Depressive symptoms in involuntary hospitalized patients in Cyprus: Socio-demographic and psychopathological characteristics.

Τhe severity and variation of depressive symptoms (DS), among psychotic individuals under involuntary hospitalization is unclear. We investigated the socio-demographic and clinical characteristics of psychotic adults with DS involuntarily hospitalized for compulsory treatment in Cyprus. We also evaluated the psychometric properties (internal consistency, known-group and discriminant validity) of the HDRS-17 and HAM-A for the assessment of depressive and anxiety symptoms, respectively. A descriptive correlational study with cross-sectional comparisons was applied. Data on demographics, cognitive functioning (MoCA scale), depressive (HDRS-17 scale), anxiety (HAM-A scale) and psychotic (PANSS scale) symptoms were collected (December 2016 -February 2018). Following informed consent, the sample included 406 patients. Among them, 21 males and 23 females reported DS (HDRS-17 total score ≥8). The latter were mainly Greek-Cypriots (61.4%), 45-65 years old (38.6%), single (77.3%), unemployed (72.7%), mainly admitted due to aggressiveness towards others (47.7%), most frequently diagnosed with a bipolar disorder (59.1%). The mean score (M) in the HDRS-17 was 30.72 (scale range: 8-50; Standard Deviation [SD]: 10.42). The highest mean score (M) per item was in the variables "Suicide behavior"'(M:3.09; SD:1.09) and "Depressive mood" (M=2.95; SD=1.07). The DS group (HDRS-17 score≥8) reported higher PANSS positive symptoms subscale score (t-test, p=0.003) and HAM-A total score (t-test, p=0.05) compared to the non-DS group (HDRS-17 score<8). In multivariable logistic regression analysis only female sex [OR (95%CI) = 3.28 (1.33.-8.04), p=0.01)] and a mood disorder diagnosis [OR95% CI: 15.22(4.13.-56.14), p<0.0001)] retained a statistically significant association with DS. Cronbach' s alpha was 0.827 for the HDRS, and 0.763 for the HAM-A. The present findings partially support the known-group validity of the HDRS-17 and the ΗΑΜ-Α, and the discriminant validity of the HDRS-17 in psychotic patients under involuntary hospitalization. Additionally, the most frequent diagnosis in the DS group was a bipolar disorder, and the most frequent admission cause was aggressiveness towards others; it is possible that the majority of the DS group participants were patients with a bipolar disorder in episodes with mixed features, presenting simultaneously depressive symptoms and aggressiveness. Further studies on relapse prevention regarding this clinical group are proposed, as well as studies on specificity and sensitivity of the HDRS-17 and HAM-A.

White-coat hypertension during coronary computed tomography angiography is associated with higher coronary atherosclerotic burden.

INTRODUCTION: White-coat hypertension (WCH) is a prevalent entity, which has been associated with an increased cardiovascular risk. AIM: Assess whether WCH is associated with a higher coronary atherosclerotic burden, evaluated by coronary computed tomography angiography (CCTA) and coronary artery calcium (CAC) scoring. METHODS: A total of 1362 patients who performed CCTA and simultaneous CAC for the assessment of coronary artery disease (CAD) were prospectively enrolled in a single-center registry and divided into three groups: (A) patients with normal blood pressure (BP) (n=386); (B) patients with WCH (n=174; without a history of hypertension or antihypertensive medication, but with systolic BP ≥140 and/or diastolic BP ≥90 mmHg before examination acquisition); and (C) patients with hypertension (n=802). The following coronary atherosclerotic markers were evaluated: CAC above the 50th percentile (CAC>p50), prevalence of CAD (any plaque), and obstructive CAD (plaque with>50% stenosis). RESULTS: Patients with WCH had a higher coronary atherosclerotic burden compared with patients with normal BP for all markers (30.5 vs. 19.4%, P=0.004 for CAC>p50; 50.6 vs. 36.8%, P=0.002 for CAD, any plaque; and 13.8 vs. 8.3%, P=0.045 for obstructive CAD). On multivariate analysis, WCH was an independent predictor of a CAC>p50 [odds ratio (OR) 1.563, 95% confidence interval 1.018-2.400, P=0.041], but not of the presence of CAD (any plaque) (OR 1.335, P=0.169) or obstructive CAD (OR 1.376, P=0.301). CONCLUSION: In this registry of patients, WCH was an independent predictor of a CAC above the p50. It was also associated with higher other markers of coronary atherosclerotic burden, such as the presence of CAD on CCTA, compared with patients with normal BP.

A systemic disease un suspected by physical examination.

A 73-year-old man was admitted to the cardiology department with unstable angina. He had a history of macroglossia with 3 years of development, attributed to hypothyroidism. On physical examination, he presented an exuberant macroglossia. The following diagnostic procedures were performed-ECG, in sinus rhythm with low voltage criteria, and transthoracic echocardiography, which revealed a left ventricle with preserved function and marked wall thickening, with low strain values in basal segments. The coronary angiography confirmed a lesion of 90% in the right coronary artery, treated with two stents. Suspecting a systemic infiltrative disease, additional tests were performed and these revealed the presence of systemic amyloid light-chain (AL) amyloidosis with cardiac involvement, associated with multiple myeloma. The patient was sent to a consult of haematology to begin chemotherapy.

Retinal artery embolization complicating Libman-Sacks endocarditis in a systemic lupus erythematosus patient.

Libman-Sacks endocarditis (LSE) is the most characteristic cardiac manifestation of systemic lupus erythematosus (SLE). It is usually clinically silent but heart failure due to valvular dysfunction, secondary infective endocarditis and embolic phenomena can complicate valvular abnormalities. We present a patient with SLE and blindness due to right central retinal artery occlusion. Echocardiographic examination revealed a verrucous vegetation on the posterior mitral valve leaflet consistent with LSE. Anticoagulation therapy was started. Echocardiographic regression of the vegetation was observed and there has been no recurrence of thromboembolic events to date.

Study of aflatoxin B1 production by Aspergillus parasiticus in bee pollen of Greek origin.

Aflatoxin B1 (AFB1) is a carcinogenic metabolite produced by certain Aspergillus species such as A. parasiticus and A. flavus. The beneficial properties of bee pollen have transformed this commodity into an increasingly frequent component of the human diet. As bee pollen is a substrate on which aflatoxigenic fungi can grow, AFB1 production is likely. In the present study, we describe a method for aflatoxin B1 determination in bee pollen utilising high pressure liquid chromatography (HPLC) with a fluorescence detector (FD). The recovery factor of the method was found to be 111% (RSD% 1.61), while the detection limit (LOD) was 0.08 ng AFB1/g. An additional aim of this study was to investigate the growth of A. parasiticus and AFB1 production in bee pollen. Results indicated that no mycelial growth was observed and no AFB1 was detected in bee pollen samples containing natural microbiota throughout the entire observation period (20 days). In contrast, AFB1 production in treated bee pollen samples (15 g pollen/flask) inoculated with A. parasiticus was significantly higher (p ≤ 0.05) compared to control samples (treated but not inoculated) throughout the entire incubation period, while no mycelial growth was apparent. Maximum production was observed on the 12th day (79.29 ng AFB1/flask and 32.44 ng AFB1/flask for inoculated and non-inoculated bee pollen, respectively). As a result, AFB1 production in bee pollen is likely even following a minor contamination, which could occur randomly.

Myocardial infarction as the first probable manifestation of caseous calcification of the mitral annulus.

Calcification of the mitral annulus is a common echocardiographic finding during routine evaluation of patients. Caseous calcification of the mitral annulus (CCMA) on the other hand is a rare variant, occurring in about 0.06-0.07% of echocardiographic studies. The authors present the case of a 73-year-old woman admitted to hospital with an anterior wall acute coronary syndrome, in whom transthoracic echocardiography showed a well-defined echogenic rounded mass measuring 27 x 22 mm in diameter attached to the posterior mitral annulus. After transesophageal echocardiography and magnetic nuclear imaging, which confirmed the characteristics of the mass, the patient underwent surgical resection of the mass and mitral replacement with a mechanical prosthetic valve. Histological examination confirmed the diagnosis. Systemic embolism associated with CCMA is a rare but possible complication and was probably the cause of the acute coronary syndrome in this patient.

Cardiomyopathy in Churg-Strauss syndrome.

The authors present the case of a 56-year-old man, admitted to the hospital twice in ten days for acute coronary syndrome with normal coronary angiograms. In the second hospitalization, the patient had anginal crises that did not respond to anti-ischemic therapy, associated with cough and wheezing. The echocardiogram revealed worsening left ventricular systolic dysfunction. He had no cardiovascular risk factors but there was a history of bronchial asthma, allergic rhinitis and peripheral neuropathy of the left upper limb with paresthesias. Laboratory studies showed eosinophilia, detected in previous blood tests, although more marked than before. Chest X-rays showed non-fixed pulmonary infiltrates and bronchoalveolar lavage revealed increased lymphocytes and eosinophils, suggesting Churg-Strauss syndrome with the probable cardiac manifestation of coronary vasospasm. A cardiac MRI was also performed but was inconclusive due to the patient's intolerance of the exam.

Transesophageal echocardiography in an emergency setting. A district general hospital experience.

Transesophageal echocardiography is an extremely useful technique for the study of various cardiovascular pathologies. In the particular setting of emergency, it is of great value for prompt diagnosis and appropriate therapy. It was our aim to evaluate, in our hospital, the benefits obtained by the use of transesophageal echocardiography in an emergency setting. We retrospectively studied patients who underwent transesophageal echocardiography (TEE) in an emergency setting, from June 1997 to December 2002, evaluating demographic characteristics, indication to perform TEE, benefit obtained (diagnosis or exclusion of initial diagnosis), and technique-related complications. There were 97 transesophageal echocardiograms performed in an emergency setting in the period under consideration, accounting for 19.3% of the total number of exams. Fifty-two patients (53.6%) were male, mean age 63.9 +/- 12.7. Nineteen patients (19.6%) were on assisted ventilation. The indications to perform TEE were: possible massive or submassive pulmonary thromboembolism in 32 patients (33.0%); suspected aortic dissection in 19 (19.6%); shock with inconclusive transthoracic echocardiogram in ten (10.3%); possible endocarditis in eight (8.2%); possible prosthetic valve dysfunction in seven (7.2%); intracardiac mass in six (6.2%); search for cardiac source of embolism in five (5.2%); possible mechanical complication of acute myocardial infarction in four (4.1%); pre-electrical cardioversion study in four patients with atrial fibrillation (4.1%); and suspected congenital heart disease in two (2.1%). TEE examination yielded additional information and helped in the therapeutic decision in 88 patients (90.7%), leading to a diagnosis in 49 (50.6%), which was different from the initial diagnostic hypothesis in four, and exclusion of the suspected diagnosis in 39 (40.1%). There was only one minor complication (1.0%) and no TEE-related mortality. We concluded that transesophageal echocardiography is an extremely useful and safe cardiovascular diagnostic technique in an emergency setting in a district general hospital, enabling a diagnosis to be reached or excluded in almost all patients, which is essential for implementing appropriate therapy.

Vaccination against hepatitis A during outbreaks starting in schools: what can we learn from experiences in central Italy?

Two outbreaks of hepatitis A started almost simultaneously in a maternal school and in a day care centre located at opposite sides of Florence, Italy, at the end of 2002. Both of them originated from immigrant children, and in both cases, hepatitis A was initially not recognised due to aspecific symptoms. While vaccination of contacts started with delay in the first outbreak, the same intervention was organised and performed in 3 days in the other. The outbreak starting in the maternal school caused 30 notified cases, plus 7 cases diagnosed retrospectively. Nine of them were in a secondary school, where vaccination (in accordance with the Italian national guidelines on hepatitis A (HA) vaccination) had been started only after a secondary case occurred. Only three cases occurred overall in the other outbreak starting in the day care centre, where >80% of infants, children and personnel were immunised. Although few asymptomatic infections probably occurred, no source of contagion existed any longer 2 months after immunisation. A rapid vaccination of school and family contacts of hepatitis A cases after the first case (irrespective of school grade) seems to play an important role to shorten outbreak duration.
