Protective Effect of Morocco Carob Honey Against Lead-Induced Anemia and Hepato-Renal Toxicity.

BACKGROUND/AIMS: Natural honey has many biological activities including protective effect against toxic materials. The aim of this study was to evaluate the protective effect of carob honey against lead-induced hepato-renal toxicity and lead-induced anemia in rabbits. METHODS: Twenty four male rabbits were allocated into four groups six rabbits each; group 1: control group, received distilled water (0.1 ml / kg.b.wt /daily); group 2: received oral lead acetate (2 g/kg.b.wt/daily); group 3: treated with oral honey (1g /kg.b.wt/daily) and oral lead (2 g/kg.b.wt/daily), and group 4: received oral honey (1 g/kg.b.wt/daily). Honey and lead were given daily during 24 days of experimentation. Laboratory tests and histopathological evaluations of kidneys were done. RESULTS: Oral administration of lead induced hepatic and kidney injury and caused anemia during three weeks of the exposure. Treatment with honey prevented hepato-renal lead toxicity and ameliorated lead-induced anemia when honey was given to animals during lead exposure. CONCLUSION: It might be concluded that honey has a protective effect against lead-induced blood, hepatic and renal toxic effects.

Omphalolith: a rare entity but important to recognize.

Omphalolith (umbolith) is an uncommon entity under normal circumstances. However, in a deeply retracted umbilicus in an obese individual, the accumulation of sebum and keratin may lead to the formation of a stone. This calculus may remain undiagnosed for many years until revealed by secondary infection or ulceration. We report an interesting case of an omphalolith in a young woman. In our literature search, very few cases of omphalolith have been reported.

Pedunculated lipoma causing colo-colonic intussusception: a rare case report.

BACKGROUND: Intussusception is a relatively common cause of intestinal obstruction in children but a rare clinical entity in adults, representing fewer than 1% of intestinal obstructions in this patient population. Colonic lipomas are uncommon nonepithelial neoplasms that are typically sessile, asymptomatic and incidentally found during endoscopy, surgery, or autopsy. CASE PRESENTATION: A 55-year old man visited our emergency department with severe abdominal pain, multiple episodes of vomiting, abdominal distension. Abdominal ultrasound sonography and computed tomography showed a sausage-shaped mass presenting as a target sign, suggestive of intussusception. Surgery revealed a hard elongated mass in the right colon wihch telescoped in the transverse colon and caused colo-colonic intussusception. Rhigt hémicolectomy was performed and pathology documented a mature submucosal lipoma of the colon. We describe the difficulties in diagnosis and management of this rare cause of bowel obstruction and review the literature on adult intussusceptions. CONCLUSION: A large submucosal lipoma is a very rare cause of colon intussusception that presents as intestinal obstruction in patients without malignancy. CT and magnetic resonance imaging remain the methods of choice for studying abdominal lipomas, particularly those rising into the layers of the colonic wall. Surgical resection remains the treatment of choice and produces an excellent prognosis.

Aspergilloma in combination with adenocarcinoma of the lung.

A 60 year old male with a long standing history of smoking was referred to our department for surgery of aspergilloma in right upper lung lobe diagnosed by computed tomography and confirmed by computed tomography guided needle aspiration biopsy. A lobectomy was performed. Histological study of the surgical specimen revealed a pulmonary adenocarcinoma associated with aspergilloma. By presenting this case we suggest that every case of pulmonary aspergilloma should be examined for malignancies, especially in smokers.

Twelve cases of metaplastic carcinoma of the breast: experience of the university hospital of Fez Morocco.

INTRODUCTION: Metaplastic breast carcinoma (MBC) is a distinct invasive breast carcinoma. It is a rare and heterogeneous group of malignancies, generally characterized by hormone receptor and human epidermal growth factor receptor 2 (HER2) negativity. The aim of the study is to evaluate epidemiological aspects, clinical characteristics, pathological features and biological profile of MBC cases diagnosed in our institution. METHODS: All patients with MBC diagnosed and treated in our institution between January 2004 and June 2009 were included. RESULTS: Twelve patients were identified. The median age was 46.5 (range 35-57 years) and the average tumor size was 6.9 cm (3.5-18 cm). Seven cases were purely squamous cell carcinomas, one was an adenosquamous carcinoma and four cases were mixed epithelial and mesenchymal metaplastic carcinomas. Primary treatment was mastectomy in 11 patients and wide local excision in one patient. There was lymph node (LN) involvement in four patients. Three patients were stage IIA, eight were stage III (2 IIIA, 6 IIIB), and one was stage IV. Estrogen and progesterone receptors status and over expression of HER2 were assessed. Eleven tumors had a basal-like phenotype and one tumor had luminal B phenotype. CONCLUSION: This study found a high incidence of MBC compared to Western countries. The tumors occur at an earlier age of onset and are usually diagnosed at a late stage with predominance of squamous cell carcinoma subtype. LN metastases are found in the third case and the tumors are most often basal-like phenotype significantly reducing therapeutic options.

Multifocal tuberculosis revealed by multiple cutaneous gummas in the immunocompetent.

Cutaneous tuberculosis is rare. Its occurrence in multifocal tuberculosis (MT) is uncommon and happens frequently in the context of immunosuppression. We report the case of MT with multiple cutaneous gummas and bone and lung involvement that occurred in an apparently immunocompetent patient.

[Malignant mesothelioma of the ovary: a case report]. / Mésothéliome malin de l´ovaire: à propos d´un cas.

Primary malignant mesothelioma of the ovary (PMMO) is an extremely rare tumor which can develop from mesothelial cells. This neoplasia is caused predominantly by exposure to asbestos or other cancer-causing agents. Preoperative assessment, based on computed tomography (CT) scan, magnetic resonance imaging and positron emission tomography, is essential for cancer staging. Anatomopathological diagnosis is based on immunohistochemical findings. PMMO is an exceptional disease involving a multidisciplinary therapeutic strategy including the use of chemotherapy which improves the management and prognosis of patients. This study reports the case of a female patient undergoing suboptimal surgery complemented by adjuvant chemotherapy with complete radiological response and 1-year disease-free survival.

Pelvic and Lumbar Pain Revealing Bone Sarcoidosis: A Case Report.

A 54-years-old woman suffered from a bilateral pelvic and lumbar pain. She had a systemic investigation shows a diffuse bone lesions. A biopsy of iliac bone was done and revealed sarcoidosis. Bony manifestations of sarcoidosis are rare and challenging to diagnose. Our report shows that MRI with diffusion weighted sequences is a simple and non invasive technique to evaluate bone infiltration. It helps to distinguish inflammatory disease from metastatic lesions and to guide the osseous biopsy. Moreover, fluorodeoxyglucose PET scan, are useful in establishing the extent of damage and measuring disease activity.

A rare case of locally advanced fibrosarcoma of diaphysal humerus managed successfully with limb-sparing procedures after neoadjuvant chemotherapy.

Fibrosarcomas (FS) of bone are a rare malignancy accounting for less than 5% of all primary malignant bone neoplasms. Diagnosis and treatment approaches of this entity are complex and require a skilled and experienced multidisciplinary team.Authors report their experience with a case of FS of humerus showing a pathologic complete response to neo-adjuvant chemotherapy based on adriamycin, cisplatin and ifosfamid. This approach allowed limb-sparing surgery with an excellent functional and psychological result.

Intradural extramedullary ependymoma: is there constantly a hormonal relationship?

BACKGROUND: Ependymoma is a glial tumor that occurs in the central nervous system. The intradural extramedullary location of this neoplasm is very rare. The authors report a case of spinal intradural extramedullary ependymoma in a male and discuss its pathogenesis as well as its clinical, radiological, and therapeutical features. CASE DESCRIPTION: A 31-year-old man was admitted at the author's institution. The patient has had 1-year history of cervical pain, progressive quadriplegia, and bladder disturbances. Magnetic resonance imaging revealed an enhanced cervical intradural extramedullary tumor extending from the bulbomedullary junction to the C3 level, with severe spinal cord compression. Emergency surgical resection was performed, and a total removal of the lesion was accomplished. One year and half later, a local recurrence associated to a small cerebellar lesion was noticed justifying a second spinal intervention. Both surgical interventions demonstrated an intradural extramedullary ependymoma without attachment to the spinal cord or to the dura mater. Adjuvant craniospinal radiotherapy was recommended to the patient. CONCLUSION: The insufficiency of hormonal theory to explain solely the pathogenesis of this tumor might reveal other potential factors that have not been discussed in earlier literature.

[Parotid metastasis from carcinoma of the breast: report of a case and review of the literature]. / Métastase parotidienne d'un cancer du sein: à propos d'un cas et revue de la littérature.

Parotid metastasis from carcinoma of the breast is very rare, only a few cases have been reported in the literature. We here report the case of a 43-year old patient treated for right breast cancer in whom left parotid metastasis (confirmed histologically) occurred two years after the end of the treatment.

EGFR Amplification and IDH Mutations in Glioblastoma Patients of the Northeast of Morocco.

Glioblastomas are the most frequent and aggressive primary brain tumors which are expressing various evolutions, aggressiveness, and prognosis. Thus, the 2007 World Health Organization classification based solely on the histological criteria is no longer sufficient. It should be complemented by molecular analysis for a true histomolecular classification. The new 2016 WHO classification of tumors of the central nervous system uses molecular parameters in addition to histology to reclassify these tumors and reduce the interobserver variability. The aim of this study is to determine the prevalence of IDH mutations and EGFR amplifications in the population of the northeast region of Morocco and then to compare the results with other studies. Methods. IDH1 codon 132 and IDH2 codon 172 were directly sequenced and the amplification of exon 20 of EGFR gene was investigated by qPCR in 65 glioblastoma tumors diagnosed at the University Hospital of Fez between 2010 and 2014. Results. The R132H IDH1 mutation was observed in 8 of 65 tumor samples (12.31%). No mutation of IDH2 was detected. EGFR amplification was identified in 17 cases (26.15%). Conclusion. A systematic search of both histological and molecular markers should be requisite for a good diagnosis and a better management of glioblastomas.

[Lynch syndrome: case report and review of the literature]. / Syndrome de Lynch: à propos d'un cas et revue de la litterature.

Lynch syndrome or hereditary nonpolyposis colorectal cancer (HNPCC) is the most common form of hereditary colorectal cancers. It increases cancer susceptibility, the risk of colorectal cancer in first-degree, endometrial cancer in women, and to a lesser extent, other cancers (ovarian, small bowel, stomach, urinary tract and hepatobiliary). Thus, the cumulative risk of developing colorectal cancer or endometrial cancer at the age of 80 years rises to 20 and 40% respectively. These cancers are characterized by a positive family history, their occurrence at an early age, and by the development of metachronous cancers in the same individual. This syndrome is transmitted in an autosomal dominant manner. The genes whose alteration is associated with the presence of an HNPCC belong to the family of DNA mismatch repair genes (DNA mismatch repair or MMR): MSH2, MLH1, and MSH6 are involved, in decreasing order of frequency, in 35%, 25% and 2% of cases respectively. Colonoscopic and gynecological monitoring is recommended for patients with a constitutional mutation in MSH2, MLH1 or Msh6 genes. We report one of the first moroccan case with Lynch syndrome whose constitutional mutation in the MLH1 gene was identified in a family member with colon cancer. In reply to the inquiry ofother healthy family members, a presymptomatic diagnosis was made allowing to formulate an appropriate monitoring strategy. Our study aims to highlight the role of oncogenetics in the management of patients with cancer and their families.

Prevalence of IDH1/2 Mutations in Different Subtypes of Glioma in the North-East Population of Morocco.

BACKGROUND: Genetic alterations in gliomas have increasing importance for classification purposes. Thus, we are especially interested in studying IDH mutations which may feature potential roles in diagnosis, prognosis and response to treatment. Our aim was to investigate IDH mutations in diffuse glioma patients diagnosed in university hospital centre of Fez in Morocco. MATERIALS AND METHODS: IDH1 codon 132 and IDH2 codon 172 were direct-sequenced in 117 diffuse glioma samples diagnosed and treated in University Hospital Hassan II between 2010 and 2014. RESULTS: The R132H IDH1 mutation was identified in 43/117 tumor samples and R172K IDH2 mutation was detected in only one anaplastic oligodendroglioma. IDH mutations were observed in 63.2% of astrocytomas, 73.3% of diffuse oligodendrogliomas and 12.90% of glioblastomas. CONCLUSIONS: Our results confirmed other studies published earlier for other populations with some small discrepancies.

Primary hepatoid carcinoma of the ovary: a case report.

Primary hepatoid carcinoma of the ovary (HCO) is a very rare type of high-grade invasive malignant ovarian tumor with hepatic differentiation and production of α-fetoprotein (AFP). We describe a 78-year-old Moroccan woman who presented to our hospital with abdominal distension and purplish nodules infiltrating the para umbilical skin with weight loss and impairment of her performance status. Excisional biopsy of the para umbilical nodule revealed a cutaneous localization of moderately differentiated adenocarcinoma and pelvic ultrasonography noted the presence of a tumoral right adnexal mass. The patient underwent an exploratory laparoscopy which found peritoneal carcinomatosis with pelvic adhesions allowing only a peritoneal biopsy. Diagnosis of primary hepatoid carcinoma of the ovary was established on the basis of classic histopathologic findings, immunohistochemical staining and marked elevation in serum of α-fetoprotein more than the carbohydrate antigen 125. The patient received 3 cycles of chemotherapy based on Carboplatin and Paclitaxel with disease progression. No second line chemotherapy was given because of the drop of patient's performance status to 3. The patient died one month later.
