Abstract Introduction Addressing acquired laryngotracheal stenosis presents a complex healthcare dilemma. Results We present a case series of 48 acquired post-intubation laryngotracheal stenosis cases managed within our Department of ENT Surgery at Farhat Hached Tunisia. Diagnosis relied on imaging and endoscopic findings. Among these cases, 28 exhibited tracheal stenosis, with 60% falling into grade 2–3 severity. Management approaches included sole endoscopic dilation for 17 patients, surgical intervention for 19 patients, and T-tube placement for 10 patients. Conclusions The management of laryngotracheal stenosis poses a challenge for ENT surgeons. Prevention is paramount, encompassing various measures such as employing high-volume, high tracheostomy, and extended intubation practices.

Abstract Background The diffuse sclerosing variant of papillary thyroid carcinoma is a rare pathologic entity. It is characterized by a tendency for rapid growth and a higher incidence of cervical lymph node and distant metastases. We report an unusual presentation of diffuse sclerosing variant of papillary thyroid carcinoma presented as a single thyroid mass of a small size. Case presentation We experienced a case of a diffuse sclerosing variant of papillary thyroid carcinoma in a 30-year-old woman. The preoperative findings on the cytology and ultrasound were suggestive of a malignant thyroid nodule. This case was confirmed by surgical excision. The management included surgery, radioiodine ablation, and suppressive levothyroxine therapy. Conclusions We would like to highlight that an early diagnosis associated with an appropriate management leads to a good prognosis.

Abstract Otogenic cerebral sinovenous thrombosis is an intracranial complication secondary to otogenic disease; it is rare but could be a life‐threatening condition. Its management is always challenging. This study aimed to focus on clinical features, on diagnosis of this pathology and to review the most controversial aspect of management of otogenic cerebral sinovenous thrombosis. We reviewed retrospectively 10 inpatients treated with cerebral sinus thrombosis secondary to otitis between 1995 and 2020. Ten inpatients (eight males and two females) with ages ranging from 11 to 77 years were diagnosed with ontogenesis sinus thrombosis. The most commonly reported symptoms were headaches and otalgia. Five patients had mastoiditis, and 7 of the 10 patients had other concurrent complications: cerebellar abscess (three patients) and extradural empyema in two patients, retropharyngeal abscess in one patient, and meningitis in one patient. All patients were treated with broad‐spectrum antibiotherapy, anticoagulation was used to treat nine patients, and surgery was required in nine patients. Nine patients had satisfactory resolution of their symptoms, but one patient had sequel as permanent loss of visual acuity. Because of the inconspicuous clinical presentation, and the probability of a fatal evolution, suspicion is essential for a proper diagnosis and suitable treatment.

* Pleomorphic adenomas (PA) are the most prevalent benign salivary gland neoplasms. They may occur at any age, with a peak incidence between 40 and 60 years of age. They are more commonly observed in females (60%). These tumors can arise in both the major and minor salivary glands. Approximately 80% of these tumors are diagnosed in the parotid gland, whereas 10% arise in the minor salivary glands, mainly affecting the palates, followed by the lips and cheeks. This report describes two cases of unusual lesions that were diagnosed as (PA) in the minor salivary glands in our department via a review of the relevant literature. The first case involved an 83-year-old man who presented with a slow-growing swelling on the right side of the upper lip, and the second case involved a 45-year-old woman who presented with a slow-growing lesion on the palate. The presence of PA was confirmed histopathologically after surgical resection. Although relatively rare, PA is a benign lesion, the diagnosis of which must be known for appropriate therapeutic management.

Abstract Background Distinct virulence factors of H. pylori have been described: the vaculating cytotoxin (vacA), the cytotoxin associated gene (cagA), the induced by contact with epithelium factor Antigen (iceA gene) and the outer membrane protein oipA. In Tunisia, there are no data regarding the pattern of H. pylori genotypes; therefore, this prospective and multicentre study was the first to be done in Tunisia and aimed to investigate the prevalence of the vacA, cagA, iceA and oipA genotypes of H. pylori isolates from Tunisian patients with peptic ulceration, gastric cancer, MALT lymphoma and gastritis. Methods H. pylori was cultured from endoscopic biopsies obtained from 281 Tunisian patients. The vacA alleles, cagA, iceA and oipA genotypes were determined by PCR. Results The vacA s1m1, s1m2 and s2m2 were respectively found in 10.7%, 12.5% and 45.6% of strains. The s2m1 genotype was not detected in our study. The cagA was found in 61.6% of isolates. The iceA1 and the iceA2 genotypes were respectively isolated in 60.2% and in 16% of strains. The oipA genotype was detected in 90.8% of strains. Considering the vacA and iceA genotypes, the presence of multiple H. pylori strains in a single biopsy specimen was found respectively in 31.4% and 23.8%. The comparison between strains isolated from antrum and fundus showed that Tunisian patients were infected with two or more strains of different cagA, vacA, iceA and oipA genotypes and the discordance was respectively in 9.6%, 4.6%, 8.9% and 8.5% of strains. Conclusion Our results showed that in 46% (131 strains among 281), the H. pylori strains were highly virulent in relation of the three or four virulent factors they could carry. These finding were described before in the literature. Tunisian patients were colonized by one or multiple strains of H. pylori in the same time in relation of presence of vacA m1/m2 and iceA1/iceA2 in the same biopsy. The discordance between strains isolated from antrum and fundus was high, and it is in favour of multicolonization.
