[A case of open carpo-metacarpal dislocation complicated by dislocation of the trapezoid bone].

A case of open carpo-metacarpal dislocation complicated by dislocation of the os trapesium is reported in this paper. The patient's wrist healed with good functional results, despite a partial mistake in diagnosis. The authors draw attention to the fact, that X-ray films taken at admission must be analysed carefully and intraoperative X-rays films must be taken. By demonstration their own mistake in diagnosis and treatment, the authors hope that a similar mistake will be avoided. Following early open or closed reduction, a temporary wire fixation of the metacarpal bones to the carpal bones is recommended in order to prevent redislocation.

Lipid bilayer ultrastructure. Electron density profiles and chain tilt angles as determined by X-ray diffraction.

High resolution (6A) electron density profiles have been computed on an absolute electron density scale for bilayers composed of both saturated fatty acids and fatty acids associated with the alkaline earth series of divalent cations. Lowangle X-ray diffraction data have been interpreted by an isomorphous replacement technique. The position on the X-ray film of discrete wide-angle reflections has provided direct information on the hydrocarbon chain packing and chain tilt in these bilayers. These results have been correlated to an electron microscopy study of the same bilayers (Waldbilling, R. C., Robertson, J.D. and McIntosh, T. J. (1976) Biochim. Biophys. Acta 448, 1-14) and also to X-ray diffraction studies of fatty acid crystals. A method for forming and structurally analyzing bilayers of well defined chemical asymmetry is also described.

[A case of cerebral tuberculoma (author's transl)].

A 27-year-old woman was admitted to other hospital for acute pleuritis in May 1977. She suddenly had a focal epileptic seizure in the face with loss of consciousness on July 10, 1977. The same episodes of seizure occurred on Aug. 8, on Oct. 26, on Nov. 22, 1977. She was admitted to our hospital on Dec. 12, 1977. Neurological examinations showed no abnormality. Chest X-ray film showed bilateral severe thickening of the pleura. Plain skull films showed normal findings. Enhanced CT scanning showed a homogenous irregular contour of high density area surrounded by low density area in the right frontal region. The lateral ventricle was slightly shifted to the left side. 99mTc brain scan also detected a spherical abnormal uptake in this area. Right carotid angiography showed no abnormal vessels and increased vascularities. On Nov. 22, 1977, a craniotomy was made over the right fronto-temporal bone, and a walnut sized tumor in the frontal subcortex was totally removed successfully. Histologically, the tumor was diagnosed as brain tuberculoma. The antituberculous therapy (AB-PC, INAH, Rifampicin), high doses of gammabenin, and steroid were given. About four months later, she was in good health without neurologic deficits and returned to her work. The literature was reviewed, and the value of CT scan and RI scan in the diagnosis of cerebral tuberculoma was emphasized.

An unusual complication of subclavian vein catheterization for total parenteral nutrition.

A 25-year-old woman with diabetic ketoacidosis and esophagitis was given total parenteral nutrition to improve her nutritional status. A central venous catheter inserted in the right subclavian vein was well tolerated for three weeks, when infection developed. The line was replaced by a left subclavian line. Within an hour the patient complained of back pain. A chest x-ray film showed that the tip of the catheter was to the left of the mediastinum and that left pleural effusion was present. The line was removed and 1,500 cc of fluid was removed from the left pleural space. The pleural fluid cleared gradually over several days and the patient became asymptomatic.

[Diagnosis and treatment of postoperative infections following hip injuries].

The authors studied the diagnosis and treatment of posttraumatic infections of the hip joint, based on their own material. In case of latent infection the increased sedimentation rate and taking of comparative X-ray films are held important, that shows a narrowing and disappearance of the sclerosed edge of the acetabulum. Following dislocation of the hip joint ankylosis may be attained, but after fractures of the proximal and of the femur the infection cannot be cured, unless the nail and the head of the femur are removed.

[Syringomyelia with severe osteo-articular changes].

Attention was drawn to a patient after admission to the Central Institute of Oncology, and syringomyelia was diagnosed on the basis of X-ray films taken by the author. The deformations were symmetrical and they were localized in the area of innervation of the C VI, VII, D I segment. The radiological diagnosis was proved by the neurological examinations.

[The pneumocephalus in cranio-cerebral trauma (author's transl)].

The accident surgeon is often surprised to see unusual intracranial translucencies on X-ray films of persons with skull injuries. Inexperienced physicians are often unable to immediately identify these translucencies as air enclosures in the intracranial cavity. Physicians not acquainted with pneumoencephalography commonly employed so far in neurological examinations will find it difficult to recognize in the accumulated air the contours of the ventricular, cerebral convolution and cisternal systems. Hence, the relatively rare event of air penetrating into the intracranial space as a result of an injury, is described here on the basis of two of our patients.

Juvenile hyalin fibromatosis.

A boy had multiple large tumors on the scalp, whitish nodules on the nape and both sides of the neck, hypertrophic gingiva, and severe flexural contractures of hip and knee joints. The histopathologic structure of the tumor was characteristic of juvenile hyalin fibromatosis. The tumor cells were embedded in an amorphous eosinophillic ground substance. X-ray films revealed numerous osteolytic and osteociastic lesions that are important findings in the study of this disease.

[A neglected technique for reproducing slides (author's transl)].

Duplicating x-ray films is a matter of interest to all physicians, even if they are not radiologists. The impossibility of a direct reading is a major drawback of reproduction in the form of slides. By contrast, a transparency is an irreplaceable teaching tool. Contact printing of slides on counterpart film is a process within the reach of all departments of radiology. In one single step, this process gives a plate of 100 transparencies on counterpart film costing about 2.20 dollars.

[Ossification of the coracoclavicular ligaments (author's transl)].

Joint-like connections between clavicula and coracoid process are rarely diagnosed. In routine radiological examinations of the thorax, the authors found a posttraumatic ossification of the coracoclavicular ligament in four patients. This phenomenon can occasionally be the cause of shoulder pain. The anatomy and pathogenesis are described, with x-ray film examples, on the basis of four cases.

Electrostatic interactions at charged lipid membranes. Electrostatically induced tilt.

The changes in bilayer structure induced by surface charges in the case of an ionizable lipid were studied by X-ray diffraction, Raman spectroscopy, and film-balance measurements. With increasing surface charge in the ordered phase, the X-ray results show a decrease in bilayer thickness, whereas the hydrocarbon chain packing stays essentially constant, the Raman data signify that the internal chain ordering does not change, and the monolayer studies show a lateral expansion of the bilayer. These results are interpreted in terms of a tilt of the chains caused by the surface charges on the polar heads. The tilt angle between the direction of the chains and the bilayer normal is obtained by a detailed theoretical evaluation. The tilt allows for a better understanding of the electrostatically induced shift of the phase transition temperature and of the shift induced by the binding of water in the case of lecithin in contrast ethanolamine.

Injuries to the ankle and foot in athletics.

Accurate diagnosis in ligament and ligament-bone injuries of the foot and ankle demands a knowledge of the anatomy and mechanics of the foot and ankle, a good history of the mechanism of injury, clinical examination including fingertip palpation and assessment of stability, and adequate x-ray studies, perferably in the deformed position, with stress films and arthrograms in selected cases. By making an accurate diagnosis, early proper treatment is instituted, the athlete is restored to health sooner, and, almost as important, the athlete and the coach get a more realistic prognosis regarding the end result and duration of disability.

Diagnostic decision-process in suspected pulmonary embolism. Report of the Herlev hospital study group.

An analysis was made of how a diagnosis was arrived at in 60 consecutive patients with suspected pulmonary embolism. Patients underwent an initial clinical assessment, a chest X-ray examination, pulmonary scintiphotography, and final clinical assessment. Later, chest films and scintiphotos from these patients and from 120 controls were mixed and reread "blind". The results suggest that clinical physiologists were biased by the clinical information when interpreting the scintiphotos and that clinicians in turn believed implicitly in the scintigraphic report when they made the final diagnosis. The degree of agreement between the first and the second readings of the scintiphotos was unsatisfactory. The radiological findings did not correlate with the clinical and scintigraphic assessments. The study reveals some of the problems which arise in routine clinical practice, when the true diagnosis cannot be established by independent means.

Severe Phenotype in an Indian Family With Progressive Pseudorheumatoid Arthropathy of Childhood.

Progressive pseudorheumatoid arthropathy of childhood (PPAC) is a rare autosomal recessive progressive condition that affects the cartilage of joints and bones. The symptoms of PPAC include stiffness of the joints, bony swelling of the toes and fingers, short stature, kyphosis, and muscle weakness. The radiologic manifestations are often mistaken for juvenile rheumatoid arthritis and include platyspondyly, widened metaphyses, flattened epiphyses, and large femoral heads. The disease is caused by variants in the WISP3 (also known as CCN6) gene, which encodes a member of the WNT1 inducible signaling pathway (WISP) protein subfamily, which belongs to the connective tissue growth factor (CTGF) family. We describe three affected female siblings in an Indian family with PPAC, all of whom manifest a severe phenotype of the disease. The girls all walked with a crouching gait from severe joint contractures. Radiographic findings included generalized periarticular osteopenia and widened metaphyses. The radiographs of the hands and feet showed similar changes with narrow joint spaces, widened metaphyses, and flattened epiphyses. Elbows and knees revealed gracile bones, and contractures with severe muscle atrophy. Spine films were significant for marked beaking, lumbar vertebrae anterior narrowing, irregular end plates and rotational scoliosis. X-rays of the hips revealed deformed femurs, coxa vara, and large flat epiphyses. All affected individuals were compound heterozygotes for two pathogenic variants in the WISP3/CCN6 gene, a novel nonsense variant (c.172A>T [p.Lys58*]) and a 2-base pair deletion (c.740_741delGT [p.Cys247Leufs*31]). This combination of a nonsense and frameshift variant has not previously been reported and may be the explanation for the severe clinical manifestation of PPAC in this family. Further investigation into the mechanism of the disease may provide promising therapies to modify disease progression.

Radiologic manifestations of epidemic haemorrhagic fever with renal syndrome.

Epidemic haemorrhagic fever is a viral disease characterized by acute febrile onset followed by profound renal dysfunction. The endemic areas are widespread throughout the Eurasian continent and the Japanese islands. The patient with EHF usually seeks medical care as an emergency for an "acute abdomen". Consequently the X-ray examination becomes an essential part of the clinical study. We analysed the plain abdomen and chest films of 62 patients with this disease. The radiologic manifestations represented diffuse capillary damage with resultant oedema and haemorrhage, particularly in the retro-peritoneal space. Abnormal findings were seen in 94% of the patients on the plain abdomen, and in 63% on the chest film. The most significant finding was obliteration and blurring of anatomical detail in both intra- and retro-peritoneal cavities and renal enlargement. We believe that simultaneous presence of oedema and effusion in both intra- and retro-peritoneal cavities along with renal enlargement is in practice pathognomic of EHF. Obliteration of the renal outline and cardiomegaly with overt lung oedema was associated with the most severe renal dysfunction.

A reinterpretation of the infrared linear dichroism of oriented nucleic acid films and a calculation of some effective partial changes on the ribose phosphate backbone.

In this paper we show, based on symmetry considerations, that structural information cannot be obtained from the linear infrared dichroism of the dioxy vibrations of the phosphate group of nucleic acids. Consequently, the discrepancies between the results of x-ray structure measurements and linear dichroism measurements are not meaningful. The linear dichroism measurements are instead important for a calculation of transition dipole moments that involve both the vibrations of all the atoms of the nucleotide and their charges. Independent information on either the atomic displacements contributing to a given vibration or the atomic charges permits a refinement of the unknown quantities. Based on the molecular dynamics calculations of Prohofsky et al., atomic charges of DNA are calculated to reproduce the observed linear dichroism results. Some of the resulting charges are unexpected and may reflect the inadequacy of the molecular dynamic calculation.
