A fifteen yrs old boy developed divergence paralysis following meningitic attack. The ocular examination revealed homonymous diplopia in all gazes when he fixed at further than 13 cm. He had 18 delta esotropia at distance and 7 delta esophoria at near in prism cover test. His stereopsis was excellent at near in House Fly Stereopsis Test. There wasn't much change in ocular examination in 90 days after initial examination.

OBJECTIVES: To develop reliable tools for measuring communication skills in schizophrenia, the present study proposed the concept of communication intelligence, consisting of conversational competence, emotional competence, and empathic competence, and explored its neurobiological underpinnings using regional gray matter volume with healthy people. METHODS: Communicative intelligence scores were obtained from 126 healthy young participants. Correlation analyses between regional volume distributions and communication intelligence subcomponents were conducted using voxel-based morphometry of structural MRI. RESULTS: The significant positive correlations between the regional gray matter volumes with conversational competence were found mainly at the ventromedial frontal gyrus while the negative correlations between the bilateral middle frontal gyrus. With emotional competence, the volume of right superior temporal gyrus was positively and that of bilateral insula was negatively correlated. With empathic competence, the volume of the left middle frontal gyrus was positively and that of the insula was negatively correlated. CONCLUSION: Each of the subcomponents of communicative intelligence scores showed distinctive neurobiological underpinnings. The regions for the subcomponents, which constitute a common network for social cognition and emotion, are highly associated with the regions of the schizophrenia pathology. In conclusion, communicative intelligence scales have neurobiological basis to evaluate social skills of patients with schizophrenia.

PURPOSE: This study was conducted to determine whether low intensity regular exercise following dexamethasone treatment could attenuate steroid-induced muscle atrophy. METHOD: 36 Wistar-rats(90-110g) were divided into six groups: control group(C), dexamethasone treatment group(D), sedentary group after normal sedentary period(C+S), sedentary group after dexamethasone treatment period(D+S), exercise group after normal sedentary period(C+E), and excercise group after dexamethasone treatment period(D+E). D, D+S, and D+E groups received dexamethasone injection(5mg/Kg) for seven days whereas C, C+S, and C+E groups received normal saline injection. Both C+E and D+E groups ran on a treadmill for 60 minutes/day(20minutes/4hours) at 15m/min and a 10degreegrade for seven recovery days. RESULT: Post-weight(body weight before muscle dissection) of D group significantly decreased by 16.03%, and that of D+E group significantly increased by 15.51% compared with pre-weight(body weight before steroid treatment). Type II muscle(plantaris and gastrocnemius) weights of D group were significantly lower than those of C group. Myofibrillar protein contents of type II muscles of D group tended to decrease comparing with C group. In D+E groups, body weights and relative weights of typeII muscles(muscle weight(mg)/post-weight(g)) tended to increase comparing with D+S group. CONCLUSION: It is suggested that steroid- induced muscle atrophy can be ameliorated through low intensity regular exercise after dexamethasone treatment.

In the present study, patients were traumatized with muscle-crushing injuries, or they were non-traumstized. The plasma concentration of potassium and sodium were measured before the induction of anesthesia and at selected intervals after the administration of succinylcholine(SCC) in some patients were inhaled the beta2-agonist, salbutamol (about 800 ug) via an endotracheal tube and in the others were not given it. There was no significant difference in the base lines of potassium and sodium between the traumatized and nontraumatized patients. Salbutamol diminished the rise of potassium(-0.30 to 0.09 mEq/L) but did not affect the plasma sodium level. There was no significant side-effect of this agent, but sinus tachycardia was the only thing noted. These results are consistent with the proposed mechanism that the decrease in serum potassium due to salbutamol is most likely a shift of potassium ions from the extracellular space to the intracellular space. Inhalation of salbutamol may be a useful method for the prevention of SCC induced hyperkalemia without any serious side-effect in patients with preexisting hyperkalemia properties who have gone through traums.

The recent prevalence of syphilis has known to be increased progressively throughout the world, since middle of 1950. In Korea, current trend of increased syphilic infection has became a major public health problem. The authors selected sero-positive patients, among the outpaients of department of dermatology, urology, OB & GY, and physical examination, and performed statistical analysis of this sero-positive patients. Results are as following; 1) Of the 2,007 patients taken physical examination, 30 patient(1.49%) were reactive to VDRL. 2) 0.71% of the total out patients of the dermatologic dcpartment were sero-positive. Annual ratio of the syphilitic patient were increased progressively. 3) Ratio of the syphilitic patients to the total outpatients of OB & GY department was 0.55% and somewhat increased since 1976. 4) In the age distribution, the third decade shared 51.8% of the total sero-positive patients 5) In the sexual ratio. male:female=l: l. 62 in the total sero-positive patients. (male:female=l: 1.06 in the dermatologic department.) 6) In the stage distribution, latent syphilis patients were 59.14% of the total syphilitic patients.

Intermittent exotropia at times is completely controlled by the convergence mechanisms and at other times escapes this control and becomes a manifest exotropia. The treatment of choice is surgical and the treatment is directed at normalization of binocular functions, and recurrence and overcorrection are frequently seen after surgery. Therefore it is important to decide the time and the type of surgery. The author experienced 66 cases of intermittent exotropia in which surgery was done. Surgery was indicated in the cases with deviation of 20 PD or more, deviation of less than 20 PD with asthenopia, exotropia occurred during more than 40% of waking hours, and deterioration of stereoacuity even at early age. Bilateral recession was initial procedure regardless type of intermittent exotropia. In the case with amblyopia, however, R and R was done on the amblyopic eye and in convergence insufficiency type bimedial resection. Lateral Incomitancy was present in 37.9%. The basic type which was shown in 68.2% was the most frequent one. The amount of esodeviation was 15 to 10 PD in 43.9% and 11 to 15 PD in 21.2% on the first postoperative day. The phoria within 10 PD was shown in 95.4% 6 weeks after surgery, in 98.5% 3 months after surgery, and in 93.9% 6 months after surgery. Six months after surgery, 4 cases revealed exodeviation above 16 PD and no case esodeviation. Stereopsis was tested in 54 cases who understood the test before operation and 43 cases(79.6%) showed stereopsis. Nine out of 11 cases who had no stereopsis showed stereopsis after operation. In this study, success rate of first surgery was as high as 93.9% in 6 months follow-up and stereopsis was restored in considerable number of cases in intermittent exotropia compared to other types of strabismus and binocular function could also be restored and improved after surgery.

Anisometropia is caused by axial ametropia and refractive ametropia. Almost all anisometropia in children are known to be caused by axial ametropia. Axial ametropic anisometropia is corrected by the spectacles by Knapp's rule. We experienced 41 patients with anisometropia, in whom the relationship between the difference in axial length in each eye(x) and the difference in refractive error in each eye(y) was linear, y = -0.00758+2.18554x. According to this approximate regression formula, 27 patients(66%) showed axial ametropic anisometropia and 14 patients(34%) showed refractive ametropic anisometropia. Twenty three(85%) out of 27 patients had had amalyopia. Ten patients(83%) at the age of 9 or less improved their visual acuity after amblyopia treatment, but only 4 patients(36%) older than 9 showed mild improvement. In authors' experience, axial ametropic anisometropia can be corrected by spectacles with full amount of refractive error and by proper amblyopia treatment. It is important to diagnose and treat the axial ametropic anisometropia in early childhood, however even in the patients older than 9 years old the visual prognosis is not so hopeless if treated with fully corrected spectacles and proper amblyopia treatment.
