Disabling Pansclerotic Morphea: A century of discovery.

Disabling pansclerotic morphea (DPM) is a rare systemic inflammatory disorder at the severe end of the localized scleroderma spectrum which primarily affects children under 14 years of age. The disease is characterized by rapid sclerosis with circumferential involvement that frequently extends to the fascia, muscle, and bone. Disease progression often involves development of sclerotic plaques, chronic skin ulcers, and painful joint contractures leading to patient immobility with a high mortality rate. Internal organ fibrosis is typically absent. The aggressive and systemic nature of the disease leads patients to seek multidisciplinary care where current therapies are targeted towards immunomodulation and measures to preserve mobility while limiting infection, but often have limited efficacy. Here, we summarize all DPM patients in the English literature, common clinical symptoms, laboratory investigations, and treatments reported to date. Assessment of published cases suggest that the number of therapies does not influence disease outcome and that female patients were younger at the time of reported death. Clinician familiarity and awareness of common DPM symptoms are important for an accurate and early diagnosis. Furthermore, knowledge of the treatments that have been reported to be effective in mitigating disease progression may be helpful in expanding the treatment options available to patients.

Clinical and epidemiological characteristics of patients with pheochromocytoma and retroperitoneal paraganglioma

Introduction. Pheochromocytoma/paraganglioma (PPGL) is a rare hormonally active tumor of chromaffin tissue. Delayed diagnosis of this disease can lead to severe, even fatal, complications. Surgical treatment of PPGL without the necessary preoperative preparation can cause intraoperative uncontrolled hemodynamic impairment. In addition, since 2017, PPGL has been recognized as a malignant tumor due to the presence of metastatic potential. All these factors determine the need for early diagnosis of PPGL, which is based, first of all, on knowledge of the clinical picture by specialists in various fields.Aim. To check and confirm the epidemiological characteristics of PPGL as well as the most common clinical symptoms in the whole group of PPGL and in subgroups of clinical forms; to form a risk group for screening for PPGL.Materials and methods. There were enrolled 353 patients in the study. These patients were operated on at the St. Petersburg State University Hospital in the period from 2010 to 2022 inclusive. All the patients were verified PPGL diagnosis histologically. Clinical symptoms were assessed: a) retrospectively, by analyzing complaints and anamnesis from the initial examination in medical histories upon admission to the hospital for surgical treatment b) both in the entire group as a whole and in subgroups of clinical forms (paroxysmal, constant, mixed, asymptomatic). Statistical analysis was performed using the Python 3.11 programming language (Python Software Foundation, USA). descriptive statistics of quantitative characteristics are presented in the form of medians, first and third quartiles in me format [q1; q3], categorical features – in the form of absolute and relative frequencies in the format n (%). the frequency histogram was constructed using the Matplotlib 3.8.2 library.Results. PPGL is most common in women over 40 years of age. The most common symptoms of PPGL are the following: a feeling of rapid heartbeat (55.95%), headache (41.07%), arterial hypertension (AH) in the form of hypertensive crises (55.65%), constant increase in blood pressure (38.39%), episodes of moderate increases in blood pressure (24.11%), sweating (30.65%), general weakness and fatigue (26.19%), hot flashes or chills (24.11%). These symptoms are formed into the criteria for screening for PPGL. In the asymptomatic clinical form – lower back pain is more common (14%); with paroxysmal – panic attacks (10%); with mixed – thirst and dry mouth (10%), and with constant form – the actual constant nature of hypertension (100%).Conclusion. In a large sample of patients with a rare pathology, the most characteristic symptom complex was identified, characteristic of both PPGL and individual clinical forms. A risk group has been formed for screening for PPGL.

Relationships between clinical symptoms, cognitive functioning, and TMS-evoked potential features in patients with major depressive disorder.

Cognitive impairment is a common clinical symptom of patients with major depressive disorder (MDD). Transcranial magnetic stimulation-evoked potentials (TEPs) detect cortical excitability and connectivity and provide potential biomarkers for MDD patients and their cognitive impairment. This study aimed to investigate the interrelationships between clinical symptoms, cognitive function, and electrophysiological marker TEPs in patients with MDD. A total of 117 participants were recruited, including 59 MDD patients and 58 healthy controls. Clinical symptoms were assessed by the Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale, and cognitive functioning was assessed by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). TEPs were recorded by transcranial magnetic stimulation combined with electroencephalography (TMS-EEG). MDD patients exhibited lower RBANS total (P < 0.001), immediate memory (P = 0.001), language (P = 0.003), attention (P < 0.001), and delayed memory (P = 0.008) scores than HCs. Patients with MDD had larger amplitudes for N100 (P = 0.040) and N280 (P = 0.037), compared to HCs. Correlation analysis indicated significant correlations between the following RBANS scores and TEPs: language and N45 amplitude (r = 0.222, P = 0.024), language and P60 amplitude (r = 0.278, P = 0.004), attention and P180 amplitude (r = 0.213, P = 0.030), RBANS total score and P30 amplitude (r = 0.198, P = 0.044), visuospatial/constructional index and N100 amplitude (r = -0.272, P = 0.005). The results of this study indicate that cortical dysfunction and cognitive impairment are present in patients with MDD and that there is a strong correlation between them, suggesting that TEPs detected by the TMS-EEG may be used as a biomarker for MDD patients and their cognitive impairment.

Wilson’s disease: A Comprehensive Review of Genetics, Pathophysiology, Clinical Symptoms, Diagnostic Techniques and Current Treatment

Introduction: Wilson's disease (WD) is a genetic disease, inherited in an autosomal recessive manner, caused by a mutation in the ATP7B gene, which results in impaired excretion of copper in the bile. This causes the accumulation of copper in various tissues and organs, leading to their damage. The range and severity of symptoms are wide, so diagnosis is difficult and requires a high index of suspicion. The most common clinical symptoms are hepatic and neuropsychiatric symptoms. Diagnosis is based primarily on clinical suspicion, typical symptoms and reduced serum ceruloplasmin concentration. Treatment includes pharmacological therapies, and in some cases liver transplantation is necessary. Wilson's disease, if left untreated, inevitably leads to serious disability and death. Purpose of the work: This study aims to review and characterize the clinical and pathophysiological aspects of Wilson’s disease. Materials and methods: A comprehensive analysis of research papers available on PubMed, Google Scholar, Web of Science, Embase and Scopus was undertaken using the searchterms encompassing the following keywords: Wilson’s disease, Copper metabolism, Copper toxicity, ATP7B, Ceruloplasmin, Gene Mutation Results: Wilson's disease is a rare genetic disorder that can lead to severe disability and even death. For this reason, rapid diagnosis and appropriately selected and individualized treatment play a key role. Wilson's disease remains a major diagnostic challenge, but new techniques for its diagnosis, such as genotype analysis, mainly through sequencing, as well as newborn screening, may significantly improve patient prognosis in the future.

Acute Quetiapine Intoxication: Relationship Between Ingested Dose, Serum Concentration and Clinical Presentation-Structured Literature Review and Analysis.

Over the past decade, quetiapine has become one of the most commonly used psychotropic drugs in acute intoxication events worldwide. A structured literature review and analysis were conducted to assess the relationship between the kinetic and dynamic profiles in acute quetiapine intoxication. The correlation between dose and peak serum concentration (cmax) was determined using Pearson's correlation coefficient. Binary logistic regression was used to evaluate dose and cmax as predictors of the most common clinical events, signs and symptoms. One hundred and thirty-four cases of acute quetiapine ingestion were included in the analysis, with a median ingested dose of 10 g and a median cmax of 4 mg/L. The typical half-life was estimated to be 16.5 h, significantly longer than at therapeutic doses. For the immediate-release formulation, a biphasic disposition could not be excluded. Dose and cmax demonstrated a weak but significant correlation (r = 0.256; N = 63; p = 0.043). Central nervous system depression and tachycardia were the most common clinical signs. Higher doses and concentrations increased the risk of severe intoxication and were good predictors of intubation, tachycardia, hypotension, QTc prolongation and seizures, but not QRS prolongation, arrhythmia, heart block, hypokalaemia or acidosis. The thresholds for dose and cmax that increased the risk for individual signs and symptoms varied widely. However, doses > 3 g or cmax > 2 mg/L can be considered as alert levels that represent a high risk for severe clinical course of acute quetiapine intoxication.

Crimean-Congo hemorrhagic fever cases diagnosed during an outbreak of Sudan virus disease in Uganda, 2022-23.

In September 2022, Uganda experienced an outbreak of Sudan virus disease (SVD), mainly in central Uganda. As a result of enhanced surveillance activities for Ebola disease, samples from several patients with suspected viral hemorrhagic fever (VHF) were sent to the VHF Program at Uganda Virus Research Institute (UVRI), Entebbe, Uganda, and identified with infections caused by other viral etiologies. Herein, we report the epidemiologic and laboratory findings of Crimean-Congo hemorrhagic fever (CCHF) cases that were detected during the SVD outbreak response. Whole blood samples from VHF suspected cases were tested for Sudan virus (SUDV) by real-time reverse transcription-polymerase chain reaction (RT-PCR); and if negative, were tested for CCHF virus (CCHFV) by RT-PCR. CCHFV genomic sequences generated by metagenomic next generation sequencing were analyzed to ascertain strain relationships. Between September 2022 and January 2023, a total of 2,626 samples were submitted for VHF testing at UVRI. Overall, 13 CCHF cases (including 7 deaths; case fatality rate of 53.8%), aged 4 to 60 years, were identified from 10 districts, including several districts affected by the SVD outbreak. Four cases were identified within the Ebola Treatment Unit (ETU) at Mubende Hospital. Most CCHF cases were males engaged in livestock farming or had exposure to wildlife (n = 8; 61.5%). Among confirmed cases, the most common clinical symptoms were hemorrhage (n = 12; 92.3%), fever (n = 11; 84.6%), anorexia (n = 10; 76.9%), fatigue (n = 9; 69.2%), abdominal pain (n = 9; 69.2%) and vomiting (n = 9; 69.2%). Sequencing analysis showed that the majority of identified CCHFV strains belonged to the Africa II clade previously identified in Uganda. Two samples, however, were identified with greater similarity to a CCHFV strain that was last reported in Uganda in 1958, suggesting possible reemergence. Identifying CCHFV from individuals initially suspected to be infected with SUDV emphasizes the need for comprehensive VHF testing during filovirus outbreak responses in VHF endemic countries. Without expanded testing, CCHFV-infected patients would have posed a risk to health care workers and others while receiving treatment after a negative filovirus diagnosis, thereby complicating response dynamics. Additionally, CCHFV-infected cases could acquire an Ebola infection while in the ETU, and upon release because of a negative Ebola virus result, have the potential to spread these infections in the community.

Clinicopathological, immunohistochemical and therapeutic approaches on survival in patients with epithelioid glioblastoma: Institutional experience in the management of 58 patients

Epithelioid glioblastoma (Ep-GBM) is a rare variant of glioblastoma characterized by a high recurrence rate and poor prognosis. Currently, there is no established standard treatment for Ep-GBM. Therefore, we identified 58 Ep-GBM cases to investigate these characteristics and identify the possible prognostic factors of survival. There were 30 male and 28 female patients with a median age of 39 years. Headaches and dizziness were the most common clinical symptom. The tumor is most frequently located in the temporal lobe (36.2%). The positivity rate for BRAF-V600E is 56.9% (33/58), for MGMT is 56.9% (33/58), and for INI-1 is 75% (30/40). Tumor recurrence was observed in 39 patients. The median progression-free survival (PFS) of all patients was 12.7 months, while the median overall survival (OS) was 29.1 months. Additionally, the median survival time after recurrence was 14.3 months. Both univariate and multivariate COX regression analyses revealed that individuals who received more than six cycles of adjuvant oral temozolomide experienced a longer median PFS compared to those who received fewer cycles. Characteristics associated with poorer PFS included tumor dissemination prior to initial surgery. Additionally, both analyses identified tumor dissemination, radiotherapy and adjuvant oral temozolomide as predictors of OS. Notably, for patients with recurrent Ep-GBM, reoperation was shown to significantly increase survival time after recurrence. In conclusion, the standard Stupp regimen is also applicable to patients with Ep-GBM, extending adjuvant oral temozolomide could further improve survival for Ep-GBM patients, reoperation may also prolong survival for recurrent Ep-GBM.

The role and mechanism of CRISPLD2 in skin fibrosis of systemic sclerosis.

Systemic sclerosis (SSc) is an autoimmune connective tissue disease involving multiple organs. The most common clinical symptom of SSc is progressive fibrosis of the skin, and the pathologically manifestations of skin were activation and proliferation of fibroblasts and continuous proliferation of extracellular matrix. Transforming growth factor β (TGFβ) can promote the proliferation and activation of fibroblasts, causing excessive deposition of collagen and structural proteins. Therefore, exploring the specific mechanism of TGFβ-related pathway on fibrosis is of great significance for improving skin fibrosis in SSc. Genes related to TGFβ pathway were screened through bioinformatics analysis, and SSc phenotypes were verified in vivo and vitro. The relevant molecular mechanisms were preliminarily discussed in combination with transcriptome sequencing. Human cysteine-rich secreted protein LCCL domain protein 2 (CRISPLD2) was found increased reactivity in TGFβ induced fibroblasts, and the expression of ACTA2 (ɑ-SMA) decreased significantly in TGFβ-mediated fibroblasts with up-regulation of CRISPLD2. CRISPLD2 was found increased reactivity in TGFβ induced fibroblasts, and we further confirmed that CRISPLD2 can participate in TGFβ induced fibroblast fibrosis from multiple perspectives and levels in negative feedback regulation, and investigated the mechanism of CRISPLD2 in fibrosis.

Clinical assessment of ectopic pregnancy in a tertiary care hospital: An observational study

Background: Ectopic pregnancy is defined as pregnancy that occurs outside normal uterine cavity that occurs due to implantation of fertilized ovum in an aberrant site which is conducive to its growth and development. In developing countries like India, late presentations with tubal rupture and hemodynamic instability, late presentations with tubal rupture causes first trimester maternal morbidity and mortality. For early diagnosis, a clinician should be well aware about the various presentations of ectopic pregnancy. Aims and Objectives: (a) To estimate the incidence, risk factors, clinical manifestations and outcome following different management protocol. (b) To estimate the morbidity and mortality with respect to different types of presentation and management. (c) To understand the need for clinical assessment in order to diagnose early and provide urgent intervention and also to lean toward the possibility of conservative approach in order to preserve fertility. Materials and Methods: The current study was a time bound, Observational descriptive study with Longitudinal design. It was conducted in the Department of Obstetrics and Gynecology, R. G. Kar Medical College and Hospital, between March 2021 and August 2022. One hundred and thirty-eight participants, suspected to have ectopic pregnancy were enrolled for the study. Data collection was done by detailed history taking and physical examination. The basic investigations including hemoglobin, ABO and Rhesus typing, urine pregnancy test, and ultrasound (USG) examination were done. All data were collected on a structural data form and analyzed for descriptive statistics. Post-operative histopathological examination (HPE) reports were collected and final diagnosis was made. Results: About 63.8% of the study population belonged to 21–30 years of age. About 63.7% patients presented with &gt;5–8 weeks of amenorrhea. About 18.1% of the study population were sterilized and the duration between the sterilization and the occurrence of ectopic was 4–10 years in 64% patients. The most common risk factor was h/o Previous C-section (31.8%). The most common clinical symptom was abdominal pain present in 131 (94.9%), 44 (31.9%) participants had all the three classical symptoms with 100% specificity. On examination, forniceal fullness/tenderness was the most specific finding. The most common USG finding was Adnexal mass with empty Uterine cavity with Free fluid (49.2%). Most of the patients were managed with Partial Salpingectomy (30.4%). The final diagnosis of ectopic was made in 129 patients, which was confirmed by HPE reports in 124 patients. Five patients underwent medical treatment. Conclusion: Early diagnosis before rupture and referral are the key factor in reducing the maternal morbidity and mortality.

CARD8 polymorphisms among bacterial meningitis patients in North-West Ethiopia

BackgroundThe severity of infectious disease outcomes is dependent on the virulence factors of the pathogen and the host immune response. CARD8 is a major regulator of the innate immune proinflammatory response and has been suggested to modulate the host response to common inflammatory diseases. In the present study, the C10X genetic polymorphism in the CARD8 gene was investigated in relation to bacterial meningitis.MethodsA total of 400 clinically suspected meningitis patients hospitalized at the University of Gondar Hospital were enrolled in the study. Cerebrospinal fluid (CSF) and blood samples were collected for laboratory investigations. The collected CSF was cultured, and all the results obtained from the culture were confirmed using direct RT‒PCR. Genotyping of whole-blood samples was performed using a TaqMan assay. The results were compared with apparently healthy controls and with PCR-negative meningitis suspected patients.ResultsOf the included patients, 57% were men and the most common clinical signs and symptoms were fever (81%), headache (80%), neck stiffness (76%), nausea (68%), and vomiting (67%). Microbiology culture identified 7 patients with bacterial meningitis caused by Neisseria meningitidis (n = 4) and Streptococcus pneumoniae (n = 3). The RT-PCR revealed 39 positive samples for N. meningitidis (n = 10) and S. pneumoniae (n = 29). A total of 332 whole-blood samples were genotyped with the following results: 151 (45.5%) C10X heterozygotes, 59 (17.7%) C10X homozygotes and 122 (36.7%) wild genotypes. The polymorphic gene carriers among laboratory confirmed, clinically diagnosed meningitis and healthy controls were 23(46%), 246(40%), and 1526(39%), respectively with OR = 1.27 (0.7–2.3) and OR = 1.34 (0.76–2.4). The presence of the C10X polymorphism in the CARD8 gene was more prevalent in suspected meningitis patients than in healthy controls (OR 1.2; 1.00-1.5). Homozygote C10X polymorphic gene carriers were more susceptible to infectious disease. The presence of viable or active bacterial infection was found to be associated with the presence of heterozygous C10X carriers.ConclusionsA greater proportion of C10X in the CARD8 gene in confirmed bacterial meningitis patients and clinically diagnosed meningitis patients than in healthy controls. Homozygote C10X polymorphic gene carriers were more susceptible to infectious disease than heterozygote gene carriers and healthy controls.

Risk factors for diarrheal diseases among pilgrims during Arba’een mass gathering: a case-control study

BackgroundA significant portion of the Muslim community participates in the Arba’een pilgrimage, with participant numbers increasing each year. There have been relatively few studies on the health of Arba’een Mass gathering (MG). Researching the prevalence and distribution of diseases among Arba’een pilgrims is essential to recognize any outbreaks and take timely responses to contain them. The current study aimed to identify exposures and risk factors for diarrheal disease in pilgrims who referred to the clinics located in Iraq among the Arba’een MG in 2023.MethodsThis case-control study randomly selected 200 outpatients (100 cases and 100 controls) who were referred to Iraq clinics. Cases were patients with gastrointestinal symptoms (diarrhea), while controls were randomly selected from unaffected pilgrims at the same time for the cases. The study groups matched for age, and sex. Face-to-face interviews using a reliable field based checklist of the Center for Disease Control and Prevention of Iran’s Ministry of Health to collect potential exposures and risk factors for diarrheal disease. Multiple logistic regression was used to estimate the crude and adjusted odds ratio (AOR) for the risk of diarrhea with a 95% confidence interval (CI).ResultsThe average age of the participants was 38.6 years. Diarrhea in 100% and fever in 81% were the most common clinical symptoms in patients. Having underlying diseases was not associated with an increased risk of diarrhea disease (P > 0.05). Regarding risk factors for diarrheal, the final analysis after adjusting for potential confounders indicated that consumption of insanitary (unpackaged) drinking water (AOR = 1.95; 95% CI: 1.05–3.6; P = 0.024), inappropriate hand washing (AOR = 3.82; 95% CI: 1.7–8.6; P = 0.001), ritual foods (AOR = 2.56; 95% CI: 1.3–5.2; P = 0.004), and public toilets (AOR = 1.46; 95% CI: 1.04–4.3; P = 0.038) were significantly increased the likelihood of diarrheal disease.ConclusionsContamination of water sources, food, inadequate and poor hand washing were the most common sources of diarrheal diseases among Arba’een pilgrims. The results indicate that the potential occurrence of outbreaks, especially water- and foodborne diseases, threatens participants in the Arba’een MG. It is recommended to provide risk assessment, improve pilgrims’ awareness, pre-and post-screening, vaccination, compliance with personal hygiene, improvement of the environment, provision of sanitary water and food sources and hygienic disposal of sewage, laboratory diagnosis to identify the common types of pathogens in Arba’een MG.

Dengue hemorrhagic fever is rising in many localities nationwide, including Nghe An. The movement of people carrying the Dengue virus increases the risk of an outbreak. The study aimed to describe dengue's epidemiological, clinical and paraclinical characteristics in children. The results show that children living in rural areas have a higher infection rate than those in urban areas; the disease frequency is mainly in the rainy season from August to December. There are 50% of children hospitalized in the early stages of the disease. The danger of the disease is that common clinical symptoms are joint pain and muscle fatigue; tired, abdominal pain in the liver area, and enlarged liver; Hemorrhagic manifestations, of which subcutaneous bleeding is the most common; 4.7% had symptoms of shock due to dengue fever; 31.3% had a platelet count reduced below 50.109/l. Subclinical liver enzymes (GOT, GPT) increased mainly at mild and moderate levels. Dengue IgM and Dengue NS1Ag tests appeared in 3 stages of the disease; Dengue IgG only appeared in the later stages, in which the recovery phase accounts for the highest rate. Dengue hemorrhagic fever can have clinical manifestations ranging from mild to severe, with complications of hypovolemic shock that can potentially lead to cardiovascular collapse, severe organ failure shock or severe bleeding. If not detected and treated promptly, it can lead to death, especially in children. Keywords: Dengue hemorrhagic fever; children; Nghe An Obstetrics and Pediatrics Hospital.

Divergent pattern of functional connectivity within the dorsal attention network differentiates schizophrenia and bipolar disorder patients.

Schizophrenia (SZ) and bipolar disorder (BD) share common clinical features, symptoms, and neurocognitive deficits, which results in common misdiagnosis. Recently, it has been suggested that alterations within brain networks associated with perceptual organization yield potential to distinguish SZ and BD individuals. The aim of our study was to evaluate whether functional connectivity (FC) of the dorsal attention network (DAN) may differentiate both conditions. The study involved 90 participants: 30 remitted SZ patients, 30 euthymic BD patients, and 30 healthy controls (HC). Resting state functional magnetic resonance imaging was used to compare the groups in terms of the FC within the core nodes of the DAN involving frontal eye fields (FEF) and intraparietal sulcus (IPS). BD patients presented weaker inter-hemispheric FC between right and left FEF than HC. While SZ did not differ from HC in terms of inter-FEF connectivity, they presented increased inter- and intra-hemispheric FC between FEF and IPS. When compared with BD, SZ patients showed increased FC between right FEF and other nodes of the network (bilateral IPS and left FEF). We have shown that altered resting state FC within DAN differentiates BD, SZ, and HC groups. Divergent pattern of FC within DAN, consisting of hypoconnectivity in BD and hyperconnectivity in SZ, might yield a candidate biomarker for differential diagnosis between both conditions. More highly powered studies are needed to confirm these possibilities.

The healing effect of nano emulsified Plantago major L extract on oral wounds in a wistar rat model

IntroductionOral lesions are a common clinical symptom arising from various etiologies and disrupt the patient’s quality of life. However, no definite treatment is not yet possible, due to the constantly changing environment of the mouth. In recent years, herbal treatments have gained popularity among patients and physicians due to their availability, safety, affordability, and antimicrobial properties. This research aims to investigate the therapeutic effects of a nano-emulsion of Plantago major standardized extract (PMSE) on oral ulcers in a Wistar rat model using histomorphometry and stereological parameters.Materials and MethodsThe study involved 72 Wistar rats divided randomly into 24 groups of 3 each: groups A1 to A4 received one dose to 4 doses of 5% PMSE nano emulsion, groups B1 to B4 received one dose to 4 doses of 10% PMSE nano emulsion, and groups C1 to C4 received one dose to 4 doses of 20% PMSE nano emulsion, groups D1 to D4 received one dose to 4 doses of nano-emulsion without PMSE, groups E1 to E4 received one dose to 4 doses of PMSE, and group F served as the control group. An incision measuring 2 mm in diameter was made in the animals’ hard palate using a biopsy punch. A swab containing the necessary material was used to administer the medication orally to the wound. Histological samples were collected on days 2, 4, 6, and 8 and sent to the pathology laboratory for examination. Data analysis was performed using SPSS 26 and setting statistical significance at p < 0.05.ResultsGroup A showed a high rate of complete and normal re-epithelialization of the wound at 66.7%, compared to the other groups. Group D had a re-epithelialization rate of 50%, while groups C, E, and F had rates of 7.41% and group B had 7.16%. In terms of inflammation reduction, 23.88% of group A had no inflammation, a higher percentage compared to the other groups. Group B and D had no inflammation in 3.33% of cases, lower than the other groups. The study evaluated frequency of re-epithelialization and inflammation levels in different groups on days 2, 4, 6, and 8 after four doses of the drug with no significant differences found among the groups.ConclusionNone of the nano emulsions or PMSE enhanced the healing rate of oral ulcers. However, a 5% PMSE nano emulsion displayed an increase in lesion re-epithelialization.

Clinical characteristics and outcomes of patients with antibody-related autoimmune encephalitis presenting with disorders of consciousness: A prospective cohort study.

To explore the clinical characteristics, short- and long-term functional outcomes, and risk factors for antibody-related autoimmune encephalitis (AE) in patients with disorders of consciousness (DoC). Clinical data were collected from AE patients admitted to Xuanwu Hospital of Capital Medical University from January 2012 to December 2021, and patients were followed up for up to 24 months after immunotherapy. A total of 312 patients with AE were included: 197 (63.1%) with anti-NMDAR encephalitis, 71 (22.8%) with anti-LGI1 encephalitis, 20 (6.4%) with anti-GABAbR encephalitis, 10 (3.2%) with anti-CASPR2 encephalitis, 10 (3.2%) with anti-GAD65 encephalitis, and 4 (1.3%) with anti-AMPAR2 encephalitis. Among these patients, 32.4% (101/312) presented with DoC, and the median (interquartile range, IQR) time to DoC was 16 (7.5, 32) days. DoC patients had higher rates of various clinical features of AE (p < .05). DoC was associated with elevated lumbar puncture cerebrospinal fluid (CSF) pressure, CSF leukocyte count, and specific antibody titer (p < .05). A high percentage of patients in the DoC group had a poor prognosis at discharge and at 6 months after immunotherapy (p < .001), but no significant difference in prognosis was noted between the DoC group and the non-DoC group at 12 and 24 months after immunotherapy. Dyskinesia (OR = 3.266, 95% CI: 1.550-6.925, p = .002), autonomic dysfunction (OR = 5.871, 95% CI: 2.574-14.096, and p < .001), increased CSF pressure (OR = 1.007, 95% CI: 1.001-1.014, p = .046), and modified Rankin scale (mRS) score ≥3 at the initiation of immunotherapy (OR = 7.457, 95% CI: 3.225-18.839, p < .001) were independent risk factors for DoC in AE patients. DoC is a relatively common clinical symptom in patients with AE, especially critically ill patients. Despite requiring longer hospitalization, DoC mostly improves with treatment of the primary disease and has a good long-term prognosis after aggressive life support and combination immunotherapy.

Characteristics and prognosis of LGI1 antibody encephalitis

Objectives: To investigate clinical manifestations and outcomes of patients with LGI1 autoimmune encephalitis. Methods: A total of 12 patients who were diagnosed with LGI1 autoimmune encephalitis were retrospectively analyzed between 2018 and 2022 at the Department of Neurology of the Affiliated Hospital of Xuzhou Medical University. Clinical characteristics, laboratory examinations, electroencephalograms, brain magnetic resonance images and prognosis were assessed. The clinical data were collected by searching through electronic medical records. Results: Among 12 patients, 8 were male and 4 were female. The average age at disease onset was 61.8 years (24–83). The most common clinical symptoms were seizures (n=10), cognitive dysfunction (n=8), and mental behavioral disorders (n=8). A total of 9 cases had hyponatremia. Brain MRI and electroencephalographic were abnormal in 7 patients each. All patients were treated with first line immunotherapy. Most patients responded well and 3 patients relapsed on follow-up. Conclusion: Characteristic features of LGI1 antibody encephalitis include subacute onset cognitive impairment, seizures, faciobrachial dystonic seizures (FBDS), and mental and behavioral abnormalities. Especially, FBDS and hyponatremia suggest LGI1-antibody encephalitis. Therefore, early identification and immunotherapy may prevent cognitive impairment and improve prognosis.

Clinical characteristics, longitudinal adaptive functioning, and association with electroencephalogram activity in PPP2R5D-related neurodevelopmental disorder.

Protein phosphatase 2 regulatory subunit B56δ related neurodevelopmental disorder (PPP2R5D-related NDD) is largely caused by de novo heterozygous missense PPP2R5D variants. We report medical characteristics, longitudinal adaptive functioning, and in-person neurological, motor, cognitive, and electroencephalogram (EEG) activity for PPP2R5D-related NDD. Forty-two individuals (median age 6 years, range = 0.8-25.3) with pathogenic/likely pathogenic PPP2R5D variants were assessed, and almost all variants were missense (97.6%) and de novo (85.7%). Common clinical symptoms were developmental delay, hypotonia, macrocephaly, seizures, autism, behavioral challenges, and sleep problems. The mean Gross motor functional measure-66 was 60.2 ± 17.3% and the mean Revised upper limb module score was 25.9 ± 8.8. The Vineland-3 adaptive behavior composite score (VABS-3 ABC) at baseline was low (M = 61.7 ± 16.8). VABS-3 growth scale value scores increased from baseline in all subdomains (range = 0.6-5.9) after a mean follow-up of 1.3 ± 0.3 years. EEG beta and gamma power were negatively correlated with VABS-3 score; p < 0.05. Individuals had a mean Quality-of-life inventory-disability score of 74.7 ± 11.4. Twenty caregivers (80%) had a risk of burnout based on the Caregiver burden inventory. Overall, the most common clinical manifestations of PPP2R5D-related NDD were impaired cognitive, adaptive function, and motor skills; and EEG activity was associated with adaptive functioning. This clinical characterization describes the natural history in preparation for clinical trials.

Clinical and pathologic characterization of African swine fever virus infection in pigs in the Mekong Delta, Vietnam

African swine fever (ASF) is a highly infectious disease in pigs caused by the African swine fever virus (ASFV), which might result in 100% mortality. Pigs infected with ASFV might display different clinical and pathological features depending on virulence and host factors. This study aimed to determine features of clinical symptoms, macroscopic, and microscopic lesions of ASF in the Mekong Delta (MD), Vietnam during 2021–2022. The investigation was conducted following three fatal outbreaks of ASF in Hau Giang, Vinh Long, and Can Tho provinces, which are three central provinces out of thirteen in the MD. The spleen, lymph nodes, liver, kidney, and heart were collected from three infected pigs that displayed clinical symptoms of ASFV infection and confirmed the presence of ASFV by conventional PCR. The results indicated that infected pigs showed common clinical symptoms including high fever, anorexia, and moderate petechiae on the skin. Severe hemorrhage was observed in lymph nodes, spleen, kidneys, intestines, and gallbladders which were the main lesions during post-mortem examination. Microscopic lesions were characterized by lymphocytopenia, atrophy of lymphoid follicles in the immune system. However, distinct variations in clinical symptoms, macroscopic, and microscopic features among ASFV infection cases were not documented. This study provides a further understanding of the clinical presentation and pathological lesions caused by the ASFV strain circulating in the MD.

Knowledge, attitude, and perception about Marburg virus in healthcare workers of India

BackgroundThe recent Marburg virus outbreaks in Equatorial Guinea and Tanzania in March 2023 have sparked fears about potential worldwide spread. Thus, assessing healthcare workers’ (HCW) knowledge of the disease is critical, particularly in India, where the healthcare system is underfunded and understaffed and already has an immense burden of infectious illnesses.MethodsWe carried out a cross-sectional web-based survey among 300 healthcare workers including doctors, nurses, and pharmacists. The Google survey form was circulated online via email. To recruit participants, a convenience sample technique was utilized. Descriptive and logistic regression was applied to analyse data.Results50.9% were aware of Marburg virus disease, and 60.5% had a favourable attitude towards Marburg virus disease (MARVD) control and prevention. Bleeding was cited as the most common clinical symptom of MARVD by 53.3% of participants. Regarding the mode of transmission, 51.6% were aware of how MARVD is spread. Almost all HCWs (99%) claimed they would accept an approved vaccine for themselves, however, the readiness to receive experimental treatments was less certain. The logistic regression model showed gender [female—OR: 2.8 (1.75 to 3.5), p = 0.001] and job roles [pharmacist—OR: 4.1 (2.9 to 7.2), P < 0.001] as predictors of poor KAP about MARVD.ConclusionAlthough there was a high degree of awareness about MARVD, there were notable knowledge gaps and differences in attitudes among healthcare professionals. This underlines the importance of customized training programs for each group to increase healthcare workers’ knowledge of MARVD.

The Symptomatic Expression in Chinese Patients with Suspected COVID-19 Omicron Variant Infection: A Clinical Case Registry Study

Little systematic research has been conducted into the symptomatic expression of COVID-19 infections in patients. It is known that symptomatic expression varies between patients, but the nature and extent of this variability is poorly understood. This paper elaborates on the symptoms reported by Chinese patients infected with COVID-19 during the Omicron wave, and compares this with available data from other countries. This was an observational clinical case registry study of Chinese patients with suspected Omicron variant COVID-19 infection. Symptoms were prospectively collected via a 171-item questionnaire and entered into the Clificol COVID-19 Clinical Case Registry. Two types of symptoms were distinguished: A) common clinical symptoms as identified by a search of available/published data, and B) homeopathic symptoms, used for the selection of the most suitable homeopathic medicine. Data were mainly analysed descriptively. Additionally, we compared the prevalence of the reported symptoms with available symptom data from the UK and France. Twenty one Chinese practitioners collected questionnaires on 388 cases that received a first homeopathic prescription between 5 December 2021 and 8 April 2022. With respect to A), the most frequently reported clinical symptoms were respectively cough (71%), fever (65%), extreme tiredness (58%), headache (51%), sore throat (46%), runny nose (34%), unusual muscle pains (31%), hoarseness (21%), eye soreness (8%) and brain fog (6%). With respect to B), homeopathic symptoms related to cough and fever were particularly prevalent. This study identified the reported symptoms of Chinese COVID-19 patients with suspected Omicron variant infection. A more detailed understanding of the clinical presentation of COVID-19 variants in different countries is important for the selection of test-triggering symptoms.
