Cross-sectional imaging often reveals unexpected pancreatic cystic lesions, it is a frequent clinical problem, Should we observe or remove it? What's the diagnosis? Is our patient in danger of malignancy?
Don’t miss this @aegastro @my_ueg #EducAEG #UEGambassador twitter thread

Importance of Pancreatic Cystic Neoplasms (PCN):
Most are asymptomatic at diagnosis, frequency increases with age
Symptoms: acute pancreatitis (Wirsung obstructed by the cyst or mucus), pain, obstructive chronic pancreatitis, jaundice
> symptoms, >malignancy risk!
Classification of PCN:
Mucinous: intraductal papillary mucinous neop. and mucinous cystic neop.
Nonmucinous: serous cystic neoplasm, solid pseudopapillary neoplasm and cystic neuroendocrine tumours
Endoderm- derived columnar epithelium is characteristic for mucinous lesions
👇
Intraductal papillary mucinous neoplasms (IPMN)
Characterized by papillary proliferation+mucus production. It may involve Wirsung (becomes dilated) and/or branch ducts (cysts connected to the ductal system). It may evolve to pancreatic cancer particularly if Wirsung is involved
IPMN subtypes :
Intestinal: main duct, head, 40%->coloid/tubular adenoca
Pancreatobiliary: main duct,head, 68%->tubular adenoca
Oncocytic: rare, nodules,50%-> coloid/tubular adenoca
Gastric: most frequent, branch-type, uncinate, 10%->tubular adenoca
https://t.co/CyvfrBGrXZ
IPMN: risk factors for malignancy
Main duct involvement (60% in resected specimens vs 10 to 30% in resected side branch IPMNs), specially>1cm
Contrast-enhanced mural nodules
Size>3-4cm
Symptoms
Pts at risk of PDAC even in other regions of the gland without involvement
👇👇👇
Intraductal papillary mucinous neoplasms -> management: follow these guidelines:
European guidelines 2018 @Gut_BMJ @chiaro_del @MarcBesselink https://t.co/x8waod12xr
Fukuoka 2017 @pancreatology@SalviaRobi https://t.co/PaEYljt5N9
Mucinous Cystic Neoplasms (MCN)
Characterized by mucinous epithelium and ovarian-type stroma, in body/tail
It is described as macrocystic, septated cyst with small number of cavities, it may have eccentric calcifications, no connection to ductal system
95% women, 5-7th decades
MCN:
>risk malignancy:
≥5cm
Nodules/mass
Thickened/irregular Wall
Calcifications
Management of MCN according to the European guidelines: a conservative approach is recommended for asymptomatic MCN measuring <40 mm without an enhancing nodule
https://t.co/x8waod12xr
@chiaro_del @MarcBesselink @Gut_BMJ
Serous cystic neoplasm (SCN). Cuboidal epithelium without dysplasia
70% women, 5-7th decades, NON-MUCINOUS solitary lesion
Classic SCN is microcystic (multiple small cysts, honeycomb-like) but can be macrocystic or solid. A central scar or calcification can be present
SCN management: remove only if symptoms, for example this case from @Dhgua, the patient had jaundice due to a a massive SCN, a Whipple procedure was performed
Cystic neuroendocrine tumor
It is a pancreatic NET with a central cystic changes. Solitary lesion, 5-6th decades, frequently with wall contrast enhancement, 10% malignant potential
Cystic neuroendocrine tumor management: asymptomatic and <2 cm you may follow the patient https://t.co/8EhhAet35T
It seems that these cystic NET are less aggressive than solid NET
Finally,solid pseudopapillary neoplasm
They have malignant potential(15%), >risk if >5 cm
Young women=90% (2-3rd decades),body/tail.Solid and cystic solitary masses, calcifications,often with intracystic bleeding.They can spread to the peritoneum or distant organs like the liver

THREAD: 12 Things Everyone Should Know About IQ

1. IQ is one of the most heritable psychological traits – that is, individual differences in IQ are strongly associated with individual differences in genes (at least in fairly typical modern environments). https://t.co/3XxzW9bxLE


2. The heritability of IQ *increases* from childhood to adulthood. Meanwhile, the effect of the shared environment largely fades away. In other words, when it comes to IQ, nature becomes more important as we get older, nurture less.
https://t.co/UqtS1lpw3n


3. IQ scores have been increasing for the last century or so, a phenomenon known as the Flynn effect. https://t.co/sCZvCst3hw (N ≈ 4 million)

(Note that the Flynn effect shows that IQ isn't 100% genetic; it doesn't show that it's 100% environmental.)


4. IQ predicts many important real world outcomes.

For example, though far from perfect, IQ is the single-best predictor of job performance we have – much better than Emotional Intelligence, the Big Five, Grit, etc. https://t.co/rKUgKDAAVx https://t.co/DWbVI8QSU3


5. Higher IQ is associated with a lower risk of death from most causes, including cardiovascular disease, respiratory disease, most forms of cancer, homicide, suicide, and accident. https://t.co/PJjGNyeQRA (N = 728,160)
प्राचीन काल में गाधि नामक एक राजा थे।उनकी सत्यवती नाम की एक पुत्री थी।राजा गाधि ने अपनी पुत्री का विवाह महर्षि भृगु के पुत्र से करवा दिया।महर्षि भृगु इस विवाह से बहुत प्रसन्न हुए और उन्होने अपनी पुत्रवधु को आशीर्वाद देकर उसे कोई भी वर मांगने को कहा।


सत्यवती ने महर्षि भृगु से अपने तथा अपनी माता के लिए पुत्र का वरदान मांगा।ये जानकर महर्षि भृगु ने यज्ञ किया और तत्पश्चात सत्यवती और उसकी माता को अलग-अलग प्रकार के दो चरू (यज्ञ के लिए पकाया हुआ अन्न) दिए और कहा कि ऋतु स्नान के बाद तुम्हारी माता पुत्र की इच्छा लेकर पीपल का आलिंगन...

...करें और तुम भी पुत्र की इच्छा लेकर गूलर वृक्ष का आलिंगन करना। आलिंगन करने के बाद चरू का सेवन करना, इससे तुम दोनो को पुत्र प्राप्ति होगी।परंतु मां बेटी के चरू आपस में बदल जाते हैं और ये महर्षि भृगु अपनी दिव्य दृष्टि से देख लेते हैं।

भृगु ऋषि सत्यवती से कहते हैं,"पुत्री तुम्हारा और तुम्हारी माता ने एक दुसरे के चरू खा लिए हैं।इस कारण तुम्हारा पुत्र ब्राह्मण होते हुए भी क्षत्रिय सा आचरण करेगा और तुम्हारी माता का पुत्र क्षत्रिय होकर भी ब्राह्मण सा आचरण करेगा।"
इस पर सत्यवती ने भृगु ऋषि से बड़ी विनती की।


सत्यवती ने कहा,"मुझे आशीर्वाद दें कि मेरा पुत्र ब्राह्मण सा ही आचरण करे।"तब महर्षि ने उसे ये आशीर्वाद दे दिया कि उसका पुत्र ब्राह्मण सा ही आचरण करेगा किन्तु उसका पौत्र क्षत्रियों सा व्यवहार करेगा। सत्यवती का एक पुत्र हुआ जिसका नाम जम्दाग्नि था जो सप्त ऋषियों में से एक हैं।
