Published: June 2021

In an effort to prevent the Covid-19 pandemic, schools are implementing online student learning methods. This government policy is in order to break the chain of spreading Covid-19. However, in practice, there are still many teachers in schools who are still confused about implementing the online learning system because the teachers are not good at technology, so the teacher only sends assignments without explaining the material. As a result, online learning becomes ineffective which has an impact on student learning outcomes. This study aims to determine the effectiveness of the tiktok-based online learning model. The method used in this research is phenomenology. The informants in this study were the parents of students who live in East Java. The conclusion of this study is that the Tik Tok application used as a learning medium has not been fully effective. Parents consider that the Tik Tok application used in their children's learning is mostly used for playing while learning hours are still in progress.

Meningioma as the host for metastatic breast cancer: A rare occurrence with important therapeutic impact
Authors: Hosseinzadeh Mohammad , Ketabchi Seyed Mehdi , Ahmadi Seyed Ali , Hendi Kasra , Alimohamadi Maysam 
Published: June 2021

Background:
Tumor-to-tumor metastasis is a rare condition. There are few reports of metastatic tumors within intracranial tumors, including meningiomas. Since some metastatic tumors have osteoblastic imaging pattern, it is not always easy to differentiate them from meningioma on preoperative studies.

Case Description:
A 60-year-old female referred to our center complaining about a progressive headache, nausea, and vomiting for the past month. She had a history of breast cancer treated with radical mastectomy (5 years ago) and adjuvant chemotherapy (until 1 year ago). Workups revealed a dural-based mass in the left temporobasal and midline subfrontal regions. Histopathological study showed breast cancer metastasis nests within the primary meningioma.

Conclusion:
As the diagnosis of metastatic nests inside a benign tumor, drastically alters postoperative adjuvant treatments, a high index of suspicion is needed evaluating tumors from patients with a history of systemic neoplasms.
Ganglioglioma of the cervicothoracic spinal cord in a patient with neurofibromatosis type 1: A case report
Authors: Cruz Thainá Zanon , Ferreira-Pinto Pedro Henrique Costa , Brito Ana Carolina Gonçalves , Ururahy Leandro , Sanchez Jefferson Trivino , Nigri Flavio 
Published: June 2021

Background:
Gangliogliomas are rare tumors of the central nervous system. They are usually located intracranially and rarely in the spinal cord. There is no clear correlation between this tumor and neurofibromatosis type 1 (NF1) with only four cases described. The aim of this article is to describe one more case and add data to the literature regarding this rare association.

Case Description:
An 8-year-old boy with NF1 presented progressive asymmetrical paraparesis (Grade 4 medical research council scale on the right leg and Grade 3 on the left leg). The cervicothoracic spinal magnetic resonance imaging demonstrated an intramedullary lesion from C4 to T4 vertebrae. The patient underwent a microsurgical resection. A partial resection was performed due to a drop in the motor evoked potential signal amplitude during dissection. Pathology report revealed a ganglioglioma (World Health Organization Grade I). Postoperatively, the patient evolved with worsening of the paraparesis. A few weeks later, he has improved his preoperative functional neurological state (better strength and gait). Adjuvant radiotherapy was not used. The patient is being followed up at the neurosurgery outpatient clinic.

Conclusion:
This is another case of spinal ganglioglioma associated with NF1. The tumor must be included in the differential diagnosis of patients with NF1 and spinal lesions. Complete microsurgical resection remains the standard treatment for spinal gangliogliomas, however, in this specific case, it was decided to leave a portion of the tumor to prevent neurological damage. The prognosis and treatment of this condition associated with NF1 remains to be determined.

Published: June 2021

Background:
Atlantoaxial dislocation is a rare injury following high-energy trauma. We report an undescribed complication of atlantoaxial dislocation.

Case Description:
A 75-year-old man presented with atlantoaxial dislocation and Jefferson C1 fracture after a high-energy trauma. Occipitoaxial stabilizations were performed the day after. A nasopharyngeal fistula was identified at day 5 causing a persistent epistaxis.

Conclusion:
Nasopharyngeal fistulization of C1 bony fragment is a rare complication of complex occipitocervical injury. Combined treatment with ENT surgeon should be considered.
Orbitozygomatic approach for large orbital cavernous hemangioma
Authors: de Melo Junior Jose Orlando , de Castro Marcelo Francisco Alcantara Ribeiro , Landeiro Jose Alberto 
Published: June 2021

Background:
Cavernous hemangiomas, more accurately defined as cavernous venous malformations, constitute the most common primary intraorbital tumors of adults comprising 4–9% of all tumors,[4] and the second most frequent cause of unilateral proptosis after thyroid-related orbitopathy.[3] Over 80% are located within the intraconal compartment, most commonly in the lateral aspect.[1] Surgical treatment for orbital cavernous hemangioma is generally required in symptomatic cases, optic nerve compression, and cosmetically disfiguring proptosis.[2] Transcranial approaches, the most familiar approaches for neurosurgeons, provide wide access to the entire superior and lateral orbit. They usually offer direct visualization, allowing for a safer dissection, while minimizing significant injury to the native neural and vascular anatomy of the orbit.[5] Although transcranial approaches continue to evolve, in many cases, they have been supplanted by endoscopic skull base approaches and modifications to deep lateral orbitotomy approaches.[5]

Case Description:
A 62-year-old male patient presented with slowly expanding left proptosis, which he had first noticed 3 years before presentation. He was already blind in his right eye due to a history of traumatic amaurosis in childhood. The left eye examination revealed severe proptosis with restricted eye movement in all directions and significant visual impairment (visual acuity of 20/300, expressed by Snellen test, with no improvement on correction). MRI of the orbit showed a large left superolateral intraconal cavernous hemangioma compressing and displacing the optic nerve, with the typical feature of slow gradual irregular enhancement with delayed washout on contrast-enhanced image. A one-piece modified orbitozygomatic approach was performed and a total en block resection was achieved. The bone flap was fixed with titanium miniplates and screws, the temporal muscle and the skin were closed in a standard fashion. The patient did not present any new deficit in the postoperative period. The patient had good functional and cosmetic outcomes with resolution of proptosis, restoration of eye movements, and improvement of visual acuity in the 3-month follow-up. Postoperative MRI showed total resection.

Conclusion:
The orbitozygomatic approach for large orbital cavernous hemangioma provides satisfactory orbital decompression and large working space, reduces traction, and increases visualization and freedom to dissect small vessels and nerves that may be tightly attached to the tumor pseudocapsule.
Perioperative dual antiplatelet therapy for patients undergoing spine surgery soon after drug eluting stent placement

Published: June 2021

Background:
Performing emergent spinal surgery within 6 months of percutaneous placement of drug-eluting coronary stent (DES) is complex. The risks of spinal bleeding in a “closed space” must be compared with the risks of stent thrombosis or major cardiac event from dual antiplatelet therapy (DAPT) interruption.

Methods:
Eighty relevant English language papers published in PubMed were reviewed in detail.

Results:
Variables considered regarding surgery in patients on DAPT for DES included: (1) surgical indications, (2) percutaneous cardiac intervention (PCI) type (balloon angioplasty vs. stenting), (3) stent type (drug-eluting vs. balloon mechanical stent), and (4) PCI to noncardiac surgery interval. The highest complication rate was observed within 6 weeks of stent placement, this corresponds to the endothelialization phase. Few studies document how to manage patients with critical spinal disease warranting operative intervention within 6 months of their PCI for DES placement.

Conclusion:
The treatment of patients requiring urgent or emergent spinal surgery within 6 months of undergoing a PCI for DES placement is challenging. As early interruption of DAPT may have catastrophic consequences, we hereby proposed a novel protocol involving stopping clopidogrel 5 days before and aspirin 3 days before spinal surgery, and bridging the interval with a reversible P2Y12 inhibitor until surgery. Moreover, postoperatively, aspirin could be started on postoperative day 1 and clopidogrel on day 2. Nevertheless, this treatment strategy may not be appropriate for all patients, and multidisciplinary approval of perioperative antiplatelet therapy management protocols is essential.
Trigeminal neuralgia secondary to onyx embolization of a right occipital arteriovenous malformation

Published: June 2021

Background:
Trigeminal neuralgia is a debilitating chronic condition characterized by severe recurrent hemifacial pain which is often caused by compression of the trigeminal nerve by an adjacent vessel loop. Microvascular decompression (MVD) surgery is an effective procedure that can lead to full symptomatic relief. Intracranial arteriovenous malformations (AVMs) are primarily congenital abnormalities that may be asymptomatic or manifest as seizures or focal neurologic deficits. They may cause intracranial bleeding and hence are promptly treated, often by endovascular embolization. This procedure is safe but may have a multitude of unpredictable complications.

Case Description:
A 33-year-old female presented with medically refractory trigeminal neuralgia secondary to Onyx embolization of a right occipital AVM 3 years prior. She underwent surgical exploration and MVD of the trigeminal nerve root which was found to be compressed by the previously embolized superior cerebellar artery. The procedure was successful and full symptomatic resolution was immediately achieved.

Conclusion:
Postprocedural trigeminal neuralgia is a procedural complication of Onyx endovascular embolization. It may be treated by MVD surgery regardless of the presence or absence of a compressive vascular loop on imaging.

Published: June 2021

Background:
Hypophysitis is described as a rare chronic inflammatory affection of the pituitary gland. However, to date, its pathogenesis has not been completely cleared up. Clinical features are polymorphic, including symptoms related to inflammatory compression and/or hypopituitarism. Laboratory tests determine hormone deficiencies orientating replacement therapy’s protocol. MRI of the hypothalamic-pituitary region is crucial in exhibiting major radiological signs such as pituitary homogeneous enlargement and gland stalk’s thickening. The etiological diagnosis is still challenging without affecting the management strategy. Corticosteroids have widely been used but a close follow-up without any treatment has also been approved.

Case Description:
In this report, seven patients with hypophysitis have been collected over a period of 6 years. The average age of our patients was 32.1 years ± 11.8 with a female predominance (71.4%). Panhypopituitarism was objective in 42.9% of cases, a combined deficiency of the hypothalamic-pituitary thyroid, adrenal and gonadal axes in 28.6% of cases. A central diabetes insipidus was noted in 42.9% of the patients. Idiopathic hypophysitis was the most common etiology. The use of long course corticosteroids was required in 28.6% when compressive signs were reported.

Conclusion:
Hypophysitis remains a rare disease with nonspecific clinical and radiological patterns. Autoimmune origin seems to be the most frequent etiology. No guidelines have been established for hypophysitis management and the evolution is still unpredictable.
Ectopic intraconal orbital meningioma – A rare case report
Authors: Sharma Anil Kumar , Gandhoke Charandeep Singh , Misra Somen , Ravi Ashik , Gupta Rakesh Kumar , Gupta Surendra Kumar 
Published: June 2021

Background:
Ectopic orbital meningiomas (OM) are a rare subset of OMs which are neither attached to the optic nerve sheath nor to the surrounding bone.

Case Description:
We report the case of a 65-year-old female who presented with a 1 year history of proptosis followed by visual loss and restricted right eye movements since 3 months. Radiology of the orbits was suggestive of intraorbital, intraconal, and heterogeneous contrast enhancing right eye lesion which was completely excised through supraorbital orbitotomy approach. Intraoperatively, the right optic nerve, though compressed, and displaced inferiorly, was free from the lesion. The final histopathological diagnosis was “Meningioma WHO Grade I.” At 3 months follow-up, patient’s vision in the right eye improved from perception of light positive to 6/12 and there was no evidence of recurrence.

Conclusion:
Rarity of ectopic OM, total surgical excision with an excellent postoperative visual outcome prompted us to report this case.

Masks are an important part of preventing Covid19 disease.The World Health Organization (WHO) have also recommended the community use masks when doing activities in public areas. There are many types of masks that are used to cover the nose and mouth. In general, there are about 3 types of masks that are commonly used by the public today, namely medical masks, N95 and cloth masks. This study aims to detect the type of mask used by the community. So that it can make easier for the government to apply discipline in COVID-19 health protocol. The detection method used in this study is a convolutional neural network (CNN). The first step is acquisition of knowledge, which first collects the types of masks on the market, followed by the representation of that knowledge before being modeled into a mathematical calculation formula, which will then be processed using the Convolutional Neural Network method. The system will be carried out by analyzing the recall value, its precision and accuracy.Testing process is carried out on an Android-based device and the mobilenetV2 framework. In this study, the accuracy value is 90% using ADAM Optimization and 80 % using Gradient descent optimization.

Published: June 2021

In Brazil, the National Health Plan (NHP) was the central instrument for public health planning from 2016 to 2019. In this paper, we show that there is a convergence between the Plan and the publication of scientific articles written by institutional researchers in the context of Neglected Tropical Diseases. The methodology used consisted of the following stages: identification of the universe of researchers, data collection, thematic characterization of Neglected Tropical Diseases in the Plan, organization of information, and production of indicators. In total, there were 2,719 researchers and 18,023 journal articles from 2015 to 2018. Of these, 2,541 articles, or 14.09%, were related to Neglected Tropical Diseases. Regarding the convergences, there was strong alignment with leishmaniasis, Chagas disease, dengue, leprosy, schistosomiasis, and Chikungunya fever. However, the coverage of topics by scientific publications was broader than that of the political instrument due to the inclusion of other themes: snake bites, helminthiasis and lymphatic filariasis.
