PURPOSE: Objective measurements of knee of flexor and extensor strength using isokinetic equipment and function after total knee arthroplasty (TKA) were evaluated until postoperative 12 months. MATERIALS AND METHODS: The control group constituted of 15 persons who were of same age and weight without knee problems. Most of the patients (70%) were operated on both knees simultaneously. The patient group consisted of constituted with 20 patients (34 cases). Isokinetic testing (Cybex) of knee flexor and extensor strength of knee and functional evaluation by HSS score was performed preoperatively and at 3, 6, 12 months postoperatively. RESULTS: The peak torque of the knee extensor and flexor muscle in the patient group was decreased by 17-41% compared to the control group. Especially, the peak torque of extensor was more decreased than flexor muscles. At postoperative 12 months, the peak-torque values of hamstring and quadriceps were able to attain the same strength levels of the preoperative knee. According to the grade of the Hospital for Special Surgery knee rating scales by Insall, 28 cases (82 %) in the patient group could obtain good result at postoperative one year. CONCLUSIONS: Exercises to increase the strength of extensor should be emphasized in the rehabilitation programs after TKA

In an open reduction of the mandibular angle fracture, it is crucial to approximate each fracture segment as closer as possible for the reduction of the healing period. In this case report, we proposed a new technique for the mandibular angle fracture. This was designed to minimize the gap between two separated segments using mini-implants and surgical wires. Mini-implants were placed around the fracture line, followed by wire ligation to minimize the fracture gap. And then internal fixation was easily employed with plates and screws. The advantages of this technique were reduced time for operation, the promotion of healing, rapid functional recovery, and few complications.

This study investigated that the effect of rewetting agent on dentinal microtensile bond strength (microTBS). Human molars were sectioned to expose the superficial dentin surfaces. Samples were divided into two groups according to type of adhesives-Single Bond (S) and One-Step (O)], and again subdivided into five groups by different dentin surface treatment-dry for 15s (D), blot dry (BD) or dry for 15s, and rewet with different rewetting agents [distilled water (DW), Gluma Desensitizer (GD) and Aqua-Prep (AP)] for 30s. After application of adhesive, composite resin was built up on the bonding surface. Each tooth was sectioned to obtain stick with 1 mm2 cross sectional area and the microTBS was determined by EZ test. In the S group, the mean microTBS of GD, AP and BD group was significantly higher than that of DW and D group (p < 0.05). In the O group, the mean microTBS of AP, GD, BD and DW group was significantly higher than that of D group (p < 0.05). The data suggested that Gluma Desensitizer and Aqua-Prep could be successfully used as rewetting agents, and Distilled water could be acceptable in aceton based adhesive system only.

Traumatic carotid-cavernous fistula(CCF) is a rare complication of moderate to severe head injury. A series of 15 traumatic carotid-cavernous fistulas has been analyzed and 13 cases have been treated with 3 different methods:direct obliteration through pterional approach(5 cases), ligation of internal, common and external carotid artery in the neck(2 cases), occlusion of CCF with detachable balloon technique(6 cases). The remaining 2 cases were treated by conservative procedures. There were 12 cases(80%) with skull fractures, the majority of which(10 cases) had frontal vault and basal skull fractures. The results of each method were as follows:1) Among the 5 direct obliteration procedure groups, we got satisfactory results in only 2 cases(40%), and the other 2 cases needed additional instantaneous carotid trapping procedures, which corrected the fistula. Internal carotid artery patency was also preserved in 2 cases(40%). 2) Among the 2 cases of carotid trapping group, only 1 case(50%) improved to good. 3) Amo ng the detachable balloon group, 5 cases(83.3%) recovered to good or corrected. Carotid patency was preserved in 4 cases(67.7%). As a result, initial treatment modality of CCF should be detachable balloon technique because of good preservation of carotid patency, better result, simplicity, and safety compared with other operative methods.

OBJECTIVETo summarize and critically evaluate the evidence for and against the effectiveness of Eastern-Western integrative medicine (EWIM) for health care compared to Eastern medicine (EM) or Western medicine (WM) alone.

METHODSSystematic searches were conducted on five Korean medical databases. Manual searches were also conducted through nine major Korean medical journals. Prospective randomized clinical trials (RCTs) were included if EWIM was tested for any type of conditions compared to EM or WM.

RESULTSThere were one hundred forty-one possibly relevant studies were identified, and seven RCTs were included. The risk of bias was high in most studies. The EWIM methods were compared with EM or WM in patients with pain conditions in four studies. These studies showed favorable effects of EWIM on pain reduction in patients with shoulder pain and chronic headache compared with EM, while the other RCTs failed to do so in traffic injury patients. Two studies tested EWIM in patients with Bell's palsy compared with EM and found acute functional improvement. An RCT comparing EWIM with WM in patients with acne showed a significant difference.

CONCLUSIONThe results of our systematic review suggest that there is limited evidence for the superiority of EWIM over EM or WM in the treatment of pain and acute symptom improvement in patients with Bell's palsy. The evidence from our analysis was limited from the low number of RCTs included and the high risk of bias. Future RCTs appear to be warranted.

Acquired digital fibrokeratoma is very a rare, benign, fibrous, and hyperkeratotic skin tumor that develops most frequently on the finger or toe. The tumor usually occurs in adults as a solitary, dome-shaped lesion. Sometimes, it appears as a rudimentary supernumerary digit and may be misdiagnosed as an accessory nail (double nail) or verruca vulgaris. The pathophysiology of an acquired digital fibrokeratoma is unknown. On the other hand, trauma has often been proposed as a predisposing factor for an acquired type of digital fibrokeratoma. This paper reports a case of trauma-related acquired digital fibrokeratoma presenting as a supernumerary digit and nail in a 36-year-old male.This case is presented with a 0.5 cm×0.4 cm×1.3 cm sized, firm, hyperkeratotic, protruding mass over the left second finger nail.

This study evaluated the influence of application time of self-etching primers on microtensile bond strength (microTBS) to dentin using three self-etching primer adhesive systems. Dentin surfaces were exposed from forty-eight human molars. They were conditioned with three self-etching primers (Clearfil SE Bond [SE], Unifil Bond [UF], Tyrian SPE + One Step Plus [TY]) and different primining times (10s, 20s, 30s and 40s). Composite resins were bonded to dentin surfaces and specimens were made. microTBS was tested and statistically compared using by one-way ANOVA and Tukey's Test The results of this study presented that priming time for 10s in SE and UF groups and for 30s and 40s in TY group was highly decreased microTBS to dentin.
