Abstract
We report the synthesis and the assessment of the anticancer potential of two series of diruthenium biscyclopentadienyl carbonyl complexes. Novel dimetallacyclopentenone compounds (2-4) were obtained (45-92% yields) from the thermal reaction (PhCCPh exchange) of [Ru2Cp2(CO)(μ-CO){μ-η1:η3-C(Ph)═C(Ph)C(═O)}], 1, with alkynes HCCR [R = C5H4FeCp (Fc), 3-C6H4(Asp), 2-naphthyl; Cp = η5-C5H5, Asp = OC(O)-2-C6H4C(O)Me]. Protonation of 1-3 by HBF4 afforded the corresponding μ-alkenyl derivatives 5-7, in 40-86% yields. All products were characterized by IR and NMR spectroscopy; moreover, cyclic voltammetry (1, 2, 5, 7) and single-crystal X-ray diffraction (5, 7) analyses were performed on representative compounds. Complexes 5-7 revealed a cytotoxic activity comparable to that of cisplatin in A549 (lung adenocarcinoma), SW480 (colon adenocarcinoma), and ovarian (A2780) cancer cell lines, and 2, 5, 6, and 7 overcame cisplatin resistance in A2780cis cells. Complexes 2, 5, and 7 (but not the aspirin derivative 6) induced an increase in intracellular ROS levels. Otherwise, 6 strongly stabilizes and elongates natural DNA (from calf thymus, CT-DNA), suggesting a possible intercalation binding mode, whereas 5 is less effective in binding CT-DNA, and 7 is ineffective. This trend is reversed concerning RNA, and in particular, 7 is able to bind poly(rA)poly(rU) showing selectivity for this nucleic acid. Complexes 5-7 can interact with the albumin protein with a thermodynamic signature dominated by hydrophobic interactions. Overall, we show that organometallic species based on the Ru2Cp2(CO)x scaffold (x = 2, 3) are active against cancer cells, with different incorporated fragments influencing the interactions with nucleic acids and the production of ROS.

Abstract
Dimetallic complexes are suitable platforms for the assembly of small molecular units, and the reactivity of bridging alkenyl ligands has been widely investigated to model C-C bond forming processes. Here, we report the unusual coupling of an alkenyl ligand, bridging coordinated on a diruthenium scaffold, with a series of alkynes, revealing two possible outcomes. The diruthenium complex [Ru2Cp2(Cl)(CO)(μ-CO){μ-η1:η2-C(Ph)CH(Ph)}], 2, was prepared in two steps from [Ru2Cp2(CO)2(μ-CO){μ-η1:η2-C(Ph)CH(Ph)}]BF4, [1]BF4, in 69% yield. Then, the reaction of 2 with C2(CO2Me)2, promoted by AgCF3SO3 in dichloromethane, afforded in 51% yield the complex [Ru2Cp2(CO)2{μ-η3:η2-C(Ph)CH(Ph)C(CO2Me)C(CO2Me)}]CF3SO3, [3]CF3SO3, containing a ruthenacyclopentene-based hydrocarbyl ligand. On the other hand, 2 reacted with other alkynes and AgX salts to give the butadienyl complexes [Ru2Cp2(CO)2{μ-η3:η2-C(R)CH(R')C(Ph)C(Ph)}]X (R = R' = H, [4]BF4; R = R' = Me, [5]CF3SO3; R = R' = Ph, [6]CF3SO3; R = Ph, R' = H, [7]CF3SO3), in 42-56% yields. All products were characterized by IR and NMR spectroscopy, and by single crystal X-ray diffraction in the cases of 2, [3]CF3SO3 and [6]BF4. DFT calculations highlighted the higher stability of [4-7]+-like structures with respect to the corresponding [3]+-like isomers. It is presumable that [3]+-like isomers initially form as kinetic intermediates, then undergo H-migration which is disfavoured in the presence of carboxylato substituents on the alkyne. Such hypothesis was supported by the computational optimization of the transition states for H-migration in the cases of R = R' = H and R = R' = CO2Me.

Epidemiology and impact of frailty in patients with atrial fibrillation in Europe. Age Ageing 2022; 51:6670566. [PMID: 35997262 DOI: 10.1093/ageing/afac192] [Citation(s) in RCA: 24] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Revised: 06/08/2022] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND Frailty is a medical syndrome characterised by reduced physiological reserve and increased vulnerability to stressors. Data regarding the relationship between frailty and atrial fibrillation (AF) are still inconsistent. OBJECTIVES We aim to perform a comprehensive evaluation of frailty in a large European cohort of AF patients. METHODS A 40-item frailty index (FI) was built according to the accumulation of deficits model in the AF patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Association of baseline characteristics, clinical management, quality of life, healthcare resources use and risk of outcomes with frailty was examined. RESULTS Among 10,177 patients [mean age (standard deviation) 69.0 (11.4) years, 4,103 (40.3%) females], 6,066 (59.6%) were pre-frail and 2,172 (21.3%) were frail, whereas only 1,939 (19.1%) were considered robust. Baseline thromboembolic and bleeding risks were independently associated with increasing FI. Frail patients with AF were less likely to be treated with oral anticoagulants (OACs) (odds ratio 0.70, 95% confidence interval 0.55-0.89), especially with non-vitamin K antagonist OACs and managed with a rhythm control strategy, compared with robust patients. Increasing frailty was associated with a higher risk for all outcomes examined, with a non-linear exponential relationship. The use of OAC was associated with a lower risk of outcomes, except in patients with very/extremely high frailty. CONCLUSIONS In this large cohort of AF patients, there was a high burden of frailty, influencing clinical management and risk of adverse outcomes. The clinical benefit of OAC is maintained in patients with high frailty, but not in very high/extremely frail ones.

Course and Lethality of SARS-CoV-2 Epidemic in Nursing Homes after Vaccination in Florence, Italy. Vaccines (Basel) 2021; 9:1174. [PMID: 34696282 PMCID: PMC8537408 DOI: 10.3390/vaccines9101174] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Revised: 10/11/2021] [Accepted: 10/12/2021] [Indexed: 11/17/2022] Open
Abstract
Evidence on the effectiveness of SARS-CoV-2 vaccines in nursing home (NHs) residents is limited. We examined the impact of the BNT162b2 mRNA SARS-CoV-2 vaccine on the course of the epidemic in NHs in the Florence Health District, Italy, before and after vaccination. Moreover, we assessed survival and hospitalization by vaccination status in SARS-CoV-2-positive cases occurring during the post-vaccination period. We calculated the weekly infection rates during the pre-vaccination (1 October-26 December 2020) and post-vaccination period (27 December 2020-31 March 2021). Cox analysis was used to analyze survival by vaccination status. The study involved 3730 residents (mean age 84, 69% female). Weekly infection rates fluctuated during the pre-vaccination period (1.8%-6.5%) and dropped to zero during the post-vaccination period. Nine unvaccinated (UN), 56 partially vaccinated (PV) and 35 fully vaccinated (FV) residents tested SARS-CoV-2+ during the post-vaccination period. FV showed significantly lower hospitalization and mortality rates than PV and UV (hospitalization: FV 3%, PV 14%, UV 33%; mortality: FV 6%, PV 18%, UV 56%). The death risk was 84% and 96% lower in PV (HR 0.157, 95%CI 0.049-0.491) and FV (HR 0.037, 95%CI 0.006-0.223) versus UV. SARS-CoV-2 vaccination was followed by a marked decline in infection rates and was associated with lower morbidity and mortality among infected NH residents.

Abstract
Background Nursing home (NH) residents have been dramatically affected by COVID-19, with extremely high rates of hospitalization and mortality. Aims To describe the features and impact of an assistance model involving an intermediate care mobile medical specialist team (GIROT, Gruppo Intervento Rapido Ospedale Territorio) aimed at delivering “hospital-at-nursing home” care to NH residents with COVID-19 in Florence, Italy. Methods The GIROT activity was set-up during the first wave of the pandemic (W1, March–April 2020) and became a structured healthcare model during the second (W2, October 2020–January 2021). The activity involved (1) infection transmission control among NHs residents and staff, (2) comprehensive geriatric assessment including prognostication and geriatric syndromes management, (3) on-site diagnostic assessment and protocol-based treatment of COVID-19, (4) supply of nursing personnel to understaffed NHs. To estimate the impact of the GIROT intervention, we reported hospitalization and infection lethality rates recorded in SARS-CoV-2-positive NH residents during W1 and W2. Results The GIROT activity involved 21 NHs (1159 residents) and 43 NHs (2448 residents) during W1 and W2, respectively. The percentage of infected residents was higher in W2 than in W1 (64.5% vs. 38.8%), while both hospitalization and lethality rates significantly decreased in W2 compared to W1 (10.1% vs 58.2% and 23.4% vs 31.1%, respectively). Discussion Potentiating on-site care in the NHs paralleled a decrease of hospital admissions with no increase of lethality. Conclusions An innovative “hospital-at-nursing home” patient-centred care model based on comprehensive geriatric assessment may provide a valuable contribution in fighting COVID-19 in NH residents.

Abstract
Heart failure (HF) and atrial fibrillation (AF) often coexist. Subjects with permanent AF show the highest prevalence of HF. Patients with incident AF have HF in a great number of cases and, reciprocally, in patients with incident HF, an AF can be frequently found. The simultaneous presence of the two conditions is associated with mortality rates higher than those observed in individuals with only one or none of them. Interestingly, HF and AF could synergistically promote in elderly patients the development of disability and dementia. Inflammatory mechanisms coupled with changes of renin-angiotensin system, hormonal pathways and neuro-mediators could simultaneously promote left atrium remodeling and sustain both HF and AF. Beta-blockers and digoxin seem to have small therapeutic effect and limited influence on prognosis in these very complex patients. Sinus rhythm restoration could slow down the progression of disability in symptomatic subjects. Recent evidence seem to suggest that upstream therapy coupled with rehabilitation, and that AV node ablation associated with cardiac resynchronization therapy could benefit subjects with HF and AF. In conclusion, elderly patients simultaneously presenting problems of cardiac function and arrhythmia are an important challenge for geriatric medicine, and request important efforts to improve their functional profile and prognosis.

Abstract
INTRODUCTION Dry eye disease (DED) can be evaluated clinically by the tear film break up time (BUT). There is a discrepancy between symptoms in relationship with dry eye disease and objectives measures of BUT. So we tried to evaluate the reliability of BUT in the diagnosis and treatment of this disease in black African people. METHODS We carried out a prospective study of 6 months where melanoderms adults presenting subjective symptoms of dry eye disease according a questionnaire of 7 items were included. Then the measure of BUT is performed after ocular instillation of fluorescein eyedrop. This measured is done by recording the time elapsed from the last complete palpebral blink to the appearance of the first dry spot. Patients with subjective symptoms and time of BUT lower than 10seconds were called concordants (suffering really of DED). The discrepant group was represented by a BUT upper than 10seconds despite the fact that these patients answered positively to the questionnaire. RESULTS This survey included 234 patients and the average age was 49.1 years. Sex-ratio was 0.68 and we noticed predominance of BUT between 5 and 10seconds in 42.3% of cases. Subjective symptoms were strengthened clinically by a BUT lower to 10seconds in 149 patients. Therefore, the reliability of BUT as clinic tool for the diagnosis after symptoms in relationship with DED was 63.7%. In the group of concordants, women were more likely than men to experience symptoms of DED (P=0.0005). Age upper than 50 years and computer usage were risk factors of DED (P<0.01). DISCUSSION Dry eye disease is a multifactorial affection of tear and ocular surface frequently seen in female and people using computer and older than 50. The reliability of BUT near to 65% is a reason to perform this test in our daily practice. CONCLUSION Tear BUT is a reliable clinical test which must be performed systematically to assess the diagnosis of DED in black African people.

Abstract
Aims Diabetes mellitus (DM) is one of the most important cardiovascular risk factors. The aim of this study was to evaluate clinical correlates of DM, including management and outcomes, in the EURObservational Research Programme (EORP)-Atrial Fibrillation (AF) General Pilot (EORP-AF) Registry of the European Society of Cardiology. Methods and results We studied consecutive patients (N = 3101) enrolled in 70 centres of nine European countries between February 2012 and March 2013, and compared diabetics with non-diabetics during a 1-year follow-up. In the overall cohort, the prevalence of DM was 20.6%. Diabetics were older (71 ± 9 vs. 68 ± 12 years, P < 0.0001) and had more comorbidities, higher CHA2DS2-VASc score (4.6 ± 1.6 vs. 2.9 ± 1.7, P < 0.0001) and higher prevalence of permanent AF (21.5 vs. 16.0%, P = 0.0022). Quality of life amongst DM patients was significantly worse [atrial fibrillation quality of life questionnaire (AF-QoL) score 45.2 ± 19.2 vs. 49.3 ± 20.1, P < 0.0001]. Amongst diabetics, the use of electrical cardioversion (16.2 vs. 24.6%, P < 0.0001) and catheter ablation (3.3 vs. 8.6%, P < 0.0001) was lower, whilst oral anticoagulants were more often prescribed (84.3 vs. 78.9%, P = 0.0027). After one year, diabetic patients had significantly higher all-cause (11.9 vs. 4.9%, P < 0.0001), cardiovascular (6.2 vs. 1.9%, P < 0.0001), and non-cardiovascular mortality (2.3 vs. 1.1%, P = 0.0356). Conclusion In AF patients, DM is associated with a higher prevalence of comorbidities and a worse quality of life. After one year, all-cause, cardiovascular, and non-cardiovascular mortality were significantly higher in diabetic subjects.

Abstract
Aims: To report the experience of surgical caravans for urogenital fistulas care.
Methods: It was a retrospective study covering the period from January 1st 2014 to December 31st 2014 and which took place on 7 sites of fistula care. The epidemiological, anatomic, clinical, therapeutic and evolutionary aspects were studied. Recruitment was made by radio announcements and word of mouth approaches. Treatment was free of charge for patients.
Results: During 14 caravans 346 patients were operated. Their mean age was 33.11 years (12 - 70 years). Most of these patients were without remunerative activities (80%) and without education (63.3%). They had been living with fistula for 6.08 years on average (0 to 42). Obstetrical etiology was predominant (87.9%), the otherswere iatrogenic and traumatic. According to the Kees Waaldijk classification, fistulas were distributed as follows: type I (67.4%), type II Aa (12.7%), type II Ab (8.4%) and type III (11.5%). The most common surgical approach was the transvaginal route (82.1%). The vesicovaginal splitting with separated suture of the bladder and the vagina was the basic technique (94.7%). The therapeutic results were judged after a follow-up of 1 month and 3 months. Lost to follow-up within that period was 23% i.e. 80 patients in month one and 70% (245 patients) at month three. The success rates evaluated in patients reviewed at month one and at month 3 were respectively 70% and 64%.
Conclusions: Caravan approach to recruit patients with fistula was feasible using local advertisements mans. Patients have been living with fistula for long time. Follow-up was difficult at Month 3.

Abstract
Atrial fibrillation (AF) is the most frequent arrhythmia in elderly people. Findings derived from clinical trials seem to demonstrate that a rate-control strategy of AF in aged patients improves prognosis if compared to a rhythm-control one. However, epidemiological studies concordantly show that the arrhythmia is associated to increased hospitalization and mortality rates. In last years, the proportion of patients admitted to hospital for AF has progressively increased; this trend is observed in subjects >75 and >85 years, while no change was found in younger cohorts. Importantly, in aged individuals, probably because of the loss of atrial activity, the increase of heart rate and the irregularity of RR intervals, AF begins a vicious cycle, leading from heart failure, through the compromise of functional and neurocognitive status, to overt disability, dementia and increased mortality. Evidence specifically aimed at clarifying the effects of arrhythmia management on outcomes characteristic of aged people is completely lacking. In the elderly, the question regarding the effects of a rate- or a rhythm-control strategy of AF should be considered as an aspect of a more complex strategy, addressed to reduce disability and hospitalizations, and to improve quality of life and survival.

Abstract
BACKGROUND Given the importance of monitoring healthcare-associated infections (HCAIs) and the consumption of antibiotics, a regional point prevalence survey was conducted in Liguria between March and April 2016. AIM To measure the overall prevalence of HCAI and describe the use of antibiotics in all public hospitals. METHODS Data on risk factors and use of antibiotics were collected for each hospitalized patient. To define the variables significantly associated with HCAI, univariate and multivariate analyses were conducted. Standardized infection ratio and standardized antimicrobial use ratio were measured for each participating hospital. FINDINGS A total of 3647 patients were enrolled. In all, 429 HCAIs were diagnosed in 376 patients, giving a prevalence of HCAI of 10.3%. Respiratory tract (21.7%) and urinary tract (20%) were the most frequent sites of infection. High rates of meticillin-resistant Staphylococcus aureus (47.4%) and Enterobacteriaceae resistant to carbapenems (26.3%) were isolated. Forty-six percent of patients received at least one antibiotic. Combinations of penicillins including β-lactamase inhibitors (24.1%) were the most widely used; the main indication (46.7%) was the treatment of a community-acquired infection. CONCLUSION There was an increase in HCAI prevalence compared to a similar survey conducted in 2007; however, the performance of overlapping investigations will enable more reliable considerations. Nevertheless, data on antimicrobial resistance and use of antibiotics are consistent with the national trend. Despite methodological limitations, prevalence studies are useful to monitor HCAI over time and encourage greater awareness of the problem by all stakeholders.

Abstract
BACKGROUND Novel devices based on the emission of near-infrared electromagnetic radiation (NIR) have been developed to minimize venous puncture failures. These instruments produce an "augmented reality" image, in which subcutaneous veins are depicted on a LCD display. We compared the new technique with standard venipuncture in a population of elderly patients. METHODS Patients admitted in Intensive Care Unit were randomized to standard or to NIR assisted procedure. RESULTS In the 103 enrolled patients (age 74 ± 12 years; standard venipuncture-N = 56; NIR-N = 47), no differences were found in procedure length, number of attempts, and referred pain. With NIR there was a lower incidence of hematomas and fewer anxiety and depressive symptoms. CONCLUSIONS The use of the novel NIR-based device is safer and more psychologically tolerable, and it is not associated to an increase of procedure length or number of attempts.

Abstract
INTRODUCTION The invasive fungal infection of the maxillary sinus is a rare and serious disease generally favored by immunosuppression. We report an exceptional case of pseudotumoral invasive fungal infection of the maxillary sinus in an immunocompetent patient. OBSERVATION A 32-year-old patient consulted for labial and left temporal swelling associated with proptosis and chemosis that has been developing for 18 months. The scanner objectified a filling of the left maxillary sinus, and the ipsilateral orbital cavity, and the surrounding muscles. Histological examination of the surgical specimen revealed invasive fungal infection of the left maxillary sinus. The relevant antifungal therapy, namely voriconazole, could not be administered due to the unavailability of the medicine. However, the patient has received 200mg of itraconazole every 12hours for three weeks. The change proved disappointing with recurrence and significant sequelae, sort of sagging of the right hemifacial, severe limitation of mouth opening and functional loss of the right eye. CONCLUSION The invasive fungus infections of the maxillary sinus and the orbit are exceptional in immunocompetent patient. Healing is based on early diagnosis and administration of the reference antifungal to face the risk of recurrence.

Abstract
La diagnosi di instabilità del rachide lombo-sacrale è, a tutt'oggi, fondamentalmente clinica. Anche le più sofisticate tecniche di diagnostica radiologica consentono infatti solo una valutazione statica di questa entità nosologica (che, per definizione si manifesta durante la deambulazione e con la stazione eretta) la cui definizione dinamica è campo pressochè esclusivo della radiologia convenzionale. Presentiamo i risultati di uno studio condotto attraverso l'uso di uno strumento originale progettato per sviluppare un carico assiale variabile e riproducibile in un paziente supino: il Compressore assiale. Con questo strumento, compatibile con l'esecuzione di esami TC, sono stati valutati 24 pazienti con forte sospetto clinico-radiologico di instabilità lombare. La metodica di studio, denominata Axial Loaded - Computed Tomography (AL-CT) si basa sull'acquisizione successiva di esami TC basali e con carico assiale (AL), che vengono poi comparati. Il confronto avviene sia sulle scansioni assiali che su immagini ricostruite su piani sagittali e con «rendering» tridimensionale (3D-TC). La valutazione comparativa prevede sia l'uso di immagini statiche che l'organizzazione in sequenze cine (cine AL-CT) delle immagini 2D e 3D ottenute. Tutti i procedimenti di rielaborazione sono indispensabili nella valutazione dei risultati. I risultati mostrano con chiarezza reperti (numerosi e spesso simultanei) a carico di tutte le component le unità funzionali spinali; fra questi meritano una segnalazione: l'incremento o la accentuazione di protrusioni discali sotto carico; la scomparsa del vacuum discale e/o intraarticolare durante la compressione («segno del vacuum»); l'accentuazione della listesi sotto carico; la ottimale ed originale visualizzazione dell' ipermobilità delle faccette articolari. Proponiamo AL-CT e cine AL-CT come metodiche di scelta nello studio dell'instabilità lombare.

Abstract
È stata valutata l'utilità diagnostica del rendering tridimensionale di esami TC (3D-TC) nelle malformazioni artero-venose e negli aneurismi del poligono di Willis. Particolare attenzione è stata posta sulla scelta dei valori di soglia di campionamento delle tessere, da cui dipendono sia la qualità che il significato diagnostico dell'imagine 3D ottenuta. Il rendering 3D concentra in poche immagini significative una considerevole quantità di informazioni con passaggio di un elevato flusso informativo dal radiologo al clinico. In particolari situazioni di diagnostica differenziale la scelta di corretti valori di soglia («segno dell a soglia») può fornire informazioni diagnostiche originali.

Abstract
We present the case of an elderly woman which demonstrates how AF therapy in aged individuals is particularly challenging for the presence of complex conditions. The rhythm- or the rate control strategy must be carefully chosen based on individual risk profile. Oral anticoagulant therapy must be wisely managed to maximize benefits-in terms of stroke and dementia control-and to reduce complications.

Abstract
BACKGROUND AND AIMS Atrial fibrillation (AF) is the most common arrhythmia in elderly people, yet oral anticoagulation is underused in the aged. We tried to determine whether new oral anticoagulants (NOA) have greater psychological tolerability than warfarin. METHODS Age-, gender-matched groups of AF patients receiving NOA (N = 15) or warfarin (N = 15) were assessed with the Anti-Clot Treatment Scale (ACTS) and the Perceived Stress Scale (PSS). RESULTS Patients were old (81 ± 9 years). NOA group showed greater psychological satisfaction, with lower therapy-related burden (ACTS burdens: 16.3 ± 4.5 vs. 32.9 ± 10.2, p < 0.001) and higher awareness of benefits (ACTS benefits: 13.0 ± 1.3 vs. 10.8 ± 1.9, p = 0.001). Even stress was lower (PSS: 13.1 ± 4.0 vs. 17.1 ± 4.2, p = 0.013). The multivariate analysis confirmed these findings, showing that higher levels of anxiety and depression could justify more stress in warfarin patients. CONCLUSIONS The results of this preliminary study show that NOA have an improved psychological impact compared with warfarin in elderly patients.

Abstract
The authors report a case of Kaposi's sarcoma (KS) found in a pregnant woman. On discovery, the condition had spread throughout her body as is characteristic in some cases of individuals with HIV-positive serology. She was unaware of her HIV positive status. Her HIV infection had been diagnosed at the same time as KS at her last prenatal consultation. The newborn was delivered by an uncomplicated cesarean section. Appropriate treatment and multidisciplinary management after childbirth resulted in complete remission.

Abstract
A multi-mycotoxin method based on liquid chromatography/tandem mass spectrometry (LC-MS/MS) was used for a mycotoxin survey in 627 samples of processed cassava collected from different districts across Tanzania and Rwanda after the method performance for this matrix had been determined. Matrix effects as well as extraction efficiencies were found to be similar to most other previously investigated matrices with the exception of distinct matrix effects in the negative ionisation mode for early eluting compounds. Limits of detection were far below the regulatory limits set in the European Union for other types of commodities. Relative standard deviations were generally lower than 10% as determined by replicates spiked on two concentration levels. The sample-to-sample variation of the apparent recoveries was determined for 15 individually spiked samples during three different analytical sequences. The related standard deviation was found to be lower than 15% for most of the investigated compounds, thus confirming the applicability of the method for quantitative analysis. The occurrence of regulated mycotoxins was lower than 10% (with the exception of zearalenone) and the related limits were exceeded only in few samples, which suggests that cassava is a comparatively safe commodity as regards mycotoxins. The most prevalent fungal metabolites were emodin, kojic acid, beauvericin, tryptophol, 3-nitropropionic acid, equisetin, alternariol methylether, monocerin, brevianamide F, tenuazonic acid, zearalenone, chrysophanol, monilifomin, enniatins, apicidin and macrosporin. The related concentrations exceeded 1 mg kg(-1) only in few cases. However, extremely high levels of cyanogenic plant toxins, which had been previously added to the method, were observed in few samples, pointing out the need for improved post-harvest management to decrease the levels of these compounds.

Abstract
BACKGROUND AND AIMS Atrial fibrillation (AF) is the most frequent arrhythmia in elderly patients. Aims of this study were to evaluate the predictors of arterial stiffness after external cardioversion (ECV) of AF and to establish whether a link exists between vascular properties and left atrial diameter (LAD). METHODS We studied 33 patients (age 73 ± 12 years). After 5 h from ECV of persistent AF, an echocardiogram was recorded and arterial stiffness was evaluated with cardio-ankle vascular stiffness index (CAVI). RESULTS In multivariate analysis (R = 0.538, p = 0.006), CAVI (mean 9.60 ± 1.63) increased with age (p = 0.018) and with an AF length ≤3 months (p = 0.022). LAD was significantly related to CAVI (p = 0.007) even after adjustment for interventricular septum thickness (p = 0.018) (R = 0.574, p = 0.002). CONCLUSIONS In patients with AF, immediately after ECV, arterial stiffness is associated with age and AF length, and could represent an important factor for left atrium remodeling and, therefore, for AF maintenance.

Abstract
INTRODUCTION Cataract induced by corticosteroids is an entity, which has been well described for a relatively long time, but this eventuality caused by the cutaneous application of corticosteroids remains inadequately reported. The purpose of this study was to describe cataract as one of the complications of the misuse of cutaneous application of corticosteroids. MATERIALS AND METHODS In eight patients seen for visual loss, bilateral cataract was discovered. The only probable etiology in these cases appeared to be the cutaneous application of corticosteroids. Indeed, the work-up and careful history performed did not uncover any other etiology. RESULTS Eight patients, six women and two men, exhibited cataracts related to the application of topical corticosteroids. The age of the patients ranged between 39 and 45 years. The cataracts were bilateral and posterior subcapsular alone or combined. The period of use of corticosteroids ranged from 5 to 10 years. The products used consisted of a variety of chemicals including corticosteroids mainly in the form of traditionally manufactured soap, but also as ointment or other types of mixtures. CONCLUSION Topical corticosteroids induce posterior subcapsular cataract. The mechanism of action is direct access to the eye without any hepatic-first pass effect on the corticosteroid in question. The increasingly frequent use of corticosteroids in African blacks for skin lightening raises concern regarding the risk of epidemic cataracts in young women attempting to lighten their skin to be beautiful. Increased public awareness should be undertaken to prevent this growing and harmful phenomenon.

Abstract
Amniotic band syndrome (ABS) is a fetal congenital malformation, affecting mainly the limbs, but also the craniofacial area and internal organs. Two mains pathogenic mechanisms are proposed in its genesis. Firstly the early amnion rupture (exogenous theory) leading to fibrous bands, which wrap up the fetal body; secondly, the endogenous theory privileges vascular origin, mesoblastic strings not being a causal agent. The authors believe that the second theory explain the occurrence of ABS. The outcome of the disease during pregnancy depends on the gravity of the malformations. Interruption of the pregnancy is usually proposed when diagnosis of severe craniofacial and visceral abnormalities is confirmed. Whereas minor limb defects can be repaired with postnatal surgery. In case of an isolated amniotic band with a constricted limb, in utero lysis of the band can be considered to avoid a natural amputation. In an African country, such treatment is not possible as far as the antenatal diagnosis.

Abstract
Vulvar cancers are uncommon, represented in 90% of cases by squamous cell carcinoma (SCC). The reduction of the frequency and the severity proceed by recognition of precancerous or beginning lesions. They occur most often in the third age in postmenopausal women. The diagnosis is almost difficult and often late and therefore prognosis is severe. Conditions for diagnosis and treatment are difficult in underdeveloped countries due to the inaccessibility of proper equipment in the healthcare system. The authors report a case of SCC diagnosed late in a young human immunodeficiency virus (HIV) women who have been treated with neoadjuvant chemotherapy and radical surgery of the vulva.

BACKGROUND The surgery of the idiopathic epimacular membrane has gained from the advent of 25-gauge transconjunctival vitrectomy (TSV) initiated by Fujii in 2002. PATIENTS AND METHODS In this retrospective study, we tested 50 patients operated on for epimacular membrane with 25-gauge TSV at the Quinze-Vingts National Ophthalmology Hospital in Paris from December 2004 to June 2006. RESULTS No postoperative endophthalmitis, major hypotonia, or sclerotomy leakage were observed. However, two cases (4%) of retinal detachment and 47% postoperative cataract were noted at 3 months. After evolving 3 months later, distant and close visual acuity were significantly improved. CONCLUSION TSV appears to be a useful method for epimacular membrane ablation.

Abstract
OBJECTIVES The aim of this study was to improve the medical assistance and the prognostic of cervical cancer in African society. MATERIALS AND METHODS It was a retrospective and descriptive study carried out in the gynecology and obstetrics department at the teaching hospital of Cocody. It spanned over five years, from January 1st, 2002 to December 31st, 2006. It was focused on 171 cases of cervical cancer histologically confirmed. RESULTS The frequency of cervical cancer in that study was 1.7%. Patients had an average age of 48.5 years. 38.7% of patients were aged between 41 and 50. Multiparous represented 73.1% of patient with a majority of 38.6% for seven births and more. Patient socio-economic background was low in 72% of cases, married and divorced patients represented 63.2%. Patients who had an early sex and those with numerous partners respectively represented 77.2% and 73.2%. In 70.2% of cases, they had suffered a sexually transmitted infection once. Extension rate was limited to the financial capacities of our patients. Operable stages represented 19.3% and belated stages 57.1%. Only 8.8% of our patients were operated. The average theoretical cost of the surgical treatment was 298.203 F CFA. CONCLUSION This study showed that to improve medical assistance to patients, it is (capital) urgent to face efficiently the out break of factors of risk and improve diagnosis and therapy.

Abstract
INTRODUCTION In Africa, in spite of systematical practice of echography, Placenta praevia (PP) remains a high risky gravid complication, very unpredictable, with a high lethality rate. OBJECTIVES The aim of our study was to reconsider the frequency of this pathology, to appreciate the maternal and fetal prognosis. PATIENTS AND METHODS This was a retrospective cohort study, about 340 cases of PP, at the University Hospital of Cocody in Abidjan, during 5 years, from January 1st 2002 to December 31st 2006. We included in this study all the parturients with a gestational age > or = 28 weeks of amenorrhea, and a PP diagnosed during either pregnancy, or labour, or after placenta stage. Maternal age, parity, gynecologic and obstetrical antecedents, mode of delivery and maternal and fetal prognosis was compared between patients with PP and a group of witness chosen among normal pregnancies. The comparison has been done by using X² and Fischer test with a threshold of signification of 5%. RESULTS The frequency of PP in our study was 1.6%. The maternal age was > or = 30 years old for 43.2% of patients with PP against 28% in witness group (p=0.000). Among cases of PP, multiparous and high multiparous represented 37.7% against 10% in the witness group. Healing uterus was an increasing factor of PP (32 cases against 8 in witness group; p=0.024). Caesarean operation has been the principal mode of delivery among the patients with PP (80%). 43.8% of newborn was premature against 8.5% in the witness group (p=0.0000). The perinatal mortality was 21.3% in cases of PP against 3.8% in witness group. Three maternal deaths (0.9%) have been noticed among patients with PP. CONCLUSION The management of PP is still badly definite in Africa. The early diagnostic by ultrasound examination permit an adapted supervision and the prevention of all obstetrical complications of this pathology.

Abstract
OBJECTIVE This study aimed to show that central serous chorioretinopathy is present in Ivory Coast and that the emotional and psychosocial context plays an important role in this disorder's pathogenesis. PATIENTS AND METHOD The authors report six central serous chorioretinopathy cases based on angiographic diagnosis, five in Black African subjects and one in a European subject. These cases were observed over a period of 2 years during the Ivorian political-military crisis. RESULTS In a center where angiography has been a current practice since 1999, up to 2002 479 angiographies were done without a single central serous chorioretinopathy case being diagnosed. After the beginning of the political-military crisis, six cases of central serous chorioretinopathy were observed out of 417 angiographies over a period of 2 years. All the patients were males, between 20 and 50 years old, five were Black Africans and one was a white European. Their professions varied (a contractor, a soldier, a business executive, for example). The angiography showed break points in ink spots in the majority of the cases, with one case showing multiple break points. All the patients were emotionally distraught because of the uncertainty of the political situation. CONCLUSION This study confirms that central serous chorioretinopathy does indeed exist in the Black African subject, as it exists in the leucoderma subject without discrimination. This study emphasizes the anxiety and extreme emotional context as an initiating factor in the occurrence of central serous chorioretinopathy.

Abstract
The authors analyzed the post operative results of the penetrating keratoplasty after removal suture in Ophthalmology Service of University and Hospital's Center in Tours. The age of patients varied 20 to 90 years with an average of 56,83 years. 41,71% of patients had a pseudophakic or aphakic bullous keratopathy. Ocular hypertony was the most frequently post operative complication (63,67%). Final removal's suture improved the transparency of grafts and so the visual acuity in spite of greater endothelial cell loss (65,65%) and residual corneal oedema.
