Extravasation necrosis due to intravenously administered fluids and drugs is an increasing problem in hospital practice. The incidence of extravasation is variable but skin necrosis is a potentially devastating complication of intravenous therapy. Local injection of hyaluronidase has been recommended for several types of infusion extravasations. The previous studies found hyaluronidase to be effective in the prevention of necrosis following intradermal nafcillin, 12% dextrose, sodium bicarbonate, aminophylline or vince alkaloids.The objectives of the study are to determine the dosage of hyaluronidase which is effective in reducing extravasation necrosis caused by 10% calcium-gluconate and to establish how soon after this extravasation it must be given to retain its effectiveness.Study I evaluated control versus only normal saline group and normal saline with hyaluronidase groups (dose:75,150,300,450 units; all in volume 2 ml, treatment delay:immediate, 15-minutes delay, half hour delay, one hour delay, three hour delay). Size and rate of eschar were compared between groups. Study II was undertaken to examine the evolution of calcium-gluconate induced soft tissue injury in the rabbit. The histologic findings of extravasation sites were compared between groups. A statistically significant protective effect was found in the treated group versus the nontreated group within 15 minutes to 30 minutes. The most effective protection was achieved by the immediate injection of 300 units dosage of hyaluronidase.In conclusion, in the 10% calcium gluconate-induced extravasation, the given data suggest that one can expect the most protective effect with a 300 units dosage of hyaluronidase and within half-hour delay in the treatment group.

Staphylococcus species are one of prevalent pathogens found in hospitals. Microbes that are a primary cause of nosocomial infection were isolated from a dental and medical environment it may assist the reader to explain what this is and how it differs from the 'dental health care providers and ward health care providers'. To investigate the distribution of staphylococcus species in this environment, we used vitek II to measure drug sensitivity, and further performed biochemical testing. The isolation rate of staphylococcus species from the dental and medical environment was 100% but from dental health care providers and ward health care providers were 44.4% and 33.3%, respectively. In the analyses, staphylococcus species showed resistance to diffusion of cefoxitin and oxacillin discs. These staphylococci may be sufficiently positive for the mecA gene. Our results suggest that staphylococci might be an important cause of nosocomial infection in the dental clinic.

The idiopathic retroperitoneal fibrosis means that proliferation of fibrous tissue in the retroperitoneal cavity influences the aorta, inferior vena cava, psoas muscle and ureter, and its etiology is not found. Especially, when both ureters are compressed, hydronephrosis resulted in uremia are developed progressively, and it may be treated by urinary diversion. We report a case of idiopathic retroperitoneal fibrosis that treated by bilateral pyelo-ileo-neocystostomy and postoperative metabolic derangement that managed successfully with brief review of literature.

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most prevalent pathogens in hospitals. To investigate cross contamination by this bacterium in both dental and medical settings, the pathogens that cause acute pyogenic infection and one of the major microbes responsible for nosocomial infection were isolated from health care providers, nurses and patients. We used VITEK II to measure drug sensitivity, and we further performed biochemical testing, coagulase serotype testing and pulse-field gel electrophoresis (PFGE) for isolated MRSA colonies. The isolation rate of Staphylococcus aureus from nasal swabs was 75.0% from dental health care providers and 18.8% from the medical health care providers. A total of 10 MRSA strains were isolated from 40 health care providers and 2 patients and the prevalent coagulase serotype from patients and health care providers was VII. The antimicrobial drug resistance and partial PFGE types of the isolated MRSA strains showed a similar pattern. These results suggest that MRSA may be one of the principal causes of nosocomial infection in dental and medical hospitals.

Stent dislodgement is a rare complication of complex percutaneous coronary artery intervention and is often associated with significant morbidity. We report a case of stent dislodgement complicated by coronary artery dissection and acute total occlusion of left circumflex coronary artery. Direct expansion of the dislodged stent was performed using parallel wire technique and small balloon. An overlapping stent was implanted for remained coronary artery dissection. Coronary artery flow was restored and ST segment elevation was normalized after successful intervention.
