Homologous Consists of two morphologically identical chromosomes that have identical gene loci buy cheap colchicine 0.5mg on line different antibiotics for sinus infection, but may have different gene alleles as one member of a homologous pair is of maternal origin and the other is of paternal origin cheap colchicine 0.5 mg antibiotics for sinus infection not helping. On Romanowsky stained blood smears, it appears as a dark purple spherical granule usually near the periphery of the cell. Hydrops fetalis A genetically determined hemolytic disease (thalassemia) resulting in production of an abnormal hemoglobin (hemoglobin Bart’s, γ4) that is unable to carry oxygen. Hypercoagulable state A condition associated with an imbalance between clot promoting and clot inhibiting factors. This can be brought about by an increase in the number of cells replicating, by an increase in the rate of replication, or by prolonged survival of cells. The stimulus for the proliferation may be acute injury, chronic irritation, or prolonged, increased hormonal stimulation; in hematology, a hyperplastic bone marrow is one in which the proportion of hematopoietic cells to fat cells is increased. Hypochromic A lack of color; used to describe erythrocytes with an enlarged area of pallor due to a decrease in the cell’s hemoglobin content. Hypofibrinogenemia A condition in which there is an abnormally low fibrinogen level in the peripheral blood. It may be caused by a mutation in the gene controlling the production of fibrinogen or by an acquired condition in which fibrinogen is pathologically converted to fibrin. Hypogammaglobulinemi A condition associated with a decrease in a resistance to infection as a result of decreased γ-globulins (immunoglobulins) in the blood. Hypoplasia A condition of underdeveloped tissue or organ usually caused by a decrease in the number of cells. A hypoplastic bone marrow is one in which the proportion of hematopoietic cells to fat cells is decreased. The irf may be helpful in evaluating bone marrow erythropoietic response to anemia, monitoring anemia, and evaluating response to therapy. Immune hemolytic An anemia that is caused by premature, immune anemia mediated, destruction of erythrocytes. Diagnosis is confirmed by the demonstration of immunoglobulin (antibodies) and/or complement on the erythrocytes. The cell is morphologically characterized by a large nucleus with prominent nucleoli, a fine chromatin pattern, and abundant, deeply basophilic cytoplasm. Consists of two pairs of polypeptide chains: two heavy and two light chains linked together by disulfide bonds. Immunohistochemical Application of stains using immunologic stains principles and techniques to study cells and tissues; usually a labeled antibody is used to detect antigens (markers) on a cell. Ineffective erythropoiesisPremature death of erythrocytes in the bone marrow preventing release into circulation. Infectious lymphocytosisAn infectious, contagious disease of young children that may occur in epidemic form. The most striking hematologic finding is a leukocytosis of 40—50 X 109/L with 60—97% small, normal-appearing lymphocytes. Serologic tests to detect the presence of heterophil antibodies are helpful in differentiating this disease from more serious diseases. Internal quality control Program designed to verify the validity of program laboratory test results that is followed as part of the daily laboratory operations. Intrinsic factor A glycoprotein secreted by the parietal cells of the stomach that is necessary for binding and absorption of dietary vitamin B12. Ischemia Deficiency of blood supply to a tissue, caused by constriction of the vessel or blockage of the blood flow through the vessel. Jaundice Yellowing of the skin, mucous membranes, and the whites of the eye caused by accumulation of bilirubin. Karyorrhexis Disintegration of the nucleus resulting in the irregular distribution of chromatin fragments within the cytoplasm. Involved in several activities such as resistance to viral infections, regulation of hematopoiesis, and activities against tumor cells.

This handbook was designed for the large number of residents from a variety of disciplines that rotate through pediatrics during their first year of training. It may also be helpful for clinical clerks during their time on the pediatric wards, as well as for pediatric residents and elective students. Hopefully this demystifies some of the ‘pediatric specific’ logistics, and gives a few practical suggestions for drug dosages and fluid requirements. This is intended only to act as a guideline for general pediatrics use, and some drugs, doses, indications and monitoring requirements may differ in individual situations. We would very much appreciate any feedback, suggestions or contributions emailed to ladhanim@mcmaster. It is therefore important to complete a succinct handover within the allotted 30 minutes. The senior residents should touch base with the charge nurses from 3B/3C/L2N to review potential discharges. The two ward Attendings, the Senior Residents and Nurse Managers will attend and discuss potential discharges and bed management. Patients that can go home will be identified at this time and discharges for these patients should occur promptly. Discharge planning should always be occurring and patients that could potentially go home should be discussed by the team the night before. This would then be the time to ensure that if those patients are ready that the patients are discharged. The chart and nursing notes should be reviewed to identify any issues that have arisen over night. The house staff should then come up with a plan for the day and be ready to present that patient during ward rounds. It is not necessary that full notes be written at this time, as there will be time allotted for that later in the day. Ward Rounds: During ward rounds the attending paediatrician, with/without Senior Resident, and house staff will round on patients for their team. All efforts should be made to go bedside to bedside to ensure that all patients are rounded on. Team 1 will start on 3B then proceed to 3C Team 2 will start on 3C then proceed to 3B Team 3 will start on L2N then 4C Case Based Teaching Team 1 and Team 2: There is allotted time for case based teaching. A Junior Resident should be assigned by the Senior Pediatric Resident in advance to present at the case based teaching. The Junior Resident should present the case in an interactive manner to the rest of the teams. After which the Senior Resident should lead a discussion on that topic and the staff Pediatrician will play a supervisory role. Please note that the case based teaching times from 8:00‐9:00 hrs are protected times for learners on the teams. Resident Run Teaching: Time has been allotted for resident run teaching on Tuesday mornings 0800‐ 0900 hrs. The rest of the team, at this time, will continue with discharge rounds and seeing patients. The second Thursday of each month will be morbidity and mortality rounds and all learners should attend these. This is also the time for them to get dictations done and to complete face sheets. It is the goal during this time to get various specialties to come in and teach around patients that are on the ward. The attendings will decide how to split the group up to get the maximum out of these sessions. Although the Senior Pediatric Resident is expected to lead these sessions, the Team 1 and 2 attendings are expected to be there and provide input. Case‐based teaching run by Team 1 and 2 on the 2nd and 3rd Wednesdays and the 4th Wednesday of the month will be Peds.

It is therefore important that those who are susceptible to muscle atrophy exercise to maintain muscle function and prevent the complete loss of muscle tissue purchase colchicine 0.5mg amex virus 101. In extreme cases colchicine 0.5mg on-line human eye antibiotics for dogs, when movement is not possible, electrical stimulation can be introduced to a muscle from an external source. This acts as a substitute for endogenous neural stimulation, stimulating the muscle to contract and preventing the loss of proteins that occurs with a lack of use. They are trained to target muscles susceptible to atrophy, and to prescribe and monitor exercises designed to stimulate those muscles. Age-related muscle loss is also a target of physical therapy, as exercise can reduce the effects of age-related atrophy and improve muscle function. The goal of a physiotherapist is to improve physical functioning and reduce functional impairments; this is achieved by understanding the cause of muscle impairment and assessing the capabilities of a patient, after which a program to enhance these capabilities is designed. Some factors that are assessed include strength, balance, and endurance, which are continually monitored as exercises are introduced to track improvements in muscle function. Physiotherapists can also instruct patients on the proper use of equipment, such as crutches, and assess whether someone has sufficient strength to use the equipment and when they can function without it. Smooth muscle is found in the skin, where it is associated with hair follicles; it also is found in the walls of internal organs, blood vessels, and internal passageways, where it assists in moving materials. Skeletal muscles maintain posture, stabilize bones and joints, control internal movement, and generate heat. The striations are created by the organization of actin and myosin resulting in the banding pattern of myofibrils. The cross-bridging of myposin heads docking into actin-binding sites is followed by the “power stroke”—the sliding of the thin filaments by thick filaments. The length of a sarcomere is optimal when the zone of overlap between thin and thick filaments is greatest. A motor unit is formed by a motor neuron and all of the muscle fibers that are innervated by that same motor neuron. Increasing the number of motor neurons involved increases the amount of motor units activated in a muscle, which is called recruitment. The opposite of hypertrophy is atrophy, the loss of muscle mass due to the breakdown of structural proteins. Muscle atrophy due to age is called sarcopenia and occurs as muscle fibers die and are replaced by connective and adipose tissue. Cardiac muscle fibers have a single nucleus, are branched, and joined to one another by intercalated discs that contain gap junctions for depolarization between cells and desmosomes ++ to hold the fibers together when the heart contracts. Pacemaker cells stimulate the spontaneous contraction of cardiac muscle as a functional unit, called a syncytium. The smooth cells are nonstriated, but their sarcoplasm is filled with actin and myosin, along with dense bodies in the sarcolemma to anchor the thin filaments and a network of intermediate filaments involved in pulling the sarcolemma toward the fiber’s ++ middle, shortening it in the process. Smooth muscle contraction is initiated when the Ca binds to intracellular calmodulin, which then activates an enzyme called myosin kinase that phosphorylates myosin heads so they can form the cross-bridges with actin and then pull on the thin filaments. Smooth muscle can be stimulated by pacesetter cells, by the autonomic nervous system, by hormones, spontaneously, or by stretching. Single-unit smooth muscle tissue contains gap junctions to synchronize membrane depolarization and contractions so that the muscle contracts as a single unit. Single-unit smooth muscle in the walls of the viscera, called visceral muscle, has a stress-relaxation response that permits muscle to stretch, contract, and relax as the organ expands. Multiunit smooth muscle cells do not possess gap junctions, and contraction does not spread from one cell to the next. The nucleus of each contributing myoblast remains intact in the mature skeletal muscle cell, resulting in a mature, multinucleate cell. Smooth muscle tissue can regenerate from stem cells called pericytes, whereas dead cardiac muscle tissue is replaced by scar tissue. Aging causes muscle mass to decrease and be replaced by noncontractile connective tissue and adipose tissue. The correct order for the smallest to the largest unit of reticulum organization in muscle tissue is ________. The diaphragm is a sheet of skeletal muscle that has to contract and relax for you to breathe day and night. If you recall from your study of the skeletal system and joints, body movement occurs around the joints in the body. The system to name skeletal muscles will be explained; in some cases, the muscle is named by its shape, and in other cases it is named by its location or attachments to the skeleton.

Gasometría Evolución Cuando se realiza el diagnóstico tempranamente y se impone el tratamiento sin demoras purchase 0.5mg colchicine visa antibiotic resistance microbiology, antes de las 6 horas de haberse iniciado el cuadro clínico order colchicine 0.5mg with mastercard antibiotics for treatment of uti in pregnancy, la evolución es favorable. Cuando no es así, quedan lesiones irreversibles o que necesitan de otras medidas para mantener la anatomía y función de la extremidad. El enfermo con una desobstrucción arterial demorada, incompleta o insuficiente, puede quedar con claudicación intermitente y el cuadro que la acompaña. La isquemia sostenida del nervio ciático demorada en resolverse, deja el pie “colgando”. El cuadro clínico se resolvió en el tiempo límite de la isquemia muscular, unas 6-8 horas. Quedó la anatomía de la extremidad, pero se perdió su función por músculos pétreos, contraídos definitivamente, no funcionales. Es fácil comprender que la extracción demorada de un émbolo del interior de una gruesa arteria, hará que al restituirse la circulación de los músculos isquémicos durante horas, entren en circulación numerosas sustancias producto del metabolismo anaeróbico, que son vasoactivas y pueden ocasionar si no se tienen en cuenta las medidas necesarias, un estado de choque que puede ser irreversible. No existe una relación exacta entre la masa muscular isquémica y la intensidad del choque o la insuficiencia renal. Existe la tendencia generalizada de que en los “problemas circulatorios” debe elevarse la extremidad. Aplicar calor aumenta el metabolismo que no puede ser compensado por el oxígeno que no llega y se produce fácilmente una quemadura que hace perder la extremidad. Mejor es abrigar la extremidad para que no pierda más calor y sobre todo para que no se golpee con los movimientos del traslado. Sólo existen unas escasas 6 a 8 horas desde el inicio del cuadro, para resolverlo. Las siguientes medidas no son posibles en todos los consultorios, dispensarios o policlínicos, pero las que se puedan, deben iniciarse cuanto antes por parte del médico que hace el diagnóstico para reducir secuelas, amputaciones y muertes y por supuesto están orientadas a los cuadros de insuficiencia arterial aguda por embolia o trombosis. Es lógico que los traumatismos arteriales y el hematoma disecante se traten de acuerdo con esas circunstancias particulares: - Suero “vasoactivo”: Solución salina fisiológica 500 ml Papaverina (500 mg) Procaína 2% (200 mg) A goteo muy lento, de 6-8 gotas por minuto. La arteria que ha aprisionado el émbolo, puede liberarlo y dejarlo pasar a un lugar donde ya la incompatibilidad de tamaños hace imposible que continúe su migración distal. Realizar al menos la primera inyección mientras se logra trasladar al enfermo a un lugar especializado. Los hematomas disecantes de la aorta son muy graves y las indicaciones de las diferentes posibilidades tienen esquemas complejos y difíciles, al tiempo que se necesita cirugía con circulación extracorpórea. Cada vez se utilizan con mejores resultados, los caros y aún lejanos stents de implantación endovascular para los hematomas disecantes. Rehabilitación Se encamina a devolver al paciente a la comunidad y que realice sus labores habituales, con énfasis en el tratamiento de las secuelas, principalmente las neurológicas. Mencione algunas posibilidades de tratamiento médico en diferentes lugares de asistencia médica. Conocer los dos elementos necesarios para el desarrollo de estas graves infecciones. Enfatizar en las cuatro formas clínicas clásicas, con interés en la contaminación simple. Otorgar la mayor importancia a los elementos de prevención de estas sepsis como la mejor forma de tratamiento. Enfatizar que en el período de estado el único tratamiento salvador es el quirúrgico. Su evolución ha ido cambiando en cuanto a número de casos, ya que mantiene una tendencia al descenso. Sin embargo, los pacientes que las presentan, si bien han tenido nuevas posibilidades dados los conceptos mejorados, los modernos antibióticos y quimioterápicos, la introducción de la oxigenación hiperbárica y otros adelantos, sufren aún de elevados índices de mutilaciones de sus extremidades o vísceras, y lo que es peor, de mortalidad. Resulta entonces oportuno, recopilar lo que de ellas se conocen para lograr una actualización del tema y una remodelación de conceptos que nos permitan una real comprensión, así como mejores resultados en la atención de estos infelices enfermos que aunque contados, presentan una elevada mortalidad. Ellos afectan el tejido celular subcutáneo, pero principalmente a los músculos (mionecrosis clostridiana, miositis clostridiana o gangrena gaseosa propiamente dicha), aunque también algunos órganos internos. En general antecede un traumatismo o cirugía, aunque también puede presentarse de forma aparentemente espontánea, sin trauma previo, pero con enfermedades y factores generales condicionantes bien establecidos. Las zonas más frecuentemente involucradas son las extremidades afectadas por traumas u operaciones, las heridas abdominales y el útero. De igual manera existen formas viscerales, a las que se les ha dado preferentemente el apellido de enfisematosas, como colecistitis enfisematosa, pielonefritis enfisematosa y otras.
