Psoriasis in childhood and adolescence: evaluation of demographic and clinical features

BACKGROUND: The present study was aimed to define the gender ratio, familial occurrence, age of onset, precipitating factors, clinical types, nail and joint involvement of psoriasis in childhood and adolescence in Turkey. METHODS: A total of 61 children with psoriasis under 18 years old were evaluated retrospectively, for age, gender, age of disease onset, family history, concomitant disease, the clinical type of psoriasis, clinical localization, nail and joint involvement and treatment modalities. RESULTS: Of the patients, 23 (37.70%) were boys and 38 (62.30%) were girls. Mean age was 9.28 +/- 4.02 years in girls and 11.18 +/- 3.85 years in boys (9.96 +/- 4.03 years in all children). Mean age at the onset of the disease was 6.81 +/- 4.11 years in girls and 7.03 +/- 4.28 years in boys (6.89 +/- 4.14 years in all patients). In 14 (23%) cases, a positive family history was detected. The most frequent probable triggering factors were upper respiratory tract infections (14.8%) and positive throat culture for A group ss-hemolytic streptococcus (21.3%). Frequency of emotional stress and psychiatric morbidity were 54% and 9.8%, respectively. The most frequent localizations at onset were trunk (44.3%), extremities (54.0%), and scalp (36.0%). Three children (4.9%) had a history of dissemination from psoriatic diaper rash. In total, 51 (83.6%) patients presented with psoriasis vulgaris, eight (13.1%) with generalized pustular psoriasis, and the remaining two (3.3%) with erythrodermic psoriasis. CONCLUSION: The incidence of psoriasis among dermatological patients in childhood and adolescence was 3.8%. The disease tends to appear earlier in girls than boys. The authors suggested that stress and upper respiratory infections are the most important triggering factors in childhood and adolescence psoriasis.

Disc haemorrhages and glaucoma in a general ophthalmic practice

The composition of the clientele from an ophthalmological practitioner's office is described with special reference to the occurrence of glaucoma and disc haemorrhages (h in singular; hh in plural). This study could not be planned as an epidemiological survey and gives no clue to sensitivity or specificity of hh in glaucoma. During a period of about 10 years ending with 1986 there were 731 patients with h and/or glaucoma. When detected, 185 patients had h but no glaucoma, 33 had both h and glaucoma and 513 had glaucoma but no h. During the follow-up period hh were detected in 83 cases of glaucoma, and glaucoma developed in 27 cases with hh. The detection rate of hh among glaucoma was low but steady, indicating that hh may occur at any stage of the glaucoma process. This study shows no predilection for hh in cases with general hypertension or diabetes, nor is the frequency of hh among pseudoexfoliation cases significantly lower than among cases without this stigma.     

Repair of bile duct defect with full-thickness vascularized jejunal patch

The use of a vascularized jejunal patch for the reconstruction of bile duct injuries is presented. The method has been used in 1 patient with a common bile duct stricture and in 1 patient with a noncircumferential bile duct defect. The procedure has the advantages of technical simplicity, primary mucosal coverage, lasting elasticity, and minimal risk for stricture formation.

Resumen Se presenta el uso de un parche vascularizado de yeyuno para la reconstrucción de lesiones del canal colédoco. Se reseca un segmento móvil del yeyuno lo suficientemente amplio para cubrir el defecto, asegurándose de que existe buena irrigación para el segmento, visualizando los vasos por transiluminación con luz ordinaria. La continuidad del intestino es restablecida mediante anastomosis término-terminal. Se utiliza la parte mesentérica del segmento intestinal, el cual es ascendido por vía retrocólica. Se sutura mucosa con mucosa con una sola capa de puntos separados de ácido poliglicólico 5-0. Se coloca un tubo-en-T para drenaje, el cual es retirado a las 6 semanas. El método ha sido utilizado en un caso de estenosis del colédoco y en un caso con un defecto circunferencial del mismo canal biliar. El procedimiento tiene la ventaja de la simplicidad técnica, la cobertura primaria de la mucosa, la elasticidad permanente y un mínimo riesgo de que se produzca estenosis.

Résumé L'emploi d'un patch jéjunal bien vascularisé pour traiter les blessures de la voie biliaire fait l'objet de l'article. La méthode a été utilisée pour un cas de sténose de la voie biliaire principale et un cas de plaie n'intéressant pas la totalité de la circonférence du canal biliaire. Elle a pour avantages sa simplicité technique et le fait qu'elle assure une couverture muqueuse, sa persistante élasticité et le fait qu'elle présente un risque réduit de sténose.

     

Can a failed ileal pouch anal anastomosis be left in situ?

OBJECTIVE: Failure after ileal pouch-anal anastomosis (IPAA) is reported with a frequency of 10-20%. The failed IPAA can be excised or defunctioned. Indications for excision and further management of an indefinitely diverted pouch are poorly described. The aim of the present investigation was to investigate pouch-related problems and the histopathological pattern of the pouch mucosa in this group of patients. METHOD: In a cohort of 620 patients having IPAA with a median follow-up of 14 years, 56 patients with failure were identified. The patients with defunctioned pouches were assessed with regard to pouch-related problems and endoscopy with biopsies was performed. Biopsies were stained with haematoxylin-eosin, PAS for neutral mucins and Alcian blue/high iron diamine for sialomucins/sulphomucins. Morphological changes were grouped into three types modified according to Veress and assessed for dysplasia. RESULTS: Twenty-two patients with an indefinitely diverted pouch were found. The follow-up time after surgery for failure was 10 years. Thirteen patients completed the follow-up. Except for two patients with pelvic/perineal pain, there were no clinical problems. The majority of patients displayed mild to moderate macroscopic signs of inflammation. Morphologically, findings ranged from a preserved mucosal pattern to intense inflammatory reaction. No case of dysplasia or carcinoma was found. CONCLUSION: Most patients with an indefinitely diverted pouch had no complaints regarding the pouch. There was no case of dysplasia. Indefinite diversion may be preferable to pouch excision, especially given the associated morbidity.     

Characteristics of manifest glaucoma at early stages

Intraocular pressures and optic disc hemorrhages were studied in all cases of manifest glaucoma detected in a defined population over a decade. High intraocular pressure was found to be an unreliable signat the detection of a glaucomatous visual field defect and an unusual finding 5–10 yearsbefore. The prevalence of optic disc hemorrhages at the detection of a glaucomatous visual field defect was 33%. All but 9 of 44 persons with manifest glaucoma were found to have had at least one optic disc hemorrhage at one time or another.     

Sublethal effects of tetrachloro-1,2-benzoquinone--a component in bleachery effluents from pulp mills--on vertebral quality and physiological parameters in fourhorn sculpin

The effects of tetrachloro-1,2-benzoquinone (TCQ), a component in bleached kraft mill effluents (BKME), on vertebral and physiological parameters were investigated in juvenile fourhorn sculpin, Myoxocephalus quadricornis L. After about 4.5 months of exposure to 0.1 and 0.5 mg TCQ/liter in 7% salinity brackish water, the fish demonstrated vertebral deformities, aberrant mechanical properties of the vertebrae, effects on white and red blood cell counts, enhanced activity of delta-aminolevulinic acid dehydratase in erythrocytes, and increased levels of ascorbic acid in the liver. The effects are discussed in relation to those previously observed in fish exposed to complex BKME in the field and the laboratory.
