A novel case of lupus nephritis and mixed connective tissue disorder in a COVID-19 patient

Introduction

Mixed connective tissue disease (MCTD) is a rare autoimmune condition characterized by Scleroderma, Polymyositis, and Systemic Lupus Erythematous (SLE). Though a possible relationship between COVID-19 and autoimmune diseases has been recently reported, its pathophysiological mechanism behind flares in Lupus Nephritis (LN), a complication of SLE, remains unknown.

Case presentation

A 22-year-old COVID-19 positive female presented with anemia, bilateral pitting edema, periorbital swelling, and posterior cervical lymphadenitis. Further inspection revealed lower abdominal striae, hepatosplenomegaly, and hyperpigmented skin nodules. Complete blood counts showed elevated inflammatory markers and excessively high protein creatinine ratio. Antinuclear antibody titers were elevated (anti-smith and U1 small nuclear ribonucleoprotein) and Rheumatoid Factor was positive. She was diagnosed with MCTD associated with a flare of LN. To control her lupus flare, a lower dose of steroids was initially administered, in addition to oral hydroxychloroquine and intravenous cyclophosphamide. Her condition steadily improved and was discharged on oral steroid maintenance medication.

Discussion

We present a rare phenomenon of newly diagnosed LN, a complication of SLE, with MCTD in a PCR-confirmed COVID-19 patient. The diagnostic conundrum and treatment hurdles should be carefully addressed when patients present with lupus and COVID-19 pneumonia, with further exploration of the immuno-pathophysiology of COVID-19 infection in multi-systemic organ dysfunction in autoimmune disorders.

Conclusion

In COVID-19 patients with LN and acute renal injury, it is critical to promptly and cautiously treat symptomatic flares associated with autoimmune disorders such as SLE and MCTD that may have gone unnoticed to prevent morbidity from an additional respiratory infection.

•

SLE disease has been associated with COVID-19. However, there is a lack of data on LN in conjunction with MCTD in COVID-19 positive patients.

•

A possible relationship between Coronavirus disease 2019 (COVID-19) and autoimmune disease has been documented in many case reports.

•

Because of the overlapping clinical manifestations and laboratory findings between lupus and COVID-19 pneumonia, the diagnostic problems and treatment hurdles should be carefully addressed.

•

In COVID-19 patients with LN flare and acute renal injury, it is critical to resolve any reversible causes of the kidney injury and manage the COVID-19 before treating the LN.

Candida glabrata infection of a pancreatic pseudocyst in a COVID-19 patient: A case report and review of the literature

Introduction

Pancreatic pseudocysts remain a feared complication of acute or chronic pancreatitis and are often characterized by collections of fluids due to underlying damage to the pancreatic ducts, culminating in a walled-off region bereft of an epithelial layer but surrounded by granulation tissue. While fungal infections of pancreatic pseudocysts are rarely encountered, candida albicans remains the most frequently implicated organism.

Case presentation

A 55-year-old male presented with pain in the left-hypochondriac region, accompanied by non-bilious emesis and nausea. Interestingly, the patient also tested positive for a COVID-19 infection. Investigative workup divulged enhancing pancreatic walls with a radiologic impression consistent with a pancreatic pseudocyst. An ultrasound-guided external drainage was performed; the drainage was conducted unremarkably, with the resultant fluid collection revealing the presence of Candida Glabrata. The patient was commenced on antifungal therapy and continues to do well to date.

Discussion

Infectious ailments of pancreatic pseudocysts remain a widely known complication of acute pancreatitis. While it is rare, fungal infection is a crucial consideration for patients with pancreatic pseudocysts, especially in the context of a lack of an adequate response to antibiotics, deterioration, comorbidities, and immunocompromised states.

Conclusion

Rapid identification of the microbe responsible for pancreatic pseudocyst infection is vital for time-sensitive treatment and a more rapid recovery, curbing associated morbidity and mortality.

•

Fungal infections of pancreatic pseudocysts remain a rare but well-characterized complication, culminating in significant morbidity and mortality.

•

Telltale signs include unresponsiveness to antibiotics and worsening clinical symptoms.

•

Rapid identification of the responsible microbe is vital for time-sensitive treatment and a more rapid recovery.

Meckel's diverticulum causing acute intestinal obstruction: A case report and comprehensive review of the literature

Introduction

Meckel's diverticulum is a congenital anomaly that is often detected incidentally. When it presents symptomatically, it causes painless gastrointestinal bleeding. Nevertheless, in rare instances, it can cause acute intestinal obstruction, often obscuring the true clinical picture.

Case presentation

A 31-year-old male presented to the emergency department with a 24-h history of unremitting nausea, biliary emesis, abdominal distension, and absolute constipation. After ruling out the most common etiologies of acute bowel obstruction, radiological imaging was obtained and was suggestive of meckel's diverticulum. Laparoscopic meckel's diverticulectomy was performed, with the subsequent histopathological analysis confirming ectopic gastric tissue.

Discussion

Meckel's diverticulum occurs consequent to incomplete obliteration of the vitelline or omphalomesenteric duct, which connects the developing intestines to the yolk sac. It is found in roughly 2% of the population, of which only about 4% may become symptomatic due to any number of complications. Specifically, small bowel obstruction (SBO) and diverticulitis secondary to ectopic gastric or pancreatic tissue are the most common presentations of symptomatic MD.

Conclusion

Although relatively rare in adults, MD should be considered in the list of differentials in patients with intussusception leading to SBO, especially on a background history unremarkable for the most common etiologies causing SBO including post-operative adhesions and hernias.

Pain management during diagnostic office hysteroscopy in postmenopausal women: a randomized study

Objective: This study aimed to compare efficacy and safety of lidocaine versus tramadol versus placebo in reducing the pain of diagnostic outpatient hysteroscopy (OH) in postmenopausal women.Materials and methods: This randomized double-blinded study included 156 menopausal women who received intrauterine lidocaine infusion or oral tramadol (50 mg) or placebo before diagnostic OH (52 women/group). Primary outcome was pain severity during the procedure using a 10-cm visual analog scale. Secondary outcomes were pain scores 10 and 30 min post procedure, satisfaction level, and ease of cervical entry.Results: Lidocaine had lower pain scores compared to placebo during and 10 min after the procedure (p < 0.001). Tramadol had lower pain scores than placebo during the procedure (p = 0.04), 10 min after the procedure (p = 0.03), and 30 min after the procedure (p = 0.04). Both lidocaine and tramadol resulted in an easier procedure than placebo (p < 0.001 and p = 0.04, respectively). Lidocaine had an easier cervical entry compared to tramadol (p = 0.004). Satisfaction scores in the lidocaine and tramadol groups were significantly higher than in the placebo group (p < 0.001).Conclusions: Lidocaine and tramadol were effective in reducing postmenopausal women-reported pain during and after diagnostic OH. However, lidocaine was better than tramadol in facilitating hysteroscope passage through the cervical canal and the reduction in pain levels with lidocaine was clinically relevant.Trial registration number: NCT03701984.

Fecal carriage of extended-spectrum β-lactamase- and carbapenemase-producing Enterobacteriaceae in Egyptian patients with community-onset gastrointestinal complaints: a hospital -based cross-sectional study

Objectives

The aim of this study was to determine the prevalence of extended-spectrum β-lactamase (ESBL) and carbapenemase production among Enterobacteriaceae isolated from ambulatory patients with gastrointestinal complaints admitted to El-Ahrar General Hospital, Zagazig, Egypt in the period between January 2013 and May 2013.

Methods

One hundred and thirteen Enterobacteriaceae isolates were recovered from 100 consecutive Egyptian patients with community–onset gastrointestinal complaints. The fecal samples were plated directly on selective EbSA-ESBL Screening Agar and on MacConkey agar. Isolate identification was performed with matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Screening for ESBLs and carbapenemases production was done by both the automated VITEK®2 system with AST N198 and by disk diffusion method. Real-time PCR and sequencing were used to characterize the resistance genes. Phylogroups of the E. coli isolates were determined by a triplex PCR-based method.

Results

Of 100 patients screened for fecal colonization with extended-spectrum β-lactamase -producing Enterobacteriaceae (ESBL-E) and carbapenemase- producing Enterobacteriaceae (CPE), 68 were colonized with ESBL-E whereas five patients were positive for CPE. One hundred and thirteen Enterobacterceae isolates were recovered from 100 fecal samples, they belonged to E. coli (n = 72), Klebsiella pneumoniae (n = 23), Enterobacter cloacae(n = 3), Salmonella spp. (n = 1) and other Enterobacterceae isolates (n = 14). The bla_CTX-M gene was detected in 89.04% (65/73) of the ESBL-producing Enterobacteriaceae, whereas bla_SHV and bla_TEM were detected in 30.14% (22/73) and 19.18% (14/73) respectively. Three out of 5 carbapenem-resistant isolates harbored New Delhi metallo-beta-lactamase (NDM) and 2 produced Verona integron-encoded metallo- beta -lactamase (VIM). Twenty-two (47.83%) of the ESBL positive isolates were multidrug resistant (MDR). Phylogenetic analysis showed that, of the 51 ESBL-EC isolates, 17 belonged to group B2, 13 to group D, 11 to group A and 10 to group B1.

Conclusions

Nearly two-thirds of the Enterobacteriaceae isolates recovered from feces of ambulatory patients with community–onset gastrointestinal complaints admitted to El-Ahrar General Hospital, Zagazig, Egypt were ESBL producers and one in every 20 patients included in our study was colonized by carbapenemase-producing Enterobacteriaceae. These high colonization rates are worrying, therefore prudent antimicrobial use should be adopted in Egyptian community settings.

Diagnosis and surgical repair of entero-cystocele in a cat

A five-month-old male Shiraze cat was referred to the Mansoura Veterinary Teaching Hospital of Mansoura University, Mansoura, Egypt for evaluation of a 5-days history of swelling in the caudal ventral abdomen after trauma, persistent straining and inability to urinate. Clinical examination, abdominal ultrasonography and exploratory laparotomy revealed herniation and herniorraphy was attempted. The herniated organs were urinary bladder and intestine through an abdominal wall defect. Clinical signs resolved after surgical reduction of the intestine and urinary bladder. Follow-up by telephone three months postoperatively confirmed that the cat had no problems with defecation or micturition. Entero-cystocele in a young cat after trauma has not been reported previously to the author’s knowledge.

Introduction and enzootic of A/H5N1 in Egypt: Virus evolution, pathogenicity and vaccine efficacy ten years on

It is almost a decade since the highly pathogenic H5N1 avian influenza virus (A/H5N1) of clade 2.2.1 was introduced to Egypt in 2005, most likely, via wild birds; marking the longest endemic status of influenza viruses in poultry outside Asia. The endemic A/H5N1 in Egypt still compromises the poultry industry, poses serious hazards to public health and threatens to become potentially pandemic. The control strategies adopted for A/H5N1 in Egyptian poultry using diverse vaccines in commercialized poultry neither eliminated the virus nor did they decrease its evolutionary rate. Several virus clades have evolved, a few of them disappeared and others prevailed. Disparate evolutionary traits in both birds and humans were manifested by accumulation of clade-specific mutations across viral genomes driven by a variety of selection pressures. Viruses in vaccinated poultry populations displayed higher mutation rates at the immunogenic epitopes, promoting viral escape and reducing vaccine efficiency. On the other hand, viruses isolated from humans displayed changes in the receptor binding domain, which increased the viral affinity to bind to human-type glycan receptors. Moreover, viral pathogenicity exhibited several patterns in different hosts. This review aims to provide an overview of the viral evolution, pathogenicity and vaccine efficacy of A/H5N1 in Egypt during the last ten years.

Emergence of a novel cluster of influenza A(H5N1) virus clade 2.2.1.2 with putative human health impact in Egypt, 2014/15

A distinct cluster of highly pathogenic avian influenzaviruses of subtype A(H5N1) has been found to emergewithin clade 2.2.1.2 in poultry in Egypt since summer2014 and appears to have quickly become predominant.Viruses of this cluster may be associated withincreased incidence of human influenza A(H5N1) infectionsin Egypt over the last months.

Effect of topical anti-inflammatory drugs on corneal and limbal wound healing

PURPOSE

To examine the effect of topical treatment with either steroidal or nonsteroidal anti-inflammatory drugs (NSAIDs) on the wound healing of corneal and limbal incisions using histologic criteria.

SETTING

Loyola University Medical Center, Maywood, Illinois, USA.

METHODS

Eighteen eyes of 9 cats were used for the study. All right eyes received a temporal limbal incision and the left eyes, a clear corneal incision. All eyes were treated with ofloxacin 0.3% postoperatively for 3 days. The animals were equally divided among 3 groups. Group 1 received topical steroid drops (prednisolone acetate 1%) for 7 days maximum; Group 2 received topical NSAID drops (ketorolac tromethamine 0.5%) for 7 days maximum; Group 3 received no additional treatment. One animal from each group was killed and the eye enucleated 3, 7, or 28 days postoperatively. The eyes were processed for staining with hematoxylin-eosin and smooth muscle actin, and corneal sections were evaluated in a blind fashion by an ophthalmic pathologist.

RESULTS

Three and 7 days after surgery (1) the limbal incision exhibited more prominent wound healing than the similarly treated clear corneal incision, and (2) the steroid-treated corneas had less wound healing than untreated or NSAID-treated corneas. At 28 days, the wounds in all eyes were almost completely healed.

CONCLUSIONS

Limbal incisions heal faster than clear corneal incisions. Steroids, but not NSAIDs, inhibit wound healing. Cataract surgery using limbal incisions and postoperative topical NSAIDs may result in faster wound healing and provide a reduced risk of related postoperative complications.

An educational approach to leprosy control: an evaluation of knowledge, attitudes and practice in two poor localities in Bombay, India

Based on the hypothesis that a systematic, carefully planned educational approach to leprosy would yield results in terms of knowledge, attitudes and case presentation superior to those of the established and traditional mass survey method, ALERT-India launched a programme in S ward of Bombay in February 1985, to compare the two. An intensive programme of health education, using trained teams, was carried out in one zone of this ward over a period of 12 months. Eight months later, mass survey work (as used routinely in previous years and on a country-wide basis) was carried out in an adjacent zone. In 1987, the Centre for Social and Technological Change in Bombay, in association with the School of Oriental and African Studies, University of London, was requested to evaluate the effect of the above educational approach in terms of knowledge, attitudes and practice in both the trial and control zones. Other aspects of this experimental approach, including its cost and effectiveness in identifying cases of leprosy, will be published separately. The design of the 'KAP' evaluation and the social and environmental controls introduced in the statistical analysis are described. The results pointed to a considerable degree of ignorance about leprosy as a disease (and its treatment) in both the study and the control zones. Knowledge about early symptoms was particularly weak and on all aspects scores for women were invariably lower than men. General education enhanced the absorption of specific knowledge, and the education of children compensated adequately for lack of parental education in this respect. Overall the evaluation indicated that the intensive educational approach was superior to the survey approach in terms of improving knowledge, attitudes and practice.
