Multicystic dysplastic kidney is the most frequent cause of an abdominal mass in the neonate, but controversy continues as to the optimal management of these lesions, since little is known about their natural history. Experience with two complicated cases and a review of reports of retained multicystic dysplastic kidneys suggest that such lesions pose a significant risk to their hosts. Malignancy, reversible hypertension, pain, and mass effect have been associated with retained lesions. Infection is another potential hazard that is frequently cited but poorly documented in the literature. In light of the currently low morbidity and mortality associated with operation and anesthesia in the neonatal period, resection appears to be the treatment of choice for the neonate with a multicystic dysplastic kidney.

A multitude of general disorders of the vascular system may also affect the blood circulation of the cochlea and cause symptoms such as fluctuating or permanent hearing loss. Such is the case for arteriosclerosis combined with hypertension or hypotension, collagenosis, and diabetes. Blood disorders, like leukemia, sickle cell anemia, and polycythemia, and infectious diseases involving the blood vessels, such as lues, may also present their primary symptoms in the ear. The otorhinolaryngologist must be able to establish the correct diagnosis and refer patients requiring more general treatment to other specialists. The use of specific vasoactive treatment should be continued to those patients with symptoms of acute or fluctuating hearing loss, vertigo, or tinnitus who exhibit no other signs. Modern techniques for cochlear blood flow measurements have verified that several of the treatment protocols in use, which have a sound theoretical background, do indeed increase cochlear blood flow.

During a 10-year period vascular access in 86 patients receiving long-term haemodialysis was provided by the insertion of 100 polytetrafluoroethylene grafts. In 24 patients (28%) the PTFE prosthesis was used as a primary access operation; 62 patients (72%) had had previous access procedures. Early thrombosis and infection led to graft failure in eight patients. Late fistula occlusion developed in 67 instances in 39 fistulae. Thrombectomies were performed in 53 fistulae with good result in 46 (86.8%). Infection after puncture was seen in nine grafts and was treated by incision and drainage (33%) or graft removal (67%). False aneurysms developed in six patients; prolonged haemorrhage from the puncture site occurred in one patient and haemodynamic complications (ischaemic steal syndrome; venous hypertension) developed in four. The cumulative patency of PTFE AV fistulae was 74% after 1 year; 59% after 2 and 3 years and 47% after a follow-up of 5 years. Despite the high rate of complications the PTFE AV fistula has proved an acceptable technique in secondary access surgery for haemodialysis.

A total of 850 cases of septic diabetic foot infections were reviewed in 355 patients. Age, sex, other chronic diseases, site, etiology, Wagner grade, treatment, and results were analyzed. One third of the patients were in their sixth decade of life. There were 180 women and 175 men. Chronic diseases included hypertension, congestive heart disease, and renal failure. Staphylococcus aureus was the most common bacteria. Treatment was considered to meet protocol standards if Wagner's algorithms and infectious disease principles were followed. Thirty-nine Wagner grade 0 infections were seen: only one was not treated appropriately. Eighty-eight percent treated per protocol healed and the one not treated appropriately failed. In grade 1, 79% of the 154 evaluable patients were treated appropriately with a 86% success rate versus a 53% success rate for those not treated per protocol. Of three quarters of the 64 patients with grade 2 infections treated according to protocol, 73% healed. One of those in grade 2 who was not treated according to protocol healed. In grade 3, 64% of the 251 patients were treated per protocol with a 79% success rate versus a 12% success rate for those who were not treated per protocol. Most of the 189 patients with grade 4 cases were treated according to protocol with 88% success; the 20 not treated per protocol had a 15% success rate. Thirty of the 32 grade 5 patients were treated per protocol and all but one healed. Protocol therapy had a statistically significant effect by chi 2 test in the treatment of all groups.

Kidney infection, when uncomplicated by anatomic abnormalities such as reflux or obstructing lesions, does not appear to lead to renal damage or hypertension. In children in whom predisposing anatomic causes (reflux) are particularly prominent or in adults who have or develop these abnormalities, progressive renal injury with hypertension can occur with infection. Infection appears to enhance the damaging effects of the underlying anatomic abnormalities. The mechanisms of progressive damage include the inflammatory effects of the infection itself, potentially "autoimmune" effects, and the inflammatory and infection-promoting effects of bacterial products, especially ammonia. After initial renal damage, the hemodynamic effects of systemic hypertension and of intrarenal hyperperfusion of residual nephrons may further promote progressive injury.

Garlic may play an invaluable role in the prevention and therapy of the major causes of death. Anecdotal, basic, and clinical research data are confirming the efficacy of this herb in the treatment of hyperlipemia, cancer, heavy-metal intoxication, infectious diseases, hypertension, free-radical damage, and immune deficiency states. Garlic's broad antimicrobial spectra and its ability to modulate immunity may play a strategic role in the acquired immunodeficiency syndrome pandemic. A review of the literature supports a greater scrutiny of this herb's therapeutic potential.

Since the introduction of new non-invasive diagnostic techniques such as abdominal ultrasound and computerized tomography, simple renal cysts are diagnosed with increasing frequency. Over 30% of patients over 50 years of age are found to have simple renal cysts of different size. A cystic renal mass may represent a simple renal cyst without clinical relevance, a cystic renal carcinoma, early evidence of polycystic kidney disease in a young patient, a rare cause of renal hypertension, a source of infection in a symptomatic patient (infected renal cyst), or a manifestation of an infectious disease (renal abscess, echinococcus cyst). The differential diagnosis and management of a cystic renal mass therefore remain a clinical problem. In the past, surgical exploration of a cystic renal mass was frequently performed. Today, modern diagnostic techniques such as ultrasound-guided percutaneous cyst puncture with cytological analysis of the cyst content, or computerized tomography, are considered the methods of choice. They are particularly useful in case of doubt about the dignity of a cystic renal mass. The determination of renal venous renin levels may be useful in differentiating the causal role of a renal cyst in a patient with hypertension. The management of a cystic renal mass depends on the underlying disease.

Ethiopia is a country of 45 million people in northeast Africa. With a stagnant, agriculture-based economy and a per capita gross national product of $110 in 1984, it is one of the world's poorest nations. 70% of the children are mildly to severely malnourished, and 25.7% of children born alive die before the age of 5. Life expectancy is 41 years. The population is growing at the rate of 2.9%/year, but only 2% of the people use birth control. After the 1974 revolution, the socialist government nationalized land and created 20,000 peasant associations and kebeles (urban dwellers' associations), which are the units of local government. The government has set ambitious goals for development in all sectors, including health, but famine, near famine, forced resettlement programs, and civil war have prevented any real progress from being made. The government's approach to health care is based on an emphasis on primary health care and expansion of rural health services, but the Ministry of Health is allocated only 3.5% of the national budget. Ethiopia has 3 medical schools -- at Addis Ababa, Gondar, and the Jimma Institute of Health Sciences. Physicians are government employees but also engage in private practice. A major problem is that a large proportion of medical graduates emigrate. Ethiopia has 87 hospitals with 11,296 beds, which comes to 1 bed per 3734 people. There are 1949 health stations and 141 health centers, but many have no physician, and attrition among health workers is high due to lack of ministerial support. Health care is often dispensed legally or illegally by pharmacists. Overall, there is 1 physician for 57,876 people, but in the southwest and west central Ethiopia 1 physician serves between 200,000 and 300,000 people. In rural areas, where 90% of the population lives, 85% live at least 3 days by foot from a rural health unit. Immunization of 1-year olds against tuberculosis, diphtheria-pertussis-tetanus, poliomyelitis, and measles is 11, 6, 6, and 12% respectively. Infectious diseases dominate the medical scene in Ethiopia. In 1984, tuberculosis accounted for 11.2% of hospital admissions and 12.2% of deaths. The leading cause of childhood mortality in 1984 was diarrhea (45%). Malaria, trypanosomiasis, schistosomiasis, leishmaniasis, and meningococcal meningitis are endemic. Intestinal parasitism is rampant, and the nationwide prevalence of leprosy is 3/1000. Venereal diseases were the 9th most common cause of hospital outpatient visits in 1984, but AIDS is rare. The leading noninfectious diseases are rheumatic and syphilitic heart disease, hypertension, diabetes mellitus, hepatoma, and elephantiasis. Ethiopia has the highest number of cases of nonfilarial elephantiasis -- an estimated 350,000 cases -- in the world. Aside from a large influx of money, the most necessary changes to improve the health system are lowering the salaries of doctors and nurses, reorienting physician training toward primary health care, increasing the quality of existing health services, more efficient management, and better coordination between the Ministry of Health and the voluntary organizations.

Within a 2 month period 131 Ethiopian immigrants were admitted for treatment at a general hospital in Jerusalem. There were 52 patients with malaria, 13 with typhoid fever, 24 with pneumonia, seven with tuberculosis, nine with shigella and 11 with campylobacter. Over three-quarters of these patients were anaemic. In the majority of cases anaemia was normocytic and was most probably secondary to malaria and other intercurrent infections. The prevalence of diffuse non-toxic goitre was 7% in children and 19% in adults with a male to female ratio of 4:13. A positive rapid plasma reagin (RPR) test was found in 4% of sera tested and a positive HBsAg in 13%. IgG antibodies to HBc antigen were found in 75% of subjects. All patients with infectious diseases responded to therapy and, despite their poor condition at arrival, there were no fatalities and no late sequelae. The high HBsAg carrier state calls attention to the risk of vertical transmission by infected mothers and underlines the need for active immunization of infants at risk. The high prevalence of untreated tuberculosis and malaria poses a potential public health hazard, but with the current systematic screening of this population leading to identification and effective treatment of affected subjects, chances for the practical eradication of malaria and tuberculosis are excellent. Finally, the large scale transfer of a population from rural Africa to a modern and largely urban society presents a unique opportunity for a prospective study of the impact of environment on the emergence of diseases which plague modern society such as diabetes, atherosclerotic cardiovascular disease, hypertension and cancer.

As a result of decreases in maternal mortality and infectious diseases, women's life expectancy has increased rapidly in this century and is expected to reach 83 years by the year 2000. However, there are a large number of chronic conditions that negatively affect the quality of life of women today: urinary tract infection, menstrual cycle disorders, hypertension, diabetes, osteoporosis, arthritis, eating disorders, substance abuse, and mental depression. Although women's life expectancy is 7.5 years greater than that of men, the morbidity rates are significantly higher for women. As women continue to enter the labor force in large numbers, questions are being raised regarding the physical and psychological hazards of jobs traditionally considered to be women's work, the risks associated with jobs that are physically demanding or involve exposure to toxic substances, and the association between pregnancy outcome and employment. Further research is needed on the effects of multiple role stress on women's health. Another recent trend has been the feminization of poverty: 2/3 of all US adults classified as poor are women. The lack of financial resources has a detrimental effect on nutrition, access to health care, and other preventive behaviors. Yet another social change related to women's health is the increasing number of elderly in the population. Women comprise 72% of the elderly poor, and over 80% of all retiring female workers do not have pension benefits. Access to, availability of, and payment for health care are problems for elderly women. It is important that research address the physiologic, psychosocial, and economic factors that together affect women's health status.
