Talking on a cellphone for long periods can carry certain risks, like dirty looks from those around you. But allergies?

In recent years, dermatologists have seen a small but growing number of people with itchy rashes along their jaw lines, face and ears which go away when cellphone use is discontinued.

The reason, studies suggest, is an allergy to metals in the phones, most often nickel.

Nationwide, nickel allergy afflicts about 3 percent of men and nearly 20 percent of women. Women are more likely to be affected because they are often sensitized to it by ear piercings and metal jewelry, said Dr. Clifford W. Bassett a New York City allergist and fellow of the American College of Allergy, Asthma and Immunology, who has treated the condition.

It’s unclear how many people develop allergic reactions to their phones. But the medical literature is rife with case studies. In a typical case, described by researchers at Brown University and published in the journal CMAJ in 2008, an 18-year-old developed a strange rash on the right side of his face. When his cellphone headset tested positive for nickel, he switched to a nickel-free phone, and the eruption cleared up. The researchers later tested 22 popular models of cellphones and found nickel in 10 of them, mostly in the headsets and menu buttons.

For those who suspect a metal allergy, a patch test at an allergist’s office can provide confirmation, Dr. Bassett said, and a simple swab test can reveal the presence of nickel in a phone or other product.

教育部不斷呼籲零體罰,但最近有老師在網路發起連署,爭取教師管教權,教育部昨天指出,教師不能體罰但有管教權,之前已對正向管教訂注意事項,對老師不能做的也採負面表列,最近會再跟縣市說明,加強宣導,相關內容也可再檢視。

今天是「世界兒童人權日」,教育部昨天以「零拒絕、零體罰、零霸凌」三零政策呼應世界兒童人權日,並呼籲學校、家長、社會應重視兒童人權,落實保障兒童人權。其中「零拒絕」就是學校不得拒絕任何一個兒童入學,並應將每個兒童帶上來,違規的校長考績不得考列甲等。

在「零體罰」方面,之前對國中學生問卷調查顯示,未曾被老師體罰比率,已從95年的57%,進步到98年的90%,顯見「正向管教」(零體罰)政策已逐步落實,但教育部更希望老師能夠正向管教,培養學生正確觀念。

教育部之前已訂正教師正向管教注意事項,對老師管教不能採取的措施,採負面表列,例如不能打學生、用言語羞辱學生等,學校可參考,再依校規訂輔導管教辦法,有可能老師不清楚,將再請縣市、學校轉達。

口腔癌是台灣男性25到44歲的頭號癌症,禍首就是檳榔,雖然最近五年國內嚼食檳榔率有下降趨勢,不過國內口腔癌發生率五年內增加了30%,死亡率成長了25%,主要是因為接受口腔篩檢的人偏低,醫師提醒紅唇族與癮君子,定期接受檢查,才能預防勝於治療

台灣口腔癌問題日益嚴重,根據統計,台灣一年新增5352位口腔癌與咽癌病人,都跟檳榔脫不了關係,更有高達四萬四千多名口腔病患需要持續就醫,不僅發生率持續成長、男性發生率更高居華人第一,而且已經是台灣25到44歲男性最容易發生的癌症。

雖然檳榔對健康危害的問題開始被重視,根據國健局統計,單就男性來看,檳榔嚼食率五年內下降9%,不過口腔癌發生率卻增加三成,死亡率也增加兩成五,台灣檳榔防治暨口腔癌防治聯盟主席韓良俊表示,主因就是認知仍不足,接受篩檢的人偏低,只有一成四,有不少病患到院就醫,已經是口腔癌晚期,治療很不容易。

「在台灣來講六成以上都是比較晚期,所謂晚期就是第三期、第四期,第四期幾乎都很不容易治,第三期要治療也要很大範圍去切除、去開刀,但是這種第三、第四期的占了六成以上。」

口腔癌儼然成為國內中壯年頭號殺手,統計國內檳榔族約有150到170萬人,其中多數還有吸菸習慣,增加罹患口腔癌風險,,醫師提醒,有吃檳榔與抽煙習慣的民眾,定期進行口腔篩檢,最好是儘量少碰檳榔與菸,喝酒控制在適量就好。
