Fibromyalgia(FM) is a complex pathology described as persistent hyperalgesia including somatic and mood dysfunctions, depression and anxiety. Although the etiology of FM is still unknown, a significant decrease in biogenic amines is a common characteristic in its pathogenesis. Here, our main objective was to investigate the role of dopamine D3/D2 receptor during the reserpine-induced pain in mice. Our results showed that pramipexole(PPX) – a dopaminergic D3/D2 receptor agonist – inhibited mechanical allodynia and thermal sensitivity induced by reserpine. Relevantly, PPX treatment decreased immobility time and increased the number of grooming in the forced swimming test and splash test, respectively. Animals that received PPX remained longer in the open arms than the reserpine group using elevated plusmaze apparatus. The repeated PPX administration, given daily for 4 days, significantly blocked the mechanical and thermal allodynia during FM model, similarly to pregabalin, although it failed to affect the reserpine-induced thermal nociception. Reserpine administration induced significant downregulation of dopamine concentration in the central nervous system, and repeated treatment with PPX restored dopamine levels in the frontal cortex and spinal cord tissues. Moreover, PPX treatment inhibited oxidants production such as DCFH(2′,7′-dichlorodihydrofluorescein) and nitrite, also decreased oxidative damage(carbonyl), and upregulated the activity of superoxide dismutase in the spinal cord. Together, our findings demonstrated the ability of dopamine D3/D2 receptor-preferring agonist in reducing pain and mood dysfunction allied to FM in mice. All experimental protocols were approved by the Universidade Federal de Santa Catarina(UFSC) Ethics Committee(approval No. 2572210218) on May 10, 2018.

We present a case of necrotizing pneumonia in an 87-year-old man without severe respiratory instability. Clinical suspicion arose due to the need for supplementary oxygen and persistent fever during treatment for community-acquired pneumonia. The diagnosis was confirmed by chest computed tomography. Although necrotizing pneumonia typically requires major surgical intervention upon diagnosis, we chose conservative management with antimicrobials and chest drainage alone. The patient experienced significant improvement and resolution of pneumonia with conservative management.

Pulmonary Tuberculosis Associated with Socioeconomic Vulnerability and Ineffective Support Network: Case Report

Tuberculosis is one of the 10 leading causes of death in the world. Its symptoms include fever, malaise, weakness, weight loss, chest pain, cough, expectoration, shortness of breath and sepsis, which is its most frequent complication. Due to these symptoms, many patients with tuberculosis require admission to the Intensive Care Unit, where they usually are placed on mechanical ventilation. Tuberculosis is more prevalent in the population in situations of social and economic vulnerability. The main factors that interfere with adherence to treatment and the prognosis of these patients are the patient’s support network and their socioeconomic status. We present the following report of a long-time smoker patient, with chronic kidney disease and previous treatment for tuberculosis, who was brought to the emergency room due to lowering of the sensorium, and was immediately placed on mechanical ventilation. The tests suggested sepsis with a respiratory focus, so a search for Alcohol-Acid-Resistant Bacillus was carried out, with a positive result. The patient was transferred to the Intensive Care Unit due to tachycardia and acute respiratory failure. The patient was a smoker with a high tobacco load, chronic kidney disease, in addition to precarious economic, educational and self-care conditions. This report shows that patients with tuberculosis and its complications can be stabilized through known pharmacological treatment. However, the most effective measure to interrupt the transmission of the disease remains the early diagnosis and the provision of adequate treatment, with guidelines aimed at the cessation of harmful habits, such as smoking.

Difficulties Faced by Physicians in the Diagnosis of Endometriosis in the Brazilian Public Health System

引用

Health 2023年第7期15卷 788-795页

Endometriosis is a clinical and recurrent condition characterized by the presence of functional endometrial tissue outside the uterine cavity and myometrium. It is estimated that 6% to 10% of women of reproductive age, 50% to 60% of adolescents and adults with pelvic pain, and up to 50% of women with infertility are pregnant from the condition. However, this proportion tends to be even greater due to the difficulty in diagnosing it: because it presents different symptoms, lack of information from health professionals, and a high-cost diagnostic test. Another aggravating factor is the average time from the onset of symptoms to the medical diagnosis, which even today ranges from five to ten years;this delay has consequences for disease progression, as it prevents early treatment, which is important for improving pain levels and physical and psychological well-being. Aware of these mishaps, it is therefore important to assess the difficulties faced by doctors in the diagnosis of endometriosis in the public health system, in Brazil, the Unified Health System (SUS). With this purpose, a cross sectional was carried out, developed in the virtual environment using traffic in Google forms, with the difficulties quantified in the Likert scale. Participating physicians pointed out a medium difficulty for patients with endometriosis to access the consultation (58%) and moderate difficulty (52%) to perform an ultrasound examination;also signaled great difficulty in performing magnetic resonance imaging (77%) and laparotomy (61%) in these patients. It is hoped that knowledge about the difficulties faced by physicians in the diagnosis of endometriosis in the SUS will give these physicians a voice and corroborate, even if minimally, so that there is more research that provokes the search for these difficulties, in order to improving the quality of life of these women.

Background: Skin reactions and musculoskeletal injuries caused by intramuscular injection are an increased risk for skin and soft tissue infections and may culminate in sepsis. Objective: To describe the history of an elderly patient who developed a lesion in her right arm after home administration of intramuscular iron injection in this arm and its outcome. Methods: This is a case report of a patient who participated in a study in an intensive care unit. Results: This study describes a 65-year-old patient with multiple comorbidities who was admitted to the hospital complaining of pain for two months and difficulty in moving her right shoulder associated with skin and soft tissue infections in her right arm after intramuscular iron administration by a relative for the treatment of multifactorial anemia and refractory melena. The patient worsened her general condition and was transferred to the intensive care unit. Despite the therapy instituted, the patient developed sepsis of cutaneous origin, multiple organ dysfunction, and death. Conclusions: The administration of intramuscular medication requires the participation of qualified professionals, such as nurses, mainly within the scope of the Brazilian public health system which commonly comprises patients in a context of vulnerability.
