RESUMO

OBJECTIVES: To compare 3 mouthwashes: 0.20% chlorhexidine (CHX) with Anti-Discoloration System (ADS), 0.20% CHX and 0.12% CHX with 0.05% cetylpyridinium chloride (CPC), in terms of reduction of plaque and gingival bleeding and side effects. METHODS: Mild gingivitis patients were randomly divided into three Groups: they underwent professional oral hygiene and received instructions: oral rinse with 10 mL for 1', twice a day, 30' after tooth brushing, for 14 days. Primary outcomes were plaque and gingival bleeding, assessed with Plaque Control Record and Gingival Bleeding Index. Feedback questionnaire and spectrophotometer evaluated secondary outcomes: adverse events. Timing of the study was T0 (baseline), T1 (professional oral hygiene) and T2 (14th day after mouthwash use). RESULTS: Sixty-six patients were recruited, two patients dropped out, and 64 patients completed the study. PCR T1-T2 mean variation was 30.67 (SD = 15.22; 95% CI 23.55 to 37.80; P = 0.000), 19.93 (SD = 11.03; 95% CI 14.90 to 24.95; P = 0.000) and 16.24 (SD = 15.35; 95% CI 9.60 to 22.88; P = 0.000) respectively in Groups 0.2% CHX + ADS, 0.2% CHX and 0.12% CHX + CPC. GBI mean variation (T0-T2) was -9.82 (SD = 9.27; 95% CI -5.48 to 14.16; P = 0.000), -19.31 (SD = 11.33; 95% CI -14.15 to -24.47; P = 0.000) and -21.13 (SD = 12.56; 95% CI -15.70 to -26.56; P = 0.000) respectively in Groups 0.2% CHX + ADS, 0.2% CHX and 0.12% CHX + CPC. Statistical significance was found in lower efficacy of 0.2% CHX + ADS Group. Patients tolerated 0.12% CHX + CPC mouthwash better in bleeding perception (95.5%; P = 0.046), burning sensation (13.6%; P = 0.006), and mouthwash taste (100%; P = 0.000). Results on staining were no statistically significant (P = 0.106). CONCLUSIONS: Addition of CPC allows reduction of CHX percentage in mouthwash formulation while keeping equal efficacy and less side effects. ADS addition decreases CHX efficacy in reducing plaque and bleeding, while resulting more tolerated than CHX.

RESUMO

PURPOSE: Only a few reports in the literature have investigated the presence of ocular abnormalities in neurofibromatosis type 1 (NF-1) patients. The aim of this study was to evaluate the prevalence of ocular abnormalities in a large population of NF1 patients, focusing on the choroidal changes. METHODS: This study was conducted on 160 consecutive patients with NF1 and 106 sex- and age-matched healthy subjects (control). Each patient underwent a complete ophthalmological examination inclusive of best-corrected visual acuity, intraocular pressure measurement, slit-lamp biomicroscopy, indirect fundus biomicroscopy, and near-infrared reflectance (NIR) retinography by using the spectral domain OCT. Moreover, all patients underwent complete dermatological exam and 1.5-Tesla MRI scan of the brain to assess the presence of optic nerve gliomas. RESULTS: Choroidal abnormalities were detected in 97% of patients, with a positive predictive value of 100% and a negative predictive value of 96.4%. Interestingly, a small number of patients (4/160; 2.5%) showed Lisch nodules without choroidal abnormalities, whereas a larger number of patents (22/160; 13.75%) presented choroidal lesions in absence of Lisch nodules. None of the patients showed the absence of both choroidal lesions and Lisch nodules. The number of choroidal lesions increased with age (r = 0.364, p = 0.0001) and with the severity of pathology (r = 0.23, p = 0.003). Any statistically significant correlation between choroidal lesions, visual acuity, and intraocular pressure was observed. CONCLUSIONS: NIR imaging represents an in vivo, non-invasive, sensitive and reproducible exam to detect choroidal nodules in NF-1 patients, suggesting that choroidal changes may represent an additional diagnostic criteria for NF1.

RESUMO

OBJECTIVES: The aim of the study was to determine whether the release by macrophages of matrix metalloproteinase (MMP)-12 and vascular endothelial growth factor (VEGF) - leading to inflammation, matrix degradation and neoangiogenesis - represents an effective pathway that underlies aortic wall remodeling in Stanford type A acute aortic dissection (AAD). METHODS: Twenty-one consecutive patients with no genetic predisposition, with Stanford type A AAD were selected. In each patient, the levels of serum VEGF, MMP-12, serum interleukin (IL)-6, IL-8 and monocyte chemoattractant protein (MCP)-1 were evaluated using enzyme-linked immunosorbent assay. Ascending aortic specimens were collected for immunohistochemical identification of any presence of inflammatory infiltrate, VEGF and CD31 expression. RESULTS: A significant increase in serum VEGF (p = 0.044), MMP-12 (p = 0.007), IL-6 (p = 0.0001), IL-8 (p = 0.0001) and MCP-1 (p = 0.0001) levels was observed in the AAD group compared to the control group. Furthermore, all AAD samples were positive for VEGF in the tunica media and showed vessel growth and immune-inflammatory infiltrate. A large number of cases (62.79%) showed inflammation at the edge of the dissection and approximately half (51.42%) showed neovessels growing at the edge of the dissection. CONCLUSIONS: The results suggest that VEGF-mediated angiogenesis and matrix degradation play a role in AAD. Finally, we believe that MMP-12 should be considered a marker of AAD.

RESUMO

Primary hyperparathyroidism (PHPT) is usually associated with chronic constipation; however, its prevalence is not defined by standardized criteria. The aim of the study was to evaluate both the prevalence of chronic constipation, defined by the standardized Rome diagnostic criteria III (Rome III) in PHPT, and the effect of parathyroidectomy (PTx). Fifty postmenopausal PHPT patients and 50 sex- and age-matched controls were studied. Each patient underwent mineral metabolism biochemical evaluation and completed a questionnaire and a 2-week diary card about bowel habits. PHPT patients were reevaluated after 6 months. According to Rome III, 40 % of PHPT patients had chronic constipation compared with 12 % of controls (p = 0.0002). The only difference between constipated PHPT patients (group A, n = 20) and those without constipation (group B, n = 30) was higher mean PTH values (79.9 ± 18.7 ng/l vs. 65.4 ± 26.0 ng/l; p = 0.03), which predicted the presence of constipation (p = 0.004, OR 1.059, CI 1.011-1.059). Forty percent of PHPT patients had undergone PTx. In group A, constipation was resolved in 80 % of patients after PTx compared to none of the same group who had not undergone PTx (p = 0.0007). In group B, 17.6 % of patients who had not undergone PTx became, after 6 months, constipated. According to Rome III, a higher prevalence of chronic constipation in PHPT patients was observed compared with controls. PTH levels predicted constipation. A significant reduction of chronic constipation was reported following successful surgery.

RESUMO

STUDY OBJECTIVE: To describe the hysteroscopic findings in patients complaining of menorrhagia to establish any significant association between menorrhagia and benign/malignant intrauterine disorders. DESIGN: Prospective cohort study (Canadian Task Force classification II). SETTING: University La Sapienza, Rome, Italy. PATIENTS: One hundred eighteen premenopausal women undergoing office hysteroscopy for menorrhagia (group A) and 344 premenopausal patients undergoing office hysteroscopy for other indications (noncyclic abnormal uterine bleeding, infertility, ultrasonographic abnormalities, etc) (group B). INTERVENTIONS: Office hysteroscopy. MEASUREMENT AND MAIN RESULTS: Data on the prevalence of hysteroscopic findings (cervical polyps, endometrial polyps, submucous myomas, low-grade hyperplasia and high-grade hyperplasia/endometrial carcinoma) were compared between group A and group B. The total prevalence, as well as the prevalence of type 0 and type I myomas (totally or >50% intracavitary, respectively), and the mean number per patients with submucous myomas was significantly higher in group A compared with group B (p = .0001, p = .024, and p = .017, respectively). Multivariable logistic regression analysis showed a statistically significant association between age (odds ratio 4.15, 95% confidence interval 1.55-11.1 in the 40- to 49-year age group), presence of submucous myomas (odds ratio 2.76, 95% confidence interval 1.52-5.00), and menorrhagia. CONCLUSIONS: Menorrhagia seems to be associated with aging, the presence and number of submucous myomas, and with the degree of their intracavitary development.

RESUMO

To compare the visual evoked potential (VEP) responses of amblyopic eyes with VEP responses of sound eyes in amblyopic children. A study of 65 amblyopic children with pattern-reversal VEPs elicited by checkerboard stimuli with large, medium and small checks. The children were classified into three groups: Group A, 22 children with anisometropic amblyopia; Group B, 16 children with exotropic strabismic amblyopia; and Group C, 27 children with esotropic strabismic amblyopia. Visual acuity (VA) was significantly worse in the amblyopic eye as compared to the sound eye. However, no statistically significant difference was found between the amblyopic and sound eye of amblyopic children in the three groups for VEP P1 amplitude and latencies for any check sizes. VEP is a very important tool in understanding the complex amblyopic mechanism. Although the sound eye has superior VA, the absence of differences in VEP P1 amplitudes and latencies demonstrate the functional abnormality of the eye considered 'good'. More studies are necessary to explain why the sound eye in amblyopic children cannot be considered completely normal. Special attention should therefore be paid to amblyopic treatment, as patching can have a negative effect on the sound eye.

RESUMO

AIM: To analyze the prognostic value of maternal serum C-reactive protein (CRP) in predicting funisitis in patients with preterm premature rupture of membranes (pPROM). METHODS: 66 patients (gestational age 24-33 weeks) hospitalized 1-12 h after pPROM were enrolled. White blood cell count (WBC), platelet count (PLT) and plasma concentration of CRP were assessed every 3 days. Histological evidence of chorioamnionitis and funisitis was obtained post-partum. Receiver operating characteristic (ROC) curves were employed to evaluate the role of maternal CRP in predicting funisitis. RESULTS: Funisitis was found in 24 patients (36.3%); 42 patients (63.7%) without funisitis were considered as controls. PLT and WBC at admission and before delivery did not show significant differences and were not statistically different between the two groups. Patients with funisitis had significantly higher CRP levels both at admission to hospital and 24- 48 h before delivery. ROC curve analysis showed that CRP at admission (area under the curve: 0.671, p = 0.021) and before delivery (area under the curve: 0.737, p = 0.001) are predictive of funisitis. CONCLUSIONS: High maternal serum CRP levels (>20,000 µg/l) in pPROM patients at admission to hospital may be an early marker which indicates, with a good diagnostic performance, the presence of funisitis.

RESUMO

BACKGROUND: Postmortem and clinical studies have shown an early and prevalent involvement of the radiohumeral joint in primary and secondary arthritis of the elbow. The lateral resurfacing elbow (LRE) prosthesis has recently been developed for the treatment of lateral elbow arthritis. However, few data have been published on LRE results. MATERIALS AND METHODS: A prospective multicenter study was designed to assess LRE preliminary results. There were 20 patients (average age, 55 years). Preoperative diagnosis were primary osteoarthritis in 11 and post-traumatic osteoarthritis in 9. All patients underwent open debridement and LRE prosthesis. Patients were evaluated preoperatively and postoperatively with the Mayo Elbow Performance Score (MEPS), modified American Shoulder Elbow Surgeons (m-ASES) elbow assessment, and the Quick Disabilities of the Arm, Shoulder and Hand (Quick-DASH). Mean follow-up was 22.6 months. RESULTS: At the last follow-up, the mean improvement of MEPS and m-ASES was 35 (P = .001) and 34 (P = .001) respectively; the average Quick DASH decreased by 29 (P = .001). Average range of motion was improved by 35° (P = .001). MEPI results were excellent in 12 patients, good in 2, and fair and poor in 3 each. Mild overstuffing was observed in 5 patients, and an implant malpositioning in 3. The implant survival rate was 100%. CONCLUSION: LRE showed promising results in this prospective investigation. Most patients had an uneventful postoperative course and have shown a painless elbow joint, with satisfactory functional recovery at short-term follow-up. Further studies with longer follow-up are warranted.

RESUMO

OBJECTIVE: The aim of this study was to conduct a comparative study of semen quality in two large populations; one evaluated in 1992 and another in 2010, in order to evaluate any possible decline in male fertility due, at least in part, to environmental factors. MATERIAL AND METHODS: A total of 701 subjects in 1992 (TOTAL group 1992) and a total of 626 subjects in 2010 (TOTAL group 2010) were enrolled in our Andrology Unit. Each group was subdivided into 3 subgroups: Subfertile, Pathology and Control. Standard semen analysis was performed using the Superimposed Image Analysis System, according to WHO guidelines 1987 (for TOTAL group 1992) and WHO guidelines 1999 (for TOTAL group 2010). RESULTS: The mean values of sperm number (concentration/ml as well as the total ejaculate) and progressive motility were significantly higher in TOTAL group 2010 than TOTAL group 1992. Atypical forms in TOTAL group 1992 semen samples were significantly lower than TOTAL group 2010. The mean age of TOTAL Group 2010 was significantly higher compared with TOTAL Group 1992. In particular, the mean age gap was more evident in Subfertile subjects. CONCLUSIONS: In conclusion, environmental factors have not determined a significant decline in seminal parameters in the past 18 years.

RESUMO

BACKGROUND: Complex fracture-dislocations of the proximal ulna and radius include multiple anatomic lesions, the management of which is known to be demanding. Although several classifications have been proposed, none appear to be exhaustive, and most of them have neither therapeutic nor prognostic value. The purpose of this study was to design a comprehensive classification that may provide a guide for the operative management of these injuries. MATERIALS AND METHODS: The classification is aimed at identifying definite anatomic lesions, called the "main lesions," the presence of which can affect the prognosis and require peculiar treatments. The main lesions include (1) ulnar fracture (including its location with respect to the insertion of collateral ligaments and coronoid fracture), (2) radiohumeral dislocation, (3) proximal radioulnar dislocation, (4) radial fracture, (5) distal radioulnar joint and interosseous membrane lesion, and (6) humeral-ulnar dislocation. Intraobserver and interobserver reliability was assessed in 25 complex fracture-dislocations. Standard radiographs and computed tomography scans were analyzed by 3 independent observers. RESULTS: The main lesions were labeled by an alphanumeric system. Numbers 1 through 6 identified the type of ulnar fracture, and letters A through E indicated the dislocated joint or presence of a radial fracture. The direction of dislocation and the type of radial fracture were identified by Roman numerals, from I to III, placed after the letter. A κ value of 0.873 or greater resulted from intraobserver and interobserver evaluation. CONCLUSION: We created a comprehensive classification of complex fracture-dislocations of the elbow. The classification appeared to be reproducible and may represent a useful tool for the management of such difficult injuries.

RESUMO

Medulloblastoma is an aggressive brain malignancy with high incidence in childhood. Current treatment approaches have limited efficacy and severe side effects. Therefore, new risk-adapted therapeutic strategies based on molecular classification are required. MicroRNA expression analysis has emerged as a powerful tool to identify candidate molecules playing an important role in a large number of malignancies. However, no data are yet available on human primary medulloblastomas. A high throughput microRNA expression profiles was performed in human primary medulloblastoma specimens to investigate microRNA involvement in medulloblastoma carcinogenesis. We identified specific microRNA expression patterns which distinguish medulloblastoma differing in histotypes (anaplastic, classic and desmoplastic), in molecular features (ErbB2 or c-Myc overexpressing tumors) and in disease-risk stratification. MicroRNAs expression profile clearly differentiates medulloblastoma from either adult or fetal normal cerebellar tissues. Only a few microRNAs displayed upregulated expression, while most of them were downregulated in tumor samples, suggesting a tumor growth-inhibitory function. This property has been addressed for miR-9 and miR-125a, whose rescued expression promoted medulloblastoma cell growth arrest and apoptosis while targeting the proproliferative truncated TrkC isoform. In conclusion, misregulated microRNA expression profiles characterize human medulloblastomas, and may provide potential targets for novel therapeutic strategies.

RESUMO

PURPOSE: To evaluate the diagnostic accuracy of gadofosveset-enhanced magnetic resonance (MR) angiography in the assessment of carotid artery stenosis, with digital subtraction angiography (DSA) as the reference standard, and to determine the value of reading first-pass, steady-state, and "combined" (first-pass plus steady-state) MR angiograms. MATERIALS AND METHODS: This study was approved by the local ethics committee, and all subjects gave written informed consent. MR angiography and DSA were performed in 84 patients (56 men, 28 women; age range, 61-76 years) with carotid artery stenosis at Doppler ultrasonography. Three readers reviewed the first-pass, steady-state, and combined MR data sets, and one independent observer evaluated the DSA images to assess stenosis degree, plaque morphology and ulceration, stenosis length, and tandem lesions. Interobserver agreement regarding MR angiographic findings was analyzed by using intraclass correlation and Cohen kappa coefficients. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated by using the McNemar test to determine possible significant differences (P < .05). RESULTS: Interobserver agreement regarding all MR angiogram readings was substantial. For grading stenosis, sensitivity, specificity, PPV, and NPV were, respectively, 90%, 92%, 91%, and 91% for first-pass imaging; 95% each for steady-state imaging; and 96%, 99%, 99%, and 97% for combined imaging. For evaluation of plaque morphology, respective values were 84%, 86%, 88%, and 82% for first-pass imaging; 98%, 97%, 98%, and 97% for steady-state imaging; and 98%, 100%, 100%, and 97% for combined imaging. Differences between the first-pass, steady-state, and combined image readings for assessment of stenosis degree and plaque morphology were significant (P < .001). CONCLUSION: Gadofosveset-enhanced MR angiography is a promising technique for imaging carotid artery stenosis. Steady-state image reading is superior to first-pass image reading, but the combined reading protocol is more accurate.

RESUMO

Objectives: To detect on computed tomography (CT) brain scans the trajectories of normal and abnormal ventricular enlargement during aging. Methods: For each 1-year age cohort, we assessed in 3,193 axial CT scans the Evans' index (EI) in the anterior frontal horns and the parieto-occipital (POR) and temporal ratio (TR) in the posterior and inferior horns. Cut-off values for abnormal enlargement were based on previous clinical studies. Results: The mean age associated with normal linear measures was 71 years. Values for all three measures increased with age, showing a linear relationship below-but not above-each cut-off value. The mean age of participants with abnormal enlargement on CT progressed from 79 years for EI to 83 years for POR to 87 years for TR. These results suggested that ventricular dilatation progresses in an age-location relationship. First comes enlargement of the frontal horns (13.8% of scans), followed by the parieto-occipital horns (15.1% of scans) and then temporal horn enlargement (6.8% of scans). Scans from men displayed abnormal values earlier than scans from women (on average 6 years). Risk increased 5.1% annually for abnormal EI, 9.0% for abnormal POR, and 11% for abnormal TR (all p < 0.001). The most frequent agreement between categories (normal-abnormal) for values of neuroimaging measures was identified for POR-TR. Conclusion: The results of this large radiological study suggest that the ventricular system enlarges progressively during aging, and in a subset of patients follows an abnormal consecutive geometric dilatation, influenced by age and sex.

RESUMO

We have compiled a complete list of new marine molluscan taxa introduced by Tommaso Allery Di Maria, Marquis of Monterosato (1841-1927). The dates of publication of every single work have been checked against available evidence, and an updated bibliography is also presented. Finally, the type material of all marine taxa expected to be in the collection Monterosato (presently preserved in the Museo Civico di Zoologia in Rome) has been searched in the main collection, and all retrieved specimens have been catalogued. A large majority of the material has been found, representative specimens of each taxon have been illustrated, and remarks on nomenclature and taxonomy have been provided yielding 42 new synonymies, 46 nominal taxa rediscovered, and 6 new combinations.

RESUMO

BACKGROUND: Renal dysfunction in end-stage liver disease (ESLD) results from systemic conditions that affect both liver and kidney with activation of vasoconstrictor systems. In this setting, estimated glomerular filtration rate (eGFR) may undergo variations often outside Kidney Disease Improving Global Outcomes criteria for acute kidney injury (AKI) diagnosis, whose meaning is not clear. The aim of this study was to evaluate eGFR variations in ESLD outpatients listed for liver transplant (liver Tx) and the association with post-Tx outcome. METHODS: Fifty-one patients with ESLD were retrospectively evaluated from listing to transplant (L-Tx time), intraoperatively (Tx time), and up to 5 years post-Tx time. Variations between the highest and the lowest eGFR occurring in more than 48 hours, not satisfying Kidney Disease Improving Global Outcomes guideline, were considered as fluctuations (eGFR-F). Fluctuations of eGFR greater than 50% were defined as eGFR drops (DeGFR). Early graft dysfunction, AKI within 7 days, chronic kidney disease, and short- and long-term patient survivals were considered as outcomes. RESULTS: All patients presented eGFR-F, whereas DeGFR were observed in 18 (35.3%) of 51 (DeGFR+ group). These patients presented higher levels of Model for End-stage Liver Disease score, pre-Tx bilirubin and significantly greater incidence of post-Tx AKI stages 2 to 3 compared with patients without drops (DeGFR-). DeGFR was the only independent predictive factor of the occurrence of post-Tx AKI. The occurrence of AKI post-Tx was associated with the development of chronic kidney disease at 3 months and 5 years post-Tx. CONCLUSIONS: Drops of eGFR are more frequently observed in patients with a worse degree of ESLD and are associated with a worse post-Tx kidney outcome.

Twenty consecutive rheumatoid arthritis (RA) patients (mean age 50.4 +/- 10.5 years; 17 females; mean disease duration 5.78 +/- 3.75 years) enrolled for tumor necrosis factor-alpha (TNF-alpha) blockers therapy (10 infliximab and 10 etanercept) were selected. Before starting therapy, 3 and 6 months thereafter all patients were evaluated for disease activity score (DAS), erythrocyte sedimentation rate (ESR), serum levels of C-reactive protein (CRP), interleukin-6 (IL-6), nerve growth factor (NGF), and brain-derived neurotrophic factor (BDNF). After 3 and 6 months a significant reduction in DAS, ESR, CRP, and IL-6 was observed, whereas no significant differences of NGF and BDNF serum levels were found. These preliminary results confirm that TNF-alpha blockers significantly improve disease activity and inflammation in RA; nevertheless further studies are needed to explain the mechanisms regulating NGF and BDNF release in RA patients treated with TNF-alpha blockers.

RESUMO

Cardiac calcifications are a frequent finding in hemodialysis for chronic renal failure. Several factors may play a role in the intimal and medial calcification of coronary arteries such as age and some known atherogenetic factors. In addition, Fetuin-A has been proposed as a protective agent through solubilization of calcium phosphate salt. Fetuin-A is also a marker of inflammatory-nutritional state, and its changes could be an expression of this condition. The aim of this cross-sectional study is to evaluate the relative importance of risk factors of calcifications with special regard to Fetuin-A. The study was conducted with 132 hemodialysis patients. They were subjected to multislice computed tomography for evaluation of calcium deposits in the heart. In addition, the patients were sampled for evaluation of calcium-phosphate parameters, lipid profile, nutritional and inflammatory markers, and also Fetuin-A. There was a wide variability of the extent of calcium deposits expressed as Agatston score, with only 9.3% of patients without calcifications. Age, hemodialysis age, sex, calcium-phosphate parameters, and lipid profile were important risk factors, together with nutritional and inflammatory status of the patients. An inverse correlation between coronary calcium score and Fetuin-A emerged from a multiple regression analysis. However, there was no significant difference in serum Fetuin-A among different grades of calcium score. By dividing the patients in tertiles of serum Fetuin-A, an association between low levels of Fetuin-A and high calcification score was found. Fetuin-A as dependent variable was strictly linked to prealbumin serum levels. In addition, there was a clear link between cardiac calcification scores and inflammatory-nutritional markers. Serum calcium and treatment with calcitriol emerged as predictive variables of coronary score.Fetuin-A could be involved in the process of calcification both in the case of markedly low serum levels, due to decreased prevention of calcium phosphate precipitation, and also as a marker of inflammation, a well-known risk factor of atherogenesis. Treatment with intravenous calcitriol could marginally enhance cardiac calcifications, probably through its hypercalcemic effect.

RESUMO

Ventricular enlargement in normal aging frequently forces the radiological diagnosis of hydrocephalus, but the reliability of Evans' index as a radiological marker of abnormal ventricular enlargement (values > 0.30) during aging is not assessed. Here we analyze ventricular size during aging and the reliability of Evans' index as a radiological marker of abnormal ventricular enlargement. We calculated Evans' index in the axial Computed Tomography scans of 1221 consecutive individuals (aged 45-101 years) from an emergency department. Stratified analysis of one-year cohorts showed that the mean Evans' index value per class was invariably < 0.30. Roughly one out five Computed Tomography scans was associated with Evans' index values > 0.30 and Evans' index values increased with age. The risk of having an Evans' index value > 0.30 increased by 7.8% per year of age (p < 0.001) and males were at 83.9% greater risk than females (p < 0.001). Overall, this study shows that normal aging enlarges the ventricular system, but never causes abnormal ventricular enlargement. Evans' index values > 0.30 should reflect an underlying neurological condition in every individual.

RESUMO

OBJECTIVE: The prevalence of abdominal aortic calcification (AAC) in primary hyperparathyroidism (PHPT) is unknown. We assessed both prevalence and severity of AAC in PHPT postmenopausal women. METHODS: In this study 70 PHPT postmenopausal women and 70 age- and sex-matched controls were enrolled. Each participant underwent biochemical evaluation, lateral spine radiograph, bone mineral density (BMD) measurement (lumbar, femoral, radial sites), and kidney ultrasound. Lateral lumbar films were analyzed in the region of L1-L4 vertebrae and the Kauppila score (a semi-quantitative grading system) was used to assess the severity of AAC. RESULTS: There were no differences regarding demographic and cardiovascular risk factors in the two groups. PHPT patients had higher prevalence of kidney stones (30% vs 7%, P=0.0008) and lower radial BMD values (0.558±0.071 vs 0.588±0.082 g/cm(2), P<0.05) compared with controls. PHPT patients showed higher prevalence of AAC (31 vs 18, P=0.03), with more severe calcifications (Kauppila score 7.35±6.1 vs 5.05±3.5, P=0.007). PHPT patients with AAC were older and had been suffering from the disease for a longer period compared with those without ACC. Moreover, PHPT patients with severe AAC had mean higher serum parathyroid hormone levels compared with patients with moderate or mild calcifications. In PHPT patients with AAC, multiple regression analysis, adjusted for age and years since diagnosis, showed that only parathyroid hormone significantly correlated with Kauppila score. CONCLUSION: We found a higher prevalence and severity of AAC in PHPT related to parathyroid hormone effect.
