Abstract Title: 

The effect of cryotherapy on fibromyalgia: a randomised clinical trial carried out in a cryosauna cabin.

Abstract: 

Evidence of symptomatic treatment for fibromyalgia (FM) is very low. Whole body cryotherapy (WBC) modulates different neurotransmitters, which might have a role in pain alleviation and could exert an effect on FM. Our aim was to evaluate the efficacy of WBC for the control of pain and impact of disease in FM. For this we run an open, randomized, crossover trial of Cryosense TCT™ cabin vs rest. Patients with FM according to ACR criteria were recruited consecutively from general practices. Trial endpoints were change (∆) in pain after 2 and 4 weeks, measured by a visual analogue scale (VAS), ∆ burden of disease, evaluated by the Fibromyalgia Impact Questionnaire (FIQ), and severity of FM, measured by the Combined Index of Severity of Fibromyalgia (ICAF). Within group differences, sequence and period effects were tested with Student's t or Mann-Whitney U tests. Multiple linear regression models were used to adjust effect by baseline differences between groups. Sixty patients were included in the trial. A period effect was noted, with residual effect of WBC; therefore, only results from the first sequence were analysed. ∆VAS pain, ∆FIQ and ∆ICAF scores were significantly larger in the WBC group after the first period (3.0 vs 0.3 in ∆VAS pain; 32.1 vs 0.4 in ∆FIQ; 13.7 vs 0.07 in ∆ICAF; all p

Abstract Title: 

Cryotherapy vs trichloroacetic acid 90% in treatment of common warts.

Abstract: 

INTRODUCTION: Common warts are hyperkeratotic, benign cutaneous growths caused by types 1, 2, and 7 Human papilloma viruses. Different modalities are available to treat warts. Cryotherapy is one of the most common and effective treatments for common warts. Trichloroacetic acid (TCA), in high concentrations, can be used as a therapeutic modality.OBJECTIVES: The aim of this study is to compare the efficacy and safety of cryotherapy using liquid nitrogen (spray method) versus trichloroacetic acid 90% in treatment of common warts.PATIENTS AND METHODS: Thirty-five patients with 414 common warts, from the Dermatology outpatient clinic, Assiut University Hospital, were enrolled in this study. We used two techniques for the treatment of common warts. The lesions in each patient were divided into two groups (A and B), group A treated by cryotherapy while group B treated by trichloroacetic acid (TCA) 90%.RESULTS: There was significant decrease in the size of the warts in both groups. There were statistically significant better results among group A than group B regarding the mean percentage of improvement (90.11 ± 27.92 vs 26.19 ± 42.93, respectively; P

Abstract Title: 

Cryotherapy in the management of premalignant and malignant conditions of the esophagus.

Abstract: 

Endoscopic cryotherapy is a relatively new thermal ablative modality used for the treatment of neoplastic lesions of the esophagus. It relies on cycles of rapid cooling and thawing to induce tissue destruction with a cryogen (liquid nitrogen or carbon dioxide) leading to intra and extra-cellular damage. Surgical treatment was once considered the standard therapeutic intervention for neoplastic diseases of the esophagus and is associated with considerable rates of morbidity and mortality. Several trials that evaluated cryotherapy in Barrett's esophagus (BE) associated neoplasia showed reasonable efficacy rates and safety profile. Cryotherapy has also found applications in the treatment of esophageal cancer, both for curative and palliative intent. Cryotherapy has also shown promising results as salvage therapy in cases refractory to radiofrequency ablation treatment. Cryoballoon focal ablation using liquid nitrogen is a novel mode of cryogen delivery which has been used for the treatment of BE with dysplasia and squamous cell carcinoma. Most common side effects of cryotherapy reported in the literature include mild chest discomfort, esophageal strictures and bleeding. In conclusion, cryotherapy is an effective and safe method for the treatment of esophageal neoplastic processes, ranging from early stages of low grade dysplasia to esophageal cancer.

Abstract Title: 

Cryotherapy for nodal metastasis in NSCLC with acquired resistance to immunotherapy.

Abstract: 

Novel approaches with checkpoint inhibitors in immunotherapy continue to be essential in the treatment of non-small cell lung cancer (NSCLC). However, the low rate of primary response and the development of acquired resistance during the immunotherapy limit their long-term effectiveness. The underlying cause of acquired resistance is poorly understood; potential management strategies for patients with acquired resistance are even less clear. Here, we report the case of a 75-year-old female smoker with cough, fatigue, and weight loss that was found to have an 8.6 cm right upper lobe lung lesion with local invasion, adenopathy, and a malignant pericardial effusion. This lesion was biopsied and identified to be cT3N3M1b squamous cell cancer of the lung without any recognizable PD-L1 expression on tumor cells. For her metastatic NSCLC, the patient underwenttwo lines of conventional chemotherapy before initiation of combination immunotherapy with an anti-PD-L1 and anti-CTLA-4 antibody. Though she initially achieved a response, she thereafter progressed and developed immunotherapy resistant lymph nodal metastasis. While cervical lymph nodes could be surgically removed, another metastasis in an aortocaval area required a more sensitive therapy like thermal ablation. The aortocaval node was partially treated with a single treatment of cryotherapy and demonstrated durable complete response. Cryotherapy for checkpoint immunotherapy resistant metastasis appears to be a safe and feasible treatment for treating metastatic disease in non-small cell lung cancer. The prospect of cryotherapy adjuvancy may enable local control of metastatic disease after initial response to immune checkpoint immunotherapy and may impact on overall outcomes.

Abstract Title: 

3-min whole body cryotherapy/cryostimulation after training in the evening improves sleep quality in physically active men.

Abstract: 

Exercise training during evening may disturb sleep patterns and hinder recovery process. The present study aimed to examine the effect of whole body cryotherapy (WBC) exposure after training in the evening on sleep quality and night heart rate variability (HRV). A total of 22 physically active men were randomized to undergo either WBC (3-min at -40°C, wind speed of 2.3 m s) or passive recovery (control) following an evening training consisting of 25 min of continuous running at 65% of the maximal aerobic speed (MAS) followed by intermittent running at 85% of the MAS. Each night following the training, the number of movements and HRV during sleeping time were recorded. The next morning, subjective sleep quality and perceived pain were assessed using Spiegel questionnaire and a visual analogue scale, respectively. The number of movements during the night following WBC was significantly reduced (

Abstract Title: 

Oral cryotherapy for prophylaxis of oral mucositis caused by docetaxel, cisplatin, and fluorouracil chemotherapy for esophageal cancer.

Abstract: 

BACKGROUND: Chemotherapy, including preoperative chemotherapy, plays an important role in the treatment of esophageal cancer. However, although docetaxel, cisplatin, and fluorouracil (DCF) therapy has a powerful antitumor effect, the associated adverse events make it difficult to maintain the patient's general condition. Oral mucositis is an important adverse effect of chemotherapy, and its severity, frequency, and impact on patient quality of life should not be underestimated. This study evaluated the role of oral cryotherapy for prophylaxis of oral mucositis caused by DCF therapy.METHODS: We retrospectively examined the incidence and severity of adverse events, including mucositis, in 72 patients with esophageal cancer treated with DCF. Fifty-eight patients received cryotherapy during docetaxel administration and 14 received no cryotherapy.RESULTS: The incidence of mucositis of all grades and grade 3 was significantly lower in the cryotherapy group compared with the no-cryotherapy group (24.1% vs. 71.4%, P

Abstract Title: 

Combining Thermotherapy with Cryotherapy for Efficient Eradication of Apple stem grooving virus from Infected In-vitro-cultured Apple Shoots.

Abstract: 

Apple stem grooving virus (ASGV), a difficult-to-eradicate virus from apple propagative materials, causes serious damage to apple production. The use of virus-free plants has been and is an effective strategy for control of plant viral diseases. This study aimed to eradicate ASGV from virus-infected in-vitro-cultured shoots of four apple cultivars and one rootstock by combining thermotherapy with cryotherapy. In vitro stock shoots infected with ASGV were thermo-treated using an alternating temperature of 36°C (day) and 32°C (night). Shoot tips were excised from the treated stock shoots and subjected to cryotherapy. Results showed that, although thermotherapy did not influence shoot survival rates, it reduced shoot growth and proliferation of in vitro shoots. Shoot regrowth rates decreased while virus eradication frequencies increased in cryo-treated shoot tips as time durations of thermotherapy increased from 0 to 6 weeks. Shoot regrowth and frequency of virus eradication were positively and negatively correlated, respectively, with the size of shoot tips. The protocol established here yieldedshoot regrowth rates and virus eradication frequencies of 33 to 76% and 30 to 100%, respectively, in the four apple cultivars and one rootstock. Thermotherapy altered virus distribution patterns, subsequently resulting in production of a larger virus-free area in the thermo-treated shoot tips. Manycells in the top layers of apical dome and some cells in the youngest leaf primordia survived in cryo-treated shoot tips; these cells were most likely free of virus infection. Thus, plants regenerated from the procedure of combining thermotherapy with cryotherapy were free of ASGV, as judged by reverse-transcription polymerase chain reaction. To the best of our knowledge, this is the widest-spectrum technique reported thus far for the production of ASGV-free plants and provides a novel biotechnology for the production of virus-free plants in Malus spp.

Abstract Title: 

Late vitamin K deficiency bleeding after intramuscular prophylaxis at birth: a case report.

Abstract: 

We report the case of a 6-week-old female who presented an intracranial hemorrhage due to late vitamin K deficiency bleeding (VKDB). No other evident bleeding sites were present at the moment of diagnosis. Intramuscular vitamin K (1 mg) was administered at birth. She was exclusively breast-fed. No other risk factors for VKDB were detected. Low levels of vitamin K-dependent coagulation factors and their normalization after vitamin K administration confirmed the diagnosis of late VKDB. The present case suggests potential risks related to a single dose of intramuscular vitamin K at birth.

Abstract Title: 

Inadvertent Methylergonovine Administration to a Neonate.

Abstract: 

BACKGROUND Methylergonovine is an ergot alkaloid used to treat post-partum hemorrhage secondary to uterine atony. Mistaking methylergonovine for vitamin K with accidental administration to the neonate is a rare iatrogenic illness occurring almost exclusively in the delivery room setting. Complications of ergot alkaloids in neonates include respiratory depression, seizures, and death. CASE REPORT A term infant was inadvertently given 0.1 mg of methylergonovine intramuscularly in the right thigh. The error was only noted when the vial of medication was scanned, after administration, identifying it as methylergonovine rather than vitamin K. The local poison center was notified, and the infant was transferred to the neonatal intensive care unit for observation. Two hours after transfer, the infant was noted to have oxygen desaturations and required oxygen via nasal cannula. Supplemental oxygen was continued for 4 hours until the neonate was able to maintain normal oxygen saturations in room air. Feeding was started by 10 hours of life, and the infant was discharged home in good condition after a 72-hour stay without further complications. CONCLUSIONS Because of the potential for serious adverse events, vigilance is required to prevent accidental administration of methylergonovine to the neonate as a result of possible confusion with vitamin K in the early post-partum period.

Abstract Title: 

Childhood cancer, intramuscular vitamin K, and pethidine given during labour.

Abstract: 

OBJECTIVE: To assess unexpected associations between childhood cancer and pethidine given in labour and the neonatal administration of vitamin K that had emerged in a study performed in the 1970 national birth cohort.DESIGN AND SETTING: 195 children with cancer diagnosed in 1971-March 1991 and born in the two major Bristol maternity hospitals in 1965-87 were compared with 558 controls identified from the delivery books for the use of pethidine during labour and administration of vitamin K.MAIN OUTCOME MEASURES: Odds ratios for cancer in the presence of administration of pethidine or of intramuscular vitamin K. Both logistic regression and Mantel-Haenszel techniques were used for statistical analyses.RESULTS: Children of mothers given pethidine in labour were not at increased risk of cancer (odds ratio 1.05, 95% confidence interval 0.7 to 1.5) after allowing for year and hospital of delivery, but there was a significant association (p = 0.002) with intramuscular vitamin K (odds ratio 1.97, 95% confidence interval 1.3 to 3.0) when compared with oral vitamin K or no vitamin K. There was no significantly increased risk for children who had been given oral vitamin K when compared with no vitamin K (odds ratio 1.15, 95% confidence interval 0.5 to 2.7). These results could not be accounted for by other factors associated with administration of intramuscular vitamin K, such as type of delivery or admission to a special care baby unit.CONCLUSIONS: The only two studies so far to have examined the relation between childhood cancer and intramuscular vitamin K have shown similar results, and the relation is biologically plausible. The prophylactic benefits against haemorrhagic disease are unlikely to exceed the potential adverse effects from intramuscular vitamin K. Since oral vitamin K has major benefits but no obvious adverse effects this could be the prophylaxis of choice.
