Painful periarticular calcification most commonly occurs within the rotator cuff of the shoulder and rarely around the elbow, hip, foot, and neck. As acute inflammatory reaction develops, severe pain, exquisite tenderness, local swelling, and limitation of motion with pain occur. In case of calcific tendinitis of the shoulder, it can be easily diagnosed according to the symptoms and with x-ray. However, in lesions of the hip, as it is a rare location and usually involves pain in the posterolateral aspect of the thigh, which can simulate radicular pain from a lumbar intervertebral disc, it could be difficult to diagnose. Hence, physicians usually focus on lumbar lesions; therefore, misdiagnosis is common and leads to a delayed management. Here, we report the case of a 30-year-old female patient with calcific tendinitis of the rectus femoris that was successfully managed with ultrasound-guided steroid injection. This study offers knowledge about the rectus femoris calcification.

During the past three decades the treatment in rheumatology was revolutionized by the introduction of disease-modifying anti-rheumatic drugs. Advances in our understanding of the pathogenesis of rheumatic diseases have led to the discovery of critical pathogenetic mechanisms of inflammation and autoimmunity and the invention of new target-specific biologic agents. The development of biologic agents led to a new era in treatment of various rheumatic diseases. Treatments of rheumatic diseases such as rheumatoid arthritis (RA) had been very difficult in former days until conventional DMARDs was developed. Although synthetic DMARDs made it a lot easier to control rheumatic diseases, still, there were some difficulties on controlling diseases. The biologic agents inhibit specific pro-inflammatory cytokines as a targeted therapy to prevent inflammation and destruction of affected joint and/or tissues. Three TNF blocking agents, etanercept, infliximab and adalimumab, are the most well recognized and widely used biologic agents in RA, ankylosing spondylitis (AS), and some other inflammatory autoimmune diseases. Furthermore, an inhibitor of IL-1 (anakinra), a B-cell depleting drug (rituximab) and an inhibitor of T-cell costimulation (abatacept) are developed in turn asnovel biologic agents which are believed to be effective in number of rheumatic diseases. Recently, an inhibitor of IL-6 (tocilizumab) and 2 other TNF inhibitors (golimumab and certolizumab) are developed. Here, the brief descriptions of recently used biologic agents and their efficacies and safeties are discussed.

PURPOSE: To compare the lesion conspicuity of radiofrequency ablation (RFA) zones among MR sequences according to time in the normal rabbit liver. MATERIALS AND METHODS: RFA zones were created in 12 rabbit livers with a 17-gauge internally cooled electrode (1-cm active tip, 30 Watts, 3 minutes). Three rabbits were sacrificed immediately, three days, two weeks, and six weeks after the RFA procedure, respectively. Before sacrifice, T1-, T2-weighted images (WI), and gadolinium-enhanced (GE)-T1WI images were obtained. The lesion conspicuity of the RFA zone and the contrast-to-noise ratio (CNR) of the RFA zone to the liver parenchyma were analyzed and compared among the MR sequences according to time. RESULTS: On T1WI, the RFA zones were only clearly seen on acute phase. On T2WI, the RFA zones were clearly seen on all phases except the hyperacute phase. On GE T1WI, the RFA zones were clearly seen on all phases. The CNRs of the RFA zone to the liver parenchyma of GE-T1WI (8.1-12.4) were significantly higher than the CNRs of TIWI (1.6-2.7) and T2WI (1.7-6.3) on all phases (p < 0.05), but the visual lesion conspicuity between GE T1WI and T2WI were similar. CONCLUSION: On hyperacute phase, GE T1WI showed better lesion conspicuity of the RFA zone than T1WI and T2WI. On other phases, GE T1WI and T2WI showed similar lesion conspicuity.

There are various origins for chronic abdominal pain. About 10-30% of patients with chronic abdominal pain have abdominal wall pain. Unfortunately, abdominal wall pain is not thought to be the first origin of chronic abdominal pain; therefore, patients usually undergo extensive examinations, including diagnostic laparoscopic surgery. Entrapment of abdominal cutaneous nerves at the muscular foramen of the rectus abdominis is a rare cause of abdominal wall pain. If abdominal wall pain is considered in earlier stage of chronic abdominal pain, unnecessary invasive procedures are not required and patients will reach symptom free condition as soon as the diagnosis is made. Here, we report a case of successful treatment of a patient with abdominal cutaneous nerve entrapment syndrome by ultrasound guided injection therapy.

The diagnosis and appropriate management of blunt abdominal trauma including retroperitoneal hematoma associated head injury is difficult. In our case, psoas muscle hematoma was revealed during the evaluation of fever. Psoas muscle hematoma most commonly results secondarily from coagulation defect or from retroperitoneal bleeding into the psoas sheath. The presenting signs and symptoms of this case are hypotension and anemia. Pain is also present in the back or abdomen. If it is associated with head injury and not presented massive hemorrhage, the actual diagnosis is not easy. The appropriate management depends on a careful initial evaluation including suspicion of physician, repetitive physical examination, the timely use of diagnostic procedures.

The effects of statins on insulin resistance and new-onset diabetes are unclear. The purpose of this study was to evaluate the effects of rosuvastatin on insulin resistance and adiponectin in patients with mild to moderate hypertension. In a randomized, prospective, single-blind study, 53 hypertensive patients were randomly assigned to the control group (n=26) or the rosuvastatin (20 mg once daily) group (n=27) during an 8-week treatment period. Both groups showed significant improvements in systolic blood pressure and flow-mediated dilation (FMD) after 8 weeks of treatment. Rosuvastatin treatment improved total cholesterol, low-density lipoprotein (LDL)-cholesterol, and triglyceride levels. The control and rosuvastatin treatment groups did not differ significantly in the change in HbA1c (3.0+/-10.1% vs. -1.3+/-12.7%; p=0.33), fasting glucose (-1.3+/-18.0% vs. 2.5+/-24.1%; p=0.69), or fasting insulin levels (5.2+/-70.5% vs. 22.6+/-133.2%; p=0.27) from baseline. Furthermore, the control and rosuvastatin treatment groups did not differ significantly in the change in the QUICKI insulin sensitivity index (mean change, 2.2+/-11.6% vs. 3.6+/-11.9%; p=0.64) or the HOMA index (11.6+/-94.9% vs. 32.4+/-176.7%; p=0.44). The plasma adiponectin level increased significantly in the rosuvastatin treatment group (p=0.046), but did not differ significantly from that in the control group (mean change, 23.2+/-28.4% vs. 23.1+/-27.6%; p=0.36). Eight weeks of rosuvastatin (20 mg) therapy resulted in no significant improvement or deterioration in fasting glucose levels, insulin resistance, or adiponectin levels in patients with mild to moderate hypertension.

PURPOSE: Patients often complain of change of defecation pattern and it is necessary to quantify their symptoms. To quantify symptoms, use of questionnaire is ideal, so we adopted a simple and easily writable visual analogue scale for irritable bowel syndrome questionnaire (VAS-IBS). The aim of this study was to develop and validate the Korean version of VAS-IBS questionnaire (Korean VAS-IBS) that can adequately reflect the defecation pattern. METHODS: This study translated English VAS-IBS into Korean using the forward-and-back translation method. Korean VAS-IBS was performed on 30 patients, who visited the outpatient clinic and had no possibility of special defecation pattern. Detailed past medical history and Bristol stool chart was added to the questionnaire. The survey was conducted twice, and the median interval between the 2 surveys was 10 days (8–11 days). Cronbach α for internal consistency reliability and intraclass correlation coefficients for test-retest reliability were analyzed. RESULTS: Korean VAS-IBS achieved acceptable homogeneity with a Cronbach α coefficient of 0.66–0.79 showing adequate internal consistency reliability. In addition, intraclass correlation coefficients showed significant test-retest reliability with 0.46–0.80 except for the question assessing the “perception of psychological wellbeing.” CONCLUSION: The Korean VAS-IBS is a valid and reliable questionnaire for the measurement of the symptoms of defecation pattern changes.

OBJECTIVE: Recently, the atypical antipsychotics such as quetiapine, olanzapine, risperidone, aripiprazole and ziprasidone are increasingly used in the management of acute manic patients as the monotherapy. But there are only a few reports on the use of these drugs in the treatment of bipolar disorder in Korea. The aim of this study was to evaluate the efficacy and tolerability of quetiapine monotherapy in patients with acute mania. METHOD: This study is multi-center, open-label, 6-week evaluation of the efficacy of quetiapine in bipolar mania. In this study, patients with a DSM-IV diagnosis of bipolar I disorder (manic or mixed episodes) were included to treatment with quetiapine (flexibly dosed up to 800 mg/day). Clinical improvements were rated by Young Mania Rating Scale (YMRS), Clinical Global Impression-Bipolar Version (CGI-BP), Brief Psychiatric Rating Scale (BPRS) and Montgomery-Asberg Depression Rating Scale (MADRS). Adverse events were measured using Simpson-Angus Rating Scale (SARS) and Barnes Akathisia Rating Scale (BARS), and subjective reports of patients were evaluated. Global Assessment Scale (GAS) was used to evaluate the general functioning of patients. All assessments were done at baseline and at days 7, 14, 21, and 42 except GAS (at days 21 and 42). Analyses were focused on change from baseline to day 42. RESULTS: Total 78 (male=30, female=48) patients were included and 59 patients (75.6%) completed the study. The mean initial dose of quetiapine was 268.0+/-223.2 mg/day and mean daily dose at day 42 was 585.3+/-244.5 mg/day. YMRS and CGI-BP were significantly improved at day 7, 14, 21, and 42 as compared to baseline. Mean scores of BPRS and MADRS were also significantly decreased at the each assessment points. Fifty-two patients (66.7%) showed response (more than 50% of decrease in YMRS score from baseline) and 35 patients (44.6%) reached remission (YMRS score < or =12) at day 21. GAS showed the improvements of patient's global functioning at days 21 and 42 of quetiapine monotherapy compared to baseline. There was no significant difference between baseline and any assessment points on SARS and BARS scores. CONCLUSIONS: The data showed that quetiapine monotherapy has favorable effects across a broad range of mood symptoms with minimal adverse events in addition to functional improvement in acute manic patients. This result suggests that quetiapine may be preferred for patients with acute mania as one of the first-line agents.
