The authors performed microsurgical reconstruction by free cutaneous or myocutaneous flaps transfer in 104 cases, who were sustained of extensive soft tissue injuries on their extremities by accident. These 104 cases were operated in 6 years from 1980 to 1986 and were consisted of 47 cases of latissimus dorsimyocutaneous free flaps, 36 cases of scapular free flaps, 18 cases of dorsalis pedis sensible free flaps, and 3 cases of groin flaps. Most of them were males(80 cases) and were in third decade(28 cases). The youngest case was 2-year-old baby and the oldest one was 76-year-old woman. The traffic accident was the most frequent cause of injuries(55 cases), and the others were burn, industrial injuries, and cultivator accidents. Most of the microsurgical reconstruction were performed in lower extremity injuries(81 cases), especially below the ankle joints(65 cases). The average dimension(width and length) of free flaps were 7.3×14.3cm in latissimus dorsi free flaps, 5.6×8.2cm in scapular free flaps, and 4.5×5.9cm in dorsalis pedis free flaps. The dorsalis pedis free flaps were successful in 100%, the scapular free flaps were in 83.3%, the latissimus dorsi myocutaneous free flaps were in 89.4%, and the groin free flaps were in 33.3%, And the overall viability of 104 free flaps was 87.5%.

PURPOSE: Because cryptorchid testes are known to undergo histopathologic changes affecting development, maturation, and tertility, early surgical correction is usually recommended. However there are differing opinions concerning whether retractile testes are affected by similar changes and also whether there is a need for surgical treatment. We aimed to assess the histopathologic changes in retractile testis by studying the changes in testes artificially placed back in the abdomen after they have descended to scrotum in experimental rat models. MATERIALS AND METHODS: Male Sprague-Dawley rats were divided into 3 groups; a control group(controls), prepubertal ascent group (P) in which testis were placed back intraabdominally by bilateral inguinal canal obstruction at 6 weeks, a neonatal group(N) in which intraabdminal testis was induced by bilateral inguinal canal obstruction at birth. The relative weight of the testis, morphology of the seminiferous tubules including Leydig cells, tubular degeneration phase(TDP), spermatogonia per tubules(S/T), and Sertoli cell index (SCI) of these three groups were analyzed and compared. RESULTS: The relative weight of testis was significantly decreased in the group of N(0.0016+/-0.001) and P(0.0015+/-0.0002) compared to controls(0.0037+/-0.0002) (p<0.05). The S/T value was also decreased in P(2.05+/-18.2) and N(73.2+/-32.4) when compared to controls (360.2+/-21.3). Similar changes were observed in SCI of both P(64.5+/-6.4) and N (91.2+/-14.2) when compared to controls (227.9+/-31.1). Only minority of N and P showed higher TDP values. However, although statistically insignificant, TDP was increased in both P and N when compared to controls. The Leydig cells in N and P showed cellular distortion and hypertrophy. CONCLUSIONS: This study demonstrate that prepubertal ascent, similar to that of innate cryptorchid testis, also can induce histopathologic changes such as changes in testicular seminiferous tubule, decrease in the S/T value and decrease in SCI value. Our findings supports that hypothesis that retractile testis may cause histological damage thus surgical correction may also be warranted similar to in case of genuine cryptorchism.

BACKGROUND: Blowout fracture is one of the most common facial fractures, and patients usually present with accompanying ocular complications. Many studies have looked into the frequency of persistent ocular symptoms, but there is no study on assault patients and related ocular symptoms. We evaluated the incidence of residual ocular symptoms in blow-out fractures between assaulted and non-assaulted patients, and sought to identify any connection among the degree of enophthalmos, defect size, and assault-related injury. METHODS: A retrospective review was performed for any patient who sustained a unilateral blowout fracture between January 2010 to December 2014. The collected data included information such as age, gender, etiology, and clinical ocular symptoms as examined by an ophthalmologist. This data was analyzed between patients who were injured through physical altercation and patients who were injured through other means. RESULTS: The review identified a total of 182 patients. Out of these, 74 patients (40.7%) have been struck by a fist, whereas 108 patients (59.3%) have sustained non-assault related injuries. The average age was 36.1 years, and there was a male predominance in both groups (70 patients [94.6%] in the assaulted group and 87 patients [80.6%] in the non-assault group). Diplopia and enophthalmos were more frequent in patients with assault history than in non-assaulted patients (p <0.05). Preoperatively, 25 patients (33.8%) with assault history showed diplopia, whereas 20 patients (18.5%) showed diplopia in the non-assaulted group (p <0.05). Preoperative enophthalmos was present in 34 patients (45.9%) with assault history, whereas 31 patients (28.7%) showed enophthalmos in the non-assaulted group (p <0.05). CONCLUSION: Patients with an assault history due to a fist blow experienced preoperative symptoms more frequently than did patients with non-assault-related trauma history. Preoperative diplopia and enophthalmos occurred at a higher rate for patients who were assaulted. Surgeons should take into account such characteristics in the management of assaulted patients.

Primary tumors of the heart are rare. Half of all cardiac tumors are myxoma of which 20% are located in the right atrium. Especially multiple myxomas in the cardiac chamber were rarely reported. Clinically, myxomas present with various manifestations due to obstruction to blood flow, embolization,and constitutional changes. The association of pulmonary emboli and right atrial myxoma has been well documented but pulmonary emboli are more likely to be asymptomatic, misdiagnosed, or diagnosed late than peripherally-sited emboli. We report a case of multiple right atrial myxomas complicating pulmonary emboli in a 73-year-old man who had features of pulmonary embolism and was found to have multiple right atrial myxomas.

BACKGROUND: The prevalence and clinical characteristics of psoriatic arthritis (PsA) in patients with psoriasis are not well described in Asian populations, including Koreans. OBJECTIVE: The purpose of this study was to investigate the prevalence of PsA by using the classification of psoriatic arthritis (CASPAR) criteria on the basis of physical examination only, as well as its correlation with psoriasis severity and other medical conditions including nail psoriasis. METHODS: A single-center, cross-sectional observational cohort study was conducted, and the included patients were evaluated for PsA according to the CASPAR criteria. The psoriasis area severity index (PASI) and the nail psoriasis severity index (NAPSI) were calculated. RESULTS: The prevalence of PsA in patients with psoriasis in Korea was 13.5%. When performing logistic regression, hyperlipidemia and localized pustular psoriasis were found to be significant predictors of PsA. The PASI score was significantly higher in PsA patients than in those with psoriasis alone (p=0.014). Psoriatic nail involvement was found in 85.5% of the study population, and all PsA patients had nail psoriasis. The mean NAPSI score was higher in patients with PsA; however, the difference was not statistically significant. CONCLUSION: There was a close relation between psoriasis severity and PsA, although nail psoriasis severity was not related to PsA status. Dermatologists can diagnose PsA from current physical findings by using the CASPAR criteria. To validate the CASPAR criteria for PsA diagnosis, the definition of nail psoriasis clinical types and severity in the CASPAR criteria should be reviewed again.
