Explanatory factors for the evolution of children's allergic rhinitis.

INTRODUCTION: Allergic rhinitis (AR) in children is a common condition that is a public health problem. Despite a well-codified treatment, clinical improvement is not the rule. AIM: To identify factors affecting the improvement of allergic rhinitis in children under symptomatic treatment. METHODS: A 12-year retrospective descriptive study that included children aged 3 to 15 years, followed for allergic rhinitis. The search for explanatory factors for improvement under treatment was done using a binary logistic regression model. RESULTS: 52 children were included, with a mean age of 7 years (±3). A familial atopy history was present in 37 patients (71%). The presence of factors aggravating allergy was noted, including antibiotic consumption: 31 patients (60%) and overweight: 15 patients (29%). Associated asthma was noted in 42 patients (81%). The allergenic profile has regained a predominance of dust mite allergy (71%) and a significant frequency of multiallergies (79%). Management included therapeutic education and drug treatment. There was improvement in rhinitis in 27 patients (52%) and improvement in asthma in 26 patients (50%). Overweight and high consumption of antibiotics had a negative impact on the therapeutic outcome. A good therapeutic education had a favorable impact. CONCLUSION: AR is a debilitating condition requiring prolonged therapeutic education and drug treatment. The prescription of antibiotics in children with allergic rhinitis should be sparing and weight monitored.

Reclassification of papillary thyroid microcarcinoma (pMCT) according to the "Porto proposal" criteria.

INTRODUCTION: pMCT is defined as a variant of papillary carcinoma that measures≤1 cm in diameter and which is characterized by an excellent prognosis. Recently, a proposal has been advanced to use the designation of papillary mirotumour (pMT) for pMCTs with no risk factors . AIM: In this study, we aimed to reclassify pMCTs according to the Porto proposal(Pp) criteria. METHODS: We have retrospectively collected cases of pMCT diagnosed in our pathology department over a period of 10years(2012-2022). Clinical and pathological parameters have been retrieved from the patient's medical records and pathological reports. We have evaluated all cases following the criteria of Pp. Cases that fulfilled all the criteria have been reclassified as pMT. We have briefly compared the clinical outcomes in both groups. RESULTS: 29 cases of pMCT was found. Mean age of patients was 46,6 years-old (17-67) with a female predominance (sex ratio=0,45). 23 cases of pMCT were incidentally discovered. The tumor was located in the right thyroid lobe in 15cases. The mean size of the tumor was 5,2mm. Multifocality was observed in 5 cases. A total of 17 cases could be classified as pMT according to the Pp. Only one patient developed pulmonary metastasis and local recurrence; however it was related to the papillary carcinoma firstly diagnosed in his contralateral lobe. Clinical outcome was also good in the group of papillary microcarcinoma (pMC) with no recurrence or distant metastasis. CONCLUSION: According to the Pp,>50% of pMCT could be reclassified as pMT which could reduce the psychological impact and overtreatment. Further studies with large sample size and molecular analysis are however needed in order to definitively validate and generalize the use of Porto proposal.

EpCAM (MOC-31) - immunohistochemical expression in papillary thyroid carcinoma and non invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP).

INTRODUCTION: Ep-CAM, is a cell adhesion glycoprotein located on the basolateral cell membrane surface and in the cytoplasm of most normal epithelial cells. It has also been described to be expressed in several malignancies such as lung, digestive, prostate and renal carcinomas suggesting it has a potential role in carcinogenesis.  In thyroid carcinoma, Ep-CAM expression has rarely been studied especially in papillary thyroid carcinoma. OBJECTIVE: We sought to describe and compare the immunohistochemical expression of MOC31 in papillary thyroid carcinoma and in non invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). METHODS: We have retrospectively collected 33 cases of PTC diagnosed in the pathology department of the Security forces hospital during a period of 13 years (2008-2021). We have microscopically reviewed all cases and reclassified 9 of 33 cases as NIFTP.  An immunohistochemical  automated study have been performed with MOC-31 antibody.  The immunostaining was considered positive when it was membranous and/or cytoplasmic. The intensity of staining was scored as weak (score 1), moderate (score 2), and strong (score 3). We have used an immunoscore for assessing level of expression of MOC31 as follows: 0 for <5% of positive cells, 1 for 5-30%, 2 for 31-50%, 3 for 51-70%.The total score resulted by summing the percentage score with the intensity score; the final score was varying from 0 to 7, considered low between 1-4 and high 5-7. RESULTS: The mean age of patients was 45,2 years-old for PTC cases and 48,1 years-old for NIFTP cases. A net female predominance was found in both groups (male to female ratio of respectively 0,4 and 0,3). MOC31 expression was found in 19 cases of PTC with a percentage of positive cells varying from 5 to 90%. Percentage of positive cells was variable from 5 to 90%. The immunoscore for positive cells was: 0 in 5/24cases, 1 in 4/24cases, 3 in 9/24cases and 4 in 6/24cases. The intensity of staining was assessed score2 (moderate) in 8 cases and score 3 (high) in 7cases (Figure1-2). Final MOC31 staining score was low in 37,5% (9/24) and high in 62.5% (15/24). Patients with advanced pt2-pt3 stages mostly showed high score of MOC31 staining (61,5%).One case was associated with lymph node involvement and was of a high score. 6 cases showed vascular invasion and was of high MOC31 score. MOC31 was expressed in all NIFTP cases with variable proportion of positive cells (5%-80%). The immunoscore for positive cells was: 0 in 1/9cases, 1 in 2/9cases, 2 in 3/9cases, 3 in 1/9cases and 4 in 2/9cases. The intensity of staining was assessed score 1 (weak) in one case, score 2 (moderate) in 6 cases and score 3 (high) in one case (Figure3-4). The final combined score was low in 66,7 (6/9) and high in 33,3% (3/9). CONCLUSION: Our study revealed different immunohistochemical profile of MOC31 in benign and malignant tumors. It has somewhat a diffuse and marked staining in the first group.  The changes of MOC31 location as well as its score of staining in PTC and NIFTP could hence be helpful in the differential diagnosis. Our findings also support the potential prognostic value of this molecule that deserves further investigations.

Petrous metastasis of a lung small cell carcinoma.

Malignant tumors of the temporal bone are rare. They include a wide histological variety. They are mostly primary tumors with an estimated incidence of 0.8-1.0 per 1,000,000 inhabitants per year [1]. Metastases form an uncommon subgroup. The clinical features of these temporal bone metastases are nonspecific and predominantly consist of hearing loss, vertigo, facial palsy, tinnitus, headache, otalgia or otorrhoea [2]. The aim of our publication is to report a rare case of metastasis in the temporal bone as initial manifestation of lung cancer. Our patient was a 44-year-old man who presented for a right mastoid swelling with a grade VI right facial nerve palsy. Imaging and biopsy confirmed the diagnosis of small cell lung carcinoma petrous metastasis. The treatment was palliative. An osteolytic lesion of the temporal bone in an elderly patient may fit with a primary tumor of the temporal bone. It must, also, suggest the diagnosis of metastasis. The malignant tumor most frequently responsible is breast cancer, but lung cancer must also be considered in smoking patients.

Predictive factors for post-total thyroidectomy hypocalcaemia.

INTRODUCTION: Post total thyroidectomy hypocalcemia is a frequent and serious complication of thyroid surgery. Predictive Factors of its risk, justifying the prescription of preventive treatment are to be determined. AIM: To identify the predictive factors of hypocalcemia secondary to total thyroidectomy. METHODS: We report a retrospective study involving 260 patients operated with total thyroidectomy at the ENT department of the military hospital of Tunis over a period of 5 years. A statistical study was carried out to find out predictors of hypocalcemia. RESULTS: Our patients were women in 85% of cases with an average age of 49 years. The incidence of postoperative hypocalcemia was 31.9%. Hypoparathyroidism was definitive in 1.1% of cases. Univariate statistical analysis identified the following factors: presence of cervical swelling at the initial physical exam, gradual onset of mass, thyroid nodule size greater than 4 cm, preoperative calcium level <2.25 mmol/L, one-shot thyroidectomy operating time, histological appearance of thyroiditis and accidental excision of a parathyroid gland. The factors retained in the multivariate study were: gradual onset of mass, nodule size> 4 cm, preoperative calcium level <2.25 mmol/L and histological appearance of thyroiditis. CONCLUSION: Post total thyroidectomy hypocalcemia is linked to intrinsic factors of the thyroid, preoperative calcium level, preoperative and intraoperative parathyroid lesions. Its prevention would include: supplementation of patients with hyperthyroidism or with low preoperative calcium levels, systematic identification of the parathyroid glands and their reimplantation in cases of devascularization.

Lip reconstruction after cancer resection : clinical study of 70 cases.

BACKGROUND: By virtue of their multiple functions, lips are essential organs. Thus, lip cancers represent a distinct entity in head and neck surgery. Their treatment is fundamentally surgical. We aimed, in this study, to define modalities of repairing techniques of lip defects after surgical resection and post-operative complications. METHODS: We conducted a 4 years retrospective descriptive study including 70 adult patients admitted with lip cancers. RESULTS: Suture, local and regional flaps were the performed techniques for repairing defects (respectively n=28, 35 and 7). The most common postoperative complications were wound dehiscence (n=4), and surgical site necrosis (n=2) and infection (9 patients). Functional sequelae were dominated by microstomia (n=26), (food leakage) (n=9) and gingival exposure (n=11). Aesthetic results were good, fair or poor respectively in 54.3%; 32.9% and 12.8% of patients. CONCLUSION: Lip cancers surgery is relatively well-codified. However, it may be difficult to choose the best repairing technique, especially in case of large lip defect considering functional and aesthetic prejudices.

Risk factor of pharyngocutaneous fistula.

INTRODUCTION: Pharyngocutaneous fistula is the most frequent complication of primary and secondary laryngectomy and pharyngolaryngectomy. It has an important impact on the patient, his entourage and the healthcare team. The risk factors for pharyngostoma are multiple and its treatment is not codified. AIM: To identify the various factors that may predispose to this complication and to describe the different therapeutic means to control it. METHODS: This retrospective study examined 68 cases of laryngeal cancer treated by total laryngectomy or pharyngolaryngectomy at Salah Azaїez's head and neck oncologic surgery department between 2015 and 2017. RESULTS: Most of our patients were male (97%) who were major consumer of tobacco and alcohol. The most common stage were T4aN0M0 (34%) and T4aN1M0 (22%). Regarding treatment, we found that 73.5% of patients were operated on by total laryngectomy, 17.7% of patients were operated on by total pharyngolaryngectomy and 8.8% of patients were operated on by square laryngectomy. Pharyngostoma was diagnosed in 20.5% of cases within an average of 15 days. Among the risk factors studied, those that were statistically correlated with the occurrence of CPF in univariate studies were pre-laryngeal infiltration (p = 0.006), postoperative CRP level (p= 0.017), extension to piriform recess (p = 0.009), TNM stage (p=0.039), an associated thyroid surgery (p = 0.020) and pharyngeal closure under tension (p=0.000). In multivariate studies, five of the risk factors identified in the univariate analysis were found. This testifies to their major role as a risk factor for pharyngostoma. These factors were pre-laryngeal infiltration (p=0.001), postoperative CRP level (p=0.000), piriform recess involvement (p=0.004) Associated thyroid surgery (p=0.012) and pharyngeal closure under tension (p = 0.000). CONCLUSION: By identifying predictive factors for pharyngostoma, we can identify patients in which this complication may occur and manage the medical care means to prevent it more efficiently.

Bilateral external laryngocele: a case report.

Laryngocele is a rare benign lesion of the larynx caused by an abnormal dilatation of the laryngeal saccule. We report the case of a 78-year-old man presenting bilateral cervical painless soft mass. Bilateral external laryngocele diagnosis was confirmed by CT scan and the patient underwent a surgical resection.

Synovial cell sarcoma: a rare laryngeal tumor.

Synovial cell sarcoma is a soft tissue tumor that occurs predominately in the lower limbs near the joints. Lesions of the head and neck are extremely rare. The larynx is the least frequent site with only about 20 cases reported in the literature. Treatment of these tumors is controversial and should follow the guidelines for other tumor sites. We report the case of a 37-year-old man with primary laryngeal synovial cell sarcoma, who was surgically managed by a narrow field laryngectomy.

Diagnosis and management of idiopathic facial palsy in children.

Idiopathic or Bell's palsy is an acute peripheral-nerve palsy involving the facial nerve. The disorder is quite infrequent under the age of 10 years. The proposed etiologies of Bell's palsy include ischemic neuropathy and vascular diseases. This case series presents five children with Bell's palsy. The epidemiologic, diagnostic and therapeutic measures were summarized. The evolution regarding especially the facial motricity was detailed. The results about the role of some thrombophilic polymorphisms suggest a probable involvement of factor V haplotype, MTHFR and factor XIII in the etiology of Bell's palsy in five Tunisian children.

Orbital metastasis revealing an undifferenciated Carcinoma of nasopharyngeal type: a case report.

The evolution of the undifferentiated carcinoma of the nasopharynx (NPC) is marked by the occurrence of regional or distant metastasis. We report a rare observation of bilateral orbital metastasis of NPC. Clinical symptoms were ocular proptosis, blurred vision and eye redness. Imaging permitted to precise the extensions of the tumor which was classified T4N1M1 after clinical and paraclinical exams. The treatment consisted of concomitant radiochemotherapy. The evolution didn't revealed recurrence of the disease after 18 months.

A spiritual sleepiness scale: the Friday prayer.

BACKGROUND: Excessive daytime sleepiness (EDS) affects 5% to 20% of the population and is involved in a large number of traffic accidents. EDS is a major symptom in sleep disorders, especially obstructive sleep apnea syndrome (OSA). The daytime sleepiness is evaluated subjectively using scales and questionnaires based on perception. This study is aimed to build a new questionnaire more suited to our lifestyle and then to compare it to the Epworth sleepiness scales (ESS). METHODS: We administered to 91 adult's patients (76 men and 15 women) consulting for sleep disturbance the ESS and a single subjective question tendency to drowsiness during the Friday prayer. Patients were listed in four groups according to their response to the question «During the past month, have you ever doze or fall asleep during the sermon of the Friday prayer? ¼ By G1 never dozes, G2 low chance of falling asleep, G3 average chance of dozing, G4 high chance of falling asleep. RESULTS: Only 63 patients (58 men and 5 women) responded to both questionnaires. Group 1 included 14 patients with a ESS of 5.5 +/- 1.8, Group 2 included 18 patients with a ESS of 7.3 +/- 1.9, Group 3 included 18 patients with a ESS of 11.05 +/- 2 and Group 4 included 13 patients with a ESS of 14.69 +/- 2.3. The Rho correlation coefficient was high (0.86) and shows a strong correlation between the Results of the two questionnaires. CONCLUSION: the answer to the question " During the past month, have you ever doze or fall asleep during the sermon of the Friday prayer? ¼ seems to be an appropriate Sleepiness Scale among Muslim patients.

Acute acoustic trauma: how to manage and how to prevent?

INTRODUCTION: The consequence of an exposure to intense sounds can be a temporary or permanent hearing loss and even with a rapid therapeutic management, severe sensorineural sequelae may persist. METHODS: the authors report a retrospective study about 64 patients followed for an acute acoustic trauma during a period of 8 years (2006 to 2013). For all the cases, a clinical examination associated to a pure-tone audiometry was conducted. Hearing levels were measured at the frequencies 500, 1000, 2000 and 3000 Hertz. Auditory evoked potentials were performed in 17 cases. The therapeutic and evolutive data were detailed and discussed. RESULTS: All our patients were male with a mean age of 34 years. The cause of acoustic trauma was a firing of a gun near the ear in 48 cases, an explosion near the ear in 5 cases and a sudden exposure to loud noises near military planes in 11 cases. Clinical complaints were acute hearing loss with tinnitus. Audiometric exams found a sensorineural hearing loss with a hearing level average of 38 decibels (dB) +/- 14 SD. The therapy consisted of systemic cortisteroids associated in all the cases to peripheral vasodilators.  It was given intravenously during 10 days and then orally with vasodilators during one to 3 months. Hyperbaric oxygenotherapy have been administrated for 25 patients. The follow-up consisted of questioning about symptoms, clinical examination and pure-tone audiometry. A good evolution was noted in 52 cases (81%) and the mean of hearing level after therapy was: 24 dB +/- 12 dB. Despite a prolonged therapy with vaso-active drugs, tinnitus persisted in 36 cases. CONCLUSION: Controlling noise and its harmful effects through technical devices and safety professionals programs are the best way to reduce the frequency and the sensorineural sequelae due to acute acoustic trauma.

Primary Ewing's sarcoma of the sphenoid sinus with orbital and intracranial extension: a case report.

Ewing's sarcoma is a high-grade neuroectodermal primary bone tumor. This is the second primary bone tumor in children afterosteosarcoma and represents 4 to10% of cases. It can occur in all skeletal bones. However, the location at the facial bones is uncommon (1to2%) and extremely rare at the sphenoid sinus. We report the clinical results of a rare case of Ewing's sarcoma of the sphenoid with intraorbitaland intracranial extension.

Management of combat-related facial injuries.

INTRODUCTION: Combat-related facial injuries involve various lesions of the mouth, the eye sockets and the facial bones. The goal of this study is to precise the particularities of these affections and their therapeutic management. METHODS: A retrospective study was performed about 56 cases of combat-related facial injuries over a period of 5 years (2010 - 2014). RESULTS: Our study included 56 male patients with an average age of 29 years (20-37). The trauma occurred during a real security intervention in all the cases. It was isolated in 18 cases and associated to other lesions in 38 cases. Clinical examination revealed facial edema (57%), facial cuts and lacerations (74%), broken teeth (14%), nasal deformation (26%), skin defect (16%) and periorbital ecchymosis (32%). The diagnosis retained after clinical examination and imaging exams were:  fractures of the mandible (34 cases), of the eye sockets (18 cases), of the nasal bones (15 cases), parotid gland injury (5 cases) and facial arterial injuries in (24 cases). The treatment was surgical in all the cases: stabilization of fractured segments (43 cases), suture of facial and vascular lacerations (51 cases), reduction of nasal fractures (15 cases), and reposition of teeth dislocations (35 cases). The evolution was good in 34 cases. The functional sequelae noted were ophthalmic (7 cases), dental abnormal occlusions (11 cases), residual trismus (4 cases) and facial palsy in 2 cases. CONCLUSION: Combat related facial injuries must be diagnosed and treated early to prevent the functional and, sometimes, life-threatening damages dues to those lesions.

Is there a real benefit of hyperbaric oxygenotherapy in the treatment of necrotizing otitis externa?

INTRODUCTION: Necrotizing otitis externa remains a severe and sometimes life-threatening disease in diabetic patient. Many therapeutic approaches have been described but what about the real benefit of hyperbaric oxygenotherapy in the management of this disease? METHODS: The authors reported a retrospective study about 42 patients treated for necrotizing external otitis over a period of 9 years (2006 to 2014). The patients were treated either by only antibiotherapy (23 cases) or with both antibiotherapy and hyperbaric oxygenotherapy (19 cases). The evolution under treatment was appreciated in the two groups through clinical, biological and radiological parameters. RESULTS: The study included 42 diabetic patients with a mean age of 67 years (50 to 84 years). The sex-ratio M/F was 0.82. The diagnosis of necrotizing otitis externa was assessed through clinical and bacteriologic criteria in diabetic patients. A temporal bone CT-scan and a technetium scintigraphy were performed in order to precise the topography of the disease and the level of bone lysis. Antibiotherapy was prescribed intravenously and then orally for a mean period of 8 weeks (5 to 15 weeks). Hyperbaric oxygenotherapy was given for 19 patients (average: 20 sessions). The recovery was affirmed on clinical, biological and radiological features. Otalgia disappeared at the 11th day of treatment without HOT and at the 5th day with HOT. Otorrhea disappeared at the 6th day of treatment by HOT and at the 13th day without HOT. The recovery or the regression of facial palsy occurred in 75% of the cases when HOT was given. The total recovery from the disease was diagnosed in 36 patients (86%). The rate of recovery was 100% in the group treated by HOT and 74% in the group treated by only antibiotics. The recurrence of the disease was noted in 6 patients that haven't benefited from HOT. The end of the oral therapy was guided by the results of the Gallium bone scintigraphy. CONCLUSION: Hyperbaric oxygenotherapy must be associated in the treatment of necrotizing otitis externa. The results of our study suggest a real benefit of this therapy regarding clinical, biological and radiological parameters of this severe affection.

[Brain stem glioma: a rare cause of central vertigo in adults]. / Le gliome du tronc cérébral : cause rare de vertige central de l'adulte.

Unlike children, brainstem gliomas in adults are rare and represent a heterogeneous group of tumors: often low grade tumors having a better prognosis. These tumors are a rare cause of central vertigo in adults. The treatment of diffuse gliomas is based on radiation therapy. We here report the case of a 35-year old female patient with low grade brainstem glioma revealed by balance disorders, in order to highlight the different clinical, paraclinical and radiological aspects of this disease as well as the therapeutic tools and the progressive methods.
