Abstract: Background: The diagnosis of tuberculosis (TB) is frequently challenging given that the clinical and radiographic features of TB are often nonspecific. Altered leukocyte count ratios could serve as new tools of diagnostic orientation of tuberculosis. The aim of this study was to assess the diagnostic value of the leukocyte count ratios for the diagnosis of TB. Methods: This was a cross-sectional study including cases of newly diagnosed TB patients from registers of the TB treatment center of the Douala General Hospital. Control subjects were healthy volunteers, age and sex matched, recruited at the blood bank. Sociodemographic, clinical data and peripheral blood parameters were collected. The diagnostic value of leukocyte counts was determined using receiver operating characteristics curve analysis. Results: In total, 204 TB patients and 204 control subjects were included in the study. The gender of the participants was equitably distributed in the 2 study groups (male 61.8%; female 38.2%). The median age of TB patients was 33 years while that of control patients was 32 years. The monocyte-lymphocyte count ratio (MLR) and neutrophil-lymphocyte count ratio (NLR) were significantly higher in the TB patients group compared to control group. A NLR >1.19 and MLR >0.29 were identified as cut-off values for discriminating TB patients. The areas under the curves (AUC) were 0.77 and 0.84 for the MLR and NLR respectively. Conclusion: A raised NLR > 1.19 and MLR

Abstract: Los movimientos independentistas de siglo XIX en Hispanoamérica permitieron, paradójicamente, consolidar el modelo de lengua peninsular del que se habían ido alejando en las zonas no virreinales, durante los siglos de la Colonia. Ofrecemos una muestra de rasgos propios de una zona semimarginal, obtenida de fuentes documentales filológicamente editadas; rasgos que se perdieron o quedaron desplazados con la masificación y organización de la ense anza pública nacional. (The independentist movements from xix century in Hispano-America paradoxically allowed to consolidate the peninsular language model, from which zones without viceroyalty had taken distance, during the colonial years. Samples from a semimarginal zone’s features are shown, as well as those features that were lost or displaced with the spread and organization of the national public education.)

Surgical Science (SS) , 2017, DOI: 10.4236/ss.2017.88041
Abstract: Introduction: volume increase of Pediatric Surgery (PedSur) due to factors not yet fully clarified contrast with the scarcity of pediatric surgeons in Brazil and globally. Geographic distribution, surgical care costs, and graduation period might contribute to this dearth. In Brazil, vacancy occupation rate in PedSur is below 43% (162 vacancies/year). Aim: analyze the volume of procedures performed on 0 - 12 year-old patients in PedSur by a single Specialist at Hospital Regional (HR); compare with the literature and propose the outset of a PedSur Medical Residence program. Material & Method: 1912 attendances were fulfilled on 986 children who were submitted to surgical procedures between 2008 and 2012 at HR by a single specialist. Results: Surgical procedures were performed on 1137 children, an average of 227/year or 197 children per year. Surgery was carried out in 667 (68%) boys and 319 (32%) girls. Hernias, appendectomies and circumcisions were the most frequent external surgeries. 437 (44%) patients were discharged on the same day and, 549 (56%) were hospitalized. In the Pediatric ICU and in the Neonatal ICU 181 procedures were performed (18%). Conclusion: It was possible to make evident the distribution of surgeries on children, the degree of complexity and a sufficient number of subjects for training in this Specialty. The obtained data allow the development of a study with regards to the inception of a Medical Residence in PedSur at HR for training and retaining the professional in the region.

Abstract: Objective: To assess the importance of incidental extraspinal findings on Magnetic Resonance Imaging of the lumbar spine in two hospital facilities. Materials and Methods: It was a descriptive and retrospective study from November 2015 to March 2016. The records of patients who had done a Magnetic Resonance Imaging (MRI) scan of the lumbar spine were re-read in search of incidental findings. The incidental findings found were classified using Colonography Reporting and Data System(C-RADS) classification of extracolonic lesions to assess clinical significance. The prevalence of incidental findings was calculated for each facility, as well as the distribution according to age, the organs involved and the clinical importance. A non-detection rate was calculated by confronting the findings of the study with the original reports. Results: The prevalence of incidental findings was respectively 33% (19 out of 36) in Jordan Medical Center (JMC) in Yaounde and 27.74% (106 out of 292) in Jacques Monod Hospital. The extraspinal incidental findings were classified mainly as extracolonic 2 (E2): 58% in each facility. The percentage detection of incidental findings was 5% at JMS and 1.7% at Jacques Monod Hospital. Conclusion: Extraspinal incidental findings are frequent in both hospitals. However, the rate of detection remains very low.

Abstract: Background: Recent reports indicate that the use of mammography in breast screening plays a major role in reducing breast cancer-related deaths. It helps to improve quality of care and patient information. However, in Cameroon, there are no organized general breast screening programs which give women the opportunity to regularly screen their breasts, except for the few who take their own initiative for breast screening. Purpose: This study aimed to list indications and results of mammography and/or breast ultrasounds at Douala General Hospital in order to determine the proportion of routine mammographic screening. Method: This descriptive cross-sectional study was carried out at Douala General Hospital using pre-established data sheets. The study recruited all patients who met the selection criteria and reported to the radiology and medical imaging department for breast screening using physical examinations, mammography and/or ultrasounds. Results: The study recruited 372 patients, 96.8% of whom were between 40 to 50 years old. The reasons given for the medical consultation were systematic screening (33.01%); pain (27.18%) and lumps (25.24%). Breast examination by inspection was normal in 87.1% of women, and by palpation in 66.7%. Mammography revealed nodular opacities (18.3%), spiculated images (4.3%) and micro calcifications (3.2%), while ultrasound identified fibroadenomas (16.48%) and cysts (6.18%). Suspicious lesions (ACR 4 and 5) were discovered in 7.6% of cases by mammography and 8.51% of cases by ultrasound. The results indicated that there was no significant association between the use of clinical examination and mammography (p = 0.754). The use of clinical examination alone for breast screening may not be sufficient. Conclusion: Our findings indicate that in Cemaroon, the routine screening mammography accounts for less than one-third (33.1%) of all indications. Benign lesions were most common, however 7.6% and 8.51% of suspicious malignant lesions were observed using mammography and ultrasound respectively.

Abstract: Wherever measurements have been made bromoform was found to be ubiquitous in the surface ocean in pmolar-nmolar concentrations. These measurements show concentrations in coastal regions orders of magnitude higher than in the pelagic oceans. Its atmospheric presence is primarily due to its release from algae and rapid transport to the marine boundary troposphere where it is known to participate in ozone chemistry via photochemical and catalytic pathways. Until quite recently, a limited number of studies existed (compared to other marine volatile organic compounds (VOCs)), mainly due to the analytical challenge(s) presented by the low environmental mixing ratios. In this work we detail the development of a simplified, cost effective method to detect and quantify bromoform in environmental air samples. Air samples (1.5 L) were preconcentrated onto a precooled adsorbent (Carbopack X/Carboxen 1016) trap. These samples were injected by means of rapid thermal desorption for separation and detection by GC-ECD. The system was calibrated by means of a custom-built permeation oven. A linear system response was achieved, having a detection limit of 0.73 ± 0.09 ppt. A range of environmental samples was analysed to demonstrate the ability of the technique to separate and identify bromoform from air samples. The results showed that bromoform concentrations typically averaged 24.7 ± 17.3 ppt in marine air samples, 68.5 ± 26.3 ppt in Cape Town urban air samples and 33.9 ± 40.5 ppt in simulated biomass burning plumes (SBBP).
