Pulmonary Lymphangioleiomyomatosis on a Post-Menopausal Woman with Chronic Lymphocytic Leukaemia  [PDF]
Bernardo Cunha, Diogo Morgado Concei??o, Carolina Cabo, Nélson Jesus, Lèlita Santos, Armando de Carvalho
Case Reports in Clinical Medicine (CRCM) , 2016, DOI: 10.4236/crcm.2016.53018
Abstract: A 62 years old, post-menopausal female was admitted to the Internal Medicine Ward due to dyspnoea, cough and sputum of at least 2 months. Shortness of breath, cough and hypoxaemia persisted and the patient was submitted to a pulmonary angiogram ct which revealed numerous thin-walled air cysts affecting upper and medial zones of both lungs, typical images of pulmonary lymphangioleiomyomatosis. After discharge to Internal Medicine Consultation Service with Metilprednisolone, the patient was no longer hypoxaemic and remained asymptomatic, even after withdrawal of oral corticosteroid to inhalatory formulation. Further surveillance in short time was scheduled in order to implement rapid imunossupressive treatment when necessary.

Abstract: background and objectives: outpatient surgeries are becoming more frequent. ilioinguinal and iliohypogastric nerve block has been used in postoperative analgesia of patients undergoing outpatient inguinal herniorrhaphy. ultrasound-guided regional anesthesia increases the accuracy of deposition of the local anesthetic around the nerves. the objective of this report was to present a case of ultrasound-guided ilioinguinal and iliohypogastric nerve block for outpatient inguinal herniorrhaphy. case report: a 36-year old male patient, 74 kg, physical status asa i, was scheduled for inguinal herniorrhaphy. ultrasound-guided iliohypogastric and ilioinguinal nerve block was accomplished with 0.5% ropivacaine, followed by total intravenous anesthesia. the patient was discharged from the hospital 4 hours after the procedure with a pain score of 3 in the verbal analogue scale. conclusion: ultrasound-guided iliohypogastric and ilioinguinal nerve block in patients undergoing outpatient inguinal herniorrhaphy can be done as an aid to postoperative analgesia.
A 63-year-old woman presenting with a synovial sarcoma of the hand: a case report
Casal Diogo,Ribeiro Ana,Mafra Manuela,Azeda Concei??o
Journal of Medical Case Reports , 2012, DOI: 10.1186/1752-1947-6-385
Abstract: Introduction Synovial sarcoma is a high-grade, soft-tissue sarcoma that most frequently is located in the vicinity of joints, tendons or bursae, although it can also be found in extra-articular locations. Most patients with synovial sarcoma of the hand are young and have a poor prognosis, as these tumors are locally aggressive and are associated with a relatively high metastasis rate. According to the literature, local recurrence and/or metastatic disease is found in nearly 80% of patients. Current therapy comprises surgery, systemic and limb perfusion chemotherapy, and radiotherapy. However, the 5-year survival rate is estimated to be only around 27% to 55%. Moreover, most authors agree that synovial sarcoma is one of the most commonly misdiagnosed malignancies of soft tissues because of their slow growing pattern, benign radiographic appearance, ability to change size, and the fact that they may elicit pain similar to that caused by common trauma. Case presentation We describe an unusual case of a large synovial sarcoma of the hand in a 63-year-old Caucasian woman followed for 12 years by a multidisciplinary team. In addition, a literature review of the most pertinent aspects of the epidemiology, diagnosis, treatment and prognosis of these patients is presented. Conclusion Awareness of this rare tumor by anyone dealing with hand pathology can hasten diagnosis, and this, in turn, can potentially increase survival. Therefore, a high index of suspicion for this disease should be kept in mind, particularly when evaluating young people, as they are the most commonly affected group.
Sensitivity to primary composition and hadronic models from average shape of high energy cosmic ray shower profiles
Sofia Andringa,Ruben Concei??o,Francisco Diogo,Mário Pimenta
Physics , 2012,
Abstract: The concept of Universal Shower Profile is used to characterize the average behavior of high energy cosmic rays. The shape variables contain important information about composition. They are independent of the primary cross-section by construction, but affected by other hadronic parameters, like multiplicity. The two variables give access to the average nuclear mass of the sample and their compatibility serves as a test of hadronic models.
On exact time-averages of a massive Poisson particle
Welles A. M. Morgado,Silvio M. Duarte Queiros,Diogo O. Soares-Pinto
Statistics , 2011, DOI: 10.1088/1742-5468/2011/06/P06010
Abstract: In this work we study, under the Stratonovich definition, the problem of the damped oscillatory massive particle subject to a heterogeneous Poisson noise characterised by a rate of events, \lambda (t), and a magnitude, \Phi, following an exponential distribution. We tackle the problem by performing exact time-averages over the noise in a similar way to previous works analysing the problem of the Brownian particle. From this procedure we obtain the long-term equilibrium distributions of position and velocity as well as analytical asymptotic expressions for the injection and dissipation of energy terms. Considerations on the emergence of stochastic resonance in this type of system are also set forth.

Diogo, Hilda Concei??o;Melhem, Márcia;Sarpieri, Aldo;Pires, Mario Cezar;
Anais Brasileiros de Dermatologia , 2010, DOI: 10.1590/S0365-05962010000300005
Abstract: background: superficial and subcutaneous mycoses have a high prevalence and, often, chronic evolution. therefore, they need extensive treatment with topic and/or systemic antifungal agents. azoles and alilamines (terbinafine) are first-choice drugs to treat human and animal infections. thus, evaluation of the efficacy of these drugs is important for a successful treatment. however, there are few studies that evaluate the in vitro activity of antifungal agents. objective: to evaluate the in vitro efficacy of terbinafine activity against filamentous fungi and yeasts that cause mycoses. method: the in vitro activity of terbinafine (0.125-100μg) against 10 fungi species was evaluated by the diskdiffusion and microdilution/reference methods to determine the minimum inhibitory concentration (mic). results: we found a high susceptibility to terbinafine in: t. rubrum, m. gypseum, t. mentagrophytes, t. tonsurans, m. canis, c. carrionii and e. floccosum (halo ≥ 40mm with 0.125μg disk). s. hyalinum and c. parapsilosis were considered susceptible, but less than the others. fusarium spp. showed the lowest susceptibility (halo=12mm with 2μg disk; mic 8μg/ml). conclusions: the results of this research confirm previous findings about the efficacy of terbinafine. the drug was shown to be highly effective to treat dermatophyte infections. the disk-diffusion method was easy to use and is a suitable technique for routine use in clinical laboratories.

Abstract: concei??o db, helayel pe, oliveira filho gr - a comparative study between ultrasound- and neurostimulation-guided axillary brachial plexus block. background and objectives: the use of ultrasound in regional blocks is increasingly more frequent. however, very few studies comparing ultrasound and neurostimulation have been conducted. the objective of this study was to compare neurostimulation-guided axillary brachial plexus block with double injection and ultrasound-guided axillary plexus block for hand surgeries. the time to perform the technique, success rate, and complications were compared. methods: after approval by the ethics on research committee of the hospital governador celso ramos, 40 patients scheduled for elective hand surgeries under axillary plexus block were selected. patients were randomly divided into two groups with 20 patients each: neurostimulation (ne) and ultrasound (us) groups. the time to perform the technique, success rate, and complication rate were compared. results: complete blockade, partial failure, and total failure rates did not show statistically significant differences between the us and ne groups. the mean time to perform the technique in the us group (354 seconds) was not statistically different than that of the ne group (381 seconds). patients in the ne group had a higher incidence of vascular punctures (40%) when compared with those in the us group (10%, p < 0.05). the rate of paresthesia during the blockade was similar in both groups (15%). conclusions: the success rate and time to perform the blockade were similar in ultrasound- and neurostimulation-guided axillary plexus block for hand surgeries. the rate of vascular puncture was higher in neurostimulation-guided axillary plexus block.
Bloqueios nervosos guiados por ultra-som
Helayel, Pablo Escovedo;Concei??o, Diogo Brüggemann da;Oliveira Filho, Getúlio Rodrigues de;
Revista Brasileira de Anestesiologia , 2007, DOI: 10.1590/S0034-70942007000100012
Abstract: background and objectives: ultrasound-guided nerve blocks are based on the direct visualization of nerve structures, needle, and adjacent anatomic structures. thus, it is possible to place the local anesthetic precisely around the nerves and follow its dispersion in real time, obtaining, therefore, more effective blockades, reduced dependency on anatomic references, decreased anesthetic volume, and increased safety. contents: the aim of this paper was to review the physical mechanisms of image formation, ultrasound anatomy of the neuro axis and of the brachial and lumbosacral plexuses, equipment and materials used in the blockades, settings of the ultrasound equipment to improve the image, planes of visualization of the needles, the techniques, and training in ultrasound-guided nerve blocks. conclusions: the steps for a successful regional block include the identification of the exact position of the nerves, the precise localization of the needle, without causing injuries to adjacent structures, and, finally, the careful administration of the local anesthetic close to the nerves. although neurostimulation is very useful in identifying nerves, it does not fulfill all those requirements. therefore, it is believed that ultrasound-guided nerve blocks will be the technique of choice in regional anesthesia in a not too distant future.
