ABSTRACT

Far-infrared rays (FIR) are known to have various effects on atoms and molecular structures within cells owing to their radiation and vibration frequencies. The present study examined the effects of FIR on gene expression related to glucose transport through microarray analysis in rat skeletal muscle cells, as well as on mitochondrial biogenesis, at high and low glucose conditions. FIR were emitted from a bio-active material coated fabric (BMCF). L6 cells were treated with 30% BMCF for 24 h in medium containing 25 or 5.5 mM glucose, and changes in the expression of glucose transporter genes were determined. The expression of GLUT3 (Slc2a3) increased 2.0-fold (p < 0.05) under 5.5 mM glucose and 30% BMCF. In addition, mitochondrial oxygen consumption and membrane potential (ΔΨm) increased 1.5- and 3.4-fold (p < 0.05 and p < 0.001), respectively, but no significant change in expression of Pgc-1a, a regulator of mitochondrial biogenesis, was observed in 24 h. To analyze the relationship between GLUT3 expression and mitochondrial biogenesis under FIR, GLUT3 was down-modulated by siRNA for 72 h. As a result, the ΔΨm of the GLUT3 siRNA-treated cells increased 3.0-fold (p < 0.001), whereas that of the control group increased 4.6-fold (p < 0.001). Moreover, Pgc-1a expression increased upon 30% BMCF treatment for 72 h; an effect that was more pronounced in the presence of GLUT3. These results suggest that FIR may hold therapeutic potential for improving glucose metabolism and mitochondrial function in metabolic diseases associated with insufficient glucose supply, such as type 2 diabetes.

ABSTRACT

Background and Objectives@#Claudin-1 (CLDN-1) is the major component of tight junctions and functions in controlling cell to cell adhesion. Certain claudins were expressed aberrantly and proved to have prognostic significance in various human cancers. However, its clinical significance has been poorly understood in head and neck squamous cell carcinoma (HNSCC). The aim of this study was to investigate the relationship between CLDN-1 expression and clinicopathologic parameters in HNSCC.Subjects and Method The surgical specimens of primary HNSCCs from a consecutive cohort of 91 patients were retrospectively collected. Immunohistochemical staining for CLDN-1 was performed blindly by two pathologists. CLDN-1 staining intensity was scored semi-quantitatively on a scale of 0 to 3 (0: negative; 1: weak; 2: moderate; 3: strong). For the statistical analysis, the expression levels were classified as low (negative and weak) and high (moderate and strong). Next, the association between CLDN-1 expression and clinicopathological features & clinical outcomes was analyzed. @*Results@#The increased CLDN-1 expression was significantly associated with lymphatic invasion (p=0.019). The expression level of CLDN-1 was not associated with pathological T stage, lymph node metastasis or recurrence. Kaplan-Meier analysis found that 3-year overall survival (OS) rate was 53% in patients with high level CLDN-1 expression and 74% in patients with low level CLDN-1 expression. It also found that 5-year OS rate was 49% in patients with high level CLDN-1 expression and 68% in patients with low level CLDN-1 expression. A significantly poor OS rate was recorded in patients with high level of CLDN-1 expression compared to patients with low level CLDN-1 expression (p=0.022). @*Conclusion@#CLDN-1 may serve as useful prognostic marker in patients with HNSCCs.

ABSTRACT

Parotid mass with facial palsy is often suggestive of malignancy. Facial palsy is present in 12% to 19% of patients with a malignant parotid mass regardless of tumor size. Xanthogranulomatous sialadenitis is a rare chronic inflammatory disorder. This is characterized by suppurative granulomatous inflammation and progressive destruction of the normal parenchyma. Since its first report in 1993, xanthogranulomatous sialadenitis has been reported in no more than 10 reports abroad, and to our knowledge, it has never been reported in Korea. It is hard to distinguish clinically xanthogranulomatous sialadenitis from malignancy because they have similar clinical symptoms and radiologic findings, so they should be diagnosed with pathologic methods. With a review of literature, the authors report a case of a parotid mass considered malignant in a 62-year-old, who has complained of a painful right parotid mass and ipsilateral facial palsy. The patient was managed by superficial parotidectomy and conservative antibitoic therapy.

ABSTRACT

Research on physical activity and health is actively being conducted. In the Korea National Health and Nutrition Examination Survey (KNHANES), the Global Physical Activity Questionnaire (GPAQ) was newly introduced in 2014. The purpose of this study was to investigate the levels of physical activity and related factors in Koreans who were assessed through the GPAQ by dividing the physical activity by occupation, leisure, and transport domain. This study used data from the KNHANES (2014–2016), the study population of which included 17,357 participants aged 12 to 80 years. We compared the differences in physical activity by sociodemographic factors, health-related factors, and psychological health-related factors. Moreover, we also compared the mean metabolic equivalent of task and daily sitting time according to physical activity domain by sex and age group. Finally, we investigated the sociodemographic factors, health-related factors, and psychological health-related factors that significantly affect the average physical activity per week. The various factors were found to differ in the frequency of physical activity levels. In addition, there was a difference in the amount of physical activity per occupation, leisure, and transport domain in each age group. Finally, age, sex, high-density lipoprotein cholesterol levels, arthritis, allergic rhinitis and sinusitis, sleeping time, and perceived health status significantly affected physical activity. The levels of physical activity significantly differed by sociodemographic factors, health-related factors, and psychological health-related factors. There was also a difference in the physical activity levels according to the age and sex per each domain of physical activity.

ABSTRACT

Among lesions in the larynx, laryngeal contact granuloma due to persistent tissue irritation can typically be attributed to endotracheal intubation, vocal abuse, or gastro-esophageal reflux disease. Treatment typically includes voice therapy, lifestyle changes and use of anti-reflux medication. Microsurgical removal is only indicated in cases of severe dyspnea due to mass size. Foreign body granuloma is a response of to any foreign material in the tissue. Foreign body granulomas are sometimes misdiagnosed as soft tissue tumors when the causative foreign body is not initially found. Delayed treatment of these foreign bodies may cause complications. We present a case of larynx granuloma due to impacted foreign body, probably fish bone, in the larynx that mimicked contact granuloma. We initially used anti-reflux medication, but to no avail. The laryngeal mass, observed through laryngoscopy, showed no improvement and therefore necessitated a proper pathologic diagnosis. We were able to successfully treat it via trans-oral laser CO2 microsurgery before any complications developed.

ABSTRACT

Background and Objectives@#OperaVOXTM (Oxford Wave Research Ltd.) is a portable voice analysis software package designed for use with iOS devices. As a relatively cheap, portable and easily accessible form of acoustic analysis, OperaVOXTM may be more clinically useful than laboratory-based software in many situations. The aim of this study was to evaluate the agreement between OperaVOXTM and Multi-Dimensional Voice Program (MDVP; Computerized Speech Lab) to assess voice quality before and after laryngeal microsurgery in patient with vocal polyp.Materials and Method Twenty patients who had undergone laryngeal microsurgery for vocal polyp were enrolled in this study. Preoperative and postoperative voices were assessed by acoustic analysis using MDVP and OperaVOXTM. A five-seconds recording of vowel /a/ was used to measure fundamental frequency (F0), jitter, shimmer and noise-to-harmonic ratio (NHR). @*Results@#Several acoustic parameters of MDVP and OperaVOXTM related to short-term variability showed significant improvement. While pre-operative value of F0, jitter, shimmer, NHR was 155.75 Hz (male: 125.37 Hz, female: 183.37 Hz), 2.20%, 6.28%, 0.16, post-operative values of these parameter was 164.34 Hz (male: 129.42 Hz, female: 199.26 Hz), 2.15%, 5.18%, 0.14 Hz in MDVP. While pre-operative value of F0, jitter, shimmer, NHR was 168.26 Hz (male: 135.16 Hz, female: 201.37 Hz), 2.27%, 6.95%, 0.26, post-operative values of these parameters was 162.72 Hz (male: 128.267 Hz, female: 197.18 Hz), 1.71%, 5.36%, 0.20 in OperaVOXTM. There was high intersoftware agreement for F0, jitter, shimmer with intraclass correlation coefficient. @*Conclusion@#Our results showed that the short-term variability of acoustic parameters in both MDVP and OperaVOXTM were useful for the objective assessment of voice quality in patients who received laryngeal microsurgery. OperaVOXTM is comparable to MDVP and has high intersoftware reliability with MDVP in measuring the F0, jitter, and shimmer.

ABSTRACT

Background and Objectives@#Transoral laser microsurgery (TLM) is minimally invasive and has become the standard approach for early and intermediate stage laryngeal cancers. Many studies show that the oncologic results of TLM are equivalent to those obtained by conventional conservative surgery and radiotherapy (RT). The purpose of this study were to analyze the treatment outcome and predictors of local recurrence in glottic cancer patients who underwent TLM.Subjects and Method Sixty-seven patients who received TLM for glottis cancer between 2008 and 2019 were analyzed retrospectively. Patients were predominantly male (98.5%), with a median age of 64.3 years (range 45 to 87 years). There were 35 cases of T1 (52.2%), 15 cases of T2 (22.3%), and 17 cases of T3 (25.3%) in the primary tumor stage. There were no patients with lymph node metastasis (cN0). When classified into types, there were 2 cases of type I (3%), 15 cases of type II (22.3%), 34 cases of type III (50.7%), 4 cases of type IV (5.9%), 12 cases of type V (17.9%). The local control rate and overall survival rate were calculated with KaplanMeier curve analysis. Additionally, multivariate analysis of factors associated with local recurrence used Cox proportional-hazards model. @*Results@#TLM alone was performed in 54 patients (80.5%) whereas 13 patients (19.5%) underwent TLM followed by adjuvant RT. The 5-year local control rate and 5-year overall survival rate were 81.9% and 93.3%, respectively. In the Univariate analysis, the significant factors of local recurrence were difficult laryngeal exposure [odds ratio (OR)=22.8, 95% confidence interval (CI)=1.7-297.4, p-value=0.03], anterior commissure invasion (OR=17.2, 95% CI=1.9-154.7, p-value=0.004, positive lymphovascular invasion (OR=18.0, 95% CI=2.9-109.8, p-value=0.003) and positive resection margin (OR=9.5, 95% CI=1.6-55.6, p-value=0.011). In the multivariate analysis, the independent factors of local recurrence were anterior commissure invasion [hazard ratio (HR)=18.4, 95% CI=1.98-170.99, p-value=0.010] and lymphovascular invasion (HR=7.5, 95% CI=1.49-38.15, p-value=0.015). No major or lethal complications were observed. @*Conclusion@#TLM is a reliable modality to treat early and select cases of moderately advanced glottic cancer. Our study found that independent factors of local recurrence included anterior commissure invasion, and lymphovascular invasion. These findings may be useful to follow-up glottic cancer patients after TLM.

ABSTRACT

Background and Objectives@#Vocal polyps are generally caused by phonotrauma such as vocal overuse, and the first line treatment is known as laryngeal microsurgery. The aim of the study is to evaluate the applicability and effectiveness of percutaneous steroid injection via cricothyroid membrane in patients with vocal polyp and to evaluate its advantages and limitations of the technique.Subjects and Method We included in this study 70 patients with vocal polyp managed by vocal fold steroid injection via the cricothyroid membrane from Jan 2008 to July 2018. We compared their medical records of laryngoscopy, stroboscopy, and multi-dimensional voice program analysis at pre and post treatment. Subjective voice improvement was evaluated using Voice Handicap Index-30 (VHI-30). @*Results@#Of the patients, 54.3 percent showed morphological improvement. In acoustic analysis, the pre-treatment mean values of jitter, shimmer, and NHR were 2.20±2.23, 5.09±3.24, 0.15±0.04, respectively. The post-treatment values were 1.54±1.28, 5.00±4.40, 0.13±0.04, respectively, and only jitter was statistically significant. For subjective symptom improvement, 32 (45.8%) patients showed better score on the post-treatment of VHI-30 compared to pretreatment. Ten patients experienced mild complications such as vocal fold atrophy and scar; however, no critical complications such as internal bleeding or dyspnea were reported. @*Conclusion@#According to our study, steroid injection is a safe and effective procedure for patients with vocal polyp. A vocal fold steroid injection via the cricothyroid membrane can be an alternative treatment option for those who are not able to undergo conventional laryngeal microscopic surgery.

ABSTRACT

BACKGROUND AND OBJECTIVES@#Reinke's edema is a benign vocal fold disease caused by an edematous laryngeal superficial layer of lamina propria. The first line treatment is cessation of smoking and laryngeal microsurgery. The aim of the study is to evaluate the feasibility and efficacy of percutaneous steroid injection via cricothyroid membrane in patients with Reinke's edema.MATERIALS AND METHOD: From Jan 2010 to July 2018, 33 Patients with Reinke's edema managed by vocal fold steroid injection via the cricothyroid membrane were included in this study. We compared medical records of laryngoscopy, stroboscopy and Multi-Dimensional Voice Program analysis at pre-treatment and post-treatment. Subjective voice improvement was evaluated using Voice Handicap Index-30 (VHI-30).@*RESULTS@#75.7% of the patients showed partial response and 6.06% showed complete response. 93.94% were present smokers and only 4 patients ceased smoking after the treatment. In acoustic analysis, the pre-treatment mean value of jitter, shimmer, and noise to harmonic ratio was 2.30±3.21, 9.34±10.37, 1.11±2.90 each. The post-treatment value was 2.20±1.89, 6.96±5.30, 0.20±0.09 respectively and none of the parameters were statistically significant. For subjective symptom improvement, 25 (75.8%) patients showed a better score on post-treatment VHI-30 compared to pre-treatment.@*CONCLUSION@#According to our study, steroid injection is a relatively safe and effective procedure for patients with Reinke's edema. A vocal fold steroid injection via the cricothyroid membrane can be an alternative treatment option for those who are not able to undergo conventional laryngeal microscopic surgery, however cessation of smoking is necessary for effective treatment.

ABSTRACT

Intravenous pyogenic granuloma (IVPG), also known as intravenous lobular capillary hemangioma, is an extremely rare form of vascular tumor which derives from the lumen of a vein of the head and neck and upper extremities. The treatment of choice is complete local excision of a small portion of the vein. Since first report in 1979, IVPG has been reported in no more than 60 reports abroad. To our knowledge, IVPG originating in the external jugular vein has never been reported in Korea but has important clinical implication. Accurate preoperative diagnosis of neck mass originating in jugular vein is important to plan operative procedures to avoid vascular injury, excessive bleeding, or incomplete excision. Preoperative radiologic examinations such as ultrasonography, computed tomography are useful as first-line diagnostic tools for differential diagnosis of movable neck mass. With a review of literature, the author reports a case of IVPG arising from the left external jugular vein in a 31-year-old male who complained about a palpable neck mass. This patient was successfully managed by ligation and excision of the vein without any complication and no recurrence was found after 6 months.

ABSTRACT

BACKGROUND/AIMS: Epidemiologic and clinical data indicate that allergies may be associated with reduced risks for several cancers; however, to date, only a few studies have examined the associations between allergies and gastric cancer. This study aimed to examine the associations between allergies and gastric cancer using a large population-based dataset. METHODS: This cross-sectional study obtained data from the Korea National Health and Nutrition Examination Survey between 2010 and 2014, involving a total of 24,089 participants. The associations between allergies and gastric cancer were analyzed using univariable and multivariable logistic regression analyses with complex sampling, while adjusting for confounding factors that included age, sex, body mass index, smoking status, alcohol intake, and level of education. RESULTS: Multivariable logistic regression analyses that were adjusted for the potential confounders determined that a history of allergic diseases tended to be associated with reduced risk of gastric cancer; however, this relationship was not statistically significant (any allergy: odds ratio [OR], 0.62; 95% confidence interval [CI], 0.34-1.12; atopic dermatitis: OR, 0.34; 95% CI, 0.50-1.72; allergic rhinitis: OR, 0.71; 95% CI, 0.34-1.46; asthma: OR, 0.44; 95% CI, 0.15-1.29). Multivariable analysis showed that a history of atopic dermatitis was associated with reduced risk of gastric cancer in men (OR, 0.16; 95% CI, 0.03-0.75). CONCLUSIONS: This findings of this study suggest that individuals with allergies tend to have a reduced risk of gastric cancer, without a statistically significant association. Furthermore, atopic dermatitis was associated with reduced risk of gastric cancer, particularly in men.

ABSTRACT

The purpose of the present study was to determine the potential relationships of glycemic control and use of metformin with non-muscle invasive bladder cancer characteristics. We reviewed data from 645 patients with non-muscle invasive bladder cancer between January 2004 and May 2015. We analyzed the association of pre and post-operative glycemic control and use of metformin with clinical characteristics of bladder tumors. We also analyzed the association of glycemic control and use of metformin with recurrence-free and progression-free survivals. Diabetes mellitus patients showed decreased recurrence-free survival (hazard ratio 1.42; 95% confidence interval 1.1-1.9; P = 0.021) and progression-free survival (hazard ratio 1.79; 95% confidence interval 1.1-2.8; P = 0.013). Diabetes mellitus patients with a HbA1c ≥ 7.0% demonstrated a higher rate of progression (P = 0.026). Kaplan-Meier analysis showed that progression-free survival rate was associated with poor baseline glycemic control (P = 0.026) and post-operative glycemic control (P = 0.025). However, use of metformin had no impact on the recurrence (P = 1.00) and progression (P = 0.282). In conclusion, poor baseline and post-operative glycemic control was related with shorter progression-free survival of patients with non-muscle invasive bladder cancer. Use of metformin had no impact on the recurrence and progression. Therefore, tight glycemic control and close follow-up for bladder tumor may be beneficial in patients with poor glycemic control.

ABSTRACT

IgG4-related disease (IgG4-RD) is a group of fibro-inflammatory diseases affecting multiple organ systems, pathologically characterized by tissue infiltration with abundant IgG4-positive cells. We here report a case of IgG4-RD that was successfully controlled by mycophenolic acid (MPA). A 62-year-old male visited complaining of dizziness and loss of appetite. He had a clinical history of autoimmune pancreatitis treated with steroids and cyclophosphamide 5 years prior, and had also been diagnosed with Hashimoto's thyroiditis at the age of 55 years. We initially prescribed prednisolone (1 mg/kg), tapered to 5 mg/day over 8 months. However, his eosinophilia gradually deteriorated, and we added cyclophosphamide (1 mg/kg daily) for the next 7 months. His laboratory data fluctuated when he was on low-dose predinisolone and cyclophosphamide, and we thus changed his medication to prednisolone combined with MPA for the following 63 months. Currently, his laboratory findings are stable.

ABSTRACT

Craniopharyngiomas are rare primary intracranial tumors. Despite their benign histological appearance, they are often associated with an unfavorable prognosis. The typical manifestations upon diagnosis are headache, visual impairment, polyuria/polydypsia, growth retardation, disturbance of pubertal development, and significant weight gain. The treatment options include radical surgery or radiotherapy, or a combination of these modalities. Slipped capital femoral epiphysis (SCFE) is the most common adolescent hip disorder. SCFE occurs when the capital femoral epiphysis displaces posteriorly on the femoral neck at the level of the physis. The etiology of SCFE is thought to be multifactorial and may include obesity, growth surges, and less common endocrine disorders. The related endocrine disorders include hypothyroidism, growth hormone supplementation, hypogonadism, and panhypopituitarism.
