RESUMEN

In this study, we investigated the outcomes of laparoscopic approaches for adrenal tumor resection in 67 patients from a single center with a median age of 51 (range 40-79). Predominantly comprising women, the majority of patients were overweight or obese. Adrenal tumors larger than 6 cm were mostly treated using the laparoscopic transperitoneal method (p < 0.001). Our results revealed that patients subjected to the retroperitoneal approach exhibited quicker recovery, as evidenced by faster resumption of oral intake and ambulation, along with reduced intraoperative blood loss and shorter hospitalization (p-value < 0.05). In contrast, patients subjected to the transperitoneal approach experienced minimal complications, though not statistically significant, despite the technique's intricacy and slower recovery. These findings emphasize the significance of tailoring the surgical approach to individual patient characteristics, with particular emphasis on the tumor size. The choice between the retroperitoneal and transperitoneal methods should be informed by patient-specific attributes to optimize surgical outcomes. This study underscores the need for a comprehensive evaluation of factors such as tumor characteristics and postoperative recovery when determining the most suitable laparoscopic approach for adrenal tumor resection. Ultimately, the pursuit of individualized treatment strategies will contribute to improved patient outcomes in adrenal tumor surgery.

RESUMEN

Telogen effluvium post-COVID-19 is a condition characterized by the diffuse and reversible loss of scalp hair in the period following infection with SARS-CoV-2, and it is currently the second cause of alopecia in women. In the context of the COVID-19 infection, intense psychological stress contributes to alopecia appearance, along with systemic inflammation, autoimmune reactions, oxidative stress, and virally induced hypoxia. Cytokines with proinflammatory action and vasoactive substances negatively modulate the metabolism of some molecules, such as proteoglycans, involved in the hair follicle's growth cycle. Studies show that a large percentage of hairs will suddenly enter the catagen phase during a moderate to severe COVID-19 infection. In the present paper, we update the data from the literature with a clinical example. Our case highlighted that the telogen effluvium after infections with SARS-CoV-2 is reversible with appropriate dermatological treatment. For therapeutic success, informing the patient about this pathology's self-limited and reversible character is essential to reduce the emotional stress that may aggravate the disease.

RESUMEN

Dermoscopy is a non-invasive method of examination that aids the clinician in many ways, especially in early skin cancer detection. Melanoma is one of the most aggressive forms of skin cancer that can affect individuals of any age, having an increasing incidence worldwide. The gold standard for melanoma diagnosis is histopathological examination, but dermoscopy is also very important for its detection. To highlight the many roles of dermoscopy, we analyzed 200 melanocytic lesions. The main objective of this study was to detect through dermoscopy hints of melanomagenesis in the studied lot. The most suspicious were 10 lesions which proved to be melanomas confirmed through histopathology. The second objective of this study was to establish if dermoscopy can aid in estimating the Breslow index (tumoral thickness) of the melanomas and to compare the results to the histopathological examination. We found that the tumoral thickness may be estimated through dermoscopy, but the histopathological examination is superior. To conclude, the aim of this study was to showcase the versatility and many roles of dermoscopy, besides being one of the most important tools for early melanoma diagnosis.

RESUMEN

The increasing incidence for herpes zoster, including its ophthalmic form, is based on physiological (senescence) and acquired immunosuppression, particularly under oncologic treatment. The immunocompromised status of the patient favors the appearance of severe complications. The patient, aged 54, with chronic lymphocytic leukemia, presented 1 week from the onset with an erythematous, vesicular-bullous rash on the right trigeminal nerve's ophthalmic dermatome, marked edema, intense pain and large submandibular ganglion masses. There were cutaneous (necrotic ulcerations superinfected with methicillin-resistant Staphylococcus aureus), ocular (keratoconjunctivitis, total ophthalmoplegia, lagophthalmia, anterior hemorrhagic uveitis with hyphema and right eye blindness) and neurological (postherpetic neuralgia) complications. Systemic therapy was performed with acyclovir, antibiotics, supportive, rebalancing and symptomatics. With regards to treatment for skin ulcers, disinfection and necrectomy were performed, and epithelialization agents were subsequently administrated. At the ocular level, the ophthalmologist carefully monitored the patient and administered antivirals, antibiotics, epithelialization agents and autologous serum. The evolution of the case recorded severe, disabling complications, with extensive eyelid necrosis and definitive blindness. In this case, the severity of the ophthalmic herpes zoster (OHZ) was favored by the synergistic action of four factors: Acquired immunosuppression (chronic lymphocytic leukemia), delayed consultation, superinfectious lesions and patient non-compliance regarding the chronic lymphocytic leukemia treatment.

RESUMEN

Chronic wounds represent a major public health issue, with an extremely high cost worldwide. In healthy individuals, the wound healing process takes place in different stages: inflammation, cell proliferation (fibroblasts and keratinocytes of the dermis), and finally remodeling of the extracellular matrix (equilibrium between metalloproteinases and their inhibitors). In chronic wounds, the chronic inflammation favors exudate persistence and bacterial film has a special importance in the dynamics of chronic inflammation in wounds that do not heal. Recent advances in biopolymer-based materials for wound healing highlight the performance of specific alginate forms. An ideal wound dressing should be adherent to the wound surface and not to the wound bed, it should also be non-antigenic, biocompatible, semi-permeable, biodegradable, elastic but resistant, and cost-effective. It has to give protection against bacterial, infectious, mechanical, and thermal agents, to modulate the level of wound moisture, and to entrap and deliver drugs or other molecules This paper explores the roles of alginates in advanced wound-dressing forms with a particular emphasis on hydrogels, nanofibers networks, 3D-scaffolds or sponges entrapping fibroblasts, keratinocytes, or drugs to be released on the wound-bed. The latest research reports are presented and supported with in vitro and in vivo studies from the current literature.

RESUMEN

Syphilis is the most common sexually transmitted disease that mainly affects socially active people, with a fluctuating worldwide incidence over the years. A retrospective study was conducted over a period of 10 years (2009-2018) that included 396 patients with syphilis diagnosed and monitored by Sibiu County Emergency Clinical Hospital, Romania. During this period (2009-2018), we observed a decrease in the new cases of syphilis by 35.90%, and the average syphilis incidence was 9.90 new cases per 100,000 inhabitants. Syphilis was diagnosed more frequently in men with an average age of 35.39 years, from urban areas, with and educational level of grades 9-12, unmarried, workers, or without occupation. Out of the 396 patients with syphilis, about 6% were HIV coinfected. Over half of the HIV coinfected cases were declared MSM (men who have sex with men), and 40% of these cases were registered in 2018. The most common clinical stage of syphilis was the latent form (67.93%). Regarding the syphilis treatment regimen, we noted the transition from the classic regimen with benzathine-penicillin G (100% in 2009) to alternative therapies (mainly with cephalosporins) in 2018 (56.86%). Our findings showed that in the last 10 years in our county, the incidence of syphilis had a downward trend, but with an increase in syphilis-HIV co-infection and neurosyphilis cases.

RESUMEN

BACKGROUND: The cutaneous manifestations of coronavirus disease 2019 (COVID-19) have been covered insufficiently in the literature. METHODS: Thirty-nine patients admitted to the study hospital with confirmed COVID-19 who experienced various skin manifestations during hospitalization or in the convalescence period, were analysed retrospectively. RESULTS: Thirty-nine patients with COVID-19, admitted to the study hospital between 23 March and 12 September 2020, had intra-infectious rash or lesions of cutaneous vasculitis during convalescence. The most common cutaneous manifestations of COVID-19 were erythematous and erythematous papular rash. Twenty-seven of the 39 patients had anosmia (69.2%), 26 patients had ageusia (66.7%), 34 patients had pneumonia (87.2%) and 24 patients had intra-infectious enterocolitis (61.5%). Skin biopsies were rarely performed in these patients. This article reports the results of biopsies performed in two patients, showing histopathological and immunohistochemical changes in erythematous rash and erythema multiforme-like lesions. Both skin biopsies revealed early fibrous remodelling of the dermis, suggesting similarity with changes that occur in the lungs and other tissues in patients with COVID-19. CONCLUSIONS: Correlations between skin lesions and anosmia, ageusia and enteritis in patients with COVID-19 do not seem to be accidental, but are associated with a similar response to ACE2 receptor expression in these tissues.

RESUMEN

Autoimmune thyroiditis (AIT) is on the rise among the population, and is frequently associated with patients with acne vulgaris, especially females aged between 18-55 years old. The connection between the two is not fully elucidated. In this study, 236 patients diagnosed with acne in the dermatological office of the private Pelican Hospital and in few private dermatological offices from Oradea, Romania, during January 2018-December 2020, aged between 12 and 55 years old, were endocrinologically investigated to determine AIT and its influence on the severity of the acne. The values for the thyroid antibodies and thyroid-stimulating hormone (TSH) were determined for all of the subjects. The frequency of AIT in the study group was 72% and was associated with severe acne (p < 0.001). Patients with AIT with normal or hypofunction had more frequent severe acne than those with hyperfunction (p < 0.001, p = 0.002). The TSH and anti thyroidperoxidase (TPO) values did not influence the severity of the acne (p = 0.494; p = 0.111), while the anti-TG values were associated with severe acne (p = 0.007). The risk analysis indicated that raised values of anti-TPO (2.91 times greater) correlated with high anti-thyroglobulin (TG) values (4.36 times greater) doubled the risk of developing severe acne in patients. In acne evolution, the existence of AIT involves significant modifications.

RESUMEN

RATIONALE: Pityriasis rosea Gibert is an erythematous-papulosquamous dermatosis that frequently occurs in young adults. The etiopathogenesis of PR is still unknown, but is frequently associated with episodes of upper respiratory tract infections. It is likely that a new viral trigger of pityriasis rosea is the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). PATIENT CONCERNS: We present the case of a female patient in whom the diagnosis of pityriasis rosea led to the investigation and diagnosis of the SARS-CoV-2 infection. The patient presented to the Department of Dermatology for a 3 week duration of an extremely pruritic erythematous-squamous lesion, initially on the trunk and upper limbs, with extension to the lower limbs in the last week and the lesion respected the cephalic extremity, palms, and soles. One week before the rash, respiratory tract infection symptomatology was observed by the patient. At home, she underwent systemic treatment with antihistamines and topical medication with dermatocorticosteroids. The evolution was unfavorable, with the spread of the lesions and the accentuation of the pruritus. DIAGNOSES: Considering the actual epidemiological context, we performed a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) assay from nasal and pharyngeal swabs for coronavirus disease 2019 (COVID-19) to investigate the PR etiology. The patient had a positive RT-PCR result, and was confirmed with SARS-CoV-2 infection. INTERVENTIONS: Treatment was initiated with systemic corticosteroid therapy - hydrocortisone hemisuccinate 200 mg/day for 7 days, and loratadine 10 mg 2 times a day. Also, topical medication with dermatocorticosteroids and emollients was associated. OUTCOME: Under the treatment that was initiated a partial remission of the lesions after 7 days was observed. LESSONS: Our reported case adds to the other findings regarding the association of PR with SARS-CoV-2 infection, in the context of the pandemic, suggesting the need to test patients with PR skin lesions for SARS-CoV-2 infection.

RESUMEN

The chronic use of hydroxyurea (HU) in some oncologic and non-oncologic diseases (psoriasis, sickle cell anemia) can be accompanied by side effects, both systemic and mucocutaneous. The most severe adverse events known in HU therapy are leg ulcers and cutaneous carcinomas. At skin level may also appear: xerosis, persistent pruritus, skin color changes (erythema, hyperpigmentation), cutaneous atrophy. Likewise, oral ulcerations and stomatitis may occur at mucosal level. Hair damage can be expressed through alopecia and nail damage through melanonychia and oncycholysis. First case, a 63-year-old woman with severe psoriasis vulgaris and chronic granulocytic leukemia, with 5 years of HU therapy, was admitted to hospital for submammary and palmoplantar ulcers, superinfected with methicillin-resistant Staphylococcus aureus and Proteus mirabilis. Clinical exam showed that the patient had also cutaneous atrophy, marked palmoplantar xerosis and melanonychia. The second case, a 72-year-old woman with primary thrombocytemia, treated with HU for 3 years, presented with necrotic leg ulcers that were superinfected with Pseudomonas aeruginosa, Enterobacter and E. Coli. The patient associates cellulitis, microbial eczema and xeroderma. In both cases, after HU discontinuation, systemic antibiotics, topical epithelizing agents and emollients, the ulcers had a slow favorable evolution. In our cases, the ulcers appeared after 5, respectively 3 years of HU therapy. It is stressed that in the first case, which had associated psoriasis, after 1 year of 1 g of HU/day, the psoriatic lesions completely disappeared. The severe progression of the ulcers was also favored by the superinfection of the ulcers with 2, respectively, 3 identified germs for which appropriate systemic antibiotics was required.

RESUMEN

Patients that suffer from inflammatory diseases need to pay special attention to nutrition. For this reason, it is very important to change the approach of both health professionals and food industry specialists. There must be a close collaboration, starting from research, the development phase of foods for special nutrition states. Our primary objective was to identify foods or potential dietary ingredients, which efficacy in the treatment of atopic dermatitis had been scientifically demonstrated in vitro, in vivo and clinically. Furthemore, our perspective is presented regarding the research and development of foods for special nutritional states in atopic dermatitis. The PubMed database was analyzed for the period 2018-2020, as well as the European Legislation regarding the appropriate requirements for the composition and knowledge applicable to foods destined for use in special medical purposes. The search criteria were 'chronic dermatitis', 'atopic dermatitis', 'psoriasis', 'alternative treatments', 'natural treatments', 'complementary treatments', 'treatments for chronic dermatitis'. We also looked for undesirable effects or side effects of the foods included in the research in order to treat atopic dermatitis. The results showed that prebiotics, probiotics and certain plant extracts had a high efficacy in controlling inflammation in atopic dermatitis. The food development research for special nutrition states (atopic dermatitis) involves a multidisciplinary team. We started with the establishment of the general objective and continued with the consultation of the PubMed, EMBASE and other databases, and with the in vitro, preclinical and/or clinical determination of the efficacy of new developed foods, that must be protected with patents. The development of foods for special nutrition states represents a solution for improving the quality of life of atopic dermatitis patients.

RESUMEN

RATIONALE: The clinical manifestations of the SARS-CoV-2 infection are mainly respiratory but the virus can cause a variety of symptoms. Dermatological findings are less well-characterized. Data is scarce on their timing, type and correlation with the immune response. PATIENT CONCERNS: We present the case of SARS-CoV-2 infection in a previously healthy woman who presented with respiratory symptoms and developed anosmia, diarrhea, and an erythematous maculo-papular rash on day 15 from symptom onset. DIAGNOSIS: The nasopharyngeal swab tested by real time PCR for COVID-19 was positive. We interpreted this as a viral exanthema likely caused by an immune response to SARS-CoV-2 nucleotides. INTERVENTIONS: She was treated with Hydroxychloroquine, Azithromycin and Lopinavir/Ritonavir, and the rash with topical corticosteroids. OUTCOMES: All symptoms resolved except for anosmia which persisted for 6 weeks. At the 4- and 6-weeks follow-up the IgG titers for SARS-CoV-2 were high. LESSONS: We must consider that SARS-CoV-2 has a multi-organ tropism. In our case, the SARS-CoV-2 infection had lung, nasopharyngeal, neurological, digestive, and skin manifestations. Identifying the different manifestations is useful for understanding the extent of SARS-CoV-2 infection. We not only present a rare manifestation but also suggest that cutaneous manifestations may correlate with immunity.

RESUMEN

RATIONALE: Ecthyma gangrenosum is a cutaneous infection, most commonly occurring during sepsis evolution with Pseudomonas aeruginosa on an immunocompromised background. There have been rare case reports in previously healthy children and rarer are the cases with double etiology. PATIENT CONCERNS: We present the case of a female Caucasian patient, aged 1 year and 8 months, who developed severe sepsis during flu evolution with predominant respiratory and cerebral manifestations. On admission, at skin level, there was noticed a necrotic coccygeal ulceration (with rapid increasing dimensions 0.5/0.5 cm in 24 hours), and with the transformation from a dry necrosis in a sphacelus at the periphery and progression of necrosis in depth. DIAGNOSES: The patient was diagnosed with ecthyma gangrenosum from which Pseudomonsa aeruginosa and Enterococcus faecalis were isolated from the samples that were harvested intraoperatively, decision that was taken considering the appearance of CT scan and the extremely rapid expansion of necrosis. Excisional debridement with necrectomy, lavage, and dressing being performed. The invasion of the fascia was excluded intraoperatively. INTERVENTIONS: Treatment with Meropenem for 14 days was initiated, as well as amikacin and linezolid, the latter being replaced with teicoplanin for 14 days. Red blood cells transfusion, intravenous immunoglobulins, anticonvulsants were also administered. OUTCOMES: Under treatment the evolution was favorable. LESSONS: This case brings into discussion a double etiology of ecthyma gangrenosum, in a previously healthy child that occurred in the evolution of influenza. The evolution was favorable under broad-spectrum antibiotic treatment and surgical excision.

RESUMEN

Melanoma is considered to be the most aggressive skin cancer, with an increasing incidence worldwide. An accurate staging of melanoma is crucial in describing the cancer status, estimating prognosis and deciding the optimal treatment solution. In the present study, melanoma staging highlights the importance of early detection, most of the patients having been diagnosed with advanced stages of this skin cancer. A retrospective study was conducted among 117 patients of the Academic Emergency County Hospital of Sibiu, diagnosed with melanoma between 2007 and 2016. The staging of the patients with melanoma was made using the American Joint Committee on Cancer (AJCC) 7th edition, and reconsidered in the light of the AJCC 8th edition. The results showed that the majority of the cases had distant metastases, 40.17% were diagnosed with stage IV melanoma. 25.65% of the patients were diagnosed with stage III melanoma, having a regional disease. The rest of the cases had localized melanoma (stages I and II, 30.76%), while only 3.42% of them were diagnosed with melanoma in situ, the melanoma type with the greatest chances of survival. Analyzing the Breslow index, it was observed that the most common tumor thickness was 2.1 to 4 mm (34.19%). In conclusion, as the incidence of melanoma increases in Romania, further efforts are needed to improve the early detection of melanoma. There are hopes that with the correct and early diagnosis of melanoma, the mortality rate of this neoplasm will decrease in the future.

RESUMEN

Dear Editor, Eczema is an inflammatory dermatitis mediated by cellular immunity, with an etiology in which environmental, immunological, and genetic factors are involved. Skin inflammation through proinflammatory cytokines creates a favorable environment for microbial antigens and optimal conditions for infection (1). In case of underlying immunosuppression, inflammatory features of dermatitis and superimposed infections are more severe. The presence of minor trauma of the skin in the form of fissures can favor both easier inoculation of some bacterial germs, leading to a dermatitis superinfection, and/or the transcutaneous inoculation of atypical mycobacteria, with a possibility of developing localized types of tuberculous lymphadenitis (TLA). TLA, the localized type of systemic tuberculosis (TB) infection, is the most common form of extra-pulmonary TB in developing countries (2), while lymphadenitis due to atypical mycobacteria is a localized disease, more frequently seen in developed countries (3,4). In tuberculosis, the transmission of Mycobacterium tuberculosis is airborne, while in atypical mycobacterium lymphadenitis transmission can be both airborne or by ingestion or inoculation (5). In both forms of TB, lymphadenopathy evolves towards abscess and presents fibrotic scars or calcifications upon healing (6). A positive diagnosis involves a clinical and epidemiological investigation, a purified protein derivative (PPD) skin test, ultrasound, and CT / MRI of lymph node masses. A lymph node biopsy is used to confirm the diagnosis of TB and PCR, while positive culture confirms the etiology of TB lymphadenitis. The differential diagnosis of TLA is difficult: neoplastic, bacterial, or viral and fungal infections, sarcoidosis, Castleman's disease, drug reactions, etc. (5). TB-induced immunosuppression may favor the development of fungal and bacterial infections, sometimes severe and poorly responsive to treatment. On the other hand, immunosuppressive conditions increase the risk of extra-pulmonary TB (2). A 40-year old woman who had experienced recurrent episodes of dermatitis over the previous 7 years was hospitalized with fever, malaise, and a disseminated erythematous and crusted, exudative, and flexural itching rash (Figure 1). There were fetid, purulent secretions at the conjunctival, auricular, genital, and umbilical areas. The clinical exam also revealed lymphadenopathy syndrome (large, painful submandibular, cervical, and axillar bilateral lymph nodes; an indurated, painful, and adherent left inguinal lymph node of 5-6 cm). Microbial cultures isolated multiple multi-drug-resistant bacteria (SAH-MRSA, Acinetobacter baumannii, Enterococcus faecalis, E. coli, Enterobacter) and Candida albicans in the oral cavity and conjunctival, auricular, nasal, umbilical, and genital areas. The skin biopsy confirmed the diagnosis of dermatitis. PPD skin test was 21 mm. Other tests (HIV and syphilis serology, blood culture, chest X-ray) were negative. Systemic treatment with vancomycin, metronidazole, fluconazole, local antiseptic compresses, and topical corticosteroid ointments was initiated. 2 days after starting the treatment with vancomycin, Redman syndrome occurred (headache, dyspnea, colicky pains, myalgia, rush, fever (39 °C), hypotension (80/40 mmHg), and tachycardia (100 bpm)). This syndrome resolved upon discontinuation of Vancomycin. Further treatment with imipenem/cilastatinand linezolid for 14 days lead to a favorable response with amelioration of the symptoms. Biopsy of the submandibular lymph node raised the suspicion of Castleman's disease; however, due to the overall incomplete clinical picture (no night sweats, no weight reduction, lack of hepatosplenomegaly and peripheral neuropathy), we decided to perform a biopsy of an inguinal lymph node. The histopathological aspect suggested TLA (lymphoid hyperplasia predominantly diffuse, reactive, presenting tuberculous follicles with central caseous necrosis) (Figure 2). A combination of specific antituberculous drugs (isoniazid, rifampicin, pyrazinamide, and ethambutol) for 6 months resolved the lymphadenopathy syndrome with no further recurrence of eczema and skin infections. Certain delayed hypersensitivity mechanisms are involved both in dermatitis and in TB. CD4 lymphocytes are the primary mediators of anti-TB immunity, while proinflammatory cytokines mediate the activation of macrophages involved in controlling bacillary growth (1). In cases of superinfected dermatitis, microbial exotoxins penetrate the skin barrier more easily due to inflammation. Released cytokines (IL-1, TNF, and IL12) favor the expression of E-selectin on endothelial vascular growth factor and on skin lymphocyte antigen expression, with amplification of initial skin inflammation and creating favorable conditions for microbial colonization and infection (7). The common denominator in dermatitis and TB are the circulating immune complexes (up to 56% of TB cases), which are formed by the interaction between an antibody and bacterial antigen (8), which was in this case evidenced by increased levels of IgA and IgG. In our case, the frequent recurrences of infected dermatitis with multiple multi-drug-resistant germs that were poorly responsive to treatment and displayed a severe evolution towards generalization as well as the lymphadenopathy and the persistence of a biological inflammatory syndrome indicated that another immunosuppressive cause could be involved. Isolated bacterial and fungal germs changed the immune status of the patient. The risk of mycobacterium infection was increased by the environment they created and the patient's underlying skin inflammation. The diagnosis of TB lymphadenitis was established by the histopathologist, but in the absence of PCR we could not determine whether the TB infection was caused by Mycobacterium tuberculosis or by atypical mycobacteria. Given that there was no evidence of other sites of TB infection, we conjectured that inoculation of mycobacterium took place at the skin lesion and that an atypical mycobacterium might have contributed to the etiology of the TLA. In our case, the anti-tuberculous drugs and skin infection treatment with follow-up of the side-effects led to complete remission of mycobacterium lymphadenitis, dermatitis, and infectious processes, without relapses. In conclusion, in the present case chronic dermatitis alongside infection with multi-drug-resistant germs led to an immunosuppressive status which, when associated with the presence of multiple skin ports of entry, allowed a mycobacterial infection at the inguinal lymph node level. Inguinal TLA induced severe dermatitis and difficulties in diagnosis and treatment.

RESUMEN

Clear cell acanthoma, firstly described by Degos as "an epidermal tumor with a particular aspect", although quite a rare lesion, raised an important interest because it may be easily confused with other dermatologic lesions, in the absence of a histopathological examination. Its clinical aspect is of a solitary nodule, with a red-brown varying color, with a size of 3 mm to 2 mm, sometimes covered with a thin scall. We present a case of a multiple rare cell acanthoma (seven nodular formations), having a rapid development (about two months) diagnosed in a 71-year-old patient within the lower 1/3 of the right shin.
