Airway management of a patient with linear immunoglobulin A bullous dermatosis:A case report

BACKGROUND There is limited literature on managing the airway of patients with linear immunoglobulin A(IgA)bullous dermatosis,a rare mucocutaneous disorder that leads to the development of friable bullae.Careful clinical decision making is necessary when there is a risk of bleeding into the airway,and a multidisciplinary team approach may lead to decreased patient morbidity during these high-risk scenarios,especially when confronted with an unusual cause for bleeding.CASE SUMMARY A 45-year-old African American female presented to our ambulatory surgical center for right corneal transplantation due to corneal perforation after blunt trauma in the setting of cicatricial conjunctivitis and diffuse corneal neovascularization from linear IgA bullous dermatosis.The diagnosis of IgA dermatosis was recent,and the patient had been lost to follow-up.The severity of the disease and extent of airway involvement was unknown at the time of the surgery.Significant airway bleeding was noticed upon intubation and the otorhinolaryngology team had to be called to the operating room.The patient required transfer to the intensive care unit where a multidisciplinary team was involved in her case.The patient was extubated on postoperative day 4.CONCLUSION A multidisciplinary approach to treating this disease is the best course of action before a surgical procedure.In our case,key communication between the surgery,anesthesia,and dermatology teams led to the quick and safe treatment of our patient’s disease.Ambulatory surgery should not be considered for these cases unless they are in full remission and there is no mucous membrane involvement.

Transient Acantholytic Dermatosis: A Case Report and Literature Review

Transient acantholytic dermatosis (TAD, Grover disease) is a benign skin disease with a nonspecific rash that may present as a reddish-brown, dermatomal edematous papule or herpetiform rash with a partially central horny plug. This disease is usually self-limiting and can subside within weeks or months, but it may also have a chronic progression with a trend towards long-term recurrence. The patient is an 80-year-old male who visited the clinic due to recurring erythema and blisters all over his body that had been present for over 2 years. Based on the patient’s course, laboratory tests and histopathological findings were consistent with the diagnosis. The final diagnosis was transient acantholytic dermatosis. The patient has a long course of the disease, a wide range of skin lesions and he has the different subtypes of pathological manifestations. This case and corresponding literature review help us have a clear understanding of Grover’s disease, which has received reference value for the diagnosis and treatment of this disease in clinical work.

Is it relevant a correct intimate cleansing in the treatment of vulvar dermatosis?

Background: Vulvar dermatoses are inflammatory disorders of genital skin causing itch, pain, dysuria and dyspareunia. Objective: To compare the efficacy of two intimate cleansers as adjuvants in the treatment of the two common vulvar dermatoses: Lichen sclerosus (LS) and lichen simplex chronicus (LSC). Method: 32 patients with the diagnosis of LS or LSC initially treated with Mometasone furoate 0.1% cream were then randomly assigned to receive either cleanser A (cleaner based on amigdalus dulcis, malva, jojoba oil, PCL solid, Hyaluronic acid) or cleanser B (cleaner based on Cocoyl Wtheat Amino Acids, Maltodextrins, Aveena sativa, Caprylic Glycol) twice a day in association with lanolin cream one application daily for 30 days, following which the lanolin cream was applied only when needed as a rescue treatment. The amount of the rescue cream used, rubbing, applicability and pleasantness of the product were classified before and after 60 days of treatment. Results: The differences between the two treatments for rubbing, applicability and pleasantness of the product were statistically non-significant, while “as needed” use of the emollient lanolin cream was significantly superior in a total number of doses in the B group versus the A group (8.25 vs 5.28 (P < 0.001). Conclusion: The parameters showed a high score for both the cleansers, demonstrating the acceptability of these products by the women. The best results of the cleaner A can be attributed to not only to the pool of moisturizing and emollient active ingredients but that of the soothing effects as well. This shows that the role of intimate cleanser is not only for vulval cleansing, but can also play a therapeutic role of moisturization and emollience.

Epidemiological Profile of Dermatosis among Automobile Repair and Maintenance Garages in the City of Parakou in 2020

Background: Occupational dermatoses, also called occupational dermatitis or occupational dermatitis, are very common in the workplace and are still a topical subject. All over the world, especially in developed countries. They handicap the professional activities of the workers. Purpose: To determine the epidemiological profile of dermatosis among automobile repair and maintenance garages in Parakou. Methods: It was a cross-sectional and descriptive study carried out from 20 April to 17 May 2020. The sampling method was non-probabilistic. Data collected from a questionnaire, clinical examination and worksite observation were analyzed with Epi Info 7.2.2.1 software. Results: The participation rate was 98.08%. The sex ratio (male/female) was 178. The mean age of the respondents was 25.80 ± 10.22 years. Respondents with less than 5 years of experience in the field were 61.22%. Mechanics were the most numerous. In the sample, 95.81% had frequent skin contact with fuels, 84.08% had contact with motor oils and 15.92% had contact with dilute battery electrolyte solutions. The frequency of dermatosis was 73.46%. Hands and wrists were the most affected seats (47.35%). Some (33.84%) wore them before the start of the activity in the garage but in 66.22% of them, the dermatosis had occurred because of their arrival in the garage. Among these skin diseases, keratoderma predominated at 80.01%. Conclusion: Dermatosis is very common among garage owners in Parakou.

Diagnostic Sign of Terra Firma-Forme Dermatosis

Background: Terra Firma-Forme Dermatosis (TFFD), a benign skin condition which presents with asymptomatic brown to black plaques which resemble dirty skin. Aim: To document a new case presentation with TFFD in the Arab region which is considered as one of the differential diagnoses of dirty neck. Case presentation: A 15-year-old girl presented with a history of asymptomatic brownish dirt-like lesion on the nape and sides of the neck for 4-years duration, not resolved by wash with water and soap and confused with other dermatoses like acanthosis nigricans or atopic dermatitis. The diagnosis of TFFD was confirmed when the lesions were completely resolved after gentle swabbing with 70% isopropyl alcohol. Conclusion: TFFD is rarely reported in Arab region and should be considered when evaluating cases of dirty neck-like presentation of atopic dermatitis or acanthosis nigricans.

Regulation Mechanism of TFP on TGF-β1/STAT3 Signaling Pathway in Immune-mediated Liver Injury in Mice

[Objectives]To study the effect of total flavonoids extracted from Polygonum perfoliatum L.(TFP)on immune-mediated liver injury induced by bacillus Calmette-Guerin plus lipopolysaccharide(BCG+LPS)in mice,and to explore its action mechanism.[Methods]60 Kunming mice were divided into normal group,model group,control group(bifendate)and TFP low,medium and high dose groups according to random number table method,with 10 mice in each group.On the first day of modeling,mice were injected with 0.2 mL of BCG solution(12.5 mg/mL)through the tail vein,and on the eleventh day,0.2 mL of LPS(37.5μg/mL)were injected into the tail vein to prepare a mouse model of immune-mediated liver injury;from the first day of modeling,the normal group and the model group were administered intragastrically with the corresponding volume of distilled water,and the bifendate group and the TFP high,medium,and low dose groups were administered intragastrically with the corresponding doses once a day for 11 d.After the last time administration,fasting but giving water for 16 h,took blood from eyes,then collected the liver tissue.The levels of alanine transaminase(ALT)and aspartate transaminase(AST)in serum were detected by biochemical method;transforming growth factor-β1(TGF-β1),intercellular adhesion molecule-1(ICAM-1),interleukin-6(IL-6)and interleukin-1β(IL-1β)expression levels in liver tissue were detected by enzyme-linked immunosorbent assay(ELISA);phosphorylated protein tyrosine kinase JAK-2(p-JAK2),phosphorylated signal transducer and activator of transcription 3(p-STAT3)protein expression levels were detected by Western Blot method;the degree of liver tissue lesions was detected by HE staining.[Results]Compared with the model group,the levels of ALT and AST in the serum of mice in each dose group of TFP(high dose 600 mg/kg,medium dose 400 mg/kg,and low dose 200 mg/kg)were reduced,and the activities of T-SOD and GSH-Px were increased;the content or expression ofβ1,ICAM-1,IL-6,IL-1βdecreased,and the expression of p-JAK2 and p-STAT3 protein decreased;pathological sections showed that the degree of inflammatory necrosis and the degree of lesions in the liver tissues of each dose group of TFP were reduced by varying degrees.[Conclusions]TFP has a protective effect on BCG+LPS-induced immune-mediated liver injury in mice.The mechanism may be related to regulating the phosphorylation level of JAK2 and inhibiting the inflammatory reaction,thereby regulating the TGF-β1/STAT3 signaling pathway and improving the immune-mediated liver injury.

Combination treatment of inflammatory bowel disease:Present status and future perspectives

The treatment of patients with inflammatory bowel disease(IBD),especially those with severe or refractory disease,represents an important challenge for the clinical gastroenterologist.It seems to be no exaggeration to say that in these patients,not only the scientific background of the gastroenterologist is tested,but also the abundance of“gifts”that he should possess(insight,intuition,determ-ination,ability to take initiative,etc.)for the successful outcome of the treatment.In daily clinical practice,depending on the severity of the attack,IBD is treated with one or a combination of two or more pharmaceutical agents.These combin-ations include not only the first-line drugs(e.g.,mesalazine,corticosteroids,antibiotics,etc)but also second-and third-line drugs(immunosuppressants and biologic agents).It is a fact that despite the significant therapeutic advances there is still a significant percentage of patients who do not satisfactorily respond to the treatment applied.Therefore,a part of these patients are going to surgery.In recent years,several small-size clinical studies,reviews,and case reports have been published combining not only biological agents with other drugs(e.g.,immunosuppressants or corticosteroids)but also the combination of two biologi-cal agents simultaneously,especially in severe cases.In our opinion,it is at least a strange(and largely unexplained)fact that we often use combinations of drugs in a given patient although studies comparing the simultaneous administration of two or more drugs with monotherapy are very few.As mentioned above,there is a timid tendency in the literature to combine two biological agents in severe cases unresponsive to the applied treatment or patients with severe extraintestinal manifestations.The appropriate dosage,the duration of the administration,the suitable timing for checking the clinical and laboratory outcome,as well as the treatment side-effects,should be the subject of intense clinical research shortly.In this editorial,we attempt to summarize the existing data regarding the already applied combination therapies and to humbly formulate thoughts and suggestions for the future application of the combination treatment of biological agents in a well-defined category of patients.We suggest that the application of biomarkers and artificial intelligence could help in establishing new forms of treatment using the available modern drugs in patients with IBD resistant to treatment.
