Computed tomography in agenesis of the right lobe of the liver.

Congenital agenesis of the right lobe of the liver is a rare anomaly. In a case report the diagnosis was made by computed tomography. A retro- or suprahepatic location of the gallbladder and compensatory hypertrophy of the left liver lobe and/or caudate lobe may give support to the diagnosis. Before diagnosing congenital agenesis of the lobe, lobar atrophy due to cirrhosis, cholangiocarcinoma or any other predisposing conditions should be eliminated.

Comparison of blood flow velocities of the extraocular vessels in patients with pseudoexfoliation or primary open-angle glaucoma.

PURPOSE: To evaluate orbital blood flow velocities in patients with pseudoexfoliation glaucoma (PXG) or primary open-angle glaucoma (POAG). METHODS: Blood flow velocities in the ophthalmic, central retinal, and posterior ciliary arteries were evaluated by color Doppler imaging in 26 patients with PXG, 28 patients with POAG and 30 age-matched normal control subjects. The results were compared. RESULTS: Compared to the control subjects, patients with PXG showed statistically significant decreases in the mean peak systolic and end-diastolic velocities and increased mean resistive indices in all vessels except for the ophthalmic artery mean peak systolic velocity (p < 0.05). Patients with POAG, when compared to the control subjects, showed statistically significant decreases in the mean end-diastolic velocities and increased mean resistive indices in all vessels measured (p < 0.05). No statistically significant differences were found in the mean blood flow parameters between POAG and PXG. CONCLUSION: Blood flow velocities of the retrobulbar vessels are decreased in patients with PXG. Reduced blood flow velocities may be secondary as well as contributory to exfoliative glaucomatous damage. Although there was no significant difference in the mean blood flow parameters between POAG and PXG, alterations of retrobulbar vessels might be associated with different pathogenic mechanisms of PXG.

Various clinical aspects of DIDMOAD (Wolfram) syndrome.

The association of juvenile diabetes mellitus (DM), diabetes insipidus (DI), optic atrophy (OA) and sensorineural deafness (D) is known as DIDMOAD or Wolfram syndrome. Aside from these four cardinal features, a wide variety of abnormalities of the nervous system, urinary tract and endocrine glands have been described in this syndrome. In this report, the clinical features of six patients with DIDMOAD syndrome are presented. All six patients had DM. Five of the six patients had DI, five OA and five displayed abnormal audiogram findings. In addition, two had goiter, two delayed puberty, one seizure and one mental retardation with depression attacks. Urinary tract dilatation was recorded in five patients. Four patients developed typical complications of DM. One of them had overt nephropathy and arthropathy despite the short duration of DM. In addition, this patient had diabetic retinopathy, which is considered to be rare in this syndrome.
