The natural history of carpal tunnel syndrome: A study of 20 hands evaluated 4 to 9 years after initial diagnosis

Carpal tunnel syndrome (CTS) is the most frequent entrapment neuropathy. In the last decade several papers have been published on epidemiology, clinical aspects, diagnosis, and treatment, but little is known about its natural history. The objective of this work was to study the natural history of CTS syndrome. From 358 patients with clinical and conduction study diagnosis of CTS, 12 cases were identified that had refused surgical treatment, had not used anti-inflammatory medications, and had not undergone orthopaedic procedures, such as immobilization or anaesthetic infiltration. These 12 patients have 20 compromised hands which have been followed up for between 4 and 9 years. In all cases sensory and motor conduction studies were performed on the median nerve, at the beginning and end of follow-up period. Electrical improvement was marked in 5 hands and slight in 3; there was no significant change in 10, and deterioration in 2. As 8 hands (7 patients) showed improved clinical symptoms and conduction studies over several years, this brings the universally accepted procedure of surgical treatment into doubt.

Systemic and local teething disturbances: Prevalence in a clinic for infants

The aim of this study was to present data as reported by parents on primary tooth eruption and the occurrence of local and systemic manifestations in children ages 0 to 3 years seen at the baby clinic of the Araçatuba Dental School, UNESP, São Paulo, Brazil. Data from 1,813 records were analyzed, yielding 1,165 records suitable for review. Some type of local and/or systemic manifestation during primary tooth eruption was reported for 95% (1,129) children studied. The predominant manifestation was gingival irritation (85%), while the least frequent symptom (26%) was a runny nose.

Labio doble congénito asociado a hemangiomas: A propósito de un caso

Double lip is a developmental abnormality which may occur either isolated or as a component of Ascher's syndrome. A case of congenital double lip associated to hemangiomas and enlargement of the thyroid is reported. The oral and facial hemangiomas were excised under local anesthesia. Surgical reconstruction of the upper lip was done in order to reduce the interference with speech and mastication. The recognition and treatment of the abnormalities are discussed.

Injeção subaracnóidea inadvertida de corticoíde em tratamento de dor crônica da coluna lombar. Relato de caso

BACKGROUND AND OBJECTIVES: Before epídural steroids were used in chronic lumbar pain, subarachnoid injection of these agents was the treatment of choice. Although still preconized by some authors, this technique may lead to severe complications with neurological sequelae. This report aimed at describing a case of accidental subarachnoid injection of steroid associated to local anesthetics during epidural puncture to treat lumbar pain. CASE REPORT: Male patient, 46 years old, followed byneuro-surgery for presenting right sciatic pain for 9 month, refractory to clinical treatment due to L 4-L 5 disk protrusion confirmed by CT scan, without neurological deficit. Epidural puncture for pain treatment was performed in L 4-L 5 with 17G needle and 10 mL solution were injected containing 4 mL of 0.25% bupivacaine, 80 mg methylprednisolone and 4 mL of 0.9% saline. Although there has not been CSF reflux, 5 minutes after injection there were sensory block in T 4 and motor block in T 6, associated to blood pressure and heart rate decrease. CONCLUSIONS: Accidental subarachnoid injections with the association of steroids for pain relief may cause adverse effects. There are several risks, varying from mild transient symptoms to nervous injuries, including spinal cord injuries. Our patient had no sequelae from the accidental subarachnoid injection, probably because it has been a single injection.

Importância da linha de base pré-exposição das colinesterases (ChEs) no controle ocupacional a praguicidas organofosforados e carbamatos

The most immediate toxic effects of a poisoning for organophosphate or carbamate are promoted by inhibition of cholinesterases (ChEs). However, a serious limitation to the diagnosis of mild organophosphate or carbamate poisoning and to preventive screening of organophosphate-exposed workers has been the large interindividual variability in ChEs activity. This makes it necessary to obtain a pre-exposure baseline measurement of enzyme activity as a basis for evaluating subsequent declines. Thus, the objective of this work is demonstrate the value of the pre-exposure baseline in the interpretation of the results of the ChEs activity of the carbamate or organophosphate-exposed workers. Using Nabb & Whitfield (1967) method to analyze blood of 48 workers the results have shown a erythrocyte cholinesterase range of 10.1 to 19.7 μmol/min/mL and plasm cholinesterase range of 2.2 to 6.9 μmol/min/mL. Despite the large interindividual variation presented, when one used the pre-exposure baseline it was possible to correlate symptoms of light poisoning of the exposure workers to carbamate with fall in the Er-ChE activity lesser then 30% of the pre-exposure baseline activity.

Liposomal daunorubicin and dexamethasone as a treatment for multiple myeloma - The DD protocol

Context and Objective: Lipasomial daunorubicin has been used to treat hematological malignancies, including multiple myelomo (MM). The goal was to evaluate efficacy, side-effects and toxicity of liposomal daunorubicin and dexamethasone (DD Protocol). Design and Setting: Prospective study of Sírio-Libonês, São Camilo, Brasil and Alemão Oswaldo Cruz hospitals. Methods: Twenty consecutive patients with active MM received four cycles of liposomal daunorubicin intravenously for two hours (25-30 mg/m 2/day) on three consecutive days per month, with oral dexamethasone, (10 mg every six hours) on four consecutive days three times a month. Results: The male/female ratio was 1:1 and median age 60. Nine patients were stage IIA, ten IIIA and one IIIB. The median from diagnosis to starting DD was 13 months. All patients received four cycles, except one. Fifteen had already received chemotherapy before DD. Responses of > 50% reduction in serum monoclonal paraprotein were observed in six patients after first cycle (30%), six after second (30%) and four after third (20%), while four (20%) did not obtain this. Initially, 17 patients (85%) had anemia: 12 (70%) achieved correction. Progressive disease was observed in three patients (15%), while one had minimal response, four (20%) partial and 12 (60%) complete. Hemotologlical toxicity was acceptable: three patients (15%) had neutrophils < 1,000/mm 3; none had thrombocyfopenia. Gastrointestinal toxicity was mild: nausea (10%), anorexio (15%) and no vomiting. Conclusions: This treatment has mild toxicity and good response rate. It may therefore be feasible before autologous bone marraw transplantation.

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.

Sertralina no tratamento de pacientes com depressão maior leve e moderada: Estudo multicêntrico brasileiro

Introduction: To evaluate the efficacy, safety, and tolerability of sertraline for the treatment of Brazilian patients with mild to moderate major depression. Patients and methods: Patients were 18 years old or older treated on an out-patient basis. Previous medications were stopped for a 2-week washout period. Afterwards, patients received sertraline, initial dose of 50 mg/day up to the 4 th week. The dose could then be increased up to 200 mg/day according to the efficacy and tolerability. Therapeutic efficacy was evaluated with the Montgomery-Asberg Depression Rating Scale (MADRS), Hamilton scale for depression (HAM-D), and Clinical Global Impression (CGI). Results: 51 patients (42 women) were evaluated regarding efficacy and safety. Treatment with sertraline significantly decreased scores of MADRS, HAM-D e ICGfrom 15.7 ± 6.1; 12.2 ± 3.9 e 3.5 ± 0.6 to 6.2 ± 6.5; 5.4 ± 4.7 e 2.3 ± 1.0 (P < 0.0001), respectively. Sertraline was well tolerated. Gastro-intestinal upset (N=14; 24.6%), headache (N=7; 12.3%), sleep alterations (H-7; 12.3%), dizziness (N-4; 7.0%), and anorexia (N=4; 7.0%) were the most common adverse events. Six patients discontinued the treatment due to adverse events. Conclusion: Sertraline is efficient and presents a favorable safety and tolerability profile for the treatment of Brazilian patients with mild to moderate major depression. © Copyright Moreira Jr. Editora.

Level of insight and clinical features of obsessive-compulsive disorder with and without body dysmorphic disorder

Introduction: Body dysmorphic disorder (BDD) and obsessive-compulsive disorder (OCD) have several similarities and are included among the obsessive-compulsive spectrum of disorders. However, the content of preoccupations and level of insight of BDD patients differ from OCD patients. Objective: To compare the level of insight regarding obsessive-compulsive symptoms (OCS) and other clinical features in OCD patients with and without comorbid BDD. Methods: We evaluated 103 OCD patients (n=25, comorbid BDD), according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria using the Structured Clinical Interview for DSM-IV, the Yale-Brown Obsessive-Compulsive Scale, the University of Sao Paulo Sensory Phenomena Scale, the Beck Depression and Anxiety Inventories, and the Brown Assessment of Beliefs Scale. Resylts: The study groups differed significantly on several clinical features, including level of insight. A worse level of insight regarding OCS was independently associated with the presence of comorbid BDD. Lower educational level, more psychiatric comorbidities, presence of somatic and hoarding obsessions, and presence of intrusive images were associated with BDD comorbidity, even after adjusting for possible confounders. Conclusion: The presence of BDD in OCD patients is associated with poorer insight into obsessional beliefs and higher morbidity, reflected by lower educational levels and higher number of psychiatric comorbid disorders in general.

Is the prevalence of asthma and related symptoms among Brazilian children related to socioeconomic status?

Objective. To evaluate the relationship between socioeconomic status (SES) and the prevalence of asthma and related symptoms among Brazilian children. Methods. The International Study of Asthma and Allergies in Childhood (ISAAC) written questionnaire was applied to 23,457 six- to seven- year-old schoolchildren (SC) and 58,144 thirteen- to fourteen-year-old adolescents (AD) from 20 Brazilian cities. SES was evaluated by infant mortality index, poverty index, and average nominal income for people older than 10 years of age. Results. Current asthma ranged from 16.5% to 31.2% among SC and from 11.8% to 30.5% among AD and severe asthma from 2.9% to 8.5% (SC) and 2.6% to 9.1% (AD). Higher values were observed in Brazilian-Northern, -Northeastern and -Southeastern centers. No significant association between SES and prevalence of asthma and related symptoms was observed. Conclusions. In Brazil, the prevalence of asthma and related symptoms is quite variable and independent of SES. Copyright © 2008 Informa Healthcare USA, Inc.

Frequency of the HFE C282Y and H63D polymorphisms in Brazilian malaria patients and blood donors from the Amazon region

Malaria is an endemic parasitosis and its causitive agent, Plasmodium, has a metabolism linked to iron supply. HFE is a gene with the polymorphisms C282Y and H63D, which are associated with a progressive iron accumulation in the organism leading to a disease called hereditary hemochromatosis. The aim of the present study was to determine the allelic and genotypic frequencies of the HFE gene polymorphisms in malaria patients and blood donors from the Brazilian Amazon region. We screened 400 blood donors and 400 malaria patients for the HFE C282Y and H63D polymorphisms from four states of the Brazilian Amazon region by polymerase chain reaction and restriction fragment length polymorphism analysis. We did not find any C282Y homozygous individuals, and the only five heterozygous individuals detected were from Pará State. The most frequent genotype in the North region of Brazil was the H63D heterozygote, in both study groups. Our results contribute to the concept that the Brazilian Amazon region should not be regarded as a single entity in South America. These polymorphisms did not influence the symptoms of malaria in the population studied, as neither severe signs nor high parasitemia were observed. Therefore, different hereditary hemochromatosis diagnostic and control measures must be developed and applied within its diverse locations. Investigations are currently being carried out in our laboratory in order to determine the importance of the coexistence of hereditary hemochromatosis in patients affected by parasitic diseases, such as malaria. ©FUNPEC-RP.

Effect of occlusion on joint sounds in asymptomatic individuals.

Occlusion is a predisposing factor for Temporomandibular Dysfunctions (TMD) of the joint, whose first sign and/or symptom is usually joint sound. To verify the effect of occlusion on joint sounds, temporomandibular joints (TMJ) were analyzed in 78 asymptomatic individuals with various dental conditions. Electrosonography was used to determine the intensity of the vibration in the temporomandibular joint (TMJ) on opening and closing the mouth. Transducers (piezoelectric accelerometer) were placed on the right and left joints. Results were tabled and analyzed using the Kruskal-Wallis test (a=0.05). It was concluded that TMJ vibration in partly edentulous individuals from Kennedy classes I, II and III is statistically higher than in dentate and fully edentulous subjects.
