Between 1984 and 1996, 8 patients who were suffered from stage g Kienbock's disease underwent interpositional arthroplasty using pronator quadratus pedicled bone. Patients comprised 2 males and 6 females, with an average age of 33 years(range 19-47). Range of motion of the wrist, residual pain, grip strength, and carpal height ratio of the patients were analyzed. The follow-up period was between 1.5 years and 12.5 years(average 5.5 years). The arc of flexion-extension of the wrist was increased from average 74 degrees preoperatively to 96 degrees postoperatively. Among eight patients, five were free of pain and three had intermittent pain during heavy work. None of eight patients had any discomfort in daily work and changed his or her occupation. The grip strength was average 83% of the normal side. Carpal height ratio was average 0.48 preoperatively and was not changed postoperatively. Clinical results, assessed by Lichtman-Evans criteria, showed 4 good and 4 fair. The interpositional arthroplasty using pronator quadratus pedicled bone was considered as a very effective method for the treatment of stage III Kienbock's disease.

We investigated population densities of mosquitoes infected with sporozoites in three highly epidemic areas of Josan-ri and Jangpa-ri (Paju City) and Dongjung-ri (Yeoncheon County) in Korea. Anopheline mosquitoes were collected from both indoors and outdoors by human baiting collection method during the period of the first week of June to the second week of September 1999. Total 13,296 female mosquitoes were collected and 8,650 (65.1%) were Anophelines. Thirty seven percent (3,199) of the Anopheline mosquitoes were captured outdoors and 63.9% (5,531) indoors. Employing a sandwich enzyme-linked immunosorbent assay (ELISA), we analyzed a total of 7,820 Anopheline mosquitoes and found that 7 Anopheline mosquitoes were infected with sporozoites. The positive rate in Josan-ri was 0.14% (5/3,500) and 0.15% (2/1,370) in Jangpa-ri. The total positive rate in all three surveyed areas was 0.09% (7/7,820). The mosquitoes infected with the sporozoites were detected on June 28th (n=2), July 5th (n=1), July 19th (n=1), August 9th (n=1), September 6th (n=1), and the last one on September 13th (n=1). They were all classified as Anopheles sinensis, which showed positive reaction in ELISA test. Therefore it might be concluded that A. sinensis plays an important role in re-emerging malaria transmission in Korea.

OBJECTIVES: We studied the circadian rhythm of nonlinear heart rate dynamics in healthy subjects. BACKGROUND: The frequency of sudden cardiac death increases in the morning. The relationship between decreased complexity of heart rate dynamics and sudden cardiac death has been documented. An understanding of the circadian variation in the complexity of cardiac dynamics may be important and to predict and prevent this sudden cardiac death. METHODS: Dynamic 24-hour electrocardiographic recordings were obtained from 30 healthy ambulant subjects aged 41 to 50 years and the digitized data was partitioned into sections of 30 minutes' duration. For each section, four indexes obtained from separate algorithms of nonlinear dynamics of RR interval - correlation dimension, Lyapunov exponent, approximate entropy, and fractal dimension - were calculated. Normalized low- (0.04-0.1 hertz) and high-frequency (>0.15 hertz) components were also calculated. RESULTS: All the four indexes of nonlinear dynamics showed a remarkably similar circadian rhythm: a prominent morning dip preceded by a steep decline during the late night, a recovery during the evening and a peak around midnight. In the morning, the low frequency component rose rapidly with concomitant withdrawal of the high frequency component. CONCLUSION: The complexity of cardiac dynamics decreases significantly in the morning, and this may contribute to the ominously increased rate of cardiac death in the morning hours.

Thyroid storm (thyrotoxicosis) is rarely encountered during pregnancy or the puerperium, even in untreated women and characterized by hypertension, hyperthermia, and multiple systems involvement. Much more common is heart failure, apparently caused by the long-term myocardial effects of thyroid hormone and intensified by other pregnancy complications that include severe preeclampsia, infection, anemia, or combinations of these. Prompt diagnosis and treatment of thyroid storm are essential in reducing morbidity and mortality of a patient from this disorder. We experienced a case of triiodothyroxine induced thyroid storm (T3 thyrotoxicosis) developed after Cesarean section. This case highlights both physicians should be aware of the symptoms and risk factors and reversing of heart failure successfully by reducing cardiac workload is important through immediate medical treatment - adequate hydration, thermoregulation, and control of hypertension, infection and anemia et al.

BACKGROUND: Several studies have shown that the presence of cerebrovascular lesions may play an important role for determining the severity of the clinical symptoms of dementia. But no study to date has explored the clinical effect of cerebrovascular disease in Parkinson's disease with dementia (PDD), although cerebrovascular disease is common causes of dementia in elderly population. Therefore we conducted this study to evaluate the relationship between silent cerebrovascular lesions and cognitive decline in PDD. METHODS: Only 27 patients with PDD were chosen; 17 patients had PDD with silent cerebral ischemic lesions (PDDI) and 10 patients had PDD without silent cerebral ischemic lesions (pure PDD). These subjects received the global cognitive function testing and were all evaluated with detailed neuropsychological tests including attention, memory, language, and also the visuospatial and frontal function. RESULTS: There were no significant differences between pure PDD and PDDI group on general cognitive functions tests. Regard to mean time duration of suffering from Parkinson motor symptoms and motor function scale, pure PDD group showed more long duration than PDDI group but there was no significant difference between two groups. Furthermore, there were not any significant differences between the two groups on detailed neuropsychological tests. CONCLUSIONS: We concluded that silent cerebrovascular lesions do not contribute to neuropsychological severity of PDD, although vascular disease is a common cause of cognitive impairment in the elderly. Thus the results of the present study suggest that factors other than cerebrovascular disease contribute to severity of PDD.

PURPOSE: The purposes of this study were to investigate the expression pattern of pro-inflammatory cytokines during distraction osteogenesis and to compare these with expression during simple fracture healing. MATERIALS AND METHODS: Regenerated bones from the rat tibia subjected distraction osteogenesis and simple fracture healing models were harvested over three-week periods. Temporal expressions of mRNA of pro-inflammatory cytokines were investigated by RNase protection assay. Immunohistochemical studies for IL-6 were performed in postoperative day 7 and 9 tissue section specimens. RESULTS: IL-1beta and IL-6 produced detectable signals, while IL-1alpha, TNFalpha and TNFbeta did not. The mRNA expressions of IL-1beta and IL-6 were markedly upregulated on postoperative day 1 and then subsided to the preoperative level. IL-1beta mRNA expression remained the same even when distraction began. However, IL-6 mRNA expression was reactivated during the distraction phase. Immunohistochemical study revealed the expressions of IL-6 not only at the transitional zone of the transchondroid ossification, in young osteoblasts lining newly formed trabeculae and in hematopoietic cells in the marrow but also in primitive mesenchymal cells at the distraction gap. CONCLUSIONS: Distraction strain re-induced IL-6 expression during distraction osteogenesis, which suggests that well-controlled inflammatory reaction might contribute to active new bone formation in distraction osteogenesis.

BACKGROUND/AIMS: This study was designed to evaluate normal Korean pancreaticobiliary ducts and to assess the prevalence and pattern of variations and anomalies of theses structures. METHODS: We performed this multicenter study in which 7 university hospitals in Korea participated from March 1997 until June 1999. Total 10,243 ERCP cases were reviewed during this study period. RESULTS: 1) Maximal and midportion diameters of common bile ducts were 6.4+/-1.8 mm and 5.5+/-1.7 mm, respectively. Maximal and midportion diameters of pancreas head were 3.2+/-1.1 mm and 2.7+/-1.0 mm, respectively. Pancreaticobiliary duct diameters of subjects above the age of 40 were greater than those of subjects below the age of 40 (p<0.05). 2) The prevalence of choledochal cyst was 0.32%. The prevalence of gallbladder anomalies and anomalous union of pancreaticobiliary duct was 4.2% and 4.1%, respectively. The prevalence of pancreas divisum and annular pancreas was 0.49% and 0.05%, respectively. The most common type of pancreaticobiliary duct union was V shape (60.2%), followed by U shape (23.7%) and Y shape (16.1%). CONCLUSIONS: Understanding normal pancreaticobiliary structures and being aware of the prevalence and pattern of variations and anomalies of pancreaticobiliary structures will be helpful to diagnose and treat patients with pancreaticobiliary problems.
