The silent diabetic decompensation epidemic during the SARS-CoV2 pandemic - The role of primary care in early diagnosis and prevention of severe diabetic decompensation.

AIM/HYPOTHESIS: Efficiency in controlling chronic diseases, especially in the primary care setting, is associated with reduced rates of hospitalizations. Poorly controlled diabetes is associated with severe diabetic decompensation, such as diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS). It is hypothesized that, in addition to the SARS-CoV2 pandemic, there was a parallel increase in decompensation of previously controlled chronic diseases, such as diabetes. In this work, the impact of the SARS-CoV2 pandemic on hospitalizations for severe diabetic decompensation in a Portuguese hospital was assessed. METHODS: A retrospective study by hospital clinical file consultation was performed and a cohort of 177 patients admitted to a Portuguese hospital with a diagnosis of DKA or hyperosmolar hyperglycemic state HHS, excluding SARS-CoV2 infected patients, between 2019 and 2020 was analysed. RESULTS: In the population not infected by SARS-CoV2, statistically significant differences were found in the relative number of hospitalizations (5.59 vs 3.79 hospitalizations for DKA/HHS per 1000 patients not infected with SARS-CoV2, p = 0.0093) and lethality due to DKA/HHS (0941 vs 0337 deaths from DKA/HHS per 1000 patients not infected with SARS-CoV2, p = 0.0251). This increase in hospitalizations and lethality was accompanied by a statistically significant increase in newly type 2 diabetes diagnosis in DKA/HHS hospital admissions (p = 0.0156) and by a statistically significant increase in average age of patients (56.3 ± 22.4 vs 69.1 ± 17.6, p < 0.001). DISCUSSION AND CONCLUSIONS: These results show the empirical perspective that the consequences of the pandemic also had a considerable impact on the control of chronic diseases such as diabetes, with a higher percentage of hospitalizations due to severe decompensation, especially in the elderly population.

Non-alpine primary thyroid angiosarcoma

SUMMARY Thyroid angiosarcoma is an extremely rare malignancy, which occurs more frequently in the alpine region, likely associated with iodine deficiency and endemic goiter. This is an aggressive neoplasm that usually harbors a poor prognosis. We report the case of a 49-year-old Portuguese female patient presenting with a large nodule in the anterior neck region, with rapid growth and associated dysphonia. The neck ultrasound showed a hypoechogenic and heterogeneous thyroid nodule, with a larger axis of 44 mm. The fine needle aspiration cytology was not conclusive, and a biopsy of the lesion was performed. The result was suggestive of a mesenchymal tumor constituted by spindle cells and vascular clefts, showing positivity for endothelial markers and negativity for thyroglobulin, calcitonin and TTF1. The chest CT scan performed before surgery showed multiple pulmonary nodules suggestive of secondary lesions. The patient was submitted to total thyroidectomy and lymph node dissection in order to relieve compressive symptoms. A diagnosis of thyroid angiosarcoma was made after histologic examination of the surgical specimen. Despite undergoing multiple lines of palliative chemotherapy, the pulmonary lesions increased in size and number. The patient died due to respiratory failure 29 months after the diagnosis. Thyroid angiosarcoma is a rare malignancy, generally with poor prognosis. In our case, the patient presented with pulmonary metastases at diagnosis, which is a negative prognostic factor. Due to its rarity, data regarding management and treatment of this disease are scarce.

Parathyroid Carcinoma: A Rare Endocrine Malignancy.

BACKGROUND Parathyroid carcinoma (PC) is an extremely rare endocrine malignancy, with a reported increase in incidence in the past decade. PC generally presents in an indolent fashion, featuring nonspecific symptoms associated with hypercalcemia. CASE REPORT Case 1: A 30-year-old man was admitted for symptoms associated with hypercalcemia and elevated parathyroid hormone (PTH). Imaging examinations showed the presence of a cervical nodular lesion. The patient underwent surgery, and the pathological diagnosis was PC. Case 2: A 45-year-old man with a history of hypothyroidism was referred to our Endocrinology Department for a cervical nodular lesion. A fine-needle aspiration was performed, and the result was suggestive of papillary carcinoma. Blood testing showed only mild hypercalcemia and PTH elevation, with no associated symptoms. The patient underwent surgery, and the histological examination confirmed the diagnosis of PC. Case 3: A 38-year-old man presented with diffuse bone pain and muscle weakness, severe hypercalcemia, high levels of PTH, and a cervical mass. The patient underwent surgery. Diagnostic pathology confirmed the diagnosis of PC. Five years later, the patient presented with a cutaneous metastasis, followed 1 year later by pulmonary metastases. CONCLUSIONS Most PCs are slow-growing tumors. Some of these tumors are diagnosed in association with hereditary syndromes. A clear distinction between benign and malignant lesions is not always simple because there is a lack of specific clinical distinguishing features of malignant lesions. Currently, surgical resection is the preferred approach; however, owing to the rarity of this condition, there is a void of high-quality data.

Ovarian Leydig Cell Tumor: Cause of Virilization in a Postmenopausal Woman.

BACKGROUND Only 0.5% of all ovarian tumors are Leydig cell tumors and they are generally benign and unilateral. These androgen-secreting tumors lead to virilizing symptoms, most often in postmenopausal women. Because Leydig cell tumors are typically small, diagnosing them accurately can be challenging. CASE REPORT We report the case of a 77-year-old woman who was referred to our Endocrinology Clinic because of a 5-year history of hirsutism (Ferriman-Gallwey score of 11) with no discernible cause. The patient had high levels of serum testosterone and a normal level of dehydroepiandrosterone sulfate. Imaging, including transvaginal ultrasound and pelvic magnetic resonance, revealed a 16-mm uterine nodule, which was suspected to be a submucous leiomyoma, but no adrenal or ovarian lesions. Despite the lack of findings on imaging and because of the high suspicion for an androgen-secreting ovarian tumor, bilateral laparoscopic oophorectomy was performed. Histological examination of the specimen revealed a non-hilar Leydig cell tumor that measured 8 mm in its largest axis. After the surgery, the patient had significant clinical improvement and her laboratory test results normalized. Her sister had the same symptoms and laboratory findings at a similar age, which raised the suspicion of a possible familial genetic syndrome. No genetic testing was performed, however, because the patient's sister declined further diagnostic investigation. CONCLUSIONS Leydig cell tumors are rare, and even when they are small, they can cause symptoms related to androgen excess. As a result, diagnosing them often is challenging.

Metabolic control and therapeutic profile of patients with diabetes in Portuguese primary care (TEDDI CP).

AIM: To evaluate the metabolic control rate and to characterize the therapeutic profile of patients with Type 2 diabetes mellitus (DM2) from Portuguese primary care of National Health Service. METHODS: Cross-sectional multicentre study conducted in Portuguese primary health care units between July 2011 and May 2012. A national representative sample of 1528 DM2 patients was selected from 51 units, stratified by region. Socio-demographic, anthropometric, lifestyle, cardiometabolic risk factors, disease status, HbA1c levels and therapeutic information were collected. RESULTS: Patients' mean age was 65±10.7 years (50.4% males) and median duration of disease was 7 years: range (0-45 years). Almost 8% were smokers, 80.3% had hypertension, 61.6% hypercholesterolemia and almost 15% cardiovascular disease. Patients' health condition was classified with a score of 4 or 5 (excellent) for 60.6%. Median HbA1c was 6.6% (min-max: 4.2%-13.4%), 64.8% of the patients had HbA1c<7.0% and 49.2% HbA1c≤6.5%. Oral antidiabetics were used in 94.4% of the patients, antihypertensives in 80.6%, antidyslipidemics in 72.0%, antiplatelet agents in 50.6% and insulin in 8.3%. CONCLUSIONS: Metabolic control rate was good according to current guidelines. However, patients with higher HbA1c levels had longer time since diagnosis, worse current health condition, hypertriglyceridemia and were insulin-treated.
