Aneurysmal bone cyst uncommonly involves the pubic bone and tends to grow eccentrically and thin out overlying cortex. In the following case report, a 19-year-old male patient visited out hospital, because of dull pain in his left groin. He was diagnosed as aneurysmal bone cyst originated from the superior pubic ramus by CT guided needle biopsy. Transcatheter arterial embolization was effective in the treatment of this lesion such as complete consolidation after the procedure. At present, 2 years follow-up, no problem was noted at weight bearing as well as hip function or recurrence.

In data analysis, given that various statistical methods assume that the distribution of the population data is normal distribution, it is essential to check and test whether or not the data satisfy the normality requirement. Although the analytical methods vary depending on whether or not the normality is satisfied, inconsistent results might be obtained depending on the analysis method used. In many clinical research papers, the results are presented and interpreted without checking or testing normality. According to the central limit theorem, the distribution of the sample mean satisfies the normal distribution when the number of samples is above 30. However, in many clinical studies, due to cost and time restrictions during data collection, the number of samples is frequently lower than 30. In this case, a proper statistical analysis method is required to determine whether or not the normality is satisfied by performing a normality test. In this regard, this paper discusses the normality check, several methods of normality test, and several statistical analysis methods with or without normality checks.

Nanophthalmos is a rare disease that results from arrested development of the globe after closure of the embryonic fissure and is characterized by a small eye with thickened sclera, uveal effusion, non-rhegmatogenous retinal detachment and narrow angle glaucoma. Treatments include medical, laser and surgical theraphy for glaucoma, and surgical treatments like scleral resection, anterior sclerotomy and vortex vein decompression surgery for the drainage of the uveal effusion, etc. We experienced a case of nanophthalmos with narrow angle glaucoma and choroidal effusion in 34 year-old male patients. Anterior sclerotomy for the drainage of the uveal effusion was performed and the scleral tissue obtained. Histopathologic study on the sclera showed abnormal collagen fibers.

Objectives: . The aim of this study was to investigate whether preserved vestibular function in the high-frequency range influences the prognosis of patients with bilateral vestibulopathy (BVP) after vestibular rehabilitation. Methods: . Twenty-four patients followed up with vestibular rehabilitation were recruited. The enrolled patients were divided into two groups according to the preservation of the high-frequency vestibulo-ocular reflex (VOR) based on the video head impulse test (vHIT). The results of computerized dynamic posturography and the Dizziness Handicap Inventory (DHI) survey collected at baseline and at the 6-month follow-up after vestibular rehabilitation therapy were analyzed. Results: . Both groups showed significantly increased composite and DHI scores after follow-up with vestibular rehabilitation. The group with preserved high-frequency VOR showed a better composite score (p=0.064) and vestibular score (p= 0.008) than the group with lost high-frequency VOR at the 6-month follow up. The DHI score significantly decreased only in the group with lost high-frequency VOR (p=0.047). Among the three vestibular function tests (caloric test, rotary chair test, and vHIT) used to diagnose BVP, only vHIT showed a significant correlation (p=0.015) with a favorable prognosis (composite score ≥70). Conclusion . Better treatment outcomes are likely in patients with BVP with preserved vestibular function in response to high-frequency stimulation, as measured by the vHIT.

Acute facial nerve palsy, particularly Bell’s palsy, is a common neurological disorder with an annual incidence of 20-30 cases per 100,000 individuals. It is characterized by sudden or gradual facial muscle palsy and is caused by viral reactivation, inflammation, or ischemia of the facial nerve. Prognosis varies widely, depending on the severity of nerve damage and timeliness of the intervention. Steroid therapy remains the cornerstone of Bell’s palsy treatment because it reduces inflammation and facilitates recovery. Early administration, preferably within 72 hours of symptom onset, considerably improves outcomes. However, the efficacy of combination therapy remains controversial. Current guidelines recommend oral steroids as the primary treatment for Bell’s palsy and suggest the selective use of antiviral agents in severe cases or when viral involvement is strongly suspected. For severe facial palsy, such as Ramsay Hunt syndrome or varicella-zoster virus-induced cases, combination therapy may improve outcomes and reduce sequelae; however, high-quality evidence is limited. Steroid therapy is the main treatment of Bell’s palsy and antiviral therapy can be added in severe cases to improve prognosis. Additional research is required to develop standardized guidelines, concerning the use of antiviral therapies in conjunction with steroids.

PURPOSE: To evaluate the clinical relationship between medial collateral ligament(MCL) complete detachment and mechanical alignment in total knee arthroplasty. MATERIALS AND METHODS: From February 2001 to December 2006, we performed 290 TKAs. 9 TKAs(0.03%) happened MCL complete detachment. 1 TKA was excluded for paraplegia. All cases were women. The mean age was 71.1 years old. The mean follow-up period was 41.1 months. There were 7 degenerative osteoarthritis and 1 rheumatoid arthritis. The clinical evaluation included Knee Society Score(KSS), function score and range of motion(ROM) at preoperative, postoperative 3 months, 6 months, 12 months and final follow-up. We measured the femoro-tibial angle and the mecha- nical axis by anterior-posterior and whole lower extremity radiograph. The medial instability obtained serial valgus stress radiograph. RESULTS: There were 4 neutral and 4 varus alignment. KSS, function score, ROM was significantly improved in both group, and there were no significant differences in both group. On serial valgus stress radiograph, the difference compared with normal side decreased from 5.2 degree(postoperative 3 months) to 3.4 degree(final follow-up) in neutral alignment group, from 2.9 degree to 0.9 degree in varus alignment group. In final follow-up, it revealed that the medial instability of varus alignment group was less than that of neutral alignment group. CONCLUSION: In MCL complete detachment, some stability obtained by repair of medial collateral ligament and bracing. Whole instability was not gone. Therefore, we should make the varus alignment of prosthesis in mechanical axis line position of 34 to 67% on the medial tibial plateau.
