Most chronic renal failure patients suffer from generalized pruritus. An involvement of cutaneous nerve terminals in the pathogenesis of uremic pruritus has been suggested. Skin specimens from 24 uremic patients and 10 healthy subjects were processed with an indirect immunofluorescence method to investigate the presence and distribution of a number of neuronal markers and neuropeptides. No difference was found between the two groups in the distribution pattern of the positive nerve fibres. However, a reduction in the total number of skin nerve terminals in the uremic patients was detected. No correlation could be found between the immunohistochemical findings and the clinical features. Our results suggest that the skin innervation is altered in most chronic renal failure patients, possibly as a consequence of neuropathy.

Three patients of a French family demonstrated an association of multiple endocrine neoplasia type 2A (MEN 2A) with a pruritic scapular skin lesion. The lesions are similar to those described as familial cutaneous lichen amyloidosis in unrelated MEN 2A and medullary thyroid carcinoma families, but histological, immunohistochemical, and ultrastructural analysis of skin biopsies from each patient in the French family did not show amyloid deposition. The topography of the lesion follows dermatomes C8-D3. The patients report not only pruritus but also paresthesia and hyperalgesia, and one showed touch hypoesthesia and pain hyperesthesia in the area of the lesion. Such an association of cutaneous and neurological features suggests notalgia paresthetica (NP), a neuropathy of the posterior dorsal rami nerves. We thus suggest that the cutaneous lesions associated with MEN 2A might be secondary to pathology in the neural crest-derived dorsal sensory nerves. The amyloid, when present, would be secondary to scratching. We propose that patients presenting with familial NP be suspect for MEN 2A.

The lateral femoral cutaneus nerve is vulnerable to entrapment neuropathy where the nerve passes through the lateral end of the inguinal ligament. At the end of last century the clinical manifestation of this condition has been termed Meralgia paresthetica. It is a syndrome of pain, numbness, itching or other dysesthesias in the anterolateral aspect of the thigh, where perception of pinprick and touch often is diminished or lost. 36 patients were operated upon over a period of 17 years. After a short historical review, pathogenesis, clinical aspects and therapy of the syndrome are discussed. The correct surgical therapy is not the resection of the nerve, but its decompression, similar to the therapy of the entrapment of the median nerve at the wrist.

Six patients were studied to evaluate the efficacy and safety of plasma exchange (PE) in the treatment of primary biliary cirrhosis (PBC). All patients were affected by PBC at stage III-IV and presented symptoms refractory to pharmacologic therapy. Patients underwent PE for a mean period of 40 weeks (range 10-88). A mean of 33 liters (range 17-64) of plasma per patients was removed. Patients reported less fatigue (4/6), pruritus (5/5), nausea (3/3), Sjogren's syndrome (2/6), and painful neuropathy (2/3). A reduction of xanthomata was noted in one of the three affected patients. Definitive improvement was seen in the patient with Raynaud's phenomenon. A significant reduction was noted for serum cholesterol and gammaglobulins. ALT, AST, gamma-GT, alkaline phosphatase, bilirubin, prothrombin activity, AMA titers were not affected by PE. All patients suffered some mild adverse effects during PE. Two patients (IV stage) developed late edema and ascites after 34 and 44 weeks of treatment. We conclude that PE can be considered effective chronic treatment for advanced symptomatic PBC refractory to pharmacological therapy.

A study was carried out on 36 geriatric diabetic females (above 60 years). Marked exhaustion and significant loss of weight were common presenting complaints (60%) besides usual symptomatology. Only 25% patients were asymptomatic for diabetes. Generalised itching (20%) and pruritus vulvae (33.3%) were other common presenting complaints. Neuropathy was found to be the commonest complication being present in 77.7% patients, followed by retinopathy (50%) and nephropathy (27.7%). Hypertension was found to be associated in 44% patients and evidence of ischaemic heart disease was found in 42%. Development of nephropathy, retinopathy, neuropathy, and hypertension showed direct correlation with duration of illness ie, longer the history of diabetes higher was the incidence of complications.

At our institution, proctocolectomy with rectal mucosectomy and ileoanal anastomosis with endorectal pull-through is now the procedure of choice for young patients with chronic ulcerative colitis and familial polyposis. We have followed up 66 patients (37 male and 29 female, with a median age of 16 years) for at least 6 months after closure of the temporary ileostomy. The patients were seen regularly in follow-up or were sent a comprehensive questionnaire to assess their condition. Twenty-two patients had the construction of a J-pouch, and 44 had a straight ileo-anal pull-through. Stool frequency, day (median 4 to 7 stools) and night (median 1 to 3 stools), was similar in the two groups. Voluntary continence was excellent in both groups during waking hours. Occasional night-time incontinence in small volumes, mild perianal itching, and minimal bleeding from irritation were similar in both groups. Most of the patients could distinguish gas from stool. When medication was used, bulk agents were usually chosen, with a nonspecific antidiarrheal agent taken occasionally. A few patients with the straight ileo-anal pull-through expressed some dissatisfaction early during the follow-up period; however, all but two patients expressed satisfaction later. Of the 66 patients, 41 had at least one complication during the postoperative period; however, in 26 the complications were minor. The more severe complications included small bowel obstruction (11 patients requiring surgical decompression), infection (one patient requiring surgery), and transient neuropathy (three patients).

Five adult patients (four of them men) had episodic brachioradial pruritus associated with forearm paresthesia and hypalgesia. No cervical, shoulder, or forearm trauma was known. Onset was variable, but two had had the condition for more than ten years. In each, sensory alteration was detectable by pinprick and temperature in the distribution of the posterior cutaneous nerve of the forearm supplying the skin over the proximal portion of the brachioradial muscle. This seems to be a benign neuropathy.

Five patients with primary biliary cirrhosis and prolonged cholestasis underwent intensive plasmapheresis. The indications for plasmapheresis included intractable pruritus or hypercholesterolemia and xanthomatous neuropathy. Patients noted a rapid improvement of pruritus and fatigue which was sustained as long as plasmapheresis was continued. Cholesterol levels were lowered an average of 10.3 mmol/l and xanthomata were reduced in three of four patients. Two patients with painful neuropathy caused by xanthomata experienced relief of this symptom. The liver and spleen size were not affected by plasmapheresis, and activities of aminotransferases, alkaline phosphatase and titres of mitochondrial antibody remained unchanged. We conclude that plasmapheresis has a role in the therapeutic management of patients with advanced primary biliary cirrhosis who are disabled by the complications of pruritus, xanthomatous neuropathy, or hypercholesterolemia with xanthoma formation.

Two female patients with grade IV primary biliary cirrhosis, untractable pruritus, arthralgias and xanthomatous neuropathy in one case, underwent long term plasmapheresis for 30 months (on a continuous centrifugation cell separator) and 18 months (on capillary plasma filters). Plasma exchange were performed monthly and substitution achieved by diluted human serum albumin. No major side effect occurred. Pruritus, arthralgias and xanthomatous neuropathy greatly improved or even disappeared. The plasma levels of transaminases, albumin, globulin and clotting factors were stable, alkaline phosphatases slightly diminished. Bilirubin, after an initial fall at 6 months, increased again. Cholesterol stabilized at near normal values. Bile acids blood levels decreased in both cases.

After several years of occupational exposure to vibration, a man developed episodic vibratory hand swelling, erythema, and pruritus. He subsequently developed symptoms compatible with carpal tunnel syndrome, but his median nerve conduction velocity remained normal. After experimental vibration of the forearm, plasma histamine levels in the ipsilateral antecubital vein rose in association with localized angioedema and slowed median nerve conduction velocity. There was no evidence of other causes of angioedema. Occupational exposure to vibration may predispose to the development of vibratory angioedema, which may predispose to intermittent compression neuropathy.
