Endoscopic endonasal resection of symptomatic Rathke's cleft cysts: outcomes of the strategy to maintain the fenestration open.

PURPOSE: The study intends to clarify the optimal endoscopic endonasal surgical strategy for symptomatic Rathke's cleft cysts (RCCs). METHODS: We retrospectively analyzed patients with RCCs that underwent EEA surgery. The strategy for surgical and reconstruction method selection was presented. Patients were split into groups of fenestration open or closed. Pre- and postoperative symptoms, imaging, ophthalmologic, and endocrinologic exams were reviewed. The incidence of complications and the recurrence rates were determined. RESULTS: The 75 individuals were all received primary operations. The fenestration closed group contained 32 cases, while the fenestration open group contained 43 cases. The median follow-up period was 39 months. The three primary complaints were headache (n = 51, 68.00%), vision impairment (n = 45, 60.00%), and pituitary dysfunction (n = 16, 21.33%). Of the 51 patients with preoperative headaches, 48 (94.12%) reported improvement in their symptoms following surgery. Twenty-three out of 45 patients (51.11%) experienced an improvement in visual impairment. Pituitary dysfunction was found improved in 14 out of 16 individuals (87.50%). There was no discernible difference in the rate of symptom alleviation between both groups. There were three patients (3/75, 4.00%) had cyst reaccumulation. One of them (1/75, 1.33%), which needed reoperation, was healed using pterional approach. In term of complications, cerebral infections occurred in two patients (2/75, 2.67%). Both of them recovered after antibiotic treatment. No postoperative cerebrospinal fluid rhinorrhea occurred. One patient (1/75, 1.33%) in the open group experienced epistaxis. There was no persistent hypopituitarism or diabetes insipidus (DI). Analysis of headache related factors showed that the presence of wax like nodules was related to it. CONCLUSION: RCC was successfully treated with endoscopic endonasal surgery with few problems when the fenestration was kept as open as feasible. Preoperative identification of T2WI hypointense nodules may be a potential reference factor for surgical indication.

PACAP38/mast-cell-specific receptor axis mediates repetitive stress-induced headache in mice.

BACKGROUND: Pain, an evolutionarily conserved warning system, lets us recognize threats and motivates us to adapt to those threats. Headache pain from migraine affects approximately 15% of the global population. However, the identity of any putative threat that migraine or headache warns us to avoid is unknown because migraine pathogenesis is poorly understood. Here, we show that a stress-induced increase in pituitary adenylate cyclase-activating polypeptide-38 (PACAP38), known as an initiator of allosteric load inducing unbalanced homeostasis, causes headache-like behaviour in male mice via mas-related G protein-coupled receptor B2 (MrgprB2) in mast cells. METHODS: The repetitive stress model and dural injection of PACAP38 were performed to induce headache behaviours. We assessed headache behaviours using the facial von Frey test and the grimace scale in wild-type and MrgprB2-deficient mice. We further examined the activities of trigeminal ganglion neurons using in vivo Pirt-GCaMP Ca2+ imaging of intact trigeminal ganglion (TG). RESULTS: Repetitive stress and dural injection of PACAP38 induced MrgprB2-dependent headache behaviours. Blood levels of PACAP38 were increased after repetitive stress. PACAP38/MrgprB2-induced mast cell degranulation sensitizes the trigeminovascular system in dura mater. Moreover, using in vivo intact TG Pirt-GCaMP Ca2+ imaging, we show that stress or/and elevation of PACAP38 sensitized the TG neurons via MrgprB2. MrgprB2-deficient mice showed no sensitization of TG neurons or mast cell activation. We found that repetitive stress and dural injection of PACAP38 induced headache behaviour through TNF-a and TRPV1 pathways. CONCLUSIONS: Our findings highlight the PACAP38-MrgprB2 pathway as a new target for the treatment of stress-related migraine headache. Furthermore, our results pertaining to stress interoception via the MrgprB2/PACAP38 axis suggests that migraine headache warns us of stress-induced homeostatic imbalance.

Prevalence of headaches in healthcare workers while using personal protective equipment during the COVID-19 pandemic: a systematic review and meta-analysis.

OBJECTIVES: During the COVID-19 pandemic, healthcare workers (HCWs) are at a serious risk of contracting this virus. Therefore, they should use personal protective equipment (PPE) to protect themselves. Long-term use of these devices has led to many side effects, including headaches. This study investigated the prevalence of headaches related to using PPE in HCWs during the COVID-19 pandemic. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Embase, PubMed, Scopus and Web of Science databases were searched from December 2019 to February 2023. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: All cross-sectional studies that investigated the prevalence of headache complications caused by PPE were included. DATA EXTRACTION AND SYNTHESIS: Two researchers reviewed the articles separately and independently. The Appraisal Tool for Cross-Sectional Studies was used to address study design quality and the risk of bias in cross-sectional studies. The heterogeneity of the studies was checked with the I2 statistic, and due to the high heterogeneity, the random effects model was used for synthesis. Data were analysed using Comprehensive Meta-Analysis software V.3.3.70. RESULTS: Out of 3218 articles retrieved for all side effects, 40 were eligible for this meta-analysis. The prevalence of headaches related to the use of PPE in these 40 studies, with a sample size of 19 229 people, was 43.8% (95% CI 43.1% to 44.6%, I2=98.6%, p<0.001). Based on the meta-regression results, no significant relationship was observed between the prevalence of headaches and variables such as year of publication, study location, sample size and quality of studies. CONCLUSION: Headache is one of the common side effects of PPE, which can interfere with HCWs' performance. It is suggested that manufacturers improve the quality of their equipment while healthcare managers should equip and train staff adequately to minimise side effects, ensuring health and enhanced service delivery.

A comprehensive analysis of patients with cerebral arteriovenous malformation with headache: assessment of risk factors and treatment effectiveness.

BACKGROUND: Due to the high mortality and disability rate of intracranial hemorrhage, headache is not the main focus of research on cerebral arteriovenous malformation (AVM), so research on headaches in AVM is still scarce, and the clinical understanding is shallow. This study aims to delineate the risk factors associated with headaches in AVM and to compare the effectiveness of various intervention treatments versus conservative treatment in alleviating headache symptoms. METHODS: This study conducted a retrospective analysis of AVMs who were treated in our institution from August 2011 to December 2021. Multivariable logistic regression analysis was employed to assess the risk factors for headaches in AVMs with unruptured, non-epileptic. Additionally, the effectiveness of different intervention treatments compared to conservative management in alleviating headaches was evaluated through propensity score matching (PSM). RESULTS: A total of 946 patients were included in the analysis of risk factors for headaches. Multivariate logistic regression analysis identified that female (OR 1.532, 95% CI 1.173-2.001, p = 0.002), supply artery dilatation (OR 1.423, 95% CI 1.082-1.872, p = 0.012), and occipital lobe (OR 1.785, 95% CI 1.307-2.439, p < 0.001) as independent risk factors for the occurrence of headaches. There were 443 AVMs with headache symptoms. After propensity score matching, the microsurgery group (OR 7.27, 95% CI 2.82-18.7 p < 0.001), stereotactic radiosurgery group(OR 9.46, 95% CI 2.26-39.6, p = 0.002), and multimodality treatment group (OR 8.34 95% CI 2.87-24.3, p < 0.001) demonstrate significant headache relief compared to the conservative group. However, there was no significant difference between the embolization group (OR 2.24 95% CI 0.88-5.69, p = 0.091) and the conservative group. CONCLUSIONS: This study identified potential risk factors for headaches in AVMs and found that microsurgery, stereotactic radiosurgery, and multimodal therapy had significant benefits in headache relief compared to conservative treatment. These findings provide important guidance for clinicians when developing treatment options that can help improve overall treatment outcomes and quality of life for patients.

Post-Covid Conditions and their Effects on the Cardiovascular System.

Background: Rising global concerns about COVID-19 recently gained more research attention due to the ease of person-to-person transmission, various symptoms after healing, and the shortage of effective antiviral therapy. The study aims to analyze post-COVID conditions and clinical manifestations of cardiovascular lesions in patients recovering from COVID-19 infection. Methods: A practical examination of post-COVID conditions manifestation was conducted in a prospective cohort study, involving 250 patients diagnosed with COVID-19 between June 1, 2021, and August 31, 2021. The study specifically focused on analyzing the cardiovascular effects of COVID-19, utilizing data from a subgroup of 200 patients previously discharged from the hospital with elevated troponin levels. The cardiovascular variables assessed included tachycardia, ischemia, heart attack, myocarditis, hypertension, blood clots, and heart failure. Results: It has been observed that among surviving patients, the following symptoms persisted: anosmia/ageusia (59%), severe dyspnea (36.7%), palpitations and complaints related to the cardiovascular sys-tem (15.8%), headaches (13.2%), arthralgia (11.7%), myalgia (9.8%), and hair problems (≥5%). By the 60th day, a reduction in symptoms by 5-10% was noted, and by the 90th day, a decrease in activity by 25-35% was observed. Patients aged 40-60 years exhibited the highest percentage of cardiovascular diseases (75%). Conclusions: Consequently, the SARS-CoV-2 virus underscores the critical importance of cardiological attention in patient care. Cardiac screening results in individuals with COVID-19 reveal a significant prevalence of serious heart problems, affecting over half of the patients. This emphasizes the necessity for heightened vigilance and specialized cardiac care when managing patients with COVID-19.

Six Year Old With Chronic Headache: An Unexpected Meningitis Mimic.

The constellation of fevers accompanied by headache and vomiting is a red flag for clinicians that appropriately triggers evaluation for meningitis and other life-threatening diagnoses. When symptoms persist even after these conditions are ruled out, patient care becomes more challenging. We present the case of a 6-year-old male with a history of autism spectrum disorder who presented with 6 months of headaches and associated vomiting and intermittent fevers with negative infectious workup despite cerebrospinal fluid pleocytosis. Serial neuroimaging and laboratory evaluation ultimately led to a diagnosis of myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) presenting as aseptic meningitis. The clinical and radiographic findings of MOGAD are widely variable and overlap with several other inflammatory conditions, which makes diagnosis challenging. This case highlights the importance of recognizing this rare MOGAD presentation as an infectious meningitis mimic.

Headache in Multiple Sclerosis: A Narrative Review.

Background: Multiple sclerosis (MS) is a chronic inflammatory demyelinating disorder of the central nervous system characterized by autoimmune-mediated damage to oligodendrocytes and subsequent myelin destruction. Clinical implications: Clinically, the disease presents with many symptoms, often evolving over time. The insidious onset of MS often manifests with non-specific symptoms (prodromal phase), which may precede a clinical diagnosis by several years. Among them, headache is a prominent early indicator, affecting a significant number of MS patients (50-60%). Results: Headache manifests as migraine or tension-type headache with a clear female predilection (female-male ratio 2-3:1). Additionally, some disease-modifying therapies in MS can also induce headache. For instance, teriflunomide, interferons, ponesimod, alemtuzumab and cladribine are associated with an increased incidence of headache. Conclusions: The present review analyzed the literature data on the relationship between headache and MS to provide clinicians with valuable insights for optimized patient management and the therapeutic decision-making process.

Changes in retinal nerve fiber layer thickness may be the cause of post-COVID-19 headaches.

OBJECTIVE: The prevalence of post-COVID headaches is not low. The eye can be affected by this infection, but it is not clear yet what the relationship is between persistent headaches and the thickness of the retinal nerve fiber layer (RNFL) after COVID-19 infection this study aims to investigate the relationship between these subjects. METHODS: In this retrospective study, in patients who have had a persistent headache, SD-OCT analysis of RNFL was obtained, and RNLF thickness values before and after COVID-19 infection were analyzed. RESULTS: A total of 26 eyes from 13 patients (nine (69.2%) females, four (30.8%) males) with persistent headaches after COVID-19 infection were studied. The average age was 47,35 years for females and 63 years for males. The mean RNFL thickness of both eyes between before and after COVID-19 infection decreased, which was statistically significant. CONCLUSION: In this study, a correlation between headache and changes in RNLF after COVID-19 infection was found. It may have wider ramifications to look into the COVID-19-associated headache phenotype of people with a history of migraines, contributing to a more comprehensive understanding of migraine pathogenesis. This relationship can provide further insight into this infection.

Persistent headache without neurologic deficit from a spontaneous vertebral artery dissection.

INTRODUCTION: Non-traumatic headache is a common complaint seen in the emergency department (ED), accounting for 2.3% of ED visits per year in the United States (Munoz-Ceron et al., 2019). When approaching the workup and management of headache, an emergency medicine physician is tasked with generating a deadly differential by means of a thorough history and physical exam to determine the next best steps. CASE: A 21-year-old male presented to the emergency department with a debilitating new-onset headache, preceded by an isolated vertiginous event 3 days prior. He was found to have a normal neurologic examination. A non-contrast CT scan of the head revealed a large hypodensity within the left cerebellum with a subsequent MRA of the brain and neck notable for a left vertebral artery dissection, complicated by an ischemic cerebellar stroke. DISCUSSION: With an estimated incidence of 1-5 per 100,000, vertebral artery dissection is a rare cause of stroke within the general population and carries with it a high degree of morbidity and mortality (Rodallec et al., 2008). Vertebral artery dissection is a result of blood penetrating the intimal wall of the artery to form an intramural hematoma. Diagnosis can be difficult in cases presenting subacutely but a thorough history evaluating for red flags and using simple but highly sensitive exams such as the bedside HINTS exam can increase pretest probability of stroke. Clinical syndromes, red flags, and time from onset of symptoms should guide imaging modalities such as CT, CTA, MRI, and MRA in detection of small ischemic changes, intimal flaps, and luminal thromboses. CONCLUSION: Vertebral artery dissection should remain high on the differential for an emergency medicine physician when history is suggestive of a new onset headache, preceded by vertiginous symptoms. An absence of recent trauma and a normal neurologic examination does not eliminate the diagnosis.

Factors influencing delivery-related complications and their consequences in hard-to-reach areas of Bangladesh.

BACKGROUND AND OBJECTIVES: Bangladesh's high maternal mortality ratio is exacerbated by delivery-related complications, particularly in hard-to-reach (HtR) areas with limited healthcare access. Despite this, few studies have explored delivery-related complications and factors contributing to these complications among the disadvantaged population. This study aimed to investigate the factors contributing to delivery-related complications and their consequences among the mothers residing in the HtR areas of Bangladesh. METHODS: Data were collected using a cross-sectional study design from 13 HtR sub-districts of Bangladesh between September 2019 and October 2019. Data from 1,290 recently delivered mothers were analysed. RESULTS: Around 32% (95% CI: 29.7-34.8) of the mothers reported at least one delivery-related complication. Prolonged labour pain (21%) was the highest reported complication during the delivery, followed by obstructive labour (20%), fever (14%), severe headache (14%). Mothers with higher education, a higher number of antenatal care (ANC) visits, complications during ANC, employed, and first-time mothers had higher odds of reporting delivery-related complications. More than one-half (51%) of these mothers had normal vaginal delivery. Nearly one-fifth (20%) of mothers who reported delivery-related complications were delivered by unskilled health workers at homes. On the other hand, about one-fifth (19%) of the mothers without any complications during delivery had a caesarean delivery. Nine out of ten of these caesarean deliveries were done at the private facilities. CONCLUSION: Delivery-related complications are significantly related to a woman's reproductive history and other background characteristics. Unnecessary caesarean delivery is prominent at private facilities.

Clinical presentation of post-COVID pain and its impact on quality of life in long COVID patients: a cross-sectional household survey of SARS-CoV-2 cases in Bangladesh.

BACKGROUND: Pain is one of the prevalent Long COVID Symptoms (LCS). Pain interferes with the quality of life (QoL) and induces disease burden. PURPOSE: The study aimed to elicit the clinical presentation of pain and determine the relationships between QoL and pain in LCS. METHODS: This household cross-sectional study of 12,925 SARS-CoV-2 cases between July and December 2021 was carried out in eight administrative divisions of Bangladesh. Stratified random sampling from the cases retrieved from the Ministry of Health was employed. Symptom screening was performed through COVID-19 Yorkshire Rehabilitation Scale, and long COVID was diagnosed according to World Health Organization (WHO) criteria. The analyses were conducted using IBM SPSS (Version 20.00). RESULTS: The prevalence of pain in long COVID was between 01 and 3.1% in the studied population. The study also found five categories of pain symptoms as LCS in Bangladesh: muscle pain 3.1% (95% CI; 2.4-3.8), chest pain 2.4% (95% CI; 1.8-3.1), joint pain 2.8% (95% CI; 2.2-2.3), headache 3.1% (95% CI; 2.4-3.8), and abdominal pain 0.3% (95% CI; 0.01-0.5). People with LCS as pain, multiple LCS, and longer duration of LCS had significantly lower quality of life across all domains of the WHOQOL-BREF (P < 0.001) compared to asymptomatic cases. CONCLUSION: Three out of ten people with long COVID experience painful symptoms, which can significantly reduce their quality of life. Comprehensive rehabilitation can improve the symptoms and reduce the burden of the disease.

Predictive performance of the common red flags in emergency department headache patients: a HEAD and HEAD-Colombia study.

OBJECTIVES: Only a small proportion of patients presenting to an ED with headache have a serious cause. The SNNOOP10 criteria, which incorporates red and orange flags for serious causes, has been proposed but not well studied. This project aims to compare the proportion of patients with 10 commonly accepted red flag criteria (singly and in combination) between patients with and without a diagnosis of serious secondary headache in a large, multinational cohort of ED patients presenting with headache. METHODS: Secondary analysis of data obtained in the HEAD and HEAD-Colombia studies. The outcome of interest was serious secondary headache. The predictive performance of 10 red flag criteria from the SNNOOP10 criteria list was estimated individually and in combination. RESULTS: 5293 patients were included, of whom 6.1% (95% CI 5.5% to 6.8%) had a defined serious cause identified. New neurological deficit, history of neoplasm, older age (>50 years) and recent head trauma (2-7 days prior) were independent predictors of a serious secondary headache diagnosis. After adjusting for other predictors, sudden onset, onset during exertion, pregnancy and immune suppression were not associated with a serious headache diagnosis. The combined sensitivity of the red flag criteria overall was 96.5% (95% CI 93.2% to 98.3%) but specificity was low, 5.1% (95% CI 4.3% to 6.0%). Positive predictive value was 9.3% (95% CI 8.2% to 10.5%) with negative predictive value of 93.5% (95% CI 87.6% to 96.8%). CONCLUSION: The sensitivity and specificity of the red flag criteria in this study were lower than previously reported. Regarding clinical practice, this suggests that red flag criteria may be useful to identify patients at higher risk of a serious secondary headache cause, but their low specificity could result in increased rates of CT scanning.
