Laparoscopic treatment of Meckel's diverticulum

We present two cases in which complication of a Meckel's diverticulum were dealt with, and in one case diagnosed using the laparoscope. One was a large bleeding diverticulum containing ectopic gastric mucosa, with the diagnosis suggested preoperatively, confirmed laparoscopically, and the pathology resected extracorporeally. The second was a partial intermittent small-bowel obstruction due to torsion around the mesodiverticular band, diagnosed and resected via the laparoscope. The literature of Meckel's diverticula and complications is reviewed, with open and laparoscopic treatment options. Although uncommon, many cases of Meckel's diverticulum may be quite suitable for laparoscopic diagnosis and treatment.     

Management of dislocations of both ends of the clavicle

We treated six patients who had a dislocation of both ends of the clavicle (an anterior dislocation of the sternoclavicular joint and a posterior dislocation of the acromioclavicular joint). Two patients who had fewer demands on the shoulder--an elderly woman and a woman who had had an ipsilateral amputation of the hand--did well; they had only minor symptoms after non-operative management. The other four patients (all men) had continuing pain at the acromioclavicular joint; each had a reconstruction of the joint, which resulted in a painless, full range of motion and return to normal activity. No patient had continuing pain in the sternoclavicular joint.     

Acute renal failure without fibrotic skin changes in progressive systemic sclerosis

Scleroderma renal crisis (SRC) is defined as sudden development of accelerated hypertension, hyperreninemia, and acute renal failure in a patient with progressive systemic sclerosis (PSS). Although the diagnosis of PSS is generally straightforward because of dermal fibrosis, we report 2 patients who had PSS with SRC without the characteristic fibrotic skin changes of scleroderma. PSS should be considered in the differential diagnosis of unexplained acute renal failure and accelerated hypertension even though the cutaneous fibrotic manifestations of the disease may be absent.     

Raised corticosterone in the rat after exposure to the elevated plus-maze

Rats given one or two 5-min trials in the elevated plus-maze had plasma corticosterone concentrations significantly higher than the home cage control group and there was no sign of habituation in the group given two trials. In rats given two plus-maze trials the corticosterone responses were significantly higher in the group given 10-min rather than 5-min trials. A previous experience of cat odour (1 week earlier) has no effect on the plasma corticosterone response, but did have an anxiogenic effect that could be detected by a decrease in the percentage of time spent on the open arms of the plus-maze. The results are discussed with reference to the nature of anxiety generated by trials 1 and 2 and by the trial duration in the plus-maze, and with respect to dissociation between behavioural and endocrinological measures.     

Acute respiratory distress during Caesarean section under spinal anaesthesia A probable case of anaphylactoid reaction to Syntocinon

A case of life-threatening respiratory distress during a Caesarean section under spinal anaesthesia is reported. Possible causes of the event including anaphylactoid reactions and the methods of their diagnosis are discussed. The most likely cause of the episode was felt to be an anaphylactoid reaction to Syntocinon.
