In 1987 the worldwide health program, the Safe Motherhood Initiative, was launched in Nairobi by international organizations to combat the alarming rate of maternal mortality resulting from pregnancy and delivery complications that takes 500,000 lives a year, 98% of them in developing countries. Yet the rate has scarcely diminished since ten. In underdeveloped countries maternal mortality is around 400 per 100,000 live births compared to 10-20 in Europe. The rate is the highest in high fertility regions such as Africa and Southeast Asia. The causes are blood loss, infection, hypertensive episodes during pregnancy, rupture of the uterus, and sepsis from botched induced abortion. In postpartum hemorrhage, especially in grand multiparous women, blood transfusion can be lifesaving. However, in a large part of Africa blood is often unusable because of infection with AIDS. In Jamaica and Bangladesh family planning campaigns particularly aimed at adolescents have yielded good results. In Zimbabwe campaigns target mostly men because of their authority. The utility of basic training of traditional birth attendants (TBAs) in delivery is highly questionable, and more thorough going training is being evaluated. Obstacles to reduction of maternal mortality within the Safe Motherhood program include shortage of funds, lack of coordination with local entities, inadequate antenatal care, illiteracy, and cultural barriers. Communication and training activities are essential, as demonstrated by the Matlab project in Bangladesh. The Matlab region had 200,000 people, 83% of women were illiterate, and maternal mortality reached 400 per 100,000 live births. 3 years after schooled midwives trained TBAs and integrated care for pregnant women, and transportation by boat to a newly built clinic was arranged, the maternal mortality rate declined to 140 from 380 per 100,000 live births in the intervention area (p = 0.02) compared to the control region. In the coming year the halving of maternal mortality is envisioned through prevention of anemia, tetanus, and extensive contraceptive use.

The literature contains about 500 cases of equine leucosis, though the reports are deposited in a great number of journals and vary considerably concerning particular topics. During the last years there has been a remarkable increase of publications about this syndrome in the equine. The clinical leucosis key recommended by us has been confirmed in principle considering the latest literature. In about 70 individual symptoms which can be clinically observed in equine with leucosis 11 can be considered as main symptoms because of their frequency; they are again classified in primary (lymph node tumours including splenomegaly--loss of condition, weakness--cachexia, weight loss, periphery oedema), secondary (anorexia, inappetence--fever--paleness of mucous membrane--anaemia--tachycardia) and accessory (incoordination--tachypnoea, dyspnoea--apathy, lethargy) main symptoms. Furthermore in future it will be necessary to take into more consideration the symptoms "recurrent colic" and "hydrothorax" within differential diagnosis. The main symptom "incoordination" (ataxia, asynergy, paresis, paralysis) is used by us more precisely only in case of impairment of nervous system by neoplastic infiltrations and does not signify as possible symptoms of general physical weakness, for example faltering, staggering, tumbling or lameness. The morphological classification follows further on our previous recommendation. There exist generalized forms with tumour infiltrations in abdominal and in thoracic cavity as well as especially in peripheral lymph nodes. On the other hand there are characteristic manifestations in certain regions of the body, which establish distinctly the clinical symptomatology. They are marked as regional multicentric forms with the main localizations "mediastinal", "splenic", "mesenteric" or "intestinal".(ABSTRACT TRUNCATED AT 250 WORDS)

Nineteen cases of canine acute leukemia were diagnosed during a 4-year period. Two main categories were identified on the basis of cytologic, hematologic, and clinical features: acute lymphoid leukemia and acute myelogenous leukemia. Clinical features included history of weight loss, anorexia, shifting limb lameness, and incoordination. Physical findings were characterized by hepatomegaly, splenomegaly, mild generalized lymphadenopathy, and pallor. Ocular lesions were found in 29% of dogs with acute myelogenous leukemia. Hematologic abnormalities included anemia, thrombocytopenia, pancytopenia, leukemia, and leukoerythroblastic reactions. Results of therapy were discouraging.

A 36 year old woman was admitted to the hospital in November 1983 because of her inability to walk. For 3 months prior to admission, she took oral contraceptives (OCs) as a treatment for amenorrhea. 2 months prior to admission, she had general malaise, anorexia, and unsteady gait. 1 month before her admission, tingling and numbness began in the fingertips and spread up to the forearms, a tight feeling around the waist developed, and walking became ataxic. On admission to the hospital, she was thin and pale with greying hair. Her mind was clear and there were no abnormalities of the cranial nerves. Her extremities were hypotonic but not wasted. Slight muscle weakness of the hands and feet was noted. There was myokymia in both legs. Deep tendon reflexes of the extremities were absent. The plantar responses were extensor and lack of coordination in the extremities was noted. There was a definite glove and stocking type of hypesthesia to pinprick and cotton wool. Vibration sense was decreased below T11 and lost in both legs. There was a marked loss of position sense to passive movement in the legs and some impairment in the hands. Laboratory examination revealed mild magaloblastic anemia, elevated LDH, borderline low concentration of vitamin B12 in the serum, increased excretion of methylmalonate in the urine, achylia, positive antiparietal cell antibody and positive anti-intrinsic factor antibody. Cyanocobalamin absorption by the Schilling test was 5.6% after intrinsic factor, 11.3%. The diagnosis of pernicious anemia was made. Upper gastrointestinal studies showed typical carcinoid tumors of the stomach. Cerebrospinal fluid was normal. Peripheral nerve conduction studies demonstrated normal or slightly decreased motor conduction velocities and absent sensory action potential. Sural nerve biopsy was performed. Myelinated fibers were moderately decreased in number to 5554/mm squared and pronounced loss of large myelinated fibers was demonstrated in fiber histogram. Teased method of the single fiber showed mainly axonal degeneration. Anemia and neurologic function improved rapidly with parenteral hydroxocobalamin therapy and 1 month after treatment commenced, she was able to walk without assistance. The clinical significance of peripheral nerve involvement of subacute combined degeneration of the spinal cord was discussed, as the peripheral nerve affection is only poorly understood in contrast to the myelopathy. This was followed by discussion of the possible effect of the OCs and gastric carcinoid to neurological manifestation of pernicious anemia. (author's modified)

Grass hay produced in the Coeur d'Alene River Basin of northern Idaho was fed to a group of 4 ponies. The hay contained Pb in concentration of 423 +/- 82 mg/kg and Cd in concentration of 10.8 +/- 1.4 mg/kg, resulting in daily exposures of the ponies to approximately 7.4 mg of Pb/kg and 0.19 mg of Cd/kg/day. The results in this group of ponies were compared with those from a group fed noncontaminated grass hay and given a daily dose of 10 mg of Pb/kg of body weight, in the form of lead acetate. Clinical toxicologic signs, hematologic changes, and blood and tissue Pb concentrations were similar in the 2 groups. However, the severity of the disease process appeared to be greater in the ponies fed the Pb- and Cd-contaminated hay. This was shown clearly by the shorter interval between onset of clinical changes and death in the ponies fed contaminated hay. The possibility of multiple heavy metal effects is discussed. Clinical toxicologic signs observed include incoordination, labial paresis, pharyngeal paresis, CNS depression, anorexia, and body weight loss. Anemia or marginal anemia was common and was often accompanied by the appearance of nucleated RBC and Howell-Jolly bodies in peripheral blood. Neither the hematologic response nor the blood Pb concentrations were reflective of the severity of poisoning, although blood Pb concentrations were greater than 0.35 micrograms/ml once clinical signs of toxicity were observed. Liver, kidney, spleen, brain, and bone Pb concentrations and liver, kidney, and brain Cd concentrations were increased in both the ponies fed contaminated hay and the ponies given lead acetate.

A total of 22 nonsplenectomized Hereford, Holstein-Friesian, and cross-bred 18-month-old cattle were used to assess the degree of protection conferred by previous infection with Babesia bovis or B bigemina against infection and disease from tick-borne challenge exposure with the heterologous species. Prior infection with B bigemina or B bovis did not significantly (P less than 0.05) reduce the susceptibility of cattle to tick-borne infection and disease caused by the heterologous species. Carrier infections were not activated during heterologous species challenge exposure, nor was the severity of the challenge-exposure infection aggravated. Immunologic cross reactivity in the indirect fluorescent antibody test was restricted to the period during and shortly after recovery. Homologous indirect fluorescent antibody titers persisted long after primary infections with B bovis, but gradually declined in B bigemina-immune cattle. Babesia bovis infections caused severe reactions characterized by high fever, pancytopenia, and death of 9 of 15 infected cattle. Total serum bilirubin and urea nitrogen values increased markedly within 24 hours preceding death and were often accompanied by clinical signs of CNS involvement (incoordination, opisthotonos, and paddling). Microscopic lesions were restricted largely to kidney, CNS, and liver parenchyma and were characterized by vascular congestion and aggregation of infected erythrocytes in small vessels. Babesia bigemina, in contrast, caused only mild fever and anemia despite prolonged parasitemia and marked thrombocytopenia. The absence of significant (P less than 0.05) heterologous species immunity indicated that protection of cattle from these 2 babesial parasites will require specific immunization against each species.

Equine ehrlichiosis is a seasonal disease of horses first reported in 1969. Clinical signs in horses include high fever, depression, partial hypophagia, anorexia, limb edema, petechiation, icterus, ataxia, and reluctance to move. Hematologic changes include leukopenia, thrombocytopenia, icterus, anemia, and inclusion bodies, principally in neutrophils and occasionally in eosinophils. Diagnosis is made by clinical signs and observing characteristic morulae in a blood smear with standard Wright's stain. Mortality is low unless secondary infection develops or injury occurs as a result of incoordination. Treatment with tetracycline produces prompt defervescence of fever and gradual improvement of clinical signs.

Seven related Bernese Mountain Dogs developed a syndrome Characterized by progressive cerebellar and hepatic disease. Clinically, stiffness in the hind limbs, mild incoordination, and a slight head tremor were first noticeable when pups were 4 to 6 weeks old. The condition progressed, causing pups to assume a wide-based stance. Other signs included head bobbing, spontaneous nystagmus, and, finally, paresis. Hematologic findings included leukocytosis with a left shift; normocytic, normochromic anemia; hypoproteinemia, low serum creatinine, and urea nitrogen concentrations; excessive fasting plasma ammonia concentration; and an increase in concentration of serum bile acids. Portal venography performed on 1 dog revealed a small liver and extensive extrahepatic varicosities. Necropsy revealed cerebellar hypoplasia, nodular liver, extensive abdominal varicosities, and ascites. Histologically, degeneration and depletion of Purkinje's cells and vacuolation, degeneration, and nodular regeneration of hepatic tissues were evident. Preliminary analysis of the pedigree was suggestive of an autosomal recessive pattern of inheritance.

The acute toxicity of dried Nerium oleander leaves to Najdi sheep is described in 12 sheep assigned as untreated controls, N. oleander-treated once at 1 and 0.25 g/kg body weight and N. oleander-treated daily at 0.06 g/kg body weight by drench. Single oral doses of 1 or 0.25 g of dried N. oleander leaves/kg body weight caused restlessness, chewing movements of the jaws, dyspnea, ruminal bloat, incoordination of movements, limb paresis, recumbency and death 4-24 hr after dosing. Lesions were widespread congestion or hemorrhage, pulmonary cyanosis and emphysema, hepatorenal fatty change and catarrhal abomasitis and enteritis. The daily oral doses of 0.06 g dried N. oleander leaves/kg body weight caused less severe signs and death occurred between days 3 and 14. In these animals, the main lesions were hepatonephropathy and gelatinization of the renal pelvis and mesentry and were accompanied by significant increases in serum AST and LDH activities, in bilirubin, cholesterol and urea concentrations and significant decreases in total protein and albumin levels, anemia and leucopenia.

A five-year-old female dog was presented with a four-week history of inappetence, weight loss, and skin and gait abnormalities. Physical examination revealed weakness, depression, incoordination of the posterior limbs, emaciation, skin and hair coat alterations, peripheral lymphadenopathy, pale mucous membranes and fever. Laboratory analysis of samples revealed abnormalities which included anaemia, neutrophilic leucocytosis, thrombocytopenia, low serum glucose and albumin concentrations, and increased serum alkaline phosphatase activity. The diagnosis was confirmed microscopically, by demonstrating the presence of Hepatozoon canis gametocytes within neutrophils in Giemsa-stained peripheral blood smears. Treatment consisting of toltrazuril and a trimethoprim-sulfamethoxazole combination was effective in relieving the clinical signs and clearing the blood of H. canis gametocytes. To the authors' knowledge, this is the first detailed clinical description of H. canis infection in a dog in Turkey.
