The aim of the present study was to measure the amount of nerve growth factor (NGF) present in saliva, and investigate the relationship with aging, gender, and number of retained teeth. The subjects were 93 healthy volunteers (35 males and 58 females) aged 18-87 years. Stimulated saliva was collected during gum chewing, and saliva secretion per minute and NGF concentration per unit volume were measured by enzyme-linked immunosorbent assay. We found that NGF in saliva was measurable in all subjects. The mean NGF concentration in saliva was 55.70 ± 38.27 pg/ml, and no relationship was found between NGF concentration and aging, gender, and the number of retained teeth. The mean NGF amount in saliva was 84.38 ± 71.06 pg/min. The NGF amount in saliva decreased with age, especially for the group aged 70 years and older. It was higher in male than female subjects, and was significantly higher in the group without tooth loss compared to the edentulous group. In addition, regarding the relationship between the saliva flow rate per minute and NGF amount in saliva, the latter increased significantly with a rise in the former. These results indicate that the NGF amount in saliva is influenced by aging, masticatory function, and saliva amount. It is speculated that human salivary glands play an important role in the synthesis and expression of NGF.

A 48-year-old female who was diagnosed as having a right aortic arch with retroesophageal left subclavian artery and left ligamentum arteriosus was referred to our hospital for an aortic arch and descending aortic aneurysm with a dilated Kommerell's diverticulm. This aneurysm was 67mm in maximum diameter, between the aortic arch and the midportion of the descending aorta. Successful surgical treatment was accomplished with the use of extraanatomic bypass grafting between the ascending aorta and the descending aorta and reconstruction of the four main branches of the aortic arch. Postoperative digital subtraction angiography and enhanced CT revealed slight leakage at the distal stump of the aneurysm. Theoretically, resection of the aneurysm and aortic reconstruction would have been the best procedure. However, the complicated anatomy made it difficult to perform total resection of the aneurysm and aortic reconstruction, and several problems remained after operation.

Integrated Distress Activity Score (IDAS) was developed in order to evaluate both positive and negative aspects of patient’s conditions throughout hospitalization. IDAS were evaluated by nurses everyday and when patients continued to have IDAS less than or equal to zero, we used this tool for determining continuous deep sedation. From 2013-2017, 1306 patients were enrolled in the study. The average rate of continuous deep sedation in the PCU was 1.2%(16 patients). Dyspnea was the most common condition (62.5%, 10 patients), followed by delirium (37.5%, 6 patients).The average days that took to decide for sedation (from the day when IDAS was less than or equal to zero), was 3.7 days. This study suggested that IDAS could be a useful tool for determining continuous deep sedation.

A 76-year-old man who suffered from consistent back pain was admitted for anti-hypertensive therapy to strictly manage the early thrombosed acute type A aortic dissection (AAAD). On admission, his blood pressure could not be controlled well ; soon he complained of recurrent severe back pain. The second thoracoabdominal enhanced computed tomography revealed the progression of AAAD from DeBakey type II to type I with thrombosed pseudolumen at the descending thoracic aorta ; therefore, emergent surgical intervention by primary central repair was conducted. Paraplegia was diagnosed eight hours after surgery, then cerebrospinal fluid drainage and intravenous administration of Naloxone were started immediately followed by keeping the systemic blood pressure more than 120 mmHg. However, paraplegia had never improved and been persistent with neurological deficit of the lower extremities. We herein report a complicated surgical case of an AAAD patient with paraplegia and review the complex clinical settings.

Advanced cancer patients experience stress and are at risk for developing psychological problems. Early diagnosis and suitable intervention are very important for their quality of life and compliance with chemotherapy. The Hospital Anxiety and Depression Scale (HADS) is one of the most commonly used mood scales; however, HADS has not been validated for use with cancer patients undergoing chemotherapy. The purpose of this study was to validate HADS as a screening tool for psychological distress among cancer patients undergoing chemotherapy. We also identified possible factors contributing to psychological distress and explored the development of original screening tools. Fifty subjects agreed to complete HADS and consult with psychiatric specialists. Possible contributing factors to psychological distress were identified by HADS and logistic regression analysis. The mean score for patients with psychological distress was 20.0 ± 8.93, and for patients without distress was 9.67 ± 6.11; scores for patients with psychological distress were significantly higher. The optimal cutoff point of psychological distress appeared to be 17. This cutoff point was associated with 72.7% sensitivity and 82.1% specificity. The factor “recurrent cancer” (p=0.043) had an odds ratio of 7.24 (1.21-61.2). We verified that HADS is a useful screening tool for cancer patients undergoing chemotherapy. The factor “recurrent cancer” was shown to contribute to psychological distress. Palliat Care Res 2011; 6(2): 150-157

Purpose: Escitalopram has been inadequately evaluated in cancer patients. Here, we report two patients with advanced cancer who benefited from escitalopram for depression. Case 1: A man aged in his 50s had postoperative recurrence of rectal cancer. He was diagnosed with a major depressive episode according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). The score of the Hamilton Rating Scale for Depression (HAMD-17) was 20 points. He began treatment with 10 mg/day of escitalopram. His symptoms began to improve at about 14 days, and the HAMD-17 score was 4 points at 23 days, suggesting a marked improvement. Case 2: A woman aged in her 50s had cancer of the external auditory canal. She was diagnosed with a major depressive episode according to DSM-IV-TR. The score of HAMD-17 was 26 points. She began treatment with 10 mg/day of escitalopram. Her symptoms began to improve at 15 days, and the HAMD-17 score at 28 days was 13 points, suggesting a marked improvement. In both cases, serious side effects, clear exacerbation of depression, and withdrawal syndrome due to acute drug deprivation associated with worsening of the symptoms were not noted. Conclusion: Escitalopram is considered a useful drug for depression in patients with advanced cancer.

Objective: This study aimed to confirm whether the methods for assessing the reported causal relationship between dietary supplement intake and adverse events are reliable in the clinical setting.
Design: The relationships between supplement intake and adverse events were assessed using two algorithms proposed in our previous report, and causal relationships were evaluated.
Methods: Twelve raters with a high probability of handling adverse event information examined 200 records of dialogues with supplement users.  Each rater independently assessed the causal relationship using the two algorithms.  The relationships between supplement intake and adverse events were assessed for all 200 cases.  Variability in the evaluation among raters was analyzed for each occupation and the whole group of raters.  The distributions of evaluation were analyzed, and inter-rater reliability was evaluated using the intraclass correlation coefficient (ICC) and Fleiss’ kappa coefficient.
Results: All events of 200 cases seemed to be slight and within the range of variation in daily life.  Almost all cases were classified into two categories as “Possible” and “Lack of Information” by each rater.  The ICC values for all raters, pharmacists, dieticians, and health care workers were 0.644, 0.573, 0.678, and 0.694, respectively, and the kappa coefficients using the two algorithms were 0.466, 0.426, 0.468, and 0.519 and 0.481, 0.478, 0.465, and 0.517, respectively.  There were moderate levels of agreement based on the kappa coefficients and ICC values.
Conclusion: The two algorithms proposed in our previous report may be reliable in the clinical setting.  Their reliability could be enhanced by establishing a unified method of accumulation and recording adverse events for supplement intake, which should be evaluated by more raters using more cases of adverse events.

A 67-year-old man presented complaining of unstable angina. Coronary angiography revealed 50% stenosis of the left main trunk of the left coronary artery and a coronary artery aneurysm in the left anterior descending artery (LAD) #6. Furthermore, significant stenosis was noted in the peripheral LAD #7 and #9. The patient had hepatitis C, probably due to an earlier transfusion, and was suffering from liver cirrhosis (Child-Pugh classification grade A) and advanced thrombocytopenia. We anastomosed the saphenous vein graft (SVG) to the LAD and diagonal branch by off-pump coronary artery bypass grafting; we did not treat the aneurysm. There were no postoperative complications and the patient's progress was good. On postoperative coronary angiography, the aneurysm was occluded and the patency of the SVG was satisfactory.

We experienced the coronary artery bypass grafting (CABG) with essential thrombocythemia (ET). A case is a man of 73 years old. As for him, 3 vessel disease including left main trunk was recognized on coronary angiography, and it was planned CABG. However, we recognized blood cell aberration in blood examination, and it was diagnosed as ET. ET is classed as a chronic myeloproliferative disorder. It has two opposite tendencies, a bleeding tendency and thrombus tendency. Ischemic heart disease to merge ET is acute myocardial infarction by thrombus in case of most, and there are a few cases to need blood circulation reconstruction of coronary artery for angina pectoris. Perioperative hemorrhage and postoperative graft closure become a problem in CABG with ET. With the hydroxycarbamide which is DNA synthesis inhibitor of a platelet count, a function controlled it, and enforced CABG. He doesn't have any cardiac events and complications due to ET for 7 years post CABG. We report this case with a review of the literature.

Objective: The objective of this study was to validate the Japanese version of the STOP-Bang test for risk assessment of obstructive sleep apnea syndrome (OSAS).Methods: We retrospectively evaluated inpatients who underwent nocturnal pulse oximetry for OSAS screening at the internal medical wards.Results: One hundred and forty-four subjects were included the study, and 57 subjects who had a 3% oxygen desaturation index ≥10/hr underwent polysomnography. Seventeen and 29 subjects were diagnosed with moderate and severe OSAS, respectively. According to the receiver operating characteristic (ROC) curve analysis, the STOP-Bang test had a higher diagnostic value using a cutoff of 30 kg/m2 for BMI than using a cutoff of 35 kg/m2. A STOP-Bang score of 3 or greater had a sensitivity of 95.7% and specificity of 42.9% for detecting moderate-to-severe OSAS.Conclusion: The STOP-Bang test is a simple and useful tool for the risk assessment of OSAS.
