Cancer Risk Higher For Hairstylists or Barbers

A report coming from the International Agency for Research on Cancer which was recently published in the Lancet Oncology reported that working as a hairstylist or barber does have occupational hazards. A small but consistent risk for bladder cancer was noted in male hairdressers and barbers. As there were no reliable data on duration and periods of exposure the data are considered to be limited evidence of a cancer risk. Some carcinogenic substances have been present in modern hair dyes.

These particular colorants were discontinued in the 1970’s after positive cancer tests in mice and rats were seen. The researchers also examined the personal use of hair dyes, but could not show an adequate evidence that hair dyes would be cancerogenic. As a result they also could not definitely judge that the dyes carried a cancer risk.

Other chemicals that like hair dyes belong into the group of aromatic amines were assessed by the researchers.

Ortho-toluidine which is used in the production of dyes, pigments and rubber chemicals is now classified as a carcinogenic substance to humans, as is the chemical called MOCA , which stands for 4,4-methylene bis (2-chloroaniline) and is used as a curing substance in the plastics industry.

Cancer Risk Higher For Hairstylists or Barbers

The consumer needs to be aware that the cosmetics industry that produces shampoos and hair conditioners and companies that produce hair dye for home use often use parabens and other mildly carcinogenic substances as a preservative that will be additive to the cancer producing effect of the hair dyes used in saloons.

Tree Pollen Connected With Mood Disorders

By Ray Schilling | Allergies, Asthma, Mental Health

Seasonal affective disorder (SAD) does have its grip on people who react to a lack of sunlight in the winter month. As a result depression in the winter season is not uncommon. Some people just report it as feeling “down” and “tired” or report a lack of energy. Despite all the reports about SA, epidemiological studies have shown that the rate of depression is not the highest in dreary months like January or February but it spikes in the months of April and June. Dr.Teodor Postolache, a psychiatrist at the University of Maryland made a recent presentation at a meeting of the American Acadamy of Allergy, Asthma and Immunolgy delving into the reason for this finding. He compared the exposure of tree pollen which triggers a cytokine release to a tsunami.Virtually no outdoor allergens are present in the winter months, but with the release of tree pollen people who are vulnerable to allergies are exposed to massive amounts of allergens. The released cytokines may affect brain function and behaviour, resulting ultimately in changed cortisol levels and an altered serotonin metabolism. After breathing the cytokines are already released in the nose and they can continue their action in the prefrontal brain area where the centers for mood, anxiety and impulsivity are located. Dr. Postolache and his colleagues confirmed that individuals with a history of allergy and asthma had a 2.5 fold of suicide compared to controls and those with allergic rhinitis had a 1.7 fold higher risk.

Tree Pollen Connected With Mood Disorders

For the first time it could also be demonstrated that cytokine levels in suicide victims were significantly elevated in the orbitofrontal cortex, the brain area that affects mood. Intranasal corticosteroids in the form of nosedrops can bring significant relief to allergy sufferers, and Dr. Postolache and his team will examine the benefits of intranasal corticosteroids closer in a clinical study. Whereas systemic corticosteroids have shown a negative impact on mood disorders and depression, the local application of a nasal spray or drops is geared to abolish the pathways from the nose to the brain for the inflammatory cytokines.

Early Use of Immunosuppressive Drugs for Early Crohn’s Patients

By Ray Schilling | Arthritis, Gastrointestinal Disease, Pain

So far the strategy of treating patients, who were newly diagnosed with Crohn’s disease, was the use of corticosteroids to control abdominal pain and bloody diarrhea. The conventional mode of treatment consisted of a “step-up” treatment: after corticosteroids the use of immunosuppressants and finally antibody treatment would follow to curb the inflammatory response. International data which were published in the Lancet (February 23 issue) points to a safer and more effective treatment protocol. It consists of a “top-down” approach rather than of the conventional “step-up” approach. Patients receive immunosuppression early in the form of azathioprine and also the antibody infliximab, known as Remicade. Another study examined patients who were on maintenance therapy with adalimumab (Humira). They experienced sustained improvements in the symptoms that are associated with Crohn’s disease. After 4 weeks of induction therapy with the medication patients with mild and severe depression had improved to such an extent that they returned to the normal range. They were also assessed regarding fatigue and after treatment they showed a significant improvement in their daily functioning. The two treatment protocols were compared in a trial involving 129 patients with Crohn’s disease who had no previous treatment. At the end of the trial the researcher found that 65% of the group that had received the “top-down” treatment was symptom free after 26 weeks of treatment. Contrary to this only 36% of the “step-up” patients went into remission during the same time.

Crohn’s before and after immunosuppressive drugs

When the patients were examined after 1 year, 62% of the “top-down” group was still symptom free, but only 42% of the “step-up” group had no symptoms. Dr. Brian Feagan of the University of Western Ontario coordinated this trial involving international sites in Belgium, Holland and Germany. He points out that the newly diagnosed Crohn’s disease patient that has the worst prognostic signs will benefit from this form of treatment. The top-down modality also is safer, as it protects the patient from high exposure to steroids. Similar results were demonstrated in patients with rheumatoid arthritis. The results of these trials and Dr. Feagan’s research suggest that the top-down treatment option could also give the best chance to patients with other chronic autoimmune diseases such as ulcerative colitis.

Short Daily Exercise Helps Chronic Pain Patients

By Ray Schilling | Arthritis, Fitness, Health, Pain

Chronic pain can be an affliction that turns normal living and functioning upside down. Quality of life will be negatively affected, and often depression and anxiety are resulting mental problems. Effective pain relief is crucial, but often there are undesirable side effects to pain medication, and the patient will explore other avenues that bring a measure of relief. Amy Burleson, Psy.D. of the Cleveland Clinic’s chronic pain rehabilitation program found that chronic pain patients were physically deconditioned due to chronic pain and a chronic lack of physical activity. Depression and other mood disorder also were very common. A 10 minute exercise program was added to the treatment of a group of 28 patients who suffered of various chronic pains: back pain, fibromyalgia, neuropathy and migraines. Patients started a simple routine of walking on a treadmill, starting with a low speed of 1 mile per hour and increasing the speed every few minutes, till they walked at a speed of 3 miles per hour, a speed which was manageable for all patients. After 3 weeks patients found that their physical endurance had increased. They also experienced less depression and anxiety. Even more remarkable was the fact that the patients’ pain perception had diminished.

Short Daily Exercise Helps Chronic Pain Patients

Likert scale scores which were used in the assessment of pain perception showed a drop from 7.32 in the beginning of the program to 2.75 at 3 weeks. It is obvious that even mild exercise has benefits for patients with chronic pain: the overall well being receives a noticeable boost through an approach that has no pharmacological impact, no side effects and has no high cost of health care.

High-intensity focused ultrasound (HIFU) Treatment For Prostate Cancer

By Ray Schilling | Cancer

High-intensity focused ultrasound, also known as HIFU is a treatment that prostate cancer patients are seeking out. The treatment technique is minimally invasive, has low risks of impotence and urinary incontinence and can be done on an outpatient basis. It is a two to three hour procedure which can be done with some mild sedation and spinal anaesthesia, and generally men can resume their normal lives immediately after surgery with the knowledge of being cancer-free. Dr.Ian Brown, the medical president of the Niagara HIFU clinic in Niagara Falls, Ontario likens the technique to the effect of a magnifying glass that focuses sunrays on a leaf and burns it. Except there is no sunlight, but a pulse of high-energy ultrasonic waves focused onto a specific area of the prostate. Temperatures reach approximately 90 °C (= 194 °F), until the cancer cells are dead. The transducer is equipped with ultrasonic imaging, so the treating physician can see the entire prostate gland on a monitor, and as a result surrounding nerve structures that are responsible for erectile function are not damaged. There is some inconvenience for the patient after the surgery. He has to wear a catheter for two to three weeks until he can urinate on his own. Like any prostate cancer treatment, HIFU also has potential side effects like retrograde ejaculation or urethral fistula.

High-intensity focused ultrasound (HIFU) Treatment For Prostate Cancer

Reports state that these side effects are minimalized with HIFU, but they are not eliminated. This treatment is not suitable for every patient. Patients with early stage prostate cancers are suitable candidates. HIFU is not available in the US at present, but has been approved by Health Canada in 2004 based on European data. It is not covered by health insurance, and at $20,000 this new costly option is not affordable for everybody.

Comment: Here is an update regarding FDA approval in the US. According to the FDA panel there is not enough solid data to confirm effectiveness or safety, so it was not approved in 2014.

High Blood Pressure Decreases Cognitive Function

By Ray Schilling | Heart Disease, High Blood Pressure, Prevention, Stroke

It is known that high blood pressure that is left untreated gives rise to a host of health problems, some of which are heart attacks and strokes. It is not surprising to Dr. Jose Luchsinger of Columbia University Medical Center in New York that high blood pressure (hypertension) can be related to all kinds of cognitive impairment, which is connected to vascular damage in the brain. A cohort study which was published in the December issue of Archives of Neurology included 918 subjects age 65 or older with no history of mild cognitive impairment (MCI) or dementia at baseline. All participants underwent neurophysical and medical testing every 1 ½ years for more than 4 ½ years. The majority of the individuals had high blood pressure. During the course of the study 334 of the participants developed MCI. 174 cases had impairment in domains such as language and executive function or visual-spatial elements were impaired. 160 individuals had amnestic MCI (affecting memory), which is thought to have the strongest link to Alzheimer’s disease.

High Blood Pressure Decreases Cognitive Function

The study showed that hypertension played a significant role in the higher risk of developing any form of cognitive impairment. Detection of hypertension and proper treatment will not only protect against strokes, but certainly also extend its benefits to cognitive function.

Eat Your Veggies To Protect Your Eyes

By Ray Schilling | Eye Diseases, Nutrition, Vitamins and supplements

A study at Brigham and Women’s Hospital in Boston has shown that nutrition impacts eye health. Over a stretch of 10 years Dr. William Christen followed a group of 35,551 health professionals age 45 and older. They provided him with detailed information about their dietary habits and vitamin supplements-they were permitted to take multivitamin but were requested not to take vitamin A, vitamin E or beta-carotene. None of them had cataracts in the beginning of the study, but 2,031 did develop cataracts during the follow up period. Dr. Christen and his team analyzed the data and found that those individuals who were the highest consumers of carotenoids- individuals with an intake of 6,617 mcg of lutein and zeaxanthin- were 18% less likely to develop cataracts than those who consumed only 1,177 mcg per day. Also, the group that consumed higher amounts of vitamin E (intakes of about 262.4 mg per day) was 14% less likely to develop cataracts. Lutein is a substance that is found in high concentration in eye tissue. It is readily available in many foods, such as green and yellow vegetables, yellow-fleshed fruit and in egg yolks.

Eat Your Veggies To Protect Your Eyes

New research from the National eye Institute in Baltimore has also confirmed the benefits of carotenoids for healthy eyes. Lutein and zeaxanthin offer protection against age-related macular degeneration. There is no need to shop for supplements. Just bring on the green vegetables: broccoli, brussels sprouts, kale, collard greens, and spinach. Add some corn, the spice saffron and some eggs, and enjoy the taste and the health benefits.

H. Pylori Can Be The Culprit For Indigestion

By Ray Schilling | Abdominal Pain, Gastrointestinal Disease, Infectious Disease

Indigestion, heart burn, bloating and stomach discomfort are common problems. Often the reason is simple. Too much food and drink at a party, a plateful of deep fried Buffalo wings or a midnight order of double-pepperoni pizza will contribute to stomach upset and a bad night’s sleep. A few over the counter antacids will come to the rescue. If indigestion is a faithful but miserable daily companion, the excuse of “just having a sensitive stomach” becomes a form of denial and a dangerous form of self diagnosis. Something is wrong, and it is time to seek medical attention instead of over the counter meds. The first line of defense will be prescription drugs called “proton pump inhibitors” (PPI). They are designed to eradicate excessive acid production in the stomach. If symptoms are more severe, e.g. weight loss, a gastroscopy will be necessary. Even though the prevalence of a stomach infection with Helicobacter pylori (H.pylori) is declining, about 30% of patients with chronic stomach upsets test positive for an infection with these bacteria. This can cause recurrent stomach pains. In this case it becomes necessary to treat this with a combination of PPI’s and antibiotic medication. Eradication of H.pylori can mean a cure from a stomach ulcer. It also reduces the risk of developing gastric adenocarcinoma, a form of stomach cancer that could have developed out of an untreated gastric ulcer. Just because a person has heartburn does not mean that the condition is due to gastro-esophageal reflux of stomach acid. If after treatment with a PPI the problems of indigestion, heartburn, bloating or stomach aches reoccur, lab tests can give more information. According to a prospective trial conducted by Dr. Delaney and others the H.pylori serology (a blood test) is unreliable, but other H.pylori tests like urea breath test or stool antigen are reliable tests to establish whether a stomach infection with H.pylori is present or not.

H. Pylori Can Be The Culprit For Indigestion

If the bacterium is present, its eradication with antibiotic therapy will stop the stomach problems in a high percentage of cases with one treatment protocol. What was surprising was that after one year the treatment result of the treatment group with PPI/antibiotic combination was as successful as the control group that was treated with PPI’s alone. It was concluded that in the more severe cases with weight loss, vomiting, or overt bleeding an upper gastrointestinal endoscopy should be performed where a direct H.pylori test from samples is also done. However, in the vast majority of cases with minor symptoms can be treated safely by the general practitioner with PPI’s and follow-up examinations in subsequent visits. Treatment failures can then be referred to a gastroenterologist, if necessary.

Early Breast Cancer Diagnosis With PET/CT Scan Combination

By Ray Schilling | Cancer, Women’s Diseases

Breast cancer remains a disease that can strike women in any age group. Despite the immense amount of ongoing research and new treatment modalities, the disease presents puzzles to researchers and treating physicians and enormous challenges to patients. Early diagnosis, accurate staging of the disease and prompt treatment remain the most important points. Breast self examinations on a regular basis are just one aspect. Mammography screening can pick up the disease earlier, and a biopsy of any suspicious area can tell more about the type of cells that cause it. A particularly aggressive type is inflammatory breast cancer. It is not characterized by a suspicious lump. The only symptom is diffuse redness and swelling in the breast of the patient.

This type of cancer can metastasize within six months. It accounts for 1 to 5% of all breast cancers in North America and has a five year survival rate of 25 to 50% of the patients. A team of researchers from the University of Texas M.D.Anderson Cancer Center in Houston led by Dr. Selin Carkaci examined a combination approach of high tech tests for early diagnosis and treatment. Dr. Carkaci pointed out that breast cancer is not a localized disease, but one that is systemic involving the entire body. Based on this knowledge 41 patients with the highly aggressive form of inflammatory breast cancer were examined with a combination PET/CT whole body scan. It was possible to identify cancer in patients’ lymph nodes with 98% accuracy. Early metastasis could be found in 49 % of patients.

Early Breast Cancer Diagnosis With PET, CT Scan Combination

Nodule in lung. A: PET scan . B : CT scan. C : PET, CT scan combo.

PET/CT scan combinations detect cancer in its earliest stages, when changes are happening at the cellular level. Other tests like mammograms, ultrasound and MRI scans can only identify disease when there is destruction of the normal anatomy. The accurate depiction of the cancer within the body is important for an effective treatment plan. PET/CT combination scans are used in cancer diagnosis for a variety of tumors where distant metastases are expected (the image above shows a nodule in one of the lungs). It is especially significant for inflammatory breast cancer patients, where it offers a promise for earlier diagnosis resulting in more effective treatment plans.

The Culprits For Periodontal Disease

By Ray Schilling | Dentistry, Heart Disease, Men's Health, Substance abuse, Women’s Diseases

When people think of hazards to dental health, the first thought will be about tooth decay, lack of brushing and flossing and eating candies and other sugar-laden foods. Periodontal disease is often neglected, and yet it is just as threatening to teeth and gums. Destructive periodontal disease will lead to loss of the supporting tissues of the teeth and as a result, there will be loose or shifting teeth and ultimately tooth loss. Generally these findings were seen in older population groups. It was thought that the disease would rarely occur in patients younger than 35 years of age and the theory was that dental plaque was the likely cause. Lifestyle choices were not thought to play a large role. Recent findings told a different story. A cohort study consisting of 903 participants examined self-reported tobacco and marijuana smoking and dental examinations were also done. The authors of the study found that tobacco smoking as well as cannabis (marijuana) smoking was linked with a higher incidence of destructive periodontal disease before the age of 32 years.

The Culprits For Periodontal Disease

In comparison to this dental plaque was not contributing to a higher incidence of periodontal disease in this younger age group. Another risk for destructive periodontal disease in the youngest age group (as young as 12 to 18 years of age) was impaired glucose intolerance (a condition leading to diabetes). Due to those findings it is obvious that brushing and flossing are not the only weapons against periodontal disease. Healthy eating habits and cessation of smoking are equally important for dental health. This is particularly important as heart disease, which is also an inflammatory condition is closely linked to inflammatory disease of the gums and you likely have heard that heart attacks can be prevented by brushing and flossing teeth.
