Abstract
Granite is an igneous rock that contains natural radioactivity of primordial radionuclides. In Pakistan, granite is distributed in a vast area called the Ambela Granitic Complex (AGC) in North West Frontier Province (NWFP). Granite is a hard rock that exists in different colours and is used to decorate floors, kitchen counter tops, etc. The use of granite in a building as a decor material is a potential source of radiation dose; therefore, natural radioactivity has been measured in 20 granite samples of the AGC with an HPGe (high purity germanium) based gamma ray spectrometer. The average specific activities and their range (given in parentheses) for primordial radionuclides (40)K, (226)Ra and (232)Th were 1218 (899-1927), 659 (46-6120) and 598 (92-3214) Bq kg(-1), respectively. The measured activity concentrations were used for the assessment of hazard indices and radiation dose which were evaluated based on the permissible limits defined for these parameters. The measured specific activities and the derived quantities, hazard indices and radiation dose, have been compared with those given in the literature for these parameters.

Abstract
PURPOSE OF THE STUDY The vascularized fibular graft is a widely used technique for the reconstruction of long bone defects after tumor resection. Complications are not uncommon despite the presence of a good vascular supply. We report our experience with long bone reconstructions in children and adolescents after resection of primary malignant bone tumors. MATERIAL AND METHODS This retrospective analysis included thirteen patients aged 4-17 years (mean age 12 years). Preoperatively, the pathological diagnosis was Ewing tumor (n=7), osteogenic sarcoma (n=5), neuroepithelioma (n=1). All patients except one were given chemotherapy preoperatively and postoperatively and four received adjuvant radiotherapy. Tumor resection created a gap (n=8) or involved resection-arthrodesis (n=5, three knees, one ankle, one elbow). All reconstructions used a vascularized fibular flap with a complementary corticocancellous autograft for seven. RESULTS Complete carcinological resection was achieved in all cases. Mean follow-up was 50 months (range 12-144 months). There were no cases of local recurrence. Three patients presented lung metastasis; two patients died. Eleven of the twelve patients who underwent tumor resection involving the lower limb were able to walk with full weight bearing at 13.9 months (range 841 months), half of them without any supportive device. The MSTS score was 21/30 (range 7-29). Both ends healed for eleven of thirteen grafts. Outcome was good in four cases at 7.7 months (range 6-11), fair in seven (with 1-5 complementary procedures) at 14.8 months (range 10-45) and poor in two (nonunion at last follow-up). Among the fibular grafts which healed, primary healing of the distal end was noted in all cases, but not for the proximal end. Significant transplant hypertrophy was noted in 62% of patients, measured at mean 77.1% (range 25-128%). Complications were: skin necrosis (n=2), nonunion (n=4, three aseptic and one septic), disassembly (n=3 with two transplant fractures), and spontaneous fracture which healed (n=5, all but one treated orthopedically). There were four donor site complications: retraction of the hallux flexor (n=3), regressive paresia of the common fibular nerve (n=1). DISCUSSION The rate of healing in this series was similar to earlier reports. Healing was always achieved for the distal focus but not for the proximal focus which receives its blood supply from a branch of the anterior tibial artery which is not harvested. The defective blood supply can thus hinder bone healing. It is necessary to spare the proximal quarter of the fibula or harvest a bipediculated graft. The rate of graft hypertrophy was also similar, as was the rate of complications. The MSTS score was lower due to the poor results obtained with resection-arthrodesis of the knee joint. Graft fractures and aseptic nonunion are the most common complications but septic complications are more serious and can threaten graft survival. Complications at the donor site are exceptional. CONCLUSION Long bone reconstruction using an autologous vascularized fibular graft is a reliable technique providing satisfactory functional results. Complications can be prevented by making solid fixation and using a corticocancellous graft creating a favorable osteoinducing environment. A massive allograft is another solution providing good immediate mechanical stability.

Abstract
INTRODUCTION Calmette-Guérin bacillus (BCG) is a live attenuated strain used in tuberculosis vaccination. Local and systemic side-effects, although rare, are associated with BCG vaccine. They are common in cases of overdose and with poor vaccination techniques. These complications also occur in some cases of revaccination. PATIENTS AND METHODS This was a retrospective study over a period of 5 years between January 2000 and March 2005. 12 patients presenting complications following revaccination with BCG were observed. Patients were revaccinated with BCG following a negative intradermal reaction test. The following parameters were recorded: age, gender, history, vaccination method, type of complication, treatment and outcome. RESULTS There were 10 men and 2 and women of mean age 21 years (19 to 23 years). Mean time to consultation was 4 weeks. Complications comprised subcutaneous abscess in 8 cases, deep chronic ulcers in 4 cases complicated by humeral osteitis in one case. The dose administered was 0.1 ml in 9 patients and 1 ml in 3 others (i.e. 10 times the recommended dose). Six patients had extensive and progressive ulceration, with one positive culture, the presence of a granuloma with caseum necrosis and one case of humeral osteitis, and specific treatment was given. DISCUSSION Revaccination is no longer recommended by the WHO since efficacy is considered to be low or even nil. Intradermal injection is the reference method for BCG vaccination. Technical errors such as injection of an excessively high dose of the vaccine or subcutaneous administration of the vaccine solution increase the incidence of adverse effects. In our study, three patients erroneously received 1 ml of vaccine and the injection was too deep in 9 cases. There are few reports in the literature concerning the underlying mechanisms of these post-revaccination accidents; two major physiopathological mechanisms, infectious and immunological, are discussed. There is no consensus regarding treatment of these complications. Six of the 12 patients received specific therapy for 6 months.

Abstract
INTRODUCTION The hydatid cyst of Echinococcus granulosus tends to develop in liver. The primary bone hydatidosis is rare. EXEGISIS: The authors report 2 cases of primary hydatidosis of bone in a 57 year old men and 60 year old diabetic women. The symptoms and signs were not specific. The ultrasound investigation: standard radiography and computed tomographic scan, was suggestive of the lesion. The chest radiograph and the abdominal ultrasound were normal. Serological tests for hydatid disease were positive. The two patients have surgical excision and medical treatment: Albendazole administrated for 6 months. Histologic evidence confirmed the diagnosis. The outcome was good for both patients without recurrence after 2 years. CONCLUSION Through these 2 cases and a review of the literature, the authors analyse the epidemiological and clinical aspects of bone hydatidosis and discuss the therapeutic procedures.

Abstract
The beating heart coronary artery bypass technique is becoming more popular in many cardiac units throughout the world. This relativity new technique has prompted surgeons and anaesthetists to review and analysed the routine approach to coronary surgery. In this study we reviewed 26 patients operated off pump technique group I (50 %) and the group II (50 %) operated on pump coronary artery bypass. The patients in the group II were more symptomatic with more heart function, than group I. The postoperative cause of the two groups was similar. This retrospective analysis shows that beating heart technique for coronary surgery can be offered to many patients with good out come and on pump technique can be more safety specially in case of poor myocardial function.

Abstract
The purpose of our study is to determine the causes and the management of anastomotic aneurysms. We report the cases of 25 patients with a mean age of 64 years at the time of initial surgical revascularisation. The mean interval between the first operation and the occurrence of anastomotic aneurysm is 5 years (range 2 months-11 years). The treatment consists on the interposition of a graft in 8 patients, anastomotic angioplasty in 9 patients and the reconstruction of the anastomosis in 8 patients. Hospital mortality was 20%. Late death occurs 3 patients and the long-term morbidity was evaluated at 22%. A recurrence of anastomotic false aneurysm occurred in 4 patients (16%) (Range 7 months-1 year). In conclusion anastomotic false aneurysm is one of the major complications of vascular reconstruction; careful follow-up can detect the rare instances of anastomotic aneurysm and reoperation can be accomplished with a low-rate of adverse outcome.

Abstract
OBJECTIVE The aim of our work was to study cardiac sequelae of penetrating cardiac injuries. MATERIAL AND METHODS It is a retrospective study including nine patients (eight men and one woman with an average age of 26.6 +/- 7.4 years) hospitalised between January 1st, 1988 and December 31, 2002 in cardiovascular surgery department of Tunis Rabta hospital for heart wounds. RESULTS It was stab wounds in all patients. Heart lesions concerned primarily the right ventricle. In admission, two patients had cardiac tamponade and seven were in shock. Beating heart surgery without cardiopulmonary bypass in all patients performed surgical repair and it consisted in simple suture. Functional symptoms were observed in five patients at late outcome. Five patients had heart sequelae. It consisted of conduction abnormalities (right bundle branch block) in five patients. One patient had a small ventricular septal defect. Finally, partial permanent disability rates were less than 10%. CONCLUSION Cardiac sequelae of penetrating cardiac wounds have good prognosis with the exception of a small partial permanent disability rate. Their prevention must be based on the fight against the urban violence and on the good initial management.

Abstract
Cardiac diverticulae are rare, most often affecting the ventricles rather than the atria. We report the case of a diverticulum of the left atrium discovered during routine fetal echocardiography. The diagnosis was confirmed at birth with cardiac echography and an MRI. In view of the patient's age and asymptomatic nature, it was decided to defer surgery and to observe the infant with regular echocardiography. Surgery was eventually performed via a left thoracotomy after the appearance of signs of cardiac compression, and there were no complications in the post-operative period.

Abstract
UNLABELLED Non-typhoidal Salmonella (NTS) infections are a major cause of infantile death in developing countries. OBJECTIVE The aim of this study was to determine the epidemiologic and therapeutic data, as well as the evolution of NTS in Morocco. METHOD This retrospective study was made on 41 patients hospitalized for NTS between 1994 and 2002 in the Casablanca University Hospital Pediatric ward. RESULTS Twenty cases of digestive salmonellosis were diagnosed, 16 cases of septicemia, and 10 cases of meningitis. Ten patients were hospitalized after an outbreak of resistant Salmonella typhimurium in a nursery. Fifty percent of the patients were less than 3 months of age. The three patients between 1 and 3 years of age presented with primary immunodeficiency. Fever, vomiting, and diarrhea were noted in 97% of the cases. The stools were watery in 89% and severe dehydration in 55% of the cases. Salmonella strains were identified in blood in 25 cases, from stools in 10 cases, and from CSF in nine cases. The following Salmonella serotypes were identified: S. typhimurium (53.6%), S. enteritidis (44%), and S. agona (2.4%). Resistance to antibiotics was noted, especially for Salmonella typhimurium (34%) in the nursery outbreak. The evolution was favorable in 80%, but two children with meningitis developed severe neurological sequels, and six hypotrophic infants under 3 years of age died after septicemia.

Abstract
INTRODUCTION Cardiac myxoma is the commune cardiac tumors. Their clinical status depends in the anatomic type. The aim of this study is to evaluate our results and to compare them for literature. PATIENTS AND METHODS From January 1990 to June 2004, 20 patients (8 males and 12 females) with mean age of 49 years underwent surgical treatment of cardiac myxoma. The tumors were in left atrium in 14 cases, in right atrium in 4 cases and biatrial in 2 cases. Surgical treatment consisted in complete resection of the tumor in all cases associated with partial atrial septal resection in 9 cases. RESULTS There is not death in the postoperative outcome. The mean follow up is 50 months. The late mortality rate was 10%. All patients are asymptomatic and the echocardiography control showed no tumor recurrence. CONCLUSION Cardiac myxoma is the communist primary tumor of the heart. Diagnosis is based upon echocardiography. Surgical management has well out come with low morbidity and mortality. Late results are satisfactory but regular screening is recommended although risk of recurrence is low.

Abstract
The association of Tetralogy of Fallot and Ebstein's anomaly is very rare. The authors report a case in a 22 month old baby. As the Ebstein's anomaly was asymptomatic, the surgical indication for repair of the tetralogy of Fallot was the only planned procedure. During surgery, right ventricular dysfunction made it necessary to perform a cavobipulmonary anastomosis. The postoperative course was simple. Very few cases of this type have been found in the literature.

Abstract
Semaphorins are a large family of transmembrane proteins. The gene for SEMA4A encodes a transmembrane protein comprising 760 amino acids. To investigate its association with human retinal degeneration, mutation screening of the SEMA4A gene was carried out on 190 unrelated patients suffering from a variety of eye diseases. We report the first observation of the involvement of SEMA4A gene mutations causing retinitis pigmentosa (RP) and cone rod dystrophy (CRD). We screened the DNA of 135 patients with RP, 25 patients with CRD, and 30 with LCA using SSCP and direct DNA sequencing for mutations in the SEMA4A gene. Two mutations, p.D345H and p.F350C, were observed only in affected patients; they were not observed in any of the normal members or the 100 control subjects. Both mutations identified occur in the conserved semaphorin domain. Multiple sequence alignments using Clustal analysis showed that R713Q is a conserved substitution and D345H is a semi-conserved substitution. We conclude that these mutations are a cause of various retinal degenerations.

Abstract
INTRODUCTION Aldose reductase (ALR2), the enzyme of the polyol pathway, may play an important role in the pathogenesis of diabetic microvascular complications, namely diabetic retinopathy. The study aimed to determine whether the aldose reductase gene is involved in diabetic retinopathy in the Tunisian population. MATERIAL and methods: A case-control study was conducted in 47 type 2 diabetic patients who have diabetic retinopathy and 28 diabetic patients without diabetic retinopathy in spite of diabetes lasting for more than 5 years and over 10 years in 13 cases. We investigated the association between the (CA)n polymorphism located at 2.1 kb upstream of the transcription start site of ALR2 and diabetic retinopathy. The distribution of genotypes and alleles was compared between cases and controls by chi2 test using Epi info software. RESULTS Genotyping of the two groups did not demonstrate any association between the alleles of this marker and diabetic retinopathy in the Tunisian population studied. DISCUSSION An association between one of the alleles (Z - 2) of this microsatellite and diabetic retinopathy was identified in Chinese and Japanese patients with type 2 diabetes. Discordant results were obtained for the different populations studied. The lack of an association between diabetic retinopathy and ALR2 alleles indicates that the ALR2 gene is not a genetic marker of predisposition to diabetic retinopathy for type 2 diabetic patients in the Tunisian population studied.

Abstract
INTRODUCTION Devic optic neuromyelitis is a rare clinical disease that involves severe transverse myelitis and unilateral or bilateral optic neuropathy. Its pathogenesis would be explained by demyelinization triggered by bacterial or viral infections phenomena. According to several author, prognosis would be better in children. CASE REPORT We report a case of optic neuromyelitis in an 8-year-old child with an uneventful history who was admitted because he suffered from flaccid tetraplegia and sudden decline of the visual acuity. The ophthalmologic examination revealed bilateral neuropapillitis. The medullary MRI visualized a spreading myelitis with bifocal arachnoiditis. Search for a precipitating infectious factor showed positive IgM for viral hepatitis A. With corticosteroid treatment the child achieved total recovery of vision and recovered motor and sensorial function of the upper limbs and the trunk. Paraplegia with sphincteral disorders persisted. CONCLUSION This case characterized by the precipitating factor (hepatitis virus A), illustrates this rare syndrome. We present a general review of the pediatric cases reported in the literature.

Abstract
The studies of the HFE mutations: H63D and C282Y in North African populations have revealed the extreme rarity or even the absence of the C282Y mutation. We have examined 1140 chromosomes (570 Tunisian people) for the presence of the two HFE mutations by PCR-RFLP analysis. We have found that the allele frequencies are, respectively, 15.17% (+/-2.1%) for the H63D and 0.09% (+/-0.17%) for the C282Y. These results are consistent with the worldwide spread of the H63D mutation and the north European restriction of the C282Y. This study will be completed by determining whether homozygote trait for H63D and associated risk factors (beta thalassémia) can lead to iron overload in Tunisia.

Abstract
INTRODUCTION Diagnosis of a cardiac hydatid cyst is difficult because of the absence of specific clinical signs. This is a rare disease in adults, but even rarer in children. OBSERVATIONS In a 12 year-old girl, operated on for a pulmonary hyatid cyst 4 years earlier, respiratory distress appeared. This was caused by right heart failure secondary to a chronic hyatid post-embolus pulmonary heart. In a 13 year-old boy exhibiting pulmonary hydatosis (first clinical signs 3 years earlier) echocardiography revealed a multi-compartmented cystic image of the anterior wall of the left atrium, with another similar image in the anterior section of the pulmonary infundibulum. DISCUSSION These observations illustrate the potential gravity of complications of a hydatid cyst, endemic parasitosis in North Africa (metastatic pulmonary echinococcosis and chronic pulmonary heart). Imaging is crucial for the early diagnosis, assessment of the lesions and follow-up after treatment.

Abstract
UNLABELLED The goal of this retrospective study is to review indications and results of cross over bypasses. METHODS AND MATERIAL between January 1990 and December 2000, 60 patients (all males with mean age = 60 years) underwent cross over bypass for unilateral iliac occlusive disease: femoro-femoral in 48%, ilio-femoral in 44% and ilio-popliteal in 8%. RESULTS mortality was 5% while complications occurred in 13.3%. Early limb salvage rate was 92%. During follow-up (mean: 32 months) we noticed 13 late thrombosis. The actuarial patency rate being at 83.5%, 74% and 67% at 1 year, 3 years and 5 years respectively. CONCLUSION cross over bypasses are technically simple with low morbidity and acceptable results. In addition to widely accepted indications (general or local unfavourable conditions to approach abdominal aorta), cross over bypasses may be considered as satisfactory challenge even in young patients with how operative risk.

Abstract
Orbital cellulitis is rare. However the high risk of severe ocular and neurological complications make early diagnosis and adequate therapy essential. The purpose of this retrospective study is to describe 33 cases observed in the pediatric infectious disease department of the Casablanca Children's Hospital in Morocco from 1994 to 2000. Orbital cellulitis was preseptal in 24 patients and retroseptal in 9. Infection occurred in relation with sinusitis in 10 cases, polydermitis in 8, wound infection in 6, ocular infection in 2, and dental abscess in 2. Ages ranged from 40 days to 15 years with a mean age of 5 years. Infants accounted for 25% of cases and always presented preseptal cellulitis. Fever and local edema were noted in all patients. Exophthalmia occurred in six patients and seizures in 2. The 9 cases of retroseptal cellulitis were complicated by empyema in 2 cases, meningitis in 1 case and thrombophlebitis of cavernous sinus with cerebromalacia in 1 case. Bacteriological testing identified micro-organisms in 10 cases, i.e., Staphylococcus aureus in 6 cases, Streptococcus B in 1, Streptococcus pyogenes in 1, Enterobacter Cloacae in land Acinitobacter jejuni in 1 case. Therapy was based on broad-spectrum antibiotics in association with surgery in the patient presenting in intracranial abscess. Ophthalmoplegia-like sequels including blindness, aphasia, and motor deficit occurred in 2 patients. Orbital cellulitis in children are usually preseptal and have a favorable prognosis. However prompt and adequate antibiotherapy is essential due to the risk of retroseptal involvement with inflammatory palpberal edema and possible cerebral extension.

Abstract
The purpose of this study is to determine the diagnosis means, the surgical management and the prognosis of patients with intracavitary cardiac hydatid cyst. We report a series of seven patients. The diagnosis was orientated by coexisting pulmonary locations in all patients. The cyst was located in the right cardiac chambers. Cardiopulmonary bypass with aortic cross clamping and cardioplegia was necessary in all cases. The postoperative course was satisfactory for all patients. There was a recurrence of pulmonary cysts in all patients after a mean duration of 42 months. Medical treatment (Albendazole) was instituted. One late death occurred at 3 years of follow-up due to chronic right heart failure. In conclusion, cardiac hydatid cysts with intracavitary location must be suspected in patients with pulmonary or systemic embolization. Early surgical treatment is necessary and medical treatment must be instituted after surgery.

Abstract
Between 1988 and 2001, five patients with mycotic aneurysm of the abdominal aorta underwent surgery. Extra-anatomical reconstruction with axillo-bifemoral bypass grafting was performed in all patients. The hospital mortality rate was 20%. During the follow-up period two patients presented thrombosis of the axillo-bifemoral bypass, descending aorto-bifemoral bypass was performed in one. Extra-anatomic revascularization is a satisfactory procedure in the treatment of mycotic abdominal aortic aneurysm. The results are acceptable and the prognosis is mainly related to the underlying pathology and the severity of the infection.

Abstract
PURPOSE OF THE STUDY We present a minimally invasive technique for tibial valgus osteotomy using a medial wedge composed of tricalcium phosphate. MATERIAL AND METHODS The bone substitute is composed of slowly resorbable tricalcium phosphate material shaped to the desired form and having mechanical properties allowing stable osteotomy via a short incision and staple fixation. Intraoperative fluoroscopy enables a reliable and reproducible technique. A lateral fixation staple is required because there is a risk the lateral hinge could break. This technique was used for 58 knees in 55 patients (mean age 47 years). According to the Ahlback classification of femorotibial degeneration, there were 43 grade I knees, 12 grade II, and 3 grade III. RESULTS The implant was well tolerated in all cases. Bone healing was achieved in most cases without loss of the osteotomy angle. Complications were: rupture of the lateral hinge in four cases leading to nonunion in one, one low-grade infection. Implant resorption at mid term was significant: among the 22 patients with a follow-up of more than 5 years, the implant was barely visible in 18. DISCUSSION This technique provides an easy way to achieve tibial valgus osteotomy without compromising future intervention. The technique can be considered to be minimally invasive because of the size of the incision, the minimal fixation required, and the bone sparing effect of the bone substitute.

Abstract
We report a case of multifocal tuberculosis with the following features: - skin involvement with multiple gommes disseminated on the left upper limb, the left flank, the right hypocondrium, and the right leg; - nodal involvement including the left supraclavicular, left axillary, right laterotracheal, pre and subcarineal, ceoeliomesenteric, and liver hilus nodes; splenic involvement; right pleural involvement; - spondylodiscitis of T11-T12 and of the head of the right fibula; - peritoneal involvement leading to ascitis; - multi-organ involvement. This 43-year-old woman had not particular history: no diabetes, no renal failure, no long-term corticosteroid treatment, no immunosuppressor treatment, negative HIV-1 and HIV-2 serology. Treatment with anti-tuberculosis agents led to severe drug reactions causing death due to hepatic encephalitis.

Abstract
Several studies of the association between HLA and type 1 diabetes have been carried out revealing differences between ethnic groups. Our study, as part of the studies that should be performed about this association in the rest of the word, aims at elucidating the HLA DRB1, DQB1 polymorphism in Tunisian type 1 diabetes. This study includes 43 unrelated type 1 diabetes patients, and their mean age at onset is less than 15 years. Analysis of the frequency of alleles and haplotypes in these subjects, compared to a reference group (n = 101) led to the following results. 1) The Tunisian insulin-dependent diabetics present similarities as well as differences with other ethnic groups (Caucasians, North Africans). 2) The haplotype DRB1*04 DQ*0302 and DRB1*03 DQB1*0201 is positively associated to type 1 diabetes. 3) The heterozygotic genotype DRB1*04 DQB1*0302 / DRB1*03 DQB1*0201 is strongly associated to type 1 diabetes. 4) The haplotypes DRB1*01501 DQB1*0602 and DRB1*11 DQB1*0301 proved to be protective. In addition, the study of the subtypes DRB1*04 showed that alleles DRB1*0405 predispose to type 1 diabetes, whereas the allele DRB1*0403, which is in linkage disequilibrium with the DQB1*0402 in the Tunisian population, has a protective effect.

Abstract
Susceptibility to type 1 diabetes mellitus is strongly associated with particular HLA class II alleles. However, non HLA genetic factors are likely to be required for the development of disease. The candidate genes include the cytotoxic T lymphocyte associated 4 (CTLA-4) located on chromosome 2q33 and designated (IDDM12), which encodes a cell surface negative signal T molecule providing for activation. We investigated CTLA-4 exon 1 dimorphism in 74 type 1 patients and a control group of 48 healthy subjects from Tunisia using two methods PCR (polymerase chain reaction) allele specific and polymerase chain reaction restriction fragment length polymorphism (PCR RFLP). The CTLA-4/G allele was found on 68.9% in type 1 patients as compared to 51.02% in controls (p = 0.002), mostly in homozygous from 43.24% versus 22.45% (p = 0.0058). This results indicate that CTLA-4/G allele was significantly associated with predisposition to type 1 diabetes in our group from Tunisian population.

Abstract
UNLABELLED The extra anatomical bypasses are those which do not follow the usual arterial pathway. The aim of this study is to define the indication of extra anatomical bypasses and to compare them with other revascularisation procedures. In this paper we report a retrospective study carried between January 1988 and December 1999 involving 80 patients (78 men and 2 women) who underwent extra anatomical bypasses for revascularisation of their lower limbs (83 bypasses). The mean age of the patients was 62 years. The indication for revascularisation was chronic arteritis of the lower limbs in 72 patients (90%), infected aneurysms in 6 cases (7.5%) and acute aortic dissection in 2 cases (2.5%). We performed an axillo-unifemoral bypass in 23 cases, an axillo-bifemoral in 17, a crossover ilio-femoral or femoro-femoral bypass in 41 cases, and 2 transobturator ilio popliteal bypass right and left in 1 case. Hospital mortality rate was 10%. Hospital morbidity was about 65%. Limb salvage was 78%. Sixty patients were regularly followed during a mean follow-up of 31 months. Late mortality was 10%. In the end of our study global limb salvage rate was 74%. IN CONCLUSION extra-anatomical revascularization allows acceptable limb salvage rate along with lower operative risk even in poor state patients.

Abstract
150 patients had mitral valve repair for mitral valve incompetence. There were 57 males and 93 females with a mean age of 22 years. 60% of the patients were in Class II NYHA and 40% in Class III and IV. Type I was present in 18 patients, type II in 98 and type III in 34 cases. Mitral repair included correction of valve prolapse, valvular enlargement with pericardial patch and annuloplasty with semi-rigid ring in 128 cases and PTFE patch along the posterior leaflet in 12 cases. The perioperative mortality rate was 2.6%. All patients had early post-operative echocardiography. According to this, mitral regurgitation was absent or tiny in 135 patients, grade II in 10 cases and grade III in 2 cases. It was moderate or important in twelve patients. In the late post-operative period. All the others patients were reoperated upon for mitral dysfunction in a mean time of 37 months. The reason for reoperation was in the majority of the cases the recurrence of mitral regurgitation related to increase of valvular and sub valvular disease. The late mortality rate is 7%. Out of 126 reviewed survivors on the long run, 71 patients are asymptomatic in class I, 53 patients in class II and 2 patients in class III NYHA. The estimated mitral regurgitation by echography in those patients is absent or trivial in 96 cases. grade II in 29 cases and grade III in one case. Mitral valvuloplasty is the preferred procedure in mitral insufficiency surgical management. It is associated to a low early mortality and morbidity rate. Despite the need for reoperation in about 10% of the cases in the long follow-up, mitral repair offers a good quality of life without anticoagulant treatment.

Abstract
INTRODUCTION Subaortic stenosis is a rare congenital heart disease defined as a left ventricular outflow tract obstruction. We reviewed our surgical experience in this cardiac disease with particularly attention to the different anatomical types of the obstruction. PATIENTS AND METHODS From January 1987 to December 1998, 56 patients with a mean age of 12.4 years underwent surgical treatment of subaortic stenosis in our Institution. The diagnosis included: subaortic membrane in 44 cases, fibromuscular process in seven and tunnel like hypertrophy in five. RESULTS There were two hospital deaths (2/56 = 3.5%) and three patients presented postoperative heart block. The first postoperative echocardiographic control showed a mean fall in left ventricleaorta gradient of 78%. In a mean follow-up of 36 months, there were no deaths. All patients periodically controlled, showed an echocardiographic progression of the gradient and it was not related to the different anatomical types of the obstruction. There were no signs of aortic insufficiency progression. CONCLUSION We can affirm that the surgical treatment of the subaortic obstruction is simple and safe. The medium and long-term progression toward the recurrence is independent to the anatomical type and justify the need of serial echocardiographic control.

In monolayers, interleukin-1beta (IL-1beta) induced COX-2 and NOS II expression in a dose- and time-dependent manner, to produce high prostaglandin E(2) (PGE(2)) and nitrite (NO(2)(-)) levels in an apparently coordinated fashion. COX-2 mRNA was induced earlier (30 min. versus 4 hr) and less markedly (4-fold versus 12-fold at 24 hr) than NOS II, and was poorly affected by the translational inhibitor cycloheximide (CHX). IL-1beta did not stabilize COX-2 mRNA in contrast to CHX. Indomethacin and NS-398 lacked any effect on NO(2)(-) levels whereas L-NMMA and SMT reduced PGE(2) levels at concentration inhibiting NO(2)(-) production from 50 to 90%, even when added at a time allowing a complete expression of both enzymes (8 hr). Basal COX activity was unaffected by NO donors. The SOD mimetic, CuDips inhibited COX-2 activity by more than 75% whereas catalase did not. Inhibition of COX-2 by CuDips was not sensitive to catalase, consistent with a superoxide-mediated effect. In tridimensional culture, IL-1beta inhibited radiolabelled sodium sulphate incorporation while stimulating COX-2 and NOS II activities. Cartilage injury was corrected by L-NMMA or CuDips but not by NSAIDs, consistent with a peroxynitrite-mediated effect. These results show that in chondrocytes: (i) COX2 and NOS II genes are induced sequentially and distinctly by IL-1beta; (ii) COX-1 and COX-2 activity are affected differently by NO-derived species; (iii) peroxynitrite accounts likely for stimulation of COX-2 activity and inhibition of proteoglycan synthesis induced by IL-1beta.

Abstract
To investigate the significance of serological human T-cell lymphotropic virus type 1 (HLTV-1) Gag indeterminate Western blot (WB) patterns in the Caribbean, a 6-year (1993 to 1998) cross-sectional study was conducted with 37,724 blood donors from Guadeloupe (French West Indies), whose sera were routinely screened by enzyme immunoassay (EIA) for the presence of HTLV-1 and -2 antibodies. By using stringent WB criteria, 77 donors (0.20%) were confirmed HTLV-1 seropositive, whereas 150 (0.40%; P < 0.001) were considered HTLV seroindeterminate. Among them, 41.3% (62) exhibited a typical HTLV-1 Gag indeterminate profile (HGIP). Furthermore 76 (50.7%) out of the 150 HTLV-seroindeterminate subjects were sequentially retested, with a mean duration of follow-up of 18.3 months (range, 1 to 70 months). Of these, 55 (72.4%) were still EIA positive and maintained the same WB profile whereas the others became EIA negative. This follow-up survey included 33 persons with an HGIP. Twenty-three of them (69.7%) had profiles that did not evolve over time. Moreover, no case of HTLV-1 seroconversion could be documented over time by studying such sequential samples. HTLV-1 seroprevalence was characterized by an age-dependent curve, a uniform excess in females, a significant relation with hepatitis B core (HBc) antibodies, and a microcluster distribution along the Atlantic coast of Guadeloupe. In contrast, the persons with an HGIP were significantly younger, had a 1:1 sex ratio, did not present any association with HBc antibodies, and were not clustered along the Atlantic façade. These divergent epidemiological features, together with discordant serological screening test results for subjects with HGIP and with the lack of HTLV-1 proviral sequences detected by PCR in their peripheral blood mononuclear cell DNA, strongly suggest that an HGIP does not reflect true HTLV-1 infection. In regard to these data, healthy blood donors with HGIP should be reassured that they are unlikely to be infected with HTLV-1 or HTLV-2.

Abstract
The aim of our study is to determine the ideal operative age of aortic coarctation. 30 patients (20 male and 10 female) have had surgery for coarctation of the aorta between 1990 and 1998. Mean operative age is 4.5 years (range 2 months and 13 years). Crafoord technique was performed in 23 cases, modified Crafoord technique in 3 cases, Waldhausen operation in 3 cases and coarctectomie with insertion of a prosthetic material in one case. A post-coarctectomy syndrome was noted in one case. There were no early deaths. The mean follow-up period is 4.5 years. 8 patients were noted to have late systemic hypertension (26.5%). It is more frequent in patients that have been operated after the age of 5 years (43%). One patient has had a recoarctation (3%). No late death was noted. 4 patients had to undergo a reoperation for cardiac associated anomalies.

Abstract
The aim of our study is to evaluate the effect of nutritional education (applied during young diabetic camps) on the nutrition knowledge acquisition and the effective application of this knowledge by young diabetics in their dietary intake composition. This study included ten volunteers pupils, aged from 12 to 15 years. Each meal provided was quantified before and after consumption to determine during three consecutive days the exact amount of food consumed. Our results showed that the young diabetic could regulate his energetic intake in accordance with his needs. He didn't modify the proposed food when it was normocaloric (2615 +/- 390 Kcal), but he increased his food intake near the recommended needs when the proposed food was hypocaloric (1766 +/- 283 Kcal) and decreased his consumption when the proposed food was hypercaloric (4271 +/- 511 Kcal). Moreover, this study showed a significant negative correlation between the total energy intake and the amount of carbohydrates (r = -0.46, p < 0.01) and proteins (r = -0.70, p < 0.01), while it was positive between the first and lipid intake (r = 0.63, p < 0.01).

Abstract
Glucuronidation of phenols (1-naphthol, 4-methylumbelliferone) and nonsteroidal anti-inflammatory drugs (NSAIDs) such as ketoprofen, naproxen and carprofen was investigated in human colon carcinoma Caco-2 cell clones. Glucuronidation of these substances was highly effective in microsomes of the clones PD-7 and TC-7, but much lower in the PF-11 clone. The activity increased up to a maximum after 21 days of culture. RT-PCR experiments indicated that the PD-7 and TC-7 clones expressed the UDP-glucuronosyltransferase (UGT) isoforms UGT1A6, UGT1A3 and UGT2B7, which could account for the glucuronidation of phenols and carboxylic acids observed. Beta-naphthoflavone stimulated by 2-fold the enzyme activity toward 1-naphthol in PD-7 and TC-7 clones, but not in PF-11 cells. This increase was parallel to that of the UGT1A6 mRNA level. Glucuronidation of ketoprofen was also sensitive to the inducing effect of beta-naphthoflavone. Actinomycin D and cycloheximide did not affect the induction of UGT1A6 by beta-naphthoflavone, but suppressed that of ketoprofen UGT. The UGT1A3 mRNA content was enhanced by beta-naphthoflavone; by contrast, that of UGT2B7 was insensitive to the inducer. In conclusion, several UGT isoforms of both families 1 and 2, which glucuronidate phenols and carboxylic NSAIDs, have been identified in Caco-2 cells. They are differently sensitive to beta-naphthoflavone.
