Objective: To compare the clinical effects of two different skin preparation methods for infant craniocerebral surgery. Methods: Totally 120 infants who were going to receive craniocerebral surgery were divided into two groups by random number table, 60 cases in the observation group and 60 cases in the control group. The scalp of both groups was cleaned with moisturizing oil every day from 3 days before operation. On 1 day before operation, the observation group used electric shaver to shave off all hair on the head, and then rinsed with warm water. The control group was treated with skin preparation knife to shave all the hair under soap water lubrication and rinse with warm water. The skin injury rate, incision infection rate and pain score of the two groups were evaluated. Results: The incidence of skin injury and incision infection were 0 and 1.7% (1/60) in the observation group, 18.3% (11/60) and 13.3% (8/60) in the control group, respectively. There were significant differences between the two groups (χ²= 12.110, 5.886, all P < 0.01 or 0.05). The median score of pain in the observation group was 0 (Q₁:0, Q₃:0), while 1.5 (Q₁:1, Q₃:2) in the control group, and there were significant differences between the two groups (Z= 3.286, P < 0.01). Conclusion Electric shaver is superior to skin preparation knife in shaving hair of infants. It not only reduces the incidence of head skin injury, incision infection and pain in the process of skin preparation, but also reduces the incidence of incision infection after craniocerebral surgery in infants. It is worth popularizing.

Acute suppurative thyroiditis(AST) is a rare thyroid disease, mostly caused by infections such as Staphylococcus aureus, and it is difficult to distinguish from subacute thyroiditis(SAT) at the beginning of the disease. Here we report the clinical data of a young male patient who was initially misdiagnosed as SAT, but was clinically diagnosed as AST with DNSIs accompanied by LS. The clinical features and treatment, combined with related literature, aim to enhance clinicians' understanding of this disease.
