Head and neck cancer patients present with special problems in nutritional homoeostasis because of local phayngeal discomfort and obstruction and difficulty with deglutition due to either the neoplasm or the surgical alterations in the upper aerodigestive tract. Pretreatment malnutrition and vitamin deficiency are only compounded by the nutritional stress imposed by radiation and surgery. Reduced wound complications occur if the patients are nutritionally replenished before treatment. While nasogastric feedings will suffice in many patients, rapid nutritional restoration by this method is limited, and positive nitrogen balance may be difficult to achieve in the severely malnourished patient. Intravenous hyperalimentation offers a rapid and efficacious alternative in selected cases. The case histories of two patients are presented to illustrate these concepts.

BACKGROUND: Comparing primary vertical banded gastroplasty (VBG) and distal gastric bypass (DGBP) patients might assist decision-making based on patient profiles and desired outcomes. METHODS: A prospective study of 81 vertical banded gastroplasty and 60 distal gastric bypass patients. Technical aspects, complications, weight loss, post-op compliance and satisfaction are reported. Length of follow-up is 48 months (VBG) and 36 (DGBP). Lost-to-follow-up 41% (VBG) and 22% (DGBP). Ten per cent of VBGs were revised, with 1% takedown. Three percent DGBPs were converted to proximal GBPs. Demographics are comparable. RESULTS: Operative time was 40 min VBG and 88 DGBP; blood loss 187 cc vs 335 cc; and hospital stay 3 versus 4 days. Exclusive VBG complications include: 1% staple-line leak, 4% intra-abdominal abscess, 1% respiratory failure, 5% pneumonia, 1% intra-abdominal bleed, 1% small bowel obstruction, 2% infected incision, 2% fistula, 2% stenotic or obstructed obstructed stoma, and 1% bezoar. Exclusive DGBP complications include: 2% GI bleed, 12% marginal ulcer, 5% reflux esophagitis, 13% hypocalcemia, 23% hypovitaminosis A and D (12% requiring B12 therapy). Shared complications include hypoproteinemia 6% VBG versus 40% DGBP; excess vomiting (>6 months post-op), 7% versus 10%, excess diarrhea 2% versus 20%, dehydration 1% versus 8%, re-hospitalization 4% versus 15% (hyperalimentation), post-op cholecystectomy 1% versus 5%, weight regain 48% versus 1%. VBG experienced an average of 64% excess weight loss at 36 months versus DGBP 89% excess weight loss. VBG follow-up compliance is generally poor but good for DGBP. Compliance with diet and supplements is equivalent (50%). Satisfaction is 85% and 93% respectively. CONCLUSION: The DGBP provides better long-term weight loss, but nutritional deficiencies occur more often and require close follow-up. The surgery is more complex, but as a primary procedure there are few major complications.

Nutrition and specific nutritional supplements can have prophylactic or therapeutic properties with respect to certain psychiatric disorders. A traditional Mediterranean diet, for example, seems to have prophylactic benefits against depression and dementia, whereas overeating and obesity increase the risk for both.Although evidence for nutritional supplements in the treatment of psychiatric disorders is not sufficient for general recommendations, data from observational studies and randomized controlled trials (RCT) seem to point to their use for specific indications. Folate, S-adenosylmethionine (SAM) and eicosapentaenoic acid (EPA), for instance, seem to have antidepressant properties, zinc may be beneficial in attention deficit hyperactivity disorder (ADHD), vitamin B6 (pyridoxine) could reduce extrapyramidal side effects of antipsychotics and N-acetylcysteine (NAC) seems to be effective against negative symptoms, abnormal movements and akathisia in schizophrenia.Psychiatric disorders, in turn, may lead to deficiency of mineral nutrients and vitamins. For instance, vitamin B1 (thiamine) deficiency is common in alcohol-dependent patients and should therefore be considered during withdrawal treatment. Although vitamin malnutrition is uncommon in developed countries, vitamin deficiency syndromes, such as pernicious anemia or Wernicke's encephalopathy are still relevant differential diagnoses.Some psychopharmacological drugs may additionally change the nutritional habits of the patients in an unfavorable way leading to weight gain and obesity and the risk for further psychiatric problems.
