A tooth in the nasal cavity is an uncommon phenomenon. The exact mechanism is unclear, and patients may present with non-specific nasal symptoms. We encountered a 24-year-old patient with history of cleft palate repair, presenting to us with unilateral nasal discharge not improving with conventional medications. Rigid nasal endoscopy revealed a rhinolith-like foreign body at the floor of the left nasal cavity. Removal of the rhinolith was done under general anesthesia, and it turned out to be an intranasal tooth. Intranasal tooth is often misdiagnosed due to its non-specific symptoms. Detailed dental and oropharyngeal examination as well as imaging studies are essential in diagnosing an intranasal tooth. Early surgical removal is the mainstay of treatment in order to prevent further complications. Patients with unilateral nasal symptoms not responding to conventional treatment require proper ear, nose, and throat (ENT) evaluation to rule out other pathology.
Pseudomembranous tracheitis is a rare life-threatening complication of endotracheal intubation. The exact mechanism of its formation is not well known, and it could mimic crusting or retained secretions in the trachea. We encountered a patient with history of recent intubation, presenting with acute stridor requiring emergency airway stabilization, and was eventually found to have pseudomembranous tracheitis.
Facial nerve tumors constitute about 5% of all facial nerve paralysis. As it is relatively uncommon, it could be misdiagnosed. We encountered an 18-year-old girl who had right facial weakness since the age of four, referred to otorhinolaryngology clinic for further evaluation only when her hearing deteriorated and the facial weakness worsened. Further investigation revealed facial nerve schwannoma. Facial nerve paralysis in the pediatric age group is uncommon and should be examined in detail to rule out other possible etiologies besides Bell's palsy.
Carbuncle is conventionally treated with combinations of intravenous antibiotics and surgical intervention; be it saucerization or incision and drainage. Cosmesis outcome might be unfavorable following surgical intervention, especially when the facial region is involved. Skin grafting surgery may even be needed as a second-stage procedure for a larger wound. We reported a series of three facial carbuncles treated successfully with a new improvised method. Our method includes performing a stab incision prior to draining of pus, coupled with minimal wound debridement, followed by regular irrigation of the wound with antibiotics containing solution. Based on the three cases reported in this article, we conclude that this method is more superior as there is more skin preservation, better patient tolerance, shorter hospital stays, and favorable cosmesis outcome.
Intractable sneezing is a diagnosis of exclusion and is mostly psychogenic. We reported a case of an 11-year-old girl who presented with uncontrollable bouts of sneezing for three weeks, which did not respond to conventional treatment. She was eventually diagnosed to have psychogenic intractable sneezing, which was triggered by an unfortunate family circumstance. She improved with psychotherapy and was discharged well. Literature review on intractable sneezing showed that patients were predominately female teenagers and mostly recovered after psychotherapy. Multidisciplinary team effort especially with a child psychiatrist is important for the treatment and follow-up of these patients. Imaging should also be routinely performed as some had underlying organic causes that presented as intractable sneezing.
Herein, we report a detailed study on creating heterojunction between graphitic carbon nitride (g-C3N4) and bismuth phosphate (BiPO4), enhancing the unpaired free electron mobility. This leads to an accelerated photocatalysis of 2,4-dichlorophenols (2,4-DCPs) under sunlight irradiation. The heterojunction formation was efficaciously conducted via a modest thermal deposition technique. The function of g-C3N4 plays a significant role in generating free electrons under sunlight irradiation. Together, the generated electrons at the g-C3N4 conduction band (CB) are transferred and trapped by the BiPO4 to form active superoxide anion radicals (•O2-). These active radicals will be accountable for the photodegradation of 2,4-DCPs. The synthesized composite characteristics were methodically examined through several chemical and physical studies. Due to the inimitable features of both g-C3N4 and BiPO4, its heterojunction formation, 2.5wt% BiPO4/g-C3N4 achieved complete 2,4-DCP removal (100%) in 90 min under sunlight irradiation. This is due to the presence of g-C3N4 that enhanced electron mobility through the formation of heterojunctions that lengthens the electron-hole pairs' lifetime and maximizes the entire solar spectrum absorption to generate active electrons at the g-C3N4 conduction band. Thus, this formation significantly draws the attention for future environmental remediation, especially in enhancing the entire solar spectrum's harvesting.
