Of 434 cases of epidural, subdural, and intracranial haematomas published in the last 2-3 decades, 61 had developed following spinal, epidural or caudal anaesthetic procedures; 29 haematomas were around the spinal cord and 32, within the cranium. The most frequent secondary cause of this complication was pre-, intra-, or postoperative administration of drugs influencing blood coagulation. Simultaneous traumatic and haemorrhagic punctures may favour the development of a haematoma. The most common primary symptom of lumbothoracic haematomas was back pain with and without radicular symptoms, while intracranial haematomas were predominantly accompanied by persistent headache. Continuous postoperative follow-up of such patients is essential. Postoperative results of laminectomies for lumbothoracic haematomas has been found to on the time interval between the first symptoms and the start of surgery. If surgery is performed within 8 h after the onset of paraplegia the prognosis is relatively good. Compared with the frequency of spinal, epidural, and caudal anaesthetic procedures throughout the world, haematomas of the lumbothoracic or cranial region are extremely rare complications.

The study aimed at evaluating tolerability and efficacy of the combination enalapril 20 mg with hydrochlorothiazide 12.5 mg (co-renitec) as first line therapy in black patients with mild to moderate primary hypertension. Fifty patients completed a twelve weeks of open clinical study preceded by two weeks of washout period. They were evaluated every four weeks and haematological, biochemical urine microscopy and electrocardiographic tests were undertaken before the start and after the completion of study. Pre-treatment values of mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 172.16 mm hg (+/- 20.41) and 104.38 mm hg (+/- 7.339) respectively. The usual daily dosage was one tablet which was increased to two after eight weeks in case the DBP was not normalized, i.e. less than or equal to 95 mm hg. In 44 (88%) patients, the DBP was normalised at the end of the study period; three patients (6%) were resistant to treatment and another three (6%) exhibited labile response to the treatment. Clinical tolerance was considered to be very good with only five episodes of headache, backache and anxiety, probably not related to the test drug. Biological tolerance was excellent: there was no change in the haematologic parameters; there was a decrease of 5% in mean blood urea, of 9% in the mean serum creatinine and of 4% in the mean serum uric acid and a 5% increase in plasma potassium from 3.99 to 4.28 mmol/l.(ABSTRACT TRUNCATED AT 250 WORDS)

To ascertain the range of neurological problems in patients with systemic cancer, we prospectively evaluated neurological symptoms, neurological diagnoses, and primary tumors in all patients with a history of systemic cancer examined by the Department of Neurology at the Memorial Sloan-Kettering Cancer Center, from Jul 1, 1990, to Dec 31, 1990. Of the 815 patients seen for neurological symptoms, less than half (45.2%) had metastatic involvement of the nervous system. The three most common symptoms were back pain (18.2%), altered mental status (17.1%), and headache (15.4%). The most common neurological diagnosis was brain metastasis (15.9%), followed by metabolic encephalopathy (10.2%), pain associated with bone metastases only (9.9%), and epidural extension or metastasis of tumor (8.4%). Of 133 patients with undiagnosed back or neck pain, 44 (33%) had epidural extension or metastases from tumor and 40 (30%) had pain associated with vertebral metastases only. In 15 (11%) the cause for the back pain was unrelated to metastatic disease. Of 132 patients seen on initial consultation for altered mental status, metabolic encephalopathy was the major neurological diagnosis (80; 61%); 20 (15%) had intracranial metastases. Of 97 patients with undiagnosed headache, 59 (61%) had a nonstructural cause. Fifty-three of these patients had either migraine, tension headache, or headache related to systemic illness (e.g., fever, sepsis). These results indicate that even in patients with systemic cancer, a group particularly prone to developing neurological disease that can be diagnosed radiologically, the role of clinicians remains important in helping distinguish noncancer-related and nonmetastatic neurological problems.

Three siblings with inhaled elemental mercury toxicity are described, and the signs and symptoms of mercury toxicity, interpretation of mercury concentrations, and management of elemental mercury exposure are reviewed. A 4-year-old girl was admitted to the hospital with a history of fever and increasing irritability, fatigue, malaise, insomnia, headache, anorexia, and ataxia. She was discharged two days later with a diagnosis of acute cerebellar ataxia. During the following 18 days, the child's condition worsened, and she was rehospitalized. Meanwhile her 11-year-old sister was hospitalized for evaluation of fatigue, weakness, lower back pain, and ataxia. The older girl's blood mercury concentration, at 5.5 micrograms/dL, was in the toxic range. Twenty-four-hour urine mercury screening confirmed mercury intoxication in both children. Questioning revealed that the girls' brother had recently spilled 0.5-1 oz of elemental mercury in the house. All family members underwent blood and urine mercury testing. The brother underwent a dimercaprol challenge to determine his tissue mercury burden, which was found to be greater than 2.4 micrograms/dL. The sisters underwent two courses of chelation therapy with dimercaprol. Symptoms persisted in all three children, and they underwent five 10-day cycles of N-acetyl-D,L-penicillamine (NAP) therapy; the youngest underwent a third dimercaprol regimen. All siblings continued NAP chelation therapy because of extensive tissue mercury burden until the results of repeated urine mercury concentration determinations were normal.(ABSTRACT TRUNCATED AT 250 WORDS)

Nephropathia epidemica (NE) in Scandinavia is a zoonosis caused by Puumala virus. The main animal reservoir is the bank vole. NE predominantly affects men. Its annual incidence varies in a cyclic fashion, with peaks occurring every third to fourth year. The clinical picture of NE in Scandinavia is similar to that of hemorrhagic fever with renal syndrome in other parts of the world, although NE generally has a milder course. The case-fatality rate is approximately 0.2%. The most common clinical findings in NE are an acute onset of symptoms, fever (greater than or equal to 38 degrees C), oliguria, headache, back pain, and polyuria. Hemorrhagic manifestations are seen in about one-third of cases, and up to 5% of patients have gastrointestinal bleeding or disseminated intravascular coagulation. Thrombocytopenia occurs in a majority of patients. In the acute phase, the glomerular filtration rate is markedly decreased and tubular dysfunction is evident. Most patients with NE recover within 6 months.

After at least 6 months on conventional hemodialysis (cellulosic dialyzers, acetate dialysate, and a 3- to 4-hour treatment time), 56 patients were changed to short-time hemodialysis (less than 180 minutes) using polysulfone dialyzers and bicarbonate-containing dialysate. Treatment time decreased (191 +/- 5 v 147 +/- 5 min; P = 0.001), while Kt/V (1.22 +/- 0.04 v 1.29 +/- 0.06; P = NS) and normalized protein catabolic rate (pcr) (1.10 +/- 0.05 v 1.10 +/- 0.07 g/kg/d; P = NS) remained constant. When compared with the conventional period, 30 months of short-time hemodialysis resulted in no changes in predialysis blood pressure (BP) (151 +/- 2/84 +/- 1 v 151 +/- 2/86 +/- 1 mm Hg), postdialysis BP (144 +/- 2/81 +/- 1 v 143 +/- 3/84 +/- 1 mm Hg), interdialytic weight gain (2.4 +/- 0.1 v 2.7 +/- 0.2 kg), or blood urea nitrogen (BUN) (26.1 +/- 0.71 v 25.3 +/- 1.07 mmol/L [73 +/- 2 v 71 +/- 3 mg/dL]). Shorter treatment times were not associated with an increase in intradialytic complications. Actually, the frequency (%) of dialysis treatments associated with nausea (5.94 +/- 1.33 v 2.21 +/- 0.52), vomiting (3.12 +/- 0.87 v 0.54 +/- 0.14; P less than 0.05), headaches (5.60 +/- 1.13 v 2.03 +/- 0.52; P less than 0.05), and back pain (0.91 +/- 0.25 v 0.05 +/- 0.05; P less than 0.05) was decreased.(ABSTRACT TRUNCATED AT 250 WORDS)

Medication usage by crewmembers in the preflight and inflight mission periods is common in the Shuttle Program. The most common medical reports for which medication is used are: space motion sickness (SMS), sleeplessness, headache, and backache. A number of medications are available in the Shuttle Medical Kit to treat these problems. Currently, astronauts test all frequently used medications before mission assignment to identify potential side-effects, problems related to performance, personal likes/dislikes, and individual therapeutic effect. However, microgravity-induced changes in drug pharmacokinetics, in combination with multiple operational factors, may significantly alter crew-member responses inflight. This article discusses those factors that may impact pharmacologic efficacy during Shuttle missions.

The authors report a case of spinal subdural hematoma in a 51-year-old man who experienced a sudden onset of back pain accompanied by vomiting and headache without paralysis or paraparesis. CT Scan, myelography and MRI revealed a subdural hematoma at the levels of 6th, 7th and 8th thoracic vertebrales. Laminectomy allowed the removal of an encapsulated cyst formation filled with xanthochromic fluid and some blood clots. The follow-up was uneventful.

Health workers took blood samples from 41 black women living in the greater Harare area of Zimbabwe before they began taking a combines oral contraceptive (OC) with 30 mcg ethinyl estradiol and 150 mg desogestrel (Marvelon formulation) and 3, 6, 9, and 12 months after taking it to conduct metabolic tests. They also recruited 190 other black women from Harare and rural Chiweshe, Mazowe, and Domboshawa populations taking the same new generation progestogen-containing OC to determine the efficacy, acceptability, and safety of the OC. Only high density lipid (HDL) cholesterol levels rose considerably between pretreatment and 12 months (0.94-1.3 mmol/ml; p.05). Low density lipid (LDL) cholesterol levels remained basically the same. This accounted for the significant rise of the HDL cholesterol/LDL cholesterol ratio over 12 months from 0.41 to 0.61. Triglyceride levels did not rise significantly and always stayed within the normal range. No woman became pregnant during the clinical trial. 2% experienced minor side effects including backache, spotting, headache, and nausea. Body weight and blood pressure did not change significantly. Sociodemographic reasons accounted for the high dropout rate (60%). The leading reason was change of address since many women were migrant farm workers. Since HDL levels rose and LDL levels were the same, this OC appears to have a reduced risk of atherosclerosis and cardiovascular disease. The findings indicated that the Marvelon formulation OC did not adversely affect lipid metabolism and therefore did not increase the risk of atherosclerosis or cardiovascular disease among these women. It also effectively protected them from pregnancy and induced minimal side effects.

The correlates of back pain were analyzed by logistic regression in 2 groups of middle-aged Dutch women, 236 with recurrent back pain at the beginning of the study and 241 without; and followed, in the same subjects 9 years later. Subjects were selected from a population survey of rheumatic and cardiovascular diseases in Zoetermeer, the Hague, Holland, in 1975-1978. Initially they took a questionnaire, and had their height, weight, blood pressure, spinal movement and body mass recorded. In the follow up in 1985-1986 a questionnaire, lumbar spine radiographs, height and weight were taken. Initially a higher proportion of women with back pain had taken oral contraceptives, smoked, had cystitis, had frequent headaches currently, and other joint pain. Those with back pain and more limited spinal movement, less ability to do household tasks, 5.5% had changed jobs as a result of back pain, 54% had pain 3 months, and 46% had resorted to bed rest. At the follow up, those with back pain were more likely to use estrogens. 72% of those who initially had back pain still had it, compared to 24% of the initially pain-free now having back pain(relative risk 2.99). Continuing back pain was correlated only with pain in hip or knee, on univariate analysis and stepwise logistic regression. This is the 1st report of an association between use of oral contraceptives and recurrent back pain.
