The types of patellar component of total knee replacement prostheses are dome-shape, metalbacked, anatomically shaped, and press fit condylar type, etc. The fixation of inset patella type is achieved with bone cement supplemented by a central peg and a small extended flange around the circumference, providing resistance to torsional and shear loads. From October 1990 to June 1992, 53 cases in 40 patients had total knee arthroplasties. Ortholoc II implant was used in all patients. Cementless femoral and tibial component were used. But, cement was used in patellar component. The average follow up was 29 months(range 21-40 months). There were 37 women and 3 men and the average age was 51 years(range 22-71 years). The diagnosis of 40 patients was osteoarthritis in 25, rheumatoid arthritis in 9, infection sequelae in 6. For alignment of the patellar and congruency of the patellofemoral joint, additional retinacular release was done in 7 cases. The average preoperative Hospital for Special Surgery(H.S.S) knee rating score was 50.7 point, which improved to 89.4 point at last follow up. Postoperative patellar pain was 4 cases. In the roentgenorgraphic follow up, ratellar subluxation was 2 cases and lateral tilting of the patella was 5.9 degrees in 10 cases. The average patellar depth was 20.8mm preoperatively and 21.6mm postoperatively. In the Merchant's view, the preoperative lateral patellofemoral angle of Laurine was average 14.3 degree, which changed to average 16.4 degree at last follow up, and the preoperative Merchant's congruence angle was average 14 degrees, which decreased to average

Patellofemoral complications are the most frequent problems in total knee arthroplasty. In the literature, the subject of patella resurfacing and nonresurfacing is controversial. Twenty-seven osteoarthritic patients who received bilateral total knee prostheses were studied to evaluate the advantages and disadvantages of patella resurfacing prospectively. Only patients with mild patellofemoral disease were included in the study. The Ortholoc modular implant was used in all cases. Cementless femoral and tibial component were used. But, if we resurfaced the patella, cement was used. In all patients, patella resurfacing had been done in the left knee but not in the right knee. For the clinical analysis, We used Knee Rating Score of the Hospital for Special Surgery(HSS), For the roentgenographic analysis, We used Laurin's lateral patellofemoral angle & Merchant's congruence angle. In the follow up, blind test for patellar pain was performed to compare between right and left knee joint clinically. The average age was 61 years(range 28-72 years) and the average follow up was 21 months(range 12-27 months). Preoperative ROM was 104.4 degrees in right side and 106.7 degrees in left side. Postoperative ROM was 112.7 degrees in right side and 109.6 degrees in left side. Preoperative HSS Knee Rating Score was 53.1 point in right side and 54.8 point in left side. Postoperative HSS Knee Rating Score was 81.5 point in right side and 81.2 point in left side. In the plain knee AP view, preoperative tibiofemoral angle was varus 7.0 degrees in right side and varus 5.6 degrees in left side. Postoperative tibiofemoral angle was valgus 5.1 degrees in right side and valgus 4.9 degrees in left side. Preoperative Merchant's congruence angle was 14.9 degrees in right side and 15.3 degrees in left side. Postoperative Merchant's congruence angle was

The Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is comprised of vaginal atresia with other variable Mullerian duct abnormalities. Its features include an absent or very short vagina and a uterus that can be absent or immaturely formed. Female with MRKH syndrome have functioning ovaries, normal external genitalia and the typical 46, XX, karyotype. MRKH syndrome is the second most common cause of primary amenorrhea, usually remains undetected until the patient presents with primary amenorrhea despite normal sexual female development. We report a case of MRKH syndrome, associated with ovarian follicular cyst, in a 14-years-old girl who visited for primary amenorrhea and sexual precosity.

A 16-year-old girl was transferred to the department of thoracic and cardiovascular surgery because of a spontaneous pneumothorax with prolonged air leakage. Chest computed tomography demonstrated a cystic lesion measuring 2×3 cm and involving the left upper lobe. Left upper lobectomy was performed via video-assisted thoracoscopic surgery. A pathologic examination of the specimen revealed a mesenchymal cystic hamartoma. Despite the rarity of pulmonary mesenchymal cystic hamartoma, it should be considered a potential cause of pneumothorax for patients with a large pulmonary cyst. Further, surgical resection must be considered because serious complications such as hemothorax, hemoptysis, and malignant transformation have been reported.

Purpose: To analyze the repeatability of manual measurement of foveal avascular zone (FAZ) area in an optical coherence tomography angiography (OCTA) image in high myopia. Methods: This study comprised patients with high myopia and controls. Two consecutive FAZ areas of the superficial and deep capillary plexus were obtained using OCTA. The intraclass correlation coefficient (ICC) and coefficient of variation (CV) were assessed, and univariate and multivariate generalized linear mixed models were conducted to identify factors related to repeatability. Results: Thirty eyes with high myopia and 34 eyes of healthy subjects were included in the study. The mean age in high myopia and control subjects was 55.5 and 60.8 years, respectively, the mean spherical equivalent was −9.98 and −0.55 diopters, and the mean axial length was 28.0 and 23.9 mm. The ICCs of FAZ area of the superficial capillary plexus (SCP) were 0.891 and 0.919, while the CVs were 8.8% and 8.5%. In measurement of the deep capillary plexus, the ICCs were 0.788 and 0.907, while the CVs were 11.2% and 11.0%, which were acceptable but exhibited lower repeatability than those of SCP. Multivariate analyses showed that older age (p = 0.030) and greater axial length (p = 0.005) were significantly associated with lower repeatability of SCP FAZ area measurements. In addition, greater axial length (p = 0.044) was a significant factor for lower repeatability of deep capillary plexus FAZ area measurements. Conclusions Manual measurement of FAZ area using OCTA exhibited relatively good repeatability for high myopia. Age and axial length affected repeatability and should be considered when analyzing FAZ areas in high myopia patients.

Acute bilateral renal cortical necrosis (BRCN) is a rare cause of renal failure. It has been reported that contrast-enhanced computed tomography provides characteristic findings of BRCN which correlates well with the histopathology making it an important non-invasive diagnostic modality during early phase of BRCN, improving survival rate and prognosis with early diagnosis and treatment. This report presents a case of 73-year old woman with BRCN due to hemolytic uremic syndrome. The patient recovered from anuria and showed complete recovery to normal renal function of her age and serum creatinine level after early initiation of hemodialysis. Furthermore, a normal radiologic finding of kidney was obtained after 52 days from onset of the disease by contrast-enhanced computed tomography. At present, she is preserved within the normal range renal function without renal replacement therapy.

Background/Aims: The optimal treatment for acute malignant obstruction of the proximal colon (MOPC, proximal to the splenic flexure) remains challenging. Emergency resection, the traditional modality for MOPC, has shown significantly high mortality and morbidity rates, according to recent studies. This study aimed to investigate the clinical outcomes of stent vs stoma as a bridge to curative surgery for MOPC. Methods: This retrospective cohort study included 72 patients who underwent endoscopic placement of a self-expanding metallic stent (SEMS) or loop ileostomy for MOPC at six referral centers between January 2011 and July 2021. Clinical and pathological characteristics, procedure-related complications, and long-term mortality rates after curative surgery were analyzed. Results: During a mean follow-up period of 32 months, 30 patients (41.7%) underwent ileostomy preferentially for more proximal cancer, complete obstruction, and advanced tumor stage compared to the SEMS group. No difference was found in procedure-related complications, but five deaths were observed after ileostomy. Survival analysis for 5-year mortality after curative surgery showed no significant difference between the bridge modalities (log-rank p = 0.253). Conclusions In this study, SEMS as a bridge to surgery showed relatively safe results in terms of post-procedural mortality. However, these results should be considered when performing ileostomy in patients with more advanced malignant obstruction.
