Assessment of different folic acid supplementation doses for low-birth-weight infants.

AIM: The adequacy of 50 mcg folic acid supplementation given to low-birth-weight babies was investigated. The folate levels of the mothers and infants, and breastmilk, and the optimum dose for folic acid supplementation were also investigated. MATERIAL AND METHODS: After obtaining blood from 141 low-birth-weight infants on the 1st day of life for serum and red cell folate levels, the infants were randomly allocated into three groups according to the folic acid supplement dose. Forty-six infants were given 25 µg/d folic acid, 39 were given 50 µg/d folic acid, and 44 were given 75 µg/d folic acid. Folic acid could not be given to 12 infants. Follow-up blood samples were obtained at the end of folic acid supplementation. Maternal samples for red cell and serum folate levels and breast milk folate levels were obtained within the first 48 hours and the samples for measuring breastmilk folate level were obtained on the 3rd day postnatally. The feeding modes of the infants, maternal folic acid intake, and details of neonate intensive care unit course were recorded. RESULTS: The mean birth weight and gestational age of the infants were found as 1788.2±478.4 g and 33.5±2.9 weeks, respectively. The mean serum and red cell folate levels on admission were found as 21.2±12.2 ng/mL and 922.7±460.7 ng/mL, respectively. The mean maternal serum and red cell folate levels and the mean breast milk folate levels were found as 12.3±7.5 ng/mL, 845.5±301.4 ng/mL, and 30.6±33.0 ng/m, respectively. The breast milk folate levels of mothers who were supplemented with folic acid during pregnancy were significantly higher compared with mothers who were not supplemented with folic acid (p<0.001). Infants who were supplemented with folic acid had higher follow-up serum folate levels compared with the basal level in all groups, but there was no statistically significant difference between the groups. CONCLUSION: This study showed that the folic acid doses of 25, 50, and 75 µcg/d affected serum folate levels similarly. We can conclude that the dose of 25 µcg/d is adequate for low-birth-weight infants.

Effectiveness of microwave diathermy on pain, functional capacity, muscle strength, quality of life, and depression in patients with subacromial impingement syndrome: a randomized placebo-controlled clinical study.

The aim of this clinical trial was to evaluate the effectiveness of therapeutic MD on pain, functional capacity, muscle strength, quality of life, and depression in patients with subacromial impingement syndrome (SIS). A total of 40 inpatient subjects with definite SIS were included in this study. These patients were sequentially randomized into 2 groups. Group 1 (n = 20) received therapeutic MD. Group 2 (n = 20) was served as control group and received sham MD. Superficial heat and exercise program were given to both groups. Both of the programs were performed 5 times weekly for 3 weeks. Patients were assessed before treatment (BT), after treatment (AT), and at a 1-month follow-up (F). Outcome measures included visual analogue scale, goniometry, Shoulder Pain and Disability Index, Shoulder Disability Questionnaire, shoulder isokinetic muscle testing, handgrip strength, Short Form 36, and Beck Depression Index. The patients with SIS in each group had significant improvements in pain, shoulder ROM, disability, shoulder muscles and grip strength, quality of life, and depression AT and F when compared with their initial status (P < 0.05). There was no statistically significant difference between the groups according to all the parameters regarding the change scores between AT-BT test and F-BT test (P > 0.05). A 2,450-MHz MD regimen showed no beneficial effects in patients with SIS, so the superficial heat and exercise program, as it is efficient, may be preferable for the treatment of SIS, alone.

Treatment of melasma with a depigmentation cream determined with colorimetry.

BACKGROUND: Melasma is a pigmentary disorder often recalcitrant to treatment. Few studies have objectively evaluated the efficacy of treatment colorimetrically. AIM: To evaluate the safety and efficacy of a depigmentation cream, including mainly glycolic acid and Rumex occidentalis. METHOD: Twenty-seven patients applied the cream twice daily for the first 3 months and twice weekly for the following 3 months. L*, C* and h* values of the target lesions and the perilesional area were analyzed at baseline, 12 and 24 weeks colorimetrically. The physician and patient evaluated the clinical response rate. These results were compared statistically between the lesional and perilesional area. RESULTS: There was a significant difference between 0-12, 0-24 (L*, C* and h* values) and 12-24 weeks (L* value) (p <0.001). For C* and h* values, the difference was not significant between 12 and 24 weeks (p = 0.464 and 0.151, respectively). Statistical significance was detected only between 3 and 6 months for C* value (p < 0.05) for the lesional and the perilesional areas. Clinical response rate was significant (p < 0.05). CONCLUSION: Our depigmentation cream is a moderate effective agent, well tolerated and can be considered as an alternative treatment of melasma. Twice-daily application may enhance the efficacy of treatment instead of twice-weekly application in the maintenance period.

Clinical comparison of potassium-titanyl-phosphate (KTP) versus neodymium:YAG (Nd:YAG) laser treatment for lower extremity telangiectases.

BACKGROUND: The Nd:YAG laser has been considered the gold standard of treatment for leg veins, but pain and side effects have fueled physicians to use treatment alternatives. OBJECTIVE: To compare the clinical efficacy of the long-pulsed 1064-nm Nd:YAG laser with KTP laser irradiation in the treatment of leg telangiectasia. METHODS: A series of 16 patients with size-matched superficial telangiectases of the lower extremities were randomly assigned to receive three consecutive monthly treatments with the long-pulsed 1064-nm Nd:YAG on one leg and 532-nm KTP laser irradiation on the other. RESULTS: For the 16 patients who completed the study, 64 leg vein sites were treated. Average clinical improvement scores were 1.94 and 1.25 for the KTP laser-treated leg and 3.38 and 3.50 for the Nd:YAG laser-treated leg with thin (≤ 1 mm) and large (1-3 mm) vessels, respectively. After the third treatment session, average improvement scores of 2.44, 1.31 and 3.75, 3.23 were given for the KTP and Nd:YAG laser-treated sides, respectively. CONCLUSION: Both the 1064-nm Nd:YAG and KTP lasers are effective in the treatment of lower extremity telangiectases. However, the KTP laser has very low efficacy with vessels larger than 1 mm and should not be elected when treating such vessels.

Protective effects of cysteine, methionine and vitamin C on the stomach in chronically alcohol treated rats.

A chronic intake of high dose alcohol may cause oxidative stress and inflammation in the stomach. It is hypothesized that cysteine-methionine and vitamin C may neutralize harmful compounds while potentiating the antioxidant capacity of the cell or tissue. The experimental animals were fed regular diets and were maintained for 90 days in the control group, the alcoholic group, which was given 2.5 g of 50% ethanol kg(-1) body wt. administered intragastrically every other day, or the alcoholic with antioxidant supplement group, to whom 2.5 g of 50% ethanol kg(-1) body wt. + a solution that contained 200 mg vitamin C, 100 mg cysteine and 100 mg methionine was administered intragastrically every other day. After the treatments, the stomach was taken for pathological and biochemical analysis. The stomach of the alcoholic group rats had higher scores of pathological findings compared with the control group, whereas the scores of the antioxidant-supplemented group were lower than the alcoholic group. In addition, the oxidized protein and lipid content in the stomachs of the alcoholic group were significantly higher than the control, but antioxidant supplementation lowered the amount of oxidation in the antioxidant supplemented group. The amount of stomach glutathione in the alcoholic group was higher than that of the control and antioxidant-supplemented groups. Interestingly, the level of total thiol in the stomach tissue of rats with antioxidant supplement was statistically higher than that of the control and alcoholic groups. In conclusion, the scores of the pathological findings in the stomach of rats with the antioxidant supplement were lower than the chronic alcohol-treated rats, albeit the amount of total thiol was increased in this group. Moreover, chronic alcohol treatment led to an increase in the level of lipid and protein oxidation in the stomach tissue of rats. A simultaneous intake of ascorbate/l-cys/l-met along with ethanol attenuated the amount of oxidation which suggested that cysteine-methionine and vitamin C could play a protective role in the stomach against oxidative damage resulting from chronic alcohol ingestion.
