RESUMO

INTRODUCTION: Our objective was to evaluate the management of chronic renal failure in hemodialysis at the Edith Lucie Bongo Ondimba General Hospital (HGELBO). MATERIALS AND METHODS: This was a cross-sectional and analytical study over a 10-month period from March 1, 2018 to December 31, 2018. This included all patients aged 16 and over whohad at least one treatment session hemodialysis during the study period. The sociodemographic, clinical, biological, therapeutic and evolutionaryparameters of the patients werenoted. And data entry wasdoneusing Excel 2013 and EPI Infos version 3 software with a p <0.05 consideredstatisticallysignificant. RESULTS: The number of patients hospitalized for chronic and acute renal failurein 10 months was 101 patients, of whom 97 received hemodialysis treatment. The sex ratio was 1.4 with 59% males. The meanagewas 49.19 ± 28.4 years. The most affected intervalisbetween 50 and 59 years old with 19 patients or 29.68%. The patients came from Brazzaville in 60.93%. The first indication of hemodialysis wasuremiapoorlytoleratedin 81, 25% of cases. Diabeticnephropathywas the leading cause of CKD in hemodialysis. Meanserumcreatinine at initiation of hemodialysis was128.5 ± 75.12 mg / l. The incidence of HIV in hemodialysis is 6.4%, those of hepatitis B and C are 1.25% respectively. There were 54 patients (84.37%) whobenefited from femoralcatheter placement at baseline. We have so far 7 deaths out of 64 patients. CONCLUSION: This center of hemodialysis contributes to the improvement of the management of the renal insufficiency in the stage of hemodialysis. The assessment of this work reveals strong and weak points and we are consideringother work, more hemodialysis stations and itwould be interesting to do some work on the prevalence of renal disease in the Republic of Congo.


INTRODUCTION: Notre étude avait pour objectif d'évaluer la prise en charge des insuffisants rénaux chroniques en hémodialyse à l'Hôpital Général Edith Lucie Bongo Ondimba (HGELBO). MATÉRIELS ET MÉTHODES: Il s'agissait d'une étude transversale et analytique sur une période de dix mois s'étendant du 1er mars 2018 au 31 decembre 2018. Étaient inclus tous lespatients âgés de 16 ans ou plus, ayant bénéficié d'au moins une séance d'hémodialyse durant la période de l'étude. Les paramètres sociodémographique, clinique, biologique, thérapeutique et évolutif des patients ont été relevés. Et la saisie des données a été réalisée en utilisant les logiciels Excel 2013 et EPI Infos version 3 avec un p <0,05 considérée comme statistiquement significative. RÉSULTATS: Le nombre de patients hospitalisés pour insuffisance rénale chronique et aigue en 10 mois a été de 101 patients parmi lesquels 97 ont bénéficié du traitement d'hémodialyse. Le sex ratio a été de 1,4 avec 59 % de sexe masculin. L'âge moyen a été de 49,19 ± 28,4 ans. L'intervalle le plus touché est compris entre 50 et 59 ans avec 19 patients soit 29,68%. Les patients venaient de Brazzaville dans 60,93%. La première indication d'hémodialyse a été l'urémie mal tolérée dans 81, 25% des cas. La néphropathie diabétique a été la première cause de l'IRC en hémodialyse.La moyenne dela créatininémie à l'initiation de l'hémodialyse a été de128,5±75,12 mg/l. L'incidence du VIH en hémodialyse est de 6,4%, celles des hépatites B et C sont de 1,25% respectivement. Il y a 54 patients soit 84,37 % qui ont bénéficié de la pose cathéter fémoral à l'inclusion. Nous avons à ce jour 7 décès sur 64 patients. CONCLUSION: Ce centre d'hémodialyse contribue à l'amélioration de la prise en charge des insuffisants rénaux en stade d'hémodialyse. L'évaluation de ce travail révèle des points fort et faible et nous envisageons d'autres travaux, plus des postes d'hémodialyse et il serait intéressant de faire un travail sur la prévalence de la maladie renale en République du Congo.

RESUMO

OBJECTIVE: To study the effects of prolonged administration of Dacryodes edulis (G. Don) H.J. Lam (HDE) fruit oil on the symptoms of anxiety and cognitive performance in mice. METHODS: Anxiolytic activity and effects of HDE (5 and 10 ml/kg) on cognitive performance were evaluated in male mice after oral administration for 45 days. Anxiolytic effects were investigated in open field test, elevated plus Maze and hole board test. The Morris Water Maze test was used to evaluate cognitive performance in mice. Efficacy of HDE (5 and 10 ml/kg) was compared with that of fluoxetine (2 mg/kg p.o). RESULTS: HDE decreases the total distance traveled, significantly increases the number of adjustments and the number of entries in the central area of open field. In the elevated cross labyrinth test, HDE increases the number of entries and the time spent in the open arms. HDE significantly increases the number of head insertion into the holes. In the Morris Water Maze test, HDE reduces latency before finding the platform and increases the time spent in the target quadrant. CONCLUSION: The results confirm anxiolytic effects and improved cognitive performance after prolonged oral administration of HDE in rodents.

RESUMO

Les adénopathies cervicales chroniques sont celles qui évoluent depuis plus de trois semaines de façon non résolutive. Elles posent un problème de diagnostic étiologique et peuvent annoncer une affection grave. Matériel et méthodes : Il s'est agi d'une étude descriptive et rétrospective allant du 01 juillet 2007 au 31 juillet 2017, soit une période de 10ans. Cette étude s'est déroulée dans les services d'ORL du CHU-B et de l'Hôpital Général Adolphe SICE. Résultats : Au total 100 cas d'adénopathies cervicales chroniques ont été colligés en 10 ans, soit une prévalence de 1,8%. Le sex-ratio était de 1,17 et la tranche d'âge la plus représentée était celle de 20 à 29 ans avec une moyenne d'âge de 30,8±15,8 ans. La plupart des patients avaient une poly-adénopathie cervicale et une fièvre comme signe associé (64% des cas). Les lésions histopathologiques en cause étaient la tuberculose ganglionnaire (49%), les lymphomes ganglionnaires (21%), les adénites réactionnelles (15%), les métastases des carcinomes (11%) l'histiocytose ganglionnaire (2%) et la maladie de CASTLEMAN (2%).Conclusion : La pathologie ganglionnaire cervicale au Congo reste dominée par la tuberculose, suivie des proliférations lymphoïdes malignes et réactionnelles. L'examen anatomo-pathologique standard est complété par une étude immunohistochimique pour un diagnostic étiologique plus précis

RESUMO

Introduction : La co-infection VIH-VHB constitue un facteur important de morbi-mortalité dans les pays en développement. L'objectif était d'étudier l'effet de la co-infection sur le taux de lymphocytes TCD4+ et la fonction hépatique des patients.Matériels et méthode : Il s'est agi d'une étude rétrospective transversale descriptive et analytique menée à l'hôpital central des armées de Brazzaville du 1er janvier 2015 au 30 septembre 2016. Les données ont été analysées par les logiciels Excel et SPSS 21.Résultats : Cinquante-huit patients étaient porteurs de l'antigène HBs, la séroprévalence hospitalière était de 6,3%. Les tranches d'âges représentatifs étaient de 18 ans à 29 ans et de 30 ans à 39 ans dans (34,62%). Le sex-ratio (H/F) était de 0,5. La co-infection représentait 37,18%. Le taux de lymphocytes TCD4 était inférieur à 200/mm3 chez 61,54% des patients. Le taux de lymphocytes TCD4 était plus bas chez les co-infectés que chez les mono-infectés VIH ; (P-Valeur = 0.000).Conclusion : La co-infection VIH/VHB a un impact négatif sur la fonction hépatique et l'immunité des patients

RESUMO

BACKGROUND: Coxsackieviruses B (CV-B) are enteroviruses that have been reported to play a role in the pathogenesis of type 1 diabetes. Enteroviral RNA was detected in the gut mucosa of patients. The mucosal immunity is an interconnected network; therefore, the response to enteroviruses possibly present in the gastrointestinal mucosa can be reflected by specific antibodies in the saliva. In the present study, the anti-CV-B neutralizing activity of saliva samples from patients with type 1 diabetes was investigated. METHODS: Saliva samples were collected from patients and controls of 3 countries, and plasma was obtained from some of them. The anti-CV-B activity of clinical samples was determined by neutralization of the cytopathic effect induced by challenging viruses in vitro and expressed as titre value. RESULTS: Overall prevalence and levels of anti-CV-B4 activity of saliva were higher in patients (n = 181) than in controls (n = 135; P = .0002; titre values ≥ 16: odds ratio = 4.22 95% CI: 1.90-9.38 P = .0002). It has been shown that IgA1 played a role in this activity. There was no correlation between the saliva and the plasma anti-CV-B4 neutralizing activity. The neutralizing activity of saliva against CV-B1, CV-B2, CV-B3, and CV-B5 existed rarely, if at all. Increased levels of anti-CV-B4 activity were observed all along a 4 year follow-up period in patients but not in matched controls (P = .01). CONCLUSION: There is an anti-CV-B4 activity in saliva of patients with type 1 diabetes that may be a useful marker to study the role of CV-B in the pathogenesis of the disease.

RESUMO

La maladie de Davies ou Fibrose Endomyocardique Constrictive (FEMC) est une cardiomyopathie restrictive d'étiologie inconnue. Objectif : Montrer l'intérêt incontournable de l'échocardiographie trans-thoracique bidimensionnelle comme technique non-invasive référentielle dans le diagnostic et dans le suivi de la FEMC dans notre contexte de travail. Les auteurs présentent l'observation d'un adulte jeune de 22 ans qui habitait une zone forestière. Il avait comme antécédents une tuberculose osseuse et de régulières piqûres de moucherons. Il consultait pour une insuffisance cardiaque globale à prédominance droite évoluant depuis 3 semaines. L'examen clinique retrouvait une altération de l'état général, une cyphoscoliose dorsale, une tachycardie à 100 battements par minute, des souffles d'insuffisance mitro-tricuspidienne, des râles sous-crépitants à la base pulmonaire droite, des signes de défaillance cardiaque droite et une tension artérielle à 110/80 mm Hg. La radiographie thoracique montrait une volumineuse cardiomégalie aux dépens des oreillettes, une dilatation des artères pulmonaires et une cyphoscoliose dorsale.L'électrocardiogramme en rythme sinusal montrait un bloc bi-fasciculaire, une hypertrophie auriculaire gauche et un trouble non-spécifique de la repolarisation de ST. L'hémogramme révélait une hyper éosinophilie à 1500 éléments/mm3, une créatininémie à 148 µmol/l avec une clairance de la créatine à 65ml/mn. L'échocardiographie trans thoracique bidimensionnelle, après avoir écarté le cœur pulmonaire chronique et de la péricardite chronique constrictive, avait montré les critères majeurs de la maladie de Davies contrairement aux autres techniques de diagnostic disponibles. Le traitement médical est décevant voire palliatif. Conclusion : La maladie de Davies est une fibrose endomyocardique tropicale, d'étiologie inconnue. La défaillance cardiaque est le mode d'expression clinique. L'évolution est marquée par des récidives fréquentes caractérisées par des poussées d'insuffisance cardiaque. L'échocardiographie bidimensionnelle est l'examen référentiel du diagnostic et du suivi de cette affection. Le traitement médical est décevant

RESUMO

La péricardite liquidienne du drépanocytaire homozygote présente des particularités.Objectif : Déterminer les aspects cliniques, biologiques et thérapeutiques de la péricardite liquidienne chez le drépanocytaire homozygote dans notre contexte de travail.Patients et méthode : Il s'est agi d'une étude descriptive, transversale et uni variée réalisée dans le service de cardiologie de l'hôpital général de Loandjili entre avril 2013 et mai 2014 (soit 13 mois) concernant les patients drépanocytaires homozygotes hospitalisés pour une péricardite liquidienne.Résultats : Quatorze patients étaient hospitalisés pour péricardite liquidienne, dont 5 étaient drépanocytaires homozygotes, soit une fréquence relative de 35,7%. L'âge moyen était de 24,2 ± 5 ans avec des extrêmes de 19-30 ans dont 4 hommes et 1 femme. Les douleurs thoraciques étaient chez 5 patients, la dyspnée d'effort chez 5 patients, la fièvre chez 4 patients, la toux sèche chez 1 patient. L'asthénie physique était retrouvée chez 5 patients. La tachycardie régulière et la pâleur conjonctivale étaient chez 5 patients. Un patient présentait un ictère conjonctival. La tension artérielle basse était retrouvée chez 5 patients. Un patient présentait une adénopathie cervicale. L'hépato-splénomégalie était observée chez 2 patients, et un ulcère de jambe existait chez 1 patient. La cardiomégalie était retrouvée chez tous les patients. Le rapport cardio-thoracique moyen était de 73 ± 5,43% avec des extrêmes de 70 à 81%. Tous les patients présentaient une anémie et l'hémoglobine moyenne était de 7,62 &plus 1,94 g/dl avec des extrêmes de 4,3 à 9,3 g/dl. Trois patients présentaient une hyperleucocytose. La leucopénie était chez 1 patient. Un patient était séropositif à VIH. Le test tuberculinique était phlycténulaire chez un patient. Tous les patients avaient un épanchement péricardique. Le diamètre moyen du décollement péricardique était de 36,4 ± 10,31 mm avec des extrêmes de 23,4 à 52,4 mm. Tous les patients avaient reçu un culot globulaire, des anti-inflammatoires non-stéroïdiens, de l'acide folique et des anti-sécrétoires. Un patient était sous antituberculeux. Deux patients étaient sous triple antibiothérapie synergique. Un patient était sous traitement anti-rétroviral. Le traitement anti-comitial était prescrit chez 2 patients. Les étiologies étaient virales, bacillaires et purulente. L'évolution était émaillée de complications mortelles.Conclusion : La péricardite liquidienne chez le drépanocytaire est grave. Les complications hématologiques, neurologiques, digestives et cardiaques majorent la mortalité

RESUMO

The supply and the quality of care dispensed in a service depend on the quality of the technical and human tray, but also from effective presence of the staff during the work time. The purpose of this study is to determine the absenteeism level of the paramedical staff in General Pediatric and Neonatology of Loandjili General Hospital (Pointe Noire) and identifying causes. A cross-sectional study has been conducted from January 1(st) to June 30(th) 2011 on 21 nurses in General Pediatric and 20 in Neonatology. The absenteeism level was obtained by the link of the number of missing days out of the number of the work days x 100. The absence was justified when it relieved from a reason informed by the administrative texts of the firm; and authorized when it requested the authorization of the administration of the firm. In total, 370 absences have been unregistered, the average absenteeism level was of 8.4%. The absence was justified in 242 cases (65.4%) and authorized in 178 cases (48.1%) which 84 times in writing and 94 times verbally. When the absence was justified, it was the fact of the disease of a member of the family in 82 cases, of the death or the burial of a member of the family in 81 cases, of the agent disease, 84 cases, or other reasons in the remains of cases. The absence occurred between 7 a.m. and 14 p.m. in 57.3%, 14 p.m. and 7 p.m.in, 25.7% and between 7 p.m. and 7 a.m. in 17.0%. The absenteeism was mainly observed (85.7%) for the nurses of about 30 years old and those (59.5%) whom the seniority in the service was inferior or equal 5 years. The absences justified were more observed (p< 10(-4)) for nurses of about 30 years old and those whom the seniority did not pass 5 years. The absenteeism of nurses constitutes a real social and administrative problem that deserves a particular attention considering its impact on the supply and the quality of cares.

RESUMO

BACKGROUND: High-risk HPV (HR-HPV) are associated with the development of cervical cancer, the most common cancer in women in developing countries. Reliable diagnosis of HR-HPV infection combined with simple procedures to collect and store biological samples, could improve primary screening programs and vaccine strategies in these areas. OBJECTIVE: To evaluate HR-HPV detection in conventional and dried samples. STUDY DESIGN: The presence of HR-HPV in 31 women in Republic of Congo (Central Africa) has been investigated by using standard cervical samples and dried cervical samples collected on filter paper and vaginal tampons. The detection of HPV DNA was performed in the Laboratory of virology in Lille (France) by using Hybrid capture 2 and HPV 16/18/45 Probe Set Test. RESULTS: 22 standard samples were found positive for the detection of HR-HPV (71%). HPV 16/18/45 was displayed in 15 out of 22 samples positive for HR-HPV (68%). The correlations between HPV detection by using standard samples and samples dried on filter paper and dried tampons were 90.3% (kappa = 0.77) and 80.6% (kappa = 0.5) respectively. The sensitivity and the specificity of HPV detection reached 91% and 89%, respectively, with samples dried on filter paper and were 86% and 67%, respectively, for dried tampons compared with standard samples. CONCLUSION: Dried cervical samples and dried vaginal tampons can represent an alternative to conventional sampling to reduce barriers to large screening programs in developing countries and to facilitate storage and transport to reference centers.

RESUMO

The role of enteroviruses in type 1 diabetes has long been suspected. A lower risk of type 1 diabetes is associated with breastfeeding, which could be due to a protective effect against enteroviruses. The neutralizing activity of breast milk against CVB4, a representative of enteroviruses was investigated in this study in vitro. Breast milk was cytotoxic to Hep-2 cells up to a dilution of 1/32, whereas the aqueous fraction obtained after centrifugation was not cytotoxic; although it inhibited the cytopathic effect of CVB4 on Hep-2 cell monolayers. The anti-CVB4 neutralizing activity of aqueous fractions of breast milk from 49 donors living in Northern France and 15 donors living in Congo, where enteroviral infections are more prevalent, were determined. The levels of colostrum activity expressed as titre ranged from <2 to 32 in 36% of the donors from France whereas they were >128 in every donor from Congo. Pasteurized colostrum had a lower anti-CVB4 activity compared to fresh samples (P < 0.0001, n = 49). The treatment of colostrum samples with jacalin-coated beads that bind specifically to human IgA, showed that IgA plays a role in anti-CVB4 activity. There was no correlation between the neutralizing activities of breast milk and serum (P = 0.37, n = 25). The current study showed that the variations in anti-CVB4 activity in breast milk can be attributed to environmental and living conditions. Whether a low protective activity of breast milk against enteroviruses expose newborns to a higher risk of type 1 diabetes deserves further investigation.

RESUMO

The purpose of this study was to determine the cytological profile and risk factors for intraepithelial precancerous lesions of the uterine cervix in an urban community of Pointe-Noire, an industrialized seaport located in the southeast region of Congo-Brazzaville. A transverse study was carried out over a period of 18 months (January 2003 to July 2004) in the Center for the Study of Human and Animal Diseases (CSHAD) at the General Adolphe Sie Hospital in Pointe-Noire. A total of 1347 files of women benefiting from cervico-vaginal smears were included in the study. Testing was undertaken either at the request of the patient (voluntary screening) or at the request of a health care provider (physician, midwife or nurse) in relation with various gynecological problems. The relative frequency of intraepithelial lesions was estimated to be 15.36% including 9.17% of low-grade intraepithelial lesions (Ig IEL) and 6.19% of high-grade intraepithelial lesions (hg IEL). The mean age of patients with hg IEL was 42.25 years (range, 12 to 17). Study of the interval between actual age at the time of sample collection and age of first sexual relations showed that women presenting IEL had an interval of at least 20 years. This interval probably corresponds to the time necessary for the interaction between human papillomavirus (HPV) and epithelial cells of the uterine cervix to induce intraepithelial lesions that lead to development of cancer of the uterine cervix. Comparative analysis of the number of sexual partners between the group of women with normal smears and the group with smears showing hg IEL indicated a clear predominance of the mean number of partners in the latter group, i.e., 2 +/- 1,2 versus 5 +/- 1,8 (p < 0.05). Most IEL were observed in multigestational women who accounted for 75.39% with a mean of 6.21 for hg IEL. This preliminary study provides a sound factual basis in terms of epidemiological data on these precancerous lesions of the uterine cervix in the Kouilou department of Congo-Brazzaville. These data will serve as benchmarks and guidance for forthcoming screening campaigns for early detection of uterine cervix cancer.

RESUMO

INTRODUCTION: Pulmonary infestation with Strongyloides stercoralis is an exceptionally rare cause of haemoptysis, the diagnosis being difficult and often delayed. CASE REPORT: We report the case of a retired coal miner suffering from pneumoconiosis who presented with acute respiratory insufficiency and massive haemoptysis, with a fatal outcome, associated with pulmonary stongyloidosis. The only identified source of infestation with Strongyloides stercoralis was his period in the coal mine and the only risk factors for the hyperinfestation were a short course of systemic corticosteroid therapy and the presence of a peritoneal-auricular valve. CONCLUSION: This observation illustrates the importance of a systematic search for anguillosis in ex coal miners prior to any immunosuppressant treatment in order to avoid the serious and frequently fatal form of hyperinfestation with Strongyloides stercoralis.

RESUMO

Solitary fibrous tumor is a rare circumscribed neoplasm involving usually the pleura and now described in many organs and in the soft tissues with a favorable outcome when completely excised. We report herein a malignant solitary fibrous tumor of the pleura occurring in a 59-year-old woman. The tumor cells strongly expressed vimentin and CD 34. In addition a weak positive staining was obtained using CD 99 and bcl 2. A disconcerting focal immunoreactivity with cytokeratin was observed. Solitary fibrous tumor is composed of loosely arranged spindle cells of variable density and may occasionally mimic malignant mesothelioma, an hemangiopericytoma or synovial sarcoma. Immunohistochemical study is helpful demonstrating a strong positivity for vimentin and CD 34 and absence of staining for epithelial markers and S-100 protein.

RESUMO

BACKGROUND AND AIM OF THE STUDY: Cardiac papillary fibroelastoma (CPF) is a rare and histologically benign tumor, but may have a malignant propensity for life-threatening complications; thus, surgical removal is justified. Case histories were reviewed of four patients who underwent surgical management after diagnosis of CPF located on aortic (n = 2) or mitral (n = 2) valves. Our aim was to provide explanations for the clinical diversity of the lesions and, using histological and immunohistochemical methods, to hypothesize the genesis of these tumors. METHODS: Among four patients with a diagnosis of valvular CPF, two had previous and recent history of neurological embolic symptoms with small echographically located tumors attached to the ventricular side of aortic cusps. Two other patients (one with paroxysmal atrial fibrillation, one with no neurological or rhythmically related stroke) had CPFs located on the posterior or anterior mitral leaflets. RESULTS: Surgical excision was performed with a conservative valve-sparing approach. Histological and specific immunohistochemical (IHC) studies were conducted on all samples. The postoperative course was uneventful, and histological analysis confirmed the diagnosis of CPF with typical fronds characterized by three successive layers. In the first two patients there was correlation between neurological events and the presence of thrombus aggregated on the injured superficial endothelial layer. In the other patients, no endothelial damage or thrombus was found. IHC studies showed dysfunction of the superficial endothelium, a centrifugal mesenchymal cellular migration arising from the central layer to the superficial layer with differentiation steps, the presence of dendritic cells in the intermediate layer, and remnants of cytomegalovirus (CMV) in the intermediate layer. CONCLUSION: Despite their benign histological aspect, and independent of their size, CPFs justify surgical excision because of their high potential to systemic embolization. In most cases, valve sparing management is possible with no observed recurrence after complete excision. The presence of dendritic cells and CMV strongly suggests the possibility of a virus-induced tumor, therefore evoking the concept of a chronic form of viral endocarditis.

RESUMO

Primary neuroendocrine carcinomas of the kidney are infrequent. The large cell neuroendocrine carcinoma is a subtype with an aggressive course and a worse prognosis. We report two cases, a 35-year-old man and a 75-year-old woman who died within 6 and 5-months after surgery despite radical nephrectomy and chemotherapy. Histological and immunohistochemical features are presented.

RESUMO

To investigate enterovirus replication versus persistence in end-stage cardiac diseases, endomyocardial biopsies from explanted hearts of 70 patients with idiopathic dilated cardiomyopathy (IDCM), 64 patients with chronic coronary disease (CCD), and 45 donors of healthy hearts (controls) were examined by reverse transcriptase-polymerase chain reaction for genomic and antigenomic enterovirus RNA and by VP1 antigen immunohistochemistry. Enterovirus genome was detected in 25 of 70 patients with IDCM and in 21 of 64 patients with CCDs (35.7 vs. 32.8%, respectively; P=.12). Of the 46 patients positive for genomic RNA, only 3 exhibited antigenomic RNA and VP1 antigen that demonstrated active viral replication, whereas 43 had latent infection characterized by the absence of antigenomic RNA associated with or not with VP1 antigen expression. No viral component was detected in control subjects. The findings demonstrate that a small percentage of patients with end-stage chronic cardiac diseases had active enterovirus replication in their myocardium.

RESUMO

We describe a juvenile granulosa cell tumor expressed by an early pseudopuberty occurring in a 3-year-old black child. Clinically, an endocrine syndrome was associated with a pelvic mass and ascites. Hyperoestrogenia and serum alphafetoprotein level were biologically detected. Histological examination showed typical microscopic features of a granulosa cell tumor. The patient is well four years after surgery. Growth and mental development are normal.
