Pineal cyst-related sleep disorders – a narrative review

The pineal gland is an endocrine gland, which is responsible for the human circadian rhythm, through the regulation of its hormone – melatonin. The most common pathology of a pineal gland is pineal cyst – its population incidence is estimated as 1-23%, depending on the publication. The most common symptoms of a pineal cyst include headache (87%), visual field defects (54%), nausea/vomiting (34%), and dizziness/vertigo (31%). Among the majority of patients with the asymptomatic pineal cyst, the wait-and-see strategy is proper.             According to the newest meta-analyze, the prevalence of sleep disturbances among patients with pineal cyst estimates to be 17%. The results of direct melatonin level measurements in pineal cysts remain unclear. The study focused on sleep disturbances in pediatric patients with pineal cysts and showed a significantly higher score on Sleep Disturbance Scale for Children (SDSC) in the domains of disorders of excessive sleepiness and disorders of initiating and maintaining sleep than the control groups. The impact of lesion on sleep quality correlated with its size.             The pineal cyst may be considered a rare, and potentially reversible, cause of sleep disorders. Nevertheless, according to the present reports (often opposite to each other), this thesis and the mechanism of its occurrence need to be further researched

Energy drinks - product ingredients and their potential toxicity

Energy drinks (NE) are popular stimulants among adolescents and adults. They are commercial, advertised, widely available products that contain increased amounts of caffeine, and are designed to reduce feelings of fatigue in favor of increased mental and physical performance. In addition to caffeine, various ingredients such as vitamins, dyes or substances that impart a certain flavor are added to NEs. Many cases have been described of the harmful effects of NE used alone and in combination with alcohol on the human body: including on the digestive system, central nervous system, cardiovascular system or kidneys. We decided to analyze and compare with each other the composition of NEs from the most popular manufacturers available in most Polish grocery stores. We then briefly described the most important substances available in NE and reviewed the literature on their potential toxicity.  It is reasonable for physicians and teachers to educate young people and their parents about the harmfulness of NE, especially when children are suspected of taking large amounts. Further observations and studies monitoring the harmfulness of NEs are needed, and the drinks themselves should be subject to special surveillance

The Skin as a Mirror of Internal Disease: Comorbidities and Epidemiology of Acne Vulgaris and Adult Female Acne – A Cross-sectional Study and Current State of Knowledge

Acne vulgaris is a common skin condition affecting an increasing number of adults and might be a clue to identifying systemic disease. Objective of this study is assessment of the demographic and clinical characteristic, including comorbidities, of patients with acne with a special focus on adult female acne (AFA). This cross-sectional study analyzed the medical records of 354 patients with acne (323 outpatients and 31 hospitalized). Data concerning patient age, sex, lesions morphology and distribution on body areas, duration of the disease, Body Mass Index, and dermatologic and systemic comorbidities were collected. 61% of all patients were female, 45.37% of women were classified as AFA. The median age of patients with acne was 24 years and 32.5 years for AFA. The face was the most commonly affected area; patients with AFA had lesions on their back than less frequently non-AFA. Predominant eruptions were pustules and papules. 38.7% of patients had concomitant systemic chronic disease, 15.25% had an endocrinologic disorder, and 6.21% had thyroid gland dysfunction. Women with AFA had endocrinologic disorders more frequently (P=0.002), whereas cutaneous signs of hyperandrogenism were observed less frequently than in the non-AFA group (P=0.034). AFA possess distinct clinical features and it should raise suspicion towards possible underlying endocrinologic disturbance

Diagnosis and treatment of obstructive sleep apnoea in patients with pauses in Holter ECG monitoring: case series

Obstructive sleep apnoea (OSA) is a common disease in today’s society and may affect even more of the population in the near future. Ailments and complications of OSA result from a decrease in the muscle tone of the soft palate, which causes shallow breathing or complete apnoea. The consequences of such episodes may be the development of arterial hypertension, the occurrence of cardiac arrhythmias, and also the deterioration of the quality of life. Diagnosis is based on polysomnography in people with suspected OSA. Continuous Positive Airway Pressure (CPAP) therapy is the most effective treatment for OSA. A case series is presented in which patients with OSA risk factors and nocturnal pauses in Holter ECG monitoring (HEM) were diagnosed due to suspected OSA. In the polysomnographic test, severe OSA was diagnosed and CPAP therapy was introduced. Follow-up HEM performed during treatment showed complete resolution or significant reduction in the number and length of nocturnal pauses. Based on the case series, current medical knowledge and guidelines for pacemaker implantation, it was concluded that in the event of pauses in the HEM, the diagnosis of OSA should be considered in each patient, especially if the pauses occur predominantly at night and the patient is at high risk of OSA. Such a procedure may protect the patient from serious complications related to the pacemaker implantation. It should be emphasized, however, that CPAP therapy requires close cooperation of the patient because it brings effects only when it is used for each sleep

Osteopontin Gene Polymorphism and Urinary OPN Excretion in Patients with Immunoglobulin A Nephropathy

Osteopontin (OPN) is a glycoprotein involved in the pathogenesis of multiple autoimmune and inflammatory conditions. However, the association of variants of secreted phosphoprotein 1 gene (SPP1), which encodes OPN, with immunoglobulin A nephropathy (IgAN) has not been examined up to date. Moreover, the role of OPN in disease pathogenesis and clinical manifestations is not fully known. Therefore, the aim of the study was to determine the frequency of four single nucleotide polymorphisms (SNiPs) of SPP1 gene, as well as the urinary OPN excretion in IgAN patients and healthy controls. In total, 58 Caucasian patients with biopsy-proven IgAN and 184 gender-, age-, and ethnically-matched healthy controls were genotyped for rs1126616, rs1126772, rs9138, and rs7687316/rs3841116 polymorphisms by real time polymerase chain reaction (RT-PCR). Urinary OPN concentration was determined by enzyme-linked immunosorbent assay (ELISA) in 58 IgAN patients and 19 controls. SPP1 SNiPs, as well as urinary OPN excretion, were analyzed in relation to their possible associations with the clinicopathological parameters. The frequency of the minor TT/CT genotypes of rs1126616 was significantly higher in IgAN patients compared to controls (P = 0.0217). Similarly, the minor (CC/AC) genotypes and the C allele of rs9138 were more frequent in IgAN patients (P = 0.0425 and P = 0.0112, respectively). Moreover, these two SNiPs were associated with the higher urinary OPN excretion (P < 0.05). These findings suggest that rs1126616, as well as rs9138, may be associated with IgAN development, however future studies in this field are required
