RESUMO
OBJECTIVES: The aim of our study was to analyze the epidemiological characteristics for suicide methods and factors over a 12-year period among child suicides in Northern Tunisia and to compare juvenile and adolescent suicides. STUDY DESIGN: This is a cross-sectional study. METHODS: We included all child and adolescent suicide cases that took place in the North of Tunisia over a 12 year period (2005-2016). Data were collected from medical records and judicial inquiries and were classified into three sections: sociodemographic data, the circumstances of suicide, and the autopsy findings. Data were then compared between the 'juvenile suicide group' and 'the adolescent suicide group', according to the WHO definition. RESULTS: Casualties were equally males and females, mostly adolescents (74.5%), aged 15 years old on average. Hanging was the most frequent suicidal method. A peak of frequency was observed in 2014. CONCLUSION: Our results suggested to focus, among other preventive measures, on the role of media coverage of child suicides.

BACKGROUND: Metanephric adenoma is a rare benign renal tumor of the kidney, uncommonly observed in children. It is often misdiagnosed preoperatively as a malignant neoplasm, leading to an unnecessary nephrectomy. The challenge is to make the right diagnosis preoperatively and therefore manage it with conservative surgery. We report a case of a child with metanephric adenoma who underwent nephron-sparing surgery. CASE PRESENTATION: A renal tumor was discovered fortuitously in an 18-month-old Caucasian girl with several congenital malformations. Investigations showed a 28 × 27 × 27 mm left renal mass centrally located, well defined, nonvascularized, with no calcifications and which compressed the adjacent renal tissue. Furthermore, there were no signs of metastasis. The decision of a multidisciplinary meeting was to perform a computed tomography (CT)-scan-guided biopsy. Histologic examination concluded it was a metanephric adenoma. We performed a left open partial nephrectomy via a flank retroperitoneal incision. The final histopathological examination confirmed the diagnosis. The postoperative course was uneventful. CONCLUSION: Preoperative diagnosis of metanephric adenoma is challenging. Because of the high probability of unnecessary radical nephrectomy, preoperative biopsy can be safe and determining to guide a more conservative approach so nephron-sparing surgery can be performed.

The cardiac location of the echinococcosis is rare. It is associated with complications potentially severe. Indeed, the break inside the cardiac chambers with pulmonary embolism is the inevitable complication of the echinococcosis of the right heart. Between January 1992 and January 2006, five patients were operated in the department of cardiac surgery of Sousse (Tunisia) for an emboligenous hydatid cyst of the right heart. The average age is of 30 years with extremes from 18 to 65 years. The cardio-pulmonary bypass is the technique of choice. We regretted a single death in immediate postoperative period. All the patients were controlled with an average recession of 36 months. A single late death was noticed. No recurrence was observed.

BACKGROUND: Spontaneous perforation of the bile duct (SPBD) is a rare disease in infancy. The pathogenesis, diagnostic modalities and treatment options for this condition are reviewed and discussed. METHODS: The authors report 2 new observations of SPBD in 2 male newborns aged respectively 27 and 21 days. RESULTS: The 2 newborns presented with cholestatic jaundice. Abdominal sonography showed an extrahepatic mass. Exploratory laparotomy revealed that the perforation was located in the cystic duct in the first case and in the common bile duct (CBD) in the second. The site of perforation was repaired and both patients underwent simple external biliary drainage. The postoperative course was uneventful for both patients with follow-up ranging from 2 to 4 years. CONCLUSIONS: SPBD is a rare, but important cause of surgical jaundice in infants. The pathogenesis of SPBD is unknown and multifactorial and diagnosis is often problematic. Surgical management is always required and a conservative approach is usually recommended. The prognosis is good with early surgical management.

OBJECTIVE: Intussusception owing to pathologic lead points is a challenging condition for pediatric surgeons. The aim of this study was to review the particularities of clinical presentation, the place of morphologic investigation in depicting the presence of an organic lesion and the management of secondary intussusception. PATIENTS AND METHODS: The authors report a series of 27 patients treated from 1986 to 2004, for secondary intussusception. RESULTS: Nineteen boys and 8 girls, aged from 45 days to 11 years (mean age: 40 months) presented with secondary intussusception: Meckel's diverticulum (13 cases); lymphoma (8 cases); intestinal duplication (3 cases); heterotopic pancreas (2 cases); intestinal polyp (1 case). All patients were operated upon after failure of hydrostatic reduction. An intestinal resection with an end to end anastomosis was done for 26 patients. The biopsy of a large abdominal mass after an easy reduction of the intussusception was performed in 1 case. Chemotherapy was started at the sixth postoperative day for the 8 children having lymphoma. Two of them died during therapy. For the 25 others, the postoperative course was uneventful with a mean follow-up of 4 years. COMMENTARY: The improvement of the management and the prognosis of secondary intussusception requires an early diagnosis. Morphologic examination must not be limited to the diagnostic of intussusception but must aim at searching a lead point. The reduction of this particular form is based exclusively on surgery.

Ureterocele is a rare urologic disorder characterized by pseudocystic dilatation of the terminal submucosal ureter. Most cases of ureteroceles are associated with complete ureteral duplicity and ureterohydronephrosis, whereas ureteroceles on simplex ureters are rarer. The authors report two cases of bilateral ureteroceles on simplex ureters diagnosed prenatally at 30 and 32weeks gestation. Fetal ultrasound had revealed bilateral ureterohydronephrosis. The delivery was made at term and renal function was normal at birth. Radiological and isotopic studies of the urinary tract confirmed the diagnosis of bilateral ureteroceles on simplex ureters that were obstructive in one case and not obstructive in the other case. Both cases had urinary antiseptic treatment and neither had urinary infection. Endoscopic puncture with electrocoagulation of ureteroceles was performed at 8 and 14months of age, respectively, with a simple postoperative course. Prenatal diagnosis of ureteroceles is essential to plan early multidisciplinary care to avoid long-term renal consequences.

BACKGROUND: Morgagni or retrosternal hernia is a rare entity. It's representing almost 4% of all types of congenital diaphragmatic hernias in children. POPULATION AND METHODS: The data concerning 7 infants with Morgagni hernias (MH) have been retrospectively reviewed by the authors. RESULTS: Their ages at presentation ranged from 7 months to 11 years. There were 4 males and 3 females. The majority of patients had repeated chest infections. The diagnosis was made on chest radiograph and barium enema. All patients were operated through the abdomen (5 upper midline, 2 laparoscopic approach). The hernia sacs were excised and the defects repaired in all patients. DISCUSSION: Clinical awareness, early diagnosis and surgical treatment especially with laparoscopic correction, are important factors. CONCLUSION: Surgical correction is needed for asymptomatic MH in children to obviate the risk of complications and because the treatment is easy.

Congenital esophageal stenosis due to tracheobronchial remnants is a rare malformation whose diagnosis may be difficult. It is characterised by the abnormal presence of congenital tissue of tracheal origin in the esophageal wall, which is responsible for the narrowing of the esophagus. We report 2 cases whose treatment was surgical after failure of esophageal dilations. The presence of tracheal-bronchial tissue was confirmed by histological examination of the operative piece. Outcome was favourable and the final result was excellent. Recently, endoscopic ultrasonography has been proved useful in the diagnosis of congenital esophageal stenosis due to tracheobronchial remnants by showing the presence of cartilage, which explains the failure of dilation. The high rate of perforation in these cases is due to brutal fragmentation of the cartilaginous rings. Surgical resection of esophageal stenosis with the tracheobronchial tissue appears the only treatment susceptible to completely suppress the stenosis and its consequences.

Cardiac dysfunction with pulmonary edema following scorpion envenomation (SE) has been documented only in a few isolated case reports. We conducted a systematic hemodynamic study in five consecutive patients (mean age, 21.6 +/- 8 years) presenting with pulmonary edema occurring a few hours (9.6 +/- 5.2 hours) after SE. All patients had increased pulmonary capillary wedge pressure (mean, 25 +/- 1.8 mm Hg) while the systemic vascular resistance was elevated only in one. The stroke volume index was markedly depressed (21.7 +/- 3.6 ml/sq m) whereas cardiac index was normal or slightly decreased (2.5 +/- 0.4 L/min/sq m). Cerebral infarct and sudden cardiac arrest were the cause of death in two patients. In the three survivors, all the hemodynamic disturbances and respiratory abnormalities disappeared within a few days. We conclude that cardiac dysfunction was found in all five patients and this was reversible in the three surviving the acute episode.

Tracheal gas insufflation (TGI) of pure oxygen combined with mechanical ventilation decreases dead space and increases CO2 clearance. In the present study, TGI was used in six patients with ARDS who met extracorporeal membrane oxygenation criteria and who were severely hypoxemic and hypercapnic despite optimal pressure-controlled ventilation. This open clinical study aimed to investigate the effects of 4 L/min continuous flow of oxygen given via an intratracheal catheter. PaCO2 decreased from 108 +/- 32 to 84 +/- 26 mm Hg (p < 0.05), and no significant change in PaO2 (68 +/- 18 vs 96 +/- 43, p = 0.06). There was no change in airway pressures and hemodynamic variables. A slight increase in end-expiratory and end-inspiratory volumes with TGI possibly occurred, as seen on tracings from respiratory inductive plethysmography (Respitrace). We conclude that TGI improves tolerance of limited pressure ventilation by removing CO2, but it may induce changes in lung volumes that are not detected by ventilator measurements.

Mortality of the adult respiratory distress syndrome (ARDS) remains high and could be increased by pulmonary barotrauma induced by positive-pressure mechanical ventilation. Extracorporeal CO2 removal combined with low-frequency positive-pressure ventilation (ECCO2R-LFPPV) has been proposed to reduce lung injury while supporting respiratory failure. Use of this technique in 23 patients resulted in the following: a dramatic and highly significant increase of PaO2 obtained rapidly with ECCO2R-LFPPV, allowing subsequent reduction in inspired oxygen fraction; a reduction of the risk of barotrauma evidenced by a significant decrease in pressures and insufflated volumes; a survival rate of 50 percent. Bleeding was the only complication related to the technique and was the cause of death in four patients. This method allowed improvement in gas exchange along with reduction of the risk of barotrauma caused by the ventilator.

The effects of aprotinin, a broad-based proteinase inhibitor, in the management of hemorrhagic complications during prolonged venovenous extracorporeal CO2 removal in patients with adult respiratory distress syndrome are not evaluated. In two patients, aprotinin infusion was added to heparin to treat bleeding, occurring after few days of bypass and responsible for respiratory and hemodynamic deterioration. After aprotinin infusion (loading dose of 2 x 10(6) kIU followed by a continuous infusion of 5 x 10(5) kIU/h) combined with heparin, bleeding vanished until the end of bypass.

OBJECTIVE: To evaluate the possibility of reducing ventilator settings to "safe" levels by extrapulmonary gas exchange with IVOX in ARDS patients. DESIGN: Uncontrolled open clinical study. SETTING: Medical Intensive Care Unit of a University Hospital. PATIENTS: 6 patients with ARDS who entered into IVOX phase II clinical trials. INTERVENTIONS: The end-point of this study was to reduce ventilator settings from the initial values, recorded on the day of inclusion, to the following: peak inspiratory pressure < 40 cmH2O, mean airway pressure < 25 cmH2O and tidal volume < 10 ml/kg. Trials to achieve this goal were made on volume-controlled ventilation within the 24 h before and after IVOX insertion. Comparison of the results achieved during these trials used Wilcoxon test. RESULTS: Before IVOX implantation reduction of ventilator settings was not possible in the 6 patients, despite a non-significant increase in PaO2/FIO2 was achieved. IVOX permitted significant decrease in PaCO2 (from 60.5 +/- 15 to 52 +/- 11 mmHg; p = 0.02) before any modification of the ventilatory mode. After IVOX insertion, a significant decrease of the ventilator settings was performed: peak and mean airway pressures dropped from 44 +/- 10 to 36.8 +/- 6.7; p = 0.02 and from 26.3 +/- 5.6 to 22.5 +/- 3.9 cmH2O; p = 0.02, respectively. Concommitantly, PaCO2 remained unchanged and PaO2/FIO2 increased significantly from 93 +/- 28 to 117 +/- 52; p = 0.04. The interruption of oxygen flow on IVOX was associated with a slight decrease of the oxygen variables. Tolerance of IVOX was satisfactory. However, a significant decrease both in cardiac index and in pulmonary wedge pressures (from 4.5 +/- 1.2 to 3.4 +/- 9; p = 0.03 and from 16 +/- 5 to 11 +/- 2; p = 0.04, respectively) was observed. CONCLUSION: Gas exchange achieved by IVOX allowed reduction of ventilator settings in 6 ARDS patients in whom previous attempts have failed. CO2 removal by the device, may explain these results. Efficacy of IVOX on arterial oxygenation was uncertain.

Cystic lymphangioma is a rare tumour (6% of benign tumours in children), frequently situated in the cervical or axillary region and exceptionally intraabdominal. It arises due to a congenital defect in the connection of the primary lymphatic channels with the central collecting system. It presents clinically either in the form of a pseudo-appendix or pseudo-ascites syndrome or in the form of an abdominal tumour with or without compression of adjacent structures. It can now be easily diagnosed by ultrasonography. Treatment is well defined and consists of surgical resection of the isolated lymphangioma or associated with the adjacent intestine, depending on the site of the tumour. It has a good prognosis.

The ingestion of caustic substances is a frequent accident in the child. The treatment of caustic strictures of the esophagus, which constitute the most frightening complication, varies from conservative treatment to esophageal replacement. We report the preliminary results of a prospective work established since July 1998 and aimed at evaluating the role of pneumatic dilatation in the treatment of these injuries. STUDIED POPULATION: The series included five boys with an average age of six years. Two children were neurologically handicapped. RESULTS: The caustic product was soda (three cases), a dishwasher solution (one case) and bleach (one case). Dysphagia was constant and concerned the semi-fluids in four cases. The stricture was extended over an average length of 4 cm. The total number of dilatations was 36, with an average of seven sessions/patient. No complication was noted. The result was good in four cases. The only failure was noted in a child who presented a gastroesophageal reflux secondary to the scarring phenomena. CONCLUSION: Pneumatic dilatation constitute a therapeutic mean whose results are attested. The best treatment remains, however, preventive: it is the setting out of reach of the child the dangerous products.

UNLABELLED: Esophageal duplications represent 10 to 20% of esophageal malformations and 15 to 20% of digestive duplications. METHODS: The authors report a series of seven cases observed between 1985 and 1999. RESULTS: The sex ratio was 2.5. The diagnosis was made before the age of six months in five cases. The clinical presentation included respiratory signs in six cases and digestive signs in five cases. The diagnosis was made on the association of a mediastinal mass behind vertebral malformation in five cases. The duplication was cystic in five cases and tubular in two. A perforation in the pleura occurred in one case of tubular duplication. The intervention consisted of total excision of the duplication in four cases and subtotal resection in two cases. For the seventh patient, who presented a perforation of the duplication in the pleura, the operation comprised a thoracic drainage associated to feeding gastrostomy. The histologic examination of the six operative specimens confirmed the diagnosis of esophageal duplication. Six patients survived and have favorable evolution with an average follow-up of four years. DISCUSSION: Esophageal duplications represent 15 to 20% of digestive duplications. Their clinical presentations are variable. Their diagnosis is often made before the age of two years, when a posterior mediastinal mass is associated with vertebral malformations. Apart from the tubular form, which is rare, diagnosis is confirmed by the histologic study of the operative specimen. CONCLUSION: Esophageal duplications are rare and often pose a problem of positive diagnosis. Their treatment is surgical and should be undertaken before the appearance of complications.

PATIENTS AND RESULTS: A series of four cases observed in the department of pediatric surgery in Monastir between 1990 and 1998 are reported. The diagnosis was made in the two first days of life. The clinical features associated paleness, shock and abdominal distension. Ultrasonography revealed that the hemoperitoneum was associated with liver hematoma in three cases and with retroperitoneal hematoma in two cases. Three infants required emergency hemostatic laparotomy. The fourth was stabilized by initial resuscitation. One infant died at the age of six months following subarachnoid hemorrhage and subdural hematoma. No complication occurred in the three remaining patients. CONCLUSION: The pathogeny, clinical features and treatment of the hemoperitoneum in the newborn are discussed. The authors stress preventive measures, the only way to decrease the incidence of this neonatal complaint.

The Arnold-Chiari malformation (MAC), ectopic medulla of the cerebral hemispheres, may be the basis of respiratory problems provoked by compression of the respiratory centre. It is associated with numerous respiratory problems in children; there are however few publications related to the association of MAC and ventilatory problems in adults. It was recently suggested and subsequently shown that the syndrome of sleep apnoea (SAS) could occur in relation to MAC. We report a new observation documenting the association of MAC and SAS. The surgical cure of MAC enabling a remission of SAS suggests the existence in this case of a causal relation between the two pathologies. A search for such a malformation by imagery of the occipito-medullary crest should be a part of the work up in SAS when the cause remains undetermined.

In order to assess the benefits of serial assays of C-reactive protein in the course of bacterial meningitis in adults, daily blood samples were taken for CRP measurement during 10 days in 21 consecutive patients (mean age: 24 +/- 8 years) hospitalized for bacterial meningitis principally due to Neisseria meningitidis (n = 15). The highest CRP level (178 +/- 38 mg/l) was present on admission, followed by a regular decrease occurring in uncomplicated meningitis until normal level was achieved on day 9. The CRP kinetics was not influenced by the type of causative micro-organism. This study shows that CRP kinetics in adults is similar to that reported in children. The benefit of CRP assays in optimizing the duration of antibiotic treatment of meningitis needs to be more carefully assessed.
