Primary hydatid disease of the thigh. A rare location.

Primary muscle hydatidosis is very rare, accounting for less than 1% of hydatid cyst locations. Clinical symptoms are insidious and non-specific causing a frequent delay in diagnosis. Intramuscular hydatid disease can cause a variety of diagnostic problems, especially in the absence of typical radiologic findings. We report the observation of an 82-year-old man consulting for inguinal tumefaction with radiological exploration suggestive of hydatid cyst of the adductors muscles. Magnetic resonance imaging (MRI) is helpful in diagnosis, since it reveals a very suggestive aspect and demonstrates the relationship between cysts and adjacent structures. Treatment of muscle echinococcosis is based on surgery, which is curative and incurs a low risk of local relapse.

Pectin extraction from lemon by-product with acidified date juice: rheological properties and microstructure of pure and mixed pectin gels.

The microstructure and the rheological properties of lemon-pectin mixtures were studied and compared to those of pure lemon (high methoxyl: HM) and date (low methoxyl: LM) pectins. Rheological properties were carried out in the presence of 30%, 45% and 60% sucrose, and increasing calcium concentrations (0-0.1%). The presence of date with lemon pectin led to a gel formation at 45% sucrose and in the presence of calcium, which was not the case for lemon pectin alone under the same conditions. It is suggested that lemon and date pectins interacted, leading to gel formations at different gelling temperatures, which were strongly dependent on degree of methylation. These results were confirmed by scanning electron microscopy, which revealed inhomogeneous gels where dense aggregated network and loose, open network areas were present. Addition of calcium to pectin mixture gels led to stronger and faster gel formation.

[Intravesical migration of intrauterine device resulting in stone formation]. / Migration intra-vésicale de dispositif intra-utérin compliquée de lithiase.

The migration into the bladder of an intrauterine contraceptive device (IUCD) by uterine perforation is a rare complication. We report two cases of IUCD which migrated into the bladder and subsequently became calcified. The two patients having had their IUCD respectively for 3 and 13 years. Revealing signs were related to bladder irritation for the first patient and hematuria for the second. The diagnosis was suggested on the plain abdominal X-ray and on ultrasound and was confirmed by cystoscopy. Ballistic lithotripsy of the bladder stone with endoscopic extraction of the IUCD was then performed. Performing a transvaginal sonographic examination of the pelvic organs, especially of the uterine anatomy is interesting before insertion of an intrauterine contraceptive device (IUCD), and repeat transvaginal sonographic examinations immediately after the insertion and 4-12 weeks later are advisable. This approach would permit early detection of any complications related to insertion of the IUCD.

[Percutaneous drainage of splenic fluid accumulations. Apropos of 4 cases]. / Drainage percutané des collections spléniques. A propos de quatre observations.

Four patients with solitary or multiple splenic fluid collections were treated by ultrasound guided percutaneous needle aspiration and drainage. There was one unilocular abscess, three infected hematomas, one large hematoma and a complex lesion with locular and perisplenic involvement. Percutaneous drainage and antibiotics were curative in one patient. Splenectomy was performed because of persistent fever and drainage of pus after 15 days in one case and recurrence of hematoma in an other case. Solitary fluid collection can be effectively treated by ultrasound or computed tomography guided percutaneous drainage. Hematoma represents a cause of failure of percutaneous drainage.
