The year after aldosterone was isolated and characterized, primary aldosteronism ( PA) was recognised as causing hypokalemia and hypertension, in response to hormone secretion inappropriate for sodium levels. This manuscript deals with three time periods since then: the first sixty five years, its current management in a very active clinic in Melbourne, Australia; and finally some suggestions as to improvements in recognition, diagnosis and management over the next five years. We will suggest improvements that endocrinologists, in China and elsewhere, might consider for what has emerged as a major public health issue.

In capacitive heating device, which considered efficient for deep heating, parallel arrangement of the electrodes is a serious limiting factor in heating for eccentrically located lesions because it causes overheating of the exposed ipsilateral skin surface, the heating pattern is also frequently inappropriate, arid the arrangement tends to be unstable due to the patient's gravity. Therefore we attempted an angular arrangement of the electordes to achieve more homogenous and efficient heating for such lesions. In phantom study, both the thermal profile and thermogram established the heating pattern in this unusual angular arrangement of the electrodes at 60degree, 90degree and 120degree angles, respectively. An angular arrangement was also clinically applied to 3 patients. The patients' tolerance was good without significant complication and the thermal distribution was satisfactory. In conclusion, this unusual arrangement of electrodes appears to be promising in the clinical application to the eccentrically located lesions.

The tuberculous peritonitis, especially in pregnancy, is very rare and difficult to diagnose since there is no diagnostic clue and limitation of diagnostic means. The clinical features may vary such as fever, chill, tachycardia, abdominal tenderness or rebound tenderness which are not controlled easily with antibiotics. It is possible to diagnose by AFB culture and biopsy through exploro-laparotomy which is done due to uncontrolled symptoms even to unstable vital signs. It's clinical symptoms and signs are dramatically improved with antituberculotic therapy. Recently we have experienced a case of tubeculous peritonitis at 29 weeks gestation which was diagnosed through exploro-laparotomy including cesarean section. So we report this case with a brief review of literature

A case of fungemia caused by Cyberlindera fabianii was reported in the September issue of Annals of Clinical Microbiology. The C. fabianii that causes rare invasive infection can easily be misidentified as Candida utilis by Vitek-2 YST ID (bioMerieux, USA) and as Candida pelliculosa by API kit (bioMerieux, USA) with high probability. Recently, we also experienced a case of fungemia caused by C. fabianii that was misidentified as C. pelliculosa using API 20C Aux (bioMerieux, USA). As molecular identification is becoming more widespread, cases of C. fabianii infection are expected to be more frequently identified.

Primary papillary serous carcinoma of the peritoneum(PPSCP) is vere rare. It has been suggested that PPSCP derives from embryonal coelomic epithelium with m llerian ducts potential. PPSCP can develop from a single or multicentric focus. The clinical and histologic disease entities are similar to those of primary papillary serous carcinoma of the ovary, but PPSCP involves the ovarian surface only minimally(microscopic disease) or spares the ovaries entirely. We have experienced a case of primary papillary serous carcinoma of the peritoneum and report this case with brief review of the concerned literature.

Bronchogenic cysts are generally found in the mediastinum, particularly posterior to the carina, but they rarely occur in such unusual sites as the skin, subcutaneous tissue, pericardium, and even the retroperitoneum. A 30-year-old Korean man underwent surgery to remove a cystic adrenal mass incidentally discovered during routine physical checkup. At surgery, it proved to be a multilocular cyst located in the retroperitoneum adjacent to the left adrenal gland. Microscopically, the cyst was lined by respiratory epithelium over connective tissue with submucous glands, cartilage and smooth muscle, thereby histologically confirming bronchogenic cyst. This is the first reported case of retroperitoneal bronchogenic cyst in an adult without other congenital anomalies in Korea.

This report summarizes the 2019 survey results of the external quality assessment (EQA) scheme for the Transfusion Medicine Program (TMP) in Korea. Proficiency testing materials were prepared at the Asan Medical Center for the biannual distribution to participating laboratories. The average accuracy rates and number of participants (in parenthesis) for ten survey items were as follows: ABO typing, 99.4%–99.9% (N=875); RhD typing, 99.8%–100% (N=864); crossmatching, 90.8%–99.6% (N=760); ABO subtyping, 98.2% and 100% (N=58); Rh CcEe antigen testing, both 100% (N=55); weak D test, 97.9%–100% (N=232); antibody screening, 99.7%– 100% (N=316); direct antiglobulin test (DAT) using a polyspecific reagent, 99.6%–100% (N=273); DAT using an immunoglobulin-G monospecific reagent, both 100.0% (N=67); DAT using a C3d monospecific reagent, 95.6%–98.5% (N=67); antibody identification, 87.9%–99.2% (N=132); and ABO Ab titration, 85.7%–100% (N=134). The number of participants showed an average increase of 14% across the ten survey items, with the ABO antibody titration showing the highest increase at 83.6%. While results were generally excellent, antibody identification and ABO antibody titration results showed room for improvement. The 2019 EQA scheme for TMP has contributed to the improvement and maintenance of the participating laboratories to the program.
