I was originally going to buy a Cortex straightener but then decided on a Chi, good choice or no?

---

Originally going to buy Cortex straightener, the zebra print one, and then bought a Chi Chi-tah. Did I make the right decision? I heard Cortexes have a tendency to break and can be a real rip-off but then I heard something that Chi's are known to catch on fire and can also be more damaging to the hair.

Anyone have personal experience with both?
I was able to try the cortex straightener in the mall recently and i loved it, i been researching like crazy between the chi and the cortex. So I say you prob should have purchased a cortex: I been reading almost every where that chi irons break easily and for their price they shouldn't.  (+ info)

What is the neo-cortex and why is it important when it comes to abortions?

---

Some information I've read says that the formation of the neo-cortex should be used to determine up to what point in development an abortion should or should not be performed.
Development of the fetal neocortex begins at 8 weeks gestation, and by 20 weeks each cortex has a full complement of 109 neurons. The dendritic processes of the cortical neurons undergo profuse arborizations and develop synaptic targets for the incoming thalamocortical fibers and intracortical connections. The timing of the thalamocortical connection is of crucial importance for cortical perception, since most sensory pathways to the neocortex have synapses in the thalamus. Studies of primate and human fetuses have shown that afferent neurons in the thalamus produce axons that arrive in the cerebrum before mid-gestation. These fibers then "wait" just below the neocortex until migration and dendritic arborization of cortical neurons are complete and finally establish synaptic connections between 20 and 24 weeks of gestation.  (+ info)

Does a torn rotator resemble avascular necrosis when looking at the results of an MRI?

---

Why would one doc say it's a torn rotator and the other say it's avascular necrosis when they're looking at the same films and doing the same tests?
A couple of thoughts...I'm not a radiologist, but my first question would be - were both of these docs radiologists? Because a torn rotator involves soft tissue and avascular necrosis involves bony tissue, I would think they could be differentiated on the MRI as long as you had a good quality MRI done on an up-to-date machine and read by a radiologist. I'd get a third opinion that includes comments on the quality of the scan. These 2 problems are treated so differently, you really need to find out which one it is.  (+ info)

How can I find a kidney specialist that will work with me on payments?

---

I have been to doctor after doctor, hospitals and clinics about my kidney. I stay with kidney stones, urinary tract infections and and kidney infections. They all tell me the same thing "see a kidney specialist" I cant afford to just take 100.00 to 200.00 all at one time out of my pay check, so are there specialist out there that will let you make payments?
Do you have any insurance at all? Try checking with your local health clinic its possible to get some help with the payments through the state,or look on the net @ your states options they may have the income guidlines alreay posted.
Or call around or get referral from PCP and ask if theres anyway they will work with you.  (+ info)

What are the symptoms of kidney failure?

---

I have a kidney transplant for 26 yrs. so far but my blood pressure has been a little bit up like 110/90 but it's always been this way. My cholesterol has been going up but my doctor say it's because I've been taking Prednizone all my life. Out of curiosity, I just want to know what is the most that a kidney can last. I have my mom's kidney because I have no sibblings.
According to statistics, by 10 to 15 years, about 50% of transplanted kidneys are still functional. Rates improve if the kidney comes from a living relative.
The signs and symptoms of kidney failure vary, depending on whether the failure is acute or chronic.
Acute kidney failure occurs when your kidneys suddenly stop filtering waste products from your blood. The signs and symptoms may include:
Fluid retention
Bleeding, often in your stomach or intestines
Confusion
Seizures
Coma
Chronic kidney failure
According to the National Kidney Foundation, almost 20 million adult Americans have chronic kidney disease and another 20 million are at risk of developing it. Over time, chronic kidney failure can lead to congestive heart failure, weak bones, stomach ulcers and damage to the central nervous system. Unfortunately, signs and symptoms often don't appear until irreversible damage has occurred. They include:
High blood pressure
Unexplained weight loss
Anemia
Nausea or vomiting
Malaise or fatigue
Headaches that seem unrelated to any other cause
Decreased urine output
Decreased mental sharpness
Muscle twitches and cramps
Bleeding in the intestinal tract
Yellowish-brown cast to the skin
Persistent itching
Sleep disorders
End-stage renal disease  (+ info)

Why does steroids cause avascular necrosis of the femural head?

---

This comes in context of Hodgkin's Lymphoma where prednisolone is give as a drug for it and one of the complication is avascular necrosis of the femural head.
Good question. (femoral)
Here's an excellent analysis from emedicine/WebMD updated recently in August 2008. Various mechanisms are discussed if you read this article, but the bottom line is that no one really knows for sure.

What is the prognosis of these kidney stones?

---

Hi everyone,

My Mum's 57 and has a kidney stone. She has had it for about 25 years, it hasn't grown and she hasn't passed it either. She sees her doctor each year, and her kidney function hasn't decreased.

However, she only has 1 functioning kidney (that's the kidney with the stone) and the other one only has 20% functioning because she had a congenital kidney condition.

Is her kidney stone likely to decrease the length of her life?

Honest answers please.

Thank you so much.

Is there a link between kidney problems and developing astigmatism in 4 year old?

---

My 4 year old daughter passed 2 eye exams in previous year and then failed her 4 year screening and went to the eye doc the next day.

He measured her eyes with a machine and said that she has astigmatism on her eyes.

She has kidney damage to her "good" kidney and a duplex kidney on the other side.

Is there a link between kidney problems and developing astigmatism in 4 year old?
BTW she is having her yearly kidney scan today, keep her in your prayers please.
I can think of virtually no connection.

Young children's eyes can change rapidly anyway,
astigmatism is only a variant on short or long-sight,
and children's eye-testing at that age can be somewhat variable of itself.

If the refraction is a significant shift, outside unlikely possibilities will be considered by any competent examiner:
developing cataract...? Very unlikely, but not unheard-of, especially if there are other genetic or congenital anomalies present.
Keratoconus? Again, a rare inherited condition.

In neither case is there a need to rush to diagnosis, this can just be "watched", just as a simple changing Rx will be.

Best wishes,
Optometrist, retired.

Is there a correlation between kidney function and body odor?

---

I need to see a neurologist. The doctor is concerned about my kidneys. My family is concerned about my strong odor. Is there a connection between kidney function and body odor? Please let me know. Thank you.
Dominee does depression play a part in this?
yes - when your kidneys do not function properly waste products and excess fluid then build up inside the body and can cause a foul body odor and breath that smells like urine.

You would usually have symptoms like persistent fatigue or shortness of breath; loss of appetite; increasingly higher blood pressure; pale skin; excessively dry, persistently itchy skin.

#1 & 2 causes for bad body odor are Diet and hormone level. **ALCOHOL consumption is included in diet...as well as all other beverages like soda and sugary juices.

If you have no other real symptoms ... i would put money on diet.  (+ info)
