Persistent hydropneumothorax was diagnosed in a 62-year-old female with a history of blunt trauma, although she was treated with chest tube and closed underwater seal drainage. Computed tomography and fiberoptic bronchoscopy findings were consistent with "fallen lung" syndrome. Fiberoptic bronchoscopy also found a cavitary lesion at the right tracheobronchial angle.

Clinical significance of segmental lung perfusion defects in children with bronchiolitis obliterans (BO), have not been reported before. The aim of this study was to evaluate clinical significance of lung perfusion defects in children with BO and to reveal its impact on follow up. The study included 38 children aged 9 to 60 months (17.

Purpose: To retrospectively document the reported computerized tomography (CT) and magnetic resonance imaging (MRI) examinations that were left behind in our radiology department, to calculate their cost, and to determine possible sources of waste in order to draw attention to this subject.

Materials And Methods: The reported and billed CT and MRI examinations for 2003 that were not taken from the radiology department were documented, and the percentage they represented of all CT and MRI performed that year were determined. The total cost of the examinations, including contrast media, was calculated.

Objectives: We aimed to determine the perfusion differences according to the histological type, stage, volume and prognoses in the non-small cell carcinoma by thorax perfusion CT.

Materials And Methods: Twenty-four non-small cell carcinoma patients were included in the study. Thorax perfusion CT was done to evaluate the tumors in terms of perfusion parameters: blood flow (BF) and time to peak (TTP) values.

Background & Objectives: Mammographic screening is an effective tool for the early detection of breast cancer. Hormone replacement therapy (HRT) has been shown to increase mammographic density and thus may hinder early detection of small tumours. We undertook this study to determine and compare the frequency and degree of change in mammographic density in postmenopausal women in HRT using two different methods: the classical Wolfe classification and a new semiquantitative method, which we named as the comparison wheel.

The aim of the study was to ascertain whether spiking of the tibial tubercle is associated with cartilage defects detected by magnetic resonance imaging (MRI) in patients with osteoarthritis (OA) of the knee joint. Angulation of the tip of the medial and lateral tubercles, and the height of the tubercles above the tibial plateau were measured on a standard anteroposterior radiograph of the knee joint. Cartilage defects in the tibiofemoral joint (TFJ) were determined by MRI examination.

We report a case of rhinocerebral mucormycosis associated with an abscess in the lateral aspect of the pons associated with perineural spread of disease via the trigeminal nerve. Contrast enhanced MRI was useful in depicting the extent of the disease and suggesting perineural spread. A pathological diagnosis of mucormycosis was established by means of rhino-orbital punch biopsy.

Article Synopsis
  • Barium sulphate is a widely used contrast medium for imaging the gastrointestinal tract and is generally considered safe.
  • Allergies to barium sulphate are extremely rare.
  • A case is reported involving a 24-year-old woman who experienced an allergic reaction during an upper gastrointestinal study.

Article Synopsis
  • - Recent studies have found that high-resolution computed tomography (HRCT) can identify permanent structural changes in chronic asthma that regular chest X-rays cannot detect.
  • - The research involved 28 stable asthmatic patients and 10 healthy controls, assessing differences in airway thickness and other metrics between mild and severe asthma cases.
  • - Significant findings included more frequent occurrences of air trapping and bronchiectasis in asthmatic patients, but no clear correlation was found between HRCT changes and the severity of asthma, suggesting that identifying these changes early could enhance asthma treatment strategies.

This study was designed to evaluate the effects of propofol alone and propofol-clonidine combination on human middle cerebral artery blood flow velocity (Vmca) and cerebrovascular carbon dioxide (CO2) response by using transcranial Doppler ultrasonography. Mean Vmca in response to changes in arterial partial pressure of CO2 (Paco2) was determined under the following conditions: awake (group 1), propofol anesthesia (group 2), and combined propofol-clonidine anesthesia (group 3). Normocapnic, hypercapnic, and hypocapnic values of heart rate, mean arterial pressure, partial end-tidal CO2 pressure, Paco2, and Vmca were obtained.

Background: Intravenous somatostatin decreases acid secretion, splanchnic blood flow, and portal pressure, but the evidence for its efficacy in the treatment of non-variceal upper gastrointestinal bleeding has been mixed. We aimed to evaluate the vasoactive effect and possible mechanisms of somatostatin infusion in the cessation of non-variceal upper gastrointestinal bleeding.

Material/methods: Patients with non-variceal upper gastrointestinal bleeding without portal hypertension were enrolled in the study.

Objective: Varicocele can be defined as an abnormal tortuosity and dilatation of the veins of the pampiniform plexus. Contradictory results have been obtained from experimental animal models and a few clinical human studies on testicular arterial blood flow in varicocele. The purpose of this study was to determine the changes in testicular arterial blood flow parameters in patients with varicocele.

Objective: To assess musculoskeletal ultrasonographic (US) findings in patients with type 2 diabetes mellitus (DM) with and without pes anserinus (PA) tendinitis or bursitis syndrome; and to determine possible etiologic factors such as systemic diabetic microvascular disease complications in these patients.

Methods: The knee joints were examined with an ultrasound real-time scanner using a 10 MHz electronic linear transducer in 48 patients with type 2 DM and 25 controls. The presence of systemic diabetic microvascular disease complications was evaluated.
