RESUMO
The diagnosis and treatment of pelvic bone hydatidosis (BH) present substantial challenges for orthopedic surgeons, requiring collaboration with parasitologists, radiologists, pathologists, and engineers. Surgical treatment selection depends on factors such as the extent of bone loss, soft tissue management, previously applied therapies, and local colonization status. This report details the advanced management of two young patients diagnosed late with severe cystic pelvic BH, an atypical presentation due to their geographic origin and age. Following extensive diagnostic assessments, including serology and 3D imaging, the patients underwent a two-step surgical intervention. The initial surgery involved extensive debridement and the placement of a poly-methyl-methacrylate spacer, followed by a second procedure utilizing a custom-made, tri-flanged implant for definitive pelvic reconstruction. The custom implant, designed via an electron beam melting process, successfully restored hip functionality and anatomy, as evidenced by improvements in functional scores and post-operative imaging. Short-term monitoring confirmed the integration of the implant and the absence of infection recurrence, demonstrating the approach's effectiveness. These cases highlight the potential of using additive manufacturing (AM) to create patient-specific implants for managing complex hip cases and emphasize the necessity for early detection and a multidisciplinary approach in treatment planning.
RESUMO
BACKGROUND: The association of fever, focal hepatic lesions and peripheral hyper-eosinophilia (FHLH) can be observed in both infectious and non-infectious conditions. Fascioliasis, capillariasis, toxocariasis, all causes of visceral larva migrans (VLM), represent most of the former, whilst lymphomas, eosinophilic leukemias and mastocytosis belong in the non-infectious conditions. METHODS: We prospectively followed a young patient presenting with FHLH in the Tuscany region of Italy. RESULTS: The patient was subject to serological and parasitological examination in an attempt to clarify the origin of the lesions. Serologies for both Fasciola hepatica and Toxocara spp. were positive, with the latter presenting a higher index. We opted for treatment with a prolonged course of albendazole due to the serological results and being toxocariasis more frequent in our setting. The patient was then subject to radiological follow-up. The patient responded to treatment with albendazole as shown by a decrease in eosinophils, seronegativization for Toxocara spp., clinical and radiological improvement. Toxocariasis was hence considered the most likely diagnosis. CONCLUSIONS: Parasitic infections cannot be disregarded in the presence of FHLH. Differential diagnosis between these parasitic infections can be challenging due to the presence of similar clinical presentations and serological cross-reactions, and follow-up of the patient is needed to ensure optimal treatment outcomes.

BACKGROUND: The real burden of human cystic echinococcosis (CE) remains elusive, due to the peculiar characteristics of the disease and the heterogeneous and incomplete data recording of clinical cases. Furthermore, official notification systems do not collect pivotal clinical information, which would allow the comparison of different treatment outcomes, and thus circumvent the difficulty of implementing clinical trials for CE. The Italian Register of CE (RIEC) was launched in 2012 and expanded in 2014 into the European Register of CE (ERCE). The primary aim of the ERCE was to highlight the magnitude of CE underreporting, through the recording of cases that were not captured by official records. We present an overview of data collated in the ERCE and discuss its future, five years after its inception. METHODS: The ERCE database was explored on March 31st 2019; data concerning participating centres and registered cases were descriptively analysed. RESULTS: Forty-four centres from 15 countries (7 non-European) were affiliated to the ERCE. Thirty-four centres (77%) registered at least one patient; of these, 18 (53%) recorded at least one visit within the past 18 months. A total of 2097 patients were registered, 19.9% of whom were immigrants. Cyst characteristics were reported for at least one cyst at least in one visit in 1643 (78.3%) patients, and cyst staging was used by 27 centres. In total, 3386 cysts were recorded at first registration; mostly located in the liver (75.5%). Data concerning clinical management could be analysed for 920 "cyst stage-location-management" observations, showing great heterogeneity in the implementation of the stage-specific management approach recommended by the WHO. CONCLUSIONS: The ERCE achieved its goal in showing that CE is a relevant but neglected public health problem in Europe and beyond, since a proportion of patients reaching medical attention are not captured by official notification systems. The ERCE may provide a valuable starting platform to complement hospital-derived data, to obtain a better picture of the epidemiology of clinical CE, and to collect clinical data for the issue of evidence-based recommendations. The ERCE will be expanded into the International Register of CE (IRCE) and restructured aiming to overcome its current criticalities and fulfil these aims.

BACKGROUND: Cystic echinococcosis (CE) is a neglected parasitic zoonosis prioritized by the WHO for control. Several studies have investigated potential risk factors for CE through questionnaires, mostly carried out on small samples, providing contrasting results. We present the analysis of risk factor questionnaires administered to participants to a large CE prevalence study conducted in Bulgaria, Romania and Turkey. METHODS: A semi-structured questionnaire was administered to 24,687 people from rural Bulgaria, Romania and Turkey. CE cases were defined as individuals with abdominal CE cysts detected by ultrasound. Variables associated with CE at P < 0.20 in bivariate analysis were included into a multivariable logistic model, with a random effect to account for clustering at village level. Adjusted odds ratios (AOR) with 95% CI were used to describe the strength of associations. Data were weighted to reflect the relative distribution of the rural population in the study area by country, age group and sex. RESULTS: Valid records from 22,027 people were analyzed. According to the main occupation in the past 20 years, "housewife" (AOR: 3.11; 95% CI: 1.51-6.41) and "retired" (AOR: 2.88; 95% CI: 1.09-7.65) showed significantly higher odds of being infected compared to non-agricultural workers. "Having relatives with CE" (AOR: 4.18; 95% CI: 1.77-9.88) was also associated with higher odds of infection. Interestingly, dog-related and food/water-related factors were not associated with infection. CONCLUSIONS: Our results point toward infection being acquired in a "domestic" rural environment and support the view that CE should be considered more a "soil-transmitted" than a "food-borne" infection. This result helps delineating the dynamics of infection transmission and has practical implications in the design of specific studies to shed light on actual sources of infection and inform control campaigns.

Parasitäre Erkrankungen werden in Europa relativ selten diagnostiziert und behandelt. Somit sind auch klinische Besonderheiten und bildgebende Merkmale weniger bekannt. In den heutigen Zeiten von Migration und weltweiter Flüchtlingsströme ist die Kenntnis parasitärer Infektionen zunehmend von Bedeutung. Anhand von klinischen Beschreibungen der Echinokokkose, Schistosomiasis, Fasciolosis und Ascariasis wurden entsprechende Berichte in der Zeitschrift für Gastroenterologie publiziert. In der hier präsentierten Veröffentlichung werden klinische Besonderheiten und Bildgebungsmerkmale der Toxocariasis diskutiert.

RESUMO
Cystic echinococcosis (CE) is a zoonosis caused by the larval stage of the tapeworm Echinococcus granulosus. In humans, the infection induces the formation of parasitic cysts mostly in the liver and lungs, but virtually any organ can be affected. CE of the bone is one of the rarest forms of the disease, yet it is also extremely debilitating for patients and hard to manage for clinicians. Unlike abdominal CE, there is currently no expert consensus on the management of bone CE. In this study, we conducted a survey of the clinical records of seven European referral centers for the management of patients with CE and retrieved data on the clinical management of 32 patients with a diagnosis of bone CE. Our survey confirmed that the patients endured chronic debilitating disease with a high rate of complications (84%). We also found that diagnostic approaches were highly heterogeneous. Surgery was extensively used to treat these patients, as well as albendazole, occasionally combined with praziquantel or nitaxozanide. Treatment was curative only for two patients, with one requiring amputation of the involved bone. Our survey highlights the need to conduct systematic studies on bone CE, both retrospectively and prospectively.

BACKGROUND: Taenia solium and Taenia saginata are food-borne parasites of global importance. In eastern Europe only fragmented information is available on the epidemiology of these zoonotic parasites in humans and animal populations. In particular for T. solium, on-going transmission is suspected. The aim of this systematic review was to collect the available data and describe the current knowledge on the epidemiology of T. solium and T. saginata in eastern Europe. METHODS: Literature published in international databases from 1990 to 2017 was systematically reviewed. Furthermore, local sources and unpublished data from national databases were retrieved from local eastern European experts. The study area included 22 countries. RESULTS: Researchers from 18 out of the 22 countries provided data from local and unpublished sources, while no contacts could be established with researchers from Belarus, Kosovo, Malta and Ukraine. Taeniosis and human cysticercosis cases were reported in 14 and 15 out of the 22 countries, respectively. Estonia, the Former Yugoslav Republic of Macedonia, Lithuania, Moldova, Poland, Romania, Serbia, and Slovakia reported cases of porcine cysticercosis. Croatia, Czech Republic, Estonia, Former Yugoslav Republic of Macedonia, Moldova, Poland, Romania, Serbia, Slovakia, and Ukraine reported bovine cysticercosis. CONCLUSIONS: There is indication that taeniosis and cysticercosis are present across eastern Europe but information on the occurrence of T. solium and T. saginata across the region remains incomplete. Available data are scarce and species identification is in most cases absent. Given the public health impact of T. solium and the potential economic and trade implications due to T. saginata, notification of taeniosis and human cysticercosis should be implemented and surveillance and notification systems in animals should be improved.

OBJECTIVE: The aim of this study is to verify if the experience on 4 years in using minimally invasive techniques in the treatment of CE could match regarding the indications and results with the major studies on topic. METHOD: During 03.2014 - 03. 2018 period, 38 PAIR, 28 MoCaT procedures and 7 percutaneous drainages have been performed at 51 patients from 76 cases of hydatid hepatic cysts (67,1%). There were 26 men and 25 women, and the age ranged from 19 to 78. 7 patients have had 2 hydatid hepatic cysts or more and 2 procedures were performed at 3 of those patients; other 11 patients needed the second procedure during the surveillance. Results: The evolution of the patients was favorable, and the surveillance was 2 years postintervention at least. There were no major surgical adverse effects. We defined as an expected result obtaining a scar lesion or a small cavity with calcified walls (hyperechoic). Only 2 (3,9%) patients needed conversion to open surgery. The complications we have faced were represented by the cystic-biliary fistula in 15 cases (29,4%) and the re-opening of the cyst's cavity in 11 cases (21,67%). Conclusions: The percutaneous treatment of CE is safe and effective, following the correct assignation according with the cysts type. The percutaneous treatment of CE is an easier alternative to the open surgery and has lower rate of complications and relapses, and a shorter hospitalisation. Now routine, it becomes slighty the first option for invasive treatment of CE. The role of open surgery is restricted to CE with severe complications.

BACKGROUND: Cystic echinococcosis is a neglected zoonotic infection that is distributed worldwide and prioritised by WHO for control efforts. The burden of human cystic echinococcosis is poorly understood in most endemic regions, including eastern Europe. We aimed to estimate the prevalence of abdominal cystic echinococcosis in rural areas of Bulgaria, Romania, and Turkey. METHODS: We did a cross-sectional ultrasound-based survey that recruited volunteers from 50 villages in rural areas of Bulgaria, Romania, and Turkey. These villages were in provinces with annual hospital incidence of cystic echinococcosis within the mid-range for the respective countries. All people who attended a session were allowed to participate if they agreed to be screened. Abdominal ultrasound screening sessions were hosted in public community structures such as community halls, primary health-care centres, schools, and mosques. Lesions were classified using an adapted WHO classification. We reported the prevalence of abdominal cystic echinococcosis adjusted by sex and age through direct standardisation, using the country's rural population as a reference. FINDINGS: From July 1, 2014, to Aug 3, 2015, 24â693 individuals presented to screening sessions and 24â687 underwent ultrasound screening. We excluded a further six indivduals due to missing data, leaving 24â681 people in our analysis. Abdominal cystic echinococcosis was detected in 31 of 8602 people screened in Bulgaria, 35 of 7461 screened in Romania, and 53 of 8618 screened in Turkey. The age and sex adjusted prevalence of abdominal cystic echinococcosis was 0·41% (95% CI 0·29-0·58) in Bulgaria, 0·41% (0·26-0·65) in Romania, and 0·59% (0·19-1·85) in Turkey. Active cysts were found in people of all ages, including children, and in all investigated provinces. INTERPRETATION: Our results provide population-based estimates of the prevalence of abdominal cystic echinococcosis. These findings should be useful to support the planning of cost-effective interventions, supporting the WHO roadmap for cystic echinococcosis control. FUNDING: European Union Seventh Framework Programme.

Cystic echinococcosis (CE) is a zoonotic parasitic disease endemic in southern and eastern European countries. The true prevalence of CE is difficult to estimate due to the high proportion of asymptomatic carriers who never seek medical attention and to the underreporting of diagnosed cases, factors which contribute to its neglected status. In an attempt to improve this situation, the European Register of Cystic Echinococcosis (ERCE), was launched in October 2014 in the context of the HERACLES project. ERCE is a prospective, observational, multicentre register of patients with probable or confirmed CE. The first ERCE meeting was held in November 2015 at the Italian National Institute of Health (Istituto Superiore di Sanita, ISS) in Rome, to bring together CE experts currently involved in the Register activities, to share and discuss experiences, and future developments.Although the Register is still in its infancy, data collected at the time of writing this report, had outnumbered the total of national cases reported by the European endemic countries and published by the European Centre for Disease Prevention and Control in 2015. This confirms the need for an improved reporting system of CE at the European level. The collection of standardized clinical data and samples is expected to support a more rational, stage-specific approach to clinical management, and to help public authorities harmonize reporting of CE. A better understanding of CE burden in Europe will encourage the planning and implementation of public health policies toward its control.

This study is a retrospective inquiry among children operated for hydatid cyst which were diagnosed with at least one relapse episode. The study-group consisted of 160 children out of which 110 were submitted to at least one surgical procedure and 35 out of 110O presented hydatidosis relapses. The post-operative monitorization of children with hydatidosis must be extended over a 2-year-period (69.29%) time during which most of the relapses occur. The organs being most frequently affected are primary the liver and secondary the lung. The secondary hydatidosis is more frequent "at distance" from the residual cavity than "in situ". The parasitic control is centered on the imagistic test: abdominal ultrasound, lungradiography and the serological surveillance of specific antibodies of IgG class which can remain positive during the whole life with decreasing titers in time. The antiparasitic treatment pre- and post- operative can complete the therapeutic schedule in the case of hydatidosis in order to assure the recovery.

Fever occurring during or after a period of time spent in a tropical area is an important element for both patient and the doctor attending him and having to cope with a varied differential diagnosis. First of all, it should be appreciated whether or not the case is an emergency, the admittance in the hospital being compulsory, or the case can be investigated in ambulatory. The differentiation between a "tropical fever" and a common one should be rapidly done, as certain tropical diseases have to be notified and isolation of the patient, identification of the new cases and contacts are recommended. A very carefully anamnesis, in order to define the place, period of time, the purpose of the travel, the specific chemoprophylactic measures, if other travellers have the same complaints should be done and a very good knowledge on the geography of parasitic and infectious diseases is required. Fever can be either acute or chronic. The clinical signs and symptoms accompanying the fever (rash, conjunctival chemosis, haemorrhages, flu like syndrome, jaundice, pulmonary signs, diarrhoea, hepatosplenomegaly, lymphadenopathy), will be considered in a context of a thorough differential diagnosis. The first choice laboratory investigations have to be completed with the specific ones and the quality of the laboratory, mainly in parasitology is essential. The first attitude, when the suspicion of tropical fever occurs, is to perform a systematic evaluation for malaria diagnosis. Travel medicine advice becomes indispensable and, if it is performed by a qualified person, it is very efficient. The recommendations have to take into account the purpose of the travel, the age, immune status and associated pathology of the subject, being adapted and personalized.
