In recent years there have been significant changes to the diagnosis and management of ectopic pregnancy. In the past ectopic pregnancies were diagnosed and managed surgically in symptomatic women. Since the introduction of Early pregnancy units, the majority of ectopic pregnancies are now diagnosed using transvaginal ultrasound prior to treatment often in asymptomatic women. As a consequence of this, medical and expectant management are accepted alternatives to surgical management in selected cases. This review discusses the various aspects of modern management of ectopic pregnancy. © 2011. Source

An 82-year-old woman, presented with a history of vomiting, abdominal mass and a significantly raised amylase, but no clinical evidence of pancreatitis. Abdominal ultrasound and CT scans showed an ovarian tumour, and no evidence of pancreatitis-as is often associated with a raised amylase. The patient underwent bilateral ovariectomy and hysterectomy and made a good recovery. Source

Background: Many patients with advanced non-small-cell lung cancer (NSCLC) receive only active supportive care because of poor performance status or presence of several comorbidities. We investigated whether erlotinib improves clinical outcome in these patients. Methods: TOPICAL was a double-blind, randomised, placebo-controlled, phase 3 trial, done at 78 centres in the UK. Eligibility criteria were newly diagnosed, pathologically confirmed NSCLC; stage IIIb or IV; chemotherapy naive; no symptomatic brain metastases; deemed unsuitable for chemotherapy because of poor (≥2) Eastern Cooperative Oncology Group performance status or presence of several comorbidities, or both; and estimated life expectancy of at least 8 weeks. Patients were randomly assigned (by phone call, in a 1:1 ratio, stratified by disease stage, performance status, smoking history, and centre, block size 10) to receive oral placebo or erlotinib (150 mg per day) until disease progression or unacceptable toxicity. Investigators, clinicians, and patients were masked to assignment. The primary endpoint was overall survival. Analyses were by intention to treat, and prespecified subgroup analyses included development of a rash due to erlotinib within 28 days of starting treatment. This study is registered, number ISRCTN 77383050. Findings: Between April 14, 2005, and April 1, 2009, we randomly assigned 350 patients to receive erlotinib and 320 to receive placebo. We followed up patients until March 31, 2011. 657 patients died; median overall survival did not differ between groups (erlotinib, 3·7 months, 95% CI 3·2-4·2, vs placebo, 3·6 months, 3·2-3·9; unadjusted hazard ratio [HR] 0·94, 95% CI 0·81-1·10, p=0·46). 59% (178 of 302) of patients assigned erlotinib and who were assessable at 1 month developed first-cycle rash, which was the only independent factor associated with overall survival. Patients with first-cycle rash had better overall survival (HR 0·76, 95% CI 0·63-0·92, p=0·0058), compared with placebo. Compared with placebo, overall survival seemed to be worse in the group that did not develop first-cycle rash (1·30, 1·05-1·61, p=0·017). Grade 3 or 4 diarrhoea was more common with erlotinib than placebo (8% [28 of 334] vs 1% [four of 313], p=0·0001), as was high-grade rash (23% [79 of 334] vs 2% [five of 313], p<0·0001); other adverse events were much the same between groups. Interpretation: Patients with NSCLC who are deemed unsuitable for chemotherapy could be given erlotinib. Patients who develop a first-cycle rash should continue to receive erlotinib, whereas those who do not have a rash after 28 days should discontinue erlotinib, because of the possibility of decreased survival.

Minimally invasive procedures have revolutionised surgery by reducing pain and the length of hospital stay for patients. These are not simple procedures and training in laparoscopic surgery is an arduous process. Meticulous preparation prior to surgery is paramount to prevent complications. We report a rare complication involving a 35-year-old patient who underwent a laparoscopic appendicectomy for a perforated appendix. Two days after surgery the patient experienced redness and swelling in the lower abdominal region and oliguria. A delayed computer tomography (CT) scan revealed contrast leakage around the bladder spreading within the peritoneal cavity consistent with an intraperitoneal bladder perforation. She underwent urinary catheterisation for 6 days. A follow-up CT cystogram showed no evidence of leakage into the peritoneal cavity. This case highlights the need for thorough preparation prior to laparoscopic surgery and careful manipulation of instruments during routine procedures to minimise the risk of serious patient complications such as the aforementioned.

A young man presented with severe hypertension with evidence of both neurological and cardiovascular end-organ damage. Investigation revealed a small right kidney and a left renal artery aneurysm. Significant hypertension persisted even after right nephrectomy. Despite extensive investigation, no evidence was found to implicate the aneurysm in the causation of his high blood pressure. No alternative cause for hypertension was found, yet blood pressure was high even during hospital admission and observed medication dosing with eight antihypertensive agents. Sustained hypertension resulted in worsening left ventricular hypertrophy and he died suddenly at a tragically young age several years after presentation. This gentleman had truly resistant hypertension, a clinical problem which can be very difficult to manage. Source
