Pulmonary localized hamartomas were first reported in 1906 by Hart(1). Hamartoma is the most common benign neoplasm to occur in the lung. Histologically, the lesions consist of a combination of cartilage, connective tissue, smooth muscle, fat, and respiratory epithelium. Malign transformation is rare (2,3). Pulmonary hamartomas occur more common in males. However, some authors reported male/fem...

Many large graphs can be constructed from existing smaller graphs by using graph operations, for example, the Cartesian product and the lexicographic product. Many properties of such large graphs are closely related to those of the corresponding smaller ones. In this short note, we give some properties of the lexicographic products of vertextransitive and of edge-transitive graphs. In particula...

An 84-year-old female with hypertension and end-stage kidney disease on dialysis was admitted for sudden and massive hematochezia, hypovolemic shock, and severe anemia (hemoglobin 6.9 g/dL). A full colonoscopy with ileoscopy revealed bright red blood through the entire colon and multiple diverticula in the descending and sigmoid colon (Figure 1). After several passages and water irrigation, a d...

A 40-year-old man with a history of hypertrophic cardiomyopathy, progressive dyspnea and refractory ascites was referred to our hospital for heart transplantation. The patient underwent heart transplantation successfully from female donor who died of intracranial hemorrhage. After heart transplantation, the patient recovered uneventfully and discharged 1 month later. By chance, we found a linea...

A 27-year-old female patient presented to our clinic because of atypical chest pain. Her past medical history was unremarkable for any chronic illness. Her vital signs comprised a heart rate of 85 bpm, blood pressure of 125/70 mm Hg, and oxygen saturation of 98%. Physical examination was unremarkable. Electrocardiography showed normal sinus rhythm without any ST-segment and T-wave abnormalities...

A 59-year-old female with frequent, drug-refractory ventricular premature beats (VPBs) was referred for catheter ablation. On her resting ECG, monomorphic VPBs were present in bigeminic pattern with axis similar to sinus rhythm, transition zone in lead V3 and slurring in leads III, V2, and V3 (Figure 1A). During the procedure, the earliest ventricular activation site was localized just below th...

A 12-month-old female infant was referred to our hospital with prolonged fever and status epilepticus. Her weight and height were below the 5th percentile for age. Physical examination revealed marked hypotonia, fever, pallor, partial albinism with silvery gray hair, and hepatosplenomegaly (Figure 1A). Laboratory investigations showed anemia, thrombocytopenia, hypofibrinogenemia, hyperferritine...

A factorisation of a complete graph Kn is a partition of its edges with each part corresponding to a spanning subgraph (not necessarily connected), called a factor. A factorisation is called homogeneous if there are subgroups M <G ≤ Sn such that M is vertex-transitive and fixes each factor setwise, and G permutes the factors transitively. We classify the homogeneous factorisations of Kn for whi...

Men and women at Northwest University (n=751), Xi’an, China were asked to judge the attractiveness of photographs of female patients who had undergone micrograft surgery to reduce their waist-to-hip ratios (WHR). Micrograft surgery involves harvesting adipose tissue from the waist and reshaping the buttocks to produce a low WHR and an ‘hourglass’ female figure. This gynoid distribution of femal...
