Navigating the Challenges of Delayed Subdural Hemorrhage and COVID-19: A Case Report.

The delayed onset of posttraumatic subdural hemorrhage (SDH) represents non-specific clinical features, complicating the diagnostic process, especially in individuals predisposed due to pre-existing risk factors and comorbidities. This case report delineates the medical trajectory of a 61-year-old female patient who sustained a traumatic fall, initially displaying neither clinical nor radiological signs indicative of hemorrhage. However, three weeks post-injury, she developed altered mental status, cephalgia, and emesis. Diagnostic imaging unveiled a significant bilateral acute-on-chronic subdural hemorrhage exerting pronounced mass effect and leading to obliteration of the basal cisterns. Complicating her clinical picture was a concurrent SARS-CoV-2 infection and a medical history of hypertension. Emergent neurosurgical intervention was undertaken, encompassing the creation of bilateral burr holes for drainage and the placement of subdural drains. The patient was managed with the requisite medical therapies. Post-operatively, the patient regained consciousness and exhibited significant neurological improvement. Follow-up imaging demonstrated complete resolution of the subdural hemorrhage, and the patient achieved a full recovery of cognitive function. This case underscores the critical necessity for vigilant surveillance for delayed SDH in patients lacking initial radiographic findings and advocates for individualized therapeutic approaches in patients with concurrent pathologies. Prompt recognition, timely neurosurgical management, and care are pivotal to optimizing outcomes in delayed posttraumatic SDH cases.

Genetic variation in FOXP3 and ROR-γ genes in pediatric acute lymphocytic leukemia (ALL) patients: correlation with associated cytokines.

BACKGROUND: FOXP3 and ROR-γ genes are master regulators of the Treg and Th17 differentiation, respectively. This work was planned to investigate the impact of FOXP3 (rs3761548C/A and rs3761549C/T) and ROR-γ (rs9017A/G & rs9826A/G) gene polymorphism on the vulnerability of pediatric Egyptians to acute lymphoblastic leukemia (ALL). Furthermore, we evaluated the impact of these genetic variations on Treg/Th17-related cytokines. METHODS: FOXP3 SNPs were genotyped using PCR-based restriction fragment length polymorphism (PCR-RFLP), while ROR-γ SNPs polymorphism were performed by PCR-sequence-specific primer (PCR-SSP). An Enzyme-linked immunosorbent assay (ELISA) was used to assess the levels of Treg/Th17 associated cytokines on 128 ALL children and 124 healthy donors. RESULTS: Compared to controls, patients had a significant increase (p < 0.01/p < 0.05) in FOXP3rs3761548CC genotype and a significant decrease (p < 0.001/p < 0.01) inrs3761548CA genotype. A significant elevation (p < 0.001/p < 0.01) in ROR-γ rs9017AA genotype and a significant reduction (p < 0.01/p < 0.05) in rs9017AG genotype were detected in ALL patients versus controls. An insignificant change in FOXP3 (rs3761549C/T) and ROR-γ (rs9826A/G) genotypes was demonstrated between both groups. ROR-γ GG and GA haplotypes were significantly decreased (p < 0.05/p < 0.05; p < 0.05/p < 0.05) in ALL subjects compared to healthy ones. Relapsed patients had a significantly higher (p < 0.05/P < 0.05) frequency of FOXP3 rs3761548CA genotype than non-relapsed subjects. ROR-γ rs9017AG and rs9826GG genotypes might be associated with the increase in IL-23 plasma level. CONCLUSIONS: Our preliminary data provided evidence for the impact ofFOXP3 (rs3761548C/A) and ROR-γ (rs9017A/G) gene polymorphisms and the occurrence of ALL in Egyptian children. Another large-scale prospective study should be conducted to validate these findings.

Acute Generalized Exanthematous Pustulosis After COVID-19 Infection: A Case Report From Saudi Arabia.

There is a dearth of robust evidence regarding coronavirus disease 2019 (COVID-19)-related coetaneous manifestations, complications and adverse treatment events. Upon review of the literature there are only a few cases reported of acute generalized exanthematous pustulosis (AGEP) in COVID-19 patients after treatment. Therefore, we are reporting a case of a 34-year-old male not known to have any chronic illness. His severe COVID-19 infection resolved four days prior to presentation to the Emergency Department with pustular rash on erythematous base over his face, neck, upper limbs, anterior and posterior trunk including oral cavity and tounge. The rash started after he took azithromycin, oseltamivir, ribavirin, lopinavir, hydroxychloroquine, prednisolone, ceftriaxone, clindamycin, interferon (IFN) beta, and ceftazidime for COVID-19. Skin punch biopsy was done and he was diagnosed with AGEP but it was still not known if it was related to COVID-19 or a drug-induced condition. Patient was treated with betamethasone valerate 0.1% ointment and lotion, promethazine hydrochloride 25mg tablet, paracetamol 500mg tablet, calcipotriol 50mcg/g and betamethasone 0.5mg/g gel. He discharged the same day to manage at home despite not improving. In the end, we found only a few studies that describe the cutaneous manifestations of COVID-19 infection, which were mainly case reports. We can't be sure that AGEP is a late and severe complication of COVID-19 infection. However, AGEP could be a rare adverse effect of hydroxychloroquine therapy. Improving the knowledge about a wide range of different signs and symptoms of the disease and its severity in addition to all possible adverse treatment events and complications can improve patient safety, survival rate, and quality of life.

Regulation of CD4+CD25+FOXP3+ cells in Pediatric Acute Lymphoblastic Leukemia (ALL): Implication of cytokines and miRNAs.

Regulatory T cells (Tregs) is one of the immunosuppressive subsets of CD4+ T cells characterized by transcription factor forkhead box protein P3 (FOXP3) expression which are involved in tumor development and progression. Identification of the factors that influence Treg cell function is extremely important. Our current study aimed to evaluate the frequency of Treg cells, cytokine secretion and the expression of microRNAs (miRNAs) in pediatric acute lymphoblastic leukemia (ALL) patients. The frequency of CD3+, CD4+ and CD4+CD25+FOXP3+ Treg was assessed by flow cytometry in 43 ALL patients versus 42 controls. Plasma levels of IL-10, transcription factor ß (TGF-ß), IL-6, IL-17, IL-23 and tumor necrosis factor (TNF-α) were measured by Enzyme-linked immunosorbent assay (ELISA). miR-21, miR-24, miR-26a, miR133b, miR-148a and miR-155 expression were analyzed using quantitative real-time polymerase chain reaction (qRT-PCR). A slight insignificant increase in Treg cells in ALL patients compared to controls was observed. There was a significant elevation in IL-10 (p < 0.05), IL-6 (p < 0.01), IL-23 (p < 0.05) and TNF-α (p < 0.01) in ALL patients compared with controls. Meanwhile, a significant reduction in TGF-ß (p < 0.001) was recorded. A slight insignificant decrease in IL-17 in ALL patients was observed.ALL patients showed a significant increase in miR-21 (p < 0.05), miR-148a (p < 0.01), miR-24 (p < 0.05) and a significant reduction in miR-155 (p < 0.01). In conclusion, the slight change in Treg cells frequency and alteration in related cytokines could possibly involve in the pathogenesis of ALL. Dysregulated miRNAs, as a regulatory mechanism of epigenetics, might contribute to these observed results. Further researches are required to confirm our interesting findings.

Study protocol for a randomized, blinded, controlled trial of ketamine for acute painful crisis of sickle cell disease.

BACKGROUND: Sickle cell disease (SCD) is an inherited hematological disorder where the shape of red blood cells is altered, resulting in the destruction of red blood cells, anemia, and other complications. SCD is prevalent in the southern and eastern provinces of the Arabian peninsula. The most common complications for individuals with SCD are acute painful episodes that require several doses of intravenous opioids, making pain control for these individuals challenging. Instead of opioids, some studies have suggested that ketamine might be used for pain control in acute pain episodes of individuals with SCD. This study aims to evaluate whether the addition of ketamine to morphine can achieve better pain control, decreasing the number of repeated doses of opiates. We hypothesize that early administration of ketamine would lead to a more rapid improvement in pain score and lower opioid requirements. METHODS AND ANALYSIS: This study will be a prospective, randomized, concealed, blinded, pragmatic parallel group, controlled trial enrolling adult patients with SCD and acute vaso-occlusive crisis pain. All patients will receive standard analgesic therapy during evaluation. Patients randomized to the treatment arm will receive low-dose ketamine (0.3 mg/kg in 0.9% sodium chloride, 100 ml bag) in addition to standard intravenous hydration, while those in the control group will receive a standard dose of morphine (0.1 mg/kg in 0.9% sodium chloride, 100 ml bag) in addition to the standard intravenous hydration. All healthcare providers will be blinded to the treatment arm. Data will be analyzed according to the intention-to-treat principle. The primary outcome is improvement in pain severity using the Numerical Pain Rating Score. TRIAL REGISTRATION: Clinicaltrials.gov, NCT03431285 . Registered on 13 February 2018.

Preoperative use of romiplostim in thrombocytopenic patients with chronic hepatitis C and liver cirrhosis.

BACKGROUND AND AIM: Patients infected with hepatitis C virus (HCV) often develop chronic liver disease, liver cirrhosis and concurrent thrombocytopenia, which manifests as decreased platelet counts and bleeding complications. Romiplostim, a thrombopoietin mimetic peptibody that stimulates the thrombopoietin receptor, has been used as a treatment for primary immune thrombocytopenia. We monitored the efficacy of preoperative romiplostim over 90 days in 35 male patients with chronic hepatitis C, liver cirrhosis and thrombocytopenia secondary to HCV infection. METHODS: Romiplostim was administered at 2 µg/kg Q1W for a maximum of one month with a target platelet count of 70 × 10(9)/L as a prerequisite for planned surgeries. Bone marrow aspirate was collected at baseline and at the end of the study, along with liver and kidney function assessments. A complete blood count was performed every third day throughout the study period. RESULTS: A rapid response to romiplostim therapy was observed, with 33/35 patients achieving platelet counts ≥ 70 × 10(9)/L and thereby eligible for surgery. An initial mean platelet count of 31 × 10(9)/L increased to a maximum peak range of 73-240 × 10(9)/L, occurring between days 18 and 39. The reticulin bone marrow grade remained negative in all patients. Surgical interventions were associated with no postoperative bleeding or thrombotic complications. CONCLUSIONS: Preoperative romiplostim administration may represent a viable alternative to increase platelet counts to a level acceptable for elective surgical interventions in patients with chronic liver disease and severe thrombocytopenia secondary to HCV infection who are unresponsive to standard therapy. Further studies in larger numbers of patients and over a longer period of time are warranted.

LigaSure hemorrhoidectomy versus stapled hemorrhoidopexy: a prospective, randomized clinical trial.

PURPOSE: This study was designed to compare the outcome of LigaSure hemorrhoidectomy and stapled hemorrhoidopexy for prolapsed hemorrhoids. METHODS: Consecutive patients with grade III or IV hemorrhoids were randomly assigned to undergo either LigaSure hemorrhoidectomy or stapled hemorrhoidopexy. Data on patient demographic and clinical characteristics, operative details, postoperative pain score on a visual analog scale, number of parenteral analgesic injections, duration of hospital stay, and time to return to work were all prospectively collected. Postoperative complications and recurrence of prolapse were also recorded. Patients were regularly followed for a total period of 12 months. RESULTS: A total of 68 patients completed the study (34 per group). Patient demographic and clinical characteristics were similar in the 2 groups. No significant differences between LigaSure hemorrhoidectomy and stapled hemorrhoidopexy were observed in mean operating time, postoperative pain score, number of parenteral analgesic injections, duration of hospital stay, or time to return to work. The groups were also similar regarding postoperative complications, except that at 4 weeks postoperatively, residual prolapse was observed in 8 patients (23.5%) in the stapled hemorrhoidopexy group vs. 2 patients (5.9%) in the LigaSure group (P = .040). Rate of recurrence of prolapse at 1 year was higher with stapled hemorrhoidopexy (4 patients, 11.8%) than with the LigaSure procedure (1 patient, 2.9%), but the difference was not significant (P = .163). CONCLUSIONS: LigaSure hemorrhoidectomy and stapled hemorrhoidopexy yield comparable good results, with a short operative time and minimal side effects in the treatment of grade III and IV hemorrhoids, but with a lower rate of residual prolapse for the LigaSure procedure. Both procedures offer low levels of postoperative pain and therefore are excellent therapeutic options for prolapsed grade III and IV hemorrhoids. A larger controlled study is needed to reach solid conclusions regarding risk of postoperative recurrence of hemorrhoidal prolapse.

Stem cell transplantation in hematological disorders. A developing country experience-impact of cost considerations.

OBJECTIVE: To describe the experience in setting up a bone marrow transplant program at Ain Shams University, Cairo, Egypt. METHODS: Sixteen patients were transplanted at Ain Shams University Bone Marrow Transplantation unit from March 2005 to January 2008. RESULTS: Sixteen patients were transplanted with a median age of 25 years. Indications for transplantation were chronic myeloid leukemia, acute myeloid leukemia, aplastic anemia, acute lymphoblastic leukemia, and aggressive lymphoma. Seven donors and 6 patients were positive for cytomegalovirus immunoglobulin G (IgG) antibody (Ab) pretransplant. Only one patient was positive for toxoplasma IgG Ab and another had a high titre for toxoplasma IgM Ab pretransplant. Two donors and 2 recipients were positive for hepatitis B antibody markers; however, none were positive for hepatitis B virus DNA by polymerase chain reaction (PCR). None of the patients or donors were positive for hepatitis C virus via PCR pre-transplant. Acute graft versus host disease (GVHD) was seen in 3 patients, while chronic GVHD was seen in 5 patients. Primary cause of death was recurrence in 2 patients and graft failure in one patient. Thirteen are alive and disease free with a median follow-up of 20 months. CONCLUSION: Although our unit is a relatively new unit, these results are comparable to those achieved in the Western world and cost a mean of US$250,000.

Assessment of parathyroid autotransplantation for preservation of parathyroid function after total thyroidectomy.

BACKGROUND: Hypoparathyroidism with permanent hypocalcemia is a well-recognized complication after thyroid surgery. AIM: This study was conducted to assess the role of immediate parathyroid autotransplantation in the preservation of parathyroid function after total thyroidectomy. PATIENTS AND METHODS: Twenty-eight patients had autotransplantation of parathyroid glands resected or devascularized during total thyroidectomy. Data were collected prospectively regarding demographics, indication for surgery, operative procedure, pathologic diagnosis, number of glands transplanted, and subsequent course. Thyroid nodules were evaluated by ultrasonography, radionuclide scanning, and/or fine-needle aspiration cytology. All patients had serum ionized calcium, phosphorus, and intact parathyroid hormone (PTH) levels measured preoperatively and monitored regularly postoperatively for a period of 14 weeks and again at 6 months after operation. Patients were categorized into three groups according to the number of glands transplanted: one (group 1, n = 6), two (group 2, n = 14), or three glands (group 3, n = 8). In three other volunteers, one parathyroid gland was transplanted in the brachioradialis and subjected to electron microscopy 1, 2, and 4 weeks after transplantation. RESULTS: Total thyroidectomy was performed for malignant disease in 16 patients (57.1%) and for benign disease in 12 (42.9%) patients. All patients reverted to asymptomatic normocalcemia without the need for any medications within 4 to 14 weeks. Normal levels of serum markers were regained slower when one gland was transplanted compared with two or three glands (P <.01). Electron microscopic examination showed evidence of ischemic degeneration in the transplanted tissues 1 week postoperatively. Regeneration started by the second week and coincided with normalization of PTH levels. Optimum resting and nearly normal status of parathyroid tissue was achieved by the fourth week. CONCLUSIONS: This study showed that active PTH production coincides with regeneration of parathyroid cells and that autotransplantation of at least two resected or devascularized glands during total thyroidectomy nearly eliminates permanent postoperative hypoparathyroidism, thus improving the safety of total thyroidectomy performed for malignant or benign disease.
