Introduction: Dermatopathology is a fundamental complementary examination for the diagnosis of certain skin conditions when the clinic is hesitant. We therefore initiated this work in order to determine the contribution of dermatopathology in the diagnostic management of certain dermatoses at the Treichville University Hospital Centre of Abidjan. Material and methods: This is a cross-sectional descriptive study with data collection from medical records in the dermatology-venereology and pathological anatomy departments of the Treichville University Hospital Centre. Results: We included and analyzed 184 patients with a sex ratio of 1.2. 46.2% of lesions were generalized with 2% mucosal localization. Erythematosquamous lesions (24.45%) and papules (22.82%) were the most biopsied lesions. The single biopsy sample accounted for 71.2% of the cases and the lesion size ranged from 0.5 cm to 10 cm. Biopsy parts of the lesion alone accounted for 65.2% versus 34.8% for those straddling healthy skin and lesion. Histological diagnosis was established in 91.3%. Kaposi disease accounted for 14.9% of cases followed by psoriasis 11.3%. In the case of three diagnostic hypotheses, the concordance was 84.8%. It was 76.6% for two hypotheses mentioned and 52.3% for a single hypothesis. Conclusion: This work shows that in more than half of the cases, the clinical hypotheses and the histological diagnosis match. It suggests however to continue the training of dermatologists to improve the skin biopsies and invites to initiate clinicopathological confrontations to better refine the diagnoses.

Introduction: The greatest effect of maternal mortality is renowned in children aged 2 - 5 months whose mothers had died. Children whose mothers died due to maternal complications were likely to record a higher mortality in infancy compared to children of surviving mothers. Motherless children mostly suffer a lot due to lack of day-to-day care, isolation, lack of motivation as well as economic cost associated with mother’s death. Thus, the purpose of this study was to ascertain the lives of children whose mothers passed away during childbirth at the Sagnarigu Municipality. Methods: This quantitative cross-sectional study was carried out at the Sagnarigu Municipal. The study recruited 297 respondents. To assess the effects of maternal death on the lives of children, families that experienced maternal death were assessed. The number of pregnancies experienced by the deceased woman, pregnancy-related complaints experienced, determinants of maternal death, number of children alive, and their standard of living were assessed with the aid of a structured questionnaire. Results: The data showed that negligence, illiteracy, poor road access, poverty, ignorance, delays in recognizing the problem, delays in making appropriate decisions, delays in the health facility, delays in giving the appropriate treatments, and traditional beliefs were some of the factors that led to maternal death in the Sagnarigu Municipality. Conclusion: The study concluded that determinants of maternal death in the Sagnarigu Municipal included the following;negligence, illiteracy, poverty, and delays in recognizing the problem. The study findings also demonstrated that the effects of maternal death on children are diverse and cut across different areas of a child’s life including livelihood sustenance, healthcare, education, and emotional and psychological development.

Background: In Sub-Saharan Africa, pre-eclampsia remains a major health problem contributing to high rates of maternal mortality. Despite this condition having adverse effects on maternal and child health, its prevalence and associated risk factors are still significant, especially in developing countries including Ghana. This study aimed to assess the prevalence and demographic distributions associated with pre-eclampsia among pregnant women at the Ho Teaching Hospital. Methods: A facility-based retrospective study was conducted by reviewing available data or hospital records of pregnant mothers admitted to the labor and maternity wards from January 2018 to December 2020. All pregnant women who were diagnosed with pre-eclampsia within this period were included in the study. The data were collected using a structured checklist. Results: 5609 data on pregnant women from 2018 to 2020 were recorded. Out of the 5609 data recorded, 314 pre-eclampsia cases were recorded giving an overall prevalence of 5.6%. The yearly prevalence for 2018, 2019, and 2020 were 4.6%, 5.6%, and 6.6%, respectively. The most recorded pre-eclampsia cases were seen among women within the age group of 18 - 24 years. The data showed that 112 (35.7%) of the pregnant women who had pre-eclampsia were nulliparous. Pre-eclampsia-associated maternal and fetal complications were;preterm delivery 221 (70.4%), intrauterine fetal death 62 (19.7%), eclampsia 9 (2.9%), HELLP syndrome 5 (1.6%) and maternal death 17 (5.4%). Associated factors of pre-eclampsia were parity, level of education, and occupation (p ≤ 0.05). Conclusion: The findings of this study showed a rising trend in the incidence of pre-eclampsia over the years at the Ho Teaching Hospital. Parity, level of education, and occupation were found to be associated with developing pre-eclampsia.

Background: Despite the advances in anesthetics and non-pharmacological techniques, the prevalence of postoperative nausea and vomiting in all patients remains high. It is one of the most common distressing symptoms that cause dissatisfaction among patients after anesthesia and surgery. A sub-hypnotic dose of propofol has been shown to reduce morphine-induced postoperative nausea, vomiting, and pruritus. This review article will provide sufficient knowledge on the role of propofol in minimizing opioid-induced postoperative nausea, vomiting, and pruritus by providing detailed information on propofol antiemetic and antipruritic effects, as well as discussions based on empirically available data. Method: We conducted a narrative review of the literature published between 1990 and 2023 from a range of databases;PubMed, BioMed Central, Biosis Previews, Nature, International Pharmaceutical Abstracts, Springer-Link, and Elsevier. Discussion and Conclusion: The literatures reviewed in this study have demonstrated that propofol may have diverse therapeutic effects including antiemetic and antipruritic. The antiemetic effect of propofol may be an effective therapeutic approach for the prevention of postoperative nausea and vomiting. The literature also demonstrated that the use of propofol for sedation during surgery may as well ameliorates opioids induced postoperative pruritus, which may be beneficial to surgical patients. Also, it was demonstrated that prophylactic use of propofol may be an effective way of preventing nausea and vomiting and pruritus during opioid use.

The changes that have taken place in Nigerian fisheries are reviewed. Artisanal fishery has continued to dominate the fisheries,contributing over 85% of total fish production. The inland water and coastal seas are fully exploited and the increase in fishery production is not likely. Aquaculture potentials remain untapped as much as deep-sea fisheries. The combined potential of the fisheries resources-freshwater,marine and aquaculture can meet over 90% of the nation's demand for fish. Opportunities for invest-ments,therefore,exist in the various subsectors,especially in the areas of storage,processing and preservation for the capture fishery and fish seed multiplication for aquaculture.

Measurement of Noise Pollution in Northern Industrial Areas of Windhoek, Namibia

引用

Journal of Environmental Protection 2019年第9期10卷 1144-1154页

作者： sylvanus Ameh Onjefu Emmanuel Ejembi Leonard Agbo Onjefu Department of Natural and Applied Sciences Namibia University of Science and Technology Windhoek Namibia Department of Civil and Environmental Engineering Namibia University of Science and Technology Windhoek Namibia

The increase in industrial activities and vehicular movement along the northern industrial area of Windhoek has vastly increased the amount of traffic noise and other noise pollution in the area. Noise pollution has an adverse health effect to human population, when exposed for a long period. Residence in proximate communities along the north industrial area and those working in the various industries located in the area may be affected, when the noise pollution level exceed the permissible standard for human exposure. A sound level meter was used to measure the amount of noise pollution at the streets of the northern industrial area. The measurements were done during the daytime, at a time interval of 2 hours, from 08:00 am - 06:00 pm. The amount of noise pollution obtained from the study ranges from (64 - 72) dB (A), with a maximum of 72 dB (A) in Bonsmara Street, (67.4 - 75.3) dB (A), with a maximum of 75.3 dB (A) in New Castle Street, (60.5 - 81.0) dB (A), with a maximum of 72.3 dB (A) in Braham Street. (62.5 - 72.3) dB (A), with a maximum of 82.3 dB (A) in Hosea Kutako Street, (66.0 - 82.3) dB (A), with a maximum of 76.8 dB (A) in Simmentaler Street and (65.1 - 76.8) dB (A), with a maximum of 76.8 dB (A) in Dortmund Street. The variation of noise level index L10, L50, L90 and Leq, Noise Climate (NC) and Traffic Noise index (TNI) were calculated. The maximum noise pollution values obtained from the study were higher than the WHO recommended limit of 70 dB (A).

Analgesic Efficacy of Intrathecal Bupivacaine with or without Morphine in Lower Limb Orthopedic Surgery. A Comparative Study

引用

Open Journal of Anesthesiology 2023年第3期13卷 58-74页

作者： Alexis Dun Bo-ib Buunaaim Comfort Adubia Fidelis Bayor sylvanus Kampo Department of Surgery School of Medicine and Health Science University for Development Studies Tamale Ghana Department of Anaesthesia and Intensive Care School of Medicine and Health Science University for Development Studies Tamale Ghana Department of Physiology School of Medicine and Dentistry University of Ghana Accra Ghana Department of Anaesthesia and Intensive Care School of Medical Sciences C. K. Tedam University of Technology and Applied Sciences Navrongo Ghana

Background: Lower limb orthopaedic surgeries are commonly associated with moderate to severe postoperative pain. Adequate pain relief is essential for patients undergoing such procedures, as uncontrolled pain can lead to delayed recovery, prolonged hospitalization, and increased morbidity. Intrathecal administration of bupivacaine, a long-acting local anesthetic, has been shown to provide effective analgesia after lower limb orthopaedic surgery. However, the duration of analgesia with bupivacaine alone is limited, and the addition of an opioid, such as morphine, can prolong the duration of analgesia. Objective: The objective of this study was to document the comparative effect of adding morphine to intrathecal bupivacaine or only intrathecal bupivacaine for lower limb trauma orthopedic surgeries in terms of onset of action, duration of analgesia, pain severity, and side effects. Methods: This was a comparative longitudinal study design conducted at the Orthopaedic Unit of the Tamale Teaching Hospital. A simple random sampling technique was used to recruit 60 patients. A standard structured questionnaire was also used to collect data on the socio-demographics, and clinical features of patients, drug used,side effects and severity of pain at 24,48 and 72 hrs after surgery. Results: Co-administration of intrathecal bupivacaine with morphine produced good and long-lasting postoperative analgesia with a mean time of 1004.25 ± 310.43 minutes, whiles using only bupivacaine produced shorter postoperative analgesia with a mean time of 294.75 ± 195.53 minutes. The p-value p values of p = 0.635 and p = 0.689 respectively. Conclusion: The study revealed that co-administration of intrathecal bupivacaine with morphine emerged as a better option for postoperative pain management after lower limb orthopedic surgeries as compared to administering only bupivacaine regarding the duration of analgesia. Milder side effects like pruritus, nausea, and vomiting were seen in group B than in
