Soil samples with and without a past history of dimethyl-2,3,5,6-tetrachloroterephthalate (DCPA) treatment were obtained from New York. A third sample was obtained from a field in Colorado where DCPA had been ineffective as a herbicide. The populations of bacteria and actinomycetes in these soils were determined and the actinomycetes were more prevalent in the samples with previous DCPA treatment than in untreated samples. Subsequent treatment resulted in an increase in actinomycete population and little change in bacterial population. In pure culture and in soils, the addition of DCPA had no adverse effect upon microbial growth, and several microorganisms appeared to utilize the herbicide as a carbon source. Two degradation products were methyl-2,3,5,6-tetrachloroterephthalate and 2,3,5,6-tetrachloroterethalic acid.

A Family and Maternity Care Program (FMCP) for pregnant addicts, their spouses and the newborn infants was organized at the State University of New York Downstate Medical Center. Twenty-five percent of the women were treated for syphilis; 18% had a recurrent or recent past history of hepatitis. Obstetrical complications were reduced or eliminated by careful obstetrical surveillance. None of the mothers signed out against medical advice postpartum. Of the 51 living infants delivered within the study period, there were 17 infants weighing less than 2,500 gm. The Apgar score at one minute was 7 or higher in 84% of the infants. An excessive incidence of congenital malformation was not seen. Ninety-four percent of the infants developed withdrawal symptoms, 6% of whom convulsed repetitively. Infant withdrawal, however, was unassociated with an increase in mortality or known prolonged morbidity. This low-dose methadone program coupled with intense psychosocial support appeared to alleviate many of the common problems associated with addiction in pregnancy, but failed to prevent withdrawal in the newborn.

An 82-year-old woman was referred to the orthopedic department with a three-month history of low-grade fever. She had a known past history of type 2 diabetes. She had been unwell for last 5-days, complaining of feeling hot and 'shivery' with general aches, particularly in her right shoulder. The staff in the residential home where she lived had called the general practitioner who had prescribed a three-day course of trimethoprim for a suspected urinary tract infection. On examination, she was pyrexia with a temperature of 39.5°C. She was drowsy but reusable. Pulse was 125 beats per minute and regular. Blood pressure was 90/55 mmHg. Heart sounds were normal with no added sounds or murmurs. The chest was clear. Her abdomen was soft and non-tender with no palpable masses or organs. The skin overlying the right shoulder was warm to touch and erythematous. She was unable to tolerate any passive movement of the joint. A plain x ray of her shoulder shows lucent defects in the head of the humerus with loss of the normally well-corticated surface. This is consistent with osteomyelitis. Two of 2-blood cultures and numerous operative cultures grew MRSA. His subsequent treatment consisted of intravenous vancomycin, achieving plasma drug levels approximating 24 μg/mL. This treatment was extended for 8 weeks, given the clinical concern for possible osteomyelitis in an area. Treatment was complicated by significant a decline in hearing. Biodegradable drug delivery systems provide a method for local delivery of drugs in deeper tissues, obviating parenteral or enteral usage; in some situations, a significant advantage is that much higher doses and/or strengths of the drug can be delivered locally than can be tolerated if the drug is delivered systemically. In this case report, we discussed the use of Biodegradable Antibiotic Delivery Systems in treatment chronic osteomyelitis.

This roundtable grew out of conversations between filmmaker Rea Tajiri, programmer Abby Sun, and scholar Vince Schleitwiler about a misunderstood chapter in the history of Asian American film and media: New York City in the eighties, a vibrant capital of Asian American filmmaking with a distinctively experimental edge. To tell this story, Rea Tajiri contacted her artist contemporaries Shu Lea Cheang and Roddy Bogawa as well as writer and critic Daryl Chin. Daryl had been a fixture in New York City art circles since the sixties, his presence central to Asian American film from the beginning. The scope of this discussion extends loosely from the mid-seventies through the late nineties, with Tajiri, Abby Sun, and Vince Schleitwiler initiating topics, compiling responses, and finalizing its form as a collage-style conversation.

H. Lawrence Freeman's “Negro Jazz Grand Opera,” Voodoo, was premiered in 1928 in Manhattan's Broadway district. Its reception bespoke competing, racially charged values that underpinned the idea of the “modern” in the 1920s. The white press critiqued the opera for its allegedly anxiety-ridden indebtedness to nineteenth-century European conventions, while the black press hailed it as the pathbreaking work of a “pioneer composer.” Taking the reception history of Voodoo as a starting point, this article shows how Freeman's lifelong project, the creation of what he would call “Negro Grand Opera,” mediated between disparate and sometimes apparently irreconcilable figurations of the modern that spanned the late nineteenth century through the interwar years: Wagnerism, uplift ideology, primitivism, and popular music (including, but not limited to, jazz). I focus on Freeman's inheritance of a worldview that could be called progressivist, evolutionist, or, to borrow a term from Wilson Moses, civilizationist. I then trace the complex relationship between this mode of imagining modernity and subsequent versions of modernism that Freeman engaged with during the first decades of the twentieth century. Through readings of Freeman's aesthetic manifestos and his stylistically syncretic musical corpus I show how ideas about race inflected the process by which the qualitatively modern slips out of joint with temporal modernity. The most substantial musical analysis examines leitmotivic transformations that play out across Freeman's jazz opera American Romance (1924–29): lions become subways; Mississippi becomes New York; and jazz, like modernity itself, keeps metamorphosing. A concluding section considers a broader set of questions concerning the historiography of modernism and modernity.
