A Comparasion of Laboratory and Cardiopulmonary Effects of Desflurane, Detomidine and Medetomidine Anaesthetic Combinations in Horses

Background: Equine anesthesia morbidity and mortality rates are greater than in other domestic animals because of hypotension and hypoventilation. The important features desired in general anesthesia for horses are a rapid effect, rapid emergence and balanced anesthesia. The long duration of action of currently used anesthetic agents cause various complications in horses. The aim of the present study was to compare the clinical effects of combination of the anesthetics desflurane, detomidine and medetomidine in horses.Materials, Methods & Results: Eight healthy mixed-breed horses (four males and four females) with weighing 275 ± 56 kg [mean ± standard deviation (SD)] and aged 6.8 ± 5 years [(mean ± SD)] were used for this study. The horses were placed into one of four groups: group I (detomidine-desflurane), group II (detomidine-desflurane-atipamezole), group III (medetomidinedesflurane), or group IV (medetomidine-desflurane-atipamezole). Horses were rested for 15 days before each group starts to study. Intravenous detomidine (25 µg/kg) was used for premedication in groups I and II, and intravenous medetomidine (7 µg/ kg) was used for premedication in groups III and IV. Ketamine hydrocholoride (2 mg/kg) and midazolam (0.03 mg/kg) were intravenously administered in the same syringe to induce anesthesia. After induction of anesthesia, horses were placed in the left lateral recumbent position, and the trachea was intubated with a cuffed endotracheal tube with an internal diameter of 28 mm. The endotracheal tube was attached to a large animal circle breathing system anesthesia machine, and anesthesia was maintained with desflurane for 90 min. The initial dosage of desflurane was 14% + 4 L O2/min, and was reduced by 2% every 10 min over the first 30 min of anesthesia. After 30 min, the desflurane dose was changed to 8% + 4 L, which was maintained until the end of anesthesia (90 min). After 90 min, the administration of desflurane was discontinued, and all animals were supported by O2, with groups II and IV receiving 0.06 mg/kg atipamezole in addition to oxygen. Anaesthetic action times, hematological parameters, blood gas levels, electrolyte levels, biochemical values, electrocardiography values and end-tidal carbon dioxide volume were measured before, during, at the end of, and 24 h after anesthesia.Discussion: In this study, medetomidine (7 µg/kg) and detomidine (25 µg/kg) were intravenously administered, which was adequate and suitable for sedating horses. At the end of anesthesia, 0.06 mg/kg atipamezole was intravenously administered in groups II and IV. However, atipamezole did not affect the clinical parameters. Stress, excitement, fear, catecholamine exchange in blood circulation, hyperglycemia, and hypoxia can all cause changes in venous blood parameters. These are potential reasons for the changes in venous blood parameters (i.e., WBC and Hb) observed at the beginning of and during anesthesia in the present study. During and after the anesthetic period, serum biochemical values can be different from baseline values. They are dependent on the effects of anesthetic agents. During anesthesia, the decrease and increase of biochemical values stabilize the changes in the enzyme system that develops because of the effects of anesthetic agents. In the present study, it was considered that the changes in the biochemical values aimed to stabilize the changes induced by anesthesia. Regarding the electrolyte parameters evaluated in the study, there was a statistical difference detected in Na values between 90 min after induction of anesthesia and 24 h after induction of anesthesia in group IV. However,  in previous studies, the changes in Na values did not influence the cardiac pressure during general anesthesia. In our study, significant changes were not seen in any electrolyte parameters except Na, and atrioventricular block was not detected in ECG traces. Generally, decreased ETCO2 levels are evidence of lung perfusion deficiency. It depends on the effects of anesthetic agents on the cardiopulmonary, cardiovascular, and respiratory systems. In particular, the higher pressure and dose of desflurane supress respiratory system. Oxygen supplementation in general anesthesia increases respiratory rate, but a-2 agonists and ketamine-midazolam effects can eliminate the increasing respiratory rate in general anesthesia

Effect of gallic acid on liver injury during obstructive cholestasis after bile duct ligation in rat

Aim: To investigate the hepatoprotective, anti-inflammatory and antioxidant effects of gallic acid (GA) against obstructive cholestasis (OC) -induced liver damage in rats. Methods: Thirty female Sprague-Dawley rats were divided into three groups. Group 1 (n=10) was the sham-operated group. In group 2 and group 3, hepatoduodenal ligament dissection was performed after laparotomy. Once the common bile duct was made apparent, it was ligated with 4/0 silk surgical suture and cut between both sutures. Group 2 (n=10) was the control group. Group 3 (n=10) was the GA group. GA (50 mg/kg) was administered by oral gavage daily for 10 days. At the end of the experiment on day 10, the rats were anesthetized. Fibrosis, inflammation, ductal proliferation and necrosis were evaluated histopathologically. Serum levels of AST, ALT, TBIL, DBIL, LDH and GGT levels were determined. In the serum and liver, TAS, TOS, MDA, TNF-α, IL-1, IL-6, and IL 10 levels were evaluated.         Results:  When group 2 and group 3 were compared histopathologically, fibrosis and inflammation were significantly lower in group 3. In group 3, all LFTs (except DBIL), liver and serum IL-6, IL-1, TOS, MDA, and TNF-α levels were significantly lower than group 2, whereas IL-10 and TAS values were increased. Conclusion: Findings of this research indicate that GA may be effective against OC-induced liver damage in a rat model. We presume that the beneficial effects of GA are closely associated with its antioxidant and anti-inflammatory activities. Therefore, we think that using GA   can save us time before resorting to the surgical method

Ani işitme kaybında internal akustik kanal çapı

Objective: The purpose of our study was to determine the corelation between internal acoustic channel diameter and idiopathic sensorineural hearing loss. Material and Method: We defined sudden sensorineural hearing loss according to the criteria of Wilson as a 30-dB sensorineural hearing loss occurring in at least three contiguous frequencies in less than 3 days. The internal acoustic channel diameter all of the patients was measured from three dimensional temporal CT scan. Results: Of the 15 patients, 7 were male and 8 were female, ranging in age from 17 to 59 and the mean age was 39.6 years. The right ear was involved in 6 patients, and the left ear in 9. There was no statistically significant difference between the patients’ affected and intact ears (p>0.05). However, the mean diameter of affected side of the patients was narrower than those of healthy controls (p0.05). Ancak kontrol grubuyla karşılaştırıldığında etkilenen kulakta istatistiksel olarak anlamlı darlık tespit edildi (p<0.05). Sonuç: Bulgularımız kontrol grubuyla karşılaştırıldığında, idiyopatik ani işitme kaybı gelişen hastalarda internal akustik kanal çapının nispeten daha dar olduğunu ve bunun bir risk faktörü olabileceğini düşündürmektedir

The value of hematological inflammatory parameters in the differential diagnosis of testicular torsion and epididymo-orchitis in children

Aim: To investigate the value of neutrophil lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR) in differentiating acute scrotal conditions. Methods: A total of 60 patients, including 30 epididymo-orchitis and 30 testicular torsions, diagnosed and treated in our clinic between January 1, 2010 and December 2022, were included in the study. The patients were divided into two groups; group 1 (testicular torsion = TT) and Group 2 (epididymo-orchitis = EO). The age, diagnosis, and hemogram parameters of the patients were evaluated. Results: Both Group 1 and Group 2 consisted of 30 patients each. The mean ages of group 1 and 2 were 13.7, and 11.2 years, respectively (p&gt;0.05). When compared to the group 2, NLR was higher in the group 2 (p&lt;0.05). There was no statistically significant difference between the groups in terms of PLR value (p &gt;0.05). ROC analysis was performed for NLR. According to the ROC analysis; at a cut-off value of 2.92, the sensitivity was 51% and the specificity was 87%, AUC (0.79; CI: 0.694 - 0.896). Conclusion: TT and EO can be diagnosed using inflammatory markers such as NLR. However, additional prospective studies are neede

Protective effects of cordycepin on the histopathological changes and oxidative stress induced by hepatic ischemia/reperfusion in rats

Aim: To investigate the effects of cordycepin on the histopathological changes and oxidative stress induced by hepatic ischemia/reperfusion (I/R) in rats. Method: Forty male Wistar rats were randomly divided into 4 groups as group I (sham, n=10), group II (control, n=10), group III (I/R-untreated, n=10) and group IV (I/R-cordycepin, n=10). Liver ischemia was induced for 30 min then reperfusion was allowed for 1 h. At the end of the experiment, liver specimens and blood samples were taken for histopathological and antioxidant evaluations, and biochemical analysis. Results: The levels of IL6, IL-1β, and TNFα in the serum and liver tissues were higher in the I/R-untreated group compared to the I/R-cordycepin treated group. In the I/R-cordycepin group, serum MDA levels were decreased compared with the I/R-untreated group. The I/R-cordycepin treated group showed an increase in TAS levels, and a decrease in TOS levels compared with I/R-untreated group. The histopathological injury score were significantly lower in the I/R-cordycepin treated group compared to the I/R-untreated group.&nbsp; In the I/R-untreated group, the integrity of the hepatocyte cell lines deteriorated. Mononuclear inflammatory cells infiltrated the parenchyma regions, the sinuses dilated and there was diffuse congestion Preoperative treatment with cordycepine reduced histopathological abnormalities. Conclusion: Cordycepin has demonstrated significant hepatoprotective effects against I/R injury induced in rats through TAS elevation and reduction of TOS, MDA and proinflammatory cytokines

Jejuno-ilealna perforacija i volvulus uzrokovani višekratnim gutanjem magnetnih stranih tijela

Foreign body ingestion is a common problem in children, but magnet ingestion is relatively rare. However, when it occurs, it tends to have a high rate of complications. This is a case report of a 3-year-old child who swallowed multiple magnetic toys, subsequently developing jejunoileal perforation and volvulus. This case report indicates that it is best to surgically remove multiple ingested magnets without delay to avoid intestinal perforation, fistula, and other complications such as volvulus.Gutanje stranog tijela čest je problem u djece, no gutanje magneta je relativno rijetko. Međutim, kad se to dogodi obično je praćeno visokom stopom komplikacija. U ovom prikazu slučaja opisuje se trogodišnje dijete koje je progutalo mnoštvo magnetnih igračaka, što je izazvalo jejuno-ilealnu perforaciju i volvulus. Ovaj prikaz slučaja pokazuje da je najbolje bez odlaganja kirurški odstraniti takve progutane magnete kako bi se izbjegla perforacija crijeva, fistule i druge komplikacije kao što je volvulus

Absolute White Blood Cell Count and Neutrophil-Lymphocyte Ratio May Predict the Need for Double- J Stent Insertion in Ureteral Stones in Children: A Comparative Study

Objective: Our goal was to determine whether or not a double-J (DJ) stent insertion is required in cases of ureteral stones based on the absolute white blood cell (WBC) counts, neutrophillymphocyte ratio (NLR), absolute monocyte counts, and other laboratory markers. Materials and Methods: The patients were divided into two groups as those who did (Group 1), and did not (Group 2) need DJ stent insertion. The age, symptoms, diagnosis, hemogram parameters, and treatment results of the patients were evaluated. Results: Forty-nine percent (n=44) of the patients were female and 51% (n=46) were male. The groups did not differ in terms of age and gender (p>0.05). A higher incidence of hematuria was observed in Group 1 (p<0.05). WBC (p<0.05), NLR (p<0.05), and monocyte counts (p<0.05) were found to be higher in Group 1. In the ROC analysis; WBC and NLR were found to be two predictive markers for the need for DJ stent insertion. At a cut-off value of 12.6 x 109/L, WBC had 37% sensitivity, and 81% specificity (AUC: 0.67; 95% CI: 0.54-0.80), and at a cut-off value of 3.8, NLR had 65% sensitivity, and 76% specificity (AUC: 0.70; 95%CI: 0.57-0.82) in predicting the need for a DJ stent insertion. Reoperation was not required in any case. Conclusion: In cases of ureteral stones, the absolute WBC count and NLR may help determine the requirement (if any) for a double-J stent insertion

Collet-Sicard Syndrome Associated with Occipital Condyle Fracture and Epidural Hematoma

A 31-year-old male was presented with a very rare case of ipsilateral palsies of the nerves IX through XII (Collet-Sicard syndrome) after a closed head injury. An occipital condyle fracture that was associated with epidural hematoma was diagnosed by computed tomography. The patient was conservatively managed, and following the treatment, partial neurological recovery ensued. The phenomenon of occipital condyle fracture involving the last four cranial nerve palsies is relatively rare. Although 3 cases of Collet-Sicard syndrome that were caused by an occipital condyle fracture has been reported, the association between condyle fracture and epidural hematoma has never been described before
