The patient underwent laparoscopic surgery for a lesion in the right fallopian tube. 3D-TVUS was crucial in precisely locating the gestational sac, aiding in effective treatment. Interstitial ectopic pregnancies risk severe hemorrhaging upon rupture. Rapid, accurate diagnosis is vital for lifesaving treatment and preventing critical complications.","PeriodicalId":320755,"journal":{"name":"Journal of Clinical and Experimental Hematology","volume":"64 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140741742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Khojah, Hadeel Alshareef, Lujain Alzahrani, M. Binhussein, A. Bukhari, Imad M Khojah","doi":"10.46439/hematol.2.007","DOIUrl":"https://doi.org/10.46439/hematol.2.007","url":null,"abstract":"WHIM (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis) syndrome is a rare primary immunodeficiency disorder characterized by susceptibility to human papillomavirus (HPV) infections, neutropenia, and hypogammaglobulinemia. WHIM syndrome is caused by a gain-of-function mutation CXCR4, leading to increased responsiveness of neutrophils and lymphocytes to CXCL12. This results in an accumulation of atypical hypersegmented mature neutrophils in the bone marrow and peripheral blood neutropenia. This case report discusses a 10-year-old girl who was diagnosed with WHIM syndrome at the age of four years following Haemophilus influenzae meningitis. She was found to have Tetralogy of Fallot at birth, which was surgically repaired when she was one year old. She was also found to have significant neutropenia during surgery and received multiple doses of G-CSF with a good response. She presented to the hospital at the age of four years with fever, neck stiffness, lethargy, and headache and was diagnosed with H. influenzae meningitis. Her immunology workup revealed significant neutropenia and hypogammaglobulinemia, as well as low antibody levels to H. influenza type B, tetanus toxoid, and Streptococcus pneumonia, despite up-to-date vaccination. Furthermore, decreased levels of T cells and B cells were detected. The patient was started on IgG replacement therapy and Bactrim prophylaxis. Bone marrow biopsy revealed granulocytic hyperplasia and occasional hypersegmented neutrophils, suggesting myelokathexis. Genetic testing revealed a heterozygous CXCR4 mutation with a premature stop codon (p.Ser338Ter), confirming the diagnosis of WHIM syndrome. This case report highlights the association of WHIM syndrome with congenital heart defects, such as Tetralogy of Fallot. A literature review revealed three other cases of congenital heart defects in patients with WHIM syndrome, indicating a potential role for CXCR4 and CXCL12 in septum formation. The rarity of the disorder and the lack of a universal screening tool makes the diagnosis of WHIM syndrome difficult. Therefore, physicians should consider WHIM syndrome in patients with congenital heart defects, particularly if they have recurrent HPV infections, neutropenia, and hypogammaglobulinemia.","PeriodicalId":320755,"journal":{"name":"Journal of Clinical and Experimental Hematology","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129346881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the past decade, a tremendous progress has been made in developing T cell engaging bispecific antibodies (BsAbs) targeting CD19 to treat B cell malignancies. The T cell engaging bispecific molecule binds to CD3 on a T cell and a tumor-associated antigen (TAA) on a target cell and redirects the T cell to a specific target cell bypassing the MHC restriction mechanism, leading to the formation of immune synapse between the T cell and target cell and target cell lysis [1,2].","PeriodicalId":320755,"journal":{"name":"Journal of Clinical and Experimental Hematology","volume":"17 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132462133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This will allow researchers to determine the healthy, average values for each rheological parameter, as well as left and right limits (2-standard deviations in either direction from average) respectively. It is understood that the mechanical characterization can be vastly improved by using Series of Physical Process framework that can further explore the viscous (liquid-like) and elastic (solid-like) properties along with the TEVP model parameterization.","PeriodicalId":320755,"journal":{"name":"Journal of Clinical and Experimental Hematology","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121239705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the early stages of life, it leads to severe negative consequences on the cognitive as well as growth and development children. Objective: This study is aimed to assess the prevalence of anemia and its associated factors among under five children attending at Bule Hora General Hospital, Guji Zone, Southern Ethiopia, from October to November, 2020. Method: A hospital based quantitative cross-sectional study was conducted at Bule Hora General Hospital, Southern Ethiopia. Convenient sampling technique was used to include 375 under-five children enrolled in the study. The pretested structure questionnaire was used to collect socioeconomic and demographic characteristics of study individuals after taking appropriate written informed consent. Then venous blood sample was collected from each child and analyzed for hemoglobin determination using Cell-DYN 1800 machine. Binary logistic regression models were used to identify associated factors of anemia. P-value ≤ 0.05 was considered as statistically significant. Result: The overall prevalence of anemia among under-five children was 13.2 % (50) at [95% CI=5.2-21.2%] of them anemic children, 11.1% (1) were had mild, 33.3% (3) moderate 55.6% (5) is severe anemia. In this study anemia was significantly associated with history of intestinal protozoa infection [AOR=2.13, 95% CI=1.35-9.270], malaria infection [AOR=5.42, 95% CI=0.307-11.034] and soil-transmitted helminths infection [AOR=6.09, 95% CI=2.047-27.54]. Conclusion: Anemia among under-five children in this study was found to be mild public health problem. It could be managed through preventing malaria infection, intestinal protozoa and soil-transmitted helminthic infection.
