Postictal Periorbital Petechial Rash

Akioh Yoshihara, Hiroshi Mishima, Naoshi Saito, Yoshikazu Ugawa
2017 Internal medicine (Tokyo. 1992)  
A 16-year-old boy, with a history of juvenile myoclonic epilepsy, which had been treated with valproic acid since he was 9 years of age, presented with bilateral periorbital rash. His family had found him in a stupor state after groaning early the previous morning. The patient had a history of morning myoclonic seizures and absence seizures, but no history of generalized tonic-clonic seizures. An electroencephalogram showed generalized polyspike-wave abnormalities. The results of neurological

The petechial rash on the bilateral periorbital regions (Picture) disappeared spontane-ously within one week. Epilepsy-induced thoraco-cervicofacial purpura is a rare finding after generalized tonic-clonic seizures. It has previously been suggested that this finding may be caused by increased blood pressure or a high degree of congestion during the tonic-clonic phase, such as occurs in the Valsalva maneuver (1). This purpura may be a valuable indicator of epileptic seizure, even in the absence of other signs of epilepsy (2). Based on these arguments, we diagnosed this rash as a postictal periorbital petechial rash.

Lethal Visceral Calcinosis in Fulminant Hypercalcemic Crisis

Shu Yoshihara, Hiroshi Kobayashi, Yoshiro Otsuki, Sadahiro Tamashima
2018 Internal medicine (Tokyo. 1992)  
A previously healthy 41-year-old woman was admitted to our hospital with a 5-day history of anorexia and progressive lethargy. Laboratory findings showed hypercalcemia and renal failure. Serum calcium, phosphate and creatinine were 17.2 mg/dL (normal range 9.0-11.0 mg/dL), 10.4 mg/dL (normal range 6.0-9.0 mg/dL) and 3.8 mg/dL, respectively. Initial chest radiography and computed tomography showed mild infiltration in her bilateral peripheral lung fields (Picture 1A and B). Treatment with saline solution (total infu-

Comparing Young's Modulus Values of Paperboard Obtained by Four Methods

Hiroshi Yoshihara, Masahiro Yoshinobu, Makoto Maruta
2021 Mokuzai Gakkaishi  
Young's modulus of paperboard was obtained from tensile, static bending, longitudinal vibration, and flexural vibration tests under various specimen configurations, and the obtained values were compared with each other. There were significant differences among the Young's modulus values obtained by the four methods because the lamination construction and inelastic deformation of the paperboard affected the measurement of Young's modulus. Therefore, the method for measuring the Young's modulus

Hiroshi Matsuura, Yasuhiro Kunieda, Nobuhito Yoshihara, Ji Wang Yan, Tsunemoto Kuriyagawa
2007 Key Engineering Materials  
A completely new diamond wheel, named the 3R wheel, has been developed. The 3R wheel has three unprecedented functions, reconfiguration, restoration and recyclability, and is molded from a mixture of special thermoplastic resin filler and diamond powder. The concept of the 3R wheel is to control the quantity and the position of abrasive material by actively using heat. In this study, tungsten carbide (WC) was ground using a thermoplastic resin bonded diamond wheels (radius 1.4 mm) with three

1988 Orthopedics & Traumatology  
169 infants with limited abduction of the hip (bilateral 141, unilateral 28) were radiologically analyzed. Acetabular dysplasia was seen in 34.5% of the bilateral infants and in 57.1% of unilateral ones. 5% of the bilateral and 7.1% of the unilateral cases had a convex type of acetabulum. Retardation of ossification of the femoral capital epiphysis existed in 22.7% of all of the infants with limited abduction of the hip. We believe that it is important to do radiological examination to infants

Phosphate coating techniques for car bodies

Toshio YOSHIHARA, Hiroshi OKITA
1983 Transactions of the Iron and Steel Institute of Japan  
Synopsis In an attempt to prevent rust on car bodies, various improvements have been made through such measures as use of precoated steel sheets, transfer of phosphate treatment toward full dipping, incorporation of cationic ED primer, and adoption of wax injection. Since introduction into Japan in 1978, the full dip process for phosphate treatment of car bodies has been subjected to many studies in the aspect of production techniques as well as in chemicals. Treating practices for the

The phosphate coating plays a particularly important role because of its location between the steel substrate and the painted film. More specifically, it should be capable of coping with new properties of new steel sheet materials and new paint materials not experienced by the industry. Zinc phosphate coating essentially consists of hopeite, Zn3 (P04)2 4H,O and phosphophyllite, Zn2Fe(P04)2.4H,O: a higher phosphophyllite content is more favorable for preventing deterioration of wet adhesion in cationic ED painting. This is due to the superior alkali resistance of phosphophyllite. As compared with the spray process, the full dip process is more advantageous in that more Fe2+ dissolved from the substrate during the initial stage of reaction can be incorporated into the coating. In a galvanized steel sheet, in contrast, the absence of Fe2+ source results in a coating consisting of hopeite alone. Hopeite can however be excellent in alkali resistance in some grain orientations which are controllable by the galvanized layer of substrate and the composition of chemicals. A phosphate coating is more excellent in corrosion resistance, if the grain size is smaller and the porosity is lower. Such a coating is more easily available by the full dip process than by the spray process.

2018 Injury Epidemiology  
The epidemiological patterns of musculoskeletal injuries or disorders in military personnel have not been well documented and a better understanding is required for proper preventative measures and treatment. Here, we investigated musculoskeletal injuries or disorders among members of the Japan Self-Defense Forces. Methods: All orthopedic patients (n = 22,340) who consulted to Japan Self-Defense Forces Hospitals were investigated for their type of injury or disorder, the injured body part, the

Of the traumatic injury patients, the injured body part was the upper extremity in 32%, the trunk in 23%, and the lower extremities in 45% of the cases. The most common injured body location was the knee followed by the hand/finger and ankle. Exercise was the most common cause of injury, followed by traffic accident and military training. Contusions were the most common traumatic injuries, followed by sprains and fractures. Of non-traumatic disorders, the lower extremities were reported as the injured part in 43% of the disorders. Lumbar spine disorders were the most common non-traumatic disorders, followed by tendon and joint disorders. Conclusions: Over one-third of orthopedic cases among members of the Japan Self-Defense Forces are traumatic injuries, with the knee being the body part most commonly injured and exercise being the leading cause of injury.

A Case of Malignant Pheochromocytoma with Holt-Oram Syndrome

Ai YOSHIHARA, Akiyo TANABE, Hiroshi SAITO, Naomi HIZUKA, Akira ISHIZAWA, Reiko HORIKAWA, Kazue TAKANO
2008 Endocrine journal  
A 23-year-old female patient with malignant pheochromocytoma was admitted to the Tokyo Women's Medical University. The patient had been clinically diagnosed with Holt-Oram syndrome at birth. Since she had complex congenital heart disease, chronic heart failure, and severe hypoxia, the risk surrounding surgery to remove the primary tumor was predicted to be very high, and subsequently, chemotherapy was performed. The patient was not able to continue chemotherapy due to adverse effects. However,

To our knowledge, this is the first report of a patient with the combination of malignant pheochromocytoma and Holt-Oram syndrome. A correlation between chronic hypoxia and pheochromocytoma has been reported. This instructive case reminds us to consider the possibility of pheochromocytoma with congenital heart disease when these types of unexpected or unusual symptoms are encountered.
