RESUMO
Nocturnal enuresis (NE) is a common problem among 10% school-aged children. The etiologies underlying childhood NE is complex and not fully understood nowadays. Nevertheless, increasing evidence suggests a potential link between neurobehavioral disorders and enuresis in children. In this study, we aimed to explore novel metabolomic insights into the pathophysiology of NE and also, its association with pediatric psychiatric problems. Urine collected from 41 bedwetting children and 27 healthy control children was analyzed by using 1H-nuclear magnetic resonance spectroscopy from August 2017 to December 2018. At regular follow-up, there were 14 children with refractory NE having a diagnosis of attention deficient hyperactivity disorder (ADHD) or anxiety. Eventually, we identified eight significantly differential urinary metabolites and particularly increased urinary excretion of betaine, creatine and guanidinoacetate linked to glycine, serine and threonine metabolism were associated with a comorbidity of neurobehavioral disorders in refractory bedwetting children. Notably, based on physiological functions of betaine acting as a renal osmolyte and methyl group donor, we speculated its potential role in modulation of renal and/or central circadian clock systems, becoming a useful urinary metabolic marker in diagnosis of treatment-resistant NE in children affected by these two disorders.

The aim of this study was to identify the clinical parameters indicative of serious etiology of neonatal hyperthermia and to determine the appropriate cutoff value of body temperature (BT) for predicting the need to transfer the newborn to the special care (SC) nursery.The nursery records of newborns diagnosed with hyperthermia between 2007 and 2013 were retrospectively reviewed. The clinical characteristics of newborns with hyperthermia remained in the nursery were compared with those transferred to the SC nursery. In addition, the receiver operating characteristic analysis was used to determine the appropriate cutoff BT for predicting further septic workup in the SC nursery.Among the 92 newborns with hyperthermia evaluated, 30 (32.6%) were transferred to the SC nursery and 62 (67.4%) remained in the nursery. Clinical characteristics associated with transfer to the SC nursery included the highest BT, BT at first measurement during hyperthermia, frequency of hyperthermia, duration of hyperthermia, irritable crying, decreased appetite, poor activity, vomiting with abdominal distension, tachypnea, and tachycardia (all Pâ<â.05). BT for predicting the need for transferring newborns with hyperthermia to the SC nursery had an area under the curve of 0.976 (Pâ<â.001). A BT of 38â°C was determined as the optimal cutoff value for predicting the need to monitoring for suspicious clinical symptoms (sensitivity (Sn), 93%; specificity (Sp), 87%). Furthermore, BT≥38.2â°C (Sn, 70%; Sp 100%) and BT≤37.8â°C (Sn, 100%; Sp, 61%) respectively were determined as the cutoff values for transferring newborns to the SC nursery or allowing them to remain in the regular nursery.Our results suggest a BT of 38â°C represents the optimal cutoff indicating newborns for close monitoring for suspicious clinical presentations including irritable crying, decreased appetite, poor activity, vomiting with abdominal distension, tachypnea, and tachycardia. Newborns with BTâ<â37.8â°C may remain in the nursery but should be transferred to the SC nursery for septic workup and empiric antibiotics if the BT is above 38.2â°C.

BACKGROUND: Abdominal pain is one of the most common complaints made by patients visiting emergency departments; however, ovarian torsion is an uncommon cause of abdominal pain, especially in young children. Early diagnosis is essential in order to salvage the ovaries. We performed a retrospective analysis of patients under 18 years of age who visited Changhua Christian Hospital with adnexal torsion between June 2003 and June 2010. METHODS: Medical records were reviewed for age, associated symptoms, past and present medical histories, physical findings, diagnostic tests performed, clinical course, pathological findings, and diagnoses. RESULTS: A total of 21 patients were identified and included in the analysis; their mean (SD) age was 13.62 (3.75) years. Abdominal pain was the universal symptom. Vomiting or nausea was the second most common symptom (33.3%). The average period between symptom onset and diagnosis was 3.29 (6.39) days. Right-side adnexal torsion occurred in 14 patients, and left-side torsion in seven patients. Ovarian cysts, most often dermoid cysts (e.g., teratomas), were found in 16 patients (76%). Except for one conservatively treated case and one malignant case (adult granulose cell tumor), the other results of the pathological examination were as follows: eight dermoid cysts, two cystadenomas, one follicular cyst, and eight simple cysts. CONCLUSION: Although it is uncommon, adnexal torsion should be included in the differential diagnosis of lower abdominal pain in all girls, regardless of age. Sonography is helpful for making such a diagnosis. Time is a critical factor, and early laparoscopy or laparotomy may save a viable ovary.

People with type 1 diabetes mellitus are at an increased risk of cardiovascular mortality. Studies comparing arterial stiffness between subjects with type 1 diabetes and nondiabetic controls have provided controversial findings.We investigated brachialankle pulse wave velocity (baPWV) in 87 teenagers with type 1 diabetes mellitus and in 21 matched healthy controls. Our data show that baPWV was not increased in teenagers after a median illness of 5 years.

BACKGROUND: Empiric antibiotics are frequently given for children with acute exudative tonsillitis. A few studies have investigated the causative agent of acute "exudative" tonsillitis in children to evaluate the necessity of antibiotic therapy. This study tried to explore the common causative agent of acute exudative tonsillitis among children. METHODS: From April 2009 to March 2010, throat swabs were obtained and cultured for viruses and bacteria from children who visited the pediatric emergency rooms of two medical centers in central Taiwan with acute exudative tonsillitis. Demographic data and microbiological results were analyzed. RESULTS: A total of 294 children with acute exudative tonsillitis were enrolled during the 1-year prospective study, and 173 (58.8%) of them were younger than 7 years. Group A streptococci were isolated from only three (1.0%) children, and they were all older than 6 years. A total of 143 viruses were isolated from 140 (47.6%) children. Adenovirus (18.7%) and enterovirus (16.3%) were the most common viral etiologies, followed by influenza virus (5.4%), parainfluenza virus (5.1%), herpes simplex virus Type 1 (2.7%), and respiratory syncytial virus (0.3%). Group A streptococcus only contributed to a minimal portion of acute exudative tonsillitis. CONCLUSION: Routine or immediate antibiotic therapy for acute exudative tonsillitis in children is not necessary.

Acute poststreptococcal glomerulonephritis (APSGN) is the most common form of postinfectious nephritis worldwide. The relationship between inflammation and arterial stiffness has been described elsewhere, but there have been no studies that have analyzed the association between arterial compliance and APSGN. The aim of this study is to assess brachial-ankle pulse wave velocity (baPWV) in pediatric patients with APSGN, and the value of baPWV in predicting the outcome. We evaluated 16 children diagnosed with APSGN, 11 children with acute pyelonephritis (APN), and 25 healthy individuals in our hospital. The baPWV of all candidates was measured. In addition, follow-up of the APSGN group was conducted for baPWV, blood pressure and biochemical parameters. Significantly increased baPWV was observed in the APSGN group at initial diagnosis (P<0.001), in comparison with the APN group and healthy controls. Of these, 13 patients received sequential measurement of baPWV. Overwhelmingly, baPWV was rapidly normalized in 11 patients, whereas 2 boys presented with persistently higher baPWV. During the follow-up period of 2-3 years, both had consistency of proteinuria, and consequently, they progressed to either chronic renal insufficiency or end-stage renal disease (ESRD). In conclusion, the results demonstrate that APSGN involves not only the kidney, but also the arteries outside the kidney. Acute arterial stiffness might persist in patients who do not recover, but develop chronic kidney disease (CKD).

BACKGROUND AND PURPOSE: In a previous study, we found that wheezing children in rural central Taiwan had a significantly lower average sensitization rate to Dermatophagoides pteronyssinus (Der p) than those in Taipei city. We propose that Blomia tropicalis (Blo t) might be the major mite allergen in rural central Taiwan. METHODS: Using the preserved sera from our previous study, we retrospectively measured specific immunoglobulin E (IgE) antibody to Blo t and analyzed the correlation between Blo t and Der p in wheezing children in rural central Taiwan. A total of 2206 children with physician-diagnosed asthma and wheezing were enrolled and categorized among five age groups. The sensitization rate and level of specific IgE antibody to Blo t were analyzed. RESULTS: The age-specific sensitization rates and the level of specific IgE antibody to either Blo t or Der p increased progressively with increasing age, being greatest in the age group 8 to 12 years. A significant positive correlation existed between sensitization rate and age for both Blo t and Der p (p=0.001). Specific IgE antibody to Blo t was undetectable in patients younger than 1.5 years. A significant positive correlation also existed between age and anti-Blo t IgE antibody level (p<0.003). However, the allergen-specific IgE level was lower for Blo t than Der p (p<0.005) in all age groups. CONCLUSIONS: Blo t might be the major mite allergen to associated with early wheeze and atopic asthma in rural central Taiwan.
