IJMS, Vol. 17, Pages 1468: Melanoma Brain Metastasis: Mechanisms, Models, and Medicine

ag

The development of brain metastases in patients with advanced stage melanoma is common, but the molecular mechanisms responsible for their development are poorly understood. Melanoma brain metastases cause significant morbidity and mortality and confer a poor prognosis; traditional therapies including whole brain radiation, stereotactic radiotherapy, or chemotherapy yield only modest increases in overall survival (OS) for these patients. While recently approved therapies have significantly improved OS in melanoma patients, only a small number of studies have investigated their efficacy in patients with brain metastases. Preliminary data suggest that some responses have been observed in intracranial lesions, which has sparked new clinical trials designed to evaluate the efficacy in melanoma patients with brain metastases. Simultaneously, recent advances in our understanding of the mechanisms of melanoma cell dissemination to the brain have revealed novel and potentially therapeutic targets. In this review, we provide an overview of newly discovered mechanisms of melanoma spread to the brain, discuss preclinical models that are being used to further our understanding of this deadly disease and provide an update of the current clinical trials for melanoma patients with brain metastases.

: Background: Presently Anatomy is taught in a traditional way through lectures, small group teaching and demonstration. All these are teacher-controlled methods for teaching as per Medical Education Technology. So it was decided to introduce a learner-controlled method for teaching of Anatomy i.e. problem-based learning (PBL) with the following. Objectives:To compare the performance of the students undergoing PBL with the performance of the students taught in a traditional way To compare the perception of the students about PBL in comparison to Traditional way Materials and methods: 32 students who volunteered for the study were divided into two groups. The first group was taught cerebellum by PBL method and the second group was taught cerebrum by PBL method. Cross over method was then applied. Thereafter a theory examination was conducted. A feedback questionnaire was given to the students after the examination. Results: The average score of the students in the PBL group was more than that of the students in the lecture group in 60% questions. The score was same in 20% questions. The score was reverse in 20% of questions. PBL was appreciated and accepted by the students. It can be introduced partly in the existing curriculum. [ Yuvaraj b NJIRM 2016; 7(4): 92-97]

Background & Objectives: Problem-based learning (PBL) in medical education can be considered as the most significant innovation in educational tools in the past 35 years. This study was conducted to evaluate the students perceptions regarding PBL which will provide inputs to rectify the curriculum. Methods: The study was conducted in two years on two batches of 100 students each. Six PBL exercises on different topics were successively allotted to each batch of students in groups of 15-18. At the end of each year, the students were asked to fill a 21-item questionnaire on a 5-point Likert scale, regarding their perceptions for PBL. The mean/median scores of ≥3 was considered as positive attitude towards PBL Results: For 20 items related to PBL as T-L strategy and its effect on professional attitude, the mean/median scores was observed to be ≥3. Mean score of 2.04 and median score of 2 was found for the item that considered PBL as a waste of time; reinforcing the liking for PBL. Interpretation and Conclusion: PBL empowers students to engage in collaborative learning, improves inter-personal skills, enhances pre-existing knowledge and develops a professional attitude. It is recommended that it should be integrated in future Indian medical curriculum. [Manisha JNJIRM 2016; 7(4): 87-91]

Quantifying behavioural determinants relating to health professional reporting of medication errors: a cross-sectional survey using the Theoretical Domains Framework

Abstract

Purpose

The aims of this study were to quantify the behavioural determinants of health professional reporting of medication errors in the United Arab Emirates (UAE) and to explore any differences between respondents.

Methods

A cross-sectional survey of patient-facing doctors, nurses and pharmacists within three major hospitals of Abu Dhabi, the UAE. An online questionnaire was developed based on the Theoretical Domains Framework (TDF, a framework of behaviour change theories). Principal component analysis (PCA) was used to identify components and internal reliability determined. Ethical approval was obtained from a UK university and all hospital ethics committees.

Results

Two hundred and ninety-four responses were received. Questionnaire items clustered into six components of knowledge and skills, feedback and support, action and impact, motivation, effort and emotions. Respondents generally gave positive responses for knowledge and skills, feedback and support and action and impact components. Responses were more neutral for the motivation and effort components. In terms of emotions, the component with the most negative scores, there were significant differences in terms of years registered as health professional (those registered longest most positive, p = 0.002) and age (older most positive, p < 0.001) with no differences for gender and health profession.

Conclusion

Emotional-related issues are the dominant barrier to reporting and are common to all professions. There is a need to develop, test and implement an intervention to impact health professionals' emotions. Such an intervention should focus on evidence-based behaviour change techniques of reducing negative emotions, focusing on emotional consequences and providing social support.

Key messages

• This research used the Theoretical Domains Framework to quantify the behavioural determinants of health professional reporting of medication errors.

• Questionnaire items relating to emotions surrounding reporting generated the most negative responses with significant differences in terms of years registered as health professional (those registered longest most positive) and age (older most positive) with no differences for gender and health profession.

• Interventions based on behaviour change techniques mapped to emotions should be prioritised for development.

: Introduction: The concepts taught in pre-clinical sciences serve as a backbone to understand the clinical sciences. The system of teaching basic science subjects through didactic lectures followed in most of the medical colleges is more of a teacher centered. The medical educators are concerned about the learning outcomes of the traditional programs of teaching. Usually feedback on curriculum is obtained by subject experts from other universities. There is an unmet need to obtain the perceptions of graduates as they represent one of the important stakeholders of curriculum. Objective: To collect the interns perception about the content, need and application of biochemistry knowledge during their internship using a pre-designed and pre validated questionnaire. Materials and Methods: It was a cross sectional study done on interns who were asked to give feedback on biochemistry curriculum using the questionnaire. All the opinions were rated using 5- point Likert scale, ranging from strongly disagree to strongly agree. Results: 72.9% of interns were in favor of integrating basic science subjects with clinical sciences . Around 74.5 % (2/3rd) expressed that adopting interactive teaching strategies and problem based learning helped them in better understanding of the subject. Conclusion: The final goal of teaching in a medical sector includes attainment of knowledge, skills, attitudes and morals required to perform professional tasks safely and competently. In order to achieve this interactive, practical/case oriented and integrated teaching should be promoted. [Vanishree.B.JNJIRM 2016; 7(4): 82-86]

: Background and Objectives: Problem-based learning (PBL) is an innovative educational approach in which the students determine what they need to learn. The present study was done to review the pros and cons of PBL, with the aim to introduce reforms in the traditional teaching methodology.Methods: A total of 200 MBBS students participated in the study. Six PBL exercises were allotted to the students and after their completion, they were asked to fill the questionnaire regarding their perceptions about PBL on a 5-point Likert scale, as well as open ended questions to elicit two reasons each for liking and disliking PBL.Results: Regarding the students perceptions, the mean/median scores of all the items was found to be ≥ 3, indicating the positive inclination of students towards PBL. The major favourable factors of PBL were the opportunity of group discussion (16%) and better understanding (15.8%). The major drawbacks in PBL were that preparation required more time (20.5%), inadequate discussion (12.8%) and large group size(11.0%) Interpretation and Conclusion: Students generally favour PBL, as it enhances their ability to handle and solve real-life problems; however, few of the challenges are also accompanied with it which should be looked into to improvise it.

ANCA-negative eosinophilic granulomatosis with polyangitis (EGPA) manifesting as a large intracardiac thrombus and glomerulonephritis with angionecrosis

A 59-year-old woman with a history of bronchial asthma presented with a prolonged fever and eosinophilia. There was transient proteinuria and troponin level was elevated. Antineutrophil cytoplasmic antibody was negative and she did not fulfil criteria for eosinophilic granulomatosis with polyangitis (EGPA). Echocardiography showed a large apical mass in the left ventricle, but there was no systolic dysfunction, local asynergy or ventricular remodelling. On MRI, apical mass was compatible with a thrombus and endocardial region was diffusely damaged. Loeffler endocarditis-like cardiac manifestation led to meticulous examination, which found no aetiology for eosinophilia. Finally, renal biopsy revealed eosinophil infiltration and glomerular angionecrosis, confirming as EGPA. This case highlights the isolated large cardiac thrombus as a rare presenting sign for EGPA and underscores current complicated strategy to diagnose EGPA. Of note, this clinical challenge was mostly caused by inchoate comprehension of hypereosinophilia-related disorders.

Penetrating cardiac injury: sustaining health by building team resilience in growing civilian violence

Penetrating cardiac injury (PCI) is gradually increasing in developing countries owing to large-scale manufacturing of illegal country-made weapons. These injuries are associated with significant morbidity and mortality. Logistically it is difficult to have all organ-based specialists arrive together and attend every critically injured patient round-the-clock in developing countries. It is therefore important for doctors (physicians, surgeons and anaesthetists) to be trained for adequate management of critically injured patients following trauma. We report the approach towards 2 cases of haemodynamically unstable PCI managed by a team of trauma doctors. Time lag (duration between injury and arrival at hospital) and quick horizontal resuscitation are important considerations in the treatment. By not referring these patients to different hospitals the team actually reduced the time lag, and a quick life-saving surgery by trauma surgeons (trained in torso surgery) offered these almost dying patients a chance of survival.

On examination the patient had a shortened and externally rotated leg with absent peripheral pulses and cold peripheries concerning for vascular compromise. A plain radiograph demonstrated an anterior hip dislocation (AHD) with a greater trochanter (GT) fracture (figure 1). An urgent CT of the pelvis was performed to exclude the possibility of a femoral neck fracture (figure 2A, B). The hip was reduced under conscious sedation in the ED using the Allis method. The peripheral pulses returned. A further CT angiogram of the pelvis was performed which showed concentric reduction, an undisplaced GT fracture and a short segment dissection of the right external iliac artery which was managed conservatively as directed by the vascular team (figure 3A,...

Protective altruistic phlebotomy: hereditary haemochromatosis presenting as hepatocellular carcinoma in a non-cirrhotic 83-year-old man

Hereditary haemochromatosis is a multisystem disorder of iron metabolism. Hepatic manifestations include hepatomegaly, cirrhosis and hepatocellular carcinoma. Hepatocellular carcinoma is almost always preceded by cirrhosis. We present a case of an 83-year-old man without history of liver disease or iron overload who presented with abdominal pain. Workup revealed mildly elevated transaminases, ferritin of 3996 and a solitary liver tumour. Biopsy was consistent with hepatocellular carcinoma in a background of haemosiderosis without cirrhosis. He was diagnosed with hereditary haemochromatosis and hepatocellular carcinoma. He underwent a partial hepatectomy and was started on routine phlebotomy and surveillance imaging. He has improved and has not had signs of recurrence or new complications of haemochromatosis. We suggest a possible reason for his unique and late presentation.

Idiopathic subvalvular aortic aneurysm masquerading as acute coronary syndrome

Subvalvular aneurysms are the least common type of left ventricular (LV) aneurysms and can be fatal. Subaortic LV aneurysms are much rarer than submitral LV aneurysms and mostly reported in infancy. They can be congenital or acquired secondary to infections, cardiac surgery or trauma. Here, we report a unique presentation of a large, idiopathic subaortic aneurysm in an adult masquerading as an acute coronary syndrome. Diagnosis was made with the help of a CT aortography. Aneurysm was surgically resected with good results. This case highlights the clinical presentation and management of subaortic aneurysms, an important differential for congenital aortic malformations.

Toxins, Vol. 8, Pages 259: A Novel Zak Knockout Mouse with a Defective Ribotoxic Stress Response

Ricin activates the proinflammatory ribotoxic stress response through the mitogen activated protein 3 kinase (MAP3K) ZAK, resulting in activation of mitogen activated protein kinases (MAPKs) p38 and JNK1/2. We had a novel zak−/− mouse generated to study the role of ZAK signaling in vivo during ricin intoxication. To characterize this murine strain, we intoxicated zak−/− and zak+/+ bone marrow–derived murine macrophages with ricin, measured p38 and JNK1/2 activation by Western blot, and measured zak, c-jun, and cxcl-1 expression by qRT-PCR. To determine whether zak−/− mice differed from wild-type mice in their in vivo response to ricin, we performed oral ricin intoxication experiments with zak+/+ and zak−/− mice, using blinded histopathology scoring of duodenal tissue sections to determine differences in tissue damage. Unlike macrophages derived from zak+/+ mice, those derived from the novel zak−/− strain fail to activate p38 and JNK1/2 and have decreased c-jun and cxcl-1 expression following ricin intoxication. Furthermore, compared with zak+/+ mice, zak−/− mice have decreased duodenal damage following in vivo ricin challenge. zak−/− mice demonstrate a distinct ribotoxic stress–associated phenotype in response to ricin and therefore provide a new animal model for in vivo studies of ZAK signaling.

Psc-AFP from Psoralea corylifolia L. overexpressed in Pichia pastoris increases antimicrobial activity and enhances disease resistance of transgenic tobacco

Abstract

Psc-AFP, isolated from the seeds of Psoralea corylifolia L., is an antimicrobial protein with trypsin inhibitor activity. Its encoding gene was cloned by 3′- rapid amplification of cDNA ends (RACE) combined with Y-shaped adaptor-dependent extension (YADE) method. The gene Psc-AFP encodes a protein of 203 amino acids with a deduced signal peptide of 24 residues. The growth inhibition effect exerted by the heterologously expressed Psc-AFP in Pichia pastoris revealed that the recombinant Psc-AFP inhibited mycelium growth of Aspergillus niger, Rhizoctonia solani, and Alternaria brassicae and conidial germination of Alternaria alternata. The recombinant Psc-AFP also showed protease inhibitor activity manifested by the inhibition of trypsin. The transgenic tobacco bioassays confirmed that overexpressing Psc-AFP significantly enhanced the disease resistance of tobacco and that some of the transgenic lines were almost fully tolerant to Ralstonia solanacearum and A. alternata, whereas no apparent alteration in plant growth and development was observed. Collectively, these results indicate that the recombinant Psc-AFP is an active antimicrobial protein, with protease inhibitor activity that can be successfully produced in the yeast and tobacco and, therefore, maybe a potential antimicrobial candidate for practical use.

Expressions of ion co-transporter genes in salicylate-induced tinnitus and treatment effects of spirulina

Abstract

Background

Although the activity of tinnitus-related ion co-transporter are known, their mRNA expressions has seldom been reported. We aimed to investigate the mRNA expressions of tinnitus-related ion co-transporter genes, and treatment effects of Spirulina.

Methods

The mRNA expressions of K+–Cl co-transporter (KCC2) and Na-K-2Cl co-transporter 1 (NKCC1) genes in the cochlea and brain of mice were evaluated after tinnitus was induced by intraperitoneal injection of salicylate. The effects of spirulina water extract on these gene expressions were investigated.

Results

Compared to the control group, the tinnitus scores increased significantly, however, the salicylate-induced tinnitus could be reduced significantly by spirulina water extract. The tinnitus group had higher of borderline significance mRNA expression of KCC2 gene in the cochlear, significantly higher in the temporal lobes and in the frontal lobes. Meanwhile, compared to the tinnitus group, the spirulina group had significantly lower mRNA expression of KCC2 gene in the cochlear, temporal lobes, frontal lobes and parahippocampus/hippocampus. However, the NKCC1 mRNA expression was not significantly different between three groups in the cochlea and these brain areas.

Conclusion

Salicylate-induced tinnitus might be associated with increased mRNA expression of KCC2 gene, but not with mRNA expressions of NKCC1 gene in the cochlear and some tinnitus-related brain areas. Spirulina reduced the expression of KCC2 genes in salicylate-induced tinnitus.

Introduction- Staphylococcus aureus is one of the principal human pathogens that colonizes healthy individuals as well as causes severe infections in hospitalized patients. They have differential ability to spread and cause outbreaks in hospitals. The study was done to isolate S.aureus from various clinical samples and to know their antibiogram. Methodology- The study included a total of 312 Staphylococcus aureus strains isolated from various clinical specimens. The specimens received were processed further for identification by standard microbiological procedures like direct microscopic examination, culture and various standard identification methods. Antimicrobial susceptibility testing was done by Kirby-Bauer disc diffusion method on Mueller-Hinton agar as per CLSI guidelines. Result- A total of 312 isolates of S. aureus were obtained from various clinical samples. Male to female ratio was 1.6:1. Infection rate was more in age group 46-60 years. Staphylococcus aureus isolates were more commonly obtained from surgery department (38.78%) followed by orthopedics. All the strains were 100% sensitive to Vancomycin, Netilmicin, Linezolid and Teicoplanin. Higher resistance was noted against Penicillin(94.87%), Trimethoprim/Sulfamethoxazole(72.44%).Lower resistance was noted against Nitrofurantoin(13.33%). Conclusion- The determination of the anti-microbial susceptibility is also crucial for an optimal therapy, for epidemiological purposes and for infection control measures.

Background: Infection with HIV is the most potent risk factor for progression to active tuberculosis. Mycobacterium tuberculosis only have an approximately 10% lifetime risk of developing TB compared with 60% or more in persons infected with HIV and TB. Methodology: 100 HIV infected patients having symptoms of Tuberculosis were taken up for the study for a period of 18 months, meeting the criteria for the present study. Diagnosis of tuberculosis was based on clinical evaluation, sputum smear. Results: 100 HIV patients studied for period of 18 months . Majority of patients were in the age group of 30-41 years. 64% were males and 36% females. Labourers are commonly affected. Common presenting symptoms were fever(74%) cough (72%) and weight loss(62%). Associated clinical findings were pallor(63%), (12%) and oral thrush(14%). Pulmonary TB (69%) is the most common form. Conclusion: Majority of patients were in the age group of 30-41 years, 64% were males 36% females. Most common occupation affected was labourers. Fever (74%), cough (72%) and weight loss (62%), pallor (63%), lymphadenopathy (12%) and oral thrush (14%). Most common form of tuberculosis was pulmonary TB (69%). Among extra pulmonary tuberculosis pleural effusion (8%) was the most common presentation. [Siddaraya H NJIRM 2016; 7(4): 28-32]
