Objective: To describe the clinical presentation, underlying diseases, antimicrobial susceptibility, treatment and outcome of Klebsiella pneumoniae meningitis patients. Methods:This retrospective study involved all patients with 15 years of age or older who admitted to Hamad General Hospital with culture proven Klebsiella pneumoniae meningitis from January 1, 2007 to December 31, 2012. Results: A total of ten cases were identified (nine males and one female). Their mean age was (43.3±12.8) years. Eight patients (80%) had nosocomial meningitis with neurosurgery being the most frequent associated condition. Fever and altered consciousness were the most frequent symptom. Cerebrospinal fluid showed elevated protein and glucose levels. Gram stain showed Gram-negative rods in 50%of cases, while positive cerebrospinal fluid culture results were found in all patients. Multidrug resistance was observed in two cases, and all patients had received appropriate empirical and definitive antibiotic treatments. The mean duration of intravenous antimicrobial treatment was (19.3±7.0) d and all patients with external ventricular drains underwent removal of the device, while in-hospital mortality was 50%. Conclusions: The number of cases was too small to come up with therapeutic and prognostic conclusions. Further large-scale prospective study is needed.

Six hundred and ninety nine cases of alleged rape were studied by the authors during the period from 2007-2008 at the Mymensingh Medical College, Mymensingh. Of these cases, 122 had positive findings of recent sexual intercourse; 250 cases had the positive findings of habituated sexual intercourse, and 327 cases had no findings of sexual intercourse but they complained of forcible sexual intercourse and found no sign of sexual intercourse. Most of the alleged victims of rape were nulliparous 87.12% and parous was only 12.87%. 430 (61.51%) cases of reported victims who were students of schools and colleges were not considered as rape cases considering their victim's history of love affairs, leaving home secretly with their lovers, living with them for many days. Gang rape was not so common (4.29% of raped cases) in our study. Age groups, their occupations, living areas, time of arrival for medico-legal examination have been studied. Most of the cases were students (61.51%). A few numbers of victims were subjected to gang rape. Examination and reporting the cases have been discussed.

To describe ultrasonographic findings of ovarian granulosa cell tumor (GCT) and to determine their possible value in the differential diagnosis of ovarian tumors. Sonographic appearances of ten cases of pathologically proven GC Ts were retrospectively reviewed regarding their location, size, outer margin, the echo pattern of the tumor, endometrial thickness, presence of ascites, and metastasis to adjacent tissue or distant sites. 3.0-3.5 MHz trans-abdominal US or 5.0-6.5 MHz transvaginal US were used. The sonographic features could be classified as follows: unilocular cystic mass without nodule or septation (type 1), multilocular cystic mass (type 2), and solid mass (type 3). Pathologically nine cases were adult type granulosa cell tumors (GCT) and one was a juvenile type. All cases were unilateral. GCT arising from left ovary were seven, right, three. The largest diameter of the tumors ranged from 6.8 to 24 cm (mean: 11.9 cm). All had well-defined margins. Ascites was seen in four cases. Among ten cases of GCT, six were mainly solid (type 3). One case manifested as a unilocular cystic mass without mural nodule or septation. Three were multilocular cystic masses and no mural nodule was found in all three cases. Metastases to peritoneum and lymph nodes was seen in one case. The ultrasonographic findings of GCT are various but combined with clinical and laboratory findings they could be helpful in the differential diagnosis of ovarian tumors.

To evaluate the radiologic findings of granulosa cell tumor of the ovary. Fourteen cases(fifteen tumors) of pathologically confirmed ovarian granulosa cell tumor were retrospectively analyzed on the basis of CT(n=10), MR imaging(n=4), and ultrasound(n=7) findings. The patients' mean age was 44.3(range, 5-71)years. The mean diameter of the tumors was 12.1(range, 5-26.5)cm. Thirteen cases were unilateral, and one was bilateral. Eleven tumors(ten cases) were mainly solid and eight of these had focal cystic components. Multilocular cysts accounted for three cases, and in two of these, mural nodules were present. One case was a unilocular cyst with no mural nodule. Ten cases were well demarcated. All the solid tumors were enhanced on postcontrast CT and MR imaging. Endometrial thickening was seen in five cases, ascites in six, and peritoneal implants or omental fat infiltration in five. One was associated with lymph node metastasis. All the postmenopausal patients had solid tumors, whereas 66.7%(4 of 6 cases) of young adults and children had cystic tumors. Granulosa cell tumors of the ovary were solid or cystic;the former were more common. There were no characteristic findings which permitted definitive differentiation from other ovarian tumors.

Granulocyte colony-stimulating factor in toxic epidermal necrolysis (TEN) and Chelsea & Westminster TEN management protocol [corrected].

Toxic epidermal necrolysis (TEN) is a rare but life-threatening, allergic drug reaction. Skin blistering with epidermal and mucosal necrolysis with subsequent detachment from an inflamed underlying dermis is a hallmark of the condition. The pathogenesis of TEN is not well understood, accounting for controversies about its management and significant delay in initiating potentially beneficial therapy. There are no management protocols based on a robust evidence base. Prompt recognition of the diagnosis and consensus on early management initiatives are necessary in order to improve outcomes and survival in TEN. To date, TEN management has been directed at arresting the allergic reaction and treating the complications. We have identified a need for specific medical interventions to accelerate wound regeneration. This approach has not previously been adopted in the management of TEN. We observed that in two cases of severe TEN, dramatic re-epithelialization and recovery coincided with the introduction of granulocyte colony-stimulating factor (G-CSF) for neutropenia. We explain how addition of the G-CSF promotes recovery from TEN by enhanced bioregeneration of the damaged tissues through accelerated re-epithelialization. G-CSF has been used for severe neutropenia in TEN, but we recommend and explain why, as in our Chelsea and Westminster protocol, G-CSF should be considered in treating severe TEN irrespective of the severity of neutropenia.

To correlate the mammographic and ultrasonographic findings with the pathologic results in women undergoing hormone replacement therapy (HRT), and to determine the characteristic clinical, mammographic or histologic findings of breast cancer in these patients. Twenty-five breast lesions in 25 patients aged 44-65 (mean, 55.5) years undergoing HRT were surgically removed due to abnormal mammographic findings or the presence of palpable masses. Mammograms in all patients and ultrasonograms in 23 were retrospectively analyzed in terms of the shape and margin of the mass, and microcalcifications, and the imaging findings were correlated with the pathologic results. As a control group, 45 cancer patients not undergoing HRT were selected. Using the student t test, detection methods, tumor size, mammographic findings, and the proportion of intraductal cancers were compared between to two groups. Surgical excision revealed ten benign lesions (four fibroadenomas and six cases of fibrocystic change) and 15 cancers (three intraductal and twelve invasive ductal cancers). Abnormal findings at mammography were a mass in 16 cases, clustered microcalcifications in seven, and a mass with microcalcifications in two. Mammography showed that all four circumscribed masses were benign. Five of seven ill-defined masses (71%) and all six spiculated masses were malignant. Three of seven cases (43%) with microcalcifications, and both with a mass and microcalcification, were malignant. In two cases in which ultrasonography revealed cystic lesions, histologic examination showed that fibrocystic change had occurred. Compared to non-HRT-related cancers, HRT-related cancers were more often detected by mammography (60% vs 16%; p<0.001), smaller (17 mm vs 24 mm, p<0.01), showed microcalcification only (20% vs 13%; p<0.05), and were intraductal (20% vs 7%; p<0.01). In patients with HRT, mammographic findings of an ill-defined or spiculated mass, or one with microcalcifications, were associated with

Extraskeletal mesenchymal chondrosarcoma (EMC) is a rare soft-tissue tumor that most arises in young adults. Because of its rarity, few imaging studies have been reported to date. The purpose of this study was to elucidate the imaging features of this tumor. We conducted a multi-institutional study in cooperation with five referral cancer centers in Japan. Imaging findings of ten new EMC cases, including conventional radiography, computed tomography (CT), and magnetic resonance imaging (MRI), performed at each institute, were reviewed along with clinical features. Ten patients with EMC, who had been treated at each hospital from 1990 to 2001, participated in this study. Soft-tissue masses with well-demarcated, dense and granular calcification were most frequently observed on plain radiographs and CT scans. T2-weighted MR images most clearly depicted a two-component structure composed of calcified and uncalcified areas, and enhanced MRI showed inhomogeneous enhancement in both areas. Although the sensitivity and specificity of these findings are unknown, they might be characteristic and have diagnostic value for this rare tumor. (orig.)

Full Text Available Background: Human cancers comprise a large group of diseases that despite modern methods of diagnosis and advanced treatment techniques its mortality rate is high. Considering the role of environmental and cultural factors in the prevalence of oral cancer, epidemiological studies have a great importance. Objective: The aim of this research was to determine the prevalence of oral squamous cell carcinoma (OSCC in the province of Qazvin in a period of ten years. Methods: In this descriptive - analytical study, the documents of 88 patients with OSCC that were recorded by the Qazvin Cancer Registry Center during 2003-13, were used. Demographic data including age, sex and location of lesions were extracted from patient records. Data analysis were performed using chi-square, t-test and fisher exact test. Findings: Among the 88 patients, the average age was 64.3±17.7. The male to female ratio was 1 to 1.37 and the most involved area was tongue with 39 cases (63.9%, and the lowest was upper lip with 1 case (1.6%. The most of the patients were in the age between 70-80 years old. Conclusions: Pattern of OSCC in this study was similar to the other studies but the number of females and the mean age of patient had increased. Also, the mean age of patients was increased in eight decades and the most involved area tongue was reported.

Cost-effectiveness analysis of HLA-B*5801 testing in preventing allopurinol-induced SJS/TEN in Thai population.

Full Text Available BACKGROUND: Stevens-Johnson syndrome (SJS and Toxic Epidermal Necrolysis (TEN, caused by allopurinol therapy, are strongly associated with the human leukocyte antigen (HLA, HLA-B*5801. Identification of HLA-B*5801 genotype before prescribing allopurinol offers the possibility of avoiding allopurinol-induced SJS/TEN. As there is a paucity of evidence about economic value of such testing, this study aims to determine the cost-effectiveness of HLA-B*5801 testing compared with usual care (no genetic testing before allopurinol administration in Thailand. METHODS AND FINDING: A decision analytical and Markov model was used to estimate life time costs and outcomes represented as quality adjusted life years (QALYs gained. The model was populated with relevant information of the association between gene and allopurinol-induced SJS/TEN, test characteristics, costs, and epidemiologic data for Thailand from a societal perspective. Input data were obtained from the literature and a retrospective database analysis. The results were expressed as incremental cost per QALY gained. A base-case analysis was performed for patients at age 30. A series of sensitivity analyses including scenario, one-way, and probabilistic sensitivity analyses were constructed to explore the robustness of the findings. Based on a hypothetical cohort of 1,000 patients, the incremental total cost was 923,919 THB (USD 29,804 and incremental QALY was 5.89 with an ICER of 156,937.04 THB (USD 5,062 per QALY gained. The cost of gout management, incidence of SJS/TEN, case fatality rate of SJS/TEN, and cost of genetic testing are considered very influential parameters on the cost-effectiveness value of HLA-B*5801 testing. CONCLUSIONS: The genetic testing for HLA-B*5801 before allopurinol administration is considered a highly potential cost-effective intervention in Thailand. The findings are sensitive to a number of factors. In addition to cost-effectiveness findings, consideration of other

Our aim is to report the computed tomography (CT) features of the long-term failed renal allograft. Ten patients with failed renal transplants in whom the graft was left in situ underwent CT for various unrelated indications. The majority of the failed grafts showed marked shrinkage and coarse punctate diffuse parenchymal calcifications. Small cysts were seen in four grafts. A long-term failed renal transplant appeared on CT as a small rounded soft tissue mass. The graft was almost always heavily calcified. Lack of awareness of the nature of such a mass may mislead the radiologist in interpreting it as a space-occupying lesion

To evaluate CT findings of primary adenocarcinoma of the lung and to assess distant metastasis at the time of diagnosis. CT findings of 150 patients with adenocarcinoma, confirmed by histopathologic methods, were classified as central or peripheral lesion and pattern analysis of typical findings noted in this cancer was carried out. Intra and extrathoracic metastases of adenocarcinoma were also investigated. Of 150 cases of adenocarcinoma of the lung, 121 were found to be of the peripheral type and 29 were of the central type. These peripheral lesions comprised 105 nodules, 11 consolidations, four cavities and one linear lesion, while the central lesions consisted of 19 cases of atelectasis and tens of branchial wall thickening. lung to lung(nine cases), lymphangitic(five cases), and pleural metastasis(16 cases) were presented as intrathoracic metastasis, while bone(17), brain,(six), liver(two) and adrenal metastasis(one case)were presented as extrathoracic metastasis. The most common radiologic finding of adenocarcinoma is a peripheral single mass or nodule but consolidation, cavity or tubular lesions, as well as atelectasis or bronchial wall thickening alone can be presented as unusual findings of adenocarcinoma. As a consequence, it is in many cases difficult to differentially diagnose. Distant metastasis was also noted in many cases of early T-stage lesion, so to successfully manage the patient, careful evaluation of the metastasis is essential.

To analyze the radiographic and HRCT findings of Pneumocystic carinii pneumonia. We reviewed the medical records and retrospectively analysed the chest radiographs(n=31) and HRCT scans(n=17) of 31 patients with Pneumocystis carinii pneumonia who had been followed up at our institute between, 1993 and March 1998. Pneumocystis carinii pneumonia was confirmed by cytologic evaluation of sputum stained with methenamine silver(n=25) or on the basis of clinical history(n=6). The study group included 17 men and 14 women aged 28-78(average, 53.6) years. Twenty-eight patients had underlying conditions such as hematologic diseases(n=13), AIDS(n=8), malignancy(n=2), DM(n=2) and malnutrition(n=1), and three were free from underlying diseases. Twenty patients had pure Pneumocystis carinii pneumonia and 11 had combined lung diseases, namely pulmonary tuberculosis(n=4), pulmonary metastasis(n=2), bacterial pneumonia(n=2), atypical mycobacterial infection(n=1), pulmonary edema(n=1), and Kaposi' s sarcoma(n=1). Chest radiographic findings of 20 cases of pure Pneumocystis carinii pneumonia included consolidation(n=12), linear-reticular opacity(n=8), ill defined haziness(n=7), and nodules(n=6), with bilaterality in is cases and zonal predominance in ten [central(n=5), lower(n=5)]. Ancillary findings included pleural effusion(n=10), cysts(n=5), lymphadenopathy(n=4) and pneumothorax(n=1). In two patients, findings were entirely normal. HRCT findings in ten cases of pure Pneumocystis carinii pneumonia included ground-glass opacity(n=6), consolidation(n=6), linear-reticular opacity(n=8), and nodules(n=5), with bilaterallity in seven cases and zonal predominance in five [central(n=5), lower(n=2)]. Ancillary findings among these cases included pleural effusion(n=4), lymphadenopathy(n=2), cysts(n=1), and pneumothorax(n=1). HRCT findings in seven cases of Pneumocystis carinii pneumonia combined with other lung diseases included nodules(n=6), ground-glass opacity(n=5), linear-reticular opacity

The purpose of this study is to investigate the esophagographic findings of early esophageal cancer (EEC), and to compare these with the pathologic results, and to thus determine the most useful method of esophagography for detection of EEC. We examined 18 patients (M:F=16:2) with pathologically proven EEC; 17 cases were squamous cell carcinoma and one was adenocarcinoma. Tumor size, shape and location were evaluated by esophagography and the findings were compared with the pathologic results. The tumors were 0.5 - 7 cm in size; all except two were smaller than 4 cm. Twelve were located in the middle esophagus, five cases in the lower esophagus and one case in the upper esophagus; in ten cases, the margin was ill-defined. Esophagography showed that eight cases were of the superficial depressed type, seven were the superficial elevated type, and three were the tumorous type. All 18 cases were detected by double contrast study, but mucosal relief study and barium filling study revealed only ten and eight cases, respectively; for the detection of EEC double contrast study was thus the most useful. EEC was commonly demonstrated in the middle esophagus with an ill-defined margin; it was of the superficial depressed or elevated type. For the detection of EEC, double contrast study was the most useful. (author). 14 refs., 1 tab., 5 figs

Mucinous carcinoid of the ovary: report of a case with metastasis in the contralateral ovary after ten years

Directory of Open Access Journals (Sweden)

Patricia C. Ewing

2010-09-01

Full Text Available Monodermal teratomas of the ovary can take the form of carcinoid tumors of which there are several types, mucinous carcinoid being the least common. Very few cases of primary mucinous carcinoid of the ovary have been reported in the literature and the behavior of these tumors over the long term is unclear. We describe a case of primary mucinous carcinoid of the ovary in a 39-year-old woman treated with unilateral salpingo-oophorectomy, where a metastasis occurred in the contralateral ovary ten years later. This case demonstrates that mucinous carcinoid of the ovary can metastasize even after a long interval, and careful follow-up of patients, particularly those treated conservatively, is appropriate.

The purpose of this study is to analyze the CT features of the cystic masses in the neck and to review differential diagnosis. We retrospectively reviewed and analyzed the CT findings of 22 histopathologically proved, cystic neck masses in regard to the location in fascial plane and relationship with adjacent organ. Of 22 cases, ten congenital cysts two ranulas, seven inflammatory lesions, and three solid tumors were included. Ten congenital cystic masses were located in typical locations as branchial cleft cyst (5) in mandibular angle, thyroglossal duct cyst (3) in visceral space embeded within the strap muscles, cystic hygroma (1) and cavernous hemangioma (1) in posterior cervical space with insinuating appearance. Two cases of ranula included one simple ranula localized in sublingual space and a plunging ranula extending to adjacent submandibular space. Seven cases of inflammatory lesions were characterized by multispatial locations and good contrast-enhancement of walls and adjacent tissue. Solid masses of low density mimicking cyst were two pleomorphic adenomas of submandibular gland and one neurilemmoma. It is considered that thorough analysis of the CT findings with attention to typical location, CT appearance, and the relationship with the adjacent structures usually leads to the correct diagnosis.

It is now considered a good practice to integrate these tools as part of your development process. The Linux project, for instance, has an automated testing...... service, known as the Kbuild robot, that runs a few of these code scanners. In this project, I have carefully studied tens of historical Linux bugs, and I have found that many of these bugs, despite being conceptually simple, were not caught by any code scanning tool. The reason is that, by design, code...... scanners will find mostly superficial errors. Thus, when bugs span multiple functions, even if simple, they become undetectable by most code scanners. The studied set of historical bugs contained many of such cases. This PhD thesis proposes a bug-finding technique that is both lightweight and capable...

Objective: To retrospectively review the imaging features of surgically and pathologically confirmed intracranial hemangiopericytoma and anaplastic hemangiopericytoma. Methods: Thirty-nine cases of surgically and pathologically confirmed hemangiopericytoma and anaplastic hemangiopericytoma were analyzed retrospectively. The MRI features were compared with pathological findings in all cases. Results: Of the 39 cases, 21 were anaplastic hemangiopericytoma (WHO grade III) and the remaining cases were hemangiopericytoma (WHO grade II); all lesions were solitary. MRI of anaplastic hemangiopericytoma showed that 20 cases were lobulated, and nine grew cross-leaf. The lesions showed mixed iso-high-low signal (n = 20) or iso-signal (n = 1) on plain T1WI, and mixed high-low signal (n = 20) or iso-signal (n = 1) on plain T2WI. After contrast injection, marked heterogeneous enhancement was seen in 19 cases. Significant necrosis and cystic changes were seen in 16 cases, and the “dural tail sign” was found in two cases. Ten cases had bony destruction, and 16 showed significant peritumoral edema. In 18 cases of hemangiopericytoma, nine were oval-shaped and three grew cross-leaf. The lesions showed mixed iso-low signal (n = 10) or iso-signal (n = 8) on plain T1WI, and mixed iso-high signal (n = 10) or iso-signal (n = 8) on plain T2WI. After contrast injection, significant uniform enhancement was seen in 10 cases. Significant necrosis and cystic changes were seen in seven cases, and “dural tail sign” was seen in six cases. Two cases had bony destruction. No case showed significant peritumoral edema. Pathological immunohistochemical Ki67 staining showed a concentration of ∼18.4% positive cells in anaplastic hemangiopericytoma, whereas in hemangiopericytoma it was 7.12%. Conclusion: Imaging findings of intracranial anaplastic hemangiopericytoma had more pronounced lobulation, cross-leaf growth tendency, more and easier bleeding, more necrosis, more cystic changes giving

To evaluate the effectiveness of a social marketing model on case-finding for COPD in a population with high smoking rates and COPD prevalence. A two-week marketing campaign was conducted using high visibility posters, leaflets distributed with the local newspaper, and the creation of a free automated COPD information line. The primary outcome measure was the number of newly-diagnosed cases of COPD as a result of the campaign. Secondary outcomes measures were: the number of phone calls to the information line up to four weeks after the end of the campaign; the number of individuals who presented to their general practitioner (GP) for spirometry as a result of the campaign; and responses to a questionnaire sent to members of the public to analyse and assess the visibility and impact of the campaign. Ten people came forward to have spirometry performed and all had non-obstructive results. Nine calls were made to the dedicated COPD phone line. 135 out of 400 members of the public (34%) responded to the questionnaire; of these, only 34 (25%) recalled seeing a campaign poster. Posters and leaflets from this campaign were visible but only led to 10 individuals coming forward for spirometry, none of whom had COPD. This form of healthcare marketing was costly and not effective for COPD case-finding in our area.

Alkaptonuria is a rare disease with autosomal recessive inheritance and variable expression. The weight-bearing joint involvement and spondylitis-like vertebral changes occur only after the 3rd decade. Musculoskeletal ultrasonographic findings in alkaptonuria were only rarely described, consisting mainly into enthesopathy and non-synovial tendon degeneration. We present the case of a 50 years old man with alkaptonuria and discuss the ultrasonographic findings and the relationship of the disease with chondrocalcinosis. The tendinous and synovial aspect may be peculiar and it could therefore allow recognition and screening for alkaptonuria, along with clinical and radiologic data.

Although dissociative trance disorders, especially possession disorder, are probably more common than is usually though, precise clinical data are lacking. Ten persons undergoing exorcisms for devil trance possession state were studied with the Dissociative Disorders Diagnostic Schedule and the Rorschach test. These persons had many traits in common with dissociative identity disorder patients. They were overwhelmed by paranormal experiences. Despite claiming possession by a demon, most of them managed to maintain normal social functioning. Rorschach findings showed that these persons had a complex personality organization: Some of them displayed a tendency to oversimplify stimulus perception whereas others seemed more committed to psychological complexity. Most had severe impairment of reality testing, and 6 of the participants had an extratensive coping stile. In this group of persons reporting demon possession, dissociative trance disorder seems to be a distinct clinical manifestation of a dissociative continuum, sharing some features with dissociative identity disorder.

The authors report the findings of Aicardi syndrome, a disease of unknown etiology composed of multiple spasms, chorioretinal lacunae and agenesis of the corpus callosum. They present a case of Aicardi syndrome with characteristic clinical presentation and magnetic resonance imaging findings. The disease, despite being considered rare, has characteristic imaging findings. Over the past years magnetic resonance imaging has improved its ability in demonstrating other findings besides agenesis of the corpus callosum, making the radiologist's role very important in the diagnostic suspicion of this disease.

Full Text Available A systematical evaluation work was performed on ten widely used and high-efficient QRS detection algorithms in this study, aiming at verifying their performances and usefulness in different application situations. Four experiments were carried on six internationally recognized databases. Firstly, in the test of high-quality ECG database versus low-quality ECG database, for high signal quality database, all ten QRS detection algorithms had very high detection accuracy (F1 >99%, whereas the F1 results decrease significantly for the poor signal-quality ECG signals (all 95% except RS slope algorithm with 94.24% on normal ECG database and 94.44% on arrhythmia database. Thirdly, for the paced rhythm ECG database, all ten algorithms were immune to the paced beats (>94% except the RS slope method, which only output a low F1 result of 78.99%. At last, the detection accuracies had obvious decreases when dealing with the dynamic telehealth ECG signals (all <80% except OKB algorithm with 80.43%. Furthermore, the time costs from analyzing a 10 s ECG segment were given as the quantitative index of the computational complexity. All ten algorithms had high numerical efficiency (all <4 ms except RS slope (94.07 ms and sixth power algorithms (8.25 ms. And OKB algorithm had the highest numerical efficiency (1.54 ms.

Cerebral computed tomography (CT) findings were described in twenty-six cases with the late sequelae of acute carbon monoxide poisoning and were computed with the neurological symptoms and signs. The CT findings include symmetrical periventricular white matter low density in five cases, globes pallidus low density in six cases, ventricular dilatation in seven cases, ventricular dilatation and sulci widening in three cases, and normal findings in ten cases. Only one case showed low densities in both periventricular white matter and globes pallidus. Late sequelae of the interval from of carbon monoxide poisoning were clinically categorized as cortical dysfunction, parkinsonian feature, and cerebella dysfunction. The severity of the clinical symptoms and signs of neurological sequelae is generally correlated with presence and multiplicity of abnormal brain CT findings. But of fourteen cases showing the parkinsonian feature, only five cases had low density of globes pallidus in brain CT. Another case showing small unilateral low density of globes pallidus had no parkinsonian feature but showed mild cortical dysfunction.

Fascioliasis is a disease caused by the trematode Fasciola hepatica. Cholangitis is a common clinical manifestation. Although fascioliasis may show various radiological and clinical features, cases without biliary dilatation are rare. We present unique ultrasound (US) and magnetic resonance cholangiopancreatography (MRCP) findings of a biliary fascioliasis case which doesn’t have biliary obstruction or cholestasis. Radiologically, curvilinear parasites compatible with juvenile and mature Fasciola hepatica within the gallbladder and common bile duct were found. The parasites appear as bright echogenic structures with no acoustic shadow on US and hypo-intense curvilinear lesions on T2 weighted MRCP images. Imaging studies may significantly contribute to the diagnosis of patients with subtle clinical and laboratory findings, particularly in endemic regions

Isolated breast vasculitis manifested as breast edema with suggestive sonographic findings: a case report with imaging findings.

Science.gov (United States)

2017-04-01

Early diagnosis of breast vasculitis (BV) is difficult because this condition is rare and occasionally mimics breast cancer clinically or radiologically. It may present as systemic disease or as an isolated lesion in the breast, without systemic evidence. When vasculitis appears in the breast, it also might manifest as a tumor-like lesion, and in previous cases, tissue acquisition was needed for confirmation of the diagnosis because of BV's resemblance to inflammatory breast cancer. We report a case of isolated BV that was suspected of being inflammatory breast cancer clinically, but manifested as bilateral breast edema on mammography. In this case, sonographic findings included not only nonspecific edema findings that might be seen in other cases, but also suggestive findings of hypoechoic circumferential arterial wall thickening with perivascular fat infiltrations that are similar to the halo sign in large arteries but have not been reported in the breast. These are helpful for presumptive diagnosis of BV using ultrasound.

Endometriosis in the abdominal wall is a rare condition that most commonly occurs in the physiological scar of the umbilicus and in surgical scars of pelvic operation. The ultrasonographic findings are often non-specific, but with scrutinized physical examination and history, correct diagnosis can be made. We report ultrasonographic findings of abdominal wall endometriosis in two cases, both of which were related to previous cesarian section scar

Dose-specific effects of transcutaneous electrical nerve stimulation (TENS) on experimental pain: a systematic review.

2011-09-01

To determine the hypoalgesic effects of transcutaneous electrical nerve stimulation (TENS) parameter combinations on experimental models in healthy humans. Searches were performed using the electronic databases Ovid MEDLINE, CINAHL, AMED, and Web of Science (from inception to December 2009). Manual searches of journals and reference lists of retrieved trials were also performed. Randomized controlled trials (RCTs) were included in the review if they compared the hypoalgesic effect of TENS relative with placebo and control, using an experimental pain model in healthy human participants. Two reviewers independently selected the trials, assessed their methodologic quality and extracted data. Forty-three RCTs were eligible for inclusion. A best evidence synthesis revealed: Overall "conflicting" (inconsistent findings in multiple RCTs) evidence of TENS efficacy on experimental pain irrespective of TENS parameters used. Overall intense TENS has "moderate" evidence of efficacy (1 high-quality and 2 low-quality trials). Conventional TENS has overall conflicting evidence of efficacy, this is derived from "strong" evidence of efficacy (generally consistent findings in multiple high-quality RCTs) on pressure pain but strong evidence of inefficacy on other pain models. "Limited" evidence (positive findings from 1 RCT) of hypoalgesia exists for some novel parameters. Low-intensity, low-frequency, local TENS has strong evidence of inefficacy. Inappropriate TENS (using "barely perceptible" intensities) has moderate evidence of inefficacy. The level of hypoalgesic efficacy of TENS is clearly dependent on TENS parameter combination selection (defined in terms of intensity, frequency, and stimulation site) and experimental pain model. Future clinical RCTs may consider these TENS dose responses.

Ultrasound Findings in Tension Pneumothorax: A Case Report.

Inocencio, Maxine; Childs, Jeannine; Chilstrom, Mikaela L; Berona, Kristin

2017-06-01

Delayed recognition of tension pneumothorax can lead to a mortality of 31% to 91%. However, the classic physical examination findings of tracheal deviation and distended neck veins are poorly sensitive in the diagnosis of tension pneumothorax. Point-of-care ultrasound is accurate in identifying the presence of pneumothorax, but sonographic findings of tension pneumothorax are less well described. We report the case of a 21-year-old man with sudden-onset left-sided chest pain. He was clinically stable without hypoxia or hypotension, and the initial chest x-ray study showed a large pneumothorax without mediastinal shift. While the patient was awaiting tube thoracostomy, a point-of-care ultrasound demonstrated findings of mediastinal shift and a dilated inferior vena cava (IVC) concerning for tension physiology, even though the patient remained hemodynamically stable. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case demonstrates a unique clinical scenario of ultrasound evidence of tension physiology in a clinically stable patient. Although this patient was well appearing without hypotension, respiratory distress, tracheal deviation, or distended neck veins, point-of-care ultrasound revealed mediastinal shift and a plethoric IVC. Given that the classic clinical signs of tension pneumothorax are not uniformly present, this case shows how point-of-care ultrasound may diagnose tension pneumothorax before clinical decompensation.

Full Text Available Xeroderma pigmentosum (XPis a rare inherited skin disorder characterized by a heightened sensitivity to the DNA damaging effects of ultraviolet radiation (UV. The main source of UV is the sun. The symptoms of XP can be seen in any sun-exposed area of the body. The effects are greatest on the skin, the eyelids and the surface of the eyes but the tip of the tongue may also be damaged. In addition, approximately 25% of XP patients also develop abnormalities of the nervous system manifesting as progressive neuro-degeneration with hearing loss. People with XP have a 10,000-fold increased risk for developing skin cancer including basal cell carcinoma, squamous cell carcinoma and melanoma. They also have a 2000-fold increased risk for cancer of the eye and surrounding ocular tissues. These symptoms appear early in life, typically before age 10 years. This case is being presented to highlight the rarity of a case of xeroderma pigmentosum with squamous cell carcinoma in a ten year old child.

The routine tuberculosis (TB) surveillance system in Cambodia has been strengthened under the National TB Programme (NTP). This paper provides an overview of the TB surveillance data for Cambodia at the national level for the period 2000 to 2013 and at the subnational level for 2013. The proportion of the total population that were screened for TB rose from 0.4% in 2001 to 1.1% in 2013, while the smear-positivity rate decreased from 28.9% to 8.1% in the same period. The total number of notified TB cases increased steadily from 2000; this has stabilized in recent years with 39 055 cases notified in 2013. The proportion of all TB cases that were smear-positive decreased from 78% in 2000 to 36% in 2013. Case notification rates (CNRs) for all forms of TB and new smear-positive TB in 2013 were 261 and 94 per 100 000 population, respectively. Higher CNRs were found in the north-western and south-eastern parts of the country and were higher for males especially in older age groups. The increase in TB screening, decline in the smear-positive rate and decline in notified smear-positive TB cases likely reflect a long-term positive impact of the NTP. A negative correlation between the proportion of the population screened and the smear-positivity rate at the subnational level helped identify where to find undiagnosed cases. Subnational differences in case notification of the elderly and in children provide more specific targets for case-finding and further encourage strategic resource allocation. PMID:25960919

2010-11-01

Full Text Available Abstract Introduction Composite tumors of the adrenal medulla or paraganglia are extremely rare and present a diagnostic dilemma. These tumors consist of a neuroendocrine component mixed with a neural component. We describe the imaging characteristics together with the corresponding pathological findings of a composite tumor. Apart from any component-specific imaging findings, the hallmark of this entity is the presence of histologically distinguishable components. Case presentation A 61-year-old Caucasian man was referred to our hospital due to a suspect lesion found on chest computed tomography carried out for unclear thoracic pain. An abdominal computed tomography scan and ultrasound examination detected a retroperitoneal tumor comprising two different tumor components. Twenty-four-hour urine revealed high levels of normetanephrine, characteristic of a neuroendocrine tumor. An octreoscan prior to surgical procedures revealed multiple osseous and intra-hepatic metastases. The final histopathological workup revealed a composite paraganglioma with neuroblastoma. Our patient died ten months after the initial diagnosis from tumor-associated complications. Conclusions Composite paragangliomas with neuroblastoma are rare tumors of the retroperitoneum. Such tumors should be considered in the differential diagnosis of retroperitoneal masses.

To evaluate the radiographic findings of gastrointestinal anisakiasis with clinical and pathologic correlation. In ten patients, findings were retrospectively analysed. There were two cases of the gastric variety of gastrointestinal anisakiasis and eight of the intestinal, and they were diagnosed during gastroscopy, by resection during surgery, and on the basis of typical clinical findings. All ten patients underwent both plain radiography and CT scanning of the abdomen. US was performed in five patients and an upper gastrointestinal series in one. Clinical data were evaluated with regard to a history of raw fish ingestion, time from ingestion of raw fish to onset of symptoms, location of abdominal pain, and laboratory data. Radiologic findings were analysed in terms of wall thickening and appearance, mesenteric infiltration, bowel dilatation proximal to lesion, and ascites. All patients had a history of recent ingestion of raw fish and complained of severe abdominal pain that occurred approximately 7-48 hours later. Pain occurred in the lower abdomen in five patients, the epigastrium in four, and the right lower abdomen in two. Laboratory test disclosed the leukocytosis in eight patients and eosinophilia in three. In all cases of intestinal anisakiasis, ileus was demonstrated on plain radiographs of the abdomen, while the upper gastrointestinal series showed mucosal thickening and multiple filling defects. US findings were bowel thickening and dilation, and on CT images, wall thickening revealed a target sign. Mesenteric infiltration and ascites were seen in seven patients. In four who underwent surgery, a cross-section through the lesion revealed submucosal eosinophilic granuloma with anisakis larva. Although the CT findings are non-specific, taken in conjunction with characteristic clinical findings, they may be helpful in the diagnosis of gastrointestinal anisakiasis. (author)

Compared with the well documented neurophysiological findings on negative emotions, much less is known about positive emotions. In the present study, we explored the EEG correlates of ten different positive emotions (joy, gratitude, serenity, interest, hope, pride, amusement, inspiration, awe, and love). A group of 20 participants were invited to watch 30 short film clips with their EEGs simultaneously recorded. Distinct topographical patterns for different positive emotions were found for the correlation coefficients between the subjective ratings on the ten positive emotions per film clip and the corresponding EEG spectral powers in different frequency bands. Based on the similarities of the participants' ratings on the ten positive emotions, these emotions were further clustered into three representative clusters, as 'encouragement' for awe, gratitude, hope, inspiration, pride, 'playfulness' for amusement, joy, interest, and 'harmony' for love, serenity. Using the EEG spectral powers as features, both the binary classification on the higher and lower ratings on these positive emotions and the binary classification between the three positive emotion clusters, achieved accuracies of approximately 80% and above. To our knowledge, our study provides the first piece of evidence on the EEG correlates of different positive emotions.

Gallbladder specimens are routinely sent for histopathological examination after cholecystectomy in order to rule out the presence of unexpected pathological findings. To establish the overall incidence of unexpected pathological findings in patients who underwent laparoscopic cholecystectomy for symptomatic gallbladder disease and determine whether the macroscopic appearance of the gallbladder in ultrasound examination could be a valid method for identifying patients with gallbladder malignancy. A retrospective study was conducted between 2013 and 2015. All histological reports (n = 1131) after cholecystectomy were searched for unexpected pathological findings. In cases where unexpected pathological findings were identified the additional analysis of preoperative abdominal ultrasound examination (USG) was done to determine the usefulness of USG in diagnosis of gallbladder malignancy. Of the 1131 patients included in the study, 356 (31.47%) were male and 774 (68.43%) were female. Unexpected pathological findings were present in 21 cases. The overall incidence of unexpected pathological findings was 1.86%. Only in 5 patients were suspicious appearances of gallbladder observed in preoperative ultrasound examination. In 16 patients there was no suspicion of malignancy. The positive predictive value of USG was 0.238. The incidence of unexpected pathological findings after laparoscopic cholecystectomy was 1.86%. Ultrasonography has low positive predictive value for identifying patients with malignant findings in a gallbladder specimen.

The purpose of this study was to evaluate the MRI findings of well-differentiated liposarcoma. Ten well-differentiated liposarcomas surgically excised with histologic diagnosis were included in this study. The subjects consisted of five men and five women, with an average age of 62.5 years (range: 43-79 years). Six cases occurred in the thigh, two in the forearm, one in the shoulder, and one in the chest wall. Thickened septa (generally ≥2 mm) of low T1 signal and high T2 signal, and prominent area of enhancement were suspicious for well-differentiated liposarcoma. So we checked these lesions and compared with the pathologic findings of these lesions. Thick septa and prominent area of enhancement were identified in all cases except one case who could not use Gadolinium. Pathologically, these lesions were composed of a relatively mature adipocytic proliferation in which, in contrast to benign lipoma, significant variation in cell size is easily appreciable. So we consider that thick septa and prominent area of enhancement are evidently suspicious lesions for well-differentiated liposarcoma. (author)

The findings in two patients with histologically proven synovial hemangioma of the knee are described. Both cases emphasize the typical appearance of this unusual tumor on magnetic resonance imaging. Additional radiologic findings, such as adjacent osseous insolvement, are discussed. The MRI findings of this tumor are highly suggestive of the diagnosis and MRI should eliminate the need for invasive angiographic procedures. (orig.)

We retrospectively analysed the clinical and CT findings of 24 cases with tuberous sclerosis with special emphasis upon the atypical presentation. The cases with classic clinical triad were accounted for in 21%, while 33% presented with atypical clinical features. The most common and characteristic CT finding is that of the subependymal calcified nodules of the lateral ventricle, which was seen in 85% of our cases. Cortical tuber and white matter lesions were demonstrated in 65% and 55%, respectively. Three cases showed cortical tuber and white matter lesion without subependymal tuber. The cortical tuber usually exhibited low density or calcified lesion, but showed high density in 2 cases. Other findings of tuberous sclerosis included intraventricular tumor, ventriculomegaly, and cortical atrophy. One case clearly demonstrated parenchymal tuber on MR imaging. In conclusion, diagnosis of tuberous sclerosis is usually made on the clinical bases initially. However, CT and MR are also diagnostic even in unusual clinical presentation such as unexplained retardation or epilepsy or when the classic clinical triad is incomplete. If only cortical tuber or white matter lesion is present, it is difficult to diagnose tuberous sclerosis and to differentiate from other cortical mass lesion. Therefore, careful evaluation is required with familiarity with the atypical appearance of the disease

Cape Town, South Africa. To model the effects of increased case finding and triage strategies on laboratory costs per tuberculosis (TB) case diagnosed. We used a validated operational model and published laboratory cost data. We modelled the effect of varying the proportion with TB among presumptive cases and Xpert cartridge price reductions on cost per TB case and per additional TB case diagnosed in the Xpert-based vs. smear/culture-based algorithms. In our current scenario (18.3% with TB among presumptive cases), the proportion of cases diagnosed increased by 8.7% (16.7% vs. 15.0%), and the cost per case diagnosed increased by 142% (US$121 vs. US$50). The cost per additional case diagnosed was US$986. This would increase to US$1619 if the proportion with TB among presumptive cases was 10.6%. At 25.9-30.8% of TB prevalence among presumptive cases and a 50% reduction in Xpert cartridge price, the cost per TB case diagnosed would range from US$50 to US$59 (comparable to the US$48.77 found in routine practice with smear/culture). The operational model illustrates the effect of increased case finding on laboratory costs per TB case diagnosed. Unless triage strategies are identified, the approach will not be sustainable, even if Xpert cartridge prices are reduced.

To analyze the MR findings of chondroblastoma and peritumoral bone marrow, focussing on the enhancement pattern. Enhanced MR images obtained from 23 patients with pathologically proven chondroblastoma were retrospectively reviewed by three radiologists. The enhancement pattern was classified as one of three types: homogeneous, heterogeneous, or peripheral rim, while peritumoral bone marrow enhancement was assigned one of four grades. Correlation between the enhancement pattern and T2 signal intensity of a tumor was analyzed by fisher's exact test. The enhancement pattern was homogeneous in ten cases, heterogeneous in six, and involved the peripheral rim in seven. In 11 cases, peritumoral bone marrow enhancement was observed. Among the ten instances of homogeneous enhancement the signal intensity seen at T2W1 was homogeneously iso or low in six cases, homogeneously high in two, and heterogeneous in two. Among the seven cases in which three was peripheral rim enhancement, the signal intensity observed at T2W1 was homogeneously high in three, fluid-fluid level in three, and homogeneously iso or low in one. At MR imaging, chondroblastoma shows variable signal intensities and enhancement patterns. The peripheral rim enhancement observed at T2W1 correlated with homogeneously high signal intensity or fluid-fluid levels

To evaluate the ultrasonographic findings of lateral epicondylitis and their relationship with clinical outcome. The findings of ultrasonographic examinations of eighteen elbow joints in 15 patients (M:F=5:10; age:38-65(mean, 47.6) years) with lateral epicondylitis were reviewed. Two patients underwent surgery, two were not treated, and the remaining 11 were treated conservatively. Symptomatic improvement was noted 1 week after conservative treatment in two cases, at 2 weeks in five cases, at 3 weeks in three cases, and at 5 weeks in one case. With patients in the 90 degree flexed elbow position and in a supinated wrist, weexamined the extensor carpi radialis brevis (ECRB) tendon around the lateral epicondyle using ultrasound equipment with a 7-11 MHz linear transducer. The findings were assessed in terms of swelling of the tendon, changes in its echotexture, the presence of calcification of cystic degeneration, loss of the hypoechoic band between the tendon and bony cortex of the lateral epicondyle, cortical irregularity of the lateral epicondyle, and fluid collection around the tendon. Any relationships between each ultrasonographic finding and the treatment interval after which symptomatic improvement was noted were evaluated. In the 18 joints, change was heterogeneous hypoechogenicity in 13, and heterogeneous mixed echogenicity in three. Other ultrasonographic findings were swelling of the tendon in ten cases, loss of the hypoechoic band in 14, cortical irregularity in five, calcification in four, cystic degeneration in nine, and fluid collection around the tendon in four. In patients treated conservatively, there was no statistically significant difference between each ultrasonographic finding and the treatment interval after which symptomatic improvement was noted. Ultrasonography can be used to assess changes in the ECRB tendon and lateral epicondyle occurring in lateral epicondylitis, but fails to provide information on the rapidity of symptomatic

We describe the imaging features of two cases of biliary ascariasis. Ultrasonography and CT showed no specific abnormal findings, but MR cholangiography clearly demonstrated an intraductal linear filling defect that led to the correct diagnosis. MR cholangiography is thus a useful technique for the diagnosis of biliary ascariasis

Ganglioglioma is a rare primary brain tumor usually found in the temporal lobe. The purpose of this study is to describe the characteristic MR findings of temporal lobe ganglioglioma. Over a seven-year period, ten patients with cerebral ganglioglioma were evaluated at our institution. Seven cases of temporal lobe ganglioma were found ; six of these involved men, and one, a woman ; their mean age was 29.6 years. In three patients, Gd-DTPA-enhanced T1-weighted images were also obtained. We retrospectively analysed the MRI findings with respect to location, size, cortical involvement, margin, cystic change, degree of enhancement, MR signal intensity, calcification and peritumoral change. In five cases, tumors were located within the temporal lobe. In one, a tumor extended from the temporal lobe to the thalamus, and in one from the temporal lobe to the thalamus and cerebral peduncle. All temporal gangliogliomas measured 1.6-3.8cm in their greatest diameter (mean diameter, 2.7cm). In all cases, the cortices were involved with the maintenance of gyriform. The tumor margin was ill defined in five cases and well defined in two. Tumors showed multiple small cystic changes in four cases, a large cyst in two, and a solid nodule in one. In three cases in which contrast media was administered, no lesions were enhanced. On T1-weighted images, iso-signal intensities were seen in five cases and high signal intensities in two. On T2-weighted images, the corresponding figures were five and two. On MRI, tumor calcification and calvarial erosion were each detected in two cases. In patients with temporal lobe epilepsy in whom cortical solid or cystic and poorly enhanced lesions were seen on brain MRI, and in whom associated findings such as calcification and or adjacent bony erosion were noted, ganglioglioma must be considered

In 1990, DOE initiated a nationwide evaluation of its Weatherization Program, with assistance from Oak Ridge National Laboratory and an advisory group of 40 weatherization professionals, program managers, and researchers. The evaluation is comprised of three impact studies covering the Program`s major market segments: Single-family homes, mobile homes, and dwellings in small (2 to 4-unit) multifamily buildings (the Single-Family Study), Single-family homes heated primarily with fuel oil (the Fuel-Oil Study), and Dwellings in buildings with five or more units (the Multifamily Study). The Single-Family Study, the subject of this report, is a critical part of this coordinated evaluation effort. Its focus on single-family dwellings, mobile homes, and dwellings in small multifamily buildings covers 83% of the income-eligible population and 96% of the dwellings weatherized during Program Year 1989. The first phase of the Single-Family Study involved the analysis of a massive data base of information collected from 368 local weatherization agencies and 543 electric and gas utilities. This analysis resulted in energy-saving and cost-effectiveness estimates for the Weatherization Program and the identification of a set of ten high-performing agencies located throughout the country. The second phase, which is the subject of this report, involves a ``process`` evaluation of these ten high performers, aimed at identifying those weatherization practices that explain their documented success.

Full Text Available AIM: To compare the optometric examination results of myopic young children between those diagnosed in the period from 1998 to 2000 and those diagnosed in the period from 2008 to 2010; and to find out the causes of myopia and factors that worsen the condition, and suggest methods of its prevention and treatment.METHODS: This study was a retrospective case study. We randomly selected sample from out-patient department register of cases and divided them into two main groups, ‘ten year before group'(TYBG(1998/2000 year casesand ‘ten years later group'(2008/2010 year cases(TYLG. Each group was further subdivided into three sub-groups by age: under-six years old children group(CG, seven-twelve years old primary-school group(PSGand thirteen-eighteen years old middle-school group(MSG. The optometric examination results were statistically analyzed.RESULTS: The difference of the mean dioptre between the TYBG and TYLG was strongly statistically significant, also forward-lead trend of age when children suffered from myopia was found(P0.01. There was a significant increase of dioptre among PSG and MSG in TYLG compared to TYBG(PCONCLUSION: Our study shows that the age of getting myopia was forward lead, the dioptre increases by 1.00 degree and the prevalence of myopia is increasing gradually. This situation may due to the modern life style and changes of living standard of the population. Therefore, prevention of myopia should concentrate more on younger children at kindergarten and primary school stage students.

To evaluate the need for triangulating case-finding tools in patient safety surveillance. This study applied four case-finding tools to error-associated patient safety events to identify and characterise the spectrum of events captured by these tools, using puncture or laceration as an example for in-depth analysis. Retrospective hospital discharge data were collected for calendar year 2005 (n=48,418) from a large, urban medical centre in the USA. The study design was cross-sectional and used data linkage to identify the cases captured by each of four case-finding tools. Three case-finding tools (International Classification of Diseases external (E) and nature (N) of injury codes, Patient Safety Indicators (PSI)) were applied to the administrative discharge data to identify potential patient safety events. The fourth tool was Patient Safety Net, a web-based voluntary patient safety event reporting system. The degree of mutual exclusion among detection methods was substantial. For example, when linking puncture or laceration on unique identifiers, out of 447 potential events, 118 were identical between PSI and E-codes, 152 were identical between N-codes and E-codes and 188 were identical between PSI and N-codes. Only 100 events that were identified by PSI, E-codes and N-codes were identical. Triangulation of multiple tools through data linkage captures potential patient safety events most comprehensively. Existing detection tools target patient safety domains differently, and consequently capture different occurrences, necessitating the integration of data from a combination of tools to fully estimate the total burden.

Implementation fidelity of self-administered transcutaneous electrical nerve stimulation (TENS) in patients with chronic back pain: an observational study.

2014-03-01

The efficacy of transcutaneous electrical nerve stimulation (TENS) for pain relief has not been reliably established. Inconclusive findings could be due to inadequate TENS delivery and inappropriate outcome assessment. Electronic monitoring devices were used to determine patient compliance with a TENS intervention and outcome assessment protocol, to record pain scores before, during, and after TENS, and measure electrical output settings. Patients with chronic back pain consented to use TENS daily for 2 weeks and to report pain scores before, during, and after 1-hour treatments. A ≥ 30% reduction in pain scores was used to classify participants as TENS responders. Electronic monitoring devices "TLOG" and "TSCORE" recorded time and duration of TENS use, electrical settings, and pain scores. Forty-two patients consented to participate. One of 35 (3%) patients adhered completely to the TENS use and pain score reporting protocol. Fourteen of 33 (42%) were TENS responders according to electronic pain score data. Analgesia onset occurred within 30 to 60 minutes for 13/14 (93%) responders. It was not possible to correlate TENS amplitude, frequency, or pulse width measurements with therapeutic response. Findings from TENS research studies depend on the timing of outcome assessment; pain should be recorded during stimulation. TENS device sophistication might be an issue and parameter restriction should be considered. Careful protocol design is required to improve adherence and monitoring is necessary to evaluate the validity of findings. This observational study provides objective evidence to support concerns about poor implementation fidelity in TENS research.

Medico-legal findings, legal case progression, and outcomes in South African rape cases: retrospective review.

Full Text Available BACKGROUND: Health services for victims of rape are recognised as a particularly neglected area of the health sector internationally. Efforts to strengthen these services need to be guided by clinical research. Expert medical evidence is widely used in rape cases, but its contribution to the progress of legal cases is unclear. Only three studies have found an association between documented bodily injuries and convictions in rape cases. This article aims to describe the processing of rape cases by South African police and courts, and the association between documented injuries and DNA and case progression through the criminal justice system. METHODS AND FINDINGS: We analysed a provincially representative sample of 2,068 attempted and completed rape cases reported to 70 randomly selected Gauteng province police stations in 2003. Data sheets were completed from the police dockets and available medical examination forms were copied. 1,547 cases of rape had medical examinations and available forms and were analysed, which was at least 85% of the proportion of the sample having a medical examination. We present logistic regression models of the association between whether a trial started and whether the accused was found guilty and the medico-legal findings for adult and child rapes. Half the suspects were arrested (n = 771, 14% (209 of cases went to trial, and in 3% (31 of adults and 7% (44 of children there was a conviction. A report on DNA was available in 1.4% (22 of cases, but the presence or absence of injuries were documented in all cases.

Kim, Jong Chul; Kim, Young Wol

1996-01-01

To differentiate mature and immature ovarian teratomas, using CT findings. The CT findings of ten mature ovarian teratomas (in one patient, bilateral) and ten which were immature were compared, using statistical analysis. Images were evaluated for size, margins, architecture, contents (mural nodules, fat, calcification), septa, local invasion and distant metastasis. These findings were compared with pathologic findings. Of the ten mature tumors, nine were well defined and predominantly cystic in internal architecture, and one was mixed. Mural nodules were found in six tumor, fat in all, distinct calcification in seven, and regular septa in three lesions. Of the ten immature humors, eight had irregular margins. Seven were predominantly solid in internal architecture and irregularly enhanced, two were mixed, and one was mainly cystic. Fat was detected in five lesions, indistinct scattered calcification in six, irregular septa in three, and local invasion of distant metastasis in four patients. Compared with mature ovarian teratomas, those that are immature tend to show CT findings of marginal irregularity, solid mass with irregular enhacement, scattered indistinct calcifications, septal irregularity, local invasion or distant metastasis. Our experience suggests that these findings may be helpful in differentiation of mature and immature ovarian teratomas

How did General Surgery Department of a Training Hospital Change in Ten Years?

Full Text Available  Aim: To investigate the changes in a training hospital’s surgical patient profile in ten years. To delineate the effects of the transfer of Social Security Institution Hospitals to the Ministry of Health on this process. Material and Method: Ten-year apart, two-year periods were selected and all elective and emergency cases were retrospectively searched. In between periods, the hospital was transferred from Social Security Institution Hospital to the Ministry of Health and then became a trauma center. The indications, techniques, the number of performed surgeries, and the patient related factors were compared. The ratio of the number emergency cases and the number of cases performed by residents in training to the total number of cases were investigated. Results: The number of elective and emergent operations during the former and the latter periods were 2668 and 2041, respectively. The percentage of the decrease was 23.5%. After ten years, the patients were younger, more commonly male, emergency cases were more common, and operations performed primarily by the residents in training were less frequent than the former period (p<0,05. Oncological surgery of stomach, colon-rectum, breast, thyroid and primary-metastatic-malign carcinoma were more frequent during former period whereas urgent operations except peptic ulcer perforation and upper gastrointestinal bleeding and benign anorectal diseases were more common during later period (p<0,05. Discussion: The comparison revealed a significant decrease in the number of operations in ten years. The number of oncological patients increased whereas the number of emergency cases declined. The changes were thought to be related more to the transition in health and becoming a trauma center than to major developments in the country and the world.

2008-01-01

The aim of this study was to identify the classic autopsy signs of drowning in post-mortem multislice computed tomography (MSCT). Therefore, the post-mortem pre-autopsy MSCT- findings of ten drowning cases were correlated with autopsy and statistically compared with the post-mortem MSCT of 20 non-drowning cases. Fluid in the airways was present in all drowning cases. Central aspiration in either the trachea or the main bronchi was usually observed. Consecutive bronchospasm caused emphysema aquosum. Sixty percent of drowning cases showed a mosaic pattern of the lung parenchyma due to regions of hypo- and hyperperfused lung areas of aspiration. The resorption of fresh water in the lung resulted in hypodensity of the blood representing haemodilution and possible heart failure. Swallowed water distended the stomach and duodenum; and inflow of water filled the paranasal sinuses (100%). All the typical findings of drowning, except Paltau's spots, were detected using post-mortem MSCT, and a good correlation of MSCT and autopsy was found. The advantage of MSCT was the direct detection of bronchospasm, haemodilution and water in the paranasal sinus, which is rather complicated or impossible at the classical autopsy. (orig.)

1996-01-01

To differentiate fine hyperdense dots mimicking microcalcifications from true microcalcifications on mammography. Mammograms showing hyperdense dots in ten patients (mean age, 59 years) were evaluated. Two radiologists were asked to differentiate with the naked eye the hyperdense dots seen on ten mammograms and proven microcalcifications seen on ten mammograms. Densitometry was also performed for all lesions and the contrast index was calculated. The shape and distribution of the hyperdense dots were evaluated and enquires were made regarding any history of breast disease and corresponding treatment. Biopsies were performed for two patients with hyperdense dots. Two radiologists made correct diagnoses in 19/20 cases(95%). The contrast index was 0.10-0.88 (mean 0.58) for hyperdense dots and 0.02-0.45 (mean 0.17) for true microcalcifications. The hyperdense dots were finer and homogeneously rounder than the microcalcifications. Distribution of the hyperdense dots was more superficial in subcutaneous fat (seven cases) and subareolar area (six cases). All ten patients with hyperdense dots had history of mastitis and abscesses and had been treated by open drainage (six cases) and/or folk remedy (four cases). In eight patients, herb patches had been attached. Biopsies of hyperdense dots did not show any microcalcification or evidence of malignancy. These hyperdense dots were seen mainly in older patients. Their characteristic density, shape, distribution and clinical history makes differential diagnosis from true microcalcifications easy and could reduce unnecessary diagnostic procedures such as surgical biopsy

Six were men and six were women ; their average age was 41, and most were in their twenties. Lesions of the liver and spleen, as well as associated findings such as abdominal tuberculosis and other organ involvement of tuberculosis were analyzed. Results : There were three cases of hepatic tuberculosis, seven of splenic tuberculosis, and two of hepatosplenic involvement of tuberculosis. On the basis of the ultrasonographic and CT findings, hepatosplenic tuberculosis was classified as one of two patterns : miliary or micronodular, ormacronodular. The micronodular type was more common (9/12 cases) being characterized by innumerable micronodules,and with easy coalescence in the liver and spleen in five of the nine cases. The macronodular type of low density mass was noted in the other three patients. Splenomegaly was noted in 12 cases and hepatomegaly in ten. Pulmonary tuberculosis-including the miliary type(n=5)-was noted in eight patients. Associated abdominal tuberculosis such as lymphadenopathy with central low density and peripheral rim enhancement (n=6), tuberculous peritonitis(n=3),highly attenuated ascites(n=6), adrenal tuberculosis(n=1), renal tuberculosis(n=1), ovarian abscess(n=1), psoasabscess(n=1), and systemic tuberculosis such as central nervous system tuberculoma(n=2), cervical lymphadenopathy(n=4) and tuberculous spondylitis(n=1) were noted. Conclusion : Ultrasonography and CT were valuable in the detection and diagnosis of hepatosplenic tuberculosis

Reverse shoulder arthroplasty in young patient with achondroplasia - Ten year follow up: Case report.

Science.gov (United States)

van den Broek, M; Verborgt, O; Declercq, G

2017-11-01

Skeletal dysplasia in achondroplasia can affect all body joints - including the glenohumeral joint - and is prone to develop to degenerative osteoarthritis (OA). This may cause pain and mobility problems at young age. Surgical treatment is challenging due to the dysplastic anatomy of the shoulder joint - with a dysplastic deformed short humerus, a small, hypoplastic medialized glenoid and lateralized acromion - and the long life expectancy of these patients. The indications for reverse shoulder arthroplasty (RSA) evolved during years with rotator cuff tears and rotator cuff arthropathy in combination with or without glenohumeral OA as the main indicator, with good short to mid-term results. Long term results of RSA are rarely found in literature, especially in young patients. The use of a RSA in glenohumeral OA with an intact rotator cuff has rarely been reported. In this case report we present the ten-year clinical and radiographic results of a RSA for the treatment of degenerative OA with glenohumeral dysplasia in a young patient with achondroplasia.

Metastatic pulmonary calcification: high-resolution computed tomography findings in 23 cases

Directory of Open Access Journals (Sweden)

Luciana Camara Belém

Full Text Available Abstract Objective: The aim of this study was to evaluate the high-resolution computed tomography (HRCT findings in patients diagnosed with metastatic pulmonary calcification (MPC. Materials and Methods: We retrospectively reviewed the HRCT findings from 23 cases of MPC [14 men, 9 women; mean age, 54.3 (range, 26-89 years]. The patients were examined between 2000 and 2014 in nine tertiary hospitals in Brazil, Chile, and Canada. Diagnoses were established by histopathologic study in 18 patients and clinical-radiological correlation in 5 patients. Two chest radiologists analyzed the images and reached decisions by consensus. Results: The predominant HRCT findings were centrilobular ground-glass nodules (n = 14; 60.9%, consolidation with high attenuation (n = 10; 43.5%, small dense nodules (n = 9; 39.1%, peripheral reticular opacities associated with small calcified nodules (n = 5; 21.7%, and ground-glass opacities without centrilobular ground-glass nodular opacity (n = 5; 21.7%. Vascular calcification within the chest wall was found in four cases and pleural effusion was observed in five cases. The abnormalities were bilateral in 21 cases. Conclusion: MPC manifested with three main patterns on HRCT, most commonly centrilobular ground-glass nodules, often containing calcifications, followed by dense consolidation and small solid nodules, most of which were calcified. We also described another pattern of peripheral reticular opacities associated with small calcified nodules. These findings should suggest the diagnosis of MPC in the setting of hypercalcemia.

Document seasonality occurrence and epidemiologic characteristics of Cyclospora cayetanensis infections during a 10-year period from patients consulting at the University Hospital, Honduras. Retrospective non interventional hospital-based study analyzed laboratory results from the period 2002 to 2011 of fresh and Ziehl-Nielsen carbolfuchsin stained routine stool samples received for parasitologic examination. Sporadically a sample with numerous oocysts was allowed to sporulate in 2.5 % potassium dichromate confirming the presence of bi-cystic bi-zoic oocysts. A total of 35,157 fecal samples were examined during a ten-year span, of which a third (28.4 %) was stained by the Ziehl-Neelsen carbolfuchsin method diagnosing a total of 125 (1.3 %) C.cayetanensis infections. A statistically significant apparent seasonality was observed most years during May to August (range p < 0.036-0.001), with 83.3 % of 125 cases occurring in those rainy months. All C. cayetanensis cases came from urban poor neighborhoods; male/female relation was 1:1 except in 2006, when all patients were females (p = 0.05; r(2) = 22,448). Forty four point eight percent of the stool samples were diarrheic or liquid and 65.6 % infections were identified in children 10 years old or less. Enteric helminths and protozoa co-infected Cyclospora positive patients in 52 instances.: 8 % Ascaris lumbricoides, 8 % Giardia duodenalis, 23.2 % Blastocystis spp. and less frequently Entamoeba histolytica/E. dispar, Strongyloides stercoralis, and Trichuris trichiura. Results suggest a seasonal pattern for Cyclospora infections diagnosed in a clinical setting during the rainy months in Tegucigalpa and surrounding areas. Community studies should be conducted to support or dispute these observations.

Male breast cancer is very rare, with the incidence of 0.15-1% of all breast cancers and less than 1% of all cancers in men. The prognosis of male breast cancer is poorer than that of female because the median age of detection of the disease is in more late stage. It usually involves higher axillary lymph nodes. We report two case of male breast cancer to describe characteristic mammographic and ultrasonographic findings and to compare with the findings of gynaecomastia.

Mixed methods evaluation of targeted case finding for cardiovascular disease prevention using a stepped wedged cluster RCT

Directory of Open Access Journals (Sweden)

Marshall Tom

2012-10-01

Full Text Available Abstract Background A pilot project cardiovascular prevention was implemented in Sandwell (West Midlands, UK. This used electronic primary care records to identify untreated patients at high risk of cardiovascular disease then invited these high risk patients for assessment by a nurse in their own general practice. Those found to be eligible for treatment were offered treatment. During the pilot a higher proportion of high risk patients were started on treatment in the intervention practices than in control practices. Following the apparent success of the prevention project, it was intended to extend the service to all practices across the Sandwell area. However the pilot project was not a robust evaluation. There was a need for an efficient evaluation that would not disrupt the planned rollout of the project. Methods/design Project nurses will sequentially implement targeted cardiovascular case finding in a phased way across all general practices, with the sequence of general practices determined randomly. This is a stepped wedge randomised controlled trial design. The target population is patients aged 35 to 74, without diabetes or cardiovascular disease whose ten-year cardiovascular risk, (determined from data in their electronic records is ≥20%. The primary outcome is the number of high risk patients started on treatment, because these data could be efficiently obtained from electronic primary care records. From this we can determine the effects of the case finding programme on the proportion of high risk patients started on treatment in practices before and after implementation of targeted case finding. Cost-effectiveness will be modelled from the predicted effects of treatments on cardiovascular events and associated health service costs. Alongside the implementation it is intended to interview clinical staff and patients who participated in the programme in order to determine acceptability to patients and clinicians. Practical

Objective: To present the magnetic resonance (MR) imaging findings of 78 patients with meningiomas diagnosed in a single institution. Method: 78 patients with histological proven intracranial meningioma were studied. There were 52 female and 26 male patients (median=56 years). All MR imaging examinations were performed with 1.5-T MR imaging unit with standard protocol. The images were studied by two neuroradiologists, who reached the decisions regarding the findings by consensus. Results: Most of the tumors showed low signal on T1- (60%) and high signal on T2- (68%) and FLAIR (69%) weighted images. Also, the lesions showed heterogeneous signal on T1 (60%), T2 (68%) and FLAIR (64%) sequences. After contrast administration, 83% (n=65) of the tumors presented accentuated and 17% (n=13) showed moderate enhancement. The tumors were located in the frontal lobe in 44% of the cases, in the parietal lobe in 35%, the occipital lobe in 19% and the temporal lobe in 12% of the patients. Areas of vasogenic edema around the tumors were seen in 90% of the cases. Twenty six per cent of the cases showed bone infiltration, and the dural tail sign was seen in 59% of the tumors. Conclusion: Intracranial meningiomas usually show heterogeneous low signal on T1- and high signal on T2-weighted and FLAIR images, with intense enhancement after contrast administration. The frontal and parietal lobes are commonly affected. In addition, brain edema, dural tail sign and bone infiltration are the most frequent associated findings. (author)

Patient and public involvement (PPI) in studies carried out by the UK Medical Research Council Clinical Trials Unit (MRC CTU) at University College London varies by research type and setting. We developed a series of case studies of PPI to document and share good practice. We used purposive sampling to identify studies representing the scope of research at the MRC CTU and different approaches to PPI. We carried out semi-structured interviews with staff and patient representatives. Interview notes were analysed descriptively to categorise the main aims and motivations for involvement; activities undertaken; their impact on the studies and lessons learned. We conducted 19 interviews about ten case studies, comprising one systematic review, one observational study and 8 randomised controlled trials in HIV and cancer. Studies were either open or completed, with start dates between 2003 and 2011. Interviews took place between March and November 2014 and were updated in summer 2015 where there had been significant developments in the study (i.e. if the study had presented results subsequent to the interview taking place). A wide range of PPI models, including representation on trial committees or management groups, community engagement, one-off task-focused activities, patient research partners and participant involvement had been used. Overall, interviewees felt that PPI had a positive impact, leading to improvements, for example in the research question; study design; communication with potential participants; study recruitment; confidence to carry out or complete a study; interpretation and communication of results; and influence on future research. A range of models of PPI can benefit clinical studies. Researchers should consider different approaches to PPI, based on the desired impact and the people they want to involve. Use of multiple models may increase the potential impacts of PPI in clinical research.

An audit of toxicological analysis in Coronial autopsies performed at Forensic Science South Australia was conducted on the cases of three pathologists. Toxicological analysis had been performed in 555 (68 %) from a total of 815 autopsies. It was found that the proffered manner of death was changed from the provisional report (provided immediately after the post-mortem examination) in five cases (just under 1 %) as a consequence of the toxicological findings. This is a limited study as it is retrospective, not all cases had toxicological analysis and the findings are constrained by the range of the substances that could be detected. Nonetheless, the audit supports the application of toxicological analysis in medico-legal death investigation and suggests that an inclusive policy should be adopted.

The findings of the spinal MR imagings and the CT myelography of 5 cases with HTLV-I associated myelopathy (HAM) were presented. One case who showed transverse myelopathy with a multiple sclerosis-like abrupt onset showed spinal-cord swelling at the early stage on CT myelography; its disappearance was documented 4 months after corticosteroid therapy. The other 4 cases, all with slowly progressive myelopathy, clinically revealed spinal-cord atrophy, especially at the thoracic level, on MR imagings. The degree of spinal-cord atrophy seemed not have any correlation with the clinical and laboratory data or with the corticosteroid therapy. The clinical entity of HAM has not yet been determined, and its relationship with tropical spastic paraparesis (TSP) as well as that with some form of multiple sclerosis is controversial. The neuroradiological findings of MR imaging and CT myelography, including spinal-cord swelling at the early stage, in a case diagnosed as HAM with atypical clinical features or as spinal-cord atrophy in typical chronic cases might contribute to its resolution.

Objective: To investigate the characteristic clinical and X-ray findings of mycetoma and to enhance the understanding of mycetoma. Methods: The clinical and X-ray findings of mycetoma in 18 cases were analyzed with the review of literatures. There were 11 males and 7 females, the age ranged from 21-65 years, with the average of 41.5 year. The cases were all peasants, barefoot and with the history of trauma, which lasted for 4-17 years with the average of 9.8 year. Results: Sixty-seven lesions of bone in 18 cases (30 metatarsal, 20 cuneiform, 7 cuboid, 5 phalanx, 3 tibia, 2 calcaneus) were presented, including 8 rodent, 3 osteolytic, 3 cystic, 2 rodent and sclerosis changes, 2 sclerosis, 9 irregular thickened bony cortex, 7 irregular deleted bony cortex, 12 periosteal reaction, 3 irregular crest of bone in lesion, 13 rarefaction of bone cortex, 11 swimmy of surface arthrosis, 8 constriction of interval arthrosis, 2 spot calcification in the soft tissue, 2 sequestrum, and 2 soft tissue mass. The mycelium had been discovered in grain in 18 cases and the colour of grain was from brown to black. Conclusion: Mycetoma involves extensively and tends to involve multiple bones. The main X-ray findings are rodent and osteolytic changes

It is sometimes difficult to differentiate between a brain abscess and a tumor, for both show ring-enhancement on a CT scan. The present authors have studied the benefit of MRI for the differential diagnosis of these two lesions. The subjects of this study were 6 cases of brain abscess and 10 cases of brain tumor, all of them showing ring-enhancement on a CT scan. The MRI findings were compared with those of the CT scan taken at almost the same time, especially focussing on the difference in the ring-enhancement. In 5 out of the 6 cases of brain abscess, T 2 -weighted MRI demonstrated a comparatively thin and homogeneous low-intensity, round rim. In the cases of brain tumor, however, none of the cases demonstrated this typical low-intensity, round rim; rather, in them the rim was thick and irregular. The authors can conclude that those MRI findings can serve as important differential diagnostic findings between brain abscess and tumor; also, MRI may be used as a landmark for terminating the administration of antibiotics in cases of brain abscess.

Ten years of nuclear power

Energy Technology Data Exchange (ETDEWEB)

NONE

1964-08-15

Ten years have elapsed since the world's first nuclear power station began to supply electricity in Russia, and this in turn marked the end of a twelve year stage following the first controlled nuclear chain reaction at Chicago. These periods mark major stages in the development of atomic energy from the realm of abstract ideas to that of everyday industrial application. They followed a period of fundamental research and laboratory work, culminating in Enrico Fermi's demonstration of a system whereby the forces of the atom could be brought under control. Then it was necessary to find ways and means of using the chain reaction for practical purposes and on an industrial scale. And after this had been shown in 1954 to be technically possible, it had still to be developed into an economic process. The nuclear power station has proved itself from the technical and engineering standpoint. The third phase of development has been to bring it to the stage of being economically competitive with alternative sources of energy, and it would appear that we are now reaching that goal - though more slowly than had been envisaged ten years ago

Clinical findings in two cases of atypical scrapie in sheep: a case report

Directory of Open Access Journals (Sweden)

Chaplin Melanie

2007-02-01

Full Text Available Abstract Background Atypical scrapie is a recently recognised form of transmissible spongiform encephalopathy of sheep that differs from classical scrapie in its neuropathological and biochemical features. Most cases are detected in apparently healthy sheep and information on the clinical presentation is limited. Case presentation This report describes the clinical findings in two sheep notified as scrapie suspects and confirmed as atypical scrapie cases by immunohistochemistry and Western immunoblotting. Although both sheep displayed signs suggestive of a cerebellar dysfunction there was considerable variation in the individual clinical signs, which were similar to classical scrapie. Conclusion Any sheep presenting with neurological gait deficits should be assessed more closely for other behavioural, neurological and physical signs associated with scrapie and their presence should lead to the suspicion of scrapie.

Revesz syndrome is a variant of dyskeratosis congenita characterized by aplastic anemia, retinopathy, and central nervous system abnormalities. We describe a 3-year-old boy in whom the spectrum of neuroimaging findings, including intracranial calcifications, cerebellar hypoplasia and unusual brain lesions were found by biopsy to be gliosis despite their enhancement and progression. In patients with dyskeratosis-related syndromes, non-neoplastic parenchymal brain lesions occur and gliosis should be considered in the differential diagnosis for progressive enhancing brain lesions. Should this finding be confirmed consistently in additional cases, brain biopsy could potentially be avoided. (orig.)

The gagging reflex is a physiological reaction which safeguards the airway from foreign bodies. In some people this response is exaggerated to the extent that the acceptance/provision of dental treatment is not possible. The aim of this paper is to review the role of acupuncture in controlling gagging as a safe, cheap, quick and relatively non-invasive technique. Ten people agreed to try ear acupuncture to control gagging during dental treatment. Prior to treatment the severity of gagging was assessed. Acupuncture needles were inserted into a specific anti-gagging point on each ear, manipulated briefly and left in situ. Dental treatment was then carried out and the effectiveness of the acupuncture in preventing gagging was assessed. After treatment, the needles were removed and the patient discharged. All acupuncture was carried out by a dentist trained in its use. Four people had a severe gag reflex which made treatment impossible and six had a very severe reflex which made treatment impossible and affected their dental attendance. Ear acupuncture completely controlled the gag reflex in eight cases (23 treatment episodes) and partially controlled the reflex in two cases (two treatment episodes). Dental treatment could be carried out in all cases and at all visits. The cost of materials was 0.2 pounds per person per visit. Additional clinical time was in the order of 2-3 minutes. There were no adverse reactions to the technique and, on all occasions, patients were fit to leave the surgery and travel home unaccompanied. Ear acupuncture was successful in controlling the gag reflex. It is a safe, quick, inexpensive and relatively noninvasive technique. A controlled clinical trial is required to investigate any placebo effect.

Low back pain (LBP) affects a large proportion of the population. Transcutaneous electrical nerve stimulation (TENS) was introduced more than 30 years ago as an alternative therapy to pharmacological treatments for chronic pain. However, despite its widespread use, the effectiveness of TENS is still controversial. The aim of this systematic review was to determine the efficacy of TENS in the treatment of chronic LBP. We searched MEDLINE, EMBASE, PEDro and the Cochrane Controlled Trials Register up to June 1, 2000. Only randomized controlled clinical trials of TENS for the treatment of patients with a clinical diagnosis of chronic LBP were included. Abstracts were excluded unless further data could be obtained from the authors. Two reviewers independently selected trials and extracted data using predetermined forms. Heterogeneity was tested with Cochran's Q test. A fixed effects model was used throughout for continuous variables, except where heterogeneity existed, in which case, a random effects model was used. Results are presented as weighted mean differences (WMD) with 95% confidence intervals (95% CI), where the difference between the treated and control groups was weighted by the inverse of the variance. Standardized mean differences (SMD) were calculated by dividing the difference between the treated and control by the baseline variance. SMD were used when different scales were used to measure the same concept. Dichotomous outcomes were analyzed with odds ratios. Five trials were included, with 170 subjects randomized to the placebo group receiving sham-TENS and 251 subjects receiving active TENS (153 for conventional mode, 98 for acupuncture-like TENS). The schedule of treatments varied greatly between studies ranging from one treatment/day for two consecutive days, to three treatments/day for four weeks. There were no statistically significant differences between the active TENS group when compared to the placebo TENS group for any outcome measures

To decrease the negative appendectomy rate in children, knowledge of the misleading imaging findings on US and CT in negative appendicitis cases is important. To evaluate the negative appendectomy rate and describe the imaging findings of US and CT that lead radiologists to misdiagnose acute appendicitis in children. From 2007 to 2013, 374 children operated for suspected appendicitis were proved to either have acute appendicitis (n = 348) or to be negative for appendicitis (n = 26) on pathological reports. Negative appendectomy rates were compared among imaging modalities, age groups and genders. We retrospectively reviewed US and CT findings from negative appendectomy cases. The overall negative appendectomy rate was 7.0% (26/374). There were no statistically significant differences among the subgroups. The most common misleading presentations on US were sonographic tenderness (9/16, 56%) and non-compressibility (9/16, 56%). The most common misleading finding on CT were the presence of an appendicolith or hyperdense feces (5/12, 42%). Periappendiceal fat inflammation was observed in only one case of negative appendicitis on US and on CT. Radiologists can misdiagnose children with equivocal diameters of appendices as having acute appendicitis when sonographic tenderness or non-compressibility is present on US and when an appendicolith or hyperdense feces is noted on CT. The possibility of negative appendicitis should be borne in mind when periappendiceal fat inflammation is absent or minimal in indeterminate cases. (orig.)

Sacral agenesis (or caudal regression syndrome) is a rare congenital anomaly involving various levels of coccygeal, sacral, and even lumbar or lower thoracic vertebral dysgenesis, as well as spinal cord abnormalities. A few cases have been previously reported in Korea, especially based upon MRI findings. We describe a case of a 4-year-old girl with partially bilateral agenesis of the sacrum (type II), and club-shaped (chisel-shaped) spinal cord disruption. We also review MRI findings of sacral agenesis, focused on classification and radiological findings.

2001-06-01

Full Text Available In the past ten years, 45 cases of infantile spasm treated in our center. From these patients, 15 cases received only steroid, other 15 cases only clonazepam, and the rest, a combination of clonazepam and steroid. All patients were observed for two years. This is a retrospective study, the data being extracted from patients record. A number of patients were treated in ambulatory and the others were patients of the hospital. The result of comparison of optimal control of seizures are as follow: 1 In only steroid group 27 percent of the patients were free of seizure, 2 In only clonazepam group 28 percent showed no seizure, 3 in combined clonazepam and steroid group 39% were seizure-free. Based on this trial we believe that treatment of infantile spasm with combined steroid and clonazepam is better than any of them alone. Considering these results, we believe that the treatment of infantile spasm with a combination of steroid and clonazepam is preferable to these drugs.

To evaluate the CT and MRI findings of neurosyphilis. We retrospectively reviewed the CT and MR imaging findings in five patients with intracranial neurosyphilis confirmed by CSF, VDRL, TPHA, and clinical follow-up. MR imaging was performed in all five cases, and CT in two. The MRI and CT findings of intracranial neurosyphilis included infarction (n=3), focal inflammation (n=1) and encephalopathy (n=1). There was a total of ten infaretions : three of the basal ganglia, two each of the frontal lobe, watershed zone, and cerebellum, and one of the occipital lobe. Intaretion was most common in MCA territory (n=9; 50%), followed by the watershed zone (16.6%), posterior cerebral artery territory (16.6%), and posterior inferior cerebellar artery territory (11.1%). The size of the lesion varied from 1cm to larger than one lobe. One patient showed diffuse high signal intensity in the left temporal lobe, but on follow-up MRI, this had resolved. The most common finding of neurosyphilis, as seen on MRI and CT, was infarction in middle cerebral arterial territory

The concentrations and isotopic composition of noble gases have been determined in all ten stone meteorites recovered in Antarctica during 1976-1977 by a U.S.-Japanese expedition. From a comparison of spallogenic and radiogenic gas components it is concluded that the chondrites Mt. Baldr (a) and Mt. Baldr (b) belong to the same fall but that all other stone meteorites are individual finds. (orig.)

Although there is a large increase in investment for tuberculosis control in Myanmar, there are few operational analyses to inform policies. Only 34% of nationally reported cases are from women. In this study, we investigate sex differences in tuberculosis diagnoses in Myanmar in order to identify potential health systems barriers that may be driving lower tuberculosis case finding among women. From October 2014 to March 2015, we systematically collected data on all new adult smear positive tuberculosis cases in ten township health centres across Yangon, the largest city in Myanmar, to produce an electronic tuberculosis database. We conducted a descriptive cross-sectional analysis of sex differences in tuberculosis diagnoses at the township health centres. We also analysed national prevalence survey data to calculate additional case finding in men and women by using sputum culture when smear microscopy was negative, and estimated the sex-specific impact of using a more sensitive diagnostic tool at township health centres. Overall, only 514 (30%) out of 1371 new smear positive tuberculosis patients diagnosed at the township health centres were female. The proportion of female patients varied by township (from 21% to 37%, p = 0.0172), month of diagnosis (37% in February 2015 and 23% in March 2015 p = 0.0004) and age group (26% in 25-64 years and 49% in 18-25 years, p Myanmar, found that substantially fewer women than men were diagnosed in all study townships. The sex ratio of newly diagnosed cases varied by age group, month of diagnosis and township of diagnosis. Low sensitivity of tuberculosis diagnosis may lead to a potential under-diagnosis of tuberculosis among women.

Objective: To analyze the CT findings of extrahepatic alveolar echinococcus (EAE), and assess the value of CT scanning for the diagnosis of such cases. Methods: 12 patients with hepatic alveolar echinococcus (HAE) verified by operation and histology were examined by CT because of new complains. It was found that multiple organs were involved by the same lesions. Results: Brain AE (7 cases) showed single or multiple cerebral nodules, characterized by honeycombed hypodense structures or target sign after enhancement. Lung AE (3 cases) appeared as irregular, peripherally scattered nodules, with small vacuoles or cavities inside. The only 1 case with heart AE demonstrated a multiple calcifications and vacuoles within the mass. Adrenal gland AE (2 cases) presented as plaques containing different sizes of hypodense areas and calcifications. Retroperitoneal AE (2 cases) exhibited mass with plentiful calcifications. Conclusion: CT can define the location and morphology of the lesion, providing a reliable method for the diagnosis and treatment of the disease

Is TENS purely a placebo effect? A controlled study on chronic low back pain.

Marchand, S; Charest, J; Li, J; Chenard, J R; Lavignolle, B; Laurencelle, L

1993-07-01

Although high-frequency low-intensity transcutaneous electric nerve stimulation (TENS) has been extensively used to relieve low back pain, experimental studies of its effectiveness have yielded contradictory findings mainly due to methodological problems in pain evaluation and placebo control. In the present study, separate visual analog scales (VAS) were used to measure the sensory-discriminative and motivational-affective components of low back pain. Forty-two subjects were randomly assigned to 1 of 3 groups: TENS, placebo-TENS, and no treatment (control). In order to measure the short-term effect of TENS, VAS pain ratings were taken before and after each treatment session. Also, to measure long-term effects, patients rated their pain at home every 2 h throughout a 3-day period before and 1 week, 3 months and 6 months after the treatment sessions. In comparing the pain evaluations made immediately before and after each treatment session, TENS and placebo-TENS significantly reduced both the intensity and unpleasantness of chronic low back pain. TENS was significantly more efficient than placebo-TENS in reducing pain intensity but not pain unpleasantness. TENS also produced a significant additive effect over repetitive treatment sessions for pain intensity and relative pain unpleasantness. This additive effect was not found for placebo-TENS. When evaluated at home, pain intensity was significantly reduced more by TENS than placebo-TENS 1 week after the end of treatment, but not 3 months and 6 months later. At home evaluation of pain unpleasantness in the TENS group was never different from the placebo-TENS group.(ABSTRACT TRUNCATED AT 250 WORDS)

To evaluate the ultrasonographic appearance of fibroadenomatoid hyperplasia of the breast. We retrospectively reviewed US findings including size, shape, border, boundary echo, internal echo, posterior echo, lateral echo, and transverse/anteroposterior diameter of 19 patients (mean age 36.6 years) with pathologically proven fibrodenomatoid hyperplasia. Mammogramas were available in 18 patients. On US size, shape, border, internal echo, boundary echo, posterior echo, lateral echo, the ratio of transverse to anteroposterior diameter were analyzed by two radiologist in agreement. Fifteen of 19 patients presented with palpable masses. On US, the mean size of the masses was 13 mm (range, 4-26 mm). The shape of lesions were round to oval in 10 cases (53%), lobulated in 6 cases (32%), irregular in 3 cases (15%). The borders of the lesions were sharp-well defined in 11 cases (58%), unsharp-ill defined in 8 cases (42%). Fourteen cases(74%) showed fine homogeneous internal echo and 5 cases (26%) showed coarse heterogeneous internal echo. Nonexistent or regular fine boundary echo was shown in 11 cases (58%) and irregular thick boundary echo was shown in 8 cases (42%).Posterior sonic enhancement was shown in 10 cases (53%), posterior sonic shadowing in 6 cases (32%). And three cases (15%) showed no posterior echo. Marked lateral echo was demonstrated in 11 cases (58%). The transverse/anteroposterior diameter ratio ranged between 1.0 and 1.5 in 1 case (5.5%), below 1.0 in 1 case (5.5%), and above 1.5 and 17 cases (89%). Mammogram showed no abnormality in ten patients with dense breast, mass like density in seven patients, and clustered microcalcification in one patient. Fibroadenomatoid hyperplasia was usually presented in fourth decade as a palpable breast mass and common US findings were similar to fibroadenoma. However, histopathologic confirmation was needed for the diagnosis because fibroadenomatoid hyperplasia sometimes showed the US features of malignancy.

To describe the MRI findings of trigeminal neurinoma. We retrospectively analyzed the MRI findings of 19 patients with trigeminal neurinomas proven by surgery and pathologic examination. Axial T1- and T2-weighted MR images in all patients and gadolinium-enhanced T1-weighted images in 14 patients were obtained at 2.0T(8 cases), 1.5T(6 cases) or 0.5T(5 cases). These were analyzed in terms of tumor size, signal intensity, degree of contrast enhancement, the presence or absence of cystic change and denervation atrophy of the masticator muscles. Clinical manifestations included sensory abnormality or pain(n=12), headache(n=10), impaired visual acuity or diplopia(n=6), hearing loss or tinnitus(n=3), weakness of masticator muscles(n=2), and mass or nasal obstruction(n=2). On MR images, tumor size was seen to average 4.2(range 1.5-6)cm;tumors were located in the posterior cranial fossa(n=8), middle cranial fossa(n=4), ophthalmic nerve(n=2), maxillary nerve(n=1), and mandibular nerve(n=1), and in three cases were dumbbell-shaped and extended into both the middle and posterior cranial fossa. On T1-weighted images, signals were isointense with cortical grey matter, in ten cases(53%), and of low intensity in nine (47%);on T2-weighted images, signals were of high intensity in 15cases(79%) and were isointense in four (21%). Cystic change was seen in 12 cases(63%). After enhancement, all (14/14) the tumors enhanced. Denervation atrophy was seen in nine cases(47%) and all of these involved the trigeminal ganglion or mandibular nerve. A trigeminal neurinoma shows similar signal intensity and enhancement to other cranial neurinomas with a higher incidence of cystic degeneration. Its location and shape are characteristic, and where there is involvement of the trigeminal ganglion or mandibular nerve, denervation atrophy may be seen

Esophageal schwannomas are a relative rare benign neoplasm that usually occurs in the upper esophagus, in the middle aged women. We report a case of a 67-year-old man with a lower esophageal schwannoma. This lesion was composed of homogenous density, iso-attenuating with the chest wall muscle on pre- and post-contrast chest computed tomography (CT). The CT findings of the esophageal schwannoma are similar to those of esophageal leiomyoma. Hense, esophageal schwannoma may be a differential diagnosis with esophageal leiomyoma.

Magnetic resonance imaging findings in primary lymphoma of the liver: a case report

Full Text Available Abstract Introduction Primary lymphoma of the liver is an extremely rare finding, with the few such cases reported in the literature to date describing indeterminate imaging findings, being focused more on computed tomography. To the best of our knowledge, there is no prior report describing magnetic resonance imaging scan findings with such a lesion. In the case reported here, magnetic resonance imaging gave us the opportunity to ascertain the correct diagnosis, confirmed by histopathology, thus avoiding unnecessary surgery or other treatments. Although this condition is rare, knowledge of magnetic resonance imaging findings will be invaluable for radiologists and other medical subspecialties that may face such cases in the future in helping to provide adequate management for affected patients. Case presentation A focal lesion was incidentally detected by ultrasound in a 75-year-old asymptomatic Albanian man being treated for benign hypertrophy of prostate. Chest and abdomen computed tomography scans did not reveal any abnormal findings besides a solid focal lesion on the right lobe of the liver and a mild homogenous enlargement of the prostate gland. Subsequently, magnetic resonance imaging of the upper abdomen was performed for better characterization of this lesion. Our patient was free of symptoms and his laboratory test results were normal. Conclusions The magnetic resonance imaging scan results showed some distinctive features that helped us to make the correct diagnosis, and were thus very important in helping us provide the correct treatment for our patient.

There are no guidelines addressing the public health aspects of methanol poisoning during larger outbreaks. The current study was done to discuss the role of active case finding and a national guideline that organizes all available resources according to a triage strategy in the successful management of a methanol mass poisoning in Rafsanjan, Iran, in May 2013. A retrospective cross-sectional study was performed reviewing the outbreak Emergency Operation Center files. The objectives were to describe the characteristics, management and outcome of a methanol outbreak using Active Case Finding to trace the victims. A total of 694 patients presented to emergency departments in Rafsanjan after public announcement of the outbreak between 29th May and 3rd June 2013. The announcement was mainly performed via short message service (SMS) and local radio broadcasting. A total of 361 cases were observed and managed in Rafsanjan and 333 were transferred to other cities. Seventy-five and 100 patients underwent hemodialysis (HD), retrospectively. The main indication for HD was refractory metabolic acidosis. Eight patients expired due to the intoxication. Except for the deceased cases, no serum methanol level was available. In developing countries, where diagnostic resources are limited, use of active case finding and developing national guidelines can help in the management of large outbreaks of methanol poisonings. © The Author 2014.

1998-01-01

The purpose of this study is to investigate the CT findings of acute right colonic diverticulitis, and to determine the difference between these and published reports describing left colonic, especially sigmoid, diverticulitis. Inflamed diverticula were visible in all cases, and were solitary. Nine cases occurred in the ascending colon and four in the cecum; in particular, eleven occurred around the ileocecal valve. In three cases, the inflamed diverticulum was less than 1 cm in diameter; in five cases, 1-2 cm; in three, 2-3 cm, and in two, 3-4 cm. These were able to be classified into two major forms. In three cases it was nodular with hyperattenuation and some inhomogeneity, and ten shows the target form with thick walls and a central cavity. In five of these target lesions, the wall pattern was partially or completely inhomogeneous, or multilayered. The material filling the central cavity were gas in five cases, fecalith in two, and fluid in three. Abnormal pericoloic fat infiltrations were seen in twelve cases (92%), segmental colonic wall thickening in eleven (85%), other not-inflamed diverticula in five (38%), mesenteric lymph node enlargement in three (23%), free pericecal fluid collection in three (23%), and perirenal fascial thickening in two (15%). The complications such as remote abscess cavity, colonic obstruction, fistula or perforation were not found. On barium colon study, diverticulitis was in all cases confirmed by the presence of barium in the deformed diversiculum. Among CT findings for acute right colonic diverticulitis, the most important and pathognomonic is inflamed diverticula; the forms of these vary, and include gangrenous diverticulitis. The CT findings of early right colonic diverticulitis in Koreans might not, however, reveal the complications which sigmoid diverticulitis frequently involves; in patients with right lower quadrant pain imaging studies are performed promptly, and for the mesentery, the anatomical base between right and

Brachialis periosteal avulsion injury is an uncommon injury occurring in young children. The injury may be misinterpreted or overlooked because of misleading or subtle radiological findings. A case of 7-year-old child with post-traumatic elbow pain and subtle findings on elbow radiography is presented. The injury was initially misinterpreted as an avulsion fracture of the medial epicondyle. Following radiological review, a diagnosis of brachialis periosteal avulsion injury was made. The radiographic and magnetic resonance imaging (MRI) findings of this injury are presented to stress the value of comparing the radiographic findings with previous imaging and to increase awareness of this uncommon injury.

The purpose of this study is to evaluate radiologic findings of rhabdomyosarcoma of children in the head and neck concerning the origin, morphologic characteristics, extent, and the route of intracranial extension on CT and MR. Twenty cases of pathologically proven rhabdomyosarcoma were analyzed. Fifteen CT scans (postcontrast CT (n=13), precontrast CT (n=2)) and eleven MR scans were obtained. Postcontrast MR scans were performed in the ten cases. Six cases had CT and MR scans. Nine cases had only CT scan and five had only MR scans. We retrospectively analyzed the origin, morphologic characteristics (attenuation, signal intensity, margin), extent,intracranial extension, route and clinical staging of rhabdomyosarcoma on CT and MR scans. Rhabdomyosarcoma of children in the head and neck tends to show relatively severe bony destruction of skull base and various intracranial extension routes can be helpful radiologic findings on the CT or MR scan although its CT density or signal intensity of MR was not specific. And it is peculiar that infratempral fossa was the most common site of origin of rhabdomyosarcoma. (author). 28 refs., 2 tabs., 5 figs

Tahan, Hussein A

2002-01-01

The use of case management plans has contained cost and improved quality of care successfully. However, the process of developing these plans remains a great challenge for healthcare executives, in this article, the author presents the answer to this challenge by discussing a 10-step formal process that administrators of patient care services and case managers can adapt to their institutions. It also can be used by interdisciplinary team members as a practical guide to develop a specific case management plan. This process is applicable to any care setting (acute, ambulatory, long term, and home care), diagnosis, or procedure. It is particularly important for those organizations that currently do not have a deliberate and systematic process to develop case management plans and are struggling with how to improve the efficiency and productivity of interdisciplinary teams charged with developing case management plans.

Medulloblastoma is a brain tumor of neuro epithelial origin, which represents 15 to 30% of all pediatric brain tumors, and less than 1% of CNS adult neoplasms. We report the imaging findings of 8 adult patients with medulloblastoma. The mean age was 35 years, ranging from 20 to 65 years, and the male:female rate was 3:5. The tumors were predominantly lateral (63%), hyperdense on CT scans (83%), and on the MRI, hypointense on T1 (100%) and hyperintense on T2 (80%) weighted images. It was seen intratumoral necrosis and cysts in six cases and calcifications in three. Hydrocephalus was observed in 5 cases and brain stem invasion in four. The imaging findings of medulloblastomas in adults are different of those in child, and also nonspecific. Although these tumors are uncommon in adults, they must be considered in the differential diagnosis of cerebellar masses in the posterior fossa of this age group. (author)

Full Text Available Objective. Patients with intraocular foreign bodies were retrospectively analyzed. Population characteristics, pathogenic factors, and the outcomes during the past ten years were discussed. Design. Retrospective case series study. Method. Medical records of 1340 patients hospitalized in Beijing Tongren Hospital from January 1, 2004, to December 31, 2013, were collected. Results. Average age was 33.0 ± 13.8 (1–76 years old in 1340 patients. There were more males (1270, 94.8% than females (70, 5.2%. Patients from outside of Beijing (82.1%, n=1100 prevailed. Farmers (32.1%, n=430 and workers (22.3%, n=299 were the top two affected professions. Leading two causes were splashing of foreign bodies (SFB (58.6%, n=785 and explosives (31.8%, n=426. More males than females were injured by SFB (59.4% versus 44.3%, P=0.009. Firework injury was the commonest (41.6% versus 3.1%–15.3%, P<0.05 in patients under nine. The annual percentages in patients over 50 increased (P<0.001 and in patients by explosives decreased (P=0.027. Conclusion. Most patients in this study were young males from outside of Beijing and farmers. SFB accounted most for patients over 10 years old and fireworks for those under ten. Patients over 50 increased while those by explosives decreased annually over the period.

Dengue, also known as break-bone fever, is a tropical disease transmitted by mosquitoes. If the similarity between dengue infected users can be identified, it can help government's health agencies to manage the outbreak more effectively. To find similarity between cases affected by Dengue, user's personal and health information are the two fundamental requirements. Identification of similar symptoms, causes, effects, predictions and treatment procedures, is important. In this paper, an effective framework is proposed which finds similar patients suffering from dengue using keyword aware domain thesaurus and case base reasoning method. This paper focuses on the use of ontology dependent domain thesaurus technique to extract relevant keywords and then build cases with the help of case base reasoning method. Similar cases can be shared with users, nearby hospitals and health organizations to manage the problem more adequately. Two million case bases were generated to test the proposed similarity method. Experimental evaluations of proposed framework resulted in high accuracy and low error rate for finding similar cases of dengue as compared to UPCC and IPCC algorithms. The framework developed in this paper is for dengue but can easily be extended to other domains also.

We analyzed the sonograms of 6 cases with uterine synechiae in pregnancy. The diagnosis was based on the clinical and sonographic findings. Previous curret age during the artificial abortion and/or after the spontaneous abortion had been done in 5 cases (83.3%). In all cases, uterine synechia in pregnancy was recognized asintra-amniotic sheet containing hypoechoic central zone and an hyperechoic outer layers. Y-shaped splitting of thehyperechoic outer layers was seen against the uterine wall. The placenta extended along the sheet in 4 cases. Uterine synechiae in pregnancy should be distinguished from amniotic band syndrome by the characteristic snographic findings, and unwarranted abortion of normal fetus should be avoided

Full Text Available Lipomas are common soft tissue tumors of mesenchymal origin.They contain mature adipose tissue. They are usually located in the subcutaneous tissue. They rarely ocur within the muscle and then are called intramuscular lipomas. Ultrasonography is the first diagnostic method to be selected. However, cross-sectional imaging methods are more useful in the diagnosis. On Magnetic resonance imaging (MRI, with the help of signal characteristics and fat suppression techniques,diagnosis is easily achieved. In addition, the relationship of lesion with the adjacent anatomical structures can be assessed better with MRI. Here, will be explained two different intramuscular lipoma cases and imaging findings will be reviewed. [J Contemp Med 2016; 6(3.000: 221-225

To study and characterise the MR imaging findings of lesions of the anterior interosseous nerve (AIN). Magnetic resonance imaging (MRI) findings of the forearm of ten patients referred to our institution with suspected AIN lesions were retrospectively studied. Five healthy volunteers with normal forearm MRI findings formed a control group. Two musculoskeletal radiologists assessed the forearm musculature for oedema in the distribution of the AIN, median, posterior interosseous and radial nerves on T2-weighted (T2W) fat-saturated sequences. T1-weighted (T1W) images were assessed and graded for the presence of muscle atrophy and fatty involution. Six patients had undergone surgical exploration; five of these had surgically confirmed AIN compression. Four patients had diagnoses other than AIN compression made on imaging features. Of the cases of proven AIN compression, oedema within the pronator quadratus (PQ) muscle was identified in all cases. PQ atrophy and fatty involution were seen in three (43%) surgically confirmed cases. Cases 2 and 3 also demonstrated oedema in the flexor digitorum profundus (FDP)1 and FDP2 muscles. These cases also showed oedema in the flexor-carpi radialis (FCR) and FDP3/FDP4 muscles, respectively. The four cases of non-AIN compression demonstrated muscle oedema patterns that were atypical for the AIN distribution. They included a rupture of the flexor pollicis longus (FPL) tendon, brachial neuritis, amyotrophic lateral sclerosis and compression of the proximal median nerve. MRI is a useful investigation in the diagnostic workup of AIN syndrome. AIN syndrome is likely when there is diffuse oedema of AIN innervated muscles on T2W fat-saturated images. The most reliable sign of an AIN lesion is oedema within the PQ. Oedema in the flexor carpi radialis, FDP3 and FDP4, although not in the classical distribution of the AIN, does not preclude the diagnosis of AIN syndrome. (orig.)

Full Text Available Just over 10 years ago, we conducted a culture study of the Computer Science Department at the flagship University of Illinois at Urbana-Champaign, one of the top five computing departments in the country. The study found that while the department placed an emphasis on research, it did so in a way that, in conjunction with a lack of communication and transparency, devalued teaching and mentoring, and negatively impacted the professional development, education, and sense of belonging of the students. As one part of a multi-phase case study spanning over a decade, this manuscript presents preliminary findings from our latest work at the university. We detail early comparisons between data gathered at the Department of Computer Science at the University of Illinois at Urbana-Champaign in 2005 and our most recent pilot case study, a follow-up research project completed in 2016. Though we have not yet completed the full data collection, we find it worthwhile to reflect on the pilot case study data we have collected thus far. Our data reveals improvements in the perceptions of undergraduate teaching quality and undergraduate peer mentoring networks. However, we also found evidence of continuing feelings of isolation, incidents of bias, policy opacity, and uneven policy implementation that are areas of concern, particularly with respect to historically underrepresented groups. We discuss these preliminary follow-up findings, offer research and methodological reflections, and share next steps for applied research that aims to create positive cultural change in computing.

Discovery and Use of Online Learning Resources: Case Study Findings

Full Text Available Much recent research and funding have focused on building Internet-based repositories that contain collections of high-quality learning resources, often called ‘learning objects.’ Yet little is known about how non-specialist users, in particular teachers, find, access, and use digital learning resources. To address this gap, this article describes a case study of mathematics and science teachers’ practices and desires surrounding the discovery, selection, and use of digital library resources for instructional purposes. Findings suggest that the teacher participants used a broad range of search strategies in order to find resources that they deemed were age-appropriate, current, and accurate. They intended to include these resources with little modifications into planned instructional activities. The article concludes with a discussion of the implications of the findings for improving the design of educational digital library systems, including tools supporting resource reuse.

To analyze the characteristics of CT and MRI findings of facial nerve schwannoma in ten patients. Ten patients with pathologically confirmed facial nerve schwannoma, underwent physical and radilolgic examination. The latter involved MRI in all ten and CT scanning in six. We analyzed the location (epicenter), extent and number of involved segments of tumors, tuumor morphology, and changes in adjacent bony structures. The major symptoms of facial nerve schwannoma were facial nerve paralysis in seven cases and hearing loss in six. Epicenters were detected at the intraparotid portion in five cases, the intracanalicular portion in two, the cisternal portion in one, and the intratemporal portion in two. The segment most frequently involved was the mastoid (n=6), followed by the parotid (n=5), intracanalicular (n=4), cisternal (n=2), the labyrinthine/geniculate ganglion (n=2) and the tympanic segment (n=1). Tumors affected two segments of the facial nerve in eight cases, only one segment in one, and four continuous segments in one. Morphologically, tumors were ice-cream cone shaped in the cisternal segment tumor (1/1), cone shaped in intracanalicular tumors (2/2), oval shaped in geniculate ganglion tumors (1/1), club shaped in intraparotid tumors (5/5) and bead shaped in the diffuse-type tumor (1/1). Changes in adjacent bony structures involved widening of the stylomastoid foramen in intraparotid tumors (5/5), widening of the internal auditary canal in intracanalicular and cisternal tumors (3/3), bony erosion of the geniculate fossa in geniculate ganglion tumors (2/2), and widening of the facial nerve canal in intratemporal and intraparotid tumors (6/6). The characteristic location, shape and change in adjacent bony structures revealed by facial schwannomas on CT and MR examination lead to correct diagnosis.

To investigate vocal quality variability after applying tongue trills associated with transcutaneous electrical nerve stimulation (TENS) on the larynx of women with normal laryngeal function. Additionally, to verify the effect of this technique over time on voice quality. Participants were 40 women (average 23.4 years) without vocal complaints. The procedure involved tongue trills with or without TENS for 3 minutes, rest and repeating the technique for another 2 minutes. The participants' voices were recorded before (Pre), after three minutes (Post 3min) and after two additional minutes (Post 5min) applying the technique. TENS with two electrodes was used on the thyroid cartilage. Self-assessment, acoustic and perceptual analysis were performed. When comparing tongue trills in isolation and associated with TENS, a greater sense of stability in phonation (self-assessment) and improvement in voice quality (perceptual evaluation) was observed in the combination technique. There was no statistical difference in acoustics findings between tongue trills in isolation and associated with TENS. When comparing the time effect of tongue trills with TENS in self-assessment there was a perception of less muscle tension (3min) and greater comfort during phonation (5 min); in the acoustic analysis, there was an increase of F0 (3 and 5 min) and intensity (5 min) when compared to Pre-moment; in the perceptual evaluation, better voice quality (3min). Comparing tongue trills in isolation and associated with TENS, there were changes in the comfort and muscle tension perception, as well as in vocal quality. On the other hand, tongue trills associated with TENS performed in 3 or 5 minutes resulted in beneficial effects on the voice identified in the assessments.

This multicenter study assessed the feasibility of conducting a phase III trial of transcutaneous electrical nerve stimulation (TENS) in patients with cancer bone pain recruited from palliative care services. Eligible patients received active and placebo TENS for 1 hour at site of pain in a randomized crossover design; median interval between applications 3 days. Responses assessed at 30 and 60 minutes included numerical and verbal ratings of pain at rest and on movement, and pain relief. Recruitment, tolerability, adverse events, and effectiveness of blinding were also evaluated. Twenty-four patients were randomised and 19 completed both applications. The intervention was well tolerated. Five patients withdrew: 3 due to deteriorating performance status, and 2 due to increased pain (1 each following active and placebo TENS). Confidence interval estimation around the differences in outcomes between active and placebo TENS suggests that TENS has the potential to decrease pain on movement more than pain on rest. Nine patients did not consider that a placebo was used; the remaining 10 correctly identified placebo TENS. Feasibility studies are important in palliative care prior to undertaking clinical trials. Our findings suggest that further work is required on recruitment strategies and refining the control arm before evaluating TENS in cancer bone pain. Cancer bone pain is common and severe, and partly mediated by hyperexcitability. Animal studies suggest that Transcutaneous Electrical Nerve Stimulation can reduce hyperalgesia. This study examined the feasibility of evaluating TENS in patients with cancer bone pain in order to optimize methods before a phase III trial. Copyright 2010 American Pain Society.

Hydatid disease is caused by Echinococcus granulosus. The most common locations for hydatid cysts are lung and liver. The central nervous system is involved in only 2% of cases, and these cysts are usually located in the brain parenchyma. Primary involvement of the bones of the skull is very uncommon. We report the case of a child with cranial echinococcosis which presented in the form of an osteolytic lesion with an extradural cyst. This was the unique feature of the disease. The CT and MR findings are described. This presentation has rarely been reported in the literature. (Author) 5 refs

Subacute necrotizing myelopathy(SNM) is a rare non-tumorous disease of spinal cord characterized by subacute clinical course of progressive neurological deterioration. We report MR findings of a patient with pathologically proved SNM. 1 case of pathologically proved subacute necrotizing myelopathy. The patients was a 56-year-old man with progressive motor weakness and sensory loss of the lower extremities, and urinary and fecal incontinence for 11 months. Spine MRI revealed diffuse enlargement of the thoracic spinal cord from T2 to T7 level. Signal intensity of the expanded spinal cord was isointense relative to normal cord on T1-weighted image and hyperintense on proton-density and T2-weighted images. On contrast enhanced T1-weighted image, there was diffuse homogeneous enhancement in the expanded cord lesion. MR demonstration of stable persistence of spinal cord lesion or atrophy over months or years with clinical findings of gradual progressive neurologic deterioration may be helpful in the diagnosis of SNM

Computed tomography (CT) was used to evaluate 57 patients with Minamata disease (methylmercury poisoning); it was proved to be an objective and practical screening procedure. A typical patient who presented an acute onset of concentric constriction of visual fields and cerebellar ataxia showed a low-density area in both occipital regions; cerebellar atrophy and enlarged cerebral cortical sulci. On the other hand, the majority of patients who presented a chronic onset, with only a mild concentric constriction of visual fields, dysdiadochokinesis, and sensory disturbance showed only a questionable or a mild cerebellar atrophy. An enlarged paracerebellar space in mild cerebellar atrophy was easily identified at the pontine angle cistern, the paravermian cistern, and the triangular space of the rectal sinus in the coronal section on an enhanced CT scan. These findings were compatible with pathological findings of mild cases of Minamata disease. The correlation of dysdiadochokinesis with the degree of cerebellar atrophy was demonstrated. (author)

Gastric antral vascular ectasia (watermelon stomach) is characterized by a prominent longitudinal erythematous fold of gastric antrum. Because it has usually been diagnosed by gastroscopy and biopsy, its radiologic findings have not been well described. We report a case of gastric antral vascular ectasia, and describe its findings, as seen on UGIS, ultrasonography, and computed tomography.

Solano Urrutia, Antonio Luis; Gallon, Luis Alfonso; Echandia, Carlos

2003-01-01

Femoral shaft fractures are a common and temporarily disabling injury in children. Recent advances in orthopedic traumatology have led us at the Hospital Universitario del Valle, in Cali, Colombia, to perform a case series observational study with the use of a more aggressive approach with the new endomedullar titanium nails (TENs) in children suffering femur shaft fractures, in a closed procedure performed under image intensification. The main purpose of this study was to evaluate the outcome of 30 children treated with these nails. Pediatric femoral shaft fractures are more common in males with approximately a 2.75:1 male to female ratio. The age distribution is bimodal, with peaks in the younger than 5 years and mid-teenage groups (10-14 years) because of the increased incidence of high-energy trauma in teenage children (mean age: 9 years). Overall, TENs allowed rapid mobilization with few complications. The results were excellent or satisfactory in our cases. No child lost rotational alignment in the postoperative period. Irritation of the soft tissue near the knee by the nail tip occurred in one patient. As indications, implantation technique, and aftercare are refined, TENs may prove to be the ideal implant to stabilize most pediatric femur shaft fractures, avoiding the prolonged immobilization and complications of traction and spica cast

Twenty-seven cases of traumatic intracerebral hematoma were treated from 1977 to 1979. The intracerebral hematomas are classified into three groups: central type, hematoma within contusional area and contusional hematoma, according to the CT findings and the clinical course. Fourteen of these cases are diagnosed as contusional hematoma which show a normal CT scan, subarachnoidal hemorrhage, subdural hematoma and epidural hematoma without any kind of intracerebral high density in the initial CT scan performed within 6 hours after injury. Ten of the cases were found during conservative treatment; in 2 cases, hematomas were revealed within 24 hours; in 2 more cases within 48 hours, and in 6 cases, within 3 - 5 days following injury. In the other 4 cases, hematoma occurred 1 - 2 days following the emergency evacuation of a subdural hematoma and decompressive craniectomy. Based on the clinical experience outlined above, it is our current practice in diagnosing patients with contusional hematoma to perform repeat CT scanning within 5 - 6 days after injury whenever isodensity or subarachnoidal hemorrhage with a shift in the midline structure is observed in an initial CT scan within 6 hours or whenever an evacuation of the subdural hematoma with decompressive craniectomy is performed.

Marked portosystemic venous anastomosis of the parumbilical veins is referred to as the Cruveilhier-Baumgarten syndrome. Opening of these vessels has been described mainly in the sonographic literature. In this case report CT and MR findings are presented, which have been confirmed by angiography. This paper is intended to draw the radiologist's attention to dilatation of the parumbilical veins, which is a highly specific sign of portal hypertension resulting from intrahepatic blockage.

To assess the immediate effect of conventional and burst transcutaneous electrical nerve stimulation (TENS) in combination with cryotherapy on pain threshold and tolerance in healthy individuals. Randomised, controlled trial. University laboratory. One hundred and twelve healthy women. Volunteers were allocated at random to seven groups (n=16): (1) control, (2) placebo TENS, (3) conventional TENS, (4) burst TENS, (5) cryotherapy, (6) cryotherapy in combination with burst TENS, and (7) cryotherapy in combination with conventional TENS. Pain threshold and tolerance were measured by applying a pressure algometer at the lateral epicondyle of the humerus, before and after each intervention. The primary outcome measure was pressure pain threshold. A significant increase in pain threshold and tolerance at the 5% level of significance was recorded as follows: burst TENS {pain threshold: mean difference 1.3 [95% confidence interval (CI) 1.4 to 1.2]; pain tolerance: mean difference 3.8 (95% CI 3.9 to 3.7)}, cryotherapy [pain threshold: mean difference 1.3 (95% CI 1.4 to 1.2); pain tolerance: mean difference 1.9 (95% CI 1.8 to 2.0)] and cryotherapy in combination with burst TENS [pain threshold: mean difference 2.6 (95% CI 2.4 to 2.8); pain tolerance: mean difference 4.9 (95% CI 5.0 to 4.8)]. Cryotherapy in combination with burst TENS provided greater analgesia compared with the other groups (Pcryotherapy in combination with burst TENS to reduce induced pain, and suggest a potentiating effect when these techniques are combined. No such association was found between cryotherapy and conventional TENS. Copyright © 2014 Chartered Society of Physiotherapy. Published by Elsevier Ltd. All rights reserved.

Chronic low-back pain (LBP) affects a significant proportion of the population. Transcutaneous electrical nerve stimulation (TENS) was introduced more than 30 years ago as an adjunct to the pharmacological management of pain. However, despite its widespread use, the usefulness of TENS in chronic LBP is still controversial. The aim of this systematic review was to determine the effectiveness of TENS in the management of chronic LBP. We searched the Cochrane Central Register of Controlled Trials (Issue 2, 2005), MEDLINE, EMBASE and PEDro up to April 1, 2005. Only randomized controlled clinical trials (RCTs) evaluating the effect of TENS on chronic LBP were included. Abstracts were excluded unless further data could be obtained from the authors. Two reviewers independently selected trials and extracted data using predetermined forms. Heterogeneity was tested with Cochrane's Q test. A fixed effect model was used throughout for calculating continuous variables, except where heterogeneity existed, in which case, a random effects model was used. Results are presented as weighted mean differences (WMD) with 95% confidence intervals (95% CI), where the difference between the treated and control groups was weighted by the inverse of the variance. Standardized mean differences (SMD) were calculated by dividing the difference between the treated and control by the baseline variance. SMD were used when different scales were used to measure the same concept. Dichotomous outcomes were analyzed with odds ratios. The only two RCTs (175 patients) meeting eligibility criteria differed in study design, methodological quality, inclusion and exclusion criteria, type and method of TENS application, treatment schedule, co-interventions and final outcomes. In one RCT, TENS produced significantly greater pain relief than the placebo control. However, in the other RCT, no statistically significant differences between treatment and control groups were shown for multiple outcome measures. Pre

TENS (transcutaneous electrical nerve stimulation) for labour pain.

Science.gov (United States)

Francis, Richard

2012-05-01

Because TENS is applied inconsistently and not always in line with optimal TENS application theory, this may explain why TENS for labour pain appears to be effective in some individuals and not in others. This article reviews TENS theory, advises upon optimal TENS application for labour pain and discusses some of the limitations of TENS research on labour pain. TENS application for labour pain may include TENS applied to either side of the lower spine, set to 200 mus pulse duration and 100 pulses per second. As pain increases, TENS intensity should be increased and as pain decreases, TENS intensity should be reduced to maintain a strong but pain free intensity of stimulation. This application may particularly reduce back pain during labour.

Full Text Available Objectives The work serves as a preliminary evaluation of the utility of the full-body radiography in examining cases of SUDI. Setting This paper reviews findings from full-body digital radiography in cases of sudden unexpected death in infants (SUDI in 2008 at the Salt River Forensic Pathology Laboratory in Cape Town. Subjects Cases of SUDI referred to the mortuary and undergoing full-body digital radiography were reviewed (192 cases. Design Imaging reports were cross-referenced with death registry data. Manner of death, cause of death, whether an autopsy had taken place, and radiological findings, were recorded and analysed. Results The absence of bony fractures was recorded as an imaging finding in 40% of cases. The most common type of imaging pathology was lung disease. In cases where autopsies were performed and pathology was found on imaging, the findings of the two methods of examination were consistent. Conclusions Imaging may have served to assist CoD determination based on case history, and therefore full-body radiography may improve the workflow in busy forensic pathology laboratories. More detailed and consistent recording of imaging findings is required before stronger conclusions may be drawn regarding the utility of full body digital imaging of paediatric cases in forensic pathology laboratories.

The significance of sonographic findings 1 week or less after appendectomy is difficult to evaluate without knowing the inconsequential abnormalities that may occur in these patients. Accordingly, we performed postoperative sonography on patients who had a normal course after appendectomy to determine the findings that can be considered normal within 1 week after surgery. Forty-four patients who had an appendectomy for acute appendicitis and who had normal findings at clinical follow-up 5 days and 6 months later were included in the study. In all patients, sonograms were obtained on the fifth postoperative day and interpreted by a radiologist who did not know the surgical findings. Ten fluid collections (23%) were found in the pericecal area, ranging in size from 10 x 10 mm to 40 x 20 mm. The collections were hypoechoic or anechoic, crescent-shaped, and immobile. Fluid collections were more common in cases of suppurative appendixes (6/20, 30%) than in cases of inflamed appendixes (4/19, 21%) and in retrocecal appendixes (3/9, 33%) than in normally located appendixes (7/34, 21%). However, the differences were not statistically significant (p > .05). Inconsequential fluid collections are detected with considerable frequency on postoperative sonograms 5 days after an appendectomy. Consequently, not every fluid collection should be considered an abscess.

Objective: The arterial spasm which often seen in the coronary angiography was considered as a result of the pathological spasm of the coronary artery or a complication of catheterization. The coronary arterial spasm is a considerable situation because it increases the danger of stenotic lesions in coronary artery, which should be managed immediately. Methods: In total 37 patients presented with coronary arterial spasm in the coronary angiography (Judkins method): 23 male and 14 female, aged 43-60 years (the 47 years in average). Spasms were relieved in all patients after the administration of glonoin. Results: Solitary spasm were the most common, the angiographic findings were long section (>10 mm) with stenosis of 50%-65% in left anterior descending artery (12 cases), or in the middle and near portion of the right coronary artery (5 cases), where the orifice of the branches were involved; severe stenosis of the orifice of the right coronary artery (3 cases); irregular, mild and local spasm in left anterior descending artery or circumflex (8 cases). And multiple spasm was observed in left anterior descending artery (4 cases) or in the right coronary artery (5 cases). In 19 cases, stenosis accompanying with spasm were revealed and local spasm were observed at the site of arterial sclerosis. Conclusion: The spasm owing to the catheterization doesn't result in chest discomfort and changes in EKG, while pathological spasm occurs in the population with high risk of coronary heart disease, which indicates the potential myocardial infraction. The angiographic findings helps differentiating the two situation

Powers of ten

CERN Document Server

1979-01-01

Powers of Ten is a 1977 short documentary film written and directed by Charles Eames and his wife, Ray. The film depicts the relative scale of the Universe in factors of ten (see also logarithmic scale and order of magnitude). The idea for the film appears to have come from the 1957 book Cosmic View by Kees Boeke. The film begins with an aerial image of a man reclining on a blanket; the view is that of one meter across. The viewpoint, accompanied by expository voiceover, then slowly zooms out to a view ten meters across ( or 101 m in standard form), revealing that the man is picnicking in a park with a female companion. The zoom-out continues, to a view of 100 meters (102 m), then 1 kilometer (103 m), and so on, increasing the perspective—the picnic is revealed to be taking place near Soldier Field on Chicago's waterfront—and continuing to zoom out to a field of view of 1024 meters, or the size of the observable universe. The camera then zooms back in to the picnic, and then to views of negative pow...

Ectodermal dysplasia are group of inherited disorders involving the developmental defects of ectodermal structures like hair, teeth, nails, sweat glands, and others. X-linked recessive inheritance is most common. Here we describe perinatal autopsy findings in a case of de novo ectodermal dysplasia in a female fetus. To the best of our knowledge, this is the first fetal autopsy description in a case of ectodermal dysplasia.

Population-level impact of active tuberculosis case finding in an Asian megacity.

David W Dowdy

Full Text Available BACKGROUND: The potential population-level impact of private-sector initiatives for tuberculosis (TB case finding in Southeast Asia remains uncertain. In 2011, the Indus Hospital TB Control Program in Karachi, Pakistan, undertook an aggressive case-finding campaign that doubled notification rates, providing an opportunity to investigate potential population-level effects. METHODS: We constructed an age-structured compartmental model of TB in the intervention area. We fit the model using field and literature data, assuming that TB incidence equaled the estimated nationwide incidence in Pakistan (primary analysis, or 1.5 times greater (high-incidence scenario. We modeled the intervention as an increase in the rate of formal-sector TB diagnosis and evaluated the potential impact of sustaining this rate for five years. RESULTS: In the primary analysis, the five-year intervention averted 24% (95% uncertainty range, UR: 18-30% of five-year cumulative TB cases and 52% (95% UR: 45-57% of cumulative TB deaths. Corresponding reductions in the high-incidence scenario were 12% (95% UR: 8-17% and 27% (95% UR: 21-34%, although the absolute number of lives saved was higher. At the end of five years, TB notification rates in the primary analysis were below their 2010 baseline, incidence had dropped by 45%, and annual mortality had fallen by 72%. About half of the cumulative impact on incidence and mortality could be achieved with a one-year intervention. CONCLUSIONS: Sustained, multifaceted, and innovative approaches to TB case-finding in Asian megacities can have substantial community-wide epidemiological impact.

The authors report 2 cases of gangliogliomas of the sellar region, one of which was associated with chromophobe adenoma. Case 1. A 14-year-old female was admitted for a visual disturbance. Neurological examination showed bitemporal hemianopsia and secondary optic atrophy. CT scan showed an isodense mass in the suprasellar region, with homogneous enhancement by contrast medium and an accompanying low-density area in the left thalamus adjacent to the enhanced tumor mass. The histological diagnosis of the surgical specimen was ganglioglioma. Case 2. A 52-year-old female was admitted under the diagnosis of pituitary adenoma. Neurological examination showed bitemporal hemianopsia and signs of acromegaly. Plain skull X-ray film showed sellar ballooning and decalcification of the posterior clinoid process. The tumor resected in the first operation was histologically diagnosed as chromophobe adenoma mixed with ganglioglioma. In the follow-up, she showed signs and symptoms of a recurrent tumor, which was revealed to be ganglioglioma without any recurrence of chromophobe adenoma in the subsequent operations. The CT scan before the second operation showed an isodense supraand intrasellar mass with marked enhancement. Ganglioglioma is a rare, benign, nerve-cell tumor, mostly occurring in childhood and adolescence. The CT findings, together with the clinical history, the age of the patient, and the tumor location, may suggest the tentative preoperative diagnosis of ganglioglioma.

Interdisciplinary team work is increasingly prevalent, supported by policies and practices that bring care closer to the patient and challenge traditional professional boundaries. To date, there has been a great deal of emphasis on the processes of team work, and in some cases, outcomes. This study draws on two sources of knowledge to identify the attributes of a good interdisciplinary team; a published systematic review of the literature on interdisciplinary team work, and the perceptions of over 253 staff from 11 community rehabilitation and intermediate care teams in the UK. These data sources were merged using qualitative content analysis to arrive at a framework that identifies characteristics and proposes ten competencies that support effective interdisciplinary team work. Ten characteristics underpinning effective interdisciplinary team work were identified: positive leadership and management attributes; communication strategies and structures; personal rewards, training and development; appropriate resources and procedures; appropriate skill mix; supportive team climate; individual characteristics that support interdisciplinary team work; clarity of vision; quality and outcomes of care; and respecting and understanding roles. We propose competency statements that an effective interdisciplinary team functioning at a high level should demonstrate.

High re-tear rate is reported after rotator cuff repair in large and massive tear cases. Previously, we reported that 15% of patients after rotator cuff repair showed re-tear in MRI findings. In this study, 116 consecutive rotator cuff repaired patients who had been operated arthroscopically since 2003 were evaluated for size, torn site, fixation methods, mobility, and tendon quality. In addition, rehabilitation methods and occupation after revision were also evaluated. There were four patients who underwent re-operation. Rotator cuff repairs by revision surgery failed mechanically due to two reasons: the main factor of failure was suture material breakage in three cases and the second was tendon pulling through sutures in one case. The lack of thread strength was suggested. In addition, it is important to pull cuff stump to greater tubercle without excessive tension. Of re-operated cases, three engaging in manual labor suffered large and massive tear. In two cases, premature return to manual labor suggested cause of re-tear. (author)

2004-01-01

Hallervorden-Spatz syndrome is a neuro degenerative disease, autosomic recessive with two clinical features: early and late onset. Psychiatric, pyramidal and extrapyramidal signs are present in the late subtype. We report the case of a 41-old woman with extrapyramidal signs. Magnetic resonance imaging (MRI) showed the eye-of-the-tiger sign in the medial globus pallidus. This is due to a gliosis (increased signal) and accumulation of surrounding iron (decreased signal intensity) in long T R sequences. There is a strong relationship between MRI findings and the gene mutation responsible for this disease. It makes the MRI sensible for diagnosing this syndrome. (author)

Brucellosis is a systemic infectious disease, and musculoskeletal involvement is a frequent complication. Particularly, spondylitis is a common involvement. However, early diagnosis of brucellar spondylitis is often difficult due to non-specific clinical symptoms and long latent period. Especially in Korea, where tuberculosis is an endemic disease, differentiation between tuberculous and brucellar spondylitis is clinically and radiologically more challenging. A 59-year-old male cattle farmer, who presented with non-specific back pain, had spondylitis on magnetic resonance imaging (MRI), and serologic test finally confirmed brucellar spondylitis. Therefore, we report a case of a rather rare disease in Korea, brucellar spondylitis with a review of MRI findings.

An 80-year-old man with insulin-dependent diabetes mellitus presented to the hospital with low back pain. He was initially managed with non-steroidal anti-inflammatory drugs, tramadol and epidural steroid injection. Transcutaneous electrical nerve stimulation (TENS), applied on the back and buttocks, was subsequently advised. Initially, TENS was applied once every 24 hours. On improvement of pain symptoms, it was increased to thrice every 24 hours. The patient then complained of symptoms of hypoglycaemia (blood sugar level TENS resulted in raised blood sugar level. When TENS was restarted, the same hypoglycaemic response was noted. The insulin dosage was adjusted to half of the patient's routine daily requirement with continued application of TENS. This incidental finding has alerted us to hypoglycaemic episodes following TENS application, which may be due to effective pain control, decreased sympathetic stimulation, enhanced insulin sensitivity or altered muscle metabolism due to electrical stimulation.

2013-01-01

False aneurysm degeneration is a known complication of patch aortoplasty for coarctation of the aortic isthmus. Open surgical treatment consists of prosthetic graft repair of the involved aorta, often requires circulatory arrest to achieve a safe proximal aortic control and perform proximal anastomosis, and finally is associated with substantial perioperative morbidity. Endografting of the diseased aorta is a valuable alternative to open repair, when feasible, with good short and long term results. We now report one more case of false aneurysm ten years after Dacron patch aortoplasty for isthmic coarctation in a 26-year-old woman, successfully treated by endovascular repair via the left common iliac artery, and a complete exclusion of the aneurysm at two year follow-up.

Computed tomographic (CT) findings of pancreatic ductal adenocarcinoma were studied with the combined method of early enhancement CT and high dose enhancement CT in 72 carcinomas. Common Findings were change in pancreatic contour, abnormal attenuation in a tumor and dilatation of the main pancreatic duct. The incidence of abnormal attenuation and dilatation of the main pancreatic duct and bile duct was constant regardless of tumor size. The finding of hypoattenuation at early enhancement CT was most useful for demonstrating a carcinoma. However, this finding was negative in ten cases, five of which showed inhomogenous hyperattenuation at high dose enhancement CT. The detection of change in pancreatic contour and dilatation of the main pancreatic duct was most frequent at high dose enhancement CT. The finding of change in pancreatic contour and/or abnormal attenuation in a tumor could be detected in 47 cases at plain CT, 66 at early enhancement CT and 65 at high dose enhancement CT. Since the four cases in which neither finding was detected by any CT method showed dilatated main pancreatic duct, there was no case without abnormal CT findings. This combined CT method will be a reliable diagnostic technique in the imaging of pancreatic carcinoma. (author)

The Ten-Minute Neighbourhood Is [not] a Basic Planning Unit for Happiness in Egypt

Abeer Mohamed Elshater

2016-04-01

Full Text Available This paper investigates the relationship between inhabitants’ happiness and the right to the city in the status quo of Egyptian neighborhoods. Although services are easily accessible, by ten-minute walks in a suitable ambience, happiness is not achieved. The research aims to, first, review the literature that provides a guideline for ten-minute neighborhoods. Second, this study conducts a comparative content analysis of recent online articles on the right to the city. Third, the study tests findings from Egyptian neighborhood settings. The idea of a ten-minute neighborhood is manageable. The hypothesis concerns a compliant design. It is a logical assumption that people who live within ten minutes walking distance of essential facilities in their area can minimize several problems and maximize a healthy lifestyle. The supposed issue causes the right to the city to affect the relationship between ten-minute neighborhoods and citizens’ happiness. This assumption can be established through site observation and oriented questionnaires. This paper contributes by presenting new planning units that suit the current context of the old cities in the Middle East and North Africa region, based on walking distances of ten minutes or less with reference to the right to the city. This planning unit can result in citizens’ happiness.

Objective: To discuss the radiographic findings and diagnosis in lupus enteritis. Methods: 4 cases of lupus enteritis (male 1, female 3) were studied. Abdominal pain was the chief complaint in all these cases. Before and after steroid therapy, small bowel contrast study was performed. Results: In one patient abdominal plain film revealed slight dilatation of jejunum with air-fluid levels. Small bowel contrast study showed effacement and (or) nodules of the mucosal folds, thumb printing, spasm and some degree of rigidity and narrowing of the lumen. Clinical symptoms and radiographic findings became normal after steroid therapy. Conclusions: If a patient with systemic lupus erythematosus presents abdominal symptoms, small bowel contrast study should be done. It is important and helpful to assist the diagnosis, to decide therapeutic plan and to follow up the effect of treatment

Purpose: To assess the diagnostic value of two-dimensional coronary magnetic resonance (MR) angiography in patients evaluated for ischemic heart disease. Materials and methods: Ten patients who underwent selective cardiac catheterization with coronary MR angiography were evaluated with two-dimensional coronary MR angiography. Coronary MR angiography was performed with breath-hold fat-suppressed ECG-gated Turbo-FLASH with K-space segmentation using a 1.5 T imager. Results: The left main coronary artery, proximal left anterior descending artery, circumflex artery and right coronary artery were demonstrated in all cases. Continuous segments (mean) of left anterior descending, circumflex and right coronary arteries visualized on MRA were 6.72 +- 3.16 cm, 3.67 +- 4.81 cm and 7.93 +- 3.12 cm respectively. The overall sensitivity for detection of hemodynamically significant coronary artery lesion (≥50%) was 62.5% respectively. Conclusion: Breath-hold two-dimensional coronary MR angiography was useful in showing relatively long segments of the main coronary arteries and also has potential in depicting hemodynamically significant coronary artery lesions

2015-12-01

Chronic low back pain (CLBP) is a highly prevalent and disabling musculoskeletal pain condition among older adults. Transcutaneous electrical nerve stimulation (TENS) is commonly used to treat CLBP, however response to TENS in older adults compared with younger adults is untested. In a dose-response study stratified by age, 60 participants with axial CLBP (20 young, 20 middle-aged, 20 older) received four 20-minute sessions of high-frequency high-intensity TENS over a 2- to 3-week period in a laboratory-controlled setting. Experimental measures of pain sensitivity (mechanical pressure pain detection threshold) and central pain excitability (phasic heat temporal summation and heat aftersensations) were assessed before and after TENS. Episodic or immediate axial CLBP relief was assessed after TENS via measures of resting pain, movement-evoked-pain, and self-reported disability. Cumulative or prolonged axial CLBP relief was assessed by comparing daily pain reports across sessions. Independent of age, individuals experienced episodic increase in the pressure pain detection threshold and reduction in aftersensation after TENS application. Similarly, all groups, on average, experienced episodic axial CLBP relief via improved resting pain, movement-evoked pain, and disability report. Under this design, no cumulative effect was observed as daily pain did not improve for any age group across the 4 sessions. However, older adults received higher TENS amplitude across all sessions to achieve TENS responses similar to those in younger adults. These findings suggest that older adults experience similar episodic axial CLBP relief to that of younger individuals after high-frequency, high-intensity TENS when higher dose parameters are used. This study examined age group differences in experimental and axial CLBP response to TENS, delivered under the current recommended parameters of strong, but tolerable amplitude. Older adults had comparable TENS response although at higher TENS

Denise Vasconcelos Fernandes

Full Text Available Introduction Cephalgia or cephalalgia is one of the most common symptoms in the general population. Objective To compare the efficacy of physical therapy modalities, through manual therapy and the effect of Transcutaneous Nerve Stimulation (TENS for tension-type cephalalgia. Materials and methods The study was compounded by 60 subjects, but only 40 of them completed it, due to the exclusion criteria. These were divided into control group and intervention group. The control group received treatment — manual therapy. The intervention group received TENS Burst. Patients underwent ten sessions of treatment, made at every two days on a week, lasting 30 minutes each session. Results The characteristics related to lifestyle, postural issues and range of motion are responsible for the main causes of tension-type cephalalgia. Discussion treatments showed effective results in all cases in relation to pain intensity, but the use of manual therapy techniques give the patient a better quality of life compared to the use of TENS. Final considerations The treatment of this condition deserves analysis and studies; however, there are only a few studying physical therapy techniques, especially regarding to the use of TENS.

Full Text Available Recently, the veterinarians are dealing with a number of cases that require forensic expertise. Such a circumstance could be the accidental electrocution in animals, one of the causes of unnatural death. There is a scarcity with reference to the pathological findings in veterinary forensic medicine. In this paper, we present the main lesions that occurred in a horse with accidental electrocution that was presented for complete necropsy survey. A horse corpse was sent to the Pathology Department (Faculty of Veterinary Medicine, Cluj-Napoca, Romania for a full medical survey. Preliminary results and external examination: the body was in rigor mortis; from the nasal cavities drained out reddish foam and in the mouth was observed the presence of ingested feed (straw that was not chewed, suggesting a quick death. The findings detected after internal examination of the carcass were poor blood coagulability, haemorrhagic diathesis throughout the body, with haemorrhages of various sizes in different body regions (e.g., muscles of the withers, in the gluteal muscle, the mucosa of epiglottis, larynx, trachea, in the interstitium of the lung, and ecchymosis in the left kidney. Some other lesions detected were infarcts and haemorrhages in the fundic region of the stomach’s mucosa. In electrocution, haemorrhages are most often located in the respiratory tract, aspect observed in our case too. However, the diagnosis of electrocution has to corroborate the necropsy findings (which are not specific, with some other data such as the fulminant death and inspection of power source.

To evaluate the radiological findings and clinical course of the complications arising after nonbiliay laparoscopic gastrointestinal surgery (NLGS). We retrospectively reviewed the clinical records of 131 patients who underwent NLGS (83 cases involving colorectal surgery, 18 splenectomies, 14 appendectomies, ten adrenalectomies, three lumbar sympathectomies, two Duhamel's operation, and one peptic ulcer perforation repair) over a four-year period. Among these 131 patients, the findings of fifteen in whom postoperative complications were confirmed were analysed. The radiologic examinations these patients underwent included CT (n=3D8), barium enema and fistulography (n=3D4), ultrasonography (n=3D3), ascending venography of the lower legs (n=3D2), and penile Doppler sonography (n=3D1). We evaluated the radiologic findings and clinical courses of early (within 2 weeks) and late (after 2 weeks) postoperative complications. Sixteen cases of postoperative complications developed in fifteen patients ; in 14 (17%) after colorectal surgery and in one (6%) after splenectomy. Eleven of the sixteen cases (69%) involved early complications, consisting of an abscess in three, ischemic colitis in two, hemoperitoneum in one, perforation of the colon in one, pancreatitis in one, recto-vaginal fistula in one, deep vein thrombosis after colorectal surgery in one, and abscess after splenectomy in one. The remaining five cases (31%) involved late complications which developed after colorectal surgery, comprising anastomosic site stricture in two, abdominal wall (trocar site) metastasis in one, colo-cutaneous fistula in one, and impotence in one. Among the 16 cases involving postoperative complications, recto-vaginal fistula, colon perforation, and abdominal wall metastasis were treated by surgery, while the other thirteen cases were treated conservatively. Various postoperative complications develop after NLGS, with a higher rate of these being noted in cases involving colorectal

2008-01-01

Wirsungocele is defined as a cystic dilatation of the terminal portion of the main pancreatic duct, and this is an extremely rare malady. The pathophysiology of Wirsungocele has been proposed that a congenital or acquired weakness in the distal duct that's associated with functional obstruction may lead to the formation of Wirsungocele. In addition, mechanical obstruction of the distal duct has been considered as another mechanism of Wirsungocele. We report here on the imaging findings of two cases of Wirsungocele that seemed to occur by different pathophysiologic mechanisms

Applying the Case Management CourTools: Finding from an Urban Trial Court

2012-06-01

Full Text Available The National Center for State Courts (NCSC recently promulgated 10 trial court performance measures, referred to as CourTools. Measures 2, 3, 4, and 5 provide a methodology by which court managers can examine their management and processing of cases. The measures include clearance rate (measure 2, time to disposition (measure 3, age of active pending caseload (measure 4, and trial date certainty (measure 5. The objective of this research was threefold. The first aim was to assess the viability of using the case management measures to examine case processing trends in a New Jersey (NJ urban trial court. Each measure was reviewed to determine the tool’s applicability to the criminal division of the court. The second objective (pursued as a parallel to the first was to present the findings in the same context as the CourTools’ framework to determine its practicality. The final goal was to serve as a platform for other courts on the national and international level that do not yet use performance measures. These courts, diverse as they are, may use the methodologies and findings of this case study as a reference and guide to develop their own program to measure the court’s productivity and efficiency. To that end, this case study sought to answer the following questions in determining the applicability of the CourTools to the selected court and by extension, its potential for more universal application to other court systems. First, what is the relevance of measurements to the courts and why is it important, if at all? Second, what are the CourTools? Third, can the measurement model be applied to an actual court and if so, how is it executed and illustrated in practice? Finally, what are the implications of the findings for the court in question, as well as, other courts that seek to incorporate the CourTools to measure performance?

2006-01-01

We wanted to evaluate the barium enema findings of milk allergy in infants. Retrospective evaluation of the plain abdominal radiography and barium enema findings was performed in fifteen young infants suffering with milk allergy. The presence of gaseous distension, rectal gas, paralytic ileus and mechanical obstruction was evaluated on the plain radiography. The presence of spasm, a transitional zone, a reversed rectosigmoid index and mucosal irregularity was analyzed on the barium enema; the presence of barium retention was also evaluated on 24-hour-delayed plain radiography. Paralytic ileus was the most common finding on the plain radiography (93%). On the barium enema, continuous spasm of the colon, ranging from the rectum to the descending colon, was revealed in ten infants (67%). A transitional zone was observed in one infant and a reversed rectosigmoid index was revealed in four. Mucosal irregularity was observed in two infants. Barium retention was demonstrated in 11 of fifteen cases: throughout the entire colon (n = 3), from the rectum to the descending colon (n = 7), and up to the transverse colon (n = 1). The most common barium enema finding of milk allergy in infants was spasm of the distal colon. The other findings were a transitional zone, a reversed rectosigmoid index, mucosal irregularity and barium retention

Computed tomography (CT) is the first noninvasive method available for directly visualizing brain edema in man. On CT scans perifocal edema is shown as an area of low density surrounding a lesion. The purpose of this report is to evaluate the effect of corticosteroids on brain edema as seen by CT (HITACHI CT-H 250). Nine patients with brain-tumor and one with brain-abscess were treated with betamethasone for about ten days (dosage started with 12 - 16 mg/day, and tapered). In eight cases, and improvement in the neurological findings was observed. An impressive reduction of peritumoral edema was shown on CT scans in six of these eight cases. There was, however, no significant correlation between the degree of the reduction of edema on CT and that of the improvement in neurological findings. The mode of the CT number in the region of edema did not differ significantly between pre- and post-steroid treatment in the cases showing a recognizable reduction of edema on CT. This failure to change is probably due to the insufficient mechanical accuracy of the CT scanner at the present stage of technology. Through our experiences, it seems that CT is one of the most promising tools for a dynamic study of brain edema in man. (author)

Full Text Available Parag Suresh Mahajan, Nazeer Ahamad, Sheik Akbar Hussain Department of Radiology, Al-Khor Hospital, Hamad Medical Corporation, Doha, Qatar Abstract: An autoamputated wandering calcified ovary (AWCO is an extremely rare cause of abdominal calcification in the pediatric population. We present the magnetic resonance imaging (MRI features of AWCO in a child. To our knowledge, the MRI features of AWCO have not been previously described in the published literature. Our case report indicates that the MRI findings are characteristic in the diagnosis of an AWCO and can completely obviate the need for invasive procedures in this mostly benign disease. An AWCO should be considered in all cases of mobile calcific opacities on radiographs in female patients. We advise that MRI be conducted in all suspected cases of AWCO for accurate and noninvasive diagnosis, and regular follow-up should be performed with ultrasound. The findings in our case report have the potential to change the course of investigations and management in suspected cases.

A case of suspected ''Bickerstaff's encephalitis'' was presented with special reference to the CT findings. A 4-year-old girl exhibited fever and nausea after the beginning of December, 1983, followed by unsteady gait on January 1, 1984. She was admitted to another hospital and diagnosed by means of a spinalfluid examination as having aseptic meningitis. Her symptoms subsided transiently, but then she began again to suffer recurrently from unsteady gait on January 27. After that she developed dysarthria and dysphagia, a disturbance of eye movement was observed, and she became lethargic and disoriented. On February 6, she was transferred to our hospital. Plain CT scan on admission revealed a low-density area on the left cerebellar peduncle and the inferior medial part of the left temporal lobe. Moreover, the low-density area was heterogenously enhanced with the contrast medium. Angiography showed no abnormal findings. Considering these CT findings, we suspected a pontine tumor. Four days after her admission, however, her symptoms and signs began rapidly to subside, and also the abnormal findings on the CT scan diminished gradually as the symptoms were relieved. On March 2, she was discharged without any neurological abnormality. (author)

INTEGRATING CASE-BASED REASONING, KNOWLEDGE-BASED APPROACH AND TSP ALGORITHM FOR MINIMUM TOUR FINDING

Directory of Open Access Journals (Sweden)

Full Text Available Imagine you have traveled to an unfamiliar city. Before you start your daily tour around the city, you need to know a good route. In Network Theory (NT, this is the traveling salesman problem (TSP. A dynamic programming algorithm is often used for solving this problem. However, when the road network of the city is very complicated and dense, which is usually the case, it will take too long for the algorithm to find the shortest path. Furthermore, in reality, things are not as simple as those stated in AT. For instance, the cost of travel for the same part of the city at different times may not be the same. In this project, we have integrated TSP algorithm with AI knowledge-based approach and case-based reasoning in solving the problem. With this integration, knowledge about the geographical information and past cases are used to help TSP algorithm in finding a solution. This approach dramatically reduces the computation time required for minimum tour finding.

The Ultrasound and MRI Findings of Uterine Adenofibroma: A Case Report

International Nuclear Information System (INIS)

Kim, Hyun Jung; Rha, Sung Eun; Byun, Jae Young; Lee, Ah Won

2011-01-01

Adenofibroma is an extremely rare benign m'ullerian mixed tumor composed of epithelium and mesenchymal cells. Most uterine adenofibromas occur in the endometrium, but they rarely protrude into the vagina. To date, only a few such cases with the imaging findings have been reported. Therefore, we report here on the sonographic and magnetic resonance (MR) imaging findings of a case of endometrial adenofibroma protruding into the vaginal cavity in a 28-year-old woman. The uterine adenofibroma appeared as a large intracavitary echogenic mass containing multiple small internal cysts, and it was distending the vaginal cavity on transrectal sonography. T2- weighted MR images showed a large intracavitary mass with heterogeneous high signal intensity protruding into the vaginal cavity. On gadolinium-enhanced T1-weighted MR images, heterogeneous septa-like enhancement was noted in the mass. Although uterine adenofibroma is extremely rare, adenofibroma can be suggested as a possible diagnosis when an intracavitary uterine mass, with multiple internal small cystic components and enhancing septa-like structures, is protruding into the vaginal cavity on imaging

The CT findings in a case of neonatal accute subdural hematoma are presented. CT demonstrated a crescentic high density area in the subdural space over the left cerebral hemisphere and an oval high density area in the left occipital region. The latter was suspected of being an intracerebral hematoma. Emergency craniotomy revealed that the high density area was due to a subdural hematoma between the occipital lobe and the tentorium cerebelli. (orig.)

Purpose: To retrospectively review magnetic resonance (MR) imaging features in a series of six infantile fibrosarcomas to find out if MR can suggest this unusual diagnosis and to highlight the value of MR during and following treatment. Materials and methods: The records of six cases of histologically proven infantile fibrosarcoma were retrieved from the files of our cancer center. All imaging data available were consensually reviewed by two radiologists. Results: There were five females and one male (age range at diagnosis, 0-12 months; mean, 6 months). The most common finding was a well-circumscribed single mass in five patients (83%). All tumors had arisen on limbs; at their proximal or distal extremity or at the root of the limb. The masses were 9 cm large in mean diameter. The initial tumor signal was isointense to muscle on T1-weighted and hyperintense on T2-weighted sequences. All masses were well circumscribed and half of them contained internal fibrous septa. The internal signal was homogeneous in three patients and heterogeneous in the three others. An intense enhancement was seen in all three contrast-enhanced exams available; heterogeneous in two cases and homogeneous in one. Osseous erosion was observed in only one patient who was the only one with distant metastasis. After treatment (chemotherapy and very limited surgery), tumors had totally disappeared, leaving muscle fat infiltration in two patients and subcutaneous fat hypertrophy in one patient. Conclusion: Although imaging findings are not specific of infantile fibrosarcoma, this diagnosis could be suggested when MR imaging depicts a large well-circumscribed mass arising in a limb at birth or during the neonatal period. This mass is sometimes heterogeneous and septate and exhibits an isointense T1- and hyperintense T2-weighted signals and strong enhancement. MR is also the technique of choice for follow-up during treatment which consists nowadays almost exclusively in chemotherapy.

1997-01-01

Purpose: To evaluate MR imaging of the hip in patients with a clinically suspected impacted fracture of the femoral neck in cases where conventional plain films show negative or equivocal findings. Material and Methods: Twenty-seven such patients were prospectively examined by MR imaging with a 1.0 T unit, within 24 hours of admittance to hospital. A coronal T1-weighted turbo spin-echo sequence (n=27), and a coronal STIR sequence (n=25) or a coronal T2-weighted turbo spin-echo fast saturation sequence (n=2) were used. The evaluations were made by 2 radiologists with experience in musculoskeletal radiology. Results: There were 6 patients with a petrochanteric fracture, 2 without and 4 with slight displacement. Five patients had an impacted fracture of the femoral neck, and 3 had a fracture of the superior pubic bone. Of 2 patients with advanced arthrosis, i had an impacted femoral neck fracture and the other a nondisplaced intertrochanteric fracture. There was 1 patient who had sustained a nondisplaced acetabular fracture with increased joint fluid and muscle contusions. Three patients had muscle contusions only. Two patients had bone marrow contusions only, while 2 others with advanced coxarthrosis had increased joint fluid only. Three patients showed normal findings. Our findings led to emergency surgery in 13 cases, and conservative measures directed to the specific MR findings in 14 patients. Conclusion: MR imaging should be the first modality of choice in examining patients with a clinically suspected impacted fracture of the femoral neck where conventional films show negative or equivocal findings.

In Korean culture, the names of family members are recorded in special family books. This makes it possible to follow the distribution of Korean family names far back in history. It is shown here that these name distributions are well described by a simple null model, the random group formation (RGF) model. This model makes it possible to predict how the name distributions change and these predictions are shown to be borne out. In particular, the RGF model predicts that for married women entering a collection of family books in a certain year, the occurrence of the most common family name 'Kim' should be directly proportional to the total number of married women with the same proportionality constant for all the years. This prediction is also borne out to a high degree. We speculate that it reflects some inherent social stability in the Korean culture. In addition, we obtain an estimate of the total population of the Korean culture down to the year 500 AD, based on the RGF model, and find about ten thousand Kims.

Computed tomography (CT) of ten patients with medulloblastomas was evaluated. Six of them showed solid, nearly homogeneous lesions and a definite enhancement after the infusion of the contrast medium. However, 4 cases showed heterogenous mass lesions composed of areas of a low density and an iso- or slightly high density which was attenuated by contrast enhancement. Histological examinations revealed differentiated medulloblastomas in two of them, but the other two cases were typical medulloblastomas. It should be remembered that medulloblastomas can reveal heterogenous cerebellar midline mass lesions in CT scans. (author)

Florid cemento-osseous dysplasia (FCOD) is a benign jaw lesion originating from periodontal ligament tissues usually asymptomatic and diagnosed accidentally at routine dental radiographic examination. The purpose of this paper is to report three cases diagnosed as FCOD with their clinical, radiographic and histological findings. Radiologic and clinical symptoms of three cases diagnosed as FCOD are presented. Serum alkaline phosphatase test and biopsy taken from two of the patients are discussed to eliminate the Paget's disease. Three patients diagnosed as FCOD and called for routine follow-up. Because of no sign of infection or osteomyelitis, conservative treatment was applied. Radiographic examination is significant for the diagnosis of florid cemento-osseous dysplasia, especially in the asymptomatic cases. The roles of the dentist are to ensure the follow-up of the diagnosed patients and to take the necessary measures for preventing from the infections.

Elastofibroma dorsi is a rare soft-tissue tumor of the chest wall and most commonly presents as a nontender mass adjacent to the inferior angle of the scapula. Its findings on CT and MRI generally lead to the diagnosis. We report a case of a 55-year-old woman with elastofibroma dorsi presenting with painless back mass. On sonography, it appeared as an ill-defined heterogeneous echogenic mass with internal streaky echostructures in bilateral subscapular regions. Excisional biopsy of the tumor was done and the tumor was confirmed as a bilateral elastofibroma dorsi by histopathologic examination.

Pilar sheath acanthoma is a rare benign follicular hamartoma that presents with a central sinus containing keratinous material and is lined by epithelium. It typically occurs on the face, especially on the upper lip and forehead. In our case, the ultrasound (US) feature of pilar sheath acanthoma revealed a well-defined, oval hypoechoic nodule with hypoechoic capping within the dermis over the medial aspect of the calf. To the best of our knowledge, despite many reports on the clinicopathological aspects of pilar sheath acanthoma, this entity has not been well described in the radiologic literature, and US findings have not been documented.

The objective was to determine the contribution of female genital cutting to genital fistula formation in Niger from the case records of a specialist fistula hospital. A retrospective review was undertaken of the records of 360 patients seen at the Danja Fistula Center, Danja, Niger, between March 2014 and September 2016. Pertinent clinical and socio-demographic data were abstracted from the cases identified. A total of 10 fistulas resulting from gurya cutting was obtained: 9 cases of urethral loss and 1 rectovaginal fistula. In none of the cases was genital cutting performed for obstructed labor or as part of ritual coming-of-age ceremonies, but all cutting procedures were considered "therapeutic" within the local cultural context as treatment for dyspareunia, lack of interest in or unwillingness to engage in sexual intercourse, or female behavior that was deemed to be culturally inappropriate by the male spouse, parents, or in-laws. Clinical cure (fistula closed and the patient continent) was obtained in all 10 cases, although 3 women required more than one operation. Gurya cutting is an uncommon, but preventable, cause of genital fistulas in Niger. The socio-cultural context which gives rise to gurya cutting is explored in some detail.

Full Text Available Abstract Background Zoonotic malaria caused by Plasmodium knowlesi is an important, but newly recognized, human pathogen. For the first time, post-mortem findings from a fatal case of knowlesi malaria are reported here. Case presentation A formerly healthy 40 year-old male became symptomatic 10 days after spending time in the jungle of North Borneo. Four days later, he presented to hospital in a state of collapse and died within two hours. He was hyponatraemic and had elevated blood urea, potassium, lactate dehydrogenase and amino transferase values; he was also thrombocytopenic and eosinophilic. Dengue haemorrhagic shock was suspected and a post-mortem examination performed. Investigations for dengue virus were negative. Blood for malaria parasites indicated hyperparasitaemia and single species P. knowlesi infection was confirmed by nested-PCR. Macroscopic pathology of the brain and endocardium showed multiple petechial haemorrhages, the liver and spleen were enlarged and lungs had features consistent with ARDS. Microscopic pathology showed sequestration of pigmented parasitized red blood cells in the vessels of the cerebrum, cerebellum, heart and kidney without evidence of chronic inflammatory reaction in the brain or any other organ examined. Brain sections were negative for intracellular adhesion molecule-1. The spleen and liver had abundant pigment containing macrophages and parasitized red blood cells. The kidney had evidence of acute tubular necrosis and endothelial cells in heart sections were prominent. Conclusions The overall picture in this case was one of systemic malaria infection that fit the WHO classification for severe malaria. Post-mortem findings in this case were unexpectedly similar to those that define fatal falciparum malaria, including cerebral pathology. There were important differences including the absence of coma despite petechial haemorrhages and parasite sequestration in the brain. These results suggest that further

137 patients suffering from classical or complicated migraine were investigated in the Neurology Department of the University of Vienna between 1971 and 1984. 13 of these patients were found to have pathological alterations and their case histories are presented. Clinically, 11 patients suffered from migraine accompagnee (in 2 cases accompanied by epileptic seizures), 1 patient had ophthalmoplegic migraine and 1 had a subarachnoid haemorrhage imitating migraine. The underlying pathological findings were: 1 tumour, 4 arteriovenous malformations, 4 aneurysms, 1 arterio-venous shunt, 1 pathological vascular network, 1 Moya-Moya syndrome and 1 intracerebral haemorrhage without detectable source of bleeding. 8 of the patients underwent successful surgery and most of them showed subsequent clinical improvement. The family history was positive in only 2 patients. The time interval between the occurence of the first symptoms and the establishment of the final diagnosis was up to 25 years. The neurologist should undertake extensive investigation of the patient, including cerebral angiography, if the following criteria apply: hemicrania consistently on the same side; change in type of headache after a number of years; uniform complicating neurological symptoms; additional occurence of epileptic seizures; manifestation of neurological symptoms after the prodromal phase; persistent neurological signs without remission; negative family history; persisting diffuse or locally accentuated EEG changes; pathological CAT results.

Polycystic renal disease are congenital disorders, most of which are fatal in the postnatal period. A series of ten cases of polycystic renal disease diagnosed prenatally by ultrasonography is presented. Diagnostic criteria of ultrasonography for cystic renal disease are; 1. enlarge kidney (4 cases) 2. echogenic density of kidney (3 cases) 3. 0.4 - 0.9cm sized multiple cysts within the renal cortex (3 cases) 4. decreased amount of amniotic fluid (4 cases) 5. hydronephrosis (4 cases) 6. distended bladder (2 cases) 7. absence of bladder (2 cases) Eight of ten cases were confirmed by autopsy. Seven cases had other associated congenital anomalies, i.e. pulmonary hypoplasia (5), hepatic fibrosis (3), congenital heart disease (3), tracheoesophageal fistula with imperforate anus (1), caudal regression syndrome (1), Meckel-Gruber syndrome (1) and ambiguous genitalia (2). Additional cytogenetic study of the fetus and the careful family history taking followed by prenatal diagnosis of cystic renal disease. Precise prenatal diagnosis may allow patients the option of elective abortion or may prevent unnecessary obstetric intervention

Ten reasons are given why supersymmetry is the leading candidate for physics beyond the Standard Model. Ultimately, the experimental discovery of supersymmetric particles at future colliders will determine whether supersymmetry is relevant for TeV scale physics. The grand hope of supersymmetry enthusiasts is to connect TeV scale supersymmetry with Planck scale physics. The ten most pressing theoretical problems standing in the way of this goal are briefly described.

Objective: To investigate the clinical effect of permanent 125 I seeds interstitial implants for metastatic cervical cancer. Methods: Under the guidance of the B-sonography, 125 I seeds were implanted into the eleven cervical lymph nodes of ten patients who had been given tumor resection. The pain relief and tumor size were observed in regular follow-up after one-month treatment. Results: All the patients were followed up for 6-14 months,and the postoperative recovery was good with no complication. One month after the implantation, the pain symptom was alleviated entirely in two nodes and partly in nine nodes. The tumor size shrank in ten nodes while there was no change in one node after one month. Conclusion: Permanent 125 I seeds interstitial implants for metastatic cervical cancer is a safe, minimally invasive and effective treatment. (authors)

Solitary neurofibroma located in the hilum of the liver is extremely rare, particularly without neurofibromatosis. We herein report a case of hilar biliary neurofibroma without signs of von Recklinghausen's disease. A 36-year-old man was admitted to our department with progressive jaundice. The case was diagnosed as hilar cholangiocarcinoma based on preoperative imaging. The patient consequently received a Roux-en-Y hepaticojejunostomy and was confirmed with neurofibroma pathologically. This is the first reported imaging finding of hilar biliary neurofibroma using contrast-enhanced ultrasound, emphasizing the differential diagnosis of biliary tumors.

Adiposis dolorosa (Dercum's disease) is a condition of benign, painful subcutaneous lipomatous lesions associated with weakness, endocrine and lipid abnormalities, and mental disturbances. There is little information documenting the cross-sectional imaging findings that differentiate it from lipomatous and neoplastic soft tissue masses, or massive localized lymphedema. The purpose of this study was to provide a radiological case series of adiposis dolorosa. A 10-year retrospective review of the picture archiving and communications system was performed. Two musculoskeletal radiologists reviewed images to confirm and document imaging features, location, size, and patient demographics. Medical records were reviewed to characterize patients into three groups: one group met at least three of the four criteria of Dercum's syndrome, the second group met less than three criteria, and the third group had clinical diagnosis of cellulitis of the lower extremity. Seventeen cases (25 masses) of adiposis dolorosa were found, nine cases of which met at least three criteria of Dercum's syndrome. All cases in the first two groups demonstrated skin thickening and lymphedema of subcutaneous fat, which was fluid attenuation on CT and low or intermediate T1-weighted and high STIR/T2-weighted MR signal. Two cases with pathology showed mild fatty infiltration with fibrous septa, and the third case showed massive localized lymphedema. The third group of ten cellulitis patients demonstrated non-mass-like subcutaneous edema with similar CT attenuation and MR signal characteristics to the first two groups, but differed by the presence of post-contrast enhancement and non-mass-like appearance in 90 %. Imaging findings of adiposis dolorosa and massive localized lymphedema overlap, as do the symptoms and pathological features. Due to the mass-like engorgement of the soft tissues and pain, patients will often undergo imaging to exclude neoplasm or infection. Knowledge of these

Computed tomographic findings and histological findings of an organized chronic subdural hematoma. A case report

1987-08-01

As chronic subdural hematoma can be readily diagnosed by computed tomography (CT) and can be treated, there are no reports in the literature describing the CT findings of an organized chronic subdural hematoma with a long clinical course. The present case was a 53-year-old male who experienced a series of remissions and aggravations of such symptoms as right hemiparesis and consciousness disturbance for about five years. CT showed a crescent lesion in the left frontoparietal region. In the margin, an uneven, high-density area could be observed running in ward, and in the interior, an iso approx. low-density area could be seen, but no evident enhancement could be noted in either area. The patient died of liver cirrhosis, and an autopsy was performed. The hematoma was encapsulated with a very thick and hard membrane, and directly under the capsule the foci of fresh hemorrhage could be seen along the capsule. The interior of the hematoma was almost entirely organized. The clinical features of this case were considered to reflect the remissions and aggravations of symptoms due to repeated hemorrhages of the chronic subdural hematoma over an extended period.

Five painful (group A) and five symptomless (group B) hips in nine patients with late sequelae of Perthes' disease were studied with plain radiography and magnetic resonance imaging (MRI) in order to correlate MRI findings with symptomatology. The unaffected hips were also studied. In group A hips, poor congruence of the articular cartilage surfaces was present in three of five cases, whereas good congruence was found in all group B hips. In one spherical but painful hip (group A), MRI revealed a protuberance in the anterolateral cartilage of the femoral head. The joint cartilage in group A and B hips was, on average, 0.5 and 1.5 mm thicker, respectively, than the cartilage in the unaffected hips. The lateral joint capsule was, on average, 3.0 mm thicker in group A hips than in the unaffected hips (P < 0.05), which possibly reflects reactive changes due to chronic irritation in the painful hips. The mean joint capsule thickness differed by only 0.5 mm between the unaffected and group B hips. Mean anterior acetabular coverage by MRI was 97 % in group A and 98 % in group B, while in the unaffected hips mean anterior coverage was 102 %. In an aspherical painful hip, MRI revealed a juxta-articular cyst not visible by radiography. A symptomless intra-articular fragment, due to osteochondritis dissecans, was well visualized with MRI. MRI is recommended for evaluation of pain in hips with late sequelae of Perthes' disease. It may show abnormalities in bony structures, as well as in joint capsule and cartilage. (orig.).

We consider General Relativity with matter, radiation and a minimally coupled dark energy defined by an equation of state w. Using dynamical system method, we find the equilibrium points of such a theory assuming an expanding Universe and a positive dark energy density. Two of these points correspond to classical radiation and matter dominated epochs for the Universe. For the other points, dark energy mimics matter, radiation or accelerates Universe expansion. We then look for possible sequences of epochs describing a Universe starting with some radiation dominated epoch(s) (mimicked or not by dark energy), then matter dominated epoch(s) (mimicked or not by dark energy) and ending with an accelerated expansion. We find ten sequences able to follow this Universe history without singular behaviour of w at some saddle points. Most of them are new in dark energy literature. To get more than these ten sequences, w has to be singular at some specific saddle equilibrium points. This is an unusual mathematical property of the equation of state in dark energy literature, whose physical consequences tend to be discarded by observations. This thus distinguishes the ten above sequences from an infinity of ways to describe Universe expansion.

The Backwith-Wiedemann syndrome (BWS) is and unusual complex with variable clinical features. Major findings included defects in the abdominal wall, macroglossia and macrosomia. These features should be amenable to prenatal ultrasound detection. Serious complications are possible in the neonatal period, which may result from the hypoglycemia or the airway obstruction due to macroglossia. Accurate prenatal diagnosis allows optimum prenatal care and prevention of serious complications. We report a case of prenatally diagnosed BWS with omphalocele, macroglossia, nephromegaly and hepatic cyst.

We wanted to describe the CT findings of small bowel anisakiasis with the pathologic correlation. Four patients with surgically and pathologically proven small bowel anisakiasis were included in this retrospective study. They were three men and one woman and their ages ranged from 28 to 43 years (mean age: 38 years). We evaluated their clinical, CT and histological findings. All the patients had a history of ingesting raw fish within 24 hours from the time of symptom onset. They complained of abdominal pain (n=4), nausea (n=4), vomiting (n=2) and diarrhea (n=1). Physical examination revealed tenderness (n=4), rebound tenderness (n=4) and increased bowel sounds (n=3). Leukocytosis was noted in all the patients on the laboratory examination. None of the patients showed eosinophilia. The CT findings were segmental small bowel wall thickening with preserved layering (n=4), focal segmental luminal narrowing with proximal dilatation (n=4), peritoneal thickening (n=3), mesenteric or omental infiltration (n=4) and varying degrees of ascites (n=4). On the histopathologic examination, they revealed an infiltration of eosinophils (n=4) in all layers of the bowel wall with severe edema. The larvae were found on surgico-pathologic examination in all the cases. The CT findings may be helpful to make the specific diagnosis of small bowel anisakiasis in a patient with the clinical findings of an acute abdomen and a history of eating raw fish

Struma ovarii is ovarian tumor composed solely or predominantly of thyroid tissue or tumor in which hyperthyroidism results from ovarian thyroid tissue, and usually occurs in tandem with cystic teratoma. Ovarian cystic teratoma is radiologically easily diagnosed due to calcification or fat, for example, but the preoperative diagnosis of struma ovarii is often difficult due to rare characteristic features of thyroid tissue. Our purpose was to determine whether there were specific findings of struma ovarii which distinguished it from other ovarian tumors, and this involved analysis of its radiologic findings. Using ultrasonography, computed tomography, and magnetic resonance imaging, preoperative radiologic findings of pathologically-proven struma ovarii in eleven patients were retrospectively evaluated for site, margin, nature (cystic, solid, mixed), contrast enhancement, septa, mural nodule, calcification, fat, and metastasis. These findings were compared with pathologic findings. All eleven tumors were unilateral, ten had smooth tumor margins, seven were mixed cystic and solid tumors (more than 70% of solid components in one tumor), and nine had regular septa. Three of four cystic masses (one unilocular, one bilocular and two multilocular cysts) had mural nodules. Calcifications were found in two tumors, and fat in one. Malignant change or metastasis was not found in any tumor. In one patient with hyperthyroidism due to struma ovarii, symptoms and signs of this subsided after removal of the tumor on salpingo-oophorectomy. Most cases of struma ovarii occurred unilaterally within ovarian teratomas in premenopausal women, and were mixed cystic and solid masses with smooth margins that are commonly enhanced on contrast enhanced scans. In one patient, hyperthyroidism was caused by struma ovarii. There were, however, no specific radiologic findings that were sufficiently typical to suggest the correct preoperative diagnosis of struma ovarii.

Struma ovarii is ovarian tumor composed solely or predominantly of thyroid tissue or tumor in which hyperthyroidism results from ovarian thyroid tissue, and usually occurs in tandem with cystic teratoma. Ovarian cystic teratoma is radiologically easily diagnosed due to calcification or fat, for example, but the preoperative diagnosis of struma ovarii is often difficult due to rare characteristic features of thyroid tissue. Our purpose was to determine whether there were specific findings of struma ovarii which distinguished it from other ovarian tumors, and this involved analysis of its radiologic findings. Using ultrasonography, computed tomography, and magnetic resonance imaging, preoperative radiologic findings of pathologically-proven struma ovarii in eleven patients were retrospectively evaluated for site, margin, nature (cystic, solid, mixed), contrast enhancement, septa, mural nodule, calcification, fat, and metastasis. These findings were compared with pathologic findings. All eleven tumors were unilateral, ten had smooth tumor margins, seven were mixed cystic and solid tumors (more than 70% of solid components in one tumor), and nine had regular septa. Three of four cystic masses (one unilocular, one bilocular and two multilocular cysts) had mural nodules. Calcifications were found in two tumors, and fat in one. Malignant change or metastasis was not found in any tumor. In one patient with hyperthyroidism due to struma ovarii, symptoms and signs of this subsided after removal of the tumor on salpingo-oophorectomy. Most cases of struma ovarii occurred unilaterally within ovarian teratomas in premenopausal women, and were mixed cystic and solid masses with smooth margins that are commonly enhanced on contrast enhanced scans. In one patient, hyperthyroidism was caused by struma ovarii. There were, however, no specific radiologic findings that were sufficiently typical to suggest the correct preoperative diagnosis of struma ovarii

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired disease involving multiple hematopoietic cell lines. Characteristics of PNH are intrinsic hemolytic anemia, iron deficiency anemia and venous thrombosis. We report a case of PNH with characterostoc MR and CT findings. The signal intensity of renal cortex was lower than that of medulla on both T1-and T2-weighted MR imaging. On T2 weighted MR images, the liver showed very low signal intensity but the signal intensity of the spleen was normal. On precontrast CT the attenuation of renal cortex was higher than that of renal medulla and the attenuation of liver was higher than that of the spleen. These findings of MR imaging and CT were the result from the deposition of hemosiderin in the cells of proximal convoluted tubules and transfusional hemosiderosis of liver

Full Text Available Myofibroblastoma of the breast (MFB is a very rare benign stromal tumor. In recent years, increase in mammographic screenings has resulted in increased diagnosis of MFB. Most cases are old males and postmenopausal women. MFB may be confused as malignant, clinically, morphologically, or by imaging. Immunohistochemistry is essential for final diagnosis in these cases. We report a case of a pathologically diagnosed MFB in an 80-year-old male patient who had coexisting prostate cancer and describe its imaging characteristics, especially magnetic resonance imaging (MRI. In this paper, histopathological and MRI findings of the MFB were discussed.

Uterine tumor resembling ovarian sex-cord tumor is a very rare uterine neoplasm that was first described by Clement and Scully in 1976. Since then, approximately 70 cases have been reported. However, these case reports have mainly described and discussed the pathologic and clinical features, and few radiologic findings have been presented. We experienced a case of a uterine tumor resembling ovarian sex-cord tumor, which was considered a uterine leiomyoma or leiomyosarcoma upon initial impression at preoperative evaluation including transvaginal ultrasonography and pelvic magnetic resonance imaging. Its diagnosis was pathologically confirmed after total abdominal hysterectomy.

In November 2009, ten suspicious cases of yellow fever, including six deaths, were notified in the region of Denguélé, in the northwest of Côte-d'Ivoire. In order to evaluate the extent of yellow fever virus circulation and the risk for local people, a mission of entomological investigation was carried out by the Ministry of Health and Public Hygiene of Côte-d'Ivoire. Entomological investigations were conducted in the villages of confirmed cases (Banakoro and Tron-Touba) and the centers of consultation and hospitalization of cases during illness. Breteau index and recipient index were quasi nil. Aedes aegypti was absent among the captured mosquitoes. On the other hand, Aedes luteocephalus and Aedes opok were present at Banakoro and Tron-Touba with respective average biting rates of 0.8 and 0.6 bite/man/twilight. This situation of epidemic in the northwest of Côte-d'Ivoire could be explained by the deterioration of Denguélé region's health system which is a consequence of the war started in the country in 2002 and which has lowered the immunity of the population.

Recently, it has been recognized that pathologically proven progressive supranuclear palsy (PSP) cases are classified into various clinical subtypes with non-uniform symptoms and imaging findings. This article reviews essential imaging findings, general information, and advanced magnetic resonance imaging (MRI) techniques for PSP and presents these MRI findings of pathologically proven typical and atypical PSP cases for educational purposes. With the review of literatures, notably including atypical pathologically proven PSP cases, MRI and clinical information of 15 pathologically proven typical and atypical PSP cases were retrospectively evaluated. In addition to typical symptoms, PSP patients can exhibit atypical symptoms including levodopa-responsive parkinsonism, pure akinesia, non-fluent aphasia, corticobasal syndrome, and predominant cerebellar ataxia. As well as clinical symptoms, the degree of midbrain atrophy, a well-known imaging hallmark, is not consistent in atypical PSP cases. This fact has important implications for the limitation of midbrain atrophy as a diagnostic imaging biomarker of PSP pathology. Additional evaluation of other imaging findings including various regional atrophies of the globus pallidus, frontal lobe, cerebral peduncle, and superior cerebellar peduncle is essential for the diagnosis of atypical PSP cases. It is necessary for radiologists to recognize the wide clinical and radiological spectra of typical and atypical PSP cases. (orig.)

Case finding of patients at risk of COPD by community pharmacists could identify a substantial number of people with undiagnosed COPD, but little is known about the feasibility and effectiveness of pharmacy-based COPD case finding using microspirometry. The objective of this study was to assess the feasibility and effectiveness of COPD case-finding service provided by community pharmacists, utilizing a combination of risk assessment questionnaire and microspirometry. A 6-month service was conducted in 21 community pharmacies in Australia. Pharmacists trained in COPD case finding, including lung function test (LFT), invited their patients aged ≥35 years with a history of smoking and/or respiratory symptoms to participate. High-risk patients were identified via a COPD risk assessment questionnaire (Initial Screening Questionnaire [ISQ]) and underwent LFT. Pharmacists referred patients with a forced expiratory volume in 1 second (FEV 1 )/forced expiratory volume in 6 seconds (FEV 6 ) ratio 3 indicating high COPD risk. Of the 157 patients who were able to complete LFT, 61 (39%) had an FEV 1 /FEV 6 ratio of 3) were at a significantly higher risk of an FEV 1 /FEV 6 ratio of strategy for reducing the burden of COPD, particularly for those living in rural locations.

Venom ophthalmia caused by venoms of spitting elapid and other snakes: report of ten cases with review of epidemiology, clinical features, pathophysiology and management. Chu, ER, Weinstein, SA, White, J and Warrell, DA. Toxicon XX:xxx-xxx. We present ten cases of ocular injury following instillation into the eye of snake venoms or toxins by spitting elapids and other snakes. The natural history of spitting elapids and the toxinology of their venoms are reviewed together with the medical effects and management of venom ophthalmia in humans and domestic animals including both direct and allergic effects of venoms. Although the clinical features and management of envenoming following bites by spitting elapids (genera Naja and Hemachatus) are well documented, these snakes are also capable of "spraying" venom towards the eyes of predators, a defensive strategy that causes painful and potentially blinding ocular envenoming (venom ophthalmia). Little attention has been given to the detailed clinical description, clinical evolution and efficacy of treatment of venom ophthalmia and no clear management guidelines have been formulated. Knowledge of the pathophysiology of ocular envenoming is based largely on animal studies and a limited body of clinical information. A few cases of ocular exposure to venoms from crotaline viperids have also been described. Venom ophthalmia often presents with pain, hyperemia, blepharitis, blepharospasm and corneal erosions. Delay or lack of treatment may result in corneal opacity, hypopyon and/or blindness. When venom is "spat" into the eye, cranial nerve VII may be affected by local spread of venom but systemic envenoming has not been documented in human patients. Management of venom ophthalmia consists of: 1) urgent decontamination by copious irrigation 2) analgesia by vasoconstrictors with weak mydriatic activity (e.g. epinephrine) and limited topical administration of local anesthetics (e.g. tetracaine) 3) exclusion of corneal abrasions

Exogenous lipoid pneumonia is an unusual disease resulting from aspiration of oil particles. A history of oil ingestion strongly suggests the diagnosis, but the radiological presentation varies from mild perihilar consolidation to diffuse and extensive bilateral involvement, particularly of the posterior basal segment of both lower lung. Since magnetic resonance (MR) provides greater contrast resolution than CT, it offers the potential for tissue characterization. In particular, fatty tissue and lipid containing substances are known to have high signal intensities on T1-and T2-weighted spin-echo (SE) images. We report MR findings in two case of exogenous lipoid pneumonia caused by ingestion of shark liver oil (Squalene)

To assess the value of positional shifting to a gravity-dependent area, as revealed by HRCT, in differentiating pulmonary edema (PE) from other conditions. Sixteen consecutive patients in whom plain radiographs suggested the presence of pulmonary edema but the clinical findings were indefinite underwent HRCT of the lung. For initial scanning they were in the supine position, and then in the prone position. Findings of ground-glass opacity, interlobular septal thickening and peribronchovascular interistitial thickening were analyzed in terms of the presence and degree of shifting to a gravity-dependent area, a grade of high, intermediate or low being assigned. PE was diagnosed in 8 of 16 cases, the remainder being designated as non-pulmonary edema (NPE). Ground-glass opacity was observed in all 16, while the degree of positional shifting was found to be high in ten (PE:NPE=6:4), intermediate in four (PE:NPE=2:2), and low in two (PE:NPE=0:2). There was no significant difference between the two groups (ρ > 0.05). Interlobular septal thickening was observed in all but two NPE cases; the degree of shifting was high in six (PE:NPE=6:0), intermediate in one (PE), and low in seven (PE:NPE=1:6). Shifting was significantly more prominent in PE than in NPE case (ρ <0.05). Peribronchovascular interstitial thickening was positive in all PE cases and one NPE case, with no positional shifting. Positional shifting of interlobular septal thickening to a gravity-dependent area, as demonstrated by HRCT, is the most specific indicator of pulmonary edema

Frequency-modulated transcutaneous electrical nerve stimulation (TENS) delivers currents that fluctuate between preset boundaries over a fixed period of time. This study compared the effects of constant-frequency TENS and frequency-modulated TENS on blunt pressure pain in healthy human volunteers. Thirty-six participants received constant-frequency TENS (80 pps), frequency-modulated TENS (20 to 100 pps), and placebo (no current) TENS at a strong nonpainful intensity in a randomized cross-over manner. Pain threshold was taken from the forearm using pressure algometry. There were no statistical differences between constant-frequency TENS and frequency-modulated TENS after 20 minutes (OR = 1.54; CI, 0.29, 8.23, P = 1.0). Both constant-frequency TENS and frequency-modulated TENS were superior to placebo TENS (OR = 59.5, P TENS does not influence hypoalgesia to any greater extent than constant-frequency TENS when currents generate a strong nonpainful paraesthesia at the site of pain. The finding that frequency-modulated TENS and constant-frequency TENS were superior to placebo TENS provides further evidence that a strong yet nonpainful TENS intensity is a prerequisite for hypoalgesia. This study provides evidence that TENS, delivered at a strong nonpainful intensity, increases pain threshold to pressure algometry in healthy participants over and above that seen with placebo (no current) TENS. Frequency-modulated TENS does not increase hypoalgesia to any appreciable extent to that seen with constant-frequency TENS.

Parenchymal iron deposition occurs in hemochromatosis, while iron is deposited in reticuloendothelial cells after blood transfusions(Hemosiderosis). We studied correlation between MR finding and clinical findings(serum ferritin, TSI, LFT, disease duration) of hemosiderosis. 12 patients with chronic renal failure and one patient with aplastic anemia, who have received multiple transfusion, were performed MRI with a 2.0 Tesla unit. In all of 13 patients(17 cases), the liver revealed low signal intensity equal to background noise. In 4 of 17 cases whose serum ferritin level was below 1000 ng/ml, pancreas, gastric wall, adrenal gland were involved in 1 case. In 4 cases with serum ferritin level between 1000 and 1500, pancreas was involved in 2 cases, and other organ was involved in 1 case. In 9 cases with serum ferritin level above 1500ng/ml, pancreas was involved in 9 cases, and other origin 4 cases. The MR findings are well correlated with serum ferritin level whereas the TSI, LFT, disease duration are not correlated with involved organ on MR.

A characteristic initial sign of CT findings, as seen in cases of subdural hematoma (SDH) after cardiovascular surgery, was reported. Central-nervous-system (CNS) complications after cardiovascular surgery have been thought to be due mainly to the ischemic brain damage caused by both reduced cerebral perfusion pressure and microembolism during extracorporeal circulation. However, we observed 8 cases of SDH in 39 patients suffering from major CNS complications after cardiovascular surgery. In view of these experiences, SDH was thought to be one of the most significant factors causing CNS complications after cardiovascular surgery. In the sequential CT scans of 8 cases of SDH, four exhibited a typical, small, spotty high-density area in the early period of SDH. The clinical courses of these four patients were relatively acute or subacute, and the initial small high-density area progressed to definite SDH findings in that region in the follow-up CT. These initial findings of CT scans were regarded as ''initial signs of SDH-ISS-''. Although there have been many reports concerning the sequential CT changes in SDH, there has been no report describing the above-mentioned finding. It was emphasized that ''ISS'' is of great importance in the early management for SDH.

The determine the chest CT findings in breast cancer patients who have undergone postoperative irradiation. The chest CT findings in 36 female patients who underwent breast surgery and radiotherapy between May 1996 and March 2000 were rerospectively analysed. Prior to radiotheraphy, baseline chest CT depicted normal parenchyma in all cases. In 11 patients, the ipsilateral breast and chest wall were irradiated using opposed tangential fields, while 25 were treated by the four fields method (opposed tangential fields plus anterior and posterior supraclavicular/high axillary fields), with a total dose of 5040-5400 cGy for 5-9 weeks. CT after radiotherapy demonstrated reticular opacity (n=24), perpendicular linear opacity (n=15), traction bronchiectasis (n=7), consolidation (n=6), ground glass attenuation (n=3), pathologic rib fractures (n=3) pleural effusion (n=2), and pleural thickening (n=1), while in five patients no abnormality was observed. in addition, in the anterolateral lung area of 23 (64%) of 36 patients who underwent tangential beam irradiation, CT demonstrated peripheral opacities. When supraclavicular and axillary portals were used, radiation-induced lung changes mostly occurred at the apex of the lung (n=24). Chest radiographs were abnormal in 26 patients and normal in ten; in five of these ten, CT demonstrated reticular opacity. Depending on the irradiation CT findings of radiation-induced lung injury in breast cancer include areas of increased opacity with or without fibrosis, in apical and/or anterior subpleural regions. CT may help differentiate radiation-induced parenchymal change from superimposed or combined lung disease.

The synovial hemangioma is an uncommon benign vascular tumor that is difficult to diagnose on the basis of clinical signs Moreover, it has no characteristic radiographic features. The objective of the present report was to describe the MR findings associated with synovial hemangioma of the knee. We review the clinical and MR findings in six patients, with histologically confirmed synovial hemangioma of the Knee, studied with different MR systems and techniques. Synovial hemangiomas were isointense with respect to muscle in T1-weighted images, strongly hyperintense in T2-weighted sequences and presented wavy hypointense linear images. Gadolinium administration resulted in a marked enhancement, although it was heterogeneous in two of three cases analyzed. Although the findings are not pathognomonic, the presence of an intraarticular tumor of the knee that is isointense with respect to muscle in T1 and hyperintense in T2, and shows wavy hypointense images and a marked contrast uptake, may suggest the presence of synovial hemangioma.

Full Text Available Abstract Background Engagement of communities and civil society organizations is a critical part of the Post-2015 End TB Strategy. Since 2007, many models of community referral have been implemented to boost TB case detection in Nigeria. Yet clear insights into the comparative TB yield from particular approaches have been limited. Methods We compared four models of active case finding in three Nigerian states. Data on presumptive TB case referral by community workers (CWs, TB diagnoses among referred clients, active case finding model characteristics, and CWs compensation details for 2012 were obtained from implementers and CWs via interviews and log book review. Self-reported performance data were triangulated against routine surveillance data to assess concordance. Analysis focused on assessing the predictors of presumptive TB referral. Results CWs referred 4–22 % of presumptive TB clients tested, and 4–24 % of the total TB cases detected. The annual median referral per CW ranged widely among the models from 1 to 48 clients, with an overall average of 13.4 referrals per CW. The highest median referrals (48 per CW/yr and mean TB diagnoses (7.1/yr per CW (H =70.850, p < 0.001 was obtained by the model with training supervision, and $80/quarterly payments (Comprehensive Quotas-Oriented model. The model with irregularly supervised, trained, and compensated CWs contributed the least to TB case detection with a median of 13 referrals per CW/yr and mean of 0.53 TB diagnoses per CW/yr. Hours spent weekly on presumptive TB referral made the strongest unique contribution (Beta = 0.514, p < 0.001 to explaining presumptive TB referral after controlling for other variables. Conclusion All community based TB case-finding projects studied referred a relative low number of symptomatic individuals.

Globally, almost 40% of tuberculosis (TB) patients remain undiagnosed, and those that are diagnosed often experience prolonged delays before initiating correct treatment, leading to ongoing transmission. While there is a push for active case finding (ACF) to improve early detection and treatment of TB, there is extremely limited evidence about the relative cost-effectiveness of different ACF implementation models. Cambodia presents a unique opportunity for addressing this gap in evidence as ACF has been implemented using different models, but no comparisons have been conducted. The objective of our study is to contribute to knowledge and methodology on comparing cost-effectiveness of alternative ACF implementation models from the health service perspective, using programmatic data, in order to inform national policy and practice. We retrospectively compared three distinct ACF implementation models - door to door symptom screening in urban slums, checking contacts of TB patients, and door to door symptom screening focusing on rural populations aged above 55 - in terms of the number of new bacteriologically-positive pulmonary TB cases diagnosed and the cost of implementation assuming activities are conducted by the national TB program of Cambodia. We calculated the cost per additional case detected using the alternative ACF models. Our analysis, which is the first of its kind for TB, revealed that the ACF model based on door to door screening in poor urban areas of Phnom Penh was the most cost-effective (249 USD per case detected, 737 cases diagnosed), followed by the model based on testing contacts of TB patients (308 USD per case detected, 807 cases diagnosed), and symptomatic screening of older rural populations (316 USD per case detected, 397 cases diagnosed). Our study provides new evidence on the relative effectiveness and economics of three implementation models for enhanced TB case finding, in line with calls for data from 'routine conditions' to be included

Retinal hemorrhage is a well-recognized manifestation of child abuse found in many babies with shaken baby syndrome. The presence of retinal hemorrhage is generally associated with more severe neurological damage and a worse clinical outcome. MR imaging findings of retinal hemorrhages are not well described in the pediatric literature. We present a 6-month-old boy with new-onset seizures, subdural hemorrhage and bilateral retinal hemorrhages that were detected by MRI and confirmed by indirect ophthalmoscopy. This case demonstrates the MR imaging findings of retinal hemorrhages and the importance of radiologists being able to recognize these specific imaging features. (orig.)

Three cases of clinically definite multiple sclerosis manifested homonymous hemianopsia. A 35-year-old female, in whom right optic neuritis developed as the initial symptom, manifested right homonymous hemianopsia 4 months later followed by cerebral symptoms another 4 months later. A 25-year-old male developed sudden brain stem and cerebellar symptoms associated with right abducens palsy and right homonymous hemianopsia. In a 26-year-old female developed right homonymous hemianopsia 13 years after the first attack of recurrent optic neuritis. CT-scan in these three cases revealed the presence of a ''plaque'' located in the white matter of the left occipital lobe in cases 1 and 2 and in the left peririgone white matter in case 3 as the causative lesion for the right homonymous hemianopsia. These findings indicate that the optic radiation may be involved in multiple sclerosis resulting in homonymous hemianopsia. CT scan is of value in determining the location of the affected intracranial lesion in multiple sclerosis. (author)

A case of remitting-relapsing Bickerstaff encephalitis is reported. The article focuses on its imaging findings and their significance when a clinical differentiation between Bickerstaff encephalitis and Miller-Fisher syndrome is attempted. Signs and symptoms may occasionally overlap. However, because Miller-Fisher syndrome is related to the peripheral nervous system and Bickerstaff encephalitis is a central disease, the recognition of brain stem hypointense lesions on T1-weighted images, which are hyperintense on T2-weighted sequences, could be a reliable tool when the clinical diagnosis is unclear.

Transcutaneous electrical nerve stimulation (TENS) reduces hyperalgesia and pain. Both low frequency (LF) and high frequency (HF) TENS, delivered at the same intensity (90% motor threshold (MT)) daily, result in analgesic tolerance with repeated use by the 5th day of treatment. Thecurrentstudytestedif 1) increasingintensityby 10% per daypreventsthedevelopmentoftolerance to repeated TENS, and 2) iflowerintensity TENS (50 % MT) produces an equivalentreduction in hyperalgesia when compared to 90% MT TENS. Sprague-Dawley rats with unilateral knee joint inflammation (3% carrageenan) were separated according to the intensity of TENS used: Sham, 50% LF, 50% HF, 90% LF, 90% HF, and increased intensity by 10% per day (LF and HF). The reduced mechanical withdrawal threshold following the induction of inflammation was reversed by application of TENS applied at 90% MT and increasing intensity for the first 4 days. On the 5th day, the groups that received 90% MT intensity showed tolerance. Nevertheless, the group that received an increased intensity on each day still showed a reversal of the mechanical withdrawal threshold with TENS. These results show that the development of tolerance can be delayed by increasing intensity of TENS. PMID:22858165

Cystic fibrosis is a hereditary disease involving recessive transmission. The fundamental abnormality consists of the production of abnormal secretion from a variety of exocrine glands such as salivary and sweat glands and those of the pancreas, colon, and tracheobronchial trees. Cystic fibrosis is the most common lethal genetically transmitted disease among whites, but is uncommon in Asians, including Koreans. Although a case involving a Korean was reported in 1988, the focus was diagnosis rather than the radiological findings. In the case of cystic fibrosis we now describe, the focus is inverted: we emphasise the reported in 1988, focusing on radiologic findings

Xanthogranulomatous pyelonephritis (XGNP) is an uncommon condition characterized by chronic suppurative renal inflammation that leads to progressive parenchymal destruction. This condition can clinically present as recurrent urinary tract infections, flank pain, hematuria, and occasionally sepsis, and weight loss. This condition is usually associated with obstructing renal calculus. We present 18-fluorodeoxyglucose positron emission tomography-computed tomography (18-FDG PET/CT) findings in an elderly male suffering from pyrexia and weight loss and suspected urinary tract infection. PET/CT findings in this case lead to diagnosis of XGNP. This diagnosis should be kept in mind while evaluating similar symptoms and PET/CT scan findings. PMID:24019680

Nevirapine (NVP) is used in developing countries as first-line treatment of HIV infection. Unfortunately, its use is associated with common serious adverse drug reactions, such as liver toxicity and the most severe and rare Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). GSTT1 and GSTM1 genes code for enzymes involved in the metabolism of a wide range of drugs. We hypothesized that this gene variability could be implicated in NVP adverse reactions. We analyzed the GSTM1 and GSTT1 null genotypes by multiplex PCR in a population of 181 patients from Mozambique, treated with NVP. A case/control association study was performed. We also counted the number of risk alleles in SJS/TEN patients and in controls, including the GSTM1 null genotype and four previously identified risk alleles in CYP2B6, HCP5, and TRAF3IP2 genes. Among patients, 27 had developed SJS/TEN and 76 had developed hepatotoxicity during the treatment. The GSTM1 null genotype was more frequent in the cases with SJS/TEN than in the controls (OR = 2.94, P = 0.027). This association is also observed when other risk factors are taken into account, by a multivariate analysis (P = 0.024 and OR = 3.58). The risk allele counting analysis revealed a significantly higher risk for SJS/TEN in patients carrying three or four risk alleles. Moreover, all subjects with five or six risk alleles developed SJS/TEN, while subjects without any risk alleles were present only in the control group. We observed an association between GSTM1 and SJS/TEN susceptibility. Moreover, GSTM1 contributes to the definition of a genetic risk profile for SJS/TEN susceptibility.

Hawassa Prison, Southern Region of Ethiopia. To determine the burden of pulmonary tuberculosis (TB) using active case finding among prisoners. In this cross-sectional study, prisoners were screened for TB using a symptom screen. Those with cough of 2 weeks had spot and morning sputum samples collected for acid-fast bacilli (AFB) smear microscopy and molecular diagnostic testing (Xpert® MTB/RIF). Among 2068 prisoners, 372 (18%) had a positive cough screen. The median age of these 372 persons was 23 years, 97% were male and 63% were from urban areas. Among those with a positive symptom screen, 8 (2%) were AFB sputum smear-positive and 31 (8%) were Xpert-positive. The point prevalence of pulmonary TB at the prison was 1748 per 100 000 persons. In multivariate analysis, persons with cough >4 weeks were more likely to have TB (OR 3.34, 95%CI 1.54-7.23). A high prevalence of TB was detected among inmates at a large Ethiopian prison. Active case finding using a cough symptom screen in combination with Xpert had high utility, and has the potential to interrupt transmission of Mycobacterium tuberculosis in correctional facilities in low- and middle-income, high-burden countries.

Radiation-induced spinal cord gliomas are extremely rare. Since the first case was reported in 1980, only six additional cases have been reported.; The radiation-induced gliomas were related to the treatment of Hodgkin's lymphoma, thyroid cancer, and medullomyoblastoma, and to multiple chest fluoroscopic examinations in pulmonary tuberculosis patient. We report a case of radiation-induced spinal cord glioblastoma developed in a 17-year-old girl after a 13-year latency period following radiotherapy for nasopharyngeal rhabdomyosarcoma. MRI findings of our case are described.

Prevalence of Tuberculosis among Household Contacts in Pondicherry: Active Case Finding Among New Smear Positive Cases

Directory of Open Access Journals (Sweden)

Kumar VA

2016-05-01

Full Text Available Introduction: The risk of transmission from the index case to its contacts is more in case of smear positive Pulmonary Tuberculosis cases. Any delay in diagnosis and treatment increases the risk of disease transmission to their contacts. Contact screening is important for early detection of transmission of infection. Thus, active case finding of TB is needed to identify the case yield among household contacts. This study will yield the burden of Tuberculosis among the household contact. Objective: To identify the TB suspect and estimate the prevalence of TB among household contacts. Material and Methods: A two stage cross study was done in 472 households of 157 ‘Index cases’ registered in the State Tuberculosis Unit, Puducherry. The study duration was one year and eight months. Data was entered and analyzed by using Epi_Info (Version 3.4.3 software package. Results: A total of 96 (20.3% symptomatic was found from the 472 households contacts who participated in this study. Out of 90 symptomatics, 70 (72.9% were symptomatic within two months of visit and 26 (27.1% were found to have symptoms after eight months. The overall prevalence of tuberculosis in symptomatic household contacts was 4.3% and all tuberculosis confirmed cases were found at the end of in second month only. Conclusion: Considering the prevalence tuberculosis among the symptomatic of household contact to be 4.3%, their investigation to rule out TB in earlier stages is a need. It may help prevent further spread of M. tuberculosis infection in the local community.

The Proceedings of the ten Detonation Symposia have become the major archival source of information of international research in explosive phenomenology, theory, experimental techniques, numerical modeling, and high-rate reaction chemistry. In many cases, they contain the original reference or the only reference to major progress in the field. For some papers, the information is more complete than the complementary article appearing in a formal journal; yet for others, authors elected to publish only an abstract in the Proceedings. For the large majority of papers, the Symposia Proceedings provide the only published reference to a body of work. This report indexes the ten existing Proceedings of the Detonation Symposia by paper titles, topic phrases, authors, and first appearance of acronyms and code names.

Most common breast cancer susceptibility variants have been identified through genome-wide association studies (GWAS) of predominantly estrogen receptor (ER)-positive disease1. We conducted a GWAS using 21,468 ER-negative cases and 100,594 controls combined with 18,908 BRCA1 mutation carriers (9,414 with breast cancer), all of European origin. We identified independent associations at P < 5 × 10−8 with ten variants at nine new loci. At P < 0.05, we replicated associations with 10 of 11 variants previously reported in ER-negative disease or BRCA1 mutation carrier GWAS and observed consistent associations with ER-negative disease for 105 susceptibility variants identified by other studies. These 125 variants explain approximately 14% of the familial risk of this breast cancer subtype. There was high genetic correlation (0.72) between risk of ER-negative breast cancer and breast cancer risk for BRCA1 mutation carriers. These findings may lead to improved risk prediction and inform further fine-mapping and functional work to better understand the biological basis of ER-negative breast cancer. PMID:29058716

Ataxic hemiparesis is described as a syndrome in which pyramidal and cerebellar signs occur ipsilaterally. Fisher who suggested the designation ''ataxic hemiparesis'' for this syndrome confirmed by pathological study that causative lesion was in the basis pontis at the level of the junction of the upper one third and lower two thirds on the opposite side of the neurological deficit and he also reported that CT might fail to show the lesion. We observed 4 patients with ataxic hemiparesis and examined them in auditory brainstem response (ABR), somatosensory evoked potential (SEP), and blink reflex as electrophysiological study. Their CT and electrophysiological findings were compared with each others to define the responsible lesion more clearly. Essentially, these abnormal electrophysiological findings were recognized only in the case of pontine hemorrhage, and these findings recovered to normal as clinical and CT findings were improved. In the other cases, the electrophysiological findings were not prominent and CT revealed the lesions in deep frontal region, internal capsule and cerebellar hemispheres respectively. These results might show that many cases of extra-pontine lesions could develop the syndrome of ataxic hemiparesis. However, the relation between responsible lesions for ataxic hemiparesis and electrophysiological findings are still uncertain. Further evidences including clinicopathological studies will be required to clarify this relation and to get the more accurate anatomical interpretation of ataxic hemiparesis from lesions besides the pontine region.

The quantum probability functions are calculated for ten-dimensional compact baby universe model. The authors find that the probability for the Yang-Mills baby universe to undergo a spontaneous compactification down to a four-dimensional spacetime is greater than that to remain in the original homogeneous multidimensional state. Some questions about large-wormhole catastrophe are also discussed

This study is to describe authors' experience on mammographic findings of breast cancer and to know if there is difference between 35 years of age or younger and older groups. Mammograms of 72 patients with breast cancer detected from January, 1991 to December, 1993 were retrospectively analysed. Mammographic findings were classified into mass only, mass with microcalcifications, microcalcifications only and others. Marginal characteristics of mass were classified into spiculated, poorly marginated and well marginated. Shape of microcalcifications were classified into casting, granular and mixed types. These findings were compared between 35 years of age or younger and older groups. Mammogram showed mass only in 33 patients (46%), mass with microcalcifications in 26 patients (36%), microcalcifications only in seven (10%) and other findings in six (8%). Other findings were architectural distortion, asymmetric high density and incidental breast carcinoma from paraffinoma in one patient respectively, and dense breast in three patients. The margins of the breast mass were spiculated in ten (17%). poorly marginated in 30 (51%), well-marginated in 19 (32%). Shape of microcalcifications were casting type in 13 (40%). granular in 14 (42%) and mixed in six (18%) cases. 3 patients had dense breast with which mammography did not demonstrate the lesion. 3 patients without mammographically demonstrable lesions due to dense breasts were under 35 years in age, and there was statistically significant difference between the two groups (ρ -value < 0.05). Microcalcifications only was more common findings in 35 years of age or younger. The most important mammographic findings of breast cancer were mass and microcalcifications. Architectural distortion and asymmetric high density were additional findings. In 35 years of age or younger, microcalcifications only was an important finding because mass lesions are frequently masked by dense breast. Thus other imaging modalities, such as

To evaluate the patterns of injuries and frequency of associated findings on MR imaging in patients with both anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL)tears;to compare the associated findings, as seen on MR imaging, in cases with both ACL and PCL tears with those with ACL or PCL tears. Ten patients with compbined ACL and PCL tears, 16 with ACL tears and 18 with PCL tears, all confirmed by arthroscopy or open surgery, were involved in this study. To identify the associated knee injuries, MR images were retrospectively evaluated. In ten patients with combined ACL and PCL tears, open surgery led to the identification of six complete ACL tears (60%), four partial ACL tears (40%), eitht complete PCL tears (80%) and two partial PCL tears (20%). Injuries associated with these combined tears, and revealed by MR imaging, comprised six medial collateral ligament injuries (60%), six lateral collateral ligament jnjuries (60%), five medial meniscal injuries (50%), three lateral meniscal injuries (30%), nine bony injuries (90%), two posterior capsular injuries (20%), and three popliteus muscle injuries (30%). The frequency of popliteus muscle injury was significantly different (p<0.05, Fisher's exact test) between the group with both ACL and PCL tears and that with ACL or PCL tears. Associated findings in patients with combined ACL and PCL tears are more frequent than in those with ACL or PCL tears. In cases involving combined ACL and PCL tears, associated findings-as seen on MR images-should thus be carefully examined

Since 2010, the World Health Organization has been recommending that all suspected cases of malaria be confirmed with parasite-based diagnosis before treatment. These guidelines represent a paradigm shift away from presumptive antimalarial treatment of fever. Malaria rapid diagnostic tests (mRDTs) are central to implementing this policy, intended to target artemisinin-based combination therapies (ACT) to patients with confirmed malaria and to improve management of patients with nonmalarial fevers. The ACT Consortium conducted ten linked studies, eight in sub-Saharan Africa and two in Afghanistan, to evaluate the impact of mRDT introduction on case management across settings that vary in malaria endemicity and healthcare provider type. This synthesis includes 562,368 outpatient encounters (study size range 2,400-432,513). mRDTs were associated with significantly lower ACT prescription (range 8-69% versus 20-100%). Prescribing did not always adhere to malaria test results; in several settings, ACTs were prescribed to more than 30% of test-negative patients or to fewer than 80% of test-positive patients. Either an antimalarial or an antibiotic was prescribed for more than 75% of patients across most settings; lower antimalarial prescription for malaria test-negative patients was partly offset by higher antibiotic prescription. Symptomatic management with antipyretics alone was prescribed for fewer than 25% of patients across all scenarios. In community health worker and private retailer settings, mRDTs increased referral of patients to other providers. This synthesis provides an overview of shifts in case management that may be expected with mRDT introduction and highlights areas of focus to improve design and implementation of future case management programs.

Full Text Available CONTEXT: Primary central nervous system lymphomas (PCNSL are a rare subgroup of lymphomas generally associated with HIV and EBV. OBJECTIVE: To study ten autopsy cases of PCNSL, to describe the neuropathological findings, to characterize the phenotype of the neoplastic cells, to detect EBV in the lesion and to compare the findings with the clinical and laboratory data of the patients. METHOD: The clinical, histological and immunohistochemical data of ten cases of PCNSL, eight cases from patients with AIDS, identified among 265 autopsies of these patients were analyzed. RESULTS: Seven patients were males and the mean age was 40.9 years. The most frequent symptomatology was focal neurologic deficit (70%. Six patients presented with only one lesion. Histologically, densely cellular and polymorphous neoplasms with angiocentrism were observed, in 90% of cases. An association with other diseases was observed in four cases. Most patients had diffuse large B cell non-Hodgkin’s lymphoma. EBV was detected by immunohistochemistry in only one case. The lack of detection of the virus might have been due to the long time of fixation of the brain which might have inactivate epitopes therefore compromising the testing. CONCLUSION: In the present series, PCNSL presented with focal symptoms, with unifocal or multifocal lesions, with a predominant B-cell CD20 positive phenotype, rarely associated with EBV.CONTEXTO: Linfoma primário do sistema nervoso central (LP-SNC é raro subgrupo de linfomas relacionado à AIDS, geralmente associado EBV.

Transcutaneous nerve stimulation (TENS) has been proposed as a means of reducing pain in labour. The TENS unit emits low-voltage electrical impulses which vary in frequency and intensity. During labour, TENS electrodes are generally placed on the lower back, although TENS may be used to stimulate acupuncture points or other parts of the body. The physiological mechanisms whereby TENS relieves pain are uncertain. The TENS unit is frequently operated by women, which may increase sense of control in labour. To assess the effects of TENS on pain in labour. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (November 2008). Randomised controlled trials comparing women receiving TENS for pain relief in labour versus routine care, alternative pharmacological methods of pain relief, or placebo devices. We included all types of TENS machines. Two review authors assessed for inclusion all trials identified by the search strategy, carried out data extraction and assessed risk of bias. We have recorded reasons for excluding studies. The search identified 25 studies; we excluded six and included 19 studies including 1671 women. Fifteen examined TENS applied to the back, two to acupuncture points and two to the cranium. Overall, there was little difference in pain ratings between TENS and control groups, although women receiving TENS to acupuncture points were less likely to report severe pain (risk ratio 0.41, 95% confidence interval 0.32 to 0.55). The majority of women using TENS said they would be willing to use it again in a future labour. Where TENS was used as an adjunct to epidural analgesia there was no evidence that it reduced pain. There was no consistent evidence that TENS had any impact on interventions and outcomes in labour. There was little information on outcomes for mothers and babies. No adverse events were reported. There is only limited evidence that TENS reduces pain in labour and it does not seem to have any impact (either positive or

TENS to the Lateral Aspect of the Knees During Stance Attenuates Postural Sway in Young Adults

Full Text Available Somatosensory input is known to be essential for postural control. The present study examined the effects on postural sway of sensory input delivered via transcutaneous electrical nerve stimulation (TENS applied to the knees during stance. Electrodes from a dual-channel portable TENS unit were adhered to the skin overlying the lateral and medial aspect of both knees of 20 young healthy volunteers (mean age 24.0 years, standard deviation 4.0. Postural sway parameters were obtained during static bipedal stance with an AMTI force platform. Four stimulation conditions were tested with eyes open and with eyes closed: no TENS; TENS applied bilaterally; and TENS applied to either the right or the left knee. Participants underwent two eight-trial blocks, with each trial lasting 30 seconds. The order of conditions was randomized for each participant. Stimulation consisted of a biphasic symmetrical stimulus delivered at the sensory detection level, with a pulse duration of 200μsec and a pulse frequency of 100Hz. The application of TENS induced significant reductions in mean sway velocity and in the medio-lateral dispersion of the center of pressure, with no corresponding effect on the anterior-posterior dispersion. These findings suggest that electrical stimulation delivered at the sensory detection level to the lateral aspects of the knees may be effective in improving balance control, and that this effect may be directionally specific.

Objective: Solid pseudopapillary tumor of the pancreas (SPTP tumor) is a rare pancreatic neoplasm with low malignant potential, which usually affects female patients in the second or third decades of life. It is a non-functional, slow-growing neoplasm that very often reaches considerable size before the first symptoms appear. Symptomatology is frequently related to tumor size. Surgical excision is usually curative in most cases. Infrequently the tumor can appear in male patients or in aged women, which can make the diagnosis more difficult. Some patients develop liver metastases in the follow-up that can be resected. Our purpose is to review the radiological and pathological findings of SPTP with emphasis on these infrequent cases. Subjects and methods: The medical records and radiological findings of patients who underwent surgery for SPTP between 2000 and 2005 were retrospectively reviewed. Study eligibility required that patients had undergone surgical resection and that a SPTP had been pathologically proved. Results: Four cases of solid pseudopapillary tumor of the pancreas were diagnosed and treated in our institution in the study period. Two of the patients, developed on follow-up liver metastases, and peritoneal, hepatic, and nodal metastases, respectively. Conclusion: Solid pseudopapillary tumors are well-encapsulated neoplasms that usually have a good prognosis after surgical excision. A malignant behavior is uncommon and in this case lymph node involvement, hepatic metastases and occasionally peritoneal invasion may also occur. Resection of liver metastases can prolong the long-term survival of the patients

To evaluate the CT findings of pulmonary tuberculosis in patients with diabetes mellitus (MD),according to the diabetic control state. Materials and Methods: We retrospectively studied 34 cases of pulmonary tuberculosis accompanied by DM. We divided the right lung three lobes and ten segments and the left into two lobes and eight segments and analyzed CT findings of bronchogenic spread, cavitary lesion, ill-defined nodule, lobular consolidation, lobar and segmental consolidation, atelectasis, interlobular septal thickening, fibrotic band, and associated findings such as lymph node enlargement, pleural effusion and empyema. We also tried to determine the typical CT findings of pulmonary tuberculosis according to diabetic duration and controlled state of DM focusing by FBS 160 and HbA1C 8.0. Results: Among 34 CT scans, bronchogenic spread was seen on 29 (85.3%), cavitary lesion on 26 (76.5%), ill-defined nodules on 11 (32.4%), lobular consolidation on 14 (41.2%), lobar and segmental consolidation on 12 (35.3%), atelectasis on four (14.7%), and fibrotic band on eight (23.5%). Multiple cavities were present in 76.9% of total cavitary lesions, and consolidation with bronchogenic spread in 75%; associated findings were as follows: lymph node enlargement (n=1), pleural effusion (n=10), empyema (n=2), and pericardial effusion (n=2). In 46.7% of cases, general tubercular lesions were in an unusual location, but among cases of secondary pulmonary tuberculosis, 73.9% of lesions were in the usual location. More lobular consolidation was seen in patients with less than FBS 160 on admission, and this result was statistically significant (p<0.05); CT findings did not, however, differ according to diabetic duration and HbA1C. Conclusion: In patients with DM,general fubercular lesions were found infrequently, but in secondary tubereulosis, multiple cavitary lesions-in the usual location-were very frequent. In patients with DM, CT findings of pulmonary tuberculosis did not vary

Extraskeletal Ewing's sarcoma is a rare malignant soft tissue tumor, classified within the Ewing's Sarcoma Family Tumors. While the classical Ewing's Sarcoma affects mainly the bone during youth, the Extraskeletal histotype differs for age incidence, primary location and prognosis. Peak incidence and typical location are during adolescence and in the extremities respectively. We report a 30 year old woman case with a positive outcome after ten years from first diagnosis of Extraskeletal Ewing's sarcoma. Treatment was achieved through surgical resection plus adjuvant chemoradiotherapy derived from EW93 and IRS III trials. Conclusion. Our report represents an unusual case due to age of presentation, neoplasm location and long survival reached. In last decades several trials results demonstrated that long survival could be achieved by combined surgery and adjuvant multi-drug treatment.

Highlights: • We clinicopathologically reviewed 22 cases of early mucinous adenocarcinoma. • Radiologically, all cases showed solid or part-solid nodules. • Lobular-bounded margins were observed in 7 cases. • The radiological features could be histologically attributed to mucin production. • One-third of the cases were preoperatively misdiagnosed as inflammatory nodules. - Abstract: Background: The pathological criteria of early-stage mucinous adenocarcinoma of the lung have recently been defined; however, its characteristic radiologic imaging findings are still poorly understood. Thus, this study aimed to clarify the radiologic and pathological findings of early-stage mucinous adenocarcinoma. Materials and methods: In this study, we clinicopathologically reviewed 22 cases of surgically resected mucinous adenocarcinoma in situ (AIS) and minimal invasive adenocarcinoma (MIA), and attempted to elucidate the characteristic radiologic features of early mucinous adenocarcinomas using high-resolution computed tomography (HRCT). Results: Radiologically, the mean value of the maximum diameter of 22 tumours was 2.1 cm (range, 1.0–2.9 cm). Based on the HRCT findings, the tumours were divided into part-solid ground glass nodules (n = 11) and solid nodules (n = 11). The mean CT attenuation value was 25.7 HU (range, 17–35 HU). All tumours, except 3 tumours pathologically diagnosed as AIS, showed air-containing features. According to the preoperative CT findings, 7 (35%) cases were diagnosed as inflammatory nodules. Of these, 4 cases had lobular-bounded margins, and 3 showed vaguely outlined ground glass shadows. Conclusion: The characteristic HRCT findings of mucinous AIS and MIA were solid or part-solid nodules with air-containing spaces. However, some AIS and MIA nodules showed lobular-bounded margins or marginally vaguely outlined ground glass shadows, and were difficult to differentiate from inflammatory nodules.

Gorlin-Goltz syndrome is an infrequent multi-systemic disease which is characterized by multiple keratocysts in the jaws, calcification of falx cerebri, and basal cell carcinomas. We report a case of Gorlin-Goltz syndrome in a 23-year-old man with emphasis on image findings of keratocyctic odontogenic tumors (KCOTs) on panoramic radiograph, computed tomography, magnetic resonance (MR) imaging, and Ultrasonography (US). In this case, pericoronal lesions were mostly orthokeratinized odontogenic cyst (OOC) concerning the MR and US study, which tended to recur less. The aim of this report was to clarify the characteristic imaging features of the syndrome-related keratocysts that can be used to differentiate KCOT from OOC. Also, our findings suggested that the recurrence rate of KCOTs might be predicted based on their association to teeth.

Logic and technical subjects require students to understand basic knowledge in mathematic. For instance, addition, minus, division and multiplication operations need to be mastered by students due to mathematic complexity as the learning mathematic grows higher. Weak foundation in mathematic also contribute to high failure rate in mathematic subjects in schools. In fact, students in primary schools are struggling to learn mathematic because they need to memorize formulas, multiplication or division operations. To date, this study will develop a puppet prototyping for learning mathematic for six to ten digits multiplication. Ten participants involved in the process of developing the prototype in this study. Students involved in the study were those from the intermediate class students whilst teachers were selected based on their vast knowledge and experiences and have more than five years of experience in teaching mathematic. Close participatory analysis will be used in the prototyping process as to fulfil the requirements of the students and teachers whom will use the puppet in learning six to ten digit multiplication in mathematic. Findings showed that, the students had a great time and fun learning experience in learning multiplication and they able to understand the concept of multiplication using puppet. Colour and materials of the puppet also help to attract student attention during learning. Additionally, students able to visualized and able to calculate accurate multiplication value and the puppet help them to recall in multiplying and adding the digits accordingly.

We report here on two cases of ruptured epidermal inclusion cysts in the subareolar area, which is a very unusual location for these cysts and these lesions can be mistaken for breast malignancies. Although the epidermal inclusion cyst is an uncommon finding in the breast, we can easily diagnosis this as a cyst. But when it is presented in an unusual subareolar location and with a ruptured state, it can be mistaken for breast malignancy. We present here two surgically confirmed cases of ruptured epidermal inclusion cyst in a subareolar location, and this has not been previously described in the English medical literature. In our cases, we first considered the possibility of breast malignancy because the masses presented as an irregular mass on the initial sonography, and the patients were over the age 40 and we didn't take the possibility of abscess from ruptured epidermal inclusion cyst into consideration due to its rare occurrence and the unusual lesion location. FNAB and follow up imaging study after medical treatment, or the recurrent feature were the ways to later narrow the differential diagnosis. In conclusion, when a subareolar lesion has findings on sonography that are suspicious of malignancy, the differential diagnosis should include a ruptured epidermal inclusion cyst, with or without evidence of inflammation.

The imaging findings of complex fibroadenoma have been rarely reported even though the risk of developing breast carcinoma in a patient with complex fibroadenoma is higher than that for a patient with simple fibroadenoma. We reviewed the imaging features and pathologic findings of complex fibroadenomas. Between April 2003 and April 2010, the mammographic and sonographic findings of five patients with complex fibroadenomas were retrospectively reviewed according to the Breast Imaging Reporting and Data System (BIRADS). The pathologic findings were retrospectively reviewed for all 5 patients. The mammography findings showed masses (3 cases) and asymmetry (1 case). On ultrasonography, complex echo patterns were noted in all the patients, and all the lesions were assigned to BI-RADS category 4, suspicious for abnormality. The complex echoic patterns showed two types: 1) a mixture of a heterogeneous hypoechoic central portion and a fuzzy hyperechoic peripheral area in 2 cases, 2) a mixture of tiny anechoic and hypoehoic lesions in 3 cases. Multiple cystic changes were noted in all the cases on the pathologic analysis. Complex fibroadenomas showed different ultrasonographic findings from simple fibroadenomas such as two types of complex echo patterns, even though the other findings were similar to those of simple fibroadenoma. Cystic changes were noted in all the cases on the pathologic analysis. Awareness of these imaging findings will help us to properly diagnose complex fibroadenoma

We assessed the effect of an active case finding (ACF) project on tuberculosis (TB) case notification and the yields from a household and neigbourhood intervention (screening contacts of historical index TB patients diagnosed >24months ago) and a community intervention (screening attendants of health education sessions/mobile clinics). Cross-sectional analysis of project records, township TB registers and annual TB reports. In the household and neigbourhood intervention, of 56,709 people screened, 1,076 were presumptive TB and 74 patients were treated for active TB with a screening yield of 0.1% and a yield from presumptive cases of 6.9%. In the community intervention, of 162,881 people screened, 4,497 were presumptive TB and 984 were treated for active TB with a screening yield of 0.6% and yield from presumptive cases of 21.9%. Of active TB cases, 94% were new, 89% were pulmonary, 44% were bacteriologically-confirmed and 5% had HIV. Case notification rates per 100,000 in project townships increased from 142 during baseline (2011-2013) to 148 during intervention (2014-2016) periods. The yield from household and neigbourhood intervention was lower than community intervention. This finding highlights reconsidering the strategy of screening of contacts from historical index cases. Strategies to reach high-risk groups should be explored for future ACF interventions to increase yield of TB. Copyright © 2018 The Author(s). Published by Elsevier Ltd.. All rights reserved.

Transcutaneous electrical nerve stimulation (TENS) for pain management in labour

Science.gov (United States)

Dowswell, Therese; Bedwell, Carol; Lavender, Tina; Neilson, James P

2014-01-01

Background Transcutaneous nerve stimulation (TENS) has been proposed as a means of reducing pain in labour. The TENS unit emits low-voltage electrical impulses which vary in frequency and intensity. During labour, TENS electrodes are generally placed on the lower back, although TENS may be used to stimulate acupuncture points or other parts of the body. The physiological mechanisms whereby TENS relieves pain are uncertain. TENS machines are frequently operated by women, which may increase a sense of control in labour. Objectives To assess the effects of TENS on pain in labour. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (30 April 2011) and reference lists of retrieved papers. Selection criteria Randomised controlled trials comparing women receiving TENS for pain management in labour versus routine care, alternative non-pharmacological methods of pain relief, or placebo devices. We included all types of TENS machines. Data collection and analysis Two review authors assessed for inclusion all trials identified by the search strategy, carried out data extraction and assessed risk of bias. We have recorded reasons for excluding studies. Main results Seventeen trials with 1466 women contribute data to the review. Thirteen examined TENS applied to the back, two to acupuncture points, and two to the cranium. Overall, there was little difference in pain ratings between TENS and control groups, although women receiving TENS to acupuncture points were less likely to report severe pain (average risk ratio 0.41, 95% confidence interval 0.31 to 0.54; measured in two studies). The majority of women using TENS said they would be willing to use it again in a future labour. Where TENS was used as an adjunct to epidural analgesia there was no evidence that it reduced pain. There was no consistent evidence that TENS had any impact on interventions and outcomes in labour. There was little information on outcomes for mothers and babies. No

Brain MRI findings in two cases with eclampsia

Neurological complications in patients with eclampsia are varied and include headache, visual disturbances, focal neurological deficits, altered mental status and coma. Occasionally, a focal neurological deficit includes a variety of visual disturbances. The pathophysiology of CNS abnormalities in patients with eclampsia is uncertain. Our cases, combined with a review of the literature, demonstrate that there is no correlation among severity of hypertension, parity, and location of lesions at initial magnetic resonance (MR) imaging findings or between the severity of hypertension and neurological symptoms. Two typical patterns are seen on MR images of patients with eclampsia. Lesions in the region of the posterior cerebral circulation are most common and are frequently associated with visual disturbances. Although there are lesions in the deep white matter or basal ganglia, a focal neurological deficit or alterations in mental status may not develop. This demonstrates the sensitivity of MR imaging in the detection of abnormalities in patients with eclampsia, even those without neurological deficits. 13 refs., 1 tab., 2 figs

2017-09-14

Neuropathic pain, which is due to nerve disease or damage, represents a significant burden on people and society. It can be particularly unpleasant and achieving adequate symptom control can be difficult. Non-pharmacological methods of treatment are often employed by people with neuropathic pain and may include transcutaneous electrical nerve stimulation (TENS). This review supersedes one Cochrane Review 'Transcutaneous electrical nerve stimulation (TENS) for chronic pain' (Nnoaham 2014) and one withdrawn protocol 'Transcutaneous electrical nerve stimulation (TENS) for neuropathic pain in adults' (Claydon 2014). This review replaces the original protocol for neuropathic pain that was withdrawn. To determine the analgesic effectiveness of TENS versus placebo (sham) TENS, TENS versus usual care, TENS versus no treatment and TENS in addition to usual care versus usual care alone in the management of neuropathic pain in adults. We searched CENTRAL, MEDLINE, Embase, PsycINFO, AMED, CINAHL, Web of Science, PEDro, LILACS (up to September 2016) and various clinical trials registries. We also searched bibliographies of included studies for further relevant studies. We included randomised controlled trials where TENS was evaluated in the treatment of central or peripheral neuropathic pain. We included studies if they investigated the following: TENS versus placebo (sham) TENS, TENS versus usual care, TENS versus no treatment and TENS in addition to usual care versus usual care alone in the management of neuropathic pain in adults. Two review authors independently screened all database search results and identified papers requiring full-text assessment. Subsequently, two review authors independently applied inclusion/exclusion criteria to these studies. The same review authors then independently extracted data, assessed for risk of bias using the Cochrane standard tool and rated the quality of evidence using GRADE. We included 15 studies with 724 participants. We found a

Inflammatory pseudotumor, also known as inflammatory myofibroblastic tumor and plasma cell granuloma, is an uncommon low-grade lesion composed of spindle cells admixed with mature plasma cells and other inflammatory cells, such as histiocytes, lymphocytes, and eosinophils. Here, we describe the mammographic and ultrasonographic findings of a case of an inflammatory pseudotumor of the breast in a 60-year-old woman. With the suspicion of malignancy, core needle biopsy and surgical excision confirmed the mass as being an inflammatory pseudotumor of the breast.

To determine the radiologic characteristics of malignant tumors arising from ovarian endometriosis. The radiologic findings of eleven patients with pelvic masses histologically confirmed as malignant ovarian tumors arising from endometriosis were retrospectively reviewed. All patients underwent MR, and six underwent ultrasonography. The findings were evaluated with regard to tumor size and shape, locularity, thickness and enhancement of the wall and septa, the presence of papillary nodule or solid portion, signal intensity of the locule, the presence of mass in contralateral ovary, ascites, local invasion, distant metastases, and the Pathologic diagnosis included clear cell carcinoma in six cases, endometrioid carcinoma in three, and mucinous cystadenocarcinoma of borderline malignancy and endometrial stromal sarcoma in one case each. Tumor size ranged from 8 to 20 (mean, 12.7)cm. The tumors were mixed in four cases, entirely cystic in three, predominantly cystic in three, and predominantly solid in one. Six cases were unilocular and five were multilocular. The wall and septa varied in thickness and regularity and were well enhanced in all but one case. In all cases papillary nodules or solid portions with similar enhancement to uterine myometrium were seen. On T1WI, the signal intensity of fluid was seen to be high in eight cases, low or intermediate in two, and of differing intensity in one. Ten cases showed high signal intensity on T2WI, whereas in one case in which high signal intensity was seen on T1WI, there was low signal intensity(shading). In three cases the contralateral ovary contained an endometrioma. Other features included ascites in seven cases and peritoneal seeding in one. Malignant ovarian tumors arising from endometriosis showed radiologic features of malignancy:they were larger than 10cm, there was enhancement of the wall and septa, and a papillary nodule or solid portion was present. However, the presence of hyperintense fluid, as seen on T1WI

In 2012-2013, the English National Health Service mandated hospitals to conduct systematic case-finding of people with dementia among older people with unplanned admissions. The method was not defined. The aim of this study was to understand current approaches to dementia case-finding in acute hospitals in England and explore the views of healthcare professionals on perceived benefits and challenges. Qualitative study involving interviews, focus groups and thematic content analysis. Primary care and secondary care across six counties in the East of England. Hospital staff involved in dementia case-finding and primary care staff in the catchment areas of those hospitals. We recruited 23 hospital staff and 36 primary care staff, including 30 general practitioners (GPs). Analysis resulted in three themes: (1) lack of consistent approaches in case-finding processes, (2) barriers between primary care and secondary care which impact on case-finding outcomes and (3) perceptions of rationale, aims and impacts of case-finding. The study shows that there were variations in how well hospitals recorded and reported outcomes to GPs. Barriers between primary care and secondary care, including GPs' lack of access to hospital investigations and lack of clarity about roles and responsibilities, impacted case-finding outcomes. Staff in secondary care were more positive about the initiative than primary care staff, and there were conflicting priorities for primary care and secondary care regarding case-finding. The study suggests a more evidence-based approach was needed to justify approaches to dementia case-finding. Information communicated to primary care from hospitals needs to be comprehensive, appropriate and consistent before GPs can effectively plan further investigation, treatment or care. Follow-up in primary care further requires access to options for postdiagnostic support. There is a need to evaluate the outcomes for patients and the economic impact on health and care

2012-05-01

Clinical cases of hantavirus pulmonary syndrome (HPS) can be challenging to differentiate from other acute respiratory diseases, which can lead to delays in diagnosis, treatment, and disease reporting. Rapid onset of severe disease occurs, at times before diagnostic test results are available. This study's objective was to examine the clinical characteristics of patients that would indicate HPS to aid in detection and reporting. Test results of blood samples from U.S. patients suspected of having HPS submitted to the Centers for Disease Control and Prevention from 1998-2010 were reviewed. Patient information collected by case report forms was compared between HPS-confirmed and test-negative patients. Diagnostic sensitivity, specificity, predictive values, and likelihood ratios were calculated for individual clinical findings and combinations of variables. Of 567 patients included, 36% were HPS-confirmed. Thrombocytopenia, chest x-rays with suggestive signs, and receiving supplemental oxygenation were highly sensitive (>95%), while elevated hematocrit was highly specific (83%) in detecting HPS. Combinations that maximized sensitivity required the presence of thrombocytopenia. Using a national sample of suspect patients, we found that thrombocytopenia was a highly sensitive indicator of HPS and should be included in surveillance definitions for suspected HPS. Using a sensitive suspect case definition to identify potential HPS patients that are confirmed by highly specific diagnostic testing will ensure accurate reporting of this disease.

2001-10-01

Purpose: To describe the magnetic resonance (MR) appearance and associated clinical findings of partial distal biceps tendon tears. Design: Twenty elbow MR images at 1.5 T, performed over a 7 year period, were reviewed for an appearance of partial tears in the distal biceps. These images were assessed by two musculoskeletal radiologists for the extent of: (a) abnormal signal intensity within the tendon, and the presence of (b) bicipitoradial bursitis, and (c) bony microavulsive injury of the radial tuberosity. Medical records for nine of the 20 cases were reviewed for the clinical findings of ecchymosis, trauma, sensation of a ''pop'', loss of function, and acuity of onset. Results: Twenty partial distal biceps tendon tears were seen. All displayed an abnormally increased signal in the distal biceps tendon. Three of 20 (15%) showed a 25% to 50% tear, ten of 20 (50%) showed a 50% tear, and seven of 20 (35%) showed a 75% to 90% tear. Bicipitoradial bursitis was seen in 11 of 20 (55%) cases. Bony microavulsive injury of the radial tuberosity was observed in 10 of 20 (50%). Of the nine cases reviewed for associated clinical findings, surprisingly, only three (33%) experienced an acute traumatic episode with an abrupt onset of pain. An insidious onset was reported in four of nine (44%). Sensation of a ''pop'' was recorded in only two of nine (22%) cases. Ecchymosis and loss of function were not seen in any of the cases. Finally, surgical conformation was obtained for three cases. Conclusion: Partial distal biceps tendon tears have a characteristic MR appearance, demonstrate little functional deficit, and may be attritional in their etiology due to the observation of a low number of patients reporting trauma or an acute onset.

Full Text Available In the period from 1991 to 2001 there were four patients followed up who suffered from cystinuria and cystine calcinosis. The therapy consisting of the cystine dilution in the urine by a great taking-in of liquids and the urine alkalization was combined with alphamercaptopropione glycine and captoprile that bind cystine as well as a respective diet. Alphamercaptopropione glycine leads to the reduction of the already-formed calculus and their easier treatment in the case of a possible need for extracorporeal lithotripsy (ESWEL. During the ten-year follow-up of a small series of patients there were no complications related to the medicament treatment.

The reliability and validity of self-reported reproductive history and obstetric morbidity amongst birth to ten mothers in Soweto

Directory of Open Access Journals (Sweden)

GTH Ellison

2000-09-01

Full Text Available Objective: To assess whether self-reports of reproductive history and obstetric morbidity provide an accurate basis for clinical decision-making. Setting, participants and methods: Self-reports of maternal age and reproductive history, together with clinical measurements of five medical disorders, were abstracted from the obstetric notes of 517 mothers whose children were enrolled in the Birth to Ten study. These data were compared to self-reported information collected by interview during the Birth to Ten study. Findings: The reliability of self-reported age and gravidity was high (R=0.810-0.993, yet self-reports of previous miscarriages, terminations, premature- and stillbirths were only fairly reliable (Kappa=0.48-0.50. Self-reported diabetes and high blood pressure had specificities of more than 95% for glycosuria, hypertension and pre-eclampsia. However, the specificity of self-reported oedema for hypertensive disorders and the specificity of self-reported urinary tract infection for STD seropositivity were only around 65%. Conclusions: The modest reliability and limited validity of self-reported obstetric morbidity undermines the clinical utility of this information. Recommendations: These results strengthen the case for providing mothers with “Home-based Maternal Records” to facilitate access to accurate obstetric information during subsequent clinical consultations.

Subacute combined degeneration (SCD) of the spinal cord is a neurological complication arising from vitamin B 12 deficiency. Typical findings are demyelination and axonal loss of the posterior and lateral columns of the thoracic and cervical spinal cord, leading to sensory ataxia and paresthesia. Clinical and neurological features and MRI findings all contribute to the diagnosis of this entity. In the Korean medical literature, only one case of of SCD involving pre-treatment MRI has been reported. We describe one case of SCD in a post-gastrectomy patient who initially presented with progressive sensory abnormality in both upper and lower extremities and showed T2 hyperintensity in the posterior and lateral columns of the spinal cord; this diminished, with clinical improvement, after vitamin B12 therapy. Our report includes the MR images obtained during follow up. (author)

Transcutaneous electric nerve stimulation (TENS) is a non-pharmacological method which is widely used by medical and paramedical professionals for the management of acute and chronic pain in a variety of conditions. Similarly, it can be utilized for the management of pain during various dental procedures as well as pain due to various conditions affecting maxillofacial region. This review aims to provide an insight into clinical research evidence available for the analgesic and non analgesic uses of TENS in pediatric as well as adult patients related to the field of dentistry. Also, an attempt is made to briefly discuss history of therapeutic electricity, mechanism of action of TENS, components of TENs equipment, types, techniques of administration, advantages and contradictions of TENS. With this we hope to raise awareness among dental fraternity regarding its dental applications thereby increasing its use in dentistry. Key words:Dentistry, pain, TENS.

To analyse and compare high-resolution CT findings of pulmonary tuberculosis with consolidation and mycoplasma pneumonia. Twenty patients with pulmonary tuberculosis [confirmed by sputum culture (n=9) and bronchoscopic biopsy (n=11)] and airspace consolidation on high-resolution CT and 17 patients with mycoplasma pneumonia, confirmed by serologic test, were included in this study. High-resolution CT findings were analyzed in terms of ground-glass opacities, distribution of consolidation, type of nodules, cavities, interlobular septal thickening, bronchial dilatations, bronchial wall thickening and pleural effusion. In patients with tuberculosis, average age was 33.5 years (range, 20-67); in those with mycoplasma pneumonia it was 32.5 years (range, 17-74). Segmental and subsegmental distributions were most common in both diseases; the preferred site of consolidation was different, however; for tuberculosis it was the upper lobes (13 cases, 65%; bilateral involvement, 7 cases); for mycoplasma pneumonia it was the lower lobes (11 cases, 64.7%). Non-segmental (diffuse and random) distribution of ground-glass opacities were seen in two patients(11.8%) with mycoplasma pneumonia. Centrilobular nodules, branching linear opacities and alveolar nodules were not different in both diseases, but there were nodules above 10mm in 14 cases of tuberculosis and in only one case of mycoplasma pneumonia. Tree-in-bud appearances were seen in five cases of tuberculosis. Cavities without air-fluid level were noted in ten cases of tuberculosis. Other interlobular septal thickening, bronchial wall thickening, bronchial dilatation and pleural effusion were not different in both diseases. There was considerable overlap between high resolution CT findings of tuberculosis with airspace consolidation and those of mycoplasma pneumonia. The location of consolidation, type of nodules, and the presence of tree-in-bud appearance and cavities help in the differentiation of the two diseases, however.

Objective: The purpose of this work was to analysis the most suggestive imaging findings of Castleman disease in the abdomen and pelvis and to improve the recognition of this rare disease. Methods: Ten patients with pathologically proved Castleman disease in the abdomen (n=9) and pelvis (n=1) were included in this study. Patients were 18-56 yeas old (mean=40); 7 were men and 3 women. Imaging findings (CT and MRI, n=4; only CT, n=4; only MRI, n=2) were retrospectively reviewed and correlated with clinical and pathologic findings. Results: The lesions were divided into localized (n=9) and disseminated (n=1) group. The pathologic subtypes of all 9 cases of localized disease were hyaline vascular type. Imaging findings showed a single large mass in six and a single dominant mass with small satellite nodules in three. On plain CT images, the lesions manifested as homogeneous soft masses, which is isoattenuating to muscle. After intravenous injection of contrast media, most of the masses enhanced sharply (5/7) with the attenuation similar to large arteries at arterial phase and delay scans. On MR imaging, the lesions also were homogenous and had isointense or slightly low signal intensity compared with that of muscle on T 1 weighted images and high signal intensity on T 2 weighted images, and showed contrast enhancement in a similar pattern to contrast enhanced CT. After intravenous injection of contrast media, areas of central lower radial attenuation in the mass were noted in 4 cases of large masses ( > 5 cm) and proved to be fibrotic component pathologically. The pathologic subtypes of 1 cases of disseminated disease was plasma cell type. Imaging findings showed several well-defined nodules lied in the retroperitoneal zone that enhanced sharply with the attenuation similar to large arteries after intravenous injection of contrast media. Conclusion: Imaging findings of Castleman disease in the abdomen and pelvis are closely associated with its pathology. The most

In 14 cases of normal and abnormal thymus proved surgically and histopathologically in korea University Hae Wha Hospital during recent 6 years, the clinical and CT findings were analyzed. 1. Of 14 cases, 2 cases were normal thymus, 5 cases were thymic hyperplasia, 4 cases were benign thymoma, 2 case were malignant thymoma and 1 case was thymic cyst. 2. Of 14 cases, 10 cases were associated with myasthenia gravis, and 7 of these 10 cases were 3rd to 5th decades females. Among 10 cases with myasthenia gravis. 5 cases were thymic hyperplasia, 1 case was benign thymoma, 2 cases were malignant thymoma, and 2 cases were normal thymus. 3. All 5 thymic hyperplasia were associated with myasthenia gravis. CT findings of thymic hyperplasia were normal in 4 cases and increased lobe thickness in 1 case. 4. Of 4 cases of benign thymoma, only 1 case was associated with myasthenia gravis, and all 4 cases were positive findings in CT scan. CT findings of benign thymoma were round or oval soft tissue mass in anterior mediastinum, and 1 case had punctuate calcifications. 5. Of 2 cases of malignant thymoma, all 2 cases were associated with myasthenia gravis and positive findings in CT scan. CT findings of malignant thymoma were anterior mediastinal soft tissue mass with obliteration of the normal fat planes surrounding great vessels. SVC compression, and pleural tumor implants. 6. CT yielded significant diagnostic information of differential diagnosis between thymoma and thymoma hyperplasia in myasthenia gravis patients. Also CT was highly sensitive test in detection of thymoma and determined the extent and invasiveness of thymoma.

1984-01-01

CT scans of a 59-year-old woman, with serologically comfirmed herpes simplex encephalitis (HSE) were studied sequentially from 9 days after onset. The initial findings in CT scan were low density areas in insular cortex, claustrum and hippocampus. The low density areas, then, spread to the temporal lobe, rectal and cingulate gyri and occipital lobe, according to clinical progression of the disease. However, these low density areas disappeared and changed into isodensity areas in 25-35 days after oneset, which then returned to low density areas again in 51 days after onset. Thes characteristic phenomenon resembled a ''fogging effect,'' which is frequently seen during the second or third week after onset of ischemic cerebral infarction. HSE is characterized pathologically by acute hemorrhagic necrotizing encephalitis. Though cerebral angiography was not performed in this case, these characteristic CT findings suggested that HSE may have been associated with vascular involvement. (author)

We here report each one case with primary aldosteronism (male, 28 years old) and Cushing syndrome (female, 37 years old). Both of the cases showed characteristic clinical signs of hypertension and typical laboratory findings of adreno-hormonal assays. In performance of whole body computed tomography, clear pictures of tumorous adenomas in both cases were taken and the sizes of adenomas in picture were completely same as the masses obtained by the lateral adrenectomies. As a result, the whole body computed tomography is very useful to diagnose the diseases of adrenal adenoma and hyperplasia. (author)

Imaging findings of pulmonary Langerhans cell histiocytosis (PLCH) demonstrate evolving changes over time, and the radiological transitions shown by imaging tools may allow a prediction of histopathological activity in PLCH. However, there are no reports describing how rapidly CT findings change with time. We describe a case of PLCH that showed a rapid evolutional change of the pulmonary lesions in a 48-year-old man, in which the nodular lesions showed cystic changes within two-month follow-up periods on chest CT scans

Objective: Although it is a rare condition, pigmented villonodular synovitis (PVNS) may involve temporomandibular joint (TMJ). The purpose of this study was to describe magnetic resonance (MR) findings of PVNS of the TMJ. Methods and material: Between April 1992 and August 2000, four patients (two men and two women, 22-58-year-old) who had histologically proven diagnoses of PVNS in their TMJ were found in our institution. Their MR findings were reviewed retrospectively, and were correlated with pathologic findings. Results: In all four patients, MR images invariably showed profound hypointensity on both T1- and T2-weighted sequences. This finding was seen diffusely and homogeneously throughout the lesion, and was considered to be due to paramagnetic effect attributed to heavy hemosiderin pigmentation, which was revealed by histopathological examination. MR images also showed aggressive nature of the lesions with adjacent skull base destruction and intracranial extension in two of them. Conclusion: As is the case in the other anatomic site, PVNS of the TMJ can be confidently diagnosed on MR imaging on the basis of the presence of hemosiderin. MR imaging also plays a pivotal role in surgical planning by precise and detailed localization of the lesion.

The elastofibroma dorse is a benign, nonencapsulated pseudotumor consisting of a proliferation of fibrous tissue and elastic fibers accompanied by fatty tissue. It is usually locate in the scapular region and can be unilateral or bilateral. The computed tomography and magnetic resonance findings are characteristic and, in the proper clinical context, practically pathognomonic: a fat-containing subcapsular mass with an attenuation coefficient and signal intensity similar to those of the adjacent muscles. We report two new cases of elastofibroma dorsi that fulfilled all the clinical and radiologic criteria, enabling the preoperative diagnosis. (Author) 15 refs

Effects of tripolar TENS on slow and fast motoneurons: a preliminary study using H-reflex recovery curve method.

Science.gov (United States)

Simorgh, L; Torkaman, G; Firoozabadi, S M

2008-01-01

This study aimed at examining the effect of tripolar TENS of vertebral column on the activity of slow and fast motoneurons on 10 healthy non-athlete women aged 22.7 +/- 2.21 yrs. H-reflex recovery curve of soleus (slow) and gastrocnemius (fast) muscles were recorded before and after applying tripolar TENS. For recording of this curve, rectangular paired stimuli were applied on tibial nerve (with 40-520 ISI, frequency of 0.2 Hz and pulse width of 600 micros). Our findings showed that maximum H-reflex recovery in gastrocnemius muscle appeared in the shorter ISI, while in soleus muscle, it appeared in the longer ISI and its amplitude slightly decreased after applying tripolar TENS. It is suggested that tripolar TENS excites not only the skin but also Ia and Ib afferents in the dorsal column. A Synaptic interaction of these afferents in spinal cord causes the inhibition of type I MNs and facilitation of type II MNs. This effect can be used in muscle tone modulation.

Methods: A cross-sectional analysis of household contacts living with an index TB case and FDR contacts living outside of households in Kampala, Uganda, is presented. Results: A total of 177 contacts (52 FDRs and 125 index household contacts of 31 TB cases were examined. Compared with index household contacts, FDR contacts were older, more likely to be TB symptomatic (50% vs 33%, had a higher percentage of abnormal chest X-rays (19% vs 11%, sputum smear positive (15% vs 5%, and many similar epidemiologic risk factors, including HIV infection (13% vs 10%. Contact groups had similar pulmonary tuberculosis prevalence: 9.6% in FDR vs 10.4% in index household contacts and similar Mycobacterium tuberculosis infection: 62% in FDR vs 61% in index households. Conclusion: TB is common among FDR contacts. High TB prevalence justifies targeting FDRs during household contact investigations. Combining TB active-case finding among FDR contacts with household contact investigation in low-income setting is feasible. This should be part of national TB control program strategies for increasing TB case-detection rates and reducing community TB transmission and death.

Malignant transformation is a rare and late complication of untreated chronic osteomyelitis. Known radiographic findings of the malignant transformation of chronic osteomyelitis are osteolytic or mixed sclerotic and osteolytic lesions with or without soft tissue mass. But its magnetic resonance (MR) imaging findings are rarely described in the literature. We experienced a case of an 82-year-old man diagnosed with squamous cell carcinoma arising from long standing chronic osteomyelitis of the tibia. Our case indicates that radiologists should consider the possibility of malignant transformation in patients with untreated chronic osteomyelitis, with enhancing soft tissue mass invading and extending through underlying bone cortex and medulla on MR imaging.

2006-01-01

How did the universe begin? Where do galaxies come from? How do stars and planets form? Where do the material particles we are made of come from? How did life begin? Today we have only provisional answers to such questions. But scientific progress will improve these answers dramatically over the next ten years, predicts John Gribbin in this riveting book. He focuses on what we know—or think we know—about ten controversial, unanswered issues in the physical sciences and explains how current cutting-edge research may yield solutions in the very near future. With his trademark facility for engaging readers with or without a scientific background, the author explores ideas concerning the creation of the universe, the possibility of other forms of life, and the fate of the expanding cosmos. He examines “theories of everything,” including grand unified theories and string theory, and he discusses the Big Bang theory, the origin of structure and patterns of matter in the galaxies, and dark mass and dark ene...

To report spectral domain optical coherence tomography findings in a case of typical tamoxifen retinopathy. In this observational case report, a patient with tamoxifen retinopathy was imaged with spectral domain optical coherence tomography and fundus auto fluorescence. Spectral domain optical coherence tomography showed numerous hyperreflective spots within the retina, mainly in the inner retinal layers in both the eyes. The external limiting membrane, the Inner Segment-Outer Segment junction, and the photoreceptors were not discernable at the fovea in the right eye. In the left eye, there was foveal atrophy with total loss of photoreceptors. The autofluorescent images showed macular hypofluorescence with foveal hyperfluorescence. Spectral domain optical coherence tomography demonstrated abnormalities in the outer retinal layers in tamoxifen retinopathy. There were also characteristic alterations in the autofluorescence pattern at the macula in tamoxifen retinopathy.

Unilateral pulmonary artery hypoplasia or agenesis without congenital cardiovascular anomalies is rare in adults. We report a case of a 36-year-old man with isolated left unilateral pulmonary artery hypoplasia with recurrent hemoptysis. On computed tomography (CT), the left pulmonary artery showed hypoplasia with multiple collateral vessels seen in the mediastinum and the left hemithorax. Also, parenchymal bands and peripheral linear opacities were seen in the affected lung, which were probably due to chronic infarction induced by unilateral pulmonary artery hypoplasia. There are only a few reports focusing on the radiologic findings in the pulmonary parenchyma induced by unilateral pulmonary artery hypoplasia, such as parenchymal bands and peripheral linear opacities. Therefore we report this case, which focused on the CT findings in the pulmonary parenchyma due to isolated unilateral pulmonary artery hypoplasia.

The presentation herewith as scripted is to describe a case with Nevus sebaceous with oral manifestations. Nevus Sebaceous or Jadassohn's nevus is an epidermal nevus with predominant sebaceous glands seen histologically. Reports of oral involvement have been few ranging from papillomatous growths of the tongue, gingiva, palate to dental abnormalities such as anodontia and dysodontia. The present case describes a nevus sebaceous present on the right half of the face and neck, showing intraoral papillomatous growth on the lateral part of the tongue on the right side. The patient was healthy and did not report involvement of any other organ systems. Intraoral involvement may be seen in patients with Nevus Sebaceous, hence proper screening is important. In patients presenting with large nevi on the head and neck such as ours, involvement of other systems such as ocular, neurologic and oral lesions may be seen, therefore screening of such patients is of importance. Patients with nevus sebaceous may be predisposed to the occurrence of tumours. Therefore, careful screening of such patients is necessary.

Undifferentiated pleomorphic sarcoma (UPS), previously known as malignant fibrous histiocytoma, is a soft tissue sarcoma arising from mesenchymal tissue of the body. UPS of the gastrointestinal tract is known to be rare and only a few cases have been reported in the literature. Based on our case and review of the other relevant literature, the CT findings of primary UPS of the small bowel included nodular bowel wall thickening with homogeneous enhancement. It presents as a rapidly growing tumor without bowel obstruction, and it may be accompanied by distant metastasis.

Myositis ossificans (MO) is a benign soft tissue lesion with non-neoplastic heterotopic bone formation. MO in the intermediate and mature stages can be easily diagnosed if characteristic imaging findings such as a peripheral zonal pattern of ossification with variable thickness is observed. However, it is difficult to correctly diagnose early MO because it can mimic malignancy clinically, radiologically, and histopathologically. We report a case of early pseudosarcomatous phase of non-traumatic MO with atypical imaging findings. A 59-year-old woman presented with pain followed by a mass in the left thigh within a week. MR imaging and ultrasonography showed an intramuscular lesion with preserved muscle fascicles in the vastus lateralis muscle. Intralesional ossification or calcification was not seen on ultrasonography. A diagnosis of myositis ossificans was made by ultrasonographically guided biopsy. (orig.)

Full Text Available Osteoid osteoma is a small, benign osteoblastic tumor consisting of a highly vascularized nidus of connective tissue surrounded by sclerotic bone. Three-quarters of osteoid osteomas are located in the long bones, and only 7-12% in the vertebral column. The classical clinical presentation of spinal osteoid osteoma is that of painful scoliosis. Other clinical features include nerve root irritation and night pain. Osteoid osteoma has characteristic computed tomography (CT findings. Because magnetic resonance imaging (MRI findings of the osteoid osteomas causing intense perinidal edema can be confusing, these patients should be evaluated with clinical findings and other imaging techniques. In this study, we present X-ray, CT, and MRI findings of a case with osteoid osteoma located in thoracic 1 vertebra left lamina and transverse process junction leading to brachial neuralgia symptoms.

Two cases of unilateral posterior scleritis, seen in 56-year-old and 68-year-old females, are reported. Computerized tomography showed characteristic findings, as follows: 1) Thickening of the posterior sclera and surrounding tissue. 2) Irregularity of the posterior wall of the eyeball. 3) Increased radiographic density in the posterior wall of the eyeball. Ultrasonography also suggested thickening of the posterior sclera. Computerized tomography and ultrasonography are considered useful in the diagnosis of posterior scleritis. (author)

The authors report a case of a 4-year-old girl patient complaining of leukokoria on the right eye 15 days ago. The ophthalmologic exam was not possible to do because of catarata. So, a magnetic resonance imaging (MRI) examination was performed, which revealed hyperintense vitreous camera and enhancing intraocular mass. Diagnosis of ocular toxocariasis was based on MRI findings and laboratorial examinations. The corticoids treatment was performed and the child had a good evolution. (author)

Purpose: Enucleation after stereotactic radiotherapy (SRT) for juxtapapillary choroidal melanoma may be required because of tumor progression (TP) or the development of intractable radiation-induced neovascular glaucoma (NVG). We compare pathologic changes and dosimetric findings in those eyes enucleated secondary to NVG as opposed to TP to better understand potential mechanisms. Methods and Materials: Patients with juxtapapillary choroidal melanoma treated with SRT (70 Gy in 5 fractions, alternate days over a total of 10 days) at the Princess Margaret Hospital, Toronto, Ontario, Canada, who underwent enucleation between 1998 and 2006 were selected. We correlated dosimetric data based on the patient's original SRT treatment plan with histopathologic findings in the retina, optic nerve head, and anterior chamber. A dedicated ocular pathologist reviewed each case in a blinded fashion. Results: Ten eyes in ten patients were enucleated after SRT. Six were enucleated secondary to NVG and four secondary to because of TP. Aggressive tumor features such as invasion of the sclera and epithelioid cell type were observed predominantly in the TP group. Retinal damage was more predominant in the NVG group, as were findings of radiation-related retinal vascular changes of fibrinoid necrosis and hyalinization. No conclusive radiation-related effects were found in the anterior chamber. The maximum point dose and dose to 0.1 cc were lower for the anterior chamber as compared with the dose to the tumor, retina, and optic nerve head. The mean 0.1-cc doses to the retina were 69.4 Gy and 73.5 Gy and to the anterior chamber were 4.9 Gy and 17.3 Gy for the NVG group and tumor progression group, respectively. Conclusions: Our findings suggest that NVG is due to radiation damage to the posterior chamber of the eye rather than primary radiation damage to the anterior segment.

Illicit drug use and homelessness are major contributors to the incidence of tuberculosis (TB) among inhabitants of major cities. The primary objective of this study was to establish a sustainable low-threshold chest X-ray screening programme for pulmonary TB among illicit drug users and homeless persons and to integrate this into the existing public health programme for active case finding. A secondary objective was to estimate the coverage of the programme, assess other risk factors and determine TB rates and treatment outcome in these two groups. Illicit drug users and homeless persons were asked to voluntarily participate in an X-ray screening programme. The coverage of the intervention, total number and characteristics of cases and the follow-up of treatment were assessed. A total of 4,529 chest radiographs were made from 3,477 persons, of whom 66% were homeless and 34% were illicit drug users, between May 2002 and April 2007. Coverage for screening once every 2 years ranged between 18 and 26%. Thirty-nine TB cases (14 drug users, 25 homeless persons) were identified, representing 8.7% of the total case load of 448 notified cases of pulmonary TB in Frankfurt during this period. Among the drug users, human immunodeficiency virus coinfection (10/14) seemed to play a key role in the development of TB. The case-finding rate of 861/100,000 radiographs (1,122/100,000 persons) is as high as that in routine contact investigations (1,078/100,000). Among all individuals with TB, 76% completed treatment. A novel targeted TB screening approach with voluntary radiographic examination of illicit drug users and homeless persons can be integrated into the existing public TB prevention programme and provides a high case-finding rate.

Cianci, F

2012-04-01

We present our experience in the management of choledochal cysts from 1999 to 2009. A retrospective review of all charts with a diagnosis of choledochal cysts in our institution in this ten-year period. Data was collated using Excel. A total of 17 patients were diagnosed with choledochal cyst: 9 females and 8 males. The average age at diagnosis was 28 months (range from 0 to 9 years). The most common presenting symptoms were obstructive jaundice 6 (35%) and abdominal pain and vomiting 4 (23%). Ultrasound (US) was the initial diagnostic test in all cases with 4 patients requiring further investigations. All patients underwent Roux-en-Y Hepaticojejunostomy. The average length of stay was 11 days. Patients were followed up with Liver Function Tests (LFTS) and US 4-6 weeks post-operatively. Three patients developed complications including post-op collection, high drain output requiring blood transfusion and adhesive bowel obstruction. Our overall experience with choledochal cyst patients has been a positive one with effective management and low complication rates.

Full Text Available The TATE trial was a multicentre pragmatic randomized controlled trial of supplementing primary care management (PCM-consisting of a GP consultation followed by information and advice on exercises-with transcutaneous electrical nerve stimulation (TENS, to reduce pain intensity in patients with tennis elbow. This paper reports the health economic evaluation.Adults with new diagnosis of tennis elbow were recruited from 38 general practices in the UK, and randomly allocated to PCM (n = 120 or PCM plus TENS (n = 121. Outcomes included reduction in pain intensity and quality-adjusted-life-years (QALYs based on the EQ5D and SF6D. Two economic perspectives were evaluated: (i healthcare-inclusive of NHS and private health costs for the tennis elbow; (ii societal-healthcare costs plus productivity losses through work absenteeism. Mean outcome and cost differences between the groups were evaluated using a multiple imputed dataset as the base case evaluation, with uncertainty represented in cost-effectiveness planes and through probabilistic cost-effectiveness acceptability curves. Incremental healthcare cost was £33 (95%CI -40, 106 and societal cost £65 (95%CI -307, 176 for PCM plus TENS. Mean differences in outcome were: 0.11 (95%CI -0.13, 0.35 for change in pain (0-10 pain scale; -0.015 (95%CI -0.058, 0.029 for QALYEQ5D; 0.007 (95%CI -0.022, 0.035 for QALYSF6D (higher score differences denote greater benefit for PCM plus TENS. The ICER (incremental cost effectiveness ratio for the main evaluation of mean difference in societal cost (£ relative to mean difference in pain outcome was -582 (95%CI -8666, 8113. However, incremental ICERs show differences in cost-effectiveness of additional TENS, according to the outcome being evaluated.Our findings do not provide evidence for or against the cost-effectiveness of TENS as an adjunct to primary care management of tennis elbow.

We present a case of a child with MELAS syndrome (mitochondrial encephalo-myopathy with lactic acidosis and stroke-like episodes), discussing clinical manifestation, ocular findings and diagnostic challenges. Predominant ocular symptom was a transient complete visual loss, while the predominant ocular sign was a visual field defect. The diagnosia was based on clinical manifestation, laboratory tests, brain scans and genetic testing which confirmed the pathognomonic mutation in the MTTL1 gene encoding the mitochondrial tRNA for leucine 3243> G. Ocular examination demonstrated decreased visual acuity (with bilateral best corrected visual acuity of .1). Periodical, transient visual loss and visual field defects were clinically predominant. Specialist investigations were carried out, which demonstrated homonymous hemianopia (kinetic perimetry), bilateral partial optic nerve atrophy (RetCam). Funduscopy and electrophysiology mfERG study did not confirm features of retinitis pigmentosa. The brain scans revealed numerous small cortical ischemic lesions within the frontal, parietal and temporal lobes, post-stroke focal areas within the occipital lobes and diffuse calcifications of the basal ganglia. During several years of follow-up, visual field defects showed progressive concentric narrowing. The patient received a long-term treatment with arginine, coenzyme Q and vitamin D, both oral and intravenous, but no beneficial effect for the improvement of ophthalmic condition was observed. As it is the case in severe MELAS syndrome, the course of disease was fatal and the patientdied at the age of 14.

Despite the progress made in the past decade, tuberculosis (TB) control still faces significant challenges. In many countries with declining TB incidence, the disease tends to concentrate in vulnerable populations that often have limited access to health care. In light of the limitations of the current case-finding approach and the global urgency to improve case detection, active case-finding (ACF) has been suggested as an important complementary strategy to accelerate tuberculosis control especially among high-risk populations. The present exercise aims to develop a model that can be used for county-level project planning. A simple deterministic model was developed to calculate the number of estimated TB cases diagnosed and the associated costs of diagnosis. The model was designed to compare cost-effectiveness parameters, such as the cost per case detected, for different diagnostic algorithms when they are applied to different risk populations. The model was transformed into a web-based tool that can support national TB programmes and civil society partners in designing ACF activities. According to the model output, tuberculosis active case-finding can be a costly endeavor, depending on the target population and the diagnostic strategy. The analysis suggests the following: (1) Active case-finding activities are cost-effective only if the tuberculosis prevalence among the target population is high. (2) Extensive diagnostic methods (e.g. X-ray screening for the entire group, use of sputum culture or molecular diagnostics) can be applied only to very high-risk groups such as TB contacts, prisoners or people living with human immunodeficiency virus (HIV) infection. (3) Basic diagnostic approaches such as TB symptom screening are always applicable although the diagnostic yield is very limited. The cost-effectiveness parameter was sensitive to local diagnostic costs and the tuberculosis prevalence of target populations. The prioritization of appropriate target

In 80 cases of focal epilepsy, excluding such cases as late onset after the age of 30 and traumatic or expansive lesions, the epileptogenic foci have been studied by comparing the CT findings with the seizure types and the EEG findings. The results were as follows: (1) Abnormal CT findings were observed in 36% of the patients. (2) These findings were classified into 4 large groups: localized cerebral atrophy, localized low density, localized high density with contrast enhancement and diffuse cerebral atrophy. (3) The incidence of CT abnormality was higher in the cases with continuous and localized EEG abnormality than in the cases with other types of EEG abnormality. In 48% of the cases, the location of the abnormal CT findings coincided with their EEG foci. (4) In the cases of temporal lobe epilepsy without abnormal CT images, the print-out data compared with the bilateral promised temporal regions, before and after contrast enhancement. The EMI-No. of the medial temporal focus increased more than that of the contralateral side in 3 cases out of 4 after contrast-media injection. (5) Moreover, for the purpose of comparing the CT findings on general seizures with those in focal seizures, we have studied 80 cases of general seizures. In the cases of the general seizures, abnormal CT findings were observed in only 16%. These abnormal findings were diffuse in 5 cases, localized in 6 cases, and combined in 3 cases. (author)

The purpose of this study was to evaluate the mammographic and sonographic findings of pure sclerosing adenosis. We retrospectively reviewed the mammographic and sonographic findings in 40 cases of pure sclerosing adenosis confirmed by core needle biopsy (n = 23), vacuum-assisted biopsy (n = 7), excision biopsy (n = 9), and lumpectomy (n = 1) from January 2002 to March 2010. All imaging findings were analyzed according to the American College of Radiology (ACR) breast imaging reporting and data system (BI-RADS). Radiologic features were correlated with pathologic findings. Although most mammograms showed negative findings (57%), calcification was the most common abnormal finding of sclerosing adenosis. On sonography, the most common finding was a circumscribed oval hypoechoic mass without posterior features (78%). Most masses showed BI-RADS category 3, (75%, 27/36). Five cases showed categories 4 or 5 (14%, 5/36). Most mammographic and sonographic findings of sclerosing adenosis are non-specific and non-pathognomonic, even though sometimes sclerosing adenosis can be radiologically or histopathologically confused with malignancy

It is estimated that the standard, passive case finding (PCF) strategy for detecting cases of tuberculosis (TB) in Myanmar has not been successful: 26% of cases are missing. Therefore, alternative strategies, such as active case finding (ACF) by community volunteers, have been initiated since 2011. This study aimed to assess the contribution of a Community Based TB Care Programme (CBTC) by local non-government organizations (NGOs) to TB case finding in Myanmar over 4 years. This was a descriptive study using routine, monitoring data. Original data from the NGOs were sent to a central registry within the National TB Programme and data for this study were extracted from that database. Data from all 84 project townships in five regions and three states in Myanmar were used. The project was launched in 2011. Over time, the number of presumptive TB cases that were referred decreased, except in the Yangon Region, although in some areas, the numbers fluctuated. At the same time, there was a trend for the proportion of cases treated, compared to those referred, that decreased over time (P = 0.051). Overall, among 84 townships, the contribution of CBTC to total case detection deceased from 6% to 4% over time (P < 0.001). Contrary to expectations and evidence from previous studies in other countries, a concerning reduction in TB case finding by local NGO volunteer networks in several areas in Myanmar was recorded over 4 years. This suggests that measures to support the volunteer network and improve its performance are needed. They may include discussion with local NGOs human resources personnel, incentives for the volunteers, closer supervision of volunteers and improved monitoring and evaluation tools.

Risk factors for inadequate TB case finding in Rural Western Kenya: a comparison of actively and passively identified TB patients.

Directory of Open Access Journals (Sweden)

Anna H Van't Hoog

Full Text Available The findings of a prevalence survey conducted in western Kenya, in a population with 14.9% HIV prevalence suggested inadequate case finding. We found a high burden of infectious and largely undiagnosed pulmonary tuberculosis (PTB, that a quarter of the prevalent cases had not yet sought care, and a low case detection rate.We aimed to identify factors associated with inadequate case finding among adults with PTB in this population by comparing characteristics of 194 PTB patients diagnosed in a health facility after self-report, i.e., through passive case detection, with 88 patients identified through active case detection during the prevalence survey. We examined associations between method of case detection and patient characteristics, including HIV-status, socio-demographic variables and disease severity in univariable and multivariable logistic regression analyses.HIV-infection was associated with faster passive case detection in univariable analysis (crude OR 3.5, 95% confidence interval (CI 2.0-5.9, but in multivariable logistic regression this was largely explained by the presence of cough, illness and clinically diagnosed smear-negative TB (adjusted OR (aOR HIV 1.8, 95% CI 0.85-3.7. Among the HIV-uninfected passive case detection was less successful in older patients aOR 0.76, 95%CI 0.60-0.97 per 10 years increase, and women (aOR 0.27, 95%CI 0.10-0.73. Reported current or past alcohol use reduced passive case detection in both groups (0.42, 95% CI 0.23-0.79. Among smear-positive patients median durations of cough were 4.0 and 6.9 months in HIV-infected and uninfected patients, respectively.HIV-uninfected patients with infectious TB who were older, female, relatively less ill, or had a cough of a shorter duration were less likely found through passive case detection. In addition to intensified case finding in HIV-infected persons, increasing the suspicion of TB among HIV-uninfected women and the elderly are needed to improve TB case

Supersymmetric gauged scale covariance in ten and lower dimensions

We present globally supersymmetric models of gauged scale covariance in ten, six, and four dimensions. This is an application of a recent similar gauging in three dimensions for a massive self-dual vector multiplet. In ten dimensions, we couple a single vector multiplet to another vector multiplet, where the latter gauges the scale covariance of the former. Due to scale covariance, the system does not have a Lagrangian formulation, but has only a set of field equations, like Type IIB supergravity in ten dimensions. As by-products, we construct similar models in six dimensions with N=(2,0) supersymmetry, and four dimensions with N=1 supersymmetry. We finally get a similar model with N=4 supersymmetry in four dimensions with consistent interactions that have never been known before. We expect a series of descendant theories in dimensions lower than ten by dimensional reductions. This result also indicates that similar mechanisms will work for other vector and scalar multiplets in space-time lower than ten dimensions

Healthcare Worker Preferences for Active Tuberculosis Case Finding Programs in South Africa: A Best-Worst Scaling Choice Experiment.

Directory of Open Access Journals (Sweden)

Nathan N O'Hara

Full Text Available Healthcare workers (HCWs in South Africa are at a high risk of developing active tuberculosis (TB due to their occupational exposures. This study aimed to systematically quantify and compare the preferred attributes of an active TB case finding program for HCWs in South Africa.A Best-Worst Scaling choice experiment estimated HCW's preferences using a random-effects conditional logit model. Latent class analysis (LCA was used to explore heterogeneity in preferences."No cost", "the assurance of confidentiality", "no wait" and testing at the occupational health unit at one's hospital were the most preferred attributes. LCA identified a four class model with consistent differences in preference strength. Sex, occupation, and the time since a previous TB test were statistically significant predictors of class membership.The findings support the strengthening of occupational health units in South Africa to offer free and confidential active TB case finding programs for HCWs with minimal wait times. There is considerable variation in active TB case finding preferences amongst HCWs of different gender, occupation, and testing history. Attention to heterogeneity in preferences should optimize screening utilization of target HCW populations.

Erythema multiforme (EM), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are cutaneous hypersensitivityreactions that develop in response to specific triggers such as medications and certain infections. Vaccines, which undergo rigorous safety testing prior to use in humans, are a rare cause of SJS/TEN and little is known about the frequency of such events and corresponding pathogenesis. Herein, we discuss a case of suspected TEN in a 19-year-old woman who received the meningococcal B vaccine (the first report of such an association) and conduct a systematic review of the associated literature. We also discuss management of this patient with a single dose of etanercept. Relevant literature was searched using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. A total of 29 articles reporting EM, SJS, or TEN following vaccination were included from >5 countries. Of the 29, 22 articles reported EM, 6/29 reported SJS, and 4/29 reported TEN (3 articlesreported cases of both EM and SJS/TEN). We suggest consideration of vaccines as an etiology for cases of SJS or TEN that begin with an EM-like presentation, and provide further evidence for the use of etanercept as a viable treatment for TEN.

To evaluate the brain MRI findings in patients with neuropsychiatric lupus. In 26 patients (M:F = 2:24 ; aged 9-48 years) in whom the presence of systemic lupus erythematosus was clinically or pathologically proven and in whom neuropsychiatric lupus was also clinically diagnosed, the findings of brain MRI were retrospectively evaluated. MR images were analyzed with regard to the distribution, location, size and number of lesions due to cerebral ischemia or infarction, the presence of cerebral atrophy, and the extent and degree of brain parenchymal and intravascular enhancement. The most common MRI findings were lesions due to cerebral ischemia or infarction occurring in 18 patients (69%), and located within deep periventricular white matter (n=10), subcortical white matter (n=8), the cerebral cortex (n=7), basal ganglia (n=7), or brain stem or cerebellum (n=2). The lesions were single (n=3) or multiple (n=15), and in 17 patients were less than 1cm in diameter in regions other than the cerebral cortex. In six of these patients, lesions of 1-4cm in diameter in this region were combined, and one occurred in the cerebral cortex only. Cerebral atrophy was seen in 16 patients (62%), in ten of whom there was no past history of treatment with steroids for more than six months. In 15 patients (58%), contrast-enhanced MR image revealed diffuse enhancement of the basal ganglia or intravascular enhancement. In no case were MRI findings normal. The primary mainfestations of neuropsychiatric lupus are multifocal ischemia or infarctions in the cerebral cortex, and subcortical and deep white matter, and the cerebral atrophy. Contrast-enhanced MR images also demonstrated diffuse enhancement of the basal ganglia and intravascular enhancement, both thought to be related to the congestion due to the stagnation of cerebral blood flow.

To evaluate the CT findings of bronchial anthracofibrosis. Fourteen patients with bronchoscopically confirmed anthracofibrosis were involved in this study. CT findings (n=3D12) were retrospectively analysed; the pattern, distri-bution and extent of bronchial and parenchymal abnormalities and additional findings such as mediastinal lymphadenopathy and pleural effusion were assessed. Age, sex, and occupational and disease history were history were also reviewed. Patients were aged between 63 and 95 (mean, 71.3) years, and ten were female. Only one patient had an occupational history, but four had a history of pulmonary tuberculosis. Frequent radiologic findings were bronchial wall thickening(n=3D6), atelectasis(n=3D8), mediastinal lymphad-enopathy(n=3D7) and mass(n=3D4). Other accompanying findings were bronchial wall calcification(n=3D3), consolidation(n=3D2) and pleural effusion(n=3D2). Right upper (n=3D7) and right middle lobe(n=3D7) were the most commonly involved sites, and multifocal involvement (n=3D7) was frequent. Bronchial wall thickening, atelectasis and mediastinal lymphadenopathy were characteristic CT findings of anthracofibrosis. When such findings are noted in older or aged female patients, anthracofibrosis should be included in the differential diagnosis

A case of dysplastic gangliocytoma of the cerebellum, or Lhermitte-Duclos disease, is reported along with its CT findings, and the cases so far reported in the literature are reviewed. This is the 50th case report since the first description in 1920. This 61-year-old female had suffered from right hemifacial spasms for more than 20 years and from bilateral tinnitus with auditory disturbances for two years. Four years before admission, she underwent gastric resection and cancer chemotherapy for gastric cancer. Plain craniograms showed a thinned and ballooned occipital squama on the right side. Vertebral angiograms revealed a large tumor stain, with early venous filling, in the right posterior fossa. A CT scan showed a large, low-density mass, with small calcified areas in it, in the right posterior fossa. A postcontrast CT scan revealed no contrast enhancement, except for dilated vascular enhancement, within the tumor. No hydrocephalus was observed. Metrizamide CT cisternography revealed a huge intraaxial mass compressing the brain stem. (J.P.N.).

Objective: The purpose of this study was to describe the tomographic findings of gastric gastrointestinal stromal tumor. Materials and methods: Fourteen patients with histopathologically and immunohistochemically confirmed gastric gastrointestinal stromal tumors, who had already been submitted to computed tomography scans before the treatment, were evaluated in the period between January 1999 and December 2006. The following tomographic variables were analyzed: lesion topography, size/dimensions, homogeneity, contour, margins, morphology, pattern and intravenous contrast-enhancement intensity, growth pattern, invasion of adjacent organs, presence of ulceration, fistula, calcifications, mesenteric fat infiltration, lymphadenomegaly and presence of distant metastasis. Results: Tumors were found in the body (57.1%) or in the gastric fundus (42.9%), with sizes ranging between 6.0 cm and 23.0 cm (mean, 11.5 cm). Predominantly extra luminal growth was observed in 57.1% of cases and intra/extra luminal in 35.7%. Subtle contrast-enhancement was observed in 50%, moderate in 50%, and heterogeneous in 64.3% of cases. Additionally, central hypodensity was observed in 64.3%, invasion of adjacent organs in 42.9%, and hepatic metastasis in 7.2% of cases. Conclusion: In the present study, the majority of tumors were found in the gastric body, with an average size of 11.5 cm, presenting with central hypodensity, heterogeneous contrast-enhancement and predominantly extraluminal growth.

Myositis ossificans circumscripta (MOC) is a rare benign neoplasm located in soft tissues that, most of the time, appears after a local trauma. The positive diagnosis of MOC may be challenging on CT or MRI findings. We report on an atypical case of a spontaneous nontraumatic MOC in a 54-year-old man, located in the longus supinatus muscle diagnosed with MRI and F-18 FDG PET/CT findings. Rarely described F-18 FDG PET/CT features in MOC are presented. Pattern of avid FDG focus on PET/CT, that may wrongly suggest osteosarcoma, is presented.

Huntington's disease (HD) is a degenerative genetic disorder with autosomal-dominant transmission. The triad of symptoms of this disease consists of psychiatric disorders, jerky movements, and dementia. Oropharyngeal dysphagia, which is more evident with disease progression, is also present. Few studies have addressed the swallowing characteristics using objective analysis in this population. The purpose of this research was to describe the swallowing endoscopic findings of the pharyngeal phase in HD. This is a cross-sectional study addressing a clinical case which included two individuals of the same family, male, 32 and 63 years old, designated as individual A and individual B, with progression of the disease for five and 13 years, respectively. Consistent liquid, nectar, and puree were offered during the evaluation. There was presence of posterior oral spillage in liquid and nectar, small amount of pharyngeal residues, and no laryngeal penetration or aspiration in the individuals with HD in this study.

Transcutaneous electrical nerve stimulation (TENS) is an electrophysical modality used for pain management. This study investigated the dose response of different TENS intensities on experimentally induced pressure pain. One hundred and thirty TENS naïve healthy individuals (18-64 years old; 65 males, 65 females) were randomly allocated to 5 groups (n = 26 per group): Strong Non Painful TENS; Sensory Threshold TENS; Below Sensory Threshold TENS; No Current Placebo TENS; and Transient Placebo TENS. Active TENS (80 Hz) was applied to the forearm for 30 minutes. Transient Placebo TENS was applied for 42 seconds after which the current amplitude automatically reset to 0 mA. Pressure pain thresholds (PPT) were recorded from 2 points on the hand and forearm before and after TENS to measure hypoalgesia. There were significant differences between groups at both the hand and forearm (ANOVA; P = .005 and .002). At 30 minutes, there was a significant hypoalgesic effect in the Strong Non Painful TENS group compared to: Below Sensory Threshold TENS, No Current Placebo TENS and Transient Placebo TENS groups (P TENS and No Current Placebo TENS groups at the hand (P = .001). There was no significant difference between Strong Non Painful TENS and Sensory Threshold TENS groups. The area under the curve for the changes in PPT significantly correlated with the current amplitude (r(2) = .33, P = .003). These data therefore show that there is a dose-response effect of TENS with the largest effect occurring with the highest current amplitudes. This study shows a dose response for the intensity of TENS for pain relief with the strongest intensities showing the greatest effect; thus, we suggest that TENS intensity should be titrated to achieve the strongest possible intensity to achieve maximum pain relief.

Full Text Available Malaria is an infectious disease caused by protozoa of the genus Plasmodium. Cutaneous lesions in malaria are rarely reported and include urticaria, angioedema, petechiae, purpura, and disseminated intravascular coagulation (DIC. Here, five malaria cases associated with cutaneous lesions have been described. Out of the five cases of malaria, two were associated with urticaria and angioedema, one case was associated with urticaria, and other two were associated with reticulated blotchy erythema with petechiae. Most of the cutaneous lesions in malaria were nonspecific and reflected the different immunopathological mechanism in malarial infection.

Full Text Available Abstract Objective: The present study was aimed at investigating bone involvement secondary to rotator cuff calcific tendonitis at ultrasonography. Materials and Methods: Retrospective study of a case series. The authors reviewed shoulder ultrasonography reports of 141 patients diagnosed with rotator cuff calcific tendonitis, collected from the computer-based data records of their institution over a four-year period. Imaging findings were retrospectively and consensually analyzed by two experienced musculoskeletal radiologists looking for bone involvement associated with calcific tendonitis. Only the cases confirmed by computed tomography were considered for descriptive analysis. Results: Sonographic findings of calcific tendinopathy with bone involvement were observed in 7/141 (~ 5% patients (mean age, 50.9 years; age range, 42-58 years; 42% female. Cortical bone erosion adjacent to tendon calcification was the most common finding, observed in 7/7 cases. Signs of intraosseous migration were found in 3/7 cases, and subcortical cysts in 2/7 cases. The findings were confirmed by computed tomography. Calcifications associated with bone abnormalities showed no acoustic shadowing at ultrasonography, favoring the hypothesis of resorption phase of the disease. Conclusion: Preliminary results of the present study suggest that ultrasonography can identify bone abnormalities secondary to rotator cuff calcific tendinopathy, particularly the presence of cortical bone erosion.

Perineal nodular indurations ("accessory testicles") in cyclists. Fine needle aspiration cytologic and pathologic findings in two cases.

Vuong, P N; Camuzard, P; Schoonaert, M F

1988-01-01

The cytologic and histologic findings from two cases of perineal nodular indurations observed in two cyclists are reported. These lesions, also referred to as "accessory testicles" or "third testicle" or "ischial hygromas" of cyclists, consist of a localized aseptic area of necrosis with pseudocyst formation involving connective tissue in the superficial fascia of the perineum. These histologic findings, which were seen in the subsequent surgical specimens in these two cases, were reflected in the fine needle aspiration findings. The aspirates contained few cellular elements, mainly a few vacuolated histiocytes, against a background of fibrinous material. These indurations, which develop as a result of repeated, chronic microtrauma to the perineum impressed by the vibration of the saddle of the bicycle, constitute an authentic handicap for the professional cyclist and are a contraindication to cycling for amateur cyclists.

We report a rare case of CNS vasculitis associated with Goodpasture's syndrome in a 34-year-old man, who presented with a seizure and sudden onset of right sided weakness. He also had recurrent hemoptysis of one month's duration. Goodpasture's syndrome is histologically diagnosed by intense linear deposits of IgG along the glomerular basement membrane in both renal and lung tissues. oodpasture's syndrome is a rare disease, characterized by rapidly progressive glomerulonephritis, diffuse pulmonary hemorrhage and circulating antiglomerular basement membrane antibody (anti-GBM antibody). Central nervous system (CNS) manifestations in Goodpasture's syndrome are extremely rare, with only a few cases having been reported in the literature (8 10). Therefore, we present our imaging findings of CNS vasculitis associated with Goodpasture's syndrome, together with a review of the relevant literature. In summary, CNS vasculitis associated with Goodpasture's syndrome is extremely rare. Awareness of the imaging findings, as well as the clinical significance of CNS vasculitis associated with Goodpasture's syndrome, can be helpful in making the correct diagnosis and subsequent management of this rare condition

Full Text Available We systematically analyze audio key finding to determine factors important to system design, and the selection and evaluation of solutions. First, we present a basic system, fuzzy analysis spiral array center of effect generator algorithm, with three key determination policies: nearest-neighbor (NN, relative distance (RD, and average distance (AD. AD achieved a 79% accuracy rate in an evaluation on 410 classical pieces, more than 8% higher RD and NN. We show why audio key finding sometimes outperforms symbolic key finding. We next propose three extensions to the basic key finding system—the modified spiral array (mSA, fundamental frequency identification (F0, and post-weight balancing (PWB—to improve performance, with evaluations using Chopin's Preludes (Romantic repertoire was the most challenging. F0 provided the greatest improvement in the first 8 seconds, while mSA gave the best performance after 8 seconds. Case studies examine when all systems were correct, or all incorrect.

The authors report the findings of Aicardi syndrome, a disease of unknown etiology composed of multiple spasms, chorioretinal lacunae and agenesis of the corpus callosum. They present a case of Aicardi syndrome with characteristic clinical presentation and magnetic resonance imaging findings. The disease, despite being considered rare, has characteristic imaging findings. Over the past years magnetic resonance imaging has improved its ability in demonstrating other findings besides agenesis of the corpus callosum, making the radiologist's role very important in the diagnostic suspicion of this disease.

Kwon, Tae Hee

1999-01-01

To evaluate the sonographic findings of the heterotopic pregnancy which is increasing recently. Thirty-nine cases of heterotopic pregnancy after ovulation induction and IVF-ET (In Vitro Fertilization-Embryo Transfer) during the recent 3 years were analyzed. They were diagnosed by ultrasonography and proved surgically afterwards. Sonographic findings were analyzed focusing on gestational week of intrauterine pregnancy and location of ectopic pregnancy. In particular, adnexal mass was evaluated with regard to size and the characteristic findings such as ectopic gestational sac (echogenic ring). Also, overian cyst and fluid collection in cul-de-sac space were reviewed carefully. Heterotopic pregnancy was proved surgically by salpingectomy in 33 cases and by resection of cornus in six cases. Sonographic diagnosis using transvaginal ultrasound was made from five weeks to nine weeks two days (six weeks and four days in average) from last menstral period in all 39 cases. Ectopic pregnancy was identified in ampullary part in 29 cases, in the isthmic portion of tube in four cases and in the cornus of uterus in six cases. The intrauterine pregnancy was diagnosed by identifying the intrauterine gestational saccontaining a yolk sac in seven cases and the embryo with fetal heart beat in the remaining 32 cases. Adnexal masses of heterotopic pregnancy were less than 3 cm in diameter in 2 cases (57%), 3-4 cm in 11 cases (28%) and more than 4 cm in 6 cases (15%). A characteristic finding of ectopic mass was echogenic ring which was visible in 33 (84.6%) cases by transvaginal ultrasound. Six cases had pelvic hematosalpinx and two had pelvic hematoma. Of 10 cases (26%) which were identified to have ovarian hyperstimulation syndrome, eight (21%) had large amount of fluid collection in cul-de-sac and abdomen. Ultrasonographic identification of the intrauterine pregnancy and the ectopic chorion ring is effective for the early diagnosis of the heterotopic pregnancy.

A case of acute ergotism with angiographic demonstration of bilateral femoral artery involvement is reported. A 27-year-old married woman was admitted because of sudden onset of severe pain in both flanks and lower legs, followed by numbness and coldness of the skin on both legs. The attack occurred after the administration of ergot tartrate as postpartum care. Femoral arteriography was performed on 10th day of illness with the Seldinger technic. The femoral arteries were generally smaller in caliber than normal. There was no definite evidence of occlusive disease. Findings were more or less symmetrical and extended to lower legs where only fine branches were visualized. The final diagnosis was diffuse vasospasm due to acute ergotism with secondary occlusion of the arteries of lower leg bilaterally.

Ten years' experience in determining internal contamination among plutonium laboratory workers

International Nuclear Information System (INIS)

Deworm, J.; Fieuw, G.

1976-01-01

Glove boxes in plutonium laboratories are fitted with ''sniffers'' (air samplers), which evaluate atmospheric contamination. The results of the measurements over a ten-year period of operation are available, and cases of detection in this way of air contamination exceeding the maximum permissible concentrations are exceptional. During contamination aerodynamic particle diameters of 1 - 4 μm were measured. The concentration and characteristics of the aerosol have made it possible to ascertain the inhalable fraction and to estimate the pulmonary and systemic burden in workers. The workers exposed in the laboratories undergo a urine test each month. The results obtained show that there is little risk of internal contamination without the person concerned being aware of an abnormal situation. In the majority of cases it is possible to take proper precautions and to collect the data necessary for evaluating the body burden. Three cases of specific contamination are examined in detail: contamination by plutonium and americium from a non-identified source, detected by routine urine analysis; contamination by inhalation of plutonium; an injury to the left forefinger, accompanied by plutonium contamination.

Technology transfer is crucial to reduce the carbon intensity of developing countries. Enabling frameworks need to be in place to allow foreign technologies to flow, to be absorbed and to bring about technological change in the recipient country. This paper contributes to identifying these enabling factors by analysing 10 case studies of low-carbon technology transfer processes based in Chile. Our findings show the importance of strong economic and institutional fundamentals, a sound knowledge base, a sizable and stable demand and a functioning local industry. Policy recommendations are derived to improve the penetration of foreign low-carbon technologies in developing countries, focusing on the particularities of small and medium emerging economies. - Highlights: ► We analyse 10 case studies of low carbon technology transfer to Chile. ► We identify enablers of technology transfer to developing countries. ► We provide policy recommendations focusing on small and medium economies.

Subdural hematomas (SDH) are relatively common and the typical CT findings according to the age of them are well established. The CT findings of 82 patients with SDHs were reviewed and compared with the operative findings. The results were as follow: 1. The most common cause of SDHs was the direct trauma which was noted in 60 cases (73.2%). 2. The atypical CT findings of the mixed density were seen in 19 cases (23.2%), including acute SDH 7 cases (20%), subacute SDH 5 cases (41.7%), and chronic SDH 7 cases (20%). 3. The possible causes of the mixed density in acute SDH were unclotted blood in early stage of hematoma development or serum extruded during the early phase of clot retraction. But the possibility of cerebrospinal fluid within subdural space due to an arachnoid tear could not be excluded. 4. The possible causes of the mixed density in subacute and chronic SDH were serum extruded during the hematoma resolution and rebleeding. 5. Wall enhancement of hematomas was noted in 3 cases (25%) of subacute SDHs and 15 cases (42.9%) of chronic SDHs. 6. Most of SDHs was crescentic in shape, but lenticular in 4 cases (4.9%). Midline shift and compression of ventricles were proportional to the maximum thickness of SDHs. There were seen ipsilateral dilatation of ventricles in 9 cases (11.0%) and brain edema in 11 cases (13.4%)

To evaluate the CT findings of focal organizing pneumonia and to correlate them with pathologic findings to help differentiating from lung cancer. We evaluated radiologic and pathologic findings of five patients with solitary pulmonary nodule which were confirmed as focal organizing pneumonia pathologically. On CT scan, focal organizing pneumonia had irregular margin contacting the pleura in all five cases. The shape of the nodules were spherical to wedge or elliptical and the size from 3.5cm to 5.5cm(average 4.2 cm) in largest diameter. On postcontrast CT scan, all nodules showed enhancement and four cases showed central low density components. Two nodules contained air within the nodule. In four cases, pleural changes such as effusion and/or focal thickening were noted. No lymphadenopathy was found in all cases. Pathologically, the enhancing portion on CT showed findings of organizing pneumonia such as granulation tissue with fibroblast proliferation in alveolar space and interstitial thickening. The central low density areas on CT were due to ischemic necrosis, abscess and exudate, transudate and infiltration of foamy histiocyte. The possibility of focal organizing pneumonia should be considered when peripherally located solitary pulmonary nodule had enhancing component with no combined lymphadenopathy on CT scan.

Using TENS for pain control: the state of the evidence

Science.gov (United States)

Vance, Carol GT; Dailey, Dana L; Rakel, Barbara A; Sluka, Kathleen A

2014-01-01

Summary Transcutaneous electrical nerve stimulation (TENS) is a nonpharmacological intervention that activates a complex neuronal network to reduce pain by activating descending inhibitory systems in the central nervous system to reduce hyperalgesia. The evidence for TENS efficacy is conflicting and requires not only description but also critique. Population-specific systemic reviews and meta-analyses are emerging, indicating both HF and LF TENS being shown to provide analgesia, specifically when applied at a strong, nonpainful intensity. The purpose of this article is to provide a critical review of the latest basic science and clinical evidence for TENS. Additional research is necessary to determine if TENS has effects specific to mechanical stimuli and/or beyond reduction of pain and will improve activity levels, function and quality of life.

2012-02-01

Multiple and inappropriate medications are often the cause for poor health status in the elderly. Medication reviews can improve prescribing. This study aimed to determine if a ten minute medication review by a general practitioner could reduce polypharmacy and inappropriate prescribing in elderly patients. A prospective, randomised study was conducted. Patients over the age of 65 (n = 50) underwent a 10-minute medication review. Inappropriate medications, dosage errors, and discrepancies between prescribed versus actual medication being consumed were recorded. A questionnaire to assess satisfaction was completed following review. The mean number of medications taken by patients was reduced (p < 0.001). A medication was stopped in 35 (70%) patients. Inappropriate medications were detected in 27 (54%) patients and reduced (p < 0.001). Dose errors were detected in 16 (32%). A high level of patient satisfaction was reported. A ten minute medication review reduces polypharmacy, improves prescribing and is associated with high levels of patient satisfaction.

Hansen's disease (leprosy) remains an important health problem in Brazil, where 34,894 new cases were diagnosed in 2010, corresponding to 15.3% of the world's new cases detected in that year. The purpose of this study was to use home visits as a tool for surveillance of Hansen's disease in a hyperendemic area in Brazil. A total of 258 residences were visited with 719 individuals examined. Of these, 82 individuals had had a previous history of Hansen's disease, 209 were their household contacts and 428 lived in neighboring residences. Fifteen new Hansen's disease cases were confirmed, yielding a detection rate of 2.0% of people examined. There was no difference in the detection rate between household and neighbor contacts (p = 0.615). The two groups had the same background in relation to education (p = 0.510), household income (p = 0.582), and the number of people living in the residence (p = 0.188). Spatial analysis showed clustering of newly diagnosed cases and association with residential coordinates of previously diagnosed multibacillary cases. Active case finding is an important tool for Hansen's disease control in hyperendemic areas, enabling earlier diagnosis, treatment, decrease in disability from Hansen's disease and potentially less spread of Mycobacterium leprae.

The purposes of our study were to find out characteristic ultrasonographic findings of gynecomastia and to analyze age distribution, causative factors of gynecomastia. For these purposes, medical records of 39 male patients with gynecomastia were reviewed and sonographic findings of 13 cases of gentamycin were analyzed. Gynecomastia was found most commonly in teenagers and commonly in twenties. Almostly, it occurred without any evident etiology and classified as idiopathic or pirbuterol type. Less frequently, it occurred due to drug administration, systemic disease, or male hormone deficiency. Unilateral involvement was seen in 29 cases; 17cases involving the left and 12 cases the right. Bilateral involvement was seen in 10 cases. Sonographically,gynecomastia appeared as hypoechoic or intermediate echoic mass with various shape in the subareolar area. One case showed diffuse fatty breast pattern without definable mass. On sonographic evaluation, prominent nipple should not be misinterpreted as a breast mass. For the correct diagnosis of gynecomastia, both side breasts should be evaluated for comparison

This research was designed to provide an in-depth exploration of the perceptions of optometrists relating to the challenges of glaucoma case finding in the Irish health-care system. A survey was developed, piloted and distributed for anonymous completion by optometrists registered to practise in Ireland. The survey included 10 five-level Likert items exploring potential barriers to glaucoma detection and a free-text box for participants to comment more broadly. One hundred and ninety-nine optometrists (27 per cent of registrants) responded to the survey. Among the barriers identified, there was notable agreement (71 per cent) with the need for extra training on glaucoma detection. Logistic regression showed that optometrists without postgraduate qualifications were more likely to agree with the need for extra training (OR 3.2, 95 per cent CI 1.3-8.1). Respondents largely agreed (61 per cent) that patient unwillingness to pay additional fees for supplementary glaucoma-specific tests was also a barrier. Appointment times of less than 30 minutes were significantly associated with six of the 10 proposed barriers to glaucoma detection. A logistic regression analysis (n = 179) confirmed that the time allotted per appointment was a significant predictor of the agreement time of optometrists as a barrier (χ 2 [1] = 13.52, p glaucoma indicates that optometrists wishing to increase their scope of practice in the new legislative environment in Ireland may more actively seek training in areas of interest. The responses also indicate a lack of funding for the level of diagnostic testing required for accurate glaucoma diagnosis. Recent increases in the state's eye examination fees look likely to address the identified time and financial barriers to glaucoma detection in Ireland. Future work should look to analyse the effects of increased funding on optometric case finding for glaucoma. © 2017 Optometry Australia.

Small cell neuroendocrine carcinoma of the uterine cervix is a rare primary neoplasm, accounting for less than 5% of all uterine cervical cancers. The tumor is known to have an aggressive behavior and poor prognosis. In this article, we present the MRI findings of 5 cases of pathologically-proven small cell neuroendocrine carcinoma of the uterine cervix, including diffusion-weighted images.

Five new cases and one previously reported case of the Coffin-Siris syndrome are described. These cases plus the remaining four already published bring to ten the number of cases available for scrutiny. Constant features (100% frequency) include variable degrees of mental retardation, nail hypoplasia or absence with predominantly fifth digit involvement, hypotonia, infancy feeding problems, and retarded bone age. Frequent features (75% to 90%) include postnatal growth deficiency, microcephaly, wide nasal tip and mouth, prominent lips, eyebrow/eyelash hypertrichosis, and scalp hair hypotrichosis. Significant but less frequent findings include short philtrum (50%, scoliosis (40%), decreased fetal activity (40%), smallness for gestational age (30%), and congenital heart defects (30%). We found the craniofacial phenotype to be mild in the young infant, but progressively more characteristic with age. Autosomal recessive inheritance is suspected on the basis of our brother-and-sister pair.

This case illustrates and supports the pathophysiological hypotheses that were previously proposed for the coexistence of these three abnormalities

Effective Bug Finding

DEFF Research Database (Denmark)

Rivas, Iago Abal

Lightweight bug finders (also known as code scanners) are becoming popular, they scale well and can find simple yet common programming errors. It is now considered a good practice to integrate these tools as part of your development process. The Linux project, for instance, has an automated testing...... service, known as the Kbuild robot, that runs a few of these code scanners. In this project, I have carefully studied tens of historical Linux bugs, and I have found that many of these bugs, despite being conceptually simple, were not caught by any code scanning tool. The reason is that, by design, code...... by matching temporal bug-patterns against the control-flow graph of this program abstraction. I have implemented a proof-of-concept bug finder based on this technique, EBA, and confirmed that it is both scalable and effective at finding bugs. On a benchmark of historical Linux double-lock bugs, EBA was able...

The authors made comparative studies of CT findings with upper GI series and surgical findings in 20 cases of histologically proven gastric cancers. The identification of chickening of gastric wall and local and remote metastasis by CT was thought to be great value in treatment planning and prediction of prognosis of the patients. The results were as follows: 1. Of 20 cases, 19 cases demonstrated thickening of gastric wall. Among 3 cases suggested as early cancer on upper GI series, 2 cases demonstrated thickened gastric wall on CT and it was proved to be advanced cancer at surgery. 2. Out of 8 cases showed no definite metastasis on CT, 4 cases had malignant infiltration histologically in the regional lymph nodes. But they were less than 1.5 cm in diameter. 3. The frequency order of remote metastasis found by CT was pancreas, liver, left adrenal gland and lung in organs and retroperitoneal, retrocrural and regional nodes in lymph nodes.

The purpose of this study is to determine characteristic CT findings in renal abscess. Twenty cases of renal abscess were retrospectively analyzed for CT findings relating to the shape and extent of the abscess, change of nephrogram, peripheral rim enhancement, wedge-shaped enhancement on delayed scans, enlargement of the kidney involved and associated findings. Seven patients had a renal abscess at the right kidney, nine at the lift kidney and two bilaterally. The abscesses were round in 18 cases and finger-like in two. Rim enhancement around renal abscess was seen in four cases (20%). Changes in the nephrogram around the abscess were seen in 12 cases (60%). In all six patients who had undergone delayed postcontrast scans, wedge-shaped enhancement was shown around the abscess (100%). In the observation of the extent of renal abscesses, 14 cases were within the kidney, six cases extended the beyond renal capsule, and two were loculated in the renal fascia itself. Renal enlargement was seen in nine cases (45%). These results suggest that CT findings such as delayed wedge-shaped enhancement, change of nephrogram, peripheral rim enhancement, renal enlargement, and associated findings are valuable for diagnosis, and that CT also gives information concerning the extent, evolution and complication of a renal abscess

Full Text Available Background and Design: Morphea is an inflammatory skin disease seen more frequently than systemic sclerosis in pediatric patients. Important functional deficiencies and cosmetic deformities may develop especially due to linear morphea. Patients may have accompanying extracutaneous involvement, family history of rheumatologic diseases and abnormalities in laboratory parameters like positive ANA and RF. It is important to evaluate pediatric patients accordingly and to carry out further examinations.Data about pediatric morphea in Turkish population could not be found in the literature. We aimed to evaluate epidemiological, clinical and laboratory findings, to compare the data with those in the literature and to propose a model for Turkish pediatric morphea which can be supported by future multicenter national studies. Materials and Methods: Fourteen pediatric morphea patients, 3 males and 11 females under the ageof 18, followed up at Uludag University, Medical Faculty, Dermatovenereology Department between 2000-2010 were enrolled in the study. Inclusion criterion was age under 18 years at diagnosis. Epidemiological, clinical and laboratory findings were analyzed retrospectively. Results: Only 3 patients were males. The mean age at disease onset was 9.5 years. The mean duration of disease was 21 months. Most frequent type was linear morphea. Two patients had contracture, one had shortness in the left lower extremity, and 4 patients had livedo reticularis. Raynaud’s phenomenon was positive in one case. Trauma and sunburn were the trigger factors detected. Behcet’s disease was reported in the father of one patient. One case was RF positive. Five patients had positive ANA in titers of 1/100, while a patient with generalised morphea had significantly higher titer (1/1000. Antihistone antibodies were positive in one patient and 2 cases were Lyme IgM positive.Conclusion: Early diagnosis and therapy are important since childhood morphea can cause
