Congenital absence of nails usually occur as a rare isolated anomaly or combined with other ectodermal defects. This anomaly is regarded as an inherited disorder either dominantly or recessively but quite a few cases were reported as sporadically developed. The patient was a 2-month-old girl who had no nails on both her 2nd, 3rd toes but had rudimentary nails on her left big toe and both 4th toes at birth. We could not find any other congenital deformity, any family history of inherited diseases related to anonychia. Radiological findings revealed no visualization of both 4th distal phalanges, only. We report this case as congenital anonychia of a sporadic type which may have developed independently from an underlying bone abnormality. We also review other reported cases in the literature.

Ground-glass opacity is a frequent but nonspecific finding seen on high-resolution CT scans of lung parenchyma. Histologically, this appearance is observed when thickening of the alveolar wall and septal interstitium is minimal or the alveolar lumen is partially filled with fluid, macrophage, neutrophils, or amorphous material. It has been shown that ground-glass opacity may be caused not only by an active inflammatory process but also by fibrotic processes. When a focal area of ground-glass opacity persists or increases in size, the possibility of neoplasm-bronchioloalveolar carcinoma or adenoma, or lymphoma, for example- should be considered. Diffuse nonsegmental ground-glass opacity in both lung fields was incidentally found on follow up abdominal CT in a stomach cancer patient and signet-ring cell-type metastatic lung cancer was confirmed by transbronchial lung biopsy. We report a case of diffuse ground-glass opacity seen in metastatic lung cancer from adenocarcinoma of the stomach.

Background: Desflurane, a fluorinated methyl-ethyl ether, has some advantageous properties including low blood solubility, stability in soda lime, and resistance to biodegradation. Desflurane in vivo has demonstrated myocardial depressant property. The purpose of this study was to test the direct effects of desflurane on myocardial contractile function and coronary flow in the isolated heart. Methods: Twelve isolated rat hearts were continuously perfused with modified Krebs solution containing 6, 9 and 12 vol% of desflurane for 10 min at each concentration. Systolic left ventricular pressure and rate of change of ventricular pressure (dp/dt) were measured. Heart rate and coronary flow were also measured. To differentiate direct vasodilatory effect of desflurane from an indirect metabolic effect due to autoregulation of coronary flow, oxygen delivery, myocardial oxygen consumption and percent oxygen extraction were calculated. Results: Heart rate (control 266+/-22 beats/min) decreased to 250+/-23 beats/min at 6 vol%, 236+/-26 beats/min at 9 vol% and 223+/-22 beats/min at 12 vol% of desflurane. Systolic left ventricular pressure and dp/dt decreased in a concentration-dependent manner. In spite of decrement of myocardial oxygen consumption, coronary flow (control 12.0+/-1.2 ml/min) increased to 12.8+/-1.6 ml/min at 6 vol%, 12.9+/-1.6 ml/min at 9 vol% and 13.7+/-1.4 ml/min at 12 vol% of desflurane. Oxygen delivery increased proportionally with coronary flow. Percent oxygen extraction decreased in a concentration-dependent manner. Conclusion: These results suggest that desflurane has a direct myocardial depressing and coronary vasodilating effect in a concentration-dependent manner.

PURPOSE: To describe the chest radiographic and CT findings of diffuse pulmonary hemorrhage. MATERIALS AND METHODS: Two radiologists retrospectively analysed the chest radiographic and CT findings of six patients withdiffuse pulmonary hemorrhage. Using open lung biopsy (n=2) and transbronchial lung biopsy or bronchoalveolarlavage (n=4), diagnosis was based on the presence of hemosiderin-laden macrophage or intra-alveolar hemorrhage.Underlying diseases were Wegener's granulomatosis (n=2), antiphospholipid antibody syndrome (n=2),Henoch-Schonlein purpura (n=1), and idopathic pulmonary hemosiderosis (n=1). In all patients, sequential chestradiographs, obtained during a one to six-month period, were available. HRCT scans were obtained in five patients,and conventional CT scans in one. Follow-up HRCT scans were obtained in two. We also analyzed the patterns ofinvolvement, distribution and sequential changes in the pulmonary abnormalities seen on chest radiographs and CTscans. RESULTS: Chest radiographs showed multifocal patchy consolidation (n=6), ground-glass opacity (n=3), andmultiple granular or nodular opacity (n=3). These lesions were intermingled in five patients, while in one therewas consolidation only. Sequential chest radiographs demonstrated the improvement of initial pulmonaryabnormalities and appearance of new lesions elsewhere within 5-6 days, though within 7-25 (average, 13) days,these had almost normalized. HRCT scans showed patchy consolidation (n=5), multiple patchy ground-glass opacity(n=5), or ill-defined air space nodules (n=4). These lesions were intermingled in five patients, and in one,ground-glass opacity only was noted. In two patients there were interlobular septal thickening and intralobularreticular opacity. The distribution of these abnormalities was almost always bilateral, diffuse with no zonalpredominancy , and spared the apex of the lung and subpleural region were less affected. CONCLUSION: Althoughchest radiographic and CT findings of diffuse pulmonary hemorrhage are nonspecific, sequential changes inbilateral multifocal patchy consolidation and ground-glass opacity, accompanied by clinical symptoms such ashemoptysis or anemia, may be helpful in the diagnosis of diffuse pulmonary hemorrhage.

PURPOSE: To evaluate the CT findings of tuberculous pericardial effusion. MATERIALS AND METHODS: In 12patients with tuberculous pericardial effusion. CT scans were obtained. The condition was diagnosed by thepresence of chronic granulomatous inflammation with caseous granuloma or acid fast bacilli in a biopsy specimen orpericardial fluid. CT findings were evaluated with regard to the appearance and the location of pericardialthickening, location of pericardial effusion, loculation of the pericardial effusion by adhesion of pericardiumand associated findings such as pulmonary tuberculosis or pleural effusion. RESULTS: In all cases, pericardialeffusion and thickening were seen. This thickening was usually even(10 of 12 cases), and occurred mainly in theanterior portion(7 of 12 cases). Thickened pericardium was enhanced and showed higher attenuation than adjacentchest wall muscle. Effusion was usually found in the anterior portion(10 of 12 cases), though the right and leftside were also involved(5/12 and 6/12 cases, respectively). Loculation of pericardial effusion was noted in tencases. Pleural effusion occurred in eight cases and associated active pulmonary tuberculosis in five. CONCLUSION: The CT findings of tuberculous pericardial effusion are enhanced evenly-thickened pericardium and anteriorloculated pericardial effusion, and are helpful for the diagnosis of tuberculous pericardial effusion.

BACKGROUND: A randomized, multicenter, open-label, parallel group study was performed to compare the effects of remifentanil and morphine as analgesic drugs on the duration of weaning time from mechanical ventilation (MV). METHODS: A total of 96 patients with MV in 6 medical and surgical intensive care units were randomly assigned to either, remifentanil (0.1-0.2 mcg/kg/min, n = 49) or morphine (0.8-35 mg/hr, n = 47) from the weaning start. The weaning time was defined as the total ventilation time minus the sum of controlled mode duration. RESULTS: Compared with the morphine group, the remifentanil-based analgesic group showed a tendency of shorter weaning time (mean 143.9 hr, 89.7 hr, respectively: p = 0.069). Secondary outcomes such as total ventilation time, successful weaning rate at the 7th of MV day was similar in both groups. There was also no difference in the mortality rate at the 7th and 28th hospital day. Kaplan-Meyer curve for weaning was not different between the two groups. CONCLUSIONS: Remifentanil usage during the weaning phase tended to decrease weaning time compared with morphine usage.

PURPOSE: This study investigated the effects of early enteral feeding on the morbidities of extremely low birth weight infants (ELBWI) weighing less than 1,000 g. METHODS: We conducted a retrospective review of the medical records of sixty one ELBWI who were admitted to the neonatal intensive care unit of Inje University Busan Paik Hospital from January 2007 to October 2009. ELBWI were divided into two groups; the control group included ELBWI from January 2007 to March 2008, for whom enteral feeding was started beyond 3 days and the early feeding group included ELBWI from April 2008 to October 2009, for whom enteral feeding was started within 3 days. RESULTS: Gestational age and birth weight did not differ between the two groups. In the early feeding group, start day of enteral feeding (control group vs. early feeding group; 7+/-2days vs. 2+/-1days), time to achieve full enteral feeding (68+/-6 days vs. 22+/-2 days), and the duration of parenteral nutrition (58+/-6 days vs. 22+/-2 days) were significantly shorter, and weight gain at postnatal day 28 was significantly higher than that of the control group (P<0.001). No differences were observed in the incidence of sepsis and necrotizing enterocolitis and duration of hospitalization; however, the incidence of total parenteral nutrition induced cholestasis (44% vs. 7%) and bronchopulmonary dysplsia (78% vs. 24%) was significantly lower in the early feeding group. CONCLUSION: Early enteral feeding in ELBWI shortened the time to achieve full enteral feeding, improved weight gain, and decreased the incidence of brochopulmonay dysplasia and cholestasis.
