Duodenal intraepithelial lymphocytosis during Helicobacter pylori infection is reduced by antibiotic treatment.

AIM: To evaluate clinical, biological and immunological features of patients with increased duodenal intraepithelial lymphocytes (IELs), and its relation to Helicobacter pylori (HP) and coeliac disease (CD). METHODS: We have studied all patients accrued over a 4-year period with increased duodenal IELs. Those patients were recalled for biological and immunological evaluation and a second endoscopy. RESULTS: Twenty-three from a total of 639 patients were identified and 17 of them were included in the study. The median duodenal IEL count was 59 per 100 epithelial cells. Twelve (71%) patients were HP+; eight of them received HP eradication. At the second endoscopy the duodenal IEL count was significantly lower 2 months after HP eradication (73 versus 28), while the IEL count was unchanged in those patients seronegative for HP (n = 5) or those in whom it was not eradicated (n = 4) (55 versus 55). No patient had coeliac antibodies, four expressed HLA-DQ2, lower than in the general population, and the prevalence of CD was 2% (12/639 patients). CONCLUSION: In some cases an increased duodenal IEL count may be due to an inappropriate host response to HP. HP screening and eradication should be considered before recommending a gluten-free diet.

[Experimental study on simultaneous selective reinnervation of the adductors and the abductor muscle for the treatment of the laryngeal paralysis].

OBJECTIVE: The aim of this study is to estimate the value of a new surgical procedure in the treatment of the chronic unilateral laryngeal paralysis. METHODS: The recurrent laryngeal nerve of the left side of the dog was totally cut and served as a model of unilateral laryngeal paralysis at the first step of the research. The adductor and abductor branches of the recurrent laryngeal nerve were then, selected and cut. Afterwards, they were micro-sutured respectively with one branch of ansa cervicalis and phrenic nerve immediately (group 1) and 4 months later (group 2). Six months after this reinnervation, the laryngeal physiologic function of the lateral crico-arytenoid muscle (LCA) and the posterior crico-arytenoid muscle (PCA) have been checked by the methods of electromyography (EMG) and direct laryngoscopy. All the data have been analysed by the statistic methods. RESULTS: Among all the data of EMG, only the wave amplitude of action potential of the LCA muscle of the group 2 was diminished (p < 0.05). Under the direct laryngoscopy, the adductor movement of the left vocal cord of the group 2 was also lightly reduced. But the adductor and abductor movements of the left vocal cord were synchronous with the mouvements of the right vocal cord. CONCLUSION: Though the result of nervous reinnervation of a four month's laryngeal paralysis was not so good by comparison with that of an immediate reinnervation, this surgical procedure can however on the clinical point of view, reach a satisfactory level. The duration maximum of the reinnervation operation after laryngeal paralysis, is, at the present, not clear. It is necessary for us to make further studies.

[Interest of the cervical gland dissection after radiotherapy with or without chemotherapy].

OBJECTIVES: The aim of this study was to evaluate the necessity and morbidity of neck dissection after radiation therapy within organ preservation treatment. PATIENTS AND METHODS: We present a retrospective study of 64 patients, treated initially by radiotherapy with or without chemotherapy for squamous cell carcinoma of head and neck with cervical metastases (> 2 cm), who underwent post-radiation neck dissection between January 1992 and August 2000. Eight (13%) patients were classified T1, nineteen (30%) T2, twenty (31%) T3, eleven (17%) T4 and six (9%) Tx. Eleven patients had N1 neck disease (17%), fifteen patients N2a (24%), eleven patients N2b (17%) and twenty-seven patients N3 (42%). RESULTS: Follow-up ranged from 3 to 86 months with a mean of 39 months. The average length of time between neck dissection and the end of treatment was 60 days. Complications were recorded in 21 patients (33%). Forty-four (68%) of 64 patients had microscopic residual disease. Eight (72%) of 11 patients with N1 neck disease and 17 (63%) of 27 patients with N3 neck disease had pathology. Initial N status was not a predictive factor of microscopic residual disease (p = 0.51). There was no significant relationship between clinical residual adenopathy and microscopic residual disease (p = 0.53). Fourteen patients are still alive without recurrent disease. Eight (57%) of these 14 patients had a positive pathology at the time of neck dissection. The mean follow-up time of these patients is 32.6 months, with a follow up longer than 2 years for half of them (n = 7). CONCLUSION: Neck dissection after radiation was planned for all patients with an initial node > 2 cm in diameter regardless of clinical response in the neck. We confirm that neck dissection appears to be safe after radiotherapy and is necessary because it improves quality of life and prevents fatal evolution with uncontrollable neck disease.

[Spontaneous cervical emphysema: a case report].

Spontaneous cervical subcutaneous emphysema, without any aetiology found in the clinical history, is far less common than subcutaneous cervical emphysema following trauma, surgery, or infectious cervical processes. In this recent case report, the authors describe a young woman who developed a cervical subcutaneous emphysema. No responsible factor had been found. Radiological investigations revealed a pneumomediastinum, which is an uncommon but a serious complication of cervical emphysema. The CT-scan highlighted a rupture of the crico-thyroid membrane, from which the air had followed the fascial planes up to the neck and the mediastinum. The authors describe the treatment and clinical course. They put forward an embryological hypothesis regarding the spontaneous crico-thyroid membrane rupture. A congenital fragility of this area could exist which could explain its breach. The pathogenesis and management of spontaneous cervical emphysema are discussed in the light of diverses articles about this subject. The radiological or surgical explorations which may be used in this aetiological diagnosis and treatment are given.

[A retrospective study of 91 injections of botulinus toxin into the upper sphincter of the oesophagus].

OBJECTIVE: To evaluate the results of botulinus toxin in dysphagia arising in the upper sphincter of the oesophagus. MATERIALS AND METHODS: Since June 1995, 64 patients have had botulinus toxin injected into the upper sphincter of the oesophagus for major swallowing disorders. All cases were treated in the dysphagia service, and underwent clinical assessment, video-swallow screening, and swallowing therapy. The patient cohort included various pathological groups--neurological (vascular accident, head injury, cranial nerve disorders, degenerative diseases), postoperative (surgery for carcinoma of the laryngo-pharynx), and functional, whether purely idiopathic or attributable. RESULTS AND CONCLUSIONS: Global analysis of the results shows that botulinus toxin has good efficacy in relaxing the upper sphincter of the oesophagus; this does not always lead to recovery of normal swallowing, but can bring about improvement by assisting in the therapeutic management of the swallowing problem, and in improving the dietary intake.

[Pneumoparotid: a case report and review of the literature].

This article reports a case of peneumoparotid in a ten-year-old girl. This pathology is caused by insufflation of air into the acini of the parotid gland via Stensen's duct. A review of the literature shows that it has many aetiologies but more frequently it presents as an occupational hazard among glassblowers and wind instrumentalists. It may also occur by auto-insufflation in adolescence who often have psychological problems. The diagnosis is made from the history and imaging. The treatment is aetiologic and symptomatic.

[Portal vein thrombosis associated with a myeloproliferative disorder, prothrombin G20210A mutation, antiphospholipid syndrome, with repermeation during anticoagulant therapy].

Portal vein thrombosis, except in hepatocellular carcinoma and severe cirrhosis, is due to one or several prothrombotic disorders with or without a local precipitating factor. We report a case of a portal and splenic vein thrombosis, without cavernoma and varices which occurred in a 72-year-old man with abdominal pain and weakness. Three prothrombotic states including latent myeloproliferative disorder, antiphospholipid syndrome, and factor II G202101 mutation, were observed. Anticoagulant treatment resulted in complete repermeation of the portal and splenic veins without a hemorrhagic event. This illustrates that several prothrombotic states may occur in a single patient with portal vein thrombosis. Early anticoagulant therapy, in recent portal vein thrombosis, can result in repermeation.

[Loss of visual acuity caused by ethmoidal mucocele cured after endonasal surgery: report of a case].

A posterior and/or ethmoidal mucocele remains a rare occurrence. The condition usually follows a past history of sinonasal surgery. Extension of the lesion may have ophtalmological implications, with the possibility of causing visual impairment. The predilection for a site of origin in the posterior sinuses explains the frequent absence of nasal symptoms, and the usual pattern of discovery by the ophtalmologist. Modern imaging techniques, especially scanning, allows the diagnosis to be made immediately after the first orbital symptoms. By the same token, recent techniques of endoscopic endonasal surgery have radically changed the treatment. Early complete surgical removal holds out hope for remission of the symptoms that led originally to discovery of the mucocele. We report here a case of posterior ethmoidal mucocele causing a visual field defect which reversed completely after endoscopic treatment.

Vallecular acinic cell carcinoma in a 9-year-old girl: report of an unusual case.

An unusual case of acinic cell tumour of the vallecula is presented. Acinic cell carcinoma occurs usually in the major salivary glands. Minor salivary gland location is unusual and vallecular origin exceptional. This peculiar histologic tumour should now be classified as an low grade carcinoma and adequate treatment has to be initiated. The patient, a 9-year-old girl, had undergone a suprahyoid access for total tumor removal with a bilateral neck exploration. Postsurgical radiotherapy has to be done in case with perineural invasion, invaded margins, node invasion or high grade tumor. The clinical and histopathological findings are discussed in the light of the literature.

Postintubation interarytenoid adhesion.

Interarytenoid fibrous adhesion is a poorly recognized complication of intubation and is frequently confused with bilateral vocal cord paralysis. Early diagnosis and treatment is essential for optimal management. Otolaryngologists should constantly remain alert for interarytenoid fibrous scar to establish the diagnosis as early as possible, optimizing the probability of restoring normal breathing and quality of life and avoiding an unnecessary tracheotomy. Surgical laser reduction is appropriate in all cases when other miscellaneous laryngeal injury lesions are eliminated. Direct laryngoscopy with careful examination of the posterior commissure and laryngeal electromyography are the 2 main clinical diagnostic aids contributing to establish the diagnosis.

[Uvular edema. Diagnostic, etiologic and therapeutic management].

Acute oedema of the uvula is relatively rare, and often idiopathic. None the less, possible causes should be excluded, such as allergy, infection, trauma or mechanical. Hereditary angioneurotic oedema should be excluded when there are identical recurrent episodes. Although three of our patients had a recent herpetic viral infection, it does not seem likely that this was the cause. Treatment consists mainly or antihistamines, steroids, antibiotics, or specific treatment for hereditary angioneurotic oedema. The clinician must always bear in mind the potential seriousness or this condition as a cause of obstruction of the upper airway. In the light of four recent cases, the authors discuss the diagnosis, cause and treatment of this particular condition.

[Anatomical study of the thyroid foramen in human larynx: a study of 100 dissections].

The foramen thyroideum was systematically studied on the specimen of larynx of 50 fresh corpses. Among the one hundred dissections performed, the foramen thyroideum was noted only in one specimen (2 foramen). It was symmetrical not only in the position but also in the diameter. In both of these cases, the foramen thyroideum always contains few vessels and nerves. It's possible physiological role and the origin of the contents of the foramen thyroideum are discussed based on the research literature.

[Nasal washing with Physiomer ... 10 years later: 1988-1998].

The authors present the story of Physiomer. It began in 1988 in Goemar's 'Laboratory of the Sea', with an original idea of making a product manufactured from sea water and transforming it into an isotonic solution, while preserving all the elements of natural sea water, specially the trace elements and the alkaline PH. Scientific analysis has shown that the chemical composition of the product is true to the original, and that it has a positive action on cellular growth in respiratory tract mucosa in experimental culture, and it is very well tolerated. Clinical tests using nasal washings have confirmed beneficial action on the nasal and sinus mucosa in medical disease and after surgery. Tests have been carried out on 410 cases, 344 of which were treated with Physiomer, and on 199 cases after surgery on the nose or sinuses. Physiomer nasal washings have proved their value. It now remains for all the potential qualities of sea water to be demonstrated, using other preparations or other combinations.

Laryngomucocele as an unusual late complication of subtotal laryngectomy. Case report.

We report an unusual case of laryngomucocele occurring after subtotal laryngectomy. Laryngoceles generally have a congenital origin in a long-preexisting saccule, and their association with laryngeal carcinoma is well known. Laryngocele is usually favored by the increase of intraglottic pressure caused by the laryngeal carcinoma. However, an iatrogenic secondary laryngomucocele occurring after a surgical procedure is uncommon. We report in detail the physiopathologic conditions leading to the creation of this lesion.

[Comparative intensity-pressure study of patients with a voice prosthesis].

We have studied the qualities of the voice of the laryngectomized patients and theirs possibilities to modify the intensity depending to the pressure. During the measurement, it was necessary to explain to the patient how to use the material and it was an opportunity to help him in the way to product a voice prosthesis. Most of the patients produced a higher intensity with a higher pressure. However, some of them obtained high pressures without producing a voice. These patients modified the use of the prosthesis or could have an oedema for example. In conclusion, these measurements show that there is a relation between intensity and pressure but not absolutely in relation with a better voice quality.

[Otolaryngological manifestations of sarcoidosis. Report of 10 cases and review of the literature].

Sarcoidosis is a systemic chronic granulomatous condition of unknown aetiology. Although the mediastino-pulmonary type is the commonest, the condition may affect the head and neck in a significant number of cases, obliging the practising ENT surgeon to be familiar with the condition. The diagnosis is made by a combination of clinical, biochemical, radiological and histopathological features. We present 10 cases of sarcoidosis with exclusively cervico-facial features which have passed through the department between 1985 and 1996, including a typical nasal case with combined features, and a very rare pharyngeal case. The definitive diagnosis, always with histological confirmation, was sometimes made only after some delay, demonstrating the polymorphic nature of the clinical features, which are rarely pathognomonic. Special investigations, carried out virtually routinely once the diagnosis of ENT sarcoidosis was made, demonstrated only one case of associated pulmonary disease. Treatment was reserved for the symptomatic cases (4 out of 10), and consisted of systemic steroids whose dose and duration was determined by the clinical response.

[A prospective study of ENT complication following surgery of the cervical spine by the anterior approach (preliminary results)].

In order to evaluate complications due to cervical spine surgery using the anterior cervical approach a prospective study was conducted on 125 patients. ENT examination with the fibroscope was employed for all the patients before the procedure. The patients were operated on under general anesthesia and were intubated with an armoured tube, and then were placed in an intensive care unit for 24 hours. Assessment of deglutition and an ENT examination were performed the day after surgery. Before surgery, two cases of vocal cord paralysis were noted. 111 patients (88.8%) presented with subjective disorders: problems such as sore throat, odynophagia, dysphagia, dysphagia with overspill and hoarseness were respectively noted in 55 (44%), 34 (27.2%), 32 (25.6%), 11 (8.8%) and 13 (10.4%) cases. Dyspnoea was found in 2 cases (1.6%). 117 patients (93.6%) presented postoperative anomalies which were found on the posterolateral pharyngeal wall, on the arytenoids and on posterior third of the vocal cords. Inflammatory and/or swollen lesions were slight, moderate, significant or very significant in respectively 22.4%, 22.4%, 15.2% and 1.6% of cases. Very significant circumferential swelling of the pharyngeal wall and of the arytenoids was responsible for two cases of respiratory distress, and the patients required reintubation and return to theatre. Severe pharyngeal lesion correlated with duration of surgery (r = 0.20; p < 0.05), with the number levels of fusion (r = 0.02; p < 0.02) and with the age of the patient (p < 0.02). Six patients presented problems of mobility of the vocal cords: 3 had a right vocal cord paresis which was temporary and 3 had paralysis, also on the right but which persisted. There were no other complications. It is concluded that (i) ENT complications are frequently found in postoperative cervical spine surgery using the anterior cervical approach, some of them being severe. An ENT examination must be performed before the procedure for legal reasons. It is also recommended in the postoperative period in the case of discomfort; (ii) patients need to be placed in an intensive care unit during for the first 24 hours (iii). This study needs to be attended over more patients (iv) comparison with a control group of patients having non cervical surgery and intubated in the same way is needed to differentiate lesions related to surgery or intubation.

Primitive pharyngeal dyskinesia associated with upper airway collapse in an infant.

We report a case of total collapse of the upper pharyngeal airway in a slightly premature baby, resulting in a noisy breathing disorder. Primary immaturity of the central nervous system contributing to pharyngeal muscle hypotonia has been implicated in association with the increase in nasal pressure. The infant experienced complete resolution of symptoms a few weeks after the placement of a nasopharyngeal tube. This case report demonstrates the difficulty in diagnosis and management. The developmental spectrum and exploration are reviewed.
