With malignant tumors, a hydrocephalus after intraventricular hemorrhage or following distinct population of abnormal cells is usually present. Their occurrence is not pink, fibrillar, finely granular matrix containing nuclei without associated with lupus erythematosus or other autoimmune apparent cytoplasm; the fragments also may be acellular. Pial membrane fragments may also be found in similar although their presence in synovial fluid is rare. Occasionally, intact pyramidal-shaped neurons with round to Malignant cells may be numerous or only a rare cell may be oval nuclei, reticulated nuclear chromatin, a single nucleolus identified. Metastatic Inflammatory cells also may be seen within degenerating neural carcinoma and melanoma may also result in malignant cells tissue. The crystals Squamous Epithelial Cell may be found anywhere in the body approximately two weeks after bleeding/ hemorrhage. The crystal may be either intraSquamous cells derived from skin may be found in fluids as or extracellular. The abundant cytoplasm is lightly basophilic Pathognomonic of gout, monosodium urate crystals are found and may show evidence of keratinization or contain a few blue in synovial fluid. Epithelial cells from deeper layers of and are described classically as needle-like. They are 2 to 20 the epidermis have larger nuclei with a high nuclear-tofim in length and 0. They are reliably distinguished by use of a polarizing microscope and a first-order red compensator. Crystals Found in synovial fluid of patients with arthritis, pseudogout, Crystals, Not Otherwise Specified as well as in association with other diseases. The intracellular crystals are rod-shaped, rhomboid, either positively or negatively birefringent and interfere with diamond, or square forms, usually 1 to 20 fim long. Microorganisms Cholesterol Crystals Intracellular and extracellular organisms such as bacteria and yeast may be found in body fluids, particularly during the acute these crystals are extracellular and are one of the larger stage of an infection. Occasionally they may from nonspecific phagocytic debris commonly found in be needle-like. They are transparent and appear as a negative neutrophils and macrophages and from precipitated stain. They are strongly birefringent when viewed with this can be easily done with a gram stain. The organisms usually should be performed in accordance with defined laboratory have characteristic features that allow identification. Bacteria, Extracellular Yeast/Fungi, Extracellular A wide variety of bacteria can be seen in body fluids, including Yeast and fungi may assume a variety of forms. They oil immersion magnification, and may be seen in an may be within or outside of cells and can have a clear capsule intracellular or extracellular location. The spores may form pseudohyphae that branch and may Bacilli are rod-shaped bacteria, while cocci are spherical. These pseudohyphae may be up Filamentous bacteria are bacilli that grow in a branching, to 50 fim in length. These microorganisms can be accentuated, filamentous pattern, reminiscent of a tree. In the cerebrospinal fluid, Cryptococcus is the most commonly A Gram stain can be useful in separating these microorganisms encountered fungus. This microorganism is a round to oval into Gram-positive (blue/purple) and Gram-negative (pink) yeast-like fungus ranging from 3. An acid-fast stain is also useful in identifying certain diameter, usually with a thick mucopolysaccharide capsule. This error are often lightly basophilic on Wright-Giemsa stain, and the can be avoided by remembering that bacteria tend to be capsule is accentuated by staining with mucicarmine relatively uniform in size and shape, while stain precipitate is often irregular in shape and individual grains vary considerably in size. Miscellaneous Findings Ehrlichia/Anaplasma Fat Droplets Only recently recognized as an arthropod-borne infectious Fat droplets are found free in the fluid as translucent or nearly agent in humans, members of the genus Anaplasma translucent spheres of varying size. They are quite refractile (previously Ehrlichia) are small, Gram-negative obligate and are anucleate. Fat droplets may be endogenous or intracellular organisms currently classified as rickettsiae. They are seen in body cavities in pancreatitis round, dark purple-stained dots or clusters of dots (morulae) and dyslipidemia. Mitotic Figure Parasites When a cell undergoes mitosis, the regular features of a nucleus are no longer present. Instead, the nucleus appears A wide variety of parasites may be found in body fluids. It may take various shapes, including organisms usually have characteristic features that allow a daisy-like form or a mass with irregular projections.

Attention switching is involved in the third step and its failure will lead to failure of inhibitory control. The current study investigates specifcally how failure of attention switching results in Freezing of Gait. Montreal Cognitive Assessment was performed to rule out dementia and Frontal Assessment Battery was administered to check for overall executive functioning. The results show that the group having freezing of gait performed signifcantly poorly on congruent F(2, 42) = 7. The performance was unafected among the patients without freezing of gait but they had signifcantly lower mean reaction time than the healthy control group. Conclusion: this study suggests a defcit in the attention-switching component among patients with freezing of gait leading to failed switching from concurrent task to another task further leading to a defcient inhibitory control system. The group without freezing of gait experienced overall slowing suggested by the cognitive assessments but their task accuracy was unafected. The better understanding of this phenomenon will lead to better management of freezing of gait. Randomized controlled trials with larger sample sizes are needed to confrm these promising results. However, a causal link between such pathology and cognitive decline remains unproven. To address this question, there is a need to develop animal models where cortical syn pathology can be induced under controlled conditions. Rats were evaluated in two behavioral tests that probe prefrontal cognitive functions. Neuropathology was studied immunohistochemically using antibodies against human syn, Ser129-phosphorylated syn, and NeuN. The secondary measures included use of life sustaining therapies, discharge disposition, length of stay, and hospital costs. The correlation between defcits within performances in specifc neuropsychological tests and striatal dopaminergic binding were evaluated by multiple regression analyses. All the analyses were adjusted for the efect of age, sex, disease duration and presence of impulsive-compulsive disorders. Alternatively, this might be secondary to a disconnection of bioaminergic striato-cortical projections. Multi-modal imaging and longitudinal studies are warranted in order to clarify this issue. For long-term quality of life, age of onset, disease duration, and initial disability seem to be important. Data on the stimulation methods and the results of the cognitive assessments were extracted from the included studies. Secondly, the stimulation was performed at very short time-period, such as before, during or after the behavioral acquisition phase, as well as just before or during the behavioral assessment phase. Synchronizing electrical pulses with the applied cues overall showed better efects on cognition (z=6. Twenty-seven patients were excluded during 10-year follow-up period because of death, diagnosis of Parkinson-plus syndrome, and serious adverse efects. Results: At baseline, there was no signifcant diference of baseline clinical motor and non-motor features between two groups. We did the basal testing before treatment and another investigation after 6 months. Results: After 6 months the pain was reduced in group treated with Botulinum toxin (from 72% to 20%) but sleep problems were without signifcant changes (45% vrs 43%). The uniform non-motor symptoms scale for dystonia patients is needed for better outcome evaluation of our dystonia patients. Results: 18 patients corresponded to inclusion criteria: 5 adults and 13 children (M: F=10:8). Several device-related adverse events complicated postoperative management: lead fracture or dysfunction (7 patients). Five patients died despite intensive care unit management and advanced surgical therapies (2. Device dysfunction or fracture led to rebound worsening with possible status dystonicus in several patients. Patients were separated into three groups (gait, dysarthria, appendicular symptom control) based on chief complaint with some belonging to more than one group. Formal assessment with objective/quantitative outcome measures is currently ongoing and preliminary data (n=16) will be presented. Since 2012, the non-rechargeable dual channel neurostimulator available in France seems to have a shorter battery-life longevity compared to the previous model. The aim of this study is to evaluate battery-life longevity of the older and the more recent neurostimulators and to explore factors associated to battery life variations. The survival analysis, using the Kaplan-Meier estimator, showed a diference between the curves of the two devices (Log-rank test; p< 0. A carefully multidisciplinary assessment and long-term follow-up are recommended to recognize and treat this potentially preventable risk for mortality. Depending on ethnic background of the patients, frequencies and clinical manifestations of each subtype are various among diferent ethnic groups. We retrospectively reviewed medical records and organized data to fgure out characteristics, including age of onset, presence of family history, the number of trinucleotide repeats, clinical features and radiologic fndings. Heterogeneous clinical features were observed with diferent frequencies depending on subtypes. Characterization of these features would help to narrow the scope of candidate genes and eventually lead to cost efective and accurate diagnosis. This in turn, is the cause of neuronal loss in the cerebellum and brain stem as well as degeneration of spinocerebellar tracts as per literature reported. Conclusions:It has been found a signifcant correlation between the genetic characteristics and degree of atrophy in cerebellum (noted as the area of motor control) along with certain subcortical brain areas. Only few studies has been reported in Africa that has the lowest prevalence in the world. After giving their consent, patients were examined and laboratory evaluations were performed. A familial history of the disease was found in 85,7% cases, 14,3% of cases being sporadic. Choreic movements were the most predominant symptoms, found in 100% of our patients, followed by cognitive impairment and psychiatric disorders with 71,4% and 50%, respectively. Both phenomena may distinguish between primary dystonic muscles and secondary compensatory movements of the hand whilst writing, and help in selecting muscles to inject with botulinum toxin. They were assessed clinically at rest and on exteroand interoceptive stimuli, writing with both dystonic and non-dystonic hands. Primary dystonic posturing and the presence of contralateral overfow and mirror movements, were analysed.

At the end of the podcast, listeners will be able to: 1) List the differential diagnosis of sore throat in children, 2) Obtain a focused history of the relevant signs and symptoms in a child that presents with a sore throat, 3) Perform a physical exam in a child that presents with a sore throat, 4) Recognize the indications for further investigations, and 5) Discuss treatment and follow-up recommendations for common causes of sore throat. Your preceptor asks you to see Hailey, a 6-year-old female presenting with a 1-day history of sore throat. What is your approach to this common presentation and how will you organize your historyfi In children who are verbal, they will complain of pain in the back of their throat, especially when swallowing. In infants or children who are non-verbal, their symptoms are often non-specific and may include irritability, difficulty feeding orally, and crying during feeds. Sore throat is often used interchangeably with pharyngitis, but technically this means inflammation of the pharynx and is a sign on physical examination. Another term you may hear is tonsillitis, which describes inflammation of the tonsils, and can be seen in many causes of sore throat. A child that looks toxic or is in respiratory distress may require resuscitation and emergent care. For the history of presenting illness, we first need to assess onset and duration. Can the family or child pinpoint a specific event or activity that could have caused the sore throatfi The more pain the infant is in, the fussier, more irritable and more difficult to console he or she may be; for more information for pain assessment in pediatrics refer to the Pediatric Pain Management podcast Next, review any associated symptoms, such as cough, fever, or dysphagia. Assess fluid intake and hydration status; prior to toilet training this will be the number of wet diapers and thereafter frequency of urination. As most causes of sore throat are infectious, assess if the child has had any sick contacts and whether or not the child attends day care. After the history of presenting illness, you will want to collect a focused past medical history, including antenatal history and delivery, past and current medical conditions, immunization status, medications, allergies and developmental history. She appears to be uncomfortable but is not in respiratory distress, and you decide that she is not in need of emergent medical intervention and continue with your history. This morning, her throat was hurting so badly that she refused breakfast and has only had half a glass of juice. Pregnancy and delivery were unremarkable and she was born full term and has had no significant medical history. She is on no medications, has no allergies and has reached all her appropriate developmental milestones. Physical Exam the presumptive cause of the sore throat is often diagnosed by history and physical exam. It is important to know what you are looking for when you examine a child so that your exam is focused. These signs include significant work of breathing, cyanosis, and decreased level of consciousness. You can refer to the vital signs podcast or the pediatric vital signs reference chart on pedscases. Next, perform a respiratory exam, looking for signs of increased work of breathing, including nasal flaring, tracheal tug, use of accessory muscles, intercostal and subcostal indrawing, and paradoxical abdominal movement. In children with viral illnesses, stridor is a common finding as their small airways become smaller with the inflammation. Drooling indicates upper airway obstruction, preventing the drainage of secretions. Observe the posture and comfort level of the child: Are they leaning forward to maintain a patent airway, are they uncomfortable when leaning back or laying flatfi April 16, 2016 Remember, do not lay a child flat if they show signs of upper airway obstruction. If you suspect the child has epiglottitis, the patient should be transferred to an operating or intensive care room prior to intubation. Her vitals reveal normal blood pressure of 90/52, slight tachycardia of 110bpm, normal respiratory rate of 30, oxygen saturation is 98% on room air, and she is febrile with a temperature of 39C. On respiratory exam, there are no signs of increased work of breathing or nasal congestion. Head and neck exam reveals moist mucus membranes with no drooling, swollen erythematous purulent tonsils bilaterally, and an absence of petechiae or other lesions on the palate. On palpation, you note multiple tender and mobile anterior cervical lymph nodes all less than 1cm in diameter. Diagnosis and Treatment Now that we have gone through history and physical exam, we can narrow down our differential diagnosis and order investigations accordingly. In this section, we will review the presentations of the common infectious causes and the emergent infectious causes of sore throat, along with appropriate investigations and treatment. Children with viral pharyngitis often present with several days of rhinorrhea, cough, congestion, hoarseness, fever and a mild to moderate sore throat. Some children may have viral gastroenteritis and also present with vomiting and diarrhea. Generally, children will still be able to eat and drink but may have decreased appetite and fatigue. While in coxsackie A virus, also known as hand, foot and mouth disease, you may see herpangina or small vesicular or ulcerative lesions on the posterior oropharynx. Honey is the only treatment shown to be effective in reducing symptom severity of pharyngitis and cough but this can only be used in children over the age of one because of the risk of botulism. Other forms of supportive treatment include acetaminophen, ibuprofen, saline nasal spray, adequate hydration, and rest. Parents should be advised against using over-the-counter cough and cold medications as they are ineffective, and could cause more harm than benefits. Group A streptococcal pharyngitis is the next most important cause of sore throat. Streptococcal pharyngitis presents with acute onset of fever, moderate to severe sore throat, lymphadenopathy, and malaise. Younger children may have abdominal pain, nausea and Developed by Charissa Ho and Dr. It is most commonly seen in children 3-14 years of age and rare children under three. On exam, the child may be tachycardic due to fever, dehydration, or pain, and should have documented fevers. The rest of the exam will be unremarkable aside from anterior cervical lymphadenopathy and enlarged tonsils that are erythematous with/or without exudate. Not every child who presents with a sore throat needs a throat swab as ten percent of people are carriers of group A strep. Therefore, symptoms must be concerning for strep pharyngitis to minimize false positives. In a child with symptoms suggestive of viral pharyngitis, there is no need to swab. In cases that are less clear, there are validated risk assessment tools that can be used to determine whether a child requires a throat swab or antibiotic treatment. Ultimately, absence of cough, abrupt onset fever and presence of tonsillar exudates with swelling should prompt a throat swab. If a throat swab returns positive with group A streptococcus in a child with clinical signs of strep pharyngitis, he or she requires a 10 day course of penicillin or amoxicillin. The main reason to treat strep pharyngitis is to reduce the risk of complications and waiting 1-2 days for a swab result does not impact occurrence rates. Children with strep pharyngitis may develop two types of complications: suppurative meaning pus-forming, or non-suppurative. Suppurative complications include tonsillopharyngeal cellulitis or abscess, otitis media, meningitis and brain abscesses. Non-suppurative complications include scarlet fever, acute rheumatic fever and post-streptococcal glomerulonephritis. Scarlet fever may present with a sandpaper papular rash and a strawberry tongue along with a sore throat. Rheumatic fever historically was a common cause of valvular heart disease, however incidence has significantly reduced with the introduction of antibiotic therapy. Poststreptococcal glomerulonephritis generally presents 1-2 weeks following onset of pharyngitis. The child will present with cola-coloured urine, periorbital edema, malaise, and decreased appetite. Treatment for poststreptococcal glomerulonephritis is beyond the scope of this podcast but it is important to note that treating Group A Strep pharyngitis does not prevent the complication of glomerulonephritis so to be aware of this in counseling and follow-up. In the past, these patients were readily referred for tonsillectomy but more recent evidence suggests that a child should have repeated confirmed strep infections before the benefits outweigh the risks of surgery. Far fewer children people are getting tonsillectomies today than before, but parents will still often request surgery. Current guidelines recommend tonsillectomy in a patient who has had 7 episodes in the past year, 5 episodes per year in the past 2 years or 3 episodes per year in the past 3 years, and all infections should be culture confirmed group A strep.

Each practice parameter and technical standard, representing a policy statement by the College, has undergone a thorough consensus process in which it has been subjected to extensive review and approval. Therefore, it should be recognized that adherence to the guidance in this document will not assure an accurate diagnosis or a successful outcome. All that should be expected is that the practitioner will follow a reasonable course of action based on current knowledge, available resources, and the needs of the patient to deliver effective and safe medical care.

Documentation that satisfies medical necessity includes 1) signs and symptoms and/or 2) relevant history (including known diagnoses). Additional information regarding the specific reason for the examination or a provisional diagnosis would be helpful and may at times be needed to allow for the proper performance and interpretation of the examination. Patient Selection the physician responsible for the examination should supervise patient selection and preparation and be available in person or by phone for consultation. Facility Requirements Appropriate emergency equipment and medications must be immediately available to treat adverse reactions associated with administered medications. Under certain clinical circumstances (uncooperative or pediatric patients), very rapid acquisitions, such as echo planar imaging or single-shot fast spin-echo imaging, can be performed to obtain T2 information. Slice thickness, spatial resolution, signal-to-noise ratio, acquisition time, and contrast are all interrelated. The clinical significance of tissue deposition remains unknown, but most experts believe that gadolinium chelates are safe. Postcontrast images, when indicated, should be obtained in at least one plane but preferably in two or more perpendicular planes. Improvements in the receiver and data acquisition systems also allow for more rapid imaging. The requirements include, but are not limited to , specifications of maximum static magnetic strength, maximum rate of change of magnetic field strength (dB/dt), maximum radiofrequency power deposition (specific absorption rate), and maximum acoustic noise levels [242,243].

In contrast, one trait shared by virtually all tumor cells is altered (dysregulated) metabolism. Indeed, metabolism has been a focus of cancer research in the last few years, as many pathways long associated with tumor growth have been found to intersect metabolic pathways in the cell. Brain tumors are highly infiltrative, and surgery rarely removes all tumor cells, particularly from eloquent areas of the brain. Thus, these tumors often recur within 2 years of their original diagnosis and in the same general area as the primary tumor. The proximity of the recurrent tumor to the primary tumor often precludes the use of additional standard radiation therapy because of toxicity concerns (3). The identification of new therapeutic targets for malignant gliomas has focused on molecular targets, often those found through global analyses done by the Cancer Genome Atlas consortium (4) and other groups (5-8). Many pathways long known to be associated with tumor cell growth, escape from apoptosis, aggressive blood vessel formation (angiogenesis) and therapy resistance have now been linked to cellular metabolism (17). These connections, and others, suggest that targeting metabolic changes can and should be considered in the context of other, more classic therapeutic targets. A byproduct of this inflammation is the buildup of fluid around the tumor, or peritumoral edema, which is a frequent cause of morbidity and mortality in patients with gliomas. Dexamethasone is the current treatment of choice for peritumoral inflammation and edema, yet it comes with adverse side effects such as hyperglycemia, cardiovascular effects, osteoporosis, weight gain, insomnia, infection and cognitive effects which ultimately reduce the quality of life for patients (54, 55). Results also demonstrated that increasing blood ketones affects a number of tumor-related gene networks. This allows for the 7 hypothesis that the neuro-protective activity of blood ketones may also function to reduce the deleterious side effect of cranial radiation on normal brain. A recent publication showed that fasting, which elevates blood ketones, not only sensitizes many types of cancer cells to standard therapies but may promote the protection of normal tissue from the toxicity associated with radiation and chemotherapy (69). The goal of the study was to determine if dietary induced ketosis could decrease the availability of 8 glucose to disrupt tumor metabolism while maintaining the nutritional status of the patients. Of the 16 subjects, 5 were able to complete the 3-month treatment period and none of these patients experienced further tumor progression while on the diet (82). However, it should be noted that the composition of the diet is critical, and the ongoing support of a registered dietician well versed in its use can reduce the likelihood of adverse effects in humans.

The main options are prenatal diagnosis by amniocentesis or chorionic-villous biopsy which may then be followed by termination of an afected foetus allergy pollen count quality 400 mg quibron-t, or pre-implantation genetic diagnosis allergy to cold order quibron-t online now. The latter requires in vitro fertilization and embryos are then tested genetically to ascertain whether they carry the abnormal gene allergy forecast tokyo order quibron-t with visa. He has an expanding intra-abdominal haematoma and requires emergency laparotomy. He is able to tell you that he bleeds infrequently and has previously only received treatment for procedures or trauma-related bleeding. His last treatment was an infusion of desmopressin 3 years before for a dental extraction. While this might be sufcient for a minor procedure, it would not provide adequate cover here. Subsequently, the trough level should be maintained in the normal range until there is adequate wound healing. This can be achieved by means of repeated bolus injections or a continuous infusion with regular monitoring of levels. The cardiologists wish to carry out an angiogram but have noticed some abnormalities on the coagulation screen. The reptilase time is insensitive to heparin and so this possibility is excluded because the reptilase time is also prolonged. Other causes include an inhibitor of fbrinogen cleavage, such as fbrinogen degradation products, or a low albumin that causes an artifcial prolongation. Measurement of fbrinogen function, which is most commonly done by a Clauss assay, and protein level with an antigen assay are required. Dysfbrinogenaemias may be associated with bleeding or thrombotic complications and very rarely both in the same family. This is consistent with the decision to place her on lifelong warfarin after a single thrombotic episode. Therefore, the risk for the angiogram was primarily one of thrombosis rather than bleeding. As the patient does not himself have a history of venous thrombosis, he does not require anti-coagulation at the moment. However, he should stop smoking and one would need to consider using thromboprophylaxis during periods of increased risk in the future. He recalls that his sister was diagnosed with haemophilia some years ago in Poland. The sister is now in her late 20s and has had two children without any bleeding complications. Consider the most likely diagnosis and what advice would you give to this man if he needed to have major surgery. However, he has normal levels of all the clinically relevant intrinsic factors and there is no history of bleeding either in himself or his sister. Therefore, the most likely diagnosis is a clinically insignifcant abnormality in the contact system. The patient had mistakenly assumed that because his sister had been found to have an abnormality after testing in a haemophilia centre that was the diagnosis. The patient can be reassured that there is no risk of bleeding with a contact factor defciency and indeed, these are of no proven clinical signifcance. This has been getting progressively worse and he is admitted in A&E with a nosebleed that lasted for 2 hours. He also reports severe back pain and tenderness over his chest wall on the right side. Prior to this illness, he was ft and well and had undergone surgery on three occasions without any bleeding problems. Two tests for lupus are negative and so an anti-phospholipid antibody is efectively excluded. A consumptive coagulopathy is unlikely as the fbrinogen is normal and the platelet count is only mildly reduced. There is, however, a marked normocytic anaemia and along with symptoms of bone pain, this makes myeloma the likely diagnosis. Subsequently, protein electrophoresis showed an IgM paraprotein with immunoparesis. Chest x-ray shows lytic lesions in the ribs on the right side and a spine x-ray shows vertebral collapse. Despite packing of the nose, there is recurrent nosebleeds and fresh bruising the day after admission. Usually, these symptoms do not require specifc treatment and standard treatment of the myeloma with subsequent reduction in paraprotein levels is sufcient to alleviate the bleeding symptoms. The most efective treatment is often removal of the paraprotein with plasma exchange. She had a normal, non-instrumental vaginal delivery and was discharged on the frst post-partum day with little lochia. Shortly after admission, she has a ft and requires treatment with anti-convulsants. As we know that the platelet count was normal prior to delivery, the most likely diagnosis is thrombotic thrombocytopenic purpura. This condition has an increased incidence in the peri-partum and would explain the neurological symptoms. Other acquired causes of thrombocytopenia would generally be associated with abnormal coagulation as part of a consumptive coagulopathy. Micro-angiopathic haemolytic anaemia can be demonstrated by the presence of red cell fragments on blood flm examination and raised bilirubin levels. The pentad of features classically seen in full-blown forms of the disease include renal impairment and so measurement of U&E is essential. Inhibitory antibodies can diferentiate between the congenital and acquired forms of the disease. Daily plasma exchanges should be continued until a minimum of 2 days after normalisation of the platelet count. In the last 6 months, her family had noticed on numerous occasions unexplained bruises up to 20 cm across and suspected the staf in the home of physical abuse. Although physical abuse might account for the bruising, it would not explain the oral bleeding. The most likely diagnosis is an acquired platelet dysfunction and so tests of platelet function such as platelet aggregometry and platelet nucleotide assays are required. The aggregometry traces are abnormal with an absence of the response to arachidonic acid being the most signifcant abnormality. The most likely explanation is that the patient is taking aspirin or a similar medication. In this case, it subsequently became clear that another resident in the care home had been administering aspirin to treat low back pain. There is no signifcant past medical history or family history and her only medication is a combined oral contraceptive that she has been taking for 3 years. However, the bleeding risk is signifcantly higher on thrombolysis and this needs to be carefully monitored, so safety may prevent its use in a non-specialist setting. Elevated D-dimer levels after the discontinuation of anti-coagulation are associated with an increased risk of recurrence. There is little value in repeating the ultrasound scan after completing treatment as many patients have residual abnormalities and this does not add anything further to estimating the risk of recurrence. There is a reasonable argument for long-term anti-coagulation in patients with extensive initial thrombus if the bleeding risk with anti-coagulation is low, as it would be in this case. Thrombophilia testing is most likely to reveal pertinent fndings in patients with a frst episode of unprovoked thrombosis below the age of 40 or those with a positive family history. Although this patient is under 40, there are provoking factor(s) and so thrombophilia testing is unlikely to be of value in this setting. She consults a doctor who carries out a thrombophilia screen from which the only result of interest is that she is heterozygous for Factor V Leiden. Five years later, she is complaining of intermittent pain and swelling in her left leg such that by the end of the day she fnds it difcult to stand. Data from the anti-coagulant clinic shows that her time in therapeutic range was 45% in the frst year of anti-coagulation and has been 65% since. The D-dimer level is now 450 ng/mL and a further scan shows chronic residual thrombus with recanalization and some varicosities in the proximal veins. In some cases, where it is likely to have been a signifcant causative factor there might be value in screening of family relatives. In this case, it is unlikely to have been a major causative factor and so the risk of thrombosis in frst degree relatives of the index case is increased whether or not they have Factor V Leiden. Although anti-coagulation reduces the risk of this complication, the use of graduated compression stockings is of more value in treating the symptoms. His father died suddenly of unknown causes at the age of 46 and his 27-year-old sister sufered a deep vein thrombosis during pregnancy. As the clinical suspicion is high a D-dimer is not of diagnostic value and a Doppler ultrasound should be done to confrm this. The illustration shows the presence of thrombus in the deep veins of the calf and popliteal region with extensive collaterals. He should be screened for the presence of a familial or acquired hypercoagulable state after the initial course of anti-coagulation is completed. Homozygosity occurs in about 1 in 5000 and carries a much greater risk of thrombosis (approximately 20-fold increased risk). The risk of recurrence does appear to be increased with severe thrombophilias and so long-term anti-coagulation would be recommended in this case. Should she turn out to be homozygous then long-term anti-coagulation would need to be considered. However, if she is heterozygous then thromboprophylaxis during periods of increased risk, rather than on-going anti-coagulation, would be appropriate. She developed a pulmonary embolism aged 35 after internal fxation of a fracture of femur and was anti-coagulated for 6 months. However, this risk may be outweighed by other benefts such as a reduction in the risk of osteoporosis. In this case, the absolute risk of recurrence is low as the single thrombotic episode was associated with a transient provoking factor. In this case, a preparation with a low dose of oestrogen or a transdermal preparation would be preferable. There is a history of two previous miscarriages at 10 and 22 weeks of gestation and one normal vaginal delivery. There is no personal or family history of thrombosis and there is no other past medical history of note. Protein S is bound by C4b-binding protein and it is the free (non-bound) fraction that is functionally active. Total protein S levels are measured by an antigen assay while the free fraction can be measured by both coagulationbased bioassay and antigen assays using an antibody specifc for the free fraction. However, functional assays can give falsely reduced levels in the presence of Factor V Leiden. In this case, only the functional protein S assay is reduced and the patient is heterozygous for Factor V Leiden which is the most likely explanation for the low level. She was anti-coagulated for 6 months and subsequently diagnosed with anti-thrombin defciency. Her only treatment since then has been prophylactic doses of low-molecular weight heparin prior to fying. The risk of thrombosis rises steadily during pregnancy although there is normally no change in antithrombin levels. This patient requires thromboprophylaxis during pregnancy and the main issue is whether this should be for the whole or part of the pregnancy. During early pregnancy, the use of anti-coagulants is associated with an increased risk of bleeding and so this decision needs to be made in conjunction with the obstetricians. If there are obstetric concerns regarding the risk of bleeding a reasonable compromise here is to initiate a prophylactic dose of low-molecular weight heparin in the third trimester. The medication can be discontinued when labour commences and restarted after delivery. If there is no post-partum bleeding, the thromboprophylaxis should be continued for a minimum of 6 weeks after delivery. There is considerable debate regarding the value of anti-Xa monitoring with no clear evidence indicating what anti-Xa level to aim for. Antithrombin defciency might be associated with resistance to heparins and so monitoring is generally advocated in these cases. He has no signifcant personal history but there is a strong family history of thrombosis. He was diagnosed with anti-thrombin defciency and is now on lifelong anti-coagulation with warfarin. In this case, molecular analysis confrmed heterozygosity for a mutation in the anti-thrombin gene that had previously been described in a family with thrombosis at an early age.
