The patient is a 17-year-old female. She was suffering from dwarfism, irregular menstruation and obesity. Out of the dwarfism, there were no other neurological abnormalities. The serious clinical examinations were performed, and the cerebral angiography and the CT scan demonstrated the findings of the obstructive hydrocephalus. Namely, enlarged IIIrd ventricle and small IVth ventricle were observed with routine CT scan. Because these findings on CT scan, we thought the hydrocephalus was based on the aqueductal stenosis. The vertebral angiography showed stretched posterior medial choroidal arteries and compressed the basilar tip posteriorly and inferiorly. Moreover, the carotid-angiography demonstrated the following findings, unrolling of the anterior cerebral arteries laterally stretched bilateral lenticulostriate arteries laterally shifted sylvian groups of the middle cerebral arteries, and stretched bilateral internal cerebral veins. Judging from that angiographic findings and CT scan, we thought there would be cystic tumor in the IIIrd ventricle. However, we suspected the IIIrd ventricular tumor, we were not able to differentiated it from the enlarged IIIrd ventricle itself exactly. Because, it's density in CT scan was equaled with that the cerebrospinal fluid. According to above facts, we performed "Amipaque CT ventriculography through the ventricular catheter after V-P shunt. By "the Ampiqque CT ventriculography" we found exactly there was large cystic tumor in the IIIrd ventricle. Their manifestation and some differential diagnosis were discused.

The recombinant inbred (RI) set of strains, AXB and BXA, derived from C57BL/6J and A/J, originally constructed and maintained at the University of California/San Diego, have been imported into The Jackson Laboratory and are now in the 29th to 59th generation of brother-sister matings. Genetic quality control testing with 45 proviral and 11 biochemical markers previously typed in this RI set indicated that five strains had been genetically contaminated sometime in the past, so these strains have been discarded. The correct and complete strain distribution patterns for 56 genetic markers are reported for the remaining RI strain set, which consists of 31 living strains and 8 extinct strains for which DNA is available. Two additional strains, AXB 12 and BXA 17, are living and may be added to the set pending further tests of genetic purity. The progenitors of this RI set differ in susceptibility to 27 infectious diseases as well as atherosclerosis, obesity, diabetes, cancer, cleft palate, and hydrocephalus. Thus, the AXB and BXA set of RI strains will be useful in the genetic analysis of several complex diseases.

A case is presented of 14 year old female with hypothalamic obesity due to hydrocephalus caused by aqueductal stenosis. Evidence of hypothalamic obesity included 1) acute hyperphagia and weight gain, 2) neuroradiology showed hydrocephalus with focal enlargement of the third ventricle, 3) endocrinological studies revealed hyperinsulinaemia and impaired growth hormone (GH) response to arginine, but normal GH response to growth hormone-releasing factor (GRF) and 4) Torkildsen's ventriculo-cisternal shunting resulted in improvement in hyperphagia and obesity.

The authors report two cases of pseudotumor cerebri in patients taking lithium for treatment of bipolar disorder. Pseudotumor cerebri is a poorly understood syndrome characterized by chronic headaches, bilateral papilledema, and increased intracranial pressure without localized neurologic signs or symptoms, intracranial mass, or hydrocephalus. Ventriculography, computed tomography, and nuclear magnetic resonance imaging reveal normal or small ventricles. Multiple etiologies may include Vitamin A toxicity, obesity, head trauma, hypothyroidism or hyperthyroidism, prolonged steroid therapy or its withdrawal, Addison's disease, Cushing's disease, pituitary insufficiency, and lithium therapy. Patients treated with lithium whose antidiuretic hormone-cyclic adenosine monophosphate mechanism is disturbed are most likely to develop pseudotumor cerebri via disregulation of sodium balance, thyroid-stimulating hormone production, and glucose metabolism. The authors recommend careful medical monitoring to avoid iatrogenic effects of lithium, including pseudotumor cerebri.

Endocrinological findings were identified in 60% of 90 shunted patients with an isolated hydrocephalus, namely dwarfism in one third and abnormal proportions, obesity, sexual precocity and various combinations in 9-15%. Different causes of these findings were observed. But none of the cases had a malfunction of the shunt at the time of this study.

Two male patients from one family are reported, who are affected with congenital hydrocephalus, mental retardation, short stature, obesity and hypogenitalism. Most probably the mode of inheritance is X-linked recessive.

A Caucasian female, aged 28 years, presenting with obesity and investigated for primary amenorrhoea, was found to have hydrocephalus due to a stenosis of the foramen of Magendie. Endocrine investigations showed an isolated gonadotrophin deficiency. Complete recovery was obtained by a ventricular-cardiac shunt, which led to the return of menses, a normal pregnancy, and then a return to normal weight.

A 55-year-old man had hydrocephalus caused by a third-ventricular tumor. Mentation improved after ventricular shunting and radiation therapy. Progressive hyperphagia, obesity, memory impairment, and hypersomnolence developed 13 months later, and he died 2 years after diagnosis. At necropsy, a gangliocytoma filled the third ventricle, resulting in compression and necrosis of the ventromedial and posterior hypothalamic nuclei. Clinical manifestations were attributed to these lesions.

Percentage body fat of 35 children with spina bifida and 129 age-matched normal children was measured by underwater weighing and skinfold thickness to assess obesity. Percentage body fat of patients below five years was similar to that of controls; however, 58 per cent of patients above six years had an increased percentage of body fat. The neurological level and ambulatory ability were associated with percentage body fat. A significant correlation between percentage body fat and hydrocephalus suggests that the metabolic and nutritional maladaptation is caused not only by these patients' physical inactivity but also by the condition itself. Appropriate nutritional and mobility programmes should be started early to prevent the development of obesity.

The central autonomic network (CAN) is an integral component of an internal regulation system through which the brain controls visceromotor, neuroendocrine, pain, and behavioral responses essential for survival. It includes the insular cortex, amygdala, hypothalamus, periaqueductal gray matter, parabrachial complex, nucleus of the tractus solitarius, and ventrolateral medulla. Inputs to the CAN are multiple, including viscerosensory inputs relayed on the nucleus of the tractus solitarius and humoral inputs relayed through the circumventricular organs. The CAN controls preganglionic sympathetic and parasympathetic, neuroendocrine, respiratory, and sphincter motoneurons. The CAN is characterized by reciprocal interconnections, parallel organization, state-dependent activity, and neurochemical complexity. The insular cortex and amygdala mediate high-order autonomic control, and their involvement in seizures or stroke may produce severe cardiac arrhythmias and other autonomic manifestations. The paraventricular and other hypothalamic nuclei contain mixed neuronal populations that control specific subsets of preganglionic sympathetic and parasympathetic neurons. Hypothalamic autonomic disorders commonly produce hypothermia or hyperthermia. Hyperthermia and autonomic hyperactivity occur in patients with head trauma, hydrocephalus, neuroleptic malignant syndrome, and fatal familial insomnia. In the medulla, the nucleus of the tractus solitarius and ventrolateral medulla contain a network of respiratory, cardiovagal, and vasomotor neurons. Medullary autonomic disorders may cause orthostatic hypotension, paroxysmal hypertension, and sleep apnea. Neurologic catastrophes, such as subarachnoid hemorrhage, may produce cardiac arrhythmias, myocardial injury, hypertension, and pulmonary edema. Multiple system atrophy affects preganglionic autonomic, respiratory, and neuroendocrine outputs. The CAN may be critically involved in panic disorders, essential hypertension, obesity, and other medical conditions.
