Hepatocellular carcinoma surveillance among people living with hepatitis B in Senegal (SEN-B): insights from a prospective cohort study.

BACKGROUND: Chronic hepatitis B virus (HBV) infection is the predominant cause of hepatocellular carcinoma in west Africa, yet data on the incidence of HBV-related hepatocellular carcinoma remain scarce. We aimed to describe the uptake and early outcomes of systematic ultrasound-based hepatocellular carcinoma screening in SEN-B, which is a prospective HBV cohort in Senegal. METHODS: In this prospective cohort study, we included treatment-naive, HBsAg-positive individuals who were referred to the two infectious diseases clinics (the Department of Tropical and Infectious Diseases and Ambulatory Treatment Center) at Fann University Hospital of Dakar, Senegal, between Oct 1, 2019, and Oct 31, 2022. All participants resided within the Dakar region. Participants underwent abdominal ultrasound, transient elastography, and clinical and virological assessments at inclusion and every 6 months. Liver lesions at least 1 cm in diameter on ultrasound were assessed using four-phase CT, MRI, or liver biopsy. Adherence to hepatocellular carcinoma surveillance was measured using the proportion of time covered, calculated by dividing the cumulative months covered by abdominal ultrasound examinations by the overall follow-up time, defined as the number of months from the date of cohort entry until the last recorded visit, hepatocellular carcinoma diagnosis, or death. Optimal adherence was defined as a proportion of time covered of 100%. FINDINGS: Overall, 755 (99·6%) of 758 participants had at least one abdominal ultrasound performed. The median age of the enrolled participants was 31 years (IQR 25-39), 355 (47·0%) of 755 participants were women, and 82 (10·9%) had a family history of hepatocellular carcinoma. 15 (2·0%) of 755 individuals were HBeAg positive, 206 (27·3%) of 755 individuals had HBV DNA of more than 2000 IU/mL, and 27 (3·6%) of 755 had elastography-defined liver cirrhosis. Of ten (1·3%) participants with a focal lesion at least 1 cm at initial assessment, CT or MRI ruled out hepatocellular carcinoma in nine, whereas imaging and subsequent liver biopsy confirmed one patient with hepatocellular carcinoma. Two further patients with hepatocellular carcinoma were diagnosed at study presentation due to the presence of portal thrombosis on ultrasound. Excluding the three participants with hepatocellular carcinoma identified at baseline, 752 participants were eligible for screening every 6 months. Median follow-up time was 12 months (IQR 6-18) and the median number of ultrasounds per patient was 3 (2-4). During 809·5 person-years of follow-up, one incident hepatocellular carcinoma was reported, resulting in an incidence rate of 1·24 cases per 1000 person-years (95% CI 0·18-8·80). Overall, 702 (93·0%) of 755 participants showed optimal hepatocellular carcinoma surveillance, but this proportion decreased to 77·8% (42 of 54 participants) after 24 months. INTERPRETATION: Hepatocellular carcinoma screening is feasible in HBV research cohorts in west Africa, but its longer-term acceptability needs to be evaluated. Long-term hepatocellular carcinoma incidence data are crucial for shaping tailored screening recommendations.

Contained rupture of a left renal artery aneurysm: Report of a case.

Ruptured renal artery aneurysms are uncommon. Although the increased use of endovascular technologies, controversy persists over the management. Contained rupture may be more difficult to diagnose, hence delay the management. We report a case of contained rupture of renal artery aneurysm treated with selective embolization prior to nephrectomy.

Interest of preoperative embolization of aneurysmal bone cyst (ABC): A case report.

Aneurysmal bone cyst (ABC) is a rare lesion that primarily affects young adults and children. The optimal treatment approach for ABC remains controversial and varies depending on the preferences of the medical team. While some advocate for surgery as the treatment of choice, others recommend a less invasive first-line option such as selective embolization. In this case report, we present the case of a 41-year-old female patient with an ABC in the right iliac bone who underwent surgical treatment following preoperative selective embolization. Additionally, we provide a literature review on the topic.

Hydrocèle de l'adulte: le surjet hémostatique au cours de la cure, est-il utile sur les berges de la vaginale réséquée au bistouri électrique ? / Adult hydrocele surgery: is the hemostatic running suture useful after resection and electrocoagulation of the tunica vaginalis edge?

Contexte et objectifs. L'hydrocèle conduit dans ses formes évoluées à un retentissement psycho-social, économique et anatomique. Les objectifs de l'étude étaient de décrire les aspects cliniques et le devenir sous traitement de l'hydrocèle vaginale de l'adulte (HVA). Méthodes. Etude documentaire descriptive réalisée, au Centre hospitalier régional Amadou Sakhir Mbaye (CHRASM) de Louga, Sénégal ayant enrôlé des patients de 19 ans et plus présentant une hydrocèle, opérée selon la même technique entre janvier 2011 et décembre 2017. L'opération a consisté en une résection de la vaginale à 0,5 cm du testicule suivi d'hémostase au bistouri électrique, sans surjet hémostatique. Résultats. 1538 patients ont été opérés dont 69 pour HVA (4,5 %) et trente-neuf (n=39) d'entre eux étaient retenus. Leur âge moyen était 61,7 ± 21,3 ans. Le principal motif de consultation était : l'aspect volumineux et inesthétique des bourses. Un total de 48 unités d'hydrocèle ont été opérées : droites (n=19), gauches (n=11) et bilatérales (n=9). La vaginale était épaissie pour l'ensemble des cas. Les suites opératoires ont été simples. Aucun décès. À six mois, les patients étaient satisfaits, aucune récidive. Conclusion. HVA est une pathologie relativement courante dans notre pratique. La résection de la vaginale avec hémostase au bistouri électrique sans surjet hémostatique est une technique sûre et efficace

Context and objectives. Adult hydrocele is a relatively common pathology that causes psychosocial, economic and anatomical repercussions. The objectives of this study were to describe the clinical features and the outcome of hydrocele. Methods. This retrospective study included adults operated for hydrocele, in the Department of Urology of Louga Hospital, from January 2011 to December 2017. The operation begins by a scrotal skin incision that is carried down to the parietal tunica vaginalis which is opened and the content aspirated. Parietal tunica vaginalis is excised. Hemostasis is achieved by only electrocoagulation. Testicle is reintegrated, the wound closed without drain and protected by the dressing. Results. 1538 patients underwent surgery including 69 patients (4.5 %) for adult hydrocele. However, 39 out of these 69 patients (61.7 ± 21.3 years) were enrolled in the present study. Thirty-five were married and the others were unmarried (n=4). The main complaints for patients were inesthetic and scrotal swelling, interference and difficulties in socio-professional activities, negative social comments. The mean duration of the hydrocele evolution was 4 years. Operation procedures were done under spinal (n=38) or general anesthesia (n=1). A total of 48 hydroceles were cured including 11 on the left side, 19 on the right side and 9 bilateral. The mean volume aspirated was 600 ml. The tunica vaginalis was thick in all cases and calcified in 15 cases of hydrocele. No complications (hematoma or wound infection) were observed. No deaths or recurrences were recorded. Six months following the surgery, all patients were satisfied. Conclusion. Adult hydrocele is relatively common in the Department of Urology of Louga Hospital. The treatment consisting in excision of the tunica vaginalis, hemostasis by electrocoagulation, without hemostatic running suture is safe, secure and effective.

Devenir des pathologies du canal péritonéo-vaginal et de la migration testiculaire chez l'enfant: prise en charge au centre hospitalier de Louga, Sénégal / Outcome of processus vaginalis and testicular migration related pathologies in children treated at Louga Hospital, Senegal

Contexte et objectifs. Le devenir des pathologies du canal péritonéo-vaginal (CPV) et de la migration testiculaire chez l'enfant est peu connu. L'objectif de ce travail était de décrire les aspects cliniques et le devenir de ces pathologies. Méthodes. Etude documentaire descriptive portant sur les hernies, hydrocèles, cryptorchidies et torsions du cordon spermatique opérées chez le garçon âgé de 0 à 16 ans, au Centre hospitalier de Louga, Sénégal, de janvier 2018 à décembre 2019. Résultats. 184 dossiers des patients ont été colligés, soit 32,5 % de patients opérés au cours de la période. Leur âge moyen était de 5,4 ± 4,3 ans. Ces pathologies englobaient : hernies inguinales (n=37 dont 3 étranglements), hydrocèles (n=113), cryptorchidies (n=27), testicules oscillants (n=2) et torsions du cordon spermatique (n=5). L'abord a été inguinal dans 96,1 %. Le traitement a consisté en : ligature du CPV, abaissement testiculaire, orchidopexie, orchidectomie. Aucune récidive, atrophie ou fonte testiculaire n'a été observée en trois mois de suivi. Conclusion. La prise en charge en urgence ou non des pathologies du CPV et de la migration testiculaire chez l'enfant est fréquente dans notre pratique, sans complication à courte terme. Le défi réside dans le suivi à long terme en raison des complications tardives

Context and objectives. Little is known about the outcome of patent processus vaginalis and testicular migration pathologies in children. The objectives of this study were to analyze clinical and therapeutic features of these pathologies. Methods. This was a descriptive retrospective study involving boys aged 0 to 16 years, operated for inguinal hernias, hydroceles, cryptorchidisms and testicular torsions, at the Louga Regional Hospital Center, Senegal, from January 2018 to December 2019. Results. 184 patients were recorded, which represented 32.5 % of all patients operated in the same period. Their average age was 5.4 ± 4.3 years. The managed pathologies were: inguinal hernias (n= 37 including 3 incarcerated hernias), hydroceles (n= 113), cryptorchidisms (n= 27), retractile testicles (n=2) and testicular torsions (n= 5). Inguinal approach was performed in 96,1 % of cases. Surgical managements were: ligature of the patent processus vaginalis, relocating the testicle within the scrotum, orchidopexy and orchidectomy. No recurrence, no purulent testicular discharge or testicular atrophy was encountered. Conclusion. Processus vaginalis and testicular migration pathologies are common in our practice. At 3 months of surgical operation, no complication was observed. However, the challenge is long-term follow-up due to late complications

Sturge Weber syndrome, when brain CT is enough for diagnosis: about a case.

One of the main manifestations of Sturge Weber syndrome is seizures. We report the case of a child received in the context of generalized seizures and in whom a cerebral contrast CT was sufficient to make the diagnosis of Sturge Weber syndrome.

False ground-glass opacity and suspicion of COVID-19, beware of the technique for performing the CT.

Ground-glass opacity is a CT sign that is currently experiencing renewed interest since it is very common in patients with COVID-19. However, this sign is not specific to any disease. Besides, the possibility of false positive ground-glass opacity related to insufficient inspiration during the acquisition of the chest CT should be known. We report the case of a 36-year-old patient suspected of COVID-19 and in whom a second acquisition of chest CT was necessary to remove false ground-glass opacities that erroneously supported the diagnosis of COVID-19.

Late diagnosis of imperforate hymen with hematometrocolpos and bilateral hydronephrosis of a horseshoe kidney.

Imperforate hymen is a fairly uncommon genital disorder where the hymen completely obstructs the vaginal opening. Several authors have ruled out its co-occurrence with other congenital anomalies. In this report, we discuss the exceptional case of a late diagnosis of imperforate hymen associated with bilateral hydronephrosis of a horseshoe kidney in a 19-year-old female patient. To our knowledge, an association of imperforate hymen and horseshoe kidney has never been reported.

[Acute scrotal swellings at Louga Regional Hospital, Senegal: epidemiologic, etiologic and therapeutic aspects]. / Les grosses bourses aiguës au centre hospitalier de Louga, Sénégal: aspects épidémiologiques, étiologiques et thérapeutiques.

INTRODUCTION: Acute scrotal swellings (ASS) are a common reason for emergency consultation. This study aims to determine the frequency of hospitalization for ASS at the Louga Amadou Sakhir Mbaye Regional Hospital, Senegal, to identify its clinical forms and to evaluate the care management. METHODS: This is a retrospective descriptive study involving 114 patients hospitalized for ASS at the Louga Amadou Sakhir Mbaye regional hospital, from May 2010 to August 2013. The variables studied were: the frequency of ASS among scrotal swellings and urological emergencies, age, consultation period, causes, treatment, post-treatment evolution and hospitalization length. RESULTS: During the study period, 356 scrotal swellings and 420 urological emergencies were recorded. Thus, 114 cases with ASS accounted for 32.0% of scrotal swellings and 27.1% of urological emergencies. The average age was 42.25 ± 25 years (5 months and 89 years represent the extremes). The median of consultation time was 4 days. The diagnosis at admission was: acute orchiepididymitis (n=66), ASS with abscess formation (n=18), suspicion of torsion of the spermatic cord (n=14), traumatic ASS (10 cases), strangulated inguinoscrotal hernia (06 cases). Treatment was exclusively medical in 66 cases (57.8 %). Surgical exploration, which was indicated in 48 patients, was performed in 45 of them (93.7%), three patients (6.2%) refused it. In total there were 9 cases with orchiectomies and 36 conservative procedures. The average length of stay in hospital was 3 ± 2 days. Eighty-one patients (71.0%) were hospitalized for at least 24 hours. They were divided into two groups: 42 surgical patients and 39 medical patients. No deaths were recorded. CONCLUSION: ASS are common in our hospital, people of all ages can be affected. They are dominated by ASS of infectious origin, torsion of the spermatic cord and scrotal trauma. Delayed consultation is often the rule, this may affect functional prognosis of the testicle.

Traumatic diaphragmatic injuries: epidemiological, diagnostic and therapeutic aspects.

INTRODUCTION: Diaphragmatic injuries include wounds and diaphragm ruptures, due to a thoracoabdominal blunt or penetrating traumas. Their incidence ranges between 0.8 and 15 %. The diagnosis is often delayed, despite several medical imaging techniques. The surgical management remains controversal, particularly for the choice of the surgical approach and technique. The mortality is mainly related to associated injuries. The aim of our study was to evaluate the incidence of diaphragmatic injuries occuring in thoraco-abdominal traumas, and to discuss their epidemiology, diagnosis and treatment. PATIENTS AND METHODS: We performed a retrospective study over a period of 21 years, between January 1994 and June 2015 at the Department of General Surgery of the Aristide Le Dantec hospital in Dakar, Senegal. All patients diagnosed with diaphragmatic injuries were included in the study. RESULTS: Over the study period, 1535 patients had a thoraco-abdominal trauma. There were 859 cases of blunt trauma, and 676 penetrating chest or abdominal trauma. Our study involved 20 cases of diaphragmatic injuries (1.3 %). The sex-ratio was 4. The mean age was 33 years. Brawls represented 83.3 % (17 cases). Stab attacks represented 60 % (12 cases). The incidence of diaphragmatic injury was 2.6 %. The wound was in the thorax in 60 % (seven cases). Chest radiography was contributory in 45 % (nine cases). The diagnosis of wounds or ruptures of the diaphragm was done preoperatively in 45 % (nine cases). The diaphragmatic wound was on the left side in 90 % (18 cases) and its mean size was 4.3 cm. The surgical procedure involved a reduction of herniated viscera and a suture of the diaphragm by "X" non absorbable points in 85 % (17 cases). A thoracic aspiration was performed in all patients. Morbidity rate was 10 % and mortality rate 5 %. CONCLUSION: The diagnosis of diaphragmatic rupture and wounds remains difficult and often delayed. They should be kept in mind in any blunt or penetrating thoraco-abdominal trauma. Diaphragmatic lesions are usually located on the left side. Surgery is an efficient treatment.

INTRODUCTION: Les traumatismes du diaphragme comprennent les ruptures et les plaies du diaphragme. Leur incidence varie entre 0,8 % et 15 %. Elles sont très souvent méconnues malgré les techniques performantes d'imagerie médicale. Leur prise en charge chirurgicale reste controversée. La mortalité de cette pathologie est liée aux lésions associées. Le but de notre étude était d'apprécier l'incidence des lésions diaphragmatique dans les traumatismes thoraco-abdominaux, et de discuter les aspects épidémiologiques, diagnostiques et thérapeutiques. PATIENTS ET MÉTHODE: Il s'agissait d'une étude rétrospective sur 21 ans allant du 1er janvier 1994 au 30 juin 2015. Cette étude a été réalisée au Service de Chirurgie Générale de l'Hôpital Aristide Le Dantec de Dakar. Etaient inclus dans cette étude tous les patients qui présentaient une lésion diaphragmatique consécutive à un traumatisme abdominal et/ou thoracique ouvert ou fermé. RÉSULTATS: Durant cette période d'étude, nous avons reçu 1535 patients victimes de traumatisme thoracique et/ou abdominal. Il s'agissait de 859 cas de contusions et 676 cas de plaies thoraciques et/ou abdominaux. Notre étude portait sur 20 cas de lésions diaphragmatiques (1,3 %). Le sex-ratio était de 4. L'âge moyen était de 33 ans. Les agressions par arme blanche représentaient 60 % (12 cas). L'incidence des lésions diaphragmatiques était de 2,6 %. La plaie cutanée était de siège thoracique dans 60 % (7 cas). La radiographie du thorax était contributive dans 45 % (9 cas). Le diagnostic de lésion diaphragmatique était préopératoire dans 45 % (9 cas). La brèche diaphragmatique siégeait à gauche dans 90 % (18 cas) et la taille moyenne était de 4,3 cm. Le geste chirurgical avait consisté en une réduction des viscères herniés et une suture du diaphragme par des points en « X ¼ dans 85 % (17 cas). Le drainage thoracique était systématique. Le taux de morbidité était de 10 % et la mortalité de 5 %. CONCLUSION: Leur diagnostic est difficile. Elles siègent le plus souvent à gauche. Leur traitement est chirurgical et la voie d'abord préférentielle est la laparotomie.
