A 50-year-old man was admitted to hospital because of
vertigo
for 3 weeks. He was found to have severe hyponatraemia (107 mmol/l), which was rectified with
sodium chloride
infusions. Two weeks later he became agitated with confusion and hallucinations. Within a few hours he went into coma. At that time the serum sodium concentration had again fallen from 132 to 105 mmol/l. Repeated measurement revealed urinary osmolality (558 mosm/l) to be above that of serum (252 mosm/l), pointing to the syndrome of inadequate antidiuretic hormone secretion (SIADH) as the diagnosis. Lung tomography, performed because the patient had two bouts of pneumonia in quick succession, demonstrated enlarged hilar lymph nodes. Bronchoscopy revealed a tumour of about 1.0 cm diameter in the left main bronchus which histologically proved to be a small-cell bronchial carcinoma. Despite chemotherapy the tumour progressed and the SIADH also persisted. The patient died 9 months later of heart failure.

In this study,
Hippospongia communis
marine demosponge skeleton was used as an adsorbent for sodium copper chlorophyllin (SCC). Obtained results indicate the high sorption capacity of this biomaterial with respect to SCC. Batch experiments were performed under different conditions and kinetic and isotherms properties were investigated. Acidic pH and the addition of
sodium chloride
increased SCC adsorption. The experimental data were well described by a pseudo-second order kinetic model. Equilibrium adsorption isotherms were determined and the experimental data were analyzed using both Langmuir and Freundlich isotherms. The effectiveness of the process was confirmed by

Spinning
Nuclear Magnetic Resonance (

C CP/MAS NMR), Fourier transform infrared spectroscopy (FTIR), energy-dispersive X-ray spectroscopy (EDS) and thermogravimetric analysis (TG). This novel SCC-sponge-based functional hybrid material was found to exhibit antimicrobial activity against the gram-positive bacterium
Staphylococcus aureus
.

Gitelman syndrome (GS) is a rare salt-losing tubulopathy caused by an inactivating mutation in the
SLC12A3
gene, encoding the thiazide-sensitive
sodium chloride
cotransporter (NCC). Patients with GS frequently complain of
vertigo
, usually attributed to hypovolemia. Because NCC is also located in the endolymphatic sac, we hypothesized that patients with GS might have vestibular dysfunction. Between April 2013 and September 2016, 20 (22%) out of 90 patients followed at the reference center complained of
vertigo
in the absence of orthostatic hypotension. Sixteen of them were referred to an otology department for investigation of vestibular function. The
vertigo
was of short duration and triggered in half of them by head rotation. Seven patients (44%) had a vestibular syndrome. Vestibular syndrome was defined: (1) clinically, as nystagmus triggered by the head shaking test (
n
= 5); and/or (2) paraclinically, as an abnormal video head impulse test (
n
= 0), abnormal kinetic test (
n
= 4) and/or abnormal bithermal caloric test (
n
= 3). Five patients had associated auditory signs (tinnitus, aural fullness or hearing loss). In conclusion, we found a high frequency of vestibular disorder in GS patients suffering from
vertigo
, suggesting a role of NCC in the inner ear. Referent physicians of these patients should be aware of this extrarenal manifestation that requires specific investigations and treatment.
