Background: Two commonly performed surgical interventions are available for severe (grade II-IV) haemorrhoids; traditional excisional surgery and stapled haemorrhoidopexy. Uncertainty exists as to which is most effective. The eTHoS trial was designed to establish the clinical effectiveness and cost-effectiveness of stapled haemorrhoidopexy compared with traditional excisional surgery., Methods: The eTHoS trial was a large, open-label, multicentre, parallel-group, pragmatic randomised controlled trial done in adult participants (aged 18 years or older) referred to hospital for surgical treatment for grade II-IV haemorrhoids. Participants were randomly assigned (1:1) to receive either traditional excisional surgery or stapled haemorrhoidopexy. Randomisation was minimised according to baseline EuroQol 5 dimensions 3 level score (EQ-5D-3L), haemorrhoid grade, sex, and centre with an automated system to stapled haemorrhoidopexy or traditional excisional surgery. The primary outcome was area under the quality of life curve (AUC) measured with the EQ-5D-3L descriptive system over 24 months, assessed according to the randomised groups. The primary outcome measure was analysed using linear regression with adjustment for the minimisation variables. This trial is registered with the ISRCTN registry, number ISRCTN80061723., Findings: Between Jan 13, 2011, and Aug 1, 2014, 777 patients were randomised (389 to receive stapled haemorrhoidopexy and 388 to receive traditional excisional surgery). Stapled haemorrhoidopexy was less painful than traditional excisional surgery in the short term and surgical complication rates were similar between groups. The EQ-5D-3L AUC score was higher in the traditional excisional surgery group than the stapled haemorrhoidopexy group over 24 months; mean difference -0·073 (95% CI -0·140 to -0·006; p=0·0342). EQ-5D-3L was higher for stapled haemorrhoidopexy in the first 6 weeks after surgery, the traditional excisional surgery group had significantly better quality of life scores than the stapled haemorrhoidopexy group. 24 (7%) of 338 participants who received stapled haemorrhoidopexy and 33 (9%) of 352 participants who received traditional excisional surgery had serious adverse events., Interpretation: As part of a tailored management plan for haemorrhoids, traditional excisional surgery should be considered over stapled haemorrhoidopexy as the surgical treatment of choice., Funding: National Institute for Health Research Health Technology Assessment programme., (Copyright © 2016 The Author(s).

Background: Infertility is a common late effect of chemotherapy and radiotherapy, and has a substantial effect on the quality of life for young survivors of cancer. For men, semen cryopreservation is a simple way of preserving reproductive potential but for women, storage of mature eggs rarely proves successful, and the alternative-immediate in vitro fertilisation with cryopreservation of embryos-is not always appropriate. Reimplantation of cryopreserved ovarian tissue has been shown to restore natural fertility in animals. We applied this technique in a woman who had received sterilising chemotherapy for lymphoma., Methods: A 36-year-old woman underwent a right oophorectomy with cryopreservation of ovarian cortical strips before receiving high-dose CBV chemotherapy for a third recurrence of Hodgkin's lymphoma. 19 months later, when serum sex steroid analysis confimed a postmenopausal state, two ovarian cortical strips were thawed and reimplanted-one onto the left ovary and another at the site of the right ovary., Findings: 7 months after reimplantation of ovarian cortical strips, the patient reported resolution of hot flashes and, for the first time, oestradiol was detected in the serum. This finding was associated with a decrease in the concentrations of follicle-stimulating hormone and luteinising hormone, and ultrasonography revealed a 10 mm thick endometrium, a poorly visualised left ovary, and a 2 cm diameter follicular structure to the right of the midline. The patient had one menstrual period, but by 9 months after the implantation, her sex steroid concentrations had returned to those seen with ovarian failure., Interpretation: Orthotopic reimplantation of frozen/thawed ovarian cortical strips is a well tolerated technique for restoring ovarian function in women treated with sterilising chemotherapy for cancer.

54 patients have been studied after paracetamol (acetaminophen) overdose. Liver-function tests and fasting serum bile-acids were measured daily; liver biopsy was done in all cases, and slides were examined "blind" to assess liver damage. The plasma-paracetamol was measured on one occasion. A histological abnormality was present in the livers of 53 of the 54 patients, and was minor in 23, moderate in 16, and severe in 14. In 6 patients with moderate and 18 with mild histological abnormality liver-function tests were normal. A serum-aspartate-aminotransferase above 400 units/1 was always associated with severe histological liver damage. Fasting serum bile-acids were raised in 51 of the patients with abnormal liver histology; the serum-bile-acid seemed to be a more sensitive indicator of mild liver-cell damage than was the transaminase level. There was, however, little correlation between increase in bile-acid concentration and the degree of histological abnormality. As a result of these investigations empirically determined levels of plasma-paracetamol have been drawn which give a guide to the likelihood of liver damage after paracetamol overdose.

Transient severe hyperammonaemia developed in the absence of serious liver dysfunction in three patients being treated for acute leukaemia. The onset of the biochemical disturbance was abrupt and led rapidly to acute encephalopathy, fatal in two cases. In the third patient, prompt initiation of aggressive haemodialysis and intravenous sodium benzoate and sodium phenylacetate infusion successfully controlled plasma ammonium levels until they spontaneously resolved. The cause of the disorder remains to be determined, but urinary nitrogen partition studies suggest temporary impairment of ureagenesis in a catabolic setting as a major pathophysiological feature of this disorder. The absence of liver disease, the normal mitochondrial ultrastructure seen in two cases, and the plasma aminoacid profiles observed serve to distinguish this disorder from others such as Reye's syndrome.

The presentation or method of detection of 93 patients with primary biliary cirrhosis (PBC) from Northern England is reported. Almost half (45/93) the patients had no symptoms of liver disease when PBC was diagnosed; in many of them serum antimitochondrial activity (AMA) was detected during immunological screening for other diseases. 13 patients with normal liver function tests had symptomless PBC. Liver histology in 6 of these was diagnostic for PBC, and 7 had histology suggestive of PBC; all had a positive AMA titre greater than or equal to 1/40. The mortality of the symptom-free AMA-positive patients over a mean follow-up of 4-5 years did not differ from that of the general population. Only 1 out of 45 initially symptom-free patients died in the follow-up period (8 months-12 years). 37 patients had disorders which may be associated with PBC--including 16 with thyroid disease, 9 with rheumatoid arthritis, and 5 with mixed connective tissue disease. It is suggest that, as with autoimmune thyroid disease, overt organ damage never develops in many patients with symptomless PBC.

Retrospective analysis of the records of 31 patients diagnosed as having Giardia lamblia infection in our hospital over a five-year period suggests that the condition is not considered often or early enough. Adult patients particularly "suffer" more, having to endure more investigations (mean of 16) than do symptomatic children (mean of 6) before a diagnosis is made. The length of time to reach the diagnosis from first referral further supports this view, being almost seven weeks in adults and three weeks in children--both groups having had symptoms for an average of seven months before referral.
