The physiological removal of foreign bodies in the horse’s external ear canal is best achieved by head-shaking. However, external otitis in the horse induces moderate to severe pain: therefore, the horse does not shake his head. The causes of external otitis are dust, water in the external ear canal, keratin, and ceruminous debris. The clinical symptoms are ear discharge, skittishness, facial nerve paresis, and/or head tilt. After the horse has been sedated, the most important diagnostic procedure is the endoscopy of the cartilaginous and osseous part of the external ear canal, including the evaluation of the transparency of the tympanic membrane. The clinical complications of external otitis are hearing loss, facial nerve paresis, head tilt, hypertrophy of the tympanostylohyoideum, and corneal ulcers. The most important treatment is soaking up the exudate in the osseous part of the external ear canal using small cotton balls which are held by the foreign body forceps of the endoscope. Based on the results of the culture of exudate and the antibiogram, an antibacterial drug must be administered orally for 3 to 4 weeks. At this time, an endoscopy of the external ear canals and guttural pouches also has to be done. Based on the outcome of the endoscopy, endoscopic and clinical investigations have to be performed six months later as well. Only 7/19 horses had a normal osseous part of the external ear canal with a transparent tympanic membrane, including normal hearing measured by the brainstem auditory-evoked response after one month of treatment.

The N-hydroxydodecanamide (HA12) and its complexes tri-hydroxamato-iron(III) and di-hydroxamto-iron(III) chloride (HA8Fe3 and HA12Fe3Cl, respectively) showed antibacterial and antimycobacterial activities. The proteomic analysis demonstrated that the targets of Hydroxamic Acid (HA) and their complexes were involved in the biosynthesis of mycobacterial cell walls. The Reactive Oxygen Species (ROS) is one of the key elements to cause oxidative stress, damaging DNA, and cell membranes impaired during the procedure to kill bacteria. Here, the ROS production was determined to evaluate the compounds HA12, HA8Fe3, HA12Fe3Cl, and ZnCl2 against bacteria using 2’,7’-dichlorofluorescein diacetate (DCFDA) by spectrofluorometric analysis. The low fluorescence was observed using the compounds HA12, HA8Fe3, HA12Fe3Cl, and ZnCl2 treating the S. aureus and E. coli, indicating that the ROS production could not be observed using the compounds used at a dose higher than the Minimum Inhibitory Concentration (MIC). It was noted that the ROS determination could be performed with a concentration less than or equal to the MIC. This would enable the mechanism of action linked to the ROS production by HA and their metal complexes to be determined.

A 51-year-old female with a history of multinodular goitre presented with vomiting, abdominal discomfort, and generalized tiredness. Investigations revealed hypercalcemia (ionized calcium 1.41 mmol/L), hypokalaemia, suppressed parathyroid hormone, and significantly elevated free thyroxine (> 7.77 ng/dL) with a suppressed thyroid-stimulating hormone level consistent with hyperthyroidism. Further, the workup confirmed Graves’ disease as the underlying aetiology. Hyperthyroidism is occasionally associated with mild to moderate hypercalcemia, but severe hypercalcemia or hypercalcaemic crisis is an extremely rare complication. Prompt recognition and treatment are crucial to prevent life-threatening complications. The patient was treated with intravenous fluids, a low-calcium diet, zoledronic acid, carbimazole, and a beta-blocker, leading to improvement in her condition. This case highlights a rare occurrence of hypercalcaemic crisis in a patient with thyrotoxicosis due to Graves’ disease. Hyperthyroidism-induced hypercalcemia requires prompt recognition and multidisciplinary management involving endocrinologists, internists, and critical care specialists to prevent potentially life-threatening complications. Healthcare providers should consider the hypercalcaemic crisis in the differential diagnosis of hypercalcemia in the context of hyperthyroidism.

This study investigates into the historical evolution and contemporary applications of Computed Tomography (CT) in renal stone estimation, with a focus on the innovative use of CT to quantify renallcalculiistrain for estimating potentiallsymptomatic incidents.Historically, CT has played a pivotal role in diagnosing renal calculi, offering unparalleled sensitivity and specificity in detecting stones of varying composition and size. However, the clinical significance of renal calculi extends beyond mere detection, prompting researchers to explore novel approaches to predict symptomatic events associated with stone disease. This research aimed to determine the right way to classify asymptomatic radiographic calculi strain on computed tomography (CT) scans in Al-Hussein Teaching Hospital, Al-Muthanna, Iraq. A survey was made available to calculi formers who had a CT scan during asymptomatic after a calculi clinical assessment. A survey and a study of medical records revealed symptomatic calculi route incidents after a CT scan. The amount of calculus, the biggest calculi thickness, electronic total calculi size (TSV), and two-pronged calculus were measured radiographically and linked as predictors of calculi events. There were 55 calculi formers in the study, and 61% had a calculi event one year after the CT scan. The calculus number was (0–1, 2–3, 4–6, 7), the highest calculi diameter was (0–2, 3–4, 5–7, 8 mm), and 48% had bilateral calculus. The number of calculus per quartile had a danger ratio of 1.30 (p = 0.001), the largest calculi diameter had a hazard ratio of 1.26 (p  0.001), TSV had a hazard ratio of 1.38 (p = 0.001), and bilateral calculus had a hazard ratio of 1.80 (p = 0.001). Only TSV wass an unbiased measure offsymptomaticceventssin multivariable regression (HR = 1.35 per quartile, p = 0.01). TSV-related incidents were also unaffected by demographics, urinary chemistry, or calculi composition. A drastic rise in TSV between CT scans (> 31 mm3/year) expected additional eventssin the 49 patients with interim events (HR = 2.8, p = 0.05). For calculating calculi pressure on CT scan, automated TSV is more accurate for asymptomatic events than physical approaches.

Juvenile Xanthogranulomatosis (JXG) is a condition, characterized by a proliferation of histiocytes, primarily observed in infants and young children. Cutaneous manifestations appear as yellow-orange-brown papules or nodules, typically localized on the face, neck, and upper chest. While most lesions regress spontaneously, some may require intervention for aesthetic, diagnostic, or hemorrhagic reasons. A rare case of disseminated JXG in a child with hemophilia has been reported. In this patient with severe hemophilia A, cutaneous nodules appeared, some associated with bleeding requiring appropriate management. Treatment included the administration of factor VIII to prevent bleeding during surgical procedures and secondary prophylaxis, to control recurrent bleeding. The outcome was favorable with the disappearance of the cutaneous lesions without sequelae, under regular surveillance for both medical conditions. This case highlights the rare association between juvenile xanthogranulomatosis (JXG) and hemophilia, a combination that has never been documented in the medical literature. This association only impacts the management of JXG when the cutaneous lesions bleed and their excision becomes necessary.

Background: The unwanted adverse toxicity displayed by synthetic antidiabetic medicine leads to the search for effective natural medicine to combat diabetes complications. This study investigated the cardioprotective of Anacardium occidentale nuts methanolic in high-fat diet (HFD)/streptozotocin (STZ)-induced diabetic rats.Materials and methods: Forty male adult Wistar were used and fed with HFD for 6 weeks before diabetes induction. The rats were grouped into 5 groups, 8 rats/group. Group I: normal control; Group II: diabetic control; Group III & IV: diabetic rats + 100 mg/kgb.wt & 200 mg/kgb.wt Anacardium occidentale nuts methanolic extract; Group V: diabetic rats + 200 mg/kgb.wt metformin. The rats were sacrificed on the experiment’s last day, blood samples were collected and the hearts were isolated for biochemical parameters estimation.Results: Food intake, water intake, plasmas insulin, Fasting Blood Glucose (FBG), glycosylated hemoglobin (HbA1c), cardiac enzymes, lipid profile, inflammatory cytokines, malondialdehyde, fibrotic marker, caspase-3 in cardiac of diabetic rats were elevated (p < 0.05) significantly. Body weight, cardiac antioxidant, and anti-apoptotic marker levels diminished (p < 0.05) significantly in diabetic rats. 100 mg/kgb.wt & 200 mg/kgb.wt of Anacardium occidentale nuts methanolic extract administration significantly suppressed the plasma insulin, FBG, HbA1c, cardiac lipid profile, cardiac enzymes biomarker, cardiac inflammatory cytokines, cardiac malondialdehyde, cardiac fibrotic marker, cardiac caspase-3, food intake & water intake and increased the body weight, cardiac antioxidant & cardiac anti-apoptotic marker in the diabetic rats.Conclusion: Anacardium occidentale nuts attenuate cardiac injury in diabetes. It could be a natural medicine to manage diabetes-cardiovascular complications.

This study compares the effect of imipramine and amitriptyline on learning and memory. Thirty-five (35) healthy Swiss white (CD1) mice of both sexes weighing 18 g - 30 g were randomly divided into 5 groups (n = 7). Mice in group 1 (control) were administered 0.9% normal saline orally, while mice in groups 2 and 3 were treated with low (1.8 mg/kg) and high (3.7 mg/kg) doses of imipramine, groups 4 and 5 were treated with low (1.8 mg/kg) and high (3.7 mg/kg) of amitriptyline respectively. Treatment was for 21 days before tests. All animals were tested using the Morris Water Maze (MWM) and Novel Object Recognition Task (NORT) to assess visuospatial learning and memory as well as cognitive learning and memory. The results obtained from the Morris Water Maze during the acquisition training showed that the swim latencies were significantly lower (p < 0.05) in the amitriptyline low-dose group compared to the control group. During the reversal training, the swim latencies were significantly lower (p < 0.05) in the test groups compared to the control group. The result for the retention quadrant in the probe trials showed a significant decrease (p < 0.05) in the northeast quadrant in the test groups compared to the control group, with no significant difference in the visible platform day of the Morris Water Maze in the test groups compared to the control group. In the novel object recognition task, the short-term index of habituation was significantly lower (p < 0.05) in the low-dose imipramine and low-dose amitriptyline compared to the control group, the results also showed a significant increase (p < 0.05) in amitriptyline high dose group compared to imipramine and amitriptyline low dose group and the control group. The index of discrimination showed no significant difference among all groups. The long-term index of habituation and discrimination in the memory test showed a significant decrease (p < 0.05) in all the test groups compared to the control group. The results suggest that imipramine and amitriptyline impaired cognitive memory and enhanced visuospatial learning and memory functions.

Aim: This study examines the pathological outcomes of chronic liver injuries, with a focus on liver fibrosis. It emphasizes understanding the structural changes within the liver that may lead to cirrhosis and functional impairments, crucial for developing targeted antifibrotic therapies.Methods: Our approach reviews existing literature detailing the use of traditional diagnostic methods—biochemical and serological tests alongside liver biopsies. Additionally, we evaluate the reliability and efficacy of non-invasive techniques such as serological test panels and imaging examinations. These methods are compared to understand their viability as supplementary or alternative diagnostic tools to liver biopsy.Significance: Liver fibrosis, if unmanaged, can progress to severe conditions such as cirrhosis and hepatocellular carcinoma, making it vital to understand its progression and treatment options. This study underscores the need for precise and non-invasive diagnostic tools in the clinical management of liver fibrosis, providing insight into the progression of chronic liver diseases and potential therapeutic targets.Conclusion and future perspectives: The research confirms that while liver biopsy remains the definitive method for staging liver fibrosis, its risks and limitations necessitate the use of enhanced non-invasive diagnostic techniques. These methods have shown promising results in accuracy and are critical for broadening clinical applications and patient safety.It is recommended that the scientific community continue to develop and validate non-invasive diagnostic tools. Enhancing the accuracy and reliability of these tools can provide a cost-effective, accessible, and safer alternative for large-scale screening and management of liver fibrosis in asymptomatic populations. Additionally, integrating advancements in radiologic and serological markers can further refine these diagnostic methods, improving overall patient outcomes.

Rheumatic heart disease persists as a significant concern in developing regions, often resulting in multivalvular heart conditions. Treatment options are limited, though percutaneous transvenous mitral commissurotomy effectively addresses rheumatic mitral stenosis. Non-surgical interventions for aortic stenosis include balloon aortic valvotomy and Transcatheter aortic valve replacement (TAVR), tailored to patient factors like age and comorbidities.We describe two cases of Rheumatic multivalvular disease which were managed non-surgical. The first case is a pioneering procedure performed on a young patient combined percutaneous transvenous mitral commissurotomy with balloon aortic valvotomy, guided by 4-dimensional transoesophageal echocardiography (4D TEE). This represents the first documented instance in medical literature, showcasing the potential of integrated interventions and advanced imaging techniques. In the second challenging case involving a heavily calcified, retrovirus, and Hepatitis B positive 55-year-old, a staged approach was adopted, involving percutaneous transvenous mitral commissurotomy followed by Transcatheter aortic valve replacement (TAVR). Despite complexities, this sequential strategy demonstrates the adaptability of transcatheter techniques in managing complex valvular pathologies. These cases highlight the evolving landscape of interventional cardiology and underscore the importance of tailored, multidisciplinary approaches in optimizing outcomes for patients with rheumatic heart disease and multivalvular involvement, especially in resource-limited settings. Further exploration and dissemination of such innovative strategies hold promise for enhancing cardiac care quality and expanding treatment options globally.

Immune Checkpoint Inhibitors (PCIs,) are monoclonal antibodies directed against immune checkpoint regulatory molecules. These antibodies inhibit T-cell activation and prolong survival in patients with different types of cancer. However, they can produce adverse effects related to the immune response such as renal damage.We present the clinical case of a 75-year-old man with a personal history of Chronic Kidney Disease (CKD) and metastatic renal cancer with lung, bone, and mediastinal involvement. He started treatment with immunotherapy with Nivolumab-Ipilimumab. Then, after 4 cycles of immunotherapy, the patient was admitted to the Urology Department for an adverse reaction to immunotherapy with the development of nephritis and toxic hepatitis. Despite treatment with methylprednisolone, he evolved poorly, and a palliative approach was finally decided.The incidence of acute renal failure attributed to PCIs is estimated at 2% - 3%, being grade I-II in most cases. Among the renal complications associated with PCIs, acute interstitial nephritis is the most predominant with an incidence of 80% - 90% of cases. In addition, an increased risk is observed in patients with intermediate or poor risk metastatic renal cancer.Despite their fundamental role in metastatic renal cancer, we must take into account the potential for renal failure as an adverse effect of PCIs, especially in patients with previous CKD.
