Equine Granulocytic Anaplasmosis: A Systematic Review and Meta-Analysis on Clinico-Pathological Findings, Diagnosis, and Therapeutic Management.

Equine granulocytic anaplasmosis (EGA) is a tick-borne disease affecting horses worldwide, caused by Anaplasma phagocytophilum. The disease ranges from non-specific clinical signs to fatal outcomes. This paper aimed to analyze EGA cases reported in peer-reviewed journals, particularly on clinico-pathological findings, diagnosis, and therapeutic management. Overall, 189 clinical cases from 31 publications were included in the study. Extensive symptomatology for the EGA cases was reported, of which mostly was fever (90.30%), followed by limb edema (48.51%), anorexia (41.79%), depression (32.84%), icterus (22.39%), ataxia (17.91), tachycardia (16.42%), and lethargy (15.67%). Laboratory tests revealed thrombocytopenia (90.32%), anemia (75%), decreased hematocrit (70.59%), leukopenia (55.88%), lymphopenia (58.14%), and neutropenia (41.67%) as the most common hematological abnormalities. For a subset of tested animals, hyperbilirubinemia (20/29), hyperfibrinogenemia (13/15), and hyponatremia (10/10) were also reported. The diagnosis was established by microscopic identification of morulae (in 153 cases), and/or PCR (120 cases), isolation (1 case), or serology (56 cases). For treatment, oxytetracycline was used in the majority (52.24%) of EGA cases, but recovery without antibiotherapy (10.34%) was also noted. In conclusion, the variety of clinical and pathological findings and the challenging therapeutic approaches reported suggest that EGA should be included in the differential diagnosis when fever occurs.

A descriptive study of the clinico-pathological and surgical characteristics of patients with primary epithelial ovarian cancer. A cross sectional study.

OBJECTIVE: To study the clinical, pathological and surgical features of primary epithelial ovarian cancer treated at our institution. METHODS: fifty-nine patients with primary epithelial ovarian cancer were included. Clinical data collected included patient's age, presenting symptoms, laboratory and tumor markers results as well as preoperative imaging reports. Pathological and surgical findings included were: spread of the disease, histologic type, stage of the disease, type of surgical procedure and amount of residual disease. RESULTS: Mean age of the patients was 54.5 years. Lower abdominal pain was the most common presenting symptom, followed by abdominal distension. The commonest histopathological type was high grade serous carcinoma (72.9%). In our study, majority of patients were diagnosed with stage III disease, accounting for 69.5% of the total number of patients. Complete cytoreduction with no gross residual disease was achieved in 77.3% of patients with stage 3-4 disease. CONCLUSION: clinical and pathological features of primary epithelial ovarian carcinoma in our populations are similar to what is reported worldwide. We have also documented that our surgical approach to the management of ovarian cancer is comparable to the international consensus.

Safety evaluation of Ochratoxin A and Citrinin after 28 days repeated dose oral exposure to Wistar rats.

Mycotoxins, ochratoxin A (OTA), and citrinin (CTN) are toxic metabolites of filamentous fungi. The most common fungal species that produce OTA and CTN belong to genera Aspergillus, Penicillium, Fusarium, and Monascus, and these fungal species are found to be contaminant a wide range of grains, food, and food product. The aim of our study was to evaluate the sub-acute repeated dose oral toxicity of OTA and CTN in experimental rodents by following OECD test guidelines for testing chemicals no. 407 with minor modifications. Twenty-five rats of each sex were divided equally into five groups; vehicle control, OTA 25 µg/kg b. wt., OTA 100 µg/kg b. wt., CTN 25 µg/kg b.wt. and CTN 100 µg/kg b. wt. The results of this study showed no abnormal clinical signs during 28 days of the experimental period. We did not found any significant changes in body weight gain, food consumption pattern, organ weight, hematology except few parameters, and biochemical values in any of the treatment and control groups. However, histopathological observations revealed severe nephrotoxicity and mild follicular depletion in the spleen of 100 µg/kg b. wt. treated groups of both OTA and CTN mycotoxins. The findings of our study are of its first kind that reports the systemic toxicity of OTA and CTN oral exposure to laboratory rodents.

Clinical Occurrence of Canine Babesiosis in the Coastal Area of the Black Sea (Dobrogea) in Southeastern Romania and Associated Epidemiological Implications.

Canine babesiosis (CB) is a significant tick-borne disease caused by intra-erytrocytic protozoa of the genus Babesia (Apicomplexa: Piroplasmida) and is currently emerging or re-emerging in many European countries. Despite the increasing incidence of clinical CB, little is known of the epidemiology of this disease in Romania. Therefore, the present study was conducted to provide epidemiological data on CB in the coastal area of the Black Sea (Dobrogea), southeastern Romania. For this, 306 owned dogs presented during 2016-2018 at a veterinary clinic in the area and clinically suspected for CB were tested for the presence of intra-erytrocytic piroplasms using Giemsa-stained thin blood smears. Overall, 27.8% (95% CI: 22.83-33.16) of dogs were positive for large piroplasms. The Babesia spp.-positive dogs were 51 males and 34 females aged from 3 mo to 13 yr (mean 4.2 yr; SD = 3.6). A higher rate of infection was registered in Bichon Maltese (n = 13) and mixed-breed (n = 28) dogs. Most cases (76/85; 89.4%) were diagnosed from March to June, with only a few cases registered in November and December (1 case each). Infected dogs displayed different clinical presentations, varying from mild (38.8%) to moderate (29.4%) and severe disease (29.4%). Based on clinical- pathological changes, 38 (44.7%), 34 (40.0%), and 13 (15.3%) dogs were diagnosed with uncomplicated babesiosis, complicated babesiosis with a single organ dysfunction, and complicated babesiosis with multiple-organ-dysfunction syndrome (MODS), respectively. The recovery rate (81.6%, 70.1%, and 38.4%, respectively) was significantly different in these groups. The age of dogs appeared to be a risk factor for both severe disease (mean age of 5.8 yr) and MODS (mean age 6.8 yr). These findings document the common occurrence of CB in Dobrogea, southeastern Romania, and suggest that appropriate control measures need to be taken.

CLINICO-PATHOLOGIC REVIEW OF BIOPSIED TONGUE LESIONS IN A NIGERIAN TERTIARY HOSPITAL.

BACKGROUND: Varying pathologic conditions can affect the tongue for which the pattern of occurrence may differ. The aim of this study was to review the clinico-pathologic features of histologically diagnosed cases of tongue lesions that presented in our hospital over a 21 years period. MATERIALS AND METHODS: Data on habits, class of lesion, histological diagnosis, age, gender, and site distributions were analyzed using descriptive frequencies, ranges and means ± SD. Variables were compared using Chi square and ANOVA tests as appropriate. Sites of lesions were coded using the WHO ICD-O code on topography. RESULTS: Tongue lesions were seen in 43 males and 31 females. There was a bimodal peak age of occurrence at 40-49 and 60-69 years of age. Smoking and alcohol intake habits were recorded in 8 cases only. Neoplastic lesions constituted 78.4% of the cases. Using the WHO ICD-O code for topography of lesions, the tongue dorsum (ICD-O-2.0) was the most commonly affected site. Malignant lesions constituted 47.3% of the cases seen. Also, 8.6% of the malignant lesions were seen in younger patients (< 40 years). CONCLUSION: Tongue lesions showed a bimodal age of occurrence with neoplastic lesions as the most histologically diagnosed lesions in our study.

Clinico-pathology and hemato-biochemistry responses in buffaloes infected with Pasteurella multocida type B:2 immunogen outer membrane protein.

The aim of this study was to investigate the clinico-pathology and haemato-biochemistry alterations in buffaloes inoculated with Pasteurella multocida type B:2 immunogen outer membrane protein via subcutaneous and oral routes. Nine buffalo heifers were divided equally into 3 treatment groups. Group 1 was inoculated orally with 10 mL of phosphate buffer saline (PBS); Group 2 and 3 were inoculated with 10 mL of outer membrane protein broth subcutaneously and orally respectively. Group 2 buffaloes showed typical haemorrhagic septicaemia clinical signs and were only able to survive for 72 h of the experiment. However, Group 3 buffaloes were able to survive throughout the stipulated time of 21 days of experiment. There were significant differences (p < 0.05) in the rectal temperature between the experimental and control group. In the hematology and biochemistry findings, there were significant differences (p < 0.05) in packed cell volume, mean corpuscular volume, mean corpuscular haemoglobin concentration, leukocytes, band neutrophils, segmented neutrophils, lymphocytes, eosinophils, basophils, gamma glutamyl transferase, total protein, and globulin between Group 2 and control group. In contrast, Group 3 and control group revealed significant differences (p < 0.05) in erythrocytes, haemoglobin, mean corpuscular haemoglobin concentration, segmented neutrophils, lymphocytes, monocytes, eosinophils, basophils, thrombocytes, gamma glutamyl transferase, total protein, globulin, and albumin:globulin ratio. In Group 2 buffaloes, there were gross lesions observed in the lung, trachea, heart, liver, spleen, kidney and submandibulae lymph nodes. In contrast, lesions were only observed in the lung, and liver of Group 3 buffaloes. There were significant differences (p < 0.05) in hemorrhage and congestion; necrosis and degeneration; and inflammatory cells infiltration between experimental groups and control group. However, there were no significant differences (p > 0.05) in edema between groups except for the lung. This study was a proof that oral route infection of Pasteurella multocida type B:2 immunogen outer membrane protein can be used to stimulate host cell.

Objective:To investigate the expression of TIP30 and its relationship with clinico-pathological characteristics in patients with extrahepatic cholangiocarcinoma (ECC).Methods:The expression of TIP30 in 78 cases of ECC tissues and 78 cases of para-cancerous tissues were detected by immunohistochemistry.Results:The positive expression rate of TIP30 was 43.59％ and 75.64％ in ECC tissues and para-cancerous tissues,respectively.Differences were statistically significant (P＜ 0.05).The expression levels of TIP30 were not correlated with age,gender,degree of differentiation and tumor size(P＞0.05),but correlated with lymph node metastasis,distant metastasis and TNM staging(P＜ 0.05).The median overall survival of 78 ECC cases was 14.8 months,and it of TIP30 positive expression cases was 20.3 months,statistically higher than 11.5 months in TIP30 negative expression cases(P＜ 0.01).Conclusion:The downregulation of TIP30 is closely correlated with the development,metastasis and prognosis of ECC.TIP30 may be used as a molecular marker to identify and predict the progression,metastasis and prognosis of ECC.

Clinico-pathology, hematology and biochemistry responses in buffaloes towards Pasteurella multocida type B: 2 immunogen lypopolysaccharide via oral and intravenous routes of infection.

Haemorrhagic septicaemia is a disease caused by Pasteurella multocida serotype B: 2 and E: 2. The organism causes acute, highly fatal septicaemic disease with high morbidity and mortality in cattle and more susceptible in buffaloes. Lipopolysaccharide can be found on the outer cell wall of the organism. Lipopolysaccharide is released during multiplication which leads to inflammatory reaction. It represents the endotoxin of P. multocida type B: 2 and responsible for toxicity in haemorrhagic septicaemia which plays an important role in the pathogenesis of the disease. Therefore, the aim of this study was to investigate the clinical signs, blood parameters, gross post mortem lesions and histopathology changes caused by P. multocida type B:2 immunogen lipopolysaccharide infections initiated through intravenous and oral routes of infection. 9 buffalo heifers were divided equally into 3 treatment groups. Group 1 was inoculated orally with 10 ml of phosphate buffer saline (PBS); Group 2 and 3 were inoculated with 10 ml of lipopolysaccharide broth intravenously and orally respectively. For the clinical signs, there were significant differences (p < 0.05) in temperature between the control, intravenous and oral group. In hematology and biochemistry findings, there were significant differences (p < 0.05) in erythrocytes, haemoglobin, PCV, MCV, lymphocytes, monocytes, eosinophils, GGT and albumin between the control, intravenous and oral group. However, there were no significant differences (p > 0.05) in the MCHC, leukocytes, band neutrophils, basophils, thrombocytes, plasma protein, icterus index, total protein, globulin and A:G ratio between intravenous and oral group. For Group 2 buffaloes, there were gross lesions in the lung, trachea, heart, liver, spleen, and kidney. In contrast, lesions were only observed in the lung, trachea and liver of Group 3 buffaloes. There were significant differences (p < 0.05) in hemorrhage and congestion; necrosis and degeneration; and inflammatory cells infiltration between experimental groups and control group. However, there were no significant differences (p > 0.05) in edema lesion between groups. In conclusion, this study is a proof that oral route infection of P. multocida type B:2 immunogen lipopolysaccharide can be used to stimulate host cell responses where oral vaccine through feed could be developed in the near future.

Clinico-pathology, hematology, and biochemistry responses toward Pasteurella multocida Type B: 2 via oral and subcutaneous route of infections.

BACKGROUND: Pasteurella multocida a Gram-negative bacterium has been identified as the causative agent of many economically important diseases in a wide range of hosts. Hemorrhagic septicemia is a disease caused by P. multocida serotype B:2 and E:2. The organism causes acute, a highly fatal septicemic disease with high morbidity and mortality in cattle and more susceptible in buffaloes. Therefore, the aim of this study was to investigate the clinical signs, blood parameters, post mortem and histopathology changes caused by P. multocida Type B:2 infections initiated through the oral and subcutaneous routes. METHODS: Nine buffalo heifers were divided equally into 3 treatment groups. Group 1 was inoculated orally with 10 ml of phosphate buffer saline; Groups 2 and 3 were inoculated with 10 ml of 10(12) colony forming unit of P. multocida Type B:2 subcutaneously and orally respectively. RESULTS: There was a significant difference (p<0.05) in temperature between the subcutaneous and the control group. The results revealed significant differences (p<0.05) in erythrocytes, hemoglobin, packed cell volume, leukocytes, monocytes, and A: G ratio between the subcutaneous and the control group. Furthermore, there were significant differences (p<0.05) in leukocytes, band neutrophils, segmented neutrophils, lymphocytes, eosinophils, basophils, thrombocytes, plasma protein, icterus index, gamma glutamyl tranferase and A: G ratio between the oral and the control group. The post mortem lesions of the subcutaneous group buffaloes showed generalized hyperemia, congestion and hemorrhage of the immune organs, gastro-intestinal tract organs and vital organs. The oral group buffaloes showed mild lesions in the lung and liver. Histologically, there were significant differences (p<0.05) in hemorrhage and congestion; necrosis and degeneration; inflammatory cells infiltration; and edema in between the groups. CONCLUSION: This study was a proof that oral route infection of P. multocida Type B:2 can be used to stimulate host cell responses where oral vaccine through feed can be developed in the near future.

Clinicopathological studies of gastrointestinal tract disorders in sheep with parasitic infection.

AIM: This study was envisaged to elucidate the parasitological aspects of gastrointestinal tract (GIT) disorders of sheep. MATERIALS AND METHODS: Fecal, blood and serum samples collected from 31 sheep/lambs of Sheep Breeding Farm, Lala Lajpat Rai University of Veterinary & Animal Sciences, Hisar. RESULTS: Of 25 cases, strongyle eggs (12 cases, 48%) were a major infection, followed by Strongyloides spp. (8 cases, 32%) and Moniezia spp. (5 case, 20%). In one case, massive infection of strongyle particularly Haemonchus contortus and Moniezia spp. was observed. All these animals were found negative for hemoprotozoan parasites in blood smear examination. Hematological studies revealed that significantly decreased values of hemoglobin (Hb), packed cell volume (PCV) and total erythrocytic count (TEC). Absolute leukocytic count revealed significant leukocytosis due to neutrophilia, lymphocytosis, monocytosis and eosinophilia. Serum biochemical profiles of diarrheic sheep/lambs in present study were significant decrease in values of total protein, serum globulin, glucose where as significant increase in the albumin: Globulin ratio, aspartate aminotransaminase (AST), alanine aminotransaminase (ALT), alkaline phosphatise (ALKP) and bilirubin. CONCLUSIONS: From the present study, it is reasonable to conclude that major parasitic infection of sheep/lamb observed was strongyle, followed by Strongyloides spp. and Moniezia spp. Hemato-biochemical studies revealed significant leukocytosis and increase in AST, ALT, ALKP and bilirubin.

Trichofolliculoma in Korean Patients: A report of six cases

Trichogenic tumors are a very rare group of primary cutaneous neoplasms and a few tumors have been recognized. Trichofolliculoma is a benign, papular, organoid adnexal tumor of the skin and presents as a solitary skin-colored nodule. We report six cases of trichofolliculoma occurred in Korean patients consisting of three male and three female patients. The duration of disease was variable from 3 months to 5 years. The site of tumor was limited to the face and included eyelid in two cases, nose in two cases, cheek and posterior aspect of ear in each one case. The size of the mass varied from 4 to 8 mm in diameter. Microscopically, all the cases showed large central cystic hair follicle with numerous secondary follicular buds, producing a radiating pattern. The stroma was fibrotic and well demarcated from the adjacent dermis.
