Background: Patients with systemic sclerosis (SSc) are at increased risk for autoimmune thyroid diseases, but information regarding thyroid nodules and cancer in SSc is scarce.

Objectives: To evaluate the thyroid gland in patients with SSc at a single Israeli center.

Methods: Thyroid workup was conducted in consecutive SSc patients: thyroid-stimulating hormone (TSH), free thyroxine (fT4), anti-thyroid peroxidase, and anti-thyroglobulin antibodies, as well as thyroid ultrasound and fine needle aspiration (FNA) when appropriate.

Results: Fifty patients, mean age 51.3 ± 13.5 years (44 women) were evaluated. Ten were previously diagnosed with thyroid disease. Median TSH level was 2.0 (normal range 0.23–4 mIU/l) and median fT4 level was 1.0 (normal range 0.8–2.0 ng/dL). Among the 40 thyroid disorder-naive patients, 3 had subclinical hypothyroidism and 5 had positive anti-thyroid antibodies; 22 (44%) had 1–6 thyroid nodules, which were ≥ 1 cm in 12 (24%). Accordingly, six patients underwent FNA, and five were diagnosed as colloid nodules and one as papillary carcinoma.

Conclusions: New cases of clinically significant autoimmune thyroid disease were not detected in our cohort of patients with SSc. Nevertheless, almost half had thyroid nodules. The clinical significance of these findings and their relation to thyroid cancer remains to be determined.

Background: Acute focal nephritis is an inflammatory process of the renal parenchyma affecting principally the cortex of the kidney. It is considered a midpoint in the spectrum of upper urinary tract infections, ranging from uncomplicated pyelonephritis to intrarenal abscesses, and until recently the hyperechoic sonographic appearance of this lesion was considered uncommon.  

Objectives: To determine the relative prevalence of hyperechoic and hypoechoic sonographic appearance of focal renal lesions in patients with the clinical diagnosis of acute pyelonephritis and to correlate the findings with those of the color Doppler examinations.

Methods: We reviewed the sonograms of 367 patients hospitalized with the clinical diagnosis of acute pyelonephritis. The sonograms were reviewed for acute renal inflammatory changes. When a focal lesion was detected, we noted the echogenicity, side, form, location and color Doppler characteristics.

Results: Abnormal sonographic findings related to the infection were found in 78 cases. In 52 patients a focal lesion was diagnosed. Forty-seven focal lesions appeared hyperechoic related to the adjacent parenchyma. These lesions were more frequently located at the upper pole and were wedge-shaped in most of the cases. The areas appeared hypo/avascular on the color Doppler examination.

Conclusions: Our data suggest that the most common appearance of acute focal nephritis is an area of increased echogenicity in the parenchyma of the affected kidney.
 

Background: Osteoporosis is the most common human bone disease. It affects millions of persons throughout the world and its prevalence will increase as the population ages worldwide.

Objective: To assess Israeli physicians' attitudes and knowledge with regard to management of osteoporosis.

Methods: A questionnaire was mailed to 1,900 Israeli physicians concerning their attitudes to the management of osteoporosis, their prescribing habits, and their knowledge on the pharmacological treatment of the disease.

Results: Replies were received from 19% of the physicians. The respondents encouraged physical activity and cessation of smoking for all women, and prescribed estrogen replacement as the main treatment for 50-year-old women. A relatively low level of knowledge was found regarding the adequate dosage of several of the pharmacological treatments.

Conclusions: The findings of the present study stress the need to provide clear guidelines and to extend physicians' knowledge regarding the management of osteoporosis.
