Skin problems after a tsunami

BACKGROUND: On December 26, 2004, the biggest earthquake for 40 years, measuring 9.0 on the Richter scale, triggered a tsunami that pounded the coastal areas of South Asia and East Africa. The effects of the tsunami on skin conditions have not been evaluated. OBJECTIVE: To determine the influence of the tsunami on skin conditions by evaluating the skin problems of patients presenting at hospitals after the tsunami. METHODS: Between 5 and 25 January 2005, two dermatologists evaluated patients who complained of skin problems at an outpatient clinic and emergency room of a general hospital in Banda Aceh, Aceh Province, Indonesia. RESULTS: The total number of patients that presented during the study period was 235 (131 males and 104 females), and they had a total of 265 skin problems. In terms of age distribution, most subjects were in their fourth decade (23.0%), followed by the third (22.6%) and fifth decade (16.6%). The most prevalent skin problems were infections-infestations (32.5%), followed by eczemas (29.8%) and traumatic skin disorders (29.4%). In males, traumatic skin disorders were most common. The great majority of infection-infestation cases involved superficial fungal infections. Contact dermatitis accounted for three-quarters of eczema cases, and mainly involved the arms (40.0%) and legs (27.1%). The majority of traumatic skin disorders were lacerations, punctures and penetrations, and the feet (44.7%) and hands (18.8%) were most frequently affected. CONCLUSIONS: Unhygienic conditions, exposure to a hazardous environment and contact with various objects during and after the tsunami probably increased the prevalence of infections-infestations, traumatic skin disorders and contact dermatitis. To prevent these problems and associated secondary bacterial infections, health-related education and early medical management are required.     

Manganese and arteriosclerosis

The relations between manganese and atherosclerosis were examined on rabbits with experimental atherosclerosis, on patients with atherosclerosis and on workers exposed to manganese. Here a favourable influence of manganese was shown which effected a decrease of the cholesterol content of serum, liver and aorta and inhibited the entry of lipids into the aorta. The influence of the manganese on various enzymes as well as a manganese-copper interaction are discussed as possible causes.     

H2-receptor antagonists and the incidence of gastroduodenal ulcer perforation and hemorrhage. An epidemiological study

The only curative treatment to proximal bile duct cancers with involvement of both hepatic ducts is liver transplantation. A curative resection with wide lateral clearance is limited due to the neighbourhood of vital anatomic structures in the liver hilum. The majority of patients with bile duct cancers is over 60 years of age and due to concomitant disease, they do not fulfill the requirements for liver transplantation. Our treatment strategy in adequate cases is palliative tumor resection and reconstruction of bile passage by sutureless biliodigestive anastomosis as proposed by Rodney Smith. We treated 11 patients with this method, in 5 patients an additive combined radiotherapy by percutaneous radiation and intraluminal after-loading therapy was performed. Our results indicate that this strategy leads to effective palliation in cases provided that only microscopic residual tumor is left in situ (R1-resection). Our observed survival times compare favorably to survival times after liver transplantation (average survival time 11.5 months median survival time 10 months).     

Experimental studies on the action of extracts of herba recens Echinaceae purpureae on skin flaps

In animal experiments the effects of Echinacin, a sap made from Herba recens Echinaceae purpureae, on the rate of necrosis of skin flaps were studied in comparison with NaCl and pentoxifylline. The fluoresceine test was used as an indicator of peripheral circulation. The noncirculated area of the skin flap was significantly smaller in Herba Echinaceae treated animals than in control animals (p less than 0.01). On the day of the operation the size of the noncirculated flap area was only 56.0%, whereas it was 77.8% in the NaCl group and 67.4% in the pentoxifylline group. Until the 5th postoperative day the ratios changed to 47.4% (Herba Echinaceae), 76.6% (NaCl) and 50.4% (pentoxifylline). While more than two thirds of the skin flap area were to become necrotic in the NaCl group, less than half of the skin flap was so in the Herba Echinaceae group. Thus Herba Echinaceae significantly decreased the rate of necrosis of skin flaps in animal experiments.     

Odd-numbered long-chain fatty acids in erythrocyte phospholipids as long-term follow-up parameter in propionic acidemia.

Odd-numbered long-chain fatty acids (OLCFAs) increase in total erythrocyte lipids or plasma in patients with propionic acidemia and have been proposed as a useful parameter of metabolic control. However, up to now no parameter for long-term metabolic control has been available for this disorder. In contrast to previous investigations, we investigated OLCFAs with particular reference to differences for two phospholipid fractions of erythrocyte lipids. The phosphatidylethanolamine (PE) fraction of erythrocyte lipids has a slow turnover rate and might reflect the metabolic propionyl-CoA burden over a period of some weeks. Distinct increases in OLCFA of up to 200% in the phosphatidylcholine fraction were observed after episodes of metabolic decompensation and maximum OLCFA levels were found 3 weeks after the onset of a crisis. As a sign of poor metabolic control, OLCFA levels in PE steadily increased after recurrent episodes of decompensation, but not in clinically stable patients. However, in one patient with clinically good metabolic control, OLCFAs continually increased after the second year of life for an as yet unknown reason. In conclusion, data from this study indicate the usefulness of OLCFA analysis in the PE fraction of erythrocyte lipids, in particular with regard to the need for such a parameter for evidence-based improvement of management strategies in propionic acidemia.
