The use of interlocking intramedullary nail is accepted one of treatment choices in the comminuted fractures of humeral shaft. The insertion of distal interlocking screws remains technically problematic. The use of intrageon's hands during the procedure. In order to reduce technical difficulty and radiation exposure, it is necessary to compare the rigidity of intramedullary nail according to the number of distal interlocking screws. The purpose of study is to compare the stability of interlocking intramedullary nail according to the number of distal screws by means of torsional compliance measurements in the simulated humeral shaft fractures. Simulated fractures were made in 20 humora from 10 cadavera at the mid-junction of humeral shaft. All humora were fixated with titaium humeral nail system. Interlocking screws were placed at proximal and distal screw holes by standard procedure. Group I consisted of 10 humora fixated with one distal interlocking screw and group II consisted of 10 humora fixated with two distal intterlocking screws. Torsional compliance was measured with single-end of 10 humora fixated with two distal interlocking screws. Torsional compliance was measured with single-end double arm torquing machine. The torsional compliance analog was 0.0294+/-0.0033 mm/N mm for one screw and 0.0241+/-0.0045 mm/N mm for two distal screws. The torsional compliance analog between two groups was found to be statistically insignificant(p=0.23). In conclusion, One distal interlocking screw was not inferior to two interlocking screws in terms of biomechanical characteristics, especially torsional compliance analog.

PURPOSE: To evaluate the therapeutic effect and safety of mycophenolate mofetil (MMF) on chronic uveitis in Korean patients. METHODS: This study included 25 patients with chronic uveitis who used MMF and were followed up more than 6 months in 2 referral centers from 2010 to 2014. The medical records were analyzed retrospectively. The therapeutic effect was assessed based on control of inflammation, corticosteroid sparing effects, and discontinuation of MMF, and the safety was assessed based on side effects. Control of inflammation was defined as no active inflammation observed on at least 2 consecutive visits 28 days apart or more. RESULTS: The 25 patients consisted of 18 males and 7 females. The mean age of the patients was 47.52 years. The etiology of uveitis was as follows: Behcet's disease in 15 patients (60%), Vogt-Koyanagi-Harada disease in 4 (16%), sympathetic ophthalmia in 2 (8%), systemic lupus erythematosus in 1 (4%), and idiopathic uveitis in 3 (12%). Anatomic classification was anterior uveitis in 20% and posterior uveitis or panuveitis in 80% of patients. Complete control of inflammation was achieved in 44% and 50% of patients within 6 months and 1 year, respectively. Systemic corticosteroid dosage was reduced to 10 mg of prednisone or less while maintaining sustained control of inflammation in 36% and 45% of patients for 6 months and 1 year, respectively. MMF was discontinued in 3 patients (12%) due to side effects and in 2 patients (8%) due to lack of effectiveness. CONCLUSIONS: MMF was effective and side effects were uncommon when managing chronic uveitis in Korean patients.

BACKGROUND: In a study, iris color was positively associated with skin melanin content. So it could be assumed that iris color has a close relationship with skin color. But until recently, classification system of iris color has been subjective and not suitable especially for Asian population for their relative homogeneity of iris color. OBJECTIVE: The purpose of this study was to devise an objective and quantitative method to measure iris and skin color quantitatively and to assess the relationship and its significance. METHODS: We devised photographic system composed of digital camera and tungsten lamp with color temperature conversion filter to acquire adequate iris images for colorimetric investigations. The reference CIELAB coordinates of color chart recorded with reflectance spectrophotometer were compared statistically with computed CIELAB coordinates from digital images in order to find equations for calibrating CIELAB values. To find the dermatological significance, we took pictures of 47 Korean patients with various conditions. They were evaluated with regard to iris color, color of sun-exposed and sun-protected skin. RESULTS: The images obtained with this system were enough to be used for the assessment of iris and skin color. And, it was possible to quantify the iris color, skin color and its difference in colorimetric ways using the methods in this study. Lightness (L*) of sun-exposed skin is decreased to the age. L* of iris has a positive correlation with L* of sun-exposed skin. L* of iris was positively correlated with a* and b* of iris respectively. The relations were very similar with those between L* of iris and each of a* and b* of sun-protected skin. CONCLUSION: Iris color could be assessed by using their images colorimetrically obtained by our method. As L* of iris color has the similar relations with a* and b* in both iris and sun-protected skin, the iris color would be a clue to look for and define the constitutional skin color.

PURPOSE: Bony resection of the proximal medial tibia, an alternative technique for soft tissue balancing in total knee arthroplasty (TKA), was compared to the conventional medial soft tissue release technique. MATERIALS AND METHODS: From June 2005 to June 2007, we performed 40 TKA in 27 patients with > or =10degrees tibio-femoral varus deformity. The conventional, medial soft tissue release technique was applied in 20 cases and bony resection of proximal medial tibia in the other 20 cases (vertical osteotomy group). Total operation time, knee range of motion (ROM), hospital for special surgery (HSS) scores, and tibio-femoral medial-lateral gap ratio in 0degrees, 90degrees, and 130degrees flexion at postoperative 6 months were compared between the groups. RESULTS: The total operation time was shorter in the vertical osteotomy group. Tibio-femoral medial-lateral gap ratio in 130degrees flexion was closer to 1 in the vertical osteotomy group (p=0.000). There was no significant difference in the ROM, HSS score, or tibio-femoral medial-lateral gap ratio in 0degrees and 90degrees flexion at postoperative 6 months. CONCLUSIONS: In severe varus knees, bony resection of proximal medial tibia can be considered as an alternative technique, in order to decrease total operation time and to obtain medial-lateral, soft-tissue balance in deep flexion.

Purpose: Significant improvements have been made in the surgical treatment of rectal cancer with a higher sphinctersaving rate without compromising oncologic results. There have been studies about the quality of life of rectal cancer patients after surgery. However, no study has reported the long-term annual incidence of depression after rectal cancer surgery according to stoma status. The objective of this study was to determine the annual incidence of depression after rectal cancer surgery and the factors affecting it, especially the prevalence of depression according to the presence or duration of a stoma. Methods: Using the Korea National Health Insurance Service database, patients who underwent radical surgery for rectal cancer from 2002 to 2019 were searched. We analyzed the incidence and risk factors of depression in patients who underwent radical surgery for rectal cancer according to stoma status. Results: Annual incidence of depression in rectal cancer patients was decreasing annually for 15 years after surgery. There was no statistically significant difference in the incidence of depression according to the stoma status. However, the diagnosis of depression within 1 year after surgery was statistically significantly increased in the permanent stoma group. Conclusion There was no difference in the overall incidence of depressive disorders among patients with rectal cancer based on their stoma status. However, a permanent stoma seems to increase the incidence in the first year after surgery. Education and intensive assessments of depressive disorders in patients with permanent stoma within 1 year after surgery are needed, particularly for female patients who are under 50 years old.

Acral persistent papular mucinosis (APPM) is a rare subtype of localized lichen myxedematosus, which involves only the extensor surfaces of the hands, wrists and the distal part of forearms. Some subtypes of lichen myxedematosus including APPM have been reported with increased frequency in a patient with human immunodeficiency virus (HIV) infection. We describe a 31 year-old male patient with an HIV infection who presented with discrete, flesh-colored papules on the extensor surfaces of the wrists and the distal part of the forearms. Histopathologic findings revealed focal deposition of mucin in papillary and mid dermis that spared a small grenz zone. The lesions showed spontaneous regression after starting highly active antiretroviral therapy (HAART). We report a rare case of APPM in a patient with HIV infection which showed spontaneous regression with HAART, suggesting that APPM may represent one of the cutaneous markers of HIV infection.

A 20-year-old male was admitted to our hospital due to a cosmetic problem of gynecomastia. He received a surgical resection of subcutaneous fat through an incision in the periareolar area under general anesthesia. On the postoperative fifth day, he complained of intraoral pain due to an oral ulcer. He was prescribed benoxinate at 4 mL (12 mg) for use by gargling, but instead he injected it intravenously by himself. He experienced severe tremors in the extremities, chest discomfort, and palpitation immediately after injection, and sinus tachycardia was noted on the electrocardiogram. We managed his symptoms by hydration with normal saline and oxygen supplementation. Seven hours later, his symptoms had subsided, and no further complications were observed.

During the early stage of postherpetic neuralgia, an epidural block on the affected segment is helpful in controlling pain and preventing progression to a chronic state. The main neurologic complication following an epidural block is cord compression symptom due to an epidural hematoma. When neurologic complications arise from an epidural block for the treatment of postherpetic neuralgia, it is important to determine whether the complications are due to the procedure or due to the herpes zoster itself. We report a case of a patient who was diagnosed with herpes zoster myelitis during treatment for postherpetic neuralgia. The patient complained of motor weakness in the lower extremities after receiving a thoracic epidural block six times. Although initially, we believed that the complications were due to the epidural block, it was ultimately determined to be from the herpes zoster myelitis.
