AIM:To investigate the difference of medial rectus(MR)and lateral rectus(LR)between acute acquired concomitant esotropia(AACE)and the healthy controls(HCs)detected by magnetic resonance imaging(MRI).METHODS:A case-control study.Eighteen subjects with AACE and eighteen HCs were enrolled.MRI scanning data were conducted in target-controlled central gaze with a 3-Tesla magnetic resonance scanner.Extraocular muscles(EOMs)were scanned in contiguous image planes 2-mm thick spanning the EOM origins to the globe equator.To form posterior partial volumes(PPVs),the LR and MR cross-sections in the image planes 8,10,12,and 14 mm posterior to the globe were summed and multiplied by the 2-mm slice thickness.The data were classified according to the right eye,left eye,dominant eye,and non-dominant eye,and the differences in mean cross-sectional area,maximum cross-sectional area,and PPVs of the MR and LR muscle in the AACE group and HCs group were compared under the above classifications respectively.RESULTS:There were no significant differences between the two groups of demographic characteristics.The mean cross-sectional area of the LR muscle was significantly greater in the AACE group than that in the HCs group in the non-dominant eyes(P=0.028).The maximum cross-sectional area of the LR muscle both in the dominant and non-dominant eye of the AACE group was significantly greater than the HCs group(P=0.009,P=0.016).For the dominant eye,the PPVs of the LR muscle were significantly greater in the AACE than that in the HCs group(P=0.013),but not in the MR muscle(P=0.698).CONCLUSION:The size and volume of muscles dominant eyes of AACE subjects change significantly to overcome binocular diplopia.The LR muscle become larger to compensate for the enhanced convergence in the AACE. 展开更多

Background: Hospital Acquired Infections (HAIs) remain a common cause of death, functional disability, emotional suffering and economic burden among hospitalized patients. Knowledge of HAIs is important in its prevention and control. This study seeks to assess the knowledge of Hospital Acquired Infections (HAIs) among medical students in a Tertiary Hospital in Jos North Local Government Area, Plateau State, Nigeria. Methods: This was a descriptive cross-sectional study done in October 2019 among clinical medical students using a Multistage sampling technique. Data was collected using a self-administered structured questionnaire and analyzed using the IBM SPSS 20 (Statistical Package for the Social Sciences). Ethical approval was granted by Bingham University Teaching Hospital, Ethics Committee, Jos, Plateau State. Results: A total of 219 students in the clinical arm of the College of Medicine and Health Sciences were selected. A higher proportion (97.7%) of respondents knew about Hospital Acquired Infections and 85.4% knew that Hospital Acquired infections occur in the hospital, and (86.3%) considered patients contagious with half (58.9%) considered patients as the most important source of HAIs, followed by care givers (13.2%), then doctors including medical students and interns (10.0%) and lastly nurses (8.7%). The majority of respondents (70.8%) considered Surgical Wound Infections to be the most commonly occurring HAI, followed by UTIs (69.9%), RTIs (61.2%), BSIs (37.0%) and others (0.9%). The clinical thermometer was the instrument that most commonly transmits HAIs (82.6%), then followed by stethoscope (62.1%), white coats (53.9%), and blood pressure cuff (51.1%). Most respondents knew the infectious substances, like blood (96.3%), nasal discharge (82.6%), saliva (85.3%), and faeces (79.4%) transmitted HAIs, 72.6% of the respondents said that they were aware of the recommended hand washing techniques by WHO. Conclusion: The majority of students 91.3% had good knowledge while 8.7% had poor knowledge of HAIs. Lower classes had more respondents with poor knowledge. This finding was statistically significant (p = 0.002, Chi-square 12.819). Students are encouraged to keep up the level of knowledge they have about HAIs. These students can help improve the knowledge of those whose knowledge level is low. Government and NGOs should support sponsorship for capacity-building events targeted at HAIs for healthcare workers and medical students. 展开更多

Stroke is a physiological alteration associated with changes in blood flow that can result in sudden-onset cognitive impairment. It has a heterogenous clinical presentation with varying degrees of severity correlated with specific central nervous system zones or areas, and its prognosis is uncertain. This case study describes a 62-year-old male patient with acquired brain damage of the anterior cingulate cortex as a result of an ischemic event in the territory of the left anterior cerebral artery. Cognitive function was assessed using the neuropsychological executive function and frontal lobe test battery (BANFE-2) as well as other neuropsychological tests. The results show a profile of higher mental functions characterized by the presence of dysexecutive syndrome with marked behavioral alteration and diencephalic amnesia. . 展开更多

Alzheimer’s disease(AD) is an age-related neurodegenerative disease characterized by progressive cognitive defects. The role of the central immune system dominated by microglia in the progression of AD has been extensively investigated. However, little is known about the peripheral immune system in AD pathogenesis.Recently, with the discovery of the meningeal lymphatic vessels and glymphatic system, the roles of the acquired immunity in the maintenance of central homeostasis and neurodegenerative diseases have attracted an increasing attention. The T cells not only regulate the function of neurons, astrocytes, microglia, oligodendrocytes and brain microvascular endothelial cells, but also participate in the clearance of β-amyloid(Aβ) plaques. Apart from producing antibodies to bind Aβ peptides, the B cells affect Aβ-related cascades via a variety of antibodyindependent mechanisms. This review systemically summarizes the recent progress in understanding pathophysiological roles of the T cells and B cells in AD. 展开更多

BACKGROUND Acquired haemophilia(AH)is a serious autoimmune haematological disease caused by the production of auto-antibodies against coagulation factor VIII.In some patients,AH is associated with a concomitant malignancy.In case of surgical intervention,AH poses a high risk of life-threatening bleeding.CASE SUMMARY A 60-year-old female patient with multiple recurrences of non-muscle invasive bladder cancer underwent transurethral tumour resection.A severe haematuria developed postoperatively warranting two endoscopic revisions;however,no clear source of bleeding was identified in the bladder.Subsequent haematological examination established a diagnosis of AH.Treatment with factor VIII inhibitor bypass activity and immunosuppressive therapy was initiated immediately.The patient responded well to the therapy and was discharged from the hospital 21 d after the primary surgery.At the 38-mo follow-up,both AH and bladder cancer remained in complete remission.CONCLUSION AH is a rare,life-threatening haematological disease.AH should be considered in patients with persistent severe haematuria or other bleeding symptoms,especially if combined with isolated activated partial thromboplastin time prolongation. 展开更多

The present study aims to contribute to surveillance of the immune and clinical response of vaccines to SARS-CoV-2. Methods: Observational medication study on acquired immunity and effectiveness of vaccines. Population: 620 workers in the health service of Almansa (Spain). Representative sample of 150 individuals. Sociodemographic, clinical, and epidemiological data and samples were recorded to determine anti-SARS-CoV-2 serum IgG levels 6 and 9 months after vaccination with Pfizer. Results: Mean age 46.45 years;76% women;85.1% working in a hospital. 19.3% had had COVID-19 in the year prior to vaccination. 96.7% were fully vaccinated with Pfizer/BioNTech. At 6 months, 100% seropositivity and mean IgG levels of 3017.2 AU/ml. Significant variations in IgG levels in individuals with prior COVID-19 infection and smokers. At 9 months, 99.3% remained seropositive;2.8% infected after vaccination. The repeated measures analysis showed a difference in means of 669.0 AU/ml (significant decrease in IgG levels of 28.9%). Conclusion: Antibody levels remained positive 6 and 9 months after vaccination, although IgG levels were found to decay. 展开更多

We report the first case of a patient with hepatitis C virus(HCV) infection and idiopathic thrombocytopenic purpura(ITP), who later developed acquired amegakaryocytic thrombocytopenia(AAMT), with autoantibodies to the thrombopoietin(TPO) receptor(c-Mpl). A 64-year-old woman, with chronic hepatitis C, developed severe thrombocytopenia and was diagnosed with ITP. She died of liver failure. Autopsy revealed cirrhosis and liver carcinoma. In the bone marrow, a marked reduction in the number of megakaryocytes was observed, while other cell lineages were preserved. Therefore, she was diagnosed with AAMT. Additionally, autoantibodies to c-Mpl were detected in her serum. Autoantibodies to c-Mpl are one of the causes of AAMT, acting through inhibition of TPO function, megakaryocytic maturation, and platelet formation. HCV infection induces several autoantibodies. HCV infection might also induce autoantibodies to c-Mpl, resulting in the development of AAMT. This mechanism may be one of the causes of thrombocytopenia in patients with HCV infection. 展开更多

AIM: To compare the clinical manifestation of cytomegalovirus(CMV) retinitis and microvascular retinopathy(MVR) in patients with acquired immunodeficiency syndrome(AIDS) in China.METHODS: A total of 93 consecutive patients with AIDS, including 41 cases of CMV retinitis and 52 cases of MVR were retrospectively reviewed. Highly active antiretroviral therapy(HAART) status was recorded. HIV and CMV immunoassay were also tested. CD4+ T-lymphocyte count and blood CMV-DNA test were performed in all patients. Aqueous humor CMV-DNA test was completed in 39 patients. Ophthalmological examinations including best corrected visual acuity(BCVA, by International Standard Vision Chart), intraocular pressure(IOP), slit-lamp biomicroscopy, indirect ophthalmoscopy were performed.RESULTS: In MVR group, the anterior segment examination was normal in all patients with a mean BCVA of 0.93±0.13. Blood CMV-DNA was 0(0, 269000) and 42 patients(80.77%) did not receive HAART. In CMV retinitis group, 13 patients(31.71%) had anterior segment abnormality. The mean BCVA was 0.64±0.35 and blood CMV-DNA was 3470(0, 1 450000). Nineteen patients(46.34%) had not received HAART. MVR group and CMV retinitis group the positive rates of aqueous CMV-DNA were 0 and 50%, respectively.Two patients with MVR progressed to CMV retinitis during the follow-up period.CONCLUSION: In comparison of CMV, patients with MVR have relatively mild visual function impairment. Careful ophthalmological examination and close follow-up are mandatory, especially for patients who have systemic complications, positive CMV-DNA test and without received HAART. 展开更多

BACKGROUND Hypoganglionosis is a rare condition that most often presents with abnormal gastrointestinal transit and usually arises in early childhood or adolescence. Two types have been described(Type I and Type II). The adult-onset form(acquired hypoganglionosis) is extremely uncommon and is thought to arise due to cellular remodelling as a result of chronic inflammation. It differs from Hirschprung's disease in that there is a reduction in ganglion cells in the colonic neural plexuses as opposed to being completely absent.CASE SUMMARY A 31 year-old male presented to hospital with recurrent abdominal pain and vomiting over thirteen months. Abdominal computed tomography scans demonstrated thickening and stranding affecting the transverse, descending and sigmoid colon. Endoscopic appearances were non-specific but confirmed a mixed picture of mucosal inflammation and necrosis in various stages of healing.Numerous investigations were performed to elucidate an underlying aetiology but neither an infective nor ischaemic cause could be proven. Biopsy features were not typical of inflammatory bowel disease. Due to persistence of his symptoms and failure of medical management, a segmental colectomy was performed. Histological examination of the specimen revealed an unexpected finding of segmental hypoganglionosis. Complete surgical excision of the diseased segment of colon was curative and since his operation the patient has had no recurrence of symptoms requiring hospitalisation.CONCLUSION Our case serves to raise awareness of acquired hypoganglionosis as a rare condition that can result from chronic colitis. 展开更多

Acquired coronary artery fistulas(CCFs)are infrequently detected during conventional coronary angiography.To delineate the characteristics of congenital(first part)and acquired(second part)CCFs in adults,a PubMed search was conducted for papers dealing with congenital or acquired CCFs.None of the publications describing patients with coronary-vascular fistulas were included.Papers dealing with pediatric subjects were excluded.From the world literature,a total of 243adult patients were selected who had congenital(n=159/243,65%)and acquired(n=84/243,35%)CCFs.Among the acquired types(n=72,85.7%)were traumatic(iatrogenic(n=65/72,90%),accidental(n=7/72,10%)and(n=12,14.3%)spontaneously developing in relation to severe coronary atherosclerosis or myocardial infarction.A high incidence of spontaneousresolution of iatrogenic CCFs resulting from endomyocardial biopsy or following post-septal myectomy was reported.Spontaneous CCFs associated with myocardial ischemia or infarction resolved completely in 8%of the subjects.Early surgical intervention was the treatment of choice in acquired traumatic accidental CCFs.The congenital types are addressed in a previous issue of this journal(first part).In this review(second of two parts,partⅡ),we describe the acquired coronarycameral fistulas. 展开更多

Entry of acquired immune deficiency syndrome virus into the host immune cell involves the participation of various components of host and viral cell unit. These components may be categorized as attachment of the viral surface envelope protein subunit, gp120, to the CD4+ receptor and chemokine coreceptors, CCR5 and CXCR4, present on T cell surface. The viral fusion protein, gp41, the second cleaved subunit of Env undergoes reconfiguration and the membrane fusion reaction itself. Since the CD4+ T cell population is actively involved; the ultimate outcome of human immunodeficiency virus infection is total collapse of the host immune system. Mathematical modeling of the stages in viral membrane protein-host cell receptor-coreceptor interaction and the effect of antibody vaccine on the viral entry into the susceptible host cell has been carried out using as impulsive differential equations. We have studied the effect of antibody vaccination and determined analytically the threshold value of drug dosage and dosing interval for optimum levels of infection. We have also investigated the effect of perfect adherence of drug dose on the immune cell count in extreme cases and observed that systematic drug dosage of the immune cells leads to longer and improved lives. 展开更多

AIM: To investigate the effects of micro-injection of botulinum toxin A(BTXA) on acute acquired comitant esotropia(AACE). METHODS: A total of 33 AACE patients who underwent BTXA micro-injection at Renmin Hospital of Wuhan University from September 1^(st), 2019 to July 1^(st), 2021 were retrospective analyzed. Esotropia, eye alignment, stereopsis, and complications were examined at baseline(except complications), 1wk, 1, 3, and 6mo after injection. RESULTS: The average angle of deviation before injection was(+20.24±6.80)^(Δ) at near and(+24.76±6.43)^(Δ) at distance, while(+5.15±5.85)^(Δ) at near and(+7.30±6.17)^(Δ) at distance 6mo after treatment(P<0.05). Six months after injection, the stereopsis of patients had improved. The number of patients having no stereopsis(>800 seconds of arc) decreased from 11 to 3. The number of patients having peripheral stereopsis(300-800 seconds of arc), macular stereopsis(70-200 seconds of arc) and central concave stereopsis(≤60 seconds of arc) increased from 10 to 11, 10 to 12, and 2 to 7, respectively. At the follow-ups at 1wk, 1, 3, and 6mo after injection, success rates were 96.97%, 96.97%, 93.94% and 87.88%, respectively. One week after injection, two patients(6.07%) showed subconjunctival hemorrhage;three patients(9.09%) showed limited eye movement and one patient(3.03%) showed mild vertical strabismus. All the symptoms disappeared by the final follow-up.CONCLUSION: Micro-injection of BTXA can reduce diplopia and improve binocular vision function of AACE patients. Furthermore, the operation is relatively safe with few complications, making it an ideal treatment modality for AACE. 展开更多

The original and postnatal scale patterns of guard hairs were compared. The comparisons illustrate that acquired morphological changes take place in the scales on the coarse section of guard hairs, Scales on this part changes from regular smooth to irregular wave. The primary reason would be friction. Scales on the lower part of guard hairs are thick and strong to bear friction. Additionally, they are berried in the bottom layer of pelage where friction is avoided. Scales on the coarse section are thin. broad. dense and overlap, and exposed in the environment as a cover of pelage. So friction always happen on them, Factors which enhance coefficient of friction and weaken keratin bonds are combined to damage hair scales. The results suggest that regular smooth and irregular wave are actually the same type exhibiting the same origin morphological characters, so they should be counted togather in the species identification. 展开更多

Acquired DP(ADP) occurs when a peptic ulcer erodes and creates a fistula between the duodenal bulb and the distal stomach. The clinical features and endoscopic characteristics of four patients with ADP were reviewed and compared with previously reported cases. An accessory channel connects the lesser curvature of the prepyloric antrum with the duodenal bulb, and in all cases, a peptic ulcer was located in or immediately adjacent to the accessory channel. In one of the patients, the bridge between the double-channel pylorus disappeared, resulting in a single large opening and duodenal kissing ulcer after two years and three months. Finally, nonsteroidal anti-inflammatory drugs, Helicobacter pylori and other risk factors associated with ADP are assessed. 展开更多

BACKGROUND Acquired factor V deficiency is a rare secondary hemorrhagic disease,which can lead to a severe bleeding disorder.CASE SUMMARY We report a 47-year-old hemodialysis patient who presented with severe hemorrhagic pleural effusion and hemorrhagic pericardial effusion associated with lymphatic leakage.The laboratory examination revealed decreased factor V activity (2% of population average value).With decreased lymphatic leakage,factor V activity increased (to 46%).Lymph drainage correlated with prothrombin time and active partial thrombin time.The cause of the disease favored an acquired disease.The common causes which trigger factor V inhibitors were excluded.An inhibitor was not detected.It is possible that there was a clotting factor inhibitor leaking with the lymph in the drainage.Inhibitor production may be due to immune dysfunction caused by persistent lymphatic drainage,or that coagulation inhibitors were produced,drained with the lymph,and partly cleared by hemodialysis.CONCLUSION In this case,we have firstly reported factor V deficiency associated with lymphatic leakage in a hemodialysis patient. 展开更多

BACKGROUND: To explore the clinical manifestations, diagnosis, and treatment of patients with acquired immunodeficiency syndrome(AIDS) complicated with drug-induced erythroderma.METHODS: The clinical data of 12 AIDS patients with drug-induced erythroderma in our hospital were retrospectively analyzed. The general information, offending medications, complications, modified severity-of-illness score for toxic epidermal necrolysis(SCORTEN) scores, and disease outcome spectrums were analyzed.RESULTS: Drug-induced erythroderma was mostly caused by antiviral drugs, antituberculosis drugs, antibiotics, traditional Chinese medicine, and immune checkpoint inhibitors. The spectrum of sensitizing drugs was broad, the clinical situation was complex, and infections were common. The affected areas were greater than 40% body surface area in all patients. The modified SCOTERN score averaged 3.01±0.99. All patients were treated with glucocorticoids, and nine patients were treated with intravenous immunoglobulin(IVIG) pulse therapy at the same time. The average time to effectiveness was 7.08±2.23 days, and the average hospital stay was 17.92±8.46 days. Eleven patients were cured, and one patient died of secondary multiple infections, who had a modified SCORTEN score of 5 points. The mortality rate in this study was 8.3%.CONCLUSIONS: The clinical situation of AIDS patients with drug-induced erythroderma in hospitalized patients is complex and the co-infection rate is high. The use of modified SCORTEN score may objectively and accurately assess the conditions, and the use of glucocorticoid combined with IVIG therapy may improve the prognosis. 展开更多
