Challenges in Diagnosis of Neurosarcoidosis

Mar 2024 DOI 10.14302/issn.2694-1201.jsn-22-4184
Ekladious AdelCorresponding author

Sarcoidosis is granulomatous autoinflammatory autoimmune remitting relapsing disease affecting every organ in the body, it is the most difficult disease to diagnose in the absence of serum or imaging biomarker. Differential diagnosis is broad which included inflammatory, infective, neurodegenerative and neoplastic, histological biopsy is the only confirmative marker, and even histological confirmation is not robust as infection, malignancy and some drugs can induce granuloma, the most common organs affected are lung, lymph nodes, skin, eyes, liver, and less commonly pituitary gland, bones, brain, peripheral nerves, and heart, causing bilateral hilar lymphadenopathy, granulomatous lymphadenitis.

A Review on Monkey Pox: Role of One Health Approach Against Monkey Pox

Oct 2023 DOI 10.14302/issn.2641-4538.jphi-23-4622
Geinoro Alleyo TarikuCorresponding author

The Ortho-poxvirus virus, which causes monkey pox, is a member of the Poxviridae genus. It was initially found in primates. In 1970, the Democratic Republic of the Congo reported the first instance of monkey pox. From there, it spread to a number of countries both inside and outside of Africa. There are two genetic varieties of monkey pox, which have been spread to people through respiratory droplets, and touch with objects contaminated by an affected person and consequently is often encountered in work situations. Among the countries with the worst effects are Nigeria and the Democratic Republic of the Congo. Non-human primates, rats, squirrel, and or mice are just a few of the creatures that can become infected by monkey pox. Although the origins of monkey pox infections are unknown, rodents from Africa and non-human primates like monkeys may contain the viruses and infect humans. Monkey pox is more likely to naturally infect rodents. Monkey pox has symptoms and lesions that are difficult to distinguish from smallpox in its clinical manifestations. Fever, chills, migraines, tiredness, tonia, swollen lymph nodes, back pain, and myalgia are some of the clinical symptoms of monkey-pox. A few examples of diagnostic tests include immune-fluorescent antibody assays, enzyme-linked immune-sorbent assays, and real-time polymerase chain reactions. A specialized vaccine that offers complete protection against by them on key-pox virus exists, yet there is no specific therapy for human monkey infection and interaction with the vaccinia virus. Smallpox vaccination can give cross-immunity with partial protection against infection and a reduction in symptom severity. Unfortunately, community health effects in the view of one health approach has not been addressed in vast. Therefore, the objectives of this review paper are to discuss the community health effects of monkey pox and to emphasize the role of one health approach against monkey pox.

In bovine tuberculosis (bTB), cellular, humoral, or both types of immune responses have been observed. The purpose of this study was to examine the immune status of tuberculous cows based on the differential cytokine gene expression associated with Th1 (IFN-γ, IL-2), or Th2 (IL-4, IL-10) responses. Twenty-three (23) cows belonging to a dairy herd located in a rural region of the State of Hidalgo, México, were selected for the study. Single Intradermal Comparative Cervical Tuberculin (SICCT) Test, Interferon-Gamma (IFN-γ) Release Assay (BOVIGAM), and Enzyme-Linked Immunosorbent Assay (ELISA) were used for detection of cattle infected by M. bovis. Thirteen cows were positive to all the tests (Group 1); ten cows were positive only to ELISA (Group 2), and the remaining Group (Group 3, control) included cows negative to all the tests. Peripheral blood mononuclear cells (PBMC) from animals were in vitro stimulated by bovin purified protein derivative (PPD), avian PPD, and Concanavalin A (Con A) mitogen for 72h. Changes in the levels of expression of mRNA of the respective cytokines was measured by Reverse Transcription-Polymerase Chain Reaction (RT-PCR) using β-actin gene as internal control. In group 1, PPD bovis and Con A-stimulated cells exhibited high production of IFN-γ, IL-2 and IL-4, but not IL-10. In contrast, PPD avium-stimulated cells displayed a low production of cytokine transcripts. In group 2, cells showed a significant production of IL-10 in response to bovine PPD (P< 0.001). In the control group, a high production of IFN-γ and IL-2 was observed only in Con A-stimulated cells. Post-mortem examinations in animals of group 1 showed slight and medium lesions in lymph nodes, whereas in group 2, the lesions were more extensive. Results indicate differences on gene expression levels of cytokines considered to determine balance in Th1/Th2 response among the evaluated groups. In addition, high levels of antibodies against M. bovis and high IL-10 expression in PBMC together are indicators of progressive bTB when both tuberculin test and IFN-γ assay are negative in tuberculous anergic cattle. Inclusion of serology and IL-10 cytokine expression in in the diagnosis checklist improves detection of infected cattle to help control bovine tuberculosis.

This article has been retracted on March 01, 2021. VIEW THE RETRACTION NOTICE (https://openaccesspub.org/jsce/article/2243) Background Apis Mellifera L venom (Honeybees) is potent and safe anticancer drug. The present case is Basal Cell Carcinoma (SBCC), recurrent and invasde the skin of head (upper right, in front of the right ear). The patient was 65 years old in time of first intervention and the origin of BCC was primarily seen as abnormal growths and changes in birth mole on right side of head. Materials & Methods Preparation Bee Venom solution: Bee venom powder (crude) of dose 1gm was dissolved in 1000 ml of sterile distilled water then filtered by 0.22 micron syring filter. That final concentration of the stock bee venom become 1 ug /ml (i.e. 1ul=1 ug), and kept at -20◦C. (1mg (dried BV) + 1ml (water) = Final concentration (1ug/1 ul)). Before this novel intervention, allergy test performed by subcutaneous injection of small dose of bee venom (0.1 ml) and wait for at least one hour. The patient was not hypersensitive to honeybees’ venom. First stage of treatment: 1- Syringe of 1ml volume was used for direct local injection of cancer area by 0.3 ml from prepared Honeybees venom (0.1 % conc.). 2- At the same time, subcutaneous injection of 0.5 ml of bee venom solution infiltrated around the affected ear. 3- Topical application of the bee venom ointment 2% (bee venom in Vaseline) inside affected ear to protect the ear drum. This process repeated daily with cleaning of the ear every time by suitable safe and sterile saline solutions. 2nd stage: daily S/C injection in axillary area upper lymph nodes of 0.3 ml / bee venom ‘total doses 0.6 ml BV’ (left & right). 3rd stage: bee venom dissolved in sterile Clove oil was applied on inner ear above the drum. 4th stage: Management of healing process was enhanced by ascorbic acid solution as topical application on dead cancer cells and to help in removal of exudates and debris. Results The complete removal of malignant growths in affected ear achieved after 1 month from first bee venom injections. However; the cancerous areas under the second surgical intervention were treated during the next month. Conclusions Apis Mellifera L venom as anticancer drug is totally different from using direct stings as a method of Apitherapy, that because collection of bee venom lead to evaporating of most allergic substance that present in bees stings, also it can be used per os in people who exhibit different degrees of allergy against the drug safely.

Investigation of Neoplastic Cells in the Bone Marrow of Female Dogs with Mammary Gland Tumors

Jul 2020 DOI 10.14302/issn.2575-1212.jvhc-20-3434
R.R. Moreira PamelaCorresponding author

Background The mammary glands are the second most common tumor development site in female dogs. One of the ways of staging such tumors is to evaluate the presence or absence of distant metastasis, including in bone marrow. Such findings in human medicine are associated with poor survival of women with breast tumors. However, in veterinary medicine, this clinical staging is used more for patients with lymphomas and mastocytomas. Studies using bone marrow biopsies as a staging method for mammary tumors are scarce. Objectives The present study was to evaluate mammary lesions and bone marrow in 23 female dogs, searching for disseminated tumor cells or metastatic foci. Results: Grade I carcinoma in mixed tumors was the type most observed (22.4%), and there was no statistical difference in relation to tumor size or presence of metastasis in lymph nodes. In the bone marrow of one female dog with carcinosarcoma (4.35%), there was cytoplasmic marking of a probable disseminated tumor cell of epithelial origin, and immunohistochemical evaluation showed presence of cytokeratin-19 antibodies. None of the female dogs presenting reduced cellularity or medullary fibrosis, confirmed through Masson’s trichrome technique, had cell marking in immunohistochemical analyses. Conclusions Bone marrow evaluation can be used as a staging method for mammary gland tumors in female dogs, since disseminated tumor cells present the potential to become secondary lesions and to disseminate to distant foci, thereby causing tertiary metastases over an indeterminate period of time.

A Case of Collision Tumor of MALT Lymphoma and Poorly Differentiated Adenocarcinoma Diagnosed Incidentally After Appendectomy for a Clinical Presentation of Acute Appendicitis.

T KaraCorresponding author Department of Pathology, Mersin University Medical School, Mersin, Turkey

This report presents a case of collision tumors of low-grade B-cell lymphoma and poorly differentiated adenocarcinoma in the caceum of a 63-year-old woman. Lymphoma was diagnosed incidentally after appendectomy for a clinical presentation of acute appendicitis. Imaging follow-up demonstrated mesenteric lymphadenopathy and liver lesions, and all surgically resected regional mesenteric lymph nodes and liver biopsy were found to be infiltrated by both mucosa-associated lymphoid tissue (MALT) lymphoma and adenocarcinoma. Systemic chemotherapy was administered for advanced colonic adenocarcinoma with liver metastases. The occurrence of synchronous lymphoma and adenocarcinoma of the colorectal region is rare, and this is a previously unreported case of a patient that was diagnosed during management of acute appendicitis.

Background: Triple Negative Breast Cancer (TNBC) is a type of breast cancer with very bad prognosis. Predicting the histological grade (HG) and the lymph nodes metastasis is crucial for developing more suitable treatment strategies. Methods: We present the main clinical and pathological variables to predict the histological grade and lymph nodes metastasis via novel machine learning techniques. These variables are currently being used for prognosis and treatment in medical practice. This analysis was performed using a database of 102 Caucasian women diagnosed with TNBC. The results were cross-validated using random simulations of this dataset. Results: HG was predicted with an accuracy of 93.8% using a list of 6 prognostic variables with significant implications: Ki67 expression, use of Oral contraceptives, Col11A1 expression, Col11A1 score, E-cad truncated and Tumor size. The lymph nodes metastasis was predicted with an accuracy of almost 85% using only 6 prognostic variables: Vascular invasion, Tumor size, Perineural invasion, Age at diagnosis, Ki67 expression, and Col11A1 score. This analysis also served to establish the median signatures of the groups with and without lymph node metastasis, and proved the existence of a kind of small-size tumors (around 2.15 cm) with lymph node metastasis but not showing vascular and perineural invasions and higher protein Col11A1 score. Besides, these signatures proved to be very stable. Conclusions: The additional information conveyed by the prognostic variables found in these two classification problems provides new insight about the genesis and progression of this disease and can be used in medical practice to improve decisions in patient diagnosis and further treatment.

Introduction: Ultrasound study of locally advanced gastric cancer that has spread to adjoining tissue and lymph nodes. This tumor can be associated with T2 to T4 stages of cancer. A “Locally advanced gastric cancer” is a tumor, which may be categorized as ‘resectable’ cancer when compared with M1 advanced cancer. Objective: The aim of this study was to evaluate the Capabilities of transabdominal ultrasonography in assessment of structures and functional disorders of the locally advanced gastric cancer of diverse localization Materials and Methods: A total of61 patients with locally advanced gastric cancer were analyzed of which 36 (59,0%) were males (mean age 62.7 years) and 25 (41,0%) were females (mean age 59.3 years). All patients were managed surgically and underwent preoperative X-ray, virtual gastroscopy techniques, multidetector computed tomography and transabdominal ultrasonography (USG). Histopathology results found, in 58 (95,1%) cases adenocarcinoma, in 3 (4,9%) – ring-cell carcinoma (cricoidal) gastric cancer was established. Stage T2 was diagnosed in 16 (26.2%) cases, T3 - in 41 (67.2%) cases, T4 - in 4 (6.6%) cases. The stomach tumor in 29 (47.5%) cases was localized mainly in the antrum, 27 (44.3%) – in the body, 5 (8.2%) in the cardia and fundus (Table 1). In 24 (39,3%) cases, pyloric stenos was diagnosed - of which in 6 (9,8%) it was compensated, in 18 (29,5%) - sub compensated. All patients underwent preoperative X-ray, virtual gastroscopy techniques, multidetector computed tomography and transabdominal ultrasonography (USG). Normal ultrasound features were observed in 35 patients without gastric pathology. Ultrasonography was carried out with the convex and micro convex transducers in the frequency range of 2-5 MHz and 4-7 MHz respectively in B and color Doppler modes. Results: The polypoid type of gastric cancer was detected in 3 (4,9±2,8%) cases, the ulcerative type – in 18 (29,5±5,8%), the infiltrative ulcerative type – in 27 (44,3±6,4%) and the diffuse infiltrative type – in 13 (21,3%±5,2%) cases respectively. In 24 (39,3%) cases, pyloric stenos was diagnosed - of which in 6 (9,8%) it was compensated, in 18 (29,5%) – sub compensated. The layers of the gastric wall were not differentiated in all patients with sub compensated pyloric stenos. The gastric wall thickness of the affected area was 10,2±2,9mm in the case compensated pyloric stenosis, the length was 27,1±6,2mm, the diameter of the pylorus was 8,3±0,8mm. Among patients with sub compensated pyloric stenos, the thickness of the gastric wall was 19,8±4,1mm, the length was 43,6±4,5mm, the pyloric diameter was 4,3±1,1mm. Among the 61 patients studied, pathological vascularization was detected in 42 (68.8%) cases. It was observed that, all 4 (6.5%) patients with gastric cancer were stage T4 and 38 (62.3%) were stage T3. Vascularization was weak in 13 cases, in 24 cases - moderate, and in 5 cases - enhanced. Metastases to the regional lymph nodes were diagnosed in 52 cases. Ultrasonographically, they were detected only in 37 (71.2%) cases. Conclusions: In the diagnosis of locally advanced gastric cancer, ultrasonography demonstrates good capabilities for determining the extent and depth of the affected area. Color doppler mode allows the study of vascularisation of a locally thickened area, as well as nearby enlarged lymph nodes, which is very important to ascertain the degree of malignancy of the hyperplastic process. ltrasonography can independently determine the degree of pyloric stenosis in patients with distal gastric cancer.

Study of VCAM-1 Gene Expression in Normal and Tumoral Tissues in Patients with Colorectal Cancer

Aim: Colorectal cancer is one of the most commonly diagnosed cancers in the world. Cell adhesion molecules play an important role in the progression of various cancers. It has been shown that the high level expression of some Cell adhesion molecule could be a new diagnostic factor for several cancers. Vascular cell adhesion molecule 1(VCAM1) is a cell surface glycoprotein that is expressed in the endothelium activated by cytokine. Generally, VCAM-1 expression level is very poor in normal adult tissue endothelial cells. According to the above explanation, this study was conducted to investigate the expression of VCAM-1 in tumoral tissues and adjacent normal tissues in Iranian colorectal cancer patients to its relation with clinicopathological Features in patients with cancer. Methods: In this study, 60 tumoral tissues and 39 adjacent normal tumor tissues were evaluated using reverse transcription-polymerase chain reaction (RT-PCR) technique. Conclusion: A significant correlation was found between VCAM-1 expression level and the stage, lymph nodes involvement, tumor progression factor of cancer and sex. Interestingly, VCAM-1 expression not observed in tumors with stage0. No association was seen between VCAM-1 expression and other clinical features such as age, size of the tumor, metastasis and the number of lymph nodes. These findings suggest that VCAM-1 expression level may reflected disease progression and elevation in VCAM-1 has prognostic significance in patients with colorectal carcinoma.

Status thymico-lymphaticus had ever been explained as a cause of sudden death usually in children, but few cases were reported in adults. We sought to determine the relationship between thymic hypertrophy and sudden unexpected death in adult (SUDA), and associated macroscopic and microscopic findings. Adult post mortems from 1984 to 2014 were reviewed and 23 thymic hypertrophy patients without SUDA, 33 thymic hypertrophy patients with SUDA and 172 SUDAs without thymic hypertrophy entered. The data of thymus, lymph nodes, spleen, heart, aorta, and adrenal glands were collected for macroscopic and histological analysis. Ten antibodies were used and applied to 3 children and 46 adult thymus specimens. We found, as an independent factor, thymic hypertrophy increased significantly the risk of SUDA (6.9 folds) in both male and female. What’s more, SUDAs associated with thymic hypertrophy were quite younger (22.5 years) than those without it. A majority of patients with hypertrophic thymus had a variable number of accompanied anomalies described as the typical characteristics of status thymico-lymphaticus, but no macroscopic and microscopic findings related to SUDA in patients with thymic hypertrophy. Cytokeratins (CKs) showed distinctly different immunohistochemical expression patterns in individuals who had different death causes and disease background. Instead of a disease entity “status thymico-lymphaticus” is a systematic abnormality with thymic hypertrophy as a feature involving mainly immune and/or cardiovascular system, probably caused by gene mutations.

Adenosquamous Cell Carcinoma of the Stomach 18F-FDG PET/CT Diagnosis and Review of Literature

Nov 2016 DOI 10.14302/issn.2574-4526.jddd-16-1311
M DarouichiCorresponding author Department of radiology

Adenosquamous carcinoma of the stomach (ASCS) is extremely rare with less than one hundred cases published in the world literature. It is defined by combined adenocarcima and squamous cells carcinoma of the stomach. ASCS is clinically aggressive and has a poor prognosis, even when discovered at an early stage. This intriguing entity is characterized by non specific symptoms or radiological signs. Integrate 18F-fluorodeoxyglucose positron emission tomography/computed tomography 18F FDG.PET/CT is useful morphologic and functional modalities for evaluating primary tumor, local extend and invasion beyond gastric wall or distant metastatic and eventually for management. Diagnosis of ASCS requires immunohistochemical confirmation. We report a 77-year-old man who was admitted to hospital because of epigastric pain, vomiting and melena since more than a month. Gastroscopy with biopsies had initially suggested gastric squamous cell carcinoma .Thoracic and abdominal computed tomography scan (CT) showed a huge mass in the gastric body, largely necrotic, infiltrating the adjacent structures without metastases. Partial gastrectomy with resection of the proximal 2/3 of the stomach, the spleen, the body and tail of pancreas and the left transverse colon was performed. Immunohistochemical analysis demonstrated ASCS with mixed adenocarcinomatous and squamous cells carcinoma with invasion of gastric lymph nodes. Unfortunately, two months after surgery, a CT of the abdomen revealed diffuse metastasis and the patient died three months later. In light of this case, we discuss the pathogenesis, staging and monitoring of this rare entity by combined 18F-FDG PET/CT with review of the literature.
