Synchronous dual malignancy: a rare case report of carcinoma breast with carcinoma gall bladder

Incidence of multiple primary cancers is reported to be between 0.18% to 17.2% in various studies. Occurrence of breast and gall bladder malignancy as synchronous malignancy is very rare. We are reporting one of such rare case. Our patient, a 64 years old lady had a unique presentation. She underwent laparoscopic cholecystectomy for a clinical diagnosis of cholelithiasis. Histopathology turned out to be adenocarcinoma of the gall bladder (Stage II A). A clinical examination done at the time of presentation to our institute revealed suspicious thickening of the skin of the left breast and a subsequent tru-cut biopsy revealed infiltrating ductal carcinoma. Hormone receptor immunohistochemistry revealed oestrogen receptor (ER) negative progesterone receptor (PR) negative and Her2neu negative tumour. Further evaluation revealed a widespread metastatic disease. She was treated with palliative radiotherapy, chemotherapy and zolendronate. She had an aggressive clinical course and succumbed to her illness within four months after diagnosis of dual malignancy. There is a high incidence of gall bladder carcinoma along the Gangetic belt of Northern India. Presence of dual malignancy with gall bladder carcinoma as one primary in these geographic location needs to be further explored for sporadic environmental factors or other genetic alterations as possible causative factors

Selective Colorimetric Detection of Nitrite in Water using Chitosan Stabilized Gold Nanoparticles Decorated Reduced Graphene oxide

© 2017 The Author(s). Excess nitrite (NO 2 - ) concentrations in water supplies is considered detrimental to the environment and human health, and is associated with incidence of stomach cancer. In this work, the authors describe a nitrite detection system based on the synthesis of gold nanoparticles (AuNPs) on reduced graphene oxide (rGO) using an aqueous solution of chitosan and succinic acid. The AuNPs-rGO nanocomposite was confirmed by different physicochemical characterization methods including transmission electron microscopy, elemental analysis, X-ray diffraction, UV-visible (UV-vis) and Fourier transform infrared spectroscopy. The AuNPs-rGO nanocomposite was applicable to the sensitive and selective detection of NO 2 - with increasing concentrations quantifiable by UV-vis spectroscopy and obvious to the naked eye. The color of the AuNPs-rGO nanocomposite changes from wine red to purple with the addition of different concertation of NO 2 - . Therefore, nitrite ion concentrations can be quantitatively detected using AuNPs-rGO sensor with UV-vis spectroscopy and estimated with the naked eye. The sensor is able to detect NO 2 - in a linear response ranging from 1 to 20 μM with a detection limit of 0.1 μM by spectrophotometric method. The as-prepared AuNPs-rGO nanocomposite shows appropriate selectivity towards NO 2 - in the presence of potentially interfering metal anions

Case Report - Carcinoma of uterine cervix with isolated metastasis to fibula and its unusual behavior: Report of a case and review of literature

Bone metastasis from carcinoma cervix is uncommon, especially in the distal appendicular skeleton. A 36 year old lady presented with carcinoma of uterine cervix, FIGO, stage IIb. She was treated with radical radiotherapy. Nine months later, she developed an isolated lytic lesion in right fibula, which turned out to be a metastatic lesion. The patient is doing well, 3 years after the surgical excision of metastasis. This is one of the few documented cases of metastasis to fibula, arising from carcinoma of uterine cervix and probably the first with isolated metastasis of this site. Unlike the dismal outcome commonly seen in patients with bone secondaries, she continues to be disease free and alive at 39 months of follow up, after the development of skeletal metastasis

Supine headache and papilledema: A case and review of cerebral venous sinus thrombosis

Key clinical message Cerebral venous sinus thrombosis (CVST) should be on the differential for intracranial hypertension, and the preferred diagnostic tests are CT venogram or MR venography. Abstract Cerebral venous sinus thrombosis (CVST) is a rare cause of stroke and is on the differential for intracranial hypertension. Non‐contrast head CT is often normal. CT venogram or MR venography are the preferred diagnostic tests, as was required in our patient. We review the presentation, diagnosis, and management of CVST
