Lithium 투약도중 과나트륨혈증과 섬망을 동반한 신장성 뇨붕증 환자 1례

Lithium is a widely used important drug in the treatment of manic-depressive illness and its prevention of relapse. However, this drug has a Low therapeutic index, therefore, it has many attendant side effects. The most prevalent renal effect of lithium is impairment of concentrating ability and this defect appeared into overt polyuria. A renal lesion is confined to the collecting tubule and 12-20% of patients taking lithium suffer from nephrogenic diabetes insipidus. This nephrogenic diabetes insipidus causes the states of extracellular fluid depletion, hypernatremia and precipitates lithium intoxication. In such situation, symptoms of nephrogenic diabetes insipidus and lithium intoxication are very similar, so we should be very cautious to discriminate them. We herein report a patient characterized by a prolonged stuporous state, hypernatremia and severe nephrogenic diabetes insipidus during lithium therapy.
Implant의 상부 Abutment를 이용한 전치부 심미회복의 방법과 증례

The purpose of this study was to recover aesthetic aspects and functional aspects of front teeth without damaging or removing the adjacent natural teeth using implant fixture and other various kinds of superstructures when front teeth are lost or damaged. Each case contains the laboratory side and the final status of the patient. These cases showed that the patients had recovered confidence through the recovery of functions and the beauty of the teeth. However there should be continuous efforts such as treatment of portent of gum inflammation and its curing in implant fixture, and selection and operation of appropriate superstructures. Better effects can be expected in assistance of implant fixture without natural teeth because the patients can have brighter smile and bigger confidence.
VITA VM9 Zirconia powder를 이용한 Cerec inlab의 임상증례에 관하여
정효경,김정숙,이종도 대한치과기공학회 2007 대한치과기공학회지 Vol.29 No.2
Although there are many different ways that restorations can be made, it can be said that the biocompatibility of abutment and crown is very important in this experiment. When placed in the actual oral cavity, the differences were obvious. Compared to In-ceram Aluminium, the structure that is obtained after firing reveals a particularly homogeneous distribution of the crystal and glass phase. The In-ceram aluminium system had many problems, such as having weak tensile strength, and having low bonding strength due to the shrinking that occurs after firing. Because of the opaque finish of the metal frame, the two may look similar from the outside, but it is evident that there are differences between using a metal frame and In-ceram. VITA VM9 has been designed as a special ceramic featuring a fine structure or stabilized Zro2 substructures, and so the VITA VM9 excels in its light refraction and reflection behavior, which is similar to natural teeth. It also has outstanding chemical balance, which presents advantages such as considerably reduced accumulation of plaque on the ceramic surface.? This ultimately results in easier care and cleaning for the patient.
