Color Doppler Ultrasound Supports Early Diagnosis of Mixed High and Low Risk of Recurrence Subtypes in the Same Basal Cell Carcinoma Lesion.

Basal cell carcinoma (BCC) is the most common type of skin cancer and can cause important cosmetic and functional defects. BCC has several high and low risk of recurrence histologic subtypes and the possibility to discriminate them noninvasively in the same lesion may support the management and improve the cosmetic prognosis. Total excision is the most effective treatment, but in certain anatomic locations such as the face may result in significant disfigurement. The histologic subtype of BCC is oneof themost important factors that can influence recurrence and may affect the therapeutic approach. According to literature, the reported frequency of mixed histologic subtypes of BCC varies between18%and50%. Although incisionalbiopsy can confirm the diagnosis before complete excision, in some cases the samplemaynot be representative and fail in the diagnosis of histologic subtype(s), which could affect the prognosis and treatment. In this context, color Doppler ultrasound can be useful for the diagnosis and presurgical planning because it can provide important information on tumor extent and deeper layers involvement, which may be of paramount importance e.g., in the face to improve the cosmetic prognosis. Color Doppler ultrasound can also support the prediction of high (e.g., micronodular and morpheiform) and low risk of recurrence (e.g., nodular and superficial) histologic subtypes of BCC by counting the amount of hyperechoic spots within the tumor. These hyperechoic spots correlate on histologywith areas that contain compact tumoral nests of atypical basaloid cells, which allow a posterior acoustic transmission artifact.
Global Consensus Guidelines for the Injection of Diluted and Hyperdiluted Calcium Hydroxylapatite for Skin Tightening

BACKGROUND Calcium hydroxylapatite (CaHA) is approved to correct moderate-to-severe wrinkles and folds and soft-tissue volume loss in the face and hands. More recently, subdermal injection using diluted CaHA has been used to improve skin laxity. OBJECTIVE To review evidence for the safe and effective use of diluted CaHA in the face and body and provide best practice recommendations. METHODS A global panel of expert aesthetic physicians convened to develop consensus-based guidelines for treating laxity and superficial wrinkles using diluted (ratio of 1:1) and hyperdiluted (≥1:2) CaHA. RESULTS Diluted and hyperdiluted CaHA stimulates targeted neocollagenesis in the injection area to improve laxity and skin quality in the mid- and lower face, neck, décolletage, upper arms, abdomen, upper legs, and buttocks. Treatment can be used as an adjunct to volume augmentation or combined with additional modalities for optimal results. Adverse events are related to the injection and include bruising, swelling, mild pain, and induration. In thinner and darker skin, too-superficial injections of less diluted CaHA can lead to more adverse events. CONCLUSION This report provides preliminary guidelines for the novel off-label use of CaHA for biostimulation in the face and body. Further trials will provide additional clarity regarding treatment paradigms for optimal outcomes.
Opportunities to intervene? “Warning signs” for suicide in the days before dying

ABSTRACT To validate warning signs for suicide, researchers interviewed 20 respondents, representing 17 suicides in Orleans Parish, Louisiana, about characteristics of the decedent in the year, month, and days preceding the death. Decedents did exhibit behaviors consistent with existing warning signs, but these were rarely new behaviors present 7 days prior to the suicide but not previously. Research is needed to continue to test warning signs for suicide, and education campaigns that teach warning signs may not be relevant for preventing suicide among those in mental health treatment or involved in the criminal justice system.
Quantitative EEG Power and Asymmetry Increase 36 h Before a Migraine Attack

The aim was to estimate ictal, pre- and postictal brain function changes in migraine in a blinded paired quantitative EEG (QEEG) study. EEG recordings (n = 119) from 40 migraineurs were retrospectively classified as ictal, interictal, preictal or postictal. δ, θ, α and β power, and hemispheric asymmetry in frontocentral, temporal and occipitoparietal regions were calculated from artefact-free EEG. Power and power asymmetry were calculated for two time-windows, 36 and 72 h before/after the attack, and compared with the interictal values. Frontocentral δ power increased (P = 0.03), whereas frontocentral θ and α power tended to increase (P < 0.09) within 36 h before the next attack compared with the interictal period. Occipitoparietal (α and θ) and temporal (α) power were more asymmetric before the attack compared with the interictal baseline (P < 0.04). Ictal posterior a power increased slightly (P = 0.01). Postictal power and power asymmetry were not significantly different from interictal baseline. EEG activity seems to change shortly before the attack. This suggests that migraineurs are most susceptible to attack when anterior QEEG δ power and posterior α and θ asymmetry values are high. Changed activity patterns in cholinergic brainstem or basal forebrain nuclei and thalamo-cortical connections before the migraine attack are hypothesized.
Ambient Particulate Air Pollution and MicroRNAs in Elderly Men

Background: Ambient particulate matter (PM) has been associated with mortality and morbidity for cardiovascular disease. MicroRNAs control gene expression at a posttranscriptional level. Altered microRNA expression has been reported in processes related to cardiovascular disease and PM exposure, such as systemic inflammation, endothelial dysfunction, and atherosclerosis. Polymorphisms in microRNA-related genes could influence response to PM. Methods: We investigated the association of exposure to ambient particles in several time windows (4-hour to 28-day moving averages) and blood leukocyte expression changes in 14 candidate microRNAs in 153 elderly males from the Normative Aging Study (examined 2005–2009). Potential effect modification by six single nucleotide polymorphisms (SNPs) in three microRNA-related genes was investigated. Fine PM (PM2.5), black carbon, organic carbon, and sulfates were measured at a stationary ambient monitoring site. Linear regression models, adjusted for potential confounders, were used to assess effects of particles and SNP-by-pollutant interaction. An in silico pathway analysis was performed on target genes of microRNAs associated with the pollutants. Results: We found a negative association for pollutants in all moving averages and miR-1, -126, -135a, -146a, -155, -21, -222, and -9. The strongest associations were observed with the 7-day moving averages for PM2.5 and black carbon and with the 48-hour moving averages for organic carbon. The association with sulfates was stable across the moving averages. The in silico pathway analysis identified 18 pathways related to immune response shared by at least two microRNAs; in particular, the “high-mobility group protein B1/advanced glycosylation end product–specific receptor signaling pathway” was shared by miR-126, -146a, -155, -21, and -222. No important associations were observed for miR-125a-5p, -125b, -128, -147, -218, and -96. We found significant SNP-by-pollutant interactions for rs7813, rs910925, and rs1062923 in GEMIN4 and black carbon and PM2.5 for miR-1, -126, -146a, -222, and -9, and for rs1640299 in DGCR8 and SO42− for miR-1 and -135a. Conclusions: Exposure to ambient particles could cause a downregulation of microRNAs involved in processes related to PM exposure. Polymorphisms in GEMIN4 and DGCR8 could modify these associations.
Type I interferon in HIV treatment: from antiviral drug to therapeutic target

Type I interferons (IFNs) are soluble molecules that exert potent antiviral activity and are currently used for the treatment of a panel of viral infections. In the case of HIV, the use of type I IFN has had limited success, and has almost been abandoned. During the last decade, a series of studies has highlighted how HIV infection may cause overactivation of type I IFN production, which contributes to the exhaustion of the immune system and to disease progression. This review describes the transition from the proposed use of type I IFN as antiviral drugs in HIV infection, to the idea that blocking their activity or production may provide an immunologic benefit of much greater importance than their antiviral activity.
Febrile Urinary Tract Infection in Infants Less than Two Months of Age : Characteristics and Factors Related to the Recurrence

Purpose: The aim of this study is to characterize and to investigate the factors related to the recurrence of febrile urinary tract in- fection (UTI) in infants less than 2 months of age. Methods: We performed a retrospective study in 60 infants, who were treated for the first febrile UTI. Among them, 27 infants were followed for 12 months, and were reviewed concerning the factors related to the recurrence. The factors compared for the recurrence included sex, age at diagnosis, laboratory and radiologic findings like degree of the reflux and renal cortical defect. Results: Among the 60 infants studied, 52 were male (86.7%). Age at diagnosis was 39±13 days. The most common pathogen was E.coli (71.7%). The infants underwent an ultrasonography (n=59), DMSA scan (n=55), and voiding cystourethrography (VCUG). Further hydronephrosis, renal cortical defect, vesicoureteral reflux (VUR) were found in 28 (47.4%), 12 (21.8%) and 11 (20.4%) in- fants, respectively. The hydronephrosis was found frequently in the recurrent UTI group (P=0.012). The VUR was found frequently, but not significantly, in therecurrent UTI group (44.4%) than that of the non-recurrent UTI group (16.7%). Conclusion: During the 12 months after the first febrile UTI, hydronephrosis increased the risk of recurrent UTI. The ultrasonogra- phy is needed during the follow up of UTI in infants less than two months of age.
Impact of Noise and Air Pollution on Pregnancy Outcomes

Background: Motorized traffic is an important source of both air pollution and community noise. While there is growing evidence for an adverse effect of ambient air pollution on reproductive health, little is known about the association between traffic noise and pregnancy outcomes. Methods: We evaluated the impact of residential noise exposure on small size for gestational age, preterm birth, term birth weight, and low birth weight at term in a population-based cohort study, for which we previously reported associations between air pollution and pregnancy outcomes. We also evaluated potential confounding of air pollution effects by noise and vice versa. Linked administrative health data sets were used to identify 68,238 singleton births (1999–2002) in Vancouver, British Columbia, Canada, with complete covariate data (sex, ethnicity, parity, birth month and year, income, and education) and maternal residential history. We estimated exposure to noise with a deterministic model (CadnaA) and exposure to air pollution using temporally adjusted land-use regression models and inverse distance weighting of stationary monitors for the entire pregnancy. Results: Noise exposure was negatively associated with term birth weight (mean difference = −19 [95% confidence interval = −23 to −15] g per 6 dB(A)). In joint air pollution-noise models, associations between noise and term birth weight remained largely unchanged, whereas associations decreased for all air pollutants. Conclusion: Traffic may affect birth weight through exposure to both air pollution and noise.
Interrelation of Chronic Tension-Type Headache With and Without Medication Overuse and Migraine in the General Population: The Akershus Study of Chronic Headache

We studied the interrelation of chronic tension-type headache with and without medication overuse (CTTH) and migraine in a random sample of 30 000 persons aged 30–44 years. They received a mailed questionnaire. Those with a possible chronic headache were interviewed by neurological residents. The International Classification of Headache Disorders was used. A total of 386 persons had CTTH. Compared with the general population, men had a 2.8-fold and women a 2.4-fold significantly increased risk of migraine without aura (MO). The risk of migraine with aura (MA) was not increased. The mean age at onset of CTTH was significantly higher in those with than in those without co-occurrence of MO. Bilateral MO attacks were significantly more frequent in those with age at onset of CTTH prior to age at onset of MO compared with those with age at onset in reverse order. CTTH and MO are interrelated, possibly in a complex matter. In contrast, CTTH and MA are not interrelated.
Early- or mid-trimester amniocentesis biomarkers for predicting preterm delivery: a meta-analysis

Abstract Objective: To determine the value of early- or mid-trimester amniotic fluid levels of interleukin-6 (IL-6), matrix metalloproteinase-8 (MMP-8), and glucose for predicting preterm delivery. Methods: Randomized controlled trials and two-arm prospective, retrospective, cohorts, and case-controlled studies in which patients received early- or mid-trimester amniocentesis for karyotyping, and biomarker testing of the amniotic fluid was performed and delivery data were available were included in the analysis. Results: Outcome measures were the associations of amniotic fluid IL-6, MMP-8, and glucose levels with preterm delivery. Differences in means with 95% confidence intervals (CIs) were calculated. Of 288 articles identified, 14 were included in the meta-analysis with a total of 675 patients who had preterm birth and 2518 patients who had term births. The preterm-delivery group had significantly higher amniotic fluid IL-6 and MMP-8 levels, and a significantly lower glucose level than the term delivery group (IL-6: difference in means = 0.32, 95% CI: 0.22–0.43, p < 0.001; MMP-8: difference in means = 4.47, 95% CI: 0.83–8.11), p = 0.016; glucose: difference in means = −5.22, 95% CI: −8.19 to −2.26, p = 0.001) Conclusion: Early- or mid-trimester amniotic fluid IL-6, MMP-8, and glucose levels are useful for predicting the risk of preterm delivery. KEY MESSAGES Median amniotic fluid ferritin and IL-6 levels, and mean amniotic fluid ALP levels were higher in the preterm group. The preterm-delivery group had significantly higher amniotic fluid IL-6 and MMP-8 levels, and a significantly lower glucose level than the term-delivery group.
Effects of direct renin inhibition versus angiotensin II receptor blockade on angiotensin profiles in non-diabetic chronic kidney disease

Abstract Background: Direct renin inhibition (DRI) is clinically inferior to other blockers of the renin–angiotensin system (RAS). Thus far, the underlying molecular causes of this finding remain unknown. Methods: Twenty four patients with non-diabetic chronic kidney disease (CKD) stages III–IV and albuminuria were randomized to DRI or angiotensin receptor blocker (ARB). Employing a novel mass-spectrometry method, the concentrations of renin, aldosterone and plasma angiotensin peptides [Ang I, Ang II, Ang-(1-7), Ang-(1-5), Ang-(2-8), Ang-(3-8)] were quantified before and after an 8-week treatment. Results: While blood pressure, renal function and albuminuria decreased comparably in both groups, profound RAS component differences were observed: DRI led to a massive renin increase, while suppressing both vasoconstrictive (Ang I and Ang II) and vasodilatory RAS metabolites (Ang-(1-7) and Ang-(1-5)). In contrast, ARB led to a four-fold increase of Ang I and Ang II, while Ang-(1-7) and Ang-(1-5) increased moderately but significantly. With ARB treatment, a decreased aldosterone-to-Ang II ratio suggested efficacy in blocking AT1 receptor. Conclusions: DRI therapy abolishes all RAS effector peptides. ARB increases both vasoconstrictive and vasodilative angiotensins, while this is accompanied by efficient blockade of vasoconstrictive effects. These differential molecular regulations should be considered when selecting optimal antihypertensive and disease-modifying therapy in CKD patients. Key messages Direct renin inhibition leads to a complete and lasting abolition of both classical and alternative RAS components. Angiotensin receptor blockade leads to effective receptor blockade and up-regulation of alternative RAS components. Differential molecular regulations of the RAS should be considered when selecting optimal antihypertensive and disease-modifying therapy in CKD patients.
Sepsis in Internal Medicine wards: current knowledge, uncertainties and new approaches for management optimization

Abstract Sepsis represents a global health problem in terms of morbidity, mortality, social and economic costs. Although usually managed in Intensive Care Units, sepsis showed an increased prevalence among Internal Medicine wards in the last decade. This is substantially due to the ageing of population and to multi-morbidity. These characteristics represent both a risk factor for sepsis and a relative contra-indication for the admission to Intensive Care Units. Although there is a lack of literature on the management of sepsis in Internal Medicine, the outcome of these patients seems to be gradually improving. This is due to Internists’ increased adherence to guidelines and “bundles”. The routine use of SOFA score helps physicians in the definition of septic patients, even if the optimal score has still to come. Point-of-care ultrasonography, lactates, procalcitonin and beta-d-glucan are of help for treatment optimization. The purpose of this narrative review is to focus on the management of sepsis in Internal Medicine departments, particularly on crucial concepts regarding diagnosis, risk assessment and treatment. Key Messages Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. The prevalence of sepsis is constantly increasing, affecting more hospital patients than any other disease. At least half of patients affected by sepsis are admitted to Internal Medicine wards. Adherence to guidelines, routine use of clinical and lab scores and point-of-care ultrasonography are of help for early recognition of septic patients and treatment optimization.
Cardiovascular Disease Mortality Among Breast Cancer Survivors

Background: Cardiovascular disease (CVD) is of increasing concern among breast cancer survivors. However, the burden of this comorbidity in this group relative to the general population, and its temporal pattern, remains unknown. Methods: We compared deaths due to CVD in a population-based sample of 1,413 women with incident breast cancer diagnosed in 1996–1997, and 1,411 age-matched women without breast cancer. Date and cause of death through December 31, 2009 were assessed through the national death index and covariate data was gathered through structured interviews and medical record abstraction. Hazard ratios (HR) and 95% confidence intervals were calculated using Cox regression for overall mortality (HR) and CVD-specific death (cause-specific HR). Subdistribution HRs for CVD death were estimated from the Fine-Gray model. Results: Risk of death was greater among breast cancer survivors compared with women without breast cancer (HR: 1.8 [1.5, 2.1]). An increase in CVD-related death among breast cancer survivors was evident only 7 years after diagnosis (years 0–7, cause-specific HR: 0.80 [0.53, 1.2], subdistribution HR: 0.59 [0.40, 0.87]); years 7+, cause-specific HR: 1.8 [1.3, 2.5], subdistribution HR: 1.9 [1.4, 2.7]; P interaction: 0.001). An increase in CVD-related mortality was observed among breast cancer survivors receiving chemotherapy. Conclusions: Breast cancer survivors are at greater risk for CVD-related mortality compared with women without breast cancer and this increase in risk is manifested approximately 7 years after diagnosis. Efforts should be made to identify risk factors and interventions that can be employed during this brief window to reduce the excess burden of CVD in this vulnerable population.
A problemática da adesão na prevenção da anemia ferropriva e suplementação com sais de ferro no município de Viçosa (MG)

The scope of this article is to analyze the understanding of mothers and persons responsible for infants taking ferrous sulfate supplement about anemia and its consequences, assessed by the level of adherence to supplementation. A prospective, qualitative and quantitative population study was conducted with non-anemic children not taking supplements to receive prophylactic supplementation with ferrous sulfate for six months. After six months, there was adherence to supplementation. Among the 133 children initially eligible for the study, 97 returned for the second evaluation. Of these, 4 had anemia during the follow-up and began treatment and 3 others were brought in by individuals who were unable to provide information on use of the supplement. High adherence was showed by 56.7% of children and low adherence by 43.3%, while 23.3% had interrupted supplementation due to the lack of guidance and support of the health service. Mothers and persons responsible of the two groups (high and low adherence) manifested little knowledge about anemia, its prevention and health consequences for the child. More information regarding iron deficiency anemia, routine follow-up by professionals and evaluation of the perception of individuals involved with iron supplementation is necessary.
Depression: Clinical, Experimental, and Theoretical Aspects

His propensity to deal with the symptomatic aspects of depression, without regarding nosological classification of psychiatric diseases, creates some difficulties. Where he attempts to differentiate neurotic from true, endogenous depressions, Beck utilizes only cross-sectional symptomatology, and he finally concludes that there are no specific signs and symptoms, aside from delusions, to distinguish psychotic from neurotic depressions. Thus he supports the thesis that the two conditions differ only in quantitative aspects. However, in the reviewer's experience, longitudinal studies indicate a high incidence of hysterical reactions, alcoholism, and other pathological features in the personality of individuals with neurotic depressions, as well as the absence of manic episodes. After offering data which purport to indicate a higher incidence of orphanage in depressed individuals, Beck develops the thesis that parental deprivation in childhood may be a factor in later development of severe depression. Elsewhere, the reviewer has recorded detailed criticism of these data and

Sickle cell trait: heterozygous for the hemoglobin S

Hemoglobin S (HbS) is one of the most common hereditary hematological alterations. In Brazil, the frequency of the sickle cell trait (HbAS) varies from 2% to 8%. Thus, there is an estimate of more than two million carriers of the HbAS sickle cell trait in Brazil. Different to homozygous carriers for Hb S (Hb SS), individuals with the sickle cell trait do not present with vaso-occlusive symptoms under physiologic conditions. Some clinical signals associated to the sickle cell trait only occur under conditions that favor the sickling process, including hypoxia, acidosis and dehydration. Life expectancy is similar to the general population. Hence, the condition of asymptomatic carrier should not affect the style and quality of life.
