BACKGROUND: The antenatal diagnosis of a combined esophageal atresia without tracheoesophageal fistula and duodenal atresia with or without gastric perforation is a rare occurrence. These diagnoses are difficult and can be suspected on ultrasound by nonspecific findings including a small stomach and polyhydramnios. Fetal magnetic resonance imaging adds significant anatomical detail and can aid in the diagnosis of these complicated cases. Upon an extensive literature review, there are no reports documenting these combined findings in a twin pregnancy...

Cervical chylomas are rare pseudocystic collections that lack an epithelial lining and arise from the thoracic duct or its tributaries; although they typically develop after neck surgery or trauma, they can arise from unknown causes. Treatment options include not only conservative therapy, such as dietary modification, repeated aspirations, and sclerotherapy, but also include surgical excision. We describe a case of a chyloma in a 64-year-old Japanese woman with squamous cell carcinoma of the gingiva. The chyloma developed following left segmental mandibulectomy with radical neck dissection and reconstruction, using a titanium plate and a pectoralis major myocutaneous flap...

The purposes of this study were to assess the prevalence, malignancy rate, and characteristics of incidental thyroid nodules (ITNs), and to identify factors that contribute the additional workup by ultrasound.The medical records and imaging features of ITNs reported via thoracic computed tomography (CT) were retrospectively reviewed to determine the size, multiplicity, attenuation, shape, and presence of calcification. To identify the factors associated with additional workup, we compared the workup and non-workup groups in terms of nodule characteristics, indications, and CT slices...

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a severe congenital anomaly. The observed to expected lung area-to-head circumference ratio (o/e-LHR) has been shown to provide a useful prediction of subsequent survival in fetuses with CDH in reference centers with expertise and a large caseload. However, the accuracy of o/e-LHR measurements in unselected fetal medicine units or in centers with less expertise is not well known. OBJECTIVE: To evaluate o/e-LHR measurement in prognostic evaluation of postnatal survival when the measurement is performed in fetal medicine units with different levels of expertise...

Purpose Lung Ultrasound Score (LUSS) is a useful tool for lung aeration assessment but presents two theoretical limitations. First, standard LUSS is based on longitudinal scan and detection of number/coalescence of B lines. In the longitudinal scan pleura visualization is limited by intercostal space width. Moreover, coalescence of B lines to define severe loss of aeration is not suitable for non-homogeneous lung pathologies where focal coalescence is possible. We therefore compared longitudinal vs. transversal scan and also cLUSS (standard coalescence-based LUSS) vs...

We placed a superficial serratus anterior plane catheter in an elderly woman with dementia and elevated clotting times who presented with multiple rib fractures after a mechanical fall. She was not a surgical candidate, and treatment consisted of conservative management with physical therapy and pain control. She was not a candidate for a patient-controlled analgesia regimen because of her dementia. Given her elevated international normalized ratio, thoracic epidural and paravertebral analgesia was also contraindicated...

BACKGROUND: The spread of injectate resulting from a transmuscular quadratus lumborum (TQL) block and a transverse oblique paramedian (TOP) TQL block has never been examined. The aim of this cadaveric study was to investigate by which pathway the injectate spreads cephalad into the thoracic paravertebral space and which nerves were dyed by the injectate cephalad and caudad to the diaphragm when performing a TQL and a TOP TQL block. We also aimed to investigate whether the thoracic and lumbar sympathetic trunks as well as the lumbar plexus were covered by the injectate...

Postoperative pain after bariatric surgery can be significant and yet difficult to manage. These patients frequently have associated obstructive sleep apnea and are at risk of respiratory depression with opioid analgesia. Abdominal wall blocks such as the subcostal transversus abdominis plane block are not of significant benefit, probably in part because they provide only somatic analgesia. The ultrasound-guided erector spinae plane (ESP) block is a recently described regional anesthetic technique for providing thoracic analgesia when performed at the level of the T5 transverse process...

INTRODUCTION: Palpation of a thoracic rib is a common method for reducing the risk of pneumothorax during electromyographic examination of the rhomboid major muscle, but its accuracy is unknown. METHODS: Two physicians palpated healthy subjects to attempt to identify the center of a rib located beneath the rhomboid major muscle. The identified location was examined with ultrasonography to examine its accuracy and the subject's anatomical depths. RESULTS: Forty-four subjects (88 ribs) were studied...

Pneumonia is a disease which causes high mortality in children under five years old, particularly in developing countries. This paper proposes a novel application of ultrasound video analysis for the detection of pneumonia. This application is based on the processing of small video chunks, in which an image processing algorithm analyzes each frame to get some overall video statistics. Then, based on these quantities, the likeness of presence of pneumonia in the video is determined. The algorithm exploits different geometrical properties of typical anatomical and pathological features that commonly appear in lung sonography and which are already clinically typified in the literature...

BACKGROUND: Myxofibrosarcoma is an aggressive soft tissue neoplasm, classified as a variant of malignant fibrous histiocytoma. Most often, it occurs in middle to late adult life peaking in the seventh decade and involving the lower extremities (77%), trunk (12%), and retroperitoneum or mediastinum (8%). We report the first case of thoracic myxofibrosarcoma presenting as a Pancoast tumor. CASE PRESENTATION: A 48-year-old non-tobacco smoking African-American man presented with a slow-growing mass in his neck along with 11 kg weight loss over 9 months...

Small volume pneumothorax can be challenging to diagnose in horses. The current standard method for diagnosis is standing thoracic radiography. We hypothesized that thoracic ultrasonography would be more sensitive. Objectives of this prospective, experimental study were to describe a thoracic ultrasound method for detection of small volume pneumothorax in horses and to compare results of radiography and ultrasound in a sample of horses with induced small volume pneumothorax. Six mature healthy horses were recruited for this study...

BACKGROUND AND OBJECTIVES: Thoracic epidural anesthesia is a technically challenging procedure with a high failure rate of 24% to 32% nationwide. Residents in anesthesiology have limited opportunities to practice this technique adequately, and there are no training tools available for this purpose. Our objective was to build a low-cost patient-specific thoracic epidural training model. METHODS: We obtained thoracic computed tomography scan data from patients with normal and kyphotic spine...

Venous thoracic outlet syndrome (vTOS) usually results from compression of the subclavian vein classically as a result of narrowing of the costoclavicular space. We report two rare cases of soft tissue neoplasms resulting in apparent vTOS. The first case is a 46-year old female with a two-year history intermittent unilateral shoulder pain, who was initially diagnosed with intervertebral disk herniation. Cervical fusion was performed, however her symptoms progressed and she additionally developed paresthesias and venous congestion...

The ultrasound-guided erector spinae plane (ESP) block is a newly described technique for providing thoracic analgesia. It is simple to perform and relatively noninvasive compared with thoracic epidural analgesia. In addition, the anatomy lends itself well to catheter insertion for continuous blockade. In this report, we describe the use of the ESP block as a rescue analgesic technique for postthoracotomy analgesia in a patient with failed thoracic epidural analgesia.

The ventricle peritoneal (VP) shunt is commonly used in the treatment of hydrocephalus. It is a relatively simple and effective technique, but around 70% of the patients with a VP shunt have a complication in their lifetime. Most of these complications are due to infection or mechanical dysfunction. The thoracic complications are rare. The present case is one of the small number of them found in the literature, describing hydrothorax as a complication of a VP shunt without catheter migration and without ascites...
