Atypical perforated appendicitis secondary to schistosomiasis: a rare case report.

Introduction: Schistosomiasis is the second most common parasite disease after malaria and a rare cause of appendicitis. It has been well-documented in the literature that schistosomiasis infection can have several multisystem effects. The unusual condition known as schistosomal appendicitis was initially described by Turner. Case presentation: We present a 48-year-old man with perforated appendicitis and schistosomiasis-like radiological findings. An appendectomy was performed, and schistosomiasis was confirmed by a histological study of the excised appendix. Praziquantel was administered in a single dosage. Conclusion: Although schistosomiasis is a rare cause of appendicitis and is very prevalent in developing nations, it should be considered when managing the condition. Anti-shistosoma drugs, which are not frequently used in post-appendectomy cases, should also be considered in the management.

Aerobic granular sludge development using diatomite for low-strength wastewater treatment.

This paper presents an assessment of the start-up performance of aerobic granular sludge (AGS) for the treatment of low-strength (chemical oxygen demand, COD < 200 mg/L) domestic wastewater by the application of a diatomite carrier. The feasibility was evaluated in terms of the start-up period and stability of the aerobic granules as well as COD and phosphate removal efficiencies. A single pilot-scale sequencing batch reactor (SBR) was used and operated separately for the control granulation and granulation with diatomite. Complete granulation (granulation rate ≥ 90%) was achieved within 20 days for the case of diatomite with an average influent COD concentration of 184 mg/L. In comparison, control granulation required 85 days to accomplish the same feat with a higher average influent COD concentration (253 mg/L). The presence of diatomite solidifies the core of the granules and enhances physical stability. AGS with diatomite recorded the strength and sludge volume index of 18 IC and 53 mL/g suspended solids (SS) which is superior to control AGS without diatomite (19.3 IC, 81 mL/g SS). Quick start-up and achievement of stable granules lead to an efficient COD (89%) and phosphate removal (74%) in 50 days of bioreactor operation. Interestingly, this study revealed that diatomite has some special mechanism in enhancing the removal of both COD and phosphate. Also, diatomite has a significant influence on microbial diversity. The result of this research implies that the advanced development of granular sludge by using diatomite can provide promising low-strength wastewater treatment.

Spontaneous expulsion of 10 years retained intrathoracic foreign body (bullet) from left main bronchus: A case report.

A foreign body lodged in the tracheobronchial tree is a serious and common medical emergency that can have serious and perhaps lethal consequences. A few cases have been reported in the literature for the last century with gunshot wounds to the chest that were handled non-operatively and finally expelled the bullet on their own. We present a case of a hemodynamically stable 50-year-old male with a 10-year-old penetrating thoracic gunshot wound, with the bullet found in the left main bronchus on computed tomography (CT) scan upon admission. Further examination found no evident erosive injuries, such as hemoptysis, but he did have empyema and required a thoracotomy for decortication. Shortly after discharge, he coughed out a bullet into the floor, which is why our case is so intriguing. This case demonstrated that a bronchial foreign body is seldom spontaneously expelled.

Intra-abdominal mass with empty scrotum in adult male revealed as testicular seminoma: A case report.

During fatal development, the testes grow in the abdomen and descend into the scrotal sac. It can be stopped at any point along its path (cryptorchidism) or migrate to an atypical side (ectopic testis). A 47-year-old man from Somalia's lower Shabelle region was presented to the urology OPD, He had a history of non-tender abdominal mass for the previous four months, An examination revealed a mass in his abdomen that was firm, non-tender, and immobile, an abdominal ultrasound and a contrast enhanced CT abdomen showed a 15-cm heterogeneous bean-shaped mass above the bladder. After patient counseling and informed written consent, a laparotomy was done to remove the tumor. A seminoma of the undescended testis was identified during a histological examination. An intra-abdominal mass with empty scrotum should raise concerns about an intra-abdominal testicular tumor. To prevent/early discover these types of tumors, cryptorchidism should be treated at a young age, particularly before to the first year.

A case report of medically managed esophageal fistula due to complicated esophageal tuberculosis.

INTRODUCTION AND IMPORTANCE: Esophageal TB is a relatively uncommon condition. Mostly, the esophagus can be affected by tuberculosis through direct spread or from mediastinal nodes (rarely from the lungs or bloodstream). The most common symptom is dysphagia, and the diagnosis is confirmed by histology. If left untreated, esophageal tuberculosis can result in bleeding, perforation, fistula formation, aspiration pneumonia, lethal hematemesis, traction diverticula, and esophageal strictures. CASE PRESENTATION: This is a rare case report of an esophageal fistula caused by tuberculosis in a patient presenting with a cough on eating and weight loss. The patient was subjected to upper gastrointestinal endoscopy, which revealed a cervical esophagus fistula 20 cm from the upper central incisors. Histopathology revealed inflammatory lesions with epithelioid granulomas (granulomatous disease). A mycobacterium sputum examination was performed; the smear was negative. The patient was managed conservatively with anti-tuberculosis treatment (ATT). A follow-up endoscopy after two months revealed that the fistula was closed and clinically improved. CLINICAL DISCUSSION: The quick clearance of contaminated sputum by coordinated peristalsis, paired with upright posture and an intact lower esophageal sphincter, limits the organism's exposure to the esophagus. CONCLUSION: Despite the disease's rarity, if not delayed, it can be efficiently managed with ATT to avoid major complications like esophageal perforation, which necessitates surgery.

Childhood cancer survivorship care during the COVID-19 pandemic: an international report of practice implications and provider concerns.

PURPOSE: Long-term follow-up (LTFU) care is essential to optimise health outcomes in childhood cancer survivors (CCS). We aimed to assess the impact of the COVID-19 pandemic on LTFU services and providers. METHODS: A COVID-19 working group within the International Late Effects of Childhood Cancer Guideline Harmonization Group (IGHG) distributed a questionnaire to LTFU service providers in 37 countries across Europe, Asia, North America, Central/South America, and Australia. The questionnaire assessed how care delivery methods changed during the pandemic and respondents' level of worry about the pandemic's impact on LTFU care delivery, their finances, their health, and that of their family and friends. RESULTS: Among 226 institutions, providers from 178 (79%) responded. Shortly after the initial outbreak, 42% of LTFU clinics closed. Restrictions during the pandemic resulted in fewer in-person consultations and an increased use of telemedicine, telephone, and email consultations. The use of a risk assessment to prioritise the method of LTFU consultation for individual CCS increased from 12 to 47%. While respondents anticipated in-person consultations to remain the primary method for LTFU service delivery, they expected significantly increased use of telemedicine and telephone consultations after the pandemic. On average, respondents reported highest levels of worry about psychosocial well-being of survivors. CONCLUSIONS: The pandemic necessitated changes in LTFU service delivery, including greater use of virtual LTFU care and risk-stratification to identify CCS that need in-person evaluations. IMPLICATIONS FOR CANCER SURVIVORS: Increased utilisation of virtual LTFU care and risk stratification is likely to persist post-pandemic.
