Practice and Perception of Radiographers on the Positioning Techniques of Erect Lateral Cervical Spine Radiography in Non-trauma Adult Patients

Background: The visualization of the lower cervical spine (C-spine), including the C7-T1 junction on lateral radiograph is a challenge due to the overlapping of the shoulder girdle. Therefore, the radiographers have adapted different positioning strategies to overcome this challenge. This study explores the current practice and perception of radiographers on positioning techniques of erect lateral cervical spine radiography in non-trauma adult patients. Methods: This prospective study was conducted with a self-administered, structured questionnaire distributed among 50 radiographers working in four selected hospitals in Sri Lanka. Results: The radiographers used weight-bearing and non-weight-bearing positioning techniques for the erect lateral C-spine radiography. Most of them employed the standing breath-holding technique for image acquisition with or without exertion. While 54% of the radiographers utilized two water-filled cans during the weight-bearing technique, 82% used holding arms back with the shoulders down and pulling as low as possible in the non-weight-bearing technique. In addition, 88% of the radiographers believed that the weight-bearing position could increase the visibility of the C-spine. Almost all the radiographers (100%) stated that correct positioning instruction could improve the visibility of the C-spine. Conclusion: Radiographers have mainly used two positioning techniques of weight-bearing and non-weight-bearing for erect lateral C-spine radiography for non-trauma adult patients. In addition, most radiographers had a positive attitude toward the weight-bearing technique in the evaluation of lateral C-spine. These results highlight the importance of conducting studies to evaluate the effectiveness of the weight-bearing technique in erect lateral C-spine radiography.

Analysis of long-term results of surgical treatment of acromioclavicular dislocation

Background. Acromioclavicular dislocation is a fairly common traumatic injury of the musculoskeletal system, and according to different authors varies from 2 to 26.1 % dislocations of other localizations, and is about 10 % of all acute injuries of the shoulder girdle, taking 3rd place after dislocations of shoulder and forearm. The social significance of this damage is determined by the occurrence mainly among young working-age men. The work was aimed to identify factors that cause unsatisfactory anatomical and functional results after surgical treatment of acromioclavicular dislocations. Materials and methods. This retrospective study (2015–2020) included 93 patients who had surgical intervention for acromioclavicular dislocation. Surgical stabilization of the acromial end of the clavicle was done by Hook Plate and by Weber technic. Results. The outcome of research shows that 49.5 % of cases had good results, 31.2 % — satisfactory, and 19.3 % — poor. There is a direct correlation between unsatisfying outcome and increased severity of the injury. The study found that 9.7 % of unsatisfying results were associated while using Weber’s technic in the Tossy II, while in Tossy III, it was 27.0 %. A similar correlation was found while using Hook Platе, in the case of Tossy II, unsatisfying results were in 15.8 % of cases and Tossy III — 29.4 %. Conclusions. The reason for the unsatisfying results of the surgical acromioclavicular dislocations treatment is the severity of damage and the absence of an algorithm for diagnosis and management of this injury. In Tossy III dislocations, the use of stabilization methods as Weber’s technic, Hook Plate, or suturing damaged acromioclavicular ligaments did not demonstrate satisfying effectiveness.

The Importance of Type D Personality in the Development of Temporomandibular Disorders (TMDs) and Depression in Students during the COVID-19 Pandemic

Background: a type D personality is a factor in a person’s susceptibility to general mental stress, especially during the COVID-19 pandemic. Although many studies were conducted on the relationships among stressful situations, an individual’s personality, depression, and the occurrence of various diseases, e.g., cardiovascular disease or cancer, there are no analogous data on people with temporomandibular disorders (TMDs). Aim: the assessment of TMDs and depression symptoms in students with type D personality. Material and Methods: the research was carried out with the participation of 240 physiotherapy students. The study group (G1) consisted of 120 participants with type D personalities, the control group (G2) consisted of the same number of participants, without “stress” personalities. All subjects were assessed for the occurrence of TMD symptoms, as well as for depression and anxiety symptoms, using the Beck Depression Inventory (BDI), based on the proprietary questionnaire. Results: in students with type D personality symptoms, TMDs occurred significantly more often and in greater number (p = 0.00) than in those without stress personalities. The exception was the symptom of increased muscle tension, which showed no statistical difference (p = 0.22). Among the 240 respondents, depression was found in 128 people (53.3%). In the group of students with type D personalities, depression was significantly more frequent than in the group without type D personalities (p = 0.00). In participants with depression, TMD symptoms were more common, i.e., headaches, neck, and shoulder girdle pain, TMJ acoustic symptoms, increased masticatory muscle tension, teeth clenching, and teeth grinding. There was no significant difference between the incidence of depression and TMJ pain and jaw locking. There was a significant interaction between the occurrence of headaches and acoustic symptoms and the occurrence of depression. For headache and depression interactions, the OR was >1; based on the results, we may assume that a headache depends more on the occurrence of depression rather than it being a symptom of a TMJ disorder in people with type D personalities. Conclusion: type D personality and depression may contribute to the development of TMD symptoms.

Progressive Weakness and Rash

A 47-year-old man with hypercholesterolemia sought care for a 4-month history of progressive, proximal upper limb weakness and myalgia, followed by dysphagia, difficulty climbing stairs, and facial rash. Discontinuation of atorvastatin was of no benefit. Neurologic examination showed moderate weakness of the neck flexor muscles, shoulder girdle muscles, and finger extensors, and mild weakness of hip flexor and ankle dorsiflexor muscles. He had a heliotrope rash and Gottron sign. Serum testing showed an increased creatine kinase level. Needle electromyography showed myopathic changes with fibrillation potentials in proximal and axial muscles. Biopsy of the deltoid demonstrated a perifascicular pathologic process, including muscle fiber atrophy, and perivascular inflammatory exudate in the perimysium. Immunocytochemical studies showed patchy loss of intramuscular capillaries, some of which had complement (C5b9) deposition, and sarcoplasmic expression of myxovirus resistance protein A, mainly in the perifascicular regions. Immunologic testing was positive for autoantibodies to nuclear matrix protein 2 and negative for 3-hydroxy-3-methylglutaryl–coenzyme A reductase antibodies. Video swallow studies showed oropharyngeal dysphagia. Pulmonary function tests indicated mildly decreased maximal respiratory pressures but normal diffusing lung capacity for carbon monoxide. The findings were consistent with a diagnosis of dermatomyositis. The patient was started on oral prednisone and azathioprine, after checking for adequate thiopurine methyltransferase activity. Liver function tests and complete blood cell count with differential were assessed to monitor for potential azathioprine toxicity. Intravenous immunoglobulin was given. Follow-up examination revealed mild weakness of the shoulder girdle muscles after immunotherapy, and normal strength and creatine kinase value while on azathioprine monotherapy. Dermatomyositis is an idiopathic inflammatory myopathy. Idiopathic inflammatory myopathy is a group of autoimmune muscle diseases that includes dermatomyositis, polymyositis, inclusion body myositis, immune-mediated necrotizing myopathy, and overlap myositis, including antisynthetase syndrome.
