[Diagnosis and treatment of adult polycystic kidney disease].

A review of 20 polycystic kidney disease patients in admitted to Kaohsiung Medical College Hospital is herein reported. In this series 60% of the patients were in the fourth to sixth decades of life at the time of diagnosis. The average age was 50 years. The disease was generally more commonly found in the females than in male subjects. Flank pain and gross hematuria was the most common presenting symptom in these cases. In 70% of the patients hypertension were noted, besides 55% of patients have associated liver cysts and 9% of the patients have associated pancreatic cystic diseases. In a comparison of ultrasonography, CT scans, renal angiography, intravenous pyelography and retrograde pyelography in the evaluation of polycystic kidney disease, it was found that CT scans and ultrasonography had more than a 90 per cent diagnostic accuracy rate, while intravenous pyelography had only a 30 percent accuracy rate. Because of improved treatments such as antibiotic and hemodialysis techniques the five-year survival rate of patients, with polycystic kidney diseases, may be increased.

Treatment of recurrent thyroid cysts by injection of tetracycline or minocycline.

We analyzed the effects of tetracycline hydrochloride or minocycline hydrochloride sclerotherapy on 66 recurrent thyroid cysts. All were hemorrhagic lesions except one serous cyst; cytologic study showed all were benign. On average, three treatments were given until resolution or the patient became unavailable for follow-up. The cumulative frequency of cyst disappearance was 33%, 45%, 52%, and 59% after 1, 2, 3, and 4 treatments. Five additional patients had cyst resolution after six to 19 treatments, and the serous lesion did not resolve. Cysts requiring more than two treatments were larger at presentation than those resolving after one or two treatments. Side effects in 179 treatments were local pain lasting ten to 20 minutes in 4.5%, radiated pain lasting one to two hours in 4.5%, fatigue lasting one to two days in 3.9%, and a febrile sensation lasting one to two days in 2.8%. Hemorrhagic thyroid cysts can usually be cured by repeated tetracycline or minocycline sclerotherapy with tolerable side effects.

Clinical significance of ultrasonography, computed tomography, and biochemical tests in the rapid diagnosis of gallstone-related pancreatitis: a prospective study.

Real-time ultrasonography (US), computed tomography (CT), and biochemical tests were prospectively performed to detect gallstones in 88 consecutive patients immediately after the onset of an attack of acute pancreatitis. The sensitivity of biochemical tests was 84.6% when the patients had three or more positives of five parameters [including serum bilirubin, alkaline phosphatase (AP), gamma-glutamyl transpeptidase (GGT), alanine transaminase (ALT), and alanine transaminase-aspartate transaminase (ALT-AST) ratio]. The sensitivity, specificity, and accuracy were 71.8, 98.0, and 86.4% for US, and 52.9%, 100%, and 79.5% for CT. The sensitivity, specificity, and accuracy were improved to 82.1, 100, and 93.2% by the combination of US and CT, and 94.9, 100, and 97.7% by the combination of US and biochemical tests. Adding CT to the combination of US and biochemical tests resulted in only a slight improvement in sensitivity and accuracy. In conclusion, a combination of US and biochemical tests can provide the best noninvasive method in rapidly detecting gallstones as an etiological factor in acute pancreatitis. Computed tomography is not cost-effective. A positive result of biochemical tests despite a negative finding in US calls for an intensive search for gallstones by further investigation with endoscopic retrograde cholangiography or repeated US examinations.

High-resolution real-time ultrasound in Peyronie's disease.

Sonography is not considered to be a radiation hazard; it is noninvasive and can be widely used for examining external genitalia. We examined six cases of Peyronie's disease of the penis by high-resolution real-time ultrasound. The sonographic findings include a thick echogenic plaque with echogenicity similar to or higher than the tunica albuginea; a calcified plaque in thickened tunica albuginea; and are occasionally associated with calcification in the corpora cavernosa. Sonography may clearly localize the abnormal thickened area of collagen deposition and calcification. Repeated sonography after intracavernosal papaverine injection may further confirm the correlation of the plaque and the abnormally curved erectile penis. Doppler ultrasound may be used for further evaluation of the vascular condition if impotence coexists.
