The primary change in this condition is simple dilatation of the larger periareolar ducts associated with periductal inflammation order cialis with visa erectile dysfunction videos. Due to leakage of the secretion through the damaged duct walls buy discount cialis 10 mg erectile dysfunction treatment philippines, there may be an irritant reaction in the tissues around the ducts leading to periductal mastitis. Such periductal mastitis produces a painful mass or even a frank periareolar abscess. Repeated inflam­ matory processes cause fibrosis, nipple retraction and even fistula formation. As to the pathogenesis of this condition is concerned, the sole question is ‘what does cause the initial duct dilatation? The pathologists who contradict these theories suggest (iv) that the periareolar inflammation is the primary pathogenic process. The lump is mostly beneath the areola, occasionally peripheral lump may be present. Classically it is thick and creamy but sometimes greenish discharge may be present. This condition may even produce bloody discharge where no other cause such as papilloma can be detected. The disease is usually unilateral but may involve the other breast within a few years. If there is a solitary duct fistula, fistulectomy with excision of the involved duct should be considered. The patient may fear cancer and the discharge itself causes annoyance and social embarrassment. In the history the patient should be questioned whether the discharge is unilateral or bilateral, whether it is associated with a lump or not, or whether the discharge is blood stained or not. On inspection, one may detect the duct or ducts from where the discharge is coming out. Excessive crusting may occasionally be seen on the nipple which is nothing but dried product of secretion. On palpation, the whole breast is examined with particular attention towards the subareolar region. On mammography the most important feature to be noticed is the intraductal microcalcification of carcinoma in situ. In neonates a milky nipple discharge may occur transiently due to transplacental passage of luteal hormones from the mother’s circulation. It may be seen at menarche and menopause and even may occur years after cessation of breast feeding. In these physiological circum­ stances simple reassurance is all that is required. Hyperprolactinaemia due to a prolactin-secreting tumour or from a secondary source of bronchogenic carcinoma may cause galactorrhoea. Fibrocystic disease or cystic mastopathy typically produces multiple-duct discharge and is another commonly associated disease. It must be remembered that multiple papillomas particularly occurring in the periphery of the breast involving more than one duct carry an increased risk of malignant change. These peripheral lesions are more likely to cause a breast mass than nipple discharge. After thorough investigations if no cause can be found out simple reassurance is enough for serous or watery or non­ blood-stained discharges. If the discharge is blood-stained, it should be assumed that the cause is there, but not detected. Though the ductal system of the breast is continuously secreting fluid under normal circumstances, yet it is uncommon for women to notice any discharge through the nipple. Only in extremely rare cases due to excessive physiological activity nipple discharge may be noticed in the second phase of menstrual cycle. Lactation may continue for months or years after suckling if the patient continues to express milk because she thinks this should be done. Drugs including the contraceptive pills may occasionally lead to slight discharge of milk perhaps through pituitary prolactin mechanism. Milk discharge may be seen in case of milk fistula following chronic subareolar mastitis. Serous discharge may be seen in cases of fibroadenosis and mammary duct ectasia, though greenish-black discharge is more common in fibroadenosis and thick creamy discharge is more often seen in mammary duct ectasia. Duct papilloma and non-infiltrating duct carcinoma may produce serous discharge in the intervals of bloody discharge. Non-infiltrating or infiltrating type of duct carcinoma may cause blood stained discharge which are more commonly seen after the age of 50 years. Similar coloured fluid can also be obtained from cyst aspiration in similar cases. Serous, brownish or even greenish discharge may also be found in mammary duct ectasia. But if the discharge continues and is proving intolerable, microdochectomy should be performed. When the duct cannot be located, cone excision of the major ducts (Hadfield’s operation) should be performed. Galactorrhoea if caused by mechanical stimulation and ingestion of the drugs, these should be stopped. In other cases prolactin level should be detected and if the level is normal, simple reassurance should be given. If it is due to prolactin-secreting tumour or from bronchogenic carcinoma these should be treated. So it is the treatment of choice in case of young women with single duct discharge. A stiff nylon suture or a fine probe is inserted into the duct from which the discharge is coming out and is fixed to the skin of the nipple with fine silk stitches. With a pair of fine-pointed scissors a triangular area is cut 1 mm away from the point of entry of the stiff nylon. With fine-pointed scissors the breast tissue alongwith the duct is dissected off to reach the depth. The specimen of duct alongwith the triangular skin is removed intact including the stiff nylon. With blunt dissection a plane of cleavage is dissected circumferentially around the terminal lactiferous ducts. Once the ducts are dissected out they are divided close to the nipple and are removed with a conical wedge of tissue with long axis of 2 to 4 cm and with the base of 1 to 2 cm of the subareolar tissue. Any opened ducts are closed by ligature and the cavity in the breast substance is obliterated with deep sutures. The wound is closed with 3/0 subcuticular dexon suture with a small vaccuum drain. Nipple inversion means congenital failure of eversion of nipple during development. Nipple retraction means a secondary process in which the nipple is retracted, which was normal before.

Rarely purchase 10 mg cialis free shipping erectile dysfunction urology tests, a syndrome of “leukostasis” can occur when the white cell count is extremely elevated order 20 mg cialis mastercard erectile dysfunction treatment in vijayawada. This results from sludging of the leukemic cell in the vasculature, resulting in headache, dyspnea, confusion, and brain hemorrhage. In about 10% of acute leukemias, depression of all 3 cell lines is evident (aleukemic leukemia). None of these will have leukemic blasts circulating in the peripheral blood, however. A bone marrow biopsy showing >20% blasts confirms the diagnosis of acute leukemia. The presence of blasts tells you the patient has acute leukemia, but blast analysis cannot be relied upon to always tell which type is present. This is followed by further rounds of chemotherapy to “consolidate” the leukemia further. Leukostasis events are managed with leukapheresis in addition to the chemotherapy. Although the Philadelphia chromosome is characteristic of the disease, the cause of the production of this chromosome is unknown. The Philadelphia chromosome is a translocation between chromosomes 9 and 22, resulting in a gene producing an enzyme with tyrosine kinase activity. Infection and bleeding are uncommon because these white cells retain the majority of their function. Rarely, a leukostasis reaction can occur from extremely elevated amounts of white cells being produced in the range of 3 200,000–500,000/mm. The white cells then clog up the vasculature, resulting in dyspnea, blurry vision, priapism, thrombosis, and stroke. The main feature of the disease is an elevated white blood cell count consisting predominantly of neutrophils with a left shift. Although the B12 level is often elevated, this would not be enough to establish the diagnosis. Imatinib is a direct inhibitor of the tyrosine kinase produced by the Philadelphia chromosome. There is nearly a 90% hematologic response to imatinib, and as many as 60 to 70% of patients may lose the Philadelphia chromosome. This is because of the extraordinary response to imatinib, as well as the high mortality associated with the bone marrow transplantation itself. When patients do have symptoms, they are often nonspecific—fatigue, lethargy, and uncomfortable enlargement of lymph nodes. Infiltration of other parts of the reticuloendothelial system such as the spleen, liver, and bone marrow also occurs. The cell count is usually elevated in the range of 30,000–50,000, but may go as high as 150,000. Those with more advanced-stage disease should receive initial therapy with fludarabine. Fludarabine has greater efficacy than chlorambucil and should be considered the drug of choice. The malignant B lymphocytes (“hairy cells” ) accumulate in the bone marrow, interfering with the production of normal cells commonly causing pancytopenia. Bone marrow failure is caused by the accumulation of hairy cells and reticulin fibrosis in the bone marrow, as well as by the unfavorable effects of dysregulated cytokine production. For cladribine-resistant disease, consider monoclonal antibodies (rituximab most common) which destroy the malignant B cells. Alpha interferon is helpful in 60% of patients to stabilize the disease or produce a slow, minor improvement. More than 95% of new patients are treated well or at least adequately by cladribine or pentostatin; most can expect a disease-free remission time span of 10 years or even longer after taking one of these drugs just once. By definition, you must exclude B12 and folate deficiency because the disorder is so similar. You may find a bi-lobed neutrophil called a Pelger-Huet cell which is characteristic. Some patients who are young enough with a match can undergo bone marrow transplantation. Red cells are produced in excessive amounts in the absence of hypoxia or increased erythropoietin levels. Patients present with: Markedly elevated hematocrit Splenomegaly Sometimes elevation of the platelet and white cell counts Thrombosis “Plethora” or redness and fullness of the face Pruritis (approximately 40% of patients), particularly after exposure to warm water such as in a shower or bath; possibly caused by abnormal histamine or prostaglandin production Diagnosis. Diagnose with a high hematocrit in the absence of hypoxia, carbon monoxide poisoning, or elevated erythropoietin level. Treatment: Phlebotomy is the primary treatment; hydroxyurea may be used in addition to or as an alternative. The disease is characterized by various systemic manifestations such as bone, kidney, and infectious complications. Bone pain is the most common clinical manifestation, usually in the back and the ribs, secondary to pathologic fractures. Infection particularly with encapsulated organisms such as Pneumococcus and Haemophilus is common. The symptoms of hypercalcemia such as polyuria, polydipsia, and altered mental status may occur. Rarely, symptoms of a hyperviscosity syndrome such as blurry vision, confusion, and mucosal bleeding may occur. Although a normochromic, normocytic anemia is the most common laboratory finding, this is not specific for myeloma. A protein electrophoresis with a markedly elevated monoclonal immunoglobulin spike is present in almost all cases. This is most commonly IgG but may be IgA, IgD, or rarely a combination of two of these. In about 80% of individuals, routine x-ray will reveal the punched-out lytic lesion caused by the overproduction of osteoclast activating factor from the plasma cells and/or pathologic fractures at the time of diagnosis. Most commonly involved are the vertebrae, ribs, pelvic bones, and bones of the thigh and upper arm. A bone marrow biopsy with >10% plasma cells confirms a diagnosis of multiple myeloma. Bence-Jones protein is often not detected by a standard protein test on a urinalysis, which mainly is meant to detect albumin. A specific test for Bence- Jones protein involving acidification of the urine is required. Increased gamma globulin levels will increase the total protein and decrease the albumin level. Younger patients (age <70) should be treated with autologous bone marrow transplantation in an attempt to cure the disease. Patients who are candidates for transplants should receive thalidomide (or lenalidomide) and dexamethasone.

The indications of such operation are — (i) Stone with pyonephrosis when the patient is too ill to stand any other operation buy cialis visa safe erectile dysfunction pills. This operation has been described in detail in ‘A Practical Guide to Operative Surgery’ purchase genuine cialis erectile dysfunction treatment in vadodara. Usually the kidney with the better function is operated on first and the operation on the contralateral side is postponed for no less than 2 months to allow adequate time for the first kidney to recover. If the kidneys are without infection or without any symp­ tom and particularly, if the patient is elderly it is probably better to avoid any operation. The main disadvantage is that the access is limited being bounded above by the last rib and below by the iliac crest. Position of the patient — The patient lies on his sound side with its back brought well over towards the edge of the table. The loin overlies the bridge of the table, which can be screwed up to increase the space between the costal margin and the iliac crest. To maintain the stability of this position, the lower hip and the knee are kept flexed and the upper leg is extended over them. Sand-bags are kept in position with a wide strapping to prevent the patient from rolling over. The upper arm is supported on an arm rest to prevent the shoulder from sagging forwards and to relieve the chest of compression by the weight of the arm. In case of obese patients or when a large kidney has to be operated on, the incision can be extended forwards as far as the lateral border of the rectus muscle. The lower fibres of the latissimus dorsi are cut along the line of the incision and while this incision is extended forwards, it cuts the most superficial i. The incision is now deepened at its highest part cutting another muscle — serratus posterior- inferior, to expose the lateral border of the quadratus lumborum with the lumbar fascia starting from its lateral margin. The anterior part of the incision is now deepened and one of the two muscles internal oblique cut along the line of the incision to protect the peritoneum from being incised. The neurovascular bundle comprising the 12th thoracic nerve and accompanying subcostal vessels are found passing downwards and forwards within the deeper layers of the internal oblique at right angle to its fibres. The lumbar fascia is now incised just in front of the lateral border of the quadratus muscle to expose the retro-peritoneal fat. Two fingers are inserted through this opening and used to separate the peritoneum from the under-surface of the transversus muscle. As this separation continues with one hand, the transversus muscle is divided with a pair of scissors throughout the extent of the incision. So five muscles are incised for this exposure :— Latissimus dorsi and serratus posterior-inferior posteriorly and the three lateral muscles of the abdominal wall anteriorly. To do this, the quadratus lumborum and associated fascia are detached form its lower border. By a little gauze dissection, the renal fascia is identified in the posterior part of the wound. This incision on the fascia is extended anteriorly as fas as required but care should be taken to safeguard the peritoneum in the anterior part of the wound. In the upper pole, the kidney may be anchored by fibrous bands which traverse from the capsule of the kidney to the diaphragm. The adrenal gland is carefully separated by the dissecting finger from the kidney. On the anterior surface of the kidney the peritoneum is adherent and must be detached with care. Other adhesions, if there be any, should be looked for and divided to mobilise the kidney properly. Care should be taken to include all the muscles which have been divided Drainage of the retro-peritoneal space should be provided either by a corrugated rubber sheet or by a suction drainage (Redi-vac). In case it happens, a water-seal drainage should be introduced through the 10th inter space and the pleura is closed. The incision starts a little medial to the lateral border of the erector spinae muscle at the level of the 12th rib. The incision is carried forwards along the line of the 12th rib and is continued beyond its tip as far as required. The Latissimus dorsi and serratus posterior-inferior are come across in the medial part of the wound and these are divided. The bed of the rib comprising of the periosteum and the fibres of the diaphragm are cautiously incised to get into the retro-peritoneal space. The lower reflection of the pleura is identified at the medial part of this incision and is carefully pushed upwards. The incision along the 12th rib is carried forward into the loin, while the medial end of this incision is extended upwards vertically upto just above the neck of the 10th rib. The upper vertical portion is deepened and 2 to 3 cm segments ofthe 11th and 10th rib are excised. This approach will give a very wide exposure, highly suitable for upper pole tumours. In case of hypernephroma, intra-peritoneal approach is preferred as the extent of the growth along the renal vein to the inferior vena cava is assessed and the renal vein is first ligated before the hypernephroma is mobilised. A long upper paramedian incision with a transverse extension at the level ofthe umbilicus, dividing the rectus and the lateral abdominal muscles is mostly employed. The peritoneum on the posterior wall is incised along the lateral side of the flexure of the colon. The colon is then mobilised and displaced medially to expose the anterior surface of the kidney and its vessels. At the end of the operation the peritoneum which was incised is sutured back and the retro-peritoneal space is drained through the loin. Gravity and peristalsis both contribute to spontaneous passage into and down the ureter. Stones with other composition have smooth surfaces and are often passed through the ureter without being impacted. A ureteral stone is only detected when it causes some symptoms due to its presence in the ureter or any pathological changes to the kidney or ureter. If the stone remains for weeks or months irrepa­ rable damage to the renal parenchyma may occur. There are 3 sites of anatomical narrowing of the ureter where a stone may be arrested. These are — (i) pelviureteral junction, (ii) when the ureter crosses the iliac artery and (iii) where it enters through the bladder wall. Occasionally a stone may remain lodged in a ureter for many months without harming the kidney. When the stone has impacted patient may complain of dull ache which gets worse during walking and exercise. Pyelitis, pyelonephritis and pyonephrosis (from hydronephrosis) may occur due to infection.

The tuberculous sinus will reveal its characteristic features like undermined edge and bluish margin cheap generic cialis uk erectile dysfunction treatment, whereas in chronic pyogenic osteomyelitis there will be sprouting granulation tissue which indicates presence of sequestrum at the depth purchase cialis 5 mg free shipping erectile dysfunction most effective treatment. There may be paresis neous veins in case of osteo- due to involvement of the nerves by the bony swellings. Sometimes acute osteomyelitis may destruct the epiphyseal cartilage thereby hampering the growth of that particular bone. Genu valgum or genu varum may be the result of asymmetrical destruction of the lower epiphyseal cartilage of the femur. Shortening or lengthening of the bone — may sometimes be seen following infection of the bone which either provokes the growth of the bone or destroys the epiphyseal cartilage and hence retards the growth of the bone. In osteosarcoma the consistency varies — somewhere bony hard, somewhere firm and may be even soft at places. Being a bony swelling its consistency should also be bony hard, but the condition is so painful and tender that the clinician hardly reaches the bone during palpation and can only palpate the soft tissues overlying the bone which pits on pressure. Telangiectatic osteosarcoma, aneurysmal bone cyst, occasionally highly vascular osteoclastoma, very rarely haemangioma of bone and highly vascular metastatic carcinomas from thyroid cancer and renal adenocarcinoma. Note the foot drop on the right side due to involvement of the lateral popliteal nerve by an osteoma at the head of the fibula. These are commonly seen in chronic pyogenic osteomyelitis and tuberculous osteomyelitis. In case of the former there will be sprouting granulation tissue at the orifice of the sinus indicating presence of sequestrum in the depth and in case of the latter the ulcer will be undermining with bluish newly growing epithelial edge. In fact sometimes this fracture becomes the first presenting symptom of the primary carcinoma which may be in the lung, kidney, breast, prostate, thyroid etc. Shortening will be found when the epiphyseal cartilage is destroyed and the bone may be lengthened when the metaphysis is included within the zone of hyperaemia. Osteosarcoma, which mainly starts from the metaphysis, does not invade the epiphyseal cartilage until late and hence the joint remains unaffected. Swellings of the distal limb and venous engorgement may be due to pressure on the neighbouring veins. In tuberculous osteomyelitis general examination must be made to exclude pulmonary tuberculosis and lymphadenitis. Enquiry must be made whether the patiert had cough, evening rise of temperature, pain in the chest, haemoptysis, etc. In syphilitic osteitis, one should look for other syphilitic stigmas in the body (See Fig. In osteomyelitis a search should be made for infective foci in the skin, tooth, tonsil, ear, air sinuses, etc. Diaphyseal (metaphyseal) aclasis, generalized osteitis fibrosa, multiple myeloma are the examples of this condition. So the patient must be asked if there is any other bony swelling in his body or not. In secondary carcinoma a thorough examination must be made to exclude primary carcinoma in the thyroid, kidneys, lungs, prostate, breasts, uterus, gastrointestinal tract, testis, etc. There will be hyperproteinaemia, the globulin (particularly gamma globulin) being raised, (c) A rise in serum calcium indicates generalized osteolysis (which is seen in cases of hyperparathyroidism, metastatic bone tumours, multiple myeloma, sarcoidosis etc. Bence Jones protein may also be found in cases of skeletal carcinomatosis, leukaemia and rarely in nephritis. In chronic osteomyelitis, a dense sequestrum and surrounding involu- crum may be noticed. Density of the seques­ trum is due to decreased mobilization of calcium from decreased blood supply, whereas in involucrum calcium deposition has just commenced. This is revealed in X-ray by an osteolytic lesion affecting the FiS11 16 - Osteosarcoma showing the typical radiating lateral condyle of the tibia (indicated by spicule type. Osteoid osteoma is seen as a radiolucent nidus with a surrounding zone of bony sclerosis. In chondroma, whether enchondroma or ecchondroma, X-ray shows an osteolytic lesion with demarcated outline. The metaphysio-epiphyseal areas are seen to be enlarged and occupied by a cystic tumour. The cortex is thin with a sharp line of demarcation between the tumour and the unaffected shaft in contradistinction to the sarcomas. The expanding osteolytic lesion can continue to destroy the cortex, although usually it leaves some external rim. The cavity is traversed by bony trabeculae giving mosaic or soap-bubble appearance. Mostly the tumour grows eccentrically, often destroys the epiphyseal cartilage and it may penetrate the articular cartilage. This tumour expands transversely whereas a bone cyst expands along the long axis of the bone. X-ray appearance of osteosarcoma shows a combination of bone destruction and bone formation. Three types are commonly seen — (i) Sclerotic type, usually found at puberty, shows dense new irregular bone with a few spicules projecting from its surface in the metaphysis. The periosteum may show sun-ray spicules due to calcification along the blood vessels supplying the raised periosteum. In bone sarcoma there is always the soft tissue shadows in the skiagram due to increased vascularity of the tumour. Chondrosarcoma in skiagram shows frank destruction of the trabecular bone and cortex with an expanding lesion which contains irregular flecking and the mottling of calcified tissue. At least 50% of medulla must be destroyed before a lesion will be seen radiologically. Osteolysis without formation of new bone is the feature except in carcinoma of the prostate where Fig, 11. In Paget’s disease the bone as a whole is thick and bent; its density in the vascular stage is decreased and in the sclerotic stage increased. In Osteitis fibrosa (Hyperparathyroidism; Von Recklinghausen’s disease) skiagram shows a mixture of osteoporosis, cystic changes and coarsening of the trabecular pattern. Cysts may extend beyond the confines of the long bones and there may be subperiosteal erosions of the cortex. There may be even disappearance of the terminal outline with only longitudinal trabeculae remaining. In Multiple myeloma circumscribed areas of rarefaction affect the different bones, which may mimic secondary metastasis. All these features may not be present simultaneously in all primary malignant tumours, but one or the other change will be obvious.
