Two hundred eighty patients were admitted to an intensive care stroke unit over a one-year period. Subsequent investigation indicated that only 199 of these patients actually had cerebral ischemic or hemorrhagic lesions, 10 had other cerebrovascular lesions, and the remaining 71 patients had unrelated diseases, predominantly seizures. Detailed analysis of 103 stroke patients revealed an overall incidence of 59% hypertension, and 72% had hypertensive, ischemic or valvular heart disease. Fifty percent of the patients had various cardiac arrhythmias, some of which were responsible for the acute cerebrovascular lesion. Fourteen patients died during the acute phase, 11 from apparently irreversible cerebral selling, mainly due to cerebral hemorrhage. Secondary complications such as pneumonia, pulmonary embolism, pressure sores and urinary infection were almost nonexistent, but beneficial effects on the primary cerebral lesions were more difficult to demonstrate.

1. Oral administration of DL-alpha-tocopheryl nicotinate (EN) (0-04 or 0-2 mmol day-1 kg-1) or DL-alpha-tocopharyl acetate (EA) (0-2 mmol day-1 kh-1) delayed the progress of hypertension in unilaterally nephrectomized rats, which were treated with deoxycorticosterone and salt, and in genetically hypertensive rats (SHR) which were given sodium chloride solution. Suppression of body weight gain, incidence of pneumonia and mortality were reduced by treatment with EN or EA. 2. Severe hypertension in old SHR (9 months) further progressed, when drinking water was replaced by sodium chloride solution, and four out of ten of these animals died of cerebral haemorrhage during 4 weeks. The administration of EN or EA prevented the increase in blood pressure and incidence of stroke.

Two months after renal transplantation, a 26-year-old man developed pneumonia that was recalcitrant to antibiotic therapy and proved by biopsy to be due to cytomegalovirus and Aspergillus fumigatus. Ten days later while on amphotericin B therapy, he developed an endophthalmitis proved by smear and culture of a vitreous aspiration to be caused by A. fumigatus. Despite intravitreous and systemic amphotericin B the vision deteriorated and the eye was enucleated. Microscopic examination disclosed an intense endophthalmitis with vitreous and retinal abscesses. The second patient was a 29-year-old woman who developed severe hypertension and graft rejection one month after renal transplant, despite massive immunosuppressive therapy with prednisone, azathioprine, and cobalt 60 irradiation. She developed pneumonia, meningitis, and died. A postmortem examination revealed disseminated aspergillosis. A single choroidal abscess due to Aspergillus with an associated retinal hemorrhage was observed in the left eye.

This study was based on a survey of the death certificates of Pu-Li Town in Taiwan, issued over the past 20 years from 1966 to 1985. Age-adjusted mortality trends as well as cause-specific mortality trends were analyzed and compared with nationwide Taiwan data. As a whole, Pu-Li had a higher age-adjusted mortality than that of the overall Taiwan area. This finding may result from a higher mortality from tuberculosis in Pu-Li. Based on these data, the five leading causes of death in Pu-Li were cerebro-vascular disease, accident, heart disease, cancer and tuberculosis. Hypertension and diabetes were the 5th and 6th leading causes of death in 1985 and ranked 12th and 13th, respectively, in 1966. This data point out the increasing importance of hypertension and diabetes rates in Pu-Li. Tuberculosis and pneumonia had been controlled, ranking from the 1st and 3rd in 1966 to the 10th and 12th, respectively, in 1985. Suicide, cancer, and accident were usually coded as the single cause of death without other co-existent causes of death noted, so that there was in most instances not much difference between analyses based on the underlying cause of death and multiple causes of death. However, this was not true for hypertension and diabetes. If multiple causes of death were analyzed, only 34.5% of hypertension and 66% of diabetes were coded as the underlying cause of death. 37.2% of cerebro-vascular diseases co-existed with hypertension, and 20.3% of diabetes co-existed with hypertension.

The neutropenia often seen in infants of hypertensive mothers (IHMs) at < 12 hours of age has been associated with nosocomial infection in the first 18 days of life. To assess maternal hypertension as an independent factor for nosocomial infection, we compared 101 low birth weight (< or = 2.00 kg) IHMs to a concurrent birth weight-matched group of infants of normotensive mothers (INMs). Infants without differential leukocyte counts at < 12 hours of age were excluded, leaving 93 IHMs and 98 INMs. The incidence of neutropenia at < 12 hours among IHMs was not significantly different from that among INMs (42/92 (45%) vs 37/98 (38%)). Nosocomial infection was more frequent in neutropenic IHMs than in neutropenic INMs (12/42 vs 2/37; p = 0.007). Infection in IHMs included omphalitis (2 infants), pneumonia (4), and sepsis with or without meningitis (6); INMs had cellulitis (1) and sepsis (1). The underlying mechanism(s) for this predisposition remains to be elucidated, although limited data suggest that neutropenia may be more severe and prolonged among IHMs.

Detailed invasive haemodynamic studies were performed in 27 of 32 patients with severe tetanus. Nineteen had severe uncomplicated tetanus and eight had associated major complications, chiefly infection and pulmonary complications. The results were compared with those obtained from 15 healthy male volunteers who served as controls. There were two deaths in 32 patients (mortality 6.25 per cent). Severe tetanus without major complications was characterized by a high output hyperkinetic circulatory state with tachycardia (heart rate 131 (19.2) beats/minute), increased stroke volume index (43.1 (10.7) ml/m2), increased cardiac index (5.48 (0.94) l/min/m2) and a normal left ventricular stroke work index (60.5 (15.9) g/m/m2). Volume loading demonstrated a significant haemodynamic response and increased vascular capacitance. Even so the maximum percent rise from baseline values of these indices after volume load was significantly higher in controls (p < 0.001). Autonomic cardiovascular disturbances affected both sympathetic and parasympathetic activity. Hypertension and tachycardia alternating with hypotension and bradycardia were related to sudden fluctuations in systemic vascular resistance. Our studies suggested some degree of myocardial dysfunction in patients with severe uncomplicated tetanus. The haemodynamics of severe tetanus were masked and altered by complicating infection, pneumonia, and atelectasis.

Polymyositis-dermatomyositis (PM-DM) is an inflammatory disease of muscle and skin mediated by autoimmune and cellular events. Most typically, muscle weakness is the usual presentation. This review emphasizes that often the systemic components of this disease may mask the usual presentation and actually may be the presenting and only manifestations; more often than not they are the causes of increased morbidity and mortality. In particular, the cardiopulmonary manifestations may dominate the disease course. Cardiac complications include congestive heart failure resulting from a primary cardiomyopathy, disrhythmias and atrioventricular conduction disturbances, sick sinus syndrome, and cor pulmonale either secondary to interstitial lung disease (ILD) or primary pulmonary artery hypertension. Recurrent aspiration pneumonia results from pharyngeal muscle involvement by the myositic process. Several histologic patterns of ILD can emerge with varying outcomes and responses to immunosuppresive therapy. Involvement of the muscles of respiration can lead to hypercapnic respiratory failure, diaphragmatic dysfunction, hypostatic pneumonia, and restrictive lung disease.

To investigate mortality patterns for domestic workers, proportional mortality ratios (PMRs) were calculated for the 1,382 female domestic workers who died in British Columbia at age 20 years or over between 1950 and 1984. This group experienced fewer deaths than expected from cerebrovascular accidents (PMR = 84) and hypertension (PMR = 39). The proportion of deaths from cirrhosis was higher than expected (PMR = 152). An excess of observed deaths was also noted for all accidents (PMR = 126), accidents due to environmental factors (PMR = 439), and homicide (PMR = 235). Mortality from pneumonia was elevated for domestic workers aged 20 to 65 (PMR = 180). Further studies using more sophisticated epidemiologic methods are necessary to evaluate whether these deaths are a result of occupational exposures or of poor socioeconomic conditions.

As part of a survey of the causes of perinatal mortality at Mpilo Maternity Hospital, 220 neonatal deaths and the mothers of 221 stillbirths were tested for HIV-1 antibodies. The HIV positive rate in neonatal deaths was 23.6% (95% confidence interval (CI) 18.0 to 29.2%), significantly higher than 15.4% (95% CI 10.6 to 20.1%) in stillbirths. Perinatal deaths from congenital malformations, birth asphyxia, pregnancy induced hypertension, placental abruption, and oFther non-infectious causes had similar low HIV positive rates averaging 8.1% (95% CI 3.9 to 12.3%). Deaths from septicaemia had a significantly greater rate of 39.3% (95% CI 27.0 to 51.6%) and the highest rate of 72.2% (95% CI 51.5 to 92.9%) was found in deaths from congenital infection other than syphilis, indicating that maternal HIV infection predisposes to neonatal septicaemia and congenital infection. Unexplained stillbirths also had a significantly greater rate of 22.4% (95% CI 10.7 to 34.1%), presumably because some died from unrecognised infection. The rate in deaths from congenital syphilis was 17.4% (95% CI 9.6 to 25.2%), indicating a significant but weak association between these two sexually transmitted diseases in Bulawayo. The rate in deaths from hyaline membrane disease was not significantly greater at 15.0% (95% CI 6.0 to 24.0%). By predisposing to infection, maternal HIV infection was estimated to increase the stillbirth rate by 1.6 times and the neonatal mortality rate by 2.7 times. It predisposed equally to early and late onset neonatal septicaemia, but more to infection from streptococci and staphylococci than from Gram negative enterobacteria. HIV positive deaths from congenital infection had respiratory distress and usually intrauterine growth retardation, hepatosplenomegaly, and congenital pneumonia on lung histology.

A 1987 questionnaire sponsored by the Health and Welfare Ministry concerning the clinical subsets and severity of systemic lupus erythematosus (SLE) was distributed to 93 medial facilities. A clinical analysis of the outcome and treatments was accomplished on one thousand six hundred and fourteen SLE patients fulfilling ARA criteria. The outcome was evaluated into 6 categories, namely; complete remission, incomplete remission, no change, gradual worsening, rapid worsening and unknown. Treatments included (1) anti-inflammatory drugs, (2) initial dose of prednisolone (PSL) below 29 mg/day, (3) initial dose of PSL from 30 to 59 mg/day, (4) initial dose of PSL above 60 mg/day, (5) pulse therapy, (6) immunosuppressants, (7) plasmapheresis, and (8) hemodialysis. Statistical significances were determined with ridit analysis. The severity of the disease for 1,614 SLE patients was evaluated by the judgement of each medical facility independently, separating it into 3 grades. As a result, 16.8% was evaluated as severe, 54.6% was evaluated as moderate, and 28.6% was evaluated as mild. Clinical subsets were divided into 3 categories according to the outcome; (1) those with high complete remission rates (serositis, convulsion, oral ulcers, unconsciousness, hemolytic anemia and so on), (2) those with high incomplete remission rates (lupus nephritis, digital gangrene, hypertension, peripheral neuropathy, erythema, Raynaud's phenomenon and so on), and (3) those with high rates of no change or worsening (aseptic bone necrosis, pulmonary hypertension, pneumonitis, chronic renal failure and so on). SLE patients with persistent proteinuria below 3.4 g/day, pulmonary hypertension, or pneumonitis treated with large doses of PSL such as an initial dose of PSL above 60 mg/day and/or pulse therapy had a significantly higher remission rate than those treated with small dosages of PSL. Hereafter, the establishment of modes of treatments for increasing the remission rates of intractable clinical subsets in highly desired.
