Silent sinus syndrome: an underdiagnosed entity.

ABSTRACT: We describe a case of a 33-year-old Caucasian woman with right facial asymmetry and no sinonasal symptoms. She was referred to the ophthalmology department as having right palpebral ptosis. On physical examination, she presented painless enophthalmos and hypoglobus of the right eye. The MRI of the brain only showed sinonasal inflammatory signs of the right maxillary sinus. The CT scan revealed opacification of the right maxillary sinus, with retraction of the sinus walls. We confirmed the diagnosis of silent sinus syndrome. The patient underwent functional endoscopic sinus surgery. One year after surgery, despite clinical and aesthetic improvement, slight enophthalmos remained, but there were no other complications. In our case, the diagnosis of facial asymmetry as ptosis led to an initial imaging investigation to exclude neurological causes. Silent sinus syndrome should be included in the differential diagnosis of facial asymmetry. Despite the clinical suspicion, the diagnosis can only be confirmed by imaging studies.

Silent sinus syndrome (First Case Report, Saudi Arabia with recommendation).

Project description:IntroductionSilent sinus syndrome is a rare disorder that presents a diagnostic challenge, most of the patients with this syndrome present with ophthalmological complaints without any nasal sinus symptoms, and it has a painless course and slow development. The syndrome can be diagnosed clinically and confirmed radiologically, and CT imaging is considered the gold standard for its diagnosis. The classical radiographic findings are opacification and collapse of the sinus walls. Functional endoscopic sinus surgery (FESS) is the standard gold treatment of choice to arrest the progression of the disease.Presentation of caseA case report of a 37-years-old-female who was complaining of severe throbbing pain since 2009, is presented here where the diagnosis of SSS was obtained in 2018, this delay in diagnosing the situation had affected the patient lifestyle tremendously.DiscussionAccordingly, knowledge of the signs and features of SSS can result in an accurate diagnosis. Suspected cases of silent sinus syndrome require prompt ear, nose, and throat referral for consideration of definitive diagnosis and surgical management. Nasal endoscopy and clinical evaluation are also essential for the diagnosis.ConclusionOur recommendation is to consider SSS as a differential diagnosis for patients with spontaneous enophthalmos and hypoglobus, even in the absence of maxillary sinus opacification. Moreover, encourage all the specialists in the medical and the dental field to communicate well together in cases like this.

Jadassohn Lewandowsky Syndrome: A Rare Entity.

Project description:Pachyonychia congenita (PC) is a rare autosomal dominant genodermatosis characterized by hyperkeratosis affecting the nails and palmoplantar areas, oral leucokeratosis, and cystic lesions. It is classically subdivided into two major variants, PC-1 (Jadassohn-Lewandowski syndrome) and PC-2 (Jackson-Lawler syndrome), according to the localization of the mutations in the KRT6A/KRT16 or KRT6B/KRT17 genes, respectively. We report a 9-year-old male patient with a history of thickened, discolored nails, raised spiny skin lesions all over the body since birth with focal plantar keratoderma and absence of natal teeth.

Polyangiitis overlap syndrome: a rare clinical entity.

Project description:Polyangiitis overlap syndrome is a rare clinical entity comprising patients with overlapping features of more than one vasculitis, usually eosinophilic granulomatosis with polyangiitis (EGPA) and granulomatosis with polyangiitis (GPA). Few cases of polyangiitis overlap syndrome have been described in the literature, mostly associated with c-ANCA, anti-proteinase (PR)-3 positivity, a protean clinical picture characterized by vasculitis, eosinophilia and eosinophilic infiltrates in tissues and a favorable response to steroids and immunosuppressant treatments. Herein, we present a case of a 66-year-old woman with nasal obstruction, external nose deformity, sensorineural hearing loss, peripheral blood eosinophilia, high titer anti-PR3 antibodies and lung involvement. Nasal septum biopsies showed inflammatory infiltrate with eosinophilic component; histopathology of the lung demonstrated necrotizing granulomas associated with inflammatory infiltrate composed of numerous neutrophils and some eosinophils. The patient was diagnosed with polyangiitis overlap syndrome and successfully treated with cyclophosphamide. Recognizing this entity is fundamental given the distinct clinical phenotype and outcomes to therapy in the complex scenario of ANCA-associated vasculitides.

Temple-Baraitser Syndrome and Zimmermann-Laband Syndrome: one clinical entity?

Project description:BackgroundKCNH1 encodes a voltage-gated potassium channel that is predominantly expressed in the central nervous system. Mutations in this gene were recently found to be responsible for Temple-Baraitser Syndrome (TMBTS) and Zimmermann-Laband syndrome (ZLS).MethodsHere, we report a new case of TMBTS diagnosed in a Lebanese child. Whole genome sequencing was carried out on DNA samples of the proband and his parents to identify mutations associated with this disease. Sanger sequencing was performed to confirm the presence of detected variants.ResultsWhole genome sequencing revealed three missense mutations in TMBTS patient: c.1042G > A in KCNH1, c.2131 T > C in STK36, and c.726C > A in ZNF517. According to all predictors, mutation in KCNH1 is damaging de novo mutation that results in substitution of Glycine by Arginine, i.e., p.(Gly348Arg). This mutation was already reported in a patient with ZLS that could affect the connecting loop between helices S4-S5 of KCNH1 with a gain of function effect.ConclusionsOur findings demonstrate that KCNH1 mutations cause TMBTS and expand the mutational spectrum of KCNH1 in TMBTS. In addition, all cases of TMBTS were reviewed and compared to ZLS. We suggest that the two syndromes are a continuum and that the variability in the phenotypes is the result of the involvement of genetic modifiers.

Aging-associated sinus arrest and sick sinus syndrome in adult zebrafish.

Project description:Because of its powerful genetics, the adult zebrafish has been increasingly used for studying cardiovascular diseases. Considering its heart rate of ~100 beats per minute at ambient temperature, which is very close to human, we assessed the use of this vertebrate animal for modeling heart rhythm disorders such as sinus arrest (SA) and sick sinus syndrome (SSS). We firstly optimized a protocol to measure electrocardiogram in adult zebrafish. We determined the location of the probes, implemented an open-chest microsurgery procedure, measured the effects of temperature, and determined appropriate anesthesia dose and time. We then proposed an PP interval of more than 1.5 seconds as an arbitrary criterion to define an SA episode in an adult fish at ambient temperature, based on comparison between the current definition of an SA episode in humans and our studies of candidate SA episodes in aged wild-type fish and Tg(SCN5A-D1275N) fish (a fish model for inherited SSS). With this criterion, a subpopulation of about 5% wild-type fish can be considered to have SA episodes, and this percentage significantly increases to about 25% in 3-year-old fish. In response to atropine, this subpopulation has both common SSS phenotypic traits that are shared with the Tg(SCN5A-D1275N) model, such as bradycardia; and unique SSS phenotypic traits, such as increased QRS/P ratio and chronotropic incompetence. In summary, this study defined baseline SA and SSS in adult zebrafish and underscored use of the zebrafish as an alternative model to study aging-associated SSS.

Genetic insight into sick sinus syndrome.

Project description:AimsThe aim of this study was to use human genetics to investigate the pathogenesis of sick sinus syndrome (SSS) and the role of risk factors in its development.Methods and resultsWe performed a genome-wide association study of 6469 SSS cases and 1 000 187 controls from deCODE genetics, the Copenhagen Hospital Biobank, UK Biobank, and the HUNT study. Variants at six loci associated with SSS, a reported missense variant in MYH6, known atrial fibrillation (AF)/electrocardiogram variants at PITX2, ZFHX3, TTN/CCDC141, and SCN10A and a low-frequency (MAF = 1.1-1.8%) missense variant, p.Gly62Cys in KRT8 encoding the intermediate filament protein keratin 8. A full genotypic model best described the p.Gly62Cys association (P = 1.6 × 10-20), with an odds ratio (OR) of 1.44 for heterozygotes and a disproportionally large OR of 13.99 for homozygotes. All the SSS variants increased the risk of pacemaker implantation. Their association with AF varied and p.Gly62Cys was the only variant not associating with any other arrhythmia or cardiovascular disease. We tested 17 exposure phenotypes in polygenic score (PGS) and Mendelian randomization analyses. Only two associated with the risk of SSS in Mendelian randomization, AF, and lower heart rate, suggesting causality. Powerful PGS analyses provided convincing evidence against causal associations for body mass index, cholesterol, triglycerides, and type 2 diabetes (P > 0.05).ConclusionWe report the associations of variants at six loci with SSS, including a missense variant in KRT8 that confers high risk in homozygotes and points to a mechanism specific to SSS development. Mendelian randomization supports a causal role for AF in the development of SSS.
