Neutron activation analysis of trace elements in skin

Manganese levels were estimated in skin biopsies and serum in twenty-one cases of psoriasis and fifteen cases of vitiligo. There was a significant reduction in tissue manganese concentrations in psoriasis compared with normal, while vitiliginous skin contained higher manganese levels than apparently normal surrounding skin. Analysis of serum in both conditions revealed no variations in the concentrations of this element. There was no association between manganese content and the degree of melanization in seborrhoeic warts, whereas consistently high levels were found in pigmented moles.     

A Study of Gastric Cancer in Egypt

Since stomach cancer is rare in Egypt, a study was conductedto try to determine the factors responsible for the low incidence.The study included epidemiological and pathological informationon 55 cases of stomach cancer collected from 1970 to 1977, representing0.33% of the admissions for malignancy in this period. Featuresof the Egyptian diet that could be behind the low incidenceare presented.     

Favourable outcome in sclerotherapy for bleeding oesophageal varices in schistosomiasis: Results in 30 patients

Abstract Thirty consecutive patients with bleeding oesophageal varices secondary to schistosomal liver disease received injection sclerotherapy. These formed a part of a prospective study, to evaluate the role of sclerotherapy in the treatment of bleeding oesophageal varices due to different aetiological factors in patients seen at the Gastroenterology Unit, Riyadh Armed Forces Hospital, Saudi Arabia, between December 1980 and July 1984.
Schistosomiasis is endemic in parts of Saudi Arabia. Sclerotherapy has a special place in schistosomal liver disease as liver function is well preserved in this disease. The new antischistosomal drugs are effective and may halt the progress of the disease. However, in many patients portal hypertension with bleeding oesophageal varices is found at diagnosis. Of the patients with schistosomiasis, 63.3% were Group A Child's Classification. Oesophageal varices have been eradicated in 11 cases during the mean follow-up period of 28 months (range 3-44 months). Four patients were referred for surgery because of bleeding gastric varices, two of whom died following operation. One patient, who was also hepatitis B surface antigen positive, died due to re-bleeding from gastric varices. The remaining 25 patients had no recurrence of bleeding and their liver function remained satisfactory.
Surgical procedures for oesophageal varices in schistosomiasis carry the risk of peri-operative and postoperative morbidity and mortality. In contrast, complications following sclerotherapy are minor compared to surgical procedures and none of our patients had any serious sclerotherapy complications.     

ALLERGIC CONTACT DERMATITIS: CLINICAL FEATURES AND PROFILE OF SENSITIZING ALLERGENS IN RIYADH, SAUDI ARABIA

Background. No reports are available on allergic contact dermatitis in Saudi Arabia, although it seems to be a common skin problem. We attempted to explore certain clinical aspects in addition to the profile of sensitizing allergens in our area. As no standard panel for patch testing is available in our geographic region, we examined the suitability of the European Standard Series. Methods. Patch testing was performed on 271 consecutive patients with various forms of dermatitis, referred for evaluation of possible allergic contact dermatitis. The study included 147 women and 124 men. The patients were between 12 and 75 years of age. Results. Out of 271 subjects, 152 (56.1%) showed one or more positive reactions. Of these, 80 (52.6%) were women and 72 (47.4%) were men. Almost one quarter of the patients (25.7%) presented with hand dermatitis. Positive reactions to 21 out of the 22 allergens were found. Sensitization was most common to nickel sulfate (39.5%), potassium dichromate (32.9%), and cobalt chloride (30.9%). Reactions to the other allergens ranged between 14.5% and 1.3%. Less than one percent of the patients (0.66%) reacted to benzocaine and showed no reaction to primin. Conclusions. Allergic contact dermatitis is a common skin problem in Saudi Arabia. Further studies that address the prevalence and incidence of the disease are indicated. The European Standard Series is suitable for patch testing patients in our community; however, we suggest exclusion of benzocaine and primin. The addition of three allergens of local relevance, black seed oil, local perfume mix, and henna, are presented and discussed. The formulation of a regional standard series for patch testing dermatitis patients in our geographic area requires further collaborative studies.     

COMBINATION TAPING TECHNIQUE VERSUS ANKLE FOOT ORTHOSIS ON IMPROVING GAIT PARAMETERS IN SPASTIC CEREBRAL PALSY: A CONTROLLED RANDOMIZED STUDY

BackgroundOne of the important goals in the treatment of spastic cerebral palsy is to maintain efficient and effective walking in order to be independent in activities and participate in society.ObjectiveTo compare the efficacy of foot combination taping of kinesio tape and athletic tape vs ankle foot orthosis in correcting spatiotemporal gait parameters in children with spastic diplegia.MethodsThirty-six children with spastic diplegia were randomly assigned into 3 groups; control, combination taping, and ankle foot orthosis groups. Children in the control group, in addition to those in both experimental groups, continued with conventional physical therapy, 1 h, 3 times per week for 4 weeks. Spatiotemporal gait parameters were assessed with the GAITRite system before and after the application of interventions.ResultsThere were significant increases in walking velocity, step length, stride length, right single support duration, and left single support duration of the ankle foot orthosis and combination taping groups compared with pre-intervention values. Moreover, the post-intervention values of the double support duration of the ankle foot orthosis and combination taping groups were significantly lower than pre-intervention values. There were no significant differences between the post-intervention values of the ankle foot orthosis and combination taping groups for all parameters.ConclusionThe results demonstrated that combination taping is an effective alternative technique to ankle foot orthosis to improve spatiotemporal parameters in children with spastic diplegic in combination with conventional physiotherapy.LAY ABSTRACTChildren with cerebral palsy have abnormal patterns of walking secondary to spasticity, which can negatively affect their functional abilities and quality of life. Several therapeutic interventions are used, with the aim of improving gait quality in those children so that they become independent in functional activities and can participate in society. This study compared the effectiveness of ankle bracing with the application of a combination taping on gait parameters. The results showed that both interventions are equally effective. Combination taping might be considered a promising alterative to ankle joint bracing, as it is a more functional and less aggressive technique.Key words: combination taping, ankle foot orthosis, gait parameters, cerebral palsy

Cerebral palsy (CP) is a lifelong motor impairment caused by an early brain injury. Depending on the dominant neurological signs of children with CP, the condition is classified as spastic, ataxic, athetoid, or flaccid (1). More than 70% of children with CP are spastic (2). Gait in children with spastic CP is frequently associated with abnormal gait kinematics, linked to increased walking energy cost, which may lead to activity limitations (3).Plantar flexion in the ankle at the beginning of standing and in all phases of walking is one1 of the most common dynamic musculoskeletal deformities in children with spastic CP, which could be accompanied by additional abnormal joint positions of the lower extremities (4). The ability to maintain proper joint alignment of the lower extremity, and monitor the position of the foot while standing and walking, are critical prerequisites for gait in children with CP (5).Lower extremity orthosis, such as ankle foot orthosis (AFO) is widely recommended in children with spastic CP to prevent the progression of the deformity and to improve the child’s gait efficiency (6). The solid AFO maximizes control by restricting both plantarflexion and dorsiflexion movements in the stance and swing phases. Its rigid structure prevents ankle rocker function and reduces excessive plantarflexion during the stance phase, thus facilitating clearance of the toes during the swing phase (7). The benefits of wearing an AFO on gait parameters in children with spastic CP have already been documented in the literature (8).Athletic and Kinesio tapes are the 2 most common types of tape used in clinical settings. Both can be used on patients with orthopaedic or neurological dysfunctions. Athletic tape is a rigid/inelastic tape that restricts movement, while Kinesio tape is a form of flexible/elastic tape. Researchers have used them for similar purposes, such as spasticity control, muscle function facilitation, and joint stabilization (9). Furthermore, studies suggest that rigid tape is more effective than elastic tape at controlling joint mobility (10).The use of Kinesio taping in paediatric rehabilitation has become increasingly popular in recent years. Recent systematic reviews reported moderate evidence that Kinesiology taping is a valuable complement to physiotherapy treatment in better-performing children with CP (11, 12). Combination taping is a technique first introduced by Kenzo et al. (13), in which Kinesio tape is combined with rigid athletic tape to maximize the treatment benefits. This approach remains briefly addressed in the literature with no prior studies has examined the effects of combination tapings of Kinesio tape and athletic tape in the CP paediatric population. Hence, this study was conducted to compare the effectiveness of foot combined taping vs AFO in correcting spatiotemporal gait parameters in spastic CP children with equinus deformity.
