  • Multidisciplinary management in Merkel cell carcinoma.
  • Matkowski R, Lata E, Zietek M, Halon A, Forgacz J, Szynglarewicz B.Author information Department of Oncology, Division of Oncological Surgery, Wroclaw Medical University , Plac Hirszfelda 12, Wroclaw , Poland.AbstractHerein, the authors describe the experience with the treatment of Merkel cell carcinoma (MCC) and review the literature regarding MCC treatment regimens. Nine patients underwent treatment due to stage I, II, or III MCC. The median follow up was 39 months. In five cases, tumors were excised with skin margins of >2 cm, and skin margins were <2 cm in four patients. Local adjuvant radiotherapy (RT) was given to four patients, while three patients underwent local lymphadenectomy (LAD). Local recurrence occurred in four patients who did not undergo RT (among them three patients had excision margins <2 cm) after a mean time of 9 months. Despite retreatment, two of those patients developed metastases. Recurrence-free survival after primary therapy was achieved: (a) in three patients with stage I and II MCC treated surgically with excision margins <2 cm combined with RT or wide excision >2 cm alone and (b) in two patients with stage III MCC treated with wide excision and LAD combined with local and regional RT. A review of the literature supports the following recommendations: (a) excision with adequate margins combined with RT; (b) LAD with regional RT in cases of lymph node involvement; and (c) sentinel lymph node biopsy in patients without clinically suspicious lymph nodes.

  • Prenatal diagnosis of leukocyte adhesion deficiency type-1 (five cases from iran with two new mutations).
  • Esmaeili B, Ghadami M, Fazlollahi MR, Niroomanesh S, Atarod L, Chavoshzadeh Z, Moradi Z, Alizadeh Z, Pourpak Z.Author information Immunology, Asthma and Allergy Research Institute, Tehran University of Medical Sciences, Tehran, Iran. esmaeili.behnaz@yahoo.com.AbstractLeukocyte adhesion deficiency type-1(LAD-1) is one of the immunodeficiency autosomal recessive diseases that results from mutation in integrin, beta 2 (complement component 3 receptor 3 and 4 subunit) ITGB2 gene. The aim of this study was to investigate molecular prenatal diagnosis of LAD-1.Four pregnant women with five fetuses (one pregnancy was twin) with clinical and laboratory diagnosis of LAD-1 in their previous children were studied. The chorionic villus sampling (CVS) was obtained when mothers were in 10-12th weeks of gestation.Mutation analysis of ITGB2 gene for affected children revealed 3 misssense mutations (c.382G&gt;A, a novel mutation, c.2146G&gt;C, and c.715G&gt;A) and one splice site novel mutation (c.1877+2G&gt;A). All of Parents were heterozygous for these mutations. Consideration of affected gene regions for five CVS samples showed two homozygotes and one heterozygote for mutant allele and two homozygotes for normal allele. Interestingly, one of the twin fetuses was affected and another was normal. Briefly, two cases of CVS samples were affected and three cases of remained CVS samples were unaffected.This is the first report of prenatal diagnosis of LAD-1 from Iran with two new mutations that can be used for genetic and prenatal diagnosis for all patients suspected to LAD1 and can be helpful to prevent the birth of affected children with LAD-1. This abstract presented in the second international congress of Immunology, Asthma and Allergy, Tehran, Iran 2013.

Electronic address: liujx0324@sina.com.AbstractETHNOPHARMACOLOGICAL RELEVANCE: Salvia miltiorrhiza (SM, also known as DanShen) is one of the well-known widely used Chinese herbal medicines in clinical, containing phenolic compounds and potent antioxidant properties. Salvianolic acid A (SAA) is the most potent component of SM. A modern experimental strategy for treating myocardial ischemia is to induce neovascularization of the heart by the use of "angiogens", mediators that induce the formation of blood vessels, or angiogenesis. Studies demonstrated that coronary collateral vessels protect ischemic myocardium after coronary obstruction; therefore, we sought to examine whether SAA could stimulate myocardial angiogenesis.
