OBJECTIVE: Uterine cervical cancer is the most common malignant tumor in Korean women. Human papillomaviruses are associated in 85-90% of the cases. However, other cofactors are considered to be important in carcinogenesis. There is an evidence that the uterine cervix is the site of shedding of the Epstein-Barr viruses(EBV). Furthermore the virus has been detected in cervical intraepithelial neoplasia and invasive carcinoma of the uterine cervix. We studied to evaluate the role of EBV in cervical carcinogenesis. METHODS: Non-neoplastic cervices(12), carcinoma in situ(32), microinvasive squamous cell carcinomas(9), invasive squamous cell carcinomas(37) and adenocarcinomas and adenosquamous carcinomas(14) were studied for EBV infection. PCR and in situ PCR for EBNA-1 were done and subtyping was done using PCR for EBNA 3C. RESULTS: In non-neoplastic cervix, EBV was detected in 16.7% by PCR and found in normal epithelial cells and lymphocytes in in situ PCR. By PCR technique, EBV was detected in 65.6% of CIS, 66.3% and 51.4% of microinvasive and invasive squamous cell carcinomas, 57.1% of adenocarcinomas and adenosquamous carcinomas. EBV subtyping was done in EBV positive cases by PCR and all showed type 1. CONCLUSION: EBV was detected in higher frequency in cervical cancer than in non-neoplastic cervix. However the frequency was not correlated to the invasion depth and histologic types of cervical carcinomas. EBV was detected in tumor cells as well as normal epithelial cells and lymphocytes also. It was suggested that EBV may play a role in cervical cancers but the mechanism in carcinogenesis remains to be solved.

Surface ECG findings in 29 patients with left isomerism were reviewed. Among the total 46 wave axis distributions, 25(54%) were abnormal axis, not originated from sinus node. Congenital atrioventricular block was found in 2 children. 6 patients showed the bradycardia and junctional escape rhythm intermittently or persistently. 4 of them, not related with heart surgery, were much older than 2 patients who showed these ECG findings after heart surgery. These ECG findings suggested the possibility of occurrence of sinus node or subsidiary pacemaker dysfunction in the patients with left isomerism, especially in the older patients. So we thought that electrophysiologic evaluation is necessary in some patients with left isomerism.

Intracavernous self-injection therapy is now being widely used to treat patients with erectile dysfunction. Many men with erectile dysfunction can achieve normal erection with this therapy, but about 50% of men using this therapy eventually discontinue treatment for reasons relating to penile pain, needle-phobia and side effects including corporeal scarring, penile hematoma and priapism. Therefore, the less invasive route of drug administration is highly recommended. We investigated the efficacy and safety of transurethral instillation of PGE1 solution for the treatment of erectile dysfunction in comparison with an intracavernous injection of PGE1. Forty seven normal males and nine neurogenic impotent patients due to spinal cord injury (SCI) were enrolled in this study and all subjects were evaluated with the penile duplex color doppler ultrasonography before and after the drug administration. Penile length and circumference were measured before and after the drug administration. The erectile response was recorded on a five-point erection assessment scale by Padma-Nathan. Of 12 normal males used transurethral instillation of PGE1 solution 5 (42%) were achieved erection allowing sexual intercourse (score 4 or 5). The mean peak systolic velocity at 30 minutes was 75.82+/-56.84cm/sec, 63.11 +/- 48.11cm/sec and end diastolic velocity at 30 minutes was 3.49+/-8.10cm/sec, 10.51 +/- 1.12cm/sec and resistance index was 0.96+/-0.15, 0.78+/-0.15 in normal males and SCI patients respectively. Mean length and circumference of penile shaft before and after transurethral instillation of PGE1 showed significant difference. Of 9 patients, 5 (55.5%) were achieved erection allowing sexual intercourse. With the transurethral instillation of PGE1 solution, urethral pain and burning sense were noticeable complication but systemic side effect was not noticed. In conclusion, transurethral PGE1 instillation can be satisfactorily used for the patients with erectile dysfunction of less prominent organic and neurogenic origin, although the effect of transurethral instillation of PGE1 is obviously less than that of intracavernosal injection.

Rigid posterior fixation of the atlas to the third and fourth cervical spine was achieved in a patient in whom axis pedicle fracture and dislocation of axis on the third cervical spine. Althouth there was no evidence of neurologic disorder, marked instability of axis on the third cervical spine should inevitably be fused in any procedures. An anatomically contoured loop was secured to the posterior arch of the atlas and the laminae of the third and the fourth cervical spine by sublaminar wirings. The technique has the advantage over bone graft, either alone or with cement, in that it affords rigid stabilization, allows early mobilization and some flexion movement of atlanto-occipital joint.

Objectives:
. Common cavity deformity is a rare congenital bony labyrinth malformation associated with profound hearing loss. Cochlear implants are widely used for hearing rehabilitation for common cavity deformities; however, the reported prognosis is poor. Due to the deformed anatomical structure, it is important to consider the position of the electrodes to maximize the performance of the cochlear implant. The present study discusses the impact of electrode placement on hearing outcomes.
Methods:
. A retrospective medical chart review of eight common cavity deformity patients (10 cochlear implants) who received cochlear implants was performed at a single university hospital. In all eight patients, implant surgery was performed using single-slit labyrinthotomy. Electrodes wer e manually bent before insertion to prevent misplacement and to reduce physical damage to the neuroepithelium.
Results:
. Four of the 10 electrodes were misplaced, with their tips placed in the anterior semicircular canal or internal auditory canal. However, after implant surgery, all patients—including those with misplaced electrodes—gained auditory perception and improved hearing function. One patient who had electrodes that did not contact the inner wall of the cavity showed limited activity of the electrodes (27%) compared to others (64%–100%).
Conclusion
. Proper contact of the electrode with the inner wall was more likely to be important for cochlear implant success in cases of common cavity deformity than appropriate placement of the electrode tip.

The incidence of uterine prolapse during pregnancy is rare. A 34-year-old G3P1 was initially presented at 16 weeks 5days of gestation with a prolapse of the uterine cervix. The cervix was edematous and protruding beyond introitus. Management included bed rest, and the patient was discharged after several days with a vaginal pessary to help maintain cervical placement. At 35 weeks of gestation, the patient did not experience any further prolapse after the removal of the pessary. Pregnancy progressed to term with no further prolapse. She was readmitted at 38weeks 5days of gestation with spontaneous labor. She delivered a 3.36kg male with an Apgar score at 1 minute and at 5 minutes of 7 and 8 respectively. The patient's cervix remained prolapsed in the early postpartum period; however it was easily reduced prior to discharge. After puerperium, the patient's cervix remained prolapsed. She was fitted with a vaginal pessary for uterine support. We reported this case with related literature.

We report a case of atypical eruption due to chemotherapeutic agent in a 60-year-old man who presented with asymptomatic, erythematous, 0.5cm in diameter, confluent, and elevated papules and plaques confined to the face. The patient was previously diagnosed with small cell carcinoma of the lung with liver metastasis. Two months after the diagnosis, a first course of chemotherapy including etoposide was started. Five days after starting the chemotherapy, the patient developed a facial eruption. Histopathologic examination demonstrated increased epidermal mitotic figures, cells in metaphase arrest, basal cell layer hyperpigmentation, prominent dyskeratosis, and squamous atypia. The most distinctive histologic feature was the presence of starburst cells, which are markedly enlarged pale staining keratinocytes containing small basophilic fragments of nuclear debris haphazardly scattered throughout the cytoplasm in a starburst pattern.

PURPOSE: This study evaluated the treatment effectiveness and proper radiation dose of helical tomotherapy (HT) in spine oligometastases from gastrointestinal cancers. MATERIALS AND METHODS: From 2006 to 2010, 20 gastrointestinal cancer patients were treated with HT for spine oligometastases (31 spine lesions). The gross tumor volume (GTV) was the tumor evident from magnetic resonance imaging images fused with simulation computed tomography images. Clinical target volume (CTV) encompassed involved vertebral bodies or dorsal elements. We assumed that the planning target volume was equal to the CTV. We assessed local control rate after HT for 31 spine metastases. Pain response was scored by using a numeric pain intensity scale (NPIS, from 0 to 10). RESULTS: Spine metastatic lesions were treated with median dose of 40 Gy (range, 24 to 51 Gy) and median 5 Gy per fraction (range, 2.5 to 8 Gy) to GTV with median 8 fractions (range, 3 to 20 fraction). Median biologically equivalent dose (BED, alpha/beta = 10 Gy) was 52 Gy10 (range, 37.5 to 76.8 Gy10) to GTV. Six month local control rate for spine metastasis was 90.3%. Overall infield failure rate was 15% and outfield failure rate was 75%. Most patients showed pain relief after HT (93.8%). Median local recurrence free survival was 3 months. BED over 57 Gy10 and oligometastases were identified as prognostic factors associated with improved local progression free survival (p = 0.012, p = 0.041). CONCLUSION: HT was capable of delivering higher BED to metastatic lesions in close proximity of the spinal cord. Spine metastases from gastrointestinal tumors were sensitive to high dose radiation, and BED (alpha/beta = 10 Gy) higher than 57 Gy10 could improve local control.

Palliative endourologic treatment was done in 94 cases for ureteral obstruction secondary to advanced malignancy The average survival was 4.2 months. The obstruction were caused by metastases or invasion of cancer in all patients. First we tried to insert a double J stent(STENT), when it failed percutaneous nephrostomy(PCN) was performed. Initially 16 patients were treated by STENT and 8 patients by PCN. The SIENT was changed 2.2 times on the average in all patients. 75% of the patients who had been treated by STENT experienced only one or two times of STENT changes before dying. Patency period of the STENT was 57.6 days on the average. The patency period was shorter in the patients who showed gross hematuria at the time of STENT insertion. Although survival was not so long, 60.6% patients were able to return to their homes. The endourologic management of the upper urinary tract obstruction will play a more important role and offer a better quality of life for end stage cancer patients.
