Abstract Primary neuroleptospirosis although rare but has been reported in the literature in the form of case reports and case series. However, there are no reports of autoimmune encephalitis triggered by leptospirosis in the literature, although four cases of acute disseminated encephalomyelitis, which is also considered to have autoimmune etiology have been reported. We are reporting an adolescent girl, who developed anti-N-methyl-d-aspartate receptor encephalitis after the resolution of systemic symptoms of leptospirosis. Her symptoms including neuropsychiatric and extrapyramidal features and sleep disturbances resolved completely after immunotherapy. As recently autoimmune encephalitis triggered by various infections are getting reported more frequently around the world, the clinicians need to consider this clinical possibility, even in patients with leptospirosis, who develop neurological symptoms while systemic clinical features are subsiding. Early recognition and timely administration of immunotherapy have the potential to completely reverse the neurological symptoms.

The Impact

AbstractSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus, is responsible for the outbreak of coronavirus disease 19 (COVID-19) and was first identified in Wuhan, China in December 2019. It is evident that the COVID-19 pandemic has become a challenging world issue. Although most COVID-19 patients primarily develop respiratory symptoms, an increasing number of neurological symptoms and manifestations associated with COVID-19 have been observed. In this narrative review, we elaborate on proposed neurotropic mechanisms and various neurological symptoms, manifestations, and complications of COVID-19 reported in the present literature. For this purpose, a review of all current published literature (studies, case reports, case series, reviews, editorials, and other articles) was conducted and neurological sequelae of COVID-19 were summarized. Essential and common neurological symptoms including gustatory and olfactory dysfunctions, myalgia, headache, altered mental status, confusion, delirium, and dizziness are presented separately in sections. Moreover, neurological manifestations and complications that are of great concern such as stroke, cerebral (sinus) venous thrombosis, seizures, meningoencephalitis, Guillain–Barré syndrome, Miller Fisher syndrome, acute myelitis, and posterior reversible encephalopathy syndrome (PRES) are also addressed systematically. Future studies that examine the impact of neurological symptoms and manifestations on the course of the disease are needed to further clarify and assess the link between neurological complications and the clinical outcome of patients with COVID-19. To limit long-term consequences, it is crucial that healthcare professionals can early detect possible neurological symptoms and are well versed in the increasingly common neurological manifestations and complications of COVID-19.

Nmda Receptor Encephalitis

Autoimmune encephalitis is an increasingly recognized cause of encephalitis. The majority of case series report patients residing in developed countries in the northern hemisphere. The epidemiologic features of autoimmune encephalitis in Latin America are still unclear. The aim of the study was to perform a review of the clinical presentation of autoimmune encephalitis in Latin America and compare to world literature. References were identified by an in-depth literature search and selected on the basis of relevance to the topic and authors' judgment. We selected clinical studies and case reports published from 2007 to July, 2020 including patients from Latin American countries. Of the 379 patients included, the majority were cases of anti-NMDA receptor encephalitis (93.14%), followed by anti-VGKC-complex encephalitis (N = 17; 4.48%), anti-GAD encephalitis (N = 9; 2.37%), anti-AMPA receptor encephalitis (N = 1; 0.26%), anti-GABA receptor encephalitis (N = 1; 0. 26%), anti-mGluR5 encephalitis (N = 1; 0. 26%), and anti-mGluR1 encephalitis (N = 1; 0. 26%). Reported cases of Anti-NMDA encephalitis in Latin-America had a very slight female predominance, lower prevalence of associated tumors and a lower incidence of extreme delta brush on electroencephalogram. Autoimmune encephalitis is possibly underdiagnosed in underdeveloped countries. Its outcome after treatment, however, appears to be similarly favorable in Latin American patients as has been reported in developed countries based on available case reports and case series. Regional specificities in the manifestation of autoimmune encephalitis could be related to epidemiologic factors, such as the presence of different triggers and different genetic and immunologic background, that need to be studied by future research.

Background: We reviewed the frequency, recognition, and management of postoperative hematomas (HT) (i.e. retropharyngeal [RFH], wound [WH], and/or spinal epidural hematomas [SEH]) following anterior cervical discectomy/fusion (ACDF), anterior corpectomy fusion (ACF), and/or anterior cervical spine surgery (ACSS). Methods: Postoperative cervical hematomas following ACDF, ACF, and ACSS ranged from 0.4% to 1.2% in a series of 11 studies involving a total of 44, 030 patients. These included; 4 single case reports, 2 small case series (6 and 30 cases), 4 larger series (758–2375 for a total of 6729 patients), an a large NSQUIP (National Surgical Quality Improvement Program ) Database involving 37,261 ACDF patients. Results: Risk factors contributing to postoperative cervical hematomas included; DISH (diffuse idiopathic skeletal hyperostosis), ossification of the posterior longitudinal ligament (OPLL), therpeutic heparin levels, longer operative times, multilevel surgery, ASA Scores of +/= 3, (American Society of Anesthesiologists), prone surgery, operative times > 4 hours, smoking, higher/lower body mass index (BMI), anemia, age >65, > medical comorbidities, and male gender. Notably, the use of drains did not prevent HT, and did not increase the infection, or reoperation rates. Conclusion: In our review of 11 studies focused on anterior cervical surgery, the incidence of postoperative hematomas ranged from 0.4 to 1.2%. Early recognition of these postoperative hemorrhages, and appropriate management (surgical/non-surgical) are critical to optimize recovery, and limit morbidity, and mortality.

Coronavirus (SARS-CoV-2) emerged in China in December 2019 and rapidly caused a global health pandemic. Current evidence seems to suggest a possible link with ecosystem disequilibrium and even air pollution. The primary manifestations affect respiratory and circulatory systems, but neurological features are also being reported through case reports and case series. We summarize neurological symptoms and complications associated with COVID-19. We have searched for original articles published in PubMed/Medline, PubMed Central and Google Scholar using the following keywords: “COVID-19”, “Coronavirus”, “pandemic”, “SARS-COV-2”, “neurology”, “neurological”, “complications” and “manifestations”. We found around 1000 publications addressing the issue of neurological conditions associated with COVID-19 infection. Amongst those, headache and dizziness are the most common reported symptoms followed by encephalopathy and delirium, while the most frequent complications are cerebrovascular accidents, Guillain–Barré syndrome, acute transverse myelitis, and acute encephalitis. Specific symptoms affecting the peripheral nervous system such as hyposmia and dysgeusia are the most common manifestations recorded in the selected studies. Interestingly, it was noted that these kinds of neurological symptoms might precede the typical features, such as fever and cough, in COVID patients. Neurological symptoms and complications associated with COVID-19 should be considered as a part of the clinical features of this novel global pandemic.

Hemodynamic Deterioration

Background: Pericardial Decompression Syndrome (PDS) is defined as paradoxical hemodynamic deterioration and/or pulmonary edema, commonly associated with ventricular dysfunction. This phenomenon was first described by Vandyke in 1983. PDS is a rare but formidable complication of pericardiocentesis which if not managed appropriately is fatal. PDS as an entity has dispersed literature; this review is to understand its epidemiology, presentation, and management. Methodology: Medline: Science Direct and Google Scholar databases were utilized to do a systemic literature search. PRISMA protocol was employed. Abstracts, case reports, case series and clinical studies were identified since 1983 to 2019. A total of 6508 articles were reviewed out of which 210 were short listed, after removal of duplicates 49 manuscripts were included in this review. For Statistical analysis, patient data was tabulated in SPSS version 20. Cases were divided into two categories surgical and percutaneous groups. T test was done for continuous variable and chi square test was done for categorical data was used for analysis. Results: A total of 42 full length case reports, 2 poster abstracts, 3 case series of 2 patients , 1 case series of 4 patient s and 1 case series of 5 patients were included in the study. A total of 59 cases were included in this manuscript. Our data had 45.8% (n=27) males and 54.2% (n=32) females. The mean age of patients was 48.04 ± 17 years. Pericardiocentesis was performed in 52.5% (n=31) cases, Pericardiostomy was performed in 45.8% (n=27). The most common identifiable cause pericardial effusion was found to be malignancy in 35.6% (n=21). 23 cases reported pre-procedural ejection fraction which ranged from 20%-75% with a mean of 55.8 ± 14.6%, while 26 cases reported post procedural ejection fraction which ranged from 10%-65% with a mean of 30% ± 15.1%. Data was further divided into two categories namely, pericardiocentesis and pericardiostomy. The outcome as death was significant in the pericardiostomy arm with a p-value of < 0.00. Use of inotropic agents for the treatment of PDS was more common in needle pericardiocentesis with a p-value of 0.04. Lastly, the computed recovery time did not yield any significance with a p-value of 0.275. Conclusion: Pericardial decompression syndrome is a rare condition with high mortality. Operators performing pericardial drainage should be aware of this complication following drainage of cardiac tamponade, since early recognition and expeditious supportive care are the only therapeutic modalities available for adequate management of this complication.

Percutaneous coronary intervention has become a fundamental diagnostic and treatment strategy in coronary artery disease. Much like any procedure, it is not without risk; in fact, a rare but life-threatening complication as a result of percutaneous coronary intervention is coronary artery perforations (CAP). The risk of CAPs correspondingly rises in relation to the difficulty of the procedure, location of lesion, and complexity of anatomy. It follows then that early recognition and instigation of an appropriate treatment strategy is key in reducing the mortality and morbidity associated with CAPs. The authors present eight case reports of varying difficulties, their analogous management, and a literature review of management approaches in treating CAPs in order to provide a review of management strategies and to highlight the importance of immediate recognition of a potentially fatal complication.

Coronary Syndrome

A 12-year-old male patient suffering from congenital glaucoma developed bradycardia, left ventricular failure, and hypotension after induction of anesthesia. Electrocardiography and echocardiography revealed a complete normalization of ECG and a complete spontaneous recovery in the cardiac function 72 hours from the beginning of the clinical manifestations, while cardiac Magnetic Resonance Imaging was performed, and coronary Computed Tomography scan revealed a myocardial bridge of a tract of the left anterior descendent coronary artery. Diagnosis of Kounis syndrome (KS) was made, a relatively novel, under-recognized clinical condition, defined as the manifestation of an acute coronary syndrome accompanied by mast cell activation and platelet aggregation involving interrelated and interacting inflammatory cells in the setting of allergic, hypersensitivity, anaphylactic or anaphylactoid insults. We described one of the first pediatric cases of KS related to anesthetic medications. In children, this syndrome has been only described in isolated case reports or small case series. Thus, it appears critical to report new cases of KS in children to increase the awareness of this disease in pediatric healthcare workers so as to enhance its early recognition and optimal therapeutic strategy. Furthermore, it appears of paramount importance the implementation of universal guidelines accepted by allergology and cardiology societies, in order to standardize the management of pediatric and adult patients with KS. Finally, a close collaboration between pediatric allergists and cardiologists seems fundamental for an optimal multidisciplinary patient care.

Background and Aim. ROHHADNET (rapid-onset obesity with hypoventilation, hypothalamic, autonomic dysregulation, neuroendocrine tumor) syndrome is a rare disease with grave outcome. Although early recognition is essential, prompt diagnosis may be challenging due to its extreme rarity. This study aimed to systematically review its clinical manifestation and to identify genetic causes. Materials and Methods. We firstly conducted a systematic review on ROHHAD/NET. Electronic databases were searched using related terms. We secondly performed whole exome sequencing (WES) and examined copy number variation (CNV) in two patients to identify genetic causes. Results. In total, 46 eligible studies including 158 patients were included. There were 36 case reports available for individual patient data (IPD; 48 patients, 23 ROHHAD, and 25 ROHHADNET) and 10 case series available for aggregate patient data (APD; 110 patients, 71 ROHHAD, and 39 ROHHADNET). The median age at onset calculated from IPD was 4 years. Gender information was available in 100 patients (40 from IPD and 60 from APD) in which 65 females and 35 males were showing female preponderance. Earliest manifestation was rapid obesity, followed by hypothalamic symptoms. Most common types of neuroendocrine tumors were ganglioneuromas. Patients frequently had dysnatremia and hyperprolactinemia. Two patients were available for WES. Rare variants were identified in PIK3R3, SPTBN5, and PCF11 in one patient and SRMS, ZNF83, and KMT2B in another patient, respectively. However, there was no surviving variant shared by the two patients after filtering. Conclusions. This study systematically reviewed the phenotype of ROHHAD/NET aiming to help early recognition and reducing morbidity. The link of variants identified in the present WES requires further investigation.

Background and Objective: The presence of an internal and often occult malignancy may be forewarned by various oral manifestations. Several of these findings are preferentially localized to the head and neck region, including the oral cavity. This places the dental practitioner in a unique position to detect these signs and symptoms of occult neoplastic involvement. Because they may be present before an established syndrome or cancer diagnosis, even representing the initial expression of disease in some cases, early recognition by a dentist may lead to timely diagnosis and management of these syndromes. Thus, the aim of this narrative review was literature search and gathering data of such syndromes. Materials and Methods: A Medline–PubMed search was conducted of the literature using the keywords “syndrome,” “dental management,” “Cowden’s syndrome,” “Peutz–Jeghers syndrome,” “malignant component,” “Gardner’s syndrome,” “Gorlin–Goltz syndrome,” and “McCune–Albright syndrome.” The search strategy was limited to human studies (case reports and case series), full-text English articles published from January 1, 2000, to mid-2019. Irrelevant articles or articles with inadequate information were omitted. Results: A total of 36 pieces of literature were reviewed, of which 13 were literature reviews, 15 case reports, 3 expert committee guides and updates, and 4 original research papers, and 1 was a book. Conclusion: These syndromes pose risk during dental practice, which necessitates extra awareness and caution to prevent potential complications. Although, the multidisciplinary approach in treating these cases is not well documented, any related information may be helpful in understanding the pathogenesis and the nature of these syndromes.
