RESUMEN
BACKGROUND: This study was initiated to evaluate, for the first time, the performance and quality of the influenza-like illness (ILI) surveillance system in Tunisia. METHODS: The evaluation covered the period of 2012-2015 and used different data sources to measure indicators related to data quality and completeness, representativeness, timeliness, simplicity, acceptability, flexibility, stability and utility. RESULTS: During the evaluation period, 485.221 ILI cases were reported among 6.386.621 outpatients at 268 ILI sentinel sites. To conserve resources, cases were only enrolled and tested for influenza during times when the number of patients meeting the ILI case definition exceeded 7% (10% after 2014) of the total number of outpatients for the week. When this benchmark was met, five to 10 patients were enrolled and sampled by nasopharyngeal swabs the following week. In total, The National Influenza Center (NIC) received 2476 samples, of which 683 (27.6%) were positive for influenza. The greatest strength of the system was its representativeness and flexibility. The timeliness of the data and the acceptability of the surveillance system performed moderately well; however, the utility of the data and the stability and simplicity of the surveillance system need improvement. Overall, the performance of the Tunisian influenza surveillance system was evaluated as performing moderately well for situational awareness in the country and for collecting representative influenza virologic samples. CONCLUSIONS: The influenza surveillance system in Tunisia provided pertinent evidence for public health interventions related to influenza situational awareness. To better monitor influenza, we propose that ILI surveillance should be limited to sites that are currently performing well and the quality of data collected should be closely monitored and improved.

Hemophagocytic lymphohistiocytosis (HLH) is an hyperinflammatory state resulting from increased secretion of proinflammatory cytokines, which are responsible for clinical, biological and cytological manifestations. OBJECTIVE: The aim of our study is to describe the epidemiological, clinical, biological, etiological and evolutionary profile of HLH in Tunisia. METHODS: A retrospective study that involved patients, with images of hemophagocytosis in myelograms analyzed at the laboratory of biological hematology of the University Hospital "Hédi-Chaker" of Sfax-Tunisia, followed at these departments: hematology, internal medicine, department of infectious-diseases and department of gastroenterology, (June2017- May2021). First, we identified all patients with hemophagocytosis images. Secondly, we selected the patients who fulfilled the diagnostic criteria of the HLH-2004-score. RESULTS: Nineteen patients were included in this study. Nine men and 10 women with a mean age of 37.95 years. Fever was present in all patients. Organomegaly was described in 74% of cases. The most frequent cytopenia was anemia (100%). Hypertriglyceridemia was noted in 79% of cases and hyperferritinemia (> 500 ng/mL) was ubiquitous. In myelogram, 68% of patients had slides showing numerous or very numerous images of hemophagocytosis. The infectious pathology was the most common cause of HLH (42%). No cause was found in 10% of cases. The corticosteroid therapy at a dose of 1 mg/kg/day was prescribed in 89% of our patients. The overall evolution was favorable in 58% of cases. The mortality was not associated with the causal pathology (p=0.218). CONCLUSION: Secondary HLH is likely to be under-recognized, which contributes to its high morbidity and mortality. Early recognition is crucial for any reasonable attempt at curative therapy.
RESUMEN
BACKGROUND/OBJECTIVES: Tuberculosis is a multisystem disease that might affect any organ. Abdominal tuberculosis (ABT) represents 5-17% from all extrapulmonary tuberculosis (EPT) sites. We aimed to study the clinical, laboratory and evolutionary features of ABT cases and to identify predictive factors associated with ABT. METHODS: We conducted a retrospective study including all patients hospitalized in the infectious diseases department for EPT between 1991 and 2019. We studied the characteristics of ABT cases, and we compared them with other EPT cases. RESULTS: We identified 519 patients with EPT, among whom 86 (16.6%) patients had ABT. There were 58 females (67.4%). Peritoneal tuberculosis was the most common clinical form of ABT (68.6%), followed by intestinal tuberculosis (18.6%). Patients aged 60 years and above were significantly less affected with ABT (odds ratio (OR) = 0.2; p = 0.001). The revealing systemic symptoms including fever (OR = 2.04; p = 0.006), weight loss (OR = 2.5; p < 0.001) and anorexia (OR = 1.7; p = 0.021) were significantly more frequent among ABT patients. Inflammatory markers including C-reactive protein levels (37 [10-89] mg/l vs 10 [4-57] mg/l; p < 0.001) and erythrocyte sedimentation rates (43 [15-95] mm/h vs 27 [15-60] mm/h; p = 0.044) were significantly higher among ABT cases. Multivariate logistic regression analysis showed that anorexia (adjusted OR (AOR) = 1.9; p = 0.015) and pulmonary involvement (AOR = 3.3; p = 0.002) were independent predictors of higher rate of ABT. Concomitant involvement of neuro-meningeal (AOR = 0.18; p = 0.001) and osteo-articular (AOR = 0.2; p = 0.01) sites, 40-59 (AOR = 0.2; p < 0.001) and ≥60 (AOR = 0.2; p < 0.001) age groups as well as hemoglobin rate (AOR = 0.7; p < 0.001) were independently associated with lower rate of ABT. CONCLUSIONS: Anorexia and pulmonary involvement were independent predictors of higher rate of ABT. Concomitant involvement of neuro-meningeal and osteo-articular sites, 40-59 and ≥60 age groups and hemoglobin rate were independently associated with lower rate of ABT.

Background: Tuberculosis (TB) has become a public health problem among elderly in developing countries with the gradual increase in life expectancy. Aim/Objective: This study aimed to analyze the prognosis factors and chronological trends of TB in elderly in Southern Tunisia. Methods: A retrospective study was conducted. All TB patients aged ≥60 years, recorded in the Center of TB Control between 1995 and 2016, were included. Chronological trends of TB were analyzed by calculating the correlation coefficient of Spearman (Rho). Multivariate analysis was done by binary logistic regression (Adjusted Odds ratio (AOR); CI; p) to determine the independent risk factors associated with unsuccessful outcome in elderly. A p value <0.05 was considered as statistically significant. Results: Overall, 512 new elderly TB cases were notified between 1995 and 2016, with an average of 23.3 new cases/year. The mean TB incidence rate for elderly was 2.31/100,000 population/year. The case-fatality rate of 8.6%. Multivariate analysis showed that factors independently associated with unsuccessful outcome among elderly patients were age between 80 and 89 (AOR = 4.5; [95% CI: 2, 10.2]; p < 0.001), male gender (AOR = 2.2; [95% CI: 1.1, 4.4]; p = 0.026) and neuro-meningeal involvement (AOR = 4.6; [95% CI: 1.4, 14.8]; p = 0.011). The incidence of TB in elderly patients increased significantly from 0.95/100,000 population in 1995 to 2.17/100,000 population in 2016 (Rho = 0.48; p = 0.024). Discussion: A better understanding of TB features in elderly and its chronological trends overtime would facilitate to put in place, in the national TB control program, strategies geared towards this group of people.
RESUMEN
OBJECTIVE: Brucella prosthetic valve endocarditis is a rare but a life-threatening complication of brucellosis. It remains a diagnostic challenge. Optimal treatment of Brucella prosthetic valve endocarditis is debated. Available data is limited to case reports or small case series. The purpose of this study was to systematically review all published cases of Brucella prosthetic valve endocarditis in the literature. METHOD: A systematic review of PubMed database, Google, Google Scholar, and Scopus (From January 1974 to the present) for studies providing epidemiological, clinical and microbiological data as well as data on treatment and outcomes of Brucella prosthetic valve endocarditis was performed. RESULTS: A total of 51 reported cases were reviewed. Brucella melitensis (45%) and Brucella abortus (11.7%) were the most frequently isolated species. Most common type of prosthesis valve was mechanical prothesis (84.3%) and ten patients had double valve prosthesis (19.6%). Fever and dyspnea were present in 100% and 37.2% of the cases, respectively. The diagnosis was set with echocardiographic finding in 30 cases (93.7%), which revealed vegetation in 27 cases (84.3%). Most used antibiotics were rifampicin, doxycycline and aminoglycoside or cotrimoxazole. No deaths were noted in patients treated by combined medical and surgical treatment, but mortality was noted in 27.7% of the cases treated by antibiotics alone (p = 0.006). CONCLUSION: This systematic review highlights diagnostic challenges and demonstrates that surgery improved outcome by reducing mortality in patients treated with the combined surgical and medical treatment option. Brucellosis should be considered in the differential diagnosis of prosthetic valve endocarditis in patients residing in or traveling to areas of endemicity.
RESUMEN
INTRODUCTION: Tuberculosis is a multisystem disease that may affect any organ or tissue. Tuberculous meningitis (TBM) is the most severe form of tuberculosis and commonly affects the brain. We aimed to study the epidemiological, clinical, therapeutic and evolutionary features of TBM among adults and to compare them with other forms of extrapulmonary tuberculosis. METHODS: We conducted a retrospective study including all patients hospitalized for extrapulmonary tuberculosis in the infectious disease department in Sfax, Tunisia between 1993 and 2018. We specified the particularities of TBM cases, and we compared them with other extrapulmonary tuberculosis cases. RESULTS: We encountered 78 patients diagnosed with TBM, among 519 patients with extrapulmonary tuberculosis (15%). The median age was 36 years (23-50) years. There were 44 females (56.4%). In comparison with other forms of extrapulmonary tuberculosis, fever [odds ratio (OR)=4.4; p<0.001], asthenia (OR=3.4; p<0.001) and anorexia (OR=2.3; p=0.001) were significantly more frequent in TBM patients. Adverse effects of antitubercular therapy were more frequent among TBM patients (OR=3.1; p<0.001). The mean duration of antitubercular therapy was 15 (12-20) months. Recovery occurred in 66 cases (84.6%), complications in 44 cases (56.4%) and death in 7 cases (9%). Comparison of the disease evolution showed that complications (OR=7.4; p<0.001) and mortality rates (OR=10.7; p<0.001) were significantly more frequent in TBM patients, while recovery was significantly more frequent in other sites of extrapulmonary tuberculosis patients (OR=0.5; p=0.02). CONCLUSIONS: In our country, TBM remains a disabling disease. Despite antitubercular therapy, the prognosis was more severe with the occurrence of not only complications but also a high mortality rate in comparison with other forms of extrapulmonary tuberculosis. When clinical and laboratory features suggest the diagnosis of TBM, clinicians should look for tuberculosis elsewhere in the body.
RESUMEN
Mucormycosis is a life-threatening disease responsible for a high mortality rate. The disease usually affects immuno-compromised patients. While all sites might be involved, gastrointestinal disease is rare, occurring for 5% to 13% of all mucormycosis cases. We report herein the fifth case of splenic and gastric mucormycosis revealed after gastric perforation and the first case occurring among an immuno-competent patient, and we review all reported cases of splenic mucormycosis by searching PubMed publications till October 2020. The literature search yielded 27 cases of splenic mucormycosis including our case. The majority of the cases had underlying immuno-compromised conditions, except for 6 cases, including ours. A male predominance was noted (22 cases). Involvement of the spleen and the stomach was rare, occurring among four immuno-compromised patients. The outcome was death in more than half of the cases. Splenic and gastric mucormycosis is a rare disease. The diagnosis of splenic mucormycosis should be considered in front of splenic lesions suggesting abscess or infarction, especially among immuno-compromised patients.

Objective: To study the clinical characteristics and imaging features of breast tuberculosis (TB) and to describe treatment. Material and Methods: A retrospective study including all patients hospitalized in the infectious diseases department for breast TB between 1997 and 2018. Results: Twenty-two women, with a mean age of 39±12 years, were identified. In total, 18 patients were multiparous (81.8%). Both lump and mastalgia were the presenting symptoms in 19 cases (86.3%). Ipsilateral axillary lymphadenopathy was noted in 14 cases (63.6%). The most common finding on ultrasound was a well or poorly defined mass lesion, noted in 17 cases (77.2%), followed by fistulous tracts in seven cases (31.8%). Mammography showed focal, asymmetric breast density in 17 cases (89.5%) and diffuse in two cases (10.5%). The diagnosis was confirmed based on the presence of epithelioid cell granulomas and caseous necrosis in 13 cases (59.1%). Patients received antitubercular therapy for a mean duration of 11±5 months. The disease evolution was favorable in 20 cases (91%). There were two relapsing cases (9%). Conclusion: Breast TB should be considered in the differential diagnosis of young patients presenting with palpable lump with axillary lymphadenopathy, especially in endemic regions. The diagnosis confirmation usually requires an excision biopsy providing histological or bacteriological evidence.
RESUMEN
STUDY DESIGN: This was a retrospective study. PURPOSE: The aim was to compare the clinical, laboratory, radiological, and evolutionary features of tuberculous spondylodiscitis (TS) and brucellar spondylodiscitis (BS). OVERVIEW OF LITERATURE: Clinical presentation of spondylodiscitis varies according to the underlying etiology, among which brucellosis and tuberculosis represent the primary cause, in endemic countries. Only a few studies have compared the characteristics between TS and BS. METHODS: A retrospective study was conducted using the data of all patients hospitalized for TS and BS in the infectious diseases department between 1991 and 2018. RESULTS: Among a total of 117 patients, 73 had TS (62.4%) and 44 had BS (37.6%). Females were significantly more affected with TS than males (56.2% vs. 22.7%, p<0.001). Fever (72.7% vs. 45.2%, p=0.004) and sweating (72.7% vs. 47.9%, p=0.009) were significantly more frequent among patients with BS. The median erythrocyte sedimentation rate was significantly higher in the TS group (median, 70 mm/hr; interquartile range [IQR], 45-103 mm/hr) than in the BS group (median, 50 mm/hr; IQR, 16-75 mm/hr) (p=0.003). Thoracic involvement was significantly more frequent in the TS group (53.4% vs. 34.1%, p=0.04), whereas lumbar involvement was significantly more frequent in the BS group (72.7% vs. 49.3%, p=0.01). Initial imaging findings revealed significantly higher frequencies of posterior vertebral arch involvement, vertebral compaction, and spinal cord compression in the TS group. Percutaneous abscess drainage (20.5% vs. 2.3%, p=0.005) and surgical treatment (17.8% vs. 2.3%, p=0.01) were more frequently indicated in the TS group, with a significant difference. CONCLUSIONS: A combination of clinical, laboratory, and radiological features can be used to distinguish between TS and BS while these patients await diagnosis confirmation.
RESUMEN
Tuberculosis remains a public health issue worldwide. Identifying its risk factors, such as vitamin D deficiency, is mandatory so as to target the preventive strategies. We aimed to study the association between vitamin D deficiency and extrapulmonary tuberculosis. We conducted a case-control study including all cases of extrapulmonary tuberculosis hospitalized in the infectious diseases department over a two-year period from April 2017 until April 2019. We included 45 cases of extrapulmonary tuberculosis and 45 controls matched by gender and age. Vitamin D deficiency was significantly more frequent among cases (80% vs 37.7%; p < 0.001), with an odds ratio (OR) of 6.5 (IC95% = 2.5-16). The mean levels of vitamin D were significantly lower among cases (11.9 ± 8.8 vs 22.3 ± 11 ng/mL; p < 0.001). In the multivariate analysis, we found that vitamin D deficiency was an independent predictor of extrapulmonary tuberculosis (OR = 6.13; p < 0.001). The cutoff value of vitamin D predictor of extrapulmonary tuberculosis was 18.5 ng/mL which was associated with a sensitivity of 80% and a specificity of 62%. Our study provides strong evidence that vitamin D deficiency was an independent predictor of extrapulmonary tuberculosis. More studies are needed in order to evaluate the potential preventive role of vitamin D and the benefit of possible supplementation.

INTRODUCTION: Tuberculosis (TB) is a communicable disease common worldwide. Influencing factors in TB outcomes include socio-demographics, as well as disease-related and treatment-related factors. This study aimed to analyze the prevalence trends of unsuccessful treatment outcomes in Southern Tunisia during 1995-2016 and to identify their risk factors. METHODS: This was a retrospective study including all notified cases from the tuberculosis center reporting registers in Southern Tunisia between 1995 and 2016. RESULTS: Overall, 2771 TB cases were notified. Unsuccessful treatment outcomes were noted in 196 cases (7%). Unsuccessful treatment outcome was associated with male gender (OR=1.4; p=0.023), elderly status (≥60 years, OR=2.3; p<0.001), joints and bones site (OR=2.2; p=0.002) as well as meningeal involvement (OR=2.4; p=0.023). Lymph node (OR=0.4; p<0.001) and therapy duration ≥6 months (OR=0.003; p<0.001) were statistically associated with lower rate of unsuccessful outcome. Multivariate regression analysis showed that elderly status (AOR=2.3; p<0.001), meningeal involvement (AOR=2.2; p<0.027) as well as bone and joints involvements (AOR=2; p=0.027) were independently associated with unsuccessful outcome. Trends analysis showed that the case-fatality rate significantly increased from 1995 to 2016 (Rho=0.4; p=0.032). CONCLUSIONS: The high prevalence of unsuccessful outcome suggested important inadequacies in the TB program. An effective strategy to improve therapeutic education of patients with TB is therefore urgently needed.
RESUMEN
The treatment of acute osteomyelitis is becoming more challenging since the emergence of community-acquired methicillin-resistant Staphylococcus aureus. We collected data on all patients with acute osteomyelitis caused by this germ over a period of 21 years (January 1995-December 2016) and we analyzed the peculiarities of this disorder. Our case series includes 15 children, with an average age of 9 years. All patients had affected lower limb. Local trauma was reported in 8 cases and skin carriage in 4 cases. Acute onset was reported in 12 cases associated with pseudo-paralysis of the affected limb. One patient had Staphylococcus aureus pulmonary infection with signs of septicopyemia. Blood culture was positive in 8 cases. In one case PCR assay for detection of Panton-Valentine leukocidin was performed with positive result. All these patients underwent surgical debridement and received secondarily adapted empirical antibiotic therapy. Outcome was good in 8 cases and poor in the other cases, with transition to a chronic state in 6 cases and one case of death. Pathological fracture was reported in 3 cases. Osteomyelitis cause by community-acquired methicillin-resistant Staphylococcus aureus is associated with a pejorative outcome. Recognizing the clinical and paraclinical signs of these infections is essential for a specific and early therapeutic management.

BACKGROUND: Worldwide, many more males than females were diagnosed with tuberculosis (TB) and died from it globally. In light of this, examining the gender differences among patients with TB is crucial to institute effective prevention, coverage and treatment. AIM: To analyze gender differences in the epidemiological, clinical and evolutionary specificities of TB in Southern Tunisia. METHODS: We conducted a retrospective study including all new cases of TB of any age, diagnosed between January 1995 and December 2016. Data were collected from the regional register of TB at the Center of Tuberculosis Control of Sfax, Southern Tunisia. RESULTS: We recorded 2771 new cases of TB. The sex ratio was 1.2. We noted 1160 new cases with pulmonary TB (PTB) (41.9%). Males were more likely to have PTB than females (Odds Ratio (OR)=2.5;p<0.001), while extra-pulmonary TB (EPTB) was more common in females (OR=0.4;p<0.001). Lymph node (OR=2.6;p<0.001), cutaneous (OR=2.3;p<0.001) and abdominal TB (OR=2;p<0.001) were significantly more frequent in females. Pleural TB was significantly more common in males (OR=1.2; p<0.001). Case fatality rate was significantly higher in males (OR=1.7;p=0.02). Females experienced recovery more frequently (OR=1.3;p=0.04). Treatment duration was significantly higher in females (8.88±3.6months vs.8.41±3.2months; p<0.001). Between 1995 and 2016, the age standardized notification rate (ASNR) of TB (Rho=0.68; p<0.001) and EPTB (Rho=0.59 p=0.003) had significantly increased in females, while it had not significantly changed in males. CONCLUSION: Our study highlighted higher burden and morbidity in males in TB cases in Southern Tunisia. National TB programs should actively focus on these facts with more routine diagnostic and screening targeting males.

INTRODUCTION: Tuberculosis affects commonly the lungs, but any other organs can be affected as well. Urogenital tuberculosis is usually misdiagnosed. In this perspective, we aimed to give an update on the epidemiological, clinical and evolutionary features of urogenital tuberculosis in Southern Tunisia. METHODS: We conducted a retrospective study including all patients with extrapulmonary tuberculosis notified during the period from 1992 to 2017 in Southern Tunisia. We specified the particularities of urogenital tuberculosis cases, and we compared them with other extrapulmonary tuberculosis cases. RESULTS: Overall, we analyzed 240 cases with urogenital tuberculosis, among 1702 patients with extrapulmonary tuberculosis (14.1%). There were 121 women (50.4%). The mean age was 49±17 years. Multifocal tuberculosis was noted in 29 cases (12.1%). There were 169 cases with urinary tract tuberculosis (70.4%). Chronological trends analysis showed that the median age at diagnosis increased significantly (Rho=0.41; p=0.039) and the number of urogenital tuberculosis declined during the study period, without a statistical significance (Rho = -0.07; p=0.721). Compared to other extrapulmonary tuberculosis sites, patients aged 60 years and above (OR=2.7; p<0.001) and coming from rural areas (OR=1.4; p=0.021) were more frequently diagnosed with urogenital tuberculosis. Treatment duration was significantly longer in patients with urogenital tuberculosis (10.13±3.79 vs 9.20±3.77 months; p<0.001). As for the disease evolution, relapse was significantly more frequent in patients with urogenital tuberculosis (OR=4.1; p=0.045). CONCLUSIONS: Although decreasing trends over time were noted, the prognosis of urogenital tuberculosis was more severe compared to other extrapulmonary tuberculosis sites.
RESUMEN
AIM: To illustrate the various clinical features and management of presumed tuberculous uveitis in an endemic area in Tunisia. METHODS: This is a retrospective study including 14 patients (26 eyes) diagnosed with presumed tuberculous uveitis at the Department of Ophthalmology Habib Bourguiba University Hospital of Sfax-Tunisia. RESULTS: Mean age at onset was 31.7 years. Uveitis was bilateral in 86 % of cases (12 eyes). Panuveitis was the most common manifestation and represented 50% of cases (13 eyes). Ocular findings include mutton-fat keratic precipitates in 35% of cases (9 eyes), posterior synechiae in 31% of cases (8 eyes), vitritis in 81% of cases (21eyes), multifocal choroiditis in 23% of cases (6 eyes), periphlebitis in 27% of cases (7 eyes), and macular edema in 42% of cases (11eyes). Anti-tubercular treatment was prescribed in all patients and was associated with systemic corticosteroids in 71% of cases (10 patients). After a mean follow-up of 16.27 months (range, 6-36), inflammation was controlled with improvement in visual acuity. Recurrence developed in 7 % of cases (1 patient). CONCLUSION: In the present study, posterior synechiae, vitritis, multifocal choroiditis, and retinal vasculitis are the most common manifestations of tuberculous uveitis in tuberculosis endemic area in Tunisia. These manifestations are suggestive of a tubercular cause of uveitis and merit specific treatment.

BACKGROUND: Multidrug resistance (MDR) is a growing global problem in bacterial community-acquired urinary tract infections (CUTIs). We aimed to propose an easy-to-use clinical prediction model to identify patients with MDR in CUTI. METHODS: We conducted a retrospective study including 770 patients with documented CUTI diagnosed during 2010-2017. Logistic regression-based prediction scores were calculated based on variables independently associated with MDR. Sensitivities and specificities at various cutoff points were determined, and the area under the receiver operating characteristic curve (AUROC) was computed. RESULTS: We found MDR Enterobacteriaceae in 372 cases (45.1%). Multivariate analysis showed that age ≥70 years (adjusted odds ratio [aOR], 2.5; 95% confidence interval [CI], 1.8-3.5), diabetes mellitus (aOR, 1.65; 95% CI, 1.19-2.3), history of urinary tract surgery in the last 12 months (aOR, 4.5; 95% CI, 1.22-17), and previous antimicrobial therapy in the last 3 months (aOR, 4.6; 95% CI, 3-7) were independent risk factors of MDR in CUTI. The results of Hosmer-Lemshow chi-square testing were indicative of good calibration of the model (χ2 = 3.4; P = .49). At a cutoff of ≥2, the score had an AUROC of 0.71, a sensitivity of 70.5%, a specificity of 60%, a positive predictive value of 60%, a negative predictive value of 70%, and an overall diagnostic accuracy of 65%. When the cutoff was raised to 6, the sensitivity dropped (43%), and the specificity increased appreciably (85%). CONCLUSIONS: We developed a novel scoring system that can reliably identify patients likely to be harboring MDR in CUTI.
RESUMEN
BACKGROUND: The role of Ramadan fasting (RF) as a predictive factor of urinary tract infection (UTI) recurrence was controversially discussed in the literature. AIM: The present study aimed to identify the prognosis factors of recurrent UTIs. METHODS: Data were retrospectively collected from patients with UTI diagnosed at the infectious diseases department and its affiliated outpatient department in Hedi Chaker University Hospital, Sfax, Tunisia, between 2010 and 2017. Kaplan-Meier method was used to generate recurrence-free survival (RFS) curves for first episode of UTI diagnosed in two groups: during and outside Ramadan, which were compared using Log-rank test for statistical inference. Univariate and multivariate Cox proportional hazards regression models were used to identify UTI recurrence factors (sex, age, age group, season, comorbidities, first UTI episode diagnosed during Ramadan, UTI requiring hospitalization, length of hospital stay, nosocomial UTI, clinical presentation). RESULTS: During the follow up, among the 867 patients with UTI, 105 (12.1%) developed a recurrent UTI one. The RFS median [95% confidence interval] was 60 [40 to 82] days. Survival curves showed that patients with UTI diagnosed during Ramadan had shorter RFS compared with those diagnosed outside of Ramadan (32 vs. 60 days, respectively, p=0.002). RF (hazard ratio = 2.96; p = 0.033) and diabetes mellitus (hazard ratio =1.6; p = 0.033) were independently associated with UTI recurrence in multivariate Cox regression analysis. CONCLUSION: Recurrent UTI was a prevalent and challenging condition among patients with UTI. Diabetes mellitus and RF had a prognosis value for recurrence in UTI.

We report a case of invasive mucormycosis in 52 year-old woman. CT-scan and magnetic resonance imaging found a partial right sinus thrombosis associated with homolateral ethmoidal and maxillary sinusitis with submucosal inflammation. Histopathological examination of excised tissue was positive for mucormycosis. Our patient was treated by surgical debridement and a combination of amphotericin B and caspofungin, with a good outcome.
RESUMEN
BACKGROUND: Tuberculosis (TB) is a public health problem worldwide. Characterizing its trends over time is a useful tool for decision-makers to assess the efficiency of TB control programs. We aimed to give an update on the current chronological trends of TB in Southern Tunisia from 1995 to 2016 and to estimate future trajectories of TB epidemic by 2030. METHODS: We retrospectively collected data of all notified TB new cases by the Center of Tuberculosis Control between 1995 and 2016 in South of Tunisia. Joinpoint Regression Analysis was performed to analyze chronological trends and annual percentage changes (APC) were estimated. RESULTS: In the past 22 years, a total of 2771 cases of TB were notified in Southern Tunisia. The annual incidence rate of TB was 13.91/100,000 population/year. There was a rise in all forms of TB incidence (APC = 1.63) and in extrapulmonary tuberculosis (EPTB) (APC = 2.04). The incidence of TB increased in children and adult females between 1995 and 2016 (APC = 4.48 and 2.37, respectively). The annual number of TB declined in urban districts between 2004 and 2016 (APC = -2.85). Lymph node TB cases increased (APC = 4.58), while annual number of urogenital TB decreased between 1995 and 2016 (APC = -3.38). Projected incidence rates would increase to 18.13 and 11.8/100,000 population in 2030 for global TB and EPTB, respectively. CONCLUSIONS: Our study highlighted a rise in all forms of TB and among high-risk groups, notably children, females and lymph node TB patients in the last two decades and up to the next one.
