Microbiological evidence – positive blood cultures not meeting major criteria or serological evidence of infection What are the causes of culture-negative endocarditis? Poor culture techniques, sampling error – Cultures taken in abacteraemic phase Right-sided endocarditis How is infective endocarditis treated? The exact regimen and doses will be dictated by local microbiological guidelines and microbiology advice should be sought early. You may be asked to demonstrate this in the exam and you must be well prepared for this. Blood cultures are best taken when the patient spikes a fever (maximal bacteraemia). Introduce yourself to the patient, check patient’s identity, explain procedure, confirm indication and gain informed consent. Gather relevant equipment – Pair of culture bottles (aerobic and anaerobic), needle, 20 mL syringe, Vacutainer system, tourniquet, sterile gloves of appropriate size, alcohol wipe/Betadine etc. Clean the entrance ports of the blood culture bottles with an alcohol wipe and allow to dry for at least 30 seconds. Apply a tourniquet proximal to the elbow crease, and palpate for and select a vein. With a conventional needle/syringe, the anaerobic bottle is filled first to avoid introducing air into anaerobic bottle (N. If the winged butterfly needle technique is used, air is present in the line and therefore the aerobic bottle is best filled first. Although it used to be advised to change needles before filling the first bottle and between bottles in order to reduce the risk of contamination, this is no longer advised as it increases the risk of needle-stick injuries. Remove the tourniquet, apply pressure over the venepuncture site and withdraw the needle. Gain haemostasis from the venepuncture site by applying cotton wool until bleeding has stopped and dispose of all sharps safely in a sharps bin. Label the blood cultures with the patient’s details (name, date of birth and hospital number) and the date and time when the blood sample was taken. Try to gather three sets of blood cultures separated in time and space (especially for endocarditis) to improve the sensitivity. Start empirical antibiotics after cultures taken to avoid culture-negative (false negative) results. Important points: Blood cultures should be performed prior to commencing antibiotics. Each set of blood cultures consists of an anaerobic and aerobic blood culture bottle. A fever occurs between 30 and 120 minutes after the introduction of bacteria into the circulation. Ideally, three sets of blood cultures should be performed from at least two different sites. If a central line is in situ, blood cultures should be sent from blood taken from the line. Location – Near the Intensive Care, Accident and Emergency and Radiology Departments. Reduce solar heat gain or loss; the operating suites should be located in the lower hospital levels. Clean zone – Scrub rooms, gowning areas, exit lobby, rest areas and sterile stores Sterile zone – the operating theatre and sterile preparation rooms Disposal zone – the least clean area: Disposal sluice or sink rooms Hospital staff should move from one clean area to another without having to pass through unprotected or traffic areas. Heating, air-conditioning and ventilation should allow for comfortable working conditions. General lightening of theatres should be provided by fluorescent tubes or filament lamps producing illumination with little or no glaze. The main operating lights are compared by direct light from several angles to reduce shadows. Electricity should be maintained with emergency support (supplementary generator) in case of power failure. Joins between walls, ceiling and floors should be curved to reduce dirty collection. The colour of the operating suites should be pale-blue, grey or green in order to be less tiring on the eyes. The main goals of ventilation are as follows: Comfort to all hospital staff Removal of anaesthetic gas Admit air that is free of pathological organisms What types of ventilation are used in operating rooms? The aim of the airflow system is to prevent airborne microorganisms entering the surgical wound. Ventilation should allow air to pass through a steam humidifier, resulting in 50%–60% relative humidity. Combined with background heating, the ventilation system can be used to adjust the temperature in the operating suites to between 18. After filteration, air is introduced at ceiling height and exhausted near the floor with at least 20 air changes per hour. The operating theatre is maintained at a positive pressure relative to the surroundings. Turbulent air flow system Positive pressure is used to prevent dirty air entering the sterile operating suites. Laminar flow displacement system the high impact and high exhaust system was first introduced by Charnley. Airflow moves at a unidirectional horizontal velocity and passes through filters to remove contamination. Laminar airflow provides 100- 300 air changes per hour and is used in cases involving insertion of implants (e. A surgeon must always make patient safety and well-being their number one priority. This not only applies within the operating theatre, but also before and after any operation, when the patient is just as vulnerable. As medical students, we are always taught the old aphorism ‘primum non nocere’ (which as you may recall means ‘first do no harm’) and you must never forget this, as you advance and progress in your chosen specialty. Ultimately, the surgeon is responsible for any patient that is under his or her care. Adequate preventative measures should always be put in place to ensure that the risks posed to hospital patients are kept to an absolute minimum.

They are first synthesized as a signal peptide called by modification of their side chains, hydroxylation preprohormone, which is then cleaved to form pro- and ring aromatization at various sites. Amine Hormone Synthesis All amine hormones except serotonin are synthesized from the amino acid tyrosine that requires a series of enzymatic reactions. Catecho lamines are stored in granules and secreted by calcium mediated exocytosis of granules in which they are stored. Many enzymatic reactions are involved in the process of steroid hormone synthesis: 1. On stimulation, the hormones become free form intra is packaged in the secretory granules for storage cellular proteins and are transported outside the cell (Flowchart 52.

Endocrine gland senses biological activity of the regulation of endocrine functions. The endocrine cells that secrete the hormone also sense the biological activity produced by the hormone: 1. When the biological effects are more, the hormone secretion decreases appropriately to maintain normal function of the hormone (Flowchart 52.

Secretion of hormones in response to various stimuli Many hormones influence secretion of other hormones.

The anatomic basis of the anterior cutaneous nerve block is the fact that the innervation of the anterolateral abdominal wall is provided by the lower six intercostal nerves and the first lumbar nerve generic telmisartan 80 mg on line blood pressure chart to record. The anterior branches of these nerves pass within a fascial plane between the internal oblique muscle and the transversus abdominis muscle making them easily assessable for blockade with local anesthetic by placing a needle into this fascial plane (see Chapter 90) order 20 mg telmisartan with mastercard blood pressure medication propranolol. The anterior cutaneous branch then pierces the fascia of the abdominal wall at the lateral border of the rectus abdominis muscle (Fig purchase telmisartan 80 mg on line blood pressure 80 over 40. The nerve turns sharply in an anterior direction to provide innervation to the anterior wall (Fig telmisartan 20 mg on-line blood pressure medication upset stomach. The nerve passes through a firm fibrous ring as it pierces the fascia, and it is at this point that the nerve is subject to entrapment (Figs. Occasionally, the terminal branches of a given intercostal nerve may actually cross the midline to provide sensory innervation to the contralateral chest and abdominal wall. The anterior cutaneous nerve turns sharply in an anterior direction to provide innervation to the anterior wall. The nerve passes through a firm fibrous ring as it pierces the fascia and it is at this point that the nerve 673 is subject to entrapment. Photomicrograph of anterior cutaneous nerve entrapment, showing middle of fibrous ring, nerve (n) exiting in fatty plug (f. Microanatomy of the structures contributing to abdominal cutaneous nerve entrapment syndrome. The clinical presentation of this painful condition includes a constellation of symptoms including severe, knife-like anterior abdominal wall pain that is associated with point tenderness over the affected anterior cutaneous nerve. The pain of anterior cutaneous nerve entrapment syndrome radiates medially to the linea alba and rarely crossed the midline. This entrapment syndrome occurs most commonly in young females and is often attributed to ovarian pain or mittelschmerz. Often the patient can accurately localize the site of nerve entrapment which can be confirmed by the clinician by palpating the spot the patient identifies with a straightened index finger or cotton tipped applicator. If the patient confirms that the point being palpated is the nidus of the patient’s pain symptomatology, the patient is then asked to contract the abdominal muscles which should further exacerbate the pain if the cause if anterior cutaneous nerve entrapment. Carnett test is then performed by having the patient do a partial sit up with their head lifted completely off the table (Fig. This test will help rule in the abdominal wall as a source of the patient’s pain as well as aid in localizing the nidus of the pain. This increase in pain is thought to be caused by the herniation of small amounts of fat into the fascial ring which contains the anterior cutaneous nerve as it turns anteriorly along with the epigastric artery and vein to provide sensory innervation to the anterior abdominal wall (Fig. Patients suffering from anterior cutaneous nerve entrapment will often attempt to avoid eliciting anterior abdominal wall pain by splinting the affected nerve by keeping the thoracolumbar spine slightly flexed to avoid increasing tension on the abdominal musculature. Carnett test is performed by having the patient do a partial sit up with their head lifted completely off the table. Radiographic evaluation of the gallbladder is indicated if cholelithiasis is suspected (Fig. Based on the patient’s clinical presentation, additional testing may be indicated, including complete blood cell count, rectal examination with stool guaiac, sedimentation rate, and antinuclear antibody testing. Computed tomography and ultrasound imaging of the abdomen is indicated if intra- abdominal pathology or an occult mass is suspected (Fig. Computed tomographic and ultrasound images of acute cholecystitis in a patient who presented with anterior abdominal pain. A: Enhanced image through the gallbladder neck shows a mildly distended gallbladder with a mildly thickened wall and some pericholecystic fluid between the gallbladder and the liver and external to the gallbladder. B: Image through the gallbladder fundus shows edema surrounding the mildly distended fundus of the gallbladder. Transverse ultrasound image at the level of the splenic vein shows a heterogeneous hypoechoic texture of the distal pancreas (arrows) relative to the body of the pancreas (P). The patient is asked to identify the painful point that is thought to be the source of the pain. After the clinician confirms by palpation that in fact this is the site of the patient’s abdominal wall pain, the skin overlying the point is prepped with antiseptic solution. A curvilinear low-frequency ultrasound transducer is then placed in the transverse plane just above the previously identified point of nerve entrapment and an ultrasound survey scan is taken (Fig. The skin, subcutaneous tissue, and rectus abdominis muscles as well as the anterior cutaneous nerve are identified (Figs. Color Doppler can be used to help identify the epigastric artery and vein as they turns upward accompanying the anterior cutaneous nerve as it passes anteriorly (Fig. Transverse placement of the ultrasound transducer at the site at which the anterior cutaneous nerve pierces the abdominal wall. Transverse ultrasound image demonstrating external rectus muscle, peritoneal cavity, skin, subcutaneous tissue, and anterior cutaneous nerve. The use of color Doppler can aid in identification of the epigastric artery which accompianies the anterior cutaneous nerve as it passes anteriorly to provide sensory innervation to the anterior abdominal wall. The injection of local anesthetic at the site of anterior cutaneous nerve entrapment can serve as a diagnostic and therapeutic maneuver (Fig. Any significant pain or sudden increase in resistance during injection when performing ultrasound guided suggests incorrect needle placement and one should stop injecting immediately and reassess the position of the needle. Anterior abdominal wall nerve and vessel anatomy: 677 clinical implications for gynecologic surgery. The nerve exits the lateral border of the psoas muscle to follow a curvilinear course that takes it from its origin of the L1 and occasionally T12 somatic nerves to inside the concavity of the ilium (Fig. The ilioinguinal nerve continues in an anterior trajectory as it runs between the layers of the internal oblique and transverse abdominis muscles (Fig. It is at this point that it is the nerve can consistently be identified with ultrasound scanning and is amenable to ultrasound-guided nerve block. The ilioinguinal nerve then perforates the transverse abdominis muscle at the level of the anterior superior iliac spine and its terminal branches provide sensory innervation to the skin over the inferior portion of the rectus abdominis muscle. The ilioinguinal nerve may interconnect with the iliohypogastric nerve as it continues to pass along its course medially and inferiorly, where it accompanies the genital branch of the genitofemoral nerve as well as the spermatic cord in men and the round ligament in women through the inguinal ring and into the inguinal canal (Figs. The distribution of the sensory innervation of the ilioinguinal nerves varies from patient to patient due to considerable overlap with the iliohypogastric nerve. In most patients, the ilioinguinal nerve provides sensory innervation to the upper portion of the skin of the inner thigh and the root of the penis and upper scrotum in men or the mons pubis and lateral labia in women (Fig. The ilioinguinal nerve exits the lateral border of the psoas muscle to follow a curvilinear course that takes it from its origin of the L1 and occasionally T12 somatic nerves to inside the concavity of the ilium. The ilioinguinal nerve continues in an anterior trajectory as it runs between the layers of the internal oblique and transverse abdominius muscles. A–C: In men, the ilioinguinal nerve may interconnect with the iliohypogastric nerve as it continues to pass along its course medially and inferiorly, where it accompanies the genital branch of the genitofemoral nerve as well as the spermatic cord through the inguinal ring and into the inguinal canal. A–D: In women, the ilioinguinal nerve may interconnect with the iliohypogastric nerve as it continues to pass along its course medially and inferiorly, where it accompanies the genital branch of the genitofemoral nerve as well as the round ligament through the inguinal ring and into the inguinal canal.
