Anterior provisional fixed partial dentures: A finite element analysis.

PURPOSE: The aim of this study was to analyze the stress distribution of fiber-reinforced composite provisional fixed partial denture utilizing a finite element analysis model. MATERIAL AND METHODS: Three anterior teeth were collected: upper right central, left central, and right lateral incisors. A fiber-reinforced composite strip was applied to the palatal surfaces of the teeth. Micro-computed tomographic scans were acquired of the models in order to generate three-dimensional geometrical replicas. Finite element analysis was used to assess the stress distribution of fiber-reinforced composite provisional fixed partial denture using different pontic types under static applied forces that were 100, 30, and 0 N. RESULTS: The maximum stress values were found on the unprepared natural pontic. Stress values ranged from 92.2 to 909.8, 116.4 to 646.7, and 93.8 to 393.5 MPa for composite, naturally prepared, and natural unprepared pontic, respectively. CONCLUSIONS: Using unprepared natural tooth pontic in anterior provisional fixed partial denture to replace missing central incisors is considered superior to other types in terms of stress distribution.

Comparison of the Outcomes of Oral Versus Nasal Endotracheal Intubation in Neonates and Infants Undergoing Cardiac Surgery: A Randomized Controlled Study.

OBJECTIVE: The choice of oral or nasal endotracheal intubation in children undergoing cardiac surgery is affected by several factors. This study compared the outcomes of oral versus nasal intubation in neonates and infants who underwent open cardiac surgery. DESIGN: A randomized, controlled, open-labeled study. SETTING: At a university hospital. PARTICIPANTS: A total of 220 infants and neonates who underwent cardiac surgery. INTERVENTIONS: Patients were allocated randomly to oral or nasal intubation. MEASUREMENTS AND MAIN RESULTS: The primary outcome measure was postoperative fentanyl consumption (µg/kg/h) by intubated patients. Secondary outcome measures were the increase in heart rate (HR) from baseline during intubation, the time consumed for intubation, accidental intraoperative extubation, the occurrence of epistaxis, time to extubation, the onset of full oral feeding, intensive care unit (ICU) and hospital lengths of stay, and the incidence of postoperative complications (the need for reintubation, stridor, pneumonia, wound infection). The mean (SD) postoperative fentanyl consumption of intubated patients (the primary outcome) was significantly lower (p < 0.001) in the nasal intubation group (0.53 ± 0.48) µg/kg/h compared with the oral intubation group (0.82 ± 0.20) µg/kg/h. The median (IQR) time needed for the intubation (31.5, 27-35 v 16, 14.8-18 seconds) was significantly (p < 0.001) longer, and the mean (SD) increase in HR (beats/min) from baseline during intubation (18 ± 5 v 26 ± 7) was significantly (p < 0.001) lower in the nasal intubation group compared to the oral intubation group. The incidence of inadvertent intraoperative extubation was significantly (p = 0.029) higher in the oral (n = 6, 6.1%) than in the nasal (n = 0, 0%) intubation group. The median (IQR) time to extubation (14, 12.6-17.2 v 20.5, 16.4-25.4 hours) and the ICU length of stay (27, 26-28 v 30, 28-34 hours) were significantly (p < 0.05) shorter in the nasal group compared to the oral group. The median (IQR) time to onset of full oral feeding was significantly (p = 0.031) shorter in the nasal intubation group (3, 1-6 days) compared to the oral intubation group (4, 2-7 days). There were no significant differences between the oral and nasal groups in the duration of hospital stay and the indices for reintubation, postintubation stridor, pneumonia, and surgical wound infection. CONCLUSIONS: The nasal route for intubation is associated with less postoperative fentanyl consumption, earlier extubation, lower incidence of accidental extubation, and earlier full oral feeding than oral intubation. The nasal route is not associated with an increased risk of postoperative pneumonia or surgical wound infection.

The Expression of Stem Cell Marker LGR5 and Its Coexpression with Β-Catenin in Sporadic Colorectal Carcinoma and Adenoma: A Comparative Immunohistochemical Study.

Background: LGR5 is one of the most important stem cell markers for colorectal cancer (CRC), as it potentiates Wnt/Β-catenin signaling. The well-characterized deregulation of Wnt/Β-catenin signaling that occurs during adenoma/carcinoma sequence in CRC renders LGR5 a hopeful therapeutic target. We assessed the immunohistochemical expression of LGR5 and Β-catenin in normal colonic and tumorous lesions with a clinicopathological correlation. Methods: Tissue blocks and clinical data of 50 selected cases were included: 8 from normal mucosa, 12 cases of adenoma, and 30 cases of CRC, where sections were cut and re-examined and the immunohistochemical technique was conducted using anti-LGR5 and anti-Β-catenin to measure the staining density. Results: There was no expression of LGR5 in normal mucosa compared to samples of adenoma and CRC samples. The association analysis showed that CRC specimens were more likely to have strong LGR5 and Β-catenin expressions than the other two groups (p = 0.048 and p < 0.001, respectively). Specimens with high-grade dysplastic adenoma were more likely to express moderate-to-strong expression of LGR5 and Β-catenin (p = 0.013 and p = 0.036, respectively). In contrast, there were no statistically significant associations between LGR5 and Β-catenin expression with grade and stage. Conclusion: These results suggest and support the possible role of LGR5 as a potential marker of cancer stem cells in sporadic colorectal carcinogenesis in addition to a prognostic value for LGR5 and Β-catenin in adenomatous lesions according to immunohistochemical expression density. A potential therapeutic role of LGR5 in CRC is suggested for future studies based on its role in pathogenesis.

Ultrasound detection of cosmic filler injection of lips in camel beauty pageants: first report in veterinary medicine.

This study was carried out in Saudi Arabia during the events of the 4th King Abdulaziz Camel Festival, Saudi Arabia. It was designed to describe the most frequent locations of injected cosmetic fillers in the head region as well as the ultrasound features of the injected material. Apparently healthy camels (Camelus dromedarius) (n = 11,626) were thoroughly examined for injection of cosmetic fillers in the head region. In parallel, 30 non-injected camels were used as controls. The lips of camels suspected of having been injected with fillers were subjected to high-resolution ultrasound examination. Of the 11,626 camels, 58 were found to have been injected with cosmetic fillers, 45 in the upper lip and 13 in both the upper and lower lip. None of the injected camels had a history of recent illness. In addition, in all the injected camels, no dermal lip lesions were seen by the naked eye. Swelling of the upper and/or lower lips was visually inspected and palpated by hand in 52 of the camels. Drooping and swinging of the injected lips were observed in all injected camels. Hardness was detected in the tip of the upper lips of 26 of the injected camels and multiple hard nodules were palpated in the injected lips of 44 camels. Swelling of the edges of the upper and lower lips was detected in 41 of the injected camels. Ultrasonographic features of the injected lips are described in detail. Blood samples were collected from both groups. In none of the injected camels did the hemato-biochemical profiles differ significantly than the control group. In conclusion, results clearly indicate the usefulness and convenience of ultrasound as a diagnostic tool to locate the presence of injected fillers and to help monitor the extension and complications of the deposits.

Scrotal enlargement in rams and bucks in Qassim region, central of Saudi Arabia: clinical and ultrasonographic findings and seroprevalence of brucellosis.

The aim of this study was to clarify the causes of scrotal enlargement in rams and bucks in Qassim region of Saudi Arabia. Enlarged scrotal contents of rams and bucks (n = 153) were examined by visual inspection, palpation, and ultrasonography. Blood samples were obtained and tested for Brucella sp. infection. Clinical and ultrasonographic findings showed that scrotal enlargement was mainly associated with orchitis, peri-orchitis, and epididymitis. Miscellaneous findings were scrotal hernia, scrotal hematoma, and hydrocele. The frequencies of orchitis, peri-orchitis, and epididymitis were 47.4, 21.1, and 14.1% in Awassi rams; 54.5, 21.7, and 8.7% in Najdi rams; 52.3, 20.5, and 9.1% in Ardi bucks; and 50, 16.7, and 16.7% in Damascus bucks, respectively. Orchitis was associated with no-abscess formation (23%), single-abscess formation (15.4%), and multiple-abscesses formation (61.6%). Peri-orchitis was characterized by hard consistency, atrophy of the testes, and extensive connective tissue formation. Epididymitis was observed mainly at the tail of the epididymis (82.4%) but rarely at the head (17.6%). Epididymitis was associated in many cases with abscessation (70.6%). Males with orchitis, peri-orchitis, and epididymitis were positive for Brucella melitensis and Brucella ovis in the frequency of 21.3% and 48.8%, respectively. In conclusion, scrotal enlargement in rams and bucks in Qassim region is caused mainly by inflammation of the testis and/or epididymis and associated tremendously with brucellosis seropositivity.

A randomized controlled trial evaluating sildenafil citrate in relieving ureteral stent-related symptoms.

PURPOSE: To evaluate the role of sildenafil in relieving ureteral stent symptoms. PATIENTS AND METHODS: A randomized controlled trial was conducted between March 2014 and November 2016. It included adult men who underwent unilateral ureteric stent after ureteroscopy. Patients who were taking PDE5-Is, alpha-blockers or anticholinergics, had contraindication to sildenafil or developed postoperative complications were not included. Eligible patients were randomized using sealed closed envelops to one of two groups (S and C). Patients in group S received sildenafil citrate 50 mg tablet once daily. Patients in group C were the control. All patients answered the ureteral stent symptom questionnaire (USSQ) after 2 weeks of stenting. Primary outcome was the difference in total USSQ score between both groups. Secondary outcomes were tolerability of the treatment and the difference in each domain of USSQ score. RESULTS: After randomization, four patients (7.3%) in group C withdraw their consent because of severe symptoms and two patients (3.6%) in group S discontinued treatment because of headache and dizziness. Final analysis was performed for 46 and 48 patients in groups C and S, respectively. Total USSQ score and all domains (except work performance) were significantly lower in group S (P < 0.001). Dysuria and urgency were significantly more in group C (P = 0.012 and 0.007, respectively). Three patients in groups S (6.25%) experienced transient mild adverse effects (dyspepsia, flushing and rhinitis in one patient for each) but they continued sildenafil. CONCLUSIONS: Sildenafil is an effective and well-tolerated treatment option for relieving ureteral stent-related symptoms in men. CLINICALTRIAL. GOV IDENTIFIER: NCT02345980.

Ultrasonographic findings in goats with contagious caprine pleuropneumonia caused by Mycoplasma capricolum subsp. capripneumoniae.

BACKGROUND: In goats, contagious caprine pleuropneumonia (CCPP) is a cause of major economic losses in Africa, Asia and in the Middle East. There is no information emphasising the importance of diagnostic ultrasound in goats with CCPP caused by Mycoplasma capricolum subsp. capripneumoniae (Mccp). This study was designed to describe the ultrasonographic findings in goats with CCPP caused by Mccp and to correlate ultrasonographic with post-mortem findings. To this end, 55 goats with CCPP were examined. Twenty-five healthy adult goats were used as a control group. RESULTS: Major clinical findings included harried, painful respiration, dyspnoea and mouth breathing. On ultrasonography, a liver-like echotexture was imaged in 13 goats. Upon post-mortem examination, all 13 goats exhibited unilateral pulmonary consolidation. Seven goats had a unilateral hypoechoic pleural effusion. At necropsy, the related lung was consolidated and the pleural fluid appeared turbid and greenish. Pleural abscessiation detected in five goats was confirmed post-mortem. Twenty-eight goats had a bright, fibrinous matrix extending over the chest wall containing numerous anechoic fluid pockets with medial displacement and compression of lung tissue. Echogenic tags imaged floating in the fluid were found upon post-mortem examination to be fibrin. In two goats, a consolidated right parenchyma was imaged together with hypoechoic pericardial effusions with echogenic tags covering the epicardium. At necropsy, the right lung was consolidated in three goats and fibrin threads were found covering the epicardium and pericardium. CONCLUSIONS: In goats with CCPP, the extension and the severity of the pulmonary changes could not be verified with clinical certainty in most cases, whereas this was possible most of the time with sonography, thus making the prognosis easier. Ultrasonographic examination of the pleurae and the lungs helped in the detection of various lesions.

A randomized controlled trial comparing alpha blocker (tamsulosin) and anticholinergic (solifenacin) in treatment of ureteral stent-related symptoms.

PURPOSE: To compare the effectiveness of tamsulosin and solifenacin in relieving ureteral stents related symptoms. PATIENTS AND METHODS: A randomized controlled trial was conducted between January 2013 and July 2014. Inclusion criteria were patients aged 20-50 years who underwent temporary unilateral ureteral stent for drainage of calcular upper tract obstruction or after ureteroscopic lithotripsy. Patients with history of lower urinary tract symptoms before stent placement, stents that were fixed after open or laparoscopic procedures, and those who developed complications related to the primary procedure were not included. Eligible patients were randomly assigned to 1 of 3 groups using computer-generated random tables. Patients in group 1 received placebo, patients in group 2 received tamsulosin 0.4 mg once daily, and those in group 3 received solifenacin 5 mg once daily. Ureteral Stent Symptom Questionnaire (USSQ) was answered by all patients 1-2 weeks after stent placement. The primary outcome was the comparison of total score of USSQ between all groups. RESULTS: The study included 131 patients. All baseline characteristics (age, sex, side, indication, length, and duration of stent) were comparable for all groups. Total USSQ score was 61 in solifenacin group, 76 in tamsulosin group, and 83 in control group (P < 0.001). The total USSQ scores and all domains, except sexual index, were significantly better in solifenacin than in tamsulosin group (P < 0.05). CONCLUSION: The use of tamsulosin alone or solifenacin alone in patients with ureteral stents can improve the quality of life by decreasing ureteral stent-related symptoms. Solifenacin was better than tamsulosin. CLINICALTRIAL. GOV IDENTIFIER: NCT01880619.

Influence of the cardiac glycoside digoxin on cardiac troponin I, acid-base and electrolyte balance, and haematobiochemical profiles in healthy donkeys (Equus asinus).

BACKGROUND: The effect of digoxin administration on the serum concentration of the cardiac troponin I (cTnI) has not been reported to date in equidae. This study was therefore designed to evaluate the effect of digoxin on cardiac cell damage in donkeys (Equus asinus) as assessed by cTnI, acid-base and electrolyte balance and haematobiochemical profiles. Ten clinically healthy donkeys were given an IV infusion of digoxin at a dose of 14 µg/kg. Blood samples were collected from the donkeys up through 72 h post-injection. RESULTS: Three of the donkeys exhibited increased heart and respiratory rates post-injection. In the other seven animals, the heart and respiratory rates were lower 4 h post-injection. The serum digoxin concentration increased significantly at many time points after injection. The serum concentration of cTnI did not differ significantly between pre- and post-injection. An increase in blood pH was noted at 3 h after digoxin injection. There were also increases in PO2 and in oxygen saturation. Decreases in PCO2 at 2 to 48 h post-injection as well as a decrease in blood lactate at 4 h post-injection were observed. The serum concentration of glucose remained significantly elevated at all-time points after digoxin injection. CONCLUSIONS: It is concluded that administration of digoxin to healthy donkeys (14 µg/kg) did not result in elevations of serum cTnI concentration, signs of digoxin intoxication, ECG abnormalities and did not increase serum concentrations of blood urea nitrogen and creatinine.

The effect of tick infestation on the serum concentrations of the cardiac biomarker troponin I, acid-base balance and haematobiochemical profiles in camels (Camelus dromedarius).

The aim of the present study was to evaluate the serum concentration of cardiac troponin I (cTnI) in camels with tick infestation as a marker of potential myocardial injury and its prognostication. The effects of acid-base and electrolyte balance and haematobiochemical profiles were also investigated. Twenty-three camels (Camelus dromedarius) with tick infestation and suffering from anorexia, incoordination of movement, unsteady gait, recumbency, opisthotonus, anaemia and reduced production were examined. Ticks were visible, deeply embedded in the skin over the whole body, especially under the neck and around the udder or testis. Of the camels, 15 recovered after treatment and 8 did not. Blood samples were collected from the diseased camels on the day of admission to our clinic. Blood samples were also collected from 12 healthy camels and were used as controls. The mean serum concentration of cTnI in the camels with tick infestation was 1.7 ± 1.6 ng/ml compared to 0.03 ± 0.02 ng/ml in the controls. The mean serum concentration of cTnI in those camels that recovered was 0.36 ± 0.53 ng/ml compared to 3.0 ± 1.1 ng/ml in the camels that did not. Venous blood gas alterations included an increase in partial pressure of carbon dioxide and decreases in partial pressure of oxygen and oxygen saturation. Haematological parameters involved decreases of red blood cells, haemoglobin and haematocrit and increases in the mean corpuscular volume, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration. Biochemical parameters included significant elevations in the serum activity of aspartate aminotransferase, creatine kinase and alkaline phosphates. Other biochemical alterations observed were decreases in total protein and albumin and increases in globulin and glucose concentrations. In conclusion, the data of this study suggest the possibility of using cTnI as a biomarker for cardiac injury in camels with tick infestation and for the prognosis of the outcome in the treated animals. Generally, values above 1.0 ng/ml were considered bad prognostic indicators.

Diagnostic utility of ultrasonography for thoracic and abdominal bacterial and parasitic diseases in ruminants: a comprehensive overview.

This review article describes the roles of ultrasound in assessing thoracic and abdominal infectious diseases, mainly bacterial and parasitic ones that affect farm animals, including cattle, camels, sheep, and goats. Ultrasonography is a non-invasive imaging technique used to diagnose infectious diseases affecting the cardiovascular, respiratory, digestive, urinary, and hepatobiliary systems. In cases of thoracic and abdominal infections, ultrasound typically reveals abnormalities in echogenicity and echotexture, the presence of unusual artifacts, and mass formation exerting pressure on surrounding structures. Inflammatory and degenerative changes within the viscera can be identified ultrasonographically by comparing the echogenicity of affected areas with that of the surrounding normal parenchyma, such as in fascioliasis. Bacterial and parasitic infections often result in capsular mass lesions with anechoic contents, as observed in hydatid cysts and cysticercosis, or varying echogenic contents, as observed in liver abscesses. Effusions within the pericardium, pleura, and peritoneum are common ultrasonographic findings in infectious thoracic and abdominal diseases. However, these effusions' echogenicity does not always allow for clear differentiation between transudates and exudates. The routine use of ultrasonography in the evaluation of the chest and abdomen in affected or suspected ruminants is highly beneficial for detection, guiding therapeutic decisions, assessing prognosis, and aiding in the eradication of highly contagious diseases that cause significant economic losses.

Discolored urine in sheep and goats: Clinical, etiological, hematobiochemical, sonographic and postmortem findings.

Background: Bloody urine is classified in farm animals as hematuria, hemoglobinuria, and myoglobinuria. In small ruminants, discolored urine is reported due to several etiologies which is sometimes fatal. Of these causes are babesiosis, bacillary hemoglobinuria, copper toxicity, and hypophosphatemia. Aim: This study was designed to investigate the clinical, etiological, hematobiochemical, ultrasonographic, and pathological findings in rams and bucks with red urine syndrome. Methods: Eighteen male animals (nine rams and nine bucks) of 6 months to 3 years were examined. Parallel, 10 healthy controls were used. They were admitted due to red urine, voiding of only urine drops, straining during the act of urination, grunting during urination, ventral abdominal edema, and abdominal distension. The duration of the disease ranged from 2 to 30 days. A history of chronic copper toxicosis was informed in two bucks and a ram. Two blood samples were collected from diseased as well as from controls in EDTA tubes (for complete blood count testing) and in plain tubes (for serum collection). Results: Hematuria was found in 11 animals (seven bucks and four rams) while hemoglobinuria was detected in seven animals (five bucks and two rams). Sonographic findings in diseased animals included ruptured urinary bladder in 3, ruptured urethra in 5, penile calculi, uroperitoneum in 6, distended urinary bladder in 7, hydronephrosis in 5, echogenic deposits in the bladder in 3, and ventral urine accumulation in four animals. Laboratory evaluation of a Geimsa-stained blood smear confirmed the infection with Babesia in three bucks and a ram. Hemolytic anemia was marked in two bucks and a ram due to chronic copper toxicity. Biochemical abnormalities included hypoalbuminemia, hyperglobulinemia, increased blood urea nitrogen and creatinine concentration, and hyperglycemia. Postmortem examination was carried out on six animals (four rams and two bucks). Conclusion: Discolored urine in rams and bucks in this study resulted from hematuria due to urinary calculi and pelvic abscessation or from hemoglobinuria due to Babesia infection or due to copper toxicity. Hemolytic anemia was the outstanding hematological finding and hypoalbuminemia, hyperglobulinemia, increased blood urea nitrogen (BUN) and creatinine, and hyperglycemia were the characteristic biochemical findings. Sonography of the urinary tract was very helpful in assessing the renal parenchyma, urinary bladder, and abdominal cavity for the verification of urolithiasis, hydronephrosis, intact or ruptured urinary bladder, uroperitoneum, and perforated urethra.

Effect of pomegranate peel with/without autologous bone marrow on healing of acute cutaneous wounds in alloxan-induced diabetic rabbits.

Background: Healing of bum wounds is commonly associated with many complications. Every year various new repair materials are developed and experimentally used for treating burn wounds. Humans with diabetes mellitus usually suffer from chronic wound healing. Vascular, neuropathic, immune function, and biochemical abnormalities each contribute to the altered tissue repair. One underlying factor that accompanies all diabetic ulcerations is poor vascular flow, a circumstance that impedes proper wound healing. Numerous studies have highlighted the importance of adequate vascular sufficiency and vessel proliferation in tissue repair and the lack thereof in diabetic wound healing. Other studies have looked at whether disarrayed capillary remodeling and maturation of vessels might play a role in impaired diabetic wound healing. Aim: This investigation has been planned to report the influence of treatment with a mixture of both the powder of pomegranate peel (PP) accompanied with an autologous bone marrow (BM) on the cure of burn injuries in experimentally induced diabetic rabbits. Methods: Alloxan monohydrate has been applied to create diabetes in 50 rabbits. Then in each rabbit, two deep second-degree burn wounds were experimentally created. The animals were then divided randomly into 5 treatment sections: non-treatment controls (C1), treated with an available commercial powder for wound (C2), treatment with powder of PP, treatment with alone BM, and the final group treated with PP powder with bone marrow (PPBM). The speed of wound closure and the histopathological changes during healing were measured. The levels of the biomarkers of rabbit platelet-derived growth factor AA (PDGF-AA) and rabbit protease-activated receptor 1 (PAR-1) were measured on days 0, 4, 8, and 12. Results: Wound healing was markedly more rapid in all the treatment groups versus the control non-treated group. Interestingly, a rapid wound cure was significantly observed in the PPBM group versus the other treatment ones. The histological assessment clarified a significant elevation in the fibroblast and collagen scores in the PPBM group versus the other sections. In addition, there were significant increases in the serum levels of the biomarkers PDGF-AA and PAR-1 among groups. Conclusion: Dependent on the results of current research, it can be concluded that both PP powder with BM PPBM significantly accelerate the healing process of burn wounds in experimentally induced diabetic rabbits.

Changes in the hematobiochemical, acid-base and blood gas elements as well as biomarkers of inflammation and bone metabolism in donkeys (Equus asinus) with acute bleeding.

Background: Acute hemorrhage is fatal in equines with a complication of severe hypovolemic shock that causes a sudden death in such cases. Aim: This study was designed to report the influences of acute bleeding in conscious non-sedated donkeys (Equus asinus) on the hematobiochemical variables, acid-base, blood gas elements, and markers of inflammation and bone metabolism. Methods: Eight healthy donkeys were used where a total of 900 ml of whole blood was collected. Five blood samples were collected from each animal: just before collection of blood (T0); (2) 30 (T1), 60 (T2), 120 (T3), and 240 minutes (T4) later. The blood panels including total white blood cells, lymphocytes, neutrophils, red blood cell counts (RBCs), HCT, hemoglobin (Hg), and RBCs indices were measured. Biochemical parameters and electrolytes were evaluated. The activity of aspartate aminotransferase (AST), creatine kinase (CK), and γ-glutamyl transferase (GGT) were also determined. Complete acid-base and blood gas panels were assessed. Serum amyloid A (SAA), haptoglobin (Hp), osteocalcin (OC), bone alkaline phosphatase (b-ALP), and pyridinoline cross-links (PYD) were measured. Results: The RBCs, Hg, and HCT increased significantly at points T1, T2, and T3 compared to T0. The concentrations of total proteins and albumin decreased significantly at points T3 and T4. The blood urea nitrogen concentrations increased significantly at T4. Creatinine concentrations increased significantly at T2 and T3. The AST, GGT, and CK decreased significantly. On the other hand, glucose increased significantly at T3 and T4. The pH decreased significantly at points T1, T2, T3, and T4. The PCO2 increased significantly at T3 and T4. The BE, HCO3, and TCO2 values decreased significantly at T2, T3, and T4. Contrary, the AG increased significantly at points T3 and T4. The potassium increased significantly at T1-T4 and chloride decreased significantly at T3 and T4. Lactate showed significant increases at T1-T4. The SAA, Hp, OC, b-ALP, and PYD did not differ significantly at T1-T4. Conclusion: In conscious non-sedated donkeys, induced bleeding resulted in significant changes in the hematobiochemical elements, the acid-base status, and blood gas and electrolyte parameters. However, it did not change the markers of inflammation and bone metabolism.

Ultrasonographic evaluation of thoracic and abdominal neoplasia in domestic ruminants: A systemic review.

There is a lack of literature on the usefulness of ultrasonography in the diagnosis and prognosis of thoracic and abdominal neoplasia in domestic ruminants, such as cattle, camels, sheep, and goats. This review aims to shed light on the current applications and prospects of ultrasonography in the diagnosis of thoracic and abdominal neoplasia in domestic ruminants. The scientific literature on ultrasonographic evaluation of the thoracic and abdominal neoplasia in domestic ruminants has been systematically reviewed to verify the potential role of ultrasonography in diagnosing such neoplasia. Based on the literature results, cattle (71.03%) were the most affected animals by thoracic and abdominal neoplasia, followed by sheep (11.86%), goats (11.57%), and camels (5.54%). In all included species, the abdominal neoplasia was more frequent (6.18%) than the thoracic neoplasia (2.97%), and the most frequent neoplasms were forestomach neoplasia. It is concluded that ultrasonography is not widely used in diagnosing thoracic and abdominal neoplasia in ruminant practice. Using ultrasonography in conjunction with guided needle aspiration and biopsy can offer veterinarians the opportunity for more precise diagnosis and treatment decisions guidance of thoracic and abdominal neoplasia in domesticated ruminants.

Depraved appetite in dromedary camels: Clinical, ultrasonographic, and postmortem findings.

Background: Camels are subjected to a wide variety of nutritional deficiencies as they are largely dependent upon grazing desert plants. As a consequence, the syndrome of pica or depraved appetite is occasionally seen in dromedary camels. The condition is manifested as chewing or eating abnormal things such as wood, dirt, bones, stones, clothes, plastics, mud, sand, or other inanimate objects. Aim: This study was designed to investigate the clinical, ultrasonographic, and postmortem findings in dromedary camels with pica or depraved appetite. Methods: Twenty-five camels of 5 days to 15 years were examined. Owner complaints included depraved appetite, loss of body condition, regurgitation of stomach content, and partial or complete absence of feces. Symptoms described were present for a period varying between 3 days, up to 12 months. The stomach compartments and small and large intestines were scanned using ultrasonography from the right and left sides of the abdomen. Necropsy was carried out on six female and three male camels where the thoracic and abdominal organs were examined with special attention to the digestive system. Results: The affected animals had a history of gradual loss of body conditions, eating foreign objects, decreased or total absence of feces, and regurgitation of stomach content. Using ultrasound, the foreign body was imaged occluding completely or partially the intestines. Foreign bodies within the rumen could not be visualized with ultrasound. In cases where the rumen is impacted by sand, small pin-points revealing acoustic enhancement were imaged. Foreign bodies were removed from the rumen at exploratory rumenotomy (n = 11), laparotomy (n = 3), or at necropsy (n = 8) in the form of plastics, cloths, sand, mud, wool balls, robes, glasses, or even metallic objects which may be blunt or sharp. Sixteen (64%) of the camels were recovered while the remaining 9 (36%) did not survive. Conclusion: The syndrome of pica or depraved appetite is an important condition in dromedary resulting in the ingestion of objects other than normal feed. Substantial economic losses are expected as a result of this syndrome. Ultrasonography of the digestive system may help the clinician in some cases to localize of occluding foreign bodies in the intestines, while in the transabdominal scanning of the stomach is valuable only in cases of sand impaction.

The emerging topic of injected cosmetic fillers in the perinasal region of dromedary camels: ultrasonographic and radiographic verification.

Background: Dermal cosmetic fillers have been commonly used in camels in the last few years in Gulf countries. Aim: This study aimed to describe the radiographic as well as sonographic findings of injected cosmetic fillers in Arabian camel perinasal region in beauty shows. Methods: A total number of (n = 11,626) Arabian camels (Camelus dromedarius) were thoroughly investigated for injection of cosmetic fillers in the perinasal area. The age of the camels was 6 months to 10 years, and their weights were 400-650 kg. In parallel, a control group consisting of 30 age/weight-matched non-injected camels was used. Of the 11,626 examined camels, 25 animals (0.0.002%) were injected with cosmetic fillers in the perinasal region. Of the 25 camels, 19 (76%) were females and 6 (24%) were males. Radiographic examinations were carried out for the 25 injected camel perinasal regions. Results: Ultrasonographic examination of the injected perinasal regions revealed precise discrimination of the filler material, which appeared hypo-echogenic in 17 camels (68%) and with anechoic spots in the remaining 8 camels (32%). Variable degrees of swelling caused by the injection of moderate and large quantities of fillers were noted by radiographic assessment, the injected cosmetic filler was precisely diagnosed in the perinasal region as grey in color having soft tissue density in obtained radiographs. Conclusion: In conclusion, radiographic and ultrasonographic examinations are reliable, accurate, and non-invasive diagnostic imaging techniques that can precisely discriminate a filler agent in the soft tissues and determine the situ and size of cutaneous deposits in dromedary camels (C. dromedarius).

Clinical predictive significance of biomarker molecules elevation during the transition period in cattle suffering from different pathological states: A review.

The transition period (TP), which extends from 3 weeks before 3 weeks post parturition, is a critical period regarding the health, productivity, and profitability of dairy animals, during which most health disorders arise, including lameness, mastitis, rumen acidosis, ketosis, hypocalcemia (HC) (milk fever), left-displaced abomasum, fatty liver, hypophosphatemia and post-parturient hemoglobinuria, subacute ruminal acidosis, RP, and metritis. Biomarkers are biological molecules distributed in blood, body fluids, or tissues that represent physiological or pathophysiological indicators of events, processes, or conditions happening within the animal's body. In the field of veterinary medicine, biomarkers are thought to have enormous valuable potential in the field of clinical diagnosis, therapeutical research, surgery, and obstetrical outcome. This review article aims to explore the significance of biomarkers used to predict pathological conditions and health status of cattle during the TP to facilitate the early clinical diagnosis and prompt treatment of TP-related diseases/or conditions and thus improve animal welfare and health and increase productivity.

Abdominal fat necrosis in a female dromedary camel: Clinical, hematobiochemical, sonographic, and pathologic findings.

Background: Abdominal fat necrosis is mostly an incidental finding during rectal examination manifested by the presence of hard necrotic masses of different sizes. Differential diagnosis includes gastrointestinal neoplasia, abdominal abscessation and mummified fetuses. This report describes the clinical, hematological, biochemical, sonographic, and pathologic findings in a female Arabian camel (Camelus dromedaries) with abdominal fat necrosis. Case Description: A 7-year-old female dromedary camel was presented for examination because of weakness and progressive weight loss since months ago. Anthelmintics, analgesics, broad-spectrum antimicrobials, anti-inflammatories and stomachics were administered, but did not result in significant improvement. Preliminary examination of the case revealed emaciation with a body condition score of 2.5 (scale 1-5). The cardiopulmonary, digestive, and urinary systems were evaluated transcutaneously by sonography in the recumbent position. Multiple echogenic masses-located within the intestinal loops were observed alongside few hypoechogenic masses. A hyperechogenic peritoneal effusion and enlarged mesenteric lymph nodes were also detected. Decreased hematocrit value, normocytic normochromic anemia, neutrophilic leukocytosis, hypoalbuminemia, hhyperglobulinemia, hyperglycemia, hyponatremia, and hyperkalemia were detected. A free-hand, ultrasound-guided biopsy was examined histopathologically and revealed multiple abdominal fat necrosis, severe fibrosis, and pancreatitis. Conclusion: It is concluded that, transabdominal ultrasonography in camels was valuable for suspicious of abdominal mesenteric masses and helpful in sampling of a representative biopsy specimen However, histological examination of the biopsy remains the final diagnostic method.

A modified supraorbital surgical approach for enucleation- exenteration in dromedary camels (camelus dromedarius): Clinical study.

Enucleation and exenteration are widely utilized ophthalmic procedures in veterinary field. Enucleation in camels is like other large animals, typically performed under the influence of heavy sedation and loco-regional analgesia. The aim of the current study was to introduce a new surgical approach to enucleate the eye of camels through supraorbital fossa approach. for that purpose, the technique was applied to seven camels referred to the King-fisal teaching veterinary hospital for unilateral enucleation. Assessment of applicability, safety and feasibility of this technique was done. All procedures were performed in the kush (sitting) position under the influence of heavy sedation with Xylazine HCl in combination with retrobulbar nerve block. A "C" shaped skin incision was made in the skin and fascia of the supraorbital fossa to enter the orbital cavity, after which the periorbital fat was gripped, dissected and removed. Bleeding controlled by electrocautery and visible large blood vessels were ligated. After ligation the optic nerve and ophthalmic blood vessels, the eyeball was dissected sharply and freed from the orbital bony attachment. Finally, the orbital fascia and skin were sutured with simple interrupted pattern separately. The approach proved successful in all camels, with the enucleation procedure being both feasible and easily performed. The mean surgical time was approximately 46.6±12.4 minutes. The minimal occurrence of short and long-term complications was encouraging, and the cosmetic outcomes were notably improved. The supraorbital approach is a safe and effective technique for camel ophthalmic surgery, showing advantages in exposure and minimal complications. Further research is needed for validation and broader clinical applications.
