The Relation of Diabetes Type 2 with Sexual Function among Reproductive Age Women in Iran, a Case-Control Study.

Background. Diabetic patients are at the greater risk of retinopathy, nephropathy, neuropathy, and sexual dysfunction compared to the general population. Objective. The aim of this study was to evaluate the sexual dysfunction in type 2 diabetes reproductive age women in Iran. Method. This was a case-control study carried out on 130 women with type 2 diabetes and 130 healthy women. The type 2 diabetes diagnosis was confirmed with abnormal fasting blood sugar, abnormal random blood sugar test, and abnormal level of HbA1C. Eligible women were requested to complete a demographic questionnaire and female sexual function index (FSFI). The chi-square test, independent t-test, and Multivariate Analysis of Covariance (MANCOVA) were used for analyzing data. Results. Results of this study showed that diabetic women had significantly lower sexual desire, arousal, lubrication, and orgasm and more pain compared to the healthy women (p < 0.05). Also diabetic women had lower sexual satisfaction compared to the healthy women (p = 0.002). The total score of sexual function was significantly lower in the diabetic women compared to the healthy women (21.25 ± 7.04 versus 22.43 ± 7.6, p = 0.004). Conclusion. Results of this study showed that the score of all dimensions of sexual function in diabetic patients was lower than that in healthy women. Education and counseling about controlling diabetes and sexual function among diabetic women in reproductive age are recommended.

Effects of vacuum-compression therapy on healing of diabetic foot ulcers: randomized controlled trial.

A single-blind, randomized controlled trial was conducted to evaluate vacuum-compression therapy (VCT) for the healing of diabetic foot ulcers. Eighteen diabetic patients with foot ulcers were recruited through simple nonprobability sampling. Subjects were randomly assigned to either an experimental or a control group. Before and after intervention, the foot ulcer surface area was estimated stereologically, based on Cavalieri's principle. The experimental group was treated with VCT in addition to conventional therapy for 10 sessions. The control group received only conventional therapy, including debridement, blood glucose control agents, systemic antibiotics, wound cleaning with normal saline, offloading (pressure relief), and daily wound dressings. The mean foot ulcer surface area decreased from 46.88 +/- 9.28 mm(2) to 35.09 +/- 4.09 mm(2) in the experimental group (p = 0.006) and from 46.62 +/- 10.03 mm(2) to 42.89 +/- 8.1 mm(2) in the control group (p = 0.01). After treatment, the experimental group significantly improved in measures of foot ulcer surface area compared with the control group (p = 0.024). VCT enhances diabetic foot ulcer healing when combined with appropriate wound care.

Validation of Michigan neuropathy screening instrument for diabetic peripheral neuropathy.

OBJECTIVE: The reliability and accuracy of the Michigan neuropathy screening instrument (MNSI) have been discussed recently. As a result of the difficulties of performing and analyzing nerve biopsy as a standard diagnostic test, electromyography and neuronography is used as the best alternative diagnostic procedure. The objective of this study was to determine the diagnostic performance of the test characteristics and cut-off point of MNSI scoring for the diagnosis of diabetic peripheral neuropathy. METHOD: Over a 2-year period, a cross-sectional study was conducted on 176 type 2 diabetic patients. An internist carried out the MNSI and the sum of scores varying from 0 to 1 for each abnormality as revealed in foot appearance, ulceration, ankle reflexes and vibratory perception has been recorded. A neurologist, who was blind to the MNSI scores, performed all neurophysiological studies. The test performance characteristics of the MNSI procedure were measured for different cut-off values. RESULTS: MNSI scores of 1.5, 2.0, 2.5 and 3.0 were assessed as cut-off values. Sensitivities were 79%, 65%, 50% and 35% and specificities were 65%, 83%, 91% and 94%, respectively. Positive predictive values increased and negative predictive values decreased for each score. Accuracies, likelihood ratios and post-test probabilities were measured. CONCLUSION: The accuracy of MNSI scoring makes it a useful screening test for diabetic neuropathy in taking a decision regarding which patients should be referred to a neurologist for electrophysiological studies. High specificity, likelihood ratios over 5 and a moderate to good post-test probability give a high diagnostic impact for MNSI scoring. We suggest a cut-off point of 2 for the MNSI procedure. However, electrophysiological studies should be considered when the patient has signs and symptoms other than those rated by the MNSI, suggesting peripheral nerve involvement, and also because the MNSI is still just a screening test.
