Background: The aim of this study was to compare eustachian function and blood gas changes with nasal packing (NP) and nasal septal suturing (NSS) after septoplasty. Methods: Eighty patients who have nasal septal deviation and who otherwise are healthy were studied. Forty of these patients had finger glove NPs in their nasal cavities for 48 hours after septoplasty. Another 40 patients had NSS performed after septoplasty. Acoustic tympanometry and pH, PCO ₂ , and PO ₂ analyses of arterial blood were performed preoperatively and 48 hours postoperatively. Results: We observed a statistically significant increase in middle ear pressure (p < 0.001) and a significant reduction of PO ₂ (p < 0.001) and increase of PCO ₂ (p = 0.041) in the NP group but no difference in the NSS group, postoperatively. Conclusion: NSS should be preferred as an alternative to intranasal packing.

OBJECTIVE: Our aim was to investigate the curative role of topical Hypericum perforatum (HP) in a rat model of tympanic membrane perforation in a histopathological manner. MATERIALS AND METHODS: This study was conducted on 30 female Sprague–Dawley rats. An HP extract was prepared as a suspension in pure olive oil. In all rats, the right and left tympanic membranes were perforated by a fine puncture under a microscope. Rats were randomly assigned to three groups. The HP extract was given as drops on a daily basis in Group 1, while olive oil alone was given on a daily basis in Group 2. In Group 3, the rats were allowed spontaneous recovery without any intervention. Three rats from each group were sacrificed on days 7, 14, and 21. Temporal bullae were removed for histopathological examination to evaluate fibroblast proliferation, leukocyte infiltration, neovascularization, and subepithelial thickness and to compare these among the groups. RESULTS: In histopathological examination of the rats from each group on days 7, 14, and 21, there were significant differences in leukocyte infiltration, fibroblast proliferation, and subepithelial thickness. No significant difference was observed in neovascularization among the groups. CONCLUSION: Compared with the spontaneous recovery group, HP was found to be more effective in a wound-healing model of the tympanic membrane. HP may be applied in clinical practice if it is shown to be safe with regard to ototoxicity.

Charcot-Marie-Tooth type 4 (CMT4) is an autosomal recessive severe form of neuropathy with genetic heterogeneity. CMT4B1 is caused by mutations in the myotubularin-related 2 (MTMR2) gene and as a member of the myotubularin family, the MTMR2 protein is crucial for the modulation of membrane trafficking. To enable future clinical trials, we performed a detailed review of the published cases with MTMR2 mutations and describe four novel cases identified through whole-exome sequencing (WES). The four unrelated families harbor novel homozygous mutations in MTMR2 (NM_016156, Family 1: c.1490dupC; p.Phe498IlefsTer2; Family 2: c.1479+1G>A; Family 3: c.1090C>T; p.Arg364Ter; Family 4: c.883C>T; p.Arg295Ter) and present with CMT4B1-related severe early-onset motor and sensory neuropathy, generalized muscle atrophy, facial and bulbar weakness, and pes cavus deformity. The clinical description of the new mutations reported here overlap with previously reported CMT4B1 phenotypes caused by mutations in the phosphatase domain of MTMR2, suggesting that nonsense MTMR2 mutations, which are predicted to result in loss or disruption of the phosphatase domain, are associated with a severe phenotype and loss of independent ambulation by the early twenties. Whereas the few reported missense mutations and also those truncating mutations occurring at the C-terminus after the phosphatase domain cause a rather mild phenotype and patients were still ambulatory above the age 30 years. Charcot-Marie-Tooth neuropathy and Centronuclear Myopathy causing mutations have been shown to occur in proteins involved in membrane remodeling and trafficking pathway mediated by phosphoinositides. Earlier studies have showing the rescue of MTM1 myopathy by MTMR2 overexpression, emphasize the importance of maintaining the phosphoinositides equilibrium and highlight a potential compensatory mechanism amongst members of this pathway. This proved that the regulation of expression of these proteins involved in the membrane remodeling pathway may compensate each other's loss- or gain-of-function mutations by restoring the phosphoinositides equilibrium. This provides a potential therapeutic strategy for neuromuscular diseases resulting from mutations in the membrane remodeling pathway.

In this study, the authors aimed to share their experience with 46 patients who were wounded due to terrorism and war in Somalia. The authors also evaluated the etiological diversity of terror-related and war-related injuries. The study included 46 patients treated at the 150-bed Turkey-Somalia Tertiary Hospital between 2019 and 2021. The authors reviewed medical records including data regarding age, sex, trauma etiology, and type of fracture and trauma. For all patients, surgical technique and plate and screw applications were recorded. The authors also assessed complications and outcomes for the patients. The study included 5 women (10.9%) and 41 men (89.1%). The mean age was 30.36 years. It was found that 2 patients (4.35%) presented to the emergency department with stab injuries, 33 patients with blast injuries from improvised explosive devices (71.73%), and 11 patients with firearm injuries. There were 31 patients with maxillary and mandibular fractures, 17 of which had both maxillary and mandibular fractures. There were 14 patients with maxillary fracture alone, including 3 patients with tripod fracture and 7 patients with inferior and lateral rim fracture. There was a mandibular fracture in 17 patients, including 5 patients with parasymphysis fracture, 7 patients with ramus fracture, and 5 patients with multifocal comminuted fracture. It is a challenging process to treat terror-related injuries in our tertiary hospital in Somalia, where all resources are imported from foreign countries. In such settings, authorities should make protective equipment obligatory to prevent civil and military casualties. Trauma hospitals and experienced trauma surgeons should be available.

The severe acute respiratory syndrome‐coronavirus‐2 pandemic is one of the largest of the recent times and can cause many symptoms including smell and taste disorders. In the literature, smell disorders caused by coronavirus disease-2019 (COVID-19) have been reported within a wide range from 3.2% to 98.3%. A small number of these studies demonstrated smell and taste disorders through objective tests. Our aim in this study was to determine the prevalence of smell and taste disorders in hospitalized patients due to COVID-19 infection. The study was carried out with 100 patients who were positive for real-time polymerase chain reaction and treated at the Kayseri City Hospital, and 100 healthcare worker relatives. We used the Connecticut Chemosensory Clinical Research Center test to evaluate the sense of smell. Sense of taste was evaluated using four different standardized bottles of preparations, and the results were scored according to the patients’ statements. Patient (Group 1) and control (Group 2) groups were compared for age, gender, smell and taste disorders. There were 39 women and 61 men in the patient group, and 40 women and 60 men in the control group. Mean age was 50.2±1.37 (range 21–70) years in Group 1 and 47.6±1.25 (range 18–70) years in Group 2, and there was no significant difference between the two groups. While the rate of smell disorder was 80% in Group 1, we found this rate as 35% in Group 2. Taste disturbance was identified in 38 patients, of whom 16 had mild hypogeusia, 17 had moderate hypogeusia, four had severe hypogeusia, and one patient had ageusia. We found that taste disorder was 38% in Group 1 and 3% in Group 2. Smell and taste dysfunctions are very common symptoms in COVID-19 patients. The results obtained using objective test methods are higher than the rates obtained from patient statements.
