- Hydatidiform mole is a benign tumor of the placenta that has malignant potential. It is more common in Asian women and those over 35.
- Complete moles are diploid and paternal in origin, while partial moles are triploid with both paternal and maternal chromosomes. Complete moles have no fetus while partial moles may have an abnormal fetus.
- Diagnosis is made through ultrasound showing cystic spaces and very high HCG levels. Management involves surgical evacuation followed by monitoring of HCG levels to detect malignant changes, as 20% of complete moles may develop into gestational trophoblastic neoplasia.
This document summarizes the key mediators involved in the inflammatory response. It discusses how chemical mediators called cytokines, chemokines, lipids like prostaglandins and leukotrienes, amines such as histamine, peptides, complement proteins, and nitric oxide are released from cells to coordinate and regulate inflammation. These mediators act through receptors on target cells to produce effects like increased vascular permeability, leukocyte migration, pain, and fever responses. The document also outlines the innate and acquired immune responses mediated by cells like phagocytes, natural killer cells, and antibodies.

This document discusses Mullerian anomalies/defects, which range from agenesis to duplication of the tubes, uterus, cervix and upper vagina. It covers the classification system used (AFS), incidence, etiology, genetics, embryogenesis, clinical features, diagnosis using imaging modalies like HSG, USG and MRI, and management of various anomalies like unicornuate uterus, didelphys, bicornuate, septate and arcuate uterus. Complications in reproduction from each anomaly and outcomes of treatments like metroplasty are also summarized. Diethylstilbestrol exposure related abnormalities are briefly discussed.
Toxoplasma gondii is a coccidian parasite transmitted through contact with infected cat feces or consumption of undercooked meat. It typically causes mild or asymptomatic infections but can cause severe brain and eye damage in fetuses, infants, and immunocompromised individuals. Strongyloides stercoralis is a nematode transmitted through skin contact with soil. It resides in the small intestine and can cause chronic diarrhea but also disseminate and cause potentially fatal infections in malnourished or immunosuppressed individuals. Both parasites are diagnosed through examination of infected tissues and confirmed with serological tests.
The jugular venous pulse reflects right atrial pressure and is best examined in the right internal jugular vein. It normally displays three positive waves and two negative troughs related to atrial filling and emptying. Abnormalities can indicate conditions that elevate or lower right atrial pressure such as heart failure, tamponade, constriction. Specific wave changes suggest problems like tricuspid regurgitation or stenosis. The jugular venous pulse is a useful physical exam finding for cardiovascular assessment.
Heart murmurs can be produced by turbulence in blood flow caused by abnormalities in heart valves or structures. A murmur is described by its timing in the cardiac cycle, location, intensity, quality, and radiation pattern.
A mid-systolic murmur is the most common murmur and can be caused by ventricular outflow obstructions like aortic stenosis, dilation of the aorta/pulmonary trunk, accelerated flow, or innocent murmurs from normal anatomical variations. Diastolic murmurs include early diastolic murmurs like aortic regurgitation and high-pressure pulmonary regurgitation, and mid-diastolic murmurs caused by stenosis of the mitral or tricuspid valves. Flow murmurs
The document describes the development of the male and female reproductive systems from the indifferent stage through sexual differentiation. It covers the development of the gonads (testes and ovaries), genital ducts, and external genitalia. Some key points include:
- The gonads initially develop as indifferent gonads before differentiating into testes or ovaries depending on the presence of the SRY gene on the Y chromosome.
- The genital ducts also initially develop in an indifferent stage before the mesonephric ducts develop into male structures like the epididymis and vas deferens, while the paramesonephric ducts develop into female structures like the uterus and fallopian tubes.
- External
This document discusses chronic osteomyelitis, including its causes, pathology, presentations, examinations, investigations, differential diagnoses, and treatments. It can develop following acute osteomyelitis or be caused by tuberculosis or fungi. Pathology involves spread of pus within bone leading to bone death and cavities. Presentations include discharging sinuses and bone fragments. Investigations include x-rays showing bone changes and cultures of pus. Surgical treatments aim to remove dead bone and tissue. Complications include exacerbations, growth abnormalities, and fractures. It also discusses Garre's osteomyelitis and Brodie's abscess as specific types.
Forceps delivery is an operative vaginal delivery procedure that uses obstetric forceps to assist in the extraction of the fetal head. Forceps have curved blades that fit around the fetal head to allow the operator to apply gentle traction. Forceps delivery is indicated when there are signs of fetal distress, prolonged second stage of labor, or maternal medical complications. Risks include laceration, hemorrhage, and injuries to the mother or baby. Proper technique and only performing the procedure when fully trained can help minimize risks.
This document provides information on face presentation during childbirth. It defines face presentation as a cephalic presentation with the fetus in a complete extended attitude and the presenting part being the face. The two types of face presentation are primary (presenting before labor) and secondary (caused by extension during labor). The main positions are left and right mentoanterior and mentoposterior. Face presentation has a higher risk of complications compared to vertex presentation such as prolonged labor and increased need for operative delivery. The management involves allowing labor to progress for mentoanterior positions but cesarean section is usually needed for persistent mentoposterior.
E. coli is a normal flora in the gut but can cause several infections. It is the most common cause of urinary tract infections and can lead to different types of gastroenteritis depending on the strain. Some strains like EHEC O157:H7 can cause hemorrhagic colitis and potentially fatal hemolytic uremic syndrome in young children and the elderly. E. coli is also known to cause neonatal meningitis, wound infections after surgeries, and sepsis.
The brain receives a high blood supply to meet its metabolic demands. Arterial blood reaches the brain through the internal carotid and vertebral arteries, forming the circle of Willis at the base of the brain before branching into smaller vessels. Venous blood drains from the brain into internal jugular veins. Disruption of blood flow to the brain through cerebrovascular accidents like stroke can cause rapid loss of consciousness or permanent brain damage. Cerebrospinal fluid produced by choroid plexuses circulates within ventricles and around the brain and spinal cord, carrying nutrients and waste products.
This document discusses genetic diseases and abnormal fetal development. It begins with definitions of genetic terms like genetic code, chromosomes, genes, and cell division. It then discusses abnormal fetal development including malformations, deformations, and disruptions caused by chromosomal abnormalities, genetic defects, and environmental factors. The document ends by covering perinatal pathology including birth defects and metabolic disorders.
This document provides information on thalassemia, a group of genetic disorders that result in reduced hemoglobin production and anemia. It discusses the different types of thalassemia including alpha and beta thalassemia. Alpha thalassemia is caused by genetic deletions of the alpha globin genes and has varying severity from silent carrier to Hemoglobin H Disease to Bart's Hydrops Fetalis Syndrome. Beta thalassemia results from mutations in the beta globin genes and includes forms ranging from silent carrier to beta thalassemia minor to intermedia to major. Laboratory tests outlined can help diagnose and differentiate types of thalassemia based on red blood cell morphology, hemoglobin analysis and iron studies.
This document provides an overview of localizing neurological lesions, including definitions of key terms like the central nervous system and peripheral nervous system. It describes various motor and sensory pathways in the brain and spinal cord. Conditions covered include the corticospinal system, stroke syndromes, multiple sclerosis, cerebellar syndrome, and motor neuron disease. For each, the causes, signs, investigations, and management are summarized. Clinical case scenarios are also provided to help localize neurological lesions.
The document discusses motor units, muscle physiology, and locomotion. It can be summarized as:
1) A motor unit consists of a motoneuron and the muscle fibers it innervates, ranging from a few to thousands of fibers. Smaller motor units allow more refined control.
2) Muscle contraction occurs when an action potential in the motoneuron causes acetylcholine release and muscle fiber depolarization, activating calcium release and cross-bridge cycling to generate force.
3) Locomotion involves complex coordination of many joints and muscles, which is controlled centrally by pattern generators in the spinal cord rather than individually at the muscle level.
The document summarizes somatic sensory and motor pathways in the human body. It describes two main somatic sensory pathways - the posterior column pathway and anterolateral pathway - which carry different sensory signals from receptors to the cortex via three neurons. It also outlines the direct corticospinal and corticobulbar motor pathways that transmit signals from the motor cortex to skeletal muscles and cranial nerve motor nuclei respectively, to initiate voluntary movement.
Thalassemia and hemoglobinopathies are blood disorders characterized by decreased or abnormal hemoglobin production. Thalassemias result from reduced or absent globin chain synthesis, causing an imbalance between globin chains. Hemoglobinopathies involve the synthesis of abnormal hemoglobin variants. The most common thalassemias are alpha and beta thalassemia. Alpha thalassemia is caused by deletions of alpha globin genes and ranges from asymptomatic to hydrops fetalis. Beta thalassemia results from mutations that decrease beta chain production, leading to excess unpaired alpha chains and hemolysis. Clinical severity depends on degree of beta chain reduction.
Leprosy is caused by Mycobacterium leprosy, an acid-fast bacillus. It has a long incubation period of 2-5 years and optimal growth temperature of 30 degrees Celsius. Men are affected more than women at a ratio of 2:1. Key signs include hypoesthetic or anesthetic skin lesions and thickened peripheral nerves. Leprosy is classified based on infectivity and treatment response. The Ridley-Jopling classification categorizes cases as tuberculoid (TT), borderline tuberculoid (BT), borderline borderline (BB), borderline lepromatous (BL) or lepromatous (LL) based on skin and nerve involvement. Dif
There are several ascending pathways that transmit sensory information from the spinal cord to the brain. The three-neuron pathway involves primary sensory neurons that enter the spinal cord and synapse on secondary neurons whose axons form tracts in the spinal cord and brainstem. Tertiary neurons project from the thalamus to the primary sensory cortex. The spinothalamic and medial lemniscal systems transmit information for conscious perception, while the spinocerebellar, spino-olivary, spinotectal, and spinoreticular systems are involved in unconscious perception. The lateral and anterior spinothalamic tracts carry different sensory modalities from the spinal cord to the thalamus and on to the sensory cortex.
Gestational diabetes mellitus (GDM) is glucose intolerance that begins or is first recognized during pregnancy. The prevalence of GDM is increasing globally. Risk factors include family history of diabetes, obesity, older age, and certain ethnic backgrounds. GDM increases risks for both mother and fetus, including preeclampsia, macrosomia, and neonatal complications. Screening involves a 50g glucose challenge test between 24-28 weeks, followed by a 100g oral glucose tolerance test for those who fail. Treatment focuses on medical nutrition therapy, blood glucose monitoring, and may include insulin to achieve targeted glucose levels and prevent complications.
This document summarizes congenital malformations of the female genital tract. It describes disorders including Mayer-Rokitansky-Kuster-Hauser syndrome which is characterized by the absence of the upper vagina, cervix and uterus. It also discusses disorders of lateral fusion of the mullerian ducts which can result in abnormalities such as a uterus didelphys, bicornuate uterus or septate uterus. These abnormalities are associated with increased risks in pregnancy such as recurrent abortions or premature birth. The document outlines approaches to diagnosis and treatment of various mullerian duct anomalies.

PGx Analysis in VarSeq: A User’s PerspectiveGolden Helix
Since our release of the PGx capabilities in VarSeq, we’ve had a few months to gather some insights from various use cases. Some users approach PGx workflows by means of array genotyping or what seems to be a growing trend of adding the star allele calling to the existing NGS pipeline for whole genome data. Luckily, both approaches are supported with the VarSeq software platform. The genotyping method being used will also dictate what the scope of the tertiary analysis will be. For example, are your PGx reports a standalone pipeline or would your lab’s goal be to handle a dual-purpose workflow and report on PGx + Diagnostic findings.
The purpose of this webcast is to:
Discuss and demonstrate the approaches with array and NGS genotyping methods for star allele calling to prep for downstream analysis.
Following genotyping, explore alternative tertiary workflow concepts in VarSeq to handle PGx reporting.
Moreover, we will include insights users will need to consider when validating their PGx workflow for all possible star alleles and options you have for automating your PGx analysis for large number of samples. Please join us for a session dedicated to the application of star allele genotyping and subsequent PGx workflows in our VarSeq software.

GASTROINTESTINAL INFECTIONS AND GASTRITIS
Osvaldo Bernardo Muchanga
Gastrointestinal Infections
GASTROINTESTINAL INFECTIONS result from the ingestion of pathogens that cause infections at the level of this tract, generally being transmitted by food, water and hands contaminated by microorganisms such as E. coli, Salmonella, Shigella, Vibrio cholerae, Campylobacter, Staphylococcus, Rotavirus among others that are generally contained in feces, thus configuring a FECAL-ORAL type of transmission.
Among the factors that lead to the occurrence of gastrointestinal infections are the hygienic and sanitary deficiencies that characterize our markets and other places where raw or cooked food is sold, poor environmental sanitation in communities, deficiencies in water treatment (or in the process of its plumbing), risky hygienic-sanitary habits (not washing hands after major and/or minor needs), among others.
These are generally consequences (signs and symptoms) resulting from gastrointestinal infections: diarrhea, vomiting, fever and malaise, among others.
The treatment consists of replacing lost liquids and electrolytes (drinking drinking water and other recommended liquids, including consumption of juicy fruits such as papayas, apples, pears, among others that contain water in their composition).
To prevent this, it is necessary to promote health education, improve the hygienic-sanitary conditions of markets and communities in general as a way of promoting, preserving and prolonging PUBLIC HEALTH.
Gastritis and Gastric Health
Gastric Health is one of the most relevant concerns in human health, with gastrointestinal infections being among the main illnesses that affect humans.
Among gastric problems, we have GASTRITIS AND GASTRIC ULCERS as the main public health problems. Gastritis and gastric ulcers normally result from inflammation and corrosion of the walls of the stomach (gastric mucosa) and are generally associated (caused) by the bacterium Helicobacter pylor, which, according to the literature, this bacterium settles on these walls (of the stomach) and starts to release urease that ends up altering the normal pH of the stomach (acid), which leads to inflammation and corrosion of the mucous membranes and consequent gastritis or ulcers, respectively.
In addition to bacterial infections, gastritis and gastric ulcers are associated with several factors, with emphasis on prolonged fasting, chemical substances including drugs, alcohol, foods with strong seasonings including chilli, which ends up causing inflammation of the stomach walls and/or corrosion. of the same, resulting in the appearance of wounds and consequent gastritis or ulcers, respectively.
Among patients with gastritis and/or ulcers, one of the dilemmas is associated with the foods to consume in order to minimize the sensation of pain and discomfort.
Are you looking for a long-lasting solution to your missing tooth?
Dental implants are the most common type of method for replacing the missing tooth. Unlike dentures or bridges, implants are surgically placed in the jawbone. In layman’s terms, a dental implant is similar to the natural root of the tooth. It offers a stable foundation for the artificial tooth giving it the look, feel, and function similar to the natural tooth.
The skin is the largest organ and its health plays a vital role among the other sense organs. The skin concerns like acne breakout, psoriasis, or anything similar along the lines, finding a qualified and experienced dermatologist becomes paramount.
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.
