Spatial distribution and health risks assessment of heavy metals in e-waste dumping sites from Pakistan.

The present study focused on to determine the concentration and health risk of heavy metals (Cu, Pb, Zn, Cd, Hg, Cr) in e-waste contaminated soils collected from different provinces of Pakistan. Further, the impact of heavy metals on soil enzyme activities and microbial community was also investigated. The concentration (mg/kg) of Hg, Zn, Fe, Cu, Pb, Cd, and Cr ranged between 0-0.258, 2.284-6.587, 3.005-40.72, 8.67-36.88, 12.05-35.03, 1.03-2.43, and 33.13-60.05, respectively. The results revealed that Lahore site of Punjab province indicated more concentration of heavy metals as compared to other sites. The level of Cr at all sites whereas Hg at only two sites exceeds the World Health Organization standards (WHO) for soil. Soil enzyme activity exhibited dynamic trend among the sites. Maximum enzyme activity was observed for urease followed by phosphatase and catalase. Contamination factor (Cf), Pollution load index (PLI), and geo-accumulation index (Igeo) results showed that all the sites are highly contaminated with Cu, Cd, and Pb. Hazard index (HI) was less than 1 for children and adults suggesting non-carcinogenic health risk. Principle component analysis results depicted relation among Cr, Fr, catalase, and actinomycetes; Cd, OM, urease, and bacteria, and Pb, Cu, Zn, Hg, and phosphatase, suggesting soil enzymes and microbial community profiles were influenced by e-waste pollution. Therefore, there is a dire need to introduce sustainable e-waste recycling techniques as well as to make stringent e-waste management policies to reduce further environmental contamination.

Co-occurrence of Tuberculous Meningitis and Intestinal Perforation in Abdominal Tuberculosis (TB): A Report of a Rare Case From Pakistan.

Tuberculosis (TB) remains a significant global health concern, with millions affected worldwide each year. Extrapulmonary TB, particularly involving the digestive tract and central nervous system, poses distinctive difficulties in both diagnosis and treatment. We report a case involving a 15-year-old girl with a history of intestinal TB on anti-tuberculous therapy who presented with symptoms suggestive of meningitis, along with abdominal pain and distension. Our initial suspicion was tuberculous meningitis, considering the underlining abdominal TB, which was later supported by cerebrospinal fluid analysis showing lymphocytic-predominant pleocytosis and positive acid-fast bacilli staining. Concurrently, the patient developed hemodynamic instability and severe abdominal pain, which on repeat X-rays of the abdomen showed air under the diaphragms, prompting surgical exploration and revealing multiple ileal perforations. Histopathological examination confirmed TB as the cause of perforation. This case highlights the diagnostic and therapeutic complexities of concurrent tuberculous meningitis and intestinal TB perforation. Early recognition and interdisciplinary management are crucial for optimal patient outcomes.

Nano round polycrystalline adsorbent of chicken bones origin for Congo red dye adsorption.

Nano round polycrystalline adsorbent (NRPA) of chicken bones origin was utilize as effective adsorbent in Congo red dye removal via aqueous media. The NRPA adsorbent was prepared via thermal decomposition and its structure was investigated with the aids of Transmission Electron Microscopy, Fourier Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy, Energy Dispersive X-ray Analysis (EDX), and X-ray Diffractometer (XRD). A monophasic apatite phase was confirmed from XRD investigation, while functional groups analysis showed that NRPA possessed CO32-, PO43- and OH- absorption bands. The maximum adsorption capacities derived from Langmuir isotherm is 98.216 mg g-1. From the combined values of n from Freundlich and separation factor (RL) of Langmuir models, the adsorption of CR by NRPA is favourable. Thermodynamic values of 5.280 kJ mol-1 and 16.403 kJ mol-1 K-1 were found for ΔH° and ΔS° respectively. The entire values of ΔG° which ranges from - 35.248 to - 459.68 kJ mol-1 were all negative at different temperatures. Thus, nano polycrystalline adsorbent of chicken bone origin can serve as excellent adsorbent in Congo red dye removal from waste water.

Pyroptosis-related gene signature for predicting gastric cancer prognosis.

Gastric cancer (GC) is a prevalent form of malignancy characterized by significant heterogeneity. The development of a specific prediction model is of utmost importance to improve therapy alternatives. The presence of H. pylori can elicit pyroptosis, a notable carcinogenic process. Furthermore, the administration of chemotherapeutic drugs is often employed as a therapeutic approach to addressing this condition. In the present investigation, it was observed that there were variations in the production of 17 pyroptosis-regulating proteins between stomach tissue with tumor development and GC cells. The predictive relevance of each gene associated with pyroptosis was assessed using the cohort from the cancer genome atlas (TCGA). The least absolute shrinkage and selection operator (LASSO) was utilized to enhance the outcomes of the regression approach. Patients with gastric cancer GC in the cohort from the TCGA were categorized into low-risk or high-risk groups based on their gene expression profiles. Patients with a low risk of gastric cancer had a higher likelihood of survival compared to persons classified as high risk (P<0.0001). A subset of patients diagnosed with GC from a Genes Expression Omnibus (GEO) cohort was stratified according to their overall survival (OS) duration. The statistical analysis revealed a higher significance level (P=0.0063) regarding OS time among low-risk individuals. The study revealed that the GC risk score emerged as a significant independent prognostic factor for OS in patients diagnosed with GC. The results of Gene Ontology (GO) and Kyoto Encyclopaedia of Genes and Genomes (KEGG) research revealed that genes associated with a high-risk group had significantly elevated levels of immune system-related activity. Furthermore, it was found that the state of immunity was diminished within this particular group. The relationship between the immune response to cancer and pyroptosis genes is highly interconnected, suggesting that these genes have the potential to serve as prognostic indicators for GC.

The Expression of Mucin-4 (MUC4) in Sarcomas Apart From Sclerosing Epithelioid Fibrosarcoma and Low-Grade Fibromyxoid Sarcoma.

Background Low-grade fibromyxoid sarcoma (LGFMS) and sclerosing epithelioid fibrosarcoma (SEF) are two rare but aggressive soft tissue sarcomas that can be difficult to distinguish due to histopathological similarities. The present study examines the diagnostic capacities of mucin-4 (MUC4), a transmembrane mucin, in identifying different types of sarcomas and broadens its evaluation to include a wide range of sarcomas. Methods Immunohistochemical (IHC) examination of tissue samples from various sarcomas was performed using a mouse anti-MUC4 monoclonal antibody. IHC was conducted on 4-mm thick formalin-fixed paraffin-embedded tissue sections after pressure cooker antigen retrieval with a mouse anti-MUC4 monoclonal antibody. Results MUC4 was shown to be highly expressed in SEF (n=13) and LGFMS (n=10), while focal positivity in synovial sarcoma (n=1). Other sarcomas, such as malignant peripheral nerve sheath tumors, fibrosarcoma, leiomyosarcoma, liposarcoma, and myxofibrosarcoma, exhibited no expression (n=0). These findings are consistent with previous research and support MUC4 specificity as a SEF and LGFMS marker. This study provides information on the diagnostic efficacy of MUC4, particularly in the context of certain subtypes. It not only helps our understanding of these unique instances, but it also provides context for histopathological and IHC findings in soft tissue sarcoma. Furthermore, this study investigates the influence of age and gender on MUC4 expression in a range of sarcomas, which was typically understudied in the literature and found no relation with expression of MUC4. Conclusion In conclusion, this study adds to our understanding of soft tissue sarcomas by emphasizing the crucial role of MUC4 in certain sarcoma subtypes while acknowledging the complex variety of the sarcoma landscape. Further research is needed to understand the molecular mechanism that governs marker expression patterns, as well as the therapeutic implications.

Acute Tubulointerstitial Nephritis and Secondary Renal Amyloidosis: A Rare Complication of Atezolizumab.

Lung cancer is the second most common malignancy in both genders and the most common cause of cancer-related deaths worldwide. Broadly, lung cancer is divided into two types: small-cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). Non-small cell lung cancer accounts for 85% of the diagnoses of lung cancer. It is necessary to check for any targetable mutations, which can help in deciding the treatment plan for the patients. The patient we are reporting is a 70-year-old male with multiple co-morbidities diagnosed with non-small cell carcinoma, favoring adenocarcinoma on histopathology. He was started on Atezolizumab/Bevacizumab/Carboplatin/Paclitaxel (ABCP). He was switched to maintenance Atezolizumab/Bevacizumab after four cycles due to poor tolerance to carboplatin and paclitaxel. The patient presented with neutropenic colitis and acute kidney injury (AKI), requiring admission. workup revealed nephrotic range proteinuria with a high urinary albumin-to-creatinine ratio. He underwent a renal biopsy to ascertain the cause of his proteinuria, which showed marked acute and chronic tubulo-interstitial nephritis (TIN), amyloidosis, and global glomerulosclerosis. Secondary (AA) amyloidosis is characterized by the extracellular deposition of misfolded proteins. Although interstitial nephritis is a reported side effect of immune checkpoint inhibitors, AA amyloidosis is a rarer side effect. So, to determine the exact cause and early therapeutic intervention in immune checkpoint inhibitor-related kidney injury, large retrospective or prospective studies should be done.

The syntax of wh-questions in unaccusative and (Un)ergative structures in Mehri language: A Phase-based approach.

The Mehri Language is an endangered language spoken in eastern Yemen, a sub-group of the Semitic language family, and a Southern Arabic language. The syntax of Mehri wh-questions has not been explored within minimalism; hence, there is a morpho-syntactic need to provide a modern analysis of wh-questions in order to show how the interrogative structures can be derived. This study aims to examine the syntax of the wh-question movement in Mehri's unaccusative/ergative and unergative structures and answer the following questions within Chomsky's (2000 and 2008) Phase-based Theory: (i) Does the Mehri language allow fronting of wh-phrases to [Spec-CP]? And (ii) how can wh-movement in Mehri unaccusative and (un)ergative structures be accounted for? This work presents a novel analysis of wh-question movement in unaccusative/ergative and unergative structures in Mehri; it demonstrates that the source head C triggers the movement of wh-adjunct and wh-subject phrases. In wh-adjunct extraction, two strategies are employed: overt wh-fronting and wh-in-situ; when the head Foc inherits an edge feature from C, wh-adjunct overtly undergoes movement from its original position within v*P to the left peripheries of [Spec-FocP] and subsequently to [Spec-CP]. When the lexical wh-adjunct remains within v*P, its question features covertly move to [Spec-CP], because the head Foc does not inherit an edge feature from C. In wh-subject extraction, the wh-subject overly undergoes movement to [Spec-CP] because C obligatorily inherits the edge feature to the head Top, which triggers movement of the illogical subject in unaccusative/ergative structures and the logical external specifier in unergative structures to [Spec-CP]. Moreover, Mehri obeys the Phase Impenetrability Condition of Chomsky, where wh-subject and wh-adjunct phrases must pass through certain phases until [Spec-CP].

Poncet's disease: An uncommon presentation of a common disease in Sudan.

Key Clinical Message: Poncet's disease is an acute onset reactive polyarthritis associated with tuberculosis infection. Although uncommon, the diagnosis should be considered among patients presenting with symmetrical polyarthritis in tuberculosis-endemic regions. Abstract: This is a case report of Poncet's disease presenting as bilateral knee and wrist pain associated with swelling. Joint x-rays and immunological assays were normal. A chest x-ray and Gene-Xpert diagnosed tuberculosis. A complete resolution of symptoms was attained following the completion of antituberculous therapy regimen.

Rates of the Trans-radial Approach in Elective and Emergency Coronary Angiography in Iraq: A Cross-Sectional Study.

Background and aims The trans-radial access is becoming the default approach in many cardiac centers worldwide. Data from the Middle East, including Iraq, on the trends and rates of the use of trans-radial access are scarce. The aim of this study is to determine the rates of trans-radial approach (TRA) versus transfemoral approach (TFA) in patients with coronary artery syndromes undergoing coronary angiography and/or percutaneous coronary intervention (PCI) in Iraq. Methods In this multicenter prospective study, we collected 885 cases of coronary artery disease undergoing coronary angiography/PCI from three main cities of the Kurdistan Region in Iraq from 2022 to 2023. Results Of the total sample, 57.2% were diagnostic coronary angiography and 42.8% were PCI, 57.1% of all cases were TFA and 42.9% were TRA, and 64.3% of PCI cases were performed through TFA. Eghty-two percent of total emergency PCI included (primary PCI) cases underwent the procedure through the TFA, and only 18% of such cases were through the TRA. The overall crossover rate between both approaches happened in 14 (3.6%) cases. Conclusions Despite its main benefits, the radial access use in the Cath lab is yet underused in our region. Further steps in training programs are indicated to popularize the use of radial access among interventional cardiologists in addition to transfemoral access.

Relapse of Non-Gastrointestinal Langerhans Cell Histiocytosis in the Rectum in a Child: A Case Report.

Langerhans cell histiocytosis (LCH) is a rare disorder most commonly involving skin, bone and lung. The gastrointestinal tract (GIT) is an uncommon site of disease and only a handful of case reports exist. We present a case of a 15-year old boy with treated LCH involving the skin, bones, central nervous system (CNS) and pituitary gland. He presented with rectal bleeding and on investigation was found to have a single rectal polyp which was confirmed histologically and immunologically to be LCH. Further investigation revealed no other foci of disease.

Expression of NKX2.2 in Non-Ewing Tumors With Round Cell Morphology.

Background Round cell sarcomas pose diagnostic challenges due to overlapping histopathological features, necessitating precise immunohistochemical markers for accurate categorization. NKX2.2 has emerged as a sensitive diagnostic tool, particularly in Ewing sarcoma. This study extends this understanding to various round-cell sarcomas, shedding light on the potential diagnostic utility of NKX2.2 beyond its established role. The nuanced exploration of NKX2.2 expression aims to enhance diagnostic strategies, prognostic assessments, and therapeutic developments in the landscape of sarcoma research. Methodology Cases were retrieved from the surgical pathology and consultation files of Shaukat Khanum Memorial Cancer Hospital and Research Center, Lahore, Pakistan. Representative hematoxylin and eosin-stained slides of six different types of already confirmed tumors, including lymphoblastic lymphoma, neuroblastoma, rhabdomyosarcoma, synovial sarcoma, Wilms tumor, and Ewing sarcoma, were reviewed by a panel of pathologists. Immunohistochemistry, utilizing a rabbit anti-NKX2.2 monoclonal antibody, was performed on formalin-fixed paraffin-embedded tissue sections. The presence of NKX2.2 was defined as moderate or high nuclear immunoreactivity in at least 5% of cells. Results The histopathological examination revealed characteristic features in each sarcoma subtype, aligning with established diagnostic criteria. In Lymphoblastic lymphoma, T-cell lineage was confirmed through TdT expression, while the atypical finding of focal NKX 2.2 expression hinted at genetic diversity. Neuroblastoma exhibited the expected salt and pepper chromatin pattern, with NKX 2.2 expression raising questions about its prognostic significance. Rhabdomyosarcoma presented primitive cells expressing desmin, and NKX 2.2 focal expression echoed previous subtype-associated studies. Synovial sarcoma displayed both monophasic and biphasic growth patterns and TLE1 expression, with NKX 2.2 variation suggesting tumor heterogeneity. In Wilms tumor, the characteristic WT1 expression was observed, while NKX2.2's absence reaffirmed its irrelevance in this context. Ewing sarcoma displayed the anticipated homogenous cell population, strong NKX2.2 expression, and CD99 positivity across various sites. Furthermore, age and gender impact on this range of sarcomas found no significant relation with an expression of NKX2.2. Conclusion In conclusion, the diverse expression profiles of diagnostic markers discovered in this study, particularly the atypical expression of NKX2.2 beyond its established role in Ewing sarcoma, signify a significant advancement. This unique finding accentuates the potential diagnostic importance of NKX2.2 in various sarcomas, presenting a novel dimension to our understanding of these malignancies.

Epilepsia Partialis continua secondary to diabetic ketoacidosis.

Epilepsia partialis continua is a rare epileptic syndrome presenting with simple, partial, repetitive motor seizures. It can be a result of structural central nervous system lesion or due to metabolic causes. We report a case of a 65-year-old male patient diagnosed with EPC secondary to diabetic ketoacidosis.

Novel electrospun polyurethane grafts for vascular access in rats.

OBJECTIVES: The purpose of this study is to develop a new and improved polyurethane (PU) graft using electrospinning and chemical modifications for hemodialysis patients, which will replace the current standard, polytetrafluoroethylene (PTFE) graft. The chemical modifications aim to improve hemocompatibility and reduce thrombogenicity and neointimal hyperplasia. METHOD: The study population was randomized and divided equally into four groups; one control group received a PTFE graft, and three treatment groups received three different types of polyurethane grafts. Two duplex measurements were performed directly on the graft on the same locations, followed by a histologic examination. RESULTS: In the first few days after the implantation animals lost some weight, it took a week to recover to pre-surgical weight. Throughout the 28 days, there was no significant difference between animals in wound, activity, and the general appearance. PTFE and PU A groups have lower compliance or reduced graft diameter due to neointimal hyperplasia development on Doppler interrogation. The histological analysis showed limited neointimal hyperplasia development and no excessive inflammatory response to any of the grafts. CONCLUSION: This study demonstrates that animals with polyurethane grafts show better blood flow because the developed NIH was inconspicuous, as indicated by the different velocity measure than controls on Duplex and minimal NIH development microscopically.

Metallic stent insertion to relieve malignant bowel obstruction in a child: a case report.

Self-expandable metallic stents (SEMS) have been widely used in adults to relieve obstruction secondary to colorectal tumours. However, there is a paucity of literature about their use in children, with only a few case reports describing stent insertion in children with benign colonic conditions. There is one case report on a malignant colonic condition in a child by Hussain et al. in the literature. However, due to the rarity of the condition, there are currently no guidelines from learned societies on colorectal SEMS placement in paediatric patients. We share our experience of using a fully covered SEMS to relieve malignant colonic obstruction in a 6 year-old-child, who was on treatment for T cell lymphoma. This was done as a bridge to surgery, thereby allowing planned surgery, and avoiding colostomy in this child, who went on to have colonic resection with primary anastomosis.

Automated Facial Expression Recognition Framework Using Deep Learning.

Facial expression is one of the most significant elements which can tell us about the mental state of any person. A human can convey approximately 55% of information nonverbally and the remaining almost 45% through verbal communication. Automatic facial expression recognition is presently one of the most difficult tasks in the computer science field. Applications of facial expression recognition (FER) are not just limited to understanding human behavior and monitoring person's mood and the mental state of humans. It is also penetrating into other fields such as criminology, holographic, smart healthcare systems, security systems, education, robotics, entertainment, and stress detection. Currently, facial expressions are playing an important role in medical sciences, particularly helping the patients with bipolar disease, whose mood changes very frequently. In this study, an algorithm, automated framework for facial detection using a convolutional neural network (FD-CNN) is proposed with four convolution layers and two hidden layers to improve accuracy. An extended Cohn-Kanade (CK+) dataset is used that includes facial images of different males and females with expressions such as anger, fear, disgust, contempt, neutral, happy, sad, and surprise. In this study, FD-CNN is performed in three major steps that include preprocessing, feature extraction, and classification. By using this proposed method, an accuracy of 94% is obtained in FER. In order to validate the proposed algorithm, K-fold cross-validation is performed. After validation, sensitivity and specificity are calculated which are 94.02% and 99.14%, respectively. Furthermore, the f1 score, recall, and precision are calculated to validate the quality of the model which is 84.07%, 78.22%, and 94.09%, respectively.

Acute Health Effects and Outcome Following Sarin Gas Attacks in Khan Shaykhun, Syria.

Background In 2017, Idlib, Syria, was exposed to a chemical attack with sarin gas. Many patients of the attack were presented to the Al Rahman Charity Hospital in northern Syria. The aim of this study is to describe the clinical manifestations of sarin gas exposure, as well as the management and outcome of these manifestations in areas with poor healthcare infrastructure. Methods In a case series study design, medical records of suspected sarin exposed patients were reviewed in terms of age, gender, initial clinical presentation, management, and outcome. Results Seventeen patients with signs of sarin gas exposure had detailed medical records. The mean age was 29.1 years with a range of 4-70 years. Six patients were male (35.3%), and four (23.5%) were children under 18 years. At initial presentation, all victims suffered from respiratory distress because of severe airway inflammation, chest pain, and ophthalmological symptoms. All patients featured varying degrees of intestinal, neurologic, and dermatological signs and symptoms. Acute symptom management consisted of oxygen (100% of patients), atropine (100%), bronchodilators (82.4%), dexamethasone (82.4%), anti-emetics (82.4%), paracetamol (47.1%), and ranitidine (41.2%). Rapid symptomatic recovery was observed in 13 patients (76.5%) who stayed in the hospital for less than 24 hours, but four patients (23.5%) had to be admitted for more than 24 hours. The median length of stay was 22.2 hours (with a range of eight to 48 hours). Two patients required intensive care. Of the studied sample, all patients survived. Interpretation This study demonstrates that even in austere healthcare settings, survival rate and prognosis of sarin gas contaminated patients are fair if basic measures and symptomatic treatment are performed. The study provides insight into the clinical presentation, management, and hospital course likely to result from future sarin gas releases.

Pyloric stent insertion in malignant gastric outlet obstruction: moving beyond palliation.

BACKGROUND: Self-expandable metallic stents have not only largely replaced surgical gastrojejunostomy for unresectable gastric cancers, but their role as bridging therapy for resectable obstructing tumours is also evolving. OBJECTIVE: To evaluate the efficacy and safety of pyloric stents in gastric outlet obstruction in patients with gastric cancer and assess survival in patients with resectable obstructing gastric tumours in whom stents were inserted as a bridge to surgery. METHODS: We retrospectively reviewed the electronic medical records of patients who underwent self-expandable metallic stent insertion for gastric outlet obstruction due to gastric cancer from January 2014 to March 2019. RESULTS: Out of 161 patients, clinical improvement was observed in 159 (99%) and 156 (97%) at 1 and 12 weeks of stent placement, respectively. None of these patients experienced serious complications, such as perforation or aspiration pneumonia. Of these 161 patients, enteral stents were placed as bridging therapy prior to surgery in 40 (24.8%). Among these, 35 (87.5%) of 40 underwent neo-adjuvant chemotherapy followed by curative surgery. Of the 35 patients, 3 failed to follow-up. One-year survival following curative surgery was 87.5%. Stent helped to reduce vomiting and improve nutrition, measured by the body mass index (p = 0.36) and serum albumin (p = 0.05), over a 4-week period following stent insertion. CONCLUSION: Pyloric stents are useful in relieving malignant gastric outlet obstruction, maintaining nutrition during neo-adjuvant treatment and improving survival without additional risk of postoperative complications. They have traditionally been used for palliation, but should also be considered as bridging therapy for obstructing resectable gastric tumours during neo-adjuvant treatment.

Effects of Two Chlorine Gas Attacks on Hospital Admission and Clinical Outcomes in Kafr Zita, Syria.

Background In 2014, Hama Governorate was exposed twice to chlorine gas, with 15 patients presenting to Kafr Zita Hospital in Northwest Syria. This study aimed to describe clinical manifestations of chlorine gas exposure to identify factors leading to facility admission and the need for ICU/intubation in conflict-affected areas with limited healthcare infrastructure. Methods We conducted a case-series study, using medical records of suspected chlorine-exposed patients presenting at Kafr Zita Hospital on either 11 April or 22 May 2014. Data on age, sex, initial clinical presentation, therapeutic management, and outcome were compared by hospital admission/non-admission and attack date. All patients provided verbal informed consent. Results Fifteen patients with signs of chlorine gas exposure had detailed medical records. The mean age was 25.7 years (range 2-59), eight were male (53%), and three (20%) were under age 16. At initial presentation, all experienced respiratory distress, due to severe airway inflammation confirmed by nonspecific pulmonary infiltrates on chest x-ray, and similar intestinal, neurological, dermatological, ophthalmological, and psychological signs and symptoms. Acute management consisted of oxygen and bronchodilators for all patients, hydrocortisone (93%), antiemetics (80%), and dexamethasone (13%). Seven (47%) made a rapid symptomatic recovery and were discharged the same day and eight (53%) were admitted for a median of two days (range 1-6 days), one of whom required intubation and later died. The only significant associations found were higher mean pulse rate (i.e. 138 versus 124; p=0.043) and body temperature (37.0 versus 36.5; p=0.019) among admitted patients compared to non-admitted. Conclusion Our results demonstrated that even in low-resource humanitarian settings the survival rate for chlorine gas exposed patients is fair. Despite the small sample, this study provides insight into the clinical presentation, management, and outcomes of weaponized chlorine gas exposure, though further research is required to understand any chronic consequences.

Arteriovenous Malformations in Proximal Part of Ileum: A Case Report.

Arteriovenous malformations in the ileum are a rare cause of gastrointestinal bleeding in young adults with few reported cases and pose difficulty in diagnosing. They usually present with chronic gastrointestinal bleed. A 30-year-old woman presented with an acute episode of hematochezia with a history of intermittent melena for 1.5 years. Complete blood count revealed a low hemoglobin level of 3.5g/dl and hypochromic microcytic anemia. Oesophago-gastro-duodenoscopy was normal; however, a colonoscopy revealed the terminal ileum and colon filled with blood. Computed tomography-Angiogram showed local intraluminal contrast extravasation in the ileum. Explorative laparotomy and on-table enteroscopy were performed identifying a small elevated, pigmented, and eroded mucosa (5 to 6 mm) in proximal ileum; resection and primary anastomosis were performed. The patient was followed after surgical resection and her symptoms improved dramatically with no additional episodes of melena and with the normalization of hemoglobin.

Demographic, clinical and angiographic profile of coronary artery disease in kurdistan region of Iraq.

INTRODUCTION: The characters of coronary artery disease with its risk factors and coronary angiograms studied elsewhere revealed differences in different populations. We, here, assess the regional characters of coronary artery disease with its major risk factors and coronary angiographic profile in Duhok, Kurdistan region of Iraq. METHODS: We conducted this cross sectional study at the Azadi heart center in Duhok, Iraq. A consecutive sampling procedure was used to enroll a total of 300 adult patients with coronary artery disease (145 men and 155 women) who had undergone coronary angiography. Direct interview was used with designed questionnaire to collect demographic, cardiovascular risk factors and angiographic profiles. RESULTS: The mean patient's age was 55.5 (10.4) years. The most prevalent risk factor was hypertension (55.3%), followed by dyslipidemia (42.7%), type 2 diabetes mellitus (29%), smoking (11%) and ex-smoking (9.3%). Apart from smoking all other risk factors were more frequent in women. Angiographic analysis revealed normal angiograms in (29.3%) versus single vessel disease (23.3%), double vessel disease (14.3%), triple vessel disease (21.3%) and non significant (11.7%). As to the coronary branch involved, the most frequently affected was the left anterior descending artery followed by right coronary artery, left circumflex artery, and left main stem (60.7%, 46.3%, 43.7% and 6% respectively). CONCLUSION: This study showed that the coronary artery disease tends to occur earlier in our population. Although cardiovascular risk factors were clustered among women, older men showed more aggressive coronary angiographic lesions.
