Background and Aims:In sickle cell disease (SCD) patients admitted for intensive care, evaluation of platelet counts in different types of sickle cell complications and its prognostic relevance are not well-studied. Illuminating these aspects were the objectives of this study.Materials and Methods:A chart review of 136 adult SCD patients consecutively admitted to our Intensive Care Unit (ICU) was done. The prognosis on day 1 was assessed by Acute Physiology and Chronic Health Evaluation (APACHE II) and multiple organ dysfunction scores (MODS). Receiver operating characteristic (ROC) curves evaluated the ability of platelet counts, MODS, and APACHE II scores to predict survival.Results:The most common types of crises were severe pain (n = 53), acute chest syndrome (n = 40), and infection (n = 18); 17 patients were nonsurvivors. Platelet counts varied widely (range, 19–838 × 109/L) with thrombocytopenia (n = 30) and thrombocytosis (n = 11). Counts correlated directly with leukocytes and reticulocytes; inversely with lactate dehydrogenase, APACHE, and MODS scores. Areas under ROC curve for platelets, MODS, and APACHE scores to predict survival were 0.73, 0.85, and 0.93, respectively.Conclusions:In severe sickle cell crisis thrombocytopenia is more common than thrombocytosis. In the ICU, day 1 platelet counts correlate inversely with prognostic scores and are significantly reduced in multi-organ failure and nonsurvivors. A platelet count above 175 × 109/L predicts patient survival with high specificity and positive predictive value but lacks sensitivity.

Hydroxyurea (HU) is used as a disease-modifying agent in sickle cell disease (SCD). Its beneficial effects have been ascribed to inhibition of the sickling process through increase of fetal hemoglobin (HbF) levels and influence on multiple factors affecting adhesion of erythrocytes to vascular endothelium. The present study investigates the effect of HU in SCD patients who were grouped on the basis of association with α- and β-thalassemia using routine laboratory methods. A retrospective cross-sectional chart-review was done of 51 adult Bahraini SCD patients attending Salmaniya Medical Complex, Bahrain. Four sub-groups of cases were identified: (i) homozygous sickle cell anemia, 24 cases; (ii) SCD with microcytosis, 16 cases; (iii) sickle α-thalassemia, seven cases; and (iv) sickle β thalassemia, four cases. Documented laboratory and clinical data included hemoglobin level (Hb), hematocrit (Hct), red cell indices, hemoglobin fractions, hospital admissions (frequency), number of inpatient-days, pain episodes (frequency) and red cell transfusion requirement (number of units). Pre- and post-treatment data were compared. Hydroxyurea treatment led to highly significant reduction of HbS % and pain crisis episodes in all patient groups. Other changes such as increases of total hemoglobin, Hct and HbF and reduction of hospital admissions, inpatient days and red cell units transfused also occurred but with less consistent levels of significance within patient sub-groups. Treatment with HU is beneficial for all subgroups of Bahraini SCD patients, without or with α- and β-thalassemia interactions.

Result: Thirty-three (77.3%) were type I, 7 (13.6%) were type II and 4 (9.1%) were type III. GT was mainly found in females and in pediatric age group. There was a good correlation between flow cytometry study and aggregation study. Conclusion: GT is a common bleeding disorder in a community where consanguineous marriage is common.

Background: This study investigates and analyses the thyroid nodules in Bahrain, and correlates the diagnosis of cytopathology with a subsequent excision histopathology. Materials & Methods: We conducted a retrospective study for all thyroid cases diagnosed at the Salmaniya Medical Complex during a 7-year period (January 2013 to December 2019). Results: A total of 1218 thyroid nodules were diagnosed during the study period. Among them, 1,037 (85%) of the patients were females and 181 were males (15%), with an average age of 48.2 years. Surgical excision was performed on 263 out of 1,037 (25%) of the cases. Conclusions: The study revealed that the prevalence of thyroid nodules is higher among females. The most common nodules are benign multinodular goiters. A statistically significant correlation was observed between fine needle aspiration cytology (FNA) and surgical excision of the thyroid nodule.
