Hypopharyngeal perforation from a swallowed fork: a brief report and comment.

Hypopharyngeal perforations are usually seen as a complication of endotracheal intubation by less experienced physicians in emergency situations. The site most commonly perforated is the pharynx, posterior to the cricopharyngeal muscle; the second most common site is the pyriform sinus. We report here an unusual cause of hypopharyngeal perforation from a swallowed plastic fork in a psychiatric patient.

Iron content of native foods.

Chemical analysis showed that some foods cooked in a cast iron pot gained significantly in iron content. This was particularly so for rice and green vegetables, but not for the major root staples of Papua New Guinea. It therefore seems unlikely that a campaign to encourage the use of iron pots for cooking would significantly increase the iron content of diets in Papua New Guinea to an extent which would mitigate the high prevalence of iron deficiency.

Iron overload in Sub-Saharan Africa: to what extent is it a public health problem?

Excessive deposition of Fe in the organs and tissues of Sub-Saharan Africans was first described in South Africa in 1929. Fe overload, or siderosis, was initially attributed to infections and to metallic poisoning (Cu, Sn, Zn), and then to malnutrition. In 1953 it was hypothesized that it was due primarily to excessive Fe intake derived from foods and drinks prepared in Fe vessels. Recently, in 1992 it was advanced that a gene distinct from any HLA-linked locus may also play a role. As to sequelae, in early research on series of hospital patients, the condition was linked to scurvy, osteoporosis, diabetes, cirrhosis, and latterly, to hepatocellular cancer and tuberculosis. Accordingly, many have concluded that Fe overload is responsible for considerable morbidity and mortality, that adventitious Fe intake should be reduced, and that phlebotomy be recommended for those severely affected. However, there are numerous limitations in the evidence. There are also problems in interpretation, since levels of Fe in the serum are affected additionally by a variety of factors: infection, inflammation, certain cancers and alcohol intake. These considerations complicate attempts to assess to what extent the associations described denote causation, and whether Fe overload has significant ramifications for ill in the general African population. While the adverse sequelae of overload may be less of significance than many believe, the precise pathogenicity of the phenomenon will remain uncertain until further investigations, including prospective studies, are undertaken.

[Lead elimination by traditional curing].

OBJECTIVE: To evaluate traditional acidic curing as a preventive method for reducing lead content of glazed ceramic ware. MATERIAL AND METHODS: In 27 ceramic ware pieces from four states in Mexico, the level of residual lead was determined through atomic absorption spectrophotometry after four washings with acetic acid 3%. RESULTS: The lead content of the vinegar washing diminished proportionally with the number of washings, although it remained highly above the permissible levels of this metal (2.5-7.0 p.p.m.). CONCLUSIONS: Traditional acidic curing of glazed ceramic ware is not a useful preventive measure for reducing lead exposure.
