Boo NY, Zuraidah AL, Lim NL, Zulfiqar MA

J Trop Pediatr, 2000 Jun;46(3):172-5.

PMID: 10893920

A case-control study was carried out on 97 consecutive preterm (< 37 weeks) infants to determine predictors associated with failure of nasal continuous positive airway pressure (CPAP) in the treatment of respiratory distress syndrome (RDS). Logistic regression analysis showed that only three risk factors were significantly associated with failed CPAP. These were: moderate or severe RDS (odds ratio: 5.9; 95 per cent confidence interval (CI): 2.2-16.0); septicemia during CPAP therapy (OR: 8.8; 95 per cent: CI 1.5-50.7); and pneumothorax during CPAP therapy (odds ratio: 6.9; 95 per cent: CI 1.1-41.7).

Pericardial rupture after blunt chest trauma is described in the literature. This case report summarises our experience with a 22-year old male patient who suffered blunt chest trauma during a motor vehicle accident. On admission no serious injuries could be detected, but 3 hours later, displacement of the heart to the right hemithorax combined with sudden cardiac failure appeared. Emergency thoracotomy revealed a right-sided rupture of the pericardium with complete herniation of the heart into the right pleural cavity and consequent strangulation by the margins of the pericardial defect.

Vanishing lung syndrome (VLS) is a rare condition characterized by giant emphysematous bullae. It is frequently misdiagnosed as pneumothorax. We describe a case of a 30-year-old male who presented with shortness of breath, reduced effort tolerance, and pleuritic chest pain for three months. He was initially diagnosed with bilateral pneumothorax based on clinical examination and chest radiograph findings. However, further imaging with a high resolution computed tomography (HRCT) of the thorax confirmed bilateral giant emphysematous bullae. Our patient subsequently underwent video-assisted thoracoscopic surgery (VATS) and bullectomy. In this report, we discuss the clinical presentations, radiological features, and the management of VLS. We also highlight the differentiating features of VLS from a pneumothorax.

MyJurnal

Spontaneous pneumothorax and pneumomediastinum is defined as presence of free air or gas in the pleural cav- ity and mediastinal structures respectively. Spontaneous pneumothorax seems to be associated with anatomical abnormalities such as subpleural blebs or bullae, however not for spontaneous pneumomediastinum which may developed without an apparent precipitating cause. Both usually may occur in young healthy adults without serious underlying lung disease. We report a case of spontaneous pneumothorax and pneumomediastinum after a trivial injury. He was initially presented with dyspnea after two weeks of initial trivial trauma. Chest radiograph showed left apical pneumothorax with pneumomediastinum with no evidence of rib fracture. His condition was deemed non-traumatic by surgical colleague, thus admitted to medical ward for observation and eventually discharged well.

We report a case of occult primary spontaneous
pneumothorax in a 30 years-old woman. She
developed symptoms and signs that were suggestive of
pneumothorax. However, chest radiograph failed to
reveal pneumothorax. Therefore, we proceeded with
computed tomography (CT) thorax which revealed
significantly moderate right pneumothorax. The
diagnostic approach and the management of this case
are discussed.

MyJurnal

Acupuncture is a form of complementary medicine that has been practiced in China for thousands of years. Adverse effect of acupuncture is rarely reported in local literature. This is a case of a patient who developed bilateral pneumothorax following an acupuncture session. A 63-year-old lady with no significant medical illness presented with sudden onset of shortness of breath half an hour following acupuncture and massage session by traditional medicine practitioner. On examination, she was tachypnoiec and there was reduced air entry bilaterally on lung auscultation. Urgent portable chest X-ray was done and it showed bilateral pneumothorax. Bilateral chest tubes were inserted. Patient was discharged well following five days of hospitalization. As acupuncture is gaining popularity among Malaysian population, medical practitioners need to increase their awareness and knowledge regarding the adverse effect of such alternative practice.

Vendargon S, Wong PS, Tan KK

Med J Malaysia, 2000 Dec;55(4):520-3.

PMID: 11221169

From 10th September 1998 till 5th June 1999, the Paediatric and Cardiothoracic Surgery Units of Sultanah Aminah Hospital Johor Bahru managed three children with lung collapse secondary to pneumonia. The dominant initial clinical presentation in all three cases was acute abdominal pain. Basal pneumonia was diagnosed in two cases post-operatively after surgical contributory causes were excluded intra-operatively. Thoracotomy, evacuation of infected debris and decortication of the collapsed lung was done in all three cases. In children presenting with acute abdominal pain, basal pneumonia should be considered as a possible contributory cause.

PMID: 8326234

A case of massive pyopneumothorax as a rare sequelae of retropharyngeal abscess following fish bone ingestion is reported. An initial attempt at removal of the fish bone in the oesophagus using the fibroptic oesophagoscope was unsuccessful, causing failure of its removal and the development of this rare and potentially fatal complication. The intercommunication of the retropharyngeal space with other spaces of the neck and thorax that allow this and most other complications to occur is described. Rigid endoscopes are the instrument of choice in retrieving sharp foreign bodies in the oesophagus.

International e-Journal of Science, Medicine & Education, 2015;9(2):37-39.

MyJurnal

Anaphylaxis in the operating room although infrequent can be potentially fatal. The diagnosis of perioperative anaphylaxis is complex due to a multitude of factors. Firstly, patients under anesthesia cannot verbalize their complaints, the anesthetic agents themselves can alter vital parameters (e.g. heart rate and blood pressure) and cutaneous signs in a completely draped patient may be missed. Secondly, the differential diagnosis of intraoperative anaphylaxis is wide. Conditions such as asthma exacerbation, arrhythmia, hemorrhage, angioedema, mastocytosis, acute myocardial infarction, drug overdose, pericardial tamponade, pulmonary edema, pulmonary embolus, sepsis, tension pneumothorax, vasovagal reaction, venous air embolism, laryngospasm, blood transfusion reaction and malignant hyperthermia need to be considered. Thirdly, the diagnostic workup is challenging due to the multiple medications administered and other exposures encountered such as latex and chlorhexidene. However, through a timely allergy consultation and a systematic approach, identification of the culprit agent and safe alternatives can be established to prevent future occurrences as illustrated in the case below.

Pneumothorax is the presence of air in the pleural cavity. It can be classified into spontaneous, traumatic or iatrogenic. The majority of pneumothorax cases are spontaneous, which can be further classified into primary spontaneous pneumothorax (PSP) or secondary spontaneous pneumothorax (SSP), defined by the absence or presence of obvious underlying lung disease respectively. The treatment of spontaneous pneumothorax includes simple aspiration, intercostal tube drainage or surgical intervention. When intercostal tube drainage is used, it is usually attached to an underwater-seal system. Mobile chest drains, such as the Heimlich valve, replace the underwater-seal and allow outpatient management of spontaneous pneumothoraces. The Heimlich valve however, is costly and not readily available in many local hospitals. Cheaper and easily obtainable alternatives which are also safe are being sought. This is a case report describing the use of the urine bag in the management of a patient with spontaneous pneumothrax.

Fulltext Effect of Lung Recruitment and Titrated Positive End-Expiratory Pressure (PEEP) vs Low PEEP on Mortality in Patients With Acute Respiratory Distress Syndrome: A Randomized Clinical Trial

Writing Group for the Alveolar Recruitment for Acute Respiratory Distress Syndrome Trial (ART) Investigators, Cavalcanti AB, Suzumura ÉA, Laranjeira LN, Paisani DM, Damiani LP, et al.

JAMA, 2017 10 10;318(14):1335-1345.

PMID: 28973363 DOI: 10.1001/jama.2017.14171

Importance: The effects of recruitment maneuvers and positive end-expiratory pressure (PEEP) titration on clinical outcomes in patients with acute respiratory distress syndrome (ARDS) remain uncertain.

Objective: To determine if lung recruitment associated with PEEP titration according to the best respiratory-system compliance decreases 28-day mortality of patients with moderate to severe ARDS compared with a conventional low-PEEP strategy.

Design, Setting, and Participants: Multicenter, randomized trial conducted at 120 intensive care units (ICUs) from 9 countries from November 17, 2011, through April 25, 2017, enrolling adults with moderate to severe ARDS.

Interventions: An experimental strategy with a lung recruitment maneuver and PEEP titration according to the best respiratory-system compliance (n = 501; experimental group) or a control strategy of low PEEP (n = 509). All patients received volume-assist control mode until weaning.

Main Outcomes and Measures: The primary outcome was all-cause mortality until 28 days. Secondary outcomes were length of ICU and hospital stay; ventilator-free days through day 28; pneumothorax requiring drainage within 7 days; barotrauma within 7 days; and ICU, in-hospital, and 6-month mortality.

Results: A total of 1010 patients (37.5% female; mean [SD] age, 50.9 [17.4] years) were enrolled and followed up. At 28 days, 277 of 501 patients (55.3%) in the experimental group and 251 of 509 patients (49.3%) in the control group had died (hazard ratio [HR], 1.20; 95% CI, 1.01 to 1.42; P = .041). Compared with the control group, the experimental group strategy increased 6-month mortality (65.3% vs 59.9%; HR, 1.18; 95% CI, 1.01 to 1.38; P = .04), decreased the number of mean ventilator-free days (5.3 vs 6.4; difference, -1.1; 95% CI, -2.1 to -0.1; P = .03), increased the risk of pneumothorax requiring drainage (3.2% vs 1.2%; difference, 2.0%; 95% CI, 0.0% to 4.0%; P = .03), and the risk of barotrauma (5.6% vs 1.6%; difference, 4.0%; 95% CI, 1.5% to 6.5%; P = .001). There were no significant differences in the length of ICU stay, length of hospital stay, ICU mortality, and in-hospital mortality.

Conclusions and Relevance: In patients with moderate to severe ARDS, a strategy with lung recruitment and titrated PEEP compared with low PEEP increased 28-day all-cause mortality. These findings do not support the routine use of lung recruitment maneuver and PEEP titration in these patients.

We report a case of a young man who presented with a left-sided pneumothorax after suffering an accidental penetrating injury by a sewing needle to the anterior chest wall. Chest radiograph and the computed tomography of the thorax revealed that the needle was in the pleural cavity and there was an associated pneumothorax. An attempt at retrieval by direct incision failed. The sewing needle was successfully retrieved by a medical pleuroscopy. The patient recovered without any consequences and was discharged home after 24 hours of observation.

Perinatal characteristics and outcome of neonates born in thick meconium-stained liquor

Ida, S.B.O., Teh, K.H., Quah, B.S.

Malaysian Journal of Paediatrics and Child Health, 2000;12(1):16-21.

MyJurnal

Meconium aspiration syndrome (MAS) frequently occurs in neonates born in thick meconium-stained liquor (TMSL). It continues to be a significant cause of neonatal morbidity and mortality despite aggressive approaches to intervention. This study aims to identify the perinatal characteristics of deliveries with TMSL associated with the development of MAS and to describe the outcome of those babies who developed MAS.
All newborns with TMSL born in Hospital Alor Setar, Kedah from 1 October 1998 to 30 April 1999 were prospectively studied. In the hospital, all newborns with TMSL were routinely admitted to the Special Care Nursery for observation. Relevant data regarding pregnancy, delivery, resuscitation and outcome of newborns with and without MAS were collected and analysed. The incidence of TMSL among hospital deliveries was 2.2% (95% C.I. 1.8-2.5%). Thirty-six percent (95% C.I. 28.4-44.7%) of newborns with TMSL developed MAS. Significant risk factors associated with the development of MAS were non-Malay mothers (p=0.04, OR=3.32), resuscitation by paediatric medical officers (p=0.02, OR=2.84) and direct tracheal suction during resuscitation (p=0.02, OR=2.61). The presence of non-Malay mothers or resuscitation by paediatric medical officers or direct tracheal suction during resuscitation gave a sensitivity of 88.2%, specificity of 36.7%, a positive predictive value of 44.1% and a negative predictive value of 84.6% for the development of MAS. Asphyxia, pneumothorax and persistent pulmonary hyper-tension occurred in 25.5%, 7.8% and 5.9% of the babies with MAS respectively. Mechanical ventilation was required in 51% and the mortality rate was 3.9%. In conclusion, the incidence of TMSL and MAS and the mortality rate of neonates with MAS were comparable with that in developed countries. The presence of any one of the significant risk factors had high sensitivity but low specificity for the development of MAS. Newborns were unlikely to develop MAS if all these risk factors were absent.
