, vomiting, rash, swelling, and itching of the skin, but no life-threatening side-effects. Close supervision of respiration is the main principle of management when more than 2 mg codeine/kg body-weight has been taken. Gastric voiding may be useful if done soon after ingestion. Charcoal and purgatives should be given in all cases.

The root and stem decoctions of Sinomenium acutum Rehd. et Wils. (formerly Sinomenium diversifolius Diels, one type of Fang-chi (Chinese)) have been used as a folk remedy for neuralgia and rheumatoid arthritis in many areas of the Far East. In Japan and China various viny plants have been identified as Fang-chi (Boi in Japanese) since antiquity. This uncertain nomenclature has made it difficult to evaluate the efficacy of the Fang-chi described in the classic literature. Among traditional Fang-chi plants only Sinomeniumacutum has been demonstrated to contain the alkaloid sinomenine, which is now known to be effective in neuralgia and rheumatic diseases. Sinomenine is a unique plant alkaloid, as it potently releases histamine in association with degranulation of tissue mast cells in mammalian tissues. This action occurs preferentially in the skin and joint capsules. The released histamine is responsible for the dominant pharmacological actions of sinomenine, such as vasodilatation, increased vascular permeability, acceleration of the thoracic and peripheral lymph flow, contraction of plain muscles, increased peristalsis of the intestines, and stimulation of gastric acid secretion. At toxic doses of sinomenine, convulsive central excitation was observed in most laboratory animals. Clinical side effects encountered with high doses of injected sinomenine or of decocted Sinomenium acutum were: injection site flare, pruritus in the head and upper part of the body, edema around the lips and eyelids, and temporary cephalalgia. Most of these side effects were reduced by classical antihistamines (H1-receptor antagonists). Daily subcutaneous injections of sinomenine for more than one week produced an analgesic effect in mice. Granulation tissue growth and adjuvant arthritis induced in rats were both inhibited by daily injections of a small dose of sinomenine hydrochloride or histamine dihydrochloride. These inhibitory effects were mediated through histamine H2-receptors probably on fibroblasts (for granulation tissue growth) and on T-cells (for adjuvant arthritis), since these effects were clearly inhibited by the H2-antagonist burimamide but not by the H1-antagonist mepyramine. The anti-rheumatic effect on Sinomenium acutum are probably genuine and can probably be attributed to the histamine-releasing properties of sinomenine.

A double-blind trial of (+)-cyanidanol-3 (2 g/day) versus placebo tablets was carried out in 100 patients with acute viral hepatitis. 51 received the drug and 49 placebo. (+)-Cyanidanol-3 accelerated the disappearance of HBsAg from the blood, lowered serum-bilirubin, and relieved symptoms such as anorexia, nausea, and pruritus. The drug was well tolerated. None of the patients had a relapse of acute hepatitis. Chronic active hepatitis developed in 1 of the placebo-treated patients. Thus, (+)-cyanidanol-3 seems to be of benefit in acute viral hepatitis.

The itch and erythematous responses induced by intradermal injection of histamine and PGE2 were studied in human skin. Both compounds produced a sensation of itch. The histamine-elicited flare reached a maximum in 3 min and had disappeared after 1 hours. PGE2 induced a similar flare reaction initially, but it was gradually replaced by a smaller, dusky and well delimited erythema. The itch and the flare-like erythema induced by either histamine or PGE2 were alleviated when the subjects were pretreated with the antihistaminic drug chlorcyclizine, thus indicating that at least part of the PGE2 response may be mediated via histamine release. However, when given combined in a mixture, histamine and PGE2 elicited itch of longer duration and flare of larger area than could be accounted for by simple additive histamine effects. Thus, PGE2 seems to potentiate the itch and flare responses induced by histamine in human skin.

63 patients of both sexes with pityriasis sicca or steatoides were examined for presence of Pityrosporum ovale on the scalp. Only those cases in which very numerous yeasts were seen in all squamae present in the preparation were considered positive. According to the severity or duration of pityriasis, 60% of the patients in this population represented severe cases and 38% refractory cases. A solution of econazole nitrate was applied as a spray, morning and evening, for a period of 10 to 20 days (mean). The overall assessment of the clinical effects of econazole nitrate indicated 56 favourable results, with complete disappearance of objective clinical signs in 47 cases; the course of pruritus proceeded roughly parallel with that of the objective signs. The mycological checking of the clinical results, performed at least 7 days after the conclusion of therapy, disclosed 6 failures and 57 successes. In 17 patients, the microscopic examination of squamae was complemented by culture before and after treatment: in all cases, the culture, positive before econazole nitrate therapy, became negative after treatment, thus confirming the results of direct examination. These data suggest that Pityrosporum ovale plays a pathogenetic part in pityriasis simplex capitis.

The association of primary biliary cirrhosis and coeliac disease, not previously reported, was observed in 4 patients. In each case, the two conditions were diagnosed simultaneously, and although symptoms were due to coeliac disease, initial investigation drew attention to the liver condition. All the patients responded to a gluten-free diet and remain well 2 years later. Primary biliary cirrhosis remains asymptomatic in 3 patients, but pruritus has developed in the 4th. The significance of this association is unclear and may merit formal study. Coeliac disease should be considered as a possible cause of unexplained weight loss in primary biliary cirrhosis.

20 out of 36 children (aged two to eight years) with atopic eczema completed a twelve-week, double-blind, controlled, crossover trial of an egg and cows' milk exclusion diet. During the first and third four-week periods, patients on an egg and cows' milk exclusion diet received a soya-based milk substitute (trial period) or an egg and cows' milk preparation (control period). Response was assessed in terms of eczema activity, number of areas affected, pruritus, sleeplessness, and antihistamine usage while on the two diets. During the middle period patients resumed their normal diet to minimise any carry-over effect. 14 patients responded more favourably to the antigen-avoidance diet than to the control diet, whereas only 1 responded more favourably to the control diet than the trial diet. Patients experienced more benefit during the first diet period than the second, whatever the nature of the diet. There was no correlation between a positive prick test to egg and cows' milk antigen and response to the trial diet.

The response to transcutaneous nerve stimulation (TNS)--a method used for treatment of chronic pain--was studied in 41 patients with itching of diverse etiology. At a first trial, 63% of the patients found that TNS ameliorated their itching, 20% reported complete relief. As a rule the effect lasted for many hours, although TNS was given only for 5-30 min. In 15 of the patients, having suffered from extensive pruritus for more than one year, TNS was given several times a day for 5-47 days. During this time the effect declined. Twelve patients were relieved initially, either partially or completely, but ultimately only 6 had a partial relief and in none had the itching disappeared completely. Only one patient wanted to continue the TNS therapy. The decreasing efficacy is discussed; probably there was an initial placebo effect which declined during the course of treatment. The results indicate that TNS is of limited value for treating chronic itching.
