Skin problems after a tsunami

BACKGROUND: On December 26, 2004, the biggest earthquake for 40 years, measuring 9.0 on the Richter scale, triggered a tsunami that pounded the coastal areas of South Asia and East Africa. The effects of the tsunami on skin conditions have not been evaluated. OBJECTIVE: To determine the influence of the tsunami on skin conditions by evaluating the skin problems of patients presenting at hospitals after the tsunami. METHODS: Between 5 and 25 January 2005, two dermatologists evaluated patients who complained of skin problems at an outpatient clinic and emergency room of a general hospital in Banda Aceh, Aceh Province, Indonesia. RESULTS: The total number of patients that presented during the study period was 235 (131 males and 104 females), and they had a total of 265 skin problems. In terms of age distribution, most subjects were in their fourth decade (23.0%), followed by the third (22.6%) and fifth decade (16.6%). The most prevalent skin problems were infections-infestations (32.5%), followed by eczemas (29.8%) and traumatic skin disorders (29.4%). In males, traumatic skin disorders were most common. The great majority of infection-infestation cases involved superficial fungal infections. Contact dermatitis accounted for three-quarters of eczema cases, and mainly involved the arms (40.0%) and legs (27.1%). The majority of traumatic skin disorders were lacerations, punctures and penetrations, and the feet (44.7%) and hands (18.8%) were most frequently affected. CONCLUSIONS: Unhygienic conditions, exposure to a hazardous environment and contact with various objects during and after the tsunami probably increased the prevalence of infections-infestations, traumatic skin disorders and contact dermatitis. To prevent these problems and associated secondary bacterial infections, health-related education and early medical management are required.     

Pick’s disease with Pick bodies combined with progressive supranuclear palsy without tuft‐shaped astrocytes: A clinical,neuroradiologic and pathological study of an autopsied case

We report clinical, neuroradiologic features, and neuropathologic findings of a 76‐year‐old man with coexistent Pick’s disease and progressive supranuclear palsy. The patient presented with loss of recent memory, abnormal behavior and change in personality at the age of 60. The symptoms were progressive. Three years later, repetitive or compulsive behavior became prominent. About 9 years after onset, he had difficulty moving and became bed‐ridden because of a fracture of his left leg. His condition gradually deteriorated and he developed mutism and became vegetative. The patient died from pneumonia 16 years after the onset of symptoms. Serial MRI scans showed progressive cortex atrophy, especially in the bilateral frontal and temporal lobes. Macroscopic inspection showed severe atrophy of the whole brain, including cerebrum, brainstem and cerebellum. Microscopic observations showed extensive superficial spongiosis and severe neuronal loss with gliosis in the second and third cortical layers in the frontal, temporal and parietal cortex. There were Pick cells and argyrophilic Pick bodies, which were tau‐ and ubiquitin‐positive in neurons of layers II–III of the above‐mentioned cortex. Numerous argyrophilic Pick bodies were observed in the hippocampus, especially in the dentate fascia. In addition, moderate to severe loss of neurons was found with gliosis and a lot of Gallyas/tau‐positive globus neurofibrillary tangles in the caudate nucleus, globus pallidus, thalamus, substantia nigra, locus coeruleus and dentate nucleus. Numerous thorned‐astrocytes and coiled bodies but no‐tuft shaped astrocytes were noted in the basal ganglion, brainstem and cerebellar white matter. In conclusion, these histopathological features were compatible with classical Pick’s disease and coexistence with progressive supranuclear palsy without tuft‐shaped astrocytes.     

伴有LADD综合征的角膜缘干细胞缺乏

泪管-耳-牙-指（趾）（LADD）综合征是一种具有多种表现的常染色体显性遗传疾病。最初在1967年由Levy报道。1例双侧泪液系统缺失、杯状耳、干嘴，以及牙、手臂和指（趾）异常的单发病例。之后一些新发现的临床表现，如肾脏异常、唾液腺缺乏、先天性髋脱位、先天性裂孔疝和横膈疝、感觉性耳聋和传导性耳聋、牙发育不全、四肢异常、口腔干燥和眼干都被报道与此综合征有关。

人Uroplakin Ⅱ启动子用于靶向性基因治疗膀胱癌的实验研究

目的探讨利用人UroplakinⅡ(hUPⅡ)启动子进行靶向性基因治疗膀胱癌的可能性。方法将hUPⅡ启动子和肿瘤坏死因子-α(TNF-α)克隆到腺病毒载体Ad5中,构建重组体pAd-hUPⅡ-TNF。转染细胞293后产生复制缺陷型的重组腺病毒,感染膀胱癌细胞系BIU-87,检测TNF-α对BIU-87细胞体外生物学行为及体内成瘤性的影响。结果成功构建pAd-hUPⅡ-TNF重组腺病毒载体,转染细胞293获得复制缺陷型重组腺病毒。BIU-87细胞经重组腺病毒感染后可产生高浓度的TNF-α,并降低BIU-87的生长速度。感染腺病毒的BIU-87培养液可抑制L929细胞的生长。裸鼠原位膀胱肿瘤动物模型实验结果表明膀胱灌注重组腺病毒48h后,裸鼠尿液含高浓度的TNF-α,4周后腺病毒组膀胱重量和体积明显低于对照组(P<0.01)。结论hUPⅡ启动子TNF-α为治疗基因的重组腺病毒可特异性使膀胱癌细胞系BIU-87产生高浓度的TNF-α,并降低BIU-87和L929细胞的生长速度。重组腺病毒可使裸鼠尿内含高浓度的TNF-α,并可抑制裸鼠原位膀胱肿瘤动物模型膀胱癌细胞的成瘤性。
