HLH is a frequently lethal disease and with a clinical presentation similar to severe sepsis, MODS, disseminated intravascular coagulation, or septic shock, which are frequent diagnoses in the PICU. In the PICU, HLH should be considered in the case of prolonged fever, splenomegaly, cytopenia, and MODS. It is important for pediatricians and particularly pediatric intensivists to know the diagnostic criteria and possible clinical presentations of HLH so treatment is initiated promptly.

This report evaluates the haemostatic efficacy of recombinant factor VIIa (rFVIIa) and activated prothrombin complex concentrate (APCC) in patients with haemophilia and high responding inhibitors who underwent major and minor surgery. Data pertaining to surgeries from 2001 to 2009 at a single centre were retrospectively analysed. During this period, 53 surgical procedures were performed in 30 haemophiliacs with high responding inhibitors. Mean age was 16.2±9.4 years. Eleven major surgeries in 4 patients, 41 radioisotope synovectomies (RS) and one circumcision classified as minor surgery in 28 patients were performed. Among the major surgery procedures, four were treated with rFVIIa, five with APCC and two with sequential use of APCC and rFVIIa. We used rFVIIa at the dosage of 80-120 μg kg(-1) every 2 h and APCC 100 IU kg(-1) every 12 h for the major surgery. When performing RS, we used rFVIIa in 18 patients with 26 target joints and APCC in 9 patients with 15 target joints. Three consecutive doses of rFVIIa (90 μg kg(-1) ) were used at 2-h intervals followed by additional three doses at 6-h intervals. The initial dose of APCC was 75 IU kg(-1) followed by a second and third dose of 50 IU kg(-1) at 12-h intervals. APCC and rFVIIa demonstrated excellent efficacy in our major and minor surgical interventions [100% (22/22) and 94% (31/33), respectively]. We had only two bleeding complications with rFVIIa. There were no thromboembolic complications. APCC and rFVIIa provide an effective and safe first line haemostatic therapy for inhibitor-positive haemophiliacs, allowing both major and minor surgery to be successfully performed.

Haemophiliacs and their families consider that circumcision is a very important step to become a member of society and it is a social obligation for men in Turkey. Although bleeding risk is high, almost all haemophiliacs would like to be circumcised in Turkish society. The aim of this study was to evaluate our experience in circumcision of haemophilia patients and define efficacy, safety and complication rates of our protocol, called 'Izmir protocol'. In this study, we retrospectively reviewed medical records of 50 patients with haemophilia who underwent circumcision at our hospital according to Izmir protocol between 1996 and 2009. Oral tranexamic acid and fibrin glue were used in all children. One hour before the operation, first dose of factor concentrate was given. After reaching a plasma factor level of around 90-100%, the prepuce was incised circumferentially and excised using Gomco clamp or open technique under general anaesthesia. Intermittent injections of factor concentrate were given every 12 for 48 h. While the first two doses were given at higher amount to achieve or continue plasma factor level at 90-100%, in the last three doses, the aim was to maintain the plasma factor level at 50-60%. Forty-eight hours after the circumcision, patients were discharged. Three patients (6%) showed bleeding complication and all were resolved easily. All had at least one excuse from the protocol (Lower doses of factor concentrates was used in 2, tranexamic acid was not used in 2). Izmir protocol is safe, cheap and easy to carry out.

In conclusion, we found that the clinical effectiveness of bypass therapy in hemophilia cannot be assessed by TGA and TEG.
