Early Engineering

In the late 1950s and early-to-mid-1960s, Glasgow led the world in the development of diagnostic obstetric ultrasound technology, the result of fortuitous collaboration between key individuals advancing the application of an industrial technology. Originally used to detect flaws in metal pressure vessels, the obstetrician Ian Donald, during his military service, reflected on how ultrasound could benefit his own field. Donald involved the engineer Tom Brown to tackle the technical challenges. Brown, in turn, employed a young graduating industrial designer, Dugald Cameron, to address the design, aesthetic and ergonomic aspects of these early engineering prototypes. While previous accounts of these developments have rightly celebrated the medical, technical engineering and imaging achievements of this innovative technology, the discussion of the role of the creative design expertise which addressed serious ergonomic, aesthetic and production manufacturing shortcomings of the first prototypes has been less coherent. This article relates, through key drawings, extracts from witness statements and discussions with Cameron himself, the key design decisions and features resulting in the Sundén and Diasonograph machines, the latter being the world’s first commercial production-series obstetric ultrasound machine, deployed in Glasgow hospitals and beyond.

Clinical and anamnesis analysis as well as analysis of the course and outcome of the present pregnancy was performed on 595 patients with complicated obstetrical and gynecological history (COGH) habitual pregnancy loss, infertility, genital chronic processes. Control groupconsisted of 5O healthy women. Immunofluorescent analysis was used to reved antiphospholipid antibodies on blood plasma. Antiphospholipid antibodies were found in 42% of COGH women. No antiphospholipid antibodies were seen in the control group. In all patients of the studied groupthe course of pregnancy was accompanied with signs of threatened abortion, gestosis. 29% (p O, O1) patients had preterm labor and spontaneous abortion occurred in 18% (p O, O1) of cases. Perinatal mortality was 9, 8%4, 16.

Abortion Case

Chlamydia pecorum is a common gastrointestinal inhabitant of livestock but infections can manifest in a broad array of clinical presentations and in a range of host species. While C. pecorum is a known cause of ovine abortion, clinical cases have only recently been described in detail. Here, the prevalence and sequence types (STs) of C. pecorum in ewes from a property experiencing high levels of perinatal mortality (PNM) in New South Wales (NSW), Australia, were investigated using serological and molecular methods. Ewes that were PNM+ were statistically more likely to test seropositive compared to PNM− ewes and displayed higher antibody titres; however, an increase in chlamydial shedding from either the rectum, vagina or conjunctiva of PNM+ ewes was not observed. Multilocus sequence typing (MLST) indicated that C. pecorum ST23 was the major ST shed by ewes in the flock, was the only ST identified from the vaginal site, and was the same ST detected within aborted foetal tissues. Whole genome sequencing of C. pecorum isolated from one abortion case revealed that the C. pecorum plasmid (pCpec) contained a unique deletion in coding sequence 1 (CDS1) that was also present in C. pecorum ST23 shed from the ewes. A further unique deletion was noted in a polymorphic membrane protein gene (pmpG) of the C. pecorum chromosome, which warrants further investigation given the role of PmpG in host cell adherence and tissue tropism.This study describes novel infection parameters in a sheep flock experiencing C. pecorum-associated perinatal mortality, provides the first genomic data from an abortigenic C. pecorum strain, and raises questions about possible links between unique genetic features of this strain and C. pecorum abortion.
