Modern lifestyle and advanced technology have given life easier, but this has led to many diseases. In advanced lifestyle irregular eating habits, eating unhealthy foods and eating spicy fast food has become a fashion and alcohol consumption is increasing day by day. All of these factors lead to different disorders. Kamala is one among the diseases which are caused due to excessive intake of sour food, alcohol, unhealthy food and when a person with Panduroga continues intake of Pittakara Aahara then he may develop Kamala. According to modern science, Kamala can be correlated with Jaundice. Clinically the Jaundice is a sign of an ongoing disease process with common signs and symptoms like yellowish discolourations of the skin, mucous membranes, the eyes, urine etc. It is characterized by increase deposition of bile pigments in body fluids and tissues. It is perceptible only when the bilirubin level and its conjugates exceeds 1.5 mg/ 100ml plasma. Here is the case study of a patient who appeared to Parul Ayurved Hospital with the history of oedema over the bilateral lower limbs, heaviness in abdomen and chest region in the last 1 year, fever since 4-5 months and yellowish discolourations of eyes, nails and urine are present. In the present study, the patient was treated with Ayurvedic treatments i.e. Virechana Karma and Shamana Chikitsa.

Aim of the study To evaluate the agreement between planned and delivered doses and its potential correlation with the plans' complexity subjected to dosimetric verification. Material and methods Four isocentre volumetric modulated arc therapy for total marrow irradiation plans optimized simultaneously with (P1) and without (P2) MU reduction were evaluated dosimetrically by γ method performed in a global mode for 4 combinations of γ-index criteria (2%/2 mm, 2%/3 mm, 3%/2 mm, and 3%/3 mm). The evaluation was conducted for 4 regions (head and neck, chest, abdomen and upper pelvis, and lower pelvis and thighs) that were determined geometrically by the isocentres. The Wilcoxon test was used to detect significant differences between γ passing rate (GPR) analysis results for the P1 and P2 plans. The Pearson correlation was used to check the relationship between GPR and the plans' complexity. Results Except for the head and neck region, the P2 plans had better GPRs than the P1 plans. Only for hard combinations of γ-index criteria (i.e. 2%/3 mm, 2%/2 mm) were the GPRs differences between P1 and P2 clinically meaningful, and they were detected in the chest, abdomen and upper pelvis, and lower pelvis and thighs regions. The highest correlations between GPR and the indices describing the plans' complexity were found for the chest region. No correlation was found for the head and neck region. Conclusions The P2 plans showed better agreement between planned and delivered doses compared to the P1 plans. The GPR and the plans' complexity depend on the anatomy region and are most important for the chest region.

Summary Deep brain stimulators (DBSs) are sometimes used to treat refractory movement disorders such as Parkinson's disease. When DBSs are implanted in a subcutaneous pocket in the chest region, breast reconstruction becomes a challenge because monopolar electrocautery can lead to DBS dysfunction or brain tissue damage caused by heat. We report a patient with a DBS who underwent one-stage implant-based breast reconstruction. We switched off the DBS before surgery and used monopolar electromagnetic cautery with minimum power settings to undermine the subcutaneous pocket for the breast implant. The DBS was switched back on immediately after completion of the surgery. The patient's postoperative recovery was uneventful with the DBS fully functional.

Computed tomography (CT) is commonly associated with relatively high patient doses. In order to keep the patient doses from the CT examinations on the acceptable level it is necessary to apply the principle of optimization. An essential part of optimization is the achievement of the compromise between the patient dose reduction and the maintenance of the image quality that provides accurate diagnostic information. The aim of the study was to determine the relations between the patient doses, CT image quality and the parameters of the tube current modulation program (Auto mA, CareDose and DoseRight) for the examination of the chest. The study was performed on the three most common modern tomographs in Russia: Ingenuity Core 128, Philips; Optima 64, General Electric; Definition AS, Siemens. The anthropomorphic phantom Lungman (Kyoto Kagaku CO., LTD) was used in the study. In order to assess the tube current modulation for the range of tube voltage (80–120 kV), the reference mA∙s (ref. mAs), Noise Index (NI) and Dose Right Index (DRI) were changed for the CareDose (Siemens), Auto mA (GE) and RightDose (Philips), respectively. Estimation of the effective dose was performed using the method from Methodical guidance 2.6.1.2944-11 (MU 2.6.1.2944-11). In order to evaluate the image quality, the noise of a CT image in the mediastinum was selected as the most homogenous for chest region. It was estimated, that for the GE units with Auto mA, the noise of CT image had a liner relationship with NI; the patient dose decreased with the increase of NI. For the Siemens units with CareDose, the noise of CT image decreased with the ref.mAs for the range of tube voltage (80–120 kV); the patient dose was directly proportional to the ref.mAs and increased with the tube voltage. For the Philips units with DoseRight, the noise of CT image decreased with the DRI for the range of tube voltage (80–120 kV); the patient dose was directly proportional to the DRI and had no dependence on the tube voltage. The tube current modulations are proprietary for each manufacturer; it is necessary to consider them for the protocol development. The obtained dependences could be useful for optimization of CT protocols.

Purpose The aim of this study is to propose an algorithm for the automated calculation of water‐equivalent diameter (Dw) and size‐specific dose estimation (SSDE) from clinical computed tomography (CT) images containing one or more substantial body part. Methods All CT datasets were retrospectively acquired by the Toshiba Aquilion 128 CT scanner. The proposed algorithm consisted of a contouring stage for the Dw calculation, carried out by taking the six largest objects in the cross‐sectional image of the patient's body, followed by the removal of the CT table depending on the center position (y‐axis) of each object. Validation of the proposed algorithm used images of patients who had undergone chest examination with both arms raised up, one arm placed down and both arms placed down, images of the pelvic region consisting of one substantial object, and images of the lower extremities consisting of two separated areas. Results The proposed algorithm gave the same results for Dw and SSDE as the previous algorithm when images consisted of one substantial body part. However, when images consisted of more than one substantial body part, the new algorithm was able to detect all parts of the patient within the image. The Dw values from the proposed algorithm were 9.5%, 15.4%, and 39.6% greater than the previous algorithm for the chest region with one arm placed down, both arms placed down, and images with two legs, respectively. The SSDE values from the proposed algorithm were 8.2%, 11.2%, and 20.6% lower than the previous algorithm for the same images, respectively. Conclusions We have presented an improved algorithm for automated calculation of Dw and SSDE. The proposed algorithm is more general and gives accurate results for both Dw and SSDE whether the CT images contain one or more than one substantial body part.

The application of segmentation methods to medical imaging has the potential to create novel diagnostic support models. With respect to fetal ultrasound, the thoracic wall is a key structure on the assessment of the chest region for examiners to recognize the relative orientation and size of structures inside the thorax, which are critical components in neonatal prognosis. In this study, to improve the segmentation performance of the thoracic wall in fetal ultrasound videos, we proposed a novel model-agnostic method using deep learning techniques: the Multi-Frame + Cylinder method (MFCY). The Multi-frame method (MF) uses time-series information of ultrasound videos, and the Cylinder method (CY) utilizes the shape of the thoracic wall. To evaluate the achieved improvement, we performed segmentation using five-fold cross-validation on 538 ultrasound frames in the four-chamber view (4CV) of 256 normal cases using U-net and DeepLabv3+. MFCY increased the mean values of the intersection over union (IoU) of thoracic wall segmentation from 0.448 to 0.493 for U-net and from 0.417 to 0.470 for DeepLabv3+. These results demonstrated that MFCY improved the segmentation performance of the thoracic wall in fetal ultrasound videos without altering the network structure. MFCY is expected to facilitate the development of diagnostic support models in fetal ultrasound by providing further accurate segmentation of the thoracic wall.

Image in medicine Five (5) years old male patient came to outpatient department with complain of multiple swelling over chest region with upper extremities. The clinical examination revealed that there is chest multiple mass growth of about 3-4 cm bilaterally each over chest, upper extremities and forehead. The development of multiple benign osteocartilaginous masses (exostoses) begins with the relation with the ends of long bones of the lower limbs such as the femurs and tibias and of the upper limbs such as the humerus and forearm bones with chest region. The patient also had complains of difficulty in eating, finger grips, as well as loss of functional independence. On clinical examination the patient was diagnosed with a rare case of hereditary multiple osteochondromas (HMO).

Objectives: This study aims to first measure patient doses during computed tomography (CT) chest, abdomen, and extremities procedures for evaluation lymphedema, and second to estimate the radiation dose-related risks during the procedures. Material and Methods: Radiation effective doses from CT lymphography procedures quantified using CT machines from different vendors. After the calibration of CT systems, the data collected for a total of 28 CT lymphography procedures. Effective and organ doses extrapolated using national radiological protection software based on Monte Carlo simulation. Results: The mean patient doses for chest and abdomen procedures in term of CTDIvol (mGy) and DLP (mGy.cm) are 10.0 ± 3 and 425 ± 222 and 24 ± 12 and 1118 ± 812 for CT 128 and CT 16 slice, respectively. The mean DLP (mGy.cm) for extremities was 320 ± 140 and 424 ± 212 for CT 128 and CT 16 slice, in that order. Conclusion: Patients’ dose showed significant differences due to variation in the scan length and clinical indication. Organs lay in the primary beam received high radiation doses especially in the chest region which increases the probability of radiation-induced cancer. The current patient’s doses are higher compared to the previous studies.

Developmental changes in the body proportions of western North Pacific Bryde’s whales (Balaenoptera edeni) were investigated by examining the proportion of each body part to the total body length. The head and chest region increased to a certain body length; subsequently, the length of head region stabilized, and that of the chest region decreased. The length of the abdominal region remained constant to a certain body length and subsequently showed a marked increase, and that of the tail region decreased consistently. The length of dorsal fin and flukes decreased consistently, whereas that of the flippers remained constant to a certain body length and subsequently decreased. The relative growth pattern determined by an allometric analysis was positive for the head region but negative for the lower body part, flippers, flukes, and dorsal fin. Both sexes demonstrated the same growth pattern, but the coefficients differed. This is the first study to investigate developmental changes in the body proportions of Bryde’s whales using more than 700 specimens covering a wide body length range. We believe that the results of this study will contribute to various research fields, including taxonomy, phylogeny, and feeding ecology of this species.

An important step for computerized analysis of breast magnetic resonance imaging (MRI) is segmentation of the breast region. Due to the similar signal intensity of fibroglandular tissue and the chest wall, the segmentation process is difficult for breasts with fibroglandular tissue connected to the chest wall. In order to overcome this challenge, a new framework is presented that relies on a chest region atlas. The proposed method first detects the approximated breast-chest wall boundary using an intensity-based operation. A support vector machine (SVM) then determines the connectivity of fibroglandular tissue to the chest wall by the extracted features from the obtained breast-chest wall boundary. Finally, the obtained breast-chest wall boundary is accurately refined using the geometric shape of the chest region, which is obtained by an atlas-based segmentation method. The proposed method is validated using a dataset of 5964 breast MRI images from 126 women. The Dice similarity coefficient (DSC), total overlap (TO), false negative (FN), and false positive (FP) values are calculated to measure the similarity between automatic and manual segmentation results. Our method achieves DSC, TO, FN, and FP values of 96.46%, 96.41%, 3.59%, and 3.51%, respectively. The results prove the effectiveness of the presented algorithm for breasts with different sizes, shapes, and density patterns.

Automatic lung segmentation is an essential step towards the Computer-Aided Diagnosis of the lung CT scan. However, in presence of dense abnormalities, existing methods fail in accurate lung segmentation. In this paper, a generative adversarial networks-based approach is proposed for improving the accuracy of lung segmentation. The proposed network effectively segments the lung region from the surrounding chest region hence, named as LungSeg-Net. In the proposed LungSeg-Net, the input lung CT slices are processed through the trail of encoders which encode these slices into a set of feature maps. Further, a multi-scale dense-feature extraction (MSDFE) module is designed for extraction of multi-scale features from the set of encoded feature maps. Finally, the decoders are employed to obtain the lung segmentation map from the multi-scale features. The MSDFE makes the network to learn the relevant features of dense abnormalities whereas the iterative down-sampling followed by the up-sampling makes it invariant to the size of the dense abnormality. The publicly available benchmark ILD dataset is used for the experimental analysis. The qualitative and quantitative analysis has been carried out to compare the performance of the proposed network with the existing state-of-the-art methods for lung segmentation. The experimental analysis show that the performance of the proposed LungSeg-Net is invariant to the presence of dense abnormalities in lung CT scan.

A 70-year-old female patient presenting with swelling and subcutaneous nodule formation localized to the knee scars over a two-month period is presently reported. Dermatological examinations found erythematous swelling and small papules on the patient's knee scars, along with subcutaneous nodules beneath and around the scars. Computer tomography of the chest region identified multiple obscure tubercles in the lungs and swollen lymph nodes in the hilum pulmonis and mediastinum. Skin biopsy revealed multiple non-caseating granulomas, which had infiltrated the dermis. The patient was diagnosed with scar sarcoidosis as a result of these observations. The onset of scar sarcoidosis is rare and, therefore, not well understood; however, inflammatory alterations in preexisting scars may be important indicators for disease onset.

1706 Objectives: 90Y-radioembolization treatment planning includes determination of the lung shunt fraction (LSF) to maintain mean lung dose to below 25-30 Gy. The estimated mean lung dose constrains the total amount of administered activity and hence the ability to treat tumor to higher dose levels. The device package inserts recommend use of 1000 g lung mass in the calculation of lung dose. Errors in lung mass and lung shunt fraction contributes to the overall errors in lung doses. Here we investigated the accuracy and 95% prediction interval (95%PI) of 5 common methods for calculating the lung mass. The bias can be corrected, if errors are normally distributed, rendering the 95%PI as the more relevant metric. As secondary objective, we investigated the mean errors in lung mass and lung dose that stems from using a fixed 1000 g lung mass for all patients. Relative errors in lung mass estimation are directly proportional to the errors in lung dose. Methods: An IRB-approved retrospective study was conducted on 52 consecutive HCC patients assessed for 90Y-radioembolization with TheraSphere from 2015-2016. As part of routine workup, all patients underwent a diagnostic contrast CT (cCT) of the chest and abdomen prior to the 99mTc-MAA SPECT and non-contrast CT (ncCT) of the liver and chest region. Of these 52 patients, 12 had complete lungs in the SPECT/ncCT field of view (FOV) while 40 had a varying range of lung in the SPECT/ncCT FOV. The gold-standard estimate of true lung mass was defined as the mean of the masses estimated from the cCT and the ncCT using an HU-based volume&density calculation. Linear regression was derived from the complete lung scan data to estimate true lung mass from a lung mass estimated using the cCT HU-based volume&density Methods: This regression was then used on all 52 patients to calculate the true lung mass from the cCT HU-based volume&density mass estimation. The 5 common methods of lung mass calculation investigated were: 1) ncCT HU-based volume&density, 2) ncCT volume & fixed 0.3 g/ml density, 3) fixed mass of 1000 g, 4) gender-based fixed mass of 1000 g for men and 800 g for women, and 5) weight-scaled gender-based fixed mass. A Bland-Altman analysis was performed to estimate the mean relative error and 95%PI of these 5 methods compared to the true lung mass. Results: The mean relative error [95%PI] for lung mass was -9% [±21%] and -11% [±23%] with the ncCT HU-based volumed the errors changed to -23% [±24%] and -14% [±33%], respectively, when partial lung was scanned. In all 52 cases, the fixed mass based methods (1000 g, gender-based, weight-scaled-gender) had large mean errors (26%, 20%, 37%) and very wide 95%PI (±44%, ±41%, ±54%). The errors were not normally distributed in the 1000 g and gender-based fixed mass methods. The 95%PI after bias corrections for all patients were 26%, 31%, and 54% for ncCT HU-based volume&density, ncCT volume&fixed-density, and weight-scaled-gender fixed mass methods. On average, the fixed lung mass of 1000 g overestimated the true lung mass by 23% [±44%] resulting in a corresponding underestimation of the lung dose. Conclusion: Use of the default fixed lung mass of 1000 g severely overestimates the true lung mass. Errors in both ncCT-based methods were lowest compared to fixed mass methods but HU-based volume&density had the narrowest 95%PI. Over all patients, lung mass errors in 95%PI after bias correction with the ncCT HU-based volume&density and volume&fixed-density methods were 26% and 31%. We recommend scanning the maximum lung volume allowed in 99mTc-MAA SPECT/CT and using the bias-corrected ncCT HU-based volume&density method to estimate lung mass when calculating mean lung dose for 90Y-radioembolization treatment planning. Investigations on incorporation of additional errors from LSF estimation on the final mean lung dose is currently underway.

Objective: The aim of this study was to evaluate the complementary and alternative medicine (CAM) methods, the prevalence of their use, and to assess the factors that influence using these methods in children with asthma and/or allergic rhinitis in Van. Material and Methods: The study was conducted between June 2015 and January 2016. A survey form consisting of 15 questions was prepared. These questions were posed to the parents of the children with asthma and/or allergic rhinitis who were being followed-up at the pediatric allergy and immunology outpatient clinic. Results: The study included 127 parents of children aged 2-17 years. The mean age of the patients was 7.9 ± 3.6 years. 62 (48.8%) of the 127 parents stated that they had used CAM methods at any time of their life. 9 (14.5%) of the CAM users thought that they had benefited from these methods. The most common modality was molasses used in 45 (72.5%) of the patients. 44 (70%) of the patients used herbs and spices (linden, rosehip, mountain thyme, black pepper, cinnamon, etc.), 23 (37%) used honey, 13 (20%) used quail eggs, 10 (16.1%) used olive oil, 6 (9.6%) used cow’s milk, 1 (1.6%) used bee milk, 1 (1.6%) used bee pollen and 1 (1.6%) used Vicks application to the chest region. Most of the parents had accessed information about CAM methods through a herbalist and the media. Conclusion: In conclusion, the prevalence of reported CAM use among patients with diagnosed asthma and/or allergic rhinitis in Van was found to be high (48.8%) and at a similar rate with other regions of our country, with molasses (72.5%) being the most popular modality. The pediatric allergy specialist should have knowledge about these methods and inform parents about their possible side effects.

Localized scleroderma in the chest region of adolescent girls leads to incomplete breast development and breast asymmetry, for which patients may require treatment. The site of localized scleroderma, its activity, the surgeon, and the patient's desires influence the selection of treatment method. There have been few reports on surgical treatment of this disease. In the current report, we present a case in which improved breast asymmetry was achieved through multiphased surgery, and we review treatment methods and indications of this disease. Level of Evidence: 5 ![Graphic][1] [1]: /embed/inline-graphic-1.gif

This study presents comparison results between axial and spiral scanning in the head and chest region with 64 MDCT to evaluate organ doses in infants and toddlers, who ar e more radiosensitive to radiation than adults and rise in the number of CT examinations, during CT scanning. Organ doses were significantly lower in spiral scanning than axial scanning regardless of scanned regions. The average organ dose for the chest scan using pitch of 1.355 was found to be significantly higher(average -12 .03%) than for the other two pitch settings(0.525 and 0.988) in the spiral scanning mode compared with the axial one. Organ doses in the spiral scanning mode were lower by average 20.54% than the axial scann ing mode. The results of the study that evaluated organ doses with an anthropomorphic phantom will help to demonstrate the result values of Monte Carlo simulations and make a contribution to more accurate eval uations of organ doses in toddlers undergoing a CT examination. Key Words : Infants and Toddlers, Axial Scan, Spiral Scan, Organ dose, demonstrate

Objectives This study aimed to measure the absorbed doses in selected organs for prospectively ECG-triggered coronary computed tomography angiography (CCTA) using five different generations CT scanners in a female adult anthropomorphic phantom and to estimate the effective dose (HE). Materials and Methods Prospectively ECG-triggered CCTA was performed using five commercially available CT scanners: 64-detector-row single source CT (SSCT), 2 × 32-detector-row-dual source CT (DSCT), 2 × 64-detector-row DSCT and 320-detector-row SSCT scanners. Absorbed doses were measured in 34 organs using pre-calibrated optically stimulated luminescence dosimeters (OSLDs) placed inside a standard female adult anthropomorphic phantom. HE was calculated from the measured organ doses and compared to the HE derived from the air kerma-length product (PKL) using the conversion coefficient of 0.014 mSv∙mGy-1∙cm-1 for the chest region. Results Both breasts and lungs received the highest radiation dose during CCTA examination. The highest HE was received from 2 × 32-detector-row DSCT scanner (6.06 ± 0.72 mSv), followed by 64-detector-row SSCT (5.60 ± 0.68 and 5.02 ± 0.73 mSv), 2 × 64-detector-row DSCT (1.88 ± 0.25 mSv) and 320-detector-row SSCT (1.34 ± 0.48 mSv) scanners. HE calculated from the measured organ doses were about 38 to 53% higher than the HE derived from the PKL-to-HE conversion factor. Conclusion The radiation doses received from a prospectively ECG-triggered CCTA are relatively small and are depending on the scanner technology and imaging protocols. HE as low as 1.34 and 1.88 mSv can be achieved in prospectively ECG-triggered CCTA using 320-detector-row SSCT and 2 × 64-detector-row DSCT scanners.

Considerable number of women are enjoying swimming, however, the chest-region of swimsuits including cup inserts are not stable during swimming. The purpose of this study was to explore alternate designs and methods of stabilizing the breast cup to the swimmer's body by using 3D technology to design and position the pad and cup pattern of the swimming suit. To position the pad optimally, a 3D pattern of a nude woman was divided into blocks and different reduction rates were applied to blocks around the outlines of the breast. Two types of 3D patterns were developed. The first, referred to as the 'basic 3D pattern' provided for the curved surface of the breast point to be maintained with the remaining slack distributed evenly along the neckline, armhole and side seam. The second, referred to as the '1/3 shoulder moved 3D pattern' ignored the curved nature of the breast point by overlapping, with the resulting position of the shoulder strip moved toward the center. Three women of corresponding size and body shape evaluated the two 3D pattern designs as well as the conventional 2D pattern style of swimsuit. Respondents rated the'the basic 3D pattern' design highest in terms of stability and easy of movement in the chest region.

With development of endoscopic surgery and medical robotics, surgery using endoscope robots has become a representative of robotic surgery. This chapter describes classification, design methods and evaluation methods of endoscope robots. Expectations for a minimally invasive surgery have increased year by year with the dramatic advancement of image diagnosis technology, including CT and MRI. A camera (endoscope) and surgical instruments are inserted into tiny holes made in the patients’ abdomen or chest region for surgical procedures. Compared to abdominal or open chest surgery, endoscopic surgery has less pain and has a greater advantage in cosmetic appearance as well as the economic advantages, resulting in its growing popularity. The most distinctive feature of endoscopic surgery is that the surgical field is observed through images taken by an endoscope, rather than the naked eye. The most important element to surgical safety and efficient operating is how well an endoscope reveals the field of view during surgery. Generally, a camera assistant operates the endoscope. The operation of the endoscope needs fine adjustment for the angle of the field of view and the distance of the surgical area as well as correct aiming of the endoscope at the surgical field. Camera assistants sometimes operate the endoscope according to instructions of a surgeon; however, camera assistants need to operate the endoscope using their judgment in understanding the surgeon’s intentions so that they can move the endoscope according to how the surgery is progressing moment to moment. The operation of an endoscope by camera assistants requires as much proficiency as that of surgeons. There are not many surgeons who have sufficient proficiency in endoscopic surgery, which requires special techniques. In fact, it is not unusual for surgery to be interrupted due to a camera assistant not being sufficiently proficient in using the endoscope and is unable to obtain the exact field of surgery required. To solve this problem, "endoscope robots that can hold and position an endoscope instead of a human camera assistant" (Fig. 1) have been developed. Fig. 1(a) shows a usual endoscopic

Eight male Japanese Brazilians (20-32 yrs) and 11 male Japanese (22-24 yrs) volunteered for this study. The Brazilians had been staying for about 2-21 weeks in Japan. Their physical characteristics are not significantly different from those of the Japanese. Each one of them sat on a chair for 45 min at 40 degrees C (R.H. 50%) in a climatic chamber. Then, they exercised using a bicycle ergometer in a semi-reclining position for 45 min at 40% of maximal oxygen uptake. Forearm blood flow (FBF), oxygen uptake (VO2), heart rate (HR), skin temperature (Tsk), sweat rate (SR) at chest region and body weight loss (delta Wt) were measured. Thermal sensation and thermal comfort were also measured. Thermal and comfort sensation confirmed that Japanese Brazilians felt cooler and more comfortable in 40 degrees C environment than the Japanese. VO2, SR and delta Wt for both groups were not significantly different. FBF and HR for Brazilians were significantly lower than those for Japanese. Tsk at chest region for Brazilians was found to be significantly higher than that for Japanese. Thus the thermoregulatory responses observed in Japanese Brazilians may be largely attributed to the climate in their native places located on the Tropic of Capricorn.

Computerized tomography scans of a ferruginous concretion within the chest region of an ornithischian dinosaur reveal structures that are suggestive of a four-chambered heart and a single systemic aorta. The apparently derived condition of the cardiovascular system in turn suggests the existence of intermediate-to-high metabolic rates among dinosaurs.

Key Clinical Message A 55-year-old man of dark complexion presented with multiple extensive swellings over the chest, right upper arm, and left shoulder for 10 years. Swellings were hyperpigmented, firm, and intensely pruritic especially over the chest region. The swellings progressed in size, extended, and developed satellite lesions over its 10 years history.

A 71-year-old lady was referred by her general practitioner to an orthopaedic clinic for management of shoulder pain. The patient complained of pain in the shoulder and chest region but also described reduced sensation and power in her arm and a worsening of her respiratory symptoms. These prompted further investigation with an isotope bone scan which showed a large soft tissue mass posteriorly in the apex of the right lung with chest wall extension and destruction of adjacent ribs. A subsequent CT scan identified Pancoast's tumour. This case highlights the importance of considering non-musculoskeletal causes of shoulder region pain.

Experimental studies have shown that a pneumothorax (collapsed lung) substantially alters the propagation of sound introduced at the mouth of an intubated subject and measured at the chest surface. Thus, it is hypothesized that an inexpensive diagnostic procedure could be developed for detection of a pneumothorax based on a simple acoustic test. In the present study, theoretical models of sound transmission through the pulmonary system and chest region are reviewed in the context of their ability to predict acoustic changes caused by a pneumothorax, as well as other pathologic conditions. Such models could aid in parametric design studies to develop acoustic means of diagnosing pneumothorax and other lung pathologies. Extensions of previously developed simple models of the authors are presented that are in more quantitative agreement with experimental results and that simulate both transmission from the bronchial airways to the chest wall, as well as reflection in the bronchial airways.

Traumatic pulmonary pseudocyst (TPP) is a rare complication following blunt trauma. We report a 26-year-old male patient who presented to the emergency room with internal bleeding and shock. Huge TPP (14 cm in diameter) was seen on whole-body computed tomography scan and complicated with bronchial bleeding. He deteriorated to respiratory failure soon after arriving at the emergency room. TPPs imply high-energy impact on the chest region and frequently complicated with pulmonary contusions, hemo- and pneumo-thorax, multiple rib fractures, flail chest, and concurrent with abdominal injuries. Emergency physicians should be aware of such rare entity and manage correctly.

A software system, CTIP, written in Fortran is discussed which remaps the computerized tomography (CT) image gray level so that both the lung and heart regions are clearly visible with a "natural anatomical appearance." The system is adaptive to image statistics derived from the gray-level histogram of the entire image. Unprocessed, conventional remap, and processed images were compared by 22 radiologists, with 82 percent preferring the processed images. All of the respondents agreed that the processed images possessed a "more anatomical" appearance than the conventional remapping approach.

Impact energy values required to cause death of anesthetized furbearers by blows delivered to the neck or chest region were determined as an aid to the development of "humane" traps. Thresh- old values for neck blows were 575 cm kg for raccoors (Procyon lotor), 430 cm kg for mink (Mustela vison) 58-63 cm kg for muskrats (Ondatra zibetTicus), and 805 cm kg for beavers (Castor canadensis). The threshold values for chest blows were 1,150, 520, 155, and 780 cm kg for raccoons, mink, muskrats, and beavers, respectively. Autopsy indicated severe internal damage occurred in all species well below threshold levels. EEGs and ECGs were taken. ECGs were not good indicators of terminal damage for beavers and muskrats, because the heart continued to beat beyond 10 minutes for most animals that could be considered clinically dead. Pelt damage occurred in muskrats at energy levels only 30 percent above threshold. J. WILDL. MANAGE. 40(4):669-676 Controversy regarding the humaneness of current trapping methods for furbearing animals has prompted government agencies, trapper associations, and private agencies to seek alternatives to existing methodology. The Humane Trap Development Commit- tee (HTDC) of the Canadian Federation of Humane Societies, in 1970, undertook a pro- gram designed to "alleviate unnecessary suffering of furbearers." The program was to achieve this objective "through the de- velopment of modern and humane traps to serve as efficient and preferred replace- ments to present inhumane methods." One portion of this study concerned the mechanical aspects of various spring impact traps. Energy output, speed of closure, and clamping force values already have been established for a variety of traps (Tschoepe
