Laryngeal fracture is a rare condition with potential life-long implications related to airway patency, voice quality, and swallowing. Rarity of the condition leads to lack of consensus on the most suitable way to manage this injury. The mode of injury can be prevented by strict legislation on the roads. We report a case of a 28-year-old Indian male who sustained a comminuted displaced fracture of the thyroid cartilage with disruption of anterior commissure due to blunt trauma caused by the metallic side rod of a ladder projecting from the rear of a vehicle in front of the bike on which he was riding...

The authors report a case of a 30-year-old nulliparous woman with a prior medical history of asthma who developed intrapartum pneumomediastinum with surgical emphysema during the second stage of labour. She was managed conservatively with supportive care and there was complete resolution of symptoms within 4 days. Clinical and radiological findings were consistent with Hamman's syndrome (spontaneous pneumomediastinum). This case reiterates the possibility of childhood asthma or a family history of asthma as being an associated risk factor for Hamman's syndrome and reminds us of the need to distinguish such clinical findings from more important and potentially life-threatening conditions such as oesophageal rupture, pulmonary embolism and aortic dissection that can present with similar findings...

Pneumorrhachis is a rare phenomenon which may be caused by trauma, intracraneal infection, pneumomediastinum or iatrogenic factors. Presence of air in the spinal canal is reported in most cases. In this article, we report a case with PR in the spinal canal without any neurological deficit, which developed secondary to subcutaneous emphysema.

Objective Jet ventilation has been used for >30 years as an anesthetic modality for laryngotracheal surgery. Concerns exist over increased risk with elevated body mass index (BMI). We reviewed our experience using jet ventilation for laryngotracheal stenosis to assess for complication rates with substratification by BMI. Study Design Case series with chart review. Setting Tertiary care center. Subjects and Methods A total of 126 procedures with jet ventilation were identified from October 2006 to December 2014...

High minute ventilation is required to lower intracranial pressures in patients with intracranial bleed. Respiratory acidemia consequent to ventilatory difficulty is dangerous in such patients as it further raises intracranial tension. We describe such a case. A 24-year-old man had to be intubated and mechanically ventilated after he met with a road traffic accident and sustained extensive maxillofacial injuries and intracranial bleed. A tooth was accidentally aspirated in this injury and progressively resulted in left lower lobe collapse, pneumomediastinum, and consequent difficult ventilation...

BACKGROUND: Radiologic pleuroparenchymal fibroelastosis (PPFE)-like lesion including pulmonary apical cap can be occasionally observed in clinical settings. However, the significance of radiologic PPFE-like lesion is unclear in connective tissue disease (CTD)-related interstitial lung disease (ILD). MATERIALS AND METHODS: A total of 113 patients with CTD-related ILD were enrolled and assessed for radiologic PPFE-like lesion, which was defined as bilateral, upper lobe, and subpleural dense consolidations with or without pleural thickening on chest high-resolution computed tomography...

A 19-year-old male patient was referred by his general practitioner with a new 'cardiac murmur'. For 1 week, he had been able to provoke a clicking sound, which was in time with his heart beat and originated from his chest. The physical examination and laboratory tests were normal. The sound was initially interpreted as most likely due to a valve condition such as mitral valve prolapse, but a transthoracic echocardiogram was normal. A cardiac CT was obtained, which showed left-sided ventral pneumothorax.The Hamman's sign is a loud precordial pulse synchronous sound, which is often postural...

Shared airway management in patients with subglottic stenosis (SGS) is challenging for both the anaesthetist and surgeon. Various methods of airway management have been described but currently no gold standard exists. Jet ventilation has been described as the preferred technique despite a UK National Survey highlighting potential complications including pneumothorax, pneumomediastinum, surgical emphysema, hypoxia and death.

BACKGROUND: Level 1 programs have improved outcomes by expediting the multidisciplinary care of critically ill patients. We established a novel level 1 program for the management of esophageal emergencies. METHODS: After institutional review board approval, we performed a retrospective analysis of patients referred to our level 1 esophageal emergency program from April 2013 through November 2015. A historical comparison group of patients treated for the same diagnosis in the previous 2 years was used...

OBJECTIVE: To assess the efficacy of laryngeal mask airway (LMA) ventilation in obese patients with airway stenosis. STUDY DESIGN: A retrospective chart review was conducted in an academic practice in a tertiary care center. METHODS: We retrospectively reviewed our experience using LMA ventilation in obese patients with airway stenosis. Lowest intraoperative O2 saturation and maximum-end tidal carbon dioxide (CO2 ) levels were recorded. Complications including intubation, unplanned admission, re-admission, postoperative pain, dysphonia, oral trauma, pneumothorax, pneumomediastinum, and tracheostomy were recorded...

We report a 24-year-old man with anti-melanoma differentiation-associated gene-5 (MDA5) antibody-positive dermatomyositis (DM) and interstitial lung disease (ILD) who developed spontaneous pneumomediastinum. By comparing serial thoracic high-resolution computed tomography scans, we demonstrated the distinct time course showing a paradoxical occurrence of pneumomediastinum despite a radiological improvement of ILD. Our case shows that pneumomediastinum in DM can occur regardless of associated ILD and it is a serious complication that should be considered in DM patients presenting with pulmonary manifestations...

Although extraintestinal manifestations of inflammatory bowel diseases are not uncommon, few reports have described concurrent idiopathic thrombocytopenic purpura (ITP). Spontaneous pneumomediastinum is also a rare complication of ulcerative colitis (UC). This report describes the case of a 14-year-old boy who experienced recurrent ulcerative colitis 3 months after temporary improvement following treatment with prednisolone (20 mg/day) and granulocyte/monocyte adsorption apheresis. His platelet counts decreased, suggesting ITP...

Colon perforation is an uncommon but serious complication of colonoscopy. It may occur as either intraperitoneal or extraperitoneal perforation or in combination. The majority of colonic perforations are intraperitoneal, causing air and intracolonic contents to leak into the peritoneal space. Rarely, colonic perforation can be extraperitoneal, leading to the passage of air into the retroperitoneal space causing pneumoretroperitoneum, pneumomediastinum, pneumopericardium, pneumothorax, and subcutaneous emphysema...

A 3.5-y-old Whippet mixed-breed dog was presented with a history of respiratory distress, exercise intolerance, and generalized demodicosis. Hematologic alterations included marked leukocytosis and neutrophilia. Radiographic examination showed a diffuse interstitial and mild peripheral alveolar lung pattern and pneumomediastinum. Because the cytologic examination of the bronchoalveolar aspirate was not diagnostic and a persistent perforation of the upper respiratory tract could not be ruled out, the dog was submitted to thoracoscopy, and subsequently the left cranial lung lobe as well as mediastinal and sternal lymph nodes were resected...
