The Isoparaffins covered in this manuscript are branched aliphatic hydrocarbons with a carbon skeleton length ranging from approximately C10 to C15. They are used in the manufacture of liquid imaging toners, paint formulations, charcoal lighter fluid, furniture polishes and floor clearners. Potential exposure exists in the petroleum, printing and paint industries. Isoparaffins have a very low order of acute toxicity, being practically non-toxic by oral, dermal and inhalation routes. However, aspiration of liquid isoparaffins into the lungs during oral ingestion could result in severe pulmonary injury. Dermally, isoparaffins have produced slight to moderate irritation in animals and humans under occluded patch conditions where evaporation cannot freely occur. However, they are not irritating in non-occluded tests, which are a more realistic simulation of human exposure. They have not been found to be sensitizers in guinea pig or human patch testing. However, occasional rare idiosyncratic sensitization reactions in humans have been reported. Instillation of isoparaffins into rabbit eyes produces only slight irritation. Several studies have evaluated sensory irritation in laboratory animals or odor or sensory response in humans. When evaluated by a standard procedure to assess upper airway irritation, isoparaffins did not produce sensory irritation in mice exposed to up to 400 ppm isoparaffin in air. Human volunteers were exposed for six hours to 100 ppm isoparaffin. The subjects were given a self-administered questionnaire to evaluate symptoms, which included dryness of the mucous membranes, loss of appetite, nausea, vomiting, diarrhea, fatigue, headache, dizziness, feeling of inebriation, visual disturbances, tremor, muscular weakness, impairment of coordination or paresthesia. No symptoms associated with solvent exposure were observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Patients may be intolerant of zidovudine for several reasons, the most prominent being hematologic toxicity. In vitro studies demonstrate that zidovudine is toxic to the myeloid and erythroid precursors in the bone marrow; at concentrations of zidovudine near those associated with the optimal antiviral effect in vitro, the proliferative capability of these progenitor cells is reduced 50%-70%. The clinical manifestations of anemia and leukopenia generally are time- and dose-dependent. Strategies for alleviating the hematologic toxicity of zidovudine include the use of hematopoietic growth factors, such as erythropoietin, granulocyte colony-stimulating factor, or granulocyte-macrophage colony-stimulating factor. Myopathy, a recently recognized toxic effect of zidovudine, also appears to be time-dependent. Patients often complain of muscle weakness and discomfort and exhibit an associated elevation in creatine phosphokinase level; dose reduction or discontinuation of therapy generally is required. Some patients have experienced high fever, nausea, and vomiting; however, these effects are unusual and of unclear etiology. The substantial proportion of patients with AIDS or AIDS-related complex receiving zidovudine who experience hematologic or muscular toxicity may benefit from treatment with new antiviral agents, such as dideoxyinosine, with toxicity profiles different from that of zidovudine.

The diabetic hypersomolar state is defined by a serum glucose greater than 600 mg/dl and a serum osmolarity greater than 320 m Osm/L. Ketoacidosis or lactic acidosis may co-exist with DHS in the same patient. The incidence of this acute complication of diabetes is high enough (17.5 cases per 100,000 person-years) for primary care physicians to encounter a case every year or two. Predisposing factors include older age, female sex, nursing home residence, and infection. A substantial proportion of cases occur in patients with no prior history of diabetes. Common presenting signs include fatigue or weakness, polydipsia, polyuria, nausea, and alteration of consciousness. The mainstay of therapy is intravenous fluid replacement with close monitoring of glucose and electrolytes in a hospital setting. Current mortality figures are high, at 10% to 20%, and the chance of survival is adversely affected by older age, higher osmolarity, and the presence of an associated severe illness. Prevention includes screening for diabetes, educating diabetic patients and their care givers about the symptoms of hyperglycemia, prompt treatment of any infection in a diabetic person, avoidance of drugs that increase carbohydrate intolerance in diabetic people, and encouraging compliance with treatment of diabetes.

In the course of two and a half years we treated six diabetic women on account of lactate acidosis during concurrent biguanide administration. The patients were given an average dose of 290 mg Buformin/24 hours. Their mean age was 71 years. Three patients died, i.e. the mortality was 50%. All patients reported nausea, vomiting and abdominal pain. Two suffered from diarrhoea. Two patients suffered from renal failure and one from cardiac weakness. One patient was in coma. The mean lactate concentration was 14.7 mmol/l, pH on admission was 6.84. The patients were given on average 550 mmol bicarbonate. In two instances bicarbonate dialysis was used. The authors discuss the pathophysiology, clinical aspects and importance for treatment and prevention of lactate acidosis during biguanide treatment.

There has been increased recognition of adenosquamous lung carcinoma since the 1982 modification of World Health Organization (WHO) histologic criteria. However, data on clinical features of this histologic subtype were nonexistent. Medical records of 127 patients with adenosquamous lung carcinoma were reviewed to determine the clinical features, namely, age, race, sex, smoking history, asbestos exposure, symptoms present at the time of diagnosis, stage, treatments, and survival. The age distribution was: less than 40 yr, 3%; 40 to 49, 17%; 50 to 59, 28%; 60 to 69, 32%; 70 to 79, 18%; greater than or equal to 80, 2%. Men constituted 72%, and 90% were smokers. Four smokers had documented asbestos exposure. The symptoms in order of decreasing frequency were cough, weight loss, expectoration, anorexia, chest pain, dyspnea, weakness, hemoptysis, pneumonia, fever, nausea, vomiting, dizziness, and chills. Stage could be ascertained in 120 (95%) patients. Local stage constituted 10%, regional constituted 30%, and distant constituted 60%. Local stage had the best survival, with a projected 5-yr survival of 62%. Median survivals in regional and distant stages were 8 and 4 months, respectively. Symptoms of adenosquamous lung carcinoma were similar to other histologies. Most patients present in regional or distant stages. Local-stage patients had a good long-term survival after surgical excision of the tumor.

Two separate, but related, studies are described in which psychophysiological symptoms associated with chronic headache were examined. In the first study, the Psychosomatic Symptom Checklist (PSC) was administered to evaluate the presence of 15 different psychophysiological symptoms in 3 types of chronic headache patients (migraine, tension, and combined migraine and tension). Over 97% of these 438 patients reported at least one other symptom occurring at least monthly and 75% reported another intense symptom occurring at least once a week. The tension and combined headache groups reported significantly higher overall symptomatic distress than the migraine headache patients. The tension patients reported significantly higher scores on the backache and weakness items, while the migraine and combined headache patients reported significantly more nausea. The differences between the diagnostic groups is more a function of the intensity of the symptoms than the presence of the symptoms, since, for many individual symptoms, the percentage of patients reporting is nearly equal. In the second study, 150 patients from the original sample (50 from each diagnostic group) were reassessed using the PSC after psychological treatment of headache. There were significant decreases in total scores for all 3 groups with no significant differences between groups seen at post treatment. Different treatment effects were seen on the individual symptoms with 7 of the 15 showing significant reduction. Chronic headache does not occur in isolation and headache diagnostic groups do not differentiate well on other individual psychophysiological symptoms.

Prognostic factors for survival were analyzed retrospectively in 214 patients with brain metastases of the solid tumour type. The most frequent neurological signs and symptoms at diagnosis of cerebral involvement were headache-nausea-vomiting and focal weakness. Similar numbers of patients were found to have solitary metastasis and multiple lesions. Non-small cell lung cancer, small cell lung cancer, breast cancer, melanoma, and renal cell cancer comprised the majority of the primaries. Most patients received high-dose corticosteroids, while in a third, anticonvulsant agents were administered. Of 157 patients treated with radiation alone, or surgery with or without radiation, 110 experienced alleviation of symptoms or stabilisation of the disease. In 38 patients with a solitary lesion, craniotomy was carried out, either with or without postoperative radiation; the latter group showed the longest survival with a median of 37 wk. The remaining group of 73 patients with one brain metastasis had a median survival of only 15 wk. The 69 patients with multiple lesions who had been irradiated had a median survival of 15 wk, while that for 34 untreated patients was 7 wk. A short median survival of 11 and 13 wk, respectively, was observed in patients with concurrent progressive extracerebral disease and in those with progressive neurological symptoms regardless of treatment. It is concluded that in patients with a solitary brain metastasis without progressive extracerebral disease surgery should be considered the treatment of first choice aiming at a long-term survival with a good quality of life.

We experienced a case of hyperinfection with strongyloides stercoralis in a 64-year-old housewife who complained of severe epigastric pain associated with nausea, vomiting and general weakness for the period of one month. She received corticosteroid therapy for several months because of arthritis prior to admission. The diagnosis was confirmed by examination of gastroduodenal juice and gastrofiberoscopic biopsy. Stool examinations disclosed an abundance of the adult form of strongyloides stercoralis. Albendazole was given for treatment. The patient expired on the 79th hospital day.

Cabergoline (CAB) is a new oral dopaminergic compound showing a very long-lasting PRL-lowering activity and reported to be well tolerated. The efficacy and tolerability of chronic treatment with CAB in 30 female hyperprolactinemic patients, aged 18-52 yr (6 microadenomas, 3 macroadenomas, and 21 functional hyperprolactinemias), were studied. In a group of 10 patients who received CAB (0.8 mg once weekly or 0.4 mg twice weekly) for 8 weeks PRL levels normalized while on treatment and remained normal (8 patients) or greatly reduced (1 patient) for 1-2 months after discontinuation of the drug. Twenty-six patients underwent chronic treatment (6-12 months) with an initial dose of 0.5 mg once weekly, subsequently increased to 1-2 mg in 10 patients and decreased in the other 2. Due to severe side-effects CAB was discontinued in 3 patients, in 1, 8, and 12 weeks. A significant reduction of PRL levels was already observed after the first week of treatment (mean +/- SEM basal values, 90.1 +/- 13.3 vs. 29.5 +/- 6.3 micrograms/L; P less than 0.001). Twenty-two patients had normal PRL levels in 1-36 weeks (mean, 6 weeks) with 0.5-2 mg CAB. Twenty-two patients resumed regular menses; 2 patients became pregnant after 3-11 months of treatment. Thirteen patients complained of side-effects (nausea, hypotension, headache, gastric pain, dizziness, and weakness) that disappeared with time in 10 of them. The comparison with a previous bromocriptine treatment regimen in 20 patients had shown that the number of patients requiring discontinuation of the latter drug was significantly higher (7 vs. 3 patients; P less than 0.001). However, 2 patients who needed to discontinue CAB were able to tolerate bromocriptine therapy. A computed tomographic scan performed after 12 months of therapy in 7 patients showed a significant reduction (50%) of the adenoma in 5. In conclusion, our results show that CAB is a well tolerated new dopamine agonist with long-lasting activity that represents an advance in chronic medical treatment of hyperprolactinemic conditions.

We examined the impact of testis cancer and its curative therapies on the outlook of life, working activity, partner relationship and sexual function in 31 consecutive patients 18 to 51 years old (mean age 29.3 years, median 28 years) who already had undergone orchiectomy. Of the patients 13 subsequently were treated with chemotherapy alone, 6 with retroperitoneal lymph node dissection alone, and 7 with chemotherapy and an operation, while 5 seminoma patients were treated with radiotherapy. The patients were examined 3, 6 and 18 months after orchiectomy. Each patient was required to fill out a questionnaire to gather information relative to their work activities, emotional relationship with the partner and sexual life. The patients also completed an assessment form on the quality of life (Spitzer QL-Index) and a series of horizontal analogues to evaluate anxiety, mood, nausea, weakness and general health status. The statistical analysis of the linear and quadratic components for the variables under study was done with the general linear model for block design. Psychosocial adaptability of these patients, regardless of the treatment they underwent, in time became progressively less problematic and the development of psychosocial problems during the long-term adjustment was low. Only 2 patients reported worsening of the emotional relationship with the partner after treatment: 1 underwent chemotherapy and an operation, and 1 underwent radiotherapy. With regard to sexual life, no serious dysfunction was noted apart from the loss of ejaculation in 11 of 13 patients who underwent retroperitoneal lymph node dissection. Of our sample patients who had lost ejaculation only 2 suffered from a high state of anxiety. The anxiety scores on the last completed linear analogue were 2.6 and 4.1, whereas at the same time the mood scores were 1.9 and 4.4. Therefore, it is important for the clinician to assess the psychogenic aspect of this side effect when this type of operation is proposed.
