Epidermal nevi are benign congenital hamartomas derived from the embryonal ectoderm. They may also be associated with anomalies of musculoskeletal, nervous, ocular, and rarely cardiovascular and urogenital system in an epidermal nevus syndrome. To find out these abnormalities, careful history taking, thorough physical evaluation, and long-term follow-up are advisable in a patient with wide spread epidermal nevus. We report a case of diffuse epidermal nevi involving the scalp, face, trunk, and limbs in a newborn.

BACKGROUND: Serum lactate is a potentially useful biomarker to risk-stratify patients with severe sepsis and septic shock. However, there are only a few studies on the association of serum lactate levels and prognosis in septic shock patients with initial low lactate levels. METHODS: To evaluate whether initial and follow-up lactate levels associated with mortality in septic shock patients with low lactate level, we conducted a retrospective observational study of patients with septic shock, who were hospitalized through the emergency department in February-July 2008. Initial lactate level was stratified as low (<4 mmol/L) or high (> or =4 mmol/L). The primary outcome was 28-day mortality and multiple logistic regression analysis was used to adjust for potential confounders in the association between lactate clearance and mortality. RESULTS: Of 90 patients hospitalized with septic shock during the study period, 68 (76%) patients had low initial lactate. Mortality at 28 days was 18% in patients with low lactate level. In these patients, initial lactate level was not associated with mortality (p = 0.590). However, increased lactate at follow-up and lactate clearance were associated with mortality (p = 0.006, p = 0.002, respectively). In a multiple logistic regression analysis, increased mortality rate independently associated with age (OR 1.162, 95% CI 1.041-1.298) and lactate clearance (OR 0.654, 95% CI 0.498-0.859). CONCLUSIONS: In septic shock patients with a low lactate level, lactate clearance independently associated with a decreased mortality rate. Therefore, lactate clearance could be useful for predicting the outcome in these patients.

PURPOSE: This study was performed to characterize sepsis with thrombocytopenia in premature infants to determine if thrombocytopenia is a prognostic factor in sepsis in premature infants. METHODS: We retrospectively analyzed the medical records of sepsis in premature infants admitted to the neonatal intensive care unit(N=41) at the Hallym University Sacred Heart Hospital from January 1999 to December 2002. The incidence, risk factors, symptoms, hematologic and bacteriologic findings were analyzed during episodes of sepsis. RESULTS: Of the 41 cases, 29(72%) were associated with thrombocytopenia. The ratio of male to female was 1.2 : 1. The vast majority(98%) were late-onset sepsis. The risk factors of the thrombocytopenic group were low birth weight and low gestational age. Major symptoms were poor activity (72%), apnea/tachypnea(52%), but were not significantly different between two groups. In the thrombocytopenic group(N=29), low total WBC count and high CRP level were discovered(P=0.03, P<0.01). The mean platelet count was 70.17(x103/mm3) at diagnosis of sepsis, and a mean platelet nadir was 43.10(x103/mm3). The severe thrombocytopenia(below 50x103/mm3) in the thrombocytopenic group was discovered in 69% and the duration of thrombocytopenia was about eight days. The majority of pathogens were gram-negative bacteria and candida. The thrombocytopenic group showed a pro longed length of stay and a high mortality rate. According to comparisons between the survived and expired groups, low birth weight, low gestational age, neutropenia and thrombocytopenia were significantly correlated with mortality(P<0.05). CONCLUSION: The sepsis with thrombocytopenia in premature infants showed late-onset sepsis and high morbidity and mortality, although differences were not significant statistically. Especially, low birth weight and low gestational aged infants should be cautiously treated and monitored.

Background: We evaluated the long-term effects of domiciliary noninvasive positive-pressure ventilation (NIPPV) used to treat patients with chronic obstructive pulmonary disease (COPD). Methods: Databases were searched to identify randomized controlled trials of COPD with NIPPV for longer than 1 year. Mortality rates were the primary outcome in this meta-analysis. The eight trials included in this study comprised data from 913 patients. Results: The mortality rates for the NIPPV and control groups were 29% (118/414) and 36% (151/419), suggesting a statistically significant difference (risk ratio [RR], 0.79; 95% confidence interval [CI], 0.65–0.95). Mortality rates were reduced with NIPPV in four trials that included stable COPD patients. There was no difference in admission, acute exacerbation and quality of life between the NIPPV and control groups. There was no significant difference in withdrawal rates between the two groups (RR, 0.99; 95% CI, 0.72–1.36; p=0.94). Conclusion Maintaining long-term nocturnal NIPPV for more than 1 year, especially in patients with stable COPD, decreased the mortality rate, without increasing the withdrawal rate compared with long-term oxygen treatment.

Esophageal perforation, a well-known entity in adults, is relatively uncommon in infants and children. Aggressive management in neonatal intensive care units have led to increased survival of premature infants and very sick babies. But it have led to unusual complication like iatrogenic perforation. Perforation of the esophagus or pharynx may occur during replacement of endotracheal or nasogastric tubes in the newborn infant. We recently experienced a case of esophageal perforation presenting with pneumomediastinum in premature infant, which was induced by gastric tube insertion and managed medically. We think that prevention is more important. So, careful visualization of vocal cord during intubation, gentle laryngoscopy, and the use of a soft rubber catheter for oral suction are needed.

Tuberculosis remains as a major public health problem worldwide. In addition to classic pulmonary tuberculosis, tuberculosis may sometimes present atypically. In the case of atypical tuberculosis, the unusual sites and properties that mimic other diseases can lead to a misdiagnosis and therapeutic delay. Abdominal and pharyngeal tuberculosis are uncommon extrapulmonary manifestations of tuberculosis. To the best of our knowledge, a combination of abdominal and pharyngeal tuberculosis with endobronchial tuberculosis has not been reported. We report a case of concurrent abdominal and pharyngeal tuberculosis in a patient with chronic endobronchial tuberculosis mimicking a metastatic malignancy on computed tomography and FDG-PET.

Malignant coloenteric fistula is a rare complication of colon cancer. Colon carcinoma is the most common etiology of this entity. Clinical features are diarrhea, weight loss, anemia and feculent vomiting. The diagnosis is most often made by barium enema examination. The primal therapy is operation. We present a case of a 51-year old male in whom a coloenteric fistula caused by transverse colonic carcinoma. He complained of abdominal pain, diarrhea and dizziness. UGI series demonstrated a fistulous track between colon and small bowel. On abdominal CT examination, a mass involving hepatic flexure of colon with a fistulous tract and metastatic nodules in right lobe of liver were found. Colonoscopy revealed a circumferential mass and the orifice of the fistula. The patient refused operation and expired one month after discharge.

Background: Successful liberation from mechanical ventilation is one of the most crucial processes in critical care, because it is the first step through which a respiratory failure patient begins to transition out of the intensive care unit, and return to normal life. Therefore, when devising appropriate strategies for removing mechanical ventilation, it is essential to consider scientific and systematic approaches, as well as the individual experiences of healthcare professionals. Recently, numerous studies have investigated methods and tools to identify when mechanically ventilated patients are ready to breathe on their own. The Korean Society of Critical Care Medicine therefore provides these recommendations to clinicians for liberation from the ventilator. Methods: Meta-analyses and comprehensive syntheses were used to thoroughly review, compile, and summarize the complete body of relevant evidence. All studies were meticulously assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) method, and the outcomes were presented succinctly as evidence profiles. These evidence syntheses were discussed by a multidisciplinary committee of experts in mechanical ventilation, who then developed and approved the recommendations. Results: Recommendations for nine questions on ventilator liberation about Population, Intervention, Comparator, and Outcome (PICO) are presented in this document. This guideline presents seven conditional recommendations, one expert consensus recommendation, and one conditional deferred recommendation. Conclusion We developed these clinical guidelines for mechanical ventilation liberation to provide meaningful recommendations. These guidelines reflect the best treatment for patients seeking liberation from mechanical ventilation.
