    Background: Cervical lymphadenopathy is commonly seen in general practice, and its etiology is diverse. Establishing the diagnostic strategy for lymphadenopathy would be desirable to avoid overlooking neoplasms or other critical conditions. This study aims to identify the useful laboratory parameters for cervical lymphadenopathy that require clinical observation or intervention. Methods: The participants were outpatients presenting cervical swelling or cervical lymph node (LN) pain who consulted the General Internal Medicine department from 2010 to 2016. We evaluated the characteristics, physical findings, and laboratory parameters with final diagnoses by multivariate logistic regression analysis. We categorized the final diagnoses as "Clinical Intervention Required Group (CIRG)" including necrotizing lymphadenitis, hematologic neoplasms, metastatic lymphadenopathy, tuberculous lymphadenitis, bacterial infectious diseases, infectious mononucleosis, autoimmune diseases, and other abnormal conditions or "No-CIRG" not requiring further clinical observation or intervention. Results: We evaluated 409 participants, with 130 (31.8%) diagnosed as belonging to the CIRG. There was an association between CIRG and various parameters: age ≥60 years old (adjusted odds ratio [AOR], 2.70; 95% confidence interval [CI], 1.48-4.90), having a referral (AOR, 1.83; 95% CI, 1.12-3.00), diameter of LN ≥ 2 cm (AOR, 1.91; 95% CI, 1.05-3.48), fixed LNs (AOR, 2.74; 95% CI, 1.02-7.37), and lactate dehydrogenase (LD) ≥400 U/L (AOR, 3.78; 95% CI, 1.46-9.77). Eighty-two percent of LD ≥ 400 cases in the CIRG were infectious mononucleosis or necrotizing lymphadenitis. Conclusions: Besides the clinical indicators reported previously, we may apply an elevated LD level as a useful indicator of cervical lymphadenopathy that requires further clinical observation or intervention.

    Background: Subjects with prehypertension (pre-HT; 120/80 to 139/89 mm Hg) have an increased risk of cardiovascular disease (CVD); however, whether the risk of pre-HT can be seen at the pre-HT status or only after progression to a hypertensive (HT; >= 140/90 mm Hg) state during the follow-up period is unknown. Methods: The Jichi Medical Cohort study enrolled 12,490 subjects recruited from a Japanese general population. Of those, 2227 subjects whose BP data at baseline and at the middle of follow-up and tracking of CVD events were available (median follow-up period: 11.8 years). We evaluated the risk of HT in those with normal BP or pre-HT at baseline whose BP progressed to HT at the middle of follow-up compared with those whose BP remained at normal or pre-HT levels. Results: Among the 707 normotensive patients at baseline, 34.1% and 6.6% of subjects progressed to preHT and HT, respectively, by the middle of follow-up. Among 702 subjects with pre-HT at baseline, 26.1% progressed to HT. During the follow-up period, there were 11 CVD events in normotensive patients and 16 CVD events in pre-HT patients at baseline. The subjects who progressed from pre-HT to HT had 2.95 times higher risk of CVD than those who remained at normal BP or pre-HT in a multivariable-adjusted Cox hazard model. Conclusion: This relatively long-term prospective cohort study indicated that the CVD risk with pre-HT might increase after progression to HT; however, the number of CVD events was small. Therefore, the results need to be confirmed in a larger cohort. (C) 2016 The Authors. Publishing services by Elsevier B.V. on behalf of The Japan Epidemiological Association.

    目的 : 当学には, 卒後9年間就業を継続するという前提がある. 今回, 当学女子医学生に求められている卒前教育プログラムを調査するため, ワークライフバランスに関するニーズ分析を行った.方法 : 全女子在校生187人に自記式調査を依頼した.結果 : 回答者104人のうち, 義務年限内に結婚・出産を希望した者はそれぞれ71%, 68.6%であった. 80.0%が「出産」に対して, 78.1%が「家庭との両立」に対して不安が高いと回答した. 回答者の8割以上が希望したプログラムは「卒業生女性医師の経験談」「卒業生女性医師との懇談会」「女性医師支援制度についての情報提供」「キャリアアップについての情報提供」であった.結論 : 当学女子医学生の不安は大きいが, 地域医療に貢献する卒業生女性医師との交流を生かしたプログラムを受けられるメリットがある. 当学の卒前教育において, ロールモデルの存在を明確にすることが求められていると考えられた.

    Purpose: General practitioners have an important role in diagnosing a variety of patients, including psychiatric patients with complicated symptoms. We evaluated the relationship between physical symptoms and psychiatric disorders in general internal medicine (GIM) outpatients in a Japanese university hospital. Materials and methods: We coded the symptoms and diagnoses of outpatients from medical documents using the International Classification of Primary Care, second edition (ICPC-2). The participants were new outpatients who consulted the GIM outpatient division at Jichi Medical University Hospital in Tochigi, Japan from January–June, 2012. We reviewed all medical documents and noted symptoms and diagnoses. These were coded using ICPC-2. Results: A total of 1,194 participants were evaluated, 148 (12.4%) of whom were diagnosed as having psychiatric disorders. The prevalence of depression, anxiety disorder, and somatization was 19.6% (number [n] =29), 14.9% (n=22), and 14.2% (n=21), respectively, among the participants with psychiatric disorders. The presence of several particular symptoms was associated with having a psychiatric disorder as compared with the absence of these symptoms after adjusting for sex, age, and the presence of multiple symptoms (odds ratio [OR] =4.98 [95% confidence interval {CI}: 1.66–14.89] for palpitation OR =4.36 [95% CI: 2.05–9.39] for dyspnea OR =3.46 [95% CI: 1.43–8.36] for tiredness and OR =2.99 [95% CI: 1.75–5.13] for headache). Conclusion: Not only the psychiatric symptoms, but also some physical symptoms, were associated with psychiatric disorders in GIM outpatients at our university hospital. These results may be of help to general practitioners in appropriately approaching and managing patients with psychiatric disorders.

    Background Prehypertension is associated with an increased risk of the development of hypertension and subsequent cardiovascular disease. However, it is unclear whether the increased risk of cardiovascular disease associated with prehypertension varies by duration of follow-up (i.e., the first 5 years vs. second 5 years) or varies between nonelderly and elderly individuals. Methods We enrolled 11 000 community dwelling persons (6739 women and 4261 men, aged 18-90 years) from the Japanese general population, followed them for an average of 10.7 +/- 2.4 years (117 517 person-years) and evaluated the incidence of cardiovascular events (including both stroke and myocardial infarction). Results In the full cohort, prehypertension was associated with a 45% higher risk of cardiovascular events than normal blood pressure after adjusting for traditional cardiovascular risk factors (hazard ratio = 1.45, P = 0.03). The risk of cardiovascular events with prehypertension during the second 5-year period was elevated in the nonelderly subgroup (<65 years) (hazard ratio = 2.13, P = 0.01), but not in the elderly subgroup (>= 65 years) (hazard ratio = 0.93, P = 0.82) (P = 0.054 for the difference in hazard ratio). The elevated risk with prehypertension during the first 5-year period was not significant in either the nonelderly (hazard ratio = 1.60, P = 0.36) or elderly (hazard ratio = 1.19, P = 0.63) group. However, the risks with prehypertension were not statistically different between the first and second 5-year period. Conclusion Prehypertension is associated with an increased 10-year risk of cardiovascular disease; the provocative finding that this risk may be especially elevated during the second 5-year period in the nonelderly requires confirmation in a larger cohort.
