OBJECTIVE: Necrotizing pneumonia (NP) is a severe complication of lobar pneumonia caused by various pathogens. The immunopathogenesis and clinical characteristics of NP in children are not clearly understood. We wanted to evaluate the clinical characteristics and suggest in part the immunopathogenesis of NP. METHODS: We reviewed retrospectively the medical charts and radiographic materials of eight patients with NP, who were diagnosed by chest radiography and chest computed tomography at the Department of Pediatrics, Soonchunhyang University Hospitals at Cheonan and Bucheon from January 2002 to December 2011. RESULTS: They were previously healthy, 2.1 to 4.6 years of ages (mean, 2.8+/-1.0 years) and three boys and five girls. All of them had pleural effusion. Five patients had pneumonic consolidations in right upper lung field. Three patients had pneumatocele. They developed leukocytosis (mean, 19,400+/-6,400/mm3), higher C-reactive protein level (mean, 25.1+/-8.0 mg/dL). The etiologic agents were revealed in two patients; Streptococcus pneumonia (S. pneumonia) was revealed in one patient and S. pneumonia and Mycoplasma pneumonia in the other patient. Three patients were treated with additional intravenous immunoglobulin. Clinical improvement was prolonged: fever lasted 10 to 23 days, and length of hospitalization was 15 to 36 days. NP or pneumatocele were completely resolved on the follow-up radiographic studies in all of the patients. CONCLUSION: Although the previously healthy young children with NP had protracted clinical course, they recovered without any problematic sequelae. Our results suggest that the immunopathogenesis of NP in children may be associated with the exaggerated immune reaction of the host to insults from initial bacterial infections, rather than the pathogen-induced cytopathies.

Meigs' syndrome is defined as serous ascites and hydrothorax in association with a benign ovarian fibroma, thecoma, granulosa cell tumor; the ascites and hydrothorax must resolve fully after removal of the tumor. Pseudo-Meigs' syndrome refers to the same clinical features associated with other ovarian or gynaecological tumors. Although struma ovarii is associated with ascites in up to one third of cases it has only rarely been reported to cause Pseudo-Meigs' syndrome. We have experienced a case of Pseudo-Meigs' syndrome with an elevated CA 125 resulting from struma ovarii with a brief review of the concerned literatures.

OBJECTIVE: To investigate the predictive index of functional recovery after primary pontine hemorrhage (PPH) using the combined motor evoked potential (MEP) and somatosensory evoked potential (SEP) in comparison to the hematoma volume and transverse diameter measured with computerized tomography. METHODS: Patients (n=14) with PPH were divided into good- and poor-outcome groups according to the modified Rankin Score (mRS). We evaluated clinical manifestations, radiological characteristics, and the combined MEP and SEP responses. The summed MEP and SEP (EP sum) was compared to the hematoma volume and transverse diameter predictive index of global disability, gait ability, and trunk stability in sitting posture. RESULTS: All measures of functional status and radiological parameters of the good-outcome group were significantly better than those of the poor-outcome group. The EP sum showed the highest value for the mRS and functional ambulatory category, and transverse diameter showed the highest value for "sitting-unsupported" of Berg Balance Scale. CONCLUSION: The combined MEP and SEP is a reliable and useful tool for functional recovery after PPH.
