Uninsured Individuals Research has shown that uninsured individuals have higher unmet medical needs than do insured individuals birth control 6 month shot buy online alesse, and those without insurance also have higher rates of substance use disorders than do individuals with insurance birth control facts buy alesse 0.18 mg visa. These funds also fnance treatment for people without insurance and support community prevention activities birth control pills 35 years old cheap alesse 0.18mg fast delivery. Grants are used to birth control for women xxxl buy alesse 0.18mg low cost increase screening, counseling, workplace wellness See Chapter 3 Prevention Programs programs, and community prevention. Prevention should be seen as an appropriate health cost to be covered by insurance. Current funding options for community prevention, described below, include grants from hospital and health system foundations, hospital-based community beneft programs, tax earmarks, and targeted state programs. Hospital and Health System Foundation Grants Foundations formed from the conversion of tax-exempt non-proft hospitals and health systems into for-proft entities are required by federal law to invest in health-related activities within the community area served by that hospital. Tax-exempt hospitals must: (1) conduct a community health needs assessment at least once every 3 years; (2) involve public health experts and representatives of the community served by the facility in the needs assessment; (3) make the results of the assessment available to the public; (4) develop an implementation strategy to address each of the community health needs identifed through the assessment; and (5) report yearly to the Internal Revenue Service. Although hospitals have fexibility in their defnition of “community served by the facility,” they are expected to defne community by the geographic location, not by the demographic or geographic profles, of patient discharges. Many states also have community beneft programs that must be synchronized with the requirements of the Affordable Care Act. It was renewed for seven years in 2009, and the one-quarter of one-cent sales tax generates over $20 million per year. The funds are used for a variety of prevention, treatment, and anti-drug and drug-related crime prevention programs. In addition, Florida and Indiana, among other states, earmark alcohol taxes for child and adolescent substance use-related services. Funded through a one-time $57 million assessment, the Trust Fund is used to reduce the prevalence of preventable health conditions and lower health care costs. Grantees have a strong focus on extending care beyond clinical sites into the community. However, several key challenges must be addressed if integration is to be fully successful. The Infrastructure of the Substance Use Disorder Treatment System Is Underdeveloped the Congressional Budget Ofce currently estimates that by 2026, 24 million Americans who would otherwise be uninsured will obtain health insurance coverage as a result of the Affordable Care Act. Fifty-fve percent of addiction treatment patients in expansion states are receiving care in organizations that at least have contractual linkages to some medical or health home arrangement. Because these organizations have traditionally been organized and fnanced separately from general health care systems, the two systems have not routinely exchanged clinical information. For example, private, for-proft treatment facilities were signifcantly more likely to be early adopters of buprenorphine therapies than were their public or private non-proft peers. Medical homes are most likely to pursue contractual arrangements with large and technologically sophisticated organizations that are best equipped to meet their needs for timely clinical and administrative information. Yet, the same patterns may harm smaller providers, some of whom offer the only culturally competent services for particular patient groups, such as services tailored for specifc racial and ethnic populations, sexual and gender minorities, or women in need of trauma-related residential services. A study of 2009–2010 national treatment center data found that only 25 percent of substance use disorder treatment centers offered medications for alcohol and/or drugs: 24. For example, one study found that only three percent of United States treatment programs used it for opioid use disorders. A recent study found that raising this limit further, rather than increasing the number of specialty addiction programs or waivered physicians, may be the most effective way to increase buprenorphine use. Major pediatric medical organizations, including the American Academy of Pediatrics, strongly recommend addressing these issues regularly at each well-adolescent visit and appropriate urgent care visits. The Affordable Care Act requires health plans to cover, at no out-of-pocket cost to families, the preventive care services outlined in this schedule. Bright Futures discusses how to incorporate screening into the preventive services visit for these age groups. The Joint Commission Requirements mandate that hospitals offer inpatients brief counseling for alcohol misuse and follow-up, and measure the provision of counseling as one of the core measures for hospital accreditation. The Health Care Workforce Is Limited in Key Ways Workforce Shortages Data on the substance use workforce are incomplete. Nevertheless, it is clear that the workforce is inadequate, as evidenced by its uneven geographic distribution (with rural areas underserved), access barriers for adolescents and children, and recruitment challenges across the treatment feld. A recent study documented stafng models in primary care practices and determined that, even among those designated as patient-centered medical homes, fewer than 23 percent employed health educators, pharmacists, social workers, nutritionists, or community service coordinators, and fewer than half employed care coordinators. In practice, the Block Grant is used broadly, and Medicaid less and only with a subset of providers. It is not yet clear whether the integration of substance use disorder treatments in general health care will help to address salary structure. Composition and Education An integrated health and substance use disorder treatment system requires a diverse workforce that includes substance use disorder specialists, physicians, nurses, mental health treatment providers, care managers, and recovery specialists. As substance use disorder treatment and general health care become more integrated, clinical staff in both systems will need to expand their scope of work, operate in an integrated manner with a variety of populations, and shift their treatment focus as needed. Health care professionals moving from the specialty workforce into integrated settings will require specifc training on treatment planning and care coordination and an ability and willingness to work under the leadership of medical staff. This transition to a highly collaborative team approach, offering individually tailored treatment plans, presents challenges to the traditional substance use disorder treatment workforce that is used to administering standard “programs” of services to all patients. Working in teams with the broad mandate of improved health is not currently commonplace and will require collaboration among professional and certifcation bodies. Incorporating peer workers, who bring specifc knowledge of patients’ experiences and needs and can encourage informed patient decision making, into teams will also require further adjustment. Improving the Quality of Health Care for Mental and Substance Use Conditions also discussed the shortage of skills both in specialty substance use disorder programs and in the general health care system. Workforce Development and Improvement the Annapolis Coalition on the Behavioral Health Workforce provided a framework for workforce development in response to the challenges described above,318 focusing on broadening the defnition of “workforce” to address needed changes to the health care system. Currently, 66 organizations license and credential addiction counselors,319,320 and although a consensus on national core competencies for these counselors exists,321 they have not been universally adopted. Credentialing for prevention specialists exists through the International Certifcation & Reciprocity Consortium,322,323 but core competencies for prevention professionals have not been developed. Without a comprehensive, coordinated, and focused effort, workforce expansion and training will continue to fall short of the challenge of meeting the needs of individuals across the continuum of service settings. Of particular note is the National Health Service Corps, where, as of September 2015, roughly 30 percent of its feld strength of 9,683 was composed of behavioral health providers, meeting service obligations by providing care in areas of high need. The development of the workforce qualifed to deliver these services and services to address co-occurring medical and mental disorders will have signifcant implications for the national workforce’s ability to reach the full potential of integration. Protecting Confdentiality When Exchanging Sensitive Information Effectively integrating substance use disorder treatment and general health care requires the timely exchange of patient health care information. In the early 1970s, the federal government enacted Confdentiality of Alcohol and Drug Abuse Patient Records (42 U. These privacy protections were motivated by the understanding that discrimination attached to a substance use disorder might dissuade people from seeking treatment, and were enacted in the context of patient methadone records being used in criminal cases. Given the long and continuing history of discrimination against people with substance use disorders, safeguards against inappropriate or inadvertent disclosures are important. Disclosures to insurers or to employers can render patients unable to obtain disability or life insurance and can cost patients their jobs. However, exchanging treatment records among health care providers has the potential to improve treatment and patient safety. For example, in the case of opioid prescribing, a study in health systems of long-term opioid users found those with a prior substance use disorder diagnosis received higher dosages and were co-prescribed sedative-hypnotic medications—which can increase the risk for overdose—more often. Because of privacy regulations, it is likely that physicians were not aware of their patients’ substance use disorders. Promising Innovations That Improve Access to Substance Use Disorder Treatment Clearly, integrating health care and substance use disorder treatment within health care systems, as well as integrating the substance use disorder treatment system with the overall health care system, are complex undertakings. In so doing, they are broadening the focus of interventions beyond just the treatment of severe substance use disorders to encompass the entire spectrum of prevention, treatment, and recovery. Medicaid Innovations Medicaid is not only an increasing source of fnancing for substance use disorder treatment services, it has become an important incubator for innovative substance use disorder fnancing and delivery models that can help integrate substance use disorder treatment and mainstream health care systems. Within the substance use disorder treatment beneft, and in addition to providing the federally required set of services, states also may offer a wide range of recovery-oriented services under Medicaid’s rehabilitative services option.

The Tenth Revision is the product of international activity, cooperation and compromise. There are many possible axes of classification and the one selected will depend upon the use to be made of the statistics to be compiled. Following suggestions, at the time of development of the Ninth Revision of the classification, that a different basic structure might better serve the needs of the many and varied users, several alternative models were evaluated. These are known as "inclusion terms" and are given, in addition to the title, as examples of the diagnostic statements to be classified to that rubric. This usually occurs when the inclusion terms are elaborating lists of sites or pharmaceutical products, where appropriate words from the titles. Glossary descriptions In addition to inclusion or exclusion terms, Chapter V, Mental and behavioural disorders, uses glossary descriptions to indicate the content of rubrics. To enclose supplementary words, which may follow a diagnostic term without affecting the code number to which the words outside the parentheses would be assigned. Brace } A brace is used in listings of inclusion and exclusion terms to indicate that neither the words that precede it nor the words after it are complete terms. For example, "mitral stenosis" is commonly used to mean "rheumatic mitral stenosis". Careful inspection of inclusion terms will reveal where an assumption of cause has been made; coders should be careful not to code a term as unqualified unless it is quite clear that no information is available that would permit a more specific assignment elsewhere. Symbols † the dagger symbol is used to indicate a code that represents the etiology or underlying cause of a disease. This code should be paired with a dagger (etiology) code and should follow this in sequence. Even with a new structure, it was plain that one classification could not cope with the extremes of the requirements. Various schemes involving alphanumeric notation had been examined with a view to producing a coding frame that would give a better balance to the chapters and allow sufficient space for future additions and changes without disrupting the codes. This had the effect of more than doubling the size of the coding frame in comparison with the Ninth Revision and enabled the vast majority of chapters to be assigned a unique letter or group of letters, each capable of providing 100 three-character categories. The order of entry of chapters in the proposals for the Tenth Revision had originally been the same as in the Ninth Revision; however, to make effective use of the available space, disorders of the immune mechanism were later included with diseases of the blood and blood-forming organs, whereas in the Ninth Revision they had been included with endocrine, nutritional and metabolic diseases. During the elaboration of early drafts of the chapter on "Diseases of the nervous system and sense organs", it had soon become clear that it would not be possible to accommodate all the required detail under one letter in 100 three-character categories. Some new features of the proposals for the Tenth Revision were as follows: • the exclusion notes at the beginning of each chapter had been expanded to explain the relative hierarchy of chapters, and to make it clear that the "special group" chapters had priority of assignment over the organ or system chapters and that, among the special group chapters, those on "Pregnancy, childbirth and the puerperium" and on "Certain conditions originating in the perinatal period" had priority over the others. Postprocedural conditions that were not specific to a particular body system, including immediate complications such as air embolism and postoperative shock, continued to be classified in the chapter on "Injury, poisoning and certain other consequences of external causes". The dual classification scheme for etiology and manifestation, known as the dagger and asterisk system, introduced in the Ninth Revision, had been the subject of a certain amount of criticism. Some issues related to changes in chapter structure and content were discussed by the Conference and agreement reached on follow-up and modification by the secretariat. In order to improve the quality of maternal mortality data and provide alternative methods of collecting data on deaths during pregnancy or related to it, as well as to encourage the recording of deaths from obstetric causes occurring more than 42 days following termination of pregnancy, two additional definitions, for "pregnancy-related deaths" and "late maternal deaths", were formulated by the working party. The Conference was further informed that additional notes for use in underlying cause coding and the interpretation of entries of causes of death had been drafted and were being reviewed. As these notes were intended to improve consistency in coding, the Conference agreed that they would also be incorporated in the Tenth Revision. The Conference noted the continued use of multiple-condition coding and analysis in relation to causes of death. In considering the international form of medical certificate of cause of death, the Expert Committee had recognized that the situation of an aging population with a greater proportion of deaths involving multiple disease processes, and the effects of associated therapeutic interventions, tended to increase the number of possible statements between the underlying cause and the direct cause of death: this meant that an increasing number of conditions were being entered on death certificates in many countries. Experience gained in the use of the definitions and rules in the Ninth Revision had proved their usefulness and generated requests for their clarification, for further elaboration regarding the recording of diagnostic information by health care practitioners, and for more guidance on dealing with specific problem situations. The Conference agreed that extensive notes and examples should be added to provide further assistance. Two versions of the general mortality list and of the infant and child mortality list had been prepared for consideration by the Conference, with the second version including chapter titles and residual items for chapters as necessary. The report of the working party was accepted by the Conference and is reflected in the mortality lists on pages 1207-1220. Considerable concern was expressed about the applicability of such lists to all morbidity in the broadest sense. It was also agreed that, to facilitate the alternative tabulation of asterisk categories, a second version of the morbidity tabulation list should be developed, which included the asterisk categories. Field trials of this system had been carried out in countries of the Region and the results used to revise the list of symptom associations and the reporting forms. The Consultation on Primary Care Classifications (Geneva, 1985) (7) had stressed the need for an approach that could unify information support, health service management and community services through information based on lay reporting in the expanded sense of community-based information. It was stated that the publication of a new version was unlikely before implementation of the Tenth Revision. The aim of the list was to identify procedures and groups of procedures and define them as a basis for the development of national classifications, thereby improving the comparability of such classifications. The main criteria for selection of that name were that it should be specific, unambiguous, as selfdescriptive and simple as possible, and based on cause wherever feasible. Subjects proposed for future volumes included psychiatric diseases, as well as diseases of the skin, ear, nose and throat, and eye and adnexa. As the title implies, classification of diseases or conditions, this chapter is intended to be temporary. This may take a number of forms, as in the following examples: Inflammation bone see Osteomyelitis this indicates that the term "Inflammation, bone" is to be coded in the same way as the term "Osteomyelitis". On looking up the latter term, the coder will find listed various forms of osteomyelitis: acute, acute hematogenous, chronic, etc. When a term has a number of modifiers which might be listed beneath more than one term, the cross-reference (see also. Enlargement, enlarged see also Hypertrophy If the site for enlargement is not found among the indentations beneath "Enlargement", the indentations beneath "Hypertrophy" should be referred to, where a more complete list of sites is given. Bladder see condition Hereditary see condition As stated previously, anatomical sites and very general adjectival modifiers are not usually used as lead terms in the Index and one is instructed to look up the disease or injury reported on the medical record and under that term to find the site or adjectival modifier. If the medical record includes more precise information the coding should be modified accordingly. Special signs the following special signs will be found attached to certain code numbers or index terms: †/* Dagger and asterisk used to designate the etiology code and the manifestation code respectively, for terms subject to dual classification. The "sequelae" include conditions specified as such; they also include late effects of diseases classifiable to the above categories if there is evidence that the disease itself is no longer present. A neoplasm that overlaps two or more contiguous sites within a three-character category and whose point of origin cannot be determined should be classified to the subcategory. On the other hand, carcinoma of the tip of the tongue extending to involve the ventral surface should be coded to C02. The introductory pages of Volume 3 include general instructions about the correct use of the Alphabetical Index. This departure from the principle that categories should be mutually exclusive is deliberate, since both forms of terminology are in use but the resulting anatomical divisions are not analogous. Excludes: hypothyroidism resulting from administration of radioactive iodine (E89. When one or more previous measurements are available, lack of weight gain in children, or evidence of weight loss in children or adults, is usually indicative of malnutrition. When only one measurement is available, there is a high probability of severe wasting when the observed weight is 3 or more standard deviations below the mean of the reference population. Includes: acute or subacute: • brain syndrome • confusional state (nonalcoholic) • infective psychosis • organic reaction • psycho-organic syndrome Excludes: delirium tremens, alcohol-induced or unspecified (F10.

Since these children have not eaten for a day or so and probably have vomited, dehydration and contraction of the extracellular space is an important consideration. If dehydration is severe and peritonitis is present, the bladder must be catheterized to monitor urine output as a reflection of adequacy of fluid administration. It is not unusual that three or four times the maintenance rate of electrolyte rich fluid is required for extracellular repletion and adequate blood volume support. Those patients with peritonitis should have particular encouragement to cough and deep breathe to prevent atelectasis and pneumonia as abdominal pain and distention cause elevation and splinting of the diaphragm leading to inadequate lung expansion and retention of secretions. In cases of right lower quadrant pain and tenderness what is the second most frequent system implicated as its causefi Literally "middle pain" caused by a ruptured ovarian follicle which occurs approximately in mid-menstrual cycle. His mother carried him and he settled down after a few minutes and then fell back asleep. His abdomen is soft and not distended, with normoactive bowel sounds, and no masses noted. After a short nap, he is able to tolerate oral fluids and his behavior normalizes. Intussusception is best described as a portion of the intestine which telescopes into a more distal intestinal segment. It is often difficult to diagnose because of the variable presentation of symptoms in a young infant. The most common type of intussusception is ileocolic (also known as ileocecal) (90%). A portion of terminal ileum intussuscepts through the ileocecal valve into the colon. Other types of intussusception that are rarer include ileoileal, colocolic, and ileoileocolic. An anatomic lead point (a piece of intestinal tissue which protrudes into the bowel lumen such as a polyp) occurs in approximately 10% of intussusceptions. Intussusceptions with lead points are more common in patients with Henoch-Schonlein purpura (intestinal wall hematoma) and cystic fibrosis (hypertrophied mucosal glands). The mesentery is pulled along with the intussusceptum (leading invaginating segment) into the intussuscipiens (receiving segment). The intussusceptum becomes engorged causing bleeding from the mucosa (bloody mucusy stools, sometimes known as currant jelly stool since extreme amounts of blood in the stool will loosely resemble the red jelly of currant berries). However, it should be noted that any blood in the stool may be caused by an intussusception. With a prolonged intussusception, perfusion to the intestine may be compromised, which can then lead to bowel necrosis, perforation, and shock. The classic triad of intussusception include crampy (intermittent, also known as colicky) abdominal pain, vomiting, and bloody stools. The classic triad was found in only 21% of cases and two symptoms were found in 70% of cases in one series of patients with intussusception (1). Patients with an intussusception may also present with lethargy/altered level of consciousness and pallor. The etiology of this lethargic presentation is not known, but it tends to occur in younger infants. Some hypothesize that this is due to release of endogenous opioids or endotoxins released from ischemic bowel. Intussusception in a child presenting with lethargy is often difficult to diagnose since other causes of lethargy such as dehydration, hypoglycemia, sepsis, toxic ingestion, post-ictal state, etc. The physical examination of a patient with an intussusception may be unremarkable. If the patient is between attacks of the crampy abdominal pain, he may appear normal and the abdominal examination may be unrevealing. Also, examining the abdomen of an active or Page 385 crying child can often be difficult. A sausage-like mass in the right upper quadrant and emptiness (the absence of bowel) in the right lower quadrant is clinically indicative of an intussusception. If the intussusception has been present for a longer period of time, the abdomen may be distended and there may be findings of peritonitis. There are several findings described on plain film abdominal radiographs of patients with intussusception. There may be evidence of a soft tissue mass or signs of bowel obstruction (air fluid levels and distended loops of bowel). The absence of gas in the right lower quadrant or flank may be seen with an intussusception. A target sign is viewing the intussusception on cross-section which appears as two concentric circles (created by bowel fat density differences) usually in the right upper quadrant. The crescent sign is formed by the leading edge of the intussusception outlined by gas in the colon forming a crescent (intussusceptum protruding into a gas filled pocket). The absent liver margin sign can be seen if the soft tissue mass of the intussusception is resting at the hepatic flexure of the colon or there is absence of gas in the right upper quadrant making the lower edge of the liver indistinct. Free air may be visible on the radiograph if there has been intestinal perforation. More recently, ultrasound has been advocated as it is highly specific (100%) and sensitive (98%) in making the diagnosis of intussusception, but only when interpreted by highly skilled radiologists. The major problem with utilizing ultrasound is that it must be able to definitively rule out intussusception, since if diagnostic uncertainty still exists following the ultrasound, a contrast enema must still be performed. Additionally, if the ultrasound does identify an intussusception, a contrast enema must still be performed to reduce the intussusception. Thus, before considering an ultrasound, the diagnostic ultrasonography skills of the available radiologist must be determined. The high specificity and sensitivity percentages are published from studies done in ultrasound pediatric super centers and thus, these numbers are not necessarily applicable to general radiologists. A barium enema has been the gold standard in the past for confirming the diagnosis and nonsurgical reduction of an intussusception. Water-soluble contrast has been used and more recently air enema reduction has been introduced. There are several reasons why radiologists have different preferences for which type of contrast they choose to use for the procedure. After the radiologist reduces the intussusception, they look for the contrast to reflux into the ileum. This is more difficult to see with an air contrast enema compared to a barium or water-soluble contrast enema. Air leaking into the peritoneal cavity because of intestinal perforation may also be difficult to see. Those in favor of using the air contrast enema technique argue that with perforation, the sudden loss of pressure would signal to the radiologist to stop the procedure. If a tension pneumoperitoneum results, this should be decompressed immediately with an 18-gauge needle. An air contrast enema is advocated as the preferred method by many pediatric radiologists (2), but since there is no clear consensus among radiologists of the best contrast enema option, this decision is best left to the radiologist performing the contrast enema procedure. Several factors are associated with a contrast enema being unsuccessful in reducing the intussusception. These include ileo-ileocolic intussusception, longer duration of symptoms (>12 hours), dehydration, small bowel obstruction, and age greater than 2 years or less than 3 months. The intussusception being present for 24 hours or more, is no longer a contraindication for attempting contrast enema reduction. The rate of intestinal perforation with nonsurgical reduction of an intussusception is 1% to 3%. A contrast enema is contraindicated in patients who have a bowel perforation, shock, or peritonitis. Ultrasound has also been used to monitor reduction of the intussusception using saline rather than contrast under fluoroscopy. If the intussusception is not reduced by an enema, or if there is intestinal perforation, shock, or peritonitis present, the patient is sent for surgical reduction. An intravenous line, a nasogastric tube, and consultation with a surgeon should be considered.

Alterations in the occurrence of laryngeal cancer and location of the tumours inside the larynx during the study period of 1962-1991 2. Comparison of epidemiological aspects, clinical behaviour and prognosis between glottic and supraglottic carcinoma 4. Case histories of 309 patients were available in the hospital archives and all of them were also reported to the Cancer Registry. Information of nine cases diagnosed during the 1960s was available only in the Cancer Registry. These patients were either treated elsewhere or the records had been deleted from the hospital files. In all patients with records available in the hospital files, the diagnosis was confirmed by histological examination. In addition, 30 patients (15 supraglottic, 13 glottic and 2 subglottic) were excluded from the survival analyses, 5 due to insufficient follow-up data and 25 because their potentially curative primary or salvage treatment was abandoned for other than cancer-related reasons. Because of the small number of subglottic cases, most analyses by tumour site were not performed among them. In incidence rates for periods of several years, the mean population of the corresponding period was used. To allow for the change in the age distribution of the population during the study period and to enable adequate comparisons with other studies, the incidence rates were adjusted for age according to the world standard population (Doll et al. In groups with skewed distributions, the Mann-Whitney U test and Kruskall-Wallis analysis of variance were employed. Symptom duration was calculated from the beginning of the earliest symptom reported by the patient to the date of the diagnostic biopsy; the length of each symptom was also recorded separately. Patients living without known recurrence and those who died of intercurrent diseases were censored at the last follow-up or at the date of death, respectively. In multivariable analyses, the variable selection was based on a stepwise procedure where a variable was entered into the model at a significance level of 0. Ethics the study was carried out according to the approval of the Ethics Committee of Tampere University Hospital. Four verrucous carcinomas, one pseudosarcomatous and one adenosquamous carcinoma were found. The annual number of new cases of laryngeal carcinoma varied between 4 and 25 (mean 10. However, due to the decrease of occurrence in men, the male to female incidence ratio decreased from 38:1 in 1962-71 to 18:1 in 1982-91. The occurrence increased with age in both sexes and the age-specific incidence was higher among males than females in all age groups older 35 than 35 years. The peak incidence was in the age group 65-69 years in males and 75-79 years in females (I. The site-specific incidence rates for males indicate that the decrease of occurrence was largely due to the significant (p<0. In the first 5-year period 1962-66, the glottic to supraglottic incidence ratio for males was 0. In both sexes the proportion of smokers was significantly higher among the patients than in the whole population. Moderate/nondrinkers had a supraglottic tumour in 43% of cases and a glottic one in 56%. The socio-economic distribution of the 291 evaluable male patients differed significantly from that of the whole male population: there were 2. Hoarseness was more commonly associated with glottic and subglottic tumours, although it was the most frequent symptom also in supraglottic cases. Supraglottic tumours caused a markedly higher occurrence of sore throat, dysphagia, globus, otalgia and haemoptysis. These findings were independent of the differences in stage distribution between tumour sites. About 10% of patients having a supraor subglottic lesion presented with a neck mass noticed by the patient, which was the only symptom in two cases. At the time of diagnosis, regional lymph node metastases were present in 21% of patients with a 37 supraglottic tumour but only in 2% of those with a glottic lesion. The proportion of T1-2 tumours decreased from 72% to 64% and that of T3-4 lesions increased from 28% to 36% from the first to the last ten-year period. To further classify the extent of the disease, involvement of the anterior, middle and posterior third of each vocal cord was estimated separately (V, Table 2). None of these 76 patients had regional or distant metastases at the time of diagnosis and only two had a neck node relapse. Methods of obtaining the diagnostic biopsy Method n (%) Indirect laryngoscopy, local anaesthesia 1 (0. Jet ventilation was first used in 1972, and after 1978 intratracheal jet ventilation has been the primary ventilation technique. Most (20) unsuccessful biopsies were obtained by direct laryngoscopy in local anaesthesia, and the proportion of failures (23%) was significantly higher than that of direct laryngoscopy in general anaesthesia (7%, p=0. Due to the small number of failures, the differences in the percentage of failed biopsies between the other methods of laryngoscopy could not be analysed. In these early supraglottic cases, radiotherapy was often combined with the operative treatment, which usually also included a neck dissection. Of the 10 patients with subglottic disease, 4 39 had primary radiotherapy while 6 underwent total laryngectomy and neck dissection, in 5 patients combined with radiotherapy. Of the 166 patients treated with primary radiotherapy, 104 (63%) had a glottic T1 or T2 tumour and 27 (16%) a supraglottic T1-2 lesion. Eighty-two (96%) of the 85 glottic T1 and 22 (58%) of the 38 glottic T2 tumours were treated with primary irradiation. In the 76 cases treated by the megavoltage techniques, the total dose ranged from 45 Gy to 70 Gy, normalized to minimum target-absorbed dose. Except for three patients treated during the last years of the study period, radiotherapy was delivered by split-course technique with a pause of 1-3 weeks in the middle of the treatment. Surgery Total (n=84) and supraglottic (n=39) laryngectomy were the most common primary operations. In addition, 3 laryngopharyngectomies, 2 hemilaryngectomies and 2 chordectomies using thyrotomy approach were performed. Combined treatment Out of the 94 patients treated with a combination of surgery and irradiation, 36 had preoperative and 51 postoperative radiotherapy. Preoperative radiotherapy was used particularly in the 1970s and early 1980s, and often the final decision on operative treatment was made according to radiation response in the middle or at the end of the radiotherapy. When patients with a transglottic tumour were excluded from the analysis, the prognosis was significantly better in glottic than in supraglottic disease (5-year survival 89% vs. This significance was, however, lost when the survival was adjusted for Tcategory. Several tumourrelated variables had a significant effect on locoregional control and survival in univariate analyses (V, Table 4). In the multivariate analysis of primary locoregional control, only the number of vocal cord thirds involved (V. None of the 14 female patients treated with curative intent died of their carcinoma. No significant difference was found between radiotherapy and surgery or between surgery and combined treatment. Multivariate analysis of prognostic factors the prognostic factors were further evaluated by multivariate Cox regression analysis of disease-specific survival including the variables age, year of diagnosis, tumour site, T-category, N-status (N0/N+), treatment modality (radiotherapy/surgery/combined) and mode of 43 radiotherapy (X-ray/other/none). It is, however, possible that in the early years both the diagnostics and the recording of cancers were less accurate and some cases may have been missed. In women the occurrence has remained practically unchanged, the mean annual age-adjusted incidence being 0. In the present patient population from the Tampere University Hospital the incidence trend was parallel with the nation-wide figures, but the numbers were somewhat lower: among men the highest 5-year average incidence was 6. In most previous studies, increasing occurrence trends have been observed among both sexes, and often the female incidence has increased faster (Ayiomamitis 1989, DeRienzo et al.
