Staphylococcus aureus costal osteomyelitis with complicated by pleural effusion in a 7-month-old infant: A misleading clinical presentation.

Osteomyelitis is a rare infectious disease in children, predominantly affecting long bones; however, its clinical presentation can be ambiguous if the location is atypical. Costal osteomyelitis is very rare in children and can mimic other pathologies. We present a case of a seven-month-old infant diagnosed with costal osteomyelitis complicated by rupture of a subperiosteal abscess into the pleura. His clinical condition improved with conservative treatment, which included chest drain insertion and intravenous antibiotic therapy without the need for surgical debridement. Rib osteomyelitis represents a potentially severe condition. Early detection is imperative to prevent the necessity for invasive therapies and mitigate long-term complications.

Laparoscopic assisted dismembered pyeloplasty versus open pyeloplasty in UPJO with poorly function kidney in pediatrics.

BACKGROUND: The management of UPJO with poor function kidney, less than 10%, has been the subject of debate for more than a decade. Some authors have recommended nephrectomy, while others favor renal salvage (pyeloplasty). We report our experience with laparoscopic assisted pyeloplasty in pediatric patients with poorly functioning kidneys in comparison with an open approach. MATERIALS AND METHODS: A retrospective study was conducted to review 65 patients who were diagnosed with hydronephrosis and had impaired renal function due to UPJO. The study was conducted in the pediatric surgery departments of Al-Azhar University Hospital and Fattouma Bourguiba University Hospital of Monastir over a period of 20 years. Limited to pediatric patients with UPJO with ≥ Grade III hydronephrosis, antero-posterior pelvic diameter ≥ 20 mm, as well as a renal function equal to or less than 10%, was corrected by laparoscopic assisted or open pyeloplasty. RESULTS: There were 40 cases in group A who underwent laparoscopic assisted pyeloplasty, and 25 cases in group B who underwent open pyeloplasty. There were no complications or difficulties during the operation. The mean operative time in group A was 90 ± 12 min, while in group B, it was 120 ± 11 min. The renal assessment parameters significantly improved in both groups. In group A, the mean split renal function was 7.9 ± 1.3% and increased to 22.2 ± 6.3%. In group B, the mean split renal function was 8.1 ± 1.1% and increased to 24.2 ± 5.1%. However, the differences between both groups in terms of pre-operative and post-operative renal functions were statistically insignificant. CONCLUSION: Laparoscopic assisted pyeloplasty is an effective treatment for patients with poorly functioning kidneys, especially those with less than 10% function. While this surgical procedure requires shorter operative times, it yields functional outcomes that are comparable to open approach.

Peritoneal Hydatid Cysts in Children: A Case Series of Rare Echinococcosis Localization.

Peritoneal hydatid cysts are rare in children even in endemic areas. The primary or secondary origin of this site remains controversial, especially in children. Secondary peritoneal hydatid cysts are mainly the result of spontaneous or traumatic rupture of concomitant liver cysts or the leakage of cystic content during surgery. The purpose of our study is to present the largest case series of peritoneal hydatidosis in children. In addition, we aimed to assess the clinical and paraclinical findings as well as the management of echinococcosis at this location in children. The present case series is a study of ten children with peritoneal hydatid cysts, who underwent surgical intervention between 2013 and 2018 in the Pediatric Surgery Department, University of Monastir (Monastir, Tunisia). The mean age of the children was six years. All children presented abdominal pain, and underwent ultrasonography and contrast-enhanced computed tomography of the abdomen. Two patients had been operated on for lung hydatid cysts six months prior to the study. In two cases, radiologic investigations revealed the presence of an uncomplicated hepatic hydatid cyst located in segments II and IV. All patients underwent surgery, of which four underwent laparoscopy. Post-surgery, all patients received albendazole for three months, and the follow-up period was uneventful. Currently, all patients are in good health. Peritoneal hydatid disease is frequently secondary to the rupture of a primary hepatic cyst. Diagnosis is performed by abdominal ultrasound, computed tomography, and a positive serology result. Open or laparoscopic excision can be combined with medical treatment.

Capitonnage seems better in childhood pulmonary hydatid cyst surgery.

BACKGROUND: Pulmonary hydatid disease remains an important healthcare problem. Conservative operative interventions including cystotomy or cystotomy with capitonnage are the two commonly used techniques. However, there is no scientific consensus over selection of these operative interventions. AIM: The aim of this study is to compare these two methods: capitonnage and uncapitonnage in the surgery of childhood pulmonary hydatid cyst in regard to the postoperative period. METHODS: This is a retrospective analysis of 136 patients operated for pulmonary hydatid disease between January 2010 and July 2017 according to two techniques. Group A was cystotomy with capitonnage (n = 76), and group B was cystotomy alone (n = 60). We compared the postoperative outcomes. RESULTS: Our data showed pneumothorax(PNO) and emphysema were seen in 30% of Group B and only in 13.2% in Group A, and the persistence of residual cavity in 23.3% in Group B and 7.9% in Group A (p = 0.014). We have not seen any case of recurrence with capitonnage. CONCLUSION: We conclude that capitonnage appears to prevent PNO and emphysema formation and a remaining residual cavity in the long term with a significant difference. And it prevents prolonged postoperative air leak and hospitalization with a slightly nonsignificant difference. It is difficult to say with absolute certainty that the noncapitonnage group is inferior to the capitonnage group, since several factors can influence the evolution.

First molecular evidence of the simultaneous human infection with two species of Echinococcus granulosus sensu lato: Echinococcus granulosus sensu stricto and Echinococcus canadensis.

Cystic echinococcosis is a widespread zoonotic parasitic disease especially in Tunisia which is one of the most endemic countries in the Mediterranean area. The etiological agent, Echinococcus granulosus sensu lato, implies dogs and other canids as definitive hosts and different herbivore species as intermediate hosts. Human contamination occurs during the consumption of parasite eggs passed in the environment through canid feces. Hydatid cysts coming from a child operated for multiple echinococcosis were collected and analyzed in order to genotype and to obtain some epidemiological molecular information. Three targets, ribosomal DNA ITS1 fragment, NADH dehydrogenase subunit 1 (nad1), and mitochondrial cytochrome c oxydase subunit 1 (CO1) genes, were amplified and analyzed by RFLP and sequencing approach. This study presents the first worldwide report in human of a simultaneous infection with Echinococcus granulosus sensu stricto (genotype G1) and Echinococcus canadensis (genotype G6) species. This is also the first report of the presence of E. canadensis in the Tunisian population which argues in favor of a greater importance of this species in human infestation in Tunisia than previously believed.
