ABSTRACT

Background@#and Purpose While the clinical hallmarks of transient global amnesia (TGA) are well defined, its pathophysiological causes are poorly understood. Specifically, risk factors for recurrences are yet to be determined. @*Methods@#This retrospective study analyzed TGA cases diagnosed and treated within the TEMPiS telestroke network and a university stroke center in Germany. Demographic and clinical data were assessed and characteristics of TGA episodes were recorded, such as season of occurrence, trigger factors, duration, and concomitant symptoms. Follow-up of the potential recurrence of TGA was performed using a standardized questionnaire. @*Results@#Overall 109 patients were included (age 64±8 years [mean±SD], 59.6% female). The most common vascular risk factor was arterial hypertension (60.6%), and other concomitant conditions included migraine (11.9%), hypothyroidism (22.9%), and atrial fibrillation (4.6%). The most frequent concomitant clinical feature accompanying the TGA episode at admission was elevated blood pressure (48.6%). Nineteen patients experienced at least one recurrent TGA episode. Migraine and hypothyroidism were only observed in subjects with a single TGA episode without recurrence (migraine: 14.4% without recurrence vs. none in the recurrence group, p=0.02; hypothyroidism: 27.8% without recurrence vs. none in the recurrence group, p=0.009). In contrast, atrial fibrillation was more common in subjects with TGA recurrence (p<0.001). @*Conclusions@#Arterial hypertension is prevalent in TGA patients, with elevated blood pressure being the most-frequent concomitant condition. In our cohort, recurrence of TGA occurred in approximately one-fifth of patients. Concomitant conditions such as migraine, hypothyroidism, and atrial fibrillation occurred at different frequencies in the two groups.

ABSTRACT

PURPOSE@#Patients with multiple traumas are at high risk of developing respiratory complications, including pneumonia and acute respiratory distress syndrome. Many pulmonary complications are associated with systemic inflammation and pulmonary neutrophilic infiltration. Leukotriene-receptor antagonists are anti-inflammatory and anti-oxidant drugs subsiding airway inflammation. The present study investigates the effectiveness of montelukast in reducing pulmonary complications among trauma patients.@*METHODS@#This randomized, double-blind, placebo-control trial was conducted in patients with multiple blunt traumas and evidence of lung contusion detected via CT scan. We excluded patients if they met at least one of the following conditions: < 16 years old, history of cardiopulmonary diseases or positive history of montelukast-induced hypersensitivity reactions. Patients were allocated to the treatment (10 mg of montelukast) or placebo group using permuted block randomization method. The primary measured outcome was the volume of pulmonary contusion at the end of the trial. The secondary outcomes were intensive care unit and hospital length of stay, ventilation days, multi-organ failure, and the in-hospital mortality rate.@*RESULTS@#In total, 65 eligible patients (treatment = 31, placebo = 34) were included for the final analysis. The treatment group had more pulmonary contusion volume (mean (SD), mm3) at the right (68726.97 (93656.54) vs. 59730.27 (76551.74)) and the left side (67501.71 (91514.04) vs. 46502.21 (80604.21)), higher initial C-reactive peptide level (12.16 (10.58) vs. 10.85 (17.87)) compared to the placebo group, but the differences were not statistically significant (p > 0.05). At the end of the study, the mean (SD) of pulmonary contusion volume (mm3) (right side = 116748.74 (361705.12), left side = 64522.03 (117266.17)) of the treatment group were comparable to that of the placebo group (right side = 40051.26 (64081.56), left side = 25929.12 (47417.13), p = 0.228 and 0.082, respectively). Moreover, both groups have statistically similar hospital (mean (SD), days) (10.87 (9.83) vs. 13.05 (10.12)) and intensive care unit length of stays (mean (SD), days) (7.16 (8.15) vs. 7.82 (7.48)). Of note, the frequency of the in-hospital complications (treatment vs. control group) including acute respiratory distress syndrome (12.9% vs. 8.8%, p = 0.71), pneumonia (19.4% vs. 17.6%, p = 0.85), multi-organ failure (12.9% vs. 17.6%, p = 0.58) and the mortality rate (22.6% vs. 14.7%, p = 0.41) were comparable between the groups.@*CONCLUSION@#Administrating montelukast has no preventive or therapeutic effects on lung contusion or its complications.

ABSTRACT

Resumo Fundamento A doença arterial coronariana (DAC) devido à isquemia miocárdica causa perda permanente de tecido cardíaco. Objetivos Nosso objetivo foi demonstrar o possível dano ao miocárdio em nível molecular através dos mecanismos de autofagia e apoptose em pacientes submetidos à cirurgia de revascularização miocárdica. Métodos Um grupo recebeu uma solução de cardioplegia Custodiol e o outro grupo uma solução de cardioplegia sanguínea. Duas amostras miocárdicas foram coletadas de cada paciente durante a operação, imediatamente antes da parada cardíaca e após a liberação do pinçamento aórtico. Foram avaliadas as expressões de marcadores de autofagia e apoptose. O nível de significância estatística adotado foi de 5%. Resultados A expressão do gene BECLIN foi significativa nos tecidos miocárdicos do grupo CS (p=0,0078). Os níveis de expressão dos genes CASPASE 3, 8 e 9 foram significativamente menores no grupo CC. Os níveis pós-operatórios de TnT foram significativamente diferentes entre os grupos (p=0,0072). As expressões dos genes CASPASE 8 e CASPASE 9 foram semelhantes antes e depois do pinçamento aórtico (p=0,8552, p=0,8891). No grupo CC, os níveis de expressão gênica de CASPASE 3, CASPASE 8 e CASPASE 9 não foram significativamente diferentes em amostras de tecido coletadas após pinçamento aórtico (p=0,7354, p=0,0758, p=0,4128, respectivamente). Conclusões Com nossos achados, acreditamos que as soluções CC e CS não apresentam diferença significativa em termos de proteção miocárdica durante as operações de by-pass.


Abstract Background Coronary artery disease (CAD) due to myocardial ischemia causes permanent loss of heart tissue. Objectives We aimed to demonstrate the possible damage to the myocardium at the molecular level through the mechanisms of autophagy and apoptosis in coronary bypass surgery patients. Methods One group was administered a Custodiol cardioplegia solution, and the other group was administered a Blood cardioplegia solution. Two myocardial samples were collected from each patient during the operation, just before cardiac arrest and after the aortic cross-clamp was released. The expressions of autophagy and apoptosis markers were evaluated. The level of statistical significance adopted was 5%. Results The expression of the BECLIN gene was significant in the myocardial tissues in the BC group (p=0.0078). CASPASE 3, 8, and 9 gene expression levels were significantly lower in the CC group. Postoperative TnT levels were significantly different between the groups (p=0.0072). CASPASE 8 and CASPASE 9 gene expressions were similar before and after aortic cross-clamping (p=0.8552, p=0.8891). In the CC group, CASPASE 3, CASPASE 8, and CASPASE 9 gene expression levels were not found to be significantly different in tissue samples taken after aortic cross-clamping (p=0.7354, p=0.0758, p=0.4128, respectively). Conclusions With our findings, we believe that CC and BC solutions do not have a significant difference in terms of myocardial protection during bypass operations.

ABSTRACT

Resumo Os últimos meses de 2019 foram marcados pelo surgimento de uma nova pandemia, denominada "COVID-19". Desde então, essa infecção e suas complicações têm sido a prioridade de profissionais de saúde, com muitos sintomas atribuídos às suas apresentações precoces e tardias. Até o momento, outras doenças, mesmo em situações fatais, têm sido negligenciadas ou diagnosticadas incorretamente devido à atribuição dos sintomas do paciente à presença da infecção por COVID-19. Apresentamos aqui um caso de angiossarcoma cardíaco, em um menino que, cerca de 2 meses antes, havia sido infectado com COVID-19. Dado o histórico de infecção, a abordagem inicial foi o manejo da miopericardite pós-COVID-19. No entanto, o quadro do paciente piorou, exigindo reavaliação por multimodalidades com maior precisão. Por fim, o paciente foi diagnosticado com um tumor cardíaco. Este artigo procura enfatizar a importância da atenção a outras doenças e condições fatais na era COVID-19, com ênfase em evitar diagnósticos incorretos de outras doenças.


Abstract The final months of 2019 saw the emergence of a new pandemic termed "COVID-19". Since then, this infection and its complications have been the priority of healthcare providers, with many symptoms attributed to its early and late presentations. Thus far, other diseases, even fatal situations, have been overlooked or misdiagnosed due to the attribution of patient symptoms to the presence of COVID-19 infection. We herein present a case of cardiac angiosarcoma in a young boy who had previously become infected with COVID-19 about two months earlier. Given the history of infection, the initial approach was post-COVID-19 myopericarditis management. However, the patient's condition worsened, necessitating reevaluation via multimodalities with higher precision. Ultimately, the patient was diagnosed with a cardiac tumor. This article seeks to underscore the significance of taking heed of other diseases and fatal conditions during the COVID-19 pandemic with an emphasis on avoiding misdiagnosing other diseases.

ABSTRACT

Background@#Family function is a necessary factor that influences older people’s health. The Family APGAR has been widely used to study family functions. However, there has been no Persian version of this instrument to assess family function in older people. The aim of this study was to determine the psychometric properties of the Persian version of the Family APGAR Scale to evaluate the perception of family functions. @*Methods@#The “forward-backward” procedure was applied to translate the scale from English into Persian. The translated version was checked in terms of validity and reliability, with a sample of 281 older people selected from retirement centers. The factor structure of the scale was also tested using a confirmatory factor analysis. To test reliability, internal consistency and test–retest analyses were performed. @*Results@#The results of the confirmatory factor analysis indicated a good structural model. Criterion-related validity was strongly supported by the pattern of association between the APGAR Scale and the social support survey. Cronbach’s α of the scale was 0.88 and test–retest reliability ranged from 0.96 to 0.98, indicating a good range of reliability. @*Conclusion@#The findings of this study suggest that the Iranian version of the Family APGAR is a valid and reliable scale to evaluate family functions in health intervention programs.

ABSTRACT

PROPOSE@#In this study, we re-assessed the criteria defined by the radiological society of North America (RSNA) to determine novel radiological findings helping the physicians differentiating COVID-19 from pulmonary contusion.@*METHODS@#All trauma patients with blunt chest wall trauma and subsequent pulmonary contusion, COVID-19-related signs and symptoms before the trauma were enrolled in this retrospective study from February to May 2020. Included patients (Group P) were then classified into two groups based on polymerase chain reaction tests (Group Pa for positive patients and Pb for negative ones). Moreover, 44 patients from the pre-pandemic period (Group PP) were enrolled. They were matched to Group P regarding age, sex, and trauma-related scores. Two radiologists blindly reviewed the CT images of all enrolled patients according to criteria defined by the RSNA criteria. The radiological findings were compared between Group P and Group PP; statistically significant ones were re-evaluated between Group Pa and Group Pb thereafter. Finally, the sensitivity and specificity of each significant findings were calculated. The Chi-square test was used to compare the radiological findings between Group P and Group PP.@*RESULTS@#In the Group PP, 73.7% of all ground-glass opacities (GGOs) and 80% of all multiple bilateral GGOs were detected (p < 0.001 and p = 0.25, respectively). Single bilateral GGOs were only seen among the Group PP. The Chi-square tests showed that the prevalence of diffused GGOs, multiple unilateral GGOs, multiple consolidations, and multiple bilateral consolidations were significantly higher in the Group P (p = 0.001, 0.01, 0.003, and 0.003, respectively). However, GGOs with irregular borders and single consolidations were more significant among the Group PP (p = 0.01 and 0.003, respectively). Of note, reticular distortions and subpleural spares were exclusively detected in the Group PP.@*CONCLUSION@#We concluded that the criteria set by RSNA for the diagnosis of COVID-19 are not appropriate in trauma patients. The clinical signs and symptoms are not always useful either. The presence of multiple unilateral GGOs, diffused GGOs, and multiple bilateral consolidations favor COVID-19 with 88%, 97.62%, and 77.7% diagnostic accuracy.

ABSTRACT

Background@#Orofacial pain is defined as pain felt in the soft or hard tissues of the head, face, mouth, and neck. Chronic orofacial pain is often challenging to diagnose and difficult to treat. Due to the lack of available information about the prevalence and clinical form of orofacial pain, this study aimed to evaluate the characteristics of chronic orofacial pain in patients presenting at the Department of Oral Medicine of Shahid Beheshti Dental School between 2012 and 2022. @*Methods@#In this retrospective study, we evaluated the files of 121 patients at the Department of Oral and Maxillofacial Diseases of Shahid Beheshti Dental School, which were completed during 2012–2022. We extracted the required information from these files. @*Results@#In total, 121 files were included in the study (30 male, 91 female). The mean age of the patients was 43.68 ± 16.79 years. The most common diagnosis in patients with chronic orofacial pain was temporomandibular disorders (TMD) (55.3%). Among pain-related factors, psychological factors showed the highest frequency (30.5%).Opening and closing (43.8%) had the highest frequency among factors that increased pain, and the rest (6.6%) had the highest frequency among the factors that reduced pain. Most patients experienced unilateral pain over the masseter area. Most patients reported their pain intensity to be greater than 7 in the verbal analog scale (VAS). The most common symptom associated with pain was joint noise (37.1%). @*Conclusion@#A ten-year retrospective evaluation of patient files showed that more than half of the patients with chronic orofacial pain had TMD.

ABSTRACT

Abstract Despite decades of research, wound healing remains a significant public health problem. This study aimed to develop and evaluate a topical sodium alginate gel containing vancomycin (Van) loaded MMT NPs for wound healing applications. Van was loaded in MMT at different conditions (pHs of 6, 7 and temperatures of 40, 50 °C) (Van/MMT NPs). The optimum formulation (with the smallest particle size and a high value of zeta potential; 270.8 ± 77.35 nm and -35.96 ± 2.73, respectively) showed a high drug-loading capacity (entrapment efficacy of 96%) and a sustained release pattern of Van (95%) over 480 min. The optimum Van/MMT NPs were embedded into the sodium alginate (SA) gel (Van/MMT NPs/SA gel). The Van/ MMT NPs/SA gel showed a sustained and slow release pattern of Van (95%) over 50 h. FTIR tests revealed the electrostatic interaction between MMT and Van. The broth macrodilution tube method was used to determine the minimum inhibitory concentration (MIC) of Van, Van/ MMT NPs, and Van/MMT NPs/SA gel against Staphylococcus aureus. The results showed the promising antibacterial activity of Van/MMT NPs/SA gel, thus, this gel can be a promising formulation for the management of infected wounds

ABSTRACT

Abstract Introduction: Blood cardioplegia (BC) and Custodiol cardioplegia (CC) have been used for a long time in open heart surgery and are highly effective solutions. The most controversial issue among these two is whether there is any difference between them regarding myocardial damage after ischemia surgery. In this study, autophagy, apoptosis, and hypoxia markers were investigated and that way we evaluated the differences between BC and CC patients. Methods: A total of 30 patients were included in this study, using two different cardioplegic solutions. Three different whole blood samples of the patients were taken from a central vein (preoperatively, immediately postoperatively, and one day after surgery). Total ribonucleic acid was extracted from these samples. Quantitative real-time polymerase chain reaction was performed, and changes in gene expression were determined by the 2-∆∆Ct method of relative quantification. Results: In the CC group, Beclin gene expression level was found to be higher and this difference was statistically significant (P=0.0024). Similarly, cysteine-aspartic acid protease (caspase) 9 and hypoxia-inducible factor 1α messenger ribonucleic acid (mRNA) gene expression level increased and were significantly different in the CC group. In the BC group, Beclin and microtubule-associated protein light chain 3 expressions were higher in the samples taken one day after surgery. Caspases 3 and 8 gene expressions were significantly different in the BC group. Conclusion: As a result of the analysis performed between the two cardioplegia groups, it has been shown that CC harms the myocardium more than BC at the level of mRNA expression of related markers.

ABSTRACT

PURPOSE@#Traumatic hemorrhagic shock is a life-threatening event worldwide. Severe brain trauma accompanying femoral fractures can trigger inflammatory responses in the body and increase pre-inflammatory cytokines such as TNF-α, IL-1. The primary treatment in these cases is hydration with crystalloids, which has both benefits and complications. The purpose of this study was to investigate the effects of fluid therapy on the hemodynamics, coagulation profiles, and blood gases in such patients.@*METHODS@#In this cross-sectional study, patients were divided into two groups: femoral fracture group and non-femoral group. The hemodynamic status, coagulation profile, and blood gases of patients in both groups were evaluated upon arrival at the hospital and again 2 h later. Data were analyzed by t-test and ANOVA with repeated data and paired samples t-test.@*RESULTS@#A total of 681 trauma patients (605 men and 76 women) participated in this study, including 69 (86.3%) men and 11 (13.8%) women in femoral fracture group and 536 men (89.2%) and 65 women (10.8%) in non-femoral group. The laboratory parameters were evaluated in response to the equal amount of crystalloid fluid given upon arrival and 2 h later. Blood gases decreased in the fracture group despite fluid therapy (p < 0.003), and the coagulation profile worsened although the change was not statistically significant.@*CONCLUSION@#The treatment of multiple-trauma patients with femoral bone fractures should be more concerned with the need for the infusion of vasopressors such as norepinephrine. If there is evidence of clinical shock, excessive crystalloid infusion (limited to 1 L) should be avoided, and blood and blood products should be started as soon as possible.

ABSTRACT

Purpose@#Brucellosis as a worldwide zoonotic illness affect domestic animals and humans doesn’t have any vaccine for the prevention of infection in humans yet. The aim of this study was to evaluate the specific immune response following the administration of glycine nanoparticles as adjuvant and delivery system of a chimeric antigen contained trigger factor, Omp31, and Bp26 in murine model. @*Materials and Methods@#The chimeric antigen of Brucella was cloned and expressed in Escherichia coli (E. coli) BL21 (DE3). Purification and characterization of recombinant protein was conducted through Ni-NTA (nickel-nitrilotriacetic acid) agarose, SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis), and Western blot. Nanoparticle characteristics including morphology, particle size distribution, zeta potential, protein retention rate, and release rate were measured in vitro. Subsequently, nanoparticle contained antigen was administered to mice and blood sample was taken to measured the antibody level. @*Results@#The protein retention in the nanoparticles was successfully done and the nanoparticle characteristics were appropriate. The average size of glycine particles containing antigen was about 174 nm, and the absorption of protein was approximately 61.27% of the initial value, with a release rate of approximately 70% after 8 hours. Enzyme-linked immunosorbent assay result proved that the immunized sera of mice which were administered with nano-formula contains high levels of antibodies (immunoglobulin G) against recombinant chimeric antigen and also a high level of mucosal antibody (immunoglobulin A) in the oral group, which showed a desirable immunity against Brucella. @*Conclusion@#The results showed that chimeric antigen-loaded glycine nanoparticles can act as a vaccine candidate for inducing the cellular and humoral immune response against brucellosis.

ABSTRACT

BACKGROUND@#The dietary habits and lifestyle changes during the COVID-19 pandemic could affect the urinary risk factors in kidney stone formers. In this study, we investigated the effects of the COVID-19 pandemic on 24-h urine metabolites, as a surrogate for dietary intake, in patients with kidney stones, in Tehran, Iran.@*METHODS@#We evaluated the medical records of all patients with urolithiasis who visited in our stone prevention clinic from the beginning of COVID-19 in Iran to 1 year later (Feb 2020-Feb 2021) and compared it with the patients' medical records in the same period a year before COVID-19 (Feb 2019-Feb 2020).@*RESULTS@#The results of our stone prevention clinic showed a decrease in the number of visits during COVID-19. Twenty-four-hour urine urea, sodium, and potassium were significantly lower, and 24-h urine magnesium was significantly higher during COVID-19. Higher 24-h urine oxalate was only shown in patients with the first-time visit, whereas lower 24-h urine uric acid and citrate were only shown in patients with the follow-up visits.@*CONCLUSIONS@#COVID-19 pandemics may change some of the dietary habits of the patients, including lower salt, protein, and fruit and vegetable intake. Although economic issues, restricted access, or sanitation issues may be the reason for the undesirable dietary changes, the importance of a quality diet should be discussed with all patients, as possible. Since the number of patients visited in the stone clinic was lower during COVID-19, virtual visits could be an excellent alternative to motivate patients with kidney stones.

ABSTRACT

ABSTRACT Objective: To determine the level of clinical contamination in the clinic and laboratory of the prosthodontics department of Kerman Dental School. Material and Methods: Clinical surfaces of the dental units, the laboratory, and the professors' lounge of the prosthodontics department were randomly sampled. The sampled surfaces included the dental units' console, light switch, light handle, headrest, and air-water spray syringe in the clinic, plastering tables, buttons of the vibrator, polishing, and trimmer machines, acryl tables, handles of pressure pot and press machine, handpiece holders, work desks, and drawer handles in the laboratory, and desks, computer mouse and keyboard, telephone sets, and doorknob in the professor's lounge. The samples were examined for the type and growth of microorganisms. The data were entered into SPSS, where they were analyzed using the chi-square test at the 0.05 significance level. Results: Of all the samples taken, 89.9% showed microbial contamination. The most common type of contamination was fungus (34.8%) and the least common types were Enterococcus faecalis and Staphylococcus epidermidis (1.1%). The second and third most common types of bacteria in the samples were Staphylococcus aureus (18%) and Pseudomonas aeruginosa (12.4%), respectively. There was no significant difference between the frequencies of microbial contamination in the clinic, the laboratory, and the professors' lounge. Conclusion: Given the strong chance of cross-infection in the examined department and laboratory, it is necessary to enforce protocols for proper disinfection of surfaces before, between and after treatments.

ABSTRACT

ABSTRACT BACKGROUND: During the Helicobacter pylori (HP) infection, the infiltration of the leukocytes into stomach mucosa is directed by locally produced chemokines that play a decisive role in infection outcome. The CagA is the most potent virulence factor of HP, so that the infection with CagA + strains is associated with more severe complications than infection with CagA - HP. OBJECTIVE: The aim was to determine the expression of chemokines CXCL10, CCL17, CCL20 and CCL22, and their receptors by CagA + HP- and CagA - HP-derived crude extract (HP-CE)-stimulated peripheral blood mononuclear cells (PBMCs) from peptic ulcer (PU) patients. METHODS: The serum and the PBMCs were collected from 20 HP-infected PU patients, 20 HP-infected asymptomatic subjects (HIA) and 20 non-infected healthy subjects (NHS). The PBMCs were cultured in absence of stimulator or with 10 µg CagA + HP crude extract (CagA + CE), 10 µg CagA - HP crude extract (CagA - CE). Chemokines and receptors were measured by ELISA and real time-PCR respectively. RESULTS: In PU patients, the production of chemokines CXCL10, CCL17, CCL20 and CCL22, and the expression of chemokine receptors CXCR3, CCR4 and CCR6 by CagA + CE-induced PBMCs were significantly higher than non-stimulated and CagA - CE stimulated cultures. The CXCL10 production by CagA + CE stimulated PBMCs from HIA subjects was significantly higher than the equal cultures from PU and NHS groups. The CCL17 and the CCL20 production by non-stimulated, CagA + CE stimulated, and CagA - CE stimulated PBMCs from PU subjects were significantly higher than the equal cultures from NHS and HIA groups. The CCL22 production by non-stimulated, CagA + CE stimulated and CagA - CE stimulated PBMCs from NHS group were significantly higher than the equal cultures from HIA and PU groups. The CagA + CE stimulated PBMCs from HIA subjects expressed lower amounts of CCR6 in comparison with CagA + CE stimulated PBMCs from NHS and PU groups. The serum levels CXCL10 and CCL20 in PU and HIA groups were significantly higher than NHS subjects. NHS and HIA groups displayed higher serum levels of CCL22 in comparison with PU patients. CONCLUSION: Results indicated that the CagA status of bacterium influence the expression of chemokines and receptors by HP-CE stimulated PBMCs from PU patients.


RESUMO CONTEXTO: Durante a infecção por Helicobacter pylori (HP), a infiltração dos leucócitos na mucosa estomacal é dirigida por quimiocinas produzidas localmente que desempenham um papel decisivo no resultado da infecção. O CagA é o fator de virulência mais potente do HP, de modo que a infecção com cepas CagA + está associada a complicações mais graves do que a infecção com CagA - HP. OBJETIVO: O objetivo foi determinar a expressão das quimiocinas CXCL10, CCL17, CCL20 e CCL22, e seus receptores por CagA + HP- e CagA - extrato bruto (EB) derivado de HP (HP-EB) de células mononucleares do sangue periférico (CMSP) de pacientes com úlcera péptica (UP). MÉTODOS: O soro e as CMSP foram coletados de 20 pacientes com UP infectados pelo HP, 20 indivíduos assintomáticos infectados pelo HP (AI-HP) e 20 indivíduos saudáveis não infectados pelo HP (NI-HP). As CMSP foram cultivadas na ausência de estimulador ou com extrato bruto CagA + HP de 10 μg (CagA + EB), 10 μg CagA - extrato bruto HP (CagA - EB). Quimiocinas e receptores foram medidos por ELISA e PCR em tempo real, respectivamente. RESULTADOS: Em pacientes com UP a produção de quimiocinas CXCL10, CCL17, CCL20 e CCL22, e a expressão dos receptores de quimiocina CXCR3, CCR4 e CCR6 por CagA + CMSP induzidos pelo EB foram significativamente maiores do que as culturas não estimuladas e CagA - EB estimulados. A produção de CXCL10 por CagA + EB estimulou as CMSP de sujeitos AI-HP em proporção significativamente maior do que as culturas iguais dos grupos UP e NI-HP. A produção de CCL17 e CCL20 por grupos não estimulados, CagA + EB estimulado, e CagA - EB estimulou CMSP de sujeitos com UP e foram significativamente superiores às culturas iguais dos grupos NI-HP e AI-HP. A produção de CCL22 por grupos não estimulados, CagA + EB estimulado e CagA - EB estimulado pelo grupo NI-HP foram significativamente maiores do que as culturas iguais dos grupos AI-HP e PU. O CagA + EB estimulou as CMSP dos sujeitos do AI-HP, expressando menores quantidades de CCR6 em comparação com as CMSP estimuladas pelo CagA + EB de grupos NI-HP e UP. Os níveis sanguíneos de CXCL10 e CCL20 nos grupos UP e AI-HP foram significativamente superiores aos dos sujeitos do NI-HP. Os grupos NI-HP e AI-HP apresentaram níveis sanguíneos mais elevados de CCL22 em comparação com pacientes com UP. CONCLUSÃO: Os resultados indicaram que o estado CagA da bactéria influencia a expressão de quimiocinas e receptores por HP-EB estimulados CMSP de pacientes com UP.

ABSTRACT

Tuberculous mastitis is a granulomatous mastitis due to infection by mycobacterium tuberculosis. It’s a rare entity witch is often confused with breast carcinoma or pyogenic breast abscess because of its clinical and radiological aspect. The diagnosis is histological with identification of an epithelioid cell granulomas and necrosis. The treatment is based on anti-tuberculous therapy with a good clinical issue. Authors report a case of tubercular mastitis in a post-menopausal female diagnosed on adenectomy.

ABSTRACT

A cornual gestation is a rare form of ectopic gestations accounting for 2-4% of all tubal pregnancies with a high rate of mortality among to 2%-2.5%. A 25 years old woman prima gravida was presented to the obstetrical emergency department with 8 weeks amenorrhea, lower abdominal pain and vaginal bleeding. A clinical diagnosis of ectopic pregnancy was made and confirmed using Ultrasonography and serum beta-hCG test. On laparotomy exploration authors found a left cornual ruptured ectopic pregnancy then authors made a left cornual resection with left salpingectomy. There were no postoperative complications.

ABSTRACT

Abstract Introduction Tonsillectomy is one of the most common surgeries in the head and neck worldwide. This operation is carried out by different methods, the most frequent of which are the cold dissection and bipolar electrocautery techniques. Objective This study was conducted to assess and compare postoperative morbidity between cold dissection and bipolar electrocautery. Methods This prospective randomized clinical trial was performed on 534 patients who underwent tonsillectomy in Vali-e-Asr Hospital of Birjand, east of Iran from October, 2013 to October, 2015. The patients were systematically selected for cold dissection technique or bipolar electrocautery technique groups. Time of surgery, amount of intraoperative blood loss, postoperative hemorrhage, the intensity of local pain 4 and 24 hours after operation and nausea and/or vomiting were recorded and compared in the two groups to decide which technique is better. The data were analyzed in SPSS software (ver-22). The p-value less than 0.5 was considered significant. Results In this study, 51.7% of the cold dissection technique patients and 50.6% of the bipolar electrocautery technique participants were male. Compared to the cold dissection technique, the average intraoperative blood loss was significantly lower (p < 0.001) in the bipolar electrocautery technique group, while the intensity of local pain 4 and 24 hours after the operation was significantly higher (p < 0.001). Other variables showed no significant differences between the two groups. Conclusion Based on the findings of the present investigation, the bipolar electrocautery technique is suggested for tonsillectomy in children, while the cold dissection technique is preferred for adult patients.


Resumo Introdução A tonsilectomia é uma das cirurgias mais comuns de cabeça e pescoço em todo o mundo. Essa cirurgia é feita por diferentes métodos, os mais frequentes são a dissecção a frio e por eletrocauterização bipolar. Objetivo Este estudo foi feito para avaliar e comparar a morbidade pós-operatória na dissecção a frio e eletrocauterização bipolar. Método Este ensaio clínico prospectivo e randomizado foi feito em 534 pacientes submetidos a tonsilectomia no Vali-e-Asr Hospital de Birjand, no leste do Irã, de outubro de 2013 a outubro de 2015. Os pacientes foram selecionados de forma sistemática para o grupo submetido à técnica de dissecção a frio ou para o grupo com uso da técnica de eletrocauterização bipolar. Para a avaliação acerca da melhor técnica, os seguintes parâmetros foram registrados e comparados entre os dois grupos: tempo de cirurgia, quantidade de perda sanguínea intraoperatória, hemorragia pós-operatória, intensidade da dor local 4 e 24 horas após a cirurgia e ocorrência de náuseas e/ou vômitos. Os dados foram analisados no software SPSS (versão 22). O valor de p inferior a 0,5 foi considerado significante. Resultados Neste estudo, 51,7% dos participantes do grupo técnica de dissecção a frio e 50,6% do grupo técnica de eletrocauterização bipolar eram do sexo masculino. No grupo operado pela técnica de eletrocauterização bipolar a média de perda sanguínea intraoperatória foi significantemente menor (p < 0,001) em comparação à técnica de dissecção a frio, enquanto a intensidade da dor local 4 e 24 horas após a cirurgia foi significativamente maior (p < 0,001). As outras variáveis não apresentaram diferenças significantes entre os dois grupos. Conclusão Com base nos achados da presente investigação, para a tonsilectomia em crianças sugere-se o uso da técnica de eletrocauterização bipolar, enquanto a técnica de dissecção a frio é recomendada para pacientes adultos.

ABSTRACT

Background: Femoral 3-in-1 block is one of the most effective methods in cases of hip nailing surgery because of its ease, low cost, and fewer complications. This study aims to evaluate the effect of adding dexamethasone to peripheral nerve block solution.Methods: Forty-four ASA (I,II & III) patients aged between 50-80 years, scheduled for elective hip-nailing surgery who met inclusion and exclusion criteria were enrolled in this double blind randomized controlled trial. Patients were allocated into two groups randomly; at the end of the surgery, femoral 3-in-1 nerve block was performed with 40 ml of bupivacaine 0.25% solution with or without 8 mg dexamethasone. Pain score was measured for 24 hours.Results: We found no significant difference in pain intensity scores until hour 0.5 and the scores were below 1. Thereafter, the VAS scores increased, yet it remained below 3 in the first 12 postoperative hours. Morphine was administered during hours 12-24 in both groups, when VAS scores reached to about 4. The total amount of morphine consumption was a little lower in the case group, although the difference was not statistically significant. Conclusion: Adding dexamethasone to bupivacaine 0.25% for 3-in-1 block has no more benefit than bupivacaine 0.25% alone for acute postoperative pain management after elective hip nailing surgery

ABSTRACT

Primary breast lymphoma is a primary degeneration of the breast lymphoid tissue. Study aim to describe primary breast lymphoma; its clinical presentations, histological particularities and management methods. A 33 years-old patient with no medical history underwent a breast surgery. Its anatomo-pathological study, supplemented by immunohistochemistry, showed a primary breast lymphoma. The extension assessment was negative. The patient underwent chemotherapy with regression of the tumor. Breast lymphomas are rare conditions. Its clinical symptomatology is polymorphic and the imaging aspects are non-specific. It should be evoked in front of any breast tumor in order to avoid heavy breast surgery since the basic treatment is based on chemotherapy.

ABSTRACT

The malignant degeneration of mature ovarian teratomas is a rare phenomenon. Case reported two cases of squamous cell carcinoma developed on mature teratoma of the ovary in patients aged 54 and 41 who were seen for chronic pelvic pain. Their pelvic ultrasound showed cystic double-component images with sizes of 103 and 95 mm respectively suggestive of dermoid cysts, and the anatomopathological study of the pieces of adnexectomy confirmed the diagnosis. Although no clinical, radiological or biological signs are specific, ovarian dermal cyst degeneration is suspected in the presence of a large dermoid cyst in a postmenopausal or peri-menopausal woman. The careful anatomo-pathological study of the cyst in this case makes it possible to pose the diagnosis of certainty. A rare complication of the dermoid cyst, its prognosis is pejorative and depends mainly on its clinical stage at the time of diagnosis and the quality of its surgical treatment which must be as radical as possible.
