Acute Acalculous Cholecystitis Associated with Sunitinib Treatment for Renal Cell Carcinoma / 대한소화기학회지

A 64-year-old man was treated with sunitinib as a first-line therapy for metastatic renal cell carcinoma. He was given oral sunitinib in cycles of 50 mg once daily for 2 weeks followed by a week off. During the 5th week of treatment right upper quadrant pain developed, but this resolved spontaneously during the 6th week (off treatment). However, on the 8th week of treatment, he was admitted to hospital because the acute right upper quadrant pain recurred with nausea, vomiting, and fever. Acute acalculous cholecystitis was then diagnosed by ultrasonography and CT. In addition, his laboratory findings indicated disseminated intravascular coagulation. Accordingly, sunitinib therapy was discontinued and broad-spectrum antibiotics initiated. He subsequently recovered after emergent percutaneous cholecystostomy. His Naranjo Adverse Drug Reaction Probability Scale score was 7, indicaing a probable association of the event with sunitinib. Suspicion of sunitinib-related acute cholecystitis is required, because, although uncommon, it can be life-threatening.

Chronic Recurrent Multifocal Osteomyelitis on the Distal Tibia and Fibula / 대한정형외과학회잡지

Chronic recurrent multifocal osteomyelitis (CRMO) is a non-infectious inflammatory bone disease that occurs mainly in children and adolescents. The clinical presentation shows imprecise bone pain, while radiologic findings and histologic exam are similar to those of infectious osteomyelitis. It is a rare disease, which is difficult to distinguish from other diseases, therefore it could be misdiagnosed. We report on a case of CRMO on the distal tibia and fibula in an 11-year-old boy.

The Factors Affecting Pain Pattern after Arthroscopic Rotator Cuff Repair

BACKGROUND: We evaluated the factors that affect pain pattern after arthroscopic rotator cuff repair. METHODS: From June 2009 to October 2010, 210 patients underwent arthroscopic rotator cuff repair operations. Of them, 84 patients were enrolled as subjects of the present study. The evaluation of postoperative pain was conducted by visual analog scale (VAS) scores during postoperative outpatient interviews at 6 weeks, 3 months, 6 months, and 12 months. The factors that were thought to affect postoperative pain were evaluated by dividing into three categories: preoperative, operative, and postoperative. RESULTS: Pain after arthroscopic rotator cuff repair surgery showed a strictly decreasing pain pattern. In single analysis and multiple regression tests for factors influencing the strictly decreasing pain pattern, initial VAS and pain onset were shown to be statistically significant factors (p = 0.012, 0.012, 0.044 and 0.028, respectively). With regard to the factors influencing lower than average intensity pain pattern for each period, the stiffness of internal rotation at 3 months postoperatively was shown to be a statistically significant factor in single and multiple regression tests (p = 0.017 and p = 0.004, respectively). CONCLUSIONS: High initial VAS scores and the acute onset of pain affected the strictly decreasing postoperative pain pattern. Additionally, stiffness of internal rotation at postoperative 3 months affected the higher than average intensity pain pattern for each period after arthroscopic rotator cuff repair.

Clinical Assessment after the Volar Locking Plate Removal of Distal Radius Fracture

PURPOSE: The purpose of this study is to evaluate the clinical outcomes after removing the volar locking plate for distal radius fracture. MATERIALS AND METHODS: We reviewed retrospectively the medical records of 34 patients, 36 cases after removing the plates among 150 patients, with 162 cases that underwent open reduction and internal fixation using the volar locking plate between January 2006 and May 2011. We performed preoperative and postoperative clinical assessments using the quick-disabilities of the arm, shoulder and hand (Q-DASH), the visual analog scale (VAS) score, and the range of motion on wrist, grip and pinch power. RESULTS: The major reason for plate removal was the time to remove the plate according to the fracture union and the patient's demand without other specific complaints (28 cases). The mean preoperative VAS score was 1.78 and the mean postoperative VAS score 1.81 (p=0.64). The mean preoperative Q-DASH score was 30.02 and the mean postoperative Q-DASH score 38.46 (p<0.001). The mean preoperative grip and pinch power were 18.14 kg and 7.67 kg. The mean postoperative grip and pinch power were 15.27 kg and 6.94 kg (p=0.23). CONCLUSION: The removal of the volar locking plate for distal radius fracture should be decided by considering the patient's clinical and socioeconomic conditions carefully.

A Case of Pulmonary Arterial Hypertension Associated With Hyperthyroidism, Persistent After Euthyroidism Was Obtained

Cardiovascular manifestations in hyperthyroidism occur frequently with various phenotypes. An association between hyperthyroidism and pulmonary arterial hypertension has been reported. In previously reported cases, the hemodynamic and symptomatic recovery of pulmonary arterial hypertension is usually concomitant with achievement of euthyroidism. We report a patient who had pulmonary arterial hypertension associated with Graves' disease, which persisted after euthyroidism was obtained.
