Lepidoptera is a large order of insects, with more than 180,000 species word-wide, showing larval stages of butterflies and moths known as wormlike caterpillars. Almost 12 families of butterflies around the world are capable of causing severe human injuries, varying from dermatitis, renal failure, hemostatic alterations, respiratory failure and neurotoxic symptoms. These caterpillars are coated in long, hair-like setae containing venom to protect themselves against aggressive predators. The setae cause a painful reaction, upon contact, due to presence of neurotoxins. These caterpillars are extensively dispersed all through North America and often, during the dry and wet seasons in tropical regions, being able to sustain two annual larval generations. There exist several species of Megalopyge caterpillars; however, Megalopyge opercularis is the most widely distributed species in Latin America and the United States. This work reports, to our knowledge, the first case of envenomation by the "gusano-pollo" (Megalopyge opercularis), a stinging caterpillar, described in Venezuela. The patient in this report presented severe symptoms, including systemic reactions such as intense hand pain irradiated to the upper arm, restricted swelling, headache, dizziness, serious chest distress and shock-like symptoms that required hospitalization. Symptoms improved upon treatment with opiaceous analgesic drugs.

Sonographers have a high risk of musculoskeletal disorders. This study explores the associations between working conditions and musculoskeletal pain based on the frequency and intensity of pain in the neck and upper extremities. A questionnaire was answered by 291 female sonographers. High prevalence of neck/shoulder pain was associated with eye complaints and headache related to work on the computer, dissatisfaction with the computer workstation, high mechanical exposure index (MEI) and high demands. The possibility to adjust the keyboard and chair, and adequately corrected eyesight were positive factors. High prevalence of elbow/hand pain was associated with performing echocardiography, computer-related eye complaints, high MEI and high job and sensory demands. In echocardiography, working with a straight wrist and holding the transducer with a two-handed grip or alternating hands was associated with a low prevalence of elbow/hand pain. Thus, further improvements in the working conditions are possible and are recommended.

While thrombotic microangiopathy (TMA) can commonly affect the kidney, peripheral nerve involvement has not been reported to date. A 56-year-old man, recipient of a kidney allograft, reported severe headaches, tremors, and diarrhea followed by sudden-onset right foot drop after increasing his dose of tacrolimus. He then developed acute right hand pain, numbness, and weakness. At presentation, neurological examination and electroneuromyography confirmed the presence of right worse than left, sciatic and ulnar mononeuropathies. Kidney biopsy showed evidence of a thrombotic microangiopathy. Similarly, nerve biopsy showed thrombosis of epineurial blood vessels with minimal inflammation. Herein, we demonstrated that thrombotic microangiopathy can involve the peripheral nerves, resulting in major morbidity. Distinguishing TMA from vasculitis is important because it has major treatment implications.

Objective: Regional disparities in health services is a crucial problem in Cambodia. Particularly, a number of NCD risk factors are more common among the rural poor. Fortunately, 80% of NCDs are preventable and cost-effective interventions exist. Therefore, health care needs assessments regarding NCDs in poor rural areas are vital. The object of this pilot study was to identify health care needs regarding NCDs among residents in poor rural areas in Cambodia. Materials and Methods: A medical health check-up and questionnaire survey were conducted with 208 rural residents who participated in a free health check-up and doctor consultation in Kaoh Peam Reang. Results: One hundred sixteen (55.8%) females were included in the total sample size of 208 participants; the majority (52.9%) were between 35 and 65 years of age. Twenty-five participants (12%) were current smokers, and 44 (21%) were current alcohol drinkers. Eighty (38.5%) participants had hypertension and 44 participants (21.2%) had a body mass index over 25. Alcohol drinking and smoking habits were more common among men. The five most frequent medical complaints were headache (18.3%), lower back pain (14.4%), foot and hand pain (13.9%), joint pain (10.1%), and difficulty breathing (10.1%). Conclusions: The medical need for doctor consultations regarding chronic disease and chronic pain might be higher in poor rural areas in Cambodia.
