Background: Numerous studies have shown an association between asthma and mental disorders. While elevated rates of asthma have been noted among psychiatric patients with anxiety disorders and post-traumatic stress disorder, several studies have found elevated rates of mental disorders among asthma patients. Such studies, however, have generally relied upon questionnaires and assessment by non-specialist physicians to diagnose mental disorders and asthma.

Objectives: To examine a possible association between asthma and psychiatric diagnoses in Israeli military recruits and soldiers.

Methods: In this cross-sectional study we compared the prevalence of mental diagnoses in asthmatic recruits and soldiers to that in non-asthmatic recruits and soldiers. A total of 195,903 recruits and soldiers were examined by Israel Defense Forces recruiting offices and fitness boards. Diagnoses of asthma were based on a pulmonologist's diagnosis, including spirometry at rest and exercise testing as indicated; diagnoses of mental disorders were based on examination by a psychiatrist.

Results: The prevalence of asthma was found to be 7.8% (current) and 9.8% (lifetime). The prevalence of mental disorders was 13.4%. Current asthma was associated with an increased likelihood of any mental disorder (OR = 1.20, 95% CI = 1.15–1.26), and specifically with mood and anxiety disorders (1.31, 1.19–1.46), introvert personality disorders (1.20, 95% 1.12–1.28) and adjustment disorder (1.43, 1.26–1.62). Lifetime asthma was associated with an increased likelihood of the same disorders, but the association was not as powerful.

Conclusions: The results validate the previously documented association between asthma and mental disorders, using a sample of unprecedented size and improved methodology. A multidisciplinary approach to asthma that incorporates mental health professionals in the treatment of poorly controlled asthma and perhaps of asthma in general is recommended.
 

Background: Thyroidectomy for goiter is a common surgical procedure performed in most hospitals in Israel. Both general and ear, nose and throat surgeons are familiar with thyroidectomy for cervical goiters. In about 1–15% of thyroidectomies, the goiter is intrathoracic and requires somewhat different management. This topic has not been reviewed in the literature recently.

Objective: To evaluate the clinical presentation, preoperative workup, surgical complications and risk of malignancy in retrosternal goiters.

Methods: We retrospectively reviewed the records of 75 patients who underwent thyroidectomy for retrosternal goiter in the General Thoracic Surgical Department of our institution during a 15 year period, January 1990 to January 2005.

Results: All the patients (41 women and 34 men) were symptomatic at presentation, with choking and dyspnea being the most common complaint. Computerized tomography scan of the neck and chest were obtained before the operation in 71 patients (95%). Ten patients (13%) had a previous partial thyroidectomy. A cervical approach was used in 68 patients (91%). Seven patients (9%) required median sternotomy to complete the operation. One patient (1.3%) died from postoperative respiratory failure. Transient recurrent laryngeal nerve palsy occurred in 5 patients (7%) and permanent RLNP[1] in 3 (4%). The incidence of transient and permanent hypoparathyroidism was 10% and 2.6% respectively. Sixty-six lesions (88%) were benign and 9 (12%) were malignant.

Conclusions: Choking and dyspnea are the most common presenting symptoms of retrosternal goiter. CT scan is an important component of the preoperative evaluation and operative planning. Surgical removal of the thyroid is the treatment of choice and most patients have symptomatic improvement following the operation. Since a substernal thyroidectomy may be technically different from cervical thyroidectomy, a surgical team familiar with its unique pitfalls should perform the procedure.

Amyloidosis is characterized by the extra-cellular deposition of abnormal insoluble fibrillar proteins in organs and tissues.
