Cardiac findings in pediatric patients with spinal muscular atrophy types 2 and 3.

BACKGROUND: It is unclear whether the heart is affected in pediatric patients with milder forms of spinal muscular atrophy (SMA). Therefore, we aimed to determine the presence of any cardiac abnormalities in these patients. METHODS: We conducted a cross-sectional study of children and adolescents with SMA types 2 and 3 between July 2018 and July 2019. All patients underwent a comprehensive cardiac evaluation, including history-taking, physical examination, electrocardiography, echocardiography, measurement of cardiac biomarkers (cardiac troponin T [cTnT] and N-terminal pro-brain natriuretic peptide [NT-proBNP]), and 24-hour Holter monitoring. RESULTS: In total, 42 patients were enrolled (27 and 15 with SMA type 2 and 3, respectively). No patient had structural heart disease, except for one with mitral valve prolapse. None had signs of ventricular dysfunction on echocardiography. Both cTnT and NT-proBNP levels were normal in all patients. Electrocardiography showed sinus tachycardia in seven patients (16.7%), and prolonged P-R interval in one (2.4%). Holter monitoring detected benign ventricular arrhythmias in two patients (4.8%), and rare supraventricular premature beats in one. The mean 24-hour heart rate was elevated in six patients (14.3%), whereas both the minimum 24-hour heart rate and the maximum R-R interval were increased in 23 (54.8%). DISCUSSION: The prevalence of cardiac disease in pediatric patients with SMA types 2 and 3 is low; however, these patients may have increased resting heart rates. A complete cardiac history and physical examination are a useful screen. Additional cardiac investigations may be performed as needed.

Effects of Spinal Decompression and Segmental Spinal Instrumentation on Lower Limb Functionality in Patients with Spinal Osteoarthritis.

Spinal osteoarthritis, a degenerative condition of the spine, significantly impairs quality of life, causing pain, stiffness, and limited mobility. Treatment primarily aims to improve functionality and quality of life. This study investigated the effects of lower back surgery (e.g., spinal decompression with vertebra stabilization) on upper-limb maximum strength, lower limb functionality, and quality of life in osteoarthritis patients. A total of 16 patients (♀ = 10 and ♂ = 6) patients from the orthopedic clinic who were diagnosed with osteoarthritis based on MRI and clinical symptoms underwent the surgery. Their handgrip strength, lower limb functionality (6 min walk test), and quality of life (Flanagan quality of life scale) were assessed before and after the surgery. A repeated measures ANOVA was conducted to assess differences in these metrics pre- and post-surgery across the entire patient cohort, as well as within gender-specific subgroups. A large positive effect was seen in the 6 min walk (p = 0.02, d = -0.83) test but not in the handgrip test or quality of life. However, female patients showed a trend towards better quality of life. The results of this study provide evidence for the effectiveness of surgery in the treatment of spinal osteoarthritis and underscore the need for personalized treatment approaches in the treatment of spinal osteoarthritis.

Coexisting diseases modifying each other's presentation - lack of growth failure in Turner syndrome due to the associated pituitary gigantism.

Introduction: Turner syndrome presents with one of the most frequent chromosomal aberrations in female, typically presented with growth retardation, ovarian insufficiency, facial dysmorphism, and numerous other somatic stigmata. Gigantism is an extremely rare condition resulting from an excessive growth hormone (GH) secretion that occurs during childhood before the fusion of epiphyseal growth plates. The major clinical feature of gigantism is growth acceleration, although these patients also suffer from hypogonadism and soft tissue hypertrophy. Case report: We presented a girl with mosaic Turner syndrome, delayed puberty and normal linear growth for the sex and age, due to the simultaneous GH hypersecretion by pituitary tumor. In the presented case all the typical phenotypic stigmata related to Turner syndrome were missing. Due to excessive pituitary GH secretion during the period while the epiphyseal growth plates of the long bones are still open, characteristic stagnation in longitudinal growth has not been demonstrated. The patient presented with delayed puberty and primary amenorrhea along with a sudden appearance of clinical signs of hypersomatotropinism, which were the reasons for seeking medical help at the age of 16. Conclusion: Physical examination of children presenting with delayed puberty but without growth arrest must include an overall hormonal and genetic testing even in the cases when typical clinical presentations of genetic disorder are absent. To the best of our knowledge, this is the first reported case of simultaneous presence of Turner syndrome and gigantism in the literature.

Unrecognised adrenergic symptoms and the delayed diagnosis of urinary bladder paraganglioma.

INTRODUCTION: Paraganglioma is a rare neuroendocrine neoplasm that may arise from the extra-adrenal autonomic paraganglia. Urinary bladder paraganglioma is typically presented as repeated episodes of palpitations, headache or blood pressure rise immediately after micturition. Management of these tumors includes radical surgical treatment with preoperative antihypertensive preparation, and a life-long follow-up. CASE REPORT: We presented a middle-age female patient with functional urinary bladder paraganglioma, with a 3-year history of repeated episodes of abdominal pain, dysuria and hematuria. After obtaining more precise anamnestic data, the patient reported occasional simultaneous presence of mild adrenergic symptoms, that did not cause any particular attention at first. Morphological and biohumoral examinations suggested paraganglioma of the urinary bladder. Open partial cystectomy was performed, detecting a submucosal mass, while immunohistochemical analysis confirmed the presence of chromaffin tissue. Clinical manifestations, diagnostic approach, management and histopathological findings of urinary bladder paraganglioma are discussed. CONCLUSION: Since the prognosis with localized paraganglioma is good, we underlined the importance of a well-timed, accurate and detailed medical history in all the patients with even mild, inexplicable micturition-provoked adrenergic symptomatology.
