The long term effect of sulfur mustard (SM) exposure including, total and differential white blood cells (WBC), hematological parameters, pulmonary function tests (PFT), and respiratory symptoms (RS) in chemical war victims (CWV) exposed to SM 27-30 years ago were examined. Forty-six CWV and 42 control subjects with similar age from the general population were studied. Hematologic parameters, RS including; chest wheezing, night cough, night wheezing and cough, wheezing due to exercise (by Persian questionnaire), and PFT were assessed in all subjects. Total WBC count (p < 0.001), hematocrit, and mean corpuscular volume (MCV) were significantly higher (p < 0.05 and  0.001, respectively) but mean corpuscular hemoglobin concentration (MCHC) and the percent of monocyte were lower in veterans than control group (p < 0.001 and  0.01, respectively). All PFT values were also lower in CWV compared to control subjects (p < 0.001 for all cases). Maximal mid expiratory flow (MMEF) and maximal expiratory flow at 75% of forced vital capacity (MEF75) were the most affected PFT values in CWV and were 50% or lower of predicted values. All CWV reported respiratory symptoms, including; chest wheezing, night cough, night wheezing and cough, and wheezing due to exercise were higher in the veterans compared to control group (p < 0.001 for all cases). Increased total WBC count and RS but reduction in monocyte, MCHC, and PFT values were shown in CWV 27-30 years after exposure to SM. These results indicated profound hematologic (mainly WBC) and pulmonary effect of SM long time after exposure.

The clinical progression following a sulfur mustard-induced skin exposure is well documented in the literature. Upon skin contact and a characteristic latency period, sulfur mustard (SM) causes erythema, blister formation and ulceration, which is associated with wound healing disorders that may require surgical treatment. Here, we present a case report of accidental exposure to SM in a laboratory setting which required surgical treatment of the skin. The case was illustrated at close intervals over a period of two years and underlines that exposure to SM has to be taken into account when typical clinical symptoms occur. Moreover skin grafts appear to be effective in SM-induced non healing skin ulcerations.

Here we describe the synthesis of two Zr-based benzothiadiazole- and benzoselenadiazole-containing metal-organic frameworks (MOFs) for the selective photocatalytic oxidation of the mustard gas simulant, 2-chloroethyl ethyl sulfide (CEES). The photophysical properties of the linkers and MOFs are characterized by steady-state absorption and emission, time-resolved emission, and ultrafast transient absorption spectroscopy. The benzoselenadiazole-containing MOF shows superior catalytic activity compared to that containing benzothiadiazole with a half-life of 3.5 min for CEES oxidation to nontoxic 2-chloroethyl ethyl sulfoxide (CEESO). Transient absorption spectroscopy performed on the benzoselenadiazole linker reveals the presence of a triplet excited state, which decays with a lifetime of 9.4 μs, resulting in the generation of singlet oxygen for photocatalysis. This study demonstrates the effect of heavy chalcogen substitution within a porous framework for the modulation of photocatalytic activity.

BACKGROUND: The aim of this study was to investigate the association between the two most commonly used generic and disease specific health-related quality of life (HRQoL) measures in patients with chronic lung disease due to SM: Medical Outcomes Study Short Form 36-Item (SF-36) and St George\'s Respiratory Questionnaire (SGRQ).
METHODS: This is a secondary analysis of Iranian Chemical Warfare Victims Health Assessment Study (ICWVHAS) during October 2007 in Isfahan, Iran. In that survey, conducted in an outpatient setting, 292 patients with chronic lung disease due to SM were selected from all provinces in Iran. The total score and sub scores of correlations of SGRQ and SF-36 were assessed. Correlation of quality-of-life scores were evaluated using Pearson\'s coefficient.
RESULTS: Samples were 276 patients who were selected for our analysis. No significant correlation was found between the total score or sub scores of SF-36 and the total score or sub scores of SGRQ (p > 0.05).
CONCLUSIONS: In patients with chronic lung disease due to SM, the SF-36 and SGRQ assess different aspects of HRQoL. Therefore applying both of them together, at least in the research setting is suggested.
