Electrode contact resistance is a crucial factor in physiological measurements and can be an accuracy limiting factor to perform electrical impedance measurements. The electrical bio-impedance values can be calculated by the conductivity and permittivity of underlying tissue using implant electrode in human skin. In this study we focus on detecting physiological changes in the human skin layers such as the sebum layer, stratum corneum layer, epidermis layer, dermis layer, subcutaneous fat and muscle. The aim of this paper is to obtain optimal design for implantable electrode at subcutaneous fat layer through the simulation by finite element methods(FEM). This is achieved by evaluating FEM simulations geometrically for different electrodes in length(50 mm, 70 mm), in shape(rectangle, round square, sexangle column), in material(gold) and in depth(22.325 mm) based on the information coming from the subcutaneous fat layer. In bio-impedance measurement experiments, according to electrode shapes and applied voltage, we have ascertained that there was the highest difference of bio-impedance in subcutaneous fat layer. The methodology of simulation can be extended to account for different electrode designs as well as more physical phenomena that are relevant to electrical impedance measurements of skin and their interpretation.

Paragonimiasis is a parasitic infection that occurs following the ingestion of infectious Paragonimus metacercariae from crabs or crayfish. Pulmonary paragonimiasis is the most common clinical manifestation of this infection, but several ectopic paragonimiasis cases have also been reported. Among them, cases of subcutaneous paragonimiasis are rare, especially in children. We report a case of subcutaneous paragonimiasis of the right abdominal wall with pleural effusion with hepatic involvement and without abnormal pulmonary infiltration in a boy aged 2 years and 5 months. He had eaten soybean sauce-soaked freshwater crabs (kejang) 6 months prior to complaining of right abdominal wall distension. On evaluation, right pleural effusion without abnormal pulmonary infiltration was detected, as well as blood eosinophilia, an elevated serum IgE level, pleural fluid eosinophilia and a positive enzyme-linked immunosorbent assay that detected P. westermani antibody in the serum. Thoracentesis, praziquantel administration, and excision of subcutaneous lesions were performed. After treatment, the eosinophil count and serum IgE level were decreased, and the subcutaneous lesions did not recur. The frequency of paragonimiasis has decreased recently, but it is still prevalent in Korea. Paragonimiasis should be suspected if pleural fluid eosinophilia is associated with blood hypereosinophilia and a high level of serum IgE; however clinicians should obtain a thorough history of travel and food habits.

A 10-year-old spayed female Pomeranian dog weighing 3.65 kg was presented with a 7-month history of urinary incontinence, stranguria and hematuria. The patient had mass lesions at left prescapular region ($3cm{\times}3cm$) and left axillary region ($5cm{\times}4cm$). Diagnosis of transitional cell carcinoma (TCC) with multiple cutaneous metastasis was made. Dog was treated with chemotherapy using mitoxantrone and piroxicam for 5 months. Although TCC size of urinary bladder was decreased during chemotherapy, there was no change of subcutaneous tumor size and mild relief of clinical signs. Partial anorexia for 3 weeks and multiple masses were noted at left caudal abdominal wall and left medial thigh (203 days after first presentation) and assessed as chronic kidney disease and additional subcutaneous metastasis of urinary bladder TCC by post-mortem and histopathological findings.

Total implanted central venous port (TIAP, Chemoport) is widely used in oncology patients because it does not require external dressing and restricts patient activity. Chemoport only requires monthly flushes of heparinized saline to keep the patency of the catheter and probably less prone to infectious complications than tunneled catheter. Despite the extensive use of permanent central venous access in oncology patients, there are only few reports about clinical experience of the Groshong catheter. The purpose of this study is to compare the complication rate between the traditional open-ended (non-valved) chemoports and valved chemoports (Groshong catheter connected to TIAP). During 5 years (Jan 2006 to May 2010), 438 patients received chemoport insertion procedure in our interventional radiology department. Among them 30 patients was referred to our department for problematic chemoports. We compared the cause of problematic chemoports between two types of chemoports (valved, vs. non-valved). Valved chemoports had higher referral rates than non-valved chemoports. When there is a need to insert valved port, different method of insertion and maintenance procedure seems to be necessary. More than 20 ml of flusing with heparinized saline after blood sampling could be a good suggestion. Adequate care of chemoport is essential for long patency. Also following the guideline from the manufacturing company is necessary.

혈액등 체액이 접촉되는 성 활동과 수혈등 혈액 오염으로 감염되므로 이를 피하여야 한다. 감염가능성이 있는 대상자와의 성생활을 피해야 하며 부득이한 경우 콘돔의 사용이 요구된다.
