optimum interval between intracavernosal injection and penile doppler for accurate diagnosis of vasculogenic erectile dysfunction

One hundred and seventeen patients [age range 29-77 years] with erectile dysfunction were evaluated using power Doppler ultrasonography with a linear probe [7 MHz]. Diagnostic tests were undertaken after transducer injection with papaverine in titrated doses. The grade of erection, the peak systolic velocity [PSV], end- diastolic velocity [EDV] and resistive index [RI] were recorded sequentially at 2.5 minutes interval for up to 25 minutes. According to the response to the highest injected dose of papaverine, the patients were classified into two groups. Group A included patients with elongation without rigidity of the penis and group B included patients with normal rigid erection. After injecting papaverine, group A included 63.2% of the patients and group B included 36.8% of the patients. There was a significant difference in the peak systolic velocity [PSV] between the two groups at five minutes after injection, but there was no significant difference after ten minutes. On the other hand, a significant difference between the two groups in EDV and RI was found at five minutes after injection; but a significant difference was found at ten minutes after injection

Bone mineral measurements in the lumbar spine of Egyptian children using quantitative computed tomography

This study was designed to determine age and gender based normative values for spinal bone mineral density [BMD] in Egyptian children. Five hundred and twenty two healthy Egyptian subjects aged 2 months to 12 years [292 males, mean age 5.6 years; 230 females, mean age 6.2 years] were recruited for BMD assessment. BMD was measured by quantitative computed tomography [QCT] using General Electric Scanner Prospeed Plus with 512 x 512 matrix. The study population were grouped according to age into Group-I that included 141 cases [86 boys and 55 girls, aged 2 months to less than 2 years, mean 1.3 years], Group-II included 218 cases [123 boys and 95 girls, aged 2 to less than 6 years, mean 3.6 years] and Group-III that included 163 cases [83 boys and 80 girls, aged 6 -12 years, mean 8.2 years]. Bone mineral density for each group was calculated in addition to the mean and standard deviation. Drawings representing the mean of bone mineral content in different age groups were also made. Finally we compared our data with those in the literature

Sagittal reformatted CT scan in evaluation of the role of the agger nasi cell and nasofrontal bony beak in chronic frontal sinusitis

The present study aimed at investigation of the role of the Agger nasi cell and the nasofrontal bony beak as a cause of compromised or obstructed frontal recess and chronic frontal sinus disease. The relationship of these structures to the frontal recess had been studied with the use of conventional and helical computed tomography [CT] in the coronal and axial planes along with sagittal reformatted images in 30 patients with chronic frontal sinusitis. Data from coronal and sagittal images as well as data from conventional and helical scanning C.T were compared. Endoscopic frontal recess clearance was performed for 25 out of 30 patients with chronic frontal sinusitis. Endoscopic examinations revealed prominent Agger nasi cell in 86.7% and 33.3% septal deviation. Coronal C.T images revealed 63.3% compromised frontal recess by Agger nasi cell, while prominent nasofrontal beak was seen in 13.3% of cases. During the follow-up period, 22 patients had complete resolution of all symptoms, 6 of them had occasional attacks of frontal sinusitis, 3 patients showed no improvement at all and 2 patients required further surgery

Value of both ultrasonography and barium enema in diagnosis and reduction of intussusception in children

The aim of this study was to evaluate the values of both U/S and barium enema in diagnosis and hydrostatic reduction of acute non complicated intussusception in children. All these selected patients had no signs or symptoms of peritonitis with balanced serum electrolytes and the duration of symptoms was less than 48 hrs. Nasogastric tube inserted to decompress the stomach and IV cannula inserted for IV fluid replacement and sedated by diazepam. The diagnostic accuracy and sensitivity by both U/S and barium enema was 100% with positive sonographic target signs of intussusception [dough nut sign in TS and pseudo-kidney sign in LS]. 20 patients with non complicated acute intussusception were subjected to non- surgical reduction. They were divided into two groups for hydrostatic reduction of intussusception: Group A included ten patients subjected for reduction of intussusception by saline enema guided by U/S and Group B included also ten patients subjected for barium enema reduction under fluoroscopic guide. The results have shown that U/S was equal to barium enema in diagnosis of intussusception but U/S considered superior than barium enema in diagnosis and reduction of intussusception as it can detect another abdominal pathology that could not be diagnosed by barium enema as well as it can save the patient from the hazards of irradiation. Also, the results have revealed that hydrostatic reduction must be fulfilled to non complicated intussusception to save the patients from the hazards and cost of surgical treatment that must be done only in cases of failed hydrostatic reduction and in complicated cases
