Acne Smart Club: An Educational Program for Patients with Acne

Objective: To evaluate adherence to therapy in acne patients using mobile phones and Short Message Service (SMS) to communicate. Methods: 160 patients were randomly assigned to two groups: the SMS group received 2 text messages twice a day for a period of 12 weeks; the control group did not receive any messages. Before and after 12 weeks, the following evaluations were performed in all patients: digital photographs, the Global Acne Grading System, the Dermatology Life Quality Index, the Cardiff Acne Disability Index, the doctor-patient relationship evaluated through the Patient-Doctor Depth-of-Relationship Scale, and the adherence to treatment evaluated by asking patients how many days a week they had followed the therapy. For statistical analysis we used Student's t test. Results: The SMS group had a better improvement of all parameters compared to the control group. Conclusion: Adherence and compliance are higher for patients who are included in a strategy of control. © 2014 S. Karger AG, Basel

Langerhans' cell histiocytosis of the vulva: The use of photodynamic therapy

Background: The evaluation of possible efficacy of Photodynamic Therapy (PDT) in a rare condition of vulvar Langerhans' cell histiocytosis (LCH), in a 43-years-old women with one year history of pruritic vulvar lesions. Main observations: After a cycle of 5 sessions of PDT, with aminolevulinic acid (ALA) in low percentage (5%), the patient reported an improvement of lesions, and an high improvement of local symptoms, with a significant reduction of itch and pain. Conclusions: Our case confirms this single experience of literature for the treatment of vulvar LCH by PDT, with an improvement of disease's symptoms, and can suggest the use of PDT for this rare and untreated disease

Assessment of capillary volumetric blood microsampling for the analysis of central nervous system drugs and metabolites

Therapeutic drug monitoring (TDM) is an important tool for correlating the administered drug dose to drug and metabolite concentrations in the body and to therapeutic and adverse effects. In the case of treatment with drugs active on the central nervous system (CNS), frequent TDM becomes really useful, especially for patient compliance checking and for therapy optimisation. The selective serotonin reuptake inhibitors (SSRIs) fluoxetine and sertraline, chosen as target compounds for this study, are two antidepressants mainly used for major depression, but also for obsessive-compulsive disorder associated with neurodegenerative diseases and for eating disorders. Microsampling approaches can be used to make TDM patient-friendly, by means of minimally invasive fingerpricking instead of classic invasive venipuncture. In this study, an innovative volumetric microsampling approach based on the use of hemaPEN technology is proposed to simultaneously obtain four identical dried whole blood microsamples by means of a single capillary sampling. The developed strategy shows significant advantages in terms of blood collection and storage, fast and feasible extraction procedure and sensitive LC-MS/MS analysis, also providing satisfactory validation results (extraction yield >81%, RSD <12.0%, and <6.3% loss in analyte stability after 3 months). The proposed methodology has proven to be sound and reliable for application to the TDM of psychiatric patients treated with antidepressant drugs such as fluoxetine and sertraline. The original capillary volumetric microsampling procedure using hemaPEN has been demonstrated to be suitable for the accurate sampling of capillary whole blood, in order to be successfully exploited in self- and home-sampling procedures in future and to pave the way for precision medicine approaches for the treatment of CNS disorders

Role of Notch2 pathway in mature B cell malignancies

In recent decades, the Notch pathway has been characterized as a key regulatory signaling of cell-fate decisions evolutionarily conserved in many organisms and different tissues during lifespan. At the same time, many studies suggest a link between alterations of this signaling and tumor genesis or progression. In lymphopoiesis, the Notch pathway plays a fundamental role in the correct differentiation of T and B cells, but its deregulated activity leads to leukemic onset and evolution. Notch and its ligands Delta/Jagged exhibit a pivotal role in the crosstalk between leukemic cells and their environment. This review is focused in particular on Notch2 receptor activity. Members of Notch2 pathway have been reported to be mutated in Chronic Lymphocytic Leukemia (CLL), Splenic Marginal Zone Lymphoma (SMZL) and Nodal Marginal Zone Lymphoma (NMZL). CLL is a B cell malignancy in which leukemic clones establish supportive crosstalk with non-malignant cells of the tumor microenvironment to grow, survive, and resist even the new generation of drugs. SMZL and NMZL are indolent B cell neoplasms distinguished by a distinct pattern of dissemination. In SMZL leukemic cells affect mainly the spleen, bone marrow, and peripheral blood, while NMZL has a leading nodal distribution. Since Notch2 is involved in the commitment of leukemic cells to the marginal zone as a major regulator of B cell physiological differentiation, it is predominantly affected by the molecular lesions found in both SMZL and NMZL. In light of these findings, a better understanding of the Notch receptor family pathogenic role, in particular Notch2, is desirable because it is still incomplete, not only in the physiological development of B lymphocytes but also in leukemia progression and resistance. Several therapeutic strategies capable of interfering with Notch signaling, such as monoclonal antibodies, enzyme or complex inhibitors, are being analyzed. To avoid the unwanted multiple “on target” toxicity encountered during the systemic inhibition of Notch signaling, the study of an appropriate pharmaceutical formulation is a pressing need. This is why, to date, there are still no Notch-targeted therapies approved. An accurate analysis of the Notch pathway could be useful to drive the discovery of new therapeutic targets and the development of more effective therapies

A dietary supplement to reduce side effects of oral isotretinoin therapy in acne patients.

AIM: The purpose of the study was to analyze the potential capacity of a dietary supplement, based on gamma linolenic acid, vitamin E, vitamin C, beta-carotene, coenzyme Q10 and Vitis Vitifera, to reduce side effects, in particular the dry skin, erythema and desquamation, due to treatment with oral isotretinoin, and evaluate the ability of the product to increase adherence to therapy in patients with acne. METHODS: Forty-eight patients with nodular acne (32 females and 16 males) were randomly divided into 2 groups: 24 receveid isotretinoin therapy (20-30 mg/day) for 6 months associated to dietary supplement (twice a day), while the other 24 patients received only isotretinoin (20-30 mg/day) for 6 months. For all patients the degree of acne severity, through GAGS (Global Acne Grading System), the sebum production by Sebutape, the hydration by Corneometer and the erythema by Mexameter, were measured. We have also evaluated the adherence to treatment, asking to patients how many days a week they follow the therapy. RERSULTS: Patients treated with dietary supplement had lower side effects, with a less degree of erythema and dryness, and greater degree of hydration; a greater adherence to therapy was also reported. CONCLUSION: Thanks to antioxidant and moisturizing properties, the dietary supplement containing gamma linolenic acid, vitamin E, vitamin C, betacarotene, coenzyme Q10 and Vitis Vitifera, can be considered a useful supplement in the treatment and prevention of dry skin associated with the use of oral isotretinoin

An 81-Year-Old Man with a 6-Year History of Chronic Lymphocytic Leukemia Presenting with Disease Flare Following Ibrutinib Discontinuation

Patient: Male, 81-year-old Final Diagnosis: Chronic lymphocytic leukemia Symptoms: Fever Medication: — Clinical Procedure: — Specialty: Hematology Objective: Background: Case Report: Conclusions: Unusual clinical course Chronic lymphocytic leukemia (CLL) is a mature B-cell neoplasm and the most common leukemia in adults in Western countries. Novel agents, including BTK inhibitors and the BCL2 inhibitor venetoclax, have dramati-cally changed the treatment landscape. Moreover, a disease flare, characterized by sudden worsening of clinical symptoms, radiographic findings of rapidly worsening splenomegaly or lymphadenopathy, and laboratory changes (increased absolute lymphocyte count or lactate dehydrogenase), is a phenomenon described in up to 25% of patients with CLL after ibrutinib discontinuation. We describe a patient with CLL with disease flare after ibrutinib discontinuation due to disease progression and describe the subsequent management of vene-toclax initial treatment in the course of the disease flare. We describe the case of an 81-year-old man with a 6-year history of CLL who was treated with multiple lines of therapy and developed worsening of disease-related signs and symptoms with fever, marked increase of lym-phocyte count, acute worsening of renal function, and increase in lymph nodes and spleen size following ces-sation of targeted therapy with ibrutinib at the time of disease progression. There was subsequent overlap-ping of ibrutinib during the venetoclax dose escalation period to prevent disease flare recurrence. Our report highlights the problem of disease flare after ibrutinib discontinuation in order to avoid associated patient morbidity, underscoring the importance of awareness of this phenomenon and focusing on the addition of venetoclax at time of progression in ibrutinib-treated patients, as a temporary overlap strategy, to prevent disease flare

Knowledge of emergency management of avulsed teeth among Italian dentists-questionnaire study and next future perspectives

(1) Background: In Italy, about one fourth of all schoolchildren experience a trauma to the permanent dentition. Management of avulsion trauma is challenging and requires adherence to clinical protocols. The aim of this study was to investigate the management knowledge of avulsed teeth among Italian dentists and to promote the guidelines’ dissemination through the use of new social media. (2) Methods: The survey was carried out during the COVID-19 lockdown in Italy (March–May 2020). The questionnaire was sent anonymously to a total of 600 dentists. The questionnaire consisted of two parts. Part A—demographic and professional data and Part B—management of traumatic avulsion. (3) Results: The response rate was 50.6% and the mean fraction of correct responses was 0.524. Issues related to the therapeutic management of avulsed teeth were shown to be not well understood by the respondents. Professionals with qualifications in dentistry and those who declared to know the guidelines responded better, while other demographic and professional factors were insignificant. (4) Conclusions: Italian dentists’ knowledge of the management of avulsion trauma should be improved. Educational programs and campaigns must be undertaken to improve their awareness and adherence to the Italian and international guidelines

Desempenho de frangos de corte (22 a 42 dias) alimentados com dietas peletizadas contendo glicerina bruta.

A maior parte das rações produzidas para frangos de corte no Brasil são peletizadas. Como benefício deste processamento observa-se melhora na digestibilidade dos nutrientes, redução de contaminações por patógenos, bem como melhorias nas condições de transporte. Existem muitos aditivos umectantes que podem ser utilizados para melhorar o processo de peletização, contudo a glicerina além de ser um umectante eficiente (1) é um alimento energético que tem grande potencial de produção no país. Assim sendo, objetivou-se avaliar o desempenho de frangos de corte na fase final (22 a 42 dias) alimentados com rações peletizadas ou fareladas com a inclusão de níveis crescentes de glicerina bruta
