Acromion Morphology of Patients with Rotator Cuff Disease in Standard AP Shoulder Radiograph in Hospital Sultanah Bahiyah and Hospital Kuala Lumpur

Introduction

Rotator cuff pathology is commonly attributed to acromion morphology that is demonstrable in standard AP shoulder radiographs by measuring the critical shoulder angle (CSA), the lateral acromial angle (LAA), and the acromial index (AI). However, these parameters vary among races and countries. Therefore, our study aimed to get the local data on acromion morphology in patients with rotator cuff disease.

Materials and methods

MRI shoulder reports between January 2012 and June 2018 were reviewed. The study group consisted of 47 patients with rotator cuff injury with a partial or complete tear, and a control group of 37 patients with tendinitis or osteoarthritis and intact rotator cuffs. The CSA, LAA, and AI of both groups were measured on the anteroposterior shoulder radiograph. The risk factors for both groups and the acromion morphology were recorded.

Results

The CSA for the rotator cuff tear and the control group was 39.08° and 38.28°, LAA was 72.57 ° and 73.51°, and AI was 0.79 and 0.75. The acromion morphology differed in terms of gender, and only LAA was different among the different ethnic groups. There was a negative correlation between age and CSA, age and AI, LAA and CSA, LAA and AI, but a positive correlation between AI and CSA.

Conclusion

The CSA for rotator cuff tear patients in our population was 39.08°, LAA was 72.57°, and AI was 0.79. The acromion morphology was significantly influenced by age and gender.

The timing of auditory sensory deficits in Norrie disease has implications for therapeutic intervention

Norrie disease is caused by mutation of the NDP gene, presenting as congenital blindness followed by later onset of hearing loss. Protecting patients from hearing loss is critical for maintaining their quality of life. This study aimed to understand the onset of pathology in cochlear structure and function. By investigating patients and juvenile Ndp-mutant mice, we elucidated the sequence of onset of physiological changes (in auditory brainstem responses, distortion product otoacoustic emissions, endocochlear potential, blood-labyrinth barrier integrity) and determined the cellular, histological, and ultrastructural events leading to hearing loss. We found that cochlear vascular pathology occurs earlier than previously reported and precedes sensorineural hearing loss. The work defines a disease mechanism whereby early malformation of the cochlear microvasculature precedes loss of vessel integrity and decline of endocochlear potential, leading to hearing loss and hair cell death while sparing spiral ganglion cells. This provides essential information on events defining the optimal therapeutic window and indicates that early intervention is needed. In an era of advancing gene therapy and small-molecule technologies, this study establishes Ndp-mutant mice as a platform to test such interventions and has important implications for understanding the progression of hearing loss in Norrie disease.

Anxiety and depression in patients with haematological neoplasms in Malaysia

BACKGROUND

It is not uncommon that anxiety and depression occur in patients with cancers, and past researches have shown that the quality of life of patients is negatively affected. This study aims to determine the prevalence of anxiety and depression of patients with haematological cancers in Malaysia and to investigate the possible association of these psychological symptoms with their quality of life.

METHODS

This is a cross-sectional study where patients with haematological cancers attending two major hospitals were recruited. Anxiety and depression symptoms were assessed using the Hospital Anxiety and Depression scale (HADS). Quality of life (QoL) of these patients was measured using the European Organisation for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ C30). An overall summary QoL score in combination with financial difficulty score and global health score were used for analysis.

RESULTS

A total of 319 patients were recruited. Thirty-three percent of patients had anxiety symptoms, 23.5% had depression symptoms. In summary the overall score of QoL is significantly lower in patients with higher scores for depression and anxiety, (p<0.05). Patients who exhibit anxiety symptoms were more frequently female, still undergoing treatment whereas patients who had higher depression scores were older and had acute leukemias or myeloproliferative neoplasms. Patients who have depression are significantly associated with a higher financial difficulty score, p<0.05.

CONCLUSION

The poor quality of life in patients who have anxiety and depression should raise awareness amongst the health professions treating them so that additional support can be provided.

How We Transmit Memories to Other Brains: Constructing Shared Neural Representations Via Communication

Humans are able to mentally construct an episode when listening to another person's recollection, even though they themselves did not experience the events. However, it is unknown how strongly the neural patterns elicited by mental construction resemble those found in the brain of the individual who experienced the original events. Using fMRI and a verbal communication task, we traced how neural patterns associated with viewing specific scenes in a movie are encoded, recalled, and then transferred to a group of naïve listeners. By comparing neural patterns across the 3 conditions, we report, for the first time, that event-specific neural patterns observed in the default mode network are shared across the encoding, recall, and construction of the same real-life episode. This study uncovers the intimate correspondences between memory encoding and event construction, and highlights the essential role our common language plays in the process of transmitting one's memories to other brains.

Quality of life amongst lymphoma survivors in a developing country

PURPOSE

The survival for patients with lymphoma has improved over the past decades with the introduction of novel agents. Quality of life of these survivors is now being studied with focus on minimising the late effects of chemotherapy and improving psychosocial support. This study aims to determine the prevalence of anxiety and depression of lymphoma survivors and to investigate the possible association between these disorders and quality of life.

METHODS

Patients with previous diagnosis of lymphoma who remained in remission were recruited from a major hospital in Malaysia. Quality of life of these patients was measured using European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ C30). Anxiety and depression symptoms were assessed using Hospital Anxiety and Depression scale (HADS).

RESULTS

A total of 156 patients participated in this study. Eighteen percent (18 %) of patients had symptoms of anxiety, and 10 % had symptoms of depression. Patients who had higher depression scores were older, of lower education level and had more than one comorbidity illness. Patients with anxiety were associated with lower overall quality of life (QOL) score, lower emotional and cognitive functioning and complained more of fatigue and insomnia (p < 0.05). Patients who had depression were associated with lower physical functioning and complained more of insomnia (p < 0.05).

CONCLUSION

It is important for the treating physicians to ensure follow-up of lymphoma survivors for any psychological disorders in order early counseling and support can be provided. This may improve patients' quality of life.
