ABSTRACT

Introduction: Single nucleotide polymorphisms (SNPs) in DNA repair genes are mainly correlated with the response to radiotherapy in nasopharyngeal cancer (NPC). In NPC patients, previous research has studied the association between X-ray repair cross-complementing group 1 and 3 (XRCC1 and XRCC3) polymorphisms and radio-therapeutic response. The objective of our study was to test the association between XRCC1 Arg399Gln and XRCC3 Thr241Met polymorphisms and the response to radiotherapy in the NPC Moroccan population. Material and methods: A total of 100 patients with NPC were genotyped for polymorphisms in XRCC1 and XRCC3 genes. Results: The results revealed that the genotypes and alleles of both SNPs did not show any significant association with clinical stages (for XRCC1 Arg399Gln: p [genotype] = 0.559; p [allele] = 0.440) and (for XRCC3 Thr241Met: p [genotype] = 0.638; p [allele] = 0.567). Moreover, in the study of the association between the polymorphisms and radiotherapy, the response to radiation therapy between genotypes and alleles was not statistically significant (for XRCC1 Arg399Gln p [genotype] = 0.583; p [allele] = 0.459) and (for XRCC3 Thr241Met p [genotype] = 0.660; p [allele] = 0.590). Conclusions: The present study suggests that XRCC1 Arg399Gln polymorphism does not have any impact on the radio-therapeutic response in Moroccan NPC patients whereas XRCC3 Thr241Met polymorphism may act as a prognostic indicator for NPC patients treated with radiotherapy. However, studies with a larger sample are needed to confirm our results.

ABSTRACT

Schilder's disease is a rare form of multiple sclerosis. It concerns mostly teenagers and young adults. The Clinical signs and symptoms might be atypical for early multiple sclerosis which often mimics intracranial neoplasm or abscess. Their coursemay be either progressive or relapsing and remitting, with a high sensitivity to steroids. The knowledge of this rare form ofmultiple sclerosis may help radiologists in assessing a precise diagnosis. We report the case of a young 22-year-old patientadmitted to the emergency room with an array of headache, vomiting and frontal syndrome. Magnetic resonance imaging shows2 bilateral demyelinating frontal areas. The patient was put under corticosteroids bolus with discreet improvement in her clinicalcondition. After 6 months of follow-up, we did not notice any real clinical improvement. Although Schilder's disease isconsidered to be a variant of Multiple Sclerosis, its clinical and imaging features behaves more like a demyelinating conditionwith its monophasic course with, however, serious clinical consequences if the treatment is delayed.

ABSTRACT

Kienböck's disease is a condition characterized by avascular necrosis of the lunate. It is also known as lunatomalacia and aseptic or ischemic necrosis of the lunate. The aim of this work is to summarize and illustrate, through a case diagnosed in our institution, the radiological aspects of this rare entity, which occupy a prominent place in the diagnosis. A better understanding of this recently described nosological entity and a wide dissemination of its diagnostic criteria, especially by radiologists, should facilitate the diagnosis and treatment of patients.

ABSTRACT

Primary thyroid lymphoma is a rare clinical entity, which does not exceed 5% of the diagnosed lymphomas, occur more frequently in women than in men, with a peak incidence in the sixth decade of life. The relationship with chronic thyroiditis is well known. The Hodgkin subtype even rarer; little described in the literature; Posing a diagnostic problem. Diagnostic confirmation is usually carried out on the surgical specimen. To better understand this entity, we report the case of a 64-year-old patient, with no notion of chronic thyroiditis, admitted for Hodgkin's lymphoma of the thyroid, diagnosed on an anterior cervical mass. Thyroidectomy with histopathological and immunohistochemical studies confirmed the diagnosis. The patient had received chemotherapy type ABVD (Adriblastin-Bleomycin-Vinblastine-Dacarbazine) and programmed for radiotherapy.
