Safety profile of the adjuvanted recombinant zoster vaccine: Pooled analysis of two large randomised phase 3 trials

Background

The ZOE-50 (NCT01165177) and ZOE-70 (NCT01165229) phase 3 clinical trials showed that the adjuvanted recombinant zoster vaccine (RZV) was ≥90% efficacious in preventing herpes zoster in adults. Here we present a comprehensive overview of the safety data from these studies.

Abortion policies and practices in Chile: ambiguities and dilemmas

Abortion is not legal in Chile even to save the woman's life or health. This situation creates serious dilemmas and vulnerabilities for both women and medical practitioners. Abortion incidence has probably decreased since 1990, when data were last studied, due to increased use of contraception and lower fertility, and deaths and complication rates have fallen as well. Misoprostol is available, but Chilean hospitals are still using D&C for incomplete abortions. Although Chilean medical professionals should by law report illegal abortions to the authorities, less than 1% of women in hospital with abortion complications are reported. There are two loopholes, one legal, one clinical. "Interruption of pregnancy" after 22 weeks of pregnancy is legal for medical reasons; this may save some women's lives but can also force prolongation of health-threatening pregnancies. Catholic clinical guidelines define interventions solely aimed at saving the woman's life, even if the fetus dies, not as abortion but "indirect abortion" and permissible. Since 1989, three bills to liberalise the law on therapeutic grounds have been unsuccessful. The political climate is not favourable to changing the law. Conservatives have also not succeeded in making the law more punitive, while the governing centre-left coalition is divided and the associated political risks are considerable.     

Single fiber electromyography of extraocular muscles: A sensitive method for the diagnosis of ocular myasthenia gravis

We performed single fiber electromyography (SFEMG) in the superior rectus and levator palpebralis (SR-LP) muscles of 17 patients with pure ocular myasthenia gravis (MG) and 9 controls. Thirteen patients were also assessed with SFEMG in the orbicularis oculi (OO) muscle. All the MG patients but none of the control subjects showed abnormal SFEMG jitter in the SR-LP muscles. On the other hand, only 62% of the MG patients had abnormal SFEMG jitter in the OO muscle. The procedure was well tolerated by the patients, and complications were minor. We conclude that SFEMG of the SR–LP muscles is a safe and highly sensitive technique for the diagnosis of ocular MG. © 1995 John Wiley & Sons, Inc.     

Metabolic and hormonal blood flow modeling in patients with coronary heart disease: In vitro and clinical study

The blood flow pattern investigations are of great importance in coronary blood flow destabilization pathogenesis understanding, and consequently in acute coronary event (ACE) risk stratification in patients with coronary heart disease. The aim of the study was to research the principal hormonal and metabolic blood flow regulative aspects and its structure in patients with ischemic heart disease and the contribution to cumulative ACE risk.A total of 182 patients with stable angina pectoris were included in the prospective study (2000–2006). Complex clinical examination, biochemical tests and blood tests were performed. Whole-blood (WB) viscosity, erythrocyte aggregation and deformation ability, WB suspension stability, and initial erythrocytes disaggregation parameter were studied. Dynamic characteristics of blood flow were obtained in the experiment.Received results allow marking the principle components of blood flow pattern with proven high prognostic value of ACE in patients with ischemic heart disease. ACE risk stratification program was developed.     

IL-6 and IL-10 promoter gene polymorphisms do not associate with the susceptibility for multiple myeloma

Multiple myeloma (MM) is a plasma cell malignancy characterised by bone marrow infiltration and the presence of a monoclonal protein in serum and/or urine. Interleukin-6 (IL-6) has been identified as one of the most important cytokines that contributes to myeloma cell survival and proliferation. Recent investigations suggest involvement of another cytokine, IL-10, in the activation of MM cells. The present study aimed to determine whether there is an association between the polymorphic features located within the promoter regions of IL-6 and IL-10 genes and progression the disease. IL-6 (-174 G/C) and IL-10 (-1082 A/G, -819 C/T, -592 A/C) promoter single nucleotide polymorphisms (SNPs) were determined by PCR-SSP technique using commercial primers. Our single centre results were compared with the data from literature and combined in cumulative analysis employing the Mantel-Haenszel method. In univariate analysis, only IL-10 ACC genotype tended to prevail in our (Polish) group of patients. None of IL-6 genotypes or IL-10 (-1082) alleles was found to associate with MM disease either in our single centre or in cumulative study. Among patients who died within 36 months of diagnosis, a significant prevalence (P < 0.05) of IL-6 heterozygous cases as opposed to IL-6 homozygotes was observed. IL-6 and IL-10 promoter gene polymorphisms were not found to associate with the susceptibility to the development of MM. However, the IL-6 polymorphic features appeared as factors that might affect the survival of MM patients. The latter observation warrants further study.     

Assessment of intrafamilial clinical variability of poikiloderma with neutropenia by a 10-year follow-up of three affected siblings

Clericuzio-type poikiloderma with neutropenia is a well-defined nosological entity, but despite a remarkable number of clinical reports, no long term follow-up data has been presented to date regarding patients with this rare condition.Here we describe the results of clinical follow-up of three siblings, one male (Patient 1) and two females (Patients 2 and 3), subsequent to their first clinical and then molecular diagnosis of Clericuzio-type poikiloderma with neutropenia syndrome due to mutation of USB1gene. Patient 1 always expressed the most severe phenotype, while patients 2 and 3 showed an intermediate and mild phenotype, respectively, as observed since their first clinical evaluation. None of the patients developed skin cancer and/or myelodysplastic disorders considering the peripheral haematological findings. Lens opacity, never reported before, was found in two of the three patients.The long term follow-up observations confirm the stability over time of the pronounced intra-familial heterogeneity of clinical manifestations observed prior to and upon molecular diagnosis. We conclude that prolonged follow-up is an adjunct tool to monitor intra-familial variability of PN clinical spectrum which may favour surveillance of more serious complications of the disease among siblings, when a patient-specific clinical expressivity is present.
