The term, ‘crossed occlusion’ implies clinical situation in which the residual teeth in one arch have no contact with those in the antagonistic arch, resulting in the collapse of occlusal vertical dimension. The treatment goal of this pathologic condition is restoration of the collapsed vertical dimension and stabilization of abnormal mandibular position. Previously, konus removable prostheses or tooth supported overdentures were suggested to solve crossed occlusion. Nowadays, dental implants have been used for definitive support to solve this problem. In this case report, a 65 years old female patient had a crossed occlusion, in which the maxillary posterior residual teeth and mandibular anterior residual teeth cross. Interim removable and fixed dental prostheses were used to confirm the proper vertical and horizontal jaw relation. After that, the mandibular posterior edentulous region was restored with implant-supported fixed dental prostheses. Computer tomography guided implant surgery was performed according to the concept of the restoration-driven implant placement. The maxillary anterior edentulous region was restored with Kennedy class IV removable prosthesis, considering the patient’s economic status. The patient’s jaw position and prostheses have been well maintained at the follow-up after 6 months of definitive restoration. The antero-posterior crossed occlusion problems appeared to be effectively solved with the combination of removable in one arch and implant-supported fixed prostheses in the other.

Splenic abscess is a rare disease that generally occurs in immunocompromised patients. It is difficult to distinguish between splenic abscesses and cysts using imaging studies, especially if they are asymptomatic. A 50-year-old asymptomatic man who had received steroid therapy for underlying rheumatoid arthritis was referred to a university hospital due to presence of several splenic cysts, with the largest being 3.5 cm in diameter. Percutaneous aspiration was performed, and fluid analysis showed cysts infected by extended- spectrum, beta-lactamase-producing Escherichia coli. The patient was treated with ertapenem for four weeks, and the lesion disappeared on follow-up imaging studies. Splenic abscess should be included as a differential diagnosis of splenic cystic lesions in immunocompromised patients. (Korean J Gastroenterol 2018;72:209-212)

Purpose: The purpose of this article is to analysis the results of combined agioplasity and femorofemoral bypass in patients with unilateral iliac arterial occlusive disease. Method: During the 11-year period from 1990 to 2000, 44 patients with iliac artery occlusion and a hemodynamically significant contralateral iliac artery stenosis were treated by using a combination of percutaneous transluminal femoral bypass (n=14) at Korea university medical center. PTA was performed if the lesions in the donor iliac artery were less than 3 ??㎝ in length with in more than one well-localized lesion in either the common or external iliac artery, or both. Stent was deployed for suboptimal PTAs. The femorofermoral bypass was done within 3 to 5 days after PTA or stenting. Result: The mean age was 61.2 years. The Indications of fermorofermoral bypass were hypertension, ischemic heart disease, chronic obstructive lung disease, old age (>75), cancer, and previous abdominal operation, The complication rate of the combination treatment was lower than that of the others. Primary patency rate at 1 and 3 years were 89%, 78% for aortobifemoral bypass, 83%, 66% for iliofemoral bypass, and 77%, 65% for femorofemoral bypass, respectively. Conclusion: The combination of PTA with or without stent deployment and femorofemoral bypass can be a useful option for treating iliac occlusion and contralateral iliac stenosis in patients with severe comorbid illness, advanced age, and intra-abdominal pathology. Angioplasity can allow more widespread use of femorofemoral pypass in these patients.
