Magnetic resonance imaging diagnosis of a cerebral aneurysm in an infant. Case report and review of the literature

A posterior cerebral artery aneurysm presented as a seizure disorder in a 7-week-old infant. A small hemorrhage in the posterior thalamus was seen on CT scan. However, magnetic resonance imaging (MRI study) demonstrated an aneurysm and appropriate therapy was carried out. The incidence, natural history, etiology, and surgical treatment of these lesions are reviewed, and the usefulness of MRI in their diagnosis is emphasized.     

Acute limb ischemia due to malignant arterial embolism from a metastatic germ cell tumor

Arterial tumor embolization is a rare but serious complication of neoplastic disease. The majority of these tumors are associated with primary or secondary lung malignancies, originating from pulmonary vein metastasis or from an atrial mass. Malignant germ cell tumors primarily disseminate to the retroperitoneal lymph nodes and lung, and to the brain and liver later in the course of the disease. A germ cell tumor metastasis embolizing to the iliac-femoral arterial system has not yet been reported. We report a metastatic embolism in a patient with disseminated embryonal cell carcinoma causing acute limb ischemia, managed by surgical embolectomy. The sudden development of limb ischemia in a patient with a germ cell tumor should alert the physician to the possibility of tumor embolism. © 1995 Wiley-Liss, Inc.     

Characteristics of intoxicated trauma patients

Of 1320 patients who were hospitalized for injuries, a total of 315 were known to be intoxicated with alcohol at the time of trauma. A retrospective chart review was performed to determine which biopsychosocial markers correlated with increasing severity of alcohol use disorders in a sample of 184 (58.4%) of these 315 patients. Markers associated with increased severity were: an increased mean corpuscular volume (MCV; p = 0.007), previous legal problems (p = 0.023), previous alcohol rehabilitation (p < 0.001), previous attendance at self-help meetings (p < 0.001), admitting to having an alcohol problem (p < 0.001), and a willingness to change drinking behavior (p < 0.001). Routine toxicology screening tests, simple questions about previous alcohol or drug abuse treatment, and direct questions about the patient's own perception of the severity of disease and readiness to change drinking behavior can identify many victims of major trauma who could potentially benefit from a referral for alcohol rehabilitation.     

Islet transplantation: where do we stand now?

After many years of limited success in islet transplantation, researchers developing this procedure have made great strides, and several centers have now reported that islet transplantation can result in long‐term insulin independence for patients with type 1 diabetes mellitus. The improved quality of life achieved in some islet allograft recipients suggests that this important line of investigation should proceed. Yet, several factors limit the technique and these hurdles must be overcome before it can be considered a practical treatment for the millions of individuals with diabetes, be it type 1 or type 2. Most obvious is the gross disparity between the number of islets available for clinical transplantation and the number of patients with diabetes who might benefit. Other important limitations, too often lost in the discussion, include complications associated with the technique itself, the toxicity of currently available immunosuppressive drugs, and the imperfect glycemia control achieved in most patients. In fact, our ongoing analysis as to whether transplantation‐based therapy improves survival for patients with type 1 diabetes suggests that, for many at least, the opposite may be true. Two variables, as yet undefined, also need to be considered: (1) can the procedure, when done well, prevent or reverse diabetes‐associated complications and (2) what are the long‐term consequences of intrahepatic islets?

Clinical presentation of wandering spleen

Background: Wandering spleen (WS) is an uncommon condition with a variety of clinical presentations. Methods: The medical files of 5 children who underwent operation for WS in the authors' department during the period 1996 through 2000 were retrospectively reviewed. Results: Splenic salvage procedures (retroperitoneal splenopexy) were performed in 4 patients. One patient underwent splenectomy because of splenic necrosis. Conclusions: Early diagnosis and surgical treatment is mandatory to prevent complications. Every effort should be made to preserve the spleen, especially among the pediatric population, and splenopexy is the procedure of choice even in the asymptomatic patient. J Pediatr Surg 37:E30.     

Serum leptin level in women with idiopathic intracranial hypertension

Leptin is a protein secreted by adipose cells which influences regulation of energy balance and body weight. Idiopathic intracranial hypertension (IIH) is recognised as a neurological disorder mainly affecting obese females. The aim of this study was to evaluate the association between IIH and serum leptin level in 15 obese patients and compare the results with those for 16 obese and 15 non-obese women. A significantly higher serum leptin level was found in patients with IIH than in controls (p<0.0001), and this did not correlate with body mass index (BMI). Serum leptin levels were significantly associated with BMI in both control groups (p<0.0006). Additional factors must therefore be involved in the phenomenon of serum leptin increase beyond weight gain. The cause can only be hypothesised, but it seems that the origin is central, probably hypothalamic.     

Intravenous fluids warming by mattress is simple and efficient during pediatric surgery

BACKGROUND/AIM: Temperature control is essential during pediatric surgery. The effectiveness of two methods of warming intravenous (i.v.) fluids to preserve normothermia was compared during abdominal surgery. METHODS: Intraoperative core temperature (CT) was measured in 59 children, 8 years of age and younger. Patients were randomly allocated to two study groups according to the method of fluids warming. In Group M (n = 30), fluids were warmed by placing the i.v. tubing under a warming mattress, and in Group T (n = 29), by using an active i.v. fluid tube warming system. Observations of CT, infusion fluid temperature (IFT) at the entry to the patient and other relevant parameters were made at 30-min intervals throughout the surgical procedure. RESULTS: The two groups did not differ significantly by age, gender, body weight or length of surgical procedure. Although baseline IFT was significantly lower in Group M than in Group T (33.8 degrees C vs. 35.1 degrees C), it increased during the procedure by 1.2 degrees C in Group M compared to a 0.2 degrees C increase in Group T. Baseline CT was also lower by 0.5 degrees C in Group M compared to Group T (NS), but CT increased in Group M by 1.0 degrees C compared to 0.2 degrees C in Group T, resulting in similar final CTs. CONCLUSIONS: The increase in CT was more pronounced in patients where fluids were warmed under the warming mattress (Group M) than in those with fluids warmed by a coil warming device (Group T). The elevation in CT seen in Group M is associated with an increase in infusion fluid temperature at the line just before the i.v. cannula. Both methods of fluid warming (by placing the i.v. tubing under warming mattress and by using a fluid warming system) effectively preserved normothermia during abdominal surgery in children.
