Recurrent Talaromyces marneffei Infection Presenting with Intestinal Obstruction in a Patient with Systemic Lupus Erythematosus.

Talaromyces marneffei is an important opportunistic pathogen mainly afflicting the HIV-infected patients, in rare instance, it could cause infection in non-HIV-infected individuals. We report a 51-year-old Chinese woman who, with histories of SLE for 14 years and disseminated talaromycosis for 4 years, occurred partial intestinal obstruction that was demonstrated to be caused by Talaromyces marneffei infection. The randomly amplified polymorphic DNA results of paraffin-embedded tissues from both the present episode and the previous infection suggested that the present infection was a recurrent. The patient was performed excision of involved intestine and treated with oral itraconazole at a daily dose of 400 mg for 3 months, leading to an excellent response. However, she died with unknown reason more than a year later. We also reviewed the literature on Talaromyces marneffei infection associated with SLE as well as intestinal talaromycosis alone.

Aquagenic cutaneous disorders.

Aquagenic cutaneous disorders, which include aquagenic urticaria, aquagenic pruritus, and aquagenic acrokeratoderma, are a group of rare diseases characterized by skin lesions or discomfort induced by brief contact with water. Aquagenic urticaria is characterized by pruritic wheals that occur at the sites of water contact, either immediately or within minutes, and disappear within 30-60 min after water removal. Aquagenic pruritus presents with severe pruritus or a stinging, tingling, or burning sensation without any visible skin changes. These symptoms occur immediately or within minutes after the skin is exposed to water, lasting for one hour or longer. Aquagenic acrokeratoderma usually presents with whitish papules and plaques, edema, and hyperwrinkling within 2-20 min after brief exposure to water; symptoms disappear within minutes to one hour after drying. The pathomechanisms of these diseases are not yet fully understood, and their diagnosis is primarily based on clinical features. Treatment remains a challenge. Herein, we review the literature regarding these unusual disorders.

Hybrid eccrine gland and hair follicle hamartoma: a new entity of adnexal nevus.

Eccrine nevus shows increase in number or size of eccrine glands, whereas hair follicle nevus is composed of densely packed normal vellus hairs, and eccrine-pilar angiomatous nevus reveals increase of eccrine, pilar, and angiomatous structures. No case with increased number of both eccrine glands and hair follicles only in the dermis has been previously reported. A 10-month-old girl presented with cutaneous hamartoma with overlying skin hyperpigmentation on her left hypochondrium since 3 months of age, in whom the lesion was completely excised. Histopathology demonstrated evidently increased number of both eccrine glands and hair follicles in the dermis with reactive hyperplasia of collagen fibers. No recurrence occurred after the tumor was completely excised. A term "hybrid eccrine gland and hair follicle hamartoma" is proposed for this unique lesion.

Recurrent facial erythema with burning sensation and increased temperature: a variant of erythromelalgia or a new entity?

OBJECTIVE: Erythromelalgia is a rare clinical syndrome characterized by episodic attacks of burning pain, erythema, and increased temperature, primarily affecting the extremities, and in rare instances, involving the ear, face, neck, and the scrotum. The dermatoscopic features of erythromelalgia in a case with solely facial involvement have never been described previously. OBSERVATIONS: We describe a 14-year-old female who presented with erythema, burning sensation, and warmth on her face only, which mimic the features of erythromelalgia. Physical examination showed higher temperature on the involved cheeks than on axillas during the episode, while the temperature on both areas was the same between episodes. Dermatoscope showed more dilated vessels inside the erythema during the episodes than between the episodes. The symptoms had excellent response to the combination treatment of gabapentin, indomethacin, and topical lidocaine compounds. CONCLUSIONS: The present case is considered to be a variant of erythromelalgia. Its erythema may be resulted from the dilated vessels. Combination of modalities may provide effective management for erythromelalgia. "Erythermalgia" may be better than "erythromelalgia" to describe such conditions.

Mandibuloacral dysplasia type A-associated progeria caused by homozygous LMNA mutation in a family from Southern China.

BACKGROUND: Mandibuloacral dysplasia type A (MADA) is a rare autosomal recessive disorder, characterized by growth retardation, skeletal abnormality with progressive osteolysis of the distal phalanges and clavicles, craniofacial anomalies with mandibular hypoplasia, lipodystrophy and mottled cutaneous pigmentation. Some patients may show progeroid features. MADA with partial lipodystrophy, more marked acral, can be caused by homozygous or compound heterozygous mutation in the gene encoding lamin A and lamin C (LMNA). MADA and Hutchinson-Gilford progeria syndrome are caused by the same gene and may represent a single disorder with varying degrees of severity. MAD patients characterized by generalized lipodystrophy (type B) affecting the face as well as extremities and severe progressive glomerulopathy present heterozygous compound mutations in the ZMPSTE24 gene. CASES PRESENTATIONS: We described a rare pedigree from Southern China, among them all three children presented with phenotypes of MADA associated progeria. The two elder sisters had developed severe mandibular hypoplasia associated progeria since the age of 1 year. The eldest sister showed a progressive osteolysis. The youngest son of 10 months showed severer lesions than those of his sisters at the same age, and presented possible muscle damage, and his symptoms progressed gradually. Three genes mutations including LMNA, ZMPSTE24 and BANF1 were tested in the family. LMNA gene sequencing revealed a homozygous missense mutation, c.1579C > T, p.R527C for all three siblings, and heterozygous mutations for their parents, whereas no mutations of ZMPSTE24 and BANF1 genes was detected among them. CONCLUSIONS: The same homozygous mutation of c.1579C > T of LMNA gene led to MADA associated progeria for the present family. The course of osteolysis for MADA is progressive.

Erythema associated with pain and warmth on face and ears: a variant of erythermalgia or red ear syndrome?

Erythermalgia is a rare cutaneous disorder characterized by attacking of erythema, pain and increased temperature, which primarily involves the extremities and may infrequently extend to the neck, face, ears and even the scrotum. We reported an 18-year-old woman who presented with 3 years history of sole involvement of attacking erythema, pain and warmth over her face and ears without any other associations. The frequency and severity of the flares progressed gradually during the course. Cutaneous examination revealed erythema, increased temperature and tenderness on the face and ears during the flare. The symptoms could be relieved rapidly by cooling. Dermatoscope showed that vessels inside the erythema were more dilated during the episode than after application of ice. The lesion is considered a rare variant of erythermalgia with sole involvement of face and ears. The symptoms had mild response to oral antihistamines, topical steroids and tacrolimus, but had excellent response to the combinative therapy of aspirin and paroxetins.

Combination of fractional carbon dioxide laser with recombinant human collagen in periocular skin rejuvenation.

BACKGROUND: The most visible sign of facial aging is often seen in the periocular area. However, periocular rejuvenation remains challenging due to the particularity of periocular anatomic locations. AIMS: We aimed to evaluate the efficacy and safety of the fractional-ablative CO2 laser-facilitated recombinant human collagen permeation in periocular rejuvenation. PATIENTS/METHODS: This 3-month prospective single-blinded and self-controlled trial enrolled 26 patients with periocular aging who underwent the treatments of fractional-ablative CO2 laser along with laser-facilitated recombinant human collagen permeation. Following the treatments, the patients were quantitatively assessed by various periocular skin aging indices before and after the treatment and monitored for any related adverse events. RESULTS: The patients showed significant improvements with the periocular skin aging indices 3 months after the treatments, which were detailed with a 47.3% decrease in lower eyelid skin rhytids, a 41.4% decrease in the lower eyelid skin texture, a 35.0% decrease in the static crow's feet, a 29.3% decrease in the amount of upper eyelid laxity, and a 20.2% increase in the MRD1 as compared with baseline (p < 0.05). Moreover, total skin thickness under ultrasound was increased in both upper and lower eyelids (5.6% and 3.3%, p < 0.05, respectively). Moreover, six patients (23.1%, 6/26) had erythema for 2 weeks, and two (2/26, 7.7%) had mild hyperpigmentation for 3 months. CONCLUSIONS: Fractional-ablative CO2 laser combined with laser-facilitated recombinant human collagen permeation can be a safe and effective treatment for periocular rejuvenation.

Localized secondary erythromelalgia in an 11-year-old boy.

We report an 11-year-old boy with localized secondary erythromelalgia on his left medial thigh. The episodes responded well to indomethacin and prednisone but recurred after the medications were stopped. The disease was stable after being treated for 5 months.

Recalcitrant nodular scabies showing excellent response to tofacitinib: five case reports.

Scabies is a contagious skin condition caused by Sarcoptes scabiei, and it is always associated with an intense, unbearable, nocturnal deteriorating itch. Its presentations include classic burrows, erythema, pruritic papules, pustules, vesicles, and inflammatory nodules, with diffuse or localized distribution on the finger webs, wrist flexors, elbows, axillae, buttocks, genitalia, and breasts. Nodular scabies is an uncommon clinical variant of scabies. Its management is still challenging for some patients up to date, although topical, intralesional or systemic corticosteroids, topical calcineurin inhibitors, and crotamiton as well as cryotherapy alone or in different combinations are used. We here report five male patients of nodular scabies, aged between 14 and 25 years, who had classical scabies that had been cured by sulfur ointment for at least 4 weeks except for their itching nodules, and their residual pruritic nodules also failed in previous treatments including antihistamines, topical applying and intralesional injection of steroids as well as topical tacrolimus in different combinations before being recruited to this study. The patients were administered tofacitinib 5 mg, twice a day, which led to excellent and rapid improvement for both lesions and symptoms after 1-4 weeks of treatment, respectively, without any associations. During 6 months of follow-up, only one had re-infection of scabies associated with nodules that were cured by sulfur ointment and tofacitinib again. No adverse reaction was observed. The present results suggested that tofacitinib might be a potential agent for nodular scabies with excellent response.

Auricular erythermalgia showing excellent response to itraconazole: a case report.

Erythermalgia, a rare painful disorder, is characterized by recurrent pain attacking, warmth, and erythema that mainly involves the distal extremities. Red ear syndrome shares similar clinical features of erythermalgia afflicting the external ear with unilateral/bilateral distribution. The treatments of both diseases are still difficult without controlled therapeutics available up to date. A 12-year-old boy was referred because of 3 years of recurrent attacking of painful erythema and warmth that involved the ears alone, the episodes occurred several times daily with duration of dozens of minutes to hours for each flare. The symptoms could be relieved by cold water and triggered by heat stimuli as well as exciting and movement, and showed mild response to gabapentin, celecoxib, and topical lidocaine compounds in combination, but moderate to blocking injection of botulinum toxin to nervus auricularis magnus. However, systemic itraconazole 200 mg daily resulted in an excellent response after 5-week treatment, leading to milder erythema, warmth and burning sensation, shorter duration, and fewer relapses. The treatment continued for 6 months and then itraconazole was decreased to 100 mg daily for another 6 months until it was stopped, with maintenance of good conditions. In 3 months of follow-up after the treatment ceased, the patient had only 7 to 8 attacks over 10 days presenting as tolerable erythema that lasted for less than 10 min and relieved spontaneously, with absence of warmth and no need of treatment. We considered the patient to be a variant of erythermalgia rather than a red ear syndrome. The results showed that erythermalgia might involve the ears alone and itraconazole might be a potential agent for its treatment.

In vitro activities of erythromycin, tetracycline and levofloxacin alone and in dual combinations against ureaplasma spp.

PURPOSE: It was the aim of our study to evaluate the in vitro activities of tetracycline (TET), erythromycin (ERY) and levofloxacin (LVX) alone and in dual combinations against ureaplasmas. METHODS: The minimum inhibitory concentrations (MICs) of 51 ureaplasmal strains were determined by microdilution assay. RESULTS: TET was the most active when the antibiotics were used alone. The combinations resulted in significantly decreased MICs for every agent compared with the use of single antibiotics (p < 0.05, respectively), except for ERY in the ERY-LVX pair (p > 0.05), and decreased the MICs more significantly in the strains with an MIC ≥4 mg/l compared with MIC <4 mg/l, except for the TET-ERY pair. The ERY-LVX pair increased ERY MICs significantly in the MIC <4 mg/l group (p < 0.05). The combinations resulted in more beneficial MICs in strains where both agents had an MIC ≥4 mg/l compared with those where either had an MIC ≥4 mg/l, as well as in strains where either agent had an MIC <4 mg/l compared with those where both had an MIC <4 mg/l. CONCLUSIONS: Drugs in dual combinations always give more beneficial MICs against ureaplasmas than one agent alone. Combinational benefits prefer strains with a higher initial MIC.

Interdigital ulcer: an unusual presentation of Candida infection.

Interdigital ulcer is an exceptionally rare condition while erosio interdigitalis blastomycetica is common for candidiasis. Four Chinese patients with Candida interdigital ulcers were reported. The exudates were examined directly and cultured for fungi. Skin biopsies were stained with haematoxylin-eosin and periodic acid Schiff. There were a man and three women (age range: 34-56 years) who presented with 1- to 3-month history of chronic cutaneous ulcer on the interdigital web of hand or foot. The lesions were located on hand for one woman, and on the left foot for the rest. The patients had poor response to the previous treatment of topical steroids and oral antimicrobials. Candida albicans was isolated from a man and two women, Candida tropicalis from another woman. Biopsy specimens revealed yeast and mycelium as well as inflammatory infiltrate in necrotic tissue in two patients; only inflammatory cells in the other two. The patients had complete remission with oral itraconazole and topical bifonazole cream therapy for 3- to 5-week. Candida species may cause interdigital ulcer on hand or foot. Oral itraconazole and topical bifonazole may be an optional therapy for such an ulcer.

Disseminated Penicillium marneffei infection in an SLE patient: a case report and literature review.

Penicillium marneffei is an important opportunistic pathogen in Southeast Asia in HIV-positive individuals, but it rarely infects non-HIV ones. Four SLE patients with disseminated penicilliosis had been previously reported out of which 3 died. We describe a 46-year-old Chinese woman who had a 10 years history of SLE, associated with disseminated Penicillium marneffei infection, which presented as fever, subcutaneous masses, and fine nodular shadows disseminated over lung fields. She was initially misdiagnosed as miliary tuberculosis and panniculitis that did not respond to anti-tubercular drugs and prednisone. The correct diagnosis was finally made by histopathology and tissue culture and also culture from exudate. She responded well to antifungal therapy in the form of intravenous amphotericin B for 2 weeks followed by itraconazole plus fluconazole. The cutaneous lesions were cured leaving behind scars by secondary suture after times of epluchage, and the fine nodular shadows over lungs disappeared finally. She had no recurrence on 8 months of follow-up. We also review the literature on this topic.
