[Systemic lupus erythematosus presenting as Stevens-Johnson syndrome]. / Lupus érythémateux systémique se présentant comme un syndrome de Stevens-Johnson.

Stevens-Johnson syndrome and toxic epidermal necrolysis are life-threatening dermatological conditions. Their most common cause is medication. However, in a small proportion of patients these dermatological conditions could be the first presentation of systemic lupus erythematosus. We now describe a 34-year-old patient who presented with manifestations of Stevens-Johnson as a first feature of systemic lupus erythematosus. Systemic lupus erythematosus reveled by Stevens-Johnson syndrome has been infrequently reviewed in the previous literature. This diagnosis should be considered when cutaneous adverse drug reactions occur without clear drug causality.

[Tumoral form of abdominal actinomycosis: a retrospective case series of seven patients]. / Actinomycoses abdominales à forme tumorale : une série rétrospective de sept observations.

PURPOSE: Abdominal actinomycosis is an uncommon chronic infectious disease due to Actinomyces, a Gram-positive bacteria. This saprophytic bacteria of digestive tract and genital mucosa can occasionally become pathogenic mimicking a digestive neoplasia. The aim of this study was to underline diagnostic features of abdominal actinomycosis and to summarize data about clinical, diagnostic and therapeutic approach of this type of infection. PATIENTS: From January 1995 to December 2007, retrospective data concerning patients with abdominal actinomycosis who were followed-up in the University Hospital Sahloul (Sousse, Tunisia) were analysed. RESULTS: Seven patients with abdominal actinomycosis were identified during the study period. All presented with an abdominal mass. The diagnosis of actinomycosis was obtained after surgical resection in all cases. The histological study permitted the diagnosis in six cases, and the surgical samples grew up Actinomyces in two patients. For the five patients who received prolonged and adapted antibiotic therapy, a favourable outcome was observed. CONCLUSION: Actinomycosis must be included in the differential diagnosis of invasive abdominal lesions with "malignant appearance".

A misdiagnosed nail bed melanoma.

Nail bed melanoma or subungual melanoma is frequently misdiagnosed compared to other melanoma in other anatomic sites. We report the case of a 48-year-old woman presenting with a dystrophic and pigmented lesion of her fourth finger nail. This initial presentation had been mistaken for onychomycosis, but biopsy of nail bed and nail matrix confirmed nail bed melanoma. This case is presented to help increase the awareness of atypical presentations of acral melanoma.

Predictive factors of glucocorticosteroid treatment failure in severe acute idiopathic colitis.

INTRODUCTION: The purpose of our study was to determine clinical, biological or endoscopic factors that could predict glucocorticosteroid treatment failure in acute colitis. PATIENTS AND METHODS: Fifty-four Tunisian Caucasian patients with acute idiopathic colitis (ulcerative colitis in 53 patients, Crohn's colitis in 1 patient) have been evaluated. Non-therapeutic response was defined as over 6 bowel movements per day, blood visible to the naked eye in stools on the fifth day after admission or the development of a complication inducing a resort to surgery. Predictive factors were assessed using bivariate and multivariate analysis. RESULTS: Thirty-nine patients (72.2%) had no medical response. In univariate analysis, predictive factors of therapeutic failure were: male sex, tobacco, previous history of colitis attacks, bowel movements per day over seven at admission and on day three, and pulse rate over 90/mn, temperature over 38 degrees C, systolic blood pressure below 11 on day 3 and on day 5 after admission. In multivariate analysis, bowel movements over seven per day on day 3 of hospitalization and male sex independently predicted a failure of glucorticosteroid treatment. CONCLUSION: Bowel movements per day over seven on day 3 of hospitalization and male sex were the independently predictive factors of failure of glucocorticosteroid treatment.

[Primary hypertrophic osteoarthropathy without cutaneous involvement (Currarino's disease)]. / Ostéoarthropathie hypertrophiante primitive sans atteinte cutanée (maladie de Currarino).

INTRODUCTION: Hypertrophic osteoarthropathy (HOA) is a syndrome associating hippocratic fingers, arthropathy and periostosis of long bones. Currarino's disease, considered at present as a clinical form of primary HOA, is characterized by the absence of pachydermia. OBSERVATION: A 24-year-old Caucasian man, consulted for a painful swelling of both ankles that had developed over the past year. Clinical examination revealed hippocratic fingers without pachydermia. The ankles were swollen. The X-rays showed periosteal apposition and an acro-osteolysis. In view of this triad: arthropathy, hippocratic fingers and periostosis, primary HOA without cutaneous involvement or Currarino's disease was diagnosed. The search for a secondary cause remained negative. Clinical improvement was obtained after 15 months with non-steroidal anti-inflammatory drugs (NSAID) and colchicine. COMMENTS: Although exceptional, primary HOA without cutaneous involvement is a genetic disease which must not be ignored.

[Esophageal mucocele: report of 2 pediatric cases]. / Mucocèle oesophagienne à propos de deux observations pédiatriques.

Two cases of esophageal mucocele in pediatric patients are reported: two children of 5 and 9 years respectively underwent surgical isolation of the esophagus and esophagocoloplasty for caustic stenosis related to accidental ingestion of caustic soda. Clinical pattern of mediastinal compression was proved with cervical fistulous tract in one case. In both cases, thoracic computed tomography was a sensitive imaging method to demonstrate the mucocele and its extension. Esophageal mucocele is rarely described in children, especially following esophageal corrosive stricture.

[Mucocele of the appendix. Retrospective study of 10 cases]. / Les mucocèles appendiculaires. Etude rétrospective à propos de 10 cas.

PURPOSE: The purpose of our work was to assess the value of abdominal sonography (US) and computed tomography (CT) in the preoperative diagnosis of appendiceal mucocele. MATERIAL: and methods. We retrospectively reviewed 10 cases of mucocele of the appendix, 7 cases without pseudomyxoma peritonei, and 3 cases with pseudomyxoma peritonei. All cases were investigated radiologically by plain film and US, barium enema was performed in 3 cases and CT in 5 cases. RESULTS: Mucoceles of the appendix are rare and their clinical presentation is not specific. US confirms the appendicular involvement, but often poses the differential diagnosis with acute inflammation, abscess or localized appendicular peritonitis. CT appears as a mandatory examination since it allows accurate preoperative diagnosis period. In this series, the diagnosis was made preoperatively in the 5 cases where CT had been performed. CONCLUSION: US is useful to confirm the abnormal pattern of the appendix but does not allow accurate diagnosis of mucocele. CT is more specific and accurate for diagnosis of mucocele of the appendix.

[Anal metastasis of colonic adenocarcinoma?]. / Métastase anale d'un adénocarcinome du côlon?

Two cases of sigmoid and anal adenocarcinoma are reported. The two patients were treated by abdominoperineal resection of the rectum and resection of the sigmoid colon. The relationship between colonic adenocarcinoma and anal adenocarcinoma is not obvious but possible. The various mechanisms of tumoral spread are discussed and the most frequent mechanism seems to be cellular exfoliation.

[Palpebral capillary hemangioma and amblyopia. Apropos of 2 cases]. / Hémangiome capillaire palpébral et amblyopie. A propos de 2 cas.

Periorbital capillary hemangiomas of childhood can produce visual axis occlusion and anisometropia, resulting in amblyopia. We report our experience performing surgical resection of periorbital capillary hemangiomas. Partial resection of hemangiomas was performed in two infants under five months of age, and permitted clearing of the visual axis. This immediate effect is necessary to prevent amblyopia. Surgical resection should be considered a treatment option for managing periorbital capillary hemangiomas which threaten vision.

[Hydatic cysts of the liver ruptured into the thorax. Diagnostic and therapeutic aspects]. / Les kystes hydatiques du foie rompus dans le thorax. Aspects diagnostiques et thérapeutiques.

Hydatic cysts of the liver can rupture into the thorax. The aim of this work was to demonstrate how abdominal access can be used in most cases. We report 44 cases of hydatic cysts which ruptured into the thorax among a series of 1411 hydatic cysts of the liver operated between 1974 and 1995. Abdominal ultrasound and chest x-ray provided the diagnosis preoperatively in 35/42 operated cases (one case of spontaneous elimination of a hydatic membrane via a cutaneous orifice and one case of preoperative death). Thoracophrenolaparotomy was used in 12 cases, thoracotomy with laparotomy in 6, thoracotomy alone in 5 and laparotomy alone in 19. Pulmonary resections were performed in 18 cases. No procedure could be performed in one patient who died at the beginning of surgery. A breach in the diaphragm was repaired in 41 cases. The dome of the cyst was resected in 29 cases and complete pericystectomy was performed in 12. There were 7 post-operative deaths. There were no deaths in the abdominal access patients. All emergency problems were controlled with abdominal access. Thoracic access was reserved for specific cases.

Surgical management of hepatocellular carcinoma in genetic haemochromatosis.

From 1975 to 1989, 51 patients presenting with hepatocellular carcinoma complicating genetic haemochromatosis were managed in our institution. Twenty-one patients underwent a laparotomy. Laparotomy was limited to surgical exploration or palliation in 8 patients in whom the tumour was deemed unresectable. Thirteen patients underwent either a partial hepatectomy (11 patients) or a total hepatectomy and liver transplantation (2 patients). Actuarial survival at 1 and 3 years following partial hepatectomy was 56% and 40% respectively. There was one hospital death in the resection group and in the transplant group. Only 3 patients have remained free of tumour recurrence after a mean follow-up of 18 months. Common clinical and histological features for patients with this condition included masculine gender, age 50 years or above, 10 or more years of history of diagnosed genetic haemochromatosis, high alcohol intake, and grade III or IV hepatic fibrosis.

[Value of continuous measurement of mixed venous oxygen saturation (SVO2) during coronary angioplasty]. / Intérêt de la mesure en continu de la saturation en oxygène du sang veineux mêlé (SVO2) pendant l'angioplastie coronaire.

Mixed venous oxygen saturation (SVO2) is an haemodynamic parameter of cardiovascular function. The object of this study was to measure SVO2 during percutaneous transluminal coronary angioplasty (PTCA) with prolonged balloon inflation in order to evaluate haemodynamic tolerance more precisely in two groups of patients. Twenty-six patients undergoing PTCA were divided into two groups: Group I, N = 15, with single vessel disease and good left ventricular function (EF: 61.63 +/- 10.1%); Group II, N = 11, with triple vessel disease and poor left ventricular function (EF: 48.05 +/- 14%; p < 0.05). Continuous monitoring of SVO2 with an oximetrix fiber optic catheter was performed in all patients during PTCA. Irrespective of the duration of balloon inflation, a significant correlation was observed between the changes in cardiac output and VSO2. Given that arterial oxygen pressure, global oxygen consumption and haemoglobin concentrations remained constant during balloon inflation, SVO2 was an indicator of cardiac output.

[Vascular complications in infectious endocarditis. Apropos of 86 cases]. / Complications vasculaires dans l'endocardite infectieuse. A propos de 86 cas.

During a 20 year period, 285 patients were hospitalised for infectious endocarditis (IE) in the Department of Cardiology of the Ernest-Conseil Hospital in Tunis and 86 of them, i.e. 30%, developed a vascular complication (VC). Among these 86 patients, there were a total of 108 lesions, including 52 neurological complications, 14 peripheral acute ischemic syndromes, 16 peripheral arterial aneurysms, 9 aortic aneurysms, 7 pulmonary embolisms, 6 splenic infarctions and 4 coronary lesions. The mortality in this patient group proved to be slightly greater than in the series as a whole, in particular concerning patients with multiple lesions and those with an artificial valve. No prognostic difference was seen between patients with a VC of aneurysmal type and of ischemic type, but the presentation and severity of lesions was very variable. The vascular complication was a presenting feature of IE in almost 40% of cases. The organism found most often was the streptococcus, above all in ischemic type IE as well as in the total patient group. Similarly, the preferential site was aortic, above all for aneurysmal type IE. Ultrasonography revealed a higher incidence of vegetations in this series of patients, above all in ischemic type VC, but anatomical studies have shown this to be an investigation of moderate sensitivity and poor specificity, poorly correlated from a prognostic standpoint with the risk of embolism. The conclusion of the study is above all the need to prevent such complications: embolic complications by early antibiotic treatment and valve replacement and aneurysmal complications by methodical routine angiographic evaluation and appropriate treatment.
