Primary central nervous system lymphoma (PCNSL) is a rare and aggressive extra-nodal non-Hodgkin lymphoma (NHL). It must be confined to the brain, eyes, spinal cord or leptomeninges without systemic involvement at the time of diagnosis. Disease confined to the cerebrospinal fluid (CSF) is a rare form of presentation and poses a particular diagnostic challenge. We present the case of an 82-year-old man admitted to hospital because of an acute confusional state, later revealed to be due to PCNSL with exclusive leptomeningeal involvement. The diagnostic process was further impaired (or, perhaps, aided?) by the onset of a COVID-19 outbreak on the ward.

We describe a rare case of haemophagocytic lymphohistiocytosis (HLH) due to ISF, with atypical manifestations. We highlight the need for clinical suspicion for this diagnosis and the importance of timely intervention and support.
Haemophagocytic lymphohistiocytosis is a rare complication of rickettsiosis.An exuberant inflammatory reaction with multisystemic dysfunction should raise suspicion.Cutaneous and neurological manifestations can be serious and extensive.

Each type has a different clinical presentation, aetiology, treatment and prognosis. We report the case of a young woman who presented with cervical lymphadenopathy and a retroperitoneal mass, and was diagnosed with unicentric Castleman disease and pheochromocytoma. We describe the diagnostic steps, the complications that developed, and the importance of the differential diagnosis in the evaluation of these patients.
Castleman disease in an uncommon disease and should be considered in all patients with adenomegalies and systemic symptoms.Pheochromocytoma should not be overlooked in the differential diagnosis of a retroperitoneal mass.It is important that doctors consider these two diagnoses in patients with adenomegalies and a retroperitoneal mass due to the potential harmful impact of a missed diagnosis.

Numerous vaccines have been designed and tested in limited clinical trials in various countries. Among them, the Sputnik V vaccine has shown a relatively safe profile and, to our knowledge, has no associated major side effects. We describe the case of a 40-year-old female healthcare worker who developed severe persistent eczematous lesions on the second day after she received the first dose of the Sputnik vaccine. The eczematous lesions were refractory to an antihistamine and persisted at the 1 month follow-up. Severe persistent eczematous lesions should be viewed as a potential side effect of vaccination with the Sputnik V vaccine. Moreover, a severe allergic reaction to a COVID-2019 vaccine may indicate the vaccine is ineffective in the recipient.
Vaccination against COVID-19 may be accompanied by rare complications.Eczematous lesions can be a side effect of the Sputnik V vaccine.A severe allergic reaction to a COVID-19 vaccine may result in decreased vaccine effectiveness in the recipient.

An increased risk of venous thromboembolism has been described in these patients. We report the case of a 79-year-old woman with a history of polymyalgia rheumatica, who presented with left thoracic pain radiating to the neck and scapula plus temporal headache. She had no changes on physical examination, but work-up tests showed increased D-dimer levels and computed tomography pulmonary angiography revealed signs of a chronic/subacute embolism in the right inferior lobe. Anticoagulation with edoxaban was started after 5-day bridging with enoxaparin. Three weeks after the initial diagnosis the headache still persisted and she developed scalp tenderness. Giant cell arteritis was diagnosed and treated with prednisolone, with complete resolution of symptoms. Extensive diagnostic work-up was performed to identify an alternative cause of pulmonary thromboembolism; however, the investigations were negative. This case supports the hypothesis that this type of vasculitis could be related to the occurrence of pulmonary embolism.
An increased risk of thromboembolism has been associated with giant cell arteritis.Early diagnosis is crucial; however, the role of antiplatelets or anticoagulants is not yet established.

Thymolipoma is a rare benign thymic tumor that arises in the anterior mediastinum. It presents with non-specific symptoms such as chest pain and dyspnea due to compression of the tumor on surrounding structures. In addition, this tumor is associated with paraneoplastic syndromes, including myasthenia gravis. Such a relationship is still not understood and requires investigation.

Investigate the significance of myasthenia gravis in thymolipoma patients.

We present a series of 16 thymolipoma cases from multiple medical centers. Data extraction included demographic, diagnostic, radiological and laboratory, and clinical outcome variables. We also used the modified Osserman score to assess the severity of myasthenia gravis.

Ten patients were males, and six were females; the sample mean age was 39.9 years (SD = 16.7). Upon presentation, 7/16 patients were asymptomatic, 4/16 patients had chest pain, and 2/16 had dyspnea. Seven patients were having myasthenia gravis; they experience generalized weakness (3/7)ds further investigation.
Evaluation of bite force one, two, and four weeks after discharge following treatment of Le Fort I and/or Le Fort II fracture by rigid fixation and mandibulomaxillary fixation.

The aim of this study was to evaluate bite force following treatment of Le Fort I and/or Le Fort II fractures by rigid fixation and mandibulomaxillary fixation at one, two, and four weeks after discharge. This provides valuable results to guide the development of a treatment protocol for Le Fort fractures.

This was a prospective study including 31 patients who underwent followup examination three times after being discharged from hospital. The examination evaluated bite force using a bite force meter in the right molar, left molar, and incisor regions.

One week after discharge, bite forces in the right molar, left molar, and incisor regions were 94.29 ± 58.80 N, 95.42 ± 57.34 N, and 39,94 ± 30,29 N, respectively. Two weeks after discharge, bite forces in the right molar, left molar, and incisor regions were 153.84 ± 89.14 N, 153.00 ± 78.55 N, and 65,9 ± 43.89 N, respectively. Four weeks after discharge, bite forces in the right molar, left molar, and incisor regions were 279.77 ± 95.46 N, 285.00 ± 90,47 N, and 123.42 ± 54.04 N, respectively.

Bite forces in the right molar, left molar, and incisor regions were significantly increased one week, two weeks, and four weeks after discharge. Bite force may be a helpful parameter to confirm the stability of the midface bone after treatment of Le Fort fractures.

We aimed to determine the minimum effective period of mandibulomaxillary fixation after the inadequate internal fixation of Le Fort I or Le Fort II fracture.

The aim of this study was to investigate the stability of the skeleton after the treatment of Le Fort I or Le Fort II fractures by measuring bite forces and to determine the minimum time required for effective mandibulomaxillary fixation following treatment with internal fixation and mandibulomaxillary fixation.

A prospective study was performed to examine the treatment of Le Fort I or Le Fort II fracture in the Department of Maxillofacial Surgery at the National Hospital of Odonto-Stomatology in Ho Chi Minh City, Vietnam. A total of 31 patients were included, with up to 1 month of follow-up after discharge from the hospital. Midface bone stability and the mandibulomaxillary fixation time were evaluated using bite force criteria after 1, 2, and 4 weeks.

Midface bone stability values 1, 2, and 4 weeks after treatment were 87.1%, 100%, and 100%, res can achieve mandibulomaxillary fixation after 2 weeks. For Le Fort I fractures, rigid fixation using plates and screws at zygomaticomaxillary buttresses and canine buttress at three positions can achieve mandibulomaxillary fixation after only 1 week (p = 0.0001).
Based on the available evidence, the COVID-19 virus is transmitted through close contact and droplets, not in the form of airborne transmission (airborne) among humans. People at risk of infection are those who are in close contact with or looking after COVID-19 patients. Preventive and mitigation measures are key in both the healthcare sector and the community. Personal protective equipment (PPE) is mandatory to protect healthcare workers from the new coronavirus, but healthcare workers may have skin damage especially associated with long-term use of PPE.

The main purpose in this study is to forward the effects of PPE and disinfectants on health care workers skin health.

From March to May 2020, self-administered face to face questionnaires were distributed to 200 individuals, consisting of healthcare workes who served in the designated departments of tertiary hospitals Famagusta /Cyprus. The questionnaire included questions about the condition of skin damage and the frequency or duration of several infection-prevention measures.
