Understanding Penicillin Variants
Recently, my five-year-old son finished a ten-day regimen of phenoxymethylpenicillin to address a persistent tonsillitis. However, in the final two days of this antibiotic treatment, he started to notice some discharge coming from one of his eyes. After a follow-up visit to our physician, we were given a prescription for amoxicillin. How exactly could an eye infection occur while he was undergoing treatment with penicillin? Furthermore, is amoxicillin expected to provide any different benefits in combating this eye infection compared to phenoxymethylpenicillin?

I understand your concerns about your son transitioning from phenoxymethylpenicillin to amoxicillin, especially with the occurrence of eye discharge. Let's break this down for clarity.
Key Points
-
Possible Eye Infection During Treatment: It is possible for an eye infection to develop even while taking antibiotics for a different bacterial infection. The antibiotics prescribed may be effective for tonsillitis but do not cover all potential infections. If your son was exposed to other bacteria, for instance, through touching his eyes or from environmental sources, an eye infection could still occur.
-
Differences Between Antibiotics:
- Phenoxymethylpenicillin is often effective against certain bacteria that cause throat infections like tonsillitis.
- Amoxicillin has a broader spectrum of activity and can be particularly effective against certain eye infections, such as those caused by the same bacteria that could influence his tonsillitis or conjunctivitis (often referred to as pink eye).
Next Steps
-
Continue Amoxicillin as Prescribed: Follow your physician’s advice and administer the amoxicillin as prescribed to target the eye infection effectively.
-
Monitor for Symptoms: Keep an eye on any changes in your son’s condition, including:
- Improvement in the eye discharge.
- Any signs of redness or swelling around the eye.
- Changes in overall health, such as fever or increased irritability.
-
Eye Care: To help manage the eye discharge, you can:
- Gently clean the area around his eye with a soft cloth to remove any crusting, using warm water.
- Avoid touching or rubbing the eyes to minimize irritation or spread of infection.
-
Follow Up: If the discharge persists, worsens, or if he develops additional symptoms (such as extreme discomfort or vision changes), consider contacting his healthcare provider for further guidance.

Inquiry Regarding FDG-PET Scan Findings
I recently underwent an FDG-PET/CT scan for my brain to investigate some cognitive difficulties I've been experiencing. Although the report is now available on My Chart, my follow-up appointment with the doctor is scheduled for three weeks from now. I have a query regarding the standard deviation scale presented in the report, which lists values from -2 to -4.6. What does the lowest value signify? Is the scale graded on a 1-5, 1-10, or perhaps 1-100 basis? I appreciate your assistance with this! Notable regions noted for decreased metabolic activity include: - Left Inferior frontal gyrus, triangularis: SD "4.6" - Left Heschl gyrus: SD "3.8" - Left Superior temporal gyrus: SD "3.6" - Left Middle temporal gyrus: SD "3.4" - Left Supramarginal gyrus: SD "2.6" - Left Inferior parietal lobule, supramarginal area: SD "2.1" Other areas displaying low metabolism are: - Right Superior frontal gyrus, medial: SD "3.2" - Left Superior frontal gyrus, medial: SD "2.2"
Seeking Clarity on a Pediatric Surgical Experience
One of my earliest recollections involves surgical gauze wrapped around my genitals and being cautioned to exercise caution regarding my circumcision. This incident dates back to around 1972, when I was roughly three years old. My brother, who was eleven at the time, corroborates this memory and recalls that the bandage remained in place for "a few weeks." His recollection is a bit unclear, but he does remember seeing me running around without pants and with a gauze dressing. He believes the dressing wasn't overly bulky and doesn't recall any stent being used. However, I am aware that his memory may not be completely accurate based on other conversations we've had. He recalls being informed that I underwent surgery for an undescended testicle, yet was never made aware of a circumcision being involved. Later, a physician indirectly confirmed that I had undergone an early orchidopexy. This memory piques my curiosity, particularly since my parents have never brought it up with me. I have knowledge of having glanular/coronal hypospadias, and the details of my situation appear to align with images I’ve encountered depicting partial hypospadias corrections. This leads me to wonder if my circumcision might have actually been related to hypospadias surgery. Unfortunately, any tangible proof of these events was lost when I underwent gender confirmation surgery as a trans woman three decades ago. It's conceivable that the standard circumcision procedure typically performed at birth could have been postponed, given that I was born slightly premature and had significant Rh disease and hypoxia. But could it have been deferred until I reached the age of three? I have made attempts to obtain my medical records, but unfortunately, they have been destroyed over the years. While I understand that definitive answers may be elusive, I would greatly appreciate any insights or thoughts on this matter.
Concerns About Potential Peripheral Artery Disease (PAD)
For the past three to four years, I have been dealing with a persistent numbness in my left foot. Initially, I suspected it might be due to a pinched nerve or perhaps something similar, but the sensation has never completely returned. As time has gone by, I've encountered additional worrying symptoms: - My feet have started to develop a purple hue, particularly evident when I sit in positions that put pressure on my legs or when I take a shower. This discoloration has become one of the most alarming signs of my condition. - The growth of my toenails has slowed considerably, and they now appear uneven and ridged. - Additionally, my feet have a temperature that feels significantly colder than the rest of my body, and they no longer grow hair as they once did. I do not smoke and I’m not diabetic; however, I have high cholesterol and received an elevated result on a lipoprotein test. The prospect of PAD is frightening to me, as it seems synonymous with a grim future. I have been referred to a cardiologist, but they are reluctant to conduct an Ankle-Brachial Index (ABI) test since I am under 35. I want to remain hopeful and believe I don't have PAD, yet I struggle to identify any other plausible explanations for these symptoms. What could be potential alternatives to consider, if any exist?
Unexplained Left Chest Pain, Electric-Like Jabs in Lower Back, and Unusual Headaches
Hi there, I’m a 15-year-old experiencing some peculiar health issues lately. A visit to my doctor led to a diagnosis of anxiety and poor posture after I complained about headaches and strange, electric sensations rising through my head. However, after that appointment, I became aware of pain in my heart and strange discomfort in my left chest accompanied by difficulty breathing. Initially, I thought these symptoms aligned with anxiety, but they persisted long enough to cause concern. To rule out any serious conditions, I underwent a blood test, which fortunately came back normal. Despite the positive results, I continued to feel unusual pains in my heart region and a peculiar ache in my lower abdomen. The doctor had previously mentioned my poor posture and identified an issue with my occipital nerve, which I’ve somewhat addressed. Now, though, I find myself having intermittent back pain and brief discomfort just beneath my left lung. These pains are indeed strange; they don’t always last long, sometimes just fading after five seconds or they might stick around for several minutes. I tend to spend a lot of time in bed and don’t often leave the house, yet when I do, these pains still occur. Thankfully, they aren’t debilitating, but I can't help but feel anxious thinking something might be significantly wrong with my health. It’s unsettling and I’d prefer not to dwell on such thoughts. To summarize: I experience chest pain in my lower left quadrant, specifically near my lung, alongside a mild but uncomfortable sensation that waxes and wanes. Additionally, I suffer from headaches located on the upper left side of my head. I apologize for any grammatical errors as I used voice-to-text for this message. Another detail that might be relevant is that I have recently quit vaping, now almost 22 days ago, and I wonder if this could be part of the recovery process.
Expectorated Large Tissue with Blood
At 28 years old, I experienced a fever the previous night, after which I had no other cold symptoms. To my surprise, today I coughed just once and expelled a significant piece of tissue mixed with blood. Following this alarming incident, I sought medical attention at an urgent care facility because I developed a headache immediately afterward and felt a peculiar "butterfly" sensation in my chest. The healthcare professionals did not conduct any laboratory tests or imaging studies, instead opting to prescribe antibiotics for what they suspected might be an infection. Is this an appropriate response to my situation? This is quite concerning.
