RESUMEN
Impacted foreign bodies in the esophagus can result in respiratory symptoms including stridor and aphonia. Several mechanisms have been proposed to explain these symptoms, but the possibility of vocal cord paralysis and its cause has not been adequately emphasized. Two cases of young children with esophageal foreign body are described; both presented with respiratory symptoms, 1 with aphonia and the other with stridor. In both cases, the symptoms were secondary to vocal cord paralysis. A possible mechanism of recurrent nerve injury is proposed.

OBJECTIVE: To determine whether there is a seasonal peak onset of systemic juvenile rheumatoid arthritis (SOJRA) suggestive of an infectious etiology. We examined the seasonal variability of SOJRA in Israel. METHODS: A multicenter retrospective chart review of 59 patients with SOJRA, enrolled from 10 rheumatology units or pediatric departments in Israel. All patients met defined criteria of SOJRA. RESULTS: Fifty-nine patients (31 female, 28 male) were followed from 1982 to 1997. Their mean age was 7.1 +/- 4.3 years (range 0.9-16). Forty-six were Jewish and 13 were Arabs or of Bedouin origin. Eighteen patients (31%) had disease onset in the winter, 16 (27%) in the spring, 12 (20%) in the summer, and 13 (22%) in the fall. Twenty-eight patients had a monophasic disease subtype, while 31 had a chronic or cyclic subtype. The seasonal onset in the patients with the monophasic type versus the chronic or the cyclic type shows 7 versus 11 in the winter, 7 versus 9 in spring, 8 versus 4 in summer, and 6 versus 7 in fall, respectively. CONCLUSION: There is no seasonal pattern to SOJRA disease onset in Israel. However, the disease onset of patients having the chronic or the polycyclic subtype tends to be more common in winter and spring. Since patients with this type have more severe disease, it is possible that another specific infectious agent is one of the factors involved in the pathogenesis of the disease. Larger sampling and multicenter studies are required to clarify this point.
