How long does the volumizing effect of a Zingiber officinale-based lip plumper last?

OBJECTIVE: Lip plumpers should enhance lip volume. It has been shown that no noticeable result was obtained after long term use of these products. The present study has been carried out to assess lip plumpers' short term effectiveness within 2 h from application. METHODS: Effectiveness was assessed using non-invasive techniques. The effect on vascularisation was analyzed with the Mexameter MX 16® , and the volume enhancing effect was assessed by anthropometric measures and profilometry analysis from 3D scanning electron microscope (SEM) images using Alicona's MEX software. Sixty female volunteers were recruited for the study and the measurements were taken 15, 30, 60, 90 and 120 min after product application. RESULTS: Product application produced a statistically significant increase of lip vascularisation during the first 15 min, which stayed unchanged until the 30th min, then decreased in intensity. The volumizing effect was revealed by 3D profilometry analysis only, not by anthropological measurements. The use of 3D SEM images showed an increase of 0.50 mm in the protrusion of the lip vermilion (MHP parameter) during the first 15 min from product application. CONCLUSION: Results suggest that the lip plumper temporarily enhances vasodilation and increases lip volume.

An epidemiological survey on the allergological importance of some emerging pollens in Italy.

Epidemiological studies on the pollens responsible for allergic diseases throughout Italy are lacking. Routine diagnostic panels consist prevalently of grass, Parietaria, weeds, birch, olive and mugwort. Considering the great variety of Italian geographical areas and the observation of the growing allergological importance of new botanical species (e.g., ambrosia), a survey on pollen species considered "minor" was necessary. A panel of "emerging" pollens (birch, hazelnut, alder, hornbeam, cypress, ragweed) and a routine panel were used to skin prick test 2,934 consecutive outpatients with respiratory pathology of suspected allergic origin, in 21 centers across Italy. A specific questionnaire was compiled. It was found that 20.1% of patients did not react to allergens tested, 28.2% were positive for at least one emerging pollen and 51.7% did not react to emerging pollens but tested positive for at least one allergen from the routine panel. The prevalence of single pollen species was related to geographical areas. Ragweed pollen was shown to provoke asthma much more frequently than other pollens. Hitherto scarcely considered pollens play a considerable role in causing allergic diseases in Italy. In the great majority of patients, positivity for these pollens was associated with positivity to the better recognized group of pollen allergens, although in some cases they were the primary pathogenic agent. We suggest that these more recently considered allergens be included in routine diagnostic panels.

Clinical study on Alternaria spores sensitization.

BACKGROUND: sensitization to fungi spores is often associated with sensitization to other allergens and so it is difficult to estabilish the exact cause of illness. OBJECTIVE: the aim of the study was to evaluate a group of patients monosensitized to Alternaria and to establish the prevalence, periodicity and clinical profile of this kind of sensitization. METHODS: 37 subjects who were monosensitized to Alternaria (prick-test positive), according to a previous epidemiological study were evaluated. Clinical symptoms and the period of their occurrence were taken into consideration as well as immunological parameters (RAST). RESULTS: 20 patients (over 50%) included in the study proved to be affected by asthma associated with other allergic symptoms and 22 patients (60%) presented perennial symptoms. The RAST carried out on 34 monosensitized subjects proved positive in 11 and negative in 23. CONCLUSIONS: Alternaria sensitization is characterized by a perennial periodicity with severe respiratory symptoms (asthma) which occur primarily in children. Prick test is preferable to and more reliable than RAST as a diagnostic test.

Introducción: la sensibilización a esporas de hongos se asocia frecuentemente con la sensibilización a otros alergenos, con lo que es difícil establecer la causa exacta de la enfermedad. Objetivo: la finalidad del estudio fue evaluar a grupos de pacientes monosensibilizados a Alternaria y establecer la prevalencia, periodicidad y perfil clínico de esta clase de sensibilización. Métodos: se estudiaron 37 pacientes monosensibilizados a Alternaria (prick test positivo) seleccionados en un estudio epidemiológico previo. También se consideraron los síntomas clínicos y su frecuencia, así como algunos parámetros inmunológicos (RAST). Resultado: 20 pacientes (por encima del 50 por ciento) padecían asma asociada con otros síntomas alérgicos y 22 pacientes (60 por ciento) presentaban síntomas perennes. El RAST llevado a cabo en 34 pacientes monosensibilizados, fue positivo en 11 y negativo en 23. Conclusiones: la sensibilización a Alternaria se caracterizó por ser perenne, cursar con síntomas respiratorios graves (asma) y tener lugar principalmente en niños. Es preferible y más fiable como test diagnóstico el test cutáneo que el RAST. (AU)

Prevalence of sensitization to Alternaria in allergic patients in Italy.

BACKGROUND: The actual prevalence of sensitization to Alternaria is not known, partly due to the unreliability of diagnostic extracts. OBJECTIVE: To assess skin positivity to extracts of Alternaria in a wide population of Italian patients suffering from respiratory symptoms using a biologically standardized extract. METHODS: A total of 2942 patients were skin prick tested with Alternaria, and a panel of common inhalant allergens. Blood samples for specific IgE quantitation were taken both from patients positive and from patients negative (control group) to Alternaria extract. RESULTS: Three hundred six patients (10.4%, ranging from 1.8% in Turin to 29.3% in Cagliari) were positive to Alternaria; 37 were sensitized to only this mold, while the remaining 269 were sensitized to at least one other allergen. Of the Alternaria-positive patients, 79.7% suffered from rhinitis and 53.3% from asthma, either alone or associated with other symptoms. CONCLUSIONS: We suggest that, at least in Italy and in countries with similar climatic and environmental situations, standardized Alternaria extract should be included in the panel commonly used in investigating the allergen responsible in patients suffering from respiratory allergy.

Mab labelled liposomes as selective vehicles for drugs in H.I.V. infected cells.

CONCLUSION: Being able to carry zidovudine (AZT) at known concentrations into CD4+/CD38+ and CD14+ cells permits: - to reduce the drug dosage and to increase the interval for administration (until 1 dose I.V. every week); - to modulate the drug concentration into the CD4+/CD38 an CD14+ cells in relation to the "in vitro" determined HIV sensitiveness; - to eliminate haematological, medullary and general toxicity; - to be able to treat severely hill patients. Further studies are necessary in order to: - To find out the better phase to start the therapy; - To use several drugs with different mechanisms of action in order to slow down as much as possible the presence of resistant viral strains. - As for other drugs which are beginning to be used with artificial vehicles, futher studies are required to improve the selectivity and safety of LIPOAZT for the target cells including macrophages.

Efficacy of teicoplanin and imipenem on respiratory infections in high risk patients.

The efficacy of teicoplanin and imipenem was assayed on microorganisms, mainly hospital opportunistic organisms, resistant to common therapy, isolated from bronchoaspirates of high risk hospitalized patients. Imipenem has shown remarkable activity against all isolated microorganisms with sensitivities ranging from 91.93% against Acinetobacter calcoaceticus to 75.86% against Pseudomonas sp. Teicoplanin has shown excellent activity against Staphylococcus aureus (sensitivity 83.66%).

[Pathology caused by acari]. / La patologia da Acari.

This report concerns the observations the Authors have been carrying out for over twelve years in Sardinia; they regard the sensitization to house dust mites (Dermatophagoides pteronyssinus, Dermatophagoides farinae) and to storage mites (Acarus siro, Glycyphagus domesticus, Lepidoglyphus destructor, Tyrophagus putrescentiae) and are been obtained with: 1) skin tests with mite extracts; 2) RadioAllergoSorbentTest (RAST) for specific IgE and IgG; 3) mite exposure in homes and mite analysis; 4) hyposensitisation with personal time-lag vaccines holding one or more "storage" or "house dust" mites. They are been prepared on the ground of RAST, skin tests, clinical symptomatology and environmental exposure to mites; 5) clinical control after therapy with vaccines for a period of five till to ten years. The Authors obtained unusual results.

[Pneumocystis carinii in male drug addicts: morphologic study of the parasite]. / Pneumocystis carinii in paziente tossicodipendente maschio: studio morfologico del parassita.

This work describes the first case of Acquired Immuno-Deficiency Syndrome (AIDS) to be found in Sardinia. The patient was an adult male drug-addict who died following a respiratory inadequacy due to bronchial pneumonia resulting from Pneumocystis carinii (PCP). For diagnostic purposes the emphasis is laid on the importance of morphological research into the parasite, considering the lack of specific evidence regarding serological investigation. Therefore, the various techniques of coloration are examined here. That which stands out for its simplicity of performance and its thoroughness of investigation is the May-Grünwald-Giemsa coloration which also points out other micro-organisms frequently associated with this type of pathology. In conclusion, then, this work indicates the advisability, on behalf of the Services of Anatomy and Pathological Histology to adopt, as routine practice the specific colorations for Pneumocystis carinii (PC), taking into account the considerable diffusion of this parasite in patients with immuno-deficiency.

[Domestic Acari in Sardinia]. / Gli acari domestici in Sardegna.

In Sardinia, a great Mediterranean island, house dust mites allergy is very spread. This investigation was carried out to determine the species, occurrence and abundance of mites in the house dust of sensitized subjects. 55 samples of house dust were examined and the mites fauna identified. Dermatophagoides pteronyssinus was the most abundant (54% of the found mites), and the most frequent mite (94.5%). Two others pyroglyphid species were recovered: Dermatophagoides farinae and Euroglyphus maynei that were common in Sardinian house dusts. The frequency with which E. maynei was found in this region (50%) suggests that he may well be an important cause of allergy in this region underestimated. Several species of storage mites were common in house dust, chiefly Glycyphagid and Acarid species, that have been shown to provoke strong reactions in sensitized subjects. The Mediterranean climate, and its effect on the physical conditions within the house, and the personal life style of the inhabitants are the most important factors associated with high mite numbers in Sardinian house dust.

Recurrence of Pelecypod-associated cholera in Sardinia.

From Oct. 30 to Nov. 7, 1979, 10 people in the Sardinian province of Cagliari had onset of bacteriologically confirmed cholera. Two symptom-free excretors of Vibrio cholerae O:1 were detected in household contacts of the patients. There were no deaths. All but 1 of the 12 people with V. cholerae O:1 infection gave a history of recent consumption of marine bivalves known locally as arselle (pelecypods). Triplicate matched neighbourhood controls for each of the first 7 cases identified were also interviewed; none had recently eaten arselle. V. cholerae O:1 was also recovered from samples of water and bivalves obtained from a lagoon on the outskirts of the city of Cagliari. Arselle had also been implicated as the vehicle of transmission in 1973 in the last outbreak of cholera in Sardinia. It seems unlikely that cholera transmission had persisted locally in the interim.
