Background The evolution of multiple sclerosis (MS) is highly variable. Predicting this evolution at the beginning of the disease will help in the therapeutic management. The objective of this study was to describe the clinical characteristics and to identify early predictors of long-term disability among MS patients in Algeria. Methods We performed a descriptive and retrospective study of 400 MS patients followed over a 4-years period from July 2012 to July 2016 in the neurology department of Mustapha Bacha hospital in Algiers. The following parameters were systematically assessed for each patient: Age at onset, gender, relapses, initial demyelinating event, interval between first and second attack, residual deficit after first attack, onset of the progressive course, time of assignment of the successive scores of irreversible disability and type of disease modifying therapies. Univariate and multivariate Cox models were used to determine factors influencing time to Expanded Disability Status Scale (EDSS) 4 and 6. Results During the follow-up of this cohort of MS patients, a total of 144 (36%) and 83 (20%) patients reached EDSS scores 4 and 6 respectively. The median times from the onset of MS to assignment of a score 4 and 6 was 10 years and 19 years, respectively. Using the MSSS severity score, and after univariate analysis we identified several risk factors predictive of disease severity. These included male sex (P= 0.002), age of onset ≥ 40 years (P= 0.001), pyramidal (P= 0.0001), cerebellar (P= 0.002), and poly-symptomatic (P=0.0001) onset of the disease, incomplete recovery after the first attack (P= 0.0001), a high number of attacks during the first 2 years (P= 0.04) and the progressive form (P=0.001), and all these factors were correlated with a high MSSS score. However, prognostic factors in the multivariate binomial logistic regression analysis were limited to pyramidal onset, incomplete recovery after the first attack, short interval between the first and second attack, and progressive onset. Conclusion On the whole, the early predictive factors of disability in MS among Algerian patients were age of onset over 40 years, pyramidal onset, incomplete recovery after the first attack, short interval between the first and second attack and progressive form at onset. To increase the generalizability of findings, a national MS registry is strongly recommended, as well as long-term follow-up epidemiological studies.

Background and Aim Breast cancer is the second most common cause of brain metastases after lung cancer. However, the incidence of cerebral metastases from breast cancer has increased during the last years. The purpose of this study is to determine the prognostic value of chemotherapy after whole-brain radiotherapy for patients with brain metastases from breast cancer. Methods We analyzed retrospectively 63 records of patients diagnosed with brain metastases from breast cancer and treated in the radiotherapy department at the Salah Azaiz Institute of oncology over a 5-year period between 2007 and 2011. All patients received whole-brain radiotherapy. Only 4 patients had surgical resection of the metastases before radiotherapy and 36.5% of patients received systemic treatment after irradiation. Results Overall survival was 19% at 1-year and median survival was 4,5 months. Univariate analysis indicated that systemic treatment after irradiation was correlated significantly with longer survival. (p=0,046). Conclusion Determining prognostic factors might help optimize individual treatment for metastatic breast cancer. The results of our study suggest that chemotherapy is more effective on brain metastases after irradiation. This can be explained by the fragilization of the blood-brain barrier by radiation and subsequently a better passage of cytotoxic agents.

Background Traumatic brain injury is an expanding major public health problem and the leading cause of death of the young and productive part of the world’s population. Research is mainly done in high-income countries where only a small proportion of the worldwide fatalities occur. Only few studies have examined prognostic factors of traumatic brain injury outcome in developing countries including Ethiopia. This study was aimed at defining the peculiar demographic and other associated factors of traumatic brain injury (TBI) outcome among patients treated for head injury at Nekemte Referral Hospital. Objective The main purpose of this study was to describe the magnitude of TBI outcome and assess factors associated with unfavourable outcome of TBI among patients treated for head injury at the surgical side in Nekemte Referral Hospital from July 8, 2016 to July 7, 2018. Methods A retrospective cross-sectional document review was conducted among TBI patients treated for head injury from July 8, 2016 to July 7, 2018 at Nekemte Referral Hospital. Data were collected using a pre-tested data collection format. Data analysis was done using SPSS version 20. Descriptive statistics were computed and association between the dependent and independent variables were assessed by using logistic regression. Odds ratios with 95% confidence interval were computed. Significant association was declared when the p value was <0.05. Results In this study, out of 378 cases 95 (25.1%) were discharged with unfavourable outcome of which 37(9.8%) were neurologic deficits and 58 were deaths giving overall mortality rate of 15.3%. Patient age>60years (AOR: 15.13; 95%CI: 3.575-64.028), time interval from injury to treatment (AOR: 16.054; 95%CI: 5.832-44.194), low GCS (AOR: 18.224; 95%CI: 4.167, 79.695), conservative management (AOR: 20.774; 95%CI: 6.106-70.681), pupils abnormality (AOR: 9.078; 95%CI: AOR: 2.996-27.509) were associated with unfavourable outcome. Conclusions A quarter of patients treated for TBI at Nekemte Referral Hospital are discharged with unfavourable outcomes. Old age, delayed presentation to the hospital, low GCS, conservative management, and pupillary abnormality increase the odds of unfavourable outcome. Timely management of TBI before patients develop secondary brain injury and use of surgical intervention based on CT scan diagnosis will reduce the occurrence of unfavourable outcome.

Chalkley counting has been regarded as a relatively reliable method of quantifying tumor angiogenesis. In this study we investigated the reliability of Chalkley counting in quantifying tumor angiogenesis in oral tongue squamous cell carcinoma (OTSCC) using CD34; and tumor vasculogenesis using angiotensin converting enzyme, angiotensin II receptor 1 and angiotensin II receptor 2, in 32 OTSCC samples. Chalkley counting was performed by two independent observers. The averages of three ‘hot spot’ counts were compared with known prognostic factors. All four markers showed no correlation with any of the prognostic factors. When comparing the results from the two independent observers, the only marker shown to have a significant moderate correlation was CD34. The other three markers showed no significant correlation. The lack of statistical significance between the independent observers, and known prognostic factors with the four markers used, shows that Chalkley counting is not a reliable prognostic tool in OTSCC.
