Bovine mastitis has been assessed through somatic cells or clinical cases by farmers and vets but most of the time the perfect combination of both data remains unavailable. We tried to implement a new strategy of identification of mastitis-related costs, epidemiological impact and key periods of management. We built an online system for clinical data capture, including facilities for administrative management of veterinary drugs. Herd prevalence rate (HPR) is assessed through clinical and subclinical data. Lactation incidence rate (NIR) and cure rate (CR) were calculated for the period (depending on type of DHI control) using subclinical thresholds (primiparous > 150.000 cells/ml and multiparous >250.000 cells/ml) and clinical cases in susceptible animals (healthy or diseased). Dry-off period is studied through the Dry-off cure rate (DOCR) and new infection rate at first control (NIFC). The average number of cow-day-at-risk was 73.6 (StD=34.80). Mean HPR was 33 % (StD =11%); the average NIR was 16% and CR 35%. Mean DOCR was 62% with an NIFC of 23%. Regarding a mean loss for mastitis of 71€ per cow-year, the average difference was +40.7€ (StD=66.7€). It is explained partly by DOCR (R²=0.20; β=-131; p<0.0001). NIR is mainly influenced by HPR, but mainly by primiparous infection rate (R²=0.36; β= 0.33; p<0.0001). Those figures are coherent with subclinical data indicating that multiparous cows are becoming more and more infected, limiting efficacy of dry-off therapy. Communication has to be done around dry-off and preventive measures in primiparous cows. As CR had few significant impact on global udder health, cure at the herd level should more be regarded as cow ability to cure in its environment than by considerations on medication once infected.

Onychomycosis is a common condition in the adult population. It has been reported to be more prevalent in association with some specific diseases including psoriasis. This study using combined histomycology and cultures was performed on nail clippings collected from thickened dystrophic toenails in 233 eligible psoriatic patients. Onychopathies associated with psoriasis were more numerous in men. Their prevalence increased up to the age of 40 and remained stable thereafter. A total of 42/233 cases were diagnosed as onychomycoses. These infections were more prevalent in middle-aged men. The identified infectious agents (35/42 cases) frequently corresponded to dermatophytes, but Candida albicans was also implicated, particularly in women. (c) 2006 Elsevier Masson SAS.

Prolactin-secreting tumors (prolactinomas), the most frequently occurring pituitary tumor, have a frequency that varies with age and sex. They occur most frequently in females aged 20 to 50 years old, at which time the female-to-male ratio is approximately 10:1. In the pediatric-adolescent age group, prolactinomas have a prevalence of 100/million population, and account for less than 2% of all intracranial tumors. Prolactinomas occur in approximately 30% of patients with multiple endocrine neoplasia type 1 and in this setting, they may be more aggressive than their sporadic counterparts. Patients with Carney complex or McCune-Albright syndrome may exhibit hyperprolactinemia due to a pituitary tumor derived from somatomammotropic cells that secrete both growth hormone and prolactin. Few familial cases of prolactinoma unrelated to MEN-1 are reported in literature. [less ▲]

Phenotypically, the transition from early to late Crohn's disease is characterized by the occurrence of complications including strictures, intra-abdominal fistulas and perianal fistulas, all of them leading to various types of surgeries and currently non-reversible tissue damage. It must, however, be kept in mind that this transition is not at all a uniform and linear process. According to these simple phenotypic criteria, Crohn's disease can already be a late disease at diagnosis while in other patients, it can still be an early disease after 20 years of evolution. This simply highlights the relativity of time in this field, actually reflecting the nature, location and severity of the inflammatory process. The risk over time of the development of these complications has been described, first in cohort studies and then in population-based studies. Globally, at diagnosis, between 19 and 38% only of Crohn's disease patients have complicated Crohn's disease. After 10 years, between 56 and 65% of patients have developed either stricturing or penetrating complications. After 20 years, these numbers are between 61 and 88%. In parallel to these structural changes, changes in the immunobiology of the disease also seem to occur; the latter seem to happen quicker with major modification already within 2 years of the diagnosis. Beside these general figures, important questions remain pending. First, the real timing of these changes is still unclear. Second, the precise role of genetics and environment in the development of these changes remains to be clarified. Third, the correlation between changes in immunobiology and intestinal structural damages has not been specifically studied. [less ▲]

Selenium (Se), iodine (I), zinc (Zn) and copper (Cu) deficiencies in cattle have been reported in Europe. These deficiencies are often associated with diseases. The aim of the study was to assess trace element status in Belgian cattle herds showing pathologies and to compare them to healthy cattle herds. Eighty-two beef herds with pathologies, 11 healthy beef herds, 65 dairy herds with pathologies and 20 healthy dairy herds were studied during barn period. Blood and/or milk samples were taken in healthy animals. Plasma Zn, Cu, inorganic I (PII) and activity of glutathione peroxidase in erythrocytes (GPX) were assayed. In milk, I concentration was measured. Data about pathologies and nutrition in the herds were collected. According to defined thresholds, it appeared that a large proportion of deficient herds belonged to "sick" group of herds. This conclusion was supported by the mean value of trace elements and by the fact that a majority of individual values of trace elements was below the threshold. Dairy herds had mean values of trace elements higher than beef herds. More concentrates and minerals were used in healthy herds versus "sick" herds. These feed supplements were also used more often in dairy herds, compared to beef herds. Trace elements deficiencies are present in cattle herds in Belgium and are linked to diseases. Nutrition plays a major role in the trace elements status. [less ▲]

Metabolic and morphologic abnormalities in persons with HIV remain common contributors to stigma and morbidity. Increased abdominal circumference and visceral adiposity were first recognized in the late 1990s, soon after the advent of effective combination antiretroviral therapy. Visceral adiposity is commonly associated with metabolic abnormalities including low HDL-cholesterol, raised triglycerides, insulin resistance, and hypertension, a constellation of risk factors for cardiovascular disease and diabetes mellitus known as "the metabolic syndrome". Medline and conference abstracts were searched to identify clinical research on factors associated with visceral adiposity and randomized studies of management approaches. Data were critically reviewed by physicians familiar with the field. A range of host and lifestyle factors as well as antiretroviral drug choice were associated with increased visceral adiposity. Management approaches included treatment switching and metformin, both of which have shown benefit for insulin-resistant individuals with isolated fat accumulation. Testosterone supplements may also have benefits in a subset of individuals. Supra-physiological doses of recombinant human growth hormone and the growth hormone releasing hormone analog tesamorelin both significantly and selectively reduce visceral fat over 12-24 weeks; however, the benefits are only maintained if doping is continued. In summary, the prevention and management of visceral adiposity remains a substantial challenge in clinical practice. [less ▲]
