The best treatment begins as close to gastritis uti discount 400 mg sevelamer with visa birth as possible and consists of repositioning of the foot gastritis high fiber diet buy 400 mg sevelamer free shipping, either manually or surgically gastritis and exercise buy discount sevelamer 400mg on-line, followed by casting gastritis diet of hope sevelamer 400 mg sale. Forced dorsiflexion by serial casting must be avoided as a rocker-bottom foot may develop gastritis video discount sevelamer 400 mg fast delivery. Ponsetiās technique of manipulation and casting, followed by Achilles tenotomy if needed, has shown up to 90% success, reducing the need for surgical correction. Larger infants (such as those born to mothers with gestational diabetes) are at greater risk, as are breech and assisted (forceps or vacuum) deliveries. Erb-Duchenne palsy (C5, C6) or waiterās tip deformity has the best prognosis, followed by Klumpkeās palsy (C8-T1); complete plexus palsy has the worst prognosis. Occasionally, a clavicle fracture accompanies the injury, and should be ruled out. Approximately 80% to 90% of children recover spontaneously, but there are indicators for a better prognosis. Traction injuries tend to recover over time, whereas avulsion injuries are less responsive. If movement is not regained in the ļ¬rst 4 months, the child should be referred for further evaluation and possible surgical intervention. Initial therapy involvement includes positioning to decrease further stretch on the shoulder, and prone-supported weight-bearing activities to stimulate muscle activity. Therapy can also minimize the likelihood of a contracture when the muscles recover to whatever level they can reach. Tactile stimulation along the muscles, stimulation of the grasp reflex, and sharp/dull testing should produce active movement in innervated muscles. The Moro test (dropping the child backward suddenly in a controlled fashion) is often used, but can cause additional tension on the shoulder. Can physical therapy to reduce spasticity improve function in children with cerebral palsy? No scientiļ¬c evidence indicates that physical therapy can reduce spasticity over the long term. Therapy techniques have been shown to be effective in the short term; however, signiļ¬cant spasticity often needs to be addressed to improve functional independence. However, evidence has shown that therapy to strengthen spastic muscles has a positive effect, and does not negatively influence spasticity. Typical growth and development can also cause changes that shorten spastic muscles and can cause loss of function. Of the various medical treatments for spasticity reduction, the easiest to use is an oral agent such as diazepam (Valium) or oral baclofen. The dosage needed to cross the blood-brain barrier for effectiveness, however, may make the child sleepy. Baclofen delivered intrathecally from a battery powered pump has helped some children who are severely limited by spasticity, and tends to affect legs more than arms. For children with more localized issues, intramuscular injection of botulinum toxin type A (Botox) prevents the presynaptic release of acetylcholine at the nerve muscle junction. It is seen most commonly in the knee (in the intercondylar region of the medial femoral condyle). Lesions are staged 1 through 4, with stage 1 being a small area of compression and stage 4 having a displaced loose body. Pain is detected at about 30 degrees of knee flexion and relieved by lateral tibial rotation. Children with open epiphyseal plates tend to respond well to 2 to 3 months of casting. If a loose fragment is present or if the subchondral bone is involved, surgery (usually arthroscopic) is indicated. Osgood-Schlatter disease involves enlargement and microfractures in the apophysis of the tibial tubercle (where the quadriceps inserts) and is commonly seen in young, highly active adolescent males who are going through a rapid growth spurt. Males are typically affected from ages 13 to 14 years, whereas girls more often have symptoms from the age of 11 or 12. Treatment is directed at relief of symptoms with heat or ice massage, changes in activity, use of knee pads, and administration of antiinflammatory medication. While the problem is being treated, flexibility and isometric strengthening exercises for the quadriceps and hamstring muscles may help. Sometimes a separate ossicle (small bone) develops under the patellar tendon and may need to be removed surgically. Sinding-LarsenāJohansson syndrome is a traction apophysitis at the distal patella pole. It is seen most often in children aged 4 to 12 years and affects boys more often than girls (4:1). The hip progresses from synovitis to an avascular stage to fragmentation to reossiļ¬cation and ļ¬nally heals within approximately 18 to 24 months following reossiļ¬cation. Sprengelās deformity is a congenital elevation of the scapula, often accompanied by tethering of the scapula to the spinal column by a bony, cartilaginous, or soft tissue band. Because the problem originates in the cervical region, children with Sprengelās deformity may have associated congenital anomalies of the cervical spine (Klippel-Fiel syndrome). What type of individual is most likely to suffer from a slipped capital femoral epiphysis? Obese adolescent males, ages 10 to 16, are most likely to have a āslipāor displacement of the capital. Because of this symptom, the diagnosis is often incorrect as a result of isolated evaluation of the knee. The condition is more common in African Americans and patients with endocrine abnormalities. Treatment usually requires surgical pinning with in-situ screw ļ¬xation to stabilize āthe slipā and to close the physis. Partial weight-bearing is suggested (even if minimal) because nonāweight-bearing requires use of the hip muscles to maintain the leg in the air and puts more stress on the hip than resting the foot on the floor. Repetitive stress may cause epiphysiolysis at the proximal humerus (little league shoulder) or stress the medial epicondyle apophysis (little league elbow). Femoral anteversion decreases from 40 to 15 degrees at maturity, whereas tibial rotation increases from 5 degrees of external rotation to 15 degrees at maturity. This is a depression of the sternum, generally related to poor muscle tone and respiratory insufļ¬ciency. Abdominal support to improve the effectiveness of the diaphragm could help to decrease the pectus. Also referred to as pulled elbow, temper tantrum elbow, or supermarket elbow, nursemaidsā elbow is subluxation of the radial head from the annular ligament. The mechanism of injury is usually a traction force on the arm, often seen when children are swung by the hands or an arm is jerked rapidly. Radiographs showing displacement of 3 mm or more from the capitellum suggest sub luxation. While not well-deļ¬ned, growing pains are nonspeciļ¬c intermittent pains, usually occurring at night, but often coming and going. They can be in the quads, calves, or other muscle groups, and generally occur during growth spurts. It is hypothesized that they are related to rapid bone growth, and muscle fatigue while trying to accommodate to the new length. Salter-Harris classiļ¬cation is the most well-deļ¬ned system for identifying physeal fracture. The breasts and kidneys are also altered as well as the metabolic and dermatologic functions of the body. Most systems of the body undergo change during the 9 months of pregnancy, including the reproductive, cardiovascular, gastrointestinal, respiratory, and endocrine systems. Some of the cardiovascular changes during pregnancy are the following: blood volume increases approximately 50%; dilutional anemia occurs because of an initial early increase in plasma volume and a slower initial increase in red cell mass; pulse rate increases 10 to 15 beats/min; chambers of the heart dilate and the position of the heart changes, rotating outward and to the left; stroke volume and cardiac output increase 30% to 50%; blood pressure decreases slightly; venous return to the heart is affected by the increasing size of the uterus (especially in the supine position). In well-conditioned athletes, blood flow to the uterus and heat dissipation may be improved with exercise because of increased blood volume, as compared to sedentary women. The overall vital capacity is unchanged; the diaphragm elevates and the rib cage expands and flares; the residual volume decreases and the tidal volume/oxygen consumption increases. The respiratory changes that are occurring with the mother are ampliļ¬ed with the fetus. Therefore if the mother is experiencing a persistent state of hypoxia or acidosis while exercising, the fetus will experience these respiratory changes to a greater degree. It is for this reason that prolonged anaerobic exercise is not recommended, or aerobic exercise that causes dyspnea. The center of gravity moves up and forward, causing flexion in the cervical spine and increased lordosis in the lumbar spine. Active women may want to opt for swimming or low-impact aerobics rather than running and physical sports. Maintain the supine position longer than 3 minutes after the fourth month of pregnancy. Radiographic evidence has shown changes beginning during the ļ¬rst trimester with maximum relaxation at term. Rupture of the pubic symphysis associated with pregnancy is rare but can occur in late pregnancy or with delivery. The hormone relaxin is released by the third month of pregnancy, and under its influence, increased movement is experienced throughout the vertebral spine and pelvis. Many pregnant women complain of low back pain, which often is caused by the many physical changes of pregnancy: added weight, increased lordosis, changes in the center of gravity, loose pelvic ligaments, and poor muscle tone. Diastasis recti abdominis is the separation of the two recti muscles in the abdomen. It often is undetected in pregnancy and contributes to back pain, which may be the primary problem because the diastasis itself is not painful. During shifts from supine to sitting position, a bulge may be seen along the center of the abdomen. The woman is placed in the supine position with her knees bent and no pillow under her head. The therapist palpates the rectus muscle at the level of the umbilicus while the client is asked to lift her head. The therapistās ļ¬ngers are horizontal to the rectus muscles, and if they sink into a gap of two or more ļ¬ngersā width, the test is considered positive for diastasis recti abdominis. Two ļ¬ngers above and two ļ¬ngers below the umbilicus are also tested on subsequent head lifts. Traditional curl-ups and sit-ups should be avoided if the diastasis is larger than two ļ¬ngers in width. Leg slides and isometric abdominal control help to maintain strength during the pregnancy. Often a low-slung brace worn as an abdominal lift helps to decrease the load on the muscles and alleviates back pain.

Oral treatment with metronidazole or vancomycin is recommended, but there is a major problem with symptomatic recurrence after treatment. Replacement of normal flora by the administration of donor stool through colonoscopy or nasogastric/duodenal routes is becoming increasingly popular. The most common risk factors were prior exposure to antibiotics or proton-pump inhibitors and underlying inflammatory bowel disease. Three procedures were carried out as inpatients and 24 in the outpatient gastroenterology unit. At 4-week follow-up, all patients reported clinical resolution of their diarrhoea after a single treatment and there were no recurrences. In most cases it can be administered via the nasogastric route in the outpatient department. Meticulous prescription practice by clinicians practising in hospitals and outpatient settings, with particular attention to antimicrobials and chronic medication, is urgently required to prevent this debilitating and potentially life-threatening condition. It is a potentially life-threatening condition acquired infections as part of the infection prevention and control with mortality as high as 33% and a 28% possibility of relapse. A meta-analysis conducted are healthcare associated, occurring in hospitals and long-term in 2010 suggested that there may be a benefit to using probiotics in care facilities, but outpatient acquisition has also been described. We hope to create awareness in the healthcare profession of who may be at risk and the importance of judicious antibiotic been reported to be as high as 50%, and if a patient has experiencedPrior use of antibiotics prescription to prevent this condition. We highlight clinical methods one recurrence, the risk of subsequent recurrence is even higher. Finally, we discuss funding issues in the private health susceptibility to and recurrence of infection.

Overcoming barriers to efective recognition and diagnosis ofClostridium difcileinfection. The timescales restricted the ability to test the study design and have necessitated the use of routinely available data. It has not been possible, and is not within the remit of this investigation, to evaluate the accuracy or comparability of these data between hospitals. There are particular concerns over the use of historic hospital activity data (from 2006 ā 2007) for denominators and the attribution of cause of death from death certificates. Outputs are reported retrospectively in quarterly reports, is quality assured and acts as a back up to local surveillance. This should be undertaken by the clinical team responsible for the patientās care in line with local Clinical Governance procedures to establish possible reasons, and to identify any actions necessary to minimise risk in the future. To date, it has focussed on harmonising data collection across the country, ensuring data quality and providing information to guide the key interventions being taken by hospitals to assist in reducing the number of cases. National surveillance is an important activity allowing monitoring of trends over time and comparisons of boards with the Scottish average; however, it does not replace the need for supplementary local surveillance. Aims the aim of this review was to assess whether the reported rate of infection. If there were clusters of cases in any of the acute hospitals during the defined period. It was beyond the remit of this review to demonstrate why any difference between hospitals exist or if any such differences are real or artefactual. Data were collected by month for the period of the investigation (1 December 2007 ā 31 May 2008). Shortly after the protocol was sent out it became apparent that the requested denominator data would not be available from several hospitals at such short notice. Experience from a recent case note review in Glasgow suggests that the majority of A49. For this exercise it was assumed that the proportion of patients in acute care relative to the total number of patients in healthcare remained reasonably constant for the period of the review.
Free perforation of an ulcer can be diagnosed by the demonstration of free air in the abdomen gastritis keeping me up at night order discount sevelamer on line. Penetration of an ulcer into adjacent organs may cause visible swelling of the structures involved acute gastritis diet plan purchase generic sevelamer online.

Ultrasound is suitable for visualizing ulcers in the distal stomach (water contrast) and the duodenal bulb in many cases but cannot be used to exclude ulcers, especially atypical gastric ulcers situated elsewhere. The wall of the bulb is swollen and more echo rich than the normal wall of the distal stomach Fig. Additionally, a little ļ¬uid is visible, but no free air is seen in the abdomen, indicating that there is no free perforation 232 Fig. The line marks the duodenum; the interrupted line marks the narrowed lumen a b Neoplasms Gastric carcinoma Gastric cancers are echo poor, the echo pattern being similar to that of the normal mucosa. Small carcinomas limited to the mucosal and submucosal layer (early gastric carcinomas, stage 1 tumours) can be visualized only if a high resolution transducer and the water-contrast method are used or by endoscopic ultrasound (see also Fig. In cross-section, a ring-like fgure consisting of the echo-poor thickened wall and the stenotic lumen, marked by strong echoes, is seen and is termed a ācockadeā, āpseudokidney signā or ātarget-like lesionā (Fig. Difuse growing carcinomas cause thickeningof theentire gastric wallby up to 10ā15 mm. Enlarged, round, echo-poor lymph nodes are highly indicative of metastases but can also be caused by an infammatory reaction. Normal cardia, transverse scan distal to the hiatus (arrow) (vc, vena cava; ao, aorta) 233 Fig. Advanced carcinoma of the antrum (19 mm) causing distal stenosis of the stomach Fig. Cross-section (a) and longitudinal scan (b) show that the entire stomach wall is homogeneously thickened (12 mm). Advanced lymphomas destroy the layers and cause echo-poor thickening of the whole gastric wall. The success of treatment is demonstrated as soon as thethickness decreases and thediferentlayers become visible again (Fig. Transverse and longitudinal scans show thickened dorsal wall (10 mm) with an irregular pattern a b Fig. From thelumen,such tumoursarecovered withtwoor three layers (interface plus mucosal and, mostly, submucosal layer), the so-called ābridging signā (Fig. Usually, they are found accidentally but sometimes as a source of bleeding if ulceration of the mucosa has developed. The origin of a submucosal tumour found during ultrasonic examination of the abdomen may frst remain unclear but can be revealed by useof thewater-contrasttechnique. To diferentiate between a submucosal tumour and an impression by a process outside the stomach, ultrasound is the best method. Three layers (arrow) are seen between the water-ļ¬lled lumen and the tumour (T), which clearly indicates its origin in the fourth layer (ābridging signā) 237 Differential diagnosis A thickened gastric wall without discernible layers is strongly indicative of malignancy, advanced cancer or malignant lymphoma. A thickened wall with the typical layers still visible is a more ambiguous fnding. Malignancy cannot be excluded, as the layers are ofen discernible in carcinomas of the difuse type (linitis plastica); however, all difuse infammatory and other disorders are possible, as listed with some diferential aspects in Table 11. A normal (not thickened) muscle layer is considered to be a sign of a benign disorder, but a low-grade malignant lymphoma may involve the mucosa exclusively in the earlier stages. An ulcer might also be diagnosed diferentially, especially if the lesion is small and located in the distal part of the stomach. The transition of a tumour to the normal wall is abrupt, whereas the reactive thickened wall in benign ulcers shows a graduated transition to the normal wall. Although ultrasound can be used for some diferential diagnoses, mentioned above, it is not usually suitable for distinguishing between benign and malignant ulcers. They therefore difer clearly from the āpseudokidney signā of typical gastric carcinomas. The ultrasonic fnding of bright echoes in the centre of gastric carcinomas (marking the narrowed lumen) also distinguishgastrictumoursfromsolidtumoursoftheneighbouringorgans. Diferentiation of larger submucosal tumours from solid tumours of the surrounding structures is, however, ofen possible only with the water-contrast method. Other epithelial tumours of the stomach, such as carcinoid tumours, are seen as smallpolypsbygastroscopy. Distension of the stomach without signs of a distal tumour may be due to an ulcer in the pylorus channel but may also be seen in an advanced stage of vegetative (diabetic) neuropathy. Small and large bowel Indications The indications for ultrasonography of the small and large bowel are: bowel obstruction abdominal pain suspected appendicitis diarrhoea lasting longer than a few days (complications? Generally, ultrasound is not suitable for diagnosing carcinomasof thelargebowel, as only advanced tumours can be visualized. It may, however, be useful for fnding (advanced) tumours, especially lymphomas, in the small bowel, which is not easily accessible by endoscopy. Imaging modalities such as ultrasound are not needed to diagnose or manage acute infective enterocolitis but are useful in looking for complications or other 238 disorders in cases with an uncommon (long) course. As discussed for examination of thestomach, thewater-contrast technique gives a good contrast between the lumen and the wall. Hydrocolonosonography is, therefore, recommended by some authors for delineation of the inner surface of the wall and to visualize small lesions. For this technique, the colon must be cleaned by laxative intestinal lavage, as for colonoscopy. Intravenous application of 20 mg scopolamine N-butyl bromide (Buscopan) is useful to stop peristalsis and for better distension of the colon. If examination of the small bowel is indicated, it may be useful for the patient to drink up to 500 ml of water or another suitable fuid. When the water-contrast method is used, the patient may also be turned in an oblique position. Scanning technique It is useful to start with a longitudinal scan of the right liver lobe to check that the instrument has the correct setting. Ten, longitudinal scans of the whole abdomen are carried out, with the liver, kidneys and aorta as landmarks. Gas in the bowel can be displaced by applying slight pressure with the transducer. For examination of the appendix, the landmarks are the caecum, the terminal ileum and the iliac vessels. The examination is carried out by application of slight pressure in longitudinal and oblique scans. Examination of a patient with acute appendicitis should always include the neighbouring organs, especially the terminal ileum, the lymph nodes and the organs of the small pelvis. Normal ļ¬ndings The duodenum is relatively fxed and can be visualized around thehead of thepancreas and in its further course to the ligament of Treitz. It is identifable mainly on the basis of its content, disturbing gas or echo-poor fuid. The 14ā16 loops of the bowel are situated in the middle part of the abdomen, surrounded by the colon. The wall is less than 3 mm thick and consists of an outer, echo-poor layer, corresponding to themuscle layer, and aninner, echo-rich layer due to thesubmucosa and theinterface echoes between thefolds of themucosa and thelumen (Fig. When there is water inside the lumen, ultrasound can reveal the complex inner surface of the mucosa, with the longer villi of the jejunum and the shorter villi 239 of the ileum (Fig. The last loop of the ileum is not difcult to identify; it is located in the lef lower quadrant, with a course from caudal, medial and dorsal to the caecum, which is situated more laterally, cranially and ventrally. The complex structure of the ileocaecal valve can be seen with high-quality ultrasound (Fig. The peristaltic movement of the bowel can be visualized, especially if the loops are flled with fuid. Note the ļ¬ne pattern of the Kerckring folds (jejunum) The colon is identifed by its largerdiameter, thehaustra coli and its typical course. The anatomically fxed ascending colon is seen on the right side, with the right fexure close to the gall-bladder. The transverse part has a more variable course, whereas the course of the descending colon is fxed on the lef side in front of the iliopsoas muscle. The sigmoid shows no haustra and turns to the midline and backward to the dorsal wall of the bladder. The distal and upper parts of the sigmoid can be demonstrated by using the full bladder as an acoustic window (Fig. The shadow originating at the front of intestinal gas covers the dorsal wall and the structures behind the colon a b 241 The appendix (Fig. With ultrasound, it is sometimes possible to demonstrate the normal appendix, but this cannot be done routinely, as it is a tubular structure about 8 cm long with a diameter of 3ā6 mm. It difers from the ileum in that it has a blind end and does not show peristaltic movement. Pathological ļ¬ndings Inļ¬ammatory bowel disease Enterocolitis When the bowel is infected with certain microorganisms, the mucosa and submucosa swell and there is augmented secretion of fuid and hyperperistalsis. Ultrasound shows a thickened, echo-poor wall, while the contents of the segments are more or less echo free. Teir pattern is less echo poor, and the echo-rich āhilus signā is still seen (Fig. The echo-poor mucosa of the terminal ileum is thickened, but the deeper layers are not affected. This ultrasonic indication is not specifc but, with clinical background information, is typical enough for diagnosis of this disease (Fig. The wall is thickened (7 mm), mainly due to swelling of the mucosal and submucosal layers. The whole wall of the descending colon is heavily swollen (thickness, 14 mm) and altogether echo poor Whipple disease The ultrasonic features of this rare bacterial disorder are similar to those of other acute infammatory diseases of the small bowel, with fuid-flled intestinal loops and hyperperistalsis. However, a remarkably echo-rich wall and enlarged lymph nodes with an echo-rich pattern are characteristic. Diverticulitis Diverticula, or, more precisely, pseudodiverticula, are common in developed countries. Ultrasound can be used to visualize them as small areas within the wall, marked by a strong air echo (Fig. Diverticulitisdevelopswitherosionoftheinnersurface,followedbymicroperforation of thediverticula and aninfammatoryreaction of thesurroundingtissue. It is visualized by ultrasound as a small, echo-poor lesion on the outside of the thickened wall, covered 243 by an echo-rich cap of fatty tissue (Fig. The condition causes acute abdominal pain and is easy to locate if the transducer follows the pain point.

This is an ovarian teratoma arising from argentaffin cells of intestinal epithelium in the teratoma. Dysgerminoma Dysgerminoma is an ovarian counterpart of seminoma of the testes (page 709). About 10% of are separated by scanty fibrous stroma that is infiltrated by lymphocytes. More often, endodermal sinus tumour is found in combination with other germ cell tumours rather than in pure form. Histologically, like its testicular counterpart, the endo dermal sinus tumour is characterised by the presence of papillary projections having a central blood vessel with perivascular layer of anaplastic embryonal germ cells. Such structures resemble the endodermal sinuses of the rat placenta (Schiller-Duval body) from which the tumour derives its name. Gestational choriocarcinoma of placental origin tumours, pure thecomas, combination of granulosa-theca cell is more common and considered separately later (page 752). Pure granulosa cell origin is rare while its combination with other germ cell tumours may occur at all ages. The patients are usually young but occasionally may have more aggressive and malignant girls under the age of 20 years. Most granulosa cell tumours secrete oestrogen which may Ovarian choriocarcinoma is more malignant than that of be responsible for precocious puberty in young girls, or in placental origin and disseminates widely via bloodstream older patients may produce endometrial hyperplasia, to the lungs, liver, bone, brain and kidneys.

Other Germ Cell Tumours Certain other germ cell tumours occasionally encountered Grossly, granulosa cell tumour is a small, solid, partly in the ovaries are embryonal carcinoma, polyembryoma and cystic and usually unilateral tumour. Thus, these include tumours originating from granulosa cells, theca cells and Sertoli-Leydig cells. Since sex cord-stromal cells have functional activity, most of these tumours elaborate steroid hormones which may have feminising effects or masculinising effects.

Well-differentiated androblastoma composed almost thecoma may secrete androgen and cause virilisation. Tumours with intermediate differentiation have a biphasic Microscopically, thecoma consists of spindle-shaped theca pattern with formation of solid sheets in which abortive cells of the ovary admixed with variable amount of tubules are present. Poorly-differentiated or sarcomatoid variety is composed rich and vacuolated which reacts with lipid stains. Mixture of both granulosa and theca cell elements in the same ovarian tumour Gynandroblastoma is seen in some cases with elaboration of oestrogen. Fibromas of the ovary are more common and there is combination of patterns of both granulosa-theca cell account for about 5% of all ovarian tumours. The term are hormonally inert but some of them are associated with gynandroblastoma stands for combination of female (gyn) pleural effusion and benign ascites termed Meigās syndrome. There is a small group of ovarian Histologically, they are composed of spindle-shaped well tumours that appears as soft yellow or yellow-brown nodules differentiated fibroblasts and collagen. Sometimes, which on histologic examination are composed of large lipid 750 Figure 24. These cells resemble Leydig, lutein and adrenal carcinomas of the breast, genital tract, gastrointestinal tract cortical cells. The tumour is exclusively in dysgenetic gonads, more often in phenotypic generally secondary to a gastric carcinoma (page 557) but females and in hermaphrodites. Rarely, a tumour having the pattern of Microscopically, gonadoblastoma is composed of mixture Krukenberg tumour is primary in the ovary. Cut section shows grey-white to yellow firm fleshy tumour and may About 10% of ovarian cancers are secondary carcinomas. Metastasis may occur by lymphatic or haematogenous route Microscopically, it is characterised by the presence of but direct extension from adjacent organs. It is accompanied by sarcoma-like cellular prolife Bilaterality of the tumour is the most helpful clue to diagnosis ration of ovarian stroma (Fig. Histologic features include mucin-filled signet-ring cells and richly cellular proliferation of the ovarian stroma. Certain conditions such as inflammation of the placenta and 751 ļµļµ chorionic membranes (placentitis and chorioamnionitis), Stage I Growth limited to ovaries. Hydatidiform mole is defined as an abnormal ruptured, or with ascites containing malignant cells. Pathogenesis of these 2 forms is different: At term, the normal placenta is blue red, rounded, flattened and discoid organ 15-20 cm in diameter and 2-4 cm thick. It Complete (classic) mole by cytogenetic studies has been weighs 400-600 gm or about one-sixth the weight of the shown to be derived from the father (androgenesis) and has newborn. Complete mole contains two umbilical arteries and one umbilical vein bears relationship to choriocarcinoma. Partial mole rarely develops into placenta has irregular grooves dividing it into cotyledons choriocarcinoma. The foetal portion of the placenta gestation and is characterised by increase in uterine size, is composed of numerous functional units called chorionic vaginal bleeding and often with symptoms of toxaemia. The Frequently, there is history of passage of grape-like masses villi consist of a loose fibrovascular stromal core and a few per vaginum. These include: human chorionic gonado complete mole develop into invasive moles and 2. The pathologic findings Diseases related to pregnancy and placenta are numerous in non-invasive (complete and partial) and invasive mole and form the subject matter of discussion in obstetrics. The specimen shows numerous, variable-sized, grape-like translucent vesicles containing clear fluid. Grossly, the uterus is Large, round, oedematous and acellular villi due to enlarged and characteristically filled with grape-like hydropic degeneration forming central cisterns. Rarely, a macerated foetus may Trophoblastic proliferation in the form of masses and be found. Clinical findings i) Diagnosis Mole Missed abortion Abortion; molar, ectopic or normal pregnancy ii) Vaginal bleeding Marked Mild Marked, abnormal iii) Uterus size Large Small Generally not bulky 3.

Persistence after initial 20% 7% May metastasise rapidly therapy if not treated 8. Behaviour 2% may develop Choriocarcinoma almost Survival rate with choriocarcinoma never develops chemotherapy 70% 753 Figure 24. A foetus with multiple Widespread haematogenous metastases are early and malformations is often present. Masses and columns of highly anaplastic and bizarre Microscopically, the lesion is benign and identical to cytotrophoblast and syncytiotrophoblast cells which are classic mole but has potential for haemorrhage. Gestational choriocarcinoma is a highly malignant and widely metastasising tumour of trophoblast (non-gestational Gestational choriocarcinoma and its metastases choriocarcinoma is described on page 748). Approximately respond very well to chemotherapy while non-gestational 50% of cases occur following hydatidiform mole, 25% choriocarcinoma is quite resistant to therapy and has following spontaneous abortion, 20% after an otherwise worse prognosis. With hysterectomy and chemotherapy, normal pregnancy, and 5% develop in an ectopic pregnancy. Death Clinically, the most common complaint is vaginal from choriocarcinoma is generally due to fatal bleeding following a normal or abnormal pregnancy. Each lactiferous duct has the breast is a modified skin appendage which is functional its own collecting duct system which has branches of smaller in the females during lactation but is rudimentary in the diameter, ultimately terminating peripherally as terminal males. In a fully the entire ductal-lobular epithelial system has bilayered developed non-lactating female breast, the epithelial lining: the inner epithelium with secretory and absorptive component comprises less than 10% of the total volume but function, and an outer supporting myoepithelial lining, both is more significant pathologically since majority of lesions having characteristic ultrastructure and immunoreativity. The supportive stroma of the during lactation, and large duct system which performs the breast consists of variable amount of loose connective tissue function of collection and drainage of secretions; both are and adipose tissue during different stages of reproductive interconnected to each other. The stromal tissue of the breast is present at 2 locations: the breast is divided into about 20 lobes. Intralobular stroma consists of breast lobules which drain their secretions through encloses each lobule, and its acini and ducts, and is chiefly its collecting duct system and opens into the nipple through made of loose connective tissue, myxomatous stroma and a its own main excretory duct, lactiferous duct. Mammary duct ectasia is a condition in which one or more the most important disease of the breast is cancer. These are associated with periductal tumours and tumour-like lesions which may be confused and interstitial chronic inflammatory changes. These conditions in the breast include inflammations, the etiology of the condition remains unknown but it fibrocystic change and gynaecomastia. Grossly, the condition mastitis, mammary duct ectasia (or plasma cell mastitis), appears as a single, poorly-defined indurated area in the traumatic fat necrosis and galactocele. Acute Mastitis and Breast Abscess Histologically, the features are as under: Acute pyogenic infection of the breast occurs chiefly during 1. Dilated ducts with either necrotic or atrophic lining the first few weeks of lactation and sometimes by eczema by flattened epithelium and lumen containing granular, of the nipples. Periductal and interstitial chronic inflammation, cracks and fissures in the nipple. Initially a localised area chiefly lymphocytes, histiocytes with multinucleate histio of acute inflammation is produced which, if not effectively cytic giant cells. Sometimes, plasma cells are present in treated, may cause single or multiple breast abscesses. Occasionally, there may be obliteration of the ducts by fibrous tissue and varying amount of inflammation and Granulomatous Mastitis is termed obliterative mastitis.
