Abstract Clinically significant sellar cysts unrelated to pituitary adenomas are uncommon. Intracranial cholesteatomas are also rare and are most common in the middle ear and mastoid region. We report an even rarer case of cholesteatoma in the sellar region—a challenging diagnosis guided by clinical presentations, radiological signs, and biopsy, aiming at emphasize the importance of considering cholesteatoma when making differential diagnoses of sellar lesions. We present a case of cholesteatoma in the sellar region in a 56-year-old man with hypopituitarism, diabetes insipidus, and cystic imaging findings. It was difficult to make an accurate diagnosis before surgery. We present detailed analysis of the patient's disease course and review pertinent literature. The patient underwent a surgical exploration and tumor resection through a transsphenoidal approach. Pathologic results revealed a cholesteatoma. The patient's symptoms improved a lot after surgery, and the postoperative period was uneventful. Taken together, the lesion's imaging appearance, pathological characteristics, and clinical features were all unique features that lead to a diagnosis of cholesteatoma. As we did not see such reports by Pubmed and EMBASE, we believe this is the first reported case of sellar cholesteatoma presenting in this manner. This article emphasized that cholesteatomas, although rare, should be considered part of the differential diagnosis of sellar lesions. PMID:26962793

2016-01-01

Melorheostosis is a benign bone dysplasia affecting predominantly the appendicular skeleton and adjoining soft tissues. The diagnosis can be established on plain radiographs alone and advanced imaging modalities can be avoided. We hereby report a rare case of melorheostosis affecting the foot with a review of the role of various imaging modalities in diagnosis of this rare bone dysplasia. We present the case of a 29 years old man who was diagnosed with melorheostosis affecting his left foot. The patient presented to the outpatient department of our tertiary care referral hospital with complains of pain in the left ankle and foot with imaging and evaluation done at a primary center. The radiograph revealed an irregular, longitudinal extraosseous hyperostosis along the body of the calcaneum and the metacarpals which was consistent with the classical radiological description of melorheostosis. The CT, MRI and bone scan findings corroborated our primary diagnosis. The purpose of this case report is to review the features of this rare disorder affecting the foot, on multiple imaging modalities and emphasizing the role of conventional radiology in its diagnosis.

Male ductal carcinoma in situ presenting as bloody nipple discharge: a case report and literature review.

PubMed

Simmons, Rache M

2002-01-01

Male breast carcinoma accounts for 1% of all diagnosed breast carcinoma. Pure ductal carcinoma in situ in men is extremely rare. Unfortunately, male breast cancer is often diagnosed at a late stage because of the minimal awareness of presenting symptoms by the patient and sometimes by the health care provider. Because of this late presentation, the overall prognosis is less favorable. This case is presented to emphasize the importance of recognizing bloody nipple discharge as a clinical sign of male ductal carcinoma in situ and an opportunity for early diagnosis.

Gorlin-Goltz syndrome (GGS) seems to be unusual in black persons. The authors present an Afro-Brazilian family case report of GGS. The main complaint of the index case was a painless swelling of the left mandible, which was diagnosed as an odontogenic keratocyst. Further classical features of the Syndrome were present in this patient. Other two family members were diagnosed as cases of GGS and one of them presented 11 clinical findings characteristic of the syndrome. From the three cases reported, two of them presented five major diagnostic criteria for the GGS, and the diagnosis was only made because of an oral complaint. This case series emphasizes the importance of carefully examining the patient and close relatives for signs of GGS, even if they belong to an ethnic group in which this diagnosis is unusual. © 2014 Special Care Dentistry Association and Wiley Periodicals, Inc.

Integrating Efficiency of Industry Processes and Practices Alongside Technology Effectiveness in Space Transportation Cost Modeling and Analysis

NASA Technical Reports Server (NTRS)

Zapata, Edgar

2012-01-01

This paper presents past and current work in dealing with indirect industry and NASA costs when providing cost estimation or analysis for NASA projects and programs. Indirect costs, when defined as those costs in a project removed from the actual hardware or software hands-on labor; makes up most of the costs of today's complex large scale NASA space/industry projects. This appears to be the case across phases from research into development into production and into the operation of the system. Space transportation is the case of interest here. Modeling and cost estimation as a process rather than a product will be emphasized. Analysis as a series of belief systems in play among decision makers and decision factors will also be emphasized to provide context.

Root, Brandon K; Schartz, Derrek A; Calnan, Dan R; Hickey, William F; Bauer, David F

2018-06-01

Spinal epidural hematomas are uncommon in children. The diagnosis can be elusive as most cases present without a history of trauma, while symptoms can be atypical. We encountered a 35-month-old male presenting with nonspecific symptoms and no history of trauma. He later developed unilateral miosis and ptosis; MRI discovered a subacute cervicothoracic epidural which was promptly evacuated. The patient made an excellent recovery. We emphasize the frequent absence of identifiable trauma and the importance of thorough imaging when this entity is suspected. Miosis and ptosis, likely representing a partial Horner syndrome, is an extremely rare presentation, this being one of the only reported cases.

Retropharyngeal abscess with mediastinal extension in an infant--still existing?

PubMed

Bakshi, Rijuneeta; Grover, Gogia

2009-03-01

The objective of the present case report was to note that despite the low incidence of retropharyngeal abscess in the present antibiotic era, children, especially infants, can develop this condition. If early diagnosis is missed, the abscess may extend into the mediastinum and can be life threatening. Case reports of mediastinal abscess in the past literature along with the current case. The present case was successfully managed by surgical drainage of the abscess via transcervical route along with intravenous antibiotic therapy, and the recovery was uneventful. Although the incidence of retropharyngeal abscess has declined with the widespread use of antibiotics, the presenting symptom can be overlooked in a pediatric population, especially infants, and can extend along the fascial planes to the mediastinum when the recovery becomes difficult. The present report is an effort to draw attention to this life-threatening complication of retropharyngeal abscess, emphasize the role of early diagnosis, and prompt surgical management.

2008-01-01

Introduction Current trends in dementia research focus on early and accurate diagnosis. In clinical practice however, this is not always possible, as multiple underlying pathologies produce mixed dementia syndromes. Furthermore, patients with severe dementia are often underestimated. Case presentation We present a case of a 71 year old Caucasian male with severe Alzheimer's Disease, bedridden and fully dependent in activities of everyday living, whose general cognitive function is almost intact. We emphasize on the diverse underlying pathologies contributing to this intriguing clinical presentation and to diagnostic uncertainty. Conclusion Understanding the complexity of the dementia process in every patient using a multidimensional approach, contributes to more rational management strategies and finally to high quality care for patients and caregivers.

2017-11-06

Leucoderma syphiliticum (LS), originally described as syphilide pigmentaire, encompasses a spectrum of dyschromic lesions that emerge during the course of secondary syphilis. Very few case reports are available in modern biomedical databases. We present the case of a 57-year-old HIV-infected male patient who presented with several round to oval, non-scaling, slightly raised and well-demarcated hypochromic lesions scattered over the trunk, abdomen, dorsum, and arms. Prior non-treponemal tests were negative for syphilis, but novel studies yielded positive results at high titers. Skin lesions slowly regressed and the hypochromic areas repigmented a few weeks after benzathine penicillin G treatment. This is the first report of LS in an HIV-infected patient. A review of modern and ancient literature was performed. The present case report emphasizes the need for clinicians to have a heightened awareness of the varied and unusual clinical phenotypes of syphilis.

Duggal, Shalini; Jain, Hemant; Tyagi, Amit; Sharma, Anuradha; Chugh, T D

2011-11-01

Rhodotorula is emerging as an important cause of nosocomial and opportunistic infections. We present two cases of Rhodotorula mucilaginosa fungemia diagnosed over a period of 3 months at our hospital. The first case was of a pre-term neonate in the neonatal ICU who presented with respiratory failure and sepsis. The second involved an adult female who had been injured in a road traffic accident requiring an operation for a hematoma and was later shifted to the medical ICU. For a new hospital like ours, finding two cases of Rhodotorula fungemia within a span of 3 months prompted us to describe them in this report. These cases emphasize the emerging importance of Rhodotorula mucilaginosa as a pathogen and the importance of identification and MIC testing for all fungal isolates recovered from the blood stream.

Langerhans cell histiocytosis (LCH) of the vulva is rare and even moreso in postmenopausal women. Twenty-six cases of primary vulvar LCH have been described in the current literature, and only 8 cases are in postmenopausal women. We report an additional case of primary vulvar LCH in a 59-yr-old woman with subsequent multiorgan involvement. In this article, we briefly describe the clinical presentation, histopathological findings, and immunohistochemistry results of vulvar LCH. We want to emphasize the importance of recognizing this entity in a woman with vulvar lesions both for the clinician and the pathologist.

2017-12-01

Self-inflicted explosive deaths due to detonation of fireworks are rare. In this case report, a peculiar case of an elderly male who discharged a firecracker inside his mouth, resulting in fatal blast induced craniofacial injuries, is described. There is paucity of published data describing fireworks-related suicidal and/or non-suicidal deaths. Even scantier data is present specifically describing fireworks-related blast induced neurotrauma and the mechanism(s) of injury involved in such cases. This case report emphasizes the severe damage that a commercially available explosive, the so-called "Gorilla Bomb", can cause, and raises questions about the relative ease of its acquisition.

2004-03-01

Jarcho-Levin syndrome, also known as spondylothoracic dysplasia and characterized by short trunk dwarfism, "crab-like" rib cage, with ribs and vertebral defects; it is not uncommon in Puerto Ricans. Many patients die in early infancy due to respiratory compromise associated to lung restriction and the reported cases emphasize mostly the skeletal malformations associated to the syndrome. We report the autopsy findings in a newborn with isolated Jarcho-Levin syndrome emphasizing pulmonary pathology. He was a pre-term male who died of respiratory failure at three hours old and, autopsy findings confirmed the clinical diagnosis. Internal examination showed hypoplastic lungs with normal lobation. The histological structure appeared normal and relatively mature; the diaphragm showed eventration and unilateral absence of musculature. This case shows the worst spectum of the Jarcho-Levin syndrome: pulmonary hypoplasia not compatible with extrauterine life. Since thoracic restriction is present during the fetal period, the degree of pulmonary hypoplasia probably defines survival beyond the neonatal period.

2018-05-01

Warthin tumor is the second most common salivary gland neoplasm. It occurs more commonly in males than in females. Malignant transformation in Warthin tumor is a rare but well-recognized phenomenon; however, the development or presentation of lymphoma in a Warthin tumor is rare. An 80-year-old man presented with painless mass of the right parotid gland of 2 years duration with recent ulceration of the overlying skin and right cervical lymphadenopathy underwent a surgical resection of parotid mass and biopsy of the periglandular lymph nodes. The histological diagnosis was malignant lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma, present within the stroma of a Warthin tumor, and also present within the adjacent lymph node. This case is the third reported case describing a collision of Warthin tumor and chronic lymphocytic leukemia/small lymphocytic lymphoma. It also emphasizes the importance of careful examination of the lymphoid stroma of these tumors.

Breast mass as the initial presentation of esophageal carcinoma: a case report

PubMed Central

Norooz, Mohammad Tayefeh; Ahmadi, Hamed; Zavarei, Mansour Jamali; Daryaei, Parviz

2009-01-01

Introduction Esophageal cancer is considered as a fatal malignancy. It mostly metastasizes to lung, liver, and bone while breast metastasis has been rarely reported. This is the fifth report of metastatic breast cancer from esophageal cancer, which differs from previous reported cases in terms of initial presentation with metastatic breast mass and no metastatic involvement of other organs. Case presentation We present a 35-year-old Caucasian woman who initially complained of a painful breast mass. Squamous pearls on cytologic evaluation suggested a metastatic lesion. Two months history of dysphagia was extracted through detailed interview with patient and further investigation revealed a stage IV esophageal squamous cell carcinoma. Conclusion In this case, breast lesion as an unusual presentation of esophageal carcinoma emphasizes the great role of thorough medical history taking and cytologic study in evaluating an accidentally detected breast mass. The increasing reports of breast metastasis in patients with esophageal carcinoma necessitate the careful breast examination in visits after treatment of the primary tumor. PMID:19829901

2010-01-01

We report a case of Hymenolepis diminuta infection in a 2-year-old child living in a suburban area of Catania, Italy. This case was initially referred to us as Dipylidium caninum infection, which was not cured after being treated twice with mebendazole. However, by analyzing the clinical presentation and stool samples we arrived to the diagnosis of H. diminuta infection. The case presented with atypical allergic manifestations which had never been reported as clinical features of symptomatic H. diminuta infection; remittent fever with abdominal pain, diffuse cutaneous itching, transient thoracic rash, and arthromyalgias. The patient was treated with a 7-day cycle of oral niclosamide, which proved to be safe and effective. This case report emphasizes that a correct parasitological diagnosis requires adequate district laboratories and trained personnel. In addition, we recommend the importance of reporting all H. diminuta infection cases, in order to improve knowledge on epidemiology, clinical presentation, and treatment protocols. PMID:20585535

Cysticercosis is a parasitic infestation caused by the pork tapeworm larval stage, Cysticercus cellulosae. The majority of the cases present in ocular, cerebral, and subcutaneous locations. We report the presence of cysticercosis inside the submandibular gland in association with squamous cell carcinoma of the inferior alveolar ramus of the mandible. To the best of our knowledge, this is the first case report documenting cysticercosis inside a salivary gland. A 65-year-old male presented with complaints of an ulcerative lesion on the inferior alveolar ramus present for 2 months. Histological examination revealed a keratinizing well-differentiated squamous cell carcinoma involving the alveolar margin and mandible. The histopathological examination of the submandibular gland revealed cysticercosis. This case emphasizes the importance of adequate sampling of all the tissues obtained for associated infectious disorders, more so in immunosuppressed patients, which will help the clinician to manage the case appropriately.

2014-01-01

Acute myocardial infarction (AMI) is usually seen in the setting of atherosclerosis and its associated risk factors. Myocardial infarction in the young poses a particular challenge, as the disease is less likely, due to atherosclerosis. We report the case of a 37-year-old female patient who presented with ST segment elevation anterolateral AMI. The only abnormality on routine blood investigation was raised hemoglobin and hematocrit. After further testing, she was diagnosed according to the World Health Organization (WHO) criteria with polycythemia vera. This case illustrates the importance of recognizing polycythemia vera as an important cause of thrombosis, which can present initially as AMI, and to emphasize the early recognition of the disease in order to initiate appropriate management strategies.

Three cases are described presenting with progressive contractures in whom the muscles felt firm and `woody' and a clinical diagnosis of myosclerosis was made in each case. A patient and his young sister were shown to be suffering from spinal muscular atrophy with superimposed, excessive proliferative activity of fibroblasts, and in these cases a beneficial effect of penicillamine was demonstrated. The third case with a clinical picture of myosclerosis was found on muscle biopsy to have extensive inflammatory infiltration of the connective tissue, and responded temporarily at least to high doses of corticosteroids. It is emphasized that several different disease entities can give rise to this clinical picture. Images PMID:4793163

Summary Hypothyroidism is a wide clinical spectrum disorder and only a few cases in literature show this. Rhabdomyolysis and acute renal impairment can be seen concurrently in a hypothyroid state. We report a case of severe hypothyroidism with poor drug compliance leading to rhabdomyolysis and acute kidney injury. Learning points: Hypothyroidism is a rare cause of acute kidney injury. In this case report, we studied a rare occurrence of acute renal impairment due to hypothyroidism with poor drug compliance, which induced rhabdomyolysis. Our report emphasized that thyroid status should be evaluated in patients with unexplained acute renal impairment or presenting with the symptoms of muscle involvement. PMID:27855234

2017-01-01

Introduction. Chromobacterium violaceum is an opportunistic human pathogen, associated with significant mortality, and has been reported in patients with chronic granulomatous disease (CGD), a genetic condition causing impaired phagocytosis. Case presentation. A 28-year-old man with a history of CGD presented with fever, pharyngitis, cervical lymphadenopathy and internal jugular vein thrombosis, following travel to the rural Solomon Islands. C. violaceum was recovered from his blood. The patient recovered after treatment with meropenem and trimethoprim/sulfamethoxazole. Conclusion. To the best of our knowledge, this is the first case report of internal jugular vein thrombophlebitis (Lemierre's syndrome) caused by C. violaceum in a patient with CGD. A review of the literature demonstrated that the diagnosis of C. violaceum preceded the diagnosis of CGD in the majority of cases. This case emphasizes the importance of this organism in patients with CGD who live in or visit tropical areas.

Mongolu, S; Sharp, P

2013-01-01

Although uncommon, lead poisoning should be considered as a differential diagnosis in cases of unexplained acute abdominal pain in both adults and children. We present the case of a 35-year-old Asian male who presented with abdominal pain and constipation secondary to lead poisoning. Initially, the source of lead exposure was not apparent; this was later found to be due to ingestion of an Ayurvedic herbal medicine for the treatment of infertility. Lead poisoning due to the ingestion of Ayurvedic remedies is well described. We discuss the diagnosis, pathophysiology and treatment of lead poisoning. This case illustrates one of the rarer medical causes of acute abdominal pain and emphasizes the need to take a thorough history (including specific questioning regarding the use of over-the-counter and traditional/ herbal remedies) in cases of suspected poisoning or drug toxicity.

2015-01-01

Lipomatous hemangiopericytomas are rare soft-tissue tumors that show areas of hemangiopericytoma like vascular pattern admixed with lipid containing cells. It is now considered a subtype of solitary fibrous tumor due to histopathological and immunohistochemical similarities. To date, only a few cases have been adequately reported in the medical literature. A case of lipomatous hemangiopericytoma in an 11-year-old female patient is presented and the clinical, histopathological and immunohistochemical features are discussed, along with a literature review. To the best of our knowledge, this is the first known case of a lipomatous hemangiopericytoma in a pediatric patient. Our case report further emphasizes that a number of studies should be evaluated to delineate hemangiopericytomas from solitary fibrous tumors. PMID:26097315

Background theory and specific coding designs for combined coding/modulation schemes utilizing convolutional codes and continuous-phase modulation (CPM) are presented. In this paper the case of r = 1/2 coding onto a 4-ary CPM is emphasized, with short-constraint length codes presented for continuous-phase FSK, double-raised-cosine, and triple-raised-cosine modulation. Coding buys several decibels of coding gain over the Gaussian channel, with an attendant increase of bandwidth. Performance comparisons in the power-bandwidth tradeoff with other approaches are made.

Hereditary Neuropathy With Liability to Pressure Palsies: Diverse Phenotypes in Childhood.

Harada, Yohei; Puwanant, Araya; Herrmann, David N

Hereditary neuropathy with liability to pressure palsies (HNPP) is a rare autosomal-dominant disorder that most commonly produces recurrent painless focal sensory and motor neuropathies often preceded by minor, mechanical stress, or minor trauma. Herein, we report 2 pediatric cases of HNPP with atypical presentations; isolated muscle cramping and toe walking. Electrophysiologic testing disclosed multifocal sensorimotor polyneuropathy with slowing of sensory conduction velocities in both cases, which prompted PMP 22 gene deletion testing. Multifocal sensorimotor electrophysiologic abnormalities, with slowing of sensory conduction velocities should raise consideration of HNPP in childhood. These case reports emphasize that the diagnosis of HNPP in children requires a high index of suspicion.

Metastases in the thyroid gland are very rare. Carcinoma lung is one of the tumours, which may metastasize to the thyroid. We report a 60-year-old lady with intrathyroid metastasis presenting as a solitary thyroid nodule. Fine needle aspiration cytology from the nodule showed features of metastatic adenocarcinoma. Further detail evaluation revealed primary lung adenocarcinoma with secondaries to adrenals, retroperitoneal and bilateral axillary nodes. This report emphasizes this unusual clinical presentation of carcinoma lung with wide spread secondaries; and a solitary thyroid nodule can be a presenting complain of a metastatic disease.

Synchronous adenocarcinomas of the colon presenting as synchronous colocolic intussusceptions in an adult

PubMed Central

2012-01-01

Intussusception is uncommon in adults. To our knowledge, synchronous colocolic intussusceptions have never been reported in the literature. Here we described the case of a 59-year-old female of synchronous colocolic intussusceptions presenting as acute abdomen that was diagnosed by CT preoperatively. Laparotomy with radical right hemicolectomy and sigmoidectomy was undertaken without reduction of the invagination due to a significant risk of associated malignancy. The final diagnosis was synchronous adenocarcinoma of proximal transverse colon and sigmoid colon without lymph nodes or distant metastasis. The patient had an uneventful recovery. The case also emphasizes the importance of thorough exploration during surgery for bowel invagination since synchronous events may occur. PMID:23241170

Background. Histoplasma capsulatum is the most common endemic mycosis in the United States and is a frequent cause of opportunistic infection in immunodeficient hosts. Histoplasmosis is most often self-limiting and goes unrecognized in the immunocompetent population but can progress to disseminated histoplasmosis in patients with an impaired immune system. Liver involvement as a part of disseminated histoplasmosis which usually originates in the lung is well known. However, extrapulmonary hepatic histoplasmosis as a primary manifestation is extremely rare. Case Presentation. We report a rare case of histoplasmosis that presented as persistent fever and abnormal liver function tests in a 66-year-old female with rheumatoid arthritis, receiving infliximab. Conclusion. Emphasizing histoplasmosis as a major cause of acute granulomatous hepatitis and fever of unknown origin in cell mediated immunodeficient population, this case highlights the need for high index of suspicion and the importance of prompt diagnosis since any delay of treatment can be life threatening in this population.

Chikungunya virus (CHIKV) is a mosquito-borne alphavirus which presents with symptoms of fever, rash, arthralgia, and occasional neurologic disease. While outbreaks have been earlier reported from India and other parts of the world, the recent outbreak in India witnessed more than 1000 cases. Various systemic and rarely neurological complications have been reported with CHIKV. We report two cases of Guillain-Barré syndrome (GBS) with CHIKV. GBS is a rare neurological complication which may occur after subsidence of fever and constitutional symptoms by several neurotropic viruses. We describe two cases of severe GBS which presented with rapidly progressive flaccid quadriparesis progressing to difficulty in swallowing and breathing. Both required mechanical ventilation and improved partly with plasmapharesis. The cases emphasize on (1) description of the rare complication in a setting of outbreak with CHIKV, (2) acute axonal as well as demyelinating neuropathy may occur with CHIKV, (3) accurate identification of this entity during outbreaks with dengue, both of which are vector borne and may present with similar complications.

Metastasis to the pituitary gland is extremely rare and is often detected incidentally by symptoms associated with endocrine dysfunction. Breast and lung cancer are the most common primary metastasizing to pituitary gland. Metastasis from hepatocellular carcinoma to the pituitary gland is extremely rare, with only 10 cases having been previously reported. We present here the first case of pituitary metastasis of hepatocellular carcinoma presenting with panhypopituitarism diagnosed by magnetic resonance imaging. We report the case of an 80-year-old Japanese woman who presented with the sudden onset of hypotension and bradycardia after having previously been diagnosed with hepatocellular carcinoma. Based on low levels of pituitary hormones, she was diagnosed with panhypopituitarism caused by metastasis of the hepatocellular carcinoma to the pituitary gland. Magnetic resonance imaging with arterial spin-labeling was effective in the differential diagnosis of the intrasellar tumor. The patient died despite hormone replacement therapy because of hypovolemic shock. Metastasis to the pituitary gland causes various non-specific symptoms, so it is difficult to diagnose. The present case emphasizes the importance of diagnostic imaging in identifying these metastases. Clinicians should consider the possibility of pituitary metastasis in patients with malignant tumors who demonstrate hypopituitarism.

Ectopic thyroid tissue may appear in any location along the trajectory of the thyroglossal duct from the foramen cecum to the mediastinum. Rarely, there is incomplete descent of the gland where the final resting point may be high resulting in sublingual ectopic thyroid tissue. Ectopic thyroid tissue carries a low risk of malignancy. Most recently reported neoplasms in ectopic thyroid tissue have been papillary carcinoma of thyroid. Individual case reports of clear cell type of follicular adenoma within the ectopic thyroid tissue have been described in the literature. We present a rare case of microfollicular follicular adenoma in an ectopic sublingual thyroid tissue presenting as submental swelling in a euthyroid 24-year-old Dravidian woman. Findings in this case emphasize that when confronted with a submental/sublingual mass lesion, the evaluation of thyroid function tests and ultrasonography of the neck should be included in a pre-operative workup.

Schwannomatosis in a patient with a pelvic mass: case report.

PubMed

Harbaugh, Kimberly; Smith, Patricia; Towfighi, Javad

2007-06-15

Schwannomatosis is the most recently recognized form of neurofibromatosis in which patients harbor multiple non-vestibular nerve schwannomas. The diagnosis is contingent on excluding neurofibromatosis Type 2 (NF2), to which it is related. The authors present a case of schwannomatosis diagnosed fortuitously when a preoperative magnetic resonance (MR) image of a pelvic schwannoma was suggestive of a lesion in the lower lumbar canal. Definitive studies confirmed the presence of multiple spinal tumors including a thoracic schwannoma, which was removed during a subsequent procedure. This case emphasizes the need to consider the possibility of multiple tumors in every patient presenting with a schwannoma because the follow-up and genetic counseling are vastly different in those with NF2 and schwannomatosis compared with those harboring sporadic tumors. Details of this case and current considerations in the diagnosis and management of schwannomatosis are discussed.

Collagenous gastritis is a distinctive disorder characterized by thickening of the subepithelial collagen layer in the gastric mucosa. Although this entity was recognized in 1989, its etiology, pathogenesis, and clinicopathologic features remain poorly understood because of its rarity. An unusual case of collagenous gastritis was observed in a 37-year-old man who presented with profound weight loss, a feature that has not previously been emphasized.

In order to develop clinical reasoning, medical students must be able to integrate knowledge across traditional subject boundaries and multiple disciplines. At least two dimensions of integration have been identified: horizontal integration, bringing together different disciplines in considering a topic; and vertical integration, bridging basic science and clinical practice. Much attention has been focused on curriculum overhauls, but our approach is to facilitate horizontal and vertical integration on a smaller scale through an interdisciplinary case study discussion and then to assess its utility. An interdisciplinary case study discussion about a critically ill patient was implemented at the end of an organ system-based, basic sciences module at New York University School of Medicine. Three clinical specialists-a cardiologist, a pulmonologist, and a nephrologist-jointly led a discussion about a complex patient in the intensive care unit with multiple medical problems secondary to septic shock. The discussion emphasized the physiologic underpinnings behind the patient's presentation and the physiologic considerations across the various systems in determining proper treatment. The discussion also highlighted the interdependence between the cardiovascular, respiratory, and renal systems, which were initially presented in separate units. After the session students were given a brief, anonymous three-question free-response questionnaire in which they were asked to evaluate and freely comment on the exercise. Students not only took away physiological principles but also gained an appreciation for various thematic lessons for bringing basic science to the bedside, especially horizontal and vertical integration. The response of the participants was overwhelmingly positive with many indicating that the exercise integrated the material across organ systems, and strengthened their appreciation of the role of physiology in understanding disease presentations and guiding appropriate therapy. Horizontal and vertical integration can be presented effectively through a single-session case study, with complex patient cases involving multiple organ systems providing students opportunities to integrate their knowledge across organ systems while emphasizing the importance of physiology in clinical reasoning. Furthermore, having several clinicians from different specialties discuss the case together can reinforce the matter of integration across multiple organ systems and disciplines in students' minds.

Stridor in paediatric age group is not an uncommon presentation to the ENT emergency. The range of differential diagnosis is vast. The presentation may vary from noisy breathing to severe respiratory distress and apnea. Early and meticulous diagnosis is crucial for the management as the condition may be life threatening. We report a rare case series of 3 infants with Arnold Chiari Malformation who presented to the hospital with stridor and were diagnosed with bilateral vocal cord palsy. These 3 infants had similar underlying neurological condition with hydrocephalus and raised intracranial pressure. Chiari malformation is the one of the most common congenital central nervous system anomaly associated with bilateral vocal cord paralysis. However, the presentation is rare. This article, thus, emphasizes the significance of early diagnosis and immediate management of this condition. PMID:27790480

Severe skin dermatitis, multiple allergies and metabolic wasting (SAM) syndrome is a rare life-threatening inherited condition caused by bi-allelic mutations in DSG1 encoding desmoglein 1. The disease was initially reported to manifest with severe erythroderma, failure to thrive, atopic manifestations, recurrent infections, hypotrichosis and palmoplantar keratoderma. We present 3 new cases of SAM syndrome in 2 families and review the cases published so far. Whole exome and direct sequencing were used to identify SAM syndrome-causing mutations. Consistent with previous data, SAM syndrome was found in all 3 patients to result from homozygous mutations in DSG1 predicted to result in premature termination of translation. In contrast, as compared with patients previously reported, the present cases were found to display a wide range of clinical presentations of variable degrees of severity. The present data emphasizes the fact that SAM syndrome is characterized by extensive phenotypic heterogeneity, suggesting the existence of potent modifier traits.

Feeding a neonate with a complete cleft lip and palate is difficult pursuit due to communication between oral cavity and nasal cavity. A multidisciplinary approach is required to manage the complex problems involved in case of such neonates and their families. Present case is of a 1-day-old neonate having complete bilateral cleft lip and palate for which palatal obturator was constructed. A stepwise simple, easy and uncomplicated procedure for making accurate impressions, maxillary cast and fabrication of palatal obturator in infants with cleft lip and palate has been presented. The objective to present this case report is to emphasize the fact that how these palatal obturators /plates help in feeding, speech/language development, presurgical orthopedics and prevent other associated otorhinolaryngeal problems.

Rhodotorula is emerging as an important cause of nosocomial and opportunistic infections. We present two cases of Rhodotorula mucilaginosa fungemia diagnosed at our hospital during the last decade. The first case was of a term neonate who presented congenital heart disease (interventricular communication) and body dysmorphic disorder. He was admitted for respiratory failure and sepsis. The second case involved in a 33-year-old woman that had Hodgkinien lymphoma associated to tuberculosis. Identification was performed using commercial systems and confirmed by PCR sequencing of internal transcribed spacer, ITS1 and ITS2 regions of rDNA. Antifungal susceptibility tested by sensititre yeast revealed susceptibility to amphotericin B and resistance to fluconazole for the two strains. These cases emphasize the emerging importance of Rhodotorula sp. as a pathogen and it must be considered a potential pathogen in patients with immunosupression and with central venous catheters. Correct identification is mandatory for appropriate management, as Rhodotorula spp. are resistant to antifungal agents, such as fluconazole. Copyright © 2016 Elsevier Masson SAS.

The syndrome of pregnancy-associated osteoporosis (PAO) is a rare disorder which occurs either in late pregnancy or early post-partum period leading to fragility fracture(s), most commonly in the vertebral bodies. We presented two cases with PAO who had compression fractures at multiple levels involving five vertebrae in one case and 10 vertebrae in the other. Their spinal bone mineral density values were below -2.5 standard deviations. Anti-osteoporotic treatments with nasal calcitonin 400 IU/day, vitamin D 300.000 IU single dose, calcium 1000 mg/day, vitamin D 880 IU/day were initiated. In one case, kyphoplasty was performed by a spinal surgeon. In addition to a thoracolumbosacral orthosis, a rehabilitation program including muscle strengthening, range of motion, relaxation and weight-bearing exercises was started for both cases. These cases emphasize that all pregnant women with complaints of back/lumbar pain should be carefully evaluated. © 2013 The Authors.

2012-01-01

This report presents two cases of human fascioliasis from different states in India. Although only few cases of human fascioliasis have been reported from India previously, both these cases were encountered within a span of three months at this tertiary care centre. Case 1 had significant symptoms with episodes of fever, abdominal pain and eosiniphilia and underwent multiple diagnostic procedures before the correct diagnosis was reached. Case 2, who had few symptoms, had fascioliasis diagnosed with minimal evaluation. These different presentations seen at two ends of the clinical spectrum of disease along with findings of peripheral eosinophilia, and radiological findings led to a presumptive diagnosis that was then confirmed by microscopic examination of bile. Morphometric analysis of ova from these cases was suggestive of infestation with F. gigantica or a F. gigantica-like hybrid. Both patients were treated with triclabendazole which was imported from Geneva. The need to be aware of the possibility of occurrence of this disease and the inclusion of drugs used for treating the disease, in the Indian drug list, should be emphasized.

Renal oncocytoma is a neoplasm which rarely occurs in patients with solitary kidney, the other being absent because of a previous nephrectomy performed for renal cancer. We present two case reports and a literature review. We have studied some important problems such as the histogenesis, the potential for malignancy, the diagnosis, the treatment and the follow up. The high incidence of coexistence of renal oncocytoma and renal cell carcinoma has important clinical implications. We would like to emphasize the importance of preoperatory FNAB, nephron sparing surgery and very careful follow up.

Two cases of mediastinal emphysema occurring in healthy individuals climbing to the summit of Mount Rainier (4,393 m.) are described. In both, the condition was probably attributable to a voluntary, forced pressure breathing technique--a modified Valsalva maneuver. The various circumstances in which mediastinal emphysema may occur are discussed, along with its possible serious complication of cardiorespiratory compromise. The means of diagnosis are presented, emphasizing that cases in which the important finding of subcutaneous emphysema is absent may be those in which the danger is greatest. Therapeutic measures that occasionally may be necessary are outlined, though the condition is usually a benign one that subsides without specific treatment.

Excessive consumption of cola-based drinks has been associated with dental enamel erosion, obesity, and diabetes. There are very few published cases depicting the correlation between cola drinks and hypokalemic manifestations. In our patient an extensive workup was performed, and common causes were ruled out before making the diagnosis of cola-induced hypokalemia. Improvement in the patient's symptoms and electrolyte levels after reducing the consumption of cola-based drinks further confirmed our diagnosis. This case also emphasizes the importance of obtaining a detailed history and consideration of broad differential diagnoses in identifying uncommon but reversible etiologies. © 2014 Marshfield Clinic.

Ramsay Hunt syndrome (RHS) is a disorder characterized by herpetic eruptions on the auricle, facial paralysis, and vestibulocochlear dysfunction and is attributed to varicella zoster virus (VZV) infection in the geniculate ganglion. Although it is a common cause of acute peripheral facial paralysis, children are not usually affected. The diagnosis is based on history and physical findings. Treatment of RHS uses a combination of high-dose corticosteroids and acyclovir. This paper presents three cases diagnosed as RHS in the pediatric age group in association with the literature review. The aim of this paper is to emphasize the importance of careful examination and early initiation of therapy in suspected cases of RHS. PMID:26435868

1998-12-01

A Fortran 77 program, specsim, is presented for conditional spectral simulation in 3D domains. The traditional Fourier integral method allows generating random fields with a given covariance spectrum. Conditioning to local data is achieved by an iterative identification of the conditional phase information.

A comparison with the traditional sequential Gaussian simulation algorithm emphasizes the advantages and drawbacks of the proposed algorithm.

Automating the Generation of Heterogeneous Aviation Safety Cases

NASA Technical Reports Server (NTRS)

Denney, Ewen W.; Pai, Ganesh J.; Pohl, Josef M.

2012-01-01

A safety case is a structured argument, supported by a body of evidence, which provides a convincing and valid justification that a system is acceptably safe for a given application in a given operating environment. This report describes the development of a fragment of a preliminary safety case for the Swift Unmanned Aircraft System. The construction of the safety case fragment consists of two parts: a manually constructed system-level case, and an automatically constructed lower-level case, generated from formal proof of safety-relevant correctness properties. We provide a detailed discussion of the safety considerations for the target system, emphasizing the heterogeneity of sources of safety-relevant information, and use a hazard analysis to derive safety requirements, including formal requirements. We evaluate the safety case using three classes of metrics for measuring degrees of coverage, automation, and understandability. We then present our preliminary conclusions and make suggestions for future work.

We present a rare case of malignant pheochromocytoma with thoracic metastases during pregnancy that presented with symptoms of myelopathy and was treated with circumferential decompression, stabilization, and radiation. The management of this unique case is not well documented. The clinical manifestations, imaging results, pathological characteristics, treatment and prognosis of the case were analyzed. A 26-year-old pregnant woman with a history of paroxysmal hypertension during the second trimester presented with lower extremity weakness, numbness, urinary incontinence, and back pain. Imaging studies revealed a right adrenal pheochromocytoma, multiple metastases at T8, T11, T12, and the pelvis girdle causing significant multilevel cord compression and significant osteolytic lesions at T11 and T12. We believe this is the first reported case of metastatic pheochromocytoma of the thoracic spine presenting with symptoms of myelopathy during pregnancy. A healthy neonate was delivered by emergency caesarean section at 34 weeks. Subsequently, the patient underwent a circumferential spinal cord decompression and a stabilization procedure. The patient's neurological deficits improved significantly after the surgery, and the postoperative period was uneventful at the 6-month follow-up visit. This article emphasizes that metastatic pheochromocytoma of the spine, although rare, should be part of the differential when a patient presents with elevated blood pressure, weakness, and urinary incontinence.

Varicella results from a primary infection with the varicella virus while herpes zoster is caused by a reactivation of a latent infection. Dissemination of herpes zoster is uncommon in immunocompetent individuals. Reports of disseminated herpes zoster in children are even less common than in adults. An unusual case of disseminated herpes zoster ophthalmicus in an 8-year old immunocompetent black boy is presented. He had a previous primary Varicella zoster virus infection at three years of age. In the current report, he presented during an on-going chicken pox outbreak and survived with no significant complications. A breakthrough varicella virus re-infection or a reactivation is possible, both of which could present as zoster. This case emphasizes the need for prevention of varicella virus infection through universal childhood immunization and effective infection control strategies in health care settings. PMID:24765504

2013-07-01

Men and women have been seeking professional assistance to help control hypersexual urges and behaviors since the nineteenth century. Despite that the literature emphasizes that cases of hypersexuality are highly diverse with regard to clinical presentation and comorbid features, the major models for understanding and treating hypersexuality employ a "one size fits all" approach. That is, rather than identify which problematic behaviors might respond best to which interventions, existing approaches presume or assert without evidence that all cases of hypersexuality (however termed or defined) represent the same underlying problem and merit the same approach to intervention. The present article instead provides a typology of hypersexuality referrals that links individual clinical profiles or symptom clusters to individual treatment suggestions. Case vignettes are provided to illustrate the most common profiles of hypersexuality referral that presented to a large, hospital-based sexual behaviors clinic, including: (1) Paraphilic Hypersexuality, (2) Avoidant Masturbation, (3) Chronic Adultery, (4) Sexual Guilt, (5) the Designated Patient, and (6) better accounted for as a symptom of another condition.

Penis deformity after intra-urethral liquid paraffin administration in a young male: a case report

Kokkonouzis, Ioannis; Antoniou, Georgios; Droulias, Athanasios

2008-01-01

Background Self-induced injections of liquid substances mainly for penis enlargement is a well-documented but still rather uncommon practice in the western world. Case presentation Herein we present the case of a 30-year-old male who self-inflicted, twice in a six-month-period, intra-urethral liquid paraffin and tied up his penis with a cord in order to achieve both enlargement and elongation. He arrived in our emergency department suffering from suprapubic pain; physical examination revealed a rather unique deformity of the penis. He finally refused any treatment and absconded. Conclusion Side effects after paraffin administration are various and sometimes severe. Most of the times surgical treatment is needed and radical excision together with follow-up seems the best modality. Such practices emphasize on the public's misbelieves and that some aspects of sexual medicine are yet covered with the veil of misconception. PMID:18840268

Model-Invariant Hybrid Computations of Separated Flows for RCA Standard Test Cases

NASA Technical Reports Server (NTRS)

Woodruff, Stephen

2016-01-01

NASA's Revolutionary Computational Aerosciences (RCA) subproject has identified several smooth-body separated flows as standard test cases to emphasize the challenge these flows present for computational methods and their importance to the aerospace community. Results of computations of two of these test cases, the NASA hump and the FAITH experiment, are presented. The computations were performed with the model-invariant hybrid LES-RANS formulation, implemented in the NASA code VULCAN-CFD. The model- invariant formulation employs gradual LES-RANS transitions and compensation for model variation to provide more accurate and efficient hybrid computations. Comparisons revealed that the LES-RANS transitions employed in these computations were sufficiently gradual that the compensating terms were unnecessary. Agreement with experiment was achieved only after reducing the turbulent viscosity to mitigate the effect of numerical dissipation. The stream-wise evolution of peak Reynolds shear stress was employed as a measure of turbulence dynamics in separated flows useful for evaluating computations.

Three cases are presented which emphasize the importance of hyponatraemia as a cause of grand mal seizures. The combination of hydrochlorothiazide and amiloride appears to increase the risk of hyponatraemia. We discuss the aetiology and treatment of hyponatraemia and review the necessity for such combination therapy. We recommend caution in prescribing diuretics and preparations such as Moduretic should be used only in those few patients shown to need potassium supplementation. PMID:2506346

Vázquez, I; Agüera-Ortiz, L F

2002-01-01

Ginseng root extract is a widely used herbal product not devoid of side effects. This report describes the development of manic symptoms after ginseng consumption in a patient with affective disorder. Other potentially harmful side effects of ginseng are also reviewed. A single case report. A 56-year-old woman with previous affective disorder presented a manic episode during ginseng intake. Symptoms disappeared rapidly with low doses of neuroleptics and benzodiazepines after ginseng suppression. Ginseng may produce manic symptoms. A special risk situation seems to be affective patients under antidepressant medication. The case emphasizes the lack of harmlessness of herbal products. Patients should be routinely asked about the use of herbal products and diet supplements.

2012-04-01

Subdural empyema is a known disease entity; however, calcified subdural empyema is uncommon. The authors present a case of an 11-year-old boy in whom there was diagnosed a chronic calcified subdural empyema 10 years after an attack of meningitis. The patient had suffered from generalized tonic clonic seizures occurring 2-6 times in a month. A large fronto-temporo-parietal craniotomy was carried out and the subdural empyema filled with numerous uncharacteristic tissue fragments with thick pus together with the partially calcified and ossified capsule was removed. The empyema mass was found to be sterile for bacteria. After the operation, no epileptic seizure occurred and the boy is on sodium valporate. We must emphasize the unusual occurrence of the chronic subdural empyema presenting with calcification-ossification and large size as observed in our case.

Simultaneous presentation of acute disseminated encephalomyelitis (ADEM) and systemic lupus erythematosus (SLE) after enteroviral infection: can ADEM present as the first manifestation of SLE?

Central Nervous System (CNS) involvement of Systemic Lupus Erythematosus (SLE) includes a broad range of neuropsychiatric syndromes. Acute Disseminated Encephalomyelitis (ADEM) is a demyelinating CNS disorder characterized by encephalopathy and multifocal lesions predominantly involving the white matter on brain magnetic resonance imaging. ADEM associated with SLE has been only rarely reported. We report an unusual case of a 17-year-old girl who developed ADEM after enteroviral infection as the first manifestation of SLE. The authors emphasize that the patient's illness was preceded by enteroviral infection and that ADEM occurred before any other symptoms of SLE, which makes this case unique. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Autoerythrocyte sensitization (AES) is a rare syndrome particularly among males. A young male with typical AES is herewith described. We review all seven published cases of AES in men for which details are available and compare the age of onset, somatic manifestations, associated diseases and psychiatric disturbances between the sexes. We emphasize that the criteria essential for a diagnosis of AES should include typical clinical presentation, longstanding clinical history and a positive skin test with the patient's blood. Because of the rarity of AES there is a lack of awareness regarding it among many doctors. Images Figure 1 PMID:4059144

Fetal intestinal volvulus is a rare but serious finding with a high risk of potential life threatening fetal complications. Delay in diagnosis or treatment can increase mortality and morbidity. We report a case of mild fetal bowel dilatation at 30 weeks of gestation and intestinal volvulus presented by the 'whirl-sign', intestinal perforation and meconium peritonitis with fetal ascites and polyhydramnios at 33 weeks of gestation. This case emphasizes the role of examination of the bowel in third trimester ultrasound and the importance of quick decision to delivery and interdisciplinary perinatal management at suspected fetal volvulus with bowel necrosis and intraabdominal bleeding.

Perioperative derangements of fluid and electrolyte homeostasis are rare complications in healthy children. Nonetheless, early diagnosis and treatment are mandatory to avoid a potentially life-threatening situation. However, the variety of underlying pathologies may prove to make accurate diagnosis challenging. This case report presents the management of an unexpected occurrence of a perioperative partial diabetes insipidus with massive fluid loss. Diagnostic and therapeutic procedures are discussed in the context of laboratory findings, and an overview of the existing literature is given. Finally, we emphasize that a multidisciplinary approach is most appropriate for diagnosis, accurate treatment, and follow-up of the patient.

Psychosis, impulse control disorders (e.g., pathological gambling and hypersexuality) and repetitive behaviors such as punding are known psychiatric complications of Parkinson's disease (PD). Impulsive, compulsive and repetitive behaviors are strongly associated with dopamine-replacement therapy. We present the case of a 58-year-old man with PD and a myriad of psychiatric symptoms. Concurrent psychosis, punding and pathological gambling developed more than six years after the introduction of pramipexole and ceased shortly after the addition of quetiapine and discontinuation of pramipexole. This report emphasizes the importance of monitoring for a wide array of psychiatric symptoms in patients on dopamine replacement therapy.

Cognitive-Behavioral Treatment of Hoarding in Youth: A Case Illustration.

PubMed

McKay, Dean

2016-11-01

Hoarding in children is associated with more severe ancillary psychopathology, and has poor treatment outcome. At present, there are no empirically established procedures for treating hoarding in youth. The present case illustration is of a 10-year old child ("Grace") who presented for treatment with significant hoarding related to academic concerns and additional unrelated symptoms of obsessive-compulsive disorder (OCD). Grace was treated with cognitive behavior therapy (CBT) primarily comprising exposure with response prevention, behavioral experiments, and cognitive therapy, along with a program of reinforcement delivered by her parents to maintain her motivation for therapy. After 23 sessions and one booster session, Grace's symptoms improved significantly, with gains maintained at 1-year follow-up. In addition to the benefits of the specific interventions chosen, the role of therapist-patient/parent alliance as a contributory factor for good outcome is emphasized. As hoarding is underinvestigated in youth, suggestions for further investigation are offered. © 2016 Wiley Periodicals, Inc.

Atypical presentation of paroxysmal nocturnal hemoglobinuria treated by eculizumab

2017-01-01

Abstract Rationale: Paroxysmal nocturnal hemoglobinuria (PNH) is a nonmalignant acquired hematopoietic stem cell disease, which can be revealed by hemolytic anemia, thromboembolism, or bonemarrow failure. Thrombosis can occur at any site, but coronary thrombosis is extremely rare. Controlled trials have demonstrated that eculizimab, an inhibitor of the terminal complement cascade, was able to reduce both hemolysis and thrombosis, but its efficacy in cases of PNH with coronary thrombosis is unknown. Patient concerns and diagnoses: We report herein the unusual case of a 73-year-old patient presenting with recurrent coronary syndromes without associated stenosis, fever, marked inflammatory syndrome, and anemia, leading to a delayed diagnosis of PNH. Intervention and outcomes: Eculizumab allowed the resolution of fever and inflammation, and prevented further thromboembolism. Lessons: This case emphasizes the importance of performing aflow cytometry test for PNH in front of unusual or unexplained recurrent thromboses. Thromboses, as observed in our case, may be associated with fever and marked inflammation. This case also provides useful information on eculizumab ability to prevent further thromboembolism in PNH patients with a medical history of arterial thrombosis. PMID:28328837

Mycosis fungoides is a cutaneous T-cell lymphoma with a high risk for developing secondary malignancies, especially B-cell lymphoproliferative disorders. About 40 cases of Hodgkin's lymphoma associated with mycosis fungoides have been reported in literature till date. We report a case of a 35-year-old gentleman who presented with intensely itchy reddish lesions all over the body. Multiple skin biopsies taken from the lesions on scalp and back confirmed the clinical diagnosis of mycosis fungoides. While on treatment, he presented with multiple bilateral cervical, axillary and inguinal lymphadenopathy 9 years after the primary diagnosis of mycosis fungoides. Excision biopsy of a cervical lymph node revealed partial effacement of architecture by a tumor comprising polymorphous background. Histopathology and immunohistochemistry revealed a diagnosis of Hodgkin's lymphoma - nodular sclerosis subtype. The patient was started on chemotherapy for stage IV Hodgkin's lymphoma. Our case emphasizes the importance of keeping secondary Hodgkin's lymphoma in mind while dealing with a patient of mycosis fungoides. Our case immunohistochemically supports the distinct etiopathogenesis of Epstein-Barr virus-negative Hodgkin's lymphoma vis-à-vis cutaneous mycosis fungoides.

Enterobius vermicularis is the most common helminthic infection in the US. It is usually considered an innocuous parasite that at the most causes perianal itching. We report a case of an 84-year-old female patient from an assisted living facility who presented with symptoms of colitis for 2 months. On detailed history and exam, she was found to have E. vermicularis infection. All her symptoms resolved dramatically within 2 days after a single dose of albendazole. We want to emphasize the importance of including parasitic infections such as E. vermicularis in the differential diagnoses of patients presenting with symptoms of colitis.

2011-01-01

Oral paracoccidioidomycosis and oral squamous cell carcinoma may occur in the same patient. As both lesions may present similar clinical and histopathological features, the diagnosis is sometimes challenging. This paper describes the case of a 54-year-old male who was a farm worker and heavy alcohol and tobacco user. He developed paracoccidioidomycosis and two lesions of squamous cell carcinoma in the oral cavity. During the follow-up, the patient presented enlargement of the submandibular lymph nodes, which was thought to be regional metastasis but was diagnosed as paracoccidioidomycosis. Therefore, the significance of this association is emphasized and discussed.

Three-dimensional multigrid Navier-Stokes computations for turbomachinery applications

Subramanian, S. V.

1989-07-01

The fully three-dimensional, time-dependent compressible Navier-Stokes equations in cylindrical coordinates are presently used, in conjunction with the multistage Runge-Kutta numerical integration scheme for solution of the governing flow equations, to simulate complex flowfields within turbomechanical components whose pertinent effects encompass those of viscosity, compressibility, blade rotation, and tip clearance. Computed results are presented for selected cascades, emphasizing the code's capabilities in the accurate prediction of such features as airfoil loadings, exit flow angles, shocks, and secondary flows. Computations for several test cases have been performed on a Cray-YMP, using nearly 90,000 grid points.

Allergic sinusitis and severe asthma caused by occupational exposure to locust bean gum: Case report

Hawley, Brie; Cummings, Kristin J.; Mohammed, Mohammed; Dimmock, Anne E.; Bascom, Rebecca

2017-01-01

We present a case that highlights the difficulties with diagnosis and the dangers of occupational allergic sinusitis and asthma left unrecognized. We describe the case history of a man who experienced work-related symptoms 1 year after beginning work as a cheesemaker at a creamery, and whose respiratory symptoms progressively worsened over 16 years before an occupational cause of his asthma was identified. His initial discrete episodes of sinusitis and acute bronchitis evolved into persistent asthma of increasing severity with exacerbations requiring repeated emergency room treatment. The case described in our report emphasizes the importance of clinician diagnosis of OA, and subsequent removal from exposure, such that asthma severity does not progress to near-fatal or fatal asthma in the sensitized worker. As demonstrated by this case report, identification of an occupational cause of asthma relies on a high degree of suspicion and excellent detective work by the clinician. PMID:28497854

2014-12-01

Persons suffering from gender identity disorder (GID) are often severely marginalized in India and mostly live outside the society as a part of a minority community called the Hijras. Although substance abuse is considered a way of life in them, such patients rarely seek treatment because of the stigma and fear of discrimination. We report a case of GID presenting to tertiary care centre for treatment of multiple substance use dependence (SUD). The case is the first to highlight the use and dependence of multiple substances in the Hijra community of India. Further, the case emphasizes that SUD treatment might be a worthwhile intervention to bring such marginalized population under treatment, when further complicated issues on gender identity can be addressed.

Through the case presentation of a diagnostically and therapeutically interesting gender dysphoric individual, the authors wish to address diagnostic problems associated with this controversial category, illustrate dilemmas and emphasize the importance of diagnostic procedures in differentiating between primary transsexualism and other transgender states. Many questions have been triggered by this case, mainly about whether this patient should be classified as a paraphilia (transvestite, transvestite with transsexual trend), primary transsexualism or autogynephilia and about the most adequate treatment (e.g., sex-reassignment surgery, hormone therapy as a way of partial feminisation or exclusively psychotherapy). The issue of reconstructive surgery, i.e. its justification in the case of this particular condition is specifically discussed. Before any decision is made, both medical but also ethical consequences of the treatment choice need to be considered (e.g., the client is the father of two underage children).

Gemination or fusion is a rare occurrence in the mandibular posterior teeth. The aim of this article is to describe the problems encountered and the strategy employed in treating such cases. A 34 years old patient came with the complaint of spontaneous and radiating pain in the right mandibular posterior region. The tooth in concern was an anomalous 'double' second mandibular molar diagnosed as having necrotic pulp with chronic apical abscess of endodontic origin. The present case emphasizes the importance of identifying anatomical anomalies during treatment of fused teeth with supernumerary tooth, and the need for the use of advanced imaging modalities like CBCT which is a critical aid in the diagnosis of such cases. Fused teeth can be managed quite efficiently by an overall combined treatment including both endodontic and periodontal therapy.

NON-SURGICAL TREATMENT OF A PROFESSIONAL HOCKEY PLAYER WITH THE SIGNS AND SYMPTOMS OF SPORTS HERNIA: A CASE REPORT

PubMed Central

Woodward, J. Scott; Parker, Andrew; MacDonald, Robert M.

2012-01-01

Study Design: Case Report Background: Injury or weakness of lower abdominal attachments and the posterior inguinal wall can be symptoms of a “sports hernia” and an underlying source of groin pain. Although several authors note conservative treatment as the initial step in the management of this condition, very little has been written on the specific description of non-surgical measures. Most published articles favoring operative care describe poor results related to conservative management; however they fail to report what treatment techniques comprise non-operative management. Case Presentation: The subject of this case report is a professional ice hockey player who sustained an abdominal injury in a game, which was diagnosed as a sports hernia. Following the injury, structured conservative treatment emphasized core control and stability with progressive peripheral demand challenges. Intrinsic core control emphasis continued throughout the treatment progression and during the functional training prior to return to sport. Outcome: The player completed his recovery with return to full competition seven weeks post injury, and continues to compete in the NHL seven years later. Discussion: Surgical intervention has been shown to be effective in the treatment of the “sports hernia.” However it is the authors' opinion that conservative care emphasizing evaluation of intrinsic core muscular deficits and rehabilitation directed at addressing these deficits is an appropriate option, and should be considered prior to surgical intervention.

The purpose is to create more awareness as well as emphasize the risk of permanent nerve injury as a complication of elbow arthroscopy. Patients who underwent elbow arthroscopy complicated by permanent nerve injury were retrospectively collected. Patients were collected using two strategies: (1) by word-of-mouth throughout the Dutch Society of Shoulder and Elbow Surgery, and the Leiden University Nerve Centre, and (2) approaching two medical liability insurance companies. Medical records were reviewed to determine patient characteristics, disease history and postoperative course. Surgical records were reviewed to determine surgical details. A total of eight patients were collected, four men and four women, ageing 21-54 years. In five out of eight patients (62.5%), the ulnar nerve was affected; in the remaining three patients (37.5%), the radial nerve was involved. Possible causes for nerve injury varied among patients, such as portal placement and the use of motorized instruments. A case series on permanent nerve injury as a complication of elbow arthroscopy is presented. Reporting on this sequel in the literature is little, however, its risk is not to be underestimated. This study emphasizes that permanent nerve injury is a complication of elbow arthroscopy, concurrently increasing awareness and thereby possibly aiding to prevention. IV, case series.

A 22-year-old male presented with reddish discoloration of the vest following perspiration for 6 months. He was a habituated consumer of cranberry juice. The peak absorption on spectrophotometric analysis of the extracted sweat coincided approximately with the peak absorption of diluted distillate of the juice. A diagnosis of eccrine chromhidrosis, probably due to the coloring agents in the juice, was considered. This rare case report emphasizes the possible side effect of the various coloring agents used as food additives. PMID:29263551

We report on a liveborn male infant with mosaic tetraploidy who presented with multiple congenital anomalies including features of the DiGeorge anomaly (type I truncus arteriosus with other cardiovascular malformations, thymic hypoplasia, hypocalcemia). No structural chromosome aberrations, namely of chromosome 22, were detected. These findings contribute to the variability of symptoms of the polyploid phenotype. Additionally, the cytogenetic studies in our case emphasize the necessity of investigating fibroblasts in order to evaluate the relevant proportion of aberrant cells in mosaicism.

Recent developments in chaotic dynamics

Ott, E.

1994-02-01

Before the relatively recent wide acceptance of the existence of chaotic dynamics, many physicists and engineers were under the impression that simple systems could necessarily only display simple solutions. This feeling had been unintentionally reinforced by conventional college courses which emphasize linear dynamics (partly because that is the only case with nice general solutions). More recently, physical experiments and numerical examples have abundantly demonstrated how wrong this feeling is. A brief review of chaotic dynamics is presented. Topics discussed include basic concepts, recent developments, and applications.

Nelson, M S; Chisolm, J J

1986-06-01

We recently saw a 12-year-old black boy with known sickle cell disease who had been seen many times for abdominal pain thought to be secondary to a vasoocclusive crisis. The patient eventually was admitted, after a seizure and the onset of obtundation. The etiology of his acute encephalopathy remained unclear until bone films of his knees fortuitously revealed "lead lines." The patient was treated and did well subsequently. This case emphasizes the importance of considering other diagnoses when a sickle cell patient presents with a crisis.

Pearls and pitfalls: Autoimmune lymphoproliferative syndrome and autoimmune lymphoproliferative syndrome-like disease.

A case of autoimmune lymphoproliferative syndrome (ALPS) was presented, followed by a discussion of the clinical characteristics, pathophysiology, diagnosis, and management of this disease. Clinical pearls and pitfalls are emphasized for the use of the practicing allergist and the fellow in-training. The diagnosis of ALPS was guided by published criteria. A careful history and workup were needed to exclude other possible etiologies for the patient's symptoms and physical findings. ALPS often carries significant morbidity and is best managed through a multidisciplinary approach.

Two adolescent native Canadians who presented with peripheral neuropathy secondary to the abuse of volatile hydrocarbons are described. They were initially thought to have been sniffing leaded gasoline fumes, but public health investigation revealed that they had been sniffing naphtha fumes. Naphtha contains a significant amount of n-hexane, a known inducer of neuropathy. Nerve conduction studies and nerve biopsy confirmed the diagnosis of naphtha abuse. These cases emphasize the need to specifically identify the formulation of hydrocarbons being abused. PMID:6093978

Background: Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis. Genital TB (GTB) is a form of extrapulmonary TB that occurs more frequently in women, in whom it classically presents in association with menstrual irregularity, pregnancy loss and short and long-term sequelae especially infertility in infected women. Patients with GTB are usually young women diagnosed during workup for infertility. GTB is rare in postmenopausal women and responsible for only approximately 1% of postmenopausal bleeding. In this study, we aimed to evaluate the laboratory, clinical and demographic characteristics of female GTB cases. Case: We presented four female GTB cases with distinct clinical symptoms. All patients have no history of TB, and no acid-fast bacilli were seen in smears prepared from the clinical materials of the patients. Histopathological examinations revealed granulomatous inflammation in all patients. Conclusion: In the light of the clinical features of these cases we aimed to emphasize that, female GTB must be taken into account in the patients with different clinical symptoms like postmenopausal bleeding, menometrorrhagia, infertility, and menstrual irregularities. We believe that these symptoms will be helpful for the diagnosis and treatment of female GTB. PMID:29675489

The use of clinostats and centrifuges to explore the hypogravity range between zero and 1 g is described. Different types of clinostat configurations and clinostat-centrifuge combinations are compared. Some examples selected from the literature and current research in gravitational physiology are presented to show plant responses in the simulated hypogravity region of the g-parameter (0 is greater than g is greater than 1). The validation of clinostat simulation is discussed. Examples in which flight data can be compared to clinostat data are presented. The data from 3 different laboratories using 3 different plant species indicate that clinostat simulation in some cases were qualitatively similar to flight data, but that in all cases were quantitatively different. The need to conduct additional tests in weightlessness is emphasized.

Sandfly fever, sometimes known as pappataci fever or Phlebotomus fever, is a vector transmitted viral illness with a history of affecting naïve military formations that travel through or fight in areas in which the infection is endemic. We present a series of 4 hospitalized cases of sandfly fever (2 presumptive, 2 laboratory confirmed) that were admitted to a Role 3 hospital in Afghanistan for evaluation and treatment following medical evacuation from a forward area for marked fevers and malaise. Laboratory evaluation of these cases was significant for leukopenia and thrombocytopenia, consistent with historical descriptions of sandfly fever. In the correct geographic and clinical setting, the finding of mild leukopenia among a cluster of febrile patients should prompt the clinician to at least consider a diagnosis of sandfly fever. A cluster investigation conducted by preventive medicine personnel identified numerous other presumed cases of sandfly fever in this forward special operations camp. Response efforts emphasized enforcement of standard vector-borne disease control measures by operational leadership in order to limit effect on tactical operations. We review historical instances of sandfly fever affecting military operations, and present a review of clinical presentation, transmission, management, and prevention.

Polyglandular autoimmune syndrome type II (PGA-II) is a rare immunoendocrinopathy syndrome characterized by the occurrence of autoimmune Addison disease along with diabetes mellitus type 1 and/or autoimmune thyroid disease. Here, we report the case of a 23-year-old female with PGA-II who was followed up at the dermatology and endocrinology clinics of the Universidade Federal do Triângulo Mineiro, located in the state of Minas Gerais, Brazil. First, the patient presented diffuse skin hyperpigmentation, vitiligo; and in sequence, due to vomiting, appetite and weight loss, hypoglycemia, amenorrhea, and galactorrhea, the patient was then diagnosed with PGA-II. The patient also presented intense hyperprolactinemia due to primary hypothyroidism. The late diagnosis of PGA-II is frequent because the disorder is uncommon and has non-specific clinical manifestations. This report emphasizes the significance of a timely diagnosis and appropriate treatment to reduce morbidity and mortality associated with these diseases, especially Addison disease. The present study reports a rare case of a patient with PGA-II with primary amenorrhea associated with hyperprolactinemia. Thieme Revinter Publicações Ltda Rio de Janeiro, Brazil.

Idiopathic granulomatous mastitis: a mimicking disease in a pregnant woman: a case report

PubMed Central

2013-01-01

Background Idiopathic granulomatous mastitis is a rare, benign, inflammatory chronic condition of unclear etiology. This case is reported because it illustrates how idiopathic granulomatous mastitis can mimic other diseases, making it difficult to associate the presenting symptoms and the correct diagnosis; This disease is a challenge for clinicians to diagnose, manage and avoid iatrogenic complications, and requires consultation with experts in several specialties. Case presentation The patient was 30 years old, South-American, eleven weeks pregnant, and with an apparent infectious mastitis. She presented with progressive worsening of her breast symptoms and multiple negative laboratory tests. She suffered different side effects from several prescribed treatments and endured a prolonged recovery. The article emphasizes the need for ruling out common pathologies to arrive at the correct diagnosis such as bacterial and fungal infections; granulomatous conditions like tuberculosis and sarcoidosis; and inflammatory breast carcinoma. It also describes frequently used pharmacological and supplementary forms of treatment for patients with this condition. Conclusion Idiopathic granulomatous mastitis is a rare unusual condition of unknown etiology. Pathological confirmation is required for its diagnosis and optimal management is still unclear. The presentation and management of this case is intended to advance its awareness to physicians from different specialties. PMID:23497626

Central neuraxial anaesthesia presenting with spinal myoclonus in the perioperative period: a case series

PubMed Central

2009-01-01

Introduction Perioperative spinal myoclonus is extremely rare. Many anaesthetists and perioperative practitioners may not diagnose or manage this complication appropriately when it occurs. This case report of unusual acute spinal myoclonus following regional anaesthesia highlights certain aspects of this rare complication that have not previously been published. Case presentations A series of four consecutive patients who developed acute lower-limb myoclonus following spinal or epidural anaesthesia are described. The case series occurred at three different hospitals and involved four anaesthetists over a 3-year period. Two Caucasian men, aged 90-years-old and 67-years-old, manifested unilateral myoclonus. Two Caucasian women, aged 64-years-old and 53-years-old, developed bilateral myoclonus. Myoclonus was self-limiting in one patient, treated with further regional anaesthesia in one patient and treated with intravenous midazolam in two patients. The overall outcome was good in all patients, with no recurrence or sequelae in any of the patients. Conclusion This case series emphasizes that spinal myoclonus following regional anaesthesia is rare, has diverse pathophysiology and can have diverse presentations. The treatment of perioperative spinal myoclonus should be directed at the aetiology. Anaesthetists and perioperative practitioners who are unfamiliar with this rare complication should be reassured that it may be treated successfully with midazolam. PMID:19830168

An interesting case report of vertebral artery dissection following polytrauma.

PubMed

Acharya, Vikas; Chandrasekaran, Suresh; Nair, Sujit

2016-01-01

The authors present an interesting case of a 19-year-old male who presented as a polytrauma patient following a fall from a height. He was initially managed on the intensive care unit with intracranial pressure bolt monitoring after being intubated and sedated and having his other traumatic injuries stabilized. Upon attempting to wean sedation and extubation a repeat CT scan of the head was undertaken and showed a new area suggested of cerebral infarction, this was a new finding. Further imaging found that he had a cervical vertebral artery dissection following this polytrauma mode of injury. The incidence of vertebral artery dissection following generalized or local trauma is rising but routine imaging/screening in these patients is not undertaken. Our report displays select images related to this case report and emphasizes the consideration of routine imaging in head and neck traumatic injuries to diagnose internal carotid and/or vertebral artery dissections much earlier.

1996-01-01

We report a case of a 65-year-old woman who nine years previously had undergone total abdominal hysterectomy and bilateral salpingoophorectomy for a large ovarian cyst. During surgery the cyst had ruptured and some mucinous material had been spilled intraabdominally. Histopathological studies demonstrated the cyst to be a mucinous adenocarcinoma of low malignant potential. Appendectomy had also been performed due to an enlarged appendix, which proved to be a mucocoele. The patient had been lost to subsequent follow-up. Her current presenting symptom was a giant inguino-labial hernia of 25 cm diameter with two small skin perforations leaking a gelatinous discharge. Subsequent laparotomy and inguinal exploration have disclosed herniated small intestine with an attached metastatic multicystic mucinous adenocarcinoma. This case represents a case of borderline mucinous adeno-carcinoma-pseudomyxoma peritonei recurring in a unique pattern as a huge inguino-labial hernia, and serves to emphasize the possible consequences of spillage of ovarian cyst contents during surgery.

Paroxysmal supraventricular tachycardia is a common dysrhythmia that occurs at all ages. Its management is determined by presenting symptoms and previous history of the patient. Patients present with a continuum of symptoms ranging from palpitations to syncope. The incidence of supraventricular tachycardia increases with age. To discuss the etiology, precipitating factors, and acute management of supraventricular tachycardia; and to discuss nodal reentry circuits and representative electrocardiographic findings. We present the case of an 84-year-old man with gallstone pancreatitis, choledolcholithiasis, and cholecystitis complicated by paroxysmal supraventricular tachycardia. We review this dysrhythmia, emphasizing its significance in elderly patients. Supraventricular tachycardia is a common dysrhythmia that can result in syncope or myocardial infarction. We present a case of an elderly man with new-onset atrioventricular (AV) nodal reentry tachycardia, possibly precipitated by overdrive of his autonomic nervous system due to pain and infection. As the percentage of the elderly in our population is growing rapidly and the incidence of AV nodal reentry tachycardia increases with age, emergency physicians should be familiar with this dysrhythmia-its etiology, precipitating factors, presentations, and treatment. It will present more frequently in the future. Published by Elsevier Inc.

A dengue outbreak started in March, 1986 in Rio de Janeiro and spread very rapidly to other parts of the country. The great majority of cases presented classical dengue fever but there was one fatal case, confirmed by virus isolation. Dengue type 1 strains were isolated from patients and vectors (Aedes aegypti) in the area by cultivation in A. albopictus C6/36 cell line. The cytopathic effect (CPE) was studied by electron microscopy. An IgM capture test (MAC-ELISA) was applied with clear and reproducible results for diagnosis and evaluation of virus circulation; IgM antibodies appeared soon after start of clinical disease, and persisted for about 90 days in most patients. The test was type-specific in about 50% of the patients but high levels of heterologous response for type 3 were observed. An overall isolation rate of 46.8% (813 virus strains out of 1734 specimens) was recorded. The IgM test increased the number of confirmed cases to 58.2% (1479 out of 2451 suspected cases). The importance of laboratory diagnosis in all regions where the vectors are present is emphasized.

We present the case of a professional jazz guitarist with temporal lobe epilepsy secondary to an arteriovenous cerebral malformation. The patient underwent a left temporal lobectomy in 1980. After surgery, he presented with severe retrograde amnesia and complete loss of musical interest and capabilities. The patient's musical abilities recovered over time, and he regained his previous virtuoso status. In 2007, his medical history, neuropsychologic functions, and structural magnetic resonance imaging study were examined and revealed a remarkable degree of recovery of memory and musical abilities in the context of extensive temporal lobe resection. The neuropsychologic findings and neuroanatomic features of the magnetic resonance imaging study were analyzed to try to understand the high degree of recovery of both long-term memory and musical processing abilities in this musician. This case reveals the possibility of an unusual degree of cerebral plasticity and reorganization. Additionally, it emphasizes the question of musical virtuosity. This report shows that the musical capabilities of professional musicians, in specific cases, can completely recover even when much of the left temporal lobe has been removed.

Heterozygous p.Asp50Asn mutation in the GJB2 gene in two Cameroonian patients with keratitis-ichthyosis-deafness (KID) syndrome

PubMed Central

2013-01-01

Background Keratitis-Ichthyosis-Deafness (KID) syndrome (OMIM 148210) is a congenital ectodermal defect that consists of an atypical ichthyosiform erythroderma associated with congenital sensorineural deafness. KID appears to be genetically heterogeneous and most cases are caused by GJB2 mutations. Mutations in African patients have been rarely described. Case presentation We report on two unrelated Cameroonian individuals affected with sporadic KID, presenting with the classic phenotypic triad. The two patients were heterozygous for the most frequent p.Asp50Asn mutation. This first report in patients from sub-Saharan African origin supports the hypothesis that the occurrence of KID due to p.Asp50Asn mutation in GJB2 seems not to be population specific. Conclusions Our finding has implication in medical genetic practice, specifically in the molecular diagnosis of KID in Africans. These cases also reveal and emphasize the urgent need to develop appropriate policies to care for patients with rare/orphan diseases in Sub-Saharan Africa, as many of these cases become more and more recognizable.

2016-03-01

Suicide is an intentional self-destructive act. As conceptualization of death as an irreversible end occurs at approximately 8-10 years, attempted and completed suicides are rare before 7 years of age. Studies have suggested that media may contribute to increased suicides in adolescents through social learning. Effects of media on suicides were thoroughly evaluated in children and adolescents who committed suicide after identifying with the subject of a TV program, movie, or book. We present 2 cases at 5 years of age who committed suicide by hanging themselves after watching a TV program. These cases differed from copycat suicides reported in the literature that are performed mostly by adolescents because victims are very young children and because they died without an actual intent to die while they were imitating suicides. By presenting these cases, we want to emphasize that destructive effects of media may involve not only adults and adolescents but also very young children who do not have a completely developed concept of death.

The role of tectonic damage and brittle rock fracture in the development of large rock slope failures

NASA Astrophysics Data System (ADS)

Brideau, Marc-André; Yan, Ming; Stead, Doug

2009-01-01

Rock slope failures are frequently controlled by a complex combination of discontinuities that facilitate kinematic release. These discontinuities are often associated with discrete folds, faults, and shear zones, and/or related tectonic damage. The authors, through detailed case studies, illustrate the importance of considering the influence of tectonic structures not only on three-dimensional kinematic release but also in the reduction of rock mass properties due to induced damage. The case studies selected reflect a wide range of rock mass conditions. In addition to active rock slope failures they include two major historic failures, the Hope Slide, which occurred in British Columbia in 1965 and the Randa rockslides which occurred in Switzerland in 1991. Detailed engineering geological mapping combined with rock testing, GIS data analysis and for selected case numerical modelling, have shown that specific rock slope failure mechanisms may be conveniently related to rock mass classifications such as the Geological Strength Index (GSI). The importance of brittle intact rock fracture in association with pre-existing rock mass damage is emphasized though a consideration of the processes involved in the progressive-time dependent development not only of though-going failure surfaces but also lateral and rear-release mechanisms. Preliminary modelling data are presented to illustrate the importance of intact rock fracture and step-path failure mechanisms; and the results are discussed with reference to selected field observations. The authors emphasize the importance of considering all forms of pre-existing rock mass damage when assessing potential or operative failure mechanisms. It is suggested that a rock slope rock mass damage assessment can provide an improved understanding of the potential failure mode, the likely hazard presented, and appropriate methods of both analysis and remedial treatment.

Hyperammonemic coma after craniotomy: Hepatic encephalopathy from upper gastrointestinal hemorrhage or valproate side effect?: Case report and literature review.

PubMed

Guo, Xiaopeng; Wei, Junji; Gao, Lu; Xing, Bing; Xu, Zhiqin

2017-04-01

Postoperative coma is not uncommon in patients after craniotomy. It generally presents as mental state changes and is usually caused by intracranial hematoma, brain edema, or swelling. Hyperammonemia can also result in postoperative coma; however, it is rarely recognized as a potential cause in coma patients. Hyperammonemic coma is determined through a complicated differential diagnosis, and although it can also be induced as a side effect of valproate (VPA), this cause is frequently unrecognized or confused with upper gastrointestinal hemorrhage (UGH)-induced hepatic encephalopathy. We herein present a case of valproate-induced hyperammonemic encephalopathy (VHE) to illustrate the rarity of such cases and emphasize the importance of correct diagnosis and proper treatment. A 61-year-old woman with meningioma was admitted into our hospital. Radical resection of the tumor was performed, and the patient recovered well as expected. After administration of valproate for 7 days, the patient was suddenly found in a deep coma, and her mental state deteriorated rapidly. The diagnoses of hepatic encephalopathy was confirmed. However, whether it origins from upper gastrointestinal hemorrhage or valproate side effect is uncertain. The patient's condition fluctuated without improvement during the subsequent 3 days under the treatment of reducing ammonia. With the discontinuation of valproate treatment, the patient regained complete consciousness within 48 hours, and her blood ammonia decreased to the normal range within 4 days. VHE is a rare but serious complication in patients after craniotomy and is diagnosed by mental state changes and elevated blood ammonia. Thus, the regular perioperative administration of VPA, which is frequently neglected as a cause of VHE, should be emphasized. In addition, excluding UGH prior to providing a diagnosis and immediately discontinuing VPA administration are recommended.

Two cases of occupational allergic contact dermatitis from a cycloaliphatic epoxy resin in a neat oil: Case Report

Jensen, Charlotte D; Andersen, Klaus E

2003-01-01

Background Metal-working fluids contain complex mixtures of chemicals and metal workers constitute a potential risk group for the development of allergic contact dermatitis. Case presentation Two metal workers developed allergic contact dermatitis on the hands and lower arms from exposure to a neat oil used in metal processing. Patch testing revealed that the relevant contact allergen was a cycloaliphatic epoxy resin, 1,2-cyclohexanedicarboxylic acid, bis(oxiranylmethyl) ester, added to the oil as a stabilizer. None of the patients had positive reactions to the bisphenol A-based epoxy resin in the standard series. Conclusions These cases emphasize that well-known contact allergens may show up from unexpected sources of exposure. Further, it can be a long-lasting, laborious process to detect an occupational contact allergen and cooperation from the patient and the manufacturer of the sensitizing product is essential.

Plasma Cell Gingivitis: An Occasional Case Report.

PubMed

Mishra, M B; Sharma, Swati; Sharma, Alok

2015-01-01

Plasma cell gingivitis, an infrequently observed oral condition, has been clinically characterized by diffuse gingival enlargement, erythema and sometimes desquamation. These lesions are usually asymptomatic, but invariably the patient will complain of a burning sensation in the gingiva and bleeding from the mouth. The diagnosis requires hematological screening in addition to clinical and histopathological examinations. This case report outlines one such case of plasma cell gingivitis in a 15-year-old female caused by use of an herbal, homemade toothpowder. The case presented here highlights the adverse effects and irrational use of herbal agents in dentifrices. At the same time, it emphasizes the need for comprehensive history taking, careful clinical examination and appropriate diagnostic tests in order to arrive at a definitive diagnosis and treatment plan for gingival conditions that are refractory to conventional therapy and to exclude certain malignancies and oral manifestations of systemic diseases.

190 patients presenting intraocular foreign bodies, hospitalized between 1981-1991, are examined. The study of accidents: cases showed a clear prevalence of work accidents--127 cases (66.84%); 86 of these cases occurred in industry (45.26%), the rest of 41 occurred in agriculture (21.58%). The professions most exposed to such accidents are those of locksmith, mechanic in agriculture or automobile industry. The postsurgical evolution and the incidence of complications show that intraocular foreign bodies are wosse-making factors of ocular plagues, because of anatomical structures disorganization, transparency modifications and infectious complications implied, which determined the diminishing of visual acuity in 88.08% of cases. The big percentage of work accidents in the etiology of intraocular foreign bodies emphasize the great importance of foreign the work-protection rules (regarding a especially the wearing of protection glasses) and of introducing of automation in technological processes involving great risks.

Application of the multi-disciplinary thematic seminar method in two homecare cases - a comparative study.

PubMed

Scandurra, Isabella; Hägglund, Maria; Koch, Sabine

2008-01-01

A significant problem with current health information technologies is that they poorly support collaborative work of healthcare professionals, sometimes leading to a fragmentation of workflow and disruption of healthcare processes. This paper presents two homecare cases, both applying multi-disciplinary thematic seminars (MdTS) as a collaborative method for user needs elicitation and requirements specification. This study describes the MdTS application to elicit user needs from different perspectives to coincide with collaborative professions' work practices in two cases. Despite different objectives, the two cases validated that MdTS emphasized the "points of intersection" in cooperative work. Different user groups with similar, yet distinct needs reached a common understanding of the entire work process, agreed upon requirements and participated in the design of prototypes supporting cooperative work. MdTS was applicable in both exploratory and normative studies aiming to elicit the specific requirements in a cooperative environment.

Lymphogranuloma venereum (LGV) is a sexually transmitted infectious disease caused by serovars L1, L2 and L3 of Chlamydia trachomatis. The initial presentation is usually a painless ulcerated papule on the genitalia or distal proctitis. The progression of the infection can lead to major complications: rectal strictures, intestinal obstruction or perforation. We present five cases of LGV proctitis as the initial presentation of the disease. All patients were male, mean age 44.6 years, with positive serology to human immunodeficiency virus (HIV) and promiscuous men who have sex with men (MSM).The initial diagnosis was made by rectosigmoidoscopy indicated for pain and anal discharge. All cases were confirmed by polymerase chain reaction technique in rectal tissue. Endoscopic images obtained showed a great variety of rectal lesions, from mild erythema of the mucosa and ulcers to deep ulcers with elevated borders and purulent exudate. All cases were resolved after treatment with doxycycline for 3 weeks. It emphasizes the importance of suspecting this re-emerging disease in patients with risk factors (HIV and MSM), with the aim of early treatment and to avoid major complications.

Atypical lymphoplasmacytic immunoblastic proliferation (ALPIB) is a rare lymphoproliferative disorder (LPD) associated with autoimmune disease (AID). To further clarify the clinicopathologic, immunohistological, and genotypic findings of ALPIB in lymph nodes associated with well-documented AIDs, 9 cases are presented. These 9 patients consisted of 4 patients with systemic lupus erythematosus, 3 patients with rheumatoid arthritis, and one case each with Sjögren's syndrome and dermatomyositis. All 9 patients were females aged from 25 to 71 years with a median age of 49 years. Four cases presented with lymphadenopathy as the initial manifestation. In 4 patients, immunosuppressive drugs were administered before the onset of lymph node lesion. However, none of the 9 patients received methotrexate therapy. The present 9 cases were characterized by : (i) prominent lymphoplasmacytic and B-immunoblastic infiltration ; (ii) absence of pronounced arborizing vascular proliferation ; (iii) absence of CD10(+) "clear cells" ; (iv) presence of hyperplastic germinal center in 7 cases ; (v) immunohistochemistry, flow cytometry, and polymerase chain reaction demonstrated a reactive nature of the T- and B-lymphocytes ; and (vi) on in situ hybridization, there were no Epstein-Barr virus -infected lymphoid cells in any of the 9 cases. Overall 5-year survival of our patients was 83%. The combination of clinical, immunophenotypic, and genotypic findings indicated that the present 9 cases can be regarded as having an essentially benign reactive process. Finally, we emphasized that ALPIB should be added to the differential diagnostic problems of atypical LPDs, particularly lymph node lesions of IgG4-related diseases.

Radiculopathy in the setting of lumbar nerve root compression due to an extradural intraforaminal lipoma: a report of 3 cases.

PubMed

Loriaux, Daniel B; Adogwa, Owoicho; Gottfried, Oren N

2015-07-01

A true adult spinal lipoma is an exceedingly rare cause of lumbar compression neuropathy. Only 5 cases of true extradural intraforaminal lipomas have been documented in the medical literature. The diagnostic criteria and treatment guidelines for this specific lipoma have yet to be established. This report features 3 histologically confirmed cases of extradural intraforaminal spinal lipomas that recently presented to the authors' practice. In addition, the literature was surveyed to include the 5 previously reported cases of true adult extradural intraforaminal spinal lipomas. The consistency in presentation, response to surgical intervention, and postoperative recovery in these 8 cases supports surgical intervention at the time of diagnosis. The authors' findings support elevated clinical suspicion, efficient diagnosis based on MRI, and early surgical intervention for this rare pathological entity. All cases presented in this report were symptomatic and occurred in the absence of other significant pathologies such as general spinal epidural lipomatosis, intradural lesions, tethering, or severe degenerative stenosis or herniated discs. The clinical, neuroradiological, and histological findings characteristic of a true adult extradural intraforaminal lipoma are emphasized to differentiate this lesion from the more common etiologies for lumbar compression neuropathy. Heightened awareness and clinical suspicion for the focal, foraminal spinal lipoma as a cause of radiculopathy symptoms will enable more efficient diagnosis and treatment.

Abstract Rationale: We present a rare case of malignant pheochromocytoma with thoracic metastases during pregnancy that presented with symptoms of myelopathy and was treated with circumferential decompression, stabilization, and radiation. The management of this unique case is not well documented. The clinical manifestations, imaging results, pathological characteristics, treatment and prognosis of the case were analyzed. Patient concerns: A 26-year-old pregnant woman with a history of paroxysmal hypertension during the second trimester presented with lower extremity weakness, numbness, urinary incontinence, and back pain. Imaging studies revealed a right adrenal pheochromocytoma, multiple metastases at T8, T11, T12, and the pelvis girdle causing significant multilevel cord compression and significant osteolytic lesions at T11 and T12. Diagnoses: We believe this is the first reported case of metastatic pheochromocytoma of the thoracic spine presenting with symptoms of myelopathy during pregnancy. Interventions: A healthy neonate was delivered by emergency caesarean section at 34 weeks. Subsequently, the patient underwent a circumferential spinal cord decompression and a stabilization procedure. Outcomes: The patient's neurological deficits improved significantly after the surgery, and the postoperative period was uneventful at the 6-month follow-up visit. Lessons: This article emphasizes that metastatic pheochromocytoma of the spine, although rare, should be part of the differential when a patient presents with elevated blood pressure, weakness, and urinary incontinence.

The purpose of the present study was to emphasize the technique of micro-marsupialization as an alternative for the treatment of mucus retention phenomena. Out of 41 patients, 14 were selected for treatment by the micro-marsupialization technique on the basis of clinical criteria. Patient age ranged from 5-9 years. The technique was performed as follows: the area was disinfected with 0.1% iodine; a topical anesthetic was applied to cover the entire lesion for approximately 3 min; a 4.0 silk suture was passed through the internal part of the lesion along its widest diameter; and a surgical knot was made. Of the original 14 patients treated by the micro-marsupialization technique, 12 presented full regression one week after treatment. Recurrence occurred in two cases. It was possible to conclude that the micro-marsupialization technique is an alternative to be considered, especially in pediatric dentistry.

Tongue-tie or ankyloglossia is the congenital short thick lingual frenulum resulting in reduced mobility of the tongue. It limits the possibilities of the extension such as the protrusion and elevation of the tip of the tongue due to either the short of frenulum or genioglossus muscle or both. It can be observed at different ages with specific indications for treatment for each group and cause problems in the feeding, dental hygiene, speech, appearance, and self-esteem of affected patients. Although various degrees of the tongue-tie are mostly observed from the tip of tongue to the base of tongue, sometimes it may present unusually. The present article reports an unusual unique pattern of ankyloglossia where lingual frenum was exceptionally extended and merged with mandibular labium frenum. Reported case is one of the rarest types of ankyloglossia and emphasizes on its clinical implications, need for modifying diagnostic criteria, surgical management, and postoperative exercises.

Fluorescein is a chemical dye frequently used in eye diseases to assess blood flow in the retina, choroid tissue, and iris. Although it has many known adverse effects, it has not previously been reported to lead to jaundice. The purpose of this case report was to emphasize that for patients presenting at the emergency department with jaundice symptoms, it should not be forgotten by emergency physicians that jaundice can develop after fluorescein angiography. Case: A 65-year-old woman presented at the emergency department with extensive jaundice that had developed on her entire body a few hours after fluorescein angiography applied because of vision impairment. The test results for all the diseases considered to cause jaundice were normal,and fluorescein-related jaundice was diagnosed. Conclusion: A detailed anamnesis should be taken when jaundice is seen in patients who have undergone fluorescein angiography, and it should not be forgotten that fluorescein dye is a rare cause of jaundice.

Systemic rhabdomyosarcoma presenting as leukemia: case report with ultrastructural study and reviews.

PubMed

1987-08-01

A 20-year-old white male was initially suspected clinically and pathologically of having an acute lymphoblastic leukemic process because of fatigue, severe anemia, thrombocytopenia, a leuko-erythroblastic peripheral blood picture, and a diffusely infiltrated bone marrow. Subsequent review of the bone marrow material indicated cytologic features consistent with either an embryonal, undifferentiated small cell mesenchymal malignancy or reticulo-endothelial malignancy. Ultimately, the electron microscopic (EM) study of the tumor proved to be diagnostic of rhabdomyosarcoma. An extensive search for a primary site of rhabdomyosarcoma did not show any lesion, although the genitourinary region was clinically suspected. The clinical course was a rapidly downhill one with extensive bone and CNS involvement. The patient died 5 months later. An autopsy permit was not obtained. This case emphasizes the occasional tendency of rhabdomyosarcoma to masquerade as a hematopoietic malignancy at the time of presentation and the usefulness of EM study in confirming a diagnosis.

Takotsubo cardiomyopathy also known as transient balooning syndrome is an increasingly reported phenomenon characterized by acute reversible apical or midventricular dysfunction. This stress- induced cardiomyopathy mimics myocardial infarction, but without significant coronary artery disease, and rarely presents in perioperative period. We report a case of postmenopausal woman scheduled to undergo elective cholecystectomy, with no history of coronary artery disease. She presented perioperatively with Takotsubo cardiomyopathy by unique manifestation-asystoly. This uncommon cause of cardiac arrest during anaesthesia was possibly induced by preoperative emotional stress. There was full recovery thanks to intensive management. In Takotsubo cardiomyopathy related cardiogenic shock we used the calcium sensitiser levosimendan successfully. Takotsubo cardiomyopathy has an excellent long-term prognosis and nearly all patients have full recovery of left ventricular function. We emphasize the importance of heavy premedication by stress compromised patients and the need of sufficiently deep anaesthesia and analgesia during surgeries.

The persistence of the omphalo-enteric conduct is a rare, but possible, cause of pathology in children. Haemorrhage and intestinal occlusion are the most frequent clinical presentations, usually in infants. We describe the case of a 10 year old boy, who was admitted in our department for what seemed first to be an acute appendicitis. During hospitalization, the clinical picture turned on to an intestinal occlusion, and the patient finally required surgery. We performed exploratory laparotomy and we discovered a mechanical occlusion by persistence of the omphalo-enteric conduct, which was treated according to standard protocols. The post-operative course was good, and the child was discharged 8 days after surgery. This case emphasizes that the persistence of the omphalo-enteric conduct should be sought as the source of symptoms in any child presenting with intestinal occlusion.

Metastases to the pituitary gland are rare events, and usually indicate widespread malignant disease. The lung and the breast are the most common sites of primary tumors that metastasize to the pituitary gland.Metastases are more frequent in older patients and the most common symptoms at presentation are diabetes insipidus and visual alterations. 72-year-old white woman was treated for a breast carcinoma with right superoexternal quadrantectomy, radiotherapy, and hormone therapy. Twelve years later, the patient presented with bone pain, bilateral progressive visual decline, and onset of hypopituitarism. A diagnosis of secondary bone involvement and pituitary metastasis was made. This was an unusual disease course, and stresses the importance of intensive follow-up in patients with breast cancer even many years after the initial diagnosis This case emphasizes that diagnosis can be difficult and controversial when relapse occurs at uncommon sites.

2016-01-01

A 23-year-old man with a history of alcoholism presented with vomiting, fever, and sharp epigastric pain radiating to the back and flanks. He was diagnosed as a case of acute alcoholic pancreatitis on the basis of clinical findings and investigations. On the next day of presentation, he developed sudden bilateral visual loss. His best-corrected visual acuity was finger counting at one-foot distance in both eyes. He had diffuse whitening in the circumpapillary area, haloes around the retinal vessels (Purtscher flecken) and intra-retinal hemorrhages on ophthalmoscopic examination. Optical coherence tomography revealed bilateral macular edema. These findings were characteristic of Purtscher-like retinopathy. The patient showed systemic and visual improvement at 8 weeks follow-up after receiving the conventional treatment for acute alcoholic pancreatitis. This case emphasizes the importance of fundus examination by an ophthalmologist in the diagnosis of this rare under-diagnosed entity. PMID:27433040

Pott's disease is a health problem in developing countries and its diagnosis in children is a challenge. Here we present the case of a two-year-old boy with Pott's disease involving T1 to T3 thoracic vertebrae. The clinical presentation was characterized by difficulty walking, fever, cough, and dyspnea. At physical examination, kyphosis and bony prominence were observed in the cervicodorsal area. A positive tuberculin test was obtained, and Mycobacterium tuberculosis was isolated via culture of the gastric aspiration sample. The spine MRI showed a chronic abscess, destruction of two vertebrae, and bone marrow compression. The patient experienced some improvement with anti-TB therapy. Here, we emphasize the importance of giving consideration to the clinical suspicion for the early detection of this condition, as well as a quick TB-treatment start so as to avoid the disability and mortality associated to this disease.

Corticobasal degeneration (CBD) is a neurodegenerative disease characterized pathologically by neuronal loss, gliosis and tau deposition in neocortex, basal ganglia and brainstem. Typical clinical presentation is known as corticobasal syndrome (CBS) and involves the core features of progressive asymmetric rigidity and apraxia, accompanied by other signs of cortical and extrapyramidal dysfunction. Asymmetry is also emphasized on neuroimaging. To describe a series of cases of CBD with symmetric clinical features and to compare clinical and imaging features of these symmetric CBD cases (S-CBD) to typical cases of CBS with CBD pathology. All cases of pathologically confirmed CBD from the Mayo Clinic Rochester database were identified. Clinical records were reviewed and quantitative volumetric analysis of symmetric atrophy on head MRI using atlas based parcellation was performed. Subjects were classified as S-CBD if no differences had been observed between right- and left-sided cortical or extrapyramidal signs or symptoms. S-CBD cases were compared to 10 randomly selected typical CBS cases. Five cases (2 female) met criteria for S-CBD. None had limb dystonia, myoclonus, apraxia or alien limb phenomena. S-CBD cases had significantly less asymmetric atrophy when compared with CBS cases (p=0.009); they were also younger at onset (median 61 versus 66 years, p<0.05) and death (67 versus 73 years, p<0.05). Family history was present in 40% of S-CBD cases. CBD can have a symmetric presentation, clinically and radiologically, in which typical features of CBS, such as limb apraxia, myoclonus, dystonia and alien limb phenomenon, may be absent.

2018-05-23

The ventriculus terminalis (VT) is a very small ependymal-lined residual lumen in the conus medullaris. It is normally present in all subjects during fetal development. VT in adults appears as an unusual pathology with an uncertain pathogenesis. In this paper, we described three case reports of symptomatic fifth ventricle cystic dilations. All of them were female and their mean age was 59 years. We treated them surgically and all three patients were improved based on clinical and imaging assessments. Our cases suggested that surgical decompression was a safe and effective treatment in symptomatic patients and the neurosurgeons should be aware of such rare situations. A complete list of differential diagnosis about other cystic dilations of the conus medullaris should be emphasized to select the correct clinical approach.

Hemolytic disease of the fetus and newborn occurs when maternal IgG antibodies cross the placenta and cause hemolysis of fetal red blood cells. Kp(a) is a low frequency red blood cell antigen that has rarely been implicated in hemolytic disease of the fetus and newborn. The few reported cases attributed to anti-Kp(a) have typically had minimal clinical consequences. We report a critically ill neonate who presented with purpura, respiratory failure, severe liver dysfunction, hyperbilirubinemia, hypoglycemia and anemia. This case report broadens the spectrum of neonatal disease associated with anti-Kp(a), addresses the evaluation of hemolysis with liver failure in a neonate, and emphasizes the importance of screening for antibodies to low frequency red blood cell antigens in suspected hemolytic disease of the fetus and newborn.

We hereby present a case of planned complex suicide. In this case study, we report a teen-aged girl who committed suicide by strangulating herself, and subsequently fell from the 13th floor of a housing apartment. The planned complex suicide was substantiated by the presence of a suicide note and a photograph captured in a mobile handset. To the best of our knowledge, it is the first case involving self-strangulation and fall from height, in which the photograph was stored in the handset. This is to further emphasize that objects like mobile handsets can be important in determining the cause and manner of death. The available evidence at the site of incident should be explored meticulously in order to arrive at a proper conclusion. Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.

Case report: delayed presentation of postural headache in an adolescent girl after microscopic lumbar discectomy.

2008-10-01

To discuss the diagnostic and therapeutic challenges presented by an adolescent girl with delayed postural headaches and photophobia that occurred three months after an apparently uncomplicated microscopic lumbar discectomy. A previously healthy girl was admitted to our hospital with a one-week history of an unremitting, frontal-retroorbital postural headache and photophobia. Three months before admission, the patient had undergone a L5-S1 left hemilaminotomy and foraminotomy with microdiscectomy for excision of a herniated intervertebral disc. Conservative treatment failed to provide symptomatic relief. Cranial magnetic resonance imaging showed enhancement of the pachymeninges, consistent with intracranial hypotension. A chronic cerebrospinal leak was identified by high-resolution computed tomography (CT) myelography. Epidural blood patches were performed, with and without CT guidance, that provided temporary relief of the patient's symptoms; however, direct suture plication of the dural tear was eventually required for definitive treatment. This case emphasizes that delayed presentation of dural injury may occur after lumbar surgery and describes the potential therapeutic implications for this unusual complication.

Linear morphea en coup de sabre (ECDS) is a form of localized scleroderma that predominantly affects the pediatric population, with a median age of 10 years at presentation. The existence of neurologic findings in association with ECDS has been well described in the literature. Here we describe 4 patients with ECDS who presented with headaches, which were typical migraines in 3 of the patients. The headaches preceded the onset of cutaneous findings by at least 6 months. Our patients' cases emphasize both the importance of recognizing headaches as a harbinger of ECDS and the necessity of performing thorough cutaneous examination in patients with unexplained headaches or other neurologic disease.

2010-01-01

Introduction We describe a case of rare complication of typhoid fever in a seven-year-old child and review the literature with regard to other rare causes of bleeding per rectum. Dieulafoy's lesion is an uncommon but important cause of recurrent gastrointestinal bleeding. Dieulafoy's lesion located extragastrically is rare. We report a case of typhoid ulcer with Dieulafoy's lesion of the ileum causing severe life-threatening bleeding and discuss the management of this extremely uncommon entity. Case presentation As a complication of typhoid fever, a seven-year-old Kurdish girl from Northern Iraq developed massive fresh bleeding per rectum. During colonoscopy and laparotomy, she was discovered to have multiple bleeding ulcers within the Dieulafoy's lesion in the terminal ileum and ileocecal region. Conclusion Although there is no practical way of predicting the occurrence of such rare complications, we emphasize in this case report the wide array of pathologies that can result from typhoid fever.

The identification of hazards to the life and health of industrial workers will be presented in the context of statutory accident insurance in Germany at the turn of the century. From the interplay of industrial and socio-political developments the question arose of how long term risks and illnesses, in particular poisoning, were to be defined. The inclusion of occupational diseases in accident insurance certainly emphasized the biographical dimension of illness, but complicated the preventative function of the 1925 Occupational Disease Ordinance.

Methods to identify structural similarities between proteins in cases of significant, moderate to low, or virtually absent sequence similarity are discussed. The detection and evaluation of structural relationships is emphasized as a central aspect of protein modeling, distinct from the more technical aspects of model building. Computational techniques to generate and complement comparative protein models are also reviewed. Two examples, P-selectin and gp39, are presented to illustrate the derivation of protein model structures and their use in experimental studies. PMID:7505680

Land-use planning has triggered debates on social and environmental values, in which two key questions will be faced: one is how to see different planning simulation results instantaneously and apply the results back to interactively assist planning work; the other is how to ensure that the planning simulation result is scientific and accurate. To answer these questions, the objective of this paper is to analyze whether and how a bridge can be built between qualitative and quantitative approaches for land-use planning work and to find out a way to overcome the gap that exists between the ability to construct computer simulation models to aid integrated land-use plan making and the demand for them by planning professionals. The study presented a theoretical framework of land-use planning based on scenario analysis (SA) method and multiagent system (MAS) simulation integration and selected freshwater wetlands in the Sanjiang Plain of China as a case study area. Study results showed that MAS simulation technique emphasizing quantitative process effectively compensated for the SA method emphasizing qualitative process, which realized the organic combination of qualitative and quantitative land-use planning work, and then provided a new idea and method for the land-use planning and sustainable managements of land resources.

Study results showed that MAS simulation technique emphasizing quantitative process effectively compensated for the SA method emphasizing qualitative process, which realized the organic combination of qualitative and quantitative land-use planning work, and then provided a new idea and method for the land-use planning and sustainable managements of land resources.

Umbilical metastasis or Sister Mary Joseph's nodule as a very early sign of an occult cecal adenocarcinoma.

PubMed

Salemis, Nikolaos S

2007-01-01

Umbilical metastasis (Sister Mary Joseph's nodule) is a rare occurrence and indicates, in most of the patients, an advanced intraabdominal malignancy. It may be the first sign of an underlying adenocarcinoma, originating mainly from the gastrointestinal or genitourinary tract. An extremely rare case of a Sister Mary Joseph's nodule is described herein, where the metastatic umbilical nodule was the first sign of a cecal adenocarcinoma and became evident 8 months before the onset of the disease. Diagnostic evaluation and surgical management are discussed along with a review of the literature. This case is presented in order to emphasize the need for thorough investigation of any umbilical lesion especially in elderly patients.

A 24-year-old Japanese woman developed anterocollis, weakness of the proximal arms, and subsequent cognitive impairment. A neurological examination revealed amyotrophic lateral sclerosis (ALS) without a family history. Systemic muscle atrophy progressed rapidly. Cerebral MRI clearly exhibited high signal intensities along the bilateral pyramidal tracts. An analysis of the FUS gene revealed a heterozygous two-base pair deletion, c.1507-1508delAG (p.G504WfsX515). A subset of juvenile-onset familial/sporadic ALS cases with FUS gene mutations reportedly demonstrates mental retardation or learning difficulty. Our study emphasizes the importance of conducting a FUS gene analysis in juvenile-onset ALS cases, even when no family occurrence is confirmed.

A 10-year-old girl with anorexia nervosa developed the refeeding syndrome following cautious reintroduction of nutrition, emphasizing that even with cautious refeeding a shift in fluid, glucose, and electrolytes can still occur, increasing the risk of morbidity and mortality in this ever growing vulnerable group. Biochemical, nutritional, and anthropometrical monitoring in the patient, who followed a conservative refeeding program after a prolonged period of nutritional inadequacy. The refeeding syndrome presented itself with hypophosphatemia, hypotension, and cardiac abnormalities whilst refeeding at 25 kcal/kg (600 kcal/day). Comprises of a literature review, highlighting this case as the youngest reported case of refeeding syndrome in anorexia nervosa. Discussion focuses on the possible deleterious affects that carbohydrates may have in exacerbating the refeeding syndrome. Copyright © 2009 Wiley Periodicals, Inc.

Aggregatibacter actinomycetemcomitans most commonly causes periodontitis but has been reported to infect heart valves, soft tissue, brain and lungs, and distal bones. Osteomyelitis distal to the jaw is rarely described. We report an unusual and rare case of chronic osteomyelitis caused by A. actinomycetemcomitans in the toe of a paediatric patient, and review the available literature. The infection was managed with intravenous antibiotics followed by oral antibiotics. This is an unusual presentation of A. actinomycetemcomitans causing chronic osteomyelitis presumed due to nidation in a minimally damaged bone, associated with bacteraemia of an oral commensal. It occurred in the toe, without obvious dental predisposition; associated with minimal clinical disturbance and with muted immune response.

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor in gastrointestinal tracts; however, the synchronous or metachronous coexistence of GIST with additional primary malignancy is not common.Here, we present an unusual case of gastric GIST with metachronous primary lung adenocarcinoma diagnosed during his adjuvant treatment with oral receptor tyrosine kinase inhibitor imatinib mesylate (400 mg daily). After 6-month use of imatinib, the patient suffered from dry cough and dyspnea. Subsequent lung biopsy demonstrated adenocarcinoma with diffuse interstitial changes.Our research emphasizes the possibility of an additional primary tumor with GIST, and reminds the clinicians to strengthen the surveillance of the additional cancer during the follow-up of GIST patients.

Schultz, Megan L; Kostic, Mark; Kharasch, Sigmund

2017-01-06

Opiates are frequently prescribed postpartum for pain relief after cesarean delivery, episiotomies, and headaches. It is estimated that greater than 30% of breast-feeding mothers in the United States are prescribed opiates for pain relief associated with childbirth. Many opiates are readily transferred to human milk, although life-threatening events are rare. We report a 6-day-old breast-feeding infant whose mother was taking hydromorphone for pain relief from a cesarean delivery and whose clinical course was suggestive of opiate toxicity. This case emphasizes the importance of thorough medication history taking in postpartum breast-feeding mothers whose infants may present with symptoms of opiate toxicity. Semisynthetic opiates are frequently not detected on emergency department urine toxicology screens. The pertinent literature is reviewed.

Dirofilaria immitis and D. repens are mosquito-borne nematodes that primarily infect canids, and can also cause mild to serious superficial or visceral infection in humans. In the present survey, peripheral blood from 150 asymptomatic dogs from Serbia were examined using the modified Knott's technique. Dirofilaria immitis, identified based on morphological and morphometric characteristics, was prevalent in dogs not receiving preventative treatment (in 44% and 60% of pound and pet dogs, respectively). These results, together with findings of autochthonous cases of subcutaneous D. repens infection in human patients from Southeastern Serbia emphasize the need for further investigations of this veterinary and public health problem.

2016-06-01

Lymphogranuloma venereum (LGV) is sexually transmitted infection caused by serovars of Chlamydia trachomatis, mostly seen among HIV-positive men who have sex with men. The first three reports of possible LGV in Slovenia were from April to June 2015, followed by a confirmed case of LGV in August 2015. We present the case of an HIV-positive MSM that presented with an anorectal abscess, discharge, lymphadenopathy, and unusual perianal plaque. Gonococcal proctitis was assumed and he received empirical antibiotic treatment, after which only intermittent improvement occurred. After a positive test result for chlamydial infection, but without a response to azithromycin treatment, LGV was suspected. Treatment according to the guidelines was introduced. When doxycycline therapy started, rapid improvement was observed, and it was therefore assumed that the LGV infection had been successfully treated. Two similar cases with an unusual anorectal presentation and an excellent response to antibiotic therapy for LGV were observed at the same center shortly thereafter. While pointing out possible delays and limitations in diagnostic procedures at self-pay facilities, the need for better access to high quality STI management in public and in private services is emphasized. Enhanced surveillance and testing guidelines could reveal a hidden LGV epidemic among MSM in Slovenia.

Background Oral submucous fibrosis (OSF) is an insidious chronic condition characterized by restricted mouth opening. Prosthetic rehabilitation is challenging for OSF patients as obtaining a good impression requires adequate mouth opening. The aim of the present review is to systematically present the data from case reports published in the English-language literature. Method A comprehensive search of the literature databases (PubMed, Medline, SCOPUS, Web of Science and Google Scholar) along with the references of published articles on prosthetic rehabilitation in OSF patients published to date was conducted. Keywords included a combination of ‘Oral submucous fibrosis’, ‘prosthesis’, ‘dentures’ and/or ‘restricted mouth opening’. Citations from selected references and bibliographic linkages taken from similar cases were included in this review. The inclusion criteria selected for case reports on prosthetic rehabilitation in OSF patients, and cases of restricted mouth opening due to causes other than OSF were excluded from the study. Results A total of 21 cases were identified and analysed from 17 papers published in the English-language literature. Of these, 9 cases employed the sectional denture technique, 4 cases emphasized the need-based treatment approach in which conventional methods were modified, and 4 cases used mouth exercising devices. Finally, 1 case each involved, flexible denture, oral screen prosthesis, oral stents, surgery in conjunction with dentures. Conclusion Prosthetic rehabilitation in OSF patients is a multifaceted approach and should be patient specific, although sectional dentures have achieved the best results. PMID:28877246

AL Amyloidosis is known to be a systemic disease affecting multiple organs and tissue while it's rare that patients present with gastrointestinal symptoms at first and later develop multiple-organ dysfuction. Clinical signs are not specific and the diagnosis is rarely given before performing immunofixation and endoscopy with multiple biopsies. We would like to emphasize the value of precise diagnostic process of AL amyloidosis. In this case report, we describe a 56-year-old man who presented with recurrent periumbilical pain for 4 months and gradually worsened over a month. After a series of tests, he was finally diagnosed with primary systemic AL amyloidosis. He was treated with a chemotherapy regimen (Melphalan, dexamethasone and thalidomide) achieving a good clinical response. On account of the high misdiagnosis rate, establishing the most precise diagnosis in first time with typing amyloidogenic protein becomes increasingly vital. Although the presenting feature is usually nonspecific, AL amyloidosis ought to be considered when multiple organs are involved in a short period.

Cushing disease in children and adolescents, especially with multiple pituitary adenomas (MPAs), is very rare. We report 17-year-old boy with MPAs. He presented with a vertebral compression fracture, weight gain, short stature, headache, and hypertension. On magnetic resonance imaging (MRI), only a left pituitary microadenoma was found. After surgery, transient clinical improvement was observed but headache and hypertension were observed again after 3 months later. Follow-up MRI showed a newly developed right pituitary microadenoma 6 months after the surgery. The need for careful clinical and radiographic follow-up should be emphasized in the search for potential MPAs in patients with persistent Cushing disease.

We report 4 pediatric cases of ureteropelvic junction obstruction involving delayed progression of initially mild postnatal hydronephrosis. All 4 children became symptomatic; however, 3 already had a substantial decrement of ipsilateral kidney function by the time of diagnosis. Two of these 3 patients had previous renal scintigraphy demonstrating normal differential function. We caution that counseling regarding hydronephrosis should emphasize the importance of prompt re-evaluation for any symptoms potentially referable to delayed presentation of ureteropelvic junction obstruction, irrespective of initial hydronephrosis grade. Future studies are needed to determine the optimal follow-up regimen for conservative management of hydronephrosis. Copyright © 2015 Elsevier Inc. All rights reserved.

Cannabis-induced bullous lung disease leading to pneumothorax: Case report and literature review.

2017-05-01

Marijuana use has been increasing in the United States among college students and young adults. Marijuana use has been associated with bullous lung disease which can lead to pneumothorax. There are other recreational drugs like methylphenidate, cocaine and heroin which have been associated with pneumothorax. We present a case of a 30-year-old man with spontaneous pneumothorax associated with marijuana use. The patient had no medical conditions and presented to the emergency room with chest pain. The physical examination revealed decreased breath sound on the right side of the chest. Bed side ultrasound of chest showed stratosphere sign, absent lung sliding; consistent with right-sided pneumothorax. The patient underwent placement of a chest tube. Computed tomography chest scans performed on day two also showed bullous lung disease in the right lung. Serial x-rays of the chest showed re-expansion of the lung. Despite the beneficial effects of Marijuana there are deleterious effects which are emphasized here. This case highlights the need for further studies to establish the relationship between marijuana use and lung diseases in the absence of nicotine use.

Misreporting signs of child abuse: the role of decision-making and outcome information.

PubMed

Lindholm, Torun; Sjöberg, Rickard L; Memon, Amina

2014-02-01

Two studies provided evidence that a decision to report an ambiguous case of child abuse affected subsequent memory of the case information, such that participants falsely recognized details that were not presented in the original information, but that are schematically associated with child abuse. Moreover, post-decision information that the child had later died from abuse influenced the memory reports of participants who had chosen not to report the case, increasing their reports of false schema-consistent details. This suggests that false decision-consistent memories are primarily due to sense-making, schematic processing rather than the motivation to justify the decision. The present findings points to an important mechanism by which decision information can become distorted in retrospect, and emphasize the difficulties of improving future decision-making by contemplating past decisions. The results also indicate that decisions may generate false memories in the apparent absence of external suggestion or misleading information. Implications for decision-making theory, and applied practices are discussed. © 2013 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

Mandibular Actinomyces osteomyelitis complicating florid cemento-osseous dysplasia: case report

PubMed Central

2011-01-01

Background Apart from neoplastic processes, chronic disfiguring and destructive diseases of the mandible are uncommon. Case Presentation We report, perhaps for the first time, the simultaneous occurrence of two such conditions in one patient, in a case that emphasizes the importance of bone biopsy in establishing the correct diagnosis. Florid cemento-osseous dysplasia (FCOD) is a chronic, disfiguring condition of the maxillofacial region. This relatively benign disease is primarily observed in middle-aged women of African ancestry. Cervicofacial actinomycosis is an uncommon and progressive infection caused by bacilli of the Actinomyces genus that typically involves intraoral soft tissues but may also involve bone. The accurate diagnosis of actinomycosis is critical for successful treatment. A diagnosis of osteomyelitis caused by Actinomyces bacteria was diagnosed by bone biopsy in a 53 year-old African-American woman with a longstanding history of FCOD after she presented with a new draining ulcer overlying the mandible. Conclusions Clinicians should be aware of the possibility of actinomycosis arising in the setting of FCOD, and the importance of bone biopsy and cultures in arriving at a definitive and timely diagnosis.

2012-01-01

Enterobius vermicularis also known commonly as pinworm is the most common intestinal parasite. It is a nematode that inhabits the human terminal ileum, colon and appendix. The fertilized female migrates to the perianal area where eggs are deposited but occasionally introduces itself into adjacent orifices, most commonly the female genitourinary tract. Thus the eggs can be seen in the vaginal smear as a result of contamination. We report a case wherein the patient presented with signs and symptoms of vulvovaginitis. In her vaginal smear there were eggs of Enterobius vermicularis which showed a coiled larva within it. In the background there were plenty of acute inflammatory cells. This patient responded favorably to antihelminthics. We report this case to highlight the morphology of the parasite and also to emphasize that such findings should not be neglected. Timely reporting and appropriate treatment of such cases will prevent further complications of this parasite including endometritis, salphingitis and peritonitis. PMID:22438633

Retrospective study made on 140 renal surgical biopsies (RSB) performed throughout the past 4 years in our Unit. The technique's effectiveness and morbidity are emphasized and the surgical technique and type of anaesthesia described. The sample obtained was enough to perform an essay in 100% cases, and a diagnosis was reached in 98.5%. Thirty-nine patients (27.8%) presented complications, 13 (9.2%) of which were directly related to the surgical technique. No case required blood transfusion and no deaths were reported. The type of anaesthesia used was: local plus sedation in 104 (74.2%) cases, rachianaesthesia in 10 (7.1%) and general in 26 (18.5%). The same approach was used in all patients: minimal subcostal lumbotomy, using Wilde's forceps to obtain the samples. It is believed that RSB is a highly effective, low mortality procedure, easy and quick to perform, and suitable for selected patients.

This paper addresses the issue of evaluating the Quality of Experience (QoE) for Internet of Things (IoT) applications, with particular attention to the case where multimedia content is involved. A layered IoT architecture is firstly analyzed to understand which QoE influence factors have to be considered in relevant application scenarios. We then introduce the concept of Multimedia IoT (MIoT) and define a layered QoE model aimed at evaluating and combining the contributions of each influence factor to estimate the overall QoE in MIoT applications. Finally, we present a use case related to the remote monitoring of vehicles during driving practices, which is used to validate the proposed layered model, and we discuss a second use case for smart surveillance, to emphasize the generality of the proposed framework. The effectiveness in evaluating classes of influence factors separately is demonstrated. PMID:27918437

Subarachnoid hemorrhage (SAH) of spinal origin is uncommon in clinical practice, and spinal schwannomas associated with SAH are even more rarely reported. We report an unusual case of spinal SAH mimicking meningitis with normal brain computed tomography (CT)/magnetic resonance imaging (MRI) and negative CT angiography. Cerebrospinal fluid examination results were consistent with the manifestation of SAH. Spinal MRI performed subsequently showed an intradural extramedullary mass. The patient received surgery and was finally diagnosed with spinal cord schwannoma. A retrospective chart review of the patient was performed. We describe a case of SAH due to spinal cord schwannoma. Our case highlights the importance of careful history taking and complete evaluation. We emphasize that spinal causes should always be ruled out in patients with angionegative SAH and that schwannoma should be considered in the differential diagnosis of SAH etiologies even though rare.

Cosmetic laser use has many pros and cons. The worldwide use of laser for body hair removal has led to many medical complications. Unsupervised use of the laser for hair removal in vulva may result in many problems and can merely damage the vulva, although rarely, affecting the body image. This rare and novel case report is a 21 year old virgin who presented with acute urinary retention and cryptomenorrhea due to complete synlabia secondary to unsupervised vulval laser hair removal. The urinary retention was relieved by suprapubic catheterization initially. During examination under anesthesia, the fused labia were separated by a surgical incision with drainage of hematocolpos and then, a Foley's urethral catheter was inserted. She had an uneventful recovery. We report this case to emphasize on the supervised use of laser by trained and qualified personnel for hair removal in vulva to minimize its complications.

Systemic amyloidosis is a rare disease, in which the heart involvement is rather frequent and determines survival remarkably. Regarding the disease and organ involvement, new diagnostic procedures help to establish the diagnosis and to start the adequate treatment as soon as possible. Cardiac involvement is more likely to be characterised by monoclonal immunglobulin free light chain (AL amyloidosis) type and transthyretin type. In case of AL amyloidosis, heart involvement can lead to serious consequences. Biomarker assessments for cardiac function are important to determine disease severity at the beginning and to measure response to the treatment. In case of amyloidosis, the incidence of the heart involvement grows with age. The prevalence is not known exactly, but probably there are more cases than recognised. The authors present the clinical signs and diagnostic methods, emphasizing the importance of the cardiac examination methods. Orv Hetil. 2017; 158(46): 1811-1818.

Herpes simplex infections are potentially a life-threatening situation for immunocompromised as well as critically ill patients. The correct diagnosis is made more difficult in comatose patients by the fact that the characteristic symptom of extreme pain cannot be registered. The clinical dermatological findings (polycyclic configuration, easily bleeding ulcers) are thus especially important in patients under intensive care conditions. As examples, the cases of 3 critically ill patients (subarachnoid bleeding or head injury) developing therapy-resistant, flat sacral or perioral skin ulcers with peripheral blisters are presented. Herpes simplex virus was confirmed immunohistologically and in the smear test. All patients subsequently died. These cases emphasize that patients in the intensive care unit are in danger of developing a chronic persistent Herpes simplex infection due to latent immunosuppression. Chronic persistent Herpes infections may be underrated in intensive therapy, and must always be ruled out in case of therapy-resistant erosions or ulcerations.

In the latter part of the 20th century, healthcare reform sparked a transition in the nursing curriculum from acute care to primary and secondary care. Faculty responded to this challenge by redesigning curricula in creative ways. The transitional curriculum introduced community clinical experiences designed to challenge students to practice in diverse, nontraditional sites and in more independent ways. Such practice requires the nurse to function as designer, coordinator, and manager of patient care in addition to the traditional provider role. Additionally, the transitional curricula emphasized the roles of communicator, educator, facilitator, listener, and advocate to a greater degree. For students to achieve competence in the above roles, the curriculum must include learning activities that allow them to practice as case managers in the community. This paper presents the "Seven A's" as a framework for students to gain an understanding of and engage in the role and process of case management in the community.

Abstract Abdominal hibernoma is a rare slow-growing tumor originating from brown adipose tissue. Due to its rarity, only a few case reports have been published so far. Pelvic localization is anedoctal and preoperative differential diagnosis with other malignancies may be challenging. We present the case of a woman who, due to a lower abdominal pain, underwent an abdominal ultrasonography with diagnosis of a 15 cm hyperechogenous pelvic mass. A subsequent MRI showed a 16 × 5.8 × 7.8 cm3 lesion anterior to the left iliacus muscle, with an intra- and extrapelvic component longitudinally extending from the left anterior superior iliac spine until the lesser trochanter. Surgical resection was performed and final histopathology was consistent with hibernoma. This report emphasizes the necessity to include hibernoma among differential diagnosis when a retroperitoneal abdominal mass is diagnosed and the difficulty to perform preoperatively this diagnosis due to the extreme rarity of these neoplasms.

Three patients who developed hypothyroidism after x irradiation to the neck are presented. The first two cases demonstrate that patients can develop clinical and chemical hypothyroidism after a very short interval following radiotherapy. Hypothyroidism developed in the first patient in the absence of surgical manipulation of the neck, or a large iodine load 4 months after receiving 6800 rad of x-ray therapy to his neck for carcinoma of the larynx. The second patient developed hypothyroidism approximately 6 months after his radiotherapy for carcinoma of the esophagus. Both of these patients demonstrated high titers of serum antithyroid antibodies. A third patientmore » with Hodgkin's disease did not manifest clinical symptoms and signs of hypothyroidism until 6 years after radiation therapy. These cases demonstrate the variability of onset of hypothyroidism after radiotherapy and emphasize the need for careful evaluation of thyroid function before and after neck irradiation.« less

Phobic postural vertigo treated with autogenic training: a case report

2008-01-01

Background Patients suffering from dizziness due to vertigo are commonly encountered in the department of otolaryngology. If various clinical examinations do not reveal any objective findings, then the patients are referred to the department of internal medicine or psychiatry. In many cases, the diagnosis is psychological dizziness. Phobic postural vertigo, which was first reported by Brandt T et al in 1994, is supposed to be a type of psychological dizziness. The diagnosis is based on 6 characteristics proposed by Brandt et al. Patients are usually treated with conventional medical therapy, but some cases may be refractory to such a therapy. Psychotherapy is recommended in some cases; however, psychotherapy including autogenic training, which can be used for general relaxation, is not widely accepted. This paper describes the successful administration of autogenic training in a patient suffering from phobic postural vertigo. Case presentation We present a case of a patient who suffered from phobic postural vertigo. A 37-year-old female complained of dizziness. She had started experiencing dizziness almost 3 years She was intractable to many sort of conventional therapy. In the end, her symptom disappeared after introduction of autogenic training. Conclusion Autogenic training can be a viable and acceptable treatment option for phobic postural vertigo patients who fail to respond to other therapies. This case emphasizes the importance of autogenic training as a method to control symptom of phobic postural vertigo. PMID:18826607

The current ubiquity of functional neuroimaging studies, and the importance they have had in elucidating brain function, obscures the fact that much of what we know about brain-behavior relationships derives largely from the study of single- and multiple-patient cases. A major goal of the present review is to describe how single cases continue to uniquely and critically contribute to cognitive neuroscience theory. With several recent examples from the literature, we demonstrate that single cases can both challenge accepted dogma and generate hypotheses and theories that steer the field in new directions. We discuss recent findings from case studies that specify critical functions of the hippocampus in episodic memory and recollection, and clarify its role in nonmnemonic abilities. Although we focus on the hippocampus, we discuss other regions and the occurrence of new associative learning, as well as the involvement of the ventromedial prefrontal and parietal cortices in memory encoding and retrieval. We also describe ways of dealing with the shortcomings of case studies, and emphasize the partnership of patient and neuroimaging methods in constraining neurocognitive models of memory. © 2014 New York Academy of Sciences.

Juvenile xanthogranuloma (JXG) is a benign histiocytic skin disorder mainly encountered during infancy and childhood. Although with multiple potential localizations, less than 1% of the cases exhibit ocular manifestations. Some of these might lead to serious complications, specifically, secondary glaucoma that can result in severe and blinding eye disease. The aim of the present case report was to demonstrate typical clinical features, emphasize the difficulties attributed when managing these patients and literature review. We present the case of 4 months old female baby with spontaneous hyphema and secondary unilateral glaucoma due to ocular JXG. The natural history and treatment of the condition were extremely difficult to handle due to multiple opinions in histopathology related to other severe conditions that resembled with the lesions detected in this case: myelomonocytic leukemia and Langerhans cell histiocytosis. Although a minority of patients with JXG have ocular involvement, recognition of this condition is important because a treatment delay can lead to serious complications, such as glaucoma and spontaneous hyphema, as in our case. A thorough differential diagnosis represents the key to a proper management plan in these patients, both on short and long term. "Triple disease" defined as JXG plus neurofibromatosis type 1 (NF-1) and juvenile chronic myelogenous leukemia (JCML) has been reported, but it was not confirmed in our patient.

Button battery lodged in the esophagus carries a high risk of morbidity and mortality. The purpose of this study was to present cases of patients with esophageal button battery ingestion treated at our clinic and to emphasize the importance of early diagnosis and treatment. Records of patients admitted to our hospital for foreign body ingestion between January 2010 and May 2015 were retrospectively reviewed. Cases with button battery lodged in the esophagus were included in the study. Patient data regarding age, sex, length of time after ingestion until admission, presenting clinical symptoms, type and localization of the battery, management, and prognosis were analyzed. Among 1891 foreign body ingestions, 71 were localized in the esophagus, and 8 of those (11.2%) were cases of button battery ingestion. Mean age was 1.7 years. Admission was within 6 hours of ingestion in 5 cases, after 24 hours had elapsed in 2, and 1 month after ingestion in 1 case. All patients but 1 knew the history of ingestion. Prompt endoscopic removal was performed for all patients. Three patients developed esophageal stricture, which responded to dilatation. Early recognition and timely endoscopic removal is mandatory in esophageal button battery ingestion. It should be suspected in the differential diagnosis of patients with persistent respiratory and gastrointestinal symptoms.

Gorlin-Goltz Syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS), is an autosomal dominant trait caused due to mutations in the patched tumor suppressor gene (PTCH) gene found on the long arm of chromosome 9. The syndrome is characterized by the presence of odontogenic keratocysts (OKCs), basal cell carcinomas, and skeletal malformations. Early diagnosis of the syndrome can be done by pedodontist as OKC is one of the early manifestations of the syndrome. Early diagnosis and treatment is important for long-term prognosis of the syndrome by reducing the severity of cutaneous carcinomas and deformities due to jaw cyst. The present case describes an 11-year-old patient with some typical features of NBCCS, which were diagnosed through its oral and maxillofacial manifestations. This case emphasizes the importance of pedodontist in early recognition of the syndrome. Tandon S, Chauhan Y, Sharma M, Jain M. Gorlin-Goltz Syndrome: A Rare Case Report of a 11-Year-Old Child.

Tuberculosis, a contagious bacterial disease which is caused by Mycobacterium tuberculosis, primarily involves the lungs.Though Pulmonary tuberculosis (PTB) is the commonest clinical presentation, there is a need for alertness towards uncommon presentations which involve other organs. Tuberculous otitis media (TOM) is one such rare presentation seen in paediatric practice. It is characterized by painless otorrhoea which fails to respond to the routine antibacterial treatment. TOM usually occurs secondary to PTB. Here is a case of tuberculous otitis media with Proteus mirabilis co-infection, with no evidence of PTB. In the sample of ear discharge obtained from the patient, acid fast bacilli were demonstrated on direct microscopy after Ziehl-Neelsen staining. Culture done on Lowenstein-Jensen medium demonstrated slow-growing Mycobacterium. Bacteriological culture and identification helped in isolating Proteus mirabilis. PCR, followed by Line- Probe Assay for early identification and susceptibility testing to primary drugs, was done. Further, patient tested negative for the Mantoux test. Patient was enrolled in National Tuberculosis programme- RNTCP. This case emphasizes on one of the less common presentations of a common disease. A high clinical suspicion and laboratory confirmation are required for appropriate patient management.

The authors present a case report of a patient who was treated by a case manager, a member of a Croatian Community Mental Health (CMH) Team, following the recommendations of WHO 2004 as well as the IRIS guidelines and the Basic Standards for Management of Patients with Serious Mental Illness in the Community (Agius 2005) and using the elements of Clinical case management (Muser 1998), Assertive community treatment model (Burns 1995, Scott 1995, Wolfsan 1990), the personal strength model (Rapp 1988) and Rehabilitation model (Anthony 1993). In order to emphasize the importance of the therapist-patient relationship in the treatment of chronic schizophrenic patients (Ivezic 2001) and creating the group atmosphere a Croatian model of case management is created where the patient's needs and risks are assessed by a multidisciplinary team which also conducts the recommended psychosocial interventions plan. The majority of interventions are conducted in groups. The case manager develops a confident relationship with a patient, nourishes the positive transference and aids the delivery of the treatment. The main goals of the interventions are empowerment of the patient, improvement of his abilities and decreasing of disabilities. The case manager also carries out a full assessment of the needs of the patient's family so that the family or carers are also included in the treatment or support if necessary (Gruber 2006). A case report of a patient and the work of her case manager as well as the case manager's diary (Gruber 2007) and the Croatian model of case management is presented in this article.

The present paper highlights the importance of diagnostic criteria and histopathology in early and prompt diagnosis which will lead to proper treatment and genetic counseling of the patient. Discussion. Gorlin-Goltz syndrome is about multisystem process comprising the triad of basal cell nevi, jaw keratocysts, and skeletal anomalies. A spectrum of other neurological, ophthalmic, endocrine and genital manifestations is known to be variably associated with this triad. Diagnosis of the syndrome is based on major and minor criteria. Conclusion. This paper emphasizes the importance of oral and maxillofacial health professionals in the early diagnosis of nevoid basal cell carcinoma syndrome and in a preventive multidisciplinary approach to provide a better prognosis to the patient.

A case of laryngeal myasthenia gravis in a 65-year-old woman presenting with hoarseness as the sole symptom is reported. Voice spectrography was performed before and after injection of intravenous edrophonium. There was a marked improvement in the patient's voice after the administration of edrophonium, which was confirmed by the changes seen on the sound spectrogram. This was the only objective indication of a diagnosis of myasthenia gravis. No thymoma was seen on chest X-ray and the patient was negative for anti-acetylcholine receptor antibodies. Treatment for laryngeal myasthenia gravis was initiated and the patient's vocal problems resolved. This case emphasizes the need to consider systemic diseases in the differential diagnosis of hoarseness and demonstrates the need for careful follow-up in such patients.

Vaginal discharge in young prepubertal girls is a common problem in clinical practice. No specific infective pathogen is identified in most of the children. The reported common microbes include group A beta-hemolytic streptococci, Haemophilus influenzae and some Gram-negative bacilli. Sexually transmitted pathogens such as Neisseria gonorrhoeae and Chlamydia trachomatis are important causes of vulvovaginitis in children suffering from sexual abuse. We report two cases of prepubertal vulvovaginitis presenting with profuse purulent vaginal discharge, and H. influenzae and N. gonorrhoeae identified respectively. Both girls denied any sexual exposure and there was no evidence of sexual abuse. They responded well to antibiotic treatment, and no symptoms recurred in the following months. We would like to emphasize the defined etiology of childhood vulvovaginitis and appropriate treatment, in addition to gynecological evaluation for evidence of sexual abuse.

Laypeople use expert opinion as a mental shortcut to form views on complex scientific issues. This heuristic is particularly relevant in the case of climate change, where perception of consensus is one of the main predictors of public support for climate action. A low public perception of consensus (around 60% compared to the actual 97% consensus) is a significant stumbling block to meaningful climate action, underscoring the importance of closing the "consensus gap". However, some scientists question the efficacy or appropriateness of emphasizing consensus in climate communication. I'll summarize the social science research examining the importance and effectiveness of consensus messaging. I'll also present several case studies of consensus messaging employed by the team of communicators at the Skeptical Science website.

Methylphenidate is a short-acting stimulant. In this article, the authors report a 7-year-old male patient who presented with orofacial and limb dyskinesia after his first dose of methylphenidate treatment for a diagnosis of attention-deficit/hyperactivity disorder; he was also receiving sodium valproate treatment for epilepsy. Orofacial dyskinesia appeared 5 hours after methylphenidate administration, persisted for 10 hours, and had completely resolved within 2 days. Although limb dyskinesia after methylphenidate is a commonly reported side effect, to the authors' knowledge this is only the second reported case to develop both orofacial and limb dyskinesia in the acute period after the first dose of methylphenidate. This case is reported to emphasize the potential side effects of methylphenidate, individual differences in drug sensitivities, and drug-receptor interactions via different mechanisms.

Nutritional rickets remains a significant public health issue for children worldwide. Although it has almost disappeared in industrialized countries following routine vitamin D supplementation, recent evidence suggests an increasing incidence, especially in young children. In addition to the classical clinical consequences on bone and the growth plate, rickets may also be associated with life-threatening neurological and cardiac complications in the most severe forms. Consequently, early screening and treatment are required. Here, we report the case of a 2-year-old child who presented with severe nutritional rickets associated with seizure and cardiomyopathy. Family screening revealed rickets in all the siblings. This case report emphasizes the importance of being aware of this disease, notably in population with sociocultural risk factors.

Child abuse is a sensitive topic among many medical practitioners and the diagnosis of this entity requires awareness about conditions which can mimic physical child abuse. Here, the authors present a case of a 13-year-old school non-attendee who was referred due to multiple scars, over areas prone to accidental as well as non-accidental injury, who underwent medicolegal examination due to suspicion of physical child abuse. On further inquiry, it was discovered that she had easy bruising and poor wound healing. A diagnosis of Ehlers-Danlos syndrome was established and physical child abuse was excluded. This case emphasizes the importance of identifying conditions which may confound the diagnosis of physical child abuse. This is of utmost importance in avoiding adverse legal and psycho-social implications on the child, family and society.

Genetically targeted therapies for rare Mendelian conditions are improving patient outcomes. Here, we present the case of a 20-mo-old female suffering from a rapidly progressing neurological disorder. Although diagnosed initially with a possible autoimmune condition, analysis of the child's exome resulted in a diagnosis of Brown–Vialetto–Van Laere syndrome 2 (BVVLS2). This new diagnosis led to a change in the therapy plan from steroids and precautionary chemotherapy to high-dose riboflavin. Improvements were reported quickly, including in motor strength after 1 mo. In this case, the correct diagnosis and appropriate treatment would have been unlikely in the absence of exome sequencing and careful interpretation. This experience adds to a growing list of examples that emphasize the importance of early genome-wide diagnostics. PMID:27148561

2013-01-01

THE CONCEPT OF FIBROOSSEOUS LESIONS OF BONE HAS EVOLVED OVER THE LAST SEVERAL DECADES AND NOW INCLUDES TWO MAJOR ENTITIES: fibrous dysplasia and ossifying fibroma. Peripheral cemento-ossifying fibroma is a relatively rare tumour classified between fibroosseous lesions. It predominantly affects adolescents and young adults, with peak prevalence between 10 and 19 yrs. The cemento-ossifying fibroma is a central neoplasm of bone as well as periodontium which has caused considerable controversy because of confusion regarding terminology and the criteria for its diagnosis. The cemento-ossifying fibroma is odontogenic in origin, whereas ossifying fibroma is of bony origin. Lesions histologically similar to peripheral ossifying fibroma have been given various names in existing literature. Therefore, we present and discuss in this paper a series of cases of peripheral cemento-ossifying fibroma emphasizing the differential diagnosis.

Segrè, Daniel; Marx, Christopher J.

2010-06-01

The perturbation of a gene in an organism's genome often causes changes in the organism's observable properties or phenotypes. It is not obvious a priori whether the simultaneous perturbation of two genes produces a phenotypic change that is easily predictable from the changes caused by individual perturbations. In fact, this is often not the case: the nonlinearity and interdependence between genetic variants in determining phenotypes, also known as epistasis, is a prevalent phenomenon in biological systems. This focus issue presents recent developments in the study of epistasis and genetic interactions, emphasizing the broad implications of this phenomenon in evolutionary biology, functional genomics, and human diseases.

Neurocutaneous melanosis (NCM) is a rare, congenital non-hereditary syndrome, characterized by multiple pigmented nevi. We report the radiologic findings of a newborn who had extensive cutaneous melanotic nevus with satellite lesions in the brain. Ultrasound showed multiple echogenic foci in the cerebral parenchyma. Subsequent MRI confirmed these lesions as characteristic deposits of melanin. The infant was asymptomatic, but presence of risk factors such as malign transformation or neurological manifestations makes early diagnosis very important. We present this case to emphasize on the radiological findings of this syndrome in order to reach an early diagnosis. PMID:25780540

Fracture of the penis: an atypical presentation.

Waseem, Muhammad; Upadhyay, Ruchi; Kapoor, Ramnath; Agyare, Samuel

2013-08-13

Fracture of the penis is an uncommon injury presenting to the emergency department (ED). Personal embarrassment and social scenarios associated with this condition may result in underreporting. Patients often delay seeking medical attention, and even when they do, as in our case report, they may withhold the condition for a significant time. ED physicians need to be aware of the social inhibitions and the need for early diagnosis and prompt treatment. A delay in treatment increases the risk of complications such as ischemia, necrosis and penile deformity.Fracture of the penis is caused by rupture of the tunica albuginea of one or both corpora cavernosa by a blunt trauma to the erect penis. Diagnosis is usually clinical as evident by the characteristic history and clinical presentation. Diagnostic modalities aid in the management of the fracture and associated injuries if present. But promptness in the recognition and initiation of treatment can significantly reduce the chances of post-injury complications. We present a case of penile fracture in a young male who presented to the ED with abdominal pain, but careful history and physical examination revealed penile fracture. A delay in diagnosis could have led to complications. Our case report is an attempt to emphasize the need to suspect injury to the penis in a young adult who might present to the emergency department with an entirely different complaint and also to treat any penile trauma as an emergency. This report provides evidence of an uncommon and underreported clinical entity. A review of the pertinent literature is included.

Fluid Mechanics: The Pamphlet

Variano, Evan

2012-11-01

One impediment to student learning in introductory fluid mechanics courses is that the fundamental laws of physics can become lost in the ``noise'' of dozens of semi-empirical equations describing special cases. This can be exacerbated by trends in textbooks and other teaching media. This talk will explore a minimalist approach, whereby the entire content of introductory fluids is distilled to a single 1-page pamphlet, designed to emphasize the governing equations and their near-universal applicability. We are particularly interested in hearing feedback from the audience on ways to further distill the content while keeping it accessible and useful. To further emphasize the difference between the fundamental laws and the many specific cases, we have begun assembling a complementary resource: a field guide to fluid phenomena, which mixes the approach of Van Dyke's book with a standard field guide. This is designed to emphasize that there is a ``zoology'' of fluid phenomena, to which the same small set of fundamental laws has been applied repeatedly. These materials may be useful in helping AP Physics teachers cover fluid mechanics, which is an under-utilized opportunity to introduce young scientists to our field of study.

Advertising energy saving programs: The potential environmental cost of emphasizing monetary savings.

Many consumers have monetary or environmental motivations for saving energy. Indeed, saving energy produces both monetary benefits, by reducing energy bills, and environmental benefits, by reducing carbon footprints. We examined how consumers' willingness and reasons to enroll in energy-savings programs are affected by whether advertisements emphasize monetary benefits, environmental benefits, or both. From a normative perspective, having 2 noteworthy kinds of benefit should not decrease a program's attractiveness. In contrast, psychological research suggests that adding external incentives to an intrinsically motivating task may backfire. To date, however, it remains unclear whether this is the case when both extrinsic and intrinsic motivations are inherent to the task, as with energy savings, and whether removing explicit mention of extrinsic motivation will reduce its importance. We found that emphasizing a program's monetary benefits reduced participants' willingness to enroll. In addition, participants' explanations about enrollment revealed less attention to environmental concerns when programs emphasized monetary savings, even when environmental savings were also emphasized. We found equal attention to monetary motivations in all conditions, revealing an asymmetric attention to monetary and environmental motives. These results also provide practical guidance regarding the positioning of energy-saving programs: emphasize intrinsic benefits; the extrinsic ones may speak for themselves.

2015-12-01

Well rounded scientific researchers are not only experts in their field, but can also communicate their work to a multitude of various audiences, including the general public and undergraduate university students. Training in these areas should ideally start during graduate school, but many programs are not preparing students to effectively communicate their work. Here, we present results from the NSF-funded CASE (Changing Alaska Science Education) program, which was funded by NSF under the auspices of the GK-12 program. CASE placed science graduate students (fellows) in K-12 classrooms to teach alongside of K-12 teachers with the goal of enhancing communication and teaching skills among graduate students. CASE trained fellows in inquiry-based and experiential techniques and emphasized the integration of art, writing, and traditional Alaska Native knowledge in the classroom. Such techniques are especially effective in engaging students from underrepresented groups. As a result of participation, many CASE fellows have reported increased skills in communication and teaching, as well as in time management. These skills may prove directly applicable to higher education when teaching undergraduate students.

Scrub typhus and malaria can involve multiple organ systems and are notoriously known for varied presentations. However, clinical malaria or scrub typhus is unusual without fever. On the other hand, altered sensorium with or without fever, dehydration, hemorrhage and hemolysis may lead to low blood pressure. Presence of toxic granules and elevated band forms in such patients can even mimic sepsis. When such a patient is in the peripartum period, it creates a strong clinical dilemma for the physician especially in unbooked obstetric cases. We present such a case where a 26-year-old unbooked female presented on second postpartum day with severe anemia, altered sensorium, difficulty in breathing along with jaundice and gum bleeding without history of fever. Rapid diagnostic test for malaria was negative and no eschar was seen. These parameters suggested a diagnosis of HELLP (Hemolysis, Elevated Liver enzymes, Low Platelet) syndrome with or without puerperal sepsis. Subsequently she was diagnosed as having asymptomatic malaria and scrub typhus and responded to the treatment of it. The biochemical changes suggestive of HELLP syndrome also subsided. We present this case to emphasize the fact that mere absence of fever and eschar does not rule out scrub typhus. It should also be considered as a differential diagnosis in patients with symptoms and signs suggesting HELLP syndrome. Asymptomatic malaria can complicate case scenario towards puerperal sepsis by giving false toxic granules and band form in such situations.

Paracentric Inversion of Chromosome 21 Leading to Disruption of the HLCS Gene in a Family with Holocarboxylase Synthetase Deficiency.

2017-01-01

Holocarboxylase synthetase (HLCS) deficiency is a rare autosomal recessive disorder that presents with multiple life-threatening metabolic derangements including metabolic acidosis, ketosis, and hyperammonemia. A majority of HLCS deficiency patients respond to biotin therapy; however, some patients show only a partial or no response to biotin therapy. Here, we report a neonatal presentation of HLCS deficiency with partial response to biotin therapy. Sequencing of HLCS showed a novel heterozygous mutation in exon 5, c.996G>C (p.Gln332His), which likely abolishes the normal intron 6 splice donor site. Cytogenetic analysis revealed that the defect of the other allele is a paracentric inversion on chromosome 21 that disrupts HLCS. This case illustrates that in addition to facilitating necessary family testing, a molecular diagnosis can optimize management by providing a better explanation of the enzyme's underlying defect. It also emphasizes the potential benefit of a karyotype in cases in which molecular genetic testing fails to provide an explanation.

Cannabinoid hyperemesis syndrome masquerading as an eating disorder.

PubMed

Brewerton, Timothy D; Anderson, Odette

2016-08-01

The case of a 22 year old woman with cannabinoid hyperemesis syndrome (CHS) presenting as an eating disorder is described. The importance of recognizing chronic cannabis use as a cause of episodic vomiting is emphasized, given that CHS can be confused with self-induced purging and cyclic vomiting. This case was further complicated by the well-defined history of anorexia nervosa (binge-purge type), major depressive disorder, obsessive-compulsive disorder, migraine headache, and the initial denial of cannabis use. However, collateral history and a positive drug screen confirmed the diagnosis. The signs, symptoms and pathophysiological mechanisms of CHS are reviewed in light of clinical presentations that mimic eating disorder phenomenology complicated by addiction. Given the trend for increasing legalization of recreational marijuana as well as medical marijuana, CHS is an important and potentially complicating disorder that eating disorder clinicians need to be aware of. © 2016 Wiley Periodicals, Inc.

Borderline personality disorder (BPD) is a diagnosis defined by impairments in several dynamic processes (e.g., interpersonal relating, affect regulation, behavioral control). Theories of BPD emphasize that these impairments appear in specific contexts, and emerging results confirm this view. At the same time, BPD is a complex construct that encompasses individuals with heterogeneous pathology. These features—dynamic processes, situational specificity, and individual heterogeneity—pose significant assessment challenges. In the current study, we demonstrate assessment and analytic methods that capture both between-person differences and within-person changes over time. Twenty-five participants diagnosed with BPD completed event-contingent, ambulatory assessment protocols over 21 days. We used p-technique factor analyses to identify person-specific psychological structures consistent with clinical theories of personality. Five exemplar cases are selected and presented in detail to showcase the potential utility of these methods. The presented cases' factor structures reflect not only heterogeneity but also suggest points of convergence. The factors also demonstrated significant associations with important clinical targets (self-harm, interpersonal violence). PMID:27317561

The renewed interest in mycology has been reflected in growing use of wild mushrooms in culinary, driven by its nutritional, organoleptic and commercial value. However, the international scientific literature describes several syndromes of poisoning by mushrooms. We live, therefore, a paradigm conducive to an increase of mycetism, whose diagnosis requires a high level of suspicion and knowledge of clinical profiles. In Portugal, the real dimension of this problem is unknown. Although some mycetisms, such as the hepatotoxic syndrome, have high morbidity and mortality, their relative incidences are unknown. Add up to the shortage of international scientific literature, often outdated and inappropriate to clinical practice. In this context, this article provides an updated epidemiological and clinical perspective emphasizing a narrative and descriptive information on the forms of presentation, differential diagnosis and therapeutic approach, with the ultimate goal of the elaboration of a national diagram-oriented approach to decision-making diagnosis. We analyzed all the clinical records of patients admitted into ten hospitals between 1990 and 2008, notified with the code 988.1 of GDH (acute poisoning by mushrooms). There were registered demographic data, way of presentation, time between ingestion and onset of symptoms, the annual distribution, clinical profile, clinical and analytical treatment performed and complications. We identified 93 cases of acute poisoning by mushrooms, with equal gender distribution and inclusion of individuals of all age groups (from 1 to 85 years), but with greater representation from 21 to 50 years. There was a bimodal seasonal pattern, with a higher peak between September and December and a second in the spring. The hepatotoxic profile presentation corresponded to 63.4% and 31.7% of the cases to gastroenteritis syndrome. The mortality in cases of hepatotoxicity was 11.8%. The developmental profile of the rate of prothrombin time (PT), aspartate aminotransferase (AST) and bilirubin, was an important setting for diagnosis and prognosis. TGO increases early, always within 48 hours, having an essential role in the diagnosis of hepatotoxicity. Despite the late elevation of bilirubin, the cases of death revealed that there was an earlier increase, reaching higher values, which seems to have a prognostic value, to be evaluated with further studies. Finally, we propose a diagram of diagnostic performance, considerating the generalized lack of mycological diagnosis in Portugal, which emphasizes the need for a careful history, focused on quantifying the latency period.

The Use of Invisalign® System in the Management of the Orthodontic Treatment before and after Class III Surgical Approach

PubMed Central

2016-01-01

The approach to skeletal dysmorphisms in the maxillofacial area usually requires an orthodontic treatment by means of fixed appliances, both before and after the surgical phase. Since its introduction, Invisalign system has become a popular treatment choice for the clinicians because of the aesthetics and comfort of the removable clear aligners compared with the traditional appliances. Therefore, the aim of the present report was to illustrate the management of a malocclusion by means of Invisalign system associated with the traditional surgical technique. The present paper shows a case of a 23-year-old male patient characterized by a Class III malocclusion with lateral deviation of the mandible to the left side and cross-bite on teeth 2.2, 2.3, and 2.4. Invisalign system was used during the pre- and postsurgical phases rather than fixed appliances. The posttreatment cephalometric analysis emphasized the stability of the dental and skeletal symmetry corrections, occlusion and functional balance, over a 6-year follow-up. The results achieved at the end of the treatment showed how Invisalign can be effective in the management of the orthodontic phases in orthognathic surgery. The follow-up after 6 years emphasizes the stability of the treatment over time. PMID:27429811

Three cases of familial unilateral gluteal hypoplasia are reported. The index case in addition to having gluteal hypoplasia also has unilateral pectoral muscle hypoplasia. Another relative has unilateral symbrachydactyly of the distal phalanges of one foot. All four affected individuals in our pedigree were female. We propose that our cases are best classified as part of the Poland complex of anomalies. Our cases emphasize that intrafamilial phenotypic heterogeneity is possible within the Poland complex.

Lymph node lesions in infectious mononucleosis (IM) show a marked histologic diversity. We report here three cases of IM lymphadenitis with histologic findings indistinguishable from those of toxoplasmic lymphadenitis. The histologic findings of the three cases presented here showed a histologic triad of toxoplasmic lymphadenitis, including (i) numerous lymphoid follicles with hyperplastic germinal centers; (ii) small clusters or single epithelioid histiocytes; and (iii) multiple foci of monocytoid B-cells. Moreover, all three lesions contained isolated or small clusters of epithelioid histiocytes within the hyperplastic germinal centers and the periphery of lymphoid follicles, which are the most specific histologic findings of toxoplasmic lymphadenitis. However, serologic findings confirmed EBV infection in all three cases. On in situ hybridization, numerous Epstein-Barr virus (EBV)-encoded small RNA (EBER)-positive cells were demonstrated in the germinal center, as well as in interfollicular areas in all three cases. Toxoplasmosis gondii infection was excluded in at least one case, based on serologic findings. Polymerase chain reaction analysis also demonstrated that there was no T. gondii DNA in the remaining two cases. Two of our three cases showed atypical clinical presentations, including an absence of atypical lymphocytosis in peripheral blood in two cases, age more than 30 years, and an absence of systemic symptoms in one case. It appears that previous descriptions emphasize the differential diagnostic problems between IM lymphadenitis and malignant lymphomas. However, from a therapeutic perspective, it is important to discriminate IM lymphadenitis from toxoplasmic lymphadenitis particularly in patients showing atypical clinical features. 2010 Elsevier GmbH.

A 68-year old male presenting with rhabdomyolysis-associated acute kidney injury following concomitant use of elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate and pravastatin/fenofibrate: a case report.

We present what we believe to be the first case in the literature of rhabdomyolysis-induced renal failure caused by a probable drug interaction between elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (EVG/COBI/FTC/TDF) and pravastatin/fenofibrate. A 68-year old Caucasian man presented with progressive pain in both legs two weeks after commencing treatment with EVG/COBI/FTC/TDF. He was found to have biochemical evidence of rhabdomyolysis and acute renal failure. We emphasize the need for post marketing surveillance of adverse effects of new products. Pharmacokinetic studies are necessary to investigate the levels of pravastatin in patients taking COBI and fenofibrate with and without other comorbidities. Meanwhile, we suggest that creatine kinase levels should be monitored and patients advised to report myalgias when using concomitant EVG/COBI/FTC/TDF and pravastatin/fenofibrate. This case serves as an important reminder to use estimated glomerular filtration rates rather than serum creatinine levels when choosing new medications. If potentially nephrotoxic combinations are started in patients with borderline estimated glomerular filtration rates, it may be prudent to check these filtration rates more frequently than usual. In patients with reduced estimated glomerular filtration rates, potentially nephrotoxic combinations should be avoided wherever possible.

Sinonasal Globular Amyloidosis Simulating Malignancy: A Rare Presentation.

Primary localized amyloidosis in the head and neck region is a rare entity. The most commonly involved organ is larynx. Primary amyloidosis localized to the sinonasal tract is extremely rare. We report one such case along with a brief review of the associated literature. The aim of reporting this case is to emphasize the fact that sometimes nasal amyloidosis can also present with signs and symptoms of nasal and nasopharyngeal malignancy. The definitive diagnosis in such cases depends upon histopathology and further confirmed by immunohistochemistry. A 55-year old male presented with recurrent episodes of nasal bleed, bilateral nasal obstruction, and bilateral hearing loss from last 7 years. On clinical examination a mass was found in the nasal cavity on both sides reaching up to the nasopharynx. Contrast enhanced CT scan revealed that the mass was extending up to the skull base and destroying bony landmarks of the nasal cavity and paranasal sinuses. Mass was proved to be amyloidosis after histopathological examination. It showed multiple blotches of globular submucosal deposit of amyloid, on staining with Congo red. Immunohistochemistry confirmed AL amyloidosis with expression of mixed kappa and lambda light chain immunoglobulin (κ > λ). No evidence of systemic amyloidosis was found after proper work up. It was managed by conservative surgery.

Fanconi syndrome and severe polyuria: an uncommon clinicobiological presentation of a Gitelman syndrome

PubMed Central

2014-01-01

Background Gitelman syndrome is an autosomal recessive tubulopathy characterized by hypokalemia, hypomagnesemia, metabolic alkalosis and hypocalciuria. The majority of patients do not present with symptoms until late childhood or adulthood, and the symptoms are generally mild. We report here the first case of Gitelman syndrome presenting with the biological features of Fanconi syndrome and an early polyuria since the neonatal period. We discuss in this article the atypical electrolytes losses found in our patient, as well as the possible mechanisms of severe polyuria. Case presentation A 6-year-old Caucasian girl was admitted via the Emergency department for vomiting, and initial laboratory investigations found hyponatremia, hypokalemia, metabolic acidosis with normal anion gap, hypophosphatemia, and hypouricemia. Urinalysis revealed Na, K, Ph and uric acid losses. Thus, the initial biological profile was in favor of a proximal tubular defect. However, etiological investigations were inconclusive and the patient was discharged with potassium chloride and phosphorus supplementation. Three weeks later, further laboratory analysis indicated persistent hypokalemia, a metabolic alkalosis, hypomagnesemia, and hypocalciuria. We therefore sequenced the SLC12A3 gene and found a compound heterozygosity for 2 known missense mutations. Conclusions Gitelman syndrome can have varying and sometimes atypical presentations, and should be suspected in case of hypokalemic tubular disorders that do not belong to any obvious syndromic entity. In this case, the proximal tubular dysfunction could be secondary to the severe hypokalemia. This report emphasizes the need for clinicians to repeat laboratory tests in undiagnosed tubular disorders, especially not during decompensation episodes. PMID:25112827

History and clinical findings  We elaborate the case of a 72-year-old patient who presented with a painful swelling of the lower jaw in the emergency unit. Investigations and diagnosis  In the clinical examination and the CT scan, a widespread cervical emphysema was found which raised suspicion for the presence of a necrotizing fasciitis of the head and neck due to aerogenic infection. Close spatial vicinity to the teeth of the left upper and lower jaw was present, so that the necrotizing fasciitis was assumed to be odontogenic. Treatment and course  Based on the clinical presentation and the imaging findings the diagnosis of necrotizing fasciitis in the sense of a possible infection with gas building bacteria accompanying with an infection of the mediastinum was made. Immediately performed therapy included sternotomy and extended surgical debridement of necrosis. Conclusion  The presented case emphasizes that necrotizing fasciitis due to gas-producing infections should be considered as a differential diagnosis for cervical soft tissue emphysema for which an odontogenic focus is the most common cause. Rapid diagnosis is essential for successful treatment consisting of immediate surgical debridement and intravenous antibiotics. © Georg Thieme Verlag KG Stuttgart · New York.

Disclosing harmful medical errors to patients: tackling three tough cases.

PubMed

Gallagher, Thomas H; Bell, Sigall K; Smith, Kelly M; Mello, Michelle M; McDonald, Timothy B

2009-09-01

A gap exists between recommendations to disclose errors to patients and current practice. This gap may reflect important, yet unanswered questions about implementing disclosure principles. We explore some of these unanswered questions by presenting three real cases that pose challenging disclosure dilemmas. The first case involves a pancreas transplant that failed due to the pancreas graft being discarded, an error that was not disclosed partly because the family did not ask clarifying questions. Relying on patient or family questions to determine the content of disclosure is problematic. We propose a standard of materiality that can help clinicians to decide what information to disclose. The second case involves a fatal diagnostic error that the patient's widower was unaware had happened. The error was not disclosed out of concern that disclosure would cause the widower more harm than good. This case highlights how institutions can overlook patients' and families' needs following errors and emphasizes that benevolent deception has little role in disclosure. Institutions should consider whether involving neutral third parties could make disclosures more patient centered. The third case presents an intraoperative cardiac arrest due to a large air embolism where uncertainty around the clinical event was high and complicated the disclosure. Uncertainty is common to many medical errors but should not deter open conversations with patients and families about what is and is not known about the event. Continued discussion within the medical profession about applying disclosure principles to real-world cases can help to better meet patients' and families' needs following medical errors.

Strange bedfellows in science teacher preparation: conflicting perspectives on social justice presented in a Teach For America—university partnership

2017-02-01

Teach For America (TFA), a widespread and well-known route into the teaching profession, frequently partners with university-based education programs to prepare and certify its corps members. However, university-based teacher education programs frequently emphasize very different understandings of socially just education and priorities for training teachers from those of TFA. Accordingly, science teachers trained through TFA-university partnerships encounter conflicting understandings of science education, justice, and urban communities as they are introduced to teaching practice. In this ethnographic case study we explored the experiences and reactions of a cohort of TFA corps members in a science methods course as they engaged with TFA's perspective focused primarily on enhancing students' social mobility and the methods course emphasizing democratic equality through scientific engagement. The study considers intersections between TFA's approach to teacher preparation and sociocultural perspectives on equitable science teaching. The study also lends insight into the contradictions and challenges through which TFA science teachers develop understandings about their role as science teachers, purposes and goals of science education, and identities of the students and communities they serve.

Nonvalvular atrial fibrillation is associated with a 4- to 5-fold strokes increase and may be responsible for 15% to 20% of all strokes in the elderly. In this scenario, the left atrial appendage thrombus would be the associated with 90% of cases. The use of anticoagulants, percutaneous devices, and the left atrial appendage surgical exclusion is still an open discussion. For left atrial appendage procedures, relevant anatomic spatial relationships have to be emphasized, besides the chance of the normal physiological functioning would be eliminated with the proceedings. There are evidences that the left atrial appendage closure during routine cardiac surgery is significantly associated with an increased risk of early postoperative atrial fibrillation. Therefore, the purpose of this review is to focus basic aspects for continuous medical education. In summary, the rationale of this text is to emphasize anatomical and pharmacological aspects involved in the simple surgical exclusion of left atrial appendage under cardiopulmonary bypass. There are several operative techniques, but to conclude this revision it will present one of them based on the discussed basic sciences. PMID:29267615

After successful introduction of anti-Haemophilus influenzae (Hi) serotype b vaccination program in Poland, invasive non-b or nontypeable H. influenzae infections have been reported more frequently alike in other countries all over the world. In this paper, we report 2 cases of H. influenzae serotype f (Hif) meningitis with severe clinical presentations which are rarely seen in previously healthy children.The first case is a 6-year-old girl who was admitted to pediatric ward with signs of meningitis. Laboratory tests confirmed bacteremic meningitis caused by Hif. The girl responded very well to administered treatment and recovered without any further complications. No underlying comorbidities were found. The second patient was a 4-year-old boy who, in course of Hif bacteremic meningitis, developed rapid septicemia and, despite aggressive treatment, died within a few hours of hospitalization. The child's past history was unremarkable.By presenting these cases, we would like to remind clinicians that invasive non-b Hi infections can become fatal not only in the group of the youngest children or children with coexisting comorbidities, as most commonly reported in the worldwide literature. At the same time, we want to emphasize the legitimacy of constant monitoring Hi epidemiology in order to take accurate actions if necessary.

Despite progress in laparoscopic surgery and increasing surgical experience, the incidence of bile duct injury during laparoscopic cholecystectomy fails to fall below 0.3%-0.6% and it is still higher than those recorded in the era of open cholecystectomy. Bile duct injuries belong to the most serious complications of abdominal surgery in general and often end up with liver transplantation as the only hope for cure. We present a case of a 78-year-old jaundiced male patient who sustained common hepatic duct injury during laparoscopic cholecystectomy eight months earlier. Exploratory laparotomy, ERCP and MRCP revealed a metal clip placed just below hepatic duct confluence and causing stricture of bile duct with dilatation of bile ducts proximal to the level of stenosis (Strasberg classification type E3 injury). Repair of the injury was performed by creating termino-lateral hepaticojejunostomy between the right and left hepatic ducts and retrocolic Roux en-Y jejunal limb. By presenting this case, we wish to emphasize the importance of timely conversion and execution of intraoperative cholangiography in all cases when identification of the structures of Calot’s triangle is not clear enough. Successful treatment of bile duct injury is only possible with joint approach of radiologist, gastroenterologist and experienced hepatobiliary surgeon.

To identify errors in forensic reports and to describe the characteristics of traumatic medico-legal cases presenting to the emergency department (ED) at a tertiary care hospital. This study is a retrospective cross-sectional study. The study includes cases resulting in a forensic report among all traumatic patients presenting to the ED of Adiyaman University Training and Research Hospital, Adiyaman, Turkey during a 1-year period. We recorded the demographic characteristics of all the cases, time of presentation to the ED, traumatic characteristics of medico-legal cases, forms of suicide attempt, suspected poisonous substance exposure, the result of follow-up and the type of forensic report. A total of 4300 traumatic medico-legal cases were included in the study and 72% of these cases were male. Traumatic medico-legal cases occurred at the greatest frequency in July (10.1%) and 28.9% of all cases occurred in summer. The most frequent causes of traumatic medico-legal cases in the ED were traffic accidents (43.4%), violent crime (30.5%), and suicide attempt (7.2%). The most common method of attempted suicide was drug intake (86.4%). 12.3% of traumatic medico-legal cases were hospitalized and 24.2% of those hospitalized were admitted to the orthopedics service. The most common error in forensic reports was the incomplete recording of the patient's "cooperation" status (82.7%). Additionally, external traumatic lesions were not defined in 62.4% of forensic reports. The majority of traumatic medico-legal cases were male age 18-44 years, the most common source of trauma was traffic accidents and in the summer months. When writing a forensic report, emergency physicians made mistakes in noting physical examination findings and identifying external traumatic lesions. Physicians should make sure that the traumatic medico-legal patients they treat have adequate documentation for reference during legal proceedings. The legal duties and responsibilities of physicians should be emphasized with in-service training.

The article is based on the case analysis of a sudden and unexpected intraoperative death of a 51-year-old female patient with hypertrophic cardiomyopathy, who was undergoing a non-cardiac operation in a non-cardiosurgery clinic, from acute precipitation of left ventricular outflow tract obstruction provoked by surgery and anesthesia. It emphasizes the importance of raising non-cardiac anesthesiologists' awareness of the issue and having clear standards of pre-operative evaluation and perioperative management of patients with hypertrophic cardiomyopathy in order to avoid fatal medical errors. A literature review on the disease with an accent on anesthesia-related issues is also given, and four standards of perioperative anesthetic management of patients with hypertrophic cardiomyopathy presenting for non-cardiac surgery in general hospital settings are developed and offered.

Myelodysplasia includes a group of developmental anomalies resulting from defects that occur during neural tube closure. Urological morbidity in patients with myelodysplasia is significant and if not treated appropriately in a timely manner can potentially lead to progressive renal failure, requiring dialysis or transplantation. We report the case of a 13-year old girl with neurogenic bladder who presented chronic renal failure secondary to lipomyelomeningocele with retethering of cord. She was managed with urinary indwelling catheterization until optimization of renal function and then underwent detethering of cord with excision and repair of residual lipomeningomyelocele. Her renal parameters improved gradually over weeks and then were managed on self clean intermittent catheterization. The case emphasizes the need for considering retethering of spinal cord in children with myelodysplasia where symptoms of neurogenic bladder and recurrent urinary tract infections occur.

2013-01-01

A rare case of combined Churg-Strauss syndrome (CSS) and allergic bronchopulmonary aspergillosis (ABPA) was presented. A 41-year-old woman was diagnosed with CSS based upon asthma, eosinophilia (23%), chest radiographic findings, paranasal sinusitis, peripheral neuropathy and positive p- anti-neutrophil cytoplasmic antibodies (pANCA). The diagnosis of ABPA was established on the pathological findings of allegic mucin impaction and fungal hyphae on lung biopsy. It was further proved by positive serum IgE and IgG antibodies specific to afumigatus. The clinical investigation features were reviewed in the patients with combined CSS and ABPA. All patients had the time sequence of the development of CSS after ABPA uniformly, suggesting immunopathogenesis involving the emergence of CSS. The role of lung biopsy in the diagnosis of the condition was emphasized. © 2012 Blackwell Publishing Ltd.

Two of the most common liver abscess is anamoebic liver abscess and pyogenic liver abscess (PLA). PLA could be as singular or multiple abscesses. It is usually caused by Klebsiella pneumonia and Escherichia coli. Historically, PLA is usually caused by acute appendicitis, but with developed of surgical practice and microbiology, the number of events has decreased. Here we present a case of a39-year-old woman that developed a PLA after she had an appendectomy about six months ago. An ultrasonogram and abdominal scan showed an abscess in the right lobe. We performed paracentesis, and the result from the pus culturewas positive for Escherichia coli with Extended-Spectrum Beta-Lactamase (ESBL) (+) that showed the same as the culture from lesion taken from her appendix. This report emphasizes the fact that, nowadays we still found Pyogenic liver abscess after peritonitis appendix perforation.

Challenges in the Management of Geriatric Trauma: A Case Report.

PubMed

Gaebel, Ashley; Keiser, Megan

This article describes geriatric trauma and commonly associated difficulties emphasizing both the epidemiology and assessment of geriatric trauma. There is little data guiding decisions for trauma patients 65 years or older, as there are many unique characteristics to the geriatric population, including comorbidities, medications, and the aging physiology. The geriatric population in the United States has been steadily climbing for the last 20 years and is projected to continue on this trend. Although each patient presents differently, there remains a need for the consistent utilization of standard guidelines to help dictate care for geriatric patients, particularly for patients not receiving care at a trauma center. This review uses a case study about an elderly woman with many comorbidities, followed by a comprehensive discussion of geriatric trauma and the challenges that result from a lack of guideline utilization to direct management.

Peripheral Cemento-Ossifying Fibroma: Case Series Literature Review

2013-01-01

The concept of fibroosseous lesions of bone has evolved over the last several decades and now includes two major entities: fibrous dysplasia and ossifying fibroma. Peripheral cemento-ossifying fibroma is a relatively rare tumour classified between fibroosseous lesions. It predominantly affects adolescents and young adults, with peak prevalence between 10 and 19 yrs. The cemento-ossifying fibroma is a central neoplasm of bone as well as periodontium which has caused considerable controversy because of confusion regarding terminology and the criteria for its diagnosis. The cemento-ossifying fibroma is odontogenic in origin, whereas ossifying fibroma is of bony origin. Lesions histologically similar to peripheral ossifying fibroma have been given various names in existing literature. Therefore, we present and discuss in this paper a series of cases of peripheral cemento-ossifying fibroma emphasizing the differential diagnosis. PMID:23365762

2013-01-01

Peripheral cemento-ossifying fibroma (PCOF) is a rare osteogenic neoplasm that ordinarily presents as an epulis-like growth. This is of a reactive rather than neoplastic nature and its pathogenesis is uncertain. PCOF predominantly affects adolescent and young adults with greatest prevalence around 28 years. We report here a rare clinical case of PCOF of the mandible, 1 cm mesiodistally and 1.5 cm occluso-gingivally in diameter, which caused difficulty in eating and speech, in a 42-year-old female patient. She was asymptomatic for 1 year and on follow-up for 6 mo post surgically showed gingival health and normal radioopacity of bone without any recurrence. Clinical, radiographic and histological characteristics are discussed and recommendations regarding differential diagnosis, treatment and follow up are provided. The controversial varied nomenclature and possible etiopathogenesis of PCOF are emphasized. PMID:24303483

2013-01-01

Encephalocraniocutaneous lipomatosis (ECCL), also known as Haberland syndrome, is a rare syndrome with unknown etiology. The syndrome is characterized by a triad of unique cutaneous, ocular, and central nervous system (CNS) manifestations. The cutaneous hallmark, nevus psiloliparus (NP), along with overlying alopecia is a constant feature. Choristoma of the eyelid is the most common ocular manifestation, while intracranial lipoma is the predominant CNS finding. Genetic counseling is required to emphasize that the disorder, although congenital, is not inheritable. We present a 21-year-old female with cutaneous, ocular, and CNS features satisfying the diagnostic criteria for ECCL. To our knowledge, this is the first case of ECCL having a large temporal exostosis. The objective of this article is to better understand the phenotypic spectrum of this syndrome whose molecular basis is still unknown. PMID:24604937

2017-03-13

The present paper discusses the lexical and grammatical peculiarities of English language medical case reports, taking into account their communicative purposes and intentions. The objective of the research is to clarify the principal mechanisms of producing an effective English language medical case report and thus to provide recommendations and guidelines for medical professionals who will deal with this genre. The analysis of medical case reports will largely focus on the most significant linguistic peculiarities, such as the use of active and passive voice, the choice of particular verb tenses, and pronouns. The selected medical case reports will be considered using methods of lexico-grammatical analysis, quantitative examination, and contextual, structural, narrative, and stylistic analyses. The research revealed a range of important stylistic features of medical case reports which markedly distinguish them from other genres of medical scientific writing: educational and instructive intentions, conciseness and brevity, direct and personal tone, and material presented in a narrative style. The present research has shown that the communicative strategies of the analyzed discourse, mentioned immediately above, are effectively implemented by means of specific lexical units and grammatical structures: the dominance of active voice sentences, past simple tense, personal pronouns, and modal verbs. The research has also detected the occasional use of the present perfect, present simple, and future simple tenses and passive voice which also serve particular communicative purposes of medical case reports. Medical case reports possess a range of unique characteristics which differ from those of research articles and other scientific genres within the framework of written medical discourse. It is to be emphasized that it is highly important for medical professionals to master the major stylistic principles and communicative intentions of medical case report as a genre in order to share their findings with fellow researchers from all over the world. Hence, in the process of training future medical researchers, the analysis of the basic mechanisms of writing a medical case report should be an integral part of the curricula in English for Specific Purposes at universities.

There are some metabolic similarities between women with gestational diabetes mellitus (GDM) and polycystic ovary syndrome (PCOS); it is still uncertain, however, to what extent coexistence GDM and PCOS affects pregnancy outcome. The present study was designed to determine the obstetric and neonatal outcome in PCOS with GDM. A case-control study was conducted involving 261 GDM women. Thirty hundred-one cases had PCOS based on Rotterdam criteria and the other thirty hundred cases (control group) were women without PCOS. The subjects in each group were evaluated regarding obstetric and those women whose documentation's were complete entered the study. In present study, women with PCOS and GDM had more than twofold increased odds of preeclampsia (p = 0.003, CI = 1.56-5.01, and OR = 2.8) and PIH (p= 0.04, CI = 1.28-4.5, and OR= 2.4). Maternal PCOS and GDM were also associated with threefold increased odds of neonatal hypoglycemia (p= 0.004, CI= 1.49-6.58, and OR= 3.13). Our finding emphasized that pregnant PCOS patients should be followed carefully for the occurrence of various pregnancy and neonatal complications including hypertension and hypoglycemia. We suggested that these neonates should be given more care regarding hypoglycemia symptoms.

5-Aminolevulinic acid (5-ALA)-induced fluorescence-guided resection is a widely used procedure for patients with malignant gliomas. However, the clinical application of 5-ALA for surgery in primary central nervous system lymphoma (PCNSL) is uncommon. Here, we present a case of PCNSL treated using 5-ALA-induced fluorescence-guided resective surgery. A 70-year-old woman presented with cerebellar ataxia, and magnetic resonance imaging revealed an irregularly shaped and homogenously enhanced mass with surrounding brain edema in the vermis that extended to the right hemisphere of the cerebellum. Under the preoperative diagnosis of a malignant glioma in the cerebellum, the patient underwent 5-ALA-induced fluorescence-guided surgery. Under blue light illumination, the tumor revealed strong 5-ALA-induced fluorescence. The tumor was identified as a diffuse large B-cell lymphoma. After partial resection, the patient received adjuvant chemotherapy and radiotherapy. Importantly, the neurological deficit of the patient improved, and recurrence of the tumor was not observed 21 months post-surgery. Together with previous reports, this case study emphasizes the efficacy of the surgical application of 5-ALA for PCNSL.

Neuro psychiatry 1943: the role of documentary film in the dissemination of medical knowledge and promotion of the U.K. psychiatric profession.

PubMed

Jones, Edgar

2014-04-01

In 1943, Basil Wright produced a documentary film about the treatment of servicemen and civilians with psychological disorders at Mill Hill Emergency Medical Service Hospital. Funded by the Ministry of Information, Neuro Psychiatry was shot to convince influential clinicians and policy makers in North America that the British had developed expertise in the management of psychiatric casualties. By emphasizing novel and apparently effective interventions and excluding severe or intractable cases from the film, Wright encouraged an optimistic sense of achievement. Filmed at a time when victory was considered an eventual outcome, the picture presented a health service to which all had access without charge. Children and unemployed women, two groups excluded under the 1911 National Insurance Act, had been required to pay for healthcare in the prewar period and were shown receiving free treatment from the Emergency Medical Service. However, the therapeutic optimism presented in the film proved premature. Most U.K. battle casualties arose in the latter half of the conflict and follow-up studies failed to confirm the positive outcome statistics reported in the film. Aubrey Lewis, clinical director of the hospital, criticized research projects conducted at Mill Hill for a lack of rigor. The cinematographic skills of Wright and director Michael Hankinson, together with their reformist agenda, created a clinical presentation that emphasized achievements without acknowledging the limitations not only of the therapies offered by doctors but also the resources available to a nation at war.

Moebius' syndrome (MS) is characterized by a nonprogressive facial palsy associated with impairment in eye abduction, which can be uni- or bilateral. Some authors raise the possibility that patients with MS may suffer from social stigmatism due to their facial dysmorphism and that constant teasing and bullying perpetrated by people in the same social circle are adjuvants in the development of low self-esteem, behavioral problems, and even psychiatric disorders. Psychological stress, anxiety, and depression are factors contributing to both development and impairment of autoimmune diseases, such as systemic lupus erythematosus (SLE). The objective of this work is to report the case of a patient with MS who developed SLE. In the present case report, we have emphasized the importance of both clinical dental examination and surgeon-dentist in the early diagnosis of systemic diseases by considering that these conditions can affect both syndromic and normoreactive patients. © 2018 Special Care Dentistry Association and Wiley Periodicals, Inc.

"Spice" (Synthetic Marijuana) Induced Acute Myocardial Infarction: A Case Series.

2017-01-01

Marijuana is the most widely abused "recreational" substance in the United States, with highest prevalence in young adults. It is reported to cause ischemic strokes, hepatitis, anxiety, and psychosis. Although it is associated with dose dependent tachycardia and can lead to coronary vasospasm, it has not been directly related to acute myocardial infarction (AMI). Marijuana induced coronary vasospasm can result in endothelial denudation at the site of a vulnerable atherosclerotic plaque in response to hemodynamic stressors, potentially causing an AMI. Spice refers to herbal mixture with composition and effects similar to that of marijuana and therefore is referred to as "synthetic marijuana." Herein, we report 3 cases of spice induced ST-segment elevation myocardial infarction. All patients were relatively young and had few or absolutely no risk factors for cardiovascular disease. All patients underwent emergent coronary angiography, with two needing stent placement and the third requiring only aspiration thrombectomy. Our case series emphasizes the importance of suspecting and investigating synthetic marijuana use in low risk young adults presenting with AMI.

The origin point of the anterior choroidal artery (AChA) is variable, typically arising from the supraclinoid internal carotid artery (ICA) distal to the posterior communicating artery (PComA) on either the posterolateral or posterior aspect of the ICA. Variations of AChA origin have important clinical implications, and rare origins reported previously include the ICA bifurcation and middle cerebral artery. We provide illustrations of a case of a shared-origin PComA and AChA. A young girl presented with intracranial hemorrhage and underwent angiography to evaluate for an underlying cause. Ultimately, 3-dimensional rotational angiography incidentally demonstrated a common origin of the AChA with the PComA. A rare case of a shared-origin AChA and PComA is reported for angiographic illustration. The radiologic findings, embryology behind the development of the AChA, and neurosurgical and neurovascular relevance of this variant are discussed. The importance of recognizing the origin of the AChA is emphasized. Copyright © 2017 Elsevier Inc. All rights reserved.

Neonatal retroauricular cellulitis as an indicator of group B streptococcal bacteremia: a case report

PubMed Central

2009-01-01

Introduction The relation between cellulitis and Group B streptococcus infection in newborns and small infants was first reported during the early 1980s and named cellulitis-adenitis syndrome. We report a case of a neonate with cellulitis-adenitis syndrome in an unusual location (retroauricular). Case presentation A 21-day-old Caucasian female infant was brought to the emergency department with fever, irritability and a decreased appetite. Physical examination revealed erythema and painful, mild swelling in the right retroauricular region. The blood count and C-reactive protein level were normal. She was treated with ceftriaxone. The fever and irritability were resolved after 24 hours, and the cellulitis was clearly reduced after two days of hospitalization. Blood culture yielded Group B streptococcus. Conclusion A thorough evaluation must be done, and lumbar punctures for infants with cellulitis must be considered. We emphasize the lack of data about acute phase reactants to predict bacteremia and meningitis and to adjust the duration of parenteral antibiotic therapy to address this syndrome. PMID:20062760

2014-09-01

Tuberculosis (TB) is a chronic specific granulomatous disease and a major cause of death in developing countries. The clinical presentation of TB lesions of the oral cavity varies widely and can manifest as ulcerations, diffuse inflammatory lesions, granulomas and fissures. Oral lesions generally appear secondary to primary TB infection elsewhere, although primary infection of the oral mucosa by Mycobacterium tuberculosis has also been described. We hereby report a case of primary TB of the gingiva manifesting as gingival enlargement. Diagnosis was based on histopathological examination, complete blood count, X-ray chest and immunological investigations with detection of antibodies against M. tuberculosis. Anti-tuberculous therapy was carried out for over 6 months and was followed by surgical excision of the residual enlargement under local anesthesia. After 1-year follow-up, there was no recurrence of the disease. This case report emphasizes the need for dentists to include TB in the differential diagnosis of various types of gingival enlargements.

We report a case of a 46-year-old female who presented with a persistent lesion on the inferior right breast. The lesion was located within the scar from a breast augmentation procedure 12 years ago. The lesion had been treated as several conditions with no improvement. Biopsy revealed a superficial and nodular basal cell carcinoma, and the lesion was successfully removed with Mohs micrographic surgery. Basal cell carcinoma arising in a surgical scar is exceedingly rare with only 13 reported cases to date. This is the first reported case of basal cell carcinoma arising in a breast augmentation scar. We emphasize the importance of biopsy for suspicious lesions or those refractory to treatment, particularly those lesions that form within a scar.

Mass Distribution and Gravitational Potential of the Milky Way

NASA Astrophysics Data System (ADS)

Ninković, Slobodan

2017-04-01

Models of mass distribution in the Milky Way are discussed where those yielding the potential analytically are preferred. It is noted that there are three main contributors to the Milky Way potential: bulge, disc and dark halo. In the case of the disc the Miyamoto-Nagai formula, as simple enough, has shown as a very good solution, but it has not been able to satisfy all requirements. Therefore, improvements, such as adding new terms or combining several Miyamoto-Nagai terms, have been attempted. Unlike the disc, in studying the bulge and dark halo the flattening is usually neglected, which offers the possibility of obtaining an exact solution of the Poisson equation. It is emphasized that the Hernquist formula, used very often for the bulge potential, is a special case of another formula and the properties of that formula are analysed. In the case of the dark halo, the slopes of its cumulative mass for the inner and outer parts are explained through a new formalism presented here for the first time.

This article aims to present and discuss a case-study of human betterment through the arts applied to a children's hospital. The experience related to the betterment of these environments took place in the Children's Emergency Service of the University Hospital in Salamanca. After describing the context of the case-study some attention will be devoted to the phases of the process, emphasizing those aspects linked to children's care culture and their families as well as the symbolic dimension of the space and the participation of different professionals in the experience. The case-study is assessed from different standpoints but special importance is given to parents' opinions. 51 parents of children in the emergency unit were interweaved during a month. Parents valued positively the service and stated that artists' intervention had been beneficial for the children's emotional state. The article concludes with a debate about the meaning of the hospital environment and the quality associated with its physical premises.

The diagnosis of child abuse may be difficult and require a high index of suspicion on the part of the practitioners encountering the child and the family. System-related factors may also enable abuse or prevent the early recognition of abuse. Child abuse and neglect that goes undiagnosed may give rise to chronic abuse and increased morbidity-mortality. In this report, we present two siblings who missed early diagnosis and we emphasize the importance of systems issues to allow early recognition of child abuse and neglect.

The problem of teaching essential Artificial Intelligence (AI) methods is an important task for an educator in the branch of soft-computing. The key focus is often given to proper understanding of the principle of AI methods in two essential points - why we use soft-computing methods at all and how we apply these methods to generate reasonable results in sensible time. We present one interesting problem solved in the non-educational research concerning automated generation of specific algebras in the huge search space. We emphasize above mentioned points as an educational case study of an interesting problem in automated generation of specific algebras.

Cryopyrin-associated periodic syndrome.

Cryopyrin-associated periodic syndromes (CAPS) are characterized by apparently unprovoked attacks of fever, rashes, and musculoskeletal and sensorineural inflammation accompanied by high acute-phase reactants. Excessive interleukin-1 (IL-1) signaling appears to be a constant feature in the pathomechanism of the disease, driven by a gain-of-function mutation in the NLRP3 gene. Herein, we present the case of a 9-month-old boy with recurrent nonpruritic rashes and episodes of fever. The difficulties of early diagnosis due to initially mild clinical symptoms and the dramatic response to anti-IL-1 therapy after diagnosis emphasize the practical relevance of considering CAPS as a differential diagnosis in these patients. © 2012 Wiley Periodicals, Inc.

The importance of localizing pulmonary veins in atrial septal defect closure!

PubMed Central

2011-01-01

An 8-year-old girl was admitted for a simple closure of echocardiographically diagnosed Atrial Septal Defect (ASD). During the operation the right pulmonary veins orifices were not detected in the left atrium and attempt to localize them led to the discovery of three additional anomalies, namely Interrupted Inferior Vena Cava (IIVC), Scimitar syndrome, and systemic arterial supply of the lung. Postoperatively these finding were confirmed by CT angiography. This case report emphasizes the need for adequate preoperative diagnosis and presents a very rare constellation of four congenital anomalies that to the best of our knowledge is not reported before.

Cultivating Parabolas in the Parlor Garden: Reconciling Mathematics Education and Feminine Ideals in Nineteenth-Century America

NASA Astrophysics Data System (ADS)

Fiss, Andrew

2014-02-01

This article introduces the justification problem for mathematics, which it explores through the case study of 1820s-1840s rationales for the teaching of mathematics to women in the United States. It argues that, while educators in the 1820s justified women's studies through mental discipline (a common reason for men's study), those of the 1830s-1840s increasingly relied on separate, gendered justifications, tied to emerging ideals of middle-class femininity. This article therefore emphasizes the contingency of the justification problem, which serves to break the present-day cycle of gender stereotypes regarding mathematics.

Vortex methods for separated flows

NASA Technical Reports Server (NTRS)

Spalart, Philippe R.

1988-01-01

The numerical solution of the Euler or Navier-Stokes equations by Lagrangian vortex methods is discussed. The mathematical background is presented and includes the relationship with traditional point-vortex studies, convergence to smooth solutions of the Euler equations, and the essential differences between two and three-dimensional cases. The difficulties in extending the method to viscous or compressible flows are explained. Two-dimensional flows around bluff bodies are emphasized. Robustness of the method and the assessment of accuracy, vortex-core profiles, time-marching schemes, numerical dissipation, and efficient programming are treated. Operation counts for unbounded and periodic flows are given, and two algorithms designed to speed up the calculations are described.

St. Louis encephalitis is not an uncommon cause of seasonal meningoencephalitis in children. The clinical presentation is variable and may range from inapparent infection to a severe illness with diverse neurologic signs. A review of three recent cases of St. Louis encephalitis in children in Phoenix, Arizona, stresses the need to consider this type of encephalitis in patients with signs of brain stem dysfunction or acute cerebellar ataxia. The appearance of these clinical signs is supported by the pathologic changes that have been documented to occur, most frequently in the thalamus and brain stem. The importance of serologic identification to facilitate early vector control is emphasized. PMID:664627

a Point-Like Picture of the Hydrogen Atom

Faghihi, F.; Jangjoo, A.; Khani, M.

A point-like picture of the Schrödinger solution for hydrogen atom is worked to emphasize that "point-like particles" may describe as "probability wave function". In each case, the three-dimensional shape of the |Ψnlm(rn, cosθ)|2 is plotted and the paths of the point-like electron (it is better to say reduced mass of the pair particles) are described in each closed shell. Finally, the orbital shape of the molecules are given according to the present simple model. In our opinion, "interpretations of the Correspondence Principle", which is a basic principle in all elementary quantum text, seems to be reviewed again!

A young intact female dog was presented with urinary incontinence. Abdominal ultrasound revealed the presence of hyperechoic linear structures within the cranial vagina suggestive of foreign material. A computed tomography (CT) retrograde vaginourethrogram demonstrated the presence of a fistulous tract between the urethra and vagina. A presumptive diagnosis of urethrovaginal fistula due to migration of foreign material was made. The grass awn was removed with vaginoscopic-guided retrieval. Fourteen days later, surgical repair of the fistula and an ovariohysterectomy were done. This case report emphasizes the usefulness of CT for diagnosis and precise anatomical localization of genitourinary tract fistulas. © 2015 American College of Veterinary Radiology.

Titration in the treatment of the more troubled patient.

PubMed

Winer, J A; Ornstein, E D

2001-01-01

This article defines and discusses a modification of technique recommended by the authors in the psychoanalytic treatment of more troubled patients--a modification they call titration. Titration is defined as a conscious decision by the analyst to increase or decrease assistance (or gratification) gradually, in order to facilitate the analytic process. The authors emphasize the complexity of decisions in treatment by focusing on the decision-making processes that titration requires. Guidelines and a case vignette are presented. The authors conclude by considering some of the politics involved in the introduction of technique modifications, the salience of the titration concept, and directions for further exploration.

Painful Hashimoto's thyroiditis: myth or reality?

Rotondi, M; Capelli, V; Locantore, P; Pontecorvi, A; Chiovato, L

2017-08-01

Neck pain is a common complain, being in most cases due to non-thyroidal causes. However, a minority of patients suffer from painful thyroid diseases. Among them, sub-acute thyroiditis (SAT) is the most frequent one. Rare thyroid-related causes of neck pain include hemorrhage within a thyroid nodule as well as Riedel's thyroiditis and suppurative thyroiditis. In the last 30 years, a few cases of a painful variant of Hashimoto's thyroiditis (HT) have been described. Biochemical, ultrasound, and histologic features were clearly suggestive for HT in all of the published cases and definitely ruled out the diagnosis of SAT. While sound descriptions of painful HT are present in the literature, it is important to emphasize that only 20 cases were reported from the year 2000 until now. The condition, however, is clinically relevant because neck pain was reported to be refractory both to steroids and to other analgesic drugs, being thyroidectomy the only effective treatment for pain relief in these patients. This short review analyzes currently available data supporting a role for HT as a rare cause of neck pain.

2016-01-01

Gorlin-Goltz Syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS), is an autosomal dominant trait caused due to mutations in the patched tumor suppressor gene (PTCH) gene found on the long arm of chromosome 9. The syndrome is characterized by the presence of odontogenic keratocysts (OKCs), basal cell carcinomas, and skeletal malformations. Early diagnosis of the syndrome can be done by pedodontist as OKC is one of the early manifestations of the syndrome. Early diagnosis and treatment is important for long-term prognosis of the syndrome by reducing the severity of cutaneous carcinomas and deformities due to jaw cyst. The present case describes an 11-year-old patient with some typical features of NBCCS, which were diagnosed through its oral and maxillofacial manifestations. This case emphasizes the importance of pedodontist in early recognition of the syndrome. How to cite this article Tandon S, Chauhan Y, Sharma M, Jain M.

2012-11-30

In the Western world, cases of fatal child neglect due to starvation are extremely rare. When they do occur, particularly at the hands of a parent, such crimes are considered to be caused by mental disorders or personality disorders with severe affective impairment. The present report describes the peculiar case of a couple with a total of four children to care for, who starved a 16-month-old female to death, while all the other children were found to be healthy. After a forensic psychiatric assessment of their criminal responsibility, the couples were both judged guilty and sentenced to 30 years in prison. After a brief overview of the scientific knowledge about filicide, the authors propose a framework that may help to understand and explain the motivations underlying this dreadful crime that shocked the nation, and emphasize the role of the forensic psychiatric investigation into cases of filicide, which may contribute to gain a greater insight into the different motivational factors underlying this phenomenon.

1988-01-01

A stepwise heating analysis of Ar and Xe data from five neutron-irradiated whole rock LL chondrites (Soko Banja, Alta Ameen, Tuxtuac, Guidder, and Olivenza) is presented, emphasizing the complicated thermal history of ordinary chondrites. None of the present meteorites show a well-defined (Ar-40)-(Ar-39) apparent age plateau comprised of more than two release fractions. Most of the samples are found to yield well-defined high-temperature correlations between Xe-129/Xe-130 and Xe-128/Xe-130, and thus determinations of I-129/I-127 and Xe-129/Xe-130 at the time of isotopic closure for Xe. As in the case of other ordinary chondrites, the I-Xe systematics for LL chondrites correlate neither with a metamorphic grade nor with chronologies based opon other methods.

Patent foramen ovale and paradoxical embolization: a historical perspective.

PubMed

Lippmann, H; Rafferty, T

1993-01-01

The use of transesophageal echocardiography for intraoperative management of critically ill patients allows for routine evaluation of foramen ovale patency. The high prevalence of preoperatively unrecognized flow-patency of this structure has led investigators to emphasize the potential for paradoxical embolization in any patient undergoing anesthesia. This perspective led us to research earliest documentation of paradoxical embolization through a patent foramen ovale as a historical issue with present day relevance. This report examines the 1877 text of Julius Cohnheim in which he described a fatal case of paradoxical embolization to the middle meningeal artery. The 1880 manuscript of Moritz Litten documenting paradoxical embolization to the lower extremity is also presented. Both translations, to our knowledge, represent the first such representations of both the original 1877 edition of Cohnheim's work and Litten's journal article.

Global accuracies and error characteristics of presently orbiting satellite sensors are examined. The workshops are intended to lead to a better understanding of present capabilities for sea surface temperature measurement and to improve measurement concepts for the future. Data from the Advanced Very High Resolution Radiometer AVHRR and Scanning Multichannel Microwave Radiometer is emphasized. Some data from the High Resolution Infrared Sounder HIRS and AVHRR are also examined. Comparisons of satellite data with ship and eXpendable BathyThermograph XBT measurement show standard deviations in the range 0.5 to 1.3 C with biases of less than 0.4 C, depending on the sensor, ocean region, and spatial/temporal averaging. The Sea Surface Temperature SST anomaly maps show good agreement in some cases, but a number of sensor related problems are identified.

Juvenile Spring Eruption: A Variant of Perniosis?

Nabatian, Adam S; Rosman, Ilana S; Sturza, Jeffrey; Jacobson, Mark

2015-09-01

Juvenile spring eruption (JSE) is a unique condition that typically affects the helices of the ears of boys and young men. The classical clinical picture of JSE includes the abrupt onset of lesions after spending time outdoors in the early spring. Because of the papulovesicular nature of the rash and the history of sun exposure, JSE is considered a variant of polymorphous light eruption. In addition to the term "juvenile spring eruption," this entity has also been described under other less common terms such as "perniosis juvenilis vernalis aurium" or "spring perniosis," which emphasizes the onset in the spring and the possible pathogenic role of cold weather. We present a case of likely JSE with histopathologic features more consistent with perniosis than polymorphous light eruption and present a review the literature.

Ben Oumlil, A; Rao, C P

1992-01-01

Health care service markets in general and hospital care service markets in particular are characterized by many competitive developments. Hence, hospital marketing managers are forced to respond to these emerging competitive pressures. However, in formulating appropriate marketing management strategies, hospital managers need to have detailed knowledge about consumers and their behaviors in the marketplace. This paper focuses on the Nutrition Care division of the Department of Nutrition Service at a hospital and its venture into new service development. This case study is intended to emphasize the significance of acquiring adequate knowledge of customers in the health care services industry. It particularly emphasizes the critical role that this type of information concerning customer behavior plays in the development and implementation of an appropriate business expansion strategy. Furthermore, the aim of this case study is to help the reader to relate the acquired marketing information to the problem at hand, and make the appropriate marketing management decision.

Drivers of routine immunization coverage improvement in Africa: findings from district-level case studies

2015-01-01

There is limited understanding of why routine immunization (RI) coverage improves in some settings in Africa and not in others. Using a grounded theory approach, we conducted in-depth case studies to understand pathways to coverage improvement by comparing immunization programme experience in 12 districts in three countries (Ethiopia, Cameroon and Ghana). Drawing on positive deviance or assets model techniques we compared the experience of districts where diphtheria–tetanus–pertussis (DTP3)/pentavalent3 (Penta3) coverage improved with districts where DTP3/Penta3 coverage remained unchanged (or steady) over the same period, focusing on basic readiness to deliver immunization services and drivers of coverage improvement. The results informed a model for immunization coverage improvement that emphasizes the dynamics of immunization systems at district level. In all districts, whether improving or steady, we found that a set of basic RI system resources were in place from 2006 to 2010 and did not observe major differences in infrastructure. We found that the differences in coverage trends were due to factors other than basic RI system capacity or service readiness. We identified six common drivers of RI coverage performance improvement—four direct drivers and two enabling drivers—that were present in well-performing districts and weaker or absent in steady coverage districts, and map the pathways from driver to improved supply, demand and coverage. Findings emphasize the critical role of implementation strategies and the need for locally skilled managers that are capable of tailoring strategies to specific settings and community needs. The case studies are unique in their focus on the positive drivers of change and the identification of pathways to coverage improvement, an approach that should be considered in future studies and routine assessments of district-level immunization system performance.

Students' Learning Experiences from Didactic Teaching Sessions Including Patient Case Examples as Either Text or Video: A Qualitative Study.

2017-10-06

The aim of this study was to explore medical students' learning experiences from the didactic teaching formats using either text-based patient cases or video-based patient cases with similar content. The authors explored how the two different patient case formats influenced students' perceptions of psychiatric patients and students' reflections on meeting and communicating with psychiatric patients. The authors conducted group interviews with 30 medical students who volunteered to participate in interviews and applied inductive thematic content analysis to the transcribed interviews. Students taught with text-based patient cases emphasized excitement and drama towards the personal clinical narratives presented by the teachers during the course, but never referred to the patient cases. Authority and boundary setting were regarded as important in managing patients. Students taught with video-based patient cases, in contrast, often referred to the patient cases when highlighting new insights, including the importance of patient perspectives when communicating with patients. The format of patient cases included in teaching may have a substantial impact on students' patient-centeredness. Video-based patient cases are probably more effective than text-based patient cases in fostering patient-centered perspectives in medical students. Teachers sharing stories from their own clinical experiences stimulates both engagement and excitement, but may also provoke unintended stigma and influence an authoritative approach in medical students towards managing patients in clinical psychiatry.

Germ cell tumors are known to arise in the central nervous system, usually in the intracranial regions. However, primary spinal mixed germ cell tumors are extremely rare. This is the first reported case of intratumoral hemorrhage because of a primary spinal mixed germ cell tumor consisting of germinoma and immature teratoma in the conus medullaris of an adult patient that presented with rapid changes on magnetic resonance image (MRI). We report this rare case and discuss the clinical manifestations of an intramedullary spinal mixed germ cell tumor in adult. A case report. A 42-year-old woman experienced buttock numbness, and a spinal cord tumor was observed on the conus medullaris on MRI. The patient was scheduled for an operation in 1 month, but she developed sudden-onset neurologic deterioration. Rapid progression of the tumor was observed on follow-up MRI. The tumor was removed by emergency surgery and was identified as a primary mixed germinoma and immature teratoma. The patient received adjuvant chemotherapy and radiotherapy after gross total resection. The neurologic deficit of the patient was relieved, and recurrence of the tumor was not observed 26 months after the surgery. We present this rare case and emphasize the necessity of precise diagnosis and early treatment of primary spinal germ cell tumor. Close observation on MRI is required after surgery, and adjuvant chemotherapy and radiotherapy should be considered according to the pathologic features. Copyright © 2013 Elsevier Inc.

Emphasizing the only character: emphasis, attention and contrast.

PubMed

Chen, Lijing; Yang, Yufang

2015-03-01

In conversations, pragmatic information such as emphasis is important for identifying the speaker's/writer's intention. The present research examines the cognitive processes involved in emphasis processing. Participants read short discourses that introduced one or two character(s), with the character being emphasized or non-emphasized in subsequent texts. Eye movements showed that: (1) early processing of the emphasized word was facilitated, which may have been due to increased attention allocation, whereas (2) late integration of the emphasized character was inhibited when the discourse involved only this character. These results indicate that it is necessary to include other characters as contrastive characters to facilitate the integration of an emphasized character, and support the existence of a relationship between Emphasis and Contrast computation. Taken together, our findings indicate that both attention allocation and contrast computation are involved in emphasis processing, and support the incremental nature of sentence processing and the importance of contrast in discourse comprehension.

Overcoming confirmation bias in causal attribution: a case study of antibiotic resistance risks.

PubMed

Cox, Louis Anthony Tony; Popken, Douglas A

2008-10-01

When they do not use formal quantitative risk assessment methods, many scientists (like other people) make mistakes and exhibit biases in reasoning about causation, if-then relations, and evidence. Decision-related conclusions or causal explanations are reached prematurely based on narrative plausibility rather than adequate factual evidence. Then, confirming evidence is sought and emphasized, but disconfirming evidence is ignored or discounted. This tendency has serious implications for health-related public policy discussions and decisions. We provide examples occurring in antimicrobial health risk assessments, including a case study of a recently reported positive relation between virginiamycin (VM) use in poultry and risk of resistance to VM-like (streptogramin) antibiotics in humans. This finding has been used to argue that poultry consumption causes increased resistance risks, that serious health impacts may result, and therefore use of VM in poultry should be restricted. However, the original study compared healthy vegetarians to hospitalized poultry consumers. Our examination of the same data using conditional independence tests for potential causality reveals that poultry consumption acted as a surrogate for hospitalization in this study. After accounting for current hospitalization status, no evidence remains supporting a causal relationship between poultry consumption and increased streptogramin resistance. This example emphasizes both the importance and the practical possibility of analyzing and presenting quantitative risk information using data analysis techniques (such as Bayesian model averaging (BMA) and conditional independence tests) that are as free as possible from potential selection, confirmation, and modeling biases.

Vocal fold self-disruption after phonotrauma on a lead actor: a case presentation.

PubMed

Behlau, Mara; Oliveira, Gisele; Pontes, Paulo

2009-11-01

It is well known that phonotraumatic events may produce laryngeal inflammation, vocal fold hemorrhage and different types of mass lesions. This study describes a vocal fold self-disruption that occurred on stage to a lead actor in the role of Richard III. The study design is as case presentation. A 43-year-old actor presented with a sudden voice loss that first occurred on stage after a series of presentations. He also had a cold-like condition that had not been treated. His past medical history included an average of ten cigarettes per day for ten years and a 10-year history of gastritis and stomach ulcer. Perceptual, acoustic, and laryngeal analyses were performed following pharmacological and voice therapy. Perceptual and acoustic analyses showed mild deviations whereas laryngeal visual examination revealed a complete right vocal fold detachment from the anterior commissure to the vocal process, with generalized hyperemia. A mild diffuse Reinke's edema was observed on the left vocal fold. Mild discomfort was present only during the first day of the acute period. Modified vocal rest was recommended and a series of vocal exercises were administered. The patient performed again 4 days later, after following a series of behavioral modification techniques that included casting guidelines during the subsequent 15 days. Healing was exceptional and his voice returned to normal. This unique case with an exceptional recovery emphasizes the etiological aspects of scar formation after phonotrauma. Positive contributing factors may include a good vocal technique and adequate training as well as the protective upregulated genes present in Reinke's edema.

Critical Pitfalls in the use of BRAF Mutation as a Diagnostic Tool in Thyroid Nodules: a Case Report.

2016-09-01

Thyroid fine-needle aspiration (FNA) cytology is the primary tool for the diagnostic evaluation of thyroid nodules. BRAF mutation analysis is employed as an ancillary tool in indeterminate cases, as recommended by the American Thyroid Association management guidelines. Hereby, we report the case of a 73-year-old woman who presented an 8-mm-size, ill-defined, left thyroid nodule. FNA resulted "suspicious for papillary thyroid carcinoma". BRAF mutation status was analyzed, and somatic BRAF (V600E) mutation identified. The patient underwent a total thyroidectomy. At histological examination, the nodule was composed of Langerhans cells, admixed with many eosinophils. A final diagnosis of Langerhans cell histiocytosis of the thyroid was made. Our case emphasizes the critical diagnostic pitfalls due to the use of BRAF (V600E) mutation analysis in thyroid FNA. Notably, BRAF (V600E) mutation is common in melanoma, colorectal carcinoma, lung carcinoma, ovarian carcinoma, brain tumors, hairy cell leukemia, multiple myeloma, and histiocytoses. Therefore, in cases of indeterminate FNA with unclassifiable atypical cells BRAF (V600E) mutated, the possibility of a localization of hystiocytosis or a secondary thyroid malignancy should be taken into account.

Tinea faciei (TF) is a common clinical form of tinea in children that is frequently misdiagnosed and treated with corticosteroids. No large case series of TF focusing on children have been published. The aim of this study was to analyze the main epidemiologic, clinical, and microbiologic features of TF in children over a period of 30 years and compare these features with those of other tineas. We undertook a retrospective study of 818 cases of tinea in children at a referral hospital in southern Spain, diagnosed between 1977 and 2006, concentrating for this study on TF. Of the 73 cases of TF diagnosed, 50.7% were in girls. Most children (46.6%) were 4 to 9 years old. At the time of diagnosis, 29.2% of the cases had been treated with topical steroids. The most frequently isolated dermatophyte was Trichophyton mentagrophytes, which was isolated significantly more frequently in TF than in the other tineas. Cases of TF in children were not extremely unusual, emphasizing that TF must be considered in children with inflammatory facial eruptions. This consideration and the more-frequent use of mycologic tests can help achieve the correct diagnosis, when present. © 2011 Wiley Periodicals, Inc.

2013-03-01

Attitude, Skills, Knowledge (ASK) - In this order, these are fundamental characteristics of scientific innovators. Through first-hand practice in using science to unpack and solve complex real-world problems, students can become self-motivated scientific leaders. This presentation describes the pedagogy of a recently developed interdisciplinary undergraduate science education program at the University of Massachusetts Amherst focused on addressing global challenges with scientific solutions. Integrated Concentration in Science (iCons) is an overarching concentration program that supplements the curricula provided within each student's chosen major. iCons is a platform for students to perform student-led research in interdisciplinary collaborative teams. With a schedule of one course per year over four years, the cohort of students move through case studies, analysis of real-world problems, development of potential solutions, integrative communication, laboratory practice, and capstone research projects. In this presentation, a track emphasizing renewable energy science is used to illustrate the iCons pedagogical methods. This includes discussion of a third-year laboratory course in renewable energy that is educationally scaffolded: beginning with a boot camp in laboratory techniques and culminating with student-designed research projects. Among other objectives, this course emphasizes the practice of using reflection and redesign, as a means of generating better solutions and embedding learning for the long term.

To identify pathogenic genomic imbalances in patients presenting congenital heart disease (CHD) with extra cardiac anomalies and exclusion of 22q11.2 deletion syndrome (22q11.2 DS). 78 patients negative for the 22q11.2 deletion, previously screened by fluorescence in situ hybridization (FISH) and/or multiplex ligation probe amplification (MLPA) were tested by chromosomal microarray analysis (CMA). Clinically significant copy number variations (CNVs ≥300kb) were identified in 10% (8/78) of cases. In addition, potentially relevant CNVs were detected in two cases (993kb duplication in 15q21.1 and 706kb duplication in 2p22.3). Genes inside the CNV regions found in this study, such as IRX4, BMPR1A, SORBS2, ID2, ROCK2, E2F6, GATA4, SOX7, SEMAD6D, FBN1, and LTPB1 are known to participate in cardiac development and could be candidate genes for CHD. These data showed that patients presenting CHD with extra cardiac anomalies and exclusion of 22q11.2 DS should be investigated by CMA. The present study emphasizes the possible role of CNVs in CHD.

Vascular Ehlers-Danlos syndrome (vEDS) is a life-threatening connective tissue disorder due to its high tendency of arterial and organ rupture. Pulmonary complications in vEDS are rare. We present a young male patient with vEDS who developed severe pulmonary complications and severe rupture of the iliac artery at different stages of his life. Vascular Ehlers-Danlos syndrome was diagnosed based on clinical manifestations and confirmed by the identification of COL3A1 gene mutation. Due to high bleeding tendency and weak cardiopulmonary capacity, conservative treatment was taken for him. To our knowledge, this is the first report of vEDS case in which the patient developed both pulmonary complications and dissection of large arteries. Our report emphasizes the importance of considering vEDS when an adolescent develops unexplained pulmonary cysts with fragility of lung tissues. Genetic counseling and close monitoring should be performed for earlier diagnosis and prevention of severe complications of large arteries. The typical presentations of vEDS were also discussed by means of a review of case reports on vEDS with pulmonary complications.

Best practices for evaluating the capability of nondestructive evaluation (NDE) and structural health monitoring (SHM) techniques for damage characterization

Aldrin, John C.; Annis, Charles; Sabbagh, Harold A.; Lindgren, Eric A.

2016-02-01

A comprehensive approach to NDE and SHM characterization error (CE) evaluation is presented that follows the framework of the `ahat-versus-a' regression analysis for POD assessment. Characterization capability evaluation is typically more complex with respect to current POD evaluations and thus requires engineering and statistical expertise in the model-building process to ensure all key effects and interactions are addressed. Justifying the statistical model choice with underlying assumptions is key. Several sizing case studies are presented with detailed evaluations of the most appropriate statistical model for each data set. The use of a model-assisted approach is introduced to help assess the reliability of NDE and SHM characterization capability under a wide range of part, environmental and damage conditions. Best practices of using models are presented for both an eddy current NDE sizing and vibration-based SHM case studies. The results of these studies highlight the general protocol feasibility, emphasize the importance of evaluating key application characteristics prior to the study, and demonstrate an approach to quantify the role of varying SHM sensor durability and environmental conditions on characterization performance.

Re-evaluating the concept of "dominant/index tumor nodule" in multifocal prostate cancer.

2014-05-01

Prostate cancer (PCa) often presents as a multifocal disease with heterogeneity in Gleason score (GS) and genetic alterations. Dominant/index tumor nodule (DN), the largest nodule in a multifocal disease, is presumed to harbor the most aggressive biological behavior and therefore dictate the overall clinical behavior of PCa. In this study, we examined the pathological features of DN and re-evaluated the validity of the "DN" concept in multifocal PCa. A total of 201 consecutive radical prostatectomy specimens were totally submitted and examined. All independent cancer foci were recorded with prognostically important pathological parameters. Unifocal and multifocal disease was present in 25 (12.4 %) and 176 (87.6 %) cases, respectively. In 20 (11.3 %) multifocal cases, the highest GS, the largest tumor volume (TV), and extraprostatic extension (EPE) did not concur in the same tumor nodules. Non-DNs had a higher GS and EPE in 13 cases each and had both the highest GS and EPE in 5 cases. In the majority of multifocal prostate cancer (88.7 %), DNs have the highest GS and EPE. In these cases, DN is still a valid concept and can be used for assigning overall GS and procuring tissue for research. However, in a significant number of cases (11.3 %), the largest TV, the highest GS, and EPE did not concur in the same tumor nodules. In these cases, pathologists should de-emphasize the concept of DN. Instead, they should place the emphasis on the multifocal nature of the disease and document the pathological features of all independent tumor foci that have the largest TV, the highest GS, and EPE.

Two patients with sideroblastic anemia secondary to zinc-induced copper deficiency absorbed excess zinc secondary to oral ingestion. The source of excess zinc was a zinc supplement in one case; in the other, ingested coins. In each case, the sideroblastic anemia was corrected promptly after removal of the source of excess zinc. These two cases emphasize the importance of recognizing this clinical entity, since the myelodysplastic features are completely reversible.

Three-dimensional (3D) crime scene documentation using 3D scanners and medical imaging modalities like computed tomography (CT) and magnetic resonance imaging (MRI) are increasingly applied in forensic casework. Together with digital photography, these modalities enable comprehensive and non-invasive recording of forensically relevant information regarding injuries/pathologies inside the body and on its surface. Furthermore, it is possible to capture traces and items at crime scenes. Such digitally secured evidence has the potential to similarly increase case understanding by forensic experts and non-experts in court. Unlike photographs and 3D surface models, images from CT and MRI are not self-explanatory. Their interpretation and understanding requires radiological knowledge. Findings in tomography data must not only be revealed, but should also be jointly studied with all the 2D and 3D data available in order to clarify spatial interrelations and to optimally exploit the data at hand. This is technically challenging due to the heterogeneous data representations including volumetric data, polygonal 3D models, and images. This paper presents a novel computer-aided forensic toolbox providing tools to support the analysis, documentation, annotation, and illustration of forensic cases using heterogeneous digital data. Conjoint visualization of data from different modalities in their native form and efficient tools to visually extract and emphasize findings help experts to reveal unrecognized correlations and thereby enhance their case understanding. Moreover, the 3D case illustrations created for case analysis represent an efficient means to convey the insights gained from case analysis to forensic non-experts involved in court proceedings like jurists and laymen. The capability of the presented approach in the context of case analysis, its potential to speed up legal procedures and to ultimately enhance legal certainty is demonstrated by introducing a number of representative forensic cases.

Knowledge diffusion in social work: a new approach to bridging the gap.

PubMed

Herie, Marilyn; Martin, Garth W

2002-01-01

The continuing gap between research and practice has long been a problem in social work. A great deal of the empirical practice literature has emphasized practice evaluation (usually in the form of single-case methodologies) at the expense of research dissemination and utilization. An alternative focus for social work researchers can be found in the extensive theoretical and research literature on knowledge diffusion, technology transfer, and social marketing. Knowledge diffusion and social marketing theory is explored in terms of its relevance to social work education and practice, including a consideration of issues of culture and power. The authors present an integrated dissemination model for social work and use a case example to illustrate the practical application of the model. The OPTIONS (OutPatient Treatment In ONtario Services) project is an example of the effective dissemination of two research-based addiction treatment modalities to nearly 1,000 direct practice clinicians in Ontario, Canada.

Penis deformity after intra-urethral liquid paraffin administration in a young male: a case report.

2008-10-07

Self-induced injections of liquid substances mainly for penis enlargement is a well-documented but still rather uncommon practice in the western world. Herein we present the case of a 30-year-old male who self-inflicted, twice in a six-month-period, intra-urethral liquid paraffin and tied up his penis with a cord in order to achieve both enlargement and elongation. He arrived in our emergency department suffering from suprapubic pain; physical examination revealed a rather unique deformity of the penis. He finally refused any treatment and absconded. Side effects after paraffin administration are various and sometimes severe. Most of the times surgical treatment is needed and radical excision together with follow-up seems the best modality. Such practices emphasize on the public's misbelieves and that some aspects of sexual medicine are yet covered with the veil of misconception.

Surveying the SO(10) model landscape: The left-right symmetric case

Deppisch, Frank F.; Gonzalo, Tomás E.; Graf, Lukas

2017-09-01

Grand unified theories (GUTs) are a very well motivated extensions of the Standard Model (SM), but the landscape of models and possibilities is overwhelming, and different patterns can lead to rather distinct phenomenologies. In this work we present a way to automatize the model building process, by considering a top to bottom approach that constructs viable and sensible theories from a small and controllable set of inputs at the high scale. By providing a GUT scale symmetry group and the field content, possible symmetry breaking paths are generated and checked for consistency, ensuring anomaly cancellation, SM embedding and gauge coupling unification. We emphasize the usefulness of this approach for the particular case of a nonsupersymmetric SO(10) model with an intermediate left-right symmetry, and we analyze how low-energy observables such as proton decay and lepton flavor violation might affect the generated model landscape.

The case for moderate gun control.

DeGrazia, David

2014-03-01

In addressing the shape of appropriate gun policy, this essay assumes for the sake of discussion that there is a legal and moral right to private gun ownership. My thesis is that, against the background of this right, the most defensible policy approach in the United States would feature moderate gun control. The first section summarizes the American gun control status quo and characterizes what I call "moderate gun control." The next section states and rebuts six leading arguments against this general approach to gun policy. The section that follows presents a positive case for moderate gun control that emphasizes safety in the home and society as well as rights whose enforcement entails some limits or qualifications on the right to bear arms. A final section shows how the recommended gun regulations address legitimate purposes, rather than imposing arbitrary restrictions on gun rights, and offers concluding reflections.

Cyanotic congenital heart disease (CCHD) is a life-threatening cardiac defect that requires palliative or corrective surgery in early life. Major advances in medical and surgical management have resulted in the survival of CCHD patients to adulthood with or without corrective surgery, though some are at risk of development of end-stage renal disease (ESRD) due to cyanotic nephropathy (CN). There is little or no information on the initiation and maintenance of hemodialysis (HD) in such patients. We present here a case of a 44-year-old man with complete transposition of the great arteries and CN-related ESRD. He had only received a bi-directional Glenn's operation and still suffered persistent severe hypoxemia and impaired cardiac function. ESRD was successfully treated with HD over more than 4 years. The case emphasizes the need for special attention in the selection and initiation of renal replacement therapy.

Assessment of red blood cell parameters and peripheral smear at different temperatures in case of cold agglutination disease.

PubMed

Gupta, V

2014-03-01

Cold agglutination disease (CAD) is characterized by an auto-antibody which is able to agglutinate red blood cells (RBCs) at temperatures lower than that of the body, and subsequently to activate the complement system responsible for lysis of RBCs. Patients show hemolytic anemia of varying degrees of severity, which arise or worsen upon exposure to low temperatures. We describe a case who presented with fever and symptoms of asthenia. His investigations yielded bizarre RBC parameters which led to suspicion of a rare CAD, which was confirmed on reviewing RBC parameters, peripheral smear and direct Coomb's test at different temperatures. Hence, we suggest assessment of bizarre RBC parameters and peripheral smear can help in laboratory testing and diagnosis of CAD. It should also not pose embarrassment in laboratory testing to the pathologist for making an early and accurate diagnosis, thus emphasizing the need for an early treatment of CAD.

2015-01-01

Case summary An indoor 9-year-old castrated male domestic cat was referred with a 4 month history of increased upper airway noise. Computed tomography revealed a nasopharyngeal polypoid mass, which was removed endoscopically with basket forceps. Histopathology was compatible with a polypoid granulomatous pharyngitis with Cryptococcus-like organisms. This was supported by a positive serum latex cryptococcal antigen agglutination test (LCAT). Minimal inflammation of the nasal tissue was noted on histopathology, with no evidence of fungus. Following endoscopic removal of the mass, the patient was treated with systemic antifungal medication (itraconazole). One year after diagnosis, the LCAT titer was negative and the cat remained free of clinical signs. Relevance and novel information This case report emphasizes the importance of considering Cryptococcus species as a potential etiology in cats presented with signs of nasopharyngeal obstruction with an isolated nasopharyngeal polypoid mass, even if kept indoors.

Acute compartment syndrome is increased tissue pressure exceeding perfusion pressure in a closed compartment resulting in nerve and muscle ischemia. Common precipitating causes are crush injuries, burns, substance abuse, osseous or vascular limb trauma. This is a case of 42year old female with history of hypothyroidism who presented to emergency room with acute onset of severe pain and swelling in right lower extremity. Physical examination was concerning for acute compartment syndrome of right leg which was confirmed by demonstration of elevated compartmental pressures. No precipitating causes were readily identified. Further laboratory testing revealed uncontrolled hypothyroidism. Management included emergent fasciotomy and initiating thyroid hormone replacement. This case represents a rare association between acute compartment syndrome and uncontrolled hypothyroidism. We also discuss the pathogenesis of compartment syndrome in hypothyroid patients and emphasize the importance of evaluating for less common causes, particularly in setting of non-traumatic compartment syndrome.

Norrie Disease (ND) is a rare X-linked recessive disorder characterised by congenital blindness due to severe retinal dysgenesis. Hearing loss and intellectual disability is present in 30-50 % cases. ND is caused by mutations in the NDP gene, located at Xp11.3. The authors describe mutation analysis of a proband with ND and subsequently prenatal diagnosis. Sequence analysis of the NDP gene revealed a hemizygous missense mutation arginine to serine in codon 41 (p.Arg41Ser) in the affected child. Mother was carrier for the mutation. In a subsequent di-chorionic di-amniotic pregnancy, the authors performed prenatal diagnosis by mutation analysis on chorionic villi sample at 11 wk of gestation. The fetuses were unaffected. This is a first mutation report and prenatal diagnosis of a familial case of Norrie disease from India. The importance of genetic testing of Norrie disease for confirmation, carrier testing, prenatal diagnosis and genetic counseling is emphasized.

Metastatic Crohn disease is a rare cutaneous manifestation of Crohn disease characterized by granulomatous lesions discontinuous with the diseased areas of the gastrointestinal tract. We report a case of a 32-year-old woman with history of Crohn disease who was admitted for treatment of cellulitis after presenting with a tender erythematous plaque of the left calf. Microbiological tests including tissue cultures were negative. A skin biopsy revealed granulomatous dermatitis consistent with metastatic cutaneous Crohn disease. Owing to concomitant perianal fistulas and abscesses and prior infusion reaction to infliximab, the patient was treated with certolizumab, a pegylated tumor necrosis factor (TNF) inhibitor combined with methotrexate resulting in complete resolution of the skin lesion. This case emphasizes the importance of recognizing this rare skin manifestation of Crohn disease and adds certolizumab as one of TNF inhibitors useful in the treatment of metastatic cutaneous Crohn disease.

We report a case of Cotard's syndrome associated with psychotic symptoms. A 27-year-old man was admitted to hospital with the diagnosis of schizophreniform disorder. His presenting symptoms, which had started 1 month before hospital admission, were somatic delusions of gastrointestinal and cardiovascular malfunction and the absence of a stomach, which resulted in a decrease in weight from 75 kg to 63 kg in 1 month. Cranial computed tomographic images showed dilatation of the lateral and third ventricles, whereas magnetic resonance imaging revealed central atrophy and lateral ventricle dilatation. Single- photon emission computed tomography demonstrated left temporal, left frontal and left parietal hypoperfusion. The patient did not respond to antipsychotic therapies, but he was successfully treated with electroconvulsive therapy. This report emphasizes that Cotard's syndrome may be accompanied by lesions of the left hemisphere and that electroconvulsive therapy could be the first-line therapy in such patients with psychotic disorder.

Kratom use as a herbal supplement is on the rise in the United States, with reported medical outcomes and lethal effects suggesting a public health threat. Even though the Drug Enforcement Administration has included kratom on its drugs of concern list and the FDA has published a press release to identify it as an opioid with a potential for abuse, its therapeutic and side effects are still not well defined in the literature. Here, we present a case of a 32-year-old man with a history of kratom use who became acutely ill with a brief prodromal illness, followed by jaundice and elevated liver enzymes showing a cholestatic picture, and his successful treatment. In this case, we emphasize the need for awareness of kratom exposure as a key contributor in the expansion of the opioid crisis, with therapeutic benefits earned at the expense of potentially lethal side effects.

Cystic echinococcosis (CE) is a zoonotic disease; in places such as Turkey where livestock is common, it is an endemic health concern. The most commonly involved organ is the lungs in children. Pulmonary cysts can be asymptomatic; in some cases, they may rupture and become symptomatic. Ruptured lung hydatid cysts may often be confused with tuberculosis (Tbc) radiologically and clinically. . In this report, we present an 8-year-old female patient admitted with cough, fever, and sputum persisting since 2 weeks; her chest radiography and computed tomography (CT) findings initially indicated Tbc, but the follow-up surgery led to a diagnosis of ruptured lung CE. We want to emphasize that in children belonging to places where livestock is common, if respiratory symptoms are observed, CE and tuberculosis must be considered in the differential diagnosis, and the final diagnosis should be supported by other microbiological-serological tests.

Systemic lupus erythematosus (SLE) is an autoimmune multisystem disease characterized by the development of antinuclear antibodies. Nowadays considered outdated, lupus erythematosus (LE) cell preparation served as a screening test for SLE for decades. However, the importance of discovering LE cells on routine cytology cannot be overemphasized. We report the case of a 30-year-old female in whom bone marrow aspiration (BMA) was performed during an investigative workup for pyrexia of unknown origin. The observation of LE cells in direct bone marrow smears (without the use of an anticoagulant) raised the suspicion of SLE, which was later confirmed by antinuclear antibody testing. In the present case, LE cells were observed on BMA performed for the investigation of fever of unknown origin. The unexpected observation of LE cells in BMA smears emphasizes the fact that good morphological observation of marrow aspirates can provide crucial clues to a previously unsuspected diagnosis.

Neonatal thyrotoxicosis is a rare condition caused by the transplacental passage of thyroid stimulating immunoglobulins from mothers with Graves' disease. We report a case of neonatal thyrotoxicosis with concurrent supraventricular tachycardia (SVT). The female infant, who was born by section due to breech delivery and meconium in the amniotic fluid at 36 weeks of gestation, presented with tachycardia on day 7. Her heart rate was between 260 and 300 beats/min, and an electrocardiogram revealed ongoing SVT. Sotalol was effective after two cardioversions in maintaining sinus rhythm. Thyroid function studies revealed hyperthyroidism in the infant, and her mother was found to have Graves' disease. Since symptoms and signs can vary, especially in preterm infants with neonatal hyperthyroidism, we want to emphasize the importance of prenatal care and follow-ups of Graves' disease associated pregnancies and management of newborns after birth.

Because of their influence on psychological adaptation, biological rhythms associated with sleep have received growing attention during the last two decades. We are presenting an outline of (1) the ultradian rhythms of rapid-eye-movement (REM) sleep and of slow wave sleep (SWS), (2) the circadian rhythms of sleep/wake, body temperature and melatonine secretion, and (3) the infradian rhythms of the menstrual cycle and seasonal affective disorders emphasizing their importance in psychological adaptation. Particular attention is given to the consequences of the desynchronization of the circadian phase of sleeping and waking with that of core body temperature observed in the cases of abrupt time zone changes, shift work and some forms of insomnia and depression. New methods of intervention, such as the use of exposure to bright lights are discussed. A case is made for increased attention to a new form of hygiene, that of the biological rhythms associated with sleeping and waking. PMID:1958644

Oral cavity functions as an early indicator for a variety of systemic diseases. Early and accurate diagnosis of these underlying systemic disorders entails thorough examination of the oral mucosa, gingiva, teeth, tongue and other oral tissues. Although gingival changes may be related to local factors in the oral cavity, it can also be an expression of systemic conditions such as blood dyscrasias, endocrinal imbalance, and nutritional deficiencies. Leukemia, a malignancy of white blood cells is a dreadful disease, which, if not diagnosed properly and treated early may result in significant morbidity and mortality. Oral changes may be the first and only presenting signs in leukemic patients. This paper aims to throw light on an interesting case of acute leukemia diagnosed on the basis of oral signs and emphasizes the importance of thorough oral examination to identify the threatening condition.

Clear Cell Sarcoma of Kidney (CCSK) is known for its morphologic diversity, aggressive behaviour, tendency to recur and metastasis to bone. Amongst the various morphologic subtypes, anaplastic CCSK is associated with worse prognosis. Here, we report a case of this rare variant of CCSK. A five-year-old boy presented with history of lump and pain in abdomen since one week. The Computed Tomography (CT) scan revealed a large mass occupying the middle and inferior pole of right kidney. The clinical impression was Wilms tumour. Nephrectomy specimen was received and the diagnosis of CCSK anaplastic variant was offered only after excluding the differentials and after performing ancillary tests such as Immunohistochemistry (IHC). Thus, this case emphasizes the diagnostic challenges on morphology and the essential role of IHC in arriving at a definitive diagnosis, because failure to do so may deprive the child from optimal treatment.

Early diagnosis of botulism is essential for effective treatment. Electrophysiologic testing can be of major help to establish a prompt diagnosis, but the classic electrodiagnostic features of botulism are often elusive. Decrement or increment of compound muscle action potential (CMAP) amplitudes to slow or fast rates of nerve stimulation are often unimpressive or totally absent. Reduction of CMAP amplitudes, denervation activity, or myopathic-like motor unit potentials in affected muscles are found more frequently but they are less specific. In general, the electrophysiologic findings taken together suggest involvement of the motor nerve terminal, which should raise the possibility of botulism. The case reported here illustrates a common clinical presentation of botulism. This study emphasizes realistic expectations of the electrodiagnostic testing, the differential diagnosis, and the potential pitfalls often encountered in the interpretation of the electrophysiologic data.

The frequency of natural and manmade disasters along with increasing potential for public health emergencies emphasizes the need for emergency preparedness education. Because nurses are the largest group of health professionals to meet the needs of those affected by disasters and public health emergencies, schools of nursing need to prepare graduates who are knowledgeable about disaster and public health emergency management. The use of core competencies may be a means to ensure consistent application of best practices in disaster health care. The next step in competency development involves validation through evidence. Through documentation and dissemination of their experiences with emergency preparedness education, schools of nursing can provide supportive evidence to aid in competency development.

A 60-year-old woman with a history of recurrent headaches and blurred vision presented with bilateral optic disc edema. Optic neuritis was suspected, and intravenous methylprednisonlone was administered. Her vision declined to hand motions in both eyes, and subsequent evaluation revealed bilateral acute retinal necrosis with bilateral central retinal artery occlusions (CRAO). Aqueous humor polymerase chain reaction analysis was positive for herpes simplex virus (HSV), establishing a diagnosis of HSV-associated bilateral acute retinal necrosis (ARN) and meningitis. CRAO has rarely been reported in association with ARN, and a fulminant course with bilateral CRAO in association with ARN has not been previously reported. This case emphasizes the importance of careful peripheral examination in patients with presumptive optic neuritis, judicious use of systemic corticosteroid in this context, and the retinal vaso-obliterative findings that may be observed in the pathogenesis of ARN.

Hyperostosis frontalis interna (HFI) is a generalised pathological condition with an unknown etiology and variable clinical association. It is characterized by excess bone growth and manifested on the inner table of the frontal bone, occasionally extending onto the temporals, parietals and the occipital. The etiology of HFI is uncertain: it may be an unknown genetic predisposition, a common environmental exposure, or special metabolic diseases. The purpose of the present study is to report cases of HFI in some osteoarcheological series from Hungary and to emphasize the importance of the investigation of HFI in ancient populations. Twenty out of 803 adults with observable frontal bones exhibited HFI, ranging from early to mid-type, including 15 females and 5 males. Some overgrowths with edges were blending into the endocranial surface, and some were prominently protruding from the surface. Advanced cases of HFI (type C) were observed after age 40-60 years.

Ovarian hyperstimulation syndrome leading to ventriculoperitoneal shunt malfunction: Case report.

Ventriculoperitoneal shunt (VPS) insertion is a common neurosurgical procedure for hydrocephalus. Unfortunately, VPS malfunction is not uncommon, with an estimated cumulative rate of 32% at 5 years. As flow through the shunt is influenced by the pressure gradient between the ventricles and the peritoneal cavity, malfunction may be caused by elevated intra-abdominal pressure. We present a rare patient with ascites following ovarian hyperstimulation syndrome (OHSS) leading to shunt malfunction. OHSS is a potentially life-threatening complication of controlled ovarian stimulation caused by the administration of exogenous gonadotropins. In this patient clinical and radiological resolution of shunt dysfunction were achieved following peritoneocentesis. To our knowledge this is the first described case of OHSS leading to shunt malfunction, emphasizing the importance of awareness, early recognition and proper management of abdominal etiologies of VPS malfunction.

Human monkeypox (MPX) occurs at appreciable rates in the Democratic Republic of Congo (DRC). Infection with varicella zoster virus (VZV) has a similar presentation to that of MPX, and in areas where MPX is endemic these two illnesses are commonly mistaken. This study evaluated the diagnostic utility of two surveillance case definitions for MPX and specific clinical characteristics associated with laboratory-confirmed MPX cases. Data from a cohort of suspect MPX cases (identified by surveillance over the course of a 42 month period during 2009-2014) from DRC were used; real-time PCR diagnostic test results were used to establish MPX and VZV diagnoses. A total of 333 laboratory-confirmed MPX cases, 383 laboratory-confirmed VZV cases, and 36 cases that were determined to not be either MPX or VZV were included in the analyses. Significant (p<0.05) differences between laboratory-confirmed MPX and VZV cases were noted for several signs/symptoms including key rash characteristics. Both surveillance case definitions had high sensitivity and low specificities for individuals that had suspected MPX virus infections. Using 12 signs/symptoms with high sensitivity and/or specificity values, a receiver operator characteristic analysis showed that models for MPX cases that had the presence of 'fever before rash' plus at least 7 or 8 of the 12 signs/symptoms demonstrated a more balanced performance between sensitivity and specificity. Laboratory-confirmed MPX and VZV cases presented with many of the same signs and symptoms, and the analysis here emphasized the utility of including 12 specific signs/symptoms when investigating MPX cases. In order to document and detect endemic human MPX cases, a surveillance case definition with more specificity is needed for accurate case detection. In the absence of a more specific case definition, continued emphasis on confirmatory laboratory-based diagnostics is warranted.

2015-01-01

Background Pachyonychia congenita (PC) is a rare autosomal dominant disease whose main clinical features include hypertrophic onychodystrophy and palmoplantar keratoderma. The new classification is based on genetic variants with mutations in keratin KRT6A, KRT6B, KRT6C, KRT16, KRT17, and an unknown mutation. Here, we present a case of PC with unusual clinical and histological features and a favorable response to oral acitretin. Case A 49-year-old male presented with diffuse and striate palmoplantar keratoderma, thickened nails, knuckle pads, and pseudoainhum. Histology showed compact hyperkeratosis, prominent irregular acanthosis, and extensive epidermolytic hyperkeratosis, suggestive of Vörner's palmoplantar keratoderma. However, keratin 9 and 1 were not mutated, and full exome sequencing showed heterozygous missense mutation in type I keratin K16. Conclusion To our knowledge, epidermolytic hyperkeratosis has not been previously described with PC. Our patient had an excellent response, maintained over the last 5 years, to a low dose of acitretin. We wish to emphasize the crucial role of whole exome sequencing in establishing the correct diagnosis. PMID:26464567

In Balint groups, (para)medical professionals explore difficult interactions with patients by means of case presentations and discussions. As the process of Balint group work is not well understood, this article investigates Balint group meetings by making use of Lacan's theory of the four discourses. Five Balint group case presentations and their subsequent group discussion were studied, resulting in the observation of five crucial aspects of Balint group work. First, Balint group participants brought puzzlement to the group, which is indicative of the structural impossibility Lacan situates at the basis of all discourse (1). As for the group discussion, we emphasize 'hysterization' as a crucial process in Balint group work (2), the supporting role of the discourse of the analyst (3) and the centrality of discourse interactions (4). Finally, the potential transformation of the initial puzzlement is discussed (5). We conclude by putting forth the uniqueness of Balint group work as well as the potential usefulness of our analysis as a framework for Balint group leaders and professionals in charge of continuing medical education. © The Author(s) 2016.

Health care organizations must develop integrated health information systems to respond to the numerous government mandates driving the movement toward reimbursement models emphasizing value-based and accountable care. Success in this transition requires integrated data analytics, supported by the combination of health informatics, interoperability, business process design, and advanced decision support tools. This case study presents the development of a master's level cross- and multidisciplinary informatics program offered through a business school. The program provides students from diverse backgrounds with the knowledge, leadership, and practical application skills of health informatics, information systems, and data analytics that bridge the interests of clinical and nonclinical professionals. This case presents the actions taken and challenges encountered in navigating intra-university politics, specifying curriculum, recruiting the requisite interdisciplinary faculty, innovating the educational format, managing students with diverse educational and professional backgrounds, and balancing multiple accreditation agencies. © The Author 2016.

Gitelman syndrome is an autosomal recessive tubulopathy characterized by hypokalemia, hypomagnesemia, metabolic alkalosis and hypocalciuria. The majority of patients do not present with symptoms until late childhood or adulthood, and the symptoms are generally mild. We report here the first case of Gitelman syndrome presenting with the biological features of Fanconi syndrome and an early polyuria since the neonatal period. We discuss in this article the atypical electrolytes losses found in our patient, as well as the possible mechanisms of severe polyuria. A 6-year-old Caucasian girl was admitted via the Emergency department for vomiting, and initial laboratory investigations found hyponatremia, hypokalemia, metabolic acidosis with normal anion gap, hypophosphatemia, and hypouricemia. Urinalysis revealed Na, K, Ph and uric acid losses. Thus, the initial biological profile was in favor of a proximal tubular defect. However, etiological investigations were inconclusive and the patient was discharged with potassium chloride and phosphorus supplementation. Three weeks later, further laboratory analysis indicated persistent hypokalemia, a metabolic alkalosis, hypomagnesemia, and hypocalciuria. We therefore sequenced the SLC12A3 gene and found a compound heterozygosity for 2 known missense mutations. Gitelman syndrome can have varying and sometimes atypical presentations, and should be suspected in case of hypokalemic tubular disorders that do not belong to any obvious syndromic entity. In this case, the proximal tubular dysfunction could be secondary to the severe hypokalemia. This report emphasizes the need for clinicians to repeat laboratory tests in undiagnosed tubular disorders, especially not during decompensation episodes.

Tentorial dural arteriovenous fistula presenting as myelopathy: Case series and review of literature

2014-01-01

Dural arteriovenous fistula (DAVF) is a rare type of cerebral arteriovenous malformation. Common presenting symptoms are related to hemorrhage. However, rarely these patients may present with myelopathy. We present two cases of DAVF presenting as rapidly progressive myelopathy. Two treatment options are available: microsurgical interruption of the fistula and endovascular embolization. These treatment options of DAVFs have improved significantly in the last decade. The optimal treatment of DAVFs remains controversial, and there is an ongoing debate as to whether primary endovascular or primary microsurgical treatment is the optimal management for these lesions. However, despite treatment a high percentage of patients are still left with severe disability. The potential for functional ambulation in patients with DAVF is related to the time of intervention. This emphasizes the important of early diagnosis and early intervention in DAVF. The eventual outcome may depend on several factors, such as the duration of symptoms, the degree of disability before treatment, and the success of the initial procedure to close the fistula. The usage of magnetic resonance imaging and selective angiography has significantly improved the ability to characterize DAVFs, however, these lesions remain inefficiently diagnosed. If intervention is delayed even prolonged time in rehabilitation does not change the grave prognosis. This review outlines the presentation, classication and management of DAVF as well as discussing patient outcomes. PMID:25516869

There are few reported cases of cutaneous intestinal metaplasia or primary adenocarcinoma arising at the ileostomy site following panproctocolectomy. These complications have been seen almost exclusively in patients with familial adenomatous polyposis and inflammatory bowel disease (IBD). However, benign intraepidermal colonic mucosa at a reversed ileostomy site in a patient without familial adenomatous polyposis or IBD has not been documented. We report a case of a 51-year-old female with a history of colonic adenocarcinoma who presented with pruritic, erythematous, scaly plaques on the right lower abdomen, present since reversal of her ileostomy in 2007. Skin biopsy revealed benign foci of colonic epithelium with no evidence of adenomatous change. Benign intraepidermal colonic mucosa was diagnosed based on histopathologic findings and immunohistochemistry. To our knowledge, this is the first case of intraepidermal benign colonic metaplasia forming in a patient following ostomy reversal. The case emphasizes the importance of patient education and physical examination of the stoma or stoma remnants for detection of unusual or changing lesions due to the risk for malignant transformation. It also demonstrates that benign colonic mucosa should be considered in the differential diagnosis when evaluating lesions near ileostomy sites, regardless of whether the patient has a history of familial adenomatous polyposis or IBD. © 2015 John Wiley & Sons A/S.

2017-09-01

In the Lesser Antilles, coastal inundations from hurricane-induced storm surges pose a great threat to lives, properties and ecosystems. Assessing current and future storm surge hazards with sufficient spatial resolution is of primary interest to help coastal planners and decision makers develop mitigation and adaptation measures. Here, we use wave-current numerical models and statistical methods to investigate worst case scenarios and 100-year surge levels for the case study of Martinique under present climate or considering a potential sea level rise. Results confirm that the wave setup plays a major role in the Lesser Antilles, where the narrow island shelf impedes the piling-up of large amounts of wind-driven water on the shoreline during extreme events. The radiation stress gradients thus contribute significantly to the total surge - up to 100 % in some cases. The nonlinear interactions of sea level rise (SLR) with bathymetry and topography are generally found to be relatively small in Martinique but can reach several tens of centimeters in low-lying areas where the inundation extent is strongly enhanced compared to present conditions. These findings further emphasize the importance of waves for developing operational storm surge warning systems in the Lesser Antilles and encourage caution when using static methods to assess the impact of sea level rise on storm surge hazard.

A new mutation of the PCNT gene in a Colombian patient with microcephalic osteodysplastic primordial dwarfism type II: a case report

PubMed Central

2014-01-01

Introduction Microcephalic osteodysplastic primordial dwarfism is a syndrome characterized by the presence of intrauterine growth restriction, post-natal growth deficiency and microcephaly. Microcephalic osteodysplastic primordial dwarfism type II is the most distinctive syndrome in this group of entities. Individuals affected by this disease present at an adult height of less than 100cm, a post-pubertal head circumference of 40cm or less, mild mental retardation, an outgoing personality and bone dysplasia. Case presentation We report the first case of a five-year-old Colombian boy of mixed race ancestry (mestizo), with clinical features of microcephaly, prominent and narrow nose, arched palate, amelogenesis imperfecta, short stature, tall and narrow pelvis, disproportionate shortening of fore-arms and legs, and mild coxa vara. Analysis of the PCNT gene by sequencing showed the presence of a nucleotide change in exon 10, c. 1468C>T, evidencing a new mutation not reported in the literature for microcephalic osteodysplastic primordial dwarfism. Conclusion The new mutation identified in this case could be associated with the severity of the phenotypic expression of the disease, resulting in the extreme short stature of the patient. Further studies are required to reach an explanation that can justify such findings, and it is vital to emphasize the importance of detection and follow-up by the epidemiological surveillance groups in birth defects and rare diseases.

2013-01-01

Wilms tumor (WT) with diffuse anaplasia has an unfavorable prognosis and is often (>70%) associated with mutations in the TP53 gene. Although most WTs are unilateral, 5-10% are bilateral, and they are almost always present with nephrogenic rests. The latter are considered a precursor of WT. Two cases of bilateral WTs with nephroblastomatosis, in which anaplastic changes were detected over a period of time, were analyzed using clinical, radiological, histopathological, and molecular-genetic data. TP53 was analyzed by direct sequencing of its full coding sequence and intron-exon boundaries in 11 fragments. DNA was extracted from paraffin-embedded or frozen specimens. High-resolution genomic copy number profiling was carried out by UCL Genomics on the Affymetrix Human Mapping 250K Nsp or Genome-Wide Human SNP Array 6.0 platform. Both cases demonstrated a strong association between the appearance of anaplastic clones and TP53 mutations. Synchronous ganglioneuroma was diagnosed in one case. Our cases are unique as they represent a long disease history and demonstrate the difficulties in managing rare cases of bilateral WT with anaplasia. These cases also emphasize the practical importance of modern molecular-genetic techniques and their clinical application. Moreover, they highlight the issue of the adequate sampling needed in order to gather comprehensive, efficient, and sufficient information about genetic events in a single tumor.

Malaria is an infectious disease caused by Plasmodium parasite. Sporadic cases have not been observed in Turkey since 2010, but imported malaria cases are still prevalent owing to migration. The present study aimed to evaluate Plasmodium falciparum malaria in patients hospitalized in our hospital. A total of 15 adult patients (14 males and 1 female) who were diagnosed with malaria and who were managed at our clinic between January 2011 and 2017 were evaluated retrospectively for their epidemiological, clinical, and laboratory findings; treatment; and prognosis. Of the 15 cases, 14 (93.3%) were male and (6.7%), female. All patients had a history of travelling to endemic areas, and none of them undertook regular chemoprophylaxis. Fever (100%), splenomegaly (86.7%), hepatomegaly (26.7%), leukopenia (13.3%), thrombocytopenia (80%), elevated liver function tests (40%), and increased serum creatinine levels (13.3%) were found in the patients. The number of import cases is increasing owing to tourism, migration, and deficiency in eradication programs. Malaria caused by P. falciparum is an import case in Turkey. The current study emphasizes on the necessity of providing proper education to Turkish individuals traveling to endemic areas for the purpose of work or travel and on the necessity of initiating chemoprophylaxis.

Congenital high airway obstruction syndrome (CHAOS) is a near fatal condition, except when the ex utero intrapartum treatment (EXIT) procedure is performed as rescue. After antenatal diagnosis of the condition, counseling regarding prognosis and outcome needs to be provided. We describe here a case with CHAOS due to isolated fetal laryngeal atresia, presented at our center at 33-week gestation. After counseling regarding the uncertain outcome, consent for elective caesarean was not given. Intact cord resuscitation (ICR) was done as a rescue by a well-coordinated team during delivery. Tracheostomy was performed successfully under local anesthesia within five minutes, while the cord was still attached to the placenta. The baby had supraglottic stenosis on CT scan. Reconstructive surgery is planned after 8 months. The literature review showed 24 reports of 28 cases with intrinsic airway obstruction managed by EXIT, laryngeal atresia was the most common cause (18/28). The outcome was poor in tracheal agenesis (1/4 survived) whereas those having laryngeal web or small communication (4/4 survived) had better outcome. Tracheal reconstruction was done in 3/28 cases only. The case emphasizes that ICR and tracheostomy during vaginal delivery can rescue the baby. The literature reviewed provided insight into the outcome of CHAOS cases in world literature.

Scabies is a mandatory notifiable disease according to Croatian law. Due to an increased reports of scabies within a couple of years in Zagreb, we decided to present epidemiological characteristics of patients diagnosed with scabies in Zagreb. A retrospective survey was carried out in county Public Health Institute "Dr. Andrija Stampar" in Zagreb and analysis was performed for the period of 2010-2013 upon individual notifications on scabies cases. The patients are presented by sociodemographic data, diagnosis and treatment. In a 4 year period there were 246 scabies cases recorded in Zagreb. Cases have been registered in all quarters of the City. The highest incidence (50/100 000) was recorded in every child age group following by incidence of over 30/100 000 in elderly institutionalized in nursing homes. In almost two thirds of patients management of scabies has not been conducted in accordance to current guidelines. 10% of scabies cases were found in medical health personnel predominantly in those working in nursing homes and psychiatric wards. A small amount of cases 19 (8%) were infected outside Croatia; the majority of these cases 15 (78%) are registered within last two years. High percentage of scabies cases registered in nursing homes and psychiatric wards suggests that there is a need of raising awareness on scabies epidemiology and management by public health officers. Due to a higher incidence of scabies in children age, the obligation of medical practitioners is also to emphasize the importance of following treatment guidelines. In order to control scabies cases as well to prevent outbreaks within hospital wards or nursing homes there is an obligation of implementation of strict guidelines regarding treatment of scabies and a public health service referral.

Photoautotrophic microorganisms and bioremediation of industrial effluents: current status and future prospects.

2017-05-01

Growth of the industrial sector, a result of population explosion has become the root cause of environmental deterioration and has raised the concerns for efficient wastewater management and reuse. Photoautotrophic cultivation of microorganisms is a boon and considered as a potential biological treatment for remediation of wastewater as it sequesters CO 2 during growth. Photoautotrophs viz. cyanobacteria, micro-algae and macro-algae can photosynthetically assimilate the excessive pollutants present in the wastewater. The present review emphasizes on the achievability of microorganisms to bestow wastewater as the nutrient source for biomass production, which can further be reused for feed, food and fertilizers. To support this, various case studies have been cited that prove phycoremediation as a cost-effective and sustainable process over conventional wastewater treatment processes that requires high chemical load and more energy inputs.

Optimal use of human and machine resources for Space Station assembly operations

Parrish, Joseph C.

1988-01-01

This paper investigates the issues involved in determining the best mix of human and machine resources for assembly of the Space Station. It presents the current Station assembly sequence, along with descriptions of the available assembly resources. A number of methodologies for optimizing the human/machine tradeoff problem have been developed, but the Space Station assembly offers some unique issues that have not yet been addressed. These include a strong constraint on available EVA time for early flights and a phased deployment of assembly resources over time. A methodology for incorporating the previously developed decision methods to the special case of the Space Station is presented. This methodology emphasizes an application of multiple qualitative and quantitative techniques, including simulation and decision analysis, for producing an objective, robust solution to the tradeoff problem.

Effectiveness of an oral presentation depends on the ability of the speaker to communicate with the audience. An important part of this communication is focusing on two to five key points and emphasizing those points during the presentation. Every aspect of the presentation should be purposeful and directed at facilitating learners' achievement of the objectives. This necessitates that the speaker has carefully developed the objectives and built the presentation around attainment of the objectives. A presentation should be designed to include as much audience participation as possible, no matter the size of the audience. Techniques to encourage audience participation include questioning, brainstorming, small-group activities, role-playing, case-based examples, directed listening, and use of an audience response system. It is first necessary to motivate and gain attention of the learner for learning to take place. This can be accomplished through appropriate use of humor, anecdotes, and quotations.

Aspland, Helen; Llewelyn, Susan; Hardy, Gillian E; Barkham, Michael; Stiles, William

2008-11-01

An initial ideal, rational model of alliance rupture and rupture resolution provided by cognitive-behavioral therapy (CBT) experts was assessed and compared with empirical observations of ruptures and their resolution in two cases of successful CBT. The initial rational model emphasized nondefensive acknowledgment and exploration of the rupture. Results indicated differences between what therapists think they should do to resolve ruptures and what they actually do and suggested that the rational model should be expanded to emphasize client validation and empowerment. Therapists' ability to attend to ruptures emerged as an important clinical skill.

2010-11-01

The authors present the case of a ten-year-old Chinese boy who was taken to a hospital due to the presence of suspicious bruises on his body. The child was examined in the National Institute of Legal Medicine by forensic doctors and a forensic psychologist. Clinical characteristics of the case are summarized stressing that a better understanding of some kinds of integrative medicine (IM) may help to differentiate injuries resulting from those practices. This is the only and unique case diagnosed by the medico-legal services in Portugal. In fact a great range of IM practice has the potential to create confusion in the diagnosis of physical child abuse. This study focuses on the differential diagnosis of one specific kind of frequent skin injury usually seen in situations of both child abuse and IM (in this case TuiNa) - bruises. As the number of people who practice Traditional Chinese Medicine and other forms of IM increases in the Western world, the child protection community would benefit from familiarizing itselves with these practices to prevent social and/or legal conflicts that may arise from mistaken diagnoses of abuse. The objective of this case report is to emphasize the relevance of comprehensive and interdisciplinary evaluation of child abuse cases taking into account the specifics of each case, to achieve a proper diagnosis.

Rosenberg, Audrey; Almeida, Angelica; Macdonald, Heather

2012-01-01

This article examines cross-cultural therapeutic assessment in a community mental health clinic. The first case describes the work between a Caucasian assessor and a Mexican American family. The authors explore the metaphorical and literal translation of the findings from English to Spanish and the parallel process of translation of the self, experienced by both assessor and client. The second case describes the work between a Caucasian assessor and an African American adolescent. We describe the inherent challenge between the Eurocentric "task" orientation of the evaluation and the Afrocentric "relationship" orientation. We suggest that bridging the gap between cultures and overcoming cultural mistrust lay in the building of the assessor-client relationship. Fischer's concepts of rapport and intimacy are emphasized and expanded on as we emphasize the importance of cocreated meaning in cross-cultural assessment work.

Patients with TSHomas may present with hyperthyroidism, but the incidence of thyroid storm due to TSHomas has yet to be determined. We report a rare case of thyroid storm caused by TSHoma in a 54-year-old woman. Preoperatively she had symptoms of excessive sweating and palpitation. Blood tests showed inappropriate secretion of TSH with blood TSH 6.86 μ U/mL, fT3 19.8 pg/mL, and fT4 5.95 ng/dL. Magnetic resonance imaging (MRI) revealed a pituitary tumor with maximum diameter of 13 mm that was extirpated through transsphenoidal route. After operation the patient was stuporous and thyroid storm occurred presenting with hyperthermia, hypertension, and tachycardia. It was well managed with nicardipine, midazolam, steroids, and potassium iodide. Immunohistochemical staining of tumor specimen was positive for TSH and growth hormone (GH). One year after operation, fT3 and fT4 levels were still high. As her tumor was diagnosed to be GH- and TSH-producing adenoma, octreotide injection therapy was started, which normalized thyroid hormone levels. This is the second reported case with thyroid storm due to TSHoma and emphasizes the importance of strategies with interdisciplinary cooperation for prevention of such emergency conditions.

Varicella-zoster virus and herpes simplex virus types 1 and 2 are neurotropic viruses that can be reactivated after a surgical or stressful intervention. Although such cases are uncommon, consequences can be debilitating, and variable treatment responses merit consideration. We describe a 41-year-old male with a history of varicella-mediated skin eruptions, who presented with continuing right arm pain, burning, and numbness in a C6 dermatomal distribution following a C5-6 anterior cervical discectomy and fusion and epidural steroid injections. The operative course was uncomplicated and he was discharged home on postoperative day 1. Approximately ten days after surgery, the patient presented to the emergency department complaining of severe pain in his right upper extremity and a vesicular rash from his elbow to his second digit. He was started on Acyclovir and discharged home. On outpatient follow-up, his rash had resolved though his pain continued. The patient was started on a neuromodulating agent for chronic pain. This case adds to the limited literature regarding this rare complication, brings attention to the symptoms for proper diagnosis and treatment, and emphasizes the importance of prompt antiviral therapy. We suggest adding a neuromodulating agent to prevent long-term sequelae and resolve acute symptoms. PMID:24251050

Dandy-Walker complex and syringomyelia in an adult: case report and discussion.

Syringomyelia in association with the Dandy-Walker complex is rare and only 17 cases have been reported, mostly as autopsy findings or incidental reports in series for other conditions. We present a further case report and discuss the possible pathogenetic mechanisms of syrinx formation in the presence of the Dandy-Walker complex. We emphasize the role of foramen magnum obstruction and alteration in cerebrospinal fluid flow dynamics in syrinx formation. The therapeutic importance of disimpaction of the foramen magnum is stressed. A 39-year-old man presented with headache. As a child, he had had cystoperitoneal and ventriculoperitoneal shunts inserted for hydrocephalus in association with the Dandy-Walker complex. On examination, the patient had limited upgaze but was otherwise normal. Magnetic resonance imaging revealed a large cervicothoracic syrinx and a Dandy-Walker cyst obstructing the foramen magnum. The cystoperitoneal shunt was revised. The patient's headaches resolved, and follow-up imaging demonstrated resolution of the syrinx and disimpaction of the foramen magnum. Disimpaction of the foramen magnum can resolve syringomyelia in patients with the Dandy-Walker complex. This can be achieved by a shunt procedure or by formal foramen magnum decompression. The rarity of the association between the Dandy-Walker complex and syringomyelia prevents firm conclusions from being made regarding the best management strategy for this condition.

The Global Neurological Burden of Tuberculosis.

Central nervous system (CNS) involvement of tuberculosis (TB) is the most severe manifestation of TB and accounts for approximately 5 to 10% of all extrapulmonary TB (EPTB) cases and approximately 1% of all TB cases. TB meningitis (TBM) is the most common form of CNS TB, though other forms occur, often in conjunction with TBM, including intracranial tuberculomas, tuberculous brain abscesses, and spinal tubercular arachnoiditis. CNS TB often presents with nonspecific clinical features that mimic symptoms of other neurological conditions, often making diagnosis difficult. Defining neuroimaging characteristics of TBM include thick basal meningeal enhancement, hydrocephalus, and parenchymal infarctions most commonly involving the basal ganglia and internal capsule. Traditional cerebrospinal fluid sample analysis frequently requires lengthy times-to-result and have low sensitivity. Given the pitfalls of conventional CNS TB diagnostic methods, various molecular-based methods, including immunoassays and polymerase chain reaction (PCR)-based assays have emerged as alternative diagnostic tools due to their rapidity, sensitivity, and specificity. Expert panels on TBM have recently emphasized the need for standard research procedures with updated case definitions and standardized study methods, which will hopefully pave the way for more robust multicenter international studies. In this article, we review the epidemiology, diagnosis, molecular factors associated with disease presentation and outcome, and treatment of CNS TB.

To describe the clinical presentation and management of erosion and intrusion of silicone rubber implants that are used in scleral buckling procedures for the treatment of retinal detachment. The authors identified four patients from their practices during the last 20 years (1978-1998) who had erosion or intrusion of silicone rubber scleral buckles that were used to manage retinal detachment. Approximately 4400 scleral buckling procedures were performed during this period. A retrospective review of the medical records of all patients was performed. Factors that influenced management decisions concerning the intruding buckle are emphasized. All four patients had myopia. The interval between placement of the scleral buckle and development of intrusion ranged from 1 to 20 years. The buckles were intrascleral in three cases and episcleral in one. Recurrent detachment and vitreous hemorrhage were indications for surgical intervention in three cases. After the surgical removal of buckling elements, visual acuity stabilized in all patients and the retina remained attached in all cases. Erosion and intrusion of scleral buckle are rare complications of scleral buckling procedures. The intruding buckle may be left intact unless there is significant threat to the integrity of ocular structures, recurrent detachment, or hemorrhage. Manipulation of the encircling band or buckle does not necessarily alter the visual acuity or the status of the retina.

Objective There are some metabolic similarities between women with gestational diabetes mellitus (GDM) and polycystic ovary syndrome (PCOS); it is still uncertain, however, to what extent coexistence GDM and PCOS affects pregnancy outcome. The present study was designed to determine the obstetric and neonatal outcome in PCOS with GDM. Materials and methods A case-control study was conducted involving 261 GDM women. Thirty hundred-one cases had PCOS based on Rotterdam criteria and the other thirty hundred cases (control group) were women without PCOS. The subjects in each group were evaluated regarding obstetric and those women whose documentation's were complete entered the study. Results In present study, women with PCOS and GDM had more than twofold increased odds of preeclampsia (p = 0.003, CI = 1.56–5.01, and OR = 2.8) and PIH (p= 0.04, CI = 1.28–4.5, and OR= 2.4). Maternal PCOS and GDM were also associated with threefold increased odds of neonatal hypoglycemia (p= 0.004, CI= 1.49–6.58, and OR= 3.13). Conclusion Our finding emphasized that pregnant PCOS patients should be followed carefully for the occurrence of various pregnancy and neonatal complications including hypertension and hypoglycemia. We suggested that these neonates should be given more care regarding hypoglycemia symptoms. PMID:24971127

Industrial workstation design: a systematic ergonomics approach.

PubMed

Das, B; Sengupta, A K

1996-06-01

For the design of an industrial workstation, ergonomics guidelines are presented in a systematic manner. The guidelines provide a conceptual basis for a good workstation design. In a real world design situation, the implementation of the recommendations or guidelines needs the matching of the population anthropometry with the various components of the workstation. Adequate posture, work height, normal and maximum working areas, lateral clearance and visual requirement are determined for the intended user population. The procedure for determining the workstation dimensions and layout has been explained. The importance of building a mock-up of the designed workstation and its evaluation with representative subjects is emphasized. A case problem (supermarket checkstand workstation) is discussed to illustrate the workstation design procedure.

Brazilian spotted fever is an acute febrile infectious disease caused by Rickettsia rickettsii, transmitted by tick bite. As this disease is rare and has high mortality rates in Brazil, the clinical aspects and epidemiological data may help the diagnosis. We report a case of Brazilian spotted fever in a 19-year-old patient who presented maculopapular exanthema in the palmar region and upper limbs, lymphadenopathy, fever, chills, headache, conjunctival hyperemia, nausea, vomiting, dyspnea, myalgia, developing neurological signs and abdominal pain. He was treated with doxycycline with clinical improvement. We emphasize the importance of the recognition of this disease by dermatologists as cutaneous manifestations are the key findings to establish early diagnosis and prevent complications.

There are numerous causes for intracranial calcification in children. We describe an unusual cause of intracranial calcification in a child, namely, nephrogenic diabetes insipidus (NDI). A 12-year-old boy presented with seizures and developmental delay. MRI of the brain revealed intracranial calcification. Evaluation showed findings suggestive of NDI. The lack of evidence of any other metabolic defect suggests that these calcifications were secondary to NDI. He also had anemia for which he was investigated and diagnosed as thalassemia minor. Detailed literature review failed to reveal any reported association between NDI and thalassemia minor. We report this case to emphasize the importance of early diagnosis and treatment of NDI to prevent organic brain damage.

Necrotizing fasciitis is a rapidly progressive destructive soft tissue infection with high mortality. Streptococcus pneumoniae as etiologic agent of necrotizing fasciitis is extremely unusual. The increased susceptibility to Streptococcus pneumoniae infection in patients with systemic lupus erythematosus is probably a multifactorial phenomenon. We report a case of a patient, a 36-year-old Caucasian female with 8-year history of systemic lupus erythematosus who presented a fatal Streptococcus pneumoniae necrotizing fasciitis. The role of computed tomography and the high performance of blood cultures for isolation of the causative microorganism are emphasized. Once diagnosis is suspected, empiric antibiotic treatment must be prescribed and prompt surgical exploration is mandatory. © The Author(s) 2015.

Spacetime symmetries and topology in bimetric relativity

2018-04-01

We explore spacetime symmetries and topologies of the two metric sectors in Hassan-Rosen bimetric theory. We show that, in vacuum, the two sectors can either share or have separate spacetime symmetries. If stress-energy tensors are present, a third case can arise, with different spacetime symmetries within the same sector. This raises the question of the best definition of spacetime symmetry in Hassan-Rosen bimetric theory. We emphasize the possibility of imposing ansatzes and looking for solutions having different Killing vector fields or different isometries in the two sectors, which has gained little attention so far. We also point out that the topology of spacetime imposes a constraint on possible metric combinations.

We report a case of Q fever in a man who presented with fever of 40 days duration associated with thrombocytosis. Serological and molecular analysis (polymerase chain reaction) confirmed infection with Coxiella burnetii. A field study was conducted by collecting blood samples from the patient's family and from the animals in the patient's house. The patient's wife and 2 of 13 dogs showed seroreactivity. Our data indicate that C. burnetii may be an underrecognized cause of fever in Brazil and emphasize the need for clinicians to consider Q fever in patients with a febrile illness, particularly those with a history of animal contact.

Tc-99m TRODAT is cocaine analog and binds to the dopamine transporter in vivo . Tc-99m TRODAT single-photon emission computed tomography/computed tomography. (SPECT/CT) is useful for demonstrating presynaptic dopaminergic dysfunction in patients with Parkinsonism. However, few reports have shown extrastriatal uptake of Tc-99m TRODAT. We present the case of a 67-year-old male who underwent Tc-99m TRODAT SPECT/CT for evaluation of Parkinsonism. In addition to tracer binding in the striatum, tracer uptake was noted in an osteoid tumor of the clivus. Integrated SPECT/CT enabled precise localization and characterization of the extrastriatal site of tracer binding and emphasizes the importance of such coincidental findings.

Just a Collection of Recollections: Clinical Ethics Consultation and the Interplay of Evaluating Voices.

Bartlett, Virginia L; Bliton, Mark J; Finder, Stuart G

2016-12-01

Despite increased attention to the question of how best to evaluate clinical ethics consultations and emphasis on external evaluation (Hastings Center Report, ASBH Quality Attestation Process), there has been little sustained focus on how we, as clinicians, make sense of and learn from our own experiences in the midst of any one consultation. Questions of how we evaluate the request for, unfolding of, and conclusion of any specific ethics consultation are often overlooked, along with the underlying question of whether it is possible to give an accurate account of clinical ethics consultants' experience as experienced by ethics consultants. Before the challenge of submitting one's accounts or case reports for review and evaluation from others (at one's local institution or in the broader field), there is an underlying challenge of understanding and evaluating our own accounts. To highlight this crucial and deeply challenging dimension of actual clinical ethics practice, we present an account of a complex consultation, explicitly constructed to engage the reader in the unfolding experience of the consultant by emphasizing the multiple perspectives unfolding within the consultant's experience. Written in script format, the three perspectives presented-prototypical clinically descriptive account; didactically reflective and self-evidentiary account often seen in journal presentations; highly self-critical reflective account emphasizing uncertainties inherent to clinical ethics practice-reflect different manners for responding to the ways actual clinical involvement in ethics consultation practice accentuates and refocuses the question of how to understand and evaluate our own work, as well as that of our colleagues.

Early excision and grafting, an alternative approach to the surgical management of large body surface area levamisole-adulterated cocaine induced skin necrosis.

PubMed

Miner, Jason; Gruber, Paul; Perry, Travis L

2015-05-01

Levamisole-adulterated cocaine as a cause of retiform purpura progressing to full-thickness skin necrosis was first documented in 2003 and currently comprises over 200 reported cases. Whereas, its presentation, pathophysiology, and diagnostic workup have been reasonably well-defined, only one publication has significantly detailed its surgical management. For this reason there exists a relative absence of data in comparison to its reported incidence to suggest a preferred treatment strategy. In the case mentioned, treatment emphasized delayed surgical intervention while awaiting lesion demarcation and the monitoring of autoantibodies. At our institution we offer an alternative approach and present the case of a 34 year old female who presented with 49% TBSA, levamisole-induced skin necrosis managed with early surgical excision and skin grafting. The patient presented three days following cocaine exposure with painful, purpura involving the ears, nose, buttocks, and bilateral lower extremities which quickly progressed to areas of full-thickness necrosis. Lab analysis demonstrated elevated p-ANCA and c-ANCA, as well as leukopenia, decreased C4 complement, and urinalysis positive for levamisole, corroborating the diagnosis. Contrasting the most thoroughly documented case in which the patient underwent first surgical excision on hospital day 36 and underwent 18 total excisions, our patient underwent first excision on hospital day 10 and received only one primary excision prior to definitive autografting. To our knowledge, this is the largest surface area surgically treated that did not result in surgical amputation or autoamputation of limbs or appendages, respectively. We contend that early excision and grafting provides optimal surgical management of this syndrome while avoiding the morbidity seen with delayed intervention. Published by Elsevier Ltd.

Chorioamnionitis caused by Serratia marcescens in a healthy pregnant woman with preterm premature rupture of membranes: A rare case report and review of the literature.

The incidence of chorioamnionitis varies widely. The highest incidence is reported in preterm deliveries. Among preterm deliveries, chorioamnionitis usually occurs after preterm premature rupture of membranes (PPROM). To date, only five cases of chorioamnionitis due to Serratia marcescens were reported. Here we present a case of a pregnant woman with chorioamnionitis due to Serratia marcescens who delivered a premature neonate at 28 weeks and four days of gestation. We also conducted a review of the literature in order to identify and characterize the clinical presentation and outcomes of this rare infection. A 36 year old female (gravida 9, para 6) was admitted with cervical effacement of 16mm and intact membranes at gestational age of 25 weeks and five days. One week following her admission PPROM was noticed. Treatment with the standard antibiotic regimen for PPROM was initiated. Thirteen days after the diagnosis of PPROM (28 weeks and four days) she developed chills, abdominal pain, sub febrile fever, tachycardia, leukocytosis and fetal tachycardia, and a clinical diagnosis of chorioamnionitis was made. An urgent CS was performed. In the first post-operative day the patient developed surgical sight infection. Cultures obtained from the purulent discharge of the wound, as well as cultures from the placenta and uterine cavity that were obtained during surgery grew Serratia marcescens. The patient was treated with Meropenem for six days, with a good clinical response. We present a rare case of nosocomialy acquired Serratia marcescens chorioamnionitis in a patient with PPROM. This case emphasizes the need for good infection control measures. Our favorable outcome together with the scares reports in the literature, add insight into this type of rare infection.

We present a particular case of TRAP (twin reversed arterial perfusion) syndrome, which has a very rarely association of the simultaneous existence of a rudimentary malformed heart and brain, and also other malformations like abdominal wall abnormality, absent bladder with present kidneys, and absence of the lungs, which appear only in a few cases on the receptor twin from this sequence, malformations incompatible with life. A Caucasian 26-year-old pregnant woman, at the first pregnancy, with a monochorionic-diamniotic pregnancy, 26 weeks of gestation was referred to our hospital, for polyhydramnios. The patient delivered a living female newborn, weighing 950 g, with an Apgar score of 2 at one minute - the donor fetus and a second female newborn with multiple malformations, no signs of life and who weighed 2300 g - the receptor fetus. The anatomopathological examination confirmed the TRAP sequence associated with severe facial dysmorphism, bilateral phocomelia and cardiac malformations (rudimentary hypoplastic, univentricular) and a vascular anastomosis between the two umbilical cords. Anemia and cardiac complications which can lead to cardiac failure, appear early during pregnancy and caused the death of the pumping twin. We emphasize that in our case of TRAP sequence, the ultrasound examination established the diagnosis of the syndrome with high accuracy. Therefore, we can conclude that the existence of a rudimentary heart and a vascular anastomosis between the two umbilical cords supports the apparition of TRAP sequence. The early diagnosis of this pathology, the observation of the pregnancy with the help of weekly ultrasounds and the intrauterine interventions can increase the survival chances of the donor fetus from the TRAP sequence.

Intra-peritoneal chronic loculation in peritoneal dialysis patients - a new medical management approach.

Peritoneal dialysis (PD) limitation as renal replacement therapy is mostly due to peritonitis and complications. Formation and persistence of intra-abdominal loculations is often under-diagnosed. Encapsulated peritoneal sclerosis (EPS) is a life-threatening complication, but malnutrition, recurrent peritonitis and early membrane failure are insidious enemies that need to be emphasized. It is important to highlight the persistence of intra-abdominal fluid collection after clinical resolution of peritonitis in PD patients and to indicate a new medical management approach for an early diagnosis. During five years, we selected PD peritonitis cases followed by a six months interval free of infections. Ninety-seven subjects were followed at six months and one year after the first peritonitis. Tomography had been performed to patients presenting a positive inflammatory state without a specific infectious cause. Subjects presenting documented localized fluid collection (31 cases) were divided into: drug-treated group and those undergoing laparoscopy by a new surgery technique (seven patients); a comparison regarding the clinical state and biohumoral parameters was assessed in both groups. The prevalence of intra-abdominal loculation following an apparent resolved peritonitis was high (31.9%). The cases undergoing laparoscopy presented a better evolution - improved clinical status (p=0.001), higher hemoglobin values (p=0.06), significant lower doses of erythropoietin requirement (p=0.03), improved dialysis adequacy (p=0.005) and inflammatory state. In cases with confirmed fluid encapsulated loculation, an active attitude (screening imaging protocol and laparoscopic exploration) appears to be mandatory, decreasing the risk of EPS, a serious complication which pathology and treatment are incompletely understood.

This case study of the Argentina Road Safety Project demonstrates how the application of World Bank road safety project guidelines focused on institution building can accelerate knowledge transfer, scale up investment and improve the focus on results. The case study highlights road safety as a development priority and outlines World Bank initiatives addressing the implementation of the World Report on Road Traffic Injury's recommendations and the subsequent launch of the Decade of Action for Road Safety, from 2011-2020. The case study emphasizes the vital role played by the lead agency in ensuring sustainable road safety improvements and promoting the shift to a 'Safe System' approach, which necessitated the strengthening of all elements of the road safety management system. It summarizes road safety performance and institutional initiatives in Argentina leading up to the preparation and implementation of the project. We describe the project's development objectives, financing arrangements, specific components and investment staging. Finally, we discuss its innovative features and lessons learned, and present a set of supplementary guidelines, both to assist multilateral development banks and their clients with future road safety initiatives, and to encourage better linkages between the health and transportation sectors supporting them.

The objectives of this work were (i) geographical analysis of the 2012-2014 outbreak of rabies in Greece using GIS and (ii) comparative analysis of animal cases with data of potential human exposure to rabies together with environmental data, in order to provide information for risk assessment, effective monitoring and control. Most animal cases (40/48) involved red foxes, while domestic animals were also diagnosed with rabies. Overall, 80% of the cases were diagnosed in central northern Greece; 75% of the cases were diagnosed in low altitudes (<343·5 m), within a distance of 1 km from human settlements. Median distance from livestock farms was 201·25 m. Most people potentially exposed to rabies (889/1060) presented with dog bite injuries. Maximum entropy analysis revealed that distance from farms contributed the highest percentage in defining environmental niche profiles for rabid foxes. Oral vaccination programmes were implemented in 24 administrative units of the country during 2013 and 2014, covering a total surface area of ~60 000 km2. Rabies re-occurrence in Greece emphasizes the need for ongoing surveillance in cross-border areas and in areas with intense human activity.

The term semantic dementia was devised by Snowden et al. in 1989 and nowadays, the semantic dementia syndrome is recognized as one of the clinical forms of frontotemporal lobar degeneration (FTLD) and is characterized by a language semantic disturbance associated to non-verbal semantic memory impairment. Objectives The aim of this study was to describe a Brazilian sample of 19 semantic dementia cases, emphasizing the clinical characteristics important for differential diagnosis of this syndrome. Methods Nineteen cases with semantic dementia were evaluated between 1999 and 2007. All patients were submitted to neurological evaluation, neuroimaging exams and cognitive, language and semantic memory evaluation. Results All patients presented fluent spontaneous speech, preservation of syntactic and phonological aspects of the language, word-finding difficulty, semantic paraphasias, word comprehension impairment, low performance in visual confrontation naming tasks, impairment on tests of non-verbal semantic memory and preservation of autobiographical memory and visuospatial skills. Regarding radiological investigations, temporal lobe atrophy and/or hypoperfusion were found in all patients. Conclusions The cognitive, linguistic and of neuroimaging data in our case series corroborate other studies showing that semantic dementia constitutes a syndrome with well defined clinical characteristics associated to temporal lobe atrophy.
