Narrowing of the pyloric canal with varied etiology. A common form is due to muscle hypertrophy (PYLORIC STENOSIS, HYPERTROPHIC) seen in infants.
Narrowing of the pyloric canal due to HYPERTROPHY of the surrounding circular muscle. It is usually seen in infants or young children.
The region of the STOMACH at the junction with the DUODENUM. It is marked by the thickening of circular muscle layers forming the pyloric sphincter to control the opening and closure of the lumen.
General increase in bulk of a part or organ due to CELL ENLARGEMENT and accumulation of FLUIDS AND SECRETIONS, not due to tumor formation, nor to an increase in the number of cells (HYPERPLASIA).
The region between the sharp indentation at the lower third of the STOMACH (incisura angularis) and the junction of the PYLORUS with the DUODENUM. Pyloric antral glands contain mucus-secreting cells and gastrin-secreting endocrine cells (G CELLS).
The forcible expulsion of the contents of the STOMACH through the MOUTH.
An infant during the first month after birth.
The protrusion of an organ or part of an organ into a natural or artificial orifice.
A variety of surgical reconstructive procedures devised to restore gastrointestinal continuity, The two major classes of reconstruction are the Billroth I (gastroduodenostomy) and Billroth II (gastrojejunostomy) procedures.
Medical procedure involving the emptying of contents in the stomach through the use of a tube inserted through the nose or mouth. It is performed to remove poisons or relieve pressure due to intestinal blockages or during surgery.
An involuntary contraction of a muscle or group of muscles. Spasms may involve SKELETAL MUSCLE or SMOOTH MUSCLE.
Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX). (From Adams et al., Principles of Neurology, 6th ed, pp 822-3)
The sequence in which children are born into the family.
A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
Pathological processes involving the STOMACH.
The evacuation of food from the stomach into the duodenum.
A semi-synthetic macrolide antibiotic structurally related to ERYTHROMYCIN. It has been used in the treatment of Mycobacterium avium intracellulare infections, toxoplasmosis, and cryptosporidiosis.
A bacteriostatic antibiotic macrolide produced by Streptomyces erythreus. Erythromycin A is considered its major active component. In sensitive organisms, it inhibits protein synthesis by binding to 50S ribosomal subunits. This binding process inhibits peptidyl transferase activity and interferes with translocation of amino acids during translation and assembly of proteins.

Functional intestinal obstruction due to deficiency of argyrophil neurones in the myenteric plexus. Familial syndrome presenting with short small bowel, malrotation, and pyloric hypertrophy. (1/118)

In 3 infants functional intestinal obstruction, associated with a short small intestine, malrotation, and pyloric hypertrophy, was shown to be due to failure of development of the argyrophil myenteric plexus, with the absence of ongoing peristalsis. 4 infants with similar clinical features have been described previously, and there is evidence for an autosomal recessive mode of inheritance of this syndrome.  (+info)

Pyloric stenosis in the Oxford Record Linkage Study area. (2/118)

The files of the Oxford Record Linkage Study were employed to identify 220 infants presenting with infantile hypertrophic pyloric stenosis (IHPS) in the 6-year period 1966 to 1971. Information on these infants was obtained from birth certificates and maternity notes. The overall incidence was 2.5 per 1000 livebirths. There was a distinct seasonal variation, with highest incidence to infants born in the third quarter of the year as well as variation in incidence with area: the cities had much lower rates of IHPS than the adjacent rural or small urban areas. It was shown that the rates in the south and east of the area studied were far greater than in the north and west. In the present study there was no excess of primiparae, the peak maternal age group was 20 to 24; there was a slight excess of parents of social classes I and II; and a significant association with mothers who were Rhesus negative. The rate of IHPS among sibs was 85 per 1000. Though there was the usual correlation with the male sex (M:F ratio = 5.5:1), there was no variation with birthweight and only among the females was an association found with prolonged gestation. There appeared to be an inverse relation between gestation and age on admission to hospital.  (+info)

Simultaneous pyloric and colonic obstruction associated with hiatus hernia in a weightlifter: a case report. (3/118)

Hiatus hernia is usually attributed to conditions that cause a chronic increase in intra-abdominal pressure such as multiple pregnancies and obesity. A 30-year-old man, a weightlifter, had a massive hiatus hernia causing both high and low gastrointestinal obstruction but no involvement of the gastroesophageal junction or fundus. The onset of the obstruction is attributed to an extreme increase in intra-abdominal pressure caused by the action of lifting weights.  (+info)

Jaundice with hypertrophic pyloric stenosis as an early manifestation of Gilbert syndrome. (4/118)

Jaundice associated with hypertrophic pyloric stenosis was recognised in three patients; previous reports have suggested that this is a possible early manifestation of Gilbert syndrome. Most patients with Gilbert syndrome are homozygous for a (TA)(7)TAA polymorphism in the gene promoter coding for bilirubin glucuronosyltransferase. Two of the reported patients were homozygous for the (TA)(7)TAA polymorphism whereas the third was heterozygous for the same polymorphism. Furthermore, no other factors contributing to jaundice in the three patients were found. These results suggest that jaundice associated with hypertrophic pyloric stenosis is due to molecular defects within the gene promoter.  (+info)

Pyloric ratio: efficacy in the diagnosis of hypertrophic pyloric stenosis. (5/118)

We sought to define a weight independent, highly sensitive and specific measurement to diagnose hypertrophic pyloric stenosis. A retrospective review of 87 children was performed. We determined the pyloric ratio (wall thickness/pyloric diameter) and its relationship to weight and compared it to standard criteria. The average pyloric ratios in normal children and in those with hypertrophic pyloric stenosis were 0.205 and 0.325, respectively (P < 0.001). A pyloric ratio of 0.27 yielded a sensitivity and specificity of 96% and 94%, respectively. The pyloric ratio maintained a linear relationship to weight in normal patients and those with hypertrophic pyloric stenosis. We conclude the pyloric ratio can be a highly sensitive, specific, and weight independent indicator of hypertrophic pyloric stenosis.  (+info)

Hypertrophic pyloric stenosis in infants following pertussis prophylaxis with erythromycin--Knoxville, Tennessee, 1999. (6/118)

In February 1999, pertussis was diagnosed in six neonates born at hospital A in Knoxville, Tennessee. Because a health-care worker at hospital A was most likely the source of exposure, the local health department recommended on February 25, 1999, that erythromycin be prescribed as postexposure prophylaxis for the approximately 200 infants born at hospital A during February 1-24, 1999. In March 1999, local pediatric surgeons noticed an increased number of cases of infantile hypertrophic pyloric stenosis (IHPS) in the area, with seven cases occurring during a 2-week period. All seven IHPS cases were in infants born in hospital A during February who were given erythromycin orally for prophylaxis following possible exposure to pertussis, although none had pertussis diagnosed. The Tennessee Department of Health and CDC investigated the cluster of IHPS cases and its possible association with use of erythromycin. This report summarizes the results of the investigation, which suggest a causal role of erythromycin in this cluster of IHPS cases.  (+info)

Molecular cytogenetic characterisation of partial trisomy 9q in a case with pyloric stenosis and a review. (7/118)

Partial trisomy 9q represents a rare and heterogeneous group of chromosomal aberrations characterised by various clinical features including pyloric stenosis. Here, we describe the case of a 1 year old female patient with different dysmorphic features including pyloric stenosis and prenatally detected partial trisomy 9q. This partial trisomy 9q has been analysed in detail to determine the size of the duplication and to characterise the chromosomal breakpoints. According to the data gained by different molecular cytogenetic techniques, such as fluorescence in situ hybridisation (FISH) with whole and partial chromosome painting probes, yeast artificial chromosome (YAC) probes, and comparative genomic hybridisation (CGH), the derivative chromosome 9 can be described as dup(9)(pter-->q22. 1::q31.1-->q22.1::q31.1--> q22.1::q31.1-->qter). Four breakpoint spanning YACs have been identified (y806f02, y906g6, y945f5, and y747b3) for the proximal breakpoint. According to this new case and previously published data, the recently postulated putative critical region for pyloric stenosis can be narrowed down to the subbands 9q22.1-q31.1 and is the result of either partial trisomy of gene(s) located in this region or a gene disrupted in 9q31.  (+info)

Laparoscopic pyloroplasty in idiopathic hypertrophic pyloric stenosis in an adult. (8/118)

BACKGROUND AND OBJECTIVES: Idiopathic hypertrophic pyloric stenosis, in adults, is a rare disease. Partial gastrectomy, gastroenterostomy, pyloromyotomy, pyloroplasty and endoscopic dilatation have all been recommended with variable results. A 54-year-old white female is presented with the onset of symptoms of idiopathic hypertrophic pyloric stenosis one year prior to operation. Two endoscopic pyloric sphincter balloon dilatations provided only temporary relief. METHOD: A laparoscopic pyloroplasty was performed. RESULT: The patient tolerated a solid diet on postoperative day three. The patient was symptom-free at a 13 month follow-up. CONCLUSIONS: Idiopathic hypertrophic pyloric stenosis in adults can be treated with laparoscopic pyloroplasty, offering a minimally invasive alternative to open repair.  (+info)

Pyloric stenosis is a condition that results in the narrowing or complete obstruction of the pylorus, which is the opening from the stomach into the small intestine. This narrowing is usually caused by hypertrophy (thickening) of the muscles in the pylorus, making it difficult for food to pass from the stomach into the duodenum.

The most common form of this condition is infantile hypertrophic pyloric stenosis, which typically affects infants between 3-6 weeks of age. In this case, the pyloric muscle becomes abnormally thick and narrows the opening, making it difficult for stomach contents to empty into the small intestine. This can lead to symptoms such as vomiting (often projectile), dehydration, and poor weight gain.

The diagnosis of pyloric stenosis is often made through physical examination, ultrasound, or other imaging studies. Treatment typically involves surgery to correct the narrowed opening, known as a pyloromyotomy. This procedure involves making an incision in the pylorus to relieve the obstruction and allow normal stomach emptying.

In some cases, pyloric stenosis can also occur in adults, although this is much less common than in infants. Adult pyloric stenosis can be caused by various factors, including chronic gastritis, peptic ulcers, or previous surgeries. The symptoms and treatment approach for adult pyloric stenosis may differ from those seen in infants.

Hypertrophic pyloric stenosis is a condition that affects the muscular valve between the stomach and the small intestine (pylorus). It is characterized by an abnormal thickening (hypertrophy) of the pylorus muscle, which can cause narrowing (stenosis) of the pyloric canal. This makes it difficult for food to pass from the stomach into the small intestine, leading to symptoms such as vomiting, dehydration, and poor weight gain in infants. The condition is typically diagnosed through physical examination, medical history, and imaging tests like ultrasound or X-rays. Treatment usually involves surgery to correct the narrowed pylorus and alleviate symptoms.

The pylorus is the lower, narrow part of the stomach that connects to the first part of the small intestine (duodenum). It consists of the pyloric canal, which is a short muscular tube, and the pyloric sphincter, a circular muscle that controls the passage of food from the stomach into the duodenum. The pylorus regulates the entry of chyme (partially digested food) into the small intestine by adjusting the size and frequency of the muscular contractions that push the chyme through the pyloric sphincter. This process helps in further digestion and absorption of nutrients in the small intestine.

Hypertrophy, in the context of physiology and pathology, refers to an increase in the size of an organ or tissue due to an enlargement of its constituent cells. It is often used to describe the growth of muscle cells (myocytes) in response to increased workload or hormonal stimulation, resulting in an increase in muscle mass. However, hypertrophy can also occur in other organs such as the heart (cardiac hypertrophy) in response to high blood pressure or valvular heart disease.

It is important to note that while hypertrophy involves an increase in cell size, hyperplasia refers to an increase in cell number. In some cases, both hypertrophy and hyperplasia can occur together, leading to a significant increase in the overall size and function of the organ or tissue.

The pyloric antrum is the distal part of the stomach, which is the last portion that precedes the pylorus and the beginning of the duodenum. It is a thickened, muscular area responsible for grinding and mixing food with gastric juices during digestion. The pyloric antrum also helps regulate the passage of chyme (partially digested food) into the small intestine through the pyloric sphincter, which controls the opening and closing of the pylorus. This region is crucial in the gastrointestinal tract's motor functions and overall digestive process.

Vomiting is defined in medical terms as the forceful expulsion of stomach contents through the mouth. It is a violent, involuntary act that is usually accompanied by strong contractions of the abdominal muscles and retching. The body's vomiting reflex is typically triggered when the brain receives signals from the digestive system that something is amiss.

There are many potential causes of vomiting, including gastrointestinal infections, food poisoning, motion sickness, pregnancy, alcohol consumption, and certain medications or medical conditions. In some cases, vomiting can be a symptom of a more serious underlying condition, such as a brain injury, concussion, or chemical imbalance in the body.

Vomiting is generally not considered a serious medical emergency on its own, but it can lead to dehydration and other complications if left untreated. If vomiting persists for an extended period of time, or if it is accompanied by other concerning symptoms such as severe abdominal pain, fever, or difficulty breathing, it is important to seek medical attention promptly.

A newborn infant is a baby who is within the first 28 days of life. This period is also referred to as the neonatal period. Newborns require specialized care and attention due to their immature bodily systems and increased vulnerability to various health issues. They are closely monitored for signs of well-being, growth, and development during this critical time.

A prolapse is a medical condition where an organ or tissue in the body slips from its normal position and drops down into a lower part of the body. This usually occurs when the muscles and ligaments that support the organ become weak or stretched. The most common types of prolapses include:

* Uterine prolapse: When the uterus slips down into or protrudes out of the vagina.
* Rectal prolapse: When the rectum (the lower end of the colon) slips outside the anus.
* Bladder prolapse (cystocele): When the bladder drops into the vagina.
* Small bowel prolapse (enterocele): When the small intestine bulges into the vagina.

Prolapses can cause various symptoms, such as discomfort, pain, pressure, and difficulty with urination or bowel movements. Treatment options depend on the severity of the prolapse and may include lifestyle changes, physical therapy, medication, or surgery.

Gastroenterostomy is a surgical procedure that creates an anastomosis (a connection or junction) between the stomach and the small intestine, usually between the stomach's lesser curvature and the jejunum (the second part of the small intestine). This procedure is often performed to bypass a diseased or obstructed portion of the gastrointestinal tract, such as in the case of gastric ulcers, tumors, or other conditions that prevent normal digestion and absorption.

There are different types of gastroenterostomy procedures, including:
1. Billroth I (or "gastroduodenostomy"): The stomach is connected directly to the duodenum (the first part of the small intestine).
2. Billroth II (or "gastrojejunostomy"): The stomach is connected to the jejunum, bypassing the duodenum.
3. Roux-en-Y gastrojejunostomy: A more complex procedure in which a portion of the jejunum is separated and reconnected further down the small intestine, creating a Y-shaped configuration. This type of gastroenterostomy is often used in bariatric surgery for weight loss.

The choice of gastroenterostomy technique depends on the specific medical condition being treated and the patient's overall health status.

Gastric lavage, also known as stomach pumping, is a medical procedure where the stomach's contents are emptied using a tube that is inserted through the mouth or nose and into the stomach. The tube is then connected to suction, which helps remove the stomach contents. This procedure is often used in emergency situations to treat poisonings or overdoses by removing the toxic substance before it gets absorbed into the bloodstream. It can also be used to empty the stomach before certain surgeries or procedures.

A spasm is a sudden, involuntary contraction or tightening of a muscle, group of muscles, or a hollow organ such as the ureter or bronchi. Spasms can occur as a result of various factors including muscle fatigue, injury, irritation, or abnormal nerve activity. They can cause pain and discomfort, and in some cases, interfere with normal bodily functions. For example, a spasm in the bronchi can cause difficulty breathing, while a spasm in the ureter can cause severe pain and may lead to a kidney stone blockage. The treatment for spasms depends on the underlying cause and may include medication, physical therapy, or lifestyle changes.

Carotid stenosis is a medical condition that refers to the narrowing or constriction of the lumen (inner space) of the carotid artery. The carotid arteries are major blood vessels that supply oxygenated blood to the head and neck. Carotid stenosis usually results from the buildup of plaque, made up of fat, cholesterol, calcium, and other substances, on the inner walls of the artery. This process is called atherosclerosis.

As the plaque accumulates, it causes the artery to narrow, reducing blood flow to the brain. Severe carotid stenosis can increase the risk of stroke, as a clot or debris from the plaque can break off and travel to the brain, blocking a smaller blood vessel and causing tissue damage or death.

Carotid stenosis is typically diagnosed through imaging tests such as ultrasound, CT angiography, or MRI angiography. Treatment options may include lifestyle modifications (such as quitting smoking, controlling blood pressure, and managing cholesterol levels), medications to reduce the risk of clots, or surgical procedures like endarterectomy or stenting to remove or bypass the blockage.

Birth order is a term that refers to the sequence in which a person is born in their family, specifically in relation to their siblings. It is used in psychology and sociology to describe the various personality traits, behaviors, and developmental milestones that have been associated with being the firstborn, middle child, youngest child, or an only child.

For example, some studies suggest that firstborn children tend to be more responsible, achievement-oriented, and socially dominant than their younger siblings, while later-born children may be more easygoing, adventurous, and rebellious. However, it's important to note that these patterns are not universal and can be influenced by a variety of factors, including family size, spacing between siblings, gender, parenting style, and individual temperament.

Overall, birth order is just one factor among many that contribute to a person's development and identity, and should not be used as a definitive predictor of their traits or behaviors.

Aortic valve stenosis is a cardiac condition characterized by the narrowing or stiffening of the aortic valve, which separates the left ventricle (the heart's main pumping chamber) from the aorta (the large artery that carries oxygen-rich blood to the rest of the body). This narrowing or stiffening prevents the aortic valve from opening fully, resulting in reduced blood flow from the left ventricle to the aorta and the rest of the body.

The narrowing can be caused by several factors, including congenital heart defects, calcification (hardening) of the aortic valve due to aging, or scarring of the valve due to rheumatic fever or other inflammatory conditions. As a result, the left ventricle must work harder to pump blood through the narrowed valve, which can lead to thickening and enlargement of the left ventricular muscle (left ventricular hypertrophy).

Symptoms of aortic valve stenosis may include chest pain or tightness, shortness of breath, fatigue, dizziness or fainting, and heart palpitations. Severe aortic valve stenosis can lead to serious complications such as heart failure, arrhythmias, or even sudden cardiac death. Treatment options may include medications to manage symptoms, lifestyle changes, or surgical intervention such as aortic valve replacement.

Stomach diseases refer to a range of conditions that affect the stomach, a muscular sac located in the upper part of the abdomen and is responsible for storing and digesting food. These diseases can cause various symptoms such as abdominal pain, nausea, vomiting, heartburn, indigestion, loss of appetite, and bloating. Some common stomach diseases include:

1. Gastritis: Inflammation of the stomach lining that can cause pain, irritation, and ulcers.
2. Gastroesophageal reflux disease (GERD): A condition where stomach acid flows back into the esophagus, causing heartburn and damage to the esophageal lining.
3. Peptic ulcers: Open sores that develop on the lining of the stomach or duodenum, often caused by bacterial infections or long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs).
4. Stomach cancer: Abnormal growth of cancerous cells in the stomach, which can spread to other parts of the body if left untreated.
5. Gastroparesis: A condition where the stomach muscles are weakened or paralyzed, leading to difficulty digesting food and emptying the stomach.
6. Functional dyspepsia: A chronic disorder characterized by symptoms such as pain, bloating, and fullness in the upper abdomen, without any identifiable cause.
7. Eosinophilic esophagitis: A condition where eosinophils, a type of white blood cell, accumulate in the esophagus, causing inflammation and difficulty swallowing.
8. Stomal stenosis: Narrowing of the opening between the stomach and small intestine, often caused by scar tissue or surgical complications.
9. Hiatal hernia: A condition where a portion of the stomach protrudes through the diaphragm into the chest cavity, causing symptoms such as heartburn and difficulty swallowing.

These are just a few examples of stomach diseases, and there are many other conditions that can affect the stomach. Proper diagnosis and treatment are essential for managing these conditions and preventing complications.

Gastric emptying is the process by which the stomach empties its contents into the small intestine. In medical terms, it refers to the rate and amount of food that leaves the stomach and enters the duodenum, which is the first part of the small intestine. This process is regulated by several factors, including the volume and composition of the meal, hormonal signals, and neural mechanisms. Abnormalities in gastric emptying can lead to various gastrointestinal symptoms and disorders, such as gastroparesis, where the stomach's ability to empty food is delayed.

Azithromycin is a widely used antibiotic drug that belongs to the class of macrolides. It works by inhibiting bacterial protein synthesis, which leads to the death of susceptible bacteria. This medication is active against a broad range of gram-positive and gram-negative bacteria, atypical bacteria, and some parasites.

Azithromycin is commonly prescribed to treat various bacterial infections, such as:

1. Respiratory tract infections, including pneumonia, bronchitis, and sinusitis
2. Skin and soft tissue infections
3. Sexually transmitted diseases, like chlamydia
4. Otitis media (middle ear infection)
5. Traveler's diarrhea

The drug is available in various forms, including tablets, capsules, suspension, and intravenous solutions. The typical dosage for adults ranges from 250 mg to 500 mg per day, depending on the type and severity of the infection being treated.

Like other antibiotics, azithromycin should be used judiciously to prevent antibiotic resistance. It is essential to complete the full course of treatment as prescribed by a healthcare professional, even if symptoms improve before finishing the medication.

Erythromycin is a type of antibiotic known as a macrolide, which is used to treat various types of bacterial infections. It works by inhibiting the bacteria's ability to produce proteins, which are necessary for the bacteria to survive and multiply. Erythromycin is often used to treat respiratory tract infections, skin infections, and sexually transmitted diseases. It may also be used to prevent endocarditis (inflammation of the lining of the heart) in people at risk of this condition.

Erythromycin is generally considered safe for most people, but it can cause side effects such as nausea, vomiting, and diarrhea. It may also interact with other medications, so it's important to tell your doctor about all the drugs you are taking before starting erythromycin.

Like all antibiotics, erythromycin should only be used to treat bacterial infections, as it is not effective against viral infections such as the common cold or flu. Overuse of antibiotics can lead to antibiotic resistance, which makes it harder to treat infections in the future.
