Background: Radioiodine therapy has been widely used for thyroid disease patients, but hyposalivation and xerostomia may occur in 10~30% of patients. Sialocentesis is a procedure that removes inflammatory substances in the salivary duct and expands the duct for the secretion and delivery of saliva. In this study, thyroid disease patients treated with radioactive iodine were selected among the patients with xerostomia who visited the hospital, and the effect of sialocentesis was compared and analyzed. And then, comparison between the radioiodine therapy-experienced group and the non-radioiodine therapy-experienced group was conducted. Results: In this study, we studied xerostomia patients who underwent radioiodine therapy due to thyroid diseases and who underwent sialocentesis at the Korea University Anam Hospital. Sialocentesis is conducted by one surgeon. The study also compares the clinical symptoms before and after the surgery. After the procedure, the discomfort due to xerostomia was reduced, and the symptom was improved effectively. Conclusions: The results of this study showed that sialocentesis has a clinical effect in the treatment of xerostomia, which is a side effect of radioiodine therapy. In addition, the possibility of further clinical application of sialocentesis in the future is found.

Sj$\ddot{o}$gren's syndrome (SS) is an autoimmune disorder primarily affecting the salivary and lacrimal glands. In addition, extra-glandular manifestations involving the lungs, liver, kidneys, pancreas, skin and central nervous system were reported in patients with SS. These extra-glandular manifestations are not rare in adult patient, but are very rare in pediatric SS. Renal manifestations are relatively common in adult SS, but are rarely reported in childhood SS. We experienced a girl with primary SS manifested with nephrogenic diabetes insipidus and renal tubular acidosis.

Many diseases occur by stress or effect of stress. The basis for using hormones in research of stress is the observation that most systems in the body show changes during stress and that hormonal markers in these changes are related with stress. Conceptually, the central role of sympathetic nervous system(SNS) and hypothalamus-pituitary-adrenal(HPA) axis activity in stress provides copious justification for measuring hormonal changes. Catecholamines like epinephrine and norepinephrine, cortisol, testosterone and growth hormone and so on show sensitive reaction to stress. The major advantage of salivary sample to stress research is that its sampling technique can be performed in non-stressful conditions and without physical restraint and ethical problems. Because hormone levels in saliva is a good reflection of hormone levels in plasma, application of stress hormones in saliva is very useful for research of orofacial pain related with stress.

Kimura's disease is a chronic inflammatory disorder presenting regional lymphadenopathy with painless soft tissue mass. Clinically, peripheral eosinophilia and elevated serum IgE levels are observed, and proteinuria associated with renal disease can also be present. Although its etiology is not clearly understood, it occurs predominantly in young Asian males and presents as a deep, subcutaneous mass involving salivary glands of the preauricular and submandibular regions. Spontaneous remission is very rare, and although treatments such as steroid, cytotoxic therapy and irradiation are available, chronic recurrence is very common. As such, surgical excision is regarded as the mainstay of therapy for localized lesions. Histopathologically, Kimura's disease features eosinophilic abscsesses and dense lymphoid aggregates with germinal center. Clinical differential diagnosis of Kimura's disease from other parotid diseases with accompanying lymphadenopathy is often very challenging prior to biopsy. The authors report a case of a 19-year-old male diagnosed with Kimura's disease in the parotid region who underwent surgical excision and was followed up for 6 years, along with a review of related literature.

Monocytoid B-cell lymphoma is uncommon, low grade lymphoma originating from monocytoid B lymphocytes. Monocytoid B-cell lymphoma usually presents as a localized lymphadenopathy. Peripheral lymph nodes are most often involved, particularly those in the frequent in the head and neck area. A distinctive feature is the association of monocytoid B-cell lymphoma with autoimmune diseases. Sjogren Syndrome had been present in 22% of patient with monocytoid lymphoma. Extranodal involvement by monocytoid lymphoma was reported in the salivary gland, breast, thyroid, and stomach. There were also occasional extensions to the liver and retroperitoneum. The bone marrow and peripheral blood involvement by monocytoid lymphoma is very rare, which is frequently seen in hairly cell leukemia. Fever, weight loss, and other constitutional signs are usually absent. Most patients have no symptoms, and the only sign is enlarged lymph nodes. The clinical course remains indolent; most patients are in complete remission and recurrence with progression to a high-grade lymphoma of large cell type was recorded only in a few cases. Authors experienced a case of monocytoid B-cell lymphoma associated with Sjogren Syndrome mistaken to simple cervical lymphadenitis in a 60-year-old female. We report this case with a review of literatures.

Background: Previous research has shown that paramedics are exposed to risks in the form of injuries to the musculoskeletal system. In addition, there are studies showing that they are also at increased risk of cardiovascular disease, cancer, and psychiatric diseases, which can partly be explained by their constant exposure to stress. The aim of this study is to evaluate whether the use of shoulder straps decreases physical effort in the form of decreased heart rate and cortisol concentration. Methods: A stretcher with a dummy was carried by 20 participants for 400 m on two occasions, one with and one without the shoulder straps. Heart rate was monitored continuously and cortisol samples were taken at intervals of 0 minutes, 15 minutes, 30 minutes, 45 minutes, and 60 minutes. Each participant was her or his own control. Results: A significant decrease in heart rate and cortisol concentration was seen when shoulder straps were used. The median values for men (with shoulder straps) at 0 minutes was 78 bpm/21.1 nmol/L (heart rate/cortisol concentration), at 15 minutes was 85 bpm/16.9 nmol/L, and at 60 minutes was 76 bpm/15.7 nmol/L; for men without shoulder straps, these values were 78 bpm/21.9 nmol/L, 93 bpm/21.9 nmol/L, and 73 bpm/20.5 nmol/L. For women, the values were 85 bpm/23.3 nmol/L, 92 bpm/20.8 nmol/L, and 70 bpm/18.4 nmol/L and 84 bpm/32.4 nmol/L, 100 bpm/32.5 nmol/L, and 75 bpm/25.2 nmol/L, respectively. Conclusion: The use of shoulder straps decreases measurable physical stress and should therefore be implemented when heavy equipment or a stretcher needs to be carried. An easy way to ensure that staff use these or similar lifting aids is to provide them with personalized, well-adapted shoulder straps. Another better option would be to routinely sewn these straps into the staff's personal alarm jackets so they are always in place and ready to be used.

Purpose: Peripheral artery disease (PAD) is a form of arteriosclerosis that occurs in the extremities and involves ischemia. Previous studies have reported that patients with periodontitis are at high risk for PAD. However, the relationship between these 2 diseases has not yet been fully elucidated. In this cross-sectional study, we investigated this relationship by comparing patients with PAD to those with arrhythmia (ARR) as a control group. Methods: A large-scale survey was conducted of patients with cardiovascular disease who visited Tokyo Medical and Dental University Hospital. We investigated their oral condition and dental clinical measurements, including probing pocket depth, bleeding on probing, clinical attachment level, and number of missing teeth; we also collected salivary and subgingival plaque samples and peripheral blood samples. All patients with PAD were extracted from the whole population (n=25), and a matching number of patients with ARR were extracted (n=25). Simultaneously, ARR patients were matched to PAD patients in terms of age, gender, prevalence of diabetes, hypertension, dyslipidemia, obesity, and the smoking rate (n=25 in both groups). Real-time polymerase chain reaction was performed to measure the bacterial counts, while the enzyme-linked immunosorbent assay method was used to measure anti-bacterial antibody titers and proinflammatory cytokine levels in serum. Results: PAD patients had more missing teeth ($18.4{\pm}2.0$) and higher serum levels of C-reactive protein ($1.57{\pm}0.85mg/dL$) and tumor necrosis factor-alpha ($70.3{\pm}5.7pg/mL$) than ARR patients ($12.0{\pm}1.7$, $0.38{\pm}0.21mg/dL$, and $39.3{\pm}4.5pg/mL$, respectively). Meanwhile, no statistically significant differences were found in other dental clinical measurements, bacterial antibody titers, or bacterial counts between the 2 groups. Conclusions: Our findings suggested that PAD patients had poorer oral and periodontal state with enhanced systemic inflammation.

Importance of accurate molecular diagnosis and quantification of particular disease-related pathogenic microorganisms is highlighted as an introductory step to prevent and care for diseases. In this study, we designed a primer/probe set for quantitative real-time polymerase chain reaction (qRT-PCR) targeting rgpA gene, known as the specific virulence factor of periodontitis-related pathogenic bacteria 'Porphyromonas gingivalis', and evaluated its diagnostic efficiency by detecting and quantifying relative bacterial load of P. gingivalis within saliva samples collected from clinical subjects. As a result of qRT-PCR, we confirmed that relative bacterial load of P. gingivalis was detected and quantified within all samples of positive control and periodontitis groups. On the contrary, negative results were confirmed in both negative control and healthy groups. Additionally, as a result of comparison with next-generation sequencing (NGS)-based 16S metagenome profiling data, we confirmed relative bacterial load of P. gingivalis, which was not identified on bacterial classification table created through 16S microbiome analysis, in qRT-PCR results. It showed that an approach to quantifying specific microorganisms by applying qRT-PCR method could solve microbial misclassification issues at species level of an NGS-based 16S microbiome study. In this respect, we suggest that P. gingivalis-specific primer/probe set introduced in present study has efficient applicability in various oral healthcare industries, including periodontitis-related microbial molecular diagnosis field.

Diffuse infiltrative lymphocytosis syndrome is an autoimmune syndrome that is characterized by the oligoclonal expansion of CD8+ T-lymphocytes in response to human immunodeficiency virus (HIV) antigens. The clinical manifestations include bilateral enlargement of the parotid glands, lymphocytic interstitial pneumonitis, lymphocytic hepatitis, neurological involvement and systemic lymphadenopathies. In addition to a positive HIV test, the diagnostic histopathological findings are CD8+ T-lymphocytic infiltrations in the lymphnodes, liver, lung, muscle and the salivary or lacrimal glands without granulomatous or neoplastic involvement. We report a case of pulmonary involvement of diffuse infiltrative lymphocytosis syndrome that was associated with a human immunodeficiency virus infection.
