Small Intestinal Bacterial Overgrowth
Small intestinal bacterial overgrowth (SIBO), also termed bacterial overgrowth, or small bowel bacterial overgrowth syndrome (SBBOS), is a disorder of excessive bacterial growth in the small intestine. Unlike the colon (or large bowel), which is rich with bacteria, the small bowel usually has fewer than 100,000 organisms per millilitre. Patients with bacterial overgrowth typically develop symptoms which may include nausea, bloating, vomiting, diarrhea, malnutrition, weight loss and malabsorption, which is caused by a number of mechanisms. The diagnosis of bacterial overgrowth is made by a number of techniques, with the gold standard being an aspirate from the jejunum that grows in excess of 105 bacteria per millilitre. Risk factors for the development of bacterial overgrowth include dysmotility; anatomical disturbances in the bowel, including fistulae, diverticula and blind loops created after surgery, and resection of the ileo-cecal valve; gastroenteritis-induced alterations to ...

Gingival Overgrowth
Gingival enlargement is an increase in the size of the gingiva (gums). It is a common feature of gingival disease. Gingival enlargement can be caused by a number of factors, including inflammatory conditions and the side effects of certain medications. The treatment is based on the cause. A closely related term is epulis, denoting a localized tumor (i.e. lump) on the gingiva. Classification The terms gingival hyperplasia and gingival hypertrophy have been used to describe this topic in the past. These are not precise descriptions of gingival enlargement because these terms are strictly histologic diagnoses, and such diagnoses require microscopic analysis of a tissue sample. Hyperplasia refers to an increased number of cells, and hypertrophy refers to an increase in the size of individual cells. As these identifications cannot be performed with a clinical examination and evaluation of the tissue, the term ''gingival enlargement'' is more properly applied. Gingival enlargeme ...

Overgrowth Syndrome
Overgrowth syndromes in children constitute a group of rare disorders that are characterised by tissue hypertrophy. Individual overgrowth syndromes have been shown to overlap with regard to clinical and radiologic features. The details of the genetic bases of these syndromes are unfolding. Any of the three embryonic tissue layers may be involved. The syndromes may manifest in localized or generalized tissue overgrowth. Latitudinal and longitudinal growth may be affected.Lacerda L da S, Alves ÚD, Zanier JFC, Machado DC, Camilo GB, Lopes AJ (2014)"Differential diagnoses of overgrowth syndromes: The most important clinical and radiological disease manifestations" ''Radiol Res Pract''. 2014:947451. . . Nevertheless, the musculoskeletal features are central to the diagnosis of some syndromes such as Proteus syndrome.EL-Sobky TA, Elsayed SM, EL Mikkawy DME (2015)"Orthopaedic manifestations of Proteus syndrome in a child with literature update" ''Bone Rep''. 3:104-108. . . .

Achlorhydria
Achlorhydria and hypochlorhydria refer to states where the production of hydrochloric acid in gastric secretions of the stomach and other digestive organs is absent or low, respectively. It is associated with various other medical problems. Signs and symptoms Irrespective of the cause, achlorhydria can result as known complications of bacterial overgrowth and intestinal metaplasia and symptoms are often consistent with those diseases: *gastroesophageal reflux disease *abdominal discomfort *early satiety *weight loss *diarrhea *constipation *abdominal bloating *anemia *stomach infection *malabsorption of food *carcinoma of stomach Since acidic pH facilitates the absorption of iron, achlorhydric patients often develop iron deficiency anemia. Acidic environment of stomach helps conversion of pepsinogen into pepsin, which is highly important in digesting the protein into smaller components, such as a complex protein into simple peptides and amino acids inside the stomach, which ar ...

Perlman Syndrome
Perlman syndrome (PS) (also called renal hamartomas, nephroblastomatosis and fetal gigantism) is a rare overgrowth disorder present at birth. It is characterized by polyhydramnios and fetal overgrowth, including macrocephaly, neonatal macrosomia, visceromegaly, dysmorphic facial features, and an increased risk for Wilms' tumor at an early age. The prognosis for Perlman syndrome is poor and it is associated with a high neonatal mortality. Perlman syndrome is an uncommon genetic disorder grouped with overgrowth syndrome in which an abnormal increase is often noted at birth in the size of the body or a body part of the infant. The disorder, also called renal hamartomas, nephroblastomatosis and fetal gigantism, has also been grouped with Renal cell carcinoma. The characteristic features include polyhydramnios, fetal overgrowth, including macrocephaly, neonatal macrosomia, visceromegaly, dysmorphic facial features, and an increased risk for Wilms' tumor at an early age. Signs an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hereditary Gingival Fibromatosis
Hereditary gingival fibromatosis (HGF), also known as idiopathic gingival hyperplasia, is a rare condition of gingival overgrowth.Poulami Majumder, Vineet Nair, Malancha Mukherjee, Sujoy Ghosh, and Subrata Kumar Dey, "The Autosomal Recessive Inheritance of Hereditary Gingival Fibromatosis", Case Reports in Dentistry, vol. 2013, Article ID 432864, 4 pages, 2013. doi:10.1155/2013/432864 HGF is characterized as a benign, slowly progressive, nonhemorrhagic, fibrous enlargement of keratinized gingiva. It can cover teeth in various degrees, and can lead to aesthetic disfigurement.Thomas C. Hart, Yingze Zhang, Michael C. Gorry, P. Suzanne Hart, Margaret Cooper, Mary L. Marazita, Jared M. Marks, Jose R. Cortelli, Debora Pallos Am J Hum Genet. 2002 April; 70(4): 943–954. Published online 2002 February 26. Fibrous enlargement is most common in areas of maxillary and mandibular tissues of both arches in the mouth. Phenotype and genotype frequency of HGF is 1:175,000 where males and females ...

Leontiasis Ossea
Leontiasis ossea, also known as leontiasis, lion face or lion face syndrome, is a rare medical condition, characterized by an overgrowth of the Face, facial and Human cranium, cranial bones. It is not a disease in itself, but a symptom of other diseases, including Paget's disease of bone, Paget's disease, fibrous dysplasia, hyperparathyroidism and renal osteodystrophy. The common form is that in which one or other maxilla is affected, its size progressively increasing, and thus encroaching on the cavities of the orbit, the mouth, the nose and its accessory sinuses. Exophthalmos gradually develops, going on later to a complete loss of sight due to compression of the optic nerve by the overgrowth of bone. There may also be interference with the Human nose, nasal Respiration (physiology), respiration and with the taking of food. In the somewhat less common form of this rare disease the overgrowth of bone affects all the cranial bones as well as those of the face, the senses being lost ...

Retinopathy
Retinopathy is any damage to the retina of the eyes, which may cause vision impairment. Retinopathy often refers to retinal vascular disease, or damage to the retina caused by abnormal blood flow. Age-related macular degeneration is technically included under the umbrella term retinopathy but is often discussed as a separate entity. Retinopathy, or retinal vascular disease, can be broadly categorized into proliferative and non-proliferative types. Frequently, retinopathy is an ocular manifestation of systemic disease as seen in diabetes or hypertension. Diabetes is the most common cause of retinopathy in the U.S. as of 2008. Diabetic retinopathy is the leading cause of blindness in working-aged people. It accounts for about 5% of blindness worldwide and is designated a priority eye disease by the World Health Organization. Signs and symptoms Many people often do not have symptoms until very late in their disease course. Patients often become symptomatic when there is irreversibl ...

Inflammatory Papillary Hyperplasia
Inflammatory papillary hyperplasia (IPH) is a benign lesion of the oral mucosa which is characterized by the growth of one or more nodular lesions, measuring about 2mm or less. The lesion almost exclusively involves the hard palate, and in rare instances, it also has been seen on the mandible. The lesion is mostly asymptomatic and color of the mucosa may vary from pink to red. In general, IPH is associated with the use of removable upper dentures, although it also has been found in dentulous patients with no history of a dental prosthesis. The majority of lesions are found beneath ill-fitting dentures of long use and in patients who do not take their dentures out overnight. The lesion seems to result from a combination of chronic, mild trauma which permit frictional irritation. A poor fitting denture never acquires papillomatosis. However, there must be some unidentified predisposing factors present in those patients who develop the lesion. It is also induced by low-grade infectio ...

Pityrosporum Folliculitis
Malassezia folliculitis or Pityrosporum folliculitis, is a skin condition caused by infection by ''Malassezia'' (formerly ''Pityrosporum'') yeast. The skin of the upper trunk area including the back, chest, arms and sometimes the neck is often affected and this condition is often seen in young to middle aged adults, although it has been known to occur in adults well into their sixties, and can also be found on the lower extremities as well. Its diagnosis is based on the pruritic (itchy) papulopustules found in a follicular pattern in these regions. Pustules are caused by an overgrowth of the yeast (a type of fungus) ''Malassezia furfur'' (''Pityrosporum ovale''), which plugs the follicles. ''M. furfur'' is lipophilic, requiring fatty acids like what is present in oily skin to proliferate. It has been shown that Malassezia yeast grows by consuming fatty acids with carbon chain lengths C11 to C24. Pityrosporum is part of the normal skin flora, but overgrows in certain conditions. O ...

Neural Fibrolipoma
Neural Fibrolipoma is an overgrowth of fibro-fatty tissue along a nerve trunk that often leads to nerve compression.James, William; Berger, Timothy; Elston, Dirk (2005). ''Andrews' Diseases of the Skin: Clinical Dermatology''. (10th ed.). Saunders. . These only occur in the extremities, and often affect the median nerve. They are rare, very slow-growing, and their origin is unknown. It is believed that they may begin growth in response to trauma. They are not encapsulated by any sort of covering or sheath around the growth itself, as opposed to other cysts beneath the skin that often are. This means there are loosely defined margins of this lipoma. Despite this, they are known to be benign. Neural fibrolipomas are often more firm and tough to the touch than other lipomas. They are slightly mobile under the skin, and compress with pressure. Diagnosis Neural fibrolipomas are often characterized by a mass under the skin accompanied with sensory deficit in the same area or a painful s ...

Congenital Hypertrophy Of The Lateral Fold Of The Hallux
Congenital hypertrophy of the lateral fold of the hallux is a rare cutaneous condition of unknown pathology that present to newborns. The condition was "first described by Martinet et al. in 1984." This sometimes painful condition involves "an overgrowth of the soft tissue" that can partially cover the nail plate. The condition usually effects both extremities and the condition can later reverse spontaneously. See also * List of cutaneous conditions Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against t ... References Cutaneous congenital anomalies Conditions of the skin appendages {{Cutaneous-condition-stub ...
