An anomaly in cheliceral dentition of the fixed finger is recorded in the scorpion Scorpio kruglovi Birula, 1910. This rare teratological anomaly herein is described and illustrated

A new case of pedipalp regeneration in \u3ci\u3eScorpio kruglovi\u3c/i\u3e Birula, 1910 (Scorpiones: Scorpionidae)

A new case of pedipalp regeneration is described and illustrated in a subadult female of Scorpio kruglovi Birula, 1910. A small, regenerated part of chela is observed on the anterior aspect of a normally developed right patella. This is the second published case of pedipalp regeneration

A reliable method for treatment of nonhealing ulcers in the hindfoot and midfoot region in diabetic patients: Reconstruction with abductor digiti minimi muscle flap

The foot has a unique anatomic composition and a perfect architecture, which is necessary for mobilization. However, this complex structure is also responsible for healing problems in foot reconstruction. After 25 years of experience in diabetic foot surgery practice, we observed that some hindfoot ulcers are like an iceberg in that they have much more involvement in the plantar fat pad than the skin, and the lateral midfoot region is a common site for ulcer formation. Also the fifth tarsometatarsal joint region is a prominent anatomic structure vulnerable to repetitive trauma and ulcer formation that may easily spread to other parts of the foot. These ulcers should be reconstructed with well-vascularized tissues such as muscle flaps after debridement. Between 2003 and 2010, 17 diabetic patients with foot ulcers, involving bone and joint, were reconstructed with abductor digiti minimi muscle flap. When it is needed, the flap is covered with a small split-thickness skin graft. In all cases, complete healing was achieved. The muscle flap functioned well as a versatile and shock absorbent coverage without recurrence of the ulcer during a mean follow-up period of around 2 years. Diabetic foot ulcers should be evaluated and treated individually depending on their location and affected tissue composition. The most appropriate reconstructive option should be selected for each lesion. The abductor digiti minimi muscle flap is extremely useful for the reconstruction of small-to moderate-sized defects that have exposed bone, joint, or tendons in the hindfoot and lateral plantar midfoot.

PCR analysis of Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola and Fusorbacterium nucleatum in middle ear effusion

Anaerobes contribute to the severity and chronicity of infections that occur in and around the oral cavity. One of the factors involved in the pathogenesis of otitis media with effusion (OME) is the retrograde movement of bacteria from the oropharynx into the middle ear cavity. OME is one of the most common causes of hearing loss in children. We have used a PCR-based method to identify Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola and Fusobacterium nucleatum in 65 middle ear effusion (MEE) samples obtained from paediatric patients seen for myringotomy and tube placement. DNA was extracted from MEE samples and PCR was initially done with DNA extracts by using the universal primers within the 16S rRNA gene sequence common to all bacterial species. The positive samples were further assessed with four species-specific primers. With the universal primers, 27 of 65 samples (41.5%) showed positive reaction indicating the presence of bacterial DNA. F. nucleatum was present in 10 out of 27 PCR-positive samples (37%) while one sample was positive for both T. denticola and F. nucleatum (3.7%). A. actinomycetemcomitans and P. gingivalis were not detected in any of the samples. The results of this study suggest that oral bacterial species may also play a role in the aetiopathogenesis of paediatric MEE. (C) 2001 Academic Press
