Thirteen cases of group D streptococcal neonatal sepsis and/or meningitis were identified at the Cincinnati Children's Hospital from 1970 to 1976. Ages at onset of disease ranged from 1 to 25 days. The most frequent symptoms were fever (five cases), lethargy (five cases), and respiratory difficulty (four cases). Blood cultures for seven infants were positive; CSF cultures for five infants were positive; and CSF and blood cultures for one infant were both positive. In 12 patients, parenteral antibiotic therapy consisted of a penicillin and an aminoglycoside. One infant with a severe meningomyelocele died. The other 12 infants showed a rapid clinical response with seven patients improving within 48 hours of the start of therapy. Infection with group D streptococcus results in a low-grade systemic disease in both full-term and premature infants that responds favorably to appropriate therapy.

Sarcoidosis is a multisystem disease of unknown etiology characterized by non-caseating granulomatous inflammation of various organs, but most frequently involving the lungs of young adults. Sarcoidosis is rare in the pediatric age group, however numerous extensive reviews have been published. The most commonly seen initial manifestations in childhood are non-specific constitutional symptoms such as lethargy, fatigue and malaise, followed by cough, dyspnea, fever, weight loss, and lymphadenopathy in order of decreasing frequency. The diagnosis is one of exclusion and is established when clinical and radiological findings are supported by histological evidence of widespread non-caseating epithelial cell granulomas in more than one organ, or a positive Kveim test. Laryngeal involvement is usually part of the systemic disease, but isolated laryngeal sarcoidosis has been reported in adults. We report here a case of isolated laryngeal sarcoidosis in a 13 year old girl. The differential diagnosis and management are discussed.

Most attempts at developing a model of autoimmune inner ear disease have focused on the immunization of healthy animals with cochlear tissue. We have chosen an alternate route of studying this entity utilizing the MRL-lpr/lpr (Lupus) mouse, an animal known to spontaneously develop multisystemic, organ nonspecific autoimmune disease. We report on the auditory pathology found in animals at early stages of this systemic disease. At the onset of clinical signs of illness (cachexia, weight loss, lethargy) animals were sacrificed and their cochleas and kidney prepared for morphologic analysis. Significant pathology was seen in the MRL/lpr animals involving the basal and middle turns of the cochlea which could not be correlated with the presence or degree of glomerulonephritis. Findings included outer and inner haircell degeneration, strial edema and degeneration, and an acellular infiltrate in the tunnel of Corti. Cochlear pathology was not found in control animals. Thus, at early stages of systemic disease, MRL/lpr mice manifest significant cochlear pathology not seen in control animals. The implications of these results with regard to the pathogenesis of these lesions as well as their clinical relevance are discussed.

A 20-month-old boy had an 8-week history of vomiting, lethargy, generalized muscle weakness, and seizures. There was no history or clinical signs of an underlying systemic disease or an immunodeficiency. Cerebrospinal fluid (CSF) had 99 nucleated cells/cu mm, malignant cells, high protein and normal glucose. CT and MRI scans showed diffuse meningeal enhancement around the brain and spinal cord, but no parenchymal involvement. Biopsy of the leptomeninges showed malignant cells with marked nuclear pleomorphism and prominent clear to eosinophilic cytoplasm. The immunohistochemical studies were positive for histiocyte-macrophage markers and were negative with T and B cells, Ki-1, neural and glial cell antibodies. Multiple tests revealed no other site of disease. The patient died 3 months after onset of treatment despite intensive i.v. and intrathecal chemotherapy. We have not found any other reported case of primary histiocytic leptomeningeal lymphoma in a young child.

We describe a four-week-old male infant with bilateral renal parenchymal malakoplakia who presented with low grade fever, convulsions and lethargy. The patient had profound anemia, hepatosplenomegaly and bilateral nephromegaly with reduced renal function. Both blood and urine cultures grew Escherichia coli, and antibiotic therapy was started. A kidney biopsy obtained on the 20th hospital day confirmed the diagnosis of renal parenchymal malakoplakia. Following treatment with an intravenous methylprednisolone pulse therapy, the infant made significant clinical improvement. He has grown and developed normally in the three years following this episode. We suggest that the steroid therapy was useful in ameliorating renal parenchymal malakoplakia in a patient without an underlying systemic disease. This report describes the youngest patient to have malakoplakia.

In addition to the commonly reported ocular signs, Chlamydia psittaci infection of kittens resulted in fever, lethargy, lameness and reduction in weight gain following ocular instillation of virulent organisms. The appearance of these systemic signs was late with respect to the appearance of ocular symptoms and occurred simultaneously with increasing levels of chlamydia-specific IgG. Measurement of acute phase reactants and IL-6 in plasma indicated that both became elevated concurrent with or slightly after the appearance of fever and remained elevated after the fever began to resolve. Preliminary data also indicated that infectious C. psittaci was present in the blood stream during this time period. The results of ocular instillation of three different levels of C. psittaci (10(3.8), 10(2.8) and 10(1.5) TCID50) indicated that the frequency of infection and the severity of ocular signs were diminished in the group receiving the lowest dose. However, the magnitude of systemic disease was similar in all animals which exhibited clinical signs, irrespective of the dose administered. The immune response to infection included elementary body (EB)-specific lymphocyte proliferation as well as the development of EB-specific IgG and IgM antibodies. The predominant antibody response was to a 45 kDa protein, the major outer membrane protein (MOMP), lipopolysaccharide (LPS), a 58 kDa doublet and 32 and 16-19 kDa proteins.

Clinical and macroscopic findings (anorexia, lethargy, loss of orientation and exophthalmia) indicate that Streptococcus iniae and Lactococcus garvieae infections of trout share some common features, but histopathology reveals notable differences between the 2 diseases. Meningitis and panophthalmitis are the main lesions among S. iniae infected trout, whereas L. garvieae infection results in a hyperacute systemic disease. Differences in the LD50s of the 2 pathogens and the sudden onset of signs and death correlate with the histopathological findings, indicating the severity of L. garvieae infection of trout.

Two dogs were referred for investigation of lethargy and anaemia. Preliminary examinations by the referring veterinary surgeons had revealed severe anaemia, which was poorly regenerative. In one case, the anaemia was microcytic and, in the other, it was hypochromic. These findings were suggestive of chronic blood loss anaemia. Neither dog had external signs of gastrointestinal disease, although one had vomited on a single occasion during the two weeks preceding referral. Although both dogs were producing grossly normal faeces, further investigations detected faecal occult blood. Multiple full thickness gastrointestinal biopsies were taken at laparotomy. These showed segmental eosinophilic enteritis of the duodenum and proximal jejunum in one case, and marked chronic lymphocytic gastritis in the other. Both cases illustrate the fact that severe systemic disease can result from gastrointestinal pathology in the absence of clinical signs of gastrointestinal disease.

Clinical and pathological findings (anorexia, hemorrhage, lethargy, loss of orientation and exophthalmia) indicated that Streptococcus iniae type II is responsible for a fatal disease in rainbow trout. Histopathological findings revealed that S. iniae type II produces a systemic disease, including a diffuse necrotizing myositis. The distribution of viable bacteria in infected tissues substantiated the pathological findings, confirming that S. iniae type II is responsible for a generalized septic disease of rainbow trout.

Five days after birth of a viable Fell pony filly, yellow watery diarrhoea appeared without any signs of systemic disease. Four days later the diarrhoea ceased. On 11th day, the animal showed apathy, and a few days later, the foal was very lethargic, suffered from muscular weakness and severe watery diarrhoea that reappeared. The illness did not respond to therapy. At the age of 21 days the filly spontaneously died under symptoms of intestinal colic and pneumonia. Haematological examinations revealed lower numbers of erythrocytes as well as non-selective lymphopenia. Phagocytic activity was slightly increased, lymphocyte activity was inhibited. Histopathology showed severe alteration of the lymphatic organs. T and B lymphocytes and antigen-presenting macrophages were not arranged in characteristic areas, and the quantity of these cells was lower than would be expected. Histopathological changes in lymphatic organs resembled those described in the literature as severe combined immunodeficiency.
