Background: The cytology and the support of clinical symptoms, biochemistry for diagnosis of the cases of effusions are very important. Objectives: - To describe some of clinical symptoms and biochemistry of effusions. - To compare the results between cytology and biochemistry by the causes of pleural, peritoneal fluids. Material & Method: A cross-sectional study to describe all of 47 patients with pleural, peritoneal effusions examinated by cytology in the Hospital of Hue University of Medicine and Pharmacy from April 2013 to January 2014. Results: In 47 cases with effusions, pleural effusion accounting for 55.32%, following peritoneal effusions 29.79% and 14.89% with both of them. The most common symptoms in patients with pleural effusions were diminished or absent tactile fremitus, dull percussion, diminished or absent breath sounds (100%), in patients with peritoneal effusions was ascites (95.24%). 100% cases with pleural effusions, 50% cases with peritoneal effusions and 80% cases with pleural and peritoneal effusions were exudates. The percentage of malignant cells in patients with pleural effusions was 26.92%, in peritoneal effusions was 28.57%, in pleural and peritoneal effusions was 42.86%. The percentage of detecting the malignant cells in patients with suspected cancer in the first test was 57.14%, in the second was 9.53% and 33.33% undetectable. Most of cases which had malignant cells and inflammatory were exudates, all of the cases which had a few cells were transudates. Besides, 7.5% cases which had high neutrophil leukocytes were transudates. Conclusion: Cytology should be carry out adding to the clinical examinations and biochemistry tests to have an exact diagnosis, especially for the malignant ones. For the case with suspected cancer, we should repeat cytology test one more time to increase the ability to detect malignant cells.

Survival Case

A 20-year-old woman presented with abdominal pain and shortness of breath. She was in obstructive shock with absent breath sounds on the left haemithorax. Chest X-ray showed a large radiolucent shadow with absent lung markings and mediastinal shift to the right side with concerns for tension pneumothorax. Though tube thoracostomy was done on the left side of the chest, column movement was absent. To confirm the diagnosis CT with contrast was done that revealed a huge left side diaphragmatic defect with abdominal contents in the thorax and mediastinal structures are shifted to left. She underwent emergency laparotomy and postoperative period was uneventful.

AbstractMonitoring pathological mechano-acoustic signals emanating from the lungs is critical for timely and cost-effective healthcare delivery. Adventitious lung sounds including crackles, wheezes, rhonchi, bronchial breath sounds, stridor or pleural rub and abnormal breathing patterns function as essential clinical biomarkers for the early identification, accurate diagnosis and monitoring of pulmonary disorders. Here, we present a wearable sensor module comprising of a hermetically encapsulated, high precision accelerometer contact microphone (ACM) which enables both episodic and longitudinal assessment of lung sounds, breathing patterns and respiratory rates using a single integrated sensor. This enhanced ACM sensor leverages a nano-gap transduction mechanism to achieve high sensitivity to weak high frequency vibrations occurring on the surface of the skin due to underlying lung pathologies. The performance of the ACM sensor was compared to recordings from a state-of-art digital stethoscope, and the efficacy of the developed system is demonstrated by conducting an exploratory research study aimed at recording pathological mechano-acoustic signals from hospitalized patients with a chronic obstructive pulmonary disease (COPD) exacerbation, pneumonia, and acute decompensated heart failure. This unobtrusive wearable system can enable both episodic and longitudinal evaluation of lung sounds that allow for the early detection and/or ongoing monitoring of pulmonary disease.

To the Editor.— The frequent determination of vital signs, such as heart rate and bilateral breath sounds, is a mainstay in the care of critically ill infants. Unfortunately, the routine determination of such vital signs involves the manipulation and disturbance of the infant, unnecessary risk of exposure to cold, increased risk of apnea, and infection.1,2 In addition, the frequent disruption of the infant's sleep pattern may take an unaccountable physiologic and psychologic toll. To deal with this common and challenging problem we have devised a simple and inexpensive monitoring device, using readily available supplies, which facilitates the continuous or intermittent evaluation of heart rate and bilateral breath sounds.

Pleural Involvement

The presence of fluid in the pleural space can be seen in a variety of disorders. Presenting symptoms include dyspnea, pleuritic chest pain, and ipsilateral shoulder pain if pleural involvement occurs at the central portion of the diaphragm. Physical examination findings include chest asymmetry, diminished breath sounds, dullness to percussion, and decreased tactile fremitus. In an upright patient, the radiographic appearance of pleural fluid includes blunting of the costophrenic angle, straightening or a more lateral peak of the hemidiaphragm contour, simulation of an elevated hemidiaphragm, or a distance of greater than 2 cm between the gastric air bubble and the lung.

Arthroscopic Shoulder Surgery

BackgroundThe interscalene brachial plexus block has been used effectively for intraoperative and postoperative analgesia in patients undergoing shoulder surgery, but it is associated with high rates of diaphragmatic dysfunction. Performing the block more distally, at the level of the superior trunk, may reduce the incidence of phrenic nerve palsy. We hypothesized that superior trunk block would result in diaphragmatic paralysis rate of less than 20%.Methods30 patients undergoing arthroscopic shoulder surgery received superior trunk block under ultrasound guidance. Measurements of diaphragm excursion were determined with ultrasound prior to the block, 15 min after the block, and postoperatively in phase II of postanesthesia care unit, in conjunction with clinical parameters of respiratory function.Results10 patients (33.3%, 95% CI 17.3% to 52.8%) developed complete hemidiaphragmatic paralysis at the postoperative assessment. An additional eight patients (26.7%) developed paresis without paralysis. Of the 18 patients with diaphragm effects, seven (38.9%) reported dyspnea. 83.3% of patients with abnormal diaphragm motion (56.7% of the total sample) had audibly reduced breath sounds on auscultation. Oxygen saturation measurements did not correlate with diaphragm effect and were not significantly reduced by the postoperative assessment.ConclusionAlthough injection of local anesthetic at the superior trunk level is associated with less diaphragmatic paralysis compared with traditional interscalene block, a significant portion of patients will continue to have ultrasonographic and clinical evidence of diaphragmatic weakness or paralysis.
