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.

It is well known that anatomic variations affecting the ostiomeatal unit (OMU) become one of the causes of mucosal abnormalities of paranasal sinuses (PNS). Findings of coronal plane CT scans of PNS were analyzed in 95 patients with sinusitis or sinusitis-like complaints. Anatomical variations were seen in 88 cases of 60 patients. Mucosal abnormalities were seen in 27 of 47 cases with concha bullosa, 23 of 37 cases with enlarged ethmoid bulla, 8 of 33 cases with Agger nasi, 20 of 26 cases with nasoseptal deviation, 7 of 8 cases with Haller cell, 3 of 6 cases with duoble middle turbinate, 4 of 6 cases with medially bent uncinate process, 1 cases with laterally bent uncinate process, and 33 of 40 cases with mixed variations. Mucosal abnormalities in cases with antomical variations were detected in 61 cases, including maxillary sinus(51 cases), anterior ethmoid sinus (26 cases), frontal sinus (4 cases), and mixed (32 cases). Mucosal abnormalities without anatomical variations were detected in 13 cases involving maxillary sinuses (7 cases), anterior ethmoid sinuses (5 cases), and frontal sinus(1 cases). In conclusion, as coronal plane CT scan has the capability of dolineating anatomical variations and mucosal abnormalities of PNS, it is considered useful in evaluating the treatment and prognosis of chronic or recurrent sinusitis.
