Abdominal swelling and obstructive uropathy due to hematometrocolpos secondary to imperforate hymen: a case report.

Imperforate hymen is an uncommon congenital anomaly of the female genital tract and can lead to the collection of blood in the vagina and the uterus. Most patients are not diagnosed until menarche when they present with symptoms such as cyclic abdominal and pelvic pain, constipation, tenesmus, back pain, and difficulties with urination in association with lack of menses. We discuss the case of an adolescent female who presented with the complaint of an increasing abdominal swelling along with the urgency and a sense of incomplete urination. She had not attained menarche. A diagnosis of hematometrocolpos was made based on computed tomography findings. Subsequent perineal examination revealed a bulging imperforate hymen. Hymenotomy was performed with complete resolution of the symptoms. This case highlights the importance of keeping a high index of suspicion for this condition in patients presenting with these symptoms and the importance of appropriate gynecologic examination.

Antimicrobial activity, structural evaluation and vibrational (FT-IR and FT-Raman) study of pyrrole containing vinyl derivatives.

In this paper we present structural and vibrational study of three vinylpyrrole derivatives: 2-Cyano-3-(1H-pyrrol-2-yl)-acrylamide (CPA), 1-(1H-Pyrrol-2-yl)-Pent-1-en-3-one (PP) and 1-(1H-Pyrrol-2-yl)-but-1-en-3-one (PB), using ab initio, DFT and experimental approaches. The quantum chemical calculation have been performed on B3LYP method and 6-311+G(d,p) basis set. The experimental FT-IR and Raman wavenumbers were compared with the respective theoretical values obtained from DFT calculations and found to agree well. The experimental FT-IR and Raman study clearly indicate that the compound exist as dimer in solid state. The binding energies of (CPA), (PP) and (PB) dimers are found to be 20.95, 18.75 and 19.18 kcal/mol, respectively. The vibrational analysis shows red shifts in v(N-H) and v(C=O) stretching as result of dimer formation. Stability of the molecule arising from hyperconjugative interactions and charge delocalization has been analyzed using NBO analysis. Topological and energetic parameters reveal the nature of interactions in dimer. The local electronic descriptors analyses were used to predict the reactive sites in the molecule. Calculated first static hyperpolarizability of CPA, PP and PB is found to be 10.41×10(-30), 18.93×10(-30), 18.29×10(-30) esu, respectively, shows that investigated molecules will have non-linear optical response and might be used as non-linear optical (NLO) material. These vinylpyrrole compounds (CPA), (PP) and (PB) showed antifungal and antibacterial activity against Aspergillus niger and gram-positive bacteria Bacillus subtili.
