Background: Primary hyperparathyroidism in elderly patients is usually associated with additional co-morbidity that increases operative risk, and thus many geriatric patients are denied the benefit of surgery for a single parathyroid adenoma.

Objectives:  To evaluate the safety and efficacy of accurate single photon emission computed tomography sestamibi scintigraphy, enabling precise localization of a single adenoma, in the geriatric population

Methods: Twenty-two patients aged 70 years and over with biochemically proven PHPT[1] and with a single parathyroid adenoma identified by localization studies (sestamibi SPECT[2] scan and ultrasonography) underwent 23 operations over 29 months (out of a total of 140 patients operated upon during the same period). Immediate preoperative sestamibi scintigraphy and marking of focal adenoma uptake followed by intraoperative hand-held gamma probe were used for the removal of the parathyroid adenoma by unilateral minimal access surgery. Associated major co-morbid conditions and pre- and postoperative calcium, phosphorus and parathormone levels were recorded. Indications for surgery were listed and operative and postoperative complications were noted. The patients were followed for a mean period of 17.7 months using the same parameters.

Results: The 22 patients with PHPT had a mean age of 76.3 ± 5.9 years (range 70–88 years)  and a female to male ratio of 13:9. Associated co-morbidity included ischemic heart disease (n=15), hypertension (n=22), non-insulin-dependent diabetes mellitus (n=9), chronic obstructive pulmonary disease (n=3), and previous neck surgery (n=3). Mean preoperative serum calcium, phosphorous and PTH[3] were 11.7 ± 1.3 mg/dl, 2.5 ± 0.5 mg/dl and 160.9 ± 75.4 pg/ml respectively. In 20 of the 22 patients, surgery was successful in curing PHPT (91%). One patient had persistent hypercalcemia due to a missed adenoma, and repeat operation (by focused minimal access surgery) was successfully performed 2 weeks later. There were no complications and no morbidity postoperatively. Mean postoperative serum calcium, phosphorous and PTH were 9.6 ± 1.2 mg/dl, 3.0 ± 0.5 mg/dl and 35.2 ± 24 pg/ml respectively. In all patients, serum calcium levels remained normal (9.7 ± 1.3 mg/ml) after long-term follow-up (mean 17.7 ± 9.6 months).

Conclusions: Minimally invasive, radio-guided focused parathyroidectomy for a single adenoma is a safe and effective method to cure hyperparathyroidism in the elderly. Success of surgery is directly related to the surgeon's experience and to the precise localization marking provided by sestamibi scintigraphic SPECT localization and concurrent sonographic findings.

Background: With the aging of the population and the increase in the number of elderly patients under the care of primary care physicians in the community, it is essential that the physician be aware of the preventive medicine recommendations for this group of patients. Accepted evidence-based guidelines have been developed for the older patient and adherence to these guidelines may play a significant role in decreasing morbidity and mortality in the elderly.

Objectives: To determine whether elderly patients in community clinics are aware of the preventive medicine practices that are relevant and available to them, and to assess which factors influence their decision to use such interventions. Of particular interest was to evaluate the role of the doctor-patient relationship on the degree of patient compliance with preventive procedures.

Methods: Patients attending community clinics of the Clalit Health Services in Jerusalem were interviewed. Background information was obtained and the patients were questioned regarding the use of the following preventive medicine recommendations: screening for occult blood in the stool, testing of vision and hearing, influenza and pneumococcal immunization, thyroid-stimulating hormone testing, digital rectal examination for prostate cancer, and calcium supplementation. The patients were questioned regarding the use of aspirin or oral anticoagulation where relevant. Factors influencing their level of compliance were examined.

Results: The study group comprised 205 patients with an average age of 74.5 years. Overall the rates of compliance were high, with 78% undergoing visual assessment, 87% fecal occult blood testing, and 81% influenza immunization. Pneumococcal immunization had been administered to 49% of those interviewed and 56% had their hearing tested. Digital rectal examination had been performed in 45% of patients. Calcium supplementation was used in 60% of patients. Almost all the patients (91–100%) noted that the physician had initiated the procedure and that non-compliance was due to patient preferences. Of the 172 patients who were assumed to benefit from aspirin use, 153 (89%) used the medication, and 87% of 23 patients with atrial fibrillation were on chronic anticoagulation.

Conclusions: A high level of compliance with preventive medicine recommendations was found among this group of elderly patients. The doctor-patient relationship had a positive effect on the patients' compliance.
 

Background: Hepatis C virus infection is presently an exclusion criterion to classify SjoÈ gren's syndrome; however, there are distinct clinicopathologic and biologic similarities between HCV-related and SS-related chronic inflammation of mucosa-associated lymphoid tissue and lymphoproliferation that suggest common pathogenetic pathways.

Objectives: To determine whether a subset of patients with sicca syndrome and HCV infection may present a true primary SS rather than a distinct clinicobiologic entity.

Methods: We extensively characterized 20 consecutive patients with positive anti-HCV antibodies and heavy subjective dry eye and/or dry mouth symptoms, plus positive unstimulated sialometry and/or Shirmer's test. We then compared these features with those in HCV-negative primary SS controls (classified according to the latest American-European Consensus Group Classification Criteria for SS).

Results: Of the 20 HCV-positive patients with sicca manifesta-tions, 12 (60%) had positive anti-SSA/SSB antibodies (3/12 by enzyme-linked immunosorbent assay and 6/12 by immunoblot) and/or positive salivary gland biopsy (at least 1 focus/4 mm2), which met the strict classification criteria for SS, as in the case of HCV-negative SS controls. Comparing the HCV-positive SS subset with HCV-negative SS controls showed similar female to male ratio (11/1 vs. 46/4), major salivary gland swelling (17% vs. 26%), positive antinuclear antibodies (75 vs. 94%) and positive rheumatoid factor (58 vs. 52%). Significant differences (P< 0.05) were seen in mean age (69 vs. 56 years), liver disease (50 vs. 2%), lung disease (25 vs. 0%), anti-SSA/SSB positivity (25 vs. 90%), and low C3 or C4 (83 vs. 36%). HCV-positive SS patients exhibited a trend for more frequent chronic gastritis (50 vs. 22%), fibromyalgia (33 vs. 14%), peripheral neuropathy (33 vs. 18%), purpura (33 vs. 19%) and cryoglobulinemia (33 vs. 6%).

Conclusions: A major subset of HCV-positive patients with definite subjective sicca symptoms and positive objective tests may indeed present a true, though peculiar, subset of SS. There are strict similarities with key clinical, pathologic and immunologic findings of definite HCV-negative SS. Other features appear more characteristic of HCV infection. When also considering that HCV is sialotropic and may be treated, HCV-related chronic sialadenitis represents a unique opportunity to clarify key pathogenetic events occurring in the large majority of HCV-negative SS; and similarities to typical primary SS, rather than differences, should be taken into account.
 

Background: Guidelines are important for keeping family physicians informed of the constant developments in many fields of medicine.

Objectives: To compare the knowledge of gastroenterologists and family physicians regarding the diagnosis and treatment of gastroesophageal reflux disease in order to determine the need for expert guidelines.

Methods: A 25 item questionnaire on the definition, diagnosis and treatment of GERD[1] was presented to 35 gastroenterologists and 35 family physicians. Each item was rated on a four point scale from 1 = highly recommended to 4 = not recommended. A voting system was used for each group on separate occasions. The proportions of correct answers according to the level of recommendation were compared between the groups.

Results: The groups' responses agreed on only 4 of the 25 items; differences between the remaining 21 were all statistically significant. For 14 items, 70% of the gastroenterologists chose the grade 1 recommendation, whereas more than 70% of the family physicians chose mostly grade 2.

Conclusions: The gap in knowledge on gastroesophageal reflux disease between gastroenterologists and family physicians is significant and may have a profound impact on diagnosis and treatment. Clear and accurate guidelines may improve patient evaluation in the community.

Background: The threat to the individual’s physical integrity and well-being as well as to those of significant others, the disruption of normal patterns of life, and property losses make wartime a highly stressful condition.

Objectives: To assess the level of psychological distress in primary care attenders in a district of Jerusalem (Gilo) that experienced long-term exposure to gunfire.

Methods: A self-administered questionnaire exploring emotional distress (anxiety and depression symptoms), fire exposure, patterns of help-seeking behavior, and prescription of sedative or hypnotic drugs was administered to a sample of 125 consecutive attenders to a general practitioner during a 10 week period in the autumn of 2001. Eighty-four attenders residing in Gilo were compared with 41 attenders residing in neighborhoods that had not been under fire. T-tests and Mann-Whitney two-sample tests were used to determine statistical significance of differences.

Results: The mean distress score was significantly higher among the Gilo residents than among their counterparts in other neighborhoods (1.1 ± 0.8 vs. 0.8 ± 0.5, t = 1.73, P <0.01); 15.5% of the former reported probable clinically significant distress. Emotional distress was associated with periods of intensive gunfire exposure, psychological care-seeking behavior, and the prescription of sedative or hypnotic drugs. No significant differences in distress levels were found between those living in zones of Gilo that were at differential gunfire risk, nor between those whose houses and cars were or were not damaged.

Conclusions: War-related life events would seem to be associated with elevated emotional distress. A motivated primary care physician could easily and reliably ascertain the attenders’ psychological status and identify those requiring psychological support. These identification and intervention stages are facilitated if the specialized services are community-based.

Background: Primary care physicians' adherence to accepted asthma guidelines is necessary for the proper care of asthma patients.

Objectives: To investigate the compliance of primary care physicians with clinical guidelines for asthma treatment and their participation in related educational programs, and to evaluate the influence of their employment status.

Methods: A questionnaire was administered to a random sample of 1,000 primary care practitioners (pediatricians and family physicians) in Israel.

Results: The response rate was 64%. Of the physicians who participated, 473 (75%) had read and consulted the guidelines but only 192 (29%) had participated in an educational program on asthma management in the last 12 months. The younger the responding physician (fewer years in practice), the more likely his/her attendance in such a program (P<0.0001). After consulting the guidelines 189 physicians (40%) had modified their treatment strategies. Significantly more self-employed than salaried physicians had read the guidelines and participated in educational programs; physicians who were both self-employed and salaried fell somewhere between these groups. This trend was not influenced by years in practice.

Conclusions: All primary care physicians should update their knowledge more often. The publication of guidelines on asthma must be followed by their proper dissemination and utilization. Our study suggests that major efforts should be directed at the population of employed physicians.
