Respiratory distress is a common presentation in veterinary medicine, and prompt, effective management is paramount. Treating these animals can be challenging, as many are too distressed to be handled extensively. Excessive manipulation can result in exacerbation of respiratory distress, haemoglobin desaturation and respiratory arrest. Thus, in unstable animals, it is very important to limit diagnostic testing. Instead, initial efforts should be focused on stabilization and application of non-specific respiratory support modalities, such as oxygen supplementation. The history and signalment, observation of the pattern of respiration, and a brief physical examination are all used to make a clinical estimate of the anatomical location of disease within the respiratory tract, thereby directing effective emergency therapy to stabilize the patient prior to diagnostic testing. Depending on the cause of respiratory distress, a variety of emergency interventions may be necessary, including drug therapy, tracheostomy, thoracocentesis or thoracostomy tube placement, and positive pressure ventilation. This chapter looks at Physiology; History; Initial observation; Physical examination; Initial stabilization; Initial management based on disease location; and Initial diagnostic tests.

В статті викладений диференціальний підхід до принципів інтенсивної терапії гострого респіраторного дистрес-синдрому (ГРДС) залежно від причин виникнення, терміну від початку хвороби і провідних патогенетичних механізмів. Наведені цілі респіраторної підтримки, абсолютні та відносні показання для початку респіраторної терапії при ГРДС. Вказано, що респіраторна підтримка в різних режимах є методом тимчасового протезування функції зовнішнього дихання, надає час для відновлення адекватності функції легень.

A 56-year-old man presented to the orthopedics department with chronic shoulder pain for 4 years not relieved by medication or physiotherapy. On physical examination, there was no restriction of movement, and there was focal tenderness over the lateral aspect of the clavicle. Magnetic resonance (MR) imaging, showed a well-defined T1 hypointense lesion [Figure 1a, arrow], which was hyperintense on short T1 inversion recovery images [Figure 1b, arrow]. The lesion was smaller than 1 cm, showed homogeneous enhancement in postcontrast T1-weighted images [Figure 1c, arrow] and was superior to the distal end of the clavicle in the subcutaneous plane. There was no obvious communication of the lesion with either the acromioclavicular or glenohumeral joint. There was no erosion, remodeling, or sclerosis of the superior clavicular surface. The fat planes with all 14 surrounding structures were maintained. Correlative ultrasound revealed a well-defined, homogenously hypoechoic lesion [Figure 1d, asterisk] with minimal intralesional vascularity [Figure 1d, arrow]. Surgical excision of the lesion resulted in complete disappearance of symptoms and follow-up imaging showed no recurrence.Figure 1: (a) T1-weighted Magnetic resonance image showing a well-defined hypointense lesion (arrow) superior to the distal end of the clavicle.

Glomus tumor was first described by Wood in 1912, but the correct origin was clarified as hyperplasia of a normal glomus body by Masson in 1924 [2]. Classic glomus tumors are typically solitary. They are most commonly smaller than 1 cm and located in the upper extremities, especially the hands and subungual regions [3]. Glomus tumor is a hamartoma that develops from a neuromyoarterial glomus body and consists of dilated vascular channels surrounded by proliferating glomus and nerve cells. There is no sex predilection and the most common age at presentation is 20–40 years [4]. It is rare in certain locations such as the extremities, trunk, and viscera. The forearm is the most common extradigital location, with the shoulder and back the least common. Clinical manifestations include paroxysms of pain, cold sensitivity, and point tenderness with signs of hyperesthesia, muscle atrophy, or osteoporosis in the affected area. We presented imaging findings in a rare case of glomus tumor with chronic shoulder pain. Malignant transformation is rare. Hemangiomas are a close imaging differential for glomus tumors [5]. Ultrasound findings include a cystic/solid hypoechoic mass and rarely, erosion of the underlying bone. Intratumoral vascular shunts are noted in color Doppler imaging. MR imaging shows an intermediate or low-signal intensity on T1-weighted images, marked hyperintensity on T2-weighted images, and strong postcontrast imaging. MR angiography shows a focus of strong enhancement in the arterial phase and tumor blush, which progressively increases in size in the delayed phase. The treatment of choice for glomus tumors is complete excision, and even in cases of malignant transformation, no chemotherapy or radiation is needed [6]. Glomus tumors are neoplasms that arise from modified smooth muscle cells of the glomus body, which is a specialized form of an arteriovenous anastomosis that plays a significant role in the regulation of skin circulation. The present study reports a case of a glomus tumor in a man with chronic shoulder pain for 4 years. A correct clinical diagnosis was obtained from imaging modalities (ultrasound and MR imaging). Declaration of patient consent The authors certify that the patient consent form has been obtained. In the form, the patient has given his consent for his images and other clinical information to be reported in the journal. The patient understands that his name and initial will not be published and due efforts will be made to conceal their identity, but anonymity cannot be guaranteed.
