Non-invasive and rapid diagnosis of type 2 diabetes mellitus based on the analysis of hair by front-face fluorescence spectroscopy.

Rapid and early detection of pathologies for screening purposes is not always easy with traditional methods. New low-cost optical techniques that are suitable for preventive detection and, more specifically, for developing countries must be developed. The objective of this work is to propose UV-VIS fluorescence of hair as a promising technique for a simple and rapid preliminary diagnosis of type II diabetes. In this work, we analyzed 130 hair samples taken from volunteers of different ages at the Habib Thameur Hospital in Tunis, Tunisia. These samples were analyzed clinically beforehand, and 50 were classified as healthy acting as a control, 24 were classified as low-level diabetics with a glycated hemoglobin A1C (HbA1c) <7%, and the other 56 were classified as high-level diabetics having an HbA1c >7%. The fluorescence of the patients' hair led to several interesting results. Indeed, a clear discrimination was obtained not only between the healthy and patients with a disease, but also a discrimination between diabetics with low levels and high levels or diabetics with and without complication. Also, a strong correlation between fluorescence spectra and glycated HbA1c for the diabetic population was clearly established. A linear discriminant analysis shows that it is possible to predict the status of test patients after having trained a fraction of the population. All these results show the ability of the front-face fluorescence (FFF) technique to detect disease and predict advanced states simply by capturing the fluorescence of the hair illuminated by a single LED. This work shows for the first time, to our knowledge, the capability of the FFF technique on hair samples for the diagnosis of diabetes.

[Etiologic profile of digital necrosis in an internal medicine department]. / Profil étiologique des nécroses digitales dans un service de médecine interne.

BACKGROUND: Digital necrosis is a frequent event in vascular pathology. They are multiple etiologies and are the translation of a general or locoregional pathology. The aim of our study was to clarify the various causes of digital necrosis in an internal medicine department. METHODS: We conducted a retrospective study of 23 cases of digital necrosis collected in the internal medicine department of the hospital Habib Thameur over a period from January 1998 to April 2011 . RESULTS: There were 16 women and 7 men with mean age of 46 years. The cardiovascular risk factors were observed in 39.13% cases. Digital necroses were interested fingers in 73.91% and toes in 30.43% of the cases. The causes were dominated by the connective diseases. The treatment was symptomatic in all cases and etiologic in only two cases. CONCLUSION: In internal medicine, the causes are dominated by connectivites. The prognosis is especially functional. It remains unfavorable in spite of the improvement of the therapeutic and etiologic care.

Nail involvement in connective tissue diseases: an epidemiological, clinical, and dermoscopic study.

BACKGROUND: The assessment of nail changes in connective tissue diseases (CTD) has been rarely explored in previous studies. The use of dermoscopy to study vascular changes in nailfolds is an interesting diagnostic technique. The aim of the study was to describe the epidemiological, clinical, and dermoscopic features of nail lesions in CTD. METHODS: A prospective study was performed at the Dermatology Department of Habib Thameur Hospital (Tunis, Tunisia) in collaboration with the Internal Medicine Department over a period of 15 months, from July 2020 to September 2021, including patients diagnosed with systemic sclerosis (SS), systemic lupus erythematosus (SLE) and dermatomyositis (DM). RESULTS: Our study included 48 patients. Nail involvement was found in 44 cases. Dermoscopic nailfold abnormalities were identified in 37 cases. The most common clinical features were ragged cuticle, nailfold erythema, and onycholysis. Additionally, splinter hemorrhage, longitudinal ridging, lunula abnormalities, melanonychia, trachyonychia, leukonychia, increase in transverse curvature, parrot beak nail, half and half nails, and onychorrhexis were described. Nailfold dermoscopy showed a normal pattern in 10 cases, a nonspecific pattern in nine cases (SLE), and a scleroderma pattern in 29 cases (SS and DM). The scleroderma pattern was further categorized into an early pattern (6), an active pattern (14), and a late pattern (9). Normal pattern was observed solely in patients in remission. The late scleroderma pattern was associated with disease duration and systemic involvement. In SLE, disease activity correlated with onycholysis, nailfold erythema, and pathologic pattern in dermoscopy. However, patients with DM displayed a positive correlation between pulmonary involvement and scleroderma pattern. CONCLUSION: Nail involvement in CTD includes a diverse range of abnormalities. Despite being nonspecific, it can provide crucial clues for establishing a diagnosis. Nailfold dermoscopy serves as a mirror for microangiopathy, enabling the detection of changes at an initial stage, and thus, it becomes a diagnostic and prognostic tool.

[Thrombosis and cancer: retrospective study of 17 cases]. / Thrombophlébites paranéoplasiques : etude rétrospective de 17 observations.

BACKGROUND: The association cancer and venous thrombosis is almost always an independent criterion of poor prognosis of cancer. Thus, venous thromboembolic disease is with infection and organ failure, one of the leading causes of death in patients with malignant disease. AIM: To identify the characteristics of the association between cancer and venous thrombosis in any patient with deep vein thrombosis of lower limbs seemingly unexplained. METHODS: This is a retrospective study from January 1994 to December 2008, concerning 17 cases of patients with deep vein thrombosis of lower limbs associated with neoplasia, hospitalized in internal medicine department at Habib Thameur hospital between a total of 290 patients with deep vein thrombosis of lower limbs. Only patients hospitalized for deep vein thrombosis of lower limbs complicated or not by a pulmonary embolism were included. RESULTS: Our study concerned 17 patients. There were 10 women and 7 men with a sex ratio (Female / Male) at 1, 42. The average age was 68.7 years, with extreme ages ranging from 40 to 90 years. Cancer has formed 6% of the causes of deep venous thrombosis of lower limbs. Eight of our patients were known to suffer from a cancerous disease. Six cases of cancers were discovered at an advanced stage of evolution with multiple metastases. In seven cases the etiological could not be achieved. Deep venous thrombosis was complicated by pulmonary embolism in four inaugural events, five patients had recurrent thrombosis, and two cases of bleeding complications were noted. CONCLUSION: Venous thromboembolism is common in cancer patients. It can be the first manifestation of cancer completely silent. The course and prognosis depend on the stage of cancer combined.

Corticoid-associated complications in elderly.

BACKGROUND: Corticosteroids are widely prescribed products in the elderly particularly in systemic diseases. Corticosteroids were indispensable in controlling a variety of disease states. Various complications associated with this drug class warrant caution and monitoring with each formulation especially with old population. AIM: To evaluate the frequency and type of side effects and complications of long-term corticosteroid therapy in the elderly. METHODS: We conducted a retrospective study of 23 patients aged 65 and older hospitalized in the internal medicine department of the Habib Thameur hospital during January 2000 to December 2004. Corticoid adverse effects were recorded throughout the follow up period. RESULTS: There are 20 women and 3 men aged 66 to 87 years with a mean age of 75.7 years. The diagnoses were 8 cases of temporal arteritis, 7 cases of rheumatoid arthritis, 3 cases of multiple myeloma, 2 scleroderma, 1 case of systemic lupus erythematosus, 1 case of retroperitoneal fibrosis and 1 case of psoriatic arthritis. We selected 66 complications. Infectious complications were found in 26 cases (39.3%), 11 cases (16.7%) of iatrogenic diabetes, arterial hypertension in 9 cases (13%), skeletal complications in both cases,psychiatric complications in two cases, ophthalmologic complications in one case. CONCLUSION: Despite lifestyle rules and adjunctive therapy, complications seem to be frequent. To minimize the disadvantages of prolonged corticosteroid treatment, regular monitoring and careful screening is imperative for the support and time.

[Rheumatoid arthritis in the elderly: ten cases report]. / La polyarthrite rhumatoïde du sujet âgé : A propos de dix observations.

BACKGROUND: The occurrence of rheumatoid arthritis (RA) in elderly is frequent. If the reality of a real difference in clinical presentation between younger and older subjects is discussed, the central point remains that the prognosis is not better for the elderly. Finally, conventional treatment is as effective and safe as in younger patients, and the same stringent targets for management of the PR used for young subjects must be applied in the elderly. AIM: To identify the characteristics of RA in the elderly in its epidemiological, clinical, radiological, evolutive and therapeutic. METHODS: We conducted a retrospective study of RA in the elderly aged 65 and over, we've compiled ten cases hospitalized over a period of 4 1/2 years in the service of Internal Medicine, Habib Thameur Hospital (Tunis). RESULTS: There were 8 women and 2 men. The average age was 70.6 years. The onset of arthritis and the disease was progressive in seven cases. An inflammatory syndrome was present in seven cases. Rheumatoid factor was positive in eight cases. Five patients were classified as stage III and IV according to the radiological classification of Steinbrocker. The treatment was based on painkillers and anti-inflammatory drugs in all cases. Long-term treatment was initiated in seven patients. The outcome was favorable in all cases. CONCLUSION: Late-onset RA is a heterogeneous framework in which multiple clinical forms deserve to be individualized and should reflect this diversity, rather than approach to the problem of global RA after 60 years.

[Takayasu's arteritis in Tunisia: a monocentric study of 11 patients]. / La maladie de Takayasu en Tunisie: etude mono-centrique de 11 cas.

BACKGROUND: Takayasu's disease is a chronic inflammatory arteritis involving large vessels in young women. AIM: To assess the clinical, laboratory, and radiological features and course of Takayasu arteritis in Tunisia. METHODS: This retrospective study analyzed 11 patients with Takayasu arteritis between 1999 and 2010 who met the criteria for inclusion proposed by the American College of Rheumatology (ACR). RESULTS: The file review identified 11 women, with a mean age at diagnosis of 29.1 years (range: 17-50 years). Our series included involvement of the aortic arch and its branches in 8 cases, while only 3 cases of the abdominal aorta. Arterial hypertension due to stenosis of the renal arteries was noted in 4 cases. Aortic insufficiency and pulmonary hypertension were noted in one case. In all, 3 patients had type I disease, 3 type V and one type IV. In all, 4 patients had glucocorticoid treatment, and one needed immunosuppressive therapy. Three patients required surgical intervention. Our patients were followed for a mean period of 67.5 months. Disease remained stable in all patients. CONCLUSION: Despite the small number of our patients, the clinical manifestations, angiographic data and course in our study were similar to those in other reported series.

[Special features of systemic sclerosis in men]. / Particularités de la sclérodermie systémique chez l'homme.

BACKGROUND: Systemic sclerosis (SS) is a generalized disorder of connective tissue and microvasculature characterized by tissue fibrosis and obliteration of the vessels. Several features of systemic scleroderma in men are discussed in the literature. AIM: To investigate the initial clinical features, evolution and prognosis of systemic sclerosis in men. METHODS: Patients with systemic sclerosis based on ACR's criteria were included. In this retrospective study we compared a cohort of men to a cohort of women, diagnosed between 2000 and 2010 in department of internal medicine. RESULTS: Fifty four patients were included amongst which nine men. The mean follow-up duration was 39.5 months. A higher proportion of cardiac, renal and lung involvement were noted at diagnosis Localized cutaneous sclerosis was predominant in men. CONCLUSION: This work has highlighted several features of systemic sclerosis encountered in men. These results warrant confirmation by analyzing a larger population.

[Urinary tract infections in elderly]. / Les infections urinaires chez les personnes âgées.

BACKGROUND: Urinary tract infections (UTI) in elderly are frequent and polymorphic clinical symptoms. This is a public health problem both in support and cost they generate. AIM: To study the epidemiological, clinical, paraclinical and therapeutic aspects of UTI in the elderly. METHODS: We conducted a retrospective study of 50 cases of UTI in the elderly collected in the Internal Medicine Department at Habib Thameur Hospital between January 2002 and December 2006 (Group I). We compared this group to another group of patients aged below 60 years also explored for UTI in the same service and during the same period (Group II). RESULTS: They were 37 women and 13 men in group I and 41 women and 9 men in the group II. In group I, the average age was 74.10 ± 6.7 years, in group II 43.58 ± 11.26 years. In group I, 35 patients (70%) showed no evidence of suspicion of a UTI on admission. 15 patients (30%) were admitted for suspected UTI. In group II, 36 patients (72%) showed no evidence of suspicion of a UTI on admission. 14 patients (28%) were admitted for suspected UTI. Urological abnormalities underlying the UTI, detected by ultrasound, were more frequent in Group I (40%) than in Group II (12%). Second-line antibiotics, due to the likely resistance of the microorganism, had to be prescribed in 16% cases in Group I vs. 4% of cases in Group II. The evolution under antibiotic treatment was marked by the occurrence of 3 deaths and transition to renal failure in 4 cases for Group I. In Group II, the outcome was favorable in all cases. CONCLUSION: Urinary tract infection is a significant factor in morbidity and mortality in the elderly. Female is much more concerned than male. Clinical manifestations of UTI are often crude and misleading in a pathological and poly polymedicated patient. The preventive arm accounts for most of the management of urinary tract infection in the elderly.

[Quality of life in ankylosing spondylitis]. / Qualité de vie au cours de la spondylarthrite ankylosante.

BACKGROUND: Ankylosing Spondylarthritis (AS) involves by its frequency and its repercussion on the functional capacity an important handicap and deterioration of the patients quality of life. AIMS: To evaluate the handicap and the quality of life during the AS and to seek the predictive factors of the deterioration of this quality of life. METHODS: A prospective study relating to 50 patients recruited in the Department of Rheumatology of F. B. Hospital of Monastir during 6 months period (Mars to September 2008). The studied parameters were the quality of life evaluated by a specific sore (ASQOL) and a generic score (SF-12). Also the physical, social and economic felt handicap was evaluated using a qualitative scale. Predictive factors (clinical, biological and radiological) of the quality of life were carried out. RESULTS: Our patients are divided in 42 men and 8 women with an average age of 38.9 ± 10.7 years. The average duration of AS is of 11.9 ± 7.6 years. The average of ASQOL is of 11.9 ± 4 (extremes: 0- 17). The average of physical SF12 is of 29.8 ± 6 (21.7-53.2) and of mental SF-12 of 35.3 ± 6.6 (22.5-55.8). The physical, social and economic felt handicap was considered to be average or important in respectively 88%, 72% and 86% of the cases. The predictive factors of a high ASQOL (faded quality of life) are absence of occupation, high BASMI, a high number of painful articulations and high BASFI, BASDAI, BASG, BASRI and EVA total pain. The factors associated to the alteration of the quality of life according to SF-12'S are male sex, professional statute, high number of painful articulations and high BASDAI, BASFI and BASRI. CONCLUSION: Our study shows the important deterioration of the quality of life in AS patients. The existence of the predictive factors of quality of life primarily related to the functional capacity of the patients and to the disease activity implicates an early and adequate disease management in order to decrease this repercussion.

Epidemiological, clinical, and therapeutic characteristics of Behçet's disease: a monocentric study in Tunisia.

INTRODUCTION: to describe the epidemiological, clinical, therapeutic and evolving characteristics of Behçet´s disease and identify prognostic factors. METHODS: we have realized a retrospective, single-center study, conducted over a period of 26 years and including 130 patients presenting Behçet´s disease and hospitalized in an Internal Medicine Department. RESULTS: the mean age of the Behçet´s disease at onset was 30.3 ±8.8 years and that at diagnosis was 34.6 ±9.4 years. The sex ratio (male/female) was 2.5. The mean delay of diagnosis was 53.5 months. Oral aphthosis was constant. The frequency of the manifestations was: genital aphtosis 71.5%, pseudofolliculitis 84.6%, erythema nodosum 11.5%, positive pathergy test 50%, ocular disease 36.9%, venous thrombosis 30%, arterial disease 4.6%, joint damage 30.8%, neurological disease 19.2% and digestive disease 0.8%. The male gender was significantly associated with ocular involvement (p =0.02), venous disease (p =0.01) and occurrence of relapses (p =0.01). The mean follow up was 68.5 ± 77.3 months. The poor survival prognostic factors were male gender, ocular involvement, venous disease, cardiovascular disease, a duration of follow up ≤12 months and a diagnostic delay ≤ 24 months. Conclusion: improving the prognosis of Behçet´s disease requires a shortening of the time to diagnosis, multidisciplinary collaboration, intensive treatment of functional threats, regular monitoring, and patient adherence.

Arterial Hypertension in Systemic Lupus Erythematosus: About 40 Cases.

The aim of this study was to determine the prevalence and the etiologic profile of hypertension (HTN) in systemic lupus erythematosus (SLE). A retrospective analysis was performed on 153 patients with SLE who attended our center for 16 years from January 2000 to December 2016. The diagnosis of SLE was established according to the classification criteria of the American College of Rheumatology in 1990. The prevalence of HTN in patients with SLE was 26.1% (40/153)' with an average delay of appearance of 21 months. There were 37 women and three men with a mean age of 46' eight years (20-70). HTN was associated with lupus nephritis (n = 8)' other renal impairments (n = 6)' and corticosteroid treatment (n = 20). Essential HTN was found in six cases. Cardiovascular factors associated with HTN were: diabetes (n = 14)' sedentary life (n = 15)' obesity (n = 12)' and dyslipidemia (n = 8). Main clinical manifestations associated with HTN were: arthralgia/arthritis (24 cases)' cutaneous involvement (22 cases)' and hematological manifestations (16 cases). Anti-phospholipid syndrome was found in 12 cases. Coronary artery disease' arteritis of lower limb' and transient ischemic attacks complicated the course of HTN in six patients. Angiotensin-converting-enzyme inhibitors were the most commonly used drug for treatment in this group. HTN was frequently associated with corticosteroid treatment in this study. We feel that the use of corticosteroids should be avoided as far as possible in all patients with SLE.

Myxofibrosarcoma of the leg: A diagnostic challenge.

We should keep in mind slowly growing malignancies when the lesion is located close to the synovial regions of the extremities. The diagnosis of certainty of myxofibrosarcoma is histological and is based on the demonstration of the myxoid matrix, fibroblastic cells with a curvilinear arrangement of the vessels.
