Multimodality Imaging in Right Heart Tumors: Proposed Algorithm towards an Appropriate Diagnosis

A right heart tumor can be identified by transthoracic echocardiography during a routine examination or due to cardiac symptoms. The first step is the assessment by echocardiography, with its multiple techniques, and the obtained information must be judged in a clinical and biological context. The second step comprises one, sometimes even two, of the more complex modality imaging methods. The choice is driven not only by the advantages of each imaging technique but also by local expertise or the preferred imaging modality in the center. This step is followed by staging, follow-up, and/or imaging-guided excision or biopsy, which is performed in selected cases in order to obtain anatomopathological confirmation. In the presence of features suggestive of malignancy or causing hemodynamic impairment, a transvenous biopsy is essential before the more complex imaging modalities (which are still relevant in the staging process). Using a structured imaging approach, it is possible to reach an appropriate diagnosis without a biopsy. Frequently, these imaging techniques have a complementary role, so an integrated imaging approach is recommended. This proposed algorithm for appropriate diagnosis of right heart tumors could serve as a practical guide for clinicians (not only imaging specialists).

Epidemiological and histopathological aspects of ocular melanomas in Northeastern Romania

Ocular melanoma is a rare but complex disease in current medical practice. Our retrospective study spans over a period of 28 years and analyzed uveal and conjunctival melanomas that were consecutively admitted, diagnosed, and treated in the 2nd Ophthalmology Clinic of Prof. Dr. Nicolae Oblu Emergency Clinical Hospital, Iaşi, Romania. The patients were selected from the records of the Department of Pathology of our Hospital, being diagnosed by standard histopathological techniques. The aim of this study was to summarize the epidemiological and pathological aspects of uveal and conjunctival melanomas in Northeastern region of Romania. In our study, we did not notice a predilection of uveal and conjunctival melanoma to one particular gender. The most common histological subtypes of ocular melanomas were the heavily pigmented spindle cell subtype, followed by the epithelioid subtype. Our patients sought medical help in a timely manner, before the systemic invasion of the disease could develop.

Multimodality imaging approach of patent foramen ovale: Practical considerations for transient ischemic attack/stroke

A patent foramen ovale, which is present in up to 25% of the population, is a risk factor for cryptogenic stroke (which accounts for 15%-40% of strokes) and transient ischemic attack via paradoxical embolism. This narrative review focuses on the multimodality imaging approach of the diagnosis and periprocedural guidance of patent foramen ovale, with an emphasis on the use of agitated saline as contrast medium in echocardiography, starting from embryologic aspects. Therefore, we aimed to make a concise and complete presentation of the protocol used for this type of evaluation, along with multimodality imaging approach of the patent foramen ovale and practical considerations for transient ischemic attack/stroke.

Modern Approaches for the Treatment of Heart Failure: Recent Advances and Future Perspectives

Heart failure (HF) is a progressively deteriorating medical condition that significantly reduces both the patients’ life expectancy and quality of life. Even though real progress was made in the past decades in the discovery of novel pharmacological treatments for HF, the prevention of premature deaths has only been marginally alleviated. Despite the availability of a plethora of pharmaceutical approaches, proper management of HF is still challenging. Thus, a myriad of experimental and clinical studies focusing on the discovery of new and provocative underlying mechanisms of HF physiopathology pave the way for the development of novel HF therapeutic approaches. Furthermore, recent technological advances made possible the development of various interventional techniques and device-based approaches for the treatment of HF. Since many of these modern approaches interfere with various well-known pathological mechanisms in HF, they have a real ability to complement and or increase the efficiency of existing medications and thus improve the prognosis and survival rate of HF patients. Their promising and encouraging results reported to date compel the extension of heart failure treatment beyond the classical view. The aim of this review was to summarize modern approaches, new perspectives, and future directions for the treatment of HF.

Clinical and immunohistopathological study of conjunctival melanocytic lesions in pediatric and adolescent patients. A case series

Background: Conjunctival pigmented neoplasia can be benign, premalignant or malignant tumors. Our study aims to establish the epidemiological, gross morphological and immunohistopathological features of the conjunctival pigmented lesions in pediatric and adolescent patients (<18 years), to establish an accurate diagnosis. Patients, Material and Methods: This is a retrospective case series study conducted within two Ophthalmology Clinics from Iaşi, Romania, on seven pediatric and adolescent patients. Using the Clinical Observation Chart and the Pathology Registers over a six-years period (January 2015–December 2021), we noted the patients’ demographic data, clinical data, and ophthalmological investigations of the lesion, as well as the type of their treatment. All histological sections stained with Hematoxylin–Eosin (HE) and with five antibodies [pan-cytokeratin (pan-CK) AE1/AE3, S100 protein, Melan A, human melanoma black 45 (HMB45), and Ki67] were re-examined by four pathologists for each case, to identify the type of the conjunctival lesion and its histological and immunohistochemical features. Results: The mean age of all patients was 10.28 years, and the female/male ratio was 1.3. Right eye was more often affected (71.42%). 71.42% of cases presented an elevated lesion, 57.14% of cases showed a lightly pigmented lesion, but 14.28% of cases exhibited a pink lesion and this feature described the inflamed juvenile conjunctival nevus. In all cases (100%) the conjunctival pigmented tumor was removed with safety margins. The microscopic examination revealed a compound melanocytic nevus in 57.14% cases, a junctional conjunctival nevus in 14.28% cases, an inflamed juvenile nevus in 14.28% cases, and a conjunctival melanoma arising from a pre-existing nevus in 14.28% cases. In all cases of nevi, the nevoid melanocytes showed strong immunopositivity for Melan A and S100 protein, variable and weak immunopositivity for HMB45, and a mean Ki67 labeling index of 1.71%. Conjunctival melanoma revealed strong immunopositivity of tumor cells for HMB45, Melan A and S100 protein, and a Ki67 labeling index of 20%. In all cases, the conjunctival epithelium showed strong immunopositivity for pan-CK AE1/AE3. All our cases (100%) had a favorable outcome after the surgical removal of the tumor. Conclusions: Any excision of a conjunctival pigmented lesion must be subject to a systematic immunohistopathological examination, and there is a set of antibodies (anti-HMB45 and anti-Ki67) that are useful for differential diagnosis between a conjunctival nevus and a conjunctival melanoma.

Hereditary Hemorrhagic Telangiectasia and Arterio-Venous Malformations—From Diagnosis to Therapeutic Challenges

Hereditary hemorrhagic telangiectasia is a rare autosomal dominant vascular disease defined by the presence of mucosal and cutaneous telangiectasia and visceral arterio-venous malformations. The latter are abnormal capillary-free direct communications between the pulmonary and systemic circulations with the following consequences: arterial hypoxemia caused by right-to-left shunts; paradoxical embolism with transient ischemic attack or stroke and brain abscess caused by the absence of the normally filtering capillary bed; and hemoptysis or hemothorax due to the rupture of the thin-walled arterio-venous malformations (particularly during pregnancy). It is frequently underdiagnosed, commonly presenting as complications from shunting through arterio-venous malformations: dyspnea, chronic bleeding, or embolism. Arterio-venous malformations are present not only in the lungs, but can also be found in the liver, central nervous system (mainly in the brain), nasal mucosa, or the gastrointestinal tract. The first choice of therapy is embolization of the afferent arteries of the arterio-venous malformations, a minimally invasive procedure with a high efficacy, a low morbidity, and low mortality. Other therapeutic modalities are surgery (resection) or stereotactic radiosurgery (using radiation). Routine screening for arterio-venous malformations is indicated in patients diagnosed with this condition and can prevent severe complications such as acute hemorrhages, brain abscesses, or strokes. Clinicians should provide a long-term follow-up for patients with arterio-venous malformations, in an effort to detect their growth or reperfusion in case of previously treated malformations. In spite of two experts’ consensuses, it still possesses multiple therapeutic challenges for physicians, as several aspects regarding the screening and management of arterio-venous malformations still remain controversial. Multidisciplinary teams are especially useful in complex cases.

Complete oculomotor nerve palsy - first manifestation of gastric adenocarcinoma: clinical experience and literature review

The diagnosis and management of the alteration of the normal function of the oculomotor nerve (third cranial nerve) varies depending on the characteristics of the paralysis, the age of the patient, and the associated symptoms and signs. Oculomotor nerve palsy may be caused by lesions located anywhere from the oculomotor nucleus to the termination of the third nerve in the extraocular muscles. Although there have been significant advances in neuroimaging to facilitate early diagnosis, the management of a patient presenting with isolated oculomotor palsy is still challenging. This review tackles the case of a 52-year-old patient, with a history of pulmonary tuberculosis (at the age of five), referred to the Department of Ophthalmology, St. Spiridon Emergency Clinical Hospital, Iaşi, Romania. The patient had diplopia accompanied by right eyelid ptosis, symptoms that began suddenly 10 days before hospitalization. The clinical examination showed right eye grade II palpebral ptosis, exotropia with limitation of eyeball movements in adduction, supra-∕infraduction. Biomicroscopic examination of the anterior pole revealed the presence of anisocoria and light-near dissociation on the affected side. Numerous investigations were performed to identify the cause, starting with tumoral markers, which were within normal limits. Magnetic resonance angiography (MRA) was performed, and posterior communicating artery aneurysm was ruled out. The endocrinology examination and hormonal laboratory tests were also within normal parameters. Due to suspicions of generalized tuberculosis raised by the infectious disease doctor or presence of secondary lesions, thoraco-abdomino-pelvic computed tomography (CT) scan with contrast agent was done and its findings required gastroenterological exploration. After various explorations, the certainty diagnosis was set by histopathological examination, which revealed gastric adenocarcinoma.

Thymus pathology in myasthenia gravis with anti-acetylcholine receptor antibodies and concomitant Hashimoto's thyroiditis. A four-case series and literature review

Objective: Identifying the morphological features of thymus in patients with myasthenia gravis (MG) with anti-acetylcholine receptor (AChR) antibodies and concomitant Hashimoto’s thyroiditis (HT), which were recruited from a single surgical unit of a tertiary referral hospital located in the North-Eastern region of Romania, over a period of 11 years. Patients, Materials and Methods: We retrospectively reviewed clinical, imaging, laboratory, thymic pathology, and outcome data that were obtained from medical records of patients with MG and concomitant HT, to whom a thymectomy was performed for a suspected thymic lesion. All the surgical interventions were done in the Third Clinic of Surgery, St. Spiridon Emergency County Hospital, Iaşi, Romania, for an 11 years’ period, i.e., from January 1, 2000 and December 31, 2010. Results: Four patients (three females and one male) were included. The mean age of the patients at the time of their thymectomy was 40.25 years. Of all patients, 75% had moderate or severe MG, 100% had anti-AChR antibodies, and an electromyographic decrement greater than 25%. All patients have been diagnosed with HT in their past medical history by a full thyroid panel [high thyroid-stimulating hormone (TSH) values, low free thyroxine (fT4) values, and the presence of the anti-thyroid antibodies] and all of them have been treated with Euthyrox. Our four patients expressed different MG subtypes, each of them being associated with different thymus pathology. Thoracic computed tomography (CT) scan revealed heterogeneous mediastinal masses and established the correct diagnosis only in 25% of cases. The pathological exams also revealed a heterogeneous pattern of thymic lesions. In contrast with other studies, our patients with MG with anti-AChR antibodies and concomitant HT presented atrophic thymus more frequently (50%), but with particular morphological changes of Hassall’s corpuscles. Also, 25% of cases were diagnosed with thymic lympho-follicular hyperplasia (TLFH) associated with thymic epithelial hyperplasia. In B2 thymoma, neoplastic epithelial cells expressed cytokeratin 19 (CK19) immunoreactivity, high Ki67 labeling index and strong p63 immunopositivity. Conclusions: In our series, MG and HT occurred simultaneously, or one of them was diagnosed before the other, raising some new questions regarding the immune mechanism of these two autoimmune diseases. Due to the heterogeneous morphological changes of the thymus that we found in this study, we can hypothesize that thymus is involved in the pathogenic mechanism of MG with anti-AChR-antibodies and concomitant HT development.

Morphological and histopathological changes in placentas of pregnancies with intrauterine growth restriction

Aim: The definition of fetal growth restriction (FGR) refers to the incapability of a fetus to achieve the appropriate estimated growth, with expected fetal weight below the 10^th percentile calculated for its gestational age. Placental factors and hypoxemia are considered to be essential elements with influence on intrauterine growth restriction (IUGR) and fetal death. The purpose of the present study was to investigate the macroscopic and microscopic pathological findings regarding the placentas in pregnancies complicated by influence on IUGR. Patients, Materials and Methods: Our study included 42 third-trimester pregnant patients admitted to the Cuza Vodă Hospital of Obstetrics and Gynecology, Iaşi, Romania, in the last three years. Soon after delivery, the 42 placentas were collected and analyzed; 32 placentas came from cases previously diagnosed with influence on IUGR and were included in our study group. Ten other placentas included in the control group were selected from uncomplicated pregnancies. Standard Hematoxylin–Eosin (HE) staining method, as well as Periodic Acid–Schiff (PAS) staining, and immunohistochemical techniques for cluster of differentiation 31 (CD31) and collagen IV were used in order to highlight the morphological features of the studied placentas. Results: Our study revealed that reduced placental dimensions and eccentric umbilical cord insertion are correlated with the birthweight of the fetuses with IUGR (p<0.05). The most common histological finding in our study group was placental infarction later correlated with IUGR, but a certain causality could not be demonstrated, as this finding was also present in normal pregnancies. Other histopathological findings were also present in the influence on IUGR group, such as fibrin deposits, diffuse calcification, chronic villitis, avascular chronical villi, with no significant statistical correlations. CD31 was strongly immunoexpressed in the villous endothelial cells. Collagen IV presented a strong immunoreaction in the basement membrane and mesenchyme of the placental villi. Conclusions: Our study revealed a correlation between the dimensions of the diameters and volume of the maternal placenta and the presence of influence on IUGR. Moreover, it confirms the available data suggesting that the place of insertion of the umbilical cord is correlated with the weight of the fetus. Further studies with extended panel antibodies are needed in order to determine and complete the role of these morphological changes in the development of influence on IUGR.

The discovery of the circle of Willis as a result of using the scientific method in anatomical dissection

There are numerous articles on the discovery of this arterial polygon, its history being quite long, beginning with the Antiquity and up to the Modern Era. Making an analysis of the primary and secondary sources on this topic, the purpose of this article is to identify the significant moments of the discovery of this arterial polygon, which is an anatomical structure with great importance for neurologists and neurosurgeons. We will present the contributions to this topic from Renaissance and early Modern Era anatomists, such as Andreas Vesalius, Jean Fernel, Gabriel Fallopius, Giulio Cesare Casseri, Adriaan van den Spiegel, Johann Vesling, and Johann Jakob Wepfer von Schaffhausen. We also pointed out that the contribution of the famous British anatomist Sir Thomas Willis (1621-1675) was the most important one. He published De Cerebri Anatome, in 1664, in which he described the vascular arrangement laying at the base of the brain, accompanying it by the exquisite drawings of Christopher Wren. Thus, he demonstrated to the medical world that he had reached the greatest understanding of the structure and function of the circular arterial anastomosis. For this excellent discovery, his followers honored him by giving his name to this arterial circle.

The Myth of Prometheus in metastatic meningioma to the liver: from craniotomy to hepatectomy

Metastases from intracranial meningiomas are rare, and among them, meningiomas with hepatic dissemination are extremely rare. Therefore, there are currently no guidelines for staging and treatment of metastatic disease in meningioma, a disease that is a challenge for both the clinician and the pathologist. Our literature review revealed 24 cases of liver metastases originating from intracranial meningiomas. We used them to analyze the pathological patterns of dissemination and to assess the different management strategies available, the most efficient and beneficial being surgery and chemotherapy, especially in the case of meningiomas with hepatic and∕or systemic dissemination.

“The Silk Road” via subarachnoid cisterns

Meningiomas are generally slow-growing extra-axial benign tumours and in rare cases they can metastasize both neural and extra-neural. Intracranial meningiomas with leptomeningeal dissemination are extremely rare and the exact pathogenesis still remains unknown. The aim of this review is to analyse the pathways of intracranial and spinal metastatic spread of intracranial meningiomas and to discuss their particular clinical and pathological features. We highlight the fact that there is a possibility of leptomeningeal dissemination, even if cerebrospinal fluid cytology is negative, in patients with a medical history of a resected meningioma. We identified three possible ways of dissemination: haematogenous, through the CSF, or during surgery. From a histopathological point of view, the more malignant the meningioma, the more likely its leptomeningeal dissemination.

Protean cytological, histological and immunohistochemical appearances of medullary thyroid carcinoma: current updates

Medullary thyroid carcinoma (MTC) accounts for only 0.5-3% of all malignant diseases, but is responsible for more deaths every year than all the other endocrine malignancies taken together. Approximately 75-80% of MTCs occur sporadically, while the inherited forms of MTC are responsible for the rest of the cases. The heritable MTC results from a germline mutation in the rearranged during transfection (RET) proto-oncogene and is included into the multiple endocrine neoplasia 2 (MEN2), being associated with other endocrine abnormalities and clinical features. MTC is a neuroendocrine tumor that releases a wide range of secretory products that are responsible for a variety of symptoms, making it difficult to be diagnosed. For this reason, the pathological analysis is of vital importance to ensure that the correct diagnosis is made. This review presents the main data from the contemporary literature related to the pathological diagnosis of a patient with MTC and highlights the wide range of tumor cytological features, the many histological variants, as well as the particular tumor immunophenotype. It also reveals the new approach to this type of cancer in the new World Health Organization (WHO) Classification of Thyroid Tumors (2017) and the reassessment of MTC tumor category in the new American Joint Committee on Cancer∕Tumor, Node, Metastasis (AJCC∕TNM) Staging (2017).

Periocular basal cell carcinoma: demographic, clinical, histological and immunohistochemical evaluation of a series of 39 cases

BACKGROUND

Basal cell carcinoma (BCC) is the most frequent malignant epithelial tumor of the periocular area. The clinical and histological classification of periocular basal cell carcinoma (pBCC) is essential in order to establish the risk of recurrence and to compare the results of the treatment. Until now, there is no unitary histological classification of pBCC.

AIM

The aim of this study is to identify the demographic, clinical and histopathological characteristics of adult patients with pBCC, in order to obtain useful data for comparison in other investigations and to identify the histological origin of this eyelid tumor, as there are only hypothesis on this issue.

MATERIALS AND METHODS

A descriptive retrospective study was conducted on a series of 39 consecutive patients over the age of 20, who were surgically treated for pBCC in the 2nd Ophthalmology Clinic of the "Prof. Dr. Nicolae Oblu" Emergency Clinical Hospital from Iaşi, Romania, over an 11-year period (July 2007-February 2018). The analyzed data were the following: date of resection, patient age at resection, gender, tumor location, histological subtype, and immunohistochemical (IHC) expression patterns of anti-cytokeratin (CK) antibodies (anti-CK AE1∕AE3, anti-CK5∕6, anti-CK7, anti-CK17, anti-CK19, anti-CK20) and anti-epithelial membrane antigen (EMA) antibody.

RESULTS

A total of 39 histopathologically diagnosed cases of pBCC were evaluated. The mean age at resection was of 66 years (range: 26-87 years). As for gender, 17 (43.6%) were male patients, with a mean age of 64.84 years (range: 26-78 years) and 22 (56.4%) were female patients, with a mean age of 66.68 years (range: 46-87 years). The pBCC occurred on the right side in 18 (46.2%) cases and on the left in 21 (53.8%) cases. Of all removed specimens, 24 (61.53%) involved the lower eyelid, seven (17.94%) the medial canthus, five (12.82%) the upper eyelid, and three (7.62%) lacked the specification of the site. The most common histological subtype was nodular, accounting for 26 (66.7%) cases. Adenoid BCC was identified in four (10.3%) cases, and morpheaform in one (2.6%) case. Squamous differentiation (basosquamous subtype) was identified in eight (20.5%) cases. The IHC profile of pBCC included: strong immunopositivity for CK AE1∕AE3, and CK17 all histological subtypes, and CK5∕6 positivity only in squamous differentiation areas. No immunopositivity was identified for CK19, CK20, and EMA IHC staining.

CONCLUSIONS

Our retrospective study indicates that most of pBCCs developed particularly in elderly female patients and tumors were located in the lower eyelid with a left side and lower eyelid preferences. Most of our pBCC cases were histologically classified as nodular subtype, and morpheaform and basosquamous form affected mostly the lower eyelid. pBCC IHC profile showed a strong immunopositivity for CK17, thus suggesting that the origin of this cancer is in the follicular germinative cells. We can conclude that our results showed a demographic, clinical, histological, and IHC profile which seems to be representative for Central and Eastern European countries, maybe due to the same genetic predisposition and environmental factors.

The importance of clinical prediction models in non-fatal pulmonary embolism: an analysis of the best known clinical scores

The clinical evaluation in pulmonary embolism (PE) is the first instrument used by practitioners in the management of this potentially fatal pathology. The necessity of develop- ing certain valid and especially affordable practical instruments has led to the emergence of various clinical prediction models. The purpose of this paper is to analyze the main clinical scores, as a diagnostic or a prognostic tool, with their strengths and weaknesses. The PESI score, while relatively recent, remains the most investigated and validated prognostic score for the identification of the mortality risk and major adverse events, with economic implications of health services reduction costs through the accurate identification of patients with a low risk who are candidates of early hospital discharge. The simplified Geneva score (with a similar accuracy as the Geneva one) identifies a high or low PE probability, especially in combination with D-dimers, with a prognosis value as well. The Wells and simplified Wells scores identify the high or low probability, being improved by the level of D-dimers, having similar results with the Geneva score. The LR-PED score, conceived as an identification score for low risk, uses biochemical and electrocardiographic markers, but is less validated. The Vienna Prediction Model is another system for the evaluation of the recurrence in which the level of D-dimers is the main prediction factor. Other scores were evaluated with a statistically low significance. The Geneva and the PESI scores remain the most valuable instruments of diagnosis and clinical prognostic, respectively.

Massive pericardial effusion associated with hypothyroidism

The diagnosis of hypothyroidism is difficult because hypothyroidism in adults and especially the elderly, classic, has an insidious onset with a range of nonspecific symptoms which may delay diagnosis for months or even years. Old age seems to represent trigger factor for autoimmune diseases, including hypothyroidism. Clinical features in hypothyroidism, such as weight gain, fatigue, cold intolerance, constipation, dry skin, edema and muscle weakness, and decreased osteo-tendinous reflexes are usually subtle and can be overlooked. Thyroid dysfunction may be associated with a negative impact on the cardiovascular system. Pericardial, pleural and peritoneal effusions are common findings in hypothyroidism. This case report represents a typical primary hypothyroidism (autoimmune) and shows the clinical features of this disease. Basically we talked about a severe myxedema with the involvement of internal organs in an elderly woman and the euthyroidism restoration, under thyroid replacement therapy, was correlated with the clinical improvement and cardiovascular and neurological status, with radiographic remission and regression to extinction of pericardial effusion at repeated echocardiographic evaluations.

Thyroid dysfunction and ischemic heart disease--clinical correlations, progressive implications and impact on the prognosis

Thyroid dysfunctions are associated with systolic and diastolic heart dysfunction, hypertension, rhythm disorders, etc. Clinically significant hyperthyroidism and hypothyroidism may have an impact on the patients with ischemic heart disease.

OBJECTIVES

Investigation of the risk of developing ischemic heart disease, of the evolution and prognosis in relation to the entire spectrum of thyroid dysfunctions.

MATERIALS AND METHODS

All participants included in the study were selected from among subjects with heart disorders who were controlled with concern to the thyroid hormonal condition and who hadn't been treated previously for thyroid functional disorders. Based on these criteria we defined a study group made out of 791 subjects, divided into five lots based on the level of thyroid hormones. Once the group was formed, we conducted evaluations of the cardiovascular and thyroid status at 6 and 12 months, respectively.

RESULTS

In the witness lot, during monitoring 49% of the patients showed an ischemic heart disease. The main risk factors were: heart frequency of over 80 beats/min (RR = 1.83), age over 60 (RR = 1.47), female sex (RR = 1.21) and values of triglycerides over 160 mg/dl (RR = 1.23). In the group of patients with overt clinic hyperthyroidism, during monitoring 46.1% showed ischemic heart disease. The main risk factors were: heart frequency over 80 beats/min (RR = 2.41), age over 60 (RR = 1.67), high level of LDL-cholesterol (RR = 1.53) and female sex (RR = 1.31). Among the patients with overt clinical hyperthyroidism, during monitoring 53.3% showed ischemic heart disease. The main risk factors identified were: heart frequency over 80 beats/min (RR = 2.01), age over 60 (RR = 1.42), high levels of triglycerides (RR = 1.42) and LDL-cholesterol (RR = 1.32), as well as the presence of hypertension in the health records (RR = 1.31).

CONCLUSIONS

Thyroid dysfunction is a common clinical condition with a key role in the regulation of the cardiovascular system and may contribute to the evolution of the ischemic heart disease and which should be taken into consideration when patients with heart disease are treated. In this light, thyroid function needs to be evaluated for all patients with a risk for ischemic heart disease.

Risk assessment in the development of atrial fibrillation at patients with associate thyroid dysfunctions

Thyroid hormones are an important regulator of cardiac function and vascular system. Atrial fibrillation is a common cardiac arrhythmia and an important risk factor for the ischemic cerebral vascular accident and heart failure.

OBJECTIVES

The examination of the risk to develop atrial fibrillation in relation to the whole spectrum of thyroid dysfunctions.

MATERIAL AND METHODS

All participants to our study were selected from among subjects with cardiovascular disorders whose hormonal thyroid status had been controlled previously and who hadn't been treated for thyroid functional disorders. Based on these criteria we defined a study lot made up of 791 subjects, 700 women and 91 men, aged between 22 to 86, with a mean age of approximately 60 years old, divided into five groups, based on the level of thyroid hormones. Once the lot was constituted, evaluations were made of the cardiovascular and thyroid condition at 6 and 12 months.

RESULTS

During monitoring, most patients who developed atrial fibrillation were registered in the groups with manifest clinical hyperthyroidism, 34,62% and respectively with subclinical hypothyroidism, 38,6%. The main risk factors at the patients with manifest clinical hyperthyroidism were: female gender (RR=1.97) and age above 60 (RR=1.33), as well as the presence of coronary disease in the personal pathological record (RR=3.31), HBP (RR=1.46) and cardiac frequency in excess of 80 beats/min (RR=1.38). The main risk factors that led to atrial fibrillation among the patients with subclinical hypothyroidism, were: obesity (RR=2.21), the presence in the personal record of heart disease (RR=2,0), age over 60 (RR=1.90) and female sex (RR=1.30). At the patients who had been administered beta blockers prior to admission (RR=0.99), ACEI (RR=0.85) and/or antiarrythmic drugs (RR=0.54), the medication represented a protective factor against developing atrial fibrillation.

CONCLUSIONS

Thyroid dysfunctions are associated with an increased risk to develop atrial fibrillation, both in the case of clinically manifest and the subclinical manifest forms. These results support long term screening for thyroid dysfunctions for patients with atrial fibrillation.

[Multivalvular infective endocarditis with Enterococcus faecalis]

Infective endocarditis (IE) is a relatively rare disease that can take part of sepsis and may be a diagnostic and therapeutic challenge. Polyvalvular location of El is rare. We present a patient of 60 years diagnosed with plurivalvular infective endocarditis by Enterococcus faecalis with septic complications, visceral, dragged, hospitalized for a psychiatric pathology, who raised the problems of diagnosis and treatment, without being able to make assessments on the entrance gate. For help in diagnosing this case proved that cardiac ultrasound studies recommended that a screening method for patients with bacteremia, but the presence of vegetation is the major criterion for diagnosis of EI. Blood cultures and echocardiography led to the diagnosis of infectious endocarditis. Also abdominal ultrasound confirmed the clinical suggestion of gravity, the septic multiviscerale release by splenic abscess image objectivity. Under vigorous antibiotic treatment and symptomatic treatment in combination evolution was to worse, death occurring after 15 days of hospitalization, toxic-septic shock being irreversible. Our case is particular by locating polyvalvular vegetation, the germ involved, the court altered the immunological and disseminator septic complications that have limited therapeutic options and made predictable fatal diagnosis.

[Malignant hydatid disease--clinical case]

We report the case of a 79-year-old woman admitted for sepsis from a hepatic hydatid cyst with multiple disseminations diagnosed one month earlier who refused the surgical treatment. Her family history was irrelevant with regard to the circumstances leading to Taenia Echinococcus infestation, and given her poor health status and absence of previous medical documents no useful information was obtained from her medical history. The patient also presented chronic ischemic heart disease and anemia secondary to a bleeding duodenal ulcer, found at necropsy, which worsened the already unfavorable course by the acute hepatic and renal failure secondary to toxic and septic shock. Despite the complex treatment, death occurred 6 days later, following a second episode of upper digestive hemorrhage. Particular to this case is the absence in patient's history of the anaphylactic/allergic reactions suggestive of hepatic hydatid cyst dissemination.
