Neuroendocrine effects of a single bout of functional and core stabilization training in women with chronic nonspecific low back pain: A crossover study.

Exercise-induced hypoalgesia (EIH) is characterized as the pain reduction after an exercise session and it seems to be related to the release of plasma β-endorphin. In this sense, the core stabilization training (CT) has been suggested for patients with chronic nonspecific low back pain (CNSLBP), but it is unclear whether it induces EIH. Patients with CNSLBP have neuromotor dysfunctions that can affect the performance of functional tasks, thus, performing functional training (FT) could improve motor control and promote EIH, since functional training uses multi-joint exercises that aim to improve the functionality of actions performed in daily life. EIH is usually assessed using quantitative sensory tests (QST) such as conditioned pain modulation, pressure pain threshold, and temporal summation. Thus, the sum of parameters from quantitative sensory tests and plasma β-endorphin would make it possible to understand what the neuroendocrine effects of FT and CT session are. Our study compared the acute effect of CT and FT on the EIH and plasma β-endorphin release, and correlated plasma β-endorphin with quantitative sensory testing in patients with CNSLBP. Eighteen women performed two training sessions (CT and FT) with an interval of 48 h between sessions. EIH was assessed by QST and plasma β-endorphin levels. Results showed that only FT significantly increased plasma β-endorphin (FT p < 0.01; CT p = 0.45), which correlated with pain pressure threshold (PPT) and conditioned pain modulation (CPM). However, QST values were not different in women with CNSLBP after CT or FT protocols. Plasma β-endorphin correlated with PPT and CPM, however, the same did not occur with a temporal summation.

Case 305: Loeffler Endocarditis.

A 27-year-old man was admitted to the emergency department with fever and thoracic pain. In the previous 6 months, the patient lost a substantial amount of weight (12 kg). His family history was negative for cardiac disease. Electrocardiography revealed sinus rhythm and diffuse T-wave inversion. Two-dimensional echocardiography was performed and revealed normal left systolic function (ejection fraction, 60%). Laboratory tests showed elevated levels of high-sensitivity cardiac troponin (1.07 ng/mL; normal value, <0.015 ng/mL), high levels of C-reactive protein (16 mg/dL; normal range, 0-5 mg/dL), and leukocytosis with an eosinophilia level of 8710/μL (normal level, <400/μL). Parasitic and infectious diseases (, strongyloides, filariasis, cysticercosis, fasciola, trichinella, echinococcosis) were excluded based on blood and fecal test results. Corticosteroid therapy was started, and the patient was dismissed. A few days later, he was readmitted to the emergency department with a headache and suddenly blurred vision. Neurologic and ophthalmologic findings were normal, and MRI of the brain was performed. Cardiac MRI was performed 2 days later and revealed the following quantitative results: left ventricular end-diastolic volume (LVDV) of 165 mL (LVDV/body surface area [BSA], 89 mL/m; normal range, 64-100 mL/m), left ventricular end-systolic volume (LVSV) of 80 mL (LVSV/BSA, 43 mL/m; normal range, 17-39 mL/m), stroke volume (SV) of 85 mL (SV/BSA, 46 mL/m; normal range, 43-67 mL/m), and ejection fraction of 52% and right ventricular end-diastolic volume (RVDV) of 163 mL (RVDV/BSA, 88 mL/m; normal range, 63-111 mL/m), right ventricular end-systolic volume (RVSV) of 81 mL (RVSV/BSA, 44 mL/m; normal range, 32-92 mL/m), stroke volume (SV) of 82 mL (SV/BSA, 44 mL/m; normal range, 39-71 mL/m), and ejection fraction of 50%.

Transient regional osteoporosis of the ankle with shifting bone marrow edema pattern within the joint.

We describe a case of bone marrow edema (BME) shifting within one ankle joint in a 35-year-old – male patient. He presented with increasing pain and no history of trauma. Clinically no local swelling was found and laboratory findings and plain x-ray studies were normal. He did not improve on non-steroidal anti-inflammatory drugs for 2 weeks. A Gadolinium enhanced magnetic resonance imaging showed no evidence of synovitis, but BME was observed in the talus and transient regional osteoporosis was diagnosed. The patient was treated conservatively by protective partial weight bearing of the affected joint and he showed partial improvement after 6 months of daily treatment with Calcitonin Salmon nasal spray. A magnetic resonance imaging after 6 months showed that the BME had shifted anteriorly with complete resolution at the initial site. Transient regional osteoporosis is a rare self-limiting syndrome characterized by sudden onset of joint pain, functional limitations and spontaneous recovery, without preceding trauma. The condition may present as one episode affecting only one joint or recurrent episode that may affect multiple joints. BME between different compartments of the same joint can occur and has been reported only in a few case reports in the knee joint. The case is discussed and the literature is reviewed.

Mucormycosis, Diabetes and COVID-19 Pneumonia: Unleashing the Facts.

Background Mucormycosis (MM) is an angioinvasive locally destructive fungal infection. Before the coronavirus disease 2019 (COVID-19) pandemic, it was associated with diabetes (particularly diabetic ketoacidosis), immunosuppressive drugs and trauma. Among its various forms, cerebral invasion is considered to be highly fatal even if with long-term treatment. Treatment with injection amphotericin B (Amph-B) with early surgical interventions is highly efficacious. Liposomal preparation is considered to be superior in the context of fewer side effects. Methods We present a single-centre prospective study of 124 patients with MM in a tertiary care hospital. After the approval from the ethics committee, basic information was taken from all patients including all available past history about the COVID-19 infection and treatment. The studied outcomes were discharge, death and number of days of hospitalisation. Secondary objectives were to estimate the association of MM with known risk factors, to find the association of an outcome with various inflammatory markers, to determine adverse events with the use of injection Amph-B and posaconazole and to find the case fatality rate of MM. Results In our study, we observed that the number of patients with MM was double in the less than 60 years age group. However, mortality was 33.3% in the elderly as compared to 15.29% in patients less than 60 years of age. The majority of the patients (69.35%) were males, but no significant difference in mortality was seen between males and females. The case fatality rate was 20.97%. Ocular symptoms such as orbital swelling and pain were the common presenting symptoms. Almost all patients (93.54%) were diabetics. The non-diabetic group consisted of only 8 (6.4%) patients, and therefore, the comparison was not possible. A total of 20 (16%) out of 124 patients who had received high-dose steroids showed higher mortality (55%). Maximum patients (65.32%) had presented with MM following a past COVID-19 infection. However, a significant number of MM patients (20.96%) had a recent COVID infection and had higher mortality (57.69%) compared to their counterparts. The most common site of involvement in our study was the paranasal sinus (50%) and the outcome was the best in those patients whose disease was localised only to the sinuses, although among 14 (11.29%) patients with cerebral involvement, mortality was maximum (42.85%). Renal impairment and dyselectrolytemia were the most common adverse effects of Amph-B, and 46.42% of patients required surgical removal of the local part. Conclusion We saw that diabetes was a major contributory factor in the etiopathogenesis of MM. COVID-19 could also be a major causative factor by impairing the immune system; however, further studies at the molecular level are required to establish an association. The use of steroid cannot be the only independent risk factor, and other associated factors must be present. Treatment with antifungal and early surgical intervention had good outcomes. Treatment with conventional lyophilized Amph-B was equally efficacious as lipid-based solutions, but with more side effects. Hypokalemia and hypocalcemia were the most common electrolyte abnormalities associated with the use of injection Amph-B. Uncontrolled diabetes, the severity of the COVID-19 infection at presentation, acidosis, a high C-reactive protein level (above 100) and local brain involvement were associated with a poor outcome.

Atypical Scleroderma-like Chronic GVHD in a Liver Transplant Patient, Clinical and MRI Correlations.

Dear Editor, cutaneous chronic graft versus host disease (cGVHD) is a pathological process consisting of donor-derived T-cells aimed at the antigens of the recipient. It exhibits a large range of clinical presentations resembling morphea and deep sclerosis/fasciitis, all characterized by both inflammation and progressive dermal and hypodermic fibrosis (1). Although classic scleroderma-like lesions in cGVHD are nummular or irregular plaques and linear bundles associated with hypo- or hyperpigmentation (2), we report an atypical case with ulcerative presentation. No other case-reports of morphea-like or scleroderma-like cGVHD with an ulcerated appearance after liver transplantation (LT) and magnetic resonance imaging (MRI) correlation have been found in the literature. CASE REPORT Ten months after LT due to an end-stage cirrhosis associated with multifocal hepatocarcinoma (HCC), a 61-year-old man on immunosuppressive therapy with Tacrolimus (1 mg) and Everolimus (10 mg) presented to our clinic for a skin lesion in the right scapular region. We observed a flat ulcerated plaque with areas of sclerosis, minimal necrosis, and well-defined slightly erythematous margins (Figure 1, a). On palpation, the plaque had a hard consistency and was slightly painful. The skin lesion had been preceded by subjective discomfort with stinging sensation for seven months before its onset. Gradually lesion developed starting from a small, flat, oval purplish plaque associated with a progressive increase in pain. Patient denied dysphagia, retrosternal heartburn, Raynaud's phenomenon, arthralgia, and dyspnea. A previous MRI (Figure 2, a,b) showed subcutaneous and muscle edema. Blood tests showed abnormal liver function indexes due to extrahepatic cholestasis, while C-reactive protein, erythrocyte sedimentation rate, and leukocytes were within normal ranges. Self-reactive antibodies were negative. Histological examination (Figure 1, b) identified rare dyskeratotic keratinocytes and basal lymphocyte infiltrate, a dermal dense fibrosis with the disappearance of the skin appendages, and large fibrous septa in the adipose panniculus. It led to the diagnosis of scleroderma/morphea, based on the patient's clinical history. The diagnosis of graft versus host disease scleroderma-like post liver transplant was established. The lesion was treated by topical application of 0.05% clobetasol once a day. We did not use systemic immunosuppressive therapy in order to prevent HCC recurrence. The patient is currently in clinical follow-up to identify worsening or neoplastic degeneration. CASE DISCUSSION Cutaneous cGVHD often presents clinically as an ulcerative evolution in the context of fibrosis and diffuse skin atrophy (2), but very rarely initially appears as a well-delimited ulcerated plaque. Only few cases of ulcer have been found in literature, all in patients undergoing hematopoietic stem cell transplantation (HSCT), which is associated with the highest risk of developing GVHD, 20-50% (3,4), while LT has quite low incidence, at 0.5-2% (5). To our knowledge, this is the first case report of a scleroderma-like cGVHD lesion with ulcer appearance in LT. Our patient underwent two MRIs during post-transplant follow-up, which allowed us to evaluate the deep disease evolution. The T2-weighted MRI (Figure 2, c,d) performed approximately 1 year after transplantation, demonstrated fibrous septa in the subcutaneous fat and fascial thickening, with associated muscle hypotrophy and edema. The previous MRI, performed seven months after transplantation, already showed subcutaneous tissues and fascial edema, highlighting active inflammation. This evidence suggests that MRI could identify the lesion location before clinical manifestations, providing an opportunity to intervene promptly. To the best of our knowledge, this is the first reported case of cGVHD with atypical scleroderma-like presentation in a liver transplant patient whose clinical and MRI correlations have been traced. Our suggestions are supported by the results of other previous studies (6,7) evaluating MRI performance for assessing disease extent and activity, as well as therapeutic response in HSCT.
