Conclusion Several quality-control measures take place before (patient and camera preparation) and during SPECT acquisition to achieve
high-quality images. Not uncommonly, technologists and physicians are left with suboptimal images that have to be addressed
to reach the “right answer” for patient diagnosis and hence management. In many cases patients may be reimaged, especially
if the problem is detected early, but in other cases either the patient has left the nuclear laboratory or there is an inevitable
problem that, even with reimaging, will not be resolved. In these situations the technologist and physician have to seek the
available techniques to obtain the best images possible. These resources are discussed in this issue as an aid in quality
control to obtain the best possible images. 相似文献

Tuberculosis involving the soft tissue from adjacent bone or joint is well recognized. However, primary tuberculous pyomyositis, tuberculous bursitis, and tuberculous tenosynovitis are rare entities constituting 1% of skeletal tuberculosis. Tuberculous tenosynovitis involves most commonly the tendon sheaths of the hand and wrist, and tuberculous bursitis occurs most commonly around the hip. The greater trochanteric bursa and the greater trochanter are the most frequent sites of tuberculous bursitis. Cases of primary tuberculous pyomyositis and tenosynovitis of the tendons of the ankle and foot are seldom reported in the radiology literature. All imaging modalities-plain radiography, bone scan, computed tomography, and magnetic resonance imaging (MRI)--provide information that is helpful in determining therapy. MRI in particular, with its multiplanar capabilities and superb contrast of soft tissue, can demonstrate the extent of the soft tissue mass and access the adjacent bones and joints. However, MRI has no diagnostic specificity in regard to tuberculosis, and in nonendemic areas, biopsy is strongly recommended. All patients in this review were permanent residents of North America or Western Europe and were immunocompetent. Examples of atypical presentations of the above entities are demonstrated. 相似文献

Rabbits are the experimental animals of choice in many studies including flaps, wounds, and topical trials for new pharmacological
agents. Because the topical drugs and other materials used for dressing are irritating to the animal, they tend to remove
dressings, bandages, drapes, insensate flaps, and also topical drugs by scratching, licking, and biting if they are within
the reach of the animal. In this study, we report an easy to prepare, user-friendly, comfortable, and cheap dressing protector
called a dressing shield to prevent these problems. 相似文献

We report the results of administration of danazol after suspension of
gonadotrophin-releasing hormone analogue (GnRHa) therapy for uterine
myomas. A total of 21 women with uterine myomas was treated with 100 mg
danazol for 6 months after GnRHa therapy. Uterine volume and endocrine
status were monitored monthly by ultrasound and assay of plasma
gonadotrophins, oestradiol and progesterone. The results show a rebound of
uterine volume about 30% less than in controls at the end of danazol
therapy. Menstrual cyclicity returned after 65 +/- 3 days in 16 subjects
and five patients remained amenorrhoeic. Hormone assays confirmed renewed
ovarian function in the women whose menstrual periods returned. Bone
mineral content was substantially reduced during GnRHa treatment but
improved significantly during danazol therapy even in the women who
remained amenorrhoeic. These results show the utility of danazol in
prolonging the therapeutic effects of GnRHa. The mechanism by which danazol
inhibits rebound of uterine volume may be due to its antiprogesterone
effects on uterine myomas.

An indirect competitive ELISA was developed for the quantitative analysis of aldrin/dieldrin. This has been used to monitor the levels of these pesticides in water samples collected in Egypt. The detection range of the aldrin/dieldrin assay in water was 5–10 ppm without enhancement. River Nile water samples and tap water samples (n = 25) were collected from 25 stations in 16 different governorates in Egypt. Pesticides were detected in 10 of the 25 Nile water samples (40%) at levels from 10 to 110 ppb. In tap water samples, pesticides were not detected at levels greater than the lower limit of the assay. The technique described provides a rapid, economical, highly sensitive and specific method of analysis that is relatively simple to perform and interpret. It will be extremely useful in monitoring levels of pesticides in water used for human consumption. 相似文献

The efficacy and safety of a single nocturnal dose of famotidine (40 mg) was evaluated in 30 consecutive patients of duodenal ulcer (DU). Three patients were lost for follow-up and therefore were excluded. The mean age of remaining 27 patients was 34.3 (+/- 9.9) years and male to female ratio was 8:1. The mean size of the DU was 1.21 (+/- 0.79) cm. After a 4-week therapy all patients showed significant improvement and repeat endoscopy in 24 out of 27 patients (89%, 95% confidence interval; 78% to 100%) showed healed ulcer. Clinical assessment of pain relief at 4-week showed significant drop in the mean score of baseline daytime (from 1.85 to 0.13) and baseline nocturnal pain (from 1.70 to 0.10) (p less than 0.0001 and less than 0.0001, respectively). Also shown was the significant decrease in the mean gastrointestinal symptoms score from 5.89 at baseline to only 0.89 at 4-week (p less than 0.0001). Despite that all those who failed to show ulcer healing at 4-week were smokers, logistic regression analysis could not identify smoking or any other risk factors as adverse predictors of ulcer healing. None of the patients experienced significant side effects or adverse reactions. We conclude, that a single nocturnal dose of famotidine is a practical, highly effective and safe approach for the management of DU. 相似文献
