[Clinical impact of partial sternotomy for off-pump coronary artery bypass].

History of cardiopulmonary bypass has been the pursuit for less invasiveness. Currently, about 60% of primary coronary artery bypass grafting is performed as off-pump coronary artery bypass (OPCAB). We tried to determine whether OPCAB by the lower partial sternotomy could be safely performed in the elderly patients with the age equal to or over 80 years. The number of grafts was 2.4 +/- 0.8 in patients with partial sternotomy (PS) and 2.3 +/- 0.9 in patients with full sternotomy (FS). Postoperative duration of mechanical ventilation in patients with PS was significantly shorter than that in patients with FS (p <0.05). Although the differences were not significant, the incidence of wound and respiratory complications were less in patients with PS than in those with FS. Theoretically, tracheostomy and percutaneous cricothyroidotomy can be safely performed in the early postoperative period after PS. Early ambulation can decrease the complications related to prolonged bed rest. Because dislocation of the sternoclavicular joint and/or brachial plexus injury do not occur, upper extremity movement remains unrestricted and shoulder pain does not occur. Our results suggested that OPCAB using PS could become the standard procedure in the elderly patients with multiple risk factors.

Friedrich's disease: a case report.

An eight-year-old girl was presented with painful swelling of the sternoclavicular joint. Radiological and scintigraphic examinations lead to a diagnosis of Friedrich's disease, aseptic necrosis of the sternal end of the clavicle. It is a rare condition which is to be differentiated from osteomyelitis, arthritis, or tumor. Because it is a self-resolving, benign condition, awareness of this disease will save the patient from unnecessary surgery.

[Computerized tomography of the female thorax after mastectomy: the most important topometric data from the viewpoint of radiation].

The author analysed postoperative CT images of 77 patients operated on carcinoma of the breast and performed topometric measurements on the level of sternoclavicular joints parasternal, and in the centre line of the sternum in the height of the second and sixth intercostal space as well as on the thorax wall medioclavicular and on the forepart of the axillar line. The values measured corresponded to the literary data in general except those of the second intercostal space and of the axilla. The author stresses the necessity of CT series when making radiation planning of breast cancer.

A prospective necropsy study of arthritis in acquired immunodeficiency syndrome.

Thirty-two knee and 23 sternoclavicular joints from 35 subjects with acquired immunodeficiency syndrome were examined prospectively at necropsy. There were two instances of opportunistic infectious arthritis: one caused by Staphylococcus aureus, the other by Sporothrix schenckii. In five other subjects, para-articular bone was infiltrated by granulomatous or neoplastic sequelae of the human immunodeficiency virus infection. There was no immunohistochemical (p24 antigen) or other evidence for existence of a specific acquired immunodeficiency syndrome arthritis.

Computed tomography of musculoskeletal trauma.

Radiology plays a crucial role in the evaluation of the acutely traumatized patient by providing information that allows timely and appropriate management to be instituted. With few exceptions, notably the skull, plain films remain the primary imaging technique for the diagnosis of skeletal trauma. Computed tomography (CT) has become an important adjunctive procedure in the evaluation and diagnosis of trauma, particularly in complex anatomic areas, including the sternoclavicular joint, the pelvis, and the spine, and in many hospitals has virtually replaced conventional tomography. It may be combined with arthrography or enhanced by intravenous or intrathecal contrast material. This article reviews the uses of CT in the diagnosis and evaluation of musculoskeletal trauma and its complications.

[Roentgenological analysis of sternocostoclavicular hyperostosis by computed tomography].

Roentgenological analysis of the anterior chest wall was performed in twenty six patients with sternocostoclavicular hyperostosis. Initial hyperostotic change was seen at the first costosternal junction with ventral protrusion. Hyperostosis gradually developed around the first ribs, and irregular hyperostotic changes were also seen along the costoclavicular ligaments. Even in the final stage, however, sternoclavicular joint spaces were well preserved. These findings suggest that sternocostoclavicular hyperostosis is a disorder initiated around the costal cartilage including the periosteum and perichondrium, and that arthritis is not a condition stemming from that disorder.

[Establishment and characteristics of a human synovial sarcoma cell line].

A human synovial sarcoma cell line (HSS-84), from a painful mass excised locally near the left sternoclavicular joint, was established and has been continuously propagated in vitro for more than one year through 54 passages till the end of 1985. Doubling time was 65 hr. The index of mitosis was 28.8%. The chromosome number for most of the cells was hypertriploid. The cells, stored in liquid nitrogen, had a good revival. Cytologically, some cells, showing elongated, spindle, stellate or spidery shape with prominent processes, were arranged in loose or bundled pattern, similar to sarcoma cells; some cells showed ovoid and polygonal in mosaic arrangement, similar to epithelioid cells. Both features indicated biphasic differentiation of the cells. By electron microscopy, the cells consisted of light and dark cells with microvilli and obvious abnormality. Histopathologically, the tumor, from which HSS-84 originated, was a biphasic differentiation synovial sarcoma. It was composed of malignant spindle interstitial cells and malignant epithelioid cells lining the clefts or spaces. The latter was similar to cultured cells by electron microscopy. HSS-84 was identical with the donor. HSS-84 establishment will be useful for research on diagnosis, therapy, origin and biphasic differentiation of the synovial sarcoma.

Computed tomography of rheumatologic disorders. Part II.

The advent of computed tomographic (CT) scanning has initiated a revolutionary approach to the evaluation of articular disease. CT affords the opportunity to noninvasively evaluate both osseous and soft tissue structures during a single diagnostic examination. An optimal CT study demands proper technique, including a localization image, appropriate slice thickness and spacing, and window/level manipulation. The examination must be tailored to the specific indication for the study, which may include degenerative processes, inflammatory disease, or unexplained clinical symptomatology.

Condensing osteitis of the clavicle: case report and review of the literature.

Osteitis condensans of the clavicle is a benign, often painful disorder of unknown etiology manifested by bony sclerosis of the clavicular head with an uninvolved sternoclavicular joint. The case presented demonstrates the characteristic scintigraphic findings of osteitis condensans of the clavicle. A review of the published pathologically proven cases reveals this disorder to have distinctive clinical and radiological features that allow differentiation from infection, neoplasia, and arthritides in most instances. The frequent observation, as in this case, of devitalized bone and marrow fibrosis with remodeling of cancellous bone suggests that osteonecrosis may play an important role in the pathogenesis of this disorder.

[A safe method for infraclavicular puncture of the subclavian vein].

Investigations of 25 human cadavers, using various anatomical techniques, led to the development of a safe and simple method of subclavian venipuncture. This method was tested with special regard to possible complications. The authors describe the guidelines for the choice of the point where the skin has to be penetrated as well as of the point towards which the needle has to be directed. While the latter is situated a little beyond the spinous process of the seventh cervical vertebra, the other is determined as follows: the distance between the acromion and the sternoclavicular joint is divided into three parts, and the junction between the medial and central third of this distance is marked on the skin. Starting from this point a vertical is dropped towards the line between the acromion and the sternal angle. The point of intersection between this line and the vertical is where the cannula penetrates the skin. After a distance of between 2.5 and 4.5 cm the top of the needle reaches the subclavian vein. Even if the vessel is pierced through and through, no complication such as pneumothorax, laceration of arteries, lesions of the adjacent nerves, etc., can occur. Using this method the authors performed catheterization of the subclavian vein in 200 patients, and there were no complications at all.

[Catheterization of the jugular vein (vena jugularis interna). The advantage of Boulanger's technic].

The present study was designed to emphasize the technical accuracy of the percutaneous internal jugular vein approach in operative reanimation (Boulanger Technik). In 18 specimens with hyperextended neck, the cannulation of the internal vein was achieved from a puncture point situated 7.3 cm lateral to the sternoclavicular joint, at level of the top of the thyroid cartilage; then the catheter was pushed slanting downwards an laterally by 50 degrees with respect to the inner border of the sternomastoid muscle toward the union medial third-middle third of the clavicle. The acknowledge of the distance between the puncture point and the right auricle allows to ascertain the proper location of the catheter. The use of the internal jugular vein can be recommended in operative reanimation because its cannulation is harmless and easy to carry out and both its large size and deep situation lower the usual risks of more distal venous catheterizations.

Sternocostoclavicular hyperostosis. A case report and review of the literature.

Sternocostoclavicular hyperostosis (SCCH) or intersternocostoclavicular ossification is a recently recognized disorder of unknown origin. SCCH is characterized by painful, condensing hypertrophy of the sternum, both clavicles, and the upper ribs. Since its original description by Sonozaki in 1974, approximately 40 cases have been reported, mainly in the Japanese literature. This peculiar hyperostotic syndrome is often misdiagnosed. The differentiation from osteitis deformans can be difficult. Clinically, the disease produces a swelling in the upper chest area with persistent, pulling pain exacerbated by cold and dampness. The condition is a nonspecific inflammatory syndrome. Radiographs usually show symmetric hyperostosis of the sternal portions of the clavicles, synostosis of the sternoclavicular joints, a thickened sternum, and varying degrees of involvement of the upper ribs and intercostoclavicular space. Biopsy specimens reveal hyperostotic sclerosis of the cancellous bone. Although the cause of the syndrome is unknown, clinical, radiologic, and histologic findings indicate that it represents a distinct entity. The treatment of SCCH remains symptomatic.

Effects of human calcitonin on pain in the treatment of Tietze's syndrome.

Tietze's syndrome consists of pain, tenderness, and swelling of the costosternal or sternoclavicular joints. The etiology is unknown, although microtrauma or rare infections have been though to be responsible for the lesion. Conventional therapy consists of anti-inflammatory drugs, sometimes combined with chemotherapeutic agents and antibiotics. Surgery is usually deemed necessary for cases that do not respond to conventional therapy. Experience with the use of human calcitonin in five patients suffering from severe Tietze's syndrome who did not respond to conventional therapy is reported. Symptoms improved within seven days, and all symptoms and signs had disappeared after one month of treatment. The beneficial effects of calcitonin are believed to result from the hormone's well-known analgesic and immunomodulating effects.
