Successful treatment of ischemic stroke associated with brachiocephalic artery stenosis using alteplase / Journal of Rural Medicine

Introduction: Brachiocephalic artery stenosis rarely causes right hemispheric infarction with associated left hemiparesis. To date, there have been no reported cases of stroke associated with brachiocephalic artery stenosis that were successfully treated with recombinant tissue-type plasminogen activator (rt-PA), alteplase.Case Report: An 80-year-old woman presented with left hemiparesis. Brain computed tomography showed no hemorrhage, and computed tomography angiography demonstrated brachiocephalic artery stenosis. Alteplase was administered based on a diagnosis of ischemic stroke. Brain magnetic resonance imaging showed multiple acute infarctions. Thereafter, the blood pressure of the right arm was found to be lower than that of the left arm. The patient’s neurological deficits gradually improved; she was eventually able to walk again and was thus discharged home.Conclusion: While the combination of left hemiparesis and a decrease in blood pressure in the right arm are well known in patients with stroke associated with Stanford type A aortic dissections, it may also occur in patients with stroke due to brachiocephalic artery stenosis. Unlike stroke associated with Stanford type A aortic dissections, stroke due to brachiocephalic artery stenosis may be treated with alteplase.

Serial Changes in Score on the Japanese Version of the Trail Making Test (TMT-J) After Minor Ischemic Stroke / 日本農村医学会雑誌

The Trail Making Test (TMT) is a widely used measure of attention impairment. The time needed to complete the TMT (TMT score) is longer with greater impairment of attention in patients with brain diseases. TMT score becomes large in a proportion of patients with minor ischemic stroke. The Japanese version of the TMT- (TMT-J) was published in 2019. The purpose of this study was to clarify serial changes in TMT-J scores in patients with minor ischemic stroke. We retrospectively reviewed the TMT-J scores in those patients who completed the test both 8-14 days and 29-35 days after stroke onset. On initial evaluation, 1 of 21 patients could not complete TMT-J Part A. TMT-J Part A scores had a mean of 67 s and were abnormally large in 45% of the 20 patients who completed this part. Two of these 20 patients could not complete TMT-J Part B. TMT-J Part B scores had a mean of 135 s and were abnormally large in 61% of the 18 patients who completed this part. On second evaluation, scores on Part A and Part B improved in 76% and 73% of patients, respectively. This study demonstrated that abnormal TMT-J scores 8-14 days after onset of minor ischemic stroke improved over time in most patients.

Practical guide to choosing dabigatran 150 mg twice daily or apixaban 5 mg twice daily for patients with atrial fibrillation / Journal of Rural Medicine

Based on previous reports, we propose a practical guide to choose dabigatran 150 mg twice daily or apixaban 5 mg twice daily for patients with atrial fibrillation. We recommend the use of dabigatran 150 mg twice daily for patients with atrial fibrillation who have a high risk of embolism (e.g., ischemic stroke on other oral anticoagulants, presence of left atrial appendage thrombus) and a low risk of bleeding. However, the prevalence of such patients with atrial fibrillation is considered low because patients with atrial fibrillation with a high risk of embolism usually have a high risk of bleeding. In most other patients with atrial fibrillation, the use of apixaban 5 mg twice daily should be considered.

Acute pancreatitis is a very rare comorbidity of acute ischemic stroke / Journal of Rural Medicine

Background: Although acute pancreatitis is listed among the exclusion criteria for the administration of recombinant tissue plasminogen activator according to the Japanese Guideline for the Management of Stroke, the co-occurrence of acute pancreatitis and acute ischemic stroke has not been investigated. The present study aimed to assess the incidence rate of acute pancreatitis in patients with acute ischemic stroke.Methods: This study consecutively enrolled all patients with ischemic stroke admitted to the Department of Neurology, JA Toride Medical Center between April 2014 and March 2016. Diagnosis of acute pancreatitis was made according to the revised Atlanta Classification of Acute Pancreatitis. We retrospectively analyzed serum amylase activity and the frequency of acute pancreatitis as a comorbidity of ischemic stroke.Results: A total of 411 ischemic stroke patients were included. Serum amylase activity was measured for 364 patients, 27 of whom presented with amylase activity exceeding the upper limit of normal. In two patients with serum amylase activity greater than three times-fold the upper limit of normal, computed tomography or transabdominal ultrasonography showed no characteristic findings of acute pancreatitis. No patient in the cohort met the diagnostic criteria for acute pancreatitis.Conclusions: Acute pancreatitis is a very rare comorbidity of acute ischemic stroke.

Clinical Features and Treatment of Patients With Essential Thrombocythemia / 日本農村医学会雑誌

We summarized recent findings regarding the clinical features and treatment of patients with essential thrombocythemia (ET), in particular, those with calreticulin (CALR ) mutations. CALR mutations are frameshift mutations of exon 9, which are mainly composed of a 52-bp deletion (Type 1) or 5-bp insertion (Type 2). ET with CALR mutations is associated with younger age, male sex, higher platelet count, lower hemoglobin level, lower leukocyte count, and lower incidence of thrombosis compared with ET with Janus kinase 2 (JAK2 ) mutations. There is no transformation to polycythemia vera in ET patients with CALR mutations. Patients with ET who have CALR type 1 mutations are at higher risk of thrombosis and myelofibrotic transformation compared with ET with CALR type-2 mutations. The standard treatment of CALR-mutated ET patients is currently based on the treatment algorithm of JAK2-unmutated ET patients. Further studies are necessary to clarify whether the appropriate treatment differs between type 1 and 2 mutations of CALR-mutated ET patients.

Perspectives concerning living wills in medical staff of a main regional hospital in Japan / Journal of Rural Medicine

<b>Objective:</b> Living wills, written types of advanced directives, are now widespread in western countries, but in Japan, their recognition still remains restricted to a small part of the population. As an initial step to introduction of such patient-oriented medicine, we surveyed present recognition and acceptance patterns concerning living wills in a main regional hospital located in a suburban area of Tokyo.<br><b>Methods:</b> Without any preceding guidance on living wills, the questionnaire on living wills was distributed to all the staff working at JA Toride Medical Center in September 2013, and their responses were collected for analysis within one month.<br><b>Results:</b> Questionnaires were distributed to all hospital staff, 843 in total, and 674 responses (80.0% of distributed) were obtained. The term of living will was known by 304 (45.1%) of the respondents, and introduction of living wills to patients was accepted in 373 (55.3%) of the respondents, meanwhile, 286 (42.4%) respondents did not indicate their attitude toward living wills. As to styles of document form, 332 respondents (49.3%) supported selection of wanted or unwanted medical treatments and care from a prepared list, and 102 respondents (15.1%) supported description of living wills in free form. As preferred treatment options that should be provided as a checklist, cardiac massage (chest compression) and a ventilator were selected by more than half of the respondents. Based on their responses, we developed an original type of living wills available to patients visiting the hospital.<br><b>Conclusions:</b> Although not all the respondents were aware of living wills even in this main regional hospital, introduction of living wills to patients was accepted by many of the hospital staff. Awareness programs or information campaigns are needed to introduce living wills to support patient-centered medicine.

Problems With Medical Gas Fitting in Great Earthquake Disaster / 日本農村医学会雑誌

  The water supply system in our hospital was disabled as its elevated water tank was badly damaged by the earthquake that hit northeast Japan on March11, 2011. Subsequently, the dysfunction of suction equipment of a water seal type threw the whole hospital into utter confusion, though temporarily. We realized that injection of some degree of water could recover the suction system on manual. To minimize the damage from a natural disaster and strengthen the hospital ability for all contingencies, we have decided to employ the oil rotary type rather than the water seal type in the system of suction equipment.

Creating Flowcharts of Eating and Swallowing / 日本農村医学会雑誌

Purpose: To create flow charts of eating and swallowing that make it easy to identify the cases requiring professional treatment including dysphagia rehabilitation during oral intake.Subjects: 28 patients (mean age: 78.7±11.3 years) with dysphagia who underwent videofluorography (hereinafter “VF”).Methods: We conducted various tests such as Repetitive Salvia Swallowing Test (RSST), Modified Water Swallowing Test (MWST) and Food Test (FT), and studied relationships between VF findings and Fujishima's grade of eating and swallowing capability.Results: After the examination of th results of RSST (sensitivity: 0.83, specificity: 0.22), MWST (sensitivity: 0.56, specificity: 0.72), FT (sensitivity: 0.33, specificity: 0.75), VF and grade of eating and swallowing capability of Fujishima, the use of MWST and FT was appropriate. However, four cases in which the results of MWST and FT were over the cut-off value had misswallowed water and food. We created the flowcharts considering that all of those 4 cases are also the cases that suffered from the consequences of cerebral strokes.

Effects of Ambient Changes on ADLs of Patients As Assessed by Use of Barthel Index--In the Cases of Stroke and Femoral Neck Fracture Patients-- / 日本農村医学会雑誌

  When subacute elderly patients are transferred from an acute hospital to a rehabilitation facility, the likelihood is that the environmental change will decrease the patients' ability to perform the basic activities of daily living (ADLs). In this study, we assessed the effects of the ambient changes on ADLs by the use of the Barthel Index, the reliability as well as validity of which is rated high for assessing the patient's fundamental ability. Our subjects consisted of the patients with hemiplegia who had undergone medical treatment of stroke and those who had been operated on for femoral neck fracture (FNF) in Toride Kyodo General Hospital. They were transferred to the convalescent rehabilitation ward (CRW) of Aida Memorial Rehabilitation Hospital, affiliated with our hospital. We compared the BI scores given to the patients by physical, occupational and speech therapists, when discharged from our hospital, and those scores given by nurses within one week after the patients moved to the CRW. Differences between BI scores given at Toride Hospital and those at the rehabilitation hospital averaged -5.9±16.0 points for stroke patients and -7.3±14.1 pointsfor FNF patients. Spearman's rank correlation coefficient of BI scores in the acute hospital and in the CRW for stroke patients was 0.91 (p<0.001) and 0.69 (p<0.001) for FNF. There was no significant difference in changes in BI scores between stroke and FNF. However, there was a tendency for the patients' functional ability in daily living to be assessed lower in the FNF patients than in the stroke patients. This was probably because the former were older than the latter on the average. The average age of the FNF patients was 81.4 years and that of the stroke patients was 68.5 years.

Success in Energy Consumption in our Hospital / 日本農村医学会雑誌

A reduction in electricity and heating expenses is a major consideration with every hospital in Japan. In our hospital, all the personnel including the members of the facilities division have joined forces to mount the “1,300kW campaign” aimed at cutting down on the amount of maximum instantaneous electric power consumption (demand) from 1,500kW to 1,300kW in one year, and succeeded in curtailing heating and lighting expenses by well over 4 million yen. The key to success was how to control the amount of demand. The cooperation of all the personnel of the hospital was vital. Therefore, it was important to raise the awareness of all the personnel concerning energy conservation. We thought that setting the concrete numerical target “from 1,500kW to 1,300kW” was effective. It is no exaggeration that such a cutback in energy consumption contributes not only to the management of a medical institution but also to the environmental preservation on a global scale. Finally, the medical institutions should put contribution to the community into the basic principles at the time when environmental preservation (ecology), energy consumption reduction, risk management and catastrophic disaster etc. have become topics of conversation.

Marchiafava-Bignami disease with only slowly progressive cognitive impairment / Journal of Rural Medicine

We report on a right-handed 43-year-old policeman with atypical Marchiafava-Bignami disease (MBD). The typical clinical manifestations of MBD are reduced consciousness, confusion, seizures, psychotic and emotional symptoms, hemiparesis, dysarthria, ataxia, and coma and death. However, our patient had not developed any of the above symptoms except for slowly progressive cognitive impairment mimicking that of Alzheimer disease. The incidence of MBD may be higher and its prognosis less severe than generally believed. MBD has been underdiagnosed and underreported, and nonspecific general symptoms and encephalopathy in an alcoholic might indicate undiagnosed MBD.

Atypical Miller Fisher syndrome with complete bilateral ophthalmoplegia mimicking brainstem stroke / Journal of Rural Medicine

We report on three elderly patients with stroke-like onset of atypical Miller Fisher syndrome (MFS). The serum titer of anti-GQ1b IgG was markedly elevated in these patients. Their prognoses were sufficiently good with immunoadsorption therapy with or without intravenous immune globulin (IVIg) therapy. However, some neurological findings were not characteristic of typical MFS. Patient 1 suffered from prolonged dysesthesia in her left extremities, and Patients 2 and 3 showed no ataxia. Moreover, complete bilateral gaze limitation is rare in MFS. The sudden stroke-like onset along with the gaze limitation of these patients suggests that the unexpected elevation in the serum titer of anti-GQ1b IgG due to unknown immune dysregulation might have severely affected the third, fourth, and sixth nerves and this potent antibody rapidly attacked these nerves and induced stroke-like clinical features and complete ophthalmoplegia.

Burdens to Family Members in Home Care and Related QOL Factors / 日本農村医学会雑誌

This study was conducted to shed light on the actual conditions of home care and quality-of-life factors related to the burdens on families. For this purpose, a survey was carried out on main caretakers in the families who were using our home care support service. Fundamental information about the main caretakers and those who need care were garnered. In addition, WHO/QOL-26 and burdens for main caretakers were checked up on.The survey found that those who have looked after the sick or invalid for less than six months and those over five years keenly felt that they were shouldering a heavy burden. With the progression of dementia, the caretakers increasingly felt the burden getting heavier. Physical factors in QOL were linked to the burden which caretakers feel has to be borne, but psychological and social factors were not. This finding might have been ascribed to the fact that the persons surveyed were residents of the provincial city, part of which is rural. They were mostly old women and must have gained the support of their relatives. It is easy to assume that their role perception and sense of responsibility together with regional characteristics were reflected in psychological and social QOL factors.

False-negative and False-positive Diffusion-weighted MR Findings in Acute Ischemic Stroke and Stroke-like Episodes / Journal of Rural Medicine

Background: Diffusion-weighted magnetic resonance (MR) imaging (DWI) is an excellent examination for detecting acute ischemic stroke, but false-negative cases have been reported recently.Patients and Methods: Since the present MR scanner (1.5-T, Siemens Symphony) was introduced to our hospital, a prospective study was designed in the Departments of Neurology and Radiology to evaluate the DWI findings in patients tentatively diagnosed to have an acute infarction and in those with stroke-like episodes. During the 31 months between June 2000 and December 2002, 572 consecutive patients with acute cerebral infarction or presenting conditions mimicking ischemic stroke, including transient ischemic attack (TIA), sudden-onset isolated vertigo, and loss of consciousness (LOC) with or without seizure, underwent DWI.Results: Four of 366 patients with a cerebral infarction (1.1%) had false-negative DWI in the acute stage, and 10 of 206 patients with conditions mimicking ischemic stroke (4.9%) had false-positive DWI in the acute stage. Of these 10 patients, there were five cases with TIA, four with sudden-onset isolated vertigo, and 1 with LOC with seizure. Sensitivity and specificity values were 98.9% and 97.6%, respectively, when DWIs were performed to diagnose acute cerebral infarction.Conclusion: DWI rarely fails to detect an acute-stage cerebral infarction, but further confirmatory measures may be necessary when there is a negative examination using a clinical or computed tomographic diagnosis to the contrary.

Moyamoya-like Phenomenon in Middle and Anterior Cerebral Artery Occlusions in the Elderly / 日本農村医学会雑誌

We present here five cases of moyamoya disease-like phenomenon in the elderly patients who had moyamoya vessels in the basal ganglia as a sequela of occlusion of middle cerebral artery (MCA) and/ or anterior cerebral artery (ACA). Ages ranged from 59 to 77 years (mean age: 67.6). Clinical manifestations included transient ischemic attacks (TIAs), reversible ischemic neurological deficits (RINDs) and mild hemiparesis. All the patients were living normal daily lives despite recurrent cerebral ischemic attacks. They had some risks of cerebrovascular disease, such as hypertension, and hyperlipemia. Angiography showed either MCA or ACA occlusion or both. Retrograde leptomeningeal filling of the ischemic region was maintained by the posterior cerebral artery (PCA) and ACA. Obstruction of the intracranial internal carotid artery was not visible. These neuroradiologic findings were not consistent with the criteria for moyamoya disease. The present cases may be related to congenital or acquired abnormalities in the main trunks of cerebral arteries.

The Role of Percutaneous Endoscopic gastrostomy for the Enteral Nutrition / 日本農村医学会雑誌

We report our experience with percutaneous endoscopic gastrostomy (PEG) to assess the safety and usefulness of the PEG. We reviewed 21 cases (mean age, 72 years), including 20 patients with neurological impairment and one patient with cancer of the stomach.<BR>Though two minor complications (wound infection and bleeding from the stomach) occurred, wound infection healed with antibiotics and bleeding stopped spontaneously. Six of these patients died (3 died from pneumonia, 2 from respiratory failure, and 1 from stomach cancer), but there were no PEG-related deaths. After PEG procedure, serum protein, albumin and cholesterol improved significantly. PEG was not only safe but also effective for the nutritional support and the 4-year survival rate was 56%. By this method, moreover, half of the patients could leave hospital and return home.<BR>In conclusion, PEG, is thought to be the procedure of choice for the long-term enteral nutrition.
