Post-operative pain in tonsillectomy: bipolar electrodissection technique vs dissection ligation technique. A double-blind randomized prospective trial.

The two commonly employed methods for tonsillectomy at present are electrodissection and ligature dissection. This study was carried out on 70 patients as a randomized prospective double blind trial to compare the post-operative morbidity of these methods with special reference to pain. The post-operative pain appears to be much less for the ligation dissection technique compared to the electrodissection method except during the first post-operative day. Irrespective of the technique employed for tonsillectomy, the worst pain was experienced on the fifth and sixth post-operative day by almost all of the patients.

[Ultrasonographic evaluation of the kidney, liver and spleen size in children].

BACKGROUND: The aim of our study was to establish a standard growth curve of renal, hepatic and splenic dimensions with respect to age, and to find if any relationship existed between these different curves. PATIENTS AND METHODS: One hundred and fifty abdominal ultrasound studies were obtained on 62 male and 88 female normal children free of any chronic disease, whose ages ranged from 0 to 15 years. Hepatic, splenic and renal dimensions were obtained in a similar and reproducible fashion for all patients. A statistical study of the measurements obtained compared to the age was performed by dividing the subjects into five groups according to age, and after calculating the mean size and variance. RESULTS: Standard growth curves for the liver, kidney and spleen were constructed. Compared to age, splenic size follows the same growth as that of the kidneys, with a constant ratio. The growth pattern of the liver parallel the renal curve with a mean difference of 2.72 cm. CONCLUSION: A moderate enlargement of spleen and liver is difficult to evaluate only by clinical examination. Ultrasound may detect it by using the kidney size as a reference.

[Double hemorrhagic complication of endo-urologic drainage in single kidney].

Hemorrhage is the most worrisome complication of percutaneous renal procedures, and usually occurs early in the postoperative period. The incidence of severe arterial injury is 1 to 2%. We report a patient who had 2 bleeding episodes on a solitary kidney. The first, which occurred early after the procedure, was due to an arteriocaliceal fistula treated by coil embolization. The second bleeding episode occurred two weeks later, and was caused by erosion of a lumbar artery; it was embolized by microparticles. To our knowledge, this is the first report of the imaging findings. In summary, when bleeding occurs after endourologic procedures, renal as well as extrarenal parietal causes should be investigated.

[Acute cholecystitis using computed tomography: usefulness of the trabeculation of the peri-cholecystic adipose tissue].

PURPOSE: To evaluate the significance of pericholecystic fat stranding on CT, and to compare it to other CT findings in patients with acute cholecystitis. MATERIALS AND METHODS: The CT examinations of 14 patients with proven acute cholecystitis were retrospectively reviewed and evaluated for the presence of findings consistent with this diagnosis. RESULTS: The most common CT finding was stranding of the pericholecystic fat (13 patients), followed by gallbladder distension (11 patients). Pericholecystic or perihepatic fluid was present in 6 patients in association with severe acute cholecystitis (6 patients) and biliary peritonitis (2 patients). CONCLUSION: Stranding of the pericholecystic fat was the most common CT findings in patients with acute cholecystitis, followed by gallbladder distension.

[Arteriovenous fistula following femoral angioplasty].

We describe a case of arteriovenous fistula developing at the site of balloon dilatation immediately after percutaneous transluminal angioplasty of the superficial femoral artery. This occurred during an otherwise uncomplicated angioplasty. The fistula was treated by inflating a slightly larger balloon with a good clinical result as confirmed by color Doppler ultrasound. This uncommon complication of angioplasty is not widely recognized.

[Value of sonography in prolonged neonatal jaundice. Findings in 13 cases].

BACKGROUND: Different conditions are associated with a prolonged cholestatic jaundice in the neonatal period: viral hepatitis, biliary atresia and choledocal cyst are the most frequent causes. Laboratory findings are necessary, although they do not permit an etiologic diagnosis in all cases. Serial ultrasonographic study could be proposed for the evaluation of biliary excretion before and after feeding, in order to differentiate between these three conditions. PATIENTS AND METHODS: Between February 1993 and January 1997, 13 newborns (seven girls and six boys) aged from 30 to 186 days, presented with jaundice and conjugated hyperbilirubinemia. They were evaluated by laboratory tests; serial ultrasonographic examinations were performed after 4 hours fasting then 1 and 2 hours after meal. RESULTS: The gallbladder (GB) was visualized in nine patients. In five of these patients, it contracted after feeding suggesting the diagnosis of neonatal hepatitis, that was confirmed by the clinical evolution. In three patients, the GB did not change in size and the diagnosis of biliary atresia was surgically proven. In one patient, a choledocal cyst was visualized and confirmed by surgery. The GB was not identified after 4 hours of fasting in four patients; biliary atresia was suspected and confirmed by surgery. CONCLUSION: Serial ultrasound of the GB is an easy and non-invasive method. It was useful in identifying those conditions requiring surgery in eight patients. We recommend its use as the initial method in the evaluation of neonatal jaundice before the other invasive methods.

[Cavernous dural fistulas: Importance of trans-ocular Doppler ultrasound in evaluating venous patency and therapeutic choices].

Transcranial Duplex scan is a relatively recent diagnostic tool with many unexplored clinical potentials. The authors insist on the role of transocular exploration, as a non-invasive substitute to angiography and discuss two patients with cavernous meningeal arteriovenous fistula, a benign but relatively uncommon disease. In the first patient, in whom symptoms recurred, Duplex scan was able to rule out thrombophlebitis and to show increased flow in the fistula, thus leading to proper treatment. In the second patient, the identification of a periorbital thrombophlebitis innocented the fistula and prompted anti-coagulation. We conclude that besides its diagnostic capabilities, Duplex scan may be helpful in selecting proper treatment and follow-up in specific neurovascular conditions.

Isolated brain metastases of osteosarcoma in a patient presenting with a patent foramen ovale.

We report the case of a patient in whom brain MR imaging was requested for initial symptoms of intracranial hypertension. The presence of multiple intracranial hemorrhagic lesions suggested brain metastases. Body screening showed periosteal osteosarcoma of the left fibula with no lung metastases, but with a patent foramen ovale which probably allowed neoplastic cells to reach the brain without being filtered through the lungs. The conclusion of this study was that a left-right cardiac communication is to be considered in cases of isolated brain metastases from osteosarcoma.

[Imaging aspect of a case of fibrodysplasia ossificans progressiva].

Fibrodysplasia ossificans progressiva is a rare congenital disease that affects children under the age of five years. Soft tissue swelling of the cervical and dorsal regions with local pain, warmth and low grade fever are the early clinical manifestations, usually associated with hallux valgus and microdactily of the fingers and toes. Calcifications of the fascias and muscles cause muscular contractures leading to progressive disability and restrictive lung disease. In the early stage, CT shows edema of the soft tissues and later on, calcifications of muscular fascia. The association of these radiographic and CT findings is specific and should avoid muscular biopsies which are known to be an aggravating factor in this disease.

[A rare cause of diplopia: a sinus cavernous dural fistula. A case report].

Dural fistulas of the cavernous sinus represent a relatively unknown etiology for diplopia. The authors report on a case where combination of MR and transcranial Doppler (especially transocular) helped in diagnostic and therapeutic approach. They propose a new algorithm for the management of diplopia.

["Mirror" intracavernous aneurysms. Therapeutic dilemma apropos of a case with review of the literature].

"Mirror" cavernous aneurysms are exceptional; only 66 such cases having been published until mid-1996. We report on a 68-year-old woman who presented for left exophthalmos, diplopia and neuralgia. MR and angiography demonstrated a giant symptomatic aneurysm on the left side and an incidental small one on the right side. The patient was treated in two sessions: first, she had selective embolization of her right aneurysm; two weeks later, her left carotid artery was sacrificed with detachable balloons, after a well-tolerated occlusion test. This original and successful approach permitted to achieve a reasonable goal when considering the patient's age, operative morbidity, risk of future complications and final result. A review of the pathophysiology, clinical manifestations and therapeutic indications is presented and discussed.

Spontaneous resolution of cholelithiasis in an infant.

Cholelithiasis is an extremely unusual finding in infancy. Hemolytic disease, bile duct abnormalities, intestinal malabsorption have been implicated. Recently, an association of prematurity, bronchopulmonary dysplasia, total parenteral nutrition and furosemide has been reported. Rarely, sonographic discovery of idiopathic gallstones and their subsequent spontaneous disappearance has been reported. We report a case of an 11-week-old infant whose initial sonogram displayed evidence of true gallstone, that later showed resolution on follow-up examinations. In the absence of clinical or imaging evidence of biliary tract disease, we suggest an initial conservative management and follow-up sonograms.
