Actinomyces and nocardia infections in immunocompromised and nonimmunocompromised patients. (1/212)
A retrospective survey of nocardia and actinomyces infections in five local hospitals was conducted over a 3-year period in El Paso, Texas, a border city, in the southwestern United States. The medical records of 42 patients with suspected nocardiosis or actinomycosis were reviewed. One patient was diagnosed with actinomyces and 12 patients with nocardia. Microbiological data included morphologic characteristics, biochemical profile, and susceptibility testing. Predisposing factors included leukemia, renal insufficiency, renal transplant, and lymphoma. No predisposing factors were found in 67% (n = 8) of patients (including the patient with actinomycosis). Twenty-three percent (n = 3) of patients had disseminated disease without evidence of underlying disease or immunosuppression. The mortality and morbidity of these infections appeared to be low. (+info)Pathogenesis of cancrum oris (noma): confounding interactions of malnutrition with infection. (2/212)
This study showed that impoverished Nigerian children at risk for cancrum oris (noma) had significantly reduced plasma concentrations of zinc (< 10.8 micromol/L), retinol (< 1.05 micromol/L), ascorbate (< 11 micromol/L), and the essential amino acids, with prominently increased plasma and saliva levels of free cortisol, compared with their healthy counterparts. The nutrient deficiencies, in concert with previously reported widespread viral infections (measles, herpesviruses) in the children, would impair oral mucosal immunity. We postulate, subject to additional studies, that evolution of the oral mucosal ulcers including acute necrotizing gingivitis to noma is triggered by a consortium of microorganisms of which Fusobacterium necrophorum is a key component. Fusobacterium necrophorum elaborates several dermonecrotic toxic metabolites and is acquired by the impoverished children via fecal contamination resulting from shared residential facilities with animals and very poor environmental sanitation. (+info)Childhood actinomycosis. Report of 3 recent cases. (3/212)
Three cases of childhood actinomycosis are reported, 2 with the commonest presentation of cervicofacial abscess and the third with a rarely reported superficial chest wall abscess. The importance of prompt bacteriological diagnosis and adequate treatment with surgical drainage and chemotherapy is stressed. Though in adults males are affected more frequently than females, the sexes are probably equally affected in childhood. (+info)Endobronchial actinomycosis simulating endobronchial tuberculosis: a case report. (4/212)
We report a case of a 70-year-old woman who presented with mild exertional dyspnea and cough. Fiberoptic bronchoscopic findings revealed an endobronchial polypoid lesion with stenotic bronchus. The lesion was very similar to endobronchial tuberculosis. Histologic examination of the biopsy specimen demonstrated Actinomyces infection. There was a clinical response to intravenous penicillin therapy. Primary endobronchial actinomycosis must be considered in the differential diagnosis of an endobronchial lesion, especially endobronchial tuberculosis in Korea. (+info)Actinomyces bowdenii sp. nov., isolated from canine and feline clinical specimens. (5/212)
Four strains of a previously undescribed Actinomyces-like bacterium were isolated from canine and feline clinical specimens. Phenotypic studies indicated the strains were members of the genus Actinomyces, and most closely resembled Actinomyces viscosus serotype I and Actinomyces slackii. Comparative 16S rRNA gene sequencing studies demonstrated the unknown bacterium constitutes a new subline within a group of Actinomyces species, which includes Actinomyces bovis, the type species of the genus. Based on phylogenetic and phenotypic evidence it is proposed that the unknown bacterium be classified as Actinomyces bowdenii sp. nov. The type strain of Actinomyces bowdenii is CCUG 37421T. (+info)Infection of a hip prosthesis by Actinomyces naeslundii. (6/212)
We present the case of a 77-year-old woman who developed an Actinomyces naeslundii infection of a hip prosthesis. The isolate grew well aerobically with 5% CO(2). Possible diagnostic problems may arise in the microbiological laboratory because aerobic growth is not sufficiently accounted for in some of the traditional identification schemes and commercial test kits. Therefore, besides presenting an unusual pathogen in this setting, this report focuses on possible diagnostic problems in the microbiological laboratory. (+info)Molecular and genetic analyses of Actinomyces spp. (7/212)
Members of the genus Actinomyces are predominant primary colonizers of the oral cavity and play an important role in initiating plaque development. These bacteria have evolved unique mechanisms that favor colonization and persistence in this micro-environment. The expression of cell-surface fimbriae is correlated with the ability of these bacteria to adhere to specific receptors on the tooth and mucosal surfaces, and to interact with other plaque bacteria. The elaboration of sialidase is thought to enhance fimbriae-mediated adherence by unmasking the fimbrial receptors on mammalian cells. The presence of certain cell-associated or extracellular enzymes, including those involved in sucrose or urea metabolism, may provide the means for these bacteria to thrive under conditions when other growth nutrients are not available. Moreover, these enzyme activities may influence the distribution of other plaque bacteria and promote selection for Actinomyces spp. in certain ecological niches. The recent development of a genetic transfer system for Actinomyces spp. has allowed for studies the results of which demonstrate the existence of multiple genes involved in fimbriae synthesis and function, and facilitated the construction of allelic replacement mutants at each gene locus. Analyses of these mutants have revealed a direct correlation between the synthesis of assembled fimbriae and the observed adherence properties. Further genetic analysis of the various enzyme activities detected from strains of Actinomyces should allow for an assessment of the role of these components in microbial ecology, and their contribution to the overall success of Actinomyces spp. as a primary colonizer and a key player in oral health and disease. (+info)Actinomyces canis sp. nov., isolated from dogs. (8/212)
Three strains of a previously undescribed catalase-positive Actinomyces-like bacterium were isolated from dogs. Biochemical testing and PAGE analysis of whole-cell proteins indicated that the strains were phenotypically highly related to each other but different from previously described Actinomyces and Arcanobacterium species. Sequencing of 16S rRNA showed that the unknown bacterium represents a new subline within a cluster of species which includes Actinomyces hyovaginalis, Actinomyces georgiae, Actinomyces meyeri, Actinomyces odontolyticus, Actinomyces radingae and Actinomyces turicensis. On the basis of phenotypic evidence and 16S rRNA sequence divergence levels (greater than 5% with recognized Actinomyces species) it is proposed that the unknown strains from canine sources be classified as a new species with the name Actinomyces canis sp. nov. The type strain of Actinomyces canis is CCUG 41706T (= CIP 106351T). (+info)Actinomycosis is a type of infection caused by bacteria that are normally found in the mouth, intestines, and female genital tract. These bacteria can cause abscesses or chronic inflammation if they infect body tissues, often after trauma or surgery. The infection typically affects the face, neck, or chest, and can spread to other parts of the body over time. Symptoms may include swelling, redness, pain, and the formation of pus-filled abscesses that may discharge a characteristic yellowish granular material called "sulfur granules." Treatment typically involves long-term antibiotic therapy, often requiring high doses and intravenous administration. Surgical drainage or removal of infected tissue may also be necessary in some cases.
Cervicofacial actinomycosis is a form of actinomycosis, which is a type of infection caused by the Actinomyces species of bacteria. These bacteria are normally found in the mouth, throat, and digestive system and are usually harmless. However, they can cause an infection if they are able to penetrate the mucosal lining of these areas, such as through trauma or injury.
Cervicofacial actinomycosis specifically affects the head and neck region. It often presents as a slowly progressive, painful, indurated (hardened) mass in the cervicofacial area, which can be accompanied by symptoms such as fever, weight loss, and fatigue. The infection can spread to surrounding tissues, including bone and muscle, and can form abscesses or fistulas that drain pus.
Cervicofacial actinomycosis is typically treated with high-dose antibiotics for an extended period of time, often several months. Surgical intervention may also be necessary to remove any areas of necrotic (dead) tissue or to drain abscesses. The prognosis for cervicofacial actinomycosis is generally good with appropriate treatment, although the infection can recur if not fully treated.
Actinomyces is a genus of gram-positive, rod-shaped bacteria that are normal inhabitants of the human mouth, colon, and urogenital tract. Under certain conditions, such as poor oral hygiene or tissue trauma, these bacteria can cause infections known as actinomycosis. These infections often involve the formation of abscesses or granulomas and can affect various tissues, including the lungs, mouth, and female reproductive organs. Actinomyces species are also known to form complex communities called biofilms, which can contribute to their ability to cause infection.
An Intrauterine Device (IUD) is a long-acting, reversible contraceptive device that is inserted into the uterus to prevent pregnancy. It is a small T-shaped piece of flexible plastic with strings attached to it for removal. There are two types of IUDs available: hormonal and copper. Hormonal IUDs release progestin, which thickens cervical mucus and thins the lining of the uterus, preventing sperm from reaching and fertilizing an egg. Copper IUDs, on the other hand, produce an inflammatory reaction in the uterus that is toxic to sperm and eggs, preventing fertilization.
IUDs are more than 99% effective at preventing pregnancy and can remain in place for several years, depending on the type. They are easily removable by a healthcare provider if a woman wants to become pregnant or choose another form of contraception. IUDs do not protect against sexually transmitted infections (STIs), so it is important to use condoms in addition to an IUD for protection against STIs.
In summary, Intrauterine Devices are small, T-shaped plastic devices that are inserted into the uterus to prevent pregnancy. They come in two types: hormonal and copper, both of which work by preventing fertilization. IUDs are highly effective, long-acting, and reversible forms of contraception.
Pelvic Inflammatory Disease (PID) is a medical condition characterized by inflammation of the reproductive organs in women, specifically the uterus, fallopian tubes, and/or ovaries. It is often caused by an infection that ascends from the cervix or vagina into the upper genital tract. The infectious agents are usually sexually transmitted bacteria such as Neisseria gonorrhoeae and Chlamydia trachomatis, but other organisms can also be responsible.
Symptoms of PID may include lower abdominal pain, irregular menstrual bleeding, vaginal discharge with an unpleasant odor, fever, painful sexual intercourse, or pain in the lower back. However, some women with PID may not experience any symptoms at all. If left untreated, PID can lead to serious complications such as infertility, ectopic pregnancy, and chronic pelvic pain.
Diagnosis of PID is typically based on a combination of clinical findings, physical examination, and laboratory tests. Treatment usually involves antibiotics to eradicate the infection and may also include pain management and other supportive measures. In some cases, hospitalization may be necessary for more intensive treatment or if complications arise.
Bronchial diseases refer to medical conditions that affect the bronchi, which are the large airways that lead into the lungs. These diseases can cause inflammation, narrowing, or obstruction of the bronchi, leading to symptoms such as coughing, wheezing, chest tightness, and difficulty breathing.
Some common bronchial diseases include:
1. Asthma: A chronic inflammatory disease of the airways that causes recurring episodes of wheezing, breathlessness, chest tightness, and coughing.
2. Chronic Bronchitis: A long-term inflammation of the bronchi that leads to a persistent cough and excessive mucus production.
3. Bronchiectasis: A condition in which the bronchi become damaged and widened, leading to chronic infection and inflammation.
4. Bronchitis: An inflammation of the bronchi that can cause coughing, wheezing, and chest tightness.
5. Emphysema: A lung condition that causes shortness of breath due to damage to the air sacs in the lungs. While not strictly a bronchial disease, it is often associated with chronic bronchitis and COPD (Chronic Obstructive Pulmonary Disease).
Treatment for bronchial diseases may include medications such as bronchodilators, corticosteroids, or antibiotics, as well as lifestyle changes such as quitting smoking and avoiding irritants. In severe cases, oxygen therapy or surgery may be necessary.
Oophoritis is a medical term that refers to the inflammation of one or both ovaries. It is often caused by an infection, which can be bacterial, viral, or fungal in nature. The infection can spread to the ovaries from other parts of the reproductive system, such as the fallopian tubes or the uterus.
Oophoritis can cause symptoms such as pelvic pain, abdominal cramping, irregular menstrual bleeding, and fever. In some cases, it may lead to complications such as infertility or chronic pelvic pain. Treatment typically involves antibiotics to clear the infection, as well as pain relief medications and anti-inflammatory drugs to manage symptoms.
It is important to note that oophoritis can be a serious condition, especially if left untreated. If you are experiencing any symptoms of oophoritis, it is important to seek medical attention promptly.
A pelvic infection, also known as pelvic inflammatory disease (PID), is a medical condition characterized by inflammation of the reproductive organs in females, including the uterus, fallopian tubes, ovaries, and surrounding tissues. It is often caused by an ascending infection from the cervix or vagina, commonly due to sexually transmitted bacteria such as Neisseria gonorrhoeae and Chlamydia trachomatis. However, other organisms can also cause pelvic infections.
Symptoms of pelvic infections may include lower abdominal pain, irregular menstrual bleeding, vaginal discharge with an unpleasant odor, fever, painful intercourse, and difficulty urinating. In some cases, pelvic infections may not cause any noticeable symptoms, making it challenging to diagnose the condition promptly.
If left untreated, pelvic infections can lead to serious complications such as chronic pelvic pain, infertility, ectopic pregnancy, and abscess formation in the reproductive organs. Treatment typically involves antibiotics to eradicate the infection, and in severe cases, hospitalization and surgical intervention may be necessary.
Actinomyces viscosus is a gram-positive, anaerobic, rod-shaped bacterium that is commonly found in the oral cavity and upper respiratory tract of humans. It is a normal resident of the human microbiota but can cause infections in immunocompromised individuals or when it gains access to deeper tissues, such as the pulp of teeth or the soft tissues of the head and neck.
Actinomyces viscosus has been associated with dental caries, periodontal disease, and endodontic infections. It can also cause actinomycosis, a chronic suppurative and granulomatous infection that typically affects the cervicofacial region, thorax, or abdomen.
The name "viscosus" refers to the sticky, mucoid appearance of the bacterial colonies when grown in culture. Actinomyces viscosus is closely related to other species of Actinomyces, such as A. israelii and A. gerencseriae, which can also cause actinomycosis.
Bacterial skin diseases are a type of infectious skin condition caused by various species of bacteria. These bacteria can multiply rapidly on the skin's surface when given the right conditions, leading to infection and inflammation. Some common bacterial skin diseases include:
1. Impetigo: A highly contagious superficial skin infection that typically affects exposed areas such as the face, hands, and feet. It is commonly caused by Staphylococcus aureus or Streptococcus pyogenes bacteria.
2. Cellulitis: A deep-skin infection that can spread rapidly and involves the inner layers of the skin and underlying tissue. It is often caused by Group A Streptococcus or Staphylococcus aureus bacteria.
3. Folliculitis: An inflammation of hair follicles, usually caused by an infection with Staphylococcus aureus or other bacteria.
4. Furuncles (boils) and carbuncles: Deep infections that develop from folliculitis when the infection spreads to surrounding tissue. A furuncle is a single boil, while a carbuncle is a cluster of boils.
5. Erysipelas: A superficial skin infection characterized by redness, swelling, and warmth in the affected area. It is typically caused by Group A Streptococcus bacteria.
6. MRSA (Methicillin-resistant Staphylococcus aureus) infections: Skin infections caused by a strain of Staphylococcus aureus that has developed resistance to many antibiotics, making it more difficult to treat.
7. Leptospirosis: A bacterial infection transmitted through contact with contaminated water or soil and characterized by flu-like symptoms and skin rashes.
Treatment for bacterial skin diseases usually involves the use of topical or oral antibiotics, depending on the severity and location of the infection. In some cases, drainage of pus-filled abscesses may be necessary to promote healing. Proper hygiene and wound care can help prevent the spread of these infections.
The ascending colon is the first part of the large intestine, which is the portion of the digestive system that follows the small intestine. It is called "ascending" because it travels upward from the right side of the abdomen toward the underside of the liver. The primary function of the ascending colon is to absorb water and electrolytes from digested food and prepare waste for elimination.
Lung diseases refer to a broad category of disorders that affect the lungs and other structures within the respiratory system. These diseases can impair lung function, leading to symptoms such as coughing, shortness of breath, chest pain, and wheezing. They can be categorized into several types based on the underlying cause and nature of the disease process. Some common examples include:
1. Obstructive lung diseases: These are characterized by narrowing or blockage of the airways, making it difficult to breathe out. Examples include chronic obstructive pulmonary disease (COPD), asthma, bronchiectasis, and cystic fibrosis.
2. Restrictive lung diseases: These involve stiffening or scarring of the lungs, which reduces their ability to expand and take in air. Examples include idiopathic pulmonary fibrosis, sarcoidosis, and asbestosis.
3. Infectious lung diseases: These are caused by bacteria, viruses, fungi, or parasites that infect the lungs. Examples include pneumonia, tuberculosis, and influenza.
4. Vascular lung diseases: These affect the blood vessels in the lungs, impairing oxygen exchange. Examples include pulmonary embolism, pulmonary hypertension, and chronic thromboembolic pulmonary hypertension (CTEPH).
5. Neoplastic lung diseases: These involve abnormal growth of cells within the lungs, leading to cancer. Examples include small cell lung cancer, non-small cell lung cancer, and mesothelioma.
6. Other lung diseases: These include interstitial lung diseases, pleural effusions, and rare disorders such as pulmonary alveolar proteinosis and lymphangioleiomyomatosis (LAM).
It is important to note that this list is not exhaustive, and there are many other conditions that can affect the lungs. Proper diagnosis and treatment of lung diseases require consultation with a healthcare professional, such as a pulmonologist or respiratory therapist.
Penicillins are a group of antibiotics derived from the Penicillium fungus. They are widely used to treat various bacterial infections due to their bactericidal activity, which means they kill bacteria by interfering with the synthesis of their cell walls. The first penicillin, benzylpenicillin (also known as penicillin G), was discovered in 1928 by Sir Alexander Fleming. Since then, numerous semi-synthetic penicillins have been developed to expand the spectrum of activity and stability against bacterial enzymes that can inactivate these drugs.
Penicillins are classified into several groups based on their chemical structure and spectrum of activity:
1. Natural Penicillins (e.g., benzylpenicillin, phenoxymethylpenicillin): These have a narrow spectrum of activity, mainly targeting Gram-positive bacteria such as streptococci and staphylococci. However, they are susceptible to degradation by beta-lactamase enzymes produced by some bacteria.
2. Penicillinase-resistant Penicillins (e.g., methicillin, oxacillin, nafcillin): These penicillins resist degradation by certain bacterial beta-lactamases and are primarily used to treat infections caused by staphylococci, including methicillin-susceptible Staphylococcus aureus (MSSA).
3. Aminopenicillins (e.g., ampicillin, amoxicillin): These penicillins have an extended spectrum of activity compared to natural penicillins, including some Gram-negative bacteria such as Escherichia coli and Haemophilus influenzae. However, they are still susceptible to degradation by many beta-lactamases.
4. Antipseudomonal Penicillins (e.g., carbenicillin, ticarcillin): These penicillins have activity against Pseudomonas aeruginosa and other Gram-negative bacteria with increased resistance to other antibiotics. They are often combined with beta-lactamase inhibitors such as clavulanate or tazobactam to protect them from degradation.
5. Extended-spectrum Penicillins (e.g., piperacillin): These penicillins have a broad spectrum of activity, including many Gram-positive and Gram-negative bacteria. They are often combined with beta-lactamase inhibitors to protect them from degradation.
Penicillins are generally well-tolerated antibiotics; however, they can cause allergic reactions in some individuals, ranging from mild skin rashes to life-threatening anaphylaxis. Cross-reactivity between different penicillin classes and other beta-lactam antibiotics (e.g., cephalosporins) is possible but varies depending on the specific drugs involved.
An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.
Actinomycetaceae is a family of Gram-positive, rod-shaped bacteria that are characterized by their filamentous growth and the production of branching hyphae. These bacteria are often found in soil and water, and some species can cause disease in humans and animals. They are classified as aerobic or facultatively anaerobic organisms, meaning they can grow with or without oxygen.
The name "Actinomycetaceae" comes from the Greek words "aktis," meaning "ray" or "beam," and "mykes," meaning "fungus." This reflects the filamentous, fungus-like growth of these bacteria.
Some species of Actinomycetaceae are known to produce various antibiotics, including streptomycin, neomycin, and tetracycline. These antibiotics have been widely used in medicine to treat a variety of bacterial infections.
In humans, some species of Actinomycetaceae can cause actinomycosis, a chronic infection that typically affects the face, neck, and mouth. Symptoms of actinomycosis include swelling, pain, and the formation of abscesses or fistulas. Treatment usually involves long-term antibiotic therapy and sometimes surgical drainage of any abscesses.
Overall, Actinomycetaceae is an important family of bacteria with both beneficial and harmful effects on humans and other organisms.
Propionibacterium is a genus of gram-positive, rod-shaped bacteria that are commonly found on the skin and in the mouth, intestines, and genitourinary tract of humans and animals. They are named after their ability to produce propionic acid as a major metabolic end product. Some species of Propionibacterium, such as P. acnes, are associated with skin conditions like acne vulgaris, where they contribute to the inflammatory response that leads to the formation of pimples and lesions. Other species, such as P. freudenreichii, are used in the food industry for the production of dairy products like Swiss cheese and yogurt. Propionibacterium species are generally considered to be non-pathogenic or opportunistic pathogens, meaning that they can cause infection under certain circumstances, such as when the immune system is compromised.

Bacteria2
- Bacteria that masquerade as fungi: actinomycosis/nocardia. (medscape.com)
- EPIDEMIOLOGY - Actinomycosis is an uncommon, chronic granulomatous disease caused by filamentous, gram-positive, anaerobic bacteria [ 1 ]. (medilib.ir)
Clinical2
- CLINICAL MANIFESTATIONS - Actinomycosis is a difficult disease to diagnose preoperatively by virtue of its rarity, nonspecific symptoms, and imitation of more common conditions such as malignancy, Crohn's disease, and tuberculosis. (medilib.ir)
- gt;We present a patient with actinomycosis of the parotid, as confirmed by histology and discuss the challenges involved when clinical and radiological findings are highly indicative of metastatic malignancy. (uwi.edu)
Infections2
- However, in some cases actinomycosis can be locally destructive and progress to generalized infections, causing complications including abscess formation with risk of rupture, fistula formation, or spread to neighboring and distant organs. (medscape.com)
- Actinomycosis is an uncommon disease in children and most cases are cervicofacial infections. (omu.edu.tr)
Abdominopelvic2
- In addition, there have been multiple reports of abdominopelvic actinomycosis associated with the use of intrauterine contraceptive devices [ 3-5 ]. (medilib.ir)
- We present the case of an elderly female who underwent a workup for acute blood loss anemia that incidentally led to the discovery of abdominopelvic actinomycosis. (londonspine.com)
Symptoms2
- Empyema due to actinomycosis is relatively rare and can be difficult to diagnose as the presenting symptoms may be indolent and the micro-organism may be difficult to culture. (bmj.com)
- In a retrospective investigation performed in the department of Surgical Odontostomatology of Palermo University Polyclinic from 2012 to 2021, the Author examined 10 cases of cervico-facial actinomycosis, taking into consideration age range, gender distribution, predisposing factors and symptoms. (unipa.it)
Pelvis1
- Actinomycosis of the abdomen and pelvis accounts for 10-20% of reported cases. (medscape.com)
Penicillin3
- In the treatment of actinomycosis, tetracyclines are as effective as penicillin. (medscape.com)
- High-dose penicillin administered over a prolonged period (6 months to 1 year) is the cornerstone of therapy for actinomycosis. (medscape.com)
- High-dose penicillin is the treatment of choice for actinomycosis. (pediagenosis.com)
Organs2
- Hematogenous dissemination to distant organs may occur in any stage of actinomycosis, whereas lymphatic dissemination is unusual. (medscape.com)
- Imaging of actinomycosis in various organs: a comprehensive review. (medscape.com)
Predispose1
- An affected human often has recently had dental work, poor oral hygiene, periodontal disease, radiation therapy, or trauma (broken jaw) causing local tissue damage to the oral mucosa, all of which predispose the person to developing actinomycosis. (wikipedia.org)
Affects2
- Because of the bacteria's normal location in the nose and throat, actinomycosis most commonly affects the face and neck. (medlineplus.gov)
- Actinomycosis has a worldwide distribution, affects mostly middle-aged individuals, and is two to four times more common in men [ 2-4 ]. (medilib.ir)
Manifestations2
- Specifically, they may be responsible for the early manifestations of actinomycosis and for treatment failures. (medscape.com)
- The presence of extraintestinal manifestations of inflammatory bowel disease (eg, uveitis, ankylosing spondylitis) may be helpful in distinguishing ileocecal Crohn's disease from actinomycosis. (medilib.ir)
Dermatology1
- For additional information on actinomycosis, see the articles Actinomycosis (dermatology focus), Actinomycosis (pediatrics focus), and Actinomycosis (ophthalmology focus). (medscape.com)
Incidence2
- The use of intrauterine devices (IUDs) has increased incidence of genitourinary actinomycosis in females. (wikipedia.org)
- Incidence of oral actinomycosis, which is harder to diagnose, has increased. (wikipedia.org)
Nocardiosis1
- Called "great masqueraders," diagnosis of actinomycosis and nocardiosis is often delayed. (qxmd.com)
Treatment3
- The treatment of actinomycosis may require extended antibiotic therapy and surgical interventions as pertinent. (medscape.com)
- Surgical management in actinomycosis has consisted of various treatment modalities, including excision of sinus tracts, drainage of the abscess cavities, removal of bulky infected masses, and irrigation and curettage of the osteomyelitic bony lesions. (medscape.com)
- DOC for treatment of actinomycosis. (medscape.com)
Typically1
- These recommendations were developed at a time when patients with actinomycosis typically presented late in the course of illness with large lesions, often receiving intermittent antibiotic therapy. (medscape.com)
Infectious1
- Actinomycosis is an infectious disease which can spread from one part of our body to another through the tissues. (chennaihyperbaricclinic.com)
Cases2
- In rare cases, meningitis can develop from actinomycosis. (medlineplus.gov)
- Abnormal vaginal flora was found in 4.8% of cases, Candida albicans in 1.2%, Tri- chomonas vaginalis in 0.9% and actinomycosis in 1 case. (who.int)
Lungs1
- Clues in differentiating TB from actinomycosis include the presence of multisystem involvement (eg, lungs) in patients at high risk for TB. (medilib.ir)
Chest wall1
- To date, there have been only a few reports on children with chest wall involvement due to actinomycosis. (omu.edu.tr)
Tracts2
- A hallmark of actinomycosis is the tendency to spread through anatomic barriers, including fascial planes, and the development of multiple sinus tracts. (pediagenosis.com)
- Actinomycosis is caused by bacterium that is already present in our bodies but in select places such as mouth, throat, digestive and urinary tracts. (chennaihyperbaricclinic.com)
