Giant Epididymal Cyst in the Right Testicle: Case Report and Literature Review.

Introduction: Cystic intratesticular lesions can occur in the second and fourth decades of life and are typically identified via ultrasound. Testicular cysts, usually under 2 cm, result from epididymal-lymphatic obstruction or hormonal changes. Larger lesions with sperm and lymphocytes are spermatoceles. Epididymal cysts are asymptomatic but can cause discomfort or pain, sometimes requiring surgery. Clinical case: A 38-year-old male with no chronic diseases presented with a giant tumor in the right testicle, experiencing pain and hypersensitivity. Physical examination and ultrasound revealed an irregular, painful testicular tumor and a right epididymal cyst. A right epididymal tumor excision was performed successfully. Discussion: Testicular cysts are benign and represent 20-40% of benign testicular tumors. They may arise due to idiopathic, infectious, or traumatic causes with no established risk factors. Diagnosis is often incidental and involves physical examination and imaging techniques like ultrasound. Management is conservative for asymptomatic cases, while symptomatic cases may require surgical intervention that involves careful separation of the cyst from the adhered area. Conclusion: An epididymal cyst is a common pathology in males worldwide, occupying up to 40% of the masses in the testes at the time of a urological assessment. It is a collection at the testicular level of hyaline content and usually measures < 2 cm. They are generally asymptomatic, but when their size exceeds 2 cm or causes symptomatology, it is important to know the therapeutic options that can be offered to patients. In the case of our patient, as it is an epididymal cyst with a diameter of 5 cm and with additional symptomatology, the ideal management was surgical resection, showing adequate evolution in the postoperative follow-up.

Immunohistochemical expression of Fibrillin-1 in idiopathic epiretinal membranes.

To investigate the expression patterns of Fibrillin-1 in idiopathic epiretinal membranes (iERM) and identify Fibrillin-1-secreting cells. iERM samples were collected via standard 27-gauge vitrectomy and subsequently subjected to flat-mount immunohistochemistry with double staining for the following markers: Fibrillin-1, glial acidic fibrillary protein (GFAP), cellular retinaldehyde-binding protein (CRALBP), retinoid isomerohydrolase RPE65 (RPE65), and α-smooth muscle actin (α-SMA). Fibrillin-1 was detected throughout the iERM. The colocalization of Fibrillin-1 with α-SMA, CRALBP, and RPE65 suggested that myofibroblasts and retinal pigment epithelial (RPE) cells secreted Fibrillin-1. The lack of colocalization between GFAP and Fibrillin-1 indicated that GFAP-positive glial cells did not secrete Fibrillin-1. The colocalization of CRALBP and RPE65 with α-SMA indicated the transformation of RPE cells into myofibroblasts. This suggested that RPE cells transformed into myofibroblasts and secreted Fibrillin-1. The lack of colocalization between GFAP and α-SMA implied that GFAP-positive glial cells did not express α-SMA. Fibrillin-1 is widely distributed in iERMs, and myofibroblasts were the primary sources of Fibrillin-1 secretion. Additionally, during their transformation into myofibroblasts, RPE cells secreted Fibrillin-1. GFAP-positive glial cells did not express α-SMA nor secrete Fibrillin-1. What is known Idiopathic epiretinal membranes area common cause ofvisual acuity and quality impairment. The proteinand cell components ofidiopathic epiretinal membrane exhibit diversity. What is new Fibrillin-1 is present throughout the idiopathic epiretinal membrane. Myofibroblasts are the most important source of Fibrillin-1 secretion. Retinal pigmentepithelial cells also secreteFibrillin-1 when transforming into myofibroblast. Glial cells donot transform to myofibroblast and donot secrete Fibrillin-1.

12460 Bilateral Parietal Thinning: A Rare Condition Of Unclear Etiology

Abstract Disclosure: T.L. Madsen-Barbosa: None. M. Cheikh: None. I. Marcano: None. Background: Bilateral parietal bone thinning (BPT) is an infrequent and often underdiagnosed condition characterized by the external thinning of the skull's parietal bone. The pathophysiology is unclear, but some studies suggest a link to osteoporosis. We present a case of osteoporosis diagnosed on evaluation of BPT. Case Description: A 77-year-old woman with a history of chronic kidney disease (CKD stage IV) and type 2 diabetes was referred to the Bone Health Clinic for evaluation of low bone density. She initially presented to Neurosurgery clinic for evaluation of head indentations. A dual energy x-ray absorptiometry (DEXA) scan showed values in osteopenia range (left total hip bone mineral density (BMD) 0.678 and T-score of -2.2, left femoral neck BMD 0.272 and T-score of -1.6, and left 33% radius BMD 0.577 and T-score of -2.0), leading to the referral. The patient reported painless indentations in the parietal bones that had been progressing for four years, with no history of head trauma, inflammatory disease, or prolonged steroid use. A head computed tomography (CT) scan showed symmetric thinning of the skull’s parietal bones, with an average thickness of 2.34 mm (compared to 5.1 mm four years earlier). Review of prior images also revealed a T11 compression fracture on spine X-ray from 2019. Laboratory tests showed elevated parathyroid hormone (PTH) 155 pg/mL (reference range 15-65 pg/mL), low vitamin D 25-OH 10.6 ng/mL (reference range 30-100 ng/mL), elevated alkaline phosphatase 142 units/L (reference range 46-116 units/L), and high creatinine level 2.7 mg/dL (reference range 0.5-0.8 mg/dL), other laboratory tests were normal. After discussion with the patient and Nephrology, Denosumab therapy along with Calcium and Vitamin D supplementation were started in November 2023. The patient continues the treatment with antiresorptive medication every 6 months and head CT scan to monitor the skull thinning changes. Discussion: BPT is rare, with only approximately 150 cases reported. Crucial aspects such as its etiology, pathophysiology, treatment, and prognosis remain unknown. It can result from various conditions like trauma, systemic mastocytosis, diabetes mellitus, hereditary diseases, or idiopathic causes and mainly affects women of advanced age. Osteoporosis is suggested as a possible cause based on histological findings on prior studies that propose BPT may result from osteoporosis-induced decreased bone formation rather than increased bone destruction. The reason for excessive bone resorption in the skull of osteoporotic patients remains unclear. Our case highlights progressive and symmetric BPT possibly related to systemic conditions like osteoporosis, with a focus on treatment options. Conclusion: This case sheds light on the clinical presentation, imaging findings, pathogenesis, and treatment options for the rare condition of bilateral parietal bone thinning.

Partial right gonadal vein thrombosis after uterine fibroid embolization

Gonadal vein thrombosis (GVT) is a very rare complication of uterine fibroid embolization. The risk factors for GVT include pregnancy, especially after caesarean-section, oral contraceptive use, underlying malignancy, any pelvic surgery including embolization procedures, pelvic inflammatory disease, inflammatory bowel disease and idiopathic causes. We report a case of a patient who underwent extensive uterine fibroid embolization and presented to the Emergency Department within twenty-four hours, with fever, and severe abdominal pain. Computed tomography of the abdomen and pelvis with intravenous (IV) contrast confirmed a partial right gonadal vein thrombosis. After extensive work up, and no alternative causes found, a diagnosis of procedure related GVT was made. After review of the literature and discussion with hematology consultants, she was started on anticoagulant therapy. Her symptoms resolved and she remained on anticoagulation for a duration of three months

Overview of Unilateral and Bilateral Pediatric Facial Paralysis: Workup, Treatment, and Frontiers.

Pediatric facial nerve paralysis can present significant challenges based on its various etiologies, unique approach to treatment options, and overall outcomes. It can impact both the child and parent when regarding function, appearance, and psychosocial implications. The etiology of facial nerve palsy can include congenital, traumatic, iatrogenic, and idiopathic causes. In some, the paralysis is transient while others have permanent loss of function. A thorough evaluation and differential diagnosis are essential to guide treatment planning. The purpose of this paper is to review facial paralysis in children with a focus on surgical management.

Differentiated metabolomic profiling reveals plasma amino acid signatures for primary glomerular disease

Primary glomerular disease (PGD) is an idiopathic cause of renal glomerular lesions that is characterized by proteinuria or hematuria and is the leading cause of chronic kidney disease (CKD). The identification of circulating biomarkers for the diagnosis of PGD requires a thorough understanding of the metabolic defects involved. In this study, ultra-high performance liquid chromatography–tandem mass spectrometry was performed to characterize the amino acid (AA) profiles of patients with pathologically diagnosed PGD, including minimal change disease (MCD), focal segmental glomerular sclerosis (FSGS), membranous nephropathy, and immunoglobulin A nephropathy. The plasma concentrations of asparagine and ornithine were low, and that of aspartic acid was high, in patients with all the pathologic types of PGD, compared to healthy controls. Two distinct diagnostic models were generated using the differential plasma AA profiles using logistic regression and receiver operating characteristic analyses, with areas under the curves of 1.000 and accuracies up to 100.0% in patients with MCD and FSGS. In conclusion, the progression of PGD is associated with alterations in AA profiles, The present findings provide a theoretical basis for the use of AAs as a non-invasive, real-time, rapid, and simple biomarker for the diagnosis of various pathologic types of PGD.

A Unique Comprehensive Model to Screen Newborns for Severe Combined Immunodeficiency-An Ontario Single-Centre Experience Spanning 2013-2023.

Severe combined immunodeficiency (SCID) is a life-threatening genetic disorder caused by critical defects of the immune system. Almost all cases are lethal if not treated within the first two years of life. Early diagnosis and intervention are thus essential for improving patient outcomes. In 2013, Ontario became the first Canadian province to perform newborn screening (NBS) for SCID by T cell receptor excision circles (TRECs) analysis, a surrogate marker of thymic function and lymphocyte maturation. This retrospective study reports on nearly 10 years of NBS for SCID at a quaternary referral centre. From August 2013 to April 2023, our centre's densely populated catchment area flagged 162 newborns with low TRECs levels, including 10 cases with SCID. Follow-up revealed other causes of low TRECs, including non-SCID T cell lymphopenia (secondary/reversible or idiopathic causes, and syndromic conditions) and prematurity. A small number of cases with normal repeat TRECs levels and/or T cell subsets were also flagged. Province-wide data from around this period revealed at least 24 diagnosed cases of SCID or Leaky SCID. This is the first report of NBS outcomes in a Canadian province describing the causative genetic defects, and the non-SCID causes of a positive NBS for SCID.

Prevalence and Risk Factors for Portal Cavernoma in Adult Patients with Portal Vein Thrombosis.

Portal vein thrombosis (PVT) represents a restriction or occlusion of the portal vein by a blood clot, which can appear in liver cirrhosis, inherited or acquired thrombophilia, malignancies, abdominal infection, abdominal inflammation, and injury to the portal vein; it can evolve to local venous extension, recanalization, or portal cavernoma (PC). This research represents an observational study of patients admitted with a diagnosis of PVT between January 2018 and December 2022. We assessed the rate of and risk factors for PC. In total, 189 patients with PVT were included; the rate of PC was 14.8%. In univariate and multivariate analysis, the main risk factors for the presence of PC were etiology (thrombophilia, myeloproliferative disorders, local inflammatory diseases, and idiopathic causes), prior PVT, and complete versus incomplete or single-branch portal obstruction. In patients with superior mesenteric vein (SMV) thrombosis, distal obstruction was more prone to PC than proximal obstruction. The main predictive factors were etiology, prior PVT, complete PVT obstruction, and no prior non-selective beta-blocker (NSBB) use; in patients with SMV thrombosis, the distal extension was more significantly associated with the risk of PC. We propose a composite score for the prediction of PC which includes etiology, prior diagnosis of PVT, prior NSBB use, complete versus incomplete PVT, and distal versus proximal SMV thrombosis, with good accuracy (AUC 0.822) and an estimated sensitivity of 76.92% and specificity of 82.39% at a cut-off value of 4.

Role of Adjuvant Mitomycin C in The Endoscopic Treatment of Laryngotracheal Stenosis (Meta-Analytic Study)

Abstract Background Laryngotracheal stenosis is a life-threatening restriction in pulmonary ventilation. It is an umbrella term, including luminal compromise at the level of the larynx, subglottis, or trachea. Etiology of laryngotracheal stenosis is multifactorial. In adults and adolescents it is mostly acquired, where in children it may be acquired or congenital. Acquired laryngotracheal stenosis can result from previous intubation or tracheostomy, systemic disease, trauma, infection, or idiopathic causes. Historically, infectious etiology was common. Currently, laryngotracheal stenosis most frequently results from prolonged intubation or trauma from intubation itself. Objective To evaluate the effectiveness of topical Mitomycin C as an adjuvant treatment with the endoscopic management of laryngotreacheal stenosis. Patients and Methods The total number of patients in all the included studies was 454, 379 patients in MMC group and 75 patients in non-MMC group. Results This meta-analysis study showed that resolution (success) rate in MMC group was (68.7%) and there was a significant increase in resolution (success) rate in MMC compared to non- MMC group (p = 0.011) with the odds of being 5 times higher in MMC group (OR = 5.04). The Complications rate in MMC using patients was (4%). The result of this meta-analysis study showed that Mitomycin C is an effective and safe adjuvant in the endoscopic treatment of laryngotracheal stenosis. However, this study included limitations. We recommend the need of more high quality prospective randomized controlled trials, two armed studies and further studies in the future to achieve stronger results. Conclusion We suggest that that Mitomycin C is an effective and safe adjuvant in the endoscopic treatment of laryngotracheal stenosis. However, this study included limitations. We recommend the need of more high quality prospective randomized controlled trials, two armed studies and further studies in the future to achieve stronger results.

Children with bicytopenia and pancytopenia – clinical picture, etiological spectrum, and outcome

Background: Children who develop cytopenias present with several etiological causes, posing diagnosis, and management difficulties for both physicians and pathologists. With these in mind, we assessed the clinical profile and etiology of children who attended a healthcare facility in South India with bicytopenia or pancytopenia. Aims and Objectives: (1) The primary objective of this study was to find out the clinical and etiological spectrum in children with bicytopenia and pancytopenia who were admitted to the Institute of Child Health and Research Center, Government Rajaji Hospital, Madurai. (2) The secondary objective of this study is to follow-up children with bicytopenia and pancytopenia to find out the outcome and prognosis. Materials and Methods: This study was in the Department of Pediatrics at the Government Rajaji Hospital in Madurai, Madurai Medical College’s Institute of Child Health and Research Center, which is where we carried out the study. Two hundred and sixty-four patients with bicytopenia and 36 patients with pancytopenia were included in this study. Once in 2 weeks, all children with bicytopenia and pancytopenia were assessed in our Saturday hematology outpatient clinics. Results: Fever was the most prevalent sign of both pancytopenia and bicytopenia in this investigation. Etiological variables among cases of pancytopenia, cancer, infections, non-infections, and idiopathic causes were recorded in 11%, 58%, 17%, and 14% of cases, respectively. Similarly, bicytopenia, malignancy, infections, non-infections, and idiopathic causes were found in 23%, 70%, 4%, and 3% of cases, respectively. According to the prognosis, 28%, 33%, 6%, and 33% of cases with pancytopenia recovered, passed away, were lost to follow-up, or were undergoing treatment, respectively. Similar to those individuals, 67%, 11%, 4%, and 18% of bicytopenia cases were treated, recovered, or lost to follow-up, respectively. Conclusion: In children, there is a wide etiological range of cytopenias. Infections and dangerous diseases like acute leukemia are among the reasons. The geographical location of the hospital, the frequency of malnutrition, and the regional presence of certain diseases such as malaria and enteric fever determine the causes reported in a hospital environment.

A prospective study on the causes of hyperbilirubinemia and its clinical markers in term and near-term newborns admitted to a tertiary care hospital in Patna, India

This study aimed to investigate the root causes, prognostic factors, and therapeutic strategies for neonatal hyperbilirubinemia among term and near-term infants admitted to the Neonatal Intensive Care Unit (NICU) at IGIMS, Patna. Furthermore, the research aimed to analyze the clinical progression of these infants throughout their NICU stay.Conducted within the NICU at IGIMS, Patna, Bihar, this study encompassed term and late preterm infants admitted with serum bilirubin levels exceeding 12 mg/dl. The primary focus was on identifying risk factors, etiological factors, and the clinical profile of these infants during their NICU tenure.The study examined birth weight distribution and concurrent medical conditions. Parameters included the initiation of phototherapy based on bilirubin levels and treatment methodologies. Out of the 210 infants studied, 27.14% and 47.62% weighed between 2001 and 2500 grams. The most prevalent causes were physiological (129 cases), fetal prematurity (30 cases), birth asphyxia (7 cases), and prolonged labor (18 cases). Idiopathic causes were observed in 28 instances, ABO incompatibility in 7 cases, and Rh incompatibility in 7 cases. G6PD deficiency was identified once. At the commencement of phototherapy, 19.52% had bilirubin levels between 12 and 15 mg/dl, 58.57% between 15.1 and 18 mg/dl, 11.91% above 20 mg/dl, and 10% between 18.1 and 20 mg/dl.Physiological causes emerged as the most frequent contributors to neonatal hyperbilirubinemia, followed by septicemia and idiopathic factors. Infrequent causes included blood group incompatibility. Phototherapy was established as a cost-effective and efficient method for reducing bilirubin levels in neonatal jaundice. Exchange transfusion proved to be a safe therapeutic measure in cases of severe hyperbilirubinemia. Blood group incompatibility was the main determinant requiring exchange transfusion.

Evaluation of Quality of Life and Visual Outcomes in Children with Uveitis

This prospective study examines the impact of uveitis on children’s quality of life, focusing on visual outcomes and overall well-being. Thirty-two patients, primarily males, aged 6 to 16, were assessed at Mohamed VI University Hospital in Marrakech. Anterior uveitis was the most common type, with various etiologies including juvenile idiopathic arthritis and idiopathic causes. Results highlighted a substantial negative impact on quality of life, evidenced by academic difficulties, psychological distress, and physical limitations. The findings emphasize the necessity of comprehensive patient care and personalized follow-up to address the multifaceted challenges posed by pediatric uveitis.

Pulmonary Arterial Hypertension (PAH) Group 1 (Part A): Overview, Classification, Clinical Subsets, and Workup

Abstract: Pulmonary hypertension is a rare, progressive disease characterized by increased pulmonary arterial pressure and right ventricular failure due to pulmonary vascular remodeling. The disease definition and management have evolved over time. The 6th WSPH now defines it as a mean pulmonary arterial pressure >20mmHg, while recent ESC/ERS guidelines recommend lowering the threshold for pulmonary vascular resistance to 2WU. : Understanding of the disease has improved through registries, classifying it into five distinct groups with similar histology, pathophysiology, and therapeutic approaches. These groups include PAH, with heritable and idiopathic causes, as well as various clinical subsets involving connective tissue disease, HIV, portopulmonary hypertension, congenital heart disease, and schistosomiasis. Long-term responders to calcium channel blockers, PAH with venous/capillaries involvement, and persistent PH of newborns are categorized under Group 1, now re-classified as IPAH. : A comprehensive workup for suspected patients includes various tests like electrocardiogram, pulmonary function testing, autoimmune workup, HIV testing, echocardiogram, right heart catheterization, and cardiopulmonary exercise testing. : This review emphasizes the disease's definition and epidemiology, delving into each subset and providing updated workup guidelines. The subsequent article will focus on risk stratification and treatment strategies.

Gestion de la péricardite constrictive : à travers l’étude de 43 cas opérés

Chronic constrictive pericarditis is a rare condition characterized by clinical signs of right heart failure, due to the symphysis of the two pericardial leaflets.Our study focused on a retrospective analysis of 43 CCP surgery observations collected over an 11-year period (2003–2013).The mean age of the patients was 32 years; 65% were male; exercise dyspnea (95%) was the most frequent sign. Two main etiologies were observed: tuberculosis 58% and idiopathic causes 42%. All of our patients received a subtotal pericardectomy per median sternotomy, of which 95% had no cardiopulmonary bypass.

A vocal cord palsy caused by the uterine cancer metastatic tumor in the mediastinum revealed in a patient with a thyroid lesion: a case report and review of the literature

BackgroundThe main cause of vocal cord palsy (VCP) is idiopathic impairment of the recurrent laryngeal nerve (RLN). However, solid tumors along the pathway of the RLN can also impact the nerve’s function. We presented a patient with a thyroid lesion and VCP due to a bulky metastatic mass (uterine cancer) on the aortic arch field in the mediastinum. The report aims to show the significance of comorbid tumors in thyroid pathology and the importance of additional diagnostic methods in avoiding unnecessary surgeries. A patient’s lifetime and the outcome of the disease were also presented.Case presentationA 58-year-old Ukrainian woman with a hoarse voice, intermittent dry cough, and weakness was presented to an endocrine surgeon. Thyroid pathology included signs of hypothyroidism treated with Thyroxine 112.5 µg and a nodule in the left lobe. The lesion is located on the posterior aspect of the lobe, which could probably be a cause of RLN involvement. Fine needle aspiration biopsy (FNAB) was performed twice with Bethesda category 2 result. Fibrolaryngoscopy (FLS) revealed the median position of the left vocal cord. Idiopathic, laryngeal, and thyroid causes of the VCP were excluded. Additionally, the patient displayed her anamnesis of the endometrial clear cell carcinoma following hysterectomy, external beam radiation therapy, and chemotherapy. The mediastinal metastasis was revealed sixteen years later. A chest computed tomography (CT) with intravenous contrast was done. A bulky tumor was found right under the aortic arch. Subsequently, the voice complaints reduced significantly after 4 chemotherapy courses. Cancer progression had led to the appearance of lymph node metastases on the supraclavicular region. Following six months the 60-year-old patient had passed away.ConclusionA history of the disease should always be kept in mind when assessing a patient’s complaints. VCP in case of thyroid pathology and previous secondary malignancy may be caused by metastatic tumor anywhere along the RLN pathway. Such a rare case shows the importance of additional methods of examination which may avoid unnecessary thyroid surgeries.

Clinical features and outcome of 10 dogs with suspected idiopathic vestibular epilepsy.

In humans, vestibular epilepsy (VE) is described as focal seizures with transient signs of vestibular disease. In dogs, 2 cases of vestibular episodes, called vestibular paroxysmia, are reported. The objective of this study was to define the clinical features, phenotypical manifestation, and outcome of suspected VE in dogs. Ten dogs with recurrent vestibular episodes. Retrospective study. Medical records between 2009 and 2023 were reviewed, and dogs with a normal neurological examination, a history of transient signs of vestibular disease, absence of abnormalities detected on blood exams and brain magnetic resonance imaging (MRI) or computed tomography (CT), besides a minimum 10-month follow-up were included. Clinical improvement was defined as a ≥50% reduction in frequency or the cessation of clinical signs after the onset of antiseizure medications (ASMs). Pugs were the most prevalent breed (5/10; 50%). In 2 cases, additional generalized tonic-clonic (GTC) seizures were reported. MRI exam was performed in most cases (9/10; 90%), whereas 1 dog underwent a CT scan (1/10; 10%). Electroencephalography (EEG) was carried out in 3 dogs that showed interictal spikes in the fronto-temporal and fronto-parietal areas. All cases received ASMs, with clinical improvement in 10/10 dogs (100%). The presence of GTC seizures, EEG interictal spikes, and responsiveness to ASMs supported the hypothesis of an epileptic origin of vestibular episodes and thus the existence of VE in these dogs, with a presumed idiopathic cause and apparent favorable outcome.

UrethroNAV: the aetiology and extent of idiopathic urethral stricture in an Australian population.

Lichen sclerosus (LS) is considered a causative factor in 10% of cases of idiopathic urethral stricture disease (IUSD), which is important for determining management strategies due to the underlying pathophysiology. Traditional excision urethroplasty may not be effective as inflammation often extends beyond the macroscopic stricture. This pilot study aims to answer two research questions: is LS an underlying cause of some idiopathic cause of strictures, and, if there is histological evidence suggesting predisposition of the surrounding tissue to strictures. Biopsies were taken from the stricture site as well as 1 and 2 cm proximal and distal in patients with IUSD. Histological features, including macroscopic and microscopic findings, were reported, including the presence of LS, hyperkeratosis, epidermal changes, lichenoid infiltrates, ulceration, scarring, and inflammation. Methylene blue was used to aid in locating damaged urothelium. Patients were prospectively followed up after urethroplasty. From 109 urethroplasties performed between 2019 to 2022, 15 male patients were enrolled after meeting specific inclusion criteria. These criteria included a diagnosis of IUSD and the absence of any evidence of trauma, macroscopic inflammatory disease, or previous endoscopic instrumentation of the urethra. Patients had to be at least 16 years old and medically suitable for undergoing urethroplasty. The study was approved by the hospitals ethics committees. None had macroscopic evidence of LS. One patient had microscopic evidence of LS at the 2 cm proximal biopsy only. A total of 93% of patients had scarring proximal and distal to the stricture, while 20-40% had inflammatory change. The patient with microscopic LS and two inflammatory change patients had stricture recurrence after urethroplasty. Additionally, one patient with inflammatory changes was diagnosed with penile intraepithelial neoplasia (PeIN) and underwent partial penectomy. Findings suggest that an underlying cause of IUSD could be LS. Additionally, the pathophysiology may involve scarring and inflammation beyond the limits of the stricture with extension distal from the stricture site. Careful evaluation for concomitant urethral pathology should be considered in cases of inflammatory changes. These findings should be considered in the surgical management of IUSD and warrant further research into the role of routine biopsy and drug targets in USD.

Correlation between oligohydramnios and anaemia in the third trimester of pregnancy: A study in a tertiary care hospital in Pakistan.

Maintaining normal amniotic fluid index and normal hemoglobin level is crucial for normal fetal development. Their reduction can lead to maternal and fetal morbidity in the form of operative delivery and poor perinatal outcome such as, low birth weight. There is an association between oligohydramnios and anaemia, although there is scarcity on this correlation in literature. Early detection of oligohydramnios can improve maternal and perinatal outcome. This study aimed to investigate the association between oligohydramnios and anaemia during the third trimester of pregnancy. This retrospective cohort study was conducted at NESCOM Hospital, Pakistan. The study spanned from August 1, 2021, to July 31, 2022. The study included 109 pregnant individuals with oligohydramnios, resulting in an incidence of 22% among the total of 551 deliveries during the study period. The average age of participants was 29.75 years. The average gestational age was 33.52 weeks, with a range of 28 to 38 weeks. The analysis indicated that 44.03% of cases with oligohydramnios were associated with anaemia, followed by idiopathic causes (41.28%). Pearson's correlation revealed a significant association between oligohydramnios and anaemia (r = 0.307, p = 0.001), supporting the hypothesis of a potential interconnection between these two conditions. Regarding delivery outcomes, 81.6% underwent cesarean section, emphasizing the need for careful management in cases of oligohydramnios and anaemia. Neonatal outcomes indicated that 1.8% and 44.5% of neonates were extremely low birth weight and low birth weight, respectively. This study provides empirical evidence supporting a significant association between oligohydramnios and anaemia in the third trimester.

Associations between olfactory dysfunction and cognition: a scoping review.

Strong evidence suggests that olfactory dysfunction (OD) can predict additional neurocognitive decline in neurodegenerative conditions such as Alzheimer's and Parkinson's diseases. However, research exploring olfaction and cognition in younger populations is limited. The aim of this review is to evaluate cognitive changes among non-elderly adults with non-COVID-19-related OD. We performed a structured comprehensive literature search of PubMed, Ovid Embase, Web of Science, and Cochrane Library in developing this scoping review. The primary outcome of interest was the association between OD and cognitive functioning in adults less than 60years of age. We identified 2878 studies for title and abstract review, with 167 undergoing full text review, and 54 selected for data extraction. Of these, 34 studies reported on populations of individuals restricted to the ages of 18-60, whereas the remaining 20 studies included a more heterogeneous population with the majority of individuals in this target age range in addition to some above the age of 60. The etiologies for smell loss among the included studies were neuropsychiatric disorders (37%), idiopathic cause (25%), type 2 diabetes (7%), trauma (5%), infection (4%), intellectual disability (4%), and other (18%). Some studies reported numerous associations and at times mixed, resulting in a total number of associations greater than the included number of 54 studies. Overall, 21/54 studies demonstrated a positive association between olfaction and cognition, 7/54 demonstrated no association, 25/54 reported mixed results, and only 1/54 demonstrated a negative association. Most studies demonstrate a positive correlation between OD and cognition, but the data are mixed with associations less robust in this young adult population compared to elderly adults. Despite the heterogeneity in study populations and outcomes, this scoping review serves as a starting point for further investigation on this topic. Notably, as many studies in this review involved disorders that may have confounding effects on both olfaction and cognition, future research should control for these confounders and incorporate non-elderly individuals with non-psychiatric causes of smell loss.

Frequency and characteristics of chronic fatigue syndrome in multiple sclerosis patients at a university hospital in Eastern Saudi Arabia.

Multiple sclerosis (MS) is a chronic, inflammatory demyelinating disease that affects various parts of the central nervous system. Fatigue, a common symptom, transient, prolonged, or chronic experienced by individuals with MS, can significantly impact daily functioning. It can be associated with underlying pathological processes or can have an idiopathic cause, such as chronic fatigue syndrome (CFS). The study aimed to assess the presence and etiology of fatigue in MS patients and its relationship with CFS. This cross-sectional study was conducted in the Eastern Province of Saudi Arabia. Data were collected using a questionnaire from a sample of 225 MS patients receiving care at our university hospital. The questionnaire included the Centers for Disease Control and Prevention (CDC) criteria for diagnosing CFS and the Expanded Disability Status Scale to evaluate fatigue in MS patients. Of the total of 225 MS patients who participated in this study, 87.1% were diagnosed with relapsing-remitting MS, 6.7% with primary progressive MS, 3.6% with clinically isolated syndrome, and 2.7% with secondary progressive MS. About 53% had experienced fatigue that persisted for over 6 months. Analysis of CFS diagnosis revealed that 7.3% of patients met both CDC criteria and self-reported answers while 17.5% reported having CFS despite not meeting the CDC criteria. These findings highlight a significant lack of agreement between patient-reported diagnoses and established criteria, indicating poor agreement (P = 0.028). The study found an association between CFS and MS, and a significant impact on daily functioning. The study revealed lack of agreement between patient-reported diagnoses and established criteria for CFS. This emphasizes the need for a standardized approach to diagnosis and evaluation of fatigue in MS patients.
