Chiropractic Adjustments Change Skin Temperature
Chiropractic adjustments may trigger changes in paraspinal skin temperature, according to an investigation of 20 individuals with acute low-back pain.
Ten of the participants received chiropractic adjustments. Ten underwent a sham procedure. Specifically, “in the treatment group, a traditional chiropractic manipulation (lumbar roll technique with a pisiform contact on the ipsilateral mamillary of L5) was delivered, whereas with the sham group, the same technique was used, but no thrust was applied.”
Infrared cameras were used to measure paraspinal skin temperature bilaterally at the L5 level. These measurements were taken 2 minutes before the intervention. They were repeated immediately following the intervention, and again 1, 3, 5 and 10 minutes later.
Among experimental subjects, skin temperature on the side of the spine receiving the adjustment warmed up by 0.2°F immediately following the adjustment. After 3 minutes, “the treatment side warmed by approximately 0.6°F, whereas the contralateral side (nontreatment side) cooled.” On the other hand, there were no significant changes in skin temperature to either side in control subjects.
“The effects of a lumbar spine manipulation appear noticeable by changes in paraspinal CT measurements at the level of L5,” conclude the study’s authors. “However, the meaning and mechanisms of CT modifications at L5 are still being investigated.”

Scoliosis Surgery Implants Increase Blood Levels of Chromium
Stainless steal rods and screws are used in the common scoliosis surgery known as instrumented spinal arthrodesis. However, the stainless steal implants may expose patients to dangerous levels of toxic chemicals, say scientists.
The researchers conducted blood tests on three groups of people. Group 1 included 30 patients who underwent spinal arthrodesis for scoliosis. Group 2 included 10 individuals with scoliosis who did not have surgery. Group 3 included 10 people without scoliosis.
Results revealed that “elevated above normal serum chromium levels were demonstrated in 11 of 30 (37%) group 1 participants. Elevated serum chromium levels were demonstrated in 0 of 10 participants (0%) in group 2 and 1 of 10 (10%) in group 3.”
The article concludes that “this new finding has relatively unknown health implications but potential mutagenic, teratogenic and carcinogenic sequelae. This is especially concerning with most scoliosis patients being adolescent females with their reproductive years ahead.”

Burger Consumption Linked With Childhood Asthma
Frequent burger consumption may up the risk of asthma, according to a study of 50,000 children. Specifically, children who eat three or more burgers per week have an elevated risk of asthma and wheezing. Conversely, a Mediterranean diet high in fish and fruit appears to prevent asthma.
Curiously, a diet high in any type of meat was not linked with asthma. Consequently, the study’s authors suggest that the link may be due to lifestyle factors, rather than beef itself.

Elective C-Section Linked With Learning Disorders
Elective caesarean delivery is linked with an elevated risk of learning disabilities, including autism and dyslexia.
The study included 407,503 school-aged children in Scotland. Overall, 4.9% of these youngsters required special needs education (SEN). Babies born at 40 weeks had a 4% risk of learning disabilities. In contrast, those delivered “early term” between 37 to 39 weeks — a large portion of which are Caesarean deliveries — had a 5.1% risk of learning disorders.
Although the risk of SEN was much higher in preterm than in early term babies, because many more children were born between 37 and 39 weeks (about a third of babies) than before 37 weeks (1 in 20 babies), early term births accounted for 5.5% of cases of SEN whereas preterm deliveries accounted for only 3.6% of cases. And, results show that even a baby born at 39 weeks has an increased risk of SEN compared with a baby born a week later.
“Our findings have important implications for clinical practice in relation to the timing of elective delivery,” say the authors.

Second-Hand Smoke Tied With Mental Problems
People who are exposed to second-hand smoke are more likely to have psychological problems, compared with people who are not exposed to second-hand smoke.
These findings are from a study that looked at 5,560 non-smokers and 2,595 smokers. None of the subjects had a family history of mental illness. The non-smokers underwent saliva testing for exposure to second-hand smoke. Overall, 14.5% of study participants complained of psychological distress. Compared with non-smokers, smokers had a 2.45-fold increased risk of mental problems. And, a direct correlation was evident between exposure to second-hand smoke and risk of psychological distress. Specifically, non-smokers who were exposed to the highest levels of second-hand smoke were 62% more likely to suffer from psychological problems.
Over six-years of follow-up, smokers were 3.7 times more likely to be admitted to a psychiatric hospital, compared with people not exposed to smoke. Second-hand smokers were 2.8 times more likely to be admitted to a psychiatric hospital, compared with people who were not exposed to second-hand smoke.
