Project description:PurposeOrbital myiasis is a rare condition. We report a case of massive orbital myiasis (ophthalmomyiasis profunda) arising from nasal myiasis and caused by Chrysomya bezziana in a patient with diabetes.ObservationsA 55-year-old woman presented with massive orbital myiasis from larvae invading the entire orbit, with only a small part of sclera and bulbar conjunctiva left of the ocular structures left unaffected. The patient complained of breathing difficulty and drooping of the left eyelid with no other significant complaints. Computed tomography of paranasal sinuses was performed to determine the extent of intraocular invasion of larvae and the surrounding area that might be involved. The larvae filled the nasal and orbital cavity with bony destruction. The patient had a history of diabetes mellitus with uncontrolled blood sugar.Conclusions and importanceOrbital myiasis is an infestation of any anatomical structure of the orbit with larvae from the order Diptera. To our knowledge, this is the first reported case of massive orbital myiasis arising from nasal myiasis caused by C. bezziana in a patient with diabetes. Eliminating the causative larvae and topical treatment with antibiotics eye ointment therapy improved the patient's symptoms. Epidemiological data are required to improve documentation of the incidence rate of myiasis.

Project description:ObjectiveTo assess feasibility of modified protocol during percutaneous tracheostomy in coronavirus disease 2019 pandemic era.DesignA retrospective review of cohort who underwent percutaneous tracheostomy with modified protocol.SettingsMedical, surgical, and neurologic ICUs.SubjectsPatients admitted in medical, surgical, and neurologic units with prolonged need of mechanical ventilation or inability to liberate from the ventilator.InterventionsA detailed protocol was written. Steps were defined to be performed before apnea and during apnea. A feasibility study of 28 patients was conducted. The key aerosol-generating portions of the procedure were performed with the ventilator switched to standby mode with the patient apneic.Measurements and main resultsData including patient demographics, primary diagnosis, age, body mass index, and duration of apnea time during the tracheostomy were collected. Average ventilator standby time (apnea) during the procedure was 238 seconds (3.96 min) with range 149 seconds (2.48 min) to 340 seconds (5.66 min). Single-use (disposable) bronchoscopes (Ambu A/S [Ballerup, Denmark] or Glidescope [Verathon, Inc., Bothell, WA]) were used during all procedures except in nine. No desaturation events occurred during any procedure.ConclusionsPercutaneous tracheostomy performed with apnea protocol may help minimize aerosolization, reducing risk of exposure of coronavirus disease 2019 to staff. It can be safely performed with portable bronchoscopes to limit staff and minimize the surfaces requiring disinfection post procedure.

Project description:Introduction and importanceMyiasis is an overlooked public health issue, with urogenital myiasis (UGM) being particularly rare, as evidenced by only 59 reported cases worldwide from 1975 to 2017. There is a notable scarcity of cases involving patients with prolonged catheter use related to SCI. The interaction of SCI with the complications associated with indwelling urinary devices is less frequently discussed in prior literature. Up to our best, it is the first case to be reported.Case presentationWe report a case of a 40-year-old male with a spinal cord injury who developed UGM. He presented with multiple white maggots visible at the urethral meatus. He was on a long-term catheter due to urinary retention. There were moving maggots, which were manually removed.Clinical discussionThis case underscores the risk of UGM in patients with urinary catheters, especially in underdeveloped areas where healthcare access may be restricted.ConclusionThere is a critical need for education on UGM for at-risk groups, particularly those with indwelling urogenital devices, to ensure timely diagnosis and treatment and reduce the risk of complications.

Project description:PurposeWe present an unusual case of myiasis involving the orbital cavity.ObservationsOur patient had undergone orbital exenteration one month prior to presentation. Post-operatively, he presented with multiple, highly mobile larvae in the orbital cavity. The species was identified to be Lucilia sericata, known commonly as the blowfly. The maggots were removed mechanically.Conclusion and importanceThe orbital cavity subsequently healed rapidly without sequalae. This raised the question as to whether L. sericata maggots may have had beneficial effects to the healing process.

Project description:BACKGROUND:Myiasis due to Old World screw-worm fly, Chrysomya bezziana, is an important obligate zoonotic disease in the OIE-list of diseases and is found throughout much of Africa, the Indian subcontinent, southeast and east Asia. C. bezziana myiasis causes not only morbidity and death to animals and humans, but also economic losses in the livestock industries. Because of the aggressive and destructive nature of this disease in hosts, we initiated this study to provide a comprehensive understanding of human myiasis caused by C. bezziana. METHODS:We searched the databases in English (PubMed, Embase and African Index Medicus) and Chinese (CNKI, Wanfang, and Duxiu), and international government online reports to 6th February, 2019, to identify studies concerning C. bezziana. Another ten human cases in China and Papua New Guinea that our team had recorded were also included. RESULTS:We retrieved 1,048 reports from which 202 studies were ultimately eligible for inclusion in the present descriptive analyses. Since the first human case due to C. bezziana was reported in 1909, we have summarized 291 cases and found that these cases often occurred in patients with poor hygiene, low socio-economic conditions, old age, and underlying diseases including infections, age-related diseases, and noninfectious chronic diseases. But C. bezziana myiasis appears largely neglected as a serious medical or veterinary condition, with human and animal cases only reported in 16 and 24 countries respectively, despite this fly species being recorded in 44 countries worldwide. CONCLUSION:Our findings indicate that cryptic myiasis cases due to the obligate parasite, C. bezziana, are under-recognized. Through this study on C. bezziana etiology, clinical features, diagnosis, treatment, epidemiology, prevention and control, we call for more vigilance and awareness of the disease from governments, health authorities, clinicians, veterinary workers, nursing homes, and also the general public.

Project description:BackgroundWhile most patients with tuberculosis (TB) can be successfully treated using short-course medical chemotherapy, thoracic surgery is an important adjunctive strategy for many patients with drug-resistant disease. The need for physical, technical and financial resources presents a potential challenge to implementing surgery as a component of treatment for multidrug-resistant TB (MDR-TB) in resource-poor settings. However, a cohort of patients with severe MDR-TB in Lima, Peru underwent surgery as part of their treatment.Methods121 patients underwent pulmonary surgery for drug-resistant tuberculosis between May 1999 and January 2004. Surgery was performed by a team of thoracic surgeons under the Ministry of Health. Patient demographic data, clinical characteristics, surgical procedures and surgical outcomes were studied.ResultsMost of the patients had failed multiple TB regimens and were resistant to a median of seven drugs. The median time of follow-up after surgery was 33 months. 79.3% of patients were culture-positive before surgery, and sustained culture-negative status among survivors was achieved in 74.8% of patients. 63% of those followed up for at least 6 months after surgery were either cured or probably cured. Postoperative complications, observed in 22.6% of patients, were associated with preoperative haemoptysis, vital capacity <50% and low forced expiratory volume in 1 s.ConclusionsThis is one of the largest cohorts with MDR-TB to be treated with surgery, and the first from a resource-poor country. Although surgery is not often considered an option for patients in resource-poor settings, the findings of this study support the argument that adjunctive surgery should be considered an integral component of MDR-TB treatment programmes, even in poor countries such as Peru.

Project description:BackgroundIntestinal myiasis is a type of myiasis resulting from the accidental consumption of Clogmia albipunctata larvae. This type of myiasis generally displays symptoms such as nausea, vomiting, abdominal distention and discomfort, loss of appetite, weight loss, and intermittent diarrhea. It is a rare form of myiasis with relatively scarce literature in Nepal.Case presentationWe report probably the first case of human intestinal myiasis caused by Clogmia albipunctata in Nepal. A 39-year-old nondiabetic female, Brahmin belonging to khas/arya ethnicity presented with complaints of abdominal discomfort, perianal itching, occasional nausea, and vomiting in the outpatient clinic of Sukraraj Tropical and Infectious Disease Hospital, Teku, Kathmandu. With an additional history of the passing of worms in stool, the sample was examined in the microbiology department, which revealed multiple larvae. Macroscopy followed by microscopic examination through wet mount preparation was performed, leading to the morphological identification of larva of Clogmia albipunctata. Diagnosis of a rare human intestinal myiasis was made, and the patient was advised to take ivermectin.ConclusionPersonal hygiene and sanitation, which prevent fly infestation, can help reduce the incidence of the disease.

Project description:BACKGROUND: Chromoblastomycosis is a chronic mycotic infection, most common in the tropics and subtropics, following traumatic fungal implantation. CASE PRESENTATION: A 72 year-old farmer was admitted to Luang Namtha Provincial Hospital, northern Laos, with a growth on the left lower leg which began 1 week after a forefoot leech bite 10 years previously. He presented with a cauliflower-like mass and plaque-like lesions on his lower leg/foot and cellulitis with a purulent tender swelling of his left heel. Twenty-two Chrysomya bezziana larvae were extracted from his heel. PCR of a biopsy of a left lower leg nodule demonstrated Fonsecaea pedrosoi, monophora, or F. nubica. He was successfully treated with long term terbinafin plus itraconazole pulse-therapy and local debridement. CONCLUSIONS: Chromoblastomycosis is reported for the first time from Laos. It carries the danger of bacterial and myiasis superinfection. Leech bites may facilitate infection.

Project description:Background & Aims Primary hepatic neuroendocrine tumors (PHNETs) are rare malignant liver tumors that present diagnostic challenges owing to their rarity and absence of specific clinical features. This study aimed to investigate the characteristics of this rare liver tumor to enhance our understanding of the disease, improve diagnostic accuracy, and explore standardized diagnostic and treatment approaches. Case description During physical examination, two elderly women, aged 64 and 74 years, were found to have liver masses. 18F-FDG Positron Emission Tomography-Computed Tomography (18F-FDG PET-CT) and Ga68-DOTATATE PET-CT scans of both individuals revealed multiple liver masses that were initially suspected to be hepatic neuroendocrine tumors. Subsequent puncture pathology confirmed the diagnosis of neuroendocrine tumors. Furthermore, in Case 1, the tumor was also detected by 18F-FDG PET-CT in the lung, suggesting a metastatic tumor, in conjunction with liver immunohistochemistry and imaging findings. Laboratory tests revealed no significant abnormalities in liver function or autoimmune liver disease indicators, and there was no evidence of viral hepatitis infection. However, partial hepatectomy was not indicated for cases with distant metastasis or multiple space-occupying lesions. Individualized treatment approaches have been developed for such situations. A large portion of the tumor underwent Transarterial Embolization (TAE), and targeted combination chemotherapy or endocrine therapy was administered based on the pathological results. During regular follow-ups a 13 and 12 months, the tumor remained stable. The patients’ quality of life was good, and their psychological well-being was healthy. They led active lifestyles, demonstrated a thorough understanding of their disease and its progression, and actively cooperated during the follow-up process. Conclusion Our findings suggest that a combination of serological, radiological, and immunohistochemical examinations can aid in the diagnosis of PHNET. In addition, we determined that TAE combined with drug therapy could be an effective method for controlling PHNET progression. Regular postoperative follow-ups are important for monitoring the prognosis and tumor progression status of patients with PHNET.
