BACKGROUND: Septic abortion is an infection of the uterus and its appendages following any abortion especially, illegally performed induced abortions. It is characterized by a rise of temperature to at least 100.4 degrees F, associated offensive or purulent vaginal discharge and lower abdominal pain and tenderness. AIM: To study maternal mortality and morbidity in induced septic abortions. METHODS: Induced septic abortions were analyzed between April 1992 and September 1999 in TU Teaching hospital. Morbidity indicators were surgery other than curettage, prolonged hospitalization and permanent damage. RESULTS: In 92 cases of induced septic abortions, comprising 6% of total abortions; nine deaths occurred because of disseminated intravascular coagulation, acute renal failure and adult respiratory distress syndrome. Vaginal, intraperitoneal and gum bleeding; epistaxis and malaena resulted in severe anemia (Hb < 6 gm/L) in 11 cases. Wound debridement and skin graft cured two cases of necrotizing fasciitis. One of four conservatively managed tubo-ovarian masses spontaneously drained rectally. In 15 cases laparotomy for pus drainage, salpingectomy, salpingo-oophorectomy, hysterotomy/uterine rent repair was conducted, along with four bowel surgeries and six hysterectomies were performed. Post-operative complications included burst abdomen (one case) and reopened pyoperitoneum, which resulted fecal fistula in three cases, one of these patients died. CONCLUSION: : Induced abortion was proven to be a major detrimental factor for maternal mortality. Morbidity was four times higher than mortality to the extent that patients suffered hemiplegia and forced barrenness.
Bacterial cell walls contain peptidoglycan (PTG), which, among other actions, induces fever. The present experiment evaluated the effects of PTG treatment on early pregnancy and blood plasma concentrations of reproductive hormones. Ewes were injected i.v. with saline or 15, 30 or 60 microg kg(-1) sonicated PTG (Streptococcus pyogenes) on day 5 after mating. Each dose of PTG induced fever. Pregnancy rate at day 25 was not related to incidence of fever but tended to differ among treatments (control, 100%; low, 100%; medium, 67%; high, 60%; P < 0.08). Combined pregnancy rate in ewes from control and low dose groups (100%) was greater than that in ewes from medium and high dose groups (64%, P < 0.01). Ewes with high 13,14-dihydro-15-keto-prostaglandin F(2alpha) (PGFM) concentrations had lower pregnancy rates (6 of 10) than those with low concentrations of PGFM (11 of 11; P < 0.05). Mean cortisol concentrations were higher in treated (2.8 +/- 0.28 microg dl(-1)) than in control (1.1 +/- 0.03 microg dl(-1)) ewes (P < 0.01); the pattern of secretion was biphasic and increased in all treated ewes (P < 0.01). Neither means nor profiles of oestradiol differed with treatment. Mean concentrations and the pattern of concentrations of progesterone were reduced in all treated ewes, as indicated by the time by treatment and linear interaction with treatment (1.2 +/- 0.1 versus 1.6 +/- 0.1 ng ml(-1), P < 0.01). Patterns of LH pulses did not differ from 0 to 4 h or 24 to 28 h after treatment; mean plasma LH concentration was lower in ewes treated with 0, 15 or 30 microg PTG kg(-1) than with 60 microg PTG kg(-1) (P < 0.01). Pregnancy status was not related to plasma concentrations or patterns of LH, oestradiol, progesterone or cortisol. Inflammatory mediators, such as PGF(2alpha), may act directly on the embryo or uterus in ewes treated with PTG.
A full-length cDNA clone of an Encephalomyocarditis virus (EMCV) strain (2887A) isolated from aborted swine fetus was constructed and sequenced. Sequence comparison showed more than 99% nucleotide and amino acid sequence identity with two other EMCV strains, EMCV-PV21 and -R. However, the 2887A genomic sequence showed only about 84% nucleotide identity and 96% amino acid identity with EMCV-B, -D and -PV2 variants. RNA synthesized by in vitro transcription of this cDNA clone was infectious upon transfection of BHK21 cells, as shown by cytopathic effects and identification by neutralization test, and by propagation of the virus released into the culture media. The transcript RNA led to the production of infectious particles despite the presence of two nongenomic nucleotide residues at the 5' end, the short poly(C) tract (C(10)TCTC(3)TC(10)), the short poly(A) tail (7A), and the presence of six nongenomic nucleotides at the 3' end. The rescued virus was also found to be highly pathogenic for mice by intra-peritoneal inoculation producing a fatal disease indistinguishable from that of wild-type virus. An important finding concerning the molecular basis of infectivity was that the in vitro synthesized EMCV RNA transcript is infectious, although it contains a very short poly(A). The availability of the infectious cDNA clone of the reproductive failure strain of EMCV should prove to be useful for studying the molecular basis of the pathogenicity of EMCV in pig.
