Fifteen bronchial asthma patients were followed-up for 6 months. They were administered beclomet-250 in a daily dose 1000 micrograms. The patients' clinical status was characterized by positive changes, ventilation function of the lungs improved. The drug was discovered to produce no suppressive action on adrenal function. Besides, the patients did not develop oropharyngeal candidiasis.  相似文献

Thrombosis of a giant aneurysm after extracranial-intracranial bypass.   总被引:2,自引:0,他引:2  
A patient presenting with a giant, fusiform middle cerebral artery aneurysm underwent extracranial to intracranial bypass grafting before permanent occlusion of the aneurysm. The patient was to return 4 months later for endovascular treatment. Arteriography obtained before obliteration revealed complete aneurysmal thrombosis. No further treatment was deemed necessary. Factors predisposing to thrombosis are discussed.  相似文献

Summary. 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.  相似文献

BACKGROUND: Narrow band ultraviolet B (NB-UVB) phototherapy has been used successfully for the treatment of vitiligo. Recently, topical calcipotriol has also been claimed to be effective, either as monotherapy or as a part of combination therapies. OBJECTIVE: The aim of the present study was to compare the clinical efficacy of NB-UVB and NB-UVB plus topical calcipotriol in the treatment of vitiligo. METHODS: NB-UVB treatment was given to 24 patients with generalized vitiligo three times weekly. Topical calcipotriol cream was only applied to the lesions located on the right side of the body. Treatment was continued for 6 months. Treatment efficacy was evaluated by determining the average response rates of the lesions at 3-month intervals. RESULTS: The average response rates of patients receiving combination of NB-UVB plus calcipotriol and NB-UVB alone were 51 +/- 19.6% and 39 +/- 18.9%, respectively. The median cumulative UVB dose and number of UVB exposures for initial repigmentation were 6345 mj/cm(2) (range; 2930-30980) and 18 (range; 12-67) for the combination therapy, and 8867.5 mj/cm(2) (range; 2500-30980) and 24 (range; 15-67) for the narrow band UVB therapy, respectively. CONCLUSIONS: These findings indicate that concurrent topical calcipotriol potentates the efficacy of NB-UVB in the treatment of vitiligo. This combination not only provides earlier pigmentation with lower total UVB dosage and less adverse UVB effects, but also reduces the duration and cost of treatment as well.  相似文献
