Factors Affecting Success Rates in Endoscopic Repair of CSF Rhinorrhea.

Objectives: Our aim in this study is to assess the effect of factors such as age, etiology, defect size, application of lumbar drainage and surgical technique on Cerebrospinal Fluid (CSF) fistula repair success rates. Methods: The Electronic Medical Records (EMR) system of our clinic was retrospectively reviewed for cases that were operated between 2006 and 2020 for CSF fistula originating from anterior skull base with endoscopic transnasal technique. A total of 35 patients were included in the study. Patients were grouped according to the number of layers used in repair (two, three or four-layered reconstruction) and defect size (smaller than 5 mm, 5 to 10 mm and larger than 10mm), etiology, location of the defect and application of lumbar drainage as LD (+) and LD (-). Complications and CSF leak recurrence were compared between groups. Results: Recurrence rates in patients who had 2 layered reconstructions were significantly higher compared to patients who had 3 or 4 layered reconstructions (p=0.049). The recurrence rate in LD (+) group (41.7%) was significantly lower compared to LD (-) group (4.3%) (p=0.012). There were no significant difference in recurrence rates between groups in terms of age, defect size, defect location and etiology. Conclusion: In endoscopic transnasal repair of anterior skull base-derived bos fistulas, planning the reconstruction at least 3 times and applying lumbar CSF drainage increases the success rates.

Alterations in the tear film and ocular surface in pediatric migraine patients.

PURPOSE: To evaluate the ocular surface (OS) parameters in the pediatric migraine patients (PMPs). METHODS: This prospective case-control study consisted of 51 PMPs (PMP group) and 55 healthy pediatric patients (HPP group). In all participants, tear function was evaluated subjectively using the Ocular Surface Disease Index (OSDI) questionnaire, objectively using Schirmer tear test (STT) and tear film disintegration time (TBUT), and with clinical and laboratory examinations (conjunctival impression cytology). The PMP group was subdivided into two groups according to their aura. RESULTS: The mean age and gender distribution of the study groups were almost the same ( P > 0.05 for both of them). In the PMP group, both the STT value and the TBUT value were significantly lower than those determined in the HPP group ( P = 0.021 and P = 0.018, respectively). In the PMP group, the OSDI scores were higher than those in the HPP group ( P = 0.032). In the PMP group, the goblet cell density values were lower than those in the HPP group ( P = 0.01). With regard to the aura, the TBUT and STT values were nonsignificantly lower in the PMP aura-positive group than in the PMP aura-negative group ( P > 0.05 for both of them). The OSDI assessment was similar in both the groups. With regard to the goblet cell count, it was observed to be less in the PMP aura-positive group than in the PMP aura-negative group ( P = 0.01). CONCLUSION: Influence of OS in children with migraine was also demonstrated using the samples taken from the conjunctiva. These changes were also demonstrated by objective tests such as STT and TBUT. Both clinical objective evaluations and pathologic changes were more prominent in the migraine with aura group.

Expression analysis of novel long non-coding RNAs for invasive ductal and invasive lobular breast carcinoma cases.

AIM: Long non-coding RNAs (LncRNAs) serve as important regulatory molecules of gene expression and protein functionality at multiple biological levels, and their deregulation plays a key role in tumorigenesis including in breast cancer metastasis. Therefore, in this study, we aim to compare the expression of novel lncRNAs in the landscape of invasive ductal carcinoma (IDC) and invasive lobular (ILC) carcinoma of breast. MAIN METHODS: We have designed an in-silico approach to find the lncRNAs that regulate the breast cancer. Then, we used the clinical samples to carry out the verification of our in silico finding. In the present study, the tissues of breast cancer were deparaffinized. RNA was extracted by the TRIzole method. After synthesizing cDNA from the extracted RNA, expression levels of lncRNAs were analyzed by qPCR using primers specifically designed and validated for the targeted lncRNAs. In this study, breast biopsy materials from 41 female patients with IDC and 10 female patients with ILC were examined histopathological and expression changes of candidate lncRNAs were investigated in line with the findings. The results were analyzed using IBM SPSS Statistics 25 version. RESULTS: The mean age of the cases was 53.78 ± 14.96. The minimum age was 29, while the maximum age was 87. While 27 of the cases were pre-menopausal, 24 cases were post-menopausal. The number of hormone receptor-positive cases was found to be 40, 35, and 27 for ER, PR, and cerb2/neu, respectively. While the expressions of LINC00501, LINC00578, LINC01209, LINC02015, LINC02584, ABCC5-AS1, PEX5L-AS2, SHANK2-AS3 and SOX2-OT showed significant differences (p < 0.05), the expressions of LINC01206, LINC01994, SHANK2-AS1, and TPRG1-AS2 showed no significant differences (p > 0.05). In addition, it was determined that the regulation of all lncRNAs could be able to involve in the development of cancer such as the NOTCH1, NFKB, and estrogen receptor signalings. CONCLUSION: As a result, it was thought that the discovery of novel lncRNAs might be an important player in the diagnosis, prognosis and therapeutic development of breast cancer.

Surgical landmarks for identification and preservation of the internal branch of the superior laryngeal nerve.

OBJECTIVE: To determine the topographical anatomic features of the internal branch of the superior laryngeal nerve (ibSLN) at the thyrohyoid membrane entrance area in relation to certain consistent anatomical structures. MATERIALS: METHODS: Twenty-two fresh adult head cadavers (9 male, 13 female; age range 52-95 years) with no signs of abnormality in the neck were dissected to determine the anatomic relationship of ibSLN and superior border of thyroid cartilage, thyroid notch, carotid bifurcation, hyoid corpus, and hyoid greater cornu. RESULTS: The topographical relationship between ibSLN and superior border of thyroid cartilage, thyroid notch, carotid bifurcation, hyoid corpus, and hyoid greater cornu was identified bilaterally in all cadavers. According to the measures, danger zone and safe zone areas for surgical could be predicted and for surgical manipulations as well. CONCLUSION: We provided the surgical anatomy and important landmarks for determining the internal branch of superior laryngeal nerve in the thyrohyoid membrane entrance region to avoid surgical damage during surgeries of this region.

Comparison of the Otolaryngological Symptoms of Laboratory-Confirmed and Clinically Diagnosed COVID-19 Patients.

Objectives: Our aim is to determine prevalence, severity, duration of otorhinolaryngologic symptoms related to coronavirus disease 2019 (COVID-19), and correlation between the test results obtained by oronasopharyngeal swab and the symptoms of these regions by evaluating differences in ear, nose, and throat (ENT) symptoms between laboratory-confirmed COVID-19 patients and clinically and computed tomography (CT)-diagnosed COVID-19 patients. Methods: The study enrolled patients with a positive polymerase chain reaction (PCR) test diagnosed with COVID-19 that grouped as PCR (+), and those with repeated negative PCR tests but COVID-19 Reporting and Data System (CO-RADS) chest CT findings with high (CO-RADS 5) or very high (CO-RADS 6) similarity to COVID-19 that grouped as PCR(-)/CT(+). Demographic features, general symptoms, and otorhinolaryngological symptoms and severity of disease were evaluated and compared. Results: The most common ENT symptoms in the PCR(+) group were loss of taste (n=77), loss of smell, and sore throat with respective frequencies of 34.5%, 31.8%, 26.0%, and in PCR(-) CT (+) group loss of taste, loss of smell, and sore throat with respective frequencies 24.6%, 21.1%, and 18.4%. ENT symptom rates were found higher in PCR (+) group (65.0%) according to PCR(-)/CT(+) group (49.1%) with statistically significant difference (p=0.008). Loss of smell rates were found higher in PCR (+) group according to PCR(-)/CT(+) group with statistically significant difference (p=0.037). Conclusion: Loss of smell and taste were most common ENT symptoms in laboratory-confirmed COVID-19 cases. The presence of COVID-19 should definitely be considered in patients presenting with sudden loss of smell or taste. In addition, loss of smell and otolaryngologic symptoms were more common in laboratory-confirmed COVID-19 according to clinically and computed tomograpy diagnosed COVID-19 cases. There can be a correlation between positive sample region and symptom region. Location of symptoms must be considered for decision of sampling location.

The effect of carbamazepine, which increases oestrogen destruction, on the endometriotic implants; an experimental rat model.

We planned this experimental study to investigate the effect of carbamazepine (CMZ) on the endometriotic implants. Rats were randomised into four groups after endometriosis surgery. Drinking water was given to the sham group, 0.2 mg/kg oestradiol valerate (EV) to the EV group, 100 mg/kg/day CMZ to the CMZ group, and 0.2 mg/kg EV and 100 mg/kg/day CMZ to the EV-CMZ group. The endometrium of the rats using CMZ stained more intensely with cytochrome P450-3A4 (CYP3A4) enzyme. No endometrial hyperplasia was found in these rats. Endometriotic implants weight was found to be higher in these rats. There was no difference between the groups in terms of staining of the endometriotic implants with CYP3A4 enzyme. Endometriotic implants were less stained with the CYP3A4 enzyme than the endometrium. According to our results, CMZ does not increase the destruction of oestrogen in the endometriotic implants, unlike the endometrium. It may even cause the lesion to enlarge.Impact statementWhat is already known on this subject? Endometriosis is an oestrogen-dependent, progressive disease. Carbamazepine (CMZ) is known to increase oestrogen degradation by activating the cytochrome P450-3A4 (CYP3A4) enzyme. CMZ can be used in the treatment of endometriosis because it increases oestrogen breakdown in tissues.What do the results of this study add? CMZ can protect the endometrium against hyperplasia by increasing the amount of CYP3A4 enzyme in the endometrium. This effect could not be demonstrated in the endometriotic implants. The presence of CYP3A4 enzyme less in the endometriotic implants than in the endometrium may explain this situation. In addition, the fact that CMZ does not increase the enzyme in the endometriotic implants may contribute to this situation.What are the implications of these findings for clinical practice and/or further research? CMZ may not be a suitable alternative in the treatment of endometriosis. However, it may protect against endometrial hyperplasia. Clinical studies are needed for this effect.

Carbamazepine protects the endometrium against negative effects of estrogen in rats.

Carbamazepine (CMZ) increases estrogen metabolism by inducing cytochrome P450 (CYP3A4). We investigated whether CMZ is protective against endometrial hyperplasia (EH). We used 32 female Wistar albino rats divided into four equal groups: the control group received drinking water, the estradiol valerate (EV) group was given EV, the CMZ group was given CMZ, and the EV + CMZ group was given both EV and CMZ. After 30 days the uteri of the rats were removed and serum estrogen and progesterone levels were measured, and endometrial tissue characteristics were evaluated. CYP3A4 expression was assessed using immunohistochemistry. Serum estrogen levels were lowest in the EV group and highest in the CMZ group. Serum progesterone levels were similar among all groups. Glandular density, a proxy measure of EH, was highest in the EV group and lowest in the EV + CMZ group. EH was detected in six of eight rats (75%) in the EV group and two of eight rats (25%) in the EV + CMZ group. Immunohistochemical staining revealed no significant difference in CYP3A4 expression among the four groups. CMZ reduced the negative effect of high dose estrogen that is not balanced by progesterone on the endometrium in rats. The effect likely is probably due to the CYP3A4 enzyme activator effect. CMZ may be protective against EH in high risk women, although confirmation is required.

What Is the Long-Term Findings of Olfactory and Taste Loss due to COVID-19?

Objectives: The objective of this study was to determine prevalance, severity, course, and long-term findings of smell and taste disorders of coronavirus disease 2019 (COVID-19) patients in mild-moderate and severe-critical disease spectrum. Methods: All adult patients conducted in our hospital with positive severe acute respiratory syndrome coronavirus 2 between March and April 2020 were surveyed during disease course and those with olfactory and taste loss were re-surveyed to determine the course and progress of these symptoms after at least 12-month follow-up. Demographic features and clinical findings were evaluated as well as disease severity. Results: A total of 77 patients with smell and/or taste loss symptoms were included in the study. At diagnosis, 58 (75.3%) patients had loss of smell and 75 (97.4%) had loss of taste. After a follow-up period of 12-14 months, 12 (15.6%) patients had ongoing loss of smell and six (8%) patients had ongoing loss of taste. Three (3.9%) patients complained of cacosmia and 5 (6.5%) complained of parosmia at follow-up. The presence of ongoing visual analog scale scores of smell and/or taste was not statistically significant between male and female patients. When presence and severity of symptoms were compared by disease severity, no statistically significant difference was found. Conclusion: Smell and taste loss seem to be among the presenting symptoms of COVID-19. The prognosis and the treatment of the smell loss and taste loss in COVID-19 patients remains unclear. To improve and accelerate recovery, the pathophysiology and the treatment options must be validated.

Histopathological Examination of the Mucosal Effects of Obstetric Gel on Vaginal Wound Healing in an Incision-Inflicted Rat Model.

Background and objective The present study intended to investigate the histopathological efficacy of obstetric gels on the healing of vaginal lacerations in rats. To the best of our knowledge, this is the first such study. Materials and methods Twenty-one female Wistar albino rats were divided into three groups, comprising seven animals per group. The first group (group 1) was the control group, the second (group 2) was the polyvinyl iodine (PI) group, and the third group (group 3) was the obstetric gel (OG) group. In all three groups, a vaginal incision was made with a No. 10 scalpel, and the incision site was sutured with a 3-0 Vicryl suture. In the control group, the incision site was left for routine healing. The incision site was washed with PI in the PI group and with OG in the OG group. After 15 days, vaginal tissues were obtained from all three groups for histopathological examination. In addition, immunohistochemistry staining was performed using caspase 3 and fibrillin 1 antibodies. Results There was no significant difference between the groups in terms of congestion, vascular proliferation, and inflammation stages in the examinations performed on the vaginal wall. However, the amount of collagen and elastic fibers increased during the remodeling and fibrosis phase, and the fibrillin 1 score increased in immunohistochemistry staining (p < 0.001). Conclusion It has been shown in rat vaginal tissue that obstetric gels do not have negative effects on wound healing; however, they contribute to wound healing by positively affecting the fibrosis stage.

Turkish Guideline for Diagnosis and Treatment of Allergic Rhinitis (ART).

OBJECT: To prepare a national guideline for Otorhinolaryngologist who treat allergic rhinitis patients. METHODS: The study was conducted by three authors, namely the writing support team. The support team made the study plan, determined the writing instructions, chose the subgroups including the advisory committee, the advisors for authors and the authors. A workshop was organized at the very beginning to explain the details of the study to the team. Advisors took the chance to meet their coworkers in their subgroups and determined the main headings and subheadings of the guideline, together with the authors. After key words were determined by the authors, literature search was done in various databases. The authors keep in touch with the advisors and the advisors with the advisory committee and the support group at every stage of the study. National and International published articles as well as the abstracts of unpublished studies, imperatively presented in National Congresses, were included in this guideline. Only Guideline and meta-analyses published in last seven years (2013-2017) and randomized controlled studies published in last two years (2015-2017) were included. After all work was completed by the subgroups, support team brought all work together and edited the article. RESULTS: A detailed guideline about all aspects of allergic rhinitis was created. CONCLUSION: The authors believe that this guideline will enable a compact and up-to-date information on allergic rhinitis to healthcare professionals. This guideline is the first in the field of Otolaryngology in Turkey. It should be updated at regular intervals.

Nasal Sprays Containing Mometasone Furoate for Relief of Post-Adenotonsillectomy Pain in Children: A Prospective Controlled Study.

OBJECTIVES: Adenotonsillectomy is one of most common surgeries performed in childhood. Post-operative pain associated particularly with tonsillectomy is still a problem for many physicians. Despite advances in surgical techniques, analgesics, or anti-inflammatory drugs, no unique strategy for post-tonsillectomy pain management has been suggested. The aim of this study is to investigate the analgesic effect of steroid containing nasal spray applied to tonsillar region after tonsillectomy. METHODS: Eighty-two patients were assigned into two groups as study and control. In study group, nasal spray containing steroid was applied to each tonsillar region after surgery for 5 days. Post-operative pain of all patients was assessed using a visual analog scale and results were compared. RESULTS: Pain decreased gradually over time in both the study and control groups. Although the pain scores from 4 h post-surgery to post-operative day 5 were not found to significantly decrease in children that used nasal spray containing steroid, these patients developed less pain on post-operative day 5,with statistical significance (p<0.05). CONCLUSION: Post-tonsillectomy pain was reported to increase around post-operative day 5, which coincides with the time of intense wound inflammation. Therefore, significant pain reduction on post-operative day 5 observed in children that used nasal spray with steroid may have clinical importance for overcoming this problem.

Transient receptor potential melastatin 2 ion channel activity in ovarian hyperstimulation syndrome physiopathology

Background/aim: Ovarian hyperstimulation syndrome (OHSS) is a complication of ovarian stimulation with increased vascular endothelial growth factor (VEGF) and vascular permeability in the ovarian tissue. Transient receptor potential melastatin 2 (TRPM2) is known to be associated with angiogenesis and vascular permeability. In this experimental study, we aimed to investigate the activity of TRPM2 in the development of OHSS. Materials and methods: Fourteen immature female rats were divided into two groups. Group 1 was the control group, and Group 2 was the OHSS group that was exposed to 10 IU of subcutaneous application of FSH for four days and 30 IU of human chorionic gonadotropin (hCG) on the 5th day. At the end of the experiment, the ovaries were removed. The right ovarian tissues were stored in 10% formol for histopathological and immunohistochemical examination. The left ovarian tissues were stored at ­80 °C for biochemical examinations. VEGF, tumor necrosis factor-alpha (TNF­α) and malondialdehyde (MDA) levels were measured in the ovarian tissue. Congestion, edema, apoptosis and TRPM2 immunoreactivity were evaluated. Results: There was a significant increase in ovarian weight in the OHSS group compared to the control group. There was a significant increase in congestion, edema, apoptosis and TRPM2 immunoreactivity in the OHSS group. A significant increase in tissue levels of VEGF, TNF­α and MDA was also found in the OHSS group compared to the control group. Conclusion: As a result of our experiment, it was found that increased TRPM2 immunoreactivity on hyperstimulated rat ovary may be the reason or result of edema and congestion. Further studies are needed to discuss our results.

Benign Paroxysmal Positional Vertigo: Comparison of Idiopathic BPPV and BPPV Secondary to Vestibular Neuritis.

The aim of this study was to reveal clinical features of benign paroxysmal positional vertigo (BPPV) through comparing idiopathic BPPV and BPPV secondary to vestibular neuritis (VN). The clinical data of the 189 BPPV patients admitted to our tertiary care hospital including otolaryngological, audiological, vestibular, neurological, and radiological evaluations were reviewed. Patients diagnosed with idiopathic BPPV (n = 145) and BPPV secondary to VN (n = 44) were grouped as I and II, respectively. The clinical data of 2 groups were compared. The findings of the study showed that the patients with secondary BPPV due to VN are much younger, have symptoms of only posterior semicircular canal involvement, and require more treatments compared to patients with idiopathic BPPV. The clinical features of patients with BPPV secondary to VN and idiopathic BPPV differ on several aspects. More extensive studies are needed to investigate the underlying etiology in patients with BPPV encountered after VN.

Symptomatology of COVID-19 from the otorhinolaryngology perspective: a survey of 223 SARS-CoV-2 RNA-positive patients.

PURPOSE: To determine prevalence, severity, duration, and time from onset to diagnosis of general and Otorhinolaryngologic symptoms related to COVID-19 in whole disease spectrum: from mild to critical patients. METHODS: All adult patients with positive SARS-CoV-2 RNA found in nasopharyngeal and oropharyngeal swabs between March 10 and April 21, 2020 were surveyed by the authors for new onset symptoms during disease course. Demographic features, general symptoms, and Otorhinolaryngological symptoms were evaluated and compared by disease severity. RESULTS: Of 223 included patients, 18.4% had mild, 61.4%; moderate, 14.3%; severe, and 5.8%; critical disease. Median age was 51 (range 20-93), 113 (50.7%) were male and 110 (49.3%) were female. The most common general symptoms were fatigue, cough, and fever with respective frequencies of 71.3%, 54.3%, and 50.7%. The most common Otorhinolaryngologic symptoms were taste loss, smell loss, and sore throat with respective frequencies of 34.5%, 31.8%, and 26%. Fatigue, fever, and dyspnea were more common in severe-critical patients compared to mild-moderate patients (p = 0.029, p = 0.016, and p < 0.001, respectively). Only smell loss was more common in mild-moderate group (p = 0.003). Prevalence of other symptoms did not differ between groups. Symptom durations and onset time to diagnosis varied. CONCLUSION: When compared to the previous studies, while general symptoms were less common, Otorhinolaryngologic symptoms were more common in our study population. Considering high infection risks, Otorhinolaryngologists should be aware of COVID-19 patients presenting with Otorhinolaryngologic complaints.

Olfactory Function in Patients With Obstructive Sleep Apnea Using Positive Airway Pressure.

Previous studies reported that positive airway pressure (PAP) treatment may improve olfaction function in patients with obstructive sleep apnea (OSA) through various mechanisms. Olfactory function before and after PAP treatment is understudied regarding patient group at issue. The aim of this study is to investigate the contribution of PAP to olfactory function in patients with OSA. The study was conducted on 26 patients with OSA (10 females and 16 males, mean age 50.1 [9.3] years) who scheduled for PAP treatment. The Connecticut Chemosensory Clinical Research Center odor test was performed before and 4 months after PAP treatment. Patients were grouped (normal, anosmia, mild hyposmia, moderate hyposmia, and severe hyposmia) with respect to olfactory function by measuring odor test parameters, including threshold determination and identification. The odor test average scores of the patients after 4-month PAP treatment compared to pretreatment scores were increased and the difference was statistically significant (P = .002). In the apnea hypopnea index groups, statistically significant difference was found in the threshold and discrimination values regarding before PAP treatment (P = .038, P = .022, respectively). This study revealed that improvement in olfactory thresholds in patients with OSA receiving PAP treatment seems to improve olfactory dysfunction. This provides minimization of OSA consequences, including progressive upper airway inflammation, cognitive impairment, and associated olfactory dysfunction. Resolving the associations between olfactory function and PAP treatment is an important area for future research.

The Effect of Tourniquet Usage and Anesthesia Method on Prognosis in the Treatment of Dorsal Wrist Ganglion Cysts by Open Surgery.

Introduction Ganglion cysts are the most common soft tissue masses seen on the wrist, which often cause pain or cosmetic complaints. The treatment of these masses includes intra-cystic injections or surgery. Recurrence rates are very high in surgical or non-surgical treatment. Inadequate excision for recurrence after surgery is blamed; however, the reasons for the recurrence still remain mysterious. Objectives In this study, the effect of anesthesia selection and tourniquet use on the dorsal wrist ganglion cysts in open surgery was investigated. Materials and methods Patients with dorsal wrist ganglion cysts, who were operated with open surgery between 2015 and 2018 and who had at least six months after the surgery, were examined. The patients were divided into two groups: patients who underwent surgery without tourniquet with local anesthesia and patients operated with tourniquet with general or regional anesthesia. Age, sex, cause of operation, visual analog scale (VAS) scores before and after surgery, limitation of movement, postoperative complications, and recurrence were compared. Results There was no significant difference between the groups in terms of causes of surgery, recurrence rates, preoperative and postoperative limitations of movement, and complications. In terms of age, the group operated with local anesthesia and without tourniquet was significantly larger. There was also no significant difference between the groups in terms of preoperative pain. Postoperative pain was significantly less in the group operated by tourniquet with general-regional anesthesia. Conclusion There is no significant difference in the recurrence and complications between patients operated under local anesthesia without tourniquets and patients operated with tourniquets under general or regional anesthesia during the open excision of the dorsal wrist ganglion cysts. However, it should be kept in mind that postoperative pain does not diminish in later ages, especially in cases of ganglion cysts, and other pathologies may also potentially cause pain in the wrist.

Assessment of facial analysis measurements by golden proportion / Avaliação das medidas de análise facial pela proporção áurea

Abstract Introduction: The face is the most important factor affecting the physical appearance of a person. In facial aesthetics, there is a specific mathematical proportion, which is called golden proportion, used to measure and analyse facial aesthetic qualities in population. Objectives: The aim of this study was to measure the facial soft tissue proportions which would help to constitute a standard for facial beauty and diagnose facial differences and anomalies and to compare these proportions to the golden proportion. Methods: One hundred and thirty-three (133) Turkish patients 18-40 years of age (61 females, 72 males) were involved in the study. Analysis of the photographs was performed by the same physician, and a software programme was used (NIH Image, version 1.62). Facial proportions were measured and differences from the golden proportions were recorded and grouped as normal (1.6-1.699), short (<1.6) and long (>1.699). Results: According to the facial analysis results, the trichion-gnathion/right zygoma-left zygoma was assessed: 33.1% of the patients were in normal facial morphology, 36.8% were in long facial morphology and 30.1% were in short facial morphology, according to this proportion. The trichion-gnathion/right zygoma-left zygoma proportion was significantly higher in males than females (p < 0.001). Statistically significant difference was noted in gender groups, according to the trichion-gnathion/right zygoma-left zygoma and the right lateral canthus-left lateral canthus/right cheilion-left cheilion proportions (p = 0.001, p = 0.028). Conclusion: Facial proportion assessments in relation to the golden proportion showed that a statistically significant difference was observed between gender groups. Long facial morphology was observed more in males (51.4%); normal (41%) and short (39.3%) facial morphology were more common in females. The measurements and proportions for facial balance in our study population showed that the facial width and height proportions deviated from the golden proportion.

Resumo Introdução: A face é o aspecto mais importante da aparência física de uma pessoa. Na estética facial, existe uma proporção matemática específica, chamada de proporção áurea. A proporção áurea é usada para medir e analisar as qualidades estéticas da face na população. Objetivo: Medir as proporções dos tecidos moles faciais que contribuem para o padrão da beleza facial, auxiliar a percepção e o diagnóstico das diferenças e anomalias faciais e comparar essas proporções com a proporção áurea. Método: Foram incluídos no estudo 133 pacientes turcos com 18 a 40 anos (61 mulheres, 72 homens). A análise das fotografias foi realizada pelo mesmo médico e um programa de software foi usado (NIH Image, versão 1.62). As proporções faciais foram medidas e as diferenças das proporções áureas foram registradas e agrupadas como normais (1,6-1,699), curtas (< 1,6) e longas (> 1,699). Resultados: De acordo com os resultados da análise facial, avaliou-se a proporção do tríquion-gnátio/zigoma direito-zigoma esquerdo e 33,1% dos pacientes apresentaram morfologia facial normal, enquanto 36,8% tinham morfologia facial longa e 30,1% morfologia facial curta, segundo essa proporção. A proporção do tríquion-gnátio/zigoma direito-zigoma esquerdo foi significantemente maior em homens do que em mulheres (p < 0,001). Uma diferença estatisticamente significante foi observada entre os sexos, de acordo com a proporção do tríquion-gnátio/zigoma direito-zigoma esquerdo e do canto lateral direito-canto lateral esquerdo/ângulo cantal direito- ângulo cantal esquerdo (p = 0,001, p = 0,028). Conclusão: A avaliação da proporção facial em relação à proporção áurea mostrou que houve diferença estatisticamente significante entre os sexos. A morfologia facial longa foi mais observada no sexo masculino (51,4%), a morfologia facial normal (41%) e a curta (39,3%) foram mais comuns no sexo feminino. As medidas e proporções para o equilíbrio facial em nossa população estudada mostraram que as proporções de largura e altura faciais se desviaram da proporção áurea.

Peritonsillar dexamethasone-bupivacaine vs. bupivacaine infiltration for post-tonsillectomy pain relief in children: a randomized, double-blind, controlled study.

OBJECTIVE: Post-tonsillectomy pain is one of the most frequent morbidities of tonsillectomy surgery. Currently, there is no standard protocol for post-tonsillectomy pain control. In our study, we aimed to compare the effects of perioperative peritonsillar dexamethasone-bupivacaine and bupivacaine-alone infiltration on pain control in pediatric patients. MATERIALS AND METHODS: This prospective, randomized, double-blind, controlled clinical trial was conducted between February 2018 and May 2018 in a single-center tertiary education and research hospital, otorhinolaryngology/head and neck surgery clinic, under general anesthesia, which included 120 pediatric patients between the ages of 2-12 (mean 5.7 ± 1.8), and who were with ASA (American Society of Anesthesiologists) I-II classification. Patients were randomly divided into three groups as 40 participants in each group. Group 1 consisted of patients who were injected with dexamethasone-bupivacaine into their peritonsillar region, group 2 consisted of patients who were injected with bupivacaine only, and group 3 consisted of patients who were injected with saline only as the control group. FLACC (face, legs, activity, cry, consolability) Scale and Wong-Baker FACES® Pain Rating Scale (WBS) were used for early and late period postoperative pain scoring. Patients with pain score ≥ 4 were treated with paracetamol rescue analgesia. Side effects such as nausea, vomiting and bleeding were recorded. Data of all groups were compared statistically and p ≤ 0.05 was considered statistically significant. RESULTS: There was no significant difference between the groups in terms of demographic data, duration of operation and duration of anesthesia. The pain scores of group 1 were significantly lower than those of the control group except for postoperative 45th min, 2nd day and 3rd day. The pain scores of the group 1 were significantly lower at all times except for the postoperative 12th and 24th hour, than those of group 2. The pain scores of the group 2 were lower than the control group only at postoperative 7th day, but no significant difference was found at other times. No statistically significant difference was found between the groups in terms of requirement rates for the first 60 min recovery analgesia (p = 0.686). No statistical difference was found between the groups in terms of side effects. CONCLUSION: In our study, preoperative local dexamethasone-bupivacaine infiltration in pediatric patients was shown to be more effective than bupivacaine-only and serum-only infiltration for early and late post-tonsillectomy pain control.

Findings in Appendectomies with Enterobius vermicularis Infection: Pinworm Is Not A Cause of Appendicitis

Objective: To evaluate the histopathological findings in appendectomy materials with E. vermicularis infection. Methods: Appendectomy materials with E. vermicularis infection of 24 cases were evaluated for the presence of acute inflammation, congestion, hemorrhage, perforation, lymphoid hyperplasia (LH), necrosis, granuloma, fecalith, obliteration, hyalinization, eosinophilic infiltration and mucosal architectural distortion. Results: The frequency of E. vermicularis among 3222 appendectomies that were scanned for the study was 0.74% (24/3222). Female: male ratio was 1:1 and the median age was 12±9.34 years. The most common findings were LH (100%), and congestion (91.7%) Acute inflammation was found in one third (n=8), with phlegmonous inflammation and/or periappendicitis in 4 of them. The patients with periappendicitis were significantly younger (mean age 4 vs. 14.2 years, p=0.008). Feces was present in the lumen in 79.1% of the patients (fecalith in 25%, soft feces in 29.1% and feces mixed with blood and/or suppuration in 25%). In 6 cases (25%), only E. vermicularis was observed in the lumen, with acute appendicitis in 2 of them. Appendiceal lumen was completely obstructed in 12.5% (n=3), while it seemed narrow due to extensive LH in 3 (12.5%) cases. Fibrous obliteration was seen in 4 patients and it was correlated with age and eosinophil count in lamina propria p<0.05. Conclusion: While E. vermicularis infection appears to be an incidental finding in appendectomies rather than being a cause of appendicitis, it probably stimulates LH which may mimic acute appendicitis clinically.

Assessment of facial analysis measurements by golden proportion.

INTRODUCTION: The face is the most important factor affecting the physical appearance of a person. In facial aesthetics, there is a specific mathematical proportion, which is called golden proportion, used to measure and analyse facial aesthetic qualities in population. OBJECTIVES: The aim of this study was to measure the facial soft tissue proportions which would help to constitute a standard for facial beauty and diagnose facial differences and anomalies and to compare these proportions to the golden proportion. METHODS: One hundred and thirty-three (133) Turkish patients 18-40 years of age (61 females, 72 males) were involved in the study. Analysis of the photographs was performed by the same physician, and a software programme was used (NIH Image, version 1.62). Facial proportions were measured and differences from the golden proportions were recorded and grouped as normal (1.6-1.699), short (<1.6) and long (>1.699). RESULTS: According to the facial analysis results, the trichion-gnathion/right zygoma-left zygoma was assessed: 33.1% of the patients were in normal facial morphology, 36.8% were in long facial morphology and 30.1% were in short facial morphology, according to this proportion. The trichion-gnathion/right zygoma-left zygoma proportion was significantly higher in males than females (p<0.001). Statistically significant difference was noted in gender groups, according to the trichion-gnathion/right zygoma-left zygoma and the right lateral canthus-left lateral canthus/right cheilion-left cheilion proportions (p=0.001, p=0.028). CONCLUSION: Facial proportion assessments in relation to the golden proportion showed that a statistically significant difference was observed between gender groups. Long facial morphology was observed more in males (51.4%); normal (41%) and short (39.3%) facial morphology were more common in females. The measurements and proportions for facial balance in our study population showed that the facial width and height proportions deviated from the golden proportion.
