RESUMO

Complex metacarpophalangeal (MCP) joint dislocation is an uncommon entity, which occurs following a hyperextension injury. Closed reduction is not feasible due to entrapped volar plate and/or coexisting fractures. Various approaches and techniques have been proposed for treatment of complex MCP dislocation; however, controversies exist over which one is superior. This study describes a right-handed 14-year-old boy who fell on the outstretched hand and sustained a dorsal dislocation of the left index MCP joint. The dislocation was complicated by an epiphyseal metacarpal head fracture with dorsal-ulnar displacement of the osteochondral fragment. The patient underwent open reduction through the dorsal approach, and the metacarpal head was fixed via the two-screw technique. The patient resumed left-hand function after six weeks. At the two-year follow-up, the range of motion and grip strength were normal, the patient was pain-free, and no sign of growth disturbance or joint stiffness was detected. Dorsal surgical approach with screw fixation is a feasible technique for the treatment of complex MCP dislocation, especially when it is complicated by a large epiphyseal head fracture.

RESUMO

BACKGROUND: Temporal resolution is essential to speech acoustic perception. However, it may alter in individuals with auditory disorders, impairing the development of spoken and written language. The envelope of speech signals contains amplitude modulation (AM) that has critical information. Any problem reducing the listener's sensitivity to these amplitude variations (auditory temporal acuity) is likely to cause speech comprehension problems. The modulation detection threshold (MDT) test is a measure for evaluating temporal resolution. However, this test cannot be used for patients with poor cooperation; therefore, objective evaluation of MDT is essential. PURPOSE: The main aim of this study is to find the association between the auditory steady-state response (ASSR) and psychoacoustic measurement of MDT at different intensity levels and to assess the amplitude and phase of ASSR as a function of modulation depth. DESIGN: This was a correlational research. STUDY SAMPLE: Eighteen individuals (nine males and nine females) with normal hearing sensitivity, aged between 18 and 23 years, participated in this study. DATA COLLECTION AND ANALYSIS: ASSR was recorded at fixed AM rates and variable AM depths for carrier frequencies of 1,000 and 2,000 Hz with varying intensities. The least AM depth, efficient to evoke an ASSR response, was interpreted as the physiological detection threshold of AM. The ASSR amplitude and phase, as a function of AM depth, were also evaluated at an intensity level of 60 dB hearing level (HL) with modulation rates of 40 and 100 Hz. Moreover, the Natus instrument (Biologic Systems) was used for the electrophysiological measurements. An AC40 clinical audiometer (Intra-acoustic, Denmark) was also used for the psychoacoustic measurement of MDT in a similar setting to ASSR, using the two-alternative forced choice method. Pearson's correlation test and linear regression model and paired t-test were used for statistical analyses. RESULTS: A significant positive correlation was found between psychoacoustic and electrophysiological measurements at a carrier frequency of 1000 Hz, with a modulation rate of 40 Hz at intensity levels of 60 dB HL (r = 0.63, p = 0.004), 50 dB HL (r = 0.52, p = 0.02). A significant positive correlation was also found at a carrier frequency of 2000 Hz, with a modulation rate of 47 Hz at 60 dB HL (r = 0.55, p = 0.01) and 50 dB HL (r = 0.67, p = 0.002) and a modulation rate of 97 Hz at 60 dB HL (r = 0.65, p = 0.003). Moreover, a significant association was found between the modulation depth and ASSR amplitude and phase increment at carrier frequencies of 1,000 and 2000 Hz, with modulation rates of 40 and 100 Hz. CONCLUSION: There was a significant correlation between ASSR and behavioral measurement of MDT, even at low intensities with low modulation rates of 40 and 47 Hz. The ASSR amplitude and phase increment was a function of modulation depth increase. The findings of this study can be used as a basis for evaluating the relationship between two approaches in the clinical population.

RESUMO

Backgrounds and aims: Clinical studies demonstrated that the efficacy of Coenzyme Q10 (CoQ10) as an adjuvant therapeutic agent in several neurological diseases such as Parkinson disease (PD), Huntington disease (HD), and migraine. The purpose of this study is to investigate oxidative stress effects, antioxidant enzymes activity, neuroinflammatory markers levels, and neurological outcome in acute ischemic stroke (AIS) patients following administration of CoQ10 (300 mg/day). Methods: Patients with AIS (n = 60) were randomly assigned to a placebo group (wheat starch, n = 30) or CoQ10-supplemented group (300 mg/day, n = 30). The intervention was administered for 4 weeks. Serum CoQ10 concentration, malondialdehyde (MDA), superoxide dismutase (SOD) activity, glial fibrillary acidic protein (GFAP) levels as primary outcomes and National Institute of Health Stroke Scale (NIHSS), Modified Ranking Scale (MRS), and Mini-Mental State Examination (MMSE) as secondary outcome were measured at the both beginning and end of the study. Results: Forty-four subjects with AIS completed the intervention study. A significant increase in CoQ10 level was observed in the supplement-treated group compared with placebo group (mean difference = 26.05 ± 26.63 ng/ml, 14.12 ± 14.69 ng/ml, respectively; P = 0.01), moreover CoQ10 supplementation improved NIHSS and MMSE scores significantly (P = 0.05, P = 0.03 respectively). but there were no statistically significant differences in MRS score, MDA, SOD, and GFAP levels between the two groups. Conclusions: CoQ10 probably due to low dose and short duration of supplementation, no favorable effects on MDA level, SOD activity and GFAP level.

RESUMO

INTRODUCTION: Different scoring systems based on clinical and laboratory findings are designed for prediction of short-term mortality of patients with severe sepsis and septic shock. This study aimed to compare the screening performance characteristics of PIRO, SOFA and MEDS Scores in predicting one-month mortality of sepsis patients. METHODS: This diagnostic accuracy study was performed on septic shock and severe sepsis patients referring to emergency department of Loghmane Hakim Hospital, Tehran, Iran, from 2017 to 2018. The performance of MEDS, SOFA, and PIRO models in predicting 30-day mortality of patients was evaluated using discrimination and calibration indices. RESULTS: 200 patients with the mean age of 71.03±15.59 years were studied (61% male). During the 30 days, 66 patients died (mortality rate=33%). The area under the ROC curve of PIRO, MEDS, and SOFA scores were 0.83 (95% CI=0.78-0.89), 0.94 (95% CI=0.91-0.97) and 0.87 (95% CI=0.81-0.92), respectively. Based on Brier, BrierScaled and Nagelkerke's R2 of the models, the best performance in predicting one-month mortality belonged to MEDS score. C-statistic showed that MEDS score had the highest value in the differentiation between the survived and non-survived cases. CONCLUSION: This study showed that MEDS score performs better than PIRO and SOFA scores in predicting one-month mortality of patients with severe sepsis and septic shock.

RESUMO

Disruption of prooxidant-antioxidant balance may lead to oxidative stress which is known as a mechanism contributing to ischemic stroke. Coenzyme Q10 (CoQ10) is an endogenous antioxidant that could be effective in preventing oxidative stress. However, the contribution of serum levels of CoQ10 in clinical neurological outcomes following ischemic stroke has not been clearly established. This study aims at measuring serum concentration of CoQ10 along with major indicators of antioxidant and oxidant among patients within 24 h after onset of the stroke symptoms, and investigating their relation with the clinical status of patients. Serum levels of CoQ10, superoxide dismutase (SOD), and malondialdehyde (MDA) were measured in 76 patients and 34 healthy individuals. Severity of the neurological deficit, functional disability, and cognitive status in ischemic subjects were respectively studied with the National Institutes of Health stroke scale (NIHSS), modified Rankin Scale (MRS), and Mini-Mental State Examination (MMSE). Stroke patients had significantly lower serum level of CoQ10 and SOD as compared to controls (27.34 ± 35.40 ng/ml, 18.58 ± 0.76 µ/ml, respectively; p < 0.05), whereas the serum MDA level was significantly higher (38.02 ± 2.61 µm, p < 0.05). A significant negative correlation was detected between the serum CoQ10 level and scores of NIHSS and MRS. A similar association was discerned between the SOD level and the neurological deficit score. The serum MDA level was also found to be strongly correlated with all three neurological scales. These findings suggest that the serum level of CoQ10 like other antioxidant and oxidant markers can significantly change early after ischemic stroke and they are substantially associated with clinical neurological outcomes.

RESUMO

INTRODUCTION: Using pan or selective computed tomography (CT) scan in management of multiple trauma patient is a matter of debate. Therefore, the present study was designed aiming to compare the findings of pan and selective CT scans in management of multiple trauma patients. METHOD: This is a prospective cross-sectional study, on patients presented to the emergency department (ED) of Shohadaye Haftome Tir Hospital, Tehran, Iran, following blunt multiple trauma over a 1-year period, from March 2014 to March 2015. Findings regarding presence or absence of injury in head, face, neck, chest, abdomen and hip were compared between patients that underwent pan and selective CT using SPSS 21. RESULTS: 443 patients with the mean age of 34.54 ± 17.88 years were evaluated (78% male). 248 (56%) patients underwent selective CT scan and 195 (44%) underwent pan CT scan. The 2 groups were similar regarding vital signs and mean age. Mean hospital length of stay was 21.05 ± 24.64 days for selective CT scan group and 18.18 ± 22.75 days for the other one (p = 0.209). A significant difference was only seen regarding findings of chest injury between the 2 groups (p < 0.001). In other cases a proper overlap was seen between findings of the 2 groups. CONCLUSION: Based on the results of the present study, it seems that doing selective CT scan yields results similar to pan CT in detection of head and face, neck and abdomen and hip injuries in multiple trauma patients. However, using pan CT in these patients led to 16% increase in detection and diagnosis of traumatic intra-thoracic injuries.

RESUMO

INTRODUCTION: More than 50 scoring systems have been published for classification of trauma patients in the field, emergency room, and intensive care settings, so far. The present study aimed to compare the ability of trauma injury severity score (TRISS) and acute physiology and chronic health evaluation (APACHE) III in predicting mortality of intensive care unit (ICU) admitted trauma patients. METHODS: This prospective cross-sectional study included ICU admitted multiple trauma patients of Imam Hossein and Hafte-Tir Hospitals, Tehran, Iran, during 2011 and 2012. Demographic data, vital signs, mechanism of injury and required variables for calculating APACHE III score and TRISS were recorded. The accuracy of the two models in predicting mortality of trauma patients was compared using area under the ROC curve. RESULTS: 152 multiple trauma patients with mean age of 37.09 ± 14.60 years were studied (78.94% male). 48 (31.57%) cases died. For both APACHE III and TRISS, predicted death rates significantly correlated with observed death rates (p < 0.0001). The mean age of dead patients was 37.21 ± 14.07 years compared to 37.03±14.96 years for those who survived (p = 0.4). The area under ROC curve was 0.806 (95% CI: 0.663-0.908) for TRISS and 0.797 (95% CI: 0.652-0.901) for APACHE III (p = 0.2). CONCLUSION: Based on the results of this study, both TRISS and APACHE models have the same accuracy in predicting mortality of ICU admitted trauma patients. Therefore, it seems that TRISS model would be more applicable in this regard because of its easier calculation, consideration of trauma characteristics, and independency of patient care quality.

RESUMO

This is a report of a 24-year-old woman who presented to the emergency department (ED) at Imam Hossein Hospital in Tehran, Iran with a one-week history of headache and agitation following her father's death. Before presenting to our ED, a diagnosis of conversion reaction was suggested by three physicians in different outpatient clinics. Cerebral venous thrombosis (CVT) was confirmed in this case on the basis of brain magnetic resonance imaging (MRI) and magnetic resonance venography (MRV). In this report, current knowledge regarding cerebral venous thrombosis and its related clinical features are discussed.

RESUMO

According to previous animal studies, aluminium phosphides (AlPs) may induce oxidative stress leading to generation of free radicals and alteration in antioxidant defense system. This study was conducted to evaluate the existence and degree of oxidative stress in patients with acute AlP ingestion. A total of 44 acute AlP ingested patients as well as 44 age- and sex-matched controls were included. All patients had acute poisoning symptoms with AlP at the time of presentation and had blood samples analyzed for lipid peroxidation, total antioxidant capacity and total thiol. Our findings showed that there is a significant increase in lipid peroxidation in AlP ingested group along with a reduction in total antioxidant capacity and total thiols groups. These clinical data confirm previous experimental models that showed AlP exposure might significantly augment lipoperoxidative damage with simultaneous alterations in the antioxidant defense system. Hence, our findings might justify use of antioxidants in treatment of acute AlP poisoning which needs to be clarified by additional clinical trials.
