Unusual Thyroid Mass in an Adolescent Patient.

Hurthle cell tumors are rare follicular-derived thyroid neoplasms. Hurthle cell tumors may be benign or malignant. Workup includes imaging, fine needle aspiration, and treatment usually consists of observation versus thyroidectomy. We describe a case of Hurthle cell adenoma in an adolescent; to the best of our knowledge, this represents only the third case described in the English literature of adolescent Hurthle cell adenoma.

Successful Novel Treatment of Granuloma Faciale Using CO2 Emulated Er:YAG Laser Ablation.

Granuloma faciale is a rare, benign inflammatory skin disease that has multiple medical treatment modalities due to its frequent unresponsiveness to treatment. This skin disease presents as a single, well-demarcated red-brown to violaceous, raised lesion, most commonly on the face, in middle-aged White men. Its etiology is unknown; sun exposure is thought to have some implications in its formation. Treatment modalities for granuloma faciale include topical therapy, intralesional injections, systemic therapies, phototherapy, lasers, cryotherapy, and surgical excision. In this article, we will highlight a rare case of granuloma faciale and its novel and successful treatment with a carbon dioxide emulated Er:YAG laser.

Increased Risk of Autopsy-Proven Pneumonia with Sex, Season and Neurodegenerative Disease.

There has been a markedly renewed interest in factors associated with pneumonia, a leading cause of death worldwide, due to its frequent concurrence with pandemics of influenza and Covid-19 disease. Reported predisposing factors to both bacterial pneumonia and pandemic viral lower respiratory infections are wintertime occurrence, older age, obesity, pre-existing cardiopulmonary conditions and diabetes. Also implicated are age-related neurodegenerative diseases that cause parkinsonism and dementia. We investigated the prevalence of autopsy-proven pneumonia in the Arizona Study of Aging and Neurodegenerative Disorders (AZSAND), a longitudinal clinicopathological study, between the years 2006 and 2019 and before the beginning of the Covid-19 pandemic. Of 691 subjects dying at advanced ages (mean 83.4), pneumonia was diagnosed postmortem in 343 (49.6%). There were 185 subjects without dementia or parkinsonism while clinicopathological diagnoses for the other subjects included 319 with Alzheimer's disease dementia, 127 with idiopathic Parkinson's disease, 72 with dementia with Lewy bodies, 49 with progressive supranuclear palsy and 78 with vascular dementia. Subjects with one or more of these neurodegenerative diseases all had higher pneumonia rates, ranging between 50 and 61%, as compared to those without dementia or parkinsonism (40%). In multivariable logistic regression models, male sex and a non-summer death both had independent contributions (ORs of 1.67 and 1.53) towards the presence of pneumonia at autopsy while the absence of parkinsonism or dementia was a significant negative predictor of pneumonia (OR 0.54). Male sex, dementia and parkinsonism may also be risk factors for Covid-19 pneumonia. The apolipoprotein E4 allele, as well as obesity, chronic obstructive pulmonary disease, diabetes, hypertension, congestive heart failure, cardiomegaly and cigarette smoking history, were not significantly associated with pneumonia, in contradistinction to what has been reported for Covid-19 disease.

Sternoclavicular joint septic arthritis presenting as cervical abscess and subcutaneous emphysema: A case report.

Sternoclavicular joint septic arthritis results from hematogenous spread of a bacterial infection, usually in the immunocompromised. It commonly presents as a chest wall abscess. Cervical abscess resulting from sternoclavicular joint septic arthritis is a rare complication with only one reported case in the English literature. We describe a case of sternoclavicular joint septic arthritis in an elderly diabetic adult with cervical abscess as initial presentation.

Feasibility Study: Comparison of Frontal Cortex Needle Core Versus Open Biopsy for Detection of Characteristic Proteinopathies of Neurodegenerative Diseases.

The clinical diagnosis and classification of neurodegenerative diseases based on clinical examination or available biomarkers are currently insufficiently accurate. Although histologic examination is considered the gold standard for diagnosis, brain biopsies have been avoided because of the high risk-benefit ratio. However, brain biopsies have previously been performed with a craniotomy and excision of approximately 1 cm of cerebral cortex tissue, and it is possible that needle core brain biopsies would have a lower morbidity and mortality risk. Here, we compared the ability of simulated needle core biopsy versus simulated open biopsy to detect the frontal cortex histopathology associated with common neurodegenerative diseases in the elderly using 144 autopsy-proven cases. Simulated needle core biopsy, as compared with simulated open biopsy, gave close to 90% sensitivity and specificity for identifying graded densities of ß-amyloid and neuritic plaques, neurofibrillary tangles, phosphorylated α-synuclein, and phosphorylated TDP-43 pathology. This study shows that the presence and densities of the most common molecular pathologies may be histopathologically assessed in simulated frontal cortex needle biopsies, with accuracy very close to that obtained by open cortical biopsy. An accurate estimation of the morbidity and mortality risk associated with cortical needle core biopsy will require specifically designed clinical trials in appropriate subjects.

Parry-Romberg syndrome in an adult: report of a case.

Parry-Romberg syndrome is an uncommon degenerative disorder characterized by a slow and progressive atrophy of the subcutaneous tissue on one side of the face. Its etiology is unknown, and there is no cure. It is usually seen in children. Surgical reconstruction is often the best treatment option, and a wide variety of techniques have been employed. It is often difficult to diagnose Parry-Romberg syndrome because its signs and symptoms overlap with those of several other disorders. We describe a case of Parry-Romberg syndrome in a 42-year-old woman, whose age at onset was the unusual feature of this case.
