Atypical presentations of ectopic pregnancies in a rural tertiary care hospital-A case series.

In spite of advances in medical sciences, diagnosis of ectopic pregnancy eludes the clinician. In this case series, we describe three variants of life-threatening pregnancies. The successful management of these cases hinged on a strong index of suspicion and early detection. Heterotopic pregnancy is the occurrence of two pregnancies in different implantation sites at the same time, which is uncommon. Heterotopic pregnancy is uncommon in natural conception, despite its prevalence in assisted reproductive technologies. A strong index of suspicion and timely laparotomy was life-saving for the woman. Caesarean scar pregnancy is a form of ectopic pregnancy in which an aberrant pregnancy is implanted at the hysterotomy site of a prior caesarean procedure. Unexplained excessive bleeding at the time of medical termination of pregnancy prompted us to explore and make a timely diagnosis of caesarean scar pregnancy. Finally, tubal choriocarcinoma is a very aggressive, extremely rare trophoblastic tumour that can be either gestational or non-gestational. High serum beta HCG raised the suspicion and timely laparotomy confirmed the diagnosis. An alert clinician who takes timely decisions can avert life-threatening complications in these pregnancies.

Serum migration inhibitory factor levels in periodontal health and disease, its correlation with clinical parameters.

OBJECTIVES: Periodontal infections are an important risk factor for systemic disease and are driven primarily by the cytokines. Migration Inhibitory Factor (MIF) is a key cytokine which mediates acute and chronic inflammation alongside, a molecular link between chronic inflammation and immune mediated conditions. Hence, the present study was carried to measure the serum MIF levels in periodontal health, disease and to correlate the levels with the clinical parameters. MATERIAL AND METHODS: Sixty subjects were divided into three groups (each group n = 20) based on the gingival index (GI), probing pocket depth (PPD), and clinical attachment level (CAL) as group I healthy; group II gingivitis; and group III chronic periodontitis. The serum MIF level was measured using quantitative sandwich enzyme immunoassay technique. RESULTS: Highest level was detected in Group III with a mean of 71.8 ng/ml and the lowest in group I (6.1 ng/ml). Serum MIF levels did not correlate with the clinical parameters. CONCLUSION: Increased serum MIF levels in chronic periodontitis patients suggest its role as an inflammatory biomarker and may have a role in inflating the systemic inflammation. Summary: Serum Migration inhibitory factor can be used as an inflammatory marker for periodontal disease.

Interactive effects of silicon and arbuscular mycorrhiza in modulating ascorbate-glutathione cycle and antioxidant scavenging capacity in differentially salt-tolerant Cicer arietinum L. genotypes subjected to long-term salinity.

Salinity is the major environmental constraint that affects legume productivity by inducing oxidative stress. Individually, both silicon (Si) nutrition and mycorrhization have been reported to alleviate salt stress. However, the mechanisms adopted by both in mediating stress responses are poorly understood. Thus, pot trials were undertaken to evaluate comparative as well as interactive effects of Si and/or arbuscular mycorrhiza (AM) in alleviating NaCl toxicity in modulating oxidative stress and antioxidant defence mechanisms in two Cicer arietinum L. (chickpea) genotypes-HC 3 (salt-tolerant) and CSG 9505 (salt-sensitive). Plants subjected to different NaCl concentrations (0-100 mM) recorded a substantial increase in the rate of superoxide radical (O2 (·-)), H2O2, lipoxygenase (LOX) activity and malondialdehyde (MDA) content, which induced leakage of ions and disturbed Ca(2+)/Na(+) ratio in roots and leaves. Individually, Si and AM reduced oxidative burst by strengthening antioxidant enzymatic activities (superoxide dismutase (SOD), catalase (CAT) and guaiacol peroxidase (GPOX)). Si was relatively more efficient in reducing accumulation of stress metabolites, while mycorrhization significantly up-regulated antioxidant machinery and modulated ascorbate-glutathione (ASA-GSH) cycle. Combined applications of Si and AM complemented each other in reducing reactive oxygen species (ROS) build-up by further enhancing the antioxidant defence responses. Magnitude of ROS-mediated oxidative burden was lower in HC 3 which correlated strongly with more effective AM symbiosis, better capacity to accumulate Si and stronger defence response when compared with CSG 9505. Study indicated that Si and/or AM fungal amendments upgraded salt tolerance through a dynamic shift from oxidative destruction towards favourable antioxidant defence system in stressed chickpea plants.

Influence of cadmium stress and arbuscular mycorrhizal fungi on nodule senescence in Cajanus cajan (L.) Millsp.

Cadmium (Cd) causes oxidative damage and affects nodulation and nitrogen fixation process of legumes. Arbuscular mycorrhizal (AM) fungi have been demonstrated to alleviate heavy metal stress of plants. The present study was conducted to assess role of AM in alleviating negative effects of Cd on nodule senescence in Cajanus cajan genotypes differing in their metal tolerance. Fifteen day-old plants were subjected to Cd treatments--25 mg and 50 mg Cd per kg dry soil and were grown with and without Glomus mosseae. Cd treatments led to a decline in mycorrhizal infection (MI), nodule number and dry weights which was accompanied by reductions in leghemoglobin content, nitrogenase activity, organic acid contents. Cd supply caused a marked decrease in nitrogen (N), phosphorus (P), and iron (Fe) contents. Conversely, Cd increased membrane permeability, thiobarbituric acid reactive substances (TBARS), hydrogen peroxide (H2O2), and Cd contents in nodules. AM inoculations were beneficial in reducing the above mentioned harmful effects of Cd and significantly improved nodule functioning. Activities of superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) increased markedly in nodules of mycorrhizal-stressed plants. The negative effects of Cd were genotype and concentration dependent.
