Efficiency of hypericum perforatum, povidone iodine, tincture benzoin and tretinoin on wound healing.

Different topical agents have been used to accelerate wound healing. The purpose of this study is to compare the safety and efficacy of topical application of the extract of Hypericum perforatum (HPE), povidone iodine (PI), tincture benzoin (TB) and tretinoin (T) on surgical wound healing. Ten adult female, Wistar albino rats were included in the study. HPE, PI, TB and T solutions were applied on the wounds. After seven days, tissue samples were collected and inflammatory cells, re-epithelialization, granulation tissue, angiogenesis, collagen accumulation, hemorrhage and lysis of cells were investigated histopathologically. No dermal toxicity was noted. HPE, TB, PI have all showed good epithelialization and granulation, but HPE showed the most advanced stage of healing within a short period of time. HPE had significantly higher values of re-epithelialization and collagen accumulation, but lower inflammatory cell count and granulation tissue. TB had the second best in re-epithelialization, collagen accumulation and the highest granulation tissue. PI induced better reepithelialization and granulation than the control group with remarkable cell lysis. As a result, HPE can be a safe, effective, and cheap agent that can be used for surgical wounds.

Attractive Versus Golden Ratios: Formula of Utopian Beauty through Comparison of Facial Proportions among Worldwide Celebrities and Average People.

INTRODUCTION: Beauty criteria change according to trends, cultures, and expectations. So, the golden ratios are not enough to understand the actual beauty concept. OBJECTIVE: It is aimed to create a method and formula to define beauty in terms of different facial measurements and ratios as variables. METHODS: Frontal view photographs of 50 celebrities and 50 volunteers (female [ n = 70] and male [ n = 30]) were obtained. Thirty-three specific facial points were used. Fifty-nine measurements of distances between those points and ratios of those distances are used as statistical variables. Mean values of those variables for celebrities are compared with all participants.Then, ''total beauty score'' using statically significant differences is defined. Points according to the importance level of interested value are assigned; 1 point for a significance of 0.001 ≤ P < 0.05 and 2 points for P < 0.001. Possible independent variables for the prediction of Utopian Beauty Score were determined using linear regression analysis. Finally, 10 variables (6 measurements and 4 ratios) are used to determine a formula for beauty. RESULTS: In celebrities, the distance between head apex and hair border, lower lip vertical length, the distance between brow medial borders and forehead vertical length were higher than the average population ( P < 0.001, 0.023, 0.034, 0.001, respectively). However, the width of columella, a length between bilateral ala nasi, horizontal face, and vertical nose length, and the distance between brow apexeyelash line were shorter ( P = 0.005, < 0.001, < 0.001, < 0.001, < 0.001, respectively). Some study variables had severely significant correlations with the total beauty point (M29, r = -0.744, P < 0.001; R19, r =-0.745, P < 0.001; and R30, r = -0.735, P < 0.001). The linear regression formula for Utopian Beauty Score was determined according to statistically significant variables as y = 86.5 - 3.6 M5 + 8.1 M14 + 11.1 M20 - 6.4 M25-8.7 M29-10.3 M30-15.6 R19 + 9.3 R20 + 16.4 R25 + 18.3 R26. CONCLUSIONS: A large forehead, small nose with lifted tip, plump lip, brows with lateral apex, well-spaced eyes, and ovoid, elliptical face lines are seem to be more attractive. Additionally, a method to create a formula for beauty with variables of different measurements and ratios of facial points are determined.

Bedside approach in the diagnosis obstructive sleep apnea using postprandial oximetry testing: A comparative study with polysomnography.

INTRODUCTION: Due to the availability and cost issues in developing countries of polysomnography (PSG), there is a need for outpatient test for an initial assessment of the patients with suspected obstructive sleep apnea (OSA). OBJECTIVES: Epworth sleepiness scale (ESS) is a widely used and best-validated scale for assessing daytime sleepiness, including dozing when sitting quietly after a lunch (no alcohol). This study introduces a novel screen test called postprandial oximetry test (POT) used during daytime. METHODS: This single-center prospective study included 101 patients (80 patients with suspected OSA and 21 patients without OSA suspicion). Berlin Questionnaire was used to determine the score/pretest probability of OSA patients, all chosen randomly. First, all the patients underwent POT in laboratory. Then we performed PSG. After lunch, while sleeping, the patients were monitored for 1 hour with pulse oximetry and standard electroencephalographic system. The oximetry saturation classification events with SpO2 was divided into two groups as normal or mild obstructive sleep apnea syndrome (OSAS), and moderate-to-severe OSAS. Below 90% SpO2 drops in a postprandial oximetry recordings were accepted as moderate-to-severe. RESULTS: The mean lowest oxygen saturation in PSG was 82.34 ± 5.99, while it in POT were 87.42 ± 1.39. A positive correlation was found between POT- and PSG-derived Apnoea-Hypopnoea Index (AHIs). The sensitivity and specificity in postprandial oximetry were 85% and 85.7%, respectively. The accuracy was 0.903 for POT. CONCLUSION: POT may be useful as an outpatient test in the initial assessment of the patients with suspected OSA, serving as a gatekeeper for PSG.

Olfactory dysfunction in spondyloarthritis.

OBJECTIVE: Spondyloarthritis (SpA) is a group of disorders characterized by inflammatory arthritis including ankylosing spondylitis, psoriatic arthritis, reactive arthritis and arthritis-related inflammatory bowel diseases. Recently it has been shown that arthritic disorders are accompanied by olfactory dysfunction. We aimed to specifically investigate the association between spondyloarthritis and olfactory impairment. MATERIALS AND METHODS: Fifty individuals with SpA and 50 healthy volunteers were included in the study. Olfactory function was evaluated using the "Sniffin' Sticks" test battery. Additionally, effects of age, gender, activity of the disease, HLA-B27 status, medications, and the duration of disease were included in the analysis. RESULTS: SpA patients showed significantly lower scores for odor threshold (T), odor discrimination (D) and odor identification (I) than healthy controls (all p < 0.001). In addition, olfactory loss was negatively correlated with the presence of HLA-B27 (Human Leukocyte Antigen), but not with the current activity of the disease (Bath Ankylosing Spondylitis Activity Index). Neither medication nor duration of the disease had a significant effect on the results. CONCLUSION: SpA is associated with olfactory loss. Future studies will show whether olfactory function relates to the prognosis of SpA.

Protective Effect of Selenium Against Cisplatin-Induced Ototoxicity in an Experimental Design.

Cisplatin is an effective chemotherapeutic agent in the treatment of several types of malignant solid tumors but its clinical use is associated with ototoxicity. In the present study, we investigated the effect of selenium administration on lipid peroxidation (malondialdehyde [MDA]) and cisplatin-induced ototoxicity in rats. Healthy wistar albino rats (n = 21) were randomly divided into 3 groups: control (C), cisplatin (Cis), cisplatin and selenium (Cis+Se). Cisplatin was administered for 3 days to Cis and Cis+Se groups. Cis+Se group received selenium 5 days before cisplatin injection and continued for 11 consecutive days. Hearing thresholds and lipid peroxidation (MDA) levels of the rats were recorded before injections and at the end of experimental protocol. The cochleas of animals were harvested for histologic and immunuhistochemical examinations. In biochemichal analyses, pretreatment with selenium prevented the elevation of MDA levels in Cis+Se group rats. Moreover, animals in Cis+Se group had better hearing threshold levels than animals in cis group. Samples obtained from the animals in Cis group revealed extensive loss of the normal microarchitecture of the organ of Corti. On the other hand, animals in Cis+Se group exhibited a preservation of the morphology of the organ of Corti and outer hair cells. In the immunohistochemical examinations of cochlear tissues stained with anti-caspase-3, a higher degree of immunopositivity was found in the Cis group. When Cis+Se group and Cis group were compared, significantly less immunopositivity occurred in the Cis+Se group (P < 0.05). Thus, it appears that pretreatment with selenium may reduce cisplatin-induced ototoxicity in rats.

Laryngopharyngeal Reflux Has Negative Effects on Taste and Smell Functions.

OBJECTIVE: We evaluated the halimetric, olfactory, and taste functions of patients with laryngopharyngeal reflux (LPR). STUDY DESIGN: Prospective clinical study. SETTING: Multicenter tertiary care hospital. METHODS: Patients who were diagnosed with LPR for the first time on the basis of a Reflux Finding Score (RFS) >11 and a Reflux Symptom Index (RSI) >13 were enrolled in this study. A control group was selected from patients without a complaint of LPR. OralChroma was used for the halimetric measurement; Sniffin' Sticks were used for the smelling test; Taste Strips were used for the taste test; and monosodium L-glutamate was used for the umami test. RESULTS: A total of 110 subjects were included, with a mean age of 36.8 ± 10 years (range, 19-57 years). The differences in odor threshold scores were significant between the groups (P < .001), but no change was detected for the odor identification or discrimination scores between the groups. Bitter taste scores were significantly diminished in the reflux group compared with those in the control group (P = .001), whereas no impairments were found in the other taste scores (sweet, salty, and sour). The reflux group had significantly higher umami taste scores than those of the control group for the posterior tongue and soft palate anatomic sites (P < .001 and P < .001, respectively). Dimethyl sulfite levels were significantly higher in the reflux group than in the control (P = .001). CONCLUSION: Questioning patients who present with halitosis, taste, or smelling disorders is important to diagnose LPR.

Are temporomandibular disorders associated with habitual sleeping body posture or nasal septal deviation?

Numerous factors can be considered for the etiology of temporomandibular disorders (TMD). The aim of the present study was to investigate whether the presence of both nasal septal deviation (NSD) and habitual prone sleeping posture (HPSP) predisposes TMD. We evaluated 200 subjects in 4 groups. Group I (NSD-, HPSP-/control group), Group II (NSD+, HPSP-), Group III (NSD-, HPSP+), Group IV (NSD+, HPSP+). All patients were examined according to the research diagnostic criteria to determine the presence of TMD. Group IV had the highest value for TMD incidence (44 %). Thus, we found that the presence of both NSD and HPSP parameters increased TMD incidence in Group IV compared to the control group (p = 0.000). Additionally, Group IV showed significantly higher values than Group II (p = 0.012) and Group III (p = 0.039). For Group III (NSD-, HPSP+), TMD was determined higher compared to the control group (p = 0.009). A statistically higher value of presence of TMD was determined in Group II (NSD+, HPSP-) than control group (p = 0.029). The incidence of TMD was significantly higher in women than men (p = 0.020). We concluded that one having an unilateral obstructive nasal septal deviation in addition to a habit of sleeping in prone position must be alert for potential TMD.

Aesthetic analysis of the ideal eyebrow shape and position.

The aesthetic importance of the eyebrow has been highlighted for centuries. In this paper, we investigated ideal eyebrow. Eyebrows and eyelids, varies among different races, ages and genders. It is considered to be of primary importance in facial expression and beauty. We present one form of the ideal eyebrow aesthetic and discuss methods of optimising surgical results. For the modern acceptable concept of the ideal brow, the medial brow should begin on the same vertical plane as the lateral extent of the ala and the inner canthus and end laterally at an oblique line drawn from the most lateral point of the ala through the lateral canthus. The medial and lateral ends of the brow lie approximately at the same horizontal level. The apex lies on a vertical line directly above the lateral limbus. Individual perceptions and expectations also differ from person to person. The brow should over lie the orbital rim in males and be several millimetres above the rim in female. Male tend to have a heavier, thicker brow with a little arch present. There are some pitfalls in brow aesthetics. Overelevation creates an unnatural, surprised and unintelligent look which is the most common surgical mistake in brow lifting. Medial placement of the brow peak would create an undesired 'surprised' appearance. Moreover, a low medial brow with a high lateral peak induces an angry look. Overresection of the medial brow depressors may lead to widening and elevation of the medial brow, which creates an insensitive look and can also lead to glabellar contour defects. It is impossible to define an ideal eyebrow that is suitable for every face. However, one must consider previously described criteria and other periorbital structures when performing a brow surgery.

Olfactory and gustatory dysfunction in Myasthenia gravis: A study in Turkish patients.

OBJECTIVE: Myasthenia gravis (MG) is commonly viewed as a muscle disorder. Less is known about neurosensory function and dysfunction in MG. We aim to evaluate olfactory and gustatory behavior in Turkish patients with MG, and compare these results with age and sex-matched healthy controls. MATERIAL/METHODS: 30 individuals with MG, and 30 healthy volunteers were studied. Olfactory function was studied with the Sniffin' sticks test. Taste strip test was used for studying taste function. The t-test was used for analyzing continuous variables, and the chi-square test for categorical data. Clinical staging and medication status were included in a model analyzed using analysis of variances. RESULTS: MG patients showed significantly lower olfactory (p<0.001) and gustatory scores (p<0.001) than the healthy controls. In addition, olfactory loss correlated with the severity of the disease. Medications for MG did not influence these results. CONCLUSION: This study replicates the olfactory dysfunction found elsewhere in MG. Further, gustatory dysfunction, an activity unrelated to muscle strength, was also unveiled. Medications used for treating MG must not be blamed for the chemosensory dysfunction found in this neurological disorder.

Evaluation of the clinical effects of isotretinoin on chronic rhinosinusitis.

OBJECTIVES: This study aims to evaluate the clinical effects of isotretinoin (13-cis-retinoic acid), a derivative of retinoic acid, on the clinical features of chronic rhinosinusitis. PATIENTS AND METHODS: The study group included 25 chronic rhinosinusitis patients (16 females, 9 males; mean age 25.2 ± 6.8 years; range 15 to 25 years) who were on isotretinoin for acne treatment, while the control group consisted of 25 chronic rhinosinusitis patients (15 females, 10 males; mean age 25.2 ± 6.8 years; range 15 to 25 years) who were not on isotretinoin treatment. The patients' symptom scores in visual analog scale (VAS), Lanza and Kennedy nasal endoscopic scores and Newman computed tomography (CT) scores were obtained in order to evaluate the their symptom, examination and radiological findings. These patients' symptom and examination results were evaluated first day, week two and at months 3-5 and 6-10. Paranasal sinus CT results were studied first day and at months 6-10. RESULTS: In the group of patients being administered isotretinoin, no significant change in the mean symptom and examination scores was detected during the acute phase (week 2), while there was a significant regression in the long-term (months 3-5 and 6-10). There was a significant regression in the mean CT score after isotretinoin therapy. In the control group no significant change was seen in any of the scores. The number of acute sinusitis attacks were significantly lower in the isotretinoin group than in the control group. No significant difference was found between the two groups in terms of the duration of the healing period of acute sinusitis attacks. CONCLUSION: We conclude that the long-term administration of isotretinoin has positive effects on the clinical results of chronic rhinosinusitis.
