Purulent constrictive pericarditis caused by Salmonella enteritidis in a patient with adult-onset Still's disease: A case report.

Rationale: Purulent pericarditis is a rare and usually fatal disease. Immunodeficiency state and preexisting pericardial effusion can predispose patients to infections. However, we are not aware of similar cases in patients with adult-onset Still's disease (AOSD).

Robotic totally endoscopic coronary artery bypass for isolated ostial stenosis of the left coronary artery.

Isolated ostial stenosis (IOS) is a rare disease that encroaches on aorto-coronary junction of uncertain etiology. All distal coronary vessels present normally. IOS occurs predominantly in premenopausal young women with few risk factors for atherosclerotic disease.

Ectopic Thyroid Tissue in the Adrenal Gland Mimicking a Pheochromocytoma.

Ectopic thyroid tissue in the adrenal gland (ETTAG) usually presents as a well-circumscribed cystic mass on a CT scan. However, the MRI features of ETTAG are incompletely understood. We report a case of ectopic thyroid tissue in the adrenal gland, which demonstrates findings similar to those of a pheochromocytoma on the MRI.

Comprehensive screening for MED12 mutations in gynaecological mesenchymal tumours identified morphologically distinctive mixed epithelial and stromal tumours.

Aims: MED12 exon 2 mutations have been identified in most uterine leiomyomas and mammary fibroepithelial tumours. MED12 has not been genotyped in most other gynaecological mesenchymal tumours. The purpose of this study was to determine the prevalence of MED12 mutations in uncommon gynaecological mesenchymal tumours.

Clinical parameters associated with absence of endocervical/transformation zone component in conventional cervical Papanicolaou smears.

Objective: To study clinical factors predicting the absence of endocervical/transformation zone (EC/TZ) components of conventional cervical Papanicolaou (Pap) smears.

Materials And Methods: The medical charts of patients who received Pap smears between March 2006 and August 2006 in the hospital were reviewed. The results of their Pap smears were retrieved while their demographic and clinical information were obtained from the medical charts.

Ultraviolet/blue light-emitting diodes based on single horizontal ZnO microrod/GaN heterojunction.

We report electroluminescence (EL) from single horizontal ZnO microrod (MR) and p-GaN heterojunction light-emitting diodes under forward and reverse bias. EL spectra were composed of two blue emissions centered at 431 and 490 nm under forward biases, but were dominated by a ultraviolet (UV) emission located at 380 nm from n-ZnO MR under high reverse biases. Light-output-current characteristic of the UV emission reveals that the rate of radiative recombination is faster than that of the nonradiative recombination.

Malignant solitary fibrous tumor of the urinary bladder.

A 67-year-old man was examined for persistent pain over his lower abdomen and was found to have a large pelvic tumor. During surgery, we detected a 16 × 9 × 9 cm(3) urinary bladder tumor with small intestinal adhesions, and performed partial cystectomy and segmental resection. Histological and immunohistochemical examinations established the diagnosis of malignant solitary fibrous tumor (SFT).

Renal mucinous tubular and spindle cell carcinoma with an aorto-caval mass mimicking metastatic lymphadenopathy.

A 54-year-old female had a 9-cm left renal mass with a 12-cm aorto-caval mass lesion mimicking an enlarged lymph node. Retroperitoneal dissection and left radical nephrectomy were performed, and pathology revealed a left renal mucinous tubular and spindle cell carcinoma combined with a retroperitoneal ganglioneuroma. The patient has had no local recurrence or distant metastasis after 3 years' follow-up.

Invasive adenocarcinoma of the prostate with urethral tumor.

Metastases of prostate cancer to the penis and urethra are rare and often represent advanced disease. We describe a case of newly diagnosed prostatic adenocarcinoma with metastases to the corpus spongiosum, cavernosum, and the anterior urethra. A male patient, 77 years of age, initially had lower urinary tract obstruction symptoms.

Neuroimaging and quality-of-life outcomes in patients with brain metastasis and peritumoral edema who undergo Gamma Knife surgery.

Object: Gamma Knife surgery (GKS) has been shown to be effective for treating many patients with brain metastasis. Some brain metastases demonstrate significant peritumoral edema; radiation may induce cerebral edema or worsening preexisting edema. This study was conducted to evaluate the imaging and neurobehavioral outcomes in patients with preexisting peritumoral edema who then undergo GKS.

Therapy conversion to biphasic insulin aspart 30 improves long-term outcomes and reduces the costs of type 2 diabetes in Saudi Arabia.

Objective: An observational study in Saudi Arabia indicated that conversion to biphasic insulin aspart 30 (BIAsp 30) from human insulin (HI) was associated with improvement of glycaemic control.

Methods: A validated computer simulation model of diabetes was used to project long-term outcomes (such as quality-adjusted life expectancy and direct medical costs) based on patient characteristics and treatment effects observed in the Saudi Arabian PRESENT subgroup (n=598). Baseline prevalence of comorbidities was obtained from published sources.

Assessment with magnetic resonance imaging and spectroscopy in Lhermitte-Duclos disease.

Lhermitte-Duclos disease (LDD) is a rare benign lesion of uncertain pathogenesis characterized by distortion of the normal cerebellar laminar cytoarchitecture. We report a 22-year-old man admitted for injury sustained in a traffic accident with the incidental finding of a cerebellar mass. Magnetic resonance imaging (MRI) revealed a mass lesion within the right cerebellar hemisphere.

Colorectal mesenchymal tumor: a clinicopathologic study of 25 cases.

Background: It is important to distinguish gastrointestinal stromal tumors (GISTs) from other gastrointestinal mesenchymal tumors (GIMTs), because of the malignant potential of GISTs and the availability of molecular targeted therapy. GISTs represent the most common subgroup of GIMTs, and rarely occur in the colon and rectum. The first objective of our retrospective study was to reclassify colorectal mesenchymal tumors, from files collected over 20 years, to determine if, based on immunohistologic features, the lesions were truly GISTs.
