Avaliação da Analgesia Após Cesariana

OBJECTIVE: The aim of this study was to evaluate the efficacy of post-caesarean analgesia comparing three techniques most frequently used. PATIENTS AND METHODS: For three months all pregnant women submitted to elective or urgent caesarean section, under general or regional anaesthesia, were evaluate with a total of 129 parturient. These parturient were divided into three groups with different techniques of postoperative analgesia: Group 1 (n = 26) received intravenous pethidine and paracetamol per os, group 2 (n = 58) received epidural morphine and group 3 (n = 45) epidural morphine and intravenous propacetamol. Pain was assessed at rest and during mobilisation using a scale of 0-without pain, 1-mild pain, 2-moderate pain and 3-severe pain. Overall satisfaction was assessed with a verbal qualitative scale of very good, good, sufficient and bad. Side effects were analysed. RESULTS: The records of pain at rest and during mobilisation were significantly lower with epidural analgesia compared with intravenous pethidine. There were no significant differences between groups 2 and 3. Similar results were observed in the degree of satisfaction. For 50% of parturient of epidural analgesia (groups 2 and 3) and only 4% of intravenous pethidine (group 1) the analgesic technique was very good. Propacetamol and epidural morphine (group 3) had better pain scores (very good and good) when compared with morphine alone (group 2) but there were no significant differences. Epidural morphine was associated with more pruritus. CONCLUSION: From this study we are able to conclude that epidural morphine offers a good quality of analgesia with better satisfaction and minimal side effects.

Decreased Vascular Endothelial Growth Factor (VEGF) Expression in Focal Segmental Glomeruloesclerosis Lesions of Patients Under Sirolimus

Background: Proteinuria (PT) with SRL appears not only after conversion from a calcineurin inhibitor (CI), but also in de novo patients. The PT may be related to a hemodynamic effect of CI withdrawal or to a direct effect of SRL in glomerulus (GL). Recently an association between PT in SRL patients and FSGS lesions has been described. It is also known that SRL decrease VEGF synthesis and experimental data suggest that VEGF is essential to podocyte survival and differentiation. Aim: To determine if glomerular lesions and PT in SRL patients could be related to altered glomerular VEGF expression. Material and methods: We evaluated glomerular VEGF expression in 10 biopsies: A-allograft kidney in backtable (n=3); B-native normal kidney (n=1); C-native kidney with FSGS lesions (n=2); D-allograft kidney with FSGS lesions from proteinuric patients under SRL after conversion from CI (n=3); E-allograft kidney in proteinuric patient under SRL with a membranous glomerulonephritis (n=1). We employed indirect immunohistochemistry in paraffin-embedded sections using a mouse monoclonal antibody against human VEGF-C1 (Santa Cruz). Results: The controls biopsies (A; B) showed normal global VEGF expression, with strong podocyte staining. The VEGF expression in the group C was similar to the controls, although no FSGS lesions were observed in the stained GL. The group D showed normal VEGF expression in the apparently normal GL, hypertrophied podocytes with reduction of VEGF in anomalous GL, and no staining in slcerotic lesions. We observed a gradual reduction of VEGF expression with progressive dedifferentiation of podocytes. In the group E the VEGF was globally reduced, with some hypertrophied podocytes expressing decreased VEGF. Conclusion: We confirmed the diminished VEGF expression in injured podocytes of SRL patients.This decreased expression may result from a direct effect of SRL and precede the appearance of FSGS lesions and PT. Further studies are needed with greater number of cases and controls, including early biopsies of patients under SRL.

Validating Regulatory Sensory Processing Disorders Using the Sensory Profile and Child Behavior Checklist (CBCL 1 –5)

The objective was to validate Regulatory Sensory Processing Disorders’ criteria (DC:0-3R, 2005) using empirical data on the presence and severity of sensory modulation deficits and specific psychiatric symptoms in clinical samples. Sixty toddlers who attended a child mental health unit were diagnosed by a clinical team. The following two groups were created: toddlers with RSPD(N = 14) and those with ‘‘other diagnoses in Axis I/II of the DC:0-3R00(OD3R) (N = 46). Independently of the clinical process, parents completed the Infant Toddler Sensory Profile (as a checklist for sensory symptoms) and the Achenbach Behavior Checklist for ages 1/2–5 (CBCL 1/2–5). The scores from the two groups were compared. The results showed the following for the RSPD group: a higher number of affected sensory areas and patterns than in the OD3R group; a higher percentage of sensory deficits in specific sensory categories; and a higher severity of behavioral symptoms such as withdrawal, inattention, other externalizing problems and pervasive developmental problems in CBCL 1/2–5. The results confirmed our hypotheses by indicating a higher severity of sensory symptoms and identifying specific behavioral problems in children with RSPD. The results revealed convergent validity between the instruments and the diagnostic criteria for RSPD and supported the validity of RSPD as a unique diagnosis. The findings also suggested the importance of identifying sensory modulation deficits in order to develop an early intervention to enhance the sensory capacities of children who do not fully satisfy the criteria for some DSM-IV-TR disorders.
