Scabies and Pediculosis in Penitentiary Institutions in Poland-A Study of Ectoparasitoses in Confinement Conditions

Burden of scabies in a Ghanaian penitentiary

BACKGROUND

There is a dearth of information concerning the epidemiology of human scabies in prisons. Therefore, we aimed to assess the burden of scabies and ascertain if prevalence was high enough to warrant mass drug administration (MDA) with ivermectin in a medium security prison in central Ghana.

METHODS

We conducted a cross-sectional study in December 2022 and recruited inmates at the Kumasi central prison in Ghana. Medical history and demographic information was collected using a REDCap questionnaire. A standardised skin examination of exposed regions of the body was performed on all participants and scabies was diagnosed based on the criteria of the International Alliance for the Control of Scabies (IACS).

RESULTS

Of the 559 participants, 19 (3.4%) were female. The median (IQR) age was 36 (33-40) years. There were 368 cases (65.8%) of scabies which was mostly located on the hands, fingers and finger webs. No female inmate had scabies. Scabies severity was predominantly mild (63.3%) or moderate (30.7%). Among males, the median (IQR) number of persons per cell was 115 (56-118) and 7 (7-8) for female prisoners. 79.2% of 96 individuals previously treated in the preceding two months still demonstrated skin manifestations of scabies. Impetigo was found in 12.9% of participants. Seventeen percent of participants with scabies had impetigo compared to 5.8% in individuals without scabies [RR 2.9 (95% CI 1.6-5.5)].

CONCLUSION

A very high proportion of inmates suffered from scabies in the prison. MDA with ivermectin and health education are needed to reduce the burden of scabies in the prison. Its implementation and effectiveness should be studied.

Resurgence of scabies in Italy: The new life of an old disease

Scabies, an old parasitic disease with a worldwide presence, has witnessed a recent resurgence in many parts of the world even in the light of the COVID-19 pandemic. We conducted a study on this resurgence in the Italian province of Messina, Sicily, evaluating the general features of affected people to better understand the possible modes of transmission. Specifically, we considered all the scabies notifications made in the period 2003-2022. Then, we focused on those cases occurred in the three-years period 2020-2022 carrying out an active surveillance by calling patients and asking them questions about their recent habits and movements and their consequent chances of contracting the disease. In total, 935 cases of scabies were reported from 2003 to 2022, with a remarkable increase between 2020 and 2022, when 288 cases were reported. Of these patients, we were able to reach by phone 240 (83.3 %) and interview them. Students were the most affected group (24.1 %), followed by retirees (21.0 %) and healthcare workers (13.2 %). Unfortunately, concerning the possible mode of transmission, more than half (58.5 %) of patients were not able to understand the real source of their infection. When known, the most common ways of transmission were a familiar origin (10.7 %) followed by causes linked to health environments (nursing home stays and hospital admissions). Moreover, 66.9 % of all the reported cases were part of an outbreak. Larger outbreaks occurred in healthcare facilities for more than half of the cases (69.4 %), the majority of which (88.9 %) were in nursing homes. Our research confirms the resurgence of scabies in our territory similar to trends in other European countries. Some critical factors, including the COVID-19 pandemic, probably played a key role in influencing this epidemiological trend and showed the importance of always monitoring the epidemiology of all notifiable diseases to enable prompt action by competent authorities to limit their spread to the community.

Global prevalence and predictors of scabies among prisoners: systematic review and meta-analysis

INTRODUCTION

Scabies is a widespread issue in prisons due to overcrowded living conditions and limited healthcare resources. A recent study published in the Journal of Infection and Public Health discovered that the prevalence of scabies varies greatly among prisoners in different regions and facilities. This review aimed to determine the global prevalence and predictors of scabies among prisoners by conducting a systematic review and meta-analysis.

METHODS

We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis checklist to report the findings of our systematic review and meta-analysis. Relevant databases including PubMed, Cochrane Library, ScienceDirect, and other grey literature databases were used to search and retrieve articles. The study included both published and unpublished research written in English languages for studies reporting the prevalence of human scabies among prisoners. This review has been registered on PROSPERO. The heterogeneity of the data was evaluated using the I2 statistic. A meta-analysis was conducted using STATA 17 software, with a 95% confidence interval. The researchers also conducted publication bias and sensitivity analysis.

RESULTS

The review included 7 studies involving 1, 309,323 prisoners. All included studies involved cross-sectional study design. The prevalence of scabies among prisoners ranges from 0.72% in Italy to 41.01% in Cameroon. The global pooled prevalence of human scabies among prisoners was found to be 6.57% (95% CI; 2.16-19.94). According to subgroup analysis, the overall prevalence of scabies among African prisoners was 19.55% (95% CI; 9.44-40.45), while the prevalence among prisoners outside of Africa was 1.57% (95% CI; 0.77-3.19). The length of time spent in prison, sharing of clothing or beds, and hygiene practices were found to be factors that were significantly associated with the likelihood of prisoners developing human scabies.

CONCLUSION

The overall prevalence of human scabies is high among prisoners worldwide. Prisoners who spent more time in prison shared clothing or beds, and had poor hygiene practices were more likely to develop human scabies. Thus, efforts should be made by policymakers and program administrators to decrease the prevalence of scabies in prisons. The protocol for this systematic review and meta-analysis was registered in the International Prospective Register of Systematic Reviews with registration number CRD42024516064.

Pediculosis capitis risk factors in schoolchildren: hair thickness and hair length

The human head lice is a cosmopolitan ectoparasite that causes pediculosis. The main way of spreading lice is through direct head-to-head contact. It is popular knowledge that some individuals are more susceptible to contracting head lice than others. Reports of individuals who have never been affected by the disease are common, even living in the same environment and under the same conditions as people who regularly have lice infestations. Previous research has been carried out on the risk of this infection associated with different human factors like gender or age. However, studies on the influence of the individual hair characteristics are scarce. The objective of the study was to analyze the pediculosis risk using geographical location, gender, age and individual hair characteristics as variables. Pediculosis was diagnosed through the detection of living lice in the hair. This cross-sectional school-based epidemiological study was conducted in 310 schoolchildren aged 1 to 13 years of schools in 4 municipalities situated in the State of Paraná, Brazil. The prevalence of head louse infection in primary school students was 49.35 %. The Odds Ratio of presence of pediculosis (OR) was estimated using multivariate logistic regression analysis. The results obtained indicate that hair length and thickness increase the risk of infection. Furthermore, the inclusion of hair color, hair shape, kind of hair-scale as covariates increases the risk of pediculosis, indicating that these variables partly explain this susceptibility and that pediculosis is independent of gender. A smaller hair diameter may favor insect fixation to the hair in the nymphal phases. These results may explain why girls are a greater risk as they let their hair grow for cultural reasons, i.e., being of female gender is an agglutinating variable. The conclusions drawn may explain the discrepancies obtained in previous analyses.

Scabies prevalence and its associated factors among prisoners in southern Ethiopia: An institution-based analytical cross-sectional study

BACKGROUND

Scabies is an ectoparasitic infestation that can easily spread during close human contact and in overcrowded areas such as prisons and public places where sanitation is a problem. Globally, as many as 300 million people are infested with scabies each year. Within Ethiopia, its burden in institutions like prisons is not well-studied. As a consequence, we sought to estimate the prevalence of scabies and also identify factors associated with it among prison inmates in southern Ethiopia.

METHODS

An institution-based analytical cross-sectional study design was employed. We used, a simple random sampling technique to select 422 prisoners. A pretested-structured questionnaire was used to collect the necessary information. EpiData version 4.2.0.0 and Statistical Packages for Social Science version 25 software were used for data entry and analysis respectively. Both descriptive and inferential statistics were computed. The model fitness was checked using the Hosmer-Lemeshow and omnibus tests. The association between the independent and outcome variables was presented in the form of a table showing the crude odds ratio and adjusted odds ratio (AOR) along with their 95% confidence interval (CI). The level of statistical significance was declared at P.value ≤ 0.05.

RESULTS

A total of 418 prisoners were interviewed, yielding a 99.1% response rate. The age of the participants ranged from 17 to 60 years. As many as 381 (91.1%) participants were male. The prevalence of scabies was found to be 8.9%. A history of sexual contact in the past two months, before imprisonment (AOR: 9.92 (95% CI 3.07, 32.02), P <0.001), a period of stay less than two months duration in the prison (AOR: 4.54 (95% CI 1.51, 13.54), P = 0.007), poor ventilation (AOR: 3.36 (95% CI 1.07, 10.58), P = 0.038), lack of hygiene soap (AOR: 5.53 (95% CI 1.45, 21.17), P = 0.012), and sharing clothes among each other (AOR: 3.81 (95% CI (1.09, 13.29), P = 0.036) were factors independently associated with a scabies infestation.

CONCLUSION

In this study, we found the prevalence of scabies was high among prison inmates in Wolaita Zone prison. Furthermore, scabies infestations were associated with a previous history of sexual contact, poorly ventilated rooms, lack of hygiene soaps for washing, and sharing clothes amongst the inmates. Prison administrations should be encouraged to improve sanitary and screening and isolation of prisoners during imprisonment.

[PREVALENCE AND ASSOCIATED FACTORS OF HUMAN SCABIES IN PRISONS IN DOSSO, NIGER]

Background

Scabies is a contagious, pruritic, cosmopolitan dermatosis, widespread especially in human communities, due to parasitism by a mite Sarcoptes scabiei var hominis A lack of hygiene and overcrowding inside the houses are favourable factors. The aim of our study was to determine the prevalence and factors associated with the occurrence of human scabies in the prison environment in Dosso (Niger).

Materials and methods

Prospective descriptive cross-sectional study conducted in November 2022 in the civil prison of Dosso on authorization of the prison administration. The collected data were sociodemographic characteristics, personal history of pruritus and its characteristics, risk factors related to hygiene and conditions of incarceration, examination performed by a dermatologist to look for clinical signs of scabies. The diagnosis was retained in any inmate presenting one or more elements at the interrogation and at the physical examination.

Results

Out of a total of 352 inmates, 43 (38 males and 5 females) had scabies, a prevalence of 12%. The average age was 33 with extremes of 18 and 62 years. Of the scabies patients, 9% reported a history of intense, sleepless pruritus prior to incarceration. Most of the inmates, 86%, were in cells with more than 20 inmates. Among those with scabies, 42% showered twice a day, 81% changed clothes after showering and 74% used soap regularly for washing. The topography of the lesions was external genitalia (37%), buttocks (21%), inner thighs (16%), interdigital spaces (9%), elbows (9%) and wrists (7%). The inmates were informed about the disease, treatment information was explained to them, and they attended a session on hygiene promotion. All cases of scabies detected were prescribed a local treatment based on benzyl benzoate lotion 25%.

Discussion/conclusion

Human scabies is common in the prison environment in Dosso. Too often, scabies goes undetected and is confused with other pruritic dermatoses, such as eczema or atopic dermatitis. Prison medical staff should be trained in scabies in order to prevent scabies outbreaks. The authorities in the region should make the improvement of hygiene and detention conditions in prisons their priority.

Head Lice Infestation in Schoolchildren, in Poland-Is There a Chance for Change?

Pediculosis capitis is a current and neglected health issue worldwide. The lack of screening programs contributes to the marginalization of the problem and delays therapeutic measures. Our study aimed to analyze the occurrence of this parasitosis in primary schools in Poland and to determine factors contributing to the persistence of its foci. The research tools were two questionnaires: one for primary school children and the other for school managers. While children answered questions about the epidemiology of pediculosis capitis and expressed their opinion on the hygienic condition of infested persons, the school directors were asked about the occurrence of head lice in schools, preventive measures, and institutions supporting schools in combating the infestation. The survey covered the period 2014–2018. Pediculosis capitis was reported in 87.5% of the schools. The greatest number of cases was reported in the group of 6–9 year-olds (68%). Among 4970 children, 16.7% had no knowledge of head lice; however, 57.1% wanted to increase their awareness of the problem. Campaigns on lice were conducted mainly as a result of emerging pediculosis capitis cases, and most schools could not rely on institutional support. Screening programs and preventive educational campaigns should be part of pediculosis capitis control in Poland.

The Incidence of Scabies and Head Lice and Their Associated Risk Factors among Displaced People in Cham Mishko Camp, Zakho City, Duhok Province, Iraq

This study was conducted to estimate the incidence and the effects of associated risk factors of scabies and head lice on displaced people in Cham Mishko camp, Zakho city, Duhok Province, Iraq. The study included 1300 internally displaced people (IDPs) who visited the dermatology clinic and health care center in Cham Mishko camp from January 2018 to December 2019. Participants' bio-information was collected on special questionnaire form after receiving permission from the camp's health authorities and verbal consent from the participants. Monthly weather data were collected from Duhok Directorate of Meteorology and Seismology. The total rate of ectoparasites was 81.2% (45% for scabies and 36.2% for head lice). Ages from 1-10, 21-30, and 31-40 years showed the highest rates with scabies (48.1%, 46.7% and 46.1%, respectively), while the highest rates of head pediculosis were at ages from 1-10 and 11-20 years (40% and 36.6%, respectively). Scabies rate was slightly higher in males than females (46.6% vs. 43.4%), while the rate of head pediculosis was significantly higher in females than males (58.2% vs. 13.9%). Families with more than ten people showed the highest rates of scabies and head pediculosis (49.5% and 74.5%). Scabies was more common in cold months than in summer while head pediculosis was more common in hot months. The number of scabies and head pediculosis cases increased by 123 and 85 cases, respectively, in 2019. It is inferred that the effects of scabies and head pediculosis in IDPs will be considerable, with a higher carriage rate than other studies in Iraq.

Work Engagement among Prison Officers. The Role of Individual and Organizational Factors in the Polish and Indonesian Penitentiary Systems

The literature on work engagement among prison officers (POs) remains rather scarce, and there are no analyses on the factors determining this phenomenon. The current study aimed to examine the relationships between work engagement, subjective well-being, coping strategies, and organizational factors utilizing the Utrecht Work Engagement Scale (UWES-9), the Coping Orientation to Problems Experienced (COPE), and Cantril’s Ladder of Health Scale (CLHS), and involving 312 POs from Poland and 467 POs from Indonesia. Results showed a statistically significant relationship between active coping and work engagement in both groups. Subjective well-being was moderately related to work engagement among Polish POs. Mean work engagement and subjective well-being scores were higher among Indonesian POs. The analyses showed a significant indirect effect of subjective well-being for the relationship between penitentiary unit type, active coping, as well as avoidant behaviors and work engagement in the Polish group. Closed prison officers more often declared higher subjective well-being. Work engagement is a complex psychological phenomenon. There exists a justified need for the analyses to consider personal determinants (e.g., coping strategies) as well as organizational factors related to the POs’ work environment. The literature presents a broad picture of the benefits of studying this phenomenon.
