Abstract Objective To assess the incidence and the risk factors implicated in acute appendicitis in preschoolers in our region. Methods Over a 7-year period, 352 children underwent appendectomy for suspected acute appendicitis. Of these, data for 23 children were excluded because no inflammation of the appendix was found on subsequent histology. Of the remaining 329, 82 were ≤ 5 years old (i.e., preschool children) and 247 were 5-14 years old. These two groups of children were further divided according to their religion into Muslims and Christian Orthodox: 43 of the children aged ≤ 5 years were Muslims and 39 were Christian Orthodox. A household questionnaire was designed to collect data concerning age, gender, type of residence area, living conditions, vegetable consumption, and family history of surgery for acute appendicitis as preschool children. The removed appendices were also assessed histologically for the amount of lymphoid tissue. Results Acute appendicitis of preschoolers developed more frequently in Muslims (39.4%) than in Christians (17.7%; p < 0.001). The lack of inside toilet facilities at home, overcrowded living conditions, living in rural areas, and the amount of appendix lymphoid tissue were significantly more frequent among the Muslim preschool children (p < 0.05), while there were no statistically significant differences between Muslim and Christian children with regard to gender, the family history of acute appendicitis, or the vegetable consumption (p > 0.05). Conclusions In our region, the percentage of preschool-aged Muslim children with acute appendicitis was remarkably high. One possible explanation for this finding could be the higher amount of lymphoid tissue in the wall of the appendix in Muslim preschool children together with their low standard of hygiene.

Abstract Introduction Although Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract and modern imaging techniques are available, its diagnosis remains problematic. Case presentation A technetium-99 scan was performed in an 18-year-old man with abdominal pain, vomiting and rectal bleeding to confirm the presence of a Meckel's diverticulum which was not diagnosed laparoscopically elsewhere. The technetium-99 scan was positive and a diagnostic laparoscopy was re-performed which revealed a Meckel's diverticulum that was subsequently resected. Conclusion We suggest that a technetium-99m scan should be performed before laparoscopy in children and adolescents with suspected Meckel's diverticulum. A positive technetium-99m scan may significantly contribute to the laparoscopic definitive diagnosis and treatment of a bleeding Meckel's diverticulum. However, diagnostic laparoscopy should only be performed by experienced surgeons.

Abstract Background Hemangiomas are the most common type of congenital anomaly in childhood. Although many resolve spontaneously, intervention is required when their growth could damage vital adjacent structures. Various therapeutic approaches to childhood hemangiomas with different types of laser have been described previously. The objective of this study was to determine whether the cooling of the epidermis during irradiation of hemangiomas with a Nd:YAG laser prevents thermal damage and decreases the number of sessions required to treat these lesions. Methods Between 1993 and 2001, 110 patients aged 3 months to 4 years, with cutaneous hemangiomas were treated with a Nd:YAG laser. The lesion was cooled with ice prior to, during, and after the irradiation. During each session the laser beam passed through the pieces of ice. The laser power was between 35–45 W with a pulse length of 2–10 seconds. Results After 6 months of follow-up, from the first session of laser treatment, total resolution was obtained in 72 (65.5%) patients. A second or third session followed in 30 out of 38 patients in which, the initial results were good, moderate, or poor. The parents of the remaining eight children refused this second session and these patients excluded from the study Complications were seen in nine (8.8%) patients. One patient had postoperative bleeding which stopped spontaneously, while atrophic scars occurred in six (5.8%) patients, and hypertrophic scars in two (1.9%) patients. Conclusions Nd:YAG laser irradiation in conjunction with ice protection of the epidermis produces good cosmetic results for the treatment of cutaneous hemangiomas in children, and decreases the number of sessions for treatment of these lesions.

Objectives: The aim of our study was to elucidate the current pattern of acute poisoning among children admitted to a regional University Hospital in the prefecture of Evros in Northern Greece. We also compared the obtained findings with those of two previous studies performed in the same region.Methods: Demographic and clinical data, management, and outcome of children with acute poisoning were recorded in our region, during the past 5-years (2005-2009, period C) and compared to similar studies carried out in the periods 1985-1989 (period A) and 1995-1999 (period B).Results: Comparison between the three periods showed that in period Athe lower incidence of children's acute poisoning (CAP) was observed. Also this revealed a 20%-reduction in the frequency of poisoning over the past 5-years (period C) compared to period B (p = 0.219), a significant increase in tobacco intoxication over the years (in the order A-C; p < 0.001 for comparisons of periods A and B, and periods B and C), while poisoning from insecticides-pesticides decreased (p < 0.001). The incidence of poisoning via salicylates significantly reduced from 9.7% in period A to 6.2% in period B, and further to 4.7% in period C (p = 0.016), whereas during the same periods poisoning via paracetamol increased from 2.3% to 5.1% and then to 10.4%, respectively (p < 0.001). Atrend toward a higher incidence of suicide attempt via poisoning was found during the three periods (from 3.0% in period A to 4.7% and 6.6%, in periods B and C, respectively; p = 0.049).Conclusions: The frequency of acute poisoning among children has decreased over the past 5 years. The incidences of poisoning via paracetamol and tobacco, and attempted suicide have increased in recent years. Targeted and continuous educational preventive programs are mandatory.

Objective: To present a prospectively studied series of patients who underwent second-look flexible nephroscopy combined with holmium:yttrium-aluminum-garnet (Ho:YAG) laser lithotripsy under local anesthesia for residual stone removal after percutaneous nephrolithotomy (PCNL)., Materials and Methods: Thirty consecutive eligible patients who underwent a PCNL procedure in the previous 48-96 hours were included. The inclusion criteria were the following: (1) 1 or 2 residual stones 0.8-1.5 cm in diameter and (2) age >18 years. Approximately 15 mL of a 2% solution of lidocaine hydrochloride was injected through the nephrostomy tube, which was then clamped for 15 minutes. Flexible nephroscopy was combined with Ho:YAG laser lithotripsy set at 0.8 Joules and 8 Hz. Patients were asked to rate their pain intensity using the numeric rating scale (NRS)., Results: There were 14 (46.7%) men and 16 (53.3%) women in the study, with a mean age of 45.2 ± 17.5 years. Twenty-one (70%) patients had 1 stone and 9 (30%) had 2 stones needing fragmentation. Twenty-eight (93.3%) patients successfully underwent the procedure under local anesthesia. The mean NRS value was 1.39 ± 1.08 (range 0-5). For the entire group, there was a statistically significant difference between those patients with 1 stone vs 2 stones needing fragmentation (NRS scores of 1.1 ± 0.77 vs 2.1 ± 1.36, respectively, P = .033). Operative time >30 minutes was associated with higher NRS score. The stone-free rate under local anesthesia was 86.7%., Conclusion: For patients with a minimal to moderate residual stone burden after PCNL, second-look flexible nephroscopy can be combined with Ho:YAG laser lithotripsy using only local anesthesia., (Copyright © 2016 Elsevier Inc.

We present a 7-year-old boy with recurrent thrombocytopenia after primary laparoscopic splenectomy for immune thrombocytopenia (ITP). Imaging modalities (ultrasound, computed tomography scan, and scintigraphy) revealed two accessory spleens while the subsequent second laparoscopy revealed 11, which were successfully removed. The relevant medical literature is reviewed, and the value of laparoscopy for chronic ITP is highlighted.

Background: Testicular torsion is an acute urologic emergency occurring in male newborns, children or adolescents. Prolonged ischemia for more than six hours can lead to irreversible testicular damage. Surgical detorsion allows reperfusion and is the only treatment currently available. The aim of this study was to evaluate the antioxidant effect of apigenin (APG) on the testicular ischemia-reperfusion (I/R) injury., Methods: Forty-two Wistar rats were randomly divided into five groups. Sham group underwent operation of the left testis. In the torsion-detorsion groups C15 and C120, the left testis was rotated 1080(o) for three hours. The treatment groups Ap15 and Ap120 received the same surgical procedure as groups C15 and C120, but APG was administered intravenously at the same time of detorsion via the right femoral vein. Left orchiectomy was performed 15 min after detorsion at groups C15 and Ap15, and at 120 min at groups C120 and Ap120 for histopathologic and immunohistochemical evaluation., Results: In I/R-untreated groups C15 and C120, there was a moderate to severe distortion of the tubules with lesions that varied between grades III and IV according to histopathological finding. In APG-treated groups Ap15 and Ap120, most of the lesions showed injuries of grades II and III with mild and moderate histopathological features. In Terminal deoxynucleotide transferase dUTP Nick End Labeling (Tunel) assay, APG-treated animals showed a statistically significantly decreased number of apoptotic cells compared to groups C15 and C120., Conclusion: Intravenous administration of APG seems to have a protective effect on testicular ischemia-reperfusion injury after testicular torsion and detorsion.

Importance: No studies have systematically examined the accuracy of clinical, laboratory, and imaging variables in detecting renal scarring in children and adolescents with a first urinary tract infection., Objectives: To identify independent prognostic factors for the development of renal scarring and to combine these factors in prediction models that could be useful in clinical practice., Data Sources: MEDLINE and EMBASE., Study Selection: We included patients aged 0 to 18 years with a first urinary tract infection who underwent follow-up renal scanning with technetium Tc 99m succimer at least 5 months later., Data Extraction and Synthesis: We pooled individual patient data from 9 cohort studies., Main Outcomes and Measures: We examined the association between predictor variables assessed at the time of the first urinary tract infection and the development of renal scarring. Renal scarring was defined by the presence of photopenia on the renal scan. We assessed the following 3 models: clinical (demographic information, fever, and etiologic organism) and ultrasonographic findings (model 1); model 1 plus serum levels of inflammatory markers (model 2); and model 2 plus voiding cystourethrogram findings (model 3)., Results: Of the 1280 included participants, 199 (15.5%) had renal scarring. A temperature of at least 39°C, an etiologic organism other than Escherichia coli, an abnormal ultrasonographic finding, polymorphonuclear cell count of greater than 60%, C-reactive protein level of greater than 40 mg/L, and presence of vesicoureteral reflux were all associated with the development of renal scars (P ≤ .01 for all). Although the presence of grade IV or V vesicoureteral reflux was the strongest predictor of renal scarring, this degree of reflux was present in only 4.1% of patients. The overall predictive ability of model 1 with 3 variables (temperature, ultrasonographic findings, and etiologic organism) was only 3% to 5% less than the predictive ability of models requiring a blood draw and/or a voiding cystourethrogram. Patients with a model 1 score of 2 or more (21.7% of the sample) represent a particularly high-risk group in whom the risk for renal scarring was 30.7%. At this cutoff, model 1 identified 44.9% of patients with eventual renal scarring., Conclusions and Relevance: Children and adolescents with an abnormal renal ultrasonographic finding or with a combination of high fever (≥39°C) and an etiologic organism other than E coli are at high risk for the development of renal scarring.

Objective: To prospectively evaluate the efficacy and safety of a perimeatal-based penile skin flap for neourethral coverage after repair of distal hypospadias with tubularized incised plate urethroplasty (TIPU)., Methods: In 12 New Zealand white rabbits a ventral urethral defect was created and reconstruction was accomplished with continuous suture. An epithelialized defect-based flap was harvested from the penile skin to cover the repaired defect. The animals were euthanized on the 28th postoperative day and their penises were processed for microscopic examination. In 32 children with distal hypospadias a TIPU was performed. A penile skin flap was created immediately below the distal end of the neourethra and used to cover the urethroplasty., Results: Histological examinations revealed complete restoration of continuity of the stratified squamous epithelium without evidence of inflammation or fistula formation with full consistency with the underlying papillary reticular and corium. There were no cases of fistula formation. One patient developed meatal stenosis. All patients had a satisfactory cosmetic appearance and excellent functional results., Conclusion: The formation of a perimeatal-based skin flap is a simple and safe method of providing additional cover for the constructed neourethra after TIPU, minimizing the fistula rate., (Copyright © 2014 Journal of Pediatric Urology Company.

Crohn's disease (CD) can occur anywhere in the gastrointestinal tract from the mouth to the anus and sometimes it presents in a nonspecific manner. Herein we describe a case of local peritonitis as the first manifestation of CD in an 11-year-old girl, and the subsequent method of treatment.

Purpose: We studied the late angiogenic activity of free grafts and a pedicle flap in a rabbit urethroplasty model to determine whether angiogenic activity plays a role in late outcomes of urethral reconstruction in rabbits., Methods: Twenty-eight rabbits were randomly divided into five groups according to the method used to bridge a urethral defect as an onlay patch: Control, simple closure of urethral defect (Group O1); free penile skin graft (FPSG, Group A1); buccal mucosal graft (BuMG, Group B1); bladder mucosal graft (BlMG, Group C1); and pedicle penile skin flap (PPSF, Group D1). Angiogenic activity of the patch on postoperative day 84 was assessed by immunohistochemistry., Results: The angiogenic activity in Groups O1, A1, B1, C1, and D1 was 23.33 ± 4.92 (means ± SD), 42.89 ± 6.52, 55.78 ± 3.46, 53.61 ± 6.17, and 24.11 ± 9.07 vessels per optical field, respectively. There were statistically significant differences (p < .001) between Group O1 and A1 B1, C1, Group A1 and B1, C1, D1, Groups B1 and D1 and Groups C1 and D1, but not between Groups O1 and D1 (p = 1.000) and Groups B1 and C1 (p = .872). The long-term angiogenic activity of all the groups was significantly lower (p < .001) than in the corresponding early groups., Conclusions: Although the angiogenic activity of all the groups decreased in the late assessment, the buccal mucosal graft continued to exhibit elevated angiogenesis above bladder or skin (free or pedicle) graft. Therefore, buccal mucosal patch graft might be preferable because of its easier harvesting.

Background: Urinary tract infections (UTIs) are encountered frequently in children, and their early diagnosis and treatment are important. This study evaluates the diagnostic value of serum concentrations of lipopolysaccharide-binding protein (LBP), an acute-phase protein, in children with febrile UTI and compares it to those of the total white blood cell count (WBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), procalcitonin (PCT), and interleukin-6 (IL-6)., Methods: The study population comprised 77 consecutive patients with a first-episode febrile UTI (33 boys) with a median age of 11 months [interquartile range (IQR), 5.5-33 months], 21 healthy controls (11 boys) with a median age of 10 months (IQR, 5-20.5 months) and 58 febrile controls with a fever due to other causes (28 boys) with a median age of 12.5 months (IQR, 7-30 months). LBP, IL-6, PCT, and CRP were measured for both patients and control groups., Results: The serum levels of LBP (p  <  0.001), CRP (p  <  0.001), PCT (p  =  0.001), IL-6 (p  =  0.002), ESR (p  =  0.020), and WBC (p  <  0.001) were higher in patients with febrile UTI than in the healthy and febrile control groups. The LPB cut-off value for best sensitivity and specificity in patients with febrile UTI was >43.23 mg/l. Furthermore, the area under the receiver operating characteristic curve was significantly greater for LBP than for CRP (p  =  0.014), PCT (p  <  0.001), ESR (p  <  0.001), WBC (p  =  0.002) and IL-6 (p  =  0.006)., Conclusions: The results of this study suggest that the serum LBP concentration constitutes a reliable biologic marker for the diagnosis of a febrile UTI in children.

Introduction: The aim of this study was to investigate the expression of vascular endothelial growth factor (VEGF) in pedicle penile skin flaps (PPSFs) used for urethral reconstruction in rabbits and the effect of exogenous VEGF on the angiogenesis process in the PPSFs., Methods: We randomly divided 28 male New Zealand rabbits into two sets of animals. A ventral urethral defect was created in all animals. In the first set of animals (first experiment, n = 10), a PPSF was used for the repair and VEGF expression in the flap was estimated on days 1, 2, 3, 5, and 7 postoperatively. The second set of animals (second experiment, n = 18) included three groups: control, untreated, and VEGF groups. In control group (n = 6), the defect was repaired by simple closure. In untreated (n = 6) and VEGF (n = 6) groups, a PPSF was used for the reconstruction. In VEGF group, exogenous VEGF was injected subdermally on the postoperative day corresponding to the peak endogenous VEGF expression (first experiment results). The animals were sacrificed on the 21st postoperative day and the angiogenic activity was assessed. A p < 0.05 was considered statistically significant., Results: The highest expression of endogenous VEGF in PPSFs was noted on postoperative day 3. Angiogenesis in control, untreated, and VEGF groups was 23.06 ± 4.1, 30.00 ± 6.9, and 34.7 ± 6.9 (mean values ± standard deviation) vessels per optical field, respectively. There were statistically significant differences between control-untreated groups (p = 0.04) and untreated-VEGF groups (p < 0.0001), and indicative difference between untreated and VEGF groups (p = 0.064)., Conclusions: VEGF is expressed in PPSFs, used for urethral reconstruction in rabbits. Flap angiogenesis is much higher than angiogenesis in simple wound closure. VEGF injection on postoperative day 3 seems to enhance angiogenesis in flaps., (Georg Thieme Verlag KG Stuttgart · New York.)

A 3 years old boy with a history of surgery for orchidopexy was admitted to our hospital with fever and abdominal pain. Clinical examination and laboratory investigations revealed urinary tract infection with renal involvement. Ultrasonography demonstrated a solitary left kidney and raised the suspicion of a fusion anomaly. Voiding cystography disclosed grade III vesicoureteral reflux and technetium-99m dimercaptosuccinic acid scintigraphy revealed right to left crossed renal ectopia with fusion (L-shaped kidney). The patient is undergoing standard follow-up for the early detection of possible renal complications. In conclusion, L-shaped kidney is a rare entity and the (99m)Tc-DMSA scintigraphy played an important role on timely diagnosis.
