Two hundred and eighteen randomly selected doctors drawn from among the faculty and students of Postgraduate Institute of Medical Education and Research; Interns and staff at the General Hospital; and General practitioners of the Chandigarh city, were administered a structured questionnaire. Among them 31.6% were current smokers whereas 23.3% had stopped smoking (ex-smokers). All but one of the smokers were men who smoked cigarettes. Spirit of experimentation and peer influence were important initiating factors whereas the habit was continued mainly to concentrate on work/study. Doctors were uniformly aware of the detrimental effects of smoking, particularly its association with lung cancer, chronic bronchitis and coronary artery disease, and this was the major reason for their abstaining or wanting to quit the habit. The relation of smoking with oral cancer, laryngeal cancer, emphysema and peripheral vascular disease was not well appreciated. Counselling patients about hazards of smoking was practised significantly less often by smoking doctors and surgeons. The options favoured by doctors for preventing smoking included a ban on tobacco advertising, specific health warning on cigarette/bidi packs, and restriction of smoking in public places, particularly hospitals and clinics.

A case is reported of a laryngeal cancer recurrence that had invaded and then eroded the pharynx. The fistula produced was the cause of a thrombophlebitis of upper limb, and subcutaneous emphysema limited to the right shoulder region due to radiosclerosis of soft tissues of neck.

Cigarette smoking is the primary preventable cause of various diseases and death. Smoking has been causally related to lung cancer, other malignancies, atherosclerosis, coronary heart disease, and chronic obstructive pulmonary disease. There have been few studies, however, of whether the ordinary citizen in Japan understand the risks of serious diseases caused by smoking. Four hundred and thirty six people attended a seminar of respiratory diseases entitled "Cigarette smoking and lung cancer; prevention and treatment of asthma; senile care and prevention of pneumonia". After the seminar, unsigned questionnaires were filled out by 403 of those in attendance. Three hundred eighty nine (165 males and 224 females) respondents correctly answered the questionnaires, and these were analyzed in the study. Attendants comprised 243 who had never smoked (63%), 99 former smokers (25%), and 39 current smokers (10%). Three hundred forty seven attendants (89%) answered that smoking is harmful to the health, and 371 (95%) that it is causally related to lung cancer. In contrast, lower numbers of attendants answered that smoking is causally related to other diseases: pulmonary emphysema, 65% of the responses; chronic bronchitis, 68%; laryngeal cancer, 77%; myocardial infarction, 53%; and atherosclerosis, 49%. Of the 39 current smokers, 27 answered that they would stop smoking after the seminar. Although many people partly understand the risks of smoking, they do not have a clear knowledge of the risks of diseases besides lung cancer. Education about the risks of smoking and about smoking cessation is required.

Postoperative infection has influence on costs, quality of life, and outcome of the disease. It is suspected that post-total laryngectomy infections have increased in frequency and seriousness, because of the failure of the preservation protocol or the previous radiotherapy, making rescue surgery necessary. The objective of this study was to develop a predictive model of infection based on the pre- and intrasurgical variables considered risky. One hundred fifty five patients with E III-IV laryngeal cancer, with 24.8:1 male to female ratio (mean age, 58 years) who underwent total laryngectomy were evaluated for uni- and multivariate analysis of age, sex, histological grade, primary or recurrent disease, tobacco, alcohol, diabetes, tuberculosis/chronic emphysema, red and white cell counts, erythrosedimentation rate (ESR), albumin, chemotherapy, neck radiotherapy and/or previous surgery, confinement days, type and time of surgery, which were factors in the infection event. A predictive model of infection was developed and included albuminemia (<3.5 g%), >1 liter of alcohol daily, and exclusive surgery of the primary. The sensitivity was 90.5% and the specificity 68%. The variance reached 29.6%. The causes of infection were multiple, having analyzed only 30% of them. However, the resulting model was classified correctly in 83.2% of cases. A careful preoperative assessment, an adjusted planning of the surgery, an appropriate use of antibiotics, and a meticulous operative technique are needed to prevent infection.

Environmental carcinogens contained in air pollution, such as polycyclic aromatic hydrocarbons, aromatic amines or N-nitroso compounds, predominantly form DNA adducts but can also generate interstrand cross-links and reactive oxygen species. If unrepaired, such lesions increase the risk of somatic mutations and cancer. Our study investigated the relationships between 22 polymorphisms (and their haplotypes) in 16 DNA repair genes belonging to different repair pathways in 1094 controls and 567 cancer cases (bladder cancer, 131; lung cancer, 134; oral-pharyngeal cancer, 41; laryngeal cancer, 47; leukaemia, 179; death from emphysema and chronic obstructive pulmonary disease, 84). The design was a case-control study nested within a prospective investigation. Among the many comparisons, few polymorphisms were associated with the diseases at the univariate analysis: XRCC1-399 Gln/Gln variant homozygotes [odds ratios (OR) = 2.20, 95% confidence intervals (CI) = 1.16-4.17] and XRCC3-241 Met/Met homozygotes (OR = 0.51, 95% CI = 0.27-0.96) and leukaemia. The recessive model in the stepwise multivariate analysis revealed a possible protective effect of XRCC1-399Gln/Gln in lung cancer (OR = 0.22, 95% CI = 0.05-0.98), and confirmed an opposite effect (OR = 2.47, 95% CI = 1.02-6.02) in the leukaemia group. Our results also suggest that the XPD/ERCC1-GAT haplotype may modulate leukaemia (OR = 1.28, 95% CI = 1.02-1.61), bladder cancer (OR = 1.38, 95% CI = 1.06-1.79) and possibly other cancer risks. Further investigations of the combined effects of polymorphisms within these DNA repair genes, smoking and other risk factors may help to clarify the influence of genetic variation in the carcinogenic process.

A 73-year-old male with marked emphysema was admitted to the 2nd Department of Internal Medicine, University Hospital in Krakow because of chronic obstructive pulmonary disease (COPD) exacerbation. His medical history was significant for total laryngectomy due to laryngeal cancer in 2010.
