Oral contraceptives have been implicated as a causative factor of venous thrombosis and thromboembolism. Compounds containing over 50 mcg of estrogen have developed this complication most frequently. Steroid hormones have a marked influence on liver function. Large doses have caused cholestasis and hepatocellular damage. Disturbances in carbohydrate metabolism have been recorded. Lipid metabolism have also been shown to be disturbed with increased serum levels of triglycerides and low density lipoproteins. A rise in the cholesterol serum level seems to be correlated with the progestogen content of the compound. The ''minipill'' with a small dose of progestogen alone had been effective by alteration of the cervical mucus. The ''one-a-month pill'' is a combination of a long-acting estrogen, quinestrol, and a chorter acting progestogen, qunigestanol acetate. It has not been as acceptable or as effective as combined compounds. The ''morning-after'' pill consists of large doses of stilbestrol. The method has been effective but when de-ethylstilbestrol has been given to a patient already pregnant to prevent an early spontaneous abortion, adenocarcinoma of the cervix or vagina has been reported. Hypertension has been more common with increased duration of pill use. High dosage of progestogens and increasing age of patients have increased the incidence of hypertension. Cerebrovascular disease had also been more frequent among pill users. An increased incidence of gallbladder disease and of gallstones has been shown in pill users. Urinary tract and vaginal infections were reported more often in pill users. Increased sexual activity may have been a factor in this relationship. Resumption of ovualation after discontinuation of oral contraceptives usually follows within 4-6 weeks. In about 1% of patients amenorrhea and anovulation result for 6 months or more. This is often accopanied by galactorrhea. There is evidence that mestranol is demethylated to ethinyl estradiol in the liver. Progesterone seems to interfere with conversion. Therefore ethinyl estradiol is preferred as a compound of the pill. Also the different progestogens used are metabolized in the liver to norethisterone before they exert their biological effects. Several drugs, as ampicillin and barbiturates, have been shown to interfere with the efficacy of oral contraceptives. It is concluded that the overall results have shown oral contraceptives to be an excellent form of contraception with minimal and acceptable side effects and the least metabolic disturbance.

Female hormonal contraceptives, introduced commercially in 1959, contained 10 mg of norethynodrel and .15 mg of mestranol. The estrogen and progesterone doses were progressively reduced over time. In 1989, approximately 60 million couples used oral contraceptives (OCs) ranging from 1% in Japan to 40% in the Netherlands. The monophasic pill contains .01 - .04 mg of ethinyl estradiol (EE), and the biphasic pill contains increasing doses of progesterone and estroprogesterone in the course of the menstrual cycle. Triphasic combined pills contain an initially dominant estrogen dose. In oral sequential pills, estrogen is given on days 14-16 followed by a estroprogesterone for 5-7 days. Micropills with progesterone, injectables with medroxyprogesterone, and 3rd-generation OCs such as gestoden with a low progesterone dose of .04 mg/day and reduced androgenic activity are among other OCs. The OCs are administered in 21-22 day packets. Absolute contraindications include history of venous thrombosis, atherogenic lipid profile, hormone-dependent cancer, and allergy. Relative contraindications include arterial ailments, smoking, hypertension, older age, obesity, and familial history of cardiovascular and cerebrovascular accidents. Interactions with antibiotics (ampicillin and tetracycline) occur as the modified intestinal flora reduces the level of deconjugated EE. Most frequent side effects are depression, modification of libido, ocular disorders, headache, and urinary infection. Benefits include favorable modification of menstrual cycle, and reduction of endometriosis and endometrial and ovarian cancer. Systemic risks such as cardiovascular and blood coagulation effects occur mainly with high-dose OCs. Further topics addressed are the cancer risk and protective effect of OCs, postcoital OCs, traditional contraception, the IUD, RU-486, implants, vaccination with the human antigonadotropine, and the vaginal ring.

The records of 483 patients admitted to the emergency room because of syncope were reviewed. Forty-one patients were found to have drug-related syncope. Thirty-nine experienced syncope related to drugs administered for cardiovascular disease. The most frequently associated diseases were anginal syndrome (22 patients), hypertension (13 patients), and a history of myocardial infarction (6 patients). Thirty-eight patients experienced symptomatic orthostatic hypotension following drug taking (nitrates in 19 patients, beta blockers in 10 patients, nifedipine in 3 patients, prazosin and quinidine in 2 patients each, methyldopa and verapamil in 1 patient each). One patient developed complete heart block as a result of digoxin intoxication. Two patients developed the characteristic picture of anaphylactic reaction (1 with ampicillin, 1 with dipyrone). During one-year follow-up, without the offending medications, no further syncopal episodes were reported by these patients. We conclude that drug-related syncope was more common among our patients with syncope than had been reported previously. It is suggested that drug-related syncope should be taken into consideration in any patient with syncope who is treated by any of the above-mentioned drugs.

A retrospective study was performed in 107 patients with pneumonia in a total of 2231 who were admitted in a Medicine ward, of an University Hospital in Lisbon during 1990. From the studied patients, 50 (46,7%) were females and 57 (53,3%) males. The mean age was 70,7 +/- 15,3 years, with a mean of 12.8 admission days. In the past history it was identified 43 (40%) patients with respiratory illness. In this, the chronic obstructive airways disease were the more prevalent disease in 22 (20.5%) patients. In the other chronic debilitating diseases, registered in 90 (84.1%), we reported in 58 (54.2%) patients among cardiovascular illness, hypertension (H) in 17 (15.8%) cases and H with diabetes mellitus II (DMII) in 14 (13.1%). The most common radiographic pattern was bronchopneumonia in 56 (52.3%) cases and in the respiratory functional study, the partial respiratory insufficiency occurred in 25 (23.4%) cases. In blood test at admission, it was found anaemia in 35 (32.7%) patients, leukocytosis in 72 (67.3%), elevated sedimentation rate in 70 (65.4%), renal dysfunction in 12 (11.2%) and hyperglycemia in 67 (62.6%). Concerning therapeutics, the ampicillin was the most used antimicrobial therapy in 50 (46.7%) cases and the oxygenotherapy was necessary in 45 (42%). Only 29 (27.1%) needed bronchodilators and 3 (2.8%) required mechanical ventilatory support. The evolution was good in 76 (71%) cases and 31 (29%) patients died. The authors conclude that the pneumonia is a frequent disease in the Internal Medicine Clinics, either as admission cause either as complication of other comorbid medical condition and has a high mortality rate. The most important factors for the prognosis were the age of patients and previous diseases. The aim of the authors is to enhance prevention infection in lower respiratory tract, principally in the weak constitutions patients and the prescription of the appropriate therapy according with the judgment presumption and if possible with the isolated microorganism. Identify with the retrospective study, important elements in the clinical process for interpretation of diagnosis and therapeutic attitude and to learn with the preceding experience for future orientation.

Acute renal failure (ARF) is one of the major complications after cardiopulmonary bypass for open heart operations. The present study was undertaken to identify the risk factors for the development of ARF following cardiopulmonary bypass (CPB). Four hundred and forty-seven consecutive patients who underwent open heart procedures from July 1994 to June 1995 were analyzed retrospectively. Their mean age was 55.6 +/- 14.2 (SD) years (range, 18 to 80). Dialysis was instituted whenever a patient exhibited inadequate urine output (<0.5 mL/kg/hr) for 2 to 3 hours despite correction of hemodynamic status and diuretic therapy, especially if fluid overload, hyperkalemia, or metabolic acidosis were also present. Twenty variables were analyzed by univariate analysis; these included nine preoperative variables--age, sex, hypertension, atherosclerosis, diabetes mellitus, left ventricular end-diastolic dimension (LVEDD) >5 cm, preoperative congestive heart failure, renal insufficiency (serum creatinine > or =130 micromol/L on two occasions), and sepsis--10 intraoperative variables--duration of CPB, redo procedures, emergency surgery, use of intraaortic balloon pump (IABP) in operating room, use of gentamicin, use of ceftriaxone, use of sulbactam/ampicillin, requirement of deep hypothermic circulatory arrest, duration of low mean perfusion pressure (mean pressure <50 mmHg for more than 30 minutes), operation on multiple valves--and one postoperative variable--significant hypotension (systolic blood pressure less than 90 mmHg for more than 1 hour). Significant variables or the variables having a trend (p<0.1) to be associated with ARF were included in stepwise multiple logistic regression analyses. Three regression analyses were performed separately. The incidence of ARF requiring dialysis in the study period was 15.0%. Significant risk factors for whole group of patients (regression I) were preoperative renal insufficiency (p<0.0001), postoperative hypotension (p<0.0001), cardiopulmonary bypass time more than 140 min (p<0.005), preoperative congestive heart failure (p<0.01), and history of diabetes mellitus (p<0.01). The risk factors in the valve group of patients (regression II) were preoperative renal insufficiency (p<0.0001) and postoperative hypotension (p<0.05). Risk factors in the CABG patients (regression III) were postoperative hypotension (p=0.0001), CPB time more than 140 min (p<0.05), preoperative renal insufficiency (p<0.05), and age (p<0.05). The authors conclude that preoperative renal insufficiency and postoperative hypotension are the most important independent risk factors for ARF in postcardiac surgical patients. In addition, CPB time greater than 140 minutes and old age are also independent risk factors for ARF in CABG patients. CPB time more than 140 minutes, history of diabetes mellitus, and preoperative congestive heart failure are independent risk factors for development of ARF in our total group of patients. These findings may have important clinical implications in the prevention of ARF in postcardiac surgical patients.

A 70-year-old patient with a history of hypertension and hypercholesterolemia was referred for evaluation of necrotic toes. The patient had a history of several cerebrovascular accidents during the previous month. Initially, she developed sudden-onset left upper extremity weakness which, over the ensuing 4 days, progressed to complete left-sided weakness. This was followed by the development of acute dysarthria. A transesophageal echocardiogram revealed moderate left ventricular hypertrophy, several vegetations on her tri-leaflet aortic valve associated with moderate aortic regurgitation, and a large right atrial thrombus with a mobile component. Bubble studies failed to reveal any septal defects. The patient's electrocardiogram was nonspecific. As serial blood cultures were negative despite fevers of up to 39.8 degrees C, the patient was treated with a 6-week course of intravenous ceftriaxone, ampicillin, gentamicin, and ciprofloxacin for a presumed diagnosis of culture-negative endocarditis. Fungal cultures of the blood were negative. The patient, however, progressed and developed several necrotic toes. Physical examination was significant for ischemic changes of the left first, second, third, and fifth toes, as well as the right first and second toes. Diffuse subungual splinter hemorrhages in the toenails, numerous 2-4-mm palpable purpuric papules on the lower extremities, and nontender hemorrhagic lesions of the soles were also noted. Peripheral and carotid pulses were intact and no carotid bruits were heard. Cardiopulmonary and abdominal examinations were unremarkable. Neurologic examination revealed a disoriented, dysarthric patient with left central facial nerve paralysis, as well as spasticity, hyperactive reflexes, and diminished strength and sensation in the left upper and lower extremities. A left visual field defect and left hemineglect were also present. The patient's last brain computerized tomogram revealed areas of low attenuation consistent with cerebral infarctions in three distinct areas of the brain. These included the left occipitotemporal area, the right parieto-occipital area, and the right posterior frontal region. The regions affected were in the distribution of both the anterior and posterior circulation. No evidence of hemorrhage was noted. The patient subsequently complained of abdominal discomfort. A computerized tomogram of the abdomen with oral and intravenous contrast revealed a 4-cm x 3-cm irregular mass in the tail of the pancreas with several low-attenuation lesions throughout the liver which were consistent with infarctions or metastases. Several splenic infarctions were also present. A biopsy of the tumor revealed pancreatic adenocarcinoma. The patient's carcinoembryonic antigen level was 18. 4 ng/mL (0-3) and the CA 19-9 antigen level was 207,000 U/mL (0-36). The alpha-fetoprotein level was normal. Other significant laboratory findings included a prothrombin time of 16.7 (international normalized ratio, 1.4), an activated partial thromboplastin time of 32 (ratio, 1.3), and a platelet count of 85,000/mm3. The Russell viper venom time, sedimentation rate, and C3 levels were normal, and the patient was negative for antinuclear antibodies, anticardiolipin antibodies, and antibodies to extractable nuclear antigens. Of note, the patient was not receiving any anticoagulation. Blood cultures for mycobacteria and fungi, human immunodeficiency virus serology, and urinalysis and culture were negative. The patient subsequently developed an inferior wall myocardial infarction and was transferred to the coronary care unit. In line with the family's request, aggressive care was ceased and the patient expired. The patient's family refused an autopsy.

A 56-year-old Japanese man with hypertension presented with a 10 days history of high fever, right and left upper quadrant tenderness. An abdominal ultrasonography and computerized tomographic scan revealed a large collection in the right lobe of the liver that was consistent with an abscess. A drainage catheter was placed and purulent fluid was drained. Cultures of the fluid and blood were positive for a strain of ampicillin-resistant Klebsiella pneumoniae. Six days after admission, paraplegia and urinary retention were found. On the neurological examination, deep tendon reflexes of the lower extremities were absent bilaterally. Magnetic resonance imaging scan detected thoracic spinal epidural abscess and paraspinal abscess. He received the emergent decompressive laminectomy. Culture of surgical specimen grew ampicillin-resistant K. pneumoniae. The patient was treated with biapenem intravenously. Thereafter, clinical symptoms improved gradually and he was removed to the professional hospital to continue rehabilitation for gait disturbance on hospital day 147.

The aim of this study was the determinantion of the appearance of urosepsis in patients in the Department of Nephrology Hypertension and internal Diseases, Dialysis Unit, Department of General, Oncologic and Pediatric Urology and Department of Transplantology and Surgery of University Hospital nr 1 of dr. A. Jurasza in Bydgoszcz. In the period of 2006-2008, total 233 isolates were obtained from positive blood culture and 28.8% of these was also related to urinary tract infection. The majority of cases of urosepsis was observed in urologic and transplantologic wards. Among investigated strains, the most frequency isolated species was E. coli. All Enterobacteriaceae strains examined in our study were susceptible to imipenem, the highest rate of resistance was found for ampicillin, six isolates was producing extended-spectrum beta-lactamases and four-AmpC beta-lactamases. Among P. aeruginosa strains there was no resistance to netilmicin and one or two isolates was producing AmpC beta-lactamases or ES L, respectively.

A 66-year-old woman came into the emergency department with a diffuse rash and a cough. She had a rash on the palms of her hands, which had developed the day before, but had improved a bit. She also had a rash on her feet, legs, and lower abdomen, which had developed that morning. She said that over the previous 2 days she had had a fever, dry cough, and some difficulty breathing. Her past medical history was significant for asthma, diabetes, hypertension, and osteoarthritis. Her medications included atenolol, celecoxib, metformin, pioglitazone, and an albuterol inhaler, as needed. In addition, she was on the ninth day of a 10-day course of nitrofurantoin for acute cystitis. She was allergic to ampicillin and erythromycin. On physical exam, she had a fever of 101.5 degrees Fahrenheit. On lung examination, she had diffuse wheezes and mild bibasilar crackles. Examination of her skin revealed a nonpainful, nonpruritic, erythematous, maculopapular rash located on the palms and legs, as well as on her lower abdomen. Chest radiograph showed mild opacification in the bases of the lungs. What is your diagnosis?
