Seventy-three uncemented total hip arthroplasties in the sixty-four patients were studied as a retrospective manner. Hydroxyapatite and tricalcium-phosphate (HA/TCP Calcicoat) coated titanium fiber-mesh stems were used in forty-eight cases and the identical components but without hydroxyapatite coating were used in the other twenty-five cases. The distribution of the patients in two groups showed no statistically significant differences and the same porous coated hemispherical acetabular components were used in two groups. At the time of two year follow-up after the operation, the mean Harris hip score and the Enghs radiographic assessment score were 95.5 and 19.8, respectively, in the HA/TCP Calcicoat tm group and 94.4 and 19.2, respectively, in the non-coated group. None of these differences were statistically significant. At three months after operation, the frequency of the thigh pain was 8.3% in the HA/TCP Calcicoat tm group and 20% in the non-coated group, which was also not significantly different (p=0.24). There were no revisions in either group. All the femoral components except one among the non-coated group showed stable bony fixation in both groups and no differences in Enghs radiographic assessment criteria were detected between the two groups. There seemed to be a tendency of early pain relief and more endosteal new bone formation in the HA/TCP Calcicoat TM group, which, however, failed to show a statistically significant clinical or radiographic differences. This result is considered as preliminary and longer follow-up should be required to uncover any hidden advantages or disadvantages of the HA/TCP Calcicoat TM coating on titanium fiber-mesh stem.

A clinical study was done on 42 cases of inpatients, who had been admitted for foreign body aspiration form January 1979 to June 1992. We obtained the following results by analysing the records of their treatment during that time. 1) 31(73.8%) of these cases were below the age of 3 years. 25(59.4%) were below the age of 2. The ratio of male to female was 2:1 2) In 23 cases(54.8%) onset of the symptoms and diagnosis was less than 24 hours after aspiration. 3) Most of the cases(83.3%) had a history of foreign body aspiration; 7 other cases did not. 4) The most common symptoms of bronchial foreign bodies were cough, dyspnea and fever, whereas those of laryngotracheal foreign bodies were dyspnea and cough, in that order. 5) Common complications were obstructive emphysema, pneumonia and atelectasis, in that order. These complications were observed more frequently in the cases of vegetable foreign bodies. 6) Chest X-ray at the time of admission showed obstructive emphysema (42.9%) and pneumonia(40.5%). 11 cases(26.2%) were normal. 7) The most comon site of foreign body enlodgement was the right main bronchus(38.1%), and 4 cases(9.5%) were discovered in other bronchial sites. 8) Vegetable foreign bodies occupied 54.8% of the cases, peanuts being the most common.

PURPOSE: This study was conducted to know the applications and limitations of three dimensional volume rendering virtual endoscopy of the ossicles using a multi-row detector CT. MATERIALS AND METHODS: This study examined 25 patients who underwent temporal bone CT using a 16-row detector CT as a result of hearing problems or trauma. The axial CT scan of the temporal bone was performed with a 0.6 mm collimation, and a reconstruction was carried out with a U70u Sharp of kernel value, a 1 mm thickness and 0.5-1.0 mm increments. After observing the ossicles in the axial and coronal images, virtual endoscopy was performed using a three dimensional volume rendering technique with a threshold value of -500 HU. The intra-operative otoendoscopy was performed in 12 ears, and was compared with the virtual endoscopy findings. RESULTS: Virtual endoscopy of the 29 ears without hearing problems demonstrated hypoplastic or an incomplete depiction of the stapes superstructures in 25 ears and a normal depiction in 4 ears. Virtual endoscopy of 21 ears with hearing problems demonstrated no ossicles in 1 ear, no malleus in 3 ears, a malleoincudal subluxation in 6 ears, a dysplastic incus in 5 ears, an incudostapedial subluxation in 9 ears, dysplastic stapes in 2 ears, a hypoplastic or incomplete depiction of the stapes in 16 ears and no stapes in 1 ear. In contrast to the intra-operative otoendoscopy, 8 out of 12 ears showed a hypoplastic or deformed stapes in the virtual endoscopy. CONCLUSION: Volume rendering virtual endoscopy using a multi-row detector CT is an excellent method for evaluation the ossicles in three dimension, even though the partial volume effect for the stapes superstructures needs to be considered.

OBJECTIVES: The purpose of this study was to evaluate the characteristics of personality factor and defense mechanism and relationship with depression and social disability. METHODS: Study subjects consisted of 35 panic disorder patients diagnosed with the criteria of DSM-IV. Data were collected through Sixteen Personality Factor Questionnaire, Ehwa Diagnostic Test of Defense Mechanism, Beck Depression Inventory and Sheehan Disability Scale. Statistics employed for the analyses were Pearson correlation and independent sample t-test. RESULTS: In personality factors and defense mechanisms, there were no definitely abnormal range of scores. But, among personality factors, tension/anxiety factor scored high and unstableness/stableness, shyness/boldness and praxernia/atunia were in low range of score. In defense mechanism, somaticzation and acting-out scored high and humor, suppression, altruism, avoidance and rationalization scored low. The mean BDI score was 18.25+/-9.97. The mean score of SDS were 4.88+/-3.11 in work category and 4.57+/-2.92 in social/leasure category. Male patients were significantly correlated with guit-proneness and atuia in personality factor and passive- aggressiveness, projection, denial and show-off in defense mechanism, compared with female patients (p<0.05). The patients' age was correlated with low intelligence in persolity factor and dissociation and anticipation in defense mechanism. It was negatively correlated with show-off (p<0.05). The BDI score was correlated with low intelligence, superego, unstableness, self-conflict, high superego and atunia in personality factor and dissociation and somatization in defense mechanism (p<0.05). There was a significant relationship between BDI score and SDS work category (p<0.05). CONCLUSION: Panic disorder patients show high score of tension/anxiety factor and they frequently use neurotic defense style like somatization. The depressive symptom, which depends on symptom severity, appears to have influence on work category and to cause social disability.

OBJECTIVE: Several lines of evidence suggest that brain-derived neurotrophic factor (BDNF) plays a role in the pathophysiology of anxiety. We analyzed the association of the BDNF gene polymorphism, G196A (val66met), in the coding region of exon XIIIA in chromosome 11p13, and generalized social anxiety disorder (GSAD). METHODS: Patients with GSAD (n=73) and age-matched control subjects (n=152) were tested for the BDNF (val66met) polymorphism. A clinical interview and a Mini-International Neuropsychiatric Interview were conducted by trained psychiatrists in order to diagnose GSAD. The symptomatic characteristics of the GSAD patients were assessed with the Hamilton Anxiety Rating Scale, the Beck Anxiety Inventory, the Retrospective Self Report of Inhibition, the Spielberger State-Trait Anxiety Inventory, and the Liebowitz Social Anxiety Scale. RESULTS: There were no significant differences in the frequencies of the genotypes (chi2=0.961, degree of freedom [df]=2, p=0.619), alleles (chi2=0.415, df=1, p=0.519), or allele (methionine) carriers (chi2=0.019, df=1, p=0.889) between the patients and controls. In addition, when we compared the severity of social anxiety symptom as determined by the clinical scales with the genotypes of the BDNF gene, we could not find any significant differences between the genotypes or allele carriers. CONCLUSION: These results do not support the hypothesis that the BDNF gene might be a candidate gene for susceptibility or severity of GSAD in the Korean population in this study.

Membranoproliferative glomerulonephritis type II(MPGN II), also called dense deposit disease, was first described by Berger and Galle in 1963. The diagnosis of MPGN II is based on electron-microscopic finding of an intensely electron-dense substance which replaces the lamina densa of the glomerular basement membrane. Although the etiology and pathogenesis of MPGN II are unknown, it frequently progresses to end-stage renal failure. Typically in MPGN II, hypocomplementemia due to activation of the alternative complement pathway is present. In addition, the association of MPGN II with partial lipodystrophy and complement abnormalities is well documented. The relationship between these associated features and the patient's renal functional outcome is not clear. With respect to the therapy for MPGN II, an alternate-day prednisolone regimen was shown to be effective. Various treatment modalities, including immunosuppression with corticosteroids, cytotoxic drugs and cyclosporin A, anticoagulants and antiplatelet therapies are used, either alone or in combination, with varying degrees of success. The purpose of this paper is to present a case of MPGN II from a 7 years old girl with paroxysmal supraventricular tachycardia(PSVT).
