[Morbidity diagnosed in the general medicine public structures in Tunisia].

The study of morbidity in general medicine is very useful in order to adapt training curricula to the reality of medical practice in the first degree. The objective of this work was to describe the morbidity charted in general medicine in Tunisia's Sousse region. It consisted of a prospective and descriptive study involving six basic health centres in Sousse and was conducted over the course of 30 randomly selected days during the year 2000. There were 4022 consultations included in the study which were described according to the SOAP plan. The coding of the charted diagnoses was carried out according to the International Classification of Primary Care (CISP). There were 98% of the consultants who were self-referred and 84% of the consultations corresponded to new cases. The consultants' sex-ratio was 0.5 in favour of females with an average age of 27 years. There were 4,597 diagnoses noted utilising 336 codes from the CISP classification system. The "Respiratory" chapter took the first place on the list (39.6%) followed by the "Circulatory" chapter. The "Top 30" list of the most often charted diagnoses totaled 72% of the consultations among which the three most frequent health problems were pharyngitis (14.4%), acute bronchitis (8.3%) and arterial hypertension (7.4%). This study demonstrates that the practice of general medicine is characterised by instinctive first solutions and versatility. The predominance of cardiovascular and respiratory illnesses illustrates the double burden of morbidity which is faced by Tunisian general medicine practitioners. The "Top 30" list should serve as basis for planning pregraduate and continuing medical training.

[Cervical lymph node involvement in carcinomas of the mobile tongue in Tunisia. Retrospective study of 135 cases].

OBJECTIVE: To report the profile of histologic cervical nodes involvement associated with mobile tongue squamous cell carcinoma. PATIENTS AND METHODS: Our retrospective study concerned patients treated from 1978 to 1998 by cervical neck dissection for mobile tongue carcinoma. RESULTS: A population of 135 patients (90 M/45 F, sex-ratio 2) with a 53.5 mean age (19 to 75) is analyzed. Clinical palpable nodes were present in 68 cases (50%) mainly submental-submaxillar (54). Histologic examination showed a node involvement in 54 cases without (32 cases) or with capsular rupture (22 cases) mainly in the jugulo-carotidian chain (46/54). Among the 67 clinically N0 patients collected after 1990, 22 patients (33%) exhibited an histological involvement vs 32/68 (47%) for the group presenting palpable cervical nodes for the whole period. Histologic node involvement seemed to be linked to the clinical status, node size and TNM stage. CONCLUSION: Cervical lymph node treatment needs to be systematic in mobile tongue carcinoma. The probability of histologic involvement is linked to the loco-regional extent of disease and influences the prognosis. In N0 patients, neck dissection is required because of the frequency of histological involvement, particularly when loss to follow-up may be expected.

[Thyroid papillary microcarcinoma. Salah Azaiz Institute experience].

The incidence of thyroid papillary microcarcinoma appears to be increasing and therapeutic modalities remain controversial. This retrospective study concerns 25 cases, from 1978 to 1999. The circumstances of diagnosis were: a cervicotomy for thyroid nodule (88% of cases), cervical node metastases (8%), and osseous metastases (4%). The sensitivity of ultrasounds was 22.2%, that of scintigraphy was 9.1% and that of extemporaneous histological examination was 18.2%. Multifocality was found in 16% of cases and bilaterality in 16.6%. Treatment modalities were guided by histological examination. Adjunctive radioiodine ablation was used for 20% of the patients. The treatment of the osseous metastases was completed with external irradiation. The average follow up was 4.8 years (4 months to 19 years), with a rate of survival without disease of 100%.

[Thyroid oncocytomas].

OBJECTIVE: Thyroid oncocytomas are rare tumors. They put problems of differential diagnosis enter malignant and benign forms. The modalities of the surgical treatment are controversial, in form as benign as malignant. Their prognosis is also debated. MATERIAL AND METHOD: Our retrospective study concerns 111 thyroid oncocytomas, so 6.5% of thyroid operated in our centre between 1981 and 2001. The sex-ratio of the patients was 0.16 with an average age of 41 years (15 to 72 years). RESULTS: All the fixed nodules, those associated to a recurrential paralysis, to tangible nodes or/and to microcalcifications on the radiography of the neck was malignant. Histological extemporaneous exam was not decisive in 16% of cases, among which 33% showed themselves malignant in the definitive exam, which put in evidence 9 carcinomas (8%). We treated benign oncocytomas by a loboisthmectomy for the isolated nodules, and the subtotal or total thyroidectomy for multinodular glands. For oncocytic carcinomas, we realized a total thyroidectomy with ganglionic taking and histological extemporaneous exam, followed by evidment in case of invasion (2 patients). For the 5 patients having presented a residual fixation, we obtained a white cartography after radioactive iodine administration. For the benign oncocytoma, we did ot notice any recurrences with an average drop of 28 months (2 months to 7 years). For carcinoma, 8 patients on 9 presented an actuarial survival without disease with an average drop of 44 months (18 months to 8 years). CONCLUSION: The diagnosis of malignancy of thyroid oncocytomas can be strongly evoked on however fickle clinical and radiological criteria; it can be eliminated only after definitive anatomo-pathological exam.

[Primary sino-nasal lymphomas. Apropos of 25 cases].

PURPOSE: To report on the epidemiological and therapeutic features of a series of Tunisian patients treated for primitive sinonasal lymphoma. PATIENTS AND METHODS: Our retrospective study concerns patients with histologically proven primitive sinonasal lymphoma diagnosed and treated at our institution from 1975 to 1997. Initial work-up included: clinical plus ENT examination, WBC, ESR, LDH, abdominal ultrasonography, bone marrow biopsy and facial CT-scan taken since 1985. All slides are reviewed and reclassified using the Kiel system. Treatment is based on radiotherapy with or without chemotherapy (mainly with the CHOP protocol). RESULTS: We collected 25 patients (22 males and three females, sex-ratio = 7) with a mean age of 48 years (18 to 78). Mean delay of consultation is 4 months and patients consulted mainly for nasal obstruction (65%), more rarely epistaxis (40%) or rhinorrhea. ENT examination showed a fungating nasal fossa tumor in 20% of cases, predominantly unilateral (80%), associated to cervical nodes in 25% of cases. High-grade lymphomas represented 60% of the cases, and 60% of the patients were stage IE. All stage IEs have been treated by exclusive radiotherapy while more advanced stages received combined chemo- and radiotherapy (eight patients). The five-year actuarial survival rate was 69% for the whole population, with a better prognosis for localized stage and low-grade lymphomas. DISCUSSION: Radiotherapy remains a standard treatment for sinonasal lymphomas, permitting us to cure localized stages. In extended stages (more than IE), combined chemoradiotherapy seems to be a good option, especially in case of bulky tumors as observed for the other nodal and extra-nodal head and neck lymphomas.

[Mucous malignant melanoma of the neck and face. Experience at the Salah Azaiz Institute (Tunis)].

The mucosal melanoma of the head and neck is rare and of late diagnosis. This retrospective study concerns 17 cases brought together in 30 years. Sex-ratio was of 1.1, the average age of 58 years. Tumoral seats were the following ones: nasal cavity and paranasal sinus (n = 10), nasopharyngeal cavity (n = 2), gingival seat (n = 2), palate (n = 1), laryngeal seat (n = 1), middle ear (n = 1). Tumoral extension was classified an follows: stage I: 52.9%, stage II: 17.6%, stage III: 29.4%. Melanomas were achromic in 23.5% of cases. On the therapeutic plan, 47.1% of the patients were treated in a purpose palliative because of the importance of the tumoral extension. Seven patients (41.2%) were treated surgically; three among them received an additional radiotherapy for an insufficient tumoral excision or adenopathy in break capsular. Two patients (11.8%) were treated by exclusive radiotherapy. The rates of survival were 17.6% in 2 years, and 5.9% in 5 years. The average duration of survival was of 18.1 months. The causes of failure were essentially local and metastatic.

[Dermatomyositis and nasopharyngeal carcinoma: 3 cases].

BACKGROUND: Nasopharyngeal carcinoma is a common cancer in Tunisia with an estimated incidence of 1.8/100,000. The tumor shows a characteristic association with paraneoplastic syndromes. CASE REPORTS: We report three cases of histologically proven dermatomyositis associated with nasopharyngeal carcinoma in patients aged 40, 24 and 65 years. In all cases, the course of the paraneoplastic syndrome ran parallel to the nasopharyngeal carcinoma. DISCUSSION: Dermatomyositis is one of the numerous paraneoplastic syndromes associated with nasopharyngeal carcinoma. Systematic examination of the nasopharynx is required in case of dermatomyositis.

[Secondary head and neck osteosarcoma following treatment of undifferentiated nasopharyngeal neoplasms (UCNT)].

Secondary tumours after radio and/or chemotherapy are mainly of hematopoietic (acute non lymphoblastic leukemia, non-Hodgkin lymphoma) or soft tissue lineage previously described most frequently after breast cancer and Hodgkin disease treatment with radio and/or chemotherapy. We report two cases of classical osteosarcoma's observed 9 and 3 years after treatment for UCNT with combined radiotherapy and alkylant-based adjuvant chemotherapy in one case and exclusive loco-regional irradiation in the second case.

[Parotid tuberculosis. Apropos of 2 cases].

The authors report 2 cases of parotid gland tuberculosis treated in the O.R.L. Service of C.H.U. H. Thameur, Tunisia. It's very rare infection even in the countries where the tuberculosis is common (Kuruvilla) (1981) (3). The preoperative diagnosis is difficult with a pleomorphic adenoma, a sarcoma or every parotid tumor. A skin's fistula will help the diagnosis which is confirmed by pathology and bacteriology. The treatment consist in a operative management with specific antibiotics. The prognosis is commonly well.
