The ‘hockey-stick’ palmar crease is an unusual variant of the distal palmar crease – in palmistry a.k.a. the ‘heart line’. The typical characteristic concerns the widening of the crease combined with a termination between the index- and middle finger.
The ‘hockey-stick’ crease is relatively common in CHARGE, and in fetal alcohol syndrome (FAS).
THE HAND IN CHARGE SYNDROME:
A typical CHARGE hand displays a combination of the following characteristics: square hand, short fingers, finger-like thumb, and hockey-stick palmar crease.
THE HAND IN FETAL ALCOHOL SYNDROME:
A typical FAS hand displays a combination of the following characteristics: small thumb, short fingers, clinodactyly (curved 5th finger), camptodactyly, broad palm, and hockey-stick palmar crease.

New study reports: hand gels are misleading, only killed 60 per cent of germs at best.
Last year, when swine flu hit, sales of some products rocketed by 70 per cent. Yet do hand gels really help? A study carried out in December 2009 by Ottawa University found that some brands that claimed to kill ’99 per cent’ of germs did not – at the very best they killed 60 per cent, and at worst just 46 per cent.
A dailymail report describes:
“The Medicines and Healthcare Products Regulatory Agency says it has had to investigate numerous hand-cleaning products for making claims that they can kill specific viruses such as swine flu or MRSA. They are not allowed to make these claims, because it gives the impression they have some medical effect. Gels can only really help kill everyday germs, such as those that cause the common cold. Yet few people realise that the hands have to be clean in order for many hand gels to work.
‘Like many cleaning agents, most hand gels will be less effective in the presence of protein matter, such as food, mud, faecal matter or blood,’ says Dr Ron Cutler, a microbiologist from Queen Mary, University of London. ‘You really need to wash off all visible signs of dirt before they will be totally effective.’ Many hand gels contain alcohol, which kills germs by attacking their outer membrane. For maximum benefit, a hand gel should contain at least 62 per cent alcohol – but no more than 80 per cent. This is because the gel should contain some water, as once the outer membrane of the bacteria or virus has been penetrated it is water that kills it.
But new research suggests that hands gels won’t protect against gastroenteritis or viral stomach bugs such as norovirus. Furthermore, a recent study by the Agri-Food and Biosciences Institute, Belfast, found that even Spirigel, the alcohol-based gel used in NHS hospitals, stops working within seconds of use. A non-alcohol gel offered much longer protection, killing viruses for up to 24 hours after it was applied.
Should we abandon alcohol hand gels? Non-alcohol gels work in a variety of ways. Byotrol, the gel used in this study, contains mainly water, but the gel forms an invisible layer that stays on the hands and literally pulls bacteria and viruses apart. Some others, such as No Germs, use chemical antibacterial agents or even essential oils. ‘When alcohol hand gels were first introduced years ago, it was so much better than anything else,’ says microbiologist Stephen Falder, who helped develop Byotrol. ‘But if you were going to start designing a hand gel now from scratch, you would abandon alcohol.’
He adds: ‘Alcohol stops working almost as soon as it’s dry, and does not give you residual protection.’ other experts disagree and say that while the effects of non-alcohol hand gels may last longer, alcohol is better at killing germs.
Professor John oxford, a virus expert from St Barts and Royal london Hospital, says he would always prefer an alcohol-based gel. ‘Yes, it might not work against things like norovirus, but norovirus is a very difficult bug to get rid of and nonalcohol gels won’t work against it either – little will. ‘The alcohol ones do work and certainly work against things like swine flu.’
Mr Cutler backs him up. ‘If my hands were dirty, I would wash them first with soap and water, using lots of agitation. ‘This cleans off all visible dirt. I would then apply an alcohol hand gel to get rid of any residual bacteria. ‘There are non-alcohol based products, some for example contain citrus oils, but I am not sure how strong an alternative these are. Washing your hands is the best option. ‘This should definitely be done after you go to the loo, after changing a nappy, after you sneeze, before you eat, before preparing food and after handling raw foods such as meat.'”
“The gold standard of hand washing is using hot running water and soap.”
“‘You need to wash both the palms and the finger tips and around rings of the fingers, as bacteria can lodge there,’ says Dr Anthony Hilton, a reader in microbiology from Aston University. ‘Then you should dry with a paper towel or hand drier. However if this is not available, then alcohol-based hand gels can be a very good substitute.'”
So, the essential is: do not consider hand gel sanitizers as a ‘safe’ alternative for hand washing!!!

|About H1N1 Prevention & hand hygiene!
Alcohol-based hand sanitizers — which don’t require water — are an excellent alternative to hand washing, when soap and water aren’t available.
A hand sanitizer is actually MORE effective than soap and water in killing bacteria and viruses that cause disease! For, organisms cannot develop resistance to alcohol, and commercially prepared hand sanitizers contain ingredients that help prevent skin dryness.
|But one should be aware that not all hand sanitizers are created with likewise substances. Some “waterless” hand sanitizers do not contain any alcohol. In general one should use only the alcohol-based products. The American CDC (Centers for Disease Control and Prevention) recommends choosing products that contain at least 60 percent alcohol.
This is how to use an alcohol-based hand sanitizer:
• 1 – Apply 1/2 teaspoon of the product to the palm of your hand.
NOTICE:If your hands are visibly dirty, however, wash with soap and water, if available, rather than a sanitizer!!!

In May 2009 the World Health Organization (WHO) has presented new guidelines for hand hygiene and handwashing. The guidelines were targeted at hospital administrators, public health officials, and healthcare workers (HCWs).
The new guidlines are designed to be used in any setting in which healthcare is delivered either to a patient or to a specific group, including all settings where healthcare is permanently or occasionally performed. Details are presented for the following: hand hygiene indications, hand hygiene techniques, selecting hand hygiene agents, recommendations for skin care + glove use, and surgical hand preperation.
A few quotes from the new WHO guidlines:
“• When washing hands, wet hands with water and apply enough soap to cover all surfaces; rinse hands with water and dry thoroughly with a single-use towel. Whenever possible, use clean, running water. Avoid hot water, which may increase the risk for dermatitis.
• Liquid, bar, leaf, or powdered soap is acceptable; bars should be small and placed in racks that allow drainage.
• When using alcohol based handrub, rub a palmful of alcohol-based handrub over all hand surfaces until dry.
• Soap and alcohol-based handrub should not be used together.”

Recently Q-Based Healthcare, a producer of non-alcohol-based hand sanitizers, warned: ‘alcoholic hand sanitizers increase risk of swine flu exposure’. Why can many hand sanitizers (such as the popular Dettol) cause more health problems than they prevent?
Recent news reports indicate that retail stores are seeing a dangerous reduction in the inventory levels of hand sanitizer. As more people become concerned and flock to the stores to stock up on alcohol-based hand sanitizers, a bigger crisis is being created.
Did you know that alcohol-based sanitizers work by stripping away residue from the hands, and unfortunately that includes the natural oils produced by our body? Most hand wipes and liquid hand sanitizers are alcohol based (or petroleum). The problem with these products is that Alcohol dries the skin causing cracks – creating an opening which provides a direct pathway for disease to the human bloodstream. That’s why the use of hand sanitizers may actually worsen the current major global health threat: the mexican flu (a.k.a. the swine flu)!
When a hand sanitizer includes an alcohol or a petroleum by-product, that hand wash also presents a real possibility for toxic exposure, whether it includes organic ingredients or not!
