PURPOSE: The incidence of bronchopulmonary dysplasia(BPD) may further increase in the coming decade as advances in neonatal intensive care enable clinicians to save even smaller, younger and more critically ill infants. The purpose of this study was to evaluate risk factors and prognosis associated with BPD in premature infants. METHODS: The retrospective review on RDS infants admitted to the neonatal intensive care units at the Chonnam University Hospital was done from Jan. 1995 to July. 1997. These infants were divided into two groups, BPD group(n=25) and non-BPD group(n= 112). The incidence, risk factors and therapeutic results of BPD were analyzed. RESULTS: Infants in the BPD group had lower birth weight, gestational age, and lower 1 min Apgar score compared to that of infants in the control group. The incidence of BPD was 18.2Yo and was higher in male infants. Longer duration of oxygen, ventilatory support and higher PIP were noted in the BPD group. There were no significant differences between the two groups concerning duration of postnatal requirement of oxygen supplementation, ventilatory support, and ventilatory parameters such as FiO2 and PEEP. The incidences of PDA and pneumothorax mean fluid volume and weight loss were similar in two groups. Frequent episodes of respiratory infection occurred(31.6%) in BPD group and one patient expired during 6 to 12 month follow up. 22 infants(88%) received dexamethasone in BPD group. Side effects of dexamethasone including hypertension and hyperglycemia occurred in 59.1% and 31.8%, respectively. CONCLUSION: The overall incidence of BPD was 18.2% and the risk factors for BPD included lower birth weight and gestational age, lower Apgar score at 1 minute, longer duration of oxygen and ventilatory support with higher PIP.

PURPOSE: Peramivir is the first intravenously administered neuramidase inhibitor for immediate delivery of an effective single-dose treatment in patients with influenza. However, limited data are available on intravenous (IV) peramivir treatment compared to oral oseltamivir for these patients. MATERIALS AND METHODS: With a systematic review and meta-analysis, we compared the efficacy of IV peramivir with oral oseltamivir for treatment of patients with seasonal influenza. MEDLINE, EMBASE, and Cochrane Central Register were searched for relevant clinical trials. RESULTS: A total of seven trials [two randomized controlled trials (RCTs) and five non-randomized observational trials] involving 1676 patients were finally analyzed. The total number of peramivir- and oseltamivir-treated patients was 956 and 720, respectively. Overall, the time to alleviation of fever was lower in the peramivir-treated group compared with the oseltamivir-treated group [mean difference (MD), −7.17 hours; 95% confidence interval (CI) −11.00 to −3.34]. Especially, pooled analysis of observational studies (n=4) and studies of outpatients (n=4) demonstrated the superiority of the peramivir-treated group (MD, -7.83 hours; 95% CI −11.81 to −3.84 and MD, −7.71 hours; 95% CI −11.61 to −3.80, respectively). Mortality, length of hospital stay, change in virus titer 48 hours after admission, and the incidence of adverse events in these patients were not significantly different between the two groups. CONCLUSION: IV peramivir therapy might reduce the time to alleviation of fever in comparison with oral oseltamivir therapy in patients with influenza; however, we could not draw clear conclusions from a meta-analysis because of the few RCTs available and methodological limitations.

A previously healthy 44-year-old woman who was diagnosed as having dermatomyositis suddenly developed severe dyspnea while being in the state of improved condition of muscle weakness. Interstitial lung disease was found on high resolution computed tomography (HRCT). In spite of the treatment with the immune-modulating agent (high dose steroid, cyclophosphamide, immunoglubulin and cyclosporine), her condition deteriorated further and rapidly, leading to death. More intensive agent such as FK506 would be necessary in those cases of dermatomyositis-related interstitial lung disease that have poor prognostic factors.

The objective of this study was to determine how the neonatal mortality rate has changed since surfactant (S) therapy was introduced in our Neonatal Intensive Care Unit (NICU), and to evaluate the efficacy of surfactant therapy in respiratory distress syndrome (RDS) patients. Incidences of risk babies such as outborns, prematurity, low birth weight infants and RDS, and neonatal mortality rates were compared between 'pre' (control, 1988 to 1991, n=4,861) and 'post' S period (study, 1993 to 1996, n=5,430). In RDS patients of 'post' S period, neonatal mortality rate was compared between S-treated and non-treated patients, and chest X-ray and ventilatory parameters were compared between pre- and post-72 hr of surfactant treatment. Surfactant therapy showed short term effects, judging by the decrease of early neonatal deaths and improvement of chest X-ray and ventilatory parameters in RDS patients. The overall neonatal mortality rate had a tendency to decrease in spite of increased incidences of risk babies in 'post' S period but it was less than expected. The reasons were thought to be that we had a high proportion of risk babies, and there was some bias in patient selection for surfactant therapy and its use. In conclusion, with the active prevention of risk baby delivery and appropriate use of surfactant, better results could be expected.

Schwannoma arising from cervical sympathetic chain is relatively uncommon and can be occasionally misdiagnosed as carotid body tumor. On MR images, schwannoma shows generally hypointense features on the T1-weighted images and hyperintense features on the T2-weighted images. Occasionally, however, contrast administration, which lets schwannoma show marked enhancement, may make it difficult to differentiate schwannoma from carotid body tumor. A 41-year-old woman presented a neck mass on the left. MR images of the neck and carotid angiography revealed a well-enhancing ovoid tumor, which separated the internal carptod arteries from the external carotid arteries at the level of carotid bifurcation. Complete tumor resection was performed and histopathology findings confirmed a schwannoma originating from the sympathetic chain. Postoperatively, miosis and facial anhydrosis of the left side were noted without ptosis, enophthalmos or other neurologic deficits. We report this case with a review of the literatures.

Pneumatosis cystoides intestinalis is an uncommon condition of unknown etiology, characterized by the presence of multiple gas filled cysts in the gastrointestinal tract. Many different causes of pneumatosis cystoides intestinalis have been proposed, including mechanical, pulmonary, and bacterial causes. Approximately 85% of cases are thought to be secondary to coexisting disorders of the gastrointestinal tract or the respiratory system. The condition has been associated with the therapeutic uses of lactulose, steroids, and various cancer chemotherapeutic regimens. Lactitol is a disaccharide analogue of lactulose which is available as a pure crystalline powder. There are three previous case reports suggestive of lactulose causing pnumatosis intestinalis. We report a case of recurrent pneumatosis cystoides intestinalis associated with benign recurrent pneumoperitoneum developed probably secondary to lactitol therapy.

Allopurinol-induced hypersensitivity syndrome is characterized by an idiosyncratic reaction involving multiple-organs, which usually begins 2 to 6 weeks after starting allopurinol. In rare cases, the adverse reactions to allopurinol are accompanied by a variety of liver injury, such as reactive hepatitis, granulomatous hepatitis, vanishing bile duct syndrome, or fulminant hepatic failure. Here we report a case with granulomatous hepatitis and ductopenia. A 69-year-old man with chronic renal failure, hyperuricemia, and previously normal liver function presented with jaundice, skin rash, and fever 2 weeks after taking allopurinol (200 mg/day). In histopathology, a liver biopsy specimen showed mild spotty necrosis of hepatocytes, marked cholestasis in parenchyma, and some granulomas in the portal area. There were vacuolar degeneration in the interlobular bile ducts and ductopenia in the portal tracts. Pathologic criteria strongly suggested the presence of allopurinol-induced granulomatous hepatitis with ductopenia and cholestasis. The patient fully recovered following the early administration of systemic corticosteroid therapy.

It is very rare for an exocervical adenocarcinoma to metastasize to the lung parenchyma and pleura. A 54-year-old woman was admitted with dyspnea and left pleural effusion on chest X-ray. She had a history of exocervical adenocarcinoma 3 years previously and was treated with hysterectomy, chemotherapy, and radiation therapy. Last year, she was diagnosed with a left vestibular schwannoma and underwent subtotal mass removal surgery. After admission, metastatic adenocarcinoma of the pleura was diagnosed by video-assisted thoracic surgery biopsy. We herein report the rare case of exocervical adenocarcinoma that presented as a metastatic lesion to the pleura 3 years after the initial diagnosis.

Coronary artery dissection after blunt chest trauma is very rare conditon, and this can result in a serious acute myocardial infarction. We report a case of a 54-year old male who was presented with an anterior myocardial infarction after traffic accident, with steering wheel injury. His coronary angiography revealed a discrete eccentric 85% stenosis of proximal left anterior descending coronary artery with dissection and intravascular ultrasound showed a dissecting flap from the distal left main coronary artery to proximal left anterior descending coronary artery. He was successfully treated by percutaneous transluminal coronary angioplasty with stent.
