Background: Cannabidiol (CBD)-based treatments for several diseases, including Tourette’s

syndrome, multiple sclerosis, epilepsy, movement disorders and glaucoma, are proving to be beneficial and the  scientific clinical background of the drug is continuously evolving. 

Objectives: To investigate the short-term effect of CBD-enriched hemp oil for relieving symptoms and improving the life quality (QOL) in young girls with adverse drug effects (ADRs) following human papillomavirus (HPV) vaccine. 

Methods: In this anecdotal, retrospective, “compassionate-use”, observational, open-label study, 12 females (age 12–24 years) with severe somatoform and dysautonomic syndrome following HPV vaccination were given sublingual CBD-rich hemp oil drops, 25 mg/kg per day supplemented by 2–5 mg/ml CBD once a week until a maximum dose of 150 mg/ml CBD per day was reached over a 3 month period. Patients’ quality of life was evaluated using the medical outcome short-form health survey questionnaire (SF-36).

Results: Two patients dropped out due to iatrogenic adverse events and another two patients stopped the treatment early due to lack of any improvement. SF-36 showed significant benefits in the physical component score (P < 0.02), vitality (P < 0.03) and social role functioning (P < 0.02) after the treatment. The administration of hemp oil also significantly reduced body pain according to the SF-36 assessment. No significant differences from the start of treatment to several months post-treatment were detected in role limitations due to emotional reactions (P = 0.02).

Conclusions: This study demonstrated the safety and tolerability of CBD-rich hemp oil and the primary efficacy endpoint. Randomized controlled trials are warranted to characterize the safety profile and efficacy of this compound.

A flowering plant of variegated ingredients and psychoactive qualities, cannabis has long been used for medicinal and recreational purposes. Currently, cannabis is approved in several countries for indications of symptomatic alleviation. However, limited knowledge on the benefits and risks precludes inclusion of cannabis in standard treatment guidelines. This review provides a summary of the available literature on the use of cannabis and cannabinoid-based medicines in palliative oncology. Favorable outcomes are demonstrated for chemotherapy-induced nausea and vomiting and cancer-related pain, with evidence of advantageous neurological interactions. Benefit in the treatment of anorexia, insomnia and anxiety is also suggested. Short- and long-term side effects appear to be manageable and to subside after discontinuation of the drug. Finally, cannabinoids have shown anti-neoplastic effects in preclinical studies in a wide range of cancer cells and some animal models. Further research is needed before cannabis can become a part of evidence-based oncology practice.

Background: Burn scar reconstruction is extremely challenging, even for the most proficient reconstructive surgeon. Within the arsenal of tools at the plastic surgeon’s disposal, tissue expansion provides an efficient modality for reconstruction despite the reported complication rates. 

Objectives: To critically review our experience with tissue expansion for burn scar reconstruction, comparing particularly the adult and pediatric populations.

Methods: We conducted a retrospective study of the outcomes of patients who underwent burn scar reconstruction with tissue expansion at Hadassah Medical Center between January 2003 and July 2012. The data included patient age, anatomical site of expansion, number of procedures, and associated complications. The outcomes of the above-mentioned populations were also compared with those in a control group of patients undergoing reconstruction with tissue expansion for indications other than burn scars. 

Results: Sixty-seven tissue expansion procedures were carried out in 50 patients, 42 in the pediatric population (< 16 years of age) and 25 in the adult population. Complications were observed in 10 of the 42 pediatric procedures (23.8%) and in 3 of the 25 adult procedures (12%). This difference was found to be statistically significant. When the complication rate for each population was compared to its control group (tissue expansion for indications other than burn scar reconstruction, such as reconstruction for motor vehicle accident scarring, congenital nevi, or vascular malformations), no statistically significant difference was found between them (complication rates 19.8% and 12.5%, respectively). Furthermore, there was no statistically significant difference in complication rates between the different anatomical areas of expansion within both populations undergoing burn scar reconstruction. Most of the complicated cases completed successful reconstruction.

Conclusions: Tissue expansion is a useful surgical tool in post-burn scar reconstruction, both in the adult and pediatric populations and in all anatomic sites, despite consistently high complication rates, especially in the pediatric population. This complication rate is not higher than in patients undergoing tissue expansion for indications other than burn scar reconstruction.

Background: Hyperplastic polyps (HPs) of the colon are the most common colorectal polyps. Metabolic syndrome components such as obesity and hyperlipidemia are considered the most common etiological factors for HPs as well contributing to the pathogenesis of fatty liver disease. Objectives: To determine the possible association between biopsy-proven steatohepatitis and hyperplastic colonic polyps. 

Methods: This retrospective cohort observational study conducted at the Holy Family Hospital in Nazareth, Israel, included subjects who underwent screening colonoscopy over a 2 year period. Data were extracted from the patient charts and included demographics, anthropometric measurements, vital signs, underlying diseases, medical therapy, laboratory data, and results of the liver biopsy. The colonoscopy report and pathological report of each extracted polyp were also evaluated.

Results: A total of 223 patients were included in the study: 123 patients with biopsy-proven non-alcoholic steatohepatitis (NASH) and 100 patients without NASH who served as the control. Fourteen colonic adenomas (11% of patients) were found in the NASH group vs. 16 (16%) in the control group (P = 0.9); 28 HPs were found in the NASH group (22.7%) vs. 8 in the control group (8%) (P < 0.05). The multivariate analysis, after adjusting for, age, C-reactive protein and smoking, showed that the presence of NASH (OR 1.69, 95%CI 1.36–1.98, P < 0.01) was associated with increased risk for HP. 

Conclusions: Our study found an association between biopsy-proven steatohepatitis and the burden of hyperplastic polyp.

Background: In recent decades cataract surgery has shifted slowly from public hospitals to ambulatory surgery centers, demonstrating changes in the profile of patients presenting to public hospitals for cataract surgery. These changes may potentially affect the complexity of surgeries, their volume, resident training, and perhaps also visual outcomes and patient satisfaction. 

Objectives: To assess the changes in the medical and demographic characteristics of patients undergoing cataract surgery in a public hospital over a period of 15 years. 

Methods: We retrospectively reviewed the records of patients undergoing preoperative assessment before cataract surgery. Records for the period October 2000 to January 2001 (100 patients), October 2006 to January 2007 (100 patients), and October 2013 to January 2014 (150 patients) were assessed for demographic, systemic and ocular related parameters. 

Results: There was a significant increase in the average age of patients (70.4, 72.4, 73.9 years, P = 0.026), with a significant increase in the percentage of patients of Arab ethnicity (17%, 11%, 28.7%, P = 0.002), and concomitant systemic co-morbidities (38%, 46%, 64.7%, P < 0.0001). There was an increase in the percentage of patients with narrow palpebral fissures (0%, 2%, 8%, P = 0.003), deep-set eyes (2%, 4%, 18%, P < 0.0001), dense nuclear sclerotic cataract (38%, 34.4%, 56.9%, P = 0.001), and a significant increase in the percentage of patients taking alpha-blocking medications (0%, 8%, 10.7 %, P = 0.004).

Conclusions: Patients presenting for cataract surgery in 2013 compared to those in earlier periods are older, sicker and have more ocular conditions potentially affecting cataract surgery outcomes, patient satisfaction and residents' training.

Background: More than 90% of all thyroid cancers are differentiated thyroid carcinomas (DTC) with a 10 year survival rate greater than 90%. The commonly used risk stratification systems for DTC include: European Organization for Research and Treatment of Cancer (EORTC), AGES (Age, histologic Grade, Extent of tumor, Size), AMES (Metastasis) and MACIS (Completeness of resection, local Invasion). Other systems are also utilized. Several new factors that may be involved in DTC risk stratification have emerged in recent studies, with other "traditional" factors being challenged. 

Objectives: To present recent updates in the literature on new potential prognostic factors for DTC.

Methods: We conducted a literature review and analysis of publications regarding DTC prognostic factors or risk stratification published in the last 10 years. 

Results: Several new factors with potential prognostic implications for DTC were noted, including family history, lymph node involvement parameters, positive PET-CT findings, multifocal disease, thyroglobulin level and several molecular markers including BRAF. Increasing age is associated with poorer outcome in DTC; however, recent studies suggest that the cutoff point of 45 years may be contested. Furthermore, several studies have shown contradictory results regarding male gender as a negative prognostic factor, thus questioning its prognostic significance. 

Conclusions: A number of new factors with potential prognostic implications for DTC have emerged and should be addressed. However, their role and possible inclusion in new staging systems has yet to be determined.
