RESUMO

Enchondromas are benign tumors located primarily in long bones, some of which can be accidentally discovered during imaging exams conducted for other pathologies. These benign cartilaginous tumors are hard to differentiate from low grade chondrosarcomas, which require periodic follow ups. The purpose of this study was to identify the incidence of enchondromas in pediatric patients, to determine medical imaging criteria (Computed Tomography-CT and Magnetic Resonance Imaging-MRI) in order to differentiate enchondromas from other atypical cartilaginous tumors, and to identify a potential correlation between imaging aspects and clinical signs. The aim of this study was to review imaging findings of enchondromas in children.

RESUMO

This review highlights oral anomalies with major clinical impact in Addison disease (AD), including dental health and dermatologic features, through a dual perspective: pigmentation issues and AD comorbidities with oral manifestations. Affecting 92% of AD patients, cutaneomucosal hyperpigmentation is synchronous with or precedes general manifestations by up to a decade, underlying melanocytic infiltration of the basal epidermal layer; melanophages in the superficial dermis; and, rarely, acanthosis, perivascular lymphocytic infiltrate, and hyperkeratosis. Intraoral pigmentation might be the only sign of AD; thus, early recognition is mandatory, and biopsy is helpful in selected cases. The buccal area is the most affected location; other sites are palatine arches, lips, gums, and tongue. Pigmented oral lesions are patchy or diffuse; mostly asymptomatic; and occasionally accompanied by pain, itchiness, and burn-like lesions. Pigmented lingual patches are isolated or multiple, located on dorsal and lateral areas; fungiform pigmented papillae are also reported in AD individuals. Dermoscopy examination is particularly indicated for fungal etiology; yet, it is not routinely performed. AD's comorbidity burden includes the cluster of autoimmune polyglandular syndrome (APS) type 1 underlying AIRE gene malfunction. Chronic cutaneomucosal candidiasis (CMC), including oral CMC, represents the first sign of APS1 in 70-80% of cases, displaying autoantibodies against interleukin (IL)-17A, IL-17F ± IL-22, and probably a high mucosal concentration of interferon (IFN)-γ. CMC is prone to systemic candidiasis, representing a procarcinogenic status due to Th17 cell anomalies. In APS1, the first cause of mortality is infections (24%), followed by oral and esophageal cancers (15%). Autoimmune hypoparathyroidism (HyP) is the earliest endocrine element in APS1; a combination of CMC by the age of 5 years and dental enamel hypoplasia (the most frequent dental complication of pediatric HyP) by the age of 15 is an indication for HyP assessment. Children with HyP might experience short dental roots, enamel opacities, hypodontia, and eruption dysfunctions. Copresence of APS-related type 1 diabetes mellitus (DM) enhances the risk of CMC, as well as periodontal disease (PD). Anemia-related mucosal pallor is related to DM, hypothyroidism, hypogonadism, corresponding gastroenterological diseases (Crohn's disease also presents oral ulceration (OU), mucogingivitis, and a 2-3 times higher risk of PD; Biermer anemia might cause hyperpigmentation by itself), and rheumatologic diseases (lupus induces OU, honeycomb plaques, keratotic plaques, angular cheilitis, buccal petechial lesions, and PD). In more than half of the patients, associated vitiligo involves depigmentation of oral mucosa at different levels (palatal, gingival, alveolar, buccal mucosa, and lips). Celiac disease may manifest xerostomia, dry lips, OU, sialadenitis, recurrent aphthous stomatitis and dental enamel defects in children, a higher prevalence of caries and dentin sensitivity, and gingival bleeding. Oral pigmented lesions might provide a useful index of suspicion for AD in apparently healthy individuals, and thus an adrenocorticotropic hormone (ACTH) stimulation is useful. The spectrum of autoimmune AD comorbidities massively complicates the overall picture of oral manifestations.

RESUMO

In the pathogenesis of chronic periodontitis, there are general systemic factors which play a major role, such as osteoporosis, with menopause as the most common etiological factor, and other pathological determining conditions for osteoporosis as well (ovary, thyroid and malignant tumors). The aim of the present study was to assess the correlations between periodontal indices and osteoporosis. The study was performed on 35 patients with periodontal disease aged between 45 and 79 years. These patients were divided into two groups: a study group with osteoporosis and periodontal disease (n=25) and a control group with periodontal disease (n=10) only. The periodontal assessment included community periodontal index (CPI), gingival inflammation index (GI), plaque index (PI), body mass index (BMI), bone mineral density (BMD), tooth mobility and tooth loss. Osteoporosis was assessed by dual-energy X-ray absorptiometry. Results were statistically analyzed with Microsoft Excel software and XLSTAT. The results showed that patients in the study group had higher values of periodontal indices, and a highly significant inverse correlation was observed between the CPI and the tooth loss. Inverse correlations between BMI and tooth mobility, as well as BMI and CPI were determined for the study group. In conclusion, the positive association between BMD and GI shows that the gingival index can be a predictive factor in the occurrence of osteoporosis.

RESUMO

Osteochondroma represents a bone outgrowth covered by cartilaginous tissue and localized on the external surface of the bone. The incidence of osteochondroma is 20-35% of all pediatric benign tumors. Osteochondromas can be present in solitary or multiple forms and usually occur in the metaphysis of long bones in immature skeletons. The present study aimed to retrospectively determine the association between imaging diagnostic accuracy and histopathological examinations, which are the main methods of diagnosis for this type of tumor. A total of 66 patients presenting with radiological aspects of osteochondroma were initially selected; however, only the 56 patients who had a positive histopathological diagnosis of osteochondroma were eventually included in this study. Patient characteristics were taken into consideration and included age, sex, lesion localization, lesion imaging semiotics and histopathological aspects. Osteochondromas are generally asymptomatic lesions that are often incidentally diagnosed after trauma, which makes it difficult to determine the exact incidence of this pathology.

RESUMO

Turner syndrome (TS) is characterized by partial or complete loss of a sexual chromosome, resulting in an incomplete development of the body, gonadic failure, cardiac and renal abnormalities, oro-dental changes, etc. In our study, we proposed to perform a histological and immunohistochemical (IHC) study of the periodontium changes in patients with TS. The biological material under study was represented by fragments of gingival mucosa harvested from 18 patients with TS who presented advanced periodontal lesions and required dental extractions. The fragments of gingival mucosa were processed by the classical histological technique of paraffin inclusion, subsequently the obtained sections being stained by the Hematoxylin-Eosin (HE) and examined under the optical microscope. For the IHC study, there were performed serial sections incubated with anti-cluster of differentiation (CD) 3, anti-CD20 and anti-CD68 antibodies for highlighting immune cells, as well as with anti-matrix metalloproteinase (MMP) 2 and anti-MMP8 antibodies for highlighting MMPs (MMP2 and MMP8) involved in the periodontal tissue lesions. In the present study, during the histological examination, there were observed morphological changes, both in the epithelium and in the gingival mucosa chorion. Epithelial changes consisted in the onset of acanthosis processes, in the thickening of the epithelium due to the increase of the spinous layer, as well as in the parakeratosis phenomenon. In the chorion, there was observed the presence of inflammatory infiltrates in various stages, presence of fibrosis (extended in some cases) and the presence of an important vascularization in some cases, with a high number of immunocompetent cells involved in the inborn immune response, but also in the adaptive one, as well as a more or less intense immunoexpression of MMP2 and MMP8. Our study suggests that TS may contribute to the development of some inflammatory processes in the marginal periodontium.

RESUMO

Fetus in fetu (FIF) is a rare entity, with a difficult preoperative diagnosis, frequently being an intraoperative surprise. In recent literature, theories pertaining to its development either assimilate the tumor with a monochorionic twin that halted its evolution, or with a highly differentiated mature teratoma. We present the case of a 27-year-old patient, with a cystic tumor in the anterior mediastinum, which intraoperatively proved to be a rare case of intrathoracic FIF. The clinical presentation lacked any specific clues that would infer such a diagnosis; imaging was partially useful as it shown the possible existence of bone structures, heterogeneously mixed with fatty inclusions and other types of tissue. Upon surgery, the nature of said tumor was clear, and pathology confirmed the FIF diagnosis, showing different types of epithelia and tissue of several organ-like structures that halted in evolution at an early stage. Concluding our presentation, we can say that the presence of an axial skeleton as well as differentiated tissue types of several organs could confirm our case of FIF.

RESUMO

Renal metastases are uncommon in clinical practice, even as autopsy reports much frequent cases în disseminated tumors. Usually multiple and bilateral, they can determine many problems of differential diagnosis in case of solitary renal mass, when a primary kidney neoplasm must be excluded. Main sources are represented by the tumors of the lung, breast, digestive tract, melanomas and lymphomas, but rare cases with other etiology have been reported. Imaging can help to the diagnosis; CT scan, MRI, transabdominal ultrasound and sometimes contrast enhanced ultrasound can be useful. The treatment is individualized by the general status, by other organs involved and by the control of primary tumors; nephrectomy can be made in cases with unsure diagnosis and if primary tumor is controlled.

RESUMO

The aim of the study was to investigate the potential of sildenafil and tadalafil to ameliorate structural kidney damage in contrast-induced nephropathy (CIN). A rat model of CIN was developed by dehydration, administration of a nitric oxide inhibitor and a prostaglandin synthesis inhibitor (L-NAME/indomethacin) and contrast media exposure to iopromide. The effect of pre-treatment with sildenafil, tadalafil or N-acetyl cysteine (NAC) for 7 days prior to CIN induction was investigated. All animals were sacrificed at 24 h after CIN induction and both kidneys were collected. Histopathological examination was performed under light microscopy in serial tissue sections stained with hematoxylin and eosin. CIN group showed hydropic changes of the renal tubules (proximal and distal convoluted tubules and Henle's loop), an increased Bowman space with lobulated glomerulus and alteration of macula densa region of distal convolute tubules. The groups pretreated with sildenafil and tadalafil showed nearly normal histological aspects of renal tissue. The group pretreated with NAC showed similar but less intense histopathologic changes compared to CIN group. Sildenafil and tadalafil pre-treatment ameliorates CIN-related structural kidney damage and the protective potential of these agents is superior to NAC.

RESUMO

The new outbreak of coronavirus from December 2019 has brought attention to an old viral enemy and has raised concerns as to the ability of current protection measures and the healthcare system to handle such a threat. It has been known since the 1960s that coronaviruses can cause respiratory infections in humans; however, their epidemic potential was understood only during the past two decades. In the present review, we address current knowledge on coronaviruses from a short history to epidemiology, pathogenesis, clinical manifestation of the disease, as well as treatment and prevention strategies. Although a great amount of research and efforts have been made worldwide to prevent further outbreaks of coronavirus­associated disease, the spread and lethality of the 2019 outbreak (COVID­19) is proving to be higher than previous epidemics on account of international travel density and immune naivety of the population. Only strong, joint and coordinated efforts of worldwide healthcare systems, researchers, and pharmaceutical companies and receptive national leaders will succeed in suppressing an outbreak of this scale.

RESUMO

Owing to its continuous transformation, the musculoskeletal system of pediatric patients presents some unique features with respect to both anatomy and physiology. The lesional pattern of the knee in pediatric patients is both similar to and in many aspects different from the lesional pattern in adults with knee injuries. In the case of pediatric patients, meniscal, tendinous and ligamentous lesions occur most frequently as a consequence of traumatic episodes. The purpose of the present study is to emphasize the importance of MRI examinations in pediatric patients exhibiting symptoms of knee joint injury. The imaging assessment of the extent of the lesions, which can be either simple or complex alterations, can directly influence the clinical management of these cases by appreciating the growth potential of the specific segment of immature skeleton involved.

RESUMO

The aim of the study was to evaluate the potential protective role of sildenafil and tadalafil in contrast-induced nephropathy (CIN) by modulating oxidative stress. Thirty Wistar male rats were equally assigned into five groups: sham, CIN, CIN + sildenafil (10 mg/kg bw/day), CIN + tadalafil (5 mg/kg bw/day) and CIN + N-Acetyl Cysteine (NAC) (100 mg/kg bw/day) as a positive control. CIN was induced by 12 h dehydration and administration of indomethacin (10 mg/kg bw), N-ω- nitro-L-arginine methyl ester (10 mg/kg bw), and iopromide (3 g/kg bw iodine). Blood was drawn prior to and 24 h after CIN induction for evaluating renal function and oxidative stress. In the CIN group, total antioxidant capacity (TAC), reduced glutathione (GSH) and catalase (CAT) levels were significantly decreased; and protein carbonyl (PROTC) and thiobarbituric reactive species (TBARS) were significantly increased compared to the sham group. Pre- Sildenafil and tadalafil pre-treatment reduced CIN risk and reversed oxidative stress almost to the sham group levels. These results suggest that PDE5Is can be good candidates for preventing CIN based on their ability to modulate the oxidant/antioxidant balance.

RESUMO

Craniofacial and dental morphology is influenced by different circulating hormones, but it is of particular importance that there is growth hormone (GH) in normal craniofacial and teeth development. Craniofacial morphometry studies in children with GH deficiency show different changes in certain anthropometric variables in the sense of reducing their values compared to normal children's developmental norms in different stages of childhood and adolescence. Therefore, the early establishment of GH replacement therapy can correct craniofacial morphological changes induced by GH deficiency. In our study, we evaluated different anthropometric craniofacial variables at children with GH deficiency and we established some anthropometric and morphological characteristics associated with this pathology.

RESUMO

The present study focused on the assessment of the inflammatory infiltrate that characterizes nasal polyps in patients with chronic rhinosinusitis and nasal polyposis. Inflammatory cell type was determined using specific markers. This evaluation was made possible by determining the expression of the following markers: CD20, a marker of B lymphocytes [using activated T cells (ATC) armed with CD20 antibody]; CD3, a marker of T lymphocytes (using ATC armed with anti­CD3 antibody); CD45, the leukocyte common antigen (using ATC armed with anti­CD45 antibody; and CD34, for the microvasculature of the nasal polyp (using anti­CD34 antibody). The diagnosis of chronic rhinosinusitis with nasal polyps (CRSwNP) was made according to current EPOS guidelines based on patient history, clinical examination and nasal endoscopy. We examined surgically resected nasal polyps from 127 patients diagnosed with CRSwNP, who benefited from surgical procedures at the Department of Otorhinolaryngology of our institution. The polyps were analyzed at the Department of Pathology of our institution utilizing histopathological and immunohistochemical methods as follows: Firstly, the tissues were paraffin­impregnated, sectioned and stained with hematoxylin and eosin. We then examined the expression of CD3, CD20, CD34 and CD45RO by immunohistochemistry with soluble labeled streptavidin biotin (LSAB)/horseradish peroxidase (HRP) complexes. We observed the following histopathological changes: The structure of the epithelium was evidenced by collagenous subjacent stroma with mixed areas, sometimes associated with hyaline zones. In all types of polyps, we also observed a diffuse underlayer or periglandular lymphoplasmacytic in filtrate composed predominantly from T lymphocytes and eosinophils. The histopathological changes suggest the chronic inflammation of the sinus mucosa, which was diffusely distributed in allergic polyps and with nodular distribution in fibro­inflammatory polyps. The number of B lymphocytes was greater in the fibro­inflammatory polyps. On the whole, the findings of this study indicate that the inflammatory infiltrate in nasal polyps from patients with CRSwNP is mainly composed of T cells and eosinophils in all types of polyposis. In addition, a diffuse distribution of allergic polyps and the nodular distribution of fibro­inflammatory polyps, and the hyperplasia of the seromucous glands was observed. The determination of CD20, CD3, CD34 and CD45RO could be used to assess the inflammatory infiltrate of the nasal poplyps in these patients.

RESUMO

Contrast agents are used in radiology to increase the sensibility and specificity of radiological techniques. Some of these compounds have side effects that include organ toxicity (with kidney being the most affected organ) and hypersensitivity reactions. We performed multiple PubMed searches from January, 2008 to January, 2018 for studies regarding adverse reactions to compounds used as contrast agents in imagistic techniques. The initial research identified 929 records written in English. After further excluding 223 non-human studies, 292 articles that had irrelevant designs as reviews, meta-analysis, commentaries, editorials and case reports, 414 studies were selected for retrieval. After reading the abstracts, we excluded 363 studies as they had little relevance to the study. In total, 51 full-articles were assessed for eligible studies to be included. Finally, 20 articles were included in the analysis. In our systematic literature search the incidence of overall skin immediate reactions to iodinated contrast media (ICM) had an incidence between 1.15 and 0.12%, depending on the cohort analyzed in the studies. The percentage of cutaneous manifestations in the cohort that experienced immediate hypersensitivity reactions was between 33.33 and 87.7%. The most frequent skin manifestations were urticaria, rashes, pruritus and limited facial edema. Non-iodinated contrast agents have a safer profile compared with ICM, the incidence of immediate adverse reactions being very low in gadolinium-based contrast agents and other agents used for contrast-enhanced ultrasound. The incidence of delayed reactions was between 10.1 and 0.03%. In the studies analyzed by us the main adverse reactions due to delayed hypersensitivity phenomena were cutaneous manifestations that were present between 70.27 and 100% of the cases. Regarding the risk factors for developing immediate adverse reactions, being female was a predisposing factor accompanied by history of allergy and history of reactions to contrast media. An accurate anamnesis of the patients and a correctly conducted pretreatment can limit the incidence and the severity of the adverse reactions and also can avoid the life occurrence of life-threatening reactions.

RESUMO

In the present study, we highlight the types of anxiety and the coping strategies employed by the students at the Medicine, Pharmacy and Nursing Faculties, at the same time comparing them with the general population. This research involved 333 first year students, 18-20 years of age. We used the Endler Multidimensional Anxiety Scales-Trait (EMAS-T) and Social Anxiety Scale-Trait (SAS-T) and two coping measuring instruments, Cognitive Emotion Regulation Questionnaire (CERQ) and Strategic Approach to Coping Scale (SACS). We obtained an overview on the hierarchy of the types of anxiogenic situations for the study participants, by gender and specialization. We analyzed and discussed the correlations between anxiety and coping and we discussed the results of the factor analysis. We noticed the students' predilection for maladaptive coping mechanisms and how anxiety relates to their professional choice.

RESUMO

Most percutaneous vertebroplasty procedures are being performed in order to relieve pain in patients with severe osteoporosis and associated stable fractures of one or more vertebral bodies. In addition, vertebroplasty is also recommended for patients suffering from post-traumatic symptoms associated with vertebral fractures, patients with large angiomas positioned inside the vertebral body, with an increased risk for collapse fracture and also patients presenting with pain associated with vertebral body metastatic disease. On another aspect, it is possible that in isolated cases, an orthopedic surgeon confronted with a vertebra plana presentation will recommend bone cement injection into the vertebral bodies adjacent to the fractured one, in order to have a better and more robust substrate for placement of screws or other fixation devices. The aim of our study is to compare results attained by the Department of Interventional Radiology, in performing this procedure, with results attained by following the classical orthopedic treatment procedure, involving non-operative treatment, using medication and bracing varying from simple extension orthoses in order to limit spinal flexion, light bracing for contiguous fractures, presenting either angulation or compression, and for severe cases standard thoracolumbosacral orthoses (TLSOs).

RESUMO

The Herlyn-Werner-Wunderlich syndrome (HWWS) is a complex congenital malformation, originally described as a triad of symptoms: didelphys uterus, low genital obstruction and unilateral renal anomaly. The term OHVIRA is an acronym (obstructed hemivagina/hemicervix with ipsilateral renal anomaly) and refers to the same syndrome. It gained acceptance in recent years, due to reports of cases having a non-didelphys uterus (normal, septated or having other abnormalities). In the following, we report two cases with good pregnancy outcome and we provide a short discussion on published literature. We highlight differences and complications in these two cases, confirming the extreme variability of anatomic structures involved in the syndrome. Though rare, the condition allows successful pregnancies. We describe the sixth case of didelphys uterus with unique (anatomically normal) vagina and unilateral isolated hemicervix hypoplasia∕atresia. Imaging has a paramount importance in the diagnosis of HWWS∕OHVIRA, with magnetic resonance (MR) usually superseding the ultrasound (US) method, and providing other viscera details. US, MR and laparoscopy∕laparotomy complement each other, and for describing the anatomy of the obstruction a thorough clinical examination is required. The clinical course of the pathology is not standard and the management must be tailored, but term∕near-term pregnancies resulting in healthy newborns are possible in HWWS. We advocate an appropriate maternal and fetal prenatal care and long-term follow-up.

RESUMO

Muscular metastases are rarely found in medical practice, and the reported cases in literature are not numerous. The diagnosis of these lesions involves an interdisciplinary collaboration. We present a case of secondary determination in the psoas muscle, with a starting point of cervical squamous carcinoma. In establishing the diagnosis, there contributed the clinical, imagistic and magnetic resonance evaluation and computed tomography (CT), the histopathological diagnosis being determined after the CT-guided biopsy puncture.

RESUMO

The pleomorphic adenoma is the most frequently encountered tumor of the salivary glands, representing between 45% and 75% of the total number of the tumors of the salivary glands. According to the literature, there are many studies on the immunohistochemical aspects of the myoepithelial cells, present in the pleomorphic adenoma of the salivary gland. A big diversity of mono and polyclonal antibodies, such as the cytokeratins, muscular proteins and other markers, has been used. In our study, we investigated the immunohistochemical aspect of bone morphogenetic protein 6 (BMP6) marker concerning 15 cases of pleomorphic adenomas of the salivary glands. In the immunohistochemical study, we used the paraffin blocks that served for obtaining the sections necessary for the classical histopathological processing by means of the usual stainings. The immunohistochemical study used the enzymatic detection and the LSAB 2 (Labeled Streptavidin-Biotin 2) System technique as the working method. In order to underline the process of epithelial-mesenchymal transition, we also used double sequential immunohistochemical reactions. By the use of the BMP6 marker, we intended to evaluate the reactivity of the various tumor components in the pleomorphic adenomas of the salivary gland, for this marker, taking into consideration its possible involvement in the process of the epithelial-mesenchymal transition. The maximum reactivity for BMP6 was recorded at the level of the normal, excretory, intratubular units, in the luminal cells of the proliferative ductal units, in the myxoid matrix, the cytoplasm of the myxoid stellate cells and the plasmacytoid matrix and the cytoplasm of the chondroid lacunar cells. Some of the cells belonging to the solid, proliferative areas, some of the abluminal cells, that are part of the proliferative ductal units and certain myxoid stellate or plasmocytoid cells contain the S100 protein, which would indicate the existence of some processes of mesenchymal epithelial÷myoepithelial transdifferentiation in the development of this type of salivary tumor. The BMP6 expression is specific to the serous acini salivary cells, which are the most specialized epithelial salivary gland cells. The study demonstrated that the mesenchymal epithelial÷myoepithelial potential of transdifferentiation of the luminal cells that make up the proliferative units is certified by the immunohistochemical expression of some BMP6 purely mesenchymal protein cells.

RESUMO

The procoagulant status of neoplastic patients is well known in medical literature, but in the last years there is attempted a correlation between the histological types of neoplasia and the risk for thrombotic strokes. We present the case of a 44-years-old patient undergoing early menopause, who was diagnosed with cervical tumor of the serous adenocarcinoma type. The patient underwent external radiotherapy, and, in the seventh day of treatment, she suffered a frontal-temporal-parietal ischemic stroke with left hemiplegia. The blood testing highlighted procoagulant products (double fibrinogen compared to normal values, deficit of antithrombin and a high number of thrombocytes). The patient received neurological and rehabilitation treatment, at first with Heparin, followed by the administration of an antiaggregant. During this treatment, the deficit remained unchanged. She continued the neurological and rehabilitation treatment, followed by radiotherapy, with a good evolution. Six months after the stroke, it was decided the surgical tumor ablation of cytoreduction. The post-surgery histological examination highlighted specific changes due to post-surgery radiotherapy, without the presence of any neoplastic cells. The imagistic evaluation, computed tomography (CT) every three months after surgery, did not highlight any suggestive dissemination elements. The occurrence of an ischemic stroke in a patient with endocervical neoplasm of the adenocarcinoma type during radiotherapy imposed the discharge of chemotherapy, with subsequent imaging, biological and histopathological monitoring after surgery. The cause of stroke in this case is determined by the hypercoagulant status in the context of the developed neoplasia, the patient being free of any other risk factors.
