Authors: Hanalioglu Sahin , Sahin Omer Selcuk , Turkoglu Mehmet Erhan 
Published: January 2020

This video demonstrates the resection of an anterolateral mesencephalic cavernous malformation (CM) through a transsylvian/transuncal approach. A 10-year-old girl presented with progressive headache and left-sided spastic hemiparesis. Neuroimaging revealed a 20-mm CM located in the right anterolateral midbrain/cerebral peduncle. After orbitozygomatic craniotomy and wide sylvian fissure opening, the oculomotor nerve was dissected and separated from the temporal lobe. Partial resection of the uncus allowed access to the CM through the oculomotor-tentorial triangle. The CM was excised in a piecemeal fashion. Postoperative imaging confirmed the gross-total resection. The patient had no additional neurological deficits postoperatively. Her left hemiparesis almost completely resolved at the 12-month follow-up.The video can be found here: https://youtu.be/Jb_EaWbn5LU.

Published: January 2020

Brainstem cavernomas are benign, angiographically occult, low-flow lesions and constitute 18%–35% of intracranial cavernomas.4,6 They are known to have an annual rupture risk of 2%–6%,2,5 and once symptomatic, they frequently cause progressive neurological morbidity. A 22-year-old lady presented with progressive profound neurologic deficits from three distinct hemorrhages over 2 months. Surgery was indicated given the aggressive natural history, and the lesion now presented to the surface with displacement of corticospinal tracts noted on diffusion tensor imaging.1,7 We describe a surgical technique via an orbitozygomatic transsylvian pretemporal approach with uncal resection to open the oculomotor-tentorial window and resect the lesion.3The video can be found here: https://youtu.be/j5yYp4OsaRc.
Pretemporal transcavernous transtentorial approach for right pontine cavernous malformation
Authors: Hsu Xavier T. J. , Liao Chih-Hsiang , Lin Chun-Fu , Hsu Sanford P. C. 
Published: January 2020

A 57-year-old man presented with acute changes in mental status. Brain CT showed a high-density lesion at the pons. Brain MRA revealed a very slow-flow vascular lesion at the right aspect of the pons, about 3.9 ⋅ 3.0 ⋅ 3.0 cm3, compatible with a pontine cavernous malformation (CM). Gross-total removal was achieved. In this approach, a wider surgical corridor was obtained by opening the Meckel’s cave and cutting the tentorium. For a midline attack point on the pons, additional removal of the posterior clinoid process can meet the goal. In the authors’ opinion, this approach is safe and effective in selected ventrolateral pontine CMs.The video can be found here: https://youtu.be/moHqEkp5eCA.
Resection of brainstem cavernous malformation via perifacial zone through retrosigmoid supracondylar approach
Authors: Matsushima Ken , Kohno Michihiro , Bertalanffy Helmut 
Published: January 2020

Hemorrhagic brainstem cavernous malformations carry a high risk of progressive neurological deficits owing to recurrent hemorrhages and hence require complete surgical resection while minimizing damage to the dense concentration of nuclei and fibers inside the brainstem. To access lesions inside the lower pons, the senior author (H.B.) has preferred to approach the lesions via the “perifacial zone” through the pontomedullary sulcus from the inferior surface of the pontine bulge for more than 20 years.1,2 This video demonstrates a case of a cavernous malformation inside the lower pons, which was surgically treated via the pontomedullary junction through the retrosigmoid supracondylar approach in a half-sitting position. The lesion was completely removed in piecemeal fashion through a tiny incision on the sulcus, which did not cause any new neurological deficits. The modified Rankin Scale improved from 4 before the surgery to 1, and the patient had no recurrence during the 2 years of follow-up. The advantage of this access and the dissection techniques for this challenging lesion are introduced, based on our experience with more than 230 surgeries of brainstem cavernoma.The video can be found here: https://youtu.be/0H_XqkQgQ9I.

Published: January 2020

Adult spinal deformity (ASD) is an increasing disease entity as the population ages. An emerging minimally invasive surgery (MIS) option for the treatment of ASD is the oblique lumbar interbody fusion (OLIF), which allows indirect foraminal decompression of stenosis as well as segmental deformity correction (DiGiorgio et al., 2017). The authors utilize computer-assisted navigation with OLIF to reduce radiation exposure and improve time efficiency. The authors present a video of navigated oblique lumbar interbody fusion at L3–5 followed by open posterior screw-rod fixation.The video can be found here: https://youtu.be/zKDT7PhMYf8.

Published: January 2020

Three-column osteotomies (3COs) can achieve significant alignment correction when revising fixed sagittal plane deformities; however, the technique is associated with high complication rates. The authors demonstrate staged anterior-posterior surgery with L5–S1 ALIF (below a prior L3–5 fusion) and multilevel Smith-Petersen osteotomies to circumvent the morbidity associated with 3CO. The patient was a 67-year-old male with three prior lumbar surgeries who presented with back and leg pain. Imaging demonstrated lumbar flat back deformity and sagittal imbalance. The narrated video details key radiological measurements, operative planning and rationale, surgical steps, and outcomes. The patient provided written, informed consent for publication of this illustrative case.The video can be found here: https://youtu.be/wv4W9D9fUPc.

Published: January 2020

Sporotrichosis is a globally prevalent subcutaneous mycosis commonly acquired through traumatic inoculation. A 66-year-old woman with underlying systemic lupus erythematosus (SLE) presented initially with a painful non-healing nodule on her right thumb. There was no history of traumatic contact with soil, plants or animals. She was started on an antibiotic but developed multiple nodules on her right forearm which appeared to spread proximally. Culture of her skin biopsy specimen yielded Sporothrix schenckii. The lesions were successfully treated with oral itraconazole. In conclusion, a history of traumatic inoculation need not always be present in SLE patients with sporotrichosis and obtaining a laboratory diagnosis is crucial for those presenting with nodular skin lesions that spread proximally

Introduction: Tuberculosis (TB) is one of the world’s deadliest disease. Presently, one fourth of the world’s population is thought to be infected with TB. Early diagnosis of tuberculosis is very important for therapeutic reasons and to control the spread of infection. The purpose of this study was to compare the efficacy of fluorescence (FL) microscopy in comparison to Ziehl- Neelsen (ZN) staining
Methods: A cross-sectional study of 310 TB suspects attending Dhaka Medical College hospital subjected to four sputum examinations by ZN and FM. Löwenstein- Jensen culture was used as the gold standard. Of 310 suspects enrolled, 304 (98%) had a complete diagnostic work-up involving three sputum specimens for ZN and FM, culture and chest X-ray (CXR).
Result: Out of 320 suspected case, 10 persons were out of our study. Among 310, 204 suspected case sputum culture was positive. Though we took sputum culture as gold standard, so there were 204 tuberculosis patient present in our study. Out of 204 TB patient 125 (61.2%) cases were positive in ZN staining. Negative ZN methods were also high 79 (39.7%) which indicate less sensitivity. On the other hand, FM methods showed 193 (94.6%) cases positive out of 204 sputum culture positive patient. It also presence of 11 cases which showed negative result in this methods. From this data we can assumed higher sensitivity of FL methods from ZN methods. Here 106 cases were culture negative. Out of these 106 people only 05 persons were positive in ZN staining whereas 10 persons were find to positive in FL methods. This message demonstrates us that specificity of ZN methods are slightly higher over FM methods. Overall sensitivity of ZN microscopic (61%)) methods are much lower than FL microscopic methods (95%). On the other hand, specificity was slightly reverse, which showed 95.5% in case ZN methods and 91% in FL methods. It also demonstrates that positive predictive value of ZN microscopy (96%) is slightly higher than FL microscopic (95%) methods but negative predictive value showed gross difference ZN microscopic (56%) and FL microscopic (89%) methods.
Conclusions: The FL methods is more sensitive and shortens the diagnostic process of tuberculosis. Consequently, more patients can be put on a regimen for smear-positive TB, contributing to improved treatment and reducing transmission. For that Front-loaded (FL) microscopic approach may apply for early diagnosis and detection of tuberculosis.

Fecundity estimation has obvious significance in aquaculture, since the size of brood stock, amount of rearing facilities and necessity of other equipment’s are dependent on fecundity. The study has been conducted on fecundity estimation of Indian potasi, Neotropius atherinoides, based on 202 females collected from the Kangsha River flowing through Netrokona district during the period from January to June 2013. The standard length (SL) range of female were 47-66, 50-64, 57-68, 50-66, 56-66 and 60-76 mm and range of body weight were 1.07-3.56, 1.23-3.35, 2.36-3.81, 1.69-4.31, 2.33-5.59 and 3.18-5.14 g in January, February, March, April, May and June, respectively. The mean Gonado somatic indices (GSI) were very low from January to March but these were abruptly high during subsequent three months. Based on mean GSI the spawning season of this species was assumed from April to June over the study period. Scatter plot of standard length with corresponding GSI revealed that the minimum length of mature female was 50 mm SL. Egg diameter frequency distribution of a mature ovary showed almost only one major mode of egg size suggested that the fish is a single spawner, and summation of eggs in that mode was regarded as the fecundity of a female Indian potasi. The regression equation of the relationship between standard length and fecundity was as, Fecundity = 0.0017 SL 3.55. The relative fecundity and the absolute fecundity of a fish having SL of 62 mm was 1477 per g and 3921, respectively based on F-SL relationship. The relationship between body weight and fecundity was as, Fecundity = 1371.3 BW-650.8. The absolute fecundity of a fish having BW of 3.51 g was 4162 respectively based F-BW relationship. The relationship between ovary weight and fecundity was as, Fecundity = 6244.3 OW + 967.52. The absolute fecundity of a fish having ovary weight of 3.51 g was 7211 based F-OW relationship. The correlation coefficient of all above analyses were very high (>0.755) attributing that standard length, body weight and gonad weight were highly positively correlated with fecundity of Indian Potasi, Neotropius atherinoides.

Neuroleptic Malignant Syndrome Associated with Haloperidol
Authors: Bhuiyan Md Fajlul Kabir 
Published: January 2020

A 42-year-old adult schizophrenic patient developed high fever (106 degree Fahrenheit), mental state changes and muscle rigidity after treatment with parenteral haloperidol. Neuroleptic malignant syndrome (NMS) associated with haloperidol was suspected. Other differentials were excluded. Haloperidol was discontinued and prompt treatment with bromocriptine and lorazepam was started resulting in a good recovery. Because of the temporal relationship between the patient's improvement with the discontinuation of haloperidol and treatment with lorazepam and bromocriptine, the diagnosis was believed to be haloperidol-induced NMS.

MIGRACIONES Y MIGRANTES EN LOS MEDIOS DE PRENSA EN CHILE: LA DELICADA RELACIÓN ENTRE LAS POLÍTICAS DE CONTROL Y LOS PROCESOS DE RACIALIZACIÓN
Authors: Stefoni Carolina , Brito Sebastian 
Published: January 2020

El presente artículo analiza la superposición del discurso político del actual gobierno de Presidente Piñera (2018-2022) y el discurso de los medios de comunicación respecto de la migración y de los migrantes. El artículo plantea que en ambos discursos se observa una estrecha relación entre la forma de representar a los migrantes (racializada y estereotipada) y las políticas de control que se han venido sucediendo a través de medidas implementadas en la actual administración. Para ello desarrollamos tres ideas centrales: los medios de comunicación han sido un espacio hegemonizado por el Ministerio del Interior; los medios reproducen la idea de migración como un problema y refuerzan ciertos estereotipos asociados a la migración haitiana (pobre, marginal, vulnerable) y venezolana (situación de crisis, emergencia, desborde) y finalmente el gobierno ha sido eficaz en la instalación del ideologema “ordenar la casa” que actúa como metáfora dominante que encierra una posición ideológica, reduciendo la realidad a una idea sencilla con alto poder manipulador. Se revisaron 197 noticias aparecidas en los medios de comunicación entre abril de 2018 y agosto de 2019 en medios de prensa disponibles on-line.
Епидемиология на хередитарната оптична невропатия на Лебер
Authors: Митова Елена , Стефанов Георги 
Published: January 2020

Хередитарната оптична невропатия на Лебер (Leber’s hereditary optic neuropathy, LHON) е митохондриална невродегенеративна болест, засягаща зрителния нерв. Това е една от най-честите наследствени оптични невропатии. Причинява се от точкови мутации в митохондриалната ДНК и последваща митихондриална дисфункция. Заболяването се характеризира с безболезнена загуба на централното зрение – последователно или едновременно в двете очи. Проявява се в млада възраст и засяга предимно мъжкия пол.
LHON е първото клинично описано митохондриално заболяване, а в някои публикации е споменавано и като найчестото. Изучаването на епидемиологията на болестта на Лебер е затруднено. Заболяването има многообразна молекулярно-генетична характеристика, която търпи непрекъснато допълване. При множеството проучвания, обхващащи определени фамилни кохорти, са използвани разнообразни възрастови и други ограничения, което е довело до отразяване на различни фактори в етиологията имолекулярно-генетична характеристика на LHON.
Настоящата публикация има за цел да анализира епидемиологични данни за хередитарната оптична невропатия на Лебер и да предостави епидемиологична оценка за разпространението на това заболяване в България.

Abstract
With Gaia Data Release 2, the astronomical community is entering a new era of multidimensional surveys of the Milky Way. This new phase-space view of our Galaxy demands new tools for comparing observations to simulations of Milky Way-mass galaxies in a cosmological context, to test the physics of both dark matter and galaxy formation. We present ananke, a framework for generating synthetic phase-space surveys from high-resolution baryonic simulations, and use it to generate a suite of synthetic surveys resembling Gaia DR2 in data structure, magnitude limits, and observational errors. We use three cosmological simulations of Milky Way-mass galaxies from the Latte suite of the Feedback In Realistic Environments project, which feature self-consistent clustering of star formation in dense molecular clouds and thin stellar/gaseous disks in live cosmological halos with satellite dwarf galaxies and stellar halos. We select three solar viewpoints from each simulation to generate nine synthetic Gaia-like surveys. We sample synthetic stars by assuming each star particle (of mass 7070 M
⊙) represents a single stellar population. At each viewpoint, we compute dust extinction from the simulated gas metallicity distribution and apply a simple error model to produce a synthetic Gaia-like survey that includes both observational properties and a pointer to the generating star particle. We provide the complete simulation snapshot at z = 0 for each simulated galaxy. We describe data access points, the data model, and plans for future upgrades. These synthetic surveys provide a tool for the scientific community to test analysis methods and interpret Gaia data.
Preoperative Templating and Biomechanics in Total Hip Arthroplasty
Authors: Schmalzried Thomas P 
Published: January 2020

abstract
Preoperative templating is an essential ingrethent of a successful hip arthroplasty. The socket template is positioned first to establish the center of rotation of the reconstruction. For femoral templating, a surgeon should not only consider the part inside the bone (the size of the component), but should also consider the part outside the bone, which determines limb length and biomechanics! parameters such as the abductor muscle and ioint reaction forces. Medializing the hip center of rotation and increasing the horizontal femoral offset can improve clinical outcomes and reduce polyethylene wear. Modern modular systems allow limb length adjustment and biomechanical improvement for a range of patients.

Optimizing the Femoral Component Cement Mantle in Total Hip Arthroplasty
Authors: Dennis Douglas A , Lynch Christopher B 
Published: January 2020

abstract
Aseptic loosening is a common cause of long-term failure of cemented femoral components in hip arthroplasty. Initiation of aseptic loosening has been associated with suboptimal cement mantle thickness and uniformity with the resultant progressive development of detrimental cement mantle defects. Long-term success is highly dependent on maintaining and protecting the integrity of the cement mantle and its interfaces primarily by decreasing cement mantle stresses. High cement stresses that initiate debonding and cement fracture can be controlled and minimized through the use of various surgical techniques that assist in creating an optimally thick, symmetric, and homogeneous cement mantle.
