A questionnaire survey was conducted on 8,402 members of the Japanese Neurological Society to examine the current status and countermeasures for physician burnout, and 1,261 respondents (15.0%) responded. In this paper, we report the results of a comparison between male and female physicians. There was a significant difference in working and living conditions only for married people. It was confirmed that men work under stricter conditions in terms of working hours, and that the burden on women is heavier in the division of housework. Analysis using the Japanese Burnout Scale revealed no gender differences in overall scores, but as for factors related to burnout, in addition to factors common to both men and women, factors specific to men or women were clarified.

To identify factors associated with burnout among Japanese physician and to use them in future measures, the Japanese Society of Neurology conducted a survey of neurologists on burnout using a web-based questionnaire in October 2019. A total of 1,261 respondents, 15.0% of the 8,402 members, responded to the survey. The mean of the subscales of the Japanese Burnout Scale was 2.86/5 points for emotional exhaustion, 2.21/5 points for depersonalization, and 3.17/5 points for lack of personal accomplishment. In addition, the burnout of our country's neurologists is not related to workloads such as working hours and the number of patients in charge, but also to a decreased meaningfulness and professional accomplishment. Therefore, it is necessary to take comprehensive measures to improve these issues at the individual, hospital, academic and national levels.

We report a 77-year-old woman suffering from dementia with Lewy bodies (DLB) who presented with Hashimoto encephalopathy. The patient began to mistakenly believe that another person was sleeping in her bed from approximately 70 years of age. She began to show symptoms of parkinsonism after 75 years of age. One night, the patient began to exhibit loitering behavior, and made incomprehensible comments while also exhibiting other abnormal behaviors. Clinical examination revealed rigidity and tremor of the limbs, as well as hallucination, abnormal speech and behavior. We first considered DLB. However, serum anti-thyroglobulin levels turned out to be elevated, indicating Hashimoto encephalopathy as well, and treated the patient with steroid pulse therapy. Her mental symptoms subsequently improved, but rigidity and tremor remained. 123 I-ioflupane SPECT demonstrated decreased accumulation in the bilateral caudal basal ganglia. Anti NH 2 -terminal of α-enolase (NAE) antibody in the serum was positive. Therefore, we diagnosed the patient with the rare comorbidity of DLB and Hashimoto encephalopathy, successfully treated with immunotherapy.

We report 2 cases of resectable advanced gastric cancer who achieved pathological complete response by preoperative chemotherapy with S-1 plus weekly low-dose cisplatin (CDDP). S-1 (80 mg/m²)was administered consecutively for 21 days followed by 14 days' rest, with CDDP (25mg/m²) injected on days 1, 8, and 21. Case 1: A man in his 70s diagnosed with cStage III gastric cancer with lymph node metastases received 2 courses of preoperative chemotherapy with S-1 plus weekly low-dose CDDP followed by total gastrectomy with D2 lymph node dissection. Case 2: A man in his 60s diagnosed with cStage III gastric cancer with lymph node metastases received 4 courses of preoperative chemotherapy with S-1 plus weekly low-dose CDDP followed by total gastrectomy with D2 lymph-node dissection. In both cases, postoperative pathological examination revealed no cancer cells in the resected stomach and lymph nodes. The therapeutic effect of preoperative chemotherapy was assessed as Grade 3. With this regimen, we accomplished preoperative chemotherapy successfully without inpatient care. This regimen can be a promising option as preoperative chemotherapy for advanced gastric cancer.

Intestinal polyps are a distinctive feature of Peutz-Jeghers syndrome (PJS). These hamartomas can lead to significant complications such as intussusception or gastrointestinal bleeding which necessitate multiple laparotomies and bowel resections. In an operation for intestinal intussusception, it is preferable to simultaneously resect as many polyps as possible to prevent recurrence of complications caused by intestinal polyps. We report a case of a woman in her twenties with PJS, diagnosed as small intestinal intussusception caused by an intestinal polyp. We performed not only repair of the intussusception but also endoscopic polypectomy without resection of the small intestine. We successfully resected all polyps larger than 10mm from the duodenum to the ascending colon during the operation.

The "8020" objective seems difficult to achieve, but at least 20 teeth are needed based on difficult cases of defective dentition. Our clinical experience shows that at least 18 teeth are needed to keep 4 occlusal supports. If the number of occlusal supports falls below 4, defective dentition may easily deteriorate to more clinically difficult cases. From our long-term experience, patients over 80 years old who still have 20 teeth usually have stabilized occlusal supports, while many cases who have partially lost their occlusal support do not achieve the 8020 goal. Prevention of partial defects of teeth for restoration of caries and active prosthesis for defects are important to achieve the 8020 goal. Furthermore, continuous follow-up and preventive support are important. If continuous clinical correspondence is possible, 8020 may be achievable in about 80% of all cases.

Learning Objectives: (1)Understand images of breast specimens with microcalcifications obtained by use of micro-focus CT. (2)Learn the relationship between mammographic features, pathologic characteristics, and micro-focus CT images. (3)Learn the usefulness of three-dimensional images in understanding of detailed structures and patterns of microcalcifications without cutting the specimen., Abstract: Microcalcifications are one of the important sign for early detection of breast cancer by use of mammography, and has resulted in the detection of nonpalpable cancer. However, it is difficult to distinguish between benign and malignant microcalcifications, thus causing high false-positive rate. Micro-focus CT employs a x-ray tube of a focal spot size less than 10 microns, and has high spatial resolution, thus resulting in more accurate visualization of structures of microcalcifications. We investigated the relationship between micro-focus CT images of breast specimens with microcalcifications, mammographic features and pathologic characteristics. Micro-focus CT imaging was comparable to pathologic images in terms of resolution and contrast. Microcalcifications were more clearly detected in micro-focus CT imaging than specimen radiographs. Three-dimensional imaging on microcalcifications provided a tool for studying the shape and distribution of calcifications. Micro-focus CT for breast imaging was very useful for understanding of structures and patterns of microcalcifications without cutting the specimen.

We report a patient with dentatorubral-pallidoluysian atrophy (DRPLA). She developed normally until the age of 6 month, when she could sit by herself. However, her psychomotor development was subsequently slow with gradual appearance of equilibrium disturbances and involuntary movements such as polymyoclonia and chorea. Her development deteriorated after myoclonic seizures developed at 4.5 years of age. Electroencephalograms showed semi-continuous bursts of diffuse irregular spike-wave complexes and MRI of the brain showed atrophy of the cerebellum and brainstem, and high signal intensities in the posterior periventricular triangle portion on T2-weighted images. Gene analysis performed at the age of 6 years revealed an expanded CAG repeat (17/74) at the DRPLA locus. The CAG repeat size was larger in this case than in cases of the adult and juvenile types with later onset, suggesting a correlation between repeat length and age at onset. Genetic examination of the family members was not performed because of her mother's fear and emotional confusion.

A 78-year-old woman who had bronchial asthma for 15 years developed dysesthesia, neuralgia, muscle weakness and atrophy in both feet and her left hand. Prednisolone (maximum dose 80 mg) was not effective, and she displayed gait disturbance. Laboratory findings showed leukocytosis (neutrophils dominant), renal dysfunction, elevation of CRP and positive P-ANCA. Biopsy revealed vasculitis, and reduced density of myelinated fibers. Although steroid pulse therapy improved neuralgia and renal dysfunction, severe disability of motor function and sensory disturbance still remained. Vasculitis syndrome following bronchial asthma indicated Churg-Strauss syndrome (CSS), while severe renal dysfunction and lack of eosinophilia were symptoms compatible with microscopic polyangiitis (MPA). The present case showed properties of both MPA and CSS.

Measles pneumonitis, as well as encephalitis, is the most important complication associated with mortality in measles. Many medications including steroids and vitamin A have been applied to pediatric measles pneumonitis. However, the efficacy of such medication has not yet been established. This study is aimed at evaluating the effectiveness of surfactant replacement therapy in pediatric measles pneumonitis. Five patients (aged 1-2 years) with measles pneumonitis were transferred to our emergency center. On the transferred day, Surfactant-TA was administered by intratracheal method. After administration of surfactant, PaO2/FIO2 increased from 63.6 +/- 11.0 (mean +/- SE) to 206.2 +/- 54.1 in an hour and to 163.8 +/- 34.8 in 24. At the same time, the CO2 elimination and the dynamic compliance were improved. Because of these effects, the peak inspiratory pressure employed in mechanical ventilation could be reduced. It is concluded that surfactant replacement therapy can prevent the patients with measles pneumonitis from hypoxemia and ventilation-induced lung injury. However, further study is needed to maintain the improved oxygenation. Recently, it is reported that the effect of exogenous surfactant on oxygenation and activity of pulmonary neutrophils is regulated by the amount and/or concentration of administered surfactant. Therefore, it is an urgent issue to find out the optimum amount and concentration of exogenous surfactant used clinically.

A 56-year-old man experienced dyspnea since August 1995 and the chest X-ray film showed abnormal shadow. The diagnosis of bronchiolitis obliterans organizing pneumonia (BOOP) was established based on the histological findings of transbronchial lung biopsy. The patient was treated with prednisolone and symptoms improved. Myalgia and muscle weakness developed associated with relapse of BOOP after withdrawal of prednisolone. Patient was admitted to our department on December 1995 for further examination. An increased level of serum CPK, histological findings of muscle biopsy consistent with myositis, and positive anti-Jo-1 antibody were identified. Those findings supported a diagnosis of polymyositis (PM), and BOOP was considered as a pulmonary complication of PM. Myositis and pulmonary lesion improved after second course of steroid therapy and patient was discharged on May 1996. Both chronic pulmonary fibrosis and acute progressive interstital pneumonia are well known as pulmonary lesion associated with PM. The former is frequently recognized in cases of PM with anti-Jo-1 antibody and the latter is often observed in cases without autoantibodies. The association of PM and BOOP, however, has rarely been reported. The findings that BOOP frequently preceded PM and anti-Jo-1 antibody was positive in half of the cases were observed in the literature.

A 67-year-old woman presented with a 1-year history of gradual weight loss, reduced mental activity, muscle weakness, and urinary dysfunction. Neurological examination revealed mild lethargy, severe muscular atrophy, and diminished deep tendon reflexes in the extremities. The levels of vitamin B1 and folate in blood were low: 1.9 micrograms/dl (normal range 2.0-7.2) and 0.7 ng/ml (normal range 4.0-12.0). respectively. A lumbar puncture was done. The pressure of the cerebrospinal fluid was within normal limits, the level of protein was very high (467 mg/dl), and only a few lymphocytes were seen. A nerve-conduction study showed low amplitudes of action potentials and slow conduction velocities in both the motor and sensory nerves. Myelin irregularity, "onion bulb formation", and axonal atrophy were seen in a specimen obtained by sural nerve biopsy. A T2-weighted magnetic resonance image of the brain showed ventricular dilatation, high-intensity signals around the lateral ventricles, and a flow-void sign of the cerebral aqueduct. Radioisotope cisternography (111In-DTPA) disclosed ventricular reflux and slow clearance of the tracer from the ventricles. These findings indicated the presence of chronic inflammatory demyelinating polyneuropathy, nutritional polyneuropathy, vitamin B1 deficiency, folate deficiency, and normal pressure hydrocephalus. In this patient, the high level of protein in the cerebrospinal fluid may have caused the hydrocephalus.

A 76-year-old woman was found to have acute aseptic meningoencephalitis with meningial irritation, disturbance of consciousness, elevation of cell counts in cerebrospinal fluid, and swelling of a right temporal-lobe lesion on a CT scan of the head. Muscle weakness in the lower extremities and urinary dysfunction developed and progressed gradually. The protein content of cerebrospinal fluid was high, and the distal latencies of F waves were prolonged, which suggested that the inflammation extended to the nerve roots. Sjögren's syndrome was diagnosed on the basis of atrophy of the labial salivary glands; invasions of lymphocytes and plasma cells to the intercellular space; and elevation of the titers of serum antinuclear antibody, anti-SS-A antibody, and anti-SS-B antibody. The patient had no xerosis. Aseptic meningoencephalitis was the first manifestation of Sjögren's syndrome. In recent years, several cases in which Sjögren's syndrome was associated with aseptic meningitis have been reported. However, we know of no previous report of such a case in a patient of this age. Aseptic meningoencephalitis can be the first manifestation of Sjögren's syndrome.

Lipoprotein(a) (Lp(a)) is an independent risk factor for cardiovascular diseases in non-diabetic people, but few studies have been done in diabetic patients. To investigate whether Lp(a) is a risk factor for cardiovascular disease in elderly people with diabetes, we examined the association of Lp(a) and serum lipid levels (total cholesterol: TC; triglycerides: TG; and high-density lipoprotein cholesterol: HDL-c) with the incidence of coronary artery disease and cerebrovascular disease. We studied 354 outpatients(131 men and 223 women, 60-97 years of age) with non-insulin-dependent diabetes mellitus. The mean concentration of Lp(a) was 21.1 +/- 19.6 mg/dl and the median was 14.0 mg/dl. The Lp(a) concentration did not correlate significantly with age or with sex, but it did correlate significantly with TC (r = 0.152, p < 0.05) and with the level of apoprotein B (r = 0.168, p < 0.05). The incidence of cerebrovascular disease was significantly higher in patients with high concentrations of Lp(a) (> or = 30 mg/ dl) than in those with low concentrations (< 30 mg/ dl). Multivariate logistic regression analysis revealed that male sex, hypertension, a high level of HbA1c, a low level of HDL, and a high level of Lp(a) were independent risk factors for cerebrovascular disease. The incidence of coronary artery disease tended to the higher in those with high concentrations of Lp(a) (> or = 30 mg/dl). However, multivariate logistic regression analysis revealed no significant correlation between Lp(a) concentration and the incidence of coronary artery disease. We conclude that a high concentration of Lp(a) is an independent risk factor for cerebrovascular disease in elderly patients with diabetes.
