Care for the organ transplant recipient on the intensive care unit.

All transplant recipients receive tacrolimus, mycophenolate and glucocorticoids and these drugs have many side-effects and drug-drug interactions. Common complications include surgical complications, infections, rejection and acute kidney injury. Infections as CMV and PJP can be prevented with prophylactic treatment. Given the complexity of organ transplant recipients a multi-disciplinary team of intensivists, surgeons, pharmacists and transplant specialists is essential. After heart transplantation a temporary pacemaker is required until the conduction system recovers. Stiffening of the heart and increased cardiac markers indicate rejection. An endomyocardial biopsy is performed via the right jugular vein, necessitating its preservation. For lung transplant patients, early intervention for aspiration is warranted to prevent chronic rejection. Risk of any infection is high, requiring active surveillance and intensive treatment, mainly of fungal infections. The liver is immunotolerant requiring lower immunosuppression. Transplantation surgery is often accompanied by massive blood loss and coagulopathy. Other complications include portal vein or hepatic artery thrombosis and biliary leakage or stenosis. Kidney transplant recipients have a high risk of cardiovascular disease and posttransplant anemia should be treated liberally. After postmortal transplantation, delayed graft function is common and dialysis is continued. Ureteral anastomosis complications can be diagnosed with ultrasound.

Severe group A streptococcal toxic shock syndrome presenting as primary peritonitis: a case report and brief review of the literature.

Streptococcal toxic shock syndrome (STSS) can be defined as a septic shock syndrome resulting from infection with toxin-producing group A streptococci (GAS). STSS can sporadically present as primary peritonitis in previously healthy persons. Signs of STSS are non-specific and patients generally present with flu-like symptoms and can develop a life-threatening toxic shock syndrome in just a few hours. Diagnosis is mainly by a combination of physical examination, laboratory/culture results, and exclusion of surgical causes by means of imaging modalities and/or surgical exploration. GAS remain penicillin-sensitive and most are clindamycin-sensitive. Prompt supportive treatment, possibly together with high-dose intravenous immunoglobulins, is crucial.

Sporadic porphyria cutanea tarda due to haemochromatosis.

Haemochromatosis is a hereditary iron-overload syndrome caused by increased intestinal iron absorption and characterised by accumulation of potentially toxic iron in the tissues. Sometimes this disease presents as a cutanea porphyria. We describe a patient with joint complaints and blistering skin lesions on sun-exposed skin. After identifying the porphyria cutanea tarda by urine analysis we found that the serum activity of uroporphyrinogen decarboxylase (UROD) was normal, meaning a partial inactivation of UROD in liver tissue due to external factors. Further investigation showed the homozygous Cys282Tyr missense mutation and high levels of serum ferritin. It is important to recognise the symptoms of iron overloading at an early stage because hereditary haemochromatosis needs to be treated immediately. We therefore advocate routine sampling of ferritin levels in patients with unexplained joint complaints.

[Abnormalities in tattooed skin: sometimes sarcoidosis]. / Afwijkingen in getatoeëerde huid: soms sarcoïdose.

A 43-year-old man presented with a nodular tattoo lesion on his right upperarm. Histologically it resembled the granulomatous reaction seen in systemic sarcoidosis. Further evaluation revealed asymmetrical hilar lymphadenopathy with no interstitial lung disease. Since the patient was a heavy smoker, bronchus carcinoma could not be excluded and cervical mediastinoscopy was performed in order to obtain a lymph-node biopsy. This confirmed the diagnosis of systemic sarcoidosis. The patient was treated by local application of corticosteroids, but with little result. Skin lesions in scars or tattoos may be the first symptom of systemic sarcoidosis. Skin biopsy for histological confirmation of the diagnosis is recommended, as is further investigation to evaluate other organ systems which may be affected.
