Abstract
Aging is a major risk factor in amyotrophic lateral sclerosis (ALS) and other adult-onset neurodegenerative disorders. Whereas young neurons are capable of buffering disease-causing stresses, mature neurons lose this ability and degenerate over time. We hypothesized that the resilience of young motor neurons could be restored by re-expression of the embryonic motor neuron selector transcription factors ISL1 and LHX3. We found that viral re-expression of ISL1 and LHX3 reactivates aspects of the youthful gene expression program in mature motor neurons and alleviates key disease-relevant phenotypes in the SOD1G93A mouse model of ALS. Our results suggest that redeployment of lineage-specific neuronal selector transcription factors can be an effective strategy to attenuate age-dependent phenotypes in neurodegenerative disease.

Analysis of peri-implant bone defects by using cone beam computed tomography (CBCT): an integrative review. Oral Radiol 2023:10.1007/s11282-023-00683-w. [PMID: 37058184 DOI: 10.1007/s11282-023-00683-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Accepted: 03/30/2023] [Indexed: 04/15/2023]
Abstract
The objective of this work was to perform an integrative review of the inspection of peri-implant bone defects using cone beam computed tomography (CBCT). An electronic search was performed in the PubMed database using the following scientific terms: CBCT or Cone Beam computed tomography; dental implant; peri-implant; bone loss; defects. The survey identified 267 studies, of which 18 were considered relevant to this study. These studies provided important data taking into account the accuracy of cone beam computed tomography in the detection and measurement of peri-implant bone defects such as fenestrations, dehiscence and intraosseous circumferential defects. The effectiveness of CBCT in aiding in geometric bone calculations and in the diagnosis of peri-implant defects was influenced by factors such as artefacts, defect size, bone wall thickness, implant material, adjustment of acquisition parameters and observer experience. A not insignificant number of studies compared intraoral radiography to CBCT in the detection of peri-implant bone loss. CBCT was clearly superior to intraoral radiography in the detection of all peri-implant bone defects, except for defects located in the interproximal zone. In general, studies have shown that peri-implant bone measurements adjacent to the implant surface can be correctly determined, as well as the diagnosis of peri-implant bone defects with an average discrepancy of less than 1 mm from the actual measurement of the defect.

Abstract
SummaryThe World Health Organization (WHO) Somatoform Disorders Schedule (SDS) is a highly standardized instrument for the assessment of somatoform disorders according to the tenth revision of the International Classification of Diseases (ICD-10) and the fourth edition of the Diagnostic and Statistical Manual (DSM-IV). The SDS was produced in the framework of the WHO International Study of Somatoform Disorders and tested for its reliability in Brazil, India, Italy, the USA and Zimbabwe. A sample of 180 patients from general psychiatry, primary care and general medical settings were interviewed with the SDS within a three-day interval by nonclinician and clinician interviewers. The agreement between the two interviews was tested using the intraclass correlation coefficients (ICC) and kappa statistic. The test-retest reliability of the SDS was found to be very good (the ICC for all the centres was 0.76; overall kappa value for SDS questions was 0.58; one-third of SDS questions had a kappa value of 0.60 or higher). The field test results of the SDS indicated that the instrument may be administered in larger studies by non-clinician interviewers without compromising the ability to document the prevalence of somatoform disorders in different cultures.

Abstract
Non-fibrillar soluble oligomeric forms of amyloid-β peptide (oAβ) and tau proteins are likely to play a major role in Alzheimer's disease (AD). The prevailing hypothesis on the disease etiopathogenesis is that oAβ initiates tau pathology that slowly spreads throughout the medial temporal cortex and neocortices independently of Aβ, eventually leading to memory loss. Here we show that a brief exposure to extracellular recombinant human tau oligomers (oTau), but not monomers, produces an impairment of long-term potentiation (LTP) and memory, independent of the presence of high oAβ levels. The impairment is immediate as it raises as soon as 20 min after exposure to the oligomers. These effects are reproduced either by oTau extracted from AD human specimens, or naturally produced in mice overexpressing human tau. Finally, we found that oTau could also act in combination with oAβ to produce these effects, as sub-toxic doses of the two peptides combined lead to LTP and memory impairment. These findings provide a novel view of the effects of tau and Aβ on memory loss, offering new therapeutic opportunities in the therapy of AD and other neurodegenerative diseases associated with Aβ and tau pathology.

Abstract
OBJECTIVE To study the concordance of the radiographic classification of Eaton-Littler for the diagnosis of basal thumb joint osteoarthritis (BTJO). The null hypothesis was that the concordance was due to chance and the alternative was that the concordance was not due to chance. MATERIAL AND METHOD We have observed the x-rays of 46 patients with symptoms and clinical signs of BTJO. They were independently classified by five physicians: three experts in upper extremity, one in radiology and a fourth year resident of Orthopedics. We studied the concordance in the observations through the global Kappa. DISCUSSION The diagnosis of BTJO is based primarily on clinical exploration, radiology is a complementary method of confirmation. The classification of Eaton-Littler proposes 4 stages of the disease, with a therapeutic involvement. CONCLUSIONS The concordance of the radiographic classification of Eaton-Littler is moderate.

Recurrent Focal myositis: a rare inflammatory myopathy. ACTA REUMATOLOGICA PORTUGUESA 2014; 39:172-175. [PMID: 24859416] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/03/2023]
Abstract
Focal myositis is an acute and localized muscle inflammation of unknown aetiology. The clinical diagnosis is often difficult to obtain, since it can be confused with infections, vascular thrombosis or muscle tumours such as sarcomas. This leads to a significant delay in the diagnosis, resulting in the administration of inappropriate and potentially harmful treatments. We report here a case of recurrent focal myositis in a woman where the diagnosis was only obtained after 6 years, despite multiple hospital admissions. This case reinforces the importance of clinical knowledge and experience to tackle challenging medical scenarios.

Abstract
OBJECTIVE To develop Portuguese evidence-based recommendations for the Diagnosis and Management of Gout. METHODS As part of the 3e Initiative (Evidence, Expertise and Exchange), a panel of 78 international rheumatologists developed 10 relevant clinical questions which were investigated with systematic literature reviews. MEDLINE, EMBASE, Cochrane CENTRAL and abstracts from 2010-2011 EULAR and ACR meetings were searched. Based on the evidence found in the published literature, rheumatologists from 14 countries developed national recommendations that were merged and voted into multinational recommendations. We present the Portuguese recommendations for the Diagnosis and Management of Gout which were formulated and voted by Delphi method in April 2012, in Lisbon. The level of agreement and potential impact in clinical practice was also assessed. RESULTS Twelve national recommendations were elaborated from 10 international and 2 national questions. These recommendations addressed the diagnosis of gout; the treatment of acute flares and urate-lowering therapy; monitoring of gout and comorbidity screening; the influence of comorbidities in drug choice; lifestyle; flare prophylaxis; management of tophi and asymptomatic hyperuricaemia; the role of urine alkalinization; and the burden of gout. The level of agreement with the recommendations ranged from 6.8 to 9.0 (mean 7.7) on a 1-10 point visual analogue scale, in which 10 stands for full agreement. CONCLUSION The 12 Portuguese recommendations for the Diagnosis and Management of Gout were formulated according to the best evidence and endorsed by a panel of 42 rheumatologists, enhancing their validity and practical use in daily clinical practice.

Abstract
The posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological entity characterized by the association of clinical neurological signs (headache, confusion, vision changes, vomiting and seizures) and the typical changes in magnetic resonance imaging of the brain. Its pathogenesis is still poorly defined but seems to imply a vascular and endothelial dysfunction. It occurs more frequently in patients with hypertensive encephalopathy, eclampsia, renal failure and has also been associated with the use of immunosuppressive drugs. The authors present a case of PRES in a young woman with systemic lupus erythematosus with active and severe manifestations of the disease.

Abstract
OBJECTIVE The International Diabetes Federation (IDF) has recently published the new criteria for the diagnosis of metabolic syndrome. The aim of this study was to compare the clinical characteristics and cardiovascular risk of the new patients with MS compared to the previous National Cholesterol Education Program ATP III definition, its differential characteristics and cardiovascular risk. PATIENTS AND METHODS Cross sectional study in a hypertension clinic. Coronary risk was calculated (Framingham function NCEP-ATP III) and other cardiovascular markers, urinary albumin excretion (UAE in mg/24 hours) and high sensitivity C-reactive protein (CRP) were assessed. RESULTS A total 2,404 patients were evaluated, 1,901 non-diabetic and 503 diabetic hypertensive subjects. The non-diabetics 726 (38.2%) had MS with the previous NCEP ATP-III definition, the number increasing sharply to 1,091 (57.4%) with the new IDF definition. The proportion did not increase in diabetics (93% vs. 92%). Concordance in the diagnosis was 78% in non-diabetics and 91% in diabetics. The new patients had a similar coronary risk (Framingham) but lower values of other cardiovascular markers: logUAE 1.00 (0.49) mg/24 hours vs. 1.06 (0.55) mg/24 hours (p = 0.003), and CRP 1.9 (2.7) mg/L vs. 2.5 (3.2) mg/L (median, interquartile range; p < 0.001). CONCLUSIONS The new IDF definition of MS increases the number of patients with MS. The new patients have a similar coronary risk (Framingham) but the new parameters used to assess cardiovascular risk (UAE and CRP) were lower. The relationship of the new definition of MS and cardiovascular risk remains to be defined.

Abstract
OBJECTIVE The last modifications of the National Cholesterol Education Program (NCEP) indicate some lower therapeutic targets of low density protein cholesterol (LDL-c) in patients with very high vascular risk. Our study aims to establish the degree of compliance of the therapeutic targets defined by these modifications. PATIENTS AND METHOD Descriptive and cross sectional study of patients from a cardiovascular clinic. Low-density lipoprotein cholesterol (LDL-c) was calculated and targets were established according the new update of NCEP-ATP III. RESULTS 836 patients, 625 (75%) with HR and 211(25%) with VHR were studied 45% of HR and 67% of VHR were receiving treatment with statins (p < 0.001) but only 38% of HR and 15% of VHR achieved target LDL-c levels. The percentage of patients who could achieve LDL-goals using the maximum approved dose of the statins plus other lipid lowering drug was calculated: The 31% of HR and 51% of VHR were unable to achieve the LDL-c targets. CONCLUSIONS Only 15% of very high risk patients achieve target levels of LDL-c according to the new NCEP-ATP III recommendations. Even using maximum dose of statins in combination with other lipid lowering drugs, less than half of the patients will be able to achieve LDL-c goal (< 70 mg/dl).

Abstract
OBJECTIVE C-reactive protein (CRP) is considered a marker of subclinical atherosclerosis. The aim of the study was to assess whether the metabolic syndrome (MS) and parameters involved in its diagnosis might influence serum CRP values. PATIENTS AND METHOD Cross-sectional study in outpatients of a HTA and Vascular Risk clinic. MS was diagnosed according to National Cholesterol Educational Program ATP-III guidelines, and hs-CRP was analyzed by nephelometry. RESULTS A total of 1,969 patients (47% male) were evaluated and distributed into four groups: 1) 1,220 non-diabetics without MS; 2) 384 non-diabetics with MS; 3) 153 diabetics without MS, and 4) 212 diabetics with MS. Patients with MS had higher CRP in both non-diabetic 3.0 (1.7-4.4) mg/l vs. 1.7 (0.9-3.4) mg/l; p=0.001 (MW), and diabetic patients: 2.8 (1.5-4.6) mg/l vs. 2.2 (0.9-4.3) mg/l; p=0.01 (MW). Diabetic patients without MS had CRP values not different to non-diabetic without MS. CRP values increased in relation to the number of parameters included in the MS from 1.7 (2.2) mg/l, in patients without any parameters, to 4.2 (2.8) mg/l in patients who fulfilled five parameters (p=0.001) (KW). In multiple regression analysis abdominal obesity (p=0.001), TG (p=0.001) and glucose (p=0.02) were associated with CRP levels after correcting for other factors. Abdominal obesity (OR: 1.9; 95% CI: 1.5-2.4; p=0.001) and TG (OR: 1.4; 95% CI: 1.1 -1.7; p=0.003), but not glucose were independent factors related to the presence of high levels of CRP (>3 mg/l) in a logistic regression analysis. CONCLUSIONS Diabetic and non-diabetic patients with MS have high CRP levels. Of the five components of MS, the most closely related to CRP is abdominal obesity.

Abstract
The effect of the malnutrition during suckling on the aggressiveness was investigated in adult rats treated or not with citalopram, a selective serotonin reuptake inhibitor (SSRI). The animals were divided into two groups according to the diet used: nourished group - the rats received the control diet with 23% protein during the life; and malnourished group - the rats had its mothers submitted to diet with 7.8% protein during suckling. At 120 days of age, each group was sub-divided according to the treatment: acute - consisting a single i.p. injection of saline solution or 20-mg/Kg citalopram; chronic - consisting the single injections (1 per day during 14 days) of saline or 20 mg/Kg citalopram. The acute or chronic treatment with SSRI reduces aggressive response in nourished rats, but not in malnourished ones. Thus, the malnutrition during the critical period of brain development seems to induce durable alterations in the function of the serotoninergic neurotransmission

Abstract
Most studies suggest that serotonin exerts an inhibitory control on the aggression process. According to experimental evidence, this amine also influences growth and development of the nervous tissue including serotoninergic neurons. Thus, the possibility exists that increased serotonin availability in young animals facilitates a long-lasting effect on aggressive responses. The present study aimed to investigate the aggressive behavior of adult rats (90-120 days) treated from the 1st to the 19th postnatal day with citalopram (CIT), a selective serotonin reuptake inhibitor (20 mg/kg, s.c., every 3 days). Aggressive behavior was induced by placing a pair of rats (matched by weight) in a box (20 x 20 x 20 cm), and submitting them to a 20-min session of electric footshocks (five 1.6-mA - 2-s current pulses, separated by a 4-min intershock interval). When compared to the control group (rats treated for the same period with equivalent volumes of saline solution), the CIT group presented a 41.4% reduction in the duration of aggressive response. The results indicate that the repeated administration of CIT early in life reduces the aggressive behavior in adulthood and suggest that the increased brain serotoninergic activity could play a role in this effect.

Abstract
A clear understanding of the pathophysiology and neurophysiologic effect of neuromodulation is lacking. Apparently there is a balance of efferent and afferent negative and positive feedback loops that are augmented by external electrical stimulation. This effect may be dramatic even in patients who have have not benefited from virtually every other form of treatment.

Abstract
PURPOSE To investigate the mechanism of methylene blue-induced radiosensitization in Escherichia coli cells. MATERIALS AND METHODS Bacteriophage lambda15 was irradiated with X-rays in the presence or absence of methylene blue (MB) and infected into bacteria with different repair capabilities preincubated with or without MB. The survival of the bacteriophage in each bacterial strain was used to quantify MB-induced radiosensitization. DNA repair in bacteria irradiated with X-rays and incubated with or without MB was examined by alkaline and neutral sucrose gradients. An in vitro repair system of pBR322 plasmid DNA irradiated with X-rays was designed to determine the repair enzyme targeted by MB. CONCLUSIONS MB impairs the repair activity of the polymerase 1 enzyme in E. coli cells, sensitizing these bacteria to the lethal effects of ionizing radiation. Since MB accumulates preferentially in some malignant tumours, it will be of interest to investigate its effects on the repair of irradiated human cells.

Abstract
Determining the structure of data without prior knowledge of the number of clusters or any information about their composition is a problem of interest in many fields, such as image analysis, astrophysics, biology, etc. Partitioning a set of n patterns in a p-dimensional feature space must be done such that those in a given cluster are more similar to each other than the rest. As there are approximately Kn/K! possible ways of partitioning the patterns among K clusters, finding the best solution is very hard when n is large. The search space is increased when we have no a priori number of partitions. Although the self-organizing feature map (SOM) can be used to visualize clusters, the automation of knowledge discovery by SOM is a difficult task. This paper proposes region-based image processing methods to post-processing the U-matrix obtained after the unsupervised learning performed by SOM. Mathematical morphology is applied to identify regions of neurons that are similar. The number of regions and their labels are automatically found and they are related to the number of clusters in a multivariate data set. New data can be classified by labeling it according to the best match neuron. Simulations using data sets drawn from finite mixtures of p-variate normal densities are presented as well as related advantages and drawbacks of the method.

Abstract
Between January 1968 and December 1992, 136 kidney transplants were performed in the University Hospital of Ribeirão Preto, with women of childbearing age (14 to 40 years) as receptors. From this population, 19 patients became pregnant at least once after transplantation, and 2 were transplanted inadvertently during the first trimester of their pregnancies. There was a total of 25 pregnancies and 27 offspring. The mean age at the time of conception was 28.6 years (23 to 41 years), with a mean interval of 3.5 years from transplant to conception (< 1 to 16 years). All patients continued their immunosuppressive regimens during the entire pregnancy, but only 5 of 25 were taking cyclosporine. There were two miscarriages (8%) and two therapeutic abortions (8%); of those that passed the 20th week of pregnancy, the mean gestation time at delivery was 35 weeks (range, 28 to 38 weeks) with an incidence of prematurity (gestation < 37 weeks) of 67%, and their offspring weighed from 670 to 3,100 g (mean, 2,236 g), presenting a very high incidence of low birthweight (64%). There was one stillborn and one neonatal death. The most common complications that occurred during pregnancy were infections (especially urinary tract and vaginal mycotic infections) followed by hypertension. The obstetric complications were distributed as follows: premature rupture of membranes in 27%, fetal distress in 24%, preterm labor in 24%, and oligohydramnios in 10%. Lower segment cesarean section was necessary in 16 of 21 cases (76%), and all were for obstetric reasons. One patient died during the puerperium because of sepsis.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The effect of treatment with naloxone early in life on pain responsiveness was studied in Wistar rats. Litters of six rats were divided equally into groups of 3 pups receiving daily naloxone (50 mg/kg, sc) and 3 pups receiving saline from the 3rd to 18th day of life. On days 30, 50, 70 and 90, one group of animals previously injected during suckling with naloxone (N = 21) and another with saline (N = 21) were submitted to the hot-plate test to measure the latency to paw licking. Other groups of rats also treated during suckling with naloxone (N = 13) and saline (N = 14) were assessed for the antinociceptive effect of morphine (10 mg/kg,sc). The naloxone group displayed a lower latency than the saline group in all test sessions and a diminished analgesic response to morphine. The results indicate that the use of naloxone (an antagonist opioid) during suckling, the brain growth spurt period, facilitates a long-lasting increased pain responsiveness and alters antialgesic mechanisms. In this respect, the opioid and non-opioid effects of naloxone on the ontogeny of neural systems should be taken into account.

Abstract
Recording clinic data is essential to the process of evaluation of medical proceedings but, unfortunately, it is not a common practice among us. Therefore practitioners are not able to recall all their own medical records. We must know the therapeutic results to improve preceding decisions. Is has been hard to characterize the quality of medical care because of the lack of clinic data. Medical auditorship applies itself to define philosophical questions and to determine useful values in professional and scientific fields, available to any surgeon. Establishing an auditorship is first a need, second a choice. The evaluation of successful therapy and the rates of morbidity and mortality is the minimum we can expect in the immediate future.
