Finger injuries are becoming more common with the increasing use of mechanical industrial and household appliances. Among the hand injuries, amputation is the serious disaster to the patient. Recently, application of microsurgical technique to the reattachment of amputated digits has been common clinical procedures. We performed microsurgical replantation to the 75 patients with 102 digits from March in 1986 to February in 1988. The following results were obtained. 1. The most common age distribution was third decade and male to female ratio was about 5:1. 2. The ratio of right to left hand was about 1:1 but the dominant to non-dominant hand was about 2:1. 3. The index finger was most commonly injured and the next was middle finger. 4. The most common type of the injuries was the crushing injury and the most common vector was a kind of pressor. 5. The anesthesia was performed in equal ratio between the general and regional anesthesia. 6. The survival rate of micro-replantation to the injuries of the zone II was 77.8% and zone III was 80%. 7. The functional result after replantation at zone II was better than zone III. 8. Micro-replantation was performed in any case of the type of the injury, the severity of crushing and the ischemic time, and the patients requirement was an important factor.

In two female siblings, growth and developmental retardation, poor sucking, anorexia, floppiness and respiratory difficulty developed around 2 and 4 monthes of age in each, and the respiratory symptoms rapidly aggravated to comatose states and finally into death one month later. On admission at emergency room, severe acidosis and high lactate and pyruvate levels in serum and cerebrospinal fluid were revealed in one. Brain computed tomography and magnetic resonance imaging revealed identical bilateral involvement of putamen in both of the sibs, which made the diagnosis of Leigh disease(subacute necrotizing encephalomyelopathy) possible. There is also a family history of early death in infancy period; an elder sister and a brother of mother died with unknown cause at their 5 and 10 months of age. Mitochondrial enzyme functions could not be assayed.

To evaluate the efficacy of amniotic membrane in the management of painful bullous keratopathy secondary to the intractable glaucoma and in preventing exposure of drainage devices, we inserted Ahmed valve with amniotic membrane patch graft over the implant itself, and debrided corneal epithelium with amniotic membrane graft over the exposed stroma as a single operation. During the follow-up periods, we monitored vision, intraocular pressure (IOP), presence of ocular pain, and postoperative complications associated with the implants. The mean follow up period was 8.4+/-3.2 months. IOP was well controlled after the intervention. The preoperative mean IOP was measured as 43.9+/-9.0 mmHg and lowered to 16.1+/-1.8 mmHg at the last visit and no complications associated with the implants were noted. Even though the improvement in vision was not prominent, the ocular surface stabilized rapidly and ocular pain associated with bullous keratopathy disappeared soon after surgery. Conclusively the use of amniotic membrane in conjunction with Ahmed valve implantation is an effective way to relieve ocular pain and lessen the chances of complications associated with the implant in patients with intractable glaucoma and bullous keratopathy.

Cancer screening evaluation will be a important issue in Korea in near future. Bias in cancer screening evaluation is well known by concept, but it is not applied yet using the data from screening program of Korea. So introducing the way how the bias is adjusted will be helpful. This review deals with the type, meaning, the way how the bias is adjusted, and examples. Especially, lead-time bias, length bias and self-selection bias were focused. Adjusting bias is one of the imperative step for epidemiologic analysis. Understanding the background concept and experience using the screening program data will be helpful for estimating the effectiveness of national screening program of Korea.

OBJECTIVES: Tardive dyskinesia(TD) is a serious side effect associated with long-term antipsychotic treatments. Some candidate genetic polymorphisms were reported to be associated with TD and possible involvement of serotonergic receptors in the pathophysiology of TD has been suggested. In the present study, we investigated the association between 5-HT6 receptor gene polymorphism and TD with schizophrenia. METHODS: To investigate the relationship between 5-HT6 receptor gene polymorphism and TD, 60 patients with TD were compared with 60 patients without TD. The 267C/T allele of 5-HT6 receptor gene was genotyped by means of polymerase chain reaction method. TD was evaluated using the Abnormal Involuntary Movement Scale(AIMS). RESULTS: The patients with the three 267C/T genotype showed no significant differences in age, gender, and duration of illness. No significant difference in genotype frequencies was observed between schizophrenic patients with and without TD. In addition, there was no difference in allele frequencies. Further analysis with an measure of AIMS scores showed that these scores were not significantly influenced by the 5-HT6 receptor gene polymorphism. CONCLUSION: These results suggest that 267C/T polymorphism of 5-HT6 receptor gene is not significantly associated with susceptibility to TD in schizophrenia.
