Restless legs syndrome: diagnosis and review of management options

Restless legs syndrome (RLS) is one of the commonest movement disorders affecting sleep and also daytime functioning. The prevalence may be 8%–10% of the white Caucasian population. The diagnosis is simple and is based on a well-validated clinical questionnaire, yet misdiagnosis is common and the condition remains underdiagnosed and consequently inappropriately treated, often causing great distress to the sufferers. In spite of robust evidence for effective treatment of RLS, patients may often be told to “put up with the symptoms” and suffer the consequence of years of poor sleep which may lead to major lifestyle changes. This review addresses the diagnostic issues, the differential diagnosis, and the evidence base for treatment of the common condition.     

“Dynamic” liver retraction at laparoscopy: An easy and effective technique

Liver retraction is an essential step during any laparoscopic upper gastrointestinal operation, especially during dissection at the oesophageal hiatus. However, the generally employed Nathanson retractor may cause significant postoperative liver dysfunction secondary to congestion of the liver.1,2 It may be technically cumbersome to systematize its frequent use intraoperatively and it may not be readily available at large. Furthermore, the unabated pressure it inflicts on the left lobe of the liver, especially during prolonged surgeries, may lead to hepatic ischaemic necrosis, gangrene, or even unexpected mortality.1 While few recently developed innovative liver retraction techniques seem useful in this context, 2-5 they tend to offer a “static” liver retraction. In this paper, we describe an easy-to-use method of laparoscopic liver retraction wherein any 5mm laparoscopic instrument can be used to manipulate the “heavy” liver so as to provide a “dynamic” counter-traction at will.     

Efficacy of three doses of ketamine with bupivacaine for caudal analgesia in pediatric inguinal herniotomy

BACKGROUND AND OBJECTIVES: Ketamine administered systemically is a potent analgesic at subanesthetic plasma concentrations. Addition of ketamine to bupivacaine for caudal epidural block significantly prolongs the duration of postoperative analgesia. The purpose of this prospective, randomized double-blind study is to identify the optimal dose of ketamine that produces the maximum duration of caudal analgesia with minimal adverse effects as an adjuvant to bupivacaine for caudal epidural block. METHODS: Sixty children, aged 6 months to 10 years, undergoing inguinal herniotomy were allocated randomly to receive 1 of 3 solutions for caudal epidural block. Group 1 received 0.75 mL/kg of bupivacaine 0.25% with preservative-free ketamine 0.25 mg/kg, group 2 received 0.75 mL/kg of bupivacaine 0.25% with ketamine 0.5 mg/kg, and group 3 received 0.75 mL/kg of bupivacaine 0.25% with ketamine 1 mg/kg. Postoperative pain was assessed using the All India Institute of Medical Sciences pain discomfort scale. Rescue analgesia in the form of pethidine 1 mg/kg intramuscularly was administered when this score exceeded 4. RESULTS: The mean duration of caudal analgesia was 8.8 hours in group 1 compared with 22.1 hours in group 2 (P <.001) and 25.2 hours in group 3 (P <.001). Supplemental analgesia requirements with pethidine were significantly less in group 2 (4 subjects) and group 3 (no subject) when compared with group 1 (18 subjects). There were no differences between the groups in the incidence of motor blockade, urinary retention, emesis, or sedation. Group 3 had a significantly higher incidence of behavioral side effects such as odd behavior, agitation, or restlessness than groups 1 and 2. CONCLUSIONS: The optimal dose of ketamine in our study was 0.5 mg/kg added to 0.75 mL/kg bupivacaine 0.25% for caudal epidural block without an increase in side effects.     

Helicobacter pylori eradication: A randomised comparative trial of 7-day versus 14-day triple therapy

Background. Helicobacter pylori is associated with several upper gastrointestinal conditions including chronic gastritis, peptic ulcer disease, and gastric malignancy. Proton pump inhibitor-based triple therapies are considered the standard regimens for H. pylori eradication, but the optimal duration of therapy is controversial. To prevent infection and complications, local studies should be undertaken to evaluate H. pylori eradication rates in a country. Objectives. We compared 7-day and 14-day regimens to determine the optimum duration of triple therapy for H. pylori eradication. Methods. We undertook a prospective randomised comparative trial of 7-day and 14-day triple therapy regimen for H. pylori eradication at the Aga Khan University Hospital, Nairobi; 120 patients with dyspepsia and H. pylori infection were randomised to receive esomeprazole, amoxicillin and clarithromycin for either 7 days (EAC 7) or 14 days (EAC 14). Compliance and side-effects were assessed 2 weeks after the start of therapy and H. pylori eradication was assessed by stool antigen tests 4 weeks after treatment. Results. Both the intention-to-treat (ITT; N=120) and per protocol (PP; N=97) analyses showed no significant differences between the eradication rates of EAC 7 (ITT 76.7%; PP 92%) and EAC 14 (ITT 73.3%; PP 93.6%) (ITT p=0.67; PP p=0.76). Poor compliance was reported in one patient in the EAC 14 group. The incidence of adverse events was comparable in the two groups. Conclusion. One-week and 2-week triple treatments for H. pylori eradication are similar in terms of efficacy, safety and patient compliance.     

Groin pain after a tension-free vaginal tape or similar suburethral sling: management strategies

OBJECTIVE

To review different treatment strategies for women with groin pain after tension‐free vaginal tape (TVT) or similar suburethral sling procedures.

PATIENTS AND METHODS

The series comprised 450 women who had a TVT procedure, with a follow‐up of 3–50 months. Five women (1%) reported significant groin pain and were offered further treatment. In addition, one woman was referred from another centre and received treatment.

RESULTS

Women with pain were initially treated conservatively, and in most the pain resolved and required no further treatment. Persistent or severe discomfort was treated with a combined steroid (methyl prednisolone, 2 mL, 80 mg) and local anaesthetic (bupivacaine, 10 mL, 0.5%) injection in four women. There were no side‐effects from the treatment. One woman was relieved of her pain and required no further treatment. In one woman the local injections failed to improve her symptoms but the pain was not severe enough to warrant further treatment. Two women developed recurrent pain after an initially successful injection, and in these women the TVT was excised. One woman referred from another centre was primarily treated with TVT excision. In the three women treated with distal tape excision, the mean pain scores decreased from 8.7 before excision to 0.7 afterward. One woman is awaiting tape excision.

CONCLUSION

If conservative management fails to relieve the symptoms of groin pain it can be treated by injecting a mixture of steroid and local anaesthetic. However, local injection failed to provide long‐term relief in three of four women. More severe symptoms might require TVT mesh dissection and excision, which provided significant pain relief.

     

National survey of palliative care in end-stage renal disease in the UK.

BACKGROUND: Palliative care for patients with end-stage renal disease (ESRD) is a neglected aspect of nephrology. We carried out this survey to establish the current pattern of provision of palliative care for ESRD in the UK. METHODS: An anonymous but numbered questionnaire concerning local palliative care provision was sent to clinical directors of all 69 UK renal units. RESULTS: All the questionnaires were returned. Only 27 (39%) units employ nursing or Professions Allied to Medicine (PAM) staff with palliative care for ESRD patients as a specified part of their role. In 19 of these units, staff spend <4 h per week concerned with palliative care and only five units have staff working for >12 h a week in this role. Fifty-five (80%) units do not have a written protocol for palliative care. Anaemic ESRD patients with an expected survival of >3 months receive blood transfusion in 59 (86%) units, intravenous iron in 61 (88%) units and erythropoietin in 63 (91%) units. Only 37 (54%) units kept a record of patients seen by the unit staff but deemed not suitable for dialysis. CONCLUSION: There is a significant variation in provision of palliative care services across the UK. In some areas, access to palliative care is restricted to patients with malignant disease, and ESRD patients are excluded.
