Abstract: Information on asplenic Lyme borreliosis (LB) patients with erythema migrans (EM) is lacking. We compared the course and outcome of 26 EM episodes in 24 post-trauma splenectomized patients (median age 51 years) diagnosed at a single clinical center in Slovenia during 1994–2023 with those of 52 age- and sex-matched patients with EM but with no history of splenectomy. All patients were followed for one year. A comparison of pre-treatment characteristics revealed that EM in splenectomized patients was of shorter duration before diagnosis (4 vs. 8 days, p = 0.034) with a smaller EM diameter (10.5 vs. 14 cm, p = 0.046), and more frequently fulfilled criteria for disseminated LB (3/26, 11.5% vs. 0%, p = 0.034). Treatment failure occurred in 5/26 (19.2%) EM episodes in splenectomized patients versus 0/52 in non-splenectomized patients (p = 0.003). The five treatment failure cases were retreated with antibiotic regimens used to treat EM and had complete resolution of all symptoms/signs. In conclusion, our study showed that splenectomized adult patients with EM differ somewhat in presentation and more often have treatment failure compared with non-splenectomized patients with EM.

Abstract: Članek prikazuje rezultate spremljanja razširjenosti vrste Ips duplicatus (Sahlberg, 1836) v Sloveniji v letu 2025. Uporabili smo 12 režastih pasti tipa Theysohn, ki so bile opremljene s feromonom Dupliwit in ID ECOLURE. Prisotnost vrste smo potrdili na dveh lokacijah, skupno pa smo ujeli 4 osebke. Predstavljena je razprava o pomenu teh najdb v kontekstu razširjenosti, spremljanja in upravljanja dvojnozobega smrekovega lubadarja.

Abstract: The aim of this multicenter study was to evaluate the effectiveness and safety of electrochemotherapy (ECT) for the treatment of mucosal tumors in the head and neck. A total of 71 patients with 84 nodules of different histologies in the oral cavity, pharynx and larynx treated by ECT were evaluated. The data were collected from the InspECT database from 10 participating centers throughout Europe. Primary and recurrent/secondary tumors of different histologies were treated. The overall response rate was 65 %, with a 33 % complete response rate with limited side effects. The response rates of the primary and secondary tumors were not different. However, smaller tumors responded better than tumors larger than 3 cm in diameter. Furthermore, the tumors that were treated with curative intent responded significantly better than those treated with palliative intent. This study demonstrated the feasibility, safety and effectiveness of ECT in a larger cohort of patients with mucosal lesions in the head and neck region. Based on the available data, ECT can be used for the treatment of recurrent and, in some cases, primary mucosal tumors located in the oral cavity, larynx, and pharynx. A better response was obtained in patients with smaller primary tumors treated with curative intent.

Abstract: Background: Pathogenic hemizygous variants in ATP7A most commonly cause Menkes disease or occipital horn syndrome (OHS), whereas ATP7A-related distal hereditary motor neuropathy (dHMN) is rarely reported. Here, we describe two adult brothers with an overlapping dHMN/OHS phenotype caused by a novel ATP7A splice-site variant and review the clinical and genetic features of previously published patients with ATP7Arelated dHMN. Methods: We performed detailed clinical, electrophysiological, and genetic evaluations of both siblings, including exome sequencing and RNA analysis. Additionally, we reviewed the clinical, electrophysiological, and genetic data of previously reported patients with ATP7A-related dHMN. Results: We identified a novel hemizygous ATP7A splice-site variant (NM_000052.7:c.1544-2A>T) in both brothers. The younger brother, who exhibited a more severe phenotype, presented in early childhood with mild global developmental delay, intellectual disability, and chronic diarrhea, while the older brother had childhood-onset chronic diarrhea without cognitive impairment. Both developed distal hereditary motor neuropathy later in life, and imaging revealed occipital horns. Serum copper and ceruloplasmin levels were mildly reduced. RNA sequencing revealed two aberrant transcript isoforms resulting from the splice-site variant, one of which may produce a partially functional protein. Review of previously reported patients shows that ATP7A-related dHMN may occur isolated or with overlapping features of OHS. In patients with the overlapping phenotype, chronic diarrhea was often the first symptom, followed by slowly progressive dHMN. Conclusions: Previously reported ATP7A-related dHMN has been mostly associated with missense variants. Our findings expand the mutational spectrum by identifying a splice-site variant. In patients with an overlapping OHS/dHMN phenotype, diagnosis was typically delayed for decades, suggesting this presentation remains underdiagnosed.
