Hand, foot and mouth disease.

Standardisation is vital if the clinical images are to be used for monitoring any changes in the patient's condition. The two images can be cut and mounted in one 35 mm mount for comparison.

Protective effect of interferon on infections with hand, foot, and mouth disease virus in newborn mice.

The protective effect of interferon on infection with coxsackievirus type A 16 (CA-16) or enterovirus type 71 (EV-71) in newborn mice was examined. Subcutaneous administration of murine interferon (MuIFN-alpha/beta) into the infected mice produced a protective effect against infection with CA-16 or EV-71. It was found that the time of administration of MuIFN was important in relation to the cycle of infection. Protection was observed when MuIFN was given once daily for several days, from one day before or after infection with the lethal dose of CA-16 or EV-71. These results suggest that interferon may directly suppress infection with CA-16 and not indirectly suppress it by the medium of macrophages, natural killer cells, and T cells.

Hand, foot and mouth disease: University Malaya Medical Centre experience.

The prevalence of HFMD as well as the causative agents was unknown in peninsular Malaysia prior to May 1997. From May 1997 to June 2001, 585 patients suspected to have enterovirus infections, with 467 patients clinically diagnosed as having HFMD, were investigated in the diagnostic virology unit of the University Malaya Medical Centre. Data from this study showed that HFMD is endemic in Malaysia with the occurrence of two outbreaks during the study period. In each outbreak, a number of viruses were isolated but enterovirus 71 was the main virus isolated in both outbreaks. Echovirus 7 (Eo7) was isolated from 5 patients with HFMD in the second outbreak, a clinical entity that has not been attributed to it previously. Children aged 4 years and below, particularly those between 1 and 2 years of age, were in the main group of patients affected by the illness. HFMD by itself and without neurological involvement was relatively benign and self-limiting. There was no significant difference in the virus isolation rate with respect to gender and ethnic groups. Virus isolation was attempted in a total of 764 clinical specimens consisting of 342 stool specimens, 285 oral secretions specimens and 137 vesicular fluid specimens. Oral specimens gave the highest virus isolation rate (33.3%) followed by vesicular specimens (27.0%). Stool specimens only yielded an isolation rate of 14.0%.

The expanding panorama of split hand foot malformation.

The split hand/foot malformation is a developmental defect of the extremities resulting from errors in the initiation and maintenance of the apical ectodermal ridge. The phenotype is genetically heterogeneous, and it can be identified either as an isolated phenotypic manifestation or as a constituent component of a malformation syndrome. This overview describes the clinical phenotype, related animal models, and the evolving genetic heterogeneity of the malformation.

[Therapy of hyperhidrosis with tap water iontophoresis. Positive effect on healing time and lack of recurrence in hand-foot eczema].

Hyperhidrosis is due to an overfunction of eccrine glands (triggered by the autonomous nervous system) and may be a cofactor for palmoplantar eczema (dermatitis). Tapwater iontophoresis was used in 54 patients with hyperhidrosis manuum et pedum. After 10 applications directed by the dermatologist, 89% of patients noted an improvement in their hyperhidrosis. 20 patients suffering from palmoplantar eczema (dermatitis) who continued the treatment at home for at least 6 months were compared with a historical sex- and age-matched group of 20 eczema-patients without iontophoresis: The factors evaluated were the time needed for clearing and the relapse-free interval. Though iontophoresis-treated patients had a slightly faster clearing, this was statistically not significant (20 vs. 22.3 days; p > 0.05). However, the difference for relapse-free interval between the two groups was statistically highly significant (24.8 weeks vs. 8.35 weeks; p < 0.0001). Tapwater iontophoresis seems to be effective not only to control sweating. According to recently published data, galvanization seems to have a capsaicin-like effect as well. Our hypothesis is therefore, that galvanization with tapwater iontophoresis interrupts the neurogenic inflammation and prolongs the relapse-free interval in hyperhidrotic palmoplantar eczema (dermatitis).
