Argon laser trabeculoplasty(ALT) is commonly used in the treatment of uncontrolled open angle glaucoma. The authors retrospectively reviewed the efficacy of ALT in 52 patients(57 eyes) with primary open angle glaucoma. The mean follow-up was 28 months(range 2-48 months). The decrease in intraocular pressure 10P) was 10.1 +/- 3.5 mmHg at 1 month, 8.2 +/- 2.8 mmHg at 1 year, 6.2 +/- 5.1 mmHg at 2 years and 51% at 3 years. Failure was most common in the first 6 months after treatment(29%) and thereafter failure occurred at a rate of 5% to 15% per year. The sex and age of patients had no significant effect on success rate. The success rate was high in the patients with baseline IOP of 26 to 30 mmHg. A mild iritis in all cases, transient rise in IOP, peripheral anterior synechia and microscopic hyphema were noted as early complications of ALT.

Transforming growth factor (TGF)-beta1 plays an important role in hepatocarcinogenesis and has been described as a useful tumor marker and one of the poor prognostic indicators in patients with hepatocellular carcinoma (HCC). To investigate the role and cellular localization of TGF-beta1 during multistep hepatocarcinogenesis we performed a quantitative analysis of TGF-beta1 mRNA and immunohistochemical expression of TGF-beta1 and TGF-beta receptor II (TGF-betarII) in female Sprague-Dawley rats. The experimental groups included neoplastic lesions produced by Solt-Farber's protocol, regenerating liver after partial hepatectomy, and normal control. Quantitative change of TGF-beta1 mRNA was analysed by competitive reverse-transcription polymerase chain reaction (RT-PCR). TGF-beta1 protein and TGF-betarII expression were evaluated by immunohistochemical stain. The discrete tumor nodules were detected on 14th day and then increased in number and size. Three HCCs were induced on 8th or 9th month. RT-PCR demonstrated TGF-beta1 mRNA band in all examples of the normal and regenerating liver, nodules and HCCs. Competitive RT-PCR displayed higher TGF-beta1 mRNA in nodules, HCCs and regenerating liver than in normal controls. Hepatocytes from control and regenerating livers showed weak immunoreactivity for TGF-beta1. In contrast, the cytoplasm of hepatocytes of nodules in 7th, 8th and 9th month and HCCs were intensely stained for TGF-beta1. Some sinusoidal cells showed immunoreactivity for TGF-beta1 in all experimental groups. In early phase of carcinogenesis, the cytoplasm of hepatocytes in liver of 12h, 1d and 3d showed transiently increased immunoreactivity for TGF-beta1 and The immunoreactivity decreased thereafter. TGF-beta1 mRNA was also detected in the neoplastic hepatocytes by in-situ hybridization. Although TGF-betarII expression was correlated with TGF-beta1 immunoreactivity during early phase of carcinogenesis, hepatocytes in most nodules in 7th, 8th, 9th month and carcinomas showed decreased or little immunoreactivity for TGF-betarII. Based on the above results, it is concluded that TGF-beta1 expression increases not only in precancerous nodules but also in HCCs and its increase seems to be correlated with decrease or loss of TGF-betarII expression although its mechanism remains unclear. Hepatocytes may be a major cellular source of TGF-beta1 during hepatocarcinogenesis.

INTRODUCTION: The objective of the present study was to investigate the independent effects of major depressive disorder (MDD) and insomnia on somatization, respectively. METHODS: A total of 181 participants (73 males and 108 females ; mean age 41.59+/-8.92) without serious medical problem were recruited from a community and a psychiatric clinic in Republic of Korea. Subjects were divided into 4 groups based on the Structured Clinical Interview for DSM-IV axis I disorder (SCID-IV) and sleep questionnaire : 1) normal controls (n=127), 2) primary insomnia (n=11), 3) MDD without insomnia (n=14), and 4) MDD with insomnia (n=29). All participants were requested to complete the somatization subscores of the Symptom Checklist-90-Revised (SCL-90-R). RESULTS: There were significant between-group differences in somatization score (F=25.30, p<0.001). Subjects with both MDD and insomnia showed higher somatization score compared to normal control (p<0.001), subjects with primary insomnia (p=0.01), or MDD subjects without insomnia (p<0.001). Subjects with primary insomnia had higher somatization score than normal controls (p<0.01), while there was no significant difference between MDD subjects without insomnia and normal controls. In multiple regression, presence of insomnia predicted higher somatization score (beta=0.44, p<0.001), while there was only non-significant association between MDD and somatization (beta=0.14, p=0.08). CONCLUSION: In the current study, insomnia was associated with somatization independently from major depression. Subjects with primary insomnia showed higher somatization. Within MDD patients, presence of insomnia was related to higher somatization. Our finding suggests that insomnia may partly mediate the relationship between depression and somatization.

BACKGROUND: A novel technique for the repair of tears of the upper subscapularis tendon—intraarticular knotless fixation—has been introduced recently. The purpose of this study was to evaluate the clinical and structural outcomes of arthroscopic intraarticular knotless fixation for the treatment of upper subscapularis tendon tears. METHODS: We retrospectively analyzed the clinical and radiological outcomes of 27 patients who underwent arthroscopic intraarticular knotless fixation for upper subscapularis tendon tears. Finally, a total of 10 patients who could participate in at least a 6 month follow-up of magnetic resonance imaging evaluation and in a least 1-year follow-up on an outpatient basis were enrolled in our study. The mean age at the time of operation was 60.7 years, and the mean duration of follow-up was 14.7 months. Two patients had concomitant tears of the supraspinatus tendon and 8 patients had concomitant tears of the supraspinatus and the infraspinatus tendons. RESULTS: The clinical and radiological outcomes improved after the patients had undertaken arthroscopic intraarticular knotless fixation. The mean visual analogue scale score for pain during motion improved from 6.7 preoperatively to 1.4 at the final follow-up (p<0.001). The mean Constant score improved from 59.3 preoperatively to 79.6 at the final follow-up, and the mean the University of California at Los Angeles score, from 21.7 to 30.2, respectively (p<0.001 and p<0.001). The upper subscapularis tendon tear was healed in every patient except one (90%), for the patient had suffered from a postoperative trauma that resulted in a retear. CONCLUSIONS: We found that arthroscopic intraarticular knotless fixation gives good clinical and structural outcomes for the repair of upper subscapularis tendon tears. Arthroscopic intraarticular knotless fixation provided such a reliable and efficient restoration of the subscapularis tendon footprint that we anticipate it will become a widely-used procedure for upper subscapularis tendon tears.

Poor marginal fidelity resulting in a large marginal gap increases plaque accumulation, gingival inflammation and dental caries. The purpose of this study was to evaluate the marginal fit of three different cervical finishing methods of prepared teeth. A stereomicroscope was used to measure the space between the margin of restoration and the finishing line of prepared tooth. The results were statistically analyzed using the ANOVA and Multiple Range Test(Tukey`s HSD). The results were as follows : 1. There were no significant differences concerning the types of tooth and position (P<0.05),whereas the differences were statistically significant in case of cervical finishing methods (P<0.05). 2. There were statistically significant differences between before and after cementation (P<0.05). 3. In comparison according to variable margin after cementation, the gap discrepancies were increased in 130degreeshoulder margin, chamfer margin and 90degreeshoulder margin in ascending order, and there were significant differences between 90degreeshoulder margin and chamfer, 130degreeshoulder margin 4. In comparison according to variable margins, the gap discrepancies were increased in chamfer margin, 130degreeshoulder margin and 90degreeshoulder margin in ascending order, and there were significant differences between 90degreeshoulder margin and chamfer, 130degreeshoulder margin 5. This study demonstrated a better marginal fit with all-ceramic crowns fabricated on chamfer and 130degreeshoulder margin compared with 90degreeshoulder margin.

A 45-Year-old para 1-0-1-1 had submucosal myoma diagnosed by ultrasonogram and hysteroscopic examination. During 60 minutes hysteroscopic myomectomy, 8,000 ml of sorbitol-mannitol distention medium was used and 6,500 ml collected, resulting in a deficit of 1,500 ml. The patient received Ringer`s lactate 1,000 ml intravenously. Her urine output was 400 ml. Blood loss was 40 ml. After operation, hyponatremia(115 mEq/L) was developed and pulmonary edema was also diagnosed clinically at that time and later confirmed by chest radiograph. The judicious administration of diuretics and normal saline fluid replacement to prevent overcorrection to hypernatremia resulted in return of serum electrolytes to normal level and resolution of the pulmonary edema by postoperative day 1. We have experienced a case of pulmonary edema during hysteroscopic myomectomy with sorbitol-mannitol distention medium, which is presented with a brief review of literatures.

Subtrochanteric fractures of the femur are difficult to manage successfully. Two factors, involvement of cortical bone tissue and concentration of stress, frequently have been mentioned as reasons for the high incidence of failure in the treatment of these fractures. We studied 37 patients with 38 subtrochanteric fractures treated at the Seoul Red Cross Hospital from Feb. 1978 to Nov. 1983. The results were obtained as follows: 1. Of the 37 patients studied, 29 were male and 8 female. The majority of male patients (representing 62.1%) were between 21 and 50 years of age, while 7 of 8 female patients were after 50years of age. 2. In 27 (73.0%) of our patients, the fracture resulted from high-energy trauma, traffic accident or fall from height. 3. Many fractures in the present series could not be classified in the manners described by Fielding, Zickel or Seinsheimer. So, we could not find any correlation between fracture type and used fixation device or its prognosis. 4. The associated injuries, which were relatively common in lower limb (10 cases) and pelvis (8 cases), made the fractures more difficult to treat. 5. Of the 38 fractures, 35 (92.1%) were treated by operative means. The Jewett nail was the device most commonly used, with a total of 11(31.4%) fractures being so treated. 6. The average time from operation to partial weight bearing was 12.9 weeks. 7. The average time untill clinical union was about 14 weeks and radiographic union about 24 weeks. 8. From these series, it was considered that, although early weight bearing is frequently impossihle, Jewett nail, plate and screw, compression hip screw, Judet plate or blade plate can be applied successfully to the treatment of subtrochanteric fractures of the femur if the most proper one which can stabilize the lesion effectively is selected and weight bearing is delayed for a sufficient period.
