Dermatoses of the scalp.

By judicious consideration of the clinical appearance, by direct examination with magnification, and by culture results, skin biopsy, and other laboratory results, the clinician is able to diagnose most pathological conditions of the scalp. The scalp participates in many systemic disorders and frequently is the chief site of involvement. Similarly, many generalized disorders limited to the skin exhibit their most typical manifestations in the scalp. Whenever a diagnosis eludes the investigator, more than likely he or she has not considered all of the etiological possibilities or has not pursue

Increased risk of salivary gland tumors after low-dose irradiation.

OBJECTIVE: To assess the risk of neoplastic development among persons exposed to scalp irradiation. STUDY DESIGN: Historical cohort study initially; prospective follow-up subsequently. METHOD: Two control groups--population and siblings--matched for age, sex, ethnic origin, and year of immigration. Follow-up from time of irradiation (1950s) until the end of 1991. Linkage with nationwide cancer registry. RESULTS: A 4.5-fold incidence of cancer (P < .01) and a 2.6-fold increase of benign tumors were noted. The mean length of latency period until tumor development was 11 years for malignant tu

Analysis of genetic polymorphism of the HLA-B and HLA-DR loci in patients with dermatophytic onychomycosis and in their first-degree relatives.

Onychomycosis is known to have predisposing factors and a high prevalence within families that cannot be explained by within-family transmission. We determined the frequency of HLA-B and HLA-DR haplotypes in 25 families of Mexican patients with onychomycosis in order to define the role of the class II major histocompatibility complex (MHC) in genetic susceptibility to this infection. Seventy-eight subjects participated in the study, 47 with onychomycosis and 31 healthy individuals. The frequencies of the HLA-B and HLA-DR haplotypes were compared with those found in first-degree relatives witho

Variations with time and age in the risks of solid cancer incidence after radiation exposure in childhood.

The Japanese atomic bomb survivor incidence data set and data on five other groups exposed to ionizing radiation in childhood are analysed and evidence found for a reduction in the radiation-induced relative risk of cancers other than leukaemia with increasing time since exposure. Overall, reductions of 5.7-6.1 per cent per year of time since exposure are indicated, depending on the time at which the reduction is presumed to start, and all the reductions are statistically significant at the 5 per cent level. There is no significant heterogeneity in the speed of the reductions in relative risk

Common Cutaneous Infections: Patient Presentation, Clinical Course, and Treatment Options.

The instrument measured the correctness of exclusion and inclusion decisions (using American Academy of Pediatrics/American Public Health Association guidelines as gold standard) according to varying levels of fever, disease …

Clinical Outcome After Permanent Pacemaker Implantation in Patients With a High Percentage of Ventricular Pacing.

Previous reports have suggested that right ventricular apical pacing may lead to cardiac dysfunction. Septal pacing is thought to be superior to apical pacing in the prevention of cardiac dyssynchrony, however, there have been no reports on the contribution of septal pacing to improving clinical outcome.We retrospectively evaluated factors associated with cardiac events in patients with right ventricular pacing.The study population consisted of 256 consecutive patients newly implanted with permanent pacemakers and followed-up for 29 ± 18 months. Cardiac events, consisting of cardiac death or h

Cancer risks from medical radiation.

About 15% of the ionizing radiation exposure to the general public comes from artificial sources, and almost all of this exposure is due to … ral nervous system, skin, and breast as well as leukemia have been associated with radiotherapy for tinea capitis, enlarged tonsils or thymus gland, other benign conditions of the head and neck, or benign breast diseases.

Fortification of Carica papaya fruit seeds to school meal snacks may aid Africa mass deworming programs: a preliminary survey.

BACKGROUND: Soil transmitted helminths (STHs) are among the world's neglected tropical diseases. Morbidity due to STHs is greatest in school … arm (13.2 to 13.1). Interestingly the papaya group showed a significant reduction of children with Tinea capitis (ringworms) (54.4 to 34%, p < 0.002) as compared to the albendazole arm that showed an increase in ringworm infestation though not statistically significant (39.7 to 64.7% p = 0.608). CONCLUSION: Papaya seed fortified porridge had a significant eff …

According to the patient's medical history, he was treated for tinea capitis with radiotherapy of the scalp at the age of 7, with temporary hair-loss and subsequent total re-growth. Additionally, during the last 7 years he was diagnosed with mental depression and treated accordingly. The histology revealed typical epithelioi …

Clinical Manifestations of Human Exposure to Fungi.

Biological particles, along with inorganic gaseous and particulate pollutants, constitute an ever-present component of the atmosphere and surfaces. Among these particles are fungal species colonizing almost all ecosystems, including the human body. Although inoffensive to most people, fungi can be responsible for several health problems, such as allergic fungal diseases and fungal infections. Worldwide fungal disease incidence is increasing, with new emerging fungal diseases appearing yearly. Reasons for this increase are the expansion of life expectancy, the number of immunocompromised patien

Risk of basal cell and squamous cell skin cancers after ionizing radiation therapy. For The Skin Cancer Prevention Study Group.

BACKGROUND: Human evidence that ionizing radiation is carcinogenic first came from reports of nonmelanoma skin cancers (NMSCs) on the hands of workers using early radiation devices. An increased risk of NMSC has been observed among uranium miners, radiologists, and individuals treated with x rays in childhood for tinea capitis (ringworm of the scalp) or for thymic enlargement; NMSC is one of the cancers most strongly associated with the atomic bombing of Hiroshima and Nagasaki. Although exposure to ionizing radiation is a known cause of NMSC, it is not yet clear whether therapeutic radiation c…

Estimation of cancer risks from radiotherapy of benign diseases.

BACKGROUND: The effective-dose method which was proposed by the ICRP (International Commission of Radiation Protection) for the estimation of risk to the general population from occupational or environmental, low-dose radiation exposure is not adequate for estimating the risk of cancer induction by radiotherapy of malignant or nonmalignant diseases. METHODS: The risk of cancer induction by radiotherapy of benign diseases should be based on epidemiologic data directly derived from follow-up studies of patients who had been given radiotherapy for nonmalignant diseases in the past. RESULTS: Ris

A phase III randomized crossover trial of plerixafor versus G-CSF for treatment of WHIM syndrome.

BACKGROUNDWarts, hypogammaglobulinemia, infections, and myelokathexis (WHIM) syndrome is a primary immunodeficiency disorder caused by heterozygous gain-of-function CXCR4 mutations. Myelokathexis is a kind of neutropenia caused by neutrophil retention in bone marrow and in WHIM syndrome is associated with lymphopenia and monocytopenia. The CXCR4 antagonist plerixafor mobilizes leukocytes to the blood; however, its safety and efficacy in WHIM syndrome are undefined.METHODSIn this investigator-initiated, single-center, quadruple-masked phase III crossover trial, we compared the total infection s
