A systematic cognitive behavioral therapy approach for pediatric disorders of gut-brain interaction.

Cognitive Behavioral Therapy (CBT) for youth with Disorders of Gut-Brain Interaction (DGBIs) is effective; however, there are calls in the field to strengthen the evidence base and identify specific mechanisms of treatment that yield the most benefit for this patient population. A unique, systematic treatment approach of CBT with initial evidence for success for pediatric patients with DGBIs was evaluated to further demonstrate its clinical utility in this population. This was a retrospective study of 42 pediatric patients aged 11-17 years with DGBIs, who were diagnosed and referred for CBT by pediatric gastroenterology providers. Providers also completed a survey rating acceptability and effectiveness of CBT. The systematic CBT approach included 10 sessions delivered by a psychologist at an integrated Pediatric GI Clinic. Review of 42 pediatric charts showed significant decreases in self-reported functional disability, abdominal pain, as well as depression and anxiety symptoms pre- to post-CBT completion. A moderation effect was observed where patients reporting higher levels of depressive symptoms and primary symptom of abdominal pain reported smaller reductions in functional impairment compared to those with lower levels of depression and primary symptom of nausea or vomiting. Pediatric Gastroenterology providers were satisfied with this psychological treatment approach. This study provides evidence for acceptability and effectiveness of implementation of a systematic CBT approach for pediatric DGBIs in an integrated GI clinic, as well as areas worthy of future research, including identifying the most important mechanisms of treatment and factors that influence treatment response.

Acute and long COVID-19 symptoms and associated factors in the omicron-dominant period: a nationwide survey via the online platform Wenjuanxing in China

BackgroundsTo our knowledge, there is no available nationwide data on omicron symptom patterns in China mainland. We aim to determine the acute and long COVID-19 symptoms in the omicron-dominant period and to evaluate its association with risk factors.MethodsWe designed a cross-sectional nationwide study and data about self-reported symptoms were collected by an online platform named Wenjuanxing. Eligible participants were aged 25–65 years and were symptomatic. In this study, the ratios of the number of people of different ages and genders were weighted by the data from the Seventh National Census (2020 years), and validated by a published nationwide representative study through comparing smoking rates. Descriptive indicators were calculated for demographic characteristics, diagnosis ways, and duration time, acute symptoms, hospitalization, severity and long COVID-19 symptoms. And, the associations between risk factors and acute and long COVID-19 symptoms were analyzed by multivariable logistic regression models.ResultsA total of 32,528 individuals diagnosed as COVID-19 infection from October 1, 2022 to February 21, 2023 were included. The first three acute symptoms of COVID-19 infection were fever (69.90%), headache (62.63%), and sore throat (54.29%), respectively. The hospitalization rate within 7 days was 3.07% and symptoms disappearance rate within 21 days was 68.84%, respectively. Among 3983 COVID-19 patients with 3 months or more time difference between first infection and participation into the study, the long COVID-19 rate was 19.68% and the primary symptoms were muscle weakness (19.39%), headache (17.98%) and smell/taste disorder (15.18%). Age groups, smoking, marriage status and vaccination were risk factors for numbers of acute phase symptoms and long COVID-19 symptoms. Lastly, female and current smokers also showed more numbers of symptoms during acute infection period.ConclusionsIn Chinese mainland, our respondent indicated that current smokers and women were associated with acute COVID-19 symptoms, which should be treated with caution due to the lack of representative.

Variation in Interpretation of Provocative Tests for Carpal Tunnel Syndrome

We studied variation in interpretation of specific symptoms during clinical tests for carpal tunnel syndrome to estimate the degree to which surgeons consider pain without paresthesia characteristic of median neuropathy. We invited all upper-extremity surgeon members of the Science of Variation Group to complete a scenario-based experiment. Surgeons read 5-10 clinical vignettes of patients with variation in patient demographics and random variation in symptoms and signs as follows: primary symptoms (nighttime numbness and tingling, constant numbness and loss of sensibility, pain with activity), symptoms elicited by a provocative test (Phalen, Durkan, or Tinel) (tingling, pain), and location of symptoms elicited by the provocative test (index and middle fingers, thumb and index fingers, little and ring fingers, entire hand). Patient factors associated with surgeon interpretation of provocative tests as negative included pain rather than paresthesia during the Phalen, Durkan, or Tinel test and location of symptoms in the entire hand rather than the median nerve distribution. Specialists do not consider pain without paresthesia or a noncharacteristic symptom distribution as characteristic of carpal tunnel syndrome. Awareness that elicitation of pain with Phalen, Durkan, and Tinel tests is regarded by specialists as relatively uncharacteristic of median neuropathy can help limit the potential for both overdiagnosis and overtreatment of median neuropathy as well as underdiagnosis and undertreatment of mental and social health contributions to illness (notable correlates of the intensity and distribution of pain).

Predictors of sexual activity and function in women and men with multiple sclerosis - a preliminary study.

The aim of the study was to determine predictors of sexual activity and function in patients with multiple sclerosis (MS). A total of 134 MS patients were included in the study. Sexual activity and function were assessed by the Changes in Sexual Functioning Questionnaire (CSFQ). Symptoms of sexual dysfunction related to multiple sclerosis (the Multiple Sclerosis Intimacy and Sexuality Questionnaire-19; MSISQ-19), disability status in multiple sclerosis (the Expanded Disability Status Scale; EDSS), gender and age were also taken into account. This analysis indicated that all predictors (gender, age, EDSS score, and all three MSISQ-19 subscales) were significantly associated with the explained variable (sexual activity and function) in the expected direction. Finally, hierarchical regression showed that significant predictors of sexual activity and function were: (a) male gender, (b) age (negative relationship), and (c) primary sexual dysfunction symptoms (negative relationship). Sexual activity and function can be predicted by using the MSISQ-19, which makes it a useful tool for communication between clinicians and patients.

Comparison of the Application Value of Transthoracic Echocardiography in Diagnosing Patent Foramen Ovale Under Different States of Stimulation: A Retrospective Study.

This study aims to evaluate the application value of contrast-enhanced transthoracic echocardiography (cTEE) in the diagnosis of patent foramen ovale (PFO) under different states of stimulation, with the goal of enhancing the accuracy and efficiency of PFO diagnosis. This research consecutively enrolled patients suspected of having PFO from October 2022 to February 2024, presenting primary clinical symptoms such as unexplained syncope, headache, dizziness, and stroke. Patients underwent standard transthoracic echocardiography (TTE) and cTEE under three different states of stimulation (resting state, coughing, and Valsalva maneuver). Based on the presence of microbubbles in the left heart and their initial appearance time, patients were classified into PFO and control groups, with further diagnostic confirmation via transesophageal echocardiography (TEE) or foramen ovale closure procedures. The study results revealed significant differences between the PFO and control groups regarding age (p = 0.034) and headache symptoms (p = 0.001). In the PFO group, TTE showed a higher positivity rate both at rest and during coughing, highlighting the association between PFO and specific clinical symptoms. The number of microbubbles observed during TTE increased significantly under various stimulation states, particularly during the Valsalva maneuver (p < 0.05). This increase became more pronounced as the duration of the maneuver was extended, underscoring the differential response of PFO patients under varied physiological testing conditions, especially during prolonged Valsalva maneuvers. The study confirms the significant value of cTEE in diagnosing PFO under different stimulation states, particularly emphasizing the application of the Valsalva maneuver to significantly improve the sensitivity and specificity of PFO detection. Thus, incorporating cTEE examinations under various stimulation states holds significant clinical importance for enhancing the accuracy and efficiency of PFO diagnosis.

Dance therapy as an intervention for stress and depression: a systematic review and meta-analysis

Currently, no systematic review exists on dance therapy studies for treatment resistant depression. We conducted this systematic review and meta-analysis to determine the effects of dance therapy on the primary symptom clusters of treatment resistant depression, that is, co-morbid stress and depression PROSPERO(CRD42022309685), and identify common dance therapy practices in this population. We searched six databases between January 2001 and March 2024 using the primary key terms: ‘dance therapy’, ‘stress’, ‘depression’, ‘study’, ‘treatment resistance’, and ‘adults’. Reference list checks and citation tracking were conducted. The Downs and Black checklist was used to assess risk of bias. Our search yielded 68 records. Five articles were included (N = 613, 91.2% female), and dosage varied between 15 and 24 h over 3–12 weeks. Results indicated an increase in management strategies rather than symptom reduction. Meta-analyses revealed no statistically significant results for stress and depression. Common dance therapy practices were improvisation, shared rhythm, and structured movement.

Leakage monitoring of carbon dioxide injection well string using distributed optical fiber sensor

Whether the oil and gas fields in the Carbon Capture, Utilization, and Storage (CCUS) project use underground storage or energy supplementation to enhance oil recovery, they must be injected or monitored through the wellbore. Thus, the foundation and requirement for the safety of carbon dioxide (CO2) storage is the wellbore's integrity. When CO2 is dissolved in water, carbonic acid is created, and this acid strongly corrodes underground pipes. Therefore, the integrity issue with CO2 injection wells is more noticeable than with other wellbores. An annular pressure during gas injection is the primary symptom of gas injection string leakage in CO2 injection wells. This study aims to provide real-time pipe string monitoring using a distributed optical fiber temperature sensing system (DTS) and a distributed optical fiber acoustic sensing system (DAS). Variations in temperature and vibration are caused by annulus pressure relief or gas injection. Optical fiber logging, in contrast to traditional logging, has better performance indicators for optical fiber sensing apparatus. To adapt to complex wellbore conditions, it is necessary to enhance the temperature accuracy of DTS and the sensitivity and signal-to-noise ratio of DAS in CO2 drive injection wells based on the features of the gas injection string. To differentiate the leakage signal from the regular fluid flow signal, the energy calculation in the frequency band is done for DAS based on noise reduction, and the signal processing in the frequency band is done by the spectrum characteristics of the CO2 wellbore signal. The translation invariant wavelet algorithm is the primary denoising method for DTS, overcoming the shortcomings of traditional wavelet threshold algorithms such as excessive smoothing and the pseudo-Gibbs phenomenon. Furthermore, the depth correction during the optical cable lowering process is also examined in this paper. A CO2 gas injection well field experiment was conducted using this technology. A 1671m well was dug, and 1631m of optical cable were installed in the tubing. The tubing leakage position was successfully identified through gas injection, annulus pressure relief, and a comparison of DAS and DTS data. The field results demonstrate the accuracy with which the gas injection string integrity can be accurately monitored in real-time using distributed optical fiber sensing technology for CO2 injection wells.

Gastric Bezoars: A Retrospective Analysis of 44 Cases.

BACKGROUND Gastric bezoars are a relatively rare condition. We aim to summarize the clinical characteristics and endoscopic features of patients with gastric bezoars, and analyze the treatment process. MATERIAL AND METHODS The medical records of 44 patients with gastric bezoars treated at Henan Provincial People's Hospital from September 2017 to December 2023 were retrospectively reviewed. RESULTS Among the 44 patients, there were 20 males and 24 females. The average age was 55.36±15.17 years. Abdominal pain was the primary symptom in patients with gastric bezoars. Single gastric bezoars were more common than multiple ones, accounting for 86.4% of all cases. Endoscopic examination revealed ulcers in 36 (81.8%) patients, mainly at the gastric angle and antrum. Single ulcers were more common than multiple ulcers, with most ulcer diameters being less than 2 cm. The occurrence of ulcers was not significantly related to patient age or the size of the bezoars. Endoscopic examination confirmed complete clearance of gastric bezoars in 30 patients. In the 26 patients treated successfully under endoscopy, the number of endoscopic treatments ranged from 1 to 4, with an average of 1.27 interventions per patient. The interval for the second endoscopic re-examination ranged from 2 to 6 days, with an average of 3.87±1.22 days. CONCLUSIONS The most common type of gastric bezoar is phytobezoars. There is a close association between ulcer formation and gastric bezoars. Endoscopic therapy combined with oral treatment can effectively treat gastric bezoars. Most patients require only 1 endoscopic treatment to be successful. The appropriate interval for a follow-up endoscopy after the first endoscopic treatment is around 4 days.

“Sigma-1 receptor modulation by clemastine highlights its repurposing as neuroprotective agent against seizures and cognitive deficits in PTZ-kindled rats”

Epilepsy is a neurological disorder characterized by recurrent spontaneous seizures alongside other neurological comorbidities. Cognitive impairment is the most frequent comorbidity secondary to progressive neurologic changes in epilepsy. Sigma 1 receptors (σ1 receptors) are involved in the neuroprotection and pathophysiology of both conditions and targeting these receptors may have the potential to modulate both seizures and comorbidities. The current research demonstrated the effect of clemastine (10 mg/kg, P.O.), a non-selective σ1 receptor agonist, on pentylenetetrazol (PTZ) (35 mg/kg, i.p., every 48 h for 14 doses)-kindling rats by acting on σ1 receptors through its anti-inflammatory/antioxidant capacity. Clemastine and phenytoin (30 mg/kg, P.O.) or their combination were given once daily. Clemastine treatment showed a significant effect on neurochemical, behavioural, and histopathological analyses through modulation of σ1 receptors. It protected the kindling animals from seizures and attenuated their cognitive impairment in the Morris water maze test by reversing the PTZ hippocampal neuroinflammation/oxidative stress state through a significant increase in inositol-requiring enzyme 1 (IRE1), x-box binding protein 1 (XBP1), along with a reduction of total reactive oxygen species (TROS) and amyloid beta protein (Aβ). The involvement of σ1 receptors in the protective effects of clemastine was confirmed by their abrogation when utilizing NE-100, a selective σ1 receptor antagonist. In light of our findings, modulating σ1 receptors emerges as a compelling therapeutic strategy for epilepsy and its associated cognitive impairments. The significant neuroprotective effects observed with clemastine underscore the potential of σ1 receptor-targeted treatments to address both the primary symptoms and comorbidities of neurological disorders.

Therapy with botulinum neurotoxin for Parkinson's disease.

Botulinum neurotoxin (BoNT) has been in use since the 1970's. Its effect is reached mainly by inhibiting the release of acetylcholine in the synaptic gap of motor neurons or at the motor end plate and the parasympathetic ganglia. In the case of Parkinson's disease, it is used to treat several motor and non-motor symptoms. Within recent years increasingly numerous possible fields of application of BoNT have been found for the treatment of Parkinson's disease, and for some specific symptoms it has in fact become the therapy of choice, while for others it is but one of the therapeutic options that come into consideration when others are not sufficiently effective. In the following, we intend to outline the indications, the possible side effects and also the approvals for therapies with botulinum toxin in the primary and secondary symptoms of Parkinson's disease.

Microcirculatory dysfunction in hypertrophic cardiomyopathy with chest pain assessed by angiography-derived microcirculatory resistance

Chest pain, a common initial symptom in hypertrophic cardiomyopathy (HCM) patients, is closely linked to myocardial ischemia, despite the absence of significant coronary artery stenosis. This study explored microvascular dysfunction in HCM patients by employing angiography-derived microcirculatory resistance (AMR) as a novel tool for comprehensive assessment. This retrospective analysis included HCM patients with chest pain as the primary symptom and control patients without cardiac hypertrophy during the same period. The AMR was computed through angiography, providing a wire-free and adenosine-free index for evaluating microcirculatory function. Propensity score matching ensured balanced demographics between groups. This study also investigated the correlation between the AMR and clinical outcomes by utilizing echocardiography and follow-up data. After matching, 76 HCM patients and 152 controls were analyzed. While there was no significant difference in the incidence of epicardial coronary stenosis, the AMR of three epicardial coronary arteries was markedly greater in HCM patients. The criterion of an AMR ≥ 250 mmHg*s/m was that 65.7% of HCM patients experienced coronary microvascular dysfunction (CMD). Independent risk factors for CMD included increased left ventricular (LV) wall thickness (OR = 1.209, 95% CI 1.013–1.443, p = 0.036). Furthermore, an AMR_LAD ≥ 250 mmHg*s/m had an increased cumulative risk of the endpoint (log-rank p = 0.023) and was an independent risk factor for the endpoint (HR = 11.64, 95% CI 1.13–120.03, p = 0.039), providing valuable prognostic insights.

The Association of Medical Cannabis Use with Pain Levels and Opioid Use in Illinois’ Opioid Alternative Pilot Program

Objective The state of Illinois’ Opioid Alternative Pilot Program (OAPP) is the first and only official harm-reduction program in the US to address the opioid crisis via facilitation of safe and legal access to medical cannabis. This study evaluates the association of medical cannabis use with pain level and frequency of opioid use in the first cohort of OAPP participants in 2019. Methods A survey was sent OAPP enrollees between February and July 2019. Cannabis users (n = 626) were compared to non-users (n = 234) to determine whether there was an association between cannabis use and self-reported (a) pain level and (b) frequency of opioid use. Backward stepwise regression models were used. Results A total of 860 participants was included in the analysis. Overall, 75% of the study sample reported pain as their primary medical symptom, and 67% of cannabis users reported having a disability. The mean difference in pain level between cannabis users and non-users was 4.5 units (on a 100-point scale) higher among cannabis users than non-users (p = 0.03); and cannabis use was statistically associated with pain level. High-frequency opioid users had lower odds of reporting cannabis use within the past year than low/no opioid users. Conclusions Although there was a statistical association between cannabis use and pain, the difference of 4.5 points in pain level between users and non-users was too small to reflect a clinically meaningful relative difference. This study may provide useful information to providers and clinicians about how the OAPP and similar programs may reduce opioid use and improve health outcomes.

Sex differences in post-COVID ageusia/anosmia in the United States

Post-COVID Conditions (PCC) involve persistent symptoms associated with COVID-19 that continue beyond four weeks of initial infection. Sex has been shown to be related with COVID-19 severity and symptoms. The purpose of this study is to assess the loss of taste (ageusia) or smell (anosmia) among U.S. residents who had PCC and examine its specific association with sex. The data source for this cross-sectional study was 2022 Behavioral Risk Factor Surveillance System (BRFSS), a U.S. national dataset. Participants were included if they had COVID-19, reported experiencing PCC, and identified their primary PCC symptom. Overall, 23,824 participants were included in the study. In multivariable logistic regression analysis, adjusted odds ratio for males compared to females was 1.18 (95 % CI: 1.03–1.35; p=0.0165). Participants who were aged <50 years as compared with those who were aged ≥50 years, non-Hispanic white as compared with non-Hispanic black, had BMI ≤ 25 as compared with BMI ≥ 30, had no reported chronic condition as compared with those who did report a chronic condition, and had ≤high school education as compared with those who had > high school education had higher odds of reporting PCC-related ageusia/anosmia in this multivariable model. Among people with PCC, males had an 18 % higher odds of reporting PCC-related ageusia/anosmia as their primary symptom of PCC compared to females. Findings from our study can help identify patients affected by PCC-related ageusia/anosmia who would benefit from early referral for supportive care, such as counseling or interventions that can alleviate this dysfunction.

Tibial nerve stimulation in the management of primary sexual dysfunction in patients with multiple sclerosis: a pilot randomized control trial.

Sexual dysfunction (SD) is a common symptom that affects 40-90% of patients with multiple sclerosis (MS). Previous studies have highlighted the negative impact of sexual dysfunction in the mental health status and overall quality of life in patients with MS. The aim of this study was to examine the effects of transcutaneous tibial nerve stimulation (TTNS) in the primary SD symptoms in patients with MS. A total of 40 participants were randomized (1:1 ratio) to either TTNS or Sham group and received three 20min sessions over the course of two months. Pre and post intervention SD was evaluated using the Multiple Sclerosis Intimacy Questionnaire (MISQ-15). Statistically significant improvements in the aspects of primary sexual dysfunction were observed in the TTNS group pre-post intervention (specifically erectile function (for males)/vaginal lubrication (for females) (p < .001), orgasm quality and satisfaction for both male and female patients (p < .001), sexual desire (p < .05) and bladder related symptomatology (p < .005). In the sham group pre-post intervention, the only observed improvement was in the sexual desire aspect (p < .05). Post intervention the groups significantly differed erectile function/vaginal lubrication and orgasm quality and satisfaction (p < .05). Our findings underline the efficacy of TTNS in improving primary SD symptoms as well as bladder problems in both male and female patients with MS. TTNS demonstrated significant improvement in the following domains: erectile function, vaginal lubrication, orgasm quality, satisfaction, bladder-related symptoms, and sexual desire.

Medical oxygen production, supply, and infrastructure augmentation during the COVID-19 pandemic in India: A narrative review

According to the World Health Organization, the primary symptoms of COVID-19 include fever, cough, and fatigue, while more serious cases present with dyspnea (difficulty breathing) and chest pain. The medical use of oxygen therapy is a common life support treatment for numerous diseases at multiple levels of health care in India. An abrupt spike in medical oxygen demand (nearly 100 &amp;ndash; 200 fold) has been observed in regions such as South America, Africa, and Asia, including India. Governments of the respective countries have implemented policy decisions to tackle medical oxygen shortage during the pandemic. In this narrative review, we describe and summarize the actions taken by the Indian government to manage the medical oxygen requirement during the deadly COVID-19 waves in India. Searches were conducted on PubMed, Scopus, Google Scholar databases, and websites of various ministries and departments of the Government of India, covering the period from January 2020 to January 31, 2023. Qualitative data were extracted using pre-defined themes from published documents related to medical oxygen supply during the COVID-19 pandemic in the Indian context. This narrative review summarizes the state of medical oxygen during the COVID-19 pandemic, focusing on medical oxygen production, supply, infrastructure augmentation, pressure swing adsorption plants, capacity building, web application, and monitoring mechanisms. The 76th World Health Assembly has also adopted the Access to Medical Oxygen Resolution to prevent deaths and ensure that no country faces an oxygen shortage, as seen during the COVID-19 pandemic.

Beyond diagnosis: exploring coeliac disease incidence alongside clinical and laboratory characteristics of newly diagnosed children in Slovenia.

Coeliac disease is characterized by a wide array of clinical presentations. The focus of our study was to comprehensively assess the clinical manifestations of coeliac disease in newly diagnosed children in Slovenia. Our objectives include estimating the incidence of the disease in children in 2022. In this prospective study, Slovenian paediatric gastroenterologists were invited to provide patient data using medical records of children under 19 diagnosed with coeliac disease from March 2021 to October 2023. Patient data were collected through a dedicated web-based form adapted from the CD SKILLS project, including data on clinical manifestations and laboratory results. Furthermore, the study included an estimation of the incidence of coeliac disease in children and adolescents in Slovenia in 2022. Analysis involved data from 160 children and adolescents (median age: 8 years; 61.9% female). Overall, 16.9% were asymptomatic at diagnosis and 29.4% belonged to a high-risk group for coeliac disease. Among symptomatic cases ( N = 133), abdominal pain was the leading symptom (44.4%), followed by anaemia (12.0%) and diarrhoea (10.5%). Malabsorption symptoms were more prevalent in very young children. Anaemia was found in 22.8 and 10.7% had abnormal alanine aminotransferase levels. The estimated incidence of coeliac disease in Slovene children in 2022 was 17.5/100 000. Abdominal pain emerged as the primary symptom of coeliac disease in children and adolescents, except in very young children where malabsorption symptoms were predominant. Our observation of a lower prevalence of abnormal liver function tests suggests subclinical coeliac disease may be less common in children. Moreover, the calculated coeliac disease incidence in Slovenia aligns with existing data.

Spontaneous intracranial hypotension - a spinal disease.

Spontaneous intracranial hypotension (SIH) remains an underdiagnosed condition despite increasing awareness due to recent scientific advances. Diagnosis can be delayed by the broad clinical presentation and imaging pitfalls. This results in a high degree of physical impairment for patients, including social and psychological sequelae as well as long-term damage in the case of delayed diagnosis and treatment.The study is based on a selective literature search on PubMed including articles from 1990 to 2023 and the authors' clinical experience from working in a CSF center.SIH mostly affects middle-aged women, with the primary symptom being position-dependent orthostatic headache. In addition, there is a broad spectrum of possible symptoms that can overlap with other clinical conditions and therefore complicate the diagnosis. The causative spinal CSF loss can be divided into three main types: ventral (type 1) or lateral (type 2) dural leak and CSF-venous fistula (type 3). The diagnosis can be made using a two-stage workup. As a first step, noninvasive MRI of the head and spine provides indicators of the presence of SIH. The second step using focused myelography can identify the exact location of the cerebrospinal fluid leak and enable targeted therapy (surgical or interventional). Intrathecal pressure measurement or intrathecal injection of gadolinium is no longer necessary for primary diagnosis. Serious complications in the course of the disease can include space-occupying subdural hematomas, superficial siderosis, and symptoms of brain sagging, which can lead to misinterpretations. Treatment consists of closing the dural leak or the cerebrospinal fluid fistula. Despite successful treatment, a relapse can occur, which highlights the importance of follow-up MRI examinations and emphasizes the chronic nature of the disease. This paper provides an overview of the diagnostic workup of patients with suspected SIH and new developments in imaging and therapy. · SIH is an underdiagnosed condition with a wide range of possible symptoms.. · The first diagnostic step using MRI provides indications of the presence of SIH.. · The second diagnostic step using (dynamic) myelography can identify the CSF leak.. · Collaboration with a CSF center is advisable for further diagnosis and treatment.. · Prompt detection and treatment of SIH improves the outcome.. · Zander C, Wolf K, El Rahal A et al.

Myxoinflammatory fibroblastic sarcoma of the liver: Case report and literature review.

Myxoinflammatory fibroblastic sarcoma (MIFS) is a rare low-grade malignant soft tissue sarcoma that primarily affects the distal extremities in adults, with the highest incidence in patients in their 40s and 50s. It has a high local recurrence rate and a low metastasis rate. Although MIFSs have been documented in other sites, an MIFS in the liver is highly unusual. Herein, we present a case of a patient with hepatic MIFS. The patient was a 58-year-old Chinese man with abdominal pain as the primary symptom. Abdominal computed tomography and magnetic resonance imaging revealed a mass in the right posterior lobe of the liver. The patient underwent surgical excision, and the excised specimen was identified as MIFS. Three years later, the patient returned to our hospital for abdominal pain. Computed tomography and magnetic resonance imaging revealed a mass in liver segments 2/3/4. Postoperative pathological examination of the tumor revealed the recurrence of MIFS. The patient underwent surgical resection of the MIFS. The patient received multiple pirarubicin-based chemotherapy treatments and an ALK inhibitor (anlotinib) within 6 months after surgery, but the tumor recurred. MIFS can not only occur in the proximal limbs, trunk, head, and neck but can also affect the abdominal organs. Surgical resection remains the primary treatment option for MIFS in the absence of any contraindications. Because the recurrence rate of MIFS is high, meticulous long-term monitoring is required.

Novel therapies for cancer-induced bone pain

Cancer pain is a growing problem, especially with the substantial increase in cancer survival. Reports indicate that bone metastasis, whose primary symptom is bone pain, occurs in 65–75% of patients with advanced breast or prostate cancer. We optimized a preclinical in vivo model of cancer-induced bone pain (CIBP) involving the injection of Lewis Lung Carcinoma cells into the intramedullary space of the femur of C57BL/6 mice or transgenic mice on a C57BL/6 background. Mice gradually reduce the use of the affected limb, leading to altered weight bearing. Symptoms of secondary cutaneous heat sensitivity also manifest themselves. Following optimization, three potential analgesic treatments were assessed; 1) single ion channel targets (targeting the voltage-gated sodium channels NaV1.7, NaV1.8, or acid-sensing ion channels), 2) silencing µ-opioid receptor-expressing neurons by modified botulinum compounds, and 3) targeting two inflammatory mediators simultaneously (nerve growth factor (NGF) and tumor necrosis factor (TNF)). Unlike global NaV1.8 knockout mice which do not show any reduction in CIBP-related behavior, embryonic conditional NaV1.7 knockout mice in sensory neurons exhibit a mild reduction in CIBP-linked behavior. Modified botulinum compounds also failed to cause a detectable analgesic effect. In contrast, inhibition of NGF and/or TNF resulted in a significant reduction in CIBP-driven weight-bearing alterations and prevented the development of secondary cutaneous heat hyperalgesia. Our results support the inhibition of these inflammatory mediators, and more strongly their dual inhibition to treat CIBP, given the superiority of combination therapies in extending the time needed to reach limb use score zero in our CIBP model.

The range of endometrial pathologies in patients with abnormal uterine bleeding at a tertiary care center in central India

Abstract Background: Endometrial disorders are among the most common gynecological conditions globally. Abnormal uterine bleeding (AUB) refers to any irregularity in the timing, volume, or pattern of menstrual blood flow. This study investigates the histopathological spectrum of endometrial changes across various age groups in patients presenting with AUB as their primary symptom. Materials and Methods: The study analyzed 226 endometrial biopsies/specimens collected over two years from patients with AUB as the main complaint. These specimens were processed, and slides stained with hematoxylin and eosin (H&amp;E) were examined to determine the endometrial patterns. A chi-square test assessed the relationship between age and specific endometrial pathologies. Observations and Results: Most of the 226 cases were from perimenopausal women (40–49 years), representing 57% of the total, with proliferative endometrium being the most common pattern (40.9%). About 20% of the cases were in the reproductive age group (&lt;40 years), where typical hyperplasia was the most prevalent pattern (45.7%). Additionally, 23% of the cases involved postmenopausal women (&gt;49 years), with endometrioid carcinoma being the most frequent pattern observed. Other endometrial patterns included disordered proliferative endometrium, endometritis, endometrial polyps, Arias–Stella reaction, and progesterone effects. Conclusion: Patients with AUB present with a wide range of endometrial patterns, from normal cyclic endometrium to malignancies. Histopathological examination remains the gold standard for diagnosing AUB, showing a significant association between endometrial lesions and age.
