To report the fracture of proximal humerus in the lateral anchor site after suture bridge repair. A 57-year-old female patient with shoulder pain on the right-side was admitted through the emergency room following a car accident. Seven weeks before the accident, the patient had undergone surgery at a different hospital for the repair of supraspinatus tendon rupture on the right-side via suture bridge technique. Humerus surgical neck fracture was confirmed by X-ray, and proximal humerus fracture at the anchor site was confirmed by magnetic resonance imaging. Following 7 months of conservative treatment resulted in satisfactory bone union and motion of the shoulder joint. We report the need of close observation during and after the arthroscopic repair of the rotator cuff in patients with osteoporosis.

Spontaneous pneumomediastinum and subcutaneous emphysema are rare complications of labor, especially in the late pregnancy period, but they are usually self-limiting. Management includes avoidance of exacerbative factors and close observation with supportive treatment. A 19-year-old primi gravida at 36 weeks pregnancy presented with swelling over the right side of the face, neck and chest. Her general examination was normal. Systemic examination revealed swelling with palpatory crepitation over the right side of chest, neck and face, and other examination findings were normal. Chest X-ray revealed subcutaneous emphysema without pneumothorax. The patient left hospital against medical advice. Keywords: Pregnancy; subcutaneous emphysema; pneumomediastinum.

Background and Purpose: The upper extremities, especially the arms and shoulders, are used intensively in racquet sports. In this work, our primary aim is to compare bone mineral densities (BMDs) between dominant and non-dominant arms in racquet athletes. We then compare BMDs between athletes playing racquet sports and non-athletes. Methods: A total of 24 racquet sports male athletes active for at least 10 years (age, 22.46 ± 2.41 years) and 22 non-athletes (age, 21.45 ± 1.74 years) voluntarily participated in this study. The BMDs of the humerus, radius, and ulna of the dominant and non-dominant arms of both groups were measured by dual energy X-ray absorptiometry. Results: The BMDs of the proximal humerus and humeral shaft of dominant arms were significantly higher than those of non-dominant arms in athletes (19.85% vs. 12.02%); while statistically, no statistically significant difference in BMDs was found in non-athletes (P > 0.05). The BMDs of the dominant proximal humerus and humeral shaft of athletes were higher than those of non-athletes (P < 0.05). Non-dominant arm BMDs did not differ between the two groups (P > 0.05). Conclusion: BMD differences observed between the right and left arms of athletes indicate that, rather than confounding factors like genotype, right-/left-handedness, participation in racquet sports may influence BMDs in the related extremities.

Low temperature x-ray microanalysis (LTXM) of solid biological materials has been documented for Lemna minor L. root tips. This discussion will be limited to a demonstration of LTXM for measuring relative elemental distributions of P,S,Cl and K species within whole cells of tobacco leaves.Mature Wisconsin-38 tobacco was grown in the greenhouse at the University of California, Berkeley and picked daily from the mid-stalk position (leaf #9). The tissue was excised from the right of the mid rib and rapidly frozen in liquid nitrogen slush. It was then placed into an Amray biochamber and maintained at 103K. Fracture faces of the tissue were prepared and carbon-coated in the biochamber. The prepared sample was transferred from the biochamber to the Amray 1000A SEM equipped with a cold stage to maintain low temperatures at 103K. Analyses were performed using a tungsten source with accelerating voltages of 17.5 to 20 KV and beam currents from 1-2nA.

Perivascular epithelioid cell tumor (PEComa) is a rare mesenchymal neoplasm characterized by expression of both mela-nocytic and smooth muscle markers. Only 10 primary malignant lung PEComas have been reported up to date. We report a 59-year-old male who presented with a lung neoplasm, found during the routine X-ray examination. Preoperative CT-scan revealed the 3,5-cm-sized mass, located at the border of the upper, middle and lower lobes of the right lung. Patient underwent a thoracotomy, resection of the upper, middle and lower lobes of the right lung accompanied with mediastinal lymphadenectomy. After surgery, chylothorax was revealed. Conservative treatment was unsuccessful, so we performed laparoscopic clipping of the thoracic lymph duct. Patient was dismissed from hospital on the 10-th day after the second operation in good condition. In this report, we intend to increase the limited knowledge relating to natural history and optimal treatment of such a rare condition as a primary malignant lung PEComa.

Abstract BACKGROUND Low grade gliomas (LGGs) are the most frequent pediatric brain tumor and they comprise a variety of histologies. Complete surgery is curative but sometimes its location makes it difficult. Recent publications highlight the excellent long-term outcomes of patients with LGGs with complete and incomplete resected tumors. Current strategies are focused on reducing risks of treatment related sequelae. METHOD We describe a patient with a suspected LGG managed by close observation. We describe the case of a 6 year old female with 5 months history of focal onset seizures. During this time a brain MRI was requested and tumor was evidenced. After “tumor diagnosis” was made family visited a handful of private neurosurgeons with a uniformly dismal prognosis and high risk morbidity from procedures offered. When first seen at our Hospital, the clinical history seemed compatible with a LGG and seizures well controlled with antiepileptic drugs. Neurological examination was completely normal. MRI showed a large tumor (7x5x5 cm) hypointense on T1, hyperintense on T2, without contrast enhancement, involving the right temporal lobe white matter, insula, internal capsule, hipoccampus, thalamus and mesencephalus with middle cerebral artery encasement. Interval imaging was proposed and after 4.5 years since diagnosis the tumor has been stable and patient clinically excellent. CONCLUSION Overall survival in pediatric LGGs is excellent and risk of sequelae should always be part of multidisciplinary team considerations. In centers with significant neurosurgical morbidity, biopsy of large tumors that are compatible with LGG may not be required in selected cases.

An 8-month-old boy presented with right hemiplegia of sudden onset after 20 days of Kawasaki disease, which was not initially treated by gamma globulin. Cranial X-ray computed tomography confirmed cerebral infarction as the cause of the right hemiplegia. In subsequent weeks, he developed multiple thromboses in coronary aneurysms. He successfully underwent intracoronary thrombolysis using tissue plasminogen activator without haemorrhagic complications. Cerebral infarction as a complication of Kawasaki disease is rare, and is a difficult clinical situation to manage.

At birth, the transition to newborn life is triggered by lung aeration, which stimulates a large increase in pulmonary blood flow (PBF). Current theories predict that the increase in PBF is spatially related to ventilated lung regions as they aerate after birth. Using simultaneous phase-contrast X-ray imaging and angiography we investigated the spatial relationships between lung aeration and the increase in PBF after birth. Six near-term (30-day gestation) rabbits were delivered by caesarean section, intubated and an intravenous catheter inserted, before they were positioned for X-ray imaging. During imaging, iodine was injected before ventilation onset, after ventilation of the right lung only, and after ventilation of both lungs. Unilateral ventilation increased iodine levels entering both left and right pulmonary arteries (PAs) and significantly increased heart rate, iodine ejection per beat, diameters of both left and right PAs, and number of visible vessels in both lungs. Within the 6th intercostal space, the mean gray level (relative measure of iodine level) increased from 68.3 ± 11.6 and 70.3 ± 7.5%·s to 136.3 ± 22.6 and 136.3 ± 23.7%·s in the left and right PAs, respectively. No differences were observed between vessels in the left and right lungs, despite the left lung not initially being ventilated. The increase in PBF at birth is not spatially related to lung aeration allowing a large ventilation/perfusion mismatch, or pulmonary shunting, to occur in the partially aerated lung at birth.

We did this research to observe the effect of LIPUS on long bone fracture repair and caveolin-1, β-catenin signaling expression in the radius defects of rabbits, to explore its possible molecular mechanisms. 24 male New Zealand rabbits with bilateral radial bone defects were divided into 4 groups randomly, n = 6. The right side had daily LIPUS exposure for 20 minutes, while the left received sham treatment. After 7, 14, 21, 28 days, respectively, fracture healing was observed by X-ray imaging and Dual Energy X-ray Absorptiometry (DXA) scan, specimens were harvested for histology, immunohistochemistry, and gene expression analysis. We found that LIPUS brought forward endochondral ossification, increased the bone callus size without changes in Bone Mineral Density (BMD). The caveolin-1 expression increased first then decreased, while the β-catenin kept growing during the process. These demonstrated that caveolin-1 participated in fracture healing accelerated by LIPUS, which was speculated to play a dual role in β-catenin signaling expression.
