The effects of adeno/tonsillectomy on cardiopulmonary function based on echocardiography indices in children with primary snoring and mild obstructive sleep apnea.

BACKGROUND: The goal of this study was to evaluate the effects of adenotonsillectomy on heart function based on echocardiography indices in children with primary snoring (PS) and mild obstructive sleep apnea due to adenotonsillar hypertrophy (ATH). METHODS: 55 children (aged 7 to 11 years old) with PS and ATH who were a candidate for adenotonsillectomy from August 2018 to June 2019 evaluated. A history of Upper Respiratory Tract Obstruction was obtained, clinical examination was performed and the cases suspicious for moderate to severe degrees of Obstructive Sleep Apnea Syndrome were excluded. Echocardiography was performed one week before and 3-6 months after surgery. All data were analyzed by SPSS version 19 and P-value<0.05 was considered significant. RESULTS: From 55 enrolled cases, 42 [30 boys (71.5%) and 12 girls (28.5%)] completed the study course. Tricuspid Annular Plane Systolic Excursion (TAPSE), Ejection Fraction (EF), Right Ventricular Peak Systolic Myocardial Velocity (RVSM), Right Ventricular Fractional Area Change (RVFAC) were increased significantly and Isovolumic Contraction Time (IVCT) index was decreased significantly after surgery (P-value<0.05). The difference of indices between the two sexes was not significant after surgery (P-value>0.05). CONCLUSION: Adenotonsillectomy can improve cardiac function indices in patients with PS due to ATH especially in terms of right ventricle (RV) function and reduction in pulmonary artery pressure. So, although "subclinical", it is better to be considered PS not just as annoying noise for roommates before significant clinical cardiac problems happen.

Serum 25-Hydroxy Vitamin D in Chronic Rhinosinusitis with and Without Nasal Polyposis: A Case-Control Study.

INTRODUCTION: Chronic rhinosinusitis (CRS) with and without nasal polyposis is a chronic inflammatory disease of the sinuses and nasal mucosa. Recent evidence has indicated a relationship between serum 25-hydroxyl vitamin D (OH-VitD) deficiency and CRS. Regarding this, the present study aimed to compare the serum level of 25-OH-VitD in CRS patients with and without nasal polyposis and control groups. MATERIALS AND METHODS: This study was conducted on 117 adult subjects in three groups of CRS with nasal polyposis (CRSwNP; n=32), CRS without nasal polyposis (CRSsNP; n=35), and healthy controls (n=50). The mean level of serum 25-OH-VitD in the three groups was measured by means of enzyme- linked immunosorbent assay. The data were analyzed using SPSS software (version 18). RESULTS: Mean serum levels of 25-OH-VitD in CRSwNP, CRSsNP, and control groups were 12.52, 15.54, and 22.04 ng/ml, respectively. There was a significant difference between the case and control groups in terms of 25-OH-VitD level (P=0.0001). However, no significant difference was observed between the CRSwNP and CRSsNP groups in this regard (P=0.464). The women had a VitD deficiency odds ratio (OR) of 2.47, compared with men (OR=2.47, 95% CI=1.04-5.86). The OR of VitD deficiency with aging was obtained as 0.957 (95% CI=0.925-0.989). In this regard, older patients had a lower probability of VitD deficiency, compared to younger patients. CONCLUSION: As the findings indicated, serum 25-OH-VitD was significantly lower in CRS patients, compared with that in the non-CRS subjects.

Ultrasonography findings in nasal bone fracture; 6-month follow-up: can we estimate time of trauma?

Differentiation of a recent nasal bone fracture from an old one may become of utmost importance, especially in medico-legal issues. The aim of this study was to demonstrate the value of high-resolution ultrasonography (HRUS) in determining the time of nasal bone fracture. A longitudinal, descriptive-analytic study was done on 45 patients with a clinical manifestation of acute unilateral nasal bone fracture. After a thorough rhinologic physical examination, HRUS was performed by an expert consultant who was blinded to the clinical data of the patients. All patients were followed-up for 6 months: in the first 5 days, 3rd, 6th, 12th and 24th weeks after the trauma. In each session, the ultrasonographic findings were recorded. Thirty-six cases (mean age, 27 years) completed the study course successfully. On HRUS, subperiosteal hematoma, with a mean thickness of 1.14 mm (0.79-1.31 mm) was highly sensitive (100 %) for the diagnosis of nasal bone fracture during the first few days after the trauma, but it was present in 13 cases in the 6th week, with a mean thickness of 0.71 mm (0.62-0.80 mm), and disappeared in all patients in the 24th week, with a mean thickness of 0.47 mm (almost equal to the non-traumatic side). According to the changes of subperiosteal reaction on the traumatic side and by means of generalized linear model and generalized estimating equations, we proposed an equation to estimate the time of nasal bone trauma. In conclusion, HRUS is a reliable diagnostic tool for estimating the time of nasal bone fracture.

Ultrasonographic evaluation of long-term results of nasal tip defatting in rhinoplasty cases.

OBJECTIVES/HYPOTHESIS: Nasal skin thickness has an important role in aesthetic results of rhinoplasty. The aim of this study was to evaluate the long-term results of tip and supratip skin defatting technique in rhinoplasty subjects using ultrasonography. STUDY DESIGN: Prospective, randomized, case-control study. METHODS: Among 111 rhinoplasty cases referred to a university hospital between February 2010 and September 2011, after physical examination and measuring the nasal tip and supratip skin thickness by ultrasonography, a total of 55 patients with thick and moderate skin were randomly allocated for rhinoplasty using one of the following methods: rhinoplasty with (case group) and without (control group) defatting tip and supratip skin. Ultrasonographic evaluation of the skins was repeated 1 and 12 months after surgery, and the data were analyzed by Wilcoxon and repeated measure tests using SPSS 17 software. RESULTS: Twenty-eight of 55 candidates (10 men, 45 women; mean age, 25.1 ± 7.6 years) underwent skin defatting during rhinoplasty; the other 27 patients did not undergo this procedure. Forty-four patients completed the study. Thickness of tip and supratip skin was not statistically different before surgery and during follow-up evaluations in defatting and nondefatting technique groups (P = .7). CONCLUSIONS: Defatting techniques have no effect on reducing tip and supratip skin thickness after rhinoplasty in moderate to thick skins.

Hearing statement in multiple sclerosis: a case control study using auditory brainstem responses and otoacoustic emissions.

Multiple Sclerosis (MS) is a demyelinating disorder of Central Nervous System. It involves 8th cranial nerve and its central nuclei and is an uncommon cause of the sensorineural hearing loss. For determining the prevalence of hearing loss (HL) especially retrocochlear type in MS, a cross-sectional study was designed using Pure-Tone Audiometry (PTA), Otoacustic Emissions (OAEs), Auditory Brainstem Responses (ABRs) compared with the control group. Data were analyzed by Qui2 & Fischer exact test in SPSS 17 software. Among 60 patients (44 women & 16 men) and 38 controls (27 women & 11 men) with a mean age of 29.9±9.8 and 31.4± 8.3 years, 12.5% of case ears and 3.9% of the control ears had abnormal PTA (P= 0.043). Frequency of abnormal high frequency-PTA and two modalities of OAEs were not significantly different between case and control ears. The means of overall correlation were 75.9±23.8 in cases and 70.0±27.2 in controls (P= 0.111). 20% of case ears, and 9.2% of the control ears had abnormal ABRs (P= 0.044). The absolute latencies of waves I, II & V had not significant difference, but 10% and 11.7% of case ears and 1.3% & none of the control ears had increased inter peak latencies of I-III, and III-V respectively (P<0.05). 6.7% of case ears and 2.6% of control ears had retrocochlear abnormality (P=0.181). In conclusion, HL is more common in MS patients, especially when determined by using PTA and ABR.

Investigating Helicobacter pylori in nasal polyposis using polymerase chain reaction, urease test and culture.

The aim of this study was to identify the presence of Helicobacter pylori in nasal polyp specimens of patients with nasal polyposis. A cross-sectional study with control group was performed on fresh tissue samples from 25 patients with nasal polyps, and 25 persons with concha bollusa (control group). Patients with symptoms of gastroesophageal reflux (GERD) were not enrolled. Samples were studied by three methods: polymerase chain reaction (PCR), culture, and urease test. All the diagnostic tests were negative for H. pylori in both the case and control groups. In conclusion, there was no association between H. pylori and nasal polyposis in patients without GERD signs or symptoms in our study, and further studies are needed to assess other potential factors that may influence the development of nasal polyposis.

Bipolar radiofrequency tonsillotomy compared with traditional cold dissection tonsillectomy in adults with recurrent tonsillitis.

OBJECTIVE: To compare short- and long-term results of radiofrequency tonsillotomy and traditional cold dissection tonsillectomy in adult patients with recurrent tonsillitis. STUDY DESIGN: A randomized clinical trial. SETTING: A tertiary referral university hospital. SUBJECTS AND METHODS: Of 62 adults with recurrent tonsillitis, 24 patients were treated with cold dissection tonsillectomy, while radiofrequency tonsillotomy (RF) by use of radiofrequency induced thermotherapy probes was performed in the remaining 38 patients. Duration of surgery, amount of intraoperative bleeding, recovery time, postsurgical pain (measured by use of visual analogue scale on days 1, 3, 5, and 10 after surgery), dysphagia, weight loss, and time of return to normal diet and activity were measured. All the patients were followed for 12 to 24 months for recurrence of tonsillitis episodes. RESULTS: Comparing the radiofrequency tonsillotomy group to the cold dissection tonsillectomy group, mean duration of surgery was 16.89 versus 45.04 minutes, recovery time was 14.32 minutes versus 17.08 minutes, and amount of intraoperative bleeding was 15 to 20 cc versus 250 to 300 cc, respectively (P < 0.005). There was no difference between the two groups in the recurrence of tonsillitis episodes after 24 months. CONCLUSION: Tonsillotomy with radiofrequency is a simple, rapid, and effective method in adult patients with recurrent tonsillitis.
