Hypomagnesaemia in postoperative patients: an important contributing factor in postoperative mortality.

Magnesium is the second most abundant intracellular cation and the fourth most abundant cation in the body. Clinical manifestations of hypomagnesaemia include neuromusclar, neurological, psychiatric and cardiac arrhythmias including torsade de pointes resulting in sudden death. Incidence of hypomagnesaemia in hospitalised patients in common and there is a lack of clinical awareness. Clinicians should become familiar with the common conditions and therapeutics that are risk factors for underlying hypomagnesaemia and become familiar with magnesium replacement regimens. Two patients who suffered fatal complications in whom hypomagnesaemia was an important contributing factor are presented. Hypokalaemia and hypocalcaemia are common in severe magnesium deficiency and require concurrent monitoring and correcting.

Case report: amoebic liver abscess complicated by a hepatoduodenal fistula.

Amoebic liver abscess (ALA) is a common extra-intestinal presentation of amoebiasis caused by Entamoeba histolytica. The liver abscess may be complicated by rupture into adjacent structures. Common organs involved include thorax, peritoneum and pericardium. Rupture into the gastrointestinal tract is extremely rare. We report a patient who developed a hepatoduodenal fistula complicating an amoebic liver abscess. Suspicions were raised on finding air in the liver abscess on ultrasound scanning. Diagnosis was confirmed on a water-soluble (Gastrografin) swallow (Fig. 1 a,b). Complications of ALA are associated with a high morbidity and mortality and early diagnosis is important. To our knowledge only one previous case of a hepatoduodenal fistula complicating an ALA with radiological confirmation has been reported.
