Blue light has been widely used for the treatment of neonatal hyperbilirubinemia since the 1950s. Neonatal phototherapy can decrease plasma unconjugated bilirubin level, thus preventing bilirubin encephalopathy, and greatly reduces the exchange transfusion rate. Generally, it is accepted that the side effects of neonatal phototherapy are not serious and seem to be well controlled, however recent research has provided new evidence. The short-term side effects of phototherapy include interference with maternal-infant interaction, imbalance of thermal environment and water loss, electrolyte disturbance, bronze baby syndrome and circadian rhythm disorder. In addition, phototherapy may be associated with some long-term side effects such as melanocytic nevi and skin cancer, allergic diseases, patent ductus arteriosus and retinal damage. Therefore, it is necessary to develop evidence-based guidelines, new light devices and alternative agents, as well as individualized treatments, to minimize the side effects of phototherapy.

OBJECTIVETo study the effect and safety of intensive phototherapy in the treatment of neonatal hyperbilirubinemia.

METHODSA total of 144 neonates with neonatal hyperbilirubinemia were randomly and prospectively divided into intensive phototherapy group and conventional phototherapy group, with 72 neonates in each group. The therapeutic effect and incidence of complications were compared between the two groups.

RESULTSWithin 12 hours after phototherapy, the total serum bilirubin level in the intensive phototherapy group was significantly lower than in the conventional phototherapy group (P<0.05), and the intensive phototherapy group had a significantly greater reduction in serum bilirubin level than the conventional phototherapy group (P<0.05). The intensives phototherapy group had a significantly shorter time of phototherapy than the conventional phototherapy group (P<0.05). The incidence rates of fever, diarrhea, rash, and hypocalcemia and reductions in blood calcium and hemoglobin levels after phototherapy showed no significant differences between the two groups.

CONCLUSIONSDuring the initial stage of phototherapy, intensive phototherapy can quickly and effectively reduce the serum level of bilirubin in neonates with neonatal hyperbilirubinemia. It can also shorten the total phototherapy time, and does not increase the incidence of adverse events. Therefore, it is superior to conventional phototherapy.

We report a case of corneal deposition of pigments from cosmetic contact lenses after intense pulsed-light (IPL) therapy. A 30-year-old female visited our outpatient clinic with ocular pain and epiphora in both eyes; these symptoms developed soon after she had undergone facial IPL treatment. She was wearing cosmetic contact lenses throughout the IPL procedure. At presentation, her uncorrected visual acuity was 2/20 in both eyes, and the slit-lamp examination revealed deposition of the color pigment of the cosmetic contact lens onto the corneal epithelium. We scraped the corneal epithelium along with the deposited pigments using a no. 15 blade; seven days after the procedure, the corneal epithelium had healed without any complications. This case highlights the importance of considering the possibility of ocular complications during IPL treatment, particularly in individuals using contact lenses. To prevent ocular damage, IPL procedures should be performed only after removing the lenses and applying eyeshields.

OBJECTIVETo assess the efficacy and safety of external application of Chinese herbal drugs (ex-CHD) in the treatment of psoriasis.

METHODSLiterature regarding randomized clinical trials (RCTs) of psoriasis treatments with ex-CHD, either alone or combined with Western medicine (WM) or physiotherapy, controlled by untreated, placebo or WM treatment were found in electronic databases, including PubMed/MEDLINE, EMBASE, Cochrane Library, Cochrane Central Register of Controlled Trials, China Biology Medicine Disc (CBM), Chinese National Knowledge Infrastructure (CNKI), Wanfang database and VIP database from their inception through July 2011. Study selection, data extraction, quality assessment, and data analyses were conducted according to the Cochrane standards.

RESULTSA total of 10 randomized trials (involving 1,435 patients) were included. Because both test and control drugs used in the RCTs were different from each other, the effects can only be described singly and calculated. Regarding the total effective rate for the treatment of psoriasis, ex-CHD in combination with ultraviolet radiation b (UVB) or narrow band ultraviolet radiation b (NB-UVB), which was reported in 6 trials, was superior to UVB alone. One study reported that ex-CHD and externally applied WM had equivalent effects. In another study, ex-CHD showed better results than placebo. However, another two comparisons of ex-CHD and WM (all in combining with oral WM) showed uncertain outcomes. Nine trials reported adverse reactions. Of these, 7 RCTs included statistical analysis. The results showed that the side-effects that occurred in ex-CHD combined with UVB were less severe than those caused by UVB alone, but the incidence was roughly the same as WM.

CONCLUSIONThe evidence supporting the efficacy of ex-CHD with respect to treating psoriasis is quite limited and must be strengthened by high-quality studies.

BACKGROUND: Intensive phototherapy (IPT) and exchange transfusion (ET) are the main treatments for extreme hyperbilirubinemia. However, there is no reliable evidence on determining the thresholds for these treatments. This multicenter study compared the effectiveness and complications of IPT and ET in the treatment of extreme hyperbilirubinemia. METHODS: This retrospective cohort study was conducted in seven centers from January 2015 to January 2018. Patients with extreme hyperbilirubinemia that met the criteria of ET were included. Patients were divided into three subgroups (low-, medium-, and high- risk) according to gestational week and risk factors. Propensity score matching (PSM) was performed to balance the data before treatment. Study outcomes included the development of bilirubin encephalopathy, duration of hospitalization, expenses, and complications. Mortality, auditory complications, seizures, enamel dysplasia, ocular motility disorders, athetosis, motor, and language development were evaluated during follow-up at age of 3 years. RESULTS: A total of 1164 patients were included in this study. After PSM, 296 patients in the IPT only group and 296 patients in the IPT plus ET group were further divided into the low-, medium-, and high-risk subgroups with 188, 364, and 40 matched patients, respectively. No significant differences were found between the IPT only and IPT plus ET groups in terms of morbidity, complications, and sequelae. Hospitalization duration and expenses were lower in the low- and medium-risk subgroups in the IPT only group. CONCLUSIONS In this study, our results suggest that IPT is a safe and effective treatment for extreme hyperbilirubinemia. The indication of ET for patients with hyperbilirubinemia could be stricter. However, it is necessary to have a contingency plan for emergency ET as soon as IPT is commenced especially for infants with risk factors. If IPT can be guaranteed and proved to be therapeutic, ET should be avoided as much as possible.

OBJECTIVETo observe the effect of intense pulsed light (IPL) on transforming growth factor-beta1 mRNA (TGF-beta1 mRNA) expression in rat skin and explore the molecular mechanisms of photorejuvenation.

METHODSFifteen SD rats were exposed to IPL in 3 dermal regions with triple pulses (duration of 4, 5, and 6 ms) at the energy density of 34 J/cm2 and pulse delay of 20 or 25 ms. On days 1, 3, 5, 7, 15, and 30 after the treatment, skin specimens from the treated and non-treated areas were obtained to detect TGF-beta1 mRNA expression with in situ hybridization.

RESULTSIn the UPL-exposed skin areas, TGF-beta1 mRNA expression was detected in the epidermal keratinocytes and dermal cells 1 day after the exposure, reaching the highest expression level on day 7 followed by gradual decrement since day 15, and till day 30, only weak expression was found in the dermal cells. In the non-exposed regions, the cells remained negative for TGF-beta1 mRNA.

CONCLUSIONIPL can enhance TGF-beta1 mRNA expression in the skin, suggesting that TGF-beta1 plays an important role in dermal remodeling in photorejuvenation.

OBJECTIVETo investigate the application of intense pulsed light (IPL) depilation in the auricular reconstruction with totally expanded skin and its suitable parameter.

METHODSFrom February 2009 to September 2013, one tissue expander(100 or 150 milliliters) were implanted under the skin of mastoid in 126 patients who suffered from microtia. During the skin expanding, the hair on the expanded skin was depilated by JPL technique. The parameter, operation, interval, the depilation result and the complication were recorded. The autologous rib cartilage frameworks were implanted in the second phase of auricular reconstruction.

RESULTSThe energy of IPL was 20 - 35 J/cm2 (mean 25. 3 J/cm2), the width of pulse was 26 - 30 ms ( mean 27. 9 ms), the interval between two operations was 4 weeks. Ninety-six patients were cured(76. 2%, 96/126). The total depilation efficient is 96. 8% (122/126). A fine banding blisters was found in one patient whose depilation areas was marked by black pen. Skin erythema was found in five patients and skin pigmentation was found in 7 patients. There were no skin necrosis and expander exposure in all patients. During 6 - 12 months of follow-up period, ninety-two patients were cured (73.0%, 92/126) and the total depilation efficient is 92. 9% (117/126).

CONCLUSIONSIPL depilation during the skin expanding is feasible and safe with careful procedure. The hairless expanded skin is enough to cover the framework, as well as the post-auricular area. The appearance of reconstructed ear is better without hair.

Foot ulcers increase morbidity and mortality in diabetic patients. Due to poor healing factors, surgical wound healing is questionable in diabetic patients. We report a patient with insulin-dependent diabetes mellitus, sensory neuropathy and microangiopathy, who had an infected stump of the right three middle digits and subsequent transmetatarsal amputation. The infected postoperative ulcer was treated with complex phototherapy, including laser and ultraviolet C (UVC) radiations. A total of 23 sessions of low-intensity laser therapy and UVC irradiation were administered over a five-week period. The infected surgical wound healed completely. During the three-month follow-up period, there was no recurrence of the ulcer, although the patient's metabolic profile remained unstable. Multimodal therapy combining UVC and laser may constitute a useful and side-effect-free alternative treatment modality for the induction of wound healing post metatarsal amputation in patients with unhealed diabetic ulcers.
