Cutaneous Findings of Sporadic, Adult-Onset Neuronal Intranuclear Inclusion Disease.

Am J Dermatopathol 2022 Jan;44(1):1-6

Professor of Pathology, Department of Pathology, Massachusetts General Hospital, Harvard Medical School, Boston, MA.

Abstract: Neuronal intranuclear inclusion disease is a rare, progressive neurodegenerative disease whose hallmark histopathologic finding is the presence of ubiquitin-positive hyaline intranuclear inclusions in neuronal and non-neuronal cells. We present a case of neuronal intranuclear inclusion disease in a 61-year-old Asian man with a history of repeated episodes of altered mental status, long-standing bladder dysfunction, and cerebrovascular accidents. The patient had characteristic magnetic imaging findings of high signal along the cortico-medullary junction on diffusion-weighted sequences and symmetric T2 hyperintensity in the paravermal area of the cerebellum.

Artificial osteochondral interface of bioactive fibrous membranes mediating calcified cartilage reconstruction.

J Mater Chem B 2021 09 29;9(37):7782-7792. Epub 2021 Sep 29.

Bio-nanomaterials and Regenerative Medicine Research Division, Zhejiang-California International Nanosystem Institute, Zhejiang University, Hangzhou 310058, China.

Calcified cartilage is a mineralized osteochondral interface region between the hyaline cartilage and subchondral bone. There are few reported artificial biomaterials that could offer bioactivities for substantial reconstruction of calcified cartilage. Herein we developed new poly(L-lactide--caprolactone) (PLCL)-based trilayered fibrous membranes as a functional interface for calcified cartilage reconstruction and superficial cartilage restoration.

In 2003, we briefly reported the remarkable osteopathy of a 12-year-old boy who at age two months began fracturing his limbs with subsequent hyperplastic callus formation and expansion and fusion of appendicular bones. By age ten years he had coalesced his lumbosacral spine, pelvis, femurs, and leg and foot bones as a single structure. Computed tomography of expanded bone revealed a thin cortical shell, diminished irregular trabeculae, and cystic areas. Read More

Radiologic Features of Type II and Type XI Collagenopathies.

Radiographics 2021 Jan-Feb;41(1):192-209. Epub 2020 Nov 13.

From the Department of Radiology, University of Iowa Hospitals and Clinics, 200 Hawkins Dr, Iowa City, IA 52242 (A.H.); Department of Molecular Medicine and Surgery, Center for Molecular Medicine, Karolinska Institutet and Department of Clinical Genetics, Karolinska University Hospital, Stockholm, Sweden (G.G.); and Center for Intractable Diseases, Saitama Medical University Hospital, Saitama, Japan (G.N.).

Type II collagen is a major component of the cartilage matrix. Pathogenic variants (ie, disease-causing aberrations) in the type II collagen gene lead to an abnormal structure of type II collagen, causing a large group of skeletal dysplasias termed Because type II collagen is also located in the vitreous body of the eyes and inner ears, type II collagenopathies are commonly associated with vitreoretinal degeneration and hearing impairment. Type II collagenopathies can be radiologically divided into two major groups: the spondyloepiphyseal dysplasia congenita (SEDC) group and the Kniest-Stickler group. Read More

Novel homozygous missense mutation in ABCA3 protein leading to severe respiratory distress in term infant.

BMJ Case Rep 2020 Oct 10;13(10). Epub 2020 Oct 10.

Neonatology, Madhukar Rainbow Children Hospital, Delhi, India.

The term baby presented with respiratory distress with X-ray pictures consistent as hyaline membrane disease (HMD). Baby was ventilated and treated with surfactant. Because of the persistence of high ventilation needs with X-ray pictures consistent with HMD with a transient response to surfactant every time, the possibility of an inherited disorder of surfactant metabolism was kept.

Plasminogen improves lung lesions and hypoxemia in patients with COVID-19.

QJM 2020 Aug;113(8):539-545

Department of Basic Research, Talengen Institute of Life Sciences, Shenzhen, P.R. China.

Background: Lungs from patients with coronavirus disease 2019 (COVID-19) have shown typical signs of acute respiratory distress syndrome (ARDS), formation of hyaline membrane mainly composed of fibrin and 'ground-glass' opacity. Previously, we showed plasminogen itself is a key regulator in fibrin degradation, wound healing and infection.

Tension pneumocephalus, an uncommon complication of oxygen therapy in preterm newborns. Presentation of a case and literature review.

Neurocirugia (Astur : Engl Ed) 2021 Mar-Apr;32(2):84-88. Epub 2019 Nov 26.

Servicio de Neurocirugía, Complejo Hospitalario Universitario de Santiago de Compostela, Santiago de Compostela, A Coruña, España.

Tension pneumocephalus is an extremely rare complication of positive-pressure ventilation in neonates, the diagnosis of which requires a high degree of clinical suspicion. We present the case of a preterm newborn, who received high-flow nasal cannula oxygen therapy because of hyaline membrane disease, due to his prematurity, and developed clinical signs of intracranial hypertension. Transfontanellar ultrasound and cranial CT scan revealed significant tension pneumocephalus, which was evacuated with direct needle puncture through the anterior fontanelle. Read More

Tenosynovial Giant Cell Tumor, Localized Type With Extensive Chondroid Metaplasia: A Case Report With Immunohistochemical and Molecular Genetic Analysis.

Int J Surg Pathol 2020 Jun 26;28(4):447-453. Epub 2019 Nov 26.

Shimane University, Izumo, Shimane, Japan.

Tenosynovial giant cell tumor (TSGCT) of localized type is a common disease occurring mostly in the hands. Diagnosis of this tumor is relatively easy to render with hematoxylin-eosin-stained sections as compared with that of TSGCT of diffuse type. However, very rare cases with chondroid metaplasia that have recently been reported mainly in diffuse type can make pathological differentiation from soft tissue cartilaginous tumors extremely difficult.

Alveolar epithelial cells undergo epithelial-mesenchymal transition in acute interstitial pneumonia: a case report.

BMC Pulm Med 2014 Apr 23;14:67. Epub 2014 Apr 23.

Department of Pulmonary medicine, Binzhou Medical University Hospital, Binzhou, P,R, China.

Background: Acute interstitial pneumonia is a rare interstitial lung disease that rapidly progresses to respiratory failure or death. Several studies showed that myofibroblast plays an important role in the evolution of diffuse alveolar damage, which is the typical feature of acute interstitial pneumonia. However, no evidence exists whether alveolar epithelial cells are an additional source of myofibroblasts via epithelial-mesenchymal transition in acute interstitial pneumonia. Read More

Direct imaging of pH1N1 2009 influenza virus replication in alveolar pneumocytes in fatal cases by transmission electron microscopy.

J Electron Microsc (Tokyo) 2011 21;60(1):89-93. Epub 2011 Jan 21.

National Institute of Virology, 20A Dr Ambedkar Road, Pune 411001, India.

Human influenza virus pandemics constitute a major global public health issue. Although studies on autopsy specimens from the recent pandemic by the 2009 influenza A (H1N1) virus have revealed a broad spectrum of pathologic findings, direct electron microscopic studies of the lung tissue from influenza fatalities are few. In this study, we examined five well-preserved pulmonary necropsy specimens from fatal cases of laboratory-confirmed pH1N1 from India. Read More
