Prevalence of latent tuberculosis, syphilis, hepatitis B and C among asylum seekers in Malta

BACKGROUND In the last few years, Malta has witnessed increasing immigration flows from the Libyan coasts. Public health policies are focused on screening migrants for tuberculosis, whereas no systematic actions against STIs are implemented. The aim of this study is to define the epidemiological profile of asylum seekers in Malta as regards syphilis, hepatitis B, C and latent tuberculosis, thus supporting screening policies. METHODS Five hundred migrants living in open centres were screened between December 2010 and June 2011. RESULTS 83.2% of people was from Somalia, 81.2% males, average age 26.5 years. The tuberculin skin test (TST) was positive in 225 migrants (45%). Latent syphilis was diagnosed in 11 migrants, hepatitis C in 3 and 31 migrants were HBsAg positive. CONCLUSION Systematic screening for asymptomatic migrants in Malta is not recommended for hepatitis C and syphilis, given the low prevalence observed. On the contrary, it should be considered for hepatitis B. TST could be indicated as the first step of a two step screening for migrants from countries with high TB incidence. Efficacy and cost-effectiveness could be achieved by further targeting screening to specific subgroups at higher risk of reactivation, such as people living with HIV and subjects affected by chronic diseases.

Microbiological evaluation of bacterial and mycotic seal in implant systems with different implant-abutment interfaces and closing torque values

Objective:The aim of this study was to evaluate the possible leakage of 3 species of bacteria (Streptococcus sanguinis, Fusobacterium nucleatum, and Actinomyces odontolyticus) and of Candida albicans and Candida glabrata in osseointegrated implants with different implant-abutment interface (IAI) geometry. Materials and Methods:Two groups of implants, (1) implant-abutment unit with a tube-in-tube interface and (2) implant-abutment unit with a flat-to-flat interface closed with different torque values, were compared in the study. In the first phase, the implants were assembled and cultured in vitro for 7 days. The implants and abutments were disconnected and samples were taken and cultured. In the second phase, the internal part of each implant was inoculated with 0.1 µL of microbial broth and then connected to the respective abutments. Afterward, medium samples were taken and cultured. Results:The group 1 implants were more resistant to colonization than those of group 2 (P < 0.05). The intragroup difference was significant between the implant-abutment units assembled with the recommended torque values and those with lower torque values (P < 0.01) for both the groups. Conclusion:IAI geometry influences both bacterial and yeast colonization inside the implants as well as the torque value used to connect abutments to implants.

Epidemiology of Skin Disorders in Ethiopian Children and Adolescents: An Analysis of Records from the Italian Dermatological Centre, Mekelle, Tigray, Ethiopia, 2005 to 2009

Abstract:  Skin disorders are an important problem in children living in developing countries, but only a few epidemiologic investigations on pediatric dermatoses are available in the literature. Our study is an analysis of the range and frequency of skin diseases presenting to the Italian Dermatological Center in a pediatric Ethiopian population. A retrospective analysis was performed on 17,967 medical records of children aged 0 to 18 years attending the Italian Dermatological Centre in Mekele (Ethiopia) from January 2005 to December 2009. Infections and infestations accounted for 47% of the disorders seen; fungal infections were the most common (44.1%), followed by bacterial and parasitic diseases. Dermatitis constituted the second most common diagnostic category (24.7%) of the disorders seen, and contact dermatitis was the most common diagnosis (48.8%). Pigmentary disorders and disorders of skin appendages were more common in girls, whereas fungal and parasitic infections were more common in boys. Bacterial and parasitic infections were more common in children younger than 1 year old, fungal infections in those aged 1 to 5.9, and disorders of skin appendages and pigmentary disorders in those aged 15 to 18. These findings demonstrate that most of the disorders seen could be easily managed in clinical practice with appropriate skill development. It is crucial to ensure that training of medical students and pediatricians focuses on accurate recognition, diagnosis, and management of these common skin diseases and that families, teachers, health workers, and nurses be educated about the most common signs of prevalent skin diseases to help facilitate appropriate care.

Clinical Practice and Knowledge in Caring: Breastfeeding Ties and the Impact on the Health of Latin-American Minor Migrants

In the context of the project “Clinical and social evaluation of medical practices in the treatment of infectious diseases in pediatrics for children of vulnerable population” carried out in 2013 by a multidisciplinary team at the National Institute for Health, Migration and Poverty (NIHMP) in Rome, a study in medical anthropology on the incorporation of illnesses that mothers feel they transmit to their children through breastfeeding was conducted. The results of the anthropological study, that targeted 34 children and adolescents from the age of 3 to the age of 17, all immigrants from Latin America residing in Italy, show that some forms of suffering in minors are described by women as being connected to factors such as susto (“fright”), coraje, muina, enojo (“anger”) and mal de ojo (“evil eye”), and are in relation to a specific cultural frame. It is clear that barriers that prevent the access to the healthcare system must be removed, barriers that are accentuated by linguistic and cultural incomprehension, through adequate multidisciplinary healthcare settings such as the one we are presenting, composed of a medical doctor, an anthropologist and a cultural mediator.

Evaluation of eye movements pattern during reading process in patients with glaucoma: a microperimeter study

Purpose To assess eye movements pattern during reading process in patients with primary open-angle glaucoma (POAG) using a microperimeter. Methods Thirty-two patients with POAG at early and moderate stage, according to Glaucoma Staging System 2, and 34 healthy age- and sex-matched subjects were included in the study. Reading speed and accuracy were previously evaluated with specific tests adjusted for age. In addition, all participants performed a reading test with Microperimeter Nidek MP1. Ocular movements during the reading process were recorded and values of maximum and minimum eye movements along the horizontal (Xmax and Xmin) and vertical (Ymax and Ymin) axis and mean ocular movement speed were provided by the MP1. Results There were significant differences between patients with and without POAG in terms of Xmax and Ymax eye movement values (4.75 ± 2.57 versus 3.38 ± 0.67, p = 0.003; and 4.39 ± 1.43 versus 3.34 ± 0.52, p<0.001, respectively). These differences were significant even comparing only stage 1 patients to controls. There were no significant differences in Xmin and Ymin values and mean ocular movement speed between the 2 groups. Conclusions The study showed significant differences in eye movements pattern in patients with POAG during the reading test performed with the MP1 when compared to the control group. These alterations may be partly the consequence of the neurodegenerative process of the central visual pathway in glaucoma.

Unusual case of B cell lymphoma after immunosuppressive treatment for psoriasis.

Lymphomas may be induced by the systemic immunosuppressive therapies used to treat psoriasis, such as ciclosporin, methotrexate and tumour necrosis factor (TNF)-α blockers. The biologic agents currently used in psoriasis include alefacept, efalizumab, and the TNF-α antagonists etanercept, infliximab, and adalimumab. Infections and cancer are the main possible consequences of intended or unexpected immunosuppression. We report a 59-year-old man with a history of severe psoriasis vulgaris treated with traditional immunosuppressant drugs followed by anti-TNF-α therapy; the patient was firstly hospitalized for an acute cholestatic toxic hepatitis, which we supposed to be related to adalimumab. The first liver biopsy showed active disease with severe hepatocellular damage caused by heavy lymphocytes infiltrate in portal tracts at in the interface with a not conclusive diagnosis of lymphoproliferative disease. The correct diagnosis of T cell/histiocyte- rich large B cell lymphoma (T/HRBCL) was only reached through a gastric biopsy and a second liver biopsy. T/HRBCL is an uncommon morphologic variant of diffuse large B-cell lymphoma not described until now in psoriatic patients receiving immunosuppressive biologic agents. In psoriatic patients, treated with biologic immunosuppressive agents, the suspect of abdominal lymphoma should always be included as differential diagnosis. Abdominal ultrasound evaluation need therefore to be included in the pre-treatment screening as in the follow-up surveillance.

An immunocompetent migrant presenting with neurosyphilis with an unusual unilateral papillitis: a case report

Unilateral papillitis caused by Treponema pallidum was found in an immunocompetent homosexual patient with severe vision loss who had received previous antibiotics treatment. Syphilis-related ocular manifestation is more common in the early stages of the disease and it can be associated with a central nervous system localization. In this patient, neurosyphilis was diagnosed on the basis of clinical and laboratory findings. Optical examination revealed unilateral papillitis in the left eye and no relative afferent pupillary defects. The patient underwent visual field examinations with conventional perimetry using the 30-2 program of the Humphrey Visual Field Analyzer, which indicated a blind spot enlargement in the left eye. Optical coherence tomography, visual evoked potentials (VEP), and fluorescein angiograms revealed inflammation of the optic nerve head with edematous and blurred margins. A reactive T. pallidum hemagglutination assay with low rapid plasma reagin (RPR) serum titer was performed; an HIV antibody test and MRI of the orbits and head with contrast gave negative results. Resolution of the ocular inflammation after intravenous penicillin treatment was obtained. The reported case illustrates the importance of early recognition of this treatable disease. The rise of syphilis, especially in urban areas, necessitates a high level of suspicion when dealing with patients with intraocular inflammation of unknown origin. Lues serology should be incorporated into routine laboratory diagnostics to aid in the detection of such cases. Considering the re-emergence of syphilis, screening of migrants from countries with high syphilis seroprevalences should be recommended.

The variation in the health status of immigrants and Italians during the global crisis and the role of socioeconomic factors

BackgroundThe effects of the recent global economic and financial crisis especially affected the most vulnerable social groups. Objective of the study was to investigate variation of self-perceived health status in Italians and immigrants during the economic global crisis, focusing on demographic and socioeconomic factors.MethodsThrough a cross-sectional design we analyzed the national sample of multipurpose surveys “Health conditions and use of health services” (2005 and 2013) conducted by the Italian National Institute of Statistics (ISTAT). Physical Component Summary (PCS) and Mental Component Summary (MCS) scores, derived from SF-12 questionnaire, were assumed as study outcome, dichotomizing variables distribution at 1st quartile. Prevalence rate ratios (PRR) were estimated through log-binomial regression models, stratified by citizenship and gender, evaluating the association between PCS and MCS with surveys’ year, adjusting for age, educational level, employment status, self-perceived economic resources, smoking habits, body mass index.ResultsFrom 2005 to 2013 the proportion of people not employed or reporting scarce/insufficient economic resources increased, especially among men, in particular immigrants. Compared with 2005 we observed in 2013 among Italians a significant lower probability of worse PCS (PRR = 0.96 both for males and females), while no differences were observed among immigrants; a higher probability of worse MCS was observed, particularly among men (Italians: PRR = 1.26;95%CI:1.22–1.29; immigrants: PRR = 1.19;95%CI:1.03–1.38). Self-perceived scarce/insufficient economic resources were strongly and significantly associated with worse PCS and MCS for all subgroups. Lower educational level was strongly associated with worse PCS in Italians and slightly associated with worse MCS for all subgroups. Being not employed was associated with worse health status, especially mental health among men.ConclusionsOur findings support the hypothesis that economic global crisis could have negatively affected health status, particularly mental health, of Italians and immigrants. Furthermore, results suggest socioeconomic inequalities increase, in economic resources availability dimension. In a context of public health resources’ limitation due to financial crisis, policy decision makers and health service managers must face the challenge of equity in health.

Multidisciplinary Study on the Socio-Cultural Barriers to Breastfeeding and on the Health of Children and Adolescents Immigrated in Italy from Latin America and Europe

In the context of the project Clinical and social evaluation of medical practices in the treatment of infectious diseases in paediatrics for children of vulnerable populations carried out in 2012-2014 by a multidisciplinary team at the [name deleted to the review process] a study in medical anthropology was conducted. The research targeted 75 children and adolescents immigrated to Italy from Latin America and Europe. The study aimed at analysing the sociocultural representation of women regarding: barriers to breastfeeding, the impact of cessation or non-cessation, and the effects of breastfeeding on the psychological and physical health of infants.

Hepatitis C virus infection among non-IDU HIV-infected and uninfected men who have sex with men.

In the Mediterranean countries, hepatitis C virus infection affect nearly 45% of HIV-1 infected individuals, consistently to the high proportion of patients with a history of intravenous drug use and exposed to the two viruses by parenteral route. Even in association with HIV-infection, HCV infection is rarely transmitted through sexual intercourse due to the lower efficiency of mucosal exposure to virus than that blood-borne. Thus, the incidence and prevalence of HCV infection are far lower among the non-intravenous drug users (IDU) at risk of sexually transmitted infections (STI). Two hypotheses may be taken in account to explain the lower prevalence rates observed in our seroprevalence study. The MSMs participating to our study could have less sexual contacts with IDU-MSMs than other gay community residents in other western countries. The non-IDU MSMs recruited in this study could have a lower frequency of at-risk sexual practices for HCV then the non-IDU MSMs enrolled in other studies.
