A case of subacute idiopathic pure pan-dysautonomia--recovery with prednisolone therapy

A 52-year-old man had, after an episode of fever in June 1989, developed orthostatic dizziness followed by sexual impotence, dysuria, decreased sweating and weight-loss, which progressed gradually and reached their maximum seven months after the onset. He was given 400 mg of droxydopa and 8 mg of midodrine HCL per day without apparent benefits, and was admitted to our hospital. His blood pressure (mmHg) and heart rate were 167/102 and 68 in supine position, and 74/41 and 62 in sitting position. Skin was dry. Pupillary reactions were sluggish. Left pupil was slightly irregular. Other cranial nerves, sensory and somatic motor functions were normal. Laboratory tests revealed as follows: slight anemia, ESR 42 mm/hour, serum IgG 2236 mg/dl, CSF protein 64 mg/dl and positive tests for non-specific autoantibodies. Nerve conduction studies and electromyogram were normal. Autonomic function tests showed postganglionic impairments of sympathetic and parasympathetic systems. The sural nerve biopsy disclosed normal myelinated fibers, but decreased unmyelinated fiber density to 60% of the control value. No demyelinating lesions, cell infiltration or amyloid deposits were seen. Under the diagnosis of idiopathic pure pan-dysautonomia, prednisolone, initially 60 mg daily, was added. Within 10 days, he showed marked improvement of general conditions. No exacerbation was seen during reduction or after withdrawal of prednisolone. Repeated tests showed normalizing laboratory data and regression of autonomic deficits. A year after onset he regained normal social life.(ABSTRACT TRUNCATED AT 250 WORDS)     

Statistical analysis of the prostatic cancer patients detected from 1985 to 1989 in and around Gunma prefecture]

Prostatic cancer is one of the most common malignant tumors in the field of urology. The number of patients is increasing rapidly and its importance as a mortal disease is gathering attention. In 1985, we organized a registration system for prostatic cancer patients found in and around Gunma prefecture. In this study, we analyzed the clinical characteristics of the 730 patients registered from 1985 to 1989. The results were as follows. Mean age was 74.0 years old and the number of the patients was the greatest in the eighth decade. Voiding disturbance was the most common chief complaint, followed by pollakisuria, gross hematuria and miction pain. Stage and grade distribution were as follows. Stage A 16.2%, B 21.1%, C 17.0%, D 45.7%, well differentiated 27.4%, moderately differentiated 48.2% and poorly differentiated 24.5%, respectively. A statistically significant relationship between stage and grade was observed. Bone was the most common metastatic site. The highest incidence of bone metastasis was in lumbar vertebra, followed by ribs, ilium, thoracic vertebra and ischium. The value of PAP, ALP and ESR tended to be higher in high stage patients, and that of Hb was lower. Fifty two patients were detected by mass screening. Most of these patients were in an early stage. Most of the patients were treated by hormonal therapy. LH-RH agonists constituted 39.2% of the cases given hormonal therapy.     

Assessment of coronary hemodynamics and myocardial perfusion in patients with syndrome X by digital subtraction angiography and 201Tl-myocardial scintigraphy]

To evaluate coronary hemodynamics and myocardial perfusion, left coronary digital subtraction angiography (DSA) and Tl-201 myocardial scintigraphy were performed in patients with syndrome X. The coronary circulation time (CCT) was significantly prolonged after the injection of isosorbide dinitrate and contrast medium i.c. Apical T1/2 was also prolonged on ergonovine malate provocation test. We suspected that the vascular response of the coronary peripheral artery was impaired, and microvascular spasm probably existed in patients with syndrome X. The prevalence of abnormal myocardial perfusion defect on exercise Tl-201 SPECT in syndrome X was very high, and coronary hemodynamics was significantly disturbed in the group of syndrome X with abnormal Tl-201 SPECT. Tl-201 lung/heart count ratio significantly increased in syndrome X on treadmill test. Because of this, exercise induced left ventricular dysfunction was suspected. We concluded that the main pathophysiological finding of impaired coronary circulation in syndrome X was microvascular spasm.     

Ultrasound study in the diagnosis of primary Budd-Chiari syndrome (obstruction of the inferior vena cava).

Primary Budd-Chiari syndrome, obstruction of the hepatic portion of the inferior vena cava (IVC), is a rare disorder, but relatively prevalent in the Far East, northern India and Africa. Ultrasound examination was carried out on 9 patients with primary Budd-Chiari syndrome. There were 5 men and 4 women aged 27-60 years. In all the 9 cases, the diagnosis was confirmed by cavography and liver histology. Moreover, 7 of the 9 subsequently underwent radical operation using a patch graft. Ultrasonic study showed several characteristic findings suggestive of the syndrome, and frequencies of the main findings were as follows: 1) an echogenic obstructing membrane; 22.2%, 2) segmental obstruction of the IVC; 77.8%, 3) occlusion of the major hepatic veins at the juxtacaval portion; 100%, 4) enlarged inferior right hepatic veins; 55.6%, 5) abnormal intrahepatic venous structures and collaterals; 88.9%. Of these findings, 5) was the most prominent and most characteristic in the diagnosis of the syndrome. It is necessary for early detection of this entity to evaluate carefully intrahepatic venous abnormalities and patency of either the IVC or major hepatic veins on ultrasonic examination. The careful examination for Budd-Chiari syndrome should be done in cases with cryptogenic liver cirrhosis, particularly in countries where the prevalence of the syndrome is high.     

The trajectory of the sympathetic nerve fibers to the rat cochlea as revealed by anterograde and retrograde WGA-HRP tracing

Wheat germ agglutinin-horseradish peroxidase conjugate was injected in the unilateral superior cervical ganglion (SCG), and the projection pathways of postganglionic sympathetic nerve fibers innervating the cochlea were traced in the rat. The labeled axons advanced along the internal carotid artery (ICA), and a few advanced caudally in the major petrosal nerve (MPN) and entered the facial nerve, while the majority ran rostral to the pterygopalatine ganglion at the point where they crossed the MPN in the carotid canal. The rest of the labeled fibers remained on the surface of the ICA and advanced to the cranial cavity. Most of the labeled fibers along the facial nerve joined the cochlear nerve and finally reached the osseous spiral lamina through the spiral ganglion. Some of the labeled fibers ran along the anterior inferior cerebellar artery from the basilar artery which was previously thought to have been the only pathway. We could not find any labeled fiber on the modiolar artery from anterior inferior cerebellar artery in the cochlea. These observations are consistent with our hypothesis that the sympathetic fibers innervating the neural tissues or related structures follow nerve fibers and meninges as matrices of projection pathways rather than arteries.     

Sex cord-stromal tumors of the ovary

The developmental relationship between granulosa and stromal cells in the fetal ovary was reviewed. The proliferation and expression of basic fibroblast growth factor (bFGF) and luteinizing hormone receptor (LHR) of both the granulosa and theca cells was examined in the adult ovary. Ovarian granulosa cell tumors were then studied under light and electron microscopy and for immunohistochemical expression of bFGF and LHR. In the follicular development of the adult ovary, bFGF expression in the granulosa cells was correlated with theca cell proliferation. In ovarian granulosa cell tumors, estrogen-producing tumors showed a stratified or microfollicular pattern being accompanied by theca cells which had ultrastructural features of steroid-production, and these tumor cells exhibited immunoreactivity for bFGF. In contrast, tumors with no apparent hormone-production showed a solid or gyriform pattern without admixture of theca cells, and were negative for bFGF. LHR was expressed in both types of tumor. Accordingly, bFGF may play an important role in association with the theca cell component in granulosa cell tumors.     

Ultracytochemistry of glucose-6-phosphate dehydrogenase in adrenal gland.

The distribution of glucose-6-phosphate dehydrogenase (G6PD) activity has been studied by a copper ferrocyanide method in the adrenal cortex cells of a rat. The site of the G6PDH activity was close to the ribosome between the round mitochondria of zonas fasciculata and reticularis.
