2016. A guinea pig has urinary stone in the bladder then urethra - urethral obstruction

HOW TO PREVENT URINARY STONE FORMING IN YOUR GUINEA PIG? 
Part 1. Diagnosis and treatment. 


JULY 5, 2016.

"For the past 7 days, Whisky squeaked several times a day and night," Mr Ho, a divorced senior citizen said solemnly. "I thought he sought attention---like pre-schoolers throw tantrums to get parental attention. 


"But he drinks about 50% less water. His stools are normal but there are smaller stool sizes now.

"I took leave from my gardening job to bring my guinea pig to you for a check-up! I pray he is not in serious bad health,"

Mr Ho worked for a landscaping company as a gardener, trimming and caring for plants and flowers of big shopping malls. He was not your usual old man as he is fashionable. 

He wears a face mask to protect himself from inhaling fine dust and soil as Covid-19 virus was not present in 2016.
A broad brim hat to shield his sun-tanned face from the harsh sunlight. He was not the stereotypical frail and vulnerable  old people. 

"The guinea pig does not cry for attention many times a day," I palpated the 17-month-old male. Whisky shivered and moved away when I palpated the back half of his abdomen. This is where his bladder was located. I X-rayed his abdomen.

"Whisky was crying for help, actually," I told Mr Ho. "The pain was intense and that was why he sought you out for help!

"Whisky has a urinary tract infection as evident by the presence of reddish-brown urine seen when he was warded overnight. X-rays show a bladder stone." 

"I was too busy at work," Mr Ho shook his head. "Hence I delayed for 7 days. Can he be operated to get the stone removed?"  


"Not now," I advised. "Whisky has urinary tract infection and weight loss. He has to regain his health before a surgery to remove his bladder stone is to be done. He is not fit for anesthesia. He will die if he is operated today. 

Feed him antibiotics, painkillers and Critical Care by hand. Also around 500 ml of water a day 6 times a day. Whisky will be reviewed 7 days later." 


JULY 13, 2016.

However on the 8th day, Whisky could not walk. He could not pee too. He had not been eating by himself for the past 8 days. Mr Ho had to hand feed him.

X-ray showed the stone had lodged inside the urethra, obstructing any flow of urine. Hence he could not pee. I palpated his bladder which was a hard golf ball in size. 

Whisky would soon die of a ruptured bladder or kidney failure due to overflow of urine.

An emergency surgery was needed but the anaesthetic risk was so much higher. 

"Most likely, Whisky would die on the operating table. "You have to make the decision," I informed Mr Ho of the complications and a high probability of death on the operating table. He signed the anaesthetic and surgery consent form.

The cystotomy surgery was a success. I incised the bladder wall and extracted a small stone of 4-5mm in diameter lodged tightly inside the lumen of the urethra. 

However, Whisky passed away the next day. Mr Ho was very sad. Whisky was cremated. He kept the ashes in the urn.

I sent the urinary stone to the Minnestoa University Veterinary School to be analysed. It was a calcium carbonate stone.

Stones are usually formed as a result of feeding an unbalanced high calcium and protein diet. Obesity, drinking less water or withholding urine for long periods of time before peeing may be contributing factors.

3584. Brown butterflies - Horsfield's Baron Plant Melastoma malabathricum Ahoala aurea

 Host plant : Melastoma malabathricumLeaves, flower buds and flowers are shown.

Field Observations of Butterfly Behaviour:

The Horsfield's Baron is relatively common in Singapore. They are mainly found in the nature reserves, but at times adults can be seen flying in public parks and wastelands where the host plants are growing in abundance. Both sexes have the habit of resting on perches with wings open. The male exhibits territorial behaviour of chasing intruders in the vicinity of its perch. On rare occasions, the male have been observed to puddle on damp ground. Refer to this earlier butterfly-of-the-month article for a more detailed write-up on this species.


Early Stages:

The host plant, Melastoma malabathricum, is a widespread weed in Singapore. An earlier blog article has a detailed write-up of its characteristics and its relationship with other local butterfly species. Caterpillars of Horsfield's Baron feed on the middle-aged to mature leaves of this amazing plant.

Arhopala aurea

Family:Lycaenidae
Subfamily:Lycaeninae
GenusArhopala
Species:aurea
Life History:incomplete
Extant in countries:•Singapore

Description
The males of this Arhopala species have forewings with a rather acute apex, unlike the usual Arhopala wing shape. However, the females possess the usual Arhopala characteristics in having rounded forewings.

The male of Arhopala aurea is a bright coppery green above with a slight basal bluish scaling. The hindwing border is broad and irregular and the green scaling does not reach the termen.

The female is purple-blue above in the usual Arhopala fashion. Both sexes have short stumpy tails with tornal green scales.

Habitat & Habits
Arhopala aurea, and another closely related species, Arhopala trogon are reported to be less uncommon in Singapore than on mainland Malaysia. Indeed, this is still the case, as the species are still evident in certain parts of the nature reserves even as recent as November 2001.

3583. Photography tips - Use P Mode

ADVICES FOR YOUNG PEOPLE

Learn digital photography. It is a very useful skill.

Use a DSLR camera. “M” mode is difficult for beginners as they have to use the correct aperture, shutter speed and ISO. Lighting changes fast and the settings may be out of date resulting in a mediocre image.

Most of my photos are set to “P” Mode, Auto Focus, single point focus. I focus on the “eye” of the person on the left, steady hands are needed (SGH, 3 pm, bright sunlight, 12 Apr 2021). The “P” Mode will automatically set your aperture, shutter speed and ISO.                                                                        @davidsing1

 

 

ADVICES FOR YOUNG PEOPLE.
Learn digital photography to create good images in your career or home. It is a very useful skill as the vast majority will just use the handphone to click images and not develop deeper skills.

Use a DSLR camera. “M” mode is difficult for BEGINNERS because you need to set the correct aperture, shutter speed and ISO. By the time you do it, the lighting may have changed from bright to dark. In "P" mode, you don't have to do the settings.

Most of my photos are set to “P” Mode, Auto Focus, single point focus. I focus on the “head” of the mother with 2 sons; steady hands are needed. The “P” Mode will automatically set your aperture, shutter speed and ISO.  See example in this post.

3581. Singapore, a nation by design. Design thinking approaches

ST 1 Mar 2021. B3. 


1. Singapore University of Technology and Design offers a unique design-centric and interdisciplinary education.

2. More broadly, to make this approach pervasive in our businesses, community and the Government such as the Infocomm Media Development Authority's Pixel Design Thinking programme, where companies keen to apply design thinking methodologies can receive support to start a digital innovation project or to facilitate their design innovation process.

3. Encourage problem-solving and critical thinking in our schools, through approaches such as project work. 

4. Ultimately, design thinking is a habit of the mind that should be developed and infuse it into our approaches to problem-solving and innovations so as to ensure that our products, policies or programmes continue to meet the needs of our customers and citizens.

3580. Overgrown front tooth dwarf hamster

13 Apr 2021. VETERINARY STORIES FOR VET STUDENTS AND PET OWNERS by Dr Sing Kong Yuen, BVMS (Glasgow). HOW DOES TOA PAYOH VETS TREAT OVERGROWN FRONT TEETH IN DWARF HAMSTERS? 

ABOUT THIS CASE

The dwarf hamster’s front teeth grow continuously to old age. They are worn down when it gnaws on seeds. The young lady surfed the internet to locate a vet who does hamster dentistry as her vet will not treat hamster.

Gas anaesthesia is needed to trim the overgrown tooth safely for the hamster. A rodent’s tooth cutter and forceps are used.

Advices include change to more seeds and no grilles in the cage to prevent gnawing causing overgrown teeth. 

Extra anaesthetic care is important as the hamster can die from anaesthesia or heat loss during or post surgery.
