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.

The contents of this paper are divided into three parts: the first points to the health risk for the dentist and his patients which has only been recently recognised to its full extent and seriousness: the transmission of virus hepatitis during dental treatment. The second section tries to enrol the help of oral surgery to detect the large number of unrecognised cases of hypertension through the introduction of blood pressure measurement into dental practice. The subject of the third section is the problem patients and patient problems deriving from medical diseases which crop up almost daily in dental practice and which should lead to interdisciplinary consultation between oral surgery and internal medicine.

A 59-year-old woman was admitted to the hospital for evaluation of her hypertension. She was treated with hydralazine; two days later a severe acute hepatitis supervened. On discontinuation of the agent, the liver damage disappeared, relapsed during inadvertent rechallenge, and healed following permanent withdrawal from the drug. Histologic study of the liver showed severe acute hepatitis with bridging necrosis (so-called subacute hepatitis). Six months after discontinuation of hydralazine, a second liver biopsy specimen showed a complete remission of the disease. This hydralazine-induced hepatitis appears to be fully reversible and to differ both on clinical and histological grounds from two previous reports documenting a granulomatous liver disease.

Classical sex-linked hemophilia (Hemophilia A) has been described as due to deficiency in the synthesis of Factor VIII procoagulant activity (VIII:C). The availability of immunological techniques provided the means of identifying Factor VIII-Related Antigen(VI-IIR:Ag) detectable by rabbit antibodies to F VIII, which is distinct from VIII:C detected by human anti-F VIII available from multitransfused patients. Hemophilia A is lacking in VIII:C but not VIIIR:Ag. Recently, a third function of the F VIII "complex" was discovered with the help of ristocetin (von Willebrand's Factor, VIIIR: RCo). This activity is reduced in von Willebrand's syndrome. Estimation of the titers of VIII:C and VIIIR:Ag provides a method for more accurate detection of hemophilic carriers. Newly available chromogenic substrates perhaps will give rise to more simplified assays of VIII:C. The development of cryoprecipitates and stable lyophilized concentrates of F VIII has greatly simplified and intensified maintenance therapy, and has opened a new era in treatment. Prophylactic therapy has been shown to be very helpful in certain "high risk" cases. The impact and benefits of home care and self-administration has been tremendous. However, the varying quality of cryoprecipitates and the high cost of more purified concentrates are still stumbling blocks in treatment regimes. Other problems exist. Spontaneous bleeding, especially central nervous system bleeding, account for the majority deaths by haemorrhage. Inhibitor kinetics have been well characterized. It is clear that there exists "low" and "high" responders. For the "high" responders, plasmapheresis, immunosuppressives and the infusion of Factor IX concentrates have been utilized with varying success. The prevention of hemophilic arthropathy and its progression by maintenance therapy seems to be still inadequate. The results of trials with more vigorous regimes are awaited. The complications of therapy still remain to be solved. Apart from the well-known complications wuch as hepatitis, haemolytic disease and F VIII inhibitors, the existence of previously unnoticed complications as splenomegaly, hypertension, renal disease and paradoxal bleeding have been recently realized. The role of altered fibrinogen, fibrin degradation products (FDP) and unclassified fibrinogen derivatives (UFD) present in cryoprecipitates and F VIII concentrates in the above complications needs to be further clarified. In conclusion, tremendous progress in various aspects of hemophilia has been achieved in developed countries. Comprehensive care can now be carried out in various centers. On the other hand, developing countries still face a number of basic problems. The concept that hemophilia is a "manageable" disease and that chronic crippling and death from exsanguination can be prevented, should be disseminated widely by various means...

The efficacy of correlating the L/S ratio in the amniotic fluid with fetal lung maturity has been substantiated in normal pregnancies. In gestations complicated by fetomaternal diseases, however, the assay is less reliable. This study involves 555 pregnancies in which there was a significant maternal, fetal, or placental disorder. The L/S ratio was related to fetal respiratory maturity as measured by Dubowitz criteria and the occurrence of RDS. The results show that pre-eclampsia, chronic hypertension, diabetes (Class D, E, F), significant cardiovascular disease, severe hemoglobinopathies, various congenital anomalies, chronic placental insufficiency, and prolonged ruptured membranes accelerated the L/S ration. Conversely, mild diabetes (Class B, C), intrinsic renal disease, hepatitis, collagen disease, hydrops fetalis, syphilis, and toxoplasmosis were associated with a delay in the L/S ratio. A significant increase in erroneous responses was noted in these patients when the L/S ratio was correlated to infant maturity and to the incidence of RDS. Possible mechanisms for these findings are discussed.

Five patients with hypertension died as a result of myocarditis. Three were treated with methyldopa and hydrochlorothiazide, two with methyldopa alone. Their ages ranged from 30 to 71 years. In all instances death occurred suddenly, and myocarditis was not suspected clinically. The inflammatory changes in the hearts of these patients were most consistent with a hypersensitivity reaction. Additionally, there was hepatitis consistent with hypersensitivity in four of the cases.

The causes of disqualification in a volunteer blood donor population for a period of two years were analyzed. Of 138,436 prospective volunteer blood donors, 24,327 (17.6%) donors were disqualified. Phlebotomy was unsuccesful in 721 (0.5%) donors and blood was drawn from 113,388 (81.9%) eligible donors. The majority of rejections were due to medical history findings (61.0% of all rejections). The ten leading causes of disqualification were: low hemoglobin/hematocrit, medication, allergies, signs and symptoms, high blood pressure, illness in last month, hepatitis and hepatitis exposure, malaria and travel overseas, atypical antibodies, and high serum bilirubin. Hepatitis B surface antigen was detected in 82 donors out of 114.746 donors tested (0.07%).

A 55-year-old woman developed symptoms suggestive of hepatitis 12 weeks after first receiving methyldopa for hypertension. Liver biopsy showed chronic aggressive hepatitis with subacute hepatic necrosis. Methyldopa was discontinued, but after exhibiting transient clinical improvement, the patient's condition progressively deteriorated until she died of hepatic failure, in spite of therapy with massive doses of corticosteroids and other nonspecific measures. During the terminal stage, a considerable decrease in the size of the liver was observed. At autopsy, the liver was found to be small, shrunken, and scarred; histological sections demonstrated postnecrotic cirrhosis. Such a rapid and relentless progression of methyldopa-induced liver injury is undoubtedly rare, but it may be prevented by careful supervision of patients who exhibit liver function abnormalities early in the course of therapy.

This study attempts to collect reliable data on maternal deaths, estimate maternal mortality rate for the western state of Nigeria, and identify major causes of maternal deaths in the state. Standardized questionnaires were sent to randomly selected medical institutions (5 specialist hospitals and 25 general/district hospitals) in the state; only 23 institutions (4 specialist and 19 district/general hospitals) completed the questionnaires. The results show that maternal mortality ranged from 0/1000-13.3/1000 total births in 1972 and 0/1000-11.0/1000 total births in 1973; overall maternal mortality rate was 3.8/1000 in 1972 and 4.7/1000 in 1973. Mortality was higher among unbooked patients, accounting for 71.2% and 66.4% of total deaths in 1972 and 1973. Hemorrhage (antepartum and postpartum), obstructed labor (uterus unruptured and ruptured), eclampsia and anemia of pregnancy accounted for over 80% of total deaths. Nonobstetric causes of maternal deaths including poisoning, infective hepatitis, meningitis, encephalitis, bronchial asthma, hypertension, and pulmonary embolism. The major causes of death in this series were preventable. Maternal mortality is associated with age, parity, and past reproductive and medical history. The high maternal death rate in this study is compounded by nonutilization of available medical services by pregnant women most especially for antenatal care, the lack of basic essential life-saving facilities (e.g., for blood transfusion), lack of adequate transportation system, failure of medical/nursing personnel to refer patients early to specialist hospitals, and relative lack of obstetric services both in quality and quantity all over the country. Better coordination and integration of health services are needed, as are nationwide data collection of maternal death statistics, publication of periodical reports, and establishment of standards for overall maternity care.

The vasculitis nodularis belongs to the group of the allergic-hyperergic vascular diseases of the skin, which above all the small veins are affected at. The participation of internal organs is unusual. It is reported on a 31-year-old Syrian patient in whom a participation of the liver in form of a granulomatous hepatitis and of the kidneys appeared. A hypertension might be attributed to the participation of the kidneys. The incorporation of a thrombosis of the central vein of the right eye in this disease is probable. The main symptoms of the disease were nodes of the size of a bean occurring in batches, lying subcutaneously, and were paraclinical signs for inflammation. The permanently increased absorption-antistreptolysin titre spoke for an allergic-hyperergic vascular process induced by streptococci.
