Integrative management of insomnia during cancer chemotherapy: A case report.

INTRODUCTION: Insomnia is common among cancer patients, affecting about 50% undergoing cancer treatment. Insomnia can be due to various reasons, such as physical-pain, psychological-distress and medication side-effects. Insomnia has significant impact on quality of life of cancer patients. Even-though managed with hypnotics and antipsychotic drugs, they cause dependency with various short-term and long-term complications. Presenting a case throwing light on Ayurveda topical intervention as add-on to standard-of-care in insomnia during cancer chemotherapy. METHOD: A 51-year-old female patient with breast-cancer with extensive necrosis extending to subcutaneous areas was due for second cycle chemotherapy and was diagnosed with moderate-insomnia with a score of 21 as per Insomnia Severity Index in the Out-Patient-Department. Quality of sleep was assessed using Pittsburgh-Sleep-Quality-Index. Treated for 14 days during the break between cycle two and cycle three with Shirothalam (applied on the vertex) using Kachuradi Churnam with Kshirabala 101 and Padabhyangam (foot massage) using Kshirabala thailam as add-on to Tab Zolpidem5mg. Assessment was conducted on baseline and after 14 days of intervention. RESULTS: Assessment for insomnia before and after intervention was conducted with Insomnia-Severity-Index. The score improved from 21 to 2. Quality of sleep before and after intervention was assessed using global PSQI. It improved from 20 to 8. DISCUSSION: In Ayurveda, Nidranasam (loss of sleep) results from aggravation of Vata-Pitta (body humors responsible for movement and cognition and digestion, metabolism and heat of body), depletion of Kapha (body humor responsible for structural cohesion of body), derangement of Manasika-Dosa (mental constituents) and other diseases. All these etiological factors are attributed by Tikshna(sharp)- Ushna(hot potency) and Ruksha(dry) chemotherapy regimens. Vata-Pitta-hara (normalising Vata and Pitta) and Indriyaprasadaka (clearing senses) action of medicines used could induce sleep and effectively improve quality of sleep. CONCLUSION: Integrative-intervention was found to be beneficial in improving insomnia and quality of sleep without any reported complications or dependency in this case. After 14 days of ayurvedic intervention, the patient could get sleep even without taking zolpidem 5mg and external therapies. Same protocol could be considered for generalization so that it could modify or reduce usage of hypnotics and antipsychotic-drugs.

Revisiting the outstanding questions in cancer nanomedicine with a future outlook.

The field of cancer nanomedicine has been fueled by the expectation of mitigating the inefficiencies and life-threatening side effects of conventional chemotherapy. Nanomedicine proposes to utilize the unique nanoscale properties of nanoparticles to address the most pressing questions in cancer treatment and diagnosis. The approval of nano-based products in the 1990s inspired scientific explorations in this direction. However, despite significant progress in the understanding of nanoscale properties, there are only very few success stories in terms of substantial increase in clinical efficacy and overall patient survival. All existing paradigms such as the concept of enhanced permeability and retention (EPR), the stealth effect and immunocompatibility of nanomedicine have been questioned in recent times. In this review we critically examine impediments posed by biological factors to the clinical success of nanomedicine. We put forth current observations on critical outstanding questions in nanomedicine. We also provide the promising side of cancer nanomedicine as we move forward in nanomedicine research. This would provide a future direction for research in nanomedicine and inspire ongoing investigations.

Antibody–drug conjugate as targeted therapeutics against hepatocellular carcinoma: preclinical studies and clinical relevance

An antibody–drug conjugate (ADC) is an advanced chemotherapeutic option with immense promises in treating many tumor. They are designed to selectively attack and kill neoplastic cells with minimal toxicity to normal tissues. ADCs are complex engineered immunoconjugates that comprise a monoclonal antibody for site-directed delivery and cytotoxic payload for targeted destruction of malignant cells. Therefore, it enables the reduction of off-target toxicities and enhances the therapeutic index of the drug. Hepatocellular carcinoma (HCC) is a solid tumor that shows high heterogeneity of molecular phenotypes and is considered the second most common cause of cancer-related death. Studies show enormous potential for ADCs targeting GPC3 and CD24 and other tumor-associated antigens in HCC with their high, selective expression and show potential outputs in preclinical evaluations. The review mainly highlights the preclinical evaluation of different antigen-targeted ADCs such as MetFab-DOX, Anti-c-Met IgG-OXA, Anti CD 24, ANC–HN-01, G7mab-DOX, hYP7-DCand hYP7-PC, Anti-CD147 ILs-DOX and AC133-vcMMAF against hepatocellular carcinoma and its future relevance.

Ten-year survival outcome of breast cancer patients in India.

INTRODUCTION: Breast cancer is the most frequently diagnosed cancer among women in India; however, there are no studies addressing long-term survival (10 years and above). This study sought to evaluate long-term oncological outcome among women with breast cancer treated with a curative intent. MATERIALS AND METHODS: This is a retrospective cohort analysis of 1301 breast cancer patients of all stages who had received primary treatment with curative intent from 2004 to 2010 at a single cancer institution of India. RESULTS: A total of 1301 breast cancer patients were available for final analysis. The median age was 51 years (range, 21-86 years). 70.25% of the patients had early breast cancer (EBC), 21.9% had locally advanced breast cancer, and 7.85% of the patients with de novo metastatic disease also underwent surgery. 56.5% of the patients had hormone-sensitive tumors, human epidermal growth factor receptor 2 over expression was seen in 17%, and triple-negative tumors accounted for 26.2% of the patients. The 5- and 10-year overall survival (OS) of the entire cohort was 79% and 66%, and the 5- and 10-year breast cancer-specific survival (BCSS) was 79% and 70%, respectively. OS and BCSS were 51% and 58%, respectively, at 15-year follow-up after primary cancer treatment. On multivariate analysis, the factors associated with prolonged survival were age ≤50 years, EBC, and treatment during the later period (2008-2010). CONCLUSION: Difference between OS and BCSS was found to have an increasing trend during 10-15-year follow-up, the difference being 4% at 10 years and 7% at 15 years. Age ≤50 years, early-stage disease at presentation, and primary cancer treatment in later years (2008-2010) were favorable predictors for 10-year survival.

Primary Tumor Location as a Prognostic and Predictive Marker in Metastatic Colorectal Cancer (mCRC).

Clinico-pathological differences between adenocarcinoma in the right and left colo-rectum play a role in determining the prognosis and response to treatment. Studies suggest that primary tumor location is more relevant as the disease progresses and reflects a possible difference in biology and response to therapy. This review aims to explore the clinico-pathological features of right and left colo-rectum and the impact of primary tumor location on prognosis of CRC as well as discuss the available clinical data on tumor sidedness in metastatic colorectal cancer. In so far as the clinical data of tumor sidedness is concerned, very few reviews have discussed the clinical implications of sidedness in heavily pre-treated metastatic colorectal cancer (second and subsequent lines of therapy in metastatic disease). This review aims to fill the current gap in this setting.

Impact of St. Gallen surrogate classification for intrinsic breast cancer sub-types on disease features, recurrence, and survival in South Indian patients.

BACKGROUND: Breast cancer is a heterogeneous group of disease, and recently, intrinsic sub-typing on the basis of gene expression profiling is found to be a predictor of breast cancer clinical course. The St. Gallen has released surrogate classification for breast cancer sub-types depending on immunohistochemistry (IHC) markers. AIM: The aim of our study was to analyze the distribution of sub-types using IHC surrogate markers in our patient population and to assess the clinico-pathological factors in different sub-types. MATERIALS AND METHODS: A total of 635 non-metastatic patients who underwent radical intend treatment from January 2011 to December 2013 were included for this retrospective analysis. A statistical analysis was done by Windows SPSS version 20. The Chi-square test was used to examine the correlations of these sub-types with clinico-pathological parameters. The Kaplan-Meier method estimates were used for survival analysis. RESULTS: The median follow-up was 42.77 months (5 months to 112 months). Luminal B was the predominant group. Disease free survival (DFS) at 5 years was 95% in luminal A, 78% in luminal B HER-2 negative, 80% in luminal B HER-2 positive, 72% in triple negative, and 79% in HER-2/neu non-luminal. Tumor size, Ki67, T stage, N stage, and grade were significantly associated with DFS in all biological type with a P value of less than 0.05. CONCLUSION: Surrogate classification was successfully applied in our patient cohort. Luminal B and triple negative sub-groups were more prevalent in our patients, and this finding is at variance with published international data. Biological sub-type also emerged as an important predictor of survival.

A comparative study on erlotinib & gefitinib therapy in non-small cell lung carcinoma patients.

Background & objectives: Tyrosine kinase inhibitors (TKIs) targeting the epidermal growth factor receptor (EGFR) have been evaluated in patients with advanced non-small cell lung cancer (NSCLC). Erlotinib and gefitinib are the first-generation EGFR-TKIs for patients with NSCLC. However, there is a paucity of studies comparing the effectiveness of these two drugs. Hence, this study was aimed to compare the effectiveness and safety of erlotinib and gefitinib in NSCLC patients. Methods: This study included 71 NSCLC patients who received EGFR-TKIs between 2013 and 2016. Adverse drug reaction of both erlotinib (n=37) and gefitinib (n=34) was determined and graded according to Common Terminology Criteria for Adverse Events grading system. Effectiveness was measured using response evaluation criteria in solid tumours and progression-free survival (PFS). Pharmacoeconomic analysis was performed by cost-effective analysis. Results: When comparing safety profile, both the drugs had similar adverse events except for dermal side effects such as acneiform eruption (51.4%), rash (54.05%) and mucositis (59.5%) for erlotinib and 20.6, 26.5 and 29.4 per cent for gefitinib, respectively. The PFS of the two drugs was compared to differentiate the effectiveness of erlotinib and gefitinib. There was no significant difference between the effectiveness of the two drugs. The pharmacoeconomic analysis showed that gefitinib was more cost-effective than erlotinib. Interpretation & conclusions: This study showed that erlotinib and gefitinib had similar effectiveness but gefitinib had a better safety profile compared to erlotinib. Therefore, gefitinib could be considered a better option for NSCLC patients compared to erlotinib. However, further studies need to be done with a large sample to confirm these findings.

A Study on the Clinical Outcome of Abiraterone Acetate in Castration Resistant Prostate Cancer Patients.

Background: Abiraterone acetate was approved by FDA and EMA in April and September 2011, respectively for treatment of patients with casteration resistant prostate cancer and those previously treated with docetaxel. It is a selective inhibitor of androgen biosynthesis which potentially and irreversibly blocks CYP17, a crucial enzyme in oestrogen and testosterone synthesis. Materials and Methods: This retrospective study was conducted to evaluate the safety and efficacy of abiraterone acetate in the treatment of castration resistant prostate cancer patients. Twenty-two male patients diagnosed with CRPC and experienced treatment failure with one or more lines of treatment (hormonal manipulation or chemotherapy) were selected and administered abiraterone acetate (1,000 mg daily) along with prednisone (5 mg twice daily). Results: Out of 22 patients, 32% had a good response in reduction of PSA values, while 22% had progression in disease and 45% had a stable disease. Potassium, Haemoglobin, and serum sreatinine levels were not affected by the drug. Due to severe GI intolerance, the drug had to be stopped for one patient. The results of this study showed that abiraterone acetate significantly lowered the PSA values and prolonged progression- free survival in metastatic castration resistant prostate cancer patients who had progressed after first-line or second-line treatment. The overall average median survival and the median duration of drug exposure for CRPC who received AA was found to be 11.1 months [range 3-18]. Since AA plus prednisolone are available as oral dosage forms, they can be given in outpatient setting. Conclusion: Abiraterone acetate is a drug of choice for CRPC and also for those who had previously received one or two chemotherapy regimens. Since it is a new therapeutic regimen, this study included small sample size, but there are a few studies indicating the therapeutic efficacy of AA among patients with castration-resistant prostate cancer.

Short-course lenalidomide plus low-dose dexamethasone in the treatment of newly diagnosed multiple myeloma-a single-centre pragmatic study.

PURPOSE: We assessed response to treatment, toxicity, time to progression, progression-free survival, and overall survival in patients newly diagnosed with multiple myeloma who were ineligible for or unwilling to undergo transplantation and who were treated with a combination of lenalidomide and low-dose dexamethasone for a fixed 6 cycles in a resource-constrained environment. METHODS: This pragmatic study, conducted in a single tertiary cancer centre in South India, enrolled patients from May 2009 till April 2011. Treatment included lenalidomide 25 mg daily for 21 days, with dexamethasone 40 mg on days 1, 8, 15, and 22 of a 28-day cycle, for 6 cycles. Response was evaluated after the 3rd and 6th cycles of treatment. All patients were followed for 5 years. RESULTS: The study enrolled 51 patients. Median age in the group was 61 years (range: 38-76 years). Immunoglobulin G or A myeloma constituted 70.6% of the diagnoses, and light-chain myeloma constituted 29.4%. Stages i, ii, and iii (International Staging System) disease constituted 21.4%, 28.6%, and 50% of the diagnoses respectively. All patients were transplantation-eligible, but 34 (66.7%) refused for economic reasons. After treatment, 19.6% of the patients achieved a stringent complete response; 35.3%, a complete response; 5.9%, a very good partial response; and 29.4%, a partial response, for an overall response rate of 90.2%. Stable disease was seen in 3.9% of patients, and progressive disease, in 5.9%. Grade 3 or greater nonhematologic and hematologic toxicity occurred in 35.2% and 11.7% of patients respectively. Pulmonary embolism occurred in 1 patient. No patient experienced deep-vein thrombosis or peripheral neuropathy. The median follow-up duration was 66 months. All patients experienced disease progression. Median progression-free survival was 16 months. In 10 patients, re-challenge with lenalidomide and dexamethasone achieved a second complete response. At the time of writing, 19 patients had died. The overall survival rate at 5 years was 62.74%. Median overall survival is not yet reached. CONCLUSIONS: In a resource-constrained setting, lenalidomide with low-dose dexamethasone is an effective treatment with acceptable toxicity in patients newly diagnosed with multiple myeloma and not planned for transplantation. Complete responses were significantly more frequent than reported in the Western literature. Occurrence of clinical deep-vein thrombosis was rare, but hyperglycemia was common. An abbreviated course of treatment is suboptimal in multiple myeloma. Maintenance regimens should be advocated.

Esthesioneuroblastoma with intracranial extension: A non-surgical approach.

Esthesioneuroblastoma is a rare tumor arising from the olfactory mucosa of upper respiratory tract. The primary modality of treatment has been surgery with craniofacial resection followed by post-operative radiotherapy. There are only a few reported cases of non-surgical approaches. We report a case of esthesioneuroblastoma with intracranial extension treated with Vincristine, Adriamycin, Cyclophosphamide, Ifosfamide, Etoposide protocol followed by radiation with 5 years of follow-up. This is the first reported case using this chemotherapy schedule.

Surgical treatment pattern and outcomes in epithelial ovarian cancer patients from a cancer institute in Kerala, India.

OBJECTIVE: To evaluate the treatment and survival pattern of patients with advanced epithelial ovarian cancer. METHODS AND RESULTS: Retrospective study of all advanced epithelial ovarian cancer patients treated in the department of gynaecologic oncology from an academic centre, in a four year period from 1 January 2008-31 December 2011. SELECTION CRITERIA: All patients with advanced epithelial ovarian cancer (stage III and IV) who underwent surgery from 2008-2011and had a follow-up of at least three months after completion of treatment were included. The decision on whether primary surgery or neoadjuvant chemotherapy (NACT) in advanced ovarian cancer was based on age, performance status, clinical and imaging findings. RESULTS: A total of 178 cases of epithelial ovarian cancer were operated on during this four year period. Among them 28 patients were recurrent cases, 22 had early stages of ovarian cancer, and the rest 128 had stage III and IV ovarian cancer. In these 128 patients, 50(39.1%) underwent primary surgery and 78(60.9%) had NACT followed by surgery. In the primary surgery group 36(72.0%) patients had optimal debulking while in the NACT group 59(75.6%) patient had optimal debulking. With a median follow-up of 34 months, the median overall survival (OS) and progression free survival (PFS) was 53 and 49 months respectively. Patients who underwent primary surgery had better median PFS than patients who had NACT (56 months versus 39 months, p = 0.002). In stage III C the difference median PFS was significant for those treated with primary surgery when compared with NACT (55 months versus 39 months, p = 0.012). In patients who had optimal debulking to no residual disease (n = 90), primary surgery gave a significant improved PFS (59 months versus 38 months, p = 0.001) when compared with NACT. In univariate analysis, NACT was associated with increased risk of death (HR: 0.350; CI: 0.177-0.693). CONCLUSION: In advanced epithelial ovarian cancer, primary surgery seems to have a definite survival advantage over NACT in patients who can be optimally debulked to no residual disease.

A prospective comparison of perioperative morbidity in advanced epithelial ovarian cancer: Primary versus interval cytoreduction - experience from India.

OBJECTIVES: The objective was to compare perioperative morbidity and mortality of patients with advanced epithelial ovarian cancer (EOC) treated with either of the two treatment approaches; neoadjuvant chemotherapy (NACT) followed by interval debulking versus upfront surgery. DESIGN: Prospective comparative observational study. PARTICIPANTS: In total, 51 patients were included in the study. All patients with diagnosed advanced EOC (International Federation of Gynecology and Obstetrics IIIC and IV) presenting for the 1(st) time were included in the study. INTERVENTIONS: Patients were either operated upfront (n = 19) if deemed operable or were subjected to NACT followed by interval debulking (n = 32). PRIMARY AND SECONDARY OUTCOMES: Intra- and postoperative morbidity and mortality were the primary outcome measures. RESULTS: Patients with interval cytoreduction were noted to have significantly lesser operative time, blood loss, and extent of surgery. Their discharge time was also significantly earlier. However, they did not differ from the other group vis. a vis. postoperative complications or mortality. CONCLUSIONS: Neoadjuvant chemotherapy although has a positive impact on various intraoperative adverse events, fails to show any impact on immediate postoperative negative outcomes.

Potential use of drug loaded nano composite pectin scaffolds for the treatment of ovarian cancer.

Ovarian cancer is the ninth most common cancer amongst women and ranked as fifth in terms of the cause of cancer related mortality accounting for more deaths than any other cancer of the female reproductive system. Gemcitabine is the most common chemotherapeutic agent used in the treatment of ovarian cancer despite of its disadvantage of having a very lesser half life. In this study, we have envisaged the use of a highly porous, biomimetic and implantable pectin scaffold embedded with gemcitabine loaded fibrin nanoconstructs to improve the half life of the drug, thereby providing localized therapy for ovarian cancer. The controlled and sustained release of the chemokine from the scaffold system was extensively analyzed in vitro different pH environments. The composite scaffolds were found to be highly biocompatible when tested with mammalian cell lines. The excellent cytotoxicity and apoptosis responses induced in ovarian cancer, PA- 1 cell lines proved that the nanocomposite Pectin scaffolds loaded with specific chemokine can be used as implantable "therapeutic wafers" for distracting metastatic cancer cells and thus improve the survival rate of ovarian cancer afflicted individuals.

Factors associated with better survival after surgery in metastatic breast cancer patients.

Women with Metastatic Breast Cancer (MBC) and an intact primary have long been treated with systemic therapy alone. Local therapy is not considered unless for palliative reasons. However, several studies have suggested local treatment in the form of Surgery for the primary improves overall survival in certain groups of MBC patients. We evaluated the factors influencing the outcome in this group of patients. In a retrospective review of our prospective database, we identified the patients who presented with MBC and underwent surgery for primary tumour (2004-2009). Patients' surgical details and clinicopathological factors were reviewed. The overall survival of the MBC patients who underwent surgery was evaluated and compared depending on the various clinicopathological factors. Out of 196 patients with MBC, 48 underwent surgery of the primary tumor during their treatment course. Median overall survival was better in patients with young age (<=40 years), Estrogen receptor(ER) positive tumors (31.4 months vs 21.2 months), single metastatic site vs multiple metastatic sites (43.4 months vs 26.69 months). We also found that patients with low level of suspicion for metastases fared better than those with high level of suspicion (43.4 months vs 20.9 months). Our data analysis suggested that for MBC patients who undergo surgery, survival is significantly worse in patients with pathological T4 lesions and there is a trend towards better survival in younger patients and in those who have ER positive tumour, Her2neu negative tumour, single site of metastases and patients with low level of metastatic suspicion. However these factors need to be evaluated in a randomized trial comparing with patients who have not undergone surgery.

Carcinosarcoma of the uterus-a single institution retrospective analysis of the management and outcome and a brief review of literature.

Uterine carcinosarcomas are highly aggressive tumors of the uterus associated with a poor prognosis. Though initially classified as sarcomas, now these tumors are classified as carcinomas. The management approach of carcinosarcomas has also changed from those used for high grade sarcomas to that used for managing high grade endometrial carcinomas. The purpose of our study was to analyze the management and outcome of patients with uterine carcinosarcomas treated at our institution and also to attempt a brief review regarding the management of uterine carcinosarcomas. We did a retrospective analysis of all patients with a diagnosis of carcinosarcoma of the uterus treated at our Institution from January 2005 till December 2010. All Patients with a pathological diagnosis of carcinosacrcoma or malignant mixed mullerian tumours of the uterus were included. Data was obtained from the hospital electronic medical records and the hospital cancer registry. Data was analyzed using SPSS v.17. During this 6 year period we had 20 patients with carcinosarcoma of the uterus. 75 % of the patients belonged to Stage I and II. 95 % of the patients underwent Hysterectomy with Bilateral salpingo oophorectomy and 60 % had lymphadenectomy also along with hysterectomy.8 patients had disease recurrence . In patients who had gross extrauterine disease at the time of surgery , the survival was only 9 months whereas in patients who had complete staging with disease confined to the uterus , the survival was 36 months. Carcinosarcomas, accounts for more than 15 % of the uterine cancer associated deaths. Surgery remains the cornerstone of management for these tumors and surgery with pelvic and para aortic lymphadenectomy and peritoneal and omental biopsies is required for the correct staging of the disease and may also provide a survival advantage. Radiation therapy has been shown to provide only better local control without any survival advantage. Further studies are needed to assess whether chemotherapy offers a definite survival benefit in uterine carcinosarcomas.

Inflammatory myofibroblastic tumor of the lung: unusual imaging findings.

Inflammatory myofibroblastic tumor (IMT) is a rare neoplasm, most commonly seen in children and adolescents. It can occur in nearly every part of the body. Imaging properties and the clinical presentation of IMT can mimic malignant process. A 41-year-old female presented with cough of 3 months duration. Chest X-ray showed a coin shadow in the right upper lobe. Positron emission tomography/computed tomography scan showed a 3.2 × 2.4 cm lesion with homogeneous appearance with a very high fluorodeoxyglucose uptake value, suggesting a neoplastic process. She underwent lobectomy and the final diagnosis was IMT.

Gemcitabine and cisplatin-based combination chemotherapy in advanced hepatocellular carcinoma: An Indian experience.

BACKGROUND: Gemcitabine, an anti-metabolite, has some activity in hepatocellular carcinoma (HCC) in terms of responses and median survival. AIMS: To analyze our experience with the use of gemcitabine in combination with cisplatin in HCC with respect to response, toxicity and survival. MATERIALS AND METHODS: We studied the records of patients of HCC treated from January 2000 to December 2005 with gemcitabine and cisplatin, and found 24 of them to be evaluable for response, toxicity and survival. RESULTS: Of 24 patients receiving three or more cycles of chemotherapy, six (25%) had a partial response and an additional 12 (50%) had stable disease. The median overall survival (OS) was 7.5 months (95% confidence interval, 4.5-10.5 months) and 1-year survival was 18%. Grade 3 and 4 anemia, thrombocytopenia and neutropenia were observed in, respectively, 17, 17 and 33% patients. The most frequent non-hematologic toxicities were nausea and vomiting and peripheral neuropathy. CONCLUSION: We report a partial response rate of 25% with stable disease in an additional 50% to three or more cycles of chemotherapy with gemcitabine and cisplatin, with a median OS of 7.5 months (95% confidence interval, 4.5-10.5) and acceptable toxicity profile from our single-center retrospective study of 24 patients of HCC. We trust that, in HCC, gemcitabine is a good drug to be the foundation to build the chemotherapeutic or targeted agents' combinations on.

Herpes zoster: a clinical study in 205 patients.

BACKGROUND: Even though herpes zoster is a common condition its incidence and pattern of occurrence in the era of HIV disease is significant. AIM: To analyze the incidence, pattern of occurrence and evolution of herpes zoster with special attention to provocative factors if any. MATERIALS AND METHOD: This was an analytical study conducted for 2 years based on a preformed proforma containing preliminary information, a detailed clinical evaluation regarding the segment of involvement, morphology, pattern of lesions, complications, disseminations etc. and investigations to establish provocative factors if any. RESULTS: Incidence of herpes zoster was mainly in the fourth and third decades of life. A definite history of chicken pox was present in only 63.4% cases. In the majority (70%) herpes zoster occurred spontaneously. In 30% cases, immunosuppression due to chemotherapy, malignancy, HIV infection, diabetes mellitus were observed. The commonest segment affected was thoracic (42.4%) followed by cranial (28.2%) and cervical (12.1%). Majority resolved in 7-14 days except immunosuppressed. 34.6% of the patients had complications such as secondary bacterial infection, post herpetic neuralgia, and motor weakness. Ten patients had HIV infection as a provocative factor. CONCLUSION: The results of incidence and clinical pattern of herpes zoster is almost parallel to the previous studies. Any factors of immunosuppression should be checked, especially HIV, particularly in disseminated and long-lasting cases.
