Osteochondromas are one of the most common benign bone tumors usually involving extraarticular metaphysis of long bone. Solitary intra-articular osteochondroma arising from the elbow joint has rarely been reported. We present a case of 23-year-old female who had pain and limited motion of the left elbow as a result of intraarticular osteochondroma of the distal humerus. Arthroscopic excision of the osteochondroma yielded complete relief of symptoms. Absence of recurrence was confirmed radiographically at two years after surgery. To the best of our knowledge, this is the first report of osteochondroma of the elbow successfully treated arthroscopically.

BACKGROUND: Few studies have reported the results of arthroscopic coracoplasty concomitantly conducted with subscapularis tear. Therefore, this study was conducted to examine and compare the outcomes of arthroscopic subscapularis repair after arthroscopic coracoplasty using either the subacromial approach or rotator interval approach. METHODS: We retrospectively reviewed 51 patients who underwent coracoplasty with subscapularis repair. The patients were grouped according to whether the subacromial approach group (24 patients) or rotator interval approach group (27 patients) was used during coracoplasty. Preoperative and postoperative visual analogue scale scores, American shoulder and elbow surgeons scores, Korean shoulder scores, and range of motion (ROM) were assessed. Assessment of repaired rotator cuff tendon integrity was performed at 1 year after surgery using either magnetic resonance imaging or ultrasonography. RESULTS: At final follow-up, overall functional scores and ROM improved significantly in both groups when compared with preoperative values (p>0.05). The re-tear rates were not significantly different between groups; however, the rotator interval approach group showed a significant increase in ROM compared with that in the subacromial approach group (p<0.05). CONCLUSIONS: Arthroscopic coracoplasty conducted concomitantly with subscapularis repair can provide a satisfactory outcome. There were no significant differences between the two approach groups regarding final functional scores and re-tear rates. However, the rotator interval approach group showed a greater increase in ROM at final follow-up, especially in external rotation.

PURPOSE: To determine the characteristics of benign breast calcifications on mammogram. MATERIALS AND METHODS: Benign breast calcifications on mammograms of 25 patients, which were confirmed by needle localization and excisional biopsy(15 cases), cytology(1 case), or follow-up study(9 cases), were retrospectively analysed according to size, shape, number, distribution, and density. RESULTS: The size of benign breast calcifications was uniform in 4 cases (16%), and variable in 21 cases (84%). The shape of calcifications was round or oval in 18 cases(72%), linear or branching pattern in 6 cases (24%), and irregular in 1 case(4%). The number of calcifications was 2-5 in 7 cases(28%), and over 6 in 12 cases(48%). The distribution of calcifications was focal in 13 cases(52%) and diffuse in 12 cases(48%). The density of calcification was homogenous in all 25 cases(100%). CONCLUSION: Analysis of number, shape, size, and distribution is helpful for the diagnosis of benign breast calcifications. However the homogenous density of the calcification is suggested to be the most helpful criterion for the diagnosis of benign breast calcifications.

PURPOSE: To compare the results of cataract surgery between continuous mode and WhiteStar mode the latter is known to induce less heat production in the anterior chamber METHODS: The patients were recruited prospectively since May 2003. They were consecutively assigned to the continuous mode group and the WhiteStar mode group according to preoperative lens color grading in order to equally distribute the lens color grading in both groups. Ultrasound time, operating time, and loss of endothelial cells were evaluated. RESULTS: There was a positive correlation between lens color and ultrasound time and between lens color and operating time (p<0.01). There was no significant difference between the two groups in ultrasound time, operating time or loss of endothelial cells. CONCLUSIONS: There was no remarkable advantage in cataract surgery using WhiteStar mode compared with using conventional continuous mode.

It is generally considered that enteral feeding is superior to parenteral nutritional support. Thus enteral meal should be given whenever patients have proper gastrointestinal function to take enteral feeding. Because the morbidity and mortality for surgical jejunostomy have been reported as high as 50% and 10% respectively, direct percutaneous endoscopic jejunostomy has been developed to reduce the morbidity and mortality. A 55-year-old male patient, who was suffering from dysphagia and oropharyngeal aspiration, was transferred to the division of gastroenterology to be done permanent enteral feeding. His stomach was resected (subtotal gastrectomy with billroth II anastomosis) due to peptic ulcer hemorrhage 10 years before. We performed direct percutaneous endoscopic jejunostomy without any complication. Herein, we report a successful case.

Though trichogenic tumors were classified as trichoblastoma, trichoblastic fibroma, trichogenic trichoblastoma and trichogenic myxoma by Headington(1970), their true classification depends upon the epithelial and mesodermal component as well as evidence of their induction. Because of the rarity of hair germ cell tumors their classification is still controversial. In this report, we describe a case of trichogerminoma which is not included in the above classification. The trichogerminoma was first described by Sau et al. in 1992 and characterized by its morphologic pattern of germinal centers and lymphoid follicle-like structures in the nests of trichoblasts. Herein we reporte a tumor which arose on the skin on the back of a 51-year-old man and presented as a sharply circumscribed mass(4.5x2.0x1.5 cm) involving both the dermal and subcutaneous tissues without any epidermal connection. The tumor had many germinal center-like structures in the basaloid trichoblasts. Lobular cell nests were separated by variable amounts of stroma, but no horn cyst were noted. The germinal center-like cells showed early differentiation of hairs, resembling early hair bulbs. Trichogerminoma is considered to be a type of tumor located between trichoblastoma and trichoblastic fibroma.

PURPOSE: To describe a case of unilateral corneal keloid and present the clinical and histopathological findings and the management. METHODS: A 23-year-old Asian male patient was examined for a white spot on the left cornea that had been present since birth. On biomicroscopic examination, a well-demarcated vascularized corneal mass was found located nasal to the center. The pupil was displaced superiorly, and gonioscopic examination showed peripheral iridocorneal adhesion at 12 o'clock. The patient underwent penetrating keratoplasty. RESULTS: Histopathologic study showed a variously thickened epithelial layer, an absence of Bowman's layer, subepithelial fibrovascular hyperplasia, and an absence of dermal elements. These histopathologic findings suggested a congenital corneal keloid. The central graft cornea remained clear at 18 months after surgery and the patient was satisfied with the result. CONCLUSIONS: Penetrating keratoplasty may be an effective surgical option for congenital keloids in young adult patients.

Purpose: Post-fracture sleeping disorders can lead to a deterioration of mental and physical health and delay recovery to pre-fracture status. Here, an analysis was conducted to determine if sleep disturbance is a risk factor for delirium in patients older than 60 years of age with surgically treated proximal femoral fractures. Materials and Methods: This retrospective study included 316 patients with surgically treated proximal femoral fractures between January 2014 and December 2016; 33 patients were removed from analysis due to exclusion criteria. Confirmation of delirium was made by a neurologist upon consultation for cognitive impairment and sleeping disorders were confirmed by a doctor or nurse based on the Pittsburgh sleep quality index. Potential risk factors other than a sleep disorder (e.g., history of cognitive impairment, medical illness, preoperational levels of albumin and hemoglobin, transfusion) were also analyzed as variables for the development of delirium. Results: The sensitivity and specificity of a sleeping disorder as a risk factor for the development of delirium were 0.75 and 0.76, respectively; the positive and negative predictive values were 0.64 and 0.93, respectively. A sleeping disorder was significantly related to the development of the delirium (odds ratio adjusted for age, sex and body mass index was 5.78, P<0.01). In those with a history of cognitive impairment, the adjusted odds ratio for the development of delirium was 6.03 (P<0.01). Conclusion Sleeping disorders occurring after a surgically repaired proximal femoral fracture in patients 60 years of age or older could be an independent predictive factor of delirium.
