Medical Data Feature Learning Based on Probability and Depth Learning Mining: Model Development and Validation
Authors: Yang Yuanlin , Li Dehua 
Published: May 2020

Background
Big data technology provides unlimited potential for efficient storage, processing, querying, and analysis of medical data. Technologies such as deep learning and machine learning simulate human thinking, assist physicians in diagnosis and treatment, provide personalized health care services, and promote the use of intelligent processes in health care applications.

Objective
The aim of this paper was to analyze health care data and develop an intelligent application to predict the number of hospital outpatient visits for mass health impact and analyze the characteristics of health care big data. Designing a corresponding data feature learning model will help patients receive more effective treatment and will enable rational use of medical resources.

Methods
A cascaded depth model was successfully implemented by constructing a cascaded depth learning framework and by studying and analyzing the specific feature transformation, feature selection, and classifier algorithm used in the framework. To develop a medical data feature learning model based on probabilistic and deep learning mining, we mined information from medical big data and developed an intelligent application that studies the differences in medical data for disease risk assessment and enables feature learning of the related multimodal data. Thus, we propose a cascaded data feature learning model.

Results
The depth model created in this paper is more suitable for forecasting daily outpatient volumes than weekly or monthly volumes. We believe that there are two reasons for this: on the one hand, the training data set in the daily outpatient volume forecast model is larger, so the training parameters of the model more closely fit the actual data relationship. On the other hand, the weekly and monthly outpatient volume is the cumulative daily outpatient volume; therefore, errors caused by the prediction will gradually accumulate, and the greater the interval, the lower the prediction accuracy.

Conclusions
Several data feature learning models are proposed to extract the relationships between outpatient volume data and obtain the precise predictive value of the outpatient volume, which is very helpful for the rational allocation of medical resources and the promotion of intelligent medical treatment.

<b>A EXTRAFISCALIDADE DO IPTU COMO FERRAMENTA DE ENFRENTAMENTO CONTRA AS GENTRIFICAÇÕES E DE FORTALECIMENTO DA FUNÇÃO SOCIAL DA PROPRIEDADE</b><br/>THE EXTRAFISCALITY OF IPTU AS A COOLING TOOL AGAINST GENTRIFICATIONS AND STRENGTHENING THE PROPERTY'S SOCIAL FUNCTION

Esta pesquisa tem por objeto o viés extrafiscal do imposto predial e territorial urbano (IPTU) na perspectiva do dever fundamental de contribuir para o desenvolvimento das cidades. A gentrificação é uma prática comum na América Latina que retira da classe trabalhadora o direito à moradia para concretizar tão somente interesses imobiliários. Assim sendo, esse artigo se justifica em razão da segregação socioespacial causada pela especulação imobiliária no meio urbano, violando os objetivos da Constituição Federal de 1988. Utilizar-se-á como método o positivismo lógico, através da análise do IPTU e da função social da propriedade na Constituição Brasileira de 1988 e nas legislações vigentes. O problema central que se pretende enfrentar é a possibilidade de os tributos municipais combaterem ou não a gentrificação urbana. A partir desta problemática, têm-se como objetivos: 1) analisar se a expansão imobiliária causa um processo de exclusão social e fere os objetivos constitucionais; 2) verificar se existe fortalecimento da função social da propriedade com a aplicação do IPTU e uma concretização ao direito à moradia; 3) estudar se a extrafiscalidade serve como mecanismo de combate à gentrificação. Parte-se da hipótese de que a extrafiscalidade tributária pode servir como mecanismo de minimização das contradições geradas pelo processo de gentrificação urbana.
Las metamorfosis de la Colección Tezontle. El primer catálogo literario del Fondo de Cultura Económica
Authors: Cervantes Becerril Freja Ininna 
Published: May 2020

En este ensayo se analiza la conformación del catálogo literario de la Colección Tezontle del Fondo de Cultura Económica. Para ello se estudia el origen de las publicaciones literarias en el desarrollo del proyecto fundador de la editorial, y se atienden las peculiaridades de la colección entre 1940 y 1965. En este periodo de la historia del Fondo, que corresponde a las dos primeras direcciones de Daniel Cosío Villegas y Arnaldo Orfila Reynal, se observa la aparición de las primeras ediciones literarias con el sello Ediciones Tezontle y Tezontle que hasta 1954 el Fondo distribuyó y comercializó “desinteresadamente”. A partir del Catálogo general de 1955, la serie Tezontle aparece como una colección más de la empresa editora, sumando su catálogo al resto de las publicaciones. Esta transición de sello independiente a colección exigió una metodología propia para el estudio de su naturaleza pragmática, la cual se relaciona con las políticas culturales de los editores del Fondo y su práctica editorial.

Way Kambas National Park (WKNP) is home of five protected big mammals including sumatran elephants. It shares its border with 22 of 37 villages surrounding the national park. Understanding their existence in the wild is a priority, and wildlife genetics is a crucially needed. Besides poaching and habitat fragmentation, wildlife-human conflict is one big issue. Elephant Training Center (ETC) in WKNP is built for semi in-situ conservation effort on captive sumatran elephants that mainly have conflict histories with local people. Participative observation and bio-molecular analysis were conducted to learn the importance of captive Sumatran elephant for conservation effort. Through captive sumatran elephants, database and applicable methods are expected to be developed supporting the conservation of their population in the wild. Participative observation and molecular identification was carried on captive sumatran elephants in ETC, WKNP under multiple year Terapan grant of Ministry of Research and Technology Higher Education, Indonesia. Gene sequence and cytological analyses showed that the captive sumatran elephants are closely related and tend to be domesticated. Translocation among ETC to avoid inbreeding, and maintaining the captive sumatran elephant as natural as possible are highly recommended. Developing genetic database can be a reference for both captive and wild sumatran elephants.

Kebebasan berkontrak bukanlah kebebasan tanpa batas. Kontrak standar pengadaan barang dan jasa pemerintah merupakan salah satu pembatas kebebasan berkontrak. Pembentukan dan pengaturan hak dan kewajiban yang termuat dalam kontrak pengadaan barang dan jasa, didasarkan pada peraturan standar yang termuat dalam Standar Dokumen Pengadaan/Standar Dokumen Pengadaan Secara Elektronik. Penelitian ini bertujuan untuk menganalisis keberlakuan prinsip kebebasan berkontrak dalam kontrak standar, serta bentuk kebebasan berkontrak dalam kontrak standar pengadaan barang dan jasa pemerintah. Melalui penelitian yuridis normatif, penelitian ini menemukan kontrak standar bertentangan dengan prinsip kebebasan berkontrak, kemudian ditemukan bentuk kebebasan berkontrak dalam kontrak pengadaan barang dan jasa pemerintah yaitu pada tahapan pra kontraktual. Pada tahapan kontraktual dan tahapan post kontraktual, kebebasan berkontrak hanya merupakan pelaksanaan dari ketentuan undang-undang. Untuk itu, rekomendasi dari penelitian ini adalah perlu dilakukan perubahan terhadap ketentuan mengenai hak dan kewajiban para pihak baik pada tahap pra kontraktual, kontraktual, maupun post kontraktual pada kontrak pengadaan barang dan jasa.

Published: May 2020

Background:
Granular cell tumor (GCT) of the sellar region is a rare tumor of the sellar and suprasellar regions that originate from the neurohypophysis. This tumor is very difficult to differentiate from other pituitary neoplasms, such as pituitary adenoma, pituicytoma, and spindle cell oncocytoma. We report a rare case of GCT arising from the posterior pituitary of the sellar region and suggest a useful indicator for accurate diagnosis and pitfalls for surgical procedures.

Case Description:
A 42-year-old woman was admitted to our hospital with bitemporal hemianopsia. Neuroimaging showed a large pituitary tumor in the sellar and suprasellar regions with a hypointense part on T2-weighted magnetic resonance imaging, and the enhanced anterior pituitary gland was displaced anteriorly. Laboratory findings showed mild hyperprolactinemia. Subtotal resection of the tumor was achieved using an endoscopic endonasal transsphenoidal approach. Histological findings showed round or polygonal cells with abundant granular eosinophilic cytoplasm staining strongly for thyroid transcription factor 1. The tumor was, therefore, diagnosed as a GCT of the sellar region, belonging to tumors of the posterior pituitary. After surgery, visual impairment and anterior pituitary function were improved. Follow-up neuroimaging after 1 year showed no signs of recurrence.

Conclusion:
GCT of the sellar region is difficult to diagnose on routine neuroimaging. Therefore, accurate diagnosis requires careful identification of clinical signs, magnetic resonance imaging including hypointensity on T2-weighted imaging, and analysis of combined morphological and immunohistochemical studies.
Combined petrosal approach for resection of petroclival chondrosarcoma: Microsurgical 2-D video
Authors: Lopez-Gonzalez Miguel Angel , Eastin Timothy Marc , Ramanathan Dinesh , Minwoo Song , Choudhury Baishakhi 
Published: May 2020

Background:
Petroclival lesions pose a significant neurosurgical challenge due to involvement or close proximity to important neurovascular structures. Chondrosarcomas are rare lesions that can affect these areas.

Case Description:
A 24-year-old male with 3 months history of poor coordination, imbalance, left-sided face hypoesthesia, facial palsy House-Brackmann Grade 2, and 6th cranial nerve palsy with diplopia. Hearing was preserved. Preoperative images showed a 5.5 cm multilobulated enhancing extra-axial mass centered in the left petroclival region with extension into middle and posterior fossa causing severe (Stage 3) brainstem compression.[1] After a lengthy discussion of treatment options, the patient consented for the procedure. We performed a presigmoid retrolabyrinthine combined petrosal approach. We used cranial nerves monitoring (VII, VIII, IX, X, XI, XII), frameless stereotaxy, and a lumbar drain. Due to the tumor size and location (petroclival region with extension into the posterior and middle cranial fossa), we chose this approach to achieve a maximal safe resection of the tumor and preserve hearing. Alternative approaches of use are expanded middle fossa with transcavernous extension or expanded endonasal approach. The selected approach achieved wide exposure of the tumor which was highly vascular. The tumor was carefully dissected off the brainstem, cranial nerves (IV, V, VI, VII, VIII), and basilar artery trunk. A gross total resection was achieved (Multimedia 1). The patient did well after surgery and was extubated on postoperative day (POD) 1 and the lumbar drain removed on POD 5. Pathology reported low-grade chondrosarcoma (WHO grade I). At 3 months follow-up, the patient improved neurologically, including facial nerve weakness (House-Brackmann Grade 1) except for his left 6th cranial nerve palsy which mildly improved.

Conclusion:
Petroclival chondrosarcomas are rare tumors that are usually treated with surgical resection followed by stereotactic radiosurgery. The tumor size, location, and extension dictate approach selection. For lesions involving the petroclival region with extension into the middle fossa and posterior fossa, the combined petrosal approach is reasonable.
Engorged venous plexus mimicking adjacent segment disease: Case report and review of the literature
Authors: Hassan Omron , Lewis Courtney S. , Aradhyula Likitha , Hirshman Brian R. , Pham Martin H. 
Published: May 2020

Background:
An engorged venous plexus may mimic nerve compression from a herniated disk on the magnetic resonance (MR) studies as they both have similar signal intensities. During a laminectomy, if an engorged venous plexus is encountered instead of a disk herniation, there may be marked unanticipated bleeding.

Case Description:
A 58-year-old female who had a prior anterior lumbar interbody fusion later returned with recurrent radiculopathy. Adjacent segment disease from a spinal disk herniation was suspected based on the surgical history, physical examination, and imaging (MRI) findings. Rather than a disk, an engorged venous plexuses (EVP) was encountered intraoperatively.

Conclusion:
Here, we discussed our findings regarding a lumbar EVP rather than a herniated disk and reviewed the current literature. Although rare, a higher index of suspicion for these vascular malformations based on combined historical information and MRI studies should allow one to better detect and/or anticipate an EVP rather than a routine disk.
Primary pediatric cerebellar gliosarcoma
Authors: Bukhari Syed Sarmad , Junaid Muhammad , Afzal Ali , Kulsoom Anisa 
Published: May 2020

Background:
Primary gliosarcomas of the central nervous are rare and very few have been reported in the infratentorial compartment. Here, we describe such a lesion in a 12-year-old male.

Case Description:
A 12-year-old male presented with headache, ataxia, and vomiting. When Magnetic resonance studies documented a posterior fossa lesion, he underwent placement of a right ventriculoperitoneal shunt followed by a suboccipital craniectomy. The lesion proved to be a primary gliosarcoma. Unfortunately, it recurred 2 years later and required repeated resection.

Conclusion:
Here, we reviewed the rare case of a 12-year-old male requiring shunt placement and suboccipital craniectomy for a primary gliosarcoma that recurred 2 years later.
Parinaud syndrome as an unusual presentation of intracranial hypotension
Authors: Lyons Alexandra Rose , Olson Sarah Louise 
Published: May 2020

Background:
Vertical gaze palsy is a rare clinical manifestation of intracranial hypotension. The typical features of intracranial hypotension include a postural headache, dural enhancement, and low cerebrospinal fluid (CSF) opening pressure.

Case Description:
We describe a case of a shunt-dependent middle-aged female with aqueductal stenosis who developed recurrent presentations of upgaze palsy with postural headaches, confirmed low opening pressure, and slit ventricles on magnetic resonance imaging (MRI) due to shunt overdrainage. Her ophthalmoplegia and headaches improved following third ventriculostomy and with increasing the shunt opening pressure to prevent excess CSF drainage.

Conclusion:
Intracranial hypotension should be considered part of the differential diagnosis for patients presenting with an upgaze palsy.
