Síndrome das pernas inquietas: Diagnóstico e tratamento. Opinião de especialistas Brasileiros

This article contains the conclusions of the November 17-18, 2006 meeting of the Brazilian Study Group of Restless Legs Syndrome (GBE-SPI) about diagnosis and management of restless legs syndrome (RLS). RLS is characterized by abnormal sensations mostly but not exclusively in the legs which worsen in the evening and are improved by motion of the affected body part. Its diagnosis is solely based on clinical findings. Therapeutic agents with efficacy supported by Class I studies are dopamine agonists, levodopa and gabapentine. Class II studies support the use of slow release valproic acid, clonazepan and oxycodone. The GBE-SPI recommendations for management of SPI are sleep hygiene, withdrawal of medications capable of worsening the condition, treatment of comorbidities and pharmacological agents. The first choice agents are dopaminergic drugs, second choice are gabapentine or oxycodone, and the third choice are clonazepan or slow release valproic acid.

Unusual wooden foreign body in the palate

We report a case of a palatal calcified foreign body simulating an odontogenic lesion. Surgical exploration revealed a calcified mass that was analysed under light microscopy and identified as a vegetal foreign body. Further scanning electron microscopy analysis revealed that the foreign body was a piece of wood. Hard palate foreign bodies have been reported previously, however, it seems that this is the first case of its kind. © 2007 Nature Publishing Group.

Anovulvar cleft and vaginal prolapse-hyperplasia in a bitch

This report presents the case of a nine-month-old bitch with incomplete occlusion of the skin and mucosa between the anus and dorsal commissure of the vulva. This anomaly, known as anovulvar cleft, was associated with a vaginal prolapse-hyperplasia. Anovulvar cleft is a rare condition in bitches and is caused by incomplete closure of the dorsal urogenital folds. Anovulvar cleft can lead to clitoritis, abrasion, dryness and devitalisation of the smooth exposed mucosa. Surgery can correct the condition. In the present study, surgical resection of the hyperplasic vaginal tissue associated with perineoplasty using an inverted V-shaped incision showed excellent results. An ovariohysterectomy was also performed to prevent recurrence of the vaginal prolapse-hyperplasia. © 2007 British Small Animal Veterinary Association.

Mixed germ cell tumor of the pituitary-hypothalamic region presenting as craniopharyngioma: Case report and review of the literature

Craniopharyngiomas and germ cell tumors (GCT) may affect the pituitary-hypothalamic region during childhood. Although different in origin, their clinical and radiological features may be similar. In this article we present a 5-year-old girl with clinical and radiological findings (computer tomography calcification) that were initially considered as craniopharyngioma. However clinical outcome, blood and cerebral spinal fluid tumoral markers, and results from anatomopathology and immunohistochemistry disclosed a mixed GCT. This case report highlights that some clinical features and radiological findings of pituitary-hypothalamic tumors may be misdiagnosed as craniopharyngioma mainly when there is a mature teratoma with cartilaginous tissue differentiation.

Regional odontodysplasia in early childhood: A clinical and histological study

Regional odontodysplasia (RO) is a rare disorder of dental development. The affected teeth are clinically hypoplastic and hypocalcified, presenting a ghost-like appearance radiographically. The aim of this work was to report a clinical case of a child with both primary and permanent dentition affected by RO. The conducted therapy was based on a conservative approach, which consisted of follow-up clinical evaluations of the anomalous teeth. However, the endodontic treatment of the primary incisors failed. Then, the chosen option for patient rehabilitation became extraction followed by removable of prosthesis confection. The extracted teeth were processed for histological analysis. In spite of the uncertain prognosis, but taking into account the psychological aspects of the patient, a conservative approach in an attempt to maintain those viable teeth in the oral cavity should be established.

Métodos de avaliação da eficácia dos tratamentos para a dor.

Pain is a subjective condition and, thus, difficult to measure. The best tools to assess pain are the pain evaluation questionnaires, which provide either diagnostic, pain evolution or pain intensity information. To provide information which could help differentiate between nociceptive pain and neuropathic pain is one of the most important functions of these questionnaires. The questionnaires can measure pain intensity, quality of life, or sleep quality. Quality of life and sleep are two really important characteristics to assess the pain impact on patients' life. Pain intensity assessing questionnaires combine physical evaluations with questions, providing information either from the patient sensations or clinical assessment of pain manifestations as well as the underlying biological mechanisms (such as hyperalgesia or allodynia). For example, the Pain Detect questionnaire has two parts: the patient form (intuitive, with pictures and easy understandable) and the physician form. Thus, in this questionnaire, subjective information is provided by the patient and the objective one is provided by the physician. Other pain intensity questionnaires are NPSI, DN4, LANSS or StEP. Quality of life questionnaires are versatile (can be used in different pathologies). These questionnaires include functional self-evaluation questions, and other ones associated to physical and mental health. Two of such quality of life questionnaires are SF-36 and NHP. Sleep evaluation questionnaires include quantitative features such as the number of sleep interruptions, sleep latency or sleep duration as well as qualitative characteristics such as rest sensation, mood and dreams. One of the most used sleep evaluation questionnaires is PSQI, which includes patient questions and bed-partner questions, providing information from two points of view.

Desmoplastic small round cell tumor of the kidney mimicking wilms tumor: A case report and review of the literature

Desmoplastic small round cell tumor (DSRCT) is a rare, aggressive, malignant neoplasm usually present with the widespread abdominal serosal involvement and affects mainly adolescents and young adults. When presenting within visceral organs, as kidney, the diagnosis of DSRCT imposes significant difficulties. We present a case of primary DSRCT of the kidney in a 10-year-old boy mimicking clinically and pathologically Wilms tumor. The tumor showed morphologic and immunohistochemical features of DSRCT and the presence of the Ewing sarcoma and Wilm tumor 1 fusion transcripts resulting from the t(11;22) (p13;q12) reciprocal translocation. DSRCT should be considered in the differential diagnosis of Wilm tumor and other small blue-round cell tumors of the kidney. © 2009 by Lippincott Williams & Wilkins.

Myositis ossificans traumatica of the medial pterygoid muscle: a case report.

In this report, we present a case of myositis ossificans traumatica (MOT) of the medial pterygoid muscle that had developed after mandibular block anesthesia administered for endodontic treatment of the lower right second molar, demonstrating typical features of this condition. MOT should be considered as a differential diagnosis when there is severe limitation of jaw opening and an associated trauma. Panoramic radiographs and axial and coronal computed tomography (CT) scans can effectively delineate the calcified mass. Other imaging studies that may be helpful include magnetic resonance imaging (MRI), bone scans, and ultrasound. As shown in our case, calcified masses were found in the right mandibular angle, which severely limited jaw opening. Some earlier reported cases of MOT were treated by extraoral surgical approaches with complete removal of the evolving muscle. The aim of this case report is to present only the diagnostic imaging aspects of myositis ossificans traumatica.

Mucocele of the glands of Blandin-Nuhn-clinical, pathological, and therapeutical aspects

Purpose: This study aims to review anatomical, clinical, and pathological concepts as well as to discuss the most adequate therapeutic approach to the mucoceles of the glands of Blandin-Nuhn. Discussion: The glands of Blandin-Nuhn are localized in the ventral part of the tongue, next to the apex in the lingual median plane. Development of a mucocele in this site is rarely seen; besides, as the glands of Blandin-Nuhn are not encapsulated and are directly overlapped to the muscle tissues, their manipulation tends to be different from the other oral mucoceles. Conclusion: As Blandin-Nuhn mucoceles are uncommon and their clinical appearance could be similar to other lesions, it is important that health professionals know their clinical and histopathological features to avoid having them misdiagnosed. © 2010 Springer-Verlag.

Noninvasive aspergillosis as a maxillary antrolith: report of a rare case.

Maxillary antrolithiasis is characterized by masses of tissue of endogenous or exogenous origin that calcify within the maxillary sinuses. Aspergillosis is a fungal disease in which the maxillary sinus is a primary site of infection. Aspergillosis mycetoma, its noninvasive form, is the most prevalent modality of the disease in the maxillary sinuses. In approximately half of the cases reported in the literature, calcification of the fungal mycelia, which later became antroliths, was verified. This article reports a rare case of the accidental discovery of a maxillary antrolith associated with noninvasive aspergillosis in an immunocompetent and asymptomatic 56-year-old woman. The diagnosis and therapeutic procedures used in treating the patient are discussed as well as the probable iatrogenic origin of the fungal pathology.

Leprosy: a review of laboratory and therapeutic aspects - Part 2

Leprosy is a chronic infectious condition caused by Mycobacterium leprae(M. leprae). It is endemic in many regions of the world and a public health problem in Brazil. Additionally, it presents a wide spectrum of clinical manifestations, which are dependent on the interaction between M. leprae and host, and are related to the degree of immunity to the bacillus. The diagnosis of this disease is a clinical one. However, in some situations laboratory exams are necessary to confirm the diagnosis of leprosy or classify its clinical form. This article aims to update dermatologists on leprosy, through a review of complementary laboratory techniques that can be employed for the diagnosis of leprosy, including Mitsuda intradermal reaction, skin smear microscopy, histopathology, serology, immunohistochemistry, polymerase chain reaction, imaging tests, electromyography, and blood tests. It also aims to explain standard multidrug therapy regimens, the treatment of reactions and resistant cases, immunotherapy with bacillus Calmette-Guérin (BCG) vaccine and chemoprophylaxis.

Piometra canina

Pyometra occurs when bacteria colonize the uterus that is under the progesterone dominance. The diagnosis can be carried out based on anamnesis, clinical signals, physical examination and laboratory findings. The prognostic of this desease is relative when the medical therapy is used as an option. The best prevention is the surgery. The present report has an objective accomplishes a literature revision it informs on the pathology in subject gathering the available information regarding the several etiologies of that desease, diagnosis, differential diagnosis, complemental exams and treatment

Características clínicas e laboratoriais de gestantes com pré-eclâmpsia versus hipertensão gestacional

Purpose: To compare clinical and laboratory characteristics, obstetric and perinatal outcomes of patients with pre-eclampsia versus gestational hypertension. Methods: A retrospective study was carried out to analyze medical records of patients diagnosed with pre-eclampsia and gestational hypertension whose pregnancies were resolved within a period of 5 years, for a total of 419 cases. We collected clinical and laboratory data, obstetric and perinatal outcomes. Comparisons between groups were performed using the test suitable for the variable analyzed: unpaired t test, Mann-Whitney U test or χ2test, with the level of significance set at p<0.05. Results: Were evaluated 199 patients in the gestational hypertension group (GH) and 220 patients in the pre-eclampsia group (PE). Mean body mass index was 34.6 kg/m2 in the GH group and 32.7 kg/m2 in the PE group, with a significant difference between groups. The PE group showed higher systolic and diastolic blood pressure and higher rates of abnormal values in the laboratory tests, although the mean values were within the normal range. Cesarean section was performed in 59.1% of cases of PE and in 47.5% of the GH group; and perinatal outcomes in terms of gestational age and birth weight were significantly lower in the PE group. Conclusion: Women with gestational hypertension exhibit epidemiological characteristics of patients at risk for chronic diseases. Patients with pre-eclampsia present clinical and laboratory parameters of greater severity, higher rates of cesarean delivery and worse maternal and perinatal outcomes.

Taenia saginata: Differential diagnosis of human taeniasis by polymerase chain reaction-restriction fragment length polymorphism assay

Speciation of Taenia in human stool is important because of their different clinical and epidemiological features. DNA analysis has recently become possible which overcomes the problems of differentiating human taeniid cestodes morphologically. In the present study, we evaluated PCR coupled to restriction fragment length polymorphism to differentiate Taenia solium from Taenia saginata eggs present in fecal samples from naturally infected patients. A different Dral-RFLP pattern: a two-band pattern (421 and 100 bp) for T saginata and a three-band pattern (234, 188, and 99 bp) for T solium was observed allowing the two species to be separated.. The lower detection limit of the PCR-RFLP using a non-infected fecal sample prepared with a given number of T saginata eggs was 34 eggs in 2 g stool sediment. The 521 bp mtDNA fragment was detected in 8 out of 12 Taenia sp. carriers (66.6%). of these, three showed a T solium pattern and five a T saginata pattern. (c) 2005 Elsevier B.V. All rights reserved.
