Background: Verruca vulgaris ranked 10th in the top 10 diseases in 2019 seen among the Philippine Dermatological Society training institutions. The efficacy of immunotherapy, such as intralesional zinc sulfate (ZS), for warts were reported. Considering the limited studies with promising results on verruca, a study on the efficacy and safety of intralesional zinc in the treatment of verruca was considered. Objective: This study aims to determine the efficacy and safety of intralesional 2% ZS in comparison to intralesional purified protein derivative (PPD) among adult patients with verruca vulgaris. Methods: This is a double-blind, randomized, controlled trial involving 44 patients allocated to group ZS (n=22) and PPD (n=22). Intralesional injections of ZS or PPD to the largest wart were done at weeks 0, 2, 4, 6, 8, 10. Clearance and size reduction of the target and distant wart at 12th week and recurrence at 14th week were assessed. Adverse effects were checked. Results: At the 12th week of treatment, higher proportion in group ZS patients achieved total resolution of the target lesion compared to PPD, but results were not statistically significant (29% vs. 19%). Both groups showed decline in the target lesion size. The median size reduction between the two groups showed no significant differences. Three patients from group ZS showed clearance of distant warts while none in group PPD. There was no recurrence of all previously resolved warts. Adverse reactions were pain, edema, and erythema. Conclusion Intralesional 2% zinc sulfate (29%) was efficacious and safe compared to Intralesional PPD (19%) but the difference was not statistically significant. There was clearance of distant warts in 5% of group ZS patients. The mild adverse events did not warrant discontinuation of treatment.

Zinc sulfate, which was used as zinc sulfate ophthalmic solution in herpetic keratitis, has been found to have the therapeutic effects in cutaneous and mucosal herpes simplex. We studied ta evaluate the therapeutic effect of zinc sulfate in patients with herpes simplex. Nine patients with primary herpes simplex and twenty five patient with recurrent herpes simplex were included in this study. Twenty five patients(six with primary type and nineteen with recurrent type were treated with topical applicatiion of 0.3% zinc sulfate solutiion seven to eight times a day and nine patients(three with primary type and six with recurrent type)were applied with placebo vehicle in the same way. Maintenance treatment was then given tc all these patients, first once a week for one month, and then twice a month indefinitely. The effect was assessed by the comparison of the duration of disappearance of symptoms, drying of vesicles and crust formation, and desiccation and sloughing-off of cursts, and recurrence rate between zine sulfat,e group and placebo group. The resuilts were summarized as follows : 1. In the average time of the disappearance of symptoms, drying of vesicles and crust formation, a,nd desiccation and sloughing-off of crusts, the resu1t observecl in zinc, sulfate group was shorter than that of placebo group, respectively ( p < 0.01). 2. In recurrence rate, 11.1% observed in zinc sulfate group was much lower than 80.0%i in placebo group(p . 0.01). These findings suggest that topical zinc sulfate is an effective agent for treatment and prevention of recurrence af herpes simplex infection.

BACKGROUND: It has been reported that some alopecia areata patients have zinc deficiency. There have also been several reports published concerning oral zinc sulfate therapy, with encouraging results, in some alopecia areata patients. OBJECTIVE: The purpose of this study was to evaluate the therapeutic effects of oral zinc supplementation for twelve weeks in alopecia areata patients who had a low serum zinc level. METHODS: Oral zinc gluconate (50 mg/T/day) supplementation was given to alopecia areata patients without any other treatment for twelve weeks. The serum zinc level was measured before and after zinc supplementation. A four- point scale of hair regrowth was used to evaluate the therapeutic effect of oral zinc supplementation in these patients. RESULTS: Fifteen alopecia areata patients were enrolled in this study. After the therapy, the serum zinc levels increased significantly from 56.9 microg/ to 84.5 microg/dl. Positive therapeutic effects were observed for 9 out of 15 patients (66.7%) although this was not statistically significant. The serum zinc levels of the positive response group increased more than those of the negative response group (p=0.003). CONCLUSION: Zinc supplementation needs to be given to the alopecia areata patients who have a low serum zinc level. We suggest that zinc supplementation could become an adjuvant therapy for the alopecia areata patients with a low serum zinc level and for whom the traditional therapeutic methods have been unsuccessful.

Symptomatic Zinc Deficiency occurs due to decreased supplimentation, increased consumption, and decreased bowel absorption of the zinc. We report the typical case of symptomatic zinc deficiency in a patient who received total parenteral nutrition for about 4 weeks due to chronic diarrhea. And after supplementation with oral zinc sulfate, the diarrhea stopped in a day and skin lesions disappeared completely within a week.

In order to evaluate the effect of zinc sulfate on acne vulgaris, this study was performed during 3 months' period from October, 1979 to December 31, 1979. Total number of acne patients visited at the Department of Dermatology, Han Gang Sung Shim Hospital were 130, but among them 58 patients had completed this atudy. The patients were classified in 3 groups, A, B, C, as follows. Group A (23 patients) who were treated with zinc sulfate (600mg/day) and 2. 5% benzoyl peroxide Group B (20 patients) who were treated with tetracycline (initial: 750mg/day, after 2weeks: 500rng/day) and 2. 5% benzoyl peroxide. Group C (15 patients) who were treated with only 2. 5% benzoyl peroxide. To evaluate the efficacy of treatment in these 3 groups, the number of open comedone, closed comedone, papule and pustule were counted every other week for 8 weeks. (countiuned..)

The present study has been designed as a basic study on laboratory diagnosis of giardiasis and to demonstrate a more effective method for the detection of Giardia lamblia cyst with the inherent advantages of minimizing both the number of stool examinations required and the interval of stool collections for estimating the real state of prevalence in the shortest time possible. There were 3 subject groups of 75 children each currently residing in an orphanage in Gunsan city, Jeonbuk province from which stool specimens were collected every day, every other day, and every 3 days. The procedure is as follows: Resuspend the fixed sample after fixation with SAF solution. Centrifuge the sediment for 1 min. at 2,000 rpm after straining through gauze into a tube. Divide the sediment into 3 parts and use them for direct fecal smear, formalin-ether concentration (MGL) and zinc sulfate (ZnSO(4)) floatation techniques. The results are summarized as follows: Overall infection rate after 10 trials showed a 60 percent positive indication. The positive rate among children under 4 years old was significantly higher than the rate in children over 4 years old. No significant difference in rate by sex was observed. The results of examinations by direct fecal smear and MGL techniques appeared more accurate than that obtained by ZnSO(4) floatation method as indicated by a higher positive rate. Of all three methods concerned, combinations of two demonstrated a higher positive rate than that shown by any one alone. In three consecutive examinations under varying conditions such as different days, the cyst detection rate by MGL technique indicated 83 percent. In 5 examinations under the same varying conditions, the indicated rate was 94 percent. The interval of stool collection proved to be insignificant for the cyst detection rate. In conclusion, both MGL method and modified fecal direct smear can provide a good cyst detection rate of G. lamblia provided that more than 3 consecutive examinations of stool under varying conditions are carried out.
