Löfgren Syndrome: A Case Report and Treatment Challenge.

Sarcoidosis is an inflammatory and immune-mediated multisystemic disorder of unknown etiology, characterized by the presence of non-caseating granulomas, impacting various organs. This indolent condition manifests with numerous nonspecific symptoms and lacks a definitive diagnostic test, typically requiring histopathologic confirmation. However, a distinct and more readily diagnosable form of sarcoidosis does exist. The Löfgren syndrome (LöS) is characterized by the triad of erythema nodosum (EN), bilateral hilar lymphadenopathy, and symmetrical inflammatory arthralgias or arthritis. The simultaneous presence of these elements obviates the necessity for a biopsy. Predominantly affecting women in their second and third decades of life, this syndrome generally carries a favorable prognosis with spontaneous resolution or the requirement for a nonsteroidal anti-inflammatory drug (NSAID) alone. Despite its rarity, in particular cases, the treatment can be more challenging. This article presents a case study of LöS in a young woman, whose more aggressive disease course led to the need for steroidal therapy.

Asymptomatic Elevation of Pancreatic Enzymes: A Case of Gullo's Syndrome.

Benign pancreatic hyperenzymemia (BPH) or Gullo's syndrome is a benign condition consisting of an oscillating elevation of pancreatic enzymes without the identification of pancreatic disease. Its diagnosis is usually incidental and by excluding other conditions that occur with elevated pancreatic enzymes. To the best of our knowledge, there are no reports of this diagnosis to this day in Portugal. A 65-year-old female was referred to an internal medicine consultation for complaints of xerostomia, xerophthalmia, and xeroderma with one year of evolution. From the study carried out by the patient prior to the consultation, an incidental elevation of amylase stands out. The sicca symptoms were attributed to sertraline since, after excluding other causes, its discontinuation resolved the symptoms. Regarding the elevation of pancreatic enzymes, the patient underwent an extensive diagnostic study for clarification without identifying any condition. The serial measurement of amylase and lipase revealed an oscillating increase in pancreatic enzymes with temporary normalization. After one year of follow-up, the diagnosis of Gullo's syndrome was established. The identification of Gullo's syndrome is extremely important as it avoids carrying out unnecessary tests in the future and allows the patient to be reassured in the face of this benign alteration of pancreatic enzymes. A follow-up of at least one year is crucial since some pancreatic tumors course with an asymptomatic increase in pancreatic enzymes.

Primary Cardiac Tumor in the Left Atrium: A Diagnostic Challenge.

An elderly man presented to the emergency department with shortness of breath, peripheral edema, and significant weight loss. Blood tests revealed anemia and elevated inflammatory markers, and chest imaging showed a massive left pleural effusion. During hospitalization, he developed subacute cardiac tamponade, and pericardiocentesis was performed. Further imaging revealed a primary malignant cardiac tumor with extensive infiltration of the cardiac tissue, and biopsy was deemed impossible due to the tumor's location. The most likely diagnosis was angiosarcoma. The cardiac surgery team evaluated the case and considered it inoperable due to the tumor's extensive infiltration. The patient is currently under the regular care of a palliative care team. This case underscores the difficulties of diagnosing primary cardiac tumors, particularly in elderly patients with comorbidities. Despite advances in imaging and surgical techniques, the prognosis for malignant cardiac tumors remains poor.

Rare manifestations of refractory extrapulmonary sarcoidosis.

Sarcoidosis is a multisystemic disease, characterised by histopathologic presence of non-necrotising granulomas, primarily affecting the lungs (>90%). We present three cases predominantly characterised by uncommon extrapulmonary manifestations of sarcoidosis, where only one had pulmonary involvement. We describe three female patients, between the second and third decades of life, whose sarcoidosis was a diagnostic challenge due to their atypical extrapulmonary manifestations, from which we highlight: livedo reticularis and painful subcutaneous nodules with uncommon localisation, size and histology, being the first reported case of extensive subcutaneous nodules triggered by intramuscular penicillin; extensive symptomatic and refractory osseous involvement; and dispersed erythema nodosum affecting the entire body surface. All three patients required third-line treatment (antitumour necrosis factor agents) to achieve significant clinical and imagiological improvement. Through this case series, we highlight the importance of considering the rare and atypical presentations of sarcoidosis to avoid diagnostic delays and serious repercussions on the patient's prognosis.

Morvan's Syndrome: The Importance of Knowing Different Risk-Associated Phenotypes and Antibodies in Identifying the Correct Underlying Tumor.

Paraneoplastic neurologic syndromes (PNS) are neurologic disorders that can affect any part of the nervous system, occur in association with cancer, and have an immune-mediated mechanism that produces direct damage to the neural tissue. Neurological symptoms frequently precede, in months to years, the symptoms directly attributed to the primary tumor, requiring a high clinical suspicion for adequate investigation. We report the case of a man in his early 80s admitted for an altered level of consciousness, alternating between periods with stupor and drowsiness, short-term waking states and psychomotor agitation, respiratory failure and dysautonomia, resembling a Morvan's syndrome. Anti-leucine-rich glioma-inactivated 1 and anti-contactin-associated protein-like 2 antibodies were both positive and, after exclusion of infectious and autoimmune systemic causes, the possibility of PNS was raised. Screening for the primary tumor was pursued, and an 18F-fluorodeoxyglucose (18F-FDG)/PET showed only an intensely hypermetabolic, apparent parietal thickening of the lower rectum. Due to the frequent association of Morvan's syndrome to thymoma, a review of the CT of the thorax images was requested and a mediastinal image with features of thymoma was identified. PNS treatment and prognosis depend on finding and treating the underlying tumor, with benefits in both resolution of neurological symptoms and in the prognosis of the underlying tumor itself. Therefore, clinicians should be aware of this frequent but underdiagnosed and underreported condition, in order to improve the chances of better outcomes.

Lymphocyte-Depleted Hodgkin's Lymphoma in Coeliac Disease: A Diagnostic Challenge During the COVID-19 Pandemic.

A 51-year-old woman presented with constitutional symptoms, polydipsia, early satiety, nausea, vomiting, and a pruritic vesicular rash. On physical examination, she was febrile, had low peripheral oxygen saturation in room air (91%), hepatomegaly, lower limb edema, and palpable cervical adenopathies. She was hospitalized for diagnostic investigations and treatment. An autoimmune panel was requested which was positive for anti-parietal gastric cell, anti-endomysial, and anti-tissue transglutaminase antibodies, raising the suspicion for coeliac disease (CD). Gastric and duodenal biopsies were not diagnostic for CD, which was compatible with necrolytic migratory erythema similar to the vesicular rash biopsy. Thoracic-abdomino-pelvic computed tomography scan and fludeoxyglucose F18-positron emission tomography identified supra- and infra-diaphragmatic hypermetabolic adenopathies, with hypermetabolic activity in the lungs, suggestive of pulmonary lymphomatous involvement. Fine-needle aspiration of one supraclavicular adenopathy was performed but was not enough for histological diagnosis. The patient's respiratory insufficiency worsened and she died on day 63 of hospitalization. The final diagnosis was achieved on an anatomopathological autopsy that showed lymphocyte-depleted Hodgkin's lymphoma. The association of CD with other lymphomas besides enteropathy-type T-cell lymphoma is not clear. There is no clear relationship between CD and lymphocyte-depleted Hodgkin's lymphoma, which is the rarest subtype of classic Hodgkin's lymphoma and, by itself, has a very poor prognosis. This case highlights the challenge in diagnosis and significant delay due to isolation associated with coronavirus disease 2019 infection.

The impact of nutrition and lifestyle modification on health.

The main recommendations from public health entities include healthy diets and physical activity as the main lifestyle factors impacting the development of chronic diseases such as cardiovascular and metabolic diseases, cancer, and even neurological diseases. Randomized clinical trials have been designed to demonstrate those lifestyle modifications can change the pattern of chronic diseases development and progression. Among these, nutrition is one of the most impacting factors. Therefore, nutrition and diets were also included in different randomized clinical trials, and most of them showed a favorable impact of nutrition modification on the participant's health. Nevertheless, study designs were considerably different, and future studies are needed to support nutrition modifications further. The choice of a healthy considered diet, like the Mediterranean diet, was shown to impact chronic diseases, cardiovascular risk, and adult life expectancy mainly due to its anti-inflammatory and antioxidant properties. Furthermore, a high intake of fibers, fruits, and vegetables together with a low intake of fat and energy-dense, processed foods contribute to an inflammation reduction and a more robust immune system leading. Besides these well-known properties, all lifestyle modifications must be personalized according to the availability of foods, geographic localizations, and the healthy status of the patient.

Protein Mannosylation as a Diagnostic and Prognostic Biomarker of Lupus Nephritis: An Unusual Glycan Neoepitope in Systemic Lupus Erythematosus.

OBJECTIVE: Changes in protein glycosylation are a hallmark of immune-mediated diseases. Glycans are master regulators of the inflammatory response and are important molecules in self-nonself discrimination. This study was undertaken to investigate whether lupus nephritis (LN) exhibits altered cellular glycosylation to identify a unique glycosignature that characterizes LN pathogenesis. METHODS: A comprehensive tissue glycomics characterization was performed in kidney specimens from patients with systemic lupus erythematosus and biopsy-proven LN. A combination of advanced tissue mass spectrometry, in situ glyco-characterization, and ex vivo glycophenotyping was performed to structurally map the repertoire of N-glycans in LN tissue samples. RESULTS: LN exhibited a unique glycan signature characterized by increased abundance and spatial distribution of unusual mannose-enriched glycans that are typically found in lower microorganisms. This glycosignature was specific for LN, as it was not observed in other kidney diseases. Exposure of mannosylated glycans in LN was shown to occur at the cell surface of kidney cells, promoting increased recognition by specific glycan-recognizing receptors expressed by immune cells. This abnormal glycosignature of LN was shown to be due to a deficient complex N-glycosylation pathway and a proficient O-mannosylation pathway. Moreover, mannosylation levels detected in kidney biopsy samples from patients with LN at the time of diagnosis were demonstrated to predict the development of chronic kidney disease (CKD) with 93% specificity. CONCLUSION: Cellular mannosylation is a marker of LN, predicting the development of CKD, and thus representing a potential glycobiomarker to be included in the diagnostic and prognostic algorithm of LN.

Hypoglycemic episodes in hospitalized people with diabetes in Portugal: the HIPOS-WARD study.

BACKGROUND: We intended to estimate the proportion hypoglycemic/hyperglycemic emergency episodes in treated diabetes mellitus (DM) patients admitted to a hospital ward, and calculate the prevalence of risk factors for hypoglycemia and diabetic complications. METHODS: In this cross-sectional, multicentered study, the observational data was collected by physicians from patient's hospitalization to discharge/death. Statistical tests were 2-tailed considering 5% significance level. RESULTS: There were 646 ward admissions due to hyperglycemic emergencies and 176 hypoglycemic episodes with a ratio hypoglycemia/hyperglycemia 0.27 for all DM patients. In T2DM patients the ratio was 0.38. These were mainly female (55.1%), functionally dependent (61.4%) and retired/disabled (73.1%). Median age was 75 years and median duration of disease 11 years. Half the patients were on insulin-based therapy and 30.1% on secretagogue-based therapy. Approximately 57% of patients needed occasional/full assistance to manage the disease. The most frequent risk factor for hypoglycemia was polypharmacy (85.0%). Hypoglycemia in the 12 months before admission was higher in insulin-based therapy patients (66.1%; p = 0.001). CONCLUSIONS: Hyperglycemic emergencies are the most frequent cause of hospitalization in Portugal, although severe hypoglycemic events represent a health and social problem in elderly/frail patients. There is still the need to optimize therapy in terms of the potential for hypoglycemia in this patient group and a review of anti-hyperglycemic agents to add on to insulin.

[Peer Assisted Learning: A Pedagogical Alternative of Teaching Skills to Medical Students]. / Aprendizagem Assistida por Pares: Uma Alternativa Pedagógica no Ensino de Competências a Estudantes de Medicina.

INTRODUCTION: Technical skills training is fundamental for clinical practice although poorly emphasised in undergraduate medical curricula. In these circumstances, Peer Assisted Learning methodology has emerged as a valid alternative to overcome this insufficiency. The purpose of this study is to evaluate the impact on students of a Peer Assisted Learning program in basic surgical skills, regarding technical competences and knowledge improvement. MATERIAL AND METHODS: A total of 104 randomly selected third year medical students participated in a workshop delivered by fifth year students. From that total, 34 students were assessed before and after the workshop, using the Objective Structured Assessment of Technical Skills instrument, that consists of a global rating scale and a procedure-specific checklist. Sixth year students (control group) were also assessed in their performance without participating in the workshop. Before workshop versus after workshop Objective Structured Assessment of Technical Skills results were compared using Wilcoxon and McNemar tests. After workshop versus control group Objective Structured Assessment of Technical Skills results were compared using Mann-Whitney, qui-squared test and Fisher's exact test. RESULTS: For the global rating scale, students obtained an after the workshop score (29.5) that was significantly higher than the before the workshop score (15.5; p-value < 0.001), but no significant differences were found between after the workshop and control group scores (p-value = 0.167). For the procedure-specific checklist, 3rd year students had a substantial positive evolution in all parameters and obtained higher rates of correct achievements compared to the control group. DISCUSSION: The final outcomes demonstrated a significant qualitative and quantitative improvement of knowledge and technical skills, which is in accordance with other literature. CONCLUSION: This Peer Assisted Learning program revealed promising results concerning improvement of surgical skills in medical students, with little staff faculty contribution and extension to a much broader number of students.

Development of a Healthy Lifestyle Assessment Toolkit for the General Public.

The prevalence of age-related non-communicable chronic diseases has increased worldwide, being the leading causes of morbidity and death in many world regions, including in Europe. Innovative models and strategies focused on preventive care, including early identification of risk factors underlying disease onset and progression, and proper modification of lifestyle habits and behaviors, might contribute to promote quality of life, healthy living and active aging. Healthy Lifestyle Innovative Quarters for Cities and Citizens (HeaLIQs4cities) is an EIT Health-funded project aiming to engage, empower and educate citizens toward healthy lifestyles. One of the major objectives of this project was to develop a toolkit for a rapid and informal assessment of healthy lifestyles, to be used at different levels of care pathways, including in informal public environments. In this paper, we describe the methodology underlying the development of the toolkit, which resulted from the collaboration of an interdisciplinary focus group of academic experts, from medicine, sport sciences, psychology, health economics, and innovative technologies applied to health. The following eight components were included in the toolkit: (1) anthropometric assessment and cardiometabolic parameters; (2) physical activity and exercise; (3) well-being, social cohesion, and functional independence; (4) nutrition; (5) mental health; (6) smoking, drinking, and use of illicit substances; (7) sleep habits and quality; and (8) health and disease. A traffic light rating system indicating the risk score was used (low: green; moderate: yellow; and relevant: orange) for each of the 8 components, together with recommendations for the toolkit users. After completing the reduced version of the toolkit, individuals showing moderate or relevant risk in one or more of the 8 dimensions, were invited to participate in a more detailed assessment (toolkit long version), based on deeper and scientifically validated tools. The toolkit was incorporated in eVida, a web-based platform that focuses on delivering services to personalized health and well-being. The validation of the current toolkit has been applied in wide-ranging public events in three different European Regions. Large scale deployment of the toolkit is expected to profit from the Reference Site Collaborative Network of the European Innovation Partnership on Active and Healthy Aging (EIP on AHA).

Early manifestation of myocardial involvement in systemic sclerosis.

INTRODUCTION: Systemic sclerosis (SSc) is a systemic autoimmune disease involving multiple organs. We present a rare case of SSc in which clinical manifestations of cardiac fibrosis occurred early in the disease course. CASE REPORT: We report the case of a 40-year-old Caucasian man, previously diagnosed with SSc, who presented with decompensated heart failure. Transthoracic echocardiography was remarkable for severe right ventricular systolic dysfunction, abnormal ventricular septal motion, severe functional tricuspid regurgitation and normal pulmonary artery systolic pressure. Left ventricular ejection fraction was 45%. Right heart catheterization revealed no signs of pulmonary hypertension. Cardiac magnetic resonance (CMR) showed diffuse myocardial infiltration, later confirmed as myocardial fibrosis by endomyocardial biopsy. CONCLUSIONS: Myocardial fibrosis is an important cause of early heart failure in SSc patients and is associated with poor prognosis. Echocardiography and CMR help establish the diagnosis and enable an appropriate therapeutic strategy to be developed in such cases.

Adherence to a Mediterranean diet, lifestyle and age-related macular degeneration: the Coimbra Eye Study - report 3.

PURPOSE: To characterize the lifestyle and nutritional risk profile associated with the Mediterranean diet in a Portuguese population with and without age-related macular degeneration (AMD). METHODS: Nested case-control study (n = 883) within the Coimbra Eye Study, including 434 subjects with AMD and 449 age- and sex-matched subjects without AMD. All enrolled subjects underwent a full risk assessment, including lifestyle-related risk factors and a thorough food frequency questionnaire. This allowed us to build an adherence score to the Mediterranean diet (mediSCORE, range 0-9) constructed from individual food intakes. Food intake was also further analysed by conversion to micronutrient consumption. RESULTS: Our results suggest that physical activity has a protective role in AMD [p = 0.018 after multivariate adjustment, OR: 0.69 (0.51-0.93)]. High (mediSCORE ≥6) was also found to be protective [p = 0.041, OR: 0.62 (95% CI: 0.38-0.97)]. Food group analysis unveiled a specific protective role for increased fruits consumption (p = 0.029). Finally, micronutrient analysis revealed a protective role associated with increased consumption of caffeine, fibres, beta-carotene, vitamin C and vitamin E (p < 0.05). CONCLUSION: High mediSCORE appears to confer protection against the development of AMD in a Mediterranean population. This effect is driven by increased consumption of fruits and some antioxidant micronutrients, which emerged as statistically significant protective factors. Further studies are required to establish dietary recommendations with clinical application.

Lymphedema secondary to limited cutaneous systemic sclerosis.

Systemic sclerosis (SSc) is an autoimmune connective tissue disease characterised by vascular abnormalities, immune system activation and fibrosis. Lymphatic involvement in SSc was described more recently and starts in early stages. This report describes a 46-year-old patient who developed over the last 2 years asymmetric lymphedema in lower extremities. Compromise in lymphatic drainage was confirmed by lymphoscintigraphy. She also presented Raynaud's phenomenon, a scleroderma pattern in nailfold capillaroscopy, cutaneous thickening and anticentromere antibodies, which together resulted in a new diagnosis of limited cutaneous SSc. Treatment with methotrexate, prednisolone and lymphatic drainage resulted in lymphedema improvement. To our knowledge, this is the first case of grade 2 lymphedema in the setting of anticentromere-positive limited cutaneous SSc. We highlight the importance of considering rheumatic diseases in the differential diagnosis of lymphedema.

Orthorexia nervosa in a sample of Portuguese fitness participants.

PURPOSE: Orthorexia Nervosa (ON) is described as an obsessive behaviour motivated by great concern for following a healthy diet. Although it was first described in 1997, ON remains inconspicuous and poorly characterized in the literature. The aims of this study were to evaluate the prevalence of ON in a sample of ambulatory individuals and to investigate their common characteristics, attempting to better characterize this entity. METHODS: A non-random sample of 193 adult gym members answered a questionnaire based on a Portuguese version of ORTO-15, supplemented with additional questions. Possible associations between the different variables and pathological scores on ORTO-15 were analysed using logistic regression models. RESULTS: ON behaviour was documented in 51.8% of the sample, mean age 30.96 years (± 1.03 years), and this condition tended to be correlated with younger ages. Physical appearance and frequent exercising were also associated with ON, while no correlation between orthorexic tendencies and both gender and educational field was found. Furthermore, consumption of special food, dissatisfaction with physical appearance and frequent exercising could predict the presence of ON in the sample. CONCLUSIONS: Despite the use of a convenience sample, results place us in a different perspective, considering the idea that orthorexic individuals are exclusively concerned about pursuing a pure diet. The presence of ON was associated with other non-dietary behaviours allied to a healthy lifestyle and aesthetic concerns. LEVEL OF EVIDENCE: Level V: Descriptive study.

Adherence to a Mediterranean diet and its association with age-related macular degeneration. The Coimbra Eye Study-Report 4.

OBJECTIVES: This study aimed to characterize the association of lifestyle and nutritional risk profiles with age-related macular degeneration (AMD) in two subpopulations with differing AMD prevalence. METHODS: This case-control study (n = 1992) included 768 patients with AMD and 1224 age- and sex-matched participants without AMD with a single visit at a primary health care unit. Enrolled participants completed a validated lifestyle and food frequency questionnaire. A score to measure adherence to the Mediterranean diet (mediSCORE; Range, 0-9) was constructed from individual food intakes, which were further analyzed by conversion to nutrient consumption. RESULTS: Higher adherence to the Mediterranean diet (mediSCORE ≥6) was significantly associated with no AMD (odds ratio [OR] = 0.73; P = 0.009). The subpopulation with lower AMD prevalence presented significantly higher adherence to the Mediterranean diet in relation to all individual food groups that comprised the mediSCORE (P < 0.014) with the exception of cereals. Food group analysis showed significant associations between the increased consumption of vegetables (OR = 0.63; P < 0.001) and fruit and nuts (OR = 0.78; P = 0.010) with no AMD. Nutrient analysis revealed that an increased ingestion of water, fibers, total fat, monounsaturated and polyunsaturated fatty acids, linoleic acid, vitamins A and C, carotene, alpha-tocopherol, folate, magnesium, iron, and zinc were significantly associated with no AMD (P < 0.0013). Finally, regular physical activity was associated with no AMD (P = 0.003). CONCLUSIONS: High adherence to a Mediterranean diet and regular physical activity seem to be protective factors for AMD in a Portuguese population. The effect of the diet is likely driven by the increased consumption of vegetables, fruits, and nuts.

When a Goitre is a Thyroid Lymphoma.

Primary thyroid lymphoma is a rare cause of both thyroid malignancy and extra-nodal lymphoma. It typically presents as a rapidly enlarging goitre with compressive symptoms. Histological analysis of a biopsy specimen is necessary to confirm the diagnosis. Awareness of this disease is important for early diagnosis and appropriate treatment. A 55-year-old man was admitted due to a 3-month history of cervical enlargement, facial and periorbital oedema and dyspnoea, apparently due to a superior vena cava syndrome. However, cervical ultrasound showed asymmetrical thyroid enlargement, lobulated contours and a hypoechogenic texture. A neck CT scan showed calibre reduction of the superior vena cava. The diagnosis of primary thyroid lymphoma was confirmed by open biopsy of the thyroid gland. The patient started treatment with rituximab with clinical improvement. LEARNING POINTS: Primary thyroid lymphoma is rare, accounting for less than 5% of thyroid malignancies and less than 2% of extra-nodal lymphomas, but should be suspected in the presence of a rapidly enlarging goitre.Fine needle aspiration biopsy is the initial technique of choice, but core needle biopsy or open surgical biopsy may be necessary to establish the diagnosis.Treatment and prognosis are dependent on accurate histological classification, with the disease generally treated successfully with chemotherapy.

Pain improvement in Camurati-Engelmann disease after anti-TNFα therapy.

Camurati-Engelmann disease (CED) is a rare disorder included in the group of craniotubular hyperostosis diseases. Corticosteroids are used for pain management in CED, but in refractory or corticosteroid-non-tolerant patients, pain management is limited. We report the case of a woman with CED diagnosed in early infancy whose initial complaints included persistent bone pain associated with progressive functional disability. She was treated with steroids but over time became dependent on higher doses with only mild pain relief. In her third decade, she was diagnosed with ulcerative colitis (UC) and was treated with mesalazine, azathioprine and prednisolone. Due to recurrent exacerbations of UC, treatment was changed to infliximab, an antitumour necrosis factor-alpha (TNFα). Remission of UC was achieved and CED-associated pain also improved with infliximab. This is the first report showing a possible role of anti-TNFα in pain management in CED with unsatisfactory response to steroids.

Fascioliasis-a rare cause of hepatic nodules.

Fascioliasis is a zoonotic disease that can sometimes affect humans. It presents with non-specific signs and symptoms which makes it difficult to establish an early definitive diagnosis. This can be particularly true in non-endemic countries where a high degree of suspicion is needed to make the diagnosis. Another confounding factor is that many of the initial complains and findings are very similar to those of malignancy. We report a case of an otherwise healthy 47 year-old male presenting with abdominal pain, night-time sweating, anorexia, weight loss and loose stools that had several hepatic nodules visible in the abdominal CT scan. Although the initial hypothesis was hepatic malignancy or liver metastasis of unknown primary neoplasm, the workup performed led us to the correct diagnosis. He was treated successfully for hepatic fascioliasis, with a full recovery.
