[Surgical management of incidental Meckel's diverticulum: the necessity to obtain the informed consent].

Surgical approach to the incidentally found Meckel's diverticulum (MD) is still source of debate: some support the systematic search and the surgical resection, others suggest to leave in situ the asymptomatic diverticulum. A wide literature review and some claims for malpractice referred to resection of diverticular formations (2 cases are described herein) allow us to deem that the removal of an asymptomatic MD may be an excess of surgical indication regarding an entity that cannot be defined as pathological for itself; anyway, the informed consent must be obtained before the incidental resection. The consent to the removal of MD must always be requested for laparotomies in which the surgeon forecasts the possibility to remove a diverticulum eventually found.

Multiple sclerosis in children under 10 years of age.

Despite the consistent amount of information accumulated in recent years on multiple sclerosis (MS) in childhood, many clinicians still view this condition as an exclusively young adult-onset disease and do not consider that it may occur and manifest even during infancy and pre-school age, suggesting that the number of MS cases in the paediatric age group may have been underestimated. Thus, the need to have practical parameters for therapeutic, counselling and educational purposes in such settings as caring for patients whose onset of disease is at very early ages may increasingly arise for practising clinicians. In addition, the clinical and radiographic criteria for the diagnosis of MS have not been validated in a paediatric MS population; accordingly, inclusion age at onset (such as for research purposes) is generally over 10 years.

A new promoter polymorphism in the alpha-1-antichymotrypsin gene is a disease modifier of Alzheimer's disease.

Increased levels of alpha-1-antichymotrypsin (ACT), a protease inhibitor and an acute phase protein, have been found in the brain and peripheral blood of patients with Alzheimer's disease (AD). Patients from northern Italy with a clinical diagnosis of probable AD, and patients with early onset AD (EOAD) from UK with AD neuropathological diagnosis were genotyped for a new polymorphism in the promoter region of the ACT gene which has been shown to affect ACT expression. A subset of patients with clinical AD from northern Italy was also followed up for 2 years and monitored for cognitive decline.

Carbon dioxide therapy: effects on skin irregularity and its use as a complement to liposuction.

For a successful conventional or superficial liposuction, it is necessary to consider the competence of the surgeon who is to administer the procedure necessary for this type of surgery as well as the physical and psychological evaluation of the determined patient. A poor result often is related to the persistence of adipose tissue irregularity in the form of fatty tissue accumulation. This complication, common to this type of surgery, has called for research to determine methods for its treatment.

Ctla4 and multiple sclerosis in the Italian population.

CTLA4 protein is a receptor molecule that plays a critical role as a negative regulator of the immune response. Therefore, genetic variations in CTLA4 may confer susceptibility to autoimmune diseases such as multiple sclerosis (MS). In order to investigate the association of two CTLA4 polymorphisms (+49 A/G and -318 C/T) with multiple sclerosis, sporadic MS patients and healthy controls from Italy were genotyped through direct DNA sequencing.

Mandibular intrabony lesion as first sign of sarcoidosis: case report.

A 33-year-old woman with intra-bony sarcoidosis of the mandible is reported. This presentation of sarcoidosis was the first sign of the disease in this patient, and was treated surgically because of an inaccurate biopsy report. Medical therapy was instituted once the diagnosis was made, and the disease was well controlled (including the mandibular localization) at 2 years follow-up.

Surgical treatment of wounds of the lower leg and foot with loss of substance.

In the surgical treatment of wounds of the distal regions of the leg with loss of substance, particular anatomical conditions and the frequent coexistence of previous diseases or of diseases connected to the trauma make it hard to choose the most appropriate surgical strategy and require a multidisciplinary approach. Timing and treatment modalities must be decided by different operators in order to ensure a lower risk of post-surgical complications and disabling outcomes. The need for plastic and reconstructive treatment is growing as a result both of the improvement in reconstructive techniques and of the increased incidence of major injuries.

A polymorphism of the interleukin-1 beta gene at position +3953 influences progression and neuro-pathological hallmarks of Alzheimer's disease.

Interleukin-1 (IL-1) gene polymorphisms are associated with an increased risk of Alzheimer's disease (AD) and it has been suggested that altered immune responses of the brain may play a role in the pathogenesis of the disease. Here we investigated whether IL-1beta polymorphisms affected neuro-pathological features and clinical status of AD patients with autopsy confirmed diagnosis of the disease. AD patients (n=133) were genotyped for the polymorphic regions in the apolipoprotein E epsilon (APOE epsilon) and interleukin-1beta (IL-1beta) genes.

Segmental phenolization for the treatment of ingrowing toenails: a review of 6 years experience.

Background: Ingrowing toenails are a common problem causing significant morbidity. Many of the procedures used for treating this painful condition cause considerable discomfort and have high failure rates. In recent years, phenol cauterization of the nail bed has been used increasingly.

Patterns and universals of mate poaching across 53 nations: the effects of sex, culture, and personality on romantically attracting another person's partner.

As part of the International Sexuality Description Project, 16,954 participants from 53 nations were administered an anonymous survey about experiences with romantic attraction. Mate poaching--romantically attracting someone who is already in a relationship--was most common in Southern Europe, South America, Western Europe, and Eastern Europe and was relatively infrequent in Africa, South/Southeast Asia, and East Asia. Evolutionary and social-role hypotheses received empirical support.

Virtual simulation: fifteen years later.

In the last two decades there was a radical change in radiotherapy setup. The growing availability of CT equipment and console for computer-aided treatment planning setup enabled the use of advanced technologies as conformal 3D radiation therapy in most centers. In particular in 1987 virtual simulation was proposed for setup.

Association between the tumor necrosis factor-alpha -308 G/A gene polymorphism and migraine.

In a group of 299 migraine patients and 306 control subjects, the association of the -308 G/A polymorphism in the tumor necrosis factor-alpha gene (TNFalpha) with the occurrence and clinical characteristics of migraine was tested. Homozygosity for the G allele was associated with an increased risk of migraine (odds ratio [OR] = 2.85, p < 0.

Allele frequencies of +874T --> A single nucleotide polymorphism at the first intron of IFN-gamma gene in Alzheimer's disease patients.

Background And Aims: Inflammation seems to play a role in progressive neurological degenerative diseases such as Alzheimer's disease (AD). Local inflammatory processes can in fact give rise to direct neurotoxicity, interfere with beta-amyloid expression and metabolism, and maintain chronic, intracerebral, acute-phase protein secretion, in turn favoring the formation of beta-amyloid fibrils. Accordingly, recent studies show an increased risk for AD associated with certain polymorphisms in the genes encoding some proinflammatory cytokines and acute-phase proteins.

Glucocorticoid-related genetic susceptibility for Alzheimer's disease.

Because glucocorticoid excess increases neuronal vulnerability, genetic variations in the glucocorticoid system may be related to the risk for Alzheimer's disease (AD). We analyzed single-nucleotide polymorphisms in 10 glucocorticoid-related genes in a population of 814 AD patients and unrelated control subjects. Set-association analysis revealed that a rare haplotype in the 5' regulatory region of the gene encoding 11beta-hydroxysteroid dehydrogenase type 1 (HSD11B1) was associated with a 6-fold increased risk for sporadic AD.

An MRI study of Chlamydia pneumoniae infection in Italian multiple sclerosis patients.

We amplified sequences of the Chlamydia pneumoniae (CP) major-outer membrane protein in the cerebrospinal fluid (CSF) from 23 of 107 (21.5%) relapsing-remitting or secondary progressive multiple sclerosis (MS) patients and two of 77 (2.6%) patients with other neurological diseases (OND) (P = 0.

A whole genome screen for linkage disequilibrium in multiple sclerosis performed in a continental Italian population.

We have systematically screened the genome for evidence of linkage disequilibrium (LD) with multiple sclerosis (MS) by typing 6000 microsatellite markers in case-control and family based (AFBAC) cohorts from the Italian population. DNA pooling was used to reduce the genotyping effort involved. Four DNA pools were considered: cases (224 Italian MS patients), controls (231 healthy Italians), index (185 index cases from trio families) and parents (the 370 parents of the patient included in the Index pool), respectively.

Experimental dosimetry of a 32P catheter-based endovascular brachytherapy source.

The experimental dosimetry in a water phantom of a 32P linear source, 20 mm in length, used for the brachytherapy of coronary vessels is reported. The source content activity, A, was determined by means of a calibrated well ion-chamber and the value was compared with the contained activity reported in the manufacturer's certification. In this field of brachytherapy dosimetry, radiochromic film supplies a high enough spatial resolution.

Interleukin-1B polymorphism is associated with age at onset of Alzheimer's disease.

Interleukin-1alpha (IL-1alpha) and IL-1beta are two pro-inflammatory cytokines involved in the pathogenesis of Alzheimer's disease (AD). The genes coding for IL-1alpha (IL-1A) and for IL-1beta (IL-1B) are clustered in chromosome 2q14-2q14.2.

Interleukin-6 gene alleles affect the risk of Alzheimer's disease and levels of the cytokine in blood and brain.

Two different polymorphic regions of the interleukin-6 (IL-6) gene were investigated in patients with Alzheimer's disease (AD) and non-demented controls. The -174 C allele in the promoter region of IL-6 gene was over-represented in AD patients compared to controls and significantly increased the risk of AD. Moreover, the -174 CC genotype was associated with a high risk of the disease in women.

Universal sex differences in the desire for sexual variety: tests from 52 nations, 6 continents, and 13 islands.

Evolutionary psychologists have hypothesized that men and women possess both long-term and short-term mating strategies, with men's short-term strategy differentially rooted in the desire for sexual variety. In this article, findings from a cross-cultural survey of 16,288 people across 10 major world regions (including North America, South America, Western Europe, Eastern Europe, Southern Europe, Middle East, Africa, Oceania, South/Southeast Asia, and East Asia) demonstrate that sex differences in the desire for sexual variety are culturally universal throughout these world regions. Sex differences were evident regardless of whether mean, median, distributional, or categorical indexes of sexual differentiation were evaluated.

Genetic association of acyl-coenzyme A: cholesterol acyltransferase with cerebrospinal fluid cholesterol levels, brain amyloid load, and risk for Alzheimer's disease.

A common polymorphism of the gene encoding acyl-coenzyme A: cholesterol acyltransferase 1 (SOAT1), which is involved in the regulation of beta-amyloid peptide generation, is associated with low brain amyloid load (P=0.03) and with low cerebrospinal fluid levels of cholesterol (P=0.005).

Absence of linkage between the interleukin-6 gene (-174 G/C) polymorphism and migraine.

To assess the role of interleukin-6 (IL-6) in migraine, we analyzed the -174 G/C IL-6 gene polymorphism in 268 patients with migraine and 305 controls. No significant difference in the distribution of IL-6 genotypes (chi(2)=0.601, P=0.

The role of IL-1 gene cluster in longevity: a study in Italian population.

In this study, we analysed the polymorphic variants of IL-1alpha (C-T transition at position -889), IL-1beta (C-T transition at position -511) and IL-1 receptor antagonist (Ra) (86-bp repeated sequence in intron 2) in 1131 subjects (453 females and 678 males) from Northern and Central Italy, including 134 centenarians, to evaluate whether IL-1 cluster alleles might be differently represented in people selected for longevity. In addition, IL-1Ra and IL-1beta plasma levels were quantified by ELISA in 130 randomly selected subjects. No significant differences in the genotype and allele frequency distributions were observed between young, elderly and centenarian subjects.

Association between the HFE mutations and unsuccessful ageing: a study in Alzheimer's disease patients from Northern Italy.

Mutations in the class I-like Major Histocompatibility Complex gene HFE are associated with hereditary hemochromatosis (HH), a disorder caused by excessive iron uptake. Three common mutations have been found: C282Y, H63D, and S65C. Moreover, several studies have suggested that HFE mutations may be involved in several age-related chronic diseases such as Alzheimer's disease (AD) and coronary heart disease, but apparently paradoxically also with longevity.

Interleukin-10 promoter polymorphism in sporadic Alzheimer's disease.

Proinflammatory cytokines and acute-phase proteins play an important role in Alzheimer's disease (AD) neurodegeneration, and common polymorphisms of genes controlling their high production have been shown to be associated with AD. Thus, AD patients display a proinflammatory genotype and the control of inflammation might play a protective role in AD development. By sequence-specific probes, we have evaluated the role of anti-inflammatory cytokine interleukin(IL)-10 in AD, by analysing in 132 AD patients and 213 healthy controls the prevalence of three different haplotypes, involving three single-nucleotide polymorphisms (SNPs) at -1082 (G-->A), -819 (C-->T) and -592 (C-->A) nucleotides of IL-10 promoter, associated with different IL-10 production.
