We previously described two unrelated patients showing characteristic facial and skeletal features, overlapping with the kyphoscoliosis type Ehlers-Danlos syndrome (EDS) but without lysyl hydroxylase deficiency [Kosho et al. (2005) Am J Med Genet Part A 138A:282-287]. After observations of them over time and encounter with four additional unrelated patients, we have concluded that they represent a new clinically recognizable type of EDS with distinct craniofacial characteristics, multiple congenital contractures, progressive joint and skin laxity, and multisystem fragility-related manifestations. The patients exhibited strikingly similar features according to their age: craniofacial, large fontanelle, hypertelorism, short and downslanting palpebral fissures, blue sclerae, short nose with hypoplastic columella, low-set and rotated ears, high palate, long philtrum, thin vermilion of the upper lip, small mouth, and micro-retrognathia in infancy; slender and asymmetric face with protruding jaw from adolescence; skeletal, congenital contractures of fingers, wrists, and hips, and talipes equinovarus with anomalous insertions of flexor muscles; progressive joint laxity with recurrent dislocations; slender and/or cylindrical fingers and progressive talipes valgus and cavum or planus, with diaphyseal narrowing of phalanges, metacarpals, and metatarsals; pectus deformities; scoliosis or kyphoscoliosis with decreased physiological curvatures of thoracic spines and tall vertebrae; cutaneous, progressive hyperextensibility, bruisability, and fragility with atrophic scars; fine palmar creases in childhood to acrogeria-like prominent wrinkles in adulthood, recurrent subcutaneous infections with fistula formation; cardiovascular, cardiac valve abnormalities, recurrent large subcutaneous hematomas from childhood; gastrointestinal, constipation, diverticula perforation; respiratory, (hemo)pneumothorax; and ophthalmological, strabismus, glaucoma, refractive errors.

Purpose To investigate control mechanisms for ocular blood flow changes after dynamic exercise using two different methods. Methods Changes over time in the tissue blood flow in the retina and choroid-retina of healthy volunteers were determined after dynamic exercise (Master's double two-step test), using scanning laser Doppler flowmetry (SLDF) and laser speckle flowgraphy (LSFG). Changes in intraocular pressure (IOP), blood pressure, plasma CO 2 gas concentration (pCO 2 ), and levels of nitric oxide (NO) metabolites were examined.Results Retinal blood flow measured by SLDF increased significantly only at 15 min after exercise. In contrast, normalized blur (NB) values in the choroid-retina, obtained by LSFG, increased significantly up to 60 min after exercise. Ocular perfusion pressure (OPP), calculated from IOP and blood pressure, increased significantly immediately and 15 min after exercise. The plasma NO metabolite levels increased significantly, although pCO 2 levels were unchanged. Conclusions Dynamic exercise changes OPP and produces increased tissue blood flow in the retina in the immediate postexercise period, while blood flow increases more persistently in the choroid-retina. Difference in control of blood flow in these two regions may be related to stronger autoregulatory mechanism of blood flow in the retina. Nitric oxide may play a role in the regulation of blood flow.

Antibiotic treatment was effective in a considerable number of ulcerative colitis patients whose PDAI score was less than 7 after IPAA.

We report on a case of an infected urachal remnant successfully treated via a single-incisional laparoscopic technique. An 18-year-old woman was diagnosed with an infected urachal remnant. The center of the umbilicus was pulled and inverted from the skin, and the cephalic side of the urachus was dissected from the umbilicus. A single-incision laparoscopic technique employing ultrasonic coagulating shears was used to dissect the urachal remnant from the stump of the umbilicus to the caudal end. Single-incision laparoscopic excision of the urachal remnant can be used successfully as a minimally invasive technique with optimal cosmetic outcomes.
