Generalized pruritus appeared 2 years following resection of an adenocarcinoma of the stomach. The appearance of the pruritus was the presenting symptom of recurrence of the malignant process in the stomach as well as of its metastatic spread to the liver and to the lungs.

Pruritus is an important sign of localized or systemic disease and sometimes may be the only symptom of potentially fatal illness. Localized causes of pruritus include stasis dermatitis, atopic dermatitis, contact dermatitis, neurodermatitis and scabies. Generalized pruritus may be caused by environmental factors such as low humidity, skin diseases such as urticaria, or internal diseases such as biliary obstruction, renal failure, hematologic malignancy or acquired immunodeficiency syndrome. Therapy for pruritus depends on identification and treatment of the underlying cause. If no specific etiology is found, therapy is palliative. Avoidance of frequent bathing may be helpful, especially when xerosis plays a role. Topical emollients or short-term therapy with low-potency steroids may also be effective. Oral antihistamines provide nonspecific relief for many patients with intractable pruritus.

The analgesic and adverse effects of intrathecal methadone 5 mg, 10 mg and 20 mg were assessed and compared with intrathecal morphine 0.5 mg. The study was conducted on 38 patients who underwent total knee or hip replacement surgery. The intrathecal opioid was administered at the end of surgery and assessments began 1 h thereafter and continued for 24 h. Pain measurements, supplementary analgesia requirements, and adverse effects were recorded. Intrathecal morphine 0.5 mg provided effective and prolonged analgesia. Intrathecal methadone 5 mg, 10 mg, and 20 mg produced good analgesia of 4 h duration. Thereafter the median pain scores with intrathecal methadone were consistently higher (worse) than those with intrathecal morphine (P less than 0.05). The time to the onset of discomfort severe enough to require supplemental morphine was longer after intrathecal morphine than following methadone (15 h with morphine 0.5 mg; 6.25 h, 6.5 h and 6 h with methadone 5 mg, 10 mg, and 20 mg respectively: P less than 0.05). Central nervous system depression manifesting as respiratory depression, hypotension, and excessive drowsiness occurred in 3 of 8 patients injected with methadone 20 mg intrathecally. Generalized pruritus, nausea, vomiting, and urinary retention were common and equally distributed among the treatment groups. We conclude that both intrathecal morphine 0.5 mg and methadone 5, 10, and 20 mg provide excellent analgesia but that morphine has a more prolonged effect. Methadone 20 mg produced unacceptable side effects. Clinical evidence for rostral spread of methadone within the CSF, as indicated by facial itching and excessive drowsiness, was less apparent with 5 mg than with 10 and 20 mg. Various explanations for the observed differences between the drugs are discussed.

Generalized pruritus may be symptomatic of dermatologic disease or it can be a manifestation of a systemic disorder. When the cause of generalized pruritus is not immediately evident, careful clinical and laboratory evaluation and close follow-up are needed to ensure appropriate diagnosis and treatment.

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.

Three hundred diabetic and 100 nondiabetic hospital outpatients (both groups of comparable age and sex distribution) were assessed for the presence of generalized and localized pruritus. Pruritus vulvae was significantly more common in diabetic women (18.4%) than in controls (5.6%) and was significantly associated with poor diabetes control (mean glycosylated hemoglobin level less than 12%). Other forms of localized pruritus were equally common in diabetic and nondiabetic patients, regardless of glycosylated hemoglobin levels. Generalized pruritus was present in 14 diabetic patients, but in 5 cases the symptom was ascribed to intercurrent illness or drug administration. Thus, generalized pruritus without apparent cause was present in only 8 diabetic patients (2.7%) and was not significantly more common than in nondiabetic patients. It is doubtful if diabetes mellitus per se should be regarded as a cause of generalized or localized pruritus, other than pruritus vulvae.

Twenty-seven patients underwent percutaneous antegrade biliary drainage for obstructive jaundice. The serum bilirubin levels was elevated in all patients. Generalized pruritus was a major complaint. Twenty of the patients had had a laparotomy for malignant disease. Of the 24 patients in whom this method of drainage was successful, the obstructing lesion was found at the porta hepatis in 12 and in the extrahepatic bile ducts in 12. Metastatic disease was the commonest cause of obstruction. Following drainage the serum bilirubin level fell from a mean of 21.4 mg/dl (366 mumol/l) to a mean of 4.1 mg/dl (70.1 mumol/l) within a week. Pruritus was relieved. The major complications were transient cholangitis in five patients and inadvertent dislodgement of the catheter in four. In three of these patients another catheter was reinserted with ease. There was no peritonitis or uncontrolled bleeding. Twenty-one patients were able to leave hospital. Their mean survival time was 7.3 months. A multiperforated catheter manipulated through the obstruction has the advantage of permitting bile flow into the duodenum (antegrade) in contrast to external drainage (retrograde) by T- or U-tubes. Although the mean survival time with this method is similar to that with insertion of drainage tubes at the time of laparotomy, morbidity and mortality are reduced; this is important in view of the poor prognosis of bile duct obstruction due to malignant disease.

Generalized pruritus is a well-known, distressing symptom of various diseases, especially in hepatic cholestasis and chronic renal insufficiency. Its treatment is often unsatisfactory. In three patients with generalized pruritus, intravenous administration of the serotonin type 3 (5-HT3) receptor antagonist ondansetron induced a marked relief of itching. The effect was most pronounced in a patient with cholestasis-associated pruritus. It is suggested that serotonin, acting via 5-HT3 receptors, is involved in the generation and/or sensation of pruritus. Furthermore, 5-HT3 receptor antagonists may be a novel therapeutic principle for the treatment of pruritus.

Generalized pruritus is a notoriously troublesome condition for both patient and dermatologist. This paper describes the favourable therapeutic effect of transcutaneous electrical nerve stimulation (TENS) in two elderly patients with severe chronic generalized pruritus unresponsive to other treatment. The therapeutic application of TENS to the treatment of generalized pruritus has not previously been described.

Generalized itching, urticaria and anaphylactic shock developed in a 9-year-old girl on two separate occasions after she ingested acetaminophen. She was admitted to our hospital for observation during oral challenge. Total eosinophil counts, total serum IgE, IgA, IgG, IgM, C3, and C4, specific IgE antibodies to six common allergens, and skin prick tests to purified acetaminophen and acetylsalicylic acid (aspirin) were unremarkable. No reaction occurred on open challenge with acetylsalicylic acid and mefenamic acid. However, urticaria and itching sensation occurred 45 min after ingesting 50 mg of purified acetaminophen. Dizziness, shivering, tachycardia and fainting also developed later. These symptoms resolved after treatment with a diphenhydramine injection and intravenous infusion of normal saline. There was a marked increase in the blood histamine level after challenge. In vitro histamine release before oral challenge was also abnormally as high as 50%. In summary, she had an immediate allergic reaction to acetaminophen but was tolerant to acetylsalicylic acid.
