Background: A high incidence of abnormal pulmonary function tests has been reported in cross-sectional studies among patients with rheumatoid arthritis. Few patients have been enrolled in longitudinal studies.

Objectives: To perform PFT[1] in rheumatoid arthritic patients without pulmonary involvement and to identify variables related to changes in PFT over 5 years of follow-up.

Methods: Consecutive RA[2] patients underwent PFT according to American Thoracic Society recommendations. All surviving patients were advised to repeat the examination 5 years later.

Results: PFT was performed in 82 patients (21 men, 61 women). Their mean age was 55.7 (15.9) years and the mean RA duration was 11.1 (10) years. Five years later 15 patients (18.3%) had died. Among the 67 surviving patients, 38 (56.7%) agreed to participate in a follow-up study. The initial PFT revealed normal PFT in only 30 patients (36.6%); an obstructive ventilatory defect in 2 (2.4%), a small airway defect in 12 (17%), a restrictive ventilatory defect in 21 (25.6%), and reduced DLco in 17 (20.7%). Among the 38 patients participating in the 5 year follow-up study, 8 developed respiratory symptoms, one patient had a new obstructive ventilatory defect, one patient developed a restrictive ventilatory defect, and 5 patients had a newly developed small airway defect. The DLco had improved in 7 of the 8 patients who initially had reduced DLco, reaching normal values in 5 patients. Over the study period a new reduction in DLco was observed in 7 patients. Linear regression analyses failed to identify any patient or disease-specific characteristics that could predict a worsening in PFT. The absolute yearly decline in forced expiratory volume in 1 sec among our RA patients was 47 ml/year, a decline similar to that seen among current smokers.

Conclusions: Serial PFT among patients with RA is indicated and allows for earlier identification of various ventilatory defects. Small airways disturbance was a common finding among our RA patients.

Background: Road traffic accidents are the leading cause of accidental injury and death for persons under the age of 35. The medical literature presents surprisingly little information on the general characteristics of such accidents in the urban setting.

Objectives: To characterize RTA[1] patients arriving at an urban trauma center.

Methods: We prospectively examined the charts of all patients admitted to the Tel Aviv Sourasky Medical Center due to RTA injuries during two periods in 1995.

Results: Of the 1,560 patients examined, the male:female ratio was 1:1 and median age was 27 years (47% aged 20–30 years); 51% of the accidents took place between 8 a.m. and 4 p.m. and on working week days; automobiles comprised 47.1% of the vehicles involved, motorized two-wheel vehicles 37.1%, bicycles 3.8%, and pedestrians 12%. The Glasgow Coma Scale was 15 on arrival in 98.7% of the patients. The trunk was the most commonly injured body part (84.7%); whiplash injury to the neck was diagnosed in 343 patients (22%), and brain concussion in 183 (11.7%). Computed tomography studies were performed in 34 patients (2.2%). The vast majority of patients (1,438, 92.2%) was discharged home; 14 (0.9%) were admitted to the intensive care unit, and 2 (0.13%) died during hospitalization. The average time spent in the emergency department in the morning shift was 2.1 hours.

Conclusions: We could identify distinguishing factors of this population: equal gender distribution, peak RTA incidence in the young adult working population during working hours, automobile drivers being the most injured subgroup, a disproportionate number of motorcycle and motor scooter involvement, and a relatively extensive amount of time and resources spent treating these injuries despite their generally minor nature.

Background: Dizziness and vertigo can be a complaint in various psychiatric conditions, where it usually constitutes only one of the features of the syndrome. Lately, a somatoform disorder characterized by almost mono-symptomatic dizziness and unsteadiness has been described. Since phobic postural vertigo usually presents without anxiety or other psychological symptomatology, patients with this condition seek help at neurologic and otolaryngologic clinics where they are often misdiagnosed as suffering from organic vertigo.

Objectives: To present the clinical features of 55 consecutive patients diagnosed with phobic postural vertigo at our clinic during 1998–2002.

Methods: We conducted a retrospective review of patients’ medical records and report two typical cases as illustration.

Results: The patients presented with complaints of unsteadiness with or without dizziness, and attacks of sudden veering that caused them to grasp for support. Accompanying anxiety was admitted by only 5% and vegetative symptoms were reported in 18%. In 16% the symptoms resulted in avoidance behavior. A stressful life event or an unrelated somatic disease triggered the onset of PPV[1] in 35% of patients, whereas a vestibular insult preceded the symptoms in 13%. The mean duration of symptoms was 26.7 ± 39.1 months (range 0.5–20 years). In 72% of patients the symptoms resolved after the psychological mechanism of their symptoms were explained to them; 24% improved with antidepressant treatment (selective serotonin reuptake inhibitors or tricyclic antidepressants), and only in 4% did the symptoms persist.

Conclusions: Since PPV is a frequently encountered diagnosis at some specialized dizziness clinics, familiarity with this entity resulting in early diagnosis can avoid unnecessary examinations and lead to effective treatment.
