We herein describe three patients with thoracic disk herniation (TDH) that presented with acute myelopathy at the Tokyo Metropolitan Neurological Hospital between 2014 and 2021 (age range, 45-76 years; male/female ratio = 1:2), with a focus on the mechanisms underlying their development. All patients had sudden-onset gait disturbance due to acute nontraumatic paraparesis. The specialties of the doctors at the first hospital were neurology and orthopedic surgery. TDH was overlooked at the first hospital, and the patients were referred to our hospital. The TDH in all cases was of the central type; however, since they were small, no spinal stenosis was observed. The key feature of all three cases is the small anterior deformation of the spinal cord, making a vascular etiology for the symptoms more plausible than a compressive etiology. After a follow-up of several months or years, two out of three patients underwent surgery with the use of the transfacet pedicle-sparing approach due to residual symptoms. Intraoperative ultrasonography showed that the spinal cord was anchored to TDH by the dural attachment of dentate ligaments. The physical relationship between the dentate ligaments and TDH may be associated with the vascular cause of the symptoms of small TDH.

In the last 10 years,18 cases of schwannoma and 1 case of neurofibroma of the head and neck were seen in the Shinshu University Hospital. Patient age ranged from 17 to 78 years and the average was 48.5 years. The tumor was seen most often in the parapharyngeal space (33%). The nerve origin of the tumors was identified in 10 cases: 1 in the tenth cranial nerve,2 in the seventh,1in the fifth,1 in the ninth and 2 in the sympathetic . additional cases were probably of anterior ethmoidal origin and great auricular nerve origin, respectively. One case showed recurrence 6 years later after the operation.

We report an acute myocardial infarction in a patient with a single coronary artery. The right coronary artery arose from the middle portion in the left anterior descending artery through the transverse branch. This type of single coronary artery has not been previously reported. Moreover, this is the first report in which the culprit lesion in a patient with a single coronary artery was observed by intravascular ultrasound and coronary angioscopy. The patient underwent successful coronary stent deployment.

The coeliac trunk is a wide branch of the abdominal aorta which arises from just below the aortic hiatus. It is about 1.25 cm. long (5). In our cadaver the length of the coeliac trunk was observed to be 4.5 cm. Additionally the inferior phrenic arteries which normally arise from the abdominal aorta were derived from the coeliac artery.

The first object of this study was to investigate the constituent factor of physical flexibility. The second purpose was to reconsider if the measures of physical flexibility which have been customarily used are valid, and choose those measures which have high validity. To investigate this the method of factor analysis was used.
The following results were obtained:
1) It has been recognized that there are eight constituent factors (F1-F8) of physical flexibility. Of those factors, the first concerns the flexibility of the .
) To choose the measurement items, it is valid to choose those items which showed a high factor loading to each factor. In this study, seven items (trunk flexion, upperarm raising, sideward neck bending, instep flexion and extension, wrist pronation and supination) were chosen.
3) From the results written above, it can be seen that it is inappropriate and insufficient to measure only the flexibility of the trunk. But to simplify the measurement method, physical flexibility can be estimated by measuring trunk flexion and sidewards bending.

Twelve cases of aneurysmal fibrous histiocytoma of the skin, from 7 male and 5 female patients with an age range of 24-65 years (mean: 38.5 years), are described. Anatomical distribution ; lower limb/limb girdle (6 cases), upper limb/limb girdle (4 cases) and ( cases) . Lesional size ranged from 0.2cm to 6cm (mean: 1.5cm) . Two patients noticed rapid growth in tumor size as well as tenderness.
Histologically, prominent blood-filled spaces were obserbed in the cellular area of the lesion. The spaces lacked an endothelial lining and were surrounded by the area with prominent deposition of hemosiderin pigments, numerous siderophages, and multinucleated giant cells with hyperchromatic nuclei. In seven cases (58%), in addition to the cellular area, fibrous area was observed in the periphery of the lesion. We presumed that, in adittion to repeated minor trauma, a mechanical stress to the cellular area from adjacent fibrous area might be another factor in the formation of blood-filled spaces in aneurysmal fibrous histiocytoma.

Objectives: The aim of this study was to assess the effects of individual and work-related factors on the incidence of shoulder pain in a large French working population. Methods: A total of 3,710 workers of a French region were randomly included in a cross-sectional study between 2002 and 2005. They completed a self-administered questionnaire about musculoskeletal symptoms, individual factors and exposure to work constraints. In 2007, 2,332 responded to a follow-up questionnaire. The Nordic questionnaire was used both times to assess shoulder pain during the preceding 7 days. Associations between incident shoulder pain and individual and work-related factors at baseline were studied by multivariate logistic regression for both genders. Results: A total of 946 men and 709 women without shoulder pain at baseline were eligible for the analyses. At follow-up, 105 men (11.1%) and 145 women (20.5%) reported shoulder pain. For men, age (OR 3.3, 95% CI, 1.7–6.5 for ≥50 yr), working with arms above the shoulder (1.5; 1.0–2.3) and high perceived physical exertion (1.6; 1.0–2.5) increased the risk of incident shoulder pain. For women, the factors associated with incident shoulder pain were age (2.9; 1.5–5.8 for ≥50 yr), obesity (2.5; 1.4–4.5), temporary employment (2.1; 1.1–3.7), high perceived physical exertion (2.2; 1.4–3.5) and low decision latitude (1.6; 1.0–2.3). Conclusion: Age was the strongest predictor of incident shoulder pain in both genders. BMI and biomechanical and psychosocial factors were also identified as risk factors, whereas no factor related to work organization remained in the final models.

Myopericytoma is a benign tumor composed of cells that show apparent differentiation towards putative perivascular myoid cells called myopericytes. To date, only a small number of series describing myopericytomas have been reported. Here, we report a case of pulmonary myopericytoma presenting as multiple nodules in a 26-year-old man. Clinical presentation, radiological features and histopathologic findings of the patient are also discussed. The result of the histology combined with the immunohistochemical analysis led to a diagnosis of myopericytomas. To our knowledge, this is the first report of myopericytoma showing pulmonary involvement.

The investigation on the epiphytic bryophyte community on Cornus controversa HEMSL in Shiia cuspidata forest, Mt. Kamimata Kochi Prefecture, Shikoku, is reported. The epiphytic bryophyte community on Shiia cuspidata MAKINO in the present forest has already been reported(1957,159-162). The flora, vertical distribution and growth form of the epiphytic species on Cornus controversa HEMSL are showed Table 1. There were found 11 species of Musci and 30 of Hepaticae on the trunks of the sample trees. Dominat species on the trunks of the sample trees. Dominat species on the part of trunk base (0-1 m. in height) are Plagiochila japonica and Neckera yezoana, on the (-7 m. in height)aare Forrostroemia trichomitra and Brachiolejeunea sandvicensis, on both parts of the crown base and crown (8m in height) are Frullania truncatifolia. As above mentioned the species on the bark of Cornus controversa and the dominant species on Shiia cusupidata are shown Table 2. Common species on both tree-trunks are Brachiolejeunea sandvicensis and Frullania truncatifolia. In the preceding study, the writer reported six distributional types by the vertical range and the value of frequency on the treetrunks. These vertical distribution-types and the typical species of each types on Shiia cuspidata MAKINO and Cornus controversa HEMSL are shown in Table 3. The common species of vertical distributiontypes on both tree-trunks are Plagiochila japonica(Type A), Pycnolejeunea obutusilobula(Type C) and Brachiolejeunea sandvicensis (Type E). The ratio of species number of growth form on different levels of sample trees are shown Table 4. The chief growth form is the Hardly pressed mat type(Hp)in the present epiphytic community.

An incidence of a left superior vena cava with a left azygos vein was found in a cadaver during an Osaka Dental University student’s dissection practice session in 2002. The left superior vena cava began from the confluence between the right and left brachiocephalic veins, and extended directly into the left superior edge of the coronary sinus. No right superior vena cava was observed. The left azygos vein, receiving the bilateral intercostal veins, extended into the left superior vena cava. The developmental mechanism of the left superior vena cava was considered as follows; because the proximal part of the left anterior cardinal vein and the left common cardinal vein remained, and the proximal part of the right anterior cardinal vein and the right common cardinal vein degenerated and disappeared. The developmental mechanism of the left azygos vein was considered as follows; because the proximal part of the left posterior cardinal vein remained, and the root of the azygos vein was formed.

For the purpose of clarifying the diurnal change of the human height measurements, the stature, cervicale height and right spina iliaca anterior superior height of 10 female students (19-26 years of age) were taken twice in one and another day. The measurement was practiced at 22 o'clock and every 2 hr from 6 (just after the hour of rising) to 16 o'clock on the following day, i.e., 14 times for each subject.
The Variance Analysis Method was made using 3 factors; measurement hours (6 levels), subjects (10 levels), and measurement dates (2 levels). Reduction occured on the stature, head and cervical height, and lower limb height were discussed respectively.
The following conclusions were obtained :
1) The diurnal change takes place mainly on the .
) Total reduction of the stature from 6 to 16 o'clock is 1.5 cm on an average. Sixty % of that occurs about 8 o'clock and 80% of that does about 10 o'clock.
3) It is desirable to avoid the stature measurement within 3 hr after rising, because the physiological statural reduction during this period exceeds the measurement errors.

Heat flux from the human skin to the environment was measured with heat flux transducers over the entire skin surface of a male subject. The total heat flux for bare skin was 113 W and when the subject wore a loose sports shirt and trousers was 84.9 W, in a room at 20°C. Heat flux distribution was found to be approximately symmetrical from the centerline of a torso without clothes. An approximate correspondence with skin surface temperature was obtained. For comparison, a constant temperature bath made of stainless steel plates was constructed in the shape of a human body. The total heat flux from this human model, measured by the previous transducers, agreed fairly well with the total electric energy supplied to the constant temperature bath.

Ikeda taenioides (Ikeda, 1904) (Annelida: Thalassematidae: Bonelliinae) is the world’s longest spoon worm species, which possesses an extremely long tape-like proboscis with a striped color pattern and a large brownish red trunk. This species is endemic to the Japanese Islands and inhabits a deep vertical burrow in intertidal and subtidal sand flats. Their proboscis, which extends from its small burrow opening, has been frequently observed around Japanese coasts. However, sampling of the main body (i.e., trunk) has been extremely rare because it always stays within a deep part of the burrow. Here, we report the success of the sampling of two specimens of I. taenioides with trunks in two different localities of the Seto Inland Sea (i.e., Ohmishima and Hachi), Japan, in 2019 and 2020 using a yabby pump. This is the first sampling of the trunk of I. taenioides in 88 years after its last collection in Onomichi Bay in 1931. We described the trunk color and morphological characteristics of the two specimens, including the internal anatomy. The trunks of the two specimens showed different colors, that is, pale brown (Ohmishima) and deep brownish red (Hachi). However, they were not distinguished to the species level by the comparison of partial COI sequences, suggesting that I. taenioides has an intraspecific variation in trunk color. Despite the difference in the sampling seasons (Ohmishima: June, Hachi: February), both specimens included numerous ripe eggs. According to previous studies, those collected in November and December also included numerous ripe eggs. Taken together, I. taenioides may be reproductive throughout the year or have multiple reproductive seasons per year.
