Periventricular-intraventricular hemorrhage (PV-IVH)is one of the most important neurologic lesion of the low birth weight infants. Serial neurosonographic exeaminations were performed in 113 low birth weight infants who were admitted to the neonatal intensive care unit of Presbyterian Medical Center from November 1, 1990to July 31, 1991. The results were summarized as follows: 1) The incidence of PV-IVH in the study was 54% 2) According to Papile's grading system of PV-IVH, grade I was 32.8%, grade II was 45.9%, grade IIIwas 11.5% and grade IV was 9.8%. 3) The onset of PV-IVH was within the first 7 days of life in 82%. 4) Poor activity, apnea, bradycardia and hypotension were statistically significant clinical findings associated with PV-IVH(P<0.05). 5) The risk factors associated with PV-IVH were gestational age, birth weight, hyaling membrane disease, patent ductus arteriosus and artifical ventilation. 6) The mortality of PV-IVH was 0% for grade I, 10.7% for grade II,42.9% for grade III and 83.3% for gradeIV.

Inflammatory myopathies are comprised of three major subsets, polymyositis, dermatomyositis and inclusion body myositis. Although their etiology is unclear, each group retains its characteristic clinical, immunopathologic features. In polymyositis, a CD8+ T-cell mediated cytotoxicity against muscle fibers has emerged as the main pathologic event, whereas in dermatomyositis complement-mediated injury by antibody may be the primary pathology. There has been several reports on polymyositis internationally but we could find only a few reports in Korea. We report here a 8-year old female patient admitted with a stuporous mentality. After coughing and fever for 3 days, she got myalgia, abruptly developed gross hematuria and dyspnea. After admission, she showed weak self respiration and exclussively elevated muscle enzyme in blood chemistry. In muscle biopsy, lymphocytic infiltrations were found in the fascicles without endomysial fibrosis and these lymphocytes were composed of T lymphocytes on immunohistochemical stain. She received two infusions of intravenous immunoglobulin(1g/kg/day), and showed dramatic improvement in symptoms and signs.

Nodular regenerative hyperplasia (NRH) of the liver is an uncommon disease entity, especially in the pediatricage group. A few cases have been reported in the radiologic literature, but follow-up imaging studies are rare. We describe a case of NRH, diagnosed by ultrasound-guided needle biopsy, in a seven-month-old infant with cri-du-chat syndrome. Initial ultrasound revealed several small hypoechogenic nodules in the liver, but CT and MR failed to demonstrate their presence. Two follow-up sonographic examinations were performed 7 and 20 months later, revealing increases in the size and number of the nodules.

Partial or complete loss of innervation of skeletal muscle leads to muscle weakness and atrophic changes, resulting in decreased muscle volume with fatty replacement. Rarely, enlargement of the affected muscle may occur, related to two processes: true hypertrophy and pseudohypertrophy. We report CT and MR findings of the pseudohypertrophy of calf muscles, especially the soleus and gastrocnemius muscles, in a patient with diabetic neuropathy that showed increased muscle volume with diffuse fatty replacement and the presence of scanty muscle fibers.
