RESUMEN
Ulipristal acetate (UPA) is an effective drug for the treatment of symptomatic uterine fibroids. The drug is highly effective in controlling bleeding control and in the recovery of anemia. Here, we report the case of a woman with severe menorrhagia due to a uterine fibroid and with concomitant pulmonary embolism, a serious life-threatening condition. UPA was shown to be effective in reducing fibroid volume and controlling symptoms, without worsening the underlying embolic disease. No adverse events were observed, and the patient has completely recovered.
RESUMEN
In the present work, the aggregation behavior of polymeric particles possessing different glass transition temperatures (i.e., different "softnesses") has been studied to shed light on the interplay between aggregation and coalescence. In particular, the time evolution of the clusters hydrodynamic and gyration radii as well as of their structure factor has been monitored. With the help of an ad hoc developed deterministic model, based on population balance equations, it was possible to establish a link between the experimentally obtained light scattering data and the predicted particle size distribution. The simplicity of the model, involving one single adjustable parameter based on the coalescence characteristic time, allowed us to obtain a good accordance between simulations and experimental results with little computational effort.
RESUMEN
BACKGROUND: Despite it is accepted that acne is mostly caused by an hyper-responsiveness of the pilo-sebaceous unit to normal circulating androgen hormones, in a few patients, especially women, acneic lesions can be associated with increased serum androgen levels (hyperandrogenism), of which polycystic ovary syndrome (PCOS) is the most common cause. In women with acne and proven PCOS therapy with estroprogestins (EPs) can be an excellent option. OBJECTIVE: The aim of the study was to assess the effects of two estroprogestins (EPs), ethinyl-estradiol (EE) 30 mcg/drospirenone (DRSP) 3 mg, and ethinyl-estradiol (EE) 30 mcg/chlormadinone acetate (CMA) 2 mg, both on increased serum androgen levels and on several skin parameters in women affected by mild to severe acne and polycystic ovary syndrome (PCOS). METHODS: Fifty-nine women were randomized to receive EE/DRSP (n = 32) or EE/CMA (n = 27) for six months. Evaluation of serum androgen levels, grading of acne and hirsutism (respectively with Pillsbury and Ferriman-Gallwey score) and non-invasive assessment of skin hydration, transepidermal water loss (TEWL) and skin homogeneity were performed at baseline, at 3 and 6 months (end of treatment). RESULTS: Both treatments were well tolerated and showed a significant improvement of skin and hormonal parameters, although EE/DRSP showed a more potent effect on acne and seborrhea. CONCLUSIONS: Estroprogestins represent an effective and safe treatment in women with acne and polycystic ovary syndrome (PCOS). Nevertheless, the combination EE 30 mcg/DRSP 3 mg appears to be a more potent therapeutic option.

AIM: evaluate the efficacy of an estroprogestin EP containing 20 mcg ethinilestradiol (EE) and 3 mg drospirenone (DRSP) in the treatment of hyperandrogenism. METHODS: In this study, twenty hyperandrogenic patients were treated with an EP containing EE 20 mcg and DRSP 3 mg in 24+4 regimen for three months. Skin evaluation was performed both quantitatively and qualitatively. RESULTS AND CONCLUSION: This EP combination showed, after a short-term treatment (three months) to decrease significantly seborrhea, acne, and circulating androgens (testosterone, deidroepiandrosterone sulphate, and androstenedione), while increased sex hormone binding globulin levels. Moreover, this EE 20 mcg/DRSP 3mg EP combination changed some parameters of skin quality, increasing corneometry (a parameter related to skin hydration), and reduced trans epidermal water loss (TEWL, a parameter related to skin evaporation), and erythema (a parameter related to skin inflammation). These results could be taken into account in individualizing the treatment of hyperandrogenic patients.

Progestins are a group of different compounds sharing the ability to induce secretory changes on a endometrium pretreated with estrogen, while they are different in some abilities, for example the interaction with receptors other than progestin receptor, as androgenic or mineralocorticoid receptor. Some progestins have antiandrogenic properties and are used in treating hyperandrogenic manifestations (seborrhea, acne, hirsutism). The different clinical pharmacology of the various progestins is the basis for an individualized treatment in different clinical conditions. Key words.

AIM: This study evaluated hormonal and skin effects in hyperandrogenic women of an oral estroprogestin (EP) association containing ethynilestradiol 30 mcg plus drospirenone 3 mg. METHODS: Thirty two women with signs and symptoms of hyperandrogenism (seborrhea, acne, increased hair); hormonal assessment (follicle-stimulating hormone, [FSH]; luteinizing hormone, LH; 17-hydroxi-progesterone, 17OHP; androstenedione, A, testosterone, T; dehydroepiandrosterone sulfate, DHEAS; sex hormone binding globulin, [SHBG]; Free Androgen Index [FAI, Tx100/SHBG] was performed before the start of treatment, and after 3 and 6 months of administration of EP. The impact on seborrhea, acne, and hair pattern (Ferriman-Gallwey score) was assessed, and, by non-invasive technique, hydration, water transpiration, and homogeneity of the skin were evaluated. RESULTS: Treatment with this EP for 6 months decreased significantly circulating androgen levels (A, T, DHEAS) and FAI, and increased SHBG levels, also reducing seborrhea, acne and hirsutism. Moreover, EE/DRSP increased hydration and improved overall appearance of skin surface (homogeneity). CONCLUSION: Treatment with EE 30 mcg+DRSP 3 mg improves hormonal pattern and skin appearance in hyperandrogenic patients, potentially with subsequent, beneficial effects on quality of life of these women.

We studied the expression of adhesion molecules affecting recirculation and homing on peripheral blood CD4(+) T cells of patients with systemic sclerosis (SSc), in order to evaluate whether the distribution of tissue targeted subsets could reflect the participation of internal organs or the extent of cutaneous involvement [i.e. limited cutaneous (lc) and diffuse cutaneous (dc)]. Peripheral blood mononuclear cells (PBMC) from 51 patients with SSc and 19 sex- and age-matched controls were investigated by cytofluorimetric analysis for lymphocyte subpopulations carrying the following surface molecules: CD3, CD4, CLA, alpha4beta7 and alpha4beta1. Standard routine biochemistry and clinical examinations were also performed in all patients. We found that both alpha4beta1(+) and alpha4beta7(+) cells within the CD4(+) T cell population were significantly increased, while CLA(+) CD4(+) T cells were significantly reduced in SSc, compared to healthy donors. Significantly lower absolute numbers of alpha4beta7(+) cells were found in lc- compared to dc-SSc. Patients with oesophageal involvement had high numbers of alpha4beta7(+) cells, while those with nephritis also showed low levels of CLA(+) cells. Lung involvement was related directly to alpha4beta1(+) cell numbers and inversely to alpha4beta7(+) CD4 cell numbers. Taken together, our findings demonstrate that distinct CD4(+) T cell populations with selective homing properties show changes from normal distribution in SSc, and such changes are related to clinical expression and organ involvement in the course of the disease.

Amisulpride is an atypical antipsychotic with selective affinity for dopamine D2/3 receptors. In this long-term, open, randomised, multicentre trial, patients with chronic or subchronic schizophrenia received amisulpride (n =370) or haloperidol (n = 118) for 12 months. Dosage regimens were flexible (amisulpride 200-800 mg/day, haloperidol 5-20 mg/day). Improvement in mean Brief Psychiatric Rating Scale total score was significantly greater for amisulpride than haloperidol (17.0 versus 12.8, P = 0.01). Positive symptoms (Positive and Negative Syndrome Scale [PANSS] positive) improved in a similar way in each group but amisulpride caused a significantly better improvement in negative symptoms (PANSS negative) (7.1 versus 3.7, P < 0.0001). Improvements in Global Assessment of Functioning (GAF) and Quality of Life Scale (QLS) scores were also significantly greater in the amisulpride group (GAF -20.1 versus -13.6, P = 0.001; QLS -0.64 versus -0.30, P = 0.02). Adverse events were mainly psychiatric in nature, and occurred with similar frequency in each group (amisulpride 254/370, 69%; haloperidol 82/118, 70%). Extrapyramidal symptoms were more frequent for haloperidol (48/118, 41% versus 96/370, 26% for amisulpride), leading to a greater requirement for antiparkinsonian medication (haloperidol 66/118, 56% versus amisulpride 118/370, 32%). Haloperidol significantly aggravated parkinsonism, akathisia and involuntary movement compared to amisulpride. The overall incidence of endocrine events was comparable between groups (4% for amisulpride, 3% for haloperidol). Maintenance of efficacy was comparable in both treatment groups; 59% of amisulpride patients and 55% of haloperidol patients improved after 1 month of therapy remained improved throughout the study period. Amisulpride is effective following flexible long-term administration and significantly improves social functioning and quality of life.

BACKGROUND: The morphologic capillary microscopy (capillaroscopy) pattern of acrocyanosis is characterized by hemorrhages, pericapillary edema, and widened capillaries. These findings can result in a difficult differential diagnosis with systemic sclerosis (SSc). OBJECTIVE: We sought to quantify the characteristics of the capillaroscopy pattern that distinguishes patients with acrocyanosis from patients with SSc and control subjects. METHODS: A videomicroscope with fiberoptic illumination and personal computer-based image processing was used to measure capillary density, giant capillaries, loop width, and arterial and venous limbs in 10 patients with acrocyanosis, 10 patients with SSc, and 10 healthy control subjects. RESULTS: Acrocyanotic patients differed in every quantitative parameter both from control subjects and patients with SSc. In particular, capillary density, which was reduced compared with that of control subjects, was much higher than that of patients with SSc: one giant capillary per finger was observed in 2 patients with acrocyanosis, whereas more than 2 giant capillaries per finger were observed in each patient with SSc. CONCLUSION: These differences may aid in making the distinction between the capillaroscopy patterns in acrocyanosis and SSc.

Pharmacotherapy remains the main medical means of treating depression, and constant progress during recent years has led to the present availability of many effective and well tolerated drugs. Some essential conditions should be present for optimum therapeutic efficacy. The appropriate indications should be precisely defined. The most active and best tolerated product should be chosen for each patient. The medical treatment should be associated with psychotherapy. Finally, the patient should be followed-up with regard to restoration of his relations with his family, social and professional groups. Much progress remains to be made. The most important are better knowledge of the mechanisms of action of antidepressants and of the pathophysiopsychological mechanisms of depression. Some rare cases of very severe depression, either unresponsive to medical treatment or when such treatment is contraindicated, still require the use of electroconvulsive therapy. Light therapy is used in seasonal affective disorder.

BACKGROUND AND AIM: A study was performed of the perioperative systemic effects of a recent zoned chemotherapy technique administered in conditions of extreme acidosis, hypoxia and modern hypotension. EXPERIMENTAL DESIGN: a prospective analysis of the changes compared to basal values using Student's t test for paired data. SETTING: Operating theatres and Recovery room. PATIENTS OR PARTICIPANTS: A population of 16 consenting patients suffering from abdominal or pelvic neoplasms, ASA 1-3, recruited according to the parameters suggested by the international literature. SURGERY: central venous catheter, radial arterial catheter, open catheter of the e.v. femoral artery, general anesthesia using isoflurane. Tests performed: Blood gas analysis of systemic arteries, abdominal veins and the superior vena cava at times preceding clamping (T0) and 7 and 14 mins after the start, at declamping, on reawakening from anesthesia and 30 and 60 mins afterwards (T1, T2, T3, T4, T5, T6). Serial evaluation of activated coagulation time. RESULTS: Mean 25% reduction of neoplastic mass, systemic arterial and venous pH diminished at T1 and T2, but more marked and transient at T3; district venous pH significantly diminished during entire Stop-Flow. Systemic PaO2 increased throughout method (SaO2 > 98%). PaO2 in the superior vena cava recorded significantly higher intraoperative values compared to basal and postoperative levels, no major differences found at time T3. SaO2 showed statistically significant differences between the superior vena cava and the abdominal distrist at both T 1 (p 0.0002) and T2 (p 0.004). No toxic effects due to NPS were observed. CONCLUSIONS: This is a safe technique but not without risks, which requires considerable anesthesiological commitment.

We describe the clinical and laboratory findings of a young man with mycosis fungoides. The disease was associated, since the early stages, with autoimmune purpura. Interferon alfa (IFN-alpha) administration improved this patient's condition, both the purpuric eruption and patchy cutaneous lesions, thus suggesting T-cell abnormalities may be responsible for the development of the disease.

The clinical properties of amineptine, a mainly dopaminergic antidepressant, were assessed in a double-blind controlled study involving patients fulfilling Diagnostic and Statistical Manual of Mental Disorders (DSM-III) criteria for unipolar depression. The aim was to determine how relapses could be prevented in this frequently recessing disorder. The study was a two-phase, 12-month, multicentre trial of patients suffering from major depression or dysthymia, diagnosed using DSM-III criteria and evaluated on the Montgomery-Asberg Depression Rating Scale and the Mood, Anxiety, Retardation, Danger scale. Phase I was an open-label 3-month period, with the patients being given 200 mg amineptine per day. The second, 9-month period was a placebo-controlled prophylactic phase. A total of 458 patients were initially included in the study. Of the 376 who completed phase I, 303 (66%) were responders; 284 entered the prophylactic study, randomly assigned to two groups. Of the 134 patients in the placebo group who completed phase II, 25 (18.7%) suffered a relapse, compared with nine out of the 136 (6.6%) in the amineptine group. After resolution of an acute episode of major depression or dysthymia, long-term antidepressant therapy with amineptine significantly reduced the relapse rate.

OBJECTIVE: To evaluate the efficacy of one-day, intermittent, monthly prophylaxis with 400 mg itraconazole in the management of recurrent vulvovaginal candidiasis. STUDY DESIGN: In a randomized trial, 57 patients and 57 controls with recurrent vulvovaginal candidiasis were assigned either to receive one-day monthly itraconazole prophylaxis for six months or no treatment. Clinical and mycologic evaluations were carried out 3, 6 and 12 months after enrollment. RESULTS: During the first six months of follow-up, the rate of symptomatic recurrences was 36.4% (20/55) among the treated women and 64.2% (34/53) in the controls. The mean time +/- SEM to symptomatic recurrence was 149 +/- 6 days among patients receiving prophylaxis and 120 +/- 6 days in the controls (P = .003 by log-rank test). These differences disappeared almost completely after the cessation of intermittent prophylaxis. In fact, the proportion of patients still asymptomatic after one year of follow-up was 38.9% (21/54) among treated women and 28.8% (15/53) in the controls (P = .83 by Fisher's exact test). CONCLUSION: One-day monthly, intermittent itraconazole prophylaxis reduced the rate of recurrence in patients with recurrent vulvovaginal candidiasis, but the beneficial effect of itraconazole was lost within a few months after cessation of prophylaxis.

OBJECTIVE: Our purpose was to evaluate the prevalence of symptomatic yeast vaginitis caused by non-albicans species among patients attending a vaginitis clinic over an 8-year period. STUDY DESIGN: A retrospective study of 1263 patients with symptomatic yeast vaginitis confirmed by culture techniques was performed. RESULTS: The prevalence of symptomatic fungal vaginitis caused by non-albicans species increased from 9.9% (10/101) in 1988 to 17.2% (36/209) in 1995 (chi 2 for trend = 9.33, p = 0.002). Non-albicans species were found more frequently in known human immunodeficiency virus-seropositive patients (23/102 vs 143/1161, odds ratio 2.07, 95% confidence interval 1.2 to 3.46) than in seronegative subjects or subjects of unknown status for the virus. Recurrent vaginal candidiasis was an additional risk factor for vaginitis caused by non-albicans species (odds ratio 2.47, 95% confidence interval 1.72 to 3.52). The increase in non-albicans isolates during the study period was confirmed in stratified analysis and in the subgroup of self-referred patients with no history of either human immunodeficiency virus infection or recurrent vaginal candidiasis. CONCLUSION: The prevalence of fungal vaginitis caused by non-albicans species has increased sharply in the setting of a vaginitis clinic. The characteristics of risk factors suggest that fungal cultures should be done routinely in human immunodeficiency virus-seropositive subjects with suspected vaginal candidiasis and in patients with recurrent vaginal infection.

Schnitzler syndrome is a rare condition characterized by chronic non-pruritic urticaria, recurrent fever, bone pain, osteocondensation, and monoclonal IgM gammopathy without features of lymphoproliferative disease. We describe the case of a 44-year-old man with an 8-year history of bone pain with hyperostosis and a 5-year history of chronic non-pruritic urticaria, associated with fever, hyperleukocytosis, hepatomegaly, serum monoclonal IgM-kappa. Systemic treatment with steroids was effective against bone pain but was ineffective in controlling the urticaria. We also review 35 cases. No adequate treatment has yet been found. The pathogenesis is unclear and the role of the IgM component in the induction of urticaria has not been established.
