Unicentric or multicentric castleman disease? A case report of a pelvic intraperitoneal mass in a middle aged woman

Castleman Disease is a lymphoid disorder characterized by the presence of an enlarged or abnormal lymph node/lymphatic tissue. The disease is classified into unicentric or multicentric variants. The unicentric form is a benign disorder that is usually asymptomatic and consists of a single lymphoid mass that is predominantly located in the mediastinum, but can also rarely develop in the neck or abdomen. The multicentric type involves more than one lymphatic station and is related to the presence of type B symptoms (fevers, night sweats and weight loss), HIV/HHV8 infection and increased serum IL-6 levels. We present the case of an unusual pelvic intraperitoneal manifestation of Castleman Disease in a 52-year-old caucasian woman who showed clinical, radiological, histological and laboratory findings common to both Unicentric and Multicentric Castleman Disease

I costi dell’influenza in Italia

The influenza is an acute viral infection that strikes respiratory tract and its diffusion is characteristic of epidemic and pandemic reoccurence. Globally the influenza represents, for the entity of its social impact (measurable in terms of morbility, hospitalization and mortality), a heavy healt care problem. In Italy the estimated incidence is 10-15%: the influenza is the third death cause for infectiuos disease, after AIDS and tubercolosis. This study is based on the Studio 606, the first italian study that allow us to pass from the presumptive phase to the observational one. The Studio 606 has been projected and realized by the Società Italiana di Medicina Generale (SIMG), involving about 200 general practitioners (MMG) in two sample region, Lombardia and Puglia. The study has been developed between December the 15th, 1998 and March the 15th, 1999. The influenza causes especially indirect costs: most of people affected with influenza doesn’t go to work for about five days and these absences create an average cost per capita of £558.000. This indirect cost represents 87% of total average cost of one single influenza event

Il costo sociale del morbillo in età pediatrica. L’epidemia a Palermo nel 1996-97

Objective To determine the direct and indirect costs associated with a measles epidemic occurring between September 1996 and August 1997 in Palermo (Italy) in paediatric-aged patients. Design A total of 2,029 cases of measles in a paediatric patient population were identified from a total of 38 paediatricians databases (24% of total). An extrapolation to the general population was then performed to estimate a total of 9,059 cases. Patient information obtained from the database such as patient age, risk factors, complications, vaccination history, as well as caretaker’s profession were included in a questionnaire compiled for each patient. Setting Inpatient and outpatient clinics in Palermo, Italy. Patients and participants Participants were paediatric-aged patients who had been diagnosed with measles. Included in the study was a group of previously vaccinated patients (6%). Main outcome measures and results The average cost of care was 464.000 Italian lire (Lit.) per case with a total cost of Lit. 4,2 billion for the entire epidemic. The direct costs comprehended 46.6% (Lit. 217.000 per case) of the total costs related to the measles epidemic and were subdivided according to in-patient care (55.4%), paediatric outpatient visits (33.5%) and drugs (9.7%). The average health-care cost associated to previously vaccinated patients (6%) was lower than for non-vaccinated patients, Lit. 110.000 vs Lit. 223.000 per case, respectively. Conclusion The demographic and economic data obtained highlights not only the social and economic impact of the epidemic, but also provides relevant information useful for cost-effectiveness analysis

A practical algorithmic approach to mature aggressive B cell lymphoma diagnosis in the double/triple hit era. Selecting cases, matching clinical benefit. A position paper from the Italian Group of Haematopathology (G.I.E.)

An accurate diagnosis of clinically distinct subgroups of aggressive mature B cell lymphomas is crucial for the choice of proper treatment. Presently, precise recognition of these disorders relies on the combination of morphological, immunophenotypical, and cytogenetic/molecular features. The diagnostic workup in such situations implies the application of costly and time-consuming analyses, which are not always required, since an intensified treatment option is reasonably reserved to fit patients. The Italian Group of Haematopathology proposes herein a practical algorithm for the diagnosis of aggressive mature B cell lymphomas based on a stepwise approach, aimed to select cases deserving molecular analysis, in order to optimize time and resources still assuring the optimal management for any patient

Quantum diffusion with disorder, noise and interaction

Disorder, noise and interaction play a crucial role in the transport properties of real systems, but they are typically hard to control and study both theoretically and experimentally, especially in the quantum case. Here we explore a paradigmatic problem, the diffusion of a wavepacket, by employing ultra-cold atoms in a disordered lattice with controlled noise and tunable interaction. The presence of disorder leads to Anderson localization, while both interaction and noise tend to suppress localization and restore transport, although with completely different mechanisms. When only noise or interaction are present we observe a diffusion dynamics that can be explained by existing microscopic models. When noise and interaction are combined, we observe instead a complex anomalous diffusion. By combining experimental measurements with numerical simulations, we show that such anomalous behavior can be modeled with a generalized diffusion equation, in which the noise- and interaction-induced diffusions enter in an additive manner. Our study reveals also a more complex interplay between the two diffusion mechanisms in regimes of strong interaction or narrowband noise.Comment: 11 pages, 10 figure
