Cryotherapy in extra-abdominal desmoid tumors: A systematic review and meta-analysis

Introduction Desmoid tumor is a locally-invasive neoplasm that causes significant morbidity. There is recent interest in cryotherapy for treatment of extra-abdominal desmoid tumors. This systematic review assesses evidence on safety and efficacy of cryotherapy in the treatment of extra-abdominal desmoid tumors. Materials and methods The systematic review was conducted with reference to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Literature search was performed using MEDLINE and the Cochrane Central Register of Controlled Trials. 9 full text papers were reviewed and meta-analysis was performed for measures of safety, efficacy and symptom relief. Results The estimated pooled proportion of major and minor complications was 4.2% (95% CI, 1.8–9.6; I 2 = 0%) and 10.2% (95% CI, 5.7–17.8; I 2 = 0%) respectively. The estimated pooled proportion of non-progressive disease rate of all studies was 85.8% (95% CI, 73.4–93.0; I 2 = 32.9%). The estimated progression free survival rate at 1 year was 84.5% (95% CI:74.6–95.8) and 78.0% at 3 years (95% CI: 63.8–95.3). As for pain control, the estimated pooled proportion of patients with decrease in visual analogue scale (VAS) > = 3 for those with VAS > = 3 before treatment for 2 studies was 87.5% (95% CI, 0.06–100; I 2 = 71.5%) while 37.5% to 96.9% of patients were reported to have experienced partial or complete symptom relief in the other studies. Conclusion Cryotherapy is a safe and effective treatment modality for extra-abdominal desmoid tumors with efficacy similar to those treated with traditional strategies in the short to medium term.

DFMO Improves Survival and Increases Immune Cell Infiltration in Association with MYC Downregulation in the Pancreatic Tumor Microenvironment

Pancreatic ductal adenocarcinoma (PDAC) has an extremely poor five-year survival rate of less than 10%. Immune suppression along with chemoresistance are obstacles for PDAC therapeutic treatment. Innate immune cells, such as tumor-associated macrophages, are recruited to the inflammatory environment of PDAC and adversely suppress cytotoxic T lymphocytes. KRAS and MYC are important oncogenes associated with immune suppression and pose a challenge to successful therapies. Here, we targeted KRAS, through inhibition of downstream c-RAF with GW5074, and MYC expression via difluoromethylornithine (DFMO). DFMO alone and with GW5074 reduced in vitro PDAC cell viability. Both DFMO and GW5074 showed efficacy in reducing in vivo PDAC growth in an immunocompromised model. Results in immunocompetent syngeneic tumor-bearing mice showed that DFMO and combination treatment markedly decreased tumor size, but only DFMO increased survival in mice. To further investigate, immunohistochemical staining showed DFMO diminished MYC expression and increased tumor infiltration of macrophages, CD86+ cells, CD4+ and CD8+ T lymphocytes. GW5074 was not as effective in modulating the tumor infiltration of total CD3+ lymphocytes or tumor progression and maintained MYC expression. Collectively, this study highlights that in contrast to GW5074, the inhibition of MYC through DFMO may be an effective treatment modality to modulate PDAC immunosuppression.

A REVIEW ON THE PHARMACODYNAMICS OF BASTI KARMA

ABSTRACT Basti Karma is the most widely used and highly effective treatment modality in Panchakarma. Though Basti is specially indicated for Vatika diseases but it is mentioned in vitiation of all the Vata, Pitta, Kapha, Rakta Doshika disorders. Correctly given Basti will stay in the Pakawashaya, Shroni, Nabhi and Adhobhaga. Basti Dravya will reach the entire Srotasa, in view of its Veerya and produces alleviating action Shamanadi karmas. References regarding Basti Karmuktwa were collected from various classical and Ayurveda published works, published research papers from Pub Med, Google Scholar and compilation was done. Concept of Pharmacodynamics of Basti was studied in detail. Basti is most often recommended practice in Vata Roga Chikitsa. Most of the previous studies have emphasized on the importance of Basti in Vata vyadhis; however there were limited studies carried out on pharmacodynamics of Basti only. Pharmacodynamics outcome of Basti Karma may be due to functioning of the one or more effect of different mechanism.

Effects of 1 MHz Therapeutic Ultrasound on Limb Blood Flow and Microvascular Reactivity: A Randomized Pilot Trial

A randomized, double-blind, placebo-controlled, cross-over study where continuous therapeutic ultrasound (CUS; at 0.4 W/cm2), pulsed therapeutic ultrasound (PUS; at 20% duty cycle, 0.08 W/cm2), both at 1 MHz, and placebo (equipment on, no energy provided) were randomized and applied over the forearm of the non-dominant arm for 5 min in 10 young, healthy individuals. Absolute and peak forearm blood flow (FBF) were measured via Venous Occlusion Plethysmography. FBF was measured before, halfway, and after (immediately and 5 min after) the therapeutic ultrasound (TUS) intervention. Post-ischemic peak FBF was measured 10 min before and 10 min after the TUS intervention. A two-way repeated measures ANOVA (group × time) was selected to assess differences in FBF before, during, and after TUS treatment, and for peak FBF before and after TUS treatment. FBF increased 5 min after TUS in CUS compared to placebo (2.96 ± 1.04 vs. 2.09 ± 0.63 mL/min/100 mL of tissue, p < 0.05). PUS resulted in the greatest increase in Peak FBF at 10 min after US (Δ = 3.96 ± 2.02 mL/min/100 mL of tissue, p = 0.06). CUS at 1 MHz was an effective treatment modality for increasing FBF up to 5 min after intervention, but PUS resulted in the greatest increase in peak FBF at 10 min after intervention.

Proposal for Establishing a New Radiotherapy Facility

Cancer is a growing burden globally. Radiotherapy has proven to be a critical and cost-effective treatment modality for a cure in greater than 50% of cancer patients. There are numerous obstacles and challenges in establishing new radiotherapy facilities and programs, especially in low- and middle-income countries. It is known that the clinical aspect, as well as procedure related to the physical and technical aspect of patient treatment, needs to be subjected to careful planning in order to ensure safe and high-quality radiotherapy. This process required the engagement of various professionals from different backgrounds.This chapter aims to define radiotherapy value, assessing a radiation facility’s clinical, infrastructure, and resources need to establish a new radiotherapy facility.

Factors influencing failure to undergo interval cholecystectomy after percutaneous cholecystostomy among patients with acute cholecystitis: a retrospective study

Background Percutaneous cholecystostomy (PC) with interval cholecystectomy is an effective treatment modality in high-risk patients with acute cholecystitis. However, some patients still fail to undergo interval cholecystectomy after PC, with the reasons rarely reported. Hence, this study aimed to explore the factors that prevent a patient from undergoing interval cholecystectomy. Methods Data from patients with acute cholecystitis who had undergone PC from January 1, 2017 to December 31, 2019 in our hospital were retrospectively collected. The follow-up endpoint was the patient undergoing cholecystectomy. Patients who failed to undergo cholecystectomy were followed up every three months until death. Univariate and multivariate analyses were performed to analyze the factors influencing failure to undergo interval cholecystectomy. A nomogram was used to predict the numerical probability of non-interval cholecystectomy. Results Overall, 205 participants were identified, and 67 (32.7%) did not undergo cholecystectomy during the follow-up period. Multivariate analysis revealed that having a Tokyo Guidelines 2018 (TG18) grade III status (odds ratio [OR]: 3.83; 95% confidence interval [CI]: 1.27–11.49; p = 0.017), acalculous cholecystitis (OR: 4.55; 95% CI: 1.59–12.50; p = 0.005), an albumin level < 28 g/L (OR: 4.15; 95% CI: 1.09–15.81; p = 0.037), and a history of malignancy (OR: 4.65; 95% CI: 1.62–13.37; p = 0.004) were independent risk factors for a patient’s failure to undergo interval cholecystectomy. Among them, the presence of a history of malignancy exhibited the highest influence in the nomogram for predicting non-interval cholecystectomy. Conclusions Having a TG18 grade III status, acalculous cholecystitis, severe hypoproteinemia, and a history of malignancy influence the failure to undergo cholecystectomy after PC in patients with acute cholecystitis.

Presentation, Diagnosis and Management of Innominate Artery Thromboembolism

Purpose: Acute thromboembolic disease of the innominate artery (IA) poses a unique set of therapeutic challenges, owing to its contribution to both the cerebral and upper extremity circulation, and risks of distal embolization via the carotid and subclavian arteries, respectively. Herein, we present a 74-year-old female who presents with acute IA thrombus treated successfully with right axillary and common carotid exposure and aspiration catheter-directed mechanical thrombectomy (CDT). Furthermore, an emerging use of CDT and its application in acute thromboembolism are outlined. Case report: A 74-year-old female with history of right lung transplant for pulmonary fibrosis with severe pulmonary hypertension, and stage IIIA left lung adenocarcinoma status post left lower lobectomy undergoing adjuvant chemotherapy presented with acute IA thrombus and right-sided stroke. She was treated successfully with right axillary and common carotid exposure and aspiration CDT. Computed tomography angiography performed 1 month postoperatively confirmed patent IA with no evidence of residual or recurrent thrombus. Conclusion: There are currently no standard guidelines on the management of acute IA thromboembolism, with mostly individual cases reported in the literature describing this rare entity. Nevertheless, this unique clinical entity mandates expeditious diagnostic and therapeutic approaches in order to avoid permanent neurologic deficits from distal embolization. Our case demonstrates that aspiration CDT may be an effective treatment modality for patients with acute IA thrombus.

Successful management of bilateral internal carotid artery fusiform giant aneurysms in a patient with intimal fibroplasia using multiple flow diverters: With long-term imaging follow up

The authors report a rare case of sequentially developed bilateral internal carotid artery (ICA) fusiform giant aneurysms in a patient with pathologically confirmed intimal fibroplasia. Both ICA fusiform aneurysms were treated with multiple flow diverter insertion and were well-managed over the past 5.5 years of follow-up. The development of aneurysms in this rare disease entity appears to be a lifelong process based on the authors’ observations in serial angiographic follow-up studies. Reconstruction therapy using flow-diverting stents in this unique condition may be a safe and effective treatment modality.
