Background: Once the year comes to end, around late November up to February, there prevails the dry cold wind originated from the Sahara Desert in North Africa toward the West African countries called Harmattan. The Harmattan season has adverse effects on human health and comfort. There is a wide spread of airborne diseases coupled with the dryness of human skin. Small children are mostly dehydrated. Aim and Objectives: This study focused on the impacts of the Harmattan season in Keffi town, Nasarawa state, Nigeria, on human health. Materials and Methods: The use of correlation and regression analysis is employed to analyse the data. It also involved the collection of data from the Nigerian Meteorological Agency. The field survey also confined about 100 respondents. Result: The results indicate a positive correlation between the Harmattan and its impact on human health, with about 0.64. The climate and anthropogenic factors are mostly the responsible factors influencing the high prevalence of Harmattan. Conclusion: Nevertheless, there is the good side of the Harmattan season, such as the lowering of environmental temperature and some crops enjoy the cold season.

Objectives: The objective of the study was to discuss the influence of the intervention program of strength training on the hidden obese college students on the basis of aerobics movement. Methods: By means of the voluntary principle, 28 college students with invisibility obesity were selected from the test instruments, such as height and weight, and they were randomly divided into observation group and control group, each of which was 14. The control group adopted a routine training program, and the observation group adopted aerobics and strength training intervention program for 6 weeks. Moreover, the physical form, physical quality, and so on of the two groups of invisible obese college social workers were observed. Results: The body composition, skinfold thickness, strength, and flexibility of college students were significantly better than those in the control group. Compared with before training, the improvement effect is very obvious, and the difference is significant (P < 0.05). However, in the body circumference and the lung activity, the improvement was not obvious (P > 0.05). Conclusions: Aerobics combined with strength training intervention can improve the body composition of invisible obese college students, improve strength and muscle content, and can improve flexibility. Moreover, the impact is very obvious.

Organophosphate pesticides are used in agriculture to protect plants and livestock from pests so as to increase food yield. They are also used to control household and structural pests. Organophosphate pesticides inhibit acetylcholinesterase, preventing the break-down of acetylcholine in the nervous system which leads to the accumulation of acetylcholine in nerve endings resulting in paralysis. Information on organophosphate pesticides, mechanism of action of organophosphate chemicals, organophosphate toxicity, biological monitoring, and regulation of pesticides was obtained from other published articles, textbooks, and relevant internet sites. Studies have shown that there is a link between sensorimotor and cognitive impairments to organophosphate exposure as well as a link between affective disorders, depression, and suicide to the acute and chronic exposure to organophosphate insecticides in humans. Although being used as a pesticide and an insecticide, organophosphate chemicals pose a huge danger to health and as such, there should be general public awareness on its health risk with continuous and unguarded exposure to it.

Background: Ankle pain is a disabling clinical complaint with substantial negative impact on patients' quality of life. The etiology of foot/ankle pain is multifactorial. Despite careful and detailed clinical history and accurate physical examination, reaching an accurate diagnosis is often difficult because nontraumatic ankle pain has a broad-spectrum etiology. Imaging plays a vital role in the etiology of ankle pain. Materials and Methods: This was a prospective study done in collaboration between department of orthopedics and radiodiagnosis and imaging on 43 patients from August 2018 to December 2019. Plain radiography of the ankle joint with anteroposterior and lateral views was done in every patient. Further investigations were advised using the American College of Radiology Appropriateness criteria scale for chronic ankle pain. Results: The most common causes of nontraumatic ankle pain were tendinosis of Achilles 6 (13.9%) including calcific tendinitis, tenosynovitis of other tendons 4 (9.3%), and benign bone tumors 4 (9.3%). Overall imaging was able to pick probable etiology in 34 out of 43 patients. No possible cause could be found in nine cases. Conclusion: Radiological imaging, especially cross-sectional imaging, is an asset for diagnosing etiology of ankle pain. Orthopedicians should not hesitate in referring patients with ankle pain to the radiology department.

Objectives: The objective of this study is to explore the effects of different exercise patterns on the body composition of female students with recessive obesity. Methods: According to the principle of knowledge and voluntariness, 136 female students who volunteered to participate in the investigation were selected as the research object. The IOI 353 analyzer was used to screen out 48 college students with invisibility obesity, which was averagely divided into the nonexercise group, the aerobic exercise group, the resistance training group, and the aerobic resistance group. The nonexercise group did not take any exercise, and the other groups performed 12 weeks of exercise. Before exercise, 4 weeks, 8 weeks, and 12 weeks after the exercise, each body component was detected. Results: Compared with those before the intervention, the body fat percentage (BF%) and waist-to-hip ratio (WHR) of the aerobic exercise group, the resistance training group, and the aerobic resistance group were significantly decreased. In addition, the body mass index (BMI) of the aerobic exercise group was significantly decreased, and the difference was statistically significant (P < 0.05). As compared to the control group, the BF% and WHR of the aerobic exercise group, the resistance training group, and the aerobic resistance group were better than that of the control group. Moreover, BMI in the aerobic exercise group was significantly better than that in the control group, and the difference was statistically significant (P < 0.05). Conclusions: The exercise has obvious improvement effect on the body composition of the invisible obese female college student body, which can reduce the body fat rate and improve the morphology. The different modes of movement also have an influence on their body composition, and the exercise mode can be selected reasonably in combination with their own situation.

A 10-year-old male presented with a history of swelling in the left eye for the past 4 days. He was already on antibiotics, but his symptoms did not improve. Ocular examination revealed stone pieces/fragments lodged in the left eye. This case highlights a rare mimic of probable diagnosed orbital cellulitis.

Objectives: This study aimed to study the effect of exercise intervention under energy metabolism on obesity in obese college students and to analyze the body of obese college students. Methods: Fifty-six obese college students were selected as the study subjects and randomly divided into control group and observation group. In the control group, 28 cases were treated with a routine exercise intervention, while 28 cases in the observation group were treated with exercise intervention based on the energy metabolism, and the fat degree, fat content, and muscle weight of the two groups were observed and recorded. Results: Compared with the control group, the obesity degree of the observation group was significantly lower, and there was a significant difference between the two groups (P < 0.05). Compared with the observation group, the fat content in the control group was relatively high, and there was a significant difference between the two groups (P < 0.05). The growth rate of muscle in the observation group was obviously higher than that of the control group, and there was a significant difference between the two groups (P < 0.05). Conclusions: The application of exercise intervention under energy metabolism to the obesity of obese college students could effectively increase the muscle weight of college students and reduce the fat content and fat degree.
