RESUMO
A 34-year-old man presented with a 3-month history of intense itching of the pubic area, which had been diagnosed previously as dermatitis and treated unsuccessfully with topical steroids. Under dermoscopy examination, the typical broad body of a pubic louse, grasping on to several hairs with its large middle and hind legs like a gymnast, a finding that cannot be seen with clinical examination alone. Many small oval nits were also seen on the hair. Microscopy examination demonstrated the internal structure of lice and nits. We diagnosed the patient as having pubic lice.

Transmission of the crab louse Phthirus pubis generally occurs by close body contact. Diagnosis is usually clinical and screening for other sexually transmitted infections (STIs) is indicated. While most evidence is extrapolated from studies of head lice treatments, topical pediculicides are recommended and treatment of sexual contacts is indicated.

BACKGROUND: It is not mandatory to report Pediculosis capitis and Phthirus pubis in most countries; therefore, little is known about the seasonality of these infestations. METHODS: We analysed the data based on routine and mandatory reporting of every case of Pediculosis capitis and Phthirus pubis to the Army Health Branch Epidemiology Department, Israel, over the last two decades. RESULTS: The average 20-year incidence of Pediculosis capitis shows a significant rise during the warmer months (R2 = 0.692, P < 0.05) with a parallel significant decrease in the cooler months (R2 = 0.893, P < 0.05). The results for Phthirus pubis show a significantly higher person-time incidence in the winter (P < 0.001). Sensitivity analysis to investigate possible sources of heterogeneity during this time indicated that no single year was an important source of heterogeneity. CONCLUSIONS: Pediculosis capitis is more frequent in the warmer months, whereas Phthirus pubis is more dominant in the cooler months.

Studies in Cameroon and Burkina Faso examined the invasion process of cattle by adult Amblyomma variegatum Fabricius (Acari: Ixodidae) ticks. Nearly all the ticks picked up in the pasture during grazing were found on the limb ends, near the hooves, where they temporarily attached. Then when the cattle lay down, the ticks moved from the feet towards the predilection sites, where they attached definitively. Many ticks disappeared during this displacement. All the female ticks and approximately 70% of the males were thus unable to attach to the predilection sites as long as the pioneer males had not attached and started to produce attraction-aggregation-attachment pheromones. Nevertheless, A. variegatum females and males attached to the feet in similar numbers during grazing, whether the cattle were already infested or not, indicating that stimuli originating from the hosts are powerful enough to attract both sexes. After attachment of the pioneer males, the number of ticks that successfully reached the predilection sites increased. However, even on infested animals, 40-50% of A. variegatum ticks found near the hooves after the grazing periods disappeared during the night following their capture. When moving from the temporary attachment sites towards the final ones, one-third of the ticks changed the individual host. Considering this two-stage infestation process, it is suggested that a targeted tick control, using a foot-bath, might greatly reduce cattle infestation. In particular, it could be effective in traditional herds, with animals grazing permanently during the day, lying down only once back in the night pen.

Gravid adult female worms of Wuchereria bancrofti were observed in fine needle aspirates of soft tissue swellings from three patients. An inguinal lymph node was aspirated in two cases, and a breast nodule was the site of aspiration in the third case. In one of the inguinal lymph node aspirates, two adult gravid female worms were identified.
