Age affects the human taste system at peripheral and central levels. Metabolic syndrome is a constellation of risk factors (e.g. Read More

, abdominal obesity and hypertension) that co-occur, increase with age, and heighten risk for cardiovascular disease, diabetes, and cognitive decline. Little is known about how age, metabolic syndrome, and hunger state interact to influence how the brain processes information about taste. We investigated brain activation during the hedonic evaluation of a pleasant, nutritive stimulus (sucrose) within regions critical for taste, homeostatic energy regulation, and reward, as a function of the interactions among age, metabolic syndrome, and hunger condition. We scanned young and elderly adults, half with risk factors associated with metabolic syndrome twice: Once fasted overnight and once after a preload. Functional magnetic resonance imaging data indicated significant effects of age as well as interactive effects with metabolic syndrome and hunger condition. Age-related differences in activation were dependent on the hunger state in regions critical for homoeostatic energy regulation and basic as well as higher order sensory processing and integration. The effects of age and metabolic syndrome on activation in the insula, orbital frontal cortex, caudate, and the hypothalamus may have particularly important implications for taste processing, energy regulation, and dietary choices.

Sweet syndrome (SS) is an uncommon dermatologic disorder that could be associated with hematologic malignancies.
To describe the clinicopathologic, immunophenotyping and cytogenetic characteristics of SS in Egyptian patients with acute myeloid leukemia (AML).
The study was conducted during the period from April 2011 to March 2015. Read More

For each patient, a clinical evaluation and histological assessment of cutaneous lesions were recorded. Diagnostic investigations, immunophenotyping and cytogenetic features of leukemia were analyzed. Therapeutic monitoring and follow up of both diseases were registered.
The study included 13 patients (7 males and 6 females) with a mean age of 44.4±17.49years. Fever was recorded in 10 cases and most of the lesions (61.5%) appeared during the post remission period. Clinically, the lesions were more frequently located on the extremities (61.5%), presented as solitary lesion (53.8%) and mostly tender (69.2%). Atypical presentations were observed in 5 cases and included ulcerative lesion, indurated mass and a gangrenous mass. Histological assessment revealed two patterns of inflammatory reactions described as classic (dermal) form (38.5%) and deep (subcutaneous) form (61.5%). Laboratory investigations showed leukocytosis in 61.5%, neutropenia in 38.5%, anaemia in 92.3%, and thrombocytopenia in 84.6%. Bone marrow aspiration and biopsy showed suppressed trilineage hematopoesis in 84.6% and blast cell count >50% in 69.2%. The common subtypes of AML included M2 and M4 (23.1% for each). Cytogenetic studies revealed genetic abnormalities in 69.2% of cases. Most of the cases (76.9%) showed a poor response to oral prednisolone but responded well to alternative therapies, including dapsone, colchicine and cyclosporine.
Sweet syndrome associated with AML may show atypical clinical forms that have an aggressive course and is mostly associated with subcutaneous involvement. Although chemotherapy of AML may play a significant role in the development of SS, the exact mechanism remains unclear. The disease is considered a steroid refractory and genetic abnormalities may have a role in altering the classic nature of the disease.

Sweet syndrome is a rare disorder that is manifested by constellation of clinical features, including fever, neutrophilic leucocytosis, raised painful plaques on skin and dermal infiltration by neutrophils. Numerous aetiological associations have been reported in the literature, including various haematological malignancies and drugs. Our case was peculiar because of association of capecitabine and Sweet syndrome in rectal cancer. Read More

We describe a case of a woman aged 57 years, with recently diagnosed stage III rectal cancer, developed painful erythematous rash over her face along with fever and headache. Skin biopsy was performed which revealed typical findings of Sweet syndrome. She was successfully treated with systemic steroids. Our case was an unusual presentation of Sweet syndrome in a patient with rectal adenocarcinoma treated with neoadjuvant capecitabine.

Acute rejection (AR) and development of chronic rejection, bronchiolitis obliterans syndrome (BOS), remain major limiting factors for lung transplantation (LTx). This retrospective study is to identify differentially expressed circulating microRNAs (miRNAs) that associate with development of AR and BOS in pediatric lung transplant recipients (LTxR).
We determined the circulating levels of 7 selected candidate miRNAs in 14 LTxR with AR, 7 with BOS, and compared them against 13 stable pediatric LTxR at 1, 6, and 12 months following LTx. Read More

In addition, 6 AR, 7 BOS and 8 stable pediatric LTxR, 16 AR, 17 BOS and 16 stable adult LTxR were included for validation.
MiR-10a, -195, -133b were significantly lower in AR and miR-144, -142-5p, -155 were higher in AR compared to stable (p<0.05). In addition, circulating levels of miR-134, -10a, -195, -133b were significantly lower and miR-144, -142-5p, -155 were higher (p<0.05) with development of BOS. The receiver-operating characteristic demonstrated that miR-142-5p, miR-155, and miR-195 strongly discriminated patients with AR from stable LTxR (p<0.001 for all comparisons): miR-142-5p (area under the curve (AUC=0.854), miR-155 (AUC=0.876), and miR-195 (AUC=0.872). Further, miR-10a, miR-142-5p, miR-144, and miR-155 strongly discriminated BOS from stable LTxR (p<0.001 for all comparisons).
We demonstrated that differential expression of circulating miRNAs occurs in LTxR with AR and BOS, suggesting that they can provide not only important clues to pathogenesis but also may serve as potential noninvasive biomarkers for AR and BOS following pediatric LTx.

Neutrophilic dermatosis of the hand (NDH) is a rare localized variant of the syndrome, originally described two decades ago by Strutton et al. The lesions of NDH and Sweet syndrome are similar, as indicated in the first report of NDH. Both diagnoses are characterized by an acute onset of fever, leukocytosis, and tender, erythematous infiltrated plaques. Read More

There are also bullae and ulceration in NDH, in contrast to Sweet syndrome, in which bullae are quite uncommon, especially at the early stages. Similar to Sweet syndrome, the majority of NDH patients are women (69%). Patients with NDH present with fever, peripheral neutrophilia, leukocytosis, and/or an elevated erythrocyte sedimentation rate or C-reactive protein level, but at a significantly lower rate than those in Sweet syndrome (33%). Similar to Sweet syndrome, NDH has been associated with the following conditions: Malignancies (particularly hematological [21%], most common of which is acute myelogenous leukemia, but many other malignancies as well), inflammatory bowel disease (19%), medication and vaccination-related eruptions, bacterial and viral infections, rheumatologic diseases, and others. The clues to the diagnosis of NDH are the same as for Sweet syndrome. Awareness of this diagnosis is important not only to avoid unnecessary medical and surgical therapy and to expediently initiate the administration of steroids for this highly responsive dermatosis, but also to conduct an appropriate workup to exclude associated diseases, especially malignancies.

Multiple chemical sensitivity (MCS) is a disorder characterized by nonspecific and recurrent symptoms from various organ systems associated with exposure to low levels of chemicals. Patients with MCS process odors differently than controls do. Previously, we suggested that this odor processing was associated with increased regional cerebral blood flow (rCBF) in the prefrontal area during olfactory stimulation using near-infrared spectroscopic (NIRS) imaging. Read More

The aim of this study was to investigate the association of odor thresholds and changes in rCBF during olfactory stimulation at odor threshold levels in patients with MCS. We investigated changes in the prefrontal area using NIRS imaging and a T&T olfactometer during olfactory stimulation with two different odorants (sweet and fecal) at three concentrations (zero, odor recognition threshold, and normal perceived odor level) in 10 patients with MCS and six controls. The T&T olfactometer threshold test and subjective assessment of irritating and hedonic odors were also performed. The results indicated that the scores for both unpleasant and pungent odors were significantly higher for those for sweet odors at the normal perceived level in patients with MCS than in controls. The brain responses at the recognition threshold (fecal odor) and normal perceived levels (sweet and fecal odors) were stronger in patients with MCS than in controls. However, significant differences in the odor detection and recognition thresholds and odor intensity score between the two groups were not observed. These brain responses may involve cognitive and memory processing systems during past exposure to chemicals. Further research regarding the cognitive features of sensory perception and memory due to past exposure to chemicals and their associations with MCS symptoms is needed.
