Lumbosacral fracture-dislocation is very rare because of the characteristic anatomical features, and various displacements by injury mechanisms have been reported. Most of the reports were displaced by flexion, distraction, compression and rotation. Complete reduction and appropriate treatment can be difficult or impossible in the case of delayed diagnosis. We report a case of lumbosacral fracture & dislocation that occured in horizontal shear and flexion, which was correctly diagnosed and treated successfully with partial corpectomy, open reduction, posterior interbody fusion and transpedicular fixation with posterolateral fusion by posterior approach only.

Verapamil overdose results in cardiac arrhythmia including the complete A-V block, and hypotension due to decreased peripheral resistance and decreased myocardial contractility. However, sustained-release verapamil overdose frequently has atypical presentations, such as delayed and prolonged course of toxic signs and symptoms. Although several cases of sustained-release verapamil overdose have been reported worldwidely, the specific treatment modalities and prognostic indicators for verapamil overdose have not been well-defined. Recently, we experienced a case of sustained-release verapamil overdose in 30-year-old female. 10 hours after verapamil ingestion she presented in severe bradycardia and hypotensive shock state. Initial EKG showed the complete AV block and her systolic blood pressure was below 60 mmHg. Temporary cardiac pacemaker was performed and she was treated with activated charcoal, glucagon, amrinone, and several sympathomimetics, and 48 hours after admission, she was fully recovered.

BACKGROUND: As the population of immunocompromised patients continues to grow, the incidence of infections caused by opportunistic filamentous fungi will continue to increase. Inhalation of fungal spores which are found in the environmental air precedes infection with molds. We investigated the relative frequency of various molds recovered from hospital air as compared to isolates from clinical specimens. METHODS: Air samples were taken from 83 sites in Chonnam University Hospital during December 1997. Air sampler (Biotest, Germany) with Rose Bengal agar strip (Biotest, Germany) was calibrated to take 40 liters of air. The strips were incubated at 37degrees C for 2-14 days. The results of air cultures were compared with those from the clinical specimens during a year (1997). RESULTS: Of 83 air samples cultured, 61 (73.5%) were positive for molds: 43 (51.8%) samples with 1-2 CFU, 15 (18.1 %) samples with 3-5 CFU, and 3 (3.6%) samples with > 5 CFU. A total of 184 molds were isolated and the most frequently recovered molds were Cladosporium (26.0%), followed by Penicillium (25.5%), Aspergillus (18.5%) and Alternaria (9.8%). The most frequently isolated molds from clinical specimens were Aspergillus (62.8%) and Fusarium (20.2%). For Aspergillus species, A. flavus (28,8%) and A. fumigates (25.4%) were predominant among the clinical isolates, whereas A sydowii (44.1%) and A. niger (38.2%) were common in the hospital air. CONCLUSION: This result shows that Cladosporium and Penicillium are the predominant molds in the hospital air and the relative frequency of molds recovered from hospital air is quite different from those of clinical isolates.

BACKGROUND: Surgery has been considered the most effective and standard treatment modality in non-small cell lung cancer(NSCLC). However in stage IIIA lung cancer, the role of surgery is still controversial. To evaluate the role of surgery for stage IIIA NSCLC, we investigated the survival after surgery and the prognostic factors. MATERIAL AND METHOD: We evaluated 158 consecutive cases of stage IIIA NSCLC patients operated on between 1990 and 1996. There were 130 male patients and 28 female patients, and the mean age was 58.5 years. All patients except one underwent lung resection beyond lobectomy and extended mediastinal dissection. Postoperative adjuvant therapy were undertaken in 145(94.8%) patients. All patients(153) were followed and the mean follow-up period was 21.4months. RESULT: Twenty nine cases of the postoperative complications developed in 25 patients (15.8%). There were 5 operative mortality cases(3.2%) and the main cause of death was acute respiratory distress syndrome (ARDS). Local or distant recurrences developed in 84 patients(54.9%). The 5-year survival of 153 patients was 29.6% and the median survival time was 18.0 months. The 5-year survival of non N2 disease group(36.8%) was better than that of N2 disease group(26.6%)(p=0.35) and the 5-year survival of squamous cell carcinoma (38.1%) was better than that of adenocarcinoma(25.7%)(p=0.39) however there were no significant differences. Regarding the postoperative adjuvant therapy, in combined therapy group(84 patients), radiotherapy group(37 patients) and chemotherapy group(24 patients), the 5-year survival were 31.3%, 32.4%, and 14.6% respectively. There was no difference of survival between radiotherapy and combined therapy group(p=0.31), however the survival of the combined therapy group was better than the chemotherapy group(p=0.005). The survival of the complete resection group(31.9%) was better than the incomplete resection group(16.6%) however there was no significant difference(p=0.19). CONCLUSION: These observations indicate that the good 5-year survival(29.6%) in patients with stage IIIA NSCLC result from the agressive surgical treatment including extensive mediastinal nodes dissection.

Despite advances in surgery, radiotherapy, and chemotherapy, the survival of patients with oral squamous cell carcinoma has not significantly improved over the past several decades. Gene therapy is currently under investigation and shows us new possibility of cancer curing method. This experiment was undergone to find out the cell growth inhibition effect and evidence of apoptosis by HCCS-1(human cervical cancer suppressor-1), one of the candidates of tumor suppressor gene, transducted to human oral cancer cell line. To determine the efficiency of the adenovirus as a gene delivery vector cell line was transducted with LacZ gene and analysed with X-gal staining. Northern blot was performed to confirm the transfection with HSCC-1 gene and cell viability was assessed by cell cytotoxicity assay using cell count kit(CCK). To show the evidence of apoptosis, DNA fragmentation assay and flow cytometry(FACS) were performed. We had successfully construct the recombinant HSCC-1 adenovirus(Ad5CMV-HCCS-1), and importation efficiency was 20% at 2 MOI(multiplicity of infection), 80% at 20 MOI. Northern blot analysis showed that a single 0.6kb mRNA transcript was expressed in Ad5CMV-HCCS-1 transducted cell lines. As a result of CCK, when comparing to control subjects, transducted group showed 50% growth inhibition. In DNA fragmentation assay, according to increasing of MOI, DNA volume was diminished. In FACS analysis, DNA distribution showed fragmentation.This results imply that HCCS-1gene has growth inhibition effect in human oral cancer cell lines through apoptosis induction.

OBJECTIVE: To determine whether the somatostain analogue, octreotide, pretreatment before ovulation induction with human menopausal gonadotropin (hMG) affects ovarian response, and ovulation induction outcome in infertile patients with polycystic ovarian syndrome (PCOS) resistant to clomiphene citrate (CC) METHODS: From November 1998 to June 1999, 30 infertile patients with PCOS unresponsive to CC were randomly allocated either octreotide pretreatment (treatment group) (n = 15) or hMG alone (control group) (n = 15) groups. In the treatment group, 100 g of octreotide were administered daily for 7 days after progesterone injection for withdrawal bleeding, and then hMG was administered for ovulation induction. RESULTS: There were no differences in the total number of hMG ampules required and the duration of hMG administration between the two groups. The number of follicles of 10-14 mm diameter on the day of hCG injection was significantly less in the treatment group than that in the control group (4.3 +/- 2.5 vs. 9.6 +/- 4.4, p < 0.001). The serum estradiol (E2) level on the day of hCG injection was significantly lower in the treatment group, with 1579.2 +/- 421.0 pg/ml compared with 2120.3 +/- 512.7 pg/ml in the control group (p < 0.001). The hematocrit level on the day of hCG injection was also significantly lower in the treatment group than that in the control group (36.9 +/- 2.1% vs. 40.8 +/- 2.9%, p < 0.05). The incidence of severe ovarian hyperstimulation syndrome (OHSS) seemed to be lower in the treatment group, but the difference did not achieve significance (6.7% vs 20.0%). CONCLUSION: This study suggests that octreotide pretreatment before ovulation induction could improve hormonal milieu compared to hMG alone, and therefore may be effective in ovulation induction for patients with PCOS resistant to CC.

STUDY DESIGN: A case report. OBJECTIVES: To report a rare case of a surgically treated tuberculous myelitis and arachnoiditis patient with incomplete paraplegia. SUMMARY OF LITERATURE REVIEW: Tuberculous myelitis and arachnoiditis is a rare disease with a high rate of neurologic deficit. This condition is treated using antituberculous medication and high-dose steroid therapy, but surgical treatment has rarely been reported and the outcomes vary. MATERIAL AND METHODS: A 29-year-old female had tuberculous myelitis and arachnoiditis. The patient was treated with antituberculous medication and high-dose steroid therapy, but the treatment failed and the patient could not walk because of incomplete paraplegia. The surgical treatment was performed twice; we decompressed by total laminectomy and debrided the infected arachnoid membrane. Four months after surgery, we performed anterior interbody fusion due to the development of spondylitis with kyphosis. RESULTS: Three years after the first operation, the patient's neurologic state improved and she could walk 90 m without assistance. CONCLUSIONS: Here, we report a very rare case of surgically treated tuberculous myelitis and arachnoiditis and provide a treatment option for this condition to spine surgeons.
