A 71-year-old man was given a diagnosis of saccular aneurysm of the aortic arch (maximum 48mm in diameter) at the age of 68. When he was 69 years old, he began to take steroids for autoimmune hepatitis (AIH). The following year, the aneurysm was enlarged to 52mm. Further examinations showed the aneurysm to extend to the ostium of the left subclavian artery. Since he had transient ischemic attacks, ultrasonography of the carotid arteries was performed. Bilateral internal carotid stenoses were detected, however, cold Xe CT showed an almost normal pattern of cerebral blood flow. We decided that operation was feasible using retrograde cerebral perfusion (RCP). Liver dysfunction due to AIH improved, and his steroid dosage was tapered. Using RCP, the no-touch technique and the elephant trunk procedure, he underwent the replacement of ascending aorta and aortic arch and was discharged without major complications. RCP and the no-touch technique might enable safer operations on patients with carotid stenoses.

Purpose: The aim of this study was to evaluate the short-term outcome of physiotherapy in patients with acetabular labral tears and to assess the effectiveness of physiotherapy according to the severity of the labral tear. Materials and Methods: Thirty-five patients who underwent physiotherapy for treatment of symptomatic acetabular labral tears were enrolled. We evaluated the severity of the acetabular labral tears, which were classified based on the Czerny classification system using 3-T MRI. Clinical findings of microinstability and extraarticular pathologies of the hip joint were also examined. The International Hip Outcome Tool 12 (iHOT12) was use for evaluation of outcome scores pre- and post-intervention. Results: The mean iHOT12 score showed significant improvement from 44.0 to 73.6 in 4.7 months. Compared with pre-intervention scores, significantly higher post-intervention iHOT12 scores were observed for Czerny stages I and II tears (all P<0.01). However, no significant difference was observed between pre-intervention and post-intervention iHOT12 scores for stage III tears (P=0.061). In addition, seven patients (20.0%) had positive microinstability findings and 22 patients (62.9%) had findings of extra-articular pathologies. Of the 35 patients, eight patients (22.9%) underwent surgical treatment after failure of conservative management; four of these patients had Czerny stage III tears. Conclusion The iHOT12 score of patients with acetabular labral tears was significantly improved by physiotherapy in the short-term period. Improvement of the clinical score by physiotherapy may be poor in patients with severe acetabular labral tears. Determining the severity of acetabular labral tears can be useful in determining treatment strategies.

STUDY DESIGN: A retrospective study. PURPOSE: To examine the effectiveness of using an electrodiagnostic technique as a new approach in the clinical diagnosis of extraforaminal stenosis at L5-S1. OVERVIEW OF LITERATURE: We introduced a new effective approach to the diagnosis of extraforaminal stenosis at the lumbosacral junction using the existing electrophysiological evaluation technique. METHODS: A consecutive series of 124 patients with fifth lumbar radiculopathy were enrolled, comprising a group of 74 patients with spinal canal stenosis and a second group of 50 patients with extraforaminal stenosis at L5-S1. The technique involved inserting a pair of needle electrodes into the foraminal exit zone of the fifth lumbar spinal nerves, which were used to provide electrical stimulation. The compound muscle action potentials from each of the tibialis anterior muscles were recorded. RESULTS: The distal motor latency (DML) of the potentials ranged from 11.2 to 24.6 milliseconds in patients with extraforaminal stenosis. In contrast, the DML in patients with spinal canal stenosis ranged from 10.0 to 17.2 milliseconds. After comparing the DML of each of the 2 groups and at the same time comparing the differences in DML between the affected and unaffected side of each patient, we concluded there were statistically significant differences (p<0.01) between the 2 groups. Using receiver operating characteristic curve analysis, the cutoff values were calculated to be 15.2 milliseconds and 1.1 milliseconds, respectively. CONCLUSIONS: This approach using a means of DML measurement enables us to identify and localize lesions, which offers an advantage in diagnosing extraforaminal stenosis at L5-S1.

The efect of some types of exercise on systolic pressure was studied. The results were as follows.
1. Increased rate of systolic pressure immediately after run of eight distances was greatest in 100 meter run. Such a high level was also observed in both 400 and 1, 500 meter runs.
Further prolongation of the distance, however, induced a sharp reduction of increased rate to 5, 000 meters and in a run of still longer distance the above tendency was weakened.
2. If these results are applicable to the change of systolic pressure during a prolonged exercise, Edward's graphic representation seems to be true. Some of our experiments, however, indicated that Edward's curve was not the only case.
Some features often expected were the following.
a) Generally, the final rise was low if the initial rise was low.
b) However, the final rise would be high in the cases with a faster finish even if the initial rise was low.
c) In general, the final rise was high if the initial rise was high.
d) However, the final rise would be lowering as development of exhaustion even if the initial rise was high, and only this form was considered to analogize with Edward's curve.
3. Blood pressure was determined during short interruption of exercise in 10, 000meter run. The lap time was estimated immediately before the determination of pressure.
Since there was a strong statistical correlation between the increased rate of systolic pressure and the lap time (r=0.698, P<0.01), the fall in systolic pressure increased at early stage in a long continued exercise was supposed to be induced by decreased pace.
Therefore, decreased severity of exercise may be a major factor inhibiting increase of pressure during prolonged exercise. It is undeniable that this type brought about by in-hibiting pressor effect is angmented by some nervous or humoral factors.
4. The longer the distance, the earlier the subnormal phase after exercise tends to start and the deeper the drop of systolic pressure will become.
In all of the four prolonged runs over 5, 000 meters was observed average drop below normal of about 20 per cent and the lowest value of 28 per cent except two cases indicating marked fall. Futhermore, average fall below normal in mean arterial pressure induced after increased pressure by epinephrine was 30 per cent in rabbits. These data showed that in subnormal phase there may be a certain lower limit to sink and that the existense of this protective line of defence would prevent deterioration of the circulation.
5. The systolic pressure rised in the trained higher than in the untrained immediately after a short and sharp effort, but in the former the reduction of the rise with longer distance of run was more slight than the latter.

Objective:Delayed gastric emptying (DGE) after pylorus-preserving pancreatoduodenectomy (PpPD) is a persistent and frustrating complication. To preserve pylorus ring with denervation and devascularization may be a risk factor of DGE after pancreaticoduodenectomy. We conducted this study to confirm the hypothesis that pylorus-resecting pancreatoduodenectomy (PrPD) reduces the incidence of DGE compared to PpPD. Moreover, long-term outcomes of PrPD and the adverse effect of postsurgical DGE on long-term outcomes have not been reported. Therefore, in addition, this study focused on long-term outcomes during 24 months after surgery between PrPD versus PpPD. Methods: Between October 2005 and March 2009, at Wakayama Medical University Hospital (WMUH), 130 patients with pancreatic or periampullary lesions were randomized to preservation of the pylorus ring (PpPD) or to resection of the pylorus ring (PrPD). In PpPD, the proximal duodenum was divided 3-4cm distal to the pylorus ring. In PrPD, the stomach was divided just adjacent the pylorus ring and the nearly total stomach more than 95% was preserved. Shortterm and long-term outcomes were evaluated between PpPD and PrPD. Primary endpoint is the incidence of DGE. DGE was defined according to a consensus definition and clinical grading about postoperative DGE proposed by the international study group of pancreatic surgery (ISGPS). This RCT was registered at Clinical Trials.Gov NCT00639314. Results: Of 130 patients who were enrolled in this study, 64 patients were randomized to PpPD and 66 to PrPD. The overall incidence of DGE in this RCT was 10.8% (14 of 130 patients); the overall incidence of DGE was significantly lower in PrPD (4.5%) than PpPD (17.2%) (P =0 .0244). DGE was classified into three categories proposed by the International Study Group of Pancreatic Surgery. The proposed clinical grading classified 11 cases of DGE in PpPD into grades A (n=6), B (n=5), and C (n=0), and one case in PrPD into each of the three grades. In long-term outcomes, weight loss > grade 2 (Common Terminology Criteria for Adverse Events, Ver. 4.0) at 24 months after surgery improved significantly in PrPD (16.2%) compared with PpPD (42.2%) (P = 0.011). Nutritional status and late postoperative complications were similar between PpPD and PrPD. The incidence of weight loss greater than Grade 2 at 24 months after surgery was 63.6% in patients with DGE group and 25.3% in patients without DGE group (P = 0.010). Tmax (the time to peak 13CO2 content in 13C-acetate breath test) at 24 months after surgery in patients with DGE was significantly delayed compared with those without DGE (27.9 ± 22.7min vs.16.5 ± 10.1min, P=0.023). Serum albumin at 24 months after surgery was higher in patients without DGE than those with DGE (3.7±0.6 g/dl vs. 4.1±0.4 g/dl, P=0.013). Conclusion: This study clarified that PrPD can lead to a significant reduction in the incidence of DGE compared with PpPD. Moreover, PrPD offers similar longterm outcomes with PpPD. DGE may be associated with weight loss and poor nutritional status in long-term outcomes.

From January 1981 through December 1986, 27, 513 individuals consisting of 17, 918 males and 9, 595 females underwent health examinations at Health Care Center in Obihiro Kosei Hospital. 14.2% of healthy and asymptomatic men and 29.1% of healthy and asymptomatic women had microscopic hematuria (one or more RBCs per HPF).
To evaluate the clinical significance of microhematuria, about one third of patients with asymptomatic microhematuria who had undergone complete urological examination were reviewed.
Genitourinary neoplasms were found in 0.21%(8 bladder cancers, 2 prostatic cancers and 1 renal cell cancer). The incidence of cancers increases proportionate to increase in age, furthermore, lesions were found more commonly in men than in women. We could find no relationship between the degree of hematuria and the cause. The results suggest that patients with asymptomatic microhematuria should undergo urological examinations.

BACKGROUND/AIMS: Recent genome-wide analyses have provided strong evidence concerning adverse events caused by thiopurine drugs such as azathioprine (AZA) and 6-mercaptopurine. The strong associations identified between NUDT15 p.Arg139Cys and thiopurine-induced leukopenia and severe hair loss have been studied and confirmed over the last 2 years. However, other coding variants, including NUDT15 p.Val18_Val19insGlyVal, NUDT15 p.Val18Ile, and FTO p.Ala134Thr, and a noncoding variation in RUNX1 (rs2834826) remain to be examined in detail in this respect. Therefore, we investigated the correlation between these adverse events and the 5 recently identified variants mentioned above among Japanese patients with inflammatory bowel diseases (IBD). METHODS: One hundred sixty thiopurine-treated patients with IBD were enrolled. Genotyping was performed using TaqMan SNP Genotyping Assays or Sanger sequencing. RESULTS: None of the 5 variants were associated with gastrointestinal intolerance to AZA. However, NUDT15 p.Arg139Cys was significantly associated with the interval between initiation and discontinuation of AZA among patients with gastrointestinal intolerance. This variant was strongly associated with early (<8 weeks) and late (≥8 weeks) leukopenia and severe hair loss. Moreover, it correlated with the interval between initiation of thiopurine therapy and leukopenia occurrence, and average thiopurine dose. NUDT15 p.Val18_Val19insGlyVal, NUDT15 p.Val18Ile, FTO p.Ala134Thr, and RUNX1 rs2834826 exhibited no significant relationship with the adverse events examined. CONCLUSIONS: Of the 5 variants investigated, NUDT15 p.Arg139Cys had the strongest impact on thiopurine-induced leukopenia and severe hair loss; therefore, its genotyping should be prioritized over that of other variants in efforts to predict these adverse events in Japanese patients with IBD.

Objective: The Risk Minimization Plan is developed in the Risk Management Plan (RMP), patient information materials are sometimes prepared as Additional Risk Minimization Activities (ARMA). On the other hand, there are many patient information materials that are not prepared as RMP materials, but are prepared independently by pharmaceutical companies and are actually used to provide information to patients. However, there is no detailed report on the differences between them. Therefore, in this report, we investigated for description of Important Identified Risks (IIRs) and Important Potential Risks (IPRs) in patient information materials.Methods: The previously published RMP of 588 drugs were obtained on October 1,2020, and used in analysis. We surveyed the description of IIRs and IPRs in patient information materials, and compared patient information materials based on ARMA in the RMP (patient information materials as RMP materials) and patient information materials developed independently by pharmaceutical companies that are not based on ARMA in the RMP (patient information materials as not RMP materials).Results: Of the 588 drugs, 454 drugs had patient information materials. In addition, 241 drugs had patient information materials as RMP materials. One thousand fifteen of the 1,577 IIRs were listed in the patient information materials as RMP materials (64.4%listing rate). One hundred sixty-six of the 724 IPRs were listed in the patient information materials as RMP materials (22.9%). On the other hand, 700 of the 1,131 IIRs were listed in the patient information materials as not RMP materials (61.9% listing rate). Ninty one of the 447 IPRs were listed in the patient information materials as not RMP materials (20.4%).Conclusion: It was found that there was no difference in the description of IIRs and IPRs between patient information materials as RMP materials and patient information materials as not RMP materials.
