ABSTRACT
Background: Medical writing is a coded language; its purpose is to convey a scientific message. In pathology, specialty involving the study of cell and tissue, quantitative and qualitative production of medical doctoral theses and their thematic focus has not been studied
The aim of this study was to analyze the pathology theses on the level of form, the background and methodology
Methods: Descriptive retrospective study of medical doctoral theses in the specialty "Pathology", listed in the catalog of theses of the library of the Faculty of Medicine of Tunis and supported between 2000 and 2010. Each thesis has been subject of a direct reading, systematic and thorough
Results: The study involved 189 pathology theses. The average overall productivity per academic pathologist was 5.5 theses. Gastrointestinal pathology was the most studied theme [24.9%]. Tumor pathology was addressed in 74.1% of the theses. The IMRAD structure was respected in 57.7% of theses; by assistant professor than by associate professor and professor [p = 0.005]. The summary was structured in 88.3% of theses, comparably with the grade of the thesis director [p = 0.5] and with the grade of PhD student [p = 0.08]. The transcript of references did not meet the recommendations of Vancouver in 87.8% of theses and irrespective of the rank of director of thesis [p = 0.2]
Conclusion: The pathology theses presented some shortcomings, particularly in the quality of medical writing. To remedy this problem, our faculty should increase efforts to improve the quality of scientific work, in order to have a better view of medical research in Tunisia
ABSTRACT
Gastric heterotopia is a rare congenital lesion, described everywhere in the body, but involves predominantly the digestive tract. Diagnosis is based on histologic examination and requires the presence of gastric mucosa, especially fundic. This diagnosis is usually easy, but sometimes it can be misinterpreted as gastric metapalsia. This latter is an aquired and frequent lesion of the gastrointestinal tract. To determine the relationship between this affection and the other digestive malformations, to describe the clinical characteristics and the evolution of this lesion and to discuss the differential diagnosis particularly the gastric metaplasia. Twelve cases of gastric heterotopia were diagnosed over a 12-year period at Habib Thameur Hospital. Clinical data was obtained and all the slides were reviewed. Nine cases were found in Meckel's diverticulum [75%], one case in intestinal duplication, one case in the esophagus and another in the gallbladder. The mean age of patients at diagnosis was 16 years with a peak of incidence at the first decade of life. Intestinal obstruction and digestive bleeding were the most presenting features. Heterotopic gastric mucosa complicates other congenital anomalies such as common mesentery, vestigial polyp of the liver, appendiceal agenesis and heterotopic pancreas. Differential diagnosis consists in gastric metaplasia was found extensively in a patient with Crohn's disease associated with Meckel's diverticulum. Gastric heterotopia is frequently associated with congenital anomalies especially with Meckel's diverticulum and digestive duplication. Diagnosis relies on histology, mainly on finding heterotopic fundic glands in normal organizational structure. Sometimes, differentiating between gastric heterotopia and gastric metaplasia requires clinical confrontation
ABSTRACT
The salivary gland tumors are rare [less than 3% of all tumors] and poorly known. In fact, they are numerous and histologically difficult to diagnose. This work aims to point at the different histological types of salivary gland tumors, to draw out the principal epidemiological, clinical, radiological and histological characteristics, and to compare our cases to those of the literature. Accordingly, we performed a descriptive type study about 180 cases of salivary gland tumors from the departments of pathology and oto-rhino-laryngology of Habib Thameur hospital during 25 years, extending from April 1979 to December 2004. Benign tumors were predominant [88%], while malignant ones represented 12% of our cases dominated by carcinomas. The sex-ratio was 0.96. Parotid gland location was the most frequent one, and pleomorphic adenoma was the most frequent tumor [62%]. Histological diversity of salivary tumors results in difficulties for differential diagnosis. These problems can be solved by a precise diagnostic approach and sometimes by an immunohistochemistry study

Angiomatoid fibrous histiocytoma is a rare humour affecting young adults. Unlike conventional malignant fibrous histiocytoma, it's extension is only local thus giving a good prognosis. We report the cases of a 9 years-old girl and a 1 6 years-old boy presenting respectively, with an axiliary tumour 5cm of diameter and a paravertebral subcutaneous tumour 1,5cm of diameter. In both cases, the diagnosis was not initially suspected. The treatment consisted in surgical resection
