7. Write short notes on the diabetic ketoacidosis

· - Absence of glucose in the tissues/cells for production of required energy, due to lack of insulin, stimulates the body to find the alternative source of energy.

· The other food substrate which is readily available as an alternative source is fats.

· Thus in the absence of insulin there is increased fat breakdown (lipolysis) in the effort to produce the required energy.

· Fatty acids are degraded in the liver, and in this process some of the by-products formed are ketone bodies.

· Ketone bodies (B-hydroxybutyric acid and aceto – acetic acid) in low concentration can be oxidized to produce energy.

· But in the absolute absence of insulin the rate of ketone bodies production exceeds the rate of their utilization and their levels rise in blood causing ketonaemia (hyperketonaemia).

· Ketone bodies further increase the plasma osmolarity causing cell dehydration and more thirst.

· They are acidic in nature and therefore offset body pH balance mechanism. This can result in severe ketoacidosis and often ketoacidotic coma

 

 

8. Define the following pathological terminology

(a) Balanoposthitis --- The term balanoposthitis refers to local inflammation of the glans penis and the overlying prepuce.

 

(b) Hypospadias - Hypospadias results from incomplete closure of urethral folds on the underside of the penis during embryological development.

 

(c) Epispadias -- The term epispadias indicates the presence of the urethral orifice on the dorsal aspect of the penis.

 

1. Write an essay on the epididymorchitis basing on the definition, causes and clinical presentation

 

  The epididymorchitis is general term used to denote inflammation of epididymis and testis.

The involved testis is typically swollen and tender and contains inflammatory infiltrate.

The affected testis is oedematous and congested and contains a predominantly inflammatory infiltrate.

Severe cases may be associated with considerable loss of seminiferous epithelium with resultant tubular atrophy, fibrosis, and sterility.

Testicular tuberculosis generally begins as an epididymitis, with secondary involvement of the testis.

The histological changes include granulomatous inflammation and caseous necrosis, identical to that seen in active tuberculosis in other sites.

Sexually transmitted diseases.

2. Write an assay on the pathogenesis of benign prostate hypertrophy basing on the following factors

· Androgens (testosterone and related hormones) are considered to play a permissive role in BPH.  This means that androgens have to be present for BPH to occur, but do not necessarily directly cause the condition.

· Dihydrotestosterone (DHT), a metabolite of testosterone, is a critical mediator of prostatic growth. This is synthesized in the prostate from circulating testosterone by the action of the enzyme 5α-reductase, type 2.

· This enzyme is localized principally in the stromal cells, hence, those cells are the main site for the synthesis of DHT.

· DHT binds to nuclear androgen receptors and signals the transcription of growth factors that are mitogenic to the epithelial and stromal cells.

· The importance of DHT in causing nodular hyperplasia is supported by clinical observations in which an inhibitor of 5α-reductase reduces prostate volume.

· Estrogens also play a role in the etiology of BPH.

This is based on the fact that BPH occurs when men have, in general, elevated estrogen levels and relatively reduced free testosterone levels, and when prostate tissue becomes more sensitive to estrogens and less responsive to DHT.

 

                     

3. Describe the types of wound healing

· It is a complex and dynamic process of restoring cellular structures and tissue layers.

· Wound healing process can be divided into 3 distinct phases

Inflammatory phase

Proliferative phase

Remodelling phase

· Within these three broad phases is a complex and coordinated series of events that includes chemotaxis, phagocytosis, granulation, collagen degradation, and collagen remodeling.

· In addition, angiogenesis, epithelization, and the production of new glycosaminoglycans and proteoglycans are vital to the wound healing.

 

Types of Wound Healing

There are three categories of wound healing which are:

· Primary wound healing

This is also known as healing by first intention.

Occurs within hours of repairing a full-thickness surgical incision when edges of the wound are in aposition.

· Delayed primary wound healing

Occurs if the wound edges are not reapproximated immediately.

By the fourth day, phagocytosis of contaminated tissues is well underway, and the processes of epithelialisation, collagen deposition, and maturation are occurring.

Foreign materials are walled off by macrophages that may metamorphose into epithelioid cells, which are encircled by mononuclear leukocytes, forming granulomas.

Chronic inflammation can ensue, resulting in prominent scarring.

· Secondary healing

This is also known as healing by secondary intention.

Secondary healing results in an inflammatory response that is more intense than with primary wound healing.

In addition, a larger quantity of granulomatous tissue is fabricated because of the need for wound closure
