TL;DR: A combination of oral isoprinosine (Inosiplex) and intraventricular interferon alfa appears to be the best effective treatment for subacute sclerosing panencephalitis.
Abstract: Subacute sclerosing panencephalitis (SSPE) is a progressive neurological disorder of childhood and early adolescence. It is caused by persistent defective measles virus. Brain biopsies or postmortem histopathological examination show evidence of astrogliosis, neuronal loss, degeneration of dendrites, demyelination, neurofibrillary tangles, and infiltration of inflammatory cells. Patients usually have behavioral changes, myoclonus, dementia, visual disturbances, and pyramidal and extrapyramidal signs. The disease has a gradual progressive course leading to death within 1-3 years. The diagnosis is based upon characteristic clinical manifestations, the presence of characteristic periodic EEG discharges, and demonstration of raised antibody titre against measles in the plasma and cerebrospinal fluid. Treatment for SSPE is still undetermined. A combination of oral isoprinosine (Inosiplex) and intraventricular interferon alfa appears to be the best effective treatment. Patients responding to treatment need to receive it life long. Effective immunisation against measles is the only solution presently available to the problem of this dreaded disease.

TL;DR: The availability of complete genome sequences for several bacterial pathogens coupled with bioinformatics will lead to significant advances toward the identification and characterisation of all these different strategies for bacterial disease.
Abstract: Pathogenic bacteria utilise a number of mechanisms to cause disease in human hosts. Bacterial pathogens express a wide range of molecules that bind host cell targets to facilitate a variety of different host responses. The molecular strategies used by bacteria to interact with the host can be unique to specific pathogens or conserved across several different species. A key to fighting bacterial disease is the identification and characterisation of all these different strategies. The availability of complete genome sequences for several bacterial pathogens coupled with bioinformatics will lead to significant advances toward this goal.

TL;DR: Chronic subdural haematoma is predominantly a disease of the elderly that usually follows a minor trauma and the common manifestations are altered mental state and focal neurological deficit.
Abstract: Chronic subdural haematoma is predominantly a disease of the elderly. It usually follows a minor trauma. A history of direct trauma to the head is absent in up to half the cases. The common manifestations are altered mental state and focal neurological deficit. Neurological state at the time of diagnosis is the most important prognostic factor. Morbidity and mortality is higher in the elderly but outcome is good in patients who undergo neurosurgical intervention.

TL;DR: Pulmonary arteriovenous malformations (PAVM) are rare pulmonary vascular anomalies that can cause dyspnoea from right-to-left shunt and various central nervous system complications have been described including stroke and brain abscess.
Abstract: Pulmonary arteriovenous malformations (PAVM) are rare pulmonary vascular anomalies. Although most patients are asymptomatic, PAVMs can cause dyspnoea from right-to-left shunt. Because of paradoxical emboli, various central nervous system complications have been described including stroke and brain abscess. There is a strong association between PAVM and hereditary haemorrhagic telangiectasia. Chest radiography and contrast enhanced computed tomography are essential initial diagnostic tools but pulmonary angiography is the gold standard. Contrast echocardiography is useful for diagnosis and monitoring after treatment. Most patients should be treated. Therapeutic options include angiographic embolisation with metal coil or balloon occlusion and surgical excision.

TL;DR: With few exceptions (for example, aciclovir for HSE), no specific therapy is available for most forms of viral encephalitis, and better antiviral therapy is needed to meet the challenge of acute viralEncephalitis more effectively.
Abstract: Acute encephalitis constitutes a medical emergency. In most cases, the presence of focal neurological signs and focal seizures will distinguish encephalitis from encephalopathy. Acute disseminated encephalomyelitis is a non-infective inflammatory encephalitis that may require to be treated with steroids. Acute infective encephalitis is usually viral. Herpes simplex encephalitis (HSE) is the commonest sporadic acute viral encephalitis in the Western world. Magnetic resonance imaging of brain is the investigation of choice in HSE and the diagnosis may be confirmed by the polymerase chain reaction test for the virus in the cerebrospinal fluid. In this article, we review the diagnosis, investigations, and management of acute encephalitis. With few exceptions (for example, aciclovir for HSE), no specific therapy is available for most forms of viral encephalitis. Mortality and morbidity may be high and long term sequelae are known among survivors. The emergence of unusual forms of zoonotic encephalitis has posed an important public health problem. Vaccination and vector control measures are useful preventive strategies in certain arboviral and zoonotic encephalitis. However, we need better antiviral therapy to meet the challenge of acute viral encephalitis more effectively.

TL;DR: When diagnosis is delayed, complications of a retained foreign body such as unresolving pneumonia, lung abscess, recurrent haemoptysis, and bronchiectasis may necessitate a surgical resection, so a preoperative flexible bronchoscopy should always be considered in suitable cases.
Abstract: Foreign body aspiration is a worldwide health problem which often results in life threatening complications. More than two thirds of foreign body aspirations occur among children younger than 3 years. Organic materials such as nuts, seeds, and bones are most commonly aspirated. There is a wide range of clinical presentation, and often there is not a reliable witness to supply the clinical history, especially in children. Maintaining a high index of suspicion is therefore necessary for the diagnosis. None of the imaging methods employed in such cases are diagnostic, and bronchoscopy is frequently necessary for the diagnosis as well as the treatment. In adults, removal of the foreign body can be attempted during diagnostic examination with a fibreoptic bronchoscope under local anaesthesia, which may help to avoid any further invasive procedures with more complications. When diagnosis is delayed, complications of a retained foreign body such as unresolving pneumonia, lung abscess, recurrent haemoptysis, and bronchiectasis may necessitate a surgical resection. However, some of the late complications may resolve completely after the retrieval of the foreign body, therefore, a preoperative flexible bronchoscopy should always be considered in suitable cases.

TL;DR: New antibiotics have been recently released that add to the armamentarium for therapy against MRSA and include linezolid, and quinupristin/dalfopristin, but cost, side effects, and resistance may limit their long term usefulness.
Abstract: Methicillin resistant Staphylococcus aureus (MRSA) is a major nosocomial pathogen that causes severe morbidity and mortality worldwide. MRSA strains are endemic in many American and European hospitals and account for 29%–35% of all clinical isolates. Recent studies have documented the increased costs associated with MRSA infection, as well as the importance of colonisation pressure. Surveillance strategies have been proposed especially in high risk areas such as the intensive care unit. Pneumonia and bacteraemia account for the majority of MRSA serious clinical infections, but intra-abdominal infections, osteomyelitis, toxic shock syndrome, food poisoning, and deep tissue infections are also important clinical diseases. The traditional antibiotic therapy for MRSA is a glycopeptide, vancomycin. New antibiotics have been recently released that add to the armamentarium for therapy against MRSA and include linezolid, and quinupristin/dalfopristin, but cost, side effects, and resistance may limit their long term usefulness.

TL;DR: Investigation of 210 farmers bitten by the common krait in Anuradhapura found that Mortality could be minimised with early and free access to mechanical ventilation.
Abstract: Common krait (Bungarus caeruleus) is the deadliest snake found commonly in the dry zone of Sri Lanka. In Anuradhapura, 210 farmers bitten by the common krait over a three year period were investigated prospectively from 1 January 1996. The sex ratio was equal, 110 (52%) patients were in the age group 10–30 years. One hundred and one (48%) patients were severely envenomed and needed mechanical ventilation from 12 hours to 29 days (mode two days). The bite occurred at night while the victims were asleep on the floor. In 99 (47%) situations killed specimens were available for identification. The cardinal symptom was abdominal pain developing within hours of the bite. Alteration in the level of consciousness was observed in 150 (71%) patients: drowsy in 91 (43%), semiconscious in 24 (11%), and deep coma in 35 (17%). Autonomic disturbances included transient hypertension, tachycardia, lacrimation, sweating, and salivation. These manifested in 139 (66%) patients with moderate to severe envenomation. One hundred and forty nine (71%) had hypokalaemia and 105 (50%) metabolic acidosis, anterograde memory loss in 84 (40%), and delayed neuropathy in 38 (22%) patients. Polyvalent antivenom had no significant benefit (t = 0.5) in reversing respiratory paralysis and preventing delayed neurological complications. Sixteen (7.6%) patients died and a submucosal haemorrhage in the stomach was seen at necropsy in three cases. Mortality could be minimised with early and free access to mechanical ventilation.

TL;DR: Fifty two cases of tuberculosis of the breast encountered over a 15 year period and accounting for 3% of all breast lesions are reported, the classic presentation was a breast lump with associated sinus.
Abstract: Fifty two cases of tuberculosis of the breast encountered over a 15 year period and accounting for 3% of all breast lesions are reported. The classic presentation was a breast lump with associated sinus in 39%, isolated breast lump in 23%, sinus without lump in 12%, and tender nodularity in 23% of the patients. Associated axillary lymphadenopathy was found in 41%. Diagnosis was confirmed by fine needle aspiration cytology or histology in all the cases and antitubercular therapy formed the mainstay of treatment.

TL;DR: If, as seems likely, complex inherited and environmental factors contribute to the pathogenesis of MND, future treatment may involve a combination of molecular based treatments or restoration of cellular integrity using stem cell grafts.
Abstract: Motor neurone disease (MND), or amyotrophic lateral sclerosis (ALS), is a neurodegenerative disorder of unknown aetiology. Progressive motor weakness and bulbar dysfunction lead to premature death, usually from respiratory failure. Confirming the diagnosis may initially be difficult until the full clinical features are manifest. For all forms of the disease there is a significant differential diagnosis to consider, including treatable conditions, and therefore specialist neurological opinion should always be sought. Clear genetic inheritance has been demonstrated in a minority of patients with familial ALS but elucidation of the biological basis of genetic subtypes is also providing important information which may lead to treatments for sporadic forms of the disease. In the absence of curative or disease modifying therapy, management is supportive and requires a multidisciplinary approach. If, as seems likely, complex inherited and environmental factors contribute to the pathogenesis of MND, future treatment may involve a combination of molecular based treatments or restoration of cellular integrity using stem cell grafts.

TL;DR: The VAC system was found to be highly effective in controlling fistula effluent and in promoting healing of excoriated skin in all three patients and may also actually promote healing of the fistula.
Abstract: Methods: The results of using the VAC system were studied in three patients with moderate or high volume output enterocutaneous fistulae where conventional treatment had failed to prevent skin excoriation. Results: The VAC system was found to be highly effective in controlling fistula effluent and in promoting healing of excoriated skin in all three patients. Complete healing of the fistula was also achieved in two of the three patients. Conclusion: The VAC system can be an effective and economically viable method of containing fistula effluent and protecting the skin of patients with enterocutaneous fistulae. Contrary to conventional thought, the VAC system may also actually promote healing of the fistula.

TL;DR: It is recommended that all medical schools urgently incorporate training about common aspects of “generic” acute care in their curricula about knowledge and understanding of basic aspects of acute care.
Abstract: Deficiencies in trainees' knowledge, skills, and attitudes have the potential to influence the initial assessment, treatment, and outcome of acutely ill ward patients. Knowledge of basic aspects of acute care were assessed among a group of 185 trainee doctors at six hospitals. Many were unaware of the signs of total airway obstruction, confusing them with those of partial obstruction (pre-registration house officers (PRHOs) 11%, senior house officers (SHOs) 14%) or apnoea (PRHOs 47%, SHOs 26%). Knowledge about the use of non-rebreathing oxygen masks was poor; 23% of trainees could not describe the purpose of the reservoir bag or gave answers that were unclear or incorrect. Seven trainees thought that it was involved in humidification, or carbon dioxide collection or removal. Seventeen per cent of trainees could not quote the maximum deliverable inspired oxygen concentration provided by these masks or gave values below the normal range. Thirty one per cent of trainees thought that the lower end of the normal range for pulse oximetry (S(p)O(2)) was below 95%; nine (5%) believed it to be below 90%. There was also poor knowledge of the factors influencing the function of a pulse oximeter. Similar deficits in knowledge and understanding existed in relation to the normal capillary refill time, minimum hourly urine output, the use of the AVPU scale and the role of blood glucose testing in unconscious adults. Only 22% of PRHOs and 21% of SHOs identified the correct percentage hospital survival for patients who suffer an in-hospital cardiac arrest. Knowledge of aspects of consent was unsatisfactory. It is recommended that all medical schools urgently incorporate training about common aspects of "generic" acute care in their curricula.

TL;DR: Coeliac disease is now presenting more commonly without gastrointestinal symptoms and often to specialties other than gastroenterology, although more cases are diagnosed, this may be a reflection of increasing recognition rather than a true increase in incidence.
Abstract: Objective: To determine the incidence and presenting features of adult coeliac disease in a single university hospital in South Yorkshire. Design: A retrospective case finding study. Data were obtained from pathology and immunology databases, clinical notes, dietetic records, and patient questionnaires. Setting: Royal Hallamshire Hospital in South Yorkshire, England. Participants: All recorded cases of coeliac disease. Main outcome measures: Crude annual incidence rates for coeliac disease was obtained. The numbers of coeliac antibody profiles requested per year from the Royal Hallamshire Hospital were ascertained. Age at diagnosis, sex, year of diagnosis, presenting symptoms, associated conditions, and delay in diagnosis was documented. In addition the specialty of the clinician who made the diagnosis was noted. Results: There were 264 cases in total (male n=86, ratio 1:2). Mean age at diagnosis was 44.9 years (range 1–82, median 44.5). A trend was observed from 1990 to 2000 inclusive, of an annual increase in the incidence of coeliac disease. There has been a coincidental increase in the measurement of associated antibodies. Although 28.4% of patients presented with gastrointestinal symptoms, 20.1% had iron deficiency anaemia. The ratio of typical to atypical symptoms was 1:2.5. (single sample test of proportions p<0.001). The diagnosis was made by a gastroenterologist in only 52.7% of cases. The median duration of symptoms before the diagnosis of coeliac disease was 4.9 years (range 0.25–16 years). Conclusion: Coeliac disease is now presenting more commonly without gastrointestinal symptoms and often to specialties other than gastroenterology. Although more cases are diagnosed, this may be a reflection of increasing recognition rather than a true increase in incidence.

TL;DR: In Victorian times, Simpson championed chloroform anaesthesia, Lister pioneered antisepsis, and caesarean section was introduced, however, Britain's maternal mortality rate fell dramatically after antibiotics appeared and is now 11.4%.
Abstract: Obstetric intervention originally consisted of extraction of the baby, usually by the breech, to save the mother's life in obstructed labour. Forceps, introduced in the 17th century, were later refined by men-midwives like William Smellie. In Victorian times, Simpson championed chloroform anaesthesia, Lister pioneered antisepsis, and caesarean section was introduced. In 1935, however, Britain's maternal mortality rate was still around 400/100,000. It fell dramatically after antibiotics appeared and is now 11.4. In the 1960s ultrasound and electronic fetal monitoring became widely used. In 2000 the British caesarean section rate reached 20%. Worldwide, childbirth still causes 600,000 maternal deaths a year.

TL;DR: The aim of the present review is to integrate the experiences derived from different outbreaks around the world, caused by different Trichinella species, in order to provide a more comprehensive approach to diagnosis and treatment.
Abstract: Trichinellosis is a re-emerging zoonosis and more clinical awareness is needed. In particular, the description of new Trichinella species such as T papuae and T murrelli and the occurrence of human cases caused by T pseudospiralis, until very recently thought to occur only in animals, requires changes in our handling of clinical trichinellosis, because existing knowledge is based mostly on cases due to classical T spiralis infection. The aim of the present review is to integrate the experiences derived from different outbreaks around the world, caused by different Trichinella species, in order to provide a more comprehensive approach to diagnosis and treatment.

TL;DR: The risk of permanent damage to the ovaries after ablative radioiodine treatment appears to be low and patients can be reassured they can have normal pregnancies after this treatment.
Abstract: The aim of this study was to review the outcome of ablative radioiodine treatment on ovarian function in young women treated for differentiated thyroid carcinoma. Of 1398 patients with differentiated thyroid cancer, 496 were women under the age of 40 at the time of diagnosis who had received radioiodine therapy. Of these, 322 received a single 3 GBq ablation dose of radioiodine while the remainder received subsequent treatment with 131I with a cumulative activity of 8.5–59 GBq for residual, recurrent, or metastatic disease. Transient amenorrhoea or menstrual irregularities lasting up to 10 months were experienced in 83 patients (17%). No cases of permanent ovarian failure were recorded. There were 427 children born to 276 women; only one patient wishing to achieve a successful pregnancy outcome has been unsuccessful. Four premature births and 14 miscarriages occurred but no congenital abnormalities were reported. The risk of permanent damage to the ovaries after ablative radioiodine treatment appears to be low and patients can be reassured they can have normal pregnancies after this treatment.

TL;DR: A straightforward assessment of footwear in older people could improve comfort and avoid preventable foot disorders and an association was found between ill fitting shoes and self reported pain, and between illfitting shoes and ulcer formation.
Abstract: Background: Foot health is an important issue in older people. Inappropriate shoes increase the risk of callous and ulcer formation, as well as increasing the risk of falls. There are no data defining the size of this problem. Objective: The aim of the study was to investigate the proportion of elderly people on a general rehabilitation ward wearing incorrectly sized shoes and to look for the presence of complications. Methods: Sixty five consecutive patients (mental state questionnaire score >6) admitted to a rehabilitation ward had their foot length and width measured, and the size of their current footwear recorded. Sensation was tested with a standard 10 g monofilament. The presence of ulceration was noted. Foot pain was recorded by the patient on a visual analogue scale. Any history of diabetes mellitus, peripheral vascular disease, or peripheral neuropathy was noted. Results: The median age of the subjects was 82 (range 64–93). Six (9%) had a history of diabetes, seven (11%) had symptomatic peripheral vascular disease, and 17 (26%) had sensory impairment. Ten patients (15%) had foot ulceration present, and 47 patients (72%) had ill fitting shoes (a discrepancy in length of more than half a British shoe size fitting or more than one British width fitting, 7 mm). Incorrect shoe length was significantly associated with the presence of ulceration (odds ratio (OR) = 10.04, p = 0.016). Presence of ulceration was significantly associated with a history of peripheral vascular disease (OR = 11.56, p = 0.008). Pain was significantly associated with incorrect shoe length (p = 0.0238) and with sensory impairment (p = 0.0314). Conclusion: Most older people on a rehabilitation ward wore ill fitting shoes. An association was found between ill fitting shoes and self reported pain, and between ill fitting shoes and ulcer formation. A straightforward assessment of footwear in older people could improve comfort and avoid preventable foot disorders.

TL;DR: Though no antiviral drug is available against JE, effective supportive management can improve the outcome and control of JE involves efficient vector control and appropriate use of vaccines.
Abstract: One of the leading causes of acute encephalopathy in children in the tropics is Japanese encephalitis (JE). Transmitted by the culex mosquito, this neurotropic virus predominately affects the thalamus, anterior horns of the spinal cord, cerebral cortex, and cerebellum. It mainly affects children <15 years and is mostly asymptomatic. The occasional symptomatic child typically presents with a neurological syndrome characterised by altered sensorium, seizures, and features of intracranial hypertension. Aetiological diagnosis is based on virus isolation or demonstration of virus specific antigen or antibodies in the cerebrospinal fluid/blood. Though no antiviral drug is available against JE, effective supportive management can improve the outcome. Control of JE involves efficient vector control and appropriate use of vaccines.

TL;DR: Non-suppurative BCG lymphadenitis is best managed with expectant follow ups only, because medical treatment with erythromycin or antituberculous drugs do not hasten the regression or prevent development of suppuration.
Abstract: Bacille Calmette-Guerin (BCG) lymphadenitis is the most common complication of BCG vaccination. Two forms of BCG lymphadenitis can be recognised in its natural course-simple or non-suppurative lymphadenitis, which usually regresses spontaneously over a period of few weeks, and suppurative BCG lymphadenitis distinguished by the development of fluctuations in the swelling, with erythema and oedema of overlying skin. Healing in suppurative glands occurs through spontaneous perforation and sinus formation, followed by closure of the sinus by cicatrisation. Non-suppurative BCG lymphadenitis is best managed with expectant follow ups only, because medical treatment with erythromycin or antituberculous drugs do not hasten the regression or prevent development of suppuration. Suppurative BCG lymphadenitis may be treated by needle aspiration to hasten resolution and prevent spontaneous perforation and sinus formation. Surgical excision is rarely needed and is meant for cases of failed needle aspiration or for draining BCG nodes.

TL;DR: Inability to learn an adequate inhaler technique in subjects with a normal AMT score appears to be due to unrecognised cognitive impairment or dyspraxia, and the MMT is probably a more useful screening test than the AMt score in this context.
Abstract: Clinical observations have shown that some older patients are unable to learn to use a metered dose inhaler (MDI) despite having a normal abbreviated mental test (AMT) score, possibly because of dyspraxia or unrecognised cognitive impairment. Thirty inhaler-naive inpatients (age 76-94) with an AMT score of 8-10 (normal) were studied. Standard MDI training was given and the level of competence reached was scored (inhalation score). A separate observer performed the minimental test (MMT), Barthel index, geriatric depression score (GDS), ideational dyspraxia test (IDT), and ideomotor dyspraxia test (IMD). No correlative or threshold relationship was found between inhalation score and Barthel index, GDS, or IDT. However, a significant correlation was found between inhalation score and IMD (r = 0.45, p = 0.039) and MMT (r = 0.48, p = 0.032) and threshold effects emerged in that no subject with a MMT score of less than 23/30 had an inhalation score of 5/10 or more (adequate technique requires 6/10 or more), and all 17/18 with an inhalation score of 6/10 or more had an IMD of 14/20 or more. The three patients with a MMT >22 and inhalation score <6 had abnormal IMD scores. Inability to learn an adequate inhaler technique in subjects with a normal AMT score appears to be due to unrecognised cognitive impairment or dyspraxia. The MMT is probably a more useful screening test than the AMT score in this context.

TL;DR: The treatment of advanced disease is still essentially palliative, although surgery for limited hepatic metastases may be curative in a small proportion of patients, and adjuvant radiotherapy and chemotherapy have important parts to play.
Abstract: Colorectal cancer is the second most common cause of cancer death in the UK. Prompt investigation of suspicious symptoms is important, but there is increasing evidence that screening for the disease can produce significant reductions in mortality. High quality surgery is of paramount importance in achieving good outcomes, particularly in rectal cancer, but adjuvant radiotherapy and chemotherapy have important parts to play. The treatment of advanced disease is still essentially palliative, although surgery for limited hepatic metastases may be curative in a small proportion of patients.

Journal ArticleDOI
TL;DR: In patients with severe symptoms, a trial of 4–6 weeks’ treatment with quinine is probably still justified, but the efficacy of treatment should be monitored, for example using a sleep and cramp diary.
Abstract: Nocturnal leg cramps are common in older people. Such cramps are associated with many common diseases and medications. Physiological methods may be useful for preventing cramps in some people, but there have been no controlled trials of these approaches. Quinine is moderately effective in preventing nocturnal leg cramps. However, there are concerns about the risk/benefit ratio with this drug. In patients with severe symptoms, a trial of 4-6 weeks' treatment with quinine is probably still justified, but the efficacy of treatment should be monitored, for example using a sleep and cramp diary.

TL;DR: The case report in this review illustrates an acute myocardial infarction in a young adult probably due to arterial thrombosis that can be attributed to a hypercoagulable state resulting from the nephrotic syndrome.
Abstract: The case report in this review illustrates an acute myocardial infarction in a young adult probably due to arterial thrombosis that can be attributed to a hypercoagulable state resulting from the nephrotic syndrome. Although rare, acute myocardial infarction should be considered in young adults presenting with chest pain. A detailed clinical history may help to identify the aetiology, and guide subsequent management, but diagnostic coronary angiography is essential. Careful risk factor modification and treatment of the underlying cause should reduce the incidence of recurrent cardiac events.

TL;DR: A general outline of the hyperemesis gravidarum, its relation to the gastrointestinal system and thyroid, mild and rare severe complications, and conventional treatment versus newer options are discussed.
Abstract: Hyperemesis gravidarum is a common problem for an obstetrician. Though nausea and vomiting are quite common in pregnancy, hyperemesis is found in only 1-20 patients per 1000. In this practical review, a general outline of the syndrome, its relation to the gastrointestinal system and thyroid, mild and rare severe complications, and conventional treatment versus newer options are discussed.

TL;DR: To determine the normal range for carbon monoxide concentrations in the exhaled breath of subjects in the emergency department and to develop a protocol for the use of a breath analyser to detect abnormalcarbon monoxide exposure, breath analysis was rapid and results correlated well with carbon Monoxide exposure.
Abstract: Objectives: To determine the normal range for carbon monoxide concentrations in the exhaled breath of subjects in the emergency department and to develop a protocol for the use of a breath analyser to detect abnormal carbon monoxide exposure. Methods: A hand held breath analyser was used to measure end expiratory carbon monoxide concentrations in 382 consenting subjects. Questionnaire data were collected to assess the effect of common sources of carbon monoxide exposure on breath carbon monoxide levels. Smokers were used as a carbon monoxide exposed group for comparison with non-smokers. Results: The range of carbon monoxide concentrations obtained in the non-smoking group was 0–6 ppm and in the smoking group was 1–68 ppm. Smokers had a mean breath carbon monoxide concentration of 16.4 ppm and non-smokers had a mean of 1.26 ppm (95% confidence interval (CI) for difference 13.6 to 16.8 ppm). Male sex and frequent motor vehicle use were associated with slightly higher carbon monoxide concentrations (by 0.40, 95% CI 0.18 to 0.63 ppm, and 0.38, 95% CI 0.13 to 0.63 ppm, respectively) in the non-smoking group. Mean breath carbon monoxide concentrations increased in direct proportion to the number of cigarettes smoked (p Conclusions: Breath analysis was rapid and results correlated well with carbon monoxide exposure. In this population subjects with breath carbon monoxide concentrations greater than 6 ppm should be assessed for the risk of carbon monoxide poisoning. However even carbon monoxide concentrations less than 6 ppm do not exclude carbon monoxide poisoning within the last 24 hours.

TL;DR: There is a need for evidenced based successful fall prevention strategies but this study also reinforces an urgent public health message that an alternative to benzodiazepines should be sought for night sedation for older patients.
Abstract: Objective: To explore risk factors associated with falls and to evaluate a strategy used by nurses to predict and prevent falls in a hospitalised cohort of elderly patients. Design: A case-control study of risk factors for falls in hospital. Setting: A district general hospital in the UK. Subjects: Altogether 181 patients in an acute integrated medical unit who had fallen were matched for age with 181 patients in the next bed who had not fallen. Results: It was found that 46% (84 of 181) of the fallers were taking one or more benzodiazepines compared with 27% (48 of 181) of the control patients (p Conclusion: There is a need for evidenced based successful fall prevention strategies but our study also reinforces an urgent public health message that an alternative to benzodiazepines should be sought for night sedation for older patients.

TL;DR: The effect of pregnancy on the outcome ofmultiple sclerosis is reviewed and the management of pregnant women who have multiple sclerosis is discussed.
Abstract: Multiple sclerosis causes disability in young adults and, like most autoimmune diseases, affects women more commonly than men. The disease can therefore present at a time when many have, or are considering, starting a family. The effect of pregnancy on the outcome of multiple sclerosis is reviewed and the management of pregnant women who have multiple sclerosis is discussed.

TL;DR: The identification of risk factors for perforation would allow primary public health prevention, secondary risk factor modification, and early prophylactic surgery to be aimed at people at high risk.
Abstract: Perforated colonic diverticular disease results in considerable mortality and morbidity. This review appraises existing evidence on the epidemiology and mechanisms of perforation, highlights areas of further study, and suggests an epidemiological approach towards preventing the condition. Computerised searches were used to identify published articles relating to the epidemiology, pathophysiology, and clinical features of perforated colonic diverticular disease. Several drug and dietary exposures have potential biological mechanisms for causing perforation. Of these only non-steroidal anti-inflammatory drugs have been consistently identified as risk factors in aetiological studies. The causes of perforated colonic diverticular disease remain largely unknown. Further aetiological studies, looking specifically at perforation, are required to investigate whether cause-effect relationships exist for both drug and dietary exposures. The identification of risk factors for perforation would allow primary public health prevention, secondary risk factor modification, and early prophylactic surgery to be aimed at people at high risk.

TL;DR: A case of necrotising fasciitis in a patient receiving infliximab, an antitumour necrosis factor alpha (TNF-α) agent for rheumatoid arthritis, is presented, highlighting the risk of severe sepsis in patients on anti-T NF-α treatment.
Abstract: A case of necrotising fasciitis in a patient receiving infliximab, an antitumour necrosis factor alpha (TNF-alpha) agent for rheumatoid arthritis, is presented. A widespread confluent, erythematous, pustular skin rash was the presenting sign. There was no fever throughout this admission. beta-Haemolytic group A streptococcus was isolated from blood cultures and skin swabs. The adductor muscles and fascia around the site of a previous hip arthroplasty were necrotic on exploration. The case highlights the risk of severe sepsis in patients on anti-TNF-alpha treatment.
