Currently, there is no cure for pediatric diffuse brain stem (BS) tumors. Radiotherapy, including proton therapy, is an important component of combination treatment for this cancer, especially in children with a complicated medical history. The article addresses the issues of therapy for pediatric BS tumors and reports the use of proton re-irradiation in a 9-year-old boy with unverified diffuse BS tumor. Proton re-irradiation is an effective treatment option that can sustain and improve the quality of life and prolong survival in children with diffuse BS tumors.

Abstract Background:Interstitial pneumonia (IP) is a disease with a poor prognosis. In addition, IP patients are more likely to develop lung cancer. Since IP patients frequently develop toxicities during cancer treatment, minimally invasive cancer treatment is warranted for such patients to maintain their quality of life. This study retrospectively investigated the efficacy and safety of proton therapy (PT) for non-small cell lung cancer (NSCLC) in patients with IP.Methods:Twenty-nine NSCLC patients with IP were treated with PT between September 2013 and December 2019. The patients had stage IA to IIIB primary NSCLC. Ten of the 29 patients exhibited the usual interstitial pneumonia pattern. The prescribed dose was 66-74 Grays (relative biological effectiveness) in 10-37 fractions.Results:The median follow-up period was 17.4 months (interquartile range (IQR), 9.5–32.7). The median patient age was 77 years (IQR, 71–81). The median planning target volume was 112.0 ml (IQR, 56.1–246.3). The 2-year local control, progression-free survival, and overall survival rates were 77% (95% confidence interval: 34 to 94), 31% (13–50), and 50% (26–70), respectively. According to the Common Terminology Criteria for Adverse Events (version 4.0), grade 3 acute radiation pneumonitis (RP) was observed in 1 patient. Two patients developed grade 3 late RP, but no other patients experienced serious toxicities. The patients’ quality of life (European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-LC13 and SF-36) scores had not changed after 3 months.Conclusions:PT may safely control NSCLC without adversely affecting the daily lives of IP patients.

Inherited retinal diseases (IRDs) are a leading cause of blindness. To date, 260 disease-causing genes have been identified, but there is currently a lack of available and effective treatment options. Cone photoreceptors are responsible for daylight vision but are highly susceptible to disease progression, the loss of cone-mediated vision having the highest impact on the quality of life of IRD patients. Cone degeneration can occur either directly via mutations in cone-specific genes (primary cone death), or indirectly via the primary degeneration of rods followed by subsequent degeneration of cones (secondary cone death). How cones degenerate as a result of pathological mutations remains unclear, hindering the development of effective therapies for IRDs. This review aims to highlight similarities and differences between primary and secondary cone cell death in inherited retinal diseases in order to better define cone death mechanisms and further identify potential treatment options.

Introduction: Liver Cancer is aggressive cancer and patients are mostly screened and diagnosed when they become symptomatic at advanced. Disease severity, depression, fatigue, joint pain, and poor appetite have been reported as strong determinants of quality of life (QoL) among liver cancer patients. Aims: The objective of the study was to assess the quality of life and depression among liver cancer patients in Pakistan. Study Design:  A descriptive cross-sectional study design was used. Place and Duration of Study: The study was conducted in healthcare facilities of Islamabad and Rawalpindi, Pakistan between June 2020-December 2020. Methodology: Two pre-validated questionnaires i.e. EORTC QLQ-C30 and HADS were self-administered to a sample of 100 liver cancer patients selected using a convenience sampling technique for measuring QoL and depression, respectively. After data collection, data was cleaned, coded, and entered in SPSS. Results: The results highlighted that the lowest scores observed in the domain of symptom scale were: Nausea and Vomiting (23.72, ± 28.238), Dyspnea (25.27, ± 26.90), Constipation (26.03, ± 34.75) followed by Diarrhea (22.63, ± 28.42), whereas highest scores in the symptom scale were observed in the domain of fatigue (37.69, ± 20.06), pain (40.37, ± 18.44), insomnia (41.65, ± 32.37) and financial difficulties (60.33, ± 33.830). On the other hand, highest score on the functional scale was observed for physical functioning (64, ± 21.76) and the lowest score was observed in social functioning (53.19, ± 20.66). Conclusion: The present study concluded that liver cancer had a negative impact on risk factors/past medical history, co-morbidities, and poor socio-economic of life across all domains along with moderate depression in liver cancer patients. Illiteracy, advanced liver cancer stage, risk factors/past medical history, co-morbidities and poor socio-economic status negatively affected functional and symptom scale. Appropriate health educational and psychological interventional programs targeting patients should be initiated to improve awareness and reduce depression among liver cancer patients.

Abstract To investigate optimal treatment planning using proton beams for non-squamous cell carcinoma of the head and neck (NSCHN), the dose distributions of plans involving pencil beam scanning (PBS) with or without a patient-specific aperture system (PSAS), passive-scattering proton therapy (PSPT) and X-ray intensity-modulated radiotherapy (IMRT) were compared. As clinical results, toxicities of PBS with PSAS, including changes in quality of life, were reported. Between April 2014 and August 2016, a total of 30 patients were treated using PBS with PSAS. In 20 patients selected at random, the dose distributions of PBS with or without the PSAS, PSPT and IMRT plans were compared. Neutron exposure by proton therapy was calculated using a Monte Carlo simulation. Toxicities were scored according to CTCAE ver. 4.0. Patients completed EORTC quality of life survey forms (QLQ-C30 and QLQ-HN35) before and 0–12 months after proton therapy. The 95% conformity number of PBS with the PSAS plan was the best, and significant differences were detected among the four plans (P < 0.05, Bonferroni tests). Neutron generation by PSAS was ~1.1-fold higher, but was within an acceptable level. No grade 3 or higher acute dermatitis was observed. Pain, appetite loss and increased weight loss were more likely at the end of treatment, but recovered by the 3 month follow-up and returned to the pretreatment level at the 12 month follow-up. PBS with PSAS reduced the penumbra and improved dose conformity in the planning target volume. PBS with PSAS was tolerated well for NSCHN.

Background: Lateral epicondylitis is one of the most common causes of elbow pain. It is generally observed in people between the ages of 40 and 50 years, and the dominant extremity is more frequently affected. Various noninvasive methods are frequently used; however, studies investigating the effectiveness of the orthoses are limited and with controversial outcomes. Objective: To investigate the effectiveness of a hand-wrist resting orthosis and an epicondylitis bandage in lateral epicondylitis. Study design: Randomized controlled trial. Methods: In total, 82 patients diagnosed with unilateral lateral epicondylitis were enrolled into the study. Hand-wrist resting orthosis was applied to 45 patients and epicondylitis bandage was applied to 41 patients. Patients were evaluated before treatment and at 6 weeks after treatment with a Visual Analogue Scale; Disabilities of the Arm, Shoulder, and Hand questionnaire; the Short Form 36; and a determination of hand grasping force. Results: Both groups were similar in terms of age, body mass index, gender, frequency of lateral epicondylitis on the dominant side, dominant extremity, and duration of complaints ( p > 0.05). A statistically significant recovery was detected in both groups between the pre-therapy values and the values at the sixth week in terms of Visual Analogue Scale scores; Disabilities of the Arm, Shoulder, and Hand questionnarie scores; hand grasping forces; and the Short Form 36 mental and physical component scores ( p < 0.05). However, there were no significant differences detected between the two therapy methods before the therapy and at the sixth week of treatment in all parameter values ( p > 0.05). Conclusion: Our results suggest that both epicondylitis bandage and hand-wrist resting orthosis are effective treatment options for lateral epicondylitis–induced pain, functional status, muscle strength, and quality of life. Furthermore, neither treatment option was superior to the other. Large, randomized studies are necessary for more clear statements. Clinical relevance Epicondylitis bandage and hand-wrist resting orthosis are equally effective treatment options for lateral epicondylitis–induced pain, functional status, muscle strength, and quality of life.
