Associations of Severity of Dry Eye Symptoms and Signs with the Quality of Life in the Dry Eye Assessment and Management (DREAM) Study.

To assess associations of dry eye disease (DED) severity of symptoms and signs with the quality of life in patients with moderate-to-severe DED. At baseline, 6 and 12 months, participants (N=535) were assessed for DED symptoms using Ocular Surface Disease Index (OSDI) and signs using conjunctival staining, corneal staining, tear breakup time (TBUT), Schirmer's testing, meibomian gland dysfunction, and tear osmolarity. Quality of life was evaluated using the Short Form Health Survey (SF-36), consisting of Physical Component Summary (PCS) and Mental Component Summary (MCS). Spearman correlation coefficients (rho) were used to evaluate correlations between the severity of DED and SF-36. At baseline, Worse DED symptoms indicated by higher OSDI total score were correlated with worse PCS (rho=-0.13, P=0.002) and MCS (rho=-0.09, P=0.03) of SF-36. The worse vision-related function was correlated with a worse PCS score (rho=-0.18, P<0.0001), and worse ocular symptoms were correlated with a worse MCS score (rho=-0.15, P<0.001). More severe DED signs including corneal staining (rho=-0.22, P<0.001), Schirmer test (rho=0.11, P=0.01), TBUT (rho=0.14, P<0.001), and tear osmolarity (rho=-0.12, P=0.02) were correlated with worse PCS score but were not correlated with MCS score (P≥0.39). ln longitudinal analysis, only worsening of ocular symptoms was significantly correlated with worsening of MCS score (rho=-0.09, P=0.04). In patients with moderate-to-severe DED, there were significant yet weak correlations between dry eye severity of symptoms/signs and physical or mental components of SF-36. Healthcare professionals should offer DED symptom relief and support for the emotional and practical challenges in their daily lives.

Surgicogenomics: The Role of Genetics in Deep Brain Stimulation in Parkinson's Disease Patients.

Parkinson's disease (PD) is the second-most common neurodegenerative disease, affecting 1% of people aged over 60. Currently, there is only symptomatic relief for PD patients, with levodopa being the gold standard of PD treatment. Deep brain stimulation (DBS) is a surgical option to treat PD patients. DBS improves motor functions and may also allow a significant reduction in dopaminergic medication. Important parameters for DBS outcomes are the disease duration, the age of disease onset, responsiveness to levodopa and cognitive or psychiatric comorbidities. Emerging data also highlight the need to carefully consider the genetic background in the preoperative assessment of PD patients who are candidates for DBS, as genetic factors may affect the effectiveness of DBS in these patients. This review article discusses the role of genetics in DBS for PD patients, in an attempt to better understand inter-individual variability in DBS response, control of motor PD symptoms and appearance of non-motor symptoms, especially cognitive decline.

Hyperelastic material models for simulating deformation of silicone ring pessaries

Pessaries are removable gynecological prosthetic devices that provide mechanical support for temporary or long-term symptom relief of pelvic floor disorders, such as pelvic organ prolapse and stress urinary incontinence. To date, limited mechanical tests have been performed on physical pessary designs to characterize their behaviour under load; however, custom pessary manufacturing is expensive and time consuming. As an alternative, finite element (FE) modeling can provide detailed numerical insight into the response of a pessary design under load but to date has seen limited application, with little data available for pessary silicone materials. This study aimed to identify hyperelastic material models for two silicone materials used in custom pessary cocoon moulded manufacturing towards FE analysis of ring with support (RWS) pessaries. It was hypothesized that hyperelastic material models could be identified to capture the force and deformation response of multiple RWS sizes under different boundary conditions and silicone materials (Shore 60A and 40A). To understand the material characteristics of pessary silicone, uniaxial tension and compression tests were performed then the experimental data was fit with Mooney-Rivlin (MR) material models. To ensure the material models characterize the pessary behaviour, data from mechanical tests representing the RWS pessary folding and modified 3-point bending were compared to FE recreations (FEBio) of the same tests with the MR materials applied to the pessaries. The FE model results demonstrated good agreement in the force-displacement response for the fold and 3-point bending models for different pessary sizes and silicone stiffnesses. This work demonstrates the hyperelastic material models’ efficacy and will enable future studies to improve biomechanical analysis of silicone pessary designs.

Arthroscopic Repair of Extruded Meniscus Tears: Impact on Symptom Relief and Functional Improvement - A 2-Year Follow-Up Study.

BACKGROUND This retrospective study from a single center in Turkey aimed to evaluate 2-year outcomes of 21 patients undergoing knee arthroscopic repair of extruded meniscus tears without root tear. MATERIAL AND METHODS The retrospective study comprised 21 individuals who underwent arthroscopic extruded meniscus repair and were followed up for at least 2 years. The study analyzed the meniscus extrusion amounts in preoperative and postoperative MRI scans, the Kellgren-Lawrence stages in knee radiographs, and the Lsyhom and The International Knee Documentation Committee (IKDC) scores of the included patients. RESULTS In this study, the repair operation extrusion levels were 3.30 mm from 4.01 mm preoperatively (P<0.001). After the repair, there was a significant increase in the Lsyhom and IKDC scores (P<0.001). According to the Kellgren-Lawrence scale, 12 patients were evaluated as stage 0, 6 patients as stage 1, and 3 patients as stage 2. According to the radiographs taken at the last follow-up, 2 patients progressed from stage 0 to stage 1, 2 patients progressed from stage 1 to stage 2, and 1 patient progressed from stage 2 to stage 3. CONCLUSIONS Arthroscopic treatment of extruded meniscus tears can enhance functional status and increase patients' functional status. Nevertheless, the absence of successful centralization extruded meniscus tears. This study discovered that radiological extrusion did not diminish beyond the critical threshold of 3 mm, which is associated with the development of osteoarthritis. This highlights the necessity of taking these elements into account when devising a treatment plan.

Mechanisms and treatment of pulmonary arterial hypertension.

Substantial progress has been made in the management of pulmonary arterial hypertension (PAH) in the past 25 years, but the disease remains life-limiting. Established therapies for PAH are mostly limited to symptomatic relief by correcting the imbalance of vasoactive factors. The tyrosine kinase inhibitor imatinib, the first predominantly non-vasodilatory drug to be tested in patients with PAH, improved exercise capacity and pulmonary haemodynamics compared with placebo but at the expense of adverse events such as subdural haematoma. Given that administration by inhalation might reduce the risk of systemic adverse effects, inhaled formulations of tyrosine kinase inhibitors are currently in clinical development. Other novel therapeutic approaches for PAH include suppression of activin receptor type IIA signalling with sotatercept, which has shown substantial efficacy in clinical trials and was approved for use in the USA in 2024, but the long-term safety of the drug remains unclear. Future advances in the management of PAH will focus on right ventricular function and involve deep phenotyping and the development of a personalized medicine approach. In this Review, we summarize the mechanisms underlying PAH, provide an overview of available PAH therapies and their limitations, describe the development of newer, predominantly non-vasodilatory drugs that are currently being tested in phase II or III clinical trials, and discuss future directions for PAH research.

Transorbital puncture for the treatment of cavernous sinus dural arteriovenous fistulas.

Endovascular embolization of carotid-cavernous sinus dural arteriovenous fistulas (CCFs) is most commonly performed via a transfemoral-transvenous approach. Surgical cut-down of the superior ophthalmic vein is an alternative, well-described route. When these prove inaccessible, a transorbital approach can be used to reach the fistula. We describe the recent experience- including indications, surgical technique, radiological findings and post-operative outcomes- in Melbourne of a series of patients in whom a percutaneous, transorbital direct puncture of the cavernous sinus enabled successful embolization of dural arteriovenous fistulas. Each of three patients achieved successful embolization of their CCFs via a transorbital puncture. Post-operatively, all patients experienced symptomatic relief with complete resolution of clinical signs secondary to their CCFs. When angioarchitecture does not allow endovascular access, transorbital puncture of carotid-cavernous sinus dural arteriovenous fistulas can be a safe and effective technique. This report supports its success and low complication rate.

Tibial Tubercle Osteotomy: Indications, Outcomes, and Complications.

The tibial tubercle osteotomy (TTO) is a versatile surgical technique used to treat a range of patellofemoral disorders, including patellar instability, painful malalignment, focal chondral defects, and patellar maltracking that have failed conservative therapies. TTO is a personalized procedure that can be tailored to the pathoanatomy of the patient based on physical examination and imaging. The complication rate associated with TTO strongly depends on the indication for surgery, the severity of the patient's condition, and the surgical approach. Despite the literature on TTO, to our knowledge, nosingle source has addressed the indications, techniques, outcomes, and complications of this procedure. The purpose of this article is to serve as such avaluable resource. Highlights from recent studies we would like to emphasize are two-fold. First, maintaining a distal cortical hinge yields lower complication rates than osteotomies involving complete tubercle detachment with classic or standard techniques. Second, based on current evidence, TTO consistently provides symptomatic relief, and most patients can return to work or sport at their pre-operative level within 3 and 6months, respectively. TTO is a personalizable surgical technique that may be utilized for multiple patellofemoral disorders and is associated with good outcomes.

Evaluating the protective effect of dapsone on experimental osteoarthritis models induced by MIA in male rats.

Osteoarthritis, a degenerative condition that results in significant morbidity, is typically managed with treatments aimed at symptom relief rather than addressing the underlying degeneration. Dapsone, recognized for its anti-inflammatory, antioxidant, antiexcitotoxic, and antiapoptotic properties, has demonstrated promising effects in various neurodegenerative diseases. This study explores the potential of dapsone to mitigate articular destruction, inflammation, and pain in rat models of osteoarthritis. Osteoarthritis was induced in rats by injecting MIA into the right knee joint. Dapsone was then administered intraperitoneally at 5, 10, or 20mg/kg every 2 days for 2 weeks. Behavioural tests were done on days 0, 7, and 14. On day 14, the articular cartilage was histologically analysed using H&E staining. Serum levels of NF-kB, IL-1β, and TNF-α were evaluated by ELISA. Dapsone effectively reduces pain, inflammation, and articular cartilage damage in osteoarthritis. Specifically, it improves mechanical allodynia and thermal hyperalgesia, reduces inflammatory markers (TNF-α, IL-1β, and NF-κB), and protects against cartilage destruction and chondrocyte loss, with the most significant effects at 20mg/kg. Dapsone effectively prevents pain, inflammation, and cartilage damage in osteoarthritis rats, suggesting its potential as a therapeutic option for managing osteoarthritis.

Physicians' knowledge, attitudes, and practices regarding fibromyalgia: A systematic review and meta-analysis of cross-sectional studies.

The diagnosis, etiology, and optimal management of fibromyalgia remains contentious. This uncertainty may result in variability in clinical management. We conducted a systematic review and meta-analysis of cross-sectional studies examining physicians' knowledge, attitudes, and practices regarding fibromyalgia. We searched MEDLINE, Embase, and PubMed from inception to February 2023 for cross-sectional surveys evaluating physicians' attitudes toward, and management of, fibromyalgia. Pairs of independent reviewers conducted article screening, data extraction, and risk of bias assessment in duplicate. We used random-effects meta-analysis to pool proportions for items reported by more than one study and the Grading of Recommendations Assessment, Development, and Evaluation approach to summarize the certainty of evidence. Of 864 citations, 21 studies (8904 participants) were eligible for review. Most physicians endorsed fibromyalgia as a distinct clinical entity (84%; 95% confidence interval [CI], 74-92), and half (51%; 95% CI, 40-62) considered fibromyalgia a psychosocial condition. Knowledge of formal diagnostic criteria for fibromyalgia was more likely among rheumatologists (69%, 95% CI, 45-89) versus general practitioners (38%, 95% CI, 24-54) (P = .04). Symptom relief was endorsed as the primary management goal by most physicians (73%, 95% CI, 52-90). Exercise, physiotherapy, antidepressants, nonsteroidal anti-inflammatory drugs, and non-opioid analgesics were most endorsed for management of fibromyalgia, but with wide variability between surveys. Opioids and most complementary and alternative interventions (e.g., homeopathy, chiropractic, and massage) received limited endorsement. There is moderate certainty evidence to suggest that physicians are divided regarding whether fibromyalgia is a biomedical or psychosocial disorder. Physicians typically prioritize symptom relief as the primary goal of management, and often endorse management with exercise, non-opioid analgesics, nonsteroidal anti-inflammatory drugs, antidepressants, and physiotherapy (moderate to high certainty evidence); however, important practice variation exists.

Oculomotor nerve palsy caused by imidacloprid at initial diagnosis: A case report.

Amid the pervasive deployment of imidacloprid, the incidence of poisoning from this compound has risen markedly. Those afflicted with imidacloprid poisoning typically exhibit symptoms ranging from headaches, dizziness, nausea, and abdominal pain, to impaired consciousness and breathlessness, yet instances of ocular paralysis induced by this toxin have not previously been documented. When the pesticide spray inadvertently made contact with the patient's eyes, they were seared with a burning sensation and discomfort. Subsequent to this incident, on the second day, the individual began to experience diplopia in the right eye and found it arduous to elevate his eyelids, indicating a challenge in achieving full extension. Based on the medical history, symptoms, and signs, the patient was diagnosed with oculomotor nerve palsy caused by imidacloprid. The treatment involved intravenous dexamethasone to reduce inflammatory response in the eye tissue; oral pantoprazole enteric-coated tablets to suppress acid production and protect the stomach; Xuesaitong administered intravenously to improve blood supply to the eye and promote metabolism of toxins; vitamin C, cobamamide, and vitamin B1 for nerve nutrition and antioxidant effects; local application of tobramycin-dexamethasone eye drops for anti-inflammatory purposes; and repeated flushing of the conjunctival sac with saline. Finally, the patient improved and was discharged. After active treatment, the patient finally improved diplopia and ptosis. This report marks the first documentation of oculomotor nerve palsy induced by imidacloprid, featuring diplopia, and blepharoptosis without substantial limitation of ocular motility. Following therapeutic intervention, the patient showed marked improvement and was discharged from the hospital, providing a point of reference for the treatment of analogous cases in future clinical practice. It also serves as a reminder for the public to take appropriate precautions when using imidacloprid.

Enki’s Seven Sages (Adapa/Oannes and the Apkallu): Humanity’s Cosmic Guardians

In contrast to the cruel and militant gods, who treated humans as pawns in their power struggle, Enki is remembered not just as a benevolent god who saved the human race from extermination, but who also imparted knowledge. Especially scholarly disciplines like divination, astrology, astronomy, lamentation and exorcism were considered a revelation by Enki. The Catalogue of Texts and Authors attests that a handbook of medical symptoms comes “of the mouth of Ea”, “Adapa wrote them down at his dictation.” Enki was helped by his Seven Sages – the apkallu (Adapa being the main one) – the cosmic guardians who disseminated his knowledge, and were remembered as teachers of humankind and laying the foundation of civilization. According to Berossus, “from that time nothing further has been discovered.” Sometime around the Flood they disappeared, descending to the abode of Enki. This transition is reflected in the change from semi-divine sages or culture-heroes (apkallu) to scholars (ummanu).

The effectiveness and safety of the anti gastroesophageal reflux system in the treatment of gastroesophageal reflux disease: a single center study of 23 cases

Objective: To evaluate the safety and efficacy of domestically produced magnetic sphincter augmentation (MSA) for gastroesophageal reflux disease. Method: This study is a prospective cohort study. Patients with typical heartburn and reflux symptoms (at least partial response to proton pump inhibitors), abnormal esophageal acid exposure and normal esophageal peristalsis were included, prospectively in the Department of Gastroesophageal Surgery, Rocket Force Characteristic Medical Center from June 2019 to September 2022. Patients with hiatal hernia >2 cm and severe esophagitis were excluded. The MSA was wrapped around the distal esophagus after esophageal hiatus repair by laparoscopy. A postoperative questionnaire survey was conducted to assess the relief of symptom, complications, the discontinuation rate of proton pump inhibitor, and surgical satisfaction. Gastroscopy, high-resolution esophageal pressure measurement, and pH value impedance monitoring were also reviewed. The pre- and postoperative rates were compared using the McNeinar χ2 test. Result: Currently, 23 patients with gastroesophageal reflux disease were enrolled and underwent MSA surgery. There were 20 males and 3 females, aged (M (IQR)) 48 (14) years (range: 25 to 64 years). All cases were successfully implanted with MSA. Subjective indicators were followed for 17 (18) months (range: 14 to 53 months), while objective indicators were followed for 17 (1) months (range: 12 to 23 months). The postoperative gastrointestinal and extraesophageal symptom scores showed a significant decrease compared to preoperative levels as follows: the degree of subjective relief of overall digestive symptoms was 90 (20)% (range:0~100%), the degree of subjective relief of overall respiratory symptoms was 100(10)% (range: 10%~100%), the overall satisfaction rate was 83% (19/23), the proton pump inhibitor discontinuation rate was 70% (16/23). The proportion of esophagitis has decreased from 44% (10/23) to 9% (2/23) (κ=0.169, P=0.039), The Hill grade of gastroesophageal valve morphology improved from 1 case of grade Ⅰ, 5 cases of grade Ⅱ, 10 cases of grade Ⅲ, and 7 cases of grade Ⅲ preoperative to 22, 1, 0, and 0 cases postoperative. The proportion of lower esophageal sphincter pressure below normal has decreased from 70% (16/23) to 35% (8/23) (κ=0.170, P=0.012). There were 21 patients who restored normal esophageal acid exposure. Eleven patients had mild long-term dysphagia, but it didn't affect their daily life. No postoperative device migration, erosion, or secondary surgical removal occurred. Conclusions: Laparoscopic implantation of the MSA device was safe and well tolerated. It can effectively control the symptoms of gastroesophageal reflux disease, reduce medication, restore normal cardia morphology and function, and esophageal acid exposure. The main postoperative complication was dysphagia, but it was relatively mild.

Skin complications during iron chelation therapy for beta-thalassemia: overview and treatment approach.

Thalassemia is an inherited genetic disorder of hemoglobin that affects a large population worldwide, and it is estimated that between 50,000 and 60,000 infants with thalassemia are born each year. The most common treatment for thalassemia is blood transfusion, which leads to iron overload. This in itself is a serious clinical condition, and is commonly managed with iron chelation therapy. However, iron chelators can cause various skin complications, including hyperpigmentation, skin rash, itching, and photosensitivity. These skin side effects can impact patients' quality of life. Therefore, this article provides a comprehensive overview of skin complications caused by iron chelators, along with a proposed comprehensive approach to their management in patients with beta-thalassemia. Key strategies include patient education, regular skin assessment, sun protection measures, symptomatic relief with topical corticosteroids and antihistamines, and consideration of treatment modification if severe complications occur. Collaboration between hematologists and dermatologists, along with psychological support and regular follow-up, is an essential component of this multidisciplinary approach. By implementing these strategies, healthcare providers can optimize skin care for patients with beta-thalassemia treated with iron chelators and improve their quality of life.

Effect of Cellular Dosage of Bone Marrow Aspiration Concentrate on the Radiological Outcomes in Knee Osteoarthritis: A Phase I Dose-Escalation Study.

Knee osteoarthritis(KOA), a chronic degenerative disease, significantly impairs quality of life due to pain and mobility limitations. Traditional treatments focus on symptom management without addressing the underlying disease progression, leading to a growing interest in regenerative medicine approaches. Bone marrow aspirate concentrate (BMAC), rich in mesenchymal stem cells and growth factors, has shown potential for cartilage repair and symptom relief in KOA. Despite promising outcomes, the optimal BMAC dosage for knee OA treatment remains undetermined. This study aims to evaluate the radiological outcomes of varying BMAC dosages in knee OA treatment. This prospective controlled dose-escalation study involved 75 patients with early-stage knee OA, categorized into three groups based on BMAC dosage administered 10x106 cells (low-dose group), 50×106 cells (medium-dose group), or 100x106 cells (high-dose group). All the patients underwent a single intra-articular injection of BMAC and were monitored over a year. The primary outcomes include magnetic resonance observation of cartilage repair tissue (MOCART 2.0) score to assess the cartilage. We noted significant improvement in the overall MOCART score (p=0.027) and subchondral change sub-score (p=0.048) and defect filling sub-score (p=0.025) in the medium- and high-dose cohorts compared to the low-dose cohort at 1year follow-up. Although we noted positive correlation between the clinical and radiological outcome (r=0.43), we did not find any significant different in the clinical outcome between the treatment groups. BMAC for OA knee resulted in significant improvement in the radiological scores compared to the baseline. Medium and high doses of BMAC result in significantly higher radiological scores compared to low-dose BMAC at 1year. However, the radiological improvement did not translate into functional improvement, irrespective of the dosage administered at 1year. Further research is necessary on the long-term outcomes to understand and optimize the dosing strategy based on clinico-radiological results.

MRI-Guided Radiation Therapy for Splenomegaly: Clinical Experiences and Technical Tips

IntroductionSplenomegaly is a common manifestation in chronic lymphoid and myeloid malignancies. While splenectomy is the preferred treatment for symptomatic splenomegaly, it carries significant risks. Radiotherapy (RT) has traditionally been considered a palliative option. This study explores the use of Magnetic Resonance-Guided Radiotherapy (MRgRT) for splenic irradiation (SI) in patients with myelofibrosis (MFI) and myelodysplastic/myeloproliferative neoplasms (MDS/MPN). MethodsThis single-center retrospective analysis includes patients with MFI and MDS/MPN who underwent MRgRT SI between 2018 and 2022. Ten 1 Gy fractions were delivered to the PTV (spleen+3/5mm margin). An adaptive online/offline strategy has been used to reduce the dose to healthy organs. Dosimetric data and clinical outcomes, including pain relief, gastrointestinal symptoms, and hematological values, were assessed. ResultsTwelve patients completed SI without interruption, with supportive transfusions as needed for cytopenias. Pain and gastrointestinal symptoms relief was observed in most cases. The mean percentage reduction in spleen volume was 53.61%, with an average cranio-caudal extension reduction of 77.78%. Twenty-nine (24.2%) out of 120 fractions were online adapted and 14 (11.7%) were replanned offline. Non-hematological toxicities were not reported. At a median follow-up of 12.9 months, 6 patients died, while 9 patients underwent hematopoietic cell transplantation, with 6 of them surviving. ConclusionThis study demonstrates MRgRT SI feasibility in MFI and MDS/MPN patients, offering symptom relief and significant spleen volume reduction. Real-time setup verification and adaptive planning allowed for tailored treatment with reduced margins, minimizing healthy tissue exposure. Larger prospective studies with longer follow-up are needed to further validate its efficacy and safety.

ESR Essentials: image guided drainage of fluid collections-practice recommendations by the Cardiovascular and Interventional Radiological Society of Europe.

This ESR Essentials article intends to provide detailed, step-by-step, information on the role of imaging in the diagnosis, procedural management, and follow-up of patients with fluid collections. Evidence-based medicine recommendations for the positioning of percutaneous drainages and/or for diagnostic/therapeutic aspiration of fluid collections are provided. Although medical history, clinical symptoms, physical examination, and laboratory tests can raise suspicions regarding a collection, an imaging assessment is usually necessary for the diagnosis. Radiologists can easily identify fluid collections that are clinically suspected by using a wide range of imaging modalities, such as ultrasound, CT, MRI, and cone-beam CT. Consequently, these imaging methods (either alone or combined), can be used to aspirate the collection or for the placement of a drainage catheter. The choice of imaging technique to be used is influenced by the location of the collection, operator preference, size, and content of the collection. In addition, it is of utmost importance to underline the role of the interventional radiologist in the management and follow-up of patients with percutaneous drains, in collaboration with surgeons, clinicians, and diagnostic radiologists. KEY POINTS: Indications for percutaneous imaging-guided drainage are supported by clinical findings, laboratory tests, and pre-procedural imaging. Deciding between aspiration or drain insertion should follow patient assessment and fluid collection characterization. The interventional radiologist should be part of the entire patient care process including follow-up.

Role of aneurysmal hemodynamic changes in pathogenesis of headaches associated with unruptured cerebral aneurysms.

One symptom commonly associated with the presence of unruptured intracranial aneurysms is headache. In this study, the authors aimed to analyze factors associated with headaches among patients with intracranial aneurysms, with special consideration of hemodynamic parameters. The authors prospectively included 96 patients with 122 unruptured intracranial aneurysms. The authors obtained detailed medical history including current diseases and medications, as well as blood pressure values taken during hospitalization from the patients' medical records. The short-form McGill Pain Questionnaire was administered to each patient at admission and 3-6 months after the procedure to assess type and severity of headache. Based on imaging data, the authors obtained 3D reconstruction of each patients' aneurysm dome with feeding artery. The authors performed computational fluid dynamics analysis of blood flow through prepared models using OpenFOAM. Blood was modeled as Newtonian fluid, using the incompressible transient solver. Patient-specific internal carotid artery (ICA) blood velocity waves obtained with Doppler ultrasound were set as inlet boundary conditions. After performing simulation, the authors calculated the hemodynamic parameters of the aneurysm dome. A total of 30 patients (31.25%) reported having headaches. In multivariate logistic regression analysis, female sex (OR 2.81, 95% CI 2.51-4.86; p < 0.01), ICA aneurysm location (OR 7.93, 95% CI 5.51-8.52; p < 0.01), multiple aneurysms (OR 6.05, 95% CI 1.83-11.83; p = 0.02), mean dome blood velocity (OR 3.10, 95% CI 2.01-3.30; p < 0.01) and time-averaged wall shear stress (OR 1.18, 95% CI 1.47-2.72; p = 0.04) were independently associated with the presence of headache. Additionally, 17 patients (56.67%) reported complete relief of symptoms after the procedure. In multivariate logistic regression analysis, the mean blood flow in the ICA was independently associated with complete resolution of headaches after aneurysm treatment (OR 2.32, 95% CI 1.57-3.28; p < 0.01). Hemodynamic parameters of intracranial aneurysms might be associated with headaches and their relief after aneurysm treatment.

Clinical impact of esophageal muscle thickness on peroral endoscopic myotomy patients.

Peroral endoscopic myotomy (POEM) is a standard procedure for achalasia, an esophageal motility disorder, characterized by a thickened lower esophageal sphincter muscularis propria (LEMP). Visualization of this anatomical stratification has been made possible by the advent of endoscopic ultrasound (EUS). However, the effect of LEMP thickness on treatment outcomes remains unclear. The objective of this study was to investigate whether LEMP thickness affects treatment response post-POEM. This was a single-center, prospective cohort study of patients who underwent POEM between 2014 and 2021. Patients who underwent EUS to evaluate the LEMP before POEM were included in the study. We divided the patients into two groups according to muscle thickness measured by EUS (≥ 2.80mm; group 1, < 2.80mm; group 2). The pre- and post-procedural clinical parameters were compared between the two groups. Among 278 patients, 189 were enrolled. There were no significant differences in the pre- and post-Eckardt scores, integrated relaxation pressure, and distensibility index between the two groups divided by muscle thickness. Furthermore, there was no statistically significant difference in symptom recurrence, as measured by an Eckardt score > 3, post-procedural complications, or post-POEM GERD symptoms. However, patients with thicker lower esophageal sphincter muscle showed a greater decrease in Eckardt scores (ΔES ≥ 3) which was statistically significant (P = 0.002). POEM is an effective and safe treatment method for achalasia, regardless of LES muscle thickness. There was a statistically significant difference in the decrease of Eckardt scores of 3 or greater (ΔES ≥ 3) after POEM in the thicker LEMP group suggesting greater alleviation of symptoms in POEM patients with thicker lower esophageal muscle.

Vitamin D Supplementation in Congenital Ichthyosis: A Case Series.

Ichthyosis is a group of genetic keratinization disorders characterized by excessive scaling that is associated with hyperproliferative epidermis and/or cellular retention. Whereas normal outer epidermis thickness is 25 μm, it can be 10-fold greater in patients with ichthyosis. As a result, photoactivation of 7-dehydrocholesterol is impaired, causing systemic vitamin D deficiency.In this case series, 25 patients with congenital ichthyosis with vitamin D deficiency (<10 ng/mL) were supplemented with 60,000 IU of vitamin D3 for 10 days followed by daily allowance of 400 to 600 IU of vitamin D3 and 40 mg/kg per day of elemental calcium. The authors assessed improvement in cutaneous scaling and body and tested patients' blood and urine samples at day 1, day 10, 1 month, and 3 months. They also documented patients' Dermatology Life Quality Index score before and after treatment.All patients had normal vitamin D levels; supplementation was discontinued for two patients who reached a level of 100 ng/mL within 10 days. Subjective improvement of symptoms (dryness of the skin, allergic rhinitis, tightness of the skin, and scaling) was observed by both the provider and the patients. There was remarkable improvement in symptoms of severe ichthyosis such as lamellar ichthyosis (tightness of the skin and scaling). Marked improvement in Dermatology Life Quality Index score was also noted.This case series demonstrated remarkable symptomatic relief with vitamin D supplementation in patients with congenital ichthyosis; however, additional research should be conducted with larger sample sizes to support these findings.
