Results of prostate cancer screening in non-symptomatic men

Objectives: To verify prostate cancer prevalence in non-symptomatic men between 50 and 70 years old as well as cancer characteristics. Material and Methods: 2815 non-symptomatic men had total PSA and digital rectal examination performed between March 1998 and April 1998. Racial distribution was: 2331 Caucasians (83.9%), 373 Blacks (13.4%) and 75 Asiatic (2.7%). PSA was normal in 2554 (91.4%), 4 to 10 in 177 (6.3%) and greater than 10 in 64 (2.3%). DRE was normal in 2419 (86.3%), suspicious in 347 (12.4%) and characteristic for cancer in 37 (1.3%). Men with abnormal DRE and/or PSA had transrectal prostate biopsy indicated. Results: 461 biopsies were done and 78 tumors was detected (prevalence = 2.8%). Prevalence was progressively higher with age (p < 0.001), PSA level (p < 0.0001) and DRE findings (p = 0.0216). Cancer prevalence in Blacks was 1.65 times higher than in Caucasians (p > 0.05) and 94.9% of detected tumors were moderately or poorly differentiated. Sensibility, specificity, positive predictive value, negative predictive value and total accuracy for PSA were respectively: 66.6%; 89.7%; 51.7%; 94.2% and 86.5%. For DRE, the respective values were: 49.1%; 79.4%; 50.9%; 78.3% and 70.3%. Conclusions: prostate cancer prevalence in the studied population (2.8%) was similar to that of other countries populations. Cancer prevalence in blacks was 1.65 times higher than in Caucasians (difference was not statistically significant). Cancer prevalence becomes higher with aging. The association of DRE and PSA is of paramount importance for cancer diagnosis. The great majority of detected tumors (94.9%) was moderately and poorly differentiated. Brazil probably needs regional studies to better characterize prostate cancer epidemiology due to population heterogeneity.

Um transtorno delirante somático atípico

This paper describes the case of a 38 year-old single man with a previous history of social phobia and alcoholism, who presented an unusual pathological belief during the last 9 years. He believe that the muscles of his arms were loose, separated from the bones, and that a green fluid flowed from his shoulders, running under the skin towards his fingers, and returning to the shoulders. He also reported pain, weakness and sensations of loose and fluffy muscles, besides having visual and kinesthetic hallucinations and judgement impairment. No other psychopathological manifestations were observed. There was a worsening of the complaints and depressive symptoms with the use of pimozide and no improvement with fluoxetine, venlafaxine or risperidone. He is presently taking sulpiride. Psychopathological issues and difficulties in diagnosis and treatment are discussed.

Surgical treatment of metachronous metastases in different organs following radical nephrectomy

Renal clear cell carcinoma (RCCC) is a neoplasia resistant to radio and chemotherapy, with surgical treatment being the procedure that is recognized for its curative treatment. This case report demonstrates the success of an aggressive surgical treatment for consecutive and late metachronous metastases following radical nephrectomy. Case report: Asymptomatic 50-year old man. During a routine examination, an incidental mass was found by renal ultrasonography. He underwent right radical nephrectomy due to RCCC in June 1992. During the follow-up metastases were evidenced in cerebellum on the seventh year, and in left lung and pancreas on the eighth year following the radical nephrectomy, with all of them successfully treated by surgical excision. Comments: The surgical excision of consecutive and late metachronous metastases in different organs arising from RCCC is feasible, being a good therapeutic alternative in selected cases.

A família do portador de sofrimento psíquico e os serviços de saúde mental: Estudo de caso

This qualitative research, case study type, aimed at presenting the understanding of psychic sufferers in search for mental health services during emergency situation, partial hospitalization or in ambulatory services. 12 family members were interviewed. They reported difficulties in the attendance in the emergency room when the patient is in crisis, as well as doctors considering merely the present symptomatology and undervaluing their own knowledge of the sickening process. The day-care hospital is conceived as a place to provide care, occupation and should teach as a school. The ambulatory service represents for the family the possibility of the patient being responsible for their attendance to the consultations and for the correct use of the medication.

Oral manifestations during chemotherapy for acute lymphoblastic leukemia: A case report

A 14-year-old, male patient was referred for the treatment of mucositis, idiopathic facial asymmetry, and candidiasis. The patient had been undergoing chemotherapy for 5 years for acute lymphoblastic leukemia. He presented with a swollen face, fever, and generalized symptomatology in the mouth with burning. On physical examination, general signs of poor health, paleness, malnutrition, and jaundice were observed. The extraoral clinical examination showed edema on the right side of the face and cutaneous erythema. On intraoral clinical examination, generalized ulcers with extensive necrosis on the hard palate mucosa were observed, extending to the posterior region. Both free and attached gingivae were ulcerated and edematous with exudation and spontaneous bleeding, mainly in the superior and inferior anterior teeth region. The tongue had no papillae and was coated, due to poor oral hygiene. The patient also presented with carious white lesions and enamel hypoplasia, mouth opening limitation, and foul odor. After exfoliative cytology of the affected areas, the diagnosis was mixed infection by Candida albicans and bacteria. Recommended treatment was antibiotics and antifungal administration, periodontal prophylaxis, topical application of fluor 1.23%, and orientation on and control of proper oral hygiene and diet during the remission phase of the disease.

Diphyllobothriasis, Brazil

Cases of human diphyllobothriasis have been reported worldwide. Only 1 case in Brazil was diagnosed by our institution from January 1998 to December 2003. By comparison, 18 cases were diagnosed from March 2004 to January 2005. All patients who became infected ate raw fish in sushi or sashimi.

Síndrome do climatério

The climateric is characterized by progressive hipoestrogenism and by tissue and functional alterations that leads the women to aging. The diagnosis approach needs to consider the symptoms originated by estrogenic deficiency and by the more prevalent chronic diseases in this lifetime, for instance, among others, the cardiovascular and osteoporosis diseases, witch need a systematic screening. The therapeutic management must consider the proposition of healthy life habits and, when indicated, pharmacological treatment for estrogenic deficiency or for anothers comorbidities existent. The estroprogestative hormonal therapeutic is a valuable tool to provide health and better quality of life, once obeyed the individualized criterion of the cases, doses, hormonal composition and mainly of the opportunity of intervention. There are nonhormonal alternatives to treat the menopausal symptoms, as the antidepressives and phytoestrogens. It's also advised to combine with regular physical activities and adequate calcium intake. © Copyright Moreira Jr. Editora. Todos os direitos reservados.

Depression severity levels and cognitive functions in institutionalized elderly patients

Depression is a highly prevalent illness among institutionalized aged and assumes peculiar characteristics such as the risk for progressing to dementia. The aims of this study was to assess the cognitive functions of institutionalized elderly with clinical diagnosis of depression and compare the severity of depressive symptoms with cognitive performance. From 120 residents at a nursing home in Rio Claro, Brazil, we study 23 individuals (mean age: 74.3 years; mean schooling: 4.0 years) with diagnosis of depression. At first, a clinical diagnosis of depression and measurement of its symptoms using the Geriatric Depression Scale were performed. The patient then underwent a neuropsychological assessment based on the following tests: Mini-Mental Examination, Verbal Fluency, Visual Perception, Immediate Memory, Recent Memory, Recognition, Clock Drawing Test. The patients were divided into two groups: those with less severe depression symptoms (Group 1: N=9) and more severe symptoms (Group 2: N=14). The significant difference between symptom severity of the two groups was p=0.0001. Patients with more severe symptoms revealed a slightly inferior cognitive performance in most of the tests when compared to those with less severe symptoms (p>0.05). In relation to Verbal Fluency, patients with more severe depression symptoms presented a significantly inferior cognitive performance when compared to those with less severe symptoms (p=0.0082). Verbal Fluency revealed to be a more sensitive test for measuring early cognitive alterations in institutionalized aged with depression, and appears to be a useful resource in monitoring the cognitive functions of patients faced with the risk of dementia. © Copyright Moreira Jr. Editora.

Sporotrichosis in an HIV-positive man with oral lesions: A case report

Background: Sporotrichosis is a granulomatous fungal infection caused by Sporothrix schenckii, which frequently causes cutaneous or lymphocutaneous lesions and rarely has oral manifestations. Case: A 38-year-old, white, HIV-positive man complained of a 5.0-cm, symptomatic, ulcerated lesion with thin, superficial granulation in the soft palate extending to the uvula. Exfoliative cytology of this oral lesion showed chronic granulomatous inflammatory alterations and extracellular fungal structures consisting of periodic acid-Schiff-positive budding cells and spherical or elongated (cigar bodies) free spore forms. Conclusion: The clinical and cytologic findings allowed the diagnosis of sporotrichosis, demonstrating the importance of cytodiagnosis in fungal diseases. © The International Academy of Cytology.

Early onset obsessive-compulsive disorder with and without tics

Introduction: Research suggests that obsessive-compulsive disorder (OCD) is not a unitary entity, but rather a highly heterogeneous condition, with complex and variable clinical manifestations. Objective: The aims of this study were to compare clinical and demographic characteristics of OCD patients with early and late age of onset of obsessive-compulsive symptoms (OCS); and to compare the same features in early onset OCD with and without tics. The independent impact of age at onset and presence of tics on comorbidity patterns was investigated. Methods: Three hundred and thirty consecutive outpatients meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for OCD were evaluated: 160 patients belonged to the early onset group (EOG): before 11 years of age, 75 patients had an intermediate onset (IOG), and 95 patients were from the late onset group (LOG): after 18 years of age. From the 160 EOG, 60 had comorbidity with tic disorders. The diagnostic instruments used were: the Yale-Brown Obsessive Compulsive Scale and the Dimensional Yale-Brown Obsessive Compulsive Scale (DY-BOCS), Yale Global Tics Severity Scale; and Structured Clinical Interview for DSM-IV Axis I Disorders-patient edition. Statistical tests used were: Mann-Whitney, full Bayesian significance test, and logistic regression. © MBL Communications Inc.

Significância clínica de tromboembolismo venoso recorrente

Recurrent venous thromboembolism is a significant problem leading to increased morbidity and mortality. It has a high impact on patients' quality of life and imposes a great financial burden on society. Cumulative recurrence has been reported as 40% at 10 years, while the chance of developing postthrombotic signs and symptoms in the lower extremities almost quadruples when ipsilateral. There is also a higher chance of developing pulmonary hypertension. Important factors for recurrence are unprovoked episodes of deep vein thrombosis, malignancy and older age. The evidence for other factors is controversial. Accurate diagnosis and treatment tailored to the patients' history, thrombotic events and risk factors are necessary to optimize management and prevent recurrence.

Deficiências de macronutrientes em plantas de soja cv. BRSMG 68 (Vencedora) cultivada em solução nutritive

Soybean is a crop of great importance for Brazil, and knowledge of their nutritional status allows production and high quality products. Thus, the present work aimed to evaluate the culture of the soybean cv. BRSMG 68 (Vencedora), submitted to macronutrients omission on the development, nutritional status and the visual symptomatology of nutrient deficiency. The design used was completely randomized, with seven treatments that corresponded to the complete (macro and micronutrients) solution and the individual omission of N, P, K, Ca, Mg and S. The treatments were applied two weeks after the emergency of the soybean. The nutrient solution was constantly oxygenated and replaced weekly, and the pH monitored daily remained around 5. After six weeks of application of the treatments, the height of the plants, number of leaves, stem diameter was evaluated, matter dry accumulated in the roots, it leaves aerial and the nutritional state and the characterization of the visual symptoms. The macronutrient deficiency promoted a decrease in production of root and shoot dry mass of soybean cultivar BRSMG 68 (Vencedora) in nutrient solution, for the full treatment. The most limiting nutrient for dry matter production of soybean compared to complete treatment were N, S and K, with decreases of 90, 76 and 73%, respectively. Individual omissions resulted in morphological changes, which were translated by characteristic visual symptoms of nutritional deficiency of the respective nutrient.

Adverse drug reaction as cause of hospital admission of elderly people: a pilot study

The objective of this study was to estimate the prevalence of adverse drug reactions (ADR) related to hospital admission of elderly people, identifying the use of potentially inappropriate medication (PIM), the ADR and the risk factors associated with the hospitalization. A cross-sectional study was conducted in a private hospital of São Paulo State, Brazil. All patients aged ≥ 60 years, admitted in the general practice ward in May 2006 were interviewed about the drugs used and the symptoms/complaints that resulted in hospitalization. More than a half (54.5 %) of elderly hospitalizations were related with ADR. The therapeutic classes involved with ADR were: cardiovascular (37.7 %), central nervous (34.6 %) and respiratory (5.7 %). The ADR observed were disorders in circulatory (28.4 %), digestive (20.0 %) and respiratory (18.9 %) tracts. 27 elderly had made PIM and in 20 of them this was the cause of hospitalization. Polypharmacy was an ADR risk factor (p = 0.021).These data allows the healthcare professionals upgrade, qualifying them in pharmcovigilance.

Dimensional correlates of poor insight in obsessive-compulsive disorder

Background: Cross-sectional studies have associated poor insight in patients with obsessive-compulsive disorder (OCD) with increased OCD symptom severity, earlier age of onset, comorbid depression, and treatment response. The goal of this current study was to examine the relationship between dimensions of OCD symptomatology and insight in a large clinical cohort of Brazilian patients with OCD. We hypothesized that poor insight would be associated with total symptom severity as well as with hoarding symptoms severity, specifically. Methods: 824 outpatients underwent a detailed clinical assessment for OCD, including the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), the Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS), the Brown Assessment of Beliefs Scale (BABS), a socio-demographic questionnaire, and the Structured Clinical Interview for axis I DSM-IV disorders (SCID-P). Tobit regression models were used to examine the association between level of insight and clinical variables of interest. Results: Increased severity of current and worst-ever hoarding symptoms and higher rate of unemployment were associated with poor insight in OCD after controlling for current OCD severity, age and gender. Poor insight was also correlated with increased severity of current OCD symptoms. Conclusion: Hoarding and overall OCD severity were significantly but weakly associated with level of insight in OCD patients. Further studies should examine insight as a moderator and mediator of treatment response in OCD in both behavioral therapy and pharmacological trials. Behavioral techniques aimed at enhancing insight may be potentially beneficial in OCD, especially among patients with hoarding. © 2011.

Bovine herpesvirus-5 infection in a rabbit experimental model: Immunohistochemical study of the cellular response in the CNS

Since little information is available regarding cellular antigen mapping and the involvement of non-neuronal cells in the pathogenesis of bovine herpesvirus type 5 (BHV-5) infection, it were determined the BHV-5 distribution, the astrocytic reactivity, the involvement of lymphocytes and the presence of matrix metalloproteinase (MMP)-9 in the brain of rabbits experimentally infected with BHV-5. Twelve New Zealand rabbits that were seronegative for BHV-5 were used for virus inoculation, and five rabbits were used as mock-infected controls. The rabbits were kept in separate areas and were inoculated intranasally with 500 μl of virus suspension (EVI 88 Brazilian isolate) into each nostril (virus titer, 107.5 TCID50). Control rabbits were inoculated with the same volume of minimum essential medium. Five days before virus inoculation, the rabbits were submitted to daily administration of dexamethasone. After virus inoculation, the rabbits were monitored clinically on a daily basis. Seven rabbits showed respiratory symptoms and four animals exhibited neurological symptoms. Tissue sections were collected for histological examination and immunohistochemistry to examine BHV-5 antigens, astrocytes, T and B lymphocytes and MMP-9. By means of immunohistochemical and PCR methods, BHV-5 was detected in the entire brain of the animals which presented with neurological symptoms, especially in the trigeminal ganglion and cerebral cortices. Furthermore, BHV-5 antigens were detected in neurons and/or other non-neural cells. In addition to the neurons, most infiltrating CD3 T lymphocytes observed in these areas were positive for MMP-9 and also for BHV-5 antigen. These infected cells might contribute to the spread of the virus to the rabbit brain along the trigeminal ganglia and olfactory nerve pathways. © 2013 Elsevier Ltd.
