Published: October 2020

BACKGROUND: Radiation risk from computed tomography (CT) is always an issue for patients, especially those in clinical conditions in which repeated CT scanning is required. For patients undergoing repeated CT scanning, a low-dose protocol, such as sparse scanning, is often used, and consequently, an advanced reconstruction algorithm is also needed. OBJECTIVE: To develop a novel algorithm used for sparse-view CT reconstruction associated with the prior image. METHODS: A low-dose CT reconstruction method based on prior information of normal-dose image (PI-NDI) involving a transformed model for attenuation coefficients of the object to be reconstructed and prior information application in the forward-projection process was used to reconstruct CT images from sparse-view projection data. A digital extended cardiac-torso (XCAT) ventral phantom and a diagnostic head phantom were employed to evaluate the performance of the proposed PI-NDI method. The root-mean-square error (RMSE), peak signal-to-noise ratio (PSNR) and mean percent absolute error (MPAE) of the reconstructed images were measured for quantitative evaluation of the proposed PI-NDI method. RESULTS: The reconstructed images with sparse-view projection data via the proposed PI-NDI method have higher quality by visual inspection than that via the compared methods. In terms of quantitative evaluations, the RMSE measured on the images reconstructed by the PI-NDI method with sparse projection data is comparable to that by MLEM-TV, PWLS-TV and PWLS-PICCS with fully sampled projection data. When the projection data are very sparse, images reconstructed by the PI-NDI method have higher PSNR values and lower MPAE values than those from the compared algorithms. CONCLUSIONS: This study presents a new low-dose CT reconstruction method based on prior information of normal-dose image (PI-NDI) for sparse-view CT image reconstruction. The experimental results validate that the new method has superior performance over other state-of-art methods.

Biodiversity of fishes in musi estuary, South Sumatra, Indonesia.Â Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 192-198.The high activity in the Musi estuary will have an impact on fishes diversity. This research aimed to analyse the biodiversity of fishes in the Musi estuary in South Sumatra. An experimental fishing method was used for data collection by fishing ground following the local fishermen habit using gillnet millennium. The abundance of fish species found were 21 species and 16 families. The main catch was Hemibagrus nemurus with a high relative abundance (RA) of 35.4% but the high availability frequency of 100% is Eleutheronema tetradactylum. The average value of the moderate diversity index (H'= 1.47), the moderate evenness index (J'= 0.48) and the low dominance index (D= 0.32). This condition shows that the community structure of the species captured by the gill net is in a fairly stable condition with the number of species that are spread fairly evenly and no species dominate each other.

Published: October 2020

Introduction: A traumatic brain injury (TBI) is an injury to the brain caused by an impact to the head. TBI represents a huge global medical and public health problem across all ages and in both civilian and military populations. TBI is characterized by great heterogeneity in terms of etiology, mechanism, pathology, severity and treatment with widely varying outcomes.
Objective: To determine the pattern and outcome of traumatic brain injuries in victims reported to emergency and casualty (E&C) department following intensive care with or without surgical intervention.
Materials and Methods: This prospective type of observational study was conducted at Neurosurgery department of Combined Military Hospital, Dhaka from October 2013 to March 2017. A total of 675 head injury patients with TBI were assessed with gender, age, cause and type of trauma, GCS on admission, associated other injuries, time lapsed from trauma to hospitalization and care given. The outcome was measured after 72 hours using Glasgow Outcome Scale (GOS).
Results: The incidence of TBI was 47.03% among the head injury patients. Common age group was 21-30 years (43.7%) and male victims (66.55%). RTA was the most frequent cause (50.05%) of TBI and the most common pathophysiological cause of TBI was subdural haemorrhage (SDH)(35%) followed by extradural haemorrhage (EDH)(27%). Most patients (45%) had mild TBI. Surgical intervention was required in 45% patients of TBI mainly for the SDH, EDH which had significant positive effect on the TBI patient’s outcome. The majority of patients (77%) had good outcome which included recovery (51.85%) and moderate disability (25.48%). The poor outcome was observed in 23% patients which included death (7.40%), persistent vegetative state (3.11%), severe disability (12.14%) and it was associated with older age, severe TBI (GCS<8 on admission), associated other injuries and delayed resuscitative care and interventions.
Conclusion: TBI was common among the young adults male. The RTA was the leading cause of TBI. The factors that influence the outcome of TBI include patient’s age, severity of TBI, associated injuries and delayed resuscitative care.

A case of Young Stroke due to Moyamoya Disease
Authors: Razzak Md Abdur , Kawnayn Ghulam , Naznin Fateha , Rahman Quazi Audry Arafat 
Published: October 2020

Moyamoya disease is a disease in which certain arteries in the brain are constricted. Blood flow is blocked by the constriction, and also by blood clots (thrombosis). A collateral circulation develops around the blocked vessels to compensate for the blockage, but the collateral vessels are small, weak, and prone to bleeding, aneurysm and thrombosis which may result in TIA, recurrent ischemic or hemorrhagic stroke or seizure. The disease may manifest in pediatric age or young adults. In May 2019 we have diagnosed a young lady with Moyamoya disease who presented with right sided hemiplegia, motor aphasia and dysphagia. She was labeled as hypertensive 6 months prior to this event and used to take anti-hypertensive irregularly and gave past history of occasional headache. Her CT scan and MRI of brain revealed left sided ischemic infarct involving frontotemporoparietal region and cerebral angiogram revealed narrowing of left MCA and non-visualization of distal part. There is extensive fine collaterals (Moyamoya vessels) giving the appearance of puffed smoke. The right ACA and MCA were also narrowed with appearance of early collateral vessels. She was treated with aspirin, PPI, NG feeding, antihypertensive medication, physiotherapy, rehabilitation therapy and other supportive care. His condition gradually improved and discharged on 2.7.19. He was referred to Department of Neurosurgery for cerebral revascularization by STA-MCA (superficial temporal and middle cerebral arteries) bypass surgery after stabilization and MR perfusion study.

Study on Sensitivity of Microphysics for the Simulation of Rainfall for the Month of May 2015 over Bangladesh using High Resolution WRF-ARW Model
Authors: Khan Md Salman , Alam MM 
Published: October 2020

In this research the Advanced Research WRF (ARW) model v3.8.1 has been used to simulate the rainfall of May 2015 all over Bangladesh. The model was configured in nested domain with 18 and 6 km horizontal grid spacing with 100 × 96 and 103 × 127 grids in the east-west and north-south directions, respectively with 30 vertical levels. The Lin et al., WSM6, Thomson, Morrison Double-Moment (M-2Mom), Stony Brook University (SBU), and WDM6 microphysics schemes coupling with Kain-Fritsch (KF) cumulus parameterization (CP) scheme have been used to simulate the monthly total rainfall, heavy rainfall, monthly rainy days and heavy rainy days for the month of May 2015 at all meteorological stations of Bangladesh. The simulated results are compared with the observed results of 33 meteorological stations of Bangladesh Meteorological Department (BMD) and Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN) output. Relative standard deviation of all observed, PERSIANN and model simulated parameters have been analyzed and compared. The maximum monthly observed rain in May 2015 at Sylhet was 752 mm but WSM6, M-2Mom and WDM6 schemes have simulated 831, 788 and 742 mm for day 1 prediction; WSM6, WDM6 and SBU-Lin schemes have simulated 757, 916 and 981 mm for day 2 prediction and WSM6 and WDM6 schemes have simulated 741 and 925 mm for day 3 prediction, respectively and all other MPs have simulated much higher rainfall at domain (D1). The WDM6, M-2Mom and Lin et al. schemes have simulated 744, 807 and 923 mm for day 1 prediction, WSM6 and WDM6 schemes have simulated 714 and 877 mm for day 2 predictions and WSM6, SBU-Lin and Lin et al. schemes have simulated 802 and 913 and 998 mm, respectively for day 3 predictions at domain (D2). The relative standard deviation (RSD) has minimum at D1 and D2 for WDM6 scheme for day 1 prediction and WSM6 scheme for day 2 and day 3 predictions for the monthly total rainfall and heavy rainfall of May 2015. The results suggest that as the forecast time increased the amount of total rain and also heavy rain is increased. As a result RSD is also increased for all MPs. WDM6 scheme gives the better performance of rainfall and rainy days all over the country.

On the Simulation of Lightning and Flash Flood Producing Thunderstorms in the Northeastern Bangladesh
Authors: Karmakar Samarendra , Das Mohan Kumar 
Published: October 2020

This study is an attempt to simulate the tropospheric conditions associated with lightning and thunderstorms, which occurred during 28-30 March 2017 over northeastern Bangladesh using WRF model. At Sylhet, rainfall amounts of 119 mm and 134 mm are found to occur on 29 March and 31 March 2017 respectively. The continuous very heavy rainfall has been responsible for the devastating flash flood in Sunamganj and adjoining areas in 2017. The study shows that forecasting of lightning and flash flood producing thunderstorms is possible by analyzing different meteorological parameters simulated by WRF Model. The simulated parameters are rainfall, sea level pressure, geopotential height (m), Convective Available Potential Energy (CAPE), winds at various tropospheric levels, cloud water mixing ratio and ice water mixing ratio, vorticity and x, y, z wind components. A low pressure area and strong circulations are found to develop over West Bengal and adjoining Bangladesh with extended troughs towards northeast, having strong flows of southwesterly to southsoutheasterly winds distinctly visible at low level over the Bay of Bengal and Bangladesh. Interaction of northwesterly flows of winds at 500 hPa level and southerly flow coming from the Bay of Bengal is found to produce sufficient instability in the troposphere to develop severe thunderstorms which when moved over northeast Bangladesh/Meghalaya have become stronger due to orographic influence, thereby become lightning and flash flood producing thunderstorms. The thunderstorms become more marked due to the presence of westerly jet stream of 40 ms-1 over Bangladesh and India. The persisting characteristics of the circulation over West Bengal and Bangladesh, the micro-circulation, the intense geopotential low at 850 hPa and their eastward extension have been responsible for continuous heavy to very heavy rainfall over Sylhet and Meghalayan region, causing wide-spread intense flash floods over there. On 29 March 2017, cloud water mixing ratio is found to range from 160 to 1100 mgm-3 and ice water mixing ratio from 27 to 100 mgm-3 at different locations. The maximum cloud water mixing ratio values are 1100 and 1000 mgm-3 at Cherrapunji and Sylhet respectively, where torrential rain has occurred. The high values of cloud water mixing ratio and ice water mixing ratio in the upper troposphere over northeastern Bangladesh and adjoining areas indicates significant convection in the troposphere and have been responsible for moderate to severe lightning. The distribution of CAPE has also shown increasing higher values, indicating moderate to severe lightning.

A pandemia da COVID-19 tem se apresentado como desafio para o Brasil, ao registrar mais de 134 mil óbitos em sete meses e mais de 4,4 milhões de infectados. Pesquisadores de várias instituições de ensino e empresas se empenharam para desenvolver respiradores mecânicos alternativos devido ao seu alto custo e demanda. Este estudo objetiva analisar iniciativas da comunidade científica no desenvolvimento de respiradores mecânicos no Brasil. É uma revisão narrativa subdivida em duas etapas: 1) identificação dos modelos de respiradores mecânicos desenvolvidos durante a pandemia e 2) realização de um fórum de discussão com profissionais de diversas áreas acadêmicas do Nordeste, onde foram destacados temas sobre o impacto da COVID-19 no Brasil, necessidade e diagnóstico para utilização de respiradores mecânicos e critérios de autenticidade científica. Acredita-se que os projetos de respiradores mecânicos são relevantes não apenas para o momento vigente, mas também para o pós-pandemia.

Published: October 2020

A retrospective analysis of 136 medical histories of patients with eye injuries who applied to the city and regional centers of emergency ophthalmological care and were hospitalized in two specialized ophthalmological departments during one calendar year was carried out. 89% of patients were men, 11% were women; 20% contacted hospitals in winter, 21% – in spring, 30% – in summer and 29% – in autumn. Out of 139 injured eyes, 50% were wounded, 40% were contused, 10% had burns. In cases of eye injuries, 7 (10%) were injuries of the appendages of the eye, 57 (81%) were penetrating injuries, 66% were corneal injuries, 25% – scleral injuries, 9% – corneal-scleral injuries, all of which were severe; 3% – non-penetrating injuries of the cornea, 6% – penetrating injuries of the orbit. Among 56 contused eyes, appendages of the eye were damaged in 4 (7%) eyes, all of them were of 2nd degree of severity. Eyeball damage was diagnosed in 35 (63%) eyes: 17 were of 2nd degree of severity, 15 – of 3rd degree of severity, 3 – of 4th degree of severity. Multisystem injuries of the eyeball and appendages of the eye were diagnosed in 17 (30%) eyes. Corneal, conjunctival and eyelid burns of the 2nd degree were diagnosed in 9 eyes, while burns of the 3rd degree were diagnosed in 4 eyes. All cases were chemical burns. 87% cases were civilian injuries, 11.5% were work injuries, while 1.5% were caused by criminal actions. In 2 eyes with non-penetrating corneal injuries, the visual acuity increased after discharge from hospital. Out of 57 eyes with penetrating injuries, the visual acuity increased in 34 eyes and decreased in 8 eyes; in 3 cases of visual acuity decrease, an ophthalmectomy was performed; in 15 eyes the visual acuity remained unchanged.

Visualization and assessment of the anterior surface of the cornea by corneal topography (Part II)
Authors: Andrienko G. V. 
Published: October 2020

Goal. To introduce ophthalmologists and optometrists to the basics of corneal topography. Corneal topography is the main method for assessing corneal surface regularity, the violation of which leads to a deterioration in its refractive properties and a decrease in the quality of vision. The first part of the workshop (The EYE GLAZ. 2020 (22), № 2) presented the main types of topography maps and keratometry data. In the second part, considerations are made regarding mastering the skills of capturing high-quality images and choice of color maps for analysis. Topography patterns as well as topographic signs of keratoconus are also discussed. Conclusion. Placido-based corneal topographers are a useful tool for evaluating the anterior corneal surface, fitting contact lenses and diagnosing keratoconus. Slit-scanning topographers, additionally, are capable of corneal pachymetry and analyzing the posterior surface of the cornea, which allows for carrying out a more detailed assessment and diagnosing keratoconus at preclinical stage.
