PURPOSE: This study was aimed to explore and report the short term results of primary cementless hip arthroplasty in treatment of unstable intertrochanteric femur fracture in elderlys. MATERIALS AND METHODS: Between March 2009 and Feburary 2012, 35 arthroplasty cases performed by single surgeon and followed up for more than one year were evaluated. They were 21 females and 14 males with mean age of 78 years (range, 71-92 years). Preoperative evaluation was performed by American Society of Anesthesia score. Retrospective evaluation was performed by operative time, transfusion amount, time to operation days, hospital stay and time to full weight bearing. Clinically, ambulatory ability was checked by Parker and Palmer (P&P) score and function of hip was appraised by Harris hip score (HSS). Radiologically, bone healing of fractured trochanteric fragment and presence of subsidence, stress shielding or osteolysis were checked. RESULTS: Fracture type was 11 cases of A2.2, 18 cases of A2.3 and 6 cases of A3.3. Femoral stems used were 8 cases of rectangular tapered wedge type and 27 cases of fluted modular distal fixation type. P&P score improved from mean preinjury score of 7.1 to mean postoperative last follow-up score of 6.5. Median HHS at last follow-up was 75. Mean time to full weight bearing was 47 days (24-79 days). Postoperative complications were one case of linear periprosthetic femoral fracture and one case of postoperative dislocation. CONCLUSION: Cementless hip replacement arthroplasty could be a good option for unstable intertrochanteric femoral fracture in elderlys.

PURPOSE: Respiratory syncytial virus (RSV) is the most frequent cause of lower respiratory infections in infants and young children. Early detection allows quarantining of infected inpatients to prevent nosocomial transmission and to choose a treatment. To achieve rapid reporting, to facilitate prompt antiviral therapy, and to avoid unnecessary use of antibiotics, an easy, rapid diagnostic method for RSV is needed. We evaluated a lateral flow immunochromatography (RSV Respi-Strip test) and EIA (Enzyme immuno assay) compared to RT-PCR. METHODS: From April 2007 to March 2008, 112 consecutive respiratory specimens (nasopharyngeal aspirates, throat swabs, tracheal aspirates, sputum) from patients who were suffering from the clinical signs and symptoms of respiratory tract infection were enrolled in Busan. A total of 112 patients were tested with RSV Respi-Strip (Corio-BioConcept, Belgium), EIA, and RT-PCR at the same time. RESULTS: Of the 112 specimens tested, the number of children who showed positive results at RT-PCR and Respi-Strip were 45 and 42, respectively. The Respi-Strip rapid antigen test had a sensitivity of 88% and a specificity of 94%. The positive and negative predictive values were 90% and 92%, respectively. The agreement was 83%. CONCLUSION: In our study, the rapid antigen test had as much sensitivity as any method for detection of RSV. The test has many advantages such as easy performance, simple interpretation, and rapid results. If the rapid antigen test is widely applied in the clinical setting, the may be useful for diagnostic and epidemiological studies of RSV infection.

It has been suspected that the cannula of the ultrasonic generator became heated during liposuction, and that the heated cannula might possibly damage the soft tissues such as vessels, nerves and muscles. To confirm these suspicions, the actual temperature of the cannula was measured after being switched on, and the influence of the heated cannula on the soft tissues of 30 rabbits was studied macroscopically and microscopically. When the cooling system of ultrasonic generator was not operated, the temperature of a cannula tip increased to 100degrees C in 10 seconds, and the temperature of a cannula shaft did not increase over 40 degrees C. When the cooling system of the ultrasonic generator was operated, the temperature of the cannula tip increased to 70 degrees C in 20 seconds and to 100 degrees C in 1 minute. The stronger ultrasonic power was, the higher the temperature of the cannula tip was. When the heated cannnula tip touched the muscles, vesseles and nerves directly, the arterial and venous walls were perforated in about 20 seconds and 10 seconds, respectively. Gross changes of the muscles, such as color change and depression of the contacted area, were seen in about 30 seconds, and histological changes occurred in about 3 seconds. When adding the Klein solution, an infiltration solution for increasing the destructive effects of the ultrasound, the onset time of tissue damage was significantly shortened in vessels and nerves, but there was no significant difference in muscles. Although there was no finding of damage by the ultrasonic wave itself on the vessels, nerves, and muscles during ultrasonic liposuction, this study confirmed that the heated cannula could damage vessels, nerves, and muscles. Thus we must try to avoid placing the cannula at certain areas for more than 10 seconds douring the ultrasonic liposuction.

BACKGROUND: To report the radiological and clinical outcomes of internal fixation using distal clavicle hook plates for distal clavicle fractures. METHODS: From April 2008 to December 2012, 32 patients with distal clavicle fractures underwent surgery using an AO hook plate. The reduction was qualified and evaluated according to the radiological findings. The evaluation of the clinical outcomes was performed with the University of California at Los Angeles (UCLA) score, the Korean Shoulder score, and the visual analogue scale (VAS) pain score. RESULTS: By radiological evaluation, we found that 31 of 32 patients showed anatomical reduction and solid bone union. Although we obtained satisfactory UCLA scores, Korean Shoulder Scale scores, and VAS pain scores, 12 cases of complications were present. We found 4 cases of osteolysis of the acromion, 1 case of nonunion, 3 cases of periprosthetic fractures, 3 cases of subacromial pain, and 1 case of skin irritation. We performed re-operations in 2 patients. CONCLUSIONS: To avoid complications associated with clavicle hook plates, choosing the appropriate hook size and bending of the hook according to the slope of the acromion undersurface is critical. Also, we believe that early removal of clavicle plates may help reduce complications.

Medpor, the high density porous polyethylene, which permits rapid ingrowth of both soft tissues and vasculatures, is highly stable but somewhat flexible and is also easy to shape. So it has been often used for plastic and reconstructive surgeries including facial bone fractures, as well as orbital wall fractures. The authors investigated sex and age distribution, causes of injury, combined ocular injuries, and fracture sites of 45 blow-out fractures. And 27 orbital reconstructions was performed by using 0. 85mm thickness Medpor within 2 weeks after injury, if possible. During post-operative follow up, the preoperative diplopia was resolved or decreased in all cases, but the enophthalmos was not completely resolved. Much researches will be needed for choice of Medpor`s thickness or operation methods, and long term stability shoud be approved through further follow up.

BACKGROUND: Management of massive rotator cuff tears can be challenging because of the less satisfactory results and a higher retear rate regardless of the use of open or arthroscopic repair technique. METHODS: We retrospectively analyzed 102 cases of massive rotator cuff tear treated with either open or arthroscopic repair. Open repair was performed in 38 patients; and arthroscopic repair, in 64 patients. The mean age at the time of surgery was 59.7 years in the open group and 57.6 years in the arthroscopic group. RESULTS: The Constant score increased from the preoperative mean of 55.9 to 73.2 at the last follow-up in the open repair group and from 53.8 to 67.6 in the arthroscopic repair group (p<0.001 and <0.001, respectively). The University of California at Los Angeles (UCLA) score increased from a preoperative mean of 17.7 to 30.8 at the last follow-up in the open group and from 17.5 to 28.7 in the arthroscopic group (p<0.001 and <0.001, respectively). No statistically significant difference in the Constant and UCLA scores was observed between the two groups at the last follow-up (p=0.128 and 0.087, respectively). Retear was found in 14 patients (36.8%) in the open group and 39 patients (60.9%) in the arthroscopic group (p=0.024). CONCLUSIONS: Open and arthroscopic repairs of massive rotator cuff tears may provide satisfactory clinical results with no significant difference. However, a significantly lower retear rate was observed for the open repair group compared with the arthroscopic repair group.

Pilar sheath acanthoma is one of the benign follicular hamartoma, with a level of differentiation between trichofolliculoma and dilated pore of Winer. It differentiates toward infundibulum, isthmus, and rarely, sebaceous duct, apocrine, inner root sheath, and hair bulb components. It is a dome-shaped, symmetrical, sharply-circumscribed neoplasm that measures about 1cm in diameter. We herein report a case of pilar sheath acanthoma on the forehead of a 62-year-old male patient.

Pulse oximetry is a noninvasive, reusable device that is being used routinely in anesthesia procedure for monitoring oxygen saturation. This is a very beneficial device that can quickly detect of hypoxia, the most common cause of anesthesia-related death. However, in clinical uses, false desaturation readings are frequently found to be caused by various factors. Such as by the use of intraoperative blue dye, which can falsely decrease oxygen saturation as determined by pulse oximetry. We therefore report our findings concerning prolonged decreased pulse oximetry readings due to the intraoperative use of blue dye subcutaneously.

PURPOSE: To evaluate the influence of a silicone tube on tear drainage in patients with a healed rhinostomy site after dacryocystorhinostomy. METHODS: The subjects of the present study included the patients for whom the removal of a silicone tube was performed after dacryocystorhinostomy for acquired nasolacrimal duct obstruction. The silicone tube was removed after the rhinostomy site was completely healed. The tear drainage function was evaluated using the fluorescein dye disappearance test at the following 3 time points: immediately before, immediately after, and 1 month after silicone tube removal. In addition, a Schirmer test was performed and tear break-up time was measured at each time point. To study the correlation between the measured values and subjective tearing symptoms, self-report questionnaires were given to each patient at his/her last visit. RESULTS: The 3 measured values showed no statistical difference between the 3 time points, immediately before, immediately after, and 1 month after silicone tube removal. When the patients were divided into groups according to their subjective symptomatic changes after silicone tube removal, no group showed statistically significant difference in the 3 measured values before, between, and after silicone tube removal. CONCLUSIONS: In patients with a healed rhinostomy site after dacryocystorhinostomy, the removal of the silicone tube did not induce a change of tear drainage function. Therefore, based on the results from the present study, a silicone tube may not have influence on tear drainage functions.
