Ovarian torsion. Management and ovarian prognosis: a report of 45 cases

BACKGROUND/PURPOSE Ovarian torsion in childhood and adolescence is a rare entity. Traditionally, treatment is oophorectomy. The aim of this study was to evaluate ovarian outcome and to propose a decision-making protocol for suspected ovarian torsion. METHODS Between January 1986 and December 2007, 45 ovarian torsion cases in 40 girls were operated on. In all the cases, when the ovary was preserved, patients were clinically and ultrasonographically followed up for several months. RESULTS Median age was 11 years. Median delay between the first symptoms and surgical procedure was 3 days. There was a statistical difference (P = .0003) between the mean of the largest diameter of twisted normal ovary and the mean of the largest diameter of twisted diseased ovary. Underlying pathology was benign in 22 cases and low-grade malignancy in 2 (one grade II immature teratoma and one steroid cell tumor). Conservative management was performed in 26 cases. At follow-up, 17 ovaries were follicular, 7 being black-bluish during surgery. CONCLUSIONS Conservative approach after detorsion of black-bluish ovaries is safe and effective in children. Although very unlikely, the fear of missing malignancy must incite to proceed with caution and can lead, when the size of the twisted ovary is greater than 75 mm, to prefer laparotomy to laparoscopy.

Ovarian germ cell tumors in children. Management, survival and ovarian prognosis. A report of 75 cases.

BACKGROUND/PURPOSE The aims of this study were to evaluate survival and ovarian prognosis in patients treated for ovarian germ cell tumor (OGCT) and to propose a decision-making protocol. METHODS Charts of girls operated on for OGCT from 1976 up to 2009 were reviewed retrospectively. Tumor characteristics were assessed by tumor markers, imaging, and pathology. RESULTS Charts were available in 71 children presenting 75 OGCT. Tumors were benign in 58 cases and malignant in 17 cases. The average of the largest diameter of benign OGCT was significantly lower than that of malignant OGCT (76.5 +/- 49 mm versus 169 +/- 54 mm, P < .0001). Ovarian-sparing tumorectomy was carried out in 27 benign OGCT; 23 (85%) preserved ovaries were follicular. Malignant OGCTs were managed according to the protocols of the French Society for Pediatric Oncology. Bilateral oophorectomy had to be performed in 2 children. One patient presented a recurrence and 1 died. CONCLUSIONS In our series, both benign and malignant OGCTs have a good prognosis. A 75-mm cutoff size is proposed as an important criterion to preoperatively differentiate between benign and malignant tumors. In benign OGCT, ovarian-sparing tumorectomy leads to preserve ovaries in approximately 85% of cases, and in malignant OGCT, high survival rate has been obtained.

Contribution to the study of the venous vasculature of the penis

The penile veins are thought to be responsible for some erectile disorders. The aim of this study was to describe the anatomy and function of these veins. The venous systems of 25 cadaveric penises were studied by various anatomic and histologic techniques. The superficial veins arising from the tegumentary layers drain into the superficial dorsal vein which in three-quarters of cases empties into the left great saphenous vein. The veins of the deep internal system, running below the deep fascia of the penis, emerge from the erectile bodies and can be divided into two systems, one anterosuperior and the other posteroinferior. The anterosuperior system comprises the veins of the glans which will form the deep dorsal vein the latter receives blood from the medial portion of the corpus spongiosum and from the free portion of the corpora cavernosum mainly via the circumflex veins. It ends in the pre-prostatic plexus. The posteroinferior system, issuing from the posterior portion of the erectile bodies, is composed of the bulbar, cavernous and crural veins which drain towards the pre-prostatic plexus and the internal pudendal veins. Anastomoses link the two networks, superficial and deep. Study of the structure of the veins of the deep system reveals the presence of muscular cushions, which we have shown to have adrenergic innervation. These findings are compared with those of the literature, which show variations which are mainly of number. The place of veins in the mechanism of erection is discussed.

Neonatal repair of cleft lip: a decision-making protocol

PURPOSE Treatment of clefts lip during the neonatal period remains a controversial subject. Those who are in favor of delayed closure argue a higher-risk general anesthesia when it was performed in neonatal period. The purpose of this study was to evaluate the complications and the feasibility of this surgery during the neonatal period. METHODS This was a retrospective study of 61 children with labial, labioalveolar, labio-alveolo-palatine, and labiopalatine clefts between May 2000 and November 2006. Each patients medical file and particularly his or her anesthesia file was used to record the principal demographic data, the results of the malformation workup, and preoperative complications. RESULTS Sixty-one newborns, 20 girls and 41 boys, aged 7.5 +/- 6.7 days were operated on. The mean weight on the day of surgery was 3190 +/- 454 g. Fifty-four children had a malformation workup (abdominal ultrasonography, spinal bone workup, transfontanelle ultrasonography, and cardiac ultrasonography). Thirteen associated malformations (21%) were thereby detected. There were no surgical complications. The anesthesiologists did not have any real intubation problems. In 4 cases, however, intubation was only possible after several laryngoscopies and changing the type of intubation shaft. There were no major complications. However, one child did present a preoperative complication. It was an episode of desaturation with bradycardia that was quickly resolved without further consequences in a child with a ventricular septal defect and an auricular septal defect. CONCLUSIONS We think that neonatal lip closure should continue to be performed. It is essential for the psychological status of the parents. We have not found any studies in the literature that reported an anesthesia risk that was greater in the neonatal period than at 3 months in patients without risk of complications.

Mechanical occlusion of the inferior vena cava: An early complication after repair of pectus excavatum using the Nuss procedure

The Nuss procedure is the most widely used surgical procedure to correct pectus excavatum. Although it is a minimally invasive approach, a number of major early complications, such as heart perforation, have been reported. We describe a 15-year-old boy in whom acute occlusion of the inferior vena cava developed after a Nuss repair. The diagnosis was confirmed by emergency postoperative CT examination, and treatment consisted of immediate removal of the Nuss bar.

Conservative management of blunt pancreatic trauma in children: a single center experience.

INTRODUCTION Blunt trauma of the pancreas represents a significant part of abdomen trauma in children with an incidence estimated at around 10%. If the conservative management is widely accepted concerning the stages I and II, it remains controversial concerning stages III and IV. The aim of our study was to perform a descriptive analysis of the nonoperative management, with a focus on the occurrence of pseudocysts. MATERIALS AND METHODS The charts of the patients treated in our center for pancreatic trauma from 1990 to 2010 have been reviewed. It was defined by an initial lipase greater than three times the norm and an abnormal computed tomography scan. RESULTS A total of 36 patients were included, with 26 boys (72%) and 10 girls (28%) with an average age of 8.7 years. The trauma was isolated in 13 cases (36.1%) and in 23 cases, there were other associated lesions (mainly liver [n = 9] and spleen [n = 5]). Pancreatic injuries were graded as follows: I (n = 21), II (n = 2), III (n = 7), and IV (n = 6). Pseudocysts occurred in 11 patients (30.5%) mainly in grades III (n = 3) and IV (n = 7), with an average delay of 17 days. Initial management of pseudocysts was conservative in six patients (54.6%), whereas five patients required mini-invasive procedures. CONCLUSION Nonoperative management remains a safe way to treat pancreatic injuries despite an average 30% rate of pseudocyst (PC) appearance. It allows a reduction in the number of children who required procedures to less than half of the patients where PC occurred. Furthermore, these procedures were exclusively mini-invasive.

The surgical management and outcome of congenital mediastinal malformations

We reviewed our institutional experience with congenital mediastinal masses and compared the postnatal management and outcome of patients with or without prenatal diagnosis. Between January 1997 and August 2011, 24 patients underwent surgical procedures for congenital mediastinal mass. For eight patients, the mass was detected by prenatal ultrasonography at 27 weeks of gestation (range 22-35). Postnatal management consisted in open surgery for seven patients at a mean age of 9 months (range 1 day-20 months) and sclerotherapy for one lymphangioma at 5 months of life. Sixteen patients had postnatal diagnosis at 137 months (±194) of median age. Eight bronchogenic cysts, seven bronchopulmonary foregut malformations, five teratomas, three lymphangiomas and one haemangioma were operated on. The median age at resection was 28 months (1 day-15 years). There were four emergency procedures and no surgical mortality. The median follow-up was 45 months (3-144). The duration of mechanical ventilation and hospital stay was, respectively, 4.6 h and 7.5 days for antenatal patients and 24.3 h and 14.3 days for postnatal diagnosed patients. Prenatal diagnosis allows early management of congenital mediastinal malformations. Early resection can be performed prior to the occurrence of symptoms ∼1 year of life and is associated with an excellent outcome and less morbidity.

Pathologie urgente des organes génitaux externes chez le nourrisson

Resume C’est un motif de consultation frequent en cabinet mais aussi dans les services d’urgence. L’urgence, en dehors de la hernie etranglee et de la torsion du cordon spermatique, n’est que tres relative. Toutefois, comme frequemment chez l’enfant, cette pathologie s’accompagne de beaucoup d’angoisse chez les familles.

Necrotizing fasciitis due to Pseudomonas aeruginosa in immuno-compromised children.

To the Editor: First described as streptococcus gangrene by Meleney [1], necrotizing fasciitis (NF) remains a rare entity in pediatric practice with an incidence of 0.08 per 100,000/year and is still associated with a poor outcome despite aggressive surgical treatment [2]. Most reported pediatric cases are caused by group A beta-hemolytic streptococci. However, NF has been reported as being multimicrobial in about 70% of adult cases [3]. Monomicrobial NF caused by Pseudomonas aeruginosa has been rarely reported with only 12 cases reported in the literature [4]. This pathogen is mostly involved in multimicrobial infections with an average frequency of 10% in cervical NF and in Fournier’s gangrene [5]. Only five pediatric cases have been described (Supplemental Table I). Four presented with leukemia (3 ALL and 1 AML) as a contribution and chemotherapy as an initiating factor.

Non-contrast-enhanced MR angiography using time-spin labelling inversion pulse technique for detecting crossing renal vessels in children with symptomatic ureteropelvic junction obstruction: comparison with surgical findings.

ObjectivesInvestigate the feasibility and evaluate the accuracy of non-contrast-enhanced MR angiography (NC-MRA) using time-spin labelling inversion pulse (time-SLIP)to identify crossing renal vessels (CRVs) in children requiring surgical treatment of ureteropelvic junction (UPJ) obstructionand compare to laparoscopic findings.Materials and methodsNineteen children ranging from 6 to 16 years of age underwent NC-MRA using the time-SLIP technique before surgery. Two independent readers analysed the MRA images. Number of renal arteries and presence or absence of CRVs were identified and compared with surgicalfindings. Image quality was assessed, as well as the presence of CRVs and measurement of renal pelvis diameter. Intra and inter-reader agreement was calculated using Cohen’s kappa coefficient and Bland–Altman plots.ResultsThe overall image quality was fair or good in 88% of cases. NC-MRA demonstrated CRVs at the level of the obstruction in 10 children and no CRV in 9 children. All were confirmed intra-operatively except in one of the nine children. Sensitivity, specificity, NPV, PPV for predicting CRVs were 92%, 100%, 100% and 87.5%, respectively, for both readers.ConclusionNC-MRA is a good alternative to contrast-enhanced MRA and CT scanning for identifying CRVs in children with symptomatic UPJ.Key points• Time-SLIP technique offers acceptable imaging quality for identifying crossing renal vessel.• Time-SLIP technique is easy to apply to the renal MRA examination.• Time-SLIP technique is an alternative to contrast-enhanced MRA and CT scanning.
