Hepatitis C awareness among adolescents in the Alpes-Maritimes area of France.
(41/124)
OBJECTIVES: Certain practices with a potential risk of hepatitis C virus (HCV) transmission begin early, during adolescence. In 2004, primary prevention interventions targeting adolescents aged 13-17 years attending school in the Alpes-Maritimes region of France were conducted by the "Reseau Hepatite C Ville Hopital Cote d'Azur". The aim of this study was to assess the adolescents' knowledge about HCV and to evaluate the impact of such interventions. METHODS: A random sample of secondary state schools in the Alpes-Maritimes was invited to participate in the study. Before and after presenting a slide show about HCV in the selected classrooms, the investigators asked the students to complete an anonymous self-administered questionnaire designed to assess their knowledge about HCV infection. RESULTS: The intervention concerned a study population of 2,946 students, mean age 14.4 +/- 2.5 years. Before the interventions, 21% had good knowledge of HCV infection and 24% had good know-ledge of disease contagion. These percentages increased significantly after the interventions to 95% and 84% respectively. Knowledge improvement was more significant among high school students and among students whose parents had an employment. CONCLUSIONS: Adolescents are poorly informed about HCV infection. The present intervention enabled significant improvement in their knowledge about the infection and disease contagion, independently of gender, age and geographical area. (+info)
Traceability of extensively produced Iberian pigs using visual and electronic identification devices from farm to slaughter.
(42/124)
A total of 351 Iberian pigs with equal numbers of both sexes from 2 commercial farms were used to study the ability of various identification devices to guarantee the traceability required for labeled meat products from Iberian pigs reared under extensive production conditions in Spain. The performance of tattoos, visual ear tags, electronic ear tags, and i.p.-injected transponders of half duplex and full duplex technologies were compared during a production cycle from nursery to slaughter at 15 mo of age (156 +/- 3 kg of BW). No major health reactions to any of the identification methods were detected. Results showed that tattooing was not an adequate identification procedure due to reading difficulties as a consequence of dark skin, soiled appearance, and figure deformation. Ear tag losses and failures were affected by fencing type and increased in one of the farms (20.4 and 15.7% for losses and failures, respectively; P < 0.05) as a consequence of using barbed-wire fences. Ear tag losses decreased when fences changed to stone blocks at 365 d of age. Visual and electronic ear tag losses during transport and slaughter were low (3.7% for visual and 3.1% for electronic tag). Results of injectable transponders during the growing-fattening period were variable and were more readable for the half duplex than for the full duplex i.p. transponders (92.0 vs. 68.7% +/- 1.5; P < 0.05). Handheld transceivers worked properly under extensive conditions, although the body size and skin characteristics of the Iberian breed might limit the performance of reading devices, and the use of transceivers with longer reading distances is recommended. The main problem observed with i.p. transponders was their low recovery rate at slaughter due to the lack of adherence of the transponders to the omentum. (+info)
Awareness of the risk of endocarditis associated with tattooing and body piercing among patients with congenital heart disease and paediatric cardiologists in the United Kingdom.
(43/124)
Body art in the form of tattoos and piercing has become increasingly popular amongst children and teenagers, and is nowadays more socially acceptable despite media reports citing tissue destruction and death. Our study explored the awareness and experience of patients with congenital heart disease, and of cardiologists and professionals responsible for their care. (+info)
A survey of hepatitis B and C prevalence amongst the homeless community of Prague.
(44/124)
BACKGROUND: Viral hepatitis B (VHB) and C (VHC) are a major health concern worldwide, with 170 million people chronically infected and at risk of liver cancer, cirrhosis or liver failure. Since no vaccination is available against VHC it is important to understand how to prevent future infection. The modes of transmission include intravenous drug use (IDU), blood products, tattooing and, to a lesser extent, sexual intercourse. Homelessness is a risk factor of VHB and VHC because of the environments and behaviours associated with homeless communities such as poor hygiene, nutrition and high levels of IDU. The aim of this project was to determine the prevalence of VHB and VHC and its risk factors amongst homeless community of Prague, Czech Republic. PATIENTS AND METHODS: Ninety-eight individuals of the Prague homeless community were interviewed and tested for VHB and VHC infection markers. RESULTS: The prevalence of both VHB and VHC was 26.5%. The major risk factors in this population were past and present IDU, young age and sharing the paraphernalia used by intravenous drug users (e.g. spoons, foils and filters). CONCLUSION: With the exception of age, all these risk factors could all be targeted in order to combat the major public health concern that VHB and VHC poses to the homeless community of Prague.

The value of ultrasound-guided tattooing localization of nonpalpable breast lesions.
(45/124)
OBJECTIVE: To investigate the value of ultrasound-guided tattooing localization (US-tattoo) using a charcoal suspension for breast lesions. MATERIALS AND METHODS: One hundred sixty-four nonpalpable breast lesions in 134 patients (mean age 47 years; range 30-74 years) were marked with a charcoal suspension under US guidance. The medical records associated with the US-tattoo, the pathology results and the follow-up US results were reviewed. RESULTS: The average size of the localized lesions was 1.0 cm. The procedure time was < 5 minutes (range, 2-10 minutes) per lesion. The US-tattoo was well tolerated in all cases. The only technical difficulty encountered was a needle tip blockage caused by a large charcoal particle (4.9%). The surgeon easily identified the tattoo with the exception one case. In addition, surgery could be safely delayed from one to 57 days after the making US-tattoo. The pathology result was benign in 108 cases, borderline in five, and malignant in 51. The excised specimen was < 4 cm in 76.6% (82/107) of the benign cases (mean; 2.7 cm). The pathologist could identify the mass around the tattoo and was able to make a specific diagnosis in 81.3% (87/107) of benign lesions. The only complication encountered was residual charcoal marking along the incision scar (3.6%). All follow-up US documented the removal of the lesions. CONCLUSION: An US-tattoo for nonpalpable breast lesions is a very simple and accurate method that can help surgeons design and schedule an open biopsy. (+info)
Profile of lifetime methamphetamine use among homeless adults in Los Angeles.
(46/124)
Although the dramatic rise of methamphetamine use in the general population has been well-documented, little is known about methamphetamine use in the homeless population. This study examines self-reported methamphetamine use and its correlates among a sample of 664 urban homeless adults in Los Angeles. Over one-quarter of the overall sample, and 60% of whites, disclosed lifetime methamphetamine use. Less than 10% of African-Americans reported ever using methamphetamine. Approximately one-tenth of respondents reported current methamphetamine use; almost 90% of current users shared straws to snort methamphetamine and half used it daily. Logistic regression analysis in younger (18-39) and older (40+) respondents revealed that white ethnicity, polydrug use and binge drinking were independently associated with lifetime methamphetamine use, regardless of age. Injection drug use (IDU) was also an important correlate of methamphetamine use for older African-Americans. IDU was not important for the younger group. Findings suggest that there is need for greater surveillance of methamphetamine use among homeless whites and Hispanics, and methamphetamine-use prevention and reduction targeted to younger, polydrug-using, alcohol-binging homeless adults.

A cultural psychiatric study on tattoos of young Korean males.
(47/124)
In 2, 178 tattooed male conscripts in ages of 19-24 years, the most frequent tattoo was a heart mark or a mark of heart and arrow. The Chinese characters which mean "one mind," eagles, dragons, some of 12 zodiacal animals, flowers, and flowers and butterflies or birds were also frequent. The ten Korean symbols of long life and symbols which have been traditionally believed as having evil-repelling powers, for example, blue dragon or white tiger were also found. The frequency of images were different between the provinces with different historical and cultural backgrounds. Data was obtained through interviews with 781 tattooed males. Analysis of the data revealed the following. The prevalence of tattooing was 5.6%. The most prevailing motivation to having tattoos was a contemporary group craze or fashion. Of the 781 tattooed men, 62% had tattoos on their forearms, 34.2% had self-injured scars on their bodies, and 18.6% had criminal convictions. The results of MMPI showed high scores in items of psychopathic deviate and schizophrenia. This suggests that those with tattoos were impulsive, hostile and were prone to delinquent behavior. These results indicate that selection of the image to be tattooed is heavily influenced by inner needs and the cultural background of individuals. (+info)
Technical note: Evaluation of the official identification system for pigs for sale in New South Wales.
(48/124)
A study was undertaken at 2 saleyard (1 domestic, DS, and 1 export, ES) and 2 abattoir (1 domestic, DA, and 1 export, EA) locations in New South Wales, Australia, to assess the compliance (presence) and readability of body tattoos used to identify individual pigs presented for sale or slaughter. Each location was visited on 3 trading or slaughter days, and tattoo presence and readability of porkers (25 to 60 kg of BW), baconers (60 to 90 kg of BW), backfatters (>90 kg of BW but not for breeding), and breeders were recorded. A total of 4,655 pigs were inspected, including 158 DS, 1,599 ES, 1,257 DA, and 1,641 EA. Tattoo performance at the saleyards was influenced by producer (P < 0.05). Average brand presence at the DS (93.0%) did not differ (P = 0.28) from ES (74.2%). Tattoo compliance ranged from 88.3 to 100% of pigs across pig classes (P > 0.05) at DS. At the ES, tattoo compliance among baconers, backfatters, and breeding stock ranged from 82.4 to 88.3% and was greater (P < 0.05) than that of porkers (70.3%). Average readability was 85.4% at ES and 77.6% at DS (P > 0.05). Tattoo compliance differed (P < 0.05) between abattoirs (98.7% at DA and 92.6% at EA). Readability was greater (P < 0.05) at the EA (80.1%) than at the DA (72.0%). Final performance, as readable brands among animals sold or slaughtered, of the official tattoo system was similar between locations and ranged from 63 to 74%. Our results suggest that current compliance and readability of tattoos would compromise traceback to the farm of origin in the event of an emergency animal disease outbreak. Education activities on legislation requirements and tattoo procedure would likely increase compliance and performance of the system. (+info)
