Kearns Sayre syndrome (KSS) is a multisystem disorder with a confounding variety of clinical manifestations, including ocular myopathy, pigmentary retinopathy, heart block and ataxia. Endocrinopathies are common in KSS, including growth hormone deficiency, hypogonadism, diabetes mellitus and hypoparathyroidism.  A variety of deletions of mitochondrial DNA(More)
Mice receiving a single intraperitoneal injection of Lactobacillus casei cell wall fragments in aqueous suspension develop an asymmetric inflammatory coronary arteritis which histologically mimics the lesions seen in the coronary arteritis of children with Kawasaki's disease. A large variety of mice with genetically determined defects of the immune system(More)
Kawasaki disease is an inflammatory illness of unknown etiology which is often complicated by coronary arteritis. Systematic study of the pathologically similar coronary arteritis induced in mice by a single intraperitoneal injection of Lactobacillus casei cell wall fragments may provide useful clues to the pathogenesis and appropriate treatment of Kawasaki(More)
In a retrospective study we assessed the hepatic changes in children with the acquired immunodeficiency syndrome by reviewing 12 biopsy specimens and 48 autopsy specimens from 54 children. Hepatopathology differed in biopsy and autopsy material. In biopsy specimens, chronic active hepatitis with predominantly T8 lymphocytes by tissue immunochemistry was(More)
Unilateral testicular trauma in the postpubertal male can lead to alterations in semen analysis, but it is not clear what effect this has on fertility. To better understand how surgical treatment of testicular trauma affects both fertility and testicular histology the following study was performed. Eighty postpubertal Lewis rats were divided into eight(More)
The branch of the right pulmonary artery (RPA) to the upper lobe of the right lung (RUL), the truncus anterior of the RPA, and the pars anterior of the left pulmonary artery, which supplies the left upper lung lobe (LUL), were demonstrated by both dissection of postmortem specimens and angiography for 20 infants and children, by angiography only for 57, and(More)
As an alternative to bladder mucosa, free grafts of tubularized peritoneum were used as urethral substitutes in a rabbit model of hypospadias. In group 1, six mature rabbits underwent partial penile urethrectomy followed by interposition of a 2-cm-long peritoneal-lined tube graft. These animals had urethrograms performed at 3 months and were killed at 6 (n(More)
We describe the induction of an asymmetric, focal, inflammatory coronary arteritis by a single intraperitoneal injection of group B Lactobacillus casei cell wall fragments in various inbred mouse strains. This coronary arteritis resembles the arteritis which is responsible for the 1-2% fatality rate among children with mucocutaneous lymph node syndrome.(More)
An 11-month-old girl had massive rectal bleeding. A midabdominal mass was palpated. Ultrasound scan showed a large cystic mass with diffusely echogenic contents; Tc-99M radionuclide scan confirmed a duplication. Exploratory surgery and pathology examination showed a gastric duplication with formation of a fistula into the transverse colon with a colonic(More)
