    Notes: Diamond turning was carried out along the [110] direction on the (001) plane of single-crystal silicons at extremely small depths of cut of 100 and 500 nm. Cross-section transmission electron microscope observations revealed that turning had converted the layers of the surface into an amorphous structure directly, as well as in continuous chips. The thickness of the layers was about 150 nm in spite of the depth of cut. Under the amorphous layer, another damaged layer with many dislocations was formed, the thickness of which was about 2 and 3 μm at 100- and 500-nm cutting depth, respectively. At 500-nm cutting depth, microcracks were formed through the accumulation of excessive dislocations. At both depths of cut, however, the dislocations were mostly oriented along the 〈110〉 directions within the {111} planes. It was found that ductile-regime turning could be achieved by amorphization and deformation based on the {111}〈110〉 slip systems. © 1994 American Institute of Physics.

    Notes: Abstract A 70-year-old woman presented with a huge tumor in her left breast, which had rapidly increased in size causing cutaneous erosion. She underwent a simple mastectomy, at which time the tumor was found to be an encapsulated multilocular cystic lesion containing dark fluid. Histological examination disclosed the characteristic features of malignant hemangiopericytoma, including the perivascular lamellar growth of atypical mesenchymal cells with vimentin-positive cytoplasm. Multiple irregular vascular luminal formation was also conspicuous. The characteristics of this lesion are discussed together with a review of the previous literature on this unusual neoplasm.

    Description / Table of Contents: Résumé De mars 1977, à octobre 1983, les auteurs ont opéré 6 sténoses bénignes des voies biliaires chez 4 femmes et 2 hommes, leur âge étant compris entre 55 et 69 ans. Les techniques opératoires suivies eurent pour but de préserver l'intégrité de la papille de Vater. Elles ont consisté en anastomose terminolatérale biliaire, reconstruction du canal biliaire en employant un segment de la vésicule ou le moignon cystique ou encore en utilisant un “patch” jéjunal. Le suivi de ces interventions s'étend de 8 mois à 7 ans et 4 mois. La tactique a été de préserver les fonctions de la papille de Vater dans la mesure du possible pour respecter la physiologie biliaire. Les auteurs conseillent d'avoir recours au patch jéjunal quand un moignon cystique n'est pas disponible; cette méthode en fait ne peut être appliquée qu'en présence d'une sténose biliaire dont la longueur est inférieure à 3 cm. Dans 2 cas, où elle été employée elle a donné d'excellents résultats.
    Abstract: Resumen En presencia de estrecheces benignas de los canales biliares los cirujanos generalmente realizan coledoco-yeyunostomía o coledocoduodenostomía como forma de manejo operatorio. Sinembargo, en ocasiones se producen complicaciones indeseables como resultado de estas operaciones, tales como colangitis recurrente, estrecheces de la anastomosis o formación de cálculos intrahepáticos. Con el objeto de evitar este tipo de problemas, una operación que logre la conservación de la papila Vater y de su función viene a significar algo ventajoso. Entre marzo de 1977 y octubre de 1983 tuvimos 6 pacientes con estrecheces biliares benignas. Cuatro eran mujeres y dos hombres, con edades entre 55 y 69 años. Estos pacientes fueron tratados mediante operaciones conservadoras de la papila. Tales operaciones fueron la anastomosis término-lateral de los canales biliares, la reparación biliar utilizando una parte de la vesícula biliar o un remanente del canal cístico y la repación biliar utilizando un parche de pared yeyunal. El periodo de observación postoperatoria osciló entre 8 meses y 7 años cuatro meses. Nuestra política es la de conservar la función de la papila de Vater cuando ésto sea posible, puesto que ello significa un flujo de bilis fissiológico. Nosotros recomendamos especialmente el uso de un parche yeyunal para la repación biliar, en casos en los cuales no exista un remanente utilizable de canal cístico. Este método es aplicable cuando la estrechéz biliar es de menos de 3 cm. Hemos operado dos pacientes con este método y los resultados han sido enteramente satisfactorios.
    Notes: Abstract From March 1977 to October 1983, we examined 6 patients with benign bile duct stricture. Four were female and 2 were male, ranging in age from 55 to 69 years. These patients were treated by operative methods in which the papilla of Vater was preserved. These operative methods were end-to-side anastomosis of the bile ducts, repair of the bile duct utilizing a part of the gallbladder or a remnant of the cystic duct, and repair of the bile duct using a patch of jejunal wall. The postoperative observation period is 8 months to 7 years and 4 months. It is our policy to preserve the function of the papilla of Vater when possible because with this method the flow of bile is uninterrupted. We especially recommend a jejunal patch for repair of the bile duct, when no remnant of the cystic duct is available. This method is applied when the bile duct stricture is less than 3 cm long. We have operated on 2 patients with this method and the results have been completely satisfactory.

    Notes: Abstract A case of 22-year-old man suffering from ulcerative colitis, in whom Weber-Christian panni culitis and musculitis occurred simultaneously, is reported. He had suffered from ulcerative colitis for 7 years and he again had bloody stools 1 month before being admitted. Two weeks before admission, large (2–4cm) subcutaneous tumors appeared. Weber-Christian panniculitis, musculitis, and active stage ulcerative colitis were diagnosed. All the symptoms went into remission after steroid therapy. The possibility of the existence of a common antigen in enterobacterial wall, colonic epithelium, and adipose tissue was suggested.
