[The side effects of phlebography of the lower extremities using iohexol. A prospective study].

In this prospective study 463 consecutive outpatients, who had undergone phlebography because of clinically suspected deep venous thrombosis (DVT) were examined with clinical follow-up and impedance plethysmography to evaluate the rate of contrast media complications. Seventy-nine patients had immediate and mild side effects, and one had moderate side effects (bronchospasm); no patient suffered from severe life-threatening conditions. There was only one case of DVT which occurred after an initially negative phlebography. In a subgroup of 40 patients, who underwent iodine-125-fibrinogen scanning after phlebography, the study was positive in 9 cases. None of them presented with any evidence of DVT at follow-up phlebography. Contrast phlebography with iohexol is a safe and comfortable procedure. Low-osmolality nonionic contrast media are well tolerated by the patient.

Pollen, mite and mould samplings by a personal collector at high altitude in Nepal.

The new personal portable sampler for detection of environmental biologic particles (Partrap FA52, Coppa, Biella, Italy) was used to evaluate both atmospheric and indoor biologic particles in bedding at high altitudes during two Italian scientific expeditions in Nepal, in 1994 and 1996 respectively. The sampling was performed outdoors and indoors at the following altitudes: Katmandu 1,330 meters (m), LuKla 2,800 m, Namche 3,500 m, Pericle 4,200 m and Piramide 5,050 m. In both expeditions each sample of outdoor and indoor air was obtained by sucking air into the sampler either against the wind during a 6-h period, from 9 am to 3 pm, or from bedding of inhabitants resident at the different altitudes for 5 min. The number of pollens, moulds and mites trapped in each sample were assessed. The statistical analysis of the results by Spearman correlation test revealed a significant inverse correlation (p < 0.02) between altitude and the number of the considered biologic particles for sampling carried out during both the 1994 and 1996 expeditions. Moreover, Wilcoxon paired test showed no significant difference between the biologic sampling obtained in the two expeditions. These results confirm the decrease of the environmental biologic charge in relation to the increase of altitude and prove the efficacy of Partrap FA52 in obtaining reproducible quantitative data.
