RESUMO

OBJECTIVES: The Hamilton Depression Rating Scale (HDRS) is one of the most frequently used depression assessment scales. In Tunisia, psychiatrists commonly use this scale in a Tunisian dialect. However, to the best of our knowledge, this scale has never been validated in Tunisia. This study aims to investigate the reliability and the validity of the HDRS among Tunisian patients who have been hospitalised for a suicide attempt. A secondary objective is to describe the sociodemographic characteristics of the study population. STUDY DESIGN: This is a cross-sectional study performed in the emergency department. METHODS: Patients who were hospitalised for a suicide attempt were eligible for inclusion in this study. The Tunisian version of the HDRS was developed using a forward-backward translation procedure. Psychometric properties of the Tunisian version of the HDRS were tested, including (i) construct validity with a confirmatory one-factor analysis; (ii) internal validity with Pearson correlations and Cronbach alpha coefficients; and (iii) external validity by correlations with the Patient Health Quality-9 (PHQ-9) scale. We used the Receiver-Operating Characteristic (ROC) curve to analyse the correlation between the total HDRS score and the presence of depression according to the PHQ-9. RESULTS: In total, 101 participants were enrolled in this study. The principal component analysis (PCA) type factor analysis with varimax rotation found a high-grade correlation between HDRS individual items and the total score. The total variance, explained by five factors, was 64.4%. Cronbach's standardised alpha coefficient was 0.86 for the overall scale. Correlations between the total HDRS score and the PHQ-9 score, and its various items, were significant. The ROC curve analysis showed good sensitivity (80.8%) and specificity (91.1%). CONCLUSION: The Tunisian version of the HDRS is an acceptable instrument to screen depression in individuals who have attempted suicide.

RESUMO

OBJECTIVE: To explore unusual association between Turner Syndrome (TS) and Hypopituitarism in a Tunisian cohort. METHODS: We reported 6 patients with TS associated to Hypopituitarism, including three familial cases except the fourth sister who showed only a TS phenotype. Biochemical analysis, resonance magnetic imaging and cytogenetic analyses were performed. RESULTS: The average age of our patients was 17.2 years (11-31 years). They were all referred for short stature and pubertal delay, except for the fourth sister who presented spontaneous puberty with the integrity of the pituitary axis and the presence of an X ring chromosome. Karyotype analysis showed monosomy in 3 cases and a mosaic TS in the 3 remaining cases, including one patient with abnormal X chromosome structure. Somatotropic and corticotropic deficiencies were confirmed in 2 sporadic cases while the gonadotropic and thyrotropic axes were spared. In contrast; familial cases were consistently affected by the integrity of the corticotropic axis. MRI showed pituitary hypoplasia in all familial cases and pituitary stalk interruption syndrome in only one sporadic case. No correlation was found between the chromosome formula and the anterior pituitary involvement. CONCLUSION: Co-segregation of congenital Hypopituitarism with pituitary hypoplasia and X chromosome aberrations could imply a molecular anomaly of transcription factors responsible for the differentiation and development of pituitary cells such as PROP1, POUF1, Hesx1, Lhx3, Lhx4. The etiopathogenic link between X chromosome abnormalities and the occurrence of Hypopituitarism remains unclear; however, the progress of molecular biology may clarify the interrelation between transcription factors and sex chromosome segregation abnormalities.

RESUMO

The role of androgens in cardiovascular disease is still controversial in men. In this study, we investigated metabolic disorders in Tunisian hypogonadal men compared with healthy controls. Forty hypogonadal men and 80 control subjects were enrolled. Patients with a history of pre-existing panhypopituitarism, thyroid dysfunction or inflammatory disease were excluded. Glycaemia, glycated haemoglobin (HbA1c), high-sensitive C-reactive protein (hsCRP), lipid profile, insulin, testosterone and gonadotrophins were measured. Insulin resistance was assessed by homoeostasis model assessment of insulin resistance (Homa IR). Waist circumference, body mass index and blood pressure were significantly higher in patients compared with controls. Glycemia, HbA1c, fasting serum insulin and Homa IR were significantly increased among hypogonadal men. In univariate analysis, testosterone levels were inversely correlated with body mass index, waist circumference, blood pressure, glycaemia, HbA1C, insulin, Homa IR and hsCRP. In multivariate analysis including all significant variables, initial testosterone level was the only independent risk factor for developing dyslipidaemia. With logistic regression, male hypogonadism was an independent risk factor for MS (P < 0.001). We conclude that low testosterone level plays a central role in the development of metabolic syndrome. Further prospective data are required to establish the causative link.

RESUMO

Acute renal failure following hunger strike has been rarely reported. We report a 47-year-old man, prisoner, who developed an acute renal failure secondary to hypovolemia and major rhabdomyolysis. Failure of hydration with persistence of oliguria and secondary pulmonary edema required hemodialysis with eventually a favorable outcome.

RESUMO

BACKGROUND: Genome-wide analyses of the genetic predisposition to type 2 diabetes mellitus (T2DM) in different isolates and populations have identified regions of interest called non insulin-dependent diabetes mellitus (NIDDM) 1, 2, 3 and 4. At the NIDDM1 locus (2q37.3), calpain-10 (CAPN10) encodes for a ubiquitously expressed protease implicated in the two fundamental pathophysiological aspects of T2DM. This is a report of the results of a study of the association of four CAPN10 polymorphisms with T2DM in the Tunisian population. PARTICIPANTS AND METHODS: A total of 222 T2DM patients with a diabetes duration of 10 years or more and 206 healthy controls were enrolled to analyze the frequency distribution of four CAPN10 polymorphisms (UCSNP-43, UCSNP-19, UCSNP-110 and UCSNP-63) using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in the Tunisian population. We also investigated the association of T2DM with different haplotypes and haplotype combinations. RESULTS: Only the A allele of UCSNP-43 showed an association with T2DM (odds ratio, OR=1.86). We also identified a novel combination of haplotypes (121/221) defined by three polymorphisms (UCNSP-43, -19 and -63) that is associated with an increased risk of T2DM (OR=2.38). CONCLUSION: In this study involving the Tunisian population, we identified genetic variants within CAPN10 that are linked with T2DM and a novel haplotype combination, 121/221, associated with an increased susceptibility to T2DM.

RESUMO

OBJECTIVE: Diabetic nephropathy (DN) is a long-term complication of both type 1 and type 2 diabetes. Genetic studies on DN have been of little help so far, since several genetic association studies have shown conflicting results. Here we report the findings of a case-control study on five SNPs in the glucose transporter 1 (GLUT1) gene. The study investigated the association of five GLUT1 genotypes and haplotypes with DN. RESEARCH DESIGN AND METHODS: All subjects, 126 DN (cases) and 273 type 2 diabetes (controls), were genotyped using the polymerase chain reaction restriction fragment length polymorphism. RESULTS: The TT and the AA genotypes of the Haell and Enh2 SNP1, increased the risk of DN. The study also identified CGT as the highest risk haplotype (4.4-fold) followed by CAT with an increased risk of DN of 2.6-fold. CONCLUSIONS: The GLUT1 gene confers susceptibility to DN in type 2 diabetes patients in the Tunisian population.

RESUMO

CONTEXT: Cardiac dysfunction is one of the most serious consequences of scorpion envenomation. The best tool to evaluate cardiac function is echocardiography, but it is not available at all emergency departments. Many studies aimed to describe biological predictive factors of cardiac dysfunction in scorpion envenomation. Troponin is one of these biomarkers but its correlation with myocarditis is not well established. The aim of this study was to evaluate correlation between troponin levels and cardiac dysfunction in moderate scorpion envenomation. METHODS: A retrospective monocentric study including patients admitted in the emergency department for moderate scorpion envenomation with troponin measurement during their early management. On arrival, an electrocardiogram and a chest X-ray were realized for all patients. RESULTS: We enrolled 132 patients with a mean age at 31.3 ± 24.4 years and a 1.35 sex-ratio. All patients had moderate systemic manifestations. There were 28 patients with clinical manifestations of cardiac dysfunction without life-threatening troubles (21.2%). Troponin was undetectable in 69 patients (56%). The mean value of troponin level (pg/ml) was higher in patients with clinical manifestations of left ventricular dysfunction (1.80 ± 3.8 vs. 0.11 ± 0.5; p = 0.02). Troponin levels were significantly higher in patients with positive T wave on electrocardiogram. CONCLUSION: In patients with moderate scorpion envenomation with positive T wave, high values of troponin suggest the presence of cardiac dysfunction.

RESUMO

OBJECTIVE: Our study aimed to determine the efficacy and safety of colistin in the treatment of ventilator-associated pneumonia (VAP) caused by pan-drug-resistant Pseudomonas aeruginosa or Acinetobacter baumanii. DESIGN: Pairwise, retrospective exposed-unexposed study. SETTING: Combined medical and surgical intensive care unit of Habib Bourguiba University Hospital (Sfax, Tunisia). PATIENTS: Sixty patients with VAP caused by pan-drug-resistant A. baumanii or P. aeruginosa matched to 60 controls with VAP caused by A. baumanii or P. aeruginosa susceptible to imipenem. All patients had normal renal function at the onset of antibiotic therapy. INTERVENTIONS: Case patients were treated by colistin intravenously and control patients were treated by imipenem intravenously. MEASUREMENTS AND RESULTS: Baseline characteristics were similar between the colistin and imipenem groups. The mean duration of antibiotic therapy for VAP was 9.5+/-3.8 days (range 5-22 days) with colistin and 8.9+/-2.8 days (range 5-20 days) with imipenem (p=0.32). A favorable clinical response to antibiotic therapy for VAP occurred in 45 patients (75%) in the colistin group and in 43 patients (71.7%) in the imipenem group (p=0.68). The time to resolution of infectious parameters after the initiation of antibiotic therapy was not statistically different between the two groups. During the antibiotic course, none of the patients in either group developed renal failure. CONCLUSIONS: We conclude that colistin can be a safe and effective option in the treatments of VAP caused by pan-drug-resistant P. aeruginosa or A. baumanii.

RESUMO

INTRODUCTION: The objective of this work was to review current data about the pathophysiology, clinical features, and treatment of thrombotic microangiopathies. CURRENT KNOWLEDGE: Thrombotic microangiopathies are microvascular occlusive disorders characterized by systemic or intrarenal aggregation of platelets, thrombocytopenia, and mechanical injury to erythrocytes. In thrombotic thrombocytopenic purpura, systemic microvascular aggregation of platelets causes ischemia in the brain and other organs. In the hemolytic-uremic syndrome, platelet-fibrin thrombi occlude predominantly the renal circulation. Thrombotic microangiopathy is a rare disorder whose varied clinical manifestations result from the formation of platelet-rich thrombi within the microvasculature and consequent tissue ischemia. The clinical features are acute renal failure, microangiopathic hemolytic anemia and thrombocytopenia. This diagnosis is of considerable importance because of the possible fulminant clinical course. Some atypical forms may be unrecognized. Plasma exchange is the current reference treatment of thrombotic thrombocytopenic purpura. However, in the light of recent publications, either infusions of concentrates of purified enzyme or more intensive immunosuppressive therapy would be more specific.

RESUMO

To identify the profile of anti-pancreas autoantibodies and elucidate the HLA DRB1, DQB1 polymorphism in Tunisian first-degree relatives of patients with type 1 diabetes, we recruited 96 relatives from 21 families with at least one diabetic child. Islet cell antibodies (ICA) were detected by immunofluorescence on monkey pancreas; glutamate decarboxylase (GADA), IA2 (IA2-A) and insulin (IAA) antibodies were measured by RIA. HLA class II DRB1 and DQB1 alleles were typed by PCR-SSP. ICA, GADA, IA2-A and IAA were found in respectively 11.5, 4.2, 5.2 and 8.3% of relatives. Twenty-two out of 96 had at least one antibody and 20 out of these 22 had a susceptibility allele (DRB1*03, DRB1*04, DQB1*02 or DQB1*0302) with or without protective allele (DRB1*11, DRB1*13, DRB1*15 or DQB1*06). All of the 5 relatives having 2 autoantibodies or more carried the DRB1*04-DQB1*0302 susceptible haplotype. In conclusion, this observational study confirms in a Tunisian population known epidemiological data and demonstrates the usefulness of follow-up to determine the predictive value of studied markers.

RESUMO

AIM: Our aim was to study the susceptibility of Streptococcus pneumoniae to antibiotics in patients with pneumococcal meningitis and to search for the prognosis factors in those patients. METHODS: We have studied retrospectively 31 cases of pneumococcal meningitis. Comparaisons were performed with univariate analysis. RESULTS: The mean age was 36.7 +/- 20.5 years (ranged: 9 and 78 years). The sex ratio was 3,4. The susceptibility of Streptococcus pneumoniae to penicillin G was affected in 10 cases (33% of isolated pneumococcus. The MIC to penicillin G was > or =2 in only one case. The hospital mortality was 26% (8/31). With univariate analysis, factors associated with death were: age > or =55 years (Ss p= 0,006, OR: 17.2 IC95%: 2.3-134), albuminorachie > or = 7 g/l (p = 0.002, OR: 22; IC95%: 1.9-2.51), shock (p = 0.031, OR: 6.7; IC95%: 1.05-42) and Glasgow Coma Score (GCS) < or =8 (p = 0.001, OR: 20; IC95%: 2.68-149). CONCLUSION: No susceptibility to penicillin G is not associated with a worse outcome in patients with pneumococcal meningitis. An age > or =55 years, albuminorachie > or =7 g/l shock and Glasgow Coma Score < or =8 at admission were determinant of the prognosis in our study.

RESUMO

BACKGROUND: Minor head injury is one of the major diagnoses requiring management in emergency departments (ED) but its squeals are not well studied in our country. OBJECTIVE: To describe the prevalence of post-concussive syndrome and its impacts on life activities, up to 6 months of follow-up, among patients having a minor head injury and discharged from ED. METHODS: A prospective bi-centric study including adults having a minor head trauma and consenting to be followed up to 6 months after discharge. The Rivermead Post-Concussion Symptoms Questionnaire (RPQ) was used at baseline, after 15 days, at 1 month, at 3 months and at 6 months post-injury to assess concussive symptoms. We also used the Rivermead Head Injury Follow-up Questionnaire (RHFUQ) to describe impacts of minor head trauma on life activities. RESULTS: There were 130 consenting patients at baseline interview. Proportion of patients describing post-concussive symptoms at baseline was 71/130. At 6 months of follow-up, post-concussive syndrome was diagnosed among 21.4 % of participants. Sustaining symptoms at 6 months post-injury were mainly anger and irritability (12.5 %). Correlations between high RPQ sum rates since 15 days' post-injury call and the sum total rates of RHFUQ were significant. The major significant impact of minor head trauma at 6 months of follow-up was among domestic activities. CONCLUSION: The two most important findings of this study were the huge proportion of patients having minor head injury and discharged from ED without any explanation of possible symptoms after head trauma and the unknown impacts on life activities.

RESUMO

OBJECTIVE: To report the clinical experience, biochemical findings, complications and maternal outcome in patients with acute fatty liver of pregnancy (AFLP). PATIENTS AND METHODS: Retrospective study over a period of 11 years (1993-2003). The diagnosis of AFLP was confirmed by liver biopsy in 15 women. However, in 7 women a medical committee that took into account clinical symptoms, and laboratory findings assessed the diagnosis. RESULTS: Were included in this study, 22 women with a mean age of 30+/-5.4 years. Only 22.7% of cases were primigravid. The mean gestational age was 36+/-2.76 weeks (range 31-41 weeks). The fetus was a male infant in 75% of cases. Ten women were admitted in the hospital without jaundice. However 15 women had developed an icterus since their hospital admission or during ICU stay. The mean SAPS II on the ICU admission was of 24.86+/-11.2 points. Biological disturbances observed were mainly: liver cytolysis in 91% of cases, a trend to hypoglycaemia in 86%, a hypoprotidemia in 66.7% and CIVD in 32%. During their ICU stay, 19 women (86.4%) developed one or several organ failures associated to the hepatic failure and 18 women required blood transfusion. After an average stay of 7.5 days, evolution was marked by the death of seven patients (31.8%). Factors correlated with a poor prognosis were: the delay of medical consultation, the development of jaundice, the development of encephalopathy, respiratory or a circulatory failure. DISCUSSION AND CONCLUSION: AFLP is a rare but life-threatening complication. Furthermore AFLP shares features with other more common and less perilous illnesses. An early diagnosis and appropriate therapy of this pathology should improve the poor prognosis in our country.

RESUMO

Newer techniques of magnetic resonance imaging (MRI) describe more accurately pituitary stalk abnormalities such as infections, infiltrative lesions and tumors. In absence of all the above mentioned etiological factors, genetics defects are suspected, mainly when other malformations are equally present. We attempt to show through 11 observations the variability of pathologies involving the pituitary stalk with their respective clinical and radiological features and associated endocrine abnormalities. This is a retrospective study of 7 men (67%) and 4 women (33%), mean age of 28 year (range: 15 to 53) in whom pituitary MRI was performed for hypopituitarism, diabetes insipidus or hyperprolactinemia. Three patients had brain MRI for an extra-pituitary condition. The pituitary MRI showed a stalk section in 3 cases (27%), atrophy in 1 case and thickening in 7 cases (67%). The pituitary stalk anomaly was associated with hyperprolactinemia in 3 cases (27%), central diabetes insipidus in 4 cases (36%), growth hormone deficiency in 4 cases (36%), adrenal insufficiency in 5 cases (45%), hypogonadism in 5 cases (45%) and hypothyroidism in one case (9%). Established diagnoses were: sellar metastasis in 2 cases (18%), Langerhans' histocytosis, tuberculosis and autoimmune hypophysitis respectively in 3 cases (9%). In 6 cases (54%), no clear etiology was found. Given the multitude of pituitary stalk pathologies, a detailed etiologic inquiry must be performed in order to detect elements able to reclassify an initially idiopathic disorder.

RESUMO

It is well known that hyperthyroidism occurs in approximately 2 to 17.5% of patients with myasthenia gravis. Hyperthyroidism may influence the clinical course of myasthenia gravis. We report the cases of two patients, a 53-year-old man and an 18-year-old woman, who had both severe myasthenia gravis and hyperthyroidism due to Graves' disease. Myasthenia gravis affected in particular facio-ocular areas with diffuse myopathy and signs of neuromuscular block on the electromyogram. In one patient, the diagnosis of thyroid disease was made three months before the diagnosis of myasthenia gravis while in the other, thyroid disease was recognized four months after myasthenia gravis. Myasthenia gravis worsened after the development of hyperthyroidism in the second patient. Both patients were given anti-cholinesterase drugs. One underwent thymectomy. Radioiodine used for the treatment of hyperthyroidism improved the symptoms of myasthenia gravis in the first patient. The association of myasthenia gravis and hyperthyroidism is more than a coincidence; our cases illustrate the difficult diagnosis and management of these diseases. Clinicians should look for myasthenia gravis in hyperthyroid patients and vice versa, especially when symptoms of myasthenia gravis or hyperthyroidism worsen.

RESUMO

OBJECTIVES: To analyze the clinico-biological manifestations, identify the causes and evaluate the outcome of patients with severe thrombotic microangiopathies admitted in a Tunisian intensive care unit. METHODS: Retrospective study over a period of 10 years (1995-2004) in an intensive care unit. RESULTS: Were included in this study 9 cases with a mean age of 29.2+/-9 years (range 15-44 years). Fever was observed in 5 patients, neurological impairment in 5 and digestive manifestations in 6. Haemolytic anaemia, thrombocytopenia and acute renal failure were observed in 100% of the cases. In our study, the aetiologies of thrombotic microangiopathies were: complicated pregnancy in 6 cases, systemic lupus erythematosus in 1 case. In contrast, no aetiology was found in 2 patients. Plasma exchange was performed in 5 patients, while 4 patients received only plasma infusion. After an average stay of 18+/-12.5 days, evolution was marked by the death 3 patients. CONCLUSION: The incidence of severe thrombotic microangiopathies is rare in Tunisian ICU. The clinical manifestations are not specific. Despite the improvement in the outcome by exogenous plasma supply, thrombotic microangiopathies with severe organ dysfunctions leading to hospitalization in the intensive care unit are associated with a high mortality rate.

RESUMO

BACKGROUND AND PURPOSE: The aim of our study was to search for the incidence, the responsible organisms and the favoring causes of death of post-traumatic meningitis (PTM). METHODS: This retrospective study was conducted over a seven-year period (January 1st, 1996 - December 31, 2002) in the ICU and the neurosurgery department of the Habib-Bourguiba University Hospital, Sfax, Tunisia. RESULTS: Over the study period, 38 patients presented PTM (0.96% of patients hospitalized for head injury), 92% of them had received antibiotic prophylaxis on admission. Mean time between head injury and the diagnosis of PTM was 9+/- 8 days (range: 2-34 days). The most common isolated organisms were multidrug resistant A. baumanii, and K. pneumoniae and reduced susceptibility S. pneumoniae. Factors predictive of prognosis in the 14 days following the diagnosis of meningitis were Glasgow coma score (GCS) on the day of diagnosis of PTM, absence of nuchal rigidity, CSF protein, CSF/blood glucose ratio, and S. pneumoniae as the causal agent of PTM. CONCLUSIONS: Antibioprophylaxis in patients with head trauma must be avoided to prevent the emergence of multidrug resistant bacteria when PTM occurs. GCS on the day of diagnosis of PTM, CSF protein concentration, CSF/blood glucose ratio, and S. pneumoniae as the causal agent of PTM are predictive factors of mortality of patients with PTM.

RESUMO

In order to estimate the prevalence of hospital-acquired infection (HAI) and research factors associated with its occurrence, a one-day prevalence survey was conducted at the Habib Bourguiba University Hospital, Tunisia. We studied 280 patients who had been present in the same ward for at least 48 h, and who had occupied a hospital bed between 17 April 2002 (midnight) and 18 April 2002 (midnight). The overall prevalence of HAI was 17.9%. The most frequently infected sites were the lungs (32%), surgical wounds (28%) and the urinary tract (20%). Microbiological documentation was available in only 28% of HAIs, and the most frequently isolated organisms were Gram-negative rods (80.8%). Results of multiple logistic regression analysis indicated that HAI is linked to the medical category, the use of intravascular devices and antibiotic prophylaxis. This survey provided information on the prevalence of HAI in Tunisian hospitals, the breakdown of infections, and HAI predisposing factors.

RESUMO

INTRODUCTION: Celiac disease is a pathology which is rarely associated with thrombosis complications. Cerebral vascular thrombosis has never been described in patients with a celiac disease. OBSERVATION: We report an observation of a 21-year-old girl with a history of celiac disease who was hospitalized in the intensive care unit for convulsive status epilepticus secondary to a cerebral venous thrombosis. The etiologic investigation of this thrombo-embolic complication revealed protein S deficit. Our patient improved under symptomatic treatment. COMMENT: This original observation confirms that celiac disease can be associated with cerebral venous thrombosis.
