Idiopathic spinal epidural hematoma in patients with sudden paraplegia: A case report

Introduction. Spontaneous spinal epidural hematoma (SEH) represents 0.3-0.9% of spinal epidural space-occupying lesions, and most surgeons advocate aggressive and early surgical intervention. In. this paper we describe a patient with SEH with sudden paraplegia. Case report. This 30-year-old man had experienced one prior episode of sudden dorsal pain two days before the current admission and while he waited medical attendance, his legs suddenly became weak, and immediately afterwards, he became completely paraplegic in minutes. The patient had complete paraplegia, analgesia below the T4 level and urinary retention. He had no anticoagulant agent and no coagulopathic disease. He was submitted to computerized tomography that demonstrated a dorsally located epidural hematoma extending from the T3 to the T6 level with spinal cord compression. A laminectomy from T3 to T7 was performed four hours after the onset of the symptom. In postoperative time the patient presented the partial sensorial recovery and motor force grade II. The patient was directed to a neurorehabilitation program and in the last medical evaluation he presented recovery for motor grade III-IV without pain. Conclusion. The SHE is rare, with severe neurological consequences for patients and early surgical treatment persist as essential for motor recovery.

Sex, Clinical Symptoms, and Angiographic Findings in Patients With Diabetes Mellitus and Coronary Artery Disease (from the Bypass Angioplasty Revascularization Investigation [BARI] 2 Diabetes Trial)

Previous studies have reported differences in presenting symptoms and angiographic characteristics between women and men undergoing evaluation for suspected coronary artery disease (CAD). We examined the relation between symptoms and extent of CAD in patients with type 2 diabetes mellitus and known CAD enrolled in the Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial. Of 1,775 patients (533 women, 30%, and 1,242 men, 70%), women were more likely than men to have angina (65% vs 56%, p < 0.001) or an atypical angina/anginal equivalent (71% vs 58%, p < 0.001). More women reported unstable angina (17% vs 13%, p = 0.047) or were in a higher Canadian Cardiology Society class compared to men (Canadian Cardiology Society classes II to IV 78% vs 68%, p = 0.002). Fewer women than men had no symptoms (14% vs 22%, p < 0.001). Women had a lower mean myocardial jeopardy index (42.5 +/- 24.3 vs 47.9 +/- 24.3, p < 0.001), smaller number of total significant lesions (2.3 +/- 17 1.7 vs 2.7 +/- 1.8, p < 0.001), and fewer jeopardized left ventricular regions (p < 0.001 for distribution) or long-term occlusions (29% vs 42%, p < 0.001). After adjustment for relevant covariates, the odds of having CAD symptoms were still higher in women than men (odds ratio for angina 1.31, 95% confidence interval 1.02 to 1.69; odds ratio for atypical angina 1.52, 95% confidence interval 1.17 to 1.96). In conclusion, in a high-risk group of patients with known CAD and diabetes mellitus, women were more symptomatic than men but had less obstructive CAD. These data suggest that factors other than epicardial CAD severity influence symptom presentation in women in this population. (C) 2011 Elsevier Inc. All rights reserved.

Otolaryngology and Speech Therapy evaluation in the assessment of oropharyngeal dysphagia: a combined protocol proposal

Dysphagia is a symptom associated with an array of anatomical and functional changes which must be assessed by a multidisciplinary team to guarantee optimal evaluation and treatment, preventing potential complications. Aim: The aim of the present study is to present the combined protocol of clinical and swallowing videoendoscopy carried by ENT doctors and speech therapists in the Dysphagia Group of the ENT Department - University Hospital. Materials and Methods: Retrospective study concerning the use of a protocol made up of patient interview and clinical examination, followed by an objective evaluation with swallowing videoendoscopy. The exam was performed in 1,332 patients from May 2001 to December 2008. There were 726 (54.50%) males and 606 (45.50%) females, between 22 days and 99 years old. Results: We found: 427 (32.08%) cases of normal swallowing, 273 (20.48%) mild dysphagia, 224 (16.81%) moderate dysphagia, 373 (27.99%) severe dysphagia and 35 (2.64%) inconclusive exams. Conclusion: The combined protocol (Otolaryngology and Speech Therapy), is a good way to approach the dysphagic patient, helping to achieve early and safe deglutition diagnosis as far as disorder severity and treatment are concerned.

Uveitis in celiac disease with an excellent response to gluten-free diet: third case described

To describe the case of a patient with celiac disease who achieved a complete response to a gluten-free diet. A 28-year-old woman presented with diarrhea, oral ulcers, and refractory uveitis of 2.5-years duration. She was treated with prednisone, mydriatic drops, and infliximab with no response. She was referred to our hospital at which point her previous diagnosis of uveitis was confirmed; she was also diagnosed with right-sided sacro-iliitis. The patient did not have arthritis or any skin conditions. Three tests for fecal parasites and a fecal leukocyte were negative. Endoscopy revealed atrophic appearance of the duodenal mucosa. Biopsy showed atrophy of the duodenal villi with intra-epithelial lymphocytes, hyperplasia of the crypts, and chronic inflammatory infiltrate. The search for antiendomysial antibody was > 1/1,280. The patient was started on a gluten-free diet and after 3 months demonstrated significant improvement of gastrointestinal symptoms and uveitis, as well as a reduction of antiendomysial antibodies (1/80). After 6 months, there was complete remission of gastrointestinal symptoms and total control of uveitis. The antiendomysial antibody was negative at that time. Clinical uveitis as a manifestation of celiac disease has been described in only two cases in the literature. This case study is the third to demonstrate that uveitis is a clinical symptom that can be addressed in patients with celiac disease.

Neck Nerve Trunks Schwannomas: Clinical Features and Postoperative Neurologic Outcome

Objectives/Hypothesis: To analyze clinical and epidemiological features of neck nerve schwannomas, with emphasis on the neurologic outcome after surgical excision sparing as much of nerve fibers as possible with enucleation technique. Study Design: Retrospective study. Methods: Review of medical records from 1987 to 2006 of patients with neck nerve schwannomas, treated in a single institution. Results: Twenty-two patients were identified. Gender distribution was equal and age ranged from 15 to 61 years (mean: 38.6 years). Seven vagal, four brachial plexus, four sympathetic trunk, three cervical plexus, and two lesions on other sites could be identified. Most common symptom was neck mass. Local or irradiated pain also occurred in five cases. Median growing rate of tumors was 3 mm per year. Nerve paralysis was noted twice (a vagal schwannoma and a hypoglossal paralysis compressed by a vagal schwannoma). Different techniques were employed, and seven out of nine patients kept their nerve function (78%) after enucleation. No recurrence was observed in follow-up. Conclusions: Schwannomas should be treated surgically because of its growing potential, leading to local and neural compression symptoms. When possible, enucleation, which was employed in 10 patients of this series, is the recommended surgical option, allowing neural function preservation or restoration in most instances. This is especially important in the head and neck, where denervation may have a significant impact on the quality of life.

Urodynamic evaluation of patients with lower urinary tract symptoms and small prostate volume

Introduction: The relevance of prostate size in the pathophysiology of lower urinary tract symptoms (LUTS) is controversial. We evaluated the urodynamic findings in patients with LUTS and small prostate volumes. Materials and Methods: 84 patients aged >= 50 years with LUTS and prostates < 40 ml were evaluated. All had an International Prostate Symptom Score (IPSS) >= 8. Average age was 62.0 +/- 8.1 years. We evaluated the impact of bladder outlet obstruction (BOO) and detrusor overactivity (DO) on the voiding symptoms and urodynamic findings. Results: Mean prostate volume was 29.2 +/- 7.2 ml and mean IPSS was 13.5 +/- 4.6. BOO was the main finding, affecting 42 (50.0%) patients, followed by detrusor underactivity (DU) in 41 (48.8%) and DO in 28 (33.3%) patients. Patients without BOO were significantly older than the obstructed (64.0 +/- 8.8 and 60.1 +/- 6.9 years, respectively; p = 0.026) and had an increased prevalence of DU (76.2 and 21.4%, respectively; p < 0.001). Comparison of patients with and without DO showed reduced bladder capacity and compliance in the DO group (p < 0.001). No other comparisons were significant. Conclusion: Half of the patients with LUTS and small prostates are not obstructed and may have DO or decreased detrusor contractility as the basis for their voiding symptoms. Our results emphasize the value of urodynamics in this population, especially when invasive treatments are being considered. Copyright (c) 2008 S. Karger AG, Basel.

Urodynamic evaluation in diabetic patients with prostate enlargement and lower urinary tract symptoms

Introduction: Lower urinary tract symptoms ( LUTS) are common in men over 50 years of age due to prostate enlargement. Diabetes mellitus is also more prevalent in this group. LUTS may result from bladder outlet obstruction ( BOO) secondary to prostate enlargement or bladder dysfunction secondary to diabetes or even from a combination of both. Objectives: The objective of this study was to determine the prevalence of BOO and other urodynamic abnormalities in diabetic patients with LUTS and enlarged prostate. A secondary objective was to assess the predictive value of non-invasive tests for BOO diagnosis in this group of patients. Patients and Methods: 50 consecutive diabetic patients with enlarged prostate and LUTS were evaluated by the International Prostate Symptom Score ( IPSS), ultra sonography and urodynamics. BOO diagnosis was based on pressure/ flow measurements according to the International Continence Society`s standards. Results: Of the 50 patients in the study, 23 ( 46%) had BOO. There was no correlation between the IPSS, uroflowmetry, post- voiding residual urine or prostate volume and the presence of BOO ( p > 0.05). Conclusions: There is a relatively low prevalence of BOO in diabetic patients with prostate enlargement and LUTS. Non- invasive tests did not allow the identification of these subjects. Only urodynamic evaluation is able to determine symptom etiology. Copyright (c) 2008 S. Karger AG, Basel.

The prevalence of erectile dysfunction among Brazilian men screened for prostate cancer

OBJECTIVE To determine the prevalence of erectile dysfunction (ED) in a large cohort of Brazilian men who were screened for prostate cancer, and to determine risk factors in this population, as there are large cultural differences among countries in reporting the frequency of ED, and it is likely that the prevalence of ED among men screened for prostate cancer cannot be generally applied across countries. SUBJECTS AND METHODS The analysis focused on the baseline characteristics of 1008 consecutive South American men from Brazil with no known prostate disease who had routine screening for prostate cancer by urologists. The variables analysed were patient age, urinary symptoms, patient health-related quality of life (HRQL), prostate-specific antigen (PSA) levels, prostate volume and erectile function. To assess lower urinary tract symptoms (LUTS) and HRQL, we used the American Urological Association symptom score and its appended eighth question, respectively. Benign prostatic hyperplasia was defined as a prostate volume of > 30 g. Sexual function was assessed using the five-item version of the International Index of Erectile Function questionnaire. Thus, ED was considered to absent for scores of 22-25, mild for 17-21, mild to moderate for 12-16, moderate for 8-11, or severe for 5-7. Obesity was defined by calculating the body mass index (BMI), and categorized as underweight (< 18.5 kg/m

Basilar artery occlusive disease in stroke survivors in a multiethnic population

Objectives: To describe clinical, radiological findings, and outcome in a multiethnic population of stroke survivors with basilar artery occlusive disease (BAOC). Methods: Forty patients with infarcts in the basilar artery (BA) territory, alive 30 days after the ictus, participated in the study. BA stenosis (>50%) or occlusion was shown by magnetic resonance or digital subtraction angiography in all patients. Demographical, clinical and radiological characteristics were described. Modified Rankin Scale (MRS) scores at 30 days and 6 months after the ischemic event were evaluated. Association between demographical, clinical, radiological features and outcome were analyzed with Chi-square and Fisher`s exact tests. MRS scores at 30 days and 6 months were compared with the Wilcoxon test. Results: Sixty percent of the patients were men, and 33% were Afro-Brazilian. Mean age was 55.8 +/- 12.9 years. Most (90%) had multiple vascular risk factors. Stroke was preceded by TIA in 48% of the patients, and 80% had a history of arterial hypertension. The most common neurological symptom was vertigo/dizziness (60%) and the sign, hemiparesis (60%). Most of the infarcts were located in the pons (85%) and the BA middle third was the most frequently affected segment (33%). BA occlusion occurred in 58% of the patients. More severe vascular occlusive lesions were present in Whites (p = 0.002) and in patients with involvement of the middle third of the BA (p = 0.021). Large-artery atherosclerosis was the most common stroke etiology (88%) and was more frequent in older patients (p < 0.001). Most patients were treated with anticoagulation. MRS scores improved significantly at 6 months (p < 0.001): at this time, 78% of the patients had MRS scores between 0 and 2. Conclusions: We observed different results compared with other series: greater proportion of Afro-descendents, higher frequency of atherosclerosis and BA occlusion. Rates of preceding TIAs and good outcome at 6 months were similar to previously published data. These results represent a step forward towards understanding BAOC in a multiethnic context.

Xerostomia in Sjogren`s syndrome and lupus erythematosus: a comparative histological and immunofluorescence study of minor salivary glands alterations

Background: Xerostomia is a symptom that can be triggered by chronic diseases such as Sjogren`s syndrome (SS) and lupus erythematosus (LE). Many authors regard most cases of salivary hypofunction in LE to secondary SS. Others believe that salivary changes in patients with LE might reflect a multisystem presentation of the disease. The present study compared histopathological and direct immunofluorescence (DIF) alterations in salivary glands of patients with xerostomia and diagnosis of LE or SS. Methods: Twenty-eight salivary gland biopsies from patients with xerostomia and diagnosed with LE or SS were submitted to histopathological and DIF exams. Results: From the 28 patients, 16 had SS and 12 had LE. In SS, a moderate to intense sialadenitis was detected, with infiltration and destruction of excretory salivary ducts. In LE, mild/moderate sialadenitis with thickening and hyalinization of the ductal basement membrane was observed. DIF revealed that 50% of SS patients presented intercellular ductal IgA deposits, whereas 58% of LE patients showed deposits of IgG in the ductal basement membrane. Conclusions: Alterations in salivary glands of LE patients may be a specific manifestation of the disease (lupus sialadenitis), reflecting its multisystemic presentation, instead of an association of secondary SS and LE.

The effects of plantar fasciitis and pain on plantar pressure distribution of recreational runners

Background: Plantar fasciitis is the third most frequent injury in runners. Despite its high prevalence, its pathogenesis remains inconclusive. The literature reports overload as the basic mechanism for its development. However, the way that these plantar loads are distributed on the foot surface of runners with plantar fasciitis and the effects of pain on this mechanical factor has not yet been investigated. Therefore, the aim of this study was to evaluate and compare the plantar pressure distributions during running in runners with symptom or history of plantar fasciitis and runners without the disease. Methods: Forty-five recreational runners with plantar fasciitis (30 symptomatic and 15 with previous history of the disease) and 60 runners without plantar fasciitis (control group) were evaluated. Pain was assessed by a visual analogue scale. All runners were evaluated by means of the Pedar system insoles during running forty meters at a speed of 12(5%) km/h, using standard sport footwear. Two-way ANOVAS were employed to investigate the main and interaction effects between groups and plantar areas. Findings: No interaction effects were found for any of the investigated variables: peak pressure (P=0.61), contact area (P=0.38), contact time (P=0.91), and the pressure-time integral (P=0.50). Interpretation: These findings indicated that the patterns of plantar pressure distribution were not affected in recreational runners with plantar fasciitis when compared to control runners. Pain also did not interfere with the dynamic patterns of the plantar pressure distributions. (C) 2010 Elsevier Ltd. All rights reserved.

Effects of Aerobic Training on Psychosocial Morbidity and Symptoms in Patients With Asthma A Randomized Clinical Trial

Background: Asthma symptoms reduce patients daily activities, impair their health-related quality of life (HRQoL), and increase their reports of anxiety and depress, all of which seem to be related to a decrease in asthma control. Aerobic exercise training is known to improve aerobic fitness and reduce dyspnea in asthmatics; however, its effect in reducing psychologic distress and symptoms remains poorly understood. We evaluated the role of an aerobic training program in improving HRQoL (primary aim) and reducing psychologic distress and asthma symptoms (secondary aims) for patients with moderate or severe persistent asthma. Methods: A total of 101 patients were randomly assigned to either a control group or an aerobic training group and studied during the period between medical consultations. Control group patients (educational program plus breathing exercises) (n = 51) and training group patients (educational program plus breathing exercises plus aerobic training) (n = 50) were followed twice a week during a 3-month period. HRQoL and levels of anxiety and depression were quantified before and after treatment. Asthma symptoms were evaluated monthly. Results: At 3 months, the domains (physical limitations, frequency of symptoms, and psychosocial) and total scores of HRQoL, significantly improved only in the training group patients (P < .001); the number of asthma-symptom-free days and anxiety and depression levels also significantly improved in this group (P < .001). In addition, a linear relationship between improvement in aerobic capacity and the days without asthma symptoms was observed (r = 0.47; P < .01). Conclusions: Our results suggest that aerobic training can play an important role in the clinical management of patients with persistent asthma. Further, they may be especially useful for patients with higher degrees of psychosocial distress.

Effects of Aerobic Training on Airway Inflammation in Asthmatic Patients

MENDES, F. A. R., F. M. ALMEIDA, A. CUKIER, R. STELMACH, W. JACOB-FILHO, M. A. MARTINS, and C. R. F. CARVALHO. Effects of Aerobic Training on Airway Inflammation in Asthmatic Patients. Med. Sci. Sports Exerc., Vol. 43, No. 2, pp. 197-203, 2011. Purpose: There is evidence suggesting that physical activity has anti-inflammatory effects in many chronic diseases; however, the role of exercise in airway inflammation in asthma is poorly understood. We aimed to evaluate the effects of an aerobic training program on eosinophil inflammation (primary aim) and nitric oxide (secondary aim) in patients with moderate or severe persistent asthma. Methods: Sixty-eight patients randomly assigned to either control (CG) or aerobic training (TG) groups were studied during the period between medical consultations. Patients in the CG (educational program + breathing exercises; N = 34) and TG (educational program + breathing exercises + aerobic training; N = 34) were examined twice a week during a 3-month period. Before and after the intervention, patients underwent induced sputum, fractional exhaled nitric oxide (FeNO), pulmonary function, and cardiopulmonary exercise testing. Asthma symptom-free days were quantified monthly, and asthma exacerbation was monitored during 3 months of intervention. Results: At 3 months, decreases in the total and eosinophil cell counts in induced sputum (P = 0.004) and in the levels of FeNO (P = 0.009) were observed after intervention only in the TG. The number of asthma symptom-free days and (V) over dotO(2max) also significantly improved (P < 0.001), and lower asthma exacerbation occurred in the TG (P < 0.01). In addition, the TG presented a strong positive relationship between baseline FeNO and eosinophil counts as well as their improvement after training (r = 0.77 and r = 0.9, respectively). Conclusions: Aerobic training reduces sputum eosinophil and FeNO in patients with moderate or severe asthma, and these benefits were more significant in subjects with higher levels of inflammation. These results suggest that aerobic training might be useful as an adjuvant therapy in asthmatic patients under optimized medical treatment.

Involvement of the central nervous system in patients with dengue virus infection

The findings of a neurological evaluation in 85 patients with confirmed, acute, dengue virus infection are described. Signs of central nervous system involvement were present in IS patients (21.2%). The most frequent neurological symptom was mental confusion. The frequency of neurological involvement did not differ between patients with primary and secondary dengue infection, and the prevalence of central nervous system involvement in dengue fever and dengue hemorrhagic fever also did not differ significantly. The presence of CNS involvement did not influence the prognosis of dengue infection. Dengue viral CSF RNA was found in 7 of 13 patients submitted to a spinal tap, the CSF viral load being less than 1000 copies/ml. PCR was negative in serum samples obtained from three patients on the same day as the CSF samples, suggesting that the dengue virus actively enters the CNS and that the presence of the virus in the CNS does not result from passive crossing of the blood-brain barrier.

Histopathological changes induced by extracts from the tissue covering the stingers of Potamotrygon falkneri freshwater stingrays

Pain is the most conspicuous symptom observed in patients wounded by stingrays, and skin necrosis is common in accidents by freshwater stingrays. The extract from the stinger integumentary tissue of Potamotrygon falkneri containing toxic components (venom) was tested for its ability to induce histopathological changes in the dorsal skin of mice at different times. 3-6 h after injection, foci of necrosis in isolated basal epidermal cells were observed. Full coagulative necrosis of the skin, subcutaneous tissue and skeletal muscle was evident as soon as 24 h after venom exposure, with a clear demarcation from the normal skin. After 48 h, round collections of necrotic cells start to coalesce originating extensive skin necrotic plaques that detach from viable tissue after 72-96 h. Inflammatory infiltrate was observed after 6 h, but was always mild. Acute vascular thrombosis was rare, and hemorrhage was not present at any time. Superficial bacterial infection was present in two of the examined cases. In conclusion, the venom of P. falkneri is responsible for the development of an early necrosis with mild inflammatory reaction, probably due to direct action of the venom. The severe local damage is probably worsened by the mechanical trauma caused by the stinger. (c) 2010 Elsevier Ltd. All rights reserved.
