PURPOSE: The limited information regarding preservation of erectile function following castration is based on self-reports by castrated patients. Therefore, we evaluated the erectile status in 38 patients with advanced prostatic cancer. MATERIALS AND METHODS: Castrations were achieved by bilateral orchiectomy, estrogen therapy of both. Patients answered the questionnaires regarding the medical status and erectile function before and after castration, and the blood levels of testosterone were assessed. Especially in seven patients, penile circumference and erection quality were monitored during the visual sexual stimulation. RESULTS: 11 patients(58%) out of 19 potent men achieved functional erection after castration. Mean serum testosterone level was 0.31 +/-0.19ng/ml in men who were potent after castration and 0.06+/- 0.04ng/m1 in those not potent(p<0.05). No statistically significant differences were noted in age, interval after castration, method of castration, degree of gynecomastia, stage of prostatic cancer and doing radiation therapy between the men who did and did not achieve erection(p>0.05). CONCLUSIONS: Following castration, sexual potency and libido decreased markedly in most cases, but 58% retained some degree of normal sexual potency. And, statistically significant difference was noted only in serum testosterone level between the men who did and did not achieve erection.

OBJECTIVE: The objective of this study were to clarify the significance of PCNA and DNA ploidy as a possible parameter of the prognosis in squamous cell carcinoma of the uterine cervix. STUDY DESIGN: Women with the diagnosis of cervical cancer operated between January 1987, and July 1991, composed the study group(n=35) in this case-control group. Among these 35 patients.In theese patients we chose the patients with complete follow up treatment. Also we employed 7 control paraffin-embedded cervical specimens without any specific pathologic lesions for the comparison. Immunohistochemical staining to identify PCNA was applied to case of paraffin section and PCNA indices was obtained. DNA analysis was done by using flow cytometry and S-phase fraction and DNA ploidy were obtained. RESULT: The results were summarized as follows. 1. S-phase fraction were 20+/-7% in cervical cancer and 16+/-11% in control group. There were no statistical difference. Aneuploid ratio were 26%(9/35) in cervical cancer and 0%(0/7) in control group. There were statistical difference. PCNA indices were 45+/-6% in cervical cancer and 5+/-4% in control group. There were statistical difference. 2. There were no statistical difference in PCNA indices between large cell keratinizing type, and large cell nonkratinizing type of cervical cancer. 3. According to lymph node metastasis, there were no statistical difference in PCNA indices between positive group and negative group.4. According with various pathologic parameters, recurrence rate was hihger in cases of parametrial involvement. 5. The correlation of coefficient was 0.747 between PCNA indices and S-phasd fraction that is a significant relationship.6. According to recurrence, there were no statistical difference in S-phase fraction, aneuploidy and PCNA indices between group of recurrence and no recurrence.7. There were no statistical difference between <20% group nad>20%, group of S-phase, aneuploid and <60%, group and >60%, group of PCNA index in view of recurrence rate. conclusion: That is a significant relationship between S-phase fraction and PCNA indices, But, there are no statictical significance of PCNA indices, DNA ploid and a prognostic factor. So, that is a limitation in PCNA index DNA ploid when it was used as as prognostic parameter of nterine cervical cancer.

BACKGROUND AND OBJECTIVES: Electrical dyssynchronicity (Dsyn) appears to be prognostic of survival in congestive heart failure (CHF). Recent study has shown some discrepancy between the electrical Dsyn and the Doppler tissue image (DTI) assessed mechanical Dsyn. The aim of our study was to evaluate the relationship between the QRS duration and DTI assessed Dsyn. SUBJCETS AND METHODS: One hundred and forty patients, with CHF and left ventricular ejection fractions < or =40%, were enrolled. DTI was performed on 5-basal and 5-mid segments to assess the time from the R-wave to the peak systolic velocity (RS time). A QRS duration >130 msec, standard deviation (SD) of the RS time >40 msec, or a difference in the maximal and minimal RS times (RS time-diff) >100 msec were indicators of'Dsyn'. RESULTS: The prevalence of myocardial Dsyn, by QRS duration, SD of the RS time and the RS time-diff were 19, 43 and 47%, respectively. The SD of the RS time (49.8+/-23.6 vs. 36.6+/-20.7, p<0.01) and the RS time-diff (139.2+/-63.2 vs. 98.0+/-54.3, p<0.01) were prolonged in the wide (>130 msec) compared with the narrow QRS group. There was also a weak positive correlation between the QRS duration and the SD of the RS time (R=0.34, p<0.001) and the RS time-diff (R=0.38, p<0.001). However, from a cross-tabulation analysis, more than one third of patients had a discrepancy between QRS duration and DTI assessed mechanical Dsyn. From a multivariate analysis, a major determinant of the SD of the RS time was the QRS duration. CONCLUSION: Although a major determinant of the DTI assessed Dsyn was the QRS duration, more than one-third of patients had a discrepancy between electrical and mechanical Dsyn. Therefore, not only the QRS duration, but the DTI assessed Dsyn, should be measured when considering cardiac resynchronization therapy.

OBJECTIVE: Impaired local cellular immunity contributes to persistent human papillomavirus (HPV) infection and development of cervical intraepithelial neoplasia (CIN). Programmed death-1 (PD-1) and its ligands PD-ligand-1 (L1) and PD-L2 are negative regulators of T cell activity in various cancers, but few studies exist. The aim of this study was to determine the clinicopathologic and immunologic parameters (PD-1, PD-L1, and PD-L2) related to the persistence/recurrence of CIN after conization. METHODS: Medical records of 652 patients diagnosed with CIN and underwent conization were reviewed. The associations between clinicopathologic parameters (e.g., age, parity, initial HPV load, etc.) and persistence/recurrence of CIN were analyzed. Expression of PD-1, PD-L1, and PD-L2 was assessed on 100 conization specimens by immunohistochemistry (IHC) in women matched for propensity-score (50 with persistence/recurrence and 50 without). RESULTS: Initial HPV load (>1,000 relative light unit) and positive margin were shown to be significantly associated with CIN persistence/recurrence (p=0.012 and p < 0.001, respectively). Multivariate analysis showed that margin status was an independent predictor of persistence/recurrence (hazard ratio=8.86; 95% confidence interval=1.67–16.81; p < 0.001). On IHC analysis, none of the patients expressed PD-L1. PD-1+ T cells were observed in 25 of 100 patients. Also, PD-1+ T cells were significantly correlated with increasing grade of CIN (p=0.031). In addition, patients with persistence/recurrence had increased expression of PD-1 compared with those without (36% vs. 14%, respectively; p=0.020). Although PD-L2 expression did not differ between 2 groups, it was significantly higher in patients with high-grade CIN compared to low-grade (34.7% vs. 12%, respectively; p=0.041). CONCLUSION: Positive surgical margin and expression of PD-1+ T cells were associated with CIN persistence/recurrence after conization.

The authors attempted to analyse the factors influencing the mortality involved in aneurysm surgery based on 38 cases of intracranial surgery for anterior communicating aneurysms, and obtained the following conclusion. 1. The surgical results are much better when the aneurysm surgery is delayed over one week after the occurrence of aneurysmal rupture, if there is no evidence of intracerebral hematoma. Administration of a massive dosage of epsilon aminocaproic acid in the waiting period prior to aneurysm surgery seems to be effective for preventing recurrence of bleeding from the aneurysm. 2. The direction of the anterior communicating aneurysm should be clearly visualized on a cerebral angiogram so that the most effective aneurysmal approach can be selected in surgery. 3. Microsurgery and hypotension in aneurysm surgery minimize brain damage in the exposure of aneurysm and provide accurate isolation of the aneurismal neck from the parent vessel in aneurysmal neck ligation. 4. Proximal ligation of the anterior cerebral artery is also an effective procedure to prevent recurrent hemorrhage from anterior communicating aneurysm.

BACKGROUND: Left ventricular dysfuction is common in immediate postoperative periods after surgical correction of heart diseases with chronic left ventricular volume overload. We speculated postoperative changes of left ventricular volume and unction in patients with patent ductus osus(PDA) who had underwent surgical repair at ages older than 16 years. Factors influencing postoperative left ventricular volume and function were also analyzed. MATERIAL AND METHOD: From August 1989 to August 1999 thirty-siz adult patients with PDA 28 females and 8 males. were enrolled in this study. Their age ranged from 16 years to 57 years(mean :32 years). Types of surgical repair were division with primary closure in 22, division with patch closure in 6, internal obliteration using cardiopulmonary bypass in 4 and ligation in 4. Aortic clamping was combined during surgical repair in 22(61%) and cardiopulmonary bypass was used in 8(22%) Two-dimensional echocardiography studies were performed in 34(94%) preoperatively and in 25(66%) immediate postoperatively to assess postoperative changes of left ventricular internal dimensions. left ventricular volume and ejection fraction. Duration of postoperative follow-up ranged from 1 month to 99 months (mean:22 months) and 10 patients underwent 16 echocardiographic evaluation during this period. RESULT: Preoperative and postoperative left ventricular systolic dimensions(LVIDs) were 42+/-8.0mm and 42+/-8.3mm left ventricular diastolic dimensions(LVIDd) were 64+/-10.0mm and 56+/-7.4mm left ventricular end systolic volumes(LVESV) were 62+/-19cc (z=1.87+/-0.06) and 59+/-24cc(z=1.78+/-0.08) left ventricular end diastolic volumes(LVEDL) were 169+/-40cc(z-1.17+/-0.1) and 112+/-29cc(z=0.85+/-0.1) and ejection fractions(EF) were 66+/-6.7% and 48+/-12.6% respectively. There were statistically significant differences between preoperative and postoperative values in LVDIDd(p=0.001) LVEDV(p=0.001) and EF(p=0.0001) while no significant difference is LVIDs and LVESV. Postoperative depression of ejcection fraction was significantly related with z-score of preoperative LVESV and LVEDV by univariateanalysis while LVEDV only was significant risk factor for postoperative LV dysfunction by multiple regressioin analysis (deltaLVEF=-13.3-4.62xLVEDV(z), p=0.001) During the follow-up periods ejection fractions become normalized in all except one patients. CONCLUSION: Left ventricular function is usually deteriorated after the surgical correction of PDA in adult age and preoperative LVEDV is a major determinant of postoperative LV function.

Infections of the oral and maxillofacial region are one of the most common conditions for which a patient presents to a maxillofacial surgeons. Although these infections can arise from a variety of source, dental disease is the most common etiology. So, odontogenic infection are frequently encountered in the practice of oral and maxillofacial surgery. These infections often respond to antimicrobial chemotherapy or surgical intervention, such as extraction of teeth, incision and drainage through clinical features. But, odontogenic infections have the potential to spread via the fascial spaces in the head and neck region, and, they spread to cavernous sinus, deep musculofascial space and other vital structure. We have undertaken clinical studies on infections in the oral and maxillofacial regions by analyzing retrospectively hospitalized patients in the Department of Oral and Maxillofacial Surgery, Chonbuk National University Hospital past 5 years from 2000 to 2004. And, the patients'age, sex, medical history, causes of the infection, surgical intervention, and other clinical parameters were reviewed. The obtained results were as follows: 1. The most frequent cause of oral and maxillofacial infection was odontogenic. And in the odontogenic cause, dental caries was the most common cause (47.2%). 2. The most common fascial space involved was the submandibular space (15.7%), followed by the buccal space (14.8%). 3. 60.4% of all patients required surgical drainage of the abscess, endodontic treatment or tooth extraction or periodontal treatment with drainage. 4. The most causative organism isolated from the pus culture were streptococcus viridans (53.9%). 5. Underlying medical problems were found in 136 patients (41.9%), the most common being hypertension (27.9%) and diabetes (14.7%).

OBJECTIVES: Genome-wide association studies (GWASs) and meta-analyses indicate that single-nucleotide polymorphisms (SNPs) in the a-1C subunit of the L-type voltage-dependent calcium channel (CACNA1C) gene increase the risk for schizophrenia and bipolar disorders (BDs). We investigated the association between the genetic variants on CACNA1C and schizophrenia and/or BDs in the Korean population. METHODS: A total of 582 patients with schizophrenia, 336 patients with BDs consisting of 179 bipolar I disorder (BD-I) and 157 bipolar II disorder (BD-II), and 502 healthy controls were recruited. Based on previous results from other populations, three SNPs (rs10848635, rs1006737, and rs4765905) were selected and genotype-wise association was evaluated using logistic regression analysis under additive, dominant and recessive genetic models. RESULTS: rs10848635 showed a significant association with schizophrenia (p=0.010), the combined schizophrenia and BD group (p=0.018), and the combined schizophrenia and BD-I group (p=0.011). The best fit model was dominant model for all of these phenotypes. The association remained significant after correction for multiple testing in schizophrenia and the combined schizophrenia and BD-I group. CONCLUSION: We identified a possible role of CACNA1C in the common susceptibility of schizophrenia and BD-I. However no association trend was observed for BD-II. Further efforts are needed to identify a specific phenotype associated with this gene crossing the current diagnostic categories.

Purpose:
We sought to evaluate the safety and effectiveness of patient-specific ocular prostheses produced by three-dimensional (3D) printing and the sublimation technique. A comparison with prostheses produced using manual manufacturing methods was then performed.
Methods:
To confirm the biological and physiochemical safety, cytotoxicity, systemic acute toxicity, intradermal reaction, and skin sensitization tests were conducted according to the International Organization for Standardization guidelines. The compressive strength of the prostheses was also tested. Further, a case series of three patients who wore the 3D printed prostheses for more than eight hours daily for 4 weeks was executed. Self-assessments by these individuals using a questionnaire and safety evaluations focusing on the occurrence of conjunctival inflammation or allergic reactions according to the Cornea and Contact Lens Research Unit criteria by slit-lamp examination and similarity assessment were completed.
Results:
The 3D printed ocular prostheses met the necessary qualifications per the biological and physiochemical safety tests, showing the absence of cytotoxicity, acute systemic toxicity, intradermal reactivity, and skin-sensitizing potency. Also, there was no difference in strength test results between previous ocular prostheses and the 3D printed ones. Self-assessment by the patients yielded satisfactory results, with no significant difference in the level of satisfaction reported for the 3D printed and previous handmade ocular prostheses. The 3D printed prosthesis did not trigger any side effects in the conjunctival sac and showed similar objective findings with respect to the color of the iris, sclera, and vessel patterns.
Conclusions
Our study confirms the biologic and physiochemical safety of 3D-printed ocular prostheses created using computer-aided design technology and a sublimation technique. The patients’ questionnaires and the judgment of the ophthalmologists/ocularists showed that the 3D printed ocular prosthesis was acceptable in function and appearance through a case series report.
