Gastric glomus tumour: A case report.

Glomus tumours (GTs) are rare, mesenchymal neoplasms arising from the glomus body. Atypical sites, like the stomach, have been reported with extreme rarity since the usual location lies under the nail beds. We report a rare case of gastric GT in a 28-year-old female presenting with upper abdominal pain, intermittent haematemesis and melena. Contrast-enhanced computed tomography indicated a well-defined, heterogeneously enhancing lesion in the antral region of the stomach and a possibility of gastrointestinal (GI) stromal tumour (GIST). Upper GI endoscopy showed a wide-based lesion in the sub-mucosal plane with ulcerated mucosa. Laparoscopic excision of the tumour with primary closure of the defect was performed, with an uneventful post-operative course. Histopathological and immunohistochemical findings confirmed a gastric GT. Follow-up clinical and endoscopic examinations were normal. Gastric GTs should be a rare differential in patients with suspected GIST and upper GI bleed.

Strategic approach of multifaceted antibacterial mechanism of limonene traced in Escherichia coli.

Antibacterial potential of Limonene against Multi Drug Resistant (MDR) pathogens was studied and mechanism explored. Microscopic techniques viz. Fluorescent Microscopy (FM), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM) indicated membrane disruption, cellular leakage and cell death of Escherichia coli (E. coli) cells when treated with limonene. Leakage of intracellular proteins, lipids and nucleic acid confirmed membrane damage and disruption of cell permeability barrier. Further, release of intracellular ATP, also suggested disruption of membrane barrier. Interaction of limonene with DNA revealed its capability in unwinding of plasmid, which could eventually inhibit DNA transcription and translation. Differential expression of various proteins and enzymes involved in transport, respiration, metabolism, chemotaxis, protein synthesis confirmed the mechanistic role of limonene on their functions. Limonene thus can be a potential candidate in drug development.

Fetal Autopsy-Categories and Causes of Death at a Tertiary Care Center.

BACKGROUND: A fetus is defined from 8 weeks after conception until term while in the uterus. Fetal death is defined as death of the fetus before the complete expulsion or extraction from the mother, irrespective of the duration of pregnancy that is not an induced termination of pregnancy. The causes of fetal death determined after fetal autopsy can be categorized according to the classification proposed by Cunningham and Hollier as fetal, placental, and maternal. METHODS: All fetuses dying in utero, that is, prior to birth, regardless of the gestational age, to the mothers admitted in the Department of Obstetrics and Gynecology along with the respective placentas were received in the Department of Pathology, MGM Medical College, Aurangabad, after an informed and written consent from October 26, 2017, to October 30, 2019, and were included in this study. Clinical details along with obstetric history and antenatal ultrasonographic findings were also recorded. Anthropometric examination of the fetus was performed and evisceration was then done using the Rokitansky technique. Representative sections from each of the organs were taken and kept in tissue cassettes and processed for routine hematoxylin and eosin staining. RESULTS: This study was done on 33 cases of fetal death. Most fetal deaths occurred in the gestational age between 15 and 19 weeks (14 cases [42.42%]) and the least amount during 35 to 39 weeks (2 cases [6.06%]). The cause of death could not be ascertained in 6 cases (18.18%), whereas the maximum cases had fetal factor as the cause of death (15 cases [45.45%]). Maternal causes were seen in only 4 cases (12.12%). Gestational hypertension was seen to be the most common maternal factor associated with fetal death, which comprised 24.24% of cases (8 of 33). Thirteen of the total 33 cases did not have any associated obstetric complication. Of the total 33 fetal deaths, only 7 had associated placental defects on gross examination. Twenty-six placentas did not show any gross abnormality. Of these 7 cases, 5 were seen to have placental infarction. CONCLUSIONS: Fetal autopsy is a valuable and cost-effective modality for the confirmation of cause of fetal death. Fetal autopsy can also prove beneficial to the parents in planning for future pregnancies. Fetal autopsy can serve as the ultimate tool in diagnosing cause of fetal death in cases where no other diagnostic clue is available. Therefore, it should be encouraged and couples to be counseled regarding its importance and clinical utility.
