Abstract
Cooking with biomass fuels has been reported to have adverse effects on health. This study aims to explore the association between cooking with biomass fuels and vision impairment among Chinese older adults aged 65 years and above. This cohort study drew on data from the 2011/2012 wave and the 2014 follow-up wave of the Chinese Longitudinal Healthy Longevity Survey. Participants' visual function was examined through a vision screening test. Exposure to indoor biomass fuels was self-reported. Cox proportional hazards models were applied to explore the relationship between biomass fuel use and vision impairment. Additionally, we compared the risk of vision impairment between participants who switched cooking fuel types and those who did not. Subgroup and interaction analyses were conducted to explore the potential effect modifiers. A total of 4711 participants were included in this study. During the follow-up, 1053 (22.35%) participants developed vision impairment. Cooking with biomass fuels increased the risk of vision impairment by 40% (hazard ratio [HR]: 1.40, 95% confidence interval [CI]: 1.21-1.61). Participants who switched from clean fuels to biomass fuels had a greater risk of vision impairment than persistent clean fuel users (HR: 1.44, 95% CI: 1.03-2.00). Greater effect estimates were found in participants who lived in eastern and central China and urban residents. Cooking with biomass fuels resulted in a greater risk of vision impairment among Chinese older adults. This risk also existed in those who changed their cooking fuels from clean fuels to biomass fuels. Further studies with an objective assessment of biomass fuel combustion are required to confirm our findings.

Abstract
The genus Ficus belongs to the Moraceae (the mulberry family). Figs can cause irritant or phototoxic reactions. Phytophotodermatitis is a common cutaneous phototoxic reaction. Contact with plant-derived phototoxic substances (furocoumarins or psoralens) followed by sunlight exposure produces the clinical lesions. Here, we present a case of phytophotodermatitis after contact with fig fruits and leaves. The vesicular dermatitis was primarily located in areas of vitiligo.

Abstract
The association between polymorphisms of COX-2 -765G>C and p53 codon 72, and oral squamous cell carcinoma (OSCC) remains unclear. We investigated the associations between COX-2 and p53 polymorphisms, oral precancerous lesions (OPL), and OSCC. Demographic data and substance use (smoking, drinking, and betel quid chewing) data were collected from 297 patients with OSCC, 70 with oral leukoplakia (OL), 39 with oral submucosal fibrosis (OSF), and 280 healthy controls. COX-2 and p53 polymorphisms were determined by PCR-RFLP methods. A significantly higher proportion of OSCC and OPL patients were male, and frequent habitual users of the three substances. No association was found between p53 and COX-2 polymorphisms, ethnicity, and gender. Polymorphisms of p53 were not associated with OSCC development and malignant potential of OPL, OSF, and OL. The frequency of COX-2 -765G/G genotype was significantly higher in healthy controls (chi(2)=93.83, p<0.0001). After adjusting for possible confounding factors, COX-2 -765C allele vs. -765G/G genotype (OR=0.22, 95%CI=0.12-0.39) was a protective factor against OSCC development, but was a risk factor for malignant potential of OSF (OR=3.20, 95%CI=1.32-8.94) and OL (OR=6.73, 95%CI=2.84-19.87). We suggest that COX-2 -765G>C polymorphisms play a different role in OSCC development than in malignant potential of OSF and OL. However, p53 codon 72 polymorphisms show no such correlation.

Abstract
Myoga is a fragrant plant which is the special product of Japan and is cultivated throughout Japan. According to our earlier investigation (unpublished data) of myoga cultivators in Japan, 8 of 35 cultivators experienced contact dermatitis in the harvest season. The purpose of this study was to assess the allergenicity of myoga and its major volatile components. The volatile components of myoga were analyzed by gas chromatograph (GC). They included a-pinene, beta-pinene and R-(+)-limonene. We performed a toxicity study of each of the major fragrant components of myoga using acute dermal irritation assays and the Guinea-Pig Maximization test (GPMT) in order to probe the mechanism of allergic contact dermatitis. In acute dermal irritation assays, alpha-pinene, beta-pinene and limonene showed positive responses at concentrations of 4%; limonene oxide at 20% and myoga showed a positive response at concentrations of 100%. From the results of the GPMT, according to Kligman scores, limonene oxide was identified as an extreme skin sensitizer and myoga as a mild skin sensitizer. The results of the present study show that R-(+)-limonene is the most important allergen amongst the chemical components of myoga, and we consider it to be the reason why myoga cultivators experience allergic contact dermatitis.

Abstract
To investigate the incidence of allergic contact dermatitis (ACD) to plants in our area, we reviewed the records of the patients that were studied in the Allergic Contact Unity of our hospital in the last 7 years (2248 patients). We found 69 cases of positive patch tests to plant allergens, representing 3% of all the patients in that period. Diallyl disulfide was the most frequent allergen (47 cases), involving mainly middle-aged housewives with chronic hand eczema. Positive tests to sesquiterpene lactone mix (SL mix) were found in 11 patients, mostly middle-aged rural workmen with an airborne clinical pattern. Other allergens detected were lichens, primin, tulipalin A and wood. These results show a high incidence of ACD to diallyl disulfide that, in our opinion, should be tested in all housewives or cooks with chronic hand eczema. The predominance of the classical airborne pattern of allergy to SL in our study may be because the airborne way of allergen exposure in our area, with a high percentage of rural population, is the most frequent, and it makes it important to remember this possibility in the differential diagnosis of photosensitivity.

Abstract
Assuming that airborne particles and pollutants are important contributing factors in the development of exercise-induced bronchoconstriction (EIB), we performed a case-control study including 63 tea workers (36 men and 27 women, aged 36-55, duration of employment 3-30 years) and an equal number of office workers, matched by sex and age. Exercise-induced respiratory symptoms were recorded in a questionnaire. Skin prick tests, spirometry, as well as exercise and histamine challenge were carried out. Environmental measurements were performed on site during the work shifts. The prevalence of self-reported exercise-induced respiratory symptoms and EIB did not differ significantly between the exposed and control group (41.6% vs 36.8%, and 6.4% vs 4.8%, respectively). In both exposed and control workers, EIB was strongly linked to asthma (P < 0.01). In the exposed workers it was significantly associated with positive family history of asthma (P < 0.01) and positive family history of atopies (P < 0.05), whereas in the exposed smokers it was significantly related to smoking duration (P < 0.05). Bronchial reaction to exercise in the exposed smokers was significantly greater than in control smokers (P < 0.05). Self-reported exercise-induced respiratory symptoms were weakly associated with EIB, with a large proportion of false positive and a low proportion of false negative results in both groups.

Abstract
Mexico has cultivated opium poppy since before the 1900's and has been an important transit route for South American cocaine for decades. However, only recently has drug use, particularly injection drug use, been documented as an important problem. Heroin is the most common drug used by Mexican injection drug users (IDUs). Increased cultivation of opium poppy in some Mexican states, lower prices for black tar heroin and increased security at U.S.-Mexican border crossings may be contributing factors to heroin use, especially in border cities. Risky practices among IDUs, including needle sharing and shooting gallery attendance are common, whereas perceived risk for acquiring blood borne infections is low. Although reported AIDS cases attributed to IDU in Mexico have been low, data from sentinel populations, such as pregnant women in the Mexican-U.S. border city of Tijuana, suggest an increase in HIV prevalence associated with drug use. Given widespread risk behaviors and rising numbers of blood borne infections among IDUs in Mexican-U.S. border cities, there is an urgent need for increased disease surveillance and culturally appropriate interventions to prevent potential epidemics of blood borne infections. We review available literature on the history of opium production in Mexico, recent trends in drug use and its implications, and the Mexican response, with special emphasis on the border cities of Ciudad Juarez and Tijuana.

Abstract
Bhurgri Y (2005) have studied the time trends in the site specific oral cancer incidence in the Karachi South, a sample population of Pakistan with a representation of all ethnic and socio-economic groups of the country. Oral cancer ranks 6th world-wide. However, 58% of the cases are concentrated in South and Southeast Asia (Nair et al; 2004). In Karachi, it ranks 2nd in all malignancies among both males and females, with the highest reported incidence in the world. In the absence of alcohol use, chewing of products of betel, areca and tobacco remain the main etiological risk factors. These products include paan, chaalia, gutka and naswar. Because of the ancient history of these products, their use is socially acceptable in all sections of South Asian society.

Abstract
(1) Amphetamine-like drugs are not only authorised for use as appetite suppressants. (2) Bupropion, otherwise known as amfebutamone, is licensed as an aid to smoking withdrawal. It has amphetamine-like adverse effects, such as seizures; in addition it causes hypersensitivity reactions. (3) Benfluorex is sold in France as an adjunctive treatment for hypertriglyceridemia and diabetes with overweight. The lack of data on its adverse effects is hardly reassuring. A case of severe cardiac valve disease has been published. (4) The ephedrine derivatives norephedrine (phenylpropanolamine) and pseudoephedrine are used in ENT as decongestants because of their vasoconstrictive properties. They expose patients to serious cardiovascular risks. Ephedrine and plants belonging to the genus Ephedra (used in freshly prepared appetite suppressant mixtures) have negative risk-benefit ratios. (5) Methylphenidate is used as a psychostimulant in patients with narcolepsy and children with attention-deficit disorder. It can lead to serious mental and physical dependence.

Abstract
In recent years, the use of herbal preparations containing Ephedra has increased and so has the number of reported negative health effects. Ephedra products are used as a slimming aid, (sports) performance enhancer, stimulant during long working hours and as a plant-based ecstasy-surrogate in the party scene. The health effects caused by the use of Ephedra products are mainly restlessness, agitation, tachycardia and palpitations. The most important risk factors are the relatively high amounts of Ephedra alkaloids in the preparations available, the varying concentrations within different batches of the same product, the relatively high risk of voluntary overdosing in order to improve results and the occurrence of interactions with the concurrent use of other stimulants and medicines.

Abstract
BACKGROUND Ephedra is widely used in dietary supplements that are marketed to promote weight loss or increase energy; however, the safety of this product has been questioned because of numerous case reports of adverse events. OBJECTIVE To compare the risk for adverse events attributable to ephedra and other herbal products. DESIGN Comparative case series. SETTING American Association of Poison Control Centers Toxic Event Surveillance System Database Annual Report, 2001. MEASUREMENTS The relative risk and 95% confidence interval for experiencing an adverse reaction after ephedra use compared with other herbs. This risk was defined as the ratio of adverse reactions to ephedra versus other products, divided by the ratio of their relative use in the United States. RESULTS Products containing ephedra accounted for 64% of all adverse reactions to herbs in the United States, yet these products represented only 0.82% of herbal product sales. The relative risks for an adverse reaction in persons using ephedra compared with other herbs were extremely high, ranging from 100 (95% CI, 83 to 140) for kava to 720 (CI, 520 to 1100) for Ginkgo biloba. CONCLUSIONS Ephedra use is associated with a greatly increased risk for adverse reactions compared with other herbs, and its use should be restricted.

PURPOSE To report a rare case of multiple cactus spines embedded deep in the cornea that were removed with the aid of a fiberoptic illuminator. DESIGN Interventional case report. METHODS A 20-year-old man had an accidental ocular injury of the right eye when he hit a household miniature cactus plant. There were 80 to 90 spiculated foreign bodies embedded in the cornea, some of them even penetrating the anterior chamber. RESULTS Removal of the foreign bodies was performed with the aid of a fiberoptic illuminator, which was chosen because it provides superior visualization of the semitranslucent spines. No residual corneal spines were found postoperatively. CONCLUSIONS Household miniature cactus plants can cause corneal injury, with multiple foreign bodies that can be difficult to localize and remove. The use of a fiberoptic illuminator in such a situation is simple and effective.

Abstract
BACKGROUND The purpose of this study was to review patients treated for penetrating Phoenix date palm injuries. Documentation of the clinical behaviour of these injuries was sought as they have different clinical outcomes to other foreign body injuries. METHODS Data was collected via a retrospective review of patient files and imaging studies of all patients with foreign body injury admitted to the Orthopaedic Service of Starship Children's Hospital between 1992 and 1997. RESULTS Of 250 patients admitted with foreign body injuries, 21 cases were identified as caused by the Phoenix date palm. The age range was 5 to 12 years. There was a median delay of 43 days between the time of injury and presentation to hospital. An average of 1.3 operations were performed on each patient. Ultrasound was used in 12 cases, foreign body was identified in 10 patients--a sensitivity of 83%. Intraoperative ultrasound was also found to be beneficial in three of these cases. CONCLUSIONS Phoenix date palm injuries often have a protracted course. The initial diagnosis and treatment of such injuries is often delayed. Fracturing and fragmentation of the barbs may occur and multiple surgical procedures may be required to remove all of the foreign material. The Phoenix date palm barbs may cause a severe tissue reaction with sterile granulomatous synovitis and bony pseudotumour formation. A high level of suspicion on history taking and surgical exploration is needed. Total synovectomy for delayed joint or tendon sheath involvement may be required when fragmentation has occurred. Ultrasound has higher sensitivity for detection of thorn foreign bodies than magnetic resonance imaging.

Abstract
To evaluate causes of itch, commercial 'itching powders' were sought for evaluation. Only one product, produced in Germany and consisting of ground rose hips, is currently sold in novelty shops in the Boston area. These plant fibres appear to provoke itch and prickle sensations by non-allergic mechanical stimulation, similar to the action of wool fibres.

Hausen BM. Allergic contact dermatitis from a wooden necklace. Am J Contact Dermat 1997; 8:185-7.

Abstract
A 36-year-old female kitchenworker twice developed eczematous lesions corresponding exactly to the area around her neck where she had worn a wooden necklace. Contact dermatitis lasted longer than 1 week. The necklace consisted of 42 brown wooden beads and 63 other wooden parts, 0.5 to 3 cm diameter. Most parts could be identified as Cocobolo wood, Brazilian and East Indian rosewood, and teak. Patch tests with the pure constituents gave +3-reactions to three dalbergions and obtusaquinone, which are known to be the sensitizers of Cocobolo and the above-mentioned rosewoods. Because of these test results, the identification of the species by eye examination could be corroborated. Further detailed questioning revealed that the patient had played a recorder, probably made from Cocobolo (Dalbergia retusa), when a child, to which she unknowingly became allergic.
