1.Book Review: “The New Microbiology: From Microbiomes to CRISPR”
Annals of Clinical Microbiology 2022;25(2):67-71
At the time when owing to COVID-19 pandemic, the public is more interested in infectious diseases and pathogens than in any other period, a book titled “The New Microbiology: From Microbiomes to CRISPR” by the renowned microbiologist Pascale Cossart was translated and published by our colleague. In this book, the author describes important discoveries and new conceptual advances in the field of microbiology over the past century. The author emphasizes that bacteria form a microbiome and lead a social life and explains the impact and importance of the microbiome on human health and ecosystem. Further, the discovery of ‘CRISPR,’ which led to the era of genome editing and gene therapy, has been described in details. This book will dramatically change our perspective regarding all living things, including bacteria, plants, animals, and even insects, as well as our eating habits and daily life, based on the new understanding of microorganisms. I recommend reading this book as I am sure that it will broaden the perspectives of both clinical microbiologists and health care workers.

Congenital hepatic fibrosis is an inherited, congenital disorder of the liver, and is occasionally associated with cystic disease of the liver and kidney. We present a case of congenital hepatic fibrosis with Caroli's disease. A 21-year-old woman had suffered from an episodic fever with headaches for 3 years. In laboratory examination, the liver function test was within the normal limits. Esophageal varix was noted by an endoscopic examination. Hepatosplenomegaly and multiple dilated bile ducts were seen by abdominal CT scanning. An orthotopic whole liver transplantation was done. The liver was fibrotic and enlarged. Multiple cystically dilated intrahepatic ducts were noted. Microscopically, diffuse portal fibrosis and widening with proliferation of bile ductules were seen. Intrahepatic bile ducts were markedly dilated and tortuous. The liver cell cords were well preserved.

To evaluate the frequency of EM A and Ki-I antigen expression in the large cell lymphoma and to define the histologic characteristics of Ki-1 positive anaplastic large cell lymphoma, 40 cases of malignant lymphoma, diffuse large cell type were immunostained by Ki-I and EMA monoclonal antibodies. Eight cases of large cell lymphomas expressed EMA, among which 4 cases were positive for Ki-I antibody as well. The positive rate for EMA was much higher in T cell lymphomas than in B cell lymphomas. Among 4 cases of Ki-I positive lymphomas, 2 cases showing membrane staining of Ki-1 with prototypic histologic feature of anaplastic large cell lymphoma were classified as Ki-1 positive anaplastic large cell lymphoma(ALCL). Ki-I positive ALCL were T-cell in one and non-T, non-B cell type in the other, respectively. The remaining 2 cases of Ki-1 positive lymphomas showing cytoplasmic staining were classified as both B-cell centroblastic/centrocytic lymphoma and T-cell pleomorphic large cell lymphoma.

BACKGROUND: Rapid screening of vancomycin-resistant enterococci (VRE) is very important for controlling and preventing the spread of VRE in hospitals. We compared the performance characteristics of a chromogenic agar (ChromID VRE, bioMerieux, France: CA) to that of Enterococcosel agar (supplemented with 6 microgram/mL of vancomycin :EA) for direct detection of VRE from stool swabs. METHODS: Total 125 rectal swabs were collected from 57 patients in the intensive care units of an 850-bed university hospital over a period of 3 months. The samples were inoculated on EA, CA and into broth enrichment containing 6 microgram/mL of vancomycin (BE). BE was subcultured on CA after overnight incubation. RESULTS: Eighty two samples from 22 patients were positive for VRE by BE. At 24 h, the sensitivity/specificity of EA and CA were 89%/100% and 72%/100%, respectively. At 48 h, the sensitivity/specificity of EA and CA were 94%/89% and 89%/100%, respectively. CONCLUSION: CA provides equivalent sensitivity comparable to EA for the recovery of VRE at 48 h incubation, and has additional advantage of being able to differentiate between vancomycine resistant E. faecium and E. faecalis.

Core tissue for histologic study is believed by many pathologists to be more diagnostic than material from needle aspiration. Recently introduced automated biopsy gun simplifies core biopsies with increased quantity and quality of samples. Authors performed 38 percutaneous biopsies from 38 patients with 18G automated biopsy guns under US guide. Diagnostic target tissues were obtained in 33 biopsies(87%), inadequate tissues in 4 (11%), and adequate but not of target tissue in 1(3%). There was no major complication requiring treatment, but pain needing analgesics and pain with nausea/vomiting were experienced in 2 and 1 biopsies respectively. Average number of needle passes was 1.5(1-5) We concluded that US-guided gun biopsy was a easy and safe way to obtained tissue samples of good quantity and quality, especially useful in hospitals without constant availability of specialists in cytopathology.

The duration of the phases of left ventricular systole was measured from simultaneous recordings of the electrocardiogram, phonocardiogram and carotid arterial pulse tracing using a multichannel photographic system with paper speed at 100 mm per second. Observations were made in 81 male and 66 female patients with hypertension and 41 healthy males and 38 healthy females who served as controls. All hypertension patients were classified by change in funduscopic finding, EKG and grade of diastolic pressure. STI were measured in each group and analysed. The resutls were as follows: 1. The normal PEP/LVET was 0.293 in male and 0.303 in female. 2. In male & female hypertensive patients, all STI were significantly difference to that of normal control except QA2. 3. In male hypertensive patients, the degree of EKG, funduscopic change and diastolic pressure were positive relation to the increase of PEP/LVET.

Moraxella lacunata is part of the normal flora of the mucosal surface and skin. It is considered to have low pathogenic potential and has been known to cause eye infection but rarely systemic infection. We experienced a case of septicemia due to M. lacunata in a 28-year-old man who was admitted to our hospital due to high fever. He had been well untill 3 weeks earlier when he experienced fever. Physical examination revealed no audible heart murmur and echocardiogram revealed no remarkable abnormalities. Culture of blood revealed M. lacunata. The patient expired due to subdural hemorrhage, 12th days after admission. We report the case with a brief review of related literature.

This study is a methodical research to develop a health behavior assessment scale for patients with rheumatoid arthritis, and to test the validity and reliability of the instrument. The research procedure was as follows; 1) The first step was to develop conceptual framework based on a comprehensive review of the literature, in-depth interviews patients with rheumatoid arthritis. This conceptual framework was organized in eight dimensions; pain management, exercise, rest, diet control, active committment, self-management, positive thinking, interpersonal maintenance. Initially 56 items were selected from 164 statement. 2) These items were reviewed by panel of eight specialists and the Index of Content validity (CVI) was calculated, and forty six items were selected which met more than 70% on the CVI. 3) 174 rheumatoid arthritis pateints were interviewed, and data was gathered from Jan. 25 to Feb. 18, 1999 for test reliabilities and validities of the scale. The item analysis was carried out and 40 items were selected. Factor analysis by varimax rotation was carried out to test construct validity. The internal consistency by chronbach's alpha was calculated. The findings were as follows; 1) Item analysis and factor analysis were carried out to test the validity of the health behavior assessment scale. The item analysis was based on the corrected item`s to total correlation coefficient (.30 or more), and information about the alpha estimate. However, this was only if this item was deleted from the scale. As a result of the item analysis, forty items were selected. Thirty items were selected by a initial factor analysis by varimax rotation, and ten items were deleted because of factor complexity. In the secondary factor analysis, eight factors were labled as 'positive thinking', 'exercise', 'rest', 'pain management', 'active committment', 'self-management', 'diet control', and 'interpersonal maintenance', each similar with the conceptual framework. 2) Chronbach's alpha coefficient to test reliability of the scale was. 903 for total the thirty items. The Scale for assessing health behavior developed in this study was identified to be a tool with a high degree of reliability and validity. Therefore this scale can be effectively utilized for assessment in the health behaviors of the patients with rheumatoid arthritis.
