RESUMO

BACKGROUND: A three-dose, oral rotavirus vaccine (Rotavac) was introduced in the universal immunization program in India in 2016. A prelicensure trial involving 6799 infants was not large enough to detect a small increased risk of intussusception. Postmarketing surveillance data would be useful in assessing whether the risk of intussusception would be similar to the risk seen with different rotavirus vaccines used in other countries. METHODS: We conducted a multicenter, hospital-based, active surveillance study at 27 hospitals in India. Infants meeting the Brighton level 1 criteria of radiologic or surgical confirmation of intussusception were enrolled, and rotavirus vaccination was ascertained by means of vaccination records. The relative incidence (incidence during the risk window vs. all other times) of intussusception among infants 28 to 365 days of age within risk windows of 1 to 7 days, 8 to 21 days, and 1 to 21 days after vaccination was evaluated by means of a self-controlled case-series analysis. For a subgroup of patients, a matched case-control analysis was performed, with matching for age, sex, and location. RESULTS: From April 2016 through June 2019, a total of 970 infants with intussusception were enrolled, and 589 infants who were 28 to 365 days of age were included in the self-controlled case-series analysis. The relative incidence of intussusception after the first dose was 0.83 (95% confidence interval [CI], 0.00 to 3.00) in the 1-to-7-day risk window and 0.35 (95% CI, 0.00 to 1.09) in the 8-to-21-day risk window. Similar results were observed after the second dose (relative incidence, 0.86 [95% CI, 0.20 to 2.15] and 1.23 [95% CI, 0.60 to 2.10] in the respective risk windows) and after the third dose (relative incidence, 1.65 [95% CI, 0.82 to 2.64] and 1.08 [95% CI, 0.69 to 1.73], respectively). No increase in intussusception risk was found in the case-control analysis. CONCLUSIONS: The rotavirus vaccine produced in India that we evaluated was not associated with intussusception in Indian infants. (Funded by the Bill and Melinda Gates Foundation and others.).

RESUMO

PURPOSE: Distal shunt tube migration following ventriculoperitoneal (VP) shunt placement in children is mostly managed by an initial shunt diversion/removal and subsequent replacement. Lately, shunt salvage is being used as an alternative in certain conditions. We have focused on the situations where one can consider or disregard shunt salvage in such cases. METHOD: A retrospective study of children treated for distal shunt migration following VP shunt placement between January 2013 and December 2019. RESULT: Seventeen children were managed for over 7 years. These included cutaneous extrusions (n = 4), hollow viscus perforation (n = 6), inguinal hernias (n = 5), and umbilical extrusion (n = 2). The surgical treatment varied from a cutaneous wound closure (with a tube in situ), temporary external shunt diversion, and laparotomy with shunt reposition into the peritoneal cavity. Shunt salvage was possible in three cases, whereas in 2 cases even though shunt salvage was possible, it was not feasible due to a short residual shunt length. CONCLUSION: VP shunt salvage is possible in certain cases of distal shunt migration with a functional uninfected shunt. Small cutaneous extrusions can be covered by a local skin flap. Also, one should consider the residual intraperitoneal shunt length before its salvage in small children.

RESUMO

AIM: The aim of the study was to highlight the etiology, spectrum of presentation, and management of isolated penile trauma in boys. METHODS: A retrospective review of boys treated for isolated penile trauma between January 2015 and June 2019 at a tertiary-level hospital. RESULTS: Nine children were admitted over 4½ years. Etiology: The mechanism of penile injury (PI) was penile hair tourniquet (n = 5), postcircumcision (n = 2), dog bite (n = 1), and scald injury (n = 1). Extent of injury includes complete urethral transection at corona (n = 4); loss of urethral plate in a case of hypospadias (n = 1); complete loss of glans (n = 1); penile transection at corona (n = 1); total penile amputation (n = 1); and deep partial-thickness burns of penile shaft and adjacent suprapubic skin (n = 1). Management: One patient absconded. The remaining patients were managed as follows: calibration of urethral meatus (n = 1); penile burn was managed with dressing and antibiotics; coring of glans with urethral end-end anastomoses (n = 4); Bettocchi's quadrangular lower abdominal flap phalloplasty (n = 1); and Bracka's staged urethroplasty (n = 1). Complications include wound infection following trauma (n = 4), postsurgical infection (n = 3), urethrocutaneous fistula (n = 2), and reapplication of penile hair tourniquet (n = 1). CONCLUSION: Isolated PI in boys is not uncommon. Most are preventable if the parents are apprized and watchful. The clinician should also be vigilant regarding child maltreatment. A staged approach tailored to the type of injury provides a satisfactory outcome.

RESUMO

AIMS: The aim of the study was to report a new technique of ergonomic penile skin-dartos management during buccal mucosa graft (BMG) to provide adequate penile skin-dartos for neourethral coverage at the time of second-stage tubularization. MATERIALS AND METHODS: Ten proximal hypospadias with severe chordee underwent first-stage surgery with a new technique. An incision along the urethral plate margin and preputial edge was used to split inner prepuce off preputial dartos and penile degloving leaving inner prepuce attached to corona. Urethral plate was divided into the subfascial plane. Penile dartos was bisected in the dorsal midline. Distal half of penile skin-dartos bifurcated and joined to inner preputial edges. Mobilized and lateralized penile skin-dartos was sutured flanking edges of BMG. The second-stage tubularization after 6 months provided neourethral double dartos coverage with eccentric suture lines. RESULTS: Adequate dartos for neourethral coverage during second-stage tubularization was available in all. Subcoronal urethrocutaneous fistula occurred in one that was repaired. CONCLUSIONS: Ergonomic management of inner-preputial skin and ventral transfer of penile skin-dartos helps in providing neourethral coverage during subsequent second-stage tubularization to minimize the occurrence of complications.

RESUMO

Tourniquet syndrome is a rare condition where a tourniquet applied to an appendage leads to an obstructed blood flow and subsequent ischemic injury. Meningomyelocele and meningocele are common birth defects, and involvement of meningocele in tourniquet syndrome is never mentioned in the literature. We managed a 10-day-old male child presenting with infected lumber meningocele with a tourniquet tied at its base. It is being presented with review of relevant literature.

RESUMO

INTRODUCTION: Giant occipital encephalocele (GOE) is a term used when the size of the OE is greater than or equal to the size of the head. It has been limited to case reports, with only sporadic exclusive series. This is a series of GOE managed at our center over time with emphasis on practical problems faced in management. MATERIALS AND METHODS: This was a retrospective observational study. The patients were evaluated for the age of presentation, sex, and head size. Any associated neural tube defect was also looked for. Imaging was used for associated brain anomalies and to plan the surgical procedure. The requirement of ventriculoperitoneal (VP) shunt was also assessed. RESULTS: During the study period of 7 years, 11 patients of GOE were admitted. Apart from one, all other patients were <1 year of age. Nine patients underwent surgical intervention, which included excision and repair of swelling with or without VP shunt placement. The content of the sac was only cerebrospinal fluid (CSF) in six patients and CSF and gliotic brain tissue in remaining patients. The attendants of two patients did not give consent for surgery and left against medical advice. CONCLUSION: GOE is an uncommon entity with limited information about management. Careful evaluation, proper imaging of patient, and care during intraoperative and postoperative periods with emphasis of factors determining the prognosis may provide satisfactory results.

RESUMO

BACKGROUND: Infantile hemangioma is the most common tumor of infancy. Currently, propranolol is a preferred drug for treating hemangioma. The exact mechanism of action of propranolol is not known. In this study, we attempted to assess whether propranolol has any effect on vascular endothelial growth factor (VEGF) and tissue inhibitor of metalloproteinase-2 (TIMP-2) over a period of time, and if it is there, how long it affects it. MATERIALS AND METHODS: Propranolol was administered in the dosage of 2-3 mg/kg. The first serum sample was collected before starting the propranolol treatment. Thereafter, samples were collected at monthly intervals up to a total of six samples. The samples were assessed for TIMP-2 and VEGF using enzyme-linked immunosorbent assay kit. RESULTS: The duration of this study was from June 2016 to November 2017. The total number of patients in this study was 15. Thirteen patients responded to treatment. The mean age of patients was 7.1 months. The mean value of baseline VEGF was 0.234 ± 0.059 and that of TIMP-2 was 1.338 ± 0.679. As compared to baseline value, the P value was statistically not significant in any of sequential values. In category-wise analysis, apart from statistically significant value in the 6th month in excellent category and good response category in the 1st month, all other values did not reveal any significant change in VEGF analysis. The analysis of TIMP-2 revealed a significant change in the levels from Sample 2 to Sample 6 in the excellent response group; however, the levels did not show a specific trend either increasing or decreasing. CONCLUSION: Despite its beneficial action in regression of hemangioma, the exact mechanism is yet to be identified. The exact duration of treatment needs further evaluation.

RESUMO

BACKGROUND: Meconium ileus (MI) is defined as an intestinal obstruction caused by the impaction of inspissated meconium in the terminal ileum. In this study, we have evaluated the nonoperative management of patients of simple MI without fluoroscopic support -an important requisite of the Noblett's criteria. Besides this, surgical management in cases of failed conservative management and complicated MI was also assessed. MATERIALS AND METHODS: This was a retrospective observational study. Various clinical and radiological parameters were evaluated. Conservative management included the use of water-soluble contrast diatrizoate meglumine and diatrizoate sodium. In case of nonpassage of meconium in 24 h from first intervention, exploratory laparotomy with ileostomy was performed. All complicated MI underwent exploratory laparotomy with creation of stoma as and when needed. RESULTS: The duration of this study was 6½ years. Twenty-five neonates of MI were admitted. Of these, 22 had simple MI and remaining three had complicated MI. Eighteen neonates responded to the conservative management. In four neonates, who did not respond, exploratory laparotomy was performed. All three neonates having complicated MI underwent exploratory laparotomy. One patient expired in follow-up. CONCLUSION: MI is an important neonatal emergency, which needed immediate attention of a pediatric surgeon. Proper evaluation of the patient, careful application of principals of conservative management, and timely surgical intervention may fetch satisfactory results.

RESUMO

AIM: The aim of this study is to report the technique and outcome of ischiopubic (IP) osteotomy for pelvic ring closure in classic exstrophy bladder. METHODS: A total of 85 male classic exstrophies were selected based on trapezoid-shaped space between IP ramus on three-dimensional computed tomography pelvis. Using midline scroto-perineal approach, after bladder plate mobilization and radical corporal detachment; the pelvic surface of superior pubic ramus (SPR) was exposed. Above the obturator canal, H-shaped incision was made on periosteum of the SPR. The horizontal line of H was placed above the obturator canal. Rectangular periosteal flaps above and below the horizontal line was raised. In the subperiosteal plane, curved hemostats encircled the SPR that were divided using a bone drill. On the medial aspect of ischial tuberosity, a notch was created as hinge using a bone drill. Forks of bone holding forceps hooked the pubic bone and tightened for its midline approximation, lengthening of the SPR and inward rotation of IP ramus. Linea alba and pubic bones were approximated with interrupted Polygalactin sutures. RESULTS: Midline approximation of pubic bone and linea alba was possible in all. There was no injury to obturator nerve, vessels, or other structures . CONCLUSIONS: IP osteotomy is the safe and effective technique of pelvic ring closure in patients with specific pelvic configuration.

RESUMO

Congenital ranula is rare. We report a large, symptomatic, congenital plunging ranula associated with a salivary gland cyst in the neck. To the best of our knowledge, this is the first such reported case. Even though both the cysts had their origin from the sublingual gland, only the cervical cyst had a capsular covering. Herniation of a part of the immature sublingual gland anlage through a congenital mylohyoid defect, its separation, and subsequent maturation could explain this occurrence.

RESUMO

AIM: To evaluate the outcome of innervation preserving sphincteroplasty along with anatomical bladder neck reconstruction (IPS-ABNR) compared to classic Young-Dees-Leadbetter (YDL) bladder neck reconstruction in exstrophy with insufficient bladder capacity requiring detubularized-ileocystoplasty. MATERIALS AND METHODS: Sixteen male patients of exstrophy bladder who required ileocystoplasty from 2004 to 2010 were randomized into group A (n = 7) and group B (n = 9). After detubularized-ileocystoplasty with Mitrofanoff stoma and ureteric reimplantation in all, group A received YDL bladder neck repair while group B received IPS-ABNR repair through a midline scrotoperineal approach. Outcome measurement included operative and postoperative problems, continence, and upper tract status. RESULTS: In group A, two had incompetent bladder neck with gross incontinence, while four had a dry interval of more than 3 h without the ability of voiding per urethra. In group B, seven patients had dry interval of more than 3 h with an ability of urethral voiding and midstream holding in five. CONCLUSIONS: Exstrophy patients requiring augmentation cystoplasty and repaired with IPS-ABNR can achieve dynamic bladder outlet resistance with adequate leak point pressure and ability to void voluntarily with midstream holding capability. The children had the satisfaction of voiding per urethra with ability to stop in midstream similar to that in normal children.

RESUMO

AIM: Congenital lumbar hernia is an uncommon anomaly with only few cases reported in the English literature. This study was done to study the incidence, associated conditions, management and complications of congenital lumbar hernia repair in paediatric patients. METHODS: Retrospective study of all patients over a period of 20 years (January 1990 to January 2010) was analysed. RESULTS: A total of 18 patients (two bilateral hernias) were encountered in this series. All were in the age group of 1 day to 6 years. All the patients were operated by open technique. Primary repair was done in 14 patients and prosthetic meshplasty in two. Two patients could not be operated. The average follow-up period was 3 years. There was no follow-up loss in our study. There was no evidence of recurrence in this series. CONCLUSION: Up until now, the total number of cases is 68. The large size of hernia defect (>10 cm) may determine the use of prosthetic mesh repair. Proper surgical treatment, either primary repair or hernioplasty, provides adequate management of this condition.

RESUMO

INTRODUCTION: Congenital pouch colon (CPC) is a pouch-like dilatation of shortened colon associated with anorectal malformation (ARM). The disease is prevalent in northern India. Postoperatively, the continence results are not as good as in other ARMs and there is higher incidence of incontinence and perineal soiling in these patients. The present study aimed to evaluate the pelvic floor and sphincter muscle characteristics in patients of CPC with the help of 64-slice computerized tomography with three-dimensional (3D) volumetric reconstructions of images, thus, to know the overall quality of these muscles in the patients. MATERIALS AND METHODS: The study was conducted in patients admitted over a period of July 2007 to November 2008 in our department. Totally, eight patients of CPC were subjected to 64-slice CT with three-dimensional reconstructions of images and different parameters such as quality of pelvic floor muscles, configuration of vertical and parasagittal fibres, shape and thickness of sphincter muscle complex, attenuation values of sphincters were studied. RESULTS: The 3D reconstructed images of pelvis in patients of CPC showed a well-developed pelvic floor and sphincter muscle complex. The length of the parasagittal fibres, transverse width of the vertical fibres and CT attenuation values of these structures with overall muscle quality were found to be good in these patients. CONCLUSION: In cases of CPC, the pelvic floor muscles including striated muscle complex (vertical and parasagittal fibres) are well developed. Higher rates of incontinence and soiling in CPC are not because of poorly developed pelvic floor and sphincter muscles. Three-dimensional CT can also provide important anatomical information that can help the operating surgeon while performing surgery.

RESUMO

Background: To present a case series of children with eventration of diaphragm who underwent thoracoscopic repair highlighting the technical points and surgical modifications to prevent a recurrence. Settings and Design: This is an observational study of patients with diaphragmatic eventration admitted to a tertiary care institute. The study was designed following CARE guidelines endorsed by EQUATOR Network. Pediatric patients who had undergone thoracoscopic repair between January 2010 and March 2019 were included in the study. Materials and Methods: Age at surgery, gender, weight, site of the lesion, operating time, need for postoperative drain, and complications were assessed. Results: Twenty-six patients had thoracoscopic repair of the eventration of diaphragm. The male-female ratio was 12:1 and mean weight at the time of surgery was 6.3 kg (2.2-22 kg) with most patients having left side congenital diaphragmatic eventration (n = 21) as compared with the right side (n = 5). The average operating time was 66 minutes (37-144 minutes). Conclusions: Diaphragm plication by a thoracoscopic approach is safe and feasible in neonates and pediatric patients.

RESUMO

AIM: To evaluate the role of nebulized N-acetyl cysteine (NAC) in liquefying the airway secretions and improving the outcome of patients of esophageal atresia with tracheoesophageal fistula (EA + TEF). METHODS: It was a non-randomized interventional study. Two milliliters of 10% NAC was given in a nebulized form (2:5 dilution, every six hourly) to patients of ET + TEF, along with regular suction of upper esophageal pouch. The group was compared with control, which comprised patients of EA + TEF receiving only saline nebulization. The consistency of the secretions was compared by hand held consistometer in unit of time (seconds) required to cross a predetermined distance along with gravity. RESULTS: Sixty patients were assessed. Of these, 30 patients were present in both groups. The study group showed significant (p = 0.01-0.0001) decrease in consistency of secretions from the control group after day 2 of NAC nebulization. Patients' discharge was significantly (p = 0.01) earlier in cases. There was no significant (p = 0.41) difference in mortality between the groups. No specific adverse effects were observed in the study group. CONCLUSION: It appears that nebulized NAC decreases the consistency of secretions in EA + TEF patients. It is interesting to note that the group of patients that received NAC was discharged earlier than the control group and had a higher survival rate than the control group. Whether this is directly attributable to the use of NAC is unknown. A prospective double-blinded randomized clinical trial is warranted to confirm these results. LEVEL OF EVIDENCE: Level II, prospective comparative study (non-randomized).

RESUMO

OBJECTIVE: Intussusception has been linked with rotavirus vaccine (RVV) as a rare adverse reaction. In view of limited background data on intussusception in India and in preparation for RVV introduction, a surveillance network was established to document the epidemiology of intussusception cases in Indian children. METHODS: Intussusception in children 2-23 months were documented at 19 nationally representative sentinel hospitals through a retrospective surveillance for 69 months (July 2010 to March 2016). For each case clinical, hospital course, treatment and outcome data were collected. RESULTS: Among the 1588 intussusception cases, 54.5% were from South India and 66.3% were boys. The median age was 8 months (IQR 6, 12) with 34.6% aged 2-6 months. Seasonal variation with higher cases were documented during March-June period. The most common symptoms and signs were vomiting (63.4%), bloody stool (49.1%), abdominal pain (46.9%) and excessive crying (42.8%). The classical triad (vomiting, abdominal pain, and blood in stools) was observed in 25.6% cases. 96.4% cases were diagnosed by ultrasound with ileocolic location as the commonest (85.3%). Management was done by reduction (50.8%) and surgery (41.1%) and only 1% of the patients' died. 91.1% cases met Brighton criteria level 1 and 3.3% Level 2. Between 2010 and 2015, the case load and case ratio increased across all regions. CONCLUSION: Intussusception cases have occurred in children across all parts of the country, with low case fatality in the settings studied. The progressive rise cases could indicate an increasing awareness and availability of diagnostic facilities.

RESUMO

AIM: Establishment of baseline epidemiology of intussusception in developing countries has become a necessity with the possibility of reintroduction of rotavirus vaccine. The current study assessed the seasonal trend in cases admitted with intussusceptions and dehydrating acute watery diarrhoea in children aged 2 months to 10 years. METHODS: In a prospective surveillance study, teaching and research hospital sites in India (Lucknow and Nagpur), Brazil (Fortazela), Egypt (Ismailia) and Kenya (Nairobi) established a surveillance where a network of hospitals with surgical facilities catered to a reference population of about 1-2 million for reporting of intussusception. One large hospital per site also recruited admitted cases of acute watery diarrhoea. RESULTS: From April 2004 to March 2006, 173 and 2346 cases of intussusception and diarrhoea, respectively, were recruited. Cases of intussusception had no apparent seasonality. Most cases of intussusception (61.3%) (107/173) were in the < or =1 year age group, with males comprising 68.8% (119/173) of all cases. Hospital mortality of intussusception was 4.2% (4/96). Cases of diarrhoea peaked in March, with 56.6% (1328/2346) of admitted cases being males. Majority (83.1%) of cases of diarrhoea had received antibiotics, and the hospital mortality was 0.8% (18/2280). CONCLUSION: Intussusception in the four participating countries exhibited no seasonal trend. We found that it is feasible to establish a surveillance network for intussusception in developing countries. Future efforts must define population base before the introduction of rotavirus vaccine and continue for some years thereafter.

RESUMO

BACKGROUND: 5alpha-Reductase deficiency (5RD) is an uncommon autosomal recessive disorder of sexual differentiation. It results from impaired conversion of testosterone to dihydrotestosterone due to mutations in the steroid 5alpha-reductase type 2 gene (SRD5A2). Mutations in SRD5A2 have not been previously reported in Indian patients with 5RD. AIM: To delineate the clinical features and mutations in the SRD5A2 gene in Indian patients with 5RD. PATIENTS AND METHODS: The SRDSA2 gene was sequenced in two unrelated patients with elevated testosterone/dihydrotestosterone ratio and in one patient with classical clinical features and virilization at puberty (in whom the ratio could not be measured due to prior gonadectomy). The prevalence of SRD5A2 mutations was also studied in 52 healthy ethnic control subjects by PCR-RFLP. RESULTS: Two patients, both from the north Indian state of Uttar Pradesh, carried the homozygous missense mutation p.R246Q in exon 5. Parents of both probands were heterozygous for the mutation. The mutation was absent in 52 control subjects. The third patient, with severe perineoscrotal hypospadias and micropenis, was detected to have a novel heterozygous missense mutation p.Q56H, as well as the homozygous polymorphism p.V89L, both in exon 1. The p.Q56H mutation was absent in 52 control subjects. CONCLUSION: p.R246Q is a common SRD5A2 mutation in 5RD patients from the Indian subcontinent.

RESUMO

PURPOSE: The purpose of this article is to report our experience in the management of 18 patients with melanotic neuroectodermal tumor of infancy involving the maxillary alveolus. PATIENTS AND METHODS: All patients presented with hard nontender swelling involving the upper alveolus with facial deformity. Analysis included hematocrit, coagulation profile, serum creatinine, and screening for vanillyl mandelic acid and catecholamines. Imaging studies included x-ray of the maxilla and chest, ultrasound of the abdomen, computed tomography scan (1990 to 1999), and magnetic resonance imaging (after 1999). All surgeries were performed using endotracheal anesthesia, and complete gross excision of the tumor was achieved with coverage of the defect with mucoperiosteal flaps. All specimens were subjected to histopathology and immunohistochemistry. RESULTS: The expansion of the alveolus produced by the tumor improved in 4 to 6 months. Subsequent dentition was affected by the removal of involved tooth buds during the operation. All the patients are in regular follow-up (maximum 206 months) and there has been no local recurrence or distant metastasis. Mean follow-up time was 130.8 months (95% confidence interval, 168.8-210.6). Overall survival at 17 years was 85.6%. Median survival could not be established due to statistically insignificant sample size, while mean survival time was 189.7 months (95% confidence interval, 103.7-157.8). CONCLUSIONS: In the absence of metastatic disease, melanotic neuroectodermal tumors of infancy can be successfully managed by local excision.

RESUMO

AIMS: It was the aim of this study to report a prospective study of 110 spina bifida patients with hydrocephalus treated by simultaneous ventriculoperitoneal (VP) shunt and repair of the meningomyelocele. METHODS: Between January 2005 and February 2008, 264 patients with spina bifida were admitted to the author's department. Those patients in whom the preoperative cranial ultrasonography measurement of the bifrontal diameter was >26 mm, the bicaudate diameter >20 mm and the diameter of the body of the lateral ventricle >26 mm were predicted to develop postoperative hydrocephalus (n = 245). Of these, 110 patients underwent simultaneous (group 1) VP shunt with repair of the meningomyelocele, while 135 (group 2) underwent sequential surgery due to the preference of the attending consultant. RESULTS: Twenty-two of the 110 patients in group 1 developed complications (wound problems, cerebrospinal fluid leak, shunt malfunction, death) compared with 38 of 135 patients in group 2. The remaining patients had an uneventful postoperative and follow-up course. CONCLUSIONS: Simultaneous VP shunt with surgery for hydrocephalus was feasible in our setup. The rate of complications was not higher than in staged surgery. Single-stage repair of spina bifida with hydrocephalus offers considerable advantage in the form of a reduction in hospital burden, costs and patient morbidity.
