Working memory problems have been identified as a core cognitive deficit in schizophrenia. In this paper, we present the results of a cognitive rehabilitation programme (Duval & Coyette, 2005) administered to a schizophrenia patient, and specifically designed to improve the updating sub-component of working memory. The original feature of this programme was that it involved two types of updating exercises: cognitive and ecological. The purpose was to enable the patient to acquire cognitive strategies that alleviate the mental load of the central executive and to transfer them to daily life. The specificity and efficacy of the programme were assessed with multiple (cognitive, ecological and non-target) baseline measurements. In addition, several questionnaires were administered to assess the effect of the programme on subjective cognitive complaints affecting daily life, psychiatric symptoms and self-esteem. The results demonstrated the efficacy of the rehabilitation programme on the updating function and the generalisation of these beneficial effects to daily life. A significant decrease in both subjective cognitive complaints and psychiatric symptoms was also observed. However, the patient's self-esteem did not improve. [less ▲]

The vegetative state (VS) is defined as a condition of wakefulness without awareness. Being awake and being asleep are two behavioral and physiological manifestations of the daily cycles of vigilance and metabolism. International guidelines for the diagnosis of VS propose that a patient fulfills criteria for wakefulness if he/she exhibits cycles of eye closure and eye opening giving the impression of a preserved sleep–wake cycle. We argue that these criteria are insufficient and we suggest guidelines to address wakefulness in a more comprehensive manner in this complex and heterogeneous group of patients. Four factors underlying wakefulness, as well as their interactions, are considered: arousal/ responsiveness, circadian rhythms, sleep cycle, and homeostasis. The first refers to the arousability and capacity to, consciously or not, respond to external stimuli. The second deals with the circadian clock as a synchronizer of physiological functions to environmental cyclic changes. The third evaluates general sleep patterns, while homeostasis refers to the capacity of the body to regulate its internal state and maintain a stable condition. We present examples of reflex responses, activity rhythms, and electroencephalographic (EEG) measurements from patients with disorders of consciousness (DOC) to illustrate these factors of wakefulness. If properly assessed, they would help in the evaluation of consciousness by informing when and in which context the patient is likely to exhibit maximal responsiveness. This evaluation has the potential to improve diagnosis and treatment and may also add prognostic value to the multimodal assessment in DOC. [less ▲]

BACKGROUND/OBJECTIVE: Sensitive/reactive skin is regarded as a manifestation of sensory irritation. This susceptibility condition to various exogenous factors suggests the intervention of some neuropeptides and other neurobiological mediators. Mast cells are among the putative implicated cells. METHOD: The present immunohistochemical and morphometric study was performed on two groups of 36 gender- and age-matched subjects complaining or not from reactive skin as determined by electric current perception. In the mid upper part of the dermis, the numerical density in mast cells and the size of the microvasculature were assessed distinguishing the blood and lymphatic vessels. RESULTS: Globally, the distributions of data were large in reactive skin. This condition was characterized by a prominent increase in both the numerical density in mast cells and the overall size of the lymphatics. By contrast, no difference was found in the size of cutaneous blood vessels. More precisely, it appeared that a subgroup of people with reactive skin exhibited these changes contrasting with some other individuals whose data remained close to the normal range. CONCLUSION: Mast cells and lymphatics are probably involved in the process of sensory irritation affecting a subgroup of the population. [less ▲]

Skin weathering and photoaging of the balding scalp have not attracted much investigative attention so far. However, the concept of field cancerization, in particular actinic field carcinogenesis, is likely applicable to this body region. The aim of the study was to finetune the epidermal actinic changes present on hairlessness scalp. The ultraviolet light-enhanced visualization (ULEV) method was used to assess a series of 50 healthy men older than 50 years with documented baldness for over 15 years. They were scrutenized looking for altered epidermal structures corresponding to photoaging-associated changes. Attention was focused on the faint mosaic melanoderma (FMM) and atypical scaliness. Observations were made on the scalp and forehead. FMM was recognized in each case. It presented either as a single manifestation of photoaging or it was associated with an unusual pattern of discrete rimmed scaliness. In this latter case histology and morphometry disclosed keratinocyte dysplasia. A similar scaly pattern was not seen on the forehead. Subtle skin surface changes were disclosed on long-standing sun-exposed balding scalps. The scaly aspect was distinct from dandruff, seborrheic dermatitis or any other common inflammatory scalp dermatosis. The presently described changes had not previously been described during early balding. It is suggested that the presently described condition may be associated with or indicative for actinic field carcinogenesis and incipient keratinocyte dysplasia. [less ▲]

The damselfishes, with more than 340 species, constitute one of the most important families that live in the coral reef environment. Most of our knowledge of reef-fish ecology is based on this family, but their trophic ecology is poorly understood. The aim of the present study was to determine the trophic niches of 13 sympatric species of damselfishes by combining stable isotope (d15N and d13C) and stomach content analyses. Isotopic signatures reveal three main groups according to their foraging strategies: pelagic feeders (Abudefduf sexfasciatus, A. sparoides, A. vaigiensis, Chromis ternatensis, C. dimidiata, Dascyllus trimaculatus and Pomacentrus caeruleus), benthic feeders (Chrysiptera unimaculata, Plectroglyphidodon lacrymatus and Amphiprion akallopisos) and an intermediate group (D. aruanus, P. baenschi and P. trilineatus). Stomach contents reveal that planktonic copepods and filamentous algae mainly represent the diets of pelagic feeders and benthic feeders, respectively. The intermediate position of the third group resulted from a partitioning of small planktonic prey, small vagile invertebrates and filamentous algae. In this last feeding group, the presence of a wide range of d13C values in P. trilineatus suggests a larger trophic niche width, related to diet-switching over time. Some general considerations about the feeding habits of damselfishes reveal that their choice of habitat on the reef and their behavior appear to be good predictors of diet in this group. Benthic (algae and/or small invertebrates) feeders appear to be solitary and defend a small territory on the bottom; zooplankton feeders remain in groups just above the reef, in the water column.

A series of skin cancers are more frequent or show a worsened course and outcome in HIV-treated patients. The leading neoplasms correspond to basal and squamous cell carcinomas, some primary cutaneous lymphomas and malignant melanomas. In theses patients, early diagnosis and radical treatment on sight should be considered. [less ▲]

Most studies of fish sounds show that the sounds are species-specific, with unique spectral and timing characteristics. This raises the question as to whether these sounds can be used to understand phyletic relationships between species and which acoustic parameters are subject to variation between species. In the present study, 597 sounds (and 2540 pulses) related to signal jumps of four Dascyllus species (Dascyllus aruanus, Dascyllus trimaculatus, Dascyllus albisella, and Dascyllus flavicaudus) from different geographic regions (Madagascar, Moorea, Rangiroa, and Hawaii) were analysed. It was possible to discern species-specific sounds, but also variation in sounds between populations. Large variations in sound length were found between Dascyllus species, whereas differences in interpulse duration were found to be variable between populations. In the regions where species live in sympatry, it appears that they restrict the variability in their sounds. This could comprise evidence of adaptation with character displacement of sonic characteristics where different species co-occur. However, sonic characteristics still overlapped substantially between species, suggesting that females would need to sample more than one sound and potentially use other cues to discriminate between species.

Hypertensive disorders of pregnancy (HDP) represent globally 10% of human births and their major complication, preeclampsia, 3 to 5%. The etiology of these HDP remains still uncertain, however major advances have been made these last 25 years. The Sixth International Workshop on Reproductive Immunology, Immunological Tolerance and Immunology of Preeclampsia 2008 celebrated its 10th Anniversary in Reunion-island (French overseas Department in the Indian Ocean). Over this decade, these six workshops have contributed extensively to immunological, epidemiological, anthropological and even vascular debates. The defect of trophoblastic invasion encountered in preeclampsia, intra-uterine growth retardation and to some extend also preterm labour has been understood only at the end of the 1970's. On the other hand, clinical and epidemiological findings at the end of the 20th century permitted to apprehend that “preeclampsia disease of primiparae” may in fact well be the disease of first pregnancies at the level of human couples. Among the important advances, immunology of reproduction is certainly the topic where knowledge has literally exploded in the last decade. This paper relates some major steps in comprehension of this disease and focuses on the interest to follow these immunological works and their new concepts. It seems, at the beginning of the 21st century, that we are possibly closer than ever to understand the etiology of this obstetrical enigma. In this quest, the immunology of reproduction will certainly come out as one of the main players. [less ▲]

BACKGROUND: The incidence of syphilis is on the rise in many cities worldwide. Both the clinical and histopathological changes do not always fulfil the typical diagnostic criteria. Immunohistochemistry is available to identify and localize Treponema pallidum. Two main patterns of T. pallidum distribution were described in the skin, namely heavy intraepidermal infiltration and scattered pattern inside the lichenoid cell infiltrate. OBJECTIVE: To search for a third pattern consistent with dissemination of the disease. METHODS: Immunohistochemistry using an antispirochete (T. pallidum and Borrelia) antibody was used in all cases of syphilis submitted to our laboratory. In addition, deposits of immunoglobulins and complement indicative of immune complexes were searched for. RESULTS: According to the cases, T. pallidum was disclosed in a combination of three patterns. The previously described epidermal and lichenoid patterns were confirmed, and a third pattern predominating in a perivascular location throughout the dermis was clearly identified in primary syphilis. The microorganisms were abundant in extracellular and intracellular locations, particularly inside endothelial cells. No deposits of immunoglobulins and complement were disclosed. CONCLUSION: The perivascular cuff of T. pallidum throughout the dermis might be representative of the dissemination phase of T. pallidum. [less ▲]
