Osteoporosis and genetic influence: a three-generation study
Authors: Kahn S A , Pace J E , Cox M L , Gau D W , Cox S A , Hodkinson H M 
Published: December 2008

Summary
We have studied 27 triads of mother, daughter and grandmother for possible genetic influence on distal and proximal forearm bone density, measured by single photon absorptiometry.
We found a significant correlation of bone density at the proximal forearm between the mothers and grandmothers (r = 0.499, P &lt; 0.01). There was also a weak correlation between proximal forearm bone densities of mothers and daughters (r = 0.327, P &lt; 0.1).
Significant correlations were found between the three generations for grip strength, pedometry, height and triceps skinfold thickness. There was also significant correlation between mother and grandmother for alcohol intake. There was no correlation for contraceptive pill use, smoking, dietary calcium intake, body weight or body mass index.
The study concludes that, although there are similarities in bone mineral content between the three generations, genetic factors cannot be conclusively proven to be the major determinant of bone density. Lifestyle and environmental factors may have a bearing on achieving the peak bone mass and subsequent development of osteoporosis.
Creatine kinase isoform electrophoresis for the early confirmation of myocardial infarction detected by timed sequential CK slope analysis
Authors: Chattington Paula , Clarke D , Neithercut W D 
Published: December 2008

Summary
Creatine kinase (CK)-MM and -MB isoforms were evaluated for the early diagnosis of myocardial infarction in patients aged over 65 years admitted to a district general hospital with acute chest pain.
Samples were collected for standard cardiac enzymes, timed CK slope analysis, and CKMM and CKMB isoform analysis from 48 patients admitted with acute chest pain. CKMM and CKMB isoform analyses were conducted using a Helena Rep electrophoresis system under standard conditions supplied by the company. In addition to the results of the biochemical tests the discharge diagnosis of the patients were also recorded.
CKMM isoform analysis resulted in three false-negative classifications of patients and one false-positive. The predictive value of this test was 100% for a positive result and 94% for a negative result. CKMB isoform analysis was less accurate and there were six false-negative results and five false-positive results. The predictive value of a positive result was 75% and 85% for a negative result. CK isoform analysis became unreliable when mean total CK levels in serum were 210 IU/l (+/- 171).
CK isoform analysis may be of use in the investigation of patients whose samples have a total CK concentration greater than the reference range but was no better than timed CK slope analysis for the detection of myocardial infarction in patients aged more than 65 years.

Published: December 2008

Summary
We present a case of erythromelalgia in a 68 year old lady who responded, within 48 hours, to a twice daily topical application of capsaicin cream 0.025%. Capsaicin cream was stopped after 2 months, and 6 months later the patient continued to have the symptomatic relief she experienced initially.
Orthostatic hypotension and anti-hypertensive therapy in the elderly
Authors: Fotherby M D , Potter J F 
Published: December 2008

Summary
The effect of withdrawing or continuing anti-hypertensive therapy on orthostatic blood pressure change in elderly hypertensive subjects was examined. Subjects meeting criteria for therapy withdrawal had supine and standing blood pressure measurements taken on treatment, and at 1, 3, 6, 9 and 12 months off treatment whilst receiving standard non-pharmacological advice to lower blood pressure. Subjects not meeting blood pressure criteria for treatment withdrawal or were unwilling to stop treatment had blood pressure measurements taken after 6 and 12 months whilst also receiving non-pharmacological advice. Orthostatic hypotension was defined as a mean systolic blood pressure fall &gt; or = 20 mmHg on standing from a supine position.
Forty-seven subjects (median age 76 years, range 65-84 years) had treatment withdrawn. Thirteen subjects (median age 73 years, range 68-82 years) continued on their treatment. Twelve months after treatment withdrawal there was a significant reduction in the number demonstrating orthostatic hypotension from 11 (23%) to four (11%) (P &lt; 0.05), whilst the group continuing on treatment showed no change. In the withdrawal group those with orthostatic hypotension on treatment (n = 11) were older (79 versus 74 years, P = 0.05), had higher prewithdrawal systolic blood pressure (164 +/- 21 versus 147 +/- 17 mmHg, P = 0.02) compared to those without, although there was no difference in body mass index, gender, number or type of anti-hypertensive drugs taken. In elderly hypertensive subjects withdrawal of anti-hypertensive therapy and institution of non-pharmacological treatment can over several months reduce the prevalence of orthostatic hypotension.
Adults with spina bifida and/or hydrocephalus
Authors: Morgan D J R , Blackburn M , Bax M 
Published: December 2008

Summary
Recent advances in medical technology enable many children with complex disabilities to survive into adulthood and to have certain expectations of life. One of these expectations is the continuity of specialist health care in an adult setting. This paper describes a new out-patient service which aims to provide optimum care, continuity and consistency of service for adults with spina bifida and/or hydrocephalus. The need for specialist health input into this service, in order to monitor the neurological, urological and psychosocial complications often associated with spina bifida and/or hydrocephalus is recognised. In one year (1992), 86 young adults with spina bifida and/or hydrocephalus attended for annual or more frequent assessment, either independently or with their families or carers. A variety of health and social problems were treated. In response to demand, a multi-disciplinary assessment unit, which includes the services of both medical and nursing specialists, occupational and physiotherapists, psychologists and access to specialist surgical opinions has recently opened at the Chelsea and Westminster Hospital. This new service attempts to meet some of the needs described in the outpatient audit. Adults with other disabilities are requesting to use this service. A longitudinal study to monitor quality, and outcome is indicated from this initial survey.
Survival in hypercalcaemic patients with cancer and co-existing primary hyperparathyroidism
Authors: Hutchesson A C J , Bundred N J , Ratcliffe W A 
Published: December 2008

Summary
Hypercalcaemia associated with malignancy is generally thought to carry a poor prognosis. Of 47 consecutive patients with hypercalcaemia and malignancy, serum parathyroid hormone (PTH) was elevated in seven, consistent with co-existing hyperparathyroidism. Median survival from onset of hypercalcaemia in these seven patients was 817 days; compared to 33 days in the remaining 40 patients with hypercalcaemia of malignancy, in whom PTH was suppressed (p = 0.007). Among patients with hypercalcaemia of malignancy, plasma PTH-related protein (PTHrP) concentration showed no correlation with survival (r2 = 2.1%), but one patient with increased levels of both PTH and PTHrP survived only nine days after the onset of hypercalcaemia. A raised PTH had a positive predictive value of 86% for survival &gt; 100 days, and of 71% for survival &gt; 1 year. A raised plasma PTHrP predicted death within 100 days with a positive predictive value of 69%. We conclude that measurement of serum PTH is indicated in patients with hypercalcaemia and malignancy to identify the 15% with hyperparathyroidism, since this is associated with prolonged survival. In patients with hyperparathyroidism, assay of plasma PTHrP may indicate concurrent hypercalcaemia of malignancy, with an associated poor prognosis.
Endocarditis due to high-level gentamicin-resistant Enterococcus faecalis
Authors: Lee P Y C , Das S S 
Published: December 2008

Abstract
We report a case of aortic valve endocarditis caused by Enterococcus faecalis highly resistant to gentamicin, which failed to respond to conventional antibiotic combination therapy. Extensive in vitro testing was required to determine an appropriate antimicrobial regimen. Despite bacteriological resolution and cardiac surgery the patient died from complications of infective endocarditis.
The pathogenesis of chronic pancreatitis
Authors: Sidhu S S , Tandon R K 
Published: December 2008

Abstract
To date, there is no consensus on the evolution of chronic pancreatitis. Comfort’s initial proposal of acute pancreatitis progressing to chronic pancreatitis was discarded by protagonists of the ‘separate’ theory. Sarles thus stresses the de novo evolution of chronic pancreatitis-acinar protein hypersecretion associated with an imbalance of pancreatic stone promoting and inhibiting factors. However, the ‘necrosis-fibrosis sequence’ hypothesis of Kloppel and Mallet resurrects the probability of acute pancreatitis leading to chronic pancreatitis. Dimagno offers a unifying concept that the degree of acinar injury determines the natural history of pancreatitis. Uninhibited release of toxic free radicals could be a common end point for various aetiologies resulting in acute or chronic pancreatitis. The pathogenesis of chronic calcifying pancreatitis of the tropics is possibly no different from alcoholic chronic pancreatitis. Neurocrine and paracrine mechanisms have been offered to explain pain out of proportion to radiological and histological pancreatic abnormalities in minimal change chronic pancreatitis.
Effect of age upon the induction and maintenance of anticoagulation with warfarin
Authors: Gladman J R F , Dolan G 
Published: December 2008

AbstractWe aimed to examine the effect of age upon the control of anticoagulation with warfarin in ordinary clinical practice, using a retrospective examination of routine anticoagulation clinic records from the University Hospital, Nottingham. Considerable over-anticoagulation (international normalisation ratio (INR) &gt; 6.0) during induction occurred in 54 (11%) of 495 patients and was more likely in older patients (p &lt; 0.05). Lesser degrees of over-anticoagulation during induction (INR &gt; 4.0) were also more common in older patients, occurring in 58% of those aged 75 or above. Loading doses of warfarin were not reduced in older patients. INR in the maintenance phase rose with age (p &lt; 0.001) despite lower maintenance doses of warfarin (p &lt; 0.001). An INR &gt; 6.0 in the maintenance phase was noted in 24 (3%) of 739 patients and again was more likely in older patients (p &lt; 0.05). Patients using ambulance transport to the clinic were older than those who did not (p &lt; 0.01) and those aged over 75 had shorter intervals between clinic visits (p &lt; 0.01). We conclude that doctors using warfarin therapy do not take sufficient account of the increased sensitivity of older people to warfarin. Hospital anticoagulant policies need implementation and evaluation.
Post-thymectomy collapse: an unusual case of acute adrenal insufficiency
Authors: Richardson J 
Published: December 2008

Abstract
A 54-year-old man who had an appearance strongly suggestive of Cushing’s syndrome, collapsed after the removal of a carcinoid tumour of the thymus. The clinical suspicion of acute adrenal insufficiency was supported by invasive haemodynamic data and the diagnosis was subsequently confirmed biochemically. These post-operative events were subsequently ignored and a further crisis was probably prevented by tumour recurrence (and hence resumption of adrenocorticotropic hormone (ACTH) production). The ectopic production of ACTH from a carcinoid tumour of the thymus is recognised but a report of acute adrenal insufficiency from its removal is probably unique.

The first patient had Marfan’s syndrome and hereditary motor and sensory neuropathy Type 1. The second patient had Ehlers-Danlos syndrome, Klippel-Feil syndrome and tomaculous neuropathy.
Prophylactic use of fluconazole in neutropenic cancer patients
Authors: Yamaç K , Șenol E , Haznedar R 
Published: December 2008

Abstract
This study was carried out on 70 patients with haematological or solid malignancies who were receiving chemotherapy and/or radiotherapy. Forty-one patients were randomly assigned to receive fluconazole, 400 mg/day, while they were neutropenic. Systemic fungal infection developed in four of the 41 patients (9%) receiving prophylaxis in comparison to nine of 29 patients (31%) not receiving prophylaxis. The incidence of systemic fungal infection was significantly different between the groups receiving prophylaxis and those not receiving it (p &lt; 0.05). Fluconazole was found to be effective for preventing systemic fungal infections in neutropenic patients with cancer.
Effects of captopril and enalapril on renal function in elderly patients with chronic heart failure
Authors: Haffner C A , Kendall M J , Struthers A D , Bridges A , Stott D J 
Published: December 2008

Abstract
OBJECTIVE: To compare the effects on renal function of captopril and enalapril in elderly patients with chronic heart failure. DESIGN: A multi-centre double-blind parallel-group comparison of the two angiotensin-converting enzyme (ACE) inhibitors, captopril (12.5 mg bid) and enalapril (2.5 mg bid). SUBJECTS: 80 elderly patients with chronic heart failure (41 in the captopril group, 39 in the enalapril group). MAIN OUTCOME MEASURES: The blood pressure and pulse rate response to the first dose of ACE inhibitor was assessed in all patients. Glomerular filtration rate (GFR) was measured radioisotopically by 99mTcDTPA or 51CrEDTA clearance after three and six months of each treatment. Subgroups were assessed for effective renal plasma flow (33 patients), exercise tolerance (25 patients) and by a symptom-oriented questionnaire (45 patients). RESULTS: No serious adverse effect on GFR was noticed. There was no significant difference between the two treatments in the mean baseline GFR or in changes from baseline at three and six months (captopril mean baseline GFR 49.6 ml min-1 1.76 m-2, enalapril 54.7 ml min-1 1.76 m-2; mean change (95% confidence interval) at three months captopril 12 ml min-1 (+3.0, +21.0), enalapril -2 ml min-1 (-13.0; +9.0); mean change at six months, captopril 3.7 ml min-1 (-6.7; +14.2), enalapril -6.0 ml min-1 (-21.0; +9.4). Significantly more patients given captopril had an improvement in GFR during the study period (26/31 compared with 20/31 enalapril-treated patients at three months, p = 0.0096, and 23/30 compared with 15/27 at six months, p = 0.021). There were no significant changes in effective renal plasma flow. Three patients treated with enalapril developed symptomatic hypotension within three days of starting treatment. Quality of life questionnaires revealed more gastrointestinal symptoms in the enalapril group (p = 0.039). CONCLUSIONS: Captopril seems marginally preferable to enalapril in the treatment of chronic heart failure in elderly patients.
Cutaneous scleroderma in association with carcinoid syndrome
Authors: Durward G , Blackford S , Roberts D , Jones M K 
Published: December 2008

Abstract
A case of scleroderma in a woman with carcinoid syndrome is described and the similarities between our case and those in the literature are reviewed. The carcinoid tumours were all of midgut origin and liver metastases were present. All subsequently developed fibrotic heart disease and none had clinical features or autoantibodies suggestive of systemic sclerosis. The association between carcinoid syndrome and particular features of scleroderma is likely to be more than fortuitous.
Fungating carcinoma of the stomach: en bloc multiple organ resection and abdominal wall reconstruction
Authors: Chu K M , Lai D T M , Stern H S , Sheldon D M 
Published: December 2008

Abstract
A patient with carcinoma of the stomach invading multiple adjacent organs and fungating through the anterior abdominal wall was treated by en bloc multiple organ resection and abdominal wall reconstruction. The patient is alive and well at the time of writing, six months after the operation. The rationale for embarking on multiple organ resection for gastric cancer is discussed. However, such an aggressive surgical approach should only be applied to carefully selected patients who are medically fit and have no evidence of widespread systemic metastases.
Antituberculosis treatment-induced hepatotoxicity: role of predictive factors
Authors: Singh J , Arora A , Garg P K , Thakur V S , Pande J N , Tandon R K 
Published: December 2008

AbstractAntituberculosis drug-induced hepatotoxicity is quite common. However, factors predicting its development are still controversial. The objective of the present study was to evaluate the role of certain factors (age and sex of the patient, alcoholism, chronic liver disease, hepatitis B virus carrier status, acetylator status, nutritional status and antituberculosis treatment (ATT) regimen) in predicting the development of ATT-induced hepatitis. In a case-control study, 60 consecutive patients with evidence of ATT-induced hepatitis were studied to assess the possible association of the above-mentioned factors with ATT-induced hepatitis. Body mass index was found to be significantly lower in ATT-induced hepatitis patients (17.2 +/- 2.7) than in controls (19.5 +/- 3.3) (p &lt; 0.05). Pyrazinamide was used in addition to isoniazid and rifampicin in a significantly higher percentage of patients in the ATT-induced hepatitis group (70%) as compared with those in the control group (42%). No significant differences were observed between the two groups with regard to the rest of the parameters.
Drug treatment of toxoplasmic encephalitis in acquired immunodeficiency syndrome
Authors: Winstanley P 
Published: December 2008

Abstract
Toxoplasma gondii is a ubiquitous parasite, which causes several serious diseases. Until the AIDS pandemic, toxoplasmic encephalitis was largely confined to the pharmacologically immune-suppressed and to cases of congenital transmission. T gondii is now one of the more commonly encountered opportunistic pathogens of advanced AIDS.
Central pontine myelinolysis: clinical and MRI correlates
Authors: Martin P J , Young C A 
Published: December 2008

Abstract
Central pontine myelinolysis (CPM) is a rare condition characterised by spastic tetraparesis, pseudobulbar palsy and the ‘locked-in syndrome’. It is frequently fatal. We report a patient who developed CPM secondary to profound hyponatraemia and who recovered with no disability. Serial magnetic resonance imaging (MRI) demonstrated characteristic abnormalities within the pons at the onset of the disease, whereas computerised tomography was normal. Clinical improvement was followed six months later by progressive resolution of the MRI changes, with almost complete resolution after 18 months. Clinical and MRI findings correlate early in the course of CPM but clinical recovery predates MRI improvement by several months.
Stents in the oesophagus
Authors: Murphy G J 
Published: December 2008

Abstract
The use of self-expanding metal stents can markedly improve the care of patients with inoperable oesophageal malignancy. The stents can be easily introduced without the need for general anaesthesia. They have fewer complications during insertion than rigid stents and fewer complications than laser therapy. With these stents lumens of up to 2.5 cm are easily obtainable. The article considers the type of patient who may be suitable for stenting, the technique of insertion, benefits and complications of their use.
Cardioversion of atrial fibrillation
Authors: Lip GYH 
Published: December 2008

Abstract
Cardioversion to sinus rhythm should be considered for all patients in atrial fibrillation in order to improve cardiac performance and perhaps to reduce the long-term risk of thromboembolic complications. Different methods of cardioversion, whether electrical or pharmacological, exist and there is often uncertainty about performing the procedure. In particular, there is often confusion about the use of anti-arrhythmic drugs and the suitable length of anticoagulant therapy required pre- and post-cardioversion. This review discusses the current understanding of electrical and pharmacological cardioversion of atrial fibrillation, the clinical effects and the role of prophylactic anti-arrhythmic and anticoagulant therapy in this procedure.
The quest for a more acceptable bowel preparation: comparison of a polyethylene glycol/electrolyte solution and a mannitol/Picolax mixture for colonoscopy
Authors: Saunders B P , Masaki T , Fukumoto M , Halligan S , Williams C B 
Published: December 2008

Abstract
Eighty-nine consecutive patients attending for day-case colonoscopy were randomly allocated either polyethylene glycol/balanced electrolyte (PEG) mixture (n = 45) or a mannitol/Picolax mixture (n = 44). Both preparations were administered in two fractions. Patients recorded their experience of the preparation on a questionnaire and one of two experienced endoscopists (unaware of the type of preparation given) assessed the result of bowel cleansing. Carbon dioxide insufflation was used for all examinations. Good/excellent bowel cleansing occurred in significantly more patients given PEG, 43 (96%), than those allocated mannitol/Picolax, 34 (77%), p = 0.01. More patients receiving mannitol/Picolax were able to complete the preparation in full than patients receiving PEG (38 vs 27, p = 0.01). More patients found the taste of mannitol/Picolax pleasant compared to PEG (46% vs 20%). Both preparations had a similar side-effect profile. Of those patients tested, 13% receiving mannitol/Picolax had a postural drop in blood pressure and blood parameters suggestive of mild dehydration. A fractionated administration of PEG as a bowel preparation for day-case colonoscopy is well tolerated and superior as a cleansing agent to a mannitol/Picolax combination. Provided carbon dioxide is used as the insufflating agent, mannitol/Picolax is an acceptable alternative in fit, young patients intolerant of PEG.
Liver abscess and disseminated intravascular coagulation in tuberculosis
Authors: Nampoory M R , Halim M M , Sreedharan R , al-Sweih N A , Gupta R K , Constandi J N , Johny K V 
Published: December 2008

Abstract
We report the case of a 55-year-old man with chronic renal failure, and a history of prolonged fever and jaundice. Radiological studies revealed a multiloculated irregular liver abscess. Mycobacterium tuberculosis was isolated from the abscess on smear and culture of aspirated pus. Haematological studies revealed the presence of disseminated intravascular coagulation. A detailed search failed to identify any reason for this other than the tuberculous infection. The treatment of tuberculous liver abscess and pathogenesis of disseminated intravascular coagulation in tuberculosis are discussed.
