A 5-year-old male Pointer dog weighing 24 kg was referred because of a chronic cough. The dog was routinely vaccinated and treated monthly with medications to prevent heartworm and endoparasites. Blood analyses revealed no abnormalities. Chest radiographs showed interstitial and bronchial patterns in the caudal lung fields. Bronchoscopic imaging identified a collapse of the left bronchus with a mucopurulent discharge, indicating the onset of bronchomalacia. Computed tomography also showed bronchial collapse and a tapering angle in the left caudal bronchus. This case study describes the diagnosis of bronchomalacia in a Pointer dog with a chronic cough, and suggests that bronchoscopic examination is a valuable tool for identifying of the onset of bronchomalacia in dogs presenting with an uncontrolled cough.

Postpneumonectomy syndrome is a rare complication that usually occurs in younger patients within the first year after a right total lung resection. Its clinical presentations are stridor, dyspnea, and recurrent pulmonary infections. An airway obstruction secondary to the extreme mediastinal shift and ratation after a pneumonectomy is the main mechanism. It is commonly complicated with tracheobronchomalacia due to longstanding airway compression. The management modalities involve a repositioning of the mediastinum with volume expansion of the pneumonectomy site by a expandable prosthesis. however, other methods including an endobronchial stent insertion should be considered in the presence of a tracheobronchomalacia or in poor surgical candidates. Here we describe a case of postpneumonectomy syndrome complicated by a bronchomalacia, which was successfully treated with a self-expandable endobronchal stent.

Purpose: To evaluate the impact of delayed interval delivery on neonatal outcomes. Methods: This was a retrospective study of infants who were born at Seoul National University Hospital by delayed interval delivery from June 2005 to July 2010. Outcomes (neonatal mortality and morbidity) of later babies were compared to those of the first babies and the control group whose gestational ages and birth weights were similar to them. Results: There were 4 twin and 5 triplet pregnancies. The first babies (group 1, n=9) were delivered at $22^{+6}$ to $27^{+5}$ weeks of gestational age, and the later babies (group 2, n=14) were born at $24^{+6}$ to $28^{+0}$ weeks. The mean interval between the first and later deliveries was 10 days, and there was no delay between the second and third deliveries in all triplet pregnancies. There were more small for gestational age (SGA) infants in group 1 than group 2 (66.7% and 21.4% respectively, P=0.03). Two of three babies who died in group 1 were born before 24 weeks of gestational age and expired within a week after birth. The mortality rate of group 2 (7.1%) was lower than group 1 (33.3%), but not significantly (P=0.106). The control group matched to group 2 consisted of 28 infants. There were no significant differences in neonatal mortality and morbidity between the two groups. Conclusion: Although there is a limitation to the number of infants in this study, it suggested that delayed delivery in a multiple pregnancy could decrease the incidence of SGA of the remaining fetuses and that prolonged gestation would not be harmful to those fetuses after birth.

Purpose : With the recent improved survival of extremely low birth weight infants(ELBWI), enteral feeding has become a major issue. This study investigates the effects of early enteral feeding in ELBWI on their morbidity, duration of hospitalization, and mortality. Methods : ELBWI admitted to the neonatal intensive care unit at Samsung Medical Center from November 1994 to April 2004 who survived more than 14 days were enrolled. ELBWI were divided into two groups : an early feeding group(EF), in which enteral feeding was started within 3 days after birth; and a late feeding group(LF), in which enteral feeding was started beyond 3 days after birth. 80 ELBWI came under EF, and 131 ELBWI under LF. Results : Birth weight and gestational age did not differ between the two groups. In EF, the time to achieve full enteral feeding and the duration of parenteral nutrition were significantly shorter than in LF. The incidence of bronchopulmonary dysplasia was significantly lower in EF, but the incidences of sepsis, necrotizing enterocolitis, and cholestasis were not different between the two groups. There was no difference in the survival rate between the two groups, but the duration of hospitalization was significantly shorter in EF. Conclusion : Early enteral feeding in ELBWI did not increase the incidence of necrotizing enterocolitis and sepsis, but rather decreased the incidence of bronchopulmonary dysplasia and shortened the duration of hospitalization.
