A 3-year-old mixed-breed female cat was diagnosed with a ventricular septal defect of the heart through an echocardiogram. After a 9-month treatment, progressive and diffuse hard thickening of all limbs was observed, which on radiographic examinations, revealed a marked thickening of the long bones. The necropsy findings were limited to the appendicular skeleton and thoracic vertebrae, in addition to a severe cardiac interventricular septal defect and lung edema. The histological evaluation revealed severe replacement of the cortical bone by spongy bone in all bone fragments examined. This is the first report of hypertrophic osteopathy occurring in association with a cardiac malformation in a cat.

Klippel-Feil syndrome is characterized by congenital fusion of two or more cervical vertebrae, a low hair line at the back of the head, restricted neck mobility, and other congenital anomalies. We report a 16-year-old young man with Klippel-Feil syndrome, Sprengel deformity of the right scapula, thoracic kyphoscoliosis, and mandibular prognathism with an anterior open bite. He was treated with orthodontic treatment and maxillofacial surgery. An anticipated difficult airway due to a short neck with restricted neck movements and extrinsic restrictive lung disease due to severe thoracic kyphoscoliosis increased his anesthesia risk. Due to his deviated nasal septum and contralateral inferior turbinate hypertrophy, we chose awake fiber optic orotracheal intubation followed by submental intubation. Considering the cervical vertebral fusion, he was carefully positioned during surgery to avoid potential spinal injury. He recovered well and his postoperative course was uneventful.

A 42-year-old man was diagnosed with cancer of the right lower lung lobe with a posteparterial type of tracheal bronchus, in which the posterior segmental bronchus of the right upper lobe arose from the distal bronchus intermedius. A mass involved the distal bronchus intermedius, requiring a right lower bilobectomy with an additional posterior segmental resection of the right upper lung lobe. Thus, we performed a right lower bilobectomy and sleeve anastomosis of the posterior segmental bronchus of the right upper lobe to the proximal bronchus intermedius, sparing the pulmonary parenchyma of the same lobe.

Heterotaxy syndrome (HS) is a congenital disorder resulting from an abnormal arrangement of visceral organs across the normal left-right axis in the embryonic period. HS is usually associated with multiple anomalies, including defects of the major cardiovascular system and the extracardiovascular system such as intestinal malrotation, abnormal lung lobulation, bronchus anomalies, and pancreatic dysplasia. Although pancreatic dysplasia is occasionally accompanied with HS, the occurrence of diabetes mellitus (DM) due to pancreatic dysplasia in HS is rarely reported. We here report a case involving 13-year-old girl with DM caused by agenesis of the dorsal pancreas and HS diagnosed on the basis of the presence of a double-outlet right ventricle with bilateral pulmonary stenosis and intestinal malrotation with duodenal cyst. Timely diagnosis and treatment with insulin improved glycemic control.

A 56-year-old Chinese man presented with giddiness and vertigo. Subsequent chest radiography showed the classic scimitar sign of an abnormal pulmonary venous return. Further evaluation with non-contrast computed tomography substantiated the finding of a partial anomalous venous drainage pattern and identified an associated rare lung anomaly, horseshoe lung. The imaging findings of scimitar syndrome and its association with horseshoe lung are reviewed.

We reviewed the data of 38 neonates who died of respiratory failure. Paraffin sections of the autopsy lung samples were examined with HE staining or immunolabeling for CD34, CD68 and CK to observe the development of the pulmonary vessels and detect potential pulmonary vascular diseases (PVDs). Five cases were identified to have PVDs, including pulmonary hypertensive vascular remodeling in 3 cases and alveolar capillary dysplasia in 2 cases. The result indicated that PVD was one of the important reasons for respiratory failure in these neonates.

We report a case of an entrapped lung after the pectus bar repair of a pectus deformity. The entrapped lung was found incidentally during video-assisted thoracoscopic surgery (VATS) for pneumothorax. Based on VATS exploration, multiple bullae seemed to be the cause of the pneumothorax, but the entrapped lung was suspected to have been a cause of the air leakage.

OBJECTIVETo study the etiology, pathogenesis, clinicopathologic characteristics, prognosis and treatment of congenital pulmonary airway malformation (CPAM).

METHODSEighteen cases of CPAM were enrolled into the study. The clinical history, autopsy findings and immunohistochemical results were evaluated, with review of literature. The pathogenetic mechanism, pathologic features and differential diagnosis of CPAM were studied.

RESULTSHistologic examination showed that 2 cases were classified as Stocker type I, 12 cases as type II, and 4 cases as type III. The lesion was unilateral and involved single lobe in 13 cases. The remaining 5 cases had bilateral diseases. Of the 18 cases studied, 12 cases showed single organ involvement and 6 cases had malformations affecting multiple organs. The associated malformations included cardiac anomalies (4 cases), polycystic kidney with gastrointestinal atresia (1 case) and nuchal cystic hygroma with hydrothorax (1 case).

CONCLUSIONSCPAM is a rare pulmonary disorder. The etiology of this non-neoplastic condition is unknown. Imaging analysis is a valuable tool to suggest CPAM, while definite diagnosis requires pathologic examination. The overall prognosis is determined by the presence of associated malformations, fetal hydrops and pulmonary hypoplasia.

Pulmonary systemic arterialization to normal basal lung without sequestration is a rare congenital anomaly. In this rare abnormality, arterialization of the left lower lobe is the most common type. In general, surgical treatments have been performed. Recently, for reducing the complications and risks of surgery, embolization is mainly attempted by using coils. We report a case of 22-year-old male patient with a 10 mm anomalous arterial supply to his normal lung, which is being successfully treated by transcatheter embolization when using the Amplatzer Vascular Plug that has been adapted for the treatment of high-flows and large artery occlusions.

Ambient air pollution, including particulate matter (PM) and gaseous pollutants, represents an important environmental factor that adversely affects human health. PM is a complex mixture of extremely small particles and liquid droplets. Particle pollution is made up of a number of components, including acids (such as nitrates and sulfates), organic chemicals, metals, and soil or dust particles. Subtypes of atmospheric PM include suspended particulate matter, respirable suspended particles (particles with a diameter of 10 microm or less), fine particles (diameter of 2.5 microm or less), ultrafine particles, and soot. Sources of particulate matter can be artificial or natural. The effects of inhaling PM that have been widely studied in humans and animals now include asthma, lung cancer, cardiovascular mortality, respiratory diseases, birth defects, and premature death. This review focus on the impact of PM on health outcomes such as respiratory disease, heart disease, and cancer.
