Cerebral venous sinus thrombosis (CVST) is a rare but critical cerebrovascular condition characterized by clot formation in cerebral veins or sinuses. We present a case of a 30-year-old male with CVST, an atypical presentation of right-sided weakness and sudden loss of consciousness. While CVST typically manifests as severe headaches and neurological deficits, our patient's unique symptoms pose diagnostic challenges. Advanced imaging techniques, including MRI with venography, played a pivotal role in confirming the diagnosis. Treatment involved anticoagulation therapy and resulted in a favorable outcome. This case highlights the importance of considering CVST in patients with unusual neurological symptoms and the crucial role of early diagnosis and intervention. Advances in diagnostic modalities and treatment options have significantly improved outcomes in CVST patients, emphasizing the need for timely recognition and management.

- Abstract
Acute proptosis is a very rare condition presenting to the emergency department. As there are very few case reports of patients with acute onset proptosis, it is important to report each new case. This case report is of a 38-year-old lady who presented to our emergency department with a headache for three days, altered sensorium for eight hours, and acute proptosis of the left eye for 40 minutes. She was diagnosed to have a venous hemorrhagic infarct in the left parietal-occipital-temporal region with thrombosis of the left transverse and sigmoid sinuses. To the best of our knowledge, there is no documented case report or study which featured acute proptosis as a clinical sign in a patient with venous hemorrhagic infarct or where acute proptosis was associated with thrombosis of a cerebral venous sinus other than cavernous sinus. This study shows that acute proptosis can be a presenting sign even in venous hemorrhagic infarct and acute proptosis can be associated with cerebral sinus venous thrombosis even without the involvement of cavernous sinus. So although rare, venous hemorrhagic infarct and cerebral venous sinus thrombosis irrespective of the venous sinus involved should be considered in any patient presenting to the emergency department with acute onset proptosis., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Ilyas et al.)

This study was conducted to comprehensively investigate the clinical features, brain imaging findings, and treatment outcomes of patients diagnosed with cerebral venous thrombosis.Materials and Methods: Conducted as a cross-sectional descriptive study, patients diagnosed with cerebral venous thrombosis were enrolled at Can Tho Central General Hospital between January 2021 and June 2022.Results: Notably, a substantial proportion of patients (83.4%) exhibited signs of brain damage, with intracranial hemorrhage (50%), brain infarction (30.9%), subarachnoid hemorrhage (16.6%), and hemorrhagic infarct (4.7%) being the predominant findings. Thrombosis primarily affected the superior sagittal sinus (85.7%), transverse sinus (52.4%), and sigmoid sinus (42.8%). All patients received anticoagulation treatment, resulting in a favorable recovery upon hospital discharge for the majority (90.5%), while a small percentage (9.5%) experienced critical illness or death.Conclusion: Our study on cerebral venous thrombosis found diverse clinical presentations, primarily headache. Intracranial hemorrhage was common, affecting superior sagittal, transverse, and sigmoid sinuses. Most patients achieved favorable recoveries with anticoagulation treatment, emphasizing early intervention’s importance.The plain language summary: Cerebral venous thrombosis (CVT) is a less common condition when compared to arterial thrombosis, which has received more research attention. However, CVT has not received the same level of focus and investigation. The study aimed to comprehensively examine the clinical features, brain imaging findings, and treatment outcomes of patients diagnosed with CVT. The findings revealed that patients with CVT commonly presented with symptoms such as headache, limb weakness, seizures, vomiting, and consciousness disorders. Neuroimaging showed significant brain damage, including intracranial hemorrhage and brain infarction. However, with appropriate anticoagulation treatment, the majority of patients achieved favorable recoveries. The study emphasizes the importance of early intervention and highlights the need for improved diagnostic accuracy and treatment strategies for CVT.Keywords: cerebral venous thrombosis, CVT, hemorrhagic infarct, superior sagittal sinus

15. New Findings from Pacific Institute of Medical Sciences in the Area of Tuberculosis Published (Granulomatosis with polyangiitis masquerading as disseminated tuberculosis in presence of bilateral lung cavities and hemorrhagic infarct).
- Abstract
A recent study conducted by the Pacific Institute of Medical Sciences in India has highlighted the importance of considering alternative diagnoses when patients present with lung cavities and constitutional symptoms, as these symptoms are commonly associated with pulmonary tuberculosis in India. The study focused on a 40-year-old female patient who was initially diagnosed with disseminated tuberculosis but did not respond to treatment. Further investigation revealed that she actually had granulomatosis with polyangiitis (GPA), a systemic pulmonary disease. The patient was successfully treated with a combination of medications, and the study emphasizes the need for prompt and accurate diagnosis in cases of pulmonary cavitations.

Stroke is amongst the leading causes of morbidity and mortality globally. Majority of strokes are ischemic and up to 1/3rd ischemic strokes have infective etiology. In this post-pandemic era, SARS-CoV-2 is an established infectious agent which can precipitate it by various mechanisms. Though post-vaccination incidence of COVID-19 has dropped drastically, still new cases get reported with typical or atypical presentations. Irrespective of causation, malignant cerebral edema in stroke necessitates salvage neurosurgery. Hereby authors present an interesting diagnostic chase in a young female who presented in altered sensorium, underwent emergency decompressive craniectomy and neurologically recovered over subsequent days. Despite being double vaccinated, she developed potentially fatal COVID-encephalitis, cerebral venous sinus thrombosis (CVST), ischemic infarcts and hemorrhagic transformation. Suprisingly, there were cross reacting antibodies against antigens of herpes simplex virus (HSV), leptospira and cytomegalovirus (CMV) yielding false positivity on serology screening test, which spoofed us while carrying out infectious disease work up of stroke.

Background: Cerebral venous sinus thrombosis (CVST) accounts for 10%–20% of strokes in young persons. In India, CVST accounts for around 30% of all strokes. The majority of CVSTs are caused by procoagulant circumstances, with pregnancy and early puerperium being well-established risk factors. The study aimed to look into the clinical profile, radiological characteristics, etiological variables, and outcome of CVST in venous stroke patients admitted to a tertiary care facility. Methods: We included individuals between the ages of 18 and 75 years who had a cerebral venous thrombosis (CVT) diagnosis confirmed by magnetic resonance imaging (MRI) + magnetic resonance venography computed tomography (CT) plus CT venography. The research included all individuals suspected of having CVST with or without particular neurological deficits and a confirmed imaging diagnosis. Patients were removed in situations of ambiguous neuroimaging, arterial strokes, space-occupying lesions, metabolic encephalopathy, and patient reluctance to participate. Results: This study included 82 patients, 21 (25.6%) males and 61 (74.4%) of whom were females. The most common presenting symptom was headache (79.2%), followed by vomiting (54.8%) and abnormal sensorium (35.3%). In this study, 34/82 (41.4%) patients had evident clinical triggers and were classified as induced CVT. Para infectious disease was recognized as a risk factor for CVT in 13/34 (38.2%) patients. A prothrombotic conditions could be established in 48 (58.5%) of these patients. Conclusion: CVST is a treatable and reversible cause of stroke in adolescents. The clinical presentation varies greatly, and symptoms may appear gradually over weeks or months. Although it is still an uncommon cause of headache and stroke, MRI has allowed for early detection.

Purpose: A prospective, observational study was done at the country leading tertiary care hospital to evaluate etiologies, clinical features, diagnosis, and prognosis of cerebral venous sinus thrombosis (CVST) in the Pakistani population. Methods: 34 patients with clinical and MRI features suggestive of CVST were evaluated. Modified Rankin Score (mRS) was assessed of all patients at presentation. Results: The mean age of presentation was 30.69 years with female predominance (n = 28). Headache was most common presenting symptoms (97%, n = 33) followed by seizure (59%, n = 20), hemiparesis (56%; n = 19), altered sensorium (47%; n = 16), vomiting (21%; n-7) and cranial nerve involvement (18%; n = 6). 72% of patients (n = 23) had thrombosis of superior sagittal sinus, 53% of patients (n = 17) had thrombosis of the transverse sinus, 25% patients (n = 8) of patients had sigmoid sinus thrombosis, 16 % patients (n = 8) had straight sinus thrombosis. The most common cause for provoked CVST was found to be pregnancy/puerperium in 53% (n = 18 patients), followed by previous CVST/DVT in 12% (n = 4), and then OCP and parainfectious causes which were 3% (n = 1) for each and elevated factor VIII and protein deficiency were found in 7 patients. MRS between 3 and 5 was assessed in most patients on presentation (n = 23). Conclusion: CVST is an under-recognized cause of stroke in the young population, especially in the puerperium period. Clinical presentation is highly variable, and correction with magnetic resonance imaging with venography is the current diagnostic modality of choice. Aggressive management with anticoagulants is safe with excellent clinical outcomes.

Background: Seizures are a common complication of cerebral venous thrombosis. In this study, we intended to define clinical and neuroradiological factors associated with early and late seizures and predictors for seizure recurrence. Methods: The database of our high-volume tertiary stroke center was screened for patients diagnosed with cerebral venous thrombosis between April 2006 and July 2021. Demographics, clinical, imaging, and instrumental data were collected. Results: Out of a total of 80 patients, 30 had seizures, either within the first week after onset (22 patients) or after (8 patients). Speech impairment and intracerebral bleeding were statistically associated with seizures in univariate analysis, but in a logistic regression model, only brain damage with hemorrhagic infarct and/or presence of brain hematoma [OR 6.051; 95% CI 1.881–19.468] (p = 0.003) were predicting factors for seizures. Late seizures were significantly more frequent in younger age [OR 0.864; 95% CI 0.763–0.978] (p = 0.020). Early seizures resulted as protective factors for recurrence; an altered state of consciousness at baseline and late seizures resulted as predictive factors for relapses (0.0% vs. 81.0%, p = 0.005, and 100.0% vs. 19.0%, p < 0.005, respectively). Conclusions: Our study confirms brain bleeding as the strongest risk factor for seizures after cerebral venous thrombosis. Recurrence is unusual after early seizures, while the presence of late seizures seems to raise the risk of recurrence.

Posthemorrhagic ventricular dilatation (PHVD) is a major complication of intraventricular hemorrhage (IVH); it is associated with high risks of cerebral palsy and cognitive deficits compared with infants without PHVD. This study aims to explore the early perinatal risk factors-associated with the risk of progressive PHVD. Neonates ≤29 weeks gestational age (GA) with Grade II-III IVH and periventricular hemorrhagic infarct (PVHI) between 2015 and 2021 were retrospectively reviewed. All cranial ultrasounds done within 14 days postnatal age (PNA) were assessed for grade of IVH, anterior horn width (AHW), ventricular index (VI), and thalamo-occipital index (TOD). The outcome was defined as death of any cause or VI and/or AHW and/or TOD ≥ moderate-risk zone based on an ultrasound done beyond two weeks PNA. A total of 146 infants with a mean GA of 26 ± 1.8 weeks, birth weight 900 ± 234 g were included, 46% were females. The primary outcome occurred in 56 (39%) infants; among them 17 (30%) and 11 (20%) needed ventricular reservoir and shunt insertion, respectively. The risk factors present within 14 days PNA that significantly increased the odds of developing PHVD were hemodynamically significant patent ductus arteriosus (odds ratio [OR] 6.1, 95% confidence interval [CI] 1.9 to 22), culture-proven sepsis (OR 5.4, 95% CI 1.8 to 18), Grade III IVH (OR 4.6, 95% CI 1.1 to 22), PVHI (OR 3.0, 95% CI 0.9 to 10), and VI (OR 2.1, 95% CI 1.6 to 2.9). Clinical predictors such as significant ductus arteriosus and bacterial septicemia, along with risk levels of AHW and VI measured with early cranial ultrasounds, are potential predictors of subsequent onset of PHVD.

Context.--: Extracorporeal membrane oxygenation (ECMO) is increasingly used in the treatment of respiratory and cardiac failure, but data describing lung histopathology in ECMO recipients are limited. Objective.--: To examine pulmonary histopathologic findings in patients who underwent venovenous (VV) ECMO for pulmonary reasons or venoarterial (VA) ECMO for cardiac indications shortly before death, and to determine if the pulmonary changes provided insights into therapy that may prevent complications and improve outcome. Design.--: We conducted a retrospective study of lung autopsies, from VV and VA ECMO recipients and patients with acute respiratory distress syndrome (ARDS) and non-ECMO treatment, between 2008 and 2020 in Silesia Center for Heart Diseases in Zabrze, Poland. Results.--: Among 83 ECMO patients (42-64 years; men, 57 [68.7%]), the most common histopathologic findings were bronchopneumonia (44 [53.0%]), interstitial edema (40 [48.2%]), diffuse alveolar damage (DAD; 32 [38.6%]), hemorrhagic infarct (28 [33.7%]), and pulmonary hemorrhage (25 [30.1%]). DAD was associated with longer ECMO treatment and longer hospital stay. The use of VV ECMO was a predictor of DAD in patients with ARDS and undergoing ECMO, but it also occurred in 21 of 65 patients (32.3%) in the VA ECMO group, even though VA ECMO was used for heart failure. Conclusions.--: Although DAD was significantly more common in lung autopsies of VV ECMO patients, one-third of VA ECMO patients had histopathologic changes characteristic of ARDS. The presence of DAD in lung autopsies of patients treated with VA ECMO indicates that in these patients, protective lung ventilation should be considered. [ABSTRACT FROM AUTHOR]

Recently, weeks after the COVID-19 prevalence, there were reports of brain involvement and neurologic presentations in the COVID-19. We present five cases of COVID-19 and cerebrovascular events. A 34-year-old woman with IVH and ischemic stroke. A 60-year-old man with multiple small hemorrhagic foci and mild IVH in the occipital horn. A 63-year-old woman with large left parietooccipital intracerebral hemorrhage (ICH) and IVH. A 56-year-old man with left hemispheric and midbrain ICH, lateral ventricular IVH, and hydrocephalus. A 85-year-old woman with right parietal hemorrhagic infarct. The coagulation profile was normal in all of them. The chest CT scan showed the typical ground-glass appearance of COVID-19. Recently, there were reports of brain involvement and neurologic presentations in the COVID-19. These reports and the present study necessitate the aimed and designed studies with emphasis on neurologic presentations in COVID-19 patients to illustrate the exact effects of coronavirus-2 on the central nervous system.

Takayasu arteritis is a well-known yet rare form of large vessel vasculitis. Takayasu arteritis affects mainly women, and is most commonly seen in Japan, South East Asia, India, and Mexico, where it usually presents in the 2
nd or 3rd decade of life. It is seen usually as pulseless disorder often with bruit at the stenosed arteries. Manifestations range from asymptomatic disease, to catastrophic strokes. Angiography remains the gold standard for diagnosis. Approximately half of those patients treated with steroids will respond, and half of the remaining patients respond to methotrexate; mycophenolatemofetil may be useful. Fertility is not adversely affected and pregnancy does not appear to exacerbate the disease, although management of hypertension is essential. We herewith report a rare case of an11 year old girl, who presented with left-sided hemiparesis, dysarthria, left UMN facial palsy, feeble pulses on right side, high Blood Pressure recordings and positive anticardiolipin antibodies. Imaging studies revealed Occluded right Common carotid artery, occluded right subclavian artery and stenotic right renal artery and MRI showed Acute Infarcts in Right Basal Ganglia and Right High Parietal Region, Hemorrhagic infarct in right MCA subcortical area.The diagnosis of Takayasu arteritis with recent cerebrovascular accident (left hemiparesis) with hypertension was made and the patient was started on steroids, anti-platelets, anti-hypertensives and physiotherapy.

- Abstract
Background: Seizures are a common complication of cerebral venous thrombosis. In this study, we intended to define clinical and neuroradiological factors associated with early and late seizures and predictors for seizure recurrence. Methods: The database of our high-volume tertiary stroke center was screened for patients diagnosed with cerebral venous thrombosis between April 2006 and July 2021. Demographics, clinical, imaging, and instrumental data were collected. Results: Out of a total of 80 patients, 30 had seizures, either within the first week after onset (22 patients) or after (8 patients). Speech impairment and intracerebral bleeding were statistically associated with seizures in univariate analysis, but in a logistic regression model, only brain damage with hemorrhagic infarct and/or presence of brain hematoma [OR 6.051; 95% CI 1.881-19.468] (p = 0.003) were predicting factors for seizures. Late seizures were significantly more frequent in younger age [OR 0.864; 95% CI 0.763-0.978] (p = 0.020). Early seizures resulted as protective factors for recurrence; an altered state of consciousness at baseline and late seizures resulted as predictive factors for relapses (0.0% vs. 81.0%, p = 0.005, and 100.0% vs. 19.0%, p < 0.005, respectively). Conclusions: Our study confirms brain bleeding as the strongest risk factor for seizures after cerebral venous thrombosis. Recurrence is unusual after early seizures, while the presence of late seizures seems to raise the risk of recurrence.

Venous hemorrhagic infarct due to cerebral venous sinus thrombosis (CVST) is associated with poor prognosis. A 30-year-old woman was brought to the emergency room with an episode of generalized tonic–clonic seizure, diagnosed with CVST involving superior sagittal sinus and right transverse sinus, and referred to psychiatry in view of symptoms of depression. Mental state examination revealed poor eye contact, decreased personal hygiene, hopelessness, and worthlessness in thought content with a sad mood and affect. A diagnosis of organic depressive disorder was made and managed with sertraline 50 mg/day. Timely diagnosis along with methodical therapeutic management of CVST reduces mortality and morbidity. This case report highlights the importance of being familiar with varied presentations and neuropsychiatric manifestations of CVST. [ABSTRACT FROM AUTHOR]

Objective: To develop and validate a model based on the radiomics features of the infarct areas on non-contrast-enhanced CT to predict hemorrhagic transformation (HT) in acute ischemic stroke. Materials and methods: A total of 118 patients diagnosed with acute ischemic stroke in two centers from January 2019 to February 2022 were included. The radiomics features of infarcted areas on non-contrast-enhanced CT were extracted using 3D-Slicer. A univariate analysis and the least absolute shrinkage and selection operator (LASSO) were used to select features, and the radiomics score (Rad-score) was then constructed. The predictive model of HT was constructed by analyzing the Rad-score and clinical and imaging features in the training cohort, and it was verified in the validation cohort. The model was evaluated with the receiver operating characteristic curve, calibration curve and decision curve, and the prediction performance of the model in different scenarios was further discussed hierarchically. Results: Of the 118 patients, 52 developed HT, including 21 cases of hemorrhagic infarct (HI) and 31 cases of parenchymal hematoma (PH). The Rad-score was constructed from five radiomics features and was the only independent predictor for HT. The predictive model was constructed from the Rad-score. The area under the curve (AUCs) of the model for predicting HT in the training and validation cohorts were 0.845 and 0.750, respectively. Calibration curve and decision curve analyses showed that the model performed well. Further analysis found that the model predicted HT for different infarct sizes or treatment methods in the training and validation cohorts with 78.3 and 71.4% accuracy, respectively. For all samples, the model predicted an AUC of 0.754 for HT in patients within 4.5 h since stroke onset, and predicted an AUC of 0.648 for PH. Conclusion: This model, which was based on CT radiomics features, could help to predict HT in the setting of acute ischemic stroke for any infarct size and provide guiding suggestions for clinical treatment and prognosis evaluation.

Herniation of the temporal lobe uncus typically leads to the compression of the ipsilateral oculomotor nerve, resulting in ipsilateral mydriasis, as well as compression of the ipsilateral posterior cerebral artery, leading to infarction in the posterior inferior temporal lobe and medial occipital cortex. In this report, we present the case of a 45‐year‐old man with a large left subdural hematoma. At autopsy, we observed left cingulate and uncal herniations, along with the characteristic lesions of Kernohan notch phenomenon due to compression of the contralateral cerebral peduncle. Additionally, a hemorrhagic infarct was identified in the right cerebellar hemisphere in the distribution of the superior cerebellar artery (SCA). This case provides the first autopsy report of uncal herniation with contralateral SCA infarct, an extremely rare condition. Importantly, this vascular complication may often go unnoticed in patients with Kernohan notch phenomenon although it may carry a grave clinical prognosis. [ABSTRACT FROM AUTHOR]

- Abstract
Cerebral venous sinus thromboses (CVSTs) are rare complications of neurosurgical interventions and their management remains controversial as most of cases appear clinically silent. Here, we analyzed our institutional series of patients with CVSTs evaluating clinical and neuroradiological characteristics, risk factors, and outcome. From the analysis of our institutional PACS, we collected a total of 59 patients showing postoperative CVSTs after supratentorial or infratentorial craniotomies. For every patient, we collected demographics and relevant clinical and laboratory data. Details on thrombosis trend were retrieved and compared along the serial radiological assessment. A supratentorial craniotomy was performed in 57.6% of cases, an infratentorial in 37.3%, while the remaining were a single cases of trans-sphenoidal and neck surgery (1.7%, respectively). A sinus infiltration was present in almost a quarter of patients, and in 52.5% of cases the thrombosed sinus was exposed during the craniotomy. Radiological signs of CVST were evident in 32.2% of patients, but only 8.5% of them developed a hemorrhagic infarct. CVST-related symptoms were complained by 13 patients (22%), but these were minor symptoms in about 90%, and only 10% experienced hemiparesis or impaired consciousness. The majority of patients (78%) remained completely asymptomatic along the follow-up. Risk factors for symptoms occurrence were interruption of preoperative anticoagulants, infratentorial sinuses involvement and evidence of vasogenic edema and venous infarction. Overall, a good outcome defined mRS 0–2 was observed in about 88% of patients at follow-up. CVST is a complication of surgical approaches in proximity of dural venous sinuses. CVST usually does not show progression and courses uneventfully in the vast majority of cases. The systematic use of post-operative anticoagulants seems to not significantly influence its clinical and radiological outcome. [ABSTRACT FROM AUTHOR]

Background Mobile stroke units (MSUs) performance dependability and diagnostic yield of 16-slice, ultrafast CT with auto-injection angiography (CTA) of the aortic arch/neck/circle of Willis has not been previously reported. Methods We performed a prospective observational study of the first-of-its kind MSU equipped with high resolution, 16-slice CT with multiphasic CTA. Field CT/CTA was performed on all suspected stroke patients regardless of symptom severity or resolution. Performance dependability, efficiency and diagnostic yield over 365 days was quantified. Results 1031 MSU emergency activations occurred; of these, 629 (61%) were disregarded with unrelated diagnoses, and 402 patients transported: 245 (61%) ischemic or hemorrhagic stroke, 17 (4%) transient ischemic attack, 140 (35%) other neurologic emergencies. Total time from non-contrast CT/CTA start to images ready for viewing was 4.0 (IQR 3.5-4.5) min. Hemorrhagic stroke totaled 24 (10%): aneurysmal subarachnoid hemorrhage 3, hemorrhagic infarct 1, and 20 intraparenchymal hemorrhages (median intracerebral hemorrhage score was 2 (IQR 1-3), 4 (20%) spot sign positive). In 221 patients with ischemic stroke, 73 (33%) received alteplase with 31.5% treated within 60 min of onset. CTA revealed large vessel occlusion in 66 patients (30%) of which 9 (14%) were extracranial; 27 (41%) underwent thrombectomy with onset to puncture time averaging 141±90 min (median 112 (IQR 90-139) min) with full emergency department (ED) bypass. No imaging needed to be repeated for image quality; all patients were triaged correctly with no inter-hospital transfer required. Conclusions MSU use of advanced imaging including multiphasic head/neck CTA is feasible, offers high LVO yield and enables full ED bypass. [ABSTRACT FROM AUTHOR]

Introduction: Dengue counts among the most common arboviral illnesses, representing the fastest spreading tropical disease in the world. It is considered the second leading cause of acute febrile disease in travelers. Four different serotypes (DENV-1,-2,-3, and-4) cause dengue fever, with various infectious outcomes (asymptomatic to severe hemorrhagic fever). Dengue is prevalent in 128 countries, and more than 2.5 billion individuals are in danger each year of contracting dengue virus worldwide. Material & Methods: This is prospective study conducted at Department of Radio diagnosis, Kalinga Institute of Medical Sciences from November 2016 to April 2017 among 48 serologically proven dengue patients presenting with neurological symptoms and undergoing brain MRI over a period of 6-months were included. The diagnosis of dengue encephalopathy or encephalitis was established by presence of signs/symptoms of acute encephalitic syndrome with the presence of IgM antibody against dengue antibody in the serum and/or presence of dengue antigen (NS1) in serum. Any patients found to have positive serological test for malaria, leptospirosis, scrub typhus, Chikungunya, JE virus, and Herpes simplex virus (HSV) encephalitis were excluded from the study. Results: A total of 48 patients (29 men, 19 women; mean age of 29.84 years and age range of 2-70 years) were included in this study. Twelve patients (25%) were in the pediatric age group (<18 years of age) whereas the rest were in the adult age group. Of 48 cases, 15 cases were found to have no significant abnormality on MRI. Varying degrees of abnormality were found in rest of the 33 patients. The imaging findings are described based on a pattern recognition approach. Conclusion: MRI is an important tool for demonstrating the degree of brain involvement in dengue infection. Although the findings are not entirely unique to dengue, it can help to narrow down the list of differential diagnosis particularly when coupled with serological tests and CSF analysis. A pattern-based approach to evaluating the brain MRI in combination with patient's clinical details in the setting of dengue can help the radiologist to identify the definitive underlying pathologic process. This is of particular significance in differentiating between dengue encephalitis and post-dengue ADEM because of their different treatment strategies. [ABSTRACT FROM AUTHOR]

Background: Bartonella species are fastidious, intracellular bacteria responsible for an expanding array of human pathologies. Most are considered to be transmitted by direct inoculation with infected bodily fluids from a mammalian reservoir species or vector-transmitted through a variety of arthropod species and their excrement. However, there are mounting reports of infection in the absence of documented animal or vector contact. A variety of Bartonella species have been documented in conditions affecting both the peripheral and central nervous systems. More common conditions, including neuroretinitis, are often associated with Bartonella henselae. However, Bartonella quintana, the agent of trench fever, as well as emerging pathogens related to rodent reservoir species, B. grahamii and B. elizabethae, have also been documented. Encephalitis and encephalopathy, also most often associated with B. henselae, have been reported with B. quintana, B. washoensis (ground squirrels) and B. vinsonii subsp. vinsonii (voles) infections. Bartonella infections have also been associated with peripheral neuropathies, such as cranial nerve paresis and neuropathic pain, including infection with less commonly encountered species such as Bartonella koehlerae. Recently, molecular diagnostic testing revealed that DNA from Bartonella spp. was found to be more prevalent in blood of patients with neuropsychiatric disorders such as schizophrenia and psychoses compared to healthy controls. Methods: A systematic literature search was conducted on PubMed, Google Scholar and Web of Science. Search terms included Bartonella and specific neurological conditions and focused on peer-reviewed case reports published after 2012 pursuant to a prior review, with limited exceptions for conditions not previously covered. Published diagnostic testing, serology, molecular testing or pathology, were necessary for inclusion, except for one case which had clinical and epidemiological evidence consistent with diagnosis along with follow-up. Results: Neurobartonelloses included neuralgic amyotrophy, complex regional pain syndrome, chronic inflammatory demyelinating polyneuropathy, cranial nerve paralysis, Guillain-Barré syndrome, peripheral vasculitic polyneuropathy, acute transverse myelopathy, neuroretinitis, encephalitis/encephalopathy, cerebral vasculitis/aneurysm and neuropsychiatric conditions. Conclusions: The breadth of reported symptoms and clinical syndromes associated with an increasing number of Bartonella species continues to expand. Increased clinical awareness of this important zoonotic pathogen is necessary to advance One Health among the medical and veterinary communities. [ABSTRACT FROM AUTHOR]

Background: Surgery for adnexal mass does occur in pregnant women and therefore the choice of surgery during pregnancy needs to be carefully considered and studied. This study aimed to evaluate the safety and feasibility of Laparo-endoscopic Single-site Surgery (LESS) for adnexal mass during pregnancy and investigate the perioperative condition, pregnancy complications, and obstetric outcomes of operative women during pregnancy. Methods: This study retrospectively collected medical records and surgery videos of 20 pregnant women who underwent LESS for adnexal mass between November 2019 and January 2022. Baseline characteristics, operative-related variables, and pregnancy outcomes were followed up. Results: LESS for adnexal mass was successfully performed in 20 pregnant women, with very satisfactory surgery outcomes reported in all cases. The average gestational age at operation was 15
+2 weeks (range, 5+1 - 25+4 weeks). The median operative time was 80.8 min (range, 40 -185 min) and the average operative bleeding was 28.0 ml (range, 10–50 ml). The average VAS of 24 h postoperatively was 1 (range, 0–2), and the average length of hospital stay was 5.15 days (range, 3–7 days). All these women delivered a healthy newborn at full term except 1 woman induced abortion for her own reasons at 16+5 weeks gestational age (GA). The average GA of delivery was 39+1 weeks (range, 37–40+1 weeks), the average birth weight was 3228.95 g (range, 2740–3930 g), and the average Apgar score at 5 min was 9.95 (range, 9–10). Conclusions: LESS for adnexal mass is safe and feasible for pregnant women. [ABSTRACT FROM AUTHOR]- Published

Background: In recent years, cases of dystextia (texting disabilities) and dystypia (typing disabilities) have been reported. However, reports describing isolated dystextia without aphasia or other cognitive impairments are rare, and the detailed pathophysiology is not fully understood. Most Japanese people use the alphabetical spelling system (Romaji) for texting and typing. Herein, we report the case of a man with isolated dystextia and dystypia resulting from Romaji conversion difficulties. Case presentation: A 48-year-old, right-handed Japanese man developed texting and typing difficulties. The standard neuropsychological tests showed no signs of aphasia or other cognitive impairments, except for slight executive dysfunction. Thus, isolated dystextia and dystypia were diagnosed. Furthermore, the patient experienced Romaji conversion difficulties. Magnetic resonance imaging revealed a subcortical infarction in the left cerebral hemisphere. Single photon emission tomography revealed hypoperfusion, including in the left dorsolateral frontal cortex. Conclusions: The left dorsolateral frontal cortex may be related to Romaji conversion in Japanese individuals. Therefore, diaschisis of the left dorsolateral frontal cortex due to subcortical lesions may have impaired Romaji conversion, leading to dystextia and dystypia, in this patient.

Background Subarachnoid hyperdensities after mechanical thrombectomy (MT) are a common finding. However, it is often regarded as clinically insignificant. Objective With this single-center investigation, to identify the prevalence of subarachnoid hyperdensities following MT, associated predictors, and the impact on the clinical outcome of the patients. Methods 383 patients from the stroke registry were analyzed for the presence of subarachnoid hyperdensities on flat detector CT (FDCT) directly after the completion of MT, and on follow-up dual-energy CT, then classified according to a visual grading scale. 178 patients were included with anterior circulation occlusions. Regression analysis was performed to identify significant predictors, and Kruskal-Wallis analysis and X² test were performed to test the variables among the different groups. The primary outcome was the modified Rankin Scale (mRS) score at 90 days and was analyzed with the Wilcoxon-Mann-Whitney rank-sum test. Results The prevalence of subarachnoid hyperdensities on FDCT was (66/178, 37.1%) with patients experiencing a significant unfavorable outcome (P=0.035). Significantly fewer patients with subarachnoid hyperdensities achieved a mRS score of ≤3 at 90 days 25/66 (37.9%) vs 60/1 12 (53.6%), P=0.043). In addition, mortality was significantly higher in the subarachnoid hyperdensities group (34.8% vs 19.6%, P=0.024). Distal occlusions and a higher number of device passes were significantly associated with subarachnoid hyperdensities (P=0.026) and (P=0.001), respectively. Patients who received intravenous tissue plasminogen activator had significantly fewer subarachnoid hyperdensities (P=0.029). Conclusions Postinterventional subarachnoid hyperdensities are a frequent finding after MT and are associated with neurological decline and worse functional outcome. They are more common with distal occlusions and multiple device passes. [ABSTRACT FROM AUTHOR]

The World Health Organization has declared "with great hope" an end to COVID-19 as a public health emergency. The vaccination drive that started in December 2020 played a crucial role in controlling the pandemic. However, the pace at which COVID-19 vaccines were developed and deployed for general population use led to vaccine hesitancy, largely owing to concerns regarding the safety and efficacy of the vaccines. Radiology has been instrumental in demonstrating the extent of pulmonary involvement and identification of the complications of COVID-19, and the same holds true for vaccine-related complications. This review summarizes the existing body of radiological literature regarding the efficacy, adverse events, and imaging pitfalls that accompany the global rollout of various COVID-19 vaccines.

Background: In the state of Kentucky, many status asthmaticus (SA) patients require care in the Pediatric Intensive Care Unit (PICU) and a fraction of these patients may receive "rescue therapies" with inhaled volatile anesthetics (IVA) and/or Extracorporeal Membrane Oxygenation (ECMO). We present a series of such patients with the objective of comparing the clinical parameters of individual patients who received inhaled volatile anesthesia and subsequently the need for ECMO. Methods: Children between 2 and 18 years of age admitted to our PICU from January 2014 to July 2020 with SA were reviewed and categorized as 1) patients who received IVA alone, 2) patients who received IVA and then subsequently ECMO, and 3) patients on ECMO alone. Results: A total of 1772 children with SA episodes were identified with a mortality of 13 patients. Seven children with SA were identified who received either IVA, ECMO, or both. One patient received only IVA, 5 received both IVA and ECMO and one received only ECMO. All received standard asthma therapies of steroids, albuterol, magnesium sulphate, and aminophylline prior to escalation. Six out of seven refractory SA received IVA, and five (83%) of those were subsequently escalated to ECMO. There was an improvement in mean pH after cannulation compared to IVA. pCO2 levels had no improvement after IVA administration but decreased by an average of 20 points after ECMO. Patients peak inspiratory pressures decreased within the 1st 24 h of ECMO cannulation from a mean of 30 to 18. There were no other complications related to ECMO placement. Conclusion: While we cannot decisively draw any conclusions from our study due to the small sample, it was noted that there was no clear advantage of using IVA prior to ECMO in our patients. Most patients who received IVA were escalated to ECMO indicating that early ECMO cannulation may be beneficial. Given the high cost and potential complications of both, there is a need for the development of well-defined guidelines for severe SA management in the PICU. [ABSTRACT FROM AUTHOR]

A recent study conducted at the Silesian Centre for Heart Diseases in Zabrze, Poland, examined the lung histopathologic findings in patients who underwent extracorporeal membrane oxygenation (ECMO) treatment for respiratory and cardiac failure. The study found that the most common histopathologic findings in ECMO patients were bronchopneumonia, interstitial edema, diffuse alveolar damage (DAD), hemorrhagic infarct, and pulmonary hemorrhage. DAD was associated with longer ECMO treatment and hospital stay. The study suggests that protective lung ventilation should be considered in patients treated with venoarterial (VA) ECMO, as one-third of VA ECMO patients had histopathologic changes characteristic of acute respiratory distress syndrome (ARDS).
