The gross tissue specimens are a valuable aid to the teaching of pathology and anatomy. However, traditional methods for storage and handling of them are discouragingly difficult and, recently, minimal surgical resections as well as preoperative interventions make it more difficult to have instructive gross specimens. Plastination is a process of tissue preservation by impregnation with silicone polymers or epoxy resins. The process in our study involves dehydration by cryosubstitution in aceton, defatting, forced impregnation of silicon polymer in a vacuum, curing and finishing. We submitted 40 surgically resected specimens to plastination. The resulting specimens are odorless, relatively dry, durable, life-like, non-hazardous, maintenance-free, and do not deteriorate with time. Plastinated specimens are a useful adjunct to the teaching of pathology, particularly suited for use in small groups, and appropriate method of tissue preservation. They are much preferred to wet preparation and conventional pots by both students and teachers owing to their accessibility, superior illustrative powers, and comparative ease of interpretation.

PURPOSE: The tension free vaginal tape (TVT) procedure was reported as a new treatment option for stress urinary incontinence (SUI) in female. We report our early result of TVT procedure for the surgical treatment of SUI. MATERIALS AND METHODS: Of 110 consecutive women with SUI who underwent the TVT procedure between March 1999 and May 2000, 89 patients followed up more than six months were included in this study. The procedure was carried out in accordance with the established method under local anesthesia with sedation. RESULTS: Mean age was 55.1 years (37-79). Mean follow-up was 11.2 months (6.1-20.3). Mean hospital stay was 1.1 day (0-8) and mean operation time was 34.6 minutes (15-70). Mean duration of post operative indwelling catheter was 8.1 hours (0-24). Subjectively, 76 (88.8%) of the patients were cured and 7 (7.8%) significantly improved. The cure rate among patients with a maximal urethral closure pressure (MUCP) lower than 40cmH2O was 75.7%, while that of patients with a MUCP higher than 40cmH2O was 98.1% (p<0.001). Complications were immediate postoperative urinary retention in 14 patients (15.7%), bladder perforation in 6 (6.7%) and wound infection in 1 (1.1%). In 4 patients (4.4%), de novo urgency incontinence was documented. CONCLUSIONS: The TVT procedure is safe, simple and effective for the treatment of SUI in terms of short hospital stay, short operation time, high sucess rate and low complication rate. But it might be prudentially applied to the patients with very low urethral closure pressure.

The routine screening of patients for hypercalcemia has increased the incidence of hyperpa-rathyroidism, But, Primary hyperparathyroidism is relatively rare disease in korea. Especially, primary hyperparathyroidism caused by parathyroid chief cell hyperplasia has not been reported. The numbers of patients with bone disease, renal stones, other severe complication has declined, but the numbers of patients with psychiatric and neuromuscular disturbance or with asymptomatic disease has increased. We experienced a case with severe bone diseases due to primary hyperparathyroidism caused by parathyroid chief cell hyprepiasia which was confirmed through the mearsurement of serum calcium and parathyroid hormone, neck CT scanning and surgical exploration and which was managed by total parathyroidectomy with autotransplantation.

Successful thoracic endovascular repair for complicated Stanford type B acute aortic dissection in two patients is herein reported. The true lumen flow was immediately restored following stent graft deployment in the descending thoracic aorta with subsequent resolution of the distal malperfusion syndrome. One patient is doing well more than 15 months after surgery and another patient who was treated more recently is also doing well 7 months postoperatively.

Acute eosinophilic pneumonia is reported as a specific disease entity. But, it is different from chronic eosinophilic pneumonia in its onset, clinical course and recurrence. Badesh et al reported the following diagnostic criteria os acute eosinophilic pneumonia a less than one-month history of symptoms prior to diagnosis, no evidence of asthma, the absence of other organic disease, no obvious etiology and an evidence of recurrent disease. We experienced a case of acute eosinophilic pneumonia in 37 old male. Pathologically eosinophilic pneumonia is confirmed and other features meet Badesh's criteria.

Warfarin is widely used for the prevention of cerebral infarction, especially in patients with atrial fibrillation or artificial valve. Although hemorrhagic problems are well known, skin necrosis is a rare complication. Failures of early diagnosis or management may lead to serious results. We report a case of skin necrosis induced by warfarin therapy.

Postoperative coronary arterial spasm is a rare but potentially fatal complication. A 51-year-old male patient with a history of a reactive ergonovine stress test coronary angiogram developed refractory coronary artery spasm after undergoing minimally invasive direct coronary artery bypass grafting of the left anterior descending coronary artery. The patient was successfully managed with rapid implementation of intra-aortic balloon-pump counter pulsation and extracorporeal membrane oxygenation.

PURPOSE: To evaluate the effect of age on the efficacy and safety of holmium laser enucleation of the prostate (HoLEP) for the treatment of symptomatic benign prostatic hyperplasia (BPH). METHODS: A total of 579 patients underwent HoLEP procedure performed by a single surgeon (SJO) between December 2009 and May 2013. The perioperative and functional outcomes of patients in the age groups of 50-59 (group A, n=44), 60-69 (group B, n=253), 70-79 (group C, n=244), and ≥80 years (group D, n=38) were compared. The Clavien-Dindo system was used to evaluate clinical outcomes. The International Prostate Symptom Score (IPSS), maximum urinary flow rate (Qmax), postvoid residual (PVR) urine volume, and urinary continence were used to assess functional outcomes. RESULTS: In this study, the patients ≥80 years had significantly higher presence of hypertension (P=0.007), total prostate volumes (P=0.024), transitional zone volume (P=0.002), American Society of Anesthesiologists scores (P=0.006), urinary retention (P=0.032), and anticoagulation use (P=0.008) at preoperative period. Moreover, the mean values of operation time, enucleation time, morcellation time, and enucleation weight were higher in group D compared with other group patients (P=0.002, P=0.010, P<0.01, and P=0.009, respectively). Patients aged ≥80 years had a longer hospital stay time (2.9±1.8 days) than other groups (group A, 2.3±0.7 days; group B, 2.3±0.7 days vs. group C, 2.4±0.7 days; P=0.001). All groups were similar in regard to the incidence of complications (Clavien-Dindo grade) post operatively (P>0.05). All the patients in the present study showed improvement in functional outcomes after HoLEP. By the sixth month, there were no significant differences in IPSS, quality of life, Qmax, and PVR among the groups (P>0.05). CONCLUSIONS: Compared with younger patients, the patients aged ≥80 years had a similar overall morbidity and 6-month functional outcomes of HoLEP. HoLEP is a safe and effective treatment for BPH among the elderly.

E6 and E7 proteins produced by oncogenic HPV bind to the protein products of cellular tumor suppressor genes p53 and Rb, respectively. This mechanism has been suggested to contribute to the oncogenesis of HPV-infected carcinoma. The cells which are blocked the function of p53 and pub protein continue to divide by bypassing Ml stage known as antiproliferative mechanism but telomeres, the genetic elements at the ends of chromosomes, continue to shorten until the telomeres are so short that further replication is prevented(M2 stage). But telomeres can be maintained if telomerase is derepressed, giving rise to a immortal cell. The present study has been investigated the presence of HPV, telomere length and telomerase activation in cervical carcinomas. HPV DNA were detected by polymerase chain reaction in 17 of 19 precancerous lesions and cervical carcinoma specimens; HPV16 was detected in 12 cases, HPV18 in one case, HPV33 in two cases, and HPV58 in two cases. Overall, the prevalence of HPV was 89.5%. To study the difference of telomere length in cervical carcinomas and each normal counterpart, DNAs were digested with Hinf III and Rsa I to liberate the terminal restriction fragments(TRF). TRFs were resolved on agarose gels and detected by hybridization to the telomeric probe. This result indicated that there were no significant difference of TRF length in samples tested except two cases. TRF length of one carcinoma specimen was found to be significantly increased as compared with normal counterpart, but the other was found to be significantly decreased. Telomerase activity was detected in 4 of dysplasia specimens(5 cases), all of carcinoma in situ(CIS), and 6 of 8 invasive carcinoma. Overall, telomerase activity was detected in 84%. The degree of telomerase activity was high in 2 of dysplasia, 3 of CIS, and 3 of invasive carcinoma. And then there was no apparent association between HPV types and levels of telomerase activity. However, telomerase activity was depressed in invasive carcinoma as compared to dysplasia and CIS. These results suggest that HPV may be a possible causative agent in cervical carcinoma. In addition, telomerase activation may be necessary for the immortalization of cells and the progression of malignancy in cervical carcinoma.
