Long‐standing ulcerative colitis complicated by right subclavian artery occlusion and upper limbs arteriolitis with digital ischemia

A 48‐year‐old male patient with long‐standing ulcerative colitis since February 2001 which was diagnosed by endoscopy, developed acute digital ischemia affecting both hands with fixed colour changes in the left index finger which was followed shortly by digital ulceration. Magnetic resonance angiography (MRA) of both upper limbs showed evidence of vasculitis affecting digital arterioles on both sided and right subclavian occlusion. The patient received pulse methylprednisolone followed by cyclophosphamide pulse therapy, the latter continuing on a monthly basis for 6 months with appreciable improvement and remission of the vasculitic process; follow‐up MRA showed reperfusion of the previously occluded subcalvian artery. To the authors’ knowledge vasculitis complicating the course of ulcerative colitis is a rare association and is only sporadically reported in the literature. This rare entity should be diagnosed early and aggressively treated; MRA is a very promising diagnostic tool that is suitable for both diagnosis and follow‐up of patients with this rare entity.     

The psychometric properties and correlates of the Reynolds' suicide ideation questionnaire with Kuwaiti and American students.

In samples of Kuwaiti (n=460) and American (n=273) college students, the Reynolds Suicide Ideation Questionnaire (SIQ) proved to have good internal consistency and concurrent validity with measures of anxiety, optimism, pessimism, death obsession, obsession-compulsion, and ego-grasping. The SIQ was factorially complex in both samples, but the eight critical items showed a similar two-factor pattern in both samples. It is important to note that in spite of the great differences between Kuwait and US students and their cultures, the findings were quite similar. By and large, the psychological correlates of the SIQ may have cross-cultural generality.     

Permanent access to the portal system for cellular transplantation using an implantable port device.

A novel application of the implantable Port-a-Cath (PAC) system is described in the context of cellular transplantation. A silicone catheter was inserted in a collateral branch of the portal vein and connected to a port device positioned subcutaneously on the left thoracic cage. This permanent vascular access allowed iterative intraportal infusions of allogenic hepatocytes without the need of repeated transhepatic catheterization of the portal vein. Using this technique, repeated infusions of cryopreserved and / or fresh hepatocytes were successfully carried out in 3 children with inborn errors of liver metabolism, with the aim of progressively providing a sufficient mass of transplanted liver cells to stabilize the metabolic condition of the patients. We suggest that this technique might also be valuable in pancreatic islet cell transplantation.     

A new regimen of amsacrine with high-dose cytarabine is safe and effective therapy for acute leukemia

Amsacrine and high-dose cytarabine (HiDAc), when administered as single agents, are effective treatment of acute leukemia. When used in combination, a high remission rate is also possible. We treated 47 patients with acute myelogenous leukemia (AML), acute lymphoblastic leukemia (ALL), and blastic phase of chronic myelogenous leukemia (CML) with a combination of amsacrine and HiDAc. The patients received amsacrine 200 mg/m2 daily for three days and, concurrently, HiDAc 3 g/m2 over three hours once daily for five days. Of 20 evaluable patients with AML in relapse, there were 12 remissions; of seven additional patients with primary refractory AML, there were two remissions, and of 12 patients with ALL in relapse, there were eight remissions. The three patients with blastic phase CML and the three patients with biphenotypic leukemia did not respond. Nausea, vomiting, stomatitis, hepatic dysfunction, and diarrhea were common, but cutaneous, conjunctival, and significant cerebellar and cerebral side effects were absent. We conclude that this regimen is highly effective therapy for AML and ALL and is also safe, eliminating the major toxicities encountered with HiDAc.
