Comparison of the Outcomes of Early Versus Late Tracheostomy in the Treatment of Critically Ill Patients: A Retrospective Multicenter Measurement Study Done in Two Hospital Centers in Lebanon.

Background  Benefits of early tracheostomy (ET) versus late tracheostomy (LT) while treating critically ill patients have been a matter of big debate in the last few years. Several meta-analyses tried to prove the benefits of ET in decreasing the duration of mechanical ventilation (MV), the length of intensive care unit (ICU) stay, and the mortality rates. However, no clear guidelines are available yet. This study will focus on comparing the outcomes of early tracheostomy versus late one. Methods This is a retrospective study done in two medical and surgical ICUs at "Sacre-Coeur Hospital" and "Rafik Hariri University Hospital" at Beirut, where we reviewed various files of patients who underwent elective tracheostomy for prolonged MV from January 2015 to June 2016. ET and LT were assumed to be procedures performed respectively before and after 10 days of MV. These two groups were subdivided based on the Acute Physiology and Chronic Health Evaluation II (APACHE II) score calculated in the first 24 hours of ICU admission. Data about short- and long-term mortality, the duration of MV, and the length of ICU stay were collected and compared. Results From a total of 45 patients, only 25 patients met the inclusion and exclusion criteria of whom 12 (48%) underwent ET and 13 (52%) patients underwent LT. In patients with APACHE II <25 (6 ET and 6 LT), ET was associated with 50% long-term mortality, 9.6 days mean duration of MV and 23 days mean length of ICU stay compared to 57% (P-value=0.05), 78 days (P-value=0.04) and 79 days (P-value=0.012) of respective parameters in LT groups. In patients with APACHE II >25 (6 ET and 7 LT), ET was associated with 50% long-term mortality, 8.6 days mean duration of MV and 24 days mean length of ICU stay compared to 84%, 105 days, 84 days of respective parameter in LT groups. Conclusions Our results are suggestive of the superiority of ET because it was associated with a reduced duration of MV, a decrease in the length of ICU stay, and, most importantly, a lower long-term mortality rate.

Comparison of Postoperative Pain and Appetite in Pediatric Patients Undergoing Monopolar Tonsillotomy and Cold Steel Tonsillectomy.

OBJECTIVES: Adenotonsillectomy (AT) is amongst the most widely performed pediatric surgeries in the United States (US) and the whole world. AT includes two major surgical techniques: total tonsillectomy (TT) and partial tonsillectomy (PT). Several studies have been conducted to evaluate the difference between TT and PT and assess the comparative effectiveness, benefits, and sequelae between both. In Lebanon, very few studies were done tackling this issue and assessing its sequelae on the pediatric population. METHODS: A prospective study was conducted including pediatric patients aged between 2 and 9 years, who were admitted for partial tonsillectomy (PT) or total tonsillectomy (TT) in 2018. An estimated number of children included were 50: 25 patients underwent PT and 25 patients underwent TT. Patients were sent home on day 1 post-op with a questionnaire that evaluates the following over the first 10 days post-op: pain using the Wong-Baker Faces Pain Rating Scale and the "Parents Postoperative Pain Measure" (PPPM) questionnaire, and appetite using the visual analogue scale (VAS). RESULTS: Patients in the PT group and in the TT group had no demographical differences in terms of age, BMI, exposure to smoking, area of living, and attending a day care center. Comparison between PT and TT revealed a significant difference in both pain and appetite scales. Patients who underwent PT had significantly lower PPPM scores on the 1st, 2nd, 4th, 5th, 6th, and 10th day after surgery compared to the TT patients. Further validation was revealed by the Wong-Baker Faces Pain Rating Scale, showing that the PT surgery group experienced significantly less postoperative pain compared to the TT surgery group. Assessing the appetite using the visual analogue scale favored PT over TT. Comparisons revealed that most PT patients returned to their normal eating habits starting at day 4 while this was applicable in the TT group at day 10. Postoperative pain improved from day 1 to day 10 in both surgical groups. CONCLUSION: In conclusion, the recovery process after the PT surgery causes less postoperative morbidity, thus an earlier return to normal activity compared to the TT. The patients of the latter group are affected by more pain and less appetite over the first 10 days after the surgery.

Intramasseteric Schwanoma mimicking an isolated cheek mass: Case report and review of literature.

INTRODUCTION: Schwannoma is a benign well circumscribed tumor of the nerve sheath and it is mostly localized in the head and neck. Intramasseteric schwannoma represents a very rare entity and a few cases have been described in the literature. PRESENTATION OF CASE: We present a case of an isolated, asymptomatic and slowly progressive right cheek tumor in a middle aged man. Although multiple investigations, including neck scanner and fine needle aspiration, were done, the diagnosis was obscure and difficult before definite surgical resection. Surgery showed an isolated and well-defined tumor inside the masseter muscle which was completely resected. Histopathologic finding confirmed the diagnosis of schwannoma with the characteristic Antoni A and Antoni B cells. DISCUSSION: Among benign tumors of the peripheral nerves, schwannoma is a specific type that originates from Schwann cells. It is typically slowly growing, neoplasm that is displacing neural structures without direct invasion. History, physical examination, fine needle aspiration, and magnetic resonance imaging are used as diagnostic modalities, however definitive diagnosis and identification of the affected nerve are often difficult up to the time of surgery. CONCLUSION: Herby we describe a very rare localization of schwannoma arising from masseter muscle in a 30 year old man who presents with painless neck mass. This rare entity should be considered in the differential diagnosis in any patient presented with cheek mass.

Sinus Floor Augmentation With Ambient Blood and an Absorbable Collagen Sponge: A Prospective Pilot Clinical Study.

PURPOSE: The aim of this study was to clinically, radiologically, and histologically evaluate a sinus augmentation technique using a resorbable collagen sponge to maintain space between the Schneiderian membrane and the residual crestal bone. MATERIALS AND METHODS: Patients with partially edentulous maxillae were clinically and radiographically evaluated for implant placement. A total of 10 consecutive patients with the bone height for implant placement (<4.0 mm) were enrolled in the study. The lateral maxillary wall was surgically exposed and the Schneiderian membrane was carefully elevated. A collagen wound dressing was placed in the antral area between the sinus floor and the raised membrane. The vertical sinus floor height was calculated using cone-beam computed tomography before the surgical procedure (baseline) and at 6 months postoperative. Immediately after the second scan, a core biopsy was removed for histological evaluation. The biopsy site was then further prepared for implant placement in the same location. RESULTS: Biopsies showed mature cancellous bone with a predominantly lamellar structure. Well-vascularized intertrabecular spaces were filled with connective tissue and bone marrow. Analysis of bone height changes showed significant mean (SD) differences before and after procedures in anterior (2.67 ± 0.62 mm and 11.15 ± 1.1 mm), medial (2.98 ± 0.55 mm and 10.96 ± 0.77 mm), and posterior (3.17 ± 0.91 mm and 10.63 ± 0.51 mm) maxillary jaw locations (P = 0.005). CONCLUSION: The collagen sponge provided an effective substrate for osseous regeneration of the sinus floor.

Metachronous, Single Metastasis to the Parotid, from Primary Breast Cancer: A Case Report and Review of the Literature.

Background. The parotid gland is an unusual site for metastatic disease and when metastasis occurs, it commonly originates from head and neck primaries. Spread from distant infraclavicular sites such as the breast, into the parotid, is even more unusual with very few cases reported in the literature. Case Report. We describe the case of a 65-year-old woman presenting for a rapidly enlarging right parotid mass. She had a history of an invasive ductal carcinoma of the right breast and was disease-free in the past 6 years prior to her presentation. She was thereafter diagnosed as having a solitary parotid metastasis from breast origin. A total parotidectomy was done and she was referred for adjuvant radiotherapy. Conclusion. Any parotid metastasis should be investigated, especially in patients with a prior history of cancer where the possibility of metastasis, even if improbable, should be kept in mind. Fine needle aspiration biopsy (FNAB) is the first diagnostic procedure to be done and immunocytochemistry can provide valuable information even if it is not always needed for diagnosis. Superficial parotidectomy when feasible with adjuvant radiotherapy is the preferred approach for solitary metastasis of the parotid. The prognosis, however, remains poor regardless of the treatment modality used.

Measures of the electrically evoked compound action potential threshold and slope in HiRes 90K(TM) users.

OBJECTIVES: To investigate electrically evoked compound action potentials (eCAPs) measured with the neural response imaging (NRI) 'SmartNRI' algorithm. NRI thresholds and slopes were examined according to three aspects: (1) site along the cochlea, (2) development of responses over time, and (3) influence of age/duration of deafness. METHODS: Thirty-four individuals implanted with the Advanced Bionics HiRes 90K(TM) device were included. The eCAP recordings were made from four electrodes along the array at first fitting and at frequent intervals up to at least 2 years. Slope and threshold (tNRI) of the amplitude growth function were measured and a range of explanatory variables were tested for significant effects on these measures using multi-factorial analysis of variance. RESULTS: Electrode position emerged as a significant effect for the tNRI measure, with lowest thresholds at the apical end of the array. Mean slope was greatest for the most apical electrode, but not significantly. Slope was significantly influenced by onset of deafness, with congenital hearing loss associated with steeper slopes than acquired hearing loss. There was also a highly significant effect of duration of device use, with a gradual increase in slope over the 2 years following device activation. DISCUSSION: The observed effects of electrode position are consistent with a model in which eCAP threshold is governed primarily by an effect of distance between electrode and neural interface (which is shorter towards the apex of the cochlea) and in which slope is governed primarily by density of surviving neural elements.

Nasal allergies in the Middle Eastern population: results from the "Allergies in Middle East Survey".

BACKGROUND: Chronic respiratory diseases such as asthma and allergic rhinitis (AR) are a major public health problem in developing countries including those in the Middle East. However, to date, there is a paucity of information related to physician-diagnosed AR in this region. The Allergies in Middle East Survey was undertaken to help clarify and broaden the understanding of physician-diagnosed AR across Egypt, Iran, Lebanon, Saudi Arabia, and the United Arab Emirates. The survey explores the frequency of physician-diagnosed AR, prevalence and types of associated symptoms, the impact on quality of life (QOL), current treatment practices, and therapy expectations. METHODS: In total, 7411 households in five countries (Egypt, Lebanon, Saudi Arabia, Iran and the United Arab Emirates) were screened to identify individuals that were ≥4 years old with a physician diagnosis of AR and either symptoms and/or treatment in the past 12 months. A total of 501 respondents from the five countries completed the survey. Standardized questionnaires were used to make comparisons across the regions; however, the data collection procedures were tailored for each country. The sample was probability based to ensure valid statistical inference to the population. RESULTS: Ten percent of the Middle East population surveyed had a physician diagnosis of AR, with 65% of respondents stating that their allergies were intermittent in nature. An otolaryngologist or allergist diagnosed the majority of the individuals surveyed. Runny nose, nasal and throat itching, postnasal drip, and nasal congestion or stuffed up nose were the most common and bothersome symptoms of AR. The majority of survey participants (58% of the overall survey population) with AR reported that the condition had an impact on their daily private and professional life. Seventy-two percent of adults reported that their AR symptoms limited their work/school activities and 35% reported that their AR interfered with and caused them to miss work or school within the past 12 months. One factor, in addition to the outward AR symptoms, that could have contributed to these function impairments may have been sleep disturbances. Although a secondary symptom to AR, sleep disturbances (difficulty getting to sleep, waking up during the night or lack of a good night's sleep) were shown in this survey to be extremely troubling in ∼15% of AR sufferers. In the past year >90% of patients reported taking a medication of any type for their AR, with nearly a 4:1 ratio of patients taking a prescription medication versus an over-the-counter (OTC) medication in the past 4 weeks. Over 75% of survey respondents reported taking an intranasal corticosteroid (INCS) in the last 4 weeks and the satisfaction rate of INCS medications was similar to that reported for OTC medications. The most common reasons cited for dissatisfaction with INCS medications were inadequate effectiveness, bothersome side effects (e.g., unpleasant taste and retrograde drainage into the pharynx), decreased effectiveness with chronic use, and failure to provide 24-hour relief. CONCLUSION: These data show that AR is common in the Middle East region as elsewhere in the world. Many patients with AR in Middle East region suffer from their symptoms (e.g., runny nose, nasal itching, nasal congestion, postnasal drip, and other symptoms) on all or most days during the times of the year that their allergies are worst. These symptoms have been shown to reduce QOL and performance at work/school to a significant degree. Additionally, the survey data underscore a considerable treatment gap with current therapies for AR and that many AR patients still have not found adequate effectiveness with currently available medications. Thus, through identification of disease impact on the Middle East population and highlighting treatment gaps, clinicians in the Middle East may better understand and treat AR, leading to improvements in overall patient satisfaction and QOL.

Metastatic parotid myoepithelial carcinoma in a 7-year-old boy.

Myoepithelial carcinoma is a rare malignancy of the parotid gland that is usually seen in adults. We report the first case in children of myoepithelial carcinoma of the parotid gland with massive invasion of the facial nerve and metastasis to cervical lymph nodes. Due to its rarity, the treatment and the clinical course of this tumor are not well defined yet. We performed a total parotidectomy, a modified neck dissection, and a postoperative radiotherapy in 7-year-old boy. Sparing of the facial nerve was impossible; it was sacrificed and grafted with a sural nerve. Histopathology confirmed the diagnosis of a parotid gland carcinoma and immunohistochemical markers showed that the tumor cells express cytokeratin, epithelial membrane antigen, cytokeratin 7, smooth muscle actin, P63, CEA, and S100. This pattern of immunostaining is consistent with the diagnosis of myoepithelial carcinoma. On the postoperative tenth month he presented with a pulmonary and lumbar vertebra metastasis.

Inflammatory chronic otitis media and the anterior epitympanic recess.

OBJECTIVE: To demonstrate the important role of the anterior epitympanic recess (AER) in the surgery of noncholesteatomateous chronic inflammatory middle ear disorders. To establish selective criteria as to the indication of surgical intervention on the AER, aiming to create a permanent anterior aeration pathway for the attic. In addition, to point out the mandatory role of preoperative temporal bone computed tomography (CT) demonstrating whether the AER is involved and thus contributing, within the clinical context, to the indication for this surgery and its appropriate approach. STUDY DESIGN: Prospective study on patients with persistent or recurring chronic inflammatory middle ear disease for at least 3 years, after failure of conventional medical or surgical treatments. SETTING: Tertiary referral university centre. PATIENTS: Between November 2002 and July 2003, every patient presenting with clinical findings suggestive of an AER pathology was included in this study. SURGERY: Surgical approach of the AER during a mastoatticotomy and tympanoplasty with excision of the Cog and the tensor tympani fold, preserving the ossicular chain in almost all cases. OUTCOME MEASURES: Absence of postoperative otorrhea, satisfactory otoscopic examination, and improvement in the air-bone gap postoperatively in case the presurgery hearing level was abnormal and not due to an ossicular chain abnormality. RESULTS: Eight patients were included in the study. The preoperative CT scan showed AER opacities in all patients that were either isolated or associated with a diseased meso- or hypotympanum or the mastoid cavity. The measurement of the relevant transverse diameter of the AER is proposed to evaluate preoperatively the distance between the Cog laterally and the facial nerve canal medially to minimize the risk of a perioperative injury. During the operation, we found granulation tissue and adhesions in the AER in all cases A clinical follow-up 3 months after the intervention showed good local control in all patients, absence of otorrhea, and almost complete closure of the air-bone gap at audiometric evaluation. The last clinical follow-up in August 2004, a mean of 18 months after our intervention, did not reveal any relapse of symptoms in any case. CT control could be obtained in five of eight cases, within 13 to 21 months after the intervention, showing a reaerated tympanic cavity and AER. CONCLUSION: The AER plays a major role in sustaining some noncholesteatomateous chronic or recurrent inflammatory middle ear disorders that do not respond to conventional medical treatment. Definitive control of this pathology will be obtained by approaching the AER through an excision of the Cog and the tensor tympani fold, exenterating the inflammatory tissues, and creating a sufficient and permanent anterior atticomesotympanic communication. The indication for such a surgical approach is highly dependent on clinical findings correlated to temporal bone CT. Familiarity with the AER and its critical role should become part of every resident's training program in otology.
