Chest Pain as a Manifestation of Intracranial Hypotension: Report of Four Cases.

BACKGROUND: Chest pain has not been recognized as a manifestation of intracranial hypotension secondary to cerebrospinal fluid leakage. CASE REPORT: We report on 4 patients with intracranial hypotension diagnosed by the pattern of headaches, temporal proximity to dural puncture, magnetic resonance imaging findings, and resolution of symptoms after epidural blood patch who presented with chest pain. The chest pain was episodic, located in the sternal and interscapular region for the first 3 patients, with no radiation to any other region and no clear relationship to exertion. The fourth patient had episodic chest pain located in the subclavicular and suprascapular region. Two patients reported dyspnea with chest pain. Underlying coronary artery ischemia was excluded using a combination of the electrocardiogram and cardiac enzyme assays. The pain resolved after epidural blood patch treatment. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Clinicians should be aware of chest pain that can be seen with intracranial hypotension and cerebrospinal leakage to ensure appropriate diagnostic tests and treatment.

Mechanical thrombectomy with intra-arterial thrombolysis versus mechanical thrombectomy alone in patients with acute ischemic stroke: A systematic review and meta-analysis.

BACKGROUND: There is conflicting evidence as to whether intra-arterial thrombolysis (IAT) adds benefit in patients with acute stroke who undergo mechanical thrombectomy (MT). METHODS: We conducted a systematic review to identify studies that evaluate IAT in patients with acute stroke who undergo MT. Data were extracted from relevant studies found through a search of PubMed, Scopus, and Web of Science until February 2023. Statistical pooling with random effects meta-analysis was undertaken to evaluate odds of functional independence, mortality, and near-complete or complete angiographic recanalization with IAT compared to no IAT. RESULTS: A total of 18 studies were included (3 matched, 14 unmatched, and 1 randomized). The odds ratio (OR) for functional independence (modified Rankin Scale: 0-2) at 90 days was 1.14 (95% confidence interval (CI): 0.95-1.37, p = 0.17, 16 studies involving 7572 patients) with IAT with moderate between-study heterogeneity (I2 = 38.1%). The OR for functional independence with IAT was 1.28 (95% CI: 0.92-1.78, p = 0.15) in studies that were either matched or randomized and 1.24 (95% CI: 0.97-1.58, p = 0.08) in studies with the highest quality score. IAT was associated with higher odds of near-complete or complete angiographic recanalization (OR: 1.65, 95% CI: 1.03-2.65, p = 0.04) in studies that were either matched or of randomized comparisons. CONCLUSION: Although the odds of functional independence appeared to be higher with IAT and MT compared with MT alone, none of the results were statistically significant. A prominent effect of the design and quality of the studies was observed on the association between IAT and functional independence at 90 days.

Neurological Manifestations of COVID-19 (SARS-CoV-2): A Review.

Background: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been associated with many neurological symptoms but there is a little evidence-based published material on the neurological manifestations of COVID-19. The purpose of this article is to review the spectrum of the various neurological manifestations and underlying associated pathophysiology in COVID-19 patients. Method: We conducted a review of the various case reports and retrospective clinical studies published on the neurological manifestations, associated literature, and related pathophysiology of COVID-19 using PUBMED and subsequent proceedings. A total of 118 articles were thoroughly reviewed in order to highlight the plausible spectrum of neurological manifestations of COVID 19. Every article was either based on descriptive analysis, clinical scenarios, correspondence, and editorials emphasizing the neurological manifestations either directly or indirectly. We then tried to highlight the significant plausible manifestations and complications that could be related to the pandemic. With little known about the dynamics and the presentation spectrum of the virus apart from the respiratory symptoms, this area needs further consideration. Conclusion: The neurological manifestations associated with COVID-19 such as Encephalitis, Meningitis, acute cerebrovascular disease, and Guillain Barré Syndrome (GBS) are of great concern. But in the presence of life-threatening abnormal vitals in severely ill COVID-19 patients, these are not usually underscored. There is a need to diagnose these manifestations at the earliest to limit long term sequelae. Much research is needed to explore the role of SARS-CoV-2 in causing these neurological manifestations by isolating it either from cerebrospinal fluid or brain tissues of the deceased on autopsy. We also recommend exploring the risk factors that lead to the development of these neurological manifestations.

Femoral Neuropathy Following Transfemoral Neuroendovascular Procedures. An Analysis of a Prospective Registry.

BACKGROUND AND PURPOSE: Although femoral neuropathy is recognized as an adverse consequence following transfemoral neuroendovascular procedures, no reliable estimates are available. We analyzed data from a prospective registry to ascertain the frequency and characteristics of femoral neuropathy following transfemoral neuroendovascular procedures. METHODS: Consecutive patients who underwent neuroendovascular procedures through the transfemoral route were included. Detailed assessment was performed if any patient reported occurrence of sensory or motor symptoms in the femoral or lower extremity region including neurological examination (sensory/motor deficits) and femoral region ultrasound. RESULTS: Femoral neuropathy was diagnosed following 4 of 270 neurovascular procedures with an occurrence rate of 1.5% (95% confidence intervals = .4-3.7%). The symptoms were exclusively sensory without any motor involvement. The femoral neuropathy appeared to involve anterior femoral cutaneous nerves in all and medial cutaneous branches in 2 patients, and more than one nerve distribution in 1 patient in whom lateral cutaneous nerve appeared to be involved. All patients reported resolution of symptoms within a period ranging from 1 week to 2 months. No local hematoma or arterial pseudoaneurysm was identified at femoral region ultrasound. CONCLUSIONS: Femoral neuropathy is a rare occurrence following transfemoral neuroendovascular procedures and it usually occurs with pure sensory manifestations with complete resolution.

Effect of epidural blood injection on upright posture intolerance in patients with headaches due to intracranial hypotension: A prospective study.

BACKGROUND: We performed a prospective study to quantify changes in various aspects of upright posture intolerance in patients with intracranial hypotension. METHODS: Six patients were provided a standard questionnaire before, immediately after epidural blood patch injection and at follow-up visit within 1 month after epidural blood injection inquiring: (a) How long can they stand straight without any support? (b) Do they feel any sense of sickness when they sit or lie down after standing? (c) How long do they have to wait before they are comfortable standing again after they have stood straight? (d) How effectively and fast can they get up from sitting or lying position to stand straight? and (e) Rate their activities in upright posture without support on a standard vertical visual analogue scale between 100 (can do everything) and 0 (cannot do anything). RESULTS: All patients responded that they could not stand straight for ≥30 min (four responding <5 min) on pretreatment evaluation. All patients reported improvement in this measure immediately postprocedure with two reporting ≥30 min. At follow-up, three patients reported further improvement and one patient reported worsening in this measure. The magnitude of improvement ranged from 10 to 80 points increase immediately postprocedure in their ability to perform activities, while they are standing without any support on visual analogue scale. At follow-up, four patient reported additional improvement in their ability to perform activities, while they are standing without any support (ranged from 10 to 20 points increase compared with immediately postprocedure rating). CONCLUSIONS: We present semiquantitative data on various aspects of upright posture intolerance in patients with intracranial hypotension before and after epidural blood injection.

Assessing acceptability of hypertensive/diabetic patients towards mobile health based behavioral interventions in Pakistan: A pilot study.

INTRODUCTION: Diabetes and hypertension are prevalent chronic diseases among the general population of Pakistan with an exponential progress expected over the upcoming years. Mobile Health services can be an efficient method of helping curtail this rise and improve quality of life of such patients as proven in developed countries. We aim to assess the acceptability of using Mobile Health services among diabetic and hypertensive patients in Pakistan. METHODS: A total of 100 patients were approached in a large tertiary care Government Hospital of Karachi, Pakistan, using a nonprobability convenient sampling technique. Co-authors conducted an interview based sampling of a modified questionnaire to each participant after consent. All data was recorded and analyzed on SPSS 16. RESULTS: A total of 100 patients participated in our study with 66 (66%) males and 34 (34%) females having a mean prevalence age of 54.27. All the 100 participants had easy access to cell phones with 88% participants (88/100) stating that they would be willing to participate in Mobile Health based interventions. A statistically significant number (p=0.014) of them preferred receiving phone calls (85.2%) rather than SMS (14.8%) reminders for these interventions. 85% of the participants even agreed to participate in such intervention on cash incentives. CONCLUSION: The use of phone call reminders or SMS reminders seems like an acceptable and favorable option among hypertensive and diabetic patients. This can greatly improve their self-management and help curtail this rise in the future.

SMS reminders- future in self-care management of diabetes mellitus?

Application of SMS in reminders of medical appointments and delivering medical tests is not new, however its focus on clinical interventions has just begun. Usage of tailored SMS reminders to increase adherence in treatment programs among sick individuals has allowed an interventional role in self-care management of Diabetes Mellitus (DM).
