RESUMO

Paragangliomas are rare neuroendocrine tumors that arise from the extra-adrenal autonomic paraganglia, i.e., small organs consisting mainly of neuroendocrine cells that are derived from the embryonic neural crest and have the ability to secrete catecholamines. Paragangliomas can derive from either parasympathetic or sympathetic paraganglia. Most of the parasympathetic ganglia-derived paragangliomas are nonfunctional, and symptoms result from mass effect. Conversely, the sympathetic paragangliomas are functional and produce catecholamine. Although such patients could have symptoms similar to pheochromocytoma, mass effect symptoms, or non-specific symptoms, being benign tumors, they can also present with anemia, specifically iron-deficiency anemia. Considering that neoplastic pathology is chronically accompanied by moderate, normochromic, normocytic anemia, association between paragangliomas that are mostly benign but with a potential degree of malignancy and anemia is not as frequent as expected, with only 12 cases reported in the literature. We report a case of a 54-year-old female patient diagnosed with a paraganglioma of the carotid glomus accompanied by severe normochromic, normocytic anemia, which reached normal limits after excision of the paraganglioma.

RESUMO

Duplications and fenestrations of the internal jugular vein (IJV) are rare anatomic variations. There were previously found mostly unilateral fenestrated internal jugular veins, either empty, or traversed by the spinal accessory nerves. It was documented the computed tomography angiogram of a 65 year-old female patient and bilateral high fenestrations of the IJVs were found. On both sides, the superior ends of the fenestrations were in the jugular foramina. On the right side the fenestration had 3.8 cm length and was located in front of the transverse processes of the first two cervical vertebrae. On the opposite side the fenestration had 1.5 cm length and was antero-lateral to the transverse process of the atlas vertebra. On both sides the antero-medial arms of the fenestrations received the inferior petrosal sinuses and anterior condylar veins. Such highly placed fenestrations of the IJVs should be carefully documented either preoperatively, or prior to central venous access.

RESUMO

The number of infections related to cardiac implantable electronic devices (CIEDs) has increased as the number of devices implanted around the world has grown exponentially in recent years. CIED complications can sometimes be difficult to diagnose and manage, as in the case of lead-related infective endocarditis. We present the case of a 48-year-old male diagnosed with Staphylococcus aureus device-related infective endocarditis, 12 years after the implant of a single chamber pacemaker. A recent history of the patient includes two urinary catheterizations due to obstructive uropathy in the context of a prostatic adenoma, 2 months previously, both without antibiotic prophylaxis; no other possible entry sites were found and no history of other invasive procedures. After initiation of antibiotic therapy according to antibiotic susceptibility testing, we decided to remove the right ventricular passive fixation lead along with the vegetation and pacemaker generator; because of severe lead adhesions in the costoclavicular region, and especially in the right ventricle, we needed mechanical sheaths to remove the abundant fibrous tissue that encompassed the lead. After a difficult, but successful, lead extraction along with a large vegetation and 6 weeks' antibiotic therapy, the clinical and biological evolution was favorable, without reappearance of symptoms. While very late lead endocarditis is a rarity, late lead-related infective endocarditis (more than 12 months elapsed since implant) is not an exception; this is why we find that endocarditis prophylaxis should be reconsidered in certain patient categories, our patient being proof that procedures with neglectable endocarditis risk according to the guidelines can lead to bacterial endocarditis.

RESUMO

Persistence of the left superior vena cava (PLSVC) is a congenital anomaly reported in 0.3-0.5% of patients. Due to the multiple and complex anatomical variations, transvenous lead placement can become challenging. We report the case of a 47-year-old patient diagnosed with non-ischemic dilated cardiomyopathy with reduced left ventricular ejection fraction (LVEF-27%), who was referred to our clinic for implantation of a dual-chamber cardioverter defibrillator for primary prevention of sudden cardiac death. During the procedure we encountered an abnormal guidewire trajectory and after venographic examination we established the diagnosis of persistent left superior vena cava. After difficult implantation of a 7F defibrillation lead through the coronary sinus, we managed to place the atrial lead through a narrow brachiocephalic vein into the right atrial appendage. In this paper, we aim to illustrate the medical and technical implications of implanting a cardioverter defibrillator in patients with PLSVC, highlighting the benefit of identifying and utilizing both the innominate vein, and the left superior vena cava and coronary sinus for placement of multiple leads, which would otherwise have been impossible.

RESUMO

Osteoarticular tuberculosis (OATB) Aim: The authors made a clinical morphological assessment of tissue samples from patients admitted in Surgical Departments of the Emergency County Hospital of Craiova, Romania, between 1990 and 2015, proved as presenting tuberculous lesions of the spine in the Department of Pathology of the same Hospital. MATERIALS AND METHODS: The studied material consisted of bone, joint and sometimes muscle tissue fragments resulted from biopsies or surgical excisions from 7 cases coming out of 54 patients investigated in the above-mentioned period of time, where the established histological diagnosis was tuberculosis (TB). For diagnostic confirmation, Ziehl-Neelsen staining has been used as a rule but, in some cases, immunohistochemistry was also used. RESULTS: TB lesions have prevailed in men and around the age of 50 years. Thoracic segment of the spine was the most involved. Epithelioid and giant Langhans cells dominated the inflammatory cellular population. Necrosis was always present, usually in its classical acidophilic form. Fibrosis was almost always absent. On the whole, the granulomatous reaction was in almost half of the cases hyporeactive and disorganized. CONCLUSIONS: The clinical morphological profile of our series is fitting with data described in the literature. Because of its life threatening potential, spinal TB should be investigated thoroughly especially in its morphological features in order to obtain as quickly as possible an etiological diagnosis.

RESUMO

This study sought to characterize the developmental changes of three measures used to describe the morphology of the fetal cardiac vector: QRS peak-amplitude, QRS duration and QRS time-amplitude integral. To achieve this objective, we rely on a recently developed methodology for fetal cardiac vector estimation, using multichannel fetal magnetocardiographic (fMCG) recordings and realistic approximations of the volume conductors obtained from free-hand ultrasound imaging. fMCG recordings and 3D ultrasound images were obtained from 23 healthy, uncomplicated pregnancies for a total of 77 recordings performed at gestational ages between 22 and 37 weeks. We report the developmental changes of the cardiac vector parameters with respect to gestational age and estimated fetal weight, as well as their dependence on the estimated ventricular mass derived from cardiac dimensions measured with M-mode ultrasound. The normative values can be used along with the cardiac time intervals reported by previous fMCG studies to assist future clinical studies investigating conditions that affect fetal cardiac function.

RESUMO

RATIONALE: During the last decennium a more focused attention has been directed to the presence of chronic inflammation in cardiovascular diseases (CVD), but mainly to the high impact that this one has in generating and fastening the atherosclerotic process. OBJECTIVE: To highlight the causal relationship between periodontal diseases (PD) and CVD. One of the most important chronic inflammations, present in the modern societies in the vast majority of the population, is represented by the periodontal diseases (PD). Both types of diseases are characterized by a high and continuously increasing prevalence. It is now clear that they share some common risk factors, but it would be of great interest, not only for a scientific purpose, but also from a possible health benefit, as PD can be prevented and treated efficiently, to prove that there is a causal link between these two pathologies. METHODS: We will present a review of the actual data concerning their relationship. DISCUSSION: The study of this causal relationship is made more difficult due to the increased utilization, due to the guides' recommendations of the calcium antagonists (CA) in treating CVD.

RESUMO

Several studies in term and pre-term infants have investigated the rhythmic pattern of non-nutritive sucking (NNS) indicating correlations between the quantitative measures derived from sucking pressure variation and/or electromyographic (EMG) recordings and a range of factors that include age, perinatal stress and sequelae. In the human fetus, NNS has been reported from 13 weeks of gestation and has been studied using real-time Doppler ultrasonography exclusively. The present study indicates that NNS in fetus can be reliably recorded and quantified using non-invasive biomagnetic measurements that have been recently introduced as an investigational tool for the assessment of fetal neurophysiologic development. We show that source separation techniques, such as independent component analysis, applied to the high-resolution multichannel recordings allow the segregation of an explicit waveform that represents the biomagnetic equivalent of the ororhythmic sucking pressure variation or EMG signal recorded in infants. This enables the morphological study of NNS patterning over different temporal scales, from the global quantitative measures to the within burst fine structure characterization, in correlation with the fetal cardiac rhythm.

RESUMO

Fetal hiccups emerge as early as nine weeks post-conception, being the predominant diaphragmatic movement before 26 weeks of gestation. They are considered as a programmed isometric inspiratory muscle exercise of the fetus in preparation for the post-natal respiratory function, or a manifestation of a reflex circuitry underlying the development of suckling and gasping patterns. The present paper provides the first evidence of non-invasive biomagnetic measurements of the diaphragm spasmodic contractions associated with fetal hiccups. The magnetic field patterns generated by fetal hiccups exhibit well-defined morphological features, consisting of an initial high frequency transient waveform followed by a more prolonged low frequency component. This pattern is consistent across recordings obtained from two fetal subjects, and it is confirmed by signals recorded in a neonatal subject. These results demonstrate that fetal biomagnetometry can provide insights into the electrophysiological mechanisms of diaphragm motor function in the fetus. Additionally, we study the correlation between hiccup events and fetal cardiac rhythm and provide evidence that hiccups may modulate the fetal heart rate during the last trimester of pregnancy.

RESUMO

BACKGROUND: Dendritic cells (DCs) are potent antigen-presenting cells (APC) that are deeply implicated in the initiation and exacerbation of rheumatoid arthritis (RA). Active RA is associated with an activated DCs population as demonstrated by high expression of adhesion and co-stimulatory molecules. PURPOSE: To compare the expression of adhesion and co-stimulatory molecules on DCs from synovial tissue (ST) in patients (pts) with RA and the clinical status before and after treatment with disease modifying antirheumatic drugs (DMARDs). METHODS: Samples of ST were obtained from RA patients at the time of hip or knee replacement or arthroscopy. Clinical status (assessed by the American College of Rheumatology - ACR - core set and the DAS28) and co-stimulatory and adhesion molecules on DCs were evaluated before and after treatment. Immunophenotype of DCs was analyzed by two-color immunofluorescence microscopy. RESULTS: In patients with active RA we found a highly differentiated subpopulation of DCs that expressed an activated phenotype. After treatment, the expression of adhesion and co-stimulatory molecules on ST DCs was correlated with the ACR and DAS28 clinical response. CONCLUSION: Clinical outcome and the immunophenotypical presentation of ST DCs after DMARDs treatment are closely correlated in pts with RA. The co-stimulatory activity in the synovium is important in determining the course of the disease and provide new therapeutic targets for immune intervention.

RESUMO

BACKGROUND: Temporomandibular ankylosis with its multiple anatomo-clinical forms is a relatively rare disease. Its major morphopathological, therapeutical and psychological implications rank it among severe illnesses. Its treatment is exclusively surgical. The major therapeutical indication in ankylosis of type I and II Topazian is the neoarticular modelling osteotomy with interposition. MATERIAL AND METHODS: As a material for interposition, over the last 7 years, we have used in 15 patients with 18 ankylosis, concave rectangular Dacron fragments adequately shaped after being taken from a vascular prothesis. RESULTS: The qualities of this material are confirmed by the obtained results: quick resuming of the normal mobility of the mandible, lack of postoperative complications and recurrences. The material is cheap and easy to be obtained. The technique to be used is simple. DISCUSSION: The Dacron texture is soft, elastic in all respects, thick enough, resistant, with long lasting elasticity and integrity, physically and chemically sTable, well tolerated by the body and without foreign body rejection. It is easy to be cut, shaped, modelled and adapted to the bone stump. It is sterilized by autoclaving. It is also well integrated into the host tissue being penetrated by the connective tissue which fastens it to the surface of the neocondyle preventing a relapse. It plays the role of a joint cartilage.

RESUMO

During the past two decades new methods and techniques for the treatment of middle floor facial fractures have been developed. The orthopedic approach alone or associated with various procedures of internal suspension gradually became obsolete. Nowadays, a successful treatment implies the early surgical exploration and a careful restoration of bone skeletal structure. Osteosynthesis with mini-plates provides for the reduction and tridimensional stability of bone fragments. Moreover, in the communicative fractures and in those accompanied by substance loss, the titanium mini-plates are the best method for the immediate fixation of bone grafts.

RESUMO

The analysis in based on 12,096 patients with fractures of the mandible admitted to and treated in the Clinical of Oral and Maxillofacial Surgery of Iasi in the interval 1951-1995. Posttreatment complications were found in 10.52% of the cases, 9.81% of them being of inflammatory type. Anatomo-clinically these consisted in suppurations of the soft tissues, osteitis and osteomyelitis. The prejudices caused by these complications were multiple: longer hospital stay, additional suffering for the patient, temporary work inability, higher treatment costs.

RESUMO

By testing 2362 children and infants from Craiova (Romania), for both HIV-antibody and HBs-antigen presence in the blood, a high rate of positivity was noticed in orphanages and in dystrophia units. A rate of "signal" (i.e. about 4% for HIV-antibodies, and 2.5% for HIV-antibody/HBs antigen), in hospitalized patients (pediatric service), was found as well. Four reasons support the horizontal way of virus transmission as the main route: most of seropositive subjects belong to 1-to-3-year age range, suggesting a virtual contamination before introduction of disposable syringes in Romania care units and hospitals; many HIV-seropositive cases have received frequent parenteral treatments, during repeated hospitalizations for acute respiratory disease; only few of the mothers of seropositive infants exhibited HIV-antibody presence; a relatively high rate of "double" seropositivity, i.e. HIV-antibody/HBs antigen, within tested serum samples was noticed.

RESUMO

The study included 359 cases of primary tuberculosis (benign forms) in children aged 0-14 years, out of which 181 non-complicated and 178 complicated forms. The therapeutical regimens were: 3HEZ2/3HE2 (study subgroup) and 6HE2/3H2 (control) for non-complicated forms, and 3HRZ2/3HR2 (study subgroup) and 3HES2/3HE2/3H2 (control) for complicated ones. Late results (5 years after treatment end) were very good (from clinical, radiological, bacteriological points of view) in 100% of cases. Thus, short-course regimens are preferable to longer ones (over 6 months) in the chemotherapy of the benign forms of pulmonary tuberculosis in children.

RESUMO

In 6 cases of tumors, two gigantic benign and four malignant in T4 having palatal and gingivo-alveolar starting point with invasive evolution into the structure of facial mass, surpassing the median alignment, the authors consider the problem concerning the indications for exeresis, possibilities of removal of healthy tissue and the reconstruction of massive losses of substance. The surgical treatment of reconstruction that completes the exeresis of the tumor is meant to sustain the ocular globe through a aponeurotic-muscular flap form the temporal muscle, with the aid of nasal septum or a skin graft also used to obtain a good coating of the cavity, and is also meant to a plastic reconstruction of the soft palate as well as to retention modelling of the cavity fields which resulted postsurgically. The main role in maxillofacial reconstruction in held by the obturator prosthesis that avoids morphofunctional prejudices and restores facial contour, without aesthetic and psychic prejudices. The results obtained in our 6 cases shown here have been fully satisfactory.
