Since 1991 the orthotopic ileocolic neobladder after radical cystoprostatectomy for bladder cancer has been performed at our hospital. We report our 5 year experience of ileocolic neobladder with focus on complications, urodynamic data and continence status. Between May 1991 and April 1996, a total of 49 men underwent bladder replacement with an orthotopic ileocolic neobladder following radical cystectomy for management of invasive bladder cancer. Mean age of the patient .was 53.2 years (range 34-68) Mean follow up was 42 months (range 4-63). There was one perioperative death due to sepsis who had been suffered from diabetes mellitus. Early complications were developed in 8 patients (16.7%); neobladder leak in 1 (2.1%), wound infection in 2 (4.2%), wound dehiscence in 2 (4.2%), prolonged ileus in 1 (2.1%), and pneumonia in 1 (2.1%). Neobladder-related late complications requiring rehospitalization were noted in 7 patients (14.6%); cecourethral anastomosis site stricture in 1 (2.1%) which was treated endoscopically, ureteral strictures at the reimplantation site in 5 (7 renal unites, 10.4%) which were successfully treated with balloon dilation in 4 patients and with open revision in 1 patient, and neobladder perforation in 1 (2.1%) which was managed conservatively without sequelae. Urethral recurrence was noted in 1 patient and has been managed with M-VAC chemotherapy. There was no. vesicoureteral reflux in any patient. Urodynamic study of the neobladder at 6 months showed a low pressure (mean 24.2 cm H2O), large capacity (mean 553 ml) and an adequate maximal urethral closure pressure (mean 51.3 cmH2O). The peak flow rate in all patients was good (mean 11.3m/sec). All patients were dry during daytime but mild stress urinary incontinence was noted in 5 patients (10.4%) and nighttime continence was good in 91.7% at 6 months. Our results indicate that orthotopic ileocolic neobladder provides good functional results and would be one of the ideal urinary diversion for bladder substitution after radical cystoprostatectomy and will continue to be our procedure of choice in selected male bladder cancer patients.

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.

3.Catastrophic complications from filler injection on external genitalia
Archives of Plastic Surgery 2021;48(1):10-14
Soft tissue filler injections are widely used due to their immediate effects, predictable results, and high stability. However, as the use of soft tissue filler injections has increased, various complications have been reported. We report a life-threatening complication in a patient who developed sepsis and necrotizing fasciitis. A 45-year-old woman presented with right leg pain and discharge from the labia majora. The patient had received a soft tissue filler injection of unknown composition 1 year earlier and had recently undergone incision and drainage for an inflammatory cystic nodule. Antibiotic treatment was administered for cellulitis, but the infection progressed to necrotizing fasciitis and sepsis. Fasciotomy and intensive care unit treatment improved the systemic infection, but the soft tissue filler injection site did not respond to treatment for 1 month. Thus, the injection site was covered with a pedicled vertical rectus abdominis musculocutaneous flap after wide excision. The area of skin necrosis on the leg was covered with split-thickness skin grafts. Infections occurring after soft tissue filler injections are related to biofilms, and treatment is sometimes difficult. Therefore, although soft tissue filler injections have a favorable safety profile, it is important to be aware of the risk of life-threatening complications.

Granular cell tumor is one of the rare tumorous condition. At present there are estimated 600 reported examples of the tumor in the medical literature. Malignant granular cell tumor is a well established but extremely rare entity that is found in appr- oximately 2 % of all granular cell tumor. Diagnosis should be restricted to neoplasms that are similar in their histological appearance to benign granular cell tumors but can be seperated on the basis of cellular pleomorphism, mitotic activity, and, most importantly, their capacity to produce metastases. The authors had experienced that a 55 years old male patient had two large malignant granular cell tumors at the left thigh and left inguinal area with metastatic lesion.

OBJETIVE: To assess the effects of progesterone and acetyl-L-carnitine used after treated with IsolateR gradient before semen cryopreservation-thawing on sperm parameters and membrane integrity. MATERIALS AND METHODS: From April 2001 to July 2001, ten normal male partner of couples who were visited in vitro fertilization (IVF) clinics. the semens were treated with IsolateR gradient before cryopreservation, spermatozoa was incubated with progesterone (1, 5 and 10 micrometer), acetyl-L-carnitine (2.5, 5 and 10 micrometer), or both (progesterone, 1 micrometer; and acetyl-L-carnitine, 5 micrometer) for 30 min. RESULTS: There were no differences in sperm parameters and vital stain among isolate only treated group, progesterone (1, 5 and 10 micrometer), acetyl-L-carnitine (2.5, 5 and 10 micrometer) and both (progesterone, 1 micrometer; and acetyl-L-carnitine, 5 micrometer). But, in high concentration of acetyl-L-carnitine (10 micrometer) treated group, sperm parameters and vital stain were decreased. The statistical method was used ANOVA (Kruskal-Wallis test) and p value was <0.01. CONCLUSIONS: Neither progesterone nor acetyl-L-carnitine show to be protective effect on the cryodamage assessed by sperm parameters and vital stain (eosin-Y stain) in normal sperm. High concentration of acetyl-L-carnitine (10 micrometer), however, was harmful effect on cryoprevention.

Sebaceous carcinoma (SC) is a rare tumor, accounting for approximately 0.7% of skin cancers. SC can be classified as ocular SC (OSC) or extraocular SC (EOSC) depending on its location. Because EOSC accompanied by metastases is rare, there is a paucity of data about EOSC accompanied by metastasis. This study presents a case of an aggressive EOSC of the scalp with lymph node metastases. The patient underwent wide local excision of the primary tumor with a 1 cm safety margin and bilateral radical lymph node dissection. However, recurrence was observed 1 month after surgery. Radiation therapy and resection were performed for the recurrent tumor. However, distant metastases to both lungs eventually occurred. Here, we describe a rare recurrent case of EOSC of the scalp with distant organ metastasis with a review of the literature.

Background:
We have devised a novel surgical method, termed as temporalis muscle tendonperiosteum (T-P) compound surgical method, by modifying pre-existing techniques. Our method is characterized by elevation of temporalis muscle tendon and the periosteum of the mandibular ramus as a single compound. Here, we describe the concept and clinical outcomes of our method.
Methods:
We conducted both a cadaveric study and a clinical study. First, we used four human cadavers (two males and two females) to confirm the anatomy of the temporalis muscle tendon and availability of sufficient length extension through the elevation of the T-P compound. Moreover, we obtained measurements of the mouth angle and the philtrum angle from a total of six patients (two males and four females) and compared them between preoperatively and postoperatively.
Results:
The mean length of the periosteal portion was measured as 2.43± 0.15 cm (range, 2.2–2.6 cm). There was an improvement in the mouth angle postoperatively as compared with preoperatively (7.2°± 3.0° vs. 14.5°± 4.7°, respectively). Moreover, there was also an improvement in the philtrum angle postoperatively as compared with preoperatively (7.2°± 3.4° vs. 17.2°± 6.5°, respectively).
Conclusion
Our method is a simple, minimally-invasive modality that is effective in achieving good clinical outcomes. Its advantages include an ability to achieve a firm extension of the temporalis muscle tendon as well as a lack of requirement for a donor site that may cause complications.

OBJECTIVE: This study was conducted to develop the computerized memory tests for Korea adults. It also aimed at evaluating the reliability and validity of these tests and providing their normative data. METHODS: Computerized versions of digit span, visual span, auditory verbal learning test, and visual learning test were developed through several steps of preliminary applications and corrections. The test-retest reliabilites of each test was evaluated by the paired t-test and Pearson's correlation coefficient using the data from 27 normal persons. The validity of each test was evaluated by the Pearsons's correlation coefficient between the computerized test scores and the pre-existing cognitive function tests using the data from 48 normal persons. The normative data were obtained from the 150 Korean adults, age 20 to 50, whose educational levels were higher than high school graduate. RESULTS: There were no statistical differences between the means of the test and retest scores. High correlations were also observed between the tests and the retest scores (r ranged from 0.405 to 0.873). The computerized digit span, visual span, and auditory verbal learning tests scores were highly correlated with the pre-existing memory measures. The computerized memory test scores were greatly influenced by the educational level. The visual learning test seems useful, however, it requires methodological refinement. The normative data and guidelines for interpretation were provided. CONCLUSIONS: Clinically applicable computerized memory assessment tools with high reliability and validity were developed. The normative data for the Korean adults aged 20 to 50 were obtained and the guidelines for the interpretation were provided.

Incompetent internal os of cervix is treated with McDonald or Shirodkar cerclage after 14 weeks of gestation. In rare case, after 20 weeks of gestation fetal membrane is bulging into vaginal cavity, but cerclage in that period is risk factor for preterm labor and preterm premature rupture of membranes. So many complications are reported in that period. So many experiences for reducing fetal membranes into uterine cavity were performed. We report a case of amnioreduction in prolapsed fetal membranes after McDonald cerclage, and delivered in 33 weeks of gestation with brief review of literature.
