Background: This meta-analysis was performed to examine the association between maternal hypertension during pregnancy (HDP) and neonatal bronchopulmonary dysplasia (BPD). Methods: We systematically searched PubMed, EMBASE, the Cochrane Library, and the KoreaMed database for relevant studies. We used the Newcastle-Ottawa Scale for quality assessment of all included studies. The meta-analysis was performed using Comprehensive Meta-Analysis software (version 3.3). Results: We included 35 studies that fulfilled the inclusion criteria; the total number of infants evaluated came to 97,399 through review process. Maternal HDP was not significantly associated with any definition of BPD, i.e., oxygen dependency at 36 weeks of gestation (odds ratio [OR], 1.162; 95% confidence interval [CI], 0.991–1.362; P = 0.064) in pooled analysis of 29 studies or oxygen dependency at 28 days of age (OR, 1.084; 95% CI, 0.660–1.780; P = 0.751) in pooled analysis of 8 studies. Maternal HDP was significantly associated only with severe BPD (OR, 2.341; 95% CI, 1.726–3.174; P < 0.001). BPD was not associated with HDP in the overall analysis (OR, 1.131; 95% CI, 0.977–1.309; P = 0.100) or subgroup analysis according to the definition of HDP. Conclusion Maternal HDP was not associated with neonatal BPD defined by the duration of oxygen dependency (at either 36 weeks of gestation or 28 days of life) but was associated with severe BPD.

Purpose: Atrial flutter is an uncommon arrhythmia in the neonatal period. This study aimed to describe the cause and clinical course of atrial flutter in neonates. Methods: The medical records of 14 patients diagnosed with atrial flutter at Ulsan University Hospital Neonatal Intensive Care Unit (NICU) between March 2008 and August 2020 were reviewed retrospectively. Results: All 14 cases occurred on the first day of birth. Of these, two were term infants, and 12 were preterm infants. Causes of atrial flutter included three cases of the umbilical venous catheter misplacement, one with a diabetic mother, and one ivolving atrial flutter after an intravenous aminophylline injection. Thirteen patients had structurally normal hearts with no congenital heart diseases. The patient, born to a diabetic mother, had an atrial septal defect and ventricular hypertrophy. Adenosine was administered first to differentiate it from paroxysmal supraventricular tachycardia. Synchronized cardioversion was attempted in 11 patients, while one received it after an esmolol injection that failed to convert to sinus rhythm. One patient had a recurrence after the intrusion of a peripherally inserted central catheter; however, atrial flutter disappeared after repositioning it. No patient had a recurrence after discharge. Conclusion Neonatal atrial flutter is a rare tachyarrhythmia with the risk factors often unknown; however, it could occur in structural heart disease, mispositioning of the umbilical venous catheter, and if the mother has diabetes. During umbilical venous catheterization, clinicians should be cautious and ensure appropriate monitoring of infants in the NICU as it may cause complications.

Purpose: Intussusception is the most common cause of bowel obstruction in children; however, it is rarely diagnosed in newborn infants. This study aimed to describe the clinical features of intussusception in newborn infants. Methods: Medical records of eight patients diagnosed with intussusception during the newborn period at Ulsan University Hospital between March 2007 and March 2020 were retrospectively reviewed. Results: Among the eight cases, two occurred in the intrauterine period and six occurred in the postnatal period. Intrauterine intussusception presented with symptoms of bowel obstruction within 1 to 2 days after birth, and ileal atresia was diagnosed simultaneously through exploratory laparotomy. All the postnatal patients were extremely low birth weight infants (median gestational age and birth weight: 25+6 weeks and 745 g, respectively). Four cases were diagnosed preoperatively using abdominal ultrasonography. One patient was diagnosed by exploratory laparotomy because the clinical symptoms were nonspecific and difficult to differentiate from those of necrotizing enterocolitis, a more prevalent complication in preterm infants. The site of intussusception in all six patients was the small bowel. Meckel’s diverticulum (one case) and meconium obstruction (two cases) were found to be the lead point. Conclusion Neonatal intussusception tends to show different clinical features according to its period of occurrence. Intussusception, especially in preterm infants, has nonspecific clinical features; therefore, clinicians should always be cautious of this disease for its early diagnosis.

Epithelial ovarian carcinoma is a high mortality neoplasm in gynecologic malignancy. It usually can metastasize to distant organs such as pleura, liver, lung, and lymph nodes. However, the skin metastases are not common and related to very poor prognosis. Here we report a 54-year-old patient with ovarian clear cell carcinoma with skin metastases on the anterior chest at 11 months after initial diagnosis. Although she received palliative chemotherapy, she expired due to disease progression 2 months later after the diagnosis of skin metastases.

The use of caffeine citrate for treatment of apnea in very low birth weight infants showed short-term and long-term benefits. A systematic review and meta-analysis of the literature was undertaken to document the effect providing caffeine early (0-2 days of life) compared to providing caffeine late (> or =3 days of life) in very low birth weight infants on several neonatal outcomes, including bronchopulmonary dysplasia (BPD). We searched MEDLINE, the EMBASE database, the Cochrane Library, and KoreaMed for this meta-analysis. The quality of the included studies was assessed using the Newcastle-Ottawa Scale and Jadad's scale. Studies were included if they examined the effect of the early use of caffeine compared with the late use of caffeine. Two reviewers screened the candidate articles and extracted the data from the full-text of all of the included studies. We included a total of 59,136 participants (range 58,997-59,136; variable in one study) from a total of 5 studies. The risk of death (odds ratio [OR], 0.902; 95% confidence interval [CI], 0.828 to 0.983; P=0.019), bronchopulmonary dysplasia (BPD) (OR, 0.507; 95% CI, 0.396 to 0.648; P<0.001), and BPD or death (OR, 0.526; 95% CI, 0.384 to 0.719; P<0.001) were lower in the early caffeine group. Early caffeine use was not associated with a risk of necrotizing enterocolitis (NEC) and NEC requiring surgery. This meta-analysis suggests that early caffeine use has beneficial effects on neonatal outcomes, including mortality and BPD, without increasing the risk of NEC.

PURPOSE: Anogential distance (AGD) and the 2:4 digit length ratio appear to provide a reliable guide to fetal androgen exposure. We intended to investigate the current status of penile size and the relationship between penile length and AGD or digit length according to birth weight in Korean newborn infants. MATERIALS AND METHODS: Between May 2013 and February 2014, among a total of 78 newborn male infants, 55 infants were prospectively included in this study. Newborn male infants with a gestational age of 38 to 42 weeks and birth weight>2.5 kg were assigned to the NW group (n=24) and those with a gestational age<38 weeks and birth weight<2.5 kg were assigned to the LW group (n=31). Penile size and other variables were compared between the two groups. RESULTS: Stretched penile length of the NW group was 3.3+/-0.2 cm, which did not differ significantly from that reported in 1987. All parameters including height, weight, penile length, testicular size, AGD, and digit length were significantly lower in the LW group than in the NW group. However, there were no significant differences in AGD ratio or 2:4 digit length ratio between the two groups. CONCLUSIONS: The penile length of newborn infants has not changed over the last quarter century in Korea. With normal penile appearance, the AGD ratio and 2:4 digit length ratio are consistent irrespective of birth weight, whereas AGD, digit length, and penile length are significantly smaller in newborns with low birth weight.

PURPOSE: This study investigated the risks of development and surgical complications of meconium obstruction (MO) in very low birth weight (VLBW) infants. METHODS: We performed a retrospective medical record review of VLBW infants admitted to the neonatal intensive care unit of Haeundae Paik hospital and diagnosed with MO of prematurity (MOP) between March 2010 and August 2013. RESULTS: Of 267 VLBW infants admitted to the neonatal intensive care unit, 28 were diagnosed with MOP. Perinatal factors including maternal pregnancy-induced hypertension and small for gestational age were associated with MOP development (P<0.05). Over two-thirds of VLBW infants with MOP were successfully treated with a gastrografin enema. The remaining eight VLBW infants required surgery. Although small for gestational age was more frequent in the medical treatment group, specific risk factors associated with MOP development did not affect the need for surgical intervention. CONCLUSION: MOP is common in VLBW infants, as most VLBW infants have risk factors for MOP. Identifying risk factors permits early diagnosis and initiation of appropriate medical treatment, reducing the necessity for surgery. However, the presence of specific risk factors does not increase risk of surgical complications.

Hypereosinophilic syndrome (HES) is defined as peripheral eosinophilia, organ involvement of eosinophils and exclusion of other disorders or dysfunction. HES is subclassified as myeloproliferative variant, T-lymphocytic, overlap, idiopathic, familial and associated type according to the new classification using molecular and immunologic markers. HES presenting with gastrointestinal symptoms is very rare but characterized by peripheral eosinophilia, eosinophilic infiltration of the gastrointestinal tract with other organs such as liver and bone marrow. We report a rare case of idiopathic HES in 18-year-old adolescent who presented with gastrointestinal symptoms including abdominal pain, diarrhea and ascites which resolved rapidly with corticosteroid therapy. HES should be included in the differential diagnosis of abdominal pain and ascites in children and adolescents.
