Organizing a Medical Conference: Management Perspective

It is an incredibly formidable as well as meritorious task to plan and implement a successful medical conference. Organizing a medical conference requires a tremendous amount of planning, preparation, lots of pre conference works, and working on logistics to achieve its vision and goal. The two most important aspects for the success of any event is planning and implementation which requires a plenty of brainstorming sessions and meetings, and for medical practitioners and academicians, we are confronted with the dual role of organizing the conference as well as regular work juggling. Despite the fact that medical conferences play a major role in ongoing professional development, academic growth, and networking, there is little guidance in form of literature for those who want to hold a  conference inbound or outbound. This paper seeks to incorporate all the possible steps, plans and procedures in order to organize a successful conference. 

Epidemiology and Pattern of Traumatic Brain Injuries at Annapurna Neurological Institute & Allied Sciences, Kathmandu, Nepal

BACKGROUND

Traumatic brain injury (TBI) constitutes a major health and socioeconomic problem worldwide. It represents the greatest contribution to death and disability among all trauma-related injuries globally. TBIs are a leading cause of death and disability in Nepal, despite improvements in safety regulations and implementation of strict drunk driving laws. We describe the epidemiology of patients with TBI following admission to our hospital. We discuss the implementation of specific strategies to reduce its incidence.

METHODS

We conducted a retrospective cross-sectional study of patients presenting to Annapurna Neurological Institute & Allied Sciences (ANIAS), Kathmandu, with a TBI between September 2018 to September 2019.

RESULTS

One-hundred and sixty-seven patients presented with a TBI. The most common age groups were younger than 15 years old and 15-25 years old, and the majority were male (73%). The commonest cause of TBI was road traffic accidents (RTA) (59%). Drivers riding motorcycles were the predominant mechanism of RTA (38%). Helmet use was seen in 57% of patients riding 2-wheelers. Alcohol consumption was reported in 22% of all patients. Skull fractures were the most common diagnosis. Most patients were managed conservatively (84%).

CONCLUSIONS

TBI should be recognized as an important public health problem in Nepal. TBI is responsible for a considerable number of neurosurgical admissions to ANIAS. Our study showed patients most vulnerable to TBI are males younger than 25 years old. The implementation of stricter traffic rules and regulations, helmet law enforcement, and public education programs may be helpful in decreasing the number of TBI.

Cytotoxic effect of selected wild orchids on two different human cancer cell lines

Majority of the orchid species are used in the traditional medicines for the treatment of several diseases. They are the sources of polysaccharides, phenanthrenes, bibenzyl derivatives, revesteral, stilbenoids and polyphenol compounds. This study explored the cytotoxic activity of seven wild orchid species and identification of medicinally active compounds. The extracts of orchid species were screened for cytotoxic effect on the human cervical cancer cells (HeLa) and human glioblastoma cells (U251) using an MTT assay. The medicinally active compounds of high cytotoxic extracts were identified by GC-MS resulting in many stilbenoids and phenolic derivatives. The extract of Dendrobium transparens (DTs) and Vanda cristata (VCw) showed high cytotoxic effect towards the HeLa and U251 cell lines (IC50 of DTs: 382.14 μg/ml and 75.84 μg/ml respectively and IC50 of VCw: 317.23 μg/ml and 163.66 μg/ml respectively). This study concludes that they could be used as cancer therapeutics.

Extradural Hydatid Cyst of the Lumbo-Sacral Spine

Primary spinal hydatid cyst is a rare and uncommon entity but a significant manifestation of hydatid disease. Here, we report a case of primary extramural hydatid cyst of the sacral region causing cord compression. Pre-operative differential diagnosis was that of Tarlov cyst owing to the radiological appearance and location of the cyst. The diagnosis of hydatid cyst was established intra-operatively which was later confirmed by histopathology report. Hydatidcyst may not fall under differential diagnosis of extramural lesions of the spine due to its rarity but should be kept under high suspicion in endemic countries.

A Case Report of Lhermitte-Duclos Disease in a 10-Month-Old Child Presenting with Hydrocephalus

Lhermitte–Duclos Disease is a rare entity characterized by diffuse or focal enlargement of cerebellar folia. Clinical manifestations are usually related to a mass effect and secondary obstructive hydrocephalus. Increased intracranial pressure symptoms and cerebellar symptoms are the most frequent patient complaints. We present a 10-month-old male child with his mother who presented to the outpatient department with complaints of enlargement of size of head since the last one week. Magnetic Resonance Imaging scan revealed the features of Lhermitte–Duclos Disease involving the right cerebellar hemisphere with marked post contrast gyral enhancement. He underwent endoscopic third ventriculostomy. Lhermitte–Duclos Disease is very rare in early childhood and should be considered in the differential diagnosis of posterior fossa lesions.

Organizing a Health Camp: Management Perspective

Health camps or outreach clinics are the effective strategies adopted by both government and non-government organizations, associations, and societies with various interests and scope. A well-organized health camp with a concentration on the various principles of planning, coordination, collaboration, tools, and techniques will not only make the health camp successful but also aids in improving the health status of the unreached community who are often deprived of basic to advance health care facility due to different circumstances.

Hypophonia as only presenting symptom in myasthenia gravis - a diagnostic dilemma in poor countries: a case report

INTRODUCTION

The autoimmune disease myasthenia gravis can mimic a variety of neurological disorders leading to a delay in diagnosis and treatment. In the older population, due to confusion with signs of the ageing process or comorbidities due to ageing, there are many underdiagnosed or misdiagnosed cases of myasthenia gravis. A majority of myasthenia gravis symptoms appear as ocular or motor symptoms and there are very few cases of bulbar symptoms. We present a case of myasthenia gravis with only hypophonia as a clinical feature.

CASE PRESENTATION

We present a case of a 51-year-old Madheshi woman whose only complaint was sudden onset of hypophonia which later showed a fluctuating nature throughout the daytime. There was only reduced pitch in her voice with no nasal tone or dysarthria (so-called dysphonia), which created a diagnostic dilemma. Later, a neurological examination and other relevant investigations suggested myasthenia gravis.

CONCLUSIONS

Sudden onset and focal neurological deficit can raise the diagnostic dilemma of myasthenia gravis. Relevant laboratory tests and clinical examinations are important to diagnose this disease properly. In resources-deprived nations like Nepal, where several investigations are expensive and access to them is difficult, it becomes very difficult to achieve a solid diagnosis for rare presentations of diseases.

Abstract WP570: Associations Between Stroke Symptoms and Cognition in Nepal

Introduction: Low and middle income countries have the largest burden of stroke, accounting for more than 85% of stroke deaths globally. As many low- and middle-income countries, including Nepal, transition from communicable to non-communicable diseases (NCDs), the impact of stroke on cognition becomes increasingly important.

Methods: Data on cardiovascular risk factors and cognition were collected as part of the Dhulikhel Heart Study, a longitudinal study to evaluate risk factors for heart disease and stroke in Dhulikhel, a community outside of Kathmandu, Nepal. In Phase 1 of the baseline exam, 252 randomly-selected adults age 50 and older completed the Mini-Mental Exam (MMSE) and Digit Spans ( DST) forward and backward as part of a home interview. Mild stroke symptoms were collected by self-report the Questionnaire for Verifying Stroke-Free Status (QVSFS). Multiple linear regression evaluated associations between stroke symptoms and cognition adjusted for demographics (age, sex, education, religion, and ethnicity) and CVD risk factors (smoking, exercise, BMI, blood pressure, hypertension, and diabetes).

Results: Mean age of study participants was 62.4 years (SD 9.2) and 57.5% were women. The mean MMSE score (weighted for illiteracy) was 18.7 (SD 6.4) and 19% reported to have had at least one of five stroke symptoms (sudden one-sided numbness or weakness, sudden vision-loss, inability to express oneself or inability to understand). An increased risk of lower memory score was found with report of a previous episode of numbness (DST backward: B=-1.17, SE=0.34, p=0.001). Borderline associations (.05 < p<.10) were found between any stroke symptoms and Digit Span forward, numbness and MMSE, and numbness and DST forward. When adjusted for demographic and cardiovascular risk factors, significant associations were found between having experienced any stroke symptom and Digit Span backward (B=-1.46, SE=0.66, p=.03) as well as numbness (B=-1.75, SE=0.72, p=0.02).

Conclusions: Associations between previous stroke symptoms and reduced cognition emphasize the need to screen and treat persons with undiagnosed stroke or TIAs in low-resource settings. A reduction in modifiable vascular risk factors is also needed to reduce CVD and associated dementia.

Technical Notes and Result of Stereotactic Evacuation of Hematoma in Spontaneous Supratentorial Intracerebral Hematoma

Primary intracerebral hematoma constitutes about 10-15% of all strokes and is associated with high mortality and severe disability. Surgical treatment of intracerebral hemorrhage is quite controversial. It is believed that minimal invasive stereotactic surgery may reduce hematoma volume and decrease secondary neurotoxicity. The technical note of stereotactic surgery has been illustrated. A retrospective study from March 2016 to March 2018 has been conducted and all patients who underwent stereotactic evacuation of hematoma were included in this study. Baseline characteristics of patients and outcome in terms of Glasgow Coma Scale (GCS) and Modified Rankin Scale (mRS) have been shown. We have found significant improvement in GCS postoperatively, however mRS did not improve immediately but was significantly better in three months follow up period.

Histopathological analysis of central nervous system tumor; an observational study

Background:  Though the central nervous system tumor comprises ~2% of all the tumors, an overall increase has been observed especially in less developed countries. This increase in the incidence may be due to exposure of population to various risk factors or improved diagnosis with advancement in the ancillary studies. This study aims to provide a single centre histopathological spectrum of this type of tumor.Materials and Methods: A retrospective cross sectional study on a series of cases was performed in the Department of Pathology, Annapurna Neurological Institute & Allied Science , Maitighar , Kathmandu, Nepal from April 2013 to Jan 2016. Data were analyzed using SPSS version 21.0.Results: A total of 221 brain and CNS tumors (125 females and 96 males) were studied. The mean age at diagnosis was 43.77 years. The most common tumor was meningioma(67 cases, 30.3%), followed by astrocytic tumor (57 cases, 25.7%) and pituitary adenoma(30 cases,13.6%). The frequency of WHO grade I, II,III and IV tumor were 94 cases (55%), 34 cases (19.9%),10 cases (5.8%), and 33 cases (19.3%) respectively. The astrocytic tumor was most frequent tumor in children (7/20 caes, 37 %).Conclusion: This study showed the most common CNS tumor to be meningioma followed by astrocytic tumors and pituitary adenoma. The spectrum of CNS tumor in children showed divergent histologic pattern according to the age. In age group 0-10 years embryonal tumors were common whereas ages group of 12-years showed propensity towards astrocytoma as in adults.  

Initial experience with aneurysm coiling in Nepal

The aim of this study is to show the result of aneurysm coiling despite the difficulty in initiating neurointervention in Nepal. It is a retrospective study where only aneurysm that has undergone coiling are taken from 2017 to 2018.A total of eleven patients (male: female = 1: 10) with aneurysm were treated with Endovascular therapy. 9 cases were ruptured aneurysm while 3 were unruptured. 5 aneurysm were located in anterior circulation while 6 were located in posterior circulation. Out of eleven cases 4 were treated by simple coiling technique, while 2 underwent balloon assisted coiling, 3 stent assisted coiling, 1 pConus assisted coiling and 1 simple coiling and stent assisted coiling. Statistical analysis showed significant correlation between fisher grading scale with mRS score (P=0.013) suggesting lower fisher grade, and improved outcome similar to the result of prospective one year follow up of Barrow Ruptured Aneurysm Trial ( BRAT) study. With limited resources aneurysm coiling was performed at ANIAS with similar results to literature.Nepal Journal of Neuroscience, Volume 15, Number 2, 2018, page: 30-35

Deep Brain Stimulation in Parkinsons Disease in Nepal

Background Parkinsons disease is a central nervous system degenerative disorder affecting motor system and characterized by progressive tremor, rigidity, gait abnormalities. Surgical treatment of Parkinsons disease is based on the changes in the basal gangliothalamocortical circuits which is altered in Parkinsons disease. Currently pallidotomy and Deep Brain Stimulation are available modes of surgical treatment of Parkinsons disease. Objective To know efficacy of deep brain stimulation in Parkinsons Disease in Nepal. Method All patients of idiopathic Parkinsons disease who underwent Deep Brain Stimulation in Annapurna Neurological Institute and Allied sciences since 2014 were included. The standard functional coordinates for Subthalamic nucleus and Globus pallidus internus was used. We used Zamarano-Dujovny (ZD) Fisher Frame with its software. Patients' Unified Parkinsons disease rating score, Modified Hoehn and Yahr Staging and Schwab and England Activities of daily living Scale were evaluated preoperativelyv as well as postoperatively. Result Ten patients underwent Deep Brain Stimulation. The male is to female ratio was 2:1. The mean age was 55.4±8.9 years and duration of illness was 5.5±2 years. There was a significant improvement in the scores for the main motor manifestations of the disease between the preoperative off-dopa and postoperative off-dopa/on-stim conditions. There was a significant improvement in Schwab and England Activities of daily living scale scores in the off-dopa condition between the preoperative score and the postoperative M6 score. Conclusion Our result of Deep Brain Stimulation is quite promising. However, it is very expensive and requires frequent follow-up for neuromodulation.

Cerebral venous thrombosis secondary to hyperthyroidism: A case report

Cerebral Venous Thrombosis (CVT) is a rare form of Stroke characterized by thrombus formation in the cerebral veins. CVT is a result of various reasons among which the hyperthyroidism is not so frequently encountered. This is probably the first case report published from Nepal. The aim of this case report is to give the message that persistent severe headache in patient with hyperthyroidism can be the red flag and needs to be investigated further. We present a case of a 35 years old female who presented with complaints of severe headache and persistent in nature associated with vomiting since 5 days. She was a diagnosed subacute thryroiditis and under medicine from 1 month before presenting to us. Her Magnetic Resonance Venography (MRV) brain showed venous thrombosis within superior saggital sinus, left transverse sinus and sigmoid sinus. Her thyroid function test showed pretreatment T3 of 2.98 ng/ml T4 of 1.02 mg/ ml and TSH of 0.12 μIU/L. She was kept on anticoagulants and other supportive measures. The patient showed improving status with the conservative management.Nepal Journal of Neuroscience 15:29-31, 2018

Deep Brain Stimulation of bilateral Subthalamic nucleus (STN) following pallidotomy with Parkinsons crisis: A case report

We present a case of 57 years old patient with Idiopathic Parkinsons disease(PD) who had right sided Globus PallidusInternus (GPi) lesioning or pallidotomy as surgical treatment modality of PD. However this patient went into Parkinsons crisis postoperatively which is a rare form of complication. We had to admit in critical care for two weeks before he gradually improved and reached to preoperative state. This patient finally underwent deep brain stimulation(DBS) of bilateral Subthalamic nucleus (STN) and he has improved in terms of Unified Parkinson’s Disease Rating Scale(UPDRS) score.Nepal Journal of Neuroscience 15:40-42, 2018

Antioxidant and cytotoxic activities of Dendrobium moniliforme extracts and the detection of related compounds by GC-MS

Background

The medicinal orchid Dendrobium moniliforme contains water-soluble polysaccharides, phenanthrenes, bibenzyl derivatives, and polyphenol compounds. This study explored the antioxidant and cytotoxic activities of D. moniliforme extracts and detected their bioactive compounds.

Methods

Plant material was collected from the Daman of Makawanpur district in central Nepal. Plant extracts were prepared from stems using hexane, chloroform, acetone, ethanol and methanol. The total polyphenol content (TPC) in each extract was determined using Folin-Ciocalteu’s reagent and the total flavonoid content (TFC) in each extract was determined using the aluminium chloride method. The in vitro antioxidant and cytotoxic activities of each extract were determined using DPPH (2,2-diphenyl-1-picrylhydrazyl) and MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assays respectively. Gas chromatography and mass spectrometry (GC-MS) analysis was used to detect bioactive compounds.

Results

TPC content was highest (116.65 μg GAE/mg of extract) in D. moniliforme chloroform extract (DMC) and TFC content was highest (116.67 μg QE/mg of extract) in D. moniliforme acetone extract (DMA). D. moniliforme hexane extract (DMH) extract showed the highest percentage of DPPH radical scavenging activity (94.48%), followed closely by D. moniliforme ethanol extract (DME) (94.45%), DMA (93.71%) and DMC (94.35%) at 800 μg/ml concentration. The antioxidant capacities of DMC, DMA, DMH and DME, which were measured in IC₅₀ values, were much lower 42.39 μg/ml, 49.56 μg/ml, 52.68 μg/ml, and 58.77 μg/ml respectively than the IC₅₀ of D. moniliforme methanol extract (DMM) (223.15 μg/ml). DMM at the concentration of 800 μg/ml most inhibited the growth of HeLa cells (78.68%) and DME at the same concentration most inhibited the growth of U251 cells (51.95%). The cytotoxic capacity (IC₅₀) of DMM against HeLa cells was 155.80 μg/ml of extract and that of DME against the U251 cells was 772.50 μg/ml of extract. A number of bioactive compounds were detected in both DME and DMM.

Conclusion

The fact that plant extract of D. moniliforme has a number of bioactive compounds which showed antioxidant and cytotoxic activities suggests the potential pharmacological importance of this plant.

Comparative Study of GeneXpert MTB/RIF Assay and Multiplex PCR Assay for Direct Detection of Mycobacterium tuberculosis in Suspected Pulmonary Tuberculosis Patients

Pulmonary tuberculosis (PTB) is one of the major infectious diseases in developing countries. The objective of this study was to compare rapid diagnostics technique, GeneXpert MTB/RIF (GeneXpert) and Multiplex PCR assay (MPCR) targeting IS6110 segment and mpb64 gene for direct detection of Mycobacterium tuberculosis (MTB) in suspected PTB patients. A cross sectional study was carried among 105 sputum samples from suspected PTB patients to evaluate GeneXpert and Multiplex PCR who visited National Tuberculosis Center, Nepal. The patient's sputum samples were used directly for the GeneXpert whereas DNA extraction by CTAB method was followed to process the sample for MPCR. The sensitivity and specificity of GeneXpert and MPCR in smear positive cases was 78.6, 33.3, and 100.0%, 66.7%, respectively (P = 0.125). However, in smear negative cases sensitivity and specificity of both methods exhibited 90.9, 95.2, and 100.0%, 100.0% respectively (P = 0.625). Finally, the sensitivity and specificity of GeneXpert and MPCR were 82.9, 95.3 and 100.0%, 98.5% respectively, (P = 0.549) in pulmonary cases. Comparatively, we observed higher sensitivity and specificity for MPCR than GeneXpert for both smear positive and negative samples. Thus, we recommend MPCR alongside GeneXpert for the better diagnostic accuracy of PTB in a resource-limited country where tuberculosis is endemic.

Transient Cortical Blindness after Digital Subtraction Angiography of Cerebral Vessels

Transient blindness following cerebral angiography is a rare but known entity. We report a case of transient cortical blindness after cerebral angiography. The patient presented with is chemic stroke and the angiography was performed to rule out carotid artery stenosis. The patient, however, gradually regained his vision over a period of 3 days.

Post-Traumatic Glioma: Report of a Case

Development of malignant glioma after trauma is a rare occurrence. Trauma and scarring have been known to be the predisposing factor for the development of meningiomas. Many people have discussed about the development of glioma post trauma but without proper evidence of documents prior to trauma with no evidence of tumor. We present you a case with evidence of not having tumor during trauma. Nepal Journal of Neuroscience, Vol. 14, No. 2,  2017 Page: 43-46

Balloon Test Occlusion for an Option to Decide Whether Simple ICA Ligation is Better Option than Trapping and High Flow Bypass of The Giant ICA Cavernous Aneurysm

Balloon Test occlusion (BTO) is a preoperative angiographic test used to estimate the risk of stroke after permanent therapeutic occlusion of an internal carotid artery (ICA) involved by aneurysms. Temporary balloon occlusion at the cavernous ICA aneurysm neck was performed in an attempt to assess the adequacy of cross flow from the opposite ICA. Adequate fl ow following BTO are preferred to have simple ICA ligation and incase of those who did not pass BTO trapping and high flow bypass is preferred .We have done Right ICA Ligation on our case report.Nepal Journal of Neuroscience, Vol. 14, No. 2,  2017 Page:32-35

Central Pontine Demyelination: A Case Report

Central Pontine Demyelination is a neurological disease caused by rapidly fl uctuating serum osmolality resulting in severe damage of the myelin sheath of nerve cells in the brainstem, more precisely in the area of pons. This condition is associated with electrolyte disorders, especially severe hyponatremia and its rapid correction. Its clinical course is characterized by alterations in the mental status to debilitating neurological status i.e. coma. Chronic hyponatremia and its correction, with or without evaluating safe limit could result in pontine demyelination. Demyelination might also occur with normal sodium levels, and even if serum sodium levels are corrected within safe limits. The objective of this case report is to give a broad perspective on Central Pontine Demyelination and to discuss about the different factors contributing to the demyelination and the various causes, pathophysiology and the management of this condition. Nepal Journal of Neuroscience.

Result of Pallidotomy in Parkinson’s Disease in Nepal

Surgical treatment of Parkinsons disease (PD) has already been an established treatment. Currently pallidotomy, Deep Brain Stimulation (DBS) of Globus pallidus internus (GPi) and Subthalamic nucleus (STN) are available mode of surgical treatment of PD. We have included all patients of idiopathic Parkinosons disease who underwent pallidotomy in Annapurna Neurological Institute and Allied Sciences since 2014. The demographics of the patients have been shown and the patient’s improvement has been shown by Unifi ed Parkinsons Disease Rating Score (UPDRS). We have found that pallidotomy is still a promising surgical modality but it is advised to perform either unilaterally or staged bilaterally with at least 3 months gap inbetween.Nepal Journal of Neuroscience.
