Intracranial Aneurysm*

A case of progressive hypertrophic interstitial neuropathy developed in the median nerve of the right hand is reported. The patient was a 27-year old housewife who had complained of numbness and shooting pain on the median nerve distribution of the right hand for last 13 years, with recent aggrevation. And clinically palpated thickened sausage like mass in right distal forearm and palm mainly at the thenar eminence. Most part of redundant tumor tissus was excised, and complete excision of the transverse carpal ligament for release of compression and adhesiolysis was performed with relief of the symptoms.

237 patients with Legg-Calve-Perthes disease were treated during past 12 years. Among them, a comparative study was done for 87 patients who were followed up over 2 years. They were analyzed according to Catteralls classification and divided into a group of conservative treatment and of surgical treatment. 74 patients were boys and 13 patients were girls and the ratio of boys to girls was 5.7 to 1. The mean age was about 6.9-year-old. Bilateral involvement was observed in 6 patients. According to Catterall classification. 1(1.1%) was classified as group I, 27(29.0%) as group II, and 36(38.7%) as group III, and 29(31.2%) as group IV. According to assessment by Harrison et al., satisfactory result was achieved in 63.2% of cases of conservative treatment and 34.3% of cases of operative treatment. The measurement of epiphyseal quotient and femoral head sphericity(by Mose) were considered meaningful methods for assessing the result of the treatment. The most frequent one of “Head-at-Risk” factors was lateral subluxation of femoral head. The result of treatment was not always coincided with the classification by Catterall. In bilateral involvement, the first affected hip had better prognosis than contralateral one.

This study intended to obtain an useful information on the prevalence of subjective symptoms, and to clarify the interrelationships between blood lead and lead related symptoms in low level lead exposure. The 93 male workers exposed to lead and 56 male nonexposed workers were examined for their blood lead (PBB), Zinc-protoporphy (ZPP), hemoglobin (HB) and personal history, and completed 15 questionnaires related to symptoms of lead absorption; also measured lead concentration in air (PBA) in the workplace. The results obtained were as follow; 1. The means of blood lead (PBB), blood ZPP and hemoglobin (HB) among workers exposed to lead were 26.1+/-8.8 microgram/dl, 28.3+/-26.0 microgram/dl and 16.2+/-1.2g/dl; whereas those of nonexposed workers were 18.7+/-5.1 microgram/dl, 20.6+/-8.7 microgram/dl and 17.3+/-1.1g/dl. The means of above three indicies between two groups showed significant difference statistically (p<0.05). 2. The means of blood lead (PBB), blood ZPP and hemoglobin of workers exposed to different lead concentration in air were as follows; When it was below 25 microgram/m3 , the indices were 24.7+/-79, 26.1+/-26.8 microgram/dl and 16.4+/-1.1 g/dl respectively; These indices were 27.1+/-8.5, 23.9+/-10.92 /dl and 16.2+/-1.3 g/dl when the lead concentration in air was 25~50 microgram/m3; and they were 3.4+/-9.3, 42.3+/-31.3 microgram/dl and 15.5+/-1.2 g/dl when the concentration of lead was above 50 microgram/m3. Although there were statistical difference in blood lead and hemoglobin among three different lead concentration in air, there was no statistical difference of blood ZPP among the three groups with different exposure levels (p>0.05). 3. The most frequently by complained symptom was "Generalized weakness and fatigue", and fewest symptom was "Intermittent pains in abdomen". 4. Only two symptoms out of fifteen symptoms checked by themselves revealed significant difference between exposed and nonexposed groups. These were "Intermittent pains of abdomen" and "Joint pain or arthralgia" (p<0.05). No positive correlation was found between the levels of blood lead and symptom groups categorized as gastrointestinal, neuromuscular and constitutional symptoms. 5. Blood lead (r=0.3995) and ZPP (r=0.2837) showed statistically significant correlation with mean lead concentration in air, whereas correlations were not demonstrated between blood lead and lead related symptoms or blood ZPP and lead related symptoms. 6. Blood lead (PBB) and ZPP showed association (r=0.2466) and the equation PBB=23.75+0.0842 ZPP was derived. 7. On stepwise multiple regression, using blood lead level as a dependent variable and ZPP, hemoglobin (HB), age, work duration (WD) and symptom prevalence as a independent variables, only ZPP significantly contributed a lot to blood lead level. 8. While the ZPP measurement was found to be a good indicator in evaluating health effect of lead absorption in low level lead exposure, lead related symptoms were not sensitive enough to evaluate of lead absorption in low level exposure.

A successful prosthesis is difficult to produce without using the implants in the severely resorbed alveolar ridges and maxillofacial defects. This report describes clinical experience of the overdenture using O-ring attachment. Clinical results have revealed successful application for the O-ring attachment in the two edentulous patients and a partial maxillectomy patient.

BACKGROUND AND OBJECTIVES: As mitral stenosis worsens, the cardiac output can be reduced, with a compensatory increase in the sympathetic nervous activity. An accelerated sympathetic nervous activity is responsible for various pathophysiological changes, including atrial thrombus formation, pulmonary congestion and myocardial ischemia. In this study, the sympathetic nervous activity was evaluated in patients with rheumatic mitral valvular stenosis, both before and after a percutaneous mitral balloon valvuloplasty (PMV). SUBJECTS AND METHODS: A PMV was successfully performed in 19 patients with mitral stenosis. The hemodynamic data were obtained by Swan-Ganz catheterization, and the variability in the heart rate evaluated by time domain measure via 24-hour ECG monitoring. An exercise test was performed according to Chung's exercise protocol, with the plasma norepinephrine level obtained before, during and after exercise. RESULTS: After the PMV, the right ventricle systolic, mean pulmonary arterial, pulmonary capillary wedge and left atrial pressures were significantly decreased. However, there were no significant changes in the right atrial, right ventricle end-diastolic and left ventricle end-diastolic pressures. After the PMV, the plasma norepinephrine level, an indicator of the sympathetic activity, was significantly decreased. On the other hand, the variability in heart rate, indicator of parasympathetic activity, was significantly decreased. CONCLUSION: In patients with mitral valvular stenosis, the sympathetic activity is accelerated, while the parasympathetic activity is decreased. This situation can be immediately reversed after a successful PMV.

OBJECTIVES: Demands for comprehensive and intensive treatment programs for treatment of children with attention-deficit hyperactivity disorder (ADHD) who suffer from serious impairment in various psychosocial areas are increasing. The aim of this study was to evaluate the possibility of developing new types of camp programs focused on improving social adjustment of children and helping parents effectively manage their children's problem behaviors. METHODS: Fifteen children diagnosed as ADHD according to Diagnostic and Statistical Manual of Mental Disorders-IV (mean age 9.5 years) and their parents participated in this program. Eight consecutive camps were held at two-week intervals, from Jun 2007 to Oct 2007 in an adolescent training center located at Chungtaesan, in Korea. Each camp program included social skills training in the classroom and outdoor activities in the forest for children, as well as parent training for mothers. In addition, after the sixth camp, we conducted one parental session for fathers and a three-day booster family camp three months later. Finally, eleven families adhered to the program. RESULTS: All children, parents, and therapists rated questionnaires or checklists at baseline, intra-, and post-treatment. Parenting burden rated using the Parenting Stress Index showed a significant decrease, from 57.89 to 46.22 (p=.019). And, overprotection rated using the Parenting Bonding Instrument showed a significant decrease, from 16.56 to 12.44 (p=.046). However, no significant improvement in children's behavioral and emotional problems was observed. CONCLUSION: In this study, the consecutive ADHD family camp program was effective for empowerment of parental competency, but not for general improvement of children's behavioral and emotional symptoms.
