Objective : We analyzed changes in the affected side motor function according to the region and severity of motor paralysis in patients during convalescent rehabilitation. Methods : The subjects recruited were 1,903 hemiplegic patients with primary stroke from a supratentorial unilateral lesion, for which a full-time integrated treatment (FIT) program was implemented. We excluded patients with severe complications, those in whom the stroke recurred or its condition rapidly changed during hospitalization, and those in whom the duration from the onset to admission to our hospital was 61 days or longer. The remaining 1,634 patients served as the study subjects, from among whom we chose 917 patients who had been hospitalized for 8 weeks or longer. The affected side motor function was assessed using 5 motor items of the Stroke Impairment Assessment Set (SIAS) every 2 weeks starting from admission. Results and Conclusion : The affected side motor function significantly improved from admission to a convalescent rehabilitation ward through to week 8 in stroke patients, who were actively engaged in daily routines and had mainly walking and ADL exercise. In addition, improvement was more likely to occur for the lower-limb compared to upper-limb, as well as for the proximal compared to distal motor function. This tendency was more marked for more severe cases of paralyses.

A soundcell is defined as a musical unit of meaning with short period of phrase. The soundcell method (SCM) is a musical procedure that decomposes a musical piece into several soundcells and subsequently recomposes the original music with the soundcells arbitrarily scattered. The present investigation aimed to assess cognitive function in the elderly using the SCM. An electronic system realizing the concept and methodology of the SCM was developed, and SCM examination with the school song “Furusato” as the musical piece was performed on18aged females. Four clinical tests were also carried out before or after the SCM examination to screen cognitive function: Mini-Mental State Examination (MMSE), Kana Pick-out Test, and Trail Making Tests A and B. The performance in the SCM examination was compared with the score in the clinical tests. The scores in all four clinical tests were significantly different between subjects who passed and failed the SCM examination. The individuals who passed the SCM examination were not suspected of dementia on the basis of the MMSE and seemed to execute successfully the Kana Pick-out Test. The number of acts and mean act time in the SCM examination were strongly correlated not only with the total score in the MMSE but also with the scores of the two sub-items: attention/calculation and memory recall. The results suggest that the SCM reflects a subject's short-term and recent memory and provides useful supplementary information for early diagnosis of mild cognitive impairment and Alzheimer’s disease since impairment of memory is frequently observed in the early stage of the diseases. In addition, most subjects enjoyed the SCM examination incorporating the element of musical amusement. The SCM is thus expected to allow repetitive and participatory assessment of cognitive function without imposing a large psychological burden on the subject.

There are no signs of a drop in the number of deaths in accidents while at farmwork, hovering around 400 a year. Furthermore, the fact remains that accurate data about those farm accidents are not fully grasped.This reality gave birth to a Special Study Team on the Prevention of Farmwork Accidents in the Japanese Association of Rural Medicine.To cast light on the actuality of farm work accidents, questionnaires on accidents caused by farm machinery and instruments were sent to three medical institutions affiliated with the Association from October 2002 to March 2004. As a result, clinical data were collected on 141 clinical cases. Moreover, studies were performed on five cases in which rescue squads were dispatched to give aid to the injured.The data thus collected on the clinical cases revealed that grass cutters, harvesters, riding and push-on-foot types of tractors, and straw cutters were responsible for many accidents. Some individuals were involved in the accidents as operators of grass cutters were unaware of their existence nearby because of noise from the machines, some dragged in by the harvesters or straw cutters, and some pinned under the tractors.Case studies on death-induced accidents suggested the indispensability of fitting a safety frame and a seat belt to the tractor and installing a cabin on the speed sprayer.For the prevention of accidents by farm machinery, it is important to hold lecture meetings more frequently both on the basic method of their use and on first aid.

We report a case of chronic DeBakey type I dissecting aneurysm with an aberrant right subclavian artery, in which replacement of the ascending aorta and the transverse aortic arch was performed under selective cerebral perfusion, resulting in complete obliteration of the false channel in the descending thoracic aorta. A 57-year-old female was admitted to our service complaining of chest and back pain. An aberrant right subclavian artery that originated from the descending thoracic aorta was identified. During operation, the dissected aortic wall of the aortic arch and the proximal descending thoracic aorta that involved more than half of its circumference was resected, the dissected intima was reapproximated at the distal stump, and the beveled distal end of the tubular ascending aortic prosthesis was secured to the cut edge. The postoperative course was uneventful, and she is leading a normal life now four years after surgery. It is rare to reconstruct the aortic arch for aortic dissection that occurred in a patient with aberrant right subclavian artery, and the technical details were reported.

A 74-year-old woman was admitted to our hospital with a diagnosis of a pseudoaneurysm 5 months after graft replacement of the ascending aorta, and underwent re-replacement employing left ventricle venting through a left anterior thoracotomy. Culture of the thrombi in the pseudoaneurysm revealed Psuedomonas infection. On the 11th postoerative day, a single-stage procedure of irrigation, debridment, and immediate closure with omental transposition was performed. Although the chest CT scan 1 month after the omental transposition revealed a residual abcess, it was completely obliterated after 2 months without further operation.

Anomalous origin of the coronary artery is rare. Various complications have been reported in patients with this anomaly undergoing heart valve surgery. We describe a case of aortic valve stenosis combined with an anomalous origin of the left coronary artery. An 84-year-old man with exertional dyspnea was referred for surgical treatment of severe aortic valve stenosis. Coronary angiography and computed tomography of the coronary artery revealed a coronary arterial anomaly : the left anterior descending coronary artery originated as a branch of the right coronary artery, and the left circumflex artery separately originated from the right coronary sinus and extended behind the aortic annulus. To prevent injury to the anomalous circumflex artery during surgery, the artery was separated from the fatty tissue around the aortic annulus and dissected free from the aortic wall before the performance of transverse aortotomy. The coronary artery exhibited a single orifice that was significantly enlarged. Whether antegrade infusion of the cardioplegic solution could be achieved was difficult to determine. To perform the retrograde infusion, the catheter tip was inserted directly into the coronary sinus from the epicardium because the orifice in the right atrium was lattice-like. Aortic valve replacement was successfully performed with supra-annular prosthesis insertion using a 19-mm Mosaic porcine valve (Medtronic, Minneapolis, MN, USA). The postoperative course was uneventful. When aortic valve replacement is performed for patients with an anomalous coronary artery, careful performance of operative procedures and postoperative observation are considered important for the prevention of specific perioperative complications, such as intraoperative coronary injury or postoperative myocardial ischemic events in patients with an anomalous left circumflex artery.

This case report outlines a clinically undetected urinary bladder plasmacytoid urothelial carcinoma (PUC) with multiple metastases detected at autopsy. An 89-year-old man presented with edema in the lower limbs. Pleural fluid cytology revealed discohesive carcinomatous cells, although imaging studies failed to identify the primary site of tumor. The patient died of respiratory failure. Autopsy disclosed a prostate tumor and diffusely thickened urinary bladder and rectum without distinct tumorous lesions. Histologically, the tumor consisted of acinar-type prostate adenocarcinoma with no signs of metastasis. Additionally, small, plasmacytoid tumor cells were observed in the urinary bladder/rectum as isolated or small clustering fashions. These metastasized to the lungs, intestine, generalized lymph nodes in a non-mass-forming manner. Combined with immunohistochemical studies, these tumor cells were diagnosed PUC derived from the urinary bladder. Both clinicians and pathologists should recognize PUC as an aggressive histological variant, which can represent a rapid systemic progression without mass-forming lesions.

Background/Aims:
Detailed evaluations of overlapping constipation and gastroesophageal reflux disease (GERD) have not been conducted in Japan. The REACTION-J2 study examined the overlap of these diseases in Japan.
Methods:
This internet-based survey recruited participants from general public survey panels. Questions included demographic and medical data and assessments based on validated measures for constipation and GERD. Associations between background factors affecting constipation/GERD overlap, disease measures, and treatment were also evaluated.
Results:
Among 10 000 survey responses received, functional constipation (Rome IV diagnostic criteria) was reported by 439 participants; chronic constipation (Japanese guidelines) by 3804 participants; and subjective constipation symptoms by 2563 participants. The number of participants with constipation/GERD overlap ranged from 73 to 1533 depending on the criteria used. Regardless of the definition used, all GERD groups had significantly higher odds of being constipated than non-GERD participants: the OR (95% CI) for all 9 combinations of definitions ranged between 1.56 (1.21, 2.01) and 2.67 (2.44, 2.92) (all P ≤ 0.001). Straining, hard stools, and sensations of incomplete evacuation and anorectal obstruction/blockage, according to chronic constipation criteria, were common.Participants with constipation/GERD overlap had poorer quality of life (P < 0.001) and worse GERD symptom scores (P < 0.001). The frequency of abnormal stools was highest (P < 0.001) in the constipation/GERD overlap group. In the overlap group, 52.4% and 26.0% used gastric and constipation medication, respectively.
Conclusion
Individuals with constipation/GERD overlap tend to have worsened symptoms and quality of life.

BACKGROUND/AIMS: Despite improvements in endoscopic hemostasis and pharmacological therapies, upper gastrointestinal (UGI) ulcers repeatedly bleed in 10% to 20% of patients, and those without early endoscopic reintervention or definitive surgery might be at a high risk for mortality. This study aimed to identify the risk factors for intractability to initial endoscopic hemostasis. METHODS: We analyzed intractability among 428 patients who underwent emergency endoscopy for bleeding UGI ulcers within 24 hours of arrival at the hospital. RESULTS: Durable hemostasis was achieved in 354 patients by using initial endoscopic procedures. Sixty-nine patients with Forrest types Ia, Ib, IIa, and IIb at the second-look endoscopy were considered intractable to the initial endoscopic hemostasis. Multivariate analysis indicated that age > or =70 years (odds ratio [OR], 2.06; 95% confidence interval [CI], 1.07 to 4.03), shock on admission (OR, 5.26; 95% CI, 2.43 to 11.6), hemoglobin <8.0 mg/dL (OR, 2.80; 95% CI, 1.39 to 5.91), serum albumin <3.3 g/dL (OR, 2.23; 95% CI, 1.07 to 4.89), exposed vessels with a diameter of > or =2 mm on the bottom of ulcers (OR, 4.38; 95% CI, 1.25 to 7.01), and Forrest type Ia and Ib (OR, 2.21; 95% CI, 1.33 to 3.00) predicted intractable endoscopic hemostasis. CONCLUSIONS: Various factors contribute to intractable endoscopic hemostasis. Careful observation after endoscopic hemostasis is important for patients at a high risk for incomplete hemostasis.
