Introduction: The symptoms of Ischiogluteal Bursitis (IGB) are often nonspecific and atypical, and its diagnosis is more challenging. Moreover, it is difficult to predict cases of chronic progression or poor treatment response. Therefore, the aim of this study was to investigate the clinical course of IGB patients and identify factors that are predictive of failure of conservative treatment. Materials and Methods: Our study consisted of IGB patients diagnosed between 2010 March and 2016 December who had been followed-up for at least one year. Structured questionnaires and medical records were reviewed to analyse demographic characteristics, lifestyle patterns, blood tests, and imaging studies. We categorized the cases into two groups based on the response to conservative treatment and the need for surgical intervention. Results: The most common initial chief symptoms were buttock pains in 24 patients (37.5%). Physical examinations showed the tenderness of ischial tuberosity area in 59 (92.2%) patients, but no specific findings were confirmed in 5 patients (7.8%). 51 patients (79.7%) responded well to the conservative management, 11 patients (17.2%) needed injection, and 2 patients (3.1%) had surgical treatment performed due to continuous recurrence. There was no difference in demographic and blood lab data between the two groups. However, the incidence of inflammatory diseases (response group: 10.3% vs non-response group: 66.7%, p=0.004) was significantly different between the two groups. Conclusion: The diagnosis of IGB can be missed due to variations in clinical symptoms, and cautions should be exercised in patients with inflammatory diseases as conservative treatment is less effective in them, leading to chronic progression of IGB.

Introduction: Accurate diagnosis of undisplaced periprosthetic femoral fracture (PFF) after hip arthroplasty is crucial, as overlooked PFF may affect its treatment and prognosis. The undisplaced PFF is often difficult to distinguish from radiolucent lines of nutrient artery canal (NAC) of the femur present on post-operative radiographs. We aimed to identify the radiographic features of NAC to distinguish them from PFFs. Materials and methods: In this retrospective radiological study, a total of 242 cases in 215 patients with hip arthroplasty were analysed using pre-operative and postoperative anteroposterior (AP) and translateral (TL) radiographs. Interobserver agreement of the measurements was assessed by two independent experienced orthopaedic surgeons. The kappa value ranged from 0.83 to 0.87, indicating strong agreement according to the Landis and Koch criteria. Results: The NACs were found pre-operatively in 94 (39.8%) cases on AP views and in 122 cases (50.4%) on TL views. The radiolucent lines were observed post-operatively in 42 (17.4%) on AP views and 122 (50.4%) on the TL views. three cases (1.2%) had a fracture around the stem that were detected on radiographs. One case with PFF presented simultaneously with NAC on the immediate post-operative radiographs. All patients were treated by conservative measures, and the radiolucent lines did not appear on followup radiographs. Conclusion: It is not easy to differentiate undisplaced PFFs that can occur after hip arthroplasty operation from NACs. However, accurate diagnosis is possible through careful observation and comparison of pre-operative and postoperative radiologic images

The survey on branchial anomalies was conducted by Korean Association of Pediatric Surgeons. A total of 173 cases were reported, which were managed by 36 members and cooperators during the three years from January 1, 1993 through December 31, 1995. The following results were obtained by retrospective analysis of the 173 cases of branchial anomalies. The presenting symptoms were cervical mass in 101 cases, pit with or without discharge in 71, cervical abscess in 47 and respiratory difficulty in 3. The average age of the patients with cervical abscess was 52 months. Seventy(79%) of 89 patients with branchial anomalies and a cystic mass had their first clinical manifestations by 1 year of age, while 40(51%) of 78 patients with only a branchial cyst had their first clinical manifestation in first year of life. Radiologic studies were carried out in 77 patients(43%). The preferred diagnostic modalities were ultrasonography(47 patients), simple neck radiogram(l9) and CT scan(17). Preoperative diagnosis was correctly made in 156(91%) of 173 patients. Seventeen patients were incorrectly diagnosed as thyroglossal duct cyst in 5 patients, cystic hygroma in 4, dermoid cyst in 3, and lymphadenopathy in 3. There were no remarkable difference in sex and laterality of presentation but bilateral lesions were found in 9(5%) patients and unusual locations of the anomalies were the manubrium, left subclavicular area, median cervial area, preauricular and parotid area. There were 78(45%) patients with cyst, 52(30%) patients with sinus, 35(20%) patients with fistula and 8(5%) patient with skin tag. Embryological classification was possible in only 64(37%) patients. The 2nd branchial anomaly was present in 50 (78%), the 1st branchial anomaly in 10(18%), and the 3rd or 4th branchial anomaly in 4(6%). Histopathological study of the lining epithelium(N=134) is recorded that 45% were lined with squamous epithelium, 17% with respiratory epithelium, 6% with. squamous and respiratory epithelium, 14% with inflammatory change. Lymphoid tissue was common(62%) in the wall of the lesions. Twelve(7%) of 158 patients had postoperative complications including wound complication, recurrence and facial nerve palsy.

Focal myositis is a rare disease defined by an isolated inflammatory pseudotumour usually restricted to one skeletal muscle. Approximately, 250 cases of focal myositis have been described in the literature, and two recent large cohorts have been used to help in the diagnosis. Isolated gastrocnemius myositis, a rare immune-mediated condition, is a diagnostic entity used by internal medicine clinician in the gastrocnemius myalgia syndrome associated with Crohn’s disease (CD). However, focal myositis and isolated gastrocnemius myositis with Crohn's disease share clinical, haematological, pathological, and radiological similarities. We present a case of unilateral focal myositis of the gastrocnemius muscle in a patient with no underlying diseases, including Crohn’s disease. At clinical evaluation, we encountered a challenge in differentiating between focal myositis and the isolated gastrocnemius myositis of Crohn’s due to similarities in clinical manifestation. We attempt to clarify focal myositis and isolated gastrocnemius myositis through our case report and a review of literature.
