A series of 106 cases of polycystic kidneys in adults is presented. The main clinical, exploratory and therapeutic data are analyzed. The average age of the patients at the time of the first clinical manifestation was 35 years; average age at the time of diagnosis was 43 years. The most common forms of presentation included renal colics, blood
hypertension
, noncolic lumbar pain, macroscopic hematuria, and polydipsia-polyuria. The most frequent symptoms were: abdominal pain of any type (73 patients), polydipsia-polyuria (66 patients), blood
hypertension
(61 patients), macroscopic hematuria (47 cases), episodes of urinary infection (41 cases), and passing of calculi (22 cases). Seventy-eight subjects had arterial
high blood pressure
; it was easily controlled in all except 14 cases. Proteinuria was slight in all except two cases. Values for hematocrit and hemoglobin remained high in relation to the degree of renal insufficiency. The mean value of hematocrit in patients with creatinine clearance below 10 ml/min was 30 percent. Renal function decreased gradually, from normal to a clearance of less than 10 ml/min over a period of 12 years on the average. Diagnosis was based mainly on abdominal physical examination and intravenous urography; 89 patients had palpable abdominal masses. Urography revealed typical images of polycystic kidney in every case. The following associated conditions were also discovered: liver cysts (17 cases among 57 liver scanning; bilateral
ovarian cysts
in one case; Cacci-Ricci's disease in one case; and cerebral arterial aneurysms in another patient. Treatment was conservative with the aim to control arterial blood pressure and urinary infection. Twenty-nine patients required saline replacement; peritoneal dialysis was practiced in two cases and permanent hemodialysis was prescribed for 15 individuals.

Of the oral contraceptives in current use, the most practical and effective are: 1) the combination pill (estrogen and progesterone in various combinations), with a contraceptive effect of almost 100%; 2) 2-phase treatment (estrogen and progesterone administered sequentially), which produces less negative side effects, but is slightly less reliable as an ovulation inhibitor; and 3) the minipill (containing only progesterone), which eliminates any estrogen-induced side effects, but is slightly more complicated as a medication. Continuous treatment with large combination dosages may be tried when complete elimination of menstruation is desirable. The monthly and weekly pills are still being tested. High dosages before or after coitus may be used in certain situations. Clinically undesirable side effects of oral contraceptives include urinary tract infections, fluor vaginalis, moniliasis,
hypertension
, water retention, lactation changes, and, less frequently, liver and skin disorders and modifications of the carbohydrate metabolism system. These can often be lessened or eliminated by changing to the minipill or to another preparation. A table indicates signs of excessive estrogen or progesterone influence. Extremely serious (sometimes life-threatening) side effects include persistent anovulation, thromboembolic disorders, liver tumors, and severe
hypertension
. Often the beneficial side effects of oral contraceptives are not mentioned, e.g., improvement or elimination of menstrual disorders, anemia, and acne, and prevention of benign breast and uterine tumors and
ovarian cysts
. The psychological benefits must also be taken into account. Fear of pregnancy is eliminated and birth control spacing results in improved health for mothers and children.

Types of oral contraceptives, their mode of action, choice of dosage, side effects, and contraindications are summarized for the general clinician. A 50 mcg dosage of estrogen in a combination formula appears to be the minimum dose necessary for consistent protection from pregnancy although some compounds with less estrogen but a more powerful progestin appear to provide good protection. These lower dose estrogen formulations may be advised if estrogen-related symptoms such as nausea or breast soreness are encountered. In amenorrheao r symptoms of estrogen deprivation 80-100 mcgs of estrogen may be required. Although there is a risk of thromboembolic disease,
hypertension
, carbohydrate and lipid metabolic effects, gallbladder disease, hepatoma, and possible post-pill amenorrhea, these problems can be minimized by careful screening of patients. Benefits include decreased incidence of
ovarian cysts
, benign breast neoplasia, menstrual disorders, premenstrual syndrome, iron deficiency anemia, sebaceous cysts, and acne (due to decreased sebum production with estrogen adminsitration). Patients need to be reminded that the morbidity and mortality associated with pregnancy exceed that attributed to oral contraceptives.

The beneficial effects of combined estrogen-progestin-containing oral contraceptives (OCs) include prevention of pregnancy (less than 1 failure out of 100 regular users); the prevention of ectopic pregnancy; the reduction of preeclampsia (2.4 times lower risk compared with barrier methods); and reduction of pelvic inflammation to about one-half. The effects on menstruation include the reduction of sideropenic anemia (by lowering the incidence and duration of menstruation, OCs reduce the loss of iron to 50% or to as much as 33%); dysmenorrhea by 40% (symptoms receded in 90% of users); and premenstrual syndrome by 30%. OCs exert a favorable effect on menstrual epilepsy; reduce sports-related accidents in the premenstrual and menstrual periods; and reduce intermenstrual bleeding. The protection from cancer includes the lowering of endometrial cancer risk (every 2 years of use reduces the risk by 38%, 12 years of use by 70%, and the beneficial effects last 3-15 years); reduction of the risk of the ovarian cancer (already 3-6 months of use reduces the risk by 30%, and more than 5 years by 50% in women under 50 years of age with a longterm effect of 10 years or more, which drops sharply in women over 60 who are mostly at risk). Among other beneficial effects, they reduce benign mastopathy by 50-75%; reduce the risk of follicular
ovarian cysts
to 50% and the risk of corpus luteal
ovarian cysts
to 1/5; and they lessen bone loss which favorably affects osteoporosis. Low-dose OCs minimize the well-known risks of thrombotic and cerebrovascular accidents, myocardial infarction,
hypertension
, altered carbohydrate metabolism, gallbladder diseases, and liver cancer. A new OC with 30 mcg of ethinyl estradiol was tested with daily doses of 150 mcg of desogestrel. The high density lipoprotein (HDL) either increased or did not change with desogestrel: the HDL2 subfraction that protects from atherosclerosis did not change, and probably the HDL3 raised the HDL level.

The overall risk of oral contraceptive (OC) use is minimal when women over 35 years of age, smokers, and those with multiple risk factors (thromboembolic disorders, cerebrovascular or coronary artery disease, liver tumors, breast cancer, estrogen-dependent neoplasms, undiagnosed abnormal genital bleeding, and congenital hyperlipidemia) are excluded. OC use increases the risk of
hypertension
by 1-5%, depending on age, parity, and duration of use, but even this small risk is decreased when multiphasic OCs are prescribed. Deep venous thrombosis in the leg is 4 times more prevalent in OC users than nonusers and the risk of superficial thrombosis is doubled. Again, fewer thromboembolic complications occur when the estrogen dosage is low. The risk of myocardial infarction is not believed to increase with OC use as long as other risk factors--smoking, obesity,
hypertension
, age over 35 years, hypercholesterolemia--are not present. Studies involving the original high-dose OCs revealed a 3-fold increase in the risk of thrombotic stroke and a 2-fold increase in the risk of hemorrhagic stroke, but low-dose OCs appear to have no effect on the potential for stroke. The impact of OC use on breast cancer cannot yet be determined given the very long latency period of this cancer. In terms of benign breast disease, OC users have been shown to be at substantially reduced risk of lesions, fibroadenomas, and fibrocystic changes. OCs also protect women from endometrial and ovarian cancer, although the pill seems to accelerate the progression of cervical dysplasia. Other beneficial effects of OC use include reductions in the incidence of pelvic inflammatory disease, endometriosis, ectopic pregnancy, and
ovarian cysts
.

Like all drugs, combined oral contraceptives (COCs) have side effects that may be harmful or beneficial. During the last 20 years their adverse effects have been fully reported, but their benefits have been largely ignored. Most of the benefits of COCs result from the suppression of ovulation. This means that the advantages they confer are not dose-dependent, provided that ovarian activity is effectively suppressed. The most important health benefit of COCs worldwide is the effective prevention of pregnancy, which carries high risks in developing countries and has a mortality as high as 1 in 150 in Africa. The risk of ectopic pregnancy is reduced by 90% in COC-users compared with women using no contraception. The COC prevents the repeated proliferation of ovarian and endometrial tissue that takes place in the menstrual cycle, and it is therefore not surprising that it reduces the risk of ovarian and endometrial malignancy. What is surprising is that a relative risk of 0.6 for these cancers can be detected after only 12 months or less of COC use, and persists for at least 15 years after the COC is stopped. The COC reduces the incidence of benign breast disease, though not the types of disease linked with breast cancer. It considerably reduces the incidence of benign
ovarian cysts
, and this has been calculated to avoid 28 operations for functional
ovarian cysts
per 100,000 pill users every year. The risk of uterine fibroids is reduced by 17% with every five years of COC use. By thickening the cervical mucus, the COC reduces the risk of pelvic inflammatory disease by about 50%. By inhibiting growth and development of the endometrium it reduces the incidence of menorrhagia and consequently iron-deficiency anaemia, and it produces a 40% reduction in the frequency of dysmenorrhoea. Unlike the benefits of the COC, its risks appear to be to some extent dose-dependent. The first serious risk to be discovered was a three- to six-fold increase in venous thromboembolism, which is probably an oestrogen effect and disappears quickly when the COC is stopped. The COC doubles the risk of haemorrhagic stroke, this risk is related to smoking and
hypertension
, unlike the increased risk of thrombotic stroke. The risk of myocardial infarction is related to smoking and age, and COCs are contraindicated over the age of 35 in smokers though not necessarily in non-smokers. Much of this information, however, is based on studies involving older high-dose COCs. Risks may well be lower with modern COCs, but firm data are lacking.(ABSTRACT TRUNCATED AT 400 WORDS)

Autonomic dysreflexia may present itself as a medical emergency in quadriplegics and paraplegics above the T6 level. Common causes are bladder/bowel dysfunction and pressure ulcers. A case study is presented in which an
ovarian cyst
was the cause of autonomic dysreflexia. Excision of the
ovarian cyst
stopped recurrence of paroxysmal
hypertension
and completely alleviated signs and symptoms of autonomic dysreflexia.

This guide to choice of oral contraceptives, for U.S. clinicians, includes a review of the available types of pills, the pharmacology of the steroids in pills, safety issues regarding thrombosis, arterial disease and
hypertension
related to estrogens and progestins in pills, common side effects, and therapeutic uses of orals. Choice of an oral contraceptive narrows down to which of the 5 available progestins and their formulation, since all contain ethinyl estradiol as the estrogen. While Briggs' theory espoused picking a pill with the minimal metabolic effect, recent evidence suggests that some estrogenic activity may be preferable to the unopposed progestagen, actually an anti-estrogenic receptor effect, to prevent adverse lipid and blood pressure effects in users. Current pills with low doses of estrogens probably are not significant risks for women as regards thrombosis, particularly if predisposed women and smokers are excluded. Pills containing 0.35 mg ethinyl estradiol and 0.5 mg norethindrone, based on large population trials, are probably the minimal effective dose yet even these are more effective than most other contraceptive methods. Breakthrough bleeding and spotting have been further minimized, however, with multiphasic pills. It is best to start with a 0.30-0.35 mg estrogen oral contraceptive, such as Loestrin, Demulin, Orthonovum 1.35, Orthonovum 7/7/7 or Nordette, encouraging the patient to accept early side effects for 3 months before switching to others. Disorders that can be managed with oral contraceptives include recurring and pre-existing
ovarian cysts
, endometriosis, dysfunctional uterine bleeding and dysmenorrhea. Brief guidelines for handling normal side effects and treatment of the above disorders are included.

This artical examines the risks and benefits associated with use of the oral contraceptive pill (OCP) by adolescents and the various alternatives and methods of prescribing OCPs. Any adolescent who is either sexually active or contemplating sexual activity should be offered a contraceptive method that is appropriate to her individual needs. The contraceptive needs to be highly effective, safe and within the means and desires of the adolescent. For the majority of teenagers, the contraceptive of choice will be the OCP. The IUD should almost never be prescribed to the adolescent. Most OCPs marketed today are combination pills containing both an estrogen and a progestin in each pill. A variety of contraceptive actions combines to create a contraceptive method that is 99.3-99.9% effective. OCPs provide some protection against the development of pelvic inflammatory disease (PID). Oral contraceptives also decrease the incidence of anemia by decreasing the amount and duration of menstrual flow.
Ovarian cysts
do not form in the ovaries of the OCP user. On the other hand, a serious risk of the use of OCPs is the increased danger of thromboembolic events including deep venous thrombosis, pulmonary embolus, and myocardial infarction. The increased risk of myocardial infarction in OCP users is additive with other risk factors including
hypertension
, hypercholesterolemia, cigarette smoking, obesity, diabetes mellitus, and age. OCP use seems to provide some protection against development of endometrial or ovarian cancer. Oral contraceptives are associated with the development of benign hepatocellular adenomas. A variety of metabolic and hormonal alterations also occur in pill users. Most appropriate for the adolescent is a formulation containing a low dose of estrogen because of the decreased risk of thromboembolic complications. Dysmenorrhea effects more than 1/2 of female adolescents, and can best be treated with ibuprofen.

During the 20 years since the oral contraceptive was introduced, it has been used by some 150 million women around the world, and is perhaps the most carefully monitored medication in history. This vast body of research shows that for the overwhelming majority of healthy women under 30, the benefits of the pill continue to outweigh the risks. The most serious life threatening risks are those involving the cardiovascular system: heart attack, stroke, and throboembolism. However, deaths from these causes would be reduced by 1/2 if women using the pill did not smoke; further reductions would result if women with
high blood pressure
, high chloresterol levels and diabetes millitus did not use the pill. There is no evidence thus far to justify fears that the pill might be associated with an increased risk of cancer. Most studies show that not only is there no association between pill use and cancer of the ovaries, uterus and breast, but pill use may protect against ovarian and endometrial cancer. Women taking the pill are 1/4 as likely to develop benign breast lumps as nonusers, 1/14 as likely to develop
ovarian cysts
, 2/3 as likely to develop iron deficiency anemia, and 1/2 as likely to develop rheumatoid arthritis -- all relatively common conditions. In addition, pelvic inflammatory disease, a major cause of infertility, appears to occur only 1/2 as often among pill users as among nonusers. The risk to life among pill users younger than 30 who do not smoke is very small (virtually the same as that of users of the IUD, diaphragm, or condom) and is much lower than the risk of birth-related deaths among women who use no birth control.
