had a nightmare where i broke my microscope by getting the slide stuck in the compartment that houses the ocular lenses (which is not actually possible, my dream microscope made no physical sense) and then i just left it like that and left lab to cry and didn't come back til the end.
no, I'm not stressed about my course load*, why do you ask?
*what i'm probably actually stressed about is the fact i couldn't get my eyes to see one image through the binocular lenses, no matter how i adjusted the distance between them, and worrying that i permanently fucked up my eyes during the height of the pandemic by not providing them enough variations in distance to look at.

Excuse my ugly face in the video lol
Today we had to find our “unknown” and find what it is and if it’s gram positive or gram negative. 
I first had to get the igniter outs as well as the Bunsen burner and my inoculating loop. I had to get my unknown broth which was number 13 (is also my lucky number and the day of my birthday as well), and dip my loop into the unknown broth tube. I then put the loop inside of the sample 13 tube, mixed it a bit then, put the mixture onto a clean slide in a circular motion. I then heat fixed it for 10 minutes and Gram stained it. Once gram stained, I was able to see I have a gram negative bacteria showing rods!
I also took the loop, Sanitized it with the Bunsen burner, and then put it back into the broth to put them on each of my Agar plates: EMB, MAC, & XLD.
On Wednesday we will see what grows on my plates whether it’s bacteria or fungi etc.

I have a patient who was on vancomycin and ceftriaxone for preseptal cellulitis of his right eye ("preseptal" means the eyeball itself is not affected, but the tissue around the eye is; if the eyeball itself is infected, that's a huge emergency). He ended up having pruritus and a rash, which was thought to be due to toxins released from the group A strep that he is infected with (Toxic Shock Syndrome). So vancomycin and ceftriaxone were discontinued. He was started on high-dose penicillin and clindamycin. Specifically, he was started on Unasyn (amoxicillin-clavulanate 3 grams IV q6 hours and clindamycin 900 mg IV q8 hours). The penicillin covers for the group A strep and the clindamycin covers for the toxins released by lysis of the bacteria. If he has toxic shock syndrome, he'll need steroids and IVIG. This is not my pt, but this is what preseptal cellulitis looks like:

This is from UpToDate:
Group A Streptococcus (GAS; Streptococcus pyogenes) is a gram-positive coccus that causes a broad array of infections. GAS is most commonly associated with pharyngitis or skin and soft tissue (non-necrotizing) infection; these are not typically associated with invasive infection. Less commonly, GAS causes invasive disease; invasive GAS infection refers to infection in the setting of culture isolation of GAS from a normally sterile site (most commonly blood; less commonly pleural, pericardial, joint, or cerebrospinal fluid). (See 'Introduction' above.)
●In resource-rich settings, there are an estimated 3.5 cases of invasive GAS infection per 100,000 persons, with a case-fatality rate of 30 to 60 percent. The incidence of invasive GAS infection is increasing; the factors responsible are not fully understood. Invasive GAS infection may occur in patients of any age; the incidence is highest in adults >50 years of age, followed by young children (particularly those <1 year of age). Most patients are not immunosuppressed. Invasive GAS infection usually occurs sporadically; however, clusters and outbreaks of invasive GAS infection have occurred. (See 'Epidemiology' above.)
●Clinical syndromes of invasive GAS infection (in absence of toxic shock) include necrotizing soft tissue infection, pregnancy-associated infection, bacteremia, and less common manifestations. GAS bacteremia usually occurs in association with infection at a primary site; the most common source is skin and soft tissue infection. In some cases, GAS bacteremia occurs in the absence of a clear localizing source. (See 'Invasive GAS infection (in absence of toxic shock)' above.)
●Invasive streptococcal infection should be suspected in patients with signs of systemic illness (such as fever) in the setting of skin or soft tissue infection. It should also be suspected in pregnant and postpartum women in the setting of high fever or rapid onset of fever. The diagnosis of invasive GAS infection is established via positive culture for GAS from a normally sterile site (most commonly blood; less commonly pleural, pericardial, joint, or cerebrospinal fluid). (See 'Diagnosis' above.)
●Streptococcal toxic shock syndrome (TSS) is a complication of invasive GAS disease characterized by shock and multiorgan failure; it occurs as a result of capillary leak and tissue damage due to release of inflammatory cytokines induced by streptococcal toxins. In general, invasive GAS disease is complicated by TSS in approximately one-third of cases; necrotizing soft tissue infection is complicated by TSS in approximately half of cases. (See 'Toxic shock syndrome' above.)
●Streptococcal TSS may present with a range of clinical features; these include hypotension, tachycardia, and fever. Hypothermia may be present. Altered mental status occurs in about half of cases. An influenza-like syndrome characterized by fever, chills, myalgia, nausea, vomiting, and diarrhea occurs in about 20 percent of patients. A diffuse, scarlatina-like erythema occurs in about 10 percent of cases. In addition, symptoms of underlying invasive GAS infection may be present. (See 'Clinical features' above.)
●Streptococcal TSS should be suspected in patients presenting with shock in the absence of a clear etiology. The diagnosis is established based on the clinical criteria and culture findings. Clinical criteria for streptococcal TSS include (1) hypotension (systolic blood pressure ≤90 mmHg in adults or <5th percentile for age in children <16 years) and (2) multiorgan involvement, characterized by two or more of the following: renal impairment, coagulopathy, liver involvement, acute respiratory distress syndrome, erythematous macular rash (may desquamate), and/or soft tissue necrosis (eg, necrotizing fasciitis, myositis, or gangrene). (See 'Diagnostic criteria' above.)
●A probable diagnosis of TSS may be made for cases that meet the above clinical criteria (in the absence of another identified etiology for the illness) with isolation of GAS from a nonsterile site (eg, throat, vagina, skin lesion). A confirmed diagnosis of TSS may be made for cases that meet the above clinical criteria, with isolation of GAS from a normally sterile site (eg blood, cerebrospinal fluid, joint fluid, pleural fluid, pericardial fluid, peritoneal fluid, tissue biopsy, or surgical wound). (See 'Diagnostic criteria' above.)
