´Feet are second class citizens`: exploring the perceptions of Scottish and Portuguese older adults about feet, falls and exercise- a qualitative study.

INTRODUCTION: Foot problems are likely to contribute to falls risk in older adults. Foot and ankle exercises may be beneficial, but uptake may be influenced by cultural factors. Few studies have explored the views of older adults from different cultural backgrounds about foot-specific falls risk factors, and foot and ankle falls prevention exercises. OBJECTIVES: To explore the views of Scottish and Portuguese community-dwelling older adults who have experienced a fall, about any foot risk factors for falls, and foot and ankle exercises. METHODS: Cross-cultural qualitative study with (n = 6) focus groups exploring the perceptions of Scottish (n = 10, mean age 76 yrs) and Portuguese older adults (n = 14, mean age 66 years) aged, applying thematic analysis. RESULTS: One main theme `evolving awareness about feet and falls prevention´ and three subthemes; (i) Feet are often forgotten, (ii) the important role of footwear, (iii) need to look at my feet and do the exercises were identified. Scottish participants had more experience of falls prevention but there was a lack of knowledge surrounding foot-specific falls risk factors, and the role of ankle and foot exercise in the prevention of falls. Portuguese participants exhibited a fatalistic approach to falls. CONCLUSIONS: Older adults from both nations had little knowledge of foot-specific falls risk factors, being initially unaware of the functional status of their feet and of the role of exercise in foot care and falls management. There were differences between national groups that should be accounted for when developing culturally adequate interventions.

Foot health among the Roma population of southern Spain according to the foot health status questionnaire.

BACKGROUND: Foot health of the Roma population is a challenge for the health professionals where this minority is significant, as is the case in Spain. At present, little is known about foot health of the Roma population and their knowledge would promote the training of these professionals at the community level. Foot pain is common and a reason for consulting podiatry services. The purpose of this study was to determine foot health among the Roma population according to the Foot Health Status Questionnaire. METHOD: An observational, cross-sectional and quantitative study conducted at the Roma population living in Spain in 2018. Self-reported data and the Foot Health Status Questionnaire were recorded. Examining the general health and foot health (foot pain, foot function, footwear and general health) and general (general health, social capacity, physical activity and vigour). This questionnaire is recommended as a valid and reliable patient-reported outcome. The obtained scores were compared. RESULTS: A sample made up of 624 men and women from the Roma population took part in this study. 45% were Roma men and 55% Roma women. In the first section of the FHSQ, a lower score of values was recorded in the footwear domain (62.5) and in the general foot health domain (60). Gypsy women obtained lower scores in all the domains. In the second section, lower scores were obtained in the vigour (56) domain and in the general health (60) domain. A large effect size (r-Rosenthal) was found by gender in the footwear domain (0.334) and in the vigour domain (0.195). Roma women showed higher values in cardiac disorders, serious illnesses, doctor visits and foot problems. 67.8% reported that they had never been assisted by a podiatrist. CONCLUSIONS: The studied Roma population has foot health problems, and these are more pronounced among women. They show lower values in the footwear and vigour domains. More professional training is required for health workers in this field to avoid cultural diversity stereotypes.

Acral melanoma foot lesions. Part 1: epidemiology, aetiology, and molecular pathology.

Acral melanoma (AM) is a rare subtype of cutaneous malignant melanoma (MM) found on acral skin, primarily on the soles of the feet. Although rare, it is the most common subtype of MM found in patients of African or East Asian ethnicity and has a poor prognosis, often because of the more advanced stage of presentation at diagnosis. The pathogenesis of AM is unclear, but genetic alterations, including mutations in BRAF, NRAS, and KIT have been implicated. Early diagnosis of AM is important for a better prognosis, but its identification is often challenging, leading to easy misdiagnosis. In the first of this two-part review, we review the history, epidemiology, aetiology and molecular pathology of AM; in part 2 we will review diagnosis and management.

Racial differences in foot disorders and foot type.

OBJECTIVE: To describe racial differences in the frequency of structural foot disorders and pes planus and pes cavus foot types in a large cohort of African American and white men and women ages ≥50 years. METHODS: Of 1,695 Johnston County Osteoarthritis Project participants evaluated for foot disorders/types in 2006-2010, 4 with lower extremity amputation were excluded, leaving 1,691 available for analyses (mean age 69 years, mean body mass index [BMI] 31.5 kg/m(2) , 68% women, 31% African American). The most common foot disorders/types were identified using a validated foot examination. Each foot disorder/type was compared by race using logistic regression, controlling for age, BMI, and sex. Effect modification between race (African American versus white) and age, BMI (categorized as ≥30 kg/m(2) [obese] or <30 kg/m(2) [nonobese]), sex, and education was examined. RESULTS: Hallux valgus (64%), hammer toes (35%), overlapping toes (34%), and pes planus (23%) were common. Compared to whites, African Americans were almost 3 times more likely to have pes planus and were nearly 5 times less likely to have Tailor's bunions or pes cavus. Among the nonobese, African Americans were more likely than whites to have hallux valgus (adjusted odds ratio [OR(adj) ] 2.01, 95% confidence interval [95% CI] 1.39-2.92), hammer toes (OR(adj) 2.64, 95% CI 1.88-3.70), and overlapping toes (OR(adj) 1.53, 95% CI 1.09-2.13). CONCLUSION: Foot disorders are common among adults ages ≥50 years and differ by race. Future research is needed to determine the etiology of foot problems, especially those with racial differences, in order to inform prevention approaches.

Multiple primary acral melanomas in African-Americans: a case series and review of the literature.

BACKGROUND: Although melanoma accounts for only 4% to 5% of all skin cancers in the United States, it causes most skin cancer-related deaths. We describe a unique group of African-American patients with multiple primary acral lentiginous melanomas (ALMs). OBJECTIVE: The purpose of this study was to review the case histories and management of a cohort of patients in the Mohs practice of our dermatologic surgeon with multiple primary ALM. METHODS: This is a case series of patients with multiple ALM identified by chart review from 2000 to 2005. A thorough review of the literature was performed. RESULTS: Four patients, all African-American, were identified with multiple ALM. All patients were managed with excision or Mohs micrographic surgery utilizing permanent sections. None of the patients with ALM had melanomas at nonacral sites or other types of skin cancer. Several had acral melanosis. Information in the literature on patients with multiple primary acral melanomas was insufficient. CONCLUSION: Patients with multiple acral melanomas have not, to our knowledge, been reported thus far. It can be extrapolated from current literature, however, that appropriate management of these patients, including staging work and surgical intervention, is to be determined by the individual characteristics of the melanoma and the patient's concomitant risk factors, if any.

Classic Kaposi's sarcoma in the Inuit of northern Quebec.

BACKGROUND: Classic Kaposi's sarcoma (KS) is predominantly a disease of eastern Mediterranean and Ashkenazi Jewish elderly men. Nevertheless, the disease has been reported to occur in people from various other ethnic and regional backgrounds. OBJECTIVE: We report, for the first time, the occurrence of classic KS in five Inuit people living in northern Quebec, Canada. METHODS AND RESULTS: We describe the case of a 69-year-old Inuit man with classic KS, and report four other cases of KS in the Inuit population, identified by a review of our hospital's dermatopathology records. CONCLUSION: The discovery of classic KS in the Inuit population of northern Quebec brings with it new questions as to the origins of the KS-associated herpes virus in this population. It is our belief that the answers to these questions are in the genotype of the virus that is present in this community.

Prevalence of foot and ankle conditions in a multiethnic community sample of older adults.

The prevalence of foot and ankle disorders was determined in a community-based, multiethnic (non-Hispanic White, African American, and Puerto Rican) random sample of 784 community-dwelling adults aged 65 or more years in 2001-2002 in Springfield, Massachusetts. Overall, the five most common conditions were toenail disorders (74.9%), lesser toe deformities (60.0%), corns and calluses (58.2%), bunions (37.1%), and signs of fungal infection, cracks/fissures, or maceration between toes (36.3%); 30.9% had some tenderness to palpation of the foot or ankle, and 14.9% had ankle joint pain on most days in the past 4 weeks. Toenail conditions, fungal symptoms, and ulcers or lacerations were more common in men, while bunions and corns and calluses were more common in women (p < 0.001). Significant racial/ethnic differences, independent of education or gender, were found for the prevalence of most toe deformities and flat feet, as well as for corns and calluses, fungal signs, edema, ankle joint pain, tenderness to palpation, and sensory loss. Foot and ankle disorders are common in these older adults. Examination of their prevalence in different segments of the community may inform future studies to determine etiology and means of prevention.

[Squamous cell carcinoma in neuropathic plantar ulcers in leprosy: another example of Marjolin's ulcer]. / Plaveiselkarsinoom in neuropatiese plantare ulkusse van leprose: nog 'n voorbeeld van Marjolin se ulkus.

Seven cases of squamous cell carcinoma (SCC) arising in chronic neuropathic plantar ulcers of leprosy are described. These patients (average age 59 years) presented over a 5-year period. The mean duration of neuropathic ulceration until diagnosis of SCC was 24.5 years. Six patients required limb amputations and 3 underwent lymphadenectomy for involved nodes. One patient died of disseminated disease. The history of the eponym "Marjolin's ulcer' is traced and a case put forward for recognition of malignant change in neuropathic ulcers as yet another example of Marjolin's ulcer. A plea is made for an increased awareness of the possibility of malignant transformation in chronic neuropathic ulcers in order to effect an early diagnosis of a potentially aggressive cancer. This is the first report of its kind in South Africa. Similar cases, however, have been reported from other parts of the world where leprosy is endemic.

A foot risk classification system to predict diabetic amputation in Pima Indians.

OBJECTIVE: To quantify the contribution of various risk factors to the risk of amputation in diabetic patients and to develop a foot risk scoring system based on clinical data. RESEARCH DESIGN AND METHODS: A population case-control study was undertaken. Eligible subjects were 1) 25-85 years of age, 2) diabetic, 3) 50% or more Pima or Tohono O'odham Indian, 4) lived in the Gila River Indian Community, and 5) had had at least one National Institutes of Health research examination. Case patients had had an incident lower extremity amputation between 1983 and 1992; control subjects had no amputation by 1992. Medical records were reviewed to determine risk conditions and health status before the pivotal event that led to the amputation. RESULTS: Sixty-one people with amputations were identified and compared with 183 control subjects. Men were more likely to suffer amputation than women (odds ratio [OR] 6.5, 95% CI 2.6-15), and people with diabetic eye, renal, or cardiovascular disease were more likely to undergo amputation than those without (OR 4.6, 95% CI 1.7-12). The risk of amputation was almost equally associated with these foot risk factors: peripheral neuropathy, peripheral vascular disease, bony deformities, and a history of foot ulcers. After controlling for demographic differences and diabetes severity, the ORs for amputation with one foot risk factor was 2.1 (95% CI 1.4-3.3), with two risk factors, 4.5 (95% CI 2.9-6.9), and with three or four risk factors, 9.7 (95% CI 6.3-14.8). CONCLUSIONS: Male Sex, end-organ complications of eye, heart, and kidney, and poor glucose control were associated with a higher amputation rate. Peripheral neuropathy, peripheral vascular disease, deformity, and a prior ulcer were similarly equally associated with an increased risk of lower extremity amputation.

Multiple agminated pigmented Spitz nevi (mimicking acral lentiginous malignant melanoma and dysplastic nevus) in an African-American girl.

BACKGROUND: Reed's nevi are distinguished from Sptiz tumors by their significant melanogenesis and growth pattern. They may be confused with melanoma on clinical and histologic grounds. CASE REPORT: An unusual case in which multiple agminated Reed's nevi mimicked acral lentiginous malignant melanoma in an African-American girl is presented. A critical review of the literature is presented to assist in the diagnosis. CONCLUSIONS: Awareness of this entity and of its possible clinical presentations and judicious application of conventional hematoxylin-eosin microscopic criteria remain the most useful methods to bring the correct diagnosis in most instances. Mutilating or excessive surgery may be avoided for most cases of pigmented spindle and epithelioid cell nevus.

Plantar malignant melanoma in a white Caucasian population.

Fifty-one white Caucasian patients from the west of Scotland, with stage I primary malignant melanoma arising on the plantar surface were studied. Subungual lesions were excluded from the study. Clinical and pathological features were related to survival, and compared with a group of 239 cases of clinical stage 1 melanoma of the lower limb, excluding the foot, collected in the same geographical area over the same period of time (1979-84). The average age of patients with plantar melanoma was 67 years and was significantly older than those with leg melanomas, in whom the mean age was 53 years. Twenty patients with plantar lesions had superficial spreading melanomas, 27 had acral lentiginous melanomas, and four had nodular lesions. The female:male ratio was 3:2 which was significantly different from the 7:1 female:male ratio for leg lesions. Plantar melanomas were more commonly ulcerated (57%) than were melanomas on the leg (29%) [P < 0.001]. There was no significant difference between the mean thickness of melanomas on the plantar surface and those on the leg. Nine (17%) of the patients with plantar melanomas gave a clinical history of pre-existing naevus and in 27% there was pathological evidence of a pre-existing naevus. Disease-free survival at 5 years for the population with plantar melanomas was 82, 51 and 0%, respectively, for melanomas 0-1.49, 1.5-3.49 and over 3.5 mm in thickness. This compares with 95, 71 and 46%, respectively, for leg lesions. In each thickness category patients with leg melanomas have a significantly better survival.(ABSTRACT TRUNCATED AT 250 WORDS)

Plantar melanoma: is the incidence of melanoma of the sole of the foot really higher in blacks than whites?

The overall incidence of malignant melanoma in black populations is considerably lower than that in whites. There have been repeated suggestions in the literature that black persons may have an increased incidence of melanoma of the sole, relative to whites, because among blacks with melanoma there is a high proportion with tumors of the sole of the foot. Whether this observed difference in site distribution represents a difference in incidence rates has never been demonstrated. Data on cancer incidence from 2 areas, western Washington State (1974-1983) and metropolitan Atlanta (1975-1984), were analyzed to examine this question. The annual area- and age-adjusted incidence of plantar melanoma was 1.7 per million per year for blacks and 2.0 per million per year for whites (relative risk for blacks as compared with whites = 0.88, 95% confidence interval = 0.36-2.11). These data argue that in North America there is little difference between blacks and whites in the incidence of plantar melanoma, and that the well known proportional difference appears to be due instead to the decreased incidence in blacks of melanoma on skin surfaces other than the soles of the feet.
