3372. Covid-19 stories. The 83-year-old tissue selling aunty. Tissue seller
COVID-19 STORIES Dr Sing Kong Yuen, BVMS (Glasgow)
An 83-year-old tissue seller wore her face mask incorrectly
Tuesday Jul 14, 2020
“There is no need to worry,” the 83-year-old wheel-chaired, leathery faced tissue seller assured me that the mask wearing enforcers would not bother her as she had her face mask hanging loose around her neck. “Where have you been? I have not seen you for a long time!”
“You had been selling tissues since April 7 when the Covid-19 lockdown started?” I asked. “The government officers wheeled me home when they stopped me selling. I have started around 10 days ago.”
“You ought to wear your mask properly,” I told her that her mask's right ear loop was broken. It was knotted so that she could re-use it. She would not be protected from infectious Covid-19 viral droplets and aerosols from the various passers-by at this traffic junction. “Not to worry. You sounded like the enforcers!”
I gave her two new red disposable masks and money. She thanked me and wished me prosperity and good health. I had thought that she would not be selling tissue papers anymore after 3 months of lockdown, but here she was. Her eyes were tired but she told me she would rather not stay at home and stare at the four walls. Besides, the welfare bodies gave her $200 per month which was insufficient. In this job, she could meet people.
There were kind people who would give her $2.00 to buy a packet of tissue. Some gave her money.
One man usually bought her lunch. She suffered from paraplegia after an emergency intestinal surgery when she developed vomiting and diarrhoea after eating some food from the hawker stall.
The aunty did change to a new disposable face mask but did not use my two red ones.
Mask wearing is mandatory when outdoors until the end of the Covid-19 pandemic which is probably next year. The penalty for not wearing the face mask outdoors, unless permitted, is a $300 fine.

4132. An old dog has a fast growing head tumour - trichoblastoma. - histology
DRAFT SCRIPT for video production.
HOOK
Use footage 0:00 - 0:55 as hook and narrate the following below.

Prognosis for trichoblastoma is good with surgical removal as most do not become cancerous. However, there are rare cases of some being cancerous.
-----------------------------------------------
For the past 11 years, the Silkie Terrier had a small skin lump on her head. It slowly grew bigger over the years.
However, in the past 2 months, it grew much more. It became inflamed. See the big pinkish lump (pause this footage in the video).
The lump had changes in its cell structure as it grew bigger. Hence, it become extremely itchy.

The owner consulted Dr Daniel of Toa Payoh Vets on Dec 18, 2014.

Singapore is an island state of around 700 sq km. Small breed dogs are most popular as around 80% of the residents live in high-rise apartments.

Silkie terriers used to be a favourite breed as pets
in the past 10 years. Skin lumps develop as small papules and then nodules as the pet grows older. 
However, many of the baby boomer generation of owners do not have time to get their pets health checked after puppyhood as in this case study.

"My dog rubs her head tumour against the sofa many times!" the lady owner spoke loudly as was her usual habit. "She just can't stop doing it."

"The head of the lump is inflamed or red now," the vet explained. That inflammation cause itchiness. It can be a benign tumour like a cancerous tumour like basal cell carcinoma or an abscess.
"Surgery to cut it off is the only treatment.
"After cutting out the skin lump, send the lump to the laboratory for histology. Histology is the microscopic examination of the tissue cells to check whether it is cancerous or not.

The blood test did not show any abnormalities. The dog was fit for anesthesia. Dr Daniel used a scalpel to cut out the skin lump and sent it for histology.
HISTOLOGY is important to check:
1. whether the lump is cancerous or not. It was not cancerous.
2. whether it has had been completely cut out. In this case,
2. whether it has had been completely cut out. In this case,
the surgery completely removed it as Dr Daniel cut with 1-cm margin.
(Show the histology report and read:)
The tumour is completely excised. No overt malignancy is present.
Diagnosis: Suggestive of a trichoblastoma, not involving the resection margin.

What is a trichoblastoma?
The trichoblastoma is a benign cutaneous tumor that may derive from the hair germ of a developing follicle. It is common in dogs.
(SHOW AN IMAGE OF IT FROM THE VIDEO FOOTAGE)
(SHOW AN IMAGE OF IT FROM THE VIDEO FOOTAGE)
Trichoblastomas are usually present on the face and head as non-ulcerated nodules or papules. They are very rarely pigmented or cancerous.
Trichoblastoma may be inflamed and become itchy as in this Silkie Terrier.
On histology, trichoblastomas are large circumscribed basaloid tumors, located in the middle to lower dermis, without epidermal connection.
Tips and advices: (narrate image)
Trichoblastic carcinoma may appear similar to trichoblastomas clinically. However, on histology, there is significant asymmetry of the architecture, atypical mitotic figures, necrosis, and substantial infiltration of the tumor into the subcutaneous fat and muscle evident in trichoblastic carcinoma.
Hence early excision saves your pet's life.

HISTOLOGY CAN TELL WHETHER THE HEAD NODULE IS CANCEROUS OR NOT.
Basal cell carcinoma and trichoblastic carcinoma may appear similar to trichoblastomas clinically.
Basal cell carcinomas are malignant, proper diagnosis and management is important.
On histology, trichoblastomas are large circumscribed basaloid tumors, located in the middle to lower dermis, without epidermal connection.
The use of immunohistochemistry to show the staining patterns.
Histologically there are retraction spaces, atypia, and single cell necrosis in basal cell carcinoma. In addition, basal cell carcinomas do not stain for cytokeratin 20 and CD34 antigens. They also have diffuse staining of bcl-2 compared to peripheral staining seen in trichoblastomas.

Difficult to give tablet after surgery - excision of skin lump by Dr Daniel today. It is best to get small skin lump removed by your vet as some of them do turn malignant or irritate the dog. This dog was rubbing the skin tumour above the neck against the bed etc. for many years.
