[Changes in the vaginal mucosal bacterial flora ecosystem during the menstrual cycle in women].

It was shown that bacteria of mucosae of higher organisms, mostly have specific receptors for chemical complementary structures of cell surface. On the other hand it is known already that vaginal flora changes during ovulation and afterwards, some infections begin and reveal during some periods of the ovulatory cycle. Therefore, it was studied the adherence of saprophytic and pathogenic bacteria to vaginal cell in different phases of the ovulatory cycle. It was shown that, during the cycle, the bacterial adherence changes because of environment modifications, caused by secretion under hormonal control.

Neodymium: yttrium-aluminum-garnet long impulse laser for the elimination of superfluous hair: experiences and considerations from 3 years of activity.

This study examined the results obtained with a modern apparatus for laser hair removal (neodymium: yttrium-aluminum-garnet [Nd:YAG] laser at long impulses with a wave-length of 1,064 nm; Q-switched laser) over a follow-up period of 3 years. A large heterogeneous group of 480 patients was taken into consideration. These patients were treated according to a standard protocol with monthly checkups and a personalized protocol at deferred appointments. The results, discovered by means of the most objective procedure possible, were retrieved and put into a graph showing two different curves for the repopulation of hair. In their clinical travels, the authors observed an average variable regrowth of 40% to 65%, allowing them to affirm that laser hair removal using Nd:YAG at long impulses is decisively efficient in obtaining long-term results. The use of a protocol (denominated "prolonged monthly checkup") with laser sessions at ever-decreasing periods permits, among other things, more outstanding and advantageous results for the patient. Thanks to more efficiently synchronized phases of the biologic hair cycle, this shortens and moves the telegenic phases closer and also renders the anagenic phases (those in which the selective photoermolysis on the pilipheric follicle proves to be efficient) more efficient. Personalization of the treatment relative to the monthly health checkup sessions is of fundamental importance to the scope of obtaining the best results in terms of cost-benefit rate, provided submassimal fluxes are (i.e., those well-tolerated by the patient) used. All this allows hair removal that is not definitive, but which becomes progressively permanent (i.e., characterized by ever-growing periods of lack of hair sustained by sporadic maintenance laser sessions based on the individual's necessity).

Blepharoplasty and otoplasty: comparative sedation with remifentanil,propofol, and midazolam.

Three different methods of sedation or sedoanalgesia using remifentanil, Propofol, or midazolam to increase intra- and postoperative comfort and to reduce neuroendocrine stress in patients who had undergone typical ambulatory cosmetic surgery under local anesthesia were studied. A sample of 90 patients who underwent upper and lower eyelid blepharoplasty to correct baggy eyelids or otoplasty to correct protruding ears was selected according to standard criteria for the study. Remifentanil provided the best tolerability profile and the most effective perioperative pain control among the substances studied, demonstrating it to be a valid drug for modern sedoanalgesia aimed at increasing the well-being of patients undergoing ambulatory cosmetic surgery.

Self-perception and self-esteem of patients seeking cosmetic surgery.

Cosmetic surgery represents a particular application of plastic surgery, in which the operative competence of the discipline is focused not on the correction of pathological disorders, but on the correction of some morphologic traits not accepted by the patients, or not adherent with the aesthetic canons of the time, although they are absolutely compatible with the norm. As a consequence, cosmetic surgery recognizes subjective indications. According to a particular literature on the subject, patients seeking these interventions would live a dualism between (their own) body image and inner self-image. Very psychotic case histories would come out of this. A base psychological approach adopted by the surgeon, competent both in the surgical and the psychological level, is absolutely needed. In this study, the psychological features of patients seeking cosmetic surgery were explored in an attempt to define common profiles or prevalent characteristics, and to isolate major psychiatric disorders. Patient self-esteem and physical self-perception also were investigated.

Stahl syndrome in clinical practice.

Stahl syndrome, known also as "Satiro's ear", is a deformation of the auricle described in the nineteeth century by Stahl who included it in a classification of various deformities of ear:-Helix transversus spleniformis-Crus anthelicis trifurcata-Crus superior turgidumAt present Stahl's ear is included in the second group for the abnonnal cartilaginous pleat which extends from the Crus anthelix to the edge of elix deforming in this way the regular curvature of ear and amplifying the triangular hole. It's frequently associated to other aesthetic deformities of the auricle itself and above all among oriental peoples; the pathogenetic origin of this deformation has to be connected with an hereditary, familial character confirmed by the diffusion of this deformation among the members of the same family, reaching its highest expression in identical twins where its manifestation is about at seventy-five percent. Besides the hereditary-familial hypothesis, we find a second hypothesis according to which the cartilaginous deformity is connected with an altered growth of an instrinsic muscle of ear, the transverse muscle [1,4]. The solution of the problem is surgical, through the Chongcet technique [9], modified and applied in the post-operating using particular remedies.

Secondary metabolites of Aspergillus exert immunobiological effects on human monocytes.

This project focused on the effects of aflatoxin B1 (AFB1), a food-contaminating mycotoxin produced by fungi, genus Aspergillus, on the release and genetic expression of some important cytokines, i.e., (interleukin-1 alpha (IL-1 alpha), IL-6, tumor necrosis factor-alpha (TNF alpha)) by human monocytes. Monocytes, preincubated for different time periods with concentrations of AFB1 ranging from 0.01 to 1.0 pg/mL, were then activated with bacterial lipopolysaccharide. Cytokine levels were measured by immunoassay and mRNA by cDNA amplification. Pretreatment of monocytes with AFB1 resulted in a decrease in IL-1, IL-6 and TNF alpha release already at a concentration of 0.05 pg/mL. The gene expression of the cytokines considered was drastically affected by treatment with AFB1. In fact, AFB1 completely blocked the transcription of IL-1 alpha, IL-6 and TNF alpha mRNAs, while it did not affect beta-actin mRNA at the concentrations used. It therefore appears that AFB1 exerts its effect on cytokine release through selective inhibition of specific mRNA, without affecting general protein synthesis.

Effects of Cetyltrimethylammonium naproxenate on the adherence of Gardnerella vaginalis, Mobiluncus curtisii, and Lactobacillus acidophilus to vaginal epithelial cells.

BACKGROUND AND OBJECTIVES: A decreased concentration or total disappearance of Lactobacillus acidophilus in the vagina constitutes a frequent observation in bacterial vaginosis. GOAL OF THE STUDY: Cetyltrimethylammonium naproxenate has been evaluated in vitro to detect antiadhesive properties at subinhibitory concentrations for Gardnerella vaginalis and Mobiluncus curtisii to vaginal epithelial cells (VEC). STUDY DESIGN: Bacterial strains 14C- and or 3H-labeled were tested for adherence and competition to binding sites in VECs before and after treatment at sub-MIC with cetyltrimethylammonium naproxenate. RESULTS: In control tests of adherence, G. vaginalis and M. curtisii had their maximal adhesion at pH 5.4, L. acidophilus at pH 4.4. Preincubation of G. vaginalis and M. curtisii with cetyltrimethylammonium naproxenate 2.5 mg/mL (subinhibitory concentration) at pH 5.4 reduced adherence to VECs respectively by 48.3% and 34.1%. The same treatment of L. acidophilus showed no statistically significant difference. Treatment of VECs alone did not modify adherence. Competition tests between L. acidophilus and G. vaginalis and between L. acidophilus and M. curtisii showed that, in small quantities, L. acidophilus could compete with G. vaginalis and M. curtisii for binding sites in VECs at pH 4.4, when pretreated with cetyltrimethylammonium naproxenate. At a higher pH (4.8 and 5.4), L. acidophilus in higher quantities did not compete for binding sites occupied by G. vaginalis and M. curtisii. CONCLUSIONS: Cetyltrimethylammonium naproxenate at subinhibitory concentrations modifies the adhesiveness of G. vaginalis and M. curtisii to VECs, reducing it by 48.3% and 34.1%, respectively. Adhesion of L. acidophilus to VECs is not impaired by pretreatment with cetyltrimethylammonium naproxenate at pH 4.4, even if they are in low number and compete for binding sites against pathogens. At higher pH levels, L. acidophilus did not compete for binding sites occupied by G. vaginalis and M. curtisii.
