Do restrictive gender attitudes and norms influence physical and mental health during very young Adolescence? Evidence from Bangladesh and Ethiopia.

Adolescence is seen as a window of opportunity for intervention but also as a time during which restrictive gender attitudes and norms become more salient. This increasingly gendered world has the potential to profoundly influence adolescents' capabilities, including their physical and mental health. Using quantitative data on 6,500 young adolescents (10-12) from the Gender and Adolescence: Global Evidence (GAGE) program, this paper analyses the association between restrictive gender attitudes (RGAs) at the individual level and restrictive gender norms (RGNs) at the community level and physical and mental health in Bangladesh and Ethiopia.

Lymphoscintigraphic technique to image canine esophageal lymph nodes.

Current noninvasive methods of imaging esophageal lymph nodes have an accuracy, specificity, and sensitivity of 70%. Using a flexible esophagoscope, technetium-99m antimony sulfide colloid was injected in the esophageal submucosa of six dogs who then underwent nuclear scans to identify lymph-node location. The euthanized animals underwent dissection of cervical, thoracic, and abdominal lymph nodes.

Normal adult swallowing of liquid and viscous material: scintigraphic data on bolus transit and oropharyngeal residues.

Scintigraphic data are provided for 20 normal control subjects, 39-65 years of age. Each subject swallowed 10 cc of water and 10 cc of a more viscous material (1,100 centipoise) consisting of apple juice thickened with Thick-It, a commercial food thickener. The test substances were combined with 2.

Scintigraphic assessment of swallow efficiency postlaryngectomy.

There have been reports of a high incidence of hypopharyngeal stenosis in total laryngectomy patients when the surgery requires a partial pharyngectomy for pyriform sinus involvement. In this study, three groups were compared: total laryngectomy patients without partial pharyngectomy, total laryngectomy patients with partial pharyngectomy, and normal controls. All patients had received radiation therapy following surgery.

Splenic reimplantation does not affect outcome in chronic canine model.

The effects of septic insult were compared in a canine model of splenic reimplantation. Sequential changes in hematologic, hepatic, and immunologic function were monitored biweekly in 18 dogs during 10 months after splenectomy, splenectomy with reimplantation, or sham operation. There was no significant difference in these measures between the two groups.

Detection of canine allograft lung rejection by pulmonary lymphoscintigraphy.

We previously demonstrated that lymphoscintigraphy could be used to study pulmonary lymphatic flow. Radiocolloids, high-molecular-weight proteins tagged with radioactive markers, are injected percutaneously in the periphery of the lung. These molecules enter the lymph, are transported via lymphatic channels, and concentrate in the tributary hilar and mediastinal lymph nodes, where they can be visualized by nuclear scan.

Scintigraphic assessment of aspiration in head and neck cancer patients with tracheostomy.

Tracheopulmonary aspiration commonly occurs in patients with dysphagia related to head and neck cancer. Scintigraphic studies were performed in 280 patients with head and neck cancer; 33% of these patients had tracheopulmonary aspiration. A subgroup of 18 tracheostomized patients had a tracheostomy tube with a removable obturator, so they could be studied with the tracheostomy open or occluded.

Reestablishment of lymphatic drainage after canine lung transplantation.

The technique of pulmonary lymphoscintigraphy was used to evaluate pulmonary lymphatic flow and to assess reestablishment of lymphatic drainage after lung transplantation. A first group of six control dogs underwent percutaneous transthoracic injection of a radiocolloid into the periphery of the left upper and lower lobes. Radiocolloids are large molecules tagged with radioisotopes that are absorbed only through lymph and are concentrated in tributary lymph nodes.

Thrombosis in spinal cord injury.

Some traditional coagulation assays and several new molecular markers of hemostatic activation were measured in 37 patients with spinal cord injury (SCI). Twenty one of the patients (57%) developed deep vein thrombosis (DVT). The radiofibrinogen uptake test (RFUT) was used to diagnose DVT.

Scintigraphic quantification of pharyngeal retention following deglutition.

A procedure is described for quantifying the amount of bolus material retained in the pharynx after completion of a swallow, using radionuclide swallow techniques. Data are derived from scintigraphic time-activity curves. The procedure takes into consideration the differential attenuation of radioactivity through various regions in the body, and expresses the result as a percentage of the total radioactivity in the ingested bolus.

Intestinal neoplasm mimicking a Meckel's diverticulum on scintigraphic imaging.

A 33-year-old man presented with colicky, intermittent, midabdominal pain with nausea and vomiting. A Tc-99m pertechnetate abdominal scan was performed and revealed a focal area of increased uptake in the midabdomen associated with dilated proximal loops of small bowel. Surgery revealed a high-grade partial obstruction of the midportion of the jejunum secondary to an annular adenocarcinoma of the jejunum.

Objective assessment of swallowing function in head and neck cancer patients.

Swallowing function was evaluated with scintigraphy in 37 patients with head and neck cancer. The patients were examined before and during the course of either surgery, chemotherapy, and/or radiotherapy. A total of 118 scintigraphic studies were performed.

Modification of compensatory swallowing in a supraglottic laryngectomy patient.

Results are presented for repeated videofluoroscopic and scintigraphic examinations of a supraglottic laryngectomy patient, illustrating the successful use and later changes in a compensatory swallow. Issues in patient management are outlined, stressing the importance of interaction between radiologists and dysphagia therapists in the rehabilitation of such patients.

Scintigraphic findings in patients with shoulder pain caused by interleukin-2.

Interleukin-2 is receiving widespread interest as an immunotherapeutic agent in the treatment of certain cancers. Severe arthralgias recently have been reported as a significant side effect, and the cause of pain is unknown. Because interleukin-2 is an immune modulator, we reviewed the 99mTc-methylene diphosphonate scintigrams in nine patients who had developed shoulder arthralgias while receiving interleukin-2 for metastatic melanoma.

Aspiration in patients with head and neck cancer and tracheostomy.

Tracheopulmonary aspiration is a common occurrence in patients with dysphagia associated with head and neck cancer. We performed quantitative scintigraphic analysis of tracheopulmonary aspiration in 125 patients with head and neck cancer; 58 of these patients had a tracheostomy. Tracheopulmonary aspiration occurred in 58% of patients with a tracheostomy and in 23% of patients without a tracheostomy.

Pharyngeal transit time: assessment with videofluoroscopic and scintigraphic techniques.

The swallowing function of 31 normal and dysphagic subjects between the ages of 39 and 79 was tested with both videofluoroscopy and scintigraphy. Pharyngeal transit times for the pair of tests were compared. A statistically significant correlation of 0.

Detection and quantification of laryngotracheopulmonary aspiration with scintigraphy.

Aspiration is analyzed by a new scintigraphic technique and standard videofluoroscopy in 78 patients with head and neck pathology and neurologic disorders. When both methods are compared to clinical aspiration and a positive x-ray film of pneumonia, they appear to complement each other and provide a very accurate evaluation. Scintigraphy is a more sensitive method for detecting aspiration below the vocal cords and also provides for flow dynamics and a method of quantifying the amount of aspirated material.

Videofluoroscopic and scintigraphic analysis of dysphagia in the head and neck cancer patient.

This paper presents two advances in the evaluation of swallowing function which better define the swallowing processes in the head and neck cancer patient. Videofluoroscopy, improved by computer-assisted image analysis, provides more accurate information regarding oral and pharyngeal movement of structures. Radionuclide scintigraphy, a complementary technique, quantitates bolus flow (transit times) and the degree of aspiration.

Renal transplant rejection: sonographic evaluation in children.

The ability to detect renal rejection sonographically was studied in 42 pediatric renal transplant patients over a 33-month period. Sonography was not helpful in detecting rejection when the donor was less than five years of age. When the donor was over five years of age, a combination of sonographic findings allowed detection of rejection with a greater specificity than has been reported previously.

Computerized bone scan. A potentially useful technique to measure response in prostatic carcinoma.

Computerized bone scanning (CBS), a technique used to measure quantitative changes in bone scans, is described. Ten patients with histologically proven metastatic carcinoma of the prostate had sequential CBS performed. Good correlation was found between marked improvement in CBS (more than 50% average decrease in counts) and objective responses.

Value of positive myocardial technetium-99m-pyrophosphate scintigraphy in the noninvasive diagnosis of cardiac amyloidosis.

Ten consecutive patients with tissue-proven amyloidosis, seven of whom presented with congestive heart failure, were found to exhibit intense diffuse uptake of technetium-99m-pyrophosphate (Tc-99m-PYP) on cardiac radionuclide imaging. The patients exhibited echocardiographic and systolic time interval abnormalities suggesting combined restrictive and congestive cardiomyopathic changes. On M-mode echocardiograms, there was symmetrically increased thickness of the interventricular septum and left ventricular (LV) posterior wall in diastole (10 of 10), decreased fractional shortening of the LV minor axis diameter in systole (eight of nine), and decreased percent thickening of the LV minor axis diameter in systole (eight of nine) and LV posterior wall (10 of 10) in systole.

Quantitative assessment of femoral head involvement in Legg-Calvé-Perthes disease.

We have developed a method for determining the extent of avascularity of the capital femoral epiphysis in suspected Legg-Calvé-Perthes disease. The avascularity is expressed quantitatively as a percentage of the normal uptake of a radionuclide in the vicinity of the involved hip. In twenty-seven patients who had radionuclide scintigraphy this method was reliable in establishing an early diagnosis of Legg-Calvé-Perthes disease as well as in assessing the amount of involvement of the femoral head.
