Elevation of the epidermal growth factor receptor and dependent signaling in human papillomavirus-infected laryngeal papillomas. (1/1167)
Laryngeal papillomas are benign tumors caused by human papillomaviruses types 6 and 11. This study addressed alterations in levels of signal transduction from the epidermal growth factor receptor (EGFR) in papillomas and cultured papilloma cells compared to normal tissue and cells. Mitogen-activated protein kinase (MAPK) was activated to a greater extent, phosphotyrosine was more abundant, and EGFR was overexpressed in laryngeal papillomas compared to normal laryngeal epithelium by Western blot analysis. The EGFR was 3 times more abundant in cultured papilloma cells than in normal laryngeal cells by Scatchard analysis and Western blot, without gene amplification or an increase in steady-state levels of mRNA. Following stimulation with EGF, a significant portion of the EGFR was recycled to the surface in papilloma cells, whereas in normal cells, it was not. Tyrosine kinase activity and activation of MAPK was more responsive to epidermal growth factor stimulation in papilloma cells than in uninfected primary laryngeal cells. PD153035, a specific inhibitor of the EGFR, and an EGFR-specific antibody that blocks ligand binding completely abrogated basal MAPK activation by endogenous ligands in laryngeal papilloma cells. These results demonstrated that infection of laryngeal epithelium by low-risk human papillomaviruses elevates the EGFR by posttranslational mechanisms, increasing its responsiveness to ligand-mediated activation. They also showed that MAPK activation in laryngeal papillomas depends upon ligand-mediated EGFR stimulation. (+info)Glutathione S-transferase GSTM3 and GSTP1 genotypes and larynx cancer risk. (2/1167)
Glutathione S-transferases (GSTs) are involved in detoxification of reactive metabolites of carcinogens and, therefore, could be potentially important in susceptibility to cancer. The associations between larynx cancer risk and GSTM3 and GSTP1 gene polymorphisms, either separately or in combination with GSTM1 and GSTT1 gene polymorphisms, were evaluated using peripheral blood DNA from 129 cancer patients and 172 controls, all regular smokers. The frequencies of GSTM3 AA, AB, and BB genotypes were 60.5%, 36.4%, and 3.1% in cases and 72.7%, 24.4%, and 2.9% in controls, respectively. The frequencies of GSTP1 AA, AG, and GG genotypes were 48.1%, 40.3%, and 11.6% in cases and 50.0%, 37.2%, and 12.8% in controls, respectively. Multivariate logistic regression analyses did not reveal any association between the GSTP1 (AG or GG) genotype and larynx cancer [odds ratio, 1.1; 95% confidence interval (CI), 0.7-2.0]. In contrast, a significant increase in risk was related to the GSTM3 (AB or BB) genotype (odds ratio, 2.0; 95% CI, 1.1-3.4). The combined GSTM3 (AB or BB) and GSTM1-null genotype conferred a 4-fold risk (95% CI, 1.6-10.1) of larynx cancer as compared with the combined GSTM3 AA and GSTM1-positive genotype. However, the effect of GSTM3 (AB or BB) genotype was similar among individuals with GSTM1-positive or GSTM1-null genotypes. (+info)Concordant induction of cyclin E and p21cip1 in differentiated keratinocytes by the human papillomavirus E7 protein inhibits cellular and viral DNA synthesis. (3/1167)
Productive infections by human papillomaviruses (HPVs) occur only in differentiated keratinocytes in squamous epithelia in which the HPV E7 protein reactivates the host DNA replication machinery to support viral DNA replication. In a fraction of the differentiated keratinocytes, E7 also posttranscriptionally induces p21Cip1, which is distributed in a mutually exclusive manner with unscheduled cellular DNA synthesis. In this study, double immunofluorescence labeling unexpectedly revealed that E7 caused a concordant accumulation of both cyclin E and p21Cip1 to high levels in patient papillomas and in organotypic cultures of primary human keratinocytes. The induction of cyclin E is mutually exclusive with unscheduled cellular DNA synthesis or abundant viral DNA. These novel virus-host interactions in differentiated keratinocytes are in contrast to previous observations made in submerged proliferating cultures, in which HPV E7 induces cyclin E and overcomes p21Cip1 inhibition of S-phase entry. We propose that an appropriately timed induction of cyclin E/cyclin-dependent kinase 2 by HPV E7 in postmitotic cells enables S-phase reentry and HPV DNA amplification, whereas prematurely induced cyclin E stabilizes p21Cip1 protein, which then inhibits cyclin E/cyclin-dependent kinase 2. Consequently, cyclin E and p21Cip1 both fail to turn over, and DNA synthesis does not occur. (+info)Preradiotherapy computed tomography as a predictor of local control in supraglottic carcinoma. (4/1167)
PURPOSE: To determine the utility of pretreatment computed tomography (CT) for predicting primary site control in patients with supraglottic squamous cell carcinoma (SCC) treated with definitive radiotherapy (RT). MATERIALS AND METHODS: Pretreatment CT studies in 63 patients were reviewed. Minimum length of follow-up was 2 years. Local recurrence and treatment complications resulting in permanent loss of laryngeal function were documented. Tumor volume was calculated using a computer digitizer, and pre-epiglottic space (PES) spread was estimated. The data were analyzed using a combination of Fisher's exact test, logistic regression modeling, and multivariate analyses. Five-year local control rates were calculated using the product-limit method. RESULTS: Local control rates were inversely and roughly linearly related to tumor volume, although there seemed to be a threshold volume at which primary site prognosis diminished. Local control was 89% in tumors less than 6 cm3 and 52% when volumes were > or =6 cm3 (P = .0012). The likelihood of maintaining laryngeal function also varied with tumor volume: 89% for tumors less than 6 cm3 and 40% for tumors > or =6 cm3 (P = .00004). Pre-epiglottic space involvement by tumor of > or =25% was associated with a reduced chance of saving the larynx (P = .0076). Multivariate analyses revealed that only tumor volume independently altered these end points. CONCLUSION: Pretreatment CT measurements of tumor volume permits stratification of patients with supraglottic SCC treated with RT alone (which allows preservation of laryngeal function) into groups in which local control is more likely and less likely. Pre-epiglottic space spread is not a contraindication to using RT as the primary treatment for supraglottic SCC. (+info)Sternothoracotomy for combined coronary artery bypass grafting and left upper lobectomy in a patient with low-lying tracheostoma. (5/1167)
A 64-year-old man had a low-lying tracheostoma and presented with unstable angina and a mass in the pulmonary left upper lobe. Simultaneous coronary revascularization and resection of the lung neoplasm were completed through a sternothoracotomy (clam-shell) incision. The advantages of this approach include excellent exposure to the mediastinum and the lung fields, and the option of using both internal thoracic arteries for bypass grafting. (+info)Suppression of extracellular signals and cell proliferation by the black tea polyphenol, theaflavin-3,3'-digallate. (6/1167)
Previous studies in our laboratory have shown that the major green tea polyphenol, (-)-epigallocatechin-3-gallate (EGCG), suppressed autophosphorylation of epidermal growth factor (EGF) receptor induced by EGF in human A431 epidermoid carcinoma cells. In this study, we examined the inhibitory effects of black tea polyphenols, including theaflavin (TF-1), a mixture (TF-2) of theaflavin-3-gallate (TF-2a) and theaflavin-3'-gallate (TF-2b), theaflavin-3,3'-digallate (TF-3) and the thearubigin fraction on the autophosphorylation of the EGF and PDGF receptors in A431 cells and mouse NIH3T3 fibroblast cells, respectively. First, we examined the effects of these polyphenols on the proliferation of A431 and NIH3T3 cells. Both EGCG and TF-3 strongly inhibited the proliferation of A431 and NIH3T3 cells more than the other theaflavins did. In cultured cells with pre-treatment of tea polyphenol, TF-3 was stronger than EGCG on the reduction of EGF receptor and PDGF receptor autophosphorylation induced by EGF and PDGF, respectively. Other theaflavins slightly reduced the autophosphorylation of the EGF and PDGF receptors; furthermore, TF-3 could reduce autophosphorylation of the EGF receptor (or PDGF receptor) even with co-treatment with EGF (or PDGF) and TF-3, but EGCG was inactive under these conditions. In addition, TF-3 was stronger than EGCG in blocking EGF binding to its receptor. These results suggest that not only the green tea polyphenol, EGCG, but also the black tea polyphenol, TF-3, have an antiproliferative activity on tumor cells, and the molecular mechanisms of antiproliferation may block the growth factor binding to its receptor and thus suppress mitogenic signal transduction. (+info)The difference between delayed extubation and tracheostomy in post-operative sleep apnea after glossectomy or laryngectomy. (7/1167)
BACKGROUND: Patients with cancer of the tongue or larynx require glossectomies or laryngectomies and subsequent reconstruction. These procedures remove part of the patient's upper airway. In cancer of the tongue, the removed part of the airway is substituted by a flap of their skin. Post-operatively, it is possible that the patients have problems respiring comfortably. In addition to this, long surgical procedures may simply interfere with their circadian rhythm. To elucidate the possible change in their post-operative respiration, we monitored the patient's respiratory pattern with an apnea monitor. METHODS: We attached an apnea monitor to the patients and recorded their respiratory pattern and arterial oxygen saturation. The patients were monitored for a total of five days: three days prior to the operation, one day before the operation, the day of operation, two days after, and on the fourth day after the operation. The period of monitoring was from 8:00 p.m. to 6:00 a.m. the next morning. RESULTS: Sixteen patients completed this study. The patients whose tube was extubated after glossectomy showed frequent apnea, low mean oxygen saturation and low comfort score as compared to the patients with tracheostomy after laryngectomy. Because two failed cases of free skin flap were among the former, it is possible that the frequent apnea is a factor of failed free skin graft after glossectomy and laryngectomy. CONCLUSION: Further studies are required to improve the patient's respiration during their sleep after tracheal extubation in glossectomy. (+info)Differential protection against benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide-induced DNA damage in HepG2 cells stably transfected with allelic variants of pi class human glutathione S-transferase. (8/1167)
The pi class glutathione S-transferase (GSTP1-1), which is polymorphic in human populations, is believed to play an important role in detoxification of the ultimate carcinogen of widespread environmental pollutant benzo[a]pyrene [(+)-anti-benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide [(+)-anti-BPDE]]. The allelic variants of human GSTP1-1 (hGSTP1-1) differ in their structures by the amino acids in positions 104 (isoleucine or valine) and/or 113 (valine or alanine). Here, we have determined the protective effect of overexpression of allelic variants of hGSTP1-1, through stable transfection in HepG2 cells, against (+)-anti-BPDE-induced DNA modification. Clonal transfectants of HepG2 cells corresponding to the three allelic variants of hGSTP1-1 [(I104,A113), (V104,A113), and (V104,V113), denoted hGSTP1(IA), hGSTP1(VA), and hGSTP1(VV), respectively] with similar levels of hGSTP1 protein were identified and characterized for their GST activity and (+)-anti-BPDE-induced DNA modification. The glutathione S-transferase activity toward (+)-anti-BPDE was significantly higher (approximately 3.0-3.6-fold) in cells transfected with hGSTP1(VA) [HepG2(VA)] and hGSTP1(VV) [HepG2(VV)] compared with hGSTP1(IA) transfectant [HepG2(IA)]. The formation of (+)-anti-BPDE-DNA adducts was significantly reduced in HepG2(VA) and HepG2(VV) cells compared with cells transfected with insert-free vector (HepG2-vect). Maximum protection against (+)-anti-BPDE-induced DNA damage was afforded by the hGSTP1(VV) isoform. The results of this study indicate that the allelic variants of hGSTP1-1 significantly differ in their ability to provide protection against (+)-anti-BPDE-induced DNA damage. Thus, hGSTP1-1 polymorphism may be an important factor in differential susceptibility of individuals to tumorigenesis induced by benzo[a]pyrene. (+info)Laryngeal neoplasms refer to abnormal growths or tumors in the larynx, also known as the voice box. These growths can be benign (non-cancerous) or malignant (cancerous). Laryngeal neoplasms can affect any part of the larynx, including the vocal cords, epiglottis, and the area around the vocal cords called the ventricle.
Benign laryngeal neoplasms may include papillomas, hemangiomas, or polyps. Malignant laryngeal neoplasms are typically squamous cell carcinomas, which account for more than 95% of all malignant laryngeal tumors. Other types of malignant laryngeal neoplasms include adenocarcinoma, sarcoma, and lymphoma.
Risk factors for developing laryngeal neoplasms include smoking, alcohol consumption, exposure to industrial chemicals, and a history of acid reflux. Symptoms may include hoarseness, difficulty swallowing, sore throat, ear pain, or a lump in the neck. Treatment options depend on the type, size, location, and stage of the neoplasm but may include surgery, radiation therapy, chemotherapy, or a combination of these treatments.
Sudden death is a term used to describe a situation where a person dies abruptly and unexpectedly, often within minutes to hours of the onset of symptoms. It is typically caused by cardiac or respiratory arrest, which can be brought on by various medical conditions such as heart disease, stroke, severe infections, drug overdose, or trauma. In some cases, the exact cause of sudden death may remain unknown even after a thorough post-mortem examination.
It is important to note that sudden death should not be confused with "sudden cardiac death," which specifically refers to deaths caused by the abrupt loss of heart function (cardiac arrest). Sudden cardiac death is often related to underlying heart conditions such as coronary artery disease, cardiomyopathy, or electrical abnormalities in the heart.
An autopsy, also known as a post-mortem examination or obduction, is a medical procedure in which a qualified professional (usually a pathologist) examines a deceased person's body to determine the cause and manner of death. This process may involve various investigative techniques, such as incisions to study internal organs, tissue sampling, microscopic examination, toxicology testing, and other laboratory analyses. The primary purpose of an autopsy is to gather objective evidence about the medical conditions and factors contributing to the individual's demise, which can be essential for legal, insurance, or public health purposes. Additionally, autopsies can provide valuable insights into disease processes and aid in advancing medical knowledge.
Bereavement is the state of loss or grief experienced when a person experiences the death of a loved one, friend, or family member. It is a normal response to the death of someone close and can involve a range of emotions such as sadness, anger, guilt, and anxiety. The grieving process can be different for everyone and can take time to work through. Professional support may be sought to help cope with the loss.
A coroner and medical examiner are officials in the legal system who are responsible for investigating and determining the cause of death in certain cases. While their roles can overlap, there are some differences between them.
A coroner is a public official who is typically appointed or elected to serve in a particular jurisdiction, such as a county or district. The coroner's primary responsibility is to investigate any sudden, unexpected, or suspicious deaths that occur within their jurisdiction. This may include deaths that occur due to violence, accidents, suicide, or unknown causes.
In order to determine the cause of death, the coroner may conduct an autopsy, order toxicology tests, and review medical records and other evidence. The coroner may also hold an inquest, which is a formal hearing in which witnesses are called to testify about the circumstances surrounding the death. Based on the evidence gathered during the investigation, the coroner will make a determination as to the cause and manner of death.
A medical examiner, on the other hand, is a physician who has completed specialized training in forensic pathology. Medical examiners are typically appointed or hired by a government agency, such as a state or county, to perform autopsies and investigate deaths.
Medical examiners are responsible for determining the cause of death in cases where there is a suspicion of foul play, as well as in other circumstances where the cause of death may not be immediately apparent. They may also testify in court as expert witnesses based on their findings.
In some jurisdictions, the roles of coroner and medical examiner are combined, with the official serving as both a public administrator and a trained physician. In other cases, the two roles are separate, with the coroner responsible for administrative functions and the medical examiner responsible for determining the cause of death.
Forensic pathology is a subspecialty of pathology that focuses on determining the cause and manner of death by examining a corpse. It involves applying scientific knowledge and techniques to investigate criminal or suspicious deaths, often in conjunction with law enforcement agencies. A forensic pathologist performs autopsies (postmortem examinations) to evaluate internal and external injuries, diseases, and other conditions that may have contributed to the individual's death. They also collect evidence such as tissue samples, which can be used for toxicological, microbiological, or histological analysis. The information gathered by forensic pathologists is crucial in helping to establish the facts surrounding a person's death and assisting legal proceedings.
The "cause of death" is a medical determination of the disease, injury, or event that directly results in a person's death. This information is typically documented on a death certificate and may be used for public health surveillance, research, and legal purposes. The cause of death is usually determined by a physician based on their clinical judgment and any available medical evidence, such as laboratory test results, autopsy findings, or eyewitness accounts. In some cases, the cause of death may be uncertain or unknown, and the death may be classified as "natural," "accidental," "homicide," or "suicide" based on the available information.
"Terminology as a topic" in the context of medical education and practice refers to the study and use of specialized language and terms within the field of medicine. This includes understanding the meaning, origins, and appropriate usage of medical terminology in order to effectively communicate among healthcare professionals and with patients. It may also involve studying the evolution and cultural significance of medical terminology. The importance of "terminology as a topic" lies in promoting clear and accurate communication, which is essential for providing safe and effective patient care.
