B&W twins – One in a million

Kylie Hodgson gave birth to twin daughters by caesarean section, then she realised a difference between them.

This amazing conception happened after two eggs were fertilised at the same time in the womb.

The odds against of a mixed race couple having twins of dramatically different colour are a million to one.

Skin colour is believed to be determined by up to seven different genes working together. For a mixed-race couple, the odds of either of these scenarios is around 100 to one. But both scenarios can occur at the same time if the woman conceives non-identical twins, another 100 to one chance.

This involves two eggs being fertilised by two sperm at the same time, which also has odds of around 100 to one.

If a sperm containing all-white genes fuses with a similar egg and a sperm coding for purely black skin fuses with a similar egg, two babies of dramatically different colours will be born.

The odds of this happening are 100 x 100 x 100 – a million to one.

Massive postincisional hernia of the abdominal wall

This is the case of a 69 years old diabetic female patient with history of subtotal colectomy for advanced colon cancer a year ago.

She had a surgical complication of the abdominal wall called postincisional hernia and came to surgical consult because of this giant ventral hernia. This is one of the largest hernias I’ve ever seen.

A laparoscopic repair of the defect was made with Prolene mesh (2 sheets of 12″ x 12″) sutured to the fascia and now she is doing very well.

OsseoNews – Dental Implants

This is a paid review

Dental implants are designed for teeth that are lost or damaged beyond repair. Modern dental implants can provide a permanent replacement that maintain the look, feel, and function of natural teeth.

Do you know what dental implants are, what are their benefits, who is a candidate, how much a dental implant cost and what kind of procedures are performed? I didn’t knew anything about this until I read the OsseoNews website.

Did you know that dental implants inserted in a proper manner could succeed in natural bone as 95%?

If you are a patient, you could find info regarding dental implants on the site.

I have a lot of dentists visiting my site and for those who want to share their knowledge in dental implants or want others opinion, you can upload your cases just subscribing to the site.

OsseoNews is a great discussion community for dental professionals. You could share or find information of particular dental implant topics like:

Bizarre dermatologic lesions

Via Boingboing
Link WFMU’s

A missionary in Eastern Europe recently reported an extremely rare (condylomatosis) skin condition. This disease is called Lewandowsky-Lutz dysplasia. This missionary wrote:

I found this man, and other than his hands and feet, he looked and seemed in good health. As best as I could gather these growths began when he was 14 years old, and began in the area of his wrists. The skin on his wrists and the back of his hands resembles that of a hedgehog – hundreds of spike like growths. The problem is much more severe on his palms and fingers where the growths resemble very much that of nails infected with a fungus. The growths have that same texture, smell and feel. I cut a number of the largest growths off, most of witch did not bleed. Some of the smaller growths did bleed a small amount and he seemed much more sensitive to the cutting of the smaller growths.

It has grown slowly but steadily but has not spread to other parts of his body, just a bit below his knees on his legs. He has other skin growth (many would be skin tags) on his face, and some moles on his chest. The growths are not as bad on his feet but I was told that more than 10 years ago many we cauterized off his feet, and they did not return. I think with repeated soaking and cutting most could be removed but other parts will I think need to be burned away in some form.”

He has 15 skin tags on his face, and a wart in one ear.

Another firecracker explotion

Previous proof of firecrackers injuries here.

For those who don’t believe in injuries caused by firecrackers explotion. I just saw a patient in the E.R. of my hospital who came because he was walking near a park and some kids were buying firecrakers in the street. A kid ignited a firecracker and it exploted next to the box that containded the firecrackers. The patient was 10 ft away from the box and the explotion cause this right side injuries.






As you can see, the injuries are projectile-like injuries and he didn’t burn. A witness told me that lots of wood sticks and asphalt stones flew far away.

A Plastic Surgeon and I repaired the injuries and noted an irregular perforation at the right cheek, that penetrated towards the floor of the orbit and produced a coronoid apophysis fracture.

After the reparation:


I strongly recommend never play with firecrackers.
