Psychosocial Morbidity and its Correlates in Cancer Patients of the Mediterranean Area: Findings from the Southern European Psycho-Oncology Study

BACKGROUND: A few and partial data are available on psychosocial morbidity among cancer patients in Mediterranean countries. As a part of a more general investigation (Southern European Psycho-Oncology Study-SEPOS), the rate of psychosocial morbidity and its correlation with clinical and cultural variables were examined in cancer patients in Italy, Portugal and Spain. METHODS: A convenience sample of cancer outpatients with good performance status and no cognitive impairment were approached. The Hospital Anxiety-Depression scale (HAD-S), the Mini-Mental Adjustment to Cancer scale (Mini-MAC), and the Cancer Worries Inventory (CWI) were used to measure psychological morbidity, coping strategies and concerns about illness. RESULTS: Of 277 patients, 34% had pathological scores ("borderline cases" plus "true cases") on HAD-S Anxiety and 24.9% on HAD-S Depression. Total psychiatric "caseness" was 28.5% and 16.6%, according to different HAD cut-offs (14 and 19, respectively). Significant relationships of HAD-S Anxiety, HAD-S Depression, HAD-S Total score, with Mini-MAC Hopeless and Anxious Preoccupation, and CWI score were found. No differences emerged between countries on psychosocial morbidity, while some differences emerged between the countries on coping mechanisms. Furthermore, Fatalism, Avoidance and marginally Hopeless were higher compared to studies carried out in English-speaking countries. LIMITATIONS: The relatively small sample size and the good performance status prevent us to generalize data on patients with different cancer sites and advanced phase of illness. CONCLUSIONS: One-third of the patients presented anxiety and depressive morbidity, with significant differences in characteristics of coping in Mediterranean countries in comparison with English-speaking countries.

Utilidade do Doppler Tecidular na Predição de Eventos Arrítmicos em Adultos com Tetralogia de Fallot Corrigida

INTRODUCTION: Adults with repaired tetralogy of Fallot (TOF) may be at risk for progressive right ventricular (RV) dilatation and dysfunction, which is commonly associated with arrhythmic events. In frequently volume-overloaded patients with congenital heart disease, tissue Doppler imaging (TDI) is particularly useful for assessing RV function. However, it is not known whether RV TDI can predict outcome in this population. OBJECTIVE: To evaluate whether RV TDI parameters are associated with supraventricular arrhythmic events in adults with repaired TOF. METHODS: We studied 40 consecutive patients with repaired TOF (mean age 35 +/- 11 years, 62% male) referred for routine echocardiographic exam between 2007 and 2008. The following echocardiographic measurements were obtained: left ventricular (LV) ejection fraction, LV end-systolic volume, LV end-diastolic volume, RV fractional area change, RV end-systolic area, RV end-diastolic area, left and right atrial volumes, mitral E and A velocities, RV myocardial performance index (Tei index), tricuspid annular plane systolic excursion (TAPSE), myocardial isovolumic acceleration (IVA), pulmonary regurgitation color flow area, TDI basal lateral, septal and RV lateral peak diastolic and systolic annular velocities (E' 1, A' 1, S' 1, E' s, A' s, S' s, E' rv, A' rv, S' rv), strain, strain rate and tissue tracking of the same segments. QRS duration on resting ECG, total duration of Bruce treadmill exercise stress test and presence of exercise-induced arrhythmias were also analyzed. The patients were subsequently divided into two groups: Group 1--12 patients with previous documented supraventricular arrhythmias (atrial tachycardia, fibrillation or flutter) and Group 2 (control group)--28 patients with no previous arrhythmic events. Univariate and multivariate analysis was used to assess the statistical association between the studied parameters and arrhythmic events. RESULTS: Patients with previous events were older (41 +/- 14 vs. 31 +/- 6 years, p = 0.005), had wider QRS (173 +/- 20 vs. 140 +/- 32 ms, p = 0.01) and lower maximum heart rate on treadmill stress testing (69 +/- 35 vs. 92 +/- 9%, p = 0.03). All patients were in NYHA class I or II. Clinical characteristics including age at corrective surgery, previous palliative surgery and residual defects did not differ significantly between the two groups. Left and right cardiac chamber dimensions and ventricular and valvular function as evaluated by conventional Doppler parameters were also not significantly different. Right ventricular strain and strain rate were similar between the groups. However, right ventricular myocardial TDI systolic (Sa: 5.4+2 vs. 8.5 +/- 3, p = 0.004) and diastolic indices and velocities (Ea, Aa, septal E/Ea, and RV free wall tissue tracking) were significantly reduced in patients with arrhythmias compared to the control group. Multivariate linear regression analysis identified RV early diastolic velocity as the sole variable independently associated with arrhythmic history (RV Ea: 4.5 +/- 1 vs. 6.7 +/- 2 cm/s, p = 0.01). A cut-off for RV Ea of < 6.1 cm/s identified patients in the arrhythmic group with 86% sensitivity and 59% specificity (AUC = 0.8). CONCLUSIONS: Our results suggest that TDI may detect RV dysfunction in patients with apparently normal function as assessed by conventional echocardiographic parameters. Reduction in RV early diastolic velocity appears to be an early abnormality and is associated with occurrence of arrhythmic events. TDI may be useful in risk stratification of patients with repaired tetralogy of Fallot.

Giant Interatrial Septal Aneurysms Mimicking Quistic Masses. Two Cases with Different Therapeutic Options

With the recent technical improvement in echocardiography imaging (second harmonics) the number of interatrial septum aneurysms (ASA) increased and are easily recognized. We assist to an overdiagnosing number of cases and diagnostic criteria emerged to face this problem. In the great majority of the cases ASA are small and inoffensive, but as ASA is considered a risk factor for cardioembolism when associated with persistence of foramen oval (PFO), an examination by transesophageal echocardiography (TEE) for exclusion of PFO makes the sense and is a common testing in patients with cryptogenic stroke. Besides these frequent ASA, other forms exist; the authors describe two cases of uncommon and huge ASA, one mimicking a right atrial tumor and the other a quistic, hipoechoic mass. The first case was associated with mitral stenosis and was submitted to surgery and the second was closed with an Amplatzer occluder device usually used in atrial septal defect (ASD).

Compressão Extrínseca ou Intrínseca Congénita da Via Aérea e Infecções Respiratórias - A Propósito de Três Casos Clínicos

A imaturidade das vias aéreas e a susceptibilidade às infecções, no lactente, são factores que condicionam a expressividade clínica de malformações do aparelho respiratório, muitas vezes "rotuladas" como bronquiolites ou outras infecções respiratórias comuns. No entanto, a evolução atípica ou a recorrência são sinais que alertam para a possibilidade de existirem situações clínicas menos frequentes subjacentes. Assim, e curiosa verificar que, nos casos clínicos apresentados, 0 diagnóstico inicial de infecção respiratória com componente obstrutivo baixo conduziu a identificação de malformações congénitas da via aérea.

Alcohol Septal Ablation in Obstructive Hypertrophic Cardiomyopathy: Four Years of Experience at a Reference Center

INTRODUCTION: We describe our center's initial experience with alcohol septal ablation (ASA) for the treatment of obstructive hypertrophic cardiomyopathy. The procedure, its indications, results and clinical outcomes will be addressed, as will its current position compared to surgical myectomy. OBJECTIVE: To assess the results of ASA in all patients treated in the first four years of activity at our center. METHODS: We retrospectively studied all consecutive and unselected patients treated by ASA between January 2009 and February 2013. RESULTS: In the first four years of experience 40 patients were treated in our center. In three patients (7.5%) the intervention was repeated. Procedural success was 84%. Minor complications occurred in 7.5%. Two patients received a permanent pacemaker for atrioventricular block (6% of those without previous pacemaker). The major complication rate was 5%. There were no in-hospital deaths; during clinical follow-up (22 ± 14 months) cardiovascular mortality was 2.5% and overall mortality was 5%. DISCUSSION AND CONCLUSION: The results presented reflect the initial experience of our center with ASA. The success rate was high and in line with published results, but with room to improve with better patient selection. ASA was shown to be safe, with a low complication rate and no procedure-related mortality. Our experience confirms ASA as a percutaneous alternative to myectomy for the treatment of symptomatic patients with obstructive hypertrophic cardiomyopathy refractory to medical treatment.

Atrial Septal Defects

Atrial septal defects are the third most common type of congenital heart disease. Included in this group of malformations are several types of atrial communications that allow shunting of blood between the systemic and the pulmonary circulations. Most children with isolated atrial septal defects are free of symptoms, but the rates of exercise intolerance, atrial tachyarrhythmias, right ventricular dysfunction, and pulmonary hypertension increase with advancing age and life expectancy is reduced in adults with untreated defects. The risk of development of pulmonary vascular disease, a potentially lethal complication, is higher in female patients and in older adults with untreated defects. Surgical closure is safe and effective and when done before age 25 years is associated with normal life expectancy. Transcatheter closure offers a less invasive alternative for patients with a secundum defect who fulfil anatomical and size criteria. In this Seminar we review the causes, anatomy, pathophysiology, treatment, and outcomes of atrial septal defects in children and adult patients in whom this defect is the primary cardiac anomaly.

Aggressive Pituitary Lesion with a Remarkably High Ki-67

Os raros tumores pituitários agressivos são chamados carcinomas quando são detectadas metástases, sejam sistêmicas e/ou em sistema nervoso central. Alguns casos estão associados com superprodução de hormônio, mas a maioria é diagnosticada em função dos sintomas locais. Essas neoplasias são geralmente refratárias aos tratamentos atuais. Uma mulher com 51 anos de idade apresentou dor de cabeça de início súbito, paralisia de braço esquerdo e hipoestesia facial esquerda. A tomografia e a ressonância magnética revelaram um tumor pituitário invadindo os seios esfenoidal e cavernoso esquerdos. Os dados laboratoriais excluíram hipersecreção hormonal. A paciente foi submetida à cirurgia transesfenoidal, e os achados histológicos mostraram uma neoplasia com Ki-67 estimado em 75%. As imagens excluíram tanto um tumor oculto primário quanto disseminação sistêmica ou do sistema nervoso central. Três semanas após a cirurgia, a condição neurológica apresentou piora com início de ataxia, ptose bilateral, oftalmoplegia e aumento do tamanho da lesão, levando à intervenção cirúrgica por craniotomia, seguida por apenas algumas sessões de radioterapia devido à progressão grave da doença. A paciente veio a óbito depois de quase dois meses das manifestações iniciais. O caso ilustra a agressividade de algumas lesões pituitárias, a eficácia limitada das modalidades atuais de tratamento, como a cirurgia ou a radioterapia, e as limitações da classificação atual de tumores pituitários. Até onde sabemos, esse caso corresponde a uma das neoplasias pituitárias mais agressivas descritas até hoje, com um nível muito alto de Ki-67 (75%) e sobrevida curta (2 meses). O nível de Ki-67 pode ser de valor prognóstico em tumores pituitários. A classificação da Organização Mundial da Saúde (OMS) para tumores pituitários deveria ser revisitada.

Melanoma and Satellite Blue Papule

The colors that are seen in dermoscopy depend on the anatomic level of the skin at which the chromophores are seen. Blue color can be found in a variety of melanocytic and nonmelanocytic lesions. An 89-year-old man presented with a 3-year history of a slow-growing, hyperpigmented patch located on the distal third of the right arm. Dermoscopy showed an atypical network, irregularly distributed globules, pigmented internal streaks and a milky-red area. Based on these findings a diagnosis of slow-growing malignant melanoma was made. Simultaneously, a well-defined blue papule was seen on the proximal third of the same arm. Dermoscopy disclosed a homogeneous blue pattern. After clinical and dermoscopic correlation our differential diagnosis for this blue lesion included cutaneous melanoma metastasis, blue nevus and foreign body reaction. The patient recalled its onset 75 years ago after a grenade explosion. We also discuss the blue lesion appearance under reflectance confocal microscopy and high-definition optical coherence tomography. Histopathological examination after excision of the hyperpigmented patch and blue papule revealed a melanoma in situ and a foreign body reaction, respectively. The diagnostic evaluation of a blue lesion should always rely on the integration of all data, especially clinical and dermoscopic features. Other non-invasive techniques, like reflectance confocal microscopy and high-definition optical coherence tomography can also be important aids for its differential diagnosis.
