Topical Nigella sativa L. product: a new candidate for the management of diabetic peripheral neuropathy.

BACKGROUND: Diabetic neuropathy is one of the most common complications of diabetes. The synthetic drugs available in the market have side effects and limitations for diabetic patients, the vast majority of whom are in the upper age group. In this regard, based on Persian medicinal sources, Nigella sativa (N. sativa) has proved to have beneficial effects on neuropathic pain and neurological disorders. In this study, the effect of N. sativa is investigated topically in patients with diabetic neuropathy. METHODS: This study was performed as a double-blind clinical trial on 120 neuropathic patients. The patients were divided into three groups. The first group received a topical N. sativa product as an ointment, the second group was given a topical placebo, and the third received 300 mg gabapentin capsules. The blindness was done in first and second groups. Diabetic neuropathy was assessed before the study using the Michigan Neuropathy Screening Instrument (MNSI). In addition, neuropathy symptoms were evaluated after the trial using the MNSI questionnaire. RESULTS: The data were elicited from the patients' answers to a number of questions in the Michigan questionnaire. There were statistically significant differences between the group that received the topical N. sativa product and the other two groups in terms of legs and feet numbness (p value = 0.001), burning pain in feet or legs (p value = 0.001), muscle cramps in feet or legs (p value = 0.001), prickling fleeing in feet or legs (p value = 0.001), hurting of the skin when the bed covers touch it (p value = 0.005), aggravated symptoms at night (p value = 0.001) and hurting feelings in the legs when walking (p value = 0.032). However, the three studied groups were not statistically different in distinguishing hot water from cold water. CONCLUSION: According to the results of this study, the topical use of N. sativa, compared to the current drugs, has acceptable improving effects on diabetic neuropathic patients.

Studying the Relation Between Medial Tibial Stress Syndrome and Anatomic and Anthropometric Characteristics of Military Male Personnel.

BACKGROUND: Medial Tibial Stress Syndrome (MTSS) is common among military recruits and to our knowledge; the factors that might put the military recruits at higher risk of incidence of MTSS are not well known. OBJECTIVES: This study was done to investigate the association between some anthropometric and anatomical factors and the prevalence of MTSS among military recruits. PATIENTS AND METHODS: One hundred and eighty one randomly selected military recruits were included in this cross sectional study. Using history taking and physical examinations they were tested for MTSS. Accordingly the subjects were assigned to the case (those with MTSS) and control groups (normal healthy subjects). Using standard guidelines, the anthropometric and anatomical criteria of the subjects were measured. The correlation between the measurements and the prevalence of MTSS was tested using statistical analysis. RESULTS: Data of all the 181 subjects with the mean age of 30.7 ± 4.68 years were Included in the final analysis. The prevalence of MTSS was found to be 16.6% (30 people). Internal and external rotation range of motion, iliospinale height, the score of navicular drop test, and the trochanteric tibial lateral length were significantly different between healthy subjects and patients with MTSS (P < 0.05). DISCUSSION: The prevalence of MTSS was relatively lower in this study comparing to other studies on military personnel. It was not probably due to type of military shoes or exercise area surface (none of them were standardized); it could be due to low intensity trainings and the long intervals between training sessions.
