RESUMEN

Pertussis is a pediatric infectious disease with one of the highest degrees of infectivity. Although pertussis may cause asymptomatic infections in children and adults with immunity, it can cause life-threatening diseases in newborn babies or infants. We report three cases of pertussis in infants <3 months of age without DTaP immunization who have received symptomatic treatment with the diagnosis of bronchiolitis from other hospitals, and subsequently correctly diagnosed and treated. The patients did not have the characteristic whooping cough, but the main symptoms were episodic cough, intermittent vomiting, and cyanosis. Based on culture results for Bordetella pertussis and PCR, pertussis was diagnosed and treated without any complications. As it is assumed that adults, adolescents, and asymptomatic patients may serve as sources of infection, immunization with Tdap vaccine is recommended to prevent dissemination of pertussis from adolescents and adults to infants, and thus maintain herd immunity.

RESUMEN

The purpose of this study was to identify the major etiological agents responsible for invasive bacterial infections in immunocompetent Korean children. We retrospectively surveyed invasive bacterial infections in immunocompetent children caused by eight major pediatric bacteria, namely Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Staphylococcus aureus, Streptococcus agalactiae, Streptococcus pyogenes, Listeria monocytogenes, and Salmonella species that were diagnosed at 18 university hospitals from 1996 to 2005. A total of 768 cases were identified. S. agalactiae (48.1%) and S. aureus (37.2%) were the most common pathogens in infants younger than 3 months. S. agalactiae was a common cause of meningitis (73.0%), bacteremia without localization (34.0%), and arthritis (50%) in this age group. S. pneumoniae (45.3%) and H. influenzae (20.4%) were common in children aged 3 months to 5 yr. S. pneumoniae was a common cause of meningitis (41.6%), bacteremia without localization (40.0%), and bacteremic pneumonia (74.1%) in this age group. S. aureus (50.6%), Salmonella species (16.9%), and S. pneumoniae (16.3%) were common in older children. A significant decline in H. influenzae infections over the last 10 yr was noted. S. agalactiae, S. pneumoniae, and S. aureus are important pathogens responsible for invasive bacterial infections in Korean children.

RESUMEN

PURPOSE: To describe the characteristics and incidence of neurologic complications related to the novel influenza A (H1N1) virus. METHODS: We reviewed the medical records of 752 children and adolescence (< or = 18 years of age) who had been diagnosed as novel influenza A (H1N1) infection through positive results of influenza A (H1N1) RT-PCR and hospitalized or visited the outpatient clinic and emergency department of Pusan National University Hospital from July 2009 to January 2011. RESULTS: We identified 15 patients who had experienced a neurologic symptom with a mean age of 8.8 years. There were 10 (66.7%) males and five (33.3%) females. Nine patients (60.0%) presented with seizures, two (13.3%) with decreased mentality, two (13.3%) with visual hallucination, and one (6.7%) with vertigo. The mean duration from onset of respiratory illness to the beginning of neurologic symptoms was 2 days (range: 0-4 days). Three patients (patient 2, 7, and 13) (20.0%) had abnormal results on cerebrospinal fluid analysis; however, novel influenza A (H1N1) was not detected. Further, one patient (6.7%) had abnormal MRI. Antiviral therapy (oseltamivir) was administered to fourteen patients (93%) and all patients recovered fully and had no neurologic sequelae. CONCLUSION: Novel influenza A (H1N1) was a cause of neurologic symptoms during the outbreak. Pediatricians should consider influenza virus infection in the differential diagnosis for children with neurologic symptoms during an epidemic of influenza.

RESUMEN

PURPOSE: To evaluate mortality and morbidity of very low birth weight infants(VLBW infants) born in the Busan area from 1996 to 2005. METHODS: A total of eight neonatal intensive care units (4 university hospitals and 4 general hospitals) in Busan participated in this study. A total of 1,414 VLBW infants were divided into three groups: period I, 1996 to 2000; period II, 1999 to 2002; period III, 2003 to 2005, based on date of birth. We performed a retrospective review of medical records of VLBWinfants and compared the survival rate, morbidity and mortality over the three periods. RESULT: The number of VLBW infants admitted to 8 NICUs in 1996-2005 was a total of 1,414 (1.3% incidence, mean gestational age 29.1+/-2.7 wk, mean birth weight 1158+/-235 g), including 361 (24.7%) extremely low birth weight infants (ELVW infants) who were less than 1,000 g at birth weight. Overall survival rate of VLBW infants was 66.1%. The survival rate of VLBW infants increased significantly over the three periods (period I:57.6%, period II:67.8%, period III:75.7%, P<0.01). Overall survival rate of ELBW infants was 33.8%, and increased from 26.4% in period I to 44.2% in period III (P<0.01). The incidence of respiratory distress syndrome was 45.1%; patent ductus arteriosus, 16.4%; bronchopulmonary dysplasia, 13.1%; blood culture positive sepsis, 12.7%; necrotizing enterocolitis, 6.6%; severe intracranial hemorrhage, 6.5%; and severe retinopathy of prematurity, 5.9%. The main causes of death were respiratory distress syndrome and sepsis. CONCLUSION: Overall survival rate of very low birth weight infant in Busan area during the last 10 years was 66.1%, and increased significantly over the three periods.

RESUMEN

PURPOSE: To evaluate mortality and morbidity of very low birth weight (VLBW) infants born in Busan from 1996 to 2001. METHOD: Seven neonatal intensive care units (including 3 university hospitals and 4 general hospitals) in Busan participated for this study. We performed retrospective review of 756 VLBW infants who were born in this area during study period was done to assess their mortality and morbidity. RESULT: The total number of VLBW infant was 756 (incidence: 0.97%, mean gestational age: 29.5 +/- 2.9 wk, mean birth weight: 1165+/-232 g) including 187 extremely low birth weight infants who were less than 1, 000 g birth weight (24.7%). The survival rate was 61.0% (461 of 756). It increased from 56.4% in early period (1996 to 1998) to 65.2% in late period (1999 to 2001) (P<0.01). The incidence of respiratory distress syndrome was 61.5% (466 of 756), patent ductus arteriosus 12.3% (93 of 756), blood culture positive sepsis 10.2% (77 of 756), bronchopulmonary dysplasia 9.3% (70 of 756), severe intracranial hemorrhage 6.5% (49 of 756), necrotizing enterocolitis 4.9% (37 of 756), severe retinopathy of prematurity 3.7 % (28 of 756). The main causes of death were respiratory distress syndrome and sepsis. CONCLUSION: The survival rate of VLBW infant in Busan area during recent 6 years was 61.0%, which is lower than other single unit result of our country, recent Japanese or North American data. We think both modernized facilities in NICU and well-trained medical personnel are needed to improve survival.

RESUMEN

Pulmonary lymphangiectasis is relatively a rare disorder. This disorder can be divided into three groups. First, pulmonary abnormality is associated with lymphangiectasia in other viscera (especilly intestine) and extremities. In the second group, patients have a concomitant cardiac anomaly, which appears to be associated with obstructed pulmonary venous return. The third group comprises of patients whose lymphangicetasia is not associated with cardiac anomalies. This form is thought to result from abnormal development of the lung. In this case, a 6-year-old male who was previously diagnosed as lymphedema of extremities and intestinal lymphangiectasis, suffered from coughing and dyspnea repeatedly. High resolution computed tomography showed thickening of bronchovascular bundle and interlobular septa, pneumonic consolidation and pleural effusion. These findings were compatible with pulmonary lymphangiectasis. We report a case of pulmonary lymphangiectasis with brief review of literatures.
