A Prospective Multi-centric Study of Acceptance, Insertion and Follow-Up of Postpartum Insertions of IUCD.

Purpose of the Study: The unmet need for contraception in the postpartum period is a major challenge in our country. Unintended pregnancies are highest in the first year after birth, and postpartum IUCD insertion is an effective way to counter this problem. This study was planned to build up data for acceptance and follow-up of postpartum IUCD insertions. Methods: The present study has included data of PPIUCD insertions and follow-up from seven institutions over a period of 6 months. The case recruitment lasted for 3 months, including only those who had PPIUCD insertions in this period, and they were followed up for a period of 6 months. The follow-up of patients was at 6 weeks and 6 months. All issues were addressed including side effects, expulsions, myths surrounding the device, etc., along with routine postnatal care. Results and Conclusion: There were 5227 deliveries and 1895 insertions. The acceptance rate was 36%, and a follow-up at 6 weeks and 6 months showed up an expulsion rate of approximately 4% and a removal rate of 5%. Overall, at the end of 6 months we have a continuation rate of 90%. This shows that a dedicated approach to postpartum contraception will definitely bring down incidence of unintended pregnancies.

Spontaneous pneumopericardium an unusual complication in a patient of HIV and pulmonary tuberculosis.

Pneumopericardium is defined as a collection of air or gas in the pericardial cavity. It is a rare entity and spontaneous pneumopericardium is even rarer. It is a rare complication of tuberculosis and human immunodeficiency virus and just three cases have been reported so far.

Eosinophilic pleural effusion and giardiasis: A causal or a casual relationship?

A case of bilateral eosinophilic pleural effusion with coincidental intestinal infestation of giardia lamblia is being reported. After reviewing the possible causes of this type of pleural effusion, no clinical or laboratory data were obtained which could explain this condition except giardiasis. Moreover the clearance of pleural effusion with the treatment of giardia with metronidazole suggests giardia as the probable cause of bilateral eosinophilic pleural effusion.

Real-time monitoring of ligand-receptor interactions with fluorescence resonance energy transfer.

FRET is a process whereby energy is non-radiatively transferred from an excited donor molecule to a ground-state acceptor molecule through long-range dipole-dipole interactions. In the present sensing assay, we utilize an interesting property of PDA: blue-shift in the UV-Vis electronic absorption spectrum of PDA (Figure 1) after an analyte interacts with receptors attached to PDA. This shift in the PDA absorption spectrum provides changes in the spectral overlap (J) between PDA (acceptor) and rhodamine (donor) that leads to changes in the FRET efficiency. Thus, the interactions between analyte (ligand) and receptors are detected through FRET between donor fluorophores and PDA. In particular, we show the sensing of a model protein molecule streptavidin. We also demonstrate the covalent-binding of bovine serum albumin (BSA) to the liposome surface with FRET mechanism. These interactions between the bilayer liposomes and protein molecules can be sensed in real-time. The proposed method is a general method for sensing small chemical and large biochemical molecules. Since fluorescence is intrinsically more sensitive than colorimetry, the detection limit of the assay can be in sub-nanomolar range or lower. Further, PDA can act as a universal acceptor in FRET, which means that multiple sensors can be developed with PDA (acceptor) functionalized with donors and different receptors attached on the surface of PDA liposomes.
