Evaluation of work-related musculoskeletal problems in pediatric surgeons.

PURPOSE: Pediatric surgeons are exposed to intense work-related activities, depending on their profession, including residency training. This study aims to investigate the musculoskeletal symptoms and analyze the relationship between musculoskeletal symptoms and the demographics, physical activity levels, and body mass index (BMI) of pediatric surgeons. METHODS: A total of 82 pediatric surgeons (female, 20; male, 62) were included in this study. The musculoskeletal symptoms were determined using the Cornell Musculoskeletal Discomfort Questionnaire. The levels of physical activity were determined using the International Physical Activity Questionnaire. RESULTS: The mean age of the participants was 48.97 ± 8.894 years, the mean BMI was 26.72 ± 4.12 kg/m2, and the mean working time after acquiring their specialty was 18.65 ± 9.83 years. The average surgery counts per week were 15.22 ± 12.17. Pediatric surgeons mostly complained from lower back pain, upper back pain, neck pain, and right and left shoulder pain. Surgeons with higher BMI had higher pain scores and received more treatment sessions. CONCLUSIONS: Pediatric surgeons' complaints are related to their total numbers of surgery. Higher BMI and lower physical activity seem to be the major contributing factors for developing musculoskeletal symptoms. The study results indicated that surgeons should keep their BMI levels to the optimum and increase their physical activity levels.

Risk factors, complications and outcome of cholelithiasis in children: A retrospective, single-centre review.

AIM: The aim of this study was to evaluate the clinical presentation, risk factors, complications, treatment and outcomes of cholelithiasis in children. METHODS: Children with cholelithiasis were reviewed for demographic information, predisposing factors, presenting symptoms, laboratory findings, complications, treatment and outcome, retrospectively. RESULTS: A total of 254 children with cholelithiasis (mean age: 8.9 ± 5.2 years) were recruited to the study. Girls (52.8%) were significantly older than boys (P < 0.001). Symptomatic patients (59%) were significantly older than asymptomatic patients (P = 0.002). Abdominal pain was the most frequent symptom. No risk factors were identified in 56.6% of the patients. Ceftriaxone (20%) was the most commonly associated risk factor. At presentation, at least one of the following complications was seen in 14.1% of patients: cholecystitis (10.9%), obstructive jaundice (2.7%), pancreatitis (1.96%) and cholangitis (1.2%). There was no relationship between gallstone size and symptoms, aetiological factors and complications. The cholelithiasis dissolution rate was higher in younger children (P = 0.032), in those with biliary sludge (P < 0.0001) and ceftriaxone-related cholelithiasis (P < 0.001). Haemolytic anaemia (P = 0.001) and older age (P = 0.002) were associated with stable stones. Ursodeoxycholic acid was administered to 94.4% of patients at presentation. Twenty-nine patients underwent cholecystectomy, and seven patients underwent endoscopic retrograde cholangiopancreotography. Patients who were symptomatic at presentation had significantly more frequent symptoms at follow-up (P < 0.001) CONCLUSIONS: Dissolution rate of cholelithiasis was higher in younger children, biliary sludge formation and ceftriaxone-related cholelithiasis but lower in older children and haemolytic anaemia-related cholelithiasis.

Decision for surgery in the management of a rare condition, childhood gallbladder polyps, and the role of ultrasonography.

Gallbladder polyps are tumors or tumor-like protrusions of the gallbladder. They are rarely seen in the pediatric age. Most important issue about these mostly incidental lesions is the risk of malignant transformation. Size more than 10 mm is the classicalcutoff for determining this risk, but it is rarely valid in children. Ultrasonography is the method of choice for follow-up, but it rarely demonstrates change of size or malignant transformation. Hereby, we report 6 cases of childhood gallbladder polyps, none of which had a genetic risk factor. Follow-up was uneventful in 4 of them. Two patients had undergone surgery, but none of the lesions were neoplastic. In the follow-up, a single experienced radiologist should handle the patient, in order to prevent inter-observer variation. The cut-off size for deciding surgery should be 10 mm for those cases with genetic background creating malignancy risk (metachromatic leukodystrophy, pancreaticobiliary duct abnormalities, achondroplasia, Peutz-Jeghers syndrome) or with accompanying cholelithiasis, and 15 mm for those without any risk factors to prevent any unnecessary operations.

Closing the appendicular stump with a polymeric clip in laparoscopic appendectomy: analysis of 121 pediatric patients.

INTRODUCTION: The purpose of this study was to evaluate the technical feasibility and other advantages of closing the appendicular stump with a polymeric clip in laparoscopic appendectomy (LA). METHODS: In this study, 121 pediatric patients who underwent LA between July 2009 and July 2011 were included. Age and gender of the patients, the number of clips, operative time and length of hospitalization, complications, and follow-up periods were evaluated retrospectively. RESULTS: Of appendicular stump of a total of 121 patients who were underwent LA, 71 were closed with double polymeric clips and 50 were closed with a single polymeric clip. Patients were between the ages of 3 and 15 years (mean 8.3 years). Out of the 121 patients, 54 were female and 67 were male. The duration of the operation was ranged from 13 to 55 minutes (mean 28 minutes). Of these, 83 patients were discharged in less than 24 hours. The cost of a single clip was 10 USD. The follow-up period of patients were ranged between 1 and 23 months (mean 13 months). No operative or postoperative complications occurred depending on the application of the polymeric clip. CONCLUSION: LA using polymeric clip/s to close appendicular stump in children is a safe, feasible, and inexpensive method.

CD117 and CD34 staining patterns in childhood benign mammary lesions.

OBJECTIVE: CD117 and CD34 are markers that have both been implied in cancer progression in adult breast lesions. This study was conducted in order to create a retrospective documentation and to analyze the expression patterns of these markers on childhood benign lesions along with a comparison with adult breast lesions' staining patterns. MATERIAL AND METHOD: Nine fibroadenomas, 2 tubular adenomas, 1 mammary hamartoma, 2 gynecomastias, 1 benign phyllodes tumor were retrieved from pathology archives of two reference centers between 2005-2010. RESULTS: CD117 staining was identified in the epithelium of all cases in fibroadenoma/tubular adenoma group and focally positive in 1 mammary hamartoma, 2 gynecomastias, and 1 benign phyllodes tumor. CD117 staining was detected in the stroma of 8 cases. Three fibroadenomas, 1 mammary hamartoma, 2 gynecomastias and 1 benign phyllodes tumor lacked stromal labelling for this marker. All cases were strongly and diffusely positive for CD34 except the benign phyllodes tumor case. This case presented marked loss of stromal CD34 staining when compared to the surrounding stroma. Additionally, pseudoangiomatous stromal hyperplasia was noted in 2 gynecomastias and in the peritumoral stroma of benign phyllodes tumor case. CONCLUSION: Our study demonstrated that fibroadenoma was the most commonly encountered breast lesion in childhood and that adolescent fibroadenomas showed similar staining patterns for CD117 and CD34 as for adult counterparts. On the other hand, different expression patterns of CD117 and CD34 between adenoma group and the gynecomastias and benign phyllodes tumor group may implicate different mechanisms of development and tumorigenesis among these groups.

The use of digital photos and video images taken by a parent in the diagnosis of anal swelling and anal protrusions in children with normal physical examination.

PURPOSE: The purpose of this study is to demonstrate that digital photos and video images taken by a parent can provide a definite diagnosis and makes some diagnostic procedures (eg, air contrast enema, sigmoidoscopy) unnecessary for anal swelling and anal protrusions in children with normal physical examination. METHODS: In a 41-month period (September 2007-January 2011), 23 parents brought their children to the clinic, stating that they saw a swelling in the anal region and/or that something protruded from the anus while their children were defecating. If the visual inspection of the anal region and digital rectal examination of the patients were normal, parents were asked to take photos or record videos when the lesion occurred to make a diagnosis and avoid the need for air contrast enema and/or sigmoidoscopy. The parents were also asked either to send these images to the surgeon via e-mail or bring an image or the camera to the surgeon's office. The patients age, sex, symptoms, medical history, results of their first physical examination, photos and video records, and the diagnosis and treatment were recorded. All of these information were retrospectively reviewed. RESULTS: The photos provided by 20 parents and the video records from 3 parents were assessed, and the diagnoses of all patients were confirmed. Of these 23 patients, a definitive diagnosis of rectal prolapse in 8, hemorrhoids in 10, rectal polyps in 3, and sentinel skin tag in 2 was made. In addition, the photographic and video evidence gave the clinicians an idea of the degree of rectal prolapse in patients for whom this was a problem. Three patients diagnosed with a rectal polyp underwent polyp excision. One patient with rectal prolapse who was unresponsive to medical treatment underwent laparoscopic posterior rectopexy, and all other patients received medical treatment. CONCLUSION: When a swelling or protruding anal lesion in a child is discovered by parents and visual inspection of the anal region and digital rectal examination is normal, parents should be encouraged to take photos or videos of the anal region before performing air contrast enema and/or sigmoidoscopy. These photos and videos can provide a definitive diagnosis and prevent unnecessary diagnostic procedures.

Laparoscopic cystectomy for splenic hydatid cyst: a case report.

Even in countries where it is considered endemic, splenic hydatid cyst is a very rare disease in childhood. Partial or total splenectomy has generally been the treatment of choice for this condition. This is the first report of laparoscopic cystectomy as treatment of isolated splenic hydatid cyst in childhood. A 10-year-old girl with isolated splenic hydatid cyst was successfully treated by laparoscopic cystectomy and splenic preservation. The authors have demonstrated that laparoscopic cystectomy for an isolated splenic hydatid cyst is technically feasible, safe, and is associated with a shorter hospital stay and good cosmetic appearance.

A comparison of polymer clips and endoloop applications for securing the appendiceal stump during laparoscopic surgery in children.

INTRODUCTION: In this study, for the first time in children a polymer clip and endoloop (EL) for securing an appendiceal stump have been prospectively correlated and evaluated radiologically. METHODS: Forty-nine patients aged 1 to 15 years were operated upon by the same surgeon for acute or perforated appendicitis between May 2008 and May 2009. The appendiceal stump was ligated by an EL or polymer clip. Patients were radiologically evaluated during the postoperative period. RESULTS: In the EL group, the mean operating time for perforated appendicitis was recorded as 57.40 minutes and in nonperforated appendicitis as 39.37 minutes, respectively. In the clips-applied group, these periods were 48.23 and 34.72 minutes, respectively. Clip application is 3 times cheaper than EL. CONCLUSIONS: Polymer clip is an instrument that is cheaper, safe, easily applicable, and takes less time for securing appendiceal stumps compared with EL.

External genital proportions in prepubertal girls: a morphometric reference for female genitoplasty.

PURPOSE: An understanding of normal genital anatomy is essential for a successful surgical approach and outcome in feminizing genitoplasty. We sought to establish genital standards in female children through external genital measurements taken from the end of the neonatal period until the beginning of adolescence. MATERIALS AND METHODS: This prospective study included 205 females who were anesthetized for surgery for various diagnoses between January 2007 and March 2008. Patient age ranged from 1 month to 10 years. Patients were divided into 4 age groups-1 to 12, 13 to 24, 25 to 60 and 61 to 120 months. Information on patient age, height, weight and, for patients younger than 1 year, head circumference was retrieved from patient charts. Measurements of clitoris length, clitoris width, labia majora length, left and right labia minora length and width, and perineal distance were recorded. RESULTS: Specific equations were generated using these values to estimate the expected external genital structure dimensions in girls. Length of labia majora vs age, length of labia majora vs body weight, perineal distance vs body weight, clitoral width vs body weight and clitoral length vs age reference percentile curves were prepared. CONCLUSIONS: The equations and percentile curves generated can be used as a guide in prospective feminizing genitoplasty. Furthermore, patients and their families can be informed regarding the variability of external genitalia dimensions. This information should ensure a healthier appreciation of the postoperative genitalia by patients and their families.

The evaluation of the adrenal and thyroid axes and glucose metabolism after burn injury in children.

INTRODUCTION: Burn injury is an important trauma and can cause many hormonal and metabolic changes in the human body. In contrast to the situation with adults, there are inadequate number of studies on children with this condition. Our aim in this study was to determine the changes in the adrenal, thyroid axes and glucose metabolism in the acute and subacute period and relation to the percent total body surface area (TBSA) burned in children with major burn injury. PATIENTS AND METHOD: A total of 90 hospitalized children aged 0-13 years (mean: 3.44 +/- 2.90 years) with major fluid burn injury were included in this study. Serum ACTH, cortisol, fasting glucose and insulin and thyroid hormones (free T3 and T4, TSH) were evaluated in the first 24 hours after the burn injury and on day 3 and month 3 consequently in all of the cases. An ACTH stimulation test was performed when necessary. Continuous variables were compared with analysis of variance and categorical variables were compared with the chi-square test. The Pearson correlation was used to determine the relation between ACTH and cortisol and between blood glucose and insulin (on day 1 and 3 and month 3). Also the correlation with the TBSA burned and the hormonal values were evaluated. A p value <0.05 was considered statistically significant. FINDINGS: ACTH and Cortisol level increased in first 24 hours and decreased significantly by time. The change of ACTH and Cortisol level with time was significantly related to the TBSA burned. ACTH and cortisol levels were found significantly correlated in each time-point, but the correlation was highest in 3rd month. The glucose level in the first 24 hours was significantly higher than day 3 and month 3 levels in all of the children. There was again a significant increase in the serum insulin level in the first 24 hours. However there was no difference between day 1 and 3 serum insulin levels. A correlation was found between serum glucose and insulin on the first day but not on day 3 or month 3. Free T3 and T4 levels increased by time. Pairwise comparisons indicated that 1st day free T3 and T4 level was significantly lower than both 3rd day and 3rd month levels. CONCLUSION: ACTH, Cortisol and fasting blood glucose level increased significantly however serum insulin level was slightly higher in first 24 hours after burns in children. Thyroid hormones were found to be decreased acute period following burns but staying in normal levels.

Urological problems or fecal continence during long-term follow-up of patients with anorectal malformation.

INTRODUCTION: Anorectal malformations comprise a wide spectrum of diseases. The main concerns for the surgeon in correcting these anomalies are bowel control, urinary control, and sexual function. The aim of this study was to evaluate fecal continence together with additional urinary anomalies in patients with anorectal malformations (ARM) and determine which of them is more troublesome for life quality in long-term follow-up. MATERIALS AND METHODS: A total of 93 cases followed up and treated at our clinic between 1983 and 2009 were evaluated for urinary pathologies, fecal continence, and their quality of life (QOL). Patients were classified according to the international system (Krickenbeck), and were evaluated on the basis of voluntary bowel movement, constipation, and fecal soiling. They were also classified as good, fair, and poor regarding fecal continence. The urinary system pathologies, the medical and surgical treatments received, and the pediatric nephrology follow-up results were all evaluated. The patients were grouped by age and their QOL scored using a telephone interview. RESULTS: The mean age (+/-SD) was 8.47 +/- 4.85 (3-25) years, and the mean follow-up period was 6.96 +/- 4.55 (1-23) years. Evaluation of the patients in relation to their fecal continence revealed that 35 (37.6%) had constipation, 22 (23.6%) had fecal soiling, and voluntary bowel movements were absent in 7 (7.5%). Fecal continence was evaluated using the Krickenbeck classification, and it was good in 74 (79.6%), fair in 12 (12.9%), and poor in 7 (7.5%). QOL evaluation of these cases showed markedly decreasing QOL as the cases changed from good to poor fecal continence. Urinary system pathology was detected in 35 (37.6%) of the cases with 22 (23.7%) having severe uropathology. We compared the 22 patients with severe uropathology and 71 cases without severe uropathology for QOL and found the ARM group with severe uropathology to have significantly lower physical QOL, psychosocial QOL, and total QOL values. Reviewing the patients by fecal continence and urinary pathologies together regarding QOL showed that patients with good fecal continence and no additional urinary abnormality had the best QOL. The QOL decreased considerably in both the group with a fecal incontinence problem but no additional urinary abnormality and the group with good fecal continence but serious additional urinary abnormality. The QOL was worst in patients with urinary pathology and fecal incontinence. DISCUSSION: Anorectal malformations constitute a wide spectrum of disease. Urinary anomalies and their complications significantly increase the morbidity in these children even after the correction of the ARM. In the evaluation of the published series, we noted that the main issue was fecal continence, and there was not enough data concerning the urinary system pathologies of the patients when they reach adult ages. Anorectal dysfunction has a negative effect on QOL in ARM patients, but is not life threatening. Such patients can lead normal life although the QOL is affected. However, vesicoureteral dysfunction can cause permanent damage in other organs. This damage may cause mortality depending on the level of the malformation. Evaluating the patients considering fecal continence and urinary system pathology together showed that nearly 10% of the ARM patients had serious problems affecting their long-term QOL related to fecal control, whereas nearly a fourth of the cases had additional anomalies of the urinary system that will affect the QOL despite all treatments used, as the development of pyelonephritis, hypertension, and end-stage renal disease should be expected in these patients. CONCLUSION: Urinary system anomalies in patients with ARM are at least as serious and complex as gastrointestinal system anomalies and create more problems than fecal incontinence during long-term follow-up.

Clinical experience in hypospadias: results of tubularized incised plate in 496 patients.

OBJECTIVES: To review the tubularized incised plate, a recently popularized technique, and provide outcomes. METHODS: From January 2000 to December 2006, 496 patients underwent the tubularized incised plate technique for hypospadias at our clinic. The patient age range was 6 months to 14 years. The postoperative follow-up time was 2 years (range 6 months to 3 years). The patients underwent the technique as described by Snodgrass, with some small technical modifications. The patients were hospitalized for 10 days postoperatively, with a urethral stent in place. RESULTS: Of the 496 patients, 48 experienced 53 complications. The most frequent complication was meatal stenosis (n = 27, 5%), followed by urethrocutaneous fistula (n = 25, 5%). Dehiscence was noted in 1 patient (0% of 496 patients and 2% of the 48 patients with complications). Initially, the fistula occurrence rate was 11% and 4% for all 496 and the 48 patients with complications, respectively, which had decreased to 3% and 8% in the most recent 3 years. During the study period, some technical modifications have applied, with a resulting decrease in the complication rates. Complications occurred in 48 patients (9%), of whom 25 required surgical repair (5% of 496 patients). CONCLUSIONS: The tubularized incised plate technique is a surgical method that can be applied to most hypospadias anomalies. Increasing clinical experience and minor additions to the technique have enhanced our success with this method.

Postnatal testicular regression mircopenis and microcephaly: conformation of a new syndrome?

Testicular regression may develop at various phases of the intrauterine period and the clinical findings vary depending on the timing of the intrauterine phase. On the other hand, postnatal regression of the testicles is rare and few cases have been reported in the literature. Our patient presented with undescended testicles, micropenis, flat scrotum and microcephaly. The patient's levels of basal luteinizing hormone (LH) were low/normal and follicle stimulating hormone (FSH) was high. No response was obtained in the human chorionic gonadotropin (HCG) stimulation test. The levels of inhibin B and anti Mullerian hormone (AMH) were found to be low. Penile growth response to intramuscular testosterone injections was 2.5 cm. Testicles were visualized bilaterally in inguinal canal by ultrasound examination initially but by 2 years of age no testicular tissue was observed during inguinal exploration. In conclusion we recognized postnatal testicular regression in our patient that had started in the intrauterine period and persisted into infancy. The genital system anomalies, microcephaly and motor retardation in our patient confirm the hypothesis of Parisi et al. of a novel condition of postnatal regression and micropenis.

From a branchial fistula to a branchiootorenal syndrome: a case report and review of the literature.

Branchial abnormalities constitute 32% to 45% of all neck pathologies in children. They may be a part of branchiootorenal (BOR) syndrome, which is characterized by branchial arch anomalies, preauricular pits, hearing impairment, and renal malformations. Typically, the management of a branchial fistula does not necessarily require an extensive diagnostic workup. However, in patients with a branchial fistula associated with external ear anomalies on physical examination and/or a history of hearing loss and a similar history and findings in other family members, an additional workup should be performed to eliminate the possibility of BOR syndrome. The aim of this report is to make pediatric surgeons aware of the BOR syndrome in patients presenting with branchial arch anomalies.

Is hernial sac removal necessary? Retrospective evaluation of eight patients with Morgagni hernia in 5 years.

Eight children with Morgagni hernia were operated between January 2000 and May 2005. Medical records of the patients were evaluated retrospectively. Ages of the patients were between 3.5 months and 9 years. The diaphragmatic defect was on the right in all patients except one. One patient had bilateral diapragmatic hernia. All of the patients were operated by abdominal approach. All patients had hernial sacs. During operation sac of hernia was everted to peritoneal space without removal and the defect was closed by using nonabsorbable material. There was no intraoperative complication. The patients were discharged on the sixth day in uneventful condition. There was no complication or recurrence during follow up. Excision of sac of hernia is recommended in majority. Most of the published studies favour the removal of hernial sac. In our practise, in the treatment of Morgagni hernia we did not remove the hernia sac during the last 5 years.
