Prevalence and Management of Spermatic Cord Torsion (SCT): A Five-Year Review in Souro Sanou University Hospital of Bobo-Dioulasso (Burkina Faso).

Introduction: Spermatic cord torsion (SCT) is a rare urological emergency that can jeopardize the fertility of the patient. Our study aimed to investigate the epidemiological, diagnostic and therapeutic aspects of SCT in Souro Sanou University Teaching Hospital. Materials and Methods: This was a descriptive cross-sectional study with retrospective data collection from January 1, 2017, to December 31, 2021, in the emergency surgical and urology division of Souro Sanou University Hospital. Results: The annual frequency of SCT was 4.4 patients/year. The mean age of the patients was 17.82 ± 6.74 years. Painful swelling of the hemi-scrotum was the main presenting symptom. The torsion involved the left spermatic cord in 50% of cases and both spermatic cords in 5% of cases. The mean time of symptoms before presentation was 78.8 hours ± 153 hours. Only 27.3% of patients presented before the 6th hour after the onset of pain. The average time from presentation to surgical intervention was 5.6 hours ± 5 hours. Orchiectomy was performed in 11 patients (47.8%). The average hospital stay was 3.1 ± 1.4 days. Conclusion: SCT is a rare urological emergency. The prognosis depends on the duration and degree of torsion. A high orchidectomy rate can be observed with a delay in presentation.

[Diabetes mellitus and high blood pressure over risk in HIV-infected people followed at Souro Sanou University Hospital Day Hospital, Bobo-Dioulasso 2018]. / Sur-risque de diabète sucré et d'hypertension artérielle chez les personnes infectées par le VIH suivies à l'hôpital de jour du CHU Souro Sanou, Bobo-Dioulasso, Burkina Faso, 2018.

BACKGROUND: Non-communicable diseases (NCDs) represent the leading causes of death worldwide. HIV also increases the risk of developing NCDs including diabetes mellitus and hypertension. METHODS: A cross-sectional study, based on an analysis of the cohort database of the day hospital of the Souro Sanou teaching hospital in Bobo-Dioulasso (Burkina Faso). Diabetes mellitus was defined by the undergoing of anti-diabetic treatment or two successive measurements of fasting blood sugar above 7mmol/l and high blood pressure by the undergoing of antihypertensive treatment or two successive measurements of blood pressure above 140/90mmHg. Comparison of the frequency of diabetes and hypertension in the people living with HIV/AIDS (PLWHA) population on antiretroviral therapy (ART) with that of the general population of Burkina Faso was made by indirect standardization according to age and gender. RESULTS: A total of 4259 patients including 3148 women (73.9%) were included in this study. The median age of the patients was 45 years (IQR: 38-52); the median body mass index (BMI) was 19.6kg/m2 (IQR: 15.4 - 22.7) and 48.3% of patients had a BMI≥25kg/m2. The median CD4 count was 590 cells/mm3 (IQR: 417-785). The median ART duration was 8.2 years (IQR: 4.7-11.2). The majority of patients (82.9%) were on treatment combinations consisting in 2 INTI+1 NNRTI. Prevalence of hypertension was 39.8%; it was statistically higher in men than in women (45.8% versus 37.8%). Prevalence of hypertension was 87.0% higher in the PLWHA population than among same-sex and same-age subjects in the general population. Prevalence of diabetes mellitus was 7.3%. Diabetes mellitus was more common in men than in women (10.1% versus 6.3%; P<10-3). Prevalence of diabetes mellitus was 36.0% higher in the PLWHA population than among same-sex and same-age subjects in the general population. CONCLUSION: Prevalence of diabetes mellitus and hypertension was higher among PLHWA undergoing ART than in the general population. Care for the PLHWA population should more widely include NCD treatment.

Les gangrènes des organes génitaux externes masculins. Aspects épidémiologiques et thérapeutiques

Objectif : Décrire les aspects épidémiologiques et thérapeutiques des gangrènes des organes génitaux externes masculins. Matériel et méthodes : Il s'est agi d'une étude descriptive et descriptive sur une période de 5 ans allant du 1er janvier 2007 au 31 décembre 2011 au cours de laquelle nous avons enregistré 47 cas de gangrènes des organes génitaux externes. Nous avons analysé rétrospectivement les 39 dossiers qui étaient complets et exploitables. Résultats : Les gangrènes des organes génitaux externes étaient relativement peu fréquentes, constituaient 3,25% des urgences urologiques. Elles étaient l'apanage du sujet d'âge mur avec un âge moyen de 50,17 ans, tous de sexe masculin. Les patients provenaient majoritairement du milieu rural avec 56,4%. Le délai de consultation était assez long avec une moyenne de 9,69 jours avec des extrêmes de 2 jours et 30 jours. Les facteurs de comorbidité ont été retrouvés chez 46,11% des patients. L'origine cutanée a été retrouvée dans 48,7% des patients. Les prélèvements bactériologiques effectués chez 23 patients ont retrouvé un germe chez 13 patients et avec E. coli comme principal germe (10 cas) et accessoirement Staphylococcus aureus (1 cas), Klebsiella pneumoniae (1 cas) et Proteus mirabilis (1 cas). Au plan de la prise en charge tous les patients ont bénéficié d'un traitement médicochirurgical précédé d'une réanimation médicale. Un débridement large avec nécrosectomie a été réalisé chez tous les patients associé à une triple antibiothérapie d'abord probabiliste puis ajustée en fonction du résultat de l'antibiogramme lorsqu'un germe a été identifié. Tous les patients ont subi une cicatrisation dirigée et une plastie de recouvrement a été réalisée. La gangrène des organes génitaux externes reste une affection grave souvent invalidante avec un long séjour hospitalier. Le taux de mortalité était de 17,95%. Conclusion : Les gangrènes des organes génitaux externes masculins sont assez graves avec un fort taux de mortalité. Elles sont relativement peu fréquentes dans notre contexte et la prise en charge est médico-chirurgicale et doit être multidisciplinaire pour espérer obtenir des résultats satisfaisants

[Immuno-virologic dissociation in patients infected by HIV-1 under antiretroviral treatment at the Day hospital of Bobo-Dioulasso from 2008 to 2012 (Burkina Faso)]. / Dissociation immuno-virologique chez les patients infectes par le VIH-1 sous traitement antiretroviral a l'hopital de Jour de Bobo-Dioulasso de 2008 a 2012 (Burkina Faso).

OBJECTIVE: describe the sociodemographic, clinical, therapeutic, biological profile and the observance of treatment in cases of immuno-virologic dissociation response (IVDR) in HIV-1 patients at te 12 months of antiretroviral treatment (ARVT). METHODS: This was a historical cohort study with a descriptive and analytical focus from January 2008 to December 2012; covering the IVDR cases at the day hospital of Bobo Dioulasso. We collected the data during medical consultations by means of the ESOPE software and from medical records of the patients. RESULTS: Of 2078 patients on ARVT, 84 or 4% presented one IVDR, among which 56 women (66.7%) and 28 men (33.3%). The average age was 45 years [range: 45-55 years]. At the initiation of ARVT, most patients were in clinical stage 3 or 4 of the WHO classification (57.1%). The body mass index (BMI) average was 20.5kg/m2 [IQR = 18.5 and 23]. The average number of +CD4 T lymphocyte was 42 cells/mm3 [IQR = 12- 63]. During follow-up, the median gain in BMI was 3.2 kg/m2 [IQR = 1.2 to 4.3 kg/m2], the median gain was 76 cells/µl [IQR = 60 - 88]. The viral plasmatic load of the HIV-1 was undetectable with a rate of TCD4+ < 100 cells /µl in 12 months. Factors associated with IVDR were the age between 35 and 45 years (p = 0.0009), the number of +CD4 T cells (+CD4T≤50) at initiation of ARVT (p = 0.00045 ) and the WHO classification clinical stage 3. CONCLUSION: This study demonstrates the problem of IVDR management in Bobo-Dioulasso and reminds of the interest of care follow-up of people living with HIV-1 by viral load and not only by the rate of CD4+ T especially in the decentralized structures of coverage of HIV, where changes of therapeutic mechanisms operate disjointedly.

OBJECTIF: décrire le profil sociodémographique, clinique, thérapeutique, biologique et l'observance du traitement des cas de réponse immuno-virologique dissociée (DIV) chez les patients VIH-1 à 12 mois de traitement antirétroviral (ARV). MÉTHODES: Il s'agissait d'une étude de cohorte historique à visée descriptive et analytique de janvier 2008 à décembre 2012, portant sur les DIV suivis à l'hôpital de jour (HDJ) de Bobo- Dioulasso. Nous avons recueilli les données au cours des consultations médicales à l'aide du logiciel ESOPE et à partir du dossier médical des patients. RÉSULTATS: Sur 2078 patients sous ARV, 84 soit 4% présentaient une dissociation immuno-virologique (DIV), dont 56 femmes (66,7%) et 28 hommes (33,3%). L'âge médian était de 45 ans [EIQ = 45­ 55 ans]. A l'initiation du traitement ARV, la plupart des patients étaient aux stades cliniques 3 ou 4 de l'OMS (57,1%). La médiane de l'IMC était à 20,5kg/m2 [EIQ=18,5 et 23 ans]. La médiane du nombre de lymphocyte TCD4+ était de 42 cellules/mm3 [EIQ= 12­ 63]. Au cours du suivi, le gain médian en indice de masse corporelle était de 3,2 kg/m2 [EIQ=1,2­4,3 kg/m2], le gain médian en TCD4+ était de 76 cellules/µl [EIQ=60 ­ 88]. La charge virale plasmatique du VIH-1 était indétectable chez tous avec un taux de TCD4+ < 100 cellules/µl à 12 mois. Les facteurs associés à la réponse immunovirologique dissociée étaient l'âge compris entre 35 à 45 ans (p = 0,0009), un nombre de lymphocytes T CD4 (CD4≤50) à l'initiation du traitement ARV (p=0,00045) et le stade clinique OMS 3. CONCLUSION: Cette étude prouve la problématique de la gestion de la réponse immuno-virologique dissociée à Bobo-Dioulasso, et rappel tout l'intérêt du suivi des PvVIH par la charge virale et non seulement par le taux de TCD4+ surtout dans les structures déconcentrées de prise en charge du VIH, où des changements de régime thérapeutique s'opèrent à tord.

[Initial results of adjustable periurethral balloons (ACT™ and pro ACT™) in the treatment of adult stress urinary incontinence with intrinsic sphincter deficiency]. / Résultats initiaux de l'utilisation des ballons périurétraux ajustables (ACT™ et pro ACT™) dans le traitement de l'incontinence urinaire d'effort par insuffisance sphinctérienne de l'adulte.

OBJECTIVE: To report efficacy and morbidity of periurethral adjustable balloons (PUAB) in the treatment of stress urinary incontinence (SUI) with intrinsic sphincter deficiency (ISD). PATIENTS AND METHODS: Retrospective descriptive and analytic patients cohort study was performed from July 2010 to June 2012. We reviewed data from 43 patients (19 women and 24 men). The patients were categorized into 3 groups: i) women, ii) men after prostatectomy, iii) men with neurogenic SUI (prostate in position). Sandvick score and the average of 3 days 24 h Pad test evaluated the efficacy of the device. The patients impression of improvement was assessed in three degrees: completely improved, partially improved, not improved. RESULTS: After a median follow-up of 67 weeks (min. 40, max. 91) a significant improvement of the score of Sandvik was observed (8 to 4, P<0.005). The proportion of dry patients or with one security protection in the three groups was 57.9%, 64.3% and 50% respectively for women, men after prostatectomy, and men with neurological SUI. About 27.9% (12/43) of the patients had post-operative complications. These complications required an explantation of the PUAB in 11/12 patients among whom 7/11 (63.6%) had a delayed re-implantation of the device. CONCLUSION: In this series, the overall efficacy observed was 67.4% with a post-operative complication rate of 27.9%. The device adjustment was done in consultation as well as the complications management and the explantation when necessary. LEVEL OF EVIDENCE: 4.

[Epidemiology, etiology and psychosocial impact of urogenital fistulas in a cohort of 170 consecutive patients managed in three treatment centers in Burkina Faso from 2010 to 2012]. / Aspects épidémiologiques, étiologiques et impact psychosocial des fistules urogénitales dans une cohorte de 170 patientes consécutives, prises en charge dans trois centres du Burkina Faso de 2010 à 2012.

OBJECTIVE: To describe the socio-demographical aspects, etiologies and psychosocial consequences of urogenital fistula patients (UGF) in Burkina Faso (BF). PATIENTS AND METHODS: Descriptive study of a cohort of consecutive patients during a period of 18 months (December 1st 2010 to August 31st 2012) in three centers of treatment in BF. Each patient has had a standardized complete medical observation focused on sociodemographics, clinical finding, past medical history and etiologies of UGF. Some patients had an interview with a psychologist. RESULTS: One hundred and seventy patients with mean age 35 years (minimum: 16, maximum: 70) were enrolled during the study period. The majority of patients were housewives (90.5%, n=152) and illiterates (92.9%, n=158). Among the patients, 62.4% (n=106) lived in rural zones. Obstetrical fistula was the most common cause of UGF (87.6%, n=149) in our study and prolonged labor occurred in 93.3% (n=139) of cases with 17.5% (n=26) who delivered at home. The majority of our cases were vesico-vaginal fistula (70.6%, n=120). Fifty-five patients (32.4%) were divorced after the fistula. The sensation of humiliation and sadness were noted at all the patients who had a psychological evaluation and 87.5% (n=14) of them have had suicidal ideas. CONCLUSION: The UGF are frequent in Burkina Faso and obstetrical etiology is dominant. The physical and psychosocial repercussions are important for the women victims of this pathology. LEVEL OF EVIDENCE: 4.

[Sensitivity to change of the USP score (Urinary Symptoms Profile) after surgical treatment of benign prostatic hyperplasia (BPH)]. / Sensibilité au changement du score USP (Urinary Symptoms Profile) après traitement chirurgical de l'hypertrophie bénigne de la prostate (HBP).

OBJECTIVE: To evaluate the sensitivity to change in USP score (Urinary Symptoms Profile) after surgical treatment of benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: Prospective study collecting IPSS (International Prostatic Symptom Score) and USP scores before and 6 weeks after surgery for BPH. Sensitivity to change was assessed using effect size (ES) and mean standardized response (MSR). RESULTS: Thirty patients, mean age of 68±10 years (min: 52, max: 90) were included in this study. The mean IPSS and USP scores were 14.3 (e.t.: 5.42), 20.3 (e.t.: 5.22) and 3.53 (e.t.: 3.68), 3.43 (e.t.: 3.48) before and after surgery respectively. The overall USP score showed excellent sensitivity to change with a global value of ES and MSR of 1.986 and 2.322 respectively. CONCLUSION: The USP score has an excellent sensitivity to change. It seems to be a valid and reliable score that can be perfectly adapted to the assessment of symptoms associated with BPH, with good sensitivity to changes in the overall score, with the advantage over the IPSS of an exhaustive exploration of all urinary symptoms particularly in the field of urge urinary incontinence and stress urinary incontinence. LEVEL OF PROOF: 4.

[Epidemiology of a cohort of 450 urolithiasis at the Yalgado Ouédraogo university hospital of Ouagadougou (Burkina Faso)]. / Épidémiologie d'une cohorte de 450 lithiasesurinaires au CHU Yalgado Ouédraogo deOuagadougou (Burkina Faso).

OBJECTIVE: To report the epidemiological and diagnosis characteristics of urolithiasis in the city of Ouagadougou (Burkina Faso). PATIENTS AND METHODS: We performed a retrospective and descriptive study of a cohort of urolithiasis patients from January 2009 to December 2011 at the department of urology of the Yalgado Ouédraogo University hospital of Ouagadougou. The minimum required data were: age, gender, occupation, residence, complete medical observation and medical imaging results. RESULTS: Four hundred and fifty patients with a median age of 35 years were included in this study. Urinary stones prevalence was 12.5%. There was a male predominance with a sex ratio of 1.91. Renal colic found in 32% of patients was the main pattern of consultation. Urinary schistosomiasis was the main etiological factor correlated with the occurrence of urolithiasis (P < 0.05). The majority of urinary stones in this study were located in the upper urinary tract (86.5%). Complications were dominated by urinary tract infections (45.2%) and obstructive renal failure (8.9%). CONCLUSION: The characteristics of urolithiasis in our center were similar to those reported in the developing world but seem to evolve toward those of industrialized countries.

[Efficacy and tolerability of antiretroviral therapy containing tenofovir disoproxil fumarate-emtricitabine-efavirenz in treatment-naive patients infected with HIV-1 in Bobo Dioulasso (Burkina Faso, 2009-2011)]. / Efficacité et tolérance d'une trithérapie antirétrovirale à base de ténofovir disoproxil-emtricitabine-éfavirenz chez les patients naïfs infectés par le VIH-1 à Bobo Dioulasso (Burkina Faso, 2009-2011).

The objective of this study was to evaluate the effectiveness and the clinical tolerance of a combination containing TDF/FTC/EFV in the treatment of HIV infection. This was a retrospective and descriptive study which included 196 adults infected by HIV-1 and treated by a combination containing TDF/FTC/EFV during 29 months in the daily hospital of Bobo Dioulasso. The median duration of follow-up was 7 months IQR [5-14 month]. The median age was 37 years IQR [31-45].With the initiation of treatment ARV, the median of the index of body mass was of 19 IQR [17-22]. The median of the lymphocytes TCD4 was 201/µl IQR [74-298/µl]. During the follow-up, we reported 25 deaths (12.8%). HIV-1 RNA plasma viral load was undetectable in 91.9% of the patients (124/135) at six months of treatment. The majority of the adverse effects of the treatment were of a neurosensory nature (40.5%). The TDF/FTC/EFV combination showed a good effectiveness in the treatment of the infection with HIV-1 in the first intention just as a good clinical tolerance.

[Transcutaneous tibial nerve stimulation in the overactive bladder syndrome in patients with Parkinson's syndromes]. / Stimulation transcutanée chronique du nerf tibial dans l'hyperactivité vésicale des syndromes parkinsoniens.

OBJECTIVES: To evaluate the efficacy of chronic transcutaneous tibial nerve stimulation (TNS) on overactive bladder syndrome in female patients with Parkinson's disease (PD) and multiple system atrophy (MSA). PATIENTS AND METHODS: A prospective monocentric study enrolled six female patients with PD or MSA suffering from overactive bladder syndrome for a six-week study period. Daily sessions of 20 minutes of TNS were provided. The primary outcome measurement was the Patient Global Impression of Improvement (PGI-I scale). The secondary outcomes measurements were symptom and quality of life scores, bladder diary and urodynamics. The outcomes after 6 weeks of TNS were compared to baseline. RESULTS: TNS was considered as an effective treatment by five patients out of six (83%) who ask to pursue the treatment and were still doing it 6 months after the end of the study. A trend improvement was observed in only two of the secondary evaluation criteria the V8 median score 21/40 to 14/40 (P=0.2) and the maximum cystometric capacity increased from 211 mL ± 106 to 260 mL ± 226 (P=0.6) after SNT. CONCLUSION: Although urodynamics and symptoms scores did not show significant difference, an efficacy of TNS on overactive bladder in PD and MSA is possible. Additional placebo controlled works enrolling more patients are required to ensure these preliminary results.

[Bladder-sphincter disorders associated with Wolfram syndrome]. / Troubles vésicosphinctériens au cours du syndrome de Wolfram.

OBJECTIVES: To identify and describe functional urinary symptoms, uro-nephrological complications and their impact on quality of life in a cohort of patients diagnosed with the Wolfram syndrome (SW). PATIENTS AND METHODS: A transversal descriptive patient's cohort study was performed. The Urinary Symptom Profile (USP) and the International Consultation Incontinence Questionnaire - Female Lower Urinary Tracts Symptoms (ICIQ-FLUTS) were used to evaluate urinary symptoms and their impact on quality of life through direct interviews conducted by telephone. A less than 6-month old renal ultrasound and serum creatinine results were asked to the patient or physician. RESULTS: Thirty-three patients have been contacted and 22 (73%) agreed to participate in this study. Eighteen patients over 22 had spontaneous micturition when four of them had an urinary diversion (two definitive, two temporaries) before being included in this study. Seventy-three percent of patients with spontaneous micturition had urinary symptoms. A severe or moderate symptoms score was noted in 67% (12/18 patients) and 11% (2/18 patients) respectively. CONCLUSION: Functional urinary dysfunctions were frequent and impacted quality of life in more than one half of patients diagnosed with SW in this study. Early diagnostic and regular urological follow-up can improve the quality of life and prevent severe urinary complications.

[Anderson-Hynes open pyeloplasty: which indications in the area of laparoscopic surgery?]. / La pyéloplastie à ciel ouvert selon Anderson-Hynes : quelles indications devant le développement de la laparoscopie ?

OBJECTIVES: To evaluate the results of Anderson-Hynes open pyeloplasty in our institution. And then to compare them to those of laparoscopic procedure and identify what can be considered now as the indications of the open procedure. PATIENTS AND METHODS: It was a retrospective study on 30 cases of ureteropelvic junction syndrome managed by Anderson-Hynes open procedure. The clinical, biological and radiologic characteristics of the patients as well as the surgical technique and its results were taken into account. The patients were classified, according to Valdeyer and Cendron classification as type II in eight cases (26.7%), type III in ten cases (33.3%) and type IV in four cases (13.3%). There were also eight cases of giant hydronephrosis (26.7%). The operating time, the length of hospital stay and the outcomes were studied and compared with those of the laparoscopic pyeloplasty found in the medical literature. RESULTS: The mean operating time was 115 ± 33.4 minutes (90-230 min). The mean length of hospital stay was 10.4 ± 5.1 days. Six patients (20%) had postoperative complications. After a mean follow-up of 28 ± 13.7 months (13-48 months), our first-hand success rate was 90% (n=27). CONCLUSION: Anderson-Hynes open pyeloplasty reached good results but nowadays its indications can be limited to laparoscopic contraindications, severe hydronephrosis (grade IV or giant hydronephrosis) and second-hand cases. The two latter indications depend on the surgeon experience in laparoscopic surgery.

[Extraparenchymental distribution and feasibility of selective clamping of segmental renal arteries during partial nephrectomy: a study of the dissection of 30 kidneys from recent nonformolised corpses]. / Distribution extraparenchymateuse et accessibilité au clampage sélectif des artères rénales segmentaires au cours de la néphrectomie partielle : à propos de la dissection de 30 reins de cadavres frais non formolés.

OBJECTIVE: To assess the feasibility of selective clamping of segmental renal arteries during partial nephrectomy, in order to limit renal infarction to the pathological area to be resected. MATERIALS AND METHODS: A dissection of renal artery and its extraparenchymal branches was realised. The study included 30 kidneys from recent nonformolised corpses. The size, distribution, and accessibility of the arteries were considered. All the corpses underwent a lombotomy with or without rib resection. RESULTS: The majority of dissected kidneys had a unique artery (96.66% of cases). The number of segmental arteries was zero in five cases (16.66%), one in four cases (13.33%), two in four cases (13.33%), three in one case (3%), four in 15 cases (50%) and five in five cases (16.66%). The posterior and inferior segmental arteries were more accessible to isolate with a respective ratio of 94 and 100% at segmental level. Apical and middle segmental arteries were least accessible with a respective ratio of 73 and 80%. The majority of accidents during dissection occurred with the middle segmental artery (62.5% of vascular lesions). CONCLUSION: This anatomic dissection on corpses showed that selective renal segmental arteries is possible in the majority of cases. This dissection is better indicated in partial nephrectomies for renal tumours located posteriorly or in the lower pole.

[Complications of transrectal prostate biopsy]. / Complications de la biopsie prostatique transrectale.

OBJECTIVES: The aim of this study was to report the transrectal prostate biopsy complications, to identify the factors involved in their occurring and to insist on their prevention. PATIENTS AND METHODOLOGY: It is a prospective study interested on patients managed in the urological and andrological service in Aristide le Dantec Hospital in Dakar for prostate tumour from February 2002 to March 2004 and in whom the indication of prostate biopsy was performed. All the patients fulfilling the including criteria were taken in care according to a same protocol that was a transrectal sextant biopsy This act was performed under preventive antibiotherapy based on fluoroquinolones started one day before and going on three days after biopsy associated to a rectal preparation performed the same day of biopsy At the end of the biopsy the patient was managed externally during three days after biopsy Following parameters were studied: age of patients, the histopathological results and the post operative complications. RESULTS: Two hundred and four (204) biopsies were performed. The median age of the patients was 69.1 years with the extremes of 42 years and 93 years. The global rate of complications was 13.5% with a majority of bleeding. There no major complication registered. Rectal and urethral bleeding was over in 24 hours. The complete urine retention was under the form of a unique happening complication. The distribution of complications according to the results of the biopsy did not reveal any particularity. CONCLUSION: The rectal preparation associated to preventive antibiotherapy seems to reduce infectious complications.
