Safety and efficacy of long-term low-dose clozapine aftercare treatment in a patient with learning difficulties who suffered from neuroleptic malignant syndrome

INTRODUCTION : Antipsychotic medication continues to be an essential component in the treatment of schizophrenia. Neuroleptic malignant syndrome (NMS) is one of the most serious complications of neuroleptic treatment and the optimal therapeutic aftercare regimen for patients is unclear. Also, it is not clear if low-dose neuroleptic maintenance in such patients is safe and efficient enough over time. METHOD : We present a case of a 56-year-old woman suffering from schizoaffective disorder, who was successfully treated with a low dosage of clozapine for 6.5 years following a NMS episode. RESULT : To the best of our knowledge this is the first report of such a long-term beneficial use of low-dose clozapine in a patient who previously underwent such a serious complication. CONCLUSION : Large-scale studies are needed to substantiate this observation. (Int J Psych Clin Pract 2002; 6: 121-123)     

Pituitary-directed medical therapy with pasireotide for a corticotroph macroadenoma: pituitary volume reduction and literature review

Hypercortisolism due to an ACTH-secreting pituitary adenoma (Cushing’s disease) is a chronic condition associated with high morbidity and mortality if inadequately managed. Pasireotide is a multireceptor-targeted somatostatin analogue and is the only approved medical therapy for Cushing’s disease that treats the underlying cause of the disorder. This paper reviews the available literature for medical-therapy-induced adenoma volume reduction in patients with Cushing’s disease and reports the experience of a 53-year-old surgically, radiologically and medically naïve (de novo) female with a pituitary macroadenoma who declined surgery. This patient was treated with pasireotide as first-line therapy as part of the largest randomized Phase III study evaluating a medical therapy in patients with Cushing’s disease (SOM230B2305 trial). Subcutaneous pasireotide significantly decreased tumor volume, suppressed cortisol secretion, and improved clinical signs and symptoms of Cushing’s disease in this patient. Based on this experience, first-line pasireotide has the potential to achieve substantial tumor volume reduction in addition to significant improvements in cortisol levels and signs and symptoms in patients with Cushing’s disease for whom surgery is not an option.     

Food Allergy: Temporal Trends and Determinants

This review summarizes studies discussing temporal trends in the prevalence of food allergy as well as potential factors associated with the development of food allergy. In addition, we will address the potential hypotheses accounting for the apparent increase in food allergy prevalence. Studies suggest increased prevalence of food allergy. However, relatively little is known about its pathogenesis. This review aims to assess temporal trends in the prevalence of food allergy and discuss potential genetic, environmental, and demographic determinants. The search strategy examined the medical literature database MEDLINE (using PubMed) for the time period of January 1, 2002 to January 31, 2012. In recent decades, the prevalence of food allergy in general has increased by 0.60 % [95 % confidence interval (CI), 0.59 %-0.61 %] and the prevalence of peanut allergy by 0.027 % (95 % CI, 0.026 %-0.028 %), but it has now likely stabilized in developed countries. Genes, the environment, and demographic characteristics play a role in the pathogenesis of food allergy. Numerous environmental and demographic factors as well as gene-environment interactions may account for this increase in prevalence, but further studies are required to tease out their relative contribution.     

Postoperative Swallow Study as a Predictor of Intermediate Weight Loss after Sleeve Gastrectomy

Background

Laparoscopic sleeve gastrectomy (LSG) is an accepted bariatric procedure. Swallow studies (SS) after LSG are not uniform and display different patterns with regard to contrast passage through the gastric sleeve. The impact of immediate postoperative contrast transit time on weight loss has not been studied. The influence of immediate fluid tolerance on weight loss after LSG is herein reported.

Methods

Ninety-nine patients after LSG were included. There were 67 females, mean age 41 (range 17–67), mean BMI 44.4 (range 37–75). A routine SS was performed on postoperative day (POD) 1. Pattern of contrast transit was noted. Patients were followed-up in our bariatric clinic.

Results

Percent excess weight loss was significantly lower in the patients with rapid contrast passage (Group 1, n?=?50) than those with delayed passage (Group 2, n?=?49). Group 1 achieved 62, 58, and 53 % at 1, 2, and 3 years, respectively, while Group 2 attained 69, 74, and 75 % at the same time points (p?=?0.05, 0.001, and 0.04, respectively). Group 1 patients displayed a negative weight loss trend after 1 year whereas Group 2 patients plateaued after 2 years.

Conclusions

Tolerance of fluid intake after LSG is crucial for patient recovery and discharge. Distinct radiologic appearance on POD 1 helps predict this behavior. Mid-term weight loss after LSG appears to be dependent on immediate postoperative contrast transit time, whereas patients with slow contrast passage tend to lose more weight. Long-term follow-up will reveal whether this finding will hold true.     

Midodrine-Induced Vascular Ischemia in a Hemodialysis Patient: A Case Report and Literature Review

Midodrine is an alpha-agonist that causes peripheral vasoconstriction, resulting in increased blood pressure. It has been reported to be safe and effective in patients with end stage renal disease (ESRD) and is widely used for hemodialysis-associated hypotension. We report a case report of midodrine-induced ischemia in a patient on hemodialysis and review the literature relating to the safety of midodrine in patients with end stage renal disease.     

Increased median nerve latency at the carpal tunnel of patients with "trigger finger": Comparison of 62 patients and 13 controls

An association between symptomatic compression neuropathy of the median nerve at the carpal tunnel and "trigger finger" has been reported in endocrine and metabolic disorders. We assessed the incidence of increased median nerve latency in subjects with "trigger finger". 62 consecutive patients with "trigger finger" and no signs or symptoms of median nerve compression underwent nerve conduction studies of the median nerve. 13 healthy adults served as controls. 39/62 patients had increased distal motor latency in the median nerve. Only 1 of 13 subjects in the control group had a borderline value of distal motor latency.
