The Formosan sika deer (Cervus nippon taiouanus) is an endemic subspecies in Taiwan. The original wild deer has been extinct since the late 1960s. The largest captive population is located at the Taipei Zoo. Except for infectious disease outbreaks, no systemic medical research has been reported for this subspecies. This study was conducted to analyze the medical status of the captive Formosan sika deer population, including the hematological and serum chemistry characteristics. To accomplish this, medical records for 34 Formosan sika deer from January 2003 to January 2014 were acquired and analyzed. The most common illness and cause of death was trauma, followed by gastrointestinal and respiratory disease, respectively. The hematologic and serum chemical values of healthy adults were quite different from those of sika deer (Cervus nippon yesoensis). This study provides a closer medical understanding of this subspecies and the results will facilitate its management.

Parkinson's disease (PD) is the second most common neurodegenerative disease, and 5-10% of the PD cases are genetically inherited as familial PD (FPD). LRRK2 (leucine-rich repeat kinase 2) was first reported in 2004 as a gene corresponding to PARK8, an autosomal gene whose dominant mutations cause familial PD. LRRK2 contains both active kinase and GTPase domains as well as protein-protein interaction motifs such as LRR (leucine-rich repeat) and WD40. Most pathogenic LRRK2 mutations are located in either the GTPase or kinase domain, implying important roles for the enzymatic activities in PD pathogenic mechanisms. In comparison to other PD causative genes such as parkin and PINK1, LRRK2 exhibits two important features. One is that LRRK2's mutations (especially the G2019S mutation) were observed in sporadic as well as familial PD patients. Another is that, among the various PD-causing genes, pathological characteristics observed in patients carrying LRRK2 mutations are the most similar to patients with sporadic PD. Because of these two observations, LRRK2 has been intensively investigated for its pathogenic mechanism (s) and as a target gene for PD therapeutics. In this review, the general biochemical and molecular features of LRRK2, the recent results of LRRK2 studies and LRRK2's therapeutic potential as a PD target gene will be discussed.

Mortality rate and causes of death are regarded as an index of strength as well as level of development of a country. However, there is no accurate data for the causes of death in Korea due to lack of systematic vital data collection system. The objective of this study was to define the causes of death of the school teachers, its changing pattern, cause-specific mortality rate, and geographic variation. The study population included all of the teachers in primary school, middle and high schools, and college who joined in Korean Teachers' Union between 1968 and 1985 that provided a total of 1,972, 069 person-years to observe (1,384,911 man-years, 587,158 woman-years). There were 3,678 deaths in this period (3,377 males, 301 females). The most common cause of death was neoplasm which was followed by the diseases of circulatory system. The proportion of death of neoplasm was 1.5 times higher than that of the general population. Causes of death were classified into 5 major groups (neoplasm, diseases of circulatory system, accidents and poisoning, diseases of liver, and all others). The mortality rates of diseases of circulatory system and all others for general population were 4 to S times higher than those for the teachers. However, mortality rates of neoplasm and diseases of liver were only about 2 times higher than those for teachers. Mortality rate of liver cancer for teachers was higher than gastric cancer mortality rate which is the reverse in general population. The crude death rate was 2.12 per 1,000 person-years for male and 1.00 for female which is one-third of the crude death rate of general population. Crude death rate of study population was higher in rural area than in urban area. However, mortality rate of neoplasm for male was higher in urban area than in rural area while mortality rates of all other causes were higher in rural area. For female, mortality rates of neoplasm and diseases of circulatory system were higher in urban area and the rates for all other causes were higher in rural area. Crude death rate was lowest in Gyeongin area and highest in Yeongnam area. The mortality of neoplasm for male accounted the highest proportion of all death in Gyeongin, Chungcheong and Yeoungnam areas while the mortality of neoplasm and mortality of circulatory system accounted the same proportion in Jeonra area. For female, the mortality of disease of circulatory system accounted the highest proportion in Gyeongin and Yeoungnam and Jeonra areas. Proportion of death due to accidents and poisoning was high in Chungcheong area and death due to all other causes was high in Yeoungnam area. The most common cause of death for male by city and province was neoplasm in Seoul, Busan, Daegu, Gyeonggi, Chungnam, Chungbuk, Gyeongnam and Gyeongbuk. Diseases of circulatory system was the leading cause of death in the rest of city and provinces. The leading cause of death for female was diseases of circulatory system in Seoul, Incheon, Chungbuk, Chungnam, and Gyeongbuk, neoplasm in Busan, and accident and poisons in all other cities and provinces. The mortality rates of male were above 2 per 1,000 person-years in Jeju, Gyeongbuk, Gyeongnam, Daegu, and Chungbuk, and it was below 1.5/l,000 in Seoul, Incheon and Gyeonggi. The mortality rate of female was above 1.2/1,000 person-years in Gyeongnam and Incheon while it was below 0.5/l,000 in Daegu, Geonggi Chungbuk and Jeju. The leading cause for male by school of employment was neoplasm in all levels of school with a remarkably higher rate in the professors of college. Leading cause of death for female was disease of circulatory system in primary schools, high schools and college but neoplasm in middle schools. There was no death due to liver diseases in middle and high school teachers and college professors and no death due to all other category in high school teachers and college professors, in females. High school teachers and the highest mortality rate and college professors showed the lowest mortality rate. Temporal trend of mortality was examined in three periods; period I ($1968{\sim}1974$), period II ($1975{\sim}1979$), and period III ($1980{\sim}1985$). The leading cause of death for male was diseases of circulatory system in period I and II but neoplasm in period III. Such trend of decreasing diseases of circulatory system and increasing neoplasm was observed in female. Overall mortality rate was decreased over the 3 periods. The mortality rates of diseases of circulatory system, liver disease and all others were decreased in male but the mortality rates of neoplasm and accident and posions was increased. Female showed a similar trend to male but the mortality rate of liver diseases was increased. Mortality rates of diseases of circulatory system, neoplasm and liver diseases increased with age of teachers up to 50 years of age but decreased in 60 years of age. Mean age at death due to each cause was higher in male than female by $4{\sim}10$ years. However, the mean age at death of the teachers was $2{\sim}5$ years lower than that of the general population in all causes of death and the sex difference in the mean a2e at death was smaller ($2{\sim}3$ years) in general population. In sex ratio of mortality, male was higher than female in almost all diseases except suicide and maintained a high ratio. The general population showed universally high ratio in male like teachers, and more or less did regular patterns in mortality with ratio smaller.

The pathogen Mycobacterium avium complex (MAC) is the most common cause of nontuberculous mycobacterial pulmonary disease worldwide. The decision to initiate long-term antibiotic treatment is difficult for the physician due to inconsistent disease progression and adverse effects associated with the antibiotic treatment. The prognostic factors for the progression of MAC pulmonary disease are low body mass index, poor nutritional status, presence of cavitary lesion(s), extensive disease, and a positive acid-fast bacilli smear. A regimen consisting of macrolides (clarithromycin or azithromycin) with rifampin and ethambutol has been recommended; this regimen significantly improves the treatment of MAC pulmonary disease and should be maintained for at least 12 months after negative sputum culture conversion. However, the rates of default and disease recurrence after treatment completion are still high. Moreover, treatment failure or macrolide resistance can occur, although in some refractory cases, surgical lung resection can improve treatment outcomes. However, surgical resection should be carefully performed in a well-equipped center and be based on a rigorous risk-benefit analysis in a multidisciplinary setting. New therapies, including clofazimine, inhaled amikacin, and bedaquiline, have shown promising results for the treatment of MAC pulmonary disease, especially in patients with treatment failure or macrolide-resistant MAC pulmonary disease. However, further evidence of the efficacy and safety of these new treatment regimens is needed. Also, a new consensus is needed for treatment outcome definitions as widespread use of these definitions could increase the quality of evidence for the treatment of MAC pulmonary disease.

Parkinson's disease(PD) is a progressive neurodegenerative disease that affects the functioning of the basal ganglia, a brain area that contributes to the control of movement. The disease is caused by the death of nerve cells in the brain that produce dopamine, a chemical messenger. The cells affected usually produce a neurotransmitter(a chemical that transmits nerver impulses) called dopamine, which acts with acetylcholine, another neurotransmitter, to fine-tune muscle control. In Parkinson's disease, the level of dopamine relative to acetylcholine is reduced, adversely affecting muscle control. When the supply of dopamine is depleted, the function of the basal ganglia is disrupted and its ability to control movement deteriorates. The result is that PD patients experience moderate rigidity, difficulty in initiating movements and slowness in executing them, and a rhythmical tremor at rest. Although the cause of Parkinson's disease is not known, genetic factors may be involved. About 3 in 10 people with the disorder have an affected family member. About 1 in 100 people over the age of 60 in the US have Parkinson's disease. And Parkinson's disease is slightly more common in men. The course of the disease is variable, but drugs may be the best effective in treating the symptoms and improving quality of life. But, The doctor may arrange physical therapy to help with physical mobility problems. It is important to continue to exercise and take care of your general health. Try to take a walk each day. Stretching exercises can help you maintain your strength and mobility. So, This papers will serve about the information of PD for clinical physical therapist. Finally, The aim of review is increasing approach method and technique for PD patients by the view of physical therapy.

Diarrheal disease is the second leading cause of mortality and morbidity in children under 5 years old worldwide, and is the most common cause of malnutrition in sub-Saharan Africa. In Rwanda, diarrhea is the third leading cause of death in children under 5 years old. This study examined the association between sociodemographic factors and diarrhea in children under 5 years using the data of 7,474 households in the 2014-2015 Rwanda Demographic and Health Survey. Overall prevalence of diarrhea in this study was 12.7% in children. An increased risk for diarrhea was found for children aged 12-23 months (odds ratio (OR)=4.514), those with a low economic status (OR=1.64), those from the Western province (OR=1.439), those with poorly-educated mothers (OR=5.163), and those with families engaged in agricultural activities (OR=1.624). In conclusion, sociodemographic factors significantly affect the risk of developing diarrhea in children under 5 years in Rwanda. Designing and implementing health education promoting awareness of early interventions and rotavirus vaccination are essential to reduce diarrheal diseases for the Rwandan community.

Salmonella is one of the most important food-borne zoonotic pathogens, causing acute or chronic digestive diseases such as enteritis. The acute form of enteritis is common in young pigs of 2 - 4 months of age. The main symptoms include high fever ($41-42^{\circ}C$), loss of appetite, and increased mortality within 2 - 4 days of onset of the disease. It is often the cause of increasing mortality, decreasing growth rate and reducing feed efficiency of piglets. In the case of chronic enteritis in pigs, the main symptom is weight loss due to the continuing severe diarrhea. Salmonella enterica serovar Typhimurium and Salmonella enterica serovar Choleraesuis are typical pig adapted serotypes, which cause one of four major syndromes: enteric fever, enterocolitis/diarrhea, bacteremia and chronic asymptomatic carriage. These syndromes cause a huge economic burden to swine industry by reducing production. Therefore, it is necessary that swine industries should strive to decrease Salmonellosis in pigs in order to reduce economic losses. There are several measures, such as vaccination to prevent salmonellosis, that are implemented differently from country to country. For the treatment of Salmonella, ongoing antibiotic treatment is needed. However constant doses of antibiotics can be a problem because of antibiotic resistance. Therefore, the focus should be made more on prevention than treatment. In this review, we addressed the basic information about Salmonella, route of infection, clinical symptoms, and prevention of Salmonellosis.

Infections of the oral and maxillofacial region are one of the most common conditions for which a patient presents to a maxillofacial surgeons. Although these infections can arise from a variety of source, dental disease is the most common etiology. So, odontogenic infection are frequently encountered in the practice of oral and maxillofacial surgery. These infections often respond to antimicrobial chemotherapy or surgical intervention, such as extraction of teeth, incision and drainage through clinical features. But, odontogenic infections have the potential to spread via the fascial spaces in the head and neck region, and, they spread to cavernous sinus, deep musculofascial space and other vital structure. We have undertaken clinical studies on infections in the oral and maxillofacial regions by analyzing retrospectively hospitalized patients in the Dept. of Oral and Maxillofacial Surgery, Chonbuk National University Hospital past 5 years from 2000 to 2004. And, the patients' age, sex, medical history, causes of the infection, surgical intervention, and other clinical parameters were reviewed. The obtained results were as follows : 1. The most frequent cause of oral and maxillofacial infection was odontogenic. And in the odontogenic cause, dental caries was the most common cause (47.2%). 2. The most common fascial space involved was the submandibular space (15.7%), followed by the buccal space (14.8%). 3. 60.4% of all patients required surgical drainage of the abscess, endodontic treatment or tooth extraction or periodontal treatment with drainage. 4. The most causative organism isolated from the pus culture were streptococcus viridans (53.9%). 5. Underlying medical problems were found in 136 patients (41.9%), the most common being hypertension (27.9%) and diabetes (14.7%).
