Twenty-five patients with primary biliary cirrhosis (PBC) in different stages were investigated with respect to pulmonary function abnormalities. The results were compared with a reference sample of 17 sex- and age-matched healthy subjects. A high prevalence of lung function impairment was found in the PBC patients (14/25 [56%]). Bronchial asthma was present in three patients, and severe lung emphysema in one. These four patients had an abnormal lung function, mainly of obstructive type. There was a statistically significant difference between the remaining 21 PBC patients without chronic obstructive lung disease and the reference subjects with respect to diffusion capacity. Almost all abnormal lung function data were found in the symptomatic PBC patients (i.e. symptoms of pruritus, xanthoma, xanthelasmata, jaundice, hyperpigmentation, hepatosplenomegaly), 13 out of 18 (72%), whereas only one out of seven asymptomatic patients was affected. Nine patients (36%) had reduced diffusion capacity compared with none of the reference subjects. The lung function abnormalities in PBC patients are similar to those found in sarcoidosis, another granulomatous disease.

A 54-year-old Caucasian male had a witnessed collapse on the street. He was transported to the emergency department and subsequently pronounced dead. An unlimited autopsy examination was conducted under authorization of the coroner. Medical record review later revealed that the decedent had a history of alcohol abuse, chronic obstructive pulmonary disease, congestive heart failure, and chronic osteomyelitis treated by minocycline 100 mg twice daily. Autopsy revealed the cause of death to be ruptured gastroesophageal varices with nearly one liter of recent hemorrhage in the stomach and gastrointestinal tract. Other findings compatible with a history of alcoholism included hepatosplenomegaly, hepatic steatosis, and early bridging fibrosis. The decedent's thyroid was multinodular and enlarged at 50 gm. The thyroid gland, in its entirety, is shown below with serial sections made longitudinally through the gland capsule to reveal the underlying parenchyma.

Cytomegalovirus (CMV) is currently the most common cause of congenital infection and the leading infectious cause of brain damage and hearing loss in children. Perinatal CMV infection rarely causes clinical manifestations in normal individuals and usually follows a benign course in immunocompetent infants. However, ~15-25% of infected preterm infants may develop pneumonia, hepatitis or sepsis-like illness, bradycardia, hepatosplenomegaly, distended bowel, anemia, or thrombocytopenia. Bronchiolitis obliterans (BO) is a rare, fibrosing form of chronic obstructive lung disease that follows severe insults to the lower respiratory tract and results in narrowing and/or complete obliteration of the small airways. In non-transplant children, the most common form of BO is a severe lower respiratory tract infection, especially of adenovirus. We experienced a case of a 37-day-old male who was diagnosed as BO on chest computed tomography (CT) after CMV pneumonia. To our best knowledge, this is the first case of BO caused by CMV pneumonia in a healthy infant.

AL amyloidosis is due to deposition of protein derived from immunoglobulin light chain fragments. It is a systemic disorder in which deposition of plasma proteins can adversely affect function of the heart, liver, kidneys, and peripheral nerves. Deposition in the heart results in a decrease in the amplitude of the electrical activity of the heart and can be an early clue to the diagnosis. A 63-year-old male admitted for volume overload was found to have nephrotic range proteinuria, progressive renal insufficiency (Creatinine 4.0 increased from his baseline 0.9), and hypoalbuminemia. On exam, he had diffuse anasarca and peripheral neuropathy. A renal biopsy showed AL amyloidosis, lambda related, involving the glomeruli, interstitium, and arterial walls. Bone marrow biopsy showed 30% plasma cells with lambda light chain predominance. Serum free light chains were elevated. Lamda was 11.50 mg/dL and kappa was 5.12 mg/dL. In retrospective review of his chart, an EKG with low voltage and anterior pseudo-infarct pattern was first apparent on an admission for stroke two years prior. Echocardiogram showed mild concentric left ventricular hypertrophy. The patient was started on chemotherapy with Bortezomib. The differential of a low-voltage EKG includes many common pulmonary and chest wall (COPD, obesity) as well as pericardial diseases (effusions), but also important rarer infiltrative diseases including sarcoidosis and amyloidosis. Amyloidosis of the heart can cause progressive irreversible heart failure, but its progress can be altered if identified early. Physicians should consider amyloidosis when faced with a low-voltage EKG along with systemic symptoms including nephrotic range proteinuria, peripheral neuropathy, hepatosplenomegaly, and macroglossia.

The presence of erythrocytosis along with the diagnosis of chronic obstructive pulmonary disease (COPD) may veer a primary care clinician in a busy clinic towards attributing the erythrocytosis to hypoxia secondary to COPD; however, this is not always the case. This case highlights the importance of investigation and the significance not excluding a primary cause in COPD patients with erythrocytosis. A 57-year-old male, presenting with chronic cough, was subsequently diagnosed with COPD clinically and confirmed by spirometry. Erythrocytosis was also incidentally noted. The patient did not have any symptoms of polycythemia or hepatosplenomegaly. Therefore, the erythrocytosis was initially thought to be caused by hypoxia secondary to COPD. However, the JAK2 V617F gene mutation was detected and hence the diagnosis of polycythemia vera was made. Although the erythrocytosis was initially attributed secondary to the underlying pulmonary disease, investigations proved it to be primary in origin. This case report highlights the importance of investigating the underlying cause and to confirm the diagnosis of erythrocytosis as primary and secondary polycythemia differ in their management approach. This will avoid inappropriate diagnosis, treatment, and undesirable outcomes.
