Abstract
Griscelli syndrome (GS) is a rare genetic disorder that encompasses three different subtypes (GS type 1 (GS1), GS type 2 (GS2), and GS type 3 (GS3)), in which isolated neurological manifestations without immune system implications are typically seen in GS1, while neurological involvements in GS2 should be attributed to the macrophage and lymphocyte invasion of the central nervous system (CNS), under associated hemophagocytic lymphohistiocytosis (HLH). The presence of the clinical, biological, and hematologic features of HLH help explain the neurological defects that GS2 patients unusually present. In our case report, however, we attempt to highlight an uncommon presentation of GS2 involving a hemiparesis, along which we did not have any clinical or biological features of HLH. We also collect and evaluate similar published cases that feature this problem of explaining the neurological manifestations among GS2 patients.

Abstract
Objective Coronavirus disease 2019 (COVID-19) is a viral disease caused by severe acute
respiratory syndrome coronavirus 2. The clinical manifestations and the
evolution of patients with COVID-19 are variable. In addition to respiratory
involvement, COVID-19 leads to systemic involvement and can affect the
hematopoietic system. This study aimed to evaluate the prognostic value of
hematological and hemocytometric parameters in predicting the severity of
patients with COVID-19. Methods We performed a retrospective study at Mohammed VI university Hospital from 1
March to 11 November 2020. We collected demographic characteristics and
hematological findings of incident COVID-19 cases. Results A total of 245 patients were included in our study. We found that the rate of
lymphopenia was significantly reduced in patients who were severely affected
by COVID-19. Additionally, the rate of neutrophilia, the neutrophil side
fluorescence light signal, monocyte fluorescent intensity, monocyte size,
the neutrophil-to-lymphocyte ratio, the platelet-to-lymphocyte ratio, and
the lymphocyte-to-monocyte ratio were significantly elevated in patients who
were severely affected by COVID-19. Conclusions These results are consistent with the literature regarding the predictive
value of these markers. A prospective validation in a large population with
a longer follow-up is required.

Immunophenotypic challenges in diagnosis of CD79a negativity in a patient with B acute lymphoblastic leukemia harboring intrachromosomal amplification of chromosome 21: a case report. J Med Case Rep 2021; 15:531. [PMID: 34706776 PMCID: PMC8555128 DOI: 10.1186/s13256-021-03128-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Accepted: 09/22/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Being expressed in all stages of B-cell development and having a significant value on the European Group for the Immunological Characterization of Acute Leukemias scoring system, CD79a is considered as an excellent pan-marker for lineage assignment of B cells by flow cytometry. Therefore, any lack or decrease in CD79a expression makes the diagnosis of B acute lymphoblastic leukemia cases very challenging, especially in developing country laboratories where flow cytometry analyses are not always available and, when they are, they are limited in the number of markers used for lineage assignment. Since this case is potentially interesting, we report a B acute lymphoblastic leukemia case with a lack of expression CD79a associated with intrachromosomal amplification of chromosome 21 genetic abnormality. We further discuss the practical challenges in the diagnosis of this case. CASE PRESENTATION We present the case of an 8-year-old Caucasian boy from eastern Morocco who was initially hospitalized for a hemorrhagic syndrome. Peripheral blood smear examination showed a significant number of blasts suggesting acute leukemia. Bone marrow was studied for morphology, cytochemistry, immunophenotyping, and cytogenetics. Flow cytometry analyses showed expression of CD19, CD22, CD10, CD34, and HLA-DR markers by leukemic blasts. The expression of CD79a, which was checked with two different monoclonal antibodies, confirms that this marker was severely decreased in this case. Cytogenetic study performed by fluorescence in situ hybridization revealed the presence of intrachromosomal amplification of chromosome 21, a cytogenetic abnormality that is specific for B acute lymphoblastic leukemia. CONCLUSION CD79a is one of the critical markers in the assignment of B acute lymphoblastic leukemia. In our case, we were lucky enough to be assisted by a few other markers of the B lineage that were positive in this case. Also, we mention the importance of proceeding to cytogenetic study, which in our case helped us to confirm the diagnosis made by flow cytometry by highlighting a cytogenetic abnormality that is specific to B acute lymphoblastic leukemia.

Abstract
Background The combination of visceral leishmaniasis (VL) and macrophage activation syndrome (MAS) makes the diagnosis difficult due to their similar clinical presentation, with a poor prognosis especially since the treatment is still poorly codified. We report the case of a 17-month-old female patient from Berkane, presenting for a 3 months history of anarchic fever with anemic syndrome made up of pallor and hemorrhagic syndrome made up of epistaxis. Physical examination revealed a temperature of 39 ° C, lower limbsedema, paleness of skin and mucous membranes, gingival petechiae, bleached hair, and hepatosplenomegaly. Case presentation The complete blood count showed pancytopenia with deep aregenerative normochromic normocytic anemia at 3 g/dL, leukocytes were at 4860/mm 3 with neutropenia at 680/mm 3 and thrombocytopenia at 12.000/mm3, the blood smear was without abnormality. These anomalies were associated with a hypoalbunemia, hypertriglyceridemia, hyperferritinemia, lactate dehydrogenase (LDH) level was at 337 IU/L, low prothrombin time (PT) at 56 % and fibrinogen level at 1 g/L. The direct Coombs test was positive. Examination of the myelogram revealed the presence of leishmania bodies and figures of hemophagocytosis. A diagnosis of visceral leishmaniasis associated with MAS was made. The patient was put on liposomal amphotericin B and corticosteroid therapy with good clinical and biological evolution and good therapeutic tolerance. Conclusion The association of VL and MAS remains rare and should be evoked even in non-endemic areas since late diagnosis worsens the prognosis and may even be responsible for the death of patients despite an aggressive treatment.

Abstract
Background and Purpose The presence of yeasts in the urine is not synonymous with urinary tract infection since it can result in simple colonization or contamination. Regarding this, it is required to further clarify the epidemiological profile of funguria. Accordingly, the present study was conducted to establish the epidemiology of funguria in the Mohammed VI Teaching Hospital of Oujda, Morocco. Materials and Methods This retrospective study was conducted on all urine samples sent for cytobacteriological examination to a microbiology laboratory over a period of 28 months (i.e., from March 2016 to June 2018). After the removal of duplicates, the urine samples were treated according to the recommendations of the medical microbiology standards. Results A total of 15,165 urine samples were collected. Urinary colonization accounted for 4.94% (n=749) of cases. The infections of the urinary tract accounted for 5.35% (n=811) of cases. Microbial isolates (n=1,669) in colonization and urinary tract infections were dominated by bacteria (93.47%, n=1,560). Furthermore, the yeasts accounted for 6.53% (n=109) of the isolates. Candida albicans was isolated from 56.88% (n=62) of funguria cases. The risk factors for funguria in our series were essentially old age, admission to intensive care unit, and broad-spectrum antibiotic therapy. Conclusion The current level of knowledge about the clinical situations leading to funguria with the improvement and popularization of efficient identification techniques for yeasts other than C. albicans should redress the epidemiology of funguria. This should allow the knowledgeable societies to establish the rules of interpreting the cytobacteriological examination of the urine in case of funguria, as for bacteriuria.

Abstract
Background The aim of this work is to present the results of a comparative study between the ALT assay on Integra 400 plus Roche Diagnostic versus Architect ci8200 of Abbott Diagnostic. Methods A total of 200 patients hospitalized in the various departments of the university hospital Mohammed VI of Oujda were prospectively tested on two systems: Abbott Architect ci8200 and Roche Integra 400 plus. Both analyzers use the spectrophotometric technique by coupling the transamination reaction to the oxidation-reduction reaction at NAD. The agreement of the results between the different techniques was evaluated using the Bland-Altman difference diagram and the Passing-Bablok and Deming regression line. Results There was a high concordance between the two assays: the equation of the Passing-Bablok line is YArchitect = −0,5625 + 0,9917 XIntegra with a correlation coefficient r2 = 0.999. The Bland-Altman diagram shows that the mean bias between the two methods is of the order of 1.1 IU/L and the difference between the ALT measurements by Architect and Integra is in the range of −1.4 to 3.6. Conclusion Our study shows a high correlation of the ALT assay results between the architect ci8200 and Integra 400 plus.

Abstract
Gaucher disease (GD) is a lysosomal storage disease. It corresponds to a congenital deficit in β-glucocerebrosidase. This pathology should be considered in the presence of unexplained splenomegaly, with or without signs of haemorrhage, skeletal manifestations or hepatomegaly. The diagnosis is based on the measurement of the β-glucocerebrosidase activity but the preanalytical process should be respected in order to avoid the under-diagnosis of this disorder and the delay of its management. We report two cases of Gaucher disease collected at Mohammed VI University Hospital and Al Farabi regional hospital in Oujda. We have emphasized the need for a reference center for overload diseases.

Abstract
Non-secretory myeloma (NSM) is a rare form of myeloma. It is defined as monoclonal plasmocytic proliferation of the bone marrow with the same clinical and radiological manifestations of myeloma. However, plasma cells are unable to secrete immunoglobulin (serum and urinary electrophoresis are negative and free light chain measurement is unquantifiable). This variant of multiple myeloma (MM) usually poses a diagnostic challenge to the biologist and clinician. We report a rare case of non-secretory myeloma in a 76-year-old patient who was diagnosed at the Mohammed V University Hospital Center in Oujda, Morocco.

Abstract
Tuberculosis disease, in its extra pulmonary form, remains a difficult diagnosis because of its atypical symptoms and evolution. We have observed a case of acute tuberculosis neuromeningitis, without being able to make a definite diagnosis prior to the patient's death because of the negativity of the initial bacteriological samples. We started the most probable appropriate treatment but in vain. This case allows us to challenge diagnostic methods and resulting treatments in emergency cases where tuberculosis is suspected. Moreover, it seems essential to do everything possible to find the bacterium when confronted with a patient with risk factors and clinical and radiological symptoms compatible with tubercular disease, before the disease becomes acute.

Abstract
Hemolytic and uremic syndrome (HUS) is a classical form of thrombotic microangiopathies characterized by the association of hemolytic anemia with schizocytes, thrombocytopenia, and acute renal failure. Two forms of HUS have been described: the typical form that occurs after ingestion of a strain of bacteria, usually Escherichia coli types, which expresses verotoxin (also called shiga-like toxin), typically followed by bloody diarrhea, and atypical HUS, which is rare during childhood and can also be revealed by bloody diarrhea. We report a case of a 25-month-old infant who presented with hematuria and pallor after an episode of diarrhea. Biological tests revealed anemia, thrombocytopenia, and renal failure. The diagnosis of typical HUS was made, but the causal microorganism was not identified. Progression was favorable within 5 days of plasma transfusions. Two months later, the patient presented with the same symptoms and neurological impairment without any diarrhea. Von Willebrand factor-cleaving protease activity (ADAMTS 13) was low. Therefore, the diagnosis of atypical HUS by severe deficiency of ADAMTS 13 was suggested. The treatment was based on plasma transfusions resulting in remission. Atypical HUS associated with severe ADAMTS 13 deficiency rarely occurs in childhood. The prognosis, usually threatening, has been completely transformed thanks to a better understanding of the pathogenesis and to therapeutic progress.

Abstract
Hereditary hemorrhagic telangiectasia (HHT) or Rendu-Osler-Weber disease is an autosomic dominant disorder, which is characterized by the development of multiple arteriovenous malformations in either the skin, mucous membranes, and/or visceral organs. Pulmonary arteriovenous malformations (PAVMs) may either rupture, and lead to life-threatening hemoptysis/hemothorax or be responsible for a right-to-left shunting leading to paradoxical embolism, causing stroke or cerebral abscess. PAVMs patients should systematically be screened as the spontaneous complication rate is high, by reaching almost 50%. Neurological complications rate is considerably higher in patients presenting with diffuse pulmonary involvement. PAVM diagnosis is mainly based upon transthoracic contrast echocardiography and CT scanner examination. The latter also allows the planification of treatments to adopt, which consists of percutaneous embolization, having replaced surgery in most of the cases. The anchor technique consists of percutaneous coil embolization of the afferent pulmonary arteries of the PAVM, by firstly placing a coil into a small afferent arterial branch closely upstream the PAVM. Enhanced contrast CT scanner is the key follow-up examination that depicts the PAVM enlargement, indicating the various mechanisms of PAVM reperfusion. When performed by experienced operators as the prime treatment, percutaneous embolization of PAVMs, is a safe, efficient and sustained therapy in the great majority of HHT patients.

Abstract
The objective of the present study was to evaluate the in vitro and in vivo anti-cancer effect of Nigella sativa L. seed extracts. The essential oil (IC50 = 0.6%, v/v) and ethyl acetate (IC50 = 0.75%) extracts were more cytotoxic against the P815 cell line than the butanol extract (IC50 = 2%). Similar results were obtained with the Vero cell line. Although all extracts had a comparable cytotoxic effect against the ICO1 cell line, with IC50 values ranging from 0.2 to 0.26% (v/v), tests on the BSR cell line revealed a high cytotoxic effect of the ethyl acetate extract (IC50 = 0.2%) compared to the essential oil (IC50 = 1.2%). These data show that the cytotoxicity of each extract depends on the tumor cell type. In vivo, using the DBA2/P815 (H2d) mouse model, our results clearly showed that the injection of the essential oil into the tumor site significantly inhibited solid tumor development. Indeed, on the 30th day of treatment, the tumor volume of the control animals was 2.5 +/- 0.6 cm(3), whereas the tumor volumes of the essential oil-treated animals were 0.22 +/- 0.1 and 0.16 +/- 0.1 cm(3) when the animals were injected with 30 microL (28.5 mg)/mouse and 50 microL (47.5 mg)/mouse per 48 h (six times), respectively. Interestingly, the administration of the essential oil into the tumor site inhibited the incidence of liver metastasis development and improved mouse survival.
