Notalgia paresthetica is a sensory neuropathy involving the dorsal spinal nerves. The characteristic symptom is pruritus on the back, occasionally accompanied by pain, paresthesia, and/or hyperesthesia, which results in a well-circumscribed hyperpigmented patch in the symptomatic area. The etiology of this condition has not yet been completely defined. ⋯ The striking correlation of notalgia paresthetica localization with degenerative changes in the spine suggests that spinal nerve impingement may contribute to the pathogenesis of this entity.

Cutaneous myiasis (CM) due to Diptera fly larvae shows different patterns in different regions. Many modalities of treatment have been described. The objectives of our study were to identify the species causing CM in Sri Lanka, the common sites of infestation, and the contributory factors, and to assess some treatment modalities, in particular mineral turpentine and certain herbal preparations. ⋯ All cases of CM were due to larvae of Chrysomya species. The commonest was C. bezziana. C. megacephala larvae causing CM have been reported for the first time in Sri Lanka. The foot was the site of predilection. Dermatitis, psychiatric illness, leprosy, diabetes, and mental subnormality were some contributory factors. Topically instilled mineral turpentine, followed by manual removal of maggots, was effective in most cases. The plant extracts tested in vitro were ineffective. As C. bezziana is an obligatory parasite capable of penetrating deeply, the importance of preventive measures is emphasized.

Pseudomonas aeruginosa folliculitis (PF) can develop after exposure to contaminated water in heated swimming pools, whirlpools, and hot-tubes, or after diving suit dressing. ⋯ Based on our experience, we suggest that shower/bath exposure should be definitively included amongst the possible pathogenic events causing PF. Pseudomonas aeruginosa is responsible for a number of clinical pictures, e.g. otitis externa, conjunctivitis, toe web intertrigo, green nail syndrome, infection of burns and wounds, and folliculitis. Pseudomonas aeruginosa folliculitis (PF) has been reported to develop as a consequence of exposure to contaminated water in heated swimming pools, whirlpools, and hot-tubes, or related to diving suits and leg waxing.1-4 We observed 14 cases of PF after shower/bath exposure. This is probably an underestimated pathogenic event; to our knowledge, only one case has been reported to date.5 In our patients, the clinical expression of dermatitis was constant, PF being a clinically well recognizable skin condition.
