RESUMO
Image-guided percutaneous treatments for echinococcal cysts were introduced in the mid-eighties. Today they represent a third therapeutic option, after surgery and benzimidazole derivatives. Two types of percutaneous treatments are available, based on the destruction of the germinal layer or the evacuation of the endocyst. To assess the extent of their use and their safety, a Medline search of the literature on this subject was performed. The number of cysts treated, their anatomical sites, the complications and, length of follow-up (when available), were all examined. The results show that percutaneous treatments for cystic echinococcosis are safe and efficacious in selected anatomical sites, provided basic safety issues are correctly addressed. However, before drawing final conclusions, a more detailed analysis of the literature is needed. Percutaneous treatments could be simplified and made more effective if a scolecidal agent could be found that melts the entire endocyst without causing harm to the biliary epithelium.

Surgical excision of echinococcal cyst has long been considered the only effective treatment for echinococcosis. However, the remarkable advances in imaging techniques, particularly ultrasound, made during the past 25 years have greatly facilitated diagnosis, treatment and follow-up. Today, chemotherapy and percutaneous treatments have become widely available. A major step forward in management of the disease came in 2001, when the WHO International Working Group on Echinococcosis (WHO-IWGE) came to a consensus by developing a standardized classification of ultrasound images in cystic echinococcosis. Thus, the most appropriate treatment for patients affected by this serious and sometimes life-threatening disease may now be chosen. An overview of the three main therapeutic options for abdominal- and particularly hepatic-cystic echinococcosis is presented, with focus on the indications and contraindications of each one. Data from long-term follow-up studies are also discussed, with emphasis on the resulting stage-specific criteria for treatment.

The availability and the reduced costs of more sophisticated electronic devices makes possible to develop and use sophisticated systems also for domestic use. This opportunity beside new emerging market needs is bringing to new life the Home-Care scenario. This paper will present a Home Care system developed in the context of the FUTUREHOME IST project. Its key features are interacting with external health-care service providers, such as the Hospitals, Private Clinics or Emergency Departments, from our own houses by means of innovative solutions. It enables the telemonitoring of vital parameters of the home/family members. Using wireless connections, data collected from different devices (weight scale, ox-meter, glucose meter, etc...), are stored into the Home Network Service Point (HNSP), the FUTUREHOME network's core, from where they are used for further consultations (e.g. patients follow-up).

BACKGROUND: Percutaneous drainage of pyogenic liver abscess has become first-line treatment. In the past surgical drainage was preferred in some centres. AIM: The aim of this retrospective study was to assess the effectiveness of percutaneous treatments and surgical drainage, in terms of treatment success, hospital stay and costs. PATIENTS: Data of 148 patients (90 males; 58 females; mean age, 61 yrs; range, 30-86 yrs) were retrospectively analysed. METHODS: Patients' outcomes, including the length of hospital stay, procedure-related complications, treatment failure and death, were recorded. Multiple logistic regression model was used for statistical analysis. RESULTS: One hundred and four patients (83 with solitary and 21 with multiple abscesses) were treated percutaneously, either by needle aspiration (91 patients) or catheter drainage (13 patients) depending on the abscess's size, and 44 patients (30 with solitary and 14 with multiple abscesses) were treated surgically. There was no statistically significant difference in patients' demographics or abscess characteristics between groups. Hospital stay was longer, and costs were higher in patients treated surgically (p<0.001). There was statistically significant difference in morbidity rate between groups (p<0.001). No death occurred in both groups. CONCLUSIONS: Percutaneous and surgical treatment of pyogenic liver abscesses are both effective, nevertheless percutaneous drainage carries lower morbidity and is cheaper.

Patients with AIDS present a wide variety of clinical manifestations through involvement of various organs. Ultrasonography (US) is easy to perform, safe, inexpensive, not invasive and repeatable. Those features are crucial for AIDS patients, who in industrialised countries are now mostly seen on an outpatient basis thanks to the introduction of Highly Active Antiretroviral Therapy. US can investigate most of the organs affected in AIDS and can guide biopsies, allowing the cyto-histological and microbiological investigations needed for a definitive diagnosis. This paper reviews the wide variety of applications of abdominal US and stresses its importance in the management of a complex and changing condition, particularly in settings where other more expensive imaging techniques are not--and will not be for a long time--available. The increasing use of portable/hand-carried scanners further adds to the value of the technique in such settings. With new treatments, prevalence and morbidity/mortality rates change, but new conditions and new side effects appear. US applications to these new conditions are discussed as well.
