Medical significance of peroxisome proliferator-activated receptors.

1999

Peroxisome proliferator-activated receptors (PPAR) were discovered in 1990, ending 25 years of uncertainty about the molecular mechanisms of peroxisome proliferation. Subsequently, PPARs have improved our understanding of adipocyte differentiation. But there is more to PPARs than solving a puzzle about an organelle (the peroxisome) long considered an oddity, and their medical significance goes beyond obesity too. Enhanced PPAR type alpha expression protects against cardiovascular disorders though the role of enhanced PPARgamma expression seems less favourable. PPAR mechanisms, mainly via induction of more differentiated cell phenotypes, protect against some cancers. The differentiation of m…

Multiple pulmonary and multivesicular interatrial septum hydatid cysts in a native italian patient

2008

Multivesicular, pulmonary and cardiac hydatidosis are rarely observed and can give rise to serious complications. Cysts can remain asymptomatic for a long time, until they reveal themselves perforating into cardiac chambers and/or pulmonary arteries or the systemic circulation. A rare case of multivesicular interatrial septum hydatid cyst with multiple pulmonary involvement in a native Italian farm labourer is reported. Clinical, radiological, serological and histological findings are described. MR imaging showed the exact anatomic location and the multivesicular nature of the cardiac cyst and was useful in planning surgical treatment. A successful outcome was achieved with a combination of…

Lipoma of the fossa femoralis mimicking a femoral hernia. Report of 2 cases

2018

Highlights • Femoral lipoma can be mistaken with femoral hernia. • Differential diagnosis between femoral lipoma and femoral hernia can result challenging. • The occurrence of femoral pain can lead to misinterpretation of the symptoms.

Role of fungus in eosinophilic sinusitis.

2005

Chronic rhinosinusitis is characterized by a broad diagnostic and etiologic spectrum. It has been postulated that fungal organisms might represent the immunologic target initiating and maintaining the disease process in patients with chronic rhinosinusitis as a common denominator. This review analyzes the available data to describe the current understanding of the role of fungus in the pathophysiology of chronic rhinosinusitis.Recent findings have demonstrated that using highly sensitive methods, the detection rate of fungi in nasal mucin can be increased to approximately 100% in patients and in healthy controls. If this ubiquitous fungal contamination were to be related to a causative mech…

Creating clear data about complications that can affect the quality of life is an important tool for patient…

Seducin, male sex pheromone of the cockroachNauphoeta cinerea: Isolation, identification, and bioassay.

1990

The male sex pheromone of the cockroachNauphoeta cinerea was isolated from adult sternal glands and identified by gas chromatography-mass spectrometry. This pheromone, which attracts females from a distance, is a multicomponent blend. It is composed principally of three compounds: 3-hydroxy-2-butanone (acetoin), 2-methylthiazolidine, and 4-ethyl-2-meth-oxyphenol. A mixture of synthetic compounds in a ratio of 4∶4∶1 (2700 ng) elicits maximal response and short latency of response by receptive females, similar to that induced by male sternal gland extracts. Tested separately, each compound induces a positive response, but the moving times spent by females are generally longer than with the mi…

Cost-effectiveness of screening for colorectal cancer in France using a guaiac test versus an immunochemical test

2010

Objectives: The aim of this study was to compare the cost and the effectiveness of two biennial fecal occult blood screening tests for colorectal cancer: a guaiac nonrehydrated test (G-FOBT) and an immunochemical test (I-FOBT) with the absence of screening.Methods: A Markov model was developed to compare these strategies in a general population of subjects aged 50 to 74 over a 20-year period.Results: Compared with the absence of screening, G-FOBT and I-FOBT were associated with a decrease in colorectal cancer mortality of 17.4 percent and 25.2 percent, respectively. With regard to cost-effectiveness, expressed as cost per life-year gained, I-FOBT was the most effective and most costly alter…

The Valencia consensus-based adaptation of the IASP complex regional pain syndrome diagnostic criteria

2021

Refereed/Peer-reviewed The new IASP diagnostic criteria for complex regional pain syndrome (CRPS) (aka “the Budapest Criteria”3; Table 1) have improved the diagnostic specificity for CRPS while maintaining good sensitivity. Internationally, these criteria are now in common use. The IASP CRPS Special Interest Group convened a workshop of CRPS experts in Valencia/Spain in September 2019 to review perceived ambiguities in the diagnostic text and issues identified in applying these criteria in both the research and clinical contexts. After this review, workshop attendees discussed and reached a consensus regarding adaptations to the diagnostic taxonomy text. This process resulted in pragmatic u…
