Simple drainage versus drainage with minocycline infusion for symptomatic hepatic cysts.

Percutaneous treatment of symptomatic hepatic cysts includes simple drainage and drainage with sclerosing agents. We compared the efficacy of simple drainage with that of drainage with minocycline infusion for treating symptomatic hepatic cysts. We retrospectively evaluated 11 patients who underwent percutaneous drainage of symptomatic hepatic cysts. In seven cases, minocycline infusion was added at the discretion of the clinician. Cyst volume was evaluated before drainage, immediately after drainage, and after long-term follow-up. Cyst volume was calculated before treatment by multiplying the orthogonal diameters using the ellipsoid formula. Relapse was defined as the regrowth of the cyst with symptoms. Cyst volume immediately after drainage and after long-term follow-up was significantly less than that before treatment for the drainage with minocycline infusion group (p<0.05) but not for the simple drainage group. The relapse rates were 25% (1/4) for the simple drainage group and 0% for the drainage with minocycline infusion group. Drainage with minocycline infusion could be a promising option for treating symptomatic hepatic cysts, although simple drainage was not reliable.

Evaluation of the visibility of bleeding points using red dichromatic imaging in endoscopic hemostasis for acute GI bleeding (with video).

BACKGROUND AND AIMS: We aimed to clarify whether red dichromatic imaging (RDI), a new type of image-enhanced endoscopy, improves the visibility of bleeding points in acute GI bleeding (AGIB) compared with white-light imaging (WLI). METHODS: Images and videos of bleeding points acquired with WLI and RDI during endoscopic hemostasis for AGIB were retrospectively compared. In images, the color difference between bleeding points and surrounding blood was analyzed. In videos, 4 expert and 4 trainee endoscopists evaluated the visibility on a scale of 1 (undetectable) to 4 (easily detectable). Furthermore, the correlation between the color difference and visibility score was evaluated. RESULTS: We analyzed 64 lesions. The color difference was significantly higher in RDI (13.11 ± 4.02) than in WLI (7.38 ± 3.68, P < .001). The mean visibility score for all endoscopists was significantly higher in RDI (3.12 ± .51) compared with WLI (2.72 ± .50, P < .001); this was also observed in experts (3.18 ± .51 vs 2.79 ± .54, P < .001) and trainees (3.05 ± .54 vs 2.64 ± .47, P < .001). The color difference and visibility score were moderately correlated for all endoscopists (γ = .56, P < .001) and for experts (γ = .53, P < .001) and trainees (γ = .57, P < .001). CONCLUSIONS: RDI improves the visibility of bleeding points in AGIB compared with WLI. RDI can help endoscopists at all levels of experience to recognize bleeding points by enhancing the color contrast relative to surrounding blood.

Pathogenic variants in the survival of motor neurons complex gene GEMIN5 cause cerebellar atrophy.

Cerebellar ataxia is a genetically heterogeneous disorder. GEMIN5 encoding an RNA-binding protein of the survival of motor neuron complex, is essential for small nuclear ribonucleoprotein biogenesis, and it was recently reported that biallelic loss-of-function variants cause neurodevelopmental delay, hypotonia, and cerebellar ataxia. Here, whole-exome analysis revealed compound heterozygous GEMIN5 variants in two individuals from our cohort of 162 patients with cerebellar atrophy/hypoplasia. Three novel truncating variants and one previously reported missense variant were identified: c.2196dupA, p.(Arg733Thrfs*6) and c.1831G > A, p.(Val611Met) in individual 1, and c.3913delG, p.(Ala1305Leufs*14) and c.4496dupA, p.(Tyr1499*) in individual 2. Western blotting analysis using lymphoblastoid cell lines derived from both affected individuals showed significantly reduced levels of GEMIN5 protein. Zebrafish model for null variants p.(Arg733Thrfs*6) and p.(Ala1305Leufs*14) exhibited complete lethality at 2 weeks and recapitulated a distinct dysplastic phenotype. The phenotypes of affected individuals and the zebrafish mutant models strongly suggest that biallelic loss-of-function variants in GEMIN5 cause cerebellar atrophy/hypoplasia.

Clinicopathological Characteristics and Survival Outcomes of Patients with Buccal Squamous Cell Carcinoma: Results of a Multi-Institutional Study.

Background and Objectives: To investigate clinicopathological characteristics and survival outcomes of patients with buccal cancer in Japan. Materials and Methods: This study was conducted using a database of 1055 patients with oral cancers treated between 2010 and 2017 at 12 institutions in Japan. Ninety-two patients (8.7%) with primary buccal cancer were extracted and clinicopathological characteristics and survival outcomes were compared between patients with buccal cancers and patients with other oral cancers. Results: Ages were significantly higher in the patients with buccal cancer (73 years old vs. 69 years old). Buccal cancer had less advanced cT stage and cN stage than other oral cancers. Overall 5-year survival (OS) was 80.6%, and recurrence-free 5-year survival (RFS) of buccal cancers was 67.8%, and there were no significant differences in survival compared with other oral cancers in terms OS or RFS (5y-OS: 82.5%, 5y-RFS: 74.4%). However, patients with stage IV buccal cancer showed poorer prognosis in terms of OS and RFS compared with the same stage patients with other oral cancer. Advanced T stage was the only factor independently associated with both OS and RFS of patients with buccal cancer in this study. Conclusions: Postoperative radiotherapy or chemoradiotherapy should be considered to improve survival outcome of buccal cancer patients, especially for the patients with advanced primary site disease or a higher cancer stage.

Lingual Lymph Node Metastases as a Prognostic Factor in Oral Squamous Cell Carcinoma-A Retrospective Multicenter Study.

Backgrounds and Objectives: The epidemiology and prognostic role of lingual lymph node (LLN) metastasis in patients with oral squamous cell carcinoma (OSCC) remain unclear. Here, we aimed to analyze the clinicopathological features, risk factors, and prognostic role of LLN metastasis in patients with OSCC. Materials and Methods: In total, 945 patients with OSCC were retrospectively analyzed. Clinicopathological features were compared between patients with and without LLN metastasis. The risk factors of LLN metastasis and its effects on survival outcomes were evaluated using multi-variate analysis. Results: LLN metastasis was noted in 67 patients (7.1%). Habitual alcohol consumption and clinical neck node metastasis were independent risk factors for LLN metastasis. LLN metastasis was an independent prognostic factor for disease-free and overall survival, although LLN dissection did not improve survival outcomes. Conclusion: LLN metastasis is an independent adverse prognostic factor. Further prospective studies are needed to fully assess the extent of LLN dissection required in OSCC patients.

Co-Phenotype of Left Ventricular Non-Compaction Cardiomyopathy and Atypical Catecholaminergic Polymorphic Ventricular Tachycardia in Association With R169Q, a Ryanodine Receptor Type 2 Missense Mutation.

BACKGROUND: Left ventricular non-compaction (LVNC) is a cardiomyopathy characterized by prominent trabeculae and intertrabecular recesses. We present the cases of 3 girls with the sameryanodine receptor type 2(RYR2) mutation who had phenotypes of both catecholaminergic polymorphic ventricular tachycardia (CPVT) and LVNC .Methods and Results:Clinical characteristics and genetic background of the 3 patients were analyzed retrospectively. Age at onset was 5, 6, and 7 years, respectively. Clinical presentation included syncope during exercise in all 3 patients and cardiac arrest in 2 patients. LVNC diagnosis was confirmed on echocardiography according to previously defined criteria. Exercise stress testing provoked ventricular arrhythmia in two of the patients. Beta-blockers (n=3) and flecainide (n=2) were given, and an implantable cardioverter defibrillator was used in 1 patient. Genotyping identified the sameRYR2-R169Q missense mutation and no other CPVT- or LVNC-related gene mutations. Functional analysis of the mutation using HEK293 cells with single-cell Ca2+imaging and [3H]ryanodine binding analysis, indicated a gain of function: a reduced threshold for overload-induced Ca2+release from the sarcoplasmic reticulum and increased fractional Ca2+release. CONCLUSIONS: The rare association of LVNC and CPVT phenotypes withRYR2mutations is less likely to be coincidental. Screening for life-threatening arrhythmias using exercise or pharmacologic stress tests is recommended in LVNC patients to prevent sudden cardiac death in those with preserved LV function.

Neck Dissection for Cervical Lymph Node Metastases from Remote Primary Malignancies.

Background and Objectives: Patients with cervical lymph node metastases from remote primary tumours have poor prognoses because of the advanced stage of their cancer. Owing to recent progress in the nonsurgical management of various cancer types, options for surgical treatment to reduce tumour volume are increasing, and may help improve survival rates. For example, neck dissection may be a good option as a definitive therapy for some patients with resectable cervical metastases. We assessed patients who underwent neck dissection with curative intent and discuss the effectiveness of this approach for cervical metastases from remote malignancies. Material and Methods: We retrospectively reviewed the data of 18 patients (10 males and 8 females in an age range of 30-79 years) who underwent neck dissections for neck lymph node metastases from a remote primary tumour between 2010 and 2019. Patient clinical characteristics, preoperative accuracy of positive node localisation using fluorodeoxyglucose positron emission tomography-computed tomography (FDG/PET-CT), and patient survival rates were estimated. Results: Primary sites included ten lungs, two mammary glands, one thymus, one thoracic oesophagus, one stomach, one uterine cervix, one ovary, and one testis per patient. There were 19 levels with FDG/PET-CT positive nodes in 17 out of 18 patients. Conversely, there were 28 pathological positive levels out of 50 dissected levels. The sensitivity, specificity, positive and negative predictive values, and accuracy of FDG-PET/CT in predicting positive nodes were 69%, 88%, 95%, 47%, and 74%, respectively. The three-year overall survival (OS) rate for all patients was 70%. The three-year OS rate of the group with zero or one pathological positive nodes was 81%, which was significantly higher than that of the group with more than two positive nodes (51%) (p = 0.03). Conclusions: Neck dissection for cervical lymph node metastases from remote primary malignancies may improve prognoses, especially considering anticancer agents and radiotherapy advancements.

Colonic diverticular bleeding and predictors of the length of hospitalization: An observational study.

BACKGROUND AND AIM: A significant percentage of patients with colonic diverticular bleeding (CDB) experience bleeding that is severe enough to necessitate prolonged hospitalization. Prolonged hospitalization causes deterioration in patients' quality of life, as well as difficulties with cost-effective utilization of medical resources, and is a financial burden to the society. Therefore, we investigated the factors associated with the length of hospitalization for the optimal management of patients hospitalized with CDB. METHODS: This study included patients who were hospitalized for the treatment of CDB and underwent colonoscopy between July 2008 and February 2016. Logistic regression analysis was performed to investigate the association between the length of hospitalization and the patients' baseline characteristics, in-hospital procedures performed, and the clinical outcomes. RESULTS: The study included 223 patients. Diabetes mellitus (odds ratio [OR] 3.4, P = 0.014) and blood transfusion (OR 3.1, P = 0.0006) were identified as risk factors for prolonged hospitalization (≥ 8 days). Urgent colonoscopy (OR 0.41, P = 0.0072) predicted a shorter length of hospitalization (≤ 7 days). The study also indicated that endoscopic treatment showed a stronger association with urgent colonoscopy (OR 7.8, P < 0.0001) than with elective colonoscopy and that urgent colonoscopy was not associated with an increased rate of adverse events or re-bleeding. CONCLUSIONS: Compared with elective colonoscopy, urgent colonoscopy shortens the length of hospitalization in patients with CDB. Moreover, it is not associated with an increased rate of adverse events. Urgent colonoscopy may be impracticable in a few cases; however, if possible, aggressive urgent colonoscopy should be considered for the efficient management of the patient's hospital stay.

Impaired activity of daily living is a risk factor for high medical cost in patients of non-variceal upper gastrointestinal bleeding.

BACKGROUND: Non-variceal upper gastrointestinal bleeding (NVUGIB) is still a common and life-threatening disease, thus it would have a big impact on medical care cost. However, little is known about risk factors for increased medical care cost in NVUGIB patients. AIM: The purpose of the study was to clarify predictor of requiring high medical care cost in NVUGIB patients. Patients who underwent endoscopic hemostasis due to NVUGIB between April 2012 and March 2015 were included in this retrospective study. We analyzed the association between patients' background including activity of daily livings (ADL) and high medical care cost using logistic regression model. Medical care cost was calculated in reference to the "Diagnosis Procedure Combination" which is diagnosis-dominant case-mix system in Japan. The cutoff value of high medical care cost was defined as its first quartile. ADL was assessed according to Katz-6 score. We defined impaired ADL patient who revealed Katz-6 score more than 1. RESULTS: A total of 128 consecutive patients were included in this study. Median medical care cost was 5323 USD (IQR 3661-8172 USD). There were 13 patients (10%) in impaired ADL group. In univariate analysis, age and impaired ADL before admission revealed significant association with high cost. Of these, impaired ADL was an only independent risk factor [odds ratio 15.3 (95% CI 2.49-183)] in multivariate analysis. CONCLUSION: Impairment in ADL before admission was an independent predictor for high medical care cost with NVUGIB patients.

Clinical features of hypermagnesemia in patients with functional constipation taking daily magnesium oxide.

Although magnesium oxide is widely used as a laxative, alterations in serum magnesium concentrations among patients taking daily magnesium oxide have not been clarified. The present retrospective, cross-sectional study investigated the risk factors for hypermagnesemia in patients taking daily oral magnesium oxide. Of 2,176 patients administered daily magnesium oxide, 193 (8.9%) underwent assays of serum magnesium concentrations and were evaluated. High serum magnesium concentration and hypermagnesemia were defined as serum magnesium concentrations ≥2.5 mg/dl and ≥3.0 mg/dl, respectively. Of the 193 patients taking daily magnesium oxide, 32 (16.6%) had high serum magnesium concentration and 10 (5.2%) had hypermagnesemia. Factors associated with hypermagnesemia included chronic kidney disease (CKD) grade 4 (p = 0.014) and magnesium oxide dosage (p = 0.009). Factors associated with high serum magnesium concentration included magnesium oxide dosage >1,000 mg/day (p = 0.004), CKD grades 4 (p = 0.000) and concomitant use of stimulant laxatives (p = 0.035). Age, however, was not associated with hypermagnesemia or high serum magnesium concentration. In conclusion, renal function and magnesium oxide dosage, but not age, were associated with hypermagnesemia and high serum magnesium concentration in patients with functional constipation taking daily magnesium oxide.

Association of a single nucleotide polymorphism in TNIP1 with type-1 autoimmune hepatitis in the Japanese population.

Several studies reported that autoimmune diseases share a number of susceptibility genes. Of these genes, a SNP rs7708392 in TNIP1 was reported to be associated with systemic lupus erythematosus (SLE). Autoimmune hepatitis (AIH), a rare chronic progressive liver disease, shares some clinical features with SLE. Therefore, we investigated whether the SNP is associated with Japanese AIH. An association study of rs7708392 was conducted in 343 Japanese AIH patients and 828 controls. We found that rs7708392 is associated with AIH (P = 0.0236, odds ratio (OR) 1.26, 95% confidence interval (CI): 1.03-1.54), under the allele model for C allele. Significant differences of clinical characteristics of the AIH patients with or without G allele of rs7708392 were not detected. Of interest, the association was stronger in AIH without HLA-DRB1*04:05 allele (P = 0.0063, Q = 0.0127, OR 1.48, 95% CI: 1.12-1.96), though the association was not detected in AIH with DRB1*04:05. The C allele of rs7708392 was associated with AIH, especially AIH without DRB1*04:05, an already established risk factor.

The Role of History of Gastro-Duodenal Ulcer in Patients with Upper Gastrointestinal Bleeding.

BACKGROUND: Some scoring systems have been introduced to predict the need for performing urgent endoscopy in patients with upper gastrointestinal bleeding (UGIB). However, in an emergency situation, this intervention is insufficient and cannot easily provide the required treatment. AIM: To identify new risk factors that can predict the need for endoscopic intervention (EI) in UGIB patients. METHODS: This is a retrospective cross-sectional study. Patients with UGIB admitted from April 2011 to August 2014 were included. The proportion of cases requiring EI and clinical factors (age, gender, antiplatelet/anticoagulant therapy, history of gastro-duodenal ulcer (GDU), systolic blood pressure, heart rate, hemoglobin, mean corpuscular volume, blood urea nitrogen-creatinine ratio (BUN/Cr ratio), prothrombin time-international normalized ratio, and Glasgow-Blatchford Score (GBS) were analyzed using logistic regression models. RESULT: Of 378 patients who were included in this study, 180 were found to be with GDU. The proportion of cases requiring EI was significantly higher in those with GDU than in other causes except variceal bleeding (53.5 vs. 37.0%, p < 0.01). Multivariate analysis revealed that a history of GDU was an independent risk factor (OR 1.78, 95% CI 1.06-3.00) in addition to BUN/Cr ratio (OR 1.02, 95% CI 1.00-1.03) and GBS (OR 1.19, 95% CI 1.08-1.33). CONCLUSION: A history of GDU was an independent risk factor for predicting the need for EI in UGIB in addition to BUN/Cr ratio and GBS.

Risk Factor for Vital Signs Fluctuation during Colonoscopy under Conscious Sedation Consisting of Midazolam and Meperidine.

BACKGROUND: Sedatives or analgesics are widely used to relieve a patient's discomfort during colonoscopy (CS). Although cardiopulmonary adverse events are sometimes experienced during the examination, the risk factors for vital signs fluctuation (VSF) have not been fully elucidated. This study thus aimed to identify the risk factors for VSF during the examination, as well as to evaluate the frequency and the degree of VSF. SUMMARY: A total of 755 consecutive subjects who received CS under endoscopist-administrated sedation using midazolam, meperidine, or combination of both were retrospectively analyzed. We assessed the distribution of vital signs during the procedure and frequency of VSF. To identify independent risk factors, we analyzed the association between VSF and subjects' characteristics and procedure information using the multivariate logistic regression model. Consequently, VSF was observed in 17% of all; hypotension and oxygen desaturation was observed in 13 and 5%, respectively. However, we could achieve the purpose of all procedure and, no one required hospitalization or extension of hospital stay. Multivariate analysis revealed that age (OR 1.05 [95% CI 1.04-1.07]), being female (OR 1.78 [95% CI 1.19-2.70]), and use of midazolam (OR 5.06 [95% CI 3.18-8.08]) were independent risk factors for VSF.

Prognostic impact of incisional or excisional biopsy of cervical lymph node metastases of solid tumors.

OBJECTIVES: In performing an open biopsy of a neck mass, an incisional biopsy may increase the risk of cancer cell seeding and dissemination that, ultimately, worsens a patient's survival. The aim of this study was to compare the impact of incisional and excisional biopsies of cervical lymph node metastases of solid tumors on patients' survival. METHODS: A retrospective review was made of patients with cervical metastases of solid tumors who underwent an open biopsy for a diagnosis between 2005 and 2015. Sixty-four patients met the criteria out of 524 open biopsy cases undertaken during the period. Survival analyses were estimated from 33 cases whose initial symptoms were the presence of a neck mass, using two modes of biopsy: excisional and incisional. RESULTS: The 2-year overall survival rates in incisional and excisional biopsy groups were 65% and 43%, respectively, and 2-year disease-specific survival rates were 74% and 43%, respectively. The differences were not significant. For lung cancer or head and neck cancer subgroups, survival differences between incisional and excisional biopsy groups were also not significant. CONCLUSIONS: A carefully targeted physical examination and performing a fine needle aspiration are essential to establish a diagnosis for the etiology of an unknown neck mass. In performing an open biopsy, the effect of an incisional biopsy on patients' survival was no worse than that of an excisional biopsy, despite the latter being theoretically preferable.

Usefulness of Mean Corpuscular Volume for Detection of Advanced Colorectal Cancer in Patients Older than 85 Years.

BACKGROUND/AIMS: The aim of this study was to elucidate clinical indicators for the detection of advanced colorectal cancer (ACRC). METHODS: This was a retrospective study conducted at a tertiary hospital. This study included 333 patients older than 85 years who underwent colonoscopy from April 2006 to May 2010. The detection rate of ACRC was assessed. Then, we analyzed the association between the detection of ACRC and various background factors including mean corpuscular volume (MCV). We also analyzed the cumulative overall survival of patients with detected ACRC. RESULTS: ACRC was found in 37 patients, resulting in a detection rate of 15%. Multivariate logistic regression analysis revealed that a decreased MCV was an independent predictor for the detection of ACRC (OR 0.88, 95% CI 0.84-0.94), whereas symptoms such as abdominal pain, hematochezia, or anemia were not independent predictors. MCV was an independent predictor irrespective of the location of the tumor. The cumulative survival rates at 3 and 5 years after diagnosis were 78 and 58%, respectively, during a median observational period of 30.3 months. CONCLUSION: This study demonstrated the usefulness of MCV as an indicator of the necessity of colonoscopy for older patients.

Initial Management of Colonic Diverticular Bleeding: Observational Study.

BACKGROUND/AIMS: Although colonic diverticular bleeding (CDB) often ceases spontaneously, re-bleeding occurs in about 30%. Bleeding diverticulum can be treated directly by endoscopic hemostasis; however, it is difficult to perform colonoscopy in all cases with limited medical resource and certain risks. The aim of this study was to clarify who should undergo colonoscopy as well as appropriate methods of initial management in CDB patients. METHODS: A total of 285 patients who were diagnosed as CDB and underwent colonoscopy from March 2004 to October 2015 were retrospectively analyzed. First, the association between re-bleeding and various factors including patients' background and initial management were analyzed. Second, the examination conditions that influenced bleeding point identification were analyzed. RESULTS: Of 285 patients, 187 were men and 98 were women. Median age was 75 years, and the median observation period was 17.5 months. Re-bleeding was observed in 79 patients (28%). A history of CDB (OR 2.1, p = 0.0090) and chronic kidney disease (CKD; OR 2.3, p = 0.035) were risk factors, and bleeding point identification (OR 0.20, p = 0.0037) was a preventive factor for re-bleeding. Bleeding point identification significantly reduced approximately 80% of re-bleeding. Furthermore, extravasation on CT (OR 3.7, p = 0.031) and urgent colonoscopy (OR 5.3, p < 0.001) were predictors for identification of bleeding point. Compared to bleeding point identification of 11% in all patients who underwent colonoscopy, identification rate in those who had extravasation on CT and underwent urgent colonoscopy was as high as 70%. CONCLUSIONS: Contrast-enhanced CT upon arrival is suggested, and patients with extravasation on CT would be good candidates for urgent colonoscopy, as well as patients who have a history of CDB and CKD.

Association of a single nucleotide polymorphism upstream of ICOS with Japanese autoimmune hepatitis type 1.

Autoimmune hepatitis (AIH) is an uncommon chronic autoimmune liver disease. Several studies reported the association of polymorphisms between CD28, CTLA4 and ICOS gene cluster in 2q33.2 with autoimmune or inflammatory diseases. The previous genome-wide association study on type 1 AIH in a European population has reported a risk G allele of a single nucleotide polymorphism (SNP), rs4325730, in this region. Here, we conducted an association study of this SNP with type 1 AIH in a Japanese population, as a replication study.An association study of rs4325730 was conducted in 343 Japanese AIH patients and 315 controls.We found that rs4325730 is associated with AIH (P=0.0173, odds ratio (OR) 1.30, 95% confidence interval (CI) 1.05-1.62, under the allele model for G allele, P=0.0070, OR 1.62, 95% CI 1.14-2.31, under the dominant model for G allele). This SNP was strongly associated with definite AIH (P=0.0134, OR 1.36, 95% CI 1.07-1.74; under allele model for G, P=0.0035, OR 1.85, 95% CI 1.22-2.81, under dominant model for G).This is the first replication association study of rs4325730 upstream of ICOS with AIH in the Japanese population and rs4325730G is a risk allele.

Facial flushing after alcohol intake as a predictor for a high risk of synchronous or metachronous cancer of the upper gastrointestinal tract.

BACKGROUND: In Japan, there has been a lot of reports showing an association between facial flushing after light alcohol consumption and heterozygosity for inactive aldehyde dehydrogenase-2 (ALDH2). Persons with inactive ALDH2 may have a higher risk of alcohol-related oral, pharyngeal and esophageal cancers, compared with those with wild-type ALDH2. The purpose of this study was to examine whether flushers with oral or pharyngeal squamous cell carcinoma have an increased risk of synchronous or metachronous cancer of the upper gastrointestinal (UGI) tract. METHODS: A retrospective study was performed by medical chart review and through a questionnaire sent to 285 patients treated for oral and pharyngeal cancer. Responses were obtained from 150 patients (52.6%), who were classified as flushers or non-flushers, smokers (≥20 pack-year; 1 pack-years = number of cigarettes/20 per day) or non-smokers, and drinkers (≥14 units of alcohol consumption per week; 1 unit = 22 g) or non-drinkers. Relationships of these factors with occurrence of second primary cancers (SPCs) in the UGI tract were investigated. RESULTS: In Kaplan-Meier analysis, there was a significantly higher rate of SPC at 5 years in flushers and drinkers, but no relationship with smoking. In multivariate analyses, a history of flushing was significantly associated with SPC in the UGI tract (HR 2.64, 95% CI 1.25-5.52, P = 0.0109), but not with smoking or alcohol consumption. CONCLUSIONS: A simple interview on history of facial flushing after alcohol intake can be useful for identifying patients at high risk for synchronous or metachronous cancers of the UGI tract.

Musical Instrument-Associated Health Issues and Their Management.

Playing musical instruments can bring joy to people, but can also cause a wide variety of health issues that range from mild disorders to potentially fatal conditions. Although sports medicine is an established medical subspecialty, relatively few studies have investigated the health issues associated with musical instruments. Here we present an overview of these health issues. These include infections due to microorganisms, allergic reactions, as well as mechanical injuries from sustained high pressures within the oral, mediastinal, thoracic, and abdominal cavities. For example, wind instruments can potentially harbor thousands of pathogenic organisms. If several players share the same instrument, these instruments present potential hazards in the spread of infections. A fatal case of hypersensitivity pneumonitis in a bagpiper is particularly noteworthy. Similarly, a case of gastrointestinal anthrax in an animal-hide drummer is a reminder of this rare but highly fatal disease. Although not fatal, hearing-related disorders, neuromuscular issues, musculoskeletal problems, and contact dermatitis are also very common among instrumentalists. This review aims to illuminate these under-recognized health issues by highlighting both the common conditions and the rare but fatal cases.
