RESUMO
Carpal tunnel syndrome (CTS) is the most frequent entrapment neuropathy. Patients commonly experience neuropathic pain, leading them to seek medical advice. However, other symptoms experienced in patients with CTS, such as paresthesia, dysesthesia and allodynia, classed as positive sensory symptoms (PSS), are often under-reported. In the present study, patients with surgically-managed CTS were observed pre- and post-surgery to evaluate PSS, using the symptoms scale component of the Boston Carpal Tunnel Questionnaire (BCTQ) and the Sensory Frequency of Symptoms Scale. In total, 19 patients were included in the present study, with 79% female patients, and a mean age of 54±10.59 years. In addition, the mean follow-up was 63±29.91 months. The results of the present study revealed a pre-surgery BCTQ score of 3.52±0.63 and a post-surgery BCTQ score of 1.58±0.61. Notably, improvements in pain were observed, at 7.7±2.26 pre-surgery compared with 1.65±2.88 post-surgery. Compared with pre-surgery, post-surgery paresthesia scores were reduced from 2.94±0.82 to 0.47±0.45, dysesthesia scores were reduced from 2.52±0.84 to 0.47±0.39 and allodynia scores were reduced from 0.63±0.75 to 0.26±0.47. In conclusion, the results of the present study demonstrated that median nerve decompression ameliorated CTS symptoms, such as paresthesia and dysesthesia. However, further investigations are required to verify the benefits of surgery in relieving allodynia.
RESUMO
BACKGROUND: There are no articles that aim to evaluate the specific role of surgical decompression on the recovery of pain and positive sensory symptoms (PSS) in patients with brachial plexus neuropathy (BPN), as well as the relationship between pain and frequency of sensory manifestations. METHODS: A prospective before and after study was performed, considering the pain intensity through the visual analogue scale (VAS), and the frequency of PSS through a proposed new scale: Sensory Frequency of Symptoms Scale (SFSS). To compare the patients before and after the intervention, a paired T-test, a Wilcoxon signed-rank test, and Cohen's D test were made, coupled with a Spearman analysis in order to establish the relationship between pain and PSS. RESULTS: Sixteen patients were included in the study, the clinical evaluation showed changes in pain according with VAS, going from a mean preoperative state of 8.19 to 1.31 after surgery, showing significant changes (84%, p < 0.00006, Δ = 2.776). Within the PSS, a significant decrease was observed in paresthesias (74%, p < 0.0001, Δ = 1.645), dysesthesias (80%, p < 0.002, Δ = 1.453), and allodynia (70%, p = 0.031, Δ = 0.635). Conversely, the preoperative correlation analysis between pain and dysesthesias/allodynia showed a low and non-significant relationship (R < 0.4, p > 0.05). CONCLUSIONS: Surgical decompression is an effective technique for the relief of pain and sensory manifestations in adult patients with BPN of compressive origin. No relationship was observed between pain and dysesthesias/allodynia. Therefore, during clinical evaluation, they should be considered as independent manifestations, highlighting the need to validate new scales.

Objective: To evaluate the usefulness of surgical neurolysis for neuropathic pain relief in patients with posttraumatic brachial plexus injury (BPI). Methods: A prospective, longitudinal, nonrandomized, self-controlled before and after study was performed to evaluate the pain changes according to their intensity using the Visual Analogue Scale (VAS), and the sensory recovery after surgery using the British Medical Research Council (BMRC) scale for sensory recovery. To establish significant changes, a paired T-test was performed, and in order to determine the magnitude of these changes, an effect size was measured. α = 0.05. Results: Ten patients were included with an average follow-up of 61.9 ± 53.62 months. The main mechanism of injury was vehicular trauma (70%). A significant decrease in pain after the surgical intervention was observed resulting from an average preoperative state according to VAS of 8.4 ± 1.58, to a postoperative state of 3.4 ± 3.27 (59.52%, p = 0.005, Δ = 1.572), added to a mean sensory improvement (25%) from 2.8 ± 1.62 to 3.5 ± 0.97 after surgery according to BMRC, without statistically significant changes (p=0.062), showing a moderate effect size (Δ = 0.413). Almost all patients showed improvement in the continuous and paroxysmal pattern of pain. No postoperative complications were observed. Discussion. These results suggest that in cases of BPI that originates from a compressive syndrome secondary to the posttraumatic fibrosis that surrounds the nerve structures causing strangulation and inducing hypernociception, the use of surgical neurolysis is an appropriate alternative for patients with medically refractory neuropathic pain.

Hansen's disease (leprosy) remains an important health problem in Brazil, where 34,894 new cases were diagnosed in 2010, corresponding to 15.3% of the world's new cases detected in that year. The purpose of this study was to use home visits as a tool for surveillance of Hansen's disease in a hyperendemic area in Brazil. A total of 258 residences were visited with 719 individuals examined. Of these, 82 individuals had had a previous history of Hansen's disease, 209 were their household contacts and 428 lived in neighboring residences. Fifteen new Hansen's disease cases were confirmed, yielding a detection rate of 2.0% of people examined. There was no difference in the detection rate between household and neighbor contacts (pâ=â0.615). The two groups had the same background in relation to education (pâ=â0.510), household income (pâ=â0.582), and the number of people living in the residence (pâ=â0.188). Spatial analysis showed clustering of newly diagnosed cases and association with residential coordinates of previously diagnosed multibacillary cases. Active case finding is an important tool for Hansen's disease control in hyperendemic areas, enabling earlier diagnosis, treatment, decrease in disability from Hansen's disease and potentially less spread of Mycobacterium leprae.

OBJECTIVE: To determine the risk of preeclampsia in a population with respect to maternal and sister histories of chronic hypertension, preeclampsia and eclampsia. DESIGN: A case-control study of severe preeclampsia. SETTING: Maternity hospital in Natal, Brazil. PARTICIPANTS: A total of 412 subjects were enrolled, 148 cases and 264 controls. MAIN OUTCOME MEASURES: Personal and familial histories of hypertensive disorders. Odds ratio estimates of preeclampsia with respect to family history of hypertensive diseases. RESULTS: Women with a history of hypertensive disorders were more frequent in the case group (p = 0.001). Women whose mothers had a history of hypertension (p = 0.003), preeclampsia (p = 0.007) or eclampsia (p = 0.038) were at increased risk of severe preeclampsia. The risk of preeclampsia was greater when the woman had a sister with a history of hypertension (OR 2.60, 95% CI 1.60-4.21, p < 0.001), preeclampsia (OR 2.33, 95% CI 1.58-3.45, p < 0.001), or eclampsia (OR 2.57, 95% CI 1.28-5.16, p = 0.008). The risk of preeclampsia was also higher for women who had both a mother and sister with a history of hypertension (OR 3.65, 95% CI 1.65-8.09, p = 0.001). CONCLUSIONS: A family history of hypertensive disorders increased the risk of eclampsia and hemolysis elevated liver enzymes and low platelet (HELLP) syndrome in a Brazilian population.

Drug intoxication with disulfiram is a rare condition that may lead to severe and potentially fatal cardiovascular manifestations such as cardiogenic shock. We report the case of a female patient with refractory shock after deliberate self-poisoning with disulfiram. Clinical, biochemical and echocardiographic assessment, as well as invasive monitoring confirmed cardiogenic shock associated with this drug. The known mechanisms of action of disulfiram are discussed, and the major collateral effects, especially cardiovascular effects, are described. We underscore the importance of suspecting this diagnosis and of adopting prompt and the most adequate therapeutic approach in this context.
