Most approaches use interactive priors to find tumours and then segment them based on tumour-centric candidates. A fully convolutional network is demonstrated for end-to-end breast tumour segmentation. When confronted with such a variety of options, to enhance tumour detection in digital mammograms, one uses multiscale picture information.

Seventy-eight infectious episodes in 75 cancer patients with adequate granulocyte counts were treated with cefotaxime. Sixty-six episodes were evaluable. The overall cure rate was 77% (51/66).

Piperacillin and vancomycin were used as initial empirical therapy for 211 febrile episodes in cancer patients. The response rate in 95 episodes of documented infection was 72%. The response of bacteremias, soft tissue infections, and pneumonias was 78, 71, and 38%, respectively.

Bacteremia caused by newly described Campylobacter-like organisms occurred in two immunosuppressed homosexual patients with tuberculosis. Although these organisms grow well in aerobic bottles using a radiometric blood culture system, they are not readily seen in gram-stained smears and are easily missed if routine subculture methods are used. Microscopic examination of wet preparations and subculture to brucella agar base supplemented with 10% sheep blood and incubated in microaerophilic conditions are useful for identification and isolation.

The majority had leukemia and neutropenia. The rate of cures during the 231 confirmed infections was 65% for moxalactam and ticarcillin and 64% for moxalactam and tobramycin.

Thirty-eight isolates of gram-negative bacilli resistant to four new beta-lactam antibiotics, aztreonam, moxalactam, ceftazidime, and cefoperazone, were tested in the presence of two beta-lactam inhibitors, clavulanic acid and sulbactam. Microorganisms tested included 22 isolates of Pseudomonas species, 5 of Klebsiella species, and 11 of Enterobacter species. A 2- to 10-fold decrease in minimum inhibitory concentration was noted when antibiotics and beta-lactamase inhibitors were combined compared to antibiotics alone.

Computerized tomography of the brain documented a left parieto-occipital abscess. A specimen obtained at the time of surgical excision of the lesion revealed organisms with morphologic features of Toxoplasma gondii and Candida.

Of the 43 cases of human cryptosporidiosis reported, 27 patients in whom either humoral or cell-mediated immune defects were present had chronic protracted diarrhea that was almost invariably unresponsive to therapy and culminated in death. In contrast, 16 patients with intact immune systems had either self-limited disease or were asymptomatic.

This case underlines the value of a thorough gastrointestinal evaluation of all patients with S bovis infection, and the need for a neurologic investigation even with minor neurologic manifestations.

The records of 714 neutropenic cancer patients who were treated with high doses of a combination of beta-lactam antibiotics were analyzed. In 268 patients, coagulation parameters were measured at least once before, during, and after therapy. Alterations on the prothrombin time, activated partial thromboplastin time, and thrombin time were found in those regimens containing a semisynthetic penicillin, cefamandole, and moxalactam.

While she was already receiving amphotericin for suspected Aspergillus infection, she developed hepatomegaly and abnormal liver enzymes with high serum bilirubin. The blood cultures were negative.

Patients were grouped according to their neutrophil count into neutropenic and non-neutropenic (less than 1000 and greater than 1000/mm3) respectively. Two hundred and seventy-five episodes were evaluated.

Using a recently developed radioimmunoassay, we performed 15 vancomycin pharmacology studies in cancer patients with infections. Vancomycin (500 mg) was infused intravenously for 30 min every 6 h for up to 7 days. The plasma disappearance curve was biphasic, with an initial half-life of less than 30 min.

A dose of 12 g/day was administered according to two different schedules, one for neutropenic patients (neutrophil count, less than 1,000/mm3), the other for nonneutropenic patients. The rate of response for 85 episodes of documented infection was 68%.
