To focus attention on the problem of infant mortality in Lebanon, data were compiled on infant mortality from 1978 to 1986 at the American University of Beirut Medical Center. Causes of death are analyzed for 602 males and 398 females. 54.9% deaths occurred at 1 month of age and 77.4% died within the 1st year. Autopsies were performed on .7%. 37.7% of all neonatal deaths were due to neonatal diseases such as hyaline membrane disease, asphyxia neonatorum, immaturity, necrotizing enterocolitis, hemorrhage, hemolysis, meconium aspiration, and kernicterus. Better prenatal care would reduce this group, or the administration of corticosteroids to the mother 24-48 hours prior to delivery, as well as rapid resuscitation at birth and prevention of the 5 curses: hypoxemia, hypoglycemia, hypothermia, hypotension, and acidosis. Although unavailable in Lebanon, administration of surfactants through an endotracheal tube would also help. Infections constitute 25.1% of deaths; many are preventable through adequate public health measures and strict personal hygiene, i.e., diseases such as sepsis, pneumonia, meningitis, gastroenteritis, hepatitis, encephalitis, and 1-2 cases of the following: diphtheria, measles, peritonitis, tetanus, tuberculosis, cytomegalis inclusion, herpes, parathyphoid, pertussis, poliomyelitis, and shigellosis. Congenital diseases were 21.6%. In utero diagnosis could prevent some diseases and in utero treatment is possible for hydrocephalus and hydronephrosis. Screening programs postnatally could lead to treatment. 5.9% were malignancies such as leukemia, lymphoma, brain tumors, histocytosis, Wilm's tumor, Ewing sarcoma, and Hodgkin's disease. Early diagnosis is critical if mortality is to be reduced in this group, but medical advances are still needed. 2.9% are miscellaneous diseases such as poisoning, rheumatic diseases, marasmus, Reye's syndrome, nephrosis, rickets, and epilepsy. Most of these diseases are preventable, except for rheumatic inflammation of the heart. Recommended necessary steps to reduce infant mortality are: prenatal care, diagnosis and screening, intrauterine surgery; resuscitation and intensive care centers with modern equipment and trained personnel; national vaccination and screening programs; adequate public health measures and hygiene; parental education; and well-equipped hospitals to serve all regardless of income level.

In the period 1973/74-1983 a prospective observation was carried out on 4591 out-patients (2095 males and 2496 females) aged 18-68, with predominantly non-insulin treated diabetes of 1-10 years' duration. During the ten years period over a third of initial cohort died. Age-standardized mortality rate was twice that for the general population of Warsaw for the median year 1978. The risk of death rose with decreasing age, especially in females. The most frequent causes of death were cardiovascular diseases, particularly coronary heart disease, standardized mortality ratios amounting to 2.7 and 2.4 respectively. Among diabetic cohort the risk of death was also higher for nephritis, nephrosis, cirrhosis of the liver and pneumonia. No excess death rate could be found for tuberculosis, malignant neoplasms, and diabetes itself. Diabetic patients were less frequently exposed to accidental deaths than the general population of Warsaw. The mortality diabetic patients in Warsaw was similar to that seen in most of the developed countries with the exception of the higher mortality due to cirrhosis of the liver and smaller due to accident, trauma and poisoning.

From 1980 to 1988 235 koalas were necropsied and 67 were found to have urinary tract disease. Six affected koalas out of 48 were derived from wildlife parks around Sydney while 61 of 187 were derived from free living populations on the central and north coasts of New South Wales. Sixteen had cystitis alone, 5 had cystitis and associated renal disease only, 16 females had cystitis with genital disease, 23 had urinary disease in combination with other systemic disease and 7 had renal disease only. Overall 49 animals had cystitis (30 females and 19 males; 47 being free living) with 12 of these having renal extension (all free living). Cystitis tended to be active but chronic while associated renal disease was mainly designated as hydronephrosis and pyelonephritis. Other forms of renal disease included lymphosarcoma, oxalate nephrosis, acute and chronic nephritis, and microabscessation related to septicaemia. Female genital disease associated with cystitis was commonly vaginitis and metritis. Paraovarian cysts were detected with and without metritis. Other diseases occurring with urinary tract disease included conjunctivitis, dermatitis/stomatitis, pneumonia and hepatic disease. The higher prevalence of urinary tract disease in free living koalas, especially cystitis, is in contrast to captive koalas and may reflect the interaction between disease cause and habitat.

Renal allografts were transplanted into 20 dogs (12 beagles, eight mongrels) following a prescribed protocol for pre-transplantation blood transfusions and kidney exchange. Immunosuppressive therapy (azathioprine and prednisone) was modified as needed for each dog. Seven of the beagle dogs survived for 1 year and were then euthanized; all other dogs died or were euthanized prior to 1 year post-transplantation. Graft rejection and renal failure were the greatest causes of mortality. Renal lesions which contributed to the death of some animals included renal vein thrombosis, nephrosis, and pyelonephritis. Inflammation of the lower respiratory tract (bronchitis, pneumonia, and pleuritis) was a contributory cause of death in some dogs. Cystitis and ureteritis occurred in almost half of the dogs. Prostatitis was seen in six of the 16 male dogs. Adrenal cortical atrophy, parathyroid gland hyperplasia, and bone marrow hypocellularity were seen in a majority of the dogs which survived 1 year.

Pathologic changes and serum electrophoretic patterns were determined in 30 male goats given aflatoxin B1 (AFB1) orally at 4 dosage levels (mg/kg of body weight/day): 0.1 for 34 days; 0.2 for 18 days; 0.4 for 10 days; or 0.0 for 29 days. Goats given AFB1 had increased mean concentrations of gamma-globulins and most had decreased mean concentrations of beta-globulins, although these changes in serum proteins were not significant (P greater than 0.05). At necropsy, ascites, pale livers, petechial hemorrhages, nasal discharge, and icterus were present. Microscopic changes included bile ductule proliferation, hepatocytic karyomegaly, hepatocellular degeneration, pneumonia, rhinitis, and proximal renal tubular nephrosis. Goats given the 2 smaller dosage levels of AFB1 lived longer and had more severe lesions. Goats may be a good model for the study of ruminant aflatoxicosis.

A follow-up study was done on the mortality from 1956 to 1975 among 2,383 Japanese patients with leprosy who were admitted to a leprosarium in Japan. The leprosy was classified into two types: lepromatous and tuberculoid. Irrespective of the type of leprosy or the sex of leprosy patient, mortalities were increased from tuberculosis, pneumonia and bronchitis, nephritis and nephrosis, and from total causes. The suicide rate was high among female patients. Deaths from total malignant neoplasms were higher than expected among patients with lepromatous leprosy for both sexes (49 observed vs. 44.02 expected), whereas they were lower than expected among patients with tuberculoid leprosy (35 observed vs. 36.83 expected); however, the differences were not statistically significant. Mortalities from cancers of the cervix and the esophagus among females with lepromatous leprosy were significantly higher. The risk of lymphoreticular cancers was not increased.

We reviewed the records of 96 children hospitalized with varicella from July 1, 1975 to June 30, 1980. Eighty-one were immunologically normal and 15 were immunocompromised on the basis of neoplasia, immunosuppressive therapy, or genetic disease. These children experienced 106 complications including viral dissemination-encephalitis (44), bacterial infection (25), Reye's syndrome (17), unusual cutaneous lesions (eight), drug overdose (five), diabetic ketoacidosis (two), neonatal infection (two), dehydration (two), and exacerbation of preexisting nephrosis (one). The length of hospitalization varied from one to 38 days with a median of five days. There were ten varicella pneumonia (one), of neonatal varicella (one), and of a ruptured mycotic aneurysm secondary to septicemia (one). This review demonstrates (1) a substantial occurrence of life-threatening complications of varicella in childhood, and (2) a need for prospective epidemiologic data on the incidence of complications to determine the scope and extent of varicella vaccination.

Forty-nine 5-week-old chickens were inoculated by the intravenous (i.v.), intratracheal (IT), or intranasal (IN) routes with either a chicken-origin or one of two duck-origin type A influenza virus isolates. Twelve control chickens were inoculated with sterile chorioallantoic fluid. For all viruses, i.v. inoculation produced predominate lesions of renal tubule necrosis (nephrosis) and nephritis, and influenza virus nucleoprotein was localized in nuclei and cytoplasm of necrotic renal tubule epithelium. Chickens inoculated by the IT route, and to a lesser extent the IN route, had mild to severe tracheitis, bronchitis, and ventromedial pneumonia associated with secondary bronchi but lacked renal tubule necrosis and nephritis. These data indicate low-virulence avian-origin influenza viruses were nephrotropic during simulated systemic infection (i.v. inoculation) and pneumotropic during simulated local infection (IT and IN inoculation). Gross and histologic kidney lesions produced by i.v. inoculation of the chicken-origin influenza virus were similar to changes reported in outbreaks of low-virulence influenza virus in laying chickens.

Chronic mercury toxicity was induced in goats by administering mercuric chloride at 100 micrograms/ml in deionized drinking water offered ad libitum for 90 days. Toxic signs of gastrointestinal disturbances and renal dysfunction developed from 43 days onwards without any mortality. The toxicity also induced nephrosis and tubular nephritis; centrilobular necrosis of liver; mild to moderate necrosis in spleen, intestine and lymph node; Zenker's degeneration of cardiac muscles; exudative pneumonia; and pial congestion, oedema and vacuolation in the brain. In addition, hyperaemia, oedema and tissue haemorrhages were evident in most of the organs. The kidneys contained the largest residues of mercury, followed by liver, spleen, intestine, lymph node, skeletal muscles, lungs, heart, brain and the omental fat. The intensity of the cytotoxic changes in the various organs was proportional to the amount of mercury accumulated.

To investigate the feasibility of using information about the health and management of lambs on farms to predict the risk of gross abnormalities at post-mortem meat inspection, 6732 lambs from 30 different farms in Great Britain were followed through to slaughter in 1995/6. The farm-level data were collected during farm visits at the beginning of the study. Routine meat inspection findings for the lambs were obtained from the 10 participating abattoirs. The most common abnormalities found during post-mortem inspection were pneumonia/pleurisy (53% of cohorts), lungworm (40%), abscesses (30%), liver fluke (27%) and nephritis/nephrosis (27%). The farm-level risk factors associated with abnormalities at slaughter varied with the type of lesion. The most significant risk factor was the age of the lambs at slaughter. Lambs slaughtered at an older age were more likely to have an abnormality, especially pneumonia, abscesses and liver fluke. After age, environmental factors appeared to be better predictors of those cohorts that would have lesions at slaughter than health and disease control variables. However, a much larger study would be required to identify a set of farm-level factors that adequately discriminated between lambs with high and low risks of lesion at slaughter. At the end of the study, the farmers were informed of the meat inspection findings for their lambs and a third indicated that they would improve their animal husbandry as a result of the information.
