Serum CRP and peripheral WBC were measured in 739 subjects with normal glucose regulation, 512 with impaired glucose regulation, and 502 newly diagnosed diabetic patients. Levels of insulin resistance (IR) were assessed using the index of homeostasis model (H...

BACKGROUND: Hip fractures in the elderly are associated with high 1-year mortality rates, but whether patients with other lower extremity fractures are exposed to a similar mortality risk is not clear. QUESTIONS/PURPOSES: We evaluated the mortality of elderly patients after distal femur fractures; determined predictors for mortality; analyzed the effect of surgical delay; and compared survivorship...

Tourette's syndrome in adults.

Added: 06:00 EDT 7 Aug 2010

Tourette's syndrome (TS) is defined as motor and phonic tics starting before age 18 years, and therefore most studies have focused on childhood TS, whereas the disorder in adults has not been well characterized. We reviewed medical records of all new TS patients referred to our Movement Disorders Clinic over the past 5 years, 19 years or older on initial evaluation and compared them with 100 TS pa...

Background D-dimers are used in conjunction with clinical probability scores in the assessment of venous thromboembolism (VTE), and they are elevated in other conditions, including malignancy, infection and arrhythmias. High levels of D-dimers in VTE are associated with adverse outcomes, including increased mortality. Their significance in patients without VTE has not previously been established. ...

Professional values and nursing.

Added: 06:00 EST 10 Nov 2010

The values of nursing arise from a concern with human flourishing. If the desire to become a nurse is a reflection of an aspiration to care for others in need then we should anticipate that those who choose to nurse have a tendency towards the values we would normally associate with a caring profession (care, compassion, perhaps altruism, and so on). However, these values require a secure base if ...

Shortness of breath is a common complaint in those with chronic liver disease. The differential diagnosis for this complaint includes primary pulmonary disorders, systemic disorders that affect the liver and lungs, and extrahepatic manifestations of portal hypertension. Orthotopic liver transplant, when appropriate, is the most effective therapy for many patients with dyspnea and chronic liver dis...

Dural tears in spine surgery.

Added: 06:00 EDT 3 Sep 2010

Dural tears are among the most commonly seen complications in spine surgery. Most studies in the literature indicate that long-term outcomes are not negatively affected, provided that the tears are diagnosed early and managed appropriately. Direct suture repair remains the preferred method for the management of durotomy caused by or found during surgery. However, recent literature reports encourag...

The recently licensed quadrivalent seasonal influenza vaccine (QIV) may provide better protection than the traditional trivalent influenza vaccine (TIV) as it includes one more influenza B strain. We developed a Monte Carlo simulation model to determine the economic value of a QIV compared to the TIV for 10 influenza seasons (1999-2009). The addition of the influenza B strain to convert the TIV in...

OBJECTIVE: To explore the associated diseases with positive anti-double stranded (ds) DNA other than systemic lupus erythematosus (SLE), and to determine an association if any, between its level in non-SLE causes. METHODS: This is a retrospective review of all patients with positive anti-dsDNA assay (more than 200 IU/ml) tested for any underlying etiology from January to December 2007 at King Abdu...

Actin structure and function.

Added: 06:00 EST 15 Feb 2011

Actin is the most abundant protein in most eukaryotic cells. It is highly conserved and participates in more protein-protein interactions than any known protein. These properties, along with its ability to transition between monomeric (G-actin) and filamentous (F-actin) states under the control of nucleotide hydrolysis, ions, and a large number of actin-binding proteins, make actin a critical play...

Stress reactions and stress fractures are defined as structural damage to bone caused by repetitive stress or stereotypical loading. The balance between loading and unloading of bone is disrupted in stress reactions and stress fractures through the sport-specific demands and by the exogenous or endogenous risk factors present. In sports orthopedics the localization of stress reactions and stress f...

BACKGROUND:: Cerebrospinal fluid (CSF) protein values decline over the first few months of life as the infant's blood-CSF barrier matures. However, published studies differ in the reported rate, timing, and magnitude of this decline. OBJECTIVE:: To quantify the age-related changes in CSF protein concentration and to determine accurate, age-specific reference values for neonates and young infants. ...

INTRODUCTION: Large-cell neuroendocrine carcinoma is an aggressive variant of large-cell carcinoma of the lung, which has poor survival in most series, resembling that of small-cell lung carcinoma. We report our retrospective assessment of surgically-resected cases of both tumours. METHODS: 33 large-cell neuroendocrine carcinomas and 16 peripheral small-cell lung carcinomas were reassessed retrosp...

OBJECTIVE: To explore the diagnosis and treatment of ganglion cysts of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) of the knees.

RESULTS: All patients were followed up at the clinic in a mean period of 2 years, and their symptoms...

The flexor carpi radialis is a wrist flexor and radial deviator with half the relative strength of flexor carpi ulnaris. In the majority of patients, the flexor carpi radialis tendon is expendable and is routinely used for various reconstructive procedures about the hand and wrist. Isolated flexor carpi radialis lacerations at the wrist are rare. Flexor carpi radialis tendon ruptures, which have b...

Diuretics are agents commonly used in diseases characterized by excess extracellular fluid, including chronic kidney disease, the nephrotic syndrome, cirrhosis and heart failure. Multiple diuretic classes, including thiazide-type diuretics, loop diuretics and K(+)-sparing diuretics, are used to treat patients with these diseases, either individually or as combination therapies. An understanding of...

BACKGROUND: Acute respiratory failure (ARF) is a common event in the advanced stage of amyotrophic lateral sclerosis (ALS) and may be rarely a presenting symptom. Frequently, such patients require intubation and mechanical ventilation (MV) and, in a large proportion, receive tracheostomy, as a consequence of weaning failure. In our study, we investigated postdischarge survival and quality of life ...

OBJECTIVE:: The purposes of this study were to assess modified radical hysterectomy including systematic pelvic and para-aortic lymphadenectomy followed by adjuvant chemotherapy in patients with para-aortic lymph node (PAN) metastasis in endometrial carcinoma and to identify the multivariate independent prognostic factors for long-term survival during the past 10 years. METHODS:: Between December ...

BACKGROUND: One of the main aims of routine antenatal care is to identify the 'at risk' fetus in order to apply clinical interventions which could result in reduced perinatal morbidity and mortality. Doppler ultrasound study of umbilical artery waveforms helps to identify the compromised fetus in 'high-risk' pregnancies and, therefore, deserves assessment as a screening test in 'low-risk' pregnanc...

The aim of this study is to present the diagnosis and management of anastomotic leakage after colon resection. Early diagnosis and urgent therapeutic intervention are required in order to avert life-threatening conditions that may be caused by anastomotic leakage. Minor leaks can be managed conservatively with successful outcomes. Major leaks should be managed operatively. In conclusion, leakage o...

Parkinson's disease (PD) is a degenerative, chronic and irreversible condition. Palliative medicine may play an important role in the care of patients with PD to maintain the quality of life. Scopolamine is a non-competitive antagonist at muscarinic acetylcholine receptors, which was used many years ago in the treatment for PD. To the best of our knowledge, there are no previously reported cases o...

The leak rates of different gastrointestinal anastomoses vary considerably but despite this there are common and general concepts for diagnosis and management. Early diagnosis and timely consistent therapy must guide management to prevent harm to the patients. Diagnosis of anastomotic leaks is coupled to clinical signs of the patients and should be initiated promptly. Dependent on the localization...

Bereavement is a severe stressor that typically incites painful and debilitating symptoms of acute grief that commonly progresses to restoration of a satisfactory, if changed, life. Normally, grief does not need clinical intervention. However, sometimes acute grief can gain a foothold and become a chronic debilitating condition called complicated grief. Moreover, the stress caused by bereavement, ...

INTRODUCTION AND HYPOTHESIS: We report our experience with surgical excision for treatment of Skene's gland abscess/infection after conservative measures have failed. METHODS: A retrospective review of patients that underwent surgical excision of Skene's gland abscess/infection by a single surgeon from 06/1995 to 09/2008 was performed. Patients were separated into groups based on indication for pr...

Atrophy of both the supraspinatus and infraspinatus muscles is usually caused by chronic rotator cuff tear, but may also derive from suprascapular nerve entrapment at the spinoglenoid notch. Isolated infraspinatus muscle atrophy is uncommon, and typically associates with suprascapular nerve entrapment occurring distal to the spinoglenoid notch. However, isolated atrophy of the infraspinatus muscle...

Triple-negative breast cancer (TNBC) relapses more frequently than hormone receptor-positive subtypes and is often associated with poor outcomes. This retrospective study reviewed the pattern of distant metastasis with regard to survival in patients with TNBC. A total of 205 TNBC patients were analyzed. TNBC patients with lung metastases had the longest median post-metastatic OS (with 95% confid...

Existing tests to measure the ability to recognize other people's emotional expressions (emotion recognition ability [ERA]) mostly focus on a single modality (usually the face) and include only a small number of emotions, restricting their ecological validity. Further, their reliability is often unsatisfactory. The goal of the present study was to develop a new ERA test (Geneva Emotion Recognition...

Monoclonal B cell lymphocytosis.

Added: 06:00 EDT 16 Jul 2010

Monoclonal B lymphocytosis (MBL) is an asymptomatic clinical syndrome wherein small B cell clones are detectable in the peripheral blood. MBL is common in the adult population, with an estimated prevalence of greater than 3% among individuals over age 50. Most MBLs have an immunophenotype similar to chronic lymphocytic leukemia (CLL). Recently, MBL has been shown to be a precursor state for CLL, t...

It is a broad spectrum molecule indicated in various forms of epilepsy of the adult and the child, but it is also prescribed in the treatment of different other pathologies of nervous system. The divalproate sodium is indicated in the treatment of bipolar disorders. The valproic acid is marketed under various pharmaceutical fo...

Summary Background: Prophylaxis of venous thromboembolism (VTE) in hospitalized medical patients is largely underused. We sought to assess the value of a simple risk assessment model (RAM) for the identification of patients at risk of VTE. Methods: In a prospective cohort study, 1180 consecutive patients admitted to a department of Internal Medicine in a 2-year period were classified as having a h...

Impairment in the ability to recognize and make sense of emotions has been hypothesized to be present in a sub-sample of people suffering from personality disorder (PD). In particular it is possible that difficulties recognizing and expressing feelings, or alexithymia, is related to many of the symptoms and problems in making sense of social interactions which are hallmarks of PD. In this study we...

A fluoroscopy-guided lumbar spine injection procedure may be complicated by immediate paralysis. Twelve cases (five recent and seven published) that occurred between 2002 and 2008 were reviewed (history of lumbar surgery, route of injection, image-guidance, injection of contrast, type of steroid, level of paraplegia, MR imaging features). MRI showed cord ischemia from arterial origin. The high num...

BACKGROUND: Primary incisional hernia repair is rarely successful, with recurrence rates ranging from 18% to 62%. We describe the integration of "components separation" herniorrhaphy with panniculectomy. METHODS: Twenty-two patients were treated. Standard panniculectomies and component separation were performed. Intravesical pressure was measured preoperatively, intraoperatively, and postoperative...

Yawning as a clinical sign of ischaemic stroke. :: Added: 06:00 EST 12 Nov 2010

Ocular pain is most commonly associated with redness and inflammation; however, eye pain can also occur in the absence of grossly visible pathology. Pain in the quiet eye can be the first sign of a number of threatening conditions. Many of these conditions such as intermittent angle closure glaucoma, carotid artery dissection, idiopathic intracranial hypertension, and giant cell arteritis can lead...

Traumatic brain injury (TBI) results in a variable degree of cerebral atrophy that is not always related to cognitive measures across studies. However, the use of different methods for examining atrophy may be a reason why differences exist. The purpose of this manuscript was to examine the predictive utility of seven magnetic resonance imaging (MRI) -derived brain volume or indices of atrophy for...

There is a wide variety in the appearance of normal female external genitalia. Nevertheless a specific prototype is promoted by the media, leading to a false sense that all other appearances are abnormal. As adolescents become sexually aware at an earlier age, most of them are worried about the appearance of their genitalia, especially when labia minora protrude beyond labia majora.  This is a p...

CT FEATURES OF PLEURAL MASSES AND NODULES.

Added: 06:00 EST 19 Nov 2011

Pleural space masses and nodules are rarely described on computed tomography (CT) in veterinary medicine and have only been described in patients with neoplasia. Our purpose was to describe the CT findings and diagnoses in seven patients with pleural masses and nodules. Two patients had broad-based, plaque-like pleural masses, both of which were due to neoplasia (primary pleural carcinoma, metasta...

Hyponatremia and hypernatremia are complex clinical problems that occur frequently in full term newborns and in preterm infants admitted to the Neonatal Intensive Care Unit (NICU) although their real frequency and etiology are incompletely known. Pathogenetic mechanisms and clinical timing of hypo-hypernatremia are well known in adult people whereas in the newborn is less clear how and when hypo-h...

BACKGROUND: Because the rate of acquired pyloric stenosis (APS) from truncal vagotomy is 15%, many surgeons perform pyloroplasty or pyloromyotomy at the time of esophagectomy. Endoscopic pyloric balloon dilatation (EPBD) is another method to manage APS. This study evaluated a cohort treated with preoperative EPBD. METHODS: This is a retrospective review of all patients treated with preoperative EP...

BACKGROUND: Melasma is a common pigmentary disorder among Asian women. The available therapies such as bleaching agents, chemical peeling, laser, and intense pulsed light are not satisfactory or safe. In the search to find a new treatment therapy for melasma, oral administration of tranexamic acid (TA) was studied clinically in Chinese patients. METHODS: The study enrolled 74 patients. Tranexamic ...

Importance of the field: Selective serotonin reuptake inhibitors (SSRIs) and serotonin noradrenaline reuptake inhibitors (SNRIs) are becoming increasingly used in the treatment of neuropathic pain and fibromyalgia. However, they are not without adverse effects and their efficacy has not been clear because of conflicting evidence. Areas covered in this review: We have examined the current evidence ...

INTRODUCTION: Acute hypercapnic respiratory failure (AHRF) is a serious condition observed in some patients with sleep apnea-hypopnea syndrome (SAHS). The objective of the present study was to study the clinical characteristics of SAHS patients who develop AHRF and their prognosis. PATIENTS AND METHOD: A total of 70 consecutive SAHS patients who survived an AHRF episode and 70 SAHS patients paired...

Erythromycin (ER) is an antibiotic with prokinetic activity. This property has led to its clinical use to improve gastric emptying in patients with gastroparesis. Several papers have reported the effectiveness of ER in such patients; however few of these studies have been well-conducted methodologically with evaluation of clinical endpoints and their results are often contradictory. A benefit/risk...

Clonazepam is a 1-4 benzodiazepine mainly used to treat epilepsy and epileptiform convulsion state. Rapidly absorbed after oral administration, it is widely distributed in the organism and is extensively converted in metabolites, poorly or not active, eliminated mainly in urine (70%) and feces. Elimination half-life is long, around 40 h. In adult and child, several studies showed a concentration-e...

Infection and Anemia.

Added: Unknown

Anemia most frequently accompanies infection in varying degrees and in different forms. Anemia of inflammation is the most common and is due to over-expression of hepcidin. This is followed by hemolytic anemia, red cell aplasia and blood loss. The degree of anemia may not necessarily be proportional to the severity of the infection, nor is it specific for the type of infection. A clear understandi...

BACKGROUND: Subconjunctival hemorrhages commonly occur idiopathically or from causes including ocular surgery, trauma, anticoagulation medications, or a Valsalva maneuver. When a hemorrhage persists or recurs, a more extensive list of differential diagnoses must be considered. This report details a case in which persistent subconjunctival hemorrhages led to the discovery of ocular adnexal lymphoma...
