Ultrasonographic screening for cystic echinococcosis in sheep in Tunisia.

Sheep from the areas of Fondouk-Jeddid, Bir Mchergua and El Fahs, located in the Northeast of Tunisia, were examined by ultrasonography between 2001 and 2004 in order to assess their infection with Echinococcus granulosus, the agent of hydatid disease, and to evaluate this method as an efficient aire for hydatid cysts. A total of 1039 sheep, aged between 1 and 14 years was examined. The highest prevalence was found in sheep aged more than 8 years. The least infected animals were aged between 1 and 2 years. All hydatid cysts detected by ultrasound were located in the liver. In all age-groups, the dead cysts were more numerous than viable cysts. Eighteen positive sheep were autopsied and a comparison between ultrasound and autopsy results was performed. The results showed a prevalence of about 40% for the three areas. Ultrasonography allowed the cysts, deep or superficial to localize in the central or left part in relation to the caudal vena cava of the animals. Consequently, all the cysts were not detected with this technique. This work shows that ultrasonography confirms the importance of ovine hydatid cyst in Tunisia and that its use as a mass screening approach for cystic echinococcosis in sheep could be helpful for the monitoring of this disease in a hydatid control program without great stress for the animals.

Cystic hydatic disease in sheep: treatment with percutaneous aspiration and injection with dipeptide methyl ester.

An in vitro and in vivo study was conducted to show the effect of dipeptide methyl ester on the protoscolices of Echinococcus granulosus and in naturally infected sheep. Easily punctured cysts were located by ultrasonography. A PAIR and PAI method were performed by the injection of dipeptide methyl ester into these cysts at a final concentration of 110 mmol/L. Follow-up was conducted monthly by ultrasonography. After injection of the compound, the sheep were sacrificed at different times from 6 to 17 weeks. The size and the morphological aspect of treated cysts were noted. Samples were collected for histology and electron microscopy. In conclusion, these studies revealed significant and rapid detachment of the membrane of the treated cyst and alteration of the inner membrane in less than 5 min after injection of the drug, confirming the effect of the compound on the laminated layer of the parasite.

[An exceptional combined malformation: duplication of the lower urinary tract, the vulva and the posterior intestine].

The authors report the case of a 6 year old girl with bladder duplication, urethral duplication, genital system duplication associated with colonic duplication and low double anorectal anomalies. This patient presented two hemivertebrae at T9 and T11. This girl died a few days after admission from internal obstruction and septicemia. The embryological features especially the possibility of associating two different embryopathogenic mechanisms in the pathogenesis of this combined malformation (Split notochord syndrome and fissure of the urogenital system), and diagnostic and therapeutic aspects are studied in relation to this case and a review of the literature.

[Asphyxiating thoracic dysplasia associated with hepatic ductal hypoplasia, agenesis of the corpus callosum and Dandy-Walker syndrome].

The authors report on a case of a newborn with asphyxiating thoracic dysplasia who died 36 h after birth. This chondrodysplasia was associated with hepatic ductular hypoplasia, agenesis of the corpus callosum and Dandy-Walker malformation. To our knowledge, such an association has not previously been reported in the literature.

[Femoral hypoplasia--unusual facies syndrome].

We report a new case of femoral hypoplasia-unusual facies syndrome (FH-UFS). A review of the literature disclosed fifty-five previously published cases. Both boys and girls can be affected. The syndrome includes bilateral femoral hypoplasia; facial dysmorphism with a cleft palate, micrognathia, a long philtrum, a thin upper lip, and a short broad-tipped nose; dysplasia of the hips; and hypoplasia of the fibulae. Other malformations may be found, including skeletal defects and visceral (especially cardiovascular and genitourinary) abnormalities. Etiopathogenesis of this syndrome remains unknown. Some investigators have suggested a link between the FH-UFS and caudal dysplasia in infants born to diabetic mothers.

[Contribution of echography in the course and treatment of acute osteomyelitis].

In a series of 43 cases of acute hematogenous osteomyelitis, the ultra sound (US) allowed the diagnosis and the accurate localisation of the sub periosteal abscess. The early surgical treatment of the sub periosteal abscess since its nascent or, at least, before its rupture into the soft parts, changes completely the development of the illness and reduces considerably the chronicity forms. This early surgical treatment allows also to isolate rapidly the germ and to test its sensitiveness to antibiotics, which insures a better effectiveness to the medical treatment.

[Post-traumatic dissecting aortic aneurysm in adolescents].

The authors report a case of chronic post-traumatic dissecting aneurysm associated with myocardial contusion in a 13 year old adolescent. They stress the rarity of this condition in children and discuss the diagnostic contribution of various imaging techniques.

[Hydatid cysts in children. Diagnostic and therapeutic aspects. Apropos of 1195 cases].

Hydatid cysts represent a true social problem in Tunisia where 2.1% of rural inhabitants are affected. Hydatid disease is responsible for 10% of the country's surgical activity and costs approximately 800 $ per patient. From April 1967 through January 1987, 1,195 cases of hydatid cyst in children aged 2 to 15 years were treated at the Children's Hospital in Tunis. The involved organ was the lung in 643 cases, the liver in 486 cases, the spleen in 27 cases, and the kidney in 18 cases. With the exception of seven patients with malignant forms, surgery was always performed, with a 1.4% mortality rate and a 2% morbidity rate. We analyze the diagnostic and therapeutic particularities of the various locations of hydatid cyst. Diagnosis rests mainly on ultrasound findings and treatment on conservative procedures as hydatid disease in children carries a good prognosis.

An autosomal recessive disorder with retardation of growth, mental deficiency, ptosis, pectus excavatum and camptodactyly.

Two strikingly similar brothers issued from consanguineous parents in the second degree present the following patterns of anomalies: retardation of growth, mental deficiency, ocular abnormalities, pectus excavatum and camptodactyly. The ocular abnormalities include ptosis, microphthalmia and hypertelorism. No endocrine or metabolic aberrations were found. The authors conclude that the disorder has probably an autosomal recessive mode of transmission.

[Cardiac failure caused by arteriovenous malformation in the area of Galen's vein. Treatment by endovascular embolization].

The authors report a case, in a 7-month-old girl, of cerebral arteriovenous malformation with a vein of Galen ectasia, complicated by a congestive heart failure and hydrocephalus. The clinical diagnosis was carried out by fontanelle auscultation and confirmed by: cerebral echography. Döppler exploration, computerized tomography and cerebral angiography. A cerebral embolization permitted reduction of cardiac insufficiency and stabilisation of the hydrocephalus.
