As part of on-going efforts to use eco-friendly alternatives to chemical pesticides, methanol crude extracts of Plectranthus glandulosus and Callistemon rigidus leaves were sequentially fractionated in hexane, chloroform, ethyl acetate, and methanol to establish the most active fraction(s) against Callosobruchus maculatus in cowpea. Cowpea seeds (25 g) were treated with 0.5, 1, 2, and 4 g/kg of...

Introduction. The purpose of this study was to determine the interand intra-observer reliability of a clinical radiographic scale for hallux rigidus. Methods. A total of 80 patients were retrospectively selected from the patient population of two foot and ankle orthopaedic surgeons. Each corresponding series of radiographic images (weightbearing anteroposterior, weight-bearing lateral, and obli...

Surgical techniques for the treatment of hallux rigidus have evolved during the past decade. Previously, main treatments were cheilectomy for earlier stages of hallux rigidus and resection arthroplasty or arthrodesis for advanced stages. Although arthrodesis has been considered the ‘‘gold standard’’ for advanced hallux rigidus, in younger and more active patients, activity, functional, and shoe...

Tropical hyperseasonal savannas provide a rare example of a tropical climax community dominated by graminoid species. Species living in such savannas are frequently exposed to excess heat and light, in addition to drought and waterlogging, and must possess traits to avoid or tolerate these stress factors. Here we examine the contrasting heat and light stress adaptations of two dominant savanna ...

Surgery for the management of hallux rigidus aims to relieve pain and improve function. Arthrodesis, though reliable in terms of pain relief may encounter some resistance from patients reluctant to have a fusion. Results of other techniques, such as silastic implants, may give poor long-term results. Excisional arthroplasty and cheilectomy are also routinely used. Interposition arthroplasty has...

An estimated 40% of the US population have foot problems.Of all patients aged over 50 years, 2.5% report degenerative arthritis of the first metatarsophalangeal (MTP) joint, termed 'hallux rigidus'. First MTP osteoarthritis is the most common arthritic condition in the foot.Progression of great toe arthritis is associated with pain and loss of motion. Non-surgical intervention begins with shoe ...

Hallux rigidus and hallux valgus are challenging clinical entities and represent a particularly difficult dilemma when presenting simultaneously. There is no consensus among surgeons as to a surgical correction for the concomitant treatment of both diagnoses. In this article, we present a case involving a young, active patient with hallux valgus and hallux rigidus who underwent surgical correct...

Hallux rigidus occurs in 10% of persons aged 20 to 34 years but in as much as 44% of people older than 80 years. Surgical intervention has been suggested for cases of hallux rigidus that have failed using conservative methods. The modified cheilectomy is considered by many the first-line treatment for this disease, given the procedure's inherent ability to eliminate degenerate bone and cartilag...
