Ureteral duplicity with a left ureterocele: a case report.

An intravesical ureterocele is a rare condition in which a terminal ureter terminates in a cystic dilation of the bladder. We present the case of a 42-year-old female who presented with irritative lower urinary tract symptoms and left lower back pain. Computed tomography (CT) urography revealed ureteral duplication with a ureterocele complicated by upper tract obstruction. Treatment involved endoscopic ureterocelotomy, which successfully relieved symptoms and resolved renal obstruction.

Renal Endometriosis Mimics Renal Cell Carcinoma in a Hypoplastic Kidney: A Case Report.

Renal endometriosis is a rare disorder of cases of urinary tract endometriosis. A 42-year-old woman presented at our outpatient department with an incidental painless mass on her left hypoplastic kidney revealed on an abdominal ultrasound. Abdominal and pelvic examinations revealed no abnormal findings. A computed tomography (CT) scan revealed an anterolateral slightly enhanced left renal mass that measured 1.2 cm in diameter. Furthermore, CT did not reveal any evidence of abdominal or thoracic metastasis. There are a few case reports in the literature of tumors in specimens from patients who underwent nephrectomy for hypoplastic kidneys, but discriminating between benign and malignant masses is difficult unless a nephrectomy is performed. Given the radiological findings and the impaired function of the hypoplastic kidney, laparoscopic radical nephrectomy was recommended. The procedure was performed under general anesthesia without intraoperative or postoperative complications. Microscopic examination revealed several findings consistent with a diagnosis of renal endometriosis. The patient had no symptoms at her last follow-up visit. This case highlights that renal endometriosis can mimic renal cell carcinoma and awareness of this entity should be raised, as it can be asymptomatic, especially when located in a hypoplastic kidney.

Postpartum Guillain-Barré Syndrome: A Case Report and Literature Review.

Guillain-Barré syndrome (GBS) is a rare acute-onset neurological disease with significant morbidity and mortality. The risk of GBS increases after delivery. Labor and delivery presents many possible risk factors for GBS. However, risk factors and prognosis of postpartum GBS remain unclear due to its low incidence. Here, we first present a patient with a history of postpartum GBS who returned for an elective repeat cesarean section (C-section). For her previous delivery, the patient received spinal anesthesia for an urgent C-section. She presented postpartum with jaw pain, facial palsy, respiratory difficulty, progressive bilateral lower extremity weakness, and areflexia. The diagnosis of GBS was confirmed by cerebrospinal fluid (CSF) examination, nerve conduction studies (NCS), and electromyography (EMG). Her symptoms of GBS improved after intravenous immunoglobulin (IVIG) treatment. The patient also had an Escherichia coli-positive urinary tract infection (UTI), which was treated with nitrofurantoin. For her repeat elective C-section, we performed a dural puncture epidural (DPE) anesthesia. After delivery, she was discharged to home uneventfully. She did not report any new neurological symptoms at her three-week follow-up. Here, we also review published cases of postpartum GBS and discuss peripartum anesthetic considerations for patients with GBS, aiming to inform clinical management of postpartum GBS in the future.

Fibroepithelial Polyp of the Vagina With Torsion: A Difficult Diagnosis Based on Clinical and Morphological Findings of the Vaginal Lesion.

Vaginal fibroepithelial polyps are rare benign tumors of the mucosa of the anterior vaginal wall. In extremely rare cases, they may originate from the posterior vaginal wall or be complicated by torsion. Our case concerns a 63-year-old patient who presented to the gynecology outpatient clinic of the General Hospital of Trikala with minor vaginal bleeding. On vaginal examination, a large pedunculated painless hemorrhagic polypoid mass was noticed, originating from the posterior vaginal wall. A torsion of the pedunculated vaginal tumor was suspected, leading to its surgical excision with clear resection margins. Due to extensive tissue necrosis, accurate histological identification of the vaginal neoplasm was not possible. Histological examination excluded vaginal malignancy. Based predominantly on the clinical and morphological features of the vaginal lesion, a diagnosis of vaginal fibroepithelial polyp with torsion was made, acknowledging its limitations. The patient was discharged from the clinic the same afternoon following the surgery. Three months later, no recurrence of the lesion in the vaginal wall was noted. Following the case presentation, this paper provides a brief literature review of this rare entity, focusing on the diagnostic and therapeutic approaches.

COVID-19-Associated Cognitive Biases on Pneumonia Differential Diagnosis.

The coronavirus disease 2019 (COVID-19) pandemic favors cognitive biases such as anchoring and availability biases. The first refers to overvaluing some of the initial information and establishing a diagnosis too early, with resistance to future adjustments. The latter happens when diagnoses more frequently considered are regarded as more common in reality. This case, in which the correct diagnosis was delayed due to these biases, highlights the need to remain aware of them as a means toward timely diagnosis and therapeutic success of pneumonia cases. An 84-year-old woman presented with a mild non-productive cough for two months and fever. She had a history of breast carcinoma treated with radiotherapy in the previous year. Computerized tomography (CT) showed extensive bilateral consolidation foci with ground-glass-opacification areas and bilateral pleural effusion, CO-RADS 3. COVID-19 with bacterial superinfection was suspected and levofloxacin was initiated. Nasopharyngeal swab polymerase chain reaction (PCR) was carried out three times, always negative for SARS-CoV-2. As the patient remained with fever and cough, the antibiotic was escalated to piperacillin/tazobactam and then to meropenem/vancomycin. She underwent bronchofibroscopy and alveolar lavage, with negative SARS-CoV-2 PCR. The re-evaluation CT scan maintained bilateral consolidations, with an aerial bronchogram. The biopsy of pulmonary consolidation allowed the diagnosis of radiation-induced organizing pneumonia. Prednisolone was initiated and achieved clinical remission and radiological improvement. This case highlights the need to remain aware of cognitive biases both when COVID-19 is suspected or ruled out and to consider other diagnoses when there is a lack of therapeutic response.

Functional Recovery in a Patient of Abnormal Left Parieto-Occipital Encephalomalacia With Gliosis-Associated Genu Varum Deformity: A Case Report.

Parieto-occipital encephalomalacia is a macroscopic appearance of the brain with loss of cerebral parenchyma associated with gliosis in the brain's anatomical structures. It occurs because of the liquefaction of brain parenchymal necrosis after cerebral ischemia, infection, and haemorrhages. It is often surrounded by glial cell proliferation in response to damage. Rehabilitation after the manifestation of neurological function must be tailored, and well-coordinated intervention must be formulated. We present a case study of a 77-year-old male with parieto-occipital encephalomalacia associated with genu varum deformity with a complaint of generalized weakness, vertigo, giddiness, and fall with one episode of a seizure attack. Further, bilateral genu varum deformity was noted on the knees. Encephalomalcia is associated with vitamin D deficiency. The physiotherapy rehabilitation consisted of resolving the symptoms of the patient, along with working on strengthening weak muscles of the genu varum deformity of the patient. The proprioceptive neuromuscular facilitation (PNF) method is a popular rehabilitation strategy for regaining motor function. Numerous outcome measures were used to monitor the patient's progress. Outcome measures such as the tone grading scale (TGS), motor assessment scale (MAS), dynamic gait index (DGI), Barthel index (BI), and world health-related quality-of-life (WHORQOL) scales were used. The rehabilitation lasted for six weeks. Tele-rehabilitation also plays a crucial impact in the recovery of patients. By the end of our rehabilitation, the patient significantly improved in performing activities of daily living and improved his quality of life. Tele-rehabilitation helped us stay connected with the patient.

Conservative Management of Maxillary and Mandibular Fractures in a Pediatric Patient With a Modified Open Cap Splint: A Case Report.

Pediatric maxillofacial fractures, which are not very prevalent, account for around 5% of all face injuries. Children under the age of 13 are more susceptible to craniofacial injuries because they have a larger cerebral mass-to-body ratio than adults. The fracture pattern in children does not resemble that of adults, due to which the treatment of pediatric fractures differs from that of adults and can pose substantial difficulties to the pediatric dentist due to many factors, including the complex anatomy of the developing jaw. In this case report, a 5-year-old male patient presented with an injury to the upper and lower jaw. A case was managed with a conservative approach by using a modified open cap splint. A radiographic investigation, including CT brain and face, was done, which revealed the mandibular symphyseal fracture, bilateral condyle, and right Lefort II fracture. A modified open cap splint was fabricated and fixed with circummandibular and circumzygomatic wiring under general anesthesia. After two months, the fractured site showed good healing on orthopantomography (OPG), and satisfactory occlusion was achieved. The patient was kept on monthly follow-ups for up to five months. Treatment guidelines for pediatric maxillary and mandibular fractures are different from those for adults in that most pediatric cases are managed by a conservative approach. Cap splints are a versatile treatment option for juvenile mandibular fractures because they can be used to restore function and aesthetics with minimal morbidity, do not impede jaw growth or the development of dentition, and can be applied to patients of a wider range of ages.

Regional Anesthesia for High-Risk Patients Undergoing Total Knee Arthroplasty: A Case Report.

Total knee arthroplasty (TKA) is a commonly performed surgery for individuals experiencing advanced knee osteoarthritis. Patients undergoing TKA can present with a variety of comorbidities, ranging from the absence of chronic illnesses to the presence of multiple health conditions. The complexity of these comorbidities can pose challenges in carrying out the desired procedure due to the elevated risk profile; this limits the anesthesia modalities that the physician can utilize. Careful consideration of patients' overall health status and personalized anesthesia approaches are crucial to ensure optimal outcomes in this diverse patient population. This case involves an eighty-year-old male with a history of multiple comorbidities who underwent a left TKA. The patient presented a high-risk profile during evaluation, classified as American Society of Anesthesiology (ASA) class IV, which made general and neuraxial anesthesia unfavorable due to high risks. Regional anesthesia was utilized as the sole modality of anesthesia and was successful. This demonstrates that regional anesthesia is a viable option when attending to patients with high risks associated with other anesthesia modalities.

Case report: Environmental adjustment for visual hallucinations in dementia with Lewy bodies based on photo assessment of the living environment.

Background: Visual hallucinations (VH) are associated with visual prediction error in patients with dementia with Lewy bodies (DLB). Given this relationship, environmental adjustments have been suggested, but detailed contents for implementing such environmental adjustments and assessments are poorly documented. This case report preliminarily demonstrates methods for improving VH through our experience with two patients with DLB. We conducted familial interviews to assess the phenomenological features of VH and reviewed photographs of patients' homes to identify the environmental triggers of VH, known as photo assessment of the living environment (PA-LE). Case description: Patient 1 was a 78-year-old woman with a Mini-Mental State Examination (MMSE) score of 11/30. She experienced seeing a stranger, children, and cats at home, which frightened her. VH frequently occurred in the living room and bedroom. The PA-LE showed that several environmental features, such as cushions on a sofa, the pattern on a carpet under a table, and clothing on hangers, were suggestive triggers of VH. Patient 2 was an 88-year-old woman with a MMSE score of 5/30. She had seen strangers, children, and animals at home, some of which were linked to a theft delusion. VH frequently occurred in the living room and bedroom. The PA-LE found that several environmental features, such as clothing on hangers and dolls, were suggestive of VH triggers. Non-pharmacological approaches were tailored to the patients' environmental and psychological states using interviews and PA-LE. This included removing environmental triggers, reducing negative mood, and providing coping strategies for VH. This improved their VH and their caregivers' knowledge of VH. Conclusion: Phenomenological assessments using photographs of the patient's home could identify the environmental triggers associated with VH in patients with DLB and assist in environmental adjustments.

Acute paraquat poisoning in an adolescent with compromised outcome: A case report.

Paraquat, a highly toxic herbicide, accounts for a substantial number of poisoning-related fatalities, primarily prevalent in agricultural regions. The ingestion gives rise to severe complications affecting various organs, including the lungs, gastrointestinal tract, kidneys and liver. This report details the case of an 18-year-old male who had been using cannabis for a year and inadvertently ingested paraquat. He presented at the emergency room exhibiting symptoms of vomiting characterized by hematemesis and regurgitated food particles, along with heartburn, dysphagia and reduced urine output. Given the absence of a specific antidote, the prognosis for paraquat poisoning remains generally unfavourable. Diagnosis relies on circumstantial evidence and clinical manifestations, necessitating a focus on supportive care. Presently, no specific antidote for paraquat poisoning is available. Efforts should concentrate on preventive measures, efficient decontamination strategies and vigilant stabilization protocols in instances of exposure.

Isolated Myocysticercosis of Pectoralis Major: A Rare Case.

Isolated myocysticercosis is a neglected tropical disease and a rare diagnosis, with only a handful of cases being reported in the literature. It is highlighted that recently, it has not only been limited to endemic regions but also persists globally due to widespread migration from endemic regions. We present a case of isolated myocysticercosis of the right pectoralis major without neurological involvement in a non-pork-eater. High-resolution ultrasonography is an effective method of diagnosis. Anti-helmintic drugs are effective treatment options; if not responding, surgical excision is the management of choice. Ultrasound-guided excision is a better treatment modality to prevent complications.

Orthodontic Treatment for Borderline Class III Malocclusion in Adults: Nonextraction Treatment with Anterior Bite Turbo: A Case Report.

Retrusive upper lips, retroclined upper incisors, a shorter midface, and a larger maxillary-mandibular difference are the characteristics of borderline Class III malocclusion. Individuals with borderline Class III malocclusion frequently exhibit certain morphologic, dental, and skeletal traits, which should aid in the diagnosis of the condition. To report the case of a 22-year-old Vietnamese woman who complained of having tense front teeth and lacking confidence when smiling. Medical history did not find anything strange, there was root canal treatment of the first premolar on the left of the upper jaw, asymmetrical concave chin, and right deviation. Orthodontic camouflage treatment using anterior bite turbos in combination with early light short Class III elastics and box elastics was proposed since the patient declined to have orthognathic surgery. In just 10 months of treatment, a Class I molar and canine relationship was created, an anterior crossbite was corrected via mandibular retraction, and severe skeletal malocclusions were successfully treated without orthognathic surgery. Smiling currently showcases the patient's maxillary incisors more prominently, and her lower lip fullness has diminished, giving her a more attractive smile and a significant improvement to her facial profile.

A Rare Case of Calcified Radicular Cyst in Deciduous Tooth.

Radicular cysts (RCs) are one of the most common odontogenic cystic lesions of inflammatory origin. It originates mostly from epithelial residues in periodontal ligaments secondary to inflammation. The pathogenesis involves the activation of epithelial cell rests of Malaseez after physical, chemical, or bacterial injury. Radiographically, it is seen as a well-defined unilocular lesion of size >1.5 cm. RCs are considered rare in the primary dentition, comprising only 0.5-3.3% of the total number of RCs in both primary and permanent dentitions. This is the first case to be reported of a radicular cyst in primary teeth, with dystrophic calcification. How to cite this article: Sunny R, Rag B, Punathil S, et al.

The Enigma Unveiled: Expansile Compound-complex Odontoma in the Anterior Maxilla of a Teenager.

Aim and objective: The objective of this case report is to offer insight into an expansive compound-complex odontoma located in the anterior maxilla of a 15-year-old male. The focus is placed on the importance of early detection and the progressive comprehension of odontomas. Background: Odontomas are common odontogenic lesions that are frequently discovered during examinations for delayed tooth eruption. There are two distinct classifications for odontomas-compound odontomas and complex odontomas. With its own each set of characteristics. A timely diagnosis is critical for avoiding complications. Case description: A male individual aged 15 years exhibited an expansive compound-complex odontoma located in the anterior maxilla. The clinical examination showed delayed tooth eruption and asymptomatic swelling. The radiographic images showed a radiopaque mass with tooth-like structures and radiolucent borders affecting the surrounding dentition. A surgical excision procedure was conducted, followed by a subsequent histopathological examination confirming the diagnosis of compound-complex odontoma. The patient continued orthodontic treatment after a 1-year follow-up without recurrence. Clinical significance: This case emphasizes the importance of regular dental exams in detecting odontomas early. This observation also highlights the growing understanding of odontomas as hamartomatous odontogenic malformations and the challenges of diagnosing them clinically. Additional molecular investigations are required to facilitate the classification and elucidation of genetic factors. How to cite this article: Alhazmi YA.

Angiogenesis Inhibitor Drug-induced Benign Migratory Glossitis in a Patient of Juvenile-onset Recurrent Respiratory Papillomatosis under Maintenance Therapy.

Background: Benign migratory glossitis or geographic tongue is a chronic recurring inflammatory condition of the oral cavity. With its ephemeral characteristics, there has been reported literature showing its association with the administration of certain drugs including angiogenesis inhibitors. The antiangiogenic drugs act by selectively inhibiting the vascular endothelial growth factor (VEGF) signaling. It has been widely used as an adjunct and a maintenance agent for the treatment of various cancers. Aims: This study aims to report probable characteristic oral mucosal changes in a patient with juvenile-onset recurrent respiratory papillomatosis (JORRP) under maintenance therapy with an antiangiogenesis drug. Case description: The patient was presented with a burning sensation on having spicy food. This occurred after the completion of three cycles of bevacizumab infusion. It was associated with the appearance of migratory lesions over the tongue and evolved periods of remission and exacerbation. Clinical examination revealed lesions characteristic of the geographic tongue on the anterior two-thirds of the dorsal surface as well as the lateral surface of the tongue classified as type 2, according to Hume criteria. Oral examination revealed dental caries in relation to 52, 54, 62, 63, 74, and 85 teeth and grossly decayed 64. Topical lignocaine gel was instituted for symptomatic relief of the lesion. Full mouth rehabilitation with preventive and restorative therapeutic interventions was carried out. Clinical significance and conclusion: The documented literature along with this report put forth a probable association of geographic tongue with the use of bevacizumab drugs which requires further detailed studies. These lesions generally require symptomatic treatment with assurance only. The etiology is poorly understood. How to cite this article: Kalra N, Tyagi R, Khatri A, et al.

Prosthetic Management of an Eviscerated Eye of a 13-month-old Patient: A Case Report.

Background: On account of loss of eye following Rubella infection, a 13-month-old baby girl patient required a maxillofacial prosthesis to restore her facial esthetics and social health as she grows. Case presentation: The process of prosthesis fabrication began at the time of enucleation where a conformer was given. Post healing the procedure was completed in a span of 2 days taking adequate trials and cross references for the like-like appearance of the prosthesis. Conclusion: A heat-cure acrylic resin based prosthetic eye was delivered with adequate instructions on the insertion and removal and hygiene maintenance given to the care providers.

The Successful Interdisciplinary Outcome of Blunderbuss Canal with an Open Apex Using MTA under Magnification: A Case Report.

Aim and objective: The present case report aims to describe the nonsurgical management of an anterior tooth with a blunderbuss canal and an open apex using mineral trioxide aggregate (MTA) under magnification. Background: When pulp is traumatized before root formation, it results in pulpal necrosis, due to which dentin and root formation are interrupted. As a result, the canal remains broad due to thin and fragile dentin walls leading to the open apex. Therefore, root canal treatment is a big challenge currently. In such cases, we prefer MTA apexification to form the hard tissue apical barrier, which is a foreseeable treatment and has been used as another advanced method than calcium hydroxide (CaOH2) apexification due to its superior properties. Case description: A novel apexification technique was used by the Departments of Pediatric Dentistry and Conservative Dentistry and Endodontics for MTA placement in the central incisor with respect to 11 of a 9-year-old female patient. MTA was used to form an apical barrier using the micro-apical placement (MAP) system under a dental operating microscope (DOM). Following MTA hard set confirmation, obturation with bioceramic sealer and gutta percha with warm vertical condensation was done, followed by post-endodontic composite restoration. Conclusion: This case describes the nonsurgical management of an open apex using MTA, MAP system, magnification, and bioceramics, which aided in the management of this endodontic enigma.

A rare case of Baker's cysts with hematoma of the lower calf treated with arthroscopic internal drainage combined with intramuscular dissection.

Popliteal cysts, also termed Baker's cysts, are clinically common cystic lesions in the popliteal fossa. Typically, the contents of a ruptured cyst tend to spread into the myofascial interfaces in any direction, most commonly inferomedially or into a palpable superficial position. However, to our knowledge, reports of Baker's cysts dissecting into the deep intermuscular septum of the lower calf are extremely rare. We present here the details of the successful treatment through arthroscopy combined with lower calf incision of a patient who sustained hematoma of the knee and lower calf secondary to Baker's cyst rupture. Given the rarity of this disease in China, we present this case report to improve our understanding of the disease and avoid misdiagnosis and provide evidence for its clinical treatment, management, and prognosis.
