Gnathostomiasis has rarely been described outside endemic countries. We report on a series of 5 patients (4 females, 1 male, mean age 42.2 years) who returned to France from South-East Asia and presented with cutaneous gnathostomiasis. The cutaneous lesions appeared within a mean period of 62 d (range 10-150 d) after return. They consisted of creeping eruptions in 3 patients (in addition one also had papules, one had nodules and hepatitis, and one had hepatitis; all 3 had profound asthenia) and recurring migratory swellings in 2 patients. The mean eosinophil count was 1546/mm3 (range 398-3245/mm3). Diagnosis was based on positive serological tests in 3 patients and seroconversion in 2 patients, and was confirmed by identification of Gnathostoma hispidum in a biopsy specimen from one of the seropositive patients. Albandazole (1-4 courses) was given as treatment. Recurrences may occur up to 24 months after apparent cure without reinfection. Gnathostomiasis should be considered when patients return from tropical countries and present with migratory swellings or creeping eruption that does not respond to the usual treatment for cutaneous larva migrans. Serological tests may be negative initially and thus need to be repeated to check for seroconversion. Treatment may require multiple courses of albendazole and a prolonged period of follow-up is necessary before cure can be confirmed.

Self-expanding metal stents in the palliation of neoplasms of the cervical esophagus.

BACKGROUND/AIMS: Self-expanding metal stents (SEMS) represent a major advancement in the palliative treatment of dysphagia caused by neoplasms of the esophagus. Malignant cervical stenoses are a challenge for palliative techniques, due to their close relationship with the cricopharynx. METHODOLOGY: Six patients with a malignant stricture of the upper esophagus, within 2 cm of the cricopharyngeal muscle, were treated with a self-expanding metal stent. All patients had a circumferential squamous cell carcinoma histologically proven. Patients were intubated under general anesthesia, and the procedure was carried out under simultaneous endoscopic and fluoroscopic control. RESULTS: All patients had a remarkable improvement of dysphagia and none of them reported a foreign body sensation. In 3 patients, an insufficient expansion of the stent, detected 24 hours later, required a balloon dilation in two of them, whereas, for the third patient, it was necessary to introduce a second stent. Neoplastic in- and overgrowth occurred in 4 (67%) patients after 1, 2, 4 and 8 months, respectively. These complications were managed by placing a second stent in 3 patients; in the fourth patient, a neoplastic involvement of the cricopharynx did not allow for an endoscopic examination. Improvement of dysphagia was observed only in the patient who received a covered Cook-Z stent. In the other 2 patients, a percutaneous endoscopic gastrostomy was performed. The only major complication occurred in the patient who received three metal stents, as he complained of severe cervical pain. CONCLUSIONS: Our experience shows that uncovered self-expanding metal stents provide a good palliation in this subgroup of patients. Tumour ingrowth, overgrowth, and the progressive impairment of the swallowing mechanism due to a proximal submucosal infiltration remain complications difficult to solve.
