Perinatally discovered complete tubular colonic duplication associated with anal atresia

Complete tubular colonic duplication (CTCD) is exceedingly rare. The association of CTCD with an anorectal malformation is unusual. This malformation may be found unexpectedly at laparotomy. We present 3 cases of surgically proven neonate CTCD discovered at laparotomy for anal atresia. We reviewed the mode of clinical presentation, the imaging, and laparotomy findings. Our series illustrates that this rare disease presents perinatally in association with anal atresia, with or without other associated anomalies.

Congenital pancreatic cyst with Ivemark II syndrome: a rare case

An infant with congenital pancreatic cyst with Ivemark II syndrome is reported because it is a rare association. The infant had associated situs inversus, asplenia, and complex congenital heart disease. The pancreatic cyst was successfully managed by cystoduodenostomy because of connection to the biliary tract. The infant succumbed as a result of heart failure at age 2 months. Prognosis depends on the presence of life-threatening malformations.

Titanium nitride oxide coating on rough titanium stimulates the proliferation of human primary osteoblasts

OBJECTIVES

Titanium is widely used in contemporary endosseous implantology and there is considerable thrust to further promote osseointegration by implant surface modifications. The aim of this study was to evaluate the effect of a titanium-nitride-oxide (TiNOx) coating on commercially pure microroughened titanium by assessing the proliferation and differentiation of human primary osteoblasts.

MATERIALS AND METHODS

Cell proliferation, gene expression, alkaline phosphatase activity, osteoprotegerin and osteocalcin secretion were analyzed for a time course of 3 weeks, with or without additional stimulation by 1.25(OH)(2) vitamin D(3) 100 nM.

RESULTS

A 1.5-fold increase in the proliferation rate of cells grown on TiNOx-coated titanium as compared with uncoated surfaces was observed. SEM views indicated that the cells' normal morphology with their numerous extensions was maintained. The differentiation process on the TiNOx surface was only affected to a minor degree and translated into a slight delay in osteoblast maturation when compared to uncoated titanium.

CONCLUSION

Pending confirmation of these results in vivo, TiNOx coatings could potentially accelerate and enhance osseointegration.

Contribution of laparoscopy in the abdominal tuberculosis diagnosis: retrospective study of about 11 cases

OBJECTIVE

Abdominal tuberculosis is one of the most frequent extra-pulmonary localizations. Its diagnosis is difficult and may lead to a delayed prescription of specific treatment. This study is aimed at stressing the role of laparoscopy associated with a biopsy in the diagnostic confirmation of abdominal tuberculosis particularly in doubtful cases.

METHODS

The diagnostic features of 11 cases hospitalized for abdominal tuberculosis in the Paediatric Surgery Department of Fattouma Bourguiba Hospital in Monastir for a 6-year period (2001-2006), were evaluated retrospectively. The diagnosis of abdominal tuberculosis was substantiated histopathologically by laparoscopy in all cases. The epidemiological and clinical characteristics along with the laboratory, radiological and histological data were studied.

RESULTS

Eleven cases of abdominal tuberculosis with a mean age of 5.6 years were diagnosed. It was peritoneal tuberculosis in all cases and associated with intestinal localization in one case. A conversion to laparotomy was practiced in three patients: appendicular plastron in one case, pseudo-tumor aspect of an intestinal loop in another case and because of their pathological aspect appendicectomy and caecum biopsy in the third. The diagnosis was confirmed histologically by biopsies in nine cases and on excision pieces in the other two cases. All patients had an uneventful course with an antituberculosis treatment.

CONCLUSION

Abdominal tuberculosis is still frequent in Tunisia. Because of its non-specific clinical presentation and the limited means of investigation, a laparoscopy with biopsy should be practiced as first line diagnostic tool in case of doubtful abdominal tuberculosis. The earlier the diagnosis is established and an adapted antituberculosis treatment is started, the better the prognosis is.

Management of multiple echinococcosis in childhood with albendazole and surgery

BACKGROUND/PURPOSE

Multiple echinococcosis (ME) is a severe disease in childhood inaccessible to an initial radical surgical treatment. The aim of this study was to evaluate the efficacy of Albendazole in ME and to discuss the role of surgery in this pathology.

METHODS

Eleven patients were included in a prospective study between 1996 and 2004. ME was defined by the presence of 10 or more cysts in the same organ. Albendazole was given as 10 mg/kg daily continuously. Treatment outcome was defined as cure, improvement, stabilization or deterioration. Surgery was discussed after 1 year of treatment.

RESULTS

Our patients totalized 296 cysts located essentially on the liver (178 cysts) and the lungs (78 cysts). With exclusive Albendazole therapy, 57.7% pulmonary cysts and 96% peritoneal cysts were considered as cured. This rate was only 31.5% in hepatic localization. After surgical therapy, 67.4% of hepatic cysts were cured. No productive biliary fistula was observed. Two patients were operated laparoscpically. The total treatment duration ranged between 1 and 5 years. Parasitologic examination of operated cysts showed that 30% of them were viable even after 3 years of treatment.

CONCLUSION

Albendazole has proven a strong efficacy in pulmonary and peritoneal localizations. A complementary surgical treatment is often necessary in hepatic localizations and it is facilitated with previous Albenazole therapy. Combination of ABZ and surgery seems to have encouraging results and must be applied for those patients. The high rate of viable cysts after medical therapy is problematic and must incite to develop new antihelminthic agents.

Congenital bilobar emphysema

Congenital bilobar emphysema is reported to be extremely rare. We describe 3 cases, and we review the diagnosis problems and treatment methods of this childhood respiratory tract pathologic condition.

Transverse testicular ectopia: a three-case report and review of the literature

OBJECTIVES

To describe the embryologic, clinical, and therapeutic features of transverse testicular ectopia (TTE) and to review the literature on similar cases.

METHODS

Three cases of TTE were discovered accidentally during surgery for inguinal hernia and undescended testes; a persistent Müllerian duct syndrome (PMDS) was associated in 1 case. We also performed a literature search for other reports of TTE.

RESULTS

A conservative surgical approach was chosen: transseptal orchiopexy was preferred in 2 cases and the Müllerian remnant was preserved in the first case.

CONCLUSIONS

TTE is a rare anomaly that usually presents as a unilateral cryptorchidism and a contralateral descendent testis with an associated hernia. In suspected cases, laparoscopy and ultrasonographic evaluation may be helpful in diagnosing this condition before surgery. Surgery, transseptal orchiopexy, is highly recommended to manage TTE especially when vasa deferentia are fused. In case of PMDS, the authors preferred preserving Müllerian remnants because of the risk of vas deferens and testicular blood supply damage. Recently, laparoscopy is useful for both diagnosing and management of TTE and associated anomalies.

Ovarian inflammatory myofibroblastic tumor in children

Inflammatory myofibroblastic tumors or inflammatory pseudotumors are uncommon solid tumors that are highly vascularized, have an intermediate prognosis, and are associated with local recurrence, and rare metastasis. Inflammatory myofibroblastic tumors (IMT) most often are seen in the lung of young adults, but there have been reports of these tumors occurring in children, in various sites. The authors report a case of an ovarian IMT arising in a six-year-old girl (third case reported in the literature), treated by a right adnexectomy with uneventful postoperative course, and discuss recent reports.

[Polyorchidism: report of 2 cases and review of the literature]

Polyorchidism is a rare urogenital abnormality. The authors report two cases in children aged 3 years and 5 years with left ectopic testis. Surgical exploration demonstrated two testes on the left side with a third testis on the right. Descent of the two testes into the left hemi-scrotum was performed. The authors review the management of polyorchidism in the light of these two cases.

Laparoscopic treatment of hydatid cyst of the liver in children. A report on 34 cases

PURPOSE

This study evaluated the safety and efficiency of laparoscopically treated liver cysts in children.

METHODS

From September 2001 to July 2004, 34 patients underwent laparoscopic treatment of hydatid cysts of the liver. All patients had chest x-ray, abdominal sonography, and hydatid serology. The different stages of the procedure were the same as in open surgery: puncture, aspiration, injection of scolicidal agent, reaspiration, removal of proligerous membrane, and resection of the dome.

RESULTS

The patients' mean average age was 7 years and 7 months (range, 3-14 years). The number of cysts ranged from 1 to 10 with a diameter of 40 to 150 mm (mean diameter, 65.5 mm). One case had a mesenteric associated hydatid cyst, another splenic hydatid cyst. The average length of hospital stay was 5 days (range, 4-14 days). No per- or postoperative complications were reported. At 12 to 45 months follow-up, no recurrence has been reported.

CONCLUSION

Laparoscopy represents an excellent approach for the treatment of hydatid cyst of the liver in children.

Post-surgical follow-up (by ELISA and immunoblotting) of cured versus non-cured cystic echinococcosis in young patients

The study was designed to determine comparatively the prognostic value of immunoblotting and ELISA in the serological follow-up of young cystic echinococcosis (CE) patients exhibiting either a cured or a progredient (non-cured) course of disease after treatment. A total of 54 patients (mean age 9 years, range from 3 to 15 years) with surgically, radiologically and/or histologically proven CE were studied for a period up to 60 months after surgery. Additionally, some of the patients underwent chemotherapy. Based on the clinical course and outcome, as well as on imaging findings, patients were clustered into 2 groups of either cured (CCE), or non-cured (NCCE) CE patients. ELISA showed a high rate of seropositivity 4 to 5 years post-surgery for both CCE (57.1%) and NCCE (100%) patients, the difference found between the two groups was statistically not significant. Immunoblotting based upon recognition of AgB subcomponents (8 and 16 kDa bands) showed a decrease of respective antibody reactivities after 4 years post-surgery. Only sera from 14.3% of CCE patients recognized the subcomponents of AgB after 4 years, while none (0%) of these sera was still reactive at 5 years post-surgery. At variance, immunoblotting remained positive for AgB subcomponents in 100% of the NCCE cases as tested between 4 and 5 years after surgical treatment. Immunoblotting therefore proved to be a useful approach for monitoring post-surgical follow-ups of human CCE and NCCE in young patients when based upon the recognition of AgB subcomponents.

Spontaneous perforation of the extrahepatic bile duct in infancy: report of two cases and literature review

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.

[Cystic echinococcosis in children in Tunisia: fertility and case distribution of hydatid cysts]

Cystic echinococcosis, which commonly starts during childhood or adolescence, is a serious problem of public health in Tunisia. For 121 children (161 cysts), the localization and fertility of cysts as well as viability of their protoscoleces were determined. Results indicated that the lung was the primary localization of cyst (59%) followed by the liver (35%). Children's infection is more frequent in male than in female (sex ratio 1.96) and the greatest number of cases is observed in the 4-9 year age groups (94 cases). The fertility of the cyst was independent of its site or its size and no incidence of age of children was detected. Nevertheless, the fertility rate is higher in females than in males for the liver localization.

[Intussusception owing to pathologic lead points in children: report of 27 cases]

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.

Sténose congénitale de l'œsophage par hétérotopie trachéobronchique : à propos de 2 cas et revue de littérature

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.

Genetic differences between Tunisian camel and sheep strains of the cestodeEchinococcus granulosusrevealed by SSCP

Ovine and dromedary Echinococcus granulosus isolates from Tunisia were identified as G1 and G6 strains based on polymorphism of the mitochondrial cytochrome C oxydase CO1. Single strand conformation polymorphism (SSCP) was used in order to examine the genetic variation within and between Tunisian G1 and G6 strains and to estimate the extent of selfing. The dromedary isolates are genetically distinct from sheep isolates (high value of genetic variation between populations: Fst= 0.46). No significant deficiency in heterozygotes was found in sheep isolates, whereas heterozygote deficiency (suggesting selfing) was found in a limited number of camel isolates.
