Gadolinium-enhanced MRI in central nervous system Behçet's disease

Two cases of central nervous system Behçet's disease, studied by gadolinium-enhanced MRI, are presented. In one patient, whose clinical picture was dominated by a brain syndrome, the gadolinium enhancement resolved with clinical improvement, although the hyperintense areas in the mesencephalon on T2-weighted images persisted. In the second, who had a pseudobulbar palsy and a mild right hemiparesis, there were many abnormal areas, but an enhancing focus in the posterior limb of the left internal capsule was probably the lesion responsible for the hemiparesis.

Post-thyroidectomy hypocalcemia: does arterial ligation play a significant role?

To assess the possible role of truncal ligation of inferior thyroid arteries on post-thyroidectomy hypocalcemia, a prospective study was carried out on 80 patients. Bilateral subtotal thyroidectomy was performed for non-toxic nodular goiter in two groups. Inferior thyroid arteries were ligated bilaterally in 50 patients but not ligated in 30 patients. In both groups mean serum calcium levels on the first and second postoperative days were found to be significantly lower than preoperative levels. However these falls were similar in both groups. We conclude that bilateral truncal ligation of inferior thyroid arteries is not a factor that may cause hypocalcemia due to vascular insufficiency of parathyroid glands.

Eales disease with internuclear ophthalmoplegia

Eales disease is an idiopathic type of retinal perivasculitis characterized by recurrent retinal and vitreous hemorrhages. Neurologic involvement is rare. We report the case of a patient with Eales disease who had internuclear ophthalmoplegia thought to be a neurologic manifestation of this disease.

Hot water epilepsy

The clinical and EEG features of 10 patients with hot water epilepsy were presented. Eight of the 10 cases were male. The mean age of onset was 4.7 years. In four patients partial and in six cases generalized seizures were seen. Three patients also had non-hot water precipitated seizures. Interictal EEGs showed generalized abnormalities in eight and focal abnormalities in two cases. CT was performed and found normal in two patients. Anticonvulsant therapy was instituted for all patients. In six cases with adequate follow-up, complete remission was obtained in four and the frequency of the seizures was decreased in two, with anticonvulsant therapy.

Fascicular oculomotor nerve palsy in neuro-Behçet's disease

A 43-year-old man with Behçet's disease developed a left oculomotor palsy and a right elevation paresis. His clinical picture was consistent with an isolated fascicular third cranial nerve palsy, considering the mass effect of a large left capsulothalamic lesion extending down into the mesencephalon, which was visualized by CT and (more precisely) by MRI. The patient's clinical status was improved with steroid and immunosuppressive therapy, and radiologic abnormalities resolved markedly in a month.

Left occipital hypoperfusion in a case with the Asperger syndrome

The Asperger syndrome, a less severe variant of autism, has drawn increasing interest among child psychiatrists. Cerebral blood flow studies with autistic subjects have failed to reveal consistent findings. We are reporting a case with the Asperger syndrome, whose single photon emission computed tomography showed left occipital hypoperfusion.

[Parallax technics]

Regarding radiologic interpretation, parallax determines the different x-ray appearance of the same objects from various exposuring directions. In the present study the horizontal and vertical shift sketch method is used. This study is carried out on 31 patients admitted to Oral Diagnosis and Radiology Department. After recording the location of impacted teeth to the special forms, surgical intervention is performed. The susceptibility of this study is found 100 per. cent. Only in one mesio-dens case we had an conflict. This finding is also being discussed. The sophisticated details of the method is being described.
