Misoprostol and mid trimester termination of pregnancy in patients with two previous scars and more at Elwiya Maternity Teaching Hospital / Misoprostol e interrupção da gravidez no meio do trimestre em pacientes com duas cicatrizes anteriores e mais no Elwiya Maternity Teaching Hospital

Abstract Objectives: to determine efficiency and safety of three misoprostol regimens for 2nd trimester pregnancy termination in individuals with two or more cesarean section scars. Methods: a cross-sectional study included 100 pregnant ladies at 13th-26th weeks gestation with previous two cesarean sections (CSs) who were scheduled for pregnancy termination using misoprostol. Patients were conveniently assigned to 100µg/3h, 200µg/3h or 400 µg/3h regimens. Primary outcome was time to abortion, secondary outcomes were side effect and complications. Results: a significant association was found between number previous CSs and longer time to abortion (p=0.01). A highly significant association was identified between earlier gestational age and longer time to abortion (p<0.001). Lower side effects and complications were associated with 200 µg misoprostol every 3 hours of (p<0.001). Incomplete abortion was the most frequent recorded complication for the successive doses of misoprostol. Conclusions: misoprostol is an effective drug at low doses for pregnancy termination in women with prior two or more caesarean sections. However, its safety needs monitoring of the patient in the hospital to decrease morbidity and mortality behind its use.

Resumo Objetivos: determinar a eficiência e segurança de três regimes de misoprostol para interrupção da gravidez no segundo trimestre em indivíduos com duas ou mais cicatrizes de cesariana. Métodos: um estudo transversal incluiu 100 gestantes entre 13ª e 26ª semanas de gestação com duas cesarianas (CEs) anteriores que foram agendadas para interrupção da gravidez com uso de misoprostol. Os pacientes foram convenientemente designados para regimes de 100 µg/3 horas, 200 µg/3 horas ou 400 µg/3 horas. O desfecho primário foi o tempo para o aborto, os desfechos secundários foram efeitos colaterais e complicações. Resultados: foi encontrada associação significativa entre o número de cesáreas anteriores e o maior tempo até o aborto (p=0,01). Foi identificada associação altamente significativa entre idade gestacional mais precoce e maior tempo para abortar (p<0,001). Menores efeitos colaterais e complicações foram associados com 200 µg de misoprostol a cada 3 horas (p<0,001). O aborto incompleto foi a complicação mais frequente registrada para as doses sucessivas de misoprostol. Conclusões: o misoprostol é um medicamento eficaz em doses baixas para interrupção da gravidez em mulheres com duas ou mais cesarianas anteriores. Porém, sua segurança necessita de monitoramento do paciente no hospital para diminuir a morbimortalidade por trás de seu uso.

Visualization of nasal powder distribution using biomimetic human nasal cavity model

Nasal drug delivery efficiency is highly dependent on the position in which the drug is deposited in the nasal cavity. However, no reliable method is currently available to assess its impact on delivery performance. In this study, a biomimetic nasal model based on three-dimensional (3D) reconstruction and three-dimensional printing (3DP) technology was developed for visualizing the deposition of drug powders in the nasal cavity. The results showed significant differences in cavity area and volume and powder distribution in the anterior part of the biomimetic nasal model of Chinese males and females. The nasal cavity model was modified with dimethicone and validated to be suitable for the deposition test. The experimental device produced the most satisfactory results with five spray times. Furthermore, particle sizes and spray angles were found to significantly affect the experimental device's performance and alter drug distribution, respectively. Additionally, mometasone furoate (MF) nasal spray (NS) distribution patterns were investigated in a goat nasal cavity model and three male goat noses, confirming the in vitro and in vivo correlation. In conclusion, the developed human nasal structure biomimetic device has the potential to be a valuable tool for assessing nasal drug delivery system deposition and distribution.

Deep learning-based radiomics allows for a more accurate assessment of sarcopenia as a prognostic factor in hepatocellular carcinoma / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Hepatocellular carcinoma (HCC) is one of the most common malignancies and is a major cause of cancer-related mortalities worldwide (Forner et al., 2018; He et al., 2023). Sarcopenia is a syndrome characterized by an accelerated loss of skeletal muscle (SM) mass that may be age-related or the result of malnutrition in cancer patients (Cruz-Jentoft and Sayer, 2019). Preoperative sarcopenia in HCC patients treated with hepatectomy or liver transplantation is an independent risk factor for poor survival (Voron et al., 2015; van Vugt et al., 2016). Previous studies have used various criteria to define sarcopenia, including muscle area and density. However, the lack of standardized diagnostic methods for sarcopenia limits their clinical use. In 2018, the European Working Group on Sarcopenia in Older People (EWGSOP) renewed a consensus on the definition of sarcopenia: low muscle strength, loss of muscle quantity, and poor physical performance (Cruz-Jentoft et al., 2019). Radiological imaging-based measurement of muscle quantity or mass is most commonly used to evaluate the degree of sarcopenia. The gold standard is to measure the SM and/or psoas muscle (PM) area using abdominal computed tomography (CT) at the third lumbar vertebra (L3), as it is linearly correlated to whole-body SM mass (van Vugt et al., 2016). According to a "North American Expert Opinion Statement on Sarcopenia," SM index (SMI) is the preferred measure of sarcopenia (Carey et al., 2019). The variability between morphometric muscle indexes revealed that they have different clinical relevance and are generally not applicable to broader populations (Esser et al., 2019).

Up-regulation of GINS1 highlighted a good diagnostic and prognostic potential of survival in three different subtypes of human cancer

Abstract Cancer is a fatal malignancy and its increasing worldwide prevalence demands the discovery of more sensitive and reliable molecular biomarkers. To investigate the GINS1 expression level and its prognostic value in distinct human cancers using a series of multi-layered in silico approach may help to establish it as a potential shared diagnostic and prognostic biomarker of different cancer subtypes. The GINS1 mRNA, protein expression, and promoter methylation were analyzed using UALCAN and Human Protein Atlas (HPA), while mRNA expression was further validated via GENT2. The potential prognostic values of GINS1 were evaluated through KM plotter. Then, cBioPortal was utilized to examine the GINS1-related genetic mutations and copy number variations (CNVs), while pathway enrichment analysis was performed using DAVID. Moreover, a correlational analysis between GINS1 expression and CD8+ T immune cells and a the construction of gene-drug interaction network was performed using TIMER, CDT, and Cytoscape. The GINS1 was found down-regulated in a single subtypes of human cancer while commonly up-regulated in 23 different other subtypes. The up-regulation of GINS1 was significantly correlated with the poor overall survival (OS) of Liver Hepatocellular Carcinoma (LIHC), Lung Adenocarcinoma (LUAD), and Kidney renal clear cell carcinoma (KIRC). The GINS1 was also found up-regulated in LIHC, LUAD, and KIRC patients of different clinicopathological features. Pathways enrichment analysis revealed the involvement of GINS1 in two diverse pathways, while few interesting correlations were also documented between GINS1 expression and its promoter methylation level, CD8+ T immune cells level, and CNVs. Moreover, we also predicted few drugs that could be used in the treatment of LIHC, LUAD, and KIRC by regulating the GINS1 expression. The expression profiling of GINS1 in the current study has suggested it a novel shared diagnostic and prognostic biomarker of LIHC, LUAD, and KIRC.

Resumo O câncer é uma doença maligna fatal e sua crescente prevalência mundial exige a descoberta de biomarcadores moleculares mais sensíveis e confiáveis. Investigar o nível de expressão de GINS1 e seu valor prognóstico em cânceres humanos distintos, usando uma série de abordagens in silico em várias camadas, pode ajudar a estabelecê-lo como um potencial biomarcador de diagnóstico e prognóstico compartilhado de diferentes subtipos de câncer. O mRNA de GINS1, a expressão da proteína e a metilação do promotor foram analisados usando UALCAN e Human Protein Atlas (HPA), enquanto a expressão de mRNA foi posteriormente validada via GENT2. Os valores prognósticos potenciais de GINS1 foram avaliados por meio do plotter KM. Em seguida, o cBioPortal foi utilizado para examinar as mutações genéticas relacionadas ao GINS1 e as variações do número de cópias (CNVs), enquanto a análise de enriquecimento da via foi realizada usando DAVID. Além disso, uma análise correlacional entre a expressão de GINS1 e células imunes T CD8 + e a construção de uma rede de interação gene-droga foi realizada usando TIMER, CDT e Cytoscape. O GINS1 foi encontrado regulado negativamente em um único subtipo de câncer humano, enquanto comumente regulado positivamente em 23 outros subtipos diferentes. A regulação positiva de GINS1 foi significativamente correlacionada com a sobrevida global pobre (OS) de Carcinoma Hepatocelular de Fígado (LIHC), Adenocarcinoma de Pulmão (LUAD) e Carcinoma de Células Claras Renais de Rim (KIRC). O GINS1 também foi encontrado regulado positivamente em pacientes LIHC, LUAD e KIRC de diferentes características clínico-patológicas. A análise de enriquecimento de vias revelou o envolvimento de GINS1 em duas vias diversas, enquanto poucas correlações interessantes também foram documentadas entre a expressão de GINS1 e seu nível de metilação do promotor, nível de células imunes T CD8 + e CNVs. Além disso, também previmos poucos medicamentos que poderiam ser usados no tratamento de LIHC, LUAD e KIRC, regulando a expressão de GINS1. O perfil de expressão de GINS1 no estudo atual sugeriu que é um novo biomarcador de diagnóstico e prognóstico compartilhado de LIHC, LUAD e KIRC.

BACKGROUND: COVID-19 patients may experience Long-lasting symptoms from weeks to even months. AIM: To evaluate long-term cognitive impairment based on the severity of symptoms of COVID-19 infection in a primary health system setting. Material and Methods: From a database of 363 patients, 83 cases aged 47 ± 15 years, (58% females) were selected from June to August 2020. In patients who survived the virus, 24 infection-related symptoms were collected to create three severity clusters (mild, moderate, and severe). The follow-up time was at least seven months. Comparing the first two clusters with the severe cluster, the existence of brain fog and risk factors (obesity, hypertension, diabetes, chronic lung disease, and hypothyroidism) were analyzed. RESULTS: Thirty-one patients (37%) had persistent symptoms lasting up to 240 days. Fifty-one patients (61%) experienced brain fog. Concentration was affected by symptom severity (odds ratio [OR] 3.63, 95% confidence interval [CI] 1.26-10.46, p = 0.02). Short- or long-term memory loss was not affected. Moreover, symptom severity was related to brain fog (OR 3.16, 95% CI 1.05-9.51, p = 0.04). Patients with persistent symptoms had a concentration impairment associated with severity patterns (OR 24.3, 95% CI 1.73-340.11, p = 0.03). Conclusions: Brain fog is associated with symptom severity in COVID-19 survivors and lasts for more than eight months.

Los portadores de síntomas prolongados tuvieron una alteración de la concentración asociado a severidad (RR: 3,16, IC95%: 1,05-9,51, p= 0,04). Conclusiones: La niebla cerebral está relacionada con la severidad de los síntomas en supervivientes de COVID-19 permaneciendo por más de ocho meses.

Correlation of Clinical Profile and Electroencephalographic Finding in Hypoxic-Ischemic Encephalopathy in a Tertiary Care Hospital: A Single-Center Experience from Bangladesh

Background: Perinatal asphyxia and resultant hypoxic-ischemic encephalopathy (HIE) is not an uncommon phenomenon in a developing country, like Bangladesh. Electroencephalogram (EEG) is regarded as an effective prognostic tool. Correlation of clinical profiles and EEG findings of HIE patients arenot commonly observed in Bangladesh. The aim of the study was to observe the clinical profile and EEG changes in different stages of hypoxic-ischemic encephalopathy and compare them in a tertiary care hospital.Material & Methods:This is a cross-sectional observational study conducted for a period of six months in Dhaka Medical College Hospital, Dhaka. Sarnat and Sarnat score was used to classify HIE. 20 asphyxiated neonates without HIE were selected as the control group (group II) while 30asphyxiated neonates with HIE, were selected as the case group (group I) by purposive sampling. Clinical profiles, EEG findings, and immediate outcomes were observed and compared between the two groups.Results:73.3% patients were delivered at term and 30% patients were delivered at home in group I. 70% patients’ delivery were conducted by doctor in group I and 75% in group II. 63.3% patients had meconium stain in group I and 25% in group II, which was found significant. 46.7% had prolong labor in group I and 20% in group II, 40% had premature ruptured membrane (PROM) in group I and 40% in group II. Hypothermia, weak primitive reflexes, hypotonia, lethargy and seizure were significantly higher in group I. Changes in EEG correlated between the two groups and was found significant. Also, patients in group I, needed prolong hospital stay.Conclusions:The clinical profiles and EEG changes in patients with hypoxic ischemic encephalopathy was concluded that there is significant association with meconium stain, seizure, hypothermia, weak primitive reflexes, lethargic, miosis, hypotonia, poor APGAR score, burst suppression & SET findings in EEG and prolonged hospital stay in prenatal asphyxia with hypoxic ischemic encephalopathy.

Incidence of Olfactory and Gustatory Dysfunctions in the Early Stages of COVID-19: An Objective Evaluation

Abstract Introduction Coronavirus disease 2019 (COVID-19) is a dangerous infectious disease caused by a newly discovered severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has various clinical presentations. Numerable cases with non-specific olfactory and gustatory dysfunctions in COVID-19 have been reported from all over the globe. This is important as awareness will let people to self-isolate and help in limiting disease spread. Objective To objectively evaluate the frequency of olfactory and gustatory dysfunction, which may occur independently or with other symptoms, in laboratory confirmed COVID-19 patients at an early stage of the disease. Methods Objective evaluation of olfactory and gustatory function of 322 COVID-19 patients treated at our hospital, (SMGS, Government Medical College, Jammu), from August 2020 until November 2020. Results Our study population included 127 (39.4%) males and 195 (60.6%) females. Two hundred and twenty-six (70.2%) COVID-19 patients experienced olfactory and gustatory disorders. One hundred and sixty-five (51.2%) cases experienced both olfactory and gustatory disorders. Isolated olfactory dysfunction was reported in 34 (10.6%) patients, while 27 (8.4%) patients experienced only gustatory dysfunction. Conclusion The olfactory and gustatory dysfunctions, without any nasal obstruction or rhinorrhea, are significant symptoms in the clinical presentation of early COVID-19 patients. This presentation can be recognized at the earliest one, and it can reduce the high communicability of the COVID-19 disease.

Sequencing and mutations analysis of the first recorded SARS-CoV-2 Omicron variant during the fourth wave of pandemic in Iraq

Abstract Despite vaccine development and vaccination programs underway around the globe, the coronavirus disease 2019 (COVID-19) pandemic has not been controlled as the SARS-CoV-2 virus is evolving and new variants are emerging. This study was conducted to sequence and molecularly characterize the representing samples from the early fourth SARS-CoV-2 wave in Iraq. Here, we have performed next-generation sequencing of whole-genome sequencing of two representing samples from the country's early beginning of the fourth pandemic wave. The samples were sequenced using Illumina Miseq system, and the reference sequences were retrieved from GISAID database. Phylogenetic analysis was performed through Mega software. This study provides an initial sequence analysis and molecular characterization of the first Omicron variant cases recorded in the country. Our analysis revealed many mutations on the spike glycoprotein, especially on the receptor binding domain, with potential impact on immune escape and infectivity. The study findings suggest considering the highly mutated immunogenic epitope of the Omicron variant as a reference for developing a new vaccine for combating the ongoing pandemic.

Computer-aided screening for potential inhibitory compounds against a Klebsiella pneumoniae local isolate containing SHV-1 and CTX-M antibiotic resistance genes

Background@#Extended-spectrum beta-lactamases (ESBLs), which allow bacteria to become resistant to commonly used antibiotics against common pathogens such as Klebsiella pneumoniae, are a significant public health concern as their presence severely limits treatment options. Discovery and development of new drug entities are critical to effectively combat infections with these increasingly common antibiotic-resistant variants. @*Objective@#Computational approaches can accelerate and reduce the cost of the discovery phase by screening for inhibitors of “druggable” pathogen enzyme targets in silico. In this study, protein structures of the ESBL enzymes SHV-1 and CTX-M-15 were used as targets in molecular docking experiments to identify potential inhibitors for K. pneumoniae. @*Methodology@#5000 compounds from the Enamine Real HTS compound database were screened in silico for binding to SHV-1 and CTX-M-15. Twenty-six (26) compounds that were identified to have more favorable interactions compared to Avibactam, a known inhibitor of the target proteins, were tested for cytotoxic activities in vivo using Resazurin Microtiter Assay (REMA) against a K. pneumoniae clinical isolate containing both SHV-1 and CTX-M-15 resistance genes. @*Results and Conclusion@#Despite favorable binding energies in in silico screening, most of the compounds exhibited negligible inhibition on the growth of the K. pneumoniae clinical isolate in in vitro assays. This may be attributed to the fact that a phenotypic whole-cell assay, instead of an enzyme-targeted assay, was used for validation. Cell permeability requires a different set of molecular parameters which were not part of the study. Doxorubicin exhibited the highest in vitro bactericidal activity against this strain, which agrees with its known activity against many other bacterial pathogens and may be a promising compound for further lead optimization.

Effect and molecular mechanism research of Astragalus membranaceus on inhibiting intestinal absorption of six alkaloids of Aconitum carmichaelii in spleen deficiency rats / 中草药·英文版

Objective: To investigate the effect and the mechanism of Astragalus membranaceus (Huangqi in Chinese, HQ) extract on the intestinal absorption of six alkaloids of Aconitum carmichaelii (Fuzi in Chinese, FZ) in rats with spleen deficiency and provide novel insights into the application of HQ on modulating intestinal barrier. Methods: Four-week-old male Sprague-Dawley rats were fed with Xiaochengqi Decoction to induce the spleen deficiency model for 40 d. Single-pass intestinal perfusion model were used to study the effects of HQ extract on the absorption of alkaloids. Protein expression and mRNA levels of MRP2 and BCRP and tight junction proteins (TJ, including Claudin-1, Occludin and ZO-1) were measured using Western blot and real-time PCR, respectively. The location and expression of TJ protein was also investigated by the immunofluorescence method. Results: Compared with the normal group, the protein expression of MRP2, BCRP and TJ proteins in the model group were significantly down-regulated. After oral administration of HQ, the alkaloid absorption in intestinal villi was inhibited, MRP2, BCRP and TJ proteins were up-regulated, the green fluorescence staining of Claudin-1, Occludin, and ZO-1 was enhanced, and a thick layer of mucus was deposited on the surface of the epithelium of the intestinal cavity. Conclusion: HQ as an intestinal barrier modulator improves the physiological changes of the intestinal environment of spleen deficiency to reduce the absorption of toxic components, leading to a decrease in the absorption of drug-like molecules.

Abstract In modern agriculture the use of biostimulants not only reduces the cost of production but also increase yield and quality of crops without harming environment. The response of fodder oat to biostimulants was evaluated in a pot experiment using four biostimulants at different concentrations i.e Moringa leaf extract at ratio of 1:10, 1:20, 1:30, 1:40, 1:50, Sea weed extract at 1%, 2%, 3%, 4%, 5%, Thiourea at 100 ppm, 200 ppm, 300 ppm, 400 ppm, 500 ppm and Chitosan at 25 ppm, 50 ppm, 100 ppm, 125 ppm, 150 ppm. Oat crop was treated with biostimulants using foliar application, at two growth stages i.e tillering and booting. Data on various agronomic and quality parameters were recorded and analyzed. Results showed that biostimulants significantly affected phenology and quality of oat. The highest green fodder yield (872.32 g) was observed in the pots treated with 2%Solution of seaweed extract similarly highest dry matter yield was also highest at 170.85 g Interestingly crude protein was highest for thiourea at 400 ppm. In each biostimulant following doses stood out both in terms of yield and quality. In case of moringa leaf extract the ratio of 1:40with 900 g per pot yield and 9.43 % protein, for sea weed extract 2% was better than other doses with 981 g yield and 9.17% protein, for thiourea the 400 ppm was better than other concentrations as it shows highest yield (872.32 g) and crude protein (9.52%) and for chitosan 100 ppm was comparatively better in performance with 964.98 g yield per pot and 9.35% CP. It is concluded from our study that biostimulants improve fodder oat yield and quality.

Conversion to organic farming: a dynamic opportunity for Pakistani smallholders of fresh fruit / Conversão para a agricultura orgânica: uma oportunidade dinâmica para pequenos produtores de frutas frescas do Paquistão

ABSTRACT: Exporting the organic fresh fruit (FF) to Europe and America could be regarded as great opportunity for smallholders and suppliers of Gilgit Baltistan, Pakistan. Yet, the global organic farmland and the number of organic producers are continued to grow. To date, little is known about the behavior of Pakistani farmers towards organic fresh fruit production. This study examined the factors that influence the decision-making of fresh fruit smallholders concerning the conversion to organic farming (COF). This study uses Ajzen's theory of planned behavior (TPB) to predict the behavior of Pakistani smallholders of fresh fruit. Path analysis examined the utility of the extended version of the TPB model to anticipate 277 small-scale farmers' behavioral intentions towards the adoption of organic farming (AOF) and their prospect of converting their farm to organic produce within the next three years. The present study reported that the smallholders' attitude (ATT), subjective norms (SN), perceived behavior control (PBC), and farmer's group participation (FGP) were positively correlated with farmer's intention to adopt organic farming, while group participation of farmers has significant correlation with their behavior regarding production of organic fruits. The present study justifies using the model of farmers' group participation in policies that deliberately cheer up smallholders of fresh fruit to adopt organic farming, to raise farm incomes and to alleviate poverty.

RESUMO: Exportar a fruta fresca orgânica (FF) para a Europa e América pode ser considerada uma grande oportunidade para pequenos proprietários e fornecedores de Gilgit Baltistan, Paquistão. No entanto, as terras agrícolas orgânicas globais e o número de produtores orgânicos continuam a crescer. Até o momento, pouco se sabe sobre o comportamento dos agricultores paquistaneses em relação à produção de frutas frescas orgânicas. O objetivo deste estudo, portanto, foi examinar e determinar os fatores que influenciam a tomada de decisão dos pequenos produtores de frutas frescas sobre a conversão para a agricultura orgânica (COF). Este estudo usa a teoria do comportamento planejado de Ajzen (TPB) para prever o comportamento dos pequenos produtores de frutas frescas do Paquistão. A análise de caminho examinou a utilidade da versão estendida do modelo TPB para antecipar as intenções comportamentais de 277 agricultores de pequena escala em relação à adoção da agricultura orgânica (AOF) e sua perspectiva de converter sua fazenda em produtos orgânicos nos próximos três anos. O presente estudo descobriu que a atitude dos pequenos proprietários (ATT), as normas subjetivas (SN), o controle do comportamento percebido (PBC) e a participação do grupo de agricultores (FGP) foram positivamente correlacionadas com a intenção do agricultor de adotar a agricultura orgânica, enquanto a participação do grupo de agricultores correlação significativa com seu comportamento em relação à produção de frutas orgânicas. O presente estudo justifica o uso do modelo de participação de grupos de agricultores em políticas que encorajam deliberadamente os pequenos produtores de frutas frescas a adotar a agricultura orgânica, para aumentar a renda agrícola e diminuir a pobreza.

High-performance computing for SARS-CoV-2 RNAs clustering: a data science‒based genomics approach

Nowadays, Genomic data constitutes one of the fastest growing datasets in the world. As of 2025, it is supposed to become the fourth largest source of Big Data, and thus mandating adequate high-performance computing (HPC) platform for processing. With the latest unprecedented and unpredictable mutations in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the research community is in crucial need for ICT tools to process SARS-CoV-2 RNA data, e.g., by classifying it (i.e., clustering) and thus assisting in tracking virus mutations and predict future ones. In this paper, we are presenting an HPC-based SARS-CoV-2 RNAs clustering tool. We are adopting a data science approach, from data collection, through analysis, to visualization. In the analysis step, we present how our clustering approach leverages on HPC and the longest common subsequence (LCS) algorithm. The approach uses the Hadoop MapReduce programming paradigm and adapts the LCS algorithm in order to efficiently compute the length of the LCS for each pair of SARS-CoV-2 RNA sequences. The latter are extracted from the U.S. National Center for Biotechnology Information (NCBI) Virus repository. The computed LCS lengths are used to measure the dissimilarities between RNA sequences in order to work out existing clusters. In addition to that, we present a comparative study of the LCS algorithm performance based on variable workloads and different numbers of Hadoop worker nodes.

Solitary intratracheal neurofibroma: a rare tracheal tumor

Intratracheal neurofibromas are rare benign tumors with a tendency to transform into malignant form. Intratracheal neurofibroma remain asymptomatic and are incidentally found during routine radiography or may present with wheeze, cough and lower respiratory tract infection. We recently operated a 38 year old gentleman, who presented with progressive shortness of breath and chronic cough for two years. Examination was normal. CT identified a supracarinal, intratracheal mass. Rigid bronchoscopy revealed a hyper vascular mass, attached to membranous trachea. We performed resection anastomosis via right posterolateral thoracotomy. Histopathology revealed neurofibroma. Patient recovered well and was discharged after eight days.
