RESUMO
ABSTRACT Objective: To evaluate the results of percutaneous vertebroplasty (PV) in spinal fragility fractures (osteoporosis/tumor), analyzing possible complications. Method: We evaluated 33 patients with spinal fractures (FXV) due to osteoporosis or tumor who underwent PV between January and November 2021. A physical examination was performed, obtaining the history and risk factors for bone fragility/tumor and a radiological evaluation of the spine to verify FXV. Genant's semiquantitative method was used for postoperative classification, the VAS score, and a disability questionnaire (ODI). A radiologist evaluated tomographic control to quantify vertebral filling and extravasation, determining where they occurred. Results: 46 vertebrae of 33 patients were operated on, with a mean age of 71 years, and 11 patients with more than one level of surgery. Of the total, 13 patients had tumor fractures, and 20 had fractures due to insufficiency. PMMA extravasation was observed in 31 vertebrae, most frequently in the External Vertebral Venous Plexus (23), Discal Body (9), Anterior Epidural Recess (4), Pulmonary Vessels (4), Internal Vertebral Venous Plexus (3), Inferior Cava (2), Adipose Plane (2) and Azygos Vein (1). No patient had clinical complications. Furthermore, the mean preoperative VAS was eight, the postoperative one was 3, the mean preoperative ODI was 56, and the postoperative one was 30. Conclusion: PMMA extravasation was frequent in several locations and levels without any clinical complications. VP proved to be effective in improving pain and function. Level III; Longitudinal Retrospective Cohort Study.

PURPOSE: Changes in cerebral cortical regions occur in HIV-infected patients, even in those with mild neurocognitive disorders. Working memory / attention is one of the most affected cognitive domain in these patients, worsening their quality of life. Our objective was to assess whether cortical thickness differs between HIV-infected patients with and without working memory deficit. METHODS: Forty-one adult HIV-infected patients with and without working memory deficit were imaged on a 1.5 T scanner. Working memory deficit was classified by composite Z scores for performance on the Digits and Letter-Number Sequencing subtests of the Wechsler Adult Intelligence Scale (third edition; WAIS-III). Cortical thickness was determined using FreeSurfer software. Differences in mean cortical thickness between groups, corrected for multiple comparisons using Monte-Carlo simulation, were examined using the query design estimate contrast tool of the FreeSurfer software. RESULTS: Greater cortical thickness in left pars opercularis of the inferior frontal gyrus, and rostral and caudal portions of the left middle frontal gyrus (cluster 1; p = .004), and left superior frontal gyrus (cluster 2; p = .004) was observed in HIV-infected patients with working memory deficit compared with those without such deficit. Negative correlations were found between WAIS-III-based Z scores and cortical thickness in the two clusters (cluster 1: ρ = -0.59; cluster 2: ρ = -0.47). CONCLUSION: HIV-infected patients with working memory deficit have regions of greater thickness in the left frontal cortices compared with those without such deficit, which may reflect increased synaptic contacts and/or an inflammatory response related to the damage caused by HIV infection.

OBJECTIVE: To evaluate the impact of orthognathic surgery on quality of life (QoL) and to compare single- and double-jaw surgeries in terms of ratio and patient perceptions of the postoperative period. STUDY DESIGN: A prospective, longitudinal observational study was conducted. The short form Oral Health Impact Profile (OHIP-14) and the Orthognathic Quality of Life Questionnaire (OQLQ) were applied preoperatively and 6 months postoperatively to evaluate oral health-related QoL (OHRQoL). Additionally, patient perceptions of the immediate postoperative period were assessed at the first and fourth week after surgery. RESULTS: One hundred consecutive patients were recruited and assigned to the single-jaw group (n = 24) or the double-jaw group (n = 76) according to the characteristics of each facial or occlusal deformity. The questionnaires showed lower scores for both groups after surgery, indicating significant benefits to OHRQoL. The whole sample OHIP-14 mean total scores decreased from 10.5 to 2.8 (P < .001, d = 1.35), whereas OQLQ showed a decrease from 48.4 to 11.6 (P < .001, d = 1.75). CONCLUSIONS: Orthognathic surgery can improve OHRQoL, and long-term benefits outweigh the risks and discomfort associated with the treatment.

OBJECTIVE: To identify predictors of death in the Intensive Care Unit and relate eligible patients to preferential palliative care. METHOD: A prospective cohort study that evaluated patients hospitalized for more than 24 hours, subdivided into G1 (patients who died) and G2 (patients who were discharged from hospital). For identifying the predictors for death outcome, the intensivist physician was asked the "surprise question" and clinical-demographic data were collected from the patients. Data were analyzed by descriptive/inferential statistics (p<0.05 significance). RESULTS: 170 patients were evaluated. The negative response to the "surprise question" was related to death outcome. A greater possibility of death (p<0.05) was observed among older and more frail patients with less functionality, chronic cardiac and/or renal insufficiencies or acute non-traumatic neurological insult, with multiorgan failure for more than 5 days, and hospitalized for longer. CONCLUSION: Predictors of death were related to a subjective evaluation by the physician, the clinical condition of the patient, underlying diseases, the severity of the acute disease and the evolution of the critical illness. It is suggested that patients with two or more predictive criteria receive preferential palliative care.

Purpose Despite antiretroviral therapy, approximately half of individuals with human immunodeficiency virus (HIV) will develop HIV-associated neurocognitive disorder (HAND). Efficiency of brain networks is of great importance for cognitive functioning, since functional networks may reorganize or compensate to preserve normal cognition. This study aims to compare efficiency of the posterior cingulate cortex (PCC) between patients with and without HAND and controls. We hypothesize HAND negative (HAND-) patients will show higher PCC efficiency than HAND positive (HAND+) patients. Methods A total of 10 HAND + patients were compared with 9 HAND- patients and 17 gender-, age-, and education-matched controls. Resting-state functional MRI was acquired with a 3 Tesla scanner. Local efficiency, a measure of network functioning, was investigated for PCC. Network differences among HAND + , HAND- patients and controls were tested as well as correlations between network parameters and cognitive test performance in different domains. Results HAND- patients showed significantly increased PCC efficiency compared with healthy controls ( p = 0.015). No differences were observed between HAND + patients and either controls ( p = 0.327) or HAND- patients ( p = 0.152). In HAND- patients, PCC efficiency was positively related with cognitive performance in the attention/working memory domain ( p = 0.003). Conversely, in HAND + patients, PCC efficiency was negatively correlated with performance in the abstraction/executive domain ( p = 0.002). Conclusion HAND- patients showed a higher level of PCC efficiency compared with healthy subjects, and PCC efficiency was positively related to cognitive performance. These results support the functional reorganization hypothesis, that increased PCC efficiency is a compensation technique to maintain cognitive functioning.

RESUMO Objetivo Identificar preditores de óbito na Unidade de Terapia Intensiva e relacionar pacientes elegíveis para cuidados paliativos preferenciais. Método Coorte prospectivo que avaliou pacientes internados por mais de 24 horas, subdivididos em G1 (pacientes que morreram) e G2 (pacientes com alta hospitalar). Para a identificação dos fatores preditores para o desfecho óbito, foi feita ao médico intensivista a "pergunta-surpresa" e foram coletados dados clínico-demográficos dos pacientes. Os dados foram analisados por estatística descritiva/inferencial (significante p<0,05). Resultados Foram avaliados 170 pacientes. A resposta negativa à "pergunta-surpresa" foi relacionada ao desfecho óbito. Houve maior possibilidade de óbito (p<0,05) entre os pacientes mais velhos, mais frágeis, com menor funcionalidade, com insuficiências cardíaca e/ou renal crônicas ou insulto neurológico agudo não traumático, com falência multiorgânica por mais de 5 dias, internados por mais tempo. Conclusão Preditores de óbito foram relacionados à avaliação subjetiva do médico, à condição clínica do paciente, às doenças de base, à gravidade da doença aguda e à evolução da doença crítica. Sugere-se que pacientes com dois ou mais critérios preditores recebam cuidados paliativos preferenciais.

PURPOSE: To longitudinally evaluate the cortical thickness and deep gray matter structures volume, measured from T1 three-dimensional (3D) Gradient echo-weighted imaging, and white matter integrity, assessed from diffusion tensor imaging (DTI) of HIV-positive patients. MATERIALS AND METHODS: Twenty-one HIV-positive patients on stable highly active antiretroviral therapy (HAART) with CD4+ T lymphocytes count >200 cells/mL and viral load <50 copies/mL underwent two magnetic resonance imaging (MRI) scans with a median interval of 26.6 months. None of the patients had HIV-related dementia. T1 3D magnetization prepared rapid gradient echo-weighted imaging and DTI along 30 noncolinear directions were performed using a 1.5 Tesla MR scanner. FreeSurfer was used to perform cortical volumetric reconstruction and segmentation of deep gray matter structures. For tract-based spatial statistics analysis, a white matter skeleton was created, and a permutation-based inference with 5000 permutations, with a threshold of P < 0.05 was used to identify abnormalities in fractional anisotropy (FA). The median, radial, and axial diffusivities were also projected onto the mean FA skeleton. RESULTS: There were no significant differences in cortical thickness, deep gray matter structures volumes or diffusivity parameters between scans at the two time points (considering P < 0.05). CONCLUSION: No longitudinal differences in cortical thickness, deep gray matter volumes, or white matter integrity were observed in an HIV-positive population on stable HAART, with undetectable viral load and high CD4+ T lymphocytes count.

PURPOSE: To evaluate whether human immunodeficiency virus (HIV)-positive patients with and without executive functions deficits and healthy control subjects differ on cortical thickness and subcortical brain structures volume in vivo. METHODS: In total, 34 HIV-positive patients with executive functions deficits were compared with 13 HIV-positive patients without executive functions deficits and 19 gender-, age-, and education-matched control subjects. Executive functions impairments were classified by performance on the Wisconsin card sorting test. T1 3-dimensional magnetization prepared rapid gradient echo-weighted imaging was performed using a 1.5 Tesla (magnetic resonance) MR scanner. FreeSurfer software was used to perform cortical reconstruction and volumetric segmentation of subcortical gray matter structures. RESULTS: HIV-positive patients with executive functions deficits had smaller volumes in the right and left caudate compared with the HIV-positive patients without executive functions deficits and control groups. In addition, HIV-positive patients with executive functions deficits had smaller volumes in their left accumbens, right putamen, and globus pallidum compared with the control group. No significant differences in cortical thickness were observed between the groups. CONCLUSION: HIV-positive patients with executive functions deficits have reduced volumes of several subcortical structures, primarily in the caudate nucleus.

INTRODUCTION: The success of pharyngeal surgery in the treatment of obstructive sleep apnea syndrome depends on the appropriate selection of patients. OBJECTIVE: To propose a new staging for indication of pharyngeal surgery in obstructive sleep apnea syndrome. METHODS: A total of 54 patients undergoing extended tonsillectomy were retrospectively included, divided into six stages. Stage I: patients with palatine tonsils grade 3/4 and modified Mallampati index 1/2; stage II: palatine tonsils 3/4 and modified Mallampati index 3/4; stage III: palatine tonsils 1/2 and modified Mallampati index 1/2; stage IV: palatine tonsils 1/2 and modified Mallampati index 3/4; stage V: body mass index ≥40 kg/m(2) with palatine tonsils 3/4 and modified Mallampati index 1, 2, 3, or 4. Stage VI: body mass index ≥40 with palatine tonsils 1/2 and modified Mallampati index 1, 2, 3, or 4. RESULTS: The surgical success rates were 88.9%, 75.0%, 35.7%, 38.5%, and 100.0% in stages I-V. CONCLUSION: The presence of hypertrophic palatine tonsils was the anatomical factor in common in the most successful stages (I, II, and V), regardless of body mass index. Although the modified Mallampati index classes 3 and 4 reduced the success rate of surgery in patients with hypertrophic tonsils (stage II), the presence of modified Mallampati index classes 1 and 2 did not favor surgical success in patients with normal tonsils (stage III).

Introdução: O sucesso da cirurgia faríngea no tratamento da síndrome da apneia obstrutiva do sono (SAOS) depende da adequada seleção de pacientes. Objetivo: Propor um novo estadiamento para indicação de cirurgia faríngea na SAOS. Método: Estudo retrospectivo, onde foram inclusos, 54 pacientes submetidos a amigdalectomia ampliada, divididos em 6 estádios. Estádio I: pacientes com tonsilas palatinas graus 3/4 e índice de Mallampati modificado (IMM) 1/2; Estádio II: tonsilas palatinas 3/4 e IMM 3/4; Estádio III: tonsilas palatinas 1/2 e IMM 1/2; Estádio IV: tonsilas palatinas 1/2 e IMM 3/4; Estádio V: IMC (índice de massa corpórea) ≥ com tonsilas palatinas 3/4 e IMM 1, 2, 3 ou 4. Estádio VI: IMC ≥ kg/m2 com tonsilas palatinas 1 ou 2 e IMM 1, 2, 3, ou 4. Resultados: As taxas de sucesso cirúrgico foram de 88,9%; 75,0%; 35,7%; 38,5% e 100,0% nos estádios I a V. Conclusão: A presença de tonsilas palatinas hipertróficas foi o fator anatômico em comum nos estádios de maior sucesso (I, II e V), independente do IMC. Apesar do IMM classe III e IV diminuir a taxa de sucesso da cirurgia em pacientes com tonsilas hipertróficas (estádio II), a presença de IMM classe I e II não favoreceu o sucesso cirúrgico em pacientes com tonsilas normotróficas (estádio III). .

Kaposi's sarcoma is a malignant neoplasm of vascular origin. It occurs mainly among immune deficient individuals, thus it is the most common neoplasm among HIV- positive patients. Its pathogenesis is complex and has not been fully clarified. This case arouses particular interest due to its anatomic location in the retromolar region of a 39-year-old male HIV- positive patient, who presented low white blood cell count and was not undergoing antiretroviral therapy. The emergence of this lesion may be associated with highly active antiretroviral therapy (HAART) discontinuation and leukopenia. Hence, the reestablishment of therapy allows a suitable therapeutic approach and contributes to prognosis and survival rates.
Sarcoma de Kaposi é uma neoplasia maligna de origem vascular que ocorre principalmente em indivíduos com deficiência imunológica, sendo a neoplasia mais comum em pacientes HIV positivos. Sua patogênese é complexa e não está bem estabelecida. Este caso é de interesse pela localização anatômica em região retromolar de paciente soropositivo, que apresentou baixa contagem de células brancas do sangue e que não realizava terapia antirretroviral. O surgimento da lesão pode estar associado à interrupção da terapia antirretroviral altamente ativa (HAART) e à baixa contagem leucocitária. Assim, o restabelecimento da terapia pode permitir a abordagem terapêutica e contribuir para o prognóstico e a sobrevida.
RESUMO
Diffusion-weighted magnetic resonance imaging (DWI) provides image contrasts that are different from conventional magnetic resonance techniques. DWI is particularly sensitive for detecting acute ischemic stroke, but it also has many other clinical applications, including the evaluation of central nervous system (CNS) infections. This article addresses the role of DWI in the differential diagnosis of CNS infections, and discusses the most common DWI findings for each type of infection.

Renal cell carcinoma accounts for 85% of all solid renal tumors in adults. Nearly one quarter of patients has distant metastasis at presentation while another 50% develop metastasis during follow-up. A small percentage of these are solitary metastasis. We report here a case of solitary bone sternal metastasis as an initial presentation of clear-cell renal cell carcinoma in a 56-year-old woman. The prognosis for patients with metastasized renal cell carcinoma is poor; treatment of metastasis is usually palliative and designed to provide comfort and pain relief. Palliative nephrectomy may be considered for control of symptoms. Radical nephrectomy associated with metastatic bone tumor resection is being tested to improve functional status and survival, especially when metastasis involves supporting bones.
RESUMO
INTRODUCTION: Pulmonary amyloidosis is an uncommon disease, characterized by extracellular deposition of fibrillary protein in the lungs. It appears in three forms: tracheobronchial, nodular pulmonary, and alveolar septal. There are few reports of long-term observation of primary pulmonary amyloidosis. CASE PRESENTATION: We present the case of a 47-year-old man who presented with fever, dyspnea, cough and hemoptysis. Chest radiograph and computed tomography revealed multiple pulmonary nodules and masses. The patient underwent open lung biopsy, which diagnosed pulmonary amyloidosis. CONCLUSION: Pulmonary nodular amyloidosis should be considered in the differential diagnosis of pulmonary nodules or masses.
RESUMO
Neurofibromatosis type 2 is an inherited autosomal dominant syndrome, characterized by multiple neoplasms of the central and peripheral nervous system associated with ocular abnormalities. The most common tumor associated with the disease is the vestibulocochlear schwannoma (VIII cranial nerve), and as many as 10% of patients with this tumor have neurofibromatosis type 2. In this report we aim to present a 34-year-old male who was seen for bilateral hearing loss. During his workup, which included cranial computer tomography, he was found to have multiple intracranial masses. Cranial and whole spine magnetic resonance imaging showed bilateral vestibulocochlear schwannoma, multiple meningiomas, and one intramedullary tumor. Based on clinical and imaging findings the diagnostic of neurofibromatosis type 2 was made.
RESUMO
Approximately 90% to 95% of Kaposi sarcoma cases occur in human immunodeficiency virus - infected homosexual and bisexual men. Pulmonary Kaposi sarcoma is uncommon in women, and rarely considered as a potential cause of diffuse lung disease in women with acquired immunodeficiency syndrome. The disease is usually mistaken clinically for pulmonary infection. A 32-year-old woman was admitted with a 2-month history of dyspnea, evening fever, hemoptysis, weight loss, and generalized adenomegaly. Physical examination showed erythematous macules in the lower limbs. Skin and open lung biopsy demonstrated Kaposi sarcoma. Computerized tomography demonstrated peribronchovascular interstitial thickening. Although uncommon, pulmonary Kaposi sarcoma should be considered in the differential diagnosis of diffuse lung disease in women with AIDS.
RESUMO
Telangiectatic adenoma is a new classification of a hepatic lesion. It was previously named telangiectatic focal nodular hyperplasia but it is in fact true adenoma with telangiectatic features. We report here a case of telangiectatic adenoma in a 72-year-old woman. The image features are lack of a central scar, a heterogeneous lesion, hyperintensity in T1-weighted MR images, strong hyperintensity in T2-weighted MR images, and persistent contrast enhancement in delayed-phase contrast-enhanced CT or T1-weighted MR images. It is a monoclonal lesion with potential of malignancy. The treatment of telangiectatic adenoma is surgery, the same way as hepatic adenoma. Focal nodular hyperplasia may be managed by clinical follow-up alone.
RESUMO
OBJETIVO: estudar o uso de medicamentos por gestantes atendidas durante o pré-natal em unidades básicas do Sistema Único de Saúde (SUS) na cidade de Natal, rio Grande do Norte, Brasil. MÉTODOS: foram entrevistadas 610 grávidas, entre o primeiro e o terceiro trimestre de gestação, que compareceram para consulta pré-natal em unidades de saúde localizadas nos quatro distritos sanitários de Natal, entre maio e julho de 2006. Os dados foram coletados com entrevistas estruturadas, baseando-se em perguntas uso-orientadas e medicamento-orientadas. Os fármacos foram classificados de acordo com o Anatomical Therapeutic Chemical Classification System (ATC) e segundo critérios de risco para a gestação da Food and Drug Administration (FDA). Utilizou-se teste do chi2 para análise dos dados. RESULTADOS: eram utilizados 1.505 medicamentos, obtendo-se uma média de 2,4 drogas por mulher. O uso de pelo menos um fármaco na gravidez foi relatado por 86,6 por cento das gestantes. As classes mais utilizadas foram os antianêmicos (35,6 por cento dos medicamentos), analgésicos (24,9 por cento), drogas para distúrbios gastrintestinais (9,1 por cento) e vitaminas (7 por cento). De acordo com a classificação do FDA, dos medicamentos empregados 42,7 por cento pertencem a categoria A de risco; 27,1 por cento à categoria B, 29,3 por cento à categoria C; 0,3 à categoria D e nenhum à categoria X. Foram usados, no primeiro trimestre da gestação, 43,6 por cento dos fármacos. Observou-se maior uso de medicamentos quanto maior a escolaridade e a renda familiar da mulher. A automedicação ocorreu em 12,2 por cento dos medicamentos; esse índice foi maior no primeiro trimestre de gravidez e em gestantes de baixa escolaridade e multigestas. CONCLUSÕES: as gestantes de Natal estão sendo expostas a uma variedade de medicamentos, cuja segurança na gravidez ainda é incerta, o que exige prescrição criteriosa para evitar possíveis danos ao feto.
PURPOSE: to study the use of medicines by pregnant women during prenatal care in clinics of the national public health system in the city of Natal, Brazil. METHODS: a total of 610 pregnant women between the first and the third trimesters of pregnancy were interviewed in the public clinics of the four sanitary districts of Natal, from May to July 2006. The data were collected by a structured questionnaire, based in use-oriented and medicine-oriented questions. The drugs were classified according to the Anatomical Therapeutic Chemical Classification System (ATC), in agreement with the gestation risk criteria from the Food and Drugs Administration (FDA). The statistical analysis was made by the chi2 test. RESULTS: a total of 1,505 drugs were used, with an average of 2.4 medications per woman. The use of at least one drug was found in 86.6 percent of the women. The most frequently used drugs were anti-anemics (35.6 percent), analgesics (24.9 percent), drugs for gastrointestinal disorders (9.1 percent) and vitamins (7 percent). According to the FDA classification, 42.7 percent belonged to category A risk, 27.1 percent to category B, 29.3 percent to category C, 0.3 percent to category D and none to category X. The use of medicines during the first trimester of pregnancy amounted to 43.6 percent. The rate of drug use increased with higher schooling level and family income. Self-medication was found in 12.2 percent of the drug intake and this rate was higher in the first trimester of gestation and with women with low education level and previous gestations. CONCLUSIONS: pregnant women from Natal are being exposed to a variety of medicines with uncertain safety in pregnancy. Therefore, more careful prescription is needed, to avoid possible fetal damage.
