[Refractory Sweet syndrome complicated by monoclonal gammopathy of undetermined significance]. / Syndrome de Sweet récidivant compliqué de gammapathie monoclonale de signification indéterminée.

The association between Sweet syndrome and monoclonal gammopathy of undetermined significance (MGUS) is exceptional. We report the case of a 44 years-old woman in whom recurrent Sweet syndrome was complicated by monoclonal gammopathy of undetermined significance (MGUS) after 3 years of evolution.

L'association entre syndrome de Sweet et gammapathies monoclonales de signification indéterminée (MGUS) est exceptionnelle. Nous rapportons l'observation d'une patiente âgée de 44 ans chez qui un syndrome de Sweet d'évolution récurrente, s'est compliqué par l'apparition d'une gammapathie monoclonale de signification indéterminé après 3 ans d'évolution.

[Cryoglobulinemia in a Tunisian internal medicine department]. / Cryoglobulinémie : expérience dans un service de médecine interne tunisien.

AIM: Cryoglobulinemia is characterized by multiple organ involvement, mainly including the skin, liver, kidneys, and peripheral nerves. Our aim was to investigate the demographic, clinical, and serologic features, as well as survival in a group of 16 Tunisian patients with cryoglobulinemia. RESULTS: The study included 12 women and 4 men, and their mean age was 41 years. In all but two, the cryoglobulinemia was associated with another disease. These included lupus for 9, Sjögren syndrome for 2, and polyarteritis nodosa for one. They also included infectious diseases: 3 patients with hepatitis B virus infection, one with hepatitis C virus infection, one with parvovirus B19, and another with lymph node tuberculosis. Only one case of lymphoproliferative disease was noted. General symptoms were present in 81% of the patients, cutaneous vasculitis in 43%, peripheral vascular-Raynaud phenomenon in 37%, joint polyarthralgia or arthritis in 62%, renal involvement in 68%, neuropathy in 25%, lung involvement in 56%, gastrointestinal involvement in 37%, and finally cardiac involvement in 31%. In some cases it was difficult to determine if the clinical signs were attributable to cryoglobulinemia or the underlying pathology. The course was favorable under treatment for 5 patients, while 7 patients became sicker and 5 finally died. CONCLUSION: Cryoglobulinemia is underdiagnosed. Treatment depends on the severity of the lesions and the underlying disease.

[Treatment of tuberculosis]. / Traitement de la tuberculose.

The aim of this article is to give practicing physicians a practical approach to the treatment of latent and active tuberculosis. Most patients follow TB standard treatment recommended by WHO that depend on category of patient. It is a combination of four essential tuberculosis drugs of the first group: isoniazid, rifampicin, pyrazinamid and ethambutol; in some cases streptomycin can replace ethambutol. This initial phase of intensive treatment is followed by a consolidation phase. Drugs should be administered in the morning on an empty stomach one hour before meals. Treatment of latent tuberculosis (TB) infection is an important component of TB control programs. Preventive treatment can reduce the risk of developing active TB.

[Symptoms and natural history of hospital chronic obstructive pulmonary disease]. / Symptômes et histoire naturelle de la broncho-pneumopathie chronique obstructive en milieu hospitalier.

BACKGROUND: Since few years, the data describing the chronic obstructive pulmonary disease (COPD) have changed and new concepts have emerged. AIM: To study the clinical characteristics and outcome of patients with COPD in a Tunisian population. METHODS: It is a retrospective study including 150 patients with COPD admitted at the pulmonary department of Charles Nicolle Hospital in Tunis, during a period of ten years. RESULTS: Data from 150 patients hospitalized at the pulmonary department of Charles Nicolle Hospital in Tunis, were analyzed. They were 126 men and 24 women with a mean age of 67 years. Tobacco was the predominant risk factor. Eighty-two (55%) patients were classified GOLD stage IV at diagnosis. The number of exacerbation varied from 1 to 7 with an average higher in patients classified as stage IV (p = 0.007). CONCLUSION: The COPD is pathology of smoking men. Comorbidities and exacerbations prevalence increase according the disease severity. In fact, better knowledge of exacerbations etiologies allows considering better measurement of prevention.

[Lupus and pregnancy: study of 26 cases, an internal medicine department experience and review of the literature]. / Lupus et grossesse : expérience d'un service de médecine interne à propos de 26 cas et revue de la littérature.

OBJECTIVE: To study the maternal and fetal outcomes in women with systemic lupus erythematosus. PATIENTS AND METHODS: A retrospective study of 26 pregnancies in 15 systemic erythematosus patients diagnosed before or during pregnancy regarding to American College of Rheumatology criteria in a single reference center. RESULTS: The mean patient age was 31.52 years (24-39 years). The mean interval from the diagnosis of the systemic lupus erythematosus to pregnancy was 4.2 years. Eight pregnancies were planned. The flare rate of lupus during pregnancy was 31%, life birth rate was 65% and fetal loss rate was 35%. DISCUSSION AND CONCLUSION: As an increase in disease activity can occur during pregnancy and because of a higher rate of obstetrical complications in patients with lupus, it is important to carefully plan pregnancy. Pregnancy in lupus patients must be closely monitored by a multispeciality care of the patients.

[An unusual toothache!]. / Une douleur dentaire inhabituelle!

INTRODUCTION: Dental pain is a frequent reason for consulting. It may have non-odontogenic causes such as lesions of vascular, neurologic, muscular, or bone structures. The diagnosis and management of this acute or chronic pain syndrome may be difficult. We report a case of atypical dental pain leading to the diagnosis of a plasmocytic mandibular tumor revealing a multiple myeloma. CASE REPORT: A 50-year-old female patient consulted for dental pain during the 3 previous months. Bilateral mandibular swelling was noted during the clinical examination. Radiological examinations revealed a tumoral process associated with osteolytic lesions. The pathological examinations of biopsy samples revealed plasmocytic proliferation. A myelogram and immunoglobulin electrophoresis supported a diagnosis of multiple myeloma with kappa light chains. DISCUSSION: Discovering a mandibular tumor with lytic lesions is an indication for an etiological assessment and screening for a blood disease. A mandibular plasmacytoma may be isolated or present as a multiple myeloma, justifying a complete initial assessment. The bone localization of a plasmacytoma is a bad prognostic factor for survival for patients presenting with multiple myeloma.

[Lung mycosis in non neuropenic patients]. / Infections pulmonaires mycosiques chez des patients non neutropéniques.

UNLABELLED: Lung mycosis is rare. Diagnosis and treatment must be done the earliest possible. METHODS: It is about a retrospective study on clinical records including patients hospitalized for lung infection. RESULTS: From 2008 to 2011, 16 patients (13 men and three women, average age 42 years) developed a pulmonary infection. Twelve of our patients had respiratory or extrarespiratory histories. None of our patients had a neutropenia. The diagnoses were lung aspergilloma in four cases, invasive lung aspergillosis in three cases, allergic bronchopulmonary aspergillosis in three cases, mucormycosis in three cases, trichosporonosis in a case, actinomycosis in one case and penicilliosis in one case. An antifungal treatment consisting in amphotericin B or itraconazole was given to four patients and six patients, respectively. Surgery was chosen for six patients. The evolution was good for 12 patients, one presented renal failure, and three patients died.

[Retinal vasculitis. Epidemiological, clinical and etiological features]. / Les vascularites rétiniennes: profils épidémiologiques, cliniques et étiologiques.

PURPOSE: To study the epidemiological and clinical features of noninfectious retinal vasculitis (NIRV). METHODS: We analyzed 128 consecutive patients with NIRV, collected over 15 years (1993-2007) in an ophthalmological reference university hospital in Tunis, Tunisia. Data were analyzed regarding associated systemic disease, ocular syndromes, anatomic features (type and topography of vessel and type of capillaropathy), age and sex. The results of the etiologic work-up were based on the Levy-Clarke and Perez classification. RESULTS: A total of 240 cases of NIRV (128 patients) were collected (mean age: 32; sex ratio: 2.6). It was bilateral in 93.7% of cases. The mean visual acuity (VA) was 20/50 (range: 20/800-20/20). NIRV was mainly venous (84.1%), diffuse (57%), with a mixed capillaropathy (40.2%). There were complications in 56.25% of the cases, mainly macular edema (48.1%), vascular occlusion (25.9%), optic atrophy (22.2%) and cataract (19.2%). NIRV was idiopathic in 15.6% of the cases, characterized by a predominance of young subjects (mean: 38 years old), males (sex ratio: 4), VA at 20/25, and edematous periphlebitis in 100% of cases. There were ocular disorders in 12.5% of the cases and systemic disease in 72% of the cases, with a predominance of Behçet disease (BD): 53.9% of all patients and 81% of systemic disease with predominant venous features. In 48.3% of cases, VA was less than 20/200, due to BD in 48% of the cases. CONCLUSION: In NIRV, the etiologic work-up is oriented on anatomic presentation, based on fluorescein retinal angiography, and requires an interdisciplinary approach. In young adults with retinal phlebitis, BD is suggested first.

[Late revelation of homocysteinuria: clinical, biological and progressive aspects]. / Homocystéinurie à révélation tardive : aspect clinique, biologique et évolutif.

UNLABELLED: Homocysteinuria is a metabolic disorder with defect in genes encoding for methionine metabolism enzymes. The clinical features consist in: ophthalmic, neurological, orthopedic and vascular manifestations. It is generally diagnosed in childhood. Vascular involvements characterize adult's forms. We report one case. OBSERVATION: A 26-year-old man, who has lentis ectopia and a recent epilepsy, was hospitalized for deep vein thrombosis. Regarding the marfanoid phenotype and the high level homocysteinemia (231 micromol/L), homocysteinuria was suspected. Amino acid chromatography and reduced CBS activity were used to confirm the diagnosis. Vitamin enriched diet with vitamin B6 and folates has reduced slightly the homocysteine level. CONCLUSION: Homocysteinuria must be diagnosed early since a simple vitamin supply could ameliorate prognosis and decrease complications.

[Acute rhabdomyolysis during pneumococcal pneumonia: two cases]. / Rhabdomyolyse aiguë au cours des pneumonies à pneumocoque. A propos de deux observations.

Acute rhabdomyolysis is a clinical and biological syndrome generally with a toxic or traumatic cause. Only 5% of cases are infectious, and rarely in relation to a pneumococcal infection. We report two cases of acute rhabdomyolysis which developed in patients with severe Streptococcus pneumoniae pneumonia. No other cause could be identified in these two patients aged 32 and 37 years. Rhabdomyolysis was discovered in the first patient because of acute kidney failure and elevated serum transaminase levels. The second patient presented an inflammatory edema affecting the soft tissues. Blood cultures isolated a pneumococcus in both patients. The rhabdomyolysis regressed favorably in both patients despite the transient renal failure in the first patient. Prognosis is generally poor for rhabdomyolysis during the course of pneumococcal pneumonia, with increased morbidity and mortality for these infections. Early detection of bacteriemia enables rapid and adequate treatment and prevention of renal failure.
