RESUMEN

INTRODUCTION: In Sierra Leone, the lack of information on pulmonary embolism (PE) limits the access to evidence-based standard of diagnostic work-up and management of the disease. The objective of this study was to describe the clinical characteristics and management of acute pulmonary embolism in our setting and to determine whether the pre-test probability scoring algorithms were used prior to Computed Tomography Pulmonary Angiogram (CTPA) request. METHODS: This retrospective observational study was conducted on CTPA-confirmed PE patients admitted to the Intensive Care Unit, Choithrams Memorial Hospital, in Freetown, Sierra Leone between July 2014 to June 2019. Clinical data, and pertinent investigations related to PE were determined. CTPA findings were correlated with the patient's hemodynamic status. The calculated pretest clinical probability scores (PCPS) for each patient were compared to the CTPA results. RESULTS: CTPA-confirmed PE in the study cohort was 79, with a rate of 16 new PE per year. The frequency of PE was 1.9% of the total hospital admission per year. The mean age was 64.1 ± 17.9 years, median age was 63.3years (range: 23-89 years), with 55.7% of the cohort being females. Dyspnea (78.5%) and tachycardia (69.6%) were the commonest signs and symptoms documented, with immobilization (34.2%) being the prevalent risk factor, while hypertension (48.1%) was the most common co-morbidity. The PCPS algorithm was underutilized, as "Wells Score" was documented in only 9.5% while "modified Geneva score" was never used by hospital physicians. PE with hemodynamic stability was significantly more common than PE with unstable hemodynamic status [55 (69.6%) vs 24 (30.4%), p=0.015]. All patients were managed only with anticoagulants. The overall in-hospital mortality was 17.7%. CONCLUSION: Since PCPS was hardly calculated by doctors in the diagnosis of PE, the study showed that the diagnostic algorithm for suspected PE was infrequently used in clinical practice. The use of empirical judgement by doctors in requesting for CTPA may have accounted for low rate in the diagnosis of PE per year. The establishment of P.E registry in Sierra Leone is imperative.

INTRODUCTION: En Sierra Leone, le manque d'informations sur l'embolie pulmonaire (EP) limite l'accès à des normes de diagnostic et de prise en charge de la maladie fondées sur des preuves. L'objectif de cette étude était de décrire les caractéristiques cliniques et la prise en charge de l'embolie pulmonaire aiguë dans notre établissement et de déterminer si les algorithmes de notation de la probabilité pré-test étaient utilisés avant la demande d'angiographie pulmonaire par tomodensitométrie (CTPA). MÉTHODES: Cette étude observationnelle rétrospective a été menée sur des patients atteints d'EP confirmée par CTPA admis à l'unité de soins intensifs, Choithrams Memorial Hospital, à Freetown, Sierra Leone, entre juillet 2014 et juin 2019. Les données cliniques, et les investigations pertinentes liées à l'EP ont été déterminées. Les résultats du CTPA ont été corrélés avec l'état hémodynamique du patient. Les scores de probabilité clinique prétest (PCPS) calculés pour chaque patient ont été comparés aux résultats du CTPA. RÉSULTATS: Le nombre d'EP confirmées par CTPA dans la cohorte étudiée était de 79, avec un taux de 16 nouvelles EP par an. La fréquence de l'EP était de 1,9 % du nombre total d'hospitalisations par an. L'âge moyen était de 64,1 ± 17,9 ans, l'âge médian de 63,3 ans (fourchette : 23-89 ans), 55,7 % de la cohorte étant des femmes. La dyspnée (78,5 %) et la tachycardie (69,6 %) étaient les signes et symptômes les plus fréquemment documentés, l'immobilisation (34,2%) étant le facteur de risque prévalent, tandis que l'hypertension (48,1 %) était la comorbidité la plus courante. L'algorithme PCPS était sous-utilisé, le " score de Wells " n'étant documenté que dans 9,5 % des cas, tandis que le " score de Genève modifié " n'était jamais utilisé par les médecins hospitaliers. L'EP avec stabilité hémodynamique était significativement plus fréquente que l'EP avec état hémodynamique instable [55 (69,6 %) vs 24 (30,4 %), p=0,015]. Tous les patients ont été traités uniquement par anticoagulants. La mortalité globale à l'hôpital était de 17,7 %. CONCLUSION: Étant donné que le PCPS était rarement calculé par les médecins pour le diagnostic de l'EP, l'étude a montré que l'algorithme diagnostique pour l'EP suspectée était rarement utilisé dans la pratique clinique. L'utilisation d'un jugement empirique par les médecins pour demander un CTPA peut expliquer le faible taux de diagnostic de l'EP par an. L'établissement d'un registre de l'E.P. en Sierra Leone est impératif. Mots-clés: Embolie pulmonaire, caractéristiques cliniques, gestion, Sierra Leone.

RESUMEN

OBJECTIVE: To evaluate the relationship between load-carrying on the head and the development of degenerative change in the cervical spine. DESIGN AND SUBJECTS: A case-control study was performed with 35 individuals who had carried loads on their head (carriers) and 35 persons who never had carrier loads on their head (non-carriers). A scoring system was utilized for the assessment of the degenerative change in the cervical spine at the C3/C4, C4/C5, C5/C6 and C6/C7 levels on lateral cervical spine radiography. A total score was calculated by summing the scores for the single segments. RESULTS AND CONCLUSION: In 31 of the 35 (88.6%) carriers degenerative change was found in the cervical spine, but only in 8 of the 35 (22.9%) non-carriers (P < 0.01). The total score and the scores for segments C4/5, C5/C6 anc C6/C7 were significantly higher for the carriers than the non-carriers. It is concluded that the axial strain of load-carrying on the head exacerbates degenerative change in the cervical spine.

RESUMEN

This prospective study was carried out in Ghana, Sierra Leone and Nigeria. The aim was to highlight to the clinicians the common faults encountered in radiological request forms and to make recommendations aimed at improving information given on such forms which will facilitate better reporting by radiologists. 4,122 request forms from the three institutions were reviewed using a questionnaire and were analysed. The commonest fault was omission of the age of the patients; this occurred in 1,176 cases. Absence of clinical information in the request forms was noted in 946 cases and illegible entries were 658. There were 65 unconventional abbreviations used by clinicians on request forms. We recommend regular clinico-radiological meetings as continuing medical education for hospital doctors and general practitioners and also vetting of request forms for specialized radiological examinations to reduce the short-comings.

RESUMEN

An appropriate sequence of diagnostic imaging procedures which will permit a rapid; accurate diagnosis with the least number of tests and with minimum expense and disconfort to the patient. Ascites if used in the wider sense as free fluid collection within the intraperitoneal cavity; should include serous fluid; blood (bloody); urine; pus; chylous as well as galliger Ascites. In the majority of cases the clinical and laboratory evaluation of patients with ascites is sufficient to reveal the cause of fluid accumulation. However even when the cause of asctes seems pretty obvious; it is important to look for other diseases that might supervene. For example ascites by cirrhosis complicated by occult hepatoma

RESUMEN

In these days of sophisticated technology; the diagnosis of intestinal obsruction (and pseudo-obstruction) still depends almost entirely on plain X-rays and barium studies. Although rigid routines (and old myths) interfere with the interpretation of plain X-ray; nevertheless; the first step in intestinal obstruction is a series of plain X-rays without contrast. An erect; lateral left decubitus (2) supine and chest X-ray (3); (4); should be obtained because of several reasons. One of these reasons is the fact that a chest X-ray is necessary in all plain X-ray series for obstruction; in order not to be trapped into a wrong diagnosis of mechanical small bowel obstruction in pneumonia (not even only those limited to the lower lobes) and this; especially in aging adults and young children

RESUMEN

In a joint retrospective study by 17 radiotherapy clinics in German-speaking countries the results of treatment of bronchial carcinoma after radiotherapy were analysed in 7503 cases. The age peak was between the 60th and 70th year. Squamous-cell carcinoma was the most frequent histological type, followed by anaplastic carcinoma, with adenocarcinoma being rare. There was a high proportion of histologically not clearly identified cases (27% in central and 35% in peripheral carcinomas). Survival rate at one year was 31% for central (3662 patients) and peripheral (961 patients) tumours, but only 2% at five years. Prognostically there was no difference between histological types and kind of radiotherapy or technique, but total dose affected survival rate. At a total dose of less than 5000 rd the survival rate at five years was minimal. The prognosis of combined surgical and radiotherapeutic measures was slightly better than with a radiotherapy alone, but results were unpredictable for the individual case. It is concluded that radiotherapy aiming at cure should be used in imoperable bronchial carcinoma if the tumour state and general condition of the patient appear to make a cure possible. But if this is not the case, radiotherapy should be used only palliatively, i.e. only to ameliorate symptoms.
