This study aimed to assess the histological changes in the maxillary sinus and its adjacent dental tissues as pulp and periodontal ligament during pregnancy and investigate the role of estrogen hormone in these changes through the detection of estrogen receptors in these tissues. Sixteen adult female rats were used and were allocated into two groups: control non-pregnant (n = 8) and pregnant (n = 8). They were sacrificed and their heads were prepared for histological and immunohistochemical examination for estrogen receptor alpha. Our results revealed that pregnant rats revealed inflammatory changes in the sinus as thick epithelial lining, loss of cilia, swollen goblet cells, intraepithelial and interstitial edema. The lamina propria demonstrated considerable infiltration of inflammatory cells, glandular hyperplasia with vacuolar degeneration, and vascular congestion. Periodontal ligament and pulp revealed hyperemia and vascular congestion. Immunohistochemical examination of estrogen receptor alpha in the maxillary sinus and adjacent dental tissues (Periodontal ligament and pulp) in pregnant rats revealed a significant increase in its expression in all examined tissues. In conclusion, there was an increase in expression of ERα in the sinus mucosa and dental tissues during pregnancy together with slight inflammatory changes in these tissues. Hence, dentists should be aware of the effect of these changes on the pregnant women avoiding teeth extraction due to misdiagnosis of dental, periodontal or sinus pain after exclusion of true pathologies.

Pyoderma gangrenosum (PG) is a rare inflammatory skin disease that is difficult to diagnose. PG may be an extra-intestinal manifestation of ulcerative colitis (UC). In recent times, coronavirus disease (COVID-19) vaccines have caused various adverse cutaneous reactions. However, to the best our knowledge, combinations thereof have not been reported. We encountered a case of PG triggered by COVID-19 vaccination in a patient with UC. A 40-year-old woman developed severe pain and an abscess in the dorsum of the left foot after receiving the first dose of the messenger RNA (mRNA)-based Pfizer/BioNTech BNT162b2 COVID-19 vaccine. Severe painful ulcers with purulent necrosis and gaseous gangrene progressed rapidly along the extensor tendons and muscles to the toes and ankle. Although surgical debridement can worsen PG by triggering pathergy, we nonetheless performed wide debridement including partial extensor tenotomy with abscess drainage to prevent progression to pyogenic ankle arthritis and to rescue the toes. Antibiotics, corticosteroids, and anticoagulants were prescribed during surgical wound management via negative pressure therapy. After the lesion improved, the skin and soft tissue defect were covered using a superficial circumflex iliac artery perforator free flap and a split-thickness skin graft. The patient was satisfied with the foot salvage, and could walk unaided (without a brace or cane) from 8 weeks after the final surgery. PG may be rare even in UC patients, but mRNA-based COVID-19 vaccines may find an immunosuppressive niche. A high level of caution and suspicion of skin manifestations after vaccination is essential.

The peroxisome proliferator-activated receptor gamma (PPARγ), which belongs to the family of nuclear receptors, has been mainly studied as an important factor in metabolic disorders. However, in recent years the potential role of PPARγ in different neurological diseases has been increasingly investigated. Especially, in the search of therapeutic targets for patients with epilepsy the question of the involvement of PPARγ in seizure control has been raised. Epilepsy is a chronic neurological disorder causing a major impact on the psychological, social, and economic conditions of patients and their families, besides the problems of the disease itself. Considering that the world prevalence of epilepsy ranges between 0.5% – 1.0%, this condition is the fourth for importance among the other neurological disorders, following migraine, stroke, and dementia. Among others, temporal lobe epilepsy (TLE) is the most common form of epilepsy in adult patients. About 65% of individuals who receive antiseizure medications (ASMs) experience seizure independence. For those in whom seizures still recur, investigating PPARγ could lead to the development of novel ASMs. This review focuses on the most important findings from recent investigations about the potential intracellular PPARγ-dependent processes behind different compounds that exhibited anti-seizure effects. Additionally, recent clinical investigations are discussed along with the promising results found for PPARγ agonists, and the ketogenic diet (KD) in various rodent models of epilepsy.

Longstanding overt ventriculomegaly in adults (LOVA) is a new form of progressive hydrocephalus characterized by onset in early childhood and gradual progression into adulthood. Patients with LOVA are usually asymptomatic in childhood. The diagnosis of LOVA in adolescence has not been reported.

Pain has globally become an attention problem which causes discomfort by affecting the body as well as the mind. The International association of pain estimated that 1 in 5 patients experiences the pain, i.e. 30% of world population. 19.3% (180-200 million) of the total population in India suffer from chronic pain and its severity appeals early approach of patients to hospitals. Ayurveda being the oldest medical science emphasized its importance and treatment of pain with both pharmacological and non-pharmacological (Parasurgical) methods.

Psychometric tests can provide important information for diagnostics and progression in chronic pain patients. Between 2008 and 2018, the electronic system painDETECT® was used in the outpatient pain clinic of the Hannover Medical School (MHH). The aim of this retrospective study was to evaluate the pain symptomatology data recorded using painDETECT® and the treatment procedures used in the patient cohort examined over a period of 15 months.

Endometriosis is a common chronic gynecological disease defined as the presence of endometrial glands and stroma tissue outside the uterus. Gestrinone is an effective antiestrogen that induces endometrial atrophy and/or amenorrhea. The purpose of this systematic review is to provide an evaluation of safety and effectiveness of gestrinone for the treatment of endometriosis.

Is Long COVID-19 under-diagnosed? The definition of this new condition has received many contributions, and it is still under development as a great variety of symptoms have been associated to it. This study explores the possibility that there are non-diagnosed cases among individuals who have been infected by SARS-CoV-2 and have not been vaccinated. The long-term symptoms identified among a sample 255 individuals have been associated to Long COVID-19 by recent literature. The study relates these symptoms to risk factors and health-related quality of life (HRQoL) negative impacts. The individuals were screened 1 year after discharge to explore its potential relation to Long COVID-19. Patients diagnosed with COVID-19 and discharged from designated hospitals in a Chinese province between January and April 2020 were included in this study. They received computed tomography (CT) scans one month after discharge. One year after discharge, patients were invited to physical examination and interviewed with questionnaire on health-related quality of life (HRQoL) and post-COVID-19 symptoms. Tobit regression and Logistic regression were applied to evaluate the risk factors for health utility value and pain/discomfort and anxiety/depression. One year after discharge, 39.61% patients complained of several of the symptoms associated to Long COVID-19. More than half had abnormal chest CT. Previous studies focused on the post-COVID-19 symptoms and chest CT findings of patients, but few studies have assessed the COVID-19-associated risk factors for health-related quality of life.
