[Abdominal ultrasound abnormalities incidentally discovered in patients with asymptomatic HIV in Lome (Togo)]. / Anomalies échographiques abdominales de découverte fortuite chez le patient VIH asymptomatique à Lomé (Togo).

Few studies have examined ultrasound imaging of abdominal manifestations of HIV-AIDS, although these rank second only to its pleuropulmonary manifestations. Thus, this study sought to determine the features of abdominal ultrasound in HIV infection. This prospective, descriptive and analytical study took place in the radiology department of the University Hospital Campus Lomé and covered the three-year period of 2009-2011. It included all patients older than 15 years with positive HIV serology. During the study period, 566 patients met the inclusion criteria. Ultrasound examination showed the liver appeared normal in 153 patients (27.0%), but homogeneously hyperechoic and thus suggestive of hepatic steatosis in 107 (18.9%). The bile duct was dilatated in 12 patients or 2.1%. An anomaly in the corticomedullary differentiation in normal-sized kidneys was noted in 28.1% (159 patients). Diffuse homogeneous hypertrophy of the pancreas was found in 3 patients (0.53%). Splenomegaly was noted in 387 patients (68.4%); the echopattern of the spleen was diffusely micronodular in 6 patients (1.1%). Deep adenopathies were found in 29 patients (5.1%) and ascites in 46 patients (8.1%). Abdominal ultrasound is a medical imaging technique available in developing countries, less expensive than others, which can be considered an alternative to computed tomography (CT) in the countries of sub-Saharan Africa for the exploration of the abdominal manifestations of HIV.

[Anencephaly in twin pregnancy: a series of 6 cases]. / Anencéphalie sur grossesse gémellaire : une série de six cas.

OBJECTIVE: To report a series of cases of anencephaly in twin pregnancies and assess the prognosis of the normal twin. PATIENTS AND METHODS: Retrospective study covering 4 years, at the CHU Campus in Lomé, assessing the sonographic aspects and management of cases of anencephaly in twin pregnancies. RESULTS: Anencephaly was found in 6 twin pregnancies. The mothers' mean age was 31 years and all had a very low socioeconomic status. All had drunk a plant infusion of an unknown chemical composition in early pregnancy. Mean gestational age at diagnosis was 25 weeks. Ultrasound performed in all cases showed that 5 cases involved monochorionic diamniotic placentas, and 1 case a dichorionic placenta. Both fetuses were alive at diagnosis in all cases: one had anencephaly and the other twin was normal. The average estimated weight of the anencephalic twin at diagnosis was 659 grams, and of the normal twin, 749 grams; growth was thus discordant. Hydramnios was noted in all cases. Expectant monitoring was instituted; both twins died before 30 weeks in 4 cases. CONCLUSION: Anencephaly in twin pregnancy is a rare occurrence. Ultrasound can be involved in the diagnosis and management.

[Hygiene of transvaginal ultrasound probes in a developing country: case of Togo]. / Hygiène des sondes d'échographie endovaginale dans un pays en développement : cas du Togo.

The purpose of this study was to assess the knowledge and practices of hygiene rules for transvaginal ultrasound by sonographers practicing in Togo. Their knowledge of these rules is good. In practice, they mainly use condoms to protect the vaginal probe, which is sufficient to prevent horizontal transmission of infection. The shortcomings are at the level of hand hygiene; they do not routinely wash hands or wear gloves, nor do they follow guidelines for disinfection of the probes.

[Chylous ascites, a revealing sign of peritoneal tuberculosis in an 11-month-old infant]. / Ascite chyleuse révélatrice d'une tuberculose péritonéale chez un nourrisson de 11 mois.

Chylous ascites is rare in children. We report on a case of chylous ascites in an 1-month-old infant in Togo. The infant had been appropriately vaccinated, had normal growth and psychomotor development, and he was living in a rural area. He had fever that had started 3 months earlier and persisted despite various treatments with antimalarials and antibiotics. Then progressively abdominal pain with abdominal distension developed, while lactescent ascites was discovered after puncture. The patient was referred to the Lomé teaching hospital for advanced management. Intradermic reaction to tuberculin (IRD) was positive (16 mm). Chylous ascites liquid analysis revealed apparently lymphocytic pleocytosis. Culture on special milieu allowed isolation of Mycobacterium tuberculosis. The clinical course was favorable with antituberculosis treatment. Peritoneal tuberculosis should be suspected in endemic areas in the case of a persistent fever with abdominal bloating and effusion, whatever the patient's age and the nature of ascites liquid.

[System of telesonography with synchronous teleconsultations and asynchronous telediagnoses (Togo)]. / Système de télé-expertise échographique temps réel et de télédiagnostic échographique temps différé. Étude pilote au Togo.

INTRODUCTION: Ultrasonography is an important nonirradiating diagnostic medical imaging procedure, frequently used, especially in urgent circumstances. This relatively inexpensive noninvasive examination makes it possible to diagnose disorders in various parts of the human body, by examining, for example, the abdomen and pelvis, the cardiovascular system, and the muscles and joints. Ultrasound is also an operator-dependent examination, in that the quality of the result depends on precision in the manipulation of the probe. Unfortunately, many small medical centers and isolated sites do not have an appropriate well-trained sonographer to perform initial evaluations, and an untrained operator cannot capture the appropriate echographic views required for a safe diagnosis of current patients, even with realtime vocal guidance (personal data). The lack of experienced physicians or qualified technicians means that diagnostic ultrasound is not always accessible to patients for rapid examination worldwide, especially in Africa, Amazonia or near the North or South Poles. This situation has led to the development of a new concept of telemedicine: telesonography, with a remote ultrasound diagnosis either in real time (synchronous) or delayed (asynchronous; store-and-forward). These systems of real-time telesonography and data transmission require expensive and complex technology with sophisticated equipment not available in many developing countries. The purpose of this study is to design a low-cost real-time system of telesonography for teleconsultations with experts and a delayed telediagnostic mode between isolated peripheral hospitals and a University Hospital center (UHC). METHODS AND MATERIALS: An IP camera and an internet video server were installed in a geographically isolated site equipped with an ultrasound machine and an operator with basic training in its use. Synchronous teleconsultation (second-opinion diagnosis) is possible via internet with a UHC expert. If no ultrasound operator is available at the isolated center, volume capture-and-store software is used. Later on, the UHC expert uses Echo-Cnes 3D software to reconstruct the organs scanned. The expert can then navigate within the reconstructed volume and display any plane. Volume capture is performed by tilting (± 40°) to both sides vertically to the skin. To locate the probe on the organ acoustic window, the novice operator uses acoustic window mapping designed by our laboratory (UMPS-Tours). The system was tested between the Tsévié regional hospital in Togo (40 km from Lomé, Togo, and 4500 km from Tours, France) and the UHC at Lomé and the Trousseau UHC in Tours. RESULTS: With an average internet connection of 2 Mbps, the quality of transmission of the background video and ultrasound sequence videos from Tsévié towards Lomé was satisfactory (16 images/s) with a maximal transmission delay of 1.5 s (almost in real time). A video conference between the Trousseau UHC in Tours, the UHC Campus in Lomé and the Tsévié Hospital was possible and the bandwidth allowed the Lomé experts (radiologists) to perform real-time telesonography with very satisfactory results (ultrasound diagnoses obtained) for abdominal (n = 5), pelvic (n = 3), obstetric (n = 2), prostate (n = 2) and mammary (n = 2) ultrasound, both normal and pathological. Because the doctors at Tsévié had minimal experience with ultrasound, complete ultrasound diagnoses were obtained by combining remote voice instruction for image capture and full diagnosis by Echo-Cnes. Asynchronous telediagnosis was also performed with Tsévié operators who lacked ultrasound expertise but could perform the required tilt movements (after 3 training sessions). The expert at Trousseau UHC performed real-time telesonography with the Tsévié Hospital for two cases requiring abdominal images and another viewing of the prostate. He also performed asynchronous reconstruction of the abdominal organs with Echo-Cnes. A demonstration seminar of our platform was organized successfully for 2 days during the 9(th) Congress of the French-speaking Black Africa Society of Radiology (SRANF in French) held from 4 till 6 May 2011 at the hotel EDA OBA. During this seminar, 4 ultrasound teleconsultations were performed from the hotel by eminent African radiologists. DISCUSSION AND CONCLUSION: This preliminary study, although limited in the number of patients, allowed us to assess the technical features of our telesonography system. Togo, a developing country with a very modest infrastructure for information and communication, was an ideal site for a first test of this platform. Our system of remote ultrasound requires the local patient center to be equipped simply with a 2D ultrasound machine. The cost is quite low, in comparison to the asynchronous techniques requiring 3D devices. The high cost of 3D or 4D ultrasound machines and their fragility make it difficult to install them at the isolated sites and was a serious obstacle in the development of this system. If the center already has a 2D device and a computer, the cost to equip it with the remaining communications materials is 1,500 €. The experience in Togo clearly highlighted the possibility of teletraining and complete teleradiology with our system. The next stage of this work will seek to validate the results of this preliminary experience on a larger sample with more precise assessment criteria in 2012. The results will allow the widespread dissemination and routine use of this system in developing countries.

Preliminary experience with tele-sonography and tele-mammography in Togo.

Many medical centres are equipped with a sonograph. However, a sonographist is not always present or is not trained in all of the specialised domains of sonography. . A sonogram is not always possible due to a lack of physicians. This situation has given rise to the concept of remote-controlled sonography: tele-sonography, a medical procedure used in remote sonographic diagnosis in real time or deferred time. Tele-sonography can now be carried out in real time by the transmission of the expert's procedure (robotic system) or by the use of a 3D sonograph in real time. These modes of real time tele-sonography rely on expensive technologies requiring budgets and an infrastructure that is not always possible in developing countries where the needs in tele-medicine are increasing. This paper aimed to present a preliminary evaluation of a "low cost" system of sonographic tele-expertise in real time and the deferred sonographic telediagnosis accompanied by a tele-mammography between expert sites (university hospitals) and isolated sites (peripheral hospitals, dispensaries).

[Diagnostic ultrasonographique d'une hernie inguino-labiale a contenu utero-ovarien. a propos d'une observation chez un nourrisson]. / Diagnostic ultrasonographique d'une hernie inguino-labiale a contenu utero-ovarien. a propos d'une observation chez un nourrisson.

Although indirect sliding inguinal hernias containing the ipsilateral ovary and fallopian tube are not uncommon in infant girls, those containing the uterus, ovary and fallopian tube are. We present the case of a 1-month-old girl with a palpable barely movable mass over the left labium major. Preoperative sonography was performed and revealed a hernia containing the uterus, ovary and fallopian tube. This diagnosis was confirmed during surgical correction. We suggest sonography be used for all diagnostic workup in female infants with an inguinal mass.

Bien que les hernies inguinales contenant l'ovaire homolatéral et la trompe soient relativement fréquentes chez la petite fille, celles contenant l'utérus, un ovaire et la trompe sont rares. Nous rapportons un cas chez une petite fille de 1 mois, né à terme présentant une masse peu mobile de la grande lèvre gauche. Une échographie réalisée a mis en évidence un sac herniaire contenant l'utérus, un ovaire et vraisemblablement la trompe ipsilatérale. Ce diagnostic a été confirmé durant l'opération. Nous suggérons que l'échographique soit mis à profit dans le diagnostic de toute formation inguinale de la petite fille.

[Kidney ultrasound scan performed on the adult patient with HIV serology positive in the University Hospital of Tokoin and campus of Lome]. / Echographie renale chez le sujet adulte porteur du VIH aux CHU Tokoin et campus de Lome.

PURPOSES: To describe the elementary lesions, to list the kidney pathologies, to determine the kidney reach frequency and to establish an interrelationship enters the gravity of the kidney reach and the kidney's structure at the ultrasound scan. PATIENT AND METHOD: It was about a prospective survey of ten (10) month, realized in the Departments of radiology of the Teaching Hospitals of Lomé (CHU Tokoin and Campus), concerning 281 patients aged of 18 to 71 years whose HIV serology is positive. RESULTS: The radiological frequency of the HIV/AIDS infection noted during our period of survey was of 3.27% (281/8583). The modal age group was of 30-40 years (32.38%). The female representativeness was 56.92% against 43.08% of men. The drivers (23.13%) follow-ups of the tradesmen were the more touched. The bachelors were more exposed (38.43%). The kidney increased size in 31.85% of the cases. The majority of the patients (88.19%) was at the echographic advanced stage of the renal suffering of which 70.08% were at the III stage. The length of the kidneys was generally normal (74.38%), their width was normal in 53.38% of the cases and increased in 44.42% of the cases. As for the thickness, it was increased in general (71.88%). The kidney suffering (49.03%) was the most dominant pathology. CONCLUSION: The wealth of the kidney pathology associated to the infection of the HIV/AIDS should bring the practitioners to integrate the ultrasound scan in the balance of this affection.

[Tuberculosis in newborns in a tropical neonatology unit]. / Tuberculose du nouveau-né dans une unité de néonatologie tropicale.

UNLABELLED: We report three cases of tuberculosis observed in a neonatal unit in a country characterized with a high endemia of tuberculosis. CASE REPORTS: Case 1. A term infant presented at the age of 35 days, with cough since day 18, respiratory distress and bronchopneumonia. Her mother had unrecognised tuberculosis since pregnancy. Post mortem biopsies of the infant confirmed the diagnosis of tuberculosis and social survey found out pulmonary tuberculosis in the newborn's aunt. Case 2. A term infant presented at the age of 30 days with cough since day 13, respiratory distress, nodular pulmonary lesions and right pleural effusion. Her mother had cough and stomatitis since the eighth month of pregnancy and nodular pulmonary lesions. Tuberculosis and HIV were confirmed in the mother and the infant. Social survey found tuberculosis in the newborn's paternal uncle. Case 3. A term but hypotrophic infant presented on the first day of life, with haemorrhagic troubles and respiratory distress. Tuberculosis and HIV were confirmed in the mother and the infant. Social survey found tuberculosis in the father, in a friend of her and in her three-month-old child. CONCLUSION: Congenital or neonatal tuberculosis is an under-estimated emergent disease, with a need for early diagnostic methods and consensual therapeutic protocols to improve its management.
