BACKGROUND Adrenal incidentaloma (AI) has been frequently encountered in the clinical setting. It has been shown that primary aldosteronism (PA) or subclinical Cushing’s syndrome (SCS) are the representative causative diseases of AI. However, the coexistence of PA and SCS has been reportedly observed. Recently, we encountered a case of AI, in which PA and SCS coexisted, confirmed by histopathological examinations after a laparoscopic adrenalectomy. We believe that there were some clinical implications in the diagnosis of the present case. CASE SUMMARY A 58-year-old man presented with lower right abdominal pain with a blood pressure of 170/100 mmHg. A subsequent computed tomography scan revealed right ureterolithiasis, which was the cause of right abdominal pain, and right AI measuring 22 mm × 25 mm. After the disappearance of right abdominal pain, subsequent endocrinological examinations were performed. Aldosterone-related evaluations, including adrenal venous sampling, revealed the presence of bilateral PA. In addition, several cortisol-related evaluations showed the presence of SCS on the right adrenal adenoma. A laparoscopic right adrenalectomy was then performed. The histopathological examination of the resected right adrenal revealed the presence of a cortisol-producing adenoma, while CYP11B2 immunoreactivity was absent in this adenoma. However, in the adjacent non-neoplastic adrenal, multiple CYP11B2-positive adrenocortical micronodules were detected, showing the presence of aldosterone-producing adrenocortical micronodules. CONCLUSION Careful clinical and pathological examination should be performed when a patient harboring AI presents with concomitant SCS and PA.

Approximately 30% of patients experience nausea after initiation of opioid therapy, which can lead to poor quality of life. We aimed to identify risk factors for opioid-induced nausea at the initiation of opioid therapy by conducting a retrospective review of medical records of patients diagnosed by palliative care specialists with solid cancer and pain at the lesion site at Showa University Hospital between June 2005 and June 2011. The primary endpoint was the development of nausea grade ≥1 according to the Common Terminology Criteria for Adverse Events version 4.0 within 48 hours of initiation of opioid therapy. The median age of the 134 enrolled patients was 67.7 (range 28-95) years. Fifty-three percent were male and 44% had gastrointestinal cancer. Furthermore, 22.4% had opioid-induced nausea. Age (odds ratio (OR) 1.74; 95% confidence interval (CI), 1.13-2.69), edema (OR 5.83; 95% CI, 1.22-28.19), and gastrointestinal cancer (OR 2.61, 95% CI 1.07-6.36) were significantly associated with opioid-induced nausea. Prophylactic antiemetics were found to be ineffective.

Treatment with a combination of norepinephrine and doxazosin was effective in a patient with pheochromocytoma who had blood pressure fluctuation, hypotension, and recurrent syncope. After adrenalectomy, his blood pressure, heart rate, and plasma levels of catecholamines remained normal and stable without any medication. (Level of Difficulty: Beginner.), Graphical abstract, Treatment with a combination of norepinephrine and doxazosin was effective in a patient with pheochromocytoma who had blood pressure fluctuation…

BackgroundSchool urinary screening has been performed in Japan.MethodsIkeda City and Toyono Town introduced, in 2012 and 2013, urinary protein/creatinine (Cr) ratio measurement into the urine-screening protocols designed for students aged between 4 and 15 years. For each student whose urinary protein/Cr ratio was ≥ 0.15 g/gCr (positive case), an appointment was made with a specialist at Ikeda City Hospital. The results of these screening urinalyses conducted through 2018 are summarized.Results14,606 junior high and elementary school students aged between 6 and 15 years were included. On average, they underwent 4.16 screening tests. 77 positive cases were detected, and seven students were diagnosed with high-risk chronic kidney disease (CKD). Of these, four underwent renal biopsy, and two, one, and one were diagnosed with IgA nephropathy, MPGN, and FSGS, respectively. In three students, detection of CKD would have been difficult without urinary screening. Incident rates of high-risk CKD and IgA nephropathy are estimated as 11.5 and 3.3 cases/100,000 students/year. 78.0% of positive cases without high-risk CKD showed no urinary abnormality after one year. 2301 kindergarten students aged between 4 and 6 years received an average of 1.74 screening urinalyses; none was positive or high-risk CKD. The estimated cost of detecting one high-risk CKD student whose detection would have been difficult without this screening was 3,156,711 Japanese yen.ConclusionSchool urinary screening using the urinary protein/Cr ratio can efficiently refer to a specialist. It detects a few children with high-risk CKD early with spending high cost.

Objective: Type 2 diabetes mellitus (T2DM) is associated with a high prevalence of depression, and depression is influenced by personality traits; however, these psychological factors have not been well studied in individuals with T2DM. The association between the use of a 5-factor model of personality and depressive symptoms was examined in individuals with T2DM. Methods: The subjects were 435 T2DM patients (mean age 63.1±12.6 years). Depressive status and personality traits were assessed using the Center for Epidemiologic Studies Depression Scale and the Ten-Item Personality Inventory, Japanese version, respectively. Lifestyle factors and glycated hemoglobin A1c levels in the patients were also included in the analyses. Results: Among the 435 subjects with T2DM, 130 (29.9%) exhibited possible depression, and 68 (15.6%) exhibited probable depression. After adjustment for confounders, Extraversion, Agreeableness and Neuroticism were found to be significantly associated with the presence of depression. No relationships were found between depression and HbA1c. Conclusion: These findings indicate that Extraversion and Agreeableness are protective factors, and Neuroticism is a risk factor for depression in T2DM patients. Psychological therapy focusing on personality may reduce depressive symptoms. Additional studies are needed to examine the relationships between psychological factors and depressive symptoms using a longitudinal study design.

Aims/Introduction Insomnia is associated with type 2 diabetes mellitus, and results in a low quality of life. There are several known relationships between insomnia and personality. Thus, we clarified the association between some personality traits and insomnia among Japanese type 2 diabetes mellitus patients. Materials and Methods The participants were 504 type 2 diabetes mellitus patients (mean age 63.9 ± 12.5 years). Sleep disturbance and personality traits were evaluated using the Pittsburgh Sleep Quality Index‐Japanese version and the Ten‐Item Personality Inventory Japanese version, respectively. Lifestyle factors, glycated hemoglobin levels and depressive status of the patients were also included in the analyses. Results Among the 504 participants with type 2 diabetes mellitus, 154 (30.6%) showed probable insomnia. After adjustment for confounders, being female, living alone, high body mass index and “high neuroticism” were found to be significantly correlated with current insomnia. No other relationships between insomnia and glycated hemoglobin or lifestyle factors, such as smoking, drinking alcohol or exercise frequency, were found. Conclusions The prevalence of insomnia in individuals with type 2 diabetes mellitus was high, and the risk factors included some personality factors. Future prospective studies are required to confirm the therapeutic effects of behavioral interventions for insomnia in patients with type 2 diabetes mellitus.

Congenital generalized lipodystrophy type 4 (CGL4) is a rare disease caused by mutations in the gene polymerase I and transcript release factor (PTRF), the main symptoms of which are systemic reductions in adipose tissue and muscular dystrophy. The strategy of treating CGL4 is to improve the insulin resistance and hypertriglyceridemia that result from systemic reductions in adipose tissue. Metreleptin, a synthetic analog of human leptin, is effective against generalized lipodystrophies; however, there are no reports of the use of metreleptin in the treatment of CGL4. Herein, we discuss the treatment of a six-year-old boy diagnosed with CGL4 due to a homozygous mutation in PTRF with metreleptin. His serum triglyceride level and homeostasis model assessment of insulin resistance (HOMA-IR) value decreased after two months of metreleptin treatment. However, the efficacy of metreleptin gradually decreased, and the treatment was suspended because anaphylaxis occurred after the dosage administered was increased. Subsequently, his serum triglyceride level and HOMA-IR value significantly increased. Anti-metreleptin-neutralizing antibodies were detected in his serum, which suggested that these antibodies reduced the efficacy of metreleptin and caused increased hypersensitivity. Thus, metreleptin appeared to be efficacious in the treatment of CGL4 in the short term, although an adverse immune response resulted in treatment suspension. Further studies are needed to evaluate metreleptin treatments for CGL4.

Cole-Carpenter syndrome is a rare skeletal dysplasia associated with low-bone mass or an osteogenesis imperfecta (OI)-like syndrome. Only 3 and 6 variants in SEC24D have been reported in patients with Cole-Carpenter syndrome type 2 and autosomal recessive OI, respectively. We describe a 15-year-old Japanese boy with short stature of the short-trunk type and craniofacial abnormalities including ocular proptosis, marked frontal bossing, midface hypoplasia, and micrognathia. These features were consistent with a diagnosis of Cole-Carpenter syndrome. He had low-bone mineral density and basilar impression. Whole exome sequencing analysis identified biallelic variants in SEC24D (p.Arg484* and p.Arg313His) in the patient. We will report a patient with compound heterozygous variants of SEC24D causing Cole-Carpenter syndrome type 2.

Endosalpingiosis is a benign condition characterized by the presence of tubal epithelium outside the fallopian tube and the absence of endometrial stroma. Florid cystic endosalpingiosis is a very rare form of endosalpingiosis that presents as a tumor-like lesion. We report the case of a 67-year-old woman who presented with a cystic lesion of the uterus. Macroscopically, a cut section revealed a multicystic, whitish mass in the myometrium of the fundus. Histologically, the lesion consisted of numerous variably sized glands that were lined with a single or stratified layer of ciliated columnar cells similar to tubal epithelium.

Thus, we clarified the association between some coping styles and insomnia among Japanese type 2 DM patients. Subjects and methods: The subjects included 503 type 2 DM patients (mean age 63.9±12.5years). Sleep disturbance and personality traits were evaluated using the Japanese version of the Pittsburgh Sleep Quality Index and the Brief Scale for Coping Profile, respectively. Lifestyle factors, glycated hemoglobin A1c (HbA1c) levels, and the depression statuses of the patients were also included in the analyses. Results: Among the 503 subjects with type 2 DM, 141 (28.0%) subjects exhibited probable insomnia. After adjusting for confounders, being female, living alone, and using “avoidance and suppression” were significantly correlated with current insomnia. No other relationships were found between insomnia and HbA1c or lifestyle factors, such as smoking, drinking alcohol, and exercise frequency. Conclusion: The prevalence of insomnia in individuals with type 2 DM was high, and the protective factors included some emotion-focused coping styles. Future prospective studies are required to confirm the therapeutic effects of behavioral interventions on insomnia in patients with type 2 DM.

Heart failure pandemic is rapidly approaching in Japan, requiring nationwide actions. In particular, the Japanese Circulation Society and related societies launched the Stroke and Cardiovascular Disease Control Act, which was passed by the National Diet, as the first ever legislative policy measure against stroke and cardiovascular disease. In association with this, actions against heart failure pandemic from the scientific field are also important. Because heart failure pandemic is a critical problem not only in Japan but also in many developed countries, we believe the nationwide approach, as summarized here, will greatly contribute to the development of cardiovascular medicine, particularly the management and treatment of heart failure worldwide.

There is concern that vitamin D deficiency is prevalent among children in Japan as well as worldwide. We conducted a nationwide epidemiologic survey of symptomatic vitamin D deficiency to observe its incidence rate among Japanese children. A questionnaire inquiring the number of new patients with vitamin D deficiency rickets and/or hypocalcemia for 3 years was sent to 855 randomly selected hospitals with a pediatrics department in Japan. In this survey, we found that 250 children were diagnosed with symptomatic vitamin D deficiency. The estimated number of patients with symptomatic vitamin D deficiency per year was 183 (95% confidence interval (CI): 145-222). The overall annual incidence rate among children under 15 years of age was 1.1 per 100,000 population (95% CI: 0.9-1.4). The second survey has provided detailed information on 89 patients with symptomatic vitamin D deficiency under 5 years of age in hospitals in the current research group. The nationwide and second surveys estimated the overall annual incidence rate of symptomatic vitamin D deficiency in children under 5 years of age to be 3.5 (2.7-4.2) per 100,000 population. The second survey revealed 83% had bowed legs, 88% had exclusive breastfeeding, 49% had a restricted and/or unbalanced diet and 31% had insufficient sun exposure among the 89 patients. This is the first nationwide survey on definitive clinical vitamin D deficiency in children in Japan. Elucidating the frequency and characteristics of symptomatic vitamin D deficiency among children is useful to develop preventative public health strategies.

Background Lymphovascular invasion (LVI) in high-grade clinical T1 bladder cancer is usually considered a poor prognostic factor, but it is often difficult to achieve correct staging of T1 bladder cancer and diagnose the presence of LVI because of the inadequacy of conventional transurethral resection specimens. The aims of this study were to evaluate the prognostic value of LVI in patients with correctly staged high-grade pathological T1 (pT1) bladder cancer who initially underwent transurethral resection in one piece (TURBO). Methods Eighty-six high-grade pT1 bladder cancer patients who underwent TURBO were enrolled. Risk of tumor understaging was avoided by examining the vertical resection margin of the TURBO specimen. Immunohistochemical staining using D2-40 and CD31 was performed to confirm LVI. We examined the association of LVI with other clinicopathological factors and the impact of LVI on progression-free survival and cancer-specific survival. Results The median follow-up period was 49 months (range, 6-142). In all patients, the tumors were accurately staged as pT1 at initial TURBO. LVI was detected in 15 patients (17%) and was significantly associated with tumor growth pattern (P = 0.001). Multivariate analysis identified LVI as the only independent predictor for reduced progression-free survival (HR, 4.48; 95% CI, 1.45-13.90; P = 0.009) and cancer-specific survival (HR, 4.35; 95% CI, 1.17-16.24; P = 0.029). Conclusions The presence of LVI in TURBO specimens independently predicts poor clinical outcomes in patients with high-grade pT1 bladder cancer. This information may help urologists to counsel their patients when deciding whether to choose a bladder-preserving strategy or radical cystectomy.

Objective Glycemic control varies based on lifestyle factors and stress coping mechanisms, which are influenced by personality. The psychological factors associated with glycemic control have not yet been established in patients with type 2 diabetes mellitus (T2DM). The relationship between a 5-factor model of personality and glycemic control was evaluated in individuals with T2DM. Methods The subjects were 503 Japanese outpatients with T2DM. Glycated hemoglobin A1c (HbA1c) levels, depressive status, insomnia and personality traits were assessed. Lifestyle factors of the patients, such as habitual alcohol consumption and smoking, were also included in the analyses. Results Because the influence of insulin therapy on HbA1c is so strong, we stratified the patients according to insulin use. Simple regression analysis showed a significant correlation between HbA1c and neuroticism in patients who did not use insulin. After adjustment for confounders, multiple regression analyses revealed that none of the personality factors, including neuroticism, were found to be associated with HbA1c. Conclusion These findings suggest that personality traits do not have a large impact on glycemic control. Further studies are required to confirm the relationships between psychological factors and glycemic control using a longitudinal study design.

Aims/Objectives Glycemic control varies according to stress level and the efficacy of control measures, affecting the outcomes of diabetes. Although detailed coping styles have not been well studied in patients with type 2 diabetes mellitus, problem‐focused coping strategies are believed to be related to better control of blood glucose. Associations between coping profiles/dimensions and blood glucose control were examined in individuals with type 2 diabetes. Materials and Methods The participants included 503 Japanese patients (mean age 63.9 ± 12.6 years) with type 2 diabetes. The average glycated hemoglobin A1c (HbA1c) levels were calculated from HbA1c levels measured more than four times within the 12 months before the assessment. Coping profiles were assessed using the Brief Scale for Coping Profile. Lifestyle factors were also included in the analyses. Results Factors other than age were not associated with HbA1c levels in patients who used insulin. Conversely, habitual alcohol consumption, single status, the adaptive emotion‐focused coping dimension, and changing mood and changing one’s point of view profiles were associated with HbA1c levels. Conclusions These findings suggest that adaptive emotion‐focused coping supports glycemic control in type 2 diabetes patients who do not use insulin. Additional studies using a longitudinal design are required to further examine the relationships between psychological factors and glycemic control., This study investigated coping styles associated with glucose control in people with type 2 diabetes. An adaptive emotion‐focused coping dimension supports glycemic control in people with type 2 diabetes who do not use insulin.

The combination chemotherapy regimen of eribulin (ERI) and trastuzumab (TRA)—the ERI-TRA regimen—has been shown to be highly tolerable for patients with recurrent or metastatic human epidermal growth factor receptor 2 (HER2)-positive breast cancer. However, no sufficient clinical evidence is available for the long-term safety profile of the regimen. We report on three patients in the Phase I combination study of the regimen, for whom the regimen could be conducted over the long term. Patient #1 was a 68-year-old woman and underwent the regimen until cycle 23. Patient #2 was a 61-year-old woman and underwent the regimen until cycle 27. Patient #3 was a 59-year-old woman and underwent the regimen until cycle 22. All these patients had undergone TRA-based combination therapy before the onset of the regimen. Any new categories of adverse events did not occur in association with the long-term combination chemotherapy. Neutropenia experienced by these patients was reversible and easily manageable by dose adjustment (interruption/delay and reduction). Neither increase in the risk of cardiomyopathy nor the worsening of peripheral neuropathy greater than grade 1 was found. The present regimen was suggested to be a novel chemotherapeutic option for patients with HER2-positive recurrent or metastatic breast cancer. The fact that the long-term ERI-TRA regimen was successfully conducted for these patients can be supplementary clinical information that is beneficial for clinical oncologists.

OBJECTIVE Serum amino-terminal propeptide of C-type natriuretic peptide (NT-proCNP) levels have been proposed as a biomarker of linear growth in healthy children. The usefulness of NT-proCNP in patients with achondroplasia (ACH)/hypochondroplasia (HCH) remains to be elucidated. The objective was to study whether serum NT-proCNP level is a good biomarker for growth in ACH/HCH and other patients of short stature. DESIGN This was a longitudinal cohort study. PATIENTS Sixteen children with ACH (aged 0·4-4·3 years), six children with HCH (2·7-6·3 years), 23 children with idiopathic short stature (ISS) (2·2-9·0 years), eight short children with GH deficiency (GHD) (2·9-6·8 years) and five short children born small for gestational age (SGA) (2·0-6·6 years). Patients with ACH/HCH received GH treatment for 1 year. MEASUREMENTS Serum NT-proCNP levels and height were measured. RESULTS NT-proCNP levels positively correlated with height velocity in these short children (P < 0·05, r = 0·27). NT-proCNP levels inversely correlated with age in children with ISS alone (P < 0·01, r = -0·55). Serum NT-proCNP levels in patients with ACH/HCH were increased 3 months following the initiation of GH treatment (P < 0·05). Height SDS gain during GH treatment for 1 year was positively correlated with the changes in NT-proCNP levels after the initiation of GH (P < 0·01, r = 0·72). CONCLUSION Serum NT-proCNP levels may be a good biomarker to indicate the effect of GH treatment on growth in patients with ACH/HCH at least in the first year and height velocity in short stature patients.

Objective Type 2 diabetes mellitus (T2DM) is associated with a high prevalence of depression, which is influenced by personality traits and coping style. However, these psychological factors have not been well studied in individuals with T2DM. The association between coping behaviors and the reported levels of depressive symptoms was examined in individuals with T2DM. Methods The subjects were 435 T2DM patients (mean age 63.1 ± 12.6 years). Depressive status, personality traits and coping behaviors were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D) and the Brief Scale for Coping Profile (BSCP). Lifestyle factors and glycated hemoglobin A1c (HbA1c) levels in the patients were also included in the analyses. Results Among the 435 subjects with T2DM, 130 (29.9%) exhibited possible depression, and 68 (15.6%) displayed probable depression. After adjustment for confounders, logistic and multiple regression analyses revealed that certain coping profile scores, such as Changing one’s point of view, Emotional expression involving others and Avoidance and suppression, were consistently and significantly associated with the presence and severity of depression. No relationship was found between depression and HbA1c. Conclusion These findings indicate that Maladaptive emotion-focused coping strategies, such as Emotional expression involving others and Avoidance and suppression, are protective factors and that Adaptive emotion-focused coping, such as Changing one’s point of view, is a risk factor for depression in T2DM patients. Psychological intervention focusing on the coping profile may reduce depressive symptoms. Additional studies are needed to examine the relationships between psychological factors and depressive symptoms using a longitudinal study design.

The onset of type 2 diabetes mellitus(T2DM) is based on the insulin resistance and decreasing of insulin secretion. Residual β-cell function is a key factor in achieving optimal glycemic control in patients with type 2 diabetes. Glucagon induces insulin secretion by direcdtly stimulating β-cells, therefore glucagon stimulaton test(GST) is a reliable marker for β-cell function. Fasting C-peptide(CPR)-index(CPR[ng/ml] to glucose[mg/dl] ratio x100; F-CPRI) is used as a marker of insulin secretion. We evaluated the efficacy of postprandial CPR to glucose ratio(P-CPRI) as a tool for evaluating β-cell function. Japanese T2DM patients with inadequte glycemic control(HbA1c>7.0%) were enrolled in the study(n=333, insulin therapy =217). HbA1c, fasting CPR and glucose were measured, and F-CPRI was calculated. Postprandial(120 min after breakfast) CPR and glucose were measured, and P-CPRI was calculated. For the GST, CPR was determinated before and 6 min after 1mg of glucagon injection. GSTδCPR(CPR[6 min] - CPR[0 min]) was calculated. Factors correlated with GSTδCPR were analyzed using simple and multiple stepwise regression analysis. P value Disclosure Y. Matsuhashi: None. S. Chikazawa: None. H. Nakayama: None. M. Murabayashi: None. S. Mizushiri: None. S. Osonoi: None. K. Takahashi: None. H. Otaka: None. M. Yanagimachi: None. H. Murakami: None. M. Daimon: None.

The Stroke and Cardiovascular Disease Control Act was enacted in Japan in December 2018. This law has become the first ever legislative countermeasure against stroke and cardiovascular disease in Japan. The government shall make a “Basic Plan to Promote Stroke and Cardiovascular Disease Control Programs” with input from a council consisted of stakeholders. In accordance with the government plan, each prefecture shall make a prefectural plan. Both government and prefectural plans will be reviewed at least every six years. A nationwide approach is expected to contribute to reducing the burden of disease and to prolong healthy life expectancy.

Background: An immediate ambulance call offers the greatest opportunity for acute stroke therapy. Effectively using ambulance services requires strengthening the association between knowledge of early stroke symptoms and intention to call an ambulance at stroke onset, and encouraging the public to use ambulance services. Methods: The present study utilized data from the Acquisition of Stroke Knowledge (ASK) study, which administered multiple-choice, mail-in surveys regarding awareness of early stroke symptoms and response to a stroke attack before and after a 2-year stroke education campaign in two areas subject to intensive and moderate intervention, as well as in a control area, in Japan. In these three areas, 3833 individuals (1680, 1088 and 1065 participants in intensive intervention, moderate intervention, and control areas, respectively), aged 40 to 74 years, who responded appropriately to each survey were included in the present study. Results: After the intervention, the number of correctly identified symptoms significantly associated with intention to call an ambulance (P < 0.05) increased (eg, from 4 to 5 correctly identified symptoms), without increasing choice of decoy symptoms in the intensive intervention area. Meanwhile, in other areas, rate of identification of not only correct symptoms but also decoy symptoms associated with intention to call an ambulance increased. Furthermore, the association between improvement in the knowledge of stroke symptoms and intention to call an ambulance was observed only in the intensive intervention area (P = 0.009). Conclusions: Our results indicate that intensive interventions are useful for strengthening the association between correct knowledge of early stroke symptoms and intention to call an ambulance, without strengthening the association between incorrect knowledge and intention to call an ambulance.

Energy is a critical component of achieving sustainable development. In addition to the three aspects of promoting access, renewables, and efficiency, the dimension of resilience in energy systems should also considered. The implementation of resilient energy systems requires a quantitative understanding of the socio-economic practices underlying such systems. Specifically, in line with the increasing globalization of trade, there remains a critical knowledge gap on the link between embodied energy in the production and consumption of traded goods. To bridge this knowledge gap, we investigate the resilience of global energy systems through an examination of a diversity measure of global embodied electricity trade based on multi-regional input-output (MRIO) networks. The significance of this research lies in its ability to utilize high resolution MRIO data sets in assessing the resilience of national energy systems. This research indicates that secure and responsible consumption requires the diversification of not only energy generation but also energy imports. This research will lay the ground for further research in the governance of resilience in global energy networks.

Background Renal cell carcinoma is well-known for its propensity to metastasize to unusual sites. However, metastasis to the gallbladder has been rarely reported in the literature. Case presentation A 75-year-old Japanese (Asian) woman presented for further evaluation of a gallbladder polyp, 15 years after right radical nephrectomy for renal cell carcinoma. Computed tomography revealed a 12 mm enhancing pedunculated tumor in the gallbladder fundus. Open simple cholecystectomy was performed and the tumor was histologically confirmed as a metastasis of renal cell carcinoma to the gallbladder. Our patient is alive and has been disease-free for 3 years after cholecystectomy. Conclusions Although metastasis of renal cell carcinoma is a rare differential diagnosis of gallbladder tumors, simple cholecystectomy is likely to offer a chance of long-term survival for patients with gallbladder metastases of renal cell carcinoma.

Cystic lymphangiomas of the mesocolon are very rare in adults. They are usually asymptomatic, but can present with an acute abdomen. We report an adult patient with cystic lymphangioma of the mesocolon that manifested with peritonitis. A 33-year-old man presented with fever and severe pain with muscle guarding in the left abdomen. Laboratory data indicated high-grade inflammation. Enhanced computed tomography (CT) showed multiple low-density masses with peripherally enhancing rims, strongly suspicious for cysts, in the left abdomen. Based on a diagnosis of peritonitis, emergency surgery was performed and revealed many cysts in the descending mesocolon. Histopathological examination findings indicated a cystic lymphangioma. The post-operative course was uneventful, and 1-year follow-up CT showed no recurrence. This case demonstrates that cystic lymphangiomas of the mesocolon in adults can present with acute peritonitis, although this is extremely rare. Complete resection is required for accurate diagnosis and for preventing recurrence.

A large amount of municipal and industrial flood waste was generated during a 2011 monsoon in Thailand. This paper examines the generation and disposal of flood waste related to Thailand floods using data obtained through field surveys and interviews with involved organizations. As a result, problems with flood waste treatment were found. These included a shortage of waste collection capacity such as vehicles and boats under emergency conditions, a lack of appropriately designed temporary waste storage at waste transfer stations, a lack of recycling systems for the wood waste that dominated waste from flooding, and the possibility thatmixed disposal ofmunicipal and industrial waste introduced contamination. To improve flood waste treatment, some proposals were provided for the predisaster, disaster and post-disaster stages.

Large cell neuroendocrine carcinoma (LCNEC) of the uterine cervix is very rare and aggressive. The prognosis is very poor despite multimodal treatment. We report a virgin woman with FIGO stage 4b LCNEC of uterine cervix coexisting with squamous cell carcinoma. An early thirties virgin woman presented with 2-month history of abdominal pain. A chest X-ray showed multiple lung metastatic tumors. A vaginal smear showed malignant cells, and a biopsy specimen had features of LCNEC. The tumor showed trabecular patterns. Tumor cells possessed a moderate amount of cytoplasm, prominent nucleoli, and large nuclei. The tumor cells are stained positive for synaptophysin, chromogranin A, and neuron specific enolase (NSE). The invasive tumor cells in connection with cervical squamous epithelium were focally positive for 34bE12. We made a diagnosis of composite LCNEC and nonkeratinizing squamous cell carcinoma. High-risk HPV test was negative with hybridized captured method 2.

A 66-year-old woman presented with a 2-year history of asthma has progression of dyspnea within a week, and a computed tomography (CT) revealed an endotracheal tumor at level of aortic arch. The resected tumor, measured by 18 × 12 × 10 mm, has histologically malignant features including frank invasion with desmoplastic stroma and foci of necrosis. Presence of glycogen and mucin was confirmed by periodic acid-Schiff (PAS) and diastase PAS staining. Immunohistochemically, the tumor cells were diffusely positive for cytokeratin (CK) 7 and AE1/3, focally positive for CK5/6 and CK14, but negative for CK20. Thyroid transcription factor-1 (TTF-1), Napsin A, and SP-A, indicating lung parenchymal origin were all negative. Other muscular markers, neuroendocrine markers, renal cell carcinoma markers, and markers related to perivascular epithelioid cell tumors were all negative. Postoperative systemic examination suggests no primary tumor outside the lung. The follow up was excellent being recurrence free for 14 months in spite of the positive surgical margin by the tumor cells. This is a first report of rare neoplasm, clear cell carcinoma of salivary gland type, presenting as an endotracheal mass.

Background: It is important that the general population be aware of the early symptoms, since it has been shown that early arrival to hospitals leads better prognosis of stroke patients. However, the general population is not well informed about the early symptoms of stroke. This study was conducted to clarify which stroke symptoms are less well known and which information sources are related to awareness of stroke symptoms. Methods: A multiple-choice, mail-in survey involving 5,540 randomly selected residents, aged 40-74 years, of 3 cities in Japan was conducted. Their knowledge about stroke symptoms and their information sources were surveyed; information sources were classified as mass media (television/newspaper/radio) and personal communication sources (posters/leaflets/internet/health professionals/family and/or friends). ‘Awareness' was defined as selecting all 5 of the correct stroke symptoms from among 10 listed symptoms with decoy choices. The estimated fraction of the possible impact due to each source on the whole population was also calculated by odds ratios (ORs) and the proportion of respondents who selected each source (Pe). The combined effects of mass media and personal communication sources on awareness were also assessed. Results: Of the 5,540 residents, only 23% selected all 5 correct symptoms. Visual disturbance was the least known of the 5 symptoms (35%). All sources were positively related to awareness, with ORs (Pe) of: television, 1.58 (72.5%); newspaper, 1.79 (48.0%); radio, 1.74 (13.3%); posters, 1.73 (7.6%); leaflets, 1.50 (24.7%); Internet, 1.66 (5.6%); health professionals, 1.33 (34.8%), and family/friends, 1.21 (44.6%). The estimated fraction of the possible impact due to each source was higher for mass media (television, 0.31 and newspaper, 0.28) than personal communication sources (Internet, 0.04 and leaflets, 0.12). Mass media only and mass media/personal communication sources were significantly associated (ORs: 1.66, 2.75, respectively). Conclusions: As a single method of public education, television could be the most effective strategy. Moreover, the combined approach involving mass media and personal communication sources might have a synergistic effect. Less well-known symptoms, such as visual disturbances, should be noted in public education campaigns.

S-1 plus cisplatin is the standard chemotherapy for recurrent gastric cancer. While depression and delirium are frequent in cancer patients, hypomania during chemotherapy is rare. We describe a rare case of hypomania during S-1 plus cisplatin treatment for recurrent gastric cancer. A 66-year-old woman, with no previous psychiatric disorder, received S-1 plus cisplatin for recurrent gastric cancer. She showed peculiar behavior. Physical examination, urine, blood and imaging findings were normal. There was no gastric cancer progression. During psychiatric consultation, she behaved inappropriately. However, she behaved normally while performing daily activities. She manifested a persistently elevated, expansive or irritable mood, clearly different from her usual non-depressed state, meeting hypomania diagnostic criteria. Her condition did not require chemotherapy discontinuation or additional medication. During the second and subsequent S-1 plus cisplatin cycles, symptoms were stable. Cancer patients often have adjustment disorders, depression and delirium, but rarely hypomania. Our patient showed no significant changes in blood biochemistry and brain and whole body imaging. While S-1 plus cisplatin-induced hypomania cannot be excluded, hypomanic symptoms did not improve during the chemotherapy rest period, nor was there deterioration during subsequent cycles, suggesting drug-induced mania to be unlikely. Possible onset mechanisms include manic defense phenomena, common with stressful life events. There are no reports of recurrent gastric cancer patients experiencing hypomania during S-1 or S-1 plus cisplatin therapy, i.e. our patient represents a rare course. Clinicians should recognize psychosis or mood disorders during gastric cancer treatment. Further accumulation of such rare cases might elucidate pathological mechanisms underlying hypomania in cancer patients.

This study estimates the overall cost savings that have been realized due to disposal of inert wastes in Japan because this material has been deposited in inert waste landfills (IWLs) that are designed exclusively for this purpose, instead of being co-dipsosed with organic wastes in more costly in sanitary landfills (SLs). The total realized cost savings were based on the disposed volume of inert waste and the actual disposal fees for IWLs and SLs for the period 1977–2006. The estimated reduction in expense is 4748 billion JPY for the period. On the other hand, if organic wastes had been deposited in IWLs along with inert wastes, costs would be incurred to clean up the sites because the surrounding environment may be polluted by the decomposition of the non-inert wastes and considerable efforts probably would be required to restore the polluted environment to its normal condition (this is because IWLs typically do not have a barrier system.) The potential cleanup cost was estimated to be 616 to 1226 billion JPY. These estimated costs were compared and it was found that the net reduction in expense was 3522 billion to 4122 billion JPY. Although the expense was reduced substantially, it was noted that a considerable cleanup cost would be generated. In particular, it was found that the increase in cleanup costs becomes most significant after the late 1990s

Objectives: To demonstrate the usefulness of transurethral resection in one piece (TURBO) as an accurate pathological staging tool for bladder tumor. Methods: Ninety-seven patients with newly diagnosed bladder cancer underwent TURBO that was performed either in an en bloc or in a divisional manner. The histological quality of the resection specimens was evaluated and the pathological stage was assigned on the basis of the depth of invasion, which was histologically determined. Results: Specimens obtained by TURBO were well oriented and their 3-D architecture was maintained. This allowed a histological assessment of the entire specimen. Portions of muscularis propria were identified beneath the tumor base in the specimens of 80 (82%) patients. In only seven (7%) patients, the tumors had a deep resection margin positive for carcinoma and were ambiguously staged as “pT1 or higher” or “pT2 or higher”. Thus, definite pathological staging of TURBO specimens was possible in 90 (93%) patients (pTa, 30; pT1, 58; pT2, 2). Conclusions: An accurate pathological stage can be assigned to the TURBO specimen in most bladder cancer patients.

We report a case of sylvian hematoma enlarging 3 days after neck clipping for a ruptured anterior communicating artery aneurysm, in the contralateral sylvian fissure to the operative approach. This 65-year-old man was admitted with sudden loss of consciousness by ambulance. Angiography revealed a saccular aneurysm at the anterior communicating artery complex, measuring 2.3×2.4 mm and pointing inferiorly. The aneurysmal neck was successfully clipped by using the right pterional approach. To minimize predictable vasospasm, the hematoma in the left sylvian stem was removed. Postoperative CT scan showed a considerable decrease in hematoma in the basal cistern, but a slight decrease in the vertical portion of the left sylvian fissure. The patient’s consciousness gradually recovered, but deteriorated again 3 days after the operation. CT scan showed a large high-density area in the sylvian fissure suggesting unexpected enlargement of sylvian hematoma. A left fronto-temporal craniotomy was performed. When the subpial hematoma around the sylvial fissure was removed, a large amount of bloody cerebrospinal fluid (CSF) flowed out. The cavity containing bloody fluid was located in the temporal lobe. Postoperative course was uneventful. He recovered well, but moderate sensory aphasia remained. Sylvian hematoma is rarely associated with ruptured anterior communicating artery aneurysms. Furthermore, there has been no report describing delayed onset sylvian hematoma as far as we are aware. The following mechanism was considered to explain this very rare condition. Removal of subarachnoid hematoma in the left sylvian fissure made a recovery of CSF flow up to the limen insulae, but CSF appeared to be blocked from entering the distal sylvian fissure by the thick subpial sylvian hematoma. Instead of normal CSF flow route, CSF may enter into the weakened subpial space to allow accumulation of bloody CSF in the temporal lobe. Subpial hematoma may act as a one-way valve.

A 61-year-old woman was referred to our hospital with epigastralgia and appetite loss. Barium examination and upper gastrointestinal endoscopy revealed uneven erythematous mucosa with multiple elevated lesions from the gastric fornix to the upper corpus. Abdominal computed tomography showed thickening of the wall of the fornix and swelling of perigastric lymph nodes, but whole-body gallium scintigraphy and bone marrow examination did not indicate further involvement. Biopsy specimens showed diffuse infiltration of large atypical lymphoid cells in which Epstein-Barr virus (EBV) was detected by in situ hybridization. Diffuse large B-cell lymphoma (DLBCL), stage II1, was diagnosed. Combination chemotherapy [cyclophosphamide, adriamycin, vincristine, and prednisone (CHOP)], was given, and this was followed by radiotherapy. Partial remission was achieved by chemotherapy, but the disease progressed rapidly during radiotherapy. Because the reported prognosis of EBV-positive DLBCL is unfavorable, the therapeutic strategy for EBV-positive gastric DLBCL should be considered carefully.

To examine whether dexamethasone suppression can reduce fluorine 18 fluorodeoxyglucose (FDG) uptake in false-positive (FP) findings in pulmonary and mediastinal lymph nodes in non-small cell lung cancer (NSCLC).Institutional ethics review board approved this prospective study with written informed consent. The study population was composed of 17 patients with NSCLC who underwent both baseline and dexamethasone suppression (24 hours after oral administration of 8 mg dexamethasone) FDG positron emission tomography/computed tomography and surgery. FDG uptake was evaluated by using a five-point visual scoring system (negative findings, score of 0-1; positive findings, score of 2-4) and maximum standardized uptake value (SUVmax). The Mann-Whitney U, Wilcoxon signed-rank, Kruskal-Wallis, or Spearman rank correlation tests were used as necessary for statistical evaluations.In 17 primary lesions, no significant difference was noted in visual score between baseline (mean, 3.4 ± 1.2) and dexamethasone suppression scans (mean, 3.3 ± 1.2; P = .16), although SUVmax was significantly lower on dexamethasone suppression scans (mean, 7.1 ± 5.2) than on baseline scans (mean, 8.6 ± 6.6; P = .005). In eight nodes with true-positive (TP) findings, there were no significant differences in visual score (mean for both, 3.8 ± 0.5) and SUVmax (mean, 5.3 ± 2.3 vs 5.5 ± 2.5, respectively; P = .81) between baseline and dexamethasone suppression scans. In 19 nodes with FP findings at baseline, dexamethasone suppression resulted in significantly lowered visual score (mean, 3.4 ± 0.6 vs 2.4 ± 0.8, respectively; P.001) and SUVmax (mean, 3.5 ± 0.8 vs 2.7 ± 0.7, respectively; P.001), and four nodes with FP findings were rated as true-negative findings on dexamethasone suppression scans, which resulted in a significant difference in SUVmax between nodal lesions with TP and FP findings (P = .014).Oral dexamethasone has the potential to reduce FDG uptake in pulmonary and mediastinal nodes with FP findings in NSCLC.

According to official Chinese statistics, sulfur dioxide emissions dropped significantly in the late 1990s before rising again. Some researchers have expressed concern over data reliability, however, and the sample of enterprises represented by sulfur dioxide emission statistics generates only one third of China’s industrial output, which may result in undercounting of emissions. In addition, coal production and consumption during the late 1990s may have been undercounted due to politically motivated manipulation of numbers, and this phenomenon may also partly explain the reported reductions in sulfur dioxide emissions. Coal sulfur content derived from coal supply-side information is generally found to be higher than from demand-side information used to calculate emissions for official statistics. Meanwhile, no solid data are available that demonstrate improvement of the desulfurization of smokestack emissions. All of these are potential factors in the underestimation of China’s emissions.

Gastric carcinogenesis is a multistep process, during which numerous genetic and epigenetic alterations accumulate: there are abnormalities of growth factors/receptors, angiogenic factors, cell cycle regulators, DNA mismatch repair genes etc. These abnormalities define, at the same time, the biological character of the cancer cell and may thus serve as therapeutic targets. Genetic instability may cause accumulation of genetic abnormalities. The most important epigenetic alterations are DNA methylation, histone modification and chromatin remodeling. Some of these changes are common in gastric cancer, regardless of subtype, and some differ by histological type or (gastric or intestinal) mucin phenotype. Genetic polymorphism is a crucial endogenous cause and fundamental aspect of cancer risk. Importantly, genetic polymorphisms are also associated with the therapeutic efficacy and toxicity of anti-cancer drugs. Genomic science and technology such as Serial Analysis of Gene Expression (SAGE) allows the identification of novel genes and molecules specifically up-regulated or down-regulated in gastric cancer, e.g., RegIV and claudin-18 can be identified. Advances in our understanding of the genetic and molecular bases lead to improved diagnosis, personalised medicine and prevention of gastric cancer.

背景:穿刺吸引細胞診にて, 甲状腺乳頭癌の一部に粘液含有細胞や異型角化扁平上皮細胞が同時に認められたきわめてまれな症例を経験したので報告する.症例:67歳, 男性. 左頸部リンパ節腫脹を主訴に受診. エコー検査にて左頸部に4cm大, そのすぐ下に3cm大, 甲状腺左葉に0.7cm大の腫瘤を認め穿刺吸引細胞診が施行された. 両者ともにclass Vと診断され, 甲状腺左葉・左頸部リンパ節切除術が施行された. 細胞診では甲状腺左葉は乳頭癌, 左頸部リンパ節は甲状腺乳頭癌のリンパ節転移と考えられた. また, 粘液含有細胞や異型角化扁平上皮細胞 (粘表皮成分) が甲状腺左葉では少数, 左頸部リンパ節では比較的多く認められた. 切除標本では甲状腺左葉は大部分が高分化型乳頭癌で, その中に粘表皮成分がごく少数含まれていた. 左頸部リンパ節転移巣では高分化型乳頭癌に加え, 粘表皮成分が混在していた. サイログロブリンは乳頭癌細胞で陽性であったが, 粘表皮成分は陰性であった.結論:粘表皮成分は原発巣より転移巣で多く認められ, 粘表皮成分の出現は甲状腺乳頭癌の化生性変化と考えられた.

BACKGROUND AND PURPOSE The very old are expected to become a growing part of the stroke population in the industrialised part of the world. The aims of this study were to evaluate clinical characteristics of patients aged 85 years or more at stroke onset and to investigate very old age as an independent predictor of short- and long-term outcome. METHODS In the community-based Copenhagen Stroke Study we recorded admission clinical characteristics in 1197 consecutive stroke patients. Patients were stratified according to age groups on admission. Follow-up was performed at a mean of 7 years after stroke onset. By way of multiple logistic regression and survival analyses very old age was independently related to short- and long-term mortality and nursing home placement independent of other clinical characteristics. RESULTS 16% of patients were 85 years or older at the time of stroke onset. More of the very old were women (75% versus 50%, P
