The impact of partial termination of food subsidy programme on food consumption pattern.

The aim of this study was to evaluate the public opinion towards the possible replacement of ration cards by cash payment and to investigate the effect of partial termination of food price subsidy programme on food consumption by families from different income brackets. A purposive sample of 300 families from Alexandria Governorates were interviewed to assess the attitude of the consumer towards the possible termination of current food subsidy programme. After one year, during which the subsidy programme was reduced, a follow up sample of 240 were interviewed. The results show that a large proportion of the families prefer the continuation of the current programme (80-81.2%), meanwhile, around 90% of them believed that subsidized foods do not reach the target group. The data show that subsidized meat and poultry are consumed by high income families while frozen subsidized fish was mostly consumed by poor families. The partial termination of the subsidy programme forced the families to reduce their consumption from sugar, tea, oil, and rice. During the second phase of the study. However the results show that high income families were least affected by the partial termination of the subsidy programme.     

L'atteinte du pied au cours du rhumatisme psoriasique. À propos de 26 cas

Objective. – To describe the clinical and radiological features of foot involvement in patients with psoriatic arthritis.Methods. – We retrospectively reviewed the medical records of patients admitted between 1972 and 1999 for psoriatic arthritis with involvement of the foot. We included all patients who had peripheral and/or axial, asymmetric, chronic inflammatory joint disease meeting or not Avila's radiological criteria for psoriatic arthritis, with or without other imaging findings suggestive of psoriatic arthritis and with or without psoriasis.Results. – Twenty-six patients were included. Inflammatory heel pain was reported by 14 patients, whereas forefoot involvement was found in only seven patients. Sausage toe was present in two patients. None of the patients had Bauer's toe (combining arthritis and psoriatic skin and/or nail changes) or psoriatic onychopachydermoperiostitis of the great toe. Radiological abnormalities were found in 20 patients. Half the patients had calcaneal changes. Osteoperiostitis of the great toe was noted in two patients and mushrooming in five.Discussion. – The features of psoriatic arthritis in Morocco seem similar to those in other countries. Hindfoot involvement was present in 53% of patients. Involvement of the forefoot was rarely recorded in the charts, suggesting missed cases because of insufficient attention to the forefoot during the physical examination and availability of anteroposterior radiographs only. Oblique views (Hirtz and Chaumet) should be obtained because they give a clearer image of the distal part of the toes, which is often difficult to analyze on anteroposterior films.     

Analysis of the four heart sounds statistical study and spectro-temporal characteristics

Abstract

Heart auscultation has been recognised for a long time as an important tool for the diagnosis of heart disease; it is the most common and widely recommended method to screen for structural abnormalities of the cardiovascular system. Detecting relevant characteristics and forming a diagnosis based on the sounds heard through a stethoscope, however, is a skill that can take years to be acquired and refine. The efficiency and accuracy of diagnosis based on heart sound auscultation can be improved considerably by using digital signal processing techniques to analyse phonocardiographic (PCG) signals. The study of the functioning of the heart is very important for the diagnosis of different cardiac pathologies. The phonocardiogram signal (PCG) is the signal generated after conversion of the sound noises coming from the heart into an electrical signal, it groups together a set of four cardiac noises (S1, S2, S3, S4) which are in direct correlation with cardiac activity. The short-term Fourier Transform (STFT) is an analytical technique that describes the evolution of the time and frequency behaviour of these four heart sounds. A statistical study has been carried out in this direction in order to better highlight the characteristics of the PCG signal. A fairly high number of cycles (twenty) was used to further refine the expected results. The objective of this paper is to use a statistical analysis based on the results obtained by the use of The STFT technic this in order to find statistical parameters (mean, standard deviation, etc.) which can give us a clear vision of the electrophysiological behaviour of the phonocardiogram signal. This aspect has not been done so far and which however can give appreciable practical results.     

Daily versus thrice-weekly interferon alfa-2b plus ribavirin for the treatment of chronic hepatitis C in HIV-infected persons: a multicenter randomized controlled trial

Among HIV-infected persons, chronic hepatitis C virus (HCV) infection causes substantial morbidity and mortality. However, few studies have evaluated the safety and efficacy of interferon alfa (IFN) and ribavirin (RBV) therapy in co-infected persons. Accordingly, a randomized, controlled, open-label, multicenter trial was conducted to establish the safety, tolerability, and efficacy of IFN alfa-2b 3 mIU daily plus RBV 800 mg/d compared with IFN alfa-2b 3 mIU thrice weekly (TIW) plus RBV 800 mg/d in HCV treatment-naive, HIV-infected subjects with compensated liver disease and stable HIV disease. The primary endpoint was sustained virologic response (SVR), defined as an undetectable HCV RNA level 24 weeks after discontinuation of HCV therapy. At study entry, subjects in both groups were similar with respect to age, gender, HCV genotype, and HIV disease status. Of 180 randomized subjects, 162 received at least 1 dose of study medication, constituting the modified intention-to-treat population. After 12 weeks of therapy, 122 (75%) had serum HCV RNA levels assessed; of these subjects, early virologic response (undetectable HCV RNA or >2 log10 decrease from baseline) was observed in 33 (42%) and 13 (16%) of subjects taking daily and TIW IFN, respectively (P < 0.001). SVR was observed in 15 (19.0%) and 7 (8.4%) of subjects taking daily and TIW IFN, respectively (P = 0.05). Adverse events were similar in both groups. However, while no deaths or opportunistic infections were observed, nearly 30% of subjects stopped treatment due to adverse events and 7 subjects experienced a serious adverse event. In conclusion, SVR was achieved in 19% of HIV/HCV coinfected subjects treated with daily IFN plus RBV, but the effectiveness of therapy was substantially diminished by relatively high rates of treatment-related toxicity.     

Laparoscopic surgery for obesity

Bariatrics surgery has been a subject to a noteworthy revolution since the advent of the laparoscopic approach. This overview of the literature highlights on established scientific data in this field and the eventual evidence bases of laparoscopic surgery. Vertical banded gastroplasty and gastric bypass are now recognised as the gold-standards for the surgical treatment of morbid obesity by laparotomy. For the minimally invasive approach, the gastric banding appears now as a validated technique with a good level of evidence. The results of this approach appears to be comparable to those of other techniques (in terms of weight loss). But there is at present no randomized trial comparing the gastric banding with the gold-standards (gastric banding versus vertical banded gastroplasty). Some particular feature of this surgery are discussed (such as the association of a gastroesophageal reflux disease or a cholelithiasis). The criteria of patient's selection, the pre and post-operative management are also detailed in the light of literature data and guidelines of international societies.
