TL;DR: ABVD is associated with relatively better preservation of gonadal function and three patients treated with ABVD fathered children post-therapy.
Abstract: To assess the effect of combination chemotherapy with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) on gonadal function in patients treated for Hodgkin's disease, we assessed 38 male patients with Hodgkin's disease who were >15 years of age and in complete remission for the development

TL;DR: Salivary specificity is noted for three bacteria, namely, Capnocytophaga gingivalis, P. melaninogenica, and Streptococcus mitis in oral cancer patients, making these species salivary markers for the early detection of oral cancers and thus improving the survival rate significantly.
Abstract: Despite the widening interest in the possible association between bacteria and different stages of cancer development, our knowledge in its relation to oral cancers remains inadequate. The aim of this review article is to derive a better understanding on the role of various micro-organisms in the etiogenesis of oral cancers through all the available data on the pubmed. Different bacteria have been proposed to induce carcinogenesis either through induction of chronic inflammation or by interference, either directly or indirectly, with eukaryotic cell cycle and signaling pathways, or by metabolism of potentially carcinogenic substances like acetaldehyde causing mutagenesis. Studies have shown diversity of isolated bacterial taxa between the oral cancer tissue specimens and the control, with Exiguobacterium oxidotolerans, Prevotella melaninogenica, Staphylococcus aureus and Veillonella parvula being specific for tumorogenic tissues. Most isolates are saccharolytic and acid tolerant. Streptococcus anginosus, commonly linked with esophageal and pharyngeal cancers, is not of significance in oral cancers. Similarly, significant salivary specificity is noted for three bacteria, namely, Capnocytophaga gingivalis, P. melaninogenica, and Streptococcus mitis in oral cancer patients, making these species salivary markers for the early detection of oral cancers and thus improving the survival rate significantly. Also, such high degree of bacterial specificity in oral cancers has also provoked the designing of new treatment options for cancer prevention by way of vaccine delivery. However, for the success of these steps, a deeper exploration into this subject with a greater understanding is warranted.

TL;DR: Nineteen patients with solitary metastatic lesions from renal cell carcinoma, 5 synchronous and 14 metachronous, were seen at the Tata Memorial Hospital over a 7 year period between 1981 and 1987, with a mean metastatic interval of 31.2 months.
Abstract: Nineteen patients with solitary metastatic lesions from renal cell carcinoma, 5 synchronous and 14 metachronous, were seen at the Tata Memorial Hospital over a 7 year period between 1981 and 1987 The mean metastatic interval for the metachronous lesions was 312 months The commonest sites of metastases were bone, lung, and liver The solitary nature of the metastasis was confirmed by appropriate investigations All patients underwent nephrectomy for the primary kidney lesion The metastatic lesions were treated with intent of cure Only 1 patient with synchronous metastasis survived for 2 years and none survived 5 years while in the metachronous metastasis group, the estimated overall survival was 50% at 2 years and 25% at 5 years The patients with a long metastasis-free interval were found to have a better survival The patients with liver metastasis did poorly as compared to those with metastases at other sites The stage of the disease also had a bearing on the survival

TL;DR: The promising role of integrated FDG-PET/CT in the overall management of this serious malignancy is explored and the feasibility of a new method of image segmentation based on an iterative thresholding algorithm is discussed, which permits definition of the boundaries of lesions based on PET images alone.
Abstract: Increasingly, integrated positron emission tomography-computed tomography (PET/CT) imaging is playing a crucial role in the assessment of patients with known or suspected malignant pleural mesothelioma (MPM). Based on the data reported in the literature, this combined modality is likely to become the instrument of choice for examining patients of MPM. The research on this subject has focused on the following five domains: (1) differentiation of MPM from other benign pleural diseases, (2) preoperative staging for the selection of appropriate candidates for surgery, (3) evaluation for therapy response and post-treatment surveillance for recurrence, (4) prognostication based upon the intensity of 2-deoxy-2-[18F]fluoro-d-glucose (FDG) uptake, and (5) planning of radiotherapy. These represent the bases for critical decision making in the management of mesothelioma, and FDG-PET/CT offers potential advantages over conventional CT imaging and thus can play a pivotal role in this regard. Optimal characterization of this potentially fatal disease with a high negative predictive value for MPM, superior capability for cancer staging initially and at the later course of disease, and ability for measuring therapeutic response and the precise determination of the target volume for radiotherapy planning represent distinct advantages of this promising molecular imaging tool. In this communication, we have explored the promising role of integrated FDG-PET/CT in the overall management of this serious malignancy. From the available data, the major role of PET-CT at present appears to be in the preoperative disease staging, response to treatment assessment, and post-treatment disease surveillance of MPM. In all these three areas, PET-CT convincingly shows better results than conventional anatomical imaging alone and thereby can aid in exploring novel therapeutic approaches. Disease prognosis and radiotherapy planning are evolving areas where this modality has demonstrated significant promise, but this has to be investigated further. The differentiating of MPM from benign pleural disease is a challenging issue; though in limited studies, it has shown promising results, single standardized uptake value (SUV) cutoff technique cannot be the optimal way for this purpose. Dual time point and delayed imaging helps further in this setting; however, more data require to be accrued in this area. We, in this review, have also discussed the feasibility of a new method of image segmentation based on an iterative thresholding algorithm, which permits definition of the boundaries of lesions based on PET images alone to provide lesional metabolically active tumor volumes, lesional partial volume corrected SUV (PVC-SUV) measurements, lesional PVC metabolic burden (PVC-MB) (calculated as the product of lesional MVP and lesional PVC-SUV), and whole body metabolic burden (WBMB) (calculated as the sum of lesional PVC-MB of all lesions). This global disease assessment, we believe, will be the way forward for assessing this malignancy with a non-invasive imaging modality.

TL;DR: The panel concluded that it is useful to combine different techniques instead of relying on a single one and to adapt the “package” of interventions to the condition of the patient.
Abstract: While the pulmonary artery catheter (PAC) is still interesting in specific situations, there are many alternatives. A group of experts from different backgrounds discusses their respective interests and limitations of the various techniques and related measured variables. The goal of this review is to highlight the conditions in which the alternative devices will suffice and when they will not or when these alternative techniques can provide information not available with PAC. The panel concluded that it is useful to combine different techniques instead of relying on a single one and to adapt the “package” of interventions to the condition of the patient. As a first step, the clinical and biologic signs should be used to identify patients with impaired tissue perfusion. Whenever available, echocardiography should be performed as it provides a rapid and comprehensive hemodynamic evaluation. If the patient responds rapidly to therapy, either no additional monitoring or pulse wave analysis (allowing continuous monitoring in case potential degradation is anticipated) can be applied. If the patient does not rapidly respond to therapy or complex hemodynamic alterations are observed, pulse wave analysis coupled with TPTD is suggested.
