The Tobacco Connection Revealed. At the end of the Second World War the link between smoking and lung cancer was not widely recognized. The rapid increase in the frequency of lung cancer was a cause of some concern but doctors were among the heaviest smokers, and smoking as a cause was, oddly enough, overlooked. How the connection was made has been recently summarized by Sir Richard Doll, who was closely involved and the following account is based largely on his report.Tobacco had been in use for over three hundred years, but it was probably the advent of cigarettes at the beginning of the twentieth century that started the lung cancer epidemic. Perhaps the clearest warning had been sounded by a researcher named Pearl from Johns Hopkin’s University in the United States in a scientific paper in 1938 in which he reported that, ‘the smoking of tobacco was statistically associated with an impairment of life duration and the amount and degree of the impairment increased as the habitual amount of smoking increased’. Before the war, therefore, Pearl had told us that smoking shortened life and that the more we did it the more it was likely to do so, but nobody took much notice.The change in attitudes can be dated to 1950 when five reports of the tobacco-cancer link were made and Sir Richard Doll and Sir Austen Bradford Hill concluded that smoking caused lung cancer. There was a change in approach to examining the relationship; and large studies, drawing on all the skills of epidemiologists, were established to follow large numbers of individuals over several years. By 1954 it was very clear that smoking caused lung cancer. Doctors played a part here in twoways. Doll and Hill were the investigators but one important group of subjects consisted of doctors. When it looked likely that smoking caused lung cancer, many doctors stopped quickly. Showing that this group then became less likely to get cancer than those who continued to smoke was a strong piece of evidence.From that time on links between smoking and other diseases, including heart attacks and other cancers, were increasingly demonstrated, and the complex interaction between the three thousand different chemicals to be found in tobacco smoke and the dozens of illnesses with which tobacco is now associated began to unfold.*39\194\4*

Assessment of renal function can provide information for early detection and monitoring of nephrotoxic treatments. Measurements of renal function that can provide information related to the etiology, site of injury, current activity, extent, and potential reversibility of nephrotoxicity are needed. Traditional screening tests of renal function (blood urea nitrogen, serum creatinine, and urine output) are inadequate.As always in pediatric patients, carefully consider the importance of age-related reference values and physiologic developmental variations. Although rarely applicable in oncology clinical trials, the dynamic early postnatal renal changes can complicate treatment with potentially nephrotoxic medications.A. Radioisotopic techniques”Tc-diethylene pentacetic combines low patient radiation dosimetry (40 mrad/mCi) and good correlation with inulin clearance. Using a compartmental analysis model, calculate glomerular filtration rate (GFR) after a single bolus injection of radioisotope. The two-compartment model has an error of approximately 3-4 mL/min when compared with inulin clearance. Errors in measurement can be introduced by edema, intravascular volume contraction or expansion, or severe renal failure. A correction factor for volume of distribution can be used.B. ElectrolytesScreening for renal tubular dysfunction should include serum potassium, sodium, chloride, glucose, magnesium, phosphate, alkaline phosphatase, bicarbonate, and pH. To aid interpretation of these values, corresponding evaluation of urine lytes is required. Screening for distal renal tubular function should include osmolality and pH of an early morning urine sample. Proximal tubular damage is associated with aminoaciduria and glucosuria.*33\168\2*

MOTHERS WITH THE HIGHEST LEVELS OF PBBMothers with the highest levels of PBB in their blood, who also breast-fed their daughters, produced girls with the earliest menstruation, the study says.”PBBs … do get concentrated in breast milk,” Marcus says, “because the chemical binds to fat cells and breast milk has a very high fat content.”Girls who received both in utero and breast milk exposure to the chemical started their periods at the average age of 11.6, which was a full year earlier than other girls who were not exposed.Little is known about exactly how PBBs might affect the onset of puberty, although experts say it is known that thechemical binds to estrogen receptors and that PBBs and poly-chlorinated biphenyls (PCBs) affect the thyroid gland.The reason that this is important from a public health point of view is that it demonstrates that this type of chemical may be causing early puberty, and there a lot of other chemicals in the environment that are more widely disseminated that may be acting similarly. So, while the cause of this incidence of accelerated sexual development can be traced back to chemical causes, no one really knows why the body is responding this way.It is becoming evident that environmental estrogen mimics are speeding up the sexual development of girls. In boys, however, it’s another story. Anti-androgenic chemicals seem to be slowing down sexual development of boys. There’s no doubt about it however, we are tampering with nature. Both little girls and little boys are being affected.*68/165/1*

You are probably wondering why your practitioner can’t tell by a blood test whether or not your cancer has spread through the bloodstream. Remember how tiny the cancer cells are? They travel fn the blood singly or in very small groups and there are only very few of them in the bloodstream at any one time. This means that the chances of actually seeing them in a small sample of blood are minute. The only way we can know they have been in the bloodstream is by finding secondary growths in other parts of the body.

There are also some types of cancer which develop in many different places throughout the body from the start. These cancers include leukaemias, myeloma and many lymphomas. Leukaemias and myeloma begin in the bone marrow. The bone marrow is where we form new blood cells. In a child it occupies most bones but in adults it is concentrated in the central bones—spine, ribs, skull, pelvis and upper parts of arms and legs. Because leukaemias and myeloma are cancers of certain types of white blood cells, they begin where those white cells are normally formed, which is throughout the bone marrow. With leukaemias, the cancerous white blood cells can be found in a blood sample whereas in most cases of myeloma they are not released into the blood and can be found only in a bone marrow specimen.

The lymphomas are a group of cancers which originate in the lymph system. Most of these appear in many different nodes at the same time. There are some types, such as Hodgkin’s disease, which tend to spread in a fairly orderly and predictable way from one group of nodes to another and, in some cases, can be successfully treated with radiation therapy directed only to the affected parts of the body.
