In Tunisia, five Bahloul spaced sections, Bargou, Jerisa, Guern Halfaya, Kherij and Gafsa were analyzed for biostratigraphy （foraminifera and radiolarians） and major and trace elements. This high-resolution biostratigraphic and chemostratigraphic integrated analyses for the Late Cenomanian-Early Turonian Bahloul Formation provide new insight into the palaeoceanographic evolution of the southern Tethyan margin. Relative low abundance of related terrigenous Ti/Ai and K/ Al ratios and enrichment of some productivity proxies such as Ba, Cu, and Ni （organic matter related trace elements） suggests that the Bahloul, deposited during a relatively short period （0.5 Ma）, was of relatively elevated primary productivity and minimal detrital input. While higher D＊ values concurrent with lower Ti/AI ratios are interpreted as caused by enhanced fluvial material contribution, due to more humid climate during the OAE-2. Enhanced humidity triggered probably fluvial influxes, resulted in a sluggish water circulation and consequent anoxic/euxinic conditions favoring the preservation of organic matter at the bottom. Enrichments in redox-sensitive trace metals U, V, and Mo in the Bahloul Formation deposits and redox indices, such as V/（V＋Ni）, U/Th, V/Cr, and Ni/Co, indicate that oxygen-restricted conditions prevailed during the Late Cenomanian to earliest Turonian times and correlate well with relative abundances of some foraminiferal and radiolarian paleo- environmental relevant indicators. High Ba~ values and Uauth may indicate anoxic conditions at least at the water-sediment interface during the Bahloul Formation deposition and provide information about low to moderate sulfate-reduction reactions.

Hemothorax caused by rupture of aortic aneurysm or aortic dissection is an uncommon manifestation and carries a high mortality rate. We report two cases of 75- and 80-year-old men, who were referred to our department for exploration of a left pleural opacity. Thoracentesis produced a hemorrhagic fluid. The computed tomography scan revealed an aortic dissection type B of Stanford in the first case and an aneurysm of the descending thoracic aorta in the second patient. Emergency operation was performed in the first case but the patient died of multiple organ failure 48 hours after surgery. Aortic dissection or aneurysm can result in a hemothorax especially in patient with favourable conditions such as elderly patient and systemic hypertension. Diagnosis relies on computed tomography (CT) scan and echocardiography.

Background: Drug-induced acute kidney injury is a common situation in clinical practice. Many treatments are involved and they are even more aggressive when associated with a predisposing factor such as diabetes. We aimed to investigate clinical features of acute drug-induced kidney injury in diabetics in order to clarify renal prognosis. Methods: This was a descriptive and analytical retrospective study including diabetics who presented drug-induced acute kidney injury, conducted in our department during the period from 1986 to 2015. Acute kidney injury was classified according to Kidney Disease Improving Global Outcomes criteria. We analyzed medical records of patients. Results: 31 patients were included with mean age of 65.41 years and gender ratio M/F at 0.93. Diabetes was type 2 in 97% of cases. Mean previous creatinine clearance was 39.33 ml/min/1.73 m2. Drugs involved were blockers of renin-angiotensin system (35%), aminoglycosides (16%), non-steroidal anti-inflammatory (16%), diuretics (13%), lipid-lowering agents (10%), rifampicin (6%) and ifosfamide (3%). Extracellular dehydration was present in nine cases (29%). Main drug combinations were with diuretics in 16 cases (52%) and with ACE inhibitor or ARB in eight cases (26%). Oligo anuria was observed in 5 cases (16%). Proteinuria with urine strips was objectified in 25 cases (81%). Acute kidney injury was grade 3 in 24 cases (77%), grade 2 in three cases (10%) and grade 1 in four cases (13%). Renal survival at 102 months was 57%. Identified renal prognosis factors were serum phosphorus >1.47 mmol/l (p = 0.01), proteinuria at urine strips (p = 0.042), dehydration (p = 0.013), oral antidiabetic treatment (p = 0.038), intravenous rehydration (p = 0.021) and insulin (p = 0.006). Conclusion: Drug-induced acute kidney injury is potentially serious in diabetics. Prevention is essential to improve the prognosis of this renal damage.

Introduction: The rheumatoid polyarthritis is the most frequent chronic polyarthritis. It affects essentially woman between 40 and 60 years old. Rheumatic subcutaneous nodules and tenosynovitis are usually associated with seropositive symptomatic rheumatoid polyarthritis. However, it is rare that they constitute the essential clinical expression of the disease. Case report: A 60-year-old woman was hospitalized for tumefaction of the dorsal face of the right hand evolved two months before. The clinical examination was found isolated subcutaneous nodules. The anatomopathological exam of one nodule ended in its rheumatoid origin and the MRI of a second one confirmed a tenosynovitis. Anti-CCP antibodies were positive. The patient has never suffered from arthralgias. The evolution was favourable under corticosteroid therapy, methotrexate and colchicine. Discussion: Rheumatic subcutaneous nodules and tenosynovitis are usually associated with seropositive symptomatic rheumatoid polyarthritis. It is rare that they constitute the essential clinical expression of the disease. Conclusion: The extra-articular appearances of the rheumatoid polyarthritis must not be underestimated especially since they can constitute—even rarely—the essential clinical expression of the disease.

Primary laryngeal tuberculosis is rare. It can manifest as a malignancy delaying the diagnosis and the therapeutic management. We report the case of a 34-year-old immunocompetent man whose plaints were fever, sweat and dysphonia. There were no adenopathy, nor hepatosplenomegaly. Several blood cultures were negative. Laboratory studies showed an inflammatory syndrome. In addition, the bacteriological examinations of sputum and urine in search of Mycobacterium tuberculosis were negative. Laryngoscopy confirmed the presence of a thickness of the right vocal cord and an ulcer in the hemilarynx. The histological examination revealed tuberculoid granulomas suggestive of tuberculosis. The culture from vocal cord tissue for Mycobacterium tuberculosis was positive. No other focus of tuberculosis was found on X-ray and computed tomography. Treatment by a combination of isoniazid, rifampicin, pyrazinamide induced a total resolution of symptoms.

The adult onset Still’s disease is a rare inflammatory pathology of unknown pathogeny. The clinical features are variable. The diagnosis is difficult since exclusion of infectious, systemic and tumoral pathologies should be done. The articular complications are frequent and can be revelatory of this pathology. The articular prognosis depends on the diagnosis delay and the treatment efficiency. Our study aims to analyze different aspects of articular manifestations complicating adult onset Still’s disease to define epidemiological, clinical and evolving characteristics of these complications. It was a cross-sectional study concerning 20 cases of adult onset Still’s disease diagnosed from 1990 to 2015 in the internal medicine A department of Charles Nicolle Hospital in Tunis, meeting Yamaguchi criteria. We identified clinical, radiological, evolving and therapeutic profile of the articular manifestations occurred in these patients. There were 13 women and 7 men. The average age was 25 years. The arthralgias were reported in all cases;while, the arthritis interested fifteen patients. A hand deformation was found in four patients. A wrist ankylosis was noted in one case and a flexion elbow in one patient. The standard articular radiographs were normal in twelve cases. The treatment associated essentially non-steroidal anti-inflammatory and/or corticosteroids and/or methotrexate. Concerning the evolving profile, the monocyclic form was present in 25% of the cases, the intermittent form in 45% and the chronic articular form in 30% of our patients. The adult onset Still’s disease is rare and heterogeneous. The articular disturbances are frequent and have various outcomes.
