Hypertension and prehypertension among adolescents in secondary schools in Enugu,South East Nigeria

Background

Hypertension is a prevalent cardiovascular disease risk factor among blacks and adolescent hypertension can progress into adulthood.

Objective

To determine the prevalence of hypertension and prehypertension among secondary school adolescents in Enugu South East Nigeria.

Methodology

A study of 2694 adolescents aged 10-18 years in Enugu metropolis was carried out. Socio-demographic profile anthropometric and blood pressure readings were obtained. Derived measurements such as Prehypertension, hypertension and BMI were obtained.

Results

The results showed that the mean systolic blood pressure and diastolic blood pressure for males were 106.66+ 11.80 mmHg and 70.25 + 7.34 mmHg respectively. The mean SBP and DBP for females were 109.83+ 11.66 mmHg and 72.23 + 8.26 mmHg respectively (p < 0.01). Blood pressure was found to increase with age. Prevalence of hypertension and prehypertension was 5.4% and 17.3% respectively with a higher rate in females (6.9%) than males (3.8%). Prevalence of prehypertension among males and females were 14.3% and 20.1% respectively. The prevalence of obesity was 1.9%.

Conclusion

Modifiable risk factors exist among adolescents. Early lifestyle modification and a strengthened school health are recommended.

     

Long-term outcome and need of re-operation in gastro-esophageal reflux surgery in children

Background

Fundoplication is considered a mainstay in the treatment of gastro-esophageal reflux. However, the literature reports significant recurrences and limited data on long-term outcome.

Aims

To evaluate our long-term outcomes of antireflux surgery in children and to assess the results of redo surgery.

Methods

We retrospectively analyzed all patients who underwent Nissen fundoplication in 8 consecutive years. Reiterative surgery was indicated only in case of symptoms and anatomical alterations. A follow-up study was carried out to analyzed outcome and patients’ Visick score assessed parents’ perspective.

Results

Overall 162 children were included for 179 procedures in total. Median age at first intervention was 43 months. Comorbidities were 119 (73 %), particularly neurological impairments (73 %). Redo surgery is equal to 14 % (25/179). Comorbidities were risk factors to Nissen failure (p = 0.04), especially children suffering neurological impairment with seizures (p = 0.034). Follow-up datasets were obtained for 111/162 = 69 % (median time: 51 months). Parents’ perspectives were excellent or good in 85 %.

Conclusions

A significant positive impact of redo Nissen intervention on the patient’s outcome was highlighted; antireflux surgery is useful and advantageous in children and their caregivers. Children with neurological impairment affected by seizures represent significant risk factors.

     

Pediatric Asthma and Food Allergy

Objective

To quantitatively summarize the evidence from observational studies on the relation between pediatric asthma and food allergy.

Methods

A literature search was conducted in Medline and EMBASE (August 2016). Two independent reviewers appraised the studies and extracted the estimates of interest. Methodological quality of the included studies was assessed using National Heart Lung and Blood Institute (NHLBI) Quality Assessment Tools. Data were pooled using random-effects meta-analysis.

Results

A total of 32 relevant studies were identified but only 8 studies met the inclusion criteria. Using random-effect model, food allergy showed strong association with asthma in children (OR = 2.87 [95% CI: 2.05–4.00]; P < 0.0001).

Conclusions

This study suggested that food allergy is associated with an increased risk of asthma in children.

     

Current practice regarding timing of patent processus vaginalis ligation for idiopathic hydrocele in young boys: a survey of UK surgeons

Purpose

The aim of this study was to determine the current UK practice regarding timing of surgical repair of hydroceles in young boys.

Methods

Through a validated, online survey, participants were asked their preferred management option in five different clinical scenarios across five age ranges.

Results

71 responses were included in the analysis. The most common age to offer surgical intervention for a congenital hydrocele that is stable or increasing in size, or a hydrocele of the cord is 24–36 months. For a stable hydrocele presenting after 12 months of age, the most common age to offer repair is between 36 and 48 months. Approximately ¼ of respondents defer surgery until 4 years of age for any stable hydrocele. For a congenital hydrocele that is decreasing in size, the majority of respondents (57%) do not offer surgical intervention even over 4 years of age. The majority of respondents (61%) do not differentiate between communicating and non-communicating hydroceles when considering age for repair.

Conclusion

These results suggest that there is uncertainty regarding the optimum age for PPV ligation and adequate underlying variability in practice to support a prospective study of the optimum age for hydrocele repair and the natural history of PPV closure.

     

Serum proteomic profiling for autism using magnetic bead-assisted matrix-assisted laser desorption ionization time-of-flight mass spectrometry: a pilot study

Background

The pathogenesis of autism spectrum disorders remains elusive and currently there are no diagnostic or predictive biomarkers in autism available. Proteomic profiling has been used in a wide range of neurodevelopmental disorder studies, which could produce deeper perceptions of the molecular bases behind certain disease and potentially becomes useful in discovering biomarkers in autism spectrum disorders.

Methods

Serum samples were collected from autistic children about 3 years old in age (n = 32) and healthy controls (n = 20) in similar age and gender. The samples were identified specific proteins that are differentially expressed by magnetic bead-based pre-fractionation and matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-ToF-MS).

Results

Eight protein peaks were significantly different in autistic children from the healthy controls (P < 0.0001). The two peaks with the most significant differences were 6428 and 7758 Da in size.

Conclusion

According to differences in serum protein profiles between the autistic children and healthy controls, this study identified a set of differentially expressed proteins those are significant for further evaluation and might function as biomarkers in autism.

     

Differential learning processes for laparoscopic and open supraumbilical pyloromyotomy

Purpose

To compare the learning curves for mastering OP and LP surgical techniques, in terms of effects on completion times and postoperative outcomes/complications.

Methods

A retrospective analysis was performed for 198 patients with hypertrophic pyloric stenosis. The learning curves were in regard to two groups of surgeons: three of whom performed 106 OPs while three others performed 92 LPs. Treatment-related complications were divided into two categories: specific complications relating to the pyloromyotomy and non-specific complications. A logistic regression model with repeated data was used to explore the occurrence of complications.

Results

The overall postoperative complication rates were not significantly different between the OP (15.1 %) and the LP (11.8 %) groups. Specific complications were more frequent in the LP group (6.4 versus 2.8 %), while non-specific complications were more frequent in the OP group (12.1 versus 5.3 %). The occurrence of complications exhibited a statistically decreasing risk with each supplementary procedure that was performed (p = 0.0067) in the LP group, but not in the OP group (p = 0.9665).

Conclusion

From a learning process perspective, laparoscopy is mainly associated with a significantly higher risk of specific complications. This risk decreases in line with the surgeon’s level of experience, whereas non-specific complications remain stable in open procedures.

     

Airway reconstruction using decellularized tracheal allografts in a porcine model

Purpose

Tracheal cartilage reconstruction is an essential approach for the treatment of tracheal congenital abnormalities or injury. Here, we evaluated the use of allogeneic decellularized tracheas as novel support scaffolds.

Methods

Six weaned pigs (4-week-old domestic males) were transplanted with allogeneic tracheal graft patches (three decellularized and three fresh tracheal scaffolds) onto artificial defects (approximately 15 × 15 mm). After 11 weeks, the tracheas were evaluated by bronchoscopy and histological studies.

Results

No pigs displayed airway symptoms during the observation period. Tracheal lumen restored by fresh graft patches showed more advanced narrowing than that treated with decellularized grafts by bronchoscopy. Histologically, fresh grafts induced typical cellular rejection; this was decreased with decellularized grafts. In addition, immunohistochemistry demonstrated regenerating foci of recipient cartilage along the adjacent surface of decellularized tracheal grafts.

Conclusion

Decellularized allogeneic tracheal scaffolds could be effective materials for restoring impaired trachea.

     

Clinical safety of 3-T brain magnetic resonance imaging in newborns

Background

The effects and potential hazards of brain magnetic resonance imaging (MRI) at 3 T in newborns are debated.

Objective

Assess the impact of 3-T MRI in newborns on body temperature and physiological parameters.

Material and methods

Forty-nine newborns, born preterm and at term, underwent 3-T brain MRI at term-corrected age. Rectal and skin temperature, oxygen saturation and heart rate were recorded before, during and after the scan.

Results

A statistically significant increase in skin temperature of 0.6 °C was observed at the end of the MRI scan (P<0.01). There was no significant changes in rectal temperature, heart rate or oxygen saturation.

Conclusion

Core temperature, heart rate and oxygen saturation in newborns were not affected by 3-T brain MR scanning.

     

Chinese guidelines for the diagnosis and treatment of hand,foot and mouth disease (2018 edition)

Background

Hand, foot, and mouth disease (HFMD) is a common infectious disease in childhood caused by an enterovirus (EV), and which is principally seen in children under 5 years of age. To promote diagnostic awareness and effective treatments, to further standardize and strengthen the clinical management and to reduce the mortality of HFMD, the guidelines for diagnosis and treatment have been developed.

Methods

National Health Commission of China assembled an expert committee for a revision of the guidelines. The committee included 33 members who are specialized in diagnosis and treatment of HFMD.

Results

Early recognition of severe cases is utmost important in diagnosis and treatment of patients with HFMD. The key to diagnosis and treatment of severe cases lies in the timely and accurate recognition of stages 2 and 3 of HFMD, in order to stop progression to stage 4. Clinicians should particularly pay attention to those EV-A71 cases in children aged less than 3 years, and those with disease duration less than 3 days. The following indicators should alert the clinician of possible deterioration and impending critical disease: (1) persistent hyperthermia; (2) involvement of nervous system; (3) worsening respiratory rate and rhythm; (4) circulatory dysfunction; (5) elevated peripheral WBC count; (6) elevated blood glucose and (7) elevated blood lactic acid. For treatment, most mild cases can be treated as outpatients. Patients should be isolated to avoid cross-infection. Intense treatment modalities should be given for those severe cases.

Conclusion

The guidelines can provide systematic guidance on the diagnosis and management of HFMD.

     

Glypican-3 mRNA expression level in Wilms tumor: correlation with histological type,stage, and outcome

Purpose

To correlate expression of Glypican-3 in Wilms tumor with histopathology, stage, and outcome.

Methods

Glypican-3 mRNA expression by real-time PCR on tumor and normal germline samples from 75 fresh nephrectomies for Wilms tumor with fold change after normalization against GAPDH was compared. Survival analysis for event-free and overall survival (EFS, OS) with 2-year follow-up for Glypican-3 overexpression (>1.5 times) and clinicopathological parameters was performed.

Results

Glypican-3 was overexpressed in 37/75 (49.3%). It was overexpressed in 77% (10/13) cases with blastema predominance or anaplastic histology, as compared to 44% of other histologies (27/62) (p = 0.03). OS was 73 and 93%, respectively (p = 0.016), for those with and without GPC-3 overexpression. EFS was not significantly different with Glypican-3 overexpression (p = 0.11). All 5 deaths among blastema predominant tumors and 4/5 deaths among triphasic tumors had overexpressed Glypican-3. Most deaths in Stage IV, Stage III, and Stage I + II (5/7, 3/3, 1/1) had GPC-3 overexpression. On multivariate analysis, only histology and stage were found to have independent prognostic value.

Conclusion

Glypican-3 overexpression in Wilms tumor correlates with poor OS on univariate analysis. However, only histology and stage have independent prognostic value. Glypican-3 levels may help to stratify intermediate outcome histology (triphasic) and Stage III Wilms tumors.

     

Hämorrhagischer Schock im frühen Kindesalter – Besonderheiten der Kreislaufregulation

Background

Acute hemorrhages in neonates and young children can be compensated for a long period of time until a decrease in blood pressure and manifest shock occur.

Objective

To determine the characteristics of the pathophysiology of the circulation in children and to recognize critical signs and symptoms of hemorrhage.

Material and methods

Pathophysiology and discussion of the literature

Results

Shock in neonates and children can be present long before a decrease in blood pressure occurs. It is characterized by tachycardia, tachy(dys)pnea, prolonged capillary refilling time, disorders of consciousness (apathy), disturbance of temperature regulation and reduced urine output. Laboratory markers are metabolic acidosis and elevated lactate and a normocytic anemia earlier than in adults.

Conclusion

In contrast to adults a decrease in blood pressure in neonates and young children is a late sign of shock, whereas normocytic anemia occurs earlier than in adults.

     

Experience of diagnosis and treatment of 31 H-type tracheoesophageal fistula in a single clinical center

Objective

To summarize the experience of the diagnosis and treatment of 31 H-type tracheoesophageal fistula (TEF) at the Children’s Hospital of Chongqing Medical University, Chongqing, China.

Methods

A total of 31 patients with H-type TEF were enrolled in this retrospective study from January 2000 to July 2017, and the diagnosis and treatment of the disease were analyzed and summarized.

Results

Iodine oil examination of the esophagus, fiberoptic bronchoscopy combined with esophagoscopy and three-dimensional computed tomography (3-D CT) reconstruction of the trachea and esophagus was used separately in 31 patients. 1 patient who had his TEF ligatured directly experienced recurrence 1 month after surgery, but recovered after TEF suturing. Subsequently, the remaining 30 patients were treated by suturing after TEF excision. All patients were followed up for 3 months–2 years and did not suffer from anastomosis orifice stenosis, gastroesophageal reflux, and a recurrent respiratory tract infection. Three patients exhibited vocal cord paralysis and improved spontaneously after a follow-up of 3–6 months.

Conclusion

H-type TEF is diagnosed by iodine oil examination of the esophagus, fiberoptic bronchoscopy combined with esophagoscopy, and 3-D CT reconstruction of the trachea and esophagus. Excision and suturing of the TEF separately are an effective treatment for the disease and are an excellent outcome.

     

Short Term Oral Zinc Supplementation among Babies with Neonatal Sepsis for Reducing Mortality and Improving Outcome – A Double-Blind Randomized Controlled Trial

Objective

To evaluate the efficacy of short term zinc supplementation on the mortality rate and neurodevelopment outcome in neonates with sepsis at 12 mo corrected age.

Methods

The clinical trial was undertaken in the neonatal intensive care unit of JIPMER during the time period from September 2013 through December 2016. Neonates with clinical manifestations of sepsis who exhibited two positive screening tests (microESR, C- reactive protein, band cell count) were included and randomized into no zinc and zinc group. The intervention was zinc sulfate monohydrate given at a dose of 3 mg/kg twice a day orally for 10 d along with standard antibiotics. The no zinc group was on antibiotic treatment. Blood samples from both groups were collected at baseline and after day 10. Babies were carefully discharged from the hospital. The babies were followed up till 12 mo corrected age using DASII (Development Assessment Scale for Indian Infants).

Results

At the time of enrolment, patient characteristics were similar in both the groups. The mortality rate was significantly higher in no zinc compared to zinc group (5 vs. 13; P = 0.04). Although motor development quotient was similar, mental development quotient was significantly better among babies who received zinc supplementation.

Conclusions

Short term zinc supplementation of newborns with sepsis reduces mortality and improves mental development quotient at 12 mo of age.

     

Age Specific Peak Expiratory Flow Nomogram in Children

Objective

To determine peak flow rate nomogram in children between 5 to 12 y of age in suburban population.

Methods

This was a cross-sectional study randomly done on 5000 healthy school children. Mini-Wright flow meter was used for measurement of peak expiratory flow rate (PEFR). The range of age, weight and height were defined and linear and multiple regression analysis were performed.

Results

Correlation between PEFR and height was more significant and between PEFR and weight was lower. On the basis of height, the regression equation for both sexes were drawn; Boys: PEFR = 3.29 (Height in cm) - 218.38; Girls: PEFR = 3.25 (Height in cm) - 216.49.

Conclusions

Thus, region specific nomograms for PEFR for assessing the severity and monitoring of airway obstruction in relation to age, sex, weight and height of children can be determined.

     

Primary sigmoidectomy and appendicostomy for chronic idiopathic constipation

Purpose

To present our experience in patients with chronic idiopathic constipation complicated by megarectosigmoid and fecal incontinence who underwent a primary sigmoidectomy and appendicostomy.

Methods

We reviewed eight patients referred to the Colorectal Center from 2014 to 2016 with chronic idiopathic constipation and undergoing a sigmoidectomy and appendicostomy. We analyzed the previous medical treatment, indications for the surgical procedure, and outcomes.

Results

Age at operation was 5–19 years. Time with constipation was 4–15 years. All patients received multiple laxatives, mainly polyethylene glycol, and all had severe social problems. Four patients have autism. The indication for surgery was an unsuccessful laxative trial, refusal to continue with rectal enemas or both, and social fear of continued fecal incontinence. Post-operatively, all patients were having daily bowel movements without fecal accidents.

Conclusion

Selected patients with chronic idiopathic constipation complicated by megarectosigmoid and fecal incontinence can obtain great benefit from primary sigmoidectomy and appendicostomy.

     

Dose optimisation for intraoperative cone-beam flat-detector CT in paediatric spinal surgery

Background

During surgery for spinal deformities, accurate placement of pedicle screws may be guided by intraoperative cone-beam flat-detector CT.

Objective

The purpose of this study was to identify appropriate paediatric imaging protocols aiming to reduce the radiation dose in line with the ALARA principle.

Materials and methods

Using O-arm® (Medtronic, Inc.), three paediatric phantoms were employed to measure CTDI_w doses with default and lowered exposure settings. Images from 126 scans were evaluated by two spinal surgeons and scores were compared (Kappa statistics). Effective doses were calculated. The recommended new low-dose 3-D spine protocols were then used in 15 children.

Results

The lowest acceptable exposure as judged by image quality for intraoperative use was 70 kVp/40 mAs, 70 kVp/80 mAs and 80 kVp/40 mAs for the 1-, 5- and 12-year-old-equivalent phantoms respectively (kappa = 0,70). Optimised dose settings reduced CTDI_w doses 89–93%. The effective dose was 0.5 mSv (91–94,5% reduction). The optimised protocols were used clinically without problems.

Conclusions

Radiation doses for intraoperative 3-D CT using a cone-beam flat-detector scanner could be reduced at least 89% compared to manufacturer settings and still be used to safely navigate pedicle screws.

Maturation of pelvic ossification centers on computed tomography in normal children

Background

The pelvis is composed of three paired primary ossification centers: the pubis, the ischium and the ilium. During maturation, multiple secondary ossification centers can be seen in the synchondroses between these bones and in the pelvic apophyses. The fragmented appearance of these centers can be confused with pathology.

Objective

To examine development of pelvic ossification centers by CT and determine normal appearance throughout childhood.

Materials and methods

Three pediatric radiologists reviewed 325 pelvic CT scans in children and young adults 5–18 years old and graded 6 pelvic ossification centers to evaluate maturational changes in critical structures.

Results

Rate and progression of ossification and age at complete fusion vary with gender at the different ossification centers in the growing pelvis.

Conclusion

Knowledge of the normal CT appearance of ossification centers throughout childhood is important to differentiate the normal appearance from pathology.

     

Physical Activity Patterns Among School Children in India

Objective

To assess the prevalence of physical activity and its relation with socio-demographic variables and eating habits among school-aged children in India.

Methods

The study incorporated secondary analysis of anthropometric measurements and questionnaires on lifestyle and dietary habits of 1,680 school children aged between 3 and 11 y, obtained while carrying out the OBEY-AD project. The inventory contained questions about several variables concerning to physical activity, educational background, lifestyles and eating habits for both children and parents. Questions were organized along specific contents, which could be informative topics, picture choices and multiple answers choices.

Results

Prevalence of inactivity was 21 % and exhibited significant variations between cities. Physical activity was significantly associated to socio-economic status and consumption of fruits and vegetables. No association could be revealed with children’s BMI.

Conclusions

Health-promotion interventions aimed at improving healthy lifestyles in Indian children should focus on population strata with low socio-economic status.

     

Elevated serum neopterin levels in children with functional constipation: association with systemic proinflammatory cytokines

Background

Functional constipation is a clinical problem with an incompletely understood etiology. Functional bowel diseases have been shown to be related to inflammation in many studies in adults. In this study, we aimed to evaluate leukocytes, C-reactive protein, proinflammatory and anti-inflammatory cytokines, and neopterin levels in children with functional constipation.

Methods

Seventy-six children with constipation and 71 healthy controls (mean age 7.12 ± 3.46 years and 7.32 ± 4.33 years, respectively, P = 0.991) were included in the study. Leukocytes, C-reactive protein, interleukin (IL)-1β, IL-6, IL-10, IL-12, tumor necrosis factor-alpha (TNF-α) and neopterin levels were assessed in patients and healthy controls. Parameters were measured in the serum using enzyme-linked immunosorbent assay methods.

Results

Mean IL-6 (20.31 ± 12.05 vs. 16.2 ± 10.25 pg/mL, respectively, P = 0.003), IL-12 (181.42 ± 133.45 vs. 135.6 ± 83.67 pg/mL, respectively, P = 0.018) and neopterin levels (2.08 ± 1.12 vs. 1.52 ± 1.02 pg/mL, respectively, P = 0.001) were significantly higher in constipated children than healthy controls. Leukocyte and thrombocyte counts, C-reactive protein, and IL-1β, IL-10 and TNF-α levels did not show any difference between the two groups.

Conclusions

In this study, IL-6, IL-12 and neopterin levels of constipated patients were found to be higher than those of controls. These results indicate the presence of subclinical inflammation in children with functional constipation.
