Migrating grass awn within the intraconal part of the retrobulbar space in a dog.

J Small Anim Pract 2021 Mar 2. Epub 2021 Mar 2.

*Clinique vétérinaire Olliolis, 414a chemin des Canniers, Quartier Lagoubran, Ollioules, 83140, France.

A 1.5-year-old MC Cardigan Welsh Corgi was presented for a right oral fistula associated with left tonsil enlargement that responded to medical treatment. A first computed tomography scan was performed and showed no signs of a foreign body. Medical treatment was continued for 2 additional weeks and the dog was free of clinical signs for 3 months. The dog was presented again for a 3-day history of anorexia and marked pain when opening the jaw. The repeat computed tomography scan revealed a migrating foreign body near the optic canal of the right eye, and surgical exploration confirmed that it was trapped within the intraconal part of the retrobulbar space, abutting the optic nerve. The foreign body was surgically removed through an osteotomy of the zygomatic bone. The dog fully recovered with no vision loss. Based on the literature search, this is the first published report describing a migrating grass awn located in the intraconal part of the retrobulbar space, abutting the optic nerve.

Lung lobe torsion in 15 dogs: Peripheral band sign on ultrasound.

Vet Radiol Ultrasound 2021 Jan 31;62(1):116-125. Epub 2020 Oct 31.

AZURVET Referral Center, Saint-Laurent-du-Var, France.

The diagnosis of lung lobe torsion in dogs is usually based on radiological, endoscopic, and CT features. Few ultrasonographic descriptions have been published. The purpose of this multicenter, retrospective, and prospective observational study was to investigate the presence of a hypoechoic area forming a pulmonary band or line at the periphery of the twisted lobe on ultrasonography and assess its significance by comparing it to CT and histological findings. Fifteen dogs with lung lobe torsion confirmed surgically or postmortem were included. All had received ultrasonography and CT examinations; 13 had additional histopathological examination performed. In 14 cases, thoracic ultrasonography revealed a peripheral hypoechoic band, overlying areas of scattered, hyperreflecting interfaces in the affected lobe. On CT, central emphysema was surrounded by a peripheral, soft tissue attenuation band, affecting the periphery in 14 cases. No band was observed in one case, in which the lobe was entirely consolidated. Histological examination yielded a comparable peripheral band, consisting of a thickened visceral pleura with or without hemorrhagic necrosis of the underlying pulmonary parenchyma. This peripheral band may be related to the specific fractal organization of airways and vessels, which plays an important role in lung perfusion and ventilation and makes the lung periphery more prone to ischemia. Our findings suggest that the presence of a peripheral hypoechoic band, associated with central emphysema in a noncollapsed lung lobe on ultrasonography, is suggestive of compromised blood supply and air flow, and lung lobe torsion should therefore be suspected.

Computed tomographic characteristics of pneumolabyrinth in a French bulldog with otitis media and externa.

Vet Radiol Ultrasound 2019 Sep 1;60(5):E58-E61. Epub 2017 Dec 1.

AZURVET Referral Center in Veterinary Diagnostic Imaging, Neurology, Cardiology, Cagnes-sur-Mer, 06800, France.

A four-year-old female French bulldog was presented for evaluation of acute, left-sided peripheral vestibular syndrome. Computed tomographic (CT) examination of the head revealed the presence of air within the left cochlea and vestibule, consistent with pneumolabyrinth. This was concurrent with ipsilateral otitis media and externa. Pneumolabyrinth is an uncommon finding in humans and is most frequently due to head trauma and temporal bone fracture. This is the first report describing pneumolabyrinth in a dog, apparently of nontraumatic origin in this case.

Intra- and inter-observer variability in ultrasonographical measurements of the uterus and ovaries in healthy, non-pregnant queens.

J Feline Med Surg 2016 Feb 18;18(2):110-7. Epub 2015 Mar 18.

Azurvet Center, Cagne sur mer, France.

Objectives: We aimed to (1) evaluate how frequently the uterus and ovaries of healthy, non-pregnant queens are visible; (2) describe their appearance; (3) take their measurements; and (4) determine intra- and inter-observer variabilities in their measurements. We hypothesised that, using a high-frequency linear probe, the uterus and ovaries could be ultrasonographically visualised during any period of the sexual cycle and with any level of operator expertise.

Methods: Eight queens were enrolled in the study and the ultrasonographical appearance of their uterus and ovaries assessed with a high-frequency linear probe of 15-19 MHz. The diameter of the uterine horns, body and cervix in transverse and longitudinal sections, and the length of the ovaries were recorded. Three observers of different expertise level participated in the study, and the differences between the separate measurements made per queen were evaluated.

Results: The ovaries and the entire uterus were visualised in every queen. The ovaries were ovoid structures with submillimetric follicles during anoestrus and additional larger follicles depending on the stage of the cycle. An ovarian pattern suggesting cortex and medulla was observed in half the cases. In the uterus, the serosa was a thin hyperechoic outer rim, and layering was observed in half the cases. The cervix was difficult to identify. The intra- and inter-observer variabilities in the uterine horns and the ovaries were minimal (coefficient of variation [CV] 1.4-4.1%) compared with the differences within the queens (CV 10.9-43.4%). The longitudinal and transverse measurements of the horns and the uterine body were the same.

Conclusions And Relevance: The ovaries and uterine horns in queens are accessible ultrasonographically at any stage of their cycle, and can be measured with low intra- and inter-observer variabilities.

Alcohol percutaneous neurolysis of the sphenopalatine ganglion in the management of refractory cranio-facial pain.

Neuroradiology 2014 Jul 26;56(7):589-96. Epub 2014 Apr 26.

Neuroradiology Department, Grenoble University Hospital, Grenoble, France,

Introduction: The sphenopalatine ganglion (SPN) has been proven to be involved in various types of facial pain syndromes. Management of these cranio-facial pain syndromes can be challenging, and existing specific treatments are sometimes inefficient and may fail. The purpose of this study is to describe and evaluate alcohol SPN in the management of cranio-facial pain.

Methods: Forty-two patients suffering from refractory facial pain who underwent 58 consecutive SPN were included in this study between 2000 and 2013. Patients were divided into three groups: group "cluster headache" (CH), group "persistent idiopathic facial pain" (PFIP), and group "Other". Pain was assessed using Visual Analogue Scale scores (measured immediately before and after procedure and at regular intervals following the procedure). Alcohol SPN was considered to be effective when pain relief was equal to or greater than 50 % and lasting for at least 1 month. All procedures were realized ambulatory under CT guidance and consisted of an injection of 1 ml of absolute alcohol.

Results: Overall efficacy rate of alcohol SPN was 67.2 %, with mean pain relief duration of 10.3 months. Procedure was graded either not painful or tolerable by patients in 64.2 %. Analysis showed a higher efficacy rate in the groups CH (76.5 %) and PFIP (85.7 %) compared to the group Other (40 %). No difference was found between groups regarding the recurrence rate.

Conclusion: Alcohol SPN under CT guidance appears as a safe and effective treatment of refractory facial pain, especially in cases of cluster headache and persistent idiopathic facial pain.

Ultrasonographic characteristics of the abdominal esophagus and cardia in dogs.

Vet Radiol Ultrasound 2014 Sep-Oct;55(5):552-60. Epub 2014 Mar 16.

Azurvet, Referral Center in Veterinary Diagnostic Imaging and Neurology, 06800, Cagnes-sur-Mer, France.

Differential diagnoses for regurgitation and vomiting in dogs include diseases of the gastroesophageal junction. The purpose of this cross-sectional study was to describe ultrasonographic characteristics of the abdominal esophagus and gastric cardia in normal dogs and dogs with clinical disease involving this region. A total of 126 dogs with no clinical signs of gastrointestinal disease and six dogs with clinical diseases involving the gastroesophageal junction were included. For seven euthanized dogs, ultrasonographic features were also compared with gross pathology and histopathology. Cardial and abdominal esophageal wall thicknesses were measured ultrasonographically for all normal dogs and effects of weight, sex, age, and stomach filling were tested. Five layers could be identified in normal esophageal and cardial walls. The inner esophageal layer was echogenic, corresponding to the cornified mucosa and glandular portion of the submucosa. The cardia was characterized by a thick muscularis, and a transitional zone between echogenic esophageal and hypoechoic gastric mucosal layers. Mean (±SD) cardial wall thicknesses for normal dogs were 7.6 mm (±1.6), 9.7 mm (±1.8), 10.8 mm (±1.6), 13.3 mm (±2.5) for dogs in the <10 kg, 10-19.9 kg, 20-29.9 kg and ≥30 kg weight groups, respectively. Mean (±SD) esophageal wall thicknesses were: 4.1 mm (±0.6), 5.1 mm (±1.3), 5.6 mm (±1), and 6.4 mm (±1.1) for the same weight groups, respectively. Measurements of wall thickness were significantly correlated with dog weight group. Ultrasonography assisted diagnosis in all six clinically affected dogs. Findings supported the use of transabdominal ultrasonography as a diagnostic test for dogs with suspected gastroesophageal disease.

CT-guided stellate ganglion blockade vs. radiofrequency neurolysis in the management of refractory type I complex regional pain syndrome of the upper limb.

Eur Radiol 2013 May 9;23(5):1316-22. Epub 2012 Nov 9.

Radiology Department, University Hospital CHU Gabriel Montpied, 63000 Clermont-Ferrand, France.

Objective: To describe and evaluate the feasibility and efficacy of CT-guided radiofrequency neurolysis (RFN) vs. local blockade of the stellate ganglion in the management of chronic refractory type I complex regional pain syndrome (CRPS) of the upper limb.

Methods: Sixty-seven patients were included in this retrospective study between 2000 and 2011. All suffered from chronic upper limb type I CRPS refractory to conventional pain therapies. Thirty-three patients underwent stellate ganglion blockade and 34 benefited from radiofrequency neurolysis of the stellate ganglion. CT guidance was used in both groups. The procedure was considered effective when pain relief was ≥50 %, lasting for at least 2 years.

Results: Thirty-nine women (58.2 %) and 28 men (41.8 %) with a mean age of 49.5 years were included in the study. Univariate analysis performed on the blockade and RFN groups showed a significantly (P < 0.0001) higher success rate in the RFN group (67.6 %, 23/34) compared with the blockade group (21.2 %, 7/33) with an odds ratio of 7.76.

Conclusion: CT-guided radiofrequency neurolysis of the stellate ganglion is a safe and successful treatment of chronic refractory type I CRPS of the upper limb. It appears to be more effective than stellate ganglion blockade.

Key Points: • Complex regional pain syndrome is painful, disabling and often refractory to treatment. • Sixty-seven percent of patients had lasting pain relief (2 years) after radiofrequency neurolysis. • Retrospective study showed a significantly higher success rate for radiofrequency neurolysis. • CT guidance is mandatory for a successful and safe procedure.

[A traditional anesthesia consultation or a "telephone interview" within the framework of ambulatory surgery?].

Cah Anesthesiol 1993 ;41(5):459-61

Clinique Sainte-Croix, Le Mans.

Unlabelled: Preoperative assessment for anaesthesia must detect in the setting of ambulatory surgery both medical and sociopsychologic problems which may contraindicate the ambulatory aspect of the procedure. The goal of our prospective study was to assess the efficacy of a preoperative telephone interview in screening the medical and sociopsychologic problems of ambulatory patients. 1,000 consenting consecutive outpatients participated to the study and were randomly allocated to one of two groups: patients in the standard group (STD) had a consultation a few days before surgery whereas those in the telephonic group (TEL) called the anesthetist a few days before, the physical exam being performed on the day of surgery. The cancellation of the ambulatory procedure was decided upon either medical criterias (MC) or sociopsychologic criterias (from Waetchler).

Results: both groups were comparable regarding SPC and MC but prescription of preoperative tests was more frequent in the STD group (result statistically significant). In conclusion, this new approach is as reliable as the standard consultation in screening the SPC which remain the most frequent cause of cancellation in ambulatory surgery. Therefore this telephonic interview which is simple and reliable for screening outpatients may represent a suitable alternative to a standard consultation.

Resistance to sodium nitroprusside in hypertensive patients.

Crit Care Med 1982 May;10(5):301-4

Eleven patients in hypertensive crisis were treated with iv sodium nitroprusside (SNP). In all cases, rapid clinical improvement was obtained. Nevertheless, 9 patients developed progressive resistance to the hypotensive effect of the drug. For the first 2 h, the mean infusion rate was 1.68 +/- 0.64 micrograms/kg . min. For the next 6 h, the mean infusion rate had to be increased to 3.1 +/- 1.14 micrograms/kg . min in order to maintain diastolic blood pressure below 110 mm Hg. Hemodynamic measurements demonstrated that this resistance was related to a marked rise in cardiac index without tachycardia. In the 6 patients with pulmonary edema who developed resistance to SNP, blood pressure control was obtained by fluid depletion. In the 3 patients without pulmonary edema who developed resistance to SNP, blood pressure control was obtained by iv acebutolol. The authors conclude that SNP rapidly improves critical hypertension. Progressive resistance to the hypotensive effect of the drug can occur in some cases and is related to a marked rise in cardiac index, which can be rapidly antagonized with fluid depletion or a beta-blocking agent to avoid SNP accumulation and cyanide toxicity.

[Nitrous oxide and pressures exerted on the trachea by endotracheal tubes. Study on a tracheal model].

Ann Fr Anesth Reanim 1982 ;1(5):491-5

The authors studied the effects of nitrous oxide diffusion, using a tracheal model, on the pressure of several endotracheal tube cuffs. Studies carried out showed an increase in volume and pressure of the cuffs related to time exposure and nitrous oxide concentrations used. Use of a self-controlled pressure cuff or filling the cuff with inspired gas composition should be of value to counteract or to prevent the diffusion effect.

[Droperidol. Action on hemodynamic and oxygen consumption changes (author's transl)].

Anesth Analg (Paris) 1980 ;37(5-6):229-32

Hemodynamic and oxygen consumption changes following general anesthesia were studied in 11 patients who did and in 11 patients who did not received droperidol at the end of operation. Both group were similar with respect to age, duration of anesthesia, doses of anesthetic drugs, and hemodynamic and oxygen consumption values immediately at the end of operation. The highest oxygen consumption measurements which were selected as representative of the maximal metabolism of the recovery period showed that the following parameters were lower in the droperidol group than in the non-droperidol group: oxygen consumption (162 +/- 12 and 238 +/- 19 ml/min/m2 respectively), cardiac index (3.0 +/- 0.2 and 4.4 +/- 0.4 l/min/m2), mean arterial pressure (11 +/- 6 and 129 +/- 5 torr), stroke index (27 +/- 3 and 46 +/- 4 ml/m2) left ventricular stroke work index (38 +/- 5 and 77 +/- 8 gm/m2) and PaCO2 (39 +/- 2 and 49 +/- 2 torr). The measurements performed after extubation were similar in both groups. These data show a metabolic and hemodynamic stabilizing effect of droperidol during recovery which may be useful in high-risk patients.

Cardiovascular response to the i.v. administration of morphine in critically ill patients undergoing IPPV.

Br J Anaesth 1979 Nov;51(11):1071-7

The haemodynamic changes following the administration of morphine 0.15 and 0.30 mg kg-1 i.v. were studied in 11 patients, free from known cardiac disease. All patients were acutely ill and their lungs were being ventilated mechanically. In those patients receiving 0.15 mg kg-1, the only haemodynamic change was a slight and transitory decrease in the systolic arterial pressure. In contrast, several changes were observed in patients receiving 0.30 mg kg-1: an immediate and prolonged decrease in the cardiac index was noted along with transient decreases in heart rate, stroke volume index, arterial pressure and left stroke work index. These results suggest that the haemodynamic cost of morphine 10 mg is negligible but could be significant when 20 mg has been administered and must be weighed against its beneficial effects in the critically ill patient.

Hemodynamic effects of dopamine in septic shock with and without acute renal failure.

Arch Surg 1978 Dec;113(12):1414-6

Hemodynamic response to dopamine hydrochloride in septic shock with myocardial dysfunction was studied in ten patients with normal renal function (group 1) and in ten patients with acute renal failure (group 2). The control hemodynamic data were similar in the two groups. Dopamine in groups 1 and 2 induced significant (P less than .01) and similar increases in cardiac index and mean aortic pressure. Group 1 had a smaller increase in heart rate (+ 16%), than group 2 (+ 24%), but this difference was not significant. Stroke volume index had a significant increase in group 1 (+ 18%), whereas it did not increase significantly in group 2 (+ 4%); this difference of changes in stroke volume index between the two groups was significant (P less than .01). This phenomenon suggests an increased chronotropic effect and/or a reduced inotropic effect of dopamine in patients with septic shock and acute renal failure.

Haemodynamic effects of dopamine in septic shock.

Intensive Care Med 1977 Aug;3(2):47-53

The Haemodynamic response to dopamine infusion has been assessed in 30 patients in septic shock with myocardial dysfunction. Dopamine infusion resulted in a haemodynamic improvement as indicated by significant increases in cardiac output of 38.4% (p less than .001), stroke volume 18.7% (p less than .001), and mean arterial pressure of 33% (p less than .001). Despite the inotropic effect, left ventricular filling pressure did not change in 20 cases and increased in 10 cases. Mean peripheral resistance remained unchanged with a scatter of individual responses depending upon factors such as dopamine dose and initial vascular resistance. Dopamine increased intrapulmonary shunting by 48% (p less than .001), insignificantly decreased PaO2, increased mixed venous oxygen saturation by 16% (p less than .02) and decreased pulmonary vascular resistance by 15% (p less than .02). Both isoprenaline and dopamine improve stroke volume by an inotropic action, with an increase in venous return in the case of the latter and a reduction in afterload in the former. It is concluded that the usefulness of dopamine in septic shock may be limited in patients with previous myocardial disease because of the risk of increasing preload and in hypoxaemic patients because of the risk of increasing intrapulmonary shunting.
