The authors studied 43 cases of arterial hypertension in pregnancy in an attempt to determine the efficiency and safety of different anti-hypertensive drugs. The patients were divided into two major groups: arterial hypertension which revealed itself during pregnancy (true toxaemias of pregnancy and relapsing toxaemias), and arterial hypertensions which were added on to a pre-existing pathology (arterial hypertension, diabetes, chronic nephritis). The cases in these different classes were then divided into two definite groups according to the need for therapy: the first group was treated by rest and hydrallazine as a single therapeutic agent. In the second group multiple agents were needed because of the arterial hypertension, and one was a beta-blocker. Complications were found particularly in the second group of true toxaemias of pregnancy where unfortunately 5 fetal deaths occurred that were attributable to the severity of the hypertension more than to the beta-blockers, which were administered for longer and in higher doses without major complications in recurrent toxaemias and pre-existing arterial hypertension cases.

One hundred five patients were treated effectively with topically applied tetracycline in an ethanol-water solution with n-decyl methyl sulfoxide, and observed for a year. Comedones and cystic lesions were least responsive to topical tetracycline. Side effects, which were minor, included yellow staining of facial skin and stinging after application. Two patients, one with juvenile diabetes and one with congenital nephritis, successfully used the preparation without adverse effects.

The role of enteroviruses in certain specific disease--cardiac disease, nephritis, diabetes, and hemorrhagic conjunctivitis--is examined. It has now been well documented that Coxsackievirus B (types CB1 through CB5 but not CB6) is the main pathogen involved in various clinical forms of viral heart disease. Coxsackievirus A (CA4 and CA16) and echovirus (types 9 and 22) may also be associated with viral heart disease. In regard to the etiologic role of enteroviruses in nephritis, pancreatitis, and diabetes, again CBV, especially CB3 and CB4, has been suspected, but the data are controversial and further studies are needed. Hemorrhagic conjunctivitis, a newly observed clinical entity, is caused by enterovirus 70. It has spread to four continents (not including the Americas) in a pandemic fashion since 1969 and is now one of the common eye infections in these areas. The virus has some neurovirulence, and motor paralysis is known to occur as a complication; hence it should be carefully watched in the future.

Long-acting oral contraceptives (OCs) for women were available for clinical experimentation in 1969. Through the country, 29 provinces, cities, and autonomous regions participated in this expirement. Based upon the cases between 1969 and 1976 findings from this expirement can be summarized as follows: 1) the 3 types of long-acting OCs have proved to be very effective, and the rate of breast cancer and cervical cancer is lower than the normal rate. The childbearing ability can be restored rapidly after discontinued use of the contraceptives. The impact on menses and metaboliism is not very serious. The health of the users and the newborn babies has not been found to be endangered. Statistics show that long-acting OCs are comparatively more secure measures for birth control; 2) some users have experienced dizziness, nausea, and excessive leukorrhea, and discontdiscontinued because of discomfort and inconvenience. This situation has some impact on the popular use of long-acting OCs. Research and studies are underway on a reduced dosage and reduction of side effects; 3) women who suffer from hepatitis, nephritis, a history of liver and kidney problems, breast tumors, cervical cancer, diabetes, active low blood sugar, or a history of having over-sized babies, or an overweight problem should not use OCs. Women who suffer from high blood pressure can only use OCs with a doctor's advice and caution.

This review concerns the present state of accomplishments in the study of SEM of human and experimental renal disease. Critical techniques of specimen preparation reviewed include perfusion fixation, razor tissue sectioning, alcohol cryofracture, microtome sectioning of paraffin or styrene embedded tissue, ultraplaning with glass knives of hard carbowax embedded tissues and glomerular isolation. Gold-palladium coating and heavy metal impregnation with osmium, uranium, and silver are discussed. A compendium of SEM observations of human glomerular, vascular and tubular disease is presented. Techniques for SEM of experimental renal disease are reviewed. These include latex vascular injection, freeze drying, x-ray microanalysis and use of backscattered electron imaging. Experimental models previously investigated by SEM are puromycin aminonucleoside nephrosis, daunomycin nephrosis, and N,N1-Diacetylbenzedine glomerulopathy, nephrotoxic serum nephritis, and protamine perfusion glomerulopathy. Reviewed are acute tubular necrosis caused either by angiotensin, hypotension, norepinephrine, glycerol, mercury, and unilateral renal artery occlusion, also potassium depletion nephropathy, alloxan diabetes and diphenylamine-induced polycystic disease.

The results of 2 studies to determine the relationship between hormonal contraceptive (h.c.) use, hypertension, and nephritis are reported. 828 women, 16-50 years of age, were divided into 3 groups. 1 group had never used h.c.s., 1 group was presently using h.c.s., and 1 group had used h.c.s. for the last time more than a year prior to the study. Women 26-35 years of age who were using h.c.s. at the time of the study more often developed hypertension than other groups. The h.c. users who developed hypertension more often had a family history of hypertension or diabetes mellitus, more often had diabetes themselves, and more often suffered from preeclampsia or eclampsia during pregnancy. In a second study, ethinyl estradiol, norethisterone acetate, epsilon aminocapronic acid, desoxycorticosterone acetate, and table salt were administered singly or in combinations to 2 groups of rats. In one group, a Goldblatt-type hypertension was induced with a clamp on the nephric artery. No increase in blood pressure was observed in animals which received only an estrogenic or progestagenic agent. Significant increases in blood pressure were observed in animals that were given combinations of estrogenic and progestagenic agents, however. Significantly increased plasma-resin activity was observed in all animals which were given estrogen, while animals receiving desoxycorticosterone acetate showed a highly significant decrease in plasma-renin activity.

Although the nature of firefighting involves particular health hazards, previous mortality and morbidity studies of firemen have produced inconsistent evidence for an increased risk of mortality from cardiovascular disease, respiratory disease, cancer and accidents. Mortality experience since 1915 has been examined in 5655 Boston firefighters, comprising all male members of the city fire department with three or more years of service. The observed cause of death as stated on the death certificates of 2470 deceased firefighters has been compared with the numbers expected based on rates for the male population of Massachusetts and of the United States of America. Among all firefighters, deaths from all causes were 91% of expected. The standardised mortality ratio (SMR) was markedly reduced (less than 50) for infectious disease, diabetes, rheumatic heart disease, chronic nephritis, blood diseases and suicide. The SMR was 86 for cardiovascular deaths, 83 for neoplastic deaths, and 93 for respiratory deaths. The SMR for accidents was 135 for active firefighters. The results suggest that the survival experience of firefighters is strongly influenced by strict entry selection procedures, ethnic derivation, and sociocultural attributes of membership. While excessive morbidity has been demonstrated in firefighters, there does not appear to be a strong association between occupation and cause-specific mortality.

The results of kidney transplantation in a variety of renal diseases have been analyzed. The diseases causing end-stage kidney failure in recipients were Alport syndrome, amyloidosis, cystinosis, diabetes mellitus, Fabry disease, familial nephritis, gout, medullary cystic disease, oxalosis, and systemic lupus erythematosus. The data indicate that renal transplantation is justifiable and parallels functional results for the more common causes of end-stage renal disease in all but Fabry disease and oxalosis. Although Fabry disease did not recur in any grafted kidney, only three patients have a functioning graft one year after transplantation. From a group of ten patients with oxalosis who received a total of 14 kidneys, only one survives. In no other metabolic disease, except one instance of primary amyloidosis, did the metabolic disease notably affect the transplant as it did in oxalosis.

Most adults with acute bacterial renal infection demonstrate no roentgen abnormality in the acute stage and recuperate without significant functional or morphological renal abnormality. We report the initial and long-term findings in a virulent form of acute bacterial nephritis caused by gram-negative organisms and predominantly in patients with diabetes and associated septicemia. The findings of a small, poorly functioning symmetrically scarred kidney with significant caliceal distortion and the associated angiographic abnormalities are presented for the first time in the long-term followup of this disease.

Small cutaneous vessels, obtained by ear lobe biopsies, were studied in 14 patients with various chronic nephritides and in 10 normal controls. The capillaries in the group of patients with nephritis were found to undergo two main changes: thickening of the adventitia reticularis and perivascular cellular infiltration in an inverse ratio. This infiltration was seen to be made up of mononuclear cells and an increased number of mast cells in various stages of degranulation. Changes in the basement membrane as seen by electron microscopy are not constant. All of the above changes were absent in the controls and are similar to what has been described in previous studies in both experimental and spontaneous pathologic conditions, such as experimental hypertension, diabetes mellitus, scleroderma, rheumatoid arthritis, etc. Small vessel involvement in chronic nephritides could be part of a process of diffuse microvascular damage that includes the kidneys or it may be related to hypertension or to the biochemical changes which follow uremic and pre-uremic states.
