Cases of otitis media in infants under 12 weeks of age were reviewed to delineate the frequency, clinical features, and etiologic agents involved. Tympanocentesis was performed in 42 infants, 0 to 5 weeks of age, and in 17, from 6 to 11 weeks of age. The most common symptoms were irritability/lethargy (69%), fever (52%), cough (36%), vomiting (21%), diarrhea (20%), tachypnea (20%), and anorexia (18%). Associated illnesses were present in 33 (54%) of the patients, the most common being pneumonia (9), bronchiolitis (7), meningitis (6), conjunctivitis (4), and omphalitis (4). No peripartum infections or severe perinatal problems were found. Common respiratory pathogens were the predominant etiologic organisms, but coliform organisms were identified in 18% of the infants under 6 weeks of age. Cultures were sterile or grew organisms of questionable pathogenicity ("nonpathogens") in 39% of specimens. Since the signs and symptoms of otitis media in children less than 12 weeks of age are nonspecific and frequently associated with other major illnesses, the physician caring for these infants needs to be more aware of this disease and the therapeutic problems it presents.

Five nondiabetic, chronically alcoholic patients presented in a comatose state during a two month prospective study and were found to be ketoacidotic. All of the patients were men, 28 to 59 years old. The usual history was one of chronic heavy, daily alcohol consumption until one to three days before presentation, when persistent anorexia, abdominal distress, nausea and vomiting commenced, with abstention from food thereafter. The patients were found to be in hypoglycemic coma, with diaphoresis, tachypnea and tachycardia, and immediately awoke when intravenous infusion of glucose was started. Serum glucose ranged between 19 and 27 mg per dl, the average arterial pH was 7.19 and the mean anion gap was 25 mEq per liter. Reaction with Acetest tablets was positive for ketones in both serum and urine in three of the patients. Serum beta-hydroxybutyrate was elevated in the four patients in whom it was measured. Lactic acidosis was not present. All patients were managed with prolonged intravenous infusions of glucose and saline solutions, and within 12 to 18 hours they were feeling well and findings on serum chemistry studies were normal. Follow-up after three months showed no repeated difficulties. The combination of alcoholic ketoacidosis and hypoglycemic coma in nondiabetic persons has not been described in the literature as a clinical entity; it may, however, represent a common but unrecognized syndrome. Therefore, because of its potentially serious consequences and because treatment is simple and effective, this entity must be thought of in alcoholic patients with altered mental status.

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)

In a survey of fungi and mycotoxin conterminating acha (Digitaria exilis Stapf) in Plateau State of Nigeria, 96 fungal isolates were made. Screening of the fungi isolates for their mycotoxin-producing potentials showed that Aspergillus quadrilineatus (Thom and Raper) produced some of the most toxic mycotoxins. Two extracts of the Aspergillus quadrilineatus (the petroleum ether soluble extracts [PER] and the petroleum ether defatted crude extract [PEDCR]) were tested for acute toxicity in mice, chicks and cattle. The ip LD50 of PER in mice was 1148 mg/kg, and the oral LD50 of PEDCR was 566 mg/kg in mice and 556 mg/kg in chicks. The ip LD50 of PEDCR in mice was 21 mg/kg. The toxic signs of PER and PEDCR in mice and chicks included tachypnea, tachycardia, anorexia, somnolence, diarrhea, coma and death. The main postmortem findings were congestion of heart, liver, kidney and lungs and sloughing of the wall of stomach and hemorrhagic enteritis. The histopathologic findings in dead animals included edema and mild degeneration of the myocardium and necrosis of kidney tubular epithelial cells, hepatocytes and bronchioles. The only clinical observation in 1 calf orally dosed with a culture of Aspergillus quadrilineatus of maize was transient whole body tremors which occurred 1 h after dosing, tachycardia and profuse salivation. No significant histopathologic changes were found in the organs of the sacrificed calf.

Tumor necrosis factor (TNF) is a peptide secreted by macrophages in response to endotoxin that can produce many of the changes seen in septic shock. After cecal ligation and puncture (CLP) rats gradually develop tachycardia, hypotension, tachypnea, and hypothermia. At 5 h post-CLP, rats have a peak in serum levels of endotoxin and 60% of rats have blood cultures that grow Gram-negative rods (Escherichia coli and Klebsiella pneumonia). At 20 h post-CLP all rats develop positive blood cultures. Serum levels of TNF are not reproducibly measurable in rats following CLP. Rats undergoing CLP have a 50-80% mortality with deaths usually occurring 24-72 h postinjury. Repetitive (twice daily x 6 d) i.p. injection of sublethal doses of recombinant human TNF-alpha (100 micrograms/kg) to rats undergoing CLP 1 d after the treatment period resulted in a significant reduction in mortality compared to control rats previously unexposed to rTNF (P less than 0.03). Animals treated with rTNF had no hypotension or hypothermia after CLP and regained normal food intake faster than control rats. 12 h after CLP the gene expression for manganous superoxide dismutase (MnSOD), an inducible mitochondrial metalloenzyme responsible for cellular resistance to injury from toxic reactive oxygen species, was higher in livers of rats treated with rTNF suggesting that the TNF treatment augmented expression of this protective enzyme. Unlike MnSOD, expression of the gene for copper-zinc SOD was not affected by CLP or rTNF treatment. The results suggest that prior treatment with recombinant TNF can ameliorate the lethality, hypotension, hypothermia, and anorexia of Gram-negative sepsis in rats and that the mechanism may be related to enhanced hepatic expression of the gene for MnSOD. Repeated administration of recombinant TNF may be a strategy to minimize mortality and morbidity of Gram-negative sepsis.

During the early 1970s, attention was called to the changing demographics and poor prognosis of patients with miliary tuberculosis. Thirty-eight non-AIDS patients with miliary tuberculosis seen since 1975 are reviewed. Their average age was 60 years. Two-thirds of the patients had comorbid conditions. Presenting symptoms were nonspecific; fever, anorexia, sweats, and weight loss were the most frequent. Fever, tachypnea, rales, and altered mental status were the most commonly associated signs. Chest radiographs often showed miliary disease, but the remainder of the laboratory abnormalities were nonspecific. Seventy-six percent of sputum cultures, 75% of gastric aspirate cultures, 59% of urine cultures, and 54% of bronchial washings were positive for Mycobacterium tuberculosis. Biopsy specimens, including those obtained by transbronchial biopsy, were frequently abnormal histologically but were rarely culture-positive. Mortality attributable to miliary tuberculosis was 21%. Risk factors for death included female sex and altered mental status. No patient treated initially with a regimen that included streptomycin died whereas 21% of those treated with other regimens died. These data confirm and extend the results of earlier studies and suggest that miliary tuberculosis is a disease of the elderly and immunocompromised and is associated with significant morbidity and mortality. A high index of suspicion and diagnostic persistence are required for diagnosis.

The antibiotic era has changed the incidence, causal factors, and gravity of empyema. Between 1977 and 1988, 27 children with empyema were surgically managed. Ten cases occurred after an operation (8 esophageal and 2 abdominal). There were 15 girls and 12 boys. The age range was newborn to 12 years. Symptoms included fever, cough, tube drainage postoperatively, anorexia, weight loss, chest pain, tachypnea, and lymphadenitis. Multiple aerobic and anaerobic organisms were cultured. Treatment included thoracentesis and antibiotics, tube thoracostomy, tube thoracostomy and bronchoscopy, decortication, or decortication with lobectomy. The total hospital stay averaged 28.3 days, and after decortication, 11.6 days. Empyemas in children frequently have multiple organisms and should be treated with broad-spectrum antibiotics while awaiting culture results. Thoracentesis and tube thoracostomy are often ineffective in curing the disease. Decortication can abbreviate hospital stay if performed promptly for persistent pleural sepsis.

3-methylindole (3-MI) dissolved in the lipophilic carrier Cremophore EL was administered intraperitoneally to male, twelve-week-old Sprague-Dawley rats. Gross and histopathologic changes in the lungs were studied using light microscopy at three time-periods following administration: 16, 24, and 46 hours. Both 3-MI and Cremophore caused changes in bronchiolar epithelium at 16 hours. By 46 hours, Cremophore-injected rats showed no effects of the carrier; whereas, 3-MI rats showed severe lung changes characterized by airway epithelial and pulmonary vascular endothelial necrosis and sloughing, cellular infiltration by lymphocytes and macrophages, perivascular edema, alveolar edema, and lymph stasis. Grossly, the controls showed no effect of the carrier and none died during the studies. In contrast, 3-MI injected rats quickly became lethargic and displayed tachypnea, anorexia, and progressive respiratory distress. Two of five 3-MI rats in the final group died just prior to 46 hours. All of this group had grossly congested lungs and marked pleural effusion. The lesions and time course showed similarities to those observed in ruminants and mice. We conclude that 3-MI in Cremophore causes an acute progressive pneumonitis in rats and suggest that the rats may be a suitable model for 3-MI-induced and similar toxic lung diseases in domestic animals and people.

Four litters of puppies were divided into three groups. One group was vaccinated with a live CAV-1 vaccine and another with a live CAV-2 vaccine. Throat swabs were collected from two dogs in each of these groups to monitor the possible excretion of vaccine virus, but none was found. Both groups, together with the third group of unvaccinated controls, were challenged 17 days later with an aerosol of virulent CAV-2. One dog from each group was killed on the third, fourth, seventh, ninth, 11th and 14th days after challenge. The unvaccinated dogs developed a clinical disease characterised by anorexia, dullness, coughing and tachypnoea. The lungs were consolidated and histological examination revealed the main lesion to be a severe necrotising bronchiolitis. Large amounts of virus were present in the respiratory tissues of these dogs and high titres of virus were isolated from throat swabs. In contrast, both groups of vaccinated dogs remained clinically almost normal with minimal lesions, present for a much shorter period of time. Virus was found on day 4 in the respiratory tissues of one dog vaccinated with CAV-1 but the other vaccinated animals contained little or no virus. In general, the degree of protection afforded by CAV-1 vaccine seemed similar to that provided by CAV-2 vaccine.

A six-week-old female borzoi puppy from a brother-sister mating developed a generalised illness characterised by anorexia, temporary intention tremor, episodic pyrexia, tachypnoea, conjunctivitis, otitis and neck pain. Haematological abnormalities included an inflammatory leukogram and regenerative anaemia. Blood cultures remained sterile; clinical chemistry values were unremarkable. The puppy had recurrent seizures and was euthanased when 18 weeks old. Post mortem examination revealed a multisystemic inflammatory disease involving thyroids, lymph nodes, spleen, pancreas, bladder and lung, but no lesions to account for the neurological signs. The cause of this generalised disease was not recognised. The histological features are unusual and resemble those described in other dogs of this breed.
