Meta-Analysis
Core needle biopsy (CNB) has been used with caution in pheochromocytoma and paraganglioma (PPGL) due to concerns about catecholamine-related complications. While it is unclear what scientific evidence supports this claim, it has limited the acquisition of biological samples for diagnostic purposes and research, especially in metastatic PPGL. We performed a systematic review and individual patient meta-analysis to evaluate the risk of complications after CNB in PPGL patients. The primary and secondary objectives were to investigate the risk of death and the occurrence of complications requiring intervention or hospitalization, respectively. Fifty-six articles describing 86 PPGL patients undergoing CNB were included. Of the patients (24/71), 34% had metastases and 53.4% (31/58) had catecholamine-related symptoms before CNB. Of the patients (14/41), 34.1% had catecholamine excess testing prior to the biopsy. No CNB-related deaths were reported. Four patients (14.8%, 4/27) experienced CNB-related complications requiring hospitalization or intervention. One case had a temporary duodenal obstruction caused by hematoma, two cases had myocardial infarction, and one case had Takotsubo cardiomyopathy. Eight patients (32%, 8/25) had CNB-related catecholamine symptoms, mainly transient hypertension, excessive diaphoresis, tachycardia, or hypertensive crisis. The scientific literature does not allow us to make any firm conclusion on the safety of CNB in PPGL. However, it is reasonable to argue that CNB could be conducted after thorough consideration, preparation, and with close follow-up for PPGL patients with a strong clinical indication for such investigation.

Review
BACKGROUND
Schistosomiasis is an endemic parasitic infection found in many tropical countries and is highly prevalent in sub-Saharan Africa. It can follow different and atypical clinical patterns. In these unusual cases, diagnosis may be difficult, as symptoms are unspecific. Arthropathy can appear in parasitic infections, but making a connection between arthritis and parasitic aetiology is difficult. This review aims to summarise all cases that have reported schistosomiasis associated with arthropathy, and the different ways authors have diagnosed this disease.
METHOD
We present a systematic literature review of schistosomiasis associated with joint impairments, with a focus on the difficulty of differentiating between reactive arthritis and its parasitic presence in situ.
RESULTS
Joint impairments mimicking polyarthropathy are not rare in parasitic infections. Diagnosis is difficult. On the one hand, some patients have arthritis with parasite eggs found in situ, particularly in synovial biopsy. These situations are less common and antiparasitic treatment is straightforward. On the other hand, arthritis can be associated with parasitic infections in the form of reactive arthritis due to an immunological reaction. In such cases, pathogenicity due to circulating immune complex should be suspected. Anti-inflammatory treatments such as corticosteroids or immunosuppressive therapies are ineffective in cases of schistosomal arthropathy. A joint fluid puncture appears to be necessary and parasitic examination as well as in situ immunological techniques appear to be important in order to confirm the diagnosis of schistosomal arthropathy.
CONCLUSIONS
The frequency of articular schistosomiasis is probably underestimated and should be sought when patients have unexplained polyarthropathy, as it can be an alternative diagnosis when patients have concomitant parasitic infections. These situations are common, whereas the association between unexplained inflammatory arthritis and a concomitant parasitic infection is rarely made. Unspecific rheumatism can lead to probabilistic treatments with many side effects, and looking for a parasitic aetiology could lead to repeated antiparasitic treatments and may avoid other immunosuppressive or corticosteroid therapies. With increasing travel and global migration, physicians need to be more aware of nonspecific symptoms that may reveal an atypical presentation of a tropical disease that can be treated easily, thus avoiding inappropriate immunosuppressive treatments.

PloS One 2018Breast tuberculosis in male is a rarely reported and poorly described condition. (Meta-Analysis)
Meta-Analysis Review
SETTING
Breast tuberculosis in male is a rarely reported and poorly described condition.
OBJECTIVE
To quantify the number of breast tuberculosis in men, to describe clinical presentation and to present the diagnostic and therapeutic procedures applied.
DESIGN
A systematic review of the literature including reports published in English, Spanish and French until December 2017.
RESULTS
The search yielded 26 cases of male breast tuberculosis, median age 56.5 years. Most presented with an isolated breast lump (89%), associated with axillary lymphadenitis (27.8%) and skin inflammation (33.3%). The most common constitutional symptoms were pain (64.7%) and fever (35.3%). Fine-needle aspiration cytology and culture were the most common diagnostic modality (61.5%). Standard anti-tuberculosis regimen was the main treatment, alone or accompanied or preceded by incision and drainage.
CONCLUSIONS
The risk of breast tuberculosis in men appears to be low, but the condition can be difficult to diagnose and the diagnostic delays can be long. Overall prognosis is good following standard anti-tuberculosis regimen with or without incision/drainage.

Review
Ultrasound (US) based classification systems exist for the stratification of thyroid nodules based on the risk for malignancy. This systematic review aimed to assess the evidence for the performance of US-based thyroid nodule classification systems through correlation with fine needle aspiration biopsy (FNAB). PubMed and Scopus were searched using keywords that included 'ultrasound classification', 'thyroid nodules', 'fine needle aspiration', and 'malignancy'. Inclusion criteria were as follows: studies/reviews reporting on US imaging for the classification of thyroid nodules. Exclusion criteria were as follows: no comparison between US imaging findings and histology reports based on FNAB, no full English text available/accessible. The database searches identified 66 publications. After evaluation, 12 studies met the inclusion criteria. Two US-based classification systems for thyroid nodules were assessed: the Thyroid Imaging Reporting and Data System (TIRADS) and the American Thyroid Association (ATA) guidelines. For TIRADS, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) ranged from 70.6% to 97.4%, 29.3% to 90.4%, 23.3% to 64.3%, and 87.1% to 99.0%, respectively. The median sensitivity, specificity, PPV, and NPV for TIRADS was 90.0%, 57.4%, 49.0%, and 91.0%, respectively. One study comparing TIRADS with the ATA guidelines demonstrated that TIRADS was superior in terms of sensitivity, whereas the ATA guidelines were superior in terms of specificity and PPV. The high sensitivity and NPV of the US-based TIRADS classification system have excellent utility for correctly classifying nodules as positive for malignant disease and for predicting the absence of malignant disease. The paucity of studies assessing the ATA guidelines highlights avenues for further research comparing TIRADS with other systems of thyroid nodule classification.

BACKGROUND
Primary liver tumours and liver metastases from colorectal carcinoma are two of the most common malignant tumours to affect the liver. The liver is second only to the lymph nodes as the most common site for metastatic disease. More than half of the people with metastatic liver disease will die from metastatic complications. Electrocoagulation by diathermy is a method used to destroy tumour tissue, using a high-frequency electric current generating high temperatures, applied locally with an electrode (needle, blade, or ball). The objective of this method is to destroy the tumour completely, if possible, in a single session. With the time, electrocoagulation by diathermy has been replaced by other techniques, but the evidence is unclear.
OBJECTIVES
To assess the beneficial and harmful effects of electrocoagulation by diathermy, administered alone or with another intervention, versus no intervention, other ablation methods, or systemic treatments in people with liver metastases.
SEARCH METHODS
We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, MEDLINE Ovid, Embase Ovid, LILACS, Science Citation Index Expanded, Conference Proceedings Citation Index - Science, CINAHL, ClinicalTrials.gov, ICTRP, and FDA to October 2020.
SELECTION CRITERIA
We considered all randomised trials that assessed beneficial and harmful effects of electrocoagulation by diathermy, administered alone or with another intervention, versus comparators, in people with liver metastases, regardless of the location of the primary tumour.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane. We assessed risk of bias of the included trial using predefined risk of bias domains, and presented the review results incorporating the certainty of the evidence using GRADE.
MAIN RESULTS
We included one randomised clinical trial with 306 participants (175 males; 131 females) who had undergone resection of the sigmoid colon, and who had five or more visible and palpable hepatic metastases. The diagnosis was confirmed by histological assessment (biopsy) and by carcinoembryonic antigen (CEA) level. The trial was conducted in Iraq. The age of participants ranged between 38 and 79 years. The participants were randomised to four different study groups. The liver metastases were biopsied and treated (only once) in three of the groups: 75 received electrocoagulation by diathermy alone, 76 received electrocoagulation plus allopurinol, 78 received electrocoagulation plus dimethyl sulphoxide. In the fourth intervention group, 77 participants functioning as controls received a vehicle solution of allopurinol 5 mL 4 x a day by mouth; the metastases were left untouched. The status of the liver and lungs was followed by ultrasound investigations, without the use of a contrast agent. Participants were followed for five years. The analyses are based on per-protocol data only analysing 223 participants. We judged the trial to be at high risk of bias. After excluding 'nonevaluable patients', the groups seemed comparable for baseline characteristics. Mortality due to disease spread at five-year follow-up was 98% in the electrocoagulation group (57/58 evaluable people); 87% in the electrocoagulation plus allopurinol group (46/53 evaluable people); 86% in the electrocoagulation plus dimethyl sulphoxide group (49/57 evaluable people); and 100% in the control group (55/55 evaluable people). We observed no difference in mortality between the electrocoagulation alone group versus the control group (risk ratio (RR) 0.98, 95% confidence interval (CI) 0.94 to 1.03; 113 participants; very low-certainty evidence). We observed lower mortality in the electrocoagulation combined with allopurinol or dimethyl sulphoxide group versus the control group (RR 0.87, 95% CI 0.80 to 0.95; 165 participants; low-certainty evidence). We are very uncertain regarding post-operative deaths between the electrocoagulation alone group versus the control group (RR 1.03, 95% CI 0.07 to 16.12; 152 participants; very low-certainty evidence) and between the electrocoagulation combined with allopurinol or dimethyl sulphoxide groups versus the control group (RR 1.00, 95% CI 0.09 to 10.86; 231 participants; very low-certainty evidence). The trial authors did not report data on number of participants with other adverse events and complications, recurrence of liver metastases, time to progression of liver metastases, tumour response measures, and health-related quality of life. Data on failure to clear liver metastases were not provided for the control group. There was no information on funding or conflict of interest. We identified no ongoing trials.
AUTHORS' CONCLUSIONS
The evidence on the beneficial and harmful effects of electrocoagulation alone or in combination with allopurinol or dimethyl sulphoxide in people with liver metastases is insufficient, as it is based on one randomised clinical trial at low to very low certainty. It is very uncertain if there is a difference in all-cause mortality and post-operative mortality between electrocoagulation alone versus control. It is also uncertain if electrocoagulation in combination with allopurinol or dimethyl sulphoxide may result in a slight reduction of all-cause mortality in comparison with a vehicle solution of allopurinol (control). It is very uncertain if there is a difference in post-operative mortality between the electrocoagulation combined with allopurinol or dimethyl sulphoxide group versus control. Data on other adverse events and complications, failure to clear liver metastases or recurrence of liver metastases, time to progression of liver metastases, tumour response measures, and health-related quality of life were most lacking or insufficiently reported for analysis. Electrocoagulation by diathermy is no longer used in the described way, and this may explain the lack of further trials.

Review
BACKGROUND
Currently, there is a lack of clear guidelines regarding evaluation and management of giant juvenile fibroadenomas. The purpose of this study was to conduct a systematic review of giant juvenile fibroadenomas and to evaluate the most common diagnostic and therapeutic modalities.
METHODS
A systematic literature search of PubMed and MEDLINE databases was conducted in February 2014 to identify articles related to giant juvenile fibroadenomas. Pooled outcomes are reported.
RESULTS
Fifty-two articles (153 patients) met inclusion criteria. Mean age was 16.7 years old, with a mean lesion size of 11.2 cm. Most patients (86%) presented with a single breast mass. Imaging modalities included ultrasound in 72.5% and mammography in 26.1% of cases. Tissue diagnosis was obtained using a core needle biopsy in 18.3% of cases, fine-needle aspiration (FNA) in 25.5%, and excisional biopsy in 11.1% of patients. Surgical treatment was implemented in 98.7% of patients (mean time to treatment of 9.5 months, range, 3 days to 7 years). Surgical intervention included excision in all cases, of which four were mastectomies. Breast reconstruction was completed in 17.6% of cases. There were no postoperative complications.
CONCLUSIONS
Diagnosis and treatment of giant juvenile fibroadenoma is heterogeneous. There is a paucity of data to support observation and non-operative treatment. The most common diagnostic modalities include core needle or excisional biopsy. The mainstay of treatment is complete excision with an emphasis on preserving the developing breast parenchyma and nipple areolar complex. Breast reconstruction is uncommon, but may be necessary in certain cases.

Review
INTRODUCTION
Transrectal ultrasound-guided biopsies (TRUS-gb) are associated with both mild and serious complications. Prophylactic antibiotics reduce the risk of septicaemia and mortality; however, no international consensus exists on the timing and duration of antibiotics, including the optimal drug strategy. We reviewed the current evidence supporting use of prophylactic antibiotics and the risk of complications following prostate biopsies.
METHODS
This review was drafted in accordance with the Prisma Guidelines. The PubMed, Embase and Cochrane databases were searched.
RESULTS
A total of 19 eligible trials were identified. One trial demonstrated a significant reduction in the risk of infection after biopsy and reported that oral ciprofloxacin as either a single-dose or a three-day regimen was superior to oral chloramphenicol and norfloxacin. Of three studies investigating the timing of the first dose of antibiotic, one study found that administration 24 h before biopsy versus administration immediately before reduced the relative risk of post-biopsy infection by 55%. Seven studies compared different durations of antibiotic prophylaxis. None showed any benefit from continuing prophylaxis beyond a single dose or a one-day regimen.
CONCLUSION
Evidence supporting a specific antibiotic regimen for TRUS-gb prophylaxis is scarce. Widespread use of fluoroquinolone prophylaxis may be associated with an increase in resistant Escherichia coli strains, posing a potentially major health issue in the future. .

Meta-Analysis
BACKGROUND AND OBJECTIVES
Kidney biopsy is an essential tool for the diagnosis and treatment of patients with kidney disease; however, because of its invasive nature, bleeding complications may arise.
DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS
We performed a meta-analysis of prospective or retrospective observational studies and randomized, controlled trials in pediatric patients undergoing native or transplant kidney biopsy in an inpatient or outpatient setting in MEDLINE-indexed studies from January 1998 to November 1, 2017 to determine the proportion of patients who develop hematoma, need blood transfusion, or need an additional intervention due to a complication after kidney biopsy.
RESULTS
Twenty-three studies of 5504 biopsies met inclusion criteria. The proportion of patients developing hematoma after biopsy was between 11% (95% confidence interval, 7% to 17%) and 18% (95% confidence interval, 9% to 35%) using two analyses that included different time periods. The proportion needing blood transfusion was 0.9% (95% confidence interval, 0.5% to 1.4%). The proportion needing an additional intervention due to postbiopsy complication was 0.7% (95% confidence interval, 0.4% to 1.1%). Secondary analysis was not possible due to lack of data in the original manuscripts on laboratory values, needle gauges, number of needle passes, age of patient, or performer (attending versus trainee). Analysis with metaregression found that use of real-time ultrasound during biopsy did not modify the risk for hematoma, requirement of a blood products transfusion, or requirement of an additional procedure after biopsy. Analysis with metaregression comparing native biopsies with transplant biopsies did not reveal that biopsy type (native kidney biopsy versus transplant kidney biopsy) was associated with the need for a blood transfusion or requirement of an additional intervention after biopsy.
CONCLUSIONS
The development of perinephric hematoma after kidney biopsy is not an infrequent finding. The proportion of patients requiring blood transfusion or needing an additional intervention as a result of kidney biopsy in pediatric patients is significantly smaller.

Orphanet Journal of Rare Diseases Apr 2021Hepatic Actinomycosis (HA) is one of the infections that causes disorders in patients when diagnosed untimely and inappropriately. (Review)
Review
BACKGROUND
Hepatic Actinomycosis (HA) is one of the infections that causes disorders in patients when diagnosed untimely and inappropriately.
METHODS
Case reports on HA in patients published between 2000 and April 2020 were gathered by carrying out a structured search through PubMed/Medline.
RESULTS
Through 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.
CONCLUSION
HA 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.

Meta-Analysis Review
It is important to define the accuracy of fine-needle aspiration cytology (FNAC) in the diagnosis of Warthin tumor (WT). This systematic review and meta-analysis evaluated the accuracy of FNAC in the diagnosis of WT in the parotid gland and WT growth rate. For determination of FNAC accuracy, 17 studies, encompassing 1710 cases, were included. Pulled random model estimates of sensitivity, specificity, PPV, and NPV were 93.7% (95%CI: 92.1, 95.3), 97.9% (95%CI: 97, 98.9), 93.3% (95%CI: 91.5, 95.1), and 97.4% (95%CI: 96.4, 98.4), respectively. FNAC is highly reliable for the diagnosis of WT of the parotid. The high PPV value suggests that patients with a cytological diagnosis of WT of the parotid may be assigned to active surveillance.
