A 46-year-old female patient with non-alcoholic steatohepatitis (NASH) was administered nateglinide, an insulin secretagogue, for 7 months, and then polyenephosphatidylcholine, an anti-oxidant medication, in accordance with the two-step hypothesis of NASH, with insulin resistance as the initial pathogenesis and oxidative stress as the second. HOMA-R, an index of insulin resistance, improved, and hepatic marker levels improved markedly by four weeks after initiation of polyenephosphatidylcholine. The beneficial effects of treatment continued over the 24 months of the study. A liver biopsy evaluated using Brunt's criteria showed improvement from stage 2 to stage 0 after 9 months. These findings suggest the therapeutic efficacy of step by step treatment of NASH in accordance with the two-stage hypothesis.

For diagnosis of prostate cancer, MRI was performed in 91 patients prior to prostate biopsy, and prostate cancer was detected in 37 patients. The ability of MRI diagnosis compared with biopsy was accuracy 0.84, sensitivity 0.95, and specificity 0.76.In 26 patients (14 patients with prostate cancer) from whom MR images were obtained by diffusion weighted imaging, ADC value and PSA value showed a reverse correlation significantly.The ADC value was 0.97±0.23-3mm2/sec in the cancer area, 1.51±0.20-3mm2/sec in the normal peripheral zone, and 1.47±0.12-3mm2/sec in the normal central zone. The ADC value in the cancer area was smaller than that in the normal peripheral area or in the normal central zone significantly (p<0.001).The relation between ADC value and Gleason score did not show any correlation. However, when the Gleason score was under 6, ADC value was 1.11±0.20-3mm2/sec, and when it was over 7, ADC value was 0.81±0.19-3mm2/sec which showed a lower value than the ADC value with Gleason score under 6 significantly (p<0.05).MRI was effective for visualization of prostate cancer. We concluded that pre-biopsy MRI in prostate cancer would allow not only systemic-biopsy but also accurate targeting-biopsy, and it would improve the diagnosric ability of biopsy.

A 73-year-old man visited our hospital with complaints of fever, epigastric painand jaundice. Laboratory examinations showed elevation of GOT, GPT, ALP, LAP and amylase. Abdominal ultrasonography revealed gall bladder stones. Endoscopic findings showed parapapillary diverticulum, but the common bile duct stone was not revealed by endoscopic retrograde cholangiography. He was conservatively treated and then discharged. Two months after, the patient was readmitted for cholecystitis and underwent cholecystectomy. After further 2 months, he was again admitted for the same symptoms as those on first admission. We diagnosed this case as Lemmel's syndrome and performed emergency endoscopy. Endoscopic findings revealed the meal rest inside the parapapillary diverticulum. After we removed the meal rest obstructing the orifice of the papilla of Vater using grasping forceps, we performed EST. Purulent bile gushed out from the orifice. Two years have elapsed since them. Cholangitis has not recurred during this period. Therefore, we concluded that EST is effective in treating Lemmel's syndrome.

A survey was carried out on how the To-no District is coping with the need of first aid for patients requiring life-supporting treatment before hospitalization. Although there were cities in this district where statistics on first aid were not available, the survey found that, during the 4-year period from 1994 through 1997, bystander CPR (cardiopulmonary resuscitation) saved 11.2% of the lives of patients with CPA (cardiopulmonary arrest). Incidentally, 11.3% of the population attended CPR courses offered by public institutions. Gifu Prefecture has helicopters for use in rescue work, but the survey found that some cities had not ever sponsored drills using helicopters in life-saving operations. Our findings revealed the indifference of the general public as well as administrators in this district toward emergency care. Public recognition of the importance of the care of suddenly ill or injured patients must be gained. Furthermore, acquisition of skills required for first aid by lay people and technical improvement of these skills in professional rescuers are necessary. The authors think that these are the community educational responsibility of hospitals and other medical institutions.

Purpose:This study investigated the current state of medical care and home palliative care for terminally ill cancer patients in Japan. Methods:We conducted a retrospective questionnaire study of 352 cancer patients who received home palliative care from 6 specialized home care clinics and discontinued home care or died from January to June in 2012. Results:The questionnaire was answered by 290 patients〔165 men(57%), mean age:72±13 years〕who started home palliative care after completing cancer treatment. Home visits from nurses were used by 238 patients(98%)and 95 patients(39%)used home care workers. Within a month before discontinuation of home care or death, 72 patients(30%)received fluid therapy and 127 patients(52%)received strong opioids. The outcome of home palliative care was death at home in 242 patients(83%)and discontinuation of home care in 48 patients(17%). The reason for discontinuation was family physical and mental problems or physical problems of the patient. Conclusion:This study demonstrated the current state of home palliative care by specialized home care clinics.

Objectives:To determine the factors influencing death or the cessation of palliative care in home-based setting among patients with cancer. Methods:We included 352 terminally ill patients with cancer who received home-based palliative care from six specialized palliative care clinics. We reviewed the medical charts when patients died at home or chose to stop home care. Results:A total of 82% of participants died at home, and 18% chose to stop home care. Multiple logistic regression analysis revealed five independent factors that affected cessation of home-based palliative care:patient and informal caregiver preferences for the place of death not to be at home[odds ratio, 10.1(95% Confidential interval, 2.5-40.9)and 51.9(11.9-226.6), respectively]or uncertain preferences[5.0(1.3-19.4), 10.8(2.3-50.5)];anxiety and depression among informal caregiver[4.1(1.2-13.9)];lower frequency of informal care[6.8(2.0-23.4)];and history of admittance to hospital during home care[11.6(4.0-33.9)]. Conclusion:We revealed independent factors influencing death or the cessation of palliative care in home-based settings among patients with cancer. Our findings suggest the importance of providing support for decision making about the place of death and hospital admission, and psychosocial support for informal caregiver to ensure home death consistent with patient preference.

OBJECTIVESTo investigate the prevalence of non-alcoholic fatty liver disease (NAFLD) in children and its relationship to metabolic syndrome, insulin resistance, and waist circumference (WC).
METHODSThis was a population-based cross-sectional, case-control study. Cases were selected among students of a primary and junior high school, respectively, and age- and sex-matched control subjects were selected randomly (ratio of cases to control subject was 37:113).
RESULTSOf the 846 students, aged between 6 and 15 years, enrolled in the study and screened by ultrasonography, 37 children were diagnosed as having NAFLD (score >/= 1). There was a significant sex difference in the prevalence of NAFLD(P = 0.003). The trend test revealed a strong dose-response relationship (P < 0.001) between pediatric NAFLD and the number of the proposed components of pediatric metabolic syndrome in Japan (MetS-JC), such as a clustering of the components of MetS-JC. Additionally, the linear trend of the odds ratios (ORs) with increasing percentile of the homeostasis model assessment-insulin resistance (HOMA-IR) was statistically significant (P < 0.001). However, when WC was added to the logistic model, the ORs were no longer significant, whereas WC turned out to be an independent risk factor for NAFLD regardless of the HOMA-IR index.
CONCLUSIONThe prevalence of NAFLD in children and adolescents is closely related to metabolic syndrome, insulin resistance, and WC.

Japanese Journal of Pharmacoepidemiology 1999;4(2):133-148
Objective : Carvedilol is a non-selective β blocker with an α blocking activity. Since this drug is highly fat-soluble, it can pass through the blood-brain barrier, and thus may induce depression and lower QOL. In the present study, physicians and pharmacists collaborated to evaluate the antihypertension effect of carvedilol and post-administration changes in QOL. Furthermore, the relationship between QOL and antihypertension effect was analyzed.
Design : Self-controlled study.
Patients and Methods : Subjects were outpatients with hypertension above the age of 70 years who visited one of 42 medical institutions in Japan between April 1995 and March 1996. A total of 243 patients were registered, and 10-20 mg of carvedilol was administered once a day for six months. Pharmacists assessed the QOL of these patients by asking 82 questions on three separate occasions : before administration and one and six months after administration. The antihypertensive effect of this drug was investigated in patients in whom all three QOL questionnaires were collected. The main test items were antihypertensive effect, changes in QOL (subjective QOL with a special emphasis on patient psychology), and the relationship between antihypertensive effect and QOL. The antihypertensive effect of this drug was statistically analyzed by a paired t-test, and changes in QOL were statistically analyzed using generalized estimating equations.
Results : All three QOL questionnaires were collected from a total of 146 patients. Their pre-administration systolic blood pressure was 159.6±1.4 mmHg, and diastolic blood pressure 94.0±0.9 mmHg, and their blood pressure decreased significantly one month after the start of administration. This antihypertensive effect of carvedilol persisted, and the systolic and diastolic blood pressure of these patients six months after the start of administration was 141.1±1.2 and 85.2±0.7 mmHg, respectively (significant decreases when compared to pre-administration levels ; both p<0.05).
Subjective QOL improved significantly after carvedilol administration. And, changes were not seen in sexual function. Changes in the five categories of subjective QOL were as follows : psychological stability, disease-induced inconvenience, and independence improved significantly after carvedilol administration, but changes were not seen in gratification or vitality. However, improvements in subjective QOL did not correlate with improvements in blood pressure.
Conclusions : The results of the present study showed that carvedilol improved QOL without negatively affecting sexual function. Subjective QOL reflects the psychological well-being of patients. In the present study, psychological stability, disease-induced inconvenience, and independence improved significantly, but changes were not seen in gratification or vitality. Since β blockers can suppress the central nervous system, they can reduce psychological stability, gratification and vitality. Even though carvedilol is highly fat-soluble, the results of non-clinical studies have shown that it does not suppress the central nervous system as much as propranolol. The results of the present study showed that carvedilol does not strongly suppress the central nervous system of humans. Moreover, significant changes in QOL were not seen between one and six months after the start of administration of carvedilol, suggesting that it is possible to estimate the QOL of patients on antihypertensive therapy after six months of administration by assessing their QOL one month after administration.

STUDY DESIGN: Retrospective case series. PURPOSE: The purpose of this study was to examine changes in the ligamentum flavum thickness and remodeling of the spinal canal after anterior fusion during a 10-year follow-up. OVERVIEW OF LITERATURE: Extreme lateral interbody fusion provides minimally invasive treatment of the lumbar spine; this anterior fusion without direct posterior decompression, so-called indirect decompression, can achieve pain relief. Anterior fusion may restore disc height, stretch the flexure of the ligamentum flavum, and increase the spinal canal diameter. However, changes in the ligamentum flavum thickness and remodeling of the spinal canal after anterior fusion during a long follow-up have not yet been reported. METHODS: We evaluated 10 patients with L4 spondylolisthesis who underwent stand-alone anterior interbody fusion using the iliac crest bone. Magnetic resonance imaging was performed 10 years after surgery. The cross-sectional area (CSA) of the dural sac and the ligamentum flavum at L1–2 to L5–S1 was calculated using a Picture Archiving and Communication System. RESULTS: Spinal fusion with correction loss (average, 4.75 mm anterior slip) was achieved in all patients 10 years postsurgery. The average CSAs of the dural sac and the ligamentum flavum at L1–2 to L5–S1 were 150 mm² and 78 mm², respectively. The average CSA of the ligamentum flavum at L4–5 (30 mm²) (fusion level) was significantly less than that at L1–2 to L3–4 or L5–S1. Although patients had an average anterior slip of 4.75 mm, the average CSA of the dural sac at L4–5 was significantly larger than at the other levels. CONCLUSIONS: Spinal stability induced a lumbar ligamentum flavum change and a sustained remodeling of the spinal canal, which may explain the long-term pain relief after indirect decompression fusion surgery.

STUDY DESIGN: An experimental animal study. PURPOSE: To evaluate effects of anti-vascular endothelial growth factor (VEGF) on the content and distribution of the calcitonin gene-related peptide (CGRP) in the dorsal ganglia in a rat model. OVERVIEW OF LITERATURE: Increased expression of VEGF in degenerative disc disease increases the levels of inflammatory cytokines and nerve ingrowth into the damaged discs. In animal models, increased levels of VEGF can persist for up to 2 weeks after an injury. METHODS: Through abdominal surgery, the dorsal root ganglia (DRG) innervating L5/L6 intervertebral disc were labeled (FluoroGold neurotracer) in 24, 8-week old Sprague Dawley rats. The rats were randomly allocated to three groups of eight rats each. The anti-VEGF group underwent L5/6 intervertebral disc puncture using a 26-gauge needle, intradiscal injection of 33.3 µg of the pegaptanib sodium, a VEGF165 aptamer. The control-puncture group underwent disc puncture and intradiscal injection of 10 µL saline solution, and the sham-surgery group underwent labeling but no disc puncture. Two rats in each group were sacrificed on postoperative days 1, 7, 14, and 28 after surgery. L1–L6 DRGs were harvested, sectioned, and immunostained to detect the content and distribution of CGRP. RESULTS: Compared with the control, the percentage of CGRP-positive cells was lower in the anti-VEGF group (p<0.05; 40.6% and 58.1% on postoperative day 1, 44.3% and 55.4% on day 7, and 42.4% and 59.3% on day 14). The percentage was higher in the control group compared with that of the sham group (p<0.05; sham group, 34.1%, 40.7%, and 33.7% on postoperative days 1, 7, and 14, respectively). CONCLUSIONS: Decreasing CGRP-positive cells using anti-VEGF therapy provides fundamental evidence for a possible therapeutic role of anti-VEGF in patients with discogenic lower back pain.
