Evaluating dietary considerations in hidradenitis suppurativa: a critical examination of existing knowledge.

Hidradenitis suppurativa (HS) is a chronic condition that can overwhelm patients, and the effectiveness of supplementary dietary treatments remains uncertain. The primary aim of this review is to explore the connection between diet and HS progression. However, it is imperative to note that the evidence supporting a substantial role of the diet in HS remains weak. Dietary alterations alone should not be considered independent solutions for managing HS. Medical therapy continues to be indispensable for adequate treatment. Research indicates that the Mediterranean lifestyle and diet may provide cost-effective and beneficial adjustments when combined with traditional therapies. Conversely, foods with a high glycemic index and dairy could worsen HS symptoms, conceivably through mechanisms linked to insulin resistance and inflammation. Zinc, known for its antioxidant properties, shows promise as an adjunct therapy. Moreover, evidence suggests a connection between vitamin D deficiency and HS severity, although the findings are inconclusive. Brewer's yeast-free diet, B12 supplementation, intermittent fasting, and reducing the intake of refined sugar and dairy merit further investigation. In conclusion, this review highlights the need for additional research because of the lack of standardized reporting of clinical effects in the studies under scrutiny. A deeper exploration of the pathophysiology focusing on dietary modifications and their potential associations with HS severity is essential. Furthermore, it is crucial to recognize that patients' willingness to experiment with new diets makes them vulnerable to fraudulent interventions, highlighting the importance of evidence-based dietary guidance.

Successful infliximab treatment in siblings with Netherton syndrome: Unveiling a novel SPINK5 gene variant and literature review.

Netherton syndrome (NS) is a rare autosomal recessive genodermatosis. In this article, we present two siblings with NS who harbour a novel variant in the SPINK5 gene and were treated with infliximab infusions. Both patients exhibited the characteristic clinical triad of NS, and their whole exome sequencing analysis revealed a homozygous variant, c.1820+53G>A, in the SPINK5 gene. Notably, this is the first documented instance of homozygosity for this particular variant. Despite the absence of a specific treatment, both patients achieved total clearance of the skin lesions, and a significant decrease in total IgE levels was documented.

Peripheral and central smell regions in patients with stroke: an MRI evaluation.

OBJECTIVES: We aimed to determine how odor pathways in the stroke were affected. Measurements were performed by magnetic resonance imaging (MRI). METHODS: Cranial MRI images of 82 adult patients were included. Group 1 was consisted of 41 patients with stroke. The control group (Group 2) was consisted of 41 patients without stroke. In both groups, peripheral (OB volume and olfactory sulcus (OS) depth) and central smell areas (insular gyrus area and corpus amygdala area) were measured by MRI. RESULTS: Peripheral and central smell regions were smaller in the stroke group compared to the control group, whereas right and left side measurements were not different. There were positive correlations between measurements of the peripheral and central smell regions. In older patients with stroke, left OB volume and bilateral OS depths, bilateral insular gyrus areas and bilateral corpus amygdala areas decreased. As the duration of stroke increased, left OB volume decreased. In males with stroke, left OB volume was lower than the females with stroke. Linear regression analysis (backward) showed that in longer stroke duration, OB-volume_R increased and OB volume_L decreased. In older patients, corpus amygdala area_R decreased. In females, OB volume_L increased. CONCLUSION: Both central and peripheral odor pathways were affected, and left OB in the peripheral odor pathways was even more affected in case of longer duration of the stroke. Changes in central and peripheral olfactory pathways in patients with stroke may not be aimed at neuroplasticity and repair, but rather may be a reflection of inflammation and degenerative changes in stroke.

Changes in Peripheral Olfactory Pathways in Rheumatoid Arthritis.

OBJECTIVES: We investigated olfactory bulb (OB) volumes and olfactory sulcus (OS) depths in patients with rheumatoid arthritis (RA). METHODS: In this retrospective study, cranial magnetic resonance images of 68 adult patients were included. Group 1 consisted of 34 adult patients with RA. The control group (group 2) consisted of 34 adult patients without RA. In both groups, peripheral odor pathways (OB volumes and OS depths) were measured by magnetic resonance imaging. RESULTS: Our results showed that the OB volumes of the RA group were significantly lower than those in the control group bilaterally (P < 0.05). In each of the RA and control groups, the OS depth of the right side was found to be significantly higher than those on the left side (P < 0.05). On the left side, OS depth values of RA patients who used biological agents were significantly higher than those RA patients who did not use biological agents (P < 0.05). Correlation tests showed that there were positive correlations between OB volumes and OS depths bilaterally. In older patients with RA, bilateral OS depth values were decreased (P < 0.05). CONCLUSIONS: Our study has shown that the peripheral olfactory pathways in patients with RA can be affected to a degree that is reflected in anatomical measurements. The use of biological agents contributes to the protection of odor functions to a certain extent. The importance of evaluating the sense of smell in patients with RA clinically and radiologically should be emphasized.
