ABSTRACT

BACKGROUND: Hydatidosis is a parasitic endemic disease in Tunisia. The liver and lung are the most common sites of involvement; however, it can develop anywhere in the body. AIM: The aim of the present study was to analyse the epidemiological features of extrapulmonary hydatid cysts and compare our results with those reported in literature. METHODS: A retrospective study of 265 extrapulmonary hydatid cysts collected over the 18-year period from 1990 to 2007 was undertaken. RESULTS: There were 101 male and 164 female patients (sex ratio M/F = 0.61) ranging in age from 2 to 84 years (mean age = 38.7). In our series, hydatid cysts involved mainly the kidney (24.1%), the central nervous system (22.6%), the liver (19.6%) and the spleen (11.3%). The other less frequent sites included the peritoneum (n = 9), heart (n = 9), bone (n = 6), adrenal gland (n = 4), epiploon (n = 4), orbit (n = 4), ovary (n = 3), prostate (n = 2), bladder (n = 2), breast (n = 2), Douglas' cul-de-sac (n = 2), diaphragm (n = 1), testis (n = 1), broad ligament (n = 1), mediastinum (n = 1), nasal cavity (n = 1), soft tissue (n = 1), abdominal wall (n = 1), parotid gland (n = 1), psoas muscle (n = 1), synovia (n = 1), thymus (n = 1) et le pancreas (n = 1). CONCLUSION: In contrast to literature, our results show that hydatid cysts of the kidney and of the central nervous system are more frequent than hepatic location which occupies the 3rd rank.

ABSTRACT

INTRODUCTION: Central nervous system tumours represent 20% of all childhood cancers, and are the second most common group of neoplasms after leukaemias. OBJECTIVE: To describe epidemiological characteristics of central nervous system tumours in a paediatric Tunisian population. PATIENTS AND METHODS: A retrospective study of 492 childhood central nervous system tumours operated between 1990 and 2004 was undertaken. We investigated the age-related location, gender distribution and the histology of all tumours, and adopted the latest WHO classification (2007) in grouping all the tumours. RESULTS: There were 488 primary and 4 secondary tumours; 426 (86.6%) were intracranial and 66 (13.4%) were intraspinal. Of the 426 intracranial tumours, 214 (50.24%) were supratentorial and 212 (49.76%) were infratentorial. The median age at diagnosis was 8 years, with a male:female ratio of 1.14:1. Low-grade tumours (WHO I/II) constituted 67.3% of all lesions and the rest (32.7%) were high-grade tumours (WHO III/IV). The most common tumour found in our series was astrocytoma (38%), followed by medulloblastoma (16.2%), then ependymoma (6.9%), cystic tumours (6.3%) and craniopharyngioma (5.3%). The overall 5-year survival rate was 45% with a mean follow-up period of 36 months. CONCLUSION: In our patient population, the incidence and distribution of central nervous system tumours were similar to those reported in literature. Overall survival rates varied according to tumour location and histopathology.

ABSTRACT

AIM OF STUDY: To assess the value of intraoperative frozen-section diagnosis in thyroid surgery and determine its limitations. METHODS: This retrospective study examined the results of 1534 frozen sections of thyroid specimens analyzed over the 11-year period from 1995 through 2005 and their correlations with the final histological examination. Deferred responses were not taken into account for statistical calculations. RESULTS: In our series, frozen-section diagnosis was concordant with subsequent histopathological examination in 92% of cases, discordant in 3%, and deferred in 5%. The global specificity of frozen section analysis for all histological subtypes was 99.8% and its sensitivity 67%. Its sensitivity for thyroid cancer was lower in follicular (42%) and papillary carcinoma (64%) than medullary (100%), anaplastic (100%), secondary (100%), mixed (100%), and insular carcinomas (86%). CONCLUSION: In our series, as in the literature, most of the discordances between frozen-section and definitive diagnosis were associated with microfollicular lesions, which explain the low sensitivity of 67%. Our results demonstrate the reliability of intraoperative frozen-section analysis in thyroid surgery. Collaboration between pathologists, radiologists, and clinicians should be emphasized.

ABSTRACT

We present the experience of pathological laboratory of la Rabta hospital in extra-pulmonary tuberculosis. We report an epidemiologic retrospective study of 830 cases occurring in our service over a period of 10 years from 1991 to 2000 and diagnosed by histopathological examination. Various epidemiological, clinical, pathological and diagnostic aspects are discussed.
