TL;DR: Various treatment options in patients with LABC are reviewed which should possibly help in guiding the clinicians for optimal management of LABC.
Abstract: Locally advanced breast cancer (LABC) accounts for a sizeable number (30-60%) of breast cancer cases and is a common clinical scenario in developing countries. The treatment of LABC has evolved from single modality treatment, consisting of radical mutilating surgery or higher doses of radiotherapy in inoperable disease to multimodality management, which along with the above two included systemic therapy. Neoadjuvant chemotherapy (NACT) has made a tremendous impact on the management of LABC. NACT was initiated to institute systemic therapy upfront at the earliest in this group of patients with a high risk of micrometastasis burden. While NACT did not yield a survival advantage, it has however made breast conservation possible in selected group of cases. Large number of studies and many randomised trials have been done in women with LABC in order to improve the therapeutic decisions and also the local control and survival. With this background we have reviewed various treatment options in patients with LABC which should possibly help in guiding the clinicians for optimal management of LABC.

TL;DR: Fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET) is a functional imaging modality that can be used to study the effects and efficacy of RFA.
Abstract: FDG PET/CT is a valuable tool for optimal early assessment of treatment response in radiofrequency-ablated primary and secondary liver and lung tumors, as well as benign bone tumors such as osteoid osteoma.

TL;DR: The studies indicate frequent overexpression of apoptosis regulators bcl-2, bax and p53 proteins in oral cancers, and a subset of oral lesions, representing early events in oral carcinogenesis.
Abstract: Deregulation of oncogenes and tumor suppressor genes involved in apoptosis has been associated with tumor development and progression. To investigate the involvement of apoptosis regulating proteins in oral cancer in Indian patients, primarily associated with chewing tobacco habits, immunohistochemical expression of bcl-2 and bax was examined in 63 oral squamous cell carcinomas, and 31 putative premalignant lesions. Our studies revealed overexpression of tumor specific cytoplasmic bcl-2 in 56% and bax in 43% oral cancers. The oral cancers in the Indian patients are preceded by premalignant oral lesions; hence oral lesions were examined for bcl-2 and bax expression. We observed aberrant expression of bcl-2 in 16% oral lesions comprising leukoplakias and SMF and bax in 55% oral lesions. We have already reported, p53 expression in these oral cancers and lesions. It was noteworthy that 30% oral cancers demonstrated a p53+bcl2+ pattern, and 14% samples exhibited p53+bcl2+bax+ pattern. However, none of the oral lesions showed concurrent deregulation of p53 and bcl-2 or all the three genes. Interestingly 45% oral lesions were p53-bax+ as compared to 18% oral cancers; while 39% oral lesions were bcl2-bax+ as compared to 14% oral cancers, indicating overexpression of bax in oral lesions, in the absence of p53 and bcl-2 proteins. Significant correlation was observed between positive nodal status and bcl2+ (p=0.047) and p53+bcl-2+ (p=0.01) in oral cancers. Kaplan Meier survival analysis showed significantly (p=0.059) higher survival in patients with p53-oral tumors than with p53+ tumors. Our studies thus indicate frequent overexpression of apoptosis regulators bcl-2, bax and p53 proteins in oral cancers, and a subset of oral lesions, representing early events in oral carcinogenesis. The aberrant bcl-2 expression and loss of p53 function observed, may play an important role in the tumorigenesis of oral cancers by allowing escape from apoptosis and enabling additional genetic alterations to accrue.

TL;DR: A case of microsporidial infection in a female patient with chronic myeloid leukemia undergoing allogeneic bone marrow transplantation is reported, suggesting that transplant patients are another group of patients who are susceptible to this group of opportunistic pathogens.
Abstract: Very few cases of human microsporidial infection have been reported The advent of AIDS has changed this There is increasing recognition that microsporidia are important opportunistic pathogens However, the number of cases reported in the non-HIV population is small We report here a case of microsporidial infection in a female patient with chronic myeloid leukemia undergoing allogeneic bone marrow transplantation There was also an associated fungal infection The diagnosis could be reached only after postmortem and was confirmed by electron micrography We suggest that transplant patients are another group of patients who are susceptible to this group of opportunistic pathogens
