Iron Deficiency in Menstruating Adult Women: Much More than Anemia.

Iron deficiency anemia (IDA) is highly prevalent in women of child-bearing age. However, their nonhematological symptoms have been overlooked. This study aims to analyze the nonhematological features and symptoms of IDA in a group of women of reproductive age and the changes occurred during iron therapy.

Femtosecond-Assisted Big Bubble: A Feasibility Study.

Purpose: To evaluate the feasibility of femtosecond laser-assisted (FA) tunnel creation as a pretreatment for creating a big bubble (BB) to pneumo-dissect the corneal stroma from Descemet membrane.

Methods: Five human cadaver eyes received pretreatment using a femtosecond laser. An intrastromal tunnel, along with a side cut, was achieved using customized femtosecond corneal disruption (custom mask).

Sideroblastic anemia: functional study of two novel missense mutations in ALAS2.

Background: X-linked sideroblastic anemia (XLSA) is a disorder characterized by decreased heme synthesis and mitochondrial iron overload with ringed sideroblasts in bone marrow. XLSA is caused by mutations in the erythroid-specific gene coding 5-aminolevulinate synthase (ALAS2). Anemia in XLSA is extremely variable, characteristically microcytic and hypochromic with poikilocytosis, and the red blood cell distribution width is increased and prominent dimorphism of the red cell population.

Characterisation of a household norovirus outbreak occurred in Valencia (Spain).

Background: Human noroviruses (NoVs) are the main cause of non-bacterial gastroenteritis worldwide. Several studies have linked human susceptibility to NoVs with the expression of histo-blood group antigens (HBGAs). In January 2012, a NoV gastroenteritis outbreak affected a household in Valencia, Spain, and the personal susceptibility to NoV was investigated.

Vitamin B12 and folate levels increase during treatment of iron deficiency anaemia in young adult woman.

Introduction: The relationship between iron deficiency and vitamin B12 and folate was recognized several decades ago. Combined deficiency is important in clinical practice owing to its relationship with malabsorption syndromes. By contrast, iron deficiency and low levels of serum vitamin B12 with normal metabolic markers were often found mostly in young adults.

Norovirus infections and seroprevalence of genotype GII.4-specific antibodies in a Spanish population.

Genotype II.4 noroviruses (NoVs) are a leading cause of epidemic acute gastroenteritis in children and adults worldwide. The prevalence of different NoV genotypes causing outbreaks and sporadic cases of acute gastroenteritis in the region of Valencia, Spain, during a 4-year period (2008-11) was investigated.

Microcytic anemia in a pregnant woman: beyond iron deficiency.

Sideroblastic anemias are a heterogeneous group of disorders characterized by anemia of varying severity and the presence of ringed sideroblasts in bone marrow. The most common form of inherited sideroblastic anemia is X-linked sideroblastic anemia (XLSA). In many XLSA patients, anemia responds variably to supplementation with pyridoxine (vitamin B6).

Novel group A rotavirus G8 P[1] as primary cause of an ovine diarrheic syndrome outbreak in weaned lambs.

Rotavirus is a worldwide major cause of diarrhea outbreaks in neonatal ruminants. An outbreak of ovine diarrheic syndrome (ODS) in 50-75 days-old lambs (weaned lambs) is described. Fecal immunochromatography and intestinal immunohistochemistry for rotavirus group A were performed.

Seroprevalence of Aichi virus in a Spanish population from 2007 to 2008.

Viruses are among the most common causes of acute gastroenteritis. In recent years, new viruses causing outbreaks of acute gastroenteritis have been described. Among these, Aichi virus was identified in Japan in 1989.

[Predominance of G9 rotavirus in Valencia and Castellón between 2005 and 2007].

Introduction: Rotavirus is the leading cause of acute gastroenteritis in young children worldwide. Effective vaccines to prevent rotavirus infections are currently available, although their clinical use is still limited, and rotavirus still causes many episodes of infantile gastroenteritis, mainly during the winter seasons.

Objective: To characterise G (VP7) and P (VP4) genotypes of rotaviruses causing acute gastroenteritis in children and to determine the prevalence of genotype G9 rotavirus in three public health areas in the provinces of Valencia and Castellon.

Enteric calicivirus and rotavirus infections in domestic pigs.

We report the prevalence of rotavirus and calicivirus infections, along with their respective association with diarrhoea in the porcine population of the region of northern Spain. A total of 221 samples were collected at random from different farms in the region and from the main slaughterhouse facility in the city of Zaragoza. Faecal samples were scored as diarrhoeic or normal and grouped into five groups to match general farm management and age criteria: group I (suckling 0-4 weeks), group II (weaning >4-8 weeks), group III (transition >8-16 weeks), group IV (fattening >16-24 weeks) and group V (adults >24 weeks).

Analysis of factors affecting PBPC collection in low-weight children with malignant disorders.

Background: PBPC collection in children weighing
Methods: Data from 88 leukaphereses performed in 45 children were analyzed, including pre-apheresis CD34(+) cell count, COBE Spectra software (version 4.

Identification of factors associated with poor peripheral blood progenitor cell mobilization in Hodgkin's disease.

Background And Objectives: Although the use of drugs which damage stem cells is common in patients with Hodgkin's disease (HD), factors affecting peripheral blood progenitor cell (PBPC) mobilization have not been clearly established in this group of patients. The aim of this study was to identify factors associated with poor PBPC mobilization in patients with HD.

Design And Methods: In order to address this issue we have evaluated in 54 patients with HD mobilized with G-CSF alone the following factors: sex, age, histologic subtype, B symptoms at diagnosis, status of remission, previous chemotherapy and radiotherapy, interval from diagnosis and last chemotherapy cycle to harvest, and dose of G-CSF.

Treatment with plasmapheresis and intravenous immunoglobulin in pregnancies complicated with anti-PP1Pk or anti-K immunization: a report of two patients.

Background And Objectives: In addition to anti-D alloantibody, other antibodies such as anti-K antibody and anti-PP1Pk antibody have been reported to cause severe haemolytic disease of the newborn (HDN). HDN caused by anti-K results not only from destruction of red cells but also from suppression of erythropoiesis. Anti-PP1Pk has been associated with abortion early in pregnancy.

Long-term follow-up in patients treated with Mini-BEAM as salvage therapy for relapsed or refractory Hodgkin's disease.

Several studies have focused on investigation of the optimal salvage regimen to induce maximum response before autologous stem cell transplantation (ASCT) in patients with relapsed or refractory Hodgkin's disease (HD). However, in most of these studies, the follow-up is relatively short. In the present study, we report on long-term results of 55 consecutive patients with HD who received Mini-BEAM [BCNU (carmustine), etoposide, cytarabine, melphalan] as salvage therapy before ASCT.

Sweet's syndrome and accelerated phase of chronic myelogenous leukemia.

Sweet's syndrome is a neutrophilic dermatosis characterized clinically by raised, erythematous, tender lesions on the face, neck, upper thorax and extremities. Several diseases have been associated with this entity. We report a case of Sweet's syndrome associated with chronic myelogenous leukemia: a 48-year-old woman who developed recurrent skin lesions 3 years after the diagnosis of chronic myelogenous leukemia.

Salvage chemotherapy with mini-BEAM for relapsed or refractory Hodgkin's disease prior to autologous peripheral blood stem cell transplantation.

Background And Objective: High-dose chemotherapy and autologous bone marrow transplantation (ABMT) has become the standard approach for most patients with relapsed or refractory Hodgkin's disease. Disease status at transplant has been correlated with outcome following ABMT. In light of this, we employ mini-BEAM (BCNU, etoposide, cytarabine and melphalan) salvage therapy in order to achieve a state of minimal residual disease prior to transplantation.
