Changes in breast sensibility after reduction mammaplasty remain a controversial subject and most previous studies report only qualitative results. There is more accurate measuring of the sensibility of the skin with the Pressure-Specified Sensory Device (PSSD), which measures the pressure perception of the skin in grams per square millimeter. The evaluation of breast sensibility before and after reduction mammaplasty using the upper medial pedicle technique was undertaken in 25 patients. The PSSD was used to measure one dynamic point threshold in nine points of the breast during the preoperative period and 6 months after surgery. After surgery all patients had decreased sensation in all points studied, and this was significant. There are few reports of breast sensibility after mammaplasty using the PSSD, and the discrepancy in results reported using other methods of evaluation could be related to precision in evaluation.
On the basis of our observations, the latissimus dorsi myocutaneous flap is a consistent technique for reconstruction following conservative breast surgery. Donor-site complications are more often observed in those who are obese; they are higher risk patients.
Diabetic neuropathy is an important complication of the disease, responsible for ulceration and amputation of the foot. Prevention of these problems is difficult mainly because there is no method to correctly access sensibility on the skin of the foot. The introduction of the Pressure-Specified Sensory Device (PSSD TM) in the last decade made possible the measurement of pressure thresholds sensed by the patient, such as touch, both static and in movement, on a continuous scale. This paper is the first in Brazil to report the use of this device to measure cutaneous sensibility in 3 areas of the foot: the hallux pulp, the calcaneus, and the dorsum, which are territories of the tibial and fibular nerves. METHOD: Non-diabetic patients were measured as controls, and 2 groups of diabetic patients - with and without ulcers - were compared. The PSSD TM was used to test the 3 areas described above. The following were evaluated: 1 PS (1-point static), 1 PD (1-point dynamic), 2 PS (2-points static), 2 PD (2-points dynamic). RESULTS: The diabetic group had poorer sensibility compared to controls and diabetics with ulcers had poorer sensibility when compared to diabetics without ulcers. The differences were statistically significant (P <.001). CONCLUSION: Due to the small number of patients compared, the results should be taken as a preliminary report.
Changes in cutaneous sensibility are common after diverse plastic surgical procedures. Although prior studies examined aesthetic results, combined procedures, and new abdominoplasty techniques, few examined the effect of undermining on cutaneous sensibility. This study aimed to analyze and quantify cutaneous sensibility after classic abdominoplasty. Two groups of patients were studied: a control group of 10 patients without surgery and another group of 25 patients who had undergone classic abdominoplasty. The abdominal wall surface was divided into nine regions. Pain sensibility was evaluated by tests with needles, and thermal sensibility by test tubes containing hot and cold water. Superficial tactile sensibility was tested using the Pressure-Specified Sensory Device (PSSD), which is capable of determining the cutaneous pressure threshold. Statistical analysis was conducted using Student's 't-test'. The results showed a decrease in the three types of sensibility. Statistical analysis showed a significant difference (p < 0.05) between the groups for all regions tested. The centermost regions of the abdominal wall presented the highest index of analgesia and thermal anesthesia, as well as higher cutaneous pressure thresholds.
O receio em nosso meio, em se retardar, erroneamente, a revascularização do miocárdio (RM) em pacientes idosos determinou a realização deste estudo. Um total de 361 pacientes foram, consecutivamente, submetidos a RM entre 1992 e 1995, no InCór, dos quais 30,7% eram mulheres, 69,3% homens; 36,7% encontravam-se em classe funcional III/IV. Foi realizada análise univariada com 19 fatores perioperatórios e, a seguir, multivariada (regressão logística) com as variáveis que mostraram associação significativa (p < 0,005). Os fatores prognósticos da morbidade operatória foram: diabete melito, ICC, angina instável. Os pós-operatórios foram: acidente vascular cerebral, insuficiência renal, infecção e suporte respiratório prolongado. Concluímos que a revascularização do miocárdio pode ser realizada em pacientes com idade avançada, acompanhada de excelentes resultados (baixa mortalidade operatória) especialmente pacientes em classe funcional de ICC não muito avançada, propiciando melhora significativa da qualidade de vida.
The trend in Brazil of erroneously delaying myocardial revascularization in the elderly determined this study. Three hundred consecutive elderly patients (mean age: 73,92, standard deviation: 3.32). Between October 1992 and July 1995, 361 consecutive patients underwent isolated coronary artery bypass grafting, of whom 111 (30,7%) were females and 250 (69,35) males. There were 128 (35,5%) diabetic patients and 128 (36,7%) were in NYHA III/IV. Univariate analysis per-operatory of 19 factors followed by multivariate logistic regression analysis of the significant variables (p 0.005) were done. Major complication ocurred in 178 (49.3%) and were independent predictors of operative morbidity: Diabetes mellitus, NYHA funcional classification, urgent cases and DP2. There were 33 (9,1%) in hospital deaths, and diabetes mellitus, NYHA functional classification, unstable pre-operative angina and cerebral vascular acidents, renal failure, infection and insufficiency respiratory failure were independent predictors of operative mortality. We concluded that coronary artery bypass grafting is possible in elderly patients with a favorable outcome, especially when done in patients with normal to moderately depressed left ventricular function
