Thomas Hodgkin's journey through Spain in 1863 and 1864

In 1863 and 1864, Thomas Hodgkin travelled to Morocco, accompanying his close friend Sir Moses Montefiore, who stopped in Madrid on the way there and back to attend an audience with the Queen of Spain. Thomas Hodgkin's impressions of Spain were recounted in his book Narrative of a Journey to Morocco. The book reveals new aspects of Hodgkin's personality as well as his capacity for observation. It also describes Spain in the second half of the nineteenth century. Thus Thomas Hodgkin was a witness to one of the most vivid periods of the history of the country. The paper considers both aspects of Hodgkin's commentaries on Spain.     

Pseudocyst of the auricle: a histologic perspective

OBJECTIVE: The aim of the study is to describe the histologic spectrum in the pseudocyst of the auricle and to identify any consistent histologic features of this condition. STUDY DESIGN: A prospective study was performed in which the tissue specimen from patients with pseudocyst of the auricle treated at the Department of Otolaryngology, Singapore General Hospital during a 1-year period was sent for histology. METHODS: Consecutive patients with pseudocyst of the auricle who were treated had their tissue specimen sent for histology. These specimens were independently reviewed by one consultant pathologist. RESULTS: All 16 specimens revealed an intracartilaginous cyst devoid of epithelial lining. Interestingly, there were consistent perivascular mononuclear infiltrates of lymphocytes evident in the connective tissue layer just superficial to the anterior segment of the cartilage. CONCLUSION: Pseudocyst of the auricle is a benign condition predominantly affecting young Asian males. Histology characteristically reveals an intracartilaginous cyst devoid of epithelial lining, and there are no pathognomonic features. We postulate that an inflammatory response is crucial to the development of this condition on the basis of a consistent perivascular inflammatory response seen in all our specimens.     

Agricultural and residential pesticides in wipe samples from farmworker family residences in North Carolina and Virginia

Children of farmworkers can be exposed to pesticides through multiple pathways, including agricultural take-home and drift as well as residential applications. Because farmworker families often live in poor-quality housing, the exposure from residential pesticide use may be substantial. We measured eight locally reported agricultural pesticides and 13 pesticides commonly found in U.S. houses in residences of 41 farmworker families with at least one child < 7 years of age in western North Carolina and Virginia. Wipe samples were taken from floor surfaces, toys, and children's hands. We also collected interview data on possible predictors of pesticide presence, including characteristics of the household residents, cleaning practices, and characteristics of the home. All families were Spanish-speaking, primarily from Mexico. Results indicate that six agricultural and 11 residential pesticides were found in the homes, with agricultural, residential, or both present in 95% of homes sampled. In general, residential pesticides were more commonly found. Presence of both types of pesticides on the floor was positively associated with detection on toys or hands. Agricultural pesticide detection was associated with housing adjacent to agricultural fields. Residential pesticide detection was associated with houses judged difficult to clean. Although the likelihood of agricultural pesticide exposure has been considered high for farmworker families, these results indicate that residential pesticide use and exposure in this population merit further study.     

The validity and reliability of chinese frontal assessment battery in evaluating executive dysfunction among Chinese patients with small subcortical infarct

OBJECTIVES: Frontal Assessment Battery (FAB) is a valid and reliable screening test for evaluating executive dysfunction among whites with frontal and subcortical degenerative lesions. We studied the properties of a Chinese version of FAB (CFAB) in evaluating executive dysfunction among Chinese stroke patients with small subcortical infarct. METHODS: Concurrent validity was evaluated using Wisconsin Card Sorting Tst (WCST) and Mattis Dementia Rating Scale-Initiation/Perseveration Subset (MDRS I/P) among 41 controls and 30 stroke patients with small subcortical infarct. Discriminant validities of CFAB and its subitems were compared with those of Mini-Mental State Examination (MMSE). Internal consistency, test-retest, and interrater reliability of CFAB were evaluated. RESULTS: The CFAB had low to good correlation with various executive measures: MDRS I/P (r = 0.63, p < 0.001), number of category completed (r = 0.45, p < 0.001), and number of perseverative errors (r = -0.37, p < 0.01) of WCST. Among the executive measures, only number of category completed had significant but small contribution (6.5%, p = 0.001) to the variance of CFAB. A short version of CFAB using three items yielded higher overall classification accuracy (86.6%) than that of CFAB full version (80.6%) and MMSE (77.6%). Internal consistency (alpha = 0.77), test-retest reliability (rho = 0.89, p < 0.001), and interrater reliability (rho = 0.85, p < 0.001) of CFAB were good. CONCLUSION: Although CFAB is reliable, it is only moderately valid in evaluating executive dysfunction among Chinese stroke patients with small subcortical infarct. The clinical use of CFAB in the evaluation of executive dysfunction among this group of patients cannot be recommended at this stage.     

Neurothekeoma of the paranasal sinuses in a 3-year-old boy

Neurothekeoma is a benign soft tissue tumor commonly located on the skin. In this report, a 3-year-old boy presented with restricted right eye movement and decrease in visual acuity. The patient was found to have a 6-cm neurothekeoma involving the maxillary and ethmoid sinuses. To our knowledge, this is the first reported case of neurothekeoma with involvement of the maxillary and ethmoid sinuses. This uncommon lesion should be considered as the differential diagnosis of pediatric soft tissue tumors in the head and neck region.
