ABSTRACT OBJECTIVE AND IMPORTANCE: Primary intracranial melanocytic tumors are rare lesions, sellar ones being even more exceptional. So far, six melanomas and two melanocytomas have been described in an intrasellar and/or suprasellar location. CLINICAL PRESENTATION: We report on the case of a 25-year-old Caucasian woman presenting with a 4-year history of amenorrhea and an intrasellar mass with suprasellar extension suggestive of a pituitary macroadenoma. INTERVENTION: A gross subtotal resection of a hemorrhagic tumor was performed. Histological examination revealed melanin-laden pleomorphic tumor cells that tested positive for HMB-45 and S-100 and negative for cytokeratins, thus demonstrating that the tumor was a melanocytic neoplasm. An extensive workup failed to find evidence of any other primary site. The patient received no further treatment and is alive and well after 24 months of follow-up. CONCLUSION: Primary sellar melanocytic neoplasms are extremely rare lesions and present with few differential diagnoses. Deciding whether the tumor is best classified as a melanocytoma or a melanoma may prove difficult. Wide histological variations in both melanocytomas and melanomas render careful consideration of the clinical, radiological, and gross features essential in distinguishing one from the other.

AbstractMultiple meningeal extradural cysts are extremely rare. The clinical presentation varies from asymptomatic patients to important symptoms due to spinal cord compression. This article reports the case of a girl with multiple meningeal extradural cysts with progressive paraparesis and hypoesthesia on inferior limbs. The MRI showed multiple extradural cysts between C7 and L1. A partial resection was made at the cystis, reflecting a improve at the postoperative follow up of the patient. The management of asymptomatic cases is usually followed up clinical and radiologically. At the management of the symptomatic cases, the resection of the cysts is the most indicated treatment, even for patients with a long-standing history of compression. However the partial removal has as good results as the total one. The authors review the literature and show a subtotal resection of the cysts did not change the evolution of the presentation.

Abstract Oesophago-pleural fistula is an uncommon complication after pneumonectomy, usually related to high morbidity and mortality. Due to its rarity and heterogeneous clinical presentation, its diagnosis and management are challenging issues. Here, we report the case of a patient with a history of pneumonectomy for a tracheal tumour, who developed an asymptomatic oesophago-pleural fistula 7 years after primary surgery. In consideration of the patient’s good clinical status and after verifying the preservation of respiratory and digestive functions, a bold conservative approach was adopted. Five-year follow-up computed tomography did not disclose any sign of recurrence of disease and showed a stable, chronic fistula.

Post-traumatic stress disorder (PTSD) is a prevalent mental disorder marked by psychological and behavioral changes. Currently, there is no consensus of preferred antipsychotics to be used for the treatment of PTSD. We aim to discover whether certain antipsychotics have decreased suicide risk in the PTSD population, as these patients may be at higher risk. A total of 38,807 patients were identified with a diagnosis of PTSD through the ICD9 or ICD10 codes from January 2004 to October 2019. An emulation of randomized clinical trials was conducted to compare the outcomes of suicide-related events (SREs) among PTSD patients who ever used one of eight individual antipsychotics after the diagnosis of PTSD. Exclusion criteria included patients with a history of SREs and a previous history of antipsychotic use within one year before enrollment. Eligible individuals were assigned to a treatment group according to the antipsychotic initiated and followed until stopping current treatment, switching to another same class of drugs, death, or loss to follow up. The primary outcome was to identify the frequency of SREs associated with each antipsychotic. SREs were defined as ideation, attempts, and death by suicide. Pooled logistic regression methods with the Firth option were conducted to compare two drugs for their outcomes using SAS version 9.4 (SAS Institute, Cary, NC, USA). The results were adjusted for baseline characteristics and post-baseline, time-varying confounders. A total of 5294 patients were eligible for enrollment with an average follow up of 7.86 months. A total of 157 SREs were recorded throughout this study. Lurasidone showed a statistically significant decrease in SREs when compared head to head to almost all the other antipsychotics: aripiprazole, haloperidol, olanzapine, quetiapine, risperidone, and ziprasidone (p < 0.0001 and false discovery rate-adjusted p value < 0.0004). In addition, olanzapine was associated with higher SREs than quetiapine and risperidone, and ziprasidone was associated with higher SREs than risperidone. The results of this study suggest that certain antipsychotics may put individuals within the PTSD population at an increased risk of SREs, and that careful consideration may need to be taken when prescribed.

Abstract One of the diagnostic criteria of essential thrombocythemia (ET) is the absence of the Philadelphia chromosome (Ph-neg). On the molecular level, Ph-neg ET patients may carry BCR-ABL transcript. The natural history of BCR-ABL positive Ph-neg ET patients is undetermined. We examined the BCR-ABL status by reverse transcriptase two-step nested polymerase chain reaction in bone marrow aspirates of 25 Ph-neg ET patients. We found 12 BCR-ABL positive and 13 BCR-ABL negative patients in the study group. The comparison showed that the two groups had similar clinical and laboratory characteristics, except for a significant increased patients' age and decreased polymorphonuclear cell count in the BCR-ABL positive group. During a median follow-up of 20 and 22.5 months for the BCR-ABL negative and positive groups, respectively, there was neither blastic transformation nor unrelated death in both groups. We conclude that it is important to look for BCR-ABL transcript in Ph-neg ET patients and to follow them closely to investigate the nature of this translocation in this group of patients.

AbstractMetastases to pituitary adenomas are very rare. From the 20 cases found in the literature, none originated from a cutaneous melanoma. We present the case of a 67-year-old man with a history of transcranial approach to treat a pituitary macroadenoma followed by adjuvant radiotherapy. Fifteen years later, he presented a dorsal nodular melanoma, and three years after that, he developed symptoms of pituitary apoplexy. He was submitted to transsphenoidal surgery, and the histology result revealed metastasis of the melanoma into a pituitary adenoma.The similarity in the clinical presentation of the two entities—pituitary apoplexy and metastasis of the melanoma into a pituitary adenoma—and the rarity of this type of metastization alert to challenges in the differential diagnosis that may confound the neurosurgeon's decision.

Intracranial intravascular papillary endothelial hyperplasia (IPEH) is very rare, and to our knowledge long-term follow-up results have not been previously published. An 11-year-old boy presented with a 6-month history of progressive visual impairment in the right eye. Magnetic resonance imaging revealed a well-enhanced, large parasellar mass involving the cavernous sinus, right frontal skull base, and ethmoid and sphenoid sinuses. Frontotemporal craniotomy and subtotal resection were performed, and the diagnosis of IPEH was confirmed. The mass increased in size during the following 3 months. A second operation was performed via frontotemporal craniotomy combined with a transsphenoidal approach, and gross-total resection of the tumor was achieved. Adjuvant radiotherapy (5040 cGy) and chemotherapy with interferon were administered. The patient's visual symptoms improved, and there was no recurrence during a 13-year follow-up period. The results of this case indicate that intracranial IPEH can recur with subtotal resection; however, optimal resection with multimodal adjuvant treatment can control the disease for many years, if not permanently.

Background: The objective of the study was to study clinical presentation, mode of insertion, and management of intravesical foreign bodies in patients treated at our hospital.Methods: This was a retrospective study conducted between January 2018 to June 2019. Six patients underwent treatment for urinary bladder foreign body at Lokmanya Tilak Municipal Medical College and Sion Hospital, Mumbai, Maharashtra, India. Medical records were analyzed retrospectively with regard to nature of foreign body, each patient’s clinical presentation, the mode of insertion and how the foreign was managed.Results: A total of six foreign bodies were retrieved from patients’ urinary bladders. The patients range in age from 28 to 65 years (mean age was 45 years). The Clinical presentation includes Lower urinary tract symptoms. Four patients were male and two were female. Circumstance of insertion was iatrogenic in 5 patients and self-insertion in 1 patient. Five patients were treated endoscopically (cystoscopy retrieval with or without cystolithotrity) and one patient with supra pubic cystostomy. Post-operative hospital stay was of 1 to 2 days. Mean follow up period was 3 months. Psychiatric referral and counseling were done in patients with history of self-insertion of foreign body in urinary bladder.Conclusions: Foreign body in the urinary bladder remain a challenge to the urologist. Removal of the foreign body without injury to the urinary bladder or the urethra gives good outcome.

Introduction. COVID-19 is responsible for the current global pandemic. Globally, over 15 million people are currently infected, and just over 600,000 have died due to being infected. It is known that people with chronic illnesses and compromised immune systems can develop more severe clinical presentation. Tuberculosis is still one of the biggest epidemiological problems worldwide. Both of these diseases can be misdiagnosed and can manifest in a similar way. We will present a case study of a patient who was initially treated as a COVID-19 infection, with Tuberculosis being diagnosed later on. The recovery began only after being treated for both diseases simultaneously. Case report. The patient is a 27-year-old male, non-smoker, with no history of any significant diseases. He presented with fever, fatigue and hemoptysis. Computed tomography pulmoangiography had shown massive consolidations and excavations, which could be caused by COVID-19. Despite being treated for COVID-19, there was no clinical improvement. On the follow-up chest X-radiograohy, beside signs of COVID-19, there were also changes that could indicate Tuberculosis. Tuberculosis was detected in sputum, using PCR and Mycobacteria Growth Indicator Tube, and only after being treated for both diseases did his condition improve. Conclusion. There are a few reported cases of COVID-19 and Tuberculosis coinfections, and we believe that there are many more patients with this coinfection being unrecognized.

Abstract Background The initial episode of angioedema in children can be potential life-threatening due to the lack of prompt identification and treatment. We aimed to analyze the factors predicting the severity and outcomes of the first attack of acute angioedema in children. Methods This was a retrospective study with 406 children (< 18 years) who presented in the emergency department (ED) with an initial episode of acute angioedema and who had subsequent follow-up visits in the out-patient department from January 2008 to December 2014. The severity of the acute angioedema was categorized as severe (requiring hospital admission), moderate (requiring a stay in the short-term pediatric observation unit [POU]), or mild (discharged directly from the ED). The associations among the disease severity, patient demographics and clinical presentation were analyzed. Result In total, 109 (26.8%) children had severe angioedema, and the majority of those children were male (65.1%). Most of the children were of preschool age (56.4%), and only 6.4% were adolescents. The co-occurrence of pyrexia or urticaria, etiologies of the angioedema related to medications or infections, the presence of respiratory symptoms, and a history of allergies (asthma, allergic rhinitis) were predictors of severe angioedema (all p < 0.05). Finally, the duration of angioedema was significantly shorter in children who had received short-term POU treatment (2.1 ± 1.1 days) than in those who discharged from ED directly (2.3 ± 1.4 days) and admitted to the hospital (3.5 ± 2.0 days) (p < 0.001). Conclusion The co-occurrence of pyrexia or urticaria, etiologies related to medications or infections, the presence of respiratory symptoms, and a history of allergies were predictors of severe angioedema. More importantly, short-term POU observation and prompt treatment might be benefit for patients who did not require hospital admission.
