Multiple cardiac lipomas and pericardial lipomatosis: multidedector-row computer tomography findings.

Being rare tumors of the heart, cardiac lipomas are usually discovered incidentally during non-cardiac-related examinations of the chest. Although they are reported to be typically solitary, multiplicity has been described in tuberosclerosis patients. Here we reported the multidedector-row computer tomography (MDCT) findings of a nontuberosclerosis case with multiple cardiac lipomas along with pericardial lipomatosis, who presented with symptoms of left heart failure after a hysterectomy surgery but otherwise healthy before that operation.

Lower extremity venous changes in pneumoperitoneum during laparoscopic surgery.

BACKGROUND: The effect of pneumoperitoneum on veins of the lower limbs related to the intra-abdominal working pressures during laparoscopic cholecystectomy has not been thoroughly investigated. We tested the hypothesis that working pressures do not affect the venous haemodynamics in the lower limbs. METHODS: The cross-sectional area and peak flow rates of femoral and saphenous veins in the right groin were measured in 60 patients divided into two groups according to the intra-abdominal working pressures (11 vs 14 mmHg). All measurements were carried out preoperatively and at predetermined periods during and after laparoscopic cholecystectomy by colour Doppler ultrasonography. One-way anova and chi(2) test were used for the analysis of demographic data. For the repeated measures, anova and Student's t-test were used for statistical analysis. The probabilities less than 0.05 were accepted as statistically significant. RESULTS: The cross-sectional area of the veins increased, whereas the peak flow rate in veins decreased during pneumoperitoneum. Comparing the peak flow rate in the saphenous vein at the third intraoperative measurement, there is statistically significant difference between the two groups (P < 0.05). CONCLUSION: The degree of intra-abdominal pressure affects the haemodynamics of the peripheral veins. Pneumoperitoneum during laparoscopy causes stasis in the peripheral veins. It is reasonable to use routine prophylaxis for deep vein thrombosis, in the light of these findings.

Mechanical coil embolization of pulmonary arteriovenous malformations.

PURPOSE: To report our experience with mechanical coil embolization of pulmonary arteriovenous malformations. MATERIAL AND METHODS: Coil embolization was performed in 6 men (mean age, 21.1 years; age range, 20-23 years) with pulmonary arteriovenous malformations between 1999 and 2004. Five F Cobra catheters and various sized coils were used for embolization. Clinically, cases were followed-up every 3 months for one year and every 6 months thereafter, with a mean total follow-up period of 2.3 years. RESULTS: Complete primary occlusion was achieved in all patients. There were no complications related to the procedure and no problems were reported during follow-up period. CONCLUSION: Treatment of pulmonary arteriovenous malformation cases with coil embolization is an effective option.

Testicular microlithiasis in pediatric age group: ultrasonography findings and literature review.

PURPOSE: To evaluate the occurrence of testicular microlithiasis in pediatric age group by means of ultrasonography (US) examinations and to review the literature for pediatric testicular microlithiasis cases accompanied by testicular and extratesticular tumors. MATERIALS AND METHODS: Nine children aged 3-16 years (mean age, 9.2 years) with testicular microlithiasis had been evaluated with US in a period ranging from 6 months to 6 years. In addition to the testicular ultrasonographic evaluation, liver US and abdominopelvic US were performed in all patients. RESULTS: Typical testicular microlithiasis findings were seen in a total of 17 testicles. In one patient, testis did not exist in either the scrotum or the inguinal canal or the abdomen unilaterally. None of the patients displayed a focal lesion during the evaluation. The abdominal ultrasonographic findings were normal in all patients. CONCLUSION: Although no tumoral lesion accompanying testicular microlithiasis or occurring in the course of evaluation was detected in this study, larger population and longer control periods are required, considering the co-existence of benign and malign lesions with testicular microlithiasis in the literature.

Duodenal intramural hematoma due to blunt abdominal trauma.

A 14-year-old boy was admitted to the hospital with the complaints of epigastric pain and vomiting for three days following epigastric trauma. Physical examination revealed a palpable mass in the epigastrium without any signs of peritoneal irritation. Vital signs, biochemical analysis, chest and abdominal x-rays were normal. Abdominal US, CT and upper gastrointestinal endoscopy showed that there was a well-defined duodenal intramural mass suggesting hematoma. Intraabdominal solid organs were normal and we did not observe free air or extravasation of contrast media. Therefore, we followed up the patient by US. The hematoma completely resolved 48 days after the trauma.

MR urography in pediatric uropathies with dilated urinary tracts.

PURPOSE: To determine the diagnostic value of magnetic resonance (MR) urography in children with urinary tract dilatation. MATERIALS AND METHODS: Twenty-five children between the ages of 4 months and 13 years (19 males and 6 females, mean age 6.5 years) were evaluated with T2 weighted and contrast-enhanced T1 weighted MR sequences. Results were compared with findings obtained with ultrasonography (n=25), intravenous urography (n=18), Tc99m- DTPA scintigraphy (n=16), and/or micturating cystouretrography (n=13). RESULTS: MR urography provided a superior imaging of urinary system dilatation, the site and the etiology of obstruction, and both regular and complicated kidney duplication than did conventional imaging methods. MR urography that used T2 weighted sequences was able to demonstrate 29 of 32 (90.6%) abnormal renal collecting systems. Fourteen of 21 (66.7%) normal systems were revealed by heavily T2 weighted images. Forty-six of 51 (90.2%) renal collecting systems could be shown by T1 weighted sequences. With this sequence, however, five collecting systems (9.8%) could not be shown secondary to poor renal function and/or dilution of contrast agent within the dilated urinary tract. CONCLUSION: In children, MR urography may replace conventional uroradiological methods.

[Mechanical coil embolization of pulmonary arteriovenous malformations].

PURPOSE: To report our experience with mechanical coil embolization of pulmonary arteriovenous malformations (PAVM) MATERIAL AND METHODS: Coil embolizations were performed in 6 men (mean age 21.1, age range 20-23 years) with PAVM between 1999 and 2004. Five F Cobra catheters and various size coils were used for embolization. Clinically, cases were followed in every 3 months of their first year and 6 months in the following years with a mean time of 2.3 years. RESULTS: Complete primary occlusion was achieved in all patients. There were no complications related to the procedure. No problem was reported in the follow-up period. CONCLUSION: Treatment of PAVM cases with coil embolization is a good option.

Bone mineral density in children with nocturnal enuresis.

In enuretic children there is a significantly higher incidence of fine and gross motor clumsiness, delayed developmental milestones, slower and poor linear growth, and these patients are shorter than normal children. Skeletal maturation of enuretic children has been determined with bone age in only two studies before, but to our knowledge bone mineral content of enuretic children has not previously been determined by bone mineral density measurement. Bone mineral density was measured by the dual-energy x-ray absorptiometry method in children with nocturnal enuresis and compared with that of a control group to detect whether there were any delay in bone development and any decrease in bone mass. Thirty enuretic children were compared with a control group of 40 healthy children with respect to body height and weight measurements, daily calcium intake, serum calcium, phosphorus and ALP levels, chronological and bone ages, and bone mineral density measurements. Of the parameters compared, bone age was significantly retarded, and bone mineral density was significantly reduced in children with enuresis (8.3 +/- 1.9 vs 9.7 +/- 2.3 years; p = 0.01, and 0.5476 +/- 0.07 vs 0.6077 +/- 0.05 g/cm2; p = 0.001, respectively). Chronological ages demonstrated a significant correlation with the bone ages in both the study and control groups (r = 0.852, p < 0.001, and r = 0.844, p < 0.001, respectively). However, the mean chronological age was significantly greater than the mean bone age in the study group (p < 0.001), whereas the mean chronological age was not significantly different from the mean bone age in the control group (p = 0.514). To clarify the exact mechanism responsible for these manifestations of skeletal maturation retardation, the relationship between the maturational delay of the central nervous system connections or the effect of any perinatal insult and the retardation in skeletal maturation remains to be determined.

Walker-Warburg syndrome variant.

A Turkish patient with cobblestone lissencephaly and eye involvement without characteristic muscular changes for congenital muscular dystrophy died at the age of 3 months presented with neonatal apneic periods and generalized seizures. Serum creatine kinase level, electromyography, chromosome analysis and blood biochemistry were normal. Unilateral microphthalmia, retinal dysplasia and internal strabismus were the ocular findings. Magnetic resonance imaging clearly demonstrated the thickened, irregular, nearly agyric cobblestone cerebral cortex with underlying unmyelinated white matter, hydrocephalus, hypoplastic corpus callosum, brain stem and cerebellum with retrocerebellar cyst and posterior cephalocele.

Computed tomography-guided percutaneous drainage of splenic abscesses.

OBJECTIVE: The aim of the study is to evaluate the role of computed tomography (CT)-guided percutaneous drainage in the management of solitary splenic abscesses. MATERIALS AND METHODS: Sonography and CT were used in the initial diagnosis of splenic abscess in patients with vague left upper quadrant pain and/or fever. Solitary splenic abscesses of nine male patients whose ages varied between 21 and 27 years (mean age: 24.7 years) were percutaneously drained under CT guidance. Puncture with 18-gauge Chiba needles and coaxial guidewire technique was used for insertion of six or eight French pigtail catheters. Antibiotics in accordance with the microbiological results were also given adjuvant to drainage. Follow-up examinations were performed by sonography, daily for the first week and weekly for the next 7 weeks, and by CT at the end of first, fourth and eighth weeks. RESULTS: All patients tolerated the intervention well, except for one complicating with splenic rupture and hemorrhage, who underwent emergency splenectomy. The remaining eight patients recovered within 4 weeks without any splenic sequela. A mean of 3.9 days was needed before removing the drainage catheter based on regression criteria. DISCUSSION AND CONCLUSION: CT-guided percutaneous drainage of splenic abscesses may be proven effective and is superior to splenectomy in selected cases, as it preserves host immunity.

Evaluation of bone mineral density in chronic glue sniffers.

Although acute and chronic toxic effects of inhalant (glue) abuse have been well demonstrated on many organ systems, the effects on the skeletal system and bone mineral content of young people with this addiction have, to our knowledge, not yet been investigated by bone mineral density measurement. In the present study bone mineral density was measured by the dual-energy X-ray absorptiometry method in 25 children and adolescents with inhalant abuse and compared with that of a control group (n=30) to detect whether there was any delay in bone development or any decrease in bone mass. Chronological age, height and weight, serum calcium, phosphorus and alkaline phosphatase levels of the study group were not significantly different from those of the control group (p>0.05), whereas bone mineral density was significantly reduced in the study group (p=0.001). Teenagers with glue vapor abuse may carry an increased risk of future fracture even though the exact mechanism(s) responsible for the toxicitiy of glue vapor on bone metabolism remains to be determined. To ascertain the exact component of glue responsible for bone demineralisation may be of value in proposing a change in the composition of the glue. Education and/or rehabilitation programs currently have the greatest importance in preventing and overcoming the harmful effects of this public health problem which is so common in young children and adolescents.
