Ulcerative Colitis

 

The diagnosis of UC is best made with endoscopy and mucosal biopsy for

 histopathology. Laboratory studies are helpful to exclude other diagnoses and assess

 the patient's nutritional status, but serologic markers can assist in the diagnosis of

 inflammatory bowel disease. Radiographic imaging has an important role in the

 workup of patients with suspected inflammatory bowel disease and in the

 differentiation of UC from Crohn disease by demonstrating fistulae or the presence of

 small bowel disease seen only in Crohn disease.

Orbital Cellulitis

Peri-orbital and orbital cellulitis are distinct clinical diseases, though have overlapping clinical features and therefore can be difficult to differentiate

• Orbital cellulitis: Infection within the orbit, (ie post-septal, the structures posterior to the orbital septum); Surgical emergency with major complications including loss of vision, abscess formation, venous sinus thrombosis and extension to intracranial infection with subdural empyema, and meningitis; & the majority (>80%) of cases relate to local sinus disease.
• Peri-orbital cellulitis: Infection of the eye lids and surrounding skin not involving the orbit (ie pre-septal, the structures anterior to the orbital septum)
• The globe is not involved in either infection.

The causative organisms, commonly bacterial but can also be polymicrobial, often including aerobic and anaerobic bacteria and even fungal or mycobacteria. The most common bacterial organisms causing orbital cellulitis are Staphylococcus aureus and Streptococci species. Rare cases of orbital cellulitis caused by non-spore-forming anaerobes Aeromonas hydrophila, Pseudomonas aeruginosa, and Eikenella corrodens have also been reported. 

 

MSSA and MRSA

Methicillin-Sensitive Staphylococcus aureus (MSSA) and Methicillin-Resistant Staphylococcus aureus (MRSA). 

MSSA arrived quietly, without unnecessary drama. Predictable and courteous, he followed the usual clinical trajectory of fever, positive blood cultures, appropriate management, and steady improvement. The team appreciated his transparency; he respected the rules of engagement and left promptly once his source was addressed. There were no consult wars, no prolonged discussions but just a clean resolution and a satisfied discharge summary.

MRSA, however, was a different story altogether. He entered the bloodstream with confidence and defiance, fully aware of his reputation. The moment his name appeared on the microbiology report, the atmosphere changed. The primary team sighed, pharmacy frowned, and infection control started whispering about isolation protocols. MRSA thrived on attention and turning every simple bacteremia into a multidisciplinary production involving ID, nursing, infection prevention, and sometimes even hospital administration. He lingered longer than anyone wanted, testing the limits of patience, policy, and resource allocation. With coordinated teamwork, careful management, and more meetings than anyone cared to count, MRSA was finally cleared from the bloodstream.

MRSA-PCR

Picture MRSA-PCR as the hospital’s ultimate crime-fighting superhero team, but instead of capes and laser eyes, it wields test tubes and genetic scanners. MRSA the notorious “bad boy” of bacteria, likes to sneak into hospitals, pick fights with antibiotics, and then hide in plain sight like a germy ninja. Old-school tests stumble around like detectives in a black-and-white movie, muttering “the culture will be ready in a few days,” while MRSA laughs and throws confetti in the background.

😷⚕️⭐️But PCR? Oh no, PCR doesn’t waste time. It storms in like a caffeinated detective on double espresso, grabs a swab, and yells: “Aha! There’s the MRSA DNA, hiding in your nose like it pays rent!” In just hours, the mystery is solved, the bacteria is busted, and the lab gets to feel like it just solved the medical equivalent of a bank heist. Fast, flashy, and way more reliable than waiting around for Petri dishes to gossip, MRSA-PCR is basically the hospital’s drama-filled reality show where the germs always get exposed.

 

Drug Induced Hyponatremia

 

Think of sodium as the ultimate event planner in your body, the one who keeps everything orderly, balanced, and running on time. Sodium knows how to keep water in the right places: not too little, not too much, just the perfect hydration vibe. It’s like that one responsible friend who prevents the party from getting out of control.

Now, here’s where the drama starts: certain medications like thiazide diuretics, SSRIs, carbamazepine, and their buddies decide they know better. Instead of appreciating sodium’s years of experience, they“reassign” it, often flushing it away or silencing its role in water regulation. It’s like firing the competent manager and hiring an overenthusiastic intern.

With sodium out of the picture, water seizes the opportunity. It floods the party like uninvited guests crashing a wedding buffet pouring into cells, especially in the brain. At first, the brain cells are polite, trying to squeeze in a little extra water. But soon they swell like overfilled balloons, and the nervous system throws a fit: headaches, confusion, unsteady gait, seizures and in severe cases, a medical emergency that’s about as fun as a power outage during surgery.

The irony? This whole watery rebellion isn’t caused by an exotic tropical disease or some rare genetic mutation it’s often the very “helpful” medications prescribed to make life better. That’s drug-induced hyponatremia: when well-meaning pills accidentally kick sodium out of its leadership role, and water runs the show like a toddler hyped on sugar.

So, the moral of the story? Respect sodium, it may be small, but it’s mighty. And always keep an eye on those meds, because sometimes the cure sneaks in with a side hustle as the troublemaker.

Mitral valve regurgitation

 Mitral valve regurgitation is the heart’s version of a plot twist — just when you think everything’s flowing forward, boom, blood decides to moonwalk back into the left atrium. Picture the mitral valve as a pair of elegant French doors between the left atrium and ventricle: they’re supposed to swing shut with precision and class. But in MR, one or both of those doors get a little loose, floppy, or just plain defiant — thanks to degenerative disease, ischemic insults, or the occasional rheumatic meddler still hanging around like it’s the 1940s. The result? Blood backflows during systole, the atrium gets flooded like a poorly planned basement, and the ventricle starts pumping harder than a med student during exam week just to keep up. Clinically, it’s a delicious mix of holosystolic murmurs, volume overload, atrial fibrillation auditions, and left ventricular eccentric hypertrophy trying to make it all work. And let’s not forget the symptoms — fatigue, dyspnea, and that glorious pulmonary congestion that says, “I’m leaking but fabulous.” Diagnosis by echocardiography turns into a cardiac detective story, and treatment spans the spectrum from medical finesse to surgical drama, complete with valve repair or replacement. So while MR might sound like just another leaky valve, in the world of internal medicine and cardiology, it’s a charismatic troublemaker — dramatic, unpredictable, and never boring.
