Oral health status in a group of the elderly population residing at home

doi: 10.1111/j.1741‐2358.2011.00556.x Oral health status in a group of the elderly population residing at home Objectives: To determine the oral health status and treatment needs of subjects aged 65 years and older residing in different districts of Ankara. Materials and methods: A total of 1300 patients, 751 females and 549 males, age 65 and over with a mean age of 72.8 ± 6.34 were included in this study. The subjects were visited at home and toothbrushing habits, visiting the dentist, tooth loss, denture needs were questioned and body mass index values were recorded. Results: 52.5% of the subjects were completely edentulous, 83.3% subjects reported wearing a removable denture. Females had a higher total tooth loss frequency when compared to males (p < 0.05). Total tooth loss between 65 and 69 ages was 47.3%, and increased to 62.4% among those aged 75 and over (p < 0.05). 16.2% of the subjects had not visited a dentist in the last 10 years, and only 3% visited a dentist for control check‐ups; no gender‐based difference was observed as to the frequency of dental visits (P > 0.05). No significant relationship was found between tooth loss and BMI values (P > 0.05). 46.3% of the subjects had chewing problems. Conclusions: The subjects included in this study showed high tooth loss frequency and poor oral hygiene habits. Education regarding maintenance of oral hygiene and regular dental check up should be stressed for the elderly.     

An unusual case report: Tinea capitis,verrucae vulgares and other infections in a girl with T and B cell disturbances

Hereby described is a case of a young girl suffering from widespread dermatophytosis caused byTrichophyton violaceum which proved intractable to accepted methods of therapy throughout a number of years. The girl was also found to have a history or recurrent respiratory tract infection and pyoderma in addition to verrucae vulgares, and Giardia lamblia in the gastrointestinal tract. Investigation revealed a marked immunological deficit seen in both the cellular and humoral system. It is suggested that in similar cases resistant to therapy it may be helpful to carry out a comprehensive investigation of the immunological system.     

A study of 3891 cases of mycoses in the tropics.

4103 cases suspected of mycoses were analysed as to sex, age and site of disease and 3891 were proved cases. This group formed 50% of total mycoses or 13-93% of all dermatoses recorded in the Government General Hospital, Madras, during the period of study. There were 66-26% adult female, 27-6% adult male and 6-14% were below 13 years. Dermatophytoses were found in 73-5%; the other common diseases were tinea versicolor (17-68%) and candidiasis (12-43%). Multiple sites of involvement or more than 1 disease in the same individual were mostly observed. The incidence of piedra (0-1%) and deep mycoses (0-156%) was very low. Mycetoma was the common disease (5/6) in deep mycoses. In dermatophytoses, tinea corporis (49-71%) and tinea cruris (47-85%) commonest; tinea axillaris (3-42%), tinea capitis (1-72%) and tinea barbae (1-29%) were less common. The incidence of tinea manuum, tinea pedis and tinea unguium was similar (4-97%-6-38%). High temperature and humidity were related to the higher incidence of tinea corporis, tinea cruris and tinea versicolor. Mainly children suffered from tinea capitis. All other mycoses were commonly found in adults between 2nd and 3rd decades. In all mycoses but candidiasis, female predominated. Cutaneous candidiasis was mainly a problem of housewives. Among the dermatophytes Trichophyton violaceum was predominant (33-7%) followed by T. rubrum (32-6%). Trichophyton schoenleinii and M. gypseum were rarely isolated. From mycetoma, Madurella mycetomii, Nocardia braziliensis, N. asteroides and Actinomadura spp. were isolated. Demonstration of Cryptococcus laurentii in 1 case is reported in this area for the first time.     

The effect of surgery with cardiopulmonary bypass on oxygen transport in elderly patients with ischemic heart disease

In a clinical trial, 103 patients undergoing coronary artery bypass grafting from May, 1999, to December, 2001 with hypothermic cardiopulmonary bypass (CPB) were retrospectively assigned to one of two groups: group I (n = 45)--patients 65 years of age and older (68.0 +/- 0.5), group II (n = 58)--patients 45-50 years of age (48.2 +/- 0.2). The following parameters were recorded: haemodynamic--with thermodilution method (SMU--612, Hellige), blood gases (OMNI-6, Austria). Measurements were performed 7 times: (1) before surgery, (2) before CPB, (3) after CPB, (4, 5, 6, 7)--1, 3, 9, 12 hours after surgery. Indexes of oxygen delivery and consumption, oxygen utilization coefficient and anion gap were calculated. Obtained results were statistically analyzed using appropriate t-test and chi2-test for categorical variables. Data are expressed as mean +/- SE. There were no significant differences between the groups in all stages of examination, p > 0.05. In elderly group both oxygen delivery and consumption were lower then in younger one, thus the coefficient of oxygen utilization did not differ between groups. Therefore the surgery with CPB seems to be inrelated to adverse changes on oxygen transport in elderly patients, and its dynamic was similar in patients over 65 years of age and younger group.     

Maxillofacial fractures in the elderly: a comparative study

Previous maxillofacial trauma research has dealt primarily with facial bone fractures in the general population. Very few studies have specifically addressed maxillofacial fractures in the elderly. We compared 45 elderly (65 years of age or older) and 201 younger adult (16 to 64 years of age) patients admitted to our hospital with maxillofacial fractures. The percentage of patients admitted with nasal bone fractures was much greater in the elderly population, while mandibular fractures were more common in the adult group. Motor vehicle accidents accounted for over half the injuries in both groups, while falls were more prevalent in the elderly. Management of the elderly patient may be complicated by their associated injuries or underlying medical problems, perhaps partially accounting for their longer median length of hospital stay. The elderly are a unique subpopulation of maxillofacial fracture patients and deserve further study regarding their injuries and optimal methods for treatment.     

How to fit allergen immunotherapy in the elderly

Asthma, allergic rhinitis (AR) and atopic dermatitis are very common in young people, but in the latest decades it was increasingly recognized that also individuals of higher ages, including the population over 65 years, are concerned. Actually, it is now acknowledged the aging does not considerably alter the immune response to allergens. Allergen immunotherapy (AIT) is the only treatment that works on the causes of allergy, but elderly people are commonly excluded from AIT, except the cases of insect sting allergy. A number of recent studies showed that aged individuals also successfully respond to AIT for respiratory allergy. Therefore, there is no reason to exclude elder patients from AIT. Anyhow, clinical conditions that are considered absolute or relative contraindications are quite frequent in this aged population, thus the risk/benefit ratio must be carefully evaluated for each patient, taking into account that the more frequent occurrence of co-morbidities and the consequent need of daily-based multidrug regimen can favor adverse effects. An important issue concern the ability of AIT, and particularly of sublingual immunotherapy, to significantly improve the quality of life, that often is particularly impaired in the elderly, reducing symptoms and drugs consumption.     

Prevalencia de los trastornos de ansiedad en las personas mayores de 65 años: una revisión sistemática

Anxiety is an emotional problem that causes discomfort and suffering to those that suffer from it. Anxiety disorders can affect the functioning in different facets of a person's life. Studies on the prevalence of anxiety disorders in people over 65 years show variable results, ranging between 0.1% and 17.2%. Most of these studies include samples of the general population, in which the population of people over 65 years is under-represented. These studies evaluate older people with the same diagnostic tools used to assess anxiety disorders in people under 65 years, and collect data from people between 65 and 75 years old, leaving out people aged 75 and over. A systematic review of the prevalence studies of anxiety disorders in elderly people is presented. It is concluded that when representative samples of people over 65 years are used and evaluated with suitable tools, the prevalence rate of these disorders in the elderly is much higher than previously thought, reaching an annual prevalence rate of 20.8%.     

Observations on the Antipruritic Effect of Guanethidine in Atopic Dermatitis

Guanethidine, 0.75 to 1.25 mg. per kg. per day, was found to alleviate the pruritus of acute atopic dermatitis in 19 out of 20 patients. It was not effective in patients with other dermatoses. An apparent partial tolerance to this treatment developed in six out of 10 patients re-treated. It had little or no therapeutic effect in 10 patients with a variety of other pruritic dermatoses, suggesting that this drug has a specific antipruritic action in patients with atopic dermatitis. In a double-blind study, 11 of 12 patients with atopic dermatitis treated with guanethidine experienced relief of pruritus. Four out of 12 patients using a placebo had complete or partial relief. Guanethidine, 1% to 10%, used topically was therapeutically no more effective than placebo. In view of the reported side effects and the anesthetic hazard encountered with guanethidine, further long-term studies are indicated before this drug is adopted for clinical use in the treatment of atopic dermatitis. The findings support the hypothesis that atopic dermatitis may be a manifestation of a hereditary defect in cutaneous noradrenaline binding.     

Opportunistic invasive mycoses in AIDS. An autopsy study of 211 cases.

The opportunistic mycoses are an important cause of morbidity-mortality among patients with severe immunosuppression provoked by HIV. We present a study of 211 serial autopsies of patients with HIV/AIDS infection carried out by our service in a period of 10 years, observing frequency of invasive mycoses of the 44.1%. Pneumocystis carinii infection was the most frequent (32%) with a prevalence of lung affection. Candidiasis follows it in order of frequency with 31.1%, predominantly the oropharyngeal manifestation. Systemic or cerebromeningeal cryptococcosis were serious and common disorder (29%). Diseminated histoplasmosis occurred in 9.6% and in three cases (3.2%) pulmonary aspergillosis was diagnosed as a postmortem discovery in cavity lesions. In our series, other less common HIV-associated were not identified.     

Prevalence of oral mucosal lesions in an elderly population in the city of Valparaiso,Chile

doi: 10.1111/j.1741‐2358.2012.00663.x Prevalence of oral mucosal lesions in an elderly population in the city of Valparaiso, Chile Objective: Chilean population is ageing, which means an increase in the prevalence of multiple pathologies, including those located in the oral cavity. Aim: To measure the prevalence and distribution of oral mucosal lesions and to identify associated risk factors in elderly patients in the city of Valparaiso. Material and methods: This study includes 126 patients over 60 years. The sample was calculated with a sampling error of 3.7% from a population size of 6000 file cards. Frequency and contingency tables were made together with odds ratios, with a confidence interval of 95%. Finally, we built a predictive model based on a binary logistic regression. Results: From the whole sample, 85 patients (67.5%) had some oral mucosal lesion. The most frequent lesions were denture‐induced stomatitis (37.1%). It was noted that there is a statistically significant association between the use of denture and the presence of oral candidiasis. The consumption of drugs and the use of denture increase the likelihood of having oral mucosal lesions. Conclusion: There is a high prevalence of oral lesions in the elderly patients of Valparaiso. The use of drugs and /or denture increases significantly the likelihood that a person over 60 years presents lesions in the oral mucosa.     

Diagnostic Value of Symptom Screening for Pulmonary Tuberculosis in China

ObjectiveTo evaluate the diagnostic value of symptom screening for tuberculosis (TB) case finding defined in National Tuberculosis Control Program in China (China NTP) among elderly people(≥65 years) and younger people(<65 years).MethodsWe made a secondary analysis in a population-based TB prevalence survey in China in 2010. Questionnaire including information for cough and haemoptysis was completed by face to face interview, and then chest radiography was conducted in all eligible participants. Sputum smear and culture were followed for all TB suspects. We calculated the odds ratios (OR), sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and the area under the receiver operating characteristic curve (AUC) of using different symptoms for screening to detect bacteriologically positive TB in subpopulations stratified by age 65, to evaluate the performance of symptom screening for TB.FindingsOf 315 newly diagnosed bacteriologically positive TB, 131 patients (41.59%) were elderly, and 48.57% of TB patients were asymptomatic. Nearly 50% patients did not present cough of any duration, and less than half present cough more than 2 weeks, a defined suspected symptom in China NTP. Cough of any duration was reported more in patients aged under 65 than those in elderly, especially for the acute cough (9.78% vs 6.87%). Those symptoms defined by China NTP were reported by less than half participants in two subpopulations. Acute cough (<2 weeks) was an independent predictor of TB in people aged under 65 (adjusted OR: 3.3, 95% CI: 2.0-5.5), but not in those aged 65 and above (adjusted OR: 1.4, 95% CI: 0.7-2.9). The specificity for each symptom was significantly higher in participants aged under 65 (P<0.01), and sensitivities of most symptoms were significantly higher among elderly (P<0.05 or P<0.01). When compared with cough for 2 weeks and more, using cough of any duration for symptom screening increased the sensitivity from 42.9% to 51. % for all participants, and the AUC increased from 0.70 to 0.74 for participants aged under 65 without significant difference.ConclusionsThere is a high percent of asymptomatic TB patients, and those symptoms adopted in China NTP for screening is poorly predictive for TB. The presence of TB symptoms, the sensitivities and specificities of symptoms for TB were distinct between two subpopulations cut by age 65, implying different case finding strategies should be established for them. The current case finding strategy should be improved, and further studies should be done to evaluate the performance and cost-effectiveness of different symptom screening strategy.     

The impact of the 2008 cold spell on mortality in Shanghai, China

No prior studies in China have investigated the health impact of cold spell. In Shanghai, we defined the cold spell as a period of at least seven consecutive days with daily temperature below the third percentile during the study period (2001–2009). Between January 2001 and December 2009, we identified a cold spell between January 27 and February 3, 2008 in Shanghai. We investigated the impact of cold spell on mortality of the residents living in the nine urban districts of Shanghai. We calculated the excess deaths and rate ratios (RRs) during the cold spell and compared these data with a winter reference period (January 6–9, and February 28 to March 2). The number of excess deaths during the cold spell period was 153 in our study population. The cold spell caused a short-term increase in total mortality of 13 % (95 % CI: 7–19 %). The impact was statistically significant for cardiovascular mortality (RR?=?1.21, 95 % CI: 1.12–1.31), but not for respiratory mortality (RR?=?1.14, 95 % CI: 0.98–1.32). For total mortality, gender did not make a statistically significant difference for the cold spell impact. Cold spell had a significant impact on mortality in elderly people (over 65 years), but not in other age groups. Conclusively, our analysis showed that the 2008 cold spell had a substantial effect on mortality in Shanghai. Public health programs should be tailored to prevent cold-spell-related health problems in the city.     

West Indian diabetic population of a large inner city diabetic clinic.

West Indians form a sizable minority of diabetics attending many inner city diabetic clinics. There are 554 diabetics of West Indian origin on our computer files--7% of the total recorded clinic population. Of these 554 patients (56% female, 44% male), 70% have been diagnosed within the past five years; and only 9% have had diabetes for over 10 years; in only five (1%) was diabetes diagnosed before the age of 20. Sixteen per cent were taking insulin, but only 4% of the total West Indian population were truly insulin dependent. Of 65 patients admitted in hyperglycaemic coma or precoma over the past three years, 10 were of West Indian origin; eight of these 10 had hyperosmolar coma compared with only six of the remaining 55. We conclude that diabetics of West Indian origin attending our clinic show differences in the distribution of age and duration of diabetes from the caucasian population. Most are non-insulin dependent, and the frequency of hyperosmolar coma is higher than that of ketoacidosis. Diabetics of West Indian origin may have a different pattern of disease from the rest of the clinic population.     

The safety of microvascular free tissue transfer in the elderly population

The objective of this study was to evaluate the safety and thus the efficacy of microvascular free tissue transfer in the elderly patient population. Free flaps for different types of reconstructions were analyzed to verify whether free tissue transfer is feasible in the elderly. Between 1993 and 2003, 102 free flaps were performed in 94 patients who were aged 70 years or older. There were 75 male and 19 female patients, with a mean age of 73.8 years (range, 70 to 87 years). Different types of free flaps were performed for head and neck (n = 78), lower extremity (n = 12), and trunk and upper extremity (n = 4) reconstruction. Nine flaps underwent reexploration and four of them were lost, for an overall success rate of 96 percent. Medical complications in the postoperative period were further evaluated. A total of 32 medical complications were seen in 29 patients. Only one patient died because of postoperative complications. The frequency of medical complications was further analyzed in detail. Effects of American Society of Anesthesiologists status, operation time, and age on complication rate were evaluated statistically. Only American Society of Anesthesiologists status was statistically significant for the occurrence of postoperative medical complications; class III and IV patients were at higher risk than class I and II. Neither operation time nor age was predictive of postoperative complications. Microvascular free tissue transfer is a safe and reliable option in the elderly population. The success rate of free flaps is not different from that for other age groups. The rate of postoperative medical complications was 31 percent (29 of 94 patients); most complications were in American Society of Anesthesiologists class III and IV patients.     

Allelotyping the Hras1 minisatellite: formation of carcinogenic risk groups and predicting the course of non-small cell lung cancer]

PCR-based typing of Hras1 minisatellite alleles was carried out in 226 non-small cell lung cancer (NSCLC) patients and 207 unaffected controls. Application of this method permitted detection of four common (a1 to a4) and 25 other alleles, differing from any common allele by one or more repeat units. Depending on their frequency in control group, these alleles were defined as intermediate or rare (the frequency over 0.5% or less than 0.5%, respectively). It was established that the frequency of rare alleles in the group of NSCLC patients (7.1%) was statistically significantly higher than in healthy individuals (2.2%, p = 0.002), while the difference in the distribution of common and intermediate alleles between the compared groups was not statistically significant. In addition, rare Hras1 alleles were more frequent (p = 0.02) among nonsmoking patients compared to the patients subjected to of tobacco carcinogens. The presence of "heavy" (a3-a4) alleles was associated with an increased risk of low-differentiated and/or actively metastasizing tumors and also with the risk of lung cancer in the patients under 50 years of age (p < 0.05). These data indicate that an approach including application of modern highly sensitive techniques of Hras1 allele typing in combination with preliminary examination of healthy control population can be employed for identifying carcinogenic risk groups as well as for prognosis of the NSCLC clinical course.     

Use of vitamin B12 injections among elderly patients by primary care practitioners in Ontario

BACKGROUND: Excess use of parenteral vitamin B12 has been reported from audits of clinical practices. The authors assessed the use of vitamin B12 injections in patients aged 65 years and over in Ontario. METHODS: A cross-sectional analysis was conducted that included all elderly people covered by the Ontario Health Insurance Plan who received insured services from general practitioners or family physicians (GP/FPs). For each practice the proportion of elderly patients who received regular vitamin B12 injections between July 1996 and June 1997 was calculated. The frequency of injections was determined for each patient receiving regular B12 replacement. RESULTS: Of the 1,196,748 elderly patients (mean age 74.8 [standard deviation 6.8], 58.0% female) treated by 14,177 GP/FPs, 23,651 (2.0%) received regular B12 injections. The rate of B12 injections per patient, standardized for age and sex, varied between practices (range 0%-48.6%). Although no authoritative sources support the practice, 3303 (19.8%) of the 16,707 patients receiving long-term parenteral therapy had, on average, overly frequent injections (more than 1 injection every 4 weeks). For 76 (12.3%) of the 617 practices with 10 or more patients receiving regular vitamin B12 injections, the mean injection frequency was greater than once every 4 weeks. The proportion of patients in these 617 practices who received overly frequent injections varied extensively (0%-100%). INTERPRETATION: Our findings indicate that some primary care physicians in Ontario administer unnecessary vitamin B12 injections to elderly patients.     

Aging, cancer, and cancer vaccines

ABSTRACT: World population has experienced continuous growth since 1400 A.D. Current projections show a continued increase - but a steady decline in the population growth rate - with the number expected to reach between 8 and 10.5 billion people within 40 years. The elderly population is rapidly rising: in 1950 there were 205 million people aged 60 or older, while in 2000 there were 606 million. By 2050, the global population aged 60 or over is projected to expand by more than three times, reaching nearly 2 billion people 1. Most cancers are age-related diseases: in the US, 50% of all malignancies occur in people aged 65-95. 60% of all cancers are expected to be diagnosed in elderly patients by 2020 2. Further, cancer-related mortality increases with age: 70% of all malignancy-related deaths are registered in people aged 65 years or older 3. Here we introduce the microscopic aspects of aging, the pro-inflammatory phenotype of the elderly, and the changes related to immunosenescence. Then we deal with cancer disease and its development, the difficulty of treatment administration in the geriatric population, and the importance of a comprehensive geriatric assessment. Finally, we aim to analyze the complex interactions of aging with cancer and cancer vaccinology, and the importance of this last approach as a complementary therapy to different levels of prevention and treatment. Cancer vaccines, in fact, should at present be recommended in association to a stronger cancer prevention and conventional therapies (surgery, chemotherapy, radiation therapy), both for curative and palliative intent, in order to reduce morbidity and mortality associated to cancer progression.     

Onychomycosis in Cali,Colombia

This study presents the epidemiological and mycological aspects of 299 patients with nail lesions who were referred to three diagnostic laboratories in the city of Cali. The diagnosis of mycoses was established through visualization of mycotic structures in a direct microscopic examination of skin scrapings and by isolation. Onychomycosis was found in 183 cases (61.2%), of which 141 were in toenails (44 in males and 97 in females), 38 in fingernails (9 males and 29 females), and 4 cases in toenails and fingernails simultaneously (all females). No statistically significant relation was found between sex and onychomycosis. Yeasts accounted for 40.7% of the mycoses, dermatophytes for 38%, nondermatophyte molds for 14% and the etiology was mixed in the remaining cases (7.3%). Candida albicans was the most commonly isolated yeast species; the most common dermatophyte was Trichophyton rubrum and Fusarium spp. and Scytalidium dimidiatum were the most common nondermatophytic molds. Them common fungi found in fingernails were yeasts; in toenails dermatophytes were more prevalent (chi2 with Yates' correction = 19.75, P= 0.000088). Yeasts were observed more frequently in females while dermatophytes were more common in males. The difference between these two etiologic groups was statistically significant (chi2 with Yates' correction = 7.43, P = 0.0064); no relation was observed according to age.     

Outcome in colorectal adenocarcinoma: two seven-year studies of a population.

OBJECTIVE--To record every patient with proved colorectal adenocarcinoma presenting from a defined population over two years in 1968-9 and during 1980-2, and to compare treatment and outcome over seven years. DESIGN--Retrospective in 1968-9 and prospective in 1980-2. SETTING--Aberdeen general hospitals. SUBJECTS--Every patient presenting to the four general surgical units with histological proof of colorectal adenocarcinoma. MAIN FINDINGS--On average, one new patient presented each week per 100,000 population. The proportion of patients aged 65 and over rose from 67% to 71%. An operation was performed on 385 patients in 1968-9 and on 399 during 1980-2. At laparotomy the proportion of patients who seemed to be curable and had a radical operation rose slightly, from 56% to 61%, and operative mortality fell from 9% to 5%. In all there were 421 survivors of curative surgery, and seven years later three quarters were either alive (51%) or had died without recurrence (25%). In both studies some 40% of patients were considered incurable when they presented, but the number who had a palliative resection rose from 59% to 85%. CONCLUSIONS--The contribution of radical surgery to the treatment of colorectal adenocarcinoma is substantial, with three quarters of patients so treated showing no evidence of recurrence after seven years. Operative mortality in an elderly population is now low, and improvement in late outcome is more likely to come from developments in adjuvant therapy than in operative technique. A continuing problem is that 40% of patients are not curable when they present, although palliative resection can now be offered to over 80%.     

Low levels of ill health among elderly non-consulters in general practice.

The characteristics of random samples of elderly patients (over 65 years of age), designated as consulters (n = 200) and non-consulters (n = 196), in a group general practice were compared using a postal questionnaire that was validated by comparison with findings by general practitioners in a random sample of 58 responders. A response rate of 90% was obtained, and all non-responders were visited by their general practitioner. The questionnaire had a sensitivity of 79% and a specificity of 82% when compared with general practitioner findings. The use of hospital and social services by non-consulters was low in this practice. Measures of disability and state of health showed that non-consulters were a fit group of the aged. Case finding for problems among elderly people should initially be confined to consulters, who have a high prevalence of problems. Non-consulters are a low risk group that can be assessed only with special effort and extra resources. Once an effective case finding system has been developed it might then be reasonable to consider ways of finding the few patients who have problems but do not consult their doctor.
