Ketosis-onset diabetes in Tunisian adults: immunological markers and beta-cell function

The aim of this study in Tunisia was to classify ketosis-onset diabetes in adult patients. All patients aged >/= 30 years without known diabetes, presenting with ketosis and admitted to our department were studied. Patients with secondary or gestational diabetes and those on corticoid therapy or with coinciding infection were excluded. The data included clinical characteristics, immunological markers and beta-cell function. Of the 63 patients, islet-cell antibodies were present in 27.0%, glutamic acid decarboxylase antibodies in 25.4% and thyrosin phosphatase antibodies in 19.0%. beta-cell functional reserve was preserved in 54.0%. Our results confirm that patients with ketosis-onset diabetes mellitus in adulthood are a heterogeneous group

[Amelanotic spitzoid melanoma of the digit: a case report]

Melanomas of digit is rare, accounting for 1% of all cutaneous melanomas. We report a new case. Our purpose is to discuss the clinicopathological characteristics and the difficulties encountred in establishing diagnosis of this rare tumor. We report the case of a 25 years old woman, who consulted for nodular and ulcerated lesion of the right index, located in the external face of the metacrapo-phalangial joint. The nodule was biopsied and histopathologic exam concluded to spitzoid melanoma. The surgical margins were involved. The patient refused surgical recovery. She consulted 3 years later with axillary lymph nodes. A wide excision of the tumor with lymph node biopsy were made. Histological study concluded to a tumoral residu incompletely excided with lymph node metastases. Amputation of the second digit with dissection of the axillary lymph nodes was made. The surgical margins were tumor free. Lung metastases appeared with a follow up of two months. The patient died early after starting chemotherapy with Deticen. In our report, clinical presentation was misleading causing a diagnosis and therapeutic delay. Pathologically, all the histological types of melanoma were described in the digit except spitzoid melanoma

[Actinomyces peripheral pulmonary nodule]

Actinomycosis is a chronic suppurative infection usually caused by Actinomyces israelii. Pulmonary involvement is a rare condition. The diagnosis is often delayed because of various appearances and the difficulty in microbiologic identification. We report a case of pulmonary actinomycosis in a 58 year old man who presented training respiratory symptoms. Clinical and radiological picture was mimic lung cancer. The definite was made after thoracic surgery. The patient's clinical condition improved with antibiotic therapy based on penicillin G then amoxicillin for 6 months. Through this new case, we discuss the possibilities of improvement of diagnosis and therapeutic approach of pulmonary actinomycosis by reducing of invasives procedures

[Clinical and etiological features of primary adrenal insufficiencies in children]

The chronic primary adrenal insufficiency or Addison's disease is uncommon in children and belongs generally to a complex syndrome. Study of the clinical and aetiological features of primary adrenal insufficiencies in children. In a retrospective study, we reviewed clinical and diagnostic data of all cases of Addison's disease admitted within a period of 15 years [from January 1991 to December 2006], in a department of paediatrics. Cases due to congenital adrenal hyperplasia were excluded. 6 cases of Addison's disease were diagnosed. Five patients are the product of consanguineous marriage. The age at the diagnosis of adrenal insufficiency yarned from 15 months to 9 years 8 months. The adrenal insufficiency was associated to Allgrove syndrome in three cases, to autoimmune polyendocrinopathy type 1 in one patient and to probable peroxisomal disease in another one. The etiological disease was not determined in one patient. A substitutive hormonal therapy was conducted in all patients. During a mean follow-up of 26 months, two adrenal crises were noted. larger studies about Addison's disease are needed to confirm the preponderance of the Allgrove syndrome

[Ambulatory pediatric morbidity. Evaluation of one year activity of consultation in department of Pediatrics, emergency and consultations of children's hospital of Tunis]

Pediatric morbidity has been the subject of many studies, nevertheless those concerning with ambulatory morbidity are rare. The subject of this study is to establish the epidemiologic profile of patients. Identify the encountered pathologies and their frequency, precise morbidity characteristics and raise difficulties in the diagnostic and therapeutic management. In this retrospective study we reviewed the data of 4387 children that have consult for the first time external consultation of the department of Pediatric External Consultations and Emergency [PUC] of the Children's Hospital of Tunis during the year 2003. The 4387 patients benefit from 7323 consultations which represent 44.3 per cent of the total of consultations of the year 2003 [16 507]. 59.4 percent of the studied population was male [sex ratio = 1.2] and two thirds were aged under 6 years old. The main motif of consultations was recurrent bronchopneumonia [15.2 percent], cutaneous disease [6.2 percent], vomiting [6.1 percent] and abdominal pain [5.6 percent]. 3.2 percent of the children were admitted. Ambulatory morbidity was dominated by four pathologies: digestive 16 percent, pulmonary 14.9 percent, neurologic 6.7 percent and hematologic pathothologies [6 percent]. Gastro-oesophageal reflux was the major digestive disease followed by acute diarrhea [10.6 percent]. The principal pulmonary disease were bronchopneumonia [60.5 percent], acute bronchitis [21.6 percent] and asthma [14.4 percent]. 59.9 percent of the neurologic pathology were represented by seizures. 28.4 percent of the seizures were feverous. Anemia is the most frequent hematologic pathology [55.1 percent]. It was caused by iron deficiency in 87 percent of cases. The endocrinologic pathology is essentially represented by the short stature. We suggest to informatize medical data so it would be more exploited for studies, to make more complementary explorations available in the Children's Hospital of Tunis and to decentralize the management of the simples diseases

[Complement hereditary deficiency in bacterial meningitis. Study of 61 Tunisian adults and litterature review]

Sixty one Tunisian adult patients with bacterial meningitis were screened for complement deficiency. Functional activity of the classical and the alternative pathways of complement [CH50 and AP50 respectively] were measured according to standard haemolytic procedures. Serum concentrations of C3 and C4 were determined by nephelometry. Late complement component [C5-C9] and properdin concentrations were assessed by double-ligand ELISA. Complement deficiency was found in eight patients [13%]: Seven had late complement component deficiency [three C7 deficiency, two C5 deficiency, one C6 deficiency and one C8 deficiency] and one had partial properdin deficiency. Patients with late complement component deficiency had a mean age of 24 years [range 17-32 years]. All deficient patients had meningococcal meningitis. Recurrent meningitis was reported in half of the patients. Our findings demonstrated a high prevalence of complement deficiency in Tunisia suggesting that screening for hereditary complement deficiency should be performed in case of bacterial meningitides and meningococcal disease patients

Infection a VIH et autoanticorps

Humoral and cellular abnormalities were rapported by some authors during HIV infection. In our study we were interested to test the presence of autoantibodies in 45 sera of seropositif patients for HIV. We found anticytoskelet antibodies in 24,5% and antinuclear antibodies in only two cases. Rhumatoid factors were detected by latex and Waaler-Rose tests in 24,5% while anticardiolipin antibodies were observed in 15,5% of our patients. Natural autoantibodies searched by Elisa, were noted with a high prevalence. The presence of autoantibodies has not any clinic or pronostic involvment
