Actinic keratoses (AK) are precancerous lesions that develop on chronically sun-exposed skin. They frequently require prophylactic field treatment due to the risk of progression to squamous cell carcinoma. Topical treatment with 5-fluorouracil (5-FU) yields near complete AK resolution, yet leaves a patient with an exuberant erythematous treatment site, which may be embarrassing and/or uncomfortable. We report a case of a patient with diffuse facial AK who was treated with 5-FU twice daily for 2 weeks, resulting in fiery-red erythema and disrupted barrier indices. Application of pure ultra white petroleum jelly, an emollient preferred by dermatologists for post-operative wound healing, resulted in drastic decreased erythema and recovery time of post-treatment transepidermal water loss and hydration, compared to the contralateral, non-petrolatum-treated side. Additionally, petrolatum use did not disrupt the AK resolution endpoint. We suggest that petroleum jelly be used for the repair of 5-FU-induced barrier disruption and erythema to promote greater patient adherence.

The authors present the case of a 59-year-old male patient, whose first kidney transplantation was in 1983 and the second in 2000. The first squamous cell carcinoma appeared on the skin 2 years after the first transplantation. Since 2003, at least two precancerous lesions or non-melanoma skin tumors have been removed surgically yearly. These cancers appeared predominantly on the sun-exposed skin, and were multiple. As these tumors could behave aggressively and prone to recurrence, complex treatment was applied, which included a switch in immunosuppressive drugs and the application of field therapies. The authors give an overview of these treatment options in relation to the case presentation, emphasizing that not only early detection and active treatment of the precancerous lesions and skin cancers are essential, but education of proper sun-protection methods and dermatology care are also important in order to avoid the development of these tumors.

A competent epidermal barrier is crucial for terrestrial mammals. This barrier must keep in water and prevent entry of noxious stimuli. Most importantly, the epidermis must also be a barrier to ultraviolet radiation (UVR) from the sunlight. Currently, the effects of ultraviolet radiation on epidermal barrier function are poorly understood. However, studies in mice and more limited work in humans suggest that the epidermal barrier becomes more permeable, as measured by increased transepidermal water loss, in response UVR, at doses sufficiently high to induce erythema. The mechanisms may include disturbance in the organisation of lipids in the stratum corneum (the outermost layer of the epidermis) and reduction in tight junction function in the granular layer (the first living layer of the skin). By contrast, suberythemal doses of UVR appear to have positive effects on epidermal barrier function. Topical sunscreens have direct and indirect protective effects on the barrier through their ability to block UV and also due to their moisturising or occlusive effects, which trap water in the skin, respectively. Some topical agents such as specific botanical extracts have been shown to prevent the loss of water associated with high doses of UVR. In this review, we discuss the current literature and suggest that the biology of UVR-induced barrier dysfunction, and the use of topical products to protect the barrier, are areas worthy of further investigation.

AbstractEarly detection of cervical lesions, accurate diagnosis of cervical lesions, and timely and effective therapy can effectively avoid the occurrence of cervical cancer or improve the survival rate of patients. In this paper, the spectra of tissue sections of cervical inflammation (n = 60), CIN (cervical intraepithelial neoplasia) I (n = 30), CIN II (n = 30), CIN III (n = 30), cervical squamous cell carcinoma (n = 30), and cervical adenocarcinoma (n = 30) were collected by a confocal Raman micro-spectrometer (LabRAM HR Evolution, Horiba France SAS, Villeneuve d’Ascq, France). The Raman spectra of six kinds of cervical tissues were analyzed, the dominant Raman peaks of different kinds of tissues were summarized, and the differences in chemical composition between the six tissue samples were compared. An independent sample t test (p ≤ 0.05) was used to analyze the difference of average relative intensity of Raman spectra of six types of cervical tissues. The difference of relative intensity of Raman spectra of six kinds of tissues can reflect the difference of biochemical components in six kinds of tissues and the characteristic of biochemical components in different kinds of tissues. The classification models of cervical inflammation, CIN I, CIN II, CIN III, cervical squamous cell carcinoma, and cervical adenocarcinoma were established by using a support vector machine (SVM) algorithm. Six types of cervical tissues were classified and identified with an overall diagnostic accuracy of 85.7%. This study laid a foundation for the application of Raman spectroscopy in the clinical diagnosis of cervical precancerous lesions and cervical cancer.

Összefoglaló. Bevezetés és célkitűzés: A szerzők a posztoperatív fájdalom és a sebgyógyulás tekintetében prospektív vizsgálattal hasonlították össze gyermekeken (67 fő, 1–12 év) a hagyományos hidegeszközzel történő extracapsularis tonsillectomiát (23 fő) a microdebriderrel (23 fő) és a coblatorral (21 fő) végzett intracapsularis tonsillotomiával. Módszer: A vizsgálatok a betegek által kitöltött kérdőívek, valamint prospektív klinikai adatgyűjtés alapján történtek. Eredmények: Az intracapsularis tonsillotomia gyógyulási idejét 50%-kal rövidebbnek találtuk, és az első 13 napban szignifikánsan kevesebb fájdalommal és fájdalomcsillapító igénnyel járt, mint az extracapsularis tonsillectomia eseteiben. A tonsillotomiás csoporton belül egyedül a posztoperatív első napi fájdalom tekintetében észleltünk szignifikáns különbséget a két különböző módszer között a coblator javára (p<0,05). A vizsgálatokat retrospektív áttekintéssel is kiegészítettük, 4 évi gyermek- (1–15 éves) tonsillaműtéten átesett beteganyagunk (1487 fő) eredményeinek feldolgozásával. Tonsillectomia (1253 fő) után 7,7%-os utóvérzési arányt észleltünk, műtéti vérzéscsillapításra 1,3%-ban volt szükség. Tonsillotomia esetén (234 fő) 0,43%-os utóvérzési arányt regisztráltunk. Ebben a csoportban vérzés miatt nem, de 2 esetben ismételt obstrukciót okozó hypertrophia, 1 esetben góctünetek miatt reoperációt végeztünk (1,28%). Következtetés: Eredményeiket a szerzők a nemzetközi ajánlások tükrében elemezték. Az intracapsularis tonsillotomia kisebb fájdalommal, kisebb vérzéssel és kisebb megterheléssel jár. A közösségbe való aktív visszatérés akár egy hét után lehetséges a tonsillectomiára jellemző 3 héttel szemben, mindez jelentős szocioökonómiai előnyökkel járhat. Orv Hetil. 2020; 161(45): 1920–1926. Summary. Introduction and objective: Examining operated children in this prostective study inditerscompared (67 pts, 1–12 yrs) the extracapsular tonsillectomy with conventional cold-knife (23 pts) to extracapsular tonsillotomy with microdebrider (23 pts) and coblator (21 pts) for postoperative pain and wound-healing disorders. Method: The study was based on patient-completed questionnaires as well as prospective clinical data collection. Results: The recovery time of intracapsular tonsillotomy was found less than 50%, with less pain than in the cases of extracapsular tonsillectomy. Postoperative pain was significantly less in the tonsillototomy group than the tonsillectomy group. Within the tonsillotomy group, a significant difference was observed between the two different methods in favor of the coblator for only the postoperative first-day pain. The studies were supplemented with a retrospective review by processing the 4 yrs results of their pediatric (1–15-yrs) patients who underwent tonsillectomy (1487 pts). After tonsillectomy (1253 pts), a postoperative bleeding rate of 7.7% was observed, and surgical hemostasis was required in 1.3%. In the case of tonsillotomy (234 pts), a postoperative bleeding rate of 0.43% was recorded. In this group, reoperation was not performed due to bleeding, whereas it was neccesary in 2 cases due to hypertrophy causing repeated obstruction, in 1 case due by virtue of focal symptomes (1.28%). Conclusion: Our results were analyzed on the basis of international recommendations. Intracapsular tonsillotomy is associated with less pain, less bleeding, and less strain. Active return to the community is possible after up to a week compared to the 3 weeks typical of tonsillectomy, all of which can have significant socioeconomic benefits.

Adenoid squamous cell carcinoma (ASCC) is an uncommon but well recognized variant of squamous cell carcinoma. It has been reported to originate in the sun exposed skin of the head and neck region. Although rare, there are cases in records which have reported within the oral cavity and nasopharynx. Histologically the lesion shows areas of conventional squamous cell carcinoma along with atypical epithelial cells forming an adenoid pattern. There are insufficient reported cases to establish likely behaviour. Here we report two additional cases of adenoid squamous cell carcinoma, one developing in the floor of mouth and another in the maxillary sinus both were reported in March 2010 in Mangalore, India.
