Published: November 2009

AbstractBackgroundInvoluntary cough is a classic symptom of many respiratory diseases. The act of coughing serves a variety of functions such as clearing the airways in response to respiratory irritants or aspiration of foreign materials. It has been pointed out that a cough results in substantial stresses on the body which makes voluntary cough a useful tool in physical diagnosis.MethodsIn the present study, fifty-two normal subjects and sixty subjects with either obstructive or restrictive lung disorders were asked to perform three individual voluntary coughs. The objective of the study was to evaluate if the airflow and sound characteristics of a voluntary cough could be used to distinguish between normal subjects and subjects with lung disease. This was done by extracting a variety of features from both the cough airflow and acoustic characteristics and then using a classifier that applied a reconstruction algorithm based on principal component analysis.ResultsResults showed that the proposed method for analyzing voluntary coughs was capable of achieving an overall classification performance of 94% and 97% for identifying abnormal lung physiology in female and male subjects, respectively. An ROC analysis showed that the sensitivity and specificity of the cough parameter analysis methods were equal at 98% and 98% respectively, for the same groups of subjects.ConclusionA novel system for classifying coughs has been developed. This automated classification system is capable of accurately detecting abnormal lung function based on the combination of the airflow and acoustic properties of voluntary cough.

Published: November 2009

Abstract

Introduction
Laryngeal tuberculosis used to be a common complication in advanced pulmonary tuberculosis. However, it has become a rare occurrence in developed countries since the introduction of antituberculous agents. Moreover, the pattern of the disease has changed over the years. Nowadays, it more closely resembles a laryngeal carcinoma than any other laryngeal illness.

Case presentation
We describe the case of a 50-year-old Caucasian man who presented with the clinical picture of laryngeal cancer, but which turned out to be tuberculosis. We illustrate the difficulty of recognizing laryngeal tuberculosis both clinically and even with radiological examination.

Conclusion
Although laryngeal tuberculosis is uncommon, especially in developed countries, it still occurs and should be considered as a differential diagnosis in any laryngeal disease, in particular in the case of a laryngeal carcinoma.

Published: November 2009

Abstract

Introduction
Squamous cell carcinoma is the most common malignant tumor of the oral cavity and one of the 10th most common causes of death. It arises from dysplastic oral squamous epithelium. By considering the pathogenesis of squamous cell carcinoma, the smooth and intact surface for this lesion is not usual.

Case presentation
A painful nodular lesion with smooth surface on the left buccal mucosa of a 75-year-old female patient was observed. She noticed it 2 weeks ago. Histopathological examination revealed oral squamous cell carcinoma.

Conclusion
In this paper, we report an unusual clinical presentation of oral squamous cell carcinoma in buccal mucosa which is very rare.

Published: November 2009

Abstract
We present a 6-month-old African American male child with a chief complaint of failure to appropriately gain weight despite adequate caloric intake via breastfeeding. While he has met developmental milestones he appears small for age and is diagnosed with failure to thrive after crossing two major growth curve percentiles. After appropriate diagnostic workup, a diagnosis of nutritional vitamin D deficiency (rickets) was reached and supplementation was initiated with ensuing adequate catch-up growth.
A rare coexistence of concurrent breast hemangioma with fibroadenoma: a case report
Authors: Kawatra Vibha , Lakshmikantha Akhila , Dhingra Kajal Kiran , Gupta Parul , Khurana Nita 
Published: November 2009

Abstract
We report the case of a 38-year-old Asian, Indian female with capillary hemangioma breast in coexistence with the commonly occurring fibroadenoma. Clinical examination of the breast revealed a 4 cm diameter lump. Mammography revealed a well defined slightly hypoechoic lesion with smooth contours. A lumpectomy was performed. Histopathology confirmed the diagnosis of a completely encapsulated fibroadenoma coexistent with a capillary hemangioma in the adjacent breast tissue. The rarity of literature on breast hemangioma especially capillary type with coexisting fibroadenoma deserves mention.

Published: November 2009

Abstract
We report a young healthy woman, who believed that the consumption of large amounts of honeycomb would lead to good health and who finally developed a huge gastric bezoar of hard consistency. The conventional endoscopic techniques failed to manage the bezoar. Using the combination of injection of hydrogen peroxide 3% solution inside the bezoar to induce disintegration and a special designed needle-knife sphincterotome (bezotome) we managed to remove the bezoar in fragments. To the best of our knowledge this is the first reported bezoar caused by honeycomb.
Bilateral metachronous ovarian metastases from clear cell renal carcinoma: a case report
Authors: Albrizio Mauro , La Fianza Alfredo , Gorone Maria Sole Prevedoni 
Published: November 2009

Abstract

Introduction
Bilateral ovarian metastases from a clear cell renal carcinoma are uncommon findings and need to be differentiated from primary cancers. Diagnostic imaging and histopathological features are often inconclusive, unless they are combined.

Case presentation
A 56-year-old woman with a history of right radical nephrectomy for a renal clear cell carcinoma diagnosed 10 years earlier was referred for abdominal distension and pelvic pain. Color-Doppler US and Computer Tomography scan revealed the presence of bilateral ovarian masses with regular margins, a low resistance index and poor contrast enhancement. Immunohistochemistry showed positive epithelial membrane antigen, cytokeratin, vimentin and CD10, suggesting clear cells from the previously diagnosed kidney cancer.

Conclusion
Although bilateral metachronous ovarian metastases from clear cell renal carcinoma are a very uncommon finding, they can be considered in the differential diagnosis and investigated with imaging and immunohistochemistry. The 6 cases reported in the literature indicate a good prognosis for this condition.
Multiple intraosseous lipomatosis: a case report
Authors: Rehani Bhavya , Wissman Robert 
Published: November 2009

AbstractIntroductionIntraosseous lipoma is an uncommon entity that presents almost exclusively as a solitary lesion. Multiple intraosseous lipomas are exceedingly rare with only a few cases being reported in the literature.Case presentationWe present a case of 43-year-old African American female who presented with left leg and left wrist pain. The initial radiographs revealed well-defined radiolucent lesions in multiple bones involving the left wrist and the left lower limb. The magnetic resonance demonstrated multiple lesions, which showed high signal on the T1 and low signal on the fat suppressed T2 images. This favored the diagnosis of intraosseous lipomatosis that was confirmed by biopsy.ConclusionMultiple intraosseous lipomatosis is an uncommon but important differential for multiple radiolucent lesions on the plain radiographs. This condition can lead to pathological fractures. Magnetic resonance imaging can aid in providing an accurate diagnosis. The awareness of this condition can help the clinician in guiding the correct diagnosis and management.

Authors: Narayanan C D , Prakash Preeth , Dhanasekaran C K 
Published: November 2009

Abstract
Intramuscular hemangiomas are uncommon neoplasm's arising most frequently in the masseter and trapezius muscle. Due to it's location it is often mistaken for a parotid swelling and rarely is an accurate pre-operative diagnosis achieved clinically. The intra masseteric location also poses special problem in terms of proximity to the facial nerve and the post operative flattening following excision of the masseter muscle. A case of intramuscular hemangioma in a 17 year old girl is presented. Inadequacy of computed tomography scan and cytology in achieving a pre-operative diagnosis and also the treatment modalities are reviewed here. An estrogen receptor and progesterone receptor study has been done to verify the hormonal basis of this tumour.

Published: November 2009

Abstract
An adult Caucasian male with excruciating pains following multiple traumas was monitored, daily, over one year while managing chronic pain by self-administering quantifiable amounts of natural cannabis. Tetrahydrocannabinol, Cannabidiol, and Cannabinol were all measured in tinctures, capsules, smoke-able product plus some baked goods, prior to their administration. By allowing standardization, the subject was able to develop a daily regimen of pain management that was resistant to a battery of most patent analgesics.

Published: November 2009

Abstract
Disruption of cervical esophagogastric anastomosis after retrosternal stomach transposition remains a dangerous complication. We report a case of cervical gastric disruption after retrosternal gastric transposition in a 36-year-old man that required sternotomy for reanastomosis. After sternotomy, gastric mobilization was possible, in order to gain sufficient length for a new cervical esophagogastric anastomosis.
Hepatic iron overload, a possible consequence of treatment with imatinib mesylate: a case report
Authors: Maiti Baidehi , Setrakian Sebouh , Daw Hamed A 
Published: November 2009

Abstract
Imatinib, a tyrosine kinase inhibitor has revolutionized the therapy of Philadelphia chromosome positive chronic myeloid leukemia. Side effects of imatinib include grade 1-4 hepatotoxicity in a subset of patients. We report the case of a 46-year-old male with chronic myeloid leukemia, who developed hepatic hemosiderosis during treatment with imatinib. After ruling out the established congenital and acquired causes of hepatic hemosiderosis, we attribute this to a possible side effect of imatinib therapy. This condition was successfully treated with periodic phlebotomy thus precluding discontinuation of imatinib. To our knowledge, this is the first report of hepatic hemosiderosis most likely consequent to imatinib therapy.
Treatment of ipsilateral high energy tibial plateau and calcaneal fractures by a circular wire fixator: a case report

Published: November 2009

AbstractIntroductionHigh energy tibial plateau fractures along with calcaneal fractures individually produce several challenges for the orthopaedic surgeon. The principles of bony reconstruction include anatomic reduction and rigid internal fixation of intra-articular fractures and accurate restoration of the coronal, sagittal and transverse mechanical axes. Due to the tenuous nature of the soft tissue and devitalisation of the comminuted fragments with open reduction, external fixation of type 6 tibial plateau fractures is recommended. We report a case with ipsilateral high energy tibial plateau and calcaneal fractures both of which were managed with an ilizarov ring fixator.Case presentationA 55-year-old Kashmiri female presented to our department with an ipsilateral fracture of the tibial plateau and the calcaneum. Both were closed reduced and stabilized with an ilizarov ring fixator.ConclusionThe circular wire fixator provides a viable method to manage such fractures especially if they are co existent. This is especially true in situations where the soft tissue is compromised.

Published: November 2009

Abstract

Introduction
Although rare, rupture of an unscarred uterus is one of the most dangerous obstetric complications, resulting in maternal and fetal jeopardy.

Case presentation
A 30-year-old grand multiparous Turkish woman without any history of uterine surgery gave birth vaginally at 37 weeks of gestation with fundal pressure applied in the second stage of labor. Transabdominal sonography performed 32 hours after delivery due to postural hypotension and a drop in hemoglobin values in the postpartum period revealed massive intra-abdominal free fluid. On emergency laparotomy, serosal rupture of the uterus on the left posterior side was observed. She underwent a subtotal hysterectomy and did well postoperatively.

Conclusion
Postural hypotension in postpartum patients without any evident vaginal bleeding may be an early sign of possible uterine rupture, even if the vital signs are stable. Early diagnosis is important if maternal morbidity and mortality are to be decreased.

Abstract
Introduction
Acute post-traumatic brain swelling (BS) is one of the pathological forms that need emergent treatment following traumatic brain injury. There is controversy about the effects of craniotomy on acute post-traumatic BS. The aim of the present clinical study was to assess the efficacy of unilateral decompressive craniectomy (DC) or unilateral routine temporoparietal craniectomy on patients with unilateral acute post-traumatic BS.

Methods
Seventy-four patients of unilateral acute post-traumatic BS with midline shifting more than 5 mm were divided randomly into two groups: unilateral DC group (n = 37) and unilateral routine temporoparietal craniectomy group (control group, n = 37). The vital signs, the intracranial pressure (ICP), the Glasgow outcome scale (GOS), the mortality rate and the complications were prospectively analysed.

Results
The mean ICP values of patients in the unilateral DC group at hour 24, hour 48, hour 72 and hour 96 after injury were much lower than those of the control group (15.19 +/- 2.18 mmHg, 16.53 +/- 1.53 mmHg, 15.98 +/- 2.24 mmHg and 13.518 +/- 2.33 mmHg versus 19.95 +/- 2.24 mmHg, 18.32 +/- 1.77 mmHg, 21.05 +/- 2.23 mmHg and 17.68 +/- 1.40 mmHg, respectively). The mortality rates at 1 month after treatment were 27% in the unilateral DC group and 57% in the control group (p = 0.010). Good neurological outcome (GOS Score of 4 to 5) rates 1 year after injury for the groups were 56.8% and 32.4%, respectively (p = 0.035). The incidences of delayed intracranial hematoma and subdural effusion were 21.6% and 10.8% versus 5.4% and 0, respectively (p = 0.041 and 0.040).

Conclusions
Our data suggest that unilateral DC has superiority in lowering ICP, reducing the mortality rate and improving neurological outcomes over unilateral routine temporoparietal craniectomy. However, it increases the incidence of delayed intracranial hematomas and subdural effusion, some of which need secondary surgical intervention. These results provide information important for further large and multicenter clinical trials on the effects of DC in patients with acute post-traumatic BS.

The association between adolescents' beliefs in a just world and their attitudes to victims of bullying
Authors: Fox Claire L. , Elder Tracey. , Gater Josephine. , Johnson Elizabeth. 
Published: November 2009

BackgroundResearch which has investigated children's attitudes to bullying has found that the majority of children display anti‐bullying attitudes. However, a small minority of children do appear to admire the bully and lack sympathy for victims of bullying. The just world belief theory has received a great deal of attention in recent years with evidence emerging in support of a two‐dimensional model distinguishing between beliefs in a just world (BJW) for self and BJW for others. BJW‐self (and not BJW‐others) has been found to uniquely predict psychological well‐being, whereas BJW‐others (and not BJW‐self) uniquely predicts harsh social attitudes and derogation of victims.AimThe aim of the present study was to measure BJW‐self and others in a sample of UK secondary schoolchildren and to see whether BJW‐others can account for adolescents' negative attitudes towards victims of bullying.SampleIn total, 346 pupils aged 11–16 years of age (270 males, 76 females) from two schools took part in the study.MethodsThe participants completed measures of BJW‐self and others, attitudes to victims of bullying, empathy, and self‐esteem on a whole class basis.ResultsIt was found that BJW‐others uniquely predicted adolescents' attitudes to victims but in the opposite direction to that which was predicted – high BJW were associated with stronger anti‐bullying attitudes. As predicted, BJW‐self (but not BJW‐others) was positively and uniquely correlated with self‐esteem.ConclusionThe findings are discussed in the context of research which has found that the direction of the relationship between BJW‐others and derogation of victims appears to depend on the nature of the injustice, with people with strong BJW less tolerant of severe injustices.
Type D personality, stress, and symptoms of burnout: The influence of avoidance coping and social support

Published: November 2009

Objective. This study investigated whether approach coping, avoidance coping, or perceptions of available social support mediated the relationship between Type D personality and perceived stress. Furthermore, this research also examined whether Type D moderated the relationship between perceived stress and symptoms of burnout.Methods. In this cross‐sectional study, 334 (male N =180; female N =154) first‐year undergraduate students completed the Type D Scale‐14 (DS14), the Brief Approach/Avoidance Coping Questionnaire, Perceived Stress Scale, Multidimensional Scale of Perceived Social Support, and the Oldenburg Burnout Inventory.Design. Cross‐sectional.Results. Multiple mediation analysis revealed that only resignation and withdrawal coping, but not social support partially mediated the relationship between Type D and perceived stress. A small moderation effect was found for the disengagement subscale of the burnout inventory, with Type D individuals experiencing higher levels of disengagement at low and average stress levels. The correlations between variables provided support for most of the prediction from the literature with regard to Type D.Conclusion. Of the participants in the present study, 24.9% were classified as Type D. These individuals tend to use more passive and maladaptive avoidance coping strategies such as resignation and withdrawal. This is associated with higher levels of perceived stress and linked to increased levels of burnout symptoms
Fire Performance Testing of Building Element Interfaces and Connections
Authors: Parker Arthur J. , Iwankiw Nestor R. 
Published: November 2009

Abstract
The minimum fire-resistance ratings for vertical and horizontal assemblies and structural members are provided in the prescriptive requirements of the building codes. National and international test methods have been developed to provide a standardized means for evaluating the performance of these building elements. Building elements such as horizontal assemblies (floors), vertical assemblies (walls), and structural members (beams and columns) are generally tested as discrete elements. In an actual building, the walls intersect with the floors and beams and girders are connected to columns. In light of recent high-profile fire events, the fire community has been questioning if these connections and interfaces are being properly tested and evaluated. In an actual building, these building elements are interconnected, and their performance is affected by all elements that comprise the building structure during a real fire event. This paper will review common structural building interface and connection construction features, how they are currently being evaluated, and how their large-scale fire performance evaluations can be conducted. The results of the testing of a simulated wall/floor assembly interface assembly will be presented to highlight one potential means for testing these features along with the limitations mainly due to the available test equipment.
