[Elastofibroma, a rare cause of snapping scapula syndrome].

Scapular pain is a common complaint in daily orthopedic practice. A different type of scapular discomfort, the snapping scapula syndrome that occurs when smooth gliding motion of the scapula upon the chest wall is interfered with is much less common. We studied the syndrome of periscapular pain and discomfort, and present a rare etiology: elastofibroma dorsi, a unique, benign, soft tissue-tumor with unique characteristics.

Excretion of a phosphorus-containing carbohydrate by Streptomyces sp. A50.

A new phosphorus-containing compound (1) was detected by (31)P NMR spectroscopy in Streptomyces sp. A50. Compound 1, 1(alpha)-O-methyl-2-(N-acetyl)glucoseamine-6-O-phosphate-1(alpha)-2-(N-acetyl)glucosamine, exhibited a pK(a) value around zero.

A GCC element and a G-box motif participate in ethylene-induced expression of the PRB-1b gene.

The PRB-1b gene codes for a basic-type pathogenesis-related protein and is activated at the transcriptional level by the plant hormone ethylene. To identify cis-acting DNA elements essential for ethylene induction, deleted and mutant forms of the PRB-1b promoter, fused to the beta-glucuronidase (GUS) coding region, were introduced in transgenic tobacco plants. A 73 bp fragment (X1 region) of the PRB-1b promoter, located between positions -213 and -141, was sufficient to confer ethylene responsiveness to the reporter gene.

Gigantic lipomas.

Two cases of unusually giant lipomas--weighting 5070 and 4000 gm--are described. Tumors were present for 5 years on the back in a 55-year-old man and for 20 years at the anterior compartment of the thigh in an 80-year-old woman. Difficulty in fitting clothes was the first patient's sole complaint, and social pressure was actually the reason that brought him to his doctor.

DNA-protein interactions on a cis-DNA element essential for ethylene regulation.

The PRB-1b gene encodes for a basic-type component of the pathogenesis-related PR-1 protein family. In leaves of tobacco plants, PRB-1b mRNA accumulation is rapidly induced by the application of exogenous ethylene. Promoter deletion analysis was performed in transgenic tobacco plants to delineate cis-acting elements necessary for ethylene responsiveness of the PRB-1b gene.

A basic-type PR-1 promoter directs ethylene responsiveness, vascular and abscission zone-specific expression.

Pathogenesis-related (PR) proteins form a heterogeneous group of host-encoded, low-molecular-mass proteins that are secreted through the exocytic pathway. They are synthesized by the plant in response to various stimuli, including pathogen attack or exposure to certain chemicals. The PRB-1b gene of Nicotiana tabacum codes for a basic-type PR-1 protein whose transcription is regulated by ethylene.

Continuous postoperative regional analgesia by nerve sheath block for amputation surgery--a pilot study.

A pilot study of continuous postoperative regional analgesia by nerve sheath block for lower limb amputation is presented. At the time of exposure of sciatic or posterior tibial nerve trunks during above- or below-knee amputations in 11 patients with ASA physical status III or IV, a catheter was introduced directly into the transected nerve sheath for continuous infusion of 0.25% bupivacaine at a rate of 10 mL/h for 72 h.

Bilateral hip resection for closure of trochanteric pressure sores: case report.

Bilateral resection of the proximal femur, an orthopaedic procedure advocated in selected cases of infected hip joints, can be useful in the treatment of extensive pressure sores in paraplegics. It is especially indicated in those cases where a total thigh flap is considered with the advantage of saving the limb, and by shortening the leg providing more skin and soft tissue for closure of the pressure sores.

Clinical and pathological changes caused by the interaction of lasalocid and chloramphenicol in broiler chickens.

Uncommon and abnormal gait, characterised by toe walking and progressive leg weakness, was observed in a large broiler flock in Israel. Identical clinical signs were reproduced when young chicks received feed supplemented with lasalocid (Abatec-Roche), and chloramphenicol at normal recommended levels, for 12 days or more. The clinical and pathological findings suggest a neuromuscular toxic effect of lasalocid-chloramphenicol interaction in broiler chicks.

Seasonal variation in serum levels of vitamin D metabolites and parathormone in geriatric patients with fractures in Southern Israel.

In 41 geriatric patients with long bone fractures, a seasonal variation was observed in the serum levels of 25-hydroxyvitamin D (25-OH-D), 1,25-dihydroxyvitamin D [1,25(OH)2D], 24,25-dihydroxyvitamin D [24,25(OH)2D] and parathormone (PTH). The serum concentrations of vitamin D metabolites correlate positively, while that of PTH correlates negatively with day length and global solar radiation in southern Israel. Our data suggest that the higher serum levels of vitamin D metabolites during the summer suppress PTH secretion.

Parathormone, calcitonin, and vitamin D metabolites during normal fracture healing in geriatric patients.

In order to study the role of calcium-regulating hormones during callus formation in elderly patients, serum levels of parathormone (PTH), calcitonin (CT), 25-hydroxyvitamin D [25-OH-D], 1,25-dihydroxyvitamin D [1,25(OH)2D], 24,25-dihydroxyvitamin D [24,25(OH)2D], and calcium (Ca) were determined in 41 patients with fractures of long bones, primarily hip fractures. The parameters were measured on admission and after eight weeks. There were almost no changes in hormone serum levels during bone repair, except for a decrease in serum levels of 1,25(OH)2D from 25.

The influence of age and sex on blood levels of calcium-regulating hormones in dogs.

In order to study age- and sex-related changes in calcium-regulating hormones, serum levels of parathormone (PTH), calcitonin (CT), and vitamin D metabolites were determined in 20 young dogs and 11 old dogs. A highly significant increase in serum levels of PTH was observed in old dogs (1.65 +/- 0.

Mineral and endocrine metabolism during fracture healing in dogs.

The blood levels of parathormone (PTH), calcitonin (CT), vitamin D metabolites, calcium, phosphate, magnesium and alkaline phosphatase (AKP) were determined in 13 young dogs with experimental fractures of long bones. The parameters were measured before the fracture and during healing until the appearance of an early callus. Serum Ca levels were significantly reduced immediately after the fracture (10.

Chronic multifocal symmetrical osteomyelitis. Report of two cases in Bedouin infants.

Chronic multifocal symmetrical osteomyelitis is a rare condition characterized clinically and radiologically by multiple symmetrical bone lesions, a benign course, and a good prognosis. To our knowledge, only 25 cases have been reported in the literature; all of them occurred in patients of European ancestry. We describe two bedouin children, aged 20 and 21 months, who suffered from this disease.

Parathyroid hormone, calcitonin, and vitamin D metabolites during normal fracture healing in humans. A preliminary report.

The metabolism of calcium is regulated by hormones: parathyroid hormone, (PTH) calcitonin (CT), and vitamin D metabolites. To study the physiologic role of these hormones during the process of fracture healing in humans, the blood levels of PTH, CT, 25-(OH)-D3, 24,25-(OH)2-D3, and calcium were determined in 13 young patients with fractures of long bones. The parameters were measured first on admission and again after six to eight weeks.

Hormonal control of fracture healing in a dog with chorea.

An experimental fracture in a dog with chorea was found to heal faster, and with a larger callus, than normal. Serum levels of parathormone (PTH), calcitonin (CT) and vitamin D metabolities were determined during callus formation. Serum concentrations of vitamin D metabolites were lower from the beginning while serum CT levels were higher compared to normal dogs.

Primary liposarcoma of bone. Case report and review of the literature.

Although liposarcoma is a common tumor of the soft tissues of the body, it rarely occurs as a primary neoplasm of bone. An extensive review of the literature from 1930-1980 uncovered fewer than 35 cases. The authors discuss the diagnosis and treatment of a case of primary liposarcoma of bone in the right femur of a 34-year-old Bedouin man.

Phalangeal microgeodic syndrome in childhood. A case report.

A rare case of avascular necrosis of bone of unknown etiology affecting several phalanges of one hand in a 12-year-old Israeli girl is presented. This entity has been described in the literature under the title of "Phalangeal microgeodic syndrome in childhood." Forty cases have been reported mostly from Japan.

Subcapital fracture of neck of femur with complete posterior dislocation of the hip.

A rare case of a posterior fracture-dislocation of the hip joint with an ipsilateral subcapital fracture in a young woman is presented. The isolated femoral head was displaced in the subcutaneous area in the buttock. A possible explanatory mechanism of dual injury is that the posterior fracture-dislocation occurred first and then a lateral blow to the buttock caused the subcapital fracture.
