Introduction: Pediatric Neurosurgery is a growing specialty in its own right worldwide. Its practice in sub-Saharan Africa remains confronted with many challenges, notably the absence of a pediatric neurosurgeon, the lack of a dedicated service and the absence of multidisciplinary pediatric collaboration (neuroanesthesist, neurologist, oncologist and psychotherapist). The objective of this preliminary study is to describe the practice of pediatric neurosurgery at the HSMEBG and to present perspectives for its improvement. Methods: This is a retrospective, monocentric, descriptive study covering the period from March 2021 to March 2022 at the Pediatric Surgery Department of the HSMEBG. Résults: During the study period, 50 children were hospitalized for a neurosurgical condition. The sex ratio was 1.77. The average age was 6 years with extremes of 2 weeks and 16 years. Most children were from the emergency department (46%). Computed tomography (CT) was performed in 35 patients (70%), magnetic resonance imaging (MRI) in 4% and plain radiography in two patients (8%). Malformative, traumatic (cranial and spinal) and tumor pathology were the most frequent with 42%, 36% and 12% respectively. Twenty-six patients were operated (52%). We recorded one postoperative infection (2.5%). The overall mortality was 8% (N = 4). Conclusion: This preliminary study allowed us to identify the epidemiological and clinical profile of the patients treated in our context as well as the therapeutic approach. Malformative pathology remains the most frequent, followed by traumatic and tumor pathology. The development of the practice of this discipline remains a challenge in our working conditions and requires the training of pediatric neurosurgeons and dedicated paramedical staff.

Assessement of Nutritional Status of Households Using Weighed Food Intake in North West Region of Cameroon

This study determined the nutritional status of households in North western region of Cameroon using weighed food intake. Twenty–two rural and 106 urban households were randomly selected for weighed food intake Descriptive and inferential statistics were used to analyze collected data and significance at p < 0.05 accepted. Corn fufu with huckleberry was the most frequently consumed meal with little or no animal-source protein. Protein and B group vitamins intake of respondents in both communities were below the FAO/WHO recommended values while energy, iron, and vitamins A and C were in excess for most age groups. Adolescents 10 - 19 years and adults 20 years and above failed to meet at least 85% of RNI for calcium.

Protein Expression of STAT3, pSTAT3, MMP-7 and VEGF in Colorectal Adenocarcinoma: An Immunohistochemical Study

Journal of Cancer Therapy 2014年第13期5卷 1175-1185页

Background: The purpose of the present study is to investigate the expression levels of STAT3, pSTAT3, MMP-7 and VEGF in colorectal adenocarcinoma, and also to determine association with the clinico-pathological parameters and?co-expression of these genes. Methods: An immunohistochemical method was used to evaluate the expression of MMP-7 and VEGF genes in 93 archival tissues whereas STAT3 and pSTAT3 expression was determined in 75 cases. Results: Overexpression of STAT3 was detected in 26.7% (20/75), pSTAT3 in 13.4% (10/75), MMP-7 in 38.8% (36/93) and VEGF in 59.2% (55/93) of the colorectal carcinomas. STAT3, MMP-7 and VEGF immunopositivity were significantly correlated with poorly-differentiated tumors (P = 0.004;P = 0.03;P = 0.002, respectively) but not with other parameters. However, pSTAT3 immunostaining was not significantly associated with the clinico-pathological characteristics. Significant relationship was noted between overexpression of pSTAT3 and STAT3 (P < 0.001), pSTAT3 and VEGF (P = 0.044), pSTAT3 and MMP-7 (P = 0.003), and STAT3 and VEGF (P = 0.037) but marginal association was detected between STAT3 and MMP-7 (P = 0.057), and MMP-7 and VEGF (P = 0.052). Conclusion:?Our data suggest that expression of these genes?may have an important role in tumor dedifferentiation and?may be useful as indicators of biologic aggressiveness. Co-expression of the biomarkers by cancer cells?may have important implications in colorectal cancer biology and?could be useful biological markers of the malignant phenotype.
