    Recommendation of oxygen therapy must include clear indication and benefits of its use, appropriate prescription, vigilant monitoring and appropriate methods of delivery. Home oxygen therapy is expensive, inconvenient and cumbersome; it should be recommended only if benefits outweigh the disadvantages and adverse effects of oxygen. GPs play an important supportive and supervisory role in the use of long-term oxygen therapy (LTOT) to improve mortality of patients with chronic hypoxaemia. Prescription of short burst oxygen therapy (SBOT) for palliation of breathlessness is without clear evidence of its efficacy. GPs can prescribe SBOT when other secondary causes of breathlessness are excluded or treated, when breathlessness is not relieved by other treatments and if an improvement can be documented in patients.

    Summary: Home oxygen therapy programme is new in Malaysia. This programme enables children with respiratory insufficiency to be discharged home early.
    Materials and Methods: Long term oxygen therapy was initiated using an oxygen concentrator in patients who i) remained hypoxic while breathing room air, ii) experienced desaturations of more than 20% during sleep as seen in patients with severe laryngomalacia and obstructive sleep apnoea syndrome and iii) had pulmonary hypertension with or without polycythemia. The median with first and third quartile values are presented for the quantitative variables.
    Results: A total of 71 patients mainly children with bronchopulmonary dysplasia (BPD) (32) and bronchiolitis obliterans (12) were discharged home on this programme. The median age at which home oxygen was initiated in children with BPD was 5.0 (Q1:2 Q3:8) months. The median total duration of oxygen requirement for BPD was 8.0 (Q1:5, Q3:12) months. The median duration of home oxygen dependency was 3.5 (Q1:3, Q3:6) months. However children with bronchiolitis obliterans required longer duration of oxygen therapy compared to children with BPD i.e. median duration of 28 months (Q1:14.5 Q3:66). In other respiratory conditions the mean duration of supplemental oxygen varies some of which may be life long.
    Conclusions: This paper has shown the importance of home oxygen program in children with respiratory disorders. It has significantly shortened hospital stay and thus saves hospital costs and prevents prolonged separation from the family.

    BACKGROUND AND OBJECTIVES: Lower concentrations of oxygen (O2) (≤30%) are recommended for preterm resuscitation to avoid oxidative injury and cerebral ischemia. Effects on long-term outcomes are uncertain. We aimed to determine the effects of using room air (RA) or 100% O2 on the combined risk of death and disability at 2 years in infants <32 weeks' gestation.

    METHODS: A randomized, unmasked study designed to determine major disability and death at 2 years in infants <32 weeks' gestation after delivery room resuscitation was initiated with either RA or 100% O2 and which were adjusted to target pulse oximetry of 65% to 95% at 5 minutes and 85% to 95% until NICU admission.

    RESULTS: Of 6291 eligible patients, 292 were recruited and 287 (mean gestation: 28.9 weeks) were included in the analysis (RA: n = 144; 100% O2: n = 143). Recruitment ceased in June 2014, per the recommendations of the Data and Safety Monitoring Committee owing to loss of equipoise for the use of 100% O2. In non-prespecified analyses, infants <28 weeks who received RA resuscitation had higher hospital mortality (RA: 10 of 46 [22%]; than those given 100% O2: 3 of 54 [6%]; risk ratio: 3.9 [95% confidence interval: 1.1-13.4]; P = .01). Respiratory failure was the most common cause of death (n = 13).

    CONCLUSIONS: Using RA to initiate resuscitation was associated with an increased risk of death in infants <28 weeks' gestation. This study was not a prespecified analysis, and it was underpowered to address this post hoc hypothesis reliably. Additional data are needed.

    Dopamine (DA) is one of the key neurotransmitters in the striatum, which is functionally important for a variety of cognitive and motor behaviours. It is known that the striatum is vulnerable to damage from traumatic brain injury (TBI). However, a therapeutic approach has not yet been established to treat TBI. Hence, the present work aimed to evaluate the ability of Normobaric hyperoxia treatment (NBOT) to recover dopaminergic neurons following a fluid percussion injury (FPI) as a TBI experimental animal model. To examine this, mice were divided into four groups: (i) Control, (ii) Sham, (iii) FPI and (iv) FPI+NBOT. Mice were anesthetized and surgically prepared for FPI in the striatum and immediate exposure to NBOT at various time points (3, 6, 12 and 24 h). Dopamine levels were then estimated post injury by utilizing a commercially available ELISA method specific to DA. We found that DA levels were significantly reduced at 3 h, but there was no reduction at 6, 12 and 24 h in FPI groups when compared to the control and sham groups. Subjects receiving NBOT showed consistent increased DA levels at each time point when compared with Sham and FPI groups. These results suggest that FPI may alter DA levels at the early post-TBI stages but not in later stages. While DA levels increased in 6, 12 and 24 h in the FPI groups, NBOT could be used to accelerate the prevention of early dopaminergic neuronal damage following FPI injury and improve DA levels consistently.

    In Study A, the incidence of arterial oxygen desaturation was studied using pulse oximetry (SaO2) in 100 sedated and 100 nonsedated patients breathing room air who underwent diagnostic upper gastrointestinal endoscopy. Hypoxia (SaO2 92% or less of at least 15 s duration) occurred in 17% and 6% of sedated patients and nonsedated patients, respectively (p < 0.03). Mild desaturation (SaO2 94% or less and less than 15 s duration) occurred in 47% of sedated patients compared with 12% of nonsedated patients (p < 0.001). In Study B, the effects of supplementary oxygen therapy and the effects of different pre-oxygenation times on arterial oxygen saturation (SaO2) in sedated patients were studied using pulse oximetry. One hundred and twenty patients who underwent diagnostic upper gastrointestinal endoscopy with intravenous sedation were studied. Patients were randomly allocated to one of four groups: Group A (n = 30) received no supplementary oxygen while Groups B-D received supplementary oxygen at 4 1 x min(-1) via nasal cannulae. The pre-oxygenation time in Group B (n = 30) was zero minutes, Group C (n = 30) was 2 min and Group D (n = 30) was 5 min before sedation and introduction of the endoscope. Hypoxia occurred in seven of the 30 patients in Group A and none in groups B, C and D (p < 0.001). We conclude that desaturation and hypoxia is common in patients undergoing upper gastrointestinal endoscopy with and without sedation. Sedation significantly increases the incidence of desaturation and hypoxia. Supplementary nasal oxygen at 4 1 x min(-1) in sedated patients abolishes desaturation and hypoxia. Pre-oxygenation confers no additional benefit.

    One hundred and thirteen consecutive infants with a very low birthweight of less than 1500 g were followed prospectively for 6 months to determine the incidence of retinopathy of prematurity (ROP) and associated risk factors. Of this group, 36 (31.9%) infants developed ROP (13 infants had stage 1 ROP, nine had stage 2, six had stage 3, six had stage 4, and two had cicatricial stage ROP). Stepwise logistic regression analysis of various potential risk factors (birthweight, gestation, duration of oxygen therapy, duration of ventilation, highest documented PaO2 and exchange transfusion) showed that only two risk factors were significantly associated with the development of ROP. These risk factors were: the duration of oxygen therapy (p = 0.0005) and exchange transfusion during the neonatal period (odds ratio 5.754, 95% confidence interval 1.002 to 32.997, p = 0.049). The equation of the regression model is: log (odds of developing ROP) = -0.8395 + 0.1447 (OXY)- 0.8750 (ET), where OXY is the duration of oxygen therapy in days, ET = -1 when there was a history of exchange transfusion, and ET = 1 when there was no history of exchange transfusion.

    Acupuncture is an ancient complementary medicine which is currently used worldwide. Many serious adverse events have been reported which include a spectrum of mild-to-fatal complications. However, the level of awareness with regard to complications is still low both to physicians and patients. We report a 63-year-old who presented with acute shortness of breath 2 hours after having had acupuncture. On examination, there was absent breath sound heard on the left lung and slightly reduced breath sound on the right lung. She had type 1 respiratory failure. Urgent chest radiograph confirmed bilateral pneumothorax which was more severe on the left with tension pneumothorax and mediastinal shift. Chest tubes were inserted bilaterally after failed needle aspiration attempts. Subsequently, the pneumothoraces resolved, and she was discharged well. The bilateral pneumothoraces caused by acupuncture were curable but could have been potentially fatal if diagnosis was delayed. This case report adds to the limited current literature on the complications of acupuncture leading to bilateral pneumothoraces.

    OBJECTIVE: To determine rates of death or neurodevelopmental impairment (NDI) at 2 years corrected age (primary outcome) in children <32 weeks' gestation randomized to initial resuscitation with a fraction of inspired oxygen (FiO2) value of 0.21 or 1.0.

    STUDY DESIGN: Blinded assessments were conducted at 2-3 years corrected age with the Bayley Scales of Infant and Toddler Development, Third Edition or the Ages and Stages Questionnaire by intention to treat.

    RESULTS: Of the 290 children enrolled, 40 could not be contacted and 10 failed to attend appointments. Among the 240 children for whom outcomes at age 2 years were available, 1 child had a lethal congenital anomaly, 1 child had consent for follow-up withdrawn, and 23 children died. The primary outcome, which was available in 238 (82%) of those randomized, occurred in 47 of the 117 (40%) children assigned to initial FiO2 0.21 and in 38 of the 121 (31%) assigned to initial FiO2 1.0 (OR, 1.47; 95% CI, 0.86-2.5; P = .16). No difference in NDI was found in 215 survivors randomized to FiO2 0.21 vs 1.0 (OR, 1.26; 95% CI, 0.70-2.28; P = .11). In post hoc exploratory analyses in the whole cohort, children with a 5-minute blood oxygen saturation (SpO2) <80% were more likely to die or to have NDI (OR, 1.85; 95% CI, 1.07-3.2; P = .03).

    CONCLUSIONS: Initial resuscitation of infants <32 weeks' gestation with initial FiO2 0.21 had no significant effect on death or NDI compared with initial FiO2 1.0. Further evaluation of optimum initial FiO2, including SpO2 targeting, in a large randomized controlled trial is needed.

    Training at high altitude for prolonged periods can cause low oxygen tension which can developed complication of hypoxia. Hypoxia is a cascade activity from a level of down regulation and function of cell’s nucleus. Early detection of biomarker and physiological changes are important in prevent the hypoxia at high altitude. Hyperbaric medicine is a new treatment that were used an oxygen therapy to treat hypoxic and inflammatory driven conditions which patients are treated with 100% oxygen at pressure greater than atmospheric pressure. The review discusses physiological changes associated with hypoxia, the response of biomarker hypoxia changes in high altitude and the role of hyperbaric oxygen therapy can play as part of the treatment for pilots and athletes training at high altitudes that suffering from disease with underlying hypoxia.

    Sabah in Malaysian Borneo is among the Malaysian states which reported a high number of detected COVID-19 cases during the current pandemic. Due to geographical challenges and limited resources, clinicians developed novel strategies for managing patients. The use of a dual oxygen concentrator system for mechanical ventilation is one of the innovations developed by retrieval team members from the Emergency Department (ED) of the Sabah Women and Children's Hospital. Due to conditions requiring isolation of patients suspected of or positive for COVID-19, high-risk patients were treated in an ED extension area that lacked central wall oxygen. Direct access to oxygen tanks became the only viable option, but ensuring a continuous supply was laborious. The novel setup described within this paper has been used on intubated patients in the ED extension area with moderate to high ventilator settings successfully. This simple setup, designed to meet the limited resources within a pandemic environment, needed only a turbine-driven ventilator, two oxygen concentrators, a 3-way connector, and three oxygen tubing. The application of this setup could potentially save more critically ill patients who are being managed in resource-limited conditions such as in smaller district hospitals or out in the field.

    Acute exacerbations of chronic obstructive pulmonary disease (COPD) are important events in COPD patients and place a large burden on healthcare resources. COPD patients with frequent exacerbations have accelerated decline in lung function, poorer health status and are at higher risk of mortality. The mainstay of treatment includes increasing short acting bronchodilator therapy and systemic glucocorticosteroids with or without antibiotics. Non invasive ventilation is indicated in those with respiratory failure with acidosis or hypercapnia. Preventive strategies to reduce exacerbations include smoking cessation, immunisation against influenza and S. pneumonia, chronic maintenance inhaled pharmacotherapy, pulmonary rehabilitation and self management education.

    Six children who survived severe acute bronchiolitis in infancy and early childhood continued to have persistent symptoms of breathlessness, cough and wheeze resistant to bronchodilator therapy. Hyperinflation of the chest, widespread crepitations and rhonchi were persistent clinical features. Failure to thrive was a problem in most. At presentation clinical measles was diagnosed in one child and adenovirus titres were raised in another; the aetiological agents in the others were not known. Lung biopsy from the child with measles showed features of severe bronchiolitis. The clinical and radiological features and course of the illness were consistent with those of bronchiolitis obliterans. Although illness was prolonged the long term prognosis was satisfactory with the majority of children showing improved chest signs, growth and general health after four to eight years of follow up.

    BACKGROUND: De novo pulmonary embolism (DNPE) is a term used when pulmonary embolism (PE) occur in the absence of deep vein thrombosis (DVT). Most DNPE cases occur in a patient who had a recent injury to the chest.

    CASE PRESENTATION: However, here we report a case of DNPE with a slightly different presentation where there is no preceding trauma and has symptoms that mimic severe pneumonia. He presented with high fever, dyspnoea and pleuritic chest pain. Despite on 10 L of oxygen supplementation via high flow mask and already given bolus intravenous antibiotic, the patient still tachypnoeic and was persistently in type I respiratory failure. His chest X-ray showed consolidative changes. Upon further investigation revealed no evidence of DVT on Doppler ultrasound and normal D-dimer level. Due to the high index of suspicion by the attending physician, PE was suspected and later confirmed with computed tomography pulmonary angiography scan. He was successfully treated with anticoagulation therapy. The objective of this case report is to share the difficult experience of diagnosing PE when the presentation highly atypical and mimics severe pneumonia.

    CONCLUSION: And with such a masquerading presentation, one can easily miss the diagnosis. To the best of our knowledge, there are very few similar cases reported.

    This study aims to determine the prevalence of and risk factors associated with retinopathy of prematurity (ROP) in very low birth weight (VLBW) infants. All premature VLBW infants, admitted into the neonatal intensive care unit of the University Hospital Kuala Lumpur, were screened from 4 weeks of life. Perinatal and neonatal data were retrieved from the infants' medical notes. Between August 1994 and July 1996, 100 infants had their eyes examined serially. Of the 15 (15%) infants with ROP, all were less than 31 weeks gestation, and only 1 infant had birth weight above 1250 g. Five (5%) infants had severe ROP; 4 infants underwent cryotherapy for stage 3 threshold disease. Infants with ROP, as compared to infants without ROP, had lower birth weight [mean (SEM) 993 (50) g versus 1205 (22) g, P < 0.001], lower gestational age [mean (SEM) 28.0 (0.4) weeks versus 30.1 (0.2) weeks, P < 0.001], higher rates of patent ductus arteriosus and chronic lung disease, greater number of radiographic examinations and episodes of late-onset suspected/confirmed sepsis, and required longer duration of supplemental oxygen, ventilation, xanthine, antibiotics and intralipid use, but were slower to establish full enteral feeds. On multivariate logistic regression analysis, birth weight < or = 1000 g [OR 2.38, 95% CI 1.25, 4.55, P = 0.009] and gestational age < or = 28 weeks [OR 2.86, 95% CI 1.47, 5.56, P = 0.002] were significant predictors of increased risk of this disease. In conclusion, ROP is strongly associated with smaller, more immature and sicker neonates. Prevention of prematurity would help reduce the incidence of this disease.
