Objectives The number of cases of cyanoacrylate closure (CAC) system for varicose veins has been increasing worldwide. However, as this is a new treatment method, the potential adverse effects and other details remain unclear. In particular, the cause of inflammation in embolized veins is still under debate. Methods We performed a drug-induced lymphocyte stimulation test (DLST) on a patient with allergic-like symptoms after CAC. Results The DLST was strongly positive in this case, and the patient underwent total removal of the CAC-filled vein due to difficulty controlling the symptoms with medication. After that the state was recovered and no medication was continued. Conclusion We encountered a case that a delayed allergy by CA after CAC treatment developed in, eventually leading to the total removal of the CA-filled vein. It was suggested that with doubting allergic-like symptom after CAC, DLST for CA could show not only the diagnosis of the delayed allergy to CA, but also the later treatment policy with stimulation index (S.I.) in the positive cases.

Aim: The relation between inflammation and cancer has been known since the 19th century. However, investigations on the pathogenesis and pathophysiology of this relation have begun recently. It was demonstrated that increased neutrophil/lymphocyte ratio is a poor prognostic factor in some malignancies. The present study aimed to determine whether preoperative neutrophil/lymphocyte ratio has a prognostic value in larynx cancer. Method: Preoperative blood analyses of 139 patients, who underwent subtotal or total laryngectomy for larynx cancer between 2003 and 2013 at Marmara University School of Medicine, Department of ENT, were retrospectively evaluated. Neutrophil/lymphocyte ratio (NLR) was calculated dividing absolute neutrophil count by absolute lymphocyte count. Optimal cut-off value for NLR was determined by receiver operating characteristics (ROC) curve analysis. Statistical analyses were done using IBM SPSS statistic 22.0 (IBM SPSS, Turkey) and Med Calc 12.3.0 package programs. Results: The sensitivity of NLR in predicting advanced-stage (Stage 3 and 4) squamous-cell carcinoma of the larynx (LSSC), T4 LSSC and lymph node metastasis at different cut-off values were 66.2%, 83.9% and 73.8%, respectively and the specificity was 76.7%, 66.2% and 65.2%, respectively. Staging according to T classification revealed that NLR significantly increases with tumor stage (p<0.001). Statistically significant relation was determined between lymph node metastasis of tumor and neutrophil/lymphocyte ratio (p=0.003). Comparing overall survival (OS) and disease-free survival (DFS) between the cases with NLR <3.02 and the cases with NLR >3.02, it was demonstrated that OS and DFS are significantly lower in the cases with NLR<3.02 (p: 0.001 vs. p<0.05 for OS and p: 0.013 vs. p<0.05 for DFS) Conclusion: NLR increases with the stage of disease in LSSC. NLR is a simple, cheap, repeatable and valuable parameter that can be obtained from routine analyses, gives information about poor prognosis and survival, and is able to predict T4 LSSC, advanced-stage LSSC (stage 3-4) and lymph node metastasis.

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a known side effect of several oncology drugs, but it is rarely seen secondary to vinblastine with only a few cases reported worldwide. Herein we present a patient with nodular lymphocyte-predominant Hodgkin disease that developed a severe acute hyponatremia seven days after her first cycle of chemotherapy with R-ABVD. After fluid restriction, symptoms and concentration of blood sodium were restored. After a comprehensive review of the literature vinblastine was thought to be the cause and avoided in the second infusion of chemotherapy without recurrence of the SIADH.

Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection often causes coagulation disorders that affect highly vascularized organs, such as the lungs and kidneys. Objective The objective of this study was to report the histopathological findings of variations in the fibrin pattern of pulmonary and renal microthrombi in patients who died from SARS-CoV-2 infection. Methods Minimally invasive autopsies were performed on 40 patients to collect lung (n=40) and kidney (n=16) tissue samples. Histochemical and immunohistochemical staining techniques were used for histopathological analyses. Premortem laboratory data were obtained from the patients' electronic medical records. Results The lung tissue showed a patchy pattern, characterized by areas of both minimal and severe damage. The most significant histopathological finding was the detection of thrombi with fibrin structures organized into discrete star-shaped units, which were more frequently observed in areas with severe lung injury than in those with minimal lung injury (p = 0.012). Star-shaped fibrin structures were also observed in the renal glomerular capillaries. Immunohistochemical staining revealed the presence of platelets and the procoagulant proteins von Willebrand factor (VWF) and Factor VIII within the star-shaped fibrin thrombi. Patients with star-shaped fibrin thrombi had higher levels of the systemic inflammatory indicators C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR). Conclusion Our observations suggest that the inflammatory microenvironment resulting from SARS-CoV-2 infection may contribute to the formation of star-shaped fibrin units in the pulmonary and renal microthrombi.

Objective To study changes of cell morphology in BALF in children with Mycoplasma pneumoniae pneumonia (MPP). Methods From December 2021 to May 2022, a group of 32 children diagnosed with Acute MPP and admitted for treatment in the Pediatrics Department and PICU of the First Affiliated Hospital of Xinxiang Medical University were selected for our study. These patients underwent bronchoalveolar lavage as part of their clinical assessment. For comparison, we included a control group comprising 10 children who were not infected but had bronchial foreign bodies. We investigated the cellular composition in the bronchoalveolar lavage fluid (BALF) using Wright-Giemsa staining and microscopic evaluation, aiming to understand the relationship between shifts in cell proportions and extra-pulmonary symptoms associated with MPP. Results In this study, a total of 42 cases were enrolled, with 32 cases in the study group and 10 cases in the control group. There were no statistically significant differences in gender, age, height, weight, and BMI between the two groups (p > 0.05). The study group exhibited significantly higher levels of neutrophil percentage (GRA%), CRP, D-dimer, and LDH in blood routine tests compared to the control group (p < 0.05). Furthermore, the proportions of neutrophils (%) and macrophages (%) in BALF were significantly higher in the study group compared to the control group (p< 0.05), while the proportion of lymphocytes (%) in BALF showed no statistically significant difference between the two groups (p> 0.05). Conclusion In the acute phase of MPP in children, BALF is predominantly composed of neutrophils. A lower proportion of lymphocytes in BALF is associated with a higher incidence of extra-pulmonary manifestations and longer hospitalization duration.

Dermatophytosis affect companion animal’s skin and keratin appendages as cats and dogs, resulting in red, scaly, itchy, bald, and raised patches like ring. The three main groups are Microsporum, Trichophyton and Epidermophyton. This study collected samples of skin scrapping and hairs from 130 cats and 70 dogs, using common mycological approach samples were examined. Antifungal agar disc diffusion and broth microdilution assays were utilized on some of the isolates. Three groups of Guinea pigs (6 in each) were then infected with one isolate of M. canis or T. mentagrophytes fungi, another skin scrapping samples of virulent fungi was isolated on the 7th and 14th days, blood samples were collected at 14th day. Reverse transcription-PCR to detect 98 bp protease gene. Resulting in 45% of cats and dogs tested positive for Microsporum and Trichophyton species. Agar disc diffusion revealed that the antifungal medication griseofulvin was the most effective against tested isolates. The best results for MIC test were griseofulvin (0.98 µg/ml) followed by acetic acid (0.28 µg/ml). Differential leukocytic count of Guinea pigs showed that monocyte levels remained unchanged, while neutrophil and lymphocyte levels had increased. The active (isolates from Guinea pigs skin scrapping) and dormant cells (isolates from keratin free media) were distinguished by Reverse Transcriptase-PCR. Collectively, qPCR is a successive and feasible method for the diagnosis for Microsporum and Trichophyton species.

Background Ageing is a life process in which progressive molecular, cellular, physiological and anatomical changes manifesting in humans and animals including other organisms lead to the decline of biological functions. Immunoglobulins (Igs) are glycoprotein molecules produced by white blood cells mainly B lymphocytes following signal transduction as a result of their interaction with pathogenic microbes or poisonous substances introduced into the body systems. They elicit responses against the side effects of pathogens and poisons in which their response efficiency usually declines as we are ageing. Objective Thus, the similarities between Igs’ immune response against the different amounts of xenobiotics and the biological changes associated with ageing have been systematically assessed using the reports of different study results on humans and animals. Methods First, a literature search was carried out in google, PubMed and google scholar using planned search terms related to the title of this study. Review and original articles were retrieved, downloaded and saved on a computer. And then the effects of different factors i.e. xenobiotics, age, sex and lifestyle-based practices on the levels of serum Igs (IgG, IgA and IgM) in animals and humans have been studied using a systematic review of different literature sources. Finally, the relationship between the findings of various studies has been assessed and judgment on the possible cause of ageing has been made. Results The findings of different research have demonstrated that the signaling efficiency of immunoglobulin M (IgM) has been limited by the amount of test compounds administered to study Balb c mice in the oral route. The response efficiency of IgM immune response against the lower doses of test compounds were high compared to the higher doses of test compounds which was low. The results of different other studies also demonstrated that the decline of serum IgM levels was associated with ageing. The relationship between alcohol consumption and the concentration of serum Igs was also described in the report of different studies. These studies have shown that there was lower level of IgG in the blood serum of alcohol consumers compared to non-consumers. The study has also demonstrated a lower level of serum IgM with higher alcohol consumption and higher serum concentration with moderate beer consumption. Conclusion The trajectory of Igs’ immune response against different amounts of xenobiotics was highly associated with the trajectory of biological changes during ageing. These research findings might be the possible evidence to conclude that ageing is caused by the foodstuffs and non-foodstuffs we usually consume, the lifestyles we usually experience and the way of life we usually live in the environment which gradually defiling the natural processes of the body.

In Ethiopia stunting, underweight and wasting in school children are very common. The aim of this research was to evaluate the impact of intestinal helminthes and schistosomiasis on malnutrition, anaemia and haematological indices in the school age children of Azezo Elementary School in Gondar town. Kato Katz technique was performed to determine infection and intensity of intestinal helminth infections. AnthroPlus software version 1.04 was used to get malnutrition indices while fully automated haematological analyzers were used to determine haematological and biochemical parameters. A total of 384 school children were recruited in this study. The overall prevalence of helminth infection was 45.8% (178/384) with the leading Ascarislumbericoides infection (20.6%) compared to the second leading Schistosomamansoni (17.4%) and third leading hook worm infections (13.3%). The prevalences of body mass indexes for age Z-scores (BAZ) indices were 9.6% (37) very sever thin, 17.2% (66) sever thin, 38.3% (147) thin, 34.4% (132) normal and 0.5% (2) overweight. On the other hand, the prevalences of height for age Z-scores (HAZ) indices were 12.2% (47) stunt, 87% (334) normal and 0.8% (3) over height. Of the total 384 school age children, 335 (87.2%) had normal blood glucose level (70 – 110 mg/dL) while the remaining 49 (12.8%) school age children were hypoglycemic. The number of the school children with normal total protein level (6.6 – 8 g/dL) was 259 (67.4%) while the remaining 125 (32.6%) school children were hypo-proteinaemic. The prevalence of anemia in the school age children was 33.1% (127). Intestinal helminth infections were statistically significantly associated (p = 0.000) with hypo-proteinaemia, anemia and number of lymphocytes compared with non-infected school children. The likelihood of anemia in intestinal helminth infected school children, when it was compared with uninfected, was 148 times higher for both Ascaris lumbericoides-Schistosoma mansoni co-infection, 38 times for Hookworm, 20 times for Schistosoma mansoni and 3 times for Ascaris lumbericoides mono-infections. Conclusion: Intestinal helminth infections in school age children aggravate malnutrition. Prolonged malnutrition and intestinal helminth infections could result in stunting in school-age children.

Lennert lymphoma (lymphoepitheloid lymphoma) is an extremely rare variant of peripheral T-cell lymphoma, not otherwise specified. Here we report a case of Lennert lymphoma diagnosed in a 57-year-old woman. She had a three-year history of waxing and waning lymphadenopathy with a rapid increase in size in the past four months before presentation. A needle biopsy and a fine needle aspiration were non-diagnostic due to extensive necrosis. The patient underwent a right neck lymph node excisional biopsy which showed the lymph node architecture was effaced by numerous and sometimes confluent clusters of epithelioid histiocytes and infiltration of small lymphocytes. Extensive necrosis was present. Immunohistochemical stains revealed a mixed population of B- and T-cells with the T-cells showing diminished T-cell markers CD3, CD5, and CD7. Flow cytometric analysis detected a small population (7% of total lymphocytes) of CD4-positive T-lymphocytes with loss of CD3, CD5, and CD7 expressions. PCR-based T-cell receptor gene rearrangement studies showed positive results (clonal peaks) in both gamma and beta genes. Stains for microorganisms were negative. The overall findings indicate Lennert lymphoma. To our knowledge, this is the first reported case of Lennert lymphoma with extensive necrosis. The patient is undergoing chemotherapy. The diagnosis of Lennert lymphoma can be challenging, particularly in cases with extensive necrosis. Our case highlights that adequate sampling is important in the investigation of patients with suspected Lennert lymphoma. A careful pathologic examination with ancillary studies including flow cytometry, immunohistochmistry, and cytogenetic and molecular studies leads to the accurate diagnosis.

Antibodies and antibody fragments, especially single-domain antibodies known as nanobodies, are important tools in diagnostics, research, and therapeutics. In a conventional antibody, light and heavy chains contribute to the formation of the antigen binding site. In addition to conventional antibodies, old and new world camels also have heavy-chain antibodies (hcAbs), which lack the light-chain antibodies that usually bind to the antigen, as well as single domain antibodies, the VHH domain, which are the smallest antigen-binding fragments and have high solubility, stability, and specificity. A VHH library against E. coli lipopolysaccharide (LPS) was produced using the camel immune system. E. coli strains from dead camel calves were isolated to extract the LPS and used to immunize a 2-year-old female camel. After isolating mononuclear lymphocytes for RNA extraction and amplification of the VHH gene, the PCR product was cloned into the pF1AT7 Flexi vector and transformed into JM109 E. coli competent cells by heat shock, resulting in a comprehensive VHHs library with 6.9 × 104 cfu/µg. The VHHs were expressed and screened with ELISA and PCR. Eleven colonies were positive by PCR, six of which were sequenced and submitted to Genbank compared with GenBank data to confirm the production of nanobodies with a similarity >90%.

Industrial effluents containing heavy metals may reach aquatic systems either through direct discharge or surface runoff and cause damage to aquatic organisms affecting their immune system and health. Hence the present study has been undertaken to observe the effects of hexavalent chromium on the WBCs of the fresh water fish, Labeorohita. WBCs play a major role in the immune response of the fish. For acute toxicity determination, healthy fish were subjected to static bioassays. The 24, 48, 72, and 96hr LC50 values were 50.88, 42.03, 28.09 and 10.87 ppm respectively. The fish were exposed to 0.5, 1, 1.5 and 2 ppm for 20 days. Differential count of WBCs and total WBC count were determined after every five days for twenty days. Lymphocytes exhibited a decline while the other cells and total WBC count exhibited an increase due to hexavalent chromium exposure. The results were subjected to two way analysis of variance.

Obesity can be defined as a condition of abnormal or excess fat accumulation in adipose tissue, to the extent that health may be impaired. Fennel is one of the oldest spice plants which widely grows in arid and semi-arid and due to its economic importance and pharmaceutical industry usage. This plant has anti-inflammatory and analgesic effect and is effective in gastrointestinal disorder treatment. The aim of the present study was to evaluate the phytochemical characteristics and therapeutic properties of this medicinal plant. The current study demonstrates that the alteration induced by high fat diet causing changes in blood parameters. These changes are exhibited through a decrease in RBCs, Ht, Hb and platelet and these changes could be due to oxidative stress, which lead to lipid peroxidation in RBCs membranes, auto oxidation of hemoglobin. As regards the total WBCs, lymphocytes and monocytes showed marked decrease. While a distinct increase in the percentage of neutrophils and eosinophil. The present, demonstrates that rats treated with (fennel), (ator) and (fennel with ator) exposure provided significant protection to the altered hematological variables. The effect of the treatment with fennel and ator more effect than fennel only and ator only. The finding of this study indicates that the concentration of Malondialdehyde (MDA) and Myeloperoxidase (MPO) in liver homogenates of the fennel and ator group significant decrease than group (3) and group (4) and the obese group. There is a growing awareness that obesity is a prime risk factor for the development of dyslipidemia profile and that oxidative stress may play a role in various adverse effects of obesity.

Introduction: Squamous cell carcinomas of the conjunctiva (SCC) are rare neoplasia but have a high rate of increase and a high rate of mortality, especially when they occur in the context of Human Immunodeficiency Virus (HIV) infection. The objective of this study was to establish an epidemiological and clinical profile of SCC in patients living with HIV and to assess its evolutionary characteristics. Patients and Methods: this was a descriptive cross-sectional study carried out over a period of 5 years in the ophthalmology department of the University Hospital of Treichville. The data collected focused on epidemiological, clinical, pathological, therapeutic and evolutionary elements. Twenty tree eyes of 23 patients were examined during this period. Results: The average age of our patients was 45 years with extremes ranging from 31 to 60 years. A female predominance was observed with a sex ratio of 0.92. The average consultation period was 18 months with extremes ranging from 6 to 60 months. Physically, 35% of our eyes (08 eyes) presented a functional loss of the eye. All our patients had a HIV positive status with 16 cases of HIV1 infection, 4 cases of HIV 2 infection and 3 cases of HIV 1 and 2 co-infection. Lymphocyte typing was performed for 15 patients out of the 23 With CD4 cell counts ˂ 200 in 30.43% of cases, between 200 and 500 in 34.78% of cases. All our tumors had had biopsy excision with pathological examination. A postoperative adjuvant topical chemotherapy in 6 cases. The average follow-up period of our patients was 29 months. In all cases, it was invasive differentiated squamous cell carcinoma. Discussion: HIV infection is a risk factor for the occurrence of conjunctival squamous cell carcinoma, but it is also an aggravating factor especially in the case of low CD4 cell count, particularly in sub-Saharan Africa, where the fight against infection, although boosted in these recent years, is far to achieve all objectives Conclusion: HIV seroprevalence is very often associated with opportunistic infections which include carcinogenic processes such as squamous cell carcinomas of the conjunctiva

The mammary tumor is one of the most common cancer in female dogs and, at the present days, there is a big focus on the study of the relation between this kind of tumor in animals and the cells that stay around them, like the inflammatory cells. The objective of this study was to evaluate and show where the inflammatory cells stay in simple mammary carcinomas in female dogs by immunohistochemistry. Samples of simple mammary carcinomas (tumor group; n=26) and mammary gland samples without tumor (control group; n=18) were submitted to immunohistochemical analysis for the detection of T lymphocytes, macrophages, plasma cells and the MHC-II molecule. The mast cells were evaluated by the histochemical technique (toluidine blue). Lymphocytes, macrophages and mast cells were observed distributed in the tumor stroma. MHC-II was detected in tumor cells and in the inflammatory infiltrate. Plasma cells predominated in the peritumoral stroma. Macrophages differed significantly between the two groups and predominated in the tumor group. In the comparison between histological types of mammary carcinomas, mast cells differed significantly between solid tumors of the tubular / papillary types. The cytoplasmic immunodetection of MHC-II was suggested an inefficient antigen presentation. Some of the leukocytes present in the tumor infiltrate, appear to be exerting a pro-tumor effect and allowing the progression of tubular and papillary carcinomas. But in solid carcinomas (may be poorly immunogenic), as they had the lowest proportion of leukocytes present in the tumor site. More studies are necessary to confirm these results, such as the determination of the cytokine profile and the predominant leukocyte subpopulations in the tumor microenvironment.

This essay draws on recent evidences from SIV vaccination studies in rhesus macaques to argue for the potential importance of HIV-1-specific CD8+ T cells restricted by the non-classical major histocompatibility complex, HLA-E, in controlling HIV-1 replication. It then seeks to present a possible method of inducing such responses through the procedure of T cell vaccination using activated autoimmune CD4+ T lymphocytes ‘infected’ with inactivated replication-incompetent structurally intact HIV-1 particles. It is hoped that the argument presented here will interest many of those involved in HIV/AIDS research and others in the general scientific community.

Background: Studies have unveiled lower levels of serum vitamin D in autoimmune diseases and the role of vitamin D in inhibition of helper T cells proliferation, stimulation of regulatory T cells, diminishing of B-lymphocyte differentiation and inhibition of immunoglobulin secretion has been discussed in the literature. Oral lichen planus (OLP) is an autoimmune mucocutaneous disorder in which cell mediated immunity plays an important part and so it may also be related to serum vitamin D levels. Aim: To estimate serum vitamin D in oral lichen planus patients of North India, compare it to the controls and to evaluate various factors influencing vitamin D level in OLP cases such as sun exposure, gender, psychosocial factors, meteorological influences, religion and diet. Methods and Material: Venous blood samples of 102 clinically diagnosed oral lichen planus patients and 102 age and sex matched controls were obtained for the study and serum vitamin D levels were estimated using Vitek Immunodiagnostic Assay System, an automated bench-top immuno-analyzer, based on the Enzyme Linked Fluorescent Assay. The data was analyzed using chi-squared test and t-test. Results: Mean vitamin D in OLP cases and controls was 20.40 ng/ml and 32.67 ng/ml respectively. Vitamin D3 deficiency was more in OLP cases (70.6%) as compared to controls (34.3%) and insufficiency was more in controls (35.3%) as compared to OLP cases (16.7%). These differences were statistically significant. Conclusion: Although vitamin D deficiency was found more in OLP cases pointing towards the possible co-relation of vitamin D and OLP, yet insufficiency was seen more commonly in controls which revealed that this important vitamin was lacking in North Indian population.

Idiopathic sudden sensorineural hearing loss (ISSHL) is a commonly seen otorhinolaryngology emergency, and its etiology is still a mystery. In this retrospective clinical study, we aimed to investigate the possible relationship of inflammatory markers derived from CBC such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), Red cell distribution width-to-platelet ratio (RPR), lymphocyte-to-monocyte ratio (LMR), mean platelet volume (MPV) and platelet distribution width (PDW) in ISSHL . A total of 50 idiopathic sudden hearing loss patients were included in the study. They were grouped according to their hearing healing levels as recovered, partially recovered and unrecovered. Also 47 age- and sex- matched healthy individuals created the control group. Their complete blood count parameters of NLR, LMR, PLR, RPR, PDW and MPV were recorded. The results were statistically compared to bring out a significant difference between the groups. There was no significant demographic difference between the groups. The comparison of patient group with control group reveal a significant difference in the NLR, LMR and PDW values (p<0.05). The remaining values were not statistically significant. The analysis of these values according to the recovery level of the ISSHL, there was no statistical difference between the groups (p>0.05). We demonstrated for the first time that LMR value was significantly elevated in ISSHL patients. NLR, LMR, and PDW might be indicative for diagnosis of ISSHL. However, we believe that using these parameters for the screening of the prognosis is a clinically useless exercise.

Targeting cell metabolism is a therapeutic approach which has been used for the treatment of cancers with high levels of proliferation. Inhibition of metabolic processes in cancer cells has shown synergy with current therapeutic options to reduce refractory disease and relapse. In contrast, chronic lymphocytic leukaemia (CLL) is a disease where expansion of the malignant clone results from a combination of enhanced cell survival coupled with low level proliferation. The purpose of this article is to highlight how further research is needed to determine whether targeting cell metabolism may be a viable therapeutic strategy in this disease. We discuss how lymphocyte doubling time (LDT) remains a robust prognostic indicator used in the current clinical management of CLL, and how recognition of CLL as a proliferative disease has led to a greater understanding of the importance of energy-generating processes in its pathobiology. We summarize what is currently known about normal B cell metabolism and consider whether there is evidence of the Warburg effect in CLL cells. Finally, we speculate on how CLL cells may exploit protective mechanisms such as autophagy during times of metabolic stress and how they might influence or be influenced by metabolic characteristics of the microenvironment.
