  • Patients with febrile illness and skin rashes need full and immediate attention. In general, these diseases show mild manifestations and good prognosis. However, causalities of some diseases with fever and rash may be life threatening or trivial. So, the differential diagnosis for those patients is extensive. A through history, a careful physical examination and close observation of clinical progress are very helpful and essential to confirming the diagnosis. Histories of recent travel, drug or specific food ingestion, exposure to human or an animal source of infection may be useful to discover the cause. Although laboratory tests can be useful in making the diagnosis, laboratory results usually are not available immediately. Knowledge and experiences of such diseases may be helpful to reduce the differential diagnosis to a few major possibilities. Rashes can be categorized as petechial, maculopapular, vesicular, urticarial and erythematous. Potential causes include infectious pathogens such as virus, bacteria, rickettsiae, spirohetes, connective tissue diseases, allergic diseases and heamto-oncologic diseases. Because the severity of these diseases can vary mild to life threatening, physicians must perform prompt management decisions regarding empirical therapies. In this article, the differential etiological diagnosis of each type rash is reviewed and discussed, and with emphasis on intensive care of life threatening febrile diseases with rashes that are seen in our country.

  • Eosinophilic cystitis (EC) is a rare inflammatory disorder in dogs. Although EC has been associated with various etiological factors, the precise cause of this disease remains unclear in human and animals. A 7-year-old female Yorkshire terrier was presented with 3-week-history of hematuria, dysuria, and suprapubic pain. A bladder mass in ventral surface and urinary calculi were noted on ultrasonography and gross findings. Biopsy sample was taken from the protruded mass of bladder for histopathologic examination. Hyperplastic transitional epithelium with focal ulceration covered the bladder mass. A large nodule of fibrous tissue that contained fibrocytes, fibroblasts, Iymphocytes, plasma cells, macrophages, numerous eosinophils, and abundant blood vessels was occupied in lamina propria and submucosa of bladder mass. Based on the clinical, gross, and histopathologic examinations, this case was diagnosed as EC in a dog. In our knowledge, this is the first report of an eosinophilic cystitis in dog in Korea.

  • The report describes an avian mycobacteriosis in a captive wild bird. A 7-year-old female Indian peafowl (Pavo cristatus) maintained in a zoo of Korea presented a gradual cachexia and eventually was found dead. At necropsy, severely atrophied pectoral muscles exposing the keel bone were noticed. Yellowish thick nodules in varying sizes were scattered in all lobes of lungs, liver and spleen, suggesting mycobacteriosis. Histopathologically, multifocal to coalescing granulomas surrounded by multinucleated giant cells were observed. Numbers of acid-fast bacilli were revealed in granulomas. Then, a series of molecular diagnostic techniques were followed: a nested PCR, DNA sequencing and bioinformatics analysis. It resulted as Mycobacterium genavense. The identification of M. genavense as an etiological agent suggested that it might serve as a risk factor for other captive wild animals, and for a potential zoonotic risk since M. genavense have been a definite cause of disseminated mycobacterial infection in immunocompromised people. To the authors' knowledge, this is the first report of avian mycobacteriosis with M. genavense in a captive Indian peafowl.

  • This mini review focuses on foodborne illnesses and outbreaks caused by food-producing animals because statistical information of the foodborne illnesses is important in human health and food industry. Contaminated food results in 600 million cases of foodborne diseases and 420,000 deaths worldwide every year. The world population is currently 7.8 billion, and 56 million people die every year; of these, every year, 7.69% of people experience foodborne diseases, and 7.5% of annual deaths (56 million deaths) was died by foodborne illness in the world. A majority of such patients are affected by norovirus and Campylobacter. Listeria monocytogenes is the most fatal. In the United States, except for those caused by Campylobacter, the number of foodborne diseases did not decrease between 1997 and 2017, and cases caused by Toxoplasma gondii are still being reported (9 cases in 2017). The percentage of foodborne illnesses caused by food-producing animals was 10.4%-14.1% between 1999 and 2017 in the United States. In Europe, foodborne illnesses affect 23 million people every year and cause approximately 5,000 deaths. Europe has more Campylobacter- and Salmonella-related cases than in other countries. In Australia, the highest number of cases are due to Campylobacter, followed by Salmonella. In Korea, Escherichia coli followed by norovirus. Campylobacter- and Clostridium perfringens-related cases have been reported in Japan as well. This review suggests that Campylobacter, Salmonella, L. monocytogenes, and E. coli, which are usually isolated from animal-source food products are associated with a high risk of foodborne illnesses.

  • Gastric cancer (GC) is a significant cause of cancer mortality which has led to focused exploration of the pathology of GC. The advent of genome-wide analysis methods has made it possible to uncover genetic and epigenetic fluctuation such as abnormal DNA methylation in gene promoter regions that is expected to play a key role in GC. The study of gastric malignancies requires an etiological perspective, and Helicobacter pylori (H. pylori) was identified to play a role in GC. H. pylori infection causes chronic inflammation of the gastric epithelium causing abnormal polyclonal methylation, which might raise the risk of GC. In the last two decades, various pathogenic factors by which H. pylori infection causes GC have been discovered. Abnormal DNA methylation is triggered in several genes, rendering them inactive. In GC, methylation patterns are linked to certain subtypes including microsatellite instability. Multiple cancer-related processes are more usually changed by abnormal DNA methylation than through mutations, according to current general and combined investigations. Furthermore, the amount of acquired abnormal DNA methylation is heavily linked to the chances of developing GC. Therefore, we investigated abnormal DNA methylation in GC and the link between methylation and H. pylori infection.

  • Powered infant formula and baby food contaminated with Enterobacter sakazakii were reported to cause infection among infants and to be associated with sporadic cases and outbreaks of sepsis, menigitis, cerebritis, and necrotizing enterocolitis. Salmonella contamination of infant formula has also been responsible for multiple outbreaks. Other species of Enterobacteriaceae in powdered infant formula may be causative agents, about which there has been no report. Other pathogenic bacteria have been isolated from powdered infant formula but they were not associated with outbreaks among infant. While Enterobacter sakazakii caused disease in all age groups, premature infants under 28 days old and with birth weight are most sensitive to its infection. Even if low contamination level of the bacteria in powdered infant formula and baby food may not cause infection, the possibility to multiplicate during preparation and storage of reconstituted formula may increase. The etiological factors and pathogenecity of S. sakazakii have not been elucidated. There were wide variability in phenotype and genotype between its strains. S. sakazakii has been isolated from factory facility and surroundings more frequently than Salmonella and thus factory environment should be the source for post-processing contamination of the formula with S. sakazakii. Considering current technology to manufacture power infant formula and baby food it is impossible to sterilize powdered formula but the frequency of outbreak hazard by S. sakazakii can be reduced by pasteurizing the formula base before drying and shortening storage time of the reconstituted formula.

  • Halitosis, defined as an unpleasant oral odor, is a commonly experienced condition with a variety of etiological factors and may cause a significant social or psychological handicap to those suffering from it, In most cases, halitosis originates within the oral cavity itself and patients with periodontal disease often suffer from oral malodor, The most common cause of this disease is related to microbiota which reside on the tongue and in the periodontal pocket, This study was undertaken to examine the effect of full mouth disinfection including tongue scraping on oral malodor in a group of patients with chronic periodontitis, The relationship between halitosis and oral health status was also investigated, The volatile sulfur compounds (VSC) scores were significantly correlated with Plaque Index, Bleeding Index, pocket depth, and tongue coating score, The organoleptic ratings were significantly associated with Plaque Index, Bleeding Index. and tongue coating score, The VSC scores and organoleptic ratings correlated strongly with each other. Full mouth disinfection resulted in a significant reduction in the VSC scores. organoleptic ratings, and self-perception of malodor up to 12 weeks, This study indicates that in patients with chronic periodontitis. a full mouth disinfection including tongue scraping has a significant effect in the treatment of oral malodor.

  • The sacroiliac joints connect the base of the sacrum to the ilium. When inflamed, they are suspected to cause low back pain. Inflammation of the sacroiliac joints is called sacroiliitis. The severity of the pain varies and depends on the degree of inflammation. Sacroiliitis is a hallmark of seronegative spondyloarthropathies. The presence or absence of chronic sacroiliitis is an important clue in the diagnosis of low back pain. This article aims to provide a concise overview of the anatomy, physiology, and molecular biology of sacroiliitis to aid clinicians in the assessment and management of sacroiliitis. For this narrative review, we evaluated articles in English published before August 2019 in PubMed. Then, we selected articles related to the painful manifestations of the sacroiliac joint. From the retrieved articles, we found that chronic sacroiliitis may be caused by various forms of spondyloarthritis, such as ankylosing spondyloarthritis. Sacroiliitis can also be associated with inflammatory bowel disease, Crohn's disease, gout, tuberculosis, brucellosis, and osteoarthritis, indicating common underlying etiological factors. The pathophysiology of sacroiliitis is complex and may involve internal, environmental, immunological, and genetic factors. Finally, genetic factors may also play a central role in progression of the disease. Knowing the genetic pre-disposition for sacroiliitis can be useful for diagnosis and for formulating treatment regimens, and may lead to a substantial reduction in disease severity and duration and to improved patient performance.
