Pictorial essay of radiological features of benign intrathoracic masses.

With increased exposure of patients to routine imaging, incidental benign intrathoracic masses are frequently recognized. Most have classical imaging features, which are pathognomonic for their benignity. The aim of this pictorial review is to educate the reader of radiological features of several types of intrathoracic masses.

Radiation Dose-rate Reduction Pattern in Well-differentiated Thyroid Cancer Treated with I-131.

Objective: To determine the patterns of dose rate reduction in single and multiple radioiodine (I-131) therapies in cases of well differentiated thyroid cancer patients.

Study Design: Analytical series.

Place And Duration Of Study: Department of Nuclear Medicine and Radiation Physics, Multan Institute of Nuclear Medicine and Radiotherapy (MINAR), Multan, Pakistan, from December 2006 to December 2013.

Phospholipases A2: enzymatic assay for snake venom (Naja naja karachiensis) with their neutralization by medicinal plants of Pakistan.

Phospholipases A2 (PLA2) are the most lethal and noxious component of Naja naja karachiensis venom. They are engaged to induce severe toxicities after their penetration in victims. Present study was designed to highlight hydrolytic actions of PLA.

Preparation and radiochemical control of 99mTc labeled blood pool agent for in vivo labelling of the red blood cells.

Our aim was to prepare cheap blood pool imaging kits by simplified method to overcome the burden on purchase department of MINAR, Nishtar Hospital, Multan, Pakistan. Secondarily, prompt supply of kits should save the time of patient during transportation. A total of 24 subjects selected for this study were equally divided into two groups.

Naja naja karachiensis envenomation: biochemical parameters for cardiac, liver, and renal damage along with their neutralization by medicinal plants.

Naja naja karachiensis envenomation was found to hit more drastically heart, liver, and kidneys. 400 μg/kg of venom-raised moderate serum levels of ALT (72 ± 4.70 U/L, 0.

Gist of medicinal plants of Pakistan having ethnobotanical evidences to crush renal calculi (kidney stones).

Human civilization is facing the problem of kidney stones since ancient ages. Although mortality rate is not so high, yet it affects the victim's quality of life. The patient suffers from intense pain and many other symptoms modifying his life style and affecting his socioeconomic status.

Ultrasound diagnosis of dicephalic conjoined twins at 24 weeks of gestation.

We report the case of dicephalic conjoined twins discovered incidentally on a routine ultrasound at 24 weeks of gestation. There were 2 heads and a neck that fused with 1 thorax, but the spines continued all the way to the coccyx. The spines were connected medially by a fused rib, and laterally, there were ribs that went around the thorax in a more normal fashion.

Klippel-Trenaunay syndrome.

Klippel-Trenaunay Syndrome (KTS) is a rare, congenital, vascular disorder affecting one or more limbs. Originally, it was defined as a triad including port wine stain, varicose veins and bony and soft tissue hypertrophy. We present a case of a 20-year-old female who walked with a limp.

Carcinoembryonic antigen (CEA) levels in hookah smokers, cigarette smokers and non-smokers.

Objective: To find CEA levels in smokers of different categories (hookah smokers, cigarette smokers smoking different brands of cigarettes and different number of cigarettes per day) and to correlate CEA levels with type and rate of smoking.

Methods: A total of 122 cigarette smokers (115 men and 7 women) and 14 hookah smokers (all men) with age ranging from 16-80 years were studied. CEA levels were also measured in 36 non-smokers who served as controls.

Studies of gastric emptying time in patients with non-ulcer dyspepsia.

Purpose: To assess the gastric emptying pattern of a standardized solid meal in patients with non-ulcer dyspepsia by using scintigraphic techniques.

Methods: Results for the half-emptying time for solids (T1/2) and percent clearance of solid meal at 60 min (C60) of patients (n=35) having non-ulcer dyspepsia according to Rome II criteria were compared with age- and sex-matched controls (n=28). Gastric emptying was studied by using egg omelette labelled with Tc tin colloid.

Sonographic mimics of renal calculi.

Objectives: To review sonographic findings that can mimic renal calculi.

Methods: We comment on a number of echoes that can mimic renal calculi.

Results: There are a number of sonographic renal artifacts, vascular and nonvascular, that may confound a correct diagnosis.

Prenatal sonographic diagnosis of Neu-Laxova syndrome.

We report the sonographic diagnosis of Neu-Laxova syndrome in a fetus at 27 weeks' menstrual age. The parents were first cousins. Sonography revealed microcephaly, a sloping forehead, exophthalmos, a small thorax and abdomen, hypoplastic lungs, syndactyly, hyperextended knees, polyhydramnios, a small placenta, and intrauterine growth restriction.

"Congealed waterlilly" sign: a new sonographic sign of liver hydatid cyst.

The ultrasonographic (US) appearance of hydatid liver disease is well established, but solid cysts have long defied US characterization. We present 23 solid cysts and describe a new feature called the "Congealed waterlilly" sign. As the physical characteristics of the hydatid fluid change from watery to a viscid gel, it becomes echogenic.
