Toxicant exposure and bioaccumulation: a common and potentially reversible cause of cognitive dysfunction and dementia
Authors: Stephen J Genuis, Kasie L Kelln
Journal: Behav Neurol (2015)
MeSH terms: Cognition Disorders / chemically induced, Dementia / chemically induced, Environmental Exposure / adverse effects, Mental Disorders / chemically induced, Case Reports, Aged, Cognition Disorders / diagnosis, Dementia / diagnosis, Humans, Male, Mercury Poisoning / physiopathology

Juxtaposed alongside the ongoing rise in the incidence and prevalence of dementia, is the surge of recent research confirming widespread exposure and bioaccumulation of chemical toxicants. Evidence from sources such as the Centers for Disease Control reveals that most people have accrued varying degrees of assorted toxic pollutants including heavy metals, flame retardants, and pesticide residues within their bodies. It has been well established that many of these toxicants have neurodegenerative as well as neurodevelopmental impact as a result of various pathophysiologic mechanisms including neuronal mitochondrial toxicity and disruption of neurotransmitter regulation. Elimination of stockpiled toxicants from the body may diminish adverse toxicant impact on human biology and allow restoration of normal physiological function. Incorporating a review of medical literature on toxicant exposure and dementia with a case history of a lead-exposed individual diagnosed with dementia, this paper will discuss a much overlooked and potentially widespread cause of declining brain function and dementia.
Rapid progression of a urinary bladder leiomyosarcoma: report of a case
Authors: Toru Yamada, Shingo Nagai, Yusuke Kanimoto
Journal: Case Rep Urol (2011)
MeSH terms: Case Reports

The case we report shows rapid progression and a very poor prognosis only for a month that differs from the clinical course reported in the literature. An 83-year-old man was referred to our hospital for macroscopic hematuria. Computed tomography (CT) revealed a large bladder tumor measuring 4 cm × 3 cm and magnetic resonance imaging revealed extravesical invasion and pelvic wall invasion of the tumors. Chest CT and bone scintigraphy revealed no evidence of distant visceral metastases, and a clinical diagnosis of T4N0M0 was made. Transurethral resection of the bladder tumor (TUR-BT) was performed for histopathological diagnosis 18 days after admission, and no further adjuvant treatment was given. At 15 days after TUR-BT, the patient's clinical status worsened with symptoms of exertional dyspnea. CT showed multiple metastatic lesions in the lung, liver, and retroperitoneal lymphadenopathy. The patient died 2 days later and underwent autopsy. A final histopathological diagnosis of leiomyosarcoma was made based on immunohistochemical staining.
Case Report: Hemangioblastoma- Like Clear Cell Stromal Tumor of the Left Lower Lung
Authors: Xiaowei Zhang, Bifei Huang, Hongquan Jiang, Hangping Wei
Journal: Front Med (Lausanne) (2022)
Keywords: tfe3, yap1, haemangioblastoma-like clear cell stromal tumour, pathology, pulmonary
MeSH terms: Case Reports

Background:
Hemangioblastoma-like clear cell stromal tumor (HLCCST) is a recently reported neoplasm of the lung. Only 13 cases have been reported in four recent studies. Because HLCCST is very rare, it has not been included in the 2021 WHO classification of lung tumors.
Case presentation:
We report a case of HLCCST of the left lower lung in a 40-year-old female who was admitted to our hospital after pulmonary nodules were discovered. A plain chest CT scan showed a nodular high-density shadow measuring approximately 8 mm in diameter in the left lower lung. The lesion had clear borders, uneven internal density, and a low-density central vacuolar area. The left lower lung was partially resected by video-assisted thoracic surgery. Post-operative histopathologic diagnosis "hemangioblastoma-like clear cell stromal tumor" of the left lower lung.
Conclusion:
The HLCCST is an extremely rare tumor and needs long-term follow-up after operation. Clinically, it may be easily confused with other benign and malignant tumors of the lung, and diagnosis is solely determined by histopathologic examination. This case suggests that immunohistochemical CD34 can be a strong positive marker.
Application of interpersonal psychotherapy for late-life depression in China: A case report
Authors: Hua Xu, Diana Koszycki
Journal: Front Psychiatry (2023)
Keywords: china, cultural adaptation, interpersonal psychotherapy, intervention, late-life depression

Objectives:
Interpersonal psychotherapy (IPT) is an effective treatment for late-life depression, but little is known about its acceptability and efficacy in Chinese patients. This case report describes the use of IPT in a depressed elderly Chinese man.
Methods:
The patient was a 79-year-old widower who lives alone in a large city in China. This was his first contact with a mental health specialist. His wife died one ago, and his only child lives in the United States with her husband and children. Due to the COVID-19 pandemic, his daughter could not visit him, and his usual social interactions decreased, leaving him feeling isolated, lonely, and depressed. He was diagnosed with a major depressive episode and initially prescribed venlafaxine. However, he failed to show an adequate response to medication and the side effects were intolerable. He was switched to a low dose of Duloxetine (60 mg) combined with IPT.
Results:
The patient's baseline score on the 17-item Hamilton depression rating scale (HAM-D) was 29, suggesting severe levels of depression. He received 12 sessions of IPT. Role transition was the focus of therapy. Although the patient expressed discomfort in therapy, he developed a good rapport with the therapist and was compliant with treatment. Clinical recovery was achieved at the end of acute IPT treatment (HAM-D score = 1).
Conclusion:
Response to IPT was excellent in this elderly patient, but several points should be noted. First, mental health-related stigma in China can affect treatment engagement. Second, older Chinese are reluctant to speak openly about their personal experiences and feelings. Hence, repeated emphasis on the principles of confidentiality in psychotherapy and forming a strong therapeutic alliance are important. Third, the "empty-nest" household is an emergent phenomenon in China. Helping elderly Chinese navigate changes in traditional Chinese living arrangements and negotiate filial piety with offspring who have moved away are important issues to address in therapy.
Pituitary Adenoma and Hyperprolactinemia Accompanied by Idiopathic Granulomatous Mastitis
Authors: Sebahattin Destek, Vahit Onur Gul, Serkan Ahioglu, Kursat Rahmi Serin
Journal: Case Rep Endocrinol (2017)
MeSH terms: Case Reports

Idiopathic granulomatous mastitis (IGM) is a rare chronic inflammatory disease of the breast, and its etiology remains not fully elucidated. IGM is observed more often in patients with autoimmune disease. Hyperprolactinemia is observed during pregnancy, lactation, and a history of oral contraceptive use. A 39-year-old patient with no history of oral contraceptive use presented with complaints such as redness, pain, and swelling in her left breast. Ultrasound and magnetic resonance imaging (MRI) revealed a suspicious inflamed mass lesion. Core biopsy was performed to exclude breast cancer and to further diagnose. The breast abscess was drained and steroids were given for treatment. In order to monitor any progression during the three months of treatment, hormone levels were routinely examined. Prolactin level was above the reference range, and pituitary MRI revealed a pituitary prolactinoma. After treatment with prolactin inhibitors, IGM also improved with hyperprolactinemia. This report emphasizes attention to hyperprolactinemia in cases of IGM diagnosis and treatment.

Authors: Mehrdad Hasibi, Maral Seyed Ahadi, Hamed Abdollahi, Mehrdad Jafari
Journal: Case Rep Neurol Med (2021)
MeSH terms: Case Reports

Neurologic manifestations are increasingly reported as the coronavirus disease 2019 (COVID-19) pandemic continues. This is a report of a COVID-19 patient with Bell's palsy. Case Summary. A 52-year-old man with fever and malaise was tested positive for COVID-19. After a week, he developed right-sided peripheral facial palsy and was treated with corticosteroids in conjunction with antiviral treatment which resulted in complete recovery. Discussion. Concomitant treatment of corticosteroids and antiviral treatment can decrease morbidity in patients with COVID-19-related Bell's palsy.
Clinical Features of Spinal Cord Hemangioblastoma in a Dog
Authors: Jennifer Michaels, William Thomas, Sylvia Ferguson, Silke Hecht
Journal: Front Vet Sci (2015)
Keywords: dog, hemangioblastoma, intramedullary, spinal cord, tumor
MeSH terms: Case Reports

A 2-year-old male, intact Yorkshire terrier presented with a 1-month history of progressive paraparesis. Neurological examination revealed paraplegia with absent deep pain perception, decreased right pelvic limb withdrawal reflex, and lumbar pain consistent with an L4-S2 neurolocalization. Magnetic resonance imaging (MRI) showed a single, well-demarcated, intramedullary mass centered over the L3-4 disk space. A hemilaminectomy was performed, and the mass was removed en bloc. Histopathological evaluation was consistent with a hemangioblastoma. Follow-up MRI 9 months after surgery showed no evidence of tumor recurrence, and the dog was ambulatory paraparetic at that time. This case is consistent with a previous histopathological report of spinal cord hemangioblastoma in a dog and provides additional clinical information regarding diagnosis, treatment, and outcome associated with this tumor type.
When Local Bone Pain Is Just the Tip of the Iceberg-A Case Report of Three Patients With Chronic Multifocal Recurrent Osteomyelitis and Some Red Flags to Help Make the Diagnosis
Authors: Holly Wobma, Diego Jaramillo, Lisa Imundo
Journal: Front Pediatr (2019)
Keywords: bone pain, chronic non-bacterial osteomyelitis, inflammatory bowel disease, pediatric, pustulosis
MeSH terms: Case Reports

Chronic recurrent multifocal osteomyelitis (CRMO) is an uncommon cause of chronic inflammatory bone pain in children that can be disabling. Often, this diagnosis is considered only after a prolonged workup, leading to frustration for families and unnecessary interventions for patients. Here we describe three cases of CRMO to increase awareness of how it may present. The first patient had a typical presentation of focal bone pain (knee), for which she underwent bone scan (hint of >1 lesion), had a bone biopsy to rule out malignancy, received empiric antibiotics for presumed infection, and finally had whole-body imaging confirming CRMO when symptoms persisted. The second patient had a similar workup, but initially presented with clavicular pain. This location should raise suspicion for CRMO, as it is an uncommon location for infectious osteomyelitis. The third patient presented with delayed growth and right hip pain, and simultaneously developed palmoplantar pustulosis. These secondary findings can also serve as red flags for CRMO, as it has been linked to this skin condition and inflammatory bowel disease. All patients improved on non-steroidal anti-inflammatory (NSAID) medications, methotrexate, and/or tumor necrosis factor (TNF)-α antagonists. By raising awareness of clinical findings suggestive of CRMO, this report may help expedite diagnosis, so patients can be started on anti-inflammatory therapy.
Asthma and pneumonia among children less than five years with acute respiratory symptoms in Mulago Hospital, Uganda: evidence of under-diagnosis of asthma
Authors: Rebecca Nantanda, James K Tumwine, Grace Ndeezi, Marianne S Ostergaard
Journal: PLoS One (2013)
MeSH terms: Asthma / diagnosis, Asthma / epidemiology, Hospitals / statistics & numerical data, Pneumonia / diagnosis, Pneumonia / epidemiology, Research Support, Non-U.S. Gov't, Asthma / drug therapy, Asthma / physiopathology, Clinical Laboratory Techniques, Cough / complications, False Negative Reactions, Female, Humans, Infant, Male, Pneumonia / drug therapy, Pneumonia / physiopathology, Respiration, Uganda / epidemiology

Background:
Pneumonia is considered the major cause of mortality among children with acute respiratory disease in low-income countries but may be over-diagnosed at the cost of under-diagnosing asthma. We report the magnitude of asthma and pneumonia among "under-fives" with cough and difficulty breathing, based on stringent clinical criteria. We also describe the treatment for children with acute respiratory symptoms in Mulago Hospital.
Methods:
We enrolled 614 children aged 2-59 months with cough and difficulty breathing. Interviews, physical examination, blood and radiological investigations were done. We defined asthma according to Global Initiative for Asthma guidelines. Pneumonia was defined according to World Health Organization guidelines, which were modified by including fever and white cell count, C-reactive protein, blood culture and chest x-ray. Children with asthma or bronchiolitis were collectively referred to as "asthma syndrome" due to challenges of differentiating the two conditions in young children. Three pediatricians reviewed each participant's case report post hoc and made a diagnosis according to the study criteria.
Results:
Of the 614 children, 41.2% (95% CI: 37.3-45.2) had asthma syndrome, 27.2% (95% CI: 23.7-30.9) had bacterial pneumonia, 26.5% (95% CI: 23.1-30.2) had viral pneumonia, while 5.1% (95% CI: 3.5-7.1) had other diagnoses including tuberculosis. Only 9.5% of the children with asthma syndrome had been previously diagnosed as asthma. Of the 253 children with asthma syndrome, 95.3% (95% CI: 91.9-97.5) had a prescription for antibiotics, 87.7% (95% CI: 83.1-91.5) for bronchodilators and 43.1% (95% CI: 36.9-49.4) for steroids.
Conclusion:
Although reports indicate that acute respiratory symptoms in children are predominantly due to pneumonia, asthma syndrome contributes a significant proportion. Antibiotics are used irrationally due to misdiagnosis of asthma as pneumonia. There is need for better diagnostic tools for childhood asthma and pneumonia in Uganda.
The involvement of vocal cords in rheumatoid arthritis: a clinical case
Authors: Meryem Eddaoudi, Samira Rostom, Bouchra Amine, Rachid Bahiri
Journal: Pan Afr Med J (2019)
Keywords: rheumatoid arthritis, tracheotomy, vocal cords inflammation
MeSH terms: Arthritis, Rheumatoid / complications, Vocal Cord Paralysis / etiology, Vocal Cords / pathology, Case Reports, Female, Humans, Laryngoscopy / methods, Middle Aged, Tracheotomy, Vocal Cord Paralysis / diagnosis, Vocal Cord Paralysis / surgery

Rheumatoid arthritis rarely involves the cricoarytenoid joint, symptoms of varying severity ranging from foreign body sensation, fullness or tension in the throat, hoarseness, odynophagia, speech or cough pain to stridor and respiratory distress during bilateral paralysis of the vocal cords. We are reporting a case of rheumatoid arthritis with bilateral involvement of the vocal cords. The diagnosis was clinically made and confirmed by endolaryngoscopy, responding to antirheumatic treatment but coming to the stage of permanent tracheotomy.
Case Report and Literature Review Illustrating the Clinical, Endoscopic, Radiologic, and Histopathologic Findings with Prepouch Ileitis after IPAA and Restorative Proctocolectomy for Refractory Ulcerative Colitis
Authors: Christienne Shams, Seifeldin Hakim, Mitual Amin, Mitchell S Cappell
Journal: Case Rep Gastrointest Med (2018)
MeSH terms: Case Reports

Prepouch ileitis (PI) is an uncommon complication of ileal pouch anal anastomosis (IPAA) and restorative proctocolectomy (RPC) for treatment of refractory ulcerative colitis (UC). A case is reported of PI in a 16-year-old girl who presented with severe UC that was initially stabilized with infliximab therapy but re-presented 1 year later with severe UC, refractory to infliximab and corticosteroid therapy, which required IPAA and RPC. Her symptoms resolved postoperatively, but she re-presented 1 year later with 10 loose, bloody, bowel movements/day and involuntary 6-Kg weight-loss. Computerized tomographic enterography showed focal narrowing and mucosal enhancement of the pouch and focal narrowing, abnormal mucosal enhancement, and mural thickening of the prepouch ileum. Pouchoscopy revealed exudates and ulcerations in both the pouch and prepouch ileum up to 50 cm proximal to pouch, as confirmed by histopathology of pouch and ileal biopsies. Capsule endoscopy revealed no small intestinal lesions beyond 50 cm from the pouch. She required antibiotics, hydrocortisone enemas, and eventually azathioprine to control her symptoms. She remains asymptomatic 4 years later while chronically administered azathioprine therapy. Comprehensive literature review demonstrates that this case illustrates the classical clinical, radiologic, endoscopic, and histopathologic findings in PI, a relatively rare syndrome.
Inflammatory myofibroblastic tumor: A rare cause of invagination in adults
Authors: Remzi Kiziltan, Ozkan Yilmaz, Necat Almali, Caghan Peksen
Journal: Pak J Med Sci (2016)
Keywords: adult, ileus, inflammatory myofibroblastic tumor (imt), invagination
MeSH terms: Case Reports

Inflammatory myofibroblastic tumor (IMT) is a distinct pseudosarcomatous lesion arising in the soft tissues and interior organs of children and young adults. It is rarely seen in adults. It was first described in lungs. IMT can occur in any location in the body. However, it is seen most commonly in lungs, intestinal mesentery and liver. Non-mesenteric alimentary tract IMT's are quite rare. The presented case is an ileal IMT that caused small bowel invagination. A 38 year-old male patient presented to the emergency department with the complaint of diffuse abdominal pain, distension and no passage of gas or stools for two days. An abdominal examination revealed distension and tenderness in the abdomen with no guarding or rebound tenderness. Computerized tomography (CT) of the abdomen was ordered. CT revealed an image compatible with invagination of the right lower quadrant of the abdomen and a mass inside the lumen measuring 4x3x3cm. The mass causing invagination was detected during the surgical operation. A segmentary small bowel resection and ileoileal anastomosis was performed. The patient was discharged uneventfully on the postoperative sixth day. The diagnosis of IMT was confirmed histologically and immunochemically.
Peripheral Lung Squamous Carcinoma With ROS1 Rearrangement Sensitive to Crizotinib: A Case Report
Authors: Guangdie Yang, Jie Wang, Yinan Yao, Jun Zhao, Zheyan Yu, Qiqi Gao, Jiani Ye, Wenjiang Ma
Journal: Front Oncol (2021)
Keywords: ros1 rearrangement, atypical imaging manifestation, crizotinib, hypoalbuminemia, lung squamous carcinoma
MeSH terms: Case Reports

ROS1 rearrangements have been identified as driver mutations, accounting for 1-2% of lung adenocarcinoma, but are extremely rare in case of lung squamous cell carcinoma. In this work, we report a lung squamous cell carcinoma in a patient with peripheral lung cancer radiological manifestation, harboring ROS1 rearrangement, with high sensitivity to crizotinib. Our findings suggest that clinicians should pay more attention toward the occurrence of ROS1 rearrangements and the application of crizotinib for lung squamous cell carcinoma treatment.
Maladaptive Denial of Severe Pain and Acute Orthopedic Injuries in a Patient With a Schizoaffective Disorder
Authors: George P Prigatano, Curtis McKnight, Megan Andrews, Jason Caplan
Journal: Front Psychol (2020)
Keywords: denial of illness questionnaire, maladaptive denial, orthopedic injury, schizoaffective disorder, severe pain

Persistent denial of severe and acute pain following orthopedic injuries has not been previously reported. We present a case of a 24-year-old woman with a history of schizoaffective disorder who suffered severe pain secondary to acute orthopedic injuries who insisted, "I am fine! There is nothing wrong with me." Her maladaptive denial resulted in an initial refusal of necessary medical/surgical care, but she eventually accepted the necessary treatments despite her persistent belief she did not need such care. Her verbalizations and behaviors were characterized by active avoidance and angry reactions when a consulting psychiatrist spoke to her regarding her clinical condition. A modified version of the Conscious Avoidance subscale of the Denial of Illness Questionnaire was useful in measuring the severity level of her denial. This case report suggests that the behavioral features of psychological denial appear different from those associated impaired self-awareness secondary to an underlying brain disorder.
Multimodular Assessment of a Traumatic Bone Cyst Overlapped with Apical Periodontitis

Journal: Case Rep Dent (2020)
MeSH terms: Case Reports

Traumatic bone cyst (TBC), a "pseudocyst" that usually affects long bones, is a rare lesion among cystic lesions in the jaws. The most commonly affected site is the posterior mandible. Most of the time, TBC is asymptomatic and discovered during routine radiographic examination. The treatment recommended for TBC is surgical exploration followed by curettage of the bony walls, which also serves as a diagnostic procedure. A 27-year-old Caucasian male with a noncontributory medical history was referred to our department for the endodontic evaluation of the mandibular right first and second molars, which were connected to an extensive asymptomatic osteolytic lesion. A multimodular diagnostic assessment involving CBCT imaging, ultrasound, and histopathologic examination led to a definite diagnosis of a TBC overlapping with apical periodontitis (AP). Subsequently, a multidisciplinary treatment approach was performed, including surgical excision and biopsy of the lesion, endodontic retreatment of the right mandibular first molar, and postsurgical root canal treatment of the second molar. During the follow-up period of five years, the patient was reassessed periodically once a year and showed, in the absence of signs and symptoms, progressive healing of the affected area. The present article reports a case following the CARE guidelines of a TBC combined with AP where a multimodular diagnostic assessment was performed and discusses the possible pathogenetic mechanisms involved in its generation.
Case Report: Management of rectal squamous cell carcinoma - a treatment dilemma
Authors: Nathaniel A Parker, Yasmine Hussein Agha, Charles Scott Buess, Daniel Lalich, Jeremy M Deutsch
Journal: F1000Res (2020)
Keywords: chemoradiotherapy, radiotherapy, rectum, squamous cell carcinoma
MeSH terms: Carcinoma, Squamous Cell / therapy, Rectal Neoplasms / diagnosis, Rectal Neoplasms / therapy, Case Reports, Chemoradiotherapy, Female, Humans, Middle Aged, Neoadjuvant Therapy, Neoplasm Staging

Primary rectal squamous cell carcinoma is rare compared to adenocarcinoma, which is the predominant histologic type most commonly discovered at the time of colorectal carcinoma diagnosis. Due to the infrequent nature of this malignancy, data on tumor pathogenesis and risk factors remains sparse. Moreover, no standardized therapeutic regimen exists. This report describes a case of advanced rectal squamous cell carcinoma diagnosed in a 46-year-old female who initially presented with abdominal pain. Her clinical course was uncomplicated and she responded well to the selected therapy. Much work remains to be accomplished for patients with rectal squamous cell carcinoma.
