18p deletion syndrome is a rare disorder which is accompanied with mental retardation, facial
abnormalities and short stature. Dystonic findings are rarely seen and only 12 cases have been reported
in the literature until now. We report here a 26 year old female complaining of spasms on her trunk
and limb muscles. Genetic investigation revealed 18p deletion.

Femoral mononeuropathy (FMN) as an extraarticular finding of rheumatoid arthritis (RA) is a phenomenon which has not been reported previously. We report a 53-year-old female patient with RA, presenting FMN findings during the course of the disease. On examination, right quadriceps and iliopsoas muscles showed grade 3 weakness on the Medical Research Council (MRC) scale. Sensory examination revealed sensory loss in the right medial leg and thigh. Patellar tendon reflex was absent in the right side. A diagnosis of a partial right femoral neuropathy was confirmed using nerve conduction study and electromyography. The probable mechanism of FMN was thought to be vasculitis.

Fibromyalgia Syndrome (FS) is a common disease characterized by diffuse, widespread pain and multiple tender points. The syndrome has been subclassified as primary (PFS) and secondary (SFS) fibromyalgia. The aim of this study was to evaluate the role of common tendinitis (rotator cuff tendinitis, bicipital tendinitis, lateral epicondylitis, De-Quervain's tendinitis and pes anserinus tendinitis) in FS. Twenty female patients with PFS, 20 with SFS and 20 female controls, matched by age and body mass index, participated in the study. Existence of common tendinitis was evaluated with specific examination methods. Right and left rotator cuff tendinitis, pes anserinus tendinitis and left lateral epicondylitis were significantly more common in patients with PFS and SFS than in control subjects. As a result, considering the central hyperexcitability present in the fibromyalgia patients, concomitant pathologies such as tendinitis which lead to shoulder, arm, and leg pain must be evaluated. Follow up and therapy for the disease must be planned according to these factors which are not only probable symptoms of FS, but also leading causes for the occurence and continuity of the pain in this disease.

PURPOSE: To evaluate the long-term outcomes of artificial urinary sphincter (AUS) implantation and to report the complication rates, including mechanical failure, erosion, and infection. MATERIALS AND METHODS: From June 1990 to May 2011, AUS (AMS 800) implantations were performed in 56 adult males by one surgeon. Various demographic and preoperative variables, surgical variables, and postoperative outcomes, including success and complication rates with a median follow-up of 96 months, were recorded retrospectively. RESULTS: The mean age of the patients at the time of AUS implantation was 61.8 (+/-14.2) years. During the follow-up period, the total complication rate was 41.1% (23 patients). The incidence of complications was significantly lower during the follow-up period after 48 months (p<0.05). Kaplan-Meier analysis revealed that 5- and 10-year failure-free rates were 50.3% and 45.2%, respectively. CONCLUSIONS: Long-term durability and functional outcomes are achievable for the AMS 800, but there are appreciable complication rates for erosion, mechanical failure, and infection of up to 30%.

Clinics in Orthopedic Surgery 2021;13(1):67-70
Background:
As mobile technology has evolved, smartphone applications have been used for radiographic angle measurements in daily clinical practice. This study aimed to assess the reliability of 2 smartphone applications (iPinPoint and Cobbmeter) in measuring scoliosis Cobb angles compared with picture archiving and communication system (PACS) tools.
Methods:
Anteroposterior whole spinal digital radiographs of 50 patients were retrospectively analyzed. Four observers measured Cobb angles of predetermined major structural curves using the tools in the PACS software and 2 smartphone applications. The inter- and intraobserver reliabilty were measured using intraclass correlation coefficients (ICC).
Results:
Very good interobserver agreement was seen with PACS, iPinPoint, and Cobbmeter measurements (ICC, 0.991, 0.980, and 0.991, respectively). Intraobserver reliability of the 4 observers was also very good for all techniques (ICC > 0.9 for all observers).
Conclusions
Both smartphone applications were reliable in measuring scoliosis Cobb angles, with reference to PACS tools. They may be useful when digital or manual mesurement tools are not available.

BACKGROUND/AIMS: Chronic arthritis of familial Mediterranean fever (FMF) involves weight-bearing joints and can occur in patients without a history of acute attack. Our aim was to investigate a possible causal relationship between FMF and osteoarthritis in a population in which FMF is quite common. METHODS: Patients with late stage primary osteoarthritis were enrolled, and five MEFV gene mutations were investigated. The frequency of MEFV gene mutations was compared among patients with osteoarthritis and a previous healthy group from our center. RESULTS: One hundred patients with primary osteoarthritis and 100 healthy controls were studied. The frequency of MEFV gene mutations was significantly lower in the osteoarthritis group (9% vs. 19%). M694V was the most frequent mutation (5%) in the osteoarthritis group, whereas in the control group, E148Q was the most common (16%). In subgroup analyses, the mutation frequency of patients with hip osteoarthritis was not different from that of patients with knee osteoarthritis and controls (7.1%, 9.7%, and 19%, respectively). There were no differences among the three groups with respect to MEFV gene mutations other than E148Q (8.1% vs. 3.6%). E148Q was significantly lower in the osteoarthritis group than in the controls (16% vs. 1%), although the mutations did not differ between patients with knee osteoarthritis and controls. CONCLUSIONS: In a population with a high prevalence of MEFV gene mutations, we did not find an increased mutation rate in patients with primary osteoarthritis. Furthermore, we found that some mutations were significantly less frequent in patients with osteoarthritis. Although the number of patients studied was insufficient to claim that E148Q gene mutation protects against osteoarthritis, the potential of this gene merits further investigation.

Objective: It is aimed to present our experience in carotid artery stenting with attention to the patient
selection, technique, success rate, perioperative complications, and efficacy. Methods: Patients presented
with carotid stenosis treated by stenting were included. Symptomatic patients were defined as having
a history of transient ischemic attack or stroke in the last 6 months. Patients with symptomatic
carotid stenosis of at least 50% or asymptomatic carotid stenosis of at least 70% detected by catheter
angiography were accepted for treatment. Distal embolic protection devices were used in all patients.
Technical success was defined as the luminal patency at least 70%. Results: The study consisted of
94 patients with 98 procedures and the mean age was 66.38±11.13 years. The mean stenosis rate was 74.52±13.44%. A total of 109 stents were used in 97 procedures, and closed-cell design was used in 87.2% versus open-cell design in 12.8%. Technical success and complication rate were 98.9% and
8.2%, respectively. The mean follow-up period was 14.92±10.76 months.
Conclusion: Carotid artery stenting with use of distal embolic protection devices is widely accepted,
safe, feasible, less invasive when compared to surgery and can be performed successfully especially
in patients with high risk factors.
