Arterial tortuosity syndrome is a rare hereditary autosomal recessive connective tissue disorder characterized by elongation and tortuosity of the large- and medium-sized arteries. We present the case of a 13-year old child with arterial tortuosity syndrome who underwent occipital encephaloduroarteriomyosynangiosis for posterior circulation insufficiency. The constellation of clinical features in our patient portended significant anesthetic concerns, including difficult airway due to craniofacial abnormalities, risk of stroke, and myocardial infarction due to intracerebral and coronary arterial tortuosity and stenosis. The pertinent anesthetic implications are summarized, and we describe the anesthetic technique and use of multimodal neuromonitoring relevant for the case.

BACKGROUND: Although various treatments are currently available for primary cutaneous amyloidosis (PCA), there is no entirely satisfactory treatment. Recently, fractional ablative lasers are claimed to have therapeutic effects for PCA. OBJECTIVE: To evaluate the efficacy and safety of fractional Er:YAG laser for the treatment of PCA. METHODS AND MATERIALS: Ten patients with macular and lichen amyloidosis received 4 treatment sessions with 4-week intervals. The outcome was assessed clinically (degree of pigmentation, rippling, lichenification, and itching) through photographs and histologically (amount of amyloid, melanin, epidermal thickness, and depth of rete ridges) through biopsy specimens stained with hematoxylin-eosin, Congo red, and Fontana-Masson stain. Patients were followed up for 3 months after the final treatment. RESULTS: At 3-month follow-up, fractional Er:YAG laser exhibited a significant clinical and histological improvement. Patient satisfaction concurred with physicians' evaluations. Recurrence was detected in 1 patient. CONCLUSION: In light of the authors' findings, fractional Er:YAG laser offered a great clinical and histological efficacy with excellent safety profile. Careful laser selection based on making a compromise between efficacies and safeties may improve outcome.

BACKGROUND: Dissecting cellulitis is a chronic inflammatory dermatosis that results in disfiguring and painful, purulent lesions. Treatment of patients with disease resistant to standard therapies, including intralesional or topical steroids or antibiotics, can be a dilemma for clinicians. METHODS: We performed a systematic review of the literature in November 2018 to find articles which presented treatment options and outcomes of patients who failed prior treatment with standard therapies. RESULTS: We identified 57 articles of interest, with 53 being case studies or series. Isotretinoin was the most often reported, but the response was limited. Biologics and laser therapy were used less often but demonstrated a better chance of remission. X-ray epilation and surgical excision demonstrated the best remission rates but can be complicated by serious morbidity. CONCLUSION: We propose a regimen for the treatment of recalcitrant cases of dissecting cellulitis. In the future, more robust studies including randomized control trials are needed to identify the preferred treatment options for refractory dissecting cellulitis.

OBJECTIVE: This aim of this study was to determine the effect of 1540-nm nonablative fractional erbium on macular amyloidosis. METHODS: This phase-II clinical trial study has been performed with parallel group with blinding of the evaluator. The skin lesions of the patients (15 patients and 30 lesions) with cutaneous macular amyloidosis were randomly assigned into laser and no-treatment groups. In the laser group, treatment was performed by 1540-nm nonablative fractional erbium laser. Thereafter, the patients' lesions were compared in terms of pigmentation, rippling, thickness, and subjective response. RESULTS: The lesions of the intervention group significantly improved in the three-month follow-up compared to the control group (in the control and intervention group, improved pigmentation was observed in 20 and 53.3% with p = .02, improved rippling in 6.7 and 60% with p = .007, diminished lichenification in 0 and 53.1% with p = .007, and overall lesion improvement in 20 and 60% with p = .03, respectively). In investigating the subjective response through patient global assessment, the patients in the intervention group had a greater satisfaction (p = .01). There was a considerable improvement of pruritus in the intervention group (p = .001). CONCLUSIONS: Use of 1540-nm nonablative fractional erbium laser offered a suitable efficacy to treat macular amyloidosis without significant complications.

Abstract Secondary osteoma cutis is a phenomenon that may occur in several conditions. When it occurs in a melanocytic nevus it is named osteonevus of Nanta, an event considered uncommon and characterized by the presence of bone formation adjacent or interposed with melanocytic cells. There are reports of its occurrence in various melanocytic lesions, being more frequently associated with intradermal nevus. We report a case of osteonevus of Nanta in combined nevus, possibly the first description of this association.

Perifolliculitis capitis abscedens et suffodiens (PCAS) is a rare, chronic, suppurative and inflammatory scalp disease with aetiology and pathogenesis not completely understood. The treatment of PCAS usually represents a challenging problem with frustrating outcome (1). Photodynamic therapy (PDT) is an approach considered to be useful to treat tumors, bacterial and fungal infections (2-4). We report 9 cases of patients who suffered from PCAS in varying degrees. Photodynamic therapy combined with surgery were used in these cases and the results were satisfactory. In conclusion, photodynamic therapy may provide a new way to treat PCAS.

Macular amyloidosis (MA) is a common form of primary localized cutaneous amyloidosis, characterized by the eruption of brown pigments of the skin with a rippled pattern. MA can be of cosmetic concern for patients, and its treatment is challenging. In this study, we aimed to find new effective approaches for MA treatment. A total of 39 patients with the clinical diagnosis of MA were treated with two types of laser therapy, and the effectiveness of each approach was examined. Fractional Q-switched 10.64 nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser therapy was compared with a combination of fractional Q-switched 10.64 nm Nd:YAG laser and long-pulsed fractional erbium:YAG laser therapy. Melanin biometric measurements were performed using a Mexameter, objective image-based evaluation was carried out, and the itching score and patient satisfaction were examined. Mexameter-based analysis showed that both types of laser therapy were effective in the treatment of MA, causing a significant decrease in the amount of melanin in the treated areas (P < 0.05). Also, combination of two types of laser therapy was significantly more effective than one type alone (P < 0.05). The itching score significantly decreased in patients undergoing a combination of laser therapies. Also, a positive correlation was observed between the amount of melanin and degree of itching in the treated areas. Moreover, analysis of patient satisfaction showed that more than 90% of patients had excellent satisfaction with combination laser therapy. The results confirmed the significant positive effects of both fractional Nd:YAG laser alone and in combination with fractional erbium:YAG laser therapy considering the reduction in melanin content; however, combination of two types of laser therapy was more effective than one type alone.

Basaloid follicular hamartoma is a rare, benign and superficial malformation of hair follicles, characterized histologically by epithelial proliferation of basaloid cells with radial disposition. It can be mistaken for basal cell carcinoma. Even though these hamartomas are considered benign lesions, malignant transformation has rarely been reported. We report the case of a 45-year-old healthy woman, with linear, unilateral basaloid follicular hamartoma which developed inflamed papules histologically suggestive of basal cell carcinoma. We believe that identification of local inflammation could be a clinical clue to guide us towards a malignant transformation of basaloid follicular hamartoma.

Dowling-Degos disease (DDD) is a rare autosomal-dominant genodermatosis with limited treatment possibilities. Although the efficacy of ablative laser therapy has been reported, we sought to examine the efficacy of fractional versus full ablative laser therapy in a female patient with DDD in a split-side report. We treated the lesions on the right side of the patient's upper abdomen with an ablative fractional CO2 laser and the lesions on the left side of the upper abdomen with a full ablative Er:YAG laser (erbium-doped yttrium aluminium garnet laser) three times at monthly intervals. After three laser sessions, the lesions treated with the Er:YAG laser showed a complete response, whereas the fractional CO2 laser treatment was less effective. After the three treatments were performed, the right side of the patient's upper abdomen and portions of her lower abdomen and chest were also treated with the Er:YAG laser in full ablation mode with the same settings. After 1 year of follow up, there was no recurrence observed. Lasers Surg. Med. © 2018 Wiley Periodicals, Inc.

BACKGROUND: Loeys-Dietz syndrome is associated with arterial tortuosity and aortic dissection. Pregnancy may be a period of increased risk for aortic dissection. CASE: A 16-year-old primigravid girl was referred to our center with a family history of aortic dissection. Loeys-Dietz syndrome was suspected, and genetic testing confirmed the TGFß2 (c.988C>T) mutation. A cesarean delivery was performed at 36 weeks of gestation, with no cardiovascular complications. In this case, the uterine vessels were significantly tortuous; this may be an additional finding in Loeys-Dietz syndrome. CONCLUSION: Women with Loeys-Dietz syndrome warrant special consideration in obstetric management secondary to the risk for aortic dissection. It is recommended that a multidisciplinary team with knowledge about connective tissue disorders and expertise in aortic surgery coordinate maternal obstetric and cardiovascular care.
