Intracranial Infections Arising From an Odontogenic Infection: A Report of 2 Cases.

Introduction: Intracranial empyema is a rare but serious and life-threatening infection. It is an accumulation of purulent material in the subdural or extradural space leading to development of subdural empyema or intracranial epidural abscess, respectively. The incidence of morbidity and mortality is high because the diagnosis is often unsuspected. Infections of dental origin could be responsible for such condition. Case reports: A 22-year-old female and 30-year-old male patients, both with no significant medical history, presented with subdural empyema and intracranial epidural abscess, respectively, both complicating pan-sinusitis of dental origin. Successful outcomes were achieved with surgical drainage of the lesions, antibiotic therapy, and extraction of affected teeth. Female patient underwent further management for neurological sequelae, while male patient was discharged without neurological complications. Discussion: Intracranial suppuration of odontogenic origin is an uncommon but extremely serious complication. The most common dental origins are caries with periapical involvement and periodontitis. Wisdom tooth extraction is the most common preceding dental procedure for this infection. A multidisciplinary approach is essential for the identification and treatment of suspected oral sources. Antibiotic therapy with surgical approach is the gold standard treatment. Conclusion: This sequel to odontogenic infection is quite rare, but it can be prevented by a good oral hygiene and removal of abscessed teeth.

Prevalence of impacted third molars: a radiographic study among a North African population.

INTRODUCTION: Third molars are the most commonly concerned teeth with the impaction. Impacted third molar (ITM) can be associated to various clinical pathologies Aim: To determine the prevalence of ITM, its pattern and associated affections in Tunisian patients. METHODS: The study reviewed panoramic radiographs of patients consulting the Fattouma Bourguiba University Hospital, Monastir (Tunisia). Orthopantomograms were analyzed to define the prevalence of ITM; its angulation, depth and relation with the anterior border of mandibular ramus. Associated pathologies were also assessed. RESULTS: Seven hundred and thirty patients were included (286 men and 444 women). The age ranged from 19 to 89 years. Half of the patients (50.3%) showed at least one ITM. The total number of ITM was 881 with a statistical difference between arches (respectively 34.3% and 65.7% in the maxilla and in the mandible). The most common number of ITM was two (35.4%). Level C of impaction was observed more frequently in the maxilla and level A in the mandible. The most common angulation was the vertical one for both arches. Seventy six percent of ITM were presented with class II in relation with the anterior border of mandibular ramus. There was no significant difference in the frequency of impaction between gender and sides. The number of ITM associated with pathological conditions was 199 (22.6%). The most frequently observed pathology was the distal caries on the second molars (11.7%) followed by the caries of the third molars (5.2%). CONCLUSION: The prevalence of ITM among Tunisian patients was high.

Gallbladder primary well-differentiated neuroendocrine tumor: A misdiagnosed case.

INTRODUCTION: Gallbladder (GB) Well-Differentiated (WD) Neuroendocrine Tumor (NET) are extremely rare tumors. They represent only about 0.5 % of all Neuroendocrine Neoplasms (NENs). Most GB-NETs are diagnosed after cholecystectomy. They are often misdiagnosed and have good prognosis. CASE PRESENTATION: We share our experience of a 42-year-old woman operated on for symptomatic cholelithiasis. We discover on the anatomopathological piece that it was a Grade 1 NET of the GB. Staging scans and octreotide-scans were normal: there is no distant or nodal metastasis. This tumor was classified as T1bN0M0. After multidisciplinary team discussion, additional treatment is deemed unnecessary. She didn't receive any treatment after the surgery. At one year after the cholecystectomy, she is symptom free and there is no sign of recurrence. DISCUSSION: The diagnosis of GB-WD NET is difficult at the first evaluation. Surgical management for GB cancer has shown increased survival rates, a similar strategy seems reasonable for GB-NETs. Patients with Grade,1 well-differentiated GB-NETS have an excellent prognosis overall. CONCLUSION: Research is required to facilitate earlier diagnosis and to develop management guidelines for GB-NETs.

Rupture of a liver hydatid cyst into the right portal vein leading to right portal vein thrombosis: a case report and literature review.

Hydatid disease (HD) is a worldwide parasitic disease. HD is endemic in many sheep- and cattle-raising areas, with a high prevalence of 5% to 10% in the Mediterranean region. Fistulation of liver hydatid cysts (LHC) in the bile ducts is the most common complication, followed by rupture of cysts in the peritoneal and thoracic cavities. Vascular complications are a rare complication of HD. We describe the case of a 70-year-old woman who was admitted with the chief complaint of pain in the abdominal right upper quadrant for 6 months. Abdominal computed tomography revealed a large LHC in the right liver that had ruptured into the right portal vein branch, with venous thrombosis. Intraoperatively, the right portal vein was opened longitudinally, and the hydatid contents were evacuated. Right hepatectomy was performed to completely excise the LHC. The penetration of a cyst into an adjoining vessel is very rare, and portal vein invasion by HD is extremely rare, with only 10 cases published in the literature, to the best of our knowledge.

Juvenile recurrent parotitis in a 4-year-old patient: a case report.

Juvenile recurrent parotitis (JRP) is a rare disease. It is most commonly occurring between the ages of 3 and 5 years, that classically resolves at adolescence. It is characterized by recurrent non-suppurative parotitis, with several acute inflammatory episodes per year. The parotid´s swelling tends to be unilateral, but it can occur bilaterally, with a more predominant side. The aim of this work was to present a case report that highlights signs and symptoms of this unusual condition and to stress on the value of ultrasonography as an aid to diagnosis.

Epidermoid cyst of the buccal mucosa-An uncommon entity: Case report and literature review.

Epidermoid cyst of the buccal mucosa is rare. Nevertheless, it must be included in the differential diagnosis of swelling in this area. The diagnosis is based on anatomopathological examination. The surgical enucleation is the gold standard of treatment.

Two Lip Carcinomas following Allogeneic Hematopoietic Stem Cell Transplantation: A Case Report and Literature Review.

BACKGROUND: Secondary solid cancers are severe complications in patients who have undergone allogeneic hematopoietic stem cell transplantation (AHSCT) for malignant and nonmalignant lymphohematopoietic diseases. OBJECTIVE: The aim of this work was to report a case of two lip carcinomas following AHSCT and to warn doctors about the importance of regular check-ups of patients who have received HSCT. Observation. A 57-year-old man was referred by the dermatology department for the management of exophytic budding lesions on the lower lip evolving since 5 months. The patient was in complete remission following allogeneic bone marrow transplantation for acute myeloid leukemia since five years. Clinical and histological findings confirmed the diagnosis of a squamous cell carcinoma of the two lesions. CONCLUSION: It is of paramount importance to seek an oral squamous cell carcinoma in the presence of persistent lesions in HSCT recipients.

Jejunal diverticulitis. Review and treatment algorithm.

Diverticulitis is much less common in the jejunum than in colonic diverticula probably because of diverticulum larger size, better intra-luminal flow and relatively sterile jejunal content. Complications of jejunal diverticulitis are acute intestinal obstruction, diverticular bleeding and mainly perforation with mesenteric abscess, localized or generalized peritonitis. The Multi-detector row computed tomography is now the best diagnostic imaging for small bowel diverticulitis as well as its complications. Magnetic resonance enterography is also quite useful but it is still impractical to resort to such an imaging in an abdominal emergency. Non-surgical treatment is usually sufficient for jejunal diverticulitis without peritonitis but it does not prevent recurrence of diverticulitis. Surgery is mandatory in case of generalized peritonitis or voluminous local abscess complicating small bowel diverticulitis. In case of extensive small bowel diverticulosis, resection should be limited to the intestinal loop with complicated diverticulum (local abscess, peritonitis or bleeding) to avoid short bowel syndrome. Poor prognostic factors are advanced age, associated comorbidities, delayed diagnosis and mainly the time interval between perforation and surgery.
