Project description:AimsMyocardial calcification is an unusual condition in which excess calcium is deposited in the myocardium. Herein, we report two cases of myocardial calcification from our clinical experience. Furthermore, we conduct a systematic review to examine the clinical course and associated pathologies of myocardial calcification.Methods and resultsThis systematic review was registered in PROSPERO (CRD42023463285). PubMed and Scopus were searched according to the following inclusion criteria: (i) case reports or case series describing patients with myocardial calcification; (ii) diagnosis of myocardial calcification by computed tomography (CT); (iii) adequate description of patients, including their chief complaint, medical history, evaluations, and treatments; and (iv) publication in English. Among the 75 patients, 24 had sepsis, 14 had myocarditis, and 37 had other pathologies. The mortality rate was 33% for patients with sepsis, 14% for patients with myocarditis, and 11% for patients with other pathologies. Follow-up CT findings beyond 2 years were reported in six patients, showing that the CT findings of myocardial calcification persisted but subsided over time. Autopsy was performed in seven patients, and extensive interstitial fibrosis and collection of inflammatory cells were observed in patients with myocarditis, sepsis, and ischaemic heart disease.ConclusionWhile various medical conditions can cause myocardial calcification, accompanying conditions commonly reported with myocardial calcification were sepsis and myocarditis. The CT findings of myocardial calcification tend to regress over time if the underlying disease can be treated.

Project description:Pervasive refusal syndrome (PRS) is a complex condition that affects young people leading to social withdrawal, inability or refusal to eat, drink, mobilise or speak. The affected individual regresses and is unable to self-care and quite characteristically will resist rehabilitation, worsen with praise or remain entirely passive. This systematic review was aimed at describing clinical features of PRS, current interventions and to summarise some of the nosological aspects of the condition. Without language restriction, an electronic search was conducted in Embase, PsychInfo, Medline, Cochrane library, and PubMed databases yielding 29 articles with a total of 79 cases. We performed a risk of assessment bias using an adapted Newcastle-Ottawa Scale and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. 124 articles were identified, of which 29 were included and these yielded 79 cases. Seventy-six percent of the studies had a low rate of risk of assessment bias (good quality). Our results show that PRS overlaps with several conditions, mainly affects young females aged 7-15 years and has a recovery rate of 78% if diagnosed and treated early but the duration of inpatient treatment may last up to 9.44 months (8.82 SD). The patients had multiple inter-dependent risks. The major predisposing factors included vulnerable premorbid personality and pre-existing mental disorder. Precipitating factors were stressors such as infection and traumatic experiences. Enmeshed parent-child relationship served as a maintaining factor. The themes of treatment approach are essentially rehabilitative: (1) working collaboratively with patient and family, (2) having access to multidisciplinary team, and (3) peer/group supervision. This study has systematically evaluated a large sample of patients with PRS to ascertain its clinical features and the core elements of its treatment. Its key treatment approach is a multi-modal rehabilitative strategy that is compassionate, transparent and inclusive.

Project description:ObjectiveTo evaluate and compare the hearing outcome after the bony obliteration tympanoplasty (BOT), canal wall up (CWU) without mastoid obliteration and canal wall down (CWD) without mastoid obliteration in a large patient cohort. As the aeration of the middle ear is associated with hearing outcome, we hypothesized that the post-operative hearing after the BOT may be better compared to CWU and CWD without obliteration.MethodsThis is a retrospective cohort study on all adult patients who underwent the BOT, CWU without obliteration or CWD without obliteration for primary or revision cholesteatoma between January 2003 and March 2019 with audiological follow-up at our institution. Pre-operative, short-term post-operative and long-term post-operative hearing tests were analyzed and potential factors influencing post-operative hearing were assessed.Results626 ears were included. We found no significant differences between the short-term and long-term post-operative audiometry. The pre-operative air-bone gap (ABG) was the factor with the largest effect size on change in air-bone gap (ABG) between pre- and post-operative. When stratifying for this factor along with the type of ossicular chain reconstruction to account for differences at baseline, no significant differences in post-operative ABG were found between BOT and non-obliteration CWU and CWD.ConclusionIn this large retrospective cohort study, we found no significant differences in post-operative ABG between the BOT and the non-obliteration CWU and CWD. A solid comparison of hearing between groups remains very challenging as hearing outcome seems to be dependent on many different factors. Hearing outcome seems to be no additional argument to choose for BOT over non-obliteration surgery.

Project description:Background and Objectives: Bartter syndrome (BS) is a rare group of autosomal-recessive disorders that usually presents with hypokalemic metabolic alkalosis, occasionally with hyponatremia and hypochloremia. The clinical presentation of BS is heterogeneous, with a wide variety of genetic variants. The aim of this systematic review was to examine the available literature and provide an overview of the case reports and case series on BS. Materials and Methods: Case reports/series published from April 2012 to April 2022 were searched through Pubmed, JSTOR, Cochrane, ScienceDirect, and DOAJ. Subsequently, the information was extracted in order to characterize the clinical presentation, laboratory results, treatment options, and follow-up of the patients with BS. Results: Overall, 118 patients, 48 case reports, and 9 case series (n = 70) were identified. Out of these, the majority of patients were male (n = 68). A total of 21 patients were born from consanguineous marriages. Most cases were reported from Asia (73.72%) and Europe (15.25%). In total, 100 BS patients displayed the genetic variants, with most of these being reported as Type III (n = 59), followed by Type II (n = 19), Type I (n = 14), Type IV (n = 7), and only 1 as Type V. The most common symptoms included polyuria, polydipsia, vomiting, and dehydration. Some of the commonly used treatments were indomethacin, potassium chloride supplements, and spironolactone. The length of the follow-up time varied from 1 month to 14 years. Conclusions: Our systematic review was able to summarize the clinical characteristics, presentation, and treatment plans of BS patients. The findings from this review can be effectively applied in the diagnosis and patient management of individuals with BS, rendering it a valuable resource for nephrologists in their routine clinical practice.

Project description:PurposeTo evaluate the surgical results of revision canal wall down (CWD) surgery for chronically discharging mastoid cavities and to compare the non-obliteration approach to mastoid obliteration with canal wall reconstruction.MethodsThis is a retrospective cohort study. All adult patients (≥ 18 years) who underwent revision surgery for chronically draining mastoid cavities between January 2013 and January 2020 were included. Primary outcome measures included the dry ear rate, complications and postoperative hearing.Results79 ears were included; 56 ears received revision CWD with mastoid obliteration and posterior canal wall reconstruction and 23 ears received CWD without mastoid obliteration. The dry ear rate at the most recent outpatient clinic visit (median 28.0 months postoperative) was significantly higher in the obliteration group with 96.4% compared to 73.9% for the non-obliteration group (p = .002). There were no differences in audiological outcome and incidence of complications between the two techniques.ConclusionWe show that in our study population revision CWD surgery with mastoid obliteration and posterior canal wall reconstruction is superior to revision CWD surgery without mastoid obliteration in the management of chronically discharging mastoid cavities. In the obliteration group, a dry ear was achieved in 96.4% as this was 73.9% in the non-obliteration group. We found no differences in audiological outcome and in incidence of complications between the two techniques.

Project description:BackgroundHepatic Actinomycosis (HA) is one of the infections that causes disorders in patients when diagnosed untimely and inappropriately.MethodsCase reports on HA in patients published between 2000 and April 2020 were gathered by carrying out a structured search through PubMed/Medline.ResultsThrough a survey of the Medline database, 130 studies were identified and then, 64 cases with HA were included in the final analysis. Asia had the largest share of cases with 37.5% (24 reports), followed by Europe and the Americas. Affected patients were predominantly males (64%) and the overall mortality rate was 1% with only one male patient in his 50 s dying. Nearly all patients (92%) were immunocompetent. However, in four patients, the use of immunosuppressive medication led to depression of the immune system. Most of the patients (80%) experienced complications. In terms of the complications, the most frequent ones were previous history of abdominal surgery (32%) and foreign bodies in the abdominopelvic region (20%). Actinomyces israelii was the most common pathogen isolated from patients. Abdominal pain (66%), fever (62%), weight loss (48%), night sweat, malaise, and anorexia (14%) over about 3.1 months were the most frequently reported clinical symptoms. Extension to one or more surrounding organs was evident in 18 patients (28%). Histopathologic examination confirmed infection in 67% of the patients and samples obtained from liver puncture biopsy (32%) were most frequently used in diagnosis. Surgery or puncture drainage + anti-infection was the most common method to treat patients and penicillin, Amoxicillin, Doxycycline, and ampicillin were the most frequently used drugs to control infection.ConclusionHA should be considered in patients with a subacute or chronic inflammatory process of the liver. With accurate and timely diagnosis of infection, extensive surgery can be prevented.

Project description:Ovarian pregnancy is a rare but well-known pathology. However, pathophysiology, diagnosis and treatment are not established. Therefore, all case reports on ovarian pregnancy published in PubMed from November 2011 till November 2022 were reviewed and two case reports were added. In these 84 case reports, 8% of ovarian pregnancies occurred in women without or with blocked oviducts and 23% were localised on the other side than the corpus luteum. Since symptoms are not specific, ovarian pregnancy has to be suspected in all women with abdominal bleeding. Surgical excision is the preferred treatment. However, since an associated intra-uterine pregnancy cannot be excluded, care should be taken not to interrupt this intra-uterine pregnancy with the uterine cannula or by damaging the corpus luteum. In conclusion, in women with abdominal bleeding, an ovarian pregnancy cannot be excluded, even in women with a negative pregnancy test or an empty uterus on transvaginal ultrasonography. Therefore, a laparoscopy is indicated but the surgeon should realise that an associated intra-uterine pregnancy also cannot be excluded and that therefore care should be taken not to interrupt this intra-uterine pregnancy by the uterine cannula or by damaging the corpus luteum.

Project description:BackgroundThe gut fermentation syndrome (GFS), also known as the endogenous alcohol fermentation syndrome or auto brewery syndrome, is a rare and underdiagnosed medical condition where consumed carbohydrates are converted to alcohol by the microbiota in the gastrointestinal or urinary tract. The symptoms of GFS can have severe impact on patients' wellbeing and can have social and legal consequences. Unfortunately, not much is reported about GFS. The aim of this systematic review was to assess the evidence for GFS, causal micro-organisms, diagnostics, and possible treatments.MethodsA protocol was developed prior to initiation of the systematic review (PROSPERO 207182). We performed a literature search for clinical studies on 1 September 2020 using PubMed and Embase. We included all clinical studies, including case reports that described the GFS.ResultsIn total, 17 case reports were included, consisting of 20 patients diagnosed with GFS. The species that caused the GFS included Klebsiella pneumoniae, Candida albicans, C. glabrata, Saccharomyces cerevisiae, C. intermedia, C. parapsilosis, and C. kefyr.ConclusionsGFS is a rare but underdiagnosed disease in daily practice. The disease is mostly reported by Saccharomyces and Candida genera, and some cases were previously treated with antibiotics. Studies in Nonalcoholic Fatty Liver disease suggest a bacterial origin of endogenous alcohol-production, which might also be causal micro-organisms in GFS. Current treatments for GFS include antibiotics, antifungal medication, low carbohydrate diet, and probiotics. There might be a potential role of fecal microbiota transplant in the treatment of GFS.

Project description:ObjectiveTo prevent cavity problems in canal wall down mastoidectomy, silicone block for mastoid obliteration was used.MethodsIn this retrospective cohort study, 39 patients (21 males and 18 females) underwent canal wall down mastoidectomy and mastoid obliteration using silicone block. We evaluated the postoperative outcome, the time until epithelialization of the cavity, graft success rate, and the hearing outcome.ResultsThe time until complete epithelialization of the mastoid cavity was 35.5 ± 5.4 days. We had a graft success rate of 100% during the follow-ups. The postoperative evaluation revealed 36 dry ears (92.3%) patients without any cavity problems. However, one ear developed granulation tissue, and two ears had partially exposed silicone block, which required revision mastoidectomy. Regarding hearing outcomes, a complication such as deaf ear was not reported.ConclusionSilicone block is safe and suitable for mastoid obliteration and external auditory canal reconstruction in canal wall down mastoidectomy.Level of evidence4.

Project description:BackgroundMucormycosis is a lethal fungal infection with increasing incidence. The epidemiology of mucormycosis in current mainland China has not been fully elucidated.ObjectivesTo investigate the epidemiology, risk factors, manifestations, diagnosis, treatment and prognosis of mucormycosis in mainland China.MethodsWe searched for published mucormycosis case reports/series in mainland China in the PubMed, WanFang and China National Knowledge Infrastructure databases from January 2001 to July 2020. Cases of proven/probable mucormycosis were included.ResultsA total of 390 cases were included in this review. Most of the patients were male (61.3%), and diabetes was the most common predisposing factor (37.2%). Pulmonary mucormycosis (42.1%) was the most common form followed by cutaneous infection (21.0%). Of 390 patients, 24 died before therapy. Among the remaining 366 patients, 208 (56.8%) received antifungal drugs alone, 16 (4.4%) received surgery alone, and 142 (38.8%) received a combination of drugs and surgery, the mortality of the last group is much lower (34/142, 23.9%). The overall mortality was 37.2%. A multivariate analysis indicated that factors associated with increased mortality included corticosteroid use alone as immunosuppressive therapy, rhino-orbito-cerebral or disseminated mucormycosis (compared with pulmonary mucormycosis), and drug administration other than amphotericin B (AmB), posaconazole (POS) and itraconazole (ITR) (compared with the use of conventional AmB), while factors associated with decreased mortality included cutaneous mucormycosis and surgical therapy. Combination or sequential antifungal therapy of AmB and POS or ITR did not reduce mortality compared with conventional AmB monotherapy.ConclusionIn mainland China, mucormycosis is a serious fungal infection with high mortality. Corticosteroid use, rhino-orbito-cerebral and disseminated mucormycosis were adverse prognostic factors. Antifungal therapy combined with surgery could improve the prognosis.
