Objective: To investigate the clinical characteristics of systemic juvenile idiopathic arthritis combined with coronary artery dilatation. Methods: A retrospective analysis was performed on the clinical data, including clinical manifestations, blood routine, inflammatory factors, echocardiography, vascular ultrasound and CT angiography, treatment and outcomes, etc, of 5 cases with systemic juvenile idiopathic arthritis combined with coronary artery dilation admitted to Department of Rheumatology in the affiliated Children's Hospital of Capital Institute of Pediatrics from May 2019 to June 2021. Results: There were 2 males and 3 females among 5 cases. The onset age ranged from 7 months to 4 years 7 months.The diagnostic time ranged from 1.5 months to 3.0 months.Four cases were diagnosed as atypical Kawasaki disease. Three cases showed unilateral coronary artery dilation.Two cases showed bilateral coronary artery dilation.Four cases developed multiple organ injuries.Three cases developed macrophage activation syndrome.Three cases developed lung injury.Two cases developed pericardial effusion.One case developed pulmonary hypertension.As for treatment, 3 cases treated with methylprednisolone pulse therapy and methotrexate combined with cyclosporine, improved after the final application of biological agents, and have stopped prednisone. The other 2 cases were treated with adequate oral prednisone and gradually reduced, and methotrexate was added at the same time, 1 case relapsed in the process of reduction. No other vascular involvement was found in 5 cases. Coronary artery dilation recovered completely after 1 to 3 months of treatment. Conclusions: Systemic juvenile idiopathic arthritis combined with coronary artery dilatation has the clinical characteristics of small onset age, long diagnostic time, prone to multiple organ injuries. Corticosteroids and conventional immunosuppressive agents are not sensitive, and biological agents should be used as soon as possible.The prognosis of coronary artery dilation is good after timely treatment.

OBJECTIVETo evaluate the effect of meatoplasty with the pedicle flap in the treatment of meatal stenosis secondary to chronic balanitis.

METHODSWe retrospectively analyzed 32 cases of meatal stenosis secondary to chronic balanitis treated by meato- plasty with the pedicle flap. All the patients had a history of chronic balanitis and had received meatal dilatation or simple ventral mea- totomy without significant effect. Their mean maximum urinary flow rate (Qmax) was (4.3 ± 2.4) ml/s. During the operation, A "/\"-shaped incision was made in the healthy epidermis and a flap was harvested from the frenulum. After complete removal of the scar, the flap was placed into the urethral wall, followed by reconstruction of the external urethral orifice.

RESULTSThe patients were fol- lowed up for 6 to 30 months, which revealed smooth urination in all the patients with Qmax of (26.7 ± 4.5) ml/s and normal erectile function and uresiesthesis.

CONCLUSIONWith little invasiveness and few complications, meatoplasty with the pedicle flap is an ideal surgical method for the treatment of meatal stenosis secondary to chronic balanitis. However, there might be some change in the normal appearance of the balanus postoperatively, and its long-term effect needs further observation.

BACKGROUND/AIMS: The aim of this study was to evaluate the outcome of endoscopic dilation for benign anastomotic stricture after radical gastrectomy in gastric cancer patients. METHODS: Gastric cancer patients who underwent endoscopic balloon dilation for benign anastomosis stricture after radical gastrectomy during a 6-year period were reviewed retrospectively. RESULTS: Twenty-one patients developed benign strictures at the site of anastomosis. The majority of strictures occurred within 1 year after surgery (95.2%). The median duration to stenosis after surgery was 1.70 months (range, 0.17 to 23.97 months). The success rate of the first endoscopic dilation was 61.9%. Between the restenosis group (n=8) and the no restenosis group (n=13), there were no significant differences in the body mass index (22.82 kg/m2 vs 22.46 kg/m2), interval to symptom onset (73.9 days vs 109.3 days), interval to treatment (84.6 days vs 115.6 days), maximal balloon diameter (14.12 mm vs 15.62 mm), number of balloon dilation sessions (1.75 vs 1.31), location of gastric cancer or type of surgery. One patient required surgery because of stricture refractory to repeated dilation. CONCLUSIONS: Endoscopic dilation is a highly effective treatment for benign anastomotic strictures after radical gastrectomy for gastric cancer and should be considered a primary intervention prior to proceeding with surgical revision.

Extrinsic compression of the left main coronary artery (LMCA) secondary to pulmonary artery dilatation is a rare syndrome. Most cases of pulmonary artery hypertension but no atherosclerotic risk factors rarely undergo coronary angiography, and hence, diagnoses are seldom made and proper management is often delayed in these patients. We describe a patient that presented with pulmonary hypertension, clinical angina, and extrinsic compression of the LMCA by the pulmonary artery, who was treated successfully by percutaneous coronary intervention. Follow-up coronary angiography showed patent stent in the LMCA in the proximity of the dilated main pulmonary artery. This case reminds us that coronary angiography and percutaneous coronary intervention should be considered in pulmonary hypertension patients presenting with angina or left ventricular dysfunction.

Self-expandable stents are widely available for the treatment of perforation of the gastrointestinal tract. Because of the risk of migration, there has been no report of the use of self-expandable stents for the treatment of perforation of the colon or rectum. This is a report of successful treatment of iatrogenic colonic perforation during balloon dilatation of anastomotic stricture with a fully covered stent. Fully covered, self-expandable metallic stents can be considered useful tools for management of this condition.

We describe a unique case of a patient who presented with a linear, transverse, and incidentally-detected main pancreatic duct dilatation that was caused by the intrapancreatic-replaced common hepatic artery, detected on the MDCT, MRCP and endoscopic retrograde cholangiopancreatography. We believe this case to be the first of its kind reported in the literature.

Although pulsatile tinnitus can be audible, objective demonstration of this heartbeat-synchronous sound has rarely been successful. We report a rare case of pulsatile tinnitus in a 44-yr-old female patient, which was induced by a large mastoid emissary vein (MEV) and objectively documented by Doppler sonography of the left posterior auricular region. The tinnitus was intermittent and the patient could adapt to the tinnitus without intervention on the mastoid emissary vein. These findings suggest that a single large MEV can cause pulsatile tinnitus in the absence of other vascular abnormalities, and imaging studies of the posterior fossa and Doppler ultrasonography can aid the diagnosis in such cases.

The Ross operation, a procedure of replacement of the diseased aortic valve with an autologous pulmonary valve, has many advantages such as no need for anticoagulation therapy and similar valve function and growth potential as native valves. However secondary aortic disease has emerged as a significant complication and indication for reoperation. We report a 48-year-old woman who had Ross operation in 1997 for a damaged bicuspid aortic valve and severe aortic regurgitation due to subacute bacterial endocarditis complicated by aortic root abscess. In 2009, 12 years later, progressive severe aortic regurgitation with incomplete coaptation and mild dilatation of the aortic root was shown on echocardiography and contrasted CT, while the pulmonary homograft retained normal function. She subsequently underwent aortic valve replacement. Histopathological examination of the explanted neo-aortic valve and neo-arterial wall revealed pannus formation at the nodulus Arantii area of the three valve cusps, ventricularis, and arterialis. The amount of elastic fibres in the neo-aorta media was less than usual for an aorta of this patient's age but was similar to a pulmonary artery. The pathological findings were not different from other studies of specimens removed between 7 to 12 years after Ross operation. However, the pathophysiology and long-term implications of these findings remain debatable. Considering the anatomical and physiological changes induced by the procedure, separate mechanisms for aortic dilatation and regurgitation are worthy of consideration.

OBJECTIVETo compare the findings of pancreaticobiliary duct dilation due to pancreatic carcinoma and chronic pancreatitis by magnetic resonance cholangiopancreatography (MRCP).

METHODSMRCP findings in 28 cases of pancreatic carcinoma and 42 cases of chronic pancreatitis were retrospectively analyzed. Both plain MR and MRCP examinations were performed in all the cases after oral Gd-DTPA dilution.

RESULTSMRCP in the patients with pancreatic carcinoma displayed dilated pancreatic duct with smooth and regular caliber (n=16, 72.7%), dilated common biliary duct with abrupt rupture in most cases (n=18, 90%) and intra- and extra-hepatic cholangiectasis (n=12, 42.8%), and the double-duct sign (n=19, 86.5%). In the patients with chronic pancreatitis, MRCP identified irregular dilation of the pancreatic duct across the whole segment of the lesion (n= 20, 60.6%), taper of the dilated common bile duct (n=8, 80%), stones within the pancreatic duct (n=5, 11.9%), and pancreatic pseudocsyt within the pancreatic duct (n=21, 50%).

CONCLUSIONCholangiopancreatographic findings of pancreaticobiliary duct dilation are of great value in distinguishing pancreatic carcinoma from chronic pancreatitis.
