The provision of adequate soft tissue cover for a complex hand and forearm wound-dirty, infected and exposed bone can be a challenging problem. Conventionally, a distant flap or free flap have been used, but these have been associated with several problems such as joint stiffness, risk of microsurgical procedures, negligible donor site morbidity, prolonged operation time and economic restriction. As well, fasciocutaneous flap has been the limitation of infection control. In these situations, the ipsilateral muscle flap provides the ideal cover with its rich blood supply and single operative field. Previously described by Lendrum(1980), by Lae et al.(1981), and later by McGeorge(1991), the brachioradilis muscle is the most superficial muscle on the radial side of the forearm. Its flap is based on the radial artery and venae comitantes. From August 1996 to October 1997, we performed branchioradialis muscle flap in seven patients. Despite the sacrifice of the major hand artery, brachioradialis muscle flap has many advantages including the reliability of flap survival, easy dissection, early mobilization and absence of functional and aesthetic problems at the donor site. It is a relatively simple and rapid method for resurfacing soft tissue defect in the hand and forearm. We obtained satisfactory and reliable results.

BACKGROUND: The combination of Philadelphia chromosome (Ph) and monosomy 7(-7) was rarely observed in acute lymphoblastic leukemia (ALL). With the results from immunophenotyplc and molecular analysis, Philadelphia chromosome positive ALL with monosomy 7[Ph(+)/-7] has been considered that it may be derived from neoplastic transformation at the pluripotent stem cell level. We compared the clini-cal, laboratory, and hematological findings between 5 cases of Ph(+)/-7 and 5 cases of Ph(+) without monosomy 7 [Ph (+) /N7]. METHODS: During the period from January, 1995 to December, 1996, total 72 cases of ALL were confirmed among 259 cases of hematologic malignancy with bone marrow cytogenetic analysis. Among 72 ALL cases, 5 cases of Ph(+)/-7(monosomy 7 or 7q abnormalities) were compared with Ph only or Ph without monosomy 7(ph(+)/N7] on the hematological, immunophenotypic, other laboratory, clinical findings and event ree survival (EFS) The karyotyping of the bone marrow specimens was analysed byshort-term unsynchronized culture methods such as overnight colcemid treatment and 24 hours incubation following ethidium bromide treatment. RESULTS: The mean age of Ph(+)/-7 was 30.6+/-12.8 years, and it was significantly different from that of Ph(+)/N7 (p=0.009), Four cases of Ph(+)/-7 were classified as ALL L2 subtype, and 2 cases revealed CNS involvements. Immunophenotyping was positive in CD10, CDl9, CD2O, CD22 and HLA-DR. But one case revealed e-B-lymphoid lineage with positivity in CD34, CDl3, and CD33. The response to chemotherapy and EFS was very poor in Ph(+)/-7 group, and the mean EFS was 3.2+/-1.9 months(p=0.014). All of cases showed induction on failure in chemotherapy, relapsed with bone marrow, CNS and extramedullary involvements, and expired due to sepsis. CONCLUSIONS: Ph(+)/-7 ALL had very Poor clinical course with being resistant to chemotherapy and unfavorable prognosis, revealed L2 subtype by FAB classification, and was slightly older in ages compared with Ph(+)/N7 ALL.

In male reproducible health, fertility and IVF (in-vitro fertilization), semen analysis has been most important. Semen analysis can be divided into concentration, motional and morphological analysis of sperm. The existing method which was developed earlier to analyze semen concentrated on the sperm motility analysis. To provide more useful and precise solutions for clinical problems such as infertility, semen analysis must include sperm morphological analysis. But the traditional tools for semen analysis are subjective, imprecise, inaccurate, difficult to standardize, and difficult to reproduce. Therefore, with the help of development of microcomputers and image processing techniques, we developed a new sperm morphology analyzer to overcome these problems. In this study the agreement on percent normal morphology was studied between different observers and a computerized sperm morphology analyzer on a slide-by-slide basis using strict criteria. Slides from 30 different patients from the SNUH andrology laboratory were selected randomly. Microscopic fields and sperm cells were chosen randomly and percent normal morphology was recorded. The ability of sperm morphology analyzer to repeat the same reading for normal and abnormal cells was studied. The results showed that there was no significant bias between two experienced observers. The limits of agreement were 4.1%~-3.8%. The Pearson correlation coefficient between readers was 0.79. Between the manual and sperm morphology analyzer, the same findings were reported. In this experiments the slides were stained by two different methods, PAP and Diff-Quik staining methods. The limits of agreement were 7.2%~-5.7% and 6.0%~-6.3%, respectively. The Pearson correlation coefficients ware 0.76 and 0.91, respectively. The limits of agreement was tighter below 20% normal forms. In the experiments of repeatability, 52 cells stained by PAP and Diff-Quik staining methods were analyzed three times in succession. Estimating pairwise agreement, the kappa statistic for the pairs were 0.76, 0.81, 0.86, and 0.75, 0.88, 0.88 respectively. In this study it was shown that there was good agreement between manual and computerized assessment of normal and abnormal cells. The repeatability and agreement per slide of computerized sperm morphology analyzer was excellent. The computer's ability to classify normal morphology per slide is promising. Based on results obtained, this system can be of clinical value both in andrology laboratories and IVF units.

PURPOSE: Neonatal seizures are mostly symptomatic and have variable atypical clinical features with very different EEG findings from those of post-neonatal period. This study was performed to determine the common types of epileptiform discharges and their relationship with abnormalities in imaging study in neonates with seizures. METHODS: Fourty one neonates under 7 days of age who had been hospitalized at the Hanyang university hospital from June 1993 to May 1997 were studied retrospectively. Their medical records, results of EEG and brain imaging study were reviewed. RESULTS: 1) The types of neonatal seizures were subtle, generalized tonic, multifocal clonic, focal clonic, myoclonic in order of frequency. 2) The most common epileptiform discharge was excessive sharp transients recorded in 28 cases and the rest showed multifocal spikes, sharp waves, repetitive alpha, repetitive theta in order. Epileptiform discharges appeared on the both hemisphere in 24 cases, right hemisphere in 9 cases and left hemisphere in 8 cases. 3) Imaging study showed no abnormal findings in 27 cases and abnormal findings in 14 cases such as brain edema, intracranial hemorrhage, leukomalacia, subarachnoid hemorrhage, cephalhematoma, craniosynostosis. 4) Among 14 cases with radiological abnormalities, 5 cases had localized abnormalities and 3 of them had the abnormal EEG discharges on the same area concomittantly. But in total only 3 cases of 17 cases with localized epileptiform discharges had abnormalities in imaging study on the same site and so significant relationship between two studies was not observed. 5) As for the prognosis of seizures, subsided in 23 cases without any antiepileptic drugs, 13 cases had no seizure after taking medicine for few days and 5 cases needed continuous antiepileptic drug. CONCLUSION: This study showed no meaningful relationship between abnormal EEG findings and localization by imaging study in neonatal seizure but we concluded that brain imaging study was needed to determine degree of encephalopathy in neonatal seizures.

The purpose of the present study lied in examining the incidence, treatment and failure causes of peri-implantitis by analyzing medical charts of those patients who underwent implant placement for the past 2 years. The subjects included those patients who underwent implant placement at the present hospital from January 2001 to December 2002. 3i implants were used for the analysis for the comparison of significance. A total of 301 patients were examined, among whom 102 were females and 199, males. Implants were placed in a total of 578 cases. The number of peri-implantitis was present in a total of 29 cases (21 males and 8 females), giving the incidence at 9.6%. The evidence of peri-implantitis was seen in 60 cases, which was in 10.4% of the patients. Among those cases with peri-implantitis, 28 cases (47%) underwent bone graft and 22 cases (43%) underwent maxillary sinus lift. Furthermore, 4 of these patients had systemic diseases such as diabetes or hypertension. Regular management is important for the preven ion of peri-implantitis. In other words, early prevention through regular follow-ups to check the status of surrounding soft tissue would be needed to maintain implants.
