Improved Endothelial Function and Reversal of Myocardial Perfusion Defects after Aerobic Physical Training in a Patient with Microvascular Myocardial Ischemia

The objective of this report is to document the effects of an aerobic training program on myocardial perfusion, and endothelial function abnormalities, and on the relief of angina in a patient with microvascular myocardial ischemia. A 53-year-old female patient exhibited precordial pain on effort and angiographically normal coronaries. Her symptoms had been present for 4 yrs despite pharmacologic treatment for the control of risk factors, with myocardial perfusion scintigraphy revealing an extensive reversible perfusion defect. She was submitted to aerobic training for 4 mos, obtaining significant improvement of the anginal symptoms. Additionally, after the aerobic training program, scintigraphy revealed the disappearance of the myocardial perfusion defect, with a marked improvement of endothelium-dependent vasodilatory response and an improved quality-of-life score. These results suggest that aerobic training can improve endothelial function, leading to a reduction of ischemia and an improved quality-of-life in patients with microvascular myocardial ischemia.

Heterogeneity in the molecular basis of ACTH resistance syndrome

Objective: ACTH resistance syndromes are rare, autosomal, and genetically heterogeneous diseases that include familial glucocorticoid deficiency (FGD) and triple A syndrome. FGD has been shown to segregate with mutations in the gene coding for ACTH receptor (MC2R) or melanocortin 2 receptor accessory protein (MRAP), whereas mutations in the triple A syndrome (AAAS, Allgrove syndrome) gene have been found in segregation with triple A syndrome. We describe the clinical findings and molecular analysis of MC2R, MRAR and AAAS genes in five Brazilian patients with ACTH resistance syndrome. Design and methods: Genomic DNA from patients and their unaffected relatives was extracted from peripheral blood leucocytes and amplified by PCR, followed by automated sequencing. Functional analysis was carried out using Y6 cells expressing wild-type and mutant MC2R. Results: All five patients showed low cortisol and elevated plasma ACTH levels. One patient had achalasia and alacrima, besides the symptoms of adrenal insufficiency. The molecular analysis of FGD patients revealed a novel p.Gly116Val mutation in the MC2R gene in one patient and p.Met1Ile mutation in the MRAP gene in another patient. Expression of p.Glyll.6Val MC2R mutant in Y6 cells revealed that this variant failed to stimulate cAMP production. The analysis of the AAAS gene in the patient with triple A syndrome showed a novel g.782_783deITG deletion. The molecular analysis of DNA from other two patients showed no mutation in MC2R, MRAP or AAAS gene. Conclusions: In conclusion, the molecular basis of ACTH resistance syndrome is heterogeneous, segregating with genes coding for proteins involved with ACTH receptor signaling/expression or adrenal gland development and other unknown genes.

Primary adenocarcinoma of the fallopian tube as an incidental finding during surgery in a postmenopausal patient with unspecific pelvic pain

Primary fallopian tube carcinoma (PFTC) is a rare gynecologic neoplasm and is usually diagnosed late and presents classically with a,characteristic group of symptoms. We describe a case of a 76-year-old woman who underwent TVS requested by the family physician due to unspecific pelvic pain. An adnexal mass was found with morphology associated with high levels of CA125 suggestive of a malignant tumor. During laparotomy, a mass located in the left tube was found. Histopathology confirmed PFTC. Total hysterectomy, salpingo-oophorectomy and adjuvant chemotherapy with carboplatin/paclitaxel were performed. The patient has not yet presented any signs of recurrence.

Access to tuberculosis diagnosis in Itaborai City, Rio de Janeiro, Brazil: the patient`s point of view

SETTING: Itaborai Municipality in Rio de Janeiro, Brazil. OBJECTIVE: To evaluate access to tuberculosis (TB) diagnosis for users of the Family Health Program (FHP) and Reference Ambulatory Units (RAUs). DESIGN : A cross-sectional study was conducted in Itaborai City, Rio de Janeiro, Brazil. Between July and October 2007, a sample of 100 TB patients registered consecutively with the TB Control Program was interviewed using the primary care assessment tool. The two highest scores, describing `almost always` and `always`, or `good` and `very good`, were used as a cut-off point to define high quality access to diagnosis. RESULTS: FHP patients were older and had less education than RAU interviewees. Sex and overcrowding did not differ in the two groups. Patient groups did not differ with regard to the number of times care was sought at a unit, transport problems, cost of attending units and availability of consultation within 24 h. Adequate access to diagnosis was identified by 62% of the FHP patients and 53% of the RAU patients (P = 0.01). CONCLUSION: In Itaborai, Rio de Janeiro, TB patients believe that the FHP units provide greater access to TB diagnosis than RAUs. These findings will be used by the Department of Health to improve access to diagnosis in Itaborai.

Effect of+3.00 diopter and+4.00 diopter additions in multifocal intraocular lenses on defocus profiles, patient satisfaction, and contrast sensitivity

PURPOSE: To evaluate the advantages and disadvantages of the new low-addition (add) (+3.00 diopter [D]) ReSTOR multifocal IOL compared with the preceding ReSTOR model with +4.00 D add. SETTING: University Eye Hospital, Tuebingen, Germany. DESIGN: Comparative case series. METHODS: Patients with a +3.00 D or +4.00 D add multifocal IOL were examined for uncorrected and distance-corrected visual acuity at distance, intermediate, and near. A defocus profile was assessed, individual reading distance and the distance for lowest intermediate visual acuity were determined. Patient satisfaction was evaluated with a standardized questionnaire. Contrast sensitivity was tested under mesopic and photopic conditions. RESULTS: Uncorrected and distance-corrected intermediate visual acuities were statistically significantly better in the +3.00 D add group (24 eyes) than in the +4.00 D add group (30 eyes); distance and near visual acuities were not different between groups. The defocus profile significantly varied between groups. The +4.00 D add group had a closer reading distance (33.0 cm) than the +3.00 D add group (43.5 cm), a closer point of lowest intermediate visual acuity (65.8 cm versus 86.9 cm) and worse lowest intermediate visual acuity (20/59 +/- 4.5 letters [SD] versus 20/48 +/- 5.5 letters). Thus, patients in the +3.00 D add group reported being more satisfied with intermediate visual acuity. The +3.00 D add group reported more glare but less halos than the +4.00 D add group; contrast sensitivity was not different. CONCLUSION: The lower addition resulted in a narrower defocus profile, a farther reading distance, and better intermediate visual acuity and thus increased patient satisfaction.

Tetrasomy 8 in a patient with chronic lymphocytic leukemia

We report a case of a 47-year-old man diagnosed with chronic lymphocytic leukemia (CLL) with two extra copies of chromosome 8. Classical cytogenetic analysis by the immunostimulatory combination of DSP30 and interleukin 2 showed tetrasomy of chromosome 8 in 60% of the metaphase cells (48,XY,+8,+8[12]/46,XY[8]). Spectral karyotype analysis confirmed the abnormality previously seen by G banding. Additionally, interphase fluorescence in situ hybridization using an LSI CEP 8 probe performed on peripheral blood cells without any stimulant agent showed tetrasomy of chromosome 8 in 54% of analyzed cells (108 of 200). To our knowledge, tetrasomy 8 as the sole chromosomal abnormality in CLL has not been previously described. The prognostic significance of tetrasomy 8 in CLL remains to be elucidated. However, the patient has been followed up in the outpatient hospital since 2004 without any therapeutic intervention and has so far remained stable. (C) 2010 Elsevier Inc. All rights reserved.

Sexual Dysfunction Treatment in a Patient With Mullerian Agenesy Submitted to Neovaginoplasty: A Case Report

Vagina agenesis is a rare entity. Mayer-Rokitansky-Kuster-Hauser syndrome is the most significant cause of vagina agenesis, whereas the second most common cause is complete androgen syndrome. Surgical treatment can propitiate a vaginal reconstruction, but sexual function depends on several factors that affect sexual performance. Many reports focus on the intraoperative and postoperative results and only describe the global approach to these patients, but reports focusing on the management of these patients to enable them to have a normal sexual life are lacking. This case report highlights a multidisciplinary treatment for this kind of morbidity and emphasizes the necessity of incorporating careful attention to sexual health in the treatment of these patients so that they may achieve a good therapeutic response, resulting in a pleasurable sexual life and a good quality of living.

Bone Marrow Involvement in a Patient with Paracoccidioidomycosis: A Rare Presentation of Juvenile Form

Paracoccidioides brasiliensis rarely shows bone marrow involvement and its response to treatment with itraconazole in children needs further assessment. We describe here a child with a juvenile disseminated form of paracoccidioidomycosis, which showed reticuloendothelial system involvement and the presence of Paracoccidioides brasiliensis in the bone marrow. The patient showed an effective and rapid response to itraconazole therapy.

Septic shock caused by Plesiomonas shigelloides in a patient with sickle beta-zero thalassemia

Invasive infection and extraintestinal complications are rarely caused by Plesiomonas shigelloides, a water-borne bacterium belonging to the Vibrionaceae family. We report a case of a 16-year-old female patient with sickle beta-zero thalassemia who survived septic shock caused by P. shigelloides associated with secondary acute respiratory distress syndrome and disseminated intravascular coagulation. Treatment with a carbapenem was successful, and the patient recovered without any sequelae. The previous reports of P. shigelloides sepsis are cited, and possible pathogenic mechanisms are discussed.

Kaposi sarcoma and paracoccidioidomycosis in the same fragment of oral mucosa biopsy: a rare association in human immunodeficiency virus-positive patient. A case report

The immunossuppression caused by HIV infection makes the affected individuals more susceptible to some diseases including infections, neoplasms, or even the association between them. Kaposi sarcoma (KS) is the most common AIDS-related neoplasm, featured as an angioproliferative disorder. Its cause seems to be related to the human herpesvirus type 8 and it is usually associated with lower CD4+ T cell count. Oral involvement is frequent, presenting red to blue-purplish plaques, maculaes, and nodules. On the other hand, paracoccidioidomycosis (PCM) is a systemic mycosis, endemic in Latin America, caused by Paracoccidioides brasiliensis. This mycosis is not commonly related to human immunodeficiency virus (HIV) infection, although PCM can be present in immunosuppression cases. Oral lesions, as granulomatous ulcers, are often identified in seropositive patients with PCM. A rare case, in which a male HIV-positive patient presented simultaneously Kaposi sarcoma and PCM in the same fragment of oral mucosa biopsy, is described. To the best of our knowledge, this concomitant association had not been previously described. (C) 2011 Elsevier Inc. All rights reserved.
