This is followed in patients < 60 years with radiotherapy.The mainstay of definitive therapy is chemotherapy.A single dose of rituximab is generally administered prior to cytotoxic chemotherapyChemotherapy includes high-dose methotrexate, but multi agent chemotherapy, usually adding vincristine and procarbazine, appears to be more effective than methotrexate alone.Chemotherapy is followed in patients <60 years with whole-brain radiation therapy (WBRT).Despite aggressive therapy >90% of patients develop recurrent CNS disease."}

Before reading about the types of error you must know null hypothesis because these tests are related to null hypothesis. Null hypothesis says - Any kind of difference or significance you see in a set of data is due to chance and not significant that means there is no variation (difference) exists between variables. Null hypothesis testing (e.g., in Chisquare test) is used to make a decision about whether : - i) The data contradict the null hypothesis - That means there is true difference (which is significant) between variables and it is not due to chance. Or ii) The data approve the null hypothesis There is no difference between variables and the difference you see is due to chance. Now see types of error :? There are two basic type of statistical errors : ? Type I error Type II error Type I error It is also known as an error of first kind or a-error or false positive. This type of error rejects null hypothesis when it is true - False rejection of null hypothesis. That means in real there is no difference (as null hypothesis says) but we observe a difference (by rejecting the null hypotesis due to error). In very simple words \"we observe a difference when it is not true\" - false positive. One of the simplest example of this would be if a test shows that a women is pregnant when in reality she is not, i.e., she is false positive for pregnancy. Probability of type-I error is given by 'P-value' (probability of declaring a significant difference when actually it is not present). Significance (a) level is the maximum tolerable probability of type I error. Significance (a) level is fixed in advance and calculation of P value (probability of type I error) can be less than, equal to or greater than the significance (a) level. If the probability of type I error (P -value) is less than significance (a) level, the results are declared statistically significant. Therefore, to declare the results statistical significant, type I error (a-level) should be kept to minimum . Type I error is more serious that type II error. Type II error It is also known as an error or second kind or A-error or false negative. This type of error accept/fail to reject the null hypothesis when it is false False acceptance of null hypothesis. That means we fail to observe a difference when in truth there is one - False negative. An example of this would be if a test shows that a woman is not pregnant when in reality she is i.e., she is false negative."}

It is a major agent of schistosomiasis; more specifically, it is associated with urinary schistosomiasis. Adults are found in the Venous plexuses around the urinary bladder and the released eggs traverse the wall of the bladder causing haematuria and fibrosis of the bladder. The bladder becomes calcified, and there is increased pressure on ureters and kidneys otherwise known as hydronephrosis. Inflammation of the genitals due to S. haematobium may contribute to the propagation of HIV. Studies have shown the relationship between S. haematobium infection and the development of squamous cell carcinoma of the bladder Life cycle The female fluke lays as many as 30 eggs per day which migrate to the lumen of the urinary bladder and ureters. The eggs are eliminated from the host into the water supply with micturition. In fresh water, the eggs hatch forming free swimming miracidia which penetrate into the intermediate snail host (Bulinus spp., e.g. B. globosus, B. forskalii, B. nyassanus and B. truncatus). Inside the snail, the miracidium sheds it epithelium and develops into a mother sporocyst. After two weeks the mother begins forming daughter sporocysts. Four weeks after the initial penetration of the miracardium into the snail furcocercous cercariae begin to be released.

Which of following is the clinical diagnosis -\nA) Appendicitis\nB) Leukemic colitis\nC) Perforation peritonitis\nD) Neutropenic colitis", "output": "3, because Neutropenic enterocolitis (NE) is also known as typhlitis, ileocecal syndrome, cecitis, or necrotizing enterocolitis. Despite the previous use of the term \"necrotizing enterocolitis\" to describe NE cases, necrotizing enterocolitis is a different inflammatory illness seen in newborns and is beyond the scope of this review. NE is a clinical entity initially described in leukemic pediatric patients. It has also been repoed in adults with hematologic malignancies such as leukemia, lymphoma, multiple myeloma, aplastic anemia, and myelodysplastic syndromes, as well as other immunosuppressive causes such as AIDS, therapy for solid tumors, and organ transplant. The true incidence of NE is unknown. One systematic review published in 2005 suggested a pooled incidence of 5.6% in hospitalized adults with hematological malignancies, chemotherapy for solid tumors, and aplastic anemia. The repoed moality also varies with rates as high as 50%. NE was repoed initially after the use of taxane drugs, but more recently an increasing number of chemotherapeutic drugs have been implicated. Other drugs linked to NE include cytosine arabinoside, gemcitabine, vincristine, doxorubicin, gemcitabine, cyclophosphamide, 5-fluorouracil, leuvocorin, and daunorubicin. Immunosuppressive therapy for organ transplant, antibiotics, and sulfasalazine for the treatment of rheumatoid ahritis have also been considered causes of NE. PATHOGENESIS The exact pathogenesis of NE is not completely understood. The main elements in disease onset appear to be intestinal mucosal injury together with neutropenia and the immunocompromised state of the afflicted patients. These initial conditions lead to intestinal edema, engorged vessels, and a disrupted mucosal surface, which becomes more vulnerable to bacterial intramural invasion. Chemotherapeutic agents can cause direct mucosal injury (mucositis) or can predispose to distension and necrosis, thereby altering intestinal motility. Cytosine arabinoside (cytarabine) is a chemotherapeutic agent used to treat leukemia and lymphoma that is paicularly associated with the development of NE. Intestinal leukemic infiltration is another potential factor in the pathogenesis of NE, which may explain the presence of acute myelogenous leukemia presenting as NE before the onset of chemotherapy regimens Ref Davidson edition23rd pg 836"}

The symptoms are usually brought on by head movement. The cause is commonly attributed to calcium debris in the semicircular canals, known as canalithiasis. The debris is loose otoconia (calcium carbonate) within the utricular sac. Although BPPV can occur after head trauma, there is usually no obvious precipitating factor. It generally abates spontaneously and can be treated with vestibular rehabilitation. Basilar migraine can cause vertigo, but it is not brought on by movement, there is an associated headache and lasts longer than the 30 seconds noticed in this patient. Brainstem ischemic events or cerebellar tumors can cause vertigo but the symptoms are persistent and not intermittent.

In situ tumours usually retain CDH1production, whereas loss of CDH1 production due to down-regulation or occasional mutational inactivation of CDH1 hasbeen observed in human cancers, suppoing the theory thatCDH1 plays a key role in suppression of invasion and metastasis.Cross-talk between cancer cells and cells of the surroundingstromal tissue is involved in the acquired capability for invasivegrowth and metastasis. Mesenchymal stem cells in tumourstroma have been found to secrete CCL5, a protein chemokinethat helps recruit leucocytes into inflammatory sites. With thehelp of paicular T-cell-derived cytokines (interleukin (IL)-2and interferon-gamma (IFN-g)), CCL5 induces proliferation andactivation of natural killer cells and then acts reciprocally oncancer cells to stimulate invasive behaviour. Macrophages atthe tumour periphery can foster local invasion by supplyingmatrix-degrading enzymes such as metalloproteinases andcysteine cathepsin proteases.The lungs, liver, brain, and bones are the most common metastasis locations from solid tumors.
