To understand the importance of frequent deletion of chromosomal 11q23.3-24.3 region in cervical carcinogenesis, alterations (deletion/ methylation/mutation/expression) of the candidate genes LOH11CR2A, EI24 and CHEK1 located in the region were analyzed in 29 cervical intraepithelial neoplasia (CIN), 112 cervical carcinoma (CACX) samples and two CACX cell lines. The deletion frequency of these genes was low in CIN than in CACX [CIN: CHEK1: 28%, EI24: 21%, LOH11CR2A: 15% and CACX: CHEK1: 51%, EI24: 41%, LOH11CR2A: 36%]. Similar trend was seen in promoter methylation of these genes [CIN: CHEK1: 10%, EI24: 3%, LOH11CR2A: 3% and CACX: CHEK1: 55%, EI24: 31%, LOH11CR2A: 14%]. Mutations of the genes are a rare event. Overall alterations (deletion and methylation) of CHEK1 and EI24 were associated with progression of CACX. Quantitative mRNA expression analysis showed reduced expression of the three genes in concordance to their molecular alterations. A shorter isoform of CHEK1 lacking exon 8, hence impaired in substrate binding capacity, was found in two samples. Immunohistochemical analysis showed nuclear expression of Chek1, p-Chek1 and Ei24 in tumor tissues, whereas the cell lines exhibited both nuclear and cytoplasmic expression of Chek1 and Ei24, as is also evident from Western blot analysis suggesting differential localization of the proteins. Alterations of CHEK1 and EI24 coupled with tumor stage and early sexual debut (≤19 years) predicted worst prognosis. Thus, our data suggest that inactivation of EI24 and CHEK1 through two independent mechanisms contributes to the development of CACX. © Copyright 2010 UICC.

Objectives To study maternal heart disease in an Indian setting for: (1) different etiological factors, (2) different types of lesions, and (3) maternal and perinatal outcome. Methods 281 women with heart disease who delivered ≥28 weeks of gestation at different teaching institutions (tertiary care centres) in India were studied. Results Rheumatic heart disease (n = 195; 69.4 %) with isolated mitral stenosis (n = 75; 26.7 %) were the commonest. Septal defect (n = 27; 9.6 %) was the predominant lesion among the congenital heart disease (n = 60; 21.3 %) patients, whereas in the miscellaneous group (n = 26; 9.2 %), ischemic heart disease (n = 10; 3.6 %) was the leading cause. Multiple cardiac lesions were also diagnosed in 100 (35.58 %) women. In 87 (31 %) women, diagnosis was made first time in labor. Majority n = 131, (46.6 %) had spontaneous vaginal delivery and few (n = 9; 3.3 %) required induction of labor. Cardiac complications were noted in 72 women (25.6 %). There were three (1.06 %) maternal deaths and perinatal mortality was 4 % (n = 11). Conclusion In this study, rheumatic heart disease in pregnancy is still predominant though acquired cardiac lesions are rising. In rheumatic heart disease, mitral valve involvement was the commonest and multiple valve lesions were a major observation. Most common obstetric complication was small for gestation baby. Maternal morbidities in the unbooked women are high and congestive cardiac failure was the major cardiac complication. © Federation of Obstetric & Gynecological Societies of India 2012.

Labetalol, a combined alfa and beta-adrenergic receptor antagonist, is used as an antihypertensive drug. We report a case of an acute rise in blood pressure and lower limb pain due to the inadvertent intrathecal administration of labetalol, mistaking it for bupivacaine, during obstetric anesthesia. The situation was rescued by converting to general anesthesia. The cesarean delivery was uneventful, and mother as well as newborn child showed no ill-effect. This particular medication error was attributable to a failure on the part of the doctors administering the injection to read and cross-check medication labels and the practice of keeping multiple injections together. In the absence of an organized medication error reporting system and action on that basis, such events may recur in future. © 2015 Indian Journal of Pharmacology Published by Wolters Kluwer - Medknow.

Hydatid disease is a significant health problem in endemic areas. While occurrence of the cysts in the liver and lung is common, mediastinal localisation is extremely rare. We report the case of a 35-year-old male who presented with a painless swelling on the right side of the neck and features of superior vena caval obstruction. Chest radiography and computed tomography (CT) suggested a cyst in the right upper lobe, extending into the right supraclavicular region as well as another cyst in the left lung. Thoracotomy revealed that the right-sided cyst was actually mediastinal in location and had herniated through the thoracic inlet compressing the superior vena cava (SVC). Both cysts were removed in two separate operations and symptoms of SVC compression subsided after removal of the right-sided cyst. Histopathology was consistent with a hydatid disease.

We report a case of a patient suffering from multidrug-resistant pulmonary tuberculosis (MDR-PTB) who later developed an invasive infection of the respiratory tract with a rapidly growing non-tuberculous mycobacteria (NTM), recently identified as Mycobacterium massiliense, closely related to M. abscessus. To the best of our knowledge, this is the first case of M. massiliense infection being reported from India.
