Investigating the concomitance of anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitides and inflammatory bowel disease (IBD).

OBJECTIVE: To assess relationship between Anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis and inflammatory bowel disease (IBD). METHODS: This is a retrospective study design. The patients were identified using a preset criteria of patients who have the diagnosis of ANCA associated vasculitis including a diagnosis of granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) or eosinophilic granulomatosis with polyangiitis (EGPA) with overlapping inflammatory bowel disease (Crohn's disease or ulcerative colitis) in the time period from 01/01/2020 to 08/03/2023. Subsequently data from each patient was collected that will include baseline demographics, disease characteristics, disease activity, treatment information, multiorgan involvement, and pathology findings which were then analyzed. RESULTS: 39 patients were identified that met criteria. 20 patients carried a diagnosis of GPA, 6 had MPA and 4 patients had EGPA. 20 patients with GPA had inflammatory bowel disease, 13 with ulcerative colitis and 6 with Crohn's disease while 1 GPA patient had unspecified inflammatory bowel disease. 4 patients with EGPA had inflammatory bowel disease, 2 with ulcerative colitis and 2 with Crohn's disease. 6 patients with MPA had inflammatory bowel disease, 4 with ulcerative colitis and 2 with Crohn's disease. IBD diagnosis preceded the diagnosis of ANCA vasculitis in 77.8 % of the cases. CONCLUSION: Objective observation and deductions from this study raise the concern for a possible pathogenic association of ANCA associated vasculitis and inflammatory bowel disease and more research is needed to identify any causal association or influence of the two systemic disease on each other.

Bilateral Lumbosacral Plexopathy As the Initial Manifestation of Systemic Sarcoidosis: A Case Report.

Neurosarcoidosis is one of the most relevant involvements in systemic sarcoidosis and can be the initial presentation. Its diagnosis is often considered difficult because of unusual clinical manifestations or diagnostic mimics. The peripheral nervous system is less frequently involved than the central nervous system, although it may also lead to irreversible neurologic impairment. Lumbosacral plexopathy in sarcoidosis is a rare presentation and has been scarcely described in anecdotal case reports and small case series. We describe the case of a 61-year-old female who presented with right inguinal pain, right thigh weakness, and gait limitation, with imaging evidence of bilateral lumbosacral plexopathy as the initial manifestation of systemic sarcoidosis and subsequently developed joint and pulmonary involvement. This case report aims to bring awareness of this involvement as a possible initial manifestation of systemic sarcoidosis and mention key features of the differential diagnosis. Prompt recognition and treatment may prevent neurologic impairment.

Submucosal Epstein-Barr Virus Positive Polymorphic B-cell Lymphoproliferative Disorder of the Larynx: A Case Report.

Epstein-Barr virus (EBV) belongs to the group of human herpes virus and can cause clinical and subclinical infections. Although EBV-related disease presentations are similar, they can lead to oncogenic transformation with various clinical manifestations. A thorough workup with morphology, immunohistochemistry, and molecular studies is crucial for the diagnosis of EBV-positive polymorphic B-cell lymphoproliferative disorder, not otherwise specified (NOS), which is a new entity introduced by International Consensus Classification in 2022. We describe an interesting presentation of EBV-positive polymorphic B-cell lymphoproliferative disorder with laryngeal involvement to bring awareness to this entity and we would like to address the need for more accessible treatment options.

Facial neuropathy with imaging enhancement of the facial nerve: a case report.

A young women developed unilateral facial neuropathy 2 weeks after a motor vehicle collision involving fractures of the skull and mandible. MRI showed contrast enhancement of the facial nerve. We review the literature describing facial neuropathy after trauma and facial nerve enhancement patterns with different causes of facial neuropathy.

Craniocerebral injuries in war against terrorism --- a contemporary series from Pakistan.

OBJECTIVE: Terrorism-related bomb attacks on civilian population have increased dramatically over the last decade. Craniocerebral injuries secondary to improvised explosive devices have not been widely reported in the context of unarmored civilians. This series intends to report the spectrum of these injuries secondary to suicidal and implanted bombs as encountered at the Aga Khan University Hospital, Pakistan (AKUH). Further, a few pertinent management guidelines have also been discussed. METHODS: The hospital database and clinical coding during a 5-year period were examined for head injuries secondary to terrorism-associated blasts. In addition to patient demographics, data analysis for our series included initial Glasgow Coma Scale, presenting neurological complaints, associated non-neurological injuries, management (conservative or operative) to associated complications, and discharge neurological status. RESULTS: A total of 16 patients were included in this series. Among them 9 were victims of suicidal blasts while 7 were exposed to implanted devices. The patients presented with diverse patterns of injury secondary to a variety of shrapnel. A follow-up record was available for 12 of the 16 patients (mean follow-up: 7.8 months), with most patients having no active complaints. CONCLUSION: The results of this series show that civilian victims of suicidal and improvised bombings present with a wide range of neurological symptoms and injury patterns, which often differ from the neurological injuries incurred by military personnel in similar situations, and thereby often require individualized care.

Knowledge of patients' visual experience during cataract surgery: a survey of eye doctors in Karachi, Pakistan.

BACKGROUND: Several recent studies have recommended that ophthalmologists must be aware of the visual sensations (and their associated anxiety/fear) experienced by patients undergoing cataract surgery. We assessed the knowledge of a group of eye doctors in Pakistan regarding these phenomena. METHODS: This was a cross-sectional survey. Eye doctors (ophthalmologists, residents and medical officers) attending the Ophthalmological Society of Pakistan Annual Conference 2011, in Karachi were invited to participate in the study. A self-administered structured questionnaire was used to examine their knowledge of visual sensations and their associated anxiety/fear experienced by patients during cataract surgery. Simple frequencies and proportions were calculated to describe the data. RESULTS: A total of 150 ophthalmologists, residents and medical officers were invited to participate in the study. Of these, 68 (45.3%) responded. The mean age (±SD) of the participants was 42.9 (13.2) years. The proportion of participants who thought that patients could experience visual sensations during cataract surgery under regional anaesthesia was 89.7% and that under topical anaesthesia was 73.5%. The most frequently cited sensations included: light perception, changes in light brightness, movements, instruments and surgeon's hands or fingers.The eye doctors estimated that 38.9% and 64.3% patients would see at least something during cataract surgery under regional anaesthesia and topical anaesthesia, respectively. They also believed that 24.2%-36.9% of patients may experience anxiety/fear as a result of visual sensations during such surgery. Approximately half of the eye doctors did not think that retained vision was a source of fear or anxiety for the patients. While most of them acknowledged the importance of preoperative counselling in helping to alleviate such fear/anxiety, the majority of them did not regularly counsel their patients on what to expect during the surgery. CONCLUSION: Our study reveals that a significant proportion of eye doctors do not have adequate knowledge of the visual phenomenon and their associated anxiety or fear, that patients can experience during cataract surgery. Targeted educational interventions are needed to increase awareness of this phenomenon among eye care professionals.
