Purpose: Association of spinal or vertebral anomalies and the iatrogenic denervation during surgical correction of anorectal malformation patients especially in boys can lead to neurogenic bladder inthese subset of patients. The paucity of literature with regard to urodynamic studies focusing exclusively in male children with high-anorectal malformations (HARM) lead us to analyze the urodynamic changes. The objective was to study urodynamic profile in male patients who have undergone surgery for anorectal malformation., Methods: Male high-anorectal malformation patients who had completed all the stages of repair were prospective studied. Following the basic work up, all patients based on the urodynamics were categorized into 2 groups as safe or unsafe bladders. Unsafe bladder was defined as detrusor pressure > 40 cm (high detrusor pressure) or pressure variability of 15 cm of water (detrusor overactivity) or significant post-void residue. MRI was limited to patients with only abnormal urodynamics to rule out spinal causes of neurogenic bladder and due to financial constraints, it could not be offered to all patients., Results: 41 HARM meet the exclusion criteria. All patients were asymptomatic with none having history of urinary tract infections. Ultrasound showed bladder wall thickening in 31.7% patients. UDS revealed reduction in bladder capacity and compliance was noted in 31.7% and 30% patients, respectively. Elevated detrusor pressures (> 40 cm of water) were noted in 10% (4/41), detrusor overactivity with concomitant elevated detrusor pressures in 19.5% (8/41) and normal UDS in 70% (29/41). 13 patients (31.7%) had abnormal cystometric parameters with 12(30%) having unsafe bladders. MRI confirmed sacral agenesis in 1 patient with unsafe bladder., Conclusion: Urodynamics can demonstrate occult neurovesical dysfunction in patients with HARM. This would help in early renal protective therapy and prevent the burden of long-term sequelae of neurovesical dysfunction in HARM patients.

Introduction: Neurogenic bladder (NB) post-meningomyelocele (MMC) repair is a major challenge and needs lifelong follow-up. Many cytokines have been implicated in the pathogenesis of NB. To avoid repeated urodynamic studies (UDS) and renal scans, we studied urinary tissue inhibitors of metalloproteinases-2 (TIMP-2) levels and correlated with urodynamic profiles to establish their efficacy., Materials and Methods: Prospective case-control study on children between 6 months to 12 years of age, who were at least 6 months post-MMC repair and had NB on UDS. Patients were evaluated under 4 cohorts of 20 patients each: Group A (NB on treatment), Group B (NB not on treatment), Group C (no NB), and Group D (Controls). All groups underwent radiofrequency thermocoagulation, urine culture, ultrasonography. Urine samples were stored at -800°C and analyzed using a validated Human ELISA kit for TIMP-2., Results: Eighty patients with a mean age of 3.54 ± 2.1 years were studied. A common ultrasound finding was a thickened urinary bladder (33.3%). All UDS parameters showed a statistically significant differences between groups with NB (Groups A and B) and a group without NB (Group C). Analysis of TIMP-2 levels between individual groups was statistically significant. The area under the receiver operating characteristic curve between urinary TIMP-2 and cystometric parameters indicated that urinary TIMP-2 levels are highly diagnostic of NB. TIMP-2 value of 358.5 pg/ml was found to be the least value with 93.5 sensitivity and 86.2% specificity., Conclusion: This study highlights the potential of urinary marker TIMP-2 as noninvasive and cost-effective test to initially diagnose and predict the progression of disease in NBs with reasonable sensitivity and specificity., (© 2020 Wiley Periodicals LLC.)

Purpose: This study is carried out to characterize the prognosis and outcome of antenatally diagnosed cystic hygroma in a series of registered pregnancies., Methods: This is a prospective cohort study, carried out over a period of 4 years (Jan 2016-Sept 2019). All the pregnancies referred from the department of obstetrics with antenatally detected cystic hygroma or increased nuchal thickness on level II ultrasonography suggestive of lymphangiomas were registered in the Pediatric Surgery outpatient department. Amniocentesis, fetal ECHO and fetal MRI (if indicated)were done. Prognosis was explained to the family and mode of delivery was planned as per the obstetric indications. Postnatal evaluation included general physical examination along with ultra sound (USG)doppler of the lesion. The neonates were admitted in neonatal surgical ICU for the administration of intralesional bleomycin in a dose of 0.3 IU/kg under strict observation. All the babies were followed up at 3, 6 and 12 months. Results were segregated as excellent, good and still in follow up cohort as per the final outcome. The fetal neck masses detected antenatally and the age at first dose of bleomycin were compared with the number of sclerotherapy doses required to achieve good response., Results: Only nine patients out of 626 registered pregnancies (1.4%) were diagnosed with cystic hygroma. One antenatal mother opted for termination of pregnancy at 19 weeks of gestation and another patient was lost to follow up after receiving two doses of bleomycin in postnatal period. Maternal hypothyroidism was noted in two pregnancies. Antenatal USG shows increased nuchal thickness in 2 cases (first trimester) and 6 cases in level II scan. Amniocentesis shows normal fetal karyotyping in all these pregnancies. Fetal ECHO suggests normal biventricular function in 100% cases while fetal MRI done in one case completely ruled out any aerodigestive compromise. Mode of delivery is found to be planned elective LSCS in 57% of cases while normal vaginal delivery attained in 43% of cases as per the obstetric guidelines. Six cases achieved good response with >50% reduction in size out of which 4 cases received the dose at the first 10 days of life. Complete disappearance of lesion at the end of 6 months of follow up were seen in two babies., Conclusions: Antenatal screening for early detection of fetal cystic hygroma with possible associated congenital aneuploidies helps in prognostication and planning the mode of delivery. A multimodality approach during intra and postpartum increases safety margin. Even huge neck masses without associated anomalies carry fair prognosis. Intralesional bleomycin is safe and prevents surgical morbidity., (Copyright © 2020. Published by Elsevier B.V.)

Aim: Vesicoscopic Cohen's reimplantation closely replicates the open procedure and is reported to have equally good results. Robotic assisted vesicoscopic reimplantation (RAVR) is a new procedure, and the information on technique of RAVR is sparse. We present our technique, experience, and early outcome with RAVR and review of literature. Patients and Methods: We retrospectively evaluated patients with vesicoureteric reflux grade II and above. These patients were subjected to RAVR. Selection criteria for this procedure were age >4 years, preserved renal function, and bladder capacity >250 mL. Patients with previous bladder surgery or urethral issues were excluded. Patients were operated by DaVinci Si system, and the technique is described in detail. Three ports were placed by use of bougie. The ureters were adequately mobilized before placing in submucosal tunnel. Results: Total of 5 ureters were reimplanted in 4 patients (2 females and 1 bilateral). Ureteral tapering was done in 1 patient. Mean port placement time was 25 minutes with 12 minutes of docking time. Mean console time was 70 minutes for unilateral cases and 100 minutes for the bilateral case. There was resolution of reflux in all patients. The mean follow-up duration is 9 months. Conclusions: Robotic assisted vesicoscopic reimplantation is a feasible and safe method of replicating Cohen's reimplantation. There is a learning curve with the procedure, and nuances related to the technique need to be learned by the surgeon. This is the third report on RAVR and provides the necessary technical details required by a robotic surgeon to replicate this procedure.

Background: We wish to describe a novel technique of transdiaphragmatic excision of hepatic hydatid in patients with synchronous ipsilateral lung hydatid. Patients and Methods: Two patients, aged 11 and 6 years, presented with large synchronous hydatid cyst in right lung and liver. Second patient had two large cysts in right lobe of liver in posterior-superior segment of VII and VIII. The patients underwent thoracoscopic excision of lung cyst, and in same sitting the liver hydatid was seen bulging through the diaphragm. The diaphragm was incised to expose the cyst beneath, with excision of hydatid. Port-in-cyst technique was used to excise the membranes. Results: Both lung and liver cyst were successfully removed through thoracoscopic approach and a laparotomy was altogether avoided. Both patients did well in follow-up (3 years and 6 months). There are no respiratory issues in these patients. Conclusions: This is a novel approach for multiple synchronous hepatic and pulmonary hydatid. This can be applied in specific scenario as described. It gives a significant advantage of avoiding a laparotomy and thoracotomy in patients and thus reducing morbidity.

Context: Anterior sagittal anorectoplasty (ASARP) is accepted as one of the techniques for the repair of vestibular fistula (VF) and low-type anomalies, but some may have reservations., Aims: The aim of the study is to describe the technique, important features, and functional and cosmetic outcomes of ASARP for the treatment of anorectal malformation (ARM) in females., Settings and Design: A prospective study was performed from 1992 to 2017., Materials and Methods: The study included 157 pediatric patients (aged 1-15 years) with diagnosis of ARMs with VF, perineal fistula (perineal ectopic anus), and rectovaginal fistula managed by ASARP., Results: Most cases (36.94%) were 1-6 months' age group; 92.99% of patients (146) were having VF, 5.09% (8) perineal fistula, and 1.91% (3) rectovaginal fistula. Associated anomalies (37) were present in 19.75% (31) of patients. Primary ASARP was performed in 85.35% (134) of cases. The mean operative time was 105 (±15) min. Intraoperative complications were seen in 3.82% (6) of patients. Early postoperative complications were seen in 5.09% (8) of patients - wound infection (4), wound dehiscence (3), and retraction of the rectum (1). Late complications were seen in 12.73% (20) of cases. Overall, five patients developed anal stenosis, two responded to dilatation therapy, and three required anoplasty. The external appearance of the perineum after the 3 rd month (postoperatively) was satisfactory in 95.54% (150); overall, 4.46% (7) of patients required the second procedure. Stooling pattern could be assessed in 80.25% (126) of patients at 3 years' age group. Only one had poor outcome with severe soiling (incontinence) and perineal excoriation that also had myelomeningocele., Conclusions: ASARP is an excellent procedure for VF as it results in optimal correction with minimal sphincteric damage, without additional complexity or difficulties. Primary ASARP is a quick and effective technique and does not require colostomy if performed after due preoperative gut preparation and by an experienced pediatric surgeon., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Journal of Indian Association of Pediatric Surgeons.)

Aim: The aim is to prospectively study 125 trauma patients admitted in the pediatric surgery ward in our institute., Materials and Methods: Pediatric patients admitted in the ward after initial resuscitation in the triage room were included. Isolated neurosurgical and orthopedic injuries were excluded. X-ray cervical spine, hip, and chest and a focused assessment with sonography in trauma ultrasound were done for all patients. Computed tomography of the abdomen or chest was done where relevant. Injury profile and surgical intervention when needed were analyzed., Results: Road traffic accidents and fall from height caused 73.6% of the injuries. School-going children were most commonly affected (60.8%). Distinctive injuries were noted such as abdominal wall hernias and delayed bladder perforation. All solid organ injury irrespective of grade treated conservatively. Forty percent of the children required surgical intervention. Five patients after laparotomy were found to have surgical conditions unrelated to trauma, whereas another 14 required delayed surgery. Five patients had injuries secondary to sexual abuse. All except two patients were discharged in a satisfactory condition and are doing well in the follow-up., Conclusion: In spite of extensive injuries and the need for multiple surgeries, children with trauma have a good prognosis. Close observation during admission and also in follow-up are essential, as many patients may require delayed surgery ≥1 week from injury., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Journal of Indian Association of Pediatric Surgeons.)

The house crickets, Acheta domesticus, are sustainable and nutritious future sources of food, due to their nutritional benefits, particular high protein content and potential in solving global malnutrition. Different diets, particularly protein content, can influence the growth and nutritional value of crickets. The aim of this present study was to evaluate the effects of commercial diets and other formulated diets on the nutritional composition and growth parameters of the house crickets, being a major challenge to cricket's farmers in Thailand. Feed conversion ratio were 1.50, 1.50, and 1.51 for fed crickets on a blend of 22% protein and dry pulp pumpkin powder, fed 22% protein plus fresh pumpkin pulp, and fed 22% protein alone, indicated that these groups are high feed convertors and represented the quality of these diets compared to 1.73 and 1.81 for fed crickets on a blend of 22% and 16% protein, and those fed on 16% protein alone. Fed crickets on 22% protein had the highest amount of protein (76%), the lowest (48%) in those fed on 22% protein and fresh pumpkin pulp inclusion. The group on 22% protein diet also had the highest amount of phosphorus, potassium, calcium, and sodium. Fed 22% protein and either dry pulp pumpkin powder or fresh pumpkin pulp condition have shown improvement in vitamin B content. Crickets can effectively be produced on 22% protein diet to improve yield output and several minerals such as phosphorus, potassium, calcium, and sodium. In contrast, the supplementation of 22% protein diet with pumpkin (Cucurbita maxima) will improve vitamin B content., (© The Author(s) 2020.

A novel route was created to facilitate the degradation of diethyl phthalate (DEP) upon micellar polyoxometalate (POM) catalysts and H 2 O 2 . The best catalytic activity was obtained using [C 16 H 33 N(CH 3 ) 3 ]H 4 PMo 10 V 2 O 40 (N-hexadecyl-N,N,N-trimethylammonium tetrahydrogen decamolybdo-divanadophosphate, abbreviated as (CTA)H 4 PMoV) with 90.2% degradation efficiency within 30 min, while the chemical oxygen demand (COD) and total organic carbon (TOC) removal efficiency were about 77.7% and 74.3% within 40 min. The highest efficiency was attributed to the concentration of DEP by amphiphilic POM catalyst, coupling with its strong Brønsted acidity and higher redox potential to catalyze esterolysis and oxidation of DEP. This allowed the phthalate acid esters (PAEs) with long carbon chains in super low concentration of 0.03 μM to be efficiently decomposed. The above synergistic effects explored DEP being degraded into ethanol, lactic acid and CO 2 , which were non-toxic to the water surroundings. And the reaction activation energy (Ea) of 12.49 kJ/mol was obtained upon the degradation of DEP with (CTA)H 4 PMoV followed first-order kinetics. Meanwhile, (CTA)H 4 PMoV acted as a heterogeneous catalyst, which showed long duration and higher stability with only 3.7% loss amount during ten recycles., (Copyright © 2019 Elsevier B.V.

Background: Placement of ventriculoperitoneal shunt is a standard treatment for hydrocephalus. The risk of shunt malfunction in the first year is 25%-40% making endoscopic third ventriculostomy (ETV) a feasible option in those patients with shunt failure., Aim: The aim of this study was to evaluate ETV as a viable option in patients with shunt malfunction and to correlate the clinical outcome following successful ETV with functional and radiological outcomes., Materials and Methods: All patients who underwent ETV as a diversion procedure for hydrocephalus following shunt failure or malfunction over 1 year were studied. Functional outcome was evaluated by Wee function independence measure score carried out preoperatively, postoperatively, and at 6-month follow-up. Similar comparison was carried out for radiological parameters such as effacement of gyri, periventricular lucency, frontal horn diameter (maximum), Evans' index, and third ventricular diameter., Results: Of 15 patients, 61.5% were shunt free after ETV. All the failures were noted in the first month following the procedure. The factors, which showed statistically significant correlation with the outcome of ETV, included age ( P = 0.030), preoperative functional score ( P = 0.006), and all the three components of the functional scoring, namely self-care score ( P = 0.087), motor control score ( P = 0.035), and neurocognitive score ( P = 0.003). Parameters such as Evans' index, maximum frontal horn diameter, and third ventricular diameter showed no significant difference between preoperative and postoperative scans. In follow-up imaging, only the frontal horn diameter showed a significant improvement ( P = 0.047)., Conclusion: ETV leads to significant neurocognitive improvement and postoperative functional status making it a viable option in patients who present with shunt malfunction., Competing Interests: There are no conflicts of interest.

Introduction: Ventriculoperitoneal (VP) shunt is a commonly performed neurosurgical procedure in pediatric surgical practice. This study is aimed at determining the outcome of congenital hydrocephalus patients who underwent shunt surgery at our center., Materials and Methods: A total of 278 operated cases of congenital hydrocephalus with a minimum follow-up of 6 months were analyzed in terms of complications. Hydrocephalus associated with intracranial hemorrhage, neural tube defects, and ventriculitis were excluded from the study., Results: Complications were observed in 32.0% (89/278) of cases. Shunt block and chamber migration were the most common complications (29.21%). Abdominal wound complications were seen in 4.49% of cases. Shunt exposure due to erosion of overlying skin was noted in 6 patients. Shunt infection was diagnosed in only 9 patients (4.4%). New-onset seizures were seen in 4 cases. Overall, 21% of patients required redo shunt and there were 2 mortalities., Conclusion: VP shunt continues to have high complication rates. Shunt migration and new-onset seizure disorders are important late complications. In spite of inherent problems, shunt surgery is the procedure of choice until a safer effective alternative is available., (© 2019 S. Karger AG, Basel.)

Objective: To report our experience with endoscopic management of vesicoureteral reflux (VUR) by injection of a tissue bulking substance - Dextranomer/ hyaluronic acid co-polymer at vesicoureteric junction., Design: Retrospective analyses of case records., Setting: Pediatric Surgery department in a tertiary care government Institute., Participants: 500 children (767 renal units) consecutively referred to the out-patient department with vesicoureteral reflux noted on micturating cysto-urethrogram (MCU) over a period of 13 years (2004-2016)., Intervention: Preoperative VUR grading and renal scars on radionuclide scans were documented. Dextranomer hyaluronic acid copolymer was injected through a cystoscope at the vesicoureteral junction as a day care procedure under short anesthesia. Patients were followed (average duration 27.3 mo) with clinical assessment, periodic urine cultures and renal scans., Main Outcome Measure: Cessation of VUR and symptomatic relief / clinical success postoperatively at 3 months., Results: Complete symptomatic relief was obtained in 482 (96.4%) patients. In 681 units where MCU was available, 614 (90%) units showed resolution of VUR., Conclusions: Endoscopic injection of tissue bulking substances at vesicoureteric junction to stop VUR seems to be an effective intervention.

The occurrence of multiple neural tube defects in a single patient is rare; the cases reported in the past are mostly of thoracic and lumbosacral region. Double occipital encephaloceles are rare; only four cases have been reported till date. Here we report a case of double encephalocele-one in the vertex and the other in the occiput, and a literature study on similar reports., Competing Interests: There are no conflicts of interest.

Aim: Airway foreign body (FB) is a very common pediatric surgical emergency. On certain difficult occasions, the extraction of FB with optical forceps (OFs) is difficult. These conditions create a life-threatening scenario. We present some of the alternative methods of FB extraction for these situations., Patients and Methods: This is a retrospective case review of patients presenting to pediatric emergency with airway FB. All patients had a chest X-ray done before the procedure. Rigid bronchoscopy was performed in all patients for retrieval., Results: A total of 20 patients (6 females) were successfully scoped. The age ranged from 1.5 years to 12 years (mean 3.5 years). Bronchoscopic removal was aided by dormia basket (DB) in 13, Fogarty's catheter (FC) in 6, and magnet aided removal in 1. Complete removal was achieved in all patients., Conclusions: We recommend that DB, FC, and a magnet should form an indispensable part of bronchoscopy set. The use of these alternative methods is successful and allows ventilation during the removal in contrast to removal by OFs. These should be kept as an option if retrieval is difficult., Competing Interests: There are no conflicts of interest.

We report an unusual presentation of annular pancreas with pneumoperitoneum in a newborn with an associated left sided Erb's palsy. The neurological deficit caused considerable confusion in the diagnosis and unexpected complications after surgery. We highlight the importance of clinical examination and the complications that an Erb's palsy can cause. This unusual triad of Erb's palsy, eventration of diaphragm and annular pancreas has hitherto not been described in literature.

Congenital pouch colon (CPC) is frequently associated with vesicoureteric reflux (VUR). These patients require long-term antibiotic prophylaxis and/or an additional surgical intervention for the management of the refluxing system. We propose a single-stage alternative approach in these patients. Two patients diagnosed to have CPC underwent pouch excision and an end colostomy at birth. Further evaluation revealed high-grade reflux in both the patients. At 6 months of age, definitive abdominoperineal pull-through (APPT) surgery along with extravesical detrusorrhaphy was performed. In the follow-up at 1 year, they are thriving well with no urinary complaints. Micturating cystourethrogram revealed complete resolution of VUR. This approach takes the advantage of the anesthesia for APPT and offers a relatively simple and quick solution for the refluxing system, thus, enabling the stoppage of antibiotic prophylaxis and obviating the need for a future endoscopy/surgery., Competing Interests: There are no conflicts of interest.

Background: Spina bifida is a common cause of pediatric neurogenic bladder. It causes renal failure in almost 100% of patients if the associated detrusor sphincter dyssynergia (DSD) is inadequately managed. Detrusor instability and high detrusor pressures (Figure) have been implicated as the major factors predictive of renal damage in these patients. Urodynamic studies provide early identification of "at risk" kidneys so that appropriate intervention can be made. However, the role in post-operative patients of spina bifida who have no clinical manifestations remains unclear., Objective: To study the bladder dynamics in asymptomatic post-operative patients of spina bifida and to determine whether routine urodynamic study is justifiable., Material and Methods: Urodynamics was performed on 15 operated patients of spina bifida who did not have any neurological deficit and were asymptomatic., Results: The mean age of the patients was 4.97 years. None of the patients had any urological complaints with their ultrasonography being normal. None had scars on nuclear scan. Of the 15 patients, 12 (80%) had abnormal findings on urodynamic assessment. Three patients (20%) had detrusor pressures greater than 40 cm of H 2 O. One patient had significant residual urine and detrusor instability., Discussion: The use of urodynamic studies in asymptomatic patients of spina bifida remains controversial, with one school of thought advocating early invasive urodynamic testing. In contrast, some favor noninvasive sonological monitoring, reserving invasive tests only for patients with renal tract dilatation. In our subset of patients none had renal tract dilatation but three patients (20%) had "at risk" bladders. These patients would benefit from early intervention aimed at renal preservation. The study is limited by a small sample size because of the relative rarity of the patient profile included. A further multicenter study with a case-control design could conclusively indicate the role of urodynamic testing in these patients., Conclusion: Patients of spina bifida, even when asymptomatic, have a high incidence of unsafe bladders. Early identification and appropriate measures can protect kidneys from long-term damage, hence urodynamic profiling is mandatory for identification of potentially high-risk bladders., (Copyright © 2017 Journal of Pediatric Urology Company.

Scrotal migration of peritoneal end of ventriculo-peritoneal (VP) shunt into the patent processus vaginalis (PPV) is a rare complication. Its exact incidence is not mentioned in the literature till date. This may be because of the rarity of this complication, and also because all previous articles related to the complication were case reports. We, in our series, had an incidence of 0.9%. This prospective study has been conducted on 437 patients in the age group of 1 month-3 years who underwent VP shunt for hydrocephalus over a period of 5 years from 2007 to 2011. The incidence of a hernia manifesting after shunt insertion has been reported to be around 16.8%. The average age of patients at the time of insertion of the shunt was 27.25 months (3-48 months). All our patients presented with swollen right sided scrotum after an average of 4 months (3-5 months) after shunt insertion. Shunt migration was more common on the right which is consistent with the incidence of hernias in children. The proper management of such cases includes repositioning of the catheter with the proper closure of the PPV. Usually, shunt revision is not required. We discuss the etiology, treatment and preventive measures of this rare entity., Competing Interests: There are no conflicts of interest.

Alimentary tract duplication cysts are rare congenital anomalies, most commonly located in the ileum, but may present anywhere from mouth to anus.Clinically, they may be asymptomatic, incidentally diagnosed or may present with obstruction, volvulus, intussusception or gastrointestinal bleed. Here we report a case of a one year old male child presenting in gasping state and shock. Despite the initial strong suspicion of Meckel's diverticulum and tubercular abdomen, the final diagnosis remained elusive till exploratory laparotomy was performed which revealed a duplication cyst of ileum with perforation into the umbilicus. Duplication cyst should always be kept as a differential diagnosis so that early intervention can help in better management.

Purpose: To analyze quality of life of children operated for congenital hydrocephalus and the concern of parents in taking care of these children., Methods: Thirty patients who underwent ventriculo-peritoneal shunt were randomly selected with minimum gap of 1 year between surgery and study. Canadian validated questionnaire was used. Overall health score (OHS) and parental concern score (PCS) were correlated with gender, family type and number of surgeries., Results: Mean OHS was 159.43 which was summation of physical health (mean 45.76), social-emotional (mean 80.03) and cognitive health scores (mean 33.66). Mean OHS was 151.57 for males and 177.77 for females (p-value 0.233). Nuclear and joint families had mean OHS of 160.36 and 158.89 respectively (p-value 0.944). Those who underwent one surgery had mean OHS of 167.48 and PCS of 23.10 whereas mean OHS was 140.66 and PCS was 27.78 for those with multiple procedures. Mean PCS for males was 26.71 and for females was 19.33 (p-value 0.036 statistically significant). This was not statistically significant between nuclear (24.73) and joint families (24.26)., Conclusions: Quality of life of survivors of hydrocephalus is reasonably good even in developing countries due to keen parental involvement irrespective of gender, family type and number of surgeries., Competing Interests: There are no conflicts of interest.

Background: High and intermediate types of anorectal malformations (ARMs) in male neonates may be managed either by primary neonatal reconstruction without colostomy cover or by traditional policy of staged reconstruction after neonatal colostomy. Posterior sagittal anorectoplasty (PSARP) is the current widely practiced reconstructive technique with varied results., Aim: To assess our functional results of PSARP without colostomy in male neonates with high and intermediate ARMs compared to 3-stage (neonatal colostomy - PSARP - colostomy closure) methodology in a high volume tertiary care institution of a developing country., Patients and Methods: The number of colostomies performed for male high/intermediate anomalies and the number of babies who completed 3-stage reconstruction during a 10-year period is analyzed. The outcome of primary neonatal PSARPs during the same period was analyzed. Eighty primary PSARPs were compared to 81 staged reconstructions for outcome analysis, using Kelly score., Results: A total of 453 colostomies were performed, but only 253 of them completed all stages of reconstruction (52%). Good continence was achieved in 45% of cases of primary PSARP versus 26% in 3-staged surgery., Conclusions: Primary PSARP in neonatal period without colostomy is a good option for high and intermediate ARMs in males if the treating surgeon is reasonably skilled in neonatal surgery and PSARP procedures., Competing Interests: There are no conflicts of interest.

Background: Anticholinergics are well established in the management of neurogenic bladders. However, some patients do have sub-optimal response or severe side effects. This study is designed to assess and compare efficacy of gabapentin with oxybutynin in neurogenic bladders after surgery for spina bifida., Methods: Patients were randomized into three groups after urodynamic studies and started on oxybutynin, gabapentin, and combination of both, respectively. Thorough clinical and urodynamic reassessment was done at 6months and one year after starting treatment., Results: Forty-four patients (3-19years) were studied. Improvement was noted in symptoms as well as urodynamic parameters in all groups. Maximal improvement of symptom score was with combination of drugs at 1year. In urodynamic studies, compliance, pressures, and capacity showed improvement, which was significant between the groups at both six months and 1year for bladder pressures and volume. Improvement in compliance though marked was not statistically significant. Best response was seen in group receiving both drugs. Gabapentin was better tolerated than oxybutynin., Conclusion: Gabapentin is a good alternative to oxybutynin for management of neurogenic bladder, both as monotherapy and as an add-on therapy. It has potential application in patients with inadequate response to anticholinergics., Level of Evidence: prospective competitive treatment study - level II., (Copyright © 2016 Elsevier Inc.

Aims: To investigate the role of feeding jejunostomy (FJ) in patients of esophageal atresia with anastomotic leak (AL) to decrease the degree of gastroesophageal reflux (GER) and its effect on anastomotic healing., Materials and Methods: Twenty neonates, with major AL and severe GER after primary repair were managed with decompressing gastrostomy and transgastric FJ and analyzed prospectively., Results: Male to female ratio was 1.7:1. Mean birth weight was 2.2 kg. Anastomotic gap ranged from 0 to 4 cm. The amount of leak was more than 20% of nasogastric feeds. Gastrostomy and FJ was done on an average of the 12(th) postoperative day, after observing the general condition, chest tube output, lung expansion, and ventilatory requirement. There was a drastic reduction in chest tube output and lung expanded in all patients. Average hospital stay was 36 days (8-80 days). Sixty percentage patients were discharged successfully on FJ. Esophagogram demonstrated healing and leak free patency after an average of 1.5 months. GER was noted in seven patients, four developed stricture, and one had pseudodiverticulum in follow-up., Conclusion: Decompressing gastrostomy and FJ can be an alternative to managing major ALs. It helps in healing of anastomotic dehiscence and in preserving the native esophagus.

Aims: The treatment of perforating esophageal foreign body impaction (FBI) is complex and unclear. We present the outcome of surgical treatment of esophageal perforations due to FBI in children along with a management algorithm., Methods: During a period of 7 years, 7 cases of esophageal perforations due to foreign body (FB) ingestion were referred to our unit. We analyzed the FB types, lodging duration and location, complications, and the surgical approaches., Results: There were 4 male and 3 female patients. Mean age was 28 months (5 months-6 years). Six patients had metal FBs of variable shapes and 1 had glass marble. Three patients had witnessed history of FB ingestion. Duration of ingestion was variable and unknown in half of the patients. The site of impaction was cervical (1) and thoracic (5) esophagus. One patient had a marble as FB in the superior mediastinum. One patient manifested with features of perforation after removal of the impacted FB and 5 patients presented with perforations. Two patients presented with subcutaneous emphysema. One patient had trachea-esophageal fistula (TEF) after disc battery ingestion. Rigid esophagoscopy failed in 4 out of 6 patients. Five patients underwent thoracotomy, and repair with a pleural patch reinforcement. One patient had lateral esophagotomy in the cervical esophagus for removal of the impacted FB. Mediastinal FB was removed without opening the esophagus. All the patients were discharged uneventfully., Conclusions: Esophageal perforation following FBI is rare and requires prompt treatment. Surgical treatment tailored to the needs of individual patients is associated with a successful outcome and decreased morbidity., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Study Design: Retrospective comparative study., Purpose: To assess differences in computed tomography (CT) imaging parameters between patients with cervical myelopathy and controls., Overview of Literature: There is a lack of information regarding the best predictor of symptomatic stenosis based on osseous canal dimensions. We postulate that smaller osseous canal dimensions increase the risk of symptomatic central stenosis., Methods: CT images and medical records of patients with cervical myelopathy (19 patients, 8 males; average age, 64.4±13.4 years) and controls (18 patients, 14 males; average age, 60.4±11.0 years) were collected. A new measure called the laminar roof pitch angle (=angle between the lamina) was conducted along with linear measures, ratios and surrogates of canal perimeter and area at each level C2-C7 (222 levels). Receiver-operator curves were used to assess the diagnostic value of each. Rater reliability was assessed for the measures., Results: The medial-lateral (ML) diameter (at mid-pedicle level) and calculated canal area (=anterior-posterior.×ML diameters) were the most accurate and highly reliable. ML diameter below 23.5 mm and calculated canal area below 300 mm(2) generated 82% to 84% sensitivity and 67% to 68% sensitivity. No significant correlations were identified between age, height, weight, body mass in dex and gender for each of the CT measures., Conclusions: CT measures including ML dimensions were most predictive. This study is the first to identify an important role for the ML dimension in cases of slowly progressive compressive myelopathy. A ML reserve may be protective when the canal is progressively compromised in the anterior-posterior dimension.

The appropriate pain management in neonates and children is lacking. Factors that prevent the execution of proper pain relief vary from center to center. We studied the factors responsible for it in a surgical unit. We conducted a survey at a tertiary-level institute among the resident doctors and nursing staff by means of an informal questionnaire analyzing their basic knowledge. The questions pertained mainly to pain assessment, analgesic usage, role of opioids, and formal training, and the responses so obtained were analyzed under these four headings. Seventy-three percent (22/30) of the residents and 74% (26/35) of the nursing staff knew about pain assessment scoring system in pediatric patients. However, assessment of pain in emergency cases was always done by only 6.6% of the residents. Effect of analgesia on severity of pain was never recorded by 33% (10/30) of the residents. Eighty-six percent (26/30) of the residents and 91% (32/35) of the nursing staff had adequate knowledge about analgesic dosage and interval for routine use. Ten of the 30 (33%) residents believed that analgesic administration in an acute abdomen, before definitive diagnosis, will always mask the symptoms. During a minor procedure, 56% (17/30) of the residents always used analgesia. Only 3.3% (1/30) of residents and 2.8% (1/35) of the nursing staff had received a structured training for pain management. Although, 93% (28/30) of the residents claimed to know about the safety of use of opioids, only 46% (14/30) used them routinely as analgesics. Pain management in surgical neonates and children is often ignored. Lack of formal training, inadequate knowledge, and standard protocols are the barriers in our setup, which may in turn be due to overwhelming attention given to the surgical condition.

Objective: To report the results of recto sigmoid bladder reservoir (RSBR), a variant of ureterosigmoidostomy (US) in patients with bladder exstrophy (BE) using a three dimensional evaluation system., Patients and Methods: This was a predominantly retrospective evaluation for all patients of BE undergoing RSBR who had completed minimum of 1 year follow-up. The patients were evaluated using a three dimensional system which included evaluation of urinary continence per rectally, status of upper tracts and health related quality of life (HRQOL)., Results: A total of 19 patients (four females) were evaluated. Mean age was 8.4 years, and mean duration of follow-up was 3.4 years. Mean age at RSBR was 5.1 years. Ten patients had good rectal continence. There was occasional minimal urine leak while passing flatus or on straining in nine. All patients had preserved renal function except one. The mean HRQOL score was 129.7 out of maximum of 150.., Conclusions: RSBR gives marked improvement in quality of life in patients of BE. In the literature there is a non-uniformity in the results reporting outcome of US. The presented three dimensional assessment provides a comprehensive way to report the results in the short/long term. If used by other surgeons it would make comparison across centers feasible., (Copyright © 2014 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.)

Background and Aims: In an attempt to further investigate the role of cannabinoid (CB) system in the pathogenesis of inflammatory bowel diseases, we employed two recently developed ligands, AM841 (a covalently acting CB agonist) and CB13 (a peripherally-restricted CB agonist) to establish whether central and peripheral CB sites are involved in the anti-inflammatory action in the intestine., Methods and Results: AM841 (0.01, 0.1 and 1 mg/kg, i.p.) significantly decreased inflammation scores in dextran sulfate sodium (DSS)- and 2,4,6-trinitrobenzene sulfonic acid (TNBS)-treated mice when administered before induction of colitis or as a treatment of existing intestinal inflammation. The effect was absent in CB1, CB2 and CB(1/2)-deficient mice. A peripherally-restricted agonist CB13 did not alleviate colitis when given i.p. (0.1 mg/kg), but significantly decreased inflammation score after central administration (0.1 µg/animal)., Conclusions: This is the first evidence that central and peripheral CB receptors are responsible for the protective and therapeutic action of cannabinoids in mouse models of colitis. Our observations provide new insight to CB pharmacology and validate the use of novel ligands AM841 and CB13 as potent tools in CB-related research.

Design: Retrospective case study., Objective: Percutaneous pedicle screw (PPS) techniques do not allow direct visualization and may lead to erroneous screw placement. A technique utilizing only fluoroscopy is described. Verification of its accuracy and morphometric validation are presented., Background: Minimally invasive spine surgical techniques, particularly PPS placement, have been growing in popularity. The purported benefits of minimally invasive spine surgical stated may be even more advantageous in the trauma setting., Methods: Jamshidi needles were docked in the typical starting position verified with posterior-anterior image. Jamshidi needle (20 mm) was advanced ensuring that the tip remained lateral to the medial pedicle wall. A Kirschner (K-wire) was placed through the needle. Once all the K-wires were placed, a lateral image was taken confirming the correct trajectory and that the wire passed the posterior vertebral body wall. Patients with PPS fixation were retrospectively studied with postoperative computed tomography to verify screw accuracy. Screw grade was assessed as grade I when completely within the pedicle, II <2 mm, III 2-4 mm, and IV >4 mm outside the pedicle. Morphometrically, 40 thoracic and lumbar computed tomography scans of patients (<40 y) without spine fractures were reviewed. The pedicle length was defined as the distance from the dorsal cortical margin to the posterior vertebral body in the pedicle's midaxis., Results: A total of 172 screws were placed. Eighteen percent were found to have cortical breach, but only 2.9% were found to have >grade II breach. The morphometric study demonstrated the pedicle length to range from 14.4 to 22.1 mm. The shortest was in the upper thoracic and the longest at L1-L2., Conclusions: The morphometric study demonstrates if a K-wire is placed 20 mm into the bone and remains lateral to the medial pedicle wall and the tip just engages the vertebral body, the screw trajectory is safe particularly in the lower thoracic and upper lumbar spine. A smaller distance may be utilized in the upper thoracic. Breach rates are similar to other reports using other techniques; none were clinically significant. The advantage of this technique is the use of only PA fluoroscopy for placing all the wires percutaneously.

Background: Predicting the outcome of congenital hydrocephalus in early infancy and childhood is difficult. Various consequences of hydrocephalus like ophthalmic, audiometric, musculoskeletal, and the developmental abnormalities play a complex role. We analyzed the quality of life of these patients in early life., Methods: A prospective multispecialty assessment of the patients with congenital hydrocephalus, who had undergone ventriculoperitoneal shunt in the Pediatric Surgery unit of a tertiary care hospital, was carried out and analyzed., Results: There were 24 boys and 6 girls. Eighty-three percent were operated before the age of 3 months. Mean age at follow up was 6 years (3-9 years). Shunt complications were seen in 53% (16) of the patients, out of which 68.75% had shunt blocks. In 70% (21) of the patients, the ventricle to hemisphere ratio (VHR) was between 51 and 70%, 20% (6) had a VHR of more than 70% and only 3 patients had a VHR between 40-50%. Audiological and ophthalmic problems were seen in 20 and 66% of the children, respectively. Musculoskeletal abnormalities were present in 36% of the patients. Developmental profile showed 44% being normal, 30% retarded, and 26% were borderline cases. The schooling had started in 56.6%, out of which only one child went to a special school., Conclusions: A multitude of problems associated with congenital hydrocephalus should be diligently diagnosed, aggressively followed and intervened with in the early years of life. Preschool management well before the peer interaction should optimize the social integration and improve the quality of life in these patients.

Purpose: The morbidity and mortality associated with esophageal atresia with or without a fistula make it a challenging congenital abnormality for the pediatric surgeon. Anatomic factors like inter-pouch gap and origin of fistula are not taken into consideration in various prognostic classifications. The preoperative evaluation of these cases with computerized tomography (CT) has been used by various investigators to delineate these factors. We reviewed these studies to evaluate the usefulness of this investigation in the intra operative and post operative period., Materials and Methods: A literature search was done on all peer-reviewed articles published on preoperative computed tomography (CT) in cases of tracheoesophageal fistula using the PUBMED and MEDLINE search engines. Key words included tracheoesophageal fistula, computerized tomography, virtual bronchoscopy, and 3D computerized tomography reconstruction. Further, additional articles were selected from the list of references obtained from the retrieved publications. A total of 8 articles were selected for analysis., Results: In most of the studies, comprising 96 patients, observations noted in preoperative CT were confirmed during surgery. In a study by Mahalik et al [Mahalik SK, Sodhi KS, Narasimhan KL, Rao KL. Role of preoperative 3D CT reconstruction for evaluation of patients with esophageal atresia and tracheoesophageal fistula. Pediatr Surg Int. 2012 Jun 22. [Epub ahead of print]], in 6 patients the fistula could not be identified pre-operatively by CT. One study found a difference of 0.43 cm in the intraoperative gap length compared to that given by CT when compared to +/- 2 mm shown by another [1. Mahalik SK, Sodhi KS, Narasimhan KL, Rao KL. Role of preoperative 3D CT reconstruction for evaluation of patients with esophageal atresia and tracheoesophageal fistula. Pediatr Surg Int. 2012 Jun 22. [Epub ahead of print], 3. Ratan SK, Varshney A, Mullick S, Saxena NC, Kakkar S, Sodhi PK. Evaluation of neonates with esophageal atresia using chest CT scan. Pediatr Surg Int. 2004 Oct; 20(10):757-61.]. Only three studies showed surgical utility of pre-operative CT, and the surgical plan changed based on the CT findings., Conclusion: The usefulness of pre-operative computerized tomography in cases of tracheoesophageal fistula is controversial. The safety of this technique is questionable due to limited facilities and associated radiation hazards. Further, limited information obtained which may help in changing the surgical plan can easily be managed intra-operatively by careful and meticulous surgery. Overall, the safety concerns outweigh its efficacy. Thus, the use of pre-operative CT scan cannot be generalized and protocolized as a standard of care in the management of tracheoesophageal atresia., (© 2013.)

Inflammasomes are large multiprotein complexes that have the ability to sense intracellular danger signals through special NOD-like receptors or NLRs. They include NLRP3, NLRC4, AIM2 and NLRP6. They are involved in recognizing diverse microbial (bacteria, viruses, fungi and parasites), stress and damage signals, which result in direct activation of caspase-1, leading to secretion of potent pro-inflammatory cytokines and pyroptosis. NLRP3 is the most studied antimicrobial immune response inflammasome. Recent studies reveal expression of inflammasomes in innate immune response cells including monocytes, macrophages, neutrophils, and dendritic cells. Inflammasome deficiency has been linked to alterations in the gastrointestinal microflora. Alterations in the microbiome population and/or changes in gut permeability promote microbial translocation into the portal circulation and thus directly to the liver. Gut derived lipopolysaccharides (LPS) play a significant role in several liver diseases. Recent advancements in the sequencing technologies along with improved methods in metagenomics and bioinformatics have provided effective tools for investigating the 10(14) microorganisms of the human microbiome that inhabit the human gut. In this review, we examine the significance of inflammasomes in relation to the gut microflora and liver. This review also highlights the emerging functions of human microbiota in health and liver diseases.

Aim: Outcomes of bladder exstrophy patients were studied in numerical terms using scoring systems for continence and health-related quality of life (HRQOL), along with renal function, in short-term follow up., Patients and Methods: Patients who had undergone bladder-preserving exstrophy repairs, either staged or as a single procedure, and those who had been managed by bowel augmentation were included. Continence was assessed according to five variables (max. score 15) and HRQOL assessment was by means of a structured modified questionnaire scored on a Likert-scale model (max. score 150)., Results: A total of 39 patients were followed. Mean age was 8.3 years and mean follow up duration 3 years. Mean HRQOL score was 107.55 (83-133, SD ± 19.31). Mean continence score was 8.73 (6-11, SD ± 1.544)., Conclusions: Evaluation of bladder exstrophy outcomes should not be done merely by reporting the length of dry intervals. If performed in numerical terms as outlined in this series, patients across centres will be comparable over a common assessment protocol. Continence score achieved in this series was low in comparison to the literature due to the strict evaluation protocol., (Crown Copyright © 2012. Published by Elsevier Ltd. All rights reserved.)

Cystic caecal duplication is a rare congenital anomaly. We report a case of an infant, who presented with bilious vomiting and abdominal distension. On ultrasonography, intussusception with a cyst as a lead point was present in the right iliac fossa. On exploration, there was no evidence of intussusception, only caecal duplication cyst was found. To date, only three cases of caecal duplication which mimicked intussusception have been reported in the English literature.

Aim: To evaluate the health related quality of life (HRQOL) after endoscopic injection treatment for vesico ureteral reflux (VUR) in children., Materials and Methods: Fifty four children received treatment and were prospectively evaluated for their quality of life scores, according to resolution of reflux on cystograms and status of renal scars., Results: Of the 81 refluxing units, 72 (89%) had resolution of reflux whereas 9 (11%) did not resolve. The total average QOL was higher for the patients in the resolved group as compared to the non resolved group. Comparison of pre and post procedure renal DMSA scans in 44 patients showed status quo in 26, regression of scars in six, progression in two and formation of new scars in 6. The total increase in HRQOL was highest in regression group (67.91), and lowest in progression group (36.45)., Conclusions: Successful endoscopic treatment of VUR is associated with improved quality of life, as indicated by higher HRQOL scores in the resolved group.

Adrenocortical carcinoma (ACC) is a rare malignancy in children. Most of these are endocrinologically active tumors, with virilizing features being typically dominant. Its presentation with isolated Cushing syndrome is rare. We report a 3-month-old infant with Cushing syndrome without the clinical features of androgen or mineralocorticoid excess consequently diagnosed with ACC. We discuss the different presentations, diagnosis, and management of this rare tumor with a rarer presentation.

Neonatal paraesophageal hernia with intrathoracic gastric volvulus is very rare in the newborn period. We report a case of a 2-day-old term neonate who presented with an antenatal diagnosis of paraesophageal hernia. We discuss the diagnosis and management with classical radiological features including an antenatal diagnosis of this extremely rare surgical cause of neonatal nonbilious emesis.

Aim: To determine the usefulness of infra-umbilical mini-vesicostomy in infants with posterior urethral valves (PUV), in developing countries. This new technique facilitates clean intermittent catheterization (CIC) and overnight bladder drainage, which have been effectively used for the treatment of valve bladders in the developed world., Methods: A retrospective analysis of the records of three infants who underwent a mini-vesicostomy between 2005-2009 was done. All were put on CIC in the neonatal period. Monitoring of renal parameters, bladder function and structural changes in the bladder was done before and after 4 years of CIC., Results: All three showed a decrease in upper tract dilatation, improvement in cortical function and improvement of bladder compliance at the end of 4 years. Two patients are on CIC through vesicostomy and can pass a good stream of urine per urethraly, and in one the vesicostomy has been closed., Conclusion: Mini-vesicostomy is a useful option to allow CIC on a long-term basis in children with PUV. There were no complications with this technique in this small group of patients, and it has been well accepted by their families., (Copyright © 2010 Journal of Pediatric Urology Company.

Purpose: Gastric perforations generally develop in neonates with esophageal atresia (EA) and a tracheoesophageal fistula (TEF), requiring preoperative mechanical ventilation. To the best of our knowledge, spontaneous gastric perforation in patients who have not been treated with mechanical ventilation has not been described in the literature. There is also no current consensus or treatment protocol available for the management of these patients., Methods: Over a period of 6 years, six patients with EA and TEF presented with gastric perforation at our center. We studied the clinical presentation, initial resuscitation, surgical management, and outcome of these six patients., Results: Out of the six patients, five were treated with initial flank drain insertion for peritoneal decompression. In all of the patients, a thoracotomy was performed first, followed by a laparotomy for closure of the stomach perforation. Four of the six patients survived and were discharged uneventfully. Two patients died of sepsis. Early feeding was established in all of the patients., Conclusions: Spontaneous gastric perforation can occur in patients with EA and TEF even without mechanical ventilation. Initial stabilization with peritoneal drain insertion and subsequent thoracotomy for esophageal anastomosis followed by laparotomy for stomach repair, both done in a single sitting, should be the ideal management of such patients.

Background: Transanal Swenson's operation is a relatively new single-stage procedure for Hirschsprung's disease. The results of this procedure at our centre are presented., Patients and Methods: Seventeen patients of recto-sigmoid Hirschsprung's disease underwent single-stage transanal Swenson's procedure. The diagnosis was based on the evidence of a transition zone on barium enema examination. A full thickness incision was made on the rectal wall posteriorly, 0.5 cm above the dentate line. The mobilised segment was resected about 5 cm above the transition zone. Frozen sections were performed whenever the transition zone was not clearly seen intra-operatively. The operation was completed by full thickness colo-anal anastomosis., Results: There were fourteen male and three female patients. The ages of the patients ranged from two months to eight years (median 14 months). The median hospital stay was four days (range four to seven days). Two patients required additional abdominal mobilisation. The anatomical transition zone as seen intra-operatively correlated with the pathological transition zone in all the cases. Two patients had episodes of post-operative enterocolitis and the other two patients developed stricture of the anastomosis. The follow-up period ranged from six to 45 months (Mean 35.4 months). Post-operative soiling was observed in all the patients and lasted from two to six weeks (Mean 3.4 weeks). There were no injuries to the surrounding structures. No patient had voiding disturbances and post-void residual urine was normal in all the patients. Initial increased frequency of bowel movements had settled to one to three per day., Conclusions: Transanal Swenson's pull through not only avoids laparotomy, but also the problems associated with the muscular cuff of transanal endorectal pull-through. The anatomical transition zone can be safely utilised to decide the resection limits. By a meticulous technique of dissection, injury to the surrounding structures can also be avoided.

Background: Cannabinoids are known to reduce intestinal inflammation. Atypical cannabinoids produce pharmacological effects via unidentified targets. We were interested in whether the atypical cannabinoid O-1602, reportedly an agonist of the putative cannabinoid receptor GPR55, reduces disease severity of dextran sulfate sodium (DSS) and trinitrobenzene sulfonic acid (TNBS)-induced colitis in C57BL/6N and CD1 mice., Methods: DSS (2.5% and 4%) was supplied in drinking water for 1 week while TNBS (4 mg) was applied as a single intrarectal bolus., Results: Both treatments caused severe colitis. Injection of O-1602 (5 mg/kg intraperitoneally) significantly reduced macroscopic and histological colitis scores, and myeloperoxidase activity. The protective effect was still present in cannabinoid receptor 1 (CB₁) and 2 (CB₂) double knockout mice and mice lacking the GPR55 gene. To investigate a potential mechanism underlying the protection by O-1602 we performed neutrophil chemotactic assays. O-1602 concentration-dependently inhibited migration of murine neutrophils to keratinocyte-derived chemokine (KC), N-formyl-methionyl-leucyl-phenylalanine (fMLP), and the N-formyl-peptide receptor ligand WKYMVm. The inhibitory effect of O-1602 was preserved in neutrophils from CB₁/CB₂ double knockout and GPR55 knockout mice. No differences were seen in locomotor activity between O-1602-treated and control mice, indicating lack of central sedation by this compound., Conclusions: Our data demonstrate that O-1602 is protective against experimentally induced colitis and inhibits neutrophil recruitment independently of CB₁, CB₂, and GPR55 receptors. Thus, atypical cannabinoids represent a novel class of therapeutics that may be useful for the treatment of inflammatory bowel diseases., (Copyright © 2010 Crohn's & Colitis Foundation of America, Inc.)

Scintigraphic differentiation between acute torsion, hydrocele and testicular or scrotal abscess can be difficult. Doppler sonography may provide useful complimentary information toward diagnosis. The authors describe a 5-year-old child where epididymitis with hydrocele was misdiagnosed as testicular torsion on scrotal scintigraphy.

Background: Foreign body aspirations (FBA) in the tracheobronchial tree must be suspected in children who present with a witnessed history of choking or respiratory distress of sudden onset and asymmetric breath sounds, even in the absence of pathognomonic radiographic findings. This study reviews our experience with a variety of FBA and outlines the salient differences in the literature., Methods: One hundred eighty-four consecutive children with a history suggestive of FBA undergoing bronchoscopy over a period of 10 years were reviewed. In all of the cases, rigid bronchoscopy was performed under general anesthesia using a Storz ventilating bronchoscope with the aid of optical forceps., Results: In 166 (90.21%) patients, a foreign body (FB) was discovered, whereas in 18 (9.78%) children, no FB could be found. The highest incidence of FBA (126/166, 75.9%) was found in the age group between 1 and 5 years. FBA of organic origin were more common (77.77%) in the younger patients (<3 y) as compared with the older patients (12.23%, >3 y) (P<0.0001). The radiographs were suggestive in 90% of the children >5 years of age (P<0.0063). Seven patients had a delay in the diagnosis and were being treated for various medical ailments. The incidence of FBA was almost double (64.83%) during the winter months as compared with rest of the year (34.17%). Pen cap aspirations were seen in 7 patients, and 6 of them could be extracted successfully with bronchoscopy. Two patients died., Conclusions: Bronchoscopy can be a life-saving procedure and is safe even when no FB is found. The parameters of the history of witnessed choking, respiratory distress of sudden onset, and the asymmetric breath sounds are used in the decision making to perform a bronchoscopy. Radiographs are less helpful in younger patients. Nonorganic FBA is more common in older children. There may be seasonal variations and more attention should be given to small children during the times of high incidence.

Background: Attenuated innate immune responses to the intestinal microbiota have been linked to the pathogenesis of Crohn's disease (CD). Recent genetic studies have revealed that hypofunctional mutations of NLRP3, a member of the NOD-like receptor (NLR) superfamily, are associated with an increased risk of developing CD. NLRP3 is a key component of the inflammasome, an intracellular danger sensor of the innate immune system. When activated, the inflammasome triggers caspase-1-dependent processing of inflammatory mediators, such as IL-1β and IL-18., Methods: In the current study we sought to assess the role of the NLRP3 inflammasome in the maintenance of intestinal homeostasis through its regulation of innate protective processes. To investigate this role, Nlrp3(-/-) and wildtype mice were assessed in the dextran sulfate sodium and 2,4,6-trinitrobenzenesulfonic acid models of experimental colitis., Results: Nlrp3(-/-) mice were found to be more susceptible to experimental colitis, an observation that was associated with reduced IL-1β, reduced antiinflammatory cytokine IL-10, and reduced protective growth factor TGF-β. Macrophages isolated from Nlrp3(-/-) mice failed to respond to bacterial muramyl dipeptide. Furthermore, Nlrp3-deficient neutrophils exhibited reduced chemotaxis and enhanced spontaneous apoptosis, but no change in oxidative burst. Lastly, Nlrp3(-/-) mice displayed altered colonic β-defensin expression, reduced colonic antimicrobial secretions, and a unique intestinal microbiota., Conclusions: Our data confirm an essential role for the NLRP3 inflammasome in the regulation of intestinal homeostasis and provide biological insight into disease mechanisms associated with increased risk of CD in individuals with NLRP3 mutations., (Copyright © 2010 Crohn's & Colitis Foundation of America, Inc.)

Background: A significant number of esophageal atresia and tracheoesophageal fistula patients have long gaps and a high propensity to leak. Anastomotic leak in esophageal atresia is associated with a significant morbidity and mortality., Aim: In a prospective randomized trial, we analyzed the risk factors leading to anastomotic dehiscence and studied the effect of pleural wrap as an additional vascular cover around the esophageal anastomosis., Materials and Methods: Forty patients were divided into two groups A and B randomly. In 20 patients of group A, pleural wrap was utilized for covering the anastomosis and in 20 patients of group B, no such wrap was utilized., Results: Both the groups were comparable regarding age, sex, weight, gap length, tension at anastomosis and the hospital stay. The overall leak rate was 25% (10/40) in both the groups. The leak rate was not significantly different in two groups whenever a gap length was less than 2 cm or more than 3 cm. However, for a gap length of 2-3 cm, the leak rate in group A was 18% (2/11) and in group B was 50% (4/8) (P = 0.05). Thirty percent (3/10) of patients, whose anastomosis was under tension, leaked in group A as compared to 75% (6/8) in group B patients (P = 0.001)., Conclusions: Use of pleural wrap was associated with less anastomotic dehiscence in patients with moderate gap esophageal atresia (2-3 cm) especially when the anastomosis was under tension.

Covered exstrophy is a rare variant of the exstrophy-epispadias complex. We report a female newborn with covered exstrophy, absent anal opening and duplication of the introitus and the lower vagina. This rare, previously unreported, combination of anomalies highlights the complexity of the embryological events in the caudal area during separation of the hindgut and allantois.

Variants of cloaca and exstrophy are difficult to explain and manage. We describe a female neonate having partial umbilical exstrophy with a cecal patch in the bladder and an intact distal hindgut that was expressed as a cloaca. The baby was managed by ileostomy and bladder closure without separating the cecal patch from the bladder. The possible embryological origin of this abnormality is discussed, and the literature is reviewed., (Copyright © 2011 Elsevier Inc. All rights reserved.)
