Pseudomeningocele after spine surgery can cause various symptoms, but it can also be silent. We experienced 3 cases of pseudomeningocele with different symptoms and we analyzed the characteristics of each case. A small pseudomeningocele without connection to the subarachnoidal space can show no symptoms. A pseudomeningocele with a small dural tear and it's abutted on the duramater at a small portion can produce sciatica and limitations of straight leg raising due to adhesion of the cauda equina around the dural tear. In addition, a large pseudomeningocele with a big dural and lamina defect can produce back tenderness furthermore, a patient with such a lesion can have low back pain and leg pain that are aggravated by an increment of abdominal pressure or by impact to the body and even by walking. Pseudomeningocele should be suspected when symptoms recur after spine surgery and especially in the case of dural tear during an operation

We performed a primary vitrectimy using scleral depression technique for uncomplicated rhegmetogenous retinal detachment and intended to highlight the importance of scleral depression technique. The indications for the primary vitrectomy were eyes with multiple or posteriorly located retinal breaks, unidentified retinal breaks, vitreous opacities, strong vitreous tractions on the retina tear flap, and aphakic/pseudophakic retinal detachments, Removal of vitreoretinal traction and vitreous base dissection using scleral depression technuque were performed in sixty-eight eyes of rhegmatogenous retinal detachment uncomplicated with proliferative vitreoretinopathy of grade C or worse. Scleral segmental buckle or encircling was also placed in 60 of 68 eyes. The retina was reattached after the primary operation in fifty-seven eyes(80.9%), and after reoperations in remaining eleven eyes(19.1%). Postoperative visual acuity was 0.4 or better in thirty-eight eyes (55.9%), and worse than 0.025 in eight eyes(11.8%). Vitrectomy in conjuction with scleral depression technique would be effective in increasing surgical success rate in selected cases of retinal detachment surgery.

Osler-Weber-Rendu disease is a rare autosomal dominant disorder of fibrovascular tissues, characterized by a classic triad of mucocutaneous telangiectasias, recurrent hemorrhages, and a familial occurrence. Portosystemic encephalopathy in a patient with Osler-Weber-Rendu disease is rare, but we experienced a case presenting with recurrent portosystemic encephalopathy in Osler-Weber-Rendu disease. We report on a case of a 75-year-old female presenting with an altered mentality. Initial studies including brain imaging study did not reveal any specific cause for her mental status. She was diagnosed with the rare disease after a series of tests and received conservative treatment. Her neurological status recovered fully without complication after conservative treatment and she was discharged after 18 hospital days. This case demonstrated an extremely rare case of Osler-Weber-Rendu disease presenting as portosystemic encephalopathy treated successfully with conservative treatment. For patients who have shown hepatic encephalopathy without a definite cause, we recommend evaluation for the possibility of Osler-Weber-Rendu disease. Conservative treatment based on treatment of advanced liver cirrhosis could be an alternative solution.

Ischemic colitis is generally considered a disease of the elderly. The causes of ischemic colitis include low-flow states due to cardiac dysfunction or hypovolemia and certain medications including estrogen. Here we report a case of ischemic colitis in a 26-year-old woman. She had no specific medical history except taking oral-contraceptives for a long time. The mechanism of estrogen-induced ischemic colitis is not clearly understood. But we recommend that oral-contraceptives should be considered as a cause of ischemic colitis in young women.

Eosinophilic esophagitis (EoE) is a disorder characterized by isolated eosinophilic infiltration of the esophagus with esophageal symptoms. Although some patients with EoE are related to food hypersensitivity, it is hard to identify causative foods. This report describes a case of EoE with dysphagia. A 28-year-old man presented with dysphagia and substernal discomfort for 15 days. He had taken a protein complex for 2 months. Endoscopy showed several linear furrows and multiple mucosal nodularities on the lower and mid esophagus, and the biopsies of esophagus revealed marked eosinophil infiltration in the mucosa. The skin testing for the protein complex was positive. The patient was successfully treated with withholding treatment.

BACKGROUND: Although rheumatic mitral stenosis is still a prevalent and clinically significant valvular heart disease in Korea, the natural history of rheumatic mitral stenosis has not been clearly determined yet. The present study aimed to evaluate the clinical and echocardiographic changes in patients with rheumatic mitral stenosis according to different therapeutic modalities. METHODS: A total of 91 patients (66 women; mean age, 50.9+/-12 years) with dominant rheumatic mitral stenosis and mitral valve area of less than 1.5 cm2 who were followed for more than 3 years (mean: 5.1 years) were included in this study. The subjects were divided into 3 groups according to the therapeutic modalities for mitral stenosis (A: medical therapy (n=31), B: percutaneous mitral valvuloplasty (n=30), C: mitral valve replacement (n=30)). Clinical and echocardiographic follow-up was performed before and immediately after therapeutic intervention such as percutaneous mitral valvuloplasty (PMV) and mitral valve replacement (MVR) and every year thereafter. Clinical symptoms and echocardiographic findings were compared between 3 groups. RESULTS: The patients of group B consisted of less females and more younger (p=NS). Clinical symptom of dyspnea was more severe in group B and C initially (A: 1.8+/-0.8, B: 2.5+/-0.8, C: 2.9+/-0.7; A vs. B, A vs. C, p<0.05) but more improved in group B and C (A: 1.6+/-0.5, B: 1.3+/-1.0, C: 1.6+/-0.5; A vs B, A vs. C, p<0.05) during the follow-up. The prevalence of atrial fibrillation did not change significantly during follow-up. Mitral valve area decreased significantly in A group from 1.1+/-0.4 to 0.9+/-0.3 cm2 (p<0.05), but, no significant change was observed in group B and C. No significant changes were observed in the left ventricular end-diastolic, end-systolic dimensions, and ejection fraction during the follow-up period. No clinically significant aggravations of associated valvular regurgitations and systolic pulmonary artery pressure were observed. CONCLUSION: In patients with mitral stenosis more than moderate severity, PMV or MVR is superior to medical therapy for controlling clinical symptoms and maintaining the mitral valve area. Therapeutic modality does not influence the change in the dimension and systolic function of the left ventricle. Accompanied other valvular regurgitation does not change significantly regardless of therapeutic modality, indicating that any additional therapy for associated valvular regurgitation is unnecessary.

BACKGROUND/AIMS: Recently, the incidence of acute hepatitis A has increased nationwide and is related to the low rate of IgG anti-HAV. This study compared the prevalence of IgG anti-HAV in two university hospitals located in a large city and in a small city including a rural region according to age, gender, and the year of diagnosis. METHODS: IgG anti-HAV was measured in a total of 4299 patients, who visited Seoul or Guri Hanyang University Hospital between January 2002 and December 2006. RESULTS: The positive rates of the antibody in Seoul and Guri hospitals were 52.7% vs 57.1% in under the age of 1, 40.7% vs 42.2% in age of 1 to 4, 31.8% vs 30.3% in age of 5 to 9, 24.8% vs 27.1% in age of 10 to 14, 11.6% vs 18.2% in age of 15 to 19, 23.0% vs 20.3% in age of 20 to 24, 40.5% vs 42.9% in age of 25 to 29, 67.5% vs 75.0% in age of 30 to 34, 86.5% vs 88.1% in age of 35 to 39, 95.3% vs 93.6% in age of 40 to 44, 97.0% vs 98.7% in age of 45 to 49, and 98.5% vs 98.6% in patients who were more than 50, respectively. The positive rates of the antibody were not significantly different between two sites according to each age group and gender. CONCLUSIONS: The results confirmed the low rates of IgG anti-HAV, particularly in the ages of 10-24 that match the age group of recently increased incidence of acute hepatitis A nationwide. Therefore, measurement of the antibody and vaccination should be considered in this age group.

Hemorrhage in the gallbladder (GB) is usually associated with cholecystitis, GB neoplasm, trauma, hemobilia, and cystic artery aneurysm. Our patient had not experienced any previous abdominal trauma, and GB hemorrhage was unlikely to result from cholecystitis or bleeding diathesis. A 55-year-old male was admitted because of right upper quadrant pain. Both prothrombin time and partial thromboplastin time were normal. Abdominal computed tomography, endoscopic ultrasound and magnetic resonance cholangiopancreatography were performed. Image studies revealed GB wall thickening and an intraluminal mass. Laparoscopic cholecystectomy was performed. Upon opening the GB postoperatively, a large amount of fresh blood and old blood clot was noted. The incidence of GB hematoma is very rare. GB hematoma should always be considered in the differential diagnosis of GB tumor. In such a situation, surgical intervention is needed for further patient evaluation and management. We present a rare case of intramural GB hematoma, of which we were unable to make a definitive diagnosis preoperatively.
