In a series of 84 various evaluable disseminated cancer patients treated with hydrazine sulfate as a result of a pharmaceutical-sponsored investigational new drug (IND) study, it was found that 59/84 or 70% of the cases improved subjectively and 14/84 or 17% improved objectively. Subjective responses included increased appetite with either weight gain or cessation of weight loss, increase in strength and improved performance status and decrease in pain. Objective responses included measurable tumor regression, disappearance of or decrease in neoplastic-associated disorders and long-term (over 1 year) 'stabilized condition'. Of the overall 59 subjective improvements 25 (42%) had no concurrent or prior (within 3 months) anticancer therapy of any type. Of the 14 objective improvements 7 (50%) had no concurrent or prior anticancer therapy. Of the remaining cases in which there was either concurrent or prior anticancer therapy, improvements occurred only after the addition of hydrazine sulfate to the treatment regimen. Duration of improvement was variable, from temporary to long-term and continuing. Side effects were mild, comprising for the most part low incidences of extremity paresthesias, nausea, pruritus and drowsiness; there was no indication of bone marrow depression.

A 27-year-old woman had a subacute onset of back pain, dysesthesia and weakness of both arms. Neurological examination revealed bilateral pyramidal signs, paresthesia of both hands and arms, and hypalgesia below T-4. CSF showed no abnormal findings. T2-weighted MR images revealed linear high signal within the cervical and upper thoracic cord, but no syrinx. The signs and symptoms resolved substantially within three months, with the exception of paroxysmal itching localized to the right forearm. At age 30, she experienced an acute onset of back pain, and dysesthesia of both feet. She developed weakness of both legs and urinary retention two days after the onset. Neurological examination showed bilateral pyramidal signs in the lower extremities, hypalgesia below T-4, hypopallesthesia on both legs, but no abnormalities in the upper extremities. CSF contained 8 white cells/mm3, protein 17 mg/dl and glucose 44 mg/dl. Oligoclonal bands were not detected. T1-weighted, proton density, and T2-weighted MR images revealed a syrinx formation within the spinal cord, extending from the level of T-2 to T-5. There was no evidence of spinal tumor. MRI of the brain revealed multiple areas of high signal intensity on T2-weighted image, consistent with multiple sclerosis. The signs and symptoms resolved substantially within two months. The syrinx within the thoracic cord reduced in size after two months and disappeared after three months. Two months after the second episode of myelopathy, she experienced right optic neuritis, resolving substantially within three weeks. This case was diagnosed as definite multiple sclerosis based on the clinical and radiological findings.(ABSTRACT TRUNCATED AT 250 WORDS)

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.

Treating keloids and hypertrophic scars is difficult. Here we report our method of treating recurrent keloid and hypertrophic scars. This involves surgical excision associated with intraoperative steroid injection, followed by routine weekly steroid injections for 2-5 weeks dependent on clinical signs and symptoms (pain, pruritus or paraesthesia), and monthly injections for another 3-6 months. The preliminary results thus far are promising.

Symptoms as an important sign of the effects of methyl bromide were studied in 56 male workers (37 currently exposed and 19 previously exposed) in a methyl bromide factory. The workers were 18 to 62 yr of age (mean age: 41) and were exposed from 1 to 25 yr (mean: 7 yr). They were compared to 56 age-matched referents with a standardized questionnaire. The results of pairwise comparison of the symptoms of the age-matched pairs of exposed and referent subjects showed that the occurrence of dizziness, numbness, paresthesia and weakness of extremities, nightmares, fatigue and dry and scaly skin was statistically significantly higher among the workers than among the referents. When the symptoms during the work shift (acute symptoms) were compared, irritation symptoms such as itching, bullae or reddish swollen hands and runny noses with nasal irritation were reported significantly more often in the exposed groups. The correlation of the symptoms among the exposed workers suggested that chronic symptoms are closely related to acute irritation symptoms and exposure duration. The results suggest that symptom inquiry is useful for detecting the possible effects of exposure to methyl bromide.

An association between the ingestion tryptophan and a syndrome characterized by scleroderma-like skin abnormalities, fasciitis, and eosinophilia has recently been recognized in the United States. We report the clinical and histopathological findings in nine patients and the results of biochemical analyses of tryptophan metabolism in seven patients with this syndrome. Edema of the extremities, frequently accompanied by pruritus, paresthesia, and myalgia, developed in the nine patients (six women and three men; age range, 30 to 66 years) 1 to 18 months after the start of therapy with tryptophan (1.5 to 3.0 g daily) for insomnia, depression, or obesity. Five patients were taking drugs (benzodiazepines) known to inhibit hypothalamic-pituitary-adrenal function, and one had adrenal insufficiency. All had blood eosinophilia in the acute phase of their illness (mean eosinophil count [+/- SD], 3.62 +/- 2.87 X 10(9) cells per liter). All had histopathological changes in the dermis and subcutaneous tissue typical of scleroderma, and seven patients had eosinophils. The fascia was inflamed and fibrotic, and adjacent skeletal muscle often showed perifascicular inflammation. Tryptophan was discontinued in all patients, and eight received prednisone. The cutaneous symptoms improved, but only two patients had complete resolution of their illness. The patients had plasma levels of tryptophan before and after an oral dose of tryptophan that were similar to those in normal subjects. Plasma levels of L-kynurenine and quinolinic acid, which are metabolites of tryptophan, were significantly higher in four patients with active disease than in three patients studied after eosinophilia had resolved or in five normal subjects (P less than 0.001)--findings consistent with the activation of the enzyme indoleamine-2,3-dioxygenase. This illness resembles eosinophilic fasciitis and probably represents one aspect of the recently reported eosinophilia-myalgia syndrome. The development of the syndrome may result from a confluence of several factors, including the ingestion of tryptophan, exposure to agents that activate indoleamine-2,3-dioxygenase, and possibly, impaired function of the hypothalamic-pituitary-adrenal axis.

The process of nociception, the anatomy of the epidural space, and the placement of the epidural catheter are reviewed, and the pharmacology and pharmacokinetics, analgesic efficacy, and potential adverse effects of epidurally administered narcotics and local anesthetics are discussed, as well as patient monitoring standards and solution preparation guidelines for these agents. The epidural space is located between the dura mater (the outer-most membrane surrounding the spinal cord) and the vertebral canal. The site of catheter placement is determined by the dermatomes corresponding to the site of desired analgesia. The primary factors that differentiate epidural narcotics are related to their pharmacokinetic profiles. Morphine, which is hydrophilic, has a slower onset of action and a longer duration of analgesia than lipophilic compounds such as fentanyl; morphine also results in less segmentalization (the degree to which analgesia is limited to discrete dermatomal segments corresponding to the level of the epidural narcotic injection) than is seen with lipophilic compounds. Studies have shown that epidural narcotics provide superior pain relief compared with systemic narcotics. Common adverse effects associated with therapeutic doses of intraspinal narcotics include itching, nausea and vomiting, urinary retention, and sedation; respiratory depression is uncommon after epidural administration of narcotics. The most bothersome adverse effect encountered with analgesic doses of local anesthetics is paresthesia. Solutions for epidural administration must be sterile and preservative free. Epidural administration of narcotics and local anesthetics seems to provide better pain relief than conventional methods but may be associated with more bothersome adverse effects.

Cases of ciguatera fish poisoning no longer are confined to endemic areas. This makes awareness of this entity important. The diagnosis usually is made by the presence of gastrointestinal symptoms, nausea, vomiting, and diarrhea, and of neurological symptoms such as paresthesias, paresis, and pruritus. The detection of ciguatoxin in the ingested fish by any of the available bioassays, will confirm the diagnosis. The treatment of this food poisoning is supportive, although intravenous mannitol is reported to be safe and effective. The prognosis is good and complete recovery is to be expected. However, relapses can occur, especially on re-exposure to the toxin.

A multi-institutional double blind study was performed in 66 patients in order to evaluate the action of human leukocyte interferon, type alpha (IFN) in lesions produced by herpes simplex virus. Lesions were localized in genital area in 34 cases and in facial area in 32 of them. From the total, 38 patients were treated with 7,000 Ul/gm. of interferon ointment and 28 with carbowax 4,000 as placebo. The symptoms pain, ardor, itching and paresthesia were evaluated asking to patients. Erythema, vesicles, crust, scale adenopathy were objectivated. Signs and symptoms were controlled on days 3 and 7 of treatment. In 42 patients, lesions specimens were taken for virus isolation. In 23 of them, cytopathic effect was detected (54.76%). Results showed a rapid relief from pain (p less than 0.05), ardor (p less than 0.01) and paresthesia (p less than 0.001) and also accelerated healing of vesicles in patients treated with interferon. Tendency to reduce the total time of the disease in those patients treated with IFN was observed.

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.
