Intralesional zinc sulfate 2% vs intralesional vitamin D in plantar warts: A clinicodermoscopic study

Verrucae are benign proliferations seen in skin due to infection with papillomaviruses. There are different treatment strategies for warts but all of these treatments are painful, time consuming, expensive, and recurrence is common. To evaluate and compare the efficacy of intralesional 2% zinc sulfate solution vs vitamin D3 in the treatment of plantar warts, as well as reporting the side effects. This three‐armed randomized clinical trial included 105 patients presented with plantar warts divided into three groups, 35 patients per group. The first group received intralesional 2% zinc sulfate, the second group received intralesional 2% vitamin D3, and the third group received normal saline. Four sessions were done, one every 2 weeks. At the end of the study, patients showing complete response were more in zinc group (71.4%), vitamin D3 group (62.9%) compared to saline group (40%). Most of the patients in zinc group showed severe pain during injection (48.6%), most of the patients in vitamin D3 group showed mild pain (80%), while most of the patients in saline group showed no pain (57.1%). Both intralesional 2% zinc sulfate and vitamin D3 are effective in treatment of plantar warts, with zinc sulfate being more effective.     

Androgenetic alopecia in males: a histopathological and ultrastructural study

Background  Androgenetic alopecia is a common cosmetic hair disorder, resulting from interplay of genetic, endocrine, and aging factors leading to a patterned follicular miniaturization. Microinflammation seems to be a potential active player in this process.
Aims  To study the histopathological and ultrastructural changes occurring in male androgenetic alopecia (AGA).
Patients/methods  Fifty-five subjects were included in this study (40 with AGA and 15 as normal age-matched controls). Skin biopsies from frontal bald area and occipital hairy area were subjected to histopathological examination, immunohistochemical staining for collagen I and ultrastructural study.
Results  The frontal bald area of patients showed highly significant increase in telogen hairs and decrease in anagen/telogen ratio and terminal/vellus hair ratio ( P  <   0.001). Perifollicular inflammation was almost a constant feature in early cases and showed a significant inverse correlation with perifollicular fibrosis ( P  =   0.048), which was more marked with thickening of the follicular sheath in advanced cases.
Conclusion  Follicular microinflammation plays an integral role in the pathogenesis of AGA in early cases. Over time, thickening of perifollicular sheath takes place due to increased deposition of collagen, resulting in marked perifollicular fibrosis, and sometimes ends by complete destruction of the affected follicles in advanced cases.     

Nd:YAG Laser Posterior Capsulotomy After Pediatric and Adult Cataract Surgery

We evaluated neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser posterior capsulotomy procedure with or without anesthesia in 35 pediatric eyes and 51 adult eyes. We concluded that Nd:YAG laser posterior capsulotomies in children are similar to adults in general aspects and that Nd:YAG laser capsulotomy can be performed safely and effectively in children under topical or no anesthesia.     

Aqueous humor erythropoietin levels in patients with primary open-angle glaucoma

PURPOSE: To evaluate the levels of erythropoietin (EPO) in the aqueous humor in eyes with primary open-angle glaucoma (POAG) and without glaucoma. METHODS: Levels of EPO were measured using a sandwich enzyme-linked immunosorbent assay kit in aqueous humor aspirates taken during anterior segment surgery from 45 patients, of whom 20 had POAG and 25 had senile cataract only. RESULTS: The mean aqueous humor EPO concentration in eyes with POAG (10.91+/-4.32 mU/mL) was significantly higher than that from eyes with cataract (8.24+/-1.77 mU/mL, P=0.008). There was no significant difference between the serum EPO concentrations of POAG (26.46+/-10.36 mU/mL) and the control group (24.50+/-7.59 mU/mL, P=0.468). There was no correlation (P=0.165) between the EPO aqueous humor concentration and the EPO serum concentration while there was no correlation between the EPO aqueous humor concentration and the EPO serum concentration in the control group (P=0.819). CONCLUSIONS: The aqueous humor EPO level is increased in eyes with POAG.     

Effects of Kinesio tape application to trunk isokinetic strength in female participants

ABSTRACT

The purpose of this study is to analyse the effects of KT on trunk strength with respect to different angular speeds when applied to the trunks of healthy women. Forty healthy female participants were randomly distributed into two groups: the placebo group (PG) in which placebo KT was applied and the experimental group (EG). Participants’ trunk concentric flexion and extension muscle strength were measured using an isokinetic dynamometer in two different angular speeds (60°/s ? 180°/s). In both PG and EG groups, there was no significant difference measured immediately after taping at the two angular speed values. In the measurements taken 48 h later, as regards PG trunk flexion, extension muscle strength increased significantly (p = 0.0001) at 60°/sc. angular speed while, for the EG only, the strength of trunk extension muscle increased significantly (p = 0.002). It was observed, that to ensure an increase in strength, waiting for a certain length of time was required. Lower angular speeds and short-term applied KT improved the strength of the trunk extension muscle.     

Ectasia and severe atherosclerosis: relationships with chlamydia pneumoniae, helicobacterpylori, and inflammatory markers

To date, there has been no convincing evidence for an association between Chlamydia pneumoniae or Helicobacter pylori and ectasia. In this case-control study, we have investigated the association of H. pylori and C. pneumoniae seropositivity with ectasia, severe coronary atherosclerosis, and normal vessels, which were so classified by coronary angiography. We have also evaluated the influence of these infections on inflammatory markers such as high-sensitive C-reactive protein (hsCRP) and interleukin 6 (IL-6). Of the 796 patients undergoing coronary angiography for suspected ischemic heart disease, 244 patients were recruited. Of these, 91 had normal vessels, 88 had 3 or more obstructed vessels, and 65 had ectatic vessels without atherosclerosis. Eighty-seven atherosclerotic patients (98.9%) were positive for C. pneumoniae IgG, as were 64 ectatic patients (98.5%) and 76 controls (83.5%) (P < 0.001). Forty-two atherosclerotic patients (47.7%) were positive for C. pneumoniae IgM, as were 43 ectatic patients (66.2%) and 43 controls (47.3%) (P = 0.036). Seventy-two atherosclerotic patients (81.8%) were positive for H. pylori IgA, as were 26 ectatic patients (40.0%) and 44 controls (48.4%) (P < 0.001). High-sensitive CRP levels were significantly higher in ectatic patients (5.639 mg/L) than in controls (4.390 mg/L) (P = 0.032), and IL-6 levels were significantly higher in atherosclerotic patients (33.92 U/L) than in controls (14.01 U/L) (P < 0.001). Interleukin-6 levels were higher in H. pylori seropositive patients, and hsCRP levels were higher in C. pneumoniae seropositive patients, when compared with seronegatives. We suggest that, as in atherosclerosis, C. pneumoniae infection is related to ectasia, with raised CRP levels.     

The effect of rebreathing and hyperventilation on retinal and choroidal vessels measured by spectral domain optical coherence tomography

Objective: The purpose of this study was to examine the vasoreactivity in retina and choroid of the healthy eyes in response to experimentally altered partial arterial pressure of carbon dioxide (PaCO₂) using a non-invasive technique, spectral domain optical coherence tomography (SD-OCT).

Materials and methods: The study included non-smoking participants between 18 and 35 years of age, having visual acuity of 20/20 and with no systemic and ocular diseases. At baseline, the participants breathed room air (normocapnia). Hypocapnia was created with the help of hyperventilation; for this, the participants were instructed to draw deep and quick breaths, resulting one breathing cycle per 2?s. To create hypercapnia subjects rebreathed from a 5?l bag at least 3?min. Choroidal thickness and retinal artery diameter were measured at baseline, and hyperventilation and rebreathing conditions by SD-OCT.

Results: Twenty eyes of 20 healthy subjects were included in this study. Their mean age was 24.90?±?5.32 years. Hyperventilation caused a significant reduction in choroidal thickness, compared with baseline, at all points; whereas rebreathing caused no significant change at all points. The mean diameters of the arteries were 151.80?±?7.88?μm, with a significant decline to 148.90?±?7.25?μm at hyperventilation condition and a significant increase to 153.50?±?7.88?μm at rebreathing condition (p?=?0.018, p?=?0.043, respectively).

Conclusion: This study demonstrated that, SD-OCT was a useful tool in measuring the ocular vascular response under hypercapnia and hypocapnia conditions. These findings may be helpful for further understanding the physiological nature of ocular blood flow and this preliminary study provides a basis for future studies.     

Compliance With Dyslipidemia Guidelines in Daily Practice: How Effective Is Cardiovascular Risk Prevention?

Purpose

Cardiovascular disease (CVD) due to atherosclerosis is the leading cause of early mortality and morbidity. The current European guidelines on CVD prevention in clinical practice recommend the use of the Systematic Coronary Risk Estimation (SCORE) system. The current American Heart Association guidelines recommend the use of the new pooled cohort risk assessment equations to estimate the 10-year atherosclerotic CVD risk. The purpose of this article was to investigate the compliance of dyslipidemia guidelines in daily practice in patients with dyslipidemia or who have risk factors for CVD.
