Trapeziometacarpal osteoarthritis is associated with more pain and restrictions than other hand osteoarthritis due to the functional importance of the thumb. While the effectiveness of surgical and pharmacological interventions has been widely examined, there is a lack of specific evidence about conservative non-pharmacological trapeziometacarpal osteoarthritis therapies. The objective of this systematic review was to provide evidence-based knowledge on the effectiveness of physiotherapy and occupational therapy on pain, function and quality of life.. A literature search of Medline, CINAHL, PEDro, OTseeker, EMB Dare Cochrane Database of Systematic Reviews and Cochrane CENTRAL was performed. Randomized and quasi-randomized controlled trials and corresponding systematic reviews, observational studies, pragmatic studies and case-control studies were included. The risk of bias was assessed.. Physical and occupational therapy-related interventions, especially multimodal interventions, seem to be effective to treat pain in patients with trapeziometacarpal osteoarthritis. Pre-fabricated neoprene splints and custom-made thermoplastic splints may reduce pain equally. Single interventions seem not to be effective. Significant evidence for effectiveness on function and quality of life could not be found.. The sole Na. The SUV. Genetic variants of

Stent implantation in malignant bronchial stenoses is a highly effective method of providing symptomatic relief by restoring bronchial patency. Whether an improvement in ventilatory conditions is paralleled by an increase in blood flow and gas exchange has not yet been determined.. Fourteen patients with malignant, high-grade obstruction of bronchi who had metal stent implantation were investigated. Before the intervention and again 8 days afterward, both quantitative technegas ventilation and 99mTc-MAA perfusion scans (V/Q scans) and lung function tests were performed.. Stent implantation was successful in all patients, with a significant reduction in the degree of bronchial stenosis (pre-stent: 93% +/- 1.5%; post-stent: 16% +/- 3.5%). After stent implantation, ventilation scintigraphy revealed an improvement in tracer deposition by 65% (pre-stent: 37% +/- 8%; post-stent: 61% +/- 6%; p < 0.05) within the affected lung. A complementary increase of 71% by perfusion scintigraphy was obtained (pre-stent: 27% +/- 4%; post-stent: 46% +/- 5%; p < 0.01%). Based on scintigraphic criteria, stenting was successful in 93% (n = 13) of all patients. Lung function studies performed after the intervention showed significant improvement in vital capacity (VC, p < 0.01), forced expiratory volume in 1 sec (FEV1, p < 0.05), peak expiratory flow (PEF, p < 0.05), arterial oxygen (PaO2, p < 0.05) and carbon dioxide (PaCO2, p < 0.05) tension, and oxygen saturation (p < 0.05).. Stenting of malignant high-grade bronchial obstructions leads to an increase in bronchial patency and in activity distribution of both ventilation and perfusion scintigraphy of the affected lung, accompanied by significant improvement in lung function parameters.

Evaporation of Tc-99m pertechnetate at about 2500 degrees C on a carbon surface generates an ultrafine aerosol of Tc-99m-labeled carbon clusters (Technegas). The small particle size of about 100 nm enables the aerosol to behave similarly to a gas in its ability to penetrate. After inhalation, the radioactive particles adhere to the walls of the respiratory bronchioles and alveoli, or to the greater bronchial tubes if the airflow is not laminar. The high concentration of radioactivity in the argon carrier gas makes it possible to perform inhalation scintigraphy after only a few breaths. The authors investigated 24 infants with multiple events of bronchitis, most of whom had pneumonia. Seventeen patients had inhalation scintigraphy and bronchoscopy. Of these, 11 had scans diagnostic of bronchial stenosis and 6 had normal scans. Except for two pathologic scans, all scintigraphic findings matched well with the results of bronchoscopy. Seven patients had scintigraphy only, of which four were normal. Inhalation scintigraphy with Technegas is a reliable, nonhazardous procedure to preselect young patients for directed bronchoscopy.

A clinical study was done of 19 patients in our male infertility clinic, who were diagnosed as having a varicocele and showed atypical radionuclide accumulation in the dynamic image of scrotal scintigraphy. The semen quality was good in 26 percent and poor in 42 percent. Patients with severe congestion in the varicocele tended to be small in number. The dynamic images of the varicoceles were classified into two groups: one group with no radionuclide accumulation, and one group with patchy radionuclide accumulations. Surgical treatment was performed in patients with poor semen quality or with a long infertility period. Neither improvement in the semen quality nor impregnation was achieved postoperatively in patients who had shown no accumulation of the radionuclide in the dynamic imaging. In patients who had shown patchy radionuclide accumulations, the postoperative results were good. We concluded that preoperative dynamic imaging of scrotal scintigraphy is a good means of estimating the postoperative prognosis of fertility.

In recent years salivary gland scintigraphy has gained widespread acceptance as a useful means for evaluating salivary gland disorders. An absolute indication for this procedure exists when the ductal orifice of one or several major salivary glands cannot be found or cannot be cannulated. Clinical conditions in which this problem occurs include technical failure to probe and cannulate the duct, developmental anomalies, obstructive disorders, traumatic lesions and fistulae and the need of postsurgical information after glandular excision or after ligation or repositioning of a major excretory duct. The clinical value of scintigraphy in these conditions is demonstrated by means of case presentations.

Forty-one patients were evaluated with exercise-gated radionuclide ventriculography before and within 4 days after successful transluminal coronary angioplasty and 4 to 12 months later. Patients were subgrouped according to the degree of restenosis demonstrated angiographically at 4 to 12 months (Group I [n = 23]: less than or equal to 20%; Group II [n = 10]: greater than 20% but less than 50%; Group III [n = 8]: greater than or equal to 50%). Patients with abnormal findings on gated radionuclide ventriculography (less than 5 point increase in ejection fraction or wall motion deterioration) early after angioplasty were eventually found to have a greater degree of restenosis than were patients with normal findings (41.2 +/- 30.3 versus 19.0 +/- 25.4% restenosis, p less than 0.0001). The accuracy of abnormal radionuclide ventriculography in predicting 50% or greater restenosis was 73% immediately after angioplasty and 77% at the time of follow-up angiography. Gated radionuclide ventriculographic results were abnormal in 5% of Group I patients compared with 75% of Group III patients (p less than 0.01) early after angioplasty; at late follow-up, they were abnormal in 27% of Group I patients compared with 88% of Group III patients (p less than 0.01). Group I patients had a greater increase in ejection fraction than did Group III patients at early (+11.3 +/- 7.5 versus + 3.5 +/- 6.5 points, p less than 0.01) and late (+11.8 +/- 7.8 versus -1.9 +/- 8.7 points, p less than 0.0005) follow-up. It is concluded that gated radionuclide ventriculography is useful in predicting coronary restenosis after transluminal coronary angioplasty.

Four men with clinical features of superior vena caval syndrome due to large substernal non-toxic multinodular goitre have undergone radionuclide superior vena caval studies. In all cases the dynamic scintigraphs showed a characteristic thyroidal configuration attributed to the definition of stretched thyroidal veins and their tributaries. Radiocontrast studies of two patients demonstrated the characteristic thyroid configuration. A radionuclide superior venacavogram taken post-thyroid lobectomy in one case showed the features had reverted to normal.
