A case study of eruptive fissure opening at Mount Etna
AbstractThis paper deals with the online offset detection in GPS time series recorded in volcanic areas. The interest for this problem lies in the fact that an offset can indicate the opening of eruptive fissures. A Change Point Detection algorithm is applied to carry out, in an online framework, the offset detection. Experimental results show that the algorithm is able to recognize the offset generated by the Mount Etna eruption, occurred on December 24, 2018, with a delay of about 4 samples, corresponding to 40 min, compared to the best offline detection. Furthermore, analysis of the trade-off between success and false alarms is carried out and discussed
The unusual association of Graves' disease, chronic spontaneous urticaria, and premature ovarian failure: report of a case and HLA haplotype characterization
Chronic spontaneous urticaria (CSU), defined as the occurrence of spontaneous wheals for more than six weeks, has been associated with autoimmune diseases. Herein, we report the unusual association of CSU, Graves' disease, and premature ovarian failure. Human leukocyte antigen (HLA) studies were performed. A 36-year-old woman presented symptoms and signs of hyperthyroidism for three months. In the same period, the patient complained of widespread urticarial wheals, intensely itchy, and poorly responsive to therapy with antihistaminic agents. Hyperthyroidism was confirmed biochemically, and treatment with methimazole was started. As hyperthyroidism improved, a marked improvement in her urticaria was also observed. However, the patient continued to complain of amenorrhea. Endocrine evaluation, at the age 38, was consistent with premature ovarian failure. This is the first report of coexistence of GD, CSU, and POF. The genetic background of such unusual association is a specific combination of HLA
Ovarian hyperthecosis coexisting with an incidental adrenal lesion: challenges in the diagnostic approach
Ovarian hyperthecosis is the most common cause of hyperandrogenism in women during postmenopausal age. However, its diagnosis is frequently challenging, since several causes must be ruled out, involving both adrenal glands and ovaries. Herein we describe the case of a 62 years old woman addressed to our Unit after the casual detection of an adrenal mass, compatible with an adenoma. Biochemical evaluation revealed gonadotropins in menopausal range, high testosterone and androstenedione, while the patient had been complaining of androgenetic alopecia and hirsutism for some years. Ultrasound imaging revealed only a small increase in ovarian volume, in relationship to the patient’s age. A GnRHa test was performed, demonstrating gonadotropins suppression and testosterone normalization, thus confirming the suspect of ovarian hyperthecosis. The administration of these agonists, together with the slow progression of symptoms over years, play a fundamental role into excluding an androgen-secreting neoplasia, also limiting the use of ovarian veins catheterization as second line test. Besides, they represent a valid therapeutical option, especially when surgery is contraindicated (or cannot be performed)
An extremely rare association of TSH-secreting pituitary adenoma, metastatic neuroendocrine tumor and Cushing’s syndrome in a patient with MEN-1 gene mutation
Multiple endocrine neoplasia (MEN)-1 syndrome is a rare disorder, due to the loss of function of the tumor suppressor menin. It consists of the association of two or more endocrine tumors, often presenting in a familial setting, being inherited in an autosomal dominant fashion. The most frequent manifestations of MEN-1 syndrome are primary hyperparathyroidism, followed by pituitary adenomas (mainly prolactinomas) and gastrointestinal neuroendocrine tumors, but several other associated conditions have been reported. Herein we describe the case of a male patient, affected by sporadic MEN-1, diagnosed with primary hyperparathyroidism, TSH-secreting pituitary adenoma and bilateral adrenal hyperplasia causing Cushing’s syndrome, due to a de novo MEN-1 gene mutation. The patient has been successfully treated with first generation somatostatin analog Octreotide LAR (30 mg every 28 days) -with stabilization of the known neuroendocrine lesions and shrinkage of the pituitary adenoma- and with bilateral adrenalectomy. The patient is still regularly followed-up at our Endocrine Unit, and his clinical conditions are stable
Global incidence and prevalence of differentiated thyroid cancer in childhood: systematic review and meta-analysis
ObjectiveDifferentiated thyroid cancer (DTC) is rare in childhood and adolescence although it represents the most frequent endocrine malignancy in this population. DTC includes both papillary thyroid carcinoma (PTC) and follicular thyroid carcinoma (FTC). Most pediatric DTCs are PTCs, while FTCs are rare. To date, no systematic reviews on the global epidemiology of pediatric and adolescent DTC have been published. This systematic review and meta-analysis aims to estimate the overall incidence and prevalence of DTCs in patients aged 0–19 years.MethodsThe systematic research was conducted from January 2000 to December 2021 through MEDLINE via PubMed, Cochrane Library, and Embase databases. Two separate meta-analyses were performed for PTC and FTC.ResultsAfter the selection phase, a total of 15 studies (3,332 screened) met the inclusion criteria and are reported in the present systematic review. Five studies were conducted in Europe, five in North America, two in South America, one in Asia, one reported data for 49 countries and territories across the five continents, and one from both the USA and Africa. Most of the studies (n = 14) reported data obtained from national registries, and only one provided information collected from hospital medical records. Beyond the actual trend over time, our study reported a pooled global incidence rate (IR) of PTC and FTC in the pediatric age of 0.46 (95% CI: 0.33–0.59) and 0.07 (95% CI: 0.02–0.12) per 100,000 person-years, respectively. The highest IRs were recorded among Caucasian girls, and the lowest in black or other races/ethnicities.ConclusionOur data confirm that DTC in the pediatric population is a rare condition. The pooled IRs of the studies included in this meta-analysis are ~0.5 for PTC, which is the most common histological type when both genders and all age groups are considered. The implementation of a prospective international registry on pediatric DTC, as part of the wider European Registries for Rare Endocrine Conditions, has been recently proposed. In addition to providing relevant information on the clinical behavior of this rare disease, standardization of data collection will be pivotal to fill current gaps and allow an accurate estimation of the real incidence and risk factors of DTC
Hashimoto’s thyroiditis, hypoparathyroidism and coeliac disease: lessons from a rare association
We present the case of a 36 years old woman, affected by euthyroid Hashimoto’s thyroiditis (HT) from the age of 20. She reported the following symptoms for three years: weight reduction, abdominal pain, alternate constipation and diarrhoea, tiredness, paresthesias and cramps. Biochemical evaluation revealed low iron levels (21 ug/dl, with microcytic anemia) and hypocalcemia (6.6 mg/dl), first attributed to coeliac disease (EMA IgG, AGA IgG-A and tTG IgA positivity; Marsh-Oberhuber 3a/3b type at duodenal biopsy). TSH, PTH and 25-OHD3 were in the normal range. Although the patient was on a gluten-free diet for the second year, cramps persisted and facial spasms and tetanic crises appeared. One year later she came to our attention with severe hypocalcemia (Ca 5.1 mg/dl, Ca++ 0.6 nmol/L) and low PTH (2.5 pg/ml). A diagnosis of primary hypoparathyroidism was made and conventional treatment was started. In the following months, symptomatic hypocalcemia persisted (6.7 mg/dl, Ca++ 0.7 nmol/L), despite the gradual increase of calcium and calcitriol supplements. Gastro-intestinal re-evaluation demonstrated gluten contamination, so as to hypothesize that the scarce dietary compliance had caused persistent malabsorption and had made the hypocalcemia difficult to manage. The observation of these three disorders coexisting in a single patient, never reported by the literature, warns us about the virtually unlimited possibilities of autoimmune disease clustering. Clinicians should be aware of the increased risk of developing additional AIDs in patients with one autoimmune disorder
An unusual cause of chest pain
Case report :We present the case of a 27year-old male who went to the Emergency Room for the acute onset of chest pain irradiated to left flank and fever by 2 days. An abdominal computed tomography (CT) scan, performed for the suspicion of a kidney stone, showed a left basal pulmonary opacity. The patient was admitted to our department for suspected community-acquired pneumonia (CAP) but, a few days later, a chest CT scan with intravenous contrast revealed a thoracic congenital malformation: intralobar pulmonary sequestration. The pulmonary lesion was resected and the histopathological examination of the lesion showed the features of pulmonary sequestration.
Conclusions :Pulmonary sequestration is a rare congenital malformation that is usually diagnosed in the Pediatric age. We report here an unusual case of intralobar pulmonary sequestration in an adult mimicking a CAP and a lung cancer
Vaccination coverage in healthcare workers: a multicenter cross-sectional study in Italy
IntroductionIn recent years, a phenomenon known as "vaccine hesitancy" has spread throughout the world, even among health workers, determining a reduction in vaccination coverage (VC). A study aimed at evaluating VC among healthcare workers (HCWs) in 10 Italian cities (L'Aquila, Genoa, Milan, Palermo, Sassari, Catanzaro, Ferrara, Catania, Naples, Messina) was performed.Materials and methodsAnnex 3 of the Presidential Decree n. 445 of 28 December 2000 was used to collect information on the vaccination status of HCWs. The mean and standard deviation (SD) were calculated with regard to the quantitative variable (age), while absolute and relative frequencies were obtained for categorical data (sex, professional profile, working sector, vaccination status). The connection between VC and the categorical variables was evaluated by chi-square method (statistical significance at p<0.05). The statistical analyses were performed by SPSS and Stata software.ResultsA total of 3,454 HCWs participated in the project: 1,236 males and 2,218 females. The sample comprised: physicians (26.9%), trainee physicians (16.1%), nurses (17.2%) and other professional categories (9.8%). Low VC was generally recorded. Higher VC was found with regard to polio, hepatitis B, tetanus and diphtheria, while coverage was very low for measles, mumps, rubella, pertussis, chickenpox and influenza (20-30%). ConclusionsThis study revealed low VC rates among HCWs for all the vaccinations. Measures to increase VC are therefore necessary in order to prevent HCWs from becoming a source of transmission of infections with high morbidity and/or mortality both within hospitals and outside
