RESUMEN

INTRODUCTION: Obesity is a complex, multifactorial disease caused by various factors. Recently, the role of the gut microbiota in the development of obesity and its complications has attracted increasing interest. PURPOSE: This article focuses on the mechanisms by which gut microbiota dysbiosis induces insulin resistance, type 2 diabetes, and cardiovascular diseases linked to obesity, highlighting the mechanisms explaining the role of gut microbiota dysbiosis-associated inflammation in the onset of these pathologies. METHODS: A systematic study was carried out to understand and summarize the published results on this topic. More than 150 articles were included in this search, including different types of studies, consulted by an online search in English using various electronic search databases and predefined keywords related to the objectives of our study. RESULTS: We have summarized the data from the articles consulted in this search, and we have found a major gut microbiota alteration in obesity, characterized by a specific decrease in butyrate-producing bacteria and the production of metabolites and components that lead to metabolic impairments and affect the progression of various diseases associated with obesity through distinct signaling pathways, including insulin resistance, type 2 diabetes, and cardiovascular diseases (CVD). We have also focused on the major role of inflammation as a link between gut microbiota dysbiosis and obesity-associated metabolic complications by explaining the mechanisms involved. CONCLUSION: Gut microbiota dysbiosis plays a crucial role in the development of various obesity-related metabolic abnormalities, among them type 2 diabetes and CVD, and represents a major challenge for chronic disease prevention and health. Indeed, the intestinal microbiota appears to be a promising target for the nutritional or therapeutic management of these diseases.

RESUMEN

BACKGROUND: While the role of BRCA1/2 genes in familial breast and ovarian cancer is well established, their implication in the sporadic form of both cancers is still controversial. With the development of poly (ADP-ribose) polymerase (PARP) inhibitors, the exact relationship between BRCA1/2 genes and sporadic triple negative breast cancer/high grade serous carcinoma (TNBC/HGSC) needs to be further investigated. Therefore, we conducted a study in which we analyze BRCA1/2 point mutations and copy number alterations in Moroccan patients suffering from TNBC/HGSC. METHODS: To achieve our goal, we analyzed BRCA1/2 genes in the FFPE tissue blocks and blood samples of 65 TNBC/HGSC selected patients, using next generation sequencing technology. RESULTS: From the 65 successfully sequenced patients in our cohort, we detected five-point variants in six different patients, four variants were classified as pathogenic and one of unknown significance. Regarding copy number alterations we detected one copy number loss in BRCA1 gene and one copy number gain in BRCA2 gene. The genetic screening of BRCA1/2 genes using these patients' genomic DNA indicated that five harbored a germline genetic alteration. While three harbored a somatic genetic alteration. To the best of our knowledge, three-point variants detected in our study have never been reported before. CONCLUSION: According to the results found in the present study, in a population without a family history of cancer, the possibility of a BRCA1/2 somatic pathogenic variant in high grade serous carcinoma is 7%. While for Triple negative breast cancer somatic point variants and copy number alterations seems to be a very rare genetic event.

RESUMEN

BACKGROUND: Nasopharyngeal carcinoma is a multifactorial disease mainly affecting the Asian and North African populations including Morocco. This study aimed to determine the epidemiological profile of nasopharyngeal carcinoma in Northern Morocco as well as its clinicopathological, therapeutic, and prognostic characteristics. METHODS: 129 patients with nasopharyngeal carcinoma followed at the regional center of oncology of Tangier in the period between April 2017 and July 2019, and diagnosed elsewhere from March 2000 to February 2019, were included in this study. Statistical analysis of the data was realized using Statistical Package for the Social Sciences (SPSS) software. RESULTS: Nasopharyngeal carcinoma (NPC) represented 5% of all cases with a median age of 50. The most affected age group was 40-54 years (41.1%). Of all patients, 65.9% were men and 34.1% were women with a sex ratio of 1.93 (Male/Female). Undifferentiated nasopharyngeal carcinomas were the most common histological type affecting 96.12% of patients. At diagnosis, the majority of patients (82.2%) had an advanced stage of NPC (III, VIa, b, c) including 5.4% of metastatic cases (IVc). Most cases (86%) had lymph node involvement with cervical mass being the most common clinical presentation. 81.4% of patients received radiotherapy combined with chemotherapy. Among these patients, 54.3% had concurrent radiochemotherapy preceded by induction chemotherapy. The 5-year overall survival (OS) was 86.8% for all patients. It represented 91.3% for early stages, 87.9% for locally advanced stages, and 57.1% for the metastatic stage significantly. The disease-free survival (DFS) at 5 years was 87.6% knowing that relapse occurred in 16 cases. CONCLUSIONS: Nasopharyngeal carcinoma is a particular disease with a late declaration. It is common in Morocco as is the case in other endemic areas with a high prevalence. Patients' survival is significantly influenced by disease staging.

RESUMEN

OBJECTIVE: Intellectual Disability (ID) represents a neuropsychiatric disorder, which its etiopathogenesis remains insufficiently understood. Mutations in the Aristaless Related Homeobox gene (ARX) have been identified to cause syndromic and nonsyndromic (NS-ID). The most recurrent mutation of this gene is a duplication of 24pb, c.428-451dup. Epidemiological and genetic studies about ID in the Moroccan population remain very scarce, and none study is carried out on the ARX gene. This work aimed to study c.428-451dup (24 bp) mutation in the exon 2 of the ARX gene in 118 males' Moroccan patients with milder NS-ID to evaluate if the gene screening is a good tool for identifying NS-ID. RESULTS: Our mutational analysis did not show any dup(24pb) in our patients. This is because based on findings from previous studies that found ARX mutations in 70% of families with NS-ID, and in most cases, 1.5-6.1% of individuals with NS-ID have this duplication. Since 1/118 = 0.0084 (0.84%) is not much different from 1.5%, then it is reasonable that this could a sample size artifact. A complete screening of the entire ARX gene, including the five exons, should be fulfilled. Further investigations are required to confirm these results.

RESUMEN

Intellectual disability (ID), previously called mental retardation, is the most common neurodevelopmental disorder characterized by life-long intellectual and adaptive functioning impairments that have an impact on individuals, families, and society. Its prevalence is estimated to 3% of the general population and its etiology is still insufficiently understood. Besides the involvement of genetic and environmental factors, immunological dysfunctions have been also suggested to contribute to the pathophysiology of ID. Over the years, immune biomarkers related to ID have gained significant attention and researchers have begun to look at possible cytokine profiles in individuals suffered from this disorder. In fact, in addition to playing crucial physiological roles in the majority of normal neurodevelopmental processes, cytokines exert an important role in neuroinflammation under pathological conditions, and interactions between the immune system and central nervous system have long been under investigation. Cytokine levels imbalance has been reported associated with some behavioral characteristics and the onset of some syndromic forms of ID. In this review, we will focus on immunological biomarkers, especially the cytokine profiles that have been identified in people with ID. Thus, data reported and discussed in the present paper may provide additional information to start further studies and to plan strategies for early identification and managing of ID.

RESUMEN

BACKGROUND: To date, the contribution of BRCA1/2 mutations in Moroccan early onset breast cancer patients remains unknown. Here we assess these genetic alterations for the first time in a cohort from North of Morocco. METHODS: Thirty-three patients diagnosed with breast cancer at the age of ≤40 years were recruited irrespective of breast and/or ovarian cancer family history. Coding regions and intron-exon boundaries of BRCA1 and BRCA2 genes were sequenced from peripheral blood DNA using Ion Proton (Thermo Fisher Scientific) next generation sequencing platform. RESULTS: Overall, five BRCA germline mutations were identified (15.1%). The frequency of mutations among patients with family history of breast cancer was 16.7%. Three mutations were found in BRCA1 (9%) and two within the BRCA2 gene (6%). These are three frameshift mutations (c.798_799del, c.2125_2126insA, c.5116_5119delAATA), one missense (c.116G > A) and one nonsense mutation (c.289G > T). The mutation c.5116_5119delAATA has a founder effect in North Africa. Moreover, one variant of unknown significance was identified in BRCA2 (c.4090A > G). Most BRCA mutations carriers (80%) had no family history of breast cancer. CONCLUSION: Our data do not support the hypothesis that BRCA mutations alone explain the higher frequency of breast cancer in Moroccan young women. The young age (≤40 years) for breast cancer diagnosis seems to be strongly predictive of BRCA mutation status in Moroccan patients. These results will help in decision making with regard to genetic counseling and testing in the national scale.

RESUMEN

BACKGROUND: Hereditary breast and ovarian cancer (HBOC) is an autosomal dominant inherited cancer susceptibility disorder. Both BRCA1 and BRCA2 genes are considered as high penetrance genes of this syndrome. The identification of BRCA1/2 genetic alterations before cancer development, grant patients the chance to benefit from various medical cancer prevention approaches. Therefore, the appearance of recent advanced technologies in molecular analysis such as next generation sequencing has simplified full BRCA1/2 analysis. Many attempts took place in hope of understanding the molecular germline spectrum of these two genes in Moroccan HBOC patients. However, most of the past projects focused only on young breast cancer cases, lacked ovarian cancer cases in their cohort and only a limited number of these studies were able to analyze the entire exons or copy number variations for both genes. In attempt of gaining more information regarding the molecular profile of BRCA1/2 in HBOC, we conducted a study in which we analyze their molecular profile on selected Moroccan patients suspected of having HBOC syndrome. METHODS: In this study we obtained blood samples from 64 selected Moroccan patients, who suffered from Breast and/or ovarian cancer and had a strong family history for cancer. To analyze BRCA1/2 punctual variants and copy number variations, we used the Ion Personal Genome Machine (PGM) and Oncomine BRCA1/2 research assay panel. Afterward, we correlated the molecular results with the clinic-pathologic data using IBM SPSS Statistics ver 2. RESULTS: From the 64 selected cases, Forty-six had breast cancer, fifteen had ovarian cancer and three had both breast and ovarian cancer. The molecular analysis revealed that 18 patients from the 64 harbored a pathogenic variant (28%). Twelve had six different BRCA1 pathogenic variants and six had six different BRCA2 pathogenic variants. In this study, we report four pathogenic variants that to the best of our knowledge has never been reported in the Moroccan population before. Regarding copy number variation analysis, No CNV was detected in both genes for all the 64 successfully sequenced and analyzed patients in our cohort. CONCLUSION: Work like the present has an important implication on public health and science. It is critical that molecular profiling studies are performed on underserved and understudied population like Morocco.

RESUMEN

Triple negative breast cancer account for 10% to 20% of all newly diagnosed breast cancer cases, this subtype is well known for its lack of estrogen, progesterone and HER2 expression unlike the other subtypes of breast cancer that usually express at least one of the three. The absence of a specific biomarker for TNBC has made his treatment very challenging and his death rates very high compared to the other subtypes. Therefore, in morocco, many studies have been conducted in the hope of finding a specific biomarker for TNBC, but none of these studies has analyzed the EGFR protein expression and its gene molecular profile and correlated the EGFR analyses results with the genetic profile of other genes. In this study, we analyzed EGFR protein expression and the molecular profile of EGFR, BRCA1, BRCA2 and TP53 genes in 47 TNBC patients. We conducted a retrospective study of 47 Moroccan patients diagnosed with triple negative breast cancer between early 2013 and 2016. In this study, we have analyzed the EGFR. Protein expression, for all the 47 TNBC patients using pharmDx Kit. Then we used the Ion Personal Genome Machine (PGM) and Ion Ampliseq BRCA1/2 panel and hotspot Cancer panel to analyze the molecular profile of BRCA1/2 genes and the hotspot regions of TP53 and EGFR genes. The statistical analysis was performed using IBM SPSS Statistics ver. From the 47 analyzed patients using EGFR pharmDx Kit only 16 (34%) had EGFR overexpression while 31 (66%), patients were normal, moreover, From the 47 TNBC patients, only 39 underwent Mutational analysis of EGFR, BRCA1/2, and TP53 genes. One patient harbored a BRCA1 mutation c.798_799delTT (p.Ser267Lys). While for TP53 gene, 16 patients out of 39 (41%) presented hotspot mutations, seven of them harbored c.743G>A (p.Arg248Gln) mutation, six patients harbored exon 6 mutations from which five harbored the mutation c.659A>G (p.Tyr220Cys) and one the mutation c.817C>T (p.Arg273Cys), and finally, three patients harbored the mutation c.524G>A (p.Arg175His). Regarding BRCA2 and EGFR sequencing results, no mutations or other genetic alterations were detected in 39 patients that were successfully sequenced. Statistical analysis revealed the absence of any correlations.

RESUMEN

Sickle cell disease is one of the most common severe monogenic disorders in the world. The -158 XmnI polymorphism (C>T) of the Gγ-globin gene promoter is known to be associated with increased expression of the Gγ-globin gene, thus, higher production of Hb F and lesser clinical severity. This study aims to determine the frequency of the XmnI polymorphism and its association with Hb F levels as a modulating factor of sickle cell disease severity in north Moroccan patients. Three hundred and eight subjects carrying the sickle cell mutation and 160 healthy individuals were recruited at the regional hospital of Larache, Morocco. The complete blood count and the Hb F levels were analyzed. The XmnI polymorphism was determined by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique and statistical analysis were done using the Statistical Package for Social Sciences software version 20. Our results estimated the allelic frequency of the XmnI polymorphism in our population at 15.8%. Out of 468 samples, 7.6% were homozygous [+/+] and 16.4% were heterozygous [+/-] for the XmnI polymorphism. This polymorphism was revealed at 20.6% in SS patients, 24.2% in AS carriers, 28.6% in Hb S (HBB: c.20A>T)/ß-thalassemia (ß-thal) patients and 22.5% in AA subjects. The north Moroccan sickle cell disease patients have shown a low frequency of the XmnI polymorphism. This was later found to be associated with high Hb F levels and mild clinical severity.

RESUMEN

INTRODUCTION: Obesity is a chronic disease responsible for a high morbidity and mortality rate, with an increasing worldwide prevalence. Obesity is associated with immune responses characterized by chronic systemic inflammation. This article focuses on the mechanisms that explain the proposed link between obesity-associated diseases and inflammation. Also, it describes the role of inflammatory molecules in obesity-associated metabolic abnormalities. METHODS: More than 200 articles were selected and consulted by an online English search using various electronic search databases. Predefined key-words for the pathogenesis of obesity-induced inflammation and associated diseases, as well as the role of various inflammatory molecules, were used. RESULTS: We have summarized the data of the articles consulted in this research and we have found that obesity is associated with a low-grade inflammation resulting from the change of adipose tissue (AT). The AT produces a variety of inflammatory molecules called adipocytokines that are involved in the onset of systemic low-grade inflammation which is the link between obesity and associated-chronic abnormalities; such as insulin resistance, metabolic syndrome, cardiovascular disease (CVD), hypertension, diabetes, and some cancers. Also, we have searched all the inflammatory molecules involved in this pathogenesis and we have briefly described the role of 16 of them which are the most related to obesity-associated inflammation. The results have shown that there are inflammatory molecules that have a positive relationship with the pathogenesis of obesity-related diseases and others have a negative relationship with this pathogenesis. CONCLUSION: Inflammation plays a crucial role in the development of various metabolic-abnormalities related to obesity. In this regard, the management of obesity may help reduce the risk of cardiovascular disease and other metabolic complications by inhibiting inflammatory mechanisms.

RESUMEN

BACKGROUND: Anti-centromere auto-antibodies (ACA) have been described as a marker in Systemic sclerosis (SSc) disease. CENP-B is the major centromere auto-antigen recognized by SSc patients with positive ACA. Our aim was to characterize the major epitope involved in the anti-CENP-B immune response of Moroccan SSc patients. PATIENTS AND METHOD: For identification of SSc biomarkers, 80 sera from patients with SSc and systemic lupus erythematosus (SLE) were screened by indirect immunofluorescence test (IIF) to assess the presence of ANA reactivity. Immunoblotting analysis was performed for 11 sera with positive ACA using the N-terminal and C-terminal region of CENP-B protein as antigens. RESULTS: 29 out of 30 (96, 66 %) patients with SSc had positive ANA. 11 out of 30 (36, 67 %) patients were ACA positive and 6 of them produced auto-antibodies against Nt-CENPB antigen. Two of these 6 Nt-CENPB positive sera produced also other auto-antibodies associated to primary biliary cirrhosis. None of all sera tested showed reactivity against Ct-CENPB. CONCLUSION: Our data showed, for the first time in Morocco, that the Nt-CENPB contains a major epitope for Moroccan SSc patients. These findings could provide additional information that would contribute to improving the diagnosis and management of these patients.

RESUMEN

Objective: Intellectual disability (ID) is a heterogeneous group of disorders characterized by a congenital limitation in intellectual functioning and adaptive behaviour. Our present work aimed to describe the demographic and clinical characteristics in a series of Moroccan individuals with ID living in Fez city and its regions. Design: It was a prospective and descriptive exploratory monocentric study carried out between October 2014 and July 2019. We selected 186 patients diagnosed with ID at three different centers in Fez city. The data were processed and analyzed using the IBM SPSS version 24. Results: Our data revealed a high frequency of male patients with ID (67.2% in male patients vs. 32.8% in female patients). The male-to-female ratio was 2.04. The mean age of our patients was 15.52 ±6.59 years (mean±SD), ranging between 2 and 36 years. The mean age of fathers and mothers at the birth of their child with ID was 36 and 28 years, respectively. Several abnormal behaviors were observed: 23.1 percent delayed language learning, 17.7 percent anxiety, 12.9 percent aggressiveness, 19.18 percent concentration problems, and 5.4 percent hyperactivity. Epileptic seizures were the most common mental health disorder (21.72%) observed in our patients. Approximately 25 percent of patients with epilepsy took antiepileptic and/or neuroleptics to prevent the occurrence of seizures. Conclusion: A significant correlation was observed between ID associated to genetic causes and the increase of consanguinity rate.

RESUMEN

Consanguinity is a social behavior characterized by the arrangement of marriages between relatives. It coincides generally with the geographic distribution of recessive genetic diseases as it increases the likelihood of homozygosis and, consequently, the incidence of their pathologies in the population. In this pilot study, we assess the effect of inbreeding on the burden of hemoglobinopathies in Northern Morocco. From January 2016 to December 2018, 197 children born in the studied region to three ancestral generations and diagnosed with hemoglobinopathies were subject to investigation. The rate of consanguinity in the parents' generation of children with hemoglobinopathies was 50.25%, with first cousin marriages accounting for 68.69% of consanguineous unions (FI = 0.02). The corresponding rates in the general population, based on a sample of N = 900, were 29.67% and 82.02%, respectively. The marriages between first cousins are the most common among the other types of consanguineous unions. Our study propounds that consanguinity substantially contributes to the hemoglobinopathy burden in the studied region and has changed little over time. Refraining from consanguineous marriages and detecting couples at risk could contribute to the reduction of the incidence of genetic diseases in our country.

RESUMEN

AIM: The aim of this work was to study overweight and obesity and their associated complications according to obesity indicators in a population of Tangier. METHODS: A total of 480 overweight and obese patients were included in this study, referred to hospital Duc Tovar of Tangier during a period of 12 months. The collection of data has been done through a questionnaire which included anthropometric, clinical and biochemical characteristics of each patient. Statistical analyses included chi2 test, student's t-test, ANOVA, and multiple linear regression analyses. RESULTS: The mean age of our patients was 45.56 ±â€¯12.23 years, the mean body mass index (BMI) was 33.97 ±â€¯5.84 Kg/m2 and the average waist circumference (WC) was 109.78 ±â€¯15.42 cm. Overweight affected 25.2% and obesity 74.8%, whose 88.8% of subjects had abdominal obesity. All the metabolic abnormalities were significantly associated with abdominal obesity (measured by WC). However, only total cholesterol (p₌0.001) and triglycerides (p₌0.000) were significantly associated with different classes of obesity (measured by BMI). The most common complications of obesity and overweight were: type 2 diabetes (56.8%), arterial hypertension (52%), dyslipidaemia (43.9%), and cardiovascular disease (CVD) (24.3%). Hypertension and hyperglycaemia were the major risk factors for developing CVD with OR = 3.81 (95% CI:1.363-10.698; p < 0.05) and OR = 2.610 (95% CI:1.648-4.133; p < 0.001) respectively. CONCLUSION: Obesity exposes to several chronic complications, the most important in our study were type 2 diabetes and hypertension; these complications increased significantly with abdominal obesity that has constituted important risk factors of CVD.

RESUMEN

Unlike the other hemoglobinopathies, few researches have been published concerning α-thalassemia in Morocco. The epidemiological features and the mutation spectrum of this disease are still unknown. This regional newborn screening is the first to study α-thalassemia in the north of Morocco. During the period from January 2015 to December 2016, 1658 newborns umbilical blood samples were investigated. Suspected newborns were screened for α-globin defects using Gap-PCR and Multiplex Ligation-dependent Probe Amplification technique. The prevalence of α-thalassemia, its mutation spectrum, and its allelic frequencies were described for the first time in Morocco. Six different α-globin genetic disorders were detected in 16 neonates. This screening valued the prevalence of α-thalassemia in the studied population at 0.96% and showed the wide mutation spectrum and the heterogeneous geographical distribution of the disease. A high rate of carriers was observed in Laouamra, a rural commune in Larache province. Heterogeneity of α-globin alleles in Morocco explains the high variability of α-thalassemia severity. This diversity reflects the anthropological history of the country. These results would contribute to the prevention of thalassemia in Morocco directing the design of a nationwide screening strategy and awareness campaign.

RESUMEN

Systemic Lupus Erythematosus (SLE) is a complex autoimmune disease with a high female predominance. To date, studies about SLE in Morocco are few. This retrospective study describes the clinical and immunological features in a series of 50 SLE Moroccan patients in University Hospital Center of Rabat, Morocco, between December 2011 and December 2013. All patients were screened for antinuclear antibodies (ANA) and anti-DNA antibodies by indirect immunofluorescence, followed by identification of anti-extractable nuclear antigen antibodies by ELISA. The female to male ratio was 6.1:1. Mean age was 31.72 years. The main clinical manifestations were arthritis (82%), mucocutaneous manifestations (80%), renal manifestations (50%), and hematological features (46%). Of the mucocutaneous features, the highest frequencies were observed in the malar rash (68%) and photosensitivity (60%). Of the hematological features, lymphopenia was most frequently observed in 30% of patients, followed by hemolytic anemia in 16% and leucopenia and thrombocytopenia in 8%. Central nervous system was involved in 10%. ANA were found in 88%, anti-DNA antibodies in 56%, and anti-Sm antibodies in 50%. Anti-SSA, anti-SSB, anti-Sm/RNP, and anti-Scl70 antibodies were detected in 38%, 10%, 48%, and 8%, respectively. Our data show that, in our patients, the main clinical and immunological features of SLE remain comparable to patients from other Arab countries.

RESUMEN

Scleroderma or systemic sclerosis (SSc) is frequently detected at an advanced stage due to diagnosis difficulties. Salivary biomarkers, if existing, could be used for predictive diagnosis of this disease. Human saliva contains a large number of proteins that can be used for diagnosis and are of great potential in clinical research. The use of proteomic analysis to characterize whole saliva (WS) in SSc has gained an increasing attention in the last years and the identification of salivary proteins specific for SSc could lead to early diagnosis or new therapeutic targets. This review will present an overview about the use of WS in SSc studies. The proteomic technologies currently used for global identification of salivary proteins in SSc, as well as the advantages and limitations for the use of WS as a diagnostic tool, will be presented.

RESUMEN

The occurrence of secondary breast cancers in women previously exposed to chest irradiation for Hodgkin lymphoma (HL) is considered as a major issue for the quality of life of these long-term survivors as well as a challenge for clinical management. This study reports a case of a woman treated for HL at the age of 24 years, who developed breast cancer after an interval of 20 years. This case highlights once again the importance of awareness among HL survivors about their increased breast cancer risk and re-launches the debate about the efficacy of adoption of breast screening guidelines.

RESUMEN

BACKGROUND: Literature data reported a higher frequency of breast cancer in young women (BCYW) in developing countries. BCYW is associated with delayed diagnosis, aggressive biology and poor prognosis. However, our knowledge of biological profile, treatment received and outcome of young patients is still limited in Morocco. We propose to analyze clinicopathologic, therapeutic and prognostic features of BCYW among a series of patients native and/or inhabitant of North of Morocco. METHODS: We carried out a retro-prospective study of 331 infiltrating breast cancer cases registered between January 2010 and December 2015. Details of tumor pathology, treatment and outcome were collected. Disease-Free Survival (DFS) and Overall Survival (OS) were assessed by Kaplan-Meier analysis. RESULTS: A total of 82 patients were diagnosed with breast cancer at the age of 40 or younger (24.8%). Median age was 36 years. More than one quarter (26%) of patients had family history of breast or ovarian cancer. Advanced stages accounted for 34.2% of cases. Median tumor diameter was 2.8 cm. Intermediate and high-grade tumors represented 47.6% and 40.2%, respectively. Nodal involvement was present in 58.5% and lymphovascular invasion was found in 47.7% of the patients. About two thirds (66.2%) of tumors were hormone receptor positive, 29.2% over-expressed HER2 receptor and 23% were triple negative. Patients underwent breast conserving surgery in 38.2% of cases, 61.7% were offered adjuvant chemotherapy and 84.6% received hormone therapy. Five-year DFS and OS were respectively 88.9% and 75.6%. Locoregional recurrence occurred in 2.8% of cases and 8.3% of patients developed distant metastases. CONCLUSION: Our findings are in accordance with previous studies that have shown a higher frequency of breast cancer among Moroccan young women. In line with literature data, clinicopathologic profile seems to be aggressive and prognosis is pejorative in our series.

RESUMEN

Prelabour rupture of membranes (PROM) at term occurs in 5 to 10% of pregnancies. It accounts for a significant proportion of neonatal morbidity and mortality. The aim of this case study was to determine the maternal and obstetric prognostic factors as well as full-term newborns outcomes in pregnancies complicated by prelabour rupture of membranes in patients hospitalized or managed at the outpatient clinic. We conducted a retrospective study of all cases of full-term infants born to mothers whose pregnancy was complicated by PROM, recorded in the neonatology department at the Children's Hospital of Rabat between 1 January and 31 July 2014. During the study period we collected 144 cases of PROM isolated from a total of 2,400 live births (LB), ie a prevalence of live births (6%), distributed as follows: 6 cases of PROM (4%) between 6 and 12 hours, 14 cases (9.7%) between 12 and 18 hours, 28 cases (19.4%) between 18 and 24 hours and 96 cases (66.6%) of more than 24 hours. The majority of parturients were within the age-group 25-35 years with a rate of 52%. The diagnosis of associated chorioamniotitis was retained in 8.3% of cases. Parturients were treated with oral or parenteral antibiotic prophylaxis in 28% of cases with clear amniotic fluid in 81% of cases. The diagnosis of probable MFI was retained in 46 cases, 65.2% in the subgroup > 18 h versus 26% and 8.7% in subgroups 12-18 h and <12 h respectively. On admission, there was a male predominance of 58.3%, newborns were asymptomatic in 76% of cases, they suffered from respiratory distress in 42.8% of cases, jaundice in 31.45% of cases, fever in 14.2% of cases and signs of neurological distress in 11.5% of cases. All hospitalized newborns (72% of cases), were treated with antibiotics for a period ranging from 5 to 10 days with an average hospital stay of 2.44 days. This case study highlights the significant risk of MFI associated with PROM even in pregnant woman at term. This risk is major when rupture of membranes occurs after 24 hours of time. In the majority of cases the amniotic fluid is clear and newborns are asymptomatic on admission, leaving antibiotic therapy in these newborns a controversial subject.
