Symmetrical interdigital keratoderma of the hands

We report the case of a 26-year-old man affected by a symmetrical keratoderma localized to the interdigital spaces of the fingers. No occupational, traumatic, or irritant factors were discovered. Clinical and histological features were consistent with the diagnosis of symmetrical interdigital hyperkeratosis, a sporadic disorder described by Frei in 1926. We believe this condition to be less rare than the few cases reported in the literature would suggest.

Carcinoid associated encephalitis successfully treated with tryptophan.

This case report describes the rare phenomenon of encephalopathy associated with massive carcinoid tumor. Extensive investigation failed to reveal an obvious cause but a presumptive diagnosis of tryptophan deficiency was made and she was commenced on tryptophan dietary supplements. A rapid and complete response resulted. This case report discusses this unusual case and reviews the literature regarding carcinoid associated encephalopathy.

Laparoscopic Versus Open Renal Procurement for Pediatric Recipients of Living Donor Renal Transplantation

Despite reports demonstrating the safety of laparoscopic donor nephrectomy (LDN) for pediatric recipients of renal transplants, recent evidence has challenged using LDN for recipients 5 years of age or younger. We retrospectively reviewed the records of all pediatric recipients of living donor renal transplants from September 2000 through August 2004. We compared those who received allografts recovered by LDN (n = 34) with those recovered by open donor nephrectomy (ODN, n = 26). Outcomes of interest included operative complications, postoperative renal function, the incidence of delayed graft function or episodes of acute rejection and long-term graft function. Donor and recipient demographic data were similar for the LDN and ODN groups. Serum creatinine and calculated creatinine clearance were not significantly different between groups both in the early postoperative period and at long-term follow-up (p > 0.142). Rates of delayed graft function and acute rejection did not differ between groups. Among recipients aged 5 years old or younger stratified by donor technique (9 LDN, 5 ODN recipients), no difference was noted in graft outcomes both early and long-term (p > 0.079). At our center, pediatric LDN recipients have graft outcomes comparable to those of ODN recipients. At experienced centers, we recommend continued use of LDN for pediatric recipients of all ages.     

Diabetes mellitus-associated diffuse autonomic dysfunction causing debilitating hypotension manifested after rapid weight loss in a morbidly obese patient: case report and review of the literature.

The association between weight and blood pressure is well established, especially the paradigm of obesity-related hypertension. The relationship between diffuse autonomic dysfunction and orthostatic hypotension in patients with long-term diabetes mellitus is also well known. We report on a 57-year-old morbidly obese male with a long medical history of hypertension, myocardial infarction, type 2 diabetes mellitus, and hypothyroidism. After a loss of 147 pounds (representing a percent excess weight loss of 76%) within 6 months after gastric bypass surgery, the patient developed worsening orthostatic hypotension and near-syncopal episodes requiring medication. The subsequent diagnosis and treatment, as well as a literature review, are presented.     

The effect of hypoprolactinemia alone and in combination with cyclosporine on allograft rejection

Recent evidence suggests that prolactin has a role in regulating immune function. Hypophysectomy or administration of bromocriptine results in suppression of the immune response, which is reversed by the administration of prolactin. Hypoprolactinemia has been shown to augment the immunosuppressive effect of cyclosporine. We studied the effect of hypoprolactinemia induced by a new drug, CQP 201-403, on the survival of heterotopic cardiac allografts in the rat and the ability of peripheral blood lymphocytes to respond in vitro to plant mitogens. CQP treatment alone produced a small increase in graft survival but no change in lymphocyte in vitro proliferation (P less than 0.05). CQP treatment greatly enhanced the immunosuppressive effect of cyclosporine on graft rejection and in vitro lymphocyte function (P less than 0.02). We conclude that modulation of prolactin may be a useful adjunct to cyclosporine immunosuppression.     

A preliminary study of serotonergic antidepressants in treatment of dysthymia

Rosenthal, Jesse et al. A Preliminary Study of Serotonergic Antidepressants in the Treatment of Dysthymia. Prog. Neuro-Psychopharmacol. & Biol. Psychiat. 1992, 16(6): 933–941.

1. 1. There is increasing evidence that antidepressants may alleviate symptoms of dysthymia, but few prior studies on selective serotonergic agents.

2. 2. Twenty patients meeting criteria for dysthymia, but not meeting criteria for major depression, received open label trials of a serotonergic antidepressant, either fluoxetine or trazodone.

3. 3. Seventeen (85%) completed three-month medication trials, and of these, twelve (70.6% of completers) responded to treatment. Seven (41.2% of completers) were still in remission on followup at five months.

4. 4. Both fluoxetine and trazodone were well tolerated in dysthymics, and showed similar short-term effectiveness in treating dysthymic symptoms.

Does routine stress-thallium cardiac scanning reduce postoperative cardiac complications?

OBJECTIVE: Prophylactic cardiac revascularization in patients with ischemic myocardium could reduce postoperative cardiac complications after aortic reconstruction. However, the effectiveness of this approach has not been documented. SUMMARY BACKGROUND DATA: Stress-thallium scanning can identify patients with ischemic myocardium. Morbidity and mortality after aortic reconstruction appears to be largely caused by co-existent coronary artery disease, and patients who have had recent cardiac revascularization have few postoperative cardiac complications. METHODS: Preoperative stress-thallium scanning was evaluated prospectively in 146 patients undergoing aortic reconstruction. Patients with positive studies underwent coronary arteriography and cardiac revascularization, when appropriate. Postoperative cardiac complications and long-term survival in these patients were compared with results from 172 similar patients undergoing aortic reconstruction without stress-thallium scanning. Results also were analyzed to determine predictors of postoperative cardiac events. RESULTS: Forty-one per cent of patients undergoing stress-thallium testing underwent coronary arteriography, and 11.6% had cardiac revascularization. In contrast, 14.7% of patients treated without stress-thallium testing had coronary arteriography, and 4.1% had revascularization (p < 0.01). Despite this, cardiac mortality, serious cardiac complications, and long-term cardiac mortality were similar in both groups. Only advanced age and intraoperative complications (but not a positive stress-thallium test) predicted postoperative cardiac events. CONCLUSIONS: Preoperative stress-thallium testing confirmed a high incidence of significant coronary artery disease in patients undergoing aortic reconstruction, but prophylactic cardiac intervention does not reduce operative or long-term mortality. Thus, the risk and expense of routine stress-thallium testing and subsequent cardiac revascularization cannot be justified.
