Phenotypic, Electrophysiologic, and Imaging Spectrum of Hirayama Disease from Northern India.

Cervical flexion-induced myelopathy, also known as Hirayama disease (HD), is a lower motor neuron disorder seen mainly in adolescents and young adults, affecting the C7-T1 myotomes, presenting as asymmetric weakness with wasting of one or both the distal upper limbs. We aimed to describe the clinical features, electrophysiology, and radiologic features of HD in a tertiary care institute in northern India. One hundred and forty patients between 2017 and 2022 with clinical and imaging features consistent with HD were retrospectively reviewed from the All India Institute of Medical Sciences-Comprehensive Neuromuscular Diseases center database. Majority were males with the mean age of onset of illness being 17.8 years. The median duration of the symptoms was 3 (1.5-4) years. Sixty-nine (49%) patients had unilateral involvement, and the disease was actively progressing in 88 (63%) patients at presentation. Two families had history of HD in two (1.4%) siblings. Electromyography showed abnormal findings in the clinically involved limb in all the patients and in the clinically uninvolved limb in 17/50 (34%) patients. Flexion magnetic resonance imaging (MRI) demonstrated forward dural displacement in 134 (96%) patients and asymmetric cord flattening in 124 (88.5%) patients. Disability was graded as mild, moderate, and severe; 12 (13%) had severe disability. The majority were managed conservatively, and four underwent surgery for HD. A high index of suspicion of HD needs to be kept in a young male presenting with distal upper limb weakness and atrophy. Dynamic MRI of the cervical spine in young adults presenting with hand wasting is inevitable. This disease needs to be managed aggressively and early to prevent serious dysfunction and loss of productivity.

Transvaginal sonographic screening of abnormal intra-amniotic structure around internal cervical os at 18-21+6 weeks of gestation.

To detect an abnormal intra-amniotic structure around the internal cervical os using transvaginal sonography at 18-21+6 weeks of gestation. In this cohort study, during a 12-month period from July 2022 to June 2023, 395 transvaginal scans were performed for second-trimester cervical-length screening in singleton pregnancies at 18-21+6 weeks of gestation. Nine abnormal intra-amniotic structures (AIAS), 87 low-lying placentas (LLP, second-trimester placenta previa or placental margin within 2 cm from internal cervical os), and 299 controls (not LLP and no abnormal finding around internal cervical os) were diagnosed. Sonographic features of AIAS and delivery outcomes in the three groups were compared. Sonographic features of nine AIAS cases were: two single bands, one single broad band, one multiple bands, one single tubular, and one multiple tubulars. Blood flow was noted in seven cases. Seven AIAS had disappeared by 26 weeks, one was resolved at 34 weeks, and one (vasa previa and parachute placenta) remained until delivery. Incidences of emergency cesarean section, abnormal placenta and umbilical cord, and abnormal deliveries in AIAS were significantly higher than those in LLP and control groups (P = 0.031). Blood losses during delivery in AIAS and LLP groups were significantly greater than in the control group (P = 0.004), but there was no significant difference in blood loss between AIAS and LLP groups. The incidence of AIAS around the internal cervical os in the second trimester was 2.28% (9/395 fetuses). Mid-second-trimester transvaginal sonographic screening for the detection of AIAS around the internal cervical os including vasa previa may be essential to reduce perinatal morbidity.

Comparison of Urine and Cervical Samples for Genotyping Via HPV DNA Test

<i>Background</i>: Human papillomavirus (HPV) is a key factor in cervical cancer development. This study aimed to compare the efficacy of urine and cervical samples for HPV genotyping, evaluating their diagnostic performance in detecting high-risk HPV genotypes. <i>Methods</i>: This comparative cross-sectional study conducted over one year at the Department of Gynaecological Oncology, BSMMU, Dhaka, the study enrolled 74 women aged 30-60 years with positive visual inspection with acetic acid (VIA) results or abnormal Pap test findings. Urine samples (20 ml) and cervical samples were collected from each participant. The samples were analyzed using multiplex real-time PCR to amplify high-risk HPV types (16, 18, and others). DNA was extracted using the Qiagen viral DNA extraction kit. Sensitivity and specificity of HPV detection in urine samples were compared to cervical sampling, the gold standard. Data were analyzed with SPSS 22.0, and agreement was assessed using the Kappa index. <i>Result</i>: Cervical samples detected HPV in 17.56% of participants, while urine samples identified HPV in 5.40%. The agreement between urine and cervical samples was moderate, with a kappa value of 0.743. Among 74 cases, 5 cases were detected as HPV 16 and HR (co-injection) in both cervical and urine sample, 2 cases as HPV 16 in both cervical and urine samples, 2 cases as only HR type in both cervical and urine sample. The kendall’s correlation of agreement was 0.361 and a significance of 0.002. <i>Conclusion</i>: Cervical samples are more reliable for HPV detection compared to urine samples, though urine testing shows high sensitivity.

The TELEhealth Shared decision-making COaching and navigation in Primary carE (TELESCOPE) intervention: a study protocol for delivering shared decision-making for lung cancer screening by patient navigators.

Lung cancer screening (LCS) can reduce lung cancer mortality but has potential harms for patients. A shared decision-making (SDM) conversation about LCS is required by the Centers for Medicare & Medicaid Services (CMS) for LCS reimbursement. To overcome barriers to SDM in primary care, this protocol describes a telehealth decision coaching and navigationintervention for LCS in primary care clinics delivered by patient navigators. The objective of the study is to evaluate the effectiveness of the intervention and its implementation potential, compared with an enhanced usual care (EUC) arm. Patients (n = 420) of primary care clinicians (n = 120) are being recruited to a cluster randomized controlled trial. Clinicians are randomly assigned to 1) TELESCOPE intervention: prior to an upcoming non-acute clinic visit, patients participate in a telehealth decision coaching and navigationsession about LCS delivered by trained patient navigators and nurse navigators place a low-dose CT scan (LDCT) order for each TELESCOPE patient wanting LCS, or 2) EUC: patients receive enhanced usual care from a clinician. Usual care is enhanced by providing clinicians in both arms with access to a Continuing Medical Education (CME) webinar about LCS and an LCS discussion guide. Patients complete surveys at baseline and 1-week after the scheduled clinic visit to assess quality of the SDM process. Re-navigation is attempted with TELESCOPE patients who have not completed the LDCT within 3months. One month before being due for an annual screening, TELESCOPE patients whose initial LCS showed low-risk findings are randomly assigned to receive a telehealth decision coaching booster session with a navigator or no booster. Electronic health records are abstracted at 6, 12 and 18months after the initial decision coaching session (TELESCOPE) or clinic visit (EUC) to assess initial and annual LCS uptake, imaging results, follow-up testing for abnormal findings, cancer diagnoses, treatment, and tobacco treatment referrals. This study will evaluate factors that facilitate or interfere with program implementation using mixed methods. We will assess whether a decision coaching and patient navigation intervention can feasibly and effectivelysupport high-quality SDM for LCS and guideline-concordant LCS uptake for patients in busy primary care practices serving diverse patient populations. This study was registered at ClinicalTrials.gov (NCT05491213) on August 4, 2022. Version 1, April 10, 2024.

Evaluation of acute and subacute dermal toxicity of antibacterial bioactive glass-infused surgical cotton gauze in Wistar rats

Mesoporous bioactive glass, with its versatile characteristics and morphology, holds significant potential as an ideal hemostatic material. However, limited data is available regarding its toxicity levels. Consequently, this research intends to assess the acute and repeated dose dermal toxicity of Mesoporous antibacterial bioactive glass microsphere impregnated nonwoven surgical cotton gauze (MABGmscg) dressing in albino Wistar rats, following the standards set by the Organization for Economic Cooperation and Development. In the acute dermal toxicity study, the impact of MABG (@2000mg/kg BW) mscg dressing was assessed following a single dermal application in both male and female Wistar rats (n = 10). Mortality, clinical signs, body weight fluctuations and gross observations were consistently monitored over a14 day period following the single dose. The results indicated that, MABG (@2000mg/kg BW) mscg dressing upon dermal exposure did not cause any adverse effect in acute dermal toxicity study in Wistar rats compared to control group. Given that 2000 mg/kg BW of MABG was deemed a nontoxic dose, a repeated dose dermal toxicity study of MABGmscg dressing was subsequently conducted at three dose levels (@200, 500, 1000 mg/kg BW) over 28 consecutive days in Wistar rats. During the study period, no unscheduled deaths occurred, and there were no clinical signs associated with treatment, body weight variations or abnormal gross findings at necropsy in any groups. The analysis concluded that, MABGmscg dressing is safe to be considered as a hemostatic dressing at the various tested dose levels in Wistar rats.

Esophagitis, treatment outcomes, and long-term follow-up in children with esophageal atresia.

Survival rates in children born with esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) have improved; however, morbidity associated with the disease remains high. This study aimed to assess the prevalence of gastroesophageal reflux disease (GERD), eosinophilic esophagitis (EoE), fungal esophagitis, esophageal strictures, and long-term outcomes in children with EA/TEF. We conducted a retrospective chart review on patients with EA/TEF who were seen at Children's Wisconsin from January 2003 to January 2023. Patients born with EA/TEF were included if they underwent at least one endoscopy after 1 year of age. GERD was diagnosed based on abnormal findings on endoscopy, pH-metry, and/or history of fundoplication. EoE and fungal esophagitis were diagnosed based on abnormal endoscopy. Esophageal stricture diagnosis was based on findings on endoscopy and/or esophagram, and clinical symptoms necessitating esophageal dilation. Eighty-five patients (64.7% males, mean age 7.5 years) were included, the majority had type C EA/TEF (90.6%). GERD was diagnosed in 61.1% (n = 52), 49.4% (n = 42) by macro and/or microscopic endoscopic findings, 22.3% (n = 19) by abnormal pH-metry, and 21.1% (n = 18) by the need for fundoplication for refractory reflux and/or esophageal stricture. Risk of GERD increased with lower gestational age (p = 0.0030), lower birth weight (p = 0.023), and long-gap EA (p = 0.034). In children diagnosed with GERD, only 13.4% of patients (n = 7/52) were able to be weaned off proton pump inhibitor (PPI) without disease recurrence. However, overall, at the completion of the study, 44.7% (n = 38) of patients were successfully weaned off PPI without evidence of GERD. EoE was diagnosed in 20% of the patients (n = 17). All patients diagnosed with EoE required escalation of therapy from PPI alone to swallowed corticosteroids in 52.9% (n = 9), dupilumab in 23.5% (n = 4), elemental formula in 17.6% (n = 3), and elemental formula and swallowed steroids in 5.8% (n = 1). Fungal esophagitis was diagnosed in 15.3% of patients (n = 13). An esophageal stricture requiring dilation was diagnosed in 77.6% (n = 66) of patients at a mean age of 28.5 months, with over 60% diagnosed by 24 months of age. Children born with EA/TEF continue to be at high risk of developing GERD, EoE, fungal esophagitis, and esophageal stenosis. Diagnostic and therapeutic endoscopy remains a high-yield test to identify and treat these comorbidities.

Hepatocellular Changes on Paracetamol Induced Liver Damage in Long Evans Male Rats upon Green Tea Administration

Background: The liver is a vital organ that serves a number of purposes in our body. It may be harmed by pollutants, substances with toxic effects, and long-term, unchecked drug use. Green tea is a well-liked beverage that has gained popularity recently and may have hepatoprotective properties. Objective: To observe the effect of green tea (Camellia sinensis) on paracetamol induced liver damage in Long Evans male rats. Methods: From July 1st, 2018, to June 30th, 2019, this study was conducted in the Department of Physiology at Sir Salimullah Medical College (SSMC), Dhaka. For the purpose of the study, thirty (30) male Long Evans rats, weighing between 150 and 200 grams and 90 to 120 days old, appeared to be in good health. They were split into two groups after 14 days of acclimatization: Group A, which served as the control group, and Group B, which served as the experimental group (green tea pretreatment and paracetamol treated). Group A1 (baseline control group) and group A2 (paracetamol treated control group) comprised the subdivided control group. There were ten rats in each of these groups. For 28 days, the rats were all fed a baseline diet. The baseline control group was given normal saline (20 ml/kg/day) orally every day for 28 days in addition to their basal diet. For the final three days of the study—the 26th and 28th—the paracetamol-treated control group was given oral paracetamol at a dose of 1.5 g/kg/day. During the final three days of the study period (the 26th and 28th days), the experimental group was given oral paracetamol (1.5g/kg/day) and an ethanolic extract of green tea (500 mg/kg/day) for a total of 28 days. On day 29, every rat was sacrificed. Following the sacrifice, liver samples were taken. Hepatic contents of malondialdehyde (MDA) were measured by using standard laboratory method. Histopathology of liver was also done by using standard laboratory procedure in the department of pathology, SSMC. Version 22 of the Statistical Package of Social Science (SPSS) for Windows was used to do the statistical analysis. The data were displayed as mean±SD. To compare the results, one-way ANOVA, post hoc Bonferroni, and Chi-square tests were used, where appropriate. A p value of less than 0.05 was regarded as significant. Result: When compared to the baseline control group, the mean malondialdehyde concentration in the liver was significantly (p) greater in the green tea pretreatment, paracetamol treated, and control groups who received paracetamol treatment. Once more, the groups treated with green tea and paracetamol had mean malondialdehyde concentrations in their livers that were significantly (p) lower than those of the paracetamol group. Additionally, 0% of the rats in the baseline control group, 100% of the rats in the paracetamol-treated group, and 30% of the rats in the green tea-pretreated and paracetamol-treated group had abnormal histological findings of the liver. Conclusion: This study revealed that green tea has hepatoprotective effect against paracetamol induced liver damage in Long Evans male rats. Bangladesh Crit Care J September 2024; 12 (2): 145-152

Clinical assessment of small bowel capsule endoscopy in pediatric patients.

Small bowel capsule endoscopy is a first-line examination method for small bowel diseases, which can find small intestinal lumen and mucosal lesions. We retrospectively assessed patients who underwent small bowel capsule endoscopy between September 2020 and May 2023 to examine their clinical and small bowel capsule endoscopic data, aiming to provide insights into the application of this technique in pediatric patients with small intestinal diseases. All instances of capsule retention were successfully resolved through enteroscopy. Of the 1140 children who completed the capsule endoscopy, 97.46% (1111/1140) underwent a comprehensive examination of the entire small intestine without experiencing any discomfort. Capsule endoscopy yielded abnormal findings in 672 cases, with a positive detection rate of 58.95%. Among the positive results, intestinal mucosal inflammatory lesions were the most prevalent, occurring in 292 cases (43.45%), followed by ulcerative or erosive lesions in 236 cases (35.12%), diverticulum in 54 cases (8.04%), and vascular lesions in 30 cases (4.46%). Lymphangiectasis was observed in 16 cases (2.38%). The distribution of positive lesions did not exhibit significant gender-based differences, but there were variations among different age groups. Among all children who completed the small bowel capsule endoscopy, the most frequently reported symptom was abdominal pain (815/1140 cases, 71.49%), followed by 130 cases (11.40%) of bloody stools or melena. Small bowel capsule endoscopy is well-tolerated and safe in children, carrying significant clinical importance for diagnosing abdominal pain and obscure gastrointestinal bleeding in pediatric patients.

Solid-basaloid Variant of Mammary Adenoid Cystic Carcinoma – Report of an Unusual Case with Literature Review

Abstract Introduction/Objective Adenoid cystic carcinoma (AdCC) of breast is a rare subtype of malignancy, constituting approximately 0.1% of all breast carcinomas. The solid-basaloid variant (SB-AdCC) is exceedingly uncommon. Here, we present such an unusual case of SB-AdCC. Methods/Case Report A 64-year-old woman who underwent screening mammography presented with abnormal findings, revealing a hypoechoic ovoid, lobulated nodule at 7:00 of the left breast, which prompted an ultrasound- guided biopsy. Histologically, the biopsy cores demonstrated a 9 mm infiltrative round, solid nests with focal “cribriforming” areas. It was composed of monomorphic basaloid epithelial cells with marked nuclear atypia and high mitotic count. High-grade ductal carcinoma in situ, solid papillary carcinoma, and nonspecific invasive carcinoma were in differentials. Immunohistochemical (IHC) staining expressed positivity for CD117 and CK 5/6, while p63, SMMHC, and synaptophysin were negative. MYB gene rearrangement confirmed by fluorescence in situ hybridization. As expected, the tumor lacked ER, PR, and HER2 expression by IHC. Left breast mastectomy and axillary lymph node dissection have been scheduled. Results (if a Case Study enter NA) NA Conclusion Per literature review, the mean age of SB-AdCC at diagnosis was 68 years (33-84 years) with an average tumor size of 25 mm (12-70 mm). It had more aggressive behavior, with a higher propensity for lymph node metastasis, locally recurrence, and distant metastasis. The median disease-free survival was 46.5 months versus 151.8 months in those with class AdCC. Notably, neovascularization has emerged as a strong independent predictor of outcome in SB-AdCC. Most patients were treated with surgical excision, axillary lymph node dissection, and/or adjuvant chemotherapy. Limited studies demonstrated that neoadjuvant chemotherapy may induce an excellent response. Furthermore, a distinct molecular mutation enriched in NOTCH and CREBBP genes has been identified, which could be novel potential therapeutic target. Thus, awareness of this extremely rare breast cancer subtype and accurate differentiation from other entities are paramount for appropriate management strategies.

Eosinophilic gastroenteritis, a rare case report and literature review

Abstract Introduction/Objective Eosinophilic gastroenteritis (EGE) is a rare inflammatory condition affecting the gastrointestinal tract, initially described by Kaijser et al. in 1937. It manifests as eosinophil-rich infiltration throughout the GI tract, often accompanied by peripheral eosinophilia. EGE is categorized under eosinophilic gastrointestinal disorders (EGIDs), alongside eosinophilic esophagitis (EOE) and eosinophilic colitis (EC). Symptoms vary based on the affected GI segment. This report aims to present a case of extensive EGE in a young male patient and review of similar cases to enhance clinical and histopathologic understanding. Methods/Case Report A 29-year-old male presented with abdominal pain, nausea, vomiting, and recent weight loss. He had a history of similar abdominal symptoms for a few years. Previous extensive investigations were inconclusive. Current imaging revealed soft tissue nodules, mild splenomegaly, and biliary dilation. Laboratory tests showed no significant abnormalities. Endoscopy revealed a gastric antral ulcer with marked eosinophilic infiltration on microscopy. Results (if a Case Study enter NA) NA Conclusion Eosinophilic gastroenteritis is an uncommon disease that presents with variable non-specific symptoms which require a high level of suspicion for diagnosis. EGE diagnosis requires excluding other causes of eosinophil accumulation. There is no clear distinction between the upper normal and abnormally increased eosinophils in GIT biopsies. Peripheral eosinophilia is common, along with other abnormal laboratory findings. Diagnosis relies on histopathology due to nonspecific symptoms. Clinicians and pathologists face challenges in diagnosing EGE, emphasizing the importance of considering it in the differential diagnoses. Efforts to establish diagnostic criteria for EGE are limited, despite its long-known existence. The condition’s vague symptoms necessitate a high level of clinical suspicion, with diagnosis primarily based on histopathologic features.

Multisystem ALK-Positive Histiocytosis With DCTN1::ALKFusion in an Adult, Responsive to Alectinib: Case Report and Literature Review.

Anaplastic lymphoma kinase (ALK)-positive histiocytosis has emerged as a clinically relevant diagnosis featuring a wide span of clinical presentations, which are unified by the presence of ALK-positive histiocytes on histopathology and molecular drivers involving the ALK kinase gene. This report presents an adult case of multisystem ALK-positive histiocytosis with xanthogranuloma-like features on histopathology that was responsive to ALK inhibition, and includes a review of ALK-positive histiocytoses with cutaneous involvement reported in the literature. A 56-year-old male developed a widespread eruption of red-brown papules on the face, trunk, and upper extremities. Histopathological evaluation revealed a well-circumscribed, nodular dermal infiltrate of epithelioid histiocytes with Touton giant cells, rare bizarre multinucleated cells, and focal emperipolesis. The lesional cells were positive for CD68 and ALK1 immunohistochemical stains, and negative for CD1a. Next-generation sequencing identified a DCTN1::ALK fusion. On imaging, he was found to have bone, lung, soft tissue, and salivary gland involvement. ALK inhibition was initiated with alectinib, resulting in rapid improvement of cutaneous lesions and eventual complete resolution of abnormal imaging findings, which was sustained at 24 months of follow-up. This case adds to the spectrum of ALK-positive histiocytoses and further demonstrates the positive response with targeted therapy.

Beyond the Surface: Uncovering the PML::RARA Fusion in Cytogenetically Cryptic and FISH-Negative Acute Promyelocytic Leukemia- A Case Report and Review of the Literature

Abstract Introduction/Objective Chromosomal t(15;17)(q22;q21), resulting in a fusion between the PML gene on chromosome 15q22 and the RARA gene on chromosome 17q21, is the cytogenetic hallmark of acute promyelocytic leukemia (APL). Conventional karyotyping, along with fluorescence in situ hybridization (FISH), can detect the PML/RARA rearrangements in up to 98% of APL cases. Reverse transcriptase-polymerase chain reaction (RT-PCR) is often used to confirm the initial diagnosis. APL with PML::RARA fusion, which is negative with FISH and conventional karyotyping approaches but positive with RT-PCR, is extremely rare. Herein, we report a de novo APL case that was positive by RT-PCR but negative by cytogenetics and FISH studies. A comprehensive review of the literature was also performed. Methods/Case Report A 23-year-old male presented to the ED for left upper extremity weakness 2 days after post- dental cleaning. Upon admission, he developed intracranial hemorrhage, necessitating urgent decompressive hemicraniectomy. Blood smear revealed promyelocytes; flow cytometric analysis showed a CD13+, CD33+, MPO+, CD117+, CD34-, and HLA-DR- abnormal cell population. STAT interphase FISH analyses for PML/RARA fusion and RARA break-apart were negative. A diagnosis of APL was made based on abnormal promyelocytes and characteristic flow cytometry findings. ATRA was immediately administrated. However, the post-operative course was complicated by significant coagulopathy, pancytopenia, and multi-organ failure, and the patient expired 7 days later. RT-PCR returned positive for PML::RARA long fusion transcript; the conventional cytogenetics study was uninformative. The clinical, pathological, and genetic features of 31 cases of FISH/Cytogenetics-negative APL harboring cryptic rearrangements of PML-RARA, detected by RT-PCR in the literature, have been reviewed. Various detection methods were also discussed. Results (if a Case Study enter NA) N/A Conclusion Conventional cytogenetics, FISH and RT-PCR analysis are complementary studies for all clinical suspected APL cases. The clinicopathological characteristics also play critical roles in APL diagnosis when genetic confirmation of the PML::RARA fusion is unavailable.

Utility of digital cell imaging as an aid to enhance pathologist peripheral blood smear review for routine and on call practice: A verification study

Abstract Introduction/Objective Microscopic examination of peripheral blood smear (PBS) provides important information to support the diagnosis of hematological diseases. However, manual microscopic examination of PBS is labor-intensive and cannot be done remotely. CellaVision is digital cell imaging technology that provides pre-classification and digital imaging of the red blood cells (RBCs), white blood cells (WBCs), and platelets, myeloid, lymphoid and erythroid precursors. Several studies have evaluated the performance of this technology in the hematology laboratory as tool to assist laboratory technologists; our study evaluates its use for pathologist review of peripheral blood smears both during routine and on call practice. Methods/Case Report Our study included 30 PBS and two hematopathologists with greater than 10 years’ experience in performing PBS review. We compared pathologist’s own impression of microscopic PBS review to their own impression using CellaVision software (intraobserver comparison). Additionally, pathologist to pathologist impression was compared for both methods (interobserver comparison). All 30 cases revealed abnormal findings including, but not limited to: pancytopenia, leukocytosis, leukopenia, anemia, thrombocytopenia, and thrombocytosis. Of the 30 cases, 5 “on-call” were cases when the pathologist had to come on–site for pathologist PBS review. Results (if a Case Study enter NA) The pathologists own PBS interpretation (intraobserver) by microscopy and CellaVision had a concordance of 96.7%. The pathologist to pathologist interpretation of both methods had a concordance of 96.7%.The one discrepant case was a smear with platelet clumping and normal platelet count. On chart review of this case, this discrepancy would have minimal impact on patient care. Conclusion Pathologist use of CellaVision in their routine practice may result in speedier PBS review, particularly in cases with leukopenia, and better communication with laboratory technologists. CellaVision is less reliable in identifying platelet clumps and should not be used in isolation in evaluating thrombocytopenia. Used with other relevant data, CellaVision has the potential to preempt in person microscopic review of PBS when on-call in certain situations.

Patterns of upper gastrointestinal diseases among patients undergoing esophagogastroduodenoscopy at three hospitals in Asella town, Southeast Ethiopia

Upper gastrointestinal (UGI) symptoms are among the common complaints among patients visiting health facilities. Because of the scarcity of gastrointestinal endoscopy services and gastroenterologists, the pattern of common upper gastrointestinal diseases has not been well studied in the study setting. This study aimed to determine the pattern of upper gastrointestinal diseases among patients undergoing esophagogastroduodenoscopy (EGD). An institution-based cross-sectional study was conducted at three hospitals in Asella town, southeast Ethiopia. A total of 279 study subjects were included in the study. Three-fourths (74%) of the study participants had abnormal endoscopic findings. The clinical indications for endoscopic examination were dyspepsia (32.6%), peptic ulcer disease (PUD) (27.2%), suspicion of gastric cancer (13.3%), and suspicion of esophageal cancer (11.5%). The abnormal endoscopic findings were esophageal cancer (10.4%), gastric cancer (10%), duodenal ulcer (DU) (9.3%), and gastritis (8.6%). The abnormal biopsy findings were esophageal cancer (7.5%), gastric adenocarcinoma (6.4%), and gastritis (3.9%). Dyspepsia, peptic ulcer disease, and suspicion of UGI malignancies were the most common clinical indications for endoscopic examination, while esophageal cancer and gastric cancer were the most common abnormal endoscopic findings. The most common abnormal biopsy results were esophageal squamous cell carcinoma and gastric adenocarcinoma. It is advised to have a high index of suspicion for esophageal cancer and gastric cancer for patients who present with alarming upper gastrointestinal symptoms in the study setting.

Genotoxicity and safety profile of Eleview®: A submucosal injectable composition for endoscopic mucosal resection and endoscopic submucosal dissection

Background and Objectives: Eleview® submucosal injectable composition with methylene blue (MB), is intended for use in gastrointestinal endoscopic procedures. Given the recognised in vitro mutagenicity of MB, Eleview® mutagenic and genotoxic potentials and its safety profile in acute and subacute toxicity settings were assessed. Methods: Acute and subacute systemic toxicity were tested in rats and dogs, respectively. Ames test and chromosome aberration test in Chinese Hamster V79 cells, were performed. The ratio of polychromatic to normochromatic erythrocytes was assessed in rat bone marrow at the rat MTD. Results: Eleview® oral or intraperitoneal at 20 mL/kg or 50 mL/kg did not induce any acute toxic effects in rats. In dogs, Eleview® (15 mL) did not cause any relevant in-life observations or any histopathological changes in any organs/tissues or injection sites. Ames test demonstrated no concentration-related and reproducible increases in revertant colony numbers. No significant increase of chromosomally aberrant cells was noted in Chinese Hamster cells. Lastly, Eleview® did not elicit significant increase in micronucleated polychromatic erythrocyte frequency. Conclusion: No death or abnormal findings in the acute and subacute studies were observed for Eleview® administration. Eleview® is not genotoxic, nor mutagenic, proving to be a safe medical device to use in clinical practice.

Hepcidin levels, markers of iron overload, and liver damage in children with beta-thalassemia major

Background Thalassemia is a hemoglobin synthesis disorder that causes patients to need lifelong blood transfusions, leading to iron overload and alter organ function, including the liver. Hepcidin, produced by the liver, plays a role in iron homeostasis and should be increased in excess iron stores. However, the level decreases in thalassemia due to some factors, such as ineffective erythropoiesis and liver damage. Recent publications revealed that hepcidin could be associated with iron overload and also a marker of liver diseases. Objective To analyse the correlation between hepcidin level, markers of iron overload, and liver damage in beta-thalassemia major. Methods This cross-sectional study included all ?-thalassemia major age 2-18 years admitted to Dr. Mohammad Hoesin Hospital, Palembang, South Sumatera, who underwent blood transfusions from March to August 2022. We measured the level of iron overload markers, hepcidin, liver function test (LFT), and performed liver ultrasonography (USG). Results Of 97 subjects, median hepcidin level was 10.01 ng/mL and 68% of the subjects showed a decrease. The iron overload parameters were evaluated from serum iron levels (P=0.13), ferritin levels (P=0.90), and transferrin saturation (P=0.29) and 24.7% had abnormal liver USG findings. Spearman’s correlation revealed that only direct bilirubin (DB) (r=0.35; P=0.001) and liver USG (r=0.20; P=0.05) had positive correlations with decreased levels of hepcidin. Also, it had 91.7% sensitivity in predicting liver damage from ultrasound. Conclusion The hepcidin level was not significantly associated with iron overload markers.

Magnitude of cardiac abnormality and its associated factors among hyperthyroidism patients on follow-up at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia

BackgroundThyroid hormones have an effect on every organ system, in particular, the heart responds to minimal changes in serum thyroid hormone level. Thyroid hormone causes a lot of changes in the cardiovascular system, such as increased heart rate, contractility, systolic hypertension, changes in peripheral vascular resistance, atrial fibrillation (AF), and hypercoagulability from the direct effect of thyroid hormone on cardiac myocyte and /or due to increased metabolic state. However, the magnitude of such heart abnormalities and its associated factors were not well studied in Ethiopia.ObjectiveTo determine the magnitude of cardiac abnormality and its associated factors among hyperthyroidism patients on follow-up at Tikur Anbessa Specialized Hospital (TASH), Addis Ababa, Ethiopia, 2022.MethodsAn institution-based cross-sectional study was carried out among 318 hyperthyroid patients who were on follow-up at the endocrine clinic of TASH, Addis Ababa, Ethiopia from June to October 2022. The data were collected using a pretested structured interviewer administered questionnaire. The data were entered into the computer using EpiData version 3.1 and analyzed using SPSS version 25 software. Bivariable and multivariable logistic regression models were fitted to determine the association between the independent and dependent variables. Adjusted odds ratio with its 95% confidence interval and p-value < 0.05 were used to declare the presence and strength of statistically significant associations.ResultIn this study a total of 318 hyperthyroid patients were participated, most (90.9%) of them were females. The overall prevalence of heart failure among hyperthyroid patients was 17.0% (95% CI = 13.0, 21.6). More than half (52.7%) and one third (33.2%) of the participants showed abnormal electrocardiographic and echocardiographic findings respectively. Marital status (not married) [AOR = 2.37, 95% CI (1.03, 5.44)], pattern of hyperthyroidism [AOR = 13.09, 95% CI (4.70, 36.41)], being Asthmatic [AOR = 7.63, 95% CI (1.55, 37.52)], type of medication [AOR = 3.49, 95% CI (1.11, 11.02)] and duration of treatment [AOR = 4.95, 95% CI (2.05,11.99)] were significantly associated with cardiac abnormality.ConclusionA significant portion of hyperthyroid patients overburdened by cardiac abnormalities. Being unmarried, overt hyperthyroid, Asthmatic, long stay on treatment and type of treatment were significantly associated with cardiac abnormality. Hence, attention should be given for cardiac abnormalities while treating hyperthyroid patients.

The diagnostic performance of neck ultrasound in follow-up of advanced stage differentiated thyroid cancer

BackgroundDifferentiated thyroid cancer (DTC) requires long-term follow-up due to the risk of delayed recurrence. Follow-up surveillance involves serial neck ultrasound (US) and thyroglobulin (Tg); however, the optimal frequency and diagnostic performance of neck US outside of specialized thyroid cancer centres in higher risk patients is not well defined. We sought to evaluate the diagnostic performance of US and serial Tg in advanced stage DTC.MethodsWe retrospectively reviewed our thyroid cancer database for patients with stage III and IV DTC from 2006 to 2018, total thyroidectomy, and at least 2 years follow-up to assess recurrence rates. Those with hemi-thyroidectomy or anti-Tg antibodies were excluded. Diagnostic performance of US and Tg were assessed using a composite reference standard of follow-up imaging and pathology. All relevant US were reviewed by a blinded expert radiologist for uniformity.ResultsOf 136 included patients (91 females, mean age 58.9), 26 (19%) had recurrence of DTC over median follow-up of 6.6 years (IQR 5.3–9.3). The sensitivity and specificity of US in diagnosing cervical recurrence were 73.3% (95% CI 0.51–0.96) and 68.3% (95% CI 0.60–0.77) based on historical reports, respectively, and 80% (95% CI 0.60-1.00) and 87.8% (95% CI 0.82–0.93) based on blinded expert review, respectively. Tg had a sensitivity of 95.5% (95% CI 0.89-1.0) and specificity of 96.2% (95% CI 0.92–0.99) in detecting cervical recurrence or distant metastases. False positive US findings on historical US and subsequent review occurred in 38 (28%) and 15 (11%) patients, respectively, while 5 (3.6%) had false positive Tg results.ConclusionSerial Tg has better sensitivity and specificity than US for detecting recurrence of advanced stage DTC. Furthermore, re-interpretation of abnormal findings using structured US reporting with a subspecialized reader may improve diagnostic performance of US and improve its utility in clinical care.

Low field magnetic resonance imaging of palmar osteochondral fragmentation of the distal phalanx

SummaryBackgroundThe presence of palmar osteochondral fragments of the distal phalanx is a newly recognised cause of foot lameness with only a few cases having been reported.ObjectivesTo describe the low field magnetic resonance imaging (MRI) appearance of palmar articular fragmentation of the distal phalanx and concurrent abnormalities of the distal interphalangeal joint (DIPJ); to investigate the prevalence of these fragments in a population of sports and pleasure horses and their potential clinical significance.Study designRetrospective descriptive case series.MethodsThis is a retrospective descriptive case series in which all Sports and Pleasure horses undergoing standing low‐field MRI of the feet between 2015 and 2023 were reviewed. Appearance, location and number of palmar articular fragments were recorded. When a palmar fragment was present, abnormal findings of the DIPJ were graded.ResultsA total of 855 horses underwent MRI examination of one or both front feet. Palmar osteochondral fragmentation of the distal phalanx was identified in four horses (0.4% prevalence), three Lusitanos and one Warmblood. The age range was 4–17 years old. All fragments were located along the palmarolateral margin of the glenoid of the distal phalanx in front feet. Concurrent imaging abnormalities of the joint were present in all four horses.Main limitationsLack of histopathology.ConclusionsThe prevalence of palmar articular fragments of the distal phalanx was low in this population of horses. Palmar osteochondral fragmentation must be considered when evaluating lameness localised to the foot, since it was identified only in lame limbs and associated with other imaging abnormalities of the DIPJ.

Predictors of Abnormal MRI Findings in Patients with Asymmetrical Sensorineural Hearing Loss.

This study aimed to determine the predictive factors of abnormal MRI findings in patients with asymmetrical sensorineural hearing loss (ASNHL). A retrospective review of medical records. A tertiary care hospital. Patients with asymmetries of ≥10 dB in at least 1 frequency, who underwent an MRI study of the temporal bone or brain during 2019-2021, were included. Age, sex, clinical symptoms, past medical history, and audiometric parameters, including pure tone thresholds, speech reception thresholds, and speech discrimination scores, were retrieved from the electronic database. The MRI findings reported by radiologists were reviewed and extracted. Of 390 patients, 50 (12.8%) patients had relevant abnormal MRI findings that could explain ASNHL. The most prevalent abnormal MRI finding was an internal acoustic canal (IAC) or cerebellopontine angle (CPA) tumor (n = 38; 76.0%), with other notable abnormalities including labyrinthitis, stroke, mucocele, and epidermoid. Multiple logistic regression analysis highlighted that hearing asymmetry of 15 dB at 1000 Hz (OR = 4.8; 95% CI 2.2-10.5) was a significant variable. The proposed predictor demonstrated 84% sensitivity and 48% specificity in detecting abnormal MRI findings. A hearing asymmetry of 15 dB at 1000 Hz was an important clinical predictor of abnormal MRI findings in patients with ASNHL. This finding has the potential to serve as a referral guide for further MRI investigations. Level 3 Laryngoscope, 2024.
