Purpose: This randomized clinical placebo-controlled trial was conducted to evaluate the effectiveness of Lactobacillus reuteri as a probiotic in guided pocket recolonization (GPR) for the treatment of chronic periodontitis (CP) adjunctive to scaling and root planing (SRP). Methods: Forty-eight CP patients were randomly assigned to 3 treatment groups: group 1 (SRP+placebo), group 2 (SRP+single application of probiotic), and group 3 (SRP+incremental application of probiotic). Clinical parameters were evaluated at baseline and at 8, 12, and 24 weeks, whereas biochemical parameters were measured at baseline and 12 weeks. Results: At 24 weeks, the probing pocket depth and clinical attachment level improved in all 3 groups from baseline with no significant intergroup differences; however, a statistically significant difference was observed in localized plaque and gingival scores between groups 1 and 3 (P<0.05). At 12 weeks, matrix metalloproteinase-8 (MMP-8), nitric oxide (NO), and gingipains-R (Rgps) levels improved in all 3 groups, with statistically significant differences between groups 1 and 3 for MMP-8 and NO (P<0.05), but no difference for Rgps levels. Conclusions: Within its limitations, the results of this study show that incremental 3-time application of L. reuteri as a probiotic led to improvements in clinical and biochemical parameters. This protocol can be a useful adjunct to SRP in the non-surgical management of CP.

Background and Objective : Carpal tunnel syndrome (CTS) is the most common mononeuropathy encountered in clinical practice. No single procedure or group of procedures has demonstrated adequate sensitivity. F-wave study in CTS is very rarely reported. To determine the diagnostic usefulness of new parameters of F-wave and comparative study of F-wave parameters of median and ulnar nerves in patients with CTS. Methods : F-wave responses of median and ulnar nerves were analyzed from 27 patients with clinically diagnosed CTS and 22 age and gender-matched normal control. Conventional F-wave parameters were studied. Also, the usefulness of new parameters such as mean and maximal ulnar-median F-wave latency differences, ulnar-median F-wave persistence and chronodispersion differences, median/ulnar F-wave amplitude ratio, and F-wave conduction velocity (FCV) using mean and maximal latency were assessed. Results : Compared with controls, median F-wave minimal, maximal and mean latencies, mean F-wave amplitude/M-wave amplitude, minimal, mean and maximal ulnar-median F-wave latency differences, and FCVs using minimal, maximal and mean latency were significant (P<0.05~0.001). Median F-wave minimal, maximal and mean latencies, mean ulnar-median F-wave latency difference, and FCVs using minimal, maximal and mean latency showed high sensitivity and specificity. Mean ulnar-median F-wave latency difference and FCVs using maximal and mean latency were new parameters. Conclusion : New F-wave parameter including mean ulnar- median F-wave latency difference and FCVs using maximal and mean latency may be a useful to assess the CTS. Also, median F-wave minimal, maximal and mean latencies, and FCV using minimal latency may be included in routine diagnostic tests in CTS.

Objectives The purpose of this study was to examine how changes in the cervical spine correlate with body posture changes in the whole body, and to find out the significance of complementary clinical application X-ray and Chuna posture analysis. Methods From January 1, 2019 to October 31, 2019, the results of 27 patients with pain in the vertebral region were analysed in accordance with the results of cervical X-ray and Chuna posture analysis. In order to confirm the significance of Chuna posture analysis results, the survey of 187 Chuna standard curriculum instruction qualification certifiers was conducted and the responses of 47 of them were analyzed. Results The occiput-atlas cline angle increases in both hypolordosis/hyperlordosis groups based on cervical lordosis angle, and increases further than in the hyperlordosis group. There were significant correlations between the changes in the cervical spine and the body posture changes in the whole body. There were no significant differences between cervical X-ray sagittal parameters and the body posture analysis parameters based on the patient's major disease codes. Conclusions As a result of conducting a survey on the clinical importance of the body posture analysis parameters, the importance of cervical parameters was verified. Changes in the cervical spine may not only cause other changes in the cervical region, but also affect the body posture changes in the whole body. The complementary application of X-ray and Chuna posture analysis results is helpful in clinical diagnosis and treatment of musculoskeletal disorders.

Although various automated CBC analyzers with different WBC analytical principles were consequently introduced to clinical laboratory, the specific information concerning the suitability or unsuitability of aging samples is scarce. For this reason, we studied the effect of storage duration and temperature on CBC parameter in SE-9000 (SYSMEX Medical Electronics Co., Ltd., Kobe, Japan), automated CBC analyzer. We tested 32 K3-EDTA specimens with SE-9000 during 72 hours. Specimens were kept at room temperature (RT) and refrigerated and were analyzed at 0 hr, 4 hr, 8 hr, 24 hr, 48 hr and 72 hr after the collection of the specimens. The percentage changes from initial value for each parameters were calculated. Among the CBC parameters, hemoglobin, red blood cell count, mean corpuscular hemoglobin and platelets were stable for the study period at both temperatures. The mean corpuscular volume (MCV), hematocrit (Hct) and red cell distribution (RDW) increased and the mean corpuscular hemoglobin concentration (MCHC) decreased over time at room temperature. These parameters were stable when refrigerated. The leukocyte count was stable during 72hr at RT and when refrigerated. At room temperature, the relative percentages of neutrophils tend to increase, whereas those of lymphocyte and monocytes tend to decrease after 48 hours. When refrigerated, those of neutrophils and monocytes tend to increase, whereas those of lymphocytes tend to decreased over time. CBC parameters of refrigerated specimen were reliable for 72 hr for the exception of differential count from 24 hr but many CBC parameters, such as MCV, Hct, MCHC, RDW and differential count of leukocyte of blood stored at room temperature for 24 hr were unreliable.

The main objective of this study is to evaluate the cost-effectiveness of tafluprost compared with latanoprost in primry open Angle Glaucoma (POAG) or ocular hypertension OH patients in Korea. A decision analytic model was developed from a societal perspective to estimate clinical outcome, drug cost and glaucoma related cost. The model assumes branch like following: successful treatment, switching to other drug, adding other drug, laser or surgery. Treatment success rate is defined as the percentage of patients with elevated IOP achieving <20% reduction, and discontinuation rate is the percentage of patients who were withdrawn due to severe adverse events. A model that is comprised of 1 month cycle length has 1 year. Treatment success rate and discontinuation rate were obtained from published literatures searched in database. Resource utilizations and costs were calculated with national health insurance data and clinical expert opinions. Sensitivity analyses were performed on crucial parameters. Tafluprost is less costly than latanoprost, $609.0 vs $651.2 expected cost. Thus tafluprost was shown to be dominant compared with latanoprost. The results of sensitivity analysis revealed stable across most of the included parameters. According to this study, tafluprost shows more clinical outcome for 1 year than latanoprost. In addition, first-line treatment of tafluprost is a more cost-minimizing strategy associated with POAG or OH compared with latanoprost.

The purpose of this study was to evaluate the relationship between periodontal disease and halitosis, and to develop a detail clinical protocol for assessing halitosis in animals. We measured the periodontal disease parameters, the degree of halitosis using organoleptic scale method and the concentration of volatile sulfur compounds(VSC) using portable sulfide monitor($Halimeter^{TM}$). In this study, VSC levels by $Halimeter^{TM}$ were found to be significantly associated with periodontal disease parameters(plaque index, calculus index)(P<0.05). We also found that conscious sedation did not affect the measurement of VSC levels.

Background: Cefcapene pivoxil hydrochloride, is an ester-type oral cephem antibiotic. This study was performed to compare the pharmacokinetics and evaluate the bioequivalence of two cefcapene pivoxil hydrochloride 75 mg formulations. Method: In a randomized $2{\times}2$ crossover study, sixty healthy male volunteers were randomly assigned into two groups. After a single dose of 75 mg cefcapene pivoxil hydrochloride oral administration, blood samples were collected at specific time intervals from 0-12 hours. The plasma concentrations of cefcapene pivoxil hydrochloride were determined by LC-MS/MS. The pharmacokinetic parameters were determined from the plasma concentration-time profiles of both formulations. The pharmacokinetic parameters such as $AUC_{last}$, $AUC_{inf}$ and $C_{max}$, were calculated and the 90% confidence intervals for test/reference ratio for pharmacokinetic parameters were obtained by analysis of variance on logarithmically transformed data. Results: The mean value for $AUC_{last}$ in test and reference drug was $4053.1{\pm}876.5\;ng{\cdot}hr/mL$ and $3595.7{\pm}1029.1\;ng{\cdot}h/mL$, respectively. The mean value for $C_{max}$ in test and reference drug was $1324.9{\pm}321.4$ ng/mL and $1159.1{\pm}335.9$ ng/mL, respectively. The 90% confidence intervals of the $AUC_{last}$ and $C_{max}$ ratio for test drug and reference drug were log 1.09-log1.22 and log 1.09-log1.24, respectively. No adverse events were reported by subjects or found on analysis of vital signs or laboratory tests. Conclusion: This single dose study found that the test and reference products met the regulatory criteria for bioequivalence in these health volunteers. Both formulations were safe and well tolerated in 75 mg of cefcapene pivoxil hydrochloride.

Background: Malnutrition of inpatients has been associated with higher morbidity, mortality, cost, and longer hospital stay. Total parenteral nutrition (TPN) therapy plays an important role in decreasing morbidity and mortality among critical inpatients in hospitals, and has been commonly used to improve clinical outcomes. However, only a few studies were conducted regarding patients' nutritional improvement by TPN. Method: This study therefore evaluated the changes in nutritional parameters by TPN therapy for early malnourished inpatients. Data from early malnourished inpatients who were treated with TPN therapy between January 2012 and June 2013 at the ${\bigcirc}{\bigcirc}$ university Hospital were studied retrospectively. Information regarding sex, age, underlying diseases, division, TPN (peripheral and central), and changes in nutritional parameters were collected by reviewing electronic medical records. The criteria for evaluation of the changes in nutritional parameters were included physical marker, body mass index (BMI), and biochemical markers, including albumin (Alb), total lymphocyte count (TLC), and cholesterol. Nutritional parameters were collected three times: pre-TPN, mid-TPN and end-TPN. A total of 149 patients (peripheral, 97; central, 52) was evaluated. Results: In all patients, the malnutrition number was significantly decreased following the complete TPN therapy (peripheral patients, pre-TPN: $3.33{\pm}0.12$, mid-TPN : $3.06{\pm}0.17$, and end-TPN: $2.85{\pm}0.21$ (p < 0.05); central patients, pre-TPN: $3.38{\pm}0.11$, mid-TPN: $3.06{\pm}0.13$, and end-TPN: $2.75{\pm}0.21$ (p < 0.05). The malnutrition number means number of nutrition parameters below normal range of malnutrition. In addition, all of the four nutritional parameters (BMI, Alb, TLC and cholesterol) were increased with duration of TPN periods for all patients, and the changes in the early stage were larger than in the late stage (p < 0.05). The nutritional parameters of non-cancer patients were increased to a greater extent compared to cancer patients with longer TPN therapy, but it was not significant. The nutritional parameters of younger patients (50-60 years) were also increased more than of older patients (70-80 years), but it was not significant. Conclusion: In conclusion, the TPN therapy decreases malnutritional status and improves nutritional parameters in malnourished patients, thereby decreasing morbidity and mortality. The combined evaluation of all four nutritional parameters is more accurate for nutritional assessment than a single one.
