Osteochondral Fracture of the Fourth Metatarsal Head Treated by Open Reduction and Internal Fixation

Fracture of the metatarsal head is uncommon, and reports of isolated osteochondral fracture of the metatarsal head are rare. Because of the distal location of the fracture, it is difficult to achieve and maintain reduction, and potential complications include avascular necrosis and subchondral fatigue fracture. The authors present a case of an osteochondral fracture in a 40-year-old man, which was treated by open reduction and internal fixation with a single twist-off screw, with good results 12 months postoperatively.     

Zolpidem induced nocturnal sleep‐related eating disorder (NSRED) in a male patient

Nocturnal Sleep‐Related Eating Disorder (NSRED) is a well‐documented sleeping disorder where the person is reported to experience bizarre eating behavior during sleep. Although various causes are implicated in this disorder, role of drugs cannot be ruled out. Here we narrate an interesting rare case report of a drug‐induced new onset NSRED, where a 45‐year‐old man on zolipdem performed an unexpected and bizarre eating behavior during somnambulistic state, type of which has not been reported earlier in the literature. The case falls under even rarer category as such behavior in sleep is reported mainly in woman. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2009     

A Complication of Stellate Ganglion Block?

Abstract: Stellate ganglion block is commonly used to treat the sympathetically maintained pain which may occur in one‐third of patients with complex regional pain syndrome type 1. A complication that followed a single block and presented a diagnostic dilemma for the ophthalmologist is reported.     

A Worksite Program for Overweight Middle-Aged Men Achieves Lesser Weight Loss With Exercise Than With Dietary Change

Objective To compare changes in total and regional body composition using dual energy X-ray absorptiometry (DEXA) after subjects lost weight through change in diet or exercise.Design A 12-month, randomized, controlled study of two weight-loss interventions — low-fat diet ad libitum or moderate, unsupervised exercise — in free-living, middle-aged men. Compliance was determined at monthly measurement sessions through food records and activity logs; DEXA scans were performed every 3 months.Subjects/setting Fifty-eight overweight men (mean body mass INDEX=29.0±2.6; mean AGE=43.4±5.7 years) recruited from a national corporation were assigned randomly to diet, exercise, or control groups.Interventions One group reduced dietary fat to 26.4% of energy intake but kept activity unchanged; another group self-selected aerobic exercise (three sessions per week at 65% to 75% maximum heart rate) but kept diet unchanged. A control group maintained weight.Main outcome measures At 12 months, measurements of weight, total and regional fat mass and lean mass, energy intake, and percentage dietary fat; physical activity indexes. Statistical analyses Results were analyzed using paired t tests and analysis of variance.Results Mean weight loss was 6.4±3.3 kg in dieters and 2.6+3.0 kg in exercisers; control subjects maintained weight. DEXA scans revealed that 40% of dieters’ weight loss was lean tissue; more than 80% of weight lost by exercisers was fat. Exercisers maintained limb lean tissue and lost fat mass.Conclusions Greater total weight and lean tissue loss occurred when subjects lost weight through a low-fat diet consumed ad libitum than when subjects participated in unsupervised aerobic exercise. Use of DEXA enabled identification of progressive total and regional changes in fat and lean tissue. J Am Diet Assoc. 1997; 97:37–42.     

THE TREATMENT OF ACUTE AND CHRONIC VAGINAL CANDIDOSIS

Vaginal candidosis is one of the most common infections of the vagina and the first accredited record of the disease appeared in 1849. Over the years the terms ‘candidiasis’ and ‘candidosis’ have been used, but it is generally accepted now that the terms are synonymous, and the term most commonly in use today is ‘candidosis’. Mainly caused by the yeast Candida albicans, the condition is characterised by intense inflammation of the vaginal mucosa and a curdy, off-white discharge; it is often associated with severe vulval itching and possibly burning pain. The severity of symptoms seems to vary greatly from patient to patient and the reason for this is unclear. It is suggested that in some patients there may be an element of hypersensitivity. Vaginal candidosis may occur in children but is most common in adults and only sometimes affects the elderly. The majority of women will suffer at least one attack of vaginal candidosis during their lifetime, and there are several predisposing factors such as diabetes, pregnancy and antibiotics. Some authorities consider the condition more frequent in those taking oral contraceptives or other hormones.     

Food deprivation and age modulate neuropeptide gene expression in the murine hypothalamus and adrenal gland.

We have developed a rapid and simple method for quantitative Northern blot analysis of rare messenger RNA species from single mouse hypothalami and adrenals. This technique has allowed us to study the effects of food deprivation on neuropeptide gene expression in the mouse hypothalamus and adrenal gland. The potential modulatory effects of sex and age were also investigated. Food deprivation induced a two-fold increase in the amount of hypothalamic neuropeptide Y (NPY) mRNA, but did not increase NPY mRNA in the brainstem. Age had a significant effect on levels of NPY messenger RNA levels in the hypothalamus. However, there were no gender-associated effects. Sexually immature females (6 weeks old) had higher levels of NPY expression than mature females (9 weeks old). In contrast, in the adrenal gland, increasing maturity was associated with higher levels of NPY mRNA. As in the hypothalamus, fasting caused approximately two-fold increases in NPY mRNA over levels in the ad libitum fed state for both mature and immature mice. Thus, hypothalamic NPY neurons are responsive to nutritional deprivation and developmental status, suggesting that NPY neurons may be important in energy homeostasis.     

Postpemphigus acanthomata: a sign of clinical activity?

Background Pemphigus is a group of vesiculobullous disorders in which the blisters usually heal with hyper- or hypopigmentation. The appearance of acanthomata at sites of previous blisters has been noted in some cases. Methods All cases of pemphigus admitted to the Madras Medical College hospitals during a 2-year period from March 1993 to March 1995 were taken into the study and screened for the presence of acanthomata. Results Fifty-two cases of pemphigus were identified, 47 of pemphigus vulgaris and five of pemphigus foliaceus; and of these 13 developed acanthomata when the blisters healed. Ten of these cases were of pemphigus vulgaris and three were of pemphigus foliaceus; biopsy of these lesions showed hyperkeratosis, acanthosis, papillomatosis, and intraepidermal clefting. Immunofluorescence carried out in two of these acanthomata also showed intercellular fluorescence. Conclusions The occurrence of acanthomata in healed lesions of pemphigus is not uncommon; because histopathologic and immunofluorescence evidence of disease activity is present, cases of this sort require careful follow-up.
