MRI diagnosis of jejunal haematoma, mimicking a mass lesion

We present a case of jejunal haematoma just distal to the origin of treitz ligament. The magnetic resonance imaging (MRI) appearances of this entity have not been widely reported. MR imaging was used for differential diagnosis between the intestinal mass and haematoma because of the unreliable history and unclear sonography findings. MRI clearly demonstrated jejunal haematoma and obstructed intestinal lumen. © 2005 Elsevier Ireland Ltd. All rights reserved

Pediatric mesenteric panniculitis: three cases and a review of the literature

Mesenteric panniculitis is an inflammatory and fibrotic process in the mesenteric adipose tissue with unknown etiology. It is rarely seen in general, particularly in children. Etiology is unknown, and pathophysiology is not clear. Factors that trigger the disease are malignancy, tuberculosis, trauma, medications and past surgical interventions. There is no pediatric case series in the literature except single case reports. This paper consists of 3 cases: The first case is a 5-month-old girl, the youngest patient in the literature, who was referred to a pediatric surgeon with vomiting and abdominal distention. She had diffused intraabdominal fluid and mesenteric panniculitis documented by perioperative biopsy. The second case had acute abdominal pain with perforated appendicitis, who eventually had mesenteric panniculitis in the evaluation of the pathological specimen. The last case had a diagnosis of polyarticular juvenile idiopathic arthritis (JIA), successfully treated with etanercept, and has been in remission for 2 years. Interestingly, in one of her routine visits, she had pallor, anemia and renal failure. Bilateral hydronephrosis was detected. Magnetic resonance imaging (MRI) of the abdomen revealed retroperitoneal fibrosis, and mesenteric panniculitis was the histopathological diagnosis

Diagnostic failures in ovarian torsion during childhood: The effect of ovarian cyst size on the diagnostic accuracy of Doppler ultrasonography

Purpose: To determine the diagnostic accuracy of Doppler ultrasonography (US) in pediatric ovarian torsion (OT) and the effect of ovarian cyst size on the effectiveness of Doppler US in pediatric OT

Nuss procedure: Technical modifications to ease bending of the support bar and lateral stabilizer placement

Background: Modifications defined to ease bending of the support bar and lateral stabilizer placement during minimal invasive repair of pectus excavatum (MIRPE) have not been reported. We herein report our experience with MIRPE including several technical modifications. Methods: A total of 87 patients who underwent MIRPE were evaluated retrospectively. Technical modifications are (1) a template drawn preoperatively according to the anthropometric measurements, (2) more laterally placed thoracal incisions, (3) single existing incision for multiple support bars, (4) to secure lateral stabilizers to support bar in inverted position. Results: The mean patient age was 11.2 ± 3.8 years. The mean operating time was 63.7 ± 18.7 min. The mean Haller index was 5.4 ± 2.1. Eight patients necessitated two support bars. The support bars were removed in 69 patients after the completion of treatment. Support bars were left in place 26.8 ± 4.3 months. Final chest contours of the 56 patients were evaluated as 12 months passed after support bar removal and excellent repair results were determined in 84.2%. Conclusion: Preoperative bending of the support bar according to anthropometric measurements and fixation of the lateral stabilizers to the support bar in inverted position facilitates bar shaping and lateral stabilizer placement

Urinary continence after high urogenital sinus repair conducted with posterior prone approach: electromyography-uroflowmetric assessment

Purpose We aimed to present the results of urinary continence assessment objectively with electromyography (EMG)-uroflowmetry after high urogenital sinus (HUGS) repair with posterior prone approach without division of rectum. Methods The records of patients who underwent HUGS repair via posterior prone approach between January 2005 and July 2018 were reviewed retrospectively. Incontinence, dysuria, hesitation, and straining during urination were evaluated during the clinical follow-up. Dysfunctional voiding scoring system was used as a questionnaire. Patients were re-evaluated with EMG-uroflowmetry in terms of voiding volume and pattern, voiding time, maximum flow rate, average flow rate, maximum flow time, and post-voiding residual volume. Results Seven patients with HUGS were treated with a posterior prone approach. The median age of the patients was 18 months (8-21 months). The median UGS length was 4.4 cm (3.6-5.5 cm), urethral length was 1.1 cm (1.0-1.5 cm), and vaginal length was 4.9 cm (4.1-5.1 cm). No urination or defecation problems were described by the patients or their parents. When the results of the dysfunctional voiding scoring systems questionnaire were analyzed, results scored 7 (range 5-8). EMG-uroflowmetric test graphics of the patients showed normal flow curves without plateau, intermittency or irregularity. Pelvic EMG assessment was normal in all patients. Conclusion EMG-uroflowmetry has shown objectively that urinary continence and normal voiding pattern are preserved after HUGS repair with posterior prone approach without division of rectum

Distribution of interstitial cells of Cajal in the bladders of fetal rats with retinoic acid induced myelomeningocele

WOS: 000388501500012PubMed ID: 27909623Objective: Myelomeningocele (MMC) is one of the most common reason of neurogenic bladder dysfunction in children. Although neurogenic bladder dysfunction occurrence is related with bladder innervation, also there are some changes seen in the smooth muscle and neural cells of the bladder. Interstitial cells of Cajal (ICC) are the pacemaker cells found in organs with peristaltic activity. Although it has been shown that ICC are diminished in the rat urinary bladder with traumatic spinal cord injury, there is no data about ICC in fetal rat bladders with MMC. This study has been conducted to investigate the ICC in the bladders of fetal rats with retinoic acid induced MMC. Materials and methods: Time dated pregnant Wistar albino rats were divided into 3 groups. In MMC group, dams were fed with gavage solution containing 60 mg/kg all-trans retinoic acid dissolved in olive oil on 10. embryologic day. Sham group animals were fed only olive oil. Control group dams were fed with standard rat chow. Fetuses were delivered by cesarean section and harvested on 22. embryologic day. MMC was identified by observing MMC sacs at the back of the fetuses. Distribution of ICCs were evaluated using immunohistochemical staining. Results: ICCs were found in all groups, which have the same morphological features that had been described earlier in the gastrointestinal tract and the bladder. The density of the ICC in the MMC group was found to be significantly decreased when compared with the control and the sham groups (p<0.05). Conclusion: The density of the ICC in the urinary bladder decreased in the neurogenic bladder developed in MMC

Ultrasound‐guided

Purpose To detect false-positive reduction results after ultrasound (US)-guided hydrostatic intussusception reduction, we have incorporated water-soluble contrast material to the enema fluid and confirmed the reduction with a single abdominal radiograph. We present the results of the combined imaging method for the reduction of intussusception in children

Inflammatory Changes Induced by Dextranomer/Hyaluronic Acid Injection into the Several Different Wall Layers of Ureterovesical Junction

Objective: Endoscopic subureteric injection (ESI) is a minimally invasive and effective method for the treatment of vesicoureteral reflux. Ureterovesical junction (UVJ) obstruction after subureteric dextranomer/hyaluronic acid (Dx/HA) injection has been reported in the literature. Inflammatory changes in the several different wall layers of the UVJ after injection of Dx/HA have not been investigated before. The aim of this study is to evaluate the inflammatory response induced by Dx/HA in the several different wall layers of UVJ in an experimental rat model
