The requirements of these condensed premedical science subjects are very rigorous, thus preparation prior to the beginning the General Medicine, Dentistry or Pharmacy Program is recommended. Students successfully completing the course are directly admitted to their chosen program. Students are encouraged to ask questions related to the topic of the lectures discussed, and participate in solving problems related to the topic of the seminar. Some professors will ask for students to volunteer information, but some professors call on students randomly. It is, thus, a good idea to come to class prepared so as not to be embarrassed in front of the class. The usage of electronic devices, textbooks and any form of interaction between students during the tests is strictly forbidden. Violation of these above mentioned regulations results in an immediate and unconditional dismissal from the program. Attending lectures is strongly recommended, attendance of seminars is compulsory and recorded. Everyone must attend the seminars with the group designated by the Registrar’s Office. Absence can significantly affect your understanding and can have serious implications for progression in your studies. One might have a maximum of six seminar absences to have the opportunity to get exemption. Missed seminars cannot be made up unless one obtains prior permission to be absent. Self Control Tests, End of Semester Exams, and Final Exams will be assessed as follows. Lecture: Nucleic acids and the origin of life Proteins, carbohydrates and lipids 2.

A credit is a relative index of cumulative work invested in a compulsory, a required elective or a freely chosen subject listed in the curriculum. The credit value of a course is based upon the number of lectures, seminars and practical classes of the given subject that should be attended or participated in (so called "contact hours"), and upon the amount of work required for studying and preparing for the examination(s).
Steroids and immunoglobulin replacement may be used in patients with autoimmune cytopenias or symptomatic hypoglobulinemia (respectively) 250 mg cefadroxil overnight delivery antimicrobial breakpoints. Of the choices given buy cefadroxil 250 mg amex bacteria 5 kingdoms, squamous cell carcinoma is the likeliest expla- nation for this patient’s hemoptysis. Bronchoscopy would likely show the lesion and allow a tissue diagnosis to be made. Adenocarcinoma of the lung is the commonest lung cancer seen in nonsmokers, women, and younger patients. Its incidence is increased in smokers (probably twofold), but not to the degree seen with squamous cell carcinoma and small cell undiffer- entiated carcinoma. Adenocarcinoma is typically peripheral with pleural involvement (rather than the central involvement seen in this case). Bronchoalveolar cell carcinoma arises from alveolar epithelium, is typically peripheral, and may resemble a nonhealing pneumonia (it may even have air bronchograms like a pneumonia). Bronchial adenomas (carcinoid being the commonest type) are often central but are usually smaller and are less common than squamous cell carcinomas. If all three elements (red blood cells, white blood cells, and platelets) are affected, the cause is usually in the bone mar- row (although peripheral destruction from hypersplenism can occasionally cause pancytopenia). In this patient without a history of liver disease or palpable splenomegaly on physical examination, a bone marrow produc- tion problem is the most likely culprit. Although B12 deficiency can cause pancytopenia, usually a macrocytic anemia is the most prominent feature; a serum B12 level would be reasonable, but the most productive approach would be to examine the bone marrow. Leukemia can present without leukocytosis (so-called aleukemic leukemia), but the most likely diagnosis would be aplastic anemia. Pelvic full- ness, vague discomfort, constipation, and early satiety are often the first symptoms of this disease. If the pelvic exam and ultrasound were negative, sigmoidoscopy might be indi- cated to evaluate the patient’s constipation. Pregnancy decreases the risk of ovarian cancer; each pregnancy decreases the risk by about 10%. A family history of ovarian cancer is a major risk factor, increasing a woman’s risk threefold. Coitus early in life and multiple part- ners are risk factors for cervical, but not ovarian, carcinoma. Many patients present with a hematuria or flank pain, but the classic triad of hematuria, flank pain, and a palpable flank mass occurs in only 10 to 20% of patients. Paraneoplastic syndromes such as erythrocytosis, hypercalcemia, hepatic dysfunction, and fever of unknown origin are common. Surgery is the only potentially curable therapy; the results of treatment with chemotherapy or radiation therapy for nonre- sectable disease have been disappointing. Interferon α and interleukin 2 produce responses (but no cures) in 10 to 20% of patients. Radiation therapy is used in metastatic renal carcinoma, but results are disappointing. Immunotherapies such as interferon and interleukin 2 have been used for palliation. Palpation of the scrotal mass and transillumination (holding a flashlight directly against the posterior wall of the scrotum) will distinguish testicular lesions from other masses within the scrotum, such as hydrocele. The lymphatic drainage of the testis is into the periaortic nodes, not to the inguinal nodes. Although benign causes (prostatitis, renal stones) are most common, as many as 30% of patients with gross hematuria will have malignancies of the genitourinary tract. Exposure to ani- line dyes, chronic cyclophosphamide treatment, external beam radiation, and Schistosoma infection of the bladder are other risk factors. This patient should be referred to a urologist for cystoscopy to rule out transitional cell carcinoma of the bladder. Although infectious mononucleosis and toxoplasmosis can cause diffuse lymphadenopathy, these infections are usually associated with other evidence of infection such as pharyngitis, fever, and atypical lymphocytosis in the peripheral blood. It would be unusual for the lymph- adenopathy associated with these infections to persist for 2 months. Serum 186 Medicine angiotensin converting enzyme level is a nonspecific test for sarcoidosis but is also elevated in other granulomatous diseases and is not sensitive or spe- cific enough to be used as an initial diagnostic test.
