Osteomesopyknosis is a rare sclerosing bone disorder of autosomal dominant inheritance. We report a first case of osteomesopyknosis in Korea. A 16-year old girl complained of diffuse back pain for 1 year. We performed physical examination, biochemical investigations and imaging studies. A radiograph of spine revealed rugger-jersey vertebra and sandwich vertebra. Bone specific alkaline phosphatase, osteocalcin and C-terminal telopeptides of type I collagen were normal. Only an axial skeleton involvement was shown on the whole body bone scan. This patient was diagnosed to have osteomesopyknosis. Osteomesopyknosis is characterized by normal level of bone turnover marker and an axial bone involvement. Osteomesopyknosis can be occurred in Korea and needs to be considered when patients, especially young patients, suffer from back pain and have only axial osteosclerosis.

BACKGROUND/AIMS: Percutaneous coronary intervention (PCI) is the standard method of treating ST-segment elevation myocardial infarction (STEMI). There is continuing uncertainty as to whether reducing the thrombus burden through catheter aspiration improves the arrhythmogenic structure of the myocardium in STEMI. We compared the changes in electrical instability after thrombus aspiration-assisted primary PCI using conventional primary PCI. METHODS: The study population included 170 consecutive patients with STEMI who underwent primary PCI. The patients were divided into 80 patients who underwent primary PCI only and 90 patients who underwent thrombus aspiration before PCI. The signal-averaged ECG (SAECG) was obtained 5 +/- 2 days after the intervention. RESULTS: There were no significant differences between the groups in terms of sex, age, cardiovascular risk factors, or time from the onset of symptoms to treatment. The duration of the low amplitude signals less than 40 microV (LAS40), duration of the QRS complex (QRSD), and root mean square voltage of the terminal 40 ms of the QRS complex (RMS40) did not differ between the thrombus aspiration and no thrombus aspiration groups. The incidences of QRSD > 114 ms and RMS40 < 20 microV were significantly lower in the thrombus aspiration group than the no thrombus aspiration group (19 vs. 8, p = 0.011 and 16 vs. 8, p = 0.047, respectively), while the incidence of LAS > 38 ms was significantly higher in the non-thrombus aspiration group (18 vs. 8, p = 0.018). CONCLUSIONS: Among random patients with STEMI, thrombus aspiration improved all of the parameters of SAECG, which is related to ventricular arrhythmogenesis, although the long-term clinical outcomes need to be assessed.

Gangliocytic paraganglioma is an uncommon tumor of digestive system that is usually found in the second portion of duodenum. It is generally considered benign tumor, although few reports of local recurrences and regional lymph node metastases have been made. Gangliocytic paraganglioma is characterized by its histologic pattern including ganglion cells, spindle cells and epithelioid cells. Heterotopic pancreas, also known as ectopic pancreas, is a pancreatic tissue appeared outside of its normal location lacking anatomic or vascular connection with the pancreas. In duodenum, it is a relatively unusual lesion that may be found incidentally during surgery or endoscopy. We present a case of 39-year-old woman with gangliocytic paraganglioma combined with heterotopic pancreas in the ampulla of Vater successfully treated by endoscopic resection.
