Fortunately we can prevent the emergence of drug resistance in virtually all cases if we take enough trouble to ensure that the best drug combinations are prescribed and that the patient takes them as directed. It might be suggested that giving a risky combination of drugs, or even giving a drug alone, will not matter if it is only for a short time. It is true that it may not matter in a number of patients, but in some it can matter very much and may make all the difference between survival and death. Te development of drug resistance may be a tragedy not only for the patient himself but for others. If physicians come to apply thoroughly the present knowledge about preventing drug resistance, this percentage should steadily diminish”.

The sacrospinous ligament runs from the sacrum to the ischial spine purchase levitra plus 400mg with visa, and the sacrotuberous ligament runs from the sacrum to the ischial tuberosity discount 400 mg levitra plus free shipping. The sacrospinous ligament spans the sacrum to the ischial spine, and the sacrotuberous ligament spans the sacrum to the ischial tuberosity. The sacrospinous and sacrotuberous ligaments contribute to the formation of the greater and lesser sciatic foramens. What is the large opening in the bony pelvis, located between the ischium and pubic regions, and what two parts of the pubis contribute to the formation of this opening? The sacrospinous and sacrotuberous ligaments also help to define two openings on the posterolateral sides of the pelvis through which muscles, nerves, and blood vessels for the lower limb exit. This large opening is formed by the greater sciatic notch of the hip bone, the sacrum, and the sacrospinous ligament. The smaller, more inferior lesser sciatic foramen is formed by the lesser sciatic notch of the hip bone, together with the sacrospinous and sacrotuberous ligaments. The broad, superior region, defined laterally by the large, fan-like portion of the upper hip bone, is called the greater pelvis (greater pelvic cavity; false pelvis). This broad area is occupied by portions of the small and large intestines, and because it is more closely associated with the abdominal cavity, it is sometimes referred to as the false pelvis. More inferiorly, the narrow, rounded space of the lesser pelvis (lesser pelvic cavity; true pelvis) contains the bladder and other pelvic organs, and thus is also known as the true pelvis. The pelvic brim (also known as the pelvic inlet) forms the superior margin of the lesser pelvis, separating it from the greater pelvis. The pelvic brim is defined by a line formed by the upper margin of the pubic symphysis anteriorly, and the pectineal line of the pubis, the arcuate line of the ilium, and the sacral promontory (the anterior margin of the superior sacrum) posteriorly. This large opening is defined by the inferior margin of the pubic symphysis anteriorly, and the ischiopubic ramus, the ischial tuberosity, the sacrotuberous ligament, and the inferior tip of the coccyx posteriorly. Because of the anterior tilt of the pelvis, the lesser pelvis is also angled, giving it an anterosuperior (pelvic inlet) to posteroinferior (pelvic outlet) orientation. Comparison of the Female and Male Pelvis The differences between the adult female and male pelvis relate to function and body size. In general, the bones of the male pelvis are thicker and heavier, adapted for support of the male’s heavier physical build and stronger muscles. Because the female pelvis is adapted for childbirth, it is wider than the male pelvis, as evidenced by the distance between the anterior superior iliac spines (see Figure 8. The ischial tuberosities of females are also farther apart, which increases the size of the pelvic outlet. Because of this increased pelvic width, the subpubic angle is larger in females (greater than 80 degrees) than it is in males (less than 70 degrees). The female sacrum is wider, shorter, and less curved, and the sacral promontory projects less into the pelvic cavity, thus giving the female pelvic inlet (pelvic brim) a more rounded or oval shape compared to males. The lesser pelvic cavity of females is also wider and more shallow than the narrower, deeper, and tapering lesser pelvis of males. Because of the obvious differences between female and male hip bones, this is the one bone of the body that allows for the most accurate sex determination. Overview of Differences between the Female and Male Pelvis Female pelvis Male pelvis Bones of the pelvis are lighter and Bones of the pelvis are thicker and Pelvic weight thinner heavier Pelvic inlet shape Pelvic inlet has a round or oval shape Pelvic inlet is heart-shaped Lesser pelvic cavity Lesser pelvic cavity is longer and Lesser pelvic cavity is shorter and wider shape narrower Subpubic angle is greater than 80 Subpubic angle Subpubic angle is less than 70 degrees degrees Pelvic outlet shape Pelvic outlet is rounded and larger Pelvic outlet is smaller Table 8. At times, a forensic pathologist will be called to testify under oath in situations that involve a possible crime. Forensic pathology is a field that has received much media attention on television shows or following a high-profile death. While forensic pathologists are responsible for determining whether the cause of someone’s death was natural, a suicide, accidental, or a homicide, there are times when uncovering the cause of death is more complex, and other skills are needed. Forensic anthropology brings the tools and knowledge of physical anthropology and human osteology (the study of the skeleton) to the task of investigating a death. The science behind forensic anthropology involves the study of archaeological excavation; the examination of hair; an understanding of plants, insects, and footprints; the ability to determine how much time has elapsed since the person died; the analysis of past medical history and toxicology; the ability to determine whether there are any postmortem injuries or alterations of the skeleton; and the identification of the decedent (deceased person) using skeletal and dental evidence. Due to the extensive knowledge and understanding of excavation techniques, a forensic anthropologist is an integral and invaluable team member to have on-site when investigating a crime scene, especially when the recovery of human skeletal remains is involved. When remains are bought to a forensic anthropologist for examination, he or she must first determine whether the remains are in fact human. Once the remains have been identified as belonging to a person and not to an animal, the next step is to approximate the individual’s age, sex, race, and height. The forensic anthropologist does not determine the cause of death, but rather provides information to the forensic pathologist, who will use all of the data collected to make a final determination regarding the cause of death. These are the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges (see Figure 8. The tibia is the larger, weight-bearing bone located on the medial side of the leg, and the fibula is the thin bone of the lateral leg. The posterior portion of the foot is formed by a group of seven bones, each of which is known as a tarsal bone, whereas the mid-foot contains five elongated bones, each of which is a metatarsal bone. It is the longest and strongest bone of the body, and accounts for approximately one-quarter of a person’s total height. The rounded, proximal end is the head of the femur, which articulates with the acetabulum of the hip bone to form the hip joint. The fovea capitis is a minor indentation on the medial side of the femoral head that serves as the site of attachment for the ligament of the head of the femur. This ligament spans the femur and acetabulum, but is weak and provides little support for the hip joint. It articulates superiorly with the hip bone at the hip joint, and inferiorly with the tibia at the knee joint. Multiple muscles that act across the hip joint attach to the greater trochanter, which, because of its projection from the femur, gives additional leverage to these muscles. The lesser trochanter is a small, bony prominence that lies on the medial aspect of the femur, just below the neck.

Risk factors • Geographical - it occurs commonly in the western world accounting for 3-5 percent of deaths but is rare tumor in Far East like Japan generic 400mg levitra plus with mastercard. Pathology: Breast cancer may arise from the epithelium of the duct system starting from the nipple to the end of lactiferous ducts which is in the lobule 400mg levitra plus visa. It may be entirely in situ (with out breaching basement membrane) or may be invasive. The degree of differentiation of a tumor is usually described by three grades well differentiated, moderately or poorly differentiated. It tends to involve the skin and to penetrate the pectoral muscles, and even the chest wall. Involvement of lymph nodes is not necessarily a chronological event in the evolution of the carcinoma, but rather a marker of the metastatic potential of that tumor. In advanced diseases there may be involvement of supraclavicular nodes and of any contra lateral lymph nodes. It is by this route that skeletal metastasis occurs in decreasing frequency to the lumbar vertebra, femur, thoracic vertebra, rib and skull. Metastasis can also occur to the liver, lungs and brain and occasionally to the adrenal glands and ovaries. Clinical presentation While any portion of the breast may be involved, breast cancer commences most frequently in the upper outer quadrant. Prognosis of breast cancer: The best indicators of likely prognosis in breast cancer are tumor size and lymph node status. Other prognostic factors include: - Invasive and metastatic potential - Histological grade of tumor - Estrogen receptor status - Patient age and menopausal status are some of the factors Treatment of Breast Cancer: Treatment of breast cancer is a multi disciplinary approach. It largely depends on clinical stage and other tumor characteristics described previously. Modes of treatment include: • surgery • radiotherapy and • Medical therapy (including chemotherapy and hormonal therapy. A-20 year old female patient presents with a solitary painless lump in the breast. A thirty-five year-old nulliparous woman comes with history of swelling in the breast of 2-months duration. In association with this, the patient has moderate fever, decreased appetite and weight loss. List the most important laboratory investigations which help you confirm the diagnosis. On Physical examination, the tumor measured 4cm, its non-mobile and rough surfaced. Introduction Acute upper airway obstruction is a surgical emergency with no time to lose. Infants are vulnerable more than adults due to small diameter of the airway, longer soft palate, more posterior pharyngeal soft tissues, compliant epiglottis, etc. Generally, in any patient with thoracic problem, chest physiotherapy, that is incentive spirometry if available or inflating a glove or intravenous fluid bag with deep inspiration and expiration and early movement is of paramount importance for smooth recovery of the patient. It is usually characterized by stridor (noisy breathing); suprasternal retraction; tachycardia and cyanosis develop as obstruction becomes complete. If a foreign body aspiration is suspected, tilt the patient’s head down and slap the patient sharply across the back. Then, explore the pharynx and mouth by finger and if possible, urgent laryngoscopy should be done. If indicated, intubate the airway immediately, otherwise do emergency cricothyroidotomy (insert wide bore needle to the cricothyroid membrane) and give 100% oxygen until intubation or proper tracheostomy is done. It is indicated to by- pass upper airway obstruction, for drainage of the respiratory tract and to provide assisted ventilatory support. Tracheostomy should be performed in operating room under general anaesthesia with intubation, if possible, especially in case of children. But if very urgent situation is encountered, do cricothyroidotomy while preparing for tracheostomy. Make incision over fourth tracheal ring transversely or vertically in case of emergency. Dissect strictly in midline to separate the strap muscles and pre tracheal fascia to expose the trachea. Open the trachea by midline incision through three adjacent tracheal rings, usually rd th th 3 , 4 and 5 , after holding upper end of cricoid cartilage using fine cricoid hook. Hold open cut edge by tracheal dilator and insert a tube which comfortably fits the trachea while the anaesthesiologist withdraws the endotracheal tube. Aspirate tracheal secretion soon after initial incision on the trachea and repeat after the tube in place. Humidify inhaled gas as near to body temperature as can be achieved by frequent application of saline soaked gauze over the tube. Tracheostomy toilet from 10 minutes to as long as two hours as needed and if there is inner tube take it out every four hours and wash it. The terrible death toll related to chest injuries is avoidable by simple measures. It results in hemothorax in more than 80% and pneumothorax 146 in nearly all cases. It should be considered as thoracoabdominal if penetration is below fourth intercostal space. Tightly dress any sucking wound and look for signs of tension pneumothorax (distended neck veins, shift of the trachea, hyper resonance with decreased air entry), cardiac tamponade (hypotension, distended neck vein and distant heart sounds), massive hemothorax and flail chest all of which can compromise ventilation despite patent airway and adequate oxygenation. Control extreme hemorrhage and restore circulation: Insert wide bore cannula for fluid and blood transfusion.
