ABSTRACT
Implant-Assisted Removable Partial Dentures (IARPDs) treatment is being performed in a fully edentulous patient using implant surveyed prosthesis as an abutment. Implant-supported prosthesis as an abutment of IARPDs is classified into screw-retained and cement-retained type according to the retention type, and each has advantages and disadvantages. The EZ crown system (Samwon DMP, Yangsan, Korea) has a cylinder combined with abutment, and the nickel-titanium spring in this cylinder provides a constant force on the zirconia ball to obtain retention in EZ crown system. In this patient, the natural abutment teeth of the mandibular overdenture was hopeless. We planned implant assisted removable partial denture using anterior implant surveyed prosthesis considering functional and esthetical rehabilitation, cost and patient's needs. When fabricating IARPDs using implant as abutment, we could compensate for the shortcomings of existing implant-supported prosthesis retention type and made the design of removable partial denture easy due to using EZ crown system.

Obstructive colitis is a rare inflammatory condition that occurs in a dilated segment of the colon proximal to an obstructing lesion. A 69-year-old patient presented with abdominal pain and distension. The colonoscopy findings revealed a near total obstruction from sigmoid colon cancer. The mucosa of the obstructive lesion was erythematous and hemorrhagic but normal mucosa was found immediately above the 3 cm long obstructive lesion. The proximal bowel of the normal mucosa showed colitis with hemorrhagic mucosal changes and yellowish exudative plaques. Surgery was performed as a segmental resection after placing a metallic stent to decompress the proximal colonic loop. In conclusion, obstructive colitis should be considered if an ulcero-inflammatory lesion with a colonic obstruction and a skip lesion in the proximal colon are detected.

Photodynamic therapy is a promising modality for the palliation of advanced upper gastrointestinal cancer and for the eradication of early neoplastic and pre-neoplastic lesions. It is based on the combination of a photosensitizer that is selectively localized in the target tissue and illumination of the lesion with visible light, resulting in photodamage and subsequent cell death. For early esophageal cancer, esophagectomy has been a standard modality of curative intent. However, accumulated data supports the possibility of PDT replacing surgery as a curative modality. We experienced a case of early esophageal cancer that recurred after esophagectomy. The patient was successfully treated with photodynamic therapy using porfimer sodium as a photosensitizer.

Boerhaave's syndrome is a rare spontaneous rupture of the esophagus that requires an immediate diagnosis and surgical repair. It might result from a severe and uncoordinated contraction of the esophagus and stomach. The rate of mortality and morbidity can increase with increasing time between the onset and treatment. In recent years, there have been some reports of non-surgical treatment in cases with perforation but with minimal symptoms and clinical evidence of the systemic effects such as sepsis. We experienced a case of Boerhaave's syndrome occurring during an endoscopic examination that was treated successfully using non-surgical measures.

Central diabetes insipidus (DI) is a disease caused by insufficient release of antidiuretic hormone. Central DI with lung cancer is very rare. Most of them are caused by the pituitary metastasis, and rarely, by the paraneoplastic syndromes. Central DI is diagnosed by the water deprivation test. The treatment consists of surgical resection, radiotherapy and administration of desmopressin. We report an unusual case of central DI with non-small cell lung cancer. The diagnosis was confirmed by water deprivation test. After the administration of desmopressin, the urine osmolarity was increased. The patient's symptoms and urine osmolarity were improved by intranasal desmopressin.

Sporadic calcification of the left atrium is frequently observed in patients with long standing rheumatic valvular heart disease. However, massive calcification involving the entire left atrium, the so-called porcelain or coconut atrium, is extremely rare. A case of recurrent thrombosis in the left atrium was experienced due to massive calcification of the left atrial wall, despite the therapeutic anticoagulant level of the patient following a surgical thrombectomy.
