Bladder cancer in a young patient: Undiscovered risk factors.

Bladder cancer is one of the most common forms of malignancies involving the urinary system and multiple risk factors have been associated with its etiology. The most common of which include cigarette smoking and various occupational or chemical exposures. It is usually diagnosed in older individuals with an average age of 70. In rare cases it is observed in children as well as young adults where it usually presents as a low-grade, non-invasive disease. In the present case report a 27-year-old male patient is discussed: The patient presented with no significant risk factors and was treated for mucinous adenocarcinoma of the bladder while further investigations were performed to identify other associated factors related to this form of malignancy. Debate in the literature exists in regards to the characteristics of bladder neoplasms in younger patients compared with older patients, however there is a lack of research into the etiology or prognosis in young patients. The present case study illustrates the case of a young adult with no clear risk factors who was diagnosed with a rare case of mucinous adenocarcinoma of the bladder.

A New Variant of Combined Pulmonary Fibrosis and Emphysema From Second-Hand Smoke: A Case Report and Review of Literature.

The findings of combined pulmonary fibrosis along with emphysema have been increasingly recognized in the medical literature. Patients presenting with such findings are usually found to be heavy smokers or former smokers. Their presentations begin with severe respiratory distress that gets progressively worse. They are found to have low diffusion capacity (DLCO) although spirometry will show preserved lung volumes. No prior research has presented a documented case of such a fatal condition in a young person with no prior history of smoking. In this case report, we discuss the presentation, diagnosis, and management of a young 29-year-old non-smoker with increasing shortness of breath with a complicated hospital course discovered to have an abnormal variant or presentation of "combined pulmonary fibrosis and emphysema" (CPFE). As most published studies have attributed these findings as a secondary response to a history of smoking, other etiologies and risk factors have yet to be properly analyzed resulting in prolonged hospital course and often missed diagnoses.

Paranoid personality masking an atypical case of frontotemporal dementia.

Frontotemporal dementia (FTD) is a debilitating disease that is well described in the "Diagnostic and statistical manual of mental disorders, fifth edition (DSM-5)", and typically presents with memory impairment, progressive decline in cortical functioning, and behavioral changes. Age of onset is generally in the late fifties, and usually the first presentation involves a change in behavior and emotional blunting. Treatment of FTD involves management of any neurobehavioral symptoms while trials of atypical antipsychotics are ongoing but suggest some efficacy. We present a case of a patient who first presented with severe paranoid personality traits and frank persecutory delusions. This atypical presentation of our patient first led to her incorrect diagnosis of a psychotic disorder and paranoid personality disorder. As a result of this diagnosis, she was treated unsuccessfully. A subsequent magnetic resonance imaging (MRI) then showed atrophy of frontal and temporal lobes bilaterally (left more prominent than right) which confirmed the diagnosis of FTD. The importance of this case involves the atypical presentation of paranoia and delusions, and our patient's incorrect diagnosis based on her clinical presentation led to a trial of unsuccessful treatment. Only after performing an MRI, which showed atrophy, was the patient appropriately treated and deemed medically stable. This case report illustrates the importance of considering a rare presentation of frontotemporal lobe dementia with patients who are in the typical age range and present with paranoia and delusions.

Myopericarditis: A Diagnosis of Uncertainty.

Myocarditis can present in many different forms and can be overlooked by more life-threatening conditions. At times it may mimic conditions such as acute myocardial infarction and although it may have features highly suggestive of myocarditis, other etiologies need to be excluded. Thus, due to its clinical presentation, lab findings, and electrocardiogram analysis, it often can be confused with other conditions, making it a diagnostic dilemma of uncertainty. Myopericarditis is normally caused by viral infections, most common of which is coxsackievirus. Here we report a case of a 52-year-old gentleman who presented with a clinical picture of acute myocardial ischemia versus dissection, which overlooked a rather less threatening etiology of myopericarditis.
