An 8-year-old boy presented with an ocular torticollis that had appeared many months after a ptosis repair. The three-step test was positive for a superior oblique palsy. However, at the time of surgery the forced duction test showed a marked restriction in depression of the eye. These findings were duplicated before the second procedure normalized the ocular movements. The surgical microscope was of great help for the extensive dissection necessary to correct the condition. The fourth step, the forced duction test, was essential for accurate differential diagnosis between true superior oblique palsy and a mechanical hypertropia.

Central blindness in a 3.5-year-old crossbred steer was evaluated by electrodiagnostic techniques. When admitted the steer was depressed, head pressed, and circled to the left. Ptosis and absence of menace response were seen with the right eye, while the left eye was normal; direct and consensual pupillary light responses were normal in both eyes. Brainstem auditory evoked potentials and electroretinograms were essentially normal. The flash visual evoked potential (VEP) was greatly reduced upon stimulation of the right eye, while no VEP peaks could be recognized after flash stimuli were presented to the left eye. The amplitude of the electroencephalogram was depressed over right occipital cortex. Multiple brain abscesses were detected on postmortem examination adjacent to the left thalamus, in the left caudal cerebrum, and right frontal cerebrum. Corynebacterium pyogenes was cultured from abscess exudate; however, no origin for the infection could be determined. Both eyes were microscopically normal. The thalamic abscesses were postulated to have produced the EEG depression. Correlations between the VEP abnormalities and the abscess locations are discussed, based on proposed central nervous system generators of the VEP.

Autonomic dysfunction was diagnosed in a 2.5-year-old spayed domestic shorthair cat. The cat had an 8-day history of progressive anorexia, signs of depression, constipation, weight loss, and intermittent regurgitation. Physical examination findings were signs of depression, dehydration, cachexia, bradycardia, bilateral nonresponsive mydriasis, prolapse of both nictitating membranes, dry oral and nasal mucous membranes, and urinary bladder atony. Thoracic radiography revealed megaesophagus. The cat lacked esophageal motility and had a decreased gastric emptying rate. Providing adequate fluid intake, electrolyte balance, and nutrition is a major problem in the management of dysautonomic cats. We were able to provide adequate nutritional support for this patient, using total parenteral feeding and, later, enteral nutrition using a nasogastric tube. Results of an ocular pharmacologic study indicated that the mydriasis and prolapse of the nictitating membrane were attributable to complete autonomic denervation of the eye. Using the method described, topical, autonomic-stimulating agents may assist the clinician in diagnosing dysautonomia in the feline. This report describes a syndrome that is well recognized in the United Kingdom and has the potential to develop in the United States.

14 children with anorectal prolapse have been treated by injection therapy with 25% saline solution. Experimental studies have shown no noticeable reactions between rectum and surrounding area, as far as adhesion and thus rectal fixation are concerned. Manometric examinations show an increased contraction tendency of the Musculus puborectalis after injection, which should lead to a depression of the kink at the rectosigmoidal junction and to a healing of the prolapse. The associated stool-regulating measures contribute a lot to remedy the prolapsed rectum.

An acute administration of MCI-2016 at the doses of 30, 100 and 300 mg/kg (p.o.), and 10, 20 and 30 mg/kg (i.p.) produced a slight CNS depression in rats, such as, sedation, ptosis, decrease in motor activity and systemic muscle relaxation. In a direct physical dependence test, rats were fed the MCI-2016-admixed food together with drinking water ad libitum for 24 hours daily for 51-71 days (mean MCI-2016 intake 29.9-210.7 mg/kg/day), on the gradedly increased dosage schedule with a dosage level of 0.25 and 0.5 mg/g food to 4 mg/g food. In a natural withdrawal following administration of MCI-2016, no significant withdrawal signs were observed in any group. In a naloxone-precipitation test the rats that were treated with MCI-2016-admixed food did not show any withdrawal signs. In a substitution test in either morphine or barbital dependent rats, no suppression of withdrawal signs or maintenance of dependence were observed by cross-administration of MCI-2016. In conclusion, MCI-2016 was considered to have no physical dependence potential.

Microinjections of kainic acid and ferrous sulfate into basomedial nuclei of both amygdalae resulted in the formation of the generator of pathologically enhanced excitation (GPEE), as evidenced by the epileptical activity (EpA) registered in both nuclei. EpA of different intensity and pattern could be retained for more than three weeks. Hyperactive basomedial nuclei played the role of a primary pathological determinant which caused the complex of emotional and behavioural disorders. Continuous motor depression at the early stages alternated pathologically enhanced activity at the later stages. A number of signs could be considered as the evidence of the affective disorders (motivation suppression, enhanced irritation, anxious excitation). Stereotype behaviour, immobility, rigidity, different types of vegetative disorders (ptosis, constipation, piloerection, loss of weight, respiratory arrhythmia, dystrophic symptoms) were observed in most animals. The emotional, behavioural and vegetative disorders described are compared to the manifestations of the depressive syndrome.

We examined two sisters with lid retraction on adduction, the classic sign of levator-oculomotor synkinesis. In both women, the left eye was involved. No history of trauma or ocular surgery or complaints of diplopia were elicited, and both had good visual acuity and full ocular motility. Each exhibited 2 mm of left upper lid elevation on adduction and 4 to 6 mm of lid elevation on adduction with depression. In one of the sisters, 1 mm of ptosis was present in straight ahead gaze in the involved eye, which increased to almost 2 mm on abduction, but full levator function was observed. Four other family members in three consecutive generations were similarly affected, suggesting an autosomal-dominant mode of inheritance. To our knowledge, this type of isolated levator-oculomotor synkinesis has not been reported previously on a congenital and inherited basis.

Episodic mitral regurgitation due to ischaemia of one or both papillary muscles was studied in a review of 39 cases with complementary investigations and compared with previously reported data. The condition occurred after myocardial infarction in 69 p. 100 of cases (usually after inferior infarction: 54 p. 100) associated with ischaemia of the controlateral territory; there was no history of myocardial infarction in 31 p. 100 of cases. The patients were usually elderly (73 years), often hypertensive (77 p. 100) and diabetic (62 p. 100). The clinical syndrome was that of severe anginal pain, mitral regurgitation and left ventricular failure which was critical in some cases. The ECG showed typical ST depression (4.1 +/- 1.6 mm) especially in the antero-lateral leads; left bundle branch block (28 p. 100) with left axis deviation (18 p. 100), sometimes associated with changes of chronic infarction (64 p. 100) was also recorded. Mitral regurgitation and left ventricular failure regressed almost completely in typical cases between attacks, whilst the ECG showed slight residual sub-endocardial ischaemia (ST depression of 1.5 +/- 0.4 mm) in 30 cases and/or subepicardial ischaemia observed in the anterolateral leads in 13 cases. Phonomechanographic recordings (n = 32) showed moderate mitral regurgitation (1-2/6), usually parasystolic (47 p. 100) or early and mid systolic (36 p. 100) in 87.5 p. 100 of cases between attacks, aggravated by handgrip exercise and improved by trinitrin administration. Echocardiography (n = 27) only showed mitral valve changes in 2 patients (increased density of the papillary muscle in 1 case and prolapse of the anterior leaflet in 1 case); however, segmental wall hypokinetic (51 p. 100) or dyskinetic (15 p. 100) motion, was common with increased left ventricular end diastolic dimensions (mean 56.3 +/- 8.0 mm) and decreased fractional shortening (mean 0.30 +/- 0.07) (67 p. 100). Left atrial dimensions were increased (mean 39.7 +/- 6.4 mm) in 52 p. 100 of patients. Thallium 201 myocardial scintigraphy (n = 32) showed hypofixation in 57 (36 p. 100) and a lacuna in 23 (14 p. 100) of the 160 segments analysed. Left ventricular angioscintigraphy (n = 27; 135 segments) showed hypokinesia in 72 segments (53 p. 100); 2.7 segments per patient), akinesia in 19 segments (15 p. 100; 0.7 segment per patient) and dyskinesia in 2 segments (1.5 p. 100); 0.1 segment per patient). The global ejection fraction was 46 +/- 13 p. 100. Coronary angiography (n = 8) showed significant diffuse atherosclerosis.(ABSTRACT TRUNCATED AT 400 WORDS)

Brain-tissue shifts associated with drowsiness, stupor, and coma were studied by clinical examination and CT scanning in 24 patients with acute unilateral cerebral masses. Studies were performed soon after the appearance of the mass to detect the earliest CT changes associated with depression of consciousness. Contrary to traditional concepts, early depression of the level of alertness corresponded to distortion of the brain by horizontal displacement rather than transtentorial herniation with brain-stem compression. Horizontal displacement of the pineal body of 0 to 3 mm from the midline was associated with alertness, 3 to 4 mm with drowsiness, 6 to 8.5 mm with stupor, and 8 to 13 mm with coma. Moreover, drowsy or stuporous patients and some comatose patients had widened cisterns between the tentorial edge and the midbrain on the side of the mass, suggesting that the space was not filled by herniated medial temporal lobe. Downward displacement of the pineal body, indicating central transtentorial herniation, did not occur. Compression of one hemisphere by the other anteriorly (transfalcial herniation) was inconsistently related to alertness, though very large anterior displacements may have caused stupor in some patients. Current concepts of the pathoanatomical nature of depressed consciousness, based on pathological material obtained well after clinical examinations, may require revision, because they do not reflect early brain-tissue distortions.

A 64-year-old female visited Kawatetsu Chiba Hospital complaining of left retro-orbital pain. A month before, she had experienced ptosis and diplopia, that had been releaved two days later by corticosteroid. On admission, she had no neurological deficits except for minimal anisocoria, with the left pupil larger than the right. There was no cutaneous manifestation of von Recklinghausen's disease. Skull X-ray films showed depression of the floor of the sella turcica on the left side. CT scans demonstrated a parasellar enhancing mass with intrasellar extension. Left carotid angiogram showed intracavernous portion of the internal carotid artery displaced laterally, inferiorly, and anteriorly. With a tentative diagnosis of laterally extending pituitary adenoma, a transsphenoidal operation was carried out, which disclosed a solid tumor locating beside the medially-displaced pituitary gland. The histological diagnosis was typical neurinoma. Parasellar neurinoma is not so common. It is usually difficult to determine the origin of the parasellar neurinoma. Trigeminal neurinoma arising from the Gasserian ganglion is generally recognized to be the most frequent. However, the absence of the trigeminal nerve involvement, unusual CT findings, and angiographical changes in the present case were all different from those of the typical trigeminal neurinoma. We believe that the tumor of this case originated from the oculomotor nerve. Fifteen cases of neurinoma of the oculomotor, trochlear, and abducens nerve have been reported to date. Their clinical features were reviewed.
