“…Headache (91.7%) and visual disturbances (58%) are the most common symptoms, according to the literature [17,18] . According to Danilowicz, 75-100% of patients with visual perspective changes, 54.2% of patients with anterior pituitary dysfunction, and the following syndromes led to panhypopituitarism: adrenocortical adenoma, adrenocortical adenoma, adrenocortical ade decreased libido, cold intolerance, amenorrhea, polyuria, and polydipsia made up 50% of the symptoms [19] . Diabetes insipidus (DI) almost accounts for nearly 50% of PA compared to 10% of pituitary adenoma, indicating that DI aids in diagnosing PA [20] .…”

Object: The study aims to investigate the intractable pituitary abscess (PA) diagnosis and assess the significance of combined intraoperative surgery with postoperative antibiotic treatment. Method: We retrospectively analyzed 19 pituitary abscess patients confirmed by histopathology, all consecutive patients who underwent transsphenoidal surgery (TSS) as pituitary adenomas after accepting comprehensive preoperative inspections, including routine tests, endocrine assay, and imaging examination. Result: Other sellar lesions were misdiagnosed prior to surgery. The favorable prognosis was largely due to surgical and active postoperative antibiotic therapy. Conclusion: Due to the lack of clarity in preoperative diagnosis, typical intraoperative findings and effective antibiotics are more indicative of the correct diagnosis than other tests. When it comes to therapy, optimal surgical and postoperative active antibiotic treatment benefits the PA dilemma.

ObjectiveTo expand our understanding of the pathophysiological mechanisms underlying vestibular neuritis and labyrinthitis by identifying any difference in the vestibulo‐ocular reflex for each semicircular canal.Study DesignRetrospective analysis.SettingThe Department of Otorhinolaryngology – Head and Neck Surgery, Chosun University Hospital, from January 2015 to December 2021.MethodsWe included 23 vestibular neuritis and 27 labyrinthitis patients who had been hospitalized. Pure‐tone audiometry, a bithermal caloric test, and a video head‐impulse test were performed within 5 days of symptom onset.ResultsIn the vestibular neuritis group, mean vestibulo‐ocular reflex gains were decreased to 0.51 in the ipsilesional horizontal canal and 0.55 in anterior canal, leading to marked asymmetry, whereas the gain of the ipsilesional posterior canal was relatively preserved at 0.85. In the labyrinthitis group, the mean vestibulo‐ocular reflex gain was 0.72 in the ipsilesional horizontal canal, 0.73 in the ipsilesional anterior canal, and 0.55 in the ipsilesional posterior canal. We observed statistical differences in the vestibulo‐ocular reflex gain and incidence of corrective saccades on the ipsilesional side in three semicircular canals between the groups (p = .002 for horizontal canal, p = .003 for anterior canal, and p < .001 for posterior canal). The receiver operating characteristic curve showed that pure‐tone audiometry, ipsilesional posterior canal gain, and gain asymmetry of posterior canal were excellent parameters for distinguishing labyrinthitis from vestibular neuritis.ConclusionVestibular neuritis and labyrinthitis patients have different degrees and patterns of video head‐impulse test involvement in the three semicircular canals, suggesting that the two distinct disorders may have different etiologies.

ObjectiveThis study aimed to assess the correlation between the spontaneous nystagmus (SN) and the subjective visual vertical/horizontal (SVV/SVH) among patients with vestibular neuritis (VN) at the different head positions.Study DesignCase‐control study.SettingAffiliated Sixth People's Hospital, Shanghai Jiao Tong University School of Medicine.MethodsThis study evaluated the SVV/SVH in both healthy subjects and patients with VN. These evaluations were performed in 5 different head positions: upright, 45° tilt to the left, 90° tilt to the left, 45° tilt to the right, and 90° tilt to the right. Additionally, the intensity of SN, as measured by slow‐phase velocity, was recorded.ResultsIn patients with VN, a significant correlation was observed between SN and SVV/SVH in an upright position. The intensity of SN was higher when the head was tilted 90° toward the affected side compared to other positions. The SVV/SVH displayed an ipsiversive shift, when the head was tilted toward both the lesion and unaffected sides, exhibiting a contraversive direction. Furthermore, the changes in position‐induced SN were consistent with the displacements of SVV and SVH caused by head tilt.ConclusionThe presence of SN in patients with VN was observed to vary across different head position. These variations could potentially be attributed to the diverse activation patterns of the mechanical properties of otolith organs that are induced by head tilts.
